Description
본 발명은 연속공급되는 메디아에 소기하는 인쇄작업을 연속수행하도록 된 디지탈 프린팅 머신(Digital Printing Machine)의 잉크자동공급장치에 관한 것으로, 특히, 헤드로 잉크를 공급하는 보조잉크통의 수위를 감지하여 잉크수용본체의잉크를 보조잉크통으로 자동공급하여 헤드로 잉크가 원활하게 공급될 수 있도록 하고, 보조잉크통으로 잉크수용본체의 잉크가 공급되지 않을 경우에는 작업자에게 경고를 표시하고 출력물을 보존한 상태에서 장치를 일시정지시켜 고가의 출력물과 헤드가 훼손되지 않도록 하여 작업능률을 향상시키도록 하는 디지탈 프린팅머신의 잉크자동공급장치에 관한 것이다.The present invention relates to an automatic ink supplying device of a digital printing machine (Digital Printing Machine) is to perform a continuous printing job to the continuous supply of media, in particular, the ink level by sensing the level of the auxiliary ink supplying ink to the head Automatic supply of ink from the receiving body to the auxiliary ink tank ensures smooth supply of ink to the head.In case the ink from the ink receiving body is not supplied to the auxiliary ink bottle, a warning is given to the operator and the device is preserved while the output is preserved. The present invention relates to an automatic ink supplying device for a digital printing machine, which pauses and stops expensive outputs and heads from being damaged.
일반적으로 디지탈 프린팅 머신(Digital Printing Machine)에서는 마젠타(자주),옐로우(노랑),시안(청록)이라는 삼원색을 사용하여 색을 덧칠하여 여러가지 색상을 창출하는 감산혼합기법을 사용한다.In general, a digital printing machine uses a subtractive blending technique that uses three primary colors of magenta (often), yellow (yellow), and cyan (cyan) to paint colors to create various colors.
상기한 감산혼합기법을 사용하기 위해서는 각각의 색상을 갖는 잉크가 개별적으로 수용되어 각각의 색상을 주사하는 헤드로 공급되도록 하여 각각의 헤드에서 주사되는 색상의 잉크가 덧칠해져 새로운 색이 시현되도록 한다.In order to use the subtraction mixing technique, the ink having each color is individually received and supplied to the head for scanning each color so that the ink of the color scanned from each head is overlaid so that a new color can be displayed.
상기한 바와 같은 디지탈 프린팅머신에서는 각가긔 헤드로 공급되는 잉크가 각각 수용된 잉크수용본체의 잉크의 량이 사용시간이 경과함에 따라 서로 차이가 발생하는 바, 그 이유는 헤드로 공급되는 삼원색의 잉크는 인쇄되는 이미지와 인쇄량에 따라 각 색상의 잉크 사용량에 차이가 발생하게 되기 때문이다.As described above, in the digital printing machine, the amount of ink of the ink receiving body in which the ink supplied to each head is accommodated is different from each other as the use time elapses. The reason is that the three primary colors of ink supplied to the head are printed. This is because a difference in ink usage of each color occurs depending on the image and the printing volume.
즉, 인쇄물의 종류와 혼합색에 따라 삼원색의 잉크 중 어느 하나의 색을 갖는 잉크는 사용량이 많게 되어 잉크통의 잔량이 다른 잉크통에 수용된 다른 색의 잉크보다 적게 되거나 어느 하나의 색을 갖는 잉크의 사용량이 적게 되어 다른 잉크통에 수용된 다른 색의 잉크보다 많게 되어 잉크의 량에 차이를 갖게 된다.That is, depending on the type and mixed color of the printed matter, the ink having any one color of the three primary colors is used more and the remaining amount of the ink bottle is less than the ink of the other color contained in the other ink bottle, or the amount of the ink having one color is less. The amount of ink becomes smaller than that of other colors of ink contained in other ink bottles.
이와 같이 인쇄작업이 계속 진행됨에 따라 어느 색상의 잉크는 다른 색상의잉크보다 먼저 잉크의 부족현상이 발생하게 되고, 이에 따라, 헤드로는 잉크가 공급되지 않아 잉크를 주사할 수 없게 되므로, 출력물에 치명적인 손상을 주는 문제점이 있다.As the printing process continues, ink of a certain color occurs short of ink before ink of a different color, and thus ink cannot be injected because ink is not supplied to the head. There is a fatal damage problem.
이와 같은 문제를 해결하기 위한 종래의 방법으로는 작업자가 수시로 수용본체의 잉크량을 점검해야만 하므로 작업자는 인쇄작업 시 항상 기기주변에 상주해야 하는 불편함이 있었으므로, 이에 따른 작업능률의 저하를 야기시키게 된다.As a conventional method for solving such a problem, the operator has to check the ink level of the receiving body from time to time. Let's go.
한편, 상기한 종래의 기술과는 다르게 잉크가 충진된 카트리지를 사용하게 될 경우에는 수시로 카트리지를 교환해야 하는 불편함과, 폐카트리지의 증가에 따른 환경오염문제와 폐기물처리에 따른 별도의 비용이 발생하며, 카트리지 내부에서 잉크 입자가 일부 응고되는 현상이 발생시에는 이에 대한 대비책이 마련되어 있지 않으므로, 카트리지 자체를 전부 소모하기도 전에 폐기처분해야 하는 비경제적인 사용을 이루는 문제점이 있었다.On the other hand, when using the ink-filled cartridges, unlike the prior art described above, the inconvenience of having to replace the cartridges from time to time, environmental pollution caused by the increase of waste cartridges and extra costs due to waste disposal In addition, when a phenomenon in which the ink particles are partially solidified inside the cartridge does not provide a countermeasure, there is a problem in that the economical use of disposing waste before the cartridge itself is exhausted.
상기한 문제점을 해결하기 위하여 안출된 본 발명은 잉크를 리필(refill)할 수 있도록 하여 폐기물처리의 문제점을 해소하고, 잉크부족 시 단계적으로 작업자에게 이를 알려주도록 함과 동시에 잉크부족 시 잉크의 자동공급과 잉크의 공급이 중단되는 상황에서는 기기를 일시중지시켜 출력물과 헤드의 손상을 방지하도록 하는 목적을 제공한다.The present invention has been made to solve the above problems to solve the problem of waste disposal by refilling the ink, to notify the operator step by step when the ink shortage and at the same time automatic supply of ink In the event that the supply of ink and ink is interrupted, the device is suspended to prevent damage to the printout and the head.

상기한 구성으로 이루어진 본 발명의 작용을 도1내지 도3에서 설명하면 다음과 같다.Referring to the operation of the present invention made of the above configuration in Figures 1 to 3 as follows.
최초, 각 색상별로 마련된 잉크수용본체(104)에 잉크를 충진시키고, 작업자의 초기설정모드 조작에 의하여 각 잉크수용본체(104)에 연결된 솔레노이드펌프(105)가 작동되는 바, 상기 솔레노이드펌프(105)에 의하여 잉크수용본체(104)에 충진된 잉크는 공급관(103)과 연결된 보조잉크통(102)으로 공급되어진다.First, the ink receiving body 104 provided for each color is filled with ink, and the solenoid pump 105 connected to each ink receiving body 104 is operated by an operator's initial setting mode operation. The ink filled in the ink containing body 104 by the () is supplied to the auxiliary ink container 102 connected to the supply pipe 103.
이때, 보조잉크통(102)으로 공급되는 잉크의 수위가 상승하게 되면, 가이드봉(107)에 승하강자유토록 결합된 부유체(110)가 수위의 상승과 동시에 상승하게 되며, 상기 부유체(110)가 상한스토퍼(108)에 접촉되면 상한스토퍼(108)에 내장된 상한접근센서에서 전기신호가 발생하며, 상기 전기신호는 인출선(111)에 의하여 제어부(106)로 전달된다.At this time, when the water level of the ink supplied to the auxiliary ink container 102 rises, the floating body 110 coupled to the guide rod 107 freely up and down rises at the same time as the water level rises, and the floating body 110 ) Contacts the upper limit stopper 108, an electrical signal is generated from the upper limit approach sensor built in the upper limit stopper 108, and the electrical signal is transmitted to the controller 106 by the leader line 111.

Each of the auxiliary ink containers 102 may have different amounts of ink depending on the type of the print job. When the water level is lowered because the amount of ink filled in one auxiliary ink container 102 is high, the float 110 descends at the same time, and at some point, the lower portion of the float 110 contacts the lower limit stopper 109. Accordingly, an electrical signal is generated from the lower limit proximity sensor 113 built in the lower limit stopper 109.
따라서, 상기 전기신호는 인출선(111)을 통하여 제어부(106)로 전달되며, 이때, 제어부(106)는 상기 보조잉크통(102)으로 펌핑하는 솔레노이드펌프(105)에 전원을 인가하여 솔레노이드펌프(105)가 펌핑을 개시하도록 한다.Therefore, the electrical signal is transmitted to the control unit 106 through the leader line 111, in which the control unit 106 applies power to the solenoid pump 105 pumped to the auxiliary ink container 102, the solenoid pump ( 105) to start pumping.
여기서, 상기 솔레노이드펌프(105)가 잉크의 공급을 시작하면, 보조잉크통(102)의 잉크수위는 상승하게 되고, 이에 따라, 부유체(110)가 동시에 상승하게 되며, 상기 부유체(110)가 상한스토퍼(108)에 접촉되면, 상한스토퍼(108)에 내장된 상한근접센서(112)가 전기신호를 제어부(106)로 전달함으로써, 제어부(106)는 솔레노이드펌프(105)에 공급되는 전원을 차단하여 잉크의 공급을 중단시켜, 잉크의 과잉공급을 미연에 방지한다.Here, when the solenoid pump 105 starts supplying ink, the ink level of the auxiliary ink container 102 is increased, and thus, the floating body 110 is raised at the same time, and the floating body 110 is When the upper limit stopper 108 is in contact, the upper limit proximity sensor 112 built in the upper limit stopper 108 transmits an electrical signal to the control unit 106, so that the control unit 106 supplies power supplied to the solenoid pump 105. It cuts off and stops supply of ink, and prevents excessive supply of ink in advance.
한편, 상기 제어부(106)로 전달된 전기신호가 하한근접센서(113)로부터 전달된 전기신호일 경우에는 제어부(106)가 타이머를 작동시키고, 소정시간 동안 상한근접센서(112)로부터 전기신호가 전달되지 않을 경우 경고부(114)로 전원을 인가하여 경고부(114)의 부저를 울리게 한다든다 램프를 점멸시켜 작업자가 잉크수용본체(104)에 잉크가 없음을 알려주어 잉크수용본체(104)에 잉크를 리필(refill)하도록 한다.On the other hand, when the electric signal transmitted to the control unit 106 is an electric signal transmitted from the lower limit proximity sensor 113, the control unit 106 operates a timer, and the electric signal is transmitted from the upper limit proximity sensor 112 for a predetermined time. If not, apply power to the warning unit 114 to sound the buzzer of the warning unit 114. By blinking a lamp, the operator notifies the ink receiving body 104 that there is no ink, and thus to the ink receiving body 104. Refill the ink.
그리고, 상기 경고부(114)가 작동된 후부터 소정시간이 경과한 후에도 상한근접센서(112)로부터 전기신호가 전달되지 않으면, 헤드(115)를 양단 중 어느 하나의 위치로 이송시킨 후, 장치를 일시정지상태에서 대기시키도록 한다.If the electric signal is not transmitted from the upper limit proximity sensor 112 even after a predetermined time has elapsed since the operation of the warning unit 114, the head 115 is moved to one of both ends, and then the device is moved. Wait for pause.
상기한 바와 같이 본 발명은 잉크를 리필시킴으로써, 카트리지의 폐기시 발생하는 부대비용을 절감시킬 수 있음은 물론, 잉크수용본체로부터 보조잉크통으로 잉크를 자동공급할 수 있도록 하고, 잉크수용본체에서 보조잉크통으로 잉크가 공급되지 않으면, 단계적인 경고 후, 기기를 일시정지의 대기상태로 제어하여 고가의 출력물과 헤드가 손상되는 것을 방지하도록 하는 매우 후륭한 발명이다.As described above, the present invention can reduce the associated costs incurred when the cartridge is disposed by refilling the ink, and also automatically supply ink from the ink receiving body to the auxiliary ink container, and from the ink receiving body to the auxiliary ink container. If no ink is supplied, it is a great invention to control the machine to a stand-by state of pause after a step-by-step warning to prevent expensive outputs and heads from being damaged.
