Description

Slot assembly for vending machines

The present invention relates to a slot assembly for a vending machine, and more particularly, an automatic automatic vending machine that guides the rotation of a spring for discharging the product, and guides the product mounted on the spring to facilitate discharging of the product. It relates to a slot assembly for a vending machine.

In general, vending machines temporarily store snacks such as ice cream or snacks, and when a user inserts coins or bills into the vending machine, discharges the stored products to the outlet.

More specifically, in order to discharge the product, the vending machine is provided with a plurality of slot assemblies. In the slot assembly, when a user presses an operation button of the vending machine, a motor provided inside the vending machine rotates once, and the motor The spiral-shaped spring coupled to the

At this time, as the spiral-shaped spring rotates once as described above, products loaded at each pitch linearly move by one pitch of the spring.

That is, by converting rotational motion into linear motion, products loaded between the spring intervals and pitches are moved one by one to the extreme end and freely fall down, so that they are discharged to the product outlet of the vending machine, for example, Vending machines such as Korean Utility Model No. 20-0224045 “Product Transfer Device for Vending Machine” and Korea Deungro Patent No. 10-1647043 “Vending Machine with Spiral Drive Applied” have been developed.

However, in the conventional spiral slot assembly configured as described above, the size of a product that can be sold is determined by the spacing between the springs, that is, the spacing between the pitches. In general, the spacing of the springs provided in a fixed manner is Since there is a limit to increasing the size, there is a problem in that the types and sizes of applicable products are limited.

In addition, in the case of a conventional vending machine, since the product is moved downward by one rotation of the spring and dropped downward, it is not expected that the product is dropped and sent to the outlet when the product is discharged. If the product is caught between the two or the spring or shaft of a conventional vending machine, there is a problem that the product cannot be discharged without the help of a technician.

In addition, in the case of a conventional vending machine, when the product is loaded, the area in which the product loaded on the line of the spring is supported is narrow, so the conveyance of the product is unstable.

Accordingly, it is possible to solve the problem that the product is caught in the spring or shaft during fall, which is a problem with the conventional vending machine, and even if a problem occurs in the product being caught inside the vending machine, it can be easily solved in terms of maintenance. There was an urgent need to develop a technology for an advantageous slot assembly for a vending machine.

In order to solve the above problems, the present invention is characterized in that the shaft provided at the center of the spring is omitted from the conventional slot assembly for a vending machine, and is provided in the vending machine to guide the rotation of the spring for discharging the product. Another object of the present invention is to provide a slot assembly for a vending machine capable of facilitating discharging of a product by guiding a product mounted on a spring.

According to an embodiment of the present invention, there is provided a slot assembly for a vending machine that is provided in a vending machine to discharge products, comprising: a housing forming an exterior of the slot assembly for the vending machine; a spring having a vertical length inside the housing and having a spiral shape on which a product is mounted; It may include a spring rotation motor for rotating the spring and a departure prevention guide provided inside the housing, formed at intervals corresponding to the diameter of the spring forming a spiral shape to support the front of the product.

In addition, the slot assembly for the vending machine may further include an auxiliary guide for guiding the fall by supporting the rear of the product mounted on the spring.

Also, the slot assembly for the vending machine may further include a body provided with an insertion groove into which one or more slot assemblies for the vending machine are inserted, and one or more bodies may be provided inside the vending machine.

In addition, the spring may include a spring pitch adjusting means for adjusting the height between the pitches formed by the spring by tensioning or contracting the spring with a compression cylinder coupled to the spring and moving up and down.

In addition, the slot assembly for the vending machine further includes an insertion guide inserted into the spring to support the lower surface of the product and falling together with the product, wherein the insertion guide is inserted between the gaps formed by the spring, and between the springs. It may be formed to a thickness smaller than the gap.

In addition, the slot assembly for the vending machine includes variable support means configured to vary according to the diameter of the product to support the product, and the variable support means uses an elastic force to extend the range of the variable support member in the outer direction of the product. resilient springs to expand; a wire controlled by a winding device provided inside the variable support member and contracting the variable support member in the direction of the product; and a size detection sensor provided at a predetermined position in the length direction of the wire to detect the size of the product. can
