Description

  The present invention relates to an internal partition plate for partitioning a product storage in a vending machine into a plurality of storage rooms and a method for manufacturing the same, and particularly to a vending machine suitable for partitioning a product storage into a cooling chamber and a heating chamber. The present invention relates to an inner partition plate, a manufacturing method thereof, and a vending machine.

  Conventionally, as an internal partition plate of this type of vending machine, there are those shown in FIGS. 6 and 7 (for example, Patent Document 1).

  FIGS. 6 and 7 show an exploded view and an assembly view, respectively, of the interior partition plate of the conventional vending machine. 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 20, reinforcing frames 30 provided at the four peripheral edges of the partition plate main body 20 in order to reinforce the partition plate main body 20, and a front frame described later of the reinforcing frame 30. It is comprised by the packing 40 etc. which were attached to the part 16. FIG.

  The partition plate body 20 includes a hard urethane foam 21 having a certain thickness and a vertically long rectangular shape as a base material having heat insulation properties.

  The reinforcing frame 30 is made of, for example, a metal material such as iron or aluminum, and has an upper frame portion 14 and a lower frame that are respectively attached to the upper end edge, lower end edge, front end edge, and rear end edge of the partition plate body 20. 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 20. It is like that.

  The upper frame portion 14, the lower frame portion 15 and the rear frame portion 17 are connected to each other, and are almost entirely aligned with the shapes and dimensions of the upper edge portion, the lower edge portion and the rear edge portion of the partition plate body 20. It is formed in a letter shape. Further, 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 30 is attached to the partition plate body 20, 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.

  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 20 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.

  The packing 40 is made of, for example, an elastic material such as rubber, and is slightly longer than the front frame portion 16 and has a mounting section 40a having a cross section formed in a dovetail, and the mounting section 40a is adjacent to the mounting section 40a and has a circular section. And the abutting portion 40b that abuts against the above-described insulating door when the insulating door is closed. In addition, when attaching this packing 40 to the front frame part 16, the edge part of the attachment part 40a of the packing 40 is inserted from one end of the fitting groove 16b of the front frame part 16. Thereby, the packing 40 is attached to the front frame portion 16.

  In this way, the reinforcing frame 30 is attached to the partition plate body 20, and the packing 4 is attached to the front frame portion 16 of the reinforcing frame 30, thereby completing the internal partition plate 1. When installing the interior partition plate 1 in the product storage, prior to the installation, the partition seal 18 having a width substantially the same as the thickness of the interior partition plate 1 is attached to the ceiling surface, the rear surface, and the interior of the product storage. At the position where the internal partition plate 1 is to be attached over the bottom, 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. When, for example, one such partition plate 1 is attached in the product storage case, when the front surface of the product storage unit is closed by a heat insulating door (not shown), the partition plate on the back side of the heat insulation door is provided. The packing 40 at the front end of the first 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.

Further, as a proposal to use a vacuum heat insulating plate to improve the heat insulating performance of the internal partition plate, for example, as shown in Patent Document 2, after the vacuum heat insulating plate is accommodated in the partition plate, a heat insulator is filled, and the vacuum heat insulating plate is There is a proposal to embed it so as to wrap it.
JP 2002-32842 A JP-A-11-167670

  However, in the conventional configuration shown in Patent Document 1, a reinforcing frame made of a metal material is attached to the outer periphery of the base material of the internal partition plate, and is further attached to the product storage through a partition seal. This is a cause of heat leakage to the adjacent storage room. Moreover, since the periphery of the base material is a reinforcing frame made of a metal material, for example, when the base material dimension is short, the gap between the base material and the reinforcing frame cannot be filled with the dimensional variation of the base material. Leakage occurs.

  Moreover, in the conventional structure shown by patent document 2, a vacuum heat insulation board and a heat insulating body adhere | attach firmly mutually by the self-adhesiveness of a heat insulating body. For this reason, there is a problem that separation and disassembly work of the vacuum heat insulating plate and the heat insulator becomes very complicated at the time of recycling or the like.

  In addition, when the entire base material is a vacuum heat insulating plate, the vacuum heat insulating plate is formed by pulling a vacuum when sealing the core material (heat insulating core material) inside the bag-shaped outer cover material. It is held in a vacuum state. Since the jacket material is large enough to cover and accommodate the core material, the jacket material after the core material is sealed may be folded or a fin-shaped fin portion may be generated around the core material. Even if the fin portion is bent and the core material itself is used as a base material, there is a problem that the dimensional variation is large and the reliability cannot be secured.

  In addition, the vacuum heat insulating plate is deteriorated in heat insulation performance due to an increase in internal pressure due to the intrusion of air from the jacket material into the inside. The air intrusion is particularly large from the welded portion where the outer and outer jacket materials are welded, and the deterioration rate increases as the temperature increases. Therefore, there is a problem that the heat insulation performance is likely to be deteriorated when the fin portion is exposed to a high temperature greenhouse.

The present invention solves the above-described conventional problems, reduces heat leaks between storage chambers, and ensures high sealing performance between storage chambers even with respect to dimensional variations of the base material. It is an object of the present invention to provide a vending machine interior partition plate that can be easily disassembled.

  It is another object of the present invention to provide an interior partition plate for a vending machine that suppresses air intrusion from the fin portion of the vacuum heat insulating plate and hardly deteriorates the heat insulating performance.

An internal partition plate of a vending machine according to the present invention is an internal partition plate of a vending machine for partitioning a product storage with an open front into a plurality of storage chambers, and the internal partition plate has a predetermined shape in advance. A vacuum heat insulating plate formed in the above, a protective sheet member for protecting the surface of the vacuum heat insulating plate facing the storage chamber, and a partition wall attached to the vacuum heat insulating plate at positions corresponding to the ceiling surface, back surface, and bottom surface of the product storage A seal member, and a front frame portion having an L-shaped cross section attached via a filling seal member at a position corresponding to the front opening of the product storage in the vacuum heat insulating plate, and the filling seal member is formed of an elastic member The front frame part is attached to the protective sheet member by a tape-like attachment member that is attached to the protective sheet member and the front frame part .

According to the structure of the above-mentioned partition plate, the partition plate is formed in advance in a vacuum heat insulating plate, protects the surface of the vacuum heat insulating plate with a protective sheet member, and on the upper surface of the product storage of the vacuum heat insulating plate. A partition seal member is formed at a corresponding position, and a filling seal member is provided at a position corresponding to the front opening of the vacuum heat insulating plate, and the filling seal member is formed of an elastic member.

  The inner partition plate thus obtained is dimensional variation of the vacuum heat insulating plate as a base material, the upper surface direction of the product storage is due to the compression degree of the bulkhead seal member, and the front seal direction is the compression of the filling seal member. Since the dimensional variation is absorbed depending on the degree, the entire substrate is formed by the vacuum heat insulating plate. As a result, it has excellent heat insulation and moisture resistance.

  In addition, the protective sheet member is bonded to the surface of the vacuum heat insulating plate as a base material using an adhesive, unlike the conventional case of using the self-adhesive property by foaming of urethane, and based on the protective sheet member. It can be easily peeled off from the vacuum heat insulating plate as a material. This makes it possible to easily disassemble the protective sheet member and the vacuum heat insulating plate serving as the base material during recycling of the internal partition plate.

  In these cases, the filling seal member is preferably formed of a soft foam resin.

  According to this configuration, by using a soft foam resin (soft urethane foam or the like) excellent in heat insulation as the filling seal member, it is possible to ensure the heat insulation required for the internal partition plate, and vacuum insulation. The dimensional variation is absorbed by the degree of compression of the filling seal member in the front direction with respect to the dimensional variation of the plate.

  In the above case, the surface of the protective sheet member is preferably made of resin.

  According to this structure, when the surface is formed of resin as the protective sheet member, it is possible to ensure the moisture resistance required for the internal partition plate. Moreover, since the protective sheet member is formed of resin only on the surface instead of metal, it is possible to reduce the weight of the internal partition plate.

  In addition, since the fin part where the heat-sealed part of the jacket material of the vacuum heat insulating plate protrudes is bent and the protective sheet member is pasted from above, the dimensional variation due to the fin part where the heat-fused part protrudes is reduced. Since the base material is constituted by using the core material of the vacuum heat insulating plate as the outline, the excellent heat insulating performance of the vacuum heat insulating plate is utilized over a wide area, and the base material dimensions are also stabilized.

The internal partition plate of the vending machine of the present invention reduces the heat leakage between the housing chamber, along with highly reliable securing sealing performance between the housing chamber with respect to dimensional variations of the substrate during recycling, etc. In addition, it can be easily decomposed.

The greenhouse 105 can be switched as a cooling or heating chamber by a heat pump cooling cycle.

  Next, the internal partition plates 1a and 1b (hereinafter referred to as the internal partition plate 1) will be described. The internal partition plate 1 is obtained by sandwiching and joining the vacuum heat insulating plate 3 with a bonding material 4 such as a double-sided tape or an adhesive by a vertically long rectangular protective sheet member 2, and a front opening end surface 5 of the protective sheet member 2. A front frame portion 6 is attached so as to cover it, and a filling seal member 7 is embedded between the front frame portion 6 and the vacuum heat insulating plate 3, and is constituted by a packing 8 attached to the front frame portion 6.

  The vacuum heat insulating plate 3 is a core material (heat insulating core material) 3a and the inside is maintained in a vacuum state by drawing a vacuum when the core material 3a is sealed inside the bag-shaped outer covering material 3b. . Since the covering material 3b is large enough to cover and accommodate the core material 3a, the covering material 3b after sealing the core material 3a has a fin-shaped fin portion 3c around the core material 3a. After this fin portion 3c is bent toward the core material 3a side, it is partially fixed by a temporary fixing member 9 such as a tape, and shaped as the outer size of the core material 3a itself, and the base material 1 'of the internal partition plate 1 and To do. At this time, the fin portion 3 c is configured to be bent toward the cooling chamber 103.

  Further, the protective sheet member 2 is provided on the surfaces facing the cooling chamber 103 and the heating chamber 104 (hereinafter, these surfaces are collectively referred to as “front and back surfaces”) when the internal partition plate 1 is attached to the product storage room. As shown in the cross-sectional view taken along the line AA of FIG. 2 in FIG. 3, the base material 2a and the resin sheet 2b are sequentially laminated.

  Since this base material 2a becomes a joint surface when the vacuum insulating plate 3 is sandwiched and joined by the protective sheet member 2 with the joint material 4 such as a double-sided tape or an adhesive, a material having adhesive properties such as paper is used. By using, the protective sheet member 2 and the vacuum heat insulating plate 3 are firmly bonded.

  On the other hand, the resin sheet 2b prevents moisture (water droplets) from entering due to dew condensation on the substrate 2a, thereby preventing deterioration of the substrate 2a and the bonding material 4 due to moisture and destruction of the bonded state, and handling such as assembly. In order to prevent damage to the vacuum heat insulating plate 3 sometimes, when the internal partition plate 1 is mounted in the product storage compartment 102 and separates the cooling chamber 103 and the heating chamber 104, the protective sheet member 2 of the internal partition plate 1 and the vacuum insulation The joined state with the plate 3 is maintained.

  The front frame portion 6 is formed in a substantially L shape with a metal material such as iron or aluminum, for example, and by attaching and joining an attachment member 10 such as a polyester tape over the entire length of the front frame portion 6, for example, The part 6 is attached to the protective sheet member 2 so as to cover the front opening end surface 5 of the protective sheet member 2. A screw hole 6 a is formed in the front end portion of the front frame portion 6, and the packing 8 is attached to the front frame portion 6 with a mounting hole 8 a to be described later of the packing 8.

  Between the front frame portion 6 and the vacuum heat insulating plate 3, the filled sealing member 7 which is formed of, for example, a soft foamed urethane resin over the length of the vacuum heat insulating plate 3 and has heat insulation and elasticity when compressed is compressed by itself. Embed by elasticity.

  When the inner partition plate 1 is attached in the product storage compartment 102 and partitioned into the cooling chamber 103 and the heating chamber 104, the packing 8 is used when the front surface of the product storage compartment 102 is closed by the heat insulating door 122. By abutting the back surface of the heat insulating door 122, the air flow between the cooling chamber 103 and the heating chamber 104 near the front end of the internal partition plate 1a is blocked.

  The packing 8 is made of, for example, an elastic material such as rubber, and the mounting hole 8 a is provided in a mounting portion 8 b formed slightly longer than the front frame portion 6. In addition, when attaching this packing 8 to the front frame part 6, the attachment hole 8a of the packing 8 is matched with the screw hole 6a of the front frame part 6, and it attaches to a screw.

  Here, the manufacturing method of the partition plate 1 in a store | warehouse | chamber is demonstrated. As described above, the vacuum heat insulating plate 3 is bent by the fin portion 3c, and then fixed by the temporary fixing member 9 such as tape, and is molded as the outer size of the core material 3a itself, and then the base material 1 'of the internal partition plate 1 is formed. And

  When the formed vacuum heat insulating plate 3 is used as the base material 1 ′ and the both surfaces are joined to the protective sheet member 2, the back end portion 3 d of the base material 1 ′ is connected to the full length path of the back end face 2 c of the protective sheet material 2. At the same time, it is sandwiched and bonded by a bonding material 4 such as a double-sided tape or adhesive. Here, the surface of the vacuum heat insulating plate 3 obtained by the temporary fixing after the vacuum heat insulating plate 3 formed in advance in a predetermined shape is bent and fixed to the surface of the vacuum heat insulating plate 3 by bending the fin portion 3c of the covering material 3d. The protective sheet member 2 is pasted while covering the fin portion 3c.

  Here, the width dimension d of the protective sheet member 2 and the width dimension d ′ of the molded base material 1 ′ are formed by d> d ′, and at this time, the inner side of the front opening end surface 5 of the protective sheet member 2. The front opening 3e of the vacuum heat insulating plate 3 is located at the top.

  Next, the front inner side 6b of the front frame portion 6 formed in an approximately L shape is protected in accordance with the front opening end surface 5 with the filling seal member 7 in contact with the front opening 3e of the vacuum heat insulating plate 3. With the sheet member 2 covered, the front frame portion 6 is attached to the protective sheet member 2 by attaching and joining an attachment member 10 such as a polyester tape over the entire length of the front frame portion 6. At this time, the filling seal member 7 is embedded by its own compression elasticity between the side facing the front surface of the substrate 1 ′, that is, between the front opening 3 e of the vacuum heat insulating plate 3 and the front inner side 6 b of the front frame portion 6. Yes.

  As a result, the dimensional variation of the core material 3a itself of the vacuum heat insulating plate 3 and the dimensional variation when the fin 3c is bent to form the outer shape of the core material 3a can be changed depending on the degree of compression of the filling seal member 7. The outer size of the core material 3a itself of the vacuum heat insulating plate 3 is obtained.

  And the packing 8 is attached to the front frame part 6, and the partition plate 1 in a warehouse is completed. At this time, the filling seal member 7 is made larger than the dimension under the neck of the screw for attaching the packing 8 to the front frame portion 6 so as to prevent the vacuum heat insulating plate 3 from being damaged.

  When this internal partition plate 1 is mounted in the product storage, the partition seal member 11 having the same width as the thickness of the internal partition plate 1 is attached to the product storage 102 prior to the mounting. A partition wall 130 constituting the ceiling surface, a partition wall 131 constituting the back surface, and a partition wall 119 constituting the bottom surface are attached to a position where the internal partition plate 1 is to be attached in a U-shaped side cross section. And the partition plate 1 is attached in the goods storage 102 via the attachment bracket which is not shown in figure in the state pressed against the partition seal member 11. FIG. Thereby, the inside of the product storage 102 can be divided into two storage chambers, for example, one storage chamber can be used as the cooling chamber 103 and the other storage chamber can be used as the heating chamber 104. As described above, the outer periphery of the vacuum heat insulating material 3 is covered with the filling seal member 7 and the partition wall seal member 11 which are seal members.

  As described above in detail, according to the internal partition plate 1 and the manufacturing method thereof according to the present embodiment, the internal partition plate 1 is formed by pre-forming the vacuum heat insulating plate 3 into a predetermined shape, and the protective sheet member 2 performs vacuum heat insulation. The surface of the plate 3 is protected, the partition seal member 11 is formed at a position corresponding to the upper surface of the product storage of the vacuum heat insulating plate 3, and the filling seal member 7 is formed at a position corresponding to the front opening 3e of the vacuum heat insulating plate 3. The filling seal member 7 is formed of an elastic member. The partition plate 1 thus obtained is dimensional variation of the vacuum heat insulating plate 3 serving as the base material 1 ′, the upper surface direction of the product storage is due to the degree of compression of the partition wall seal member 11, and in the front direction. Since the dimensional variation is absorbed by the degree of compression of the filling seal member 7, the entire base material 1 ′ is formed by the vacuum heat insulating plate 3.

  As a result, it has excellent heat insulation and moisture resistance. Further, in the production of the internal partition plate 1, after the temporary fixing step of temporarily fixing the vacuum heat insulating plate 3 formed in a predetermined shape to the surface of the vacuum heat insulating plate 3 by bending the fin portion 3c of the jacket material, Unlike the conventional method, since the manufacturing process is performed by applying the protective sheet member 2 while covering the fin portion 3c with the surface of the vacuum heat insulating plate 3 obtained by temporary fixing, the work of foaming the heat insulating material at the manufacturing site becomes unnecessary. The internal partition plate 1 can be manufactured efficiently and at low cost. Furthermore, the protective sheet member 2 is protected by bonding to the surface of the vacuum heat insulating plate 3 serving as the base material 1 ′ by using an adhesive, unlike the case of using the self-adhesive property due to foaming of conventional urethane. The sheet member 2 can be easily peeled off from the vacuum heat insulating plate 3 serving as the substrate 1 ′. This makes it possible to easily disassemble the protective sheet member 2 and the vacuum heat insulating plate 3 serving as the base material 1 ′ during recycling of the internal partition plate 1.

  Further, by using a soft foam resin (soft urethane foam or the like) excellent in heat insulation as the filling seal member 7, the heat insulation required for the internal partition plate 1 can be secured and the vacuum heat insulation plate 3 is used. The dimensional variation is absorbed by the degree of compression of the filling seal member 7 in the front direction with respect to the dimensional variation.

  Furthermore, the moisture-proof property requested | required of the partition plate 1 can be ensured by forming the surface as the protection sheet member 2 with resin. Moreover, since the protective sheet member 2 is formed of resin only on the surface instead of metal, the inside partition plate 1 can be reduced in weight.

  Moreover, since the fin part 3c which the heat sealing | fusion part of the jacket material 3b of the vacuum heat insulation board 3 protruded is bent, and the protective sheet member 2 is affixed from it, the dimension variation by the fin part 3c is reduced, and vacuum insulation Since the base material 1 ′ is configured with the core 3 a of the plate 3 as the outer contour, the vacuum heat insulating plate 3 having excellent heat insulating performance can be disposed on almost the entire surface of the internal partition plate 1, so that the inside has high heat insulating performance. The partition plate 1 is obtained, and the substrate dimensions at this time are also stable.

  Further, the detailed configuration of the internal 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.

  In the present invention, in order to simplify the manufacturing process, after the fin portion 3c of the vacuum heat insulating plate 3 is bent toward the core material 3a, it is partially fixed by a temporary fixing member 9 such as a tape and the core material 3a itself. However, the entire fin portion 3c may be fixed.

  Moreover, the internal pressure of the vacuum heat insulating plate 3 increases due to the intrusion of air from the jacket material 3b into the inside, and the heat insulating performance deteriorates. Air intrusion is particularly large from the welded portion where the front and back jacket materials 3b are welded, and the deterioration rate increases as the temperature increases. Therefore, if the fin portion 3c is configured to be bent toward the high-temperature heating chamber 104, the heat insulation performance is likely to deteriorate.

  However, in the present invention, the fin portion 3c of the vacuum heat insulating material 3 is bent toward the cooling chamber 103 side of the commodity storage 102 of the vending machine, so that deterioration of the heat insulating performance can be suppressed and the heat insulating performance can be further improved. Can do.

  Moreover, since the goods storage 102 can be switched between cooling and heating, the deterioration of the heat insulation performance can be suppressed by folding the fin portion 3c toward the cooling greenhouse 104 that has a longer period of use for cooling. Further, in the vending machine constituted by three rooms, the left storage room is dedicated to the cooling room 103, and the cooling room 104 out of the cooling rooms 104 and 105 is cooled from the viewpoint of energy saving. The period of time will be longer. Therefore, in such a vending machine, the inside partition plate 1b can suppress the deterioration of the heat insulating performance by bending the fin portion 3c toward the cooling greenhouse 104.
