본 발명은 잉크를 이용하여 각종 문서나 사진 등을 프린터 하는 대형 프린터의 잉크공급장치에 관한 것으로서, 더욱 상세하게는 항상 일정분량의 잉크가 공급되어 잉크가 원활하게 프린터의 헤드노즐부로 공급되도록 할 뿐만 아니라, 카트리지의 교체없이 연속적이면서 안정적으로 헤드노즐부에 잉크를 공급할 수 있도록 한 대형 프린터의 잉크공급장치에 관한 것이다.The present invention relates to an ink supply device of a large-format printer for printing various documents or photographs using ink, and more particularly, a certain amount of ink is always supplied so that ink can be smoothly supplied to the head nozzle of the printer. In addition, the present invention relates to an ink supply apparatus of a large printer capable of supplying ink to the head nozzle portion continuously and stably without replacing the cartridge.

최근 산업의 발전으로 인하여 환경미화와 광고의 필요로 인하여 대형실사, 와이드칼라, 대형현수막 등이 널리 사용되면서 이를 컴퓨터 그래픽에 의존하여 보다 화려하고 다양한 디자인으로 출력하는 플로터나 대형 프린터의 수요가 필연적으로 증가하고 있는 실정이다.Recently, due to the development of the industry, due to environmental beautification and the need for advertising, large-scale due diligence, wide color, and large banners are widely used. It is increasing.

이와 같이 종래의 대형 프린터용 잉크공급 장치는 다양한 색상을 공급할 수 있도록 다수개의 다양한 색상의 잉크를 주입시킨 각각의 카트리지를 구비하여 잉크를 분사시키는 헤드노즐부로 필요한 색상과 양의 잉크를 공급시키고 있다.As described above, the conventional ink supply apparatus for large-format printers has respective cartridges injecting a plurality of different colors of ink so as to supply various colors, and supplies ink of a required color and amount to the head nozzle unit for ejecting ink.

그러나 상기와 같은 통상의 잉크공급 장치는 인쇄물을 출력할 때 인쇄물이 대형화일수록 출력도중 카트리지의 잉크가 소진되어 출력을 일시 중지하고 카트리 지를 교체한 다음 다시 인쇄 작업을 진행하여야 하므로 작업시간의 지연과 카트리지 교체로 인한 환경오염과 금전적 손실뿐만 아니라, 인쇄물의 인쇄상태에 영향을 미쳐 인쇄품질에 막대한 지장으로 줌으로써 인쇄물의 품질을 저하시키는 문제점을 수반하고 있다.However, in the conventional ink supply apparatus as described above, when the printed matter becomes larger, the ink of the cartridge runs out during printing as the printout becomes larger, so that the print job must be paused, the cartridge must be replaced, and the print job must be resumed. In addition to environmental pollution and financial loss due to replacement, it affects the printing state of the printed matter, which causes a great obstacle to the print quality is accompanied by a problem of lowering the quality of the printed matter.

이러한 문제점들을 보완하고자 수시로 잉크 투입이 용이하면서 보관이 편리한 일정한 용기에 잉크를 투입시켜서 잉크의 공급이 연속적으로 이루어지도록 하고 있으나, 용기 내의 잉크를 헤드로 공급함에 있어 일정한 압력과 주입량이 유지되도록 하여 잉크의 공급이 원활하게 이루어지도록 하는 센스와 펌프 등을 구성하고 있으며 이를 구동하기 위한 동력과 회로 등을 별도로 설치하여 사용하고 있는 바, 기계적 장치의 추가 설치로 인한 공급 장치의 부피와 무게로 인해 설치가 난해할 뿐만 아니라, 설치비용과 유지비용의 금전적 지출이 추가적으로 발생하여 금전적 공간적인 또 다른 문제점이 추가적으로 발생하고 있는 실정이다.In order to compensate for these problems, the ink is continuously supplied by inserting ink into a certain container which is easy to put ink and easy to store, but in order to supply ink in the container to the head to maintain a constant pressure and injection amount of ink It consists of a sense and a pump to ensure the smooth supply of oil, and it installs power and circuit to drive it separately. It is installed due to the volume and weight of the supply device due to the additional installation of mechanical devices. Not only is it difficult to solve, there are additional financial and spatial problems due to the additional cost of installation and maintenance.

한편, 이를 해결하고자 등록실용신안 제352534호가 안출된 바 있다. 이는 그 등록공고된 공보의 청구범위에 의해 알 수 있듯이, 일정한 크기에 색상이 다른 잉크를 각각 주입시킨 다수개의 잉크용기에 연결호스를 통해서 잉크를 출력용지에 분사시키는 분사노즐이 구성된 헤드로 잉크를 공급하는 통상의 대형프린트용 잉크공급 장치에 있어서, 잉크를 분사시키는 헤드와 분사량과 분사시간을 조절하는 보드로 구성된 분사장치의 내부에, 중앙부에 일정폭의 면적을 유지하는 미세필터를 장착하여 그 하부로는 일정량의 잉크가 확보되는 집수조를 형성하고 상부로는 미세필터에서 걸러진 불순물이 응집되는 응집조를 형성시킨 댐퍼를 구성하여 상하 끝단 면에 연결호스와 헤드를 각각 연결시키는 연결부를 돌출시켜서 연결부를 통해서 잉크용기 내의 잉크가 헤드로 공급되도록 연결시킨 것과, 상기 댐퍼를 중앙부에 일정공간을 유지하는 집수조를 하부가 좁아지는 호퍼형태로 형성하고 그 상부에 안착공과 암나사를 각각 형성하며 집수조 하부에 헤드와 연결이 용이한 연결부를 돌출시킨 집수관을 형성하고, 상부 중심부에 잉크를 이송하여 공급시키는 연결호스와 연결이 용이한 연결부를 돌출시키고 하부 외경에 수나사를 형성하며 중앙에 하부가 개방되는 응집조를 형성시킨 덮개를 형성하여 안착공에 미세필터와 오링을 각각 안착시켜서 집수관의 암나사에 덮개의 수나사를 체결시켜서 구성되어 있다.On the other hand, the utility model registration No. 352534 has been devised to solve this problem. As can be seen from the claims of the registered publication, the head is composed of a jet nozzle for injecting ink onto the output paper through a connection hose to a plurality of ink containers each of which injects ink of different colors in a predetermined size. [0003] A normal large-sized ink supply device for supplying, comprising a fine filter for maintaining an area of a constant width in a central portion of an injector comprising a head for ejecting ink and a board for adjusting the amount of ejection and the ejection time. The lower part forms a collecting tank for securing a certain amount of ink, and the upper part forms a damper that forms an agglomeration tank in which impurities filtered out from the fine filter are formed, and protrudes the connecting portion connecting the connecting hose and the head to the upper and lower ends, respectively. Connected to supply ink in the ink container to the head through the damper; The collection tank to maintain the space is formed in the shape of a hopper narrowing the lower part, and the seating hole and female screw are formed at the upper part thereof, respectively, and the collecting pipe protruding the connection part which is easy to connect with the head is formed at the lower part of the collection tank, and the ink is transferred to the upper center part. The connecting hose to be supplied and the connection part which is easy to connect, and the male screw is formed at the lower outer diameter, and the cover is formed at the center to form a cohesive tank which opens at the lower part. It is configured by fastening the male screw of the cover to the female screw.

따라서, 미세필터의 필터면적을 넓게 구성시킨 댐퍼를 구성시켜서 잉크통의 잉크가 헤드로 주입될 때 일정한 압력으로 공급함과 동시에 잉크 내의 불순물을 걸러주어 장시간 출력에도 잉크 부족 현상에 의한 밴딩(줄생김)현상 등을 예방하여 안정되고 효율적인 인쇄가 용이하도록 함으로서 적은 비용으로 작업성을 향상시키고 자원낭비를 방지하며, 장비의 수명을 연장시키는 등의 다양한 이점을 제공하여 관련업체와 소비자들에게 신뢰성을 보장하는 효과를 기대하고 있다.Therefore, by constructing a damper that has a large filter area of the microfilter, it supplies a constant pressure when the ink in the ink container is injected into the head and filters out impurities in the ink, resulting in banding due to insufficient ink even during long time printing. It guarantees reliability to related companies and consumers by providing various advantages such as improving the workability at a low cost, preventing waste of resources, and extending the life of the equipment by making it easy to print stably and efficiently by preventing the back. Looking forward to it.

그러나, 전술한 종래 프린터 잉크 공급장치는, 그 구성요소가 복잡하여 잉크 공급장치에 의해 프린터의 전체가격에 대한 비용증대가 발생하여 프린터의 구입비용에 적지않은 부담감을 갖게 되는 문제점이 있다.However, the above-described conventional printer ink supply device has a problem in that its components are complicated and the cost increases with respect to the total price of the printer caused by the ink supply device, thereby causing a considerable burden on the purchase cost of the printer.

이외에도 잉크가 수용된 잉크용기의 상측단으로부터 잉크공급호스를 연결하여 잉크용기에 수용된 잉크를 빼내는 잉크공급장치가 사용되고는 있으나, 이와 같이 잉크용기의 상측단에 잉크공급호스를 연결하여 사용할 경우, 잉크용기에 수용된 잉크가 감소함에 따라 발생되는 압력차에 의해 잉크가 제대로 빠져나가지 못하게 되는 문제점이 있다.In addition, an ink supply device for extracting the ink contained in the ink container by connecting the ink supply hose from the upper end of the ink container containing the ink is used.However, when the ink supply hose is connected to the upper end of the ink container, the ink container is used. There is a problem in that the ink is not properly escaped by the pressure difference generated as the ink contained in the decrease.

본 발명은 전술한 종래 프린터의 잉크공급장치가 지닌 문제점을 해결하기 위해 안출된 것으로서, 잉크가 수용된 잉크용기를 거꾸로 뒤집어 자중에 의해 자연스럽게 잉크가 배출되도록 하되, 내부에 스프링과 볼이 내삽된 잉크배출부재를 잉크용기의 입구측에 체결하고 상기 스프링을 밀어올리는 핀이 입설된 잉크수용부재를 더 구비하여 핀에 의해 밀어올려진 볼의 공간으로부터 잉크용기의 잉크가 항상 일정하게 배출되도록 하여 헤드노즐부에 일정량의 잉크가 공급되도록 하고 간단한 구성에 의해 생산단가의 절감을 유도할 수 있으며, 잉크용기에 잉크의 재충전이 용이하도록 한 대형프린터의 잉크공급장치를 제공함에 그 목적이 있다.The present invention has been made to solve the problems with the ink supply device of the conventional printer described above, while the ink is accommodated upside down to the ink is naturally discharged by its own weight, the ink discharged in the spring and the ball interpolated therein Further comprising an ink receiving member in which a member is fastened to the inlet side of the ink container and a pin for pushing up the spring is inserted so that the ink of the ink container is constantly discharged from the space of the ball pushed up by the pin so that the head nozzle portion It is an object of the present invention to provide an ink supply device for a large-sized printer that allows a certain amount of ink to be supplied to the ink container, thereby inducing a reduction in production cost and facilitating refilling of ink in the ink container.

상기와 같이 구성된 본 발명인 대형프린터의 잉크공급장치는, 잉크가 수용된 잉크용기(10)가 거꾸로 뒤집힌 상태에서 잉크용기(10)의 입구측(12)이 연결부재(20)에 장착되어 있고 또한, 상기 잉크용기(10)에 수용된 잉크는 상기 연결부재(20)에 체결된 잉크배출부재(30)에 의해 배출되는 바, 이 때, 상기 잉크배출부재(30)의 연결부(33)에 내삽되어 있는 볼(34)이 밀어올려진 공간에 의해 잉크가 배출됨으로써, 항상 일정량의 잉크가 배출됨이 가능하다.In the ink supply apparatus of the large-size printer of the present invention configured as described above, the inlet side 12 of the ink container 10 is mounted to the connecting member 20 while the ink container 10 containing the ink is turned upside down. The ink contained in the ink container 10 is discharged by the ink discharge member 30 fastened to the connection member 20, at which time, the ink is inserted into the connection portion 33 of the ink discharge member 30. By discharging ink by the space in which the ball 34 is pushed up, it is possible to always discharge a certain amount of ink.

즉, 상기 잉크용기(10)에 수용된 잉크는 상기 잉크용기(10)의 입구측이 체결된 연결부재(20)의 내부로 흘러 배출되게 되고 배출되는 잉크는 상기 연결부재(20)의 제2나사체결부재(23)에 나사체결돌기(31)가 체결된 잉크배출부재(30)의 연결부(33) 내부측으로 배출되게 되며, 또한, 연결부(33)의 내부측으로 배출된 잉크는 다시 상기 연결부(33)의 내부측에 내삽된 볼(34)의 밀어올려진 공간을 통해 상기 잉크배출부재(30)가 인입된 잉크수용부재(40)의 인입부(41)에 모이게 된다.That is, the ink contained in the ink container 10 flows into the inside of the connecting member 20 to which the inlet side of the ink container 10 is fastened, and the discharged ink is the second screw of the connecting member 20. The screw fastening protrusion 31 is fastened to the inside of the connection part 33 of the ink discharge member 30 to which the fastening member 23 is fastened, and the ink discharged to the inside of the connection part 33 is again connected to the connection part 33. The ink discharge member 30 collects in the inlet portion 41 of the ink receiving member 40 through which the ink ejecting member 30 is pushed through the space of the ball 34 inserted into the inner side.

이와 같이 모여진 잉크는 다시 상기 잉크수용부재(40)의 인입부(41) 바닥면 일측에 통공된 호퍼형상의 잉크배출공(44)을 통해 상기 잉크배출공(44)과 일측이 연결되고 타측단은 프린터 헤드노즐부(미도시)와 연결된 연결호스(43)로 흘러 프린터 헤드노즐부에 공급된다.The ink collected in this way is connected to one side of the ink discharge hole 44 through the hopper-shaped ink discharge hole 44 which is formed through the hopper-shaped ink discharge hole 44 of the ink receiving member 40. Flows to the connection hose 43 connected to the print head nozzle part (not shown) and is supplied to the print head nozzle part.

이와 같이 프린터의 헤드노즐부로 공급되는 잉크는, 상기 잉크배출부재(30)의 볼(34)이 밀어올려짐에 따라 형성된 공간에 의해 항상 일정량의 잉크가 공급되기 때문에, 잉크의 공급이 균등적이지 못함에 따라 발생되는 문제점이 해결된다.As such, the ink supplied to the head nozzle portion of the printer is always supplied with a certain amount of ink by the space formed as the ball 34 of the ink discharge member 30 is pushed up, so that the ink supply is not uniform. The problem caused by this is solved.

뿐만 아니라, 상기 잉크배출부재(30)의 연결부(33) 내측에 내삽되어 잉크를 배출하는 공간을 형성하는 볼(34)은 상기 잉크배출부재(30)가 잉크수용부재(40)의 인입부(41)에 인입되어 있을 때만 볼(34)이 핀(42)에 의해 들어올려지게 되어 잉크가 배출되는 공간이 형성되는 것으로, 상기 잉크배출부재(30)를 잉크수용부재(40)로부터 분리할 경우에는 상기 핀(42)에 의해 들어올려진 볼(34)이 원래의 위치로 하강되어 상기 연결부(33)의 내부 바닥면에 형성된 단턱(32)에 의해 막히게 됨으로써 잉크가 더 이상 공급되지 않게 된다.In addition, the ball 34 is inserted into the connecting portion 33 of the ink discharge member 30 to form a space for discharging ink, the ink discharge member 30 is the lead portion of the ink receiving member 40 ( 41, the ball 34 is lifted by the pin 42 only when it is drawn in, so that a space for discharging ink is formed, and the ink discharge member 30 is separated from the ink receiving member 40. The ball 34 lifted by the pin 42 is lowered to its original position and blocked by the step 32 formed on the inner bottom surface of the connecting portion 33 so that ink is no longer supplied.

따라서, 사용자는 프린터를 사용하지 않을 경우에는 상기 잉크수용부재(40)의 상측단 외주연에 형성된 나사체결홈부(46)에 제1나사체결부(22)가 체결된 연결부재(20)를 어느 정도 분리하여 상기 잉크수용부재(40)의 핀(42)이 상기 잉크배출부재(30)의 볼(34)을 밀지 않도록 함으로써 더 이상 잉크가 배출되지 않도록 하면 된다.Accordingly, when the user does not use the printer, the user may use the connecting member 20 in which the first screw fastening portion 22 is fastened to the screw fastening groove 46 formed at the outer circumference of the upper end of the ink receiving member 40. Separation is performed so that the pin 42 of the ink receiving member 40 does not push the ball 34 of the ink discharge member 30 so that no ink can be discharged.

또한, 이와 같이 연결부재(20)를 잉크수용부재(40)로부터 분리하여 잉크배출부재(30)를 통해 더 이상의 잉크가 배출되지 않도록 하여도 상기 잉크수용부재(40)의 인입부(41)에는 일정량의 잉크가 모여 있음에 따라 프린터의 재가동시에 프린터 헤드노즐부에 잉크의 공급이 원활하게 이루어지고, 또한 잉크용기(10)에 수용된 잉크를 다 사용하고 난 후에 잉크용기(10)를 다른 것으로 교체하거나 또는 잉크용기(10)에 새 잉크를 충전하여 사용하고자 할 경우에도 프린터 헤드노즐부로의 잉크공급이 원활하게 이루어진다.In addition, even if the connection member 20 is separated from the ink receiving member 40 so that no further ink is discharged through the ink discharging member 30, the inlet portion 41 of the ink receiving member 40 is provided. As a certain amount of ink is collected, ink is smoothly supplied to the print head nozzle portion when the printer is restarted, and after the ink container 10 is used up, the ink container 10 is replaced with another one. Or even if you want to use a new ink filled in the ink container 10, the ink supply to the printer head nozzle portion is made smoothly.

또한 본 발명에 따르면, 상기 잉크수용부재(40)의 인입부(41) 바닥면 일측에 통공된 잉크배출공(44)의 상단에는 잉크 수용부재(40)에 수용되는 잉크의 불순물을 걸러내는 필터망(45)이 더 안착되어 있음에 따라, 예를 들어 잉크용기(10)에 수용되어 공급되는 잉크에 불순물이 섞여 있더라도 상기 필터망(45)에 의해 걸러짐으로써 프린터 헤드노즐부가 막히거나 고장나거나 하는 등의 악영향이 발생되는 것이 미연에 방지된다.In addition, according to the present invention, a filter for filtering impurities contained in the ink receiving member 40 on the upper end of the ink discharge hole 44 through the one side of the bottom surface of the inlet portion 41 of the ink receiving member 40 As the mesh 45 is further seated, for example, even if impurities are mixed in the ink supplied and supplied to the ink container 10, the print head nozzle portion is blocked or broken by being filtered by the filter mesh 45. It is possible to prevent adverse effects such as

뿐만 아니라, 상기 잉크배출부재(30)의 연결부(33) 하단측 외주연에는 패킹(37)이 더 포설되어 있어 잉크배출부재(30)와 연결부재(20)와의 체결력이 더욱 견고하게 이루어질 수 있으며, 이외에도 본 발명인 대형프린터의 잉크공급장치는 다양하게 변형실시가 가능한 것으로 본 발명의 목적범위를 일탈하지 않는 한, 변형되는 실시예들은 모두 본 발명의 권리범위에 포함되어 해석되어야 한다.In addition, the packing 37 is further provided on the outer periphery of the lower end side of the connection part 33 of the ink discharge member 30, so that the fastening force between the ink discharge member 30 and the connection member 20 can be made more robust. In addition, in addition to the ink supply apparatus of the present invention large-format printer can be modified in various ways, unless the deviation from the object of the present invention, all the embodiments to be modified should be included in the scope of the present invention.

상술한 바와 같이 본 발명인 대형프린터의 잉크공급장치에 의하면, 잉크용기의 입구측이 거꾸로 뒤집힌 상태로 잉크수용부재에 체결되어 있기 때문에 잉크 자중에 의해 잉크가 자연스럽게 배출되어 잉크수용부재의 인입부에 수용되되, 잉크용기의 잉크가 잉크배출부재에 내삽된 볼의 밀어올려진 공간에 의해 배출됨으로써, 항상 일정량의 잉크가 배출될 수 있을 뿐만 아니라 연결부재에 체결된 잉크용기를 교체하거나 또는 잉크용기에 새 잉크를 충전하여 재사용할 수 있음으로써 잉크의 충전이 용이하고 간단한 구성에 의해 생산단가의 절감을 유도할 수 있는 효과가 있다.As described above, according to the ink supply apparatus of the large-sized printer of the present invention, since the inlet side of the ink container is fastened to the ink receiving member in an inverted state, the ink is naturally discharged by the ink weight to be accommodated in the inlet portion of the ink receiving member. However, since the ink in the ink container is discharged by the raised space of the ball inserted into the ink discharge member, a certain amount of ink can always be discharged, as well as replacing the ink container fastened to the connecting member or replacing the ink container with a new one. Since the ink can be recharged and reused, the ink can be easily charged and a simple structure can lead to a reduction in production cost.
