Abstract

PURPOSE:To eliminate need for cutting and removal to overall length by folding at least one-side parts of both sides of a strip like metallic plate inward by length corresponding to the finish height of the case for a automatic vending and matching the height of the height of the 1st member to the finish height. CONSTITUTION:A material drawn out of a coil material 11 is cut in pieces of length (2L+W) and parts A, B, C, etc., are punched in specific shapes. Parts d1-d5 of the metallic plates 8 are bent inward to form flange parts ej-e5 and bent laterally at two parts of folding lines 9 and 10 to form a 1st member 12, which is fitted with a 2nd member 13 as a ceiling plate and a 3rd member 14 as a base plate to form the case 7 for the automatic vending machine. Consequently, even when the metallic plate is larger than the finish height of the case for the automatic vending machine, the finish height of the case for the automatic vending machine can be coped with without cutting and removing the metallic plate to its overall length.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a method of manufacturing a case for a vending machine, in which a door is attached to the front opening to constitute an exterior case of the vending machine.

BACKGROUND ART As shown in FIG. 2, a vending machine case 7, which is surrounded by a back plate 1, side plates 2, 3, a top plate 4, and a base plate 5 and has an opening 6 formed in the front, is conventional. Sheet metal processing is performed using the following process.

Here, the finished height of the vending machine case 7 is H
Assuming that 1 width is W1 and depth is L, in step I, as shown in FIG.
is prepared, and in step (2), bend this metal plate 8 along lines 9 and 1.
The vending machine case 7 is made by vertically bending it at two points 0 and then, in step (2), attaching a back plate 1 and a substrate 5 to the vertically bent product in step (2).

As shown in FIG. 3, the metal plate 8 is manufactured by purchasing sheet materials cut out to a predetermined size in advance, stacking them, and then taking them out one by one and repeating step (2).
There are two manufacturing methods: purchase a coil material with a width of L, and repeat step (2) while cutting the material drawn from the coil material into lengths (2H1W).

In recent years, there has been a trend toward production of multiple models in small quantities, and although the height H is almost constant depending on the model, the width W and depth vary widely. In the conventional configuration as described above, by adopting a manufacturing method that repeats step (2) while cutting the material drawn from the coil material into lengths (2H + W), it is possible to make the desired size in step (2). , it is necessary to prepare small items such as the back plate 1 and the board 5 with dimensions for each model, but the height H of the vending machine case 7
Changes in the width W can be easily accommodated. However, it is not possible to deal with changes in the depth of the vending machine case 7, and it is necessary to prepare coil materials with different widths for each model of depth.

Therefore, as shown in Fig. 4, in step I, the material drawn from the coil material U, which has a width that is approximately the same as the finished height H, is cut into lengths (2L+W), and in step II, this metal plate 8 is bent. The first member 12 is made by bending it horizontally at two points, line 9 and IO. Next, in step 2, a second member z3 for the top plate is attached to the first member 12 made by horizontally bending in step It is conceivable that the third member for the circuit board [4] be attached to form the case 7 for a vending machine.

In this method, by assembling and configuring the first to third members 12 to I4, the first member 12 can be created from the same coil material even if the models have different widths W and depths. , the second item for each model with different width W and depth. Although the third members 13 and 14 must be prepared, there is no need to prepare coil materials with different widths for each model, which reduces material costs and facilitates storage and management.

Problem to be Solved by the Invention However, even with the method shown in FIG. 4, if the height H is smaller than the width of the coil material 11, one side of the metal plate 8 cut out from the coil material II is It is necessary to cut and remove the unnecessary width over the entire length (2L+W) and then perform the horizontal bending in step (2).

This operation of cutting and removing one side of the metal plate 8 along its entire length requires a long processing time with a processing machine, and is not suitable for mass production.

The present invention enables sheet metal processing by horizontally bending a metal plate, even if the metal plate is larger than the finished height of a vending machine case, without cutting and removing the entire length of the metal plate.
To provide a method for manufacturing a vending machine case that can correspond to the finished height of the vending machine case.

Means for Solving the Problems The method of manufacturing a vending machine case of the present invention includes forming an upper part of a first member which is formed by horizontally bending a band-shaped metal plate to form a back plate and both side plates adjacent to the back plate. When manufacturing a vending machine case by attaching a second member for the top plate and a third member for the board to the lower part, at least the parts on both sides of the band-shaped metal plate that will be in the height direction of the case when finished are Bend one side inward by a length that corresponds to the finished height of the case, then bend this metal plate horizontally at two places to make the first member. The second member and the third member for the board are attached.

Effect: According to this configuration, at least one side of both sides of the band-shaped metal plate is bent inward by a length corresponding to the finished height of the case, so that the height of the first member is adjusted to the finished height of the vending machine case. There is no need to cut and remove the entire length to fit the exact specifications.

EXAMPLES Hereinafter, the method for manufacturing a vending machine case of the present invention will be explained based on specific examples. Components having the same functions as those shown in FIGS. 2 to 4 described above will be described with the same reference numerals.

The method for manufacturing a vending machine case of the present invention is manufactured through the steps shown in FIG.

In step I, the length of the material drawn from the coil material 11 (
2L x W) and punch out parts A, B, C, etc. into a predetermined shape. Here, it is the width of the coil material 11. is larger than the height H of the first member 12, and the dimensions h+ and h2 are processed as follows.

h, = h2 = (Lo-H)/2 And the parts dL, d of the metal plate 8 punched out in this way
2. d3. d4. Bend d5 inward to create flange part e
l+ e2+ e3t e4+ ers are formed, and in step (2), this metal plate 8 is laterally bent at two points, bending line 9 and IO, to make the first member 12, and then in step (2), this metal plate 8 is laterally bent in step (2). A second member 13 for the top plate and a third member 14 for the board are attached to the first member 12 made as shown in FIG.

Here, the third member 14 is placed on the flange parts e and -e3, and the flange parts e1 to e3 and the third member 14 are spot welded. The second member I3 is attached to the flange portion e4 with the bent portion I5 in contact with the outside of the back plate portion of the first member 12. It is inserted under eI5, and spot welding is performed between the flange portions e4+e15 and the second member I3.

A door is attached to the front opening 6 of the vending machine case 7 assembled in this way, as in the conventional case, thereby forming an exterior case of the vending machine.

Because it is configured like this, the width is wide. The flange parts e1 to e are made according to the height H of the vending machine case made from the metal plate 8 of
By changing the dimensions hI and h2 of 5, the first member 12 of the vending machine case with different heights H can be made from the same coil material 11.

In the above embodiment, the flange parts eI-e5 were formed on the top plate side and the substrate side of the first member 12, and the dimensions were set to hl"h2, but this could be made ≠h2, or the first member I2 It is also possible to form a flange portion having dimensions (L, -H) only on one of the top plate side and the substrate side, so that the difference between the width of the coil material 11 and the finished height H can be relieved.

In the above embodiment, the metal plate 8 was repeatedly cut out from the coil material II, but if the width W and depth are constant, the metal plate 8 may be supplied as a sheet material as shown in FIG. You can also do it. However, in this case, when handling models with different widths W and depths, it is necessary to easily prepare sheet materials of different lengths for each model.

Effects of the Invention As described above, according to the present invention, a top plate is provided on the upper and lower parts of the first member, which is formed by horizontally bending a band-shaped metal plate to form a back plate and both side plates adjacent to the back plate. the second member and the third for the substrate
When manufacturing a vending machine case by attaching the members, at least one side of both sides of the band-shaped metal plate, which will be in the height direction of the case when finished, is attached to the inner side by a length corresponding to the finished height of the case. Since the first member is made by bending the metal plate in two places and then folding the metal plate horizontally in two places, it is possible to make the first member of various finished heights from the metal plate of a single width. This method requires less processing time than a process in which the metal plate is cut and removed by a predetermined width over its entire length, and is effective when mass-producing cases for vending machines that are produced in small quantities with a wide variety of models. .
