Description

本発明は、自動販売機内の商品収納庫を複数の収納室に仕切る庫内仕切板に関し、特に商品収納庫を冷却室と加温室とに仕切るのに好適な自動販売機の庫内仕切板に関する。 The present invention is related to the internal partition plate for partitioning the vending machine of the commodity storage chamber into a plurality of storage chambers, the internal partition plate suitable vending machines for particular partition the product storage in the cooling chamber and the heating chamber about the.

従来、この種の自動販売機の庫内仕切板として、図４から図６に示すものがある（例えば、特許文献１参照）。   Conventionally, as an internal partition plate of this type of vending machine, there are those shown in FIGS. 4 to 6 (see, for example, Patent Document 1).

図４に示すように、自動販売機２には、内部に商品収納庫３が配置されており、この商品収納庫３は、２枚の庫内仕切板１，１ｘによって左、中央、右の３つの収納室４ａ，４ｂ，４ｃに仕切られており、左収納室４ａは、冷却専用の冷却室として使用される。また、中央および右収納室４ｂ，４ｃは、冷却および加温兼用の兼用室であり、必要に応じて冷却室と加温室に切り換えて使用される。ここでは、中央収納室４ｂが加温室として使用されている場合について説明する。   As shown in FIG. 4, the vending machine 2 has a product storage 3 disposed therein, and the product storage 3 is divided into left, center and right by two internal partition plates 1 and 1x. The left storage chamber 4a is divided into three storage chambers 4a, 4b, and 4c, and is used as a cooling chamber dedicated to cooling. The central and right storage chambers 4b and 4c are dual-purpose chambers for both cooling and heating, and are switched between a cooling chamber and a heating chamber as necessary. Here, a case where the central storage room 4b is used as a heating chamber will be described.

これらの収納室４ａ〜４ｃには、商品コラムがそれぞれ収容されており、これらの商品コラムは、上下方向に商品を収納していると共に、販売時に収納した商品のうち、最下位の商品を販売商品として下方に払い出すようになっている。また、各収納室４の下部には、エバポレータなどを備える冷却装置とヒータが設けられており、さらに、これらによって加温または冷却された空気を商品コラム側に送るファンが設けられている（いずれも図示せず）。   In these storage chambers 4a to 4c, product columns are respectively stored. These product columns store products in the vertical direction, and sell the lowest product among the products stored at the time of sale. The product is paid out downward. In addition, a cooling device including an evaporator and a heater are provided at the lower part of each storage chamber 4, and a fan for sending air heated or cooled by these to the product column side is provided (whichever (Not shown).

図５および図６に示すように、冷却室（左収納室）４ａと加温室（中央収納室）４ｂを仕切っている庫内仕切板１は、上下方向に延びる長方形状のものであり、２枚の側板部（板部）５と、これらの側板部５の周縁部間に設けられた周壁部６とを備えている。これらの側板部５および周壁部６によって画成される枠体１ａの内部空間には、真空断熱板２０が収容され、さらに、真空断熱板２０を包み込むように発泡ポリウレタン（断熱体）１２が充填されている。側板部５および周壁部６はそれぞれ、鋼板を加工することによって製作されており、枠体１ａは、これらを組み合わせ、固定することによって組み立てられている。庫内仕切板１の上縁の周壁部６には、孔６ａが形成されており、この孔６ａは、発泡ポリウレタン１２を充填する際に、注入孔として利用される。   As shown in FIGS. 5 and 6, the internal partition plate 1 that partitions the cooling chamber (left storage chamber) 4a and the heating chamber (central storage chamber) 4b has a rectangular shape extending in the vertical direction. A sheet of side plate portions (plate portions) 5 and a peripheral wall portion 6 provided between the peripheral edge portions of the side plate portions 5 are provided. A vacuum heat insulating plate 20 is accommodated in the internal space of the frame body 1 a defined by the side plate portion 5 and the peripheral wall portion 6, and further filled with polyurethane foam (heat insulating material) 12 so as to enclose the vacuum heat insulating plate 20. Has been. The side plate portion 5 and the peripheral wall portion 6 are each manufactured by processing a steel plate, and the frame body 1a is assembled by combining and fixing them. A hole 6 a is formed in the peripheral wall portion 6 at the upper edge of the internal partition plate 1, and this hole 6 a is used as an injection hole when filling the polyurethane foam 12.

発泡ポリウレタン１２は、庫内仕切板１の製造時に、原料であるジイソシアネート、ポリオールおよび触媒を反応させながら、上記孔６ａを介して注入する（ワンショット成形）ことによって、枠体１ａ内に充填されている。この発泡ポリウレタン１２を枠体１ａ内に充填する際に、発泡ポリウレタン１２が真空断熱板２０の四方の空間に入り込むことによって、発泡ポリウレタン１２の自己接着性によって真空断熱板２０は、枠体１ａ内に固定されている。
特開平１１−１６７６７０号公報 The foamed polyurethane 12 is filled into the frame 1a by injecting it through the holes 6a while reacting the raw materials diisocyanate, polyol and catalyst during the production of the interior partition plate 1 (one-shot molding). ing. When the foamed polyurethane 12 is filled into the frame 1a, the foamed polyurethane 12 enters the four spaces of the vacuum heat insulating plate 20, so that the vacuum heat insulating plate 20 is contained in the frame 1a due to the self-adhesiveness of the foamed polyurethane 12. It is fixed to.
JP-A-11-167670

従来の構成では、断熱体の自己接着性によって真空断熱板と断熱体とが互いに強固に接着する。このため、リサイクル時などにおいて真空断熱板と断熱体との分離分解作業が非常に煩雑となるという問題がある。   In the conventional configuration, the vacuum heat insulating plate and the heat insulating member are firmly bonded to each other due to the self-adhesiveness of the heat insulating member. 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.

また、真空断熱板は芯材（断熱芯材）と、この芯材を袋状の外被材内部に密封する際に真空を引くことによって内部が真空状態に保持されているものである。外被材は芯材を覆って収容するだけの十分な大きさであるため、芯材密封後の外被材には皺折れが生じたり、芯材周囲にヒレ状のヒレ部が生じる。基材全体を真空断熱板とする場合は、このヒレ部を折り曲げて芯材自身を基材寸法としても寸法バラツキが大きく信頼性を確保できないという問題もあった。   The vacuum heat insulating plate is a core material (heat insulating core material), and the inside is kept in a vacuum state by drawing a vacuum when the core material is sealed inside the bag-shaped outer jacket material. 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. In the case where the entire base material is a vacuum heat insulating plate, there is a problem in that reliability is not ensured even if the fin portion is bent to make the core material itself the base material size.

また、商品収納庫内底部に配置した冷却／加熱ユニットから収納庫に吹出した冷気，ないし暖気が収納庫を循環する途上で、仕切板表面を直接洗流するように流れてその壁面に伝熱する。このために、隣接するコールド商品室とホット商品室の間の熱貫流量が大きくなって熱損失が増大する問題があった。   In addition, the cooling air or warm air blown from the cooling / heating unit placed at the bottom of the product storage to the storage circulates in the storage to flow directly to the partition plate surface to transfer heat to the wall surface. To do. For this reason, there has been a problem that the heat flow rate between the adjacent cold product room and the hot product room becomes large and heat loss increases.

さらに、収納した商品を加温する加温室と、商品を冷却する冷却室との間に仕切板を配置した場合には、加温室内の熱によって真空断熱板およびその芯材が暖められ、芯材から水や二酸化炭素ガスなどが発生することがある。これらの水や二酸化炭素ガスなどが発生した場合、真空断熱板内の真空度が低下し、その断熱性が低下することによって、熱リークが発生し、加温室内の温度低下や冷却室内の温度上昇などを招く。これによって、自動販売機の収納庫における冷却効率および加温効率が低下し、消費電力量などのランニングコストが増大するという問題がある。   Furthermore, when a partition plate is placed between the warming room for heating the stored product and the cooling chamber for cooling the product, the vacuum heat insulating plate and its core are heated by the heat in the heating chamber, and the core Water or carbon dioxide gas may be generated from the material. When such water or carbon dioxide gas is generated, the degree of vacuum in the vacuum heat insulating plate is reduced, and the heat insulation is reduced, thereby causing a heat leak, a temperature drop in the heating chamber and a temperature in the cooling chamber. Invite rise. As a result, the cooling efficiency and the heating efficiency in the storage of the vending machine are lowered, and there is a problem that running costs such as power consumption increase.

本発明は、上記従来の課題を解決するもので、冷却室と加温室を仕切るように配備した場合でも収納室間の熱リークを低減し、基材の寸法バラツキに対しても収納室間のシール性を確保した信頼性の高いとともに、隣り合う商品室相互間での伝熱を効果的に減少して熱損失の低減，省エネ化の推進が図れるように改良し、リサイクル時などには、容易に分解することができる自動販売機の庫内仕切板を提供することを目的とする。 The present invention solves the above-described conventional problems, and reduces heat leakage between the storage chambers even when the cooling chamber and the heating chamber are separated from each other. In addition to ensuring high sealing performance, the heat transfer between adjacent product rooms has been effectively reduced to reduce heat loss and promote energy savings. It is an object of the present invention to provide a vending machine interior partition plate that can be easily disassembled.

上記従来の課題を解決するために、本発明の自動販売機の庫内仕切板は、商品を収納する収納庫内を左右に冷却室と加温室に断熱区画する自動販売機の庫内仕切板で、前記冷却室および前記加温室は、複数の商品を上下方向に並んだ状態で収納するとともに、販売時に最下位の商品を販売商品として払い出すように構成されており、前記庫内仕切板は上下方向に延びるとともに、断熱芯材を真空状態に密封した外被材で覆った真空断熱板と、充填発泡された断熱部材と、前記真空断熱板の表面を保護する保護シート部材とで構成し、前記真空断熱板の一面側に前記断熱部材を粘着材で接合し、他面側は前記保護シート部材を粘着材で接合して、内部に空気層が形成されるように前記真空断熱板と前記断熱部材の外周縁部を前記粘着材の粘着層で接合したものである。   In order to solve the above-mentioned conventional problems, the vending machine interior partition plate according to the present invention is a vending machine interior partition plate that insulates the inside of the storage room for storing products into a cooling chamber and a heating chamber. The cooling chamber and the heating chamber are configured to store a plurality of products in a state of being arranged in the vertical direction, and to pay out the lowest product as a sale product at the time of sale. Is composed of a vacuum heat insulating plate that extends in the vertical direction and is covered with a jacket material in which a heat insulating core material is sealed in a vacuum state, a heat insulating member that is filled and foamed, and a protective sheet member that protects the surface of the vacuum heat insulating plate The vacuum heat insulating plate is bonded to the one surface side of the vacuum heat insulating plate with an adhesive material, and the other surface side is bonded to the protective sheet member with an adhesive material so that an air layer is formed therein. And the outer peripheral edge of the heat insulating member to the adhesive layer of the adhesive material It is obtained by joining.

これによって、真空断熱板と断熱部材との間に空気層が形成されて接合されるので熱貫流量を低減することができ加温室と冷却室の間の熱損失を抑制でき、また外周縁部のみ粘着しているのでリサイクル時に真空断熱板と断熱体との分離分解作業を容易に行うことができる。   As a result, an air layer is formed and joined between the vacuum heat insulating plate and the heat insulating member, so that the heat flow rate can be reduced, heat loss between the greenhouse and the cooling chamber can be suppressed, and the outer peripheral edge portion. Since it only adheres, it is possible to easily separate and disassemble the vacuum heat insulating plate and the heat insulator during recycling.

以下、本発明の実施の形態を図面に基づいて説明する。なお、各実施の形態の図中で図４から図６に対応する同一部材には同じ符号を付して、その詳細な説明は省略する。   Hereinafter, embodiments of the present invention will be described with reference to the drawings. In the drawings of the embodiments, the same members corresponding to those in FIGS. 4 to 6 are denoted by the same reference numerals, and detailed description thereof is omitted.

（実施の形態１）
図１および図２は、本発明の一実施形態による自動販売機の庫内仕切板の分解斜視図および組立斜視図をそれぞれ示している。図３は、同実施の形態の自動販売機の庫内仕切板のＡ−Ａ線で切断した断面図である。 (Embodiment 1)
1 and 2 show an exploded perspective view and an assembled perspective view, respectively, of an interior partition plate of a vending machine according to an embodiment of the present invention. FIG. 3 is a cross-sectional view taken along line AA of the internal partition plate of the vending machine according to the embodiment.

庫内仕切板１は、真空断熱板２０の片側面は縦長矩形状の保護シート部材３０が両面粘着性を有する粘着材４０によって挟着接合しており、真空断熱板２０のもう一方の片側面は硬質発泡ポリウレタン１２を材質とする断熱部材５０もまた両面粘着性を有する粘着材４０によって挟着接合されている。   The inside partition plate 1 is formed by sandwiching and joining one side of the vacuum heat insulating plate 20 with a vertically long protective sheet member 30 having a double-sided adhesive material 40, and the other side surface of the vacuum heat insulating plate 20. The heat insulating member 50 made of the hard foamed polyurethane 12 is also sandwiched and bonded by an adhesive material 40 having double-sided adhesive properties.

保護シート部材３０の前面開口端面３１を覆って前枠部６０を取り付け、前枠部６０と真空断熱板２０との間には充填シール部材７０を埋設し、前枠部６０に取り付けられたパッキン８０などにより構成されている。   A front frame portion 60 is attached so as to cover the front opening end surface 31 of the protective sheet member 30, a filling seal member 70 is embedded between the front frame portion 60 and the vacuum heat insulating plate 20, and the packing attached to the front frame portion 60. 80 or the like.

真空断熱板２０は芯材（断熱芯材）２０ａと、この芯材２０ａを袋状の外被材２０ｂ内部に密封する際に真空を引くことによって内部が真空状態に保持されているものである。外被材２０ｂは芯材２０ａを覆って収容するだけの十分な大きさであるため、芯材２０ａ密封後の外被材２０ｂは芯材２０ａ周囲にヒレ状のヒレ部２０ｃが生じる。このヒレ部２０ｃを芯材２０ａ側へ折り曲げた後、部分的にテープ等の仮固定部材９０により固定し、芯材２０ａ自身の外形サイズとして成形して庫内仕切板１の基材１´とする。   The vacuum heat insulating plate 20 has a core (heat insulating core) 20a, and the inside is maintained in a vacuum state by drawing a vacuum when the core 20a is sealed inside the bag-shaped outer cover 20b. . Since the jacket material 20b is large enough to cover and accommodate the core material 20a, the jacket material 20b after sealing the core material 20a has a fin-shaped fin portion 20c around the core material 20a. After bending the fin portion 20c toward the core member 20a, the fin portion 20c is partially fixed by a temporary fixing member 90 such as a tape, and molded as an outer size of the core member 20a itself. To do.

また、保護シート部材３０と断熱部材５０とは、庫内仕切板１を商品収納室に取り付けたときに表面となる面には、シート基材３０ａおよび樹脂シート３０ｂが順に積層されている。   Moreover, the sheet | seat base material 30a and the resin sheet 30b are laminated | stacked in order on the surface used as the surface when the protection partition member 30 and the heat insulation member 50 are attached to the goods storage chamber.

このシート基材３０ａは、保護シート部材３０によって真空断熱板２０を粘着材４０によって挟着接合する際の接合面になったり、また、断熱部材５０を硬質発泡ウレタンスラブで製作する際のウレタンの接合面になるため、例えば紙などの接着性を有する材質を用いることにより、保護シート部材３０と真空断熱板２０とは強固に接合し、硬質発泡ウレタンの接合状態の良いスラブ材から断熱部材５０が製作できる。   This sheet base material 30a becomes a joint surface when the vacuum heat insulating plate 20 is sandwiched and bonded by the adhesive material 40 by the protective sheet member 30, or is made of urethane when the heat insulating member 50 is manufactured by a hard foamed urethane slab. Since it becomes a joint surface, for example, by using a material having adhesiveness such as paper, the protective sheet member 30 and the vacuum heat insulating plate 20 are firmly joined, and the heat insulating member 50 is made of a hard foamed urethane slab material having a good joined state. Can be produced.

一方、樹脂シート３０ｂは、シート基材３０ａへの結露による水分（水滴）の浸入を防止するので、水分によるシート基材３０ａや粘着材４０の劣化および接合状態の破壊を防ぎ、また、組立等の取り扱い時に真空断熱板２０の損傷を防ぐので、庫内仕切板１が商品収納庫内に取り付けられ冷却室と加温室とを仕切る場合、庫内仕切板１の保護シート部材３０と真空断熱板２０との接合状態を維持し、断熱部材５０の硬質発泡ウレタンの接合状態を維持する。   On the other hand, the resin sheet 30b prevents moisture (water droplets) from entering due to dew condensation on the sheet substrate 30a, thereby preventing deterioration of the sheet substrate 30a and the adhesive material 40 due to moisture and destruction of the bonded state, assembling, and the like. In order to prevent damage to the vacuum heat insulating plate 20 during handling, when the internal partition plate 1 is installed in the product storage and separates the cooling chamber from the heated room, the protective sheet member 30 of the internal partition plate 1 and the vacuum heat insulating plate 20 is maintained, and the bonded state of the rigid foamed urethane of the heat insulating member 50 is maintained.

前枠部６０は、例えば鉄やアルミニウムなどの金属材でほぼＬ字状に形成されており、例えばポリエステルテープなどの取付部材１００を前枠部６０の全長にわたって貼り付け接合することにより、前枠部６０を保護シート部材３０の前面開口端面３１を覆って保護シート部材３０に取り付ける。前枠部６０の前端部には、ねじ孔６０ａが形成されており、パッキン８の後述する取付け孔８０ａとでパッキン８０を前枠部６０に取り付ける。   The front frame part 60 is formed in a substantially L shape with a metal material such as iron or aluminum, for example. The part 60 is attached to the protective sheet member 30 so as to cover the front opening end surface 31 of the protective sheet member 30. A screw hole 60 a is formed at the front end portion of the front frame portion 60, and the packing 80 is attached to the front frame portion 60 with an attachment hole 80 a to be described later of the packing 8.

前枠部６０と真空断熱板２０との間には真空断熱板２０の長さにわたって、例えば軟質発泡ウレタン樹脂などで成形されて断熱性と圧縮時に弾性とを有する充填シール部材７０を自身の圧縮弾性により埋設する。   Between the front frame portion 60 and the vacuum heat insulating plate 20, the filled seal member 70 formed by, for example, a soft foamed urethane resin or the like and having heat insulating properties and elasticity at the time of compression is compressed over the length of the vacuum heat insulating plate 20. Embed by elasticity.

パッキン８０は、庫内仕切板１が商品収納庫内に取り付けられ、これを冷却室と加温室に仕切る場合において、商品収納庫の前面が図示しない断熱ドアによって閉鎖されるときに、その断熱ドアの背面に当接することで、庫内仕切板１の前端付近での冷却室および加温室間の空気の流れを遮断するためのものである。   The packing 80 is provided with an insulative door when the inner partition plate 1 is attached to the inside of the product storage, and the front of the product storage is closed by a heat insulating door (not shown) when the partition is divided into a cooling chamber and a greenhouse. 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.

このパッキン８０は、例えばゴムなどの弾性材からなり、取付け孔８０ａが上記前枠部６０よりも若干長く形成された取付部８０ｂに設けられている。なお、このパッキン８０を前枠部６０に取り付ける場合には、前枠部６０のねじ孔６０ａにパッキン８０の取付け孔８０ａを合わせてねじに取り付ける。   The packing 80 is made of, for example, an elastic material such as rubber, and the mounting hole 80 a is provided in a mounting portion 80 b formed slightly longer than the front frame portion 60. In addition, when attaching this packing 80 to the front frame part 60, the attachment hole 80a of the packing 80 is matched with the screw hole 60a of the front frame part 60, and it attaches to a screw.

ここで、庫内仕切板１の製造方法について説明する。上記のように真空断熱板２０はこのヒレ部２０ｃを折り曲げた後、テープ等の仮固定部材９０により固定し、芯材２０ａ自身の外形サイズとして成形して庫内仕切板１の基材１´とする。   Here, the manufacturing method of the partition plate 1 in a store | warehouse | chamber is demonstrated. As described above, the vacuum heat insulating plate 20 is bent by the fin portion 20c and then fixed by a temporary fixing member 90 such as a tape, and is molded as the outer size of the core material 20a itself, and then the base material 1 'of the internal partition plate 1 is formed. And

この成形された真空断熱板２０を基材１´として、保護シート部材３０に接合する際には、保護シート材３０の奥端面３０ｃの全長経路に基材１´の奥端部２０ｄを合わせて粘着材４０のよって挟着接合する。ここで、予め所定形状に成形された真空断熱板２０を外被材２０ｂのヒレ部２０ｃを折り曲げて真空断熱板２０の表面に仮り固定後に、この仮固定によって得られた真空断熱板２０の表面でヒレ部２０ｃを覆いながら保護シート部材３０を貼付ける。   When the molded vacuum heat insulating plate 20 is used as the base material 1 ′ and joined to the protective sheet member 30, the back end portion 20 d of the base material 1 ′ is aligned with the full length path of the back end face 30 c of the protective sheet material 30. The adhesive material 40 is sandwiched and joined. Here, the surface of the vacuum heat insulating plate 20 obtained by this temporary fixing after the vacuum heat insulating plate 20 molded in advance in a predetermined shape is bent on the surface of the vacuum heat insulating plate 20 by bending the fin portion 20c of the jacket material 20b. Then, the protective sheet member 30 is pasted while covering the fin portion 20c.

ここで、保護シート部材３０の幅寸法ｄと成形された基材１´の幅寸法ｄ´とはｄ＞ｄ´にて形成し、この時点では保護シート部材３０の前面開口端面３１よりも内側に真空断熱板２０の前面開口部２０ｅが位置している。   Here, the width dimension d of the protective sheet member 30 and the width dimension d ′ of the molded base material 1 ′ are formed by d> d ′, and at this time, inside the front opening end surface 31 of the protective sheet member 30. The front opening 20e of the vacuum heat insulating plate 20 is located at the top.

次に、真空断熱板２０の前面開口部２０ｅに充填シール部材７０を当接させた状態で、前枠部６０のほぼＬ字状に形成された正面内側６０ｂを前面開口端面３１に合わせて保護シート部材３０を覆った状態で、例えばポリエステルテープなどの取付部材１００を前枠部６０の全長にわたって貼り付け接合することにより、前枠部６０を保護シート部材３０に取り付ける。このとき基材１´の前面に面する側、つまり真空断熱板２０の前面開口部２０ｅと前枠部６０の正面内側６０ｂとの間は、充填シール部材７０が自身の圧縮弾性により埋設している。   Next, in a state where the filling seal member 70 is in contact with the front opening 20 e of the vacuum heat insulating plate 20, the front inner side 60 b formed in a substantially L shape of the front frame 60 is aligned with the front opening end surface 31 and protected. In a state where the sheet member 30 is covered, the front frame portion 60 is attached to the protective sheet member 30 by attaching and joining the attachment member 100 such as a polyester tape over the entire length of the front frame portion 60. At this time, the filling seal member 70 is buried by its own compression elasticity between the side facing the front surface of the substrate 1 ′, that is, between the front opening 20 e of the vacuum heat insulating plate 20 and the front inner side 60 b of the front frame 60. Yes.

これにより、真空断熱板２０の芯材２０ａ自身の寸法バラツキやヒレ部２０ｃを折り曲げて芯材２０ａ自身の外形サイズを成形するときの寸法バラツキに対して、充填シール部材７０の圧縮度合いによって所望の真空断熱板２０の芯材２０ａ自身の外形サイズを得る。   As a result, the dimensional variation of the core material 20a itself of the vacuum heat insulating plate 20 and the dimensional variation when the fin portion 20c is bent to form the outer shape of the core material 20a itself are desired depending on the degree of compression of the filling seal member 70. The outer size of the core material 20a itself of the vacuum heat insulating plate 20 is obtained.

そして、前枠部６０にパッキン８０を取り付けて、庫内仕切板１が完成する。このとき、充填シール部材７０は前枠部６０にパッキン８０を取り付けるねじの首下寸法よりも大きくして真空断熱板２０の損傷を防ぐようにする。   And the packing 80 is attached to the front frame part 60, and the partition plate 1 in a store | warehouse | chamber is completed. At this time, the filling seal member 70 is made larger than the dimension under the neck of the screw for attaching the packing 80 to the front frame portion 60 so as to prevent the vacuum heat insulating plate 20 from being damaged.

この庫内仕切板１を商品収納庫内に取り付ける場合には、その取り付けに先立ち、従来と同様に、庫内仕切板１の厚みとほぼ同じ幅を有する隔壁シール部材１１０を、商品収納庫内の天井面、背面および底面にわたり、庫内仕切板１を取り付けるべき位置に、側断面コ字状に取り付ける。そして、庫内仕切板１を、隔壁シール部材１１０に押し当てた状態で、図示しない取付金具を介して、商品収納庫内に取り付ける。これにより、商品収納庫内を左右２つの収納室に仕切り、例えば、一方の収納室を冷却室として、他方の収納室を加温室として利用することが可能となる。   When attaching the partition plate 1 in the product storage, prior to the mounting, the partition seal member 110 having a width substantially the same as the thickness of the partition plate 1 is attached to the product storage in the same manner as before. At the position where the internal partition plate 1 is to 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 member 110, 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.

以上詳述したように、本実施形態の庫内仕切板１およびその製造方法によれば、庫内仕切板１は真空断熱板２０を予め所定形状に成形し、保護シート部材３０で真空断熱板２０の表面を保護し、真空断熱板２０の商品収納庫の上面に対応する位置に隔壁シール部材１１０を形成させ、真空断熱板２０の前面開口部２０ｅに対応する位置に充填シール部材７０を備えており、充填シール部材７０は弾性部材で形成されている。これにより得られた庫内仕切板１は基材１´となる真空断熱板２０の寸法バラツキに対して、商品収納庫の上面方向は隔壁シール部材１１０の圧縮度により、また、前面方向には充填シール部材７０の圧縮度によって寸法バラツキを吸収するので、基材１´全体を真空断熱板２０にて形成される。   As described above in detail, according to the internal partition plate 1 and the manufacturing method thereof of the present embodiment, the internal partition plate 1 is formed by forming the vacuum heat insulating plate 20 into a predetermined shape in advance, and the protective sheet member 30 is used as the vacuum heat insulating plate. The partition seal member 110 is formed at a position corresponding to the upper surface of the product storage of the vacuum heat insulating plate 20, and the filling seal member 70 is provided at a position corresponding to the front opening 20e of the vacuum heat insulating plate 20. The filling seal member 70 is formed of an elastic member. The partition plate 1 thus obtained is dimensional variation of the vacuum heat insulating plate 20 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 110, and in the front direction. Since the dimensional variation is absorbed by the degree of compression of the filling seal member 70, the entire base material 1 ′ is formed by the vacuum heat insulating plate 20.

その結果、断熱性に優れ、防湿性を有したものになる。また、庫内仕切板１の製造において、予め所定形状に成形された真空断熱板２０を外被材のヒレ部２０ｃを折り曲げて真空断熱板２０の表面に仮り固定する仮固定工程の後に、この仮固定によって得られた真空断熱板２０の表面でヒレ部２０ｃを覆いながら保護シート部材３０を貼付する貼付工程にて製造するので、従来と異なり、製造現場での断熱材発泡作業などが不要となり、庫内仕切板１を効率よく低コストで製造することができる。   As a result, it has excellent heat insulation and moisture resistance. Further, in the manufacture of the internal partition plate 1, after the temporary fixing step of temporarily fixing the vacuum heat insulating plate 20 formed in a predetermined shape to the surface of the vacuum heat insulating plate 20 by bending the fin portion 20 c of the jacket material, Unlike the conventional method, since the manufacturing process is performed by applying the protective sheet member 30 while covering the fin portion 20c with the surface of the vacuum heat insulating plate 20 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.

さらに、保護シート部材３０は基材１´となる真空断熱板２０の表面に粘着材を用いて接合することによって、従来のウレタンの発泡による自己接着性を利用して接着した場合と異なり、保護シート部材３０を基材１´となる真空断熱板２０から容易に剥がすことができる。   Further, the protective sheet member 30 is protected by bonding to the surface of the vacuum heat insulating plate 20 serving as the base material 1 ′ by using an adhesive material, unlike the conventional case of using self-adhesion due to urethane foaming. The sheet member 30 can be easily peeled off from the vacuum heat insulating plate 20 serving as the substrate 1 ′.

これにより、庫内仕切板１のリサイクル時などにおいて、保護シート部材３０と基材１´となる真空断熱板２０との分解作業を容易に行うことが可能となる。   This makes it possible to easily disassemble the protective sheet member 30 and the vacuum heat insulating plate 20 serving as the base material 1 ′ during recycling of the internal partition plate 1.

また、充填シール部材７０として、断熱性に優れた軟質発泡樹脂（軟質ウレタンフォームなど）を用いることにより、庫内仕切板１に要求される断熱性を確保することができるとともに、真空断熱板２０の寸法バラツキに対して前面方向に充填シール部材７０の圧縮度によって寸法バラツキを吸収する。   Further, by using a soft foam resin (soft urethane foam or the like) excellent in heat insulation as the filling seal member 70, the heat insulation required for the internal partition plate 1 can be ensured and the vacuum heat insulation plate 20 is used. The dimensional variation is absorbed by the degree of compression of the filling seal member 70 in the front direction with respect to the dimensional variation.

さらに、保護シート部材３０として表面が樹脂製で形成することにより、庫内仕切板１に要求される防湿性を確保することができる。また金属ではなく表面のみ樹脂で保護シート部材３０を形成するので、庫内仕切板１の軽量化を図る。   Furthermore, the moisture-proof property requested | required of the partition plate 1 can be ensured by forming the surface as a protection sheet member 30 by resin. Moreover, since the protective sheet member 30 is formed of resin only on the surface instead of metal, the internal partition plate 1 is reduced in weight.

また、真空断熱板２０の外被材２０ｂの熱融着部が突出したヒレ部２０ｃを折り曲げて、その上から保護シート部材３０を貼付けるので、ヒレ部２０ｃによる寸法バラツキを低減して真空断熱板２０の芯材２０ａを外形輪郭として基材１´を構成するので、優れた断熱性能を有する真空断熱板２０を庫内仕切板１のほぼ全面に配備できるので高い断熱性能を有した庫内仕切板１となり、このときの基材寸法も安定したものとなる。   Moreover, since the fin part 20c which the heat sealing | fusion part of the jacket material 20b of the vacuum heat insulation board 20 protruded is bent, and the protection sheet member 30 is affixed from it, the dimension variation by the fin part 20c is reduced, and vacuum insulation is carried out. Since the base material 1 ′ is configured with the core material 20 a of the plate 20 as an outer contour, the vacuum heat insulating plate 20 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.

また図３のように、粘着材４０の不織布や軟質発泡樹脂を基材４０ａとして、その両面に粘着性を持たせたものを使用して、庫内仕切板１の表面となる真空断熱板２０の面の外縁に沿って粘着材４０を貼って保護シート部材３０と接合すると、この基材４０ａの厚みによって真空断熱板２０と保護シート部材３０との間は、浮離させて接合している。これによって、商品室内を通風する循環冷気流，ないし暖気流は保護シート部材２０の表面に沿って通風するが、保護シート部材３０を真空断熱板２０から浮いた状態に布設してあるので、両者の間には伝熱性の低い停滞空気層１２０が介在することになるので、薄い保護シート部材３０を布設するだけの簡単な構造で高い断熱性を確保し、庫内仕切板１の断熱材部分への伝熱，熱貫流を抑制して熱損失を効果的に低減できる。   Further, as shown in FIG. 3, the vacuum heat insulating plate 20 that becomes the surface of the internal partition plate 1 using a non-woven fabric of the adhesive material 40 or a soft foamed resin as a base material 40 a and having both surfaces made sticky. When the adhesive material 40 is pasted along the outer edge of the surface and joined to the protective sheet member 30, the vacuum heat insulating plate 20 and the protective sheet member 30 are floated and joined by the thickness of the base material 40a. . As a result, the circulating cold airflow or warm airflow flowing through the commodity room is ventilated along the surface of the protective sheet member 20, but the protective sheet member 30 is laid in a state of floating from the vacuum heat insulating plate 20. Since the stagnation air layer 120 with low heat conductivity is interposed between the two, the heat insulating material portion of the internal partition plate 1 is ensured with a simple structure in which the thin protective sheet member 30 is simply installed. Heat loss and heat flow can be suppressed to effectively reduce heat loss.

さらに、真空断熱板２０の側を加温して使用する頻度が高い庫内と反対側に配備するので、真空断熱板２０側が冷却室に、他方の断熱部材５０側が加温室にそれぞれ面するように配置されているので、真空断熱板２０と加温室の間に断熱部材５０が介在し、さらに真空断熱板２０と冷却室の距離が近くなることによって、真空断熱板２０が加温室の熱気によって加温されにくく、かつ冷却室の冷気によって冷却されやすくなる。   Furthermore, since the side of the vacuum heat insulating plate 20 is heated and disposed on the side opposite to the inside where the frequency of use is high, the vacuum heat insulating plate 20 side faces the cooling chamber, and the other heat insulating member 50 side faces the heating chamber. Since the heat insulating member 50 is interposed between the vacuum heat insulating plate 20 and the heating chamber and the distance between the vacuum heat insulating plate 20 and the cooling chamber is reduced, the vacuum heat insulating plate 20 is heated by the hot air from the heating chamber. It is difficult to be heated and is easily cooled by the cool air in the cooling chamber.

これによって、従来と同じ厚みの庫内仕切板１を用いた場合でも、真空断熱板２０の芯材２０ａから水や２酸化炭素ガスなどが発生しにくくなり、真空断熱板２０の断熱性が低下しなくなることによって、庫内仕切板１の断熱性を向上させることができる。したがって、自動販売機の商品収納庫３における冷却効率および加温効率が向上し、消費電力量などのランニングコストを削減することができる。   As a result, even when the internal partition plate 1 having the same thickness as the conventional one is used, water, carbon dioxide gas, and the like are hardly generated from the core material 20a of the vacuum heat insulating plate 20, and the heat insulating property of the vacuum heat insulating plate 20 is reduced. By not doing so, the heat insulation of the partition plate 1 can be improved. Therefore, the cooling efficiency and the heating efficiency in the product storage 3 of the vending machine are improved, and the running cost such as the power consumption can be reduced.

また、実施形態で示した庫内仕切板１の細部の構成などは、あくまで例示であり、本発明の趣旨の範囲内で適宜、変更することができる。   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.

以上のように、本発明にかかる自動販売機の庫内仕切板は、基材の寸法バラツキに対しても収納室間のシール性を確保できるとともに、リサイクル時などに、容易に分解することができるので、保冷庫などの断熱部材や建材等の断熱パネルにも適用できる。 As described above, the internal partition plate of the vending machine according to the present invention can secure the sealing property between the storage chambers even for the dimensional variation of the base material and can be easily disassembled at the time of recycling or the like. Since it can, it can apply also to heat insulation panels, such as heat insulation members, such as a cool box, and building materials.
