2. Description of the Related Art In the so-called distribution industry such as supermarkets and convenience stores, POS (point-in-
2. Description of the Related Art There is known a small-sized money processing apparatus that is used by being connected to a register or the like and that performs processing for depositing and dispensing bills and coins.

FIG. 8 is a diagram showing a schematic configuration of the entire money processing apparatus. As shown in FIG. 8, the money processing apparatus 1
The POS register 2 is used in connection with the S register 2. The POS register 2 has the same installation area as the POS register 2, and can be used repeatedly. The money handling apparatus 1 includes a bill processing unit 6 having a bill insertion slot 3, a bill dispensing port 4 and a collection box 5 on the front, and a coin processing unit 9 having a coin depositing unit 7 and a coin dispensing unit 8 on the front. The bill processing unit 6 and the coin processing unit 9 are integrated.

[0004] In the money handling apparatus 1, when the bill processing section 6 deposits a bill through the bill insertion slot 3, the bill is conveyed into the apparatus and stored in a mixed denomination. POS register 2
When there is a command to dispense as a change, for example, the required number of banknotes of the required denomination from the stored banknotes are paid out to the banknote outlet 4. The collection box 5 is used to store a banknote that is not used as a change when paying out the banknote, and that the banknote is discriminated. The coin processing unit 9 stores coins received from the coin depositing unit 7 by denomination, and when the POS register 2 issues a command to dispense, for example, as change, the required number of coins of the required denomination is output by the required number. It is paid out to Kinkoku 8.

Next, the internal structure of the bill processing unit 6 of the money handling apparatus 1 will be described. FIG. 9 is a side view showing the inside of the bill processing unit. In this figure, the left side is the front of the money handling apparatus 1, in which a bill insertion slot 3, a bill dispensing port 4, and a collection box 5 are provided.

At the downstream side of the bill insertion slot 3, there is provided a depositing roller 11 for drawing the deposited bills into the inside of the apparatus, and at the downstream side thereof, there is provided a depositing discriminating section 12 for discriminating the type of the deposited bills. Downstream of the deposit discriminating section 12, there is a storage 14 for storing and storing banknotes from above, and a vane is planted on the outer periphery on the front side to rotate the rear end of the banknotes conveyed to the storage 14. Roller 1 pressed down by
3 is provided, and a holding plate 15 is provided in the storage 14 so as to be swingable about a swing shaft 20. A supply roller 2 for sending out stored banknotes 10 is provided at a lower portion of the storage 14.
5. A dispensing section 16 for separating and sending out the fed bills one by one, a transport section 17 for transporting the fed bills, and a dispensing discriminating section 18 for determining a denomination of the dispensed bills are provided.
Downstream of the transport unit 17, a dispensing transport unit 19 that transports the fed banknotes to the banknote outlet 4, a collection transport unit 23 that transports the banknotes to the collection warehouse 5, and a circulation transport unit that transports the banknotes again to the storage 14. 24, a dispensing gate 21 for distributing to the circulating transport section 24 and the dispensing transport section 19, and a collection gate 22 for distributing to the circulating transport section 24 and the collecting and transporting section 23 are provided. Further, a sensor 26 for confirming the feeding of the bill is provided downstream of the feeding section 16.

Next, the operation of the bill processing unit will be described in detail along the bill transport route. The bill inserted from the bill insertion slot 3 is drawn in by the facing depositing roller 11, and the denomination of the deposited bill is performed by the depositing discriminating unit 12 located downstream thereof. Here, the banknote that cannot be distinguished is returned to the banknote insertion slot 3.

[0008] The bill which has been discriminated is conveyed, and the holding plate 1
5 are pushed up and arranged in order from the top of the storage 14. The banknotes 10 accumulated in the storage 14 are pressed by the pressing plate 15 at a position substantially facing the supply roller 25 at the center, and the rear end is pressed by the blade roller 13. As a result, the subsequent banknotes can be stably stacked without colliding with the already stored banknotes 10. Here, one end of the holding plate 15 is fixed to the swinging shaft 20 and is swingably supported, and holds the bill 10 only by its own weight.

At the time of withdrawal, the banknotes 1 accumulated in the storage 14
The feed roller 25 is fed rightward in the figure by rotation of the supply roller 25 in the direction of the arrow from below, and is separated one by one by the feeding unit 16 and fed. The fed banknotes are sent by the transport unit 17, and a denomination determining unit 18 provided on the way determines the denomination. As a result of the denomination discrimination by the dispensing determination unit 18, the bills to be dispensed pass through the dispensing transport unit 19 and are aligned and accumulated in the bill dispensing port 4. As a result of the denomination discrimination, for example, banknotes that do not need to be dispensed as change, such as ten thousand banknotes, operate the dispensing gate 21 and the collection gate 22, pass through the collection conveyance unit 23, and are aligned and collected in the collection box 5. . As a result of the denomination discrimination, the banknotes that cannot be discriminated or do not need to be dispensed operate only the dispensing gate 21, pass through the circulating transport unit 24, circulate again in the storage 14 and are accumulated.

[0010]

However, in the conventional storage 14 of the banknote processing unit 6, since the stacked banknotes are pressed from above by their own weight by the pressing plate 15, the following problems arise. Depending on the folded state of the banknote, the banknote may not be fed correctly at the time of dispensing simply by pressing the banknote by the weight of the holding plate 15 alone. The details will be described with reference to FIGS.

FIG. 10 is a view showing an example of a state of storing folded banknotes in a storage box. In the case of unbroken banknotes or several folded banknotes, the holding plate 15
The stacked banknotes can be pressed against the supply roller 25 only by the weight of the banknotes, so that there is no problem in feeding the banknotes.
However, as shown in FIG. 10, for example, when a large number of folded banknotes 61 are accumulated in a new bill,
Breaking may increase. As a result, the holding plate 1
With only the own weight of 5, the bill cannot be completely pressed against the supply roller 25, and a gap is generated between the lowest bill and the supply roller 25, so that the bill cannot be fed out.

Further, even when a large number of folded bills 61 are stacked, the load may be increased from the beginning so that the bills 61 can be pressed against the supply roller 25.
In that case, another problem arises.

FIG. 11 is a diagram showing a state in which bills are accumulated in a storage. If the denomination of the fed banknotes cannot be determined while feeding the stacked banknotes 10, the banknotes are circulated and re-stored in the storage 14. In other words, the operation of depositing (storing) banknotes is performed at the same time when the banknotes are paid out. For this reason, if the load applied to the banknotes is increased so that the banknotes can be pressed against the supply roller 25 even for a folded banknote, a stacking failure as shown in FIG. 11 may occur. is there. That is, the accumulation of the bills in the storage is such that the leading end of the conveyed bills enters between the already accumulated bills 10 and the holding plate 15, proceeds while pushing up the holding plate 15, and is accumulated on the bills 10. However, if the load for holding the bills is large, the leading end of the bills that have been conveyed may not be able to push up the holding plate 15 and may be jammed there. This is especially likely for weakened bills.

SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a banknote stacking / dispensing apparatus capable of reliably storing and feeding any banknote.

[0015]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention solves the above-mentioned problem. A supply roller that is disposed at the lower part of the banknote storage so as to abut against the lowermost banknote and feeds the stacked banknotes horizontally from below, and separates and separates the banknotes sent by the supply roller one by one. A bill provided with a bill separating and feeding section to be output, and a pressing plate fixed at one end to a swing shaft rotatably supported in the bill storage, and provided at the other end so as to face the supply roller. In the stacking and feeding device, when the supply roller sends out the banknotes stacked on the supply roller in the banknote storage to the banknote separation and feeding unit, a load is applied to the stacked banknotes from above by the pressing plate. To Bill stacking feeding apparatus characterized by comprising a load applying means for obtaining is provided.

According to such a bill collecting and feeding device,
In the banknote storage, when the supply roller sends out the stacked banknotes, the load applying unit applies a load to the holding plate holding the stacked banknotes, and urges the stacked banknotes toward the supply roller. . As a result, the lowermost bill strongly contacts the supply roller. Therefore, when the supply roller rotates and the friction material provided around a part of the outer periphery thereof comes into contact with the lower surface of the bill, the bill can be reliably sent to the bill separating and feeding section. The load applying means releases the load when the supply roller does not send out the bills, so that the bills can be accumulated in the bill storage box as before. Thus, even if a large number of folded banknotes are stacked, stable feeding can be performed without affecting stacking.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings, taking as an example a case where the present invention is applied to a storage for storing and storing bills in a bill processing unit.

FIG. 1 is an exploded perspective view showing an example of a load applying portion for a stacked banknote in a storage. The holding plate 15 for holding the banknotes accumulated in the storage is fixed to the swing shaft 20 and is integrated therewith. A pin 31 is fixed in the radial direction outside the holding plate 15 of the swing shaft 20. The load applying unit includes a torsion coil spring 32, a worm gear including a worm wheel 35 and a worm 37, and a motor 38.

Both ends of the torsion coil spring 32 are bent in the axial direction, and one fixed end 33 is connected to a worm wheel 35.
And the free end 34 at the other end is engaged with the pin 31. The torsion coil spring 32 and the worm wheel 35 are rotatably held with respect to the swing shaft 20. The worm wheel 35 obtains the driving force of the motor 38 via the worm 37.

FIG. 2 is an explanatory view of the assembly of the load applying section. 2, a torsion coil spring 32 is loosely inserted into one end of the swing shaft 20, and a worm wheel 35 is further rotatably held at the tip of the torsion coil spring 32. Worm wheel 35
The torsion coil spring 32
Is fixed, and the torsion coil spring 32 and its free end 34 rotate around the swing shaft 20 with the driving of the worm wheel 35.

Here, when the bill processing unit is performing the deposit operation and when the denomination of the fed bill fails,
The worm wheel 35 is at the return position (initial position), and at this time, the free end 34 of the torsion coil spring 32 is
It is not engaged with the pin 31 provided on the zero. That is,
The pressing plate 15 presses the banknotes accumulated and stored by its own weight.

On the other hand, the sensor 26 installed downstream of the payout unit 16 despite the fact that the banknotes are being paid out from the storage 14 in response to the payout command from the POS register.
If the delivery of the bill cannot be confirmed (see FIG. 9), the motor 38 is driven to rotate the worm 37 in the direction of the arrow shown in the figure, and the worm wheel 35 meshing with the worm 37 is moved in the direction of the arrow in the figure. Rotate to. This allows
The torsion coil spring 32 fixed to the worm wheel 35 also rotates with respect to the swing shaft 20, and the free end 34 of the torsion coil spring 32 contacts the pin 31 fixed to the swing shaft 20.

At this time, the rotation of the swing shaft 20 is restricted because the tip of the holding plate 15 contacts the supply roller 25 via the bill 10. By continuing the driving of the motor 38, the torsion coil spring 32 is twisted, a torque is applied to the pressing plate 15 by the reaction force of the spring, and the force for pressing the bill 10 against the supply roller 25 is increased. The motor 38 stops when the torsion coil spring 32 reaches a certain torsion angle.

Here, the stop position of the motor 38 is detected by
As described later, a load position detection sensor that rotates together with the swing shaft 20 detects the rotation position of the worm wheel 35, thereby detecting the torsion angle of the torsion coil spring 32,
The motor 38 is stopped at a predetermined twist angle.

As described above, by driving the motor 38 until the free end 34 of the torsion coil spring 32 comes into contact with the pin 31 and reaches a predetermined torsion angle,
Regardless of the amount of stored bills, that is, the twisting angle of the torsion coil spring 32 with respect to the holding plate 15 irrespective of the swinging position of the holding plate, the torque applied to the holding plate 15 can be made constant, and The pressing force becomes almost constant.

FIG. 3 is a view showing a state in which a plurality of folded and folded bills are pressed by the pressing plate. By pressing the folded bill 61 toward the supply roller 25 by the holding plate 15, the bill 61 is
The contact resistance between the paper currency and the supply roller 25 is increased, so that the banknote 61 can be more reliably sent out to the feeding unit 16.

Next, the sensor 2 downstream of the feeding section 16
After confirming the feeding of the bill in step 6, the motor 38 is rotated in the reverse direction to untwist the torsion coil spring 32, and the additional torque applied to the swing shaft 20 and the holding plate 15 is released.
Release the pressing force. Thereby, even if the fed banknotes are circulated due to the inability to discriminate, they do not affect the accumulation in the storage 14.

Next, the swingable range of the holding plate 15 will be described. FIG. 4 is a perspective view of a main part for explaining a swing range of the holding plate, and FIG. 5 is a side view of a main part for explaining a swing range of the holding plate. In FIG. 4, when the holding plate 15 a and the pin 31 a indicated by a dashed line are turned in the direction of the arrow, the pin 31 contacts the free end 34 of the torsion coil spring 32. Is the range in which the holding plate 15 moves by its own weight. As shown in FIG. 5, the storage range of the range θ1 from the position of the holding plate 15a when the banknote 10 in the storage 14 is empty to the position of the holding plate 15b when the banknote 10 is full, When the banknotes 10 in the storage 14 are manually collected and collected, this is a range in which the range θ2 up to the position of the holding plate 15c that lifts the holding plate 15 is combined.

Next, a part for detecting the stop position of the motor 38 when the worm wheel 35 is driven to rotate will be described. FIG. 6 is a side view of a main part of the worm wheel rotation range detecting mechanism. A return position detection sensor 41 is fixed to the frame 40 on which the swing shaft 20 is supported, and a load position detection sensor 42 is fixed to the pin 31 fixed to the swing shaft 20. Further, a detection hole 43 is formed in the worm wheel 35 so as to penetrate the worm wheel 35. The return position detection sensor 41 and the load position detection sensor 42 have a positional relationship such that the detection hole 43 moves when the worm wheel 35 is rotated by the motor 38. Then, the return position detection sensor 41
The load position detection sensor 42 includes a light-emitting unit and a light-receiving unit. When light emitted from the light-emitting unit is detecting light reflected on the end face of the worm wheel 35, the worm wheel 35 is located at a position to be rotated. Recognize that there is. When the light emitted from the light emitting unit passes through the detection hole 43 of the worm wheel 35 and the light receiving unit cannot detect the reflected light, the return position detection sensor 41 moves the worm wheel 35 to the return position ( (Initial position). The light emitted from the light emitting portion of the load position detection sensor 42 is detected by the detection hole 43 of the worm wheel 35.
When the light receiving unit cannot detect the reflected light after passing through the torsion coil spring 32,
It is recognized that the free end 34 has rotated by a predetermined twist angle after contacting the pin 31.

After the free end 34 of the torsion coil spring 32 contacts the pin 31, the worm wheel 35,
When the fixed end 33 of the torsion coil spring 32 is rotated by a predetermined torsion angle, the driving of the motor 38 is stopped, so that the pressing plate 15 which varies according to the amount of bills stored and stored in the storage 14 is arranged. Regardless of the position of the leading end, the torque applied to the holding plate 15 becomes constant, and a substantially constant pressing force of the bill can be obtained.

The operating condition of the motor 38 is confirmed by the sensor 26 provided downstream of the feeding section 16, and the feeding of the banknote is confirmed. However, if the banknote is not fed within a predetermined time, the banknote is not fed. And the motor 38 is driven. Here, the reason for waiting for a certain period of time is that if the already-fed banknotes have been circulated due to indiscernibility, the holding plate 1 will be closed before the circulation is completed.
When a load is applied to 5, as shown in FIG. 11, the holding plate 15 cannot be pushed up by the bill and a stacking fault occurs, so that at least the time until the circulation is completed is made to wait.

FIG. 7 is a side view of a main part showing another embodiment of the load applying part. In this figure, the holding plate 15
Is fixed to the swing shaft 20 and is configured to swing around the swing shaft 20. A coupler 51 is provided at one end of the swing shaft 20. The coupler 51 has a viscous fluid enclosed therein, for example, and generates a load torque according to the angular velocity. The external transfer of the coupler 51 is performed by a motor 52 by a driving force transmitting belt 53 such as a timing belt.
It is connected to the.

In order to increase the load on the stacked banknotes, the motor 52 is driven in the direction of the arrow to forcibly rotate the outer ring of the coupler 51 at a high speed. Can be generated in the direction in which is pressed against the supply roller, that is, a pressing force.

To release the load, the motor 52
May be stopped to stop the forced rotation of the coupler 51.
As a result, at the time of depositing (or circulating) into the storage, the angular velocity of pushing up the holding plate 15 with the bill is low, so that the resistance inside the coupler 51 is small, and the bill returns to pushing the bill almost only by its own weight.

[0035]

As described above, according to the present invention, during depositing and normal dispensing, the bill is pressed against the supply roller only by its own weight of the holding plate, and the reaction force of the spring or the internal resistance of the coupler only when the non-dispensing occurs. Thus, a load is applied to the pressing plate, and the bill is pressed against the supply roller to obtain a conveying force. As a result, it is possible to perform a stable payout until a large number of folded bills are stacked from the normal bills.
