INFRARED WELDING DEVICE

To make sure the manufacturing time short while forming a good joint, in the infrared welding equipment that joins three or more liner components by welding.SOLUTION: This is an infrared welding device 10 that continuously joins the components of a liner. It has a collet chuck 20 that holds the domes 3,5 and pipes 4 at intervals and slidably on the same axis, an infrared radiation lamp 30 that heats and melts the ends of the domes 3,5 and pipes 4, a vertical movement mechanism 40 that moves the infrared radiation lamp 30 between an insertion position and an evacuation position, and a pressing mechanism 50 and a pressure receiving mechanism 60 press the ends of the domes 3,5 against each end of the pipe 4. After heating and melting the ends of domes 3,5 and pipes 4 with the infrared radiation lamp 30, the vertical movement mechanism 40 moves the infrared radiation lamp 30 back to the evacuation position, and the pressing mechanism 50 and pressure-receiving mechanism 60 press the ends of each dome 3,5 to the respective ends of pipes 4.SELECTED DRAWING: Figure 3 【課題】３つ以上のライナー構成部材を溶着にて接合する赤外線溶着装置において、良好な接合部を形成しつつ、製造時間の短縮を図る。【解決手段】ライナーの構成部材を連続して接合する赤外線溶着装置１０である。ドーム３，５およびパイプ４を間隔をあけて同軸上に摺動可能に保持するコレットチャック２０と、ドーム３，５およびパイプ４の端部を加熱溶融させる赤外線放射ランプ３０と、赤外線放射ランプ３０を挿入位置と退避位置との間で移動させる上下動作機構４０と、ドーム３，５の端部をパイプ４の各端部に押し付ける押付け機構５０および受圧機構６０と、を備えている。赤外線放射ランプ３０でドーム３，５およびパイプ４の端部を加熱溶融させた後、上下動作機構４０で赤外線放射ランプ３０を退避位置まで退避させ、押付け機構５０および受圧機構６０により各ドーム３，５の端部をパイプ４の各端部に押し付ける。【選択図】図３
