Description

Hopper device for vending machine.

The present invention relates to a hopper device for a vending machine. More specifically, the present invention relates to a hopper device for a vending machine capable of discharging various gift certificates or tickets, cards, lotteries, and the like one by one.

Typically, the vending machine is equipped with a hopper device that can discharge a predetermined amount by a user's button operation. Among such vending machines, conventionally designed products which are standardized in a certain shape, for example, various types of gift certificates, tickets, public telephone cards, subway passes (hereinafter collectively referred to as gift certificates) made of paper, plastic or metal, etc. are sequentially discharged. A hopper device for a vending machine is shown in FIG.

As illustrated, the hopper device 100 'for a conventional vending machine is provided with an accommodating portion 10' in which a plurality of gift certificates 2 'are stacked and accommodated, and at one side of the accommodating portion 10'. A solenoid portion 20 'is provided for discharging a predetermined gift certificate from the storage portion 10' to the outside.

The solenoid portion 20 'is provided with a bar 22' so as to be moved forward and backward by an electrical operation. When the solenoid portion 20 'is not operated, the bar 22' is retracted and fixed. A spring 24 'is fixed to one side of the bar 22', and the other end of the spring 24 'is fixed to one end of the base 30' on which the hopper device 100 'is located.

In addition, a through hole 12 ′ is formed at a lower end of the storage portion 10 ′ so that the bar 22 ′ penetrates and pushes the lowest gift certificate 2 ′ to the outside. A discharge hole 14 'is formed at the side of 12').

In addition, the upper end of the upper portion of the gift certificate (2 ') of the upper portion of the gift certificate (2'), the pressing 16 'having a constant weight is positioned to be able to press the gift certificate to the bottom. Here, the circumference of the presser 16 'is all chamfered or rounded so that when the gift certificate 2' is all discharged and the bar 22 'of the solenoid portion 20' is in direct contact with the bar 22 '. Is not damaged.

In the conventional vending machine hopper device 100 ′, power is applied to the solenoid unit 20 ′ when the user first inserts a certain amount of coins and designates a desired button. Then, the bar 22 ′ of the solenoid portion 20 ′ is inserted into the through hole 12 ′ formed on the bottom of the receiving portion 10 ′ by overcoming the elastic force of the spring 24 ′ and advancing forward. Then, the gift certificate (2 ') located at the lower end of the accommodating portion (10') is pushed to the end of the bar 22 'is discharged to the outside along the discharge hole (14').

However, the conventional hopper device for a vending machine has no problem when the vouchers stored in the storage unit are relatively thick, but when the very thin vouchers are stored, the vouchers are not correctly discharged one by one.

In other words, when the gift certificate is very thin, all the gift certificates are stacked in a direction substantially perpendicular to the ground, so that when the bar is inserted into the through hole of the receiving part, a plurality of gift certificates are pushed simultaneously or the gift certificates are jammed in the storing part. Occurs frequently.

In addition, since the operation of discharging the gift certificate is made by the sudden forward and backward operations of the bar, the gift certificate is suddenly discharged instead of being discharged smoothly, and thus there is a problem that the merchandise of the hopper device is greatly reduced.

In addition, the solenoid has a problem that the noise is too high during operation of the hopper device adopting the solenoid by moving the bar forward and backward by electrical operation, thus causing a user's discomfort during use of the hopper device.

The present invention has been made to solve the conventional problems as described above, to provide a hopper device for a vending machine that can accurately discharge a variety of gift certificates or tickets.
