In particular, the present invention relates to an ink cartridge having an ink drop prevention cap capable of preventing the remaining ink remaining in the discharge port of the cartridge from dropping when the cartridge is taken out after the ink replenishment and / or waste developer recovery operation.

일반적으로, 습식 전자사진방식 인쇄기는 감광벨트와 같은 감광매체에 레이저 빔을 주사하여 정전잠상을 형성하고, 이 정전잠상을 소정 색상을 가지는 분말상의 토너와 용매 역할을 하는 액상의 캐리어가 혼합된 현상액으로 현상하여 인쇄용지에 전사함으로써 원하는 화상을 인쇄한다.In general, a wet electrophotographic printing machine forms an electrostatic latent image by scanning a laser beam on a photosensitive medium such as a photosensitive belt, and the electrostatic latent image is a developer in which a powdery toner having a predetermined color and a liquid carrier serving as a solvent are mixed. The image is developed and transferred onto printing paper to print a desired image.

이러한 습식 전자사진방식 인쇄기에서, 현상액은 도 1에 도시된 바와 같은 현상액 공급장치의 순환탱크(10)에 각 칼라별로 저장되어 있으며, 이 각각의 순환탱크(10)는 배관(11)에 의해 대응하는 현상유니트(100)와 연결되어 있다. 상기 배관(11)에 설치된 현상액펌프(13)가 구동하게 되면, 순환탱크(10)의 현상액이 현상유니트(100)로 공급되게 되며, 이 현상유니트(100)에 의해 감광벨트(110)에 현상액이 분사되게 된다.In such a wet electrophotographic printing press, the developer is stored for each color in the circulation tank 10 of the developer supplying device as shown in FIG. 1, and each of the circulation tanks 10 is corresponded by the pipe 11. It is connected to the developing unit 100. When the developing pump 13 installed in the pipe 11 is driven, the developing solution of the circulation tank 10 is supplied to the developing unit 100, and the developing solution 100 is applied to the photosensitive belt 110 by the developing unit 100. Will be injected.

또한, 상기 각각의 순환탱크(10)는 각 칼라에 해당하는 농축잉크가 저장된 잉크저장탱크(20)로부터 농축잉크를 공급받음과 아울러 캐리어저장탱크(30)로부터 캐리어를 공급받아 적정농도를 유지하도록 되어 있다. 그리고, 상기 순환탱크(10)의 하부에는 순환탱크(10)에서 발생되는 폐현상액을 수거하기 위한 웨이스트탱크(40)가 설치되어 있다. 또한, 현상액 공급장치는 상기 각각의 잉크저장탱크(20) 및 캐리어저장탱크(30)로 농축잉크 또는 캐리어를 리필시킴과 아울러 상기 웨이스트탱크(40)에 수거된 폐현상액을 회수하기 위한 리필장치(50)도 가지고 있다.In addition, each of the circulation tank 10 receives the concentrated ink from the ink storage tank 20 in which the concentrated ink corresponding to each color is stored, and also receives the carrier from the carrier storage tank 30 so as to maintain an appropriate concentration. It is. In addition, a waste tank 40 for collecting waste developer generated in the circulation tank 10 is installed below the circulation tank 10. In addition, the developer supplying device refills the concentrated ink or the carrier into the respective ink storage tanks 20 and the carrier storage tanks 30, and refills the waste developer collected in the waste tank 40. 50)

여기서, 상기한 농축잉크 또는 캐리어는 도 2에 나타낸 바와 같은 잉크 카트리지(60)에 압축공기와 함께 저장되어 있다. 이 잉크 카트리지(60)는 상,하부가 막힌 원통형 카트리지몸체(61)의 중앙부에 노멀 클로우즈 타입의 토출구(62)가 설치된 구조로 되어 있다. 따라서, 상기 토출구(62)를 누르게 되면, 토출구(62)가 개방되면서 카트리지의 내부에 저장되어 있는 농축잉크 또는 캐리어가 급속히 토출되게 된다.Here, the concentrated ink or carrier is stored together with the compressed air in the ink cartridge 60 as shown in FIG. The ink cartridge 60 has a structure in which a normal closing type discharge port 62 is provided at the center of the cylindrical cartridge body 61 with the upper and lower portions blocked. Therefore, when the discharge port 62 is pressed, the concentrated ink or carrier stored in the cartridge is rapidly discharged while the discharge port 62 is opened.

상기 리필장치(50)는 도 3에 나타낸 바와 같이, 잉크 카트리지(60)가 장착되는 공용의 장착부(51)와, 이 장착부(51)의 하부에 회전 및 상하방향으로 이동 가능하게 설치된 밸브유니트(53)를 포함한다. 상기 밸브유니트(53)는 잉크 카트리지(60)의 토출구(62)와 매칭되는 다수의(통상 6개) 밸브(53a)를 구비하고 있다. 이 다수의 밸브(53a) 중, 4개의 밸브는 각각의 잉크저장탱크(20)와, 1개의 밸브는 캐리어저장탱크(30)와, 다른 1개의 밸브는 웨이스트탱크(40)와 배관으로 연결되어 있다.As shown in FIG. 3, the refilling device 50 includes a common mounting portion 51 to which the ink cartridge 60 is mounted, and a valve unit installed below the mounting portion 51 so as to be rotatable and move up and down ( 53). The valve unit 53 is provided with a plurality of (normally six) valves 53a that match the discharge ports 62 of the ink cartridge 60. Of the plurality of valves 53a, four valves are connected to each ink storage tank 20, one valve is connected to the carrier storage tank 30, and the other valve is connected to the waste tank 40 by piping. have.

상기 공용의 장착부(51)에 보충을 요하는 칼라의 잉크가 저장된 잉크 카트리지(60)를 장착하게 되면, 밸브유니트(53)의 해당하는 밸브(53a)가 잉크 카트리지(60)의 토출구(62) 하측에 위치되고, 이어서 밸브유니트(53)가 상승하여 잉크 카트리지(60)의 토출구(62)와 밸브(53a)가 매칭되게 된다. 이 때 농축잉크는 잉크 카트리지 내에 압축공기와 함께 저장되어 있으므로, 압축공기의 압력에 의해 토출되면서 보충을 요하는 탱크로 급속히 공급된다. 이러한 과정으로 보충을 요하는 각각의 잉크저장탱크(20) 및 캐리어저장탱크(30)에 농축잉크 또는 캐리어를 보충할 수 있다.When the ink cartridge 60 in which the ink of the color that needs to be refilled is mounted in the common mounting portion 51, the corresponding valve 53a of the valve unit 53 is discharged from the ink cartridge 60. Located below, the valve unit 53 is raised to match the discharge port 62 of the ink cartridge 60 with the valve 53a. At this time, since the concentrated ink is stored together with the compressed air in the ink cartridge, it is rapidly supplied to the tank requiring refill while being discharged by the pressure of the compressed air. In this process, each of the ink storage tanks 20 and the carrier storage tank 30 that needs to be replenished may be replenished with a concentrated ink or a carrier.

한편, 웨이스트탱크(40)로 수거되는 폐현상액이 증가되어 이를 외부로 회수할 필요가 있는 경우, 공용 장착부(51)에 속이 빈 잉크 카트리지를 장착시키든가 아니면 상기 과정에서 보충이 완료된 속이 비어 있는 잉크 카트리지(60)가 공용 장착부(51)에 장착된 상태에서 웨이스트펌프(41)를 작동시켜, 웨이스트탱크(40)에 저장된 폐현상액을 속이 빈 잉크 카트리지(60)로 펌핑하여 회수한다.On the other hand, when the waste developer collected in the waste tank 40 is increased and needs to be recovered to the outside, the hollow ink cartridge is mounted in the common mounting unit 51 or the hollow ink which has been replenished in the above process. The waste pump 41 is operated by the waste pump 41 in the state where the cartridge 60 is mounted on the common mounting unit 51, and the waste developing solution stored in the waste tank 40 is pumped to the empty ink cartridge 60 for recovery.

그러나, 상기한 바와 같은 습식 전자사진방식 인쇄기의 농축잉크 또는 캐리어 보충 및 폐현상액을 회수하기 위하여 사용되는 종래의 잉크 카트리지는, 토출구(62)가 무방비 상태로 노출되어 있기 때문에, 잉크 보충 및 폐현상액 회수동작 후 카트리지를 인쇄기 본체의 장착부로부터 취출할 때, 토출구(62)에 묻어 있는 미량의 잉크가 떨어져 인쇄기 및 주위 환경을 오염시키는 문제가 있었다. 경우에 따라서는 사용자의 손이나 옷에 잉크가 묻게 되므로, 상기와 같은 잉크 드롭 현상을 방지할 필요가 있다.However, in the conventional ink cartridge used for recovering the concentrated ink or carrier replenishment and waste developer of the above-described wet electrophotographic printing machine, since the discharge port 62 is exposed unprotected, the ink replenishment and waste developer are When the cartridge was taken out from the mounting portion of the printer main body after the recovery operation, there was a problem that a small amount of ink deposited on the discharge port 62 fell and contaminated the printer and the surrounding environment. In some cases, ink is deposited on a user's hand or clothes, so it is necessary to prevent the ink drop phenomenon as described above.

본 발명은 상기와 같은 점을 감안하여 창안된 것으로, 잉크 카트리지를 인쇄기 본체의 장착부에 장착하는 경우에는 토출구가 개방되나 취출하면 토출구를 차단함으로써, 토출구에 묻어 있는 미량의 잉크가 인쇄기나 주변 환경으로 떨어지는 것을 방지할 수 있는 습식 전자사진방식 인쇄기용 잉크 카트리지를 제공하는데 그 목적이 있다.The present invention was conceived in view of the above, and when the ink cartridge is mounted on the mounting portion of the printer main body, the ejection opening is opened, but when ejected, the ejection opening is blocked so that a small amount of ink buried in the ejection opening is transferred to the printer or the surrounding environment. It is an object of the present invention to provide an ink cartridge for a wet electrophotographic printer that can prevent falling.

도시된 바와 같이, 본 발명에 의한 습식 전자사진방식 인쇄기용 잉크 카트리지는, 상,하부가 막힌 밀폐된 원통형상의 카트리지몸체(61)와, 상기 카트리지몸체(61)의 대략 중앙부에 형성되는 토출구(62)와, 상기 토출구(62)를 감싸도록 설치되어 잉크가 무방비 상태로 떨어지는 것을 방지하는 잉크드롭방지캡(63)을 포함한다.As shown, the ink cartridge for a wet electrophotographic printer according to the present invention includes a sealed cylindrical cartridge body 61 having a top and a bottom thereof closed, and a discharge port 62 formed at an approximately center portion of the cartridge body 61. And an ink drop prevention cap 63 installed to surround the discharge port 62 to prevent the ink from falling into a defenseless state.

상기 카트리지몸체(61)의 내부에는 농축잉크 또는 캐리어가 압축공기와 함께 저장되어 있다. 그리고, 상기 토출구(62)는 노멀 클로우즈 타입으로 구성되어 있다. 따라서 정상적인 상태에서 상기 토출구(62)는 닫힌 상태를 유지하므로 카트리지몸체(61)에 저장된 잉크는 토출되지 않는다. 그러나 상기 토출구(62)가 눌려지면, 토출구는 개방되게 되고, 이에 따라 카트리지몸체(61)에 저장된 잉크는 압축공기의 압력에 의해 토출구를 통하여 급속하게 토출되게 된다.The concentrated ink or carrier is stored together with the compressed air in the cartridge body 61. The discharge port 62 is configured of a normal close type. Therefore, in the normal state, the discharge port 62 remains closed, so that the ink stored in the cartridge body 61 is not discharged. However, when the discharge port 62 is pressed, the discharge port is opened, whereby the ink stored in the cartridge body 61 is rapidly discharged through the discharge port by the pressure of the compressed air.

상기 잉크드롭방지캡(63)은 '∪'자 형상으로 형성되며, 자체 탄성력을 가지는 고무 등과 같은 재질로 형성된다. 또한 잉크드롭방지캡(63)은 다수의 슬릿(63a)에 의해 형성되는 다수의 셔터부(63b)를 구비한다. 이 복수의 셔터부(63b)는 도 6에서 보는 바와 같이, 밸브(53a)가 잉크드롭방지캡(63)을 향하여 진입되면, 즉, 도 5에 나타낸 바와 같이, 잉크 카트리지를 카트리지 장착부(51)에 장착시킨 다음 밸브유니트(3)를 상승시키게 되면, 안쪽으로 접히면서 밸브(53a)가 카트리지의 토출구(62)와 매칭되게 한다. 그러나, 카트리지를 장착부(51)로부터 취출하게 되면, 밸브(53a)가 빠지면서 복수의 셔터부(63b)는 자체 탄성에 의해 원래의 위치로 복귀하면서 잉크 카트리지의 토출구(62)를 차단하게 된다. 따라서 토출구(62)에 묻어 있는 잉크가 떨어지더라도 잉크드롭방지캡(63)의 내부에 존재하며 외부로는 유출되지 않는다.The ink drop prevention cap 63 is formed in a '∪' shape, it is formed of a material such as rubber having its own elastic force. In addition, the ink drop prevention cap 63 includes a plurality of shutter portions 63b formed by a plurality of slits 63a. As shown in FIG. 6, when the valve 53a enters the ink drop prevention cap 63, that is, as shown in FIG. 5, the plurality of shutter portions 63b are provided with the cartridge mounting portion 51. As shown in FIG. When the valve unit 3 is raised after being mounted on the valve unit, the valve 53a is matched with the discharge port 62 of the cartridge while being folded inward. However, when the cartridge is taken out from the mounting portion 51, the valve 53a is removed and the plurality of shutter portions 63b block the discharge port 62 of the ink cartridge while returning to the original position by its elasticity. Therefore, even if the ink falling in the discharge port 62 is present inside the ink drop prevention cap 63 and does not flow out.

이와 같이 구성된 본 발명에 의한 잉크 카트리지는, 농축잉크의 보충 및 폐현상액의 회수를 위하여 도 5에서 보는 바와 같이, 인쇄기 본체에 마련된 카트리지 장착부(51)에 장착된다. 그러면, 밸브유니트(53)의 해당하는 밸브(53a)가 카트리지의 토출구(62)와 매칭된 상태에서 상승하는 것에 의해 잉크드롭방지캡(63)의 다수의 셔터부(63b)를 밀어 올리면서 진입하여 밸브(53a)와 잉크 카트리지의 토출구(62)가 매칭되어 잉크 보충 및/또는 폐현상액 회수 동작이 수행된다.The ink cartridge according to the present invention configured as described above is mounted to the cartridge mounting portion 51 provided in the main body of the printer, as shown in FIG. 5 for replenishing the concentrated ink and collecting the waste developer. Then, while the corresponding valve 53a of the valve unit 53 is raised while being matched with the discharge port 62 of the cartridge, the plurality of shutter portions 63b of the ink drop prevention cap 63 are pushed up. Thus, the valve 53a and the discharge port 62 of the ink cartridge are matched to perform ink replenishment and / or waste developer recovery operation.

상기와 같은 잉크 보충 및/또는 폐현상액 회수동작후 잉크 카트리지를 장착부로부터 취출하면, 잉크드롭방지캡(63)의 다수의 셔터부(63b)는 자체 탄성에 의해 원래의 위치로 복귀하게 되고, 따라서 잉크 카트리지의 토출구(62)는 잉크드롭방지캡(63)에 의해 차단되게 된다. 즉, 밸브(53a)가 잉크드롭방지캡(63)에서 빠짐과 동시에 잉크드롭방지캡(63)이 잉크 카트리지의 토출구(62)를 차단하게 되므로, 종래와 같은 잉크 드롭 현상을 방지할 수 있다.If the ink cartridge is taken out from the mounting portion after the above ink replenishment and / or waste developer recovery operation, the plurality of shutter portions 63b of the ink drop prevention cap 63 are returned to their original position by their elasticity. The discharge port 62 of the ink cartridge is blocked by the ink drop prevention cap 63. That is, since the valve 53a is removed from the ink drop prevention cap 63 and the ink drop prevention cap 63 blocks the discharge port 62 of the ink cartridge, it is possible to prevent the ink drop phenomenon as in the prior art.

이상에서 설명한 바와 같은 본 발명에 의하면, 잉크 카트리지의 토출구 주위에 이 토출구를 차단하는 잉크드롭방지캡이 설치되어 있기 때문에, 토출구에 묻어 있는 잉크가 떨어지는 것을 방지할 수 있으며, 따라서 잉크가 인쇄기나 주변 환경으로 떨어짐으로써 야기되는 잉크에 의한 오염 문제를 근본적으로 해소할 수 있다.According to the present invention as described above, since the ink drop prevention cap is provided around the discharge port of the ink cartridge to block the discharge port, it is possible to prevent the ink on the discharge port from falling off, so that the ink can be prevented from falling into the printer or the periphery. It is possible to fundamentally solve the problem of contamination by ink caused by falling into the environment.

또한, 상기와 같은 이유로 사용자의 손이나 옷 등에 잉크가 묻지 않게 되므로, 인쇄기 사용상의 편의를 도모할 수 있다.In addition, since ink does not get on the user's hand or clothes for the same reason as described above, it is possible to facilitate the use of a printing press.

이상에서는 본 발명의 바람직한 실시예에 대하여 도시하고, 또한 설명하였으나, 본 발명은 상기한 실시예에 한정되지 않고, 이하 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 발명이 속하는 분야에서 통상의 지식을 가진자라면 누구든지 다양한 변형 실시가 가능함은 물론이여, 그와 같은 변형은 청구범위 기재의 범위내에 있게 된다.Although the preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the above-described embodiments, and the present invention is not limited to the above-described claims, and is generally used in the art to which the present invention pertains without departing from the gist of the present invention as claimed in the following claims. Anyone skilled in the art can make various modifications, as well as such modifications that fall within the scope of the claims.
