Claims (10)
- シリンダーに固定された下型板と、ピストンに固定された上型板とを互いに接近又は離間するシリンダー機構を有し、これら上型板と下型板に、第1カッターと第2カッターとをそれぞれ保持し、かつ該第1カッターによってレンズの一方側から位置決めを行い、該第2カッターが、該第1カッターの動作に合わせてレンズの他方側から接近して該レンズの切断を行う切断手段を備え、
前記上型板と下型板との間でかつ該下型板上には、第1カッターと第2カッターとがレンズを切断する際に、上型板に接触しかつ該上型板の移動を阻止する位置決め柱が設けられ、この位置決め柱上に弾性部材が設けられていることを特徴とするプラスチックレンズの切断装置。 - 前記切断装置には、前記カッターによる切断に際してレンズを位置決めかつ支持する支持手段をさらに含むことを特徴とする、請求項1に記載のプラスチックレンズの切断装置。
- 前記支持手段に支持されたレンズが、前記カッターの移動方向に対して垂直方向に配置されていることを特徴とする、請求項2に記載のプラスチックレンズの切断装置。
- 前記切断装置には、さらに、前記第1カッターを保持する上型板と、前記第2カッターを保持する下型板とを位置決めし、かつこれら型板の移動をガイドするガイド柱が設けられていることを特徴とする、請求項1に記載のプラスチックレンズの切断装置。
- 前記支持手段には、レンズを支持するためのレンズ支持座が形成された固定板が設けられ、この固定板上のレンズ支持座には、レンズをカッターと直交する方向に固定するための凹溝が形成されていることを特徴とする、請求項3に記載のプラスチックレンズの切断装置。
- 前記レンズ支持座が自在に交換できるように設けられることを特徴とする請求項5に記載のプラスチックレンズの切断装置。
- 前記上型板と下型板とが、第1カッターと第2カッターとが互いに接近する方向に移動する場合、第1カッターが、第2カッターより先に移動し、かつ該第1カッターがレンズの端縁部の切断点に接触して移動の運動を中止することを特徴とする請求項1に記載のプラスチックレンズの切断装置。
- 前記第1カッターがレンズの端縁部の切断点に接触して移動を阻止したとき、該第1カッターを保持する上型板が位置決め柱に当接し、上型板の第1カッターがレンズの端縁部の切断点に接触した後の移動を阻止することを特徴とする請求項7に記載のプラスチックレンズの切断装置。
- 前記弾性部材がバネであることを特徴とする請求項1に記載のラスチックレンズの切断装置。
- 前記第1カッターと第2カッター内に、カッターの温度を調整する電熱線を設けることを特徴とする請求項1に記載のラスチックレンズの切断装置。
