Coating system

Abstract

【課題】間欠塗工塗膜を形成する際に、塗布始め部分と塗布終わり部分での厚みムラを抑制し、塗布面内の膜厚を均一化する。 【解決手段】給液部1と、送液配管部4と、塗工ヘッド部3と、還流配管部4bと、流路切替部2と、送液圧力調整器8と、コントローラ7と、圧力センシング部5と、を備える塗工装置によって間欠塗工塗膜を形成する塗工システムであって、間欠塗工における非塗工時から塗工時へと変化する際、圧力センシング部5で検出した非塗工時と塗工時の圧力差が小さくなるように、コントローラ7により、給液部1、流路切替部2、及び送液圧力調整器8の少なくとも一つをフィードバック制御する。 【選択図】図1
PROBLEM TO BE SOLVED: To uniformalize the thickness within a coated surface by suppressing the uneven thickness in a coating start part and a coating finish part in the formation of intermittently coated coating film.SOLUTION: In a coating system for forming an intermittently coated coating film using a coating apparatus provided with a liquid supply part 1, a liquid sending piping part 4, a coating head part 3, a reflux piping part 4b, a flow passage switching part 2, a liquid-sending pressure adjuster 8, a controller 7 and a pressure sensing part 5, when non-coating time is changed to coating time in the intermittent coating, at least one of the liquid supply part 1, the flow passage switching part 2 and the liquid-sending pressure adjuster 8 is feed-back controlled by the controller 7 so as to reduce the pressure difference between pressure in the non-coating time and pressure in the coating time detected by the pressure sensing part 5.
