본 발명은 잉크젯 프린터의 잉크 흡입장치에 관한 것으로서, 더욱 상세하게는 정역회전되는 클러치축의 양측에 서로 반대방향으로 작동되는 클러치스프링을 갖는 클러치휠을 설치하여 한쪽이 잉크를 흡입할 때 반대쪽은 흡입하지 않도록 함으로써, 칼라 및 흑백잉크를 사용하는 프린터에서 잉크를 선택적으로 흡입하여 노즐을 청결하게 할수 있는 잉크젯 프린터의 잉크 흡입장치에 관한 것이다.The present invention relates to an ink suction device of an inkjet printer, and more particularly, by installing a clutch wheel having clutch springs operated in opposite directions on both sides of a clutch shaft which is rotated forward and backward, when one side sucks ink, the other side does not suck the ink. The present invention relates to an ink suction device of an ink jet printer capable of cleaning the nozzles by selectively sucking ink in a printer using color and black and white ink.
일반적으로 잉크젯 프린터에서 잉크가 담긴 카트리지의 노즐에 묻은 잉크를 흡입하여 이를 청소해주는 장치는 도 1에 도시된 바와 같다. 즉 가이드를 따라 이동되는 한쌍의 흑백카트리지(1)와 칼라카트리지(1a)가 구비되고 이들에는 잉크를 토출하는 노즐(2)(2a)이 각각 형성되어 있다. 그리고 이들 노즐(2)(2a)과 대응되도록 흡입구(3)(3a)가 구비되며, 이들 흡입구(3)(3a)와 튜브(4)로 연결된 흡입장치(5)가 구비되며 흡입장치(5)의 일측에는 흡입된 잉크를 배출할 때 이를 흡착시키는 흡착부(6)가 구비된다.In general, the apparatus for sucking and cleaning the ink on the nozzle of the cartridge containing the ink in the inkjet printer as shown in FIG. That is, a pair of black and white cartridges 1 and color cartridges 1a which are moved along the guide are provided, and nozzles 2 and 2a for ejecting ink are respectively formed. Inlet ports 3 and 3a are provided to correspond to these nozzles 2 and 2a, and suction devices 5 connected to these suction ports 3 and 3a and the tube 4 are provided. One side of the) is provided with an adsorption portion (6) for adsorbing it when discharging the sucked ink.
이처럼 구성된 잉크 흡입장치는 잉크가 노즐을 통하여 배출되는 과정에서 노즐에 묻은 잔류잉크를 간헐적으로 흡입하여 이를 제거해 주어야된다. 즉 카트리지(1)(1a)가 가이드를 따라 이동하면서 노즐(2)(2a)을 통하여 칼라잉크 또는 흑백잉크를 선택적으로 토출하여 프린트하는 과정에서 노즐에 잔류잉크가 발생된다. 따라서 프린트하는 과정에서 노즐에 묻은 잉크를 간헐적으로 제거하기 위해 각 카트리지(1)(1a)가 흡입구(3)(3a) 위치로 이동되면 흡입구(3)(3a)가 해당 노즐(2)(2a)과 밀착되며 이후 흡입장치(5)가 작동되어 노즐(2)(2a)에 묻은 잉크가 흡입되어 튜브(4)를 통하여 흡착부(6)로 배출된다.The ink suction device configured as described above should remove the ink remaining in the nozzle intermittently while the ink is discharged through the nozzle. That is, while the cartridges 1 and 1a move along the guide, residual ink is generated in the nozzle during the process of selectively discharging the color ink or the black and white ink through the nozzles 2 and 2a to print. Therefore, when each cartridge (1) (1a) is moved to the inlet (3) (3a) position in order to intermittently remove the ink on the nozzle during printing, the inlet (3) (3a) is moved to the nozzle (2) (2a) ), And then the suction device 5 is operated to suck the ink from the nozzles 2 and 2a and discharge the ink to the suction part 6 through the tube 4.
도 2a, 2b는 종래 흡입장치의 작동상태를 나타낸 측단면도 로서, 이는 일본 특개평 7-156419 호에 개시돼 있다. 축(7b)을 중심으로 회전되는 정역회전되는 휠(7)의 내부에 양측으로 형성된 원호형의 캠홈(7a)이 형성되고 캠홈(7a)에는 로울러(8)가 각각 설치되어 있으며 잉크를 흡입하는 튜브(4)가 로울러(8)와 대응토록 설치되어 있다.2A and 2B are side cross-sectional views showing an operating state of a conventional suction device, which is disclosed in Japanese Patent Laid-Open No. 7-156419. An arc-shaped cam groove 7a formed at both sides is formed inside the wheel 7 which is rotated about the shaft 7b, and rollers 8 are respectively installed in the cam groove 7a to suck ink. The tube 4 is provided so as to correspond to the roller 8.
이처럼 구성된 종래의 흡입장치는 양방향으로 회전되는 스테핑모터 등에 의해 정역 회전되는 휠(7)이 양측에 구비되고 이들 각 휠(7)에 형성된 캠홈(7a)과 로울러(8)에 의해 튜브(4)가 선택적으로 압축된다. 따라서 흑백과 칼라잉크가 각각 내장된 카트리지의 노즐이 선택적으로 흡입되어 잔류잉크가 노즐에 발생되지 않도록 이를 제거해준다.The conventional suction device configured as described above has a wheel 7 which is rotated forward and backward by a stepping motor or the like that is rotated in both directions, and the tube 4 is formed by the cam groove 7a and the roller 8 formed on each of the wheels 7. Is optionally compressed. Therefore, the nozzles of the cartridge containing the black and white color ink are selectively sucked to remove the residual ink from the nozzle.
그러나 휠(7)에 형성된 캠홈(7a)의 각도에 따라 로울러(8)의 작동상태가 변하기 때문에 캠홈(7a)의 가공이 어려우며 특히 각 휠(7)의 외주면에 이들을 구동시키기 위한 기어부가 별도로 제작됨으로 구성이 복잡해지고 생산성이 저하되는 등의 단점이 있다.However, since the operation state of the roller 8 changes according to the angle of the cam groove 7a formed in the wheel 7, the machining of the cam groove 7a is difficult, and in particular, a gear part for driving them on the outer circumferential surface of each wheel 7 is manufactured separately. As a result, the configuration is complicated and productivity is lowered.
본 발명은 종래의 문제점을 감안하여 개발한 것으로서, 본 발명의 목적은 클러치축의 양측에 서로 반대방향으로 작동되는 클러치스프링을 갖는 클러치휠을 설치하고 이들 휠에 로울러를 각각 설치함으로써, 이들 클러치휠이 선택적으로 회전될 때 튜브가 로울러에 의해 압착되면서 잉크가 흡입됨으로 구성이 간소화되고 가공이 편리하여 생산성이 향상되는 잉크젯 프린터의 잉크 흡입장치를 제공함에 있다.SUMMARY OF THE INVENTION The present invention was developed in view of the conventional problems, and an object of the present invention is to install clutch wheels having clutch springs operated in opposite directions on both sides of a clutch shaft, and to install these roller wheels on these wheels, respectively.

이와 같이 구성된 본 발명은 정역회전되는 회전축(11)의 외주면에 클러치축(20)이 끼워지고 클러치축(20)의 양단에는 로울러(27)를 갖는 클러치휠(25)이 각각 설치된다. 그리고 각 클러치휠(25)을 감싸는 흡입케이스(10)가 구비되며 흡입케이스(10)에는 클러치휠(25)의 회전시 로울러(27)에 의해 압착되는 튜브(4)가 내장된다. 또한 클러치휠(25)과 클러치축(20)의 사이에는 서로 반대방향으로 감긴 클러치스프링(21)이 설치된다.In the present invention configured as described above, the clutch shaft 20 is fitted to the outer circumferential surface of the rotating shaft 11 which is rotated forward and backward, and clutch wheels 25 having rollers 27 are provided at both ends of the clutch shaft 20, respectively. In addition, a suction case 10 is provided to surround each clutch wheel 25, and the suction case 10 has a tube 4 compressed by the roller 27 when the clutch wheel 25 is rotated. In addition, between the clutch wheel 25 and the clutch shaft 20, a clutch spring 21 wound in opposite directions is provided.
이처럼 조립되는 본 발명의 흡입장치는 모터의 작동으로 회전축(11)이 정회전 되면 정방향으로 감긴 클러치스프링이 작동된다. 예컨데 도 3에 도시된 바와 같이 클러치축(20)의 우측에 있는 클러치스프링(21)이 정방향으로 감겼다고 가정하면, 정방향으로 회전되는 회전축(11)과 일체로 회전되는 클러치축(20)에 의해 클러치디스크(22)가 회전된다. 이때 절곡부(23)를 통하여 클러치디스크와 연결된 클러치스프링(21)이 회전되며 정방향으로 감긴 우측의 클러치스프링(21)은 감기게 되고 끼움부(26)가 클러치스프링을 통하여 클러치축(20)과 연결된다.In the suction device of the present invention assembled as described above, when the rotating shaft 11 is rotated forward by the operation of the motor, the clutch spring wound in the forward direction is operated. For example, as shown in FIG. 3, assuming that the clutch spring 21 on the right side of the clutch shaft 20 is wound in the forward direction, the clutch shaft 20 that is integrally rotated with the rotation shaft 11 that rotates in the forward direction The clutch disk 22 is rotated by this. At this time, the clutch spring 21 connected to the clutch disk through the bent portion 23 is rotated, and the clutch spring 21 on the right side wound in the forward direction is wound and the fitting portion 26 is connected to the clutch shaft 20 through the clutch spring. Connected.
따라서 클러치축(20)의 우측에 놓인 클러치휠(25)이 회전되고 이의 로울러(27)에 의해 튜브(4)가 압착된다. 튜브의 압착으로 펌핑작용이 일어나게 되고 튜브(4)와 연결된 해당 흡입구(3)(3a)를 통하여 잉크카트리지의 노즐에 묻은 잉크가 흡입 배출된다. 또한 회전축이 역방향으로 회전되면 역방향으로 감긴 좌측의 클러치스프링이 작동되고 이후 좌측의 클러치휠(25)을 통하여 튜브가 압착되고 해당 잉크카트리지의 노즐에 묻은 잉크가 흡입 배출된다.Accordingly, the clutch wheel 25 placed on the right side of the clutch shaft 20 is rotated and the tube 4 is compressed by the roller 27 thereof. The pumping action is caused by the compression of the tube, and the ink adhered to the nozzle of the ink cartridge is sucked out through the corresponding suction ports 3 and 3a connected to the tube 4. In addition, when the rotating shaft is rotated in the reverse direction, the clutch spring on the left side of the reverse side is operated, and then the tube is compressed through the clutch wheel 25 on the left side, and the ink deposited on the nozzle of the ink cartridge is sucked out.
이상에서와 같이 본 발명에 따르면 정역회전되는 회전축과 일체로 회전되는 클러치축의 외주면 양측에 서로 반대방향으로 감긴 클러치스프링이 구비되고 이들 클러치스프링이 감기는 방향으로 회전될 때 함께 회전되면서 튜브를 압착하는 클러치휠이 구비된다. 따라서 튜브가 선택적으로 압착됨으로 흑백,칼라잉크카트리지의 노즐을 청소해줄수 있으며, 특히 클러치스프링을 이용함으로 구성이 간소화되어 제조하기 편리한 등의 효과가 있다.As described above, according to the present invention, clutch springs wound in opposite directions are provided on both sides of the outer circumferential surface of the clutch shaft which is integrally rotated with the forward and reverse rotation shafts, and the clutch springs are rotated together when the clutch springs are rotated in the winding direction to compress the tubes. Clutch wheel is provided. Therefore, the tube is selectively squeezed to clean the nozzles of the black and white and color ink cartridges, and in particular, the configuration is simplified by using the clutch spring, which is convenient to manufacture.
