Description

[Detailed explanation of the invention] [Industrial application field] This invention relates to a beverage vending machine, and more specifically, it allows more people to enjoy drinks such as instant coffee that suit their tastes in a small space. 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, this approach has problems in that it increases installation costs, requires a large space for installation, and requires 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 the replenishment of raw materials, a stepladder must be used to raise and lower the upper material 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 storage capacity for materials, facilitates replenishment of materials, and has a small frontage. It is.

[Means for Solving the Problems] In order to achieve the above-mentioned purpose, the beverage vending machine of this invention has a U-shaped cross section attached to the inside of the side panel of the housing, is linear, and slopes downward toward the front. Two pairs of pulleys each having an upper material stocker attached to its side plate are fitted onto a pair of inclined guide rails so as to be movable up and down, and the upper material stocker is pivotally supported at the rear upper part of the casing. A locking pin is attached to the upper front part of the housing via a wire rope passing through the housing, and is connected to a lifting/lowering buffer mechanism composed of a spiral spring, and is provided protruding from a side plate of the upper material stocker. The upper material stocker is held in the upper position by being engaged with a retaining hook pivotally supported on the side plate, and further, by releasing the above-mentioned retaining, the upper material stocker is moved along the guide rail and moved by the lifting shock absorbing mechanism. This is achieved by movably placing a lower material stocker which is configured to be able to be lowered slowly and further has a pulley at the bottom on a pair of guide rails attached to the lower part of the inner surface of the side plate.

[Function] To replenish the upper material stocker in the beverage vending machine of this invention, remove the shooter and then remove the locking hook that is locked to the locking pin provided on the upper material stocker. is guided by a guide rail, and can be lowered to the front of the lower material stocker while being prevented from rapidly descending by the lifting buffer mechanism, and this lowered position is maintained by the self-gravity of the upper material stocker.

After replenishing the material, when the upper material stocker is lifted, the locking pin engages with the locking hook, and the upper position of the upper material stocker is maintained.

The lower material stocker can be moved from the back plate 8 side to the front plate 9 side of the housing 2 on the guide rails 6a and 6b, and can be returned to its original position after replenishing the material.
