Description

本開示は、熱交換素子に使用される流路板を製造する流路板製造装置及び流路板製造方法に関する。
The present disclosure relates to a flow path plate manufacturing apparatus and a flow path board manufacturing method for manufacturing a flow path plate used for a heat exchange element.

流路板に給気流と排気流を流し熱交換をする熱交換素子として、対向流型熱交換素子がある。対向流型熱交換素子は、例えば、特許文献1に示すように、波形状の断面形状の流路を有する流路板を、交互に積層して形成される。 There is a countercurrent type heat exchange element as a heat exchange element in which a supply air flow and an exhaust flow flow through a flow path plate to exchange heat. As shown in Patent Document 1, for example, the countercurrent type heat exchange element is formed by alternately stacking flow path plates having a flow path having a wave-shaped cross-sectional shape.

流路を流れる給気流又は排気流は、ファンにより送られるが、流路の圧力損失が大きいと、ファンに負荷がかかる。特許文献1に開示された熱交換素子の流路板において、流路の圧力損失を小さくする手段として、例えば、流路板の波形状の山部又は谷部の頂部の一部をなくし、流路の断面積を大きくすることが考えられる。 The supply air flow or the exhaust flow flowing through the flow path is sent by the fan, but if the pressure loss in the flow path is large, the fan is loaded. In the flow path plate of the heat exchange element disclosed in Patent Document 1, as a means for reducing the pressure loss of the flow path, for example, a part of the top of the wavy peak or valley of the flow path plate is eliminated and the flow is performed. It is conceivable to increase the cross-sectional area of the road.

国際公開第2016/147359号International Publication No. 2016/147359

流路の断面積を大きくすることは、完成した流路板の山部又は谷部の頂部の一部を切除する、又は予め孔のあいた流路板を波形に成形することにより実現できるが、これらを実現するための作業は難しく、熟練を要する。 Increasing the cross-sectional area of the flow path can be realized by cutting off a part of the top of the peak or valley of the completed flow path plate, or by forming the flow path plate with holes in advance into a corrugated shape. The work to achieve these is difficult and requires skill.

本開示は、上述のような課題を解決するためになされたもので、流路の圧力損失の小さい流路板を、簡易に製造できる流路板製造装置を提供することを目的とする。 The present disclosure has been made in order to solve the above-mentioned problems, and an object of the present invention is to provide a flow path plate manufacturing apparatus capable of easily manufacturing a flow path plate having a small flow path pressure loss.

上記問題点を解決し、目的を達成するために、本開示に係る流路板製造装置は、帯状の第1の基板を第1の方向に伸びる搬送経路に沿って搬送しながら、熱交換素子に使用される流路板を製造する流路板製造装置であって、互いの回転軸が搬送経路を挟んで平行に且つ搬送経路に垂直に配置され、逆方向に回転する一対のローラと、一対のローラの何れか一方のローラに取付けられ、一方のローラの周面から半径と平行に突出し半径方向から見て矩形状の外形をもつ切断刃と、を備え、一対のローラ間に第1の基板を通過させることにより、切断刃が第1の基板を打ち抜き矩形状の孔を形成する孔形成部と、互いの回転軸が搬送経路を挟んで平行に且つ一対のローラと平行に配置され、互いに噛み合う一対の第1のギアを備え、一対の第1のギア間に孔形成部により孔が形成された第1の基板を通過させて、第1の基板を波形に成形する第1の波形成形部と、一方のローラの回転軸と、一対の第1のギアの何れか一方のギアの回転軸と、を同期して回転させる第1の同期回転部と、第1の波形成形部により波形に成形された第1の基板に、第1の基板とは別に供給される第2の基板を接着して流路板を取得する接着部と、を備える。 In order to solve the above problems and achieve the object, the flow path plate manufacturing apparatus according to the present disclosure is a heat exchange element while transporting a strip-shaped first substrate along a transport path extending in the first direction. A pair of rollers that rotate in the opposite direction, with their rotation axes arranged parallel to each other and perpendicular to the transport path, in a flow path board manufacturing device that manufactures the flow board used in the above. It is equipped with a cutting blade that is attached to one of a pair of rollers, projects parallel to the peripheral surface of one roller in parallel with the radius, and has a rectangular outer shape when viewed from the radial direction, and is provided with a first roller between the pair of rollers. By passing through the substrate, the cutting blade punches out the first substrate to form a rectangular hole, and the rotation axes of each other are arranged parallel to each other and parallel to the pair of rollers. A first substrate comprising a pair of first gears that mesh with each other and passing through a first substrate in which a hole is formed by a hole forming portion between the pair of first gears to form the first substrate into a corrugated shape. A first synchronous rotating portion that synchronously rotates the corrugated forming portion, the rotating shaft of one roller, and the rotating shaft of one of the pair of first gears, and the first corrugated forming portion. The first substrate formed into a corrugated shape is provided with an adhesive portion for adhering a second substrate separately supplied from the first substrate to obtain a flow path plate.

本開示によれば、孔をあける工程と波形に成形する工程を同期させて流路板を製造するので、流路の圧力損失の小さい流路板を、簡易に製造できる流路板製造装置を提供することができる。 According to the present disclosure, since the flow path plate is manufactured by synchronizing the process of making a hole and the process of forming into a corrugated shape, a flow path plate manufacturing apparatus capable of easily manufacturing a flow path plate having a small pressure loss in the flow path is provided. Can be provided.

(実施の形態1)
まず、本開示の実施の形態1に係る流路板製造装置の特徴について、他の流路板との対比において説明する。
(Embodiment 1)
First, the features of the flow path plate manufacturing apparatus according to the first embodiment of the present disclosure will be described in comparison with other flow path plates.

流路板を使用した熱交換素子の一例として、図11に示す熱交換素子8がある。熱交換素子8は、複数の流路板800を上下方向に積層して形成される。各流路板800は、流路を形成する流路形成板801と、流路を仕切る仕切板802とを備える。流路形成板801により区切られた流路、例えば、流路801aには、紙面の背後から前方に向けて流体が流れ、流路801bには、紙面の前方から背後に向けて流体が流れる。流路801aと流路801bに温度の相違する流体が流れることにより、両流体の間で流路形成板801を介して熱交換される。 As an example of the heat exchange element using the flow path plate, there is the heat exchange element 8 shown in FIG. The heat exchange element 8 is formed by stacking a plurality of flow path plates 800 in the vertical direction. Each flow path plate 800 includes a flow path forming plate 801 for forming a flow path and a partition plate 802 for partitioning the flow path. A fluid flows from the back to the front of the paper surface in the flow path separated by the flow path forming plate 801, for example, the flow path 801a, and the fluid flows from the front to the back of the paper surface in the flow path 801b. When fluids having different temperatures flow through the flow path 801a and the flow path 801b, heat is exchanged between the two fluids via the flow path forming plate 801.

ここで、流路形成板801の表面積が大きければ熱交換に寄与する面積が大きくなり、熱交換効率が高まる。このため、熱交換効率の観点からは、流路形成板801の単位体積当たりの山部又は谷部の数が多い方が望ましい。しかし、山部と谷部の数が多くなると、流路の圧力損失が大きくなってしまう。 Here, if the surface area of the flow path forming plate 801 is large, the area contributing to heat exchange becomes large, and the heat exchange efficiency is improved. Therefore, from the viewpoint of heat exchange efficiency, it is desirable that the number of peaks or valleys per unit volume of the flow path forming plate 801 is large. However, as the number of peaks and valleys increases, the pressure loss in the flow path increases.

流路の圧力損失が大きいと、流体を送るファンの負荷が増加する。ファンの負荷が増加することにより、ファンの耐久期間も短くなってしまう。 If the pressure loss in the flow path is large, the load on the fan that sends the fluid increases. As the load on the fan increases, the durability of the fan also shortens.

このような観点から、流路の圧力損失を抑えつつ、熱交換効率が維持した流路板として、図11に示した流路板の山部を一つ置きに配置して圧力損失を小さくした構造の、図12に示す流路板800が考えられる。本実施の形態に係る流路板製造装置は、図12に示す流路板800を製造する装置である。 From this point of view, as a flow path plate in which the heat exchange efficiency is maintained while suppressing the pressure loss of the flow path, every other mountain portion of the flow path plate shown in FIG. 11 is arranged to reduce the pressure loss. The flow path plate 800 of the structure shown in FIG. 12 can be considered. The flow path plate manufacturing apparatus according to the present embodiment is an apparatus for manufacturing the flow path plate 800 shown in FIG.

以下、本実施の形態にかかる流路板製造装置1について、図1~4を参照して説明する。図中、流路形成板11が搬送される方向を左右方向、左右方向に垂直な方向を上下方向と規定する。 Hereinafter, the flow path plate manufacturing apparatus 1 according to the present embodiment will be described with reference to FIGS. 1 to 4. In the figure, the direction in which the flow path forming plate 11 is conveyed is defined as the left-right direction, and the direction perpendicular to the left-right direction is defined as the vertical direction.

図1Aに示すように、流路板製造装置1は、第1の基板である帯状の流路形成板11を供給する流路形成板供給部10と、流路形成板11に孔をあける孔形成部20と、孔があいた流路形成板11を波形に成形する波形成形部30と、波形に成形された流路形成板11に接着剤を塗布する接着剤塗布部40と、孔形成部20のローラの回転軸と波形成形部30のギアの回転軸を同期して回転させる第1の同期回転部50と、波形成形部30の第1のギアの回転軸と接着剤塗布部40のギアの回転軸を同期して回転させる第2の同期回転部60と、帯状の第2の基板である仕切板71を供給する仕切板供給部70と、流路形成板11と仕切板71を接着して流路板本体81を取得する接着ローラ80と、流路板本体81の両側部を切除する切除部90と、を備える。接着剤塗布部40と、仕切板供給部70と、接着ローラ80と、切除部90とが、接着部に相当する。また、接着ローラ80は、流路板本体形成部の一例である。 As shown in FIG. 1A, the flow path plate manufacturing apparatus 1 has a flow path forming plate supply unit 10 for supplying a strip-shaped flow path forming plate 11 which is a first substrate, and a hole for making a hole in the flow path forming plate 11. The forming portion 20, the corrugated forming portion 30 that forms the flow path forming plate 11 having holes into a corrugated shape, the adhesive applying portion 40 that applies an adhesive to the flow path forming plate 11 formed into a corrugated shape, and the hole forming portion. The rotation axis of the roller of 20 and the rotation axis of the gear of the waveform forming unit 30 are rotated in synchronization with each other, and the rotation axis of the first gear of the waveform forming unit 30 and the adhesive application unit 40. A second synchronous rotating portion 60 that synchronously rotates the rotation axis of the gear, a partition plate supply portion 70 that supplies a partition plate 71 that is a strip-shaped second substrate, and a flow path forming plate 11 and a partition plate 71 are provided. It is provided with an adhesive roller 80 for adhering to acquire the flow path plate main body 81, and a cutting portion 90 for cutting both side portions of the flow path plate main body 81. The adhesive application portion 40, the partition plate supply portion 70, the adhesive roller 80, and the cutting portion 90 correspond to the adhesive portion. Further, the adhesive roller 80 is an example of a flow path plate main body forming portion.

流路形成板供給部10、孔形成部20、波形成形部30、接着剤塗布部40、第1の同期回転部50、第2の同期回転部60を、図2A~2Cを用いて説明する。 The flow path forming plate supply section 10, the hole forming section 20, the corrugated forming section 30, the adhesive coating section 40, the first synchronous rotating section 50, and the second synchronous rotating section 60 will be described with reference to FIGS. 2A to 2C. ..

流路形成板供給部10と、孔形成部20と、波形成形部30と、接着剤塗布部40とは、第1の方向Xに伸びる搬送経路に沿ってこの順番に配置され、流路形成板11は、搬送経路に沿って搬送されながら成形されて、仕切板に接着されて流路板となる。 The flow path forming plate supply section 10, the hole forming section 20, the corrugated forming section 30, and the adhesive coating section 40 are arranged in this order along a transport path extending in the first direction X to form a flow path. The plate 11 is formed while being transported along the transport path, and is adhered to the partition plate to form a flow path plate.

流路形成板供給部10は、搬送経路に配置された孔形成部20に流路形成板11を供給する。流路形成板供給部10は、搬送経路と垂直に回転軸が配置されたローラを備え、このローラに巻回された流路形成板11を引き出して、孔形成部20に供給する。流路形成板11は、流路板の素材となるシート状の部材であり、例えば、パルプ素材が使用される。 The flow path forming plate supply unit 10 supplies the flow path forming plate 11 to the hole forming unit 20 arranged in the transport path. The flow path forming plate supply unit 10 includes a roller whose rotation axis is arranged perpendicular to the transport path, and the flow path forming plate 11 wound around the roller is pulled out and supplied to the hole forming unit 20. The flow path forming plate 11 is a sheet-like member that is a material for the flow path plate, and for example, a pulp material is used.

孔形成部20は、流路形成板供給部10により供給された流路形成板11に孔をあける。孔形成部20は、各々の回転軸が搬送経路を挟んで上下に平行に配置される一対のローラ20a、20bを備える。一対のローラ20a、20bの回転軸は、搬送経路と垂直に配置され、互いに逆方向に回転する。 The hole forming portion 20 makes a hole in the flow path forming plate 11 supplied by the flow path forming plate supply portion 10. The hole forming portion 20 includes a pair of rollers 20a and 20b in which each rotation axis is arranged vertically in parallel with the transport path interposed therebetween. The rotation axes of the pair of rollers 20a and 20b are arranged perpendicular to the transport path and rotate in opposite directions.

一対のローラ20a、20bの一方のローラ20bには、外周に切断刃21が取り付けられる。本実施の形態では、下方のローラ20bの外周に沿って、等間隔に8個の切断刃21が取り付けられる。切断刃21の数は8個に限定されない。 A cutting blade 21 is attached to the outer periphery of one of the pair of rollers 20a and 20b. In this embodiment, eight cutting blades 21 are attached at equal intervals along the outer circumference of the lower roller 20b. The number of cutting blades 21 is not limited to eight.

各切断刃21は、図2A、図3及び図4に示すように、ローラ20bの周面から半径方向に突出する。また、各切断刃21は、半径方向から見て、矩形状の外形を備える。矩形形状は、4枚の板状の刃を組み合わせて形成される。他方のローラ20aには、切断刃は取り付けられない。他方のローラ20aの外周面と一方のローラ20bに取り付けられた切断刃21の刃先とは接触して配置される。一対のローラ20a、20bの間を流路形成板11が通過することにより、切断刃21が流路形成板11を打ち抜き、図2A~Cに示すように流路形成板11に矩形状の孔11aが形成される。 As shown in FIGS. 2A, 3 and 4, each cutting blade 21 projects radially from the peripheral surface of the roller 20b. Further, each cutting blade 21 has a rectangular outer shape when viewed from the radial direction. The rectangular shape is formed by combining four plate-shaped blades. A cutting blade cannot be attached to the other roller 20a. The outer peripheral surface of the other roller 20a and the cutting edge of the cutting blade 21 attached to the one roller 20b are arranged in contact with each other. When the flow path forming plate 11 passes between the pair of rollers 20a and 20b, the cutting blade 21 punches out the flow path forming plate 11, and as shown in FIGS. 2A to 2C, the flow path forming plate 11 has a rectangular hole. 11a is formed.

切断刃21を形成する4枚の刃は、図3に示すように、ローラ20bの回転軸方向に伸びて対向し矩形形状の長辺である2辺を形成する刃21a、21bと、ローラ20bの回転軸方向と垂直に伸びて対向し矩形形状の短辺を形成する刃21c、21dと、から形成される。この4つの刃21a~21dにより形成される切断刃21とローラ20aとの間で、流路形成板11を押し切って、流路形成板11に矩形形状の孔11aを形成する。 As shown in FIG. 3, the four blades forming the cutting blade 21 are the blades 21a and 21b extending in the rotation axis direction of the roller 20b and facing each other to form two long sides of a rectangular shape, and the roller 20b. It is formed of blades 21c and 21d that extend perpendicularly to the direction of rotation axis and face each other to form a short side of a rectangular shape. The flow path forming plate 11 is pushed through between the cutting blade 21 formed by the four blades 21a to 21d and the roller 20a to form a rectangular hole 11a in the flow path forming plate 11.

第1の波形成形部である波形成形部30は、孔形成部20により孔があけられた流路形成板11を波形に成形する。図2Aに示すように、波形成形部30は、互いに噛み合う一対の第1のギア30a、30bを備える。一対の第1のギア30a、30bの回転軸は、搬送経路を挟んで上下に平行に配置され、一対のローラ20a、20bの回転軸と平行に配置される。一対の第1のギア30a、30bの歯は、回転軸方向に伸びる。回転する一対の第1のギア30a、30b間を、孔11aが形成された流路形成板11が通過することにより、図2Cに示すように、流路形成板11は、下向きの山部を備える流路形成板11となる。波形成形部30により形成される下向きの山部は、以降の説明において、「下向きの山部」又は単に「山部」と記載する。 The corrugated forming portion 30, which is the first corrugated forming portion, forms the flow path forming plate 11 having holes formed by the hole forming portion 20 into a corrugated shape. As shown in FIG. 2A, the corrugated forming unit 30 includes a pair of first gears 30a and 30b that mesh with each other. The rotation axes of the pair of first gears 30a and 30b are arranged vertically parallel to each other with the transport path interposed therebetween, and are arranged parallel to the rotation axes of the pair of rollers 20a and 20b. The teeth of the pair of first gears 30a and 30b extend in the direction of the axis of rotation. As the flow path forming plate 11 in which the hole 11a is formed passes between the pair of rotating first gears 30a and 30b, the flow path forming plate 11 has a downward mountain portion as shown in FIG. 2C.

Then, the flow path forming plate 11 bent into a corrugated shape is sent to the adhesive application portion 40, and the adhesive is applied to the top of the mountain portion of the flow path forming plate 11.

次に、仕切板供給部70から仕切板71が供給され、仕切板71は、仕切板波形成形部45の一対の第3のギア45a、45bの間を通過して波形に成形される。波形に成形された仕切板71は、接着剤が塗布された流路形成板11が搬送される搬送経路において、流路形成板11の山部の頂部の位置と、仕切板71の山部の頂部の位置が一致する位置に供給される。流路形成板11と仕切板71とは接着ローラ80により接着されて、流路板11cとなる。 Next, the partition plate 71 is supplied from the partition plate supply unit 70, and the partition plate 71 passes between the pair of third gears 45a and 45b of the partition plate corrugated forming unit 45 and is formed into a corrugated shape.

It may be an integral multiple. By setting the number to an integral multiple, one hole 11a corresponds to a mountain portion having an integral multiple, and the interval at which the mountain portion is formed can be increased.

実施の形態1において、切断刃21は、下方のローラ20bに取り付けられ、ローラ20bと、下方の第1のギア30bと、下方に配置された第2のギア40aと、が同期して回転する。しかし、切断刃21の取り付けられたローラと、一対の第1のギア30a、30bと、第2のギア40aが同期して回転すればよく、切断刃21が上方のローラ20aに設けられても、上方の第1のギア30aを同期させてもよい。 In the first embodiment, the cutting blade 21 is attached to the lower roller 20b, and the roller 20b, the lower first gear 30b, and the lower second gear 40a rotate in synchronization with each other. .. However, the roller to which the cutting blade 21 is attached, the pair of first gears 30a and 30b, and the second gear 40a need only rotate in synchronization, and even if the cutting blade 21 is provided on the upper roller 20a. , The upper first gear 30a may be synchronized.

It is not limited to the form. The deflection suppressing portion 12 only needs to be able to support the lower portion of the flow path forming plate 11 conveyed along the conveying path. For example, among the pair of deflection suppressing rollers 12a and 12b shown in FIGS. 5A and 5B, the flow path forming plate Only the deflection suppressing roller 12b that supports the lower portion of 11 may be used.

実施の形態2において、上方から見たたわみ抑制ローラ12aは、孔11aを挟んで一対のローラ12aa、12abを備えると説明したが、たわみ抑制ローラ12aは、このような形態に限定されない。たわみ抑制部12は、流路形成板11の一部を支持できればよく、たわみ抑制ローラ12aの直径が孔11aより大きければ、搬送される流路形成板11の孔11aが通過する位置に設けられてもよい。また、流路形成板11の幅より長い、円柱状のたわみ抑制ローラとしてもよい。 In the second embodiment, it has been described that the deflection suppressing roller 12a viewed from above includes a pair of rollers 12aa and 12ab with the hole 11a interposed therebetween, but the deflection suppressing roller 12a is not limited to such a form. The deflection suppressing portion 12 only needs to be able to support a part of the flow path forming plate 11, and if the diameter of the deflection suppressing roller 12a is larger than the hole 11a, the deflection suppressing portion 12 is provided at a position where the hole 11a of the flow path forming plate 11 to be conveyed passes. You may. Further, a columnar deflection suppressing roller that is longer than the width of the flow path forming plate 11 may be used.
