Abstract
Description
しかしながら、特許文献1の装置では、切断した複数のフィルムをそれぞれ異なるガイドローラを使って分離しているので、各フィルムにかかる張力が異なり、切断した後のフィルムの搬送が安定しない虞がある。特に光学フィルムは、薄いフィルムであるので、少しの張力の違いで、フィルムがばたついて安定しない。その結果、幅方向に隣り合う一方のフィルムが他方のフィルムに乗り上げてフィルム同士がくっつく虞がある。
なお、上記の説明で用いた特許文献1、2に記載の部材の符号は、後述する本発明の実施形態で用いる符号と区別するために括弧をつけて表している。
本発明によれば、切断部で不要な縁部を切断した後に、光学フィルム本体及び不要な縁部の双方をニップローラで挟み、その後に不要な縁部を光学フィルム本体から分離する。したがって、不要な縁部の分離をニップローラを通過した後に行うことにより、切断部とニップローラとの間において、不要な縁部の張力と光学フィルム本体の張力とを同じにすることができ、フィルムの搬送を安定させることができる。つまり、ニップローラでテンションカットされるので、ニップローラを通過した後に光学フィルム本体と不要な縁部とが分離されても、切断部とニップローラとの間のフィルムの搬送を安定させることができる。
また、ニップローラを通過した後の光学フィルム本体と不要な縁部とは、それぞれ、所望の方向に案内することができるので、パスラインの設計自由度を向上させることができる。
上記の好ましい構成によれば、光学フィルム本体が駆動側ニップローラ及び従動側ニップローラのうちの一方に掛けられ、不要な縁部が駆動側ニップローラ及び従動側ニップローラのうちの他方に掛けられるので、光学フィルム本体と不要な縁部とを別々の方向に搬送することができ、ニップローラを通過後のパスラインの設計自由度をより向上させやすい。
上記の好ましい構成によれば、光学フィルム本体が駆動側ニップローラに掛けられ、不要な縁部が従動側ニップローラに掛けられるので、光学フィルム本体と不要な縁部とをそれぞれ異なる方向に搬送することができ、ニップローラを通過後のパスラインの設計自由度をより向上させやすい。
上記の好ましい構成によれば、不要な縁部が従動側ニップローラに掛けられ、下方に案内されるので、不要な縁部を自然落下させることができる。その結果、不要な縁部を回収するためのガイドローラ等が不要となり、低コストで不要な縁部を回収できる。
上記の好ましい構成によれば、不要な縁部を光学フィルムの幅方向外側に案内する案内部材を設置するので、不要な縁部を光学フィルムの幅方向外側に切り離して廃棄することができる。したがって、例えばニップローラの下方において光学フィルムが搬送されている場合等であっても、周囲の光学フィルムなどに切り離された不要な縁部が接触することなく、不要な縁部をゴミ箱等に案内することができる。
図2~図4に示すように、ロール状の光学フィルム原反10が原反ローラからフィルム搬送方向に繰り出される。光学フィルムの搬送経路には、切断部100が設けられ、製品に使えない光学フィルムの幅方向両端部における不要な縁部を切断する。
切断部100のフィルム搬送方向下流側に、複数のガイドローラ210、220が設けられている。このガイドローラ210、220により、切断された光学フィルム本体20及び不要な縁部30の双方が、フィルム搬送方向に沿って一対のニップローラ310、320まで案内される。
一対のニップローラ310、320が、ガイドローラ210、220のフィルム搬送方向下流側に設けられている。また、一対のニップローラ310、320は、駆動側ニップローラ310と従動側ニップローラ320とから構成されている。駆動側ニップローラ310は、駆動モータ等で回転駆動されるローラであり、例えば従動側ニップローラ320よりもフィルム搬送方向上流側に配置される。従動側ニップローラ320は、駆動側ニップローラ310に従動して回動するフリーローラであり、駆動側ニップローラ310よりもフィルム搬送方向下流側に配置される。ただし、駆動側ニップローラ310及び従動側ニップローラ320の配置位置は逆でもよいし、駆動側ニップローラと従動側ニップローラとがフィルム搬送方向に直交するように(図4における上下に)配置されてもよい。
一対の案内部材(例えばPPバンド(ポリプロピレンバンド))410、420が、図2に示すように、ニップローラ310、320の下方に位置において、ニップローラ310、320を支持する支持フレーム(図示せず)に設置されている。この一対の案内部材410、420の延びる方向がニップローラ310、320の長手方向(軸方向)と角度を成すように(平行にはならないように)、一対の案内部材410、420は設置されている。好ましくは、一対の案内部材410、420の延びる方向がニップローラ310、320の長手方向に直交するように設置される。案内部材410、420は、それぞれ、ニップローラ310、320の下方に配置され、且つニップローラ310、320の長手方向端部に配置されている。
