Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a beverage vending machine, and more specifically, it is capable of dispensing drinks such as instant coffee to more people in a small space to suit their tastes. This invention relates to a beverage vending machine that has a material stocker with a two-layer structure so that the material stocker can be dispensed.

[Prior Art] 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 the replenishment of raw materials, a stepladder must be used to raise and lower the upper material stocker, and especially 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 storage capacity for materials, facilitates replenishment of materials, and has a small frontage. It is.

[Means for Solving the Problems] An object of the present invention described above is to arrange a pair of guide rails each having a U-shaped cross section, slanting downward toward the front, and curving outward, on the inside of the side plate of the casing. At the same time, a pair of pulleys pivotally provided on the upper part of the side plate of the upper material stocker are engaged with these guide rails so that the upper material stocker can be raised and lowered along the guide rails, and the side plate of the housing is A locking hook pivotally attached to the upper part of the upper material stocker is engaged with a locking pin protruding from a side plate of the upper material stocker to maintain the upper position of the upper material stocker, and when the engagement is released, the upper material stocker is held in the upper position. This can be achieved by configuring the stocker so that it can be lowered along the guide rail, and further by movably installing the lower material stocker via a pulley on a pair of guide rails provided at the inner lower part of the side plate.

[Function] The beverage vending machine of the present invention is used with the upper and lower material stockers lined up vertically, but when replenishing the upper material stocker with materials, the shutter must be removed and then locked. If the hook is removed from the locking pin and the upper material stocker is pulled down along the curved guide rail, the upper material stocker will maintain its lowered position by its own gravity.

In this state, after putting the material into the upper material stocker, if you lift the upper material stocker, the upper material stocker can be returned along the curved guide rail, and the locking pin engages with the locking hook to the upper position. hold.

Furthermore, when replenishing material to the lower material stocker, remove the shutters of the upper and lower stockers, and then pull the lower material stocker toward you to move it horizontally on the guide rail toward the front plate. After filling the lower material stocker with material in this state, it is only necessary to return it to the regular position, and the upper and lower material stockers can be refilled with material at the same height at a relatively lower portion of the housing.
