2. Description of the Related Art FIG. 3 shows an example of a recycle building validator equipped with a banknote batch payout apparatus. The banknote collective dispensing device 16 is provided at the center of the recycle building validator 1, and the payout conveyor belts 4 arranged vertically above and below the recycle building validator 1.
3 and a guide plate 44, and a collective holding section 41 is defined therebetween. The batch holding section 41 has an inlet side connected to the payout conveyance path 13 and an outlet side connected to the bill payout port 9.

The guide plate 44 comprises a pair of left and right sides (only one on the near side is shown) and is configured to move up and down between a lower standby position (solid line position) and an upper payout position (two-dot chain line position). Have been. The pay-out conveyance belt 43 is also configured as a pair of left and right corresponding to the guide plate 44 (only one near side is shown). Then, in a state where the guide plate 44 is lowered to the standby position, the banknotes A are fed one by one from the payout conveyance path 13 to the collective holding unit 41, and a predetermined number of the banknotes A are stacked on the guide plate 44. Rises to the dispensing position and banknote A
The bill A is discharged from the bill payout port 9 in a lump as the payout belt 43 is operated.

On the other hand, the reject device 17 includes the guide plate 44, a reject holding portion 42 disposed below the guide plate 44, an upper standby position (solid line position), and a lower reject position (two-dot chain line). And a reject stack plate 45 that can be moved up and down between the positions. The reject device 17 moves the banknote A between the guide plates 44, 44 by lowering the reject stack plate 45 after the guide plate 44 rises, for example, when the banknote A is sent to the batch holding unit 41 in an overlapping manner. Is passed from the batch holding unit 41 to the reject holding unit 42 and held.

FIGS. 4 and 5 show a reject stack plate 45 and a conventional drive mechanism for driving the same. The drive mechanism 101 includes first and second link levers 86a and 86b rotatably connected to each other via a center connecting portion 85. A torsion coil spring 87 that constantly urges both link levers 86a and 86b toward the contracting side (the direction of arrow C in FIG. 5) is attached near the connecting portion 85.

The first link lever 86a has a rear end portion rotatably connected to the reject stack plate 45 and a front end portion slidably and rotatably engaged with the fixed guide slot 88. . Also, the second link lever 86
b is rotatably supported by a fulcrum 89 at a portion behind the connecting portion 85, and a front end portion is slidably and rotatably engaged with a guide elongated hole 90 formed in the reject stack plate 45. The rear end portion is in contact with the crank pin 92a of the pulley gear 92 from above while being urged by the torsion coil spring 87.

The pulley gear 92 is connected to the payout stack motor 81 via an intermediate gear 93 and a one-way drive mechanism 94, etc.
Is rotated in the direction of arrow B in the drawing, while rotation of the pulley gear 92 in the reverse direction is controlled by the one-way driving mechanism 94.
It is locked by. Note that the payout stack motor 81 is connected to the guide plate 44 via another one-way driving mechanism (not shown), and drives the guide plate 44 during reverse rotation. That is, the payout stack motor 81 is commonly used as a drive source for the reject stack plate 45 and the guide plate 44. Reference numerals 52 and 53 in the drawing are an upper limit sensor and a lower limit sensor for detecting whether the reject stack plate 45 is at the standby position and the reject position, respectively.

According to the reject device 17, in the standby state shown in FIG.
Since a is located at the bottom dead center, the first and second link levers 86a and 86b are in a contracted state,
The reject stack plate 45 is located at the upper standby position. In this state, when the state in which the bill A is sent from the payout conveyance path 13 to the collective holding unit 41 and the bill A is sent while being overlapped is detected, the payout stack motor 81 is rotated forward by a predetermined angle, and The pulley gear 92 is rotated counterclockwise via the one-way drive mechanism 94 and the intermediate gear 93 until the crank pin 92a is located slightly before the top dead center in FIG.

Accordingly, the second link lever 86b is
The first and second link levers 86a, 86b extend downward by being pushed up by the crank pin 92a and rotating counterclockwise around the fulcrum 89 against the spring force of the torsion coil spring 87, Along with this, the reject stack plate 45 is lowered to the reject position shown in FIG.

After the reject operation, the payout stack motor 81 is rotated forward by a predetermined angle, so that the pulley gear 9 is rotated.
2 rotates counterclockwise until the crankpin 92a returns to the bottom dead center beyond the top dead center, and returns to the angular position in FIG. Accordingly, the first and second link levers 86
a, 86b shrink, the reject stack plate 4
5 rises to the standby position and returns to the standby state.

[0011]

However, in the above-described reject device 17, when the crank pin 92a returns from the top dead center to the bottom dead center, the pulley gear 92 moves the second link lever 8
By receiving the spring force of the torsion coil spring 87 downward through 6b, the torsion coil spring 87 rotates while being accelerated, so that it is easy to overshoot beyond the bottom dead center. Once this overshoot occurs, the pulley gear 92 cannot return to the bottom dead center due to the action of the one-way drive mechanism 94,
Since the reject stack plate 45 stops at a position considerably lower than the standby position and protrudes into the narrow batch holding unit 41, a problem such as jamming occurs when the banknote A is sent to the batch holding unit 41. Would.

In order to solve such a problem,
As shown in FIG. 6, a positioning recess 96 is formed on the back surface of the pulley gear 92, a leaf spring 97 having a positioning projection 97a is provided, and the positioning recess 9 is formed at the bottom dead center of the pulley gear 92.
6 is engaged with the positioning projection 97a,
It is also known to position the pulley gear 92 at the bottom dead center. However, since the mechanical load varies from device to device and the spring characteristics of the leaf spring 97 also vary, it is extremely difficult to adjust the spring load. Since the change occurs, it is difficult to stably stop the reject stack plate 45 near the standby position.

SUMMARY OF THE INVENTION The present invention has been made in order to solve such a problem, and has a simple structure, and a rejection device for a banknote batch dispensing device capable of reliably and stably stopping a reject stack plate at a standby position. It is intended to provide a device.

[0014]

In order to achieve this object, a rejection device for a banknote batch dispensing device according to the present invention is provided with a motor, a rotating body having an eccentric crankpin, and a rotating body provided between the motor and the rotating body. A one-way drive mechanism that rotates the rotating body during normal rotation of the motor and locks the rotating body in the opposite direction, and is rotatably connected to each other at a central connecting portion. At the upper position, a pair of pantograph-shaped pantographs that have a horizontally long cam groove that engages with the crankpin of the rotating body with play and that is driven by the rotation of the rotating body through this cam groove to expand and contract in the vertical direction. The link lever and the lower end of the pair of link levers are rotatably attached to each other, and the upper standby position for accepting bills downward as the pair of link levers expands and contracts. And a reject stack plate that can be moved up and down between a lower position and a lower reject position for rejecting the accepted bills, and a spring that biases the pair of link levers toward the standby position. It is characterized by.

According to this reject device, in the standby state, the crank pin of the rotating body is located at the bottom dead center and the pair of link levers are in the contracted state, so that the reject stack plate is located at the upper standby position. Banknotes are received in the space below the reject stack plate. When a state in which bills are sent in an overlapped manner is detected, the motor rotates forward by a predetermined angle, so that the rotating body rotates by a predetermined angle in a predetermined direction via a one-way drive mechanism. Accordingly, one of the link levers is pushed up by the crank pin via the upper edge of the cam groove and pivots against the urging force of the spring, so that the pair of link levers extend downward and the reject stack The board descends to the lower reject position and rejects the bill downward.

Thereafter, when the motor rotates forward by a predetermined angle again, the rotating body rotates by a predetermined angle in the same direction as described above, and the crankpin moves from the top dead center to the bottom dead center. When the crank pin exceeds the top dead center, the crank pin is pushed downward via the upper edge of the cam groove of one of the link levers by the biasing force of the spring. On the other hand, since the rotating body is freely rotatable in this direction, the crank pin comes into contact with the lower edge of the cam groove, whereby the rotating body is braked. Then, at the next timing, the upper edge of the cam groove comes into contact with the crank pin again and presses it with the urging force of the spring, and the crank pin comes into contact with the lower edge of the cam groove again to rotate. The body is braked. In this way, when the rotating body returns to the bottom dead center, the crank pin is repeatedly braked by the lower edge of the cam groove, so that the rotating body does not greatly overshoot the bottom dead center and the vicinity of the bottom dead center Stop surely. Therefore, the reject stack plate can be reliably stopped near the standby position.

Further, as described above, since the rotating body is stopped at the bottom dead center by the braking by the lower edge of the cam groove, for example, as the use of the device progresses, the dimensional relationship and the like are reduced due to the wear of the cam groove and the crankpin. Even if the mechanical load changes, the reject stack plate can be stably stopped near the standby position without being affected by the change.
Further, this reject device can be simply configured by simply forming a cam groove in a link lever of an existing device.

2 and hold it.

FIGS. 1 and 2 show the reject stack plate 45 and the drive mechanism 84 thereof. Since the basic structure of the drive mechanism 84 is the same as that of the conventional drive mechanism 101 shown in FIGS. 4 and 5, the same components will be described using the same reference numerals. I do. The drive mechanism 84 includes first and second pantograph-shaped first and second pantographs rotatably connected to each other at a center connection portion 85.
Link levers 86a and 86b. Between the link levers 86a and 86b, near the connecting portion 85,
A torsion coil spring 87 (spring) is attached,
The link levers 86a and 86b are retracted, that is, as shown by an arrow C in FIG.
The latter 86b is constantly biased clockwise.

The first link lever 86a has a rear end rotatably connected to the reject stack plate 45 and a front end slidably and rotatably engaged with an immovable guide slot 88. . The second link lever 86b is
A portion behind the connecting portion 85 is rotatably supported by a fulcrum 89, and a front end portion is slidably and rotatably engaged with a guide long hole 90 formed in the reject stack plate 45. . The rear end of the second link lever 86b is branched in a forked shape, and a space between the branched portions is a laterally long cam groove 91.

A crank pin 92a of a pulley gear 92 (rotary body) is engaged with the cam groove 91. The diameter of the crank pin 92a is slightly smaller than the width of the cam groove 91, so that the crank pin 92a is engaged with the cam groove 91 with a little play. The rim 91a is in contact with the crank pin 92a, and is constantly pressed. Also,
The upper edge 91a of the cam groove 91 is formed with a stepped portion 91c that functions as a positioning stopper that comes into contact when the crank pin 92a reaches the bottom dead center, and correspondingly faces the stepped portion 91c. The lower edge 91b has a shape that escapes downward.

The pulley gear 92 is connected to the payout stack motor 81 (motor) via an intermediate gear 93 and a one-way drive mechanism 94, and is driven to rotate in the direction of arrow B in FIG. On the other hand, the rotation of the pulley gear 92 in the reverse direction is locked by the one-way drive mechanism 94. That is, the payout stack motor 81 is commonly used as a drive source for the reject stack plate 45 and the guide plate 44, and one of the two is driven in accordance with the rotation direction.

The vertical position of the reject stack plate 45 is as follows.
The reject stack plate 45 is constantly monitored by the upper limit sensor 52 and the lower limit sensor 53 (see FIG. 3), and the operation / stop of the payout stack motor 81 is controlled in accordance with the outputs of these sensors 52 and 53. , Between the standby position shown in FIG. 1 and the reject position shown in FIG. Reference numeral 54 in FIG. 3 denotes a second switch that detects whether or not the banknote A is held in the reject holding unit 42.

Next, the operation of the reject device 17 having the above configuration will be described with reference to FIGS. In the standby state shown in FIG. 1, the crank pin 92a of the pulley gear 92 is located at the bottom dead center and is in contact with the step portion 91 of the cam groove 91, and the first and second link levers 86a and 86b are in the contracted state. As a result, the reject stack plate 45 is located at the upper standby position. In this state, the bill A is sent from the payout conveyance path 13 to the collective holding unit 41.

When the state in which the bills A are overlapped and sent is detected, the payout stack motor 81 is rotated forward by a predetermined angle after the guide plate 44 is raised, so that the one-way drive mechanism 94 and the intermediate gear 93 are rotated. , The pulley gear 92 is rotated counterclockwise (in the direction of arrow B) to the angular position in FIG. 2 where the crank pin 92a is located slightly before the top dead center. Accordingly, the second link lever 86
b is pushed up by the crank pin 92a via the upper edge 91a of the cam groove 91, and the torsion coil spring 87
, The first and second link levers extend downward, and the reject stack plate 45 descends to the lower reject position, and the banknote A
Is passed through the guide plates 44, 44, sent from the batch holding unit 41 to the reject holding unit 42, and held.

Thereafter, when the payout stack motor 81 rotates forward by a predetermined angle again, the pulley gear 92 rotates in the same direction as described above, and the crank pin 92a moves beyond the top dead center toward the bottom dead center. When the top dead center is exceeded, the crankpin 9
2 is pushed downward by the spring force of the torsion coil spring 87 via the upper edge 91a of the cam groove 91 of the second link lever 86b. On the other hand, since the pulley gear 92 is freely rotatable in this direction, the crank pin 92a comes into contact with the lower edge 91b of the cam groove 91, whereby the pulley gear 92 is braked.

Then, at the next timing, the upper edge 91a of the cam groove 91 comes into contact with the crank pin 92a again and presses the same by the spring force of the torsion coil spring 87. The pulley gear 92 is braked by again contacting the lower edge 91b. As described above, when the pulley gear 92 returns to the bottom dead center, the crank pin 92a is repeatedly braked by the lower edge 91b of the cam groove 91, so that the pulley gear 92 does not overshoot the bottom dead center significantly, and Stop reliably near the point. Therefore, the reject stack plate 45
Can be reliably stopped near the standby position, and as a result, the banknotes A can be smoothly accumulated in the batch holding unit 41 without causing jamming or the like.

Further, as described above, the lower edge 9 of the cam groove 91 is formed.
Since the pulley gear 92 is stopped at the bottom dead center by the braking by 1b, even if the dimensional relationship or the mechanical load changes due to, for example, abrasion of the cam groove 91 or the crank pin 92a as the device is used, it is affected by the change. Without this, the reject stack plate 45 can be stably stopped near the standby position. Further, the reject device 17 is different from the conventional one in that the existing link lever 8 is used.
A simple configuration can be achieved simply by forming the cam groove 91 in the 6b.

In the embodiment described above, the cam grooves 91
Has a shape in which the tip side is open, but may have a closed slot shape. Although the embodiment is an example in which the present invention is applied to a recycle building validator, it is needless to say that the present invention can be applied to other types of banknote collective payout apparatuses.

[0047]

As described above, the rejecting device of the banknote batch dispensing device of the present invention has a simple structure, and has an effect that the reject stack plate can be reliably and stably stopped at the standby position. ing.

[Claims] 1. A motor, a rotating body having an eccentric crankpin, and a rotating body provided between the motor and the rotating body, for rotating the rotating body when the motor rotates normally, and for rotating the rotating body in reverse. A one-way drive mechanism that locks the rotation in one direction, and a one-way drive mechanism that is rotatably connected to each other at a central connection part, and one of which is engaged with the crank pin of the rotating body with play at a position above the connection part. And a pair of pantograph-shaped link levers that expand and contract in the vertical direction by being driven by the rotation of the rotating body through the cam grooves. Attached movably, along with the expansion and contraction of the pair of link levers, an upper standby position to allow acceptance of bills downward,
A reject stack plate that can be moved up and down between a lower reject position for rejecting a received bill downward, and a spring that biases the pair of link levers to the standby position side. Characteristic rejection device for banknote batch dispensing device.
