Abstract

PURPOSE: An automatic pressure controlling device embedded in an external ink supply device for a printer is provided to always and regularly maintain ink pressure actuated between a backflow prevention device and a head, thereby automatically preventing the malfunction of the printer caused by a pressure increase. CONSTITUTION: An automatic pressure controlling device embedded in an external ink supply device for a printer includes an automatic ink pressure controlling member (500). The automatic ink pressure controlling member is installed on an ink supply hose (200) between a backflow prevention device and a head (300). When the ink pressure between the backflow prevention device and the head is increased, the automatic ink pressure controlling member decreases the ink pressure by sucking some of ink. When the ink pressure between the backflow prevention device and the head is decreased, the ink is automatically discharged so that the ink pressure is always and regularly maintained. The automatic ink pressure controlling member is composed of a vacuum pack type pressure controller (510). The vacuum pack type pressure controller enables a breathing exercise which is expanded convexly when ink is sucked and shrank to be flat and vacuum-seals a thin synthetic resin film.

프린터의 외부설치용 잉크공급장치에 부설되는 압력자동조절장치{The Pressure self-adjustment equipment attached to the ink feed unit for external installation of a printer}Pressure self-adjustment equipment attached to the ink feed unit for external installation of a printer}

본 발명은 잉크공급장치가 외부에 설치되는 잉크젯 프린터 동작 중 헤드측의 잉크압력상승에 의해 발생되는 결함(흘러내림, 잉크퍼짐현상 등)을 아주 간단하게 방지할 수 있을 뿐 아니라 설치 적용에 따른 비용부담까지 최소화될 수 있는 새로운 프린터의 외부설치용 잉크공급장치에 부설되는 압력자동조절장치에 관한 것이다.
The present invention can not only easily prevent defects (flowing, ink spreading phenomenon, etc.) caused by the ink pressure increase on the head side during the operation of the inkjet printer in which the ink supply device is installed outside, but also the cost of the installation application. The present invention relates to a pressure automatic control device attached to an ink supply device for external installation of a new printer that can minimize the burden.

잉크젯 프린터 기기의 외부에 대용량 잉크용기(사용시간과 리필주기가 비교적 긴)가 설치되는 종래의 외부 설치용 잉크공급장치는, A conventional external installation ink supply device in which a large-capacity ink container (relatively long use time and refill cycle) is installed outside the inkjet printer device,

본원 출원인에 의해 출원되고 등록까지 허여된 특허출원번호:10-2009-0004914호를 비롯하여 현재까지 다양한 구조들이 속속 개발되고 있다.
Various structures have been developed one after another, including Patent Application No.:10-2009-0004914, filed by the present applicant and granted until registration.

한편, 종래의 외부 설치용 잉크공급장치의 기본적인 구조는, 프린터 기기의 외부에 크기가 비교적 큰 대용량의 잉크용기(100)가 설치되고, 상기 잉크용기(100)와 프린터의 헤드(300) 사이에는 잉크공급호스(200)가 구비되는 동시에 상기 잉크용기(100) 및 잉크공급호스(200)에는 내부 잉크의 역류를 방지할 수 있는 역류방지장치(통상 체크밸브 및 기타 역류를 방지할 수 있는 다양한 구조들이 적용되어 있음. 180)가 구비된 구조를 갖는다.
On the other hand, the basic structure of the conventional ink supply device for external installation, the ink container 100 of a relatively large size is installed on the outside of the printer device, the ink between the ink container 100 and the head of the printer 300 At the same time the supply hose 200 is provided, the ink container 100 and the ink supply hose 200 has a backflow prevention device (usually check valves and other various structures to prevent the backflow of the internal ink can be prevented) It has a structure equipped with 180).

그런데, 상기한 외부 설치용 종래의 잉크공급장치는, 대용량의 잉크용기(100)가 연결되어 있음에 따라,By the way, in the conventional ink supply apparatus for external installation, as the ink container 100 of a large capacity is connected,

인쇄의 연속성을 크게 담보할 수 있을 뿐 아니라 잉크의 교체주기(=리필주기) 또한 더욱 늘릴 수 있는 장점이 제공되는 것은 분명하지만,Obviously, not only can the continuity of printing be greatly secured, but the ink replacement cycle (= refill cycle) can be further increased.

잉크용기(100) 및 잉크공급호스(200)에 설치되는 잉크용액에 대한 역류방지장치(180)로 인해,Due to the backflow prevention device 180 for the ink solution installed in the ink container 100 and the ink supply hose 200,

헤드측에 연결된 잉크공급호스(200)의 내부 잉크에 일정한 압력이 걸려 사용 중 상당한 결함(잉크가 헤드측으로 흘러내리거나 헤드주변을 오염하고, 인쇄지에 잉크퍼짐현상이 발생하는 등)이 발생하고,The internal ink of the ink supply hose 200 connected to the head side is subjected to a constant pressure, which causes considerable defects during use (ink flows down to the head side, contaminates the head surroundings, and ink spreads on the printing paper).

이는 인쇄품질과 프린터의 성능향상에 많은 장애와 한계점을 가질 수 밖에 없는 상당한 문제점이 있었다.
This has had a considerable problem of having many obstacles and limitations in improving the print quality and the performance of the printer.

즉, 통상 인쇄가 시작되면 헤드에서 분사되는 잉크의 소모량에 비례한 잉크가 헤드측으로 공급된다.That is, when printing starts normally, ink proportional to the consumption amount of ink ejected from the head is supplied to the head side.

그리고, 인쇄의 진행에 따라 헤드측으로 잉크가 계속 주입되다가 헤드의 위치이동이나 다른 조건셋팅 등의 행위를 위해 일시적으로 인쇄중단 및 잉크공급이 차단되면,If the ink is continuously injected into the head as printing progresses, and the printing stops and the ink supply is temporarily interrupted for the action of moving the head or setting other conditions,

상기 역류방지장치로 인해 뒤로 백(back)하는 자체가 불가능하기 때문에 결국 상기 역류방지장치와 헤드에 존재하는 잉크에 일정한 압력이 걸리게 된다.
Since the backflow prevention device itself is impossible to back, the pressure existing in the backflow prevention device and the head is constant.

역류방지장치와 헤드에 사이의 잉크에 일정한 압력이 풀리지 않고 일정한 타임 동안 걸리고 누적되면 헤드측에 물방울과 같은 잉크 맺힘현상이 나타날 수 있고,When ink is accumulated between the backflow prevention device and the head for a certain time without being released, a condensation such as water droplets may appear on the head side.

심하면 흘러내려서 헤드 주변을 오염시킬 수 있을 뿐 아니라, 인쇄가 제기될 경우 잉크퍼짐현상 그리고 원하는 정밀한 색상을 구현하지 못하는 등 심각한 인쇄품질저하의 원인이 될 수 있다.
Severe runoff can contaminate the heads and cause serious print quality degradation, such as ink spreading and inability to produce the desired color colours.

이에 본 발명에서는 역류방지장치(180)와 헤드 사이의 잉크에 일정한 압력이 걸릴 경우 잉크의 일부를 흡입하여 그 압력을 자동으로 풀어주고, 인쇄의 속계에 따라 압력이 낮아지면, 흡입된 잉크가 자동으로 배출되며 상황에 따라 이를 반복함으로써, 결국 역류방지장치(180)와 헤드 사이에 걸리는 잉크 압력을 항시 일정하게 자동으로 조절·유지될 수 있고, 그것(압력상승)으로 인해 발생될 수 있는 프린터의 상당한 결함(흘러내림 및 잉크퍼짐현상, 인쇄품질저하 등)이 자동으로 방지될 수 있는 프린터의 외부설치용 잉크공급장치에 부설되는 압력자동조절장치를 제공함에 주안점을 두고 그 기술적 과제로서 완성한 것이다.
Accordingly, in the present invention, when a certain pressure is applied to the ink between the backflow preventing device 180 and the head, the ink is sucked out to release the pressure automatically, and when the pressure is lowered according to the printing speed, the sucked ink is automatically By repeating this according to the situation, the ink pressure applied between the backflow prevention device 180 and the head can be automatically and constantly adjusted constantly and constantly, and it can be caused by the pressure rise of the printer. The technical object of the present invention is to provide a pressure automatic control device attached to an ink supply device for external installation of a printer, in which significant defects (such as spillage and ink spreading and print quality deterioration) can be automatically prevented.

위 기술적 과제를 달성하기 위한 본 발명은 프린터 기기의 외부에 잉크용기(100)가 설치되고, 그 잉크용기(100)와 헤드(300) 사이에는 잉크공급호스(200)가 구비되며, 상기 잉크용기(100) 및 잉크공급호스(200)에는 내부 용액의 역류를 방지하기 위한 역류방지장치(180)가 구비되는 프린터 잉크공급장치에 있어서, 상기 역류방지장치(180)와 헤드(300) 사이의 잉크공급호스(200)에, 잉크의 압력이 증가되면 잉크일부를 흡입하여 풀어주고, 낮아지면 자동으로 배출되어 항시 일정한 압력이 유지될 수 있도록 하는 잉크압력 자동조절수단(500)을 추가로 더 설치시켜서 된 것이다.
The present invention for achieving the above technical problem is the ink container 100 is installed on the outside of the printer device, the ink supply hose 200 is provided between the ink container 100 and the head 300, the ink container In the printer ink supply device 100 and the ink supply hose 200 is provided with a backflow prevention device 180 for preventing the back flow of the internal solution, the ink between the backflow prevention device 180 and the head 300 In addition to the supply hose 200, the ink pressure automatic control means 500 is further installed to suck and release a portion of the ink when the pressure of the ink is increased, and automatically discharged when the pressure is lowered so that a constant pressure is always maintained. It is.

이와 같이 본 발명에서 제시된 프린터의 외부설치용 잉크공급장치에 부설되는 압력자동조절장치는, 역류방지장치와 헤드 사이에 존재하는 잉크의 압력이 증가하면 일부의 잉크를 흡입하여 낮추거나 또는 헤드에서의 일부 공기를 배출하여 낮추어 항시 일정한 압력이 유지될 수 있게 조절함에 따라, 압력의 상승으로 인해 헤드측에 나타날 수 있는 결함(잉크의 흘러내림현상, 헤드주변오염, 인쇄 재개시의 잉크퍼짐현상 등)의 근본적인 방지 및 최소화에 크게 기여할 수 있게 되는 등 그 기대되는 바가 실로 다대한 발명이다.
Thus, the pressure automatic control device attached to the ink supply device for external installation of the printer proposed in the present invention, when the pressure of the ink existing between the backflow prevention device and the head is increased by sucking some of the ink or lowering the part of the head As the air is discharged and lowered to maintain a constant pressure at all times, the defects that may appear on the head side due to the increase in pressure (flowing of ink, contamination around the head, ink spreading when resuming printing, etc.) Indeed, it is a great invention to be able to contribute greatly to fundamental prevention and minimization.

본 발명의 프린터의 외부설치용 잉크공급장치에 부설되는 압력자동조절장치는 첨부된 각 도면에 의거 보다 상세히 설명하면 하기와 같다.
Pressure automatic control device attached to the ink supply device for external installation of the printer of the present invention will be described in more detail based on the accompanying drawings.

즉, 본 발명은 프린터 기기의 외부에 일정한 용량의 잉크용기(100)가 설치되고, That is, in the present invention, the ink container 100 having a constant capacity is installed outside the printer device.

상기 잉크용기(100)와 프린터의 내부 헤드(300) 사이에는 잉크공급호스(200)가 구비되며, An ink supply hose 200 is provided between the ink container 100 and the inner head 300 of the printer.

상기 잉크용기(100) 및 잉크공급호스(200)에는 내부 용액의 역류를 방지하기 위한 역류방지장치(180)가 구비되는,The ink container 100 and the ink supply hose 200 is provided with a backflow preventing device 180 to prevent the back flow of the internal solution,

프린터의 외부설치용 잉크공급장치에 부설되는 압력자동조절장치를 구성함에 있어서,
In constructing the pressure automatic control device attached to the ink supply device for external installation of the printer,

상기 역류방지장치(180)와 헤드(300) 사이에 잉크의 압력이 증가되면 잉크 일부를 흡입하여 압력을 풀어주고, When the pressure of the ink is increased between the backflow prevention device 180 and the head 300, the ink is sucked to release the pressure,

압력이 낮아지면 앙크가 자동으로 배출되어 항시 일정한 압력이 유지될 수 있도록 하는 잉크압력 자동조절수단(500)을 추가로 더 구성시켜서 된 것을 그 특징적 요지로 하였다.
When the pressure is lowered, the anch is automatically discharged so that the ink pressure automatic control means 500 is further configured to maintain a constant pressure at all times.

그리고, 상기 잉크압력 자동조절수단(500)은, 잉크가 흡입되면 볼록하게 확장되다가 잉크가 배출되면 납작하게 수축하는 호흡운동(확대/수축)이 아주 자유롭게 얇은 합성수지 필름(비닐)을 진공 밀봉한 진공팩형 압력조절기(510)로 구성하는 것이 바람직하다.In addition, the ink pressure automatic control means 500 is a vacuum in which the synthetic resin film (vinyl) is vacuum-sealed freely with convex expansion (expansion / contraction), which is convexly expanded when the ink is sucked and then contracts flatly when the ink is discharged. Packed pressure regulator 510 is preferably configured.

이때, 상기 진공팩형 압력조절기(510)는 잉크공급호스(200)와 작은 통로(210)로 연결되며, 그 통로(210)는 잉크공급호스(200)와 서로 연통만 되면 족하다.At this time, the vacuum pack-type pressure regulator 510 is connected to the ink supply hose 200 and the small passage 210, the passage 210 is sufficient if only communicate with the ink supply hose 200.

그러나, 헤드(300)가 위치한 방향을 향해 일정한 각도로 경사지게 형성하면, 잉크공급호스(200) 내부로 공급되는 그 잉크의 흐름에 좀더 용이하게 빠져나갈 수 있어보다 바람직할 수 있다.
However, if the head 300 is formed to be inclined at a predetermined angle toward the direction in which the head 300 is located, it may be more preferable to more easily escape the flow of the ink supplied into the ink supply hose 200.

또, 상기 진공팩형 압력조절기(510)는, 상기 역류방지장치(180)와 헤드(300) 사이에 구비하는 잉크공급호스(200)에 구성하여도 되지만, 필요에 따라서는 헤드(300)에 구성시켜도 무방함으로,The vacuum pack pressure regulator 510 may be configured in the ink supply hose 200 provided between the backflow preventing device 180 and the head 300, but may be configured in the head 300 as necessary. You can do it,

위에서 역류방지장치(180)와 헤드(300) 사이라고 명시한 것은, 역류방지장치(180)와 헤드(300) 사이의 잉크공급호스(200)는 물론 헤드까지 포함되는 것은 당연하다.
What is specified above between the backflow prevention device 180 and the head 300, it is natural that the ink supply hose 200 between the backflow prevention device 180 and the head 300, as well as the head.

이하, 상기 잉크압력 자동조절수단(500)의 개념과 그 작용에 대하여 좀더 구체적으로 설명하면,Hereinafter, the concept and operation of the ink pressure automatic control means 500 will be described in more detail.

먼저, 프린터의 인쇄 중에는 헤드(300)에서 분사되는 잉크소모량에 비례하는 잉크량 만큼 보상력에 따라 헤드측으로의 잉크공급이 계속되고,First, during printing of the printer, ink supply to the head side is continued according to the compensating power by the amount of ink proportional to the amount of ink consumed from the head 300,

만약, 인쇄중단의 필요에 따라 헤드측에서 그 잉크의 공급흐름을 차단하면 공급되던 잉크 또한 자동으로 멈추게 되는 것은 당연하다.It is natural that the supplied ink is also automatically stopped if the supply flow of the ink is blocked at the head side in accordance with the necessity of stopping printing.

그러나, 헤드(300)측으로 공급되고 있던 잉크는 최전방의 헤드(300)에서 갑자기 차단하더라도 일시에 모두 정지하는 것이 아니라, 밀려 들어오던 그 잉크의 가속력 때문에 일정한 타임 동안은 계속하여 밀려들다가 그 가속력을 초과하는 압력이 걸리면 그때서야 멈추게 되고,However, even if the ink supplied to the head 300 side is suddenly cut off from the head 300 at the forefront, the ink does not stop all at once. If you get too much pressure then it will stop.

이렇게 압력이 걸리면 일부의 잉크가 뒤로 밀려나면서(역류) 그 압력이 풀리는 것이 통상의 이치지만,It is normal that some of the ink is pushed back (backflow), and the pressure is released when this pressure is applied.

그 후방에는 역류방지용 역류방지장치(180)가 장치되어 있게 때문에 그 역류방지장치(180)와 헤드(300) 사이에는 인쇄가 재게(헤드측에서 분사진행)되기 전까지는 일정한 압력이 계속 걸려 있을 수 밖에 없다.Since the backflow prevention device 180 for preventing backflow is installed at the rear, a constant pressure may be applied between the backflow prevention device 180 and the head 300 until printing is resumed (the separation of lines from the head side). There is nothing else.

역류방지장치(180)와 헤드(300) 사이에 위와 같은 이유로 일정한 압력이 걸리고 그 타임이 길어지거나 횟수가 잦으면, If a constant pressure is applied between the backflow prevention device 180 and the head 300 for the same reason as the above and the time becomes long or the frequency is frequent,

잉크가 헤드(300)측으로 미세하게 삐져나오면서 잉크방울 맺힘현상이 발생하고, 심하면 흘러내려 헤드 주변을 오염시킬 수 있을 뿐만 아니라, As ink splatters finely toward the head 300, ink droplet formation occurs, and if it is severe, it may flow down and contaminate the surroundings of the head.

다시 인쇄가 재기될 때 잉크퍼짐현상이 나타나는 등 다양한 결함이 발생하는 것은 물론, 원하는 정밀한 색상을 구현하기도 어려워 인쇄품질이 크게 저하될 수 있는 데,
When the printing is resumed, various defects such as ink spreading phenomenon occur, and it is difficult to realize the desired precise color, which can greatly reduce the print quality.

이때, 앞서 설명된 바와 같이 역류방지장치(180)와 헤드(300) 사이의 잉크공급호스(200) 또는 헤드 일측에 잉크압력 자동조절수단(500)인 진공팩형 압력조절기(510)를 설치해 두면, At this time, if the vacuum pack-type pressure regulator 510, which is the ink pressure automatic adjusting means 500, is installed on the ink supply hose 200 or one side of the head between the backflow prevention device 180 and the head 300 as described above,

역류방지장치(180)와 헤드(300) 사이에 존재하는 잉크의 압력이 높아질 때는 상기 진공팩형 압력조절기(510) 속으로 잉크의 일부 또는 공기가 흡입(=도피)되어 낮춰지고 인쇄의 재개에 따라 잉크의 공급이 다시 시작되면 자동으로 배출됨으로써 항시 일정한 압력(정상압력)의 유지 및 조절이 가능할 수 있는 것이다.When the pressure of the ink existing between the backflow preventing device 180 and the head 300 is increased, a portion of the ink or air is sucked into the vacuum-pack type pressure regulator 510 (= escape) and lowered as the printing resumes. When the supply of ink is restarted, it is automatically discharged so that it is possible to maintain and adjust a constant pressure (normal pressure) at all times.

따라서, 압력의 상승으로 인해 발생되었던 기존과 같은 결함(잉크맺힘 흘러내림, 헤드오염, 잉크퍼짐 현상 등)방지 및 최소화에 크게 일조할 수 있는 유용한 발명이다.
Therefore, it is a useful invention that can greatly help in preventing and minimizing defects (such as ink bleeding, head contamination, ink spreading phenomenon, etc.) caused by the pressure increase.
