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. Drink 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 drinks had to be prepared.

[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 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 point.

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 opening. It is.

[Means for Solving the Problems] The purpose of this invention described above is to provide a pair of guide rails each having a U-shaped cross section and sloping downward from the front at the center of the inner upper part of the side plate of the casing. , the upper material stocker is suspended from the guide rails by engaging pulleys pivotally mounted on both side plates of the upper material stocker with these guide rails, and The upper part of the upper material stocker is connected to a wire rope attached to a lifting shock absorbing mechanism composed of a spiral spring provided on the front plate side via a fixed pulley pivotally supported at the rear part of the upper inner surface of the side plate of the casing. The upper material stocker is arranged so as to be slowly movable along the pair of guide rails by the lifting buffer mechanism, and the upper material stocker is attached to a locking hook provided on the inner surface of the upper part of the side plate of the housing. The upper material stocker is configured to be engaged with a locking pin protruding from the side plate to maintain the upper position of the upper material stocker, and to be able to lower the upper material stocker along the pair of guide rails by releasing the engagement. Further, a pair of guide rails extending parallel to the bottom plate in the depth direction of the casing are attached to the inside of the side plates, and a lower material stocker having pulleys attached to both sides of the bottom plate is movable on the guide rails. This can be achieved by removably equipping each material stocker with a shutter for taking out the material.

[Function] The beverage vending machine of this invention is used with the upper and lower material stockers lined up vertically, but when replenishing the upper material stocker with ingredients, remove the shutter and then use the spiral spring. By removing the locking hook from the locking pin of the upper material stocker and slowly lowering it along the guide rail, the upper material stocker can be slowly lowered by lowering the upper material stocker slowly. The stotzka maintains its lowered position by its own gravity.

In this state, the lid of the upper material stocker can be opened, each material is put in, and after the lid is closed, the upper material stocker can be returned along the guide rail, and the locking pin engages with the locking hook and the upper The upper position of the material stocker is maintained.

Furthermore, when replenishing material in the lower material stocker, the shooters of each material stocker are removed, and the lower material stocker is pulled toward you, allowing it to move horizontally along the guide rails toward the front panel. In this state, the lid of the lower material stocker is opened, the material is placed in each, and after closing the lid, it is returned to its original position, allowing material to be replenished in each of the upper and lower material stockers at the same height relatively low in the housing.
