Description of Operation of Dispensing Port Mechanism “Dispensing Operation (Operation for Dispensing Normally Conveyed Bills to Customer)” (1) First, as shown in FIG.
In a state where the 46 detection pieces 46A are detected, the transfer bill is conveyed to the stacking unit 100 of the dispensing port 1 by the transfer mechanism. That is, when the sensor 57 is detecting the detection piece 46A of the link 46, the banknotes can be transported and accumulated.

At this time, the solenoid 17 (see FIG. 5) is turned off.
Thereby, as shown in FIGS. 1 and 5, the distal end of the regulating plate 11 holds the bottom plate 2 to prevent the dispensing port 1 from rotating.

Normally, when bills are transported by the transport mechanism, this state (standby / stacked state) is maintained.

(2) When the banknotes of the specified number of banknotes to be dispensed have been normally accumulated, the motor rotation by the motor shaft 45 is started until the detection piece 48A fixed to the link 48 is detected by the sensor 59. Then, the motor shaft 45 is rotated clockwise in FIG.

(3) When the motor shaft 45 rotates clockwise in FIG. 2, the link 48 rotates about the shaft 50, whereby the link 54 is moved through the link 52 to the second position about the shaft 27. Rotating in the clockwise direction in the drawing, the pin 55 located at the end thereof descends.

(4) The link whose rotation (fall) in the clockwise direction in FIG.
28A can be rotated clockwise, whereby the clamp roller 25 provided at the distal end of the link 28A / 28B comes close to the bottom plate 2 and the clamp belt 10, and finally the clamp Roller 25 and clamp belt 10
The bills to be dispensed are clamped between (see FIG. 3). In addition, as the clamp roller 25 rotates clockwise, the guide plate 31 is pushed by the shaft 26 so as to approach the bottom plate 2, and the stacked bills are sandwiched between the bottom plate 2 and the guide plate 31.

(5) By continuing to rotate the motor shaft 45 in the clockwise direction in FIG.
When the rotation is detected, the rotation of the motor shaft 45 is stopped.

(6) Next, as shown in FIG. 5, the motor of the motor shaft 41 is rotated, and the link 40 provided on the motor shaft 41 is rotated counterclockwise in FIG.

Thereby, the counterclockwise turning force of the motor shaft 41 is transmitted to the arm 35 via the link 50 and the link 38, and the arm 35 is rotated counterclockwise about the shaft 36,
The shutter 34 located at the tip of the arm 35 is opened.

When the motor 44 is continuously driven and the sensor 44 detects the detecting piece 42B of the link 40, the driving of the motor shaft 41 is stopped and the shutter 34 is kept open.

(7) As described above, the shutters 34 are opened in a state where the banknotes stacked in the stacking unit 100 of the dispensing port 1 are clamped by the clamp belt 10 and the clamp roller 25. Even if the wind blows when trying to remove the stacked banknotes, the stacked banknotes can be extracted in a stable state without being blown off. When the accumulated bill is taken out, the clamp belt 10 and the clamp roller 25 are both idle (the clamp belt 10 is in a state where the load on the motor shaft 63 is not applied by the one-way clutch 80 (see FIG. 6)). There is no resistance when extracting the

When the banknote is taken out by the customer, as shown in FIG.
Until 42A is detected, the motor shaft 41 is rotated counterclockwise in FIG. 5, thereby rotating the shutter 34 to the position shown by the solid line and closing the shutter 34. Thereafter, the motor shaft 45 is rotationally driven counterclockwise from the position shown in FIG. 3, and this driving is continued until the sensor 57 detects the detecting piece 46A of the link 46. And the guide plate 31 are arranged at the standby position shown in FIG.

The pulley 85 rotates, and the transport belt 62 is driven in a direction of transporting the banknote from the stacker 86 to the dispensing port 1.

Each pulley of the conveyor belt 62 is rotatably supported by the shaft so that all the conveyor belts 62 (83 and 84) follow when the shaft 68 rotates. The one-way clutch 69 transmits a rotating force to the shaft 68 only when the motor shaft 63 rotates forward, and when the motor shaft 63 rotates in the reverse direction in the arrow (d) direction, the one-way clutch 69 rotates in one direction. The clutch 69 idles and does not transmit rotational power to the shaft 68. When the motor shaft 63 rotates forward in the direction of the arrow (C), the pulley 67, the timing belt 82, the pulley
At this time, the one-way clutch 80 idles and the forward drive of the motor shaft 63 is not transmitted to the shaft 4.

Rejection operation in the transport mechanism If an abnormality (such as double feed) occurs during the transport of the dispensed banknote by the transport belt 62, the feeding roller 61, and the kick-out roller 60, the banknote is fed by the number of withdrawal commands to the stacking unit 100. After the transfer, the bill in the dispensing port 1 is rejected by the reject unit 88
I am trying to drop it.

Specifically, after the dispensing port mechanism is operated by the reject command, the bill is clamped to bring the bill into an upright state (this operation is described above), and then the motor shaft 63 is rotated in the reverse direction in the arrow (d) direction. Start moving.

When the motor shaft 63 rotates in the reverse direction, the seventh
Since the electromagnetic clutch 75 shown in the figure cuts off the transmission of the rotational power from the gear 73 to the shaft 74, the kicking roller 60 does not rotate, and the rotation of the feeding roller 61 is completely stopped by the brake 77A. become. When the motor shaft 63 rotates in the reverse direction, the one-way clutch 69 enters the idle state, so that the transport belt 62 is not driven when the motor shaft 63 rotates in the reverse direction.

On the other hand, when the motor shaft 63 rotates in the reverse direction, the one-way clutch 80 transmits its driving force to the shaft 4,
The clamp belt 10, which clamps the reject bill in an upright state, is driven toward the reject portion 88 of the stacker 86 via the pulley 7, and drops the reject bill downward.

Jumping-out banknote return operation After a dispensing banknote is fed, a part of the succeeding banknote may be bitten by the feeding roller 61 side. If the stacker 86 is pulled out of the frame 101 in this state, there is a possibility that the jammed bills may be damaged.

To prevent it, before removing the stacker 86,
Normally, the motor shaft 63 shown in FIG. 6 is reversely driven in the direction of the arrow (d) to reverse the kick-out roller 60 and the pay-out roller 61 to return the popped-out bills to the stacker.

At this time, the electromagnetic clutch 75 shown in FIG.
The rotational power from the gear 73 to the shaft 74 is set to be transmitted,
Further, the brake 77A releases the rotation restriction of the shaft 77. Further, the pop-out bill return operation may be performed when the opening of the front door (not shown) of the frame 101 is detected in order to take out the stacker 86.

As described above, the dispensing operation from the stacker 86 to the stacking unit 100, the rejection operation of the banknotes stacked in the stacking unit 100, and the operation of returning the banknotes jumping out of the transport path to the stacker 85 are all performed by one motor. (Motor shaft 63).

In the rejection mechanism of the bill dispensing machine configured as described above, the shaft 27, the link 46, the roller 47, the link 48, the long hole 49, the shaft 50, the pin 51, the link 52, the pin 53, the link 54, and the pin The link mechanism is constituted by 55, the shaft 27, the link 46,
Roller 47, link 48, slot 49, shaft 50, pin 51, link 5
2, the pin 53, the link 54, and the pin 56 constitute a rotation mechanism.

[Effects of the Invention] As described above in detail, according to the reject mechanism of the banknote dispensing machine shown in the present invention, the dispensing port mechanism is provided with the stacking unit for temporarily stacking the banknotes fed by the transport mechanism. Therefore, an effect is obtained that the overall configuration can be made smaller and more compact as compared with a conventional device of a type in which an integration unit is separately provided.

Further, in the dispensing port mechanism, the driving force transmitting means causes the clamp roller to approach the banknote in the direction of clamping the banknote, and the end of the rejected banknote to be stacked in the stacking section while the banknote is clamped by the clamp roller. And the rotating operation of the stacking unit for turning the stacking unit in the direction of the rejecting unit in the stacker is performed by the driving force of one driving motor, so that only one driving motor is required for these operations. . In addition, since the above two operations are switched according to the rotation range of the driving force transmitting means, the operation can be switched with a simpler structure. Therefore, an effect is obtained that the overall structure can be further simplified.
