Description

[Detailed Description of the Invention] The present invention relates to a coin constant feeding device for constantly feeding coins such as coins or game coins.

For example, when taking out a fixed number of coins from a money changer, etc., you can open the gate and close the gate when the number of coins passing through reaches a fixed number, but if the gate opening/closing time is even slightly longer,
The coins exceeding the fixed number will come out, and on the other hand, if the number is even slightly shorter, the fixed number will not be met, so even the slightest deviation in detection and opening/closing timing cannot be tolerated.

Additionally, there is a device that opens and closes the gate by detecting passing coins with a light-receiving element and counting them with a counter, etc., but this device is prone to malfunction due to dirt getting into the light-receiving surface or the path of the light beam, so it is not reliable. In addition, there were disadvantages such as a DC power supply circuit, a counting circuit, etc. being required, and the electric circuit becoming complicated.

The present invention was developed in view of the above circumstances, and its purpose is to rotate the rotary disk by pressing a pin protruding from the rotary disk with a coin passing through the coin passage, and to cause the coin to be coined by the rotational displacement of the rotary disk. The present invention aims to provide a constant coin dispensing device which solves the above problem by controlling the dispensing mechanism.

The present invention will be explained below with reference to embodiments shown in the drawings.

A coin passage 2 is formed in the lower part of the frame 1 along the horizontal direction, and a coin drop opening 3 is provided in communication with the terminal end of the coin passage 2. is provided with a coin feeding mechanism, for example, a coin feeding disk (not shown), and the coins C sequentially fed by this disk (not shown) are brought into contact with each other in the coin passage 2 with their outer circumferential surfaces touching each other, and the coins fall into the coin drop slot. It is designed to roll forward to the third side.

A rotary disk 4 is disposed above the terminal end of the coin passage 2,
A central portion of the rotary disk 4 is rotatably supported on the frame 1 by a shaft 5 in the direction of arrow a, and a lower portion of the rotary disk 4 protrudes into the coin passage 2.

A large number of pins 6 are annularly protruded from the peripheral edge of one side of the rotary disk 4 at regular intervals slightly smaller than the diameter of the coin C, concentrically with the outer peripheral edge of the rotary disk 4, and each of these pins 6
is pressed by the coin C rolling forward in the coin passage 2, so that the rotary disk 4 rotates in the direction of arrow a.

One reset pin 7 is provided at the eccentric position of the rotary disk 4.
is installed protrudingly.

An elongated hole 9 formed in one side of the control lever 8 disposed on the upper part of the frame 1 engages with a pin 10 protruding from the frame 1. A tension spring 13 is interposed between a pin 11 protruding from one end and a pin 12 protruding from the top of the frame 1, and the elastic force of the spring 13 causes the control lever 8 to move around the pin 10 as a fulcrum. It is biased in a clockwise direction.

Further, a limit switch 14 disposed above the control lever 8 is fixed to the frame 1, an operating piece 14a of this switch 14 is disposed above the lever 8, and the limit switch 14 is used for feeding out the coins. By connecting to the power supply of the drive motor (not shown) for the disc (not shown),
When the pressure on the operating piece 14a of the limit switch 14 is released, an electric contact (not shown) of the limit switch 14 is turned on and a coin feeding disk (not shown) is driven.

Then, the control lever 8 is pushed up and rotated by the reset pin 7, and when the lever 8 is in a substantially horizontal state as shown by the solid line in FIG. An electric contact (not shown) is turned off to stop driving a coin dispensing disk (not shown).

Reference numeral 15 denotes a solenoid fixed to the upper part of the frame 1, and a pushing rod 16 fixed to a piston 15a of the solenoid 15 is placed opposite and close to the other side of the control lever 8 in a horizontal state.

When an input signal is transmitted to the solenoid 15 by inserting a bill or coin, the solenoid 15 is energized and the push rod 16 moves in the direction of arrow A to press the control lever 8.
When the lever 8 moves in the direction of arrow A, the lock between the control lever 8 and the reset pin 7 is released, and the control lever 8 rotates clockwise to the state shown by the two-dot chain line in FIG. The rotary disk 4 is released from the pressure of the control lever 8 and becomes free, and at the same time, the pressure on the operating piece 14a of the limit switch 14 is released and the switch 14 is turned on. .

In the figure, 17 is the earthen wall of the coin passage 2, and 18 is the push rod 16.
This is a spring interposed between the frame body 1 and the frame body 1.

To explain the operation of the device configured as above,
In a normal state, as shown by the solid line in FIG. Therefore, this switch 14 is turned off, and the coin feeding disk (not shown) stops.
Each coin C in the coin passage 2 is also stopped.

When a banknote or coin is inserted, an input signal is transmitted to the solenoid 15, and when this solenoid 15 is energized, the push rod 16 presses the control lever 8, so the control lever 8 moves and resets the reset pin. 7 and these locks are released, the control lever 8 rotates clockwise around the pin 10 due to the elastic force of the tension spring 13 and reaches the position indicated by the two-dot chain line in FIG. at the same time,
The pressure on the operating piece 14a of the limit switch 14 is released, and the limit switch 14 is turned on.

Then, the coin feeding disk (not shown) rotates and presses the coins C into the coin passage 2 one after another and sends them out. Each pin 6 is pressed by the coin C, and the rotary disk 4 rotates in the direction of arrow a.

When the coin dispensing disk (not shown) rotates, the coins C are sequentially fed out, and after rotating the rotary disk 4 one pitch at a time in the direction of arrow a, each coin C is sent out one by one.
The coins fall one by one from the coin drop port 3.

Eventually, when the reset pin 7 protruding from the rotary disk 4 reaches the position indicated by the two-dot chain line in FIG. 1, it comes into contact with the control lever 8.
Push this up.

When the pushed-up control lever 8 reaches a substantially horizontal state, this lever 8 engages the operating piece 14a of the limit switch 14.
When the control lever 8 presses the operating piece 14a of the limit switch 14, the limit switch 14 is turned off and the coin feeding disk (not shown) stops.
Each coin C also stops moving.

In this way, the coin C passing through the coin passage 2 presses the pin 6 to rotate the rotary disk 4 in the direction of the arrow a, and the rotary disk 4 rotates by a predetermined angle (one rotation in this embodiment) in the direction of the arrow a. Then, the limit switch 14 is operated to stop the rotation of the coin feeding disk (not shown), so that the coin C can be reliably fed at a constant rate.

Note that if the number of coins C to be sent out is changed, it is only necessary to replace it with a corresponding rotary disk or change the number of reset pins 7 (one in this example), or if the type of coins is different. In that case, you can replace it with a corresponding rotary disk.

As is clear from the above description, the present invention rotates a rotary disk with each coin passing through the coin passage, and when the rotary disk rotates a predetermined angle, the rotary disk activates the switch mechanism of the coin feeding mechanism via the control lever. Since the switch mechanism is turned OFF and turned ON via the push rod in response to an input signal, it is possible to reliably send out a predetermined number of each coin.

In addition, the structure is simple, and there is no need for electrical circuits such as light receiving elements, counting circuits, and DC power supply circuits that are prone to failure, so there is little room for failure, and stable operation can be achieved over a long period of time. It also has excellent practical effects, such as being able to be manufactured at low cost.
