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] The above-mentioned object of the present invention is to provide a pair of guide rails each having a U-shaped cross section and sloping downward in the front on the inside of the side plate of the casing, and Two pairs of pulleys pivotally mounted on the side plates of the upper material stocker are engaged with the guide rail of the upper material stocker so that the upper material stocker can be moved up and down. A drive control member made of a rope is provided at the upper part of the housing, and the upper material stocker is configured to be movable up and down along the guide rail by the drive control member. This is achieved by installing the lower material stocker movably on the guide rail via a pulley.

[Function] The beverage vending machine of the present invention is used with the upper and lower material stockers arranged vertically, but when replenishing the upper material stocker with materials, the shutter is removed and then the drive When the control member is actuated, the upper material stocker can be lowered along the guide rail, and the upper material stocker is held in the lowered position by its own gravity.

After putting the material into the upper material stocker in this state, by reversing the drive control member, the upper material stocker can be returned along the guide rail.

Furthermore, when replenishing material to the lower material stocker, remove the shutters of the lower material stocker and the upper material stocker, and then pull the lower material stocker toward you so that it can be moved horizontally on the guide rail toward the front plate. In this state, it is only necessary to put the material into the lower material stocker and return it to the normal position, and the material can be replenished into each of the upper and lower material stockers at the same height at a relatively lower part of the housing.
