Description

  The present invention is, for example, a paper sheet stacking and feeding device that stacks banknotes from a transport path to a stacking unit by deposit processing in an automatic teller machine (ATM) and feeds banknotes from a stacking unit to a transport path by withdrawal processing. In particular, the present invention relates to a paper sheet handling apparatus suitable for accumulating and storing a plurality of types of paper sheets having different width sizes in the transport direction.

  2. Description of the Related Art Conventionally, as a paper sheet processing apparatus that processes only a single paper sheet of a width size, for example, there is an apparatus configured as shown in FIG. That is, a bottomed box-shaped stacking portion 92 having an internal space 91 is provided, and an inlet portion 93 is formed on the upper side of the stacking portion 92 so as to communicate with the internal space 91, and immediately before the inlet portion 93. The stacking roller 94 and the impeller 95 are arranged up and down to constitute a stacking function, and the opposing rollers 96 and 97 are arranged up and down in the front portion of the elements 94 and 95 on the upstream side of conveyance. It is set.

Here, the impeller 95 includes a roller 95a and a plurality of blades 95b extending radially outward from the outer peripheral portion of the roller 95a. According to this conventional paper sheet processing apparatus, the depth dimension Lb of the internal space 91 of the stacking unit 92 is set to a value obtained by adding the predetermined dimension n to the length La of the paper sheet 98 in the transport direction, that is, Lb = La + n. ing. The front end of the paper sheet 98 that has entered the internal space 91 from between the stacking roller 94 and the impeller 95 through the inlet portion 93 once collides with the vertical wall 92 a of the stacking section 92, and the rear of the paper sheet 98. The end is knocked down by the blades 95b of the impeller 95, and the paper sheets 98 are dropped in the stacking direction, and a rush space for the subsequent paper sheets is secured to enable continuous stacking.
Here, the paper sheets deposited inside the stacking unit 92 are aligned in the range of the depth dimension Lb. Therefore, the paper sheets can be fed out from the entrance portion 93 to the transport path without skewing.

Conventionally, regarding a paper sheet stacking apparatus that handles a plurality of paper sheets having different width sizes, for example, one disclosed in Japanese Patent Application Laid-Open No. 2001-312010 (Patent Document 1) is known. This stacking apparatus is provided with a means for urging the sheets toward the stacking side in order to accumulate and store various types of sheets having different width sizes.

JP 2001-31010 A JP 2004-107079 A JP 2005-247497 A

  In the conventional apparatus as described above, for example, in a paper sheet stacking and feeding apparatus that processes only a single width-sized paper sheet, the paper sheet corresponds to the depth dimension Lb of the stacking unit internal space 91 in FIG. When the length La of the class 98 is too small, it becomes impossible to knock down the rear end of the paper sheet 98 with the blade 95b of the impeller 95, and the paper sheet and the subsequent paper sheet collide with each other. There is a problem. If a paper sheet 98 having an excessively small length La and an optimum paper sheet are simultaneously stacked in the stacking unit, this problem is remarkably generated in the paper sheet having an excessively short length La.

  In addition, when paper sheets of different sizes are accumulated at the same time and then fed out from the carry-in entrance, paper sheets with an excessively small length La are not regulated in the internal space of the accumulation section and are deposited in a free orientation. , Edges of paper sheets are not aligned. When the paper sheets are fed out and conveyed from the stacking unit to the conveyance path, the paper sheets are skewed, empty, two sheets are taken out, taken out, and chained. Paper sheets in such a state may cause paper jams in the middle of the conveyance path.

  The prior arts disclosed in Patent Document 1 and Patent Document 2 described above require the accompanying device for solving the problem of the single-size paper sheet stacking and feeding device, and there is a problem that the structure becomes complicated.

  An object of the present invention is to provide a paper sheet stacking and feeding device capable of stacking paper sheets of different sizes in an aligned manner and preventing abnormal transport of the paper sheets when the paper sheets are fed. is there.

The present invention preferably includes a stacking mechanism for dropping and stacking a plurality of paper sheets having different lengths in the transport direction, which are transported through the transport section, and the paper sheets stacked in the stacking section. In the paper sheet stacking and feeding device having a feeding mechanism for feeding the paper to the transport unit, the stacking mechanism is provided between the transport unit and the stacking unit, and is configured by a member having a higher friction coefficient than the friction coefficient of the paper sheet. A rotating member having a plurality of pieces, and when the paper sheets are stacked, the paper sheets are beaten with the pieces of the rotating members and moved to the front side in the conveying direction while dropping the paper sheets. It is configured as a paper sheet stacking and feeding device that stacks the end surfaces of the paper in an aligned manner.
In a preferred example, the length of the piece of the rotating member is set at the rear end of the paper sheet even when the leading edge of the paper sheet discharged to the stacking part is at a position where it reaches the wall surface of the stacking part facing the inlet / outlet. It is configured to be touchable length.
Preferably, the rotating member has a plurality of pieces including a first piece and a second piece, and during the period (period) until the paper sheets discharged to the stacking unit fall and accumulate. The paper sheets are arranged concentrically around the rotation axis so that the paper sheets are beaten once or more with one piece and the paper sheets already deposited with the second piece are beaten once or more in a period.
Preferably, the stacking unit is provided with a lifting platform on which the sheets can be stacked and moved up and down, and when the sheets are stacked, the lifting member can be brought into contact with the rotating member piece. It is configured to move to the correct position.
Further, in a preferred example, a feed roller for conveying paper sheets is disposed between the conveyance path and the stacking unit, and the rotating member is arranged so as to be in contact with the outer periphery of the feed roller; It has a link part that rotates the rotating member around a predetermined axis. When paper sheets are stacked, the link part is rotated to bring the cylindrical part into contact with the feed roller, and when the paper sheet is fed out, the cylindrical part. Is configured to drive the link member so as to keep the rotating member at a predetermined position apart from the feed roller.

  According to the present invention, paper sheets of different sizes can be aligned and stacked. Therefore, abnormal conveyance such as skew can be prevented when the paper sheet is fed out.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
First, the structure of each part of the paper sheet stacking and feeding apparatus 1 shown in FIGS. 1, 2, 3 and 4 will be described. FIG. 1 is a configuration diagram viewed from above the paper sheet stacking and feeding device 1, FIG. 2 is a configuration diagram viewed from the side during the feeding operation of the paper sheet stacking and feeding device 1, and FIG. 3 is a paper sheet stacking and feeding device. FIG. 4 is a front view of the paper sheet stacking and feeding apparatus 1 including a feed shaft 15, a gate shaft 16, and a shaft 23, which will be described later.

  In these drawings, the paper sheet stacking and feeding device 1 has a stacking space 11 having a depth dimension Lb in the transport direction. Lb is a value obtained by adding a predetermined dimension n to the maximum value of the paper sheet conveyance direction dimension (width in the short direction of the paper sheet) La of a plurality of sizes to be processed. The accumulation space 11 is formed in a box shape by a guide 13 having a paper sheet inlet / outlet 10, a wall surface 12 e facing the guide 13, and wall surface guides 12 b and 12 c for regulating a space in the longitudinal direction of the paper sheet. A lifting plate 30 is provided at the bottom of the accumulation space 11. The sheets A are stacked horizontally on the lifting plate 30. The elevating plate 30 is driven by a forward / reverse motor (not shown) such as a stepping motor along the shaft 34 to move up and down via the belt 31.

On the upper part of the paper sheet stacking and feeding apparatus 1, a feed shaft 15 is installed in a horizontal direction to be supported, and two substantially cylindrical feed rollers 17 are mounted on the feed shaft 15 at a predetermined interval. The feed shaft 15 is equipped with a gear (not shown), and the rotational force of a forward / reverse motor (not shown) is obtained as a driving force through the gear. The forward / reverse motor is controlled by normally known control means (not shown) to perform forward / reverse rotation.
Behind the feed roller 17, a pickup roller 61 and a pulley 63, each having a belt 62, are provided. The pickup roller 61 swings up and down by driving a forward / reverse motor by a control means around the pulley 63 on the back side during the accumulation operation and the feeding operation. The pickup roller 61 obtains a rotational force of a forward / reverse motor (not shown) as a driving force via a pulley 63 and a belt 62. Below the feed roller 17, two gate shafts 16 are installed in the horizontal direction and are supported by bearings. A substantially cylindrical gate roller 18 is mounted on the gate shaft 16.

  A shaft 23 is installed horizontally in the conveyance guide 13. Two link portions 22 are attached to the shaft 23. A shaft 21 is installed at the tip of the link portion 22 to be a bearing, and the rotating member 20 is mounted. The rotating member 20 swings up and down by a forward / reverse motor about the shaft 23 during the accumulation operation and the feeding operation via the link portion 22.

  The rotating member 22 is composed of a rotating piece 20b, a base portion 20a, and a cylindrical portion 20c at six equal positions, and has a friction coefficient higher than the surface friction coefficient of the paper sheet to be processed, preferably integrally molded with a rubber material. Configured. The length of the rotating piece 20b is set to such a length that the distance Lc from the tip of the rotating piece 20b to the wall surface 12e is smaller than the minimum value of the length La of the plurality of sizes of paper sheets to be processed during the stacking operation.

In the apparatus having the above configuration, the following operation is performed at the time of integration and feeding.
First, the operation during integration will be described.
As shown in FIG. 3, the pickup roller 61 is moved above the stacking space 11 during stacking so that it does not come into contact with paper sheets entering the stacking space 11.
The rotating member 20 moves upward via the link part 22, and the cylindrical part 20 a is in a position where it contacts the circumference of the feed roller 17. As a result, the rotating member 20 rotates with the driving force applied from the feed roller 17.

  The paper sheets 3 carried in from the entrance / exit 10 are discharged into the accumulation space 11 by the conveying force of the feed roller 17. The discharged paper sheets 3 collide with the wall surface 12e and then accumulate on the elevating plate 11. While the paper sheet 3 is deposited on the lifting plate, the trailing edge is hit by the rotating piece 20b. When the rotating piece 20b and the paper sheet 3 come into contact with each other, as shown in FIG. 5, the rear end of the paper sheet 3 is drawn toward the guide 13 along the rotation of the rotating piece 20b due to the friction generated between them. It is done.

In this way, by pulling the rear end of the released paper sheets toward the guide 13 and making the rear end face coincide with the guide 13, the end faces of the paper sheets can be stacked while being aligned. Furthermore, since the paper sheet 4 on which the paper sheets are accumulated on the lifting plate 30 is rotated until the paper sheet 3 falls, the rotating piece 20b hits the paper sheet 4 as shown in FIG. Thus, it is possible to prevent the end face (the end face on the guide 13 side) of the paper sheet 4 from being shifted after being deposited.
The elevator 30 is moved to a position where the sheet 4 accumulated on the surface and the piece 20b come into contact with each other by appropriate control according to the accumulated height of the accumulated sheets. As described above, even when sheets of different sizes in the transport direction are sequentially stacked in one stacking space 11, the end surfaces of the sheets can be aligned with the guide 13.
Note that the driving force for rotating the rotating member 20 may be a separate driving means instead of the feed roller 17. In the case where a separate driving means is used, the cylindrical portion 20c may not be configured.

Next, a paper sheet feeding operation will be described.
As shown in FIG. 2, at the time of feeding, the rotating member 20 moves downward by driving the link mechanism 22, and the rotating piece 20 b is retracted to the inside of the conveyance guide 13 (outside the accumulation space 11). Thus, since the rotating member 20 moves to the inside of the conveyance guide 13 and retracts, when the paper sheet is conveyed to the entrance / exit 10, the paper sheet collides with the rotating piece 20b and becomes an obstacle to conveyance. I can prevent it.

The pickup roller 61 for feeding out the paper sheet moves downward, and the lift plate 30 is driven to move upward. At this time, the front end surface of the paper sheet 2 immediately before the pickup accumulated on the lifting platform 30 is aligned and aligned with the guide 13 regardless of the width size of the paper sheet.
When the pickup roller 61 is driven to rotate in this state, the stacked sheets 2 are picked up one by one by the pickup roller 61 and sent out to the inlet / outlet 10.

With the configuration and operation as described above, the transported paper sheet is knocked down by the piece of the rotating member, and pulled toward the guide 13 side by the friction generated between the surface of the rotating member and the paper sheet. Thus, a plurality of paper sheets having different width sizes can be aligned and stacked in the same stacking portion. Further, when the paper sheets are fed out, the paper sheets accumulated with the leading end aligned with the guide 13 can be fed out stably without causing abnormal feeding such as skew emptying, two-sheet feeding, chaining, and taking-out. it can.
In addition, since a conventional incidental mechanism is not required, the number of parts of the paper sheet stacking and feeding apparatus can be reduced, design and manufacturing time can be shortened, and cost can be reduced.

In addition, a present Example is not limited to the said Example, It can implement variously.
For example, the number of the rotating pieces 20b is not limited to six, and may be one or more. Moreover, in the said Example, although two rotation members 20 are installed in the longitudinal direction of paper sheets, the structure which installs not only this but one or one may be sufficient.
In the above-described embodiment, the rotating member 20 is moved to retract the rotating piece 20b during feeding, but the rotating member 20 is not moved, but the cover member (not shown) is moved to curve the rotating piece 20b. You may make it hide inside the conveyance guide 13. Further, the paper sheets are not limited to banknotes, and can be applied to accumulation and feeding of cards, paper, and printed paper.
