軸受ユニット、この軸受ユニットを備えたプレス装置及び積層接合体製造装置Bearing unit, press device including this bearing unit, and laminated assembly manufacturing device
本発明は、回転軸を支持する軸受ユニット、この軸受ユニットを備えたプレス装置及び固体高分子型燃料電池用の膜－電極接合体など、膜材料を積層した後に加圧接合してなる積層接合体を製造する積層接合体製造装置に関する。 The present invention relates to a laminated joint formed by laminating membrane materials and then pressurizing them, such as a bearing unit that supports a rotating shaft, a press apparatus equipped with the bearing unit, and a membrane-electrode assembly for a polymer electrolyte fuel cell. The present invention relates to a laminated joined body manufacturing apparatus for manufacturing a body.
従来より、積層接合体を製造するために、膜材料を積層した積層体を加圧ロールを備えたロール式プレス装置等により加圧接合する方法が用いられている。この技術は、近年、固体高分子膜、燃料極膜及び空気極膜を積層、接合してなる固体高分子型燃料電池用の膜－電極接合体（Ｍｅｍｂｒａｎｅ－Ｅｌｅｃｔｒｏｄｅ　Ａｓｓｅｍｂｌｙ：以下、ＭＥＡという）の製造にも用いられている。 2. Description of the Related Art Conventionally, in order to manufacture a laminated joined body, a method in which a laminated body in which film materials are laminated is subjected to pressure bonding with a roll press device or the like equipped with a pressure roll. In recent years, this technology has been developed for a membrane-electrode assembly (hereinafter referred to as MEA) for a polymer electrolyte fuel cell in which a solid polymer membrane, a fuel electrode membrane, and an air electrode membrane are laminated and joined. It is also used for manufacturing.
このような積層接合体を製造するためには、積層体を加熱しながら加圧するために加熱手段を備えた加圧ロールが用いられる場合がある。加熱手段により加圧ロールの温度が上昇すると、その熱が加圧装置の本体に伝達され本体に歪が生じるなどの影響があるため、このような熱伝達の影響を抑制するために、例えば、特許文献１には、軸受部と加圧装置本体との間に冷却手段を備えた熱ロールが提案されている。 In order to manufacture such a laminated joined body, a pressure roll provided with a heating means may be used to pressurize the laminated body while heating. When the temperature of the pressure roll is increased by the heating means, the heat is transmitted to the main body of the pressurizing device, and the main body is distorted.To suppress the influence of such heat transfer, for example, Patent Document 1 proposes a heat roll provided with a cooling means between a bearing portion and a pressurizer main body.
特開２０００－０２７８４８号公報JP 2000-027848 A
しかし、上述の技術では、加圧装置の軸受部近傍の熱伝達を防ぐことはできるが、加圧ロールの温度上昇による軸方向への熱膨張の影響を防ぐことはできない。加圧ロールは、軸受を介して、軸受が組み込まれた軸受ボックスに回動可能に支持されているため、加圧ロールが軸方向に伸長すると、軸受や加圧ロールなどに過大な力が負荷され、加圧装置の加圧精度の低下や構成部材の破損などが生じるという問題があった。
また、加圧ロールを備えたプレス装置により積層接合体を製造する場合には、高精度の加圧が要求されるため、上述の問題がある積層接合体製造装置を積層接合体の製造に好適に用いることができなかった。 However, the above-described technique can prevent heat transfer in the vicinity of the bearing portion of the pressurizing device, but cannot prevent the influence of thermal expansion in the axial direction due to the temperature rise of the pressurizing roll. Since the pressure roll is rotatably supported by the bearing box in which the bearing is incorporated via the bearing, if the pressure roll extends in the axial direction, excessive force is applied to the bearing or the pressure roll. As a result, there is a problem that the pressurization accuracy of the pressurization device is lowered and the structural members are damaged.
In addition, when a laminated assembly is manufactured by a press apparatus equipped with a pressure roll, high-precision pressurization is required, and thus the laminated assembly manufacturing apparatus having the above-mentioned problems is suitable for manufacturing a laminated assembly. Could not be used.
そこで、本発明は、熱膨張に起因して回転軸の転がり軸受や加圧ロールなどに過大な力が負荷されることがなく、プレス装置の加圧精度の低下やプレス装置の構成部材の破損などを防ぐことができる軸受ユニット、この軸受ユニットを備えたプレス装置及び膜材料を積層した後に加圧接合してなる積層接合体を製造する積層接合体製造装置を提供することを目的とする。 Therefore, the present invention does not cause excessive force to be applied to the rolling bearing of the rotating shaft or the pressure roll due to thermal expansion, and the pressurization accuracy of the press device is reduced or the components of the press device are damaged. It is an object of the present invention to provide a bearing unit that can prevent the above, a press device including the bearing unit, and a laminated assembly manufacturing apparatus that manufactures a laminated assembly obtained by pressure bonding after laminating film materials.
本発明では、上記目的を実現するために、第１の発明では、回転軸を回転可能に支持する転がり軸受と、前記転がり軸受を内部に固定した内側ボックスと、前記内側ボックスの外側面に、前記回転軸の軸方向に摺動可能に嵌合させた外側ボックスと、を備える軸受ユニットであって、前記回転軸の伸縮に応じて前記内側ボックスが前記外側ボックスに対して前記回転軸の軸方向に変位する、という技術的手段を用いる。 In the present invention, in order to achieve the above object, in the first invention, a rolling bearing that rotatably supports a rotating shaft, an inner box that fixes the rolling bearing inside, and an outer surface of the inner box, An outer box slidably fitted in the axial direction of the rotating shaft, wherein the inner box is a shaft of the rotating shaft with respect to the outer box according to expansion and contraction of the rotating shaft The technical means of displacement in the direction is used.
第１の発明によれば、回転軸の伸縮を、内側ボックスが外側ボックスに対して軸方向へ変位することにより逃がすことができるので、転がり軸受に過大な力が負荷されることがない。これにより、軸受ユニットは、回転軸を回転可能に良好に支持することができる。 According to the first invention, since the expansion and contraction of the rotating shaft can be released by the inner box being displaced in the axial direction with respect to the outer box, an excessive force is not applied to the rolling bearing. Thereby, the bearing unit can favorably support the rotating shaft in a rotatable manner.
第２の発明では、第１の発明の軸受ユニットにおいて、前記内側ボックスが、熱媒体を流通させることによる冷却手段を備えている、という技術的手段を用いる。 According to a second aspect, in the bearing unit according to the first aspect, the technical means that the inner box includes a cooling means by circulating a heat medium is used.
第２の発明によれば、内側ボックスは熱媒体を流通させることによる冷却手段を備えているので、内側ボックスを冷却することにより、転がり軸受の温度上昇や軸受ユニットにおいて支持する回転軸の径方向への熱膨張など、回転軸において生じた熱に起因する影響を抑制することができる。また、内側ボックスの温度を低く保つことが可能であり、内側ボックスの熱膨張を抑制できることで回転軸の伸縮に応じて内側ボックスが外側ボックスに対して回転軸の軸方向に変位する動きを妨げることがない。 According to the second invention, the inner box is provided with a cooling means by circulating a heat medium. Therefore, by cooling the inner box, the temperature rise of the rolling bearing and the radial direction of the rotating shaft supported by the bearing unit are achieved. It is possible to suppress the influence caused by the heat generated in the rotating shaft such as thermal expansion. Further, the temperature of the inner box can be kept low, and the thermal expansion of the inner box can be suppressed, thereby preventing the inner box from moving in the axial direction of the rotating shaft relative to the outer box according to the expansion and contraction of the rotating shaft. There is nothing.
第３の発明では、第１又は第２の発明の軸受ユニットにおいて、前記回転軸が、被加圧対象を加圧する加圧ロールの回転軸である、という技術的手段を用いる。 According to a third aspect, in the bearing unit according to the first or second aspect, a technical means is used in which the rotation shaft is a rotation shaft of a pressure roll that pressurizes an object to be pressed.
第３の発明によれば、加圧ロールが被加圧対象との摩擦熱によって熱膨張しても、内側ボックスが外側ボックスに対して軸方向へ変位することにより、軸受ユニットが本来の性能を失わない。したがって、この軸受ユニットをプレス装置において使用することによって、プレス装置の加圧精度の低下やプレス装置の構成部材の破損などを防ぐことができる。 According to the third invention, even if the pressure roll is thermally expanded due to frictional heat with the object to be pressed, the inner box is displaced in the axial direction with respect to the outer box, so that the bearing unit has the original performance. I will not lose. Therefore, by using this bearing unit in the press apparatus, it is possible to prevent the pressurization accuracy of the press apparatus from being lowered and the constituent members of the press apparatus from being damaged.
第４の発明では、第３の発明の軸受ユニットにおいて、前記加圧ロールとして加熱手段を備えた加圧ロールを用いる、という技術的手段を用いる。 In 4th invention, the technical means of using the pressurization roll provided with the heating means as said pressurization roll in the bearing unit of 3rd invention is used.
第４の発明によれば、加圧ロールが加熱手段によって著しく熱膨張しても、内側ボックスが外側ボックスに対して軸方向へ変位することにより、軸受ユニットが本来の性能を失わない。したがって、第４の発明において、本発明の効果がさらに有効となり得る。 According to the fourth invention, even if the pressure roll is significantly expanded by the heating means, the inner box is displaced in the axial direction with respect to the outer box, so that the bearing unit does not lose its original performance. Therefore, in the fourth invention, the effect of the present invention can be further effective.
第５の発明では、プレス装置が、被加圧対象を加圧する加圧ロールと、前記加圧ロールを回転駆動する駆動手段と、を備え、前記加圧ロールの回転軸を、少なくとも当該駆動手段から遠い側において第１～第４の発明のいずれかの軸受ユニットにより支持する、という技術的手段を用いる。なお、このプレス装置は、複数の被加圧対象を連続的に加圧する連続プレス装置であってもよい。 In a fifth aspect of the invention, the press device includes a pressure roll that pressurizes the object to be pressed, and a drive unit that rotationally drives the pressure roll, and the rotation shaft of the pressure roll includes at least the drive unit. The technical means of supporting by the bearing unit of any one of the first to fourth inventions on the side far from the center is used. In addition, this press apparatus may be a continuous press apparatus that continuously pressurizes a plurality of objects to be pressed.
第６の発明では、第５の発明のプレス装置が、前記加圧ロールを加熱するための加熱手段をさらに備える、という技術的手段を用いる。 In 6th invention, the technical means that the press apparatus of 5th invention is further equipped with the heating means for heating the said pressurization roll is used.

第５の発明のように、本発明の軸受ユニットは加圧ロールを備えたプレス装置に好適に用いることができる。ここで、一般に駆動手段側が加圧ロールの固定端となるため、加圧ロールの回転軸は、当該駆動手段から遠い側において熱膨張による変位の影響をより大きく受ける。従って、少なくとも当該駆動手段から遠い側において前記回転軸を本発明の軸受ユニットにより支持することにより、加圧ロールの熱膨張の影響をより効果的に防ぐことができる。
また、第６の発明のように、加熱手段による温度上昇が顕著な加熱手段を備えたプレス装置では、より熱膨張の影響が大きくなるので、本発明の軸受ユニットの使用がさらに有効である。
また更に、プレス装置としては、第７及び第８の発明のように、ロール式プレス装置やダブルベルト式プレス装置を用いることができる。 As in the fifth aspect, the bearing unit of the present invention can be suitably used for a press device provided with a pressure roll. Here, since the drive means side is generally the fixed end of the pressure roll, the rotation axis of the pressure roll is more greatly affected by displacement due to thermal expansion on the side far from the drive means. Therefore, by supporting the rotating shaft with the bearing unit of the present invention at least on the side far from the driving means, the influence of thermal expansion of the pressure roll can be prevented more effectively.
Further, as in the sixth aspect of the invention, in the press device provided with the heating means in which the temperature rise by the heating means is remarkable, the influence of the thermal expansion becomes larger, so the use of the bearing unit of the present invention is further effective.

Thereby, the inner side box 13 can be cooled and the influence resulting from the heat transfer from the pressure roll 30, such as the temperature rise of the rolling bearings 11 and 12 and the thermal expansion in the radial direction of the small diameter portion 33b, is suppressed. Can do.
転がり軸受１１、１２を間に挟んで、１組のオイルシール２１、２１が設けられている。第１内カラー１５と第１外カラー１６との間の空間には、外部からオイル配管２３（図４（Ｂ））が接続されており、転がり軸受１１、１２に潤滑用のオイルを供給することができる。 A pair of oil seals 21, 21 are provided with the rolling bearings 11, 12 interposed therebetween. An oil pipe 23 (FIG. 4B) is connected to the space between the first inner collar 15 and the first outer collar 16 from the outside, and supplies lubricating oil to the rolling bearings 11 and 12. be able to.
外側ボックス１４は、内側面１４ａにおいて、内側ボックス１３の外側面１３ａに嵌合されている。内側ボックス１３は、外側ボックス１４に対して回転軸３３の軸方向に摺動可能に嵌合されている。外側ボックス１４は、固定部材５６により装置フレーム２に固定されている。 The outer box 14 is fitted to the outer surface 13a of the inner box 13 on the inner surface 14a. The inner box 13 is fitted to the outer box 14 so as to be slidable in the axial direction of the rotary shaft 33. The outer box 14 is fixed to the apparatus frame 2 by a fixing member 56.
これにより、内側ボックス１３は、固定された外側ボックス１４に対して回転軸３３の軸方向に（加圧ロールの大きさの変化を打ち消すように）移動することができる。ここで、内側ボックス１３は熱媒体を流通させることによる冷却手段を備えているので、内側ボックス１３の温度を低く保つことが可能であり、内側ボックス１３の熱膨張を抑制できることで加圧ロール３０の伸縮に応じて内側ボックス１３が外側ボックス１４に対して軸方向に変位する動きを妨げることがない。 As a result, the inner box 13 can move in the axial direction of the rotary shaft 33 with respect to the fixed outer box 14 (so as to cancel the change in the size of the pressure roll). Here, since the inner box 13 is provided with a cooling means by circulating a heat medium, the temperature of the inner box 13 can be kept low, and the thermal expansion of the inner box 13 can be suppressed, so that the pressure roll 30 The inner box 13 does not hinder the movement of the inner box 13 in the axial direction relative to the outer box 14 in accordance with the expansion and contraction.
図５に示す軸受ユニット４０は、モータ５１に近い方の回転軸３２（小径部３２ｂ）を回動可能に支持している。軸受ユニット４０は、軸受ユニット１０における内側ボックス１３と外側ボックス１４とが分かれておらず、軸受ボックス４１として一体的に形成されている点以外は、軸受ユニット１０と同様の構成である。ここで、軸受ユニット４０は、軸受ユニット１０のように内側ボックス１３と外側ボックス１４とが分かれていないため、軸方向へ移動できない構成となっている。 The bearing unit 40 shown in FIG. 5 rotatably supports the rotating shaft 32 (small diameter portion 32b) closer to the motor 51. The bearing unit 40 has the same configuration as the bearing unit 10 except that the inner box 13 and the outer box 14 in the bearing unit 10 are not separated and are integrally formed as a bearing box 41. Here, since the inner box 13 and the outer box 14 are not separated like the bearing unit 10, the bearing unit 40 is configured to be unable to move in the axial direction.
軸受ユニット１０の動作について説明する。ここでは、加圧ロール３０の温度が上昇し、軸方向に伸長する場合について説明する。 The operation of the bearing unit 10 will be described. Here, the case where the temperature of the pressure roll 30 rises and extends in the axial direction will be described.
図６（Ａ）は、加圧ロール３０が昇温する前の状態である。ヒータ３１ａを使用し、加圧ロール３０の温度が上昇すると、加圧ロール３０は熱膨張により軸方向に伸長する。この伸長量をΔＬとする。 FIG. 6A shows a state before the pressure roll 30 is heated. When the temperature of the pressure roll 30 rises using the heater 31a, the pressure roll 30 extends in the axial direction due to thermal expansion. This extension amount is set to ΔL.
加圧ロール３０が軸方向に伸長する際、図２に示すように回転軸３２の端部はモータ５１に接続され軸方向の移動に関して固定端となるため、加圧ロール３０は図中右方向に伸長しようとする。 When the pressure roll 30 extends in the axial direction, as shown in FIG. 2, the end of the rotary shaft 32 is connected to the motor 51 and becomes a fixed end with respect to the movement in the axial direction. Try to stretch to.
外側ボックス１４は、固定部材５６により装置本体に固定されているため動かないが、内側ボックス１３は外側ボックス１４に対して軸方向に移動可能に構成されているため、加圧ロール３０が伸長すると、図６（Ｂ）に示すように、内側ボックス１３は、加圧ロール３０と一体的に、加圧ロール３０の伸長にあわせて加圧ロール３０の伸長方向（図中右側）にΔＬだけ変位する。 The outer box 14 does not move because it is fixed to the apparatus main body by the fixing member 56, but the inner box 13 is configured to be movable in the axial direction with respect to the outer box 14. As shown in FIG. 6B, the inner box 13 is integrally displaced with the pressure roll 30 by ΔL in the extension direction of the pressure roll 30 (right side in the figure) in accordance with the extension of the pressure roll 30. To do.
このように、加圧ロール３０の伸長を、内側ボックス１３が外側ボックス１４に対して軸方向へ変位することにより逃がすことができるので、転がり軸受１１、１２や加圧ロール３０に過大な力が負荷されることがない。これにより、プレス装置の加圧精度の低下やプレス装置の構成部材の破損などを防ぐことができる。 In this way, the extension of the pressure roll 30 can be released by the inner box 13 being displaced in the axial direction with respect to the outer box 14, so that excessive force is applied to the rolling bearings 11, 12 and the pressure roll 30. There is no load. Thereby, the fall of the pressurization precision of a press apparatus, the failure | damage of the structural member of a press apparatus, etc. can be prevented.
モータ５１から遠い方の回転軸３３の方が加圧ロール３０の熱膨張による変位の影響が大きくなるため、加圧ロール３０の熱膨張の影響をより効果的に防ぐためには、本発明の軸受ユニット１０は、加圧ロール３０の固定端となるモータ５１から、遠い方の回転軸３３を支持することが好ましい。
なお、軸受ユニット４０は、上述のように軸方向へ移動できないが、固定端に近いため、加圧ロール３０の熱膨張に起因する変位量は小さいので、転がり軸受１１、１２や加圧ロール３０に過大な力が生じるおそれがない。 The rotating shaft 33 farther from the motor 51 is more affected by displacement due to thermal expansion of the pressure roll 30. Therefore, in order to more effectively prevent the influence of thermal expansion of the pressure roll 30, the bearing of the present invention. The unit 10 preferably supports the rotary shaft 33 farther from the motor 51 that is the fixed end of the pressure roll 30.
Note that the bearing unit 40 cannot move in the axial direction as described above, but is close to the fixed end, so that the amount of displacement due to the thermal expansion of the pressure roll 30 is small, so the rolling bearings 11 and 12 and the pressure roll 30 There is no risk of excessive force.
このように、軸受ユニット１０は、加熱手段を備えたプレス装置において、熱膨張の影響が大きい加圧ロールに好適に用いることができる。加圧ロール３０が冷却により熱収縮を生じる場合には、内側ボックス１３が外側ボックス１４に対して加圧ロール３０の収縮方向（図中左側）に移動する。これにより、温度上昇時と同様に、転がり軸受１１、１２や加圧ロール３０に過大な力が負荷されることがない。
また、加圧ロール３０を常温で用いる場合においても、ロール式プレス装置１の高速化を図ると、被加圧対象と加圧ロール３０とによる摩擦や転がり軸受１１、１２の摩擦により発生した熱が加圧ロール３０に伝達し温度が上昇するため、軸受ユニット１０を用いることが好ましい。無論、軸受ユニット１０は、熱等の影響により軸方向に変位する回転軸であれば、特に加圧ロールに限らずに用いることができる。 As described above, the bearing unit 10 can be suitably used for a pressure roll having a large influence of thermal expansion in a press apparatus including a heating unit. When the pressure roll 30 is thermally contracted by cooling, the inner box 13 moves in the contraction direction (left side in the figure) of the pressure roll 30 with respect to the outer box 14. Thereby, an excessive force is not applied to the rolling bearings 11 and 12 and the pressure roll 30 as in the case of the temperature rise.
Even when the pressure roll 30 is used at room temperature, if the speed of the roll-type press device 1 is increased, heat generated by friction between the object to be pressed and the pressure roll 30 or friction of the rolling bearings 11 and 12 is generated. Is transmitted to the pressure roll 30 and the temperature rises, so the bearing unit 10 is preferably used. Of course, the bearing unit 10 can be used without being limited to the pressure roll as long as it is a rotating shaft that is displaced in the axial direction due to the influence of heat or the like.

続いて、積層体固定治具１００及び真空ポンプ４を備え積層接合体製造装置として構成されたロール式プレス装置１を用いた積層接合体の製造方法について説明する。ここでは、上流の加圧ロール３０をホットプレスローラ、下流の加圧ロール３０をコールドプレスローラとする。 Then, the manufacturing method of a laminated body using the roll type press apparatus 1 provided with the laminated body fixing jig 100 and the vacuum pump 4 and comprised as a laminated body manufacturing apparatus is demonstrated. Here, the upstream pressure roll 30 is a hot press roller, and the downstream pressure roll 30 is a cold press roller.
まず、収容空間Ｓに積層体Ｗを配置し、真空ポンプ４により収容空間Ｓを排気することにより、第１シート部材１１２及び第２シート部材１２２を収容空間Ｓに配置された積層体Ｗに密着させて積層体Ｗを固定する。 First, the laminated body W is arranged in the accommodation space S, and the accommodation space S is exhausted by the vacuum pump 4 so that the first sheet member 112 and the second sheet member 122 are in close contact with the laminated body W arranged in the accommodation space S. To fix the laminated body W.
次に、ガイドレール７に積層体固定治具１００を載置し、真空ポンプ４による収容空間Ｓの排気を継続しながらガイドレール７に沿って積層体固定治具１００を加圧ロール３０に向かって搬送する。積層体固定治具１００が加圧ロール３０に到達すると、加圧ロール３０により、下流に搬送されながら第１シート部材１１２及び第２シート部材１２２を介して積層体Ｗが加熱され加圧力が負荷される。これにより、積層体Ｗが接合され、積層接合体が製造される。積層体Ｗを加熱しながら加圧することにより、接合強度を向上させることができる。 Next, the laminate fixing jig 100 is placed on the guide rail 7, and the laminate fixing jig 100 is directed toward the pressure roll 30 along the guide rail 7 while continuing to exhaust the housing space S by the vacuum pump 4. Transport. When the laminate fixing jig 100 reaches the pressure roll 30, the laminate W is heated via the first sheet member 112 and the second sheet member 122 while being conveyed downstream by the pressure roll 30, and the applied pressure is loaded. Is done. Thereby, the laminated body W is joined and a laminated joined body is manufactured. By applying pressure while heating the laminated body W, the bonding strength can be improved.
続いて、積層体固定治具１００は下流の加圧ロール３０に搬送され、コールドプレスローラにより積層体Ｗが加圧、冷却されて積層接合体が製造される。これにより、積層体Ｗの冷却を効率的に行い、製造した積層接合体の冷却時間を短縮して迅速に次の工程に送ることができるので、生産性を向上させることができる。 Subsequently, the laminate fixing jig 100 is conveyed to the downstream pressure roll 30, and the laminate W is pressurized and cooled by a cold press roller to produce a laminate joined body. Thereby, since the laminated body W can be cooled efficiently and the cooling time of the produced laminated joined body can be shortened and sent to the next process quickly, productivity can be improved.
上述の製造方法によれば、積層体Ｗを加圧接合して積層接合体を製造するときに、膜材料の位置ずれ、変形、界面の接合欠陥を防止することができるため、積層接合体を、歩留まりよく製造することができる。また、積層体固定治具１００は搬送方向が開放され、一方向に搬送しながら加圧可能に構成されているので、平面プレスなどのバッチ式プレスではなく大量生産に適した連続プレス装置に採用することができ、積層接合体を効率的に製造することができる。そして、上述のように構成された積層接合体製造装置では、高精度の加圧が行うことができるので、積層接合体の製造に好適に用いることができる。 According to the manufacturing method described above, when the laminated body W is pressure-bonded to produce a laminated joint, it is possible to prevent misalignment, deformation, and interface joining defects of the film material. , Can be manufactured with good yield. In addition, since the laminate fixing jig 100 is configured to be pressurized while being transported in one direction and being transported in one direction, it is employed in a continuous press apparatus suitable for mass production rather than a batch press such as a flat press. And a laminated assembly can be efficiently manufactured. And in the laminated joined body manufacturing apparatus comprised as mentioned above, since highly accurate pressurization can be performed, it can be used suitably for manufacture of a laminated joined body.

At the same time, a double belt press device that pressurizes can also be suitably used.

ロール式プレス装置１は、積層接合体製造装置として構成する場合には、加圧ロール３０から見て積層体固定治具１００の搬送方向の上流側に設けられ、積層体固定治具１００と積層体Ｗとを予備加熱する予備加熱部や搬送方向の下流側に設けられ、積層体固定治具１００と積層体Ｗとを冷却する余熱除去部を設けることもできる。これにより、確実な加熱及び冷却が短時間で可能となり、生産性を向上させることができる。 When the roll-type pressing device 1 is configured as a laminated joined body manufacturing device, the roll-type pressing device 1 is provided on the upstream side in the transport direction of the laminated body fixing jig 100 when viewed from the pressure roll 30. A preheating unit that preheats the body W and a remaining heat removal unit that cools the stacked body fixing jig 100 and the stacked body W may be provided on the downstream side in the transport direction.
