Description

Description: BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a structure of a case base provided on a bottom side of a main body case of a vending machine. 2. Description of the Related Art First, a schematic configuration of a vending machine to which the present invention is applied is shown in FIG. In the drawing, 1 is a main body case of a vending machine, 2 is a front outer door, 3 is a heat insulating inner door, 4
Reference numeral denotes a product rack (a serpentine-type product rack) housed in the storage of the main body case 1; In addition, the vending machine is a heavy object having a total weight of several hundred kg, and in order to stably support the main body case of such a heavy object, the case body 1 is provided with a highly rigid case base 7 on its bottom side. And the base 7
The vending machine is mounted on the installation surface via the support legs 8 standing at the four corners of the vending machine. FIG. 5 shows a conventional assembling structure of the case base 7 described above. That is, the case base 7 includes a base body 9 based on a frame-shaped outer frame attached to the inner peripheral side of the case body 1, and a sheet metal reinforcing member 10 welded to the base body 9. . Further, the reinforcing member 10 is formed of a channel-shaped front reinforcing metal 10a and a rear reinforcing metal 10b attached to the front and rear of the outer frame of the base body 9 and an intermediate reinforcing metal 10c extending between the two reinforcing metals. After assembling the three parts, the space between the reinforcing metal members 10a and 10b and the base body 9
The reinforcing metals 10a, 10b, and 10c are respectively assembled by spot welding, TIG welding, or the like. In the above-described conventional structure of the case base 7, three independent parts made of sheet metal are employed as the reinforcing member 10, and the reinforcing member 10 is provided between the base body 9 and the base member 9. The parts are welded together and assembled. For this reason, there are the following difficulties in terms of manufacturing. That is, 1) Since each part is individually processed by sheet metal processing, the number of processes including cutting and bending of the material is large, and many waste ends are generated. [0005] 2) In addition, the number of parts is large, so that there are many welds. Especially, the intermediate reinforcing metal requires a lot of time for assembling work because the mounting position is adjusted and welding is performed manually.
Deformation of the base due to welding distortion also increased, and the body case 1
There is also a problem of assemblability such as difficulty in assembling into a device. The present invention has been made in view of the above points,
It is an object of the present invention to solve the above-mentioned problems and to provide a case base of a vending machine which can be manufactured inexpensively with a small number of parts and welding points. According to the present invention, there is provided a base body based on a frame-shaped outer frame attached to the bottom of a case body, and a base body. Intermediate reinforcement consisting of a welded-in reinforcement member, and the reinforcement member is joined to the front and rear portions of the outer frame of the base body, the front reinforcement and the rear reinforcement, and the front reinforcement and the rear reinforcement. For the case base combined with gold,
Rear reinforcement, middle reinforcement, and reinforcements formed on side edges
The strong rib portion is integrated by drawing to form a single component, and the component is assembled by welding to the outer frame of the base body. [0007] With the above structure, the number of reinforcing members for the case base is reduced from three parts to one or two parts in the related art, and the number of welding points for attaching to the base body is greatly reduced. As a result, the number of steps is reduced, the yield of parts is improved, and the deformation of the base due to welding distortion is reduced, so that the assemblability is improved. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to the drawings according to the above-described embodiments. In the drawings of the respective embodiments, the same members corresponding to FIG. 5 are denoted by the same reference numerals. Embodiment 1 FIGS. 1A and 1B show an embodiment corresponding to claim 1 of the present invention. In this embodiment, instead of the front reinforcement 10a, the rear reinforcement 10b, and the intermediate reinforcement 10c, which are three parts used in the conventional structure of FIG. A case base 7 is assembled by welding a reinforcing metal 11 as a part and welding the reinforcing metal 11 to the inner peripheral side of the base body 9. In FIG. 1A, a welded portion between the base body 9 and the reinforcing metal 11 is indicated by a hatched portion W. The reinforcing metal 11 is made by drawing a steel plate, and has a front portion 11a and a rear portion 11a.
b and the intermediate portion 11c correspond to the front reinforcing metal 10a, the rear reinforcing metal 10b, and the intermediate reinforcing metal 10c of the above-described independent components, respectively, and 11d is a reinforcing rib portion formed on a side edge portion by drawing. [Embodiment 2] FIG. 2 shows an embodiment according to claim 2 of the present invention. In this embodiment, the base body 9
A reinforcing member 12 is manufactured by drawing as a single component obtained by integrating a front reinforcing member 10a and an intermediate reinforcing member 10c in FIG. 5, and a rear reinforcing member 13 similar to the rear reinforcing member 10b in FIG. These parts are combined with the base body 9 as shown in the figure, and between the front side of the outer frame of the base body 9 and the front part 12a of the reinforcing metal 12, the rear side of the outer frame and the rear part. Between the reinforcing metal 13 and the intermediate portion 12 of the reinforcing metal 12
The case base 7 is assembled by welding between b and the rear reinforcing metal 13. [Embodiment 3] FIG. 3 shows an embodiment according to claim 3 of the present invention. In this embodiment, the reinforcing member of the base body 9 includes a reinforcing metal 14 which is manufactured by drawing as a single component integrating the rear reinforcing metal 10b and the intermediate reinforcing metal 10c in FIG. It consists of two parts, a front reinforcement 15 similar to the reinforcement 10c,
These parts are combined with the base body 9 as shown in the figure, and between the rear side of the outer frame of the base body 9 and the rear part 14a of the reinforcing metal 14, between the front side of the outer frame and the front reinforcing metal 15, Then, the case base 7 is assembled by welding the intermediate portion 14 b of the reinforcing metal 14 and the front reinforcing metal 15. As described above, according to the structure of the present invention, the following effects can be obtained as compared with the conventional structure. 1) The number of parts of the reinforcing member provided on the base body of the case base is reduced from the conventional three parts to one or two parts, and the number of welding points is also reduced. This reduces manufacturing and assembly man-hours,
In addition, the yield of parts is improved and the production cost can be reduced, and unnecessary deformation of the case base due to welding distortion is reduced, so that the assemblability when mounting to the main body case is improved. 2) Further, the reinforcing metal as a single part can be drawn, requires less man-hours than the conventional one in which individual parts are manufactured by sheet metal processing, and is used for assembling into a base body. In addition, since the positioning is simple, it is possible to greatly contribute to improvement of productivity, for example, automation of welding by a robot is easy.
