A device equipped with a mechanism for transporting and depositing securities such as securities.
Furthermore, in a printing apparatus or the like having a mechanism for transporting and accumulating recording paper, creases, wrinkles, and curl habits formed in advance on these paper sheets or formed in the course of transportation, This is a cause of defective deposition when depositing paper sheets. For example, in a money handling device, there is one that has a function of receiving bills inserted from the outside, conveying them to the inside, and holding them in a temporary holding unit up to a certain number, and the temporarily held bills are stored in the device. Processing such as transportation to a safe for storage or transportation to a payout port for refund is performed. In FIG. 2A, upper and lower two rollers 2 and 3 are arranged at the receiving side position of the banknote stacking unit (temporary storage unit) 1, and the banknote P is discharged from the nip portion of both rollers 2 and 3 into the stacking unit 1. It is a thing.
When a designated number of banknotes are accumulated in the stacking unit 1, the stopper 7
At the same time as in (b), the rear end of the table 5 rises and the banknote bundle is collectively transferred to the downstream side.

The lower roller 3 is integrally provided with blades 3a extending radially in the radial direction, and the blades 3a properly drop the banknote P into the stacking unit 1. Further, even if the ejected bill has a crease or the like, the blade 3a presses the rear end of the ejected bill so that the succeeding bill is not affected by the crease or the like of the preceding bill. It is considered to be discharged to. However, even if such a blade 3a is provided, in the case of a banknote or the like having a large folding tendency as shown in (c), the succeeding banknote is not fully pressed by the blade 3a and the succeeding banknote becomes a rising part of the preceding banknote. Collision causes defective deposition. Since the accumulation failure causes a conveyance failure such as a jam in the subsequent bill bundle conveyance processing, improvement is desired.

Further, in the apparatus shown in FIG. 2, the banknote stacking unit 1
The other end of the table 5 is vertically movable around the fulcrum A, and the idler roller 6 is rotatably supported on the other end of the table 5. Further, a stopper 7 is arranged on the horizontal extension of the nip portion between the upper and lower rollers 2 and 3 and rotates in the vertical direction about a fulcrum B.
This stopper 7 is interlocked with the rotating operation of the table by a connecting means (not shown), and when the table 5 is in the lower position (a), the stopper 7 is in the shielding position as shown in the drawing and passes through the nip portion. It prevents the incoming banknotes from going over the banknote stacking unit 1 and jumping to the downstream side. Further, when the table 5 is in the raised position shown in (b), the stopper 7
As shown in (b), opens the transportation path for the banknote bundle and allows the banknote bundle on the table to move to the downstream side. Further, reference numeral 8 is a paper feed roller fixed at the position shown in the figure, and in (b), the paper feed roller is held while holding the banknote bundle between the paper feed roller 8 and the idle roller 6 under pressure. It is conveyed to the downstream side by the driving force of 8. However, in this conventional device, an interlocking mechanism for interlocking the operation of the table 5 and the stopper 7 and an assembly adjustment work for driving the drive roller 8 at a proper timing without a problem are required. There is a problem that Further, since the interlocking mechanism is provided and the number of parts is increased, the cost is increased and the failure rate is increased.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to embodiments shown in the drawings. 1 (a), 1 (b) and 1 (c) are schematic diagrams showing the structure and operation of a stacking apparatus according to an embodiment of the present invention, where (a) is for stacking, (b) is for discharging a banknote bundle, c) shows a state in which banknotes having a peculiarity are accumulated. The depositing device 10 includes a money handling device having a mechanism for carrying and depositing banknotes such as a vending machine, a money depositing and dispensing device, and a money changer, and a device having a mechanism for carrying and depositing notes such as securities. In addition, in a printing apparatus or the like having a mechanism for transporting and accumulating recording paper, banknotes having a crease, a wrinkle, and a curl tendency are accumulated in the accumulating unit 11
It is characterized in that even when it is discharged to the banknote, it is securely pressed to prevent floating and to prevent the collision with the succeeding banknote to improve the stacking property. This deposition equipment
Deposition part 11 having fixed back fence 11a
In the stacking portion 11, a table 13 is pivotally supported so that its tip portion can move up and down around a fulcrum 12 on the upstream side, and an idle roller 14 that is rotatably supported at a proper position in the tip portion of the table.
And a paper feed roller 15 disposed immovably above the idling roller 14 with a predetermined space therebetween, and supported rotatably in the vertical direction about a fulcrum 16 at an appropriate position on the upstream side of the paper feed roller 15. The stopper / holding guide (stopper plate) 17 descending on the table 13 due to its own weight, and the deposition unit 1
It has an upper discharge roller 18 and a lower discharge roller 19 located at the upstream end of No. 1. The lower discharge roller 19 is provided with a blade 19a for pressing bills.

Stopper / holding guide (stopper plate) 17
Is configured so that it can move up and down without interfering with the back fence 11a, the paper feed roller 15, and the lower discharge roller 19. In addition, the locking portion 11 provided on the back fence 11a
By descending on b by its own weight, the table 13
Guide the banknotes ejected above into a proper stacking state. Therefore, the locking portion 11b is arranged so that the lower surface of the guide 17 does not come into contact with the uppermost banknote that has completed stacking.
The position is designed. That is, in the state in which the maximum number of accumulated sheets (maximum reserved number of sheets) is accumulated, the uppermost banknote is placed in the guide 17
Is dimensioned so that it does not touch the underside of the.
That is, the guide 17 in the lowered position has only the function of guiding the discharged bills.

At the time of stacking shown in FIG. 1 (a), the stopper / holding guide 17 is hung by its own weight to a predetermined lowering position by a locking portion 11b provided on the back fence 11a, and is fed to the back fence 11a. Paper roller 1
The conveyance path between the sheet and the sheet 5 is closed. In this state, when the banknotes P are fed into the space between the table 13 and the stopper / holding guide 17 one by one from the nip portions of the vertical discharge rollers 18 and 19, the banknotes come into contact with the stopper / holding guide 17. It is properly loaded on the table while being guided. Note that the bottommost bill P on the table 13 is actually positioned on the idle roller 14.

When a predetermined number of banknotes P are stacked on the table 13 and the banknote bundle is collectively sent out from the delivery path above the back fence 11a to the downstream side, a driving means (not shown) is operated to make a fulcrum. The table 13 is raised around 12 as shown in (b). Then, the idle roller 1
The banknote bundle is clamped and held between the sheet feeding roller 15 and the paper feed roller 15, and is lifted to the upper right, and the right end portion of the banknote bundle is directed to the delivery path above the back fence 11a. At this time, since the stopper / holding guide 17 is pushed up by the table 13 via the banknote bundle, the stopper / holding guide 17 can be rotated upward about the fulcrum 16 to open the transport path. When the paper feed roller 15 is rotated in the paper feed direction in this state, the bundle of banknotes is collectively sent out to the downstream side through the conveyance path in cooperation with the idling roller 14. For example, the discharge roller pair 20 may be arranged on the downstream side. (c) shows a case where a banknote having a crease is discharged onto the table 13, and in this case, the inclined lower surface of the stopper / holding guide 17 at the lowered position presses the banknote having a crease. While
Since the table 13 is guided to the inner part of the table 13, the position of a banknote having a tendency to fold is also regulated (the lifting is suppressed) within the range reached by the rubber blades 19a, and the blades 19a are surely pressed to the next banknote. It is possible to prevent the stacking state from being deteriorated by colliding with the preceding bill. The present invention can also be applied to a deposition apparatus that does not have the blade 19a. As described above, in the present invention, the stopper / holding guide 17 itself is not provided with a drive source for lifting and lowering, and is merely configured to be movable up and down. It is only pushed up or down in conjunction with the lifting operation of 13.
Therefore, a mechanism for interlocking the table 13 and the stopper / holding guide 17 is not required, the configuration is simple, and an adjusting mechanism is not required, so that the cost can be reduced.

[0012]

As described above, according to the invention of claim 1,
When the table is turned up and down without pushing the stopper plate that opens and closes the conveyance path that conveys the stack of paper sheets accumulated on the table to the downstream side, the table pushing force and pressing force Since it is moved up and down by the operation, it is possible to perform the batch conveyance operation of the banknote bundle similar to the stacking device of the conventional example without providing a special interlocking mechanism. Therefore, the configuration, control, and adjustment are facilitated, and the cost can be reduced. Further, even when the discharge roller is provided with a blade that presses the trailing end of the paper sheet, the paper sheet having a crease is regulated by the lower surface of the stopper plate that is lowered by its own weight to prevent the sheet from floating. Therefore, the blade is surely pressed, and it is possible to prevent the deposition failure in the deposition portion which is caused by the formation of the creases, wrinkles, curls, and the like.
