Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a product storage column for a vending machine that sells cylindrical products such as cans and pins.

Conventional technology The general structure of a conventional product storage column is shown in Figures 6 to 9.
This will be explained with reference to the diagram.

In the figure, 1 is a vending machine main body, and a door 2 is provided on the front side. The interior of the main body 1 is divided into a storage room 4 and a machine room 6 by a partition wall 3. A product storage column e is provided in the storage chamber 4. This product storage column 6 has a plurality of partition plates 7 arranged approximately in parallel, and a plurality of connecting plates sa, sb and mounting plates arranged between them. Plate 9a,
9b.

They are connected to each other by 9C.

Additionally, within the product storage column e, there are four meandering product transport paths 10a that are alternately curved in the front and back and extend in the vertical direction.
, 10b, 10C, and 10d are juxtaposed in the front and back, respectively.The upper end of the intermediate goods conveyance path 108-10d has input ports 11a, 11b, 11C111 formed in four upper and lower stages.
d and input rails 12a, 12b, 12G, 12, respectively.
They are connected via d. Further, the lower end portion is a product ejection mechanism 13a.

13b, 13C, 13d and delivery chute 14
It communicates with a sales outlet (not shown) through. 1
6 is an evaporator for cooling the product, and 16 is an internal blower, which are disposed below the storage chamber 4.

The four product transport paths IC)a to 10d are formed by arranging a plurality of curved product guide plates 2o facing each other. The product guide plate 20 has a locking rod 2 provided between the partition plates 7 in its mounting hole 20a.
1 is inserted and supported between the partition plates 7. Furthermore, locking rod 2
1 is provided with a collar 2-b on one side to prevent removal.

In such a configuration, the assembly method is such that the locking rod 21
Through hole 7 of partition plate A at the right end where one end 21a is shown in FIG.
a, then fit the mounting hole 20a of the product guide plate 2o into the locking rod 21, and then in the same way, the plurality of partition plates 7 and the product guide plate 2° are alternately inserted into the locking rod 21. It is assembled by inserting the locking rod 21, and finally, a fixing member 22 such as a nut is attached to one end 21a of the locking rod 21, and the whole is tightened together.

Problems to be Solved by the Invention However, in the above configuration, the plurality of locking rods 21
The assembly requires a great deal of effort since it is necessary to fit and tighten fixing tools 22 such as nuts. Furthermore, since fitting and tightening the plurality of fixtures 22 is work, there is a problem in which nuts may not be properly attached, such as forgetting to tighten them.

The present invention has been made in view of the above-mentioned problems and provides for more efficient assembly of product storage columns.

Means for Solving the Problems In order to solve the above problems, the present invention provides a method in which the locking rods of a product storage column composed of a plurality of partition plates are provided with flanges on one side,
The other is provided with a locking piece that is deformed by heat.

For production The effect of this technical means is as follows.

In other words, the locking rods are securely fixed to the partition plate by passing the locking rods through the partition plate and the product guide plate and pushing and expanding the locking pieces of the last partition plate using a heat welding jig. Ash,
Furthermore, assembly work can be performed accurately and effectively.

EXAMPLE An example of the present invention will be described below with reference to FIGS. 1 to 6, but the locking rod is different from the conventional example.

Since the other configurations are the same, the same numbers will be assigned and detailed explanations thereof will be omitted.

Reference numeral 23 designates a partition plate at the outermost end of the product storage column 6, and is provided with a large number of insertion holes 24 that are the same as the through holes 7a of the other plurality of partition plates 7. 26 is made of thermoplastic resin and has a hollow part 2 on one side.
5a, the end on the side of the hollow portion 25a has a flange 25b provided in advance in the outer circumferential direction, and the other end forms a tapered locking piece 25c.

When assembling the product storage column 6, the hollow part 25a of the locking rod 26 is inserted into the pin 27 installed vertically on the base plate 26 with the flange 2sb as the lower end, and then,
Through hole 7a of partition plate 7 and mounting hole 20a of product guide plate 20
Insert the required number of partition plates 7 and product information plates 20 in order.
is inserted. In the final process step when the plurality of partition plates 7 and the product guide plate 20 are inserted into the locking rod 26, the outermost partition plate 23 is attached to one end 25c of the locking rod 25 as shown in FIG. applied to.

Thereafter, one end 25c of the locking rod 25 is pressurized using a heat welding jig 28 having a concave portion 28a at the tip and a built-in heater 29, and is thermally deformed into the shape of the tip concave portion 28a, and the locking piece 250 is The locking rod 26 is like a thermally deformed portion 2sd in contact with the partition plate 23, and both ends of the locking rod 26 are pressurized at the same time to integrally tighten and fix the locking rod 26 as a whole. In this way, the partition plate 23 and the locking piece 25c at one end of the locking rod 25 are heated,
By expanding the product storage column 6 by applying pressure, the product storage column 6 can be assembled easily and efficiently.

Effects of the Invention As described above, the present invention fixes the product storage column by expanding the ends of the partition plates after inserting them into the locking rods, and does not require the conventional fixing devices. Only the insertion of the locking rod is required, making assembly much easier than conventional methods. In addition, the hollow part of the locking rod is used to insert the locking rod into the protruding pin of the assembly jig, making it easy to manually insert the locking rod into the protruding pin of the assembly jig. In case of inserting the locking rod, or in the case of automation, automatic feeding is facilitated, greatly improving work efficiency, and eliminating the problem of forgetting to tighten the fixing tool.
