Description

【発明の詳細な説明】 本発明は水平包装機械に関し、特にそのような包装機械
でパッケージを製造するために用いる熱可塑性フィルム
をヒートシールとして切断する装置に関する。
本発明の装置を用い得る包装機械は１９８７年１２月１
５日付けでり［］−フォード等に発行された米国特許筒
４，７１２，３５７号に開示されている。この包装機械
は、長手方向にシールされた熱可塑性材料からなる進行
中のチューブ内に連続的に物品を送り込み、続いて物品
と物品の間でチューブを密封（シール）、切断して個々
の密封パッケージを得るようになっている。
本発明は物品を熱可塑性材料のチューブで包装するため
に用いる改良型の密封切断装置を提供づる。本装置は第
１回転軸線を中心にして回転し得るように取付けられ、
前記第１回転軸線から離隔した位置に滑らかにして弾力
的なアンビル面を具えたアンビル組立体を有する。加熱
ナイフと１対の中空のフィルムクランプを具えたフィル
ム切断組立体が、第１回転軸線に平行する第２回転軸線
を中心にして回転し得るように設けられる、フィルムク
ランプは第２回転軸線に平行するとともに第２回転軸線
からｌ１ｌＩｔ隔して位置する。加熱ナイフがフィルム
クランプ間でフィルムクランプに平行して取付けられる
。フィルム切断組立体とアンビル組立体は各々の軸線を
中心にして同期して回転づるので、フィルムクランプと
加熱ノーイフがアンビル面に押圧され、もってアンビル
面上の熱可塑性材料をすべて密１・１シ切断する。
ばねがフィルムクランプを第２回転軸線から分離するよ
うに偏倚するので、フィルムクランプがアンビル面に圧
接して熱可塑性材料に接触した後にナイフが熱可塑性材
料に接触する。このようにすると熱可塑性材料を確実に
保持した状態でナイフが熱可塑性材料に密封、切断作用
