Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a beverage vending machine, and more specifically, it is capable of dispensing drinks such as instant coffee that suit the individual's taste to more people with a small opening. This invention relates to a beverage vending machine with a two-layered material stocker so that the material can be dispensed.

[Conventional technology]

As a beverage vending machine, as described in Utility Model Application No. 53-91183 and Utility Model Application No. 55-16056,
Multiple stockers containing powder raw materials are installed side by side,
A nozzle provided below the stocker and a screw conveyor are installed inside the stocker, and a shutter provided downward from the end of the nozzle feeds into the mixing bowl in conjunction with the rotation of the screw conveyor. Beverage vending machines are known that are configured to take out a predetermined amount of raw materials when opened, mix the raw materials with a predetermined amount of diluent to make a beverage, and vend the beverage automatically.

In this way, the beverage vending machines that are currently in practical use have a single-layer material stocker, which means that the number of material stockers is small and it is not possible to respond to the diversification of user tastes. Beverage vending machines had to be placed side by side in one place, or larger vending machines with larger widths and depths that could sell a variety of beverages had to be prepared.

[Problems to be Solved by the Invention] However, with this approach, there are problems in that the installation cost increases, and a large space for installation and a power supply corresponding to the number of vending machines are required.

Therefore, in order to store many raw materials in one beverage vending machine, for example,
As shown in the publication, the problem can be solved by stacking the raw material stocker in two layers instead of one layer.
Even with a simple two-layer stacked structure, when considering replenishment of raw materials, a stepladder must be used to raise and lower the upper stocker, and in particular, when replenishing the lower material stocker, the upper material stocker must also be raised and lowered. There is a problem.

The object of the present invention is to eliminate the problems of the above-mentioned conventional techniques, and to provide a beverage vending machine equipped with a material storage mechanism that has a large material storage capacity, easy material replenishment, and a small frontage. be.

[Means for solving problems]

The object of the present invention described above is to provide a pair of guide rails each having a U-shaped cross section and sloping downward in the front at the center of the inner upper part of the side plate of the casing. The upper material stocker is suspended on the guide rail by engaging pulleys pivotally mounted on the face plate, and the upper material stocker is wound on a motor winding drum provided on the front plate side of the case inside the ceiling plate of the case. The upper part of the upper material stocker is connected to the attached wire rope via a fixed pulley pivoted to the rear part of the upper inner surface of the side plate of the housing, and the upper material stocker is connected to the motor along the pair of guide rails. A pair of guide rails facing the depth direction of the casing and parallel to the bottom plate are installed inside the side plates, and a pulley is mounted on the bottom plate on the guide rail. A lower material stocker attached to both sides is movably mounted, a shutter for taking out the material is detachably attached to each of the material stockers, and a conical gear is attached to a screw conveyor provided in the upper material stocker. This can be achieved by providing meshable bevel gears of the motor attached to the back plate.

[Effect]

In the beverage vending machine of this invention, the upper and lower material stockers are vertically lined up, but when replenishing the upper material stocker with materials, the upper and lower material stockers can be The material stocker begins to move down along the guide rail and the bevel gear and disc gear are disengaged, and the upper material stocker further descends and maintains the lowered position.
