Description
前記自動包装機には、前記液状内容物の充填動作の際に、前記筒状包装袋の内側面に付着している内容物を、当該包装袋の外側からしごいて除去するためのしごき機構が、前記横ヒートシールを施すための第一横シール機構の直前に付設されていて、
前記しごき機構は、前記個別包装体の横幅に相当する長さの先端部分を有する超音波ホーンと、この超音波ホーンの先端部分と相対する受け板と、これ等超音波ホーンと受け板、及び、超音波振動を励起するための超音波駆動器を押す若しくは引くように駆動するカムフォロア機構、並びに、ロータリーアクチュエーターと、で構成されると共に、上記超音波ホーンの先端部分と受け板とが、横シールロール装置のロール合わせ目近傍付近にて前記筒状包装袋を挟み込むように設けられ、
且つ、前記しごき機構は、前記超音波ホーン先端部分と受け板の隙間に挟まれている筒状包装袋の横ヒートシール予定部分のみに対して、当該超音波ホーンの先端部分と受け板とが、表裏両側から互いに押圧駆動し合うように制御され、且つ、前記筒状包装袋内の内容物の固形物の含有量が多い場合は、前記ロータリーアクチュエーターの供給エアーの圧力を高く調整するように制御作動せしめることにより、前記超音波ホーンの先端部分と受け板間の押圧力を強くして、上記横ヒートシール予定部分の内部に付着している内容物が、超音波ホーン先端部分から発する超音波振動にて除去されるように構成されていることを特徴としている。

Claims (1)
- 長手方向に二つ折りされながら連続移送されて来る包装フィルムに対して、縦シール機構と第一横シール機構とが、順次縦ヒートシール及び横ヒートシールを施すことにより、上端部分が開口された有底の筒状包装袋をシール形成すると共に、この有底の筒状包装袋内に、細長いパイプ状の充填ノズルを用いて液状内容物を充填し、充填後の前記筒状包装袋の上端開口部分に対して、前記第一横シール機構が横シールを施して、封止された包装体をシール形成する一方、第二横シール機構が、前記第一横シール機構によってシール形成された横ヒートシール形成部分に対して、再度横シールを施して二重に封止された包装体をシール形成し、次いで、この二重に封止された横シール中央付近をカッター装置によって上下方向に切り離すことにより、液状内容物が充填包装された個別包装体を、連続的に作り上げるように構成した自動包装機であって、
前記自動包装機には、前記液状内容物の充填動作の際に、前記筒状包装袋の内側面に付着している内容物を、当該包装袋の外側からしごいて除去するためのしごき機構が、前記横ヒートシールを施すための第一横シール機構の直前に付設されていて、
前記しごき機構は、前記個別包装体の横幅に相当する長さの先端部分を有する超音波ホーンと、この超音波ホーンの先端部分と相対する受け板と、これ等超音波ホーンと受け板、及び、超音波振動を励起するための超音波駆動器を押す若しくは引くように駆動するカムフォロア機構、並びに、ロータリーアクチュエーターと、で構成されると共に、上記超音波ホーンの先端部分と受け板とが、横シールロール装置のロール合わせ目近傍付近にて前記筒状包装袋を挟み込むように設けられ、
且つ、前記しごき機構は、前記超音波ホーン先端部分と受け板の隙間に挟まれている筒状包装袋の横ヒートシール予定部分のみに対して、当該超音波ホーンの先端部分と受け板とが、表裏両側から互いに押圧駆動し合うように制御され、且つ、前記筒状包装袋内の内容物の固形物の含有量が多い場合は、前記ロータリーアクチュエーターの供給エアーの圧力を高く調整するように制御作動せしめることにより、前記超音波ホーンの先端部分と受け板間の押圧力を強くして、上記横ヒートシール予定部分の内部に付着している内容物が、超音波ホーン先端部分から発する超音波振動にて除去されるように構成されていることを特徴とする自動包装機の超音波しごき機構。
