잉크카트리지에의 잉크주입시스템{Ink filling system for ink cartridge with vacuum equipment}Ink filling system for ink cartridges {Ink filling system for ink cartridge with vacuum equipment}

본 발명은 잉크카트리지에 잉크를 주입하는 시스템에 관한 것으로서, 더욱 상세하게는 다량의 잉크가 저장된 서지탱크로부터 일정량의 잉크를 잉크정량공급기로 공급받고 이를 진공상태의 잉크카트리지에 자동으로 주입하는 잉크카트리지에의 잉크주입시스템에 관한 것이다.The present invention relates to a system for injecting ink into an ink cartridge, and more particularly, an ink cartridge for supplying a predetermined amount of ink to an ink quantity supply device from a surge tank in which a large amount of ink is stored and automatically injecting the ink cartridge into a vacuum ink cartridge. To an ink injection system.

잉크젯프린터에 장착하여 사용하는 잉크카트리지(40)의 구성은 도 1에 나타낸 바와 같이 내부에 적어도 하나이상의 잉크저장실(42)이 형성되고 한쪽하단에 잉크프린터의 헤드로 공급하기 위한 공급구(45)가 형성된 몸체(41)와, 이 몸체(41)의 상단에 융착 고정되며 잉크카트리지(40) 내부로 잉크를 주입하는 구멍(44)이 형성된 뚜껑(43)으로 구성된다.As shown in FIG. 1, at least one ink storage chamber 42 is formed inside the ink cartridge 40 to be mounted on the inkjet printer, and a supply port 45 for supplying the ink to the head of the ink printer is provided at one lower end thereof. Is formed of a body 41, and the lid 43 is fusion-fixed to the upper end of the body 41 and formed with a hole 44 for injecting ink into the ink cartridge 40.

상기 잉크카트리지(40)를 이루는 몸체(41)의 잉크저장실(42)에는 잉크를 흡수하여 갖고 있을 수 있는 다공성의 스펀지(46)가 삽입되어 있다. 상기 몸체(41)의 잉크저장실(42)에 삽입되는 스펀지(46)는 프린터제작사의 기종에 따라 선택적으로 삽입하지 않을 수 있다.In the ink storage chamber 42 of the body 41 constituting the ink cartridge 40, a porous sponge 46 may be inserted to absorb ink. The sponge 46 inserted into the ink reservoir 42 of the body 41 may not be selectively inserted according to the model of the printer manufacturer.

상기와 같은 구성을 갖는 종래의 잉크카트리지(40)에 잉크를 주입하는 방법은 도 2에 나타낸 바와 같이 작동실린더(47)를 작동시켜 그 피스톤을 후퇴시키면 서지탱크(10)로부터 일정량의 잉크가 흡입구를 통해 정량용기(48)로 흡입되고 이렇게 정량용기(48)로 흡입된 잉크는 작동실린더(47)가 원위치로 복귀되어 전진되면정량용기(48)의 배출구를 통해 주입헤드(49)로 배출되게 되며 이렇게 주입헤드(49)로 공급된 잉크는 뚜껑(43)의 구멍(44)을 통해 잉크카트리지(40)의 잉크저장실(42)로 주입되어 저장되게 된다.In the conventional method of injecting ink into the ink cartridge 40 having the above-described configuration, as shown in FIG. 2, when the operating cylinder 47 is operated to retract the piston, a predetermined amount of ink is discharged from the surge tank 10. The ink sucked into the metering vessel 48 through the suction container 48 is discharged to the injection head 49 through the outlet of the metering vessel 48 when the working cylinder 47 is returned to its original position and advanced. The ink supplied to the injection head 49 is injected into and stored in the ink storage chamber 42 of the ink cartridge 40 through the hole 44 of the lid 43.

이와 같은 잉크주입방법은 몸체(41)의 잉크저장실(42)에 에어가 가득 차있는 상태(대기와 유통되어 있는 상태)에서 잉크를 주입하기 때문에 상기 잉크가 잉크저장실(42)에 충전되면서 미쳐 빠져나오지 못한 에어가 방울형태로 잉크와 함께 존재하게 된다.Such an ink injection method injects ink into the ink storage chamber 42 of the body 41 in a state where air is full (in a state of being air and circulated), so that the ink is drowned out while being filled in the ink storage chamber 42. Air that does not come out exists with the ink in the form of drops.

그러므로, 이러한 종래 잉크카트리지의 잉크주입방법은 잉크저장실(42)내의 스펀지(46)에 잉크를 분사하듯이 충전하기 때문에 잉크내부에 공기방울이 발생되기 쉽고 이와 같이 공기방울이 생기면 프린터에 장착하여 사용하는 중에 균일한 인쇄가 되지 않거나 중간부분이 불규칙하게 끊기는 등의 인쇄품질이 저하되는 등의 문제점이 있었다.Therefore, since the ink injection method of the conventional ink cartridge fills the sponge 46 in the ink storage chamber 42 as the ink is injected, air bubbles are easily generated in the ink, and when such bubbles are formed, they are mounted on the printer. There was a problem such as poor print quality or poor print quality, such as the middle part is irregularly broken.

이러한 문제점을 최소화하기 위해서는 주입헤드로부터 분사되는 잉크속도를 최대한 저속으로 충전시켜야 했고 이로 인하여 잉크주입의 번거로움은 물론 생산성이 저하되는 원인이 되었다.In order to minimize this problem, it was necessary to fill the ink speed ejected from the injection head as low as possible, which causes the inconvenience of the ink injection and the productivity.

본 발명의 목적은 상기와 같은 문제점을 해소하기 위하여 연구 개발한 것으로서, 잉크카트리지 내부를 진공으로 유지시킨 상태에서 서지탱크로부터 잉크를 공급받아 주입시키므로 잉크카트리지에 일정량의 잉크를 기포 없이 신속하게 주입시킬 수 있는 잉크카트리지에의 잉크주입시스템을 제공하는데 있다.An object of the present invention has been researched and developed in order to solve the above problems, it is possible to quickly inject a certain amount of ink into the ink cartridge without bubbles because the ink is supplied from the surge tank while maintaining the inside of the ink cartridge in a vacuum. It is to provide an ink injection system into an ink cartridge.

또 본 발명의 다른 목적은 잉크카트리지에 잉크를 주입하는 모든 공정이 연속적으로 이루어지게 자동화하여 작업능률 및 생산성 향상을 꾀할 수 있는 잉크카트리지에의 잉크주입시스템을 제공하는데 있다.In addition, another object of the present invention is to provide an ink injection system into an ink cartridge which can be automated to make all the processes of injecting ink into the ink cartridge continuously to improve the work efficiency and productivity.

본 발명의 또 다른 목적은 주입헤드 부위에 잔존하는 이물질 및 잉크카트리지 내부의 에어를 흡입하면서 급속 응축시켜 체적을 최소화시킴으로써 균일한 진공압력으로 유지시킴은 물론 흡입효율의 향상을 꾀할 수 있는 잉크카트리지에의 잉크주입시스템을 제공하는데 있다.Another object of the present invention is to maintain a uniform vacuum pressure by minimizing the volume by rapidly condensing while sucking the foreign matter remaining in the injection head and the air inside the ink cartridge to the ink cartridge that can improve the suction efficiency as well as To provide an ink injection system.

먼저 서지탱크(10) 하부의 잉크공급라인(11)의 개폐밸브(12)를 차단시킨 다음 뚜껑(14)을 열고 서지탱크(10)내에 잉크를 채운다. 이렇게 잉크를 채운 후 시스템을 가동시키면 잉크정량공급기(20)를 이루는 제어기(22)의 베이스 바(22c)와 상한레벨 바(22a)가 서로 도통되지 않기 때문에 잉크공급라인(11)상의 전자밸브(13)를 ON시키므로 잉크정량공급기(20)의 용기(21)로 잉크가 채워지게 된다. 이때, 잉크주입라인(24)상의 전자밸브(25)는 잠겨진 상태이다.First, the on / off valve 12 of the ink supply line 11 below the surge tank 10 is blocked, and then the lid 14 is opened to fill ink in the surge tank 10. When the system is operated after filling the ink in this way, the solenoid valve on the ink supply line 11 is not connected to the base bar 22c and the upper limit level bar 22a of the controller 22 constituting the ink quantity feeder 20. Since 13) is turned on, the ink is filled into the container 21 of the ink quantity supply 20. At this time, the solenoid valve 25 on the ink injection line 24 is in a locked state.

이와 같이 용기(21)로 채워지는 잉크는 상한레벨 바(22a)가 닿을 때까지 잉크가 공급되고 상기 잉크가 상한레벨 바(22a)에 닿으면 베이스 바(22c)와 도통되므로 잉크공급라인(11)상의 전자밸브(13)를 잠그게 된다.In this way, the ink filled with the container 21 is supplied with ink until the upper limit level bar 22a touches the ink, and when the ink touches the upper limit level bar 22a, the ink is connected to the base bar 22c. The solenoid valve 13 on the () is closed.

이러한 상태에서 잉크주입기(30)를 하강시켜 잉크카트리지(40)의 뚜껑(43)의 구멍(44)에 잉크주입기(30)의 노즐(32)이 기밀이 유지되게 안착시키고 진공펌프 (50)를 계속적으로 가동시키면서 흡입라인(51)상의 전자밸브(52)를 개방시키면 흡입라인(51)을 통해 잉크주입기(30) 내부의 이물질은 물론 잉크카트리지(40)의 에어를 흡입하게 된다. 이때, 잉크주입기(30)의 내부에 잔존해 있는 잔존잉크는 잉크주입기(30)의 하단에 마련된 히터(31)로부터 발생되는 열에 의해 기화되게 된다.In this state, the ink injector 30 is lowered, and the nozzle 32 of the ink injector 30 is seated in the hole 44 of the lid 43 of the ink cartridge 40 so that the airtightness is maintained, and the vacuum pump 50 is When the solenoid valve 52 on the suction line 51 is opened while continuously operating, the foreign matter inside the ink injector 30 is sucked through the suction line 51 as well as the air in the ink cartridge 40. At this time, the remaining ink remaining in the ink injector 30 is vaporized by the heat generated from the heater 31 provided at the lower end of the ink injector 30.

이렇게 진공펌프(50)의 흡입력에 의해 잉크주입기(30)의 내부에 잔존하는 기체상태의 잔존잉크와 잉크카트리지(40) 내부의 에어가 흡입라인(51)을 통해 응축기(53)로 흡입되고, 이러한 과정에서 상기 잔존잉크와 에어는 물론 기타 불순물 등이 급속 응축되면서 체적이 최소화되므로 상기 진공펌프(50)를 일정시간 가동시키면 상기 잉크카트리지(40)의 내부를 진공상태로 형성시킬 수 있다.Thus, the remaining ink in the gaseous state remaining in the ink injector 30 and the air in the ink cartridge 40 are sucked into the condenser 53 through the suction line 51 by the suction force of the vacuum pump 50, In this process, the remaining ink and air, as well as other impurities are rapidly condensed to minimize the volume, so that when the vacuum pump 50 is operated for a predetermined time, the inside of the ink cartridge 40 can be formed in a vacuum state.

이와 같이 상기 진공펌프(50)를 일정시간 가동시키면 잉크카트리지(40) 내부의 잉크저장실(42)은 진공상태로 만들어지고 이렇게 잉크카트리지(40) 내부의 잉크저장실(42)이 진공으로 되면 흡입라인(51)상의 전자밸브(52)가 폐쇄된다.As such, when the vacuum pump 50 is operated for a predetermined time, the ink storage chamber 42 inside the ink cartridge 40 is made in a vacuum state, and when the ink storage chamber 42 inside the ink cartridge 40 is in a vacuum, the suction line is vacuumed. The solenoid valve 52 on 51 is closed.

이와 같은 상태에서 잉크주입라인(24)상의 전자밸브(25)를 개방시키면 잉크카트리지(40) 내부가 진공상태이므로 흡입력이 발생시켜 용기(23)내의 잉크가 잉크주입라인(24)과 잉크주입기(30) 및 그 노즐(32)을 통하여 잉크카트리지 (40)내로 주입되기 시작한다.In this state, when the solenoid valve 25 on the ink injection line 24 is opened, the inside of the ink cartridge 40 is in a vacuum state, so suction force is generated so that the ink in the container 23 is transferred to the ink injection line 24 and the ink injector ( 30 and the nozzle 32 begin to be injected into the ink cartridge 40.

상기 잉크카트리지(40)에 주입되는 잉크양은 용기(21)내에 설치된 가장 짧은 길이의 상한레벨 바(22a) 하단에서부터 중간길이의 하한레벨 바(22b) 하단까지의 높이(h)에 해당한다.The amount of ink injected into the ink cartridge 40 corresponds to the height h from the lower end of the upper limit level bar 22a of the shortest length installed in the container 21 to the lower end of the lower limit level bar 22b of the intermediate length.

이와 같이 주입되는 잉크가 하한레벨 바(22b)의 하단이하로 내려가 베이스 바(22c)와 하한레벨 바(22b)가 서로 도통되지 않으면 잉크주입라인(24)상의 전자밸브(25)를 잠그게 된다. 따라서 잉크가 잉크카트리지(40)의 잉크저장실(42)에 용기(21)의 상/하한레벨 바(22a,22b) 사이의 공간에 상응하는 체적만큼만 주입되게 된다.When the ink injected in this way falls below the lower end of the lower limit level bar 22b and the base bar 22c and the lower limit level bar 22b do not conduct with each other, the solenoid valve 25 on the ink injection line 24 is locked. . Therefore, the ink is injected into the ink storage chamber 42 of the ink cartridge 40 only by the volume corresponding to the space between the upper / lower limit level bars 22a and 22b of the container 21.

이와 같이 잉크카트리지(40)에 일정량의 잉크주입이 완료되면 잉크주입기 (30)를 이동 분리시킨 다음 잉크카트리지(40)의 뚜껑(43)의 구멍(44)을 밀폐시켜 출하한다.When the predetermined amount of ink injection is completed in the ink cartridge 40 as described above, the ink injector 30 is moved and separated, and the hole 44 of the lid 43 of the ink cartridge 40 is sealed and shipped.

이와 같이 잉크주입기(30)를 분리시킨 다음 잉크카트리지(40)를 추출하고 다른 잉크카트리지(40)에 잉크주입기(30)를 안착시키는 동안 잉크주입라인(24)상의 전자밸브(25)를 잠금과 동시에 잉크공급라인(11)상의 전자밸브(13)를 개방시켜 잉크정량공급기(20)의 용기(21)로 잉크를 채워넣는다.In this manner, the ink injector 30 is separated, and then the ink cartridge 40 is extracted and the solenoid valve 25 on the ink injection line 24 is locked while the ink injector 30 is seated in the other ink cartridge 40. At the same time, the solenoid valve 13 on the ink supply line 11 is opened to fill the ink into the container 21 of the ink quantity supply 20.

이와 같이 용기(21)로 채워지는 잉크는 상한레벨 바(22a)가 닿을 때까지 잉크가 공급되고 상기 잉크가 상한레벨 바(22a)에 닿으면 베이스 바(22c)와 도통되므로 잉크공급라인(11)상의 전자밸브(13)를 잠그게 된다.In this way, the ink filled with the container 21 is supplied with ink until the upper limit level bar 22a touches the ink, and when the ink touches the upper limit level bar 22a, the ink is connected to the base bar 22c. The solenoid valve 13 on the () is closed.

잉크주입기(30)를 잉크카트리지(40)의 구멍(43)에 안착시킨 이후의 과정은 상기에서 설명한 바와 같은 과정이 연속하여 순차적으로 수행됨으로써 잉크카트리지에의 연속적인 잉크주입이 이루어지게 되는 것이다.After the ink injector 30 is seated in the hole 43 of the ink cartridge 40, the process as described above is carried out sequentially and successively so that continuous ink injection into the ink cartridge is performed.

이상에서 상세하게 설명한 바와 같은 본 발명의 잉크주입시스템은 대기와 유통된 잉크카트리지에 단순히 일정량의 잉크를 피스톤으로 주입하는 종래 기술과는 달리 잉크카트리지 내부를 진공으로 유지시킨 상태에서 서지탱크로부터 잉크를 공급받아 주입시키므로 잉크카트리지에 일정량의 잉크를 기포 없이 신속하게 주입시킬 수 있는 특유의 효과가 있다.As described in detail above, the ink injection system of the present invention is different from the conventional art in which a certain amount of ink is simply injected into a piston into an atmosphere and an ink cartridge distributed therein, and the ink is drawn from the surge tank while the ink cartridge is kept in a vacuum. Since it is supplied and injected, there is a unique effect of rapidly injecting a certain amount of ink into the ink cartridge without bubbles.

또 본 발명은 잉크카트리지에 잉크를 주입하는 모든 공정이 연속적으로 이루어지게 자동화하여 작업능률 및 생산성 향상을 꾀할 수 있는 것이다.In addition, the present invention is to improve the work efficiency and productivity by automating all the process of injecting ink to the ink cartridge to be made continuously.

그리고 본 발명은 주입헤드 부위에 잔존하는 이물질 및 잉크카트리지 내부의 에어를 흡입하면서 급속 응축시켜 체적을 최소화시킴으로써 균일한 진공압력으로 유지시킴은 물론 흡입효율의 향상을 꾀할 수 있는 특유의 효과가 있다.In addition, the present invention has a unique effect of maintaining a uniform vacuum pressure as well as improving suction efficiency by minimizing the volume by rapidly condensing while inhaling the foreign matter remaining in the injection head and the air inside the ink cartridge.
