Abstract

PURPOSE:To prevent a foreign body such as a clip and a setting pin from passing through a coin separation part of the coin reception and payment device by automatically rejecting the foreign body at the coin separation part. CONSTITUTION:A coin restriction guide 17 of the coin separation part has a gap a little larger than one coin with the top surface of a rotary disk 15 and separates coins, one by one. The rotary disk 15 can rotate forward and backward, and rotates slower backward than forward. An electromagnet 25 is fitted to the upper part of the coin restriction guide 17 and is powered during coin separation to attract the foreign body 26 such as the clip and setting pin. At the time of the coin separation, the coins advance along the peripheral edge of the separation part with the centrifugal force of the rotary disk 15 which rotates forward and are carried through the guide 17. After the coin separation, the electromagnet 25 is released from being powered, so the foreign body 26 falls on the rotary disk 15, which reverses slower; and a rejection shutter 22 is opened, so the foreign body 26 is rejected to a rejection conveyance path 23.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coin depositing / dispensing device for removing foreign matter when separating coins one by one by centrifugal force and feeding them out to a coin transport path.

[0002]

2. Description of the Related Art A conventional coin depositing / dispensing device is a real coin shovel 61-4.
As described in Japanese Patent No. 6673, when a coin is caught between a rotating disc of a coin separating section and a coin regulating guide, and a decrease in the rotation speed of the rotating disc is detected, the thickness regulating member is raised and the rotating disc is rotated in reverse. The jam was cleared.

[0003]

The above-mentioned prior art relates to a method for removing the bite of coins, but the removal of foreign matter is not taken into consideration, and the foreign matter is taken into the apparatus when coins are separated again. There is a problem that it becomes a cause of trouble of the device. The present invention solves the above problems, capturing foreign matter such as clips and insect pins during coin separation,
The object is to reduce the idle rate of the device by removing the foreign matter into the reject conveyance path and preventing foreign matters from passing through the coin separating section.

[0004]

In order to achieve the above-mentioned object, the present invention provides a coin separating section, a mechanism for rotating a rotating disk of the coin separating section forward and backward, and a reject conveying path.
A shutter mechanism that opens and closes the reject transport path and an electromagnet above the coin regulation guide are installed to energize the electromagnet during coin separation to adsorb foreign matter such as clips and insect pins, and after decoupling, stop energizing the electromagnet and rotate the foreign matter. It is dropped onto a disc and the shirt of the reject transport path is opened to slowly reverse the rotating disc to remove foreign matter to the reject transport path.

[0005]

With the above means, foreign matters such as clips and insect pins are attracted to the electromagnet during coin separation, so that only coins are fed to the coin transport path, and foreign matters such as clips and insect pins are not fed. After the coin separation is completed, the energization of the electromagnet is stopped, so that the foreign matter falls on the rotating disk, the shirt of the reject transport path is opened, and the rotary disk is slowly reversed, so that the foreign matter is removed to the reject transport path. As a result, foreign matter can be prevented from slipping through the coin separating portion.

FIG. 1 shows a schematic configuration of a coin depositing / dispensing device. The deposit coins inserted into the deposit / withdrawal port 2 of the coin depositing / dispensing device 1 by the customer are separated one by one by the deposit coin separating unit 3 and conveyed to the first discriminating unit 4. The first discriminating unit 4 discriminates the authenticity of coins and the denomination, and the data thereof is used by the control unit 12
Send to. The deposited coin separating unit 3 includes a detection unit that detects the remaining coins and the passage of coins in the coin transport path. The control unit 12 stacks the true coins on the temporary stack 5 according to the received data. The fake coin is conveyed to the payment belt 9 through a reject passage (not shown). When the coins that have been temporarily stacked are stored according to the customer's instructions, they are separated by the stored coin separating unit 6 and are conveyed to the second discriminating unit 7.
The second discrimination unit 7 discriminates the denomination and sends the data to the control unit 12. The control unit 12 stores the data in the storage cylinder 8 for each denomination according to the received data. The coins returned by the customer's designation are conveyed to the payment belt 9. The coins stored in the storage cylinder 8 are thrown out one by one to the payment belt 9 in accordance with a withdrawal instruction from the control unit 12. The withdrawal coins thrown out to the payment belt 9, or the rejected coins and the returned coins that have been conveyed are removed by the payment belt 9 from the withdrawal coin separation unit
Can be lifted to zero. The lifted coins are separated one by one by the coin dispenser separating unit 10 and conveyed to the deposit / withdrawal port 2 by the reverse dispensing belt 11.

2 and 3 show a schematic mechanism of a depositing coin separating portion to which an embodiment of the present invention is applied. FIG. 2 is a top view, and FIG. 3 is a side surface for showing a mounting position of an electromagnet. It is a figure. The coins inserted into the deposit / withdrawal port are the deposit coin separating unit 3
Sent to. Coins 14 in the deposited coin separator 3
Moves along the peripheral wall plate at the peripheral edge of the rotating disk due to the centrifugal force of the rotation of the rotating disk 15 in the A direction. A coin regulation guide 17 having a width slightly larger than the diameter of the coin is provided on the upper surface of the rotating disc 15, and the upper surface of the rotating disc 15 and the coin regulation guide 17 are provided.
A gap slightly larger than the thickness of one coin is provided between
It prevents two or more coins from overlapping and entering the transport path. The coin that has advanced along the prevention peripheral wall plate passes through the coin regulation guide 17 and enters the coin transport path 19 along the coin guide 18. As shown in FIG. 3, an electromagnet 25 is provided above the coin regulation guide 17, and when the electromagnet 25 is energized, the electromagnet 25 adsorbs foreign matter such as clips and insect pins. The disc drive motor 24 of the rotary disc 15 is a step motor, and the control unit 12 controls the reverse rotation (B direction) to rotate slowly for the normal rotation (A direction) rotation speed. . The reject shutter 22 is an operating shaft 21 of the rotary solenoid 20.
