Abstract

본 발명은 잉크제트 프린터(Ink Jet Printer)에 관한 것으로, 특히 인쇄대기상태나 인쇄가 완료되어 전원이 꺼진 상태에서 인쇄헤드에 잔존하는 잉크가 응고되어 노즐이 막히지 않도록 인쇄헤드를 밀폐시키기 위한 잉크 제트 프린터의 인쇄헤드 캡핑장치(Capping divice)에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ink jet printer, and more particularly, an ink jet for sealing a print head such that the ink remaining in the print head is solidified in the printing standby state or when the printing is completed and the power is turned off so that the nozzle is not clogged. The present invention relates to a printing head capping device for a printer.

본 발명의 잉크제트 프린터의 인쇄헤드 캡핑장치는, 구동모터에 의해 구동되고 가이드 샤프트(16)을 따라 이송되는 인쇄헤드 캐리어(14)가, 인쇄작업을 끝내고 인쇄대기구간으로 수평이동할때, 슬라이더의 브라켓트(66)를 그 운동방향으로 밀어냄으로써 단차형 슬롯트(36)에 의해 안내되는 슬라이더(60)가 상응운동하여, 그 상부에 장착된 러버 캡(71)이 인쇄헤드를 감싸는 동시에, 공기 유통로(73)가 스프링 밸브(50)에 의해 밀봉됨으로써 러버 캡(71)의 내부를 밀폐하게 된다.The print head capping device of the ink jet printer of the present invention is characterized in that the print head carrier 14 driven by the drive motor and conveyed along the guide shaft 16, when the print head carrier 14 finishes the printing operation and moves horizontally to the printing apparatus, By pushing the bracket 66 in the movement direction, the slider 60 guided by the stepped slot 36 correspondingly moves, so that the rubber cap 71 mounted thereon surrounds the print head, The furnace 73 is sealed by the spring valve 50 to seal the inside of the rubber cap 71.

반대로 인쇄명령에 의해 인쇄헤드 캐리어(14)가 인쇄대기구간에서 인쇄구간으로 이동하는 경우에는, 필요시 별도의 제어수단에 의해 진공펌프(90)가 순간적으로 작동하여, 러버 캡(71)내의 공기를 빨아 내어 인쇄헤드 표면에 미량의 잉크가 배출되도록 하는 동시에, 인쇄헤드 캐리어(14)가 제거되어 캐리어(14)에 의해 압압되었던 슬라이더(60)가 인장스프링(80)의 복원력에 의하여 원래 위치로 이동함으로써, 단차형 슬롯트(36)에 의해 안내되는 슬라이더(60)가 하강운동하여 인쇄헤드가 노출되게 되어 그 목적이 달성된다.On the contrary, when the print head carrier 14 is moved from the printing stand to the printing section by a print command, the vacuum pump 90 is momentarily operated by a separate control means if necessary, so that the air in the rubber cap 71 While the printhead carrier 14 is removed and the slider 60 pressed by the carrier 14 is returned to its original position by the restoring force of the tension spring 80. By moving, the slider 60 guided by the stepped slot 36 moves downward to expose the printhead, thereby achieving the object.
