잉크젯 프린터용 헤드의 캡핑 장치{Capping apparatus of ink jet printer head}Capping apparatus of ink jet printer head

본 발명은 잉크젯 프린터에서 헤드를 보호하는 캡핑(Capping) 장치에 관한 것으로서, 보다 상세하게는 잉크젯 프린터에서 헤드를 사용하지 않을 때 노즐을 보호할 수 있도록 설치된 잉크젯 프린터용 헤드의 캡핑 장치에 관한 것이다.The present invention relates to a capping apparatus for protecting a head in an inkjet printer, and more particularly, to a capping apparatus for an inkjet printer head installed to protect a nozzle when the head is not used in an inkjet printer.

일반적으로, 잉크젯 프린터는 피코리터급의 잉크 방울을 열전사등의 방법을 통해 종이에 분사함으로써, 텍스트 및 화상을 출력하는 장치인 바, 상기한 잉크 방울을 분사하기 위해 매우 미세하게 작동하는 헤드가 필요하게 된다.In general, an inkjet printer is a device that outputs text and images by spraying picoliter-grade ink droplets onto paper through a thermal transfer method, such that a head which operates very finely to spray the ink droplets is It is necessary.

상기한 헤드는 카트리지와 연결된 잉크 공급 케이스에서 잉크를 공급받아 인쇄를 하는 바, 상기한 헤드를 사용하지 않을 때에는 헤드의 노즐을 차폐하여 외부 충격에서 보호함과 아울러 노즐의 잉크가 마르지 않도록 하는 것이다.The head is printed by receiving ink from the ink supply case connected to the cartridge. When the head is not used, the head is shielded from the head to protect the nozzle from external impact and to prevent the ink from drying out.

상기한 노즐을 보호하기 위하여 캡핑(Capping) 장치를 사용하는 바, 이는 도 4와 도 5에 도시된 바와 같이 캐리지(50)와, 상기한 캐리지(50)에 밀착되어 이동함과 아울러 노즐을 차폐하도록 구성된 캡 부재(51)와, 상기한 헤드(H)의 이동 시 캡 부재(51)가 수평 방향 및 수직 방향 이동하도록 캐리지(50)에 형성된 가이드 슬롯(52)과 가이드(53)로 구성되어 있다.In order to protect the nozzle, a capping device is used, which moves in close contact with the carriage 50 and the carriage 50 as shown in FIGS. 4 and 5, and shields the nozzle. And a guide slot 52 and a guide 53 formed in the carriage 50 to move the cap member 51 in the horizontal and vertical directions when the head H is moved. have.

상기한 바와 같은 캡핑 장치의 동작을 설명하면 프린팅 작업을 할 때는 도 4와 같이 프린트 헤드(H)가 캡 부재(51)에 접촉되지 않는 상태에서 프린팅 동작을 수행하게 되는 바, 상기한 캡 부재(51)와 프린트 헤드(H)와의 사이에는 간격이 형성되어 있다.Referring to the operation of the capping apparatus as described above, when performing the printing operation, as shown in FIG. 4, the printing operation is performed in a state in which the print head H is not in contact with the cap member 51. A gap is formed between 51) and the print head H. FIG.

즉, 상기한 프린트 헤드(H)가 차폐되어 있지 않게 되는 바, 상기한 프린팅 작업을 종료하게 되면, 상기한 프린트 헤드(H)가 이동하면서 캡 부재(51)를 밀게 된다.That is, the print head H is not shielded, and when the printing operation is finished, the print head H moves and the cap member 51 is pushed.

프린트 헤드(H)가 캡 부재(51)를 밀게 되면 상기한 캡 부재(51)가 연동하게 되는 바, 상기한 캡 부재(51)가 이동할 때에는 상기한 가이드 슬롯(52) 및 가이드(53)에 의해 상기한 캡 부재(51)가 프린트 헤드(H) 방향으로 이동하게 된다.When the print head H pushes the cap member 51, the cap member 51 is interlocked. When the cap member 51 moves, the cap member 51 moves to the guide slot 52 and the guide 53. As a result, the cap member 51 moves in the print head H direction.

캡 부재(51)가 프린트 헤드(H) 방향으로 이동하게 되면 결과적으로, 프린트 헤드(H)의 이동과 함께 캡 부재(51)가 수평 이동 및 수직 방향 이동을 함으로써, 상기한 프린트 헤드(H)를 차폐하게 되는 것이다.When the cap member 51 moves in the direction of the print head H, as a result, the cap member 51 moves horizontally and vertically together with the movement of the print head H, whereby the print head H is described above. Will be shielded.

그러나, 상기한 바와 같이 프린트 헤드의 이동에 연동하면서 캡 부재가 캐리지의 가이드 슬롯을 따라 수직 방향 및 수평 방향으로 이동하면서 프린트 헤드의 노즐을 차폐하게 되면, 상기한 캡핑 장치의 부피가 너무 크기 때문에, 결과적으로 잉크젯 프린터의 부피가 커지는 문제점이 있다.However, if the cap member moves in the vertical direction and the horizontal direction along the guide slot of the carriage while shielding the nozzles of the print head in conjunction with the movement of the print head, the volume of the capping device is too large. As a result, there is a problem that the volume of the inkjet printer becomes large.

따라서, 본 발명의 목적은 상기한 문제점을 해결하기 위한 것으로서, 잉크젯 프린터의 부피를 감소시킴과 아울러 구성을 단순화할 수 있는 잉크젯 프린터용 헤드의 캡핑 장치를 제공함에 있다.Accordingly, an object of the present invention is to provide a capping apparatus for a head for an ink jet printer, which can reduce the volume of the ink jet printer and simplify the configuration.

상기한 목적을 실현하기 위하여 본 발명은 프린트 헤드가 작동하지 않을 때 수납되는 위치에 설치된 소정 간격인 2개의 지지대와, 상기한 지지대 사이에 설치된 탄성수단에 의해 승강되도록 설치되고 프린트 헤드가 이동할 때 접촉되면서 노즐 플레이트를 차폐하는 캡 부재으로 구성함을 특징으로 한다.In order to realize the above object, the present invention provides two support members at predetermined intervals installed at positions to be accommodated when the print head is not in operation, and is installed so as to be elevated by elastic means provided between the support members, and when the print head is moved.
