Description

[Detailed description of the invention] [Industrial field of application] The present invention relates to a paper sheet processing machine that stacks paper sheets such as banknotes, various cards, slips, etc. vertically or horizontally in an aligned state. The paper sheets are arranged and stacked, separated one by one from the group of paper sheets, fed out, counted,
Paper sheet counting machines that perform identification, etc., banknote sorting machines,
The present invention relates to a paper sheet feeding gate device used in paper sheet processing machines such as banknote deposit machines and banknote dispensing machines.

[Prior art of invention and its problems]

As shown in FIG. 6, the gate device used in the conventional paper sheet processing machines of the above type includes feed rollers F, F, which rotate in the normal direction;
Gate rollers G and G form a pair with circumferential surfaces facing F.
are provided in two pairs in the axial direction on the shafts A and B, and a single groove C and C extending over the entire circumference is formed on each peripheral surface of the feed rollers F and F and gate rollers G and G at predetermined positions in the roller width direction. By positioning the outer circumferential surface of one roller so as to face the groove of the other roller, separation and feeding of one paper sheet P is performed using the outer circumferential surface of both opposing rollers and the groove. A closing gate gap is formed.

In the conventional gate device described above, the outer circumferential surfaces of feed rollers F, F are all circumferential surfaces of the same height with radius R ₁ , and the outer circumferential surfaces of gate rollers G, G are all circumferential surfaces of the same height with radius R ₂ . The outer circumferential surfaces of the feed rollers F, F on the side closer to each other when viewed in the axial direction are arranged so as to face the grooves at the innermost ends of the gate rollers G, G when viewed in the axial direction.

However, in the gate device configured as described above, the positions of the gate rollers G, G with respect to the feed rollers F, F are adjusted in order to reliably feed the paper sheets P one by one. The closer the feed rollers F and F are placed, the more the outer peripheral surface of one roller gets into the groove of the other roller, the more the possibility of two sheets passing at the same time can be eliminated. In many cases, the paper sheets are not fed out (the leaves are not fed out), and this causes problems in that the paper sheets are easily damaged and at the same time, the feeding ability is reduced. Moreover, the paper sheets P that are fed out are folded into a wave shape by the grooves of each roller and the outer peripheral surface of the opposite roller, and the corners of the rollers of the paper sheets P that have become wavy are folded. The parts corresponding to parts D and D are easily damaged by the corner parts D and D, so if the gate rollers G and G are separated from the feed rollers F and F, empty feeding and damage to paper sheets can be prevented. Although this can be avoided, two sheets are often fed out at the same time, and the sheet P located between the gate rollers G becomes slack in its width direction, causing the sheets to be fed out by the feed rollers F and gate rollers G, G. This brings about the drawback that the separation ability of Class P cannot be fully demonstrated.

[Purpose of invention]

In view of this, the present invention was developed with the aim of eliminating the drawbacks of the above-mentioned prior art, and it is possible to reliably feed out each sheet one by one while also eliminating damage to the sheets. The present invention provides a paper sheet feeding gate device that can be used.

[Summary of the idea]

In order to achieve the above purpose, in this invention,
Two pairs of a feed roller that rotates in the normal direction and a pair of gate rollers whose circumferential surfaces face the feed roller and form a pair are provided in the axial direction, and the feed roller and the gate roller each have a feed roller and a gate roller provided on their respective circumferential surfaces at predetermined positions in the roller width direction over the entire circumference. At least one groove is formed, and by positioning the circumferential surface of one roller opposite to the groove of the other roller, it is possible to separate one sheet of paper between the circumferential surface of both opposing rollers and the groove. A relationship in which each groove portion at the innermost end in the axial direction of each feed roller is located opposite each peripheral surface located at the innermost end in the axial direction of each gate roller. Two pairs of feed rollers and gate rollers are arranged on the shaft, and each feed roller is arranged on the shaft, and the innermost circumferential surface of each feed roller in the axial direction has a larger diameter than the other circumferential surfaces of the feed roller. At the same time, an inclined surface is formed on the groove side wall on the large diameter circumferential surface side of the groove adjacent to each large diameter circumferential surface of each feed roller, and the slope is inclined in the direction in which the groove width widens. Among multiple sheets of paper that are simultaneously entering the gap, each large-diameter peripheral surface rotates in contact with the paper on the feed roller side while applying tension outward in the feeding width direction, and the contact rotation causes the paper to The paper sheet is fed out from the gate gap with the tensile parts of the types in pressure contact with each large-diameter circumferential surface, and the paper sheet is reliably placed in the gate gap.
This is characterized in that the sheets are separated.

As a result, when this state is reached, only the lower few banknotes P are supported by the circumference of the hard roller 13 and the feed roller 7, and the upper banknotes P are supported by the free rotation roller 11 and the feed roller 7. It will be done. Therefore, most of the weight of the stored banknotes P is on the free rotating roller 1.
1 and the feed roller 7, and no weight is applied to the hard roller 13.

In this way, when the kicking portion 13A of the kicking roller 13 comes into contact with the lower surface of the lowest bill P, only one bill is fed out due to the frictional force, and is sent out through the feeding gate device composed of the feed roller 7 and the gate member 10. , and are sent out of the cassette 1 by the carriers 1A, 1A.

In the above-mentioned feeding gate device 50, among the plurality of banknotes P that are trying to enter the gate gap at the same time, the large diameter circumferential surfaces 7B, 7B of the feed rollers 7, 7 feed out the banknotes P on the side of the feed rollers 7, 7 in the feeding width direction. The banknote P is rotated in contact while applying tension to the banknote P, and due to the contact rotation, the tensioned portion of the banknote P is brought into pressure contact with each of the large-diameter circumferential surfaces 7B, 7B, and is fed out from the gate gap. Separation of one bill P is reliably performed. Further, at this time, the banknotes P are prevented from being damaged by the inclined surfaces 7D, 7D on the inside of the large-diameter circumferential surface.

The banknotes P sent out from the cassette 1 are
It is discharged from the dispensing port 22 via the inner conveyance path 37 and dispensing conveyance paths 35 and 36.

In the illustrated embodiment, the present invention is applied to a cassette for a circulation processing machine for banknotes, but it is also possible to apply the present invention to a feeding device such as a storage box used as a single unit, or to feed stacked paper sheets one by one from the bottom. Of course, it can also be used as a feeding device. Further, in the above embodiment, the gate roller 10 is explained as being freely rotated only in the reverse direction by a one-way clutch, but it may be a fixed roller or a fixed gate member. It is also possible to intermittent reverse rotation in conjunction with the feed roller 7 only when feeding paper sheets.

[Effects of the invention] As explained above, the feeding gate device of the present invention is provided with two pairs of gate rollers in the axial direction, a feed roller that rotates normally, and a pair of gate rollers whose circumferential surfaces face the feed roller. At least one groove is formed on each circumferential surface of the roller at a predetermined position in the roller width direction over the entire circumference, and the circumferential surface of one roller is positioned opposite to the groove of the other roller, so that the grooves of the other roller are opposed to each other. In a device in which the circumferential surfaces of both rollers and the groove portion form a gate gap for separating and feeding paper sheets, a gate gap located at the innermost end in the axial direction of each of the gate rollers is provided. Two pairs of feed rollers and gate rollers are arranged on the shaft in such a relationship that the grooves at the axially innermost end of each feed roller are located, and the circumferential surface of the axially innermost end of each feed roller is located close to the other circumferential surface of the feed roller. In addition to forming a large-diameter circumferential surface with a diameter larger than the surface, the groove side wall on the large-diameter circumferential surface side of the groove adjacent to each large-diameter circumferential surface of each feed roller has an inclined surface that slopes in the direction in which the groove width widens. As a result, each large-diameter circumferential surface rotates in contact with the paper sheets on the feed roller side among the multiple paper sheets that are simultaneously entering the gate gap while applying tension outward in the feeding width direction. Due to the contact rotation, the paper sheet is fed out from the gate gap with the tension part of the paper sheet being pressed against each large-diameter peripheral surface, thereby ensuring that each sheet of paper sheet is separated in the gate gap. Moreover, since there is an inclined surface on the inside of the large-diameter peripheral surface of the feed roller, there are various effects such as avoiding damage to the paper sheets when tension is applied to the paper sheets.
