BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a banknote handling apparatus such as an automatic vending machine, a money changer, and the like, which has a safe for receiving banknotes and a mechanism for temporarily stacking and storing the banknotes received in the safe and then dispensing them as change. , For improving the adjusting mechanism of the pressing force of the pusher for dropping the banknotes received in the safe to the stacking table for stacking and supplying the pressure for feeding, in detail, for taking out from the bottommost banknote on the stacking table. The present invention relates to a recycle-type safe in which it is possible to prevent the occurrence of a situation such as double feeding, inability to feed paper, etc. by always making the paper feeding pressure to the feeding roller appropriate.

[0002]

2. Description of the Related Art An automatic vending machine, a currency exchange machine, etc. are used to identify and determine the authenticity of inserted bills, denominations, etc. In some cases, the banknotes are temporarily stored in a safe and also equipped with a return mechanism for taking out the stored banknotes one by one and using them for change or withdrawal. FIG. 4 is a diagram showing a storage structure in a conventional return-type cash box, and the cash box 1 is arranged in a bill handling apparatus 2. Safe 1
A bill insertion slot 6a and a bill ejection slot 6b are provided on the outer wall of the case 5.
The banknote stacking plate 7 is vertically movable in the case 5 and is biased upward by the spring 8. The stacking plate 7 is provided with a feeding roller 9 and is rotated in the direction of the arrow to feed the lowermost banknote to the outlet 6b. The take-out port 6b is provided with a take-out roller pair 10 to convey the taken-out bills to a pay-out section (not shown).

Reference numeral 11 is a pusher, which can be moved up and down from a raised position shown by a dotted line to a lowered position shown by a solid line by a drive mechanism (not shown). While the banknotes are being taken out from the taking-out port 6b, the stacking plate 7 is in the lowered position shown by the solid line, and at this time, the pusher 11 applies a constant feeding pressure to the feeding roller 9 to realize proper feeding. A predetermined pressing force is applied by dropping onto the banknote P on the stacking plate.
The lowering of the stacking plate 7 is performed by the pressing force from the pusher 11, and when the stacking plate 7 reaches the sheet feeding position shown by the solid line, the locking hook 15 pivotally supported at the lower part of the stacking table 7 is moved to the safe side. It is engaged with a pin 16 provided to prohibit the descending of the stacking plate 7. The hook 15 is unlocked by unlocking means (not shown). As this unlocking means, for example,
A means for rotating the hook 15 in the releasing direction, a means for retracting the pin 16 or the like are used.

Insertion roller pair 1 provided near the insertion opening 6a
When new banknotes are sent into the safe by 2,
When the pusher 11 retreats to the dotted line position, the stacking plate 7 is released from the pressing force of the pusher 11 and rises to the dotted line position, and a new banknote is stacked on the banknote P on the stacking table 7 and then the pusher 11 is newly installed. Drop it onto a banknote and hold it down. Actually, guide means and the like are provided for accurately placing new banknotes on the stacking table, but they are omitted here. When the banknotes accumulated in the safe having the above-mentioned configuration are taken out of the safe for change and withdrawal, the pusher 11 is placed on the upper surface of the banknotes on the stacking table while the stacking table 7 is lowered to the solid line position. And press down (feed pressure)
The feeding roller 9 is rotationally driven in the paper feeding direction while adding the above.

However, when the stacking table 7 is pushed down by the pusher 11, the banknotes sandwiched between the two are strongly pressed. Therefore, when the stacking table 7 is forbidden to descend, the feeding motor is out of synchronization. In addition, due to the high pressure between bills, double feeding often occurred. In order to solve such a problem, it is necessary to prevent double feeding by slightly raising the pusher to reduce the pressure after the lowering of the stacking table is prohibited (the feeding position shown by the solid line). However, it is necessary to finely adjust the pusher return amount according to the different flatness due to the presence or absence of peculiarities such as old and new bills, wrinkles, bending, etc., and the required pressure force. Therefore, it is impossible for the conventional mechanism for returning the pusher by a certain distance to flexibly deal with various different bill states and to secure a stable paper feeding capability. In addition, a clutch is interposed between the pusher and the pusher driving motor, and when the stacking table 7 is lowered to the sheet feeding position and locked, the clutch is turned off to apply a pressing force only by the weight of the pusher. However, there is a problem that the configuration is complicated and the cost is increased.

BEST MODE FOR CARRYING OUT THE INVENTION The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings. 1 (a), (b) and (c) are schematic diagrams showing the principle of the present invention, and FIG. 4 is referred to for the constitution of the safe other than the constitution shown. This safe 20
Is stored in a bill handling device such as an automatic vending machine or a money changer, and a stacking table 21 on which bills are placed is constantly urged upward by a spring 22 in a housing (not shown). The stacking table 21 stacks the banknotes received from the insertion slot 23 shown in FIG. The deposition table 21 has a feeding roller 24,
Is at the lowest position, the feeding roller 24 rotates to take out the lowermost bill and send it out from the bill take-out opening 25. Reference numeral 15 is a hook provided on the deposition table 21, and 16 is a locking pin provided on the safe housing.

A pusher 30 located above the deposition table 21.
Are supported by a drive mechanism 31 so as to be able to move up and down.
The drive mechanism 31 includes a pulse motor 32, an operating piece 33 that is connected to an output shaft of the pulse motor 32 to rotate, and a guide 34 provided on the pusher 30. The guide 34 includes the operating piece 33. Although there is a receiving portion 34a for receiving the tip portion, this receiving portion 34a has a play for freeing the tip portion of the operating piece 33 within a predetermined range.

Reference numeral 35 is a bill holding member, and as shown in (a), the pusher 30 is in the raised position and a new bill P1 is provided.
When the bills are being fed from the insertion slot 23, the bills are lowered onto the banknotes on the stacking table 21 to hold them, while the pusher 30
Replaces the pusher and rises when the banknote descends to transfer new banknotes onto the stacking table ((b)).

FIG. 1A shows a state in which the pusher 30 is in the raised position and a new bill P1 has been fed from the paper feed port 23. At this time, the motor 32 operates the operating piece 33 as shown in the figure. Since it is operated to the raised position, the pusher 30
Can take an elevated position. Next, in (b), the motor 3
The pusher 30 can lower the banknote co-depositing table 21 to the position shown in the figure because the operation piece 33 operates the actuating piece 33 to the position shown in the figure.

The characteristic construction of the present invention is that the guide 34 is pushed after the pusher is pushed down to a predetermined position as shown in FIG. 1 (b).
This is because the tip of the operating piece is slightly raised within the play of the receiving portion 34a to slightly weaken the pressure applied to the bill. That is, in the present invention, since the pusher and the drive motor are not directly connected but are connected via the operating piece and the guide having the play, it is possible that the deposition table is locked by the hook 15 and the pin 16 by the lock detection sensor (not shown). After being detected, the pusher is brought into a free state by returning the motor by a certain amount so that a certain force is applied to the bill.

2 (a) (b) (c) and FIGS. 3 (a) (b) (c) are main parts of an embodiment of a deposition apparatus embodying the principle of the present invention shown in FIG. It is a figure and Drawing 2 (a) and Drawing 3 (a) (b) and (c) are figures showing a continuous operation. This deposition apparatus includes an elevating guide 41 which is erected vertically on a base 40, and an elevating member 42 which is supported by the elevating guide 41 so as to be vertically movable.
The pusher 30 integrated with the lifting member 42, the deposition table 21, the spring 22, and the drive mechanism 31 for driving the pusher 30 up and down. The drive mechanism 31 has one end fixed to the pulse motor 32, the gear 43 meshing with the output gear 32a of the pulse motor 32, the shaft 43a of the gear 43 (or another position on the gear), and the other end having an outer diameter. It has an operating piece 33 which is projected in the direction and whose tip is located in a space 30a (corresponding to the receiving portion 34a) in the pusher 30. A roller 44 is rotatably supported at the other end of the operating piece 33 so as to reduce resistance when the tip of the operating piece moves in the space 30a.

A slit 45 is formed at the bottom of the pusher and extends in the left-right direction in the drawing (the moving direction of the tip of the operating piece). The operating piece 33 is inserted into the inside of the pusher through the slit 45, and the roller 44 is slit. By making the structure larger than the width, the operating piece is prevented from falling off the slit 45. This void 30a is shown in FIG.
It corresponds to the receiving portion 34a in the principle diagram shown in FIG. 3, and the top and bottom width of the void 30a is a play. The roller 44 can be freed in the vertical direction within the space 30a. The roller 44 is rotatably supported at the tip of the actuating piece 33 (or fixed so as not to rotate) so as to be freely rotatable, and the material thereof is rubber, resin or the like.

In the illustrated embodiment, the drive mechanism such as the motor 32 and the gear 43 is arranged at the lower position of the pusher 30, but the same function can be obtained even if the drive mechanism is arranged at the upper position of the pusher. Can be realized.

In the above structure, FIG. 3 (a) shows the pusher 30 in the raised position for receiving a new bill, and FIG. 3 (b) shows that the bill P on the stacking table 21 is spring-loaded. The stacking table 21 is lowered to the feeding position by pushing it down against 22, and the stacking table 21 is locked at the feeding position by the hook 15 being locked by the locking pin 16. At the time of (b), the roller 44 at the tip of the operating piece 33 is in contact with the bottom surface of the space 30a and pushes it down, but at the time when the actual feeding is started, the state of (b) is maintained. Instead, as shown in (c), the pulse motor 32 is rotated in the reverse direction so that the roller 44 is slightly returned upward within the play range of the void 30a. As a result, the roller 44 is separated slightly upward from the bottom surface of the void, the pressure applied to the banknote P is reduced, and it is possible to realize appropriate feeding without double feeding.

In the state of FIG. 3 (c), when a control signal to the effect that the banknotes should be delivered is output to the delivery roller driving motor, the delivery roller 24 rotates at a predetermined timing and the banknotes are delivered. It is discharged at a predetermined timing. At this time, the pushing down force from the operating piece 33 is reduced within the play range of the void 30a, while the pressing force due to the own weight of the pusher 30 is still applied to the bill, so that the idling roller 24 does not rotate. In addition, it is possible to sufficiently prevent double feeding. That is, in the state of FIG. 3C, not only the weight of the pusher 30 but also the pressing force from the operating piece 33 still acts on the bill, so that the weight of the pusher itself and the return distance of the operating piece are appropriately set. As a result, it becomes possible to secure a good paper feeding capability.

The operation of moving the operating piece 33 up and down is as follows.
Since it is all performed by the pulse motor 32, it is possible to move up and down by a minute distance unit, and by adjusting the ascending distance of the roller 44 according to the occurrence of double feeding or idle rotation, an appropriate pressure by fine adjustment of the sheet feeding pressure is achieved. Can be secured. In the present invention, since the guide of the operating piece is a vacant space provided in the pusher, it is not necessary to secure a special installation space.
It is possible to realize the principle shown in (1), and to achieve compactness and cost reduction. It should be noted that the illustrated embodiment is merely an example, and therefore the configurations based on the principle shown in FIG. 1 all belong to the scope of the present invention.

[0020]

As described above, according to the present invention, when the banknotes deposited on the stacking plate are taken out from the lowermost part and used as change or the like, when the banknotes are fed by the feeding roller on the stacking plate. In addition, the pressing force of the pusher that presses the upper surface of the banknote is obtained from the operating piece that is driven by the pulse motor, and the pusher-side guide (vacant space) that engages with the operating piece is provided with vertical play (accumulation direction). Since the pusher was lowered onto the bill by the actuating piece and the stacking table was locked at the feeding position, the actuating piece was slightly returned upward within the play range, so the pressure from the pusher was reduced, The balance between the weight of the pusher and the pressure applied from the operating piece makes it possible to secure an appropriate pressure on the banknotes and prevent double feeding and idling.
