Description

The present invention relates to a coin dispensing device used in a coin processing device such as a vending machine.

(B) Conventional technology A coin dispensing device of this type has hitherto been disclosed, for example, in Japanese Utility Model Laid-Open No. 54-7049.
As shown in Japanese Patent Publication No. 9, a plurality of coin storage cylinders in which coins are stacked and stored in the thickness direction are provided, a coin storage cylinder from which coins should be dispensed is selected by the operation of a solenoid, and a common drive is provided for each coin storage cylinder. The coin is paid out by the rotation of the motor.

(C) Problems to be Solved by the Invention This type of coin dispensing device is premised on a coin dispensing device in a coin processing device in which a plurality of coin storage cylinders are arranged in a row in the lateral direction. However, as a coin processing device used in a vending machine, it is preferable that as many coin storage cylinders as possible can be installed in order to prevent a shortage of change or to cope with an increase in change coin denominations. For this reason, it is conceivable to increase the number of coin storage cylinders arranged in a row, but in that case, the front width dimension of the coin processing device becomes large, and the vending machine for mounting it must be made large. , There is a problem that compatibility with existing vending machines is lost. Therefore, it is conceivable to add a coin storage cylinder to the space behind the coin storage cylinders arranged in a horizontal row on the front surface. In this case, however, the coins of the added coin storage cylinder are dispensed in the above-described conventional technique. Therefore, it is necessary to install a drive motor for each additional coin storage cylinder to dispense coins, but there is a problem in that it is difficult in terms of space to increase the number of drive motors.

The present invention provides a coin payout device that can pay out coins of a plurality of coin storage cylinders that are individually installed by a common drive motor.

(D) Means for Solving the Problems The present invention provides a plurality of coin storage cylinders in which coins are stacked and stored in the thickness direction, selects a coin storage cylinder from which coins should be dispensed by the operation of a solenoid, and then each coin In a coin dispensing device adapted to dispense coins by rotating a drive motor commonly used in a storage cylinder, an extrusion unit is provided at an upper portion for protruding the lowest coin by protruding onto a bottom wall in the coin storage cylinder. A connecting member that is urged downward by a spring member so as to be retractable, and a repatriating member that is reciprocally movable in the coin payout direction; and a reciprocating movement in the same direction as the payout member by the drive motor. And a drive member which is provided with a connection groove in which the connection member can be freely fitted and an escape groove which opens a part of the connection groove at one end, and which is connected to the payout member when the connection member engages with the connection groove,
In the standby state, the operating rod protruding through the relief groove pushes up the connecting member to prevent the connecting member from engaging with the connecting groove, and the excitation by the payout command releases the pushing up by the operating rod to release the connecting member and the connecting groove. And a solenoid for engaging the above.

(E) Action In the standby state, the solenoid is in a non-excited state and the operating rod pushes up the connecting member to release the connection between the payout member and the driving member. In this state, when the drive motor is rotated to dispense coins from the other coin storage cylinder, only the drive member reciprocates. At this time, the operating rod does not hinder the reciprocating movement of the driving member because it is in the clearance groove of the driving member.
Further, when the solenoid is excited by the coin payout command, the operating rod stops the pushing and urging force of the connecting member, so that the connecting member projects downward by the spring member and engages with the connecting groove of the driving member. By this engagement, the payout member and the drive member are connected, and the drive member and the payout member both reciprocate by the rotation of the drive motor, and the pushing-out portion of the payout member pays out the lowest coin in the coin storage cylinder.

(F) Embodiments Each drawing shows a coin dispensing device according to an embodiment of the present invention.

The coin dispensing device (1) is installed in a coin processing device (not shown), and is installed behind a plurality of coin storage cylinders (not shown) arranged in a line in a horizontal direction. The coins of the coin storage cylinders (3) and (3) provided on both sides are dispensed from the dispense port (4) by the rotation of the drive motor (2).

In the base (1A) of the coin dispensing device (1), a disc (5) which is rotated by the rotation of the drive motor (2) is provided in a substantially horizontal state. A drive rod (5A) that protrudes in is provided. And this drive rod (5A)
Is loosely fitted in the drive groove (6A) of the drive member (6), and one rotation of the disc (5) causes the drive member (6) to move in the direction of arrow (C) shown in FIG. It is designed to move back and forth.

As shown in FIG. 1, the drive member (6) is provided with a drive groove (6A) on the left end side of the lower surface and a connecting member (9) provided on the payout member (8) described later on the right end side of the upper surface. A possible connecting groove (6B) is provided, and the drive member (6) moves in the direction of arrow (C) with the operating rod (13) of the solenoid (12) described later interposed in this connecting groove (6B). As you like
There is a relief groove (6C) that opens to the right end. As shown in FIGS. 2 and 3, the drive member (6) is guided by the guide grooves (7) provided on the base body (1A) at both front and rear ends to the first position.
It is reciprocally movable in the direction of the arrow (C) in the figure.

The payout member (8) has an extruding part (8A) on the upper surface, which projects on the bottom wall (3A) in the coin storage cylinder (3) and extrudes the lowest coin (D) from the opening (3B), and on the lower surface. A connecting member (9), which is urged downward by a spring member (10), is internally provided so as to be retractable. The connecting member (9) is located on the connecting groove (6B) of the driving member (6) when the payout member (8) and the driving member (6) are in a standby state as shown in FIG. And can be engaged in this connecting groove (6B),
At the time of engagement, the payout member (8) and the drive member (6) are connected. Further, the lower surface of the payout member (8) is located at a position corresponding to the right side of the connecting member (9) and protrudes downward substantially to the same extent as the downward projecting size of the connecting member (9) and is inclined to the upper right. A piece (8B) is provided, and as shown in FIG. 6, when the payout member (8) is returned to the standby state, the operating rod (13) of the solenoid (12), which will be described later, is moved downward along the inclination. However, the engagement between the operating rod (13) and the connecting member (9) is guided. Further, as shown in FIG. 3, the guide piece (8B) projects into the guide groove (6C) of the drive member (6) corresponding to the operating rod (13).
Further, at the right end of the payout member (8), as shown in FIGS. 1 and 3, a contact piece that comes into contact with the right end of the drive member (6) when returning the payout member (8) to the standby position. (8C) is provided. Further, as shown in FIGS. 2 and 3, the payout member (8) has guide grooves (11) having front and rear ends provided on the base body (1A).
Is provided so as to be reciprocally movable in the direction of the arrow (C) in FIG.

The solenoid (12) is provided with an actuating rod (13) that is moved downward by an excitation based on a coin payout command, and the actuating rod (13) extends from a hole (14) opened in the base body (1A) to the connecting member. The spring member (15) having a stronger elasticity than the spring member (10) for biasing (9) to project is biased upward to project. The operating rod (13) faces the connecting member (9) when the payout member (8) is in the standby position, and pushes the connecting member (9) upward against the elasticity of the spring member (10). However, the engagement between the connecting member (9) and the connecting groove (6B) is prevented. Further, since the operating rod (13) projects through the escape groove (6C) of the driving member (6) into the connecting groove (6B) to control the connecting member (9), the reciprocating movement of the driving member (6) is prevented. It does not interfere.

The coin storage cylinder (3) is, as shown in FIGS. 1 and 3,
A bottom wall (3A) that can store coins (D) stacked in the thickness direction is provided in the lower part, and the bottom wall (3A) has a push-out portion (8A) of the dispensing member (8) at an arrow ( A push-out passage (3C) which is reciprocally movable in the direction C) is provided with an opening, and an opening (3B) which is a delivery port for the coin (D) pushed out by the pushing section (8A) is provided. The coin storage cylinder (3) is detachably mounted by locking the locking pieces (16) provided on the front and rear surfaces into the locking holes (1B) formed on the front and rear surfaces of the base body (1A). . (17) is a coin payout passage for guiding and sending out the coin (D) pushed out from the opening (3B) to the payout opening (4).

Next, the operation of the above configuration will be described. The standby state is shown in FIGS. That is, the drive member (6) and the payout member (8) are located at the right ends of the guide grooves (7) and (11), respectively, and the pushing portion (8A) is located outside the coin storage cylinder (3). Also, since the solenoid (12) is demagnetized,
The operating rod (13) pushes the connecting member (9) upward through the escape groove (6C), and the connecting member (9) is connected to the connecting groove (6B).
The drive member (6) and the payout member (8) are disconnected from each other by being located above.

When a coin payout command is delivered here, the solenoid (12) is excited and the operating rod (13) is moved downward by suction as shown in FIG. 4, so that the connecting member (9) moves to the spring member (10). ) Of the driving member (6), and the connecting groove (6
B) is loosely fitted and engaged to drive member (6) and payout member (8)
To connect. Then, when the disk (5) is rotated by the rotation of the drive motor (2), the drive member (6) is driven by the drive groove (6A).
By the drive rod (5A) loosely engaged with, the coin is moved together with the payout member (8) in the direction of the arrow (C) shown in FIG. At the time of this reciprocation, the lowest coin (D) on the bottom wall (3A) in the coin storage cylinder (3) is pressed by the pushing portion (8A) of the payout member (8) to open as shown in FIG. Coin payout passage from (3B) (17)
Be paid to.

Then, when the disc (5) further rotates and the drive member (6) and the payout member (8) return, and reaches the operating rod (13) which is projected and restored by demagnetization of the solenoid (12), As shown in FIG. 6, the guide piece (8B) of the payout member (8) abuts the upper end of the operating rod (13) and its inclination causes the operating rod (13) to move.
Is moved downward, and the upper end of the operating rod (13) is brought into contact with the lower surface of the connecting member (9) protruding downward. Therefore, the connecting member (9) is pressed upward by the operating rod (13) to release the engagement with the connecting groove (6B). Thereby, the payout member (8)
Releases the connection with the drive member (6), but the contact piece (8C)
Is abuttingly locked to the drive member (6), the drive member (6) causes the drive member (6) to return to the standby position. When the drive member (6) returns to the standby position, a position detection device (not shown) operates and the drive motor (2) stops.

Next, a case where the drive motor (2) is rotated for paying out coins in the other coin storage cylinder (3) will be described. In this case, since the solenoid (12) is not excited and remains in the demagnetized state, the connecting member (9) is pushed up by the operating rod (13), and therefore the payout member (8) and the drive member ( Not linked to 6). Therefore, the drive member (6) independently reciprocates and returns as shown in FIG. 7 by the rotation of the disc (5). Therefore, the coin (D) in the coin storage cylinder (3) shown in FIG. 7 is not dispensed.

(G) Effect of the Invention Since the present invention is configured as described above, even if coins of a plurality of coin storage cylinders that are individually set apart are paid out by a common drive motor, the payout can be made. The coin storage cylinder to be dispensed can be easily selected, and the coin can be dispensed reliably. Therefore, it is possible to increase the number of coin storage cylinders without increasing the size of the coin processing device and to produce a compatible coin processing device.
