Description

凹版印刷機Intaglio printing machine
　本発明は、凹版印刷機に関する。 The present invention relates to an intaglio printing press.
　従来の凹版印刷機においては、テーブル上にシート状の基材を配置して印刷するフラットベッドタイプのものとして、配線パターンの溝を形成された平凹版の表面にドクターブレードを接触させインキを供給しつつドクターブレードを平凹版の一端縁側から他端縁側へスライド移動させることにより上記平凹版の溝にインキを充填した後、シリコーンブランケットを外周に巻き付けたブランケット胴を上記平凹版上で転動させて、上記平凹版の溝に充填されたインキをブランケット胴のシリコーンブランケット上に受け渡し、次いで前記フラットベッドの基材上でブランケット胴を転動させ、当該ブランケット胴のシリコーンブランケット上のインキを基材上に転写することにより印刷するものが公知となっている（例えば、下記特許文献１等参照）。 In a conventional intaglio printing machine, as a flat bed type in which a sheet-like base material is arranged and printed on a table, a doctor blade is brought into contact with the surface of a plano-concave plate on which a groove of a wiring pattern is formed to supply ink. While the doctor blade is slid from one end side to the other end side of the flat concave plate while filling the groove of the flat concave plate with ink, the blanket cylinder having the silicone blanket wound around is rolled on the flat concave plate. Transfer the ink filled in the grooves of the flat intaglio plate onto the silicone blanket of the blanket cylinder, and then roll the blanket cylinder over the flatbed substrate to base the ink on the silicone blanket of the blanket cylinder It is known that printing is performed by transferring onto the top (for example, the following patent documents Reference etc.).
特開２０１２－２０９４６５号公報JP 2012-209465 A
　ここで、ドクターブレードで平凹版にインキを供給する場合、供給後、ドクターブレードの先端には付着したインキが残る。この残留インキはそのままにしておくと次回以降のインキ供給の際にインキの粘度調整を困難にしたり、乾燥して落下し異物となるおそれがあるため、定期的に除去することが望ましい。 Here, when the flat blade plate is supplied with ink by the doctor blade, the attached ink remains at the tip of the doctor blade after the ink supply. It is desirable to periodically remove the residual ink because it may make it difficult to adjust the viscosity of the ink at the time of ink supply from the next time onwards, or may be dried and dropped to become foreign matter.
　しかしながら、従来はドクターブレードを平凹版から離したときに作業者が残留インキを適宜拭き取っており、これは作業者の負担になるばかりでなく、拭き取り作業時には印刷機を停止させなければならないことから、作業効率の悪いものとなっていた。 However, conventionally, the operator appropriately wipes off the residual ink when the doctor blade is released from the flat concave plate, which not only burdens the operator but also requires the printer to be stopped at the time of the wiping operation. , Was inefficient work.
　このようなことから本発明は、平凹版にインキを供給するドクターブレードを自動洗浄することで作業者の負担を軽減し、印刷機の稼働効率を向上させることを可能とした凹版印刷機を提供することを目的とする。 Therefore, the present invention provides an intaglio printing machine capable of reducing the burden on the operator by automatically cleaning the doctor blade that supplies the ink to the flat intaglio plate, and improving the operation efficiency of the printing press.
