Abstract
Description
例えば、特許文献2には、合成樹脂シートと被積層体とを対向して真空容器内に設置し、大気圧と真空圧との圧力差によって、加熱された合成樹脂シートを被積層体に積層する積層体の製造方法が開示されている。
図6は、本検討例を説明するための説明図であり、本検討例は、フィルム貼着装置101を利用して実施される。
S101において、レンズ11及びフィルム素材13がセットされる。具体的には、まず、蓋22を開けて、レンズ11を容器本体121の底板中央に設置する。次に、フィルム素材13を仕切り壁212の上面に載置し、続いて、蓋22を閉じる(図6(a)参照)。これにより、隣設された第一区画室31と第二区画室32とが、フィルム素材13によって気密に区画される。
レンズ11は、通常、フィルム素材13を貼り着ける面とは反対側の面が凹面12となっているが、第一区画室31内の圧力と第二区画室32内の圧力が等しいとき、変形することはない。
この際、図6(b)に示すように、第一区画室31内の圧力を第二区画室32内の圧力より高くすると、第一区画室31内の圧力と第二区画室32内の圧力との圧力差によって膨れたフィルム素材13が、レンズ11を押圧し、レンズ11が押しつぶされるように弾性変形し、弾性変形したレンズ11の表面にフィルム素材13が貼着される場合がある。
この際、図6(c)に示すように、第一区画室31及び第二区画室32内の圧力を大気圧に戻すと、レンズ11が弾性変形する前の形状に復元するが、フィルム素材13は、弾性変形した状態のレンズ11に合わせて、既に形状が形成されており、上記の復元に追従できずに、レンズ11の外周部において、フィルム素材13が剥離し、貼着不良が発生する場合がある。
また、生産機種を切り換える度に、レンズの凹面形状に対応する受け治具を保管場所から搬送してきて装置に取り付け、生産後には、装置から取り外し、再び保管場所に搬送する必要があり、これらの作業に多くの時間を要し、生産性及び経済性において不利であるという問題もある。
図1は、フィルム貼着装置の一例を示す説明図であり、本実施形態に係る加飾レンズの製造方法は、このようなフィルム貼着装置1を好適に利用して実施することができる。
仕切り板211には、その中央に形成された開口部を覆うように、内側縁部に弾性膜体4が固定されており、また、仕切り壁212には、その上面にフィルム素材13が取り付けられている。そして、仕切り板211の開口部の周縁側と仕切り壁212に囲繞された第二区画室32内には、弾性膜体4の上方に位置した状態でレンズ11が設置されるようになっている。
弾性膜体4は、隣設された第二区画室32と第三区画室33とを気密に区画するとともに、第二区画室32及び第三区画室33内の圧力差によって弾性変形し、レンズ11を支持する機能を有している。この弾性膜体4は、レンズ11が異なる形状の凹面12を有する場合であっても、その異なる形状に対応して弾性変形し、凹面12のほぼ全面を下方から上方に押圧することによってレンズ11を支持する。
なお、弾性膜体4の形状は、上記の機能を実現できる形状であればよく、特に限定されるものではない。例えば、図示してないが、弾性膜体4は、部分的に厚みが異なる形状、又は、凹凸を有する形状であってもよい。
加飾レンズは、貼着材としてのフィルム素材13をレンズ11に貼り着けたものである。本実施形態のレンズ11は、フィルム素材13を貼り着ける面とは反対側の面が凹面12とされる。このレンズ11は、凹面12側が弾性膜体4に対向するように、弾性膜体4を固定する固定部材41上にレンズ11の周縁部を載置させた状態で、第二区画室32内に設置される。
フィルム素材13をレンズ11に接着する接着剤又は粘着剤としては、レンズ11の機能に影響を及ぼすものでなければ、特に限定されない。例えば、レンズ11がプラスチックレンズである場合、レンズ表面を溶かすなどして、その光学的機能を損ねてしまうおそれのある有機溶剤を含まない、反応系、水分散系(ラテックス・エマルジョン系)、ホットメルト系、感圧系の接着剤又は粘着剤を用いるのが好ましく、アクリル樹脂系、エポキシ樹脂系、ウレタン樹脂系、エチレン-酢酸ビニル樹脂系、シアノアクリレート系、塩化ビニル樹脂系、スチレン-ブタジエンゴム系、クロロプレンゴム系などの接着剤又は粘着剤を用いることができる。
以上のようなフィルム貼着装置1を用いた、本実施形態に係る加飾レンズの製造方法においては、例えば、図2のフローチャートに示す各ステップ(S1~S6)が順に行われる。また、図3は、図2の各ステップを説明する断面図である。
なお、隣設された第二区画室32と第三区画室33とは、上述したように、弾性膜体4によって予め気密に区画されている。また、第一区画室31、第二区画室32及び第三区画室33は、各配管311、321、331を介して大気と連通しており、内部の圧力は、大気圧である。
なお、第一区画室31、第二区画室32及び第三区画室33は、ほぼ同時に、かつ、ほぼ同じ圧力に真空引きされる。
なお、フィルム素材13の種類などによっては、常温において、第一区画室31内の圧力と第二区画室32内の圧力との圧力差によって膨れるように変形するものもある。このようなフィルム素材13に対しては、ヒータ221を使用しない場合もある。
したがって、上述した検討例のように、多種多様な形状の受け治具を製作する必要がなくなり、そのための手間やコストも不要となる。さらに、生産機種を切り換える度に、受け治具をセットし直す必要もないので、機種の切り換え作業に要する時間を大幅に短縮することができ、経済性及び生産性を向上させることができる。
また、フィルム素材13をレンズ11に貼り着けるに際し、上昇させる第一区画室31及び第三区画室33内の圧力を等しくするのが好ましい。このようにすると、フィルム素材13によるレンズ11への押圧力と弾性膜体4によるレンズ11への押圧力とがより高いレベルで相殺されるので、レンズ11の変形をより有効に抑制することができる。
図4は、フィルム貼着装置の変形例を示す説明図であり、本変形例に係る加飾レンズの製造方法は、このようなフィルム貼着装置1aを好適に利用して実施することができる。
図4に示すフィルム貼着装置1aは、上述した実施形態のフィルム貼着装置1と比べると、第一区画室31aと第三区画室33aとが連通している点などが相違し、他の構成は、上述した実施形態とほぼ同様としてある。したがって、図4において、図1と同様の構成部分については同一の符号を付して、その詳細な説明を省略する。
なお、各ステップにおいて、上述した実施形態とほぼ同様の内容については、その詳細な説明を省略する。
