The present invention relates to an inner partition plate and a manufacturing method thereof.
[0002]
[Prior art]
FIG. 3 shows an internal partition plate of this type of conventional vending machine. This internal partition plate 21 is configured by interposing a rigid urethane foam as a heat insulating material between two vertically long rectangular metal plates (iron plates) 22 and 22. In this case, the metal plates 22 and 22 function as a moisture-proof layer for preventing deterioration of heat insulation due to the water droplets entering the hard urethane foam even if water droplets are formed on the surface of the internal partition plate 21 due to condensation. To do. As a result, the internal partition plate 21 has a heat insulating property and a moisture proof property which are functions required for itself.
[0003]
This internal partition plate 21 is manufactured as follows. That is, first, the two metal plates 22 and 22 are overlapped with a predetermined gap therebetween, and a seal 23 is attached between the four peripheral edges of the metal plates 22 and 22. Next, liquid urethane is filled into the space 24 surrounded by both the metal plates 22 and 22 and the seal 23 from the outside through the urethane inlet 25 opened to the space 24. Thereafter, by foaming this urethane, a rigid urethane foam is formed in the entire space 24, and a predetermined long side portion of both the metal plates 22, 22, that is, the internal partition plate 21, is stored in a commodity storage (not shown). A packing 26 made of rubber or the like is attached over the entire long side portion that becomes the front side when attached to the inside of the. Thereby, the internal partition plate 21 is completed.
[0004]
The in-compartment partition plate 21 manufactured in this way is attached to the product storage compartment so as to partition the inside of the product storage compartment to the left and right by a mounting bracket (not shown). More specifically, a partition seal 27 having a width substantially the same as the thickness of the internal partition plate 21 is provided at a position where the internal partition plate 21 is to be attached over the ceiling surface, back surface, and bottom surface in the product storage. It is attached in the shape of a letter, and is attached to the inside of the product storage with the partition wall 21 being pressed against the partition seal 27. When, for example, one such partition plate 21 is attached in the product storage case, when the front surface of the product storage unit is closed by a heat insulation door (not shown), the partition plate on the back side of the heat insulation door is provided. The packing 26 at the front end of the 21 abuts, thereby forming two storage chambers that are both airtight in the product storage. Then, by installing a cooling device and a heating device in these storage chambers, respectively, the two storage chambers are used as a cooling chamber and a warming chamber, respectively. For example, cooling products such as soft drinks are placed in the cooling chamber in the heating chamber. Stores hot products such as canned coffee.
[0005]
[Problems to be solved by the invention]
As described above, when the internal partition plate 21 is manufactured, urethane is injected into the space 24 between the two metal plates 22 and 22 at the time of manufacture, and this is foamed. Manufacturing takes time and contributes to high costs. In addition, the metal plate 22 needs to have a certain thickness in order to be able to withstand foaming of urethane and to secure strength as the internal partition plate 21. As the height increases, the internal partition plate 21 itself becomes heavy. Further, in the in-compartment partition plate 21 manufactured as described above, the two metal plates 22 and 22 and the rigid urethane foam are firmly bonded to each other due to self-adhesiveness due to foaming of urethane at the time of manufacture. For this reason, there is also a problem that the work of disassembling the metal plate 22 and the hard urethane foam becomes very complicated when the internal partition plate 21 is recycled.
[0006]
The present invention has been made to solve the above-described problems, and can be manufactured efficiently and at low cost, and can be easily disassembled at the time of recycling or the like. It aims at providing a partition plate and its manufacturing method.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings. 1 and 2 show an exploded view and an assembled view, respectively, of an interior partition plate of a vending machine according to an embodiment of the present invention. This compartment partition plate 1 partitions a product storage in a vending machine (not shown) into a plurality of storage chambers on the left and right, and in particular, the product storage is a cooling chamber in which cooling products such as soft drinks are stored. And a heated greenhouse in which heated products such as canned coffee are stored. The internal partition plate 1 includes a vertically long rectangular partition plate main body 2, reinforcing frames 3 provided at the four peripheral edges of the partition plate main body 2 in order to reinforce the partition plate main body 2, and a front frame described later of the reinforcing frame 3. The packing 4 attached to the portion 16 is configured.
[0015]
As shown in FIG. 1B, the partition plate body 2 includes a hard urethane foam 11 having a certain thickness and formed in a vertically long rectangular shape as a base material having heat insulation properties. One of the lower corners of the rigid urethane foam 11 is cut out so as to fit into the shape of the lower end of the front surface of the product storage (not shown). In addition, the surface of the rigid urethane foam 11, more specifically, the surfaces facing the cooling chamber and the warming chamber when the internal partition plate 1 is attached to the product storage room (hereinafter, these surfaces are combined to represent “ As shown in FIG. 1B, a moisture-proof layer 10 in which a moisture-proof paper 12 and an aluminum foil 13 are sequentially laminated is provided.
[0016]
The moisture-proof paper 12 prevents moisture (water droplets) from entering the rigid urethane foam 11 due to condensation, and prevents warpage of the rigid urethane foam 11 due to a temperature difference between the front and back surfaces by tension. Accordingly, when the internal partition plate 1 is installed in the product storage compartment and partitions the cooling chamber and the heating chamber, the rigid urethane foam 11 is formed by reliably preventing moisture from entering the rigid urethane foam 11. The internal partition plate 1 can always be kept in an appropriate posture without warping without causing a decrease in the heat insulating property of the internal partition plate 1 (hard urethane foam 11) due to moisture absorption.
[0017]
On the other hand, the aluminum foil 13, similarly to the moisture-proof paper 12, prevents moisture from entering the rigid urethane foam 11, prevents air from passing through the rigid urethane foam 11, and reflects radiant heat. At the same time, the front and back surfaces of the partition plate body 2 are finished cleanly. Therefore, when the internal partition plate 1 is installed in the product storage and partitions the cooling chamber and the heating chamber, the flow of air between the cooling chamber and the heating chamber is reliably blocked, By reflecting the radiant heat, the heat retaining properties of the cooling chamber and the heating chamber can be improved.
[0018]
The reinforcing frame 3 is made of, for example, a metal material such as iron or aluminum, and has an upper frame portion 14 attached to the upper end edge portion, the lower end edge portion, the front end edge portion, and the rear end edge portion of the partition plate body 2, respectively, The frame 15, the front frame 16, and the rear frame 17 are configured. The upper frame part 14, the lower frame part 15, and the rear frame part 17 are all formed in a U-shaped cross section, and are fitted and attached so as to cover the entire edges of the partition plate body 2. It is like that. In addition, the upper frame part 14, the lower frame part 15 and the rear frame part 17 are connected to each other, and the whole is matched to the shape and size of the upper edge part, the lower edge part and the rear edge part of the partition plate body 2. It is almost U-shaped. In addition, screw holes 14a and 15a are formed at the front end portions of the upper frame portion 14 and the lower frame portion 15, respectively. When the reinforcing frame 3 is attached to the partition plate body 2, these screw holes 14a and 15a are formed. Accordingly, the front frame portion 16 is screwed to the upper frame portion 14 and the lower frame portion 15.
[0019]
In the front frame portion 16, similarly to the other frame portions 14, 15, and 17 described above, a concave portion 16 a having a U-shaped cross section for fitting into the front end edge portion of the partition plate body 2 while being covered. Is formed along the front frame portion 16. In addition, a fitting groove 16b having a C-shaped cross section is formed along the front frame portion 16 so as to be back-to-back with the concave portion 16a. Further, through holes 16c and 16c for screwing the front frame portion 16 to the upper frame portion 14 and the lower frame portion 15 are formed at both ends of the front frame portion 16, respectively.
[0020]
When the partition plate 1 is attached in the product storage, and the partition 4 is divided into a cooling chamber and a greenhouse, the packing 4 is insulated when the front of the product storage is closed by a heat insulating door (not shown). This is for shutting off the flow of air between the cooling chamber and the heating chamber in the vicinity of the front end of the internal partition plate 1 by abutting on the rear surface of the inside. The packing 4 is made of, for example, an elastic material such as rubber. As shown in FIG. 1A, the packing 4 is slightly longer than the front frame 16 and has a cross section formed in an ant tenon, and the mounting portion. Adjacent to 4a, the cross section is formed in an annular shape, and is constituted by an abutting portion 4b that abuts against the above-described insulating door when it is closed. In addition, when attaching this packing 4 to the front frame part 16, the edge part of the attachment part 4a of the packing 4 is inserted from one end of the fitting groove 16b of the front frame part 16. FIG. Thereby, as shown in FIG. 2, the packing 4 is firmly attached to the front frame portion 16.
[0021]
Here, the manufacturing method of the partition plate 1 in a store | warehouse | chamber, especially the manufacturing method of the partition plate main body 2 is demonstrated. First, the raw material urethane is foamed, and the rigid urethane foam 11 is molded while extruding it with a desired thickness using, for example, an extruder. And the moisture-proof layer 10 which consists of moisture-proof paper 12 and the aluminum foil 13 is laminated | stacked on the front and back of this rigid urethane foam 11, respectively. Specifically, after the moisture-proof paper 12 is pasted on the front and back surfaces of the rigid urethane foam 11, an aluminum foil 13 is laminated on the surface of the moisture-proof paper 12 by vapor deposition. In addition, after laminating the aluminum foil 13 by vapor deposition on one side of the moisture-proof paper 12, the moisture-proof layer 10 may be attached to the front and back surfaces of the rigid urethane foam 11.
[0022]
In the manufacture of the partition plate body 2, the rigid urethane foam 11 is molded to a desired dimension, and then the moisture-proof layer 10 is laminated on the front and back surfaces, and the moisture-proof layer is simultaneously extruded from the extrusion machine. 10 may be laminated. In this case, since the moisture-proof layer 10 is composed of the moisture-proof paper 12 and the aluminum foil 13, the hard urethane foam 11 having the moisture-proof layer 10 on the front and back surfaces is adjusted to a desired size by using an appropriate cutting machine. The partition plate body 2 having a desired dimension can be easily obtained by appropriately cutting.
[0023]
And while attaching the said reinforcement frame 3 to the partition plate main body 2 manufactured as mentioned above, the packing 4 is attached to the front frame part 16 of the reinforcement frame 3, and the partition plate 1 in a warehouse is completed (FIG. 2). reference). When installing this partitioning plate 1 in the product storage, prior to the mounting, a partition seal 18 having a width substantially the same as the thickness of the partitioning plate 1 is attached in the product storage as in the prior art. At the position where the internal partition plate 1 should be attached over the ceiling surface, the back surface and the bottom surface, it is attached in a U-shaped side section. And in the state which pressed the partition plate 1 against the partition seal 18, it attaches in a goods storage via the attachment bracket which is not shown in figure. Thereby, the inside of the product storage can be divided into two left and right storage chambers, and for example, one storage chamber can be used as a cooling chamber and the other storage chamber can be used as a heating chamber.
[0024]
As described above in detail, according to the internal partition plate 1 of the present embodiment and the manufacturing method thereof, the rigid urethane foam 11 is preliminarily molded, and the moisture-proof layer 10 is laminated on the front and back surfaces of the rigid urethane foam 11, The internal partition plate 1 thus obtained has the heat insulation and moisture resistance required as functions of the internal partition plate 1. In addition, since the hard urethane foam molded in a predetermined shape is used in the manufacture of the internal partition plate 1, unlike the conventional case, no foaming work or the like at the manufacturing site is required, and for example, commercially available mass-produced by extrusion. It is also possible to use a rigid urethane foam, and as a result, the internal partition plate 1 can be manufactured efficiently and at low cost. Further, since the moisture-proof layer 10 is stuck and laminated on the front and back surfaces of the rigid urethane foam 11, the moisture-proof layer 10 is made of the rigid urethane foam, unlike the case where the moisture-proof layer 10 is bonded by utilizing self-adhesive property due to foaming of urethane. 11 can be easily peeled off. This makes it possible to easily disassemble the moisture-proof layer 10 and the rigid urethane foam 11 when recycling the internal partition plate 1 or the like. Furthermore, since the moisture-proof paper 12 and the aluminum foil 13 are used as the moisture-proof layer 10, the interior partition plate 1 can be reduced in weight and the workability of the partition plate body 2 can be improved as compared with the case where a conventional iron plate is used. In addition, the storage chamber can be expanded by the amount that the moisture-proof layer can be made thinner.
[0025]
In addition, this invention can be implemented in various aspects, without being limited to the said embodiment described. For example, although hard urethane foam is used as the substrate, other materials may be used as long as they have heat insulation properties and a certain degree of rigidity. Further, although moisture-proof paper and aluminum foil are used as the moisture-proof layer, a metal plate such as a thin iron plate may be used instead. Furthermore, the rigid urethane foam may be molded by an appropriate molding method other than extrusion.
[0026]
In addition, the detailed configuration of the interior partition plate 1 shown in the embodiment is merely an example, and can be appropriately changed within the scope of the gist of the present invention.
