Definitions

  • the invention relates to a device for attaching reinforcements to register inserts.
  • a device is known from US Pat. No. 4,588,463 for producing folded storage folders, which is provided on one narrow side with reinforced tabs.
  • the known machine is supplied with the base material for the filing folder from an endless roll, the web width being somewhat greater than the height of the finished filing folder, measured in the direction parallel to its folded back.
  • the continuously funded train is provided with an adhesive along one edge in a strip located on the top, while on the underside, opposite the strip, a plastic adhesive tape is applied, the width of which is more than twice as large as the depth of the tab created later.
  • the edge of the endless web provided with the reinforcement strip is turned upward by the machine, so that where the adhesive layer is provided, a double-layer arrangement is formed which carries along its outside the reinforcement tape which runs in the longitudinal direction of the web.
  • the machine cuts the tape where it is double-ply according to the tabs to be produced, to a depth that is less than the depth of the folded reinforcing bottom.
  • the finished folder therefore not only has the reinforcement in the area of the tab, i.e. at the point that is more exposed to wear, but there is reinforcement everywhere along the edge that carries the tab, which may be cut out.
  • This type of reinforcement for the folder requires a high consumption of film for the reinforcement, which is particularly uneconomical because a large part is cut away again after the reinforcement film has been attached. As a result, there is also a large amount of waste which, even if the base material for the folder consists of easily rotten paper, has a very high proportion of plastic and is accordingly difficult to dispose of.
  • the positioning of the reinforcement on the register insert in connection with pushing the reinforcement as far as possible onto the tabs is improved if the groove in the gripper has a V-shaped shape.
  • evasive movements are largely avoided, which could otherwise lead to play or a gap between the edge of the reinforcement and the edge of the register insert.
  • the reinforcement can be held in the groove of the gripper solely by means of its return force if projections to be pointed towards one another are provided on the two edges of the groove.
  • the longitudinally folded reinforcement is pressed against the walls of the groove due to its return force, while its movement out of the groove is stopped by the projections. As a result, it sits in a form-fitting manner in the groove of the gripper and cannot fall out when the gripper swivels.
  • the introduction of the reinforcement into the gripper is simplified by a slide which is displaceably guided opposite the groove in the area of the loading position.
  • the pre-folded reinforcement need not be pushed into the groove from the side, but is pushed into the groove from the front by means of the slider. This reliably prevents the reinforcement from striking the edges of the gripper.
  • the arrangement of the cutting device is simplified if the reinforcements are cut down from a strip coming from a supply reel.
  • the movement of the slider can be easily synchronized with the movement of the knife in that the slider is attached to the knife itself. This reliably prevents the reinforcement cut from the strip from falling off, in particular if the strip is only finally severed after the reinforcement has already been partially inserted at least into the groove of the gripper.
  • a device is located upstream, based on the transport movement of the strip for the reinforcements, which folds or folds the strip once in the longitudinal direction parallel to its two edges.
  • the cutting device is preferably provided with a die which has a correspondingly triangular shape Includes opening, the tip of which is directed to the groove, while the knife of the cutting device has a similar shape and the tip of the knife has the same orientation.
  • the cutting movement of the knife is a sliding movement directed towards the groove.
  • the gripper is designed as a drum which contains several equidistantly distributed grooves in its circumference, the longitudinal extent of which is parallel to the axis of rotation.
  • a drum rotation corresponding to the azimuth angle between two adjacent grooves is sufficient.
  • a further, previously emptied groove is brought into the loading position and can accommodate a new reinforcement.
  • a stapling device is provided so that the reinforcements after the transfer to the register insert are non-displaceably connected to the register insert until they are finally glued or welded.
  • this stapling device even longer reinforcements can be reliably provisionally fixed, if the stapling device has two sets of aligned tines which can be inserted into correspondingly arranged, circumferential grooves of the drum-like gripper. These grooves cut the V-shaped grooves for the reinforcements and allow the tines to temporarily connect the reinforcement to the stitching insert in several places.
  • the reinforcement to be attached to the register insert can be accommodated completely in the drum and does not have to project on one of the end faces of the drum.
  • an incompletely cut register insert 1 is illustrated, which consists of a rectangular cut sheet of paper or a sheet of thin cardboard.
  • the register insert 1 carries a continuous reinforcement strip 4 in order to protect a perforation 5 located in the vicinity of the rear edge 3.
  • the register insert 1 will have a tab 7 in the area of its front edge 6, which protrudes laterally from the front edge.
  • the register insert is cut out along dashed lines 7 and 8.
  • the tab 7 then protruding from the front edge 6 bears letters, numbers or other symbols in accordance with the desired sorting scheme - in the illustrated example it is the register insert with the letter B from an alphabetically marked sentence.
  • a reinforcement 9 is attached to the front edge 6, which is folded and on both the front and the back of the blank 2 is glued or welded on.
  • the reinforcement 9 envelops the free front edge of the tab 7 in one piece and, as can be seen in FIG. 1, extends upwards and downwards beyond the tab 7 so that it is cut out accordingly along the lines 7 and 8.
  • the position of the tab 7 on the front edge 6 is arranged as a function of the printed symbol, ie the distance of the tab from the upper edge of the register insert 1 is different. Accordingly The reinforcement 9 moves along the front edge 6 in order to minimize the material loss when cutting out along the lines 7 and 8, and on the other hand always to protect the tab 7.
  • the device 11 shown in a highly schematic manner in FIG. 2 is provided.
  • the natural parts such as bearings, frames and the like. are omitted for the sake of clarity so as not to overload the drawing with details which are not necessary for understanding the structure and mode of operation of the device 11.
  • the device 11 essentially consists of a transport device 12 for transporting the blanks 2, a feed device 13 with which the reinforcements 9 are transferred to the register insert 1, a cutting device 14 which serves to cut the reinforcements 9 off a supply strip 15, and a stitching device 16 to temporarily attach the reinforcements 9 to the respective register insert 2.
  • the correct position of the register insert 2 is set with the aid of a stop device 17, the structure of which can be seen in detail in FIGS. 5 and 6.
  • the transport device 12 contains two parallel roller-shaped deflecting rollers, of which only the roller 18, which is located upstream in relation to the path of the register inserts 2, is visible for reasons of illustration.
  • the deflection roller 18 is coupled to a drive device 19, by means of which it can optionally be set in revolutions. Guide around the two guide rollers 18 two endless conveyor belts around, the register inserts 1 are transported by frictional entrainment on the working run above.
  • the working span of the two transport belts 21 defines the path along which the register inserts 1 are transported.
  • the feed device 13 is arranged.
  • This contains a cylindrical drum 22 which is rotatably mounted about its longitudinal axis 23. It serves as a gripper for the reinforcements 9 in order to transfer them into the path of the register inserts 1.
  • Its axis of rotation 23 runs parallel to the working run of the two transport belts 21 and thus parallel to the path along which the register inserts 1 are transported past or through the feed device 13.
  • the cylindrical drum 22 has two mutually parallel end faces 24 and 25 and a cylindrical outer peripheral surface 26, in which a total of six V-shaped grooves 27 are contained in the exemplary embodiment shown.
  • the grooves 27 pass through both end faces 25 and their otherwise flat side walls 28 and 29 diverge to the outer circumferential surface 26, namely they run at the same angle in each case with respect to a radius which leads through the intersection line of the two side walls 28, 29 of the respective groove 27.
  • the drum 22 is rotatably mounted in a stationary manner and is coupled via a shaft 31 to a stepper motor drive 32, by means of which the drum 22 can be rotated and stopped in a controlled manner by the angular distance between two adjacent grooves 27. Because of the equidistant distribution of the grooves 27 along the circumference of the drum 22, this angle of rotation from groove to groove is the same in each case.
  • the grooves 27 have the same cross-sectional shape over their entire length, which is why their edges 33 and 34 run parallel and at a distance from one another. As can be seen in particular in FIG. 3, each of the grooves 27 is provided on its two edges 33 and 34 with strip-shaped projections 35, 36 which rise slightly from the associated wall 28 and 29 and pass over the entire length of the groove 27.
  • the elevations 35, 36 have the purpose of holding the reinforcement 9 inserted into the groove 27 in the manner explained later.
  • the cutting device 14 contains a die 37 which is arranged next to the upstream end face 25 and whose flat-ground cutting surface 39 extends parallel to the end face 25. 4, there is a triangular opening 38, which has a similar shape to the grooves 27, but, compared to these, a smaller opening angle, as best shown in FIG.
  • the opening 38 is aligned in the corresponding position of the drum 22 with a respective groove 27, but has a somewhat greater radial distance from the axis of rotation 23 than the groove 27 aligned with it, so that the strip 15 passing therethrough unimpeded into the one aligned with it Groove 27 can be inserted from the side.
  • a cutting knife 41 which is formed on a slide 42, slides back and forth on the flat-ground surface 39 of the cutting die 37.
  • the cutting knife 41 has a cross-sectional shape corresponding to the base area of the opening 38, the tip of the cutting knife 41 and the tip of the opening 38 pointing in the direction of the axis of rotation 23.
  • a push rod 43 is connected, which is guided in a longitudinally displaceable manner in a bushing 44.
  • the displacement movement is perpendicular to the axis of rotation 23.
  • a toggle lever arrangement 45 comprising two levers 46 and 47 is connected to the rear end of the cylindrical push rod 43.
  • the lever 47 is pivotably supported in a fixed axis 48, while a piston rod 51 of a working cylinder 52 is articulated on a connecting joint 49, which connects the two levers 46 and 47 of the toggle lever arrangement 45 to one another.
  • the direction of movement of the piston rod 51 is perpendicular to the displacement movement of the push rod 43, so that a downward movement of the piston rod 51 leads to a stretching of the toggle lever arrangement 45, whereby the knife 41 is advanced in the direction of the axis of rotation 23.
  • a section is cut down from the strip 15, the length of which corresponds to the length of the required reinforcement 9.
  • the strip 15 moves in direct current to the register inserts 1.
  • a folding station 54 is provided for the strip 15, which serves to strip the strip-shaped strip 15 coming from a supply spool, not shown, which is deflected by a deflection roller 55 and from a subsequent guide device 56 is kept plan to fold once in the longitudinal direction.
  • the folding station contains the folding station a folding block 57, through which the two edges of the strip 15 are moved towards each other, and two pinch rollers 58, between which the pre-folded strip 15 runs.
  • At least one of the two squeezing rollers 58 is to be set in a controlled manner by means of a drive (not shown) in rotation in order to advance the folded strip 15 through the opening 38 of the cutting die 37.
  • the folded strip 15 jumps open slightly in the area between the two pinch rollers 58 and the cutting device 15, so that, as can be seen in FIG. 4, the knife 41 between the two leg of the strip 15 created by the folding can penetrate.
  • each leg of the strip 15 is cut off for itself, while on the other hand the strip 15 inevitably opens due to the cutting movement.
  • the resulting cut burr points outward on both legs of the strip 15 and does not hinder the opening of the section cut off from the strip 15 and forming the reinforcement 9.
  • the stapling device 16 contains a lower pivotably mounted arm 61, the pivot axis of which runs parallel to the axis of rotation 23. At the free end of the arm 61, a bar 62 is attached, which runs parallel to the axis of rotation 23 and on its top a large number, in the embodiment shown carries a total of five, narrow tines 63. All tines 63 have at their end remote from the beam 62 a flat pressure surface 64, which are all at the same height.
  • Another set of tines 65 which are fastened to a bar 66 located above the drum 22, is aligned with the tines 63.
  • the bar 66 extends parallel at a distance from the bar 62 and is seated on its own swivel arm 67, which in turn is mounted so as to be pivotable about a swivel axis parallel to the axis of rotation 23.
  • the tines 65 have a similar shape to the tines 63 and also have flat pressure surfaces 68 which are at the same height.
  • the drum 22 contains circumferential grooves 69 which correspond in number to the number of tines 63 and 65 and are in alignment therewith.
  • the grooves 69 penetrate or cut all the grooves 27 on the circumference 26 of the drum 22.
  • the two arms 61 and 67 can be pivoted towards one another by means of a drive device (not shown further), which leads to the two sets of tines 63, 65 in immerse the grooves 69 on the side of the drum 22 which is adjacent to the transport device 12.
  • the stop device 17 serves to stop the register insert 1 to be provided with the reinforcement 9 with respect to the longitudinal extension of the drum 22 in such a way that the tab 7 or the area forming the tab 7 after the final cutting with an in the corresponding groove 27 lying reinforcement 9 is aligned. Since all of the register inserts 1 that belong to a complete set are generated in immediate succession with the described device 11, the stop device 17 must be adjustable in the transport direction, because with two immediately successive register inserts 1 the associated tab 7 has a different position on the front edge 6 of the Blank 2 has. For example, if a complete set of register inserts 1 contains the letters of the alphabet in their conventional order, the register insert 1 is first provided with the letter "Z" with a reinforcement.
  • the stop device 17 must have a position which ensures that the tab 7 located in the vicinity of the lower edge of the blank 2 is aligned with the reinforcement 9 provided in the groove 27 of the drum 22.
  • the tab 7 with the letter "Y" will be offset a little further towards the upper edge of the blank 2, which is why the stop device 17 must be adjusted a little further downstream in accordance with the offset of the tabs 7 in adjacent register inserts 1.
  • stop device 17 The structure of the stop device 17 is explained in detail below with reference to FIGS. 5 and 6.
  • a cylindrical guide rail 72 extends on the upper side between the two carriers 71, on which a slide 74 is guided parallel to the axis of rotation 23 without play with a ball guide bushing 73.
  • the carriage 74 is secured against rotation on the guide rail 72 by means of a pin (not shown further) which engages in a longitudinal groove of the guide rail 72.
  • Two brackets 76 fastened to it by screws 75 protrude on both sides and are connected to one another at the upper free end by a yoke 77.
  • a working cylinder 78 is fastened, the piston rod 79 of which can be adjusted back and forth vertically and therefore at right angles to the axis of rotation 23.
  • the free end of the piston rod 79 carries a beam 81 on which several stop bolts 82, in the exemplary embodiment shown a total of four, are fastened so as to protrude upwards.
  • the stop bolts 82 sit in a row that is perpendicular to the transport movement of the register inserts 1 on the transport device 12.
  • Two pins 83 projecting downward from the beam 81 and running on both sides of the piston rod 79 slide in bores in the yoke 77 and serve to prevent rotation for the beam 81 in order to maintain its right-angled position with respect to the transport direction of the register inserts 1.
  • a reinforcing strut 84 extends below the guide rail 72 and is screwed to the two supports 71 at the end. It also serves the Attachment of an inductive proximity switch 90, which is shown exclusively in FIG. 6 and notifies a central control of the device 11, which is not illustrated, when the slide 74 has assumed a defined position along the guide rail 72.
  • a bearing block 85 is seated on one of the carriers 71, in which a drive shaft 87 is rotatably mounted by means of two roller bearings 86.
  • the bearing block 85 is located below the reinforcing strut 84.
  • a toothed belt pulley 88 is connected in a rotationally fixed manner to the drive shaft 87, around which a toothed belt runs, which is not shown for the sake of clarity and which is firmly connected to the slide 74.
  • the deflection devices necessary for this in the area of the two supports 71 are likewise omitted for the sake of clarity.
  • stepper motor 89 Flanged to the side next to the bearing block 85 is a stepper motor 89, the output shaft 91 of which is connected to the shaft 87 via a compensating coupling 92.
  • the stepper motor 89 like the bearing block 85, is only shown in FIG. 6.
  • the device 11 described so far operates as follows, assuming that the drum 22 has the position shown in FIG. 2 and a reinforcement 9 is inserted in the groove 27 which points directly in the direction of the transport device 12. In this position, the drum 22 is held by the associated drive device 32. With the help of the transport device 12, a blank 2 can be transported onto the transport belt 21 by starting the drive device 19, in such a way that its front edge 6 is moved parallel to the axis of rotation 23 through the corresponding groove 27. The transport movement of the blank 2 is stopped as soon as it hits the stop bolt 82 of the stop device 17 with its lower edge. In this position, the area on the front edge 6 of the blank 2 in which the printing of the tab 7 is located is aligned with the reinforcement 9 located in this groove. The immersion of the front edge 6 in the groove 27, which has the reinforcement contained therein, 3 shows a front view.
  • the drive devices for pivoting the two arms 61 and 67 of the stitching device 16 are started.
  • the bars 62 and 66 with the two sets of tines 63, 65 are moved towards one another, immersing them in the circumferential grooves 69 from above and below. They simultaneously touch the V-shaped reinforcement 9 located in the groove 27 and press them with the help of their pressure surfaces 64, 68 at several points against the front and the back of the blank 2.
  • Each pressure surface 64 acts as an anvil for the corresponding other pressure surface 68 or vice versa.
  • the resulting pressing force causes the reinforcement 9 to be attached to the front and rear of the blank 2 at several points 92, as shown in a highly schematic manner in FIG. 7.
  • the type of attachment depends on how the corresponding back of the reinforcement 9 or the strip 15 is equipped.
  • a heat-activated adhesive is preferably used here, which is why the tines 63 and 65 are heated.
  • the two pivot arms 61 and 67 are moved away from one another again, which causes the prongs 63 and 65 to emerge from the grooves 69.
  • the pressure medium cylinder 78 is actuated, namely its cylinder chamber on the piston rod side is pressurized with a pressure fluid.
  • the piston rod 79 moves into the pressure medium cylinder and pulls the stop pins 82 below the plane defined by the two transport belts 21.
  • the stop pins 82 thus come out of the path of the blank 2, which is moved out of the groove 27 of the drum 22 when the transport device 12 is started.
  • the corresponding groove 27 While a reinforcement was transferred from the corresponding groove 27 to the blank 2 on one side of the drum, the corresponding groove 27 is loaded with a new reinforcement 9 on the diametrically opposite side. It can therefore be said that one of the grooves 27 is in the transfer position, while another groove 27, which faces the slide 53, is in the loading position.
  • the loading of the groove 27 assumed to be empty for the description takes place in that the pinch rollers 58 are set in rotation by the central control. In this way, on the one hand, new strip 15 is pulled off the supply roll and continuously folded in the folding station 54, while the V-shaped strip 15 is pushed by the pressure rolls 58 through the opening 38 in the die 37.
  • the strip 15 is strongly folded by the two pinch rollers 58, it still has a certain tendency to jump open, which is why it rests on the edges of the opening 38 with its two legs formed by the folding becomes. At the same time, the fold provides stability against buckling and can be easily pushed forward in the horizontal direction. Since the opening 38 is at a greater radial distance from the horizontally running axis of rotation 23 than the respective groove 27, the strip 15 can easily be inserted into the corresponding groove 27 or be placed in front of it.
  • the slider 53 seated thereon which is wedge-shaped in cross section, is also moved towards the groove 27.
  • the section of the strip 15 which projects beyond the die 37 is gripped by the slide 53 and is forcibly pressed into the groove 27.
  • the end of the advancing movement of the knife 41 or of the slider 53 is only present when the edge of the slider 53 adjacent to the drum 22 abuts almost on the base of the groove 27. In this position, the edges of the section which has now been completely cut off from the strip 15 and which now forms the reinforcement 9 have passed the ridges 36 and 37.
  • the V-shaped reinforcement 9 jumps due to its inherent elasticity a little further and their edges will catch behind the ridges 35, 36 when the slide 53 retracts, when the pressure cylinder 52 is filled in the opposite direction.
  • the width of the strip 15 before folding in the folding station 54 must be smaller or at most as large as the shortest path through the groove 27 along its two walls 28, 29, ie as long as the sum of those in the plan view 3 recognizable lines, which represent the side walls 28 and 29 of a groove 27.
  • the reinforcement 9 is thus caught in the groove 27 in question and can only be removed in the direction of the slot of the groove 27 if it is compressed accordingly.
  • an initially empty groove 27 is loaded with a new reinforcement 9, while on the other hand coinciding with this cycle, as described above, on the opposite side of the drum 22 one beforehand the reinforcement 9 located in the groove 27 has been attached to the corresponding blank 2 and has been removed from the groove 27 by the further movement of the blank 2.
  • the grooves 27 running on the visible top of the drum 22 are empty, i.e. they contain no reinforcements 9, while the grooves 27 migrating on the underside contain reinforcements 9, that is to say they are filled.
  • the stop device 17 In addition to advancing the drum 22 by a groove 27, the stop device 17 must also be adjusted, since with successive cuts 2 the tab 7 has a different position along the front edge 6.
  • the stepper motor 89 is stopped.
  • the carriage 74 stops and the pressure medium cylinder 78 is started in the sense of an upward movement of the beam 81.
  • the stop pins 82 come into the path of movement of the blanks 2.
  • the transport device 12 can now be switched on in order to bring the next blank, from which the subsequent register insert 1 is to be made, into the feed device 13.
  • the blank 2 is held in the correct position in the sense that its area which later forms the tab 7 is aligned with the reinforcement 9 provided in the drum 22, with which the device 11 has assumed the same state as at the beginning of the explanation of its function.
