Title (EN) INKJET RECORDING APPARATUS AND AIR BUBBLE REMOVAL METHOD
(FR) APPAREIL D’IMPRESSION À JET D’ENCRE ET PROCÉDÉ D’ÉLIMINATION DE BULLES D’AIR
(JA) インクジェット記録装置及び気泡除去方法
Abstract:
(EN) To provide an inkjet recording apparatus for easily and quickly removing an air bubble in an ink flow path, and an air bubble removal method. The inkjet recording apparatus is provided with: a recording head; a first discharge section (2115); a second discharge section (2116); a feeding unit; and a control unit. In the ink flow path of the recording head, there are disposed an ink flow inlet (2111d), a filter (2118) that filters the ink, a first flow outlet (2111e) to the first discharge section for ink on an upstream side of the filter, a second flow outlet (2111f) to the second discharge section for filtered ink on a downstream side, and a shared ink chamber (2111) having a connecting hole (2111c) to a nozzle for the downstream side ink. The control unit determines an ink feeding amount by the feeding unit so that a minimum flow rate of the ink on the upstream side and a minimum flow rate of the ink on the downstream side are simultaneously equal to or more than a predetermined reference rate.
(FR) La présente invention concerne un appareil d’impression à jet d’encre pour éliminer aisément et rapidement une bulle d’air dans un trajet d’écoulement d’encre, et un procédé d’élimination de bulles d’air. L’appareil d’impression à jet d’encre est pourvu de : une tête d’impression ; une première section de décharge (2115) ; une deuxième section de décharge (2116) ; une unité d’alimentation ; et une unité de commande. Dans le trajet d’écoulement d’encre de la tête d’impression sont disposés une entrée d’écoulement d’encre (2111d), un filtre (2118) qui filtre l’encre, une première sortie d’écoulement (2111e) vers la première section de décharge pour l’encre sur un côté amont du filtre, une deuxième sortie d’écoulement (2111f) vers la deuxième section de décharge pour l’encre filtrée sur un côté aval, et une chambre d’encre partagée (2111) comportant un trou de raccordement (2111c) à une buse pour l’encre côté aval. L’unité de commande détermine une quantité d’alimentation d’encre par l’unité d’alimentation de sorte qu’un débit minimal de l’encre sur le côté amont et un débit minimal de l’encre sur le côté aval soient simultanément égaux ou supérieurs à un débit de référence prédéterminé.
(JA) より容易且つ速やかにインク流路内の気泡を除去するインクジェット記録装置及びインク内の気泡除去方法を提供する。インクジェット記録装置は、記録ヘッドと、第1排出部(2115)と、第2排出部(2116)と、送液部と、制御部とを備え、記録ヘッド内のインク流路には、インクの流入口(2111d)、インクをろ過するフィルター(2118)、フィルターの上流側インクの第1排出部への第1流出口(2111e)、ろ過後の下流側インクの第2排出部への第2流出口(2111f)、及び下流側インクのノズルへの連通口(2111c)を有する共通インク室(2111)が設けられ、制御部は、上流側インクの最低流速及び下流側インクの最低流速が同時に所定の基準速度以上となるように送液部によるインク送液量を定める。
