Description

[Detailed Description of the Invention] The present invention relates to the structure of a cup accommodating portion of a drinking water vending machine or the like.

In recent years, various types of vending machines have become popular, and many of them are now in use, dispensing drinking water or the like into a cup provided with the vending machine.

This type of vending machine is equipped with a cup storage cylinder for storing cups, and the stored cups are taken out one by one from the bottom end.

For this reason, each vending machine is equipped with a cup storage tube that matches the diameter of the cup being used, and when using a cup with a different diameter, the cup storage tube must be replaced, which is extremely troublesome. Not only that, but it also had problems such as being uneconomical.

In view of the above-mentioned drawbacks, the present invention was developed with the aim of eliminating this problem.The present invention is designed to expand according to the inner diameter of the cup storage cylinder, whose diameter can be adjusted according to the diameter of the cup being used. Alternatively, it is an object of the present invention to provide a structure of a cup accommodating portion which is narrow and is provided with a push-down plate that comes into contact with the upper surface of the cup to push it down.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings. FIG. 1 is a front view of a cup accommodating portion, and FIG. 2 is an enlarged sectional view of the same essential part.

The housing cylinder 1 is made by winding a thin plate into a cylindrical shape, and the housing cylinder 1 has a small hole bored around the upper end of the overlapping part and a small hole bored in the opposite wall.
Insert the bent inner ends 3a, 3a of the pivot wire member 3 through a small hole made in the edge of the lid body 2 that loosely fits into one end,
It is constructed as a cylindrical body whose diameter at the other end can be expanded or narrowed.

Near the lower end of the housing cylinder 1, a plurality of locking protrusions 4, 4, . A pair of elongated holes 6, 6 are formed from the inside, and elongated holes 6.6 extending in the circumferential direction with respect to both edges and having different inclination directions are bored at corresponding positions. Bolt 7 inserted into
A wing nut 8 is screwed and fastened to the cup housing cylinder 1 to form a cup housing cylinder which can be adjusted to a desired lower end diameter by adjusting the overlapping amount of the lower end of the housing cylinder 1.

The cup push-down mechanism 9'' that slides inside the housing tube 1 bends both ends of the base member 10, which is sufficiently shorter than the inner diameter of the housing tube 1, and fixes it to the lower end of the coil spring 11, and also fixes the upper end of the coil spring 11 to the lower end of the coil spring 11. is in contact with the inner surface of the lid 2 to elastically urge the base member 10 downwardly of the housing cylinder 1.

Sliding members 13 and 13 are respectively inserted into the slide holes 12 bored near both ends of the base member 10 so as to be slidable in the radial direction, and the sliding end portion 14 bent in an L-shape is inserted into the housing cylinder 1. The rain shelter member 13.13 comes into contact with the inner wall of the
The rain shelter end 14.1 is always elastically biased in the outer radial direction by a U-shaped leaf spring 15 whose end is inserted inside the rain shelter end 14.1.
4 is brought into close contact with the inner wall of the housing cylinder 1.

16 is a chain connected between the upper rod part of the coil spring 11 and the center part of the leaf spring 15, and the chain 16 is connected to the position where the cup pressing mechanism 9 does not go beyond the locking protrusions 4.4. Adjust the length.

Note that a in the figure is a cup to be accommodated, and the edges of the cup a are lightly engaged with the engagement protrusions 4, 4, . . . .

To obtain the cup accommodating portion configured as described above, loosen the wing nut 8 of the cylinder diameter adjustment mechanism 5, and adjust the engagement between the locking protrusions 4, 4... and the edge of the cup a according to the diameter of the cup a to be used. After adjusting the condition, a large number of stacked cups a are accommodated, and the edge of the lowest cup a is engaged and supported by the locking protrusions 4.4. When cup a is pulled strongly, the edge part is pulled out past the locking protrusions 4.4, and the next edge part of cup a is locked by the locking protrusions 4, 4, etc., and the cup A is taken out one by one.

At this time, the sliding end 14.14 provided on the base member 10 of the cup push-down mechanism 9 comes to press the edge of the uppermost cup a by the elasticity of the coil spring 11, so the cups a are sequentially fed out. It is something.

Further, the lower end of the housing cylinder 1 is narrowed by the cylinder diameter adjustment mechanism 5, and the inner diameter becomes gradually smaller.
5, the sliding end 1 is always elastically biased outward.
4. 14 comes to slide closely against the inner wall of the housing cylinder 1, the sliding ends 14, 14 do not come off from the edge of the cup a, and the cups a are successively pushed down to the last one. It is something.

As explained above, according to the structure of the cup storage part of the drinking water vending machine, etc. of the present invention, the cylinder diameter of the locking part is changed according to the cup to be used by the cylinder diameter adjustment mechanism of the storage cylinder.
In addition, the sliding diameter of the cup push-down mechanism can be changed according to the cylinder diameter, so that the edge of the uppermost cup is always pressed with an appropriate pressure regardless of the amount of cups accommodated. This allows you to take out every last piece.

Furthermore, since the cup accommodating section of the present invention has an extremely simple structure, there are few accidents such as breakdowns, and it can be provided at a low cost, resulting in extremely large practical effects.
