Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention is directed to a mechanism for transferring coins in a coin processing module 10 having a validator 22, an escrow 24, a hopper 26, a cassette 28, and the like. A charging port 11 is disposed above the coin processing module 10 and a discharge port 12 and a coin box 15 are disposed below. The validator 22 classifies the coins by size to increase the accuracy of coin recognition. The validator 22 is configured to exclude mechanical moving parts to minimize wear and avoid coin jamming. The valid coins are conveyed by the validator 22 to the escrow 24, which is a temporary storage unit. The escrow 24 is located below the validator 22 and moves the coin to the hopper 26 after the normal ticket release is completed. The hopper 26 stores coins inserted by the user and discharges money to the user. The cassette 28 has a separate backup hopper inside, and functions to discharge a deficient amount of money from the hopper 26 to the user.

According to the present invention, the hopper 26 of the coin processing module 10 and the chain conveyor 30 are installed in the downward direction of the cassette 28. The coin handling module 10 can be detached from the main body frame by attaching a guide rail, thereby facilitating maintenance. At the same time, when the device is replaced with a plug-in connector, it can be easily removed from the ticket dispenser, and movement of the guide rail can be recognized by attaching a detachment switch. The chain conveyor 30 is disposed in the lower space of the coin processing module 10 and is detachable together with the coin processing module 10. Guide tongues 36 are formed on the covers 35 on both sides for tight support of the chain conveyor 30 and smooth traveling movement. The cover 35 on both sides maintains a certain clearance through the guide pin 38. [ The length of the chain conveyor 30 to extend across both the hopper 26 and the cassette 28 is increased while the length of the chain conveyor 30 can be reduced by adding the coin guiding passage to the upper side.

At this time, the chain 31 of the chain conveyor 30 is provided with an upper jaw 32 for preventing a coin from slipping on the upper surface and a front jaw 33 for preventing a coin from being caught on the entire surface. The material of the chain 31 constituting the chain conveyor 30 can be injection-molded using a resin material having wear resistance. The chain 31 includes an engagement portion 31c for engaging with a driven gear 48 to be described later in addition to a shaft portion 31a and a groove portion 31b for mutual connection and a stop jaw 31d An upper jaw 32 formed on the upper surface, a front jaw 33 formed on the front surface, and the like. The upper jaw 32 prevents slippage so that the coin falling from the upper portion does not protrude in any direction. The front jaws 33 prevent coins from being caught between the adjacent chains 31. When such a chain conveyor 30 is used, it is easy to change the length depending on the type of the coin processing module 10, so that the flexibility of production is improved.

According to the present invention, the drive means 40 is provided to move the chain conveyor 30 forward or backward. The driving means 40 moves the chain conveyor 30 in the forward direction to send the coin to the discharge port 12 or to move the chain conveyor 30 in the reverse direction to send the coin to the coin box 15. The discharge port 12 is a passage for giving money to the user, and the coin box 15 is a container for collecting the defective coin or collecting all the coins of the hopper 26.

The driving means 40 transmits the driving force of the motor 42 to the belt 44 provided between the driving gear 46 and the driven gear 48. In this case, It is preferable that the motor 42 uses a stepping motor in terms of simplicity of control. The driven gear 48 is in the form of a sprocket which engages with the chain conveyor 30. The transfer of the driving force of the motor 42 to the chain conveyor 30 by the belt 44 is advantageous for preventing breakage due to overload in the situation of coin closure.

In addition, according to the present invention, the controller 50 includes a variable controller that determines the output of the driving unit 40 in accordance with an established algorithm. The controller 50 includes a memory and a main board 52 of a microcomputer circuit having an input / output interface, and transmits / receives control information to / from a VM (Vending Machine) through wired / wireless communication. A VM, a sensor, and the like are connected to the input interface of the main board 52, and the hopper 26, the cassette 28, the driving means 40, and the like are connected to the output interface. Accordingly, each accessory device in the coin processing module 10 is controlled by the control of the VM's kettle control device (VM ECU), and all the accounting and statistical data generated in the coin processing process is transmitted to the VM's kettle control device do.

At this time, the controller 50 inputs a signal of the sensor using the main board 52 and generates an output to the driving means 40. [ The controller 50 receives the coins discharged from the escrow 24, the hopper 26 and the cassette 28 and transfers the coins to the discharge port 12 or the coin box 15.

According to the detailed configuration of the present invention, the controller 50 includes a sensor for inputting a signal of a sensor using the main board 52, generating an output to the driving means 40, and recognizing an abnormal interrupt situation, (54). That is, the abnormal interrupt situation is detected through various sensors, and information on such situation is displayed on the display 54. [

At this time, the controller 50 drives the chain conveyor 30 in the reverse direction to send out the coin box 15 when the coin on the chain conveyor 30 is inconsistent with the amount of the coin or the coin is arbitrarily mass-dropped. In the case of the former case, when the amount of the replacement money sent out from the hopper 26 and the cassette 28 is inconsistent, the chain conveyor 30 repeats the settlement using the same function as the second escrow 24. In the latter case, it is prevented from being paid to the user arbitrarily when a jackpot error occurs in which a coin is sent out in a stack due to abnormality of the hopper 26 or the cassette 28. [

6, the distance between the inlet 11 and the outlet 12 is increased due to the free fall method using the ramp 18. In contrast, according to the present invention, the height of the outlet 12 can be kept high, (11).

Meanwhile, since the coin processing module 10 of the present invention has a modular structure as a whole, it is easy to attach and detach, thereby providing convenience in maintenance.

Particularly, even in the case of the chain conveyor 30 and the cover 35, a structure in which they are integrally modularized and are removable is adopted.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention as defined by the appended claims. It is therefore intended that such variations and modifications fall within the scope of the appended claims.
