Description
また、特開2004−67177号は、被包装物を充填し、チャンバー内で真空脱気を行い、袋口を仮シールした後に超音波シールを行う真空包装方法及び装置を開示している。この仮シールは、超音波シールのための予熱処理ではなく、袋口を溶着密閉するものであり、超音波シールは、仮にその仮シール部に噛み込みなどによる不具合があっても袋口の密閉を完全にするためにその仮シールの下側に形成されるようになっている。
袋内に被充填物を充填する充填工程。
袋内の空気をスチームで置換して脱気するスチーム脱気工程。
前記袋の袋口のシール部を予熱し、該シール部全体に渡って温度を均一にする予熱工程。
袋口のシール部を超音波シールする超音波シール工程。
そして、その予熱工程はスチーム脱気工程と超音波シール工程との間に設けられ、この予熱工程における予熱処理は、熱源により加熱される互いに接離自在な一対の挟圧部材で前記袋口のシール部を挟圧することにより行い、
その予熱工程において、シール部は、予熱をする前のシール部の最も温度の高い部分の温度以上で、袋の内面側の材料の溶融温度未満の温度に予熱され、その予熱工程における予熱処理は、スチーム脱気工程で使用するスチームの供給源と同じスチーム供給源から供給されるスチームを用いて行われる。
上記課題を解決するために、本発明に係る、吊下げ状態に保持した袋を所定の軌道に沿って移送しながら該袋内に被充填物を充填して包装する縦型袋詰め包装機においては、間欠回転する回転テーブルと、その回転テーブルに周方向所定の間隔で取付けられ、袋を吊下げ状態に保持し、回転テーブルの間欠回転によって所定の停止位置に順次停止させられる複数の保持部材と、回転テーブルの外周に沿って所定の停止位置の1つに配置された、袋内に被充填物を充填する充填装置と、回転テーブルの外周に沿って所定の停止位置の他の1つに配置された、袋内の空気をスチームで置換して脱気するスチーム脱気装置と、回転テーブルの外周に沿って、回転テーブルの回転方向においてスチーム脱気装置が配置された停止位置の次の停止位置に配置された、袋の袋口のシール部を超音波シールする超音波シール装置と、前記袋の袋口のシール部を前記超音波シールに先立って予熱し、前記シール部全体に渡って温度を均一な所定の予熱温度にする予熱装置とを備えている。そして、その予熱装置はスチーム脱気装置と同じ停止位置に配置され、前記袋口のシール部を挟圧する互いに接離自在な一対の挟圧部材と、該挟圧部材を加熱する熱源とを備えている。そして、この予熱装置は、予熱をする前の袋口のシール部の最も温度の高い部分の温度以上で、前記袋の内面側の材料の溶融温度未満の温度になるようにシール部を予熱するようにした。そして、上記各挟圧部材の内部にスチームの流れる流路が形成され、該流路にはスチーム脱気装置で使用されるスチームの供給源と同じ供給源からスチームが供給されるようになっている。
予熱処理を行う際に、スチーム脱気処理で使用するスチームの供給源と同じ供給源からのスチームを使用することにより、別個の予熱するための熱源が不要となる。また、これにより、スチーム脱気でのスチームの温度変更に伴って必要となる予熱温度の変更も同時に行われるので、きわめて好都合である。
予熱部材に挟圧部と放熱部とを設けると、予熱処理と所謂化粧シールとを同時に行うことができ、作業効率が向上する。
