Title (EN) INKJET HEAD CLEANING DEVICE AND INKJET HEAD CLEANING METHOD
(FR) DISPOSITIF ET PROCÉDÉ DE NETTOYAGE DE TÊTE À JET D'ENCRE
(JA) インクジェットヘッドの洗浄装置およびインクジェットヘッドの洗浄方法
Abstract:
(EN) Provided are an inkjet head cleaning device and an inkjet head cleaning method, wherein when a large-size inkjet head having a nozzle surface of elongated dimensions is subjected to non-contact cleaning in which the nozzle surface is brought into contact with liquid only, it is possible to ensure high-quality cleaning of the nozzle surface so as not to have any stain or liquid attached or left on any parts surrounding the nozzle. More specifically, this cleaning device 100a for an inkjet head 1 is provided with: a base 3 comprising an upper surface 31 which forms a liquid reservoir space R opposite to a nozzle surface 11 during cleaning thereof, and a plurality of liquid recovery holes 32 which are opened in the upper surface 31 and are aligned along the longitudinal direction of the nozzle surface 11; and recovery facilitating members 4 which are disposed in the liquid recovery holes 32 so as to be exposed out of the upper surface 31. The upper end face 41 of each of the recovery facilitating members 4 protrudes from the upper surface 31 of the base 3, and the amount of protrusion is not uniform among all of the recovery facilitating members 4, so that at least one of the recovery facilitating members 4 protrudes most.
(FR) L'invention concerne un dispositif de nettoyage de tête à jet d'encre et un procédé de nettoyage de tête à jet d'encre, dans lequel, lorsqu'une tête à jet d'encre de grande taille ayant une surface de buse de dimensions allongées est soumise à un nettoyage sans contact, dans lequel la surface de buse est amenée en contact avec uniquement du liquide, il est possible d'assurer un nettoyage de haute qualité de la surface de la buse de manière à ne pas avoir de colorant ni de liquide fixé ou laissé sur n'importe quelle partie entourant la buse. Plus précisément, ce dispositif de nettoyage (100a) pour une tête à jet d'encre (1) est pourvu : d'une base (3) comprenant une surface supérieure (31), qui forme un espace de réservoir de liquide (R) opposé à une surface de buse (11) pendant le nettoyage de celle-ci, et une pluralité de trous de récupération de liquide (32) qui sont ouverts dans la surface supérieure (31) et alignés dans la direction longitudinale de la surface de buse (11) ; d'éléments facilitant la récupération (4) qui sont disposés dans les trous de récupération de liquide (32) de façon à être exposés hors de la surface supérieure (31). La face d'extrémité supérieure (41) de chacun des éléments facilitant la récupération (4) fait saillie sur la surface supérieure (31) de la base (3), et la quantité de saillie n'est pas uniforme parmi tous les éléments facilitant la récupération (4), de telle sorte qu'au moins l'un des éléments facilitant la récupération (4) fait davantage saillie.
(JA) ノズル面の寸法が長大化された大型のインクジェットヘッドに対して、ノズル面に液体のみを接触させる非接触洗浄を行う場合に、ノズル面の周囲にある部分に汚れや液体が付着、残存しないようにして、ノズル面の高品質の洗浄を確実に行うことが可能なインクジェットヘッドの洗浄装置と洗浄方法を提供する。具体的には、このインクジェットヘッド1の洗浄装置100aは、ノズル面11の洗浄時に、ノズル面11と対面して貯液空間Rを形成する上面31と、上面31で開口し、ノズル面11の長手方向に沿って並ぶ複数の液体回収孔32とを含む基台3と、上面31に露出するように複数の液体回収孔32に配置される回収促進部材4とを備える。各回収促進部材4の上端面41は、基台3の上面31から突出しており、その突出量は回収促進部材4全体で一様ではなく、突出量が最大となる回収促進部材4が少なくとも1つ存在する。
