Abstract
【解決手段】被充填物の充填を行った後に袋B内にスチームノズル23を挿入してスチームを噴射し、袋内の空気を置換脱気する縦型袋詰め包装機1。スチーム脱気後に、スチームで加熱された挟圧板27,29で超音波シールを施すシール部を予熱し、シール部全体を均一な温度に予熱する。次いで超音波シール装置35でシール部を超音波シールする。
【選択図】 図1
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。
袋の袋口のシール部を予熱する予熱工程。
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、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るようになっている。
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ようにすることができる。
また、その予熱工程での予熱処理は、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袋口のシール部を挟圧することにより行うことができる。
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、袋の袋口のシール部を超音波シールに先立って所定の予熱温度に予熱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、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シール部を予熱するようにした。
その予熱装置は、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構成することができる。
さらに、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することができる。
予熱装置の他の構成として、互いに向かって所定の距離だけ接離自在な一対の熱板と、その各熱板内に設けられた加熱源としてのヒータを備えて構成し、その熱板は、該熱板が互いに向かって所定の距離だけ移動したときに、袋口のシール部に所定の位置まで接近する放熱部を備えており、袋のシール部を、この放熱部からの輻射熱により予熱することができる。
さらに、超音波シールは袋の袋口の縁部から離れた位置に施され、熱板は、該熱板が互いに向かって所定の距離だけ移動したときに、袋のシール部より上の位置から袋口の縁部までの間で前記袋を挟圧する挟圧部を備えるように構成することができる。
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。
