Description

[Detailed Description of the Invention] The present invention relates to an improvement of a cup accommodating cylinder for a drinking water vending machine or the like.

Some vending machines for drinking water etc. store cups and use them as containers, but this type of cup storage tube is used by pulling out the bottom cup one by one. A locking protrusion protruding from the inner wall near the lower end of the housing cylinder is configured to lock onto the edge of the cup.

Therefore, it is necessary to prepare accommodating cylinders with internal diameters that suit each type of cup diameter, which has the drawback of having to replace and readjust the cup accommodating cylinder in the vending machine every time the diameter of the cup used changes. Was.

The present invention has been devised in view of the above-mentioned drawbacks, and is intended to eliminate the above drawbacks, and is intended to provide a cup accommodating cylinder for a vending machine or the like that can accommodate cups of various outside diameters.

Hereinafter, one embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an exploded perspective view of a cup accommodating cylinder, and FIG. 2 is a partially cutaway front view.

The housing cylinder main body 1 is made of a thin plate rolled into a cylindrical shape, and has small holes 3, 3 at the upper end of the overlapping part 2, and another small hole 4 at a position opposite to these small holes 3, 3, and the upper end of the main body 1. The inner end bent portion 7 of the pivot wire member 7 has the end bent portions 7a inserted into a small hole 6.6 made in the edge 5a of the lid 5 which is loosely fitted into the
The small holes 3, 3 and 4 are inserted into the holes 3, 7a to form a cylindrical body, and the lower end can be adjusted to widen or narrow.

In addition, a locking protrusion 8 slightly protruding in the inner diameter direction is located near the lower end.
．． Several holes 9, 9, etc. are arranged in parallel in the circumferential direction, and elongated holes 9, 9, which extend in the circumferential direction and have mutually different inclination directions, are provided on both edges of the overlapping portion 2. The wing nuts 11 are screwed onto the bolts 10 inserted into the pair of elongated holes 9 and 9 from the inside, and after adjusting the amount of overlap at the lower end of the main body 1, the bolts are tightened to set the desired lower end. A cup accommodating cylinder having a diameter is configured.

A coil spring 12 whose upper end is in contact with the lid 5 and is elastically biased downward is housed in the housing cylinder, and the lower end of the coil spring 12 always slides in close contact with the inner wall. A chain 1 is provided between the leaf spring 15 provided on the base member 14 of the cup push-down board 13 and the lid body 5 at the lower limit position of the cup push-down board 13.
6 are connected.

The cup push-down board 13 has slide holes 17.17 bored near both ends of the base member 14, both ends of which are wound and fixed around the coil springs 12, and each end is bent downward into the slide holes 17.17. A sliding member 18.18 formed by the above is provided so as to be slidable in the radial direction, and a leaf spring 15 bent in a U-shape is internally locked between the rain shelter members 18.18. .18 is elastically biased so that it always slides into contact with the inner wall of the main body 1.

In the figure, a is the cup, b is the edge of the cup, and 19
is a mounting member for mounting the housing cylinder main body 1 to a vending machine (not shown).

The cup housing cylinder configured as described above is made by strongly pushing in a large number of stacked cups a from the lower end of the cylindrical body 1, and then using the coil spring 12.
The cup pressing board 13 that is in contact with the edge of the cup A is moved upwardly against the elasticity of the cup A to fill the cup.
The edges of the housing are locked by the locking protrusions 8, 8, and are stored and held.

In addition, when the lowermost cup a is strongly pulled during use, its edge comes off from the locking protrusions 8, 8, etc., and at the same time the edge of the next cup a, which is pushed down by the elasticity of the coil spring 12, are engaged with the locking protrusions 8, 8, . . . , and only one cup a can be taken out.

Therefore, the housing cylinder main body 1 must be adjusted to have an inner diameter that allows the locking projections 8 to sufficiently lock the edges in accordance with the diameters of the various cups a. The provided wing nut 11 can be easily adapted by loosening it, adjusting it to the desired diameter, and then tightening it again.

At this time, the main body 1 is connected to the small hole 3 on the overlapping part 2 side of the pivot wire member 7.
, 3 is used as a fulcrum to widen and narrow the lower end, and since the elongated holes 9, 9 are inclined in different directions, it is easy to see the overlapping part of both elongated holes 9, 9, and the insertion of the bolt 10 is facilitated. It's extremely easy.

Next, FIG. 5 shows another embodiment of the expansion adjustment part of the main body 1, in which a bolt 10' is erected outward from the inner overlap part end of the overlap part 2 near the lower end of the main body 1, and at the same time, A long hole 9' extending in the circumferential direction is bored in the outer overlapping part of the position corresponding to the bolt 10', and the wing nut 11 is inserted therethrough.
' has been concluded.

As explained above, the cup storage cylinder of the present invention can be adapted to various cups of vending machines etc. with different diameters by adjusting the inner diameter of the main body, and even if the cup is changed, the cup storage cylinder can be replaced. There is no need to do this, and the practical effects of implementing the present invention are extremely large, such as having a simple configuration and being able to be provided at low cost.
