Abstract
Description
この実施形態の両面塗工システム1の概略構成を図1に示す。両面塗工システム1は、図1に示すように、長尺の基材100をロールツーロール方式で搬送しながら、搬送中の基材100の両面100a,100bに塗工液をそれぞれ塗工した後に乾燥させる一連の処理を連続実行するシステムである。
この実施形態によると、第1エッジ検出器41で検出された活物質層102のエッジの検出位置が基準位置に対してずれたときには、第1移動機構45が駆動されて、基材100がその幅方向に移動することで、第1塗工装置5aにより耐熱保護層103形成用の塗工液が塗工される塗工領域Rの位置が活物質層102に対して所定の範囲内に収められる。また、第2エッジ検出器47で検出された活物質層102のエッジの検出位置が基準位置に対してずれたときには、第2移動機構47が駆動されて、基材100がその幅方向に移動することで、第2塗工装置5bにより耐熱保護層103形成用の塗工液が塗工される塗工領域Rの位置が活物質層102に対して所定の範囲に収められる。したがって、予め形成された各活物質層102に対し優れた位置精度で基材100の両面に耐熱保護層103を形成して品質の良い電池用の電極材を製造することができる。
