Description
続いて、第一横シール機構7の横シールロールは、内容物が充填された包装袋の開口側を横シールし、これにより、有底筒状の包装袋に充填された内容物は封止されて包装体形態となる。そして、この包装体は直下の第二横シール機構8の横シールロールに送られる。第二横シールロールは、第一横シール機構7によって形成された横シール部分を再度横シールして、その横シール部分の強度をより強固にするための線条シール等を形成する。

前記カム及びカムフォロアは、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、押圧駆動するように制御され、この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で確実に除去されることを特徴とするロールタイプ自動包装機の超音波しごき機構。 - 前記超音波しごき機構は、超音波ホーンを斜め下方に向って設置すると共に、カム及びカムフォロアとバネ部材により押圧駆動された超音波ホーンの先端部分と受け板が横シールロール装置のロール合せ目近傍付近で筒状包装袋を挟み込むように配置されていることを特徴とする請求項3記載のロールタイプ自動包装機の超音波しごき機構。
- 前記超音波しごき機構は、超音波ホーンを斜め下方に向って設置すると共に、カム及びカムフォロアとロータリーアクチュエータにより押圧駆動された超音波ホーンの先端部分と受け板が横シールロール装置のロール合せ目近傍付近で筒状包装袋を挟み込むように配置されていることを特徴とする請求項3記載のロールタイプ自動包装機の超音波しごき機構。
- 前記超音波しごき機構は、自動包装機の動作を停止状態にした場合や、包装フィルム等の装着準備若しくは機器設定状態の確認等のための寸動状態(マニュアル微動状態)にした場合は、超音波ホーンの先端部分と受け板による筒状包装袋の挟み込み動作を強制的に解除することを特徴とする請求項1乃至請求項5いずれかに記載のロールタイプ自動包装機の超音波しごき機構。
