摘要:
An inkjet printing apparatus (3) carries out printing by moving an inkjet head (19) and printing paper (WP) relative to each other. The inkjet head (19) has a plurality of nozzles for discharging ink droplets. The apparatus (3) includes a feed pipe (25) connected to each nozzle of the inkjet head (19) for feeding ink thereto, an ink feed control valve (27) mounted on the feed pipe (25) for controlling circulation of the ink, a cap (29) for blocking the plurality of nozzles of the inkjet head (19), a decompression device (39) for decompressing an inside of the cap (29), decompression piping (31,35) for connecting the cap (29) and the decompression device (39), a decompression control valve (41) mounted on the decompression piping (35) for controlling communication between the cap (29) and the decompression device (39), and a controller (45). The controller (45) moves the cap (29) into contact with the inkjet head (19) to block all the nozzles of the inkjet head (19), then closes the ink feed control valve (27) and the decompression control valve (39), operates the decompression device (39), thereafter opens the decompression control valve (39) to decompress the inside of the cap (29), opens the ink feed control valve (27), closes the ink feed control valve (27) upon lapse of a predetermined time thereafter, then closes the decompression control valve (41), stops the decompression device (39), and separates the cap (29) from the inkjet head (19).
摘要(中):
喷墨打印设备(3)通过相对于彼此移动喷墨头(19)和打印纸(WP)来进行打印。 喷墨头(19)具有用于排出墨滴的多个喷嘴。 装置(3)包括连接到用于向其供墨的喷墨头(19)的每个喷嘴的进料管(25),安装在进料管(25)上的用于控制油墨循环的供墨控制阀 ,用于阻挡喷墨头(19)的多个喷嘴的盖(29),用于减压盖(29)内部的减压装置(39),用于连接盖(29)的减压管道(31,35) )和减压装置(39),安装在减压管道(35)上用于控制盖(29)和减压装置(39)之间的连通的减压控制阀(41)和控制器(45)。 控制器(45)使帽(29)与喷墨头(19)接触以阻止喷墨头(19)的所有喷嘴,然后关闭供墨控制阀(27)和减压控制阀(39) )操作减压装置(39),然后打开减压控制阀(39)以减压盖(29)的内部,打开供墨控制阀(27),关闭供墨控制阀(27) 然后关闭减压控制阀(41),停止减压装置(39),并将盖(29)与喷墨头(19)分离。
