Description

잉크공급장치{INK SUPPLY APPARATUS}Ink Supply Unit {INK SUPPLY APPARATUS}

본 발명은 잉크공급장치에 관한 것으로서, 보다 상세하게는 잉크가 프린터헤드를 통해 분사되지 않는 경우에도 잉크를 순환시킬 수 있는 잉크공급장치에 관한 것이다. The present invention relates to an ink supply apparatus, and more particularly, to an ink supply apparatus capable of circulating ink even when ink is not ejected through a print head.

일반적으로 종이 등 피가공물에 특정패턴을 인쇄하기 위하여 가는 노즐을 통해 잉크젯팅하여 피가공물에 인자하는 잉크젯프린터가 널리 이용된다. In general, in order to print a specific pattern on a workpiece, such as paper, an inkjet printer which prints on a workpiece by inkjetting through a thin nozzle is widely used.

도 1 및 도 2를 참조하여 종래의 인쇄장치(100)를 설명하면, 피가공물(S)이 올려지는 테이블(111) 및 상기 테이블(111)의 상부에 일축방향으로 설치되는 갠트리(112)를 포함하는 갠트리스테이지(110)와, 상기 갠트리(112)를 따라 X축방향으로 이동하고 자성물질이 포함된 잉크를 분사하는 헤드부(130)를 포함한다. 또한 상기 갠트리(112)는 상기 테이블(111)을 따라 Y축방향으로 이동가능하게 설치된다. 또한 상기 갠트리(112)에 결합하여 수평이동하는 브라켓(120)이 구비되며, 복수의 노즐(131)이 구비되는 상기 헤드부(130)는 브라켓(120)에 연결설치된다. Referring to FIGS. 1 and 2, a conventional printing apparatus 100 will be described. A table 111 on which a work S is placed and a gantry 112 installed in an axial direction on an upper portion of the table 111 may be provided. It includes a gantry stage 110 and a head portion 130 to move in the X-axis direction along the gantry 112 and to spray ink containing a magnetic material. In addition, the gantry 112 is installed to be movable in the Y-axis direction along the table 111. In addition, the bracket 120 which is coupled to the gantry 112 to move horizontally is provided, the head portion 130 is provided with a plurality of nozzles 131 is connected to the bracket 120.

이와 같은 구성을 하는 종래의 인쇄장치의 작동상태를 살펴보면, 테이블(111)에 올려진 피가공물(S)에 대하여 헤드부(130)는 갠트리(112)를 따라 X축방 향으로 이동하면서 잉크를 분사하여 특정패턴을 인쇄한다. Looking at the operating state of the conventional printing device having such a configuration, the head portion 130 is sprayed ink while moving in the X-axis direction along the gantry 112 with respect to the workpiece (S) placed on the table 111. To print a specific pattern.

다음으로, 상기 갠트리(112)가 Y축방향으로 1스탭이동하면서 상기 헤드부(130)는 상기 갠트리(112)를 따라 반대방향으로 이동하면서 잉크를 분사하여 특정패턴을 인쇄한다. 이와같이 상기 갠트리(112)는 Y축방향으로 스텝이동하게 되고, 스텝이동된 갠트리(112)를 따라 헤드부(130)는 X축방향으로 이동하면서 피가공물에 특정패턴을 인쇄하는 것이다. 다음으로, 젯팅된 잉크를 UV조사하여 경화한다. Next, while the gantry 112 moves one step in the Y-axis direction, the head part 130 moves in the opposite direction along the gantry 112 to print ink by printing a specific pattern. As such, the gantry 112 is stepped in the Y-axis direction, and the head portion 130 moves in the X-axis direction along the stepped gantry 112 to print a specific pattern on the workpiece. Next, the jetted ink is cured by UV irradiation.

한편, 도 3은 상기 헤드부에 잉크를 공급하는 장치가 도시한 것이다. 종래의 잉크공급장치는 잉크저장탱크(210)와, 펌프(221)와, 잉크를 헤드부(130)에 공급하는 공급관(220)과, 상기 공급관(220)을 개폐하는 개폐수단(222)과, 저장부(240)를 포함한다. 또한 상기 잉크저장탱크(210)에는 교반기(230)가 더 구비된다. 3 shows an apparatus for supplying ink to the head portion. The conventional ink supply apparatus includes an ink storage tank 210, a pump 221, a supply pipe 220 for supplying ink to the head portion 130, opening and closing means 222 for opening and closing the supply pipe 220 and It includes a storage unit 240. In addition, the ink storage tank 210 is further provided with a stirrer 230.

이와 같이 구성된 종래의 잉크공급장치는 잉크저장탱크(210)에 수용된 잉크를 교반기(230)로 교반하면서 공급관(220)을 통해 헤드부(130)로 공급한다. 그런데, 유지보수나 기타 사유로 인해 작업이 중단된 경우, 상기 개폐수단(222)을 이용해 공급관을 폐쇄하여 잉크의 공급을 중단한다. 이 상태에서도 공급관(220)에는 잉크가 잔류된 상태로 일정시간이 경과되게 되는데, 이와 같이 공급관(220)이나 저장부(240) 또는 헤드부(130)내에 잔류된 잉크는 시간이 경과함에 따라 침전현상이 일어나게 된다. The conventional ink supply apparatus configured as described above supplies the head portion 130 through the supply pipe 220 while stirring the ink contained in the ink storage tank 210 with the stirrer 230. However, when the work is stopped due to maintenance or other reasons, the supply pipe is closed by using the opening and closing means 222 to stop supply of ink. Even in this state, a predetermined time elapses with ink remaining in the supply pipe 220. As such, the ink remaining in the supply pipe 220, the storage 240, or the head 130 is settled as time passes. The phenomenon occurs.

따라서 중단된 작업을 개시하고자 할 경우, 잉크희석제를 이용해 상기 저장부와 헤드부를 세척하지만, 세척이 용이하지 않다는 문제점이 있다. Therefore, if you want to start the interrupted work, but the washing and the head portion using the ink diluent, but there is a problem that the washing is not easy.

본 발명은 상술한 문제점을 해결하기 위하여 안출된 것으로서, 본 발명의 목적은 잉크가 프린터헤드를 통해 분사되지 않는 경우에도 잉크를 순환시킬 수 있는 잉크공급장치를 제공함에 있다. SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problem, and an object of the present invention is to provide an ink supply apparatus capable of circulating ink even when ink is not ejected through the print head.

본 발명에 따르면, 잉크가 프린터헤드를 통해 분사되지 않는 경우에도 잉크를 순환시킬 수 있는 효과가 있다. According to the present invention, the ink can be circulated even when the ink is not ejected through the print head.

따라서 잉크의 침전현상을 방지할 수 있다. Therefore, it is possible to prevent the precipitation of ink.

이하, 첨부된 도면을 참조하여 본 발명에 의한 실시예의 구성 및 작용을 구 체적으로 설명한다. Hereinafter, with reference to the accompanying drawings will be described in detail the configuration and operation of the embodiment according to the present invention.

도 4는 본 발명에 의한 잉크공급장치를 도시한 것이다. 도시된 바와 같이, 잉크저장탱크(10)와, 펌프(21)와, 잉크를 헤드부(130)에 공급하는 공급관(20)과, 상기 공급관(20)을 개폐하는 제1개폐수단(22)과, 저장부(40)를 포함한다. 또한 상기 잉크저장탱크(10)에는 교반기(50)가 더 구비된다. 이는 도 3에 도시된 종래의 구성요소와 동일하므로 여기서는 구체적인 설명은 생략한다. 4 shows an ink supply apparatus according to the present invention. As shown, the ink storage tank 10, the pump 21, the supply pipe 20 for supplying ink to the head portion 130, and the first opening and closing means 22 for opening and closing the supply pipe 20 And a storage unit 40. In addition, the ink storage tank 10 is further provided with a stirrer (50). This is the same as the conventional component shown in Figure 3, so a detailed description thereof will be omitted.

본 발명에 의한 잉크공급장치는 특히 제2개폐수단(31)과 바이패스관(30)이 더 구비되는 것을 알 수 있다. In particular, it can be seen that the ink supply apparatus according to the present invention further includes the second opening and closing means 31 and the bypass pipe 30.

상기 제2개폐수단(31)은 상기 공급관(20)을 개폐하는 공지의 요소이다. The second opening and closing means 31 is a known element that opens and closes the supply pipe 20.

또한 상기 바이패스관(30)은 상기 제2개폐수단(31)의 폐쇄시, 상기 공급 관(20)으로 공급되는 잉크를 상기 잉크저장탱크(10)로 순환시키는 구성요소이다. In addition, the bypass pipe 30 is a component that circulates the ink supplied to the supply pipe 20 to the ink storage tank 10 when the second opening and closing means 31 is closed.

특히, 상기 잉크는 화이트 등 바탕색잉크인 것이 바람직하다. In particular, the ink is preferably a background color ink such as white.

이하에서는 본 발명에 의한 잉크공급장치의 작동상태를 설명한다. Hereinafter, the operating state of the ink supply apparatus according to the present invention will be described.

먼저, 잉크저장탱크(10)에 저장된 잉크를 교반기(50)를 이용해 충분히 교반한다. 이 상태에서 공급관(20)을 통해 저장부(40) 및 헤드부(130)로 잉크를 공급한다. First, the ink stored in the ink storage tank 10 is sufficiently stirred using the stirrer 50. In this state, ink is supplied to the storage unit 40 and the head unit 130 through the supply pipe 20.

만약, 유지보수 등 기타 사유로 잉크가 헤드부(130)로 공급되는 것이 차단되어야 할 경우, 펌프(21)를 그대로 작동시키고, 그 대신 제2개폐수단(31)을 이용해 공급되는 잉크의 이송경로를 변경하여 다시 공급관(20)으로 순환시키는 것이다. If, for maintenance or other reasons it is necessary to block the supply of ink to the head 130, the pump 21 is operated as it is, instead of the transfer path of the ink supplied using the second opening and closing means (31) By changing the circulating back to the supply pipe (20).
