Further, the speed reducer 25 provided with the wave gear mechanism is a speed reducer with extremely small backlash. Therefore, the rotational force of the servo motor 26 is transmitted to the roll 13 with vibrations suppressed as much as possible. Is rotated stably without vibration.
- region can be changed arbitrarily,
- the approach angle adjusting device 50 the separator forming mill 60, the pinch roll device 70, the running shear 80, and the edge conveying guide roller 90 as described above. If the separator manufacturing facility is used, the molding material 1A made of a thin metal plate can be accurately formed without lowering the production efficiency, and the highly accurate separator 1 can be efficiently manufactured.

表面に凹部及び凸部が形成された成形領域と、凹部及び凸部が形成されない非成形領域とを円周方向へ交互に有し且つ上下に対向配置された一対のロール間に、前記進入角調節装置によって進入角が調節された被成形材を導入して圧下することにより、前記凹部及び凸部に対応する流路が形成されたセパレータを連続的に成形するセパレータ成形ミルと、
該セパレータ成形ミルで成形されたセパレータの両幅端部を挟持して送り出しつつ張力制御可能なピンチロール装置と、
該ピンチロール装置によって送り出されるセパレータを停止させずにその流路が形成されていない部分において切断する走間シャーと
を備えた固体高分子型燃料電池用セパレータ製造設備。 - 前記セパレータ成形ミルの出側に、セパレータの両幅端部を支持するエッジ搬送ガイドローラを配設した請求項2記載の固体高分子型燃料電池用セパレータ製造設備。
- 前記セパレータ成形ミルが、
前記ロール間のギャップを調節可能なプッシュアップシリンダと、
前記ロールのハウジングと主ベアリング軸箱との間に、上下方向並びに水平方向のガタをなくすよう配設される常時ガタ除去シリンダと、
前記ロールのネック部に嵌着される補助ベアリングと、
該補助ベアリング間に、前記ロールと主ベアリングとの間のガタをなくすよう配設される非成形時ガタ除去シリンダと、
成形荷重を検出する荷重検出器と、
該荷重検出器で検出される成形荷重に基づき、前記プッシュアップシリンダと常時ガタ除去シリンダと非成形時ガタ除去シリンダとにそれぞれ作動信号を出力し、前記ロールのハウジングと主ベアリング軸箱との間のガタの除去を常時行わせつつ、前記非成形領域におけるロールと主ベアリングとの間のガタの除去と、前記成形領域における被成形材の成形とを繰り返し行わせる制御器と
を備えた請求項2又は3記載の固体高分子型燃料電池用セパレータ製造設備。 - 前記各ロールのロール軸部にそれぞれ波動歯車機構を備えた減速機を介して別々のサーボモータを直結すると共に、該減速機をそれぞれ対応する主ベアリング軸箱に直結した請求項4記載の固体高分子型燃料電池用セパレータ製造設備。
