Abstract

PURPOSE:To increase the degree of freedom for the design of a door front by providing a belt conveyer driven by a motor in the middle way of a coin passage connecting an aperture at the machine side of a coin throw-in port to a coin mech. CONSTITUTION:The belt conveyer 6 is arranged almost horizontally between the exit of a coin shoot 5 and the reception port 2a of the coin mech 2, and it is provided with a belt 61 on which lugs 61a are provided protrusively at appropriate intervals. A coin 10 thrown in the coin throw-in port 4a is transported from the aperture 4b to the coin shoot 5, which turns a detecting lever 81 in a direction of arrow B in the middle stage sliding on the shoot 5, and after that, it is sent on the belt 61. The detecting lever 81 turns on a detection switch 8 in a short period. Thereby, the motor 7 is operated for a prescribed time, which travels the belt 61. The coin 10, after being carried on the belt 61, drops in the reception port 2a, then, is sent to the coin mech 2.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a coin receiving device for guiding a coin inserted into a coin slot to a coin knock in a vending machine.

[Conventional technology]

As this type of coin accepting device, the one shown in FIG. 4 is often used. In the figure, a coin mech 2 having a receiving opening 2a on the top surface of the vending machine is disposed on the inside of a shallow box-shaped door 1 forming the front surface of the vending machine. In addition, the coin slot body 4 is fixed to the front panel 1a of the door 1 to open the coin slot 4a, and a coin chute 5 is provided to connect the inside opening 4b of the coin slot 4a to the receiving slot 2a of the coin mech 2. The coin accepting device 3 is configured. The coins inserted into the coin slot 4a fall onto the coin chute 5 from the opening 4b, slide down the coin chute 5, and are guided to the coin mech 2.

[Problem to be solved by the invention]

By the way, since the conventional coin receiving device 3 relies on the coin chute 5 to transport coins, the coin mech 2
It is necessary to provide the coin chute 5 below the coin slot 4a and at a certain distance below the coin slot 4 so that the coin chute 5 has an appropriate inclination. In recent years, it has been desired to eliminate restrictions on the arrangement of the coin mech in relation to the design of the front surface of the door 1.

SUMMARY OF THE INVENTION An object of the present invention is to provide a coin receiving device for a vending machine in which a coin knock can be placed in a coin slot without being restricted.

[Means to solve the problem]

In order to achieve the above object, the present invention provides a coin receiving device for guiding coins inserted into a coin slot opened on the front side of a vending machine to a coin mech disposed inside the machine. A belt conveyor driven by a motor is provided in the middle of a coin passage connecting the inside opening of the input slot and the coin knock.

[Effect]

Coins inserted into the coin slot are conveyed horizontally or upwards by a conveyor belt. Therefore, restrictions on the arrangement of the coin knock with respect to the coin slot can be eliminated.

〔Example〕

1 and 2 show an embodiment of the invention, and parts common or identical to those in FIG. 4 are designated by the same reference numerals.

In FIGS. 1 and 2, the coin mech 2 is placed a little farther back than the coin slot 4a, and not far below the coin slot 4a. A coin chute 5 having an appropriate slope and having a shorter length than the conventional one is installed facing the inside opening 4b of the coin slot 4a. 6 is the exit of the coin chute 5 and the receiving opening 2a of the coin mech 2.
A belt conveyor is disposed substantially horizontally between the belts 61 and 61, and has a belt 61 with protruding pawls 61a at appropriate intervals. 8
A detection switch is rotatably supported and activated by rotation of a detection lever 81 that projects above the coin chute 5, and is incorporated into the electric circuit of the motor 7.

In the above configuration, the coin 10 inserted into the coin slot 4a enters the coin chute 5 from the opening 4b, rotates the detection lever 81 in the direction of arrow B while sliding down the coin chute 5, and then passes through the belt 61. sent upwards.

When the coin IO passes, the detection lever 8 returns to its original state due to the bias of a spring (not shown), but the rotation turns on the detection switch 8 for a short period of time. As a result, the motor 7 is operated for a predetermined period of time to cause the belt 61 to travel. However, the coin lO that fell onto the belt 61 is
After being transported by, the coin falls into the receiving port 2a and is fed into the coin mech 2.

FIG. 4 shows another embodiment, in which the belt conveyor 6 has a belt 61 at the center of pulleys 62 at both ends.
A pulley 63 that guides the inside of the belt 61 and a pulley 64 that guides both left and right ends of the belt 61 are provided so that the belt 61 runs in an oval shape. In addition, a cover 9 is provided to cover the upper side and left and right sides of the belt 61.

In this embodiment, the coins 10 fed from the coin chute 5 onto the belt 61 are prevented from falling by the cover 9, are carried upwards on the belt 61, and are fed into the receiving opening 2a of the coin collector 2. Therefore Coin Mech 2
It is also possible to arrange the receiving opening 2a at approximately the same height as the coin insertion opening 4a or at a position higher than the coin insertion opening 4a.

〔Effect of the invention〕

According to the present invention, in a coin receiving device for guiding coins inserted into a coin slot opened at the front of a vending machine to a coin knock disposed inside the machine, an opening on the machine side of the coin slot and a A belt conveyor driven by a motor is provided in the middle of the coin path connecting the coin knock, so that coins inserted into the coin slot can be placed on the belt conveyor and transported horizontally or upward. , it is possible to eliminate restrictions on the arrangement of the coin slot of the coin mech. Therefore, the degree of freedom in designing the front surface of the door is extremely large, allowing for innovative designs.
