Description

  The present invention relates to a casing of a vending machine, in particular, a structure of an outer box for constructing the casing, and an assembling method thereof.

As is well known, a cabinet of a vending machine has a structure in which an outer door and an inner door are combined with a box-shaped steel plate casing and a commodity storage rack is mounted in the cabinet. In addition, the outer box that constructs the housing must be secured to the inside of the outer box body to ensure sufficient mechanical strength due to the load on the product storage rack, outer door, and inner door. It is made of a structure in which members are assembled and this reinforcing member is reinforced by welding to the outer box main body (see, for example, Patent Document 1).
Depending on the type of product being sold, the vending machine's casing is a non-insulated structure that consists of an outer box with an inner box and an outer box filled with a heat insulating material, or an outer box alone. There is a sex case.
Next, the structure of the conventional vending machine casing (outer box) and its assembling method will be described with reference to FIGS. First, FIGS. 4A and 4B show the structure of the outer box 1. In the figure, reference numeral 2 denotes an outer box body obtained by processing a steel plate into a U-shape according to the outside size of the vending machine (height: about 1.8 m, width: about 1.1 m, depth: about 0.7 m), 3 Is a back plate that covers the back of the outer box 2, 4 is a base assembly provided at the bottom of the outer box body 2, and 5 is an upper reinforcement welded to the inside of the front opening along the top plate of the outer box body 2. Gold (upper reinforcing member), 6 is a rear reinforcing metal (rear reinforcing member) welded to the rear end side of the top plate, and 7 is welded to the inner walls of the left and right side walls of the outer box main body 2 connected to both ends of the upper reinforcing metal 5 Reference numeral 8 denotes a bottom plate that is disposed on the bottom side of the outer box body and partitions the base assembly 4.

Here, the upper reinforcing metal 5 and the side reinforcing metal 7 are long corrugated plates obtained by processing a steel plate so that the cross-sectional shape thereof is corrugated as shown in FIGS. The length corresponding to the outer dimension of the box body 2 is set. In particular, the side reinforcing metal 7 laid on the left and right side surfaces of the outer box body 2 is a long body having a length of about 1.8 m. Although not shown, the product storage rack is suspended and supported between the upper reinforcing metal 5 and the rear reinforcing metal 6 and a door gasket is laid on the front and side reinforcing metal. I am doing so.
On the other hand, in the assembly process for constructing the outer box 1, first, the reinforcing metal 5, 6, 7 is temporarily fixed at a predetermined assembly position on the inner side of the outer box body 2 processed into a U-shaped sheet metal. Spot welding is performed between the reinforcing bars 5, 6, and 7 and the outer box body 2 by a welding machine. Thereafter, the back plate 3, the base assembly 4, and the bottom plate 8 are assembled so that the outer box 1 is assembled.

Further, in the welding process for assembling the reinforcing bars 5, 6 and 7 to the outer box body 2, the upper reinforcing bar 5 having a short length is first removed while the outer box body 2 is laid down as shown in FIG. Attached to the inside of the top plate of the box body 2, it is positioned at a predetermined position, and fixed at this position by a clamp (hand-operated tightening jig). Subsequently, using a manual welding machine, spot welding (spot welding location W) is performed on several locations of the upper reinforcing metal 5 and temporarily clamped to the outer box body 2, and then the clamp is removed. Next, the long side reinforcement 7 is attached to the inside of the outer box body 2 in the same procedure as described above, and the top end of the upper side is abutted against the end of the upper reinforcement 5 to be positioned at a predetermined assembly position. Then, the two ends of the reinforcing metal are fixed to the outer box body 2 with the clamps 9 as shown in the figure, and in this state, several points of the side reinforcing metal 7 are spot welded to the outer box main body 2 to form the outer box main body 2. Temporarily fix and remove the clamp 9. Further, the rear reinforcement 6 (see FIG. 4) is also temporarily fixed to the outer box body 2 in the same procedure as described above. Thereafter, the temporary assembly is loaded into an automatic welding machine, and the reinforcing bars 5, 6, and 7 temporarily fixed to the outer box body 2 are spot-welded over the entire length thereof.
JP 2000-94141 A

By the way, the conventional method for assembling the outer box 1 by the above-described work procedure has the following problems in terms of work efficiency and production cost. In other words, after the side reinforcement 7 of a long heavy object having a length as long as 1.8 m is manually positioned at a predetermined assembly position, the two ends thereof are simultaneously fixed by the clamps 9 at the work site. Since it is difficult to perform by one worker alone, positioning of the side reinforcing metal 7 and tightening of the clamp 9 are conventionally performed by two workers.
However, as described above, injecting two workers in the process of temporarily fixing the side reinforcing metal 7 to the outer box main body 2 at a predetermined position is inefficient in work, and this increases the cost. Therefore, the improvement measures are required as a request from the manufacturing site.
The present invention has been made in view of the above points. The object of the present invention is to solve the above-mentioned problems, and to attach a long side reinforcing metal to a predetermined side in an assembly process of welding the upper and side reinforcing members to the inside of the outer box body. It is an object of the present invention to provide a vending machine housing assembly structure improved and an assembling method thereof so that even one worker can easily perform the operation of positioning and clamping at the assembly position.

In order to achieve the above object, according to the present invention, an upper reinforcing member and left and right side reinforcing members are laid along the inner peripheral edge of the front opening of the outer casing body made of steel plate, In the case of the vending machine that has an assembly structure spot welded to the outer box body,
Positioning and locking means for locking and holding the upper ends of the side reinforcing members at the left and right ends of the upper reinforcing member positioned at a predetermined assembly position and temporarily fixed to the outer box body in the welding process of the reinforcing member. (Claim 1) Specifically, as a positioning locking means for the side reinforcing member, an engaging protrusion is provided on the upper end side of the side reinforcing member, and both ends of the upper reinforcing member are opposed to the engaging protrusion. A positioning engagement hole is formed in the portion (claim 2).
In the assembly process of the housing in which the upper and side reinforcing members are welded to the outer box body, the upper reinforcing member is first positioned at a predetermined assembly position and temporarily fixed to the outer box, and then the side reinforcing member The engaging protrusion provided on the upper end side is inserted into the engaging hole of the upper reinforcing member and held in this position, and the other end of the side reinforcing member is clamped to the outer box body to be in a predetermined assembly position. The upper reinforcing metal and the side reinforcing member are spot welded to the outer box main body over the entire length in the temporarily assembled state in this temporarily assembled state (Claim 3).

  By adopting the above assembly structure and assembly method, in the assembly process in which the long side reinforcing member is positioned and temporarily fixed at a predetermined position of the outer box body, it is possible to perform joint work of two workers as in the past. The operation of positioning and clamping the side reinforcing members can be easily performed by one worker without reliance, thereby improving the work efficiency and reducing the cost.
