  As vending machines for paper packs, cans, bottles, and plastic bottle products, vending machines equipped with drawer-type direct stacking racks in the cabinet of the main body cabinet are known (for example, see Patent Document 1), and the conventional automatic 10 and 11 show the schematic structure of the vending machine and the drawer-type direct rack mounted in the warehouse.

  First, FIG. 10 is an overall configuration diagram of a vending machine, wherein 1 is a main body cabinet, 2 is an outer door arranged on the front surface, 3 is a heat insulating inner door, 3a is a commodity outlet for the heat insulating inner door 3, A plurality of product storage chambers are defined in the cabinet of 1 through partition plates 4 standing up and down on the left and right, and a drawer-type direct stack rack that is pulled out to the front of the cabinet for product supply and maintenance work. 5 is installed. Reference numeral 6 denotes a guide rail that is laid on the side surface of the internal partition plate 4 and guides the direct stack rack 5 in the drawing direction indicated by the arrow P.

  11 is an assembly structure diagram of the direct stack rack 5. In the figure, reference numerals 7 and 8 denote upper and lower rack frames, and 9 denotes a plurality of column units between the rack frames 7 and 8 in a horizontal row. A column unit assembly 10 constructed side by side is a bend mechanism 10 provided on the product carry-out end side of each column unit (the structure and operation of the bend mechanism are described in detail in Patent Document 1, and the description thereof is omitted here. ), 11 is a column door for product replenishment arranged in front of the column passage for each column unit, and the product stacked and stored in the passage in the column is supported from the front by the column door 11 in the closed position. The direct rack 5 is supported by hanging the upper rack frame 7 on a rail laid on the top plate side in the cabinet, and the lower rack frame 8 is a guide rail laid on the partition plate 4 so as to prevent the rack from rolling. 6 is guided and supported in the pull-out direction.

  Next, a conventional mounting structure for the column door 11 (Patent Document 1) will be described with reference to FIG. That is, the column door 11 is a sheet metal product of a steel plate, and the upper and lower edges of the long door plate are curled to form the hinge shafts 11a and 11b. The hinge shafts 11a and 11b are connected to the upper rack frame 7. The shaft is supported so as to be opened and closed by being inserted into bearing holes 7a and 8a drilled in a flange portion protruding from the lower rack frame 8 to the side. Further, in order to hook the column door 11 in the closed position, an engagement square hole 11c is opened at the upper end portion of the door plate, and the engagement square hole 11c is formed in the flange portion of the upper rack frame 7. The column door 11 is held in the closed position by being hooked on the engaging claws 7b (see FIG. 12B).

  In addition to the bearing hole 8a, the lower rack frame 8 has a tongue-shaped opening / closing guide 8b standing upward from the flange, and protrudes upward from the terminal position of the opening / closing guide 8b to open the column door 11 to the open position.

JP 2006-11612 A

The conventional vending machine described above includes a stopper that stops the column door 11 provided in the direct stack rack 5 at the open position, and a guide rail 6 that is laid on the partition plate 4 and guides the direct stack rack 5 in the pull-out direction. There are the following issues regarding the laying structure.
(1) First, the conventional column door 11 shown in FIG. 12 has a required strength, which is a sheet-metal processed product of a single steel plate in which hinge shaft portions 11a and 11b are formed by curling the upper and lower edges. It is made using a steel plate with a thickness of about 1mm from the top.

  By the way, since the recent increase in the price of steel materials has also affected the product cost, it has become an urgent issue to reduce the material cost by reducing the thickness of the door plate of the column door. However, if a column door with the same structure as a conventional product is made of a steel plate that is thinner than the conventional product (for example, 0.6 mm thick), the machine of the hinge shaft part where load is repeatedly applied as the door is opened and closed. There is a problem that sufficient strength cannot be secured. Therefore, recently, the column door is divided into a long door plate and hinge shafts connected to the upper and lower ends of the door plate, and a thin steel plate with a thickness of 0.6 mm is used for the door plate. On the other hand, a column door product that uses the same 1 mm thick steel plate as the conventional one to reduce the material cost of the door has appeared in the hinge shaft where the load accompanying the door opening / closing operation is applied.

  However, the column door having the above-described structure in which the door plate is thinned and separated from the hinge shaft portion is adopted in the conventional direct stack rack shown in FIG. 11, and the product replenishment work is actually performed to verify the door opening / closing operability. However, it turned out that there were the following problems.

  That is, as the thickness of the steel plate is reduced, the strength of the door plate, in particular, the strength of the central portion of the long door plate that is long in the vertical direction is lowered against bending and twisting. On the other hand, when opening the column door when replenishing products to the direct rack, many workers often stand in a standing position and open the door vigorously by putting their hands on the upper end side of the column door that is easy to grip. is there.

  In this case, as described in FIG. 12, in the conventional structure, the stopper 8c is formed on the lower rack frame 8 as a means for restraining the column door 11 to the open position, and the lower end of the door plate is pushed into the stopper 8c when the door is opened. The column door 11 is stopped to the open position.

However, if the upper end side of the column door 11 is squeezed open with a hand, the upper end side of the door plate remains at the predetermined open position shown in FIG. 12 even after the lower end side of the door plate hits the stopper 8c and is stopped at the open position. Beyond the point, it bends further to the open side, resulting in twisting and warping of the door plate. In addition, the twist and warp generated in the door plate are not completely restored even when the hand is released from the door, and the door plate is deformed. In such a state, even if the column door 11 is closed, the column door 11 is not completely closed due to the influence of the deformation, so that the stacked posture of the products stored in the column is disturbed and the products are clogged. In addition to incurring sales troubles such as the product unloading operation not being performed normally, the deformed part of the door plate protrudes to the side of the direct stack rack 5 and interferes with the adjacent direct stack rack, internal partition plate, etc. There is a possibility that it may interfere with the drawer operation of the direct rack.
(2) Also, with respect to the guide rail laid on the inner partition plate so as to guide the drawer-type direct stack rack mounted in the warehouse, the conventional rail mounting structure shown in FIG. The guide rail is fixed at a predetermined position using a total of three screws. For this reason, it takes time to assemble the guide rail, particularly the screw tightening operation, and therefore, an improvement measure is demanded.

  The present invention has been made in view of the above points, and an object of the present invention is to improve a guide rail that is laid on an internal partition plate and guides a direct stack rack in the pull-out direction so that the number of assembly steps and the number of parts can be reduced. It is to provide a rail laying structure.

  In order to achieve the first object, according to the present invention, the guide rail laid on the internal partition plate so as to guide the direct rack mounted in the storage in the pull-out direction, the rear end of the guide rail, And an insertion tab in a direction orthogonal to each other at the front end, and a pocket-shaped tab holder is cut and raised on the partition plate corresponding to the insertion tab, and the insertion tab is inserted into the tab holder. After the insertion tab is inserted and the guide rail is positioned at the laying position, one screw is screwed between one of the tab receivers and the insertion tab and fixed at a predetermined position.

According to said structure, there can exist the following effect.
(1) With respect to the guide rail laid on the partition plate in the cabinet so as to guide the direct rack mounted in the vending machine cabinet in the pull-out direction, the screw tightening operation can be reduced by adopting the laying structure according to the present invention. Only a few parts are required, and the assembly cost can be reduced by reducing the number of assembly steps and parts compared to the conventional structure.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below based on illustrated examples described below.

  First, FIGS. 1 to 5 show the construction of an embodiment according to claims 1 to 3 of the present invention. In the drawings of the illustrated embodiment, the same members corresponding to those in FIGS. 11 and 12 are denoted by the same reference numerals and description thereof is omitted.

  In this embodiment, the column door 11 includes a door plate 11-1 made of a thin steel plate (for example, a thickness of 0.6 mm) and upper and lower ends of the door plate 11-1 as shown in the exploded view of FIG. The hinge reinforcing plates 11-2 and 11-3 having a thickness of about 1 mm, which are overlapped and fastened to each other, are divided into three parts, and a conventional structure (see FIG. 12) is provided on the side edges of the hinge reinforcing plates 11-2 and 11-3. The hinge shafts 11a and 12b are formed by curling as in the case of the reference).

  The rack frames 7 and 8 assembled on the top and bottom of the direct stack rack 5 have bearing holes 8a, opening and closing guides 8b similar to those of the conventional structure (see FIG. 12) at the flanges protruding laterally from the lower rack frame 8. And a stopper 8c is formed.

  On the other hand, the upper rack frame 7 is newly provided with a tab-like stopper 7c that hangs in an L shape on the opposite side of the engaging claw 7b across the bearing hole 7a. This stopper 7c is positioned vertically corresponding to the stopper 8c formed on the lower rack frame 8, and when the column door 11 is opened, it abuts against the plate surface of the hinge reinforcing plate 11-2 and the upper end of the column door 11 is It is positioned and arranged so as to stop at a predetermined open position (see FIG. 1B).

  With the above configuration, when the column door 11 is opened for replenishing goods (see FIGS. 4 and 5), the upper end of the door hits the stopper 7c formed on the upper rack frame 7, and at the same time the lower end of the door is the lower end rack. The column door 11 comes into contact with the stopper 8c formed on the frame 8 and is stopped at the predetermined opening position shown in FIG.

  Therefore, even when an operator puts his hand on the upper part of the door plate when opening the column door 11, the upper end of the door does not overshoot beyond a predetermined open position, and the thin steel plate is used. It is possible to avoid the column door 11 from being deformed due to unnecessary twisting and warping of the door plate 11-1 produced.

  As a result, the door plate of the column door 11 is thinned to reduce the material cost, and when the door is opened by opening the door by placing a hand on the upper end side of the door plate, the door plate is not twisted or warped. Suppresses the occurrence and stops the upper and lower ends of the door plate at the specified open positions, causing trouble in product sales due to deformation of the door plate, and the deformed column door interferes with adjacent racks, partition plates, etc. As a result, it is possible to improve the handling and reliability of the column door by avoiding the problem that it is difficult to pull out the direct rack.

  Next, an embodiment of the guide rail of the direct stacking rack according to claim 4 of the present invention will be described with reference to FIGS. 6A to 6C are explanatory views showing the guide rail mounting procedure, and FIGS. 7, 8, and 9 are structural diagrams of individual components in FIG. 6, corresponding to FIG. The same reference numerals are used for the members to be described, and the description thereof is omitted.

  That is, with respect to the guide rail 6 (see FIG. 10) that is attached to the internal partition plate 4 of the vending machine and guides the direct stack rack 5 in the pull-out direction, in this embodiment, at the rear end and the front end of the guide rail 6 Insertion tabs 6c and 6d that are orthogonal to each other are formed in a cutout, and a screw hole 6d-1 is drilled at one place of the insertion tab 6d on the front end side.

  Further, pocket-shaped tab receivers 4a and 4b are cut and raised at predetermined positions determined on the plate surface of the internal partition plate 4 in correspondence with the insertion tabs 6c and 6d. Here, in the tab receiver 4a, the slit-shaped insertion groove 4a-1 opens toward the front in the cabinet (see FIG. 8), and in the tab receiver 4b, the insertion groove 4b-1 opens downward, and the A screw through hole 4c is opened at the center of the tab receiver 4b (see FIG. 9).

  In order to lay the guide rail 6 on the internal partition plate 4 with the above configuration, first, the insertion tab 6c formed at the rear end of the guide rail 6 as shown in FIG. Insert and hold. Next, as shown in FIG. 6B, the front end portion of the guide rail 6 is moved upward to insert the insertion tab 6d into the tab receiver 4b. In this state, one set screw 13 and the screw hole 6d-1 are inserted. And the guide rail 6 is fixed to a predetermined laying position.

  According to this rail laying structure, the number of assembling steps and the number of parts can be reduced as compared with the conventional structure described with reference to FIG. 13, and troublesome screw hole alignment is not required, and the assembling workability is improved.
