Description

[Detailed description of the invention] [Industrial application field] This invention relates to a beverage vending machine, and more specifically, it allows more people to dispense drinks such as instant coffee that suit their tastes through a small opening. This invention relates to a beverage vending machine with a two-layered material stocker so that the material 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 screw conveyor is inserted into the mixing bowl from a shutter provided downward from the end of the nozzle in conjunction with the rotation of the screw conveyor. BACKGROUND ART Beverage vending machines are known in which a predetermined amount of raw materials can be taken out when the shutter is opened, and the materials are mixed with a predetermined amount of diluent to make a beverage and then vended automatically.

In this way, the beverage vending machines currently in practical use have a single-layer material storage structure, so they are small in number and cannot respond to the diversification of user tastes. It was necessary to install beverage vending machines in one place, or to prepare larger vending machines with larger widths and depths that could sell a wide variety of beverages.

[Problems to be Solved by the Invention] However, such a solution increases the installation cost and requires a large space for installation and a power source corresponding to the number of vending machines.

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 purpose of this 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. It is.

[Means for Solving the Problems] The purpose of this invention described above is to supply materials into a mixing bowl through shutters that are removably installed in a plurality of material stockers that are divided into upper and lower layers inside the housing. In a beverage vending machine that dispenses beverages, mixes them with diluted liquid, and sells them, a pair of guide rails each having a U-shaped cross section and sloping downward from the front and being curved is disposed at the center of the upper inner side of the side panel of the housing. and pulleys pivotally provided on both side plates of the upper material stocker are respectively engaged with these guide rails so that the upper material stocker can be raised and lowered,
Furthermore, a pair of pulleys is attached to the rear panel side of the casing inside the ceiling plate of the casing, and each of these pulleys has a weight at one end, and a pair of pulleys each having a weight at one end and the upper material stocker attached to the other end. A wire rope was stretched and provided, and a pair of guide rails extending parallel to the bottom plate in the depth direction of the casing was attached to the inside of the side plates, and pulleys were attached to the guide rails on both sides of the bottom plate. A lower material stocker is movably mounted, a shutter for taking out materials is detachably attached to each of the material stockers, and a shutter is attached to a disc gear and a back plate attached to a screw conveyor provided in the upper material stocker. The lower position of the upper material stocker is fixed by engaging the locking hook provided on the side plate of the housing with the locking pin protruding from the side plate of the material stocker. This can be achieved by configuring the upper material stocker to be able to rise along the guide rail by holding the material and releasing the engagement.
