As a result, there is an advantage of forming a good meniscus during dispersion to improve the quality of printing and to improve the reliability of the apparatus.
Description
본 발명은 잉크젯 프린터의 잉크 순환장치에 관한 것으로, 특히 시스템 내 분산 안정성을 위해 잉크 공급통의 높이 차에 의한 자연적인 순환보다는 순환 펌프를 이용한 강제 순환을 실시하도록 하여 비중이 높은 불용성 안료 잉크 분사 시 시스템 내 침전을 방지하여 순환 및 공급 불균형을 해소하고, 분산 안정성을 유지할 수 있도록 한 잉크젯 프린터의 잉크 순환장치에 관한 것이다.The present invention relates to an ink circulating device of an inkjet printer, and in particular, in order to disperse insoluble pigment ink having a high specific gravity by performing forced circulation using a circulation pump rather than a natural circulation caused by a difference in height of an ink supply container for dispersion stability in a system. The present invention relates to an ink circulating device of an inkjet printer, which prevents settling in a system to solve circulation and supply imbalances and maintain dispersion stability.
일반적으로 잉크젯 프린터에서 비중이 높은 불용성 안료 잉크 분사 시 시스템 내 분산 안정성 유지가 중요한 요소이다. 시스템 내에 침전이 발생한다면 전체적인 순환 및 공급에 있어서 불균형을 가져올 뿐 아니라 결과적으로 분산 시 미니스커스(meniscus) 형성에도 영향을 미쳐 불안정 분사 및 미 분사를 초래하기도 한다.In general, it is important to maintain dispersion stability in the system when insoluble pigment ink is sprayed with high specific gravity in inkjet printers. Sedimentation in the system not only leads to imbalances in the overall circulation and supply, but also affects the formation of meniscus upon dispersion, leading to unstable and unsprayed sprays.
도 1은 종래 잉크젯 프린터의 잉크 순환장치의 블럭 구성도로서, 이에 도시한 바와 같이, 용지에 인자하기 위한 잉크젯 헤드(1)와, 잉크젯 헤드(1)에 잉크를 공급하는 순환배관(2)의 양측에 배치되는 주 잉크 저장통(3) 및 부 잉크 저장통(4)과, 주 잉크 저장통(3)과 부 잉크 저장통(4) 사이에 설치되는 잉크 레벨 펌프(ink level pump)(5)와, 부 잉크 저장통(4)과 잉크젯 헤드(1) 사이에 설치되는 플라이밍 펌프(priming pump)(6)로 구성되어 있다. 그리고 상기 주 잉크 저장통(3)과 부 잉크 저장통(4)의 내부에는 교반장치(7),(8)가 각각 설치된 구성으로 되어 있다.1 is a block diagram of an ink circulation device of a conventional inkjet printer. As shown therein, an inkjet head 1 for printing onto a sheet and a circulation pipe 2 for supplying ink to the inkjet head 1 are shown. A main ink reservoir (3) and a secondary ink reservoir (4) disposed on both sides, an ink level pump (5) provided between the primary ink reservoir (3) and the secondary ink reservoir (4); It consists of a priming pump 6 provided between the ink reservoir 4 and the inkjet head 1. The main ink reservoir 3 and the secondary ink reservoir 4 are each provided with stirring devices 7 and 8, respectively.
이와 같은 종래의 잉크젯 프린터의 잉크 순환장치는 주 잉크 저장통(3)과 부 잉크 저장통(4) 내의 잉크가 잉크 레벨 펌프(5)의 펌핑에 의해 레벨이 유지되고, 주 잉크 저장통(3)과 부 잉크 저장통(4)의 높이 차에 의한 자연 순환으로 잉크가 순환된다.In the ink circulating device of such a conventional inkjet printer, the ink in the main ink reservoir 3 and the secondary ink reservoir 4 is maintained at the level by pumping the ink level pump 5, and the main ink reservoir 3 and the secondary ink reservoir are maintained. The ink is circulated by the natural circulation caused by the height difference of the ink reservoir 4.
이와 같이 종래의 잉크젯 프린터의 잉크 순환장치는 주 잉크 저장통(3)과 부 잉크 저장통(4)의 상대 높이에 따라 잉크의 자연 순환이 이루어져 분산 안정성을 유지하게 되며, 이에 따라 침전 속도가 빠른 잉크는 높이 차이에 의한 순환으로 침전을 제거하기에는 어려움이 있고, 일단 시스템 내 침전이 진행되면 높이 수정이 필요하게되는 문제점이 있었다.As such, the ink circulating device of the conventional inkjet printer maintains dispersion stability by naturally circulating the ink according to the relative height of the main ink reservoir 3 and the secondary ink reservoir 4, and thus, the ink having a fast deposition rate There is a difficulty in removing the precipitate due to the circulation due to the height difference, and once the precipitation in the system is in progress, there is a problem that the height correction is required.
본 발명은 상기한 바와 같은 종래의 문제점 및 결함을 해소하기 위하여 안출한 것으로, 시스템 내 분산 안정성을 위해 잉크 공급통의 높이 차에 의한 자연적인 순환 보다는 순환 펌프를 이용한 강제 순환을 실시하도록 하여 비중이 높은 불용성 안료 잉크 분사 시 시스템 내 침전을 방지하여 순환 및 공급 불균형을 해소하고, 분산 안정성을 유지할 수 있게 되는 잉크젯 프린터의 잉크 순환장치를 제공하고자 함에 목적이 있다.The present invention has been made to solve the above problems and defects as described above, the specific gravity is to be carried out by using a circulation pump rather than a natural circulation due to the height difference of the ink supply container for dispersion stability in the system It is an object of the present invention to provide an ink circulating device of an inkjet printer, which can prevent precipitation in the system when spraying high insoluble pigment ink, thereby eliminating circulation and supply imbalance, and maintaining dispersion stability.
위와 같은 목적을 달성하기 위하여 본 발명에 의한 잉크젯 프린터의 잉크 순환장치는 잉크젯 헤드가 배치되는 순환배관의 양측부에 주 잉크 저장통과 부 잉크 저장통이 연결되고, 잉크젯 헤드와 주 잉크 저장통 사이에 순환 펌프가 연결되어 불용성 안료 잉크를 안정하게 분사하도록 구성된다.In order to achieve the above object, the ink circulation device of the ink jet printer according to the present invention has a main ink reservoir and a secondary ink reservoir connected to both sides of a circulation pipe where the ink jet head is disposed, and a circulation pump between the ink jet head and the main ink reservoir. Is connected so as to stably spray the insoluble pigment ink.
잉크젯법이 디스펜서의 역할을 제대로 하려면 재료적인 측면에서 목적하는 물질이 물이나 용매에 의해 회석되어 잉크젯 헤드 내에서 내구성이 있는 안정된 유체로 만들어져야 한다. 여기서 만일 목적하는 물질이 잉크 제조 시 물이나 용매에 녹지 않는 안료이고 또 비중이 상대적으로 높은 물질이라면 잉크젯 헤드 내에서는 물론 주입 튜브나 통에서의 분산 안정성 문제가 유발되며, 또 이러한 잉크는 헤드에 유입되는 흐름이 원할하지 못하여 분산 안정성에도 영향을 미치게 된다. 본 발명은 이러한 배경에 의해 인쇄 공정 시 분산을 유지시키고, 분산 안정성을 확보하기 위하여 개발된 것이다.In order for the inkjet method to function properly as a dispenser, the desired material in terms of material must be dilute with water or a solvent to make a durable stable fluid in the inkjet head. Here, if the target material is a pigment that is insoluble in water or solvents in the manufacture of ink and has a relatively high specific gravity, the dispersion stability problem in the injection tube or the barrel, as well as in the inkjet head, is caused. The flow is not desired, which affects dispersion stability. The present invention has been developed to maintain dispersion during the printing process and secure dispersion stability based on this background.

이와 같은 본 발명에 의한 잉크젯 프린터의 잉크 순환장치는 주 잉크 저장통(3)와 부 잉크 저장통(4) 내의 잉크가 잉크 레벨 펌프(5)의 펌핑에 의해 레벨이 유지되고, 주 잉크 저장통(3)과 부 잉크 저장통(4)의 높이 차 및 순환 펌프(9)의 펌핑력에 잉크가 순환된다.The ink circulating device of the ink jet printer according to the present invention maintains the level of the ink in the main ink reservoir 3 and the secondary ink reservoir 4 by pumping the ink level pump 5, and the main ink reservoir 3 Ink is circulated by the height difference of the widow ink reservoir 4 and the pumping force of the circulation pump 9.
이와 같이 본 발명에 의한 잉크젯 프린터의 잉크 순환장치는 순환 펌프(9)의 역할로 잉크가 높이 차에 의한 순환 효과가 원활하게 되고, 침전에 의해 순환 속도가 저하되는 현상이 방지되며, 순환 펌프(9)를 정밀 제어함에 의해 분산 안정 최적점을 쉽게 도출할 수 있게 된다.As described above, the ink circulating device of the ink jet printer according to the present invention has a role of the circulation pump 9, so that the circulation effect of the ink due to the height difference is smooth, and the phenomenon that the circulation speed decreases due to precipitation is prevented, By precisely controlling 9), it is possible to easily derive the dispersion stability optimum point.
이상에서 설명한 바와 같은 잉크젯 프린터의 잉크 순환장치는 시스템 내 분산 안정성을 위해 잉크 공급통의 높이 차에 의한 자연적인 순환보다는 순환 펌프를 이용한 강제 순환을 실시하도록 구성되어 있으므로 비중이 높은 불용성 안료 잉크 분사 시 시스템 내 침전을 방지하여 순환 및 공급 불균형을 해소하고, 분산 안정성을 유지할 수 있는 이점이 있으며, 결과적으로 분산 시 미니스커스(meniscus)를 양호하게 형성하여 인자의 품질을 향상하고 장치의 신뢰성을 향상하는 이점이 있다.As described above, the ink circulating device of the inkjet printer is configured to perform forced circulation using a circulation pump rather than a natural circulation caused by the difference in height of the ink supply container for dispersing stability in the system. By preventing settling in the system, there is an advantage of eliminating circulation and supply imbalance and maintaining dispersion stability. As a result, it is possible to form a good miniiscus at the time of dispersion, improving the quality of printing and improving the reliability of the device. This has the advantage.
