Description

[Detailed explanation of the invention] (a) Industrial application field This invention is applicable to, for example, automated teller machines used in banking, where banknotes are inserted for deposits and banknotes are used for withdrawals. The present invention relates to a banknote handling device that accepts and discharges paid banknotes.

(B) Prior Art When the automatic teller machine of the above example accepts deposited banknotes in bulk, a receiving and accumulating unit is required to take in and verify the banknotes one by one.
Further, when dispensing banknotes all at once, a discharging/accumulating section is required to collectively accumulate the banknotes conveyed one by one.

When the above-mentioned bulk acceptance of deposited banknotes and bulk discharge of withdrawn banknotes are performed using a single deposit/withdrawal port, using this deposit/withdrawal port itself as the above-mentioned intake/accumulation section or discharging/accumulating section means that each accumulation section is This is not possible due to the existence of a mechanism for configuring the banknotes, so a banknote stacking section that also serves as an intake/accumulation section and a discharge/accumulation section is constructed below the deposit/withdrawal port, and these deposit/dispatch ports and bill stacking section are constructed. The banknotes are clamped and conveyed between the banknotes and the banknotes.

(c) Problems to be solved by the invention By the way, when deposited banknotes and disbursed banknotes are handled in one banknote stacking section as described above, this banknote stacking section and the banknote dispensing section or ,
The banknote conveyance path that connects the banknote collection units is complicated, and there are many sorting plates that change the direction of banknote conveyance, so the banknote conveyance position becomes slanted and disordered. Banknotes often get jammed in the conveyance path due to turbulence, especially when incoming banknotes are circulated as outgoing banknotes. Since there are various factors that disturb the posture of banknotes, the above-mentioned jam during transportation has been noticeable.

The object of this invention is to provide a banknote processing apparatus that can eliminate banknote conveyance jams by cutting off the source of disturbance in the banknote conveyance posture.

(d) Means for solving the problem This invention has a fixed piece located in the width direction of the input banknotes of the clamp that clamps the input banknotes and conveys them to the lower banknote stacking section. A regulating plate is pivotally attached to a position for regulating the width direction of the banknote by a rotation shaft so as to be rotatable between a regulating position and an open position, and the regulating plate is attached to the regulating position when the clamp is located at the deposit/withdrawal port. The bill processing device is characterized in that it is provided with a biasing means that biases the regulation plate to the open position when the regulation plate is moved away from the deposit/withdrawal port.

(E) Function The banknote handling device of this invention permits the insertion of banknotes by restricting the width of the banknotes by the biased regulation plate when the banknotes are inserted into the deposit/withdrawal port. After the banknotes are inserted, the deposited banknotes are held by clamps and conveyed to the banknote stacking section at the bottom, and the restrictions in the width direction of the banknotes are released in this conveyance and the banknote stacking section.

Moreover, the banknotes to be paid out in the banknote stacking section are stacked without restricting the width direction of the banknotes by the regulating plate, and are conveyed to the deposit/withdrawal port.

(f) Effects of the invention According to this invention, by regulating the position of the inserted banknotes in the width direction with a regulating plate provided on the clamp,
It is possible to cut off the root cause of disturbance in the conveyance posture of banknotes.

In other words, although customers put the bottom side of the banknotes on the table two or three times to line them up and throw them in, they simply align them by hand in the width direction of the banknotes, and it is common for them to throw them in unevenly. be. By regulating this with an energized regulation plate, the uneven banknotes are realigned again, and the width direction of the banknotes is aligned.
Factors that disrupt internal banknote transport are removed, and smooth banknote transport is achieved.

Furthermore, since the above-mentioned regulation plate is open when taking in (accumulating) disbursed banknotes, the banknotes do not get caught on the regulation plate during stacking, and banknotes can be stacked smoothly without any jams.

Thereby, the deposited banknotes are accumulated in the banknote stacking section 2 while being received by the receiving plate 7.

Next, by turning on the second solenoid 58, the lever 55 is pulled, the support member 50 is pushed out, and the pressing plate 46 presses the deposited banknotes against the guide plate 47.

Note that this pressing force is the acting force of the spring 57.

Next, when the second motor 45 is turned on, the operating cam 38 rotates, and this rotation causes the operating lever 36 to operate the operating portion 23 of the receiving plate 7, thereby opening the receiving plate 7. As the second motor 45 continues to be turned on, the rotation of the operating cam 38 is stopped due to the stopper piece 39 coming into contact with the stopper pin 40, but its posture is maintained by the torque limiter. The open state of the receiving plate 7 is maintained.

After waiting for the time for the movement of the press plate 46 and the receiving plate 7 to complete, the third motor 78 is turned on to start taking in the banknotes 6.

By driving the third motor 78, the take-in roller 61 rotates in the take-in direction. Note that although the feed roller 69 and the auxiliary roller 75 also rotate at the same time, the feed roller 69 does not act.

By the rotation of the above-mentioned taking-in roller 61, the deposited banknotes in the banknote stacking section 2 are taken in one by one under the control of the gate roller 63, and sent out one by one by the nipping roller 65 and the taking-in guide plate 66.

Such banknotes are taken in sequentially and the second
When the sensor 81 detects that there are no more banknotes, the third motor 78 is stopped, and the taking-in operation of the taking-in roller 61 is stopped after the time has elapsed for the last taken-in banknote to be completely taken in.

When the second motor 45 is stopped, the operating cam 38 is returned to its original position by the force of the spring 41, so the operating lever 36 is also returned, and the receiving plate 7 receives the bill 6 by the spring 22. returned to position.

Furthermore, when the second solenoid 58 is turned off,
The support member 50 is pulled by the spring 52, and the pressing plate 46 returns to its original position, completing the process of accepting deposited banknotes.

Next, the withdrawal process will be explained.

When the second solenoid 58 is turned on, the pressing plate 46 moves toward the guide plate 47 and is pressed by the action force of the spring 57.

After waiting for the completion of the movement of the press plate 46, the third motor 78 is turned on, and this turns on the feed roller 69,
The auxiliary roller 75 is rotated in the feeding direction.

Note that the intake roller 61 is also rotated, but the receiving plate 7
It does not work because it is in a position that forms the bottom.

The dispensing banknotes that are fed out from an appropriate dispensing banknote dispensing unit and guided to the feed roller 69 are further stiffened by the feed roller 69 and the curling roller 71, and then transferred to the banknote stacking unit 2. sent to.

At this time, the pressing plate 46 is in a pressed state, but is inserted between the pressing plate 46 and the guide plate 47 by forced feeding of the auxiliary roller 75.

Furthermore, as the banknotes 6 are fed in sequence, the upper edges of the banknotes that have already been stacked are pressed against the pressing plate 46 by the projections 72 of the curling rollers 71.
Since it is pushed to the side, it becomes easy to feed the next bill.

When the feeding of the predetermined bill to be paid is completed, the third sensor 82 detects this, the third motor 78 is stopped, and the feeding roller 69 and the auxiliary roller 75 are stopped.

Then, by turning off the second solenoid 57, the press plate 46 returns to its original position, and the press plate 4
After waiting for the completion of the return of the motor 6, the first motor 33 is driven to rotate normally.

This drive causes the clamp 8 to move upward, and when the lower limit release cam 19 separates from the operation piece 17 of the movable piece 11 of the clamp 8, the clamp 8 clamps the dispensed banknotes in the banknote stacking section 2. It can be transported upwards.

When the clamp 8 reaches the upper limit position and the first switch 31 is operated, the forward rotation control of the first motor 33 is stopped, and the upward movement of the clamp 8 is stopped.

When the clamp 8 reaches the upper limit position, the lock piece 28
locks the connecting pin 14, and the upper limit release cam 18 releases the banknote from the clamp 8 and is received by the left and right receiving plates 7, and the top of the banknote protrudes from the deposit/withdrawal port 1. You will have to wait in that state.

At this time, the regulation plate 83 is also moved to the regulation position, but this does not affect the dispensed banknotes in any way.

When a bill is withdrawn from the deposit/withdrawal port 1, the first sensor 80 detects this, and based on this detection, the first solenoid 30 is turned on, the lock piece 29 is unlocked, and the first motor 33 is turned on. By controlling the reverse direction, the clamp 8 is moved downward.

When the clamp 8 reaches the lower limit position, the lower limit release cam 19 releases the clamp 8, and the second switch 32 is operated, the reverse rotation control of the first motor 33 is stopped, and the downward movement of the clamp 8 is stopped. , the first solenoid 30 is turned off, and the dispensing banknote feeding process ends.
