Description
CA 022438~3 l998-07-2l TITLE: Braking arrangement for dispensers of continuous material TECHNICAL FIELD:
The present invention relates to a braking arrangement for use in connection with dispensers of continuous material such as paper. The invention further relates to a dispenser equipped with such a braking arrangement.
BACKGROUND OF THE INVENTION:
Paper may ~e dispensed from dispensers predominantly in ~5 three main ways. Firstly, the paper may be in the form of individual sheets of predetermined size which are arranged within the dispenser such that the removal of one sheet causes a portion of a subsequent sheet to be exposed ready for removal. Secondly, the paper may be in the form of a continuous sheet and the dispenser is provided with a serrated or sharpened edge against which the sheet is brought to sever a certain length from the sheet. Thirdly, the paper may be in the form of a continuous sheet with perforations to allow a predetermined length of the sheet to be torn from the remainder of the sheet along the perforations. The feeding of the paper from these three types of paper may be manually or automatically achieved.
The present invention is primarily concerned with the 3Q manual dispensing of perforated paper from a dispenser, though it is to be understood that the invention may also be applied to dispensers of the second type described above.
In a known dispenser of perforated paper, the paper is in the form of a roll having a longitudinal axis. The paper is I CA 022438~3 1998-07-21 W O 97/26818 PCT/SE97/00~55 arranged in the dispenser such that the paper is unwound from the ;centre of the roll in a vertically downward direction through a dispensing nozzle. The dispensing nozzle is in the form of a truncated cone. As the paper passes through the nozzle, a braking force on the paper builds up due to friction between the sheet of paper and the inner surface of the nozzle. Provided that this braking force is sufficiently high, once a perforated length of the sheet of paper has passed through the nozzle, the weakening in the continuous sheet along the perforations will result in a length of the continuous sheet being torn from the remainder of the sheet.
Although the above-described dispenser has enjoyed commercial success, it does suffer from several disadvantages. Firstly, the braking force which is generated by the passage of the paper through the dispensing nozzle is very much dependent on the grade of paper being dispensed. Accordingly, the dispensing nozzle must be provided with an opening of variable size to thereby vary the braking force in order for the dispenser to be able to function with paper of different grade.
Secondly, when the dispenser is charged with a new roll, the free end of the roll must be pushed through the nozzle to expose a length of sheet sufficiently long to allow it to be gripped. Since, in order to generate the requisite braking force, the nozzle is relatively long and narrow, difficulti!es arise in passing the free end of the roll through thle nozzle.
SUM~RY OF THE lNV~N'l'lON:
It is therefore an object of the present invention to provide a braking arrangement for use in dispensers of continuous material which overcomes the disadvantages identified above.
CA 022438~3 1998-07-21 This ob~ect is achieved by a braking arrangement according to claim 1.
Since in accordance with the present invention, the sheet of material is passed between a pair of parallel, partially intermeshing gearwheels, the level of the braking force which is generated is much less dependent on the grade of material of the sheet.
It is a further object of the present invention to provide a dispenser for dispensing a continuous paper sheet, which dispenser overcomes the disadvantages associated with previous continuous paper sheet dispensers.
This object is achieved by a dispenser according to claim 9.
Advantageous embodiments of the braking arrangement and dispenser according to the present invention are detailed in the respective dependent claims.

DE~ATr.F.~ ~ESCRIPTION OF PREFERRED EMBODIMENTS:
In the drawings, reference numeral 10 generally denotes a braking arrangement according to the present invention. The braking arrangement 10 is intended primarily for use with dispensers of continuous material, particularly paper dispensers,. In accordance with the present invention, the braking arrangement 10 comprises a first gearwheel 12 which is arranged for rotation about a first axis 14.
Advantageously, the first gearwheel 12 is keyed to a spindle 16 which in turn is journalled for rotation in a -chassis 18. The chassis 18 is intended to be mounted to a dispenser, e.g. a paper dispenser, and is provided with a generally conical shaped dispensing nozzle 19 through which the contents of the dispenser 20 (Fig. 2) can be dispensed.
As is most clearly apparent from Fig. 1, the chassis 18 comprises a pair of spaced flanges 21 which support the spindle 16 to thereby allow the first gearwheel 12 to rotate between the spaced flanges 21 at a fixed position beneath the dispensing nozzle 19.
In accordance with the present invention, the braking arrangement 10 further comprises a second gearwheel 22 which is arranged for rotation about a second axis 24. The second gearwheel 22 is arranged for displacement relative to the first gearwheel 12 such that the second axis 24 always r~mA;n~ parallel to the first axis 14. Irrespective of the position of the second gearwheel relative the first gearwheel, the first axis 14 is always above the second axis 24, i.e. closer to the top of the chassis as shown in CA 022438~3 1998-07-21 the drawings. Furthermore, and as is most clearly apparent from Fig. 3, the second gearwheel 22 is biased towards the first gearwheel 12 to partially intermesh therewith such that a variable gap 26 is defined between the first and second gearwheel for passage of the continuous material.
Advantageously, and as shown in the drawings, in order to permit the second gearwheel 22 to be displaceable relative the first gearwheel 12, the second gearwheel is keyed to a spindle 28 which in turn is carried by a generally U-shaped cradle 30 in such a manner that the second gearwheel may rotate between the arms of the U-shaped cradle. As is clearly shown in Fig. 3, the cradle 30 is journalled to the chassis 18 at support locations 31 such that the first and second gearwheels 12, 22 may partially intermesh. lt is further apparent from Fig. 3 that the cradle 30 is acted upon by a spring force generated by a spring 32 mounted on the chassis 18 to thereby bias the cradle, and thus also the second gearwheel, towards said first gearwheel 12. In order to ensure that the first and second axes 14, 24 remain parallel, the spring 32 is advantageously arranged to act on a region of the cradle 30 which is substantially equidistant from the support locations 31 when the cradle is ~ournalled to the cradle on the chassis.
To prevent the spring from completely closing the variable gap 26 between the gearwheels, thereby h;n~ering the passage of continuous material 20, the bra~ing arrangement is suitably provided with (not shown) stop means, such as interacting surfaces on the cradle 30 and the chassis 18 or spacer discs carried on the spindles 16 and 28, which , contact each other when a predetermined m; nimllm gap is reached. Naturally, this predetermined m; n;mllm gap may be made adjustable by suitable means, such as interchangeable spacer discs.
CA 022438~3 l998-07-2l To enable the braking arrangement to be used with different types of dispenser containing different materials, the force generated by the spring 32 is preferably adjustable.
Adjustment may be achieved in any conventional manner, for example by the provision of an adjustment screw 34 carried by the chassis 18, which screw can be rotated to compress or expand the spring.
As will be apparent from Fig. 1, the first gearwheel 12 may be arranged to cooperate with a manually actuable feed wheel 36 which may be used to rotate the first gearwheel to aid in the initial through feed of material when e.g. the dispenser is provided with a new roll of paper. Naturally, the braking arrangement lO may, if desired, be provided with an automatic feeding means, for example an electric motor, to rotate the gearwheels.
Tests have shown that, when operated in conjunction with perforated paper, the braking arrangement according to the present invention functions best when the first and second gearwheels 12, 22 are substantially identical. Suitably, each gearwheel should be provided with nine to fifteen substantially identical teeth, preferably twelve teeth. As shown in Figs. 4a and 4b, each tooth 38 should have only rounded edges, i.e. no sharp edges, to thereby prevent the continuous material from being ripped. In a preferred embodiment of the invention in which the braking arrangement 10 is utilized with a dispenser for perforated paper, each gearwheel has an external diameter d of 42 mm and is provided with 12 teeth. The height h of each tooth is 7 mm, the m~X;mllm distance between opposed faces of the tooth w is 4.7 mm, with the various radii of curvature of the tooth a, b, c, as shown in Fig. 4b being 1.4, 10 and 2.35 mm respectively. Finally, the distance x from the tip of each tooth to the region of mA~;mllm width is 4 mm.
CA 022438~3 1998-07-21 The gearwheels 12, 22 may be made from extruded aluminium and the spindles 16, 28 from a suitable steel. The chassis 18 may be made from aluminium or a glassfibre-reinforced polymer.
As mentioned earlier, the braking arrangement 10 according to the present invention may suitably be utilized in a dispenser for dispensing a continuous paper sheet. The paper sheet may be in the form of a roll of paper having a longitudinal axis. Depending on the type of dispenser, the roll of paper may be arranged in the dispenser such that the longitudinal axis o~ the roll of paper is aligned with the nozzle 19 on the chassis 18. In such a case, it is advantageous if the roll is such that paper can be drawn from the centre of the roll rather than the periphery.
Alternatively, the roll of paper may be arranged in the dispenser such that the longitudinal axis of the roll of paper is substantially parallel to the first and second axes 14, 24 of the braking arrangement 10.
Naturally, the invention is not to be restricted to the embodiments descr~bed above and shown in the drawings, but may be varied within the scope of the appended claims. For example, the braking arrangement may be used in dispensers 2~ of material other than paper.
The present invention relates to a braking arrangement for use in connection with dispensers of continuous material such as paper. The invention further relates to a dispenser equipped with such a braking arrangement.
