In addition, in the line production system 100 according to present embodiment, equipment to be adjusted is of processing machine 5a to 5b, of machine table 3a to 3l, or of measuring machine 6a to 6c.In addition, below, will the detailed structure of adjusting gear 7 be described.
(structure of adjusting gear)
As shown in Figure 1, the adjusting gear 7 according to present embodiment has information memory cell 12 (memory device), receiving element 11, add up to unit 13, identifying unit (identifying unit) 21, histogram feature detecting unit (distribution character computing unit) 15, rejection rate arithmetic element (each rejection rate computing unit) 14, cycle information detecting unit (cycle detection unit) 16, unusual estimation unit (designating unit) 17, instruction output unit (output unit) 19, adjustment unit (change indicating member) 18, state changes detecting unit 20 and setup unit (change unit) 22.
But information memory cell 12 is readable/write record media, and for example, can be realized by flash-EEPROM (EEPROM (Electrically Erasable Programmable Read Only Memo)) or the like.In information memory cell 12, the characteristic value 31 that record is received by receiving element 11 and be the device initial value 32 of the setting value that in each processing machine 5a and 5b, is provided with in advance.
In addition, setting value is each the value of operation that is used to define processing machine 5a and 5b, and by changing this setting value, changes the processing result of goods.For this reason, when changing setting value, change the characteristic value 31 of the goods of the processing machine 5a that changes by its setting value or processing machine 5b processing.
In addition, in information memory cell 12, although not shown in Fig. 1, also record is used to carry out the predetermined threshold information of the estimation of handling abnormal cause.
In addition, in information memory cell 12,, also write down the warning notice of using when the estimation of carrying out following abnormal cause when unusual estimation unit 17 is handled although not shown.
In addition, in information memory cell 12, although not shown, also be recorded in change before the setting value according to by the histogrammic information of the characteristic value of the goods of processing machine 5a or processing machine 5b processing, after changing setting value according to by histogrammic information of the characteristic value of the goods of processing machine 5a or processing machine 5b processing or the like.Histogram information is that the adjustment of following setting value is handled, so that change one the required information of setting value of processing machine 5a and 5b.
In addition, above-mentioned characteristic value 31, device initial value 32, threshold information, warning notice and histogram information can be stored in each recording medium that provides separately maybe can be provided in the independent information memory cell 12, in internal memory.
In addition, if can pass through communication network,, it can be configured to obtain above-mentioned information from external unit with external device communication according to the adjusting gear 7 of present embodiment.
Receiving element 11 receives the measurement characteristics value 31 of goods from each measuring machine 6a to 6c.Receiving element 11 makes the characteristic value 31 that received and distributes to the channel number of each measuring unit 6a to 6c in the source of characteristic value 31 and related by the Measuring Time of each measuring machine 6a to 6c measurement characteristics value 31, is stored in the information memory cell 12.
Add up to unit 13 to read characteristic value 31, and add up to the characteristic value 31 that is used for each measuring machine 6a to 6c, or add up to the measurement characteristics value 31 that is used for all goods from information memory cell 12.That is, add up to the aggregate result of unit 13, calculate product amounts and substandard products quantity, and produce histogram based on the characteristic value 31 of each channel number that is used for measuring machine 6a to 6c.In addition, according to the characteristic value 31 of all measurements, add up to unit 13 to calculate measured product amounts and substandard products number and generation histogram.
Identifying unit 21 judges whether to carry out the estimation that is used for abnormal cause and handles based on the aggregate result by all characteristic values 31 that add up to unit 13.That is, identifying unit 21 is based on characteristic value 31, confirms exists/not exist not at goods and satisfies characteristic value 31 in the scope of scope (hereinafter, being called specialized range) of the characteristic value of definite quality, and judge whether to carry out the estimation processing that is used for abnormal cause.In addition, use description to the details of the estimation processing of abnormal cause below.
In addition, about judging, if even there is a not characteristic value 31 in specialized range, identifying unit 21 can be judged the estimation processing of execute exception reason.In addition, when confirming there is not the characteristic value 31 in specialized range with a certain ratio, identifying unit 12 can judge that the estimation of execute exception reason handles.Best, according to the quality that obtains from fabricated product, determine determinating reference.
Wherein, measured goods number is a quantity of being measured the goods of its characteristic value 31 by measuring machine 6a to 6c in predetermined period.For example, suppose 300 goods of processing in predetermined period.In this case, the characteristic value 31 from fabricated product is measured on three three ground of measuring machine 6a to 6c simultaneously.Therefore, the quantity by each the measurement goods among the measuring machine 6a to 6c is 100.In addition, the quantity of the measurement goods that obtain from all measuring machine 6a to 6c is 300.
In addition, the substandard products number is the quantity that its measurement characteristics value is identified unusual goods.That is, in line production system 100, pre-determine the scope that fabricated product satisfies the characteristic value of definite quality, i.e. specialized range (regular range).Then, from measurement characteristics value 31, the goods number corresponding with the characteristic value in this scope not 31 becomes the substandard products number.
Histogram is represented to be distributed by the frequency (frequency n) of the characteristic value 31 of the goods of the measurement of measuring machine 6a to 6c.That is,, the scope division of characteristic value is become a plurality of parts (y), and show and be included in the frequency (frequency n) that each divides the characteristic value 31 in the part with reference to figure 2A and 2B.
When identifying unit 21 judges that when having not the characteristic value in specialized range, property of the histogram detecting unit 15 detects the distribution characteristics of respective histogram based on by the histogram that adds up to unit 13 to create.
For example, when all goods of normal process by processing machine 5a to 5b, and the normal measurement processing of carrying out the characteristic value 31 that is used for fabricated product, that is, under normal condition, shown in Fig. 2 A, all characteristic values 31 are all in the scope of α to β.In addition, the scope of α to β is represented specialized range, and wherein, α is the lower limit of specialized range, and β is the higher limit of specialized range.
Therefore, by adding up in the histogrammic distribution that characteristic value 31 creates, occur and compare, increase a part (the some A in Fig. 2) of goods number in preceding or next part.That is, usually, when fabricated product satisfied definite quality, frequency had near the maximal value the intermediate value of specialized range alpha-beta.In addition, hereinafter, in histogram distribution, with a category-A seemingly, will with compare in preceding or next part, the part that increases goods is called peak value.
On the other hand, when normal process goods not, or when accurately not measuring the characteristic value 31 of fabricated product, that is, under the situation of abnormality, histogram distribution is shown in Fig. 2 B.That is under abnormality, shown in Fig. 2 B, a plurality of peak values (peak A 1, peak A 2) appear or exist to have the not goods of the characteristic value in the scope of specialized range alpha-beta 31.
For example, as processing machine 5a and processing machine 5b all not during normal running, in the characteristic value 31 by the mach goods of processing of not normal running, the frequency of part that departs from the intermediate value of specialized range alpha-beta has maximal value.For this reason, in histogram that forms according to the characteristic value 31 by the mach goods of processing of normal running and the histogram that formed by the characteristic value 31 of the mach goods of processing of not normal running, the part of peak value appearance is not aligned with each other, but departs from each other.
Therefore, under the situation of abnormality, shown in Fig. 2 B, two peak values appear in histogram.
Similarly, the characteristic that has according to the characteristic value 31 of the characteristic value 31 of goods in normal condition or the goods in abnormality of the histogram of being created distributes.
Wherein, histogram feature detecting unit 15 based on by the histogram that adds up to unit 13 to produce, is analyzed peak value according to the indication from identifying unit 21.Then, histogram feature detecting unit 15 is sent to unusual estimation unit 17 with the peak value of being analyzed.
When identifying unit 21 was judged the characteristic value 31 that exists in the specialized range not, rejection rate arithmetic element 14 was calculated the rejection rate of measured characteristic value 31.That is, rejection rate arithmetic element 14 calculate the characteristic value 31 measured by each measuring machine 6a to 6c each rejection rate and the rejection rate that is used for all measurement characteristics values 31.
In addition, rejection rate arithmetic element 14 can be carried out the arithmetical operation by following equation (1) expression according to the characteristic value 31 of all characteristic values 31 and each measuring machine, so that calculate rejection rate.
NGRation=(N_i-OK_Num_i)/N_i (1)
NGRation: rejection rate
OK_Num_i: in the measurement result of the processing machine by having channel number i, the quantity of the characteristic value 31 in specialized range, or in the measurement result by all measuring machines, the quantity of the characteristic value 31 in desired extent.
N_i: the quantity of the characteristic value of measuring by measuring machine 31, or the quantity of the characteristic value of measuring by all measuring machines 31 with channel number i.
Then, rejection rate arithmetic element 14 will be sent to unusual estimation unit 17 by the rejection rate of carrying out the arithmetical operation acquisition according to aforesaid equation (1).
The relation that the serial number of 16 inspection processing of cycle information detecting unit and measurement goods and the characteristic value of goods are 31.More particularly, cycle information detecting unit 16 is by carrying out arithmetical operation according to following equation, the periodicity of the relation that the serial number of detection processing and measurement goods and the characteristic value of goods are 31.
In line production system 100, constantly transmit from the goods of goods inlet 1 input in order according to present embodiment.In addition, three measuring machine 6a to 6c are configured to the input sequence number of basis by the order of measuring machine 6a, measuring machine 6b and measuring machine 6c, measure goods.
In addition, related with measurement characteristics value 31 in information memory cell 12 as mentioned above, the measurement date of channel number and the characteristic value 31 of each measuring machine 6a to 6c distributed in record.
Therefore, the date and the channel number of each of reference measure machine 6a to 6c can obtain the serial number of the characteristic value 31 of fabricated product.In addition, channel number 1, channel number 2 and channel number 3 are distributed to measuring machine 6a, measuring machine 6b and measuring machine 6c respectively.
Promptly, in line production system 100 according to present embodiment, about the serial number of goods to be transmitted, the machine table 3a to 31 of the processing machine 5a of fabricated product and 5b, the goods that are fixed for processing and the measuring machine 6a to 6c that measures the characteristic value of fabricated product set up following relation.
Process and measure the goods of its characteristic value: OB 1, OB 2, OB 3...
Processing machine 5a, processing machine 5b:W 1, W 2
Machine table 3a to 3l:P 1, P 2, P 3..., P 12
Measuring machine 6a to 6c:M 1, M 2, M 3
Will be by processing machine W 1And W 2The goods OB of processing 1, OB 2, OB 3... serial number as follows.
W 1:OB 1,OB (x+1),OB (2x+1),...
W 2:OB 2,OB (x+2),OB (2x+2),...
In addition, by measuring machine M 1, M 2And M 3Measure the goods OB of its characteristic value 1, OB 2, OB 3... serial number as follows.
M 1:OB 1,OB (y+1),OB (2y+1),...
M 2:OB 2,OB (y+2),OB (2y+2),...
M 3:OB 3,OB (y+3),OB (2y+3),...
Similarly, will be by the fixing goods OB of machine table 3a to 3l 1, OB 2, OB 3... serial number as follows:
P 1:OB 1,OB (z+1),OB (2z+1),...
P 2:OB 2,OB (z+2),OB (2z+2),...
P 3:OB 3,OB (z+3),OB (2z+3),...
P 12:OB 12,OB (z+12),OB (2z+12),...
Therefore, for the predetermined quantity of measuring goods, when transverse axis represents to process and measure the transmission serial number of goods, during natural value that Z-axis is represented to obtain corresponding to the characteristic value 31 of each goods of second number by normalization, shown in Fig. 3 A to 3D, on measured characteristic value 31, add some points.
In addition, Fig. 3 A to 3D is the figure of relation of 31 of the characteristic values of the transmission serial number of expression processing and the goods of measuring its characteristic value and each goods.
Fig. 3 A represent to process and measure its characteristic value goods the transmission serial number and in normal condition, the relation that the characteristic value of each goods is 31.
In addition, Fig. 3 B represent to process and measure its characteristic value goods the transmission serial number and when not normal running processing machine 5a and 5b one, the relation that the characteristic value of each goods is 31.
In addition, Fig. 3 C represent to process and measure its characteristic value goods the transmission serial number and when any one of normal running measuring machine 6a to 6c not, the relation that the characteristic value of each goods is 31.
In addition, Fig. 3 D represent to process and measure its characteristic value goods the transmission serial number and when any one of not normal running machine table 3a to 3l, the relation that the characteristic value of each goods is 31.
For example, when all 100 goods of normal process, and when normally measuring its characteristic value 31, as shown in Figure 3A, 1 to 100 value of characterization value 31 is all the time in specialized range.In this case, about the relation of 31 of the characteristic values of the serial number of fabricated product and goods, not special survey its periodically.
On the other hand, when any one of not normal running processing machine 5a and 5b, shown in Fig. 3 B, the characteristic value 31 of measurement be not used for the specialized range of each.That is,,, generate the not characteristic value in specialized range 31 by two cycles about measuring the predetermined number of goods.
In addition, when any one of normal running measuring machine 6a to 6c not, measurement characteristics value 31 is not in the specialized range that is used for every.That is,,, generate the not characteristic value in specialized range 31 by three cycles about measuring the predetermined number of goods.
In addition, when any one of not normal running machine table 3a to 3l, shown in Fig. 3 D, measurement characteristics value 31 is not in the specialized range that is used for every ten.That is,,, generate the not characteristic value in specialized range 31 by 12 cycles about measuring the predetermined number of goods.
Similarly, when not normal process machine 5a and 5b any one, any one or the machine table 3a to 3l of measuring machine 6a to 6c any one the time, from processing with measure the serial number of goods and the relation of 31 of the characteristic values of each goods, constant cycle property appears.
In addition, in Fig. 3 A to 3D, measurement characteristics value 31 not be used for each, per two or per 11 specialized range, the periodicity of the characteristic value in specialized range is not limited thereto but generate not.
That is,, determine periodically by being included in the quantity of processing machine, machine table or measuring machine in the above-mentioned line production system 100.Then, processing machine, processing attitude or when measuring promptly number change periodically also change.
Similarly, according to the quantity of equipment,, maybe, can make periodically different with the quantity of the equipment adjusted such as being included in according to processing machine 5a in the line production system 100 of present embodiment and the quantity of 5b.
Wherein, with the periodicity detection method of describing by information detecting unit 16.
Particularly, by carrying out the arithmetical operation according to following equation (2) to (4), cycle information detecting unit 16 can detect the relation according to 31 of the characteristic values of the serial number of processing and measurement goods and each goods, discerns its periodicity.
That is, when the quantity of measuring goods is 100, and when checking that the measured characteristic value be not used for the specialized range of each when (by two cycles), according to the arithmetical operation of following equation (2).
∑((x(t)-x(t-1)) 2) (2)
X (t): the characteristic value of t goods
X (t-1): the characteristic value of (t-1) individual goods
In addition, t:1 t 100
In addition, when the quantity of measuring article is 100, and whether be not used for per two specialized range when (by three cycles), when the check measurement characteristic value according to the arithmetical operation of following equation (3).
∑((x(t)-x(t-2)) 2) (3)
X (t-2): the characteristic value of (t-2) individual goods
In addition, when the quantity of measuring goods is 100, and when the check measurement characteristic value whether not when being used for per 11 specialized range (by 12 cycles), according to the arithmetical operation of following equation (4).
∑((x(t)-x(t-11)) 2) (4)
X (t-11): the characteristic value of (t-11) individual goods
Wherein, as according to the result of equation (2) to the arithmetical operation of (4), figure 4 illustrates the characteristic value 31 of measuring goods for normal situation, characteristic value 31 not in the situation of the specialized range that is used for each, and characteristic value 31 is in the situation that is used for per two specialized range, and characteristic value 31 is not in the situation that is used for per 11 specialized range.
As shown in Figure 4, with under normal condition, the situation of carrying out according to equation (2) according to the situation of the arithmetical operation of equation (2) with on the characteristic value of the specialized range that be not used for each in execution on the characteristic value compares, and can understand that the latter has the value greater than the former.
Therefore, whether can judge by cycle information detecting unit 16 whether the result of the arithmetical operation of equation (2) characteristic value 31 occurs not in the periodicity of the specialized range that is used for each so that check according to the adjusting gear 7 of present embodiment.
In addition, with under normal condition, on characteristic value, carry out according to the situation of the arithmetical operation of equation (3) with or not the characteristic value that is used for per two specialized range, carry out according to the situation of the arithmetical operation of equation (3) and compare, can understand that the latter has than the former bigger value.
Therefore, can judge by cycle information detecting unit 16 according to the adjusting gear 7 of present embodiment, the result of the arithmetical operation of equation (3) equals still greater than predetermined threshold, so that check characteristic value 31 whether occurs not in the periodicity that is used for per two specialized range.
In addition, with under normal condition, on characteristic value, carry out according to the situation of the arithmetical operation of equation (4) with or not the characteristic value that is used for per 11 specialized range, carry out according to the situation of the arithmetical operation of equation (4) and compare, can understand that the latter has than the former bigger value.
Therefore, can judge the result of the arithmetical operation of the equation (4) that whether passes through cycle information detecting unit 16, so that check characteristic value 31 whether occurs not in the periodicity that is used for per 11 specialized range according to the adjusting gear 7 of present embodiment.
Therefore, cycle information detecting unit 16 will be sent to unusual estimation unit 17 to the result of the arithmetical operation of (4) at the equation on the measurement characteristics value 31 (2).
In line production system 100, for example,, may omit goods if import goods continuously from goods inlet 1 according to present embodiment.Yet, in this case and since cycle information detecting unit 16 be configured to carry out be used for considerable characteristic value 31 equation (2) to (4), about the characteristic value 31 that will stand arithmetical operation, roughly keep periodically.
Therefore,, in this way, in the serial number of fabricated product, occur omitting, can obtain value near value shown in Figure 4 even when arithmetical operation by cycle information detecting unit 16.
Unusual estimation unit 17 estimates to be used for the reason of abnormality based on following information.Information is to be used for the rejection rate of all measurement characteristics values of receiving from rejection rate arithmetic element 14 and at the rejection rate of each characteristic value 31 of being measured by each measuring machine 6a to 6c.In addition, information is the histogrammic information that expression receives from histogram feature detecting unit 16.In addition, information is the periodic information that expression receives from cycle information detecting unit 16.
Therefore, unusual estimation unit 17 information that expression is used for operator's indication is sent to indication output 19 or transmits the information that according to the estimation that is used for abnormality former thereby expression is used for the adjustment indication of adjusting gear 7.
19 operations of indication output unit are according to the line production system of the embodiment of the invention, so that operating personnel are exported in the adjustment indication of machine table or measuring machine 6a to 6c.Adjusting gear 7 according to present embodiment has the display device (not shown), and indication output unit 19 will be sent to display device from the adjustment indication information that unusual estimation unit 17 receives and indicated number equipment shows the adjustment indication information.
Similarly, adjust indication, can indicate member to be adjusted to operating personnel by display device is shown.In addition, the information that operating personnel's adjustment is indicated is not limited thereto.For example, when each operating personnel can have portable terminal, and portable terminal can be sent to portable terminal from indication output unit 19 with adjusting indication can be connected to adjusting gear 7 by ground the time.In addition, when the adjusting gear 7 according to present embodiment has printing device, can output to printing device, then, print on the paper and inform operating personnel so that will adjust indication with adjusting indication.
If any one of unusual estimation unit 17 estimation processing machine 5a and 5b has abnormal cause, adjustment unit 18 is adjusted the setting value of the processing machine with abnormal cause.Adjustment unit 18 indicative of settings unit 22 change the setting value of the processing machine with abnormal cause.
In addition, below, will describe by adjustment unit 18, the adjustment of any one setting value of processing machine 5a and 5b is handled.
Setup unit 22 changes the setting value of processing machine 5a or processing machine 5b according to the indication from adjustment unit 18.
State changes detecting unit 20 and receives indication and indicate total unit 18 to be aggregated in the characteristic value 31 of the goods of processing after any one setting value that changes processing machine 5a and 5b from adjustment unit 18.In addition, state changes the estimation processing that the unusual estimation unit 17 of detecting unit 20 indications stops abnormal cause.
Wherein, in line production system 100 according to present embodiment, below, will describe from the abnormal cause of the characteristic value 31 of fabricated product measurement with reference to figure 5.In addition, Fig. 5 is the expression abnormal cause that is used for each measuring machine 6a to 6c, when producing abnormal cause, the phenomenon that characteristic value is introduced, and the figure that prevents the countermeasure of abnormal cause.
As mentioned above, have processing machine 5a and 5b, machine table 3a to 3l according to the line production system 100 of present embodiment, and measuring machine 6a to 6c.For this reason, when any one of the single member of normal running not, the characteristic value 31 of measurement becomes unusually.
About the reason when not normal running processing machine 5a or the processing machine 5b, can example go out the mechanical error of processing machine 5a or processing machine, and the wearing and tearing that cause by the processing of processing machine 5a or processing machine 5b.
In addition, about the reason when any one of not normal running machine table 3a to 3l, example go out to unclamp with act on goods be installed in the member among the machine table 3a to 3l anchor clamps, connect or the like to the fragment of the installation site of goods.
In addition,, can example go out any one measuring error of measuring machine 6a to 6c, and when corresponding measuring machine measurement characteristics value 31, be used for fixing the offset of the anchor clamps of goods about the reason when any one of normal running measuring machine 6a to 6c not.
Therefore, when in any one of not normal running processing machine 5a and 5b, any one of machine table 3a to 31, or under any one situation of measuring machine 6a to 6c, during fabricated product, observe the following phenomenon from the characteristic value 31 that fabricated product is measured.
That is, when any one of not two processing machine 5a of normal running and 5b, about processing with measure the serial number of goods and the relation of 31 of the characteristic values of each goods, characteristic value 31 becomes each unusual.That is, make value that the arithmetical operation by equation (2) obtains greater than predetermined threshold.
In addition, the feature of characteristic value 31 according to all characteristic values 31, in the histogram that adds up to unit 13 to create, two peak values occur, shown in Fig. 2 B during about any one of not two processing machine 5a of normal running and 5b.
For this reason, when two peak values in histogram, occurring, if the result of arithmetical operation who makes the equation (2) by cycle information detecting unit 16, can judge not normal running processing machine 5a and 5b any one greater than predetermined threshold.
In addition, when any one of not normal running machine table 3a to 3l, the rejection rate that is used to measure all characteristic values 31 of goods becomes predetermined threshold.
In addition, when any one of not normal running machine table 3a to 3l, characteristic value 31 become to per 11 unusual.That is, make value that the result of the arithmetical operation by equation (4) obtains greater than predetermined threshold.
In addition, when any one of normal running measuring machine 6a to 6c not, compare, comprise a large amount of abnormal characteristic values from the characteristic value 31 of any one acquisition of measuring machine 6a to 6c with other measuring machines.That is, as shown in Figure 7, make by among the measuring machine 6a to 6c, the rejection rate with characteristic value 31 that the processing machine of dedicated tunnel number measures is greater than among the measuring machine 6a to 6c, has the rejection rate of the characteristic value that the measuring machine of other channel numbers measures.
In addition, Fig. 7 is the histogrammic figure of expression according to the characteristic value 31 of each measurement of passing through measuring machine 6a to 6c.As shown in Figure 7, when producing among the measuring machine 6a with channel number 1 when unusual, the distribution of the characteristic value of being measured by measuring machine 6a appears in the scope except that the specialized range alpha-beta.In addition, in the position of the intermediate value that significantly departs from specialized range peak value appears.
In addition, when any one of normal running measuring machine 6a to 6c not, about the relation of 31 of the characteristic values of the serial number of measuring goods and each goods, 31 pairs of characteristic values become unusual every two.That is, make value that the result of arithmetical operation that will be by equation (3) obtains greater than predetermined threshold.
When any one of 12 machine table is unusual, can make by among the measuring machine 6a to 6c, rejection rate with characteristic value 31 that the measuring machine of dedicated tunnel number measures is greater than by among the measuring machine 6a to 6c, has the rejection rate of the characteristic value 31 that the measuring machine of other channel numbers measures.
In this case, yet, have from the characteristic value 31 that the measuring machine of the dedicated tunnel of measuring machine 6a to 6c number is measured, confirm unusual probability basically 25%.
Therefore, the structure that further comprises following condition can be provided in case can with any one unusual situation of 12 machine table 3a to 3l with in any one of measuring machine 6a to 6c, produce unusual situation and make a distinction.Promptly, rejection rate with characteristic value 31 of measuring from the measuring machine of the dedicated tunnel of measuring machine 6a to 6c number is greater than the waste product with characteristic value of measuring from the measuring machine of other channel numbers of measuring machine 6a to 6c, and rejection rate is predetermined threshold (this value is greater than 25%).
In addition, can be each arithmetical operation, the predetermined threshold with respect to the value of result's acquisition of the arithmetical operation by separate equation formula (2) and (4) is provided separately, or can provide jointly.
For example, when the predetermined threshold that public value is provided as with respect to the value that obtains to the result of the arithmetical operation of (4) by separate equation formula (2), predetermined threshold greater than under normal condition, the separate equation formula (2) carried out on characteristic value is to the result of the arithmetical operation of (4).With respect to the relation in the candidate value to be adjusted, that is, the relation among processing machine 5a and 5b, machine table 3a to 31 and measuring machine 6a and the 6b suitably is provided with public value.
In addition, when the predetermined threshold that provides individually with respect to the value that obtains to the result of the arithmetical operation of (4) by equation (2), determine that threshold value is as follows.
Promptly, can be by when the normal condition, when the characteristic value 31 of goods is unusual to each, when 31 pairs of the characteristic values of goods per two when unusual, and when the characteristic value of goods to per 11 when unusual, by the result that the arithmetical operation of carrying out equation (2) obtains, the threshold value of the value that obtains with respect to the result by the arithmetical operation of equation (2) is set.In addition, as mentioned above, for example, the result of arithmetical operation as shown in Figure 4.For this reason,, threshold value is arranged to be equal to or less than " 160733 " and is to become when unusual every one, " 214833 " of the scope that obtains according to the result of arithmetical operation when 31 pairs of characteristic values with reference to the result of the arithmetical operation shown in the figure 4.
In addition, can be by when the normal condition, when the characteristic value 31 of goods is unusual to each, when 31 pairs of the characteristic values of goods per two when unusual, and when the characteristic value of goods to per 11 when unusual, by the result that the arithmetical operation of carrying out equation (3) obtains, the threshold value of the value that obtains with respect to the result by the arithmetical operation of equation (3) is set.In addition, as mentioned above, for example, the result of arithmetical operation as shown in Figure 4.For this reason, with reference to the result of the arithmetical operation shown in the figure 4, it is to become when unusual when per two of 31 pairs of characteristic values that threshold value is arranged to be equal to or less than, " 165419 " of the scope that obtains according to the result of arithmetical operation.
In addition, can be by when the normal condition, when the characteristic value 31 of goods is unusual to each, when 31 pairs of the characteristic values of goods per two when unusual, and when the characteristic value of goods to per 11 when unusual, by the result that the arithmetical operation of carrying out equation (4) obtains, the threshold value of the value that obtains with respect to the result by the arithmetical operation of equation (4) is set.In addition, as mentioned above, for example, the result of arithmetical operation as shown in Figure 4.For this reason,, be arranged to threshold value greater than " 8467 " and be to become when unusual, " 37789 " of the scope that obtains according to the result of arithmetical operation when per 11 of 31 pairs of characteristic values with reference to the result of the arithmetical operation shown in the figure 4.
In addition, for example as described below, the predetermined threshold 31 with respect to the rejection rate that is used for all characteristic values is set.That is, in candidate value to be adjusted, machine table 3a to 3l has minimum rejection rate.Therefore, about the threshold value of rejection rate, when measuring the characteristic value 31 of 100 goods, and when any one of not normal running machine table 3a to 3l,, in the characteristic value of measuring 31, confirm unusual with the ratio of per ten secondaries 1.For this reason, rejection rate becomes about 8%.Therefore, the threshold value of rejection rate is arranged to 8%.
In addition, in fact,, preferably predetermined threshold is arranged to have the variation of considering to measure measuring error or measurement characteristics value, the minute widths of the scope of possible threshold value owing to generate the measuring error of measuring machine or the variation in the characteristic value.
In addition, in adjusting gear 7, the information of relevant threshold value is stored in the information memory cell 12 in advance, as the threshold information (not shown) according to present embodiment.
When in line production system 100, when specifying member to be adjusted, carry out following countermeasure by use abnormality detection condition according to present embodiment.
For example,, confirm when unusual, change any one setting value of processing machine 5a and 5b when in any one of processing machine 5a and 5b.
On the other hand, when in any one of machine table 3a to 3l or measuring machine 6a to 6C, confirming when unusual, the indication operating personnel fixedly machine table 3a to 3l anchor clamps or clean machine table 3a to 3l or indicate operating personnel to adjust measuring machine 6a to 6c, adjust the contact of the anchor clamps of measuring machine 6a to 6c, and clean anchor clamps.
Then, will describe by using above-mentioned abnormality detection condition, how to estimate the reason of abnormality with reference to figure 6.
(estimation of abnormality reason is handled)
Then, when identifying unit 21 is judged when having not the characteristic value 31 in specialized range, will be with describing by the processing of the abnormality reason of carrying out according to the adjusting gear 7 of present embodiment.
Wherein, the rejection rate of supposing all measurement characteristics values is 5%, and the rejection rate of the characteristic value of being measured by each measuring machine 6a to 6c 31 is respectively 10%, and is 10000 with respect to the threshold value of the setting as a result of the arithmetical operation of equation (2) to (4).In addition, threshold value is stored in information memory cell 12 (not shown) in advance.
In addition, receive histogram distribution characteristic (peak value) from histogram feature detecting unit 15, receive the rejection rate of the characteristic value of measuring by each measuring machine 6a to 6c 31 and the rejection rate of all characteristic values from rejection rate arithmetical unit 14, and from cycle information detecting unit 16 receiving cycle information.
At first, unusual estimation unit 17 is removed the setting value (step S11) (being called S11 hereinafter) of warning notice before the estimation of execute exception reason is handled.In addition, warning notice is to be used for representing to carry out estimating to handle the sign that also is stored in advance in information memory cell 12 (not shown).
In addition, whether unusual for judging any one of machine table 3a to 3l, whether any one of processing machine 5a and 5b be unusual, or whether any one of measuring machine 6a to 6c be unusual, and warning notice is provided.
Therefore, when also the estimation of execute exception reason is not handled, in information memory cell 12, warning notice needn't be set.For this reason, before the estimation of execute exception reason was handled, unusual estimation unit 17 was removed the setting value of warning notice.Particularly, when in information memory cell 12, when being set to warning notice, unusual estimation unit 17 signs are set to " 0 " with " 1 ".
Then, unusual estimation unit 17 compares the rejection rate of the characteristic value 31 of each measuring machine 6a to 6c with the rejection rate that receives from rejection rate arithmetical unit 14.Then, unusual estimation unit 17 judges whether there is the rejection rate that is equal to or greater than predetermined threshold (rejection rate 5%) by the rejection rate of the characteristic value 31 relevant with the channel number of each measuring machine 6a to 6c.
Wherein, about result of determination, when only a rejection rate was equal to or greater than predetermined threshold (being "Yes" among the S12), unusual estimation unit 17 was provided with warning notice (S13).That is, whether unusual according to any one of measuring machine 6a to 6c, unusual estimation unit 17 is provided with 1 sign by way of caution in information memory cell 1.
On the other hand, be under the situation of "No" in step S12, judge whether the rejection rate that is used for all measurement characteristics values is equal to or greater than predetermined threshold (8%) (S21).
If finish the setting of warning notice, unusual estimation unit 17 judges based on the result of the arithmetical operation of the equation (3) of cycle information detecting unit 16 whether the result of arithmetical operation is equal to or greater than predetermined threshold (1000).Wherein, when any one of measuring machine 6a to 6c was unusual, as shown in Figure 4, the result of the arithmetical operation of equation (3) was " 165419 ".For this reason, the result of arithmetical operation is equal to or greater than the threshold value " 10000 " that sets in advance.
Therefore, as result of determination, when the result who judges arithmetical operation was equal to or greater than predetermined threshold (being "Yes" among the S14), any one of unusual estimation unit 17 estimation measuring machine 6a to 6c was in the abnormality.
On the other hand, under the situation that is judged to be "No" of step S14, judge whether the rejection rate of all measurement characteristics values 31 is equal to or greater than predetermined threshold (8%) (S21).
Wherein, when any one of measuring machine 6a to 6c was in the abnormality, at step S15, for any one of notice measuring machine 6a to 6c is in purpose in the abnormality, unusual estimation unit 17 was to the information of indication output unit 19 these notices of output expression.
In this way, when any one of measuring machine 6a to 6c was in abnormality, unusual estimation unit 17 can be specified measuring machine to be adjusted and be notified the operating personnel of measuring machine to be adjusted.
Then, be to be under the situation of "No" among "No" or the step S14 in step S12, unusual estimation unit 17 judges whether the rejection rate that is used for all measurement characteristics values is predetermined threshold (S21).In addition, when any one of machine table 3a to 3l was in abnormality, the rejection rate that is used for all characteristic values 31 became 8.3% or higher, is equal to or greater than predetermined threshold (8%) thus.
According to judged result, when the rejection rate that is used for all characteristic values 31 is equal to or greater than predetermined threshold (10000) (S21 "Yes"), unusual estimation unit 17 is provided with warning notice (S22).That is, whether all unusual estimation unit 17 establishes set according to any one judgment processing in abnormality of machine table 3a to 3l in information memory cell, indicate by way of caution.
On the other hand, be under the situation of "No" at step S21, judge at the histogram that is used for all characteristic values 31 two peak values or more whether occur.
When in step S22 warning notice being set, unusual estimation unit 17 judges whether the result of the arithmetical operation of equation (4) is equal to or greater than threshold value (S23).As judged result, when the result of the arithmetical operation of judgement equation (4) is equal to or greater than threshold value ("Yes" among the S23), any one of unusual estimation unit 17 estimation machine table 3a to 3l is in (S24) in the abnormality.That is, when any one of machine table 3a to 3L was in abnormality, as shown in Figure 4, the result of the arithmetic results of equation (4) became " 37789 ", therefore, is equal to or greater than threshold value (10000).
Therefore, be under the situation of "Yes" in step S23, estimate that unusually 17 have any one that estimate machine table 3a to 3l unusual.In this case, for any one of notifying operation personnel machine table 3a to 3l is in the purpose of abnormality, the notice of the purpose of unusual estimation unit 17 output expression abnormality.
On the other hand, be under the situation of "No" at step S23, the processing shown in the unusual estimation unit 17 execution in step S31 promptly, is judged at the histogram that is used for all measurement characteristics values 31, whether has two peak values or more.
In this way, when any one of machine table 3a to 3l was in abnormality, unusual estimation unit 17 can be appointed as machine table equipment to be adjusted and the specified machine table of notifying operation personnel.
Then, be under the situation of "No" at step S21 or step S23 is under the situation of "No", unusual estimation unit 17 judges whether the histogrammic peak value based on all measurement characteristics values 31 establishments is two or more, or one (S31).
According to the judged result of step S31, when unusual estimation unit 17 is judged histogrammic peak value for two or more (step S31 is a "Yes"), warning notice is set.That is, whether be in the judged result of abnormality according to any one of processing machine 5a and 5b, unusual estimation unit 17 is established set and is indicated by way of caution in information memory cell.
On the other hand, in step S31, judge that histogrammic peak value is 1, unusual estimation unit 17 confirms exist/not exist the warning notice (S41) of record in the information memory cell 12.
When in step 32 warning notice being set, unusual estimation unit 17 judges whether the result of the arithmetical operation of equation (2) is equal to or greater than threshold value (10000) (S33).Therefore, the judged result in step S33 is under the situation of "Yes", and any one of unusual estimation unit 17 estimation processing machine 5a and 5b is in abnormality (S34).That is, when any one of processing machine 5a and 5b was in abnormality, as shown in Figure 4, the result of the arithmetical operation of equation (2) became " 37789 ", therefore, is equal to or greater than threshold value " 10000 ".
On the other hand, be under the situation of "No" at step S33, process proceeds to step S41.That is, unusual estimation unit 17 is carried out and is used to judge existence/the do not exist processing of warning notice.
Therefore, be under the situation of "Yes" at step S33, unusual estimation unit 17 can estimate that any one of processing machine 5a and 5b is unusual.In this case, any one of unusual estimation unit 17 notice adjustment unit 18 processing machine 5a and 5b is in the purpose of abnormality.Therefore, unusual estimation unit 17 will be sent to adjustment unit based on the histogrammic information of all measurement characteristics values 31 together with this notice.
In this way, when any one of processing machine 5a and 5b is in abnormality, unusual estimation unit 17 can specify processing machine 5a and 5b any one inform adjustment unit 18 as equipment to be adjusted and with the processing machine of appointment.
In step S31, when judging that histogrammic peak value is 1, or when the result of the arithmetical operation of the equation among the determining step S33 (2) when being lower than threshold value, estimation unit 17 judges whether to be provided with warning notice (S41) unusually.That is, according to whether warning notice being set, unusual estimation unit 17 can be understood the estimation of whether carrying out any one abnormality that is used for measuring machine 6a to 6c, machine table 3a to 3l and processing machine 5a and 5b and handle.
Wherein, when warning notice is set, can understand, be equal to or greater than threshold value corresponding to any one rejection rate of the characteristic value 31 of each channel number of measuring machine 6a to 6c or the rejection rate that is used for all characteristic values 31 about at least one measurement characteristics value 31.This phenomenon is illustrated in any one of the equipment that is included in the line production system 100, produces abnormality, as mentioned above.
Therefore, be under the situation of "Yes" in step S41, unusual estimation unit 17 will represent to produce the warning notice indication output unit of abnormality.By this notice, which unit exception operating personnel can confirm.
On the other hand, (be not "No" among the S41) when warning notice is arranged to 1, unusual estimation unit 17 considers that diagnosis can not (S43) and this process of end.
As mentioned above, can specify equipment to be adjusted according to the adjusting gear of present embodiment, and can indicate the setting value of informing designated equipment to be adjusted or adjusting equipment to be adjusted with appointment abnormality.
(adjustment of setting value is handled)
Then, when the notice of the purpose of any one (being in abnormality) that receive normal running processing machine 5a not or processing machine 5b from unusual estimation unit 17, will handle with reference to the adjustment that figure 8 and 9 describes the setting value of being carried out by adjustment unit 18.
In addition, Fig. 8 is in the adjusting gear 7 of example explanation according to present embodiment, the figure of the example that the adjustment of setting value is handled.In addition, Fig. 9 is the process flow diagram that expression is handled according to the search of the corrected value in the adjusting gear of present embodiment.
When any one of not normal running processing machine 5a and processing machine 5b, as if in based on the histogram by the characteristic value 31 of the goods of any one processing of processing machine 5a and processing machine 5b, peak value portion departs from the intermediate value of specialized range alpha-beta.For this reason, when any one of not normal running processing machine 5a and processing machine 5b, in histogram, produce two peak value (A based on all measurement characteristics values 31 1And A 2).
Wherein, in the adjusting gear 7 according to present embodiment, peak A will appear in adjustment unit 18 1Part value and peak A appears 2The value of part compare with value as the part of the intermediate value M of specialized range alpha-beta.Then, change the setting value of processing machine so that make other peak values near near a peak value of the value of the part of intermediate value M.
That is, normal running is by the goods of another processing of processing machine 5a and processing machine 5b.That is, in based on the histogrammic distribution by the characteristic value 31 of the goods of another processing of processing machine 5a and 5b, the histogram that occurs peak value in the part near intermediate value M can be considered as the histogram based on the characteristic value 31 of the goods that satisfy definite quality.
Therefore, change the setting value of processing machine so that make other peak values from peak A 1And peak A 2Approximate near the peak value of the intermediate value M of specialized range alpha-beta.In this way, can be near histogram based on the characteristic value 31 of the goods that satisfy definite quality.
Therefore, in histogrammic example shown in Figure 8, because peak A 2The value of the part that occurs be positioned at intermediate value M near, can change the setting value of processing machine 5a or processing machine 5b and peak A occur so that make 1The value of part bigger.
In addition, in contrast, work as peak A 1When appearing near intermediate value M, the setting value that changes processing machine 5a or processing machine 5b peak A occurs so that make 2The value of part bigger.
On histogram shown in Figure 8, about peak A 1And peak A 2, can not understand the characteristic value 31 of peak value reflection by the mach goods of any processing.
Therefore, in adjustment unit 18, particularly, change any one setting value of processing machine 5a and processing machine 5b so that increase the characteristic value 31 of fabricated product according to present embodiment.Subsequently, according to changing the result, the setting value of another of change processing machine.
For example, as shown in Figure 8, so that when increasing characteristic value 31, suppose from histogrammic peak A based on measured characteristic value 31 when the setting value that at first changes processing machine 5a 1And peak A 2, peak A 2On move on to the position of representing with s.That is, suppose higher limit β in the distributed expansion overshoot scope of the characteristic value of representing with histogram 31.
In this case, can understand that the variation of the distribution of characteristic value 31 is expanded significantly, and can not fine execution adjustment.Similarly, in the time can not carrying out adjustment, the setting value of processing machine 5a turns back to the initial value with respect to the device initial value of storing in advance 32 once more in information memory cell 12.Then, with respect to processing machine 5a, change the setting value of processing machine 5b.Therefore, as shown in Figure 8, suppose histogrammic peak A 1Value on move on to the value of the part of representing with T.
That is, reach the value of peak A 1 of the value of T by change, the sum of the peak value in the histogram becomes 1, and peak value appear at intermediate value M in the specialized range alpha-beta of characteristic value 31 near.In addition, all characteristic values 31 drop in the specialized range alpha-beta.
When the histogram based on the characteristic value of measuring in this state 31 occurs, can judge by changing the setting value of processing machine 5b, carry out the adjustment of processing machine 5b well.
In this way, in line production system 100,, can suitably carry out the adjustment of processing machine 5a or processing machine 5b by change the value that peak value occurs in histogram according to present embodiment.Hereinafter, will the flow process of the adjustment processing of any one setting value of adjusting processing machine 5a and processing machine 5b be described with reference to figure 9.
At first, when receiving the purpose notice of not normal running processing machine 5a and processing machine 5b any one (being in abnormality), the unusual estimation unit 17 of adjusting gear 18 indications stops the estimation of abnormal cause and handles (S541).Similarly, adjustment unit 18 is during the adjustment of setting value is handled, and the estimation that stops the abnormal cause of unusual estimation unit 17 is handled.
Then, adjustment unit 18 is determined the policy (S52) of the setting value change of processing machine 5a or processing machine 5b based on the histogrammic information and the notice that transmit from unusual estimation unit 17.Being used for policy that setting value changes determines to change the setting value of processing machine 5a or processing machine 5b so that increase or reduce characteristic value 31 by the goods of any one processing of processing machine 5a and processing machine 5b.
As mentioned above, when in two parts, peak value occurring,, increase the value that still reduces the part that another peak value occurs, carry out and determine according to part based near the peak value of the intermediate value M that appears at the specialized range alpha-beta.
In the present embodiment, about determining, suppose any one setting value of adjustment unit 18 definite processing machine 5a of change and processing machine 5b, so that increase the characteristic value 31 of fabricated product.
Then, adjustment unit 18 at first changes the setting value of processing machine 5a so that increase the characteristic value of measuring by by the goods of processing machine 5a processing 31 (S53).In addition, the change amount of setting value is an appropriate value, and can be the setting value that increases at least by the characteristic value of the mach goods of processing of the setting value with change.That is, in the present embodiment, therefore, be configured to by repeating to change setting value, histogrammic shape is near the histogram based on the characteristic value of the fabricated product that satisfies definite quality.
Wherein, if change the setting value of processing machine 5a, after change, the characteristic value 31 that obtains is different from the characteristic value 31 before changing.Then, adjustment unit 18 notify status change the state change (S54) of the setting value of detecting unit 20 expressions change processing machine 5a.According to this notice, state changes detecting unit 20 indications and adds up to unit 13 to add up to characteristic value 31 once more.Then, according to the indication that changes detecting unit 20 from state, after total unit 13 is aggregated in the characteristic value that changes processing machine 5a, the characteristic value 31 of fabricated product.
In addition, about adding up to the indication of unit 13, after any one the measurement setting value change by measuring machine 6a to 6c, 20 distribution of state change detecting unit and indication are by the time of processing machine 5a fabricated product.
That is, in line production system 100, be configured to goods are sent to measuring machine 6a to 6c from processing machine 5a through constant speed according to present embodiment.For this reason, fabricated product is sent to time till the measuring machine 6a to 6c, after understanding setting value and changing, by the Measuring Time of the characteristic value 31 of the goods of processing machine 5a processing by calculating.
In addition, related with Measuring Time as mentioned above, will be stored in the information memory cell 12 by the characteristic value 31 of any one measurement of measuring machine 6a to 6c.For this reason, add up to unit 13 can add up to by characteristic value with the mach goods of processing that change setting value.
In this way, add up to unit 13 to add up to, create histogram by characteristic value 31 and based on characteristic value 31 with the mach goods of processing that change setting value.Therefore, add up to unit notice adjustment unit 18 to create histogrammic information.
Adjustment unit 18 judges based on the information from adding up to unit 13 to receive whether the quantity of peak value in the histogram becomes 1 (S55).That is, adjustment unit 18 judges whether to be increased in the frequency of characteristic value of the part near intermediate value of specialized range alpha-beta and the frequency that reduces the characteristic value in the part before and after that part gradually.
In step S55, when adjustment unit 18 judged that peak value becomes 1 (being "Yes" among the S55), the adjustment processing of setting value finished.
On the other hand, be under the situation of "No" in step S55, before changing with the setting value of processing machine 5a, the distance between two peak values is compared, and judges distance between two peak values that occur in the histogram of the histogram information that is received whether diminish (S56).In addition, peak separation from being calculated as peak A can be appearred 1Part value and peak A appears 2The value of part between the absolute value of difference.
That is, when the setting value of carrying out processing machine 5a changed, although do not specifically illustrate in Fig. 1, adjustment unit 18 will be in the histogram of the characteristic value 31 before changing based on setting value, and the value that the part of peak value occurs is stored in the information memory cell 12.Then, the distance between the value of the part of each peak value that adjustment unit 18 will be stored in information memory cell 12 is with after the setting value change of processing machine 5a, and the distance between the value of the part of each peak value in the histogram that is received compares.
Compare about this, when adjustment unit 18 is judged peak separations from do not diminish (being "Yes" among the S56), the setting value change that process turns back to step S53 and carries out processing machine 5a once more.Then, repeating step S53 to S56 becomes till 1 up to the quantity of the part that peak value occurs.
On the other hand, so that increase characteristic value by the goods of processing machine 5a processing, in based on the histogram by the characteristic value of the goods of processing machine 5a or processing machine 5b processing, peak separation is from not diminishing when the setting value that changes processing machine 5a.That is, be under the "No" condition at step S56, the state that adjustment unit 18 notify status change the setting value of detecting unit 20 expressions change processing machine 5a changes (S57).
Even changing, state described herein is meant that setting value turns back to initial set value because when the setting value that changes processing machine 5a, the result of measured characteristic value is still dissatisfied.Then, adjustment unit 18 reference unit initial values 32 turn back to initial set value (S58) with the change setting value of processing machine 5a.
Similarly, if the setting value of processing machine 5a turns back to initial value, adjustment unit 18 changes the setting value of processing machine 5b, so that increase the characteristic value of being measured by the goods of processing machine 5b processing (S59).Step 60 subsequently is identical with the step of carrying out with respect to processing machine 5a to S62, and with the descriptions thereof are omitted.
Yet in step S62, even when the setting value that changes processing machine 5b, peak separation is (step S62 is a "No") when also not becoming, and indicates this indication output unit 19 notification alert.
That is, even change the setting value of processing machine 5a and processing machine 5b, based on the histogram of measurement characteristics value near histogram based on the characteristic value of the fabricated product that satisfies definite quality.For this reason, judge that the abnormal cause of measurement characteristics value is not based on the mechanical error of processing machine 5a or processing machine 5b.
Therefore, because this indication output unit 19 notification alert of adjustment unit 18 indication, operating personnel can understand that the abnormal cause of measurement characteristics value is that mechanical error by processing machine 5a or processing machine 5b causes.
Therefore, operating personnel can check other reasons effectively, for example the wearing and tearing in any one of processing machine 5a and processing machine 5b.
Similarly, when the characteristic value of being measured by fabricated product is not in specialized range, can specify abnormal cause based on characteristic value according to the adjusting gear 7 of present embodiment.Promptly, based on two cycles, three cycles or ten one-periods, the not characteristic value in specialized range occurs, adjusting gear 7 can be specified any one of processing machine 5a and 5b, any one of measuring machine 6a to 6c or any one of machine table 3a to 3l effectively, as abnormal cause.
Especially, adjusting gear 7 can indicate abnormal cause when fabricated product.
In addition, adjusting gear 7 can the notifying operation personnel abnormal cause that indicates of indication by indication output unit 19.
In addition, when any one of processing machine 5a and 5b was appointed as abnormal cause, adjustment unit 18 can adjust the setting value of processing machine 5a or 5b so that the characteristic value that obtains to measure from the fabricated product that satisfies definite quality.
In addition, in line production system 100, provide machine table 3a to 3l, processing machine 5a and 5b and measuring machine 6a to 6c, but device type is not limited thereto according to present embodiment.For example, can provide unit mahine.Best, according to the type of goods to be processed, suitably select the type of these equipment.
In addition, in line production system 100, can provide 12 machine table 3a to 3l, two processing machine 5a and 5b and three measuring machine 6a to 6c, but the quantity of equipment is not limited thereto according to present embodiment.For example, if the quantity of the quantity of the quantity of machine table 3a to 3l, processing machine 5a and 5b and measuring machine 6a to 6c differs from one another, can provide any a plurality of equipment.According to the type of goods to be processed, quantity of goods or the like, determine the quantity of these equipment.
In addition, in the estimation of abnormal cause is handled, by the unusual existence of the unusual existence of measuring machine/do not exist, machine table/do not exist, and the unusual existence of processing machine/non-existent serial number, carry out and estimate to handle, but estimate that the serial number of handling is not limited thereto.
For example, can be in order, carry out and estimate to handle from having equipment that inconsistency appears in high frequency.In addition, the route that can occur according to the inconsistency of each equipment or when generation was inconsistent in each equipment, the change route of characteristic value was determined serial number.
In addition, the route that inconsistency occurs is the path that anchor clamps that route, machine table or fragment that the measuring error of for example measuring machine or the like occurs connect unclamp appearance.
In addition,, for example, when producing the measuring error of measuring machine, change characteristic value gradually, simultaneously, when producing anchor clamps that machine table or fragment connect and unclamp, at short notice, change characteristic value in a way significantly about the route of the change of characteristic value.
Any process that can be used in addition, production and processing according to the line production system 100 of present embodiment.Therefore, the fabricated product of measuring its characteristic value by measuring machine 6a to 6c can be finished product or the goods during production and processing is made.
In addition, as mentioned above, for detecting the not periodicity of the characteristic value in specialized range 31, cycle information detecting unit 16 user's formulas (2) are to (4), but the algorithmic approach of cycle information detecting unit 16 is not limited thereto.For example, can use FFT.
For example, cycle information detecting unit 16 keeps processing and measures the transmission serial number of goods of its characteristic value and each that is used for goods transmits relation (Fig. 3 B to 3D) between the characteristic value of serial number, as time series data.That is, the transmission serial number of the goods shown in each the transverse axis of Fig. 3 B to 3D is remained value on the time shaft.
Then, cycle information detecting unit 16 is configured on time series data, carries out arithmetical operation, and detect the not cycle of the appearance of the characteristic value in specialized range by FFT (fast fourier transform).
That is, the power spectrum that obtains by the result who uses according to the arithmetical operation of FFT can proof cycle, with coming to the same thing of the arithmetical operation of equation (2) to (4).
For example, as mentioned above, the relation between the serial number of the goods that transmitted by travelling belt 8 and the characteristic value measured by each goods is set to time series data, and the scope of the serial number of from 0 to 100 shown in the transverse axis is considered as one second.With reference to Fig. 3 B and 3C with time series data, for example shown in Fig. 3 B, can will the frequency that 50 characteristic values in the specialized range of 0 to 100 scope remain 50Hz appear not.
For this reason, according to the result of the FFT on the time series data, when intensive wavelength appearred in the position at 50Hz, characteristic value can not be used for the specialized range of each.In this case, can estimate in any one of processing machine 5a and processing machine 5b and produce abnormality.
Similarly, according to Fig. 3 C, shown in Fig. 3 C, the situation of 33 characteristic values of value that 0 and 100 specialized range occurs exceeding can be remained the frequency of 33Hz.
For this reason, according on time series data, the result of the arithmetical operation of FFT, when intensive wavelength appearred in the position at 33Hz, characteristic value may not be used for per two specialized range.In this case, can estimate in any one of measuring machine 6a to 6c, to produce unusual.
In addition, similarly,, shown in Fig. 3 D, the situation of 8 characteristic values of value that 0 and 100 specialized range occurs exceeding can be remained the frequency of 8Hz with reference to figure 3D.
For this reason, according on time series data, the result of the arithmetical operation of FFT, when intensive wavelength appearred in the position of 8Hz, characteristic value may not be used for per 11 specialized range.In this case, can estimate in any one of machine table 3a to 3l, to produce unusual.
Similarly, when cycle information detecting unit 24 detect characteristic value appears and cycle not in the specialized range of FFT arithmetical operation, compare with equation (2) to the arithmetical operation of (4), can pass through degree of precision, detect periodically.
Yet, shown in equation (2) to (4), can obtain and be used for each, be used for per two and the summation of size that is used for the difference of per 11 characteristic value 31.In this case, compare with the situation of using FFT, the summation of arithmetical operation diminishes, and realizes high speed processing.
In addition, in above-mentioned adjusting gear 7, the structure that can estimate as the equipment of equipment to be adjusted has been described.Best, provide the adjustment result who shows as being appointed as the equipment of equipment to be adjusted, the structure of the change state of the variation of the characteristic value of acquisition.
For example, suppose that one of machine table 3a to 3l, processing machine 5a and any one of 5b and any one of measuring machine 6a to 6c occur unusual.In this case, according on time series data, the result of the arithmetical operation by FFT obtains power spectrum as shown in figure 10.That is, at the frequency location place of 8Hz, 33Hz or 50Hz, it is big that the amplitude of wavelength becomes.
Yet when any one of machine table 3a to 3l was unusual, when any one of measuring machine 6a to 6c is unusual, or when any one of processing machine 5a and 5b is unusual, the characteristic value that obtains from goods is the degree difference specialized range not.That is,, be created in the interior characteristic value of specialized range and the variation of the difference between the measurement characteristics value according to equipment as abnormal cause.For this reason, as shown in figure 11, the amplitude at 8Hz, 33Hz or 50Hz place varies in size.
In addition, according to the type and the abnormality degree in having the equipment of abnormal cause of abnormal cause, varying in size of the amplitude of the wavelength at the frequency location place of 8Hz, 33Hz or 50Hz.
Similarly, because according to equipment and abnormal cause with abnormal cause, the measurement characteristics value departs from the degree difference of specialized range, when adjustment had the equipment of abnormal cause, the characteristic value that characteristic value that obtains before adjustment and adjustment back obtain changed little.
In this case, in view of the work efficiency of goods processing, and the Products Quality precision, operating personnel can judge the adjustment that does not need the equipment in the execute exception state.
Hereinafter, adjusting gear 107 will be described, and wherein, adjustment result can be shown, the change situation of the change degree of the characteristic value of acquisition according to the equipment of designated state abnormal cause.
As shown in figure 11, adjusting gear 107 is different from adjusting gear 7 parts and is also to provide degree of influence computing unit 23 except that the structure of above-mentioned adjusting gear 7.When information based on the power spectrum that receives from the information of the equipment to be adjusted of unusual estimation unit 25 notices with from cycle information detecting unit (data acquisition unit and mapping computation cell) 24, when adjusting equipment to be adjusted, the degree of influence of the variation of degree of influence computing unit 23 evaluation characteristic values.
In addition, the degree of influence that characteristic value changes is after the adjustment of finishing equipment to be adjusted, the expectation value of the change degree of the characteristic value of acquisition.
In addition, the difference of 7 of adjusting gear 107 and adjusting gears is as follows.
That is, adjusting gear 107 is different from adjusting gear 7 parts and is by indication output unit 19, carries out any one adjustment indication of the processing machine 5a and the processing machine 5b of adjustment unit 26.
In addition, adjustment unit 26 is different from any one adjustment indication that adjustment unit 18 parts are to receive from indication output unit 19 processing machine 5a and processing machine 5b, and based on this information, is identified for the policy of the setting value change of processing machine 5a or processing machine 5b.
Adjustment unit 26 is different from adjustment unit 18 parts and is that adjustment unit 26 obtains the histogrammic information by the characteristic value 31 that adds up to unit 13 to gather, and based on the information that is obtained, is identified for the policy of the setting value change of processing machine 5a or processing machine 5b.
In addition, cycle information detecting unit 16 parts that cycle information detecting unit 24 is different from adjusting gear 7 are, for detecting the not periodicity of the characteristic value in specialized range, replace equation (2) to (4), use power spectrum by the arithmetic operation results acquisition of FFT
In addition, unusual estimation unit 25 unusual estimation unit 17 parts that are different from adjusting gear 7 are that unusual estimation unit 25 will represent information notification degree of the influence computing unit 23 of estimating apparatus to be adjusted.
In addition, in adjusting gear 107, represent with part identical in adjusting gear 7 and with the descriptions thereof are omitted with identical mark.
Here, in degree of influence computing unit 23, will describe relevant after the adjustment of finishing equipment to be adjusted, with the flow process of the computing of the expectation value of the change degree of the characteristic value that obtains.
At first, cycle information detecting unit 24 by sequence data service time, by FFT, is carried out arithmetical operation based on the characteristic value 31 and the transmission serial number of processing and measure the goods of its characteristic value of storage in information memory cell 12.Then, power spectrum and the time series data that is obtained is sent to degree of influence computing unit 23.
In addition, unusual estimation unit 25 is informed degree of influence computing unit 23 with the result of the estimation processing of abnormal cause.
About being estimated as the equipment of abnormal cause, that is, be estimated as equipment to be adjusted, degree of influence computing unit 23 calculates after adjusting equipment to be adjusted the change of the change degree in the characteristic value by using the power spectrum that obtains from cycle information detecting unit 24.
Then, the information with the change of the relevant change degree that calculates is sent to indication output unit 19 so that show.
Hereinafter, will describe by degree of influence computing unit, after equipment to be adjusted is adjusted, the computing of the change of the change degree in the characteristic value.
(adjusting the computing of the change of back change degree)
When will be by FFT, when the frequency that the result of the arithmetical operation on time series data obtains was considered as sine wave, by FFT, the power spectrum that obtains with respect to time series data be corresponding to 2 powers of the amplitude of each period frequency component.
For this reason, increase the result of the power spectrum of FFT, it is proportional with the second power (that is deviation) of the standard deviation of time series data (removing the influence of the mean value in the time series data) basically to remove mean value component (with respect to the offset component of frequency 0).That is, before proofreading and correct unusual article, when the summation (removing the FFT power spectrum of frequency 0) of all FFT power spectrum be " P_all ", and when proofreading and correct all standard deviations before the unusual article and being " σ _ all ", determine following equation (5), wherein, k is any number.
P_all=K·(σ_all) 2 (5)
In addition, when passing through FFT, with respect to the result of seasonal effect in time series arithmetical operation with having when representing as 0 amplitude of average level, with respect to the offset component of frequency 0 for by the inverse Fourier transform with respect to that value, the value that the recovery time sequence data is required.
Wherein, about abnormal cause, any one that suppose measuring machine 6a to 6c is in the abnormality, and proofreaies and correct the measuring machine in the abnormality.Similarly, by proofreading and correct the measuring machine in the abnormality, the frequency component of the power spectrum that the 33Hz place that represents when any one of measuring machine 6a to 6c is in abnormality occurs reduces to approaching 0 (white noise position) (the seeing Figure 12) that be about.
In this case, by deriving before the frequency component of the power spectrum that reduces 33Hz place, the standard deviation after the standard deviation minimizing, approx estimated time sequence data the reduction of standard deviation.Promptly, before any one abnormality of correcting measuring machine 6a to 6c, the FFT at 33Hz place power spectrum be the reduction of " P3 " and the standard deviation after any one abnormality of correcting measuring machine 6a to 6c when " σ 3 ", set up relation by following equation (6) expression.
P3=K·(σ3) 2 (6)
Therefore, degree of influence computing unit 23 is carried out by the following equation (7) of the relation derivation of equation (5) and equation (6) and the arithmetical operation of (8), so that calculate the difference between all characteristic values that obtain and all characteristic values that obtaining after the correction before proofreading and correct abnormal cause
At first, the following equation (7) that the relation by user's formula (5) and equation (6) obtains, the reduction of the standard deviation after any one abnormality of calculation correction measuring machine 6a to 6c.
σ 3 = σ _ all * P 3 / P _ all - - - ( 7 )
σ 3: the reduction of proofreading and correct unusual article (any one of measuring machine 6a to 6c) back standard deviation.
σ _ all: proofread and correct all preceding standard deviations of unusual article (any one of measuring machine 6a to 6c).
P3: unusual article (any one of measuring machine 6a to 6c) are preceding proofreading and correct, the FFT power spectrum at 33Hz place.
P_all: it is preceding to proofread and correct unusual article (any one of measuring machine 6a to 6c), all FFT summed power spectrum (except that the FFT power spectrum of frequency 0).
Therefore, (equation (8) can be illustrated in the standard deviation of all characteristic values of any one unusual back measurement of correcting measuring machine 6a to 6c by following equation.
At the unusual standard deviation=σ _ all-σ 3... (8) that proofreaies and correct all characteristic values of measuring the back
Similarly, by in this way, carry out arithmetical operation, influence degree computing unit 23 is with respect to the characteristic value in the specialized range, the change degree of the characteristic value before and after the calculation correction abnormal cause, and result of calculation is sent to indicates output unit 19.
In addition, from time series data, can obtain to be used for all values before the correction of abnormal cause of above-mentioned arithmetical operation.That is, degree of influence computing unit 23 can calculate these values based on the information and the time series data of the power spectrum that receives from cycle information detecting unit 24.
In addition,, substitute the power spectrum that occurs in certain power, can obtain the reduction of the standard deviation after proofreading and correct these abnormal causes in fact by value with the white noise scope.
For this reason, before adjustment was used for unusual reason, degree of the influence computing unit 23 of adjusting gear 107 can calculate the change degree of the characteristic value after adjusting abnormal cause.
In addition, adjusting gear 107 can be to the change degree of the characteristic value behind the abnormal cause that indication output unit 19 output adjustment are calculated, and operating personnel can judge whether the adjustment of execute exception reason thus.
In addition, different with the adjusting gear 107 of the change degree that shows adjusted characteristic value, adjusting gear 7 can be configured to basis by the quality precision of calculating from goods to be processed in advance, judge exist/not have the necessity of automatic adjustment abnormal cause, and judged result is outputed to indication output unit 19.
Hereinafter, will the quality precision of being calculated by goods to be processed according in advance be described, judge necessity that exist/does not have automatic adjustment abnormal cause and the structure that judged result is outputed to the adjusting gear 207 of indication output unit 19.
As shown in figure 13, judgment means 207 is different from judgment means 7 parts and is except that the structure of above-mentioned adjusting gear 7, and warning identifying unit 27 also is provided, and information memory cell 12 further storage change tolerance information 33.
Change tolerance information 33 and be in the reduction of the standard deviation of the abnormality of estimating relevant equipment for abnormal cause and be when standard deviation is equal to or less than reduction at least, eliminate the value of the necessity of adjustment abnormal cause.Operating personnel by operation line production system 100 set in advance this value.
In addition, warning identifying unit 27 judges whether the adjustment of execute exception reason based on the information of the power spectrum that receives by the information of the equipment to be adjusted of unusual estimation unit 25 notices, from cycle information detecting unit 24 with in the variation tolerance information of information memory cell 12 storages.According to result of determination, when the adjustment of the equipment that needs the execute exception reason, warning identifying unit 27 will represent that the information of warning outputs to and indicate output unit 19.
In addition, below, will describe relevant to warning identifying unit 27, the determination processing of the adjustment of execute exception reason whether.
In addition, the difference of adjusting gear 207 and adjusting gear 7 is as follows.
That is, adjusting gear 207 is different from adjusting gear 7 parts and is by indication output unit 19, carries out any one adjustment indication of the processing machine 5a or the processing machine 5b of adjustment unit 26.
In addition, adjustment unit 26 is different from adjustment unit 18 parts and is that adjustment unit 26 receives the adjustment indication of processing machine 5a or processing machine 5b from indication output unit 19, and indicates unusual estimation unit 17 to stop unusual estimation and handle.
In addition, adjustment unit 26 is different from adjustment unit 18 parts and is that adjustment unit 26 obtains by the histogram information of the characteristic value 31 that adds up to unit 13 to add up to and based on this information, is identified for the policy that the setting value of processing machine 5a or processing machine 5b changes.
In addition, cycle information detecting unit 16 parts that cycle information detecting unit 24 is different from adjusting gear 7 are to replace equation (2) to (4) into detecting the not periodicity of the characteristic value in specialized range, use the power spectrum by the arithmetic operation results acquisition of FFT
In addition, unusual estimation unit 25 unusual estimation unit 17 parts that are different from adjusting gear 7 are that unusual estimation unit 25 will represent information notification degree of the influence computing unit 23 of estimating apparatus to be adjusted.
In addition, in adjusting gear 207, represent with part identical in adjusting gear 7 and with the descriptions thereof are omitted with identical mark.
Wherein, relevant with describing whether by adjusting gear 207, the flow process of the determination processing of the adjustment of execute exception reason.
At first, cycle information detecting unit 24 by sequence data service time, by FFT, is carried out arithmetical operation based on the characteristic value 31 and the transmission serial number of processing and measure the goods of its characteristic value of storage in information memory cell 12.Then, the power spectrum that is obtained is sent to degree of influence computing unit 23.
In addition, unusual estimation unit 25 is informed degree of influence computing unit 23 with the result of the estimation processing of abnormal cause.
When unusual estimation unit 25 receives the information of the equipment of estimating as abnormal cause, warning identifying unit 27 is based on the power spectrum information and the characteristic value 31 time of reception sequence datas that receive from cycle information detecting unit 24.
In addition, warning identifying unit 27 obtains the variation tolerance information 33 of storage in information memory cell 12.
Then, warning identifying unit 27 will be based on time series data, power spectrum information and change threshold value that tolerance information 33 obtains with respect to time series data based on measured characteristic value 31, the power spectrum that is obtained by the arithmetical operation of FFT compares.Then, warning identifying unit 27 judges whether the information of expression warning is outputed to indication output unit 19.
Wherein, with describe with respect to time series data based on measured characteristic value 31, the computing method of the threshold value that the power spectrum that is obtained by the arithmetical operation of FFT compares.
At first, warning identifying unit 27 is carried out the arithmetical operation of following equation (9) so that calculated threshold.In addition, wherein, for example, suppose that by measuring machine 6a to 6c any one causes abnormal cause.
Q3=P_all*(γ3/σ_all) 2 (9)
Q3: with respect to before correcting measuring machine 6a to 6c any one unusual, the threshold value of the FFT power spectrum at 33Hz place.
P_all: at any one unusual preceding all FFT power spectrum (except that the FFT power spectrum of frequency 0) of correcting measuring machine 6a to 6c
σ _ all: at any one unusual all preceding standard deviations of correcting measuring machine 6a to 6c
γ 3: allow the value as the reduction of the standard deviation behind correcting measuring machine 6a to 6c any one unusual.
Wherein, as mentioned above, the value of P_all can be carried out warning identifying unit 27 calculating of arithmetical operation by with respect to the time series data based on measured characteristic value 31 by FFT.
In addition, as mentioned above,,, can calculate value of σ _ all by warning identifying unit 27 based on time series data.
In addition, as mentioned above, by the value of information memory cell 12 acquisition γ 3, as changing tolerance information.
In addition, the Q3 that calculates by above-mentioned arithmetical operation is before the unusual and power spectrum of proofreading and correct the change degree that allows characteristic value is set to threshold value, the FFT power spectrum at 33Hz place.
Therefore, the threshold value (Q3) that warning identifying unit 27 will calculate by above-mentioned arithmetical operation with respect to time series data based on measured characteristic value 31, the power spectrum (P3) by FFT calculating compares.According to comparative result, if the former value is less than the latter's value (Q3<P3), warn identifying unit 27 will represent that the information of warning outputs to the indication output unit.
That is, when the relation of " Q3<P3 " was set up, with respect to the time series data based on the characteristic value 31 of actual measurement, the power spectrum that the result of the arithmetical operation by FFT obtains can be greater than the tolerance value of power spectrum.That is, when the relation of " Q3<P3 " is set up, with respect to the characteristic value in the specialized range, the change degree out-of-size scope of the characteristic value 31 of actual measurement.
In addition, according to the quality precision of calculating by goods to be processed, can pre-determine the tolerance information (γ 3) 33 that changes.Therefore, when requiring the high-quality precision, the value that changes tolerance information (γ 3) diminishes.
Similarly, adjusting gear 207 has warning identifying unit 27, thereby need to judge whether the adjustment of execute exception reason.
Therefore, in view of when the estimating apparatus adjusted as abnormal cause, the change of the change degree of characteristic value can be judged the equipment that is estimated as abnormal cause of whether adjusting automatically.
In addition, warning identifying unit 27 is by the arithmetical operation of equation (9), whether judges calculated threshold and output warning.Yet, for ease of understanding, can be configured to threshold value is shown on the indication output unit 19 and simultaneously all measurement characteristics values 31 are transformed into standard deviation, replace power spectrum, thereby threshold value is set by FFT calculating.

In addition, as mentioned above, data acquisition unit 111 receives the channel number that is used to specify each measuring machine 6a to 6c from measuring machine 6a to 6c.Therefore, even when the time,, also can gather according to the time series data that transmits serial number by reference channel number simultaneously by three measuring machine 6a to 6c measurement characteristics values.In addition, data acquisition unit 111 is sent to converter unit 113 with the time series data of being created.
Converter unit 113 by FFT (fast fourier transform), is carried out frequency conversion based on the time series data of the characteristic value of being created by data acquisition unit 111.Converter unit 113 is sent to frequency masks unit 114 with transformation results, as frequency data.
When time series data being carried out frequency transformation, on frequency axis, the frequency data of transformation results are divided into sinusoidal component and cosine component by FFT.In addition, the summation of the second power of the second power of sinusoidal component and cosine component becomes the power spectrum of that frequency.
In addition, converter unit 113 is configured to carry out frequency conversion by FFT, but is not limited thereto.For example, can carry out frequency conversion by other transform methods, such as wavelet transform or the like.
Other data (non-shielding component) of the frequency data that receive corresponding to the frequency data (shielding component) of each equipment with from converter unit 113 are divided in frequency masks unit 114.In addition, the shielding component be near fundametal component frequency data and corresponding to the overlapping component of each equipment.That is, the shielding component is the data stream (set of frequency power) according to the transformation results of passing through FFT.In addition, frequency power is the integrated value corresponding to the power spectrum of the frequency of each equipment.That is, frequency power is the result's of the frequency conversion by FFT the single data of specified point.
Frequency masks unit 114 receives and is illustrated in the mode of operation, the information of the quantity of each equipment, and from adjustment control module 115 information that receive, that be used to specify each equipment (measuring machine 6, machine table 5 and second processing machine 5), and, divide frequency data based on information.Then, the frequency data of being divided are sent to inverse transformation block as described below 119.In addition, the detailed description that the division of data is handled will be described below by frequency masks unit 114.
In addition, frequency masks unit 114 will be sent to corresponding to the integrated value of the power spectrum of the frequency of each equipment and adjust control module 115.The integrated value of the power spectrum of frequency is used for adjustment control module 115 as described below so that the adjustment of specifying equipment to be adjusted or determining whether to finish to be appointed as the equipment of equipment to be adjusted is handled.
Adjusting control module 115 controls is included in according to each part in the adjusting gear 307 of present embodiment.Particularly, adjust control module 115 and indication is outputed to measuring machine setup unit 116, processing machine setup unit 117 and door setup unit 118, or adjust setting value so that be adjusted at the quantity of the equipment in each the mode of operation of measuring machine 6, machine table 3, second processing machine 5 and first processing machine 1500.

That is, by FFT, the power spectrum that obtains according to the arithmetic results of time series data is corresponding to the second power of the amplitude of the frequency component in each cycle.Then, the summation of power spectrum is proportional with the second power of the standard deviation of time series data basically.Therefore, following relation is set up.
P_all=K·(σ_all) 2 ...(1)
(P_all is the summation of power spectrum)
(K is an arbitrary constant)
(σ _ all is the standard deviation in the time series data)
Therefore, adjust the relation of control module 115 by user's formula (1), the power spectrum by corresponding to 114 each equipment that receive from the frequency masks unit calculates the standard deviation of each equipment, and based on standard deviation, specifies equipment to be adjusted.
In addition, in as described below " adjustment of equipment is handled ", adjust control module 115 and whether be equal to or less than the precalculated position, carry out the determining of adjustment of the equipment that finishes to be appointed as abnormal cause according to the size of standard deviation.
But information memory cell 121 is readable/write record media, and storage from the time point of adjusting equipment to when by measuring machine 6, measure after adjustment the time delay 130 of the time during by the characteristic value of the goods 9 of equipment processing.
As shown in figure 15, the time of expression time delays 15 till the goods 9 by the processing of adjustment equipment arrive measuring machine 6.Therefore, by the information memory cell 121 that is used for each equipment will be stored in time delay 130, can prevent that data acquisition unit 111 is captured in the characteristic value of goods of processing before the adjustment of equipment 9 and the goods of processing 9 confusedly after adjustment.
In addition, information memory cell 121 further store predetermined range information 131.Specialized range information is the information of the scope of the characteristic value of expression when fabricated product 9 satisfies definite quality.
Measuring machine setup unit 116 receives the information of expression mode of operation from each measuring machine 6a to 6c, and the result who is obtained informed adjust control module 115 or according to the indication that comes self-adjusting control module 115, the ON/OFF (ON/OFF) of the operation of control survey machine 6a to 6c.
Processing machine setup unit 117 obtains the information of expression mode of operation from each second processing machine 5a to 5h, and the result who is obtained informed adjust control module 115, or, control the ON/OFF of the operation of the second processing machine 5a to 5h according to the indication that comes self-adjusting control module 115.If adjust ON/OFF according to the indication that comes self-adjusting control module 115, processing machine setup unit 117 designation data collecting units 111 were gathered by the time (time delay 130), from the data of adjusting time delay up to measuring after adjustment, till the characteristic value by the goods 9 of second processing machine, 5 processing by measuring machine 6.In addition, the information of representing time delay 130 is stored in the information memory cell 121 in advance, and processing machine setup unit 117 designation data collecting units 111 are with reference to image data time delays 130 that is stored in the information memory cell 12.
In addition, processing machine setup unit 117 is configured to control the ON/OFF of the operation of each first processing machine 500a to 500c according to the indication that comes self-adjusting control module 115.
Door setup unit 118 is adjusted the goods 9 in any one that is contained in machine table 3a to 3p according to the indication that comes self-indication control module 115.In addition, the relevant machine table 3 of door setup unit 118 management is held the information of goods 9.
Particularly, door setup unit 116 is according to the rotation of turntable 4, and whether control gate 2 is contained in the machine table 3 so that adjust goods 9.For example, when when adjusting control module 115 and receive goods 9 and be not contained in the indication of the meaning the machine table 3, door setup unit 118 is in conjunction with the rotation of turntable 4, specifies goods 9 to be contained in time in the machine table 3.Then,, door 2 is put down travelling belt 8, then, carry out and adjust so that goods 9 are not contained among the machine table 3a in that time.
In addition, in this way, when changing machine table 3 so that holding goods 9, door setup unit 118 designation data collecting units 111 are captured in the data after pass from the time point that changes time delay 130.
In addition, during gathering characteristic value at data acquisition unit 111, when breaking down in first processing machine 500, second processing machine 5, machine table 3 or measuring machine 6, each energy designation data collecting unit 111 of processing machine setup unit 116, processing machine setup unit 117 and door setup unit 118 stops the collection of data.
114 receptions shield the frequency data of components or non-shielding component and on the frequency data that received, carry out inverse Fourier transform (hereinafter, being called contrary FFT) inverse transformation block 119 from the frequency masks unit.Handle by contrary FFT, inverse transformation block 119 generates based on the time series data of the frequency data of shielding component or based on the time series data of the frequency data of non-shielding component.Then, inverse transformation block 119 is sent to indicative control unit 120 with the time series data that is generated.
Indicative control unit 120 shows the time series data that receives from inverse transformation block 119.Because indicative control unit 120 demonstrations from the time series data of the shielding component of time series data, can clearly be represented the cycle of the appearance of abnormal characteristic value.
That is, although as described below, the shielding component does not comprise offset component, and only represents the variation corresponding to the characteristic value of the frequency band that is extracted as the shielding component.Therefore, the time series data by the result according to the contrary FFT that shields component obtains only shows the skew by the characteristic value that causes unusually of equipment.
In addition, this change list is shown in the specialized range, from the distribution of the skew of ideal value.In addition, specialized range is the scope of the characteristic value when fabricated product 9 satisfies definite quality.In the present embodiment, represent specialized range by upper limit setting and undergage definite value.
In addition, the difference between the ideal value in skew expression measurement characteristics value and the specialized range.In addition, ideal value is the intermediate value between upper limit setting and undergage definite value.
On the other hand, when supposing the adjustment that finishes the unusual equipment that takes place, by making the time series data of the non-shielding component of indicative control unit 120 demonstrations, the time series data of energy characterization value.Therefore, after unusual the generation estimated in the adjustment of equipment, can represent and the skew of the characteristic value of specialized range.
In addition, indicative control unit 120 also can be based on the specialized range information 131 of storage in information memory cell 12, from the value of the time series data of the contrary FFT acquisition by non-shielding component, exports the not quantity of the value in specialized range.
In addition, the time series data that indicative control unit 120 also can obtain based on the contrary FFT by non-shielding component, basis of calculation deviation, and outputting standard deviation.
Input block 121 receives indication and the indication that is received is outputed to adjustment control module 115 from the user.For example, from user's indication can comprise be used to select the indication information of a plurality of adjustment processing, after equipment is adjusted, the unusual improvement prediction processing of characteristic value, and the adjustment of the equipment of the abnormal cause of characteristic value handles, as described below.In addition, if desired, comprise the required information of above-mentioned each processing, such as parameter or the like.
(reason of unit exception)
Wherein, in line production system 100 according to present embodiment, will be with reference to Figure 16, the not abnormal cause specialized range of the characteristic value measured from goods 9 is described.In addition, Figure 16 is the figure of the abnormal cause of the expression second processing machine 5a to 5h, machine table 3a to 3p, measuring machine 6a to 6c and each equipment.
As mentioned above, the line production system 100 according to present embodiment has the first processing machine 500a to 500c, the second processing machine 5a to 5h, machine table 3a to 3p and measuring machine 6a to 6c.For this reason, when any one of each member of normal running not, the measurement characteristics value becomes unusually.As the reason of normal running first processing machine 500 and second processing machine 5 not, can example first processing machine 500 or second processing machine 5 in machine error, or wearing and tearing that cause by processing.In addition, about the reason of normal running processing machine 3 not, can be exemplified as the unclamping of installation portion that is used for that goods are installed in the anchor clamps of the member on the machine table 3 and fragment is connected to goods.In addition, about the reason of normal running measuring machine 6 not, the measuring error in can example measuring machine 6, skew of measuring position or the like.
Therefore, under any one situation of not the normal running second processing machine 5a to 5h, machine table 3a to 3p or measuring machine 6a to 6c, when fabricated product 9, for example, in the characteristic value of measuring by goods 9, observe the following phenomenon shown in Figure 17 A to 17C.
Therefore, in Figure 17 A to 17C,, use at " interval between part " as the example of measurement characteristics value.Therefore, in Figure 17 A to 17C, Z-axis is arranged to mm (millimeter), it is the unit of expression " interval between part ", and transverse axis is arranged to measure the goods number of its characteristic value.
That is, when any one of eight second processing machine 5a to 5h of normal running not, the relation between the characteristic value of measuring about the serial number of the goods 9 that will transmit with from goods 9, shown in Figure 17 A, characteristic value is not once in per eight specialized range.
In addition, when any one of not normal running machine table 3a to 3p, the relation between the characteristic value of measuring about the serial number of goods to be transmitted 9 with from goods, shown in Figure 17 B, characteristic value once had not been used for per 16 specialized range.
In addition, when any one of normal running measuring machine 6a to 6c not, the relation between the characteristic value of measuring about the serial number of goods to be transmitted 9 with by goods, shown in Figure 17 C, characteristic value once had not been used for per three specialized range.Similarly, when any one of not normal running second processing machine 5, machine table 3 or measuring machine 6, can understand that the characteristic value that is obtained periodically becomes the not value in specialized range.
In addition, when in any one of the first processing machine 500a to 500h, occurring when unusual, become unusually by the quality of all goods 9 of the first processing processing.That is,, do not observe above-mentioned periodicity owing to all characteristic value overshoot scopes of measuring from goods 9.
Therefore, in the present embodiment, about the transmission serial number of goods with from the relation between the characteristic value of goods measurement, the time series data that will have serial number is considered as time shaft.Then, according to the frequency conversion by the time series data of FFT of the adjusting gear 307 of present embodiment, the calculated rate data based on frequency data, are specified equipment to be adjusted, or are adjusted this equipment.
Here, at first, will time series data and the relation between the data of the time series data after the frequency conversion be described with reference to figure 18A, 18B to 20A.Suppose about goods 9, measure its characteristic value, the quantity of sample is 1024.
For example, shown in the time series data of Figure 18 A, when based on mean value, i.e. from first to the 8th cycle, when the waveform of time series data is sinusoidal wave, the characteristic value of the first and the 5th goods becomes mean value, the characteristic value of second to the 4th goods 9 is equal to or greater than mean value, and the characteristic value of the 6th to the 8th goods 9 is equal to or less than mean value, in the data of the time series data before frequency conversion, shown in Figure 18 B,, generate power spectrum only at frequency place corresponding to the quantity of carrying out the equipment of processing.
In this case, locate to occur offset component (on average) at frequency f j=0 (unlimited cycle), only fj=(1,2,3 ..., 1023) each frequency component in the change component appears.For this reason, in this example, frequency f j becomes 128, is the value that obtains divided by the quantity 8 of equipment into the quantity 1024 of the sample of time series data by gathering.That is, compose at the position of frequency f j=128 emergent power.
On the other hand, shown in Figure 19 A, about first to the 8th goods 9, only the time series data when the characteristic value of the goods of being processed by second equipment 9 significantly exceeds mean value is in the pulse shape in cycle 8.When carrying out frequency conversion on this time series data, shown in Figure 19 B, the emergent power spectrum has identical size corresponding in the frequency component (fundametal component) of the quantity 8 of equipment and its integer multiple.In addition, as mentioned above,, become sinusoidal wave situation with time series data and compare, the size of the power spectrum that is generated is diminished because standard deviation is diminished.
In addition, shown in Figure 20 A, about first to the 8th goods 9, only the time series data when the characteristic value of the second and the 6th goods 9 exceeds mean value significantly is considered as the pulse shape in cycle 4.Promptly, similarly, only exceeding significantly under the situation of time series data of mean value when the second and the 6th characteristic value, time series data is handled simultaneously by four equipment, and the time series data only can be considered as that the characteristic value of a fabricated product 9 exceeds mean value significantly in by equipment the time.
Therefore, locating corresponding to frequency (fundametal component) fj=256 of the quantity 4 of equipment with corresponding to the frequency (overlapping component) of its integral multiple, the power spectrum of equal height appears having.Yet the twice of the frequency in cycle 4 becomes the cycle 2, but when the cycle is equal to or less than two, can not distinguish the difference according to the frequency of its sampling.Therefore, in Figure 20 B, single tangible power spectrum appears.
In addition, when the time series data shown in the time series data shown in Figure 20 A and Figure 19 A has same magnitude, make the former standard deviation bigger.For this reason, the size of the power spectrum that obtains greater than frequency conversion of the size of the power spectrum that obtains of the frequency conversion by the time series data shown in Figure 20 A by the time series data shown in Figure 19 A.
In addition,, for example, when the characteristic value of the second and the 5th goods 9 exceeds mean value significantly, generate little frequency power about first to the 8th goods 9, rather than fundametal component and/or overlapping component.Yet, only otherwise change the quantity of the equipment that is used to sample, do not exist in fundametal component and/or the overlapping component, not the situation of frequency of occurrences power.
By the relation between frequency data after time series data and the frequency conversion, the adjustment of describing the equipment that the number of devices adjustment is handled, the improvement expection is handled and carried out in according to the adjusting gear 307 of present embodiment is handled.
(number of devices adjustment processing)
Wherein, at first, will describe " number of devices adjustment processing " with reference to Figure 21.In addition,, carry out to adjust, make, can not become other twice from being used for each the quantity of equipment of production and processing of second processing machine 5, machine table 3 and measuring machine 6 so that before the equipment of specifying abnormal cause about " number of devices adjustment processing ".
That is, as mentioned above, about the measured characteristic value with measure relation between the transmission serial number of goods 9 of its characteristic value, in the time will transmitting serial number and be considered as time shaft, according to the adjusting gear 307 creation-time sequence datas of present embodiment.Then, be configured on time series data to carry out frequency conversion and equipment is appointed as abnormal cause.
In this case, when following condition was set up, the problem of the equipment of abnormal cause can not be accurately specified in existence.
That is, about the operand of second processing machine 5, the operand of machine table 3 and the operand of measuring machine 6, when having concerning of doubling each other, a fundametal component another overlapping component that superposes can interfering frequency.For this reason, exist adjusting gear 307 accurately not specify problem from the result of the frequency conversion of the time series data of the characteristic value that obtained as the equipment of abnormal cause.
Therefore, in the present embodiment,, be configured to adjust each the quantity of equipment of mode of operation of production and processing that is used for second processing machine 5, machine table 3 and measuring machine 5 for not making a fundametal component another overlapping component that superposes.
Particularly, at first, measuring machine setup unit 116, processing machine setup unit 117 and door setup unit 118 confirm to be used for the quantity (step S111) (hereinafter, being called S111) of equipment of the production and processing of each equipment.In addition, the quantity that is used for the equipment of production and processing is when second processing machine 5 and measuring machine 6, the quantity of the equipment in the mode of operation (opening state), and be when machine table 3, the quantity of the equipment of goods can be installed.
For example, processing machine setup unit 117 confirms in each of the second processing machine 5a to 5h, and power supply is for opening state or off status, thereby affirmation is used for the quantity of equipment of mode of operation of the production and processing of second processing machine 5.In addition, for example, measuring machine setup unit 116 confirms in measuring machine 6a to 6h, and power supply is for opening state or off status, thereby affirmation is used for the quantity of equipment of mode of operation of the production and processing of measuring machine 6.In addition, for example, the management of door setup unit 118 is in which time, door 2, thus be adjusted at the quantity of the equipment in the mode of operation of the machine table 3a to 3p that holds goods 9.
Then, measuring machine setup unit 116, processing machine setup unit 117 and door setup unit 118 are informed and are adjusted the quantity of control module at the equipment of the affirmation of the mode of operation that is used for production and processing.
Wherein, judge whether input block 2 receives the request (S112) that is used for number of devices adjustment processing.Therefore, when judging that input block 2 receives the request (S112 is "Yes") that is used for the number of devices adjustment and handles, second processing machine 5 is used for each the quantity and the measuring machine 6 of equipment of production and processing of machine table 3, judges whether to exist the combination (S113) of the equipment with double relation.
Promptly, adjusting control module 115 is used for judging the combination that whether has the equipment with double relation from the information of the quantity of the equipment of the production and processing of each reception of measuring machine setup unit 116, processing machine setup unit 117 and door setup unit 118 based on expression.
Therefore, be under the situation of "Yes" in step S113, adjust the number of devices that control module 115 is adjusted the equipment that is used to have maximum a plurality of equipment.
In the line production system 100 according to present embodiment, the quantity of machine table 3 is that the quantity of 16, the second processing machines 5 is 8, and the quantity of measuring machine 6 is three, thereby the quantity of machine table 3 is twices of the quantity of processing machine 5.Therefore, adjust the working (machining) efficiency of control module 115, determine to adjust the quantity of machine table 3 in view of goods 9.
Especially, adjust the quantity of equipment that control module 115 indication door setup units 11 will be used for the production and processing of machine table 3 and change over 14 from 16.In addition, according to the judged result of step S13, under the situation of "No", the process former state finishes.
Similarly, the quantity of the equipment by will being used for production and processing changes over 14 from 16, and the quantity of machine table 3 is 14, the quantity of second processing machine 5 is 8, the quantity of measuring machine 6 is 3, thereby with respect to the quantity of the equipment in mode of operation, does not have the combination of integral multiple relation.That is, about the quantity of the machine table in the mode of operation 3, the quantity of second processing machine 5 in the mode of operation, and the quantity of the measuring machine in the mode of operation 6, the relation that does not become another multiple is set up.
Therefore, as the result based on the frequency conversion of time series data, when specifying the equipment of abnormal cause, in the adjusting gear 307 according to present embodiment, fundametal component and overlapping component do not overlap each other, thereby can prevent interfering frequency.For this reason, the adjusting gear according to present embodiment can pass through degree of precision, the equipment of appointment abnormal cause.
In addition, as mentioned above, when change was used for the number of devices of production and processing, in the line production system 100 according to present embodiment, each operation of equipment was as follows.For example, during the quantity of the machine table 3 in changing mode of operation, as mentioned above, realize by the ON/OFF that makes a setup unit 118 control gates 2.More particularly, for example, in the time can not using machine table, door setup unit 118 control opening-closing doors 2 are not so that goods 9 are contained among the machine table 3a.
In addition, during the quantity of second processing machine 5 in changing mode of operation, as mentioned above, can be by making processing machine setup unit 117 disconnect the power supply of second processing machine 5 that will stop and second processing machine 5 that conducting is in the off-position is realized.For example, when the power-off of the second processing machine 5a, processing machine setup unit 117 indication travelling belts 8 will move to towards the position of the second processing machine 5h towards the goods 9 that the second processing machine 5a places by next motion.
In addition, in line production system 100,, for example, use the second processing machine 5a or the second processing machine 5h about the second processing machine 5a that will cut off the power supply according to present embodiment.That is, preferably select adjacent with second processing machine 5 of another on a side only one.
That is, be used for the viewpoint of quantity of second processing machine 5 of production and processing from adjustment, at least one of the second processing machine 5a to 5h that can cut off the power supply.Therefore, for example,, can adjust the transfer rate of goods 9, maybe can provide transmission that a (not shown) adjusts goods 9 at interval so that towards the second processing machine 5a to be cut off the power supply by travelling belt 8.About the adjustment of relevant transmission goods 9, any one situation of the second processing machine 5b to 5g that cuts off the power supply is more complicated than the situation of the outage second processing machine 5a or the second processing machine 5h.
For this reason, to transmit the structure that goods 9, the second processing machine 5a or the second processing machine 5h be de-energized be desirable from being easy to control.
In addition, during the quantity of the measuring machine 6 in changing mode of operation, as mentioned above, realize by making measuring machine setup unit 116 measuring machine 6 measuring machines 6 unavailable or that turn in the off-position that cut off the power supply.
For example, when outage measuring machine 6a, travelling belt 8 is adjusted the motion of goods 9 so that will move to towards next measuring machine 6c towards the goods 9 of measuring machine 6a.In addition, when outage measuring machine 6b, travelling belt 8 is adjusted the transmission interval of goods 9 to be transmitted, and when being placed in the face of measuring machine 6a with goods 9 of box lunch, another goods 9 is placed to towards measuring machine 6c.Can be by a plurality of doors being provided on the travelling belt and, facing measuring machine 6a and realize this adjustment by making another goods 9 when making goods 9 be placed to towards measuring machine 6c.
Wherein, when any one of any one or measuring machine 6 of second processing machine 5 stops, will the relevant control method that transmits goods 9 be described particularly with reference to Figure 28.In addition, wherein, by example, be described, wherein any one of measuring machine 6 stops.
In the present embodiment, as shown in figure 28, on travelling belt 8, provide a plurality of 200a to 200e.In addition, on the inlet end of the door on the transfer path of goods 9, provide sensor 201a to 201e.In addition, when not needing when describing distinctively, door 200a to 200d is called door 200 simply.On the other hand, when not needing when describing distinctively, sensor 201a to 201e is called sensor 201 simply.
In addition, door 200 ON/OFF are controlled the transmission of goods 9.On the other hand, sensor 201 detects the transmission of goods 9 and can realize by for example infrared sensor or the like.
The testing result ON/OFF of door 200 combined sensors 201.Below with reference to Figure 29, the relation between the ON/OFF of description door 200 and the testing result of sensor 201.
In addition,, sensor 201, door 200 and adjusting gear 307 are connected to each other, and are configured to a open/close state that adjusting gear 307 can manage and the testing result of sensor 200 although in Figure 28, do not illustrate particularly.That is, adjusting gear 307 is configured to carry out the ON/OFF indication of door, thus the open/close state of management door.In addition, adjusting gear 307 can be managed the ON/OFF of measuring machine 6, thereby obtains the quantity of the measuring machine 6 in mode of operation.
At first, about the open/close state of door 200, suppose that a 200a and door 200d open, and door 200b closes (S141) with a door 200c.In the open/close state of door 200, adjusting gear 307 judges whether measuring machine 6c is in out (S142) in the state.
Wherein, when measuring machine 6c was in out in the state, adjusting gear 307 transmitted indication so that open a 200a.By this indication, if door 200a opens (S143), at this time point, door 200a to 200c is in closed condition.Then, adjusting gear 307 is kept the open/close state of door 200 and is represented by till the information of goods 9 up to detecting from sensor 201d in current state, that is, and and when in step S144, being judged to be "No".Then, if receive the testing result (S144 be "Yes") of expression by goods 9 from sensor 201d, adjusting gear 307 sends to each door 200 with indication so that cut out a 200a and door 200c.
According to the indication that comes self-adjusting apparatus 307, if door 200a and door 200c close (S145), the open/close state of door, door 200a, door 200c and door 200d are in the closed condition.That is, goods 9 insert between door 201d and door 201c, and insertion goods 9 are placed in the face of being in out the measuring machine 6c of state.
In addition, when measuring machine 6c is not in out state (being "No" among the S142), about the open/close state of door, except that door 200a and door 200d, door 200c is in off status.
Then, adjusting gear 307 judges whether measuring machine 6b is in "on" position (S146).According to judged result, be in out (being "Yes" among the S146) if judge measuring machine 6b, adjusting gear 307 sends indication and cuts out a 200a.According to this indication, door 200a opens (S147).At this time point, about the open/close state of door 200, door 200c and door 200d are in closed condition.
Then, up to detecting expression from sensor 201c by till the information of goods 9, that is, when being judged to be "No" in step S148, adjusting gear 307 maintains current state with the open/close state of door 200.Then, if receive the testing result (S148 be "Yes") of expression by goods 9 from sensor 201c, adjusting gear 307 sends to each door 200 with indication so that cut out a 200a and door 200b.
According to the indication that comes self-adjusting apparatus 307, if door 200a and door 200b close (S149), about the open/close state of door 200, all 200a to 200d all are in the closed condition.In addition, goods 9 are placed between a 200b and door 200c, and only will put into goods 9 and be placed in the face of being in out the measuring machine 6b of state.
In addition, when measuring machine 6b is not in out state (being "No" among the S146), about the open/close state of door, except that door 200c and door 200d, door 200b is in closed condition.
Then, adjusting gear 307 judges whether measurement mechanism 6a is in "on" position (S150).According to result of determination, when judging that measuring machine 6a is in connection, (be "Yes" among the S150), adjusting gear 307 sends indication and cuts out a 200a.According to this indication, door 200a opens (S151).At this time point, about the open/close state of door 200, door 200b to 200d is in the closed condition.
Then, up to detecting expression from sensor 201b by till the information of goods 9, that is, when being judged to be not in step S152, adjusting gear 307 maintains current state with the open/close state of door 200.Therefore, (be ' being ' the S152, adjusting gear 307 sends indication and cuts out a 200a if receive the testing result of representing by goods 9 from sensor 201b.
According to the indication that comes self-adjusting apparatus 307, if door 200a closes (S153), about the open/close state of door 200, all 200a to 200d all are in closed condition.In addition, goods 9 are put between a 200a and door 200b, and the goods of being put into 9 are placed in the face of being in the measuring machine 6a of conducting state.
In addition, when measuring machine 6b is not in conducting state (S150 is ' denying '), about the open/close state of door, all doors 200 from door 200a to door 200d all are in closed condition.
Therefore, in the ordered state of the open/close state of door 200 and goods 9, measure the characteristic value of goods 9 by each measuring machine 6a to 6c.Then, if finish the measurement of characteristic value, adjusting gear 307 sends indication and opens a 200b to 200d, and 200b to 200d is in open mode with side door.Therefore, move by travelling belt 8 once more and put between a 200a and door 200b, door 200b and door 200c and/or door 200c and door 200d and the goods 9 that stop.Therefore, keep non-detection status up to each sensor 201b to 201d and reach the schedule time (being ' denying ' among the S155), keep current open/close state 200, and if the schedule time from non-detection status passage (being ' being ' the S155), handle turning back to step S144.
Similarly, by controlling the ON/OFF of each, goods 9 suitably are arranged in the face of being in the position of each measuring machine 6a to 6c in the "on" position.
In addition, in adjusting gear 307 according to present embodiment, when adjustment is in the quantity of the measuring machine 6 in the mode of operation, conducting or outage measuring machine 6.In addition, by the open/close state of control gate 200, as mentioned above, goods 9 are configured in the face of particular measurement machine 6.
In addition, in adjusting gear 307, in view of the working (machining) efficiency of goods 9, preferably be configured to pass through input block 121, input is set to the quantity (being in the minimum number of the equipment in the mode of operation) of the equipment of unavailable device.In addition, the minimum number that adjusting gear 307 can be configured to will be in the equipment in the mode of operation is stored in the information memory cell 121 in advance.
When disposing adjusting gear 307 by this way, in " number of devices adjustment processing ", can limit the quantity of unavailable device, thus, can prevent to reduce sharp the working (machining) efficiency of goods 9.
(improving expectation handles)
Then, will " improving expectation handles " be described with reference to Figure 22.Improving the expectation processing is to be used to represent specify the unusual equipment that takes place by adjusting, and how to improve the processing that the measured characteristic value departs from the expectation of ideal value.In addition, ideal value is the intermediate value between upper limit setting and undergage definite value.
When will when the quantity of arrangement measured characteristic value establishment is considered as time series data, passing through FFT by pressing the transmission order of goods 9, the frequency data that the frequency conversion of time series data obtains, execution " improvement expectation processing " by using.For this reason, improve the expectation processing,, need to carry out frequency conversion based on time series data for carrying out.
That is, data acquisition unit 111 obtains a plurality of measurement characteristics values according to the transmission serial number of goods 9 from measuring machine 6.In addition, if obtain predetermined a plurality of characteristic values, data acquisition unit 111 is configured to stop to gather characteristic value.
Then, based on predetermined a plurality of characteristic values that obtain, the time series data that data acquisition unit 111 will have the transmission serial number of goods 9 is created as time shaft (S121).Then, data acquisition unit 111 is sent to converter unit 113 with the time series data of being created.
In addition, in line production system 100, suppose by aforesaid " number of devices adjustment processing " according to present embodiment, about quantity at the equipment of the mode of operation of the production and processing that is used for each equipment, machine table 3 is that 14, the second processing machines 5 are 8, and measuring machine 6 is 3.Under this supposition, suppose that the time series data that obtains by the sample number 1024 that is used for goods 9 is for example shown in Figure 23 A.So, in time series data, seven characteristic values are not in specialized range, and are promptly unusual.
In the time series data shown in Figure 23 A, sign tends to integral body to be increased significantly.For this reason, when representing time series data by histogram, shown in Figure 23 B, DATA DISTRIBUTION is near rectangular shape.For this reason, the time series data shown in Figure 23 B can not be near specified distribution.Therefore, when the average or standard deviation that passes through with respect to these data, when calculating the quantity of the characteristic value in specialized range not, make apparent standard deviation (apparent standard deivation) become big, thereby the quantity of calculating the characteristic value in specialized range not is greater than the actual quantity of the characteristic value in specialized range not.
Therefore, for accurately calculating the not quantity of the characteristic value in specialized range, in the time series data of Figure 23 A, direct census is the quantity of the characteristic value in specialized range not.
In converter unit 113, based on the time series data that receives from data acquisition unit 11, execution is passed through the frequency conversion of FFT so that calculated rate data (S122).
Wherein, the frequency data that calculated as shown in figure 24.For example, when in any one of 14 machine table 3, occurring when unusual, with the quantity of equipment be 14 and the position of frequency f j=73 become the power spectrum of fundametal component, the variation of characterization value.In addition, by power spectrum, represent overlapping component in the position of frequency f j=146 and 219.
On the other hand, for example, when in any one of eight second processing machines 5, occurring when unusual, can be with the quantity of equipment 8 and the position of frequency f j=128 become the power spectrum of fundametal component, the variation of characterization value.In addition, can use the power spectrum of the position of frequency f j=256 and 384, represent overlapping component.
In addition, for example, when in any one of three measuring machines 6, occurring when unusual, can be with the quantity of measuring equipment 3 and the position of frequency f j=341 become the power spectrum of fundametal component, the variation of characterization value.Yet in this case, overlapping component becomes twice (fj=682) and three times (fj=1023) of frequency f j=341, and thus, the cycle is equal to or less than 2.For this reason, can not distinguish the frequency difference of its sample.Therefore, single power spectrum only appears at the position of frequency f j=341.
In addition, usually, has regulation sine shown in Figure 18 A or the pulse shape shown in Figure 19 A based on the time series data of measured characteristic value.For this reason, as shown in figure 24, the power spectrum of fundametal component becomes peak value, and overlapping component tends to become the waveform of the size that reduces power spectrum gradually.In addition, in fact, according to the other reasons that is different from the reason that is caused by equipment, the variation of measurement characteristics value takes place, and except that the frequency component corresponding to each equipment, white noise occurs thus.
Converter unit 113 calculates frequency data shown in Figure 24, and the frequency data that calculated are sent to frequency masks unit 114.Then, frequency masks unit 114 is based on the frequency data that receive from converter unit 113, divides expression corresponding to the frequency data (shielding component) of the frequency component of designated equipment be different from the data of frequency data.
That is, frequency masks unit 114 receives the physical device number of the mode of operation that is used for each device fabrication processing and the identification information of each equipment (measuring machine 6, machine table 3 and second processing machine 5) from adjusting control module 115.Then, frequency masks unit 114 is divided corresponding to each equipment based on the information that is received, near frequency data fundametal component and overlapping component, that is, and the frequency data except that the shielding component.That is, the division of frequency data is carried out in frequency masks unit 114 on the frequency component corresponding to machine table 3, second processing machine 5 and measuring machine 6.
In addition, when carrying out the division of frequency data, the characteristic value of being measured by measuring machine 6 comprises measuring error, thus, will be divided into the shielding component together according to the frequency data and the frequency data in its cycle of the frequency of the frequency of number of devices and integral multiple thereof.
Wherein, if by input block 121, during the demonstration indication of the expectation of the shift state of characteristic value after reception improves (S124 is a "Yes"), the frequency data that frequency masks unit 114 will remove the shielding component of being divided send inverse transformation block 119 to.
That is, when receiving the demonstration indication of the state expectation after improving, input block 121 is informed this indication and is adjusted control module 115.When from this notice of input block 121 receptions, adjust the integrated value of control module 115 request frequency screen units 114 transmission corresponding to the power spectrum of the frequency of each equipment.
On the other hand, according to the request that comes self-adjusting control module 115, frequency masks unit 114 is sent to adjustment control module 115 with the integrated value of the power spectrum of each equipment.Therefore, adjusting control module 115 calculates with the standard deviation of the integrated value of the power spectrum of each equipment and the equipment that will have a MSD maximum standard deviation and is appointed as equipment to be adjusted.Then, the information of expression being appointed as the equipment of equipment to be adjusted is sent to frequency masks unit 114.
In the present embodiment, as shown in figure 24, second processing machine 5 is appointed as equipment to be adjusted in the frequency corresponding to second processing machine 5 because the power spectrum that occurs, is adjusted control module 115 greater than the power spectrum that occurs in the frequency corresponding to another equipment.Therefore, adjust control module 115 and will represent that the information of second processing machine is sent to frequency masks unit 114.
When adjusting control module 115 and receive the information of expression equipment to be adjusted, frequency masks unit 114 will be except that corresponding to the frequency data the shielding component of equipment to be adjusted, that is, send inverse transformation block 119 to for the frequency data of " 0 " corresponding to the shielding component of second processing machine 5.
On the other hand, inverse transformation block 119 inverse transformations are 114 frequency data that receive from the frequency masks unit, and based on the frequency data except that shielding component shown in Figure 25, creation-time sequence data (S125).Therefore, inverse transformation block 119 will be shown in Figure 25 A, and the time series data of being created is sent to indicative control unit 120, and indicative control unit 120 shows time series data.
In addition, in the time series data shown in Figure 25 A, can understand with the time series data shown in Figure 23 A and compare, reduce the not quantity of the characteristic value in specialized range.Yet in the time series data shown in Figure 25 A, because the influence of the rising tendency of low frequency component, chart further rises.
For this reason, when with the time series data shown in the histogram table diagrammatic sketch 25A, obtain the shape shown in Figure 25 B.And compare with the situation with Figure 23 B of the time series data of histogram table diagrammatic sketch 23A, more near rectangular shape.In addition, in the variation of the characteristic value that obtains based on the time series data shown in Figure 23 A, the quantity of the characteristic value in specialized range is not far different than the not quantity of the characteristic value in specialized range that obtains based on the time series data shown in Figure 25 A.
Therefore, for carrying out accurate improvement expectation, indicative control unit 120 by the time series data of Figure 23 A, calculates and exports the not quantity of the characteristic value in specialized range with reference to the specialized range information 131 of storage in information memory cell 112.Therefore, the adjusting gear 307 according to present embodiment can accurately obtain before adjustment equipment the quantity of abnormal characteristic value.
In addition, indicative control unit 120 stands the time series data shown in contrary Figure 25 A of FFT with reference to regulation range information 131 by non-shielding component, calculates and export the not quantity of the characteristic value in specialized range.For this reason, the adjusting gear according to present embodiment can obtain after equipment is adjusted the change of the quantity of abnormal characteristic value before and after the quantity of desired abnormal characteristic value and checkout facility are adjusted.
Similarly, in adjusting gear 307, can on indicative control unit 120, show based on the time series data that is different from the frequency data (non-shielding component) that shield component according to present embodiment.In addition, when the equipment of abnormal cause was appointed as in adjustment, adjusting gear 307 can be based on the frequency data of non-shielding component and the time series data of specialized range information 131, and calculating and demonstration be the quantity of the characteristic value in specialized range not.
For this reason, be appointed as the equipment of abnormal cause by adjustment, the user can obtain not what to have increased in the quantity of the characteristic value of specialized range.That is, in example shown in Figure 25, when supposition second processing machine 5 when being abnormal cause, the quantity that can understand the characteristic value in specialized range not reduces to three from initial 7.Therefore, can understand that the user can be by the more processing of high precision execution goods 9 by adjusting second processing machine 5.
Similarly, in adjusting gear 307, before the adjustment of equipment of abnormal cause is appointed as in execution, can find out by adjusting this equipment according to present embodiment, reduce the characteristic value in specialized range not quantity what.For this reason, in view of the throughput rate of goods 9, the user can judge whether to carry out the adjustment of the equipment of being appointed as abnormal cause easily.In addition, even when adjustment equipment, when judgement did not improve significantly, the user can determine not carry out adjustment.
In addition, in adjusting gear 307, demonstration is disclosed by corresponding to the equipment of being appointed as equipment to be adjusted, except that the shielding component, the structure of the time series data that the inverse transformation of the frequency data of non-shielding component generates.In addition, in adjusting gear 307, the time series data that can provide inverse transformation and specialized range information 131 based on the frequency data by non-shielding component to generate shows the not structure of the quantity of the value of the time series data in specialized range.
Yet adjusting gear 307 can have the inverse transformation of demonstration based on the frequency data by non-shielding component, the standard deviation of the value of time series data, rather than the structure of the quantity of the value of the time series data in specialized range not.
Similarly, under the situation of display standard deviation, in adjusting gear 307, can show the variation of the characteristic value when supposition adjustment is appointed as the adjusting gear 307 of abnormal cause.
In addition, in adjusting gear 307, demonstration is disclosed by corresponding to the equipment of being appointed as equipment to be adjusted, except that the shielding component, the structure of the time series data that the inverse transformation of the frequency data of non-shielding component generates.On the contrary, the inverse transformation of the frequency data that for example as shown in figure 26 time series data can be by only shielding component generates and can show.
In addition, as shown in figure 26, transverse axis is a time shaft, and Z-axis is the correcting feature value.In addition, the skew of the characteristic value of the ideal value of correcting feature value representation in specialized range.In Figure 26, only make to change time series data into according near the component inversion the frequency of the quantity of the equipment in the mode of operation of being appointed as equipment to be adjusted.
As mentioned above, when adjusting gear 307 showed sequence data corresponding to the shielding component of the equipment of being appointed as equipment to be adjusted, the user can visually understand the skew by the characteristic value that causes unusually of equipment to be adjusted.That is, under the situation of Figure 26, by per eight one, significant skew in characteristic value, occurs, and skew occurs by one to four ratio.This shows, can find out at least one of eight second processing machines 5, occur unusual.In addition,, can consider fully in two of eight second processing machines 5, occur unusual probably owing to occur changing in one to four ratio.
As mentioned above, by the data that the inverse transformation of exporting the frequency data that only shield component generates, the managerial personnel of line production system 100 can specify has unusual equipment.That is the modes of deflection that, can represent each equipment by high precision according to the line production system 100 of present embodiment.For this reason, in line production system 100, managerial personnel can visually be illustrated in the reason that occurs skew in the characteristic value.
In addition, adjusting gear 307 can show corresponding to other equipment with by adjusting control module 115 and is appointed as the time series data of shielding component of the equipment of equipment to be adjusted.
As mentioned above, when the time series data that shows based on the shielding component of each component, the user is the equipment of the reason of changes of specified characteristic value easily.Therefore, when needs were informed the equipment of being appointed as equipment to be adjusted, the user was by input block 121 input notices.In addition, similarly, when specifying the equipment of equipment to be adjusted, can ignore by the specification of the equipment of adjusting control module 115 adjustment and handle by the user.For this reason, further simplify the structure of adjusting control module 115.
(adjustment of equipment is handled)
Then, will describe by adjusting gear, be appointed as the adjustment of the equipment of abnormal cause and handle with reference to Figure 27 according to present embodiment.
In addition, obtain time sequence data,, and frequency data are divided into shielding component and other processing (among Figure 27 by time series data calculated rate data, step S131 is to step S133) identical with the step S121 to S123 of Figure 22, the descriptions thereof are omitted thus.
In step S134, if when input block 121 receives the indication (being ' being ' among the S134) of the meaning of adjustment equipment, adjust control module 115 indication measurement machine setup units 116, processing machine setup unit 117 and door setup unit 118 and carry out the equipment of being appointed as equipment to be adjusted of adjusting.Then, according to the indication that comes self-adjusting control module 115, the adjustment (S135) of measuring machine setup unit 116, processing machine setup unit 117 or door setup unit 118 actuating equipments.
That is, when execution indication that the adjustment of receiving equipment is handled, input block 121 is informed this indication and is adjusted control module 115.When receiving this indication, adjust the integrated value of control module 115 request frequency screen units 114 transmission corresponding to the power spectrum of the frequency of each equipment.
On the other hand, frequency masks unit 114 is according to the request that comes self-adjusting control module 115, and transmission is corresponding to the integrated value of the power spectrum of the frequency of each equipment.Then, adjust the integrated value of control module 115 by the power spectrum of each equipment, basis of calculation deviation, and the equipment that will have a MSD maximum standard deviation is appointed as equipment to be adjusted.
Wherein, suppose that adjusting control module 115 is appointed as equipment to be adjusted with second processing machine 5.In this case, adjust one the operation that control module 115 indication processing machine setup units 117 disconnect the second processing machine 5a to 5h.
In addition, adjust control module 115 control travelling belts 8 so that make goods 9 not be placed to second processing machine 5 in the off-position.In addition,, for example, change the transfer rate of the goods 8 of travelling belt 8, or between the turntable 4 and second processing machine, provide a plurality of and the open/close state of control gate shown in Figure 29 about the control of travelling belt 8.That is, as mentioned above, by using the testing result of sensor, the ON/OFF of control gate.
As mentioned above, if any one of the second processing machine 5a to 5h is arranged to outage, and the quantity that changes second processing machine 5 in mode of operation, with reference to the time delay 130 of storage in information memory cell 121, processing machine setup unit 117 is sent to data acquisition unit 111 simultaneously by processing machine setup unit 117 with commencing signal, makes the setting changing concluding time postpone this time delay 130.
When from processing machine setup unit 117 reception commencing signals, data acquisition unit 111 turns back to step S131 so that predetermined a plurality of characteristic values and the creation-time sequence data that obtains to be measured by measuring machine 6 once more.Therefore, repeat processing from step S131 to step S133.Therefore, by adjusting control module 115, carry out the relevant judgement of whether carrying out the judgement of the equipment from second time execution in step S134.
Promptly, from the frequency data that the frequency conversion by the time series data created based on the characteristic value that obtains after the equipment adjustment obtains, adjust control module 115 from the frequency masks unit 114 integrated values that receive corresponding to the power spectrum of second processing machine 5 of being appointed as equipment to be adjusted.Then, based on the integrated value of the power spectrum that is received, adjust the standard deviation that control module 115 calculates second processing machine 5 of being appointed as equipment to be adjusted.Then, adjust control module 115 and judge whether the size of the standard deviation that is calculated is equal to or less than predetermined value.In addition, predetermined value can be passed through input block 121, is provided or can be stored in advance in the information memory cell 121 by the user.
Then, when the size of criterion deviation is equal to or greater than predetermined value, adjusts control module 115 judgements and require the equipment adjustment and proceed to step S135.Then, adjust control module 115 indication processing machine setup units 117 and connect second processing machine 5 and the second independent processing machine 5 that cuts off the power supply that is in the off-state in advance.Then, according to the indication that comes self-adjusting control module 115, processing machine setup unit 117 energising in preceding off-position second processing machine 5 and outage from the second independent processing machine 5 of second processing machine 5.
In addition, in this time, adjust control module 115 control travelling belts 8 and transmit goods 9 and be not placed to second processing machine in the off-position so that make.
Then, process enters step S136, and the time delay 130 of storage in the reference information storage unit 112, processing machine setup unit 117 is sent to commencing signal data acquisition unit 111 once more simultaneously by processing machine setup unit 117, by the interval of time delay 130, postpone the setting changing concluding time.In addition, repeat to be equal to or less than setting up to the size of adjusting control module 115 criterion deviation among step S134 from the processing of step S131.
In addition, in the foregoing description, describe the situation that equipment to be adjusted is second processing machine 5, still, when equipment to be adjusted is machine table 3 or measuring machine 6, carried out identical processing.In addition, when equipment to be adjusted is machine table 3,,, can realize the change of the user mode of machine table 3, handle identical with the adjustment of the said equipment quantity by the ON/OFF of control gate 2 according to indication from door setup unit 118.
That is,, in above-mentioned line production system 100, identity marking number (ID number) is distributed to each machine table 3a to 3p or pass through to use rotary encoder, the departure of the rotation of management turntable 4 for specifying any machine table 3.
Then, when by distributing to ID number of each machine table 3a to 3p, when monitoring the position of machine table 3, adjusting gear 307 is connected to the ON/OFF of door 2 rotation of turntable 4.For example for goods 9 are not contained among the machine table 3a with identification number (1) of distributing to it, the time of control gate 2 when the goods 9 that transmitted by travelling belt 8 are contained among the machine table 3a closes.Similarly, by control turntable 4 and door 2, can control goods 9 and not be contained in the machine table 3 that is in non-operating state.
In addition, as mentioned above, be contained in the machine table 3, can adjust to reduce the variation of characteristic value by restriction goods 9.In addition, when changing the quantity of machine table 3 in the mode of operation in this way, can only realize by the ON/OFF of control gate 2 and the rotation of turntable 4.Therefore, in line production system 100, be easy to carry out and adjust so that reduce the variation of characteristic value.
In addition, when equipment to be adjusted was measuring machine 6, from the on/off indication of the power supply of measuring machine setup unit 116 and the detection of door 200 and sensor 201, the ON/OFF of control gate 200 can realize the change of the user mode of measuring machine 6 by basis.
In addition, when equipment to be adjusted was measuring machine 6, adjusting gear 307 had the ON/OFF control by the power supply of measuring machine 6, reduced the variation of characteristic value so that drop on the interior structure of specialized range.Yet,, for example, can carry out and adjust so that reduce the variation of characteristic value by making goods 9 not be placed on the measuring position of specified measurement machine 6 by the ON/OFF sequential of control gate 200 and the measuring position that changes goods 9.
As mentioned above, by the on of the power supply of second processing machine 5 and measuring machine 6 and the ON/OFF control of door 2, control has unusual equipment and is not used in equipment as equipment to be adjusted according to the adjusting gear 307 of present embodiment.Therefore, adjusting gear 307 controls have unusual equipment, thereby reduce the variation that occurs in the characteristic value of fabricated product 9.
That is, specify according to the adjusting gear 307 of present embodiment to become generation and significantly depart from the equipment of main body of characteristic value of specialized range and the mode of operation that changes relevant device, depart from the specialized range value so that can reduce characteristic value.For this reason, adjusting gear 307 can improve the quality of goods 9 to be processed after processing.
In addition, as mentioned above, adjusting gear does not require each to second processing machine 5, machine table 3 and measuring machine 6, special-purpose adjustment unit and the structure that repeats trickle adjustment are provided, and carry out simple control, thereby reduce departing from of characteristic value and specialized range value so that connect and cut off the power supply of the device of positive justification.
In addition, the adjusting gear 307 according to present embodiment can have by it is related with the improvement prediction processing structure that the adjustment of execution said apparatus is handled.By with it with to improve prediction processing related, carry out under the situation of adjustment processing of said apparatus, behind step S126, execution in step S134.In addition, if carry out step S136 shown in Figure 27, process turns back to step S121 shown in Figure 22.
In addition, in step S134, if owing to be appointed as equipment unusual of equipment to be adjusted, the side-play amount of characteristic value (the standard deviation degree of characteristic value) is equal to or less than predetermined value, the adjustment of carrying out this equipment is continuously handled till adjusting control module and determining it.
Yet the example of the condition of finishing that the adjustment of this device is handled can comprise the peaked structure of use corresponding to the power spectrum of the frequency of the equipment of being appointed as equipment to be adjusted.In addition, because following reason, use the maximal value of power spectrum, determine to adjust whether necessary handle structure highly beneficial.That is, for example, in removing the equipment that has become the adjustment main body,, do not influence the maximal value of using power spectrum, carry out the skew of other characteristic values in definite structure even when the factor that departs from that generates other characteristic values.
In addition, in adjusting gear 307 according to present embodiment, in " improvement prediction processing " and " adjustment of equipment is handled ", adjust control module 115 by integrated value corresponding to the power spectrum of the frequency of each equipment, basis of calculation deviation, and the equipment that will have a MSD maximum standard deviation is appointed as main body to be adjusted.
Yet, specify the method for main body to be adjusted to be not limited thereto, but can have following structure.
Adjust control module 115 receptions by the time series data of the characteristic value of data acquisition unit 111 establishments and based on the time series data that is received, basis of calculation deviation.Adjust control module 115 and can specify the equipment that becomes abnormal factors based on the side-play amount of the standard deviation that calculates with this method.
Become in appointment under the situation of structure of equipment of abnormal factors,, finish the adjustment of equipment and handle according to following condition.That is, in being appointed as the equipment of abnormal factors, when changing operating equipment and being equal to or greater than predetermined value, adjusting control module 115 and finish the adjustment of equipment and handle based on the standard deviation of the time series data that receives from data acquisition unit 111.According to this structure,, can reduce the operational ton in the adjusting gear 307 owing to need not carry out FFT with respect to the time series data of creating by data acquisition unit 111.
In addition, can receive contrary FFTs corresponding to each device from inverse transformation block 119, the time series data of the shielding component of the frequency of the quantity of machine to be operated, and can specify and adjust control module 115 out of order devices.
Similarly, based on contrary FFT time series data, specify under the situation of structure of the device that trouble is arranged, under the following conditions, the adjustment of finishing device is handled.That is, when the variation of the characteristic value of contrary FFT time series data during less than predetermined value, or when the quantity greater than the characteristic value of predetermined value is lower than predetermined quantity, the adjustment process of end equipment.
