Description
-ライナー-
図1は、本実施形態に係るライナー2を備える高圧タンク1を模式的に示す断面図であり、図2は、ライナー構成部材3,4,5を模式的に示す断面図である。この高圧タンク1は、燃料電池車両に搭載されて、発電用の高圧水素を貯留するものであり、図1に示すように、内殻としての略円筒形状のライナー2と、ライナー2の外周に巻回されて積層されることで外殻を形成するカーボンファイバー6と、ライナー2の両端に圧入で組付けられるアルミ製の口金7,8と、を備えている。
ところで、第1ドーム3と第2ドーム5との間にパイプ4を挟んで軸方向に接合すれば、図1に示すように、接合部2a,2bが2箇所生じることになるが、この場合には、例えば、第1ドーム3の端部3aとパイプ4の一方側(図2の左側)の端部4aとを溶融状態で圧着した後、第2ドーム5の端部5aとパイプ4の他方側(図2の右側)の端部4bとを溶融状態で圧着するといった具合に、2箇所の接合部2a,2bを2回に分けて形成するのが一般的である。もっとも、2箇所の接合部2a,2bを2回に分けて形成する手法では、ライナー2の製造時間の短縮が図り難いという問題がある。
次に、以上のように構成された赤外線溶着装置10を用いた製造プロセスについて説明する。図8~図10は、赤外線溶着装置10を用いた製造プロセスを模式的に説明する図である。
本実施形態は、押付け機構を2つ有している点が、上記実施形態1と異なるものである。以下、実施形態1と異なる点を中心に説明する。
図11は、本実施形態に係る赤外線溶着装置10’を模式的に示す図である。赤外線溶着装置10’は、図11に示すように、基台11、6つのコレットチャック20、2つの赤外線放射ランプ30および2つの上下動作機構40の他、第1押付け機構70と、第2押付け機構80と、を備えている。
赤外線放射ランプ30を用いて第1および第2ドーム3,5並びにパイプ4の端部3a,4a,4b,5aを加熱溶融させ、上下動作機構40により赤外線放射ランプ30を退避位置まで退避させた後、第1および第2押付け機構70,80を同時に作動させる。第1押付け機構70のピストンロッド75aを図11の黒塗り矢印の向きに前進させると、コレットチャック20が第1ドーム3を軸方向に摺動可能に保持していることから、第1ドーム3の口金7に接触している加圧プレート77が、第1ドーム3をパイプ4側に移動させる。同様に、第2押付け機構80のピストンロッド85aを図11の白抜き矢印の向きに前進させると、コレットチャック20が第2ドーム5を軸方向に摺動可能に保持していることから、第2ドーム5の口金8に接触している加圧プレート87が、第2ドーム5を第1ドーム3の移動方向と反対側に移動させる。ピストンロッド75aおよびピストンロッド85aを共に間隔Cと同じストロークだけ前進させると、第1ドーム3の端部3aがパイプ4の端部4aに押し付けられると同時に、第2ドーム5の端部5aがパイプ4の端部4bに押し付けられる。このように、2つの押付け機構70,80を用いることにより、1つの押付け機構50を用いる場合に比して、ストロークを半分にすることができるので、製造時間の短縮をより一層図ることができる。
本実施形態は、パイプ4を軸方向に移動不能に保持する点が、上記実施形態2と異なるものである。以下、実施形態2と異なる点を中心に説明する。
図12は、本実施形態に係る赤外線溶着装置10”を模式的に示す図である。赤外線溶着装置10”は、図12に示すように、基台11、4つのコレットチャック20、2つの赤外線放射ランプ30、2つの上下動作機構40、第1押付け機構70および第2押付け機構80の他、2つのコレットチャック20’を備えている。コレットチャック20’は、パイプ4を軸移動不能に保持するロック機構29を有している。なお、パイプ4を軸方向に移動不能に保持するコレットチャック20’は、図12に示すようなロック機構29を設けなくても、コレットチャック20のリング部27をきつく締め付けることでも実現することができる。本実施形態では、コレットチャック20は、第1および第2ドーム3,5を軸方向に摺動可能に保持している一方、コレットチャック20’は、パイプ4を軸方向に移動不能に保持している。
赤外線放射ランプ30を用いて第1および第2ドーム3,5並びにパイプ4の端部3a,4a,4b,5aを加熱溶融させ、上下動作機構40により赤外線放射ランプ30を退避位置まで退避させた後、第1および第2押付け機構70,80を同時に作動させる。第1押付け機構70のピストンロッド75aを図12の黒塗り矢印の向きに、および、第2押付け機構80のピストンロッド85aを図12の白抜き矢印の向きに、共に間隔Cと同じストロークだけ前進させると、コレットチャック20が第1および第2ドーム3,5を軸方向に摺動可能に保持していることから、第1ドーム3の端部3aがパイプ4の端部4aに押し付けられると同時に、第2ドーム5の端部5aがパイプ4の端部4bに押し付けられる。このように、2つの押付け機構70,80を用いることにより、1つの押付け機構50を用いる場合に比して、ストロークを半分にすることができるので、製造時間の短縮をより一層図ることができる。
本発明は、実施形態に限定されず、その精神又は主要な特徴から逸脱することなく他の色々な形で実施することができる。
