Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a paper sheet feeding device for feeding paper sheets such as banknotes placed on a stage one by one, and more particularly to a device main body such as a batch storage in a banknote depositing / dispensing device. On the other hand, the present invention relates to a detachable paper sheet feeding device.

[0002]

2. Description of the Related Art Heretofore, a bill depositing / dispensing device has been put into practical use, which is equipped with a collective storage for storing bills of a plurality of denominations and being detachable from the main body of the device. By mounting this batch storage in the deposit / withdrawal device, the banknotes in the batch storage can be replenished in the deposit / withdrawal device, or conversely the banknotes in the deposit / withdrawal device can be collected in the batch storage to For convenience of handling.

In the collective storage, the bills for replenishment are placed on the stage, the uppermost portion of the bills is pressed against the feeding roller, and the feeding roller is rotated in this state to feed the bills to the depositing / dispensing device. I'm trying to put it out. For pressure contact with the feeding roller, for example, a step motor or a DC motor is rotated to move up the stage, and the bill on the stage is pressure-contacted with the feeding roller.

[0004]

However, in the above-mentioned conventional batch storage box, the pressure contact force of the stage with respect to the feeding roller when feeding the bills is set to a constant value by pushing up the feeding roller. The drive of the motor is stopped at a position where a constant pressure contact force is obtained. Thereafter, as the bill feeding operation is performed, the feeding roller is gradually lowered. When the feeding roller is lowered to a certain position, the motor is driven again to raise the stage, and the feeding roller is pushed up to return to a constant pressure contact force. However, when the amount of bills placed on the stage is large when the drive of the motor is stopped, the load due to the bill weight becomes larger than the friction load of the stage drive system, and the stage goes down. As a result, there is a problem in that the feeding roller and the bill are in poor contact with each other, and the feeding failure occurs.

[0005]

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention presses a sheet accumulated on a vertically moving stage and a feeding means and presses the feeding means to roll a sheet. The paper sheet feeding device for feeding out is provided with a braking means for braking the descending operation of the stage when a load of a predetermined amount or more is applied to the stage.

According to the present invention having the above-mentioned structure, when a large number of paper sheets are placed on the stage and a load larger than a predetermined value is applied to the stage, the braking means acts on the descending operation of the stage. Therefore, the poor contact between the feeding means and the paper sheets does not occur, and the feeding is performed well. Further, when the number of paper sheets on the stage is small, the descending operation of the stage is not braked, so that the pressure contact force with respect to the feeding means does not become too large, and the paper sheets are well fed.

Embodiments of the present invention will be described below with reference to the drawings. Elements common to the drawings are assigned the same reference numerals. FIG. 1 is a schematic side view showing a collective storage according to an embodiment of the invention, and FIG. 2 is a schematic rear view showing the collective storage according to the embodiment. In the present embodiment, as a paper sheet feeding device, a batch storage mounted on a bill depositing / dispensing device will be described.

In FIG. 1, pulleys 2a, 2b, 2c, 2d, 2e, 2f, 2g, 2h are provided on the side of the collective storage 1.
Are rotatably arranged, and the belt 3 is wound around these pulleys. Pulleys 2a, 2b, 2c, 2d,
2e, 2f, 2g, 2h are toothed pulleys, and the belt 3 is also toothed. The belt 3 is rotationally driven by a driving unit (not shown), and the stage 4 is fixed.
The stage 4 mounts the banknotes 5 and moves up and down by driving the belt 3. The belt 3 is similarly arranged on the opposite side of the collective storage 1, and the stage 4 is supported from both sides. A gear 6 is attached coaxially with the pulley 2e. The gear 6 rotates integrally with the pulley 2e, and thus also rotates integrally with the belt 3. A DC motor 26 is connected to the pulley 2h, and the motor 26 rotates the pulley 2h to rotationally drive the belt 3 and move the stage 4 up and down.

A shaft 7 is provided on the side of the housing of the collective storage 1.
And a bracket 8 and a gear 9 are rotatably attached to the shaft 7. A gear 10 that meshes with the gear 9 is rotatably attached to the bracket 8. The gear 10 revolves around the gear 9 by the rotation of the bracket 8 and can mesh with the gear 6. The end 8a of the bracket 8 is biased upward by a spring 11. The rotation of the bracket 8 in the clockwise direction is locked at a position shown in the drawing by a stopper (not shown). A shaft 12 is fixed to the side of the housing of the collective storage 1, and a gear 13 is rotatably attached to the shaft 12. A torque limiter 14 is also mounted on the shaft 12, and the torque limiter 14 includes a gear 13
If a certain load is applied to the rotation of the gear 13 when it rotates in the counterclockwise direction, a certain load is applied to the rotation of the gear 13, thereby braking the rotation. When the gear 13 rotates in the clockwise direction, the torque limiter 14 does not load the rotation of the gear 13. The gear 13 always meshes with the gear 9.

A delivery roller 15 is rotatably provided above the stage 4. The feeding roller 15 is pressed downward by a spring 16 and is vertically moved within a certain range. The feeding roller 15 is a roller for feeding the banknote 5 on the stage 4, and a separating roller 17 and a reverse roller 18 that is in pressure contact with the separating roller 17 are provided on the left side of the feeding roller 15. Separation roller 17 and reverse roller 18
Separates the fed-out banknotes one by one. A guide 19 for guiding the banknotes 5 is arranged near the reverse roller 18.

In FIG. 2, an actuator 20 is provided on the rear surface of the collective storage 1 so as to be rotatable around a fulcrum 21. The actuator 20 has a lever portion 22,
A roller 23 is rotatably attached to the upper part. The actuator 20 is biased counterclockwise by a biasing means (not shown), and is locked at the position shown. The lever portion 22 projects laterally from the housing of the storage case 1, and the tip portion thereof is one end 8 of the bracket 8 shown in FIG.
a is engaged with the upper part. On the back surface of the storage case 1, a mounting hole 24 for mounting the storage case 1 on the main body device is formed, and the roller 23 is arranged so as to partially cover the mounting hole 24.

Next, the operation of the present embodiment will be further described with reference to FIGS. FIG. 3 is a schematic rear view showing the operation of the actuator of the embodiment, and FIG. 4 is a schematic side view showing the meshing of the gears of the embodiment.

The collective storage 1 is mounted on a main body device (not shown). When the collective storage 1 is not attached to the main body device, as shown in FIG. 1, the gear 6 is not meshed with the gear 10, so that the stage 4 can be moved up and down relatively easily. Then, the banknote 5 is placed on the stage 4 with the stage 4 lowered. In this state, the collective storage 1 is attached to the main body device.

A mounting protrusion is formed on the main body device, and the protrusion is inserted into the mounting hole 24 of the collective storage 1. FIG. 3 shows a state in which the protrusion 25 is inserted. Protrusion 25
When the roller is inserted, the roller 23 rotates and the mounting hole 24
Evacuate from As a result, the actuator 20 moves the fulcrum 2
The lever portion 22 pushes down one end 8a of the bracket 8 by rotating clockwise about 1.

In FIG. 4, when one end 8a of the bracket 8 is pushed down, the gear 10 revolves around the gear 9,
It meshes with the gear 6. By this meshing, the gear 6, the gear 10, the gear 9, and the gear 13 mesh with each other in this order, and the rotation can be transmitted. On the other hand, after the collective storage 1 is attached to the main body device, the motor 26 is driven in the direction of raising the stage 4, and the belt 3 is rotationally driven. The belt 3 causes the stage 4 so that the banknote 5 on the stage 4 contacts the feeding roller 15. Even after the contact, the stage 4 is further raised, and the motor 26 is stopped when the stage 4 is raised to a position where the pressure contact force between the bill 5 and the feeding roller 15 is constant (preset). In this state, the bill 5 can be fed out.

When many banknotes 5 are placed on the stage 4, the load on the stage 4 increases due to the weight thereof. The load applied to the stage 4 when the motor 26 is stopped is transmitted from the belt 3 to the gear 13 via the gear 6, the gear 10, and the gear 9. A torque limiter 14 is provided coaxially with the gear 13, and the torque limiter 1
When the gear 13 tries to rotate in the counterclockwise direction and a load of a certain amount or more is applied to the gear 13, the rotation of the gear 4 is braked, so that the braking action is transmitted to the belt 3 in reverse. As a result, even when a large amount of banknotes 5 are placed on the stage 4, the stage 4 does not descend, and therefore no gap is created between the banknote 5 and the feeding roller 15.

When the feeding roller 15 is rotationally driven in this state, the uppermost banknote 5 is fed, separated into one sheet by the separating roller 17 and the reverse roller 18, and fed to a main body device (not shown). The banknote 5 is a feeding roller 15
Since they are in contact with each other with an appropriate pressure contact force, the feeding is performed well.

When the number of banknotes 5 on the stage 4 is reduced by repeating the feeding, the feeding roller 15 is gradually lowered. When the stage 4 descends to a predetermined position, a constant pressure contact force cannot be obtained. In this case, the motor 26 is driven, the stage 4 is raised again, and the feeding roller 15 and the bill 5 are separated from each other. The constant pressure contact force is obtained. After that, the driving of the motor 26 is stopped and the feeding of the banknote 5 is restarted.

By repeating the above operation, the banknotes 5 are sequentially drawn out one by one. When the banknotes 5 on the stage 4 become small, the load applied to the gear 13 when the motor 26 is stopped,
That is, the load on the torque limiter 14 is reduced. The torque limiter 14 does not exert a braking action when a load below a certain level is applied. In this case, therefore, the stage 4
Braking does not work for the descending motion of. Therefore, on the stage 4, the weight of a small amount of bills 5 and the feeding roller 15
Is applied as a load, and this load is an appropriate value for feeding the bills 5, so that the bills 5 can be fed well when the bills 5 are small.

When the collective storage 1 is removed from the main unit,
The protrusion 25 shown in FIG. 3 is removed from the mounting hole 24, and the actuator 20 returns to the position shown in FIG. 2, that is, the original position. When the actuator 20 returns, the bracket 8 also returns to the original position shown in FIG. 1, and the gear 6 and the gear 10 are disengaged. As a result, the torque limiter 14 is separated from the belt 3, and the stage 4 moves down without being braked.

The present invention is not limited to the above embodiment, but various modifications can be made. For example, in the above embodiment, only one torque limiter is provided,
Two torque limiters are provided, and the load values at which the torque limiters start the braking action are set separately. If there are many banknotes 5 on the stage 4, 2
One torque limiter brakes when the number of banknotes 5 becomes slightly small, and one torque limiter brakes when the number of banknotes 5 becomes small. By doing so, the pressure contact force between the bill 5 and the feeding roller 15 becomes more appropriate, and the bill 5 is more favorably fed.

Further, the present invention is not limited to a batch storage box for storing banknotes, but may be applied to other devices as long as it is a device for feeding sheets placed on a stage in order from the top. Needless to say.

[0023]

As described in detail above, according to the present invention, the braking means is provided for braking the descending operation of a stage on which a bill is placed when a load of a predetermined amount or more is applied to the stage. Even when a large amount of banknotes are placed on the stage, the banknotes can be delivered well.
