Abstract
【解決手段】開閉自在に連結した上部ユニット31B、35Bと下部ユニット31A、35Aに、可撓性チューブTaを載置する載台30とチューブを下方から挟圧する固定クランプ部材62を下部ユニット31A、35Aに配置し、チューブを上方から挟圧する可動クランプ部材63を上部ユニット31B、35Bに配置し、この上部ユニットを下部ユニットにジョイント部材82hで開閉自在に連結する。これと同時に上部ユニットが待機位置から作動位置に閉蓋動作するとき可動クランプ部材を垂直方向に案内する運動規制部材86を設ける。これによって可動クランプ部材は上部ユニットが作動位置から退避位置に開閉する際に作動位置側では載台30に対して垂直方向に移動し退避位置側では回転動する。

Description
互いに開閉自在に連結した上部ユニットと下部ユニットに、可撓性チューブを載置する載台とチューブを下方から挟圧する固定クランプ部材を下部ユニットに配置し、チューブを上方から挟圧する可動クランプ部材を上部ユニットに配置し、この上部ユニットを下部ユニットにジョイント部材で開閉自在に連結する。これと同時に、上部ユニットが待機位置から作動位置に閉蓋動作するとき可動クランプ部材を垂直方向に案内する運動規制部材を設ける。これによって可動クランプ部材は上部ユニットが作動位置から退避位置に開閉する際に作動位置側では載台に対して垂直方向に移動し、退避位置側では回転動することとなる。以下その具体的構成を詳述する。
本発明に係わるチューブ接合装置Aは、複数本(図示のものは2本)の可撓性チューブTa、Tbを載台(処理台;以下同様)30に載置して固定し、このチューブを載台30の処理位置でカットして所定長さに切断処理する。また、処理仕様によってはカットした後、この複数のチューブを、カット面を基準に回転移動又は平行移動して、異なるチューブ同士を接合する。図示の装置は、載台30に第1チューブTaと第2チューブTbを保持固定し、この2本のチューブを同時に加熱ブレード(カッタ手段)50で溶断することによってチューブを所定位置で切断する。そして切断後の第1及び第2チューブTa、Tbを切断面が加熱ブレード50に当接した状態で直線方向に位置移動するか、或いは円方向に旋回移動する。このとき加熱ブレード50は所定温度(チューブの融点温度)に保持し、第1及び第2チューブTa、Tbの位置を反転させて異なるチューブ同士を接合する。
図1に示すように、第1及び第2チューブTa、Tbを切断・接合する載台30は、用途に応じて、例えば作業台形状に構成される。図示のものはテーブル形状に構成した装置フレーム10の天板部に載台30が配置されている。この載台30は、装置フレーム10に固定された固定載台30Bと、装置フレーム10に回動(又は平行移動)可能に取付けられた可動載台30Aで構成されている。このように第1及び第2チューブTa、Tbをセットする載台30を固定載台30Bと可動載台30Aで構成したのはチューブを切断した後、可動載台30Aを180度旋回して第1チューブTaの一端(左端部)と第2チューブTbの一端(右端部)を接合して異なるチューブ同士を連結する為である。
上記可動載台30Aにはチューブを把持して所定姿勢に保持する第1チューブ保持手段41が配置され、固定載台30Bには第2チューブ保持手段46が配置されている。この第1及び第2チューブ保持手段41、46は、後述する加熱ブレード50の位置を挟んでチューブ長手方向に間隔を隔てて配置されている。この処理位置CLに後述するクランプ手段60と加熱ブレード(カッタ手段)50が配置される。
また、第1チューブ保持手段14も、第2チューブ保持手段46と同様、上下グリッパ部材47より加熱ブレード50に近接した左右グリッパ部材48を設けても良い。
前述の載台30には第1チューブ保持手段41と第2チューブ保持手段46の間にカッタ手段(加熱ブレード)50が配置されている。このカッタ手段50は図1にCLで示す切断線に沿って配置され、長手方向前後を第1及び第2チューブ保持手段41,46で保持された可撓性チューブを切断する。図2に示す加熱ブレード50は固定載台30Bの上部ユニット31Bに配置され、扁平薄板形状に構成されている。その構成は既に種々の構造が知られているので図示しないが概略次のように構成される。
前述のように第1チューブ保持手段41と第2チューブ保持手段46とに保持(ホールド)された第1及び第2チューブTa、Tbは、その中央に設定された切断線CLに沿って加熱ブレード50で溶断される。このときチューブの一方が溶液などのタンク(パック)に接続されている場合には切断と同時に内容物が漏れ出す恐れがある。
上述の載台30は図3に従って説明したように、可動載台30Aと、固定載台30Bに分離され、この各載台30は下部ユニット31A、35Aと上部ユニット31B、35Bに分離されている。そして上部ユニット31B、35Bは図3に示すように略々90度開放された開蓋位置と水平状態の閉蓋位置(図1の状態)に開閉自在に構成されている。そのユニット開閉機構については後述する。
前述したように固定載台30Bと可動載台30Aは、それぞれ上部ユニット31B、35Bと、下部ユニット31A、35Aで構成され、上部ユニット31Bと下部ユニット31Aが互いに結合されて固定載台30Bを構成する。また上部ユニット35Bと下部ユニット35Aが互いに結合されて可動載台30Aを構成する。各ユニットの開閉機構について説明する。
