Sheet coating device and sheet coating

Abstract

(57)【要約】 【目的】 枚葉塗工のための塗料供給源としてピストン 型定量ポンプを採用し、しかも、キャビティ、気泡の発 生を伴なうことなくピストン型定量ポンプによる塗料の 吸引速度を高める。 【構成】 塗料タンク1の所定位置に調圧弁1h、リリ ース弁1jを付加して加圧タンク1cを構成し、マイク ロシリンジポンプ2により吸引される塗料に背圧を印加 する。
PURPOSE: To make it possible to set a high suction packing operation speed and to assure the uniformity of a coating film by providing coating material suction routes from a coating material tank to a piston type fixed delivery pump with positive pressure holding means of the coating material. CONSTITUTION: The coating material is sucked by the piston type fixed delivery pump 2 from a coating material tank 1 through a first liquid feed pipeline 1a and a selector valve 2a. The coating material is supplied through a selector valve 2b and a second liquid feed pipeline 3b to a slit 3a for discharging the coating material of a coating material discharging device 3. A material 8 to be coated is attracted and held by a stage 4 and is coated by nearly intersecting the lower prescribed position of the coating material discharging device 3 with the coating material discharge direction. At this time, the routes 1a, 2a from the coating material tank 1 to the piston type fixed delivery pump 2 are provided with the holding means (pressure regulating valves, release valves, etc.) for holding the coating material at a positive pressure. The generation of cavitation and air bubbles is then prevented and the high uniformity of the coating material supply is attained. COPYRIGHT: (C)1996,JPO
