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 with a two-layered material stocker so that it can be dispensed.

[Conventional technology]

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.

[Problem that the invention attempts to solve]

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 if the material is simply stacked in two layers, 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 problems]

The purpose of this invention described above is to provide a pair of support plates via pulleys on a pair of guide rails arranged in the depth direction at the top of the housing, and to attach a reducer and a A screwdrive type elevating mechanism is provided, which includes a reversible drive device consisting of a directional motor, a shaft rotated by the reversible drive device, and a screw screw rod equipped with bevel gears that mesh with bevel gears attached to both ends of the shaft, The screw screw is screwed into a female screw member attached to the side plate of the upper material stocker to make the upper material stocker a hanging type, and also capable of being raised and lowered by the screw drive type lifting mechanism, and disposed at the bottom of the casing. This is achieved by suspending the lower material stocker by engaging pulleys provided on the side surfaces of the lower material stocker, respectively, with guide rails provided approximately at the center of the housing.

[Effect]

After removing the shooter, the upper material stocker is moved to the front plate side along the guide rail attached to the side plate, and when the reversible drive device is operated, it screws into the female thread member attached to the side of the upper material stocker. The screwdrive type lifting mechanism is configured such that the screw screw is rotated, and the lower material stocker can be lowered quietly in front of the material stocker.

When the supply of raw materials is finished in this upper material stocker, the reversible drive device is reversed to raise it again.
Once it has finished rising, it can be moved along the guide rail toward the back plate and returned to its original position.

The lower material stocker can be moved from the back plate side to the front plate side on the guide rail, and both the upper and lower material stockers can be replenished with material at the same height relatively at the lower part.

In addition, 7 in the figure is the upper lid of the housing 2 that can be opened and closed, 24,
Reference numeral 25 denotes a removable material dispenser attached to each material storage chamber, which can take out a fixed amount of material by rotating a valve and a bend motor (not shown). Further, the lower part of the upper material stocker 14 is rotatably supported on a rail 14B by a pulley 14A.

The beverage vending machine of this invention has the above-mentioned structure, and the cases of replenishing and repairing materials will be described below.

Figure 5 shows the lifting mechanism 3 on the guide rails 4a and 4b.
The upper material stocker 14 suspended by the
It can be moved to the left end of the housing by pulling it to the left from the normal position in the housing 2 shown in the figure. Similarly, the lower material stocker 15 and the box 21, which are suspended by the guide rails 5a to 5d and 6a to 6d, are pulled to the left from their fixed positions in the casing 2 shown in FIG. It can be moved up to. Similarly, if the lower material stocker 15 and the box 21 suspended by the guide rails 5a to 5d and 6a to 6d are pulled to the left from their fixed positions in the housing 2 shown in FIG. As shown in FIG. 7, it can be moved to the left end of the housing 2.

Furthermore, as shown in FIG.
4 to the left and escape from the rail 14B, the shafts 30a, 30b and the bevel gears 31a, 31b are turned on by energizing the reversible drive device 29.
The upper material stocker 14 is lowered to the height of the lower material stocker 15 by rotating the screw rods 33a and 33b, which are screwed in opposite directions, by means of 32a and 32b, and this lowered state is maintained by a limit switch (not shown). .

From this lowered position, by reversing the reversible drive 29, it can be raised to a position where the upper limit switch (not shown) is actuated. It can be lowered.

By lowering the upper material stocker 14 to the height of the lower material stocker 15 in this way, it is possible to easily replenish materials into the storage chamber of the upper material stocker 14, even when the materials are usually stacked vertically. Individual replenishment of materials into the upper and lower material stockers 14, 15 and repair of the boxes can be easily performed by removing the upper cover 7 from a relatively lower portion of the housing 2.

In addition, although each of the guide rails 4a to 4d to 6a to 6d is shown as a flat rail, each of these rails is made into an angular rail, and the pulleys 18a to 18f to 23a to
By using a pulley having a V groove as 23f, each material stocker can be smoothly moved without coming off the track.

In addition, the raw material and diluent may be poured into a sales cup CUP and sold.

[Effect of idea]

As described above, this invention adopts a means to solve the above problems, and therefore, materials are replenished into the material storage chambers of each of the upper and lower material stockers at a relatively lower part of the casing. This makes it possible to carry out the process without using a stepladder, and it also becomes possible to sell a wide variety of beverages without increasing the width of the housing.

In addition, by providing a screwdrive type lifting mechanism, the upper material stocker can be lifted and lowered using an inexpensive one-way motor by operating a reversible drive.
It can be implemented at a low cost, and since there is no stacking element, the movement of the above-mentioned upper and lower material stockers can be performed smoothly and easily, and the installation space can be small.

In addition, since the upper material stocker can be vertically lowered or raised, there is no need to cut off the front upper part of the lower material stocker, and the amount of material stored in the lower material stocker can be maximized. have an effect.
