Description

병렬 옵셋 인쇄 장치{PARALLEL-CONNECTED OFFSET PRINTING SYSTEM}Parallel offset printing device {PARALLEL-CONNECTED OFFSET PRINTING SYSTEM}
본 발명은 옵셋 인쇄 장치에 관한 것이다.The present invention relates to an offset printing apparatus.
PDP 등의 평판 디스플레이 장치, 태양전지 등의 전극 패턴 형성 방법은 증착방식, 포토리소그래피 방식, 인쇄방식 등이 있으며, 이 중 제조설비 및 공정이 간편하고 양산성이 우수한 것은 인쇄방식이다.Electrode pattern formation methods such as flat panel display devices such as PDPs and solar cells include a deposition method, a photolithography method, a printing method, etc. Among them, a printing method is a simple manufacturing facility and a process and excellent in mass production.
일반적으로, 인쇄대상물에 인쇄를 하는 방법으로는 인쇄대상물에 인쇄된 필름을 부착시키는 방법, 실크 스크린 인쇄, 그라비아 인쇄, 실사 출력, 옵셋 인쇄 등의 다양한 방법들이 사용되고 있다.In general, as a method of printing on a printed object, various methods such as attaching a printed film to a printed object, silk screen printing, gravure printing, real-time printing, offset printing, and the like are used.
이러한 인쇄 방법중에서 옵셋 인쇄는 트랜스퍼롤(transfer roll)의 표면에 부착되는 고무 또는 실리콘 재질의 블랭킷(blanket)에 의해 패턴롤(pattern roll)의 잉크를 오프(off)하여 인쇄대상물에 잉크를 셋(set)함으로써 인쇄대상물에 원하는 도안이나 문자, 기호 등을 인쇄하게 된다.In such a printing method, offset printing uses a rubber or silicon blanket attached to the surface of a transfer roll to turn off ink on a pattern roll to set ink on a print object. set) prints a desired pattern, character, symbol, or the like on a print object.
종래의 기술에 따른 옵셋 인쇄기를 첨부된 도면을 참조하여 설명하면 다음과 같다.The offset press according to the prior art will be described with reference to the accompanying drawings.
도 1은 종래의 기술에 따른 옵셋 인쇄기를 도시한 개략도이다. 도시된 바와 같이, 종래의 옵셋 인쇄기(110)는 잉크(101)가 묻혀지는 패턴롤(111)과, 패턴롤(111)의 표면에 부착된 잉크(101)가 전이됨과 아울러 고무나 실리콘 그 밖의 합성수지 등의 재질로 이루어진 블랭킷(112)이 감겨짐과 아울러 블랭킷(112)을 종이, 직물, 유리판 등의 인쇄대상물(102)에 밀착시키는 트랜스퍼롤(113)을 포함한다.1 is a schematic diagram showing an offset printing machine according to the prior art. As shown in the drawing, the conventional offset printing machine 110 transfers the pattern roll 111 on which the ink 101 is buried, and the ink 101 attached to the surface of the pattern roll 111, and also transfers rubber or silicon. A blanket 112 made of a material such as a synthetic resin is wound and includes a transfer roll 113 for bringing the blanket 112 into close contact with a print object 102 such as paper, fabric, and glass plate.
패턴롤(111)은 인쇄형상이 도안된 인쇄판(114)이 외주면에 감겨져 있고, 트랜스퍼롤(113)과 접촉하여 회전함으로써 블랭킷(112)으로 잉크를 전달한다.The pattern roll 111 is wound around the outer circumferential surface of the printing plate 114, which is designed for printing, and rotates in contact with the transfer roll 113 to transfer ink to the blanket 112.
트랜스퍼롤(113)은 모터 등과 같은 별도의 회전수단에 의해 회전하거나 인쇄대상물(102)의 이동에 의해 마찰력으로 회전하게 되며, 이로 인해 외주면에 감겨진 블랭킷(112)에 부착된 잉크(101)를 인쇄대상물(102)로 전달함으로써 인쇄대상물(102)에 원하는 도안 등을 인쇄하게 된다.The transfer roll 113 is rotated by a separate rotation means such as a motor, or rotates by frictional force by the movement of the print object 102, which causes the ink 101 attached to the blanket 112 wound on the outer circumferential surface thereof. By transferring to the print object 102, a desired pattern or the like is printed on the print object 102.
옵셋 인쇄로 전극 패턴을 형성할 경우, 선저항 감소를 위해 도포되는 전극이 두터워야 하는데, 아직까지는 1번의 옵셋 인쇄로는 원하는 두께의 전극을 얻을 수 없어 수회 반복하여 적층 인쇄함으로써 전극의 두께 및 우수한 종횡비를 실현하고 있다. 이러한 이유로 실크스크린 인쇄방법에 비하여 양산성이 떨어지는 문제점이 있다.When the electrode pattern is formed by offset printing, the electrode applied to reduce the line resistance should be thick. Until now, the electrode of the desired thickness cannot be obtained by one offset printing. The aspect ratio is realized. For this reason, there is a problem in that mass productivity is inferior to that of silk screen printing.
옵셋 인쇄의 양산성 문제를 해결하기 위한 하나의 방식으로서, 본 발명자는 도 2의 직렬 인라인(in-line) 방식을 고려하였다. 본 방식은 옵셋 공법을 이용하여 태양전지 등의 인쇄대상물의 상면에 패턴을 연속 인쇄하는 것으로, 크게 인쇄대상물 로딩 구간과 인쇄대상물에 패턴을 프린팅하는 구간으로 나누어지며, 구체적으로는 캐리어 로더(120), 인쇄대상물 투입용 트리폿(Tripod) 유닛(121), 인쇄대상물 투입용 2축 로봇(122), 직렬 인라인 방식으로 정렬된 다수의 옵셋 인쇄기(110), 플레이트 컨베이어(130) 등으로 구성된다. 인쇄대상물의 인쇄와 이송은 서보모터의 동기화로 인쇄대상물에 패턴을 인쇄하게 된다.As one way to solve the mass productivity problem of offset printing, the inventors considered the serial in-line method of FIG. The present method is to continuously print the pattern on the upper surface of the printing object such as solar cell using the offset method, it is divided into the printing object loading section and the printing section of the pattern on the printing object, specifically, the carrier loader 120 , A tripod unit 121 for inserting a print object, a two-axis robot 122 for inserting a print object, a plurality of offset printers 110 arranged in a series inline manner, a plate conveyor 130, and the like. Printing and conveying of the printed object will print the pattern on the printed object by synchronizing the servomotor.
상기 구성의 직렬 인라인 방식은, 요구되는 옵셋 인쇄 반복 회수만큼 옵셋 인쇄기를 직렬로 위치시켜 인라인 상태에서 연속적으로 인쇄함으로써 실크스크린과 동등 수준의 양산성을 얻을 수 있을 것으로 기대하였다.In the serial inline method of the above configuration, it was expected that mass productivity equivalent to that of silkscreen could be obtained by continuously printing in an inline state by placing an offset printer in series as many times as required offset printing repetitions.
그러나, 직렬 인라인 방식은 상용화가 용이치 않은 것으로 드러났다. 가장 큰 이유로서, 전극 패턴의 얼라인 문제를 들 수 있다. 옵셋 인쇄의 경우 동일한 패턴을 수회 반복 인쇄하여 적층하여야 하므로 직렬 인라인 방식의 각 옵셋 인쇄기는 동일한 위치에 패턴을 전사하여야 한다. 이를 위해서는 첫째, 각 옵셋 인쇄기의 패턴롤에 형성된 패턴이 정확하게 일치하여야 하고, 둘째, 패턴롤의 얼라인이 정확하게 일치하여야 하고, 셋째, 각 옵셋 인쇄기의 직렬 인라인 배열이 x, y축 모두 정확히 일치하여야 하고, 넷째, 인쇄대상물에 패턴을 전사하는 타이밍이 정확히 일치하여야 하고, 다섯째, 이동 컨베이어 상에 놓여지는 인쇄대상물의 위치가 컨베이어 이동중이나 인쇄과정 등에서 틀어지지 않고 항상 고정적으로 유지되어야 한다.However, the serial inline method has proved to be not easy to commercialize. The biggest reason is the alignment problem of an electrode pattern. In the case of offset printing, the same pattern must be repeatedly printed several times, and thus, each offset printing machine of the serial inline method must transfer the pattern to the same position. To do this, first, the patterns formed on the pattern rolls of each offset press must match exactly. Second, the alignment of the pattern rolls must match exactly. Third, the serial inline array of each offset press must match both the x and y axes. Fourth, the timing of transferring the pattern to the print object must be exactly the same. Fifth, the position of the print object placed on the moving conveyor must be kept fixed at all times without moving during the conveyor movement or printing process.
옵셋 인쇄로 전극 패턴을 형성하는 가장 큰 이유는 60㎛ 이하의 미세 선폭의 구현이 가능하다는 것이다. 상기 전극 패턴 얼라인 변수 중 어느 하나라도 어긋나게 되면 옵셋 인쇄의 가장 큰 장점인 미세 선폭 구현이 어려워지는데, 별도의 정밀 얼라인 장비나 수단을 구비하지 않고서는 상기 모든 변수를 정확하게 제어하는 것은 사실상 매우 어렵다.The biggest reason for forming an electrode pattern by offset printing is that it is possible to realize a fine line width of 60 μm or less. If any of the electrode pattern alignment parameters are misaligned, it becomes difficult to realize fine line width, which is the biggest advantage of offset printing, and it is very difficult to precisely control all the variables without any separate precision alignment equipment or means. .
또한, 소모품인 블랭킷을 교체하는 작업을 할 때마다 모든 얼라인을 재점검해야하는 문제가 있는데, 이러한 작업은 양산성에서 많은 양보를 요구하게 된다.In addition, there is a problem that every alignment needs to be rechecked every time the blanket, which is a consumable, is replaced, which requires a lot of concessions in mass production.
또한, 옵셋 인쇄기 어느 하나가 고장이 나거나 문제가 생기면 이를 해결할 때까지 라인 전체가 가동이 중단되는 문제점이 있다. In addition, if any one of the offset press is broken or has a problem there is a problem that the entire line is stopped until it is solved.
본 발명은 상기의 문제점을 해결하기 위한 것으로서, 복잡하고 어려운 패턴 얼라인 문제를 원천적으로 해결할 뿐만 아니라 옵셋 공정의 미세선폭 구현이라는 장점을 손상시키지 않으면서, 양산성에서도 장점을 지니고, 유지 보수에 있어서도 획기적인 옵셋 인쇄 장치를 제공하는 것을 목적으로 한다. The present invention is to solve the above problems, not only solve the complex and difficult pattern alignment problem at the source, but also has advantages in mass production, without compromising the advantages of the implementation of the fine line width of the offset process, and also in maintenance It is an object to provide a breakthrough offset printing apparatus.

본 발명은 또한, 다수의 옵셋 인쇄기가 로딩 컨베이어의 측면에 병렬적으로 위치하여 로딩 컨베이어 상의 인쇄대상물이 옵셋 인쇄기에 공급되어 인쇄되는 병렬 옵셋 인쇄장치로서, 상기 옵셋 인쇄기를 포함한 일영역의 구성품이 하나의 옵셋 인쇄 세트를 이루어 병렬 옵셋 인쇄장치에 조립되거나 탈착이 가능한 것을 특징으로 하는 병렬 옵셋 인쇄장치를 제공한다.The present invention also provides a parallel offset printing apparatus in which a plurality of offset printing machines are located in parallel with the side of the loading conveyor, and the object to be printed on the loading conveyor is supplied to the offset printing machine for printing. It provides a parallel offset printing apparatus characterized in that the assembly of the offset printing set to be assembled or detachable to the parallel offset printing apparatus.
상기의 구성적 특징을 갖는 본 발명은 복잡하고 어려운 패턴 얼라인 문제를 원천적으로 해결할 뿐만 아니라 옵셋 공정의 미세선폭 구현이라는 장점을 손상시키지 않으면서, 양산성에서도 장점을 지니고, 유지 보수에 있어서도 획기적인 옵셋 인쇄 장치를 제공할 수 있다.The present invention having the above constitutive features not only solves the complicated and difficult pattern alignment problem at the source but also has advantages in mass production without compromising the advantages of implementing the fine line width of the offset process, and also provides a significant offset in maintenance. A printing apparatus can be provided.
구체적으로, 옵셋 인쇄기를 인라인 공정에서 다수개를 병렬로 연결함으로써 옵셋 인쇄기의 단점인 수회 적층 인쇄로 인한 택트 타임의 과도한 증가, 양산성 감소를 상쇄시킬 수 있다.In detail, by connecting a plurality of offset presses in parallel in an inline process, an excessive increase in tact time and a decrease in mass productivity due to several stacking printings, which is a disadvantage of an offset press, may be offset.
또한, 옵셋 인쇄기가 독립적으로 병렬 연결되고 하나의 인쇄대상물은 하나의 옵셋 인쇄기에서 수회 적층 인쇄되어 마무리되기 때문에 전술한 직렬 연결에 따른 얼라인 문제를 해소할 수 있다.In addition, since the offset presses are independently connected in parallel and one printed object is laminated and finished several times in one offset press, the alignment problem according to the serial connection described above can be solved.
또한, 병렬적 연결이므로 어느 하나의 옵셋 인쇄기가 고장이 나거나 에러가 발생하여도 다른 옵셋 인쇄기에 영향을 미치지 않아 생산 라인의 전체 중단이 일어나지 않는다. 이는 전기 회로에서 직렬 연결의 단선은 전체 회로의 전류 흐름을 중단시키지만, 병렬 연결에서 일부의 단선은 전체 회로의 전류 흐름을 중단시키지 않는 것에 비유할 수 있다.In addition, because of the parallel connection, if one offset press fails or an error does not affect the other offset presses, there is no overall interruption of the production line. This can be likened that in an electrical circuit, the disconnection of the series connection interrupts the current flow of the entire circuit, while in parallel connection some disconnection does not interrupt the current flow of the entire circuit.
또한, 블랭킷의 교체, 옵셋 인쇄기의 보수 등은 생산 라인의 가동 중에서 개별적으로 이루어지면 되므로 유지 보수에 있어서도 획기적이다.In addition, replacement of the blanket, maintenance of the offset press, and the like need to be made separately during operation of the production line, which is also remarkable in maintenance.

이하에서는 도면 및 실시예를 통하여 본 발명을 보다 상세히 설명하기로 한다. 하기의 설명은 본 발명의 구체적 일례에 대한 것이므로, 비록 단정적, 한정적 표현이 있더라도 특허청구범위로부터 정해지는 권리범위를 제한하는 것은 아니다.Hereinafter, the present invention will be described in more detail with reference to the drawings and embodiments. The following descriptions are for specific examples of the present invention, but are not intended to limit the scope of the rights set forth in the claims, even if there is an assertive or limited expression.
도 3은 본 발명의 일실시예에 따른 병렬 옵셋 인쇄장치로서, 인쇄대상물을 운반하는 로딩 컨베이어(21a, 21b), 상기 로딩 컨베이어(21a, 21b)에 인쇄대상물을 적정 시간에 공급하는 캐리어 리프터(20), 상기 로딩 컨베이어의 측면에 병렬적으로 위치하는 다수의 옵셋 인쇄기(10), 상기 로딩 컨베이어(21a, 21b) 상의 인쇄대상물을 옵셋 인쇄기(10)에 공급하는 인쇄대상물 공급부재(40), 및 옵셋 인쇄기(10)에서 인쇄된 인쇄완성품을 운반하는 언로딩 컨베이어(22)를 포함하여 이루어진 것을 특징으로 한다.3 is a parallel offset printing apparatus according to an embodiment of the present invention, which includes a loading conveyor 21a and 21b for carrying a printing object and a carrier lifter for supplying a printing object to the loading conveyor 21a and 21b at an appropriate time. 20), a plurality of offset printers (10) positioned in parallel to the side of the loading conveyor, a printing object supply member (40) for supplying a printing object on the loading conveyor (21a, 21b) to the offset printing machine (10), And an unloading conveyor 22 for carrying the printed finished product printed by the offset printer 10.
본 발명의 일실시예에 따른 병렬 옵셋 인쇄장치는 옵셋 인쇄기(10)를 인라인 공정에서 다수개를 병렬로 연결함으로써 옵셋 인쇄기의 단점인 수회 적층 인쇄로 인한 택트 타임의 과도한 증가, 양산성 감소를 상쇄시킬 수 있으며 옵셋 인쇄기(10)가 독립적으로 병렬 연결되고 하나의 인쇄대상물은 하나의 옵셋 인쇄기(10)에서 수회 적층 인쇄되어 마무리되기 때문에 전술한 직렬 연결에 따른 얼라인 문제를 해소할 수 있다.The parallel offset printing apparatus according to an embodiment of the present invention offsets an excessive increase in tact time and a decrease in mass productivity due to the multi-layer printing, which is a disadvantage of an offset printing machine, by connecting a plurality of offset printers 10 in an inline process in parallel. Since the offset printer 10 is independently connected in parallel and one print object is laminated and finished several times in one offset printer 10, the alignment problem according to the serial connection described above can be solved.
캐리어 리프터(20)는 로딩 컨베이어(21a, 21b)에 인쇄대상물을 적정 시간에 공급하는 역할을 한다. 정확한 시간에 인쇄대상물을 로딩 컨베이어(21a, 21b)에 로딩하기 위한 구동, 제어 방법은 다양할 수 있으며 제한되지 않는다. 바람직하기로는 서보모터를 이용하여 정밀하게 제어하는 것이 좋다. 인쇄대상물의 로딩은 옵셋 인쇄기(10)의 대수 및 위치간격, 적층 인쇄에 걸리는 시간 등을 고려하여 제어된다.The carrier lifter 20 serves to supply the print object to the loading conveyors 21a and 21b at an appropriate time. The driving and controlling method for loading the printed object on the loading conveyors 21a and 21b at the correct time may vary and is not limited. Preferably, the servo motor is used for precise control. The loading of the print object is controlled in consideration of the number and position intervals of the offset printer 10, the time taken for the laminated printing, and the like.
로딩 컨베이어(21a, 21b)는 연속적으로 또는 일시적 불연속식으로 옵셋 인쇄기(10) 근처로 인쇄대상물을 전달하는 기능을 한다. 로딩 컨베이어(21a, 21b)는 벨트식, 나사식, 버킷식, 플레이트식, 공기식, 체인식, 롤러식, 트롤리식 등 제한되지 않는다. 바람직하기로는 로딩 컨베이어(21a, 21b) 상에서 인쇄가 이루어지는 것이 아니므로 간편한 벨트식이 좋다. 직렬 방식의 경우에는 컨베이어 상에서 인쇄가 이루어지므로 소프트한 벨트 방식의 컨베이어를 취하기에는 제약이 따른다. 이 또한 병렬 방식의 장점이 된다. The loading conveyors 21a and 21b serve to transfer the print object near the offset printing machine 10 continuously or temporarily discontinuously. The loading conveyors 21a and 21b are not limited to belt type, screw type, bucket type, plate type, air type, chain type, roller type, trolley type, and the like. Preferably, since the printing is not performed on the loading conveyors 21a and 21b, a simple belt type is preferable. In the case of the tandem type, the printing is done on the conveyor, so there is a limitation in taking a soft belt type conveyor. This is also an advantage of the parallel approach.
옵셋 인쇄기(10)는 다수개가 위치하되, 로딩 컨베이어의 측면에 병렬적으로 위치하게 된다. 도 3에 도시된 바와 같이, 다수의 옵셋 인쇄기(10)는 로딩 컨베이어의 일측면에 편중되어 위치할 수 있다. 또는 도 4에 도시된 바와 같이, 다수의 옵셋 인쇄기(10)는 로딩 컨베이어의 양측면에 위치할 수 있다. 이러한 다양한 조합이 가능한 것도 직렬 방식과 차별되는 특징이다. 옵셋 인쇄 장치를 설치할 공간이 정사각형에 가깝다면 로딩 컨베이어의 양측면에 옵셋 인쇄기(10)를 위치시키는 방법이 좋다. 반면, 공간이 길쭉한 직사각형이라면 로딩 컨베이어의 일측면에 편중되게 옵셋 인쇄기(10)를 위치시키는 방법이 선호된다. 병렬 방식은 설비 공간 맞춤형으로 다양하게 조합이 가능한 것이 장점이다.A plurality of offset printing presses 10 are located in parallel with the side of the loading conveyor. As shown in FIG. 3, the plurality of offset printing presses 10 may be located biased on one side of the loading conveyor. Alternatively, as shown in FIG. 4, the plurality of offset printing presses 10 may be located at both sides of the loading conveyor. Such various combinations are distinguishable from the serial method. If the space in which the offset printing apparatus is to be installed is close to a square, a method of positioning the offset printing presses 10 on both sides of the loading conveyor is preferable. On the other hand, if the space is an elongated rectangle, the method of positioning the offset printing machine 10 in a biased manner on one side of the loading conveyor is preferred. The parallel method is advantageous in that various combinations can be made to customize the installation space.
또한, 도 5 및 도 6에 도시된 바와 같이 상기 옵셋 인쇄기(10)에는 인쇄대상물(11)이 다수개씩 공급되어 다수개가 동시에 인쇄될 수 있다. 바람직하기로는 2~100개가 공급되어 동시에 인쇄될 수 있다. 도면과 이하의 설명은 2개 공급을 예로 든다. 인쇄대상물(11)이 2개씩 공급되는 경우, 인쇄대상물(11)을 인쇄대상물(11) 고정부재에 가로로 정렬, 고정하여 인쇄할 수도 있으며(도 5), 세로로 정렬, 고정하여 인쇄할 수도 있다(도 6). 병렬 방식에서는 하나의 블랭킷롤에 2개의 패턴 인쇄가 가능하므로 2개 동시 인쇄가 가능하다. 그러나 직렬 방식에서는 패턴 얼라인 문제 때문에 블랭킷롤 제작시 그 크기가 제한적이어서 2개의 패턴 인쇄가 어렵다. 여기서 병렬 방식의 또 하나의 장점이 도출된다.5 and 6, a plurality of print objects 11 may be supplied to the offset printer 10 so that a plurality of print objects 11 may be printed at the same time. Preferably 2 to 100 can be supplied and printed at the same time. The drawings and the following description take two feeds as an example. When the print objects 11 are supplied two by two, the print objects 11 may be horizontally aligned and fixed to the print object 11 fixing member to be printed (FIG. 5), or may be printed vertically aligned and fixed. (FIG. 6). In parallel, two patterns can be printed on one blanket roll, so two simultaneous prints are possible. However, in the serial method, the size of the blanket roll is limited due to the pattern alignment problem, so it is difficult to print two patterns. Here is another advantage of the parallel approach.
상기 옵셋 인쇄기(10)는 일반적으로 인쇄대상물(11) 고정부재에 인쇄대상물(11)을 고정한 후 인쇄대상물(11)이 이동하면서 인쇄되게 된다. 인쇄대상물 고정부재(30)는 인쇄를 위해 동작하는 플레이트에 구성되거나 플레이트 자체로서, 제한되지 않으나 진공흡입에 의해 인쇄대상물을 고정시키는 석션 테이블(suction tabel)인 것이 좋다. 병렬 옵셋 인쇄 장치는 고정부재 상의 인쇄대상물을 옵셋 인쇄기(10)의 블랭킷롤에 간편하게 자동 정렬하는 것으로 얼라인 문제는 해결된다.The offset printer 10 is generally fixed to the printing object 11 to the printing object 11 fixed member to be printed while the print object 11 is moved. The printing object fixing member 30 is formed on a plate operating for printing or the plate itself, but is not limited but may be a suction table (suction tabel) for fixing the printing object by vacuum suction. The parallel offset printing apparatus solves the alignment problem by automatically aligning the printing object on the fixing member with the blanket roll of the offset printing machine 10.
인쇄대상물 공급부재(40)는 로딩 컨베이어(21a, 21b) 상의 인쇄대상물을 옵셋 인쇄기(10)에 공급하는 기능을 수행한다. 도 3에 도시된 바와 같이, 자동 제어에 의해 인쇄대상물 공급부재(40)가 로딩 컨베이어(21a, 21b) 상에서 이동하는 인쇄대상물을 픽업하여 인쇄대상물 고정부재(30)로 운송하게 된다. 인쇄대상물 공급부재(40)는 이러한 픽업장치로만 한정하는 것은 아니고, 별도의 컨베이어를 사용하여 인쇄대상물을 옵셋 인쇄기(10)에 공급할 수도 있으며 제한되지 않는다.The print object supply member 40 performs a function of supplying a print object on the loading conveyors 21a and 21b to the offset printer 10. As shown in FIG. 3, the print object supply member 40 picks up the print object moving on the loading conveyors 21a and 21b by automatic control and transports it to the print object fixing member 30. The print object supply member 40 is not limited to such a pickup device, and may supply a print object to the offset printer 10 using a separate conveyor, but is not limited thereto.
한편, 인쇄대상물 공급부재(40)는 옵셋 인쇄기(10)로부터 인쇄된 인쇄완성품을 취출하는 기능을 더 수행할 수 있다. 즉, 인쇄완성품을 언로딩 컨베이어(22)로 이동시키는 기능을 겸할 수 있다.Meanwhile, the print object supply member 40 may further perform a function of taking out the printed finished product from the offset printer 10. That is, it can serve as a function of moving the printed finished product to the unloading conveyor 22.
언로딩 컨베이어(22)는 옵셋 인쇄기(10)에서 인쇄되어 취출된 인쇄완성품을 다음의 후공정, 예를 들어 건조 및 열처리 공정으로 운반하는 기능을 수행한다. 언로딩 컨베이어(22)의 방식은 제한되지 않으며, 전술한 로딩 컨베이어(21a, 21b) 방식을 따를 수 있다. 언로딩 컨베이어(22)의 위치는 도 3에서 예시된 것에 제한되지 않으며 다양할 수 있으며, 때로는 옵셋 인쇄기(10)의 후면(로딩 컨베이어(21a, 21b)의 반대편)에 위치할 수 있다. 이 경우 별도로 인쇄완성품을 언로딩 컨베이어(22)로 이동시키는 수단을 마련할 수도 있으나, 옵셋 인쇄기(10)에서 바로 언로딩 컨베이어(22)로 인쇄완성품을 배출할 수도 있다.The unloading conveyor 22 performs a function of conveying the printed finished product printed and taken out by the offset printing machine 10 in the following post process, for example, drying and heat treatment process. The manner of the unloading conveyor 22 is not limited and may follow the manner of the above-described loading conveyors 21a and 21b. The location of the unloading conveyor 22 is not limited to that illustrated in FIG. 3 and may vary, and may sometimes be located on the rear side of the offset press 10 (opposite to the loading conveyors 21a, 21b). In this case, a means for moving the printed product to the unloading conveyor 22 may be separately provided, but the printed product may be discharged directly from the offset printing machine 10 to the unloading conveyor 22.
언로딩 컨베이어(22) 상의 인쇄 완성품은 다음 공정을 위해 개별적, 또는 복수로 취합될 수 있으며, 이를 위해 인쇄완성품 취출부재(50)를 더 포함할 수도 있다. 인쇄완성품 취출부재(50)는 언로딩 컨베이어(22)의 끝단에 위치하는 것이 좋다.The finished printed product on the unloading conveyor 22 may be collected individually or in plurality for the next process, and may further include a printed product takeout member 50 for this purpose. Printed article taking out member 50 is preferably located at the end of the unloading conveyor (22).
도 3에 도시된 본 발명의 일례인 병렬 옵셋 인쇄장치로 옵셋 인쇄를 5번 반복하여 기판에 전극 패턴을 형성한 결과, 인쇄완성품 택트 타임(Tack time)이 5 sec/EA 이내, 좋기로는 약 3.5 sec/EA이내로서, 기존의 옵셋 인쇄장치로 인쇄할 경우의 35 sec/EA에 비하여 비약적으로 향상된 효과를 얻었으며, 충분한 양산성을 갖는 것으로 입증되었다.As a result of forming an electrode pattern on a substrate by repeating offset printing five times with a parallel offset printing apparatus, which is an example of the present invention shown in FIG. 3, the printed finished product's tack time is within 5 sec / EA, preferably about Within 3.5 sec / EA, a significant improvement was obtained compared to 35 sec / EA when printing with a conventional offset printing apparatus, and proved to have sufficient mass productivity.
상기 인쇄대상물은 전극 형성을 위한 PDP 패널 기판일 수 있으며, 특히 태양전지 기판 등일 수 있다. 태양전지 기판의 경우 전면의 핑거 전극 또는/및 버스바 전극의 미세 패턴 형성을 위해 본 발명의 병렬 옵셋 인쇄장치가 바람직하게 사용될 수 있다. The printed object may be a PDP panel substrate for forming an electrode, and in particular, may be a solar cell substrate. In the case of a solar cell substrate, the parallel offset printing apparatus of the present invention may be preferably used to form a fine pattern of a finger electrode and / or busbar electrode on the front surface.
도 7은 본 발명의 구성적 특징을 나타내는 도로서, 상기 다수의 옵셋 인쇄기(10) 중 어느 하나(점선의 네모박스)가 가동이 중단되거나 에러가 발생하여도 다른 옵셋 인쇄기(10)는 정상적으로 가동, 인쇄되는 독립 방식인 것을 특징으로 한다. 즉, 로딩 컨베이어(21a, 21b)는 지속적으로 인쇄대상물을 전송하므로 중간에 옵셋 인쇄기(10)가 문제가 발생하여도 그 다음에 위치하는 옵셋 인쇄기(10)에 인쇄대상물을 안정적으로 전달할 수 있다. 로딩 컨베이어(21a, 21b)에서 직접 인쇄하는 것이 아닌 병렬 연결된 옵셋 인쇄기내에서 인쇄가 이루어지므로 로딩 컨베이어(21a, 21b)를 멈출 이유가 없다. 가동이 중단된 해당 옵셋 인쇄기에는 인쇄대상물이 공급되지 않도록 캐리어 리프터(20)의 인쇄대상물의 로딩을 제어하면 되는 것이다. 이는 전기 회로의 병렬 연결에서 일부의 단선은 전체 회로의 전류 흐름을 중단시키지 않는 것과 유사하다. FIG. 7 is a diagram illustrating a structural feature of the present invention. Even if any one of the plurality of offset printers 10 (dotted square boxes) is stopped or an error occurs, the other offset printers 10 operate normally. It is characterized in that the independent printing method. That is, since the loading conveyors 21a and 21b continuously transmit the print objects, the print objects can be stably delivered to the offset print machine 10 positioned next to the offset printer 10 even if a problem occurs in the middle of the offset printer 10. There is no reason to stop the loading conveyors 21a and 21b because the printing is done in parallel connected offset presses rather than printing directly on the loading conveyors 21a and 21b. What is necessary is to control the loading of the printing object of the carrier lifter 20 so that a printing object may not be supplied to the offset printing press which stopped operation | movement. This is similar to some disconnections in the parallel connection of electrical circuits that do not interrupt the current flow in the entire circuit.
또한, 옵셋 인쇄기(10)에 사용되는 블랭킷은 소모품으로서 자주 교체를 하여야 하며, 정기적, 비정기적으로 옵셋 인쇄기(10)의 검점 및 유지보수가 필요한데, 블랭킷의 교체, 옵셋 인쇄기의 보수 등은 생산 라인의 가동 중에서도 개별적으로 이루어질 수 있으므로 유지 보수에 있어서도 획기적이다.In addition, the blanket used in the offset printing machine 10 must be replaced frequently as a consumable, and the inspection and maintenance of the offset printing machine 10 is necessary regularly and irregularly. The replacement of the blanket and the maintenance of the offset printing machine are performed on the production line. It can be made individually even during the operation, which is a breakthrough in maintenance.
도 8은 본 발명의 일실시예에 따른 병렬 옵셋 인쇄장치로서, 다수의 옵셋 인쇄기(10)가 로딩 컨베이어(21a, 21b)의 측면에 병렬적으로 위치하여 로딩 컨베이어(21a, 21b) 상의 인쇄대상물이 옵셋 인쇄기(10)에 공급되어 인쇄되는 병렬 옵셋 인쇄장치로서, 상기 옵셋 인쇄기(10)를 포함한 일영역의 구성품이 하나의 옵셋 인쇄 세트를 이루어 병렬 옵셋 인쇄장치에 조립되거나 탈착이 가능한 것을 특징으로 한다. 전술한 병렬 옵셋 인쇄장치도 하나의 예일 수 있으며, 도 3에 점선 블럭으로 표시된 옵셋 인쇄 세트(1a, 1b)가 그 예이다. 8 is a parallel offset printing apparatus according to an embodiment of the present invention, in which a plurality of offset printing presses 10 are positioned in parallel with side surfaces of the loading conveyors 21a and 21b to print on the loading conveyors 21a and 21b. A parallel offset printing device which is supplied to and printed on the offset printing machine 10, characterized in that components of one area including the offset printing machine 10 can be assembled or detached to a parallel offset printing device by forming one offset printing set. do. The above-described parallel offset printing apparatus may be one example, for example, the offset printing sets 1a and 1b indicated by dotted blocks in FIG. 3.
이러한 조립식 병렬 옵셋 인쇄장치는 사용자에게 최적의 맞춤형 공정조건을 제공한다. 인쇄대상물의 종류, 전극의 종류, 요구되는 전극의 전기적 특성, 전극의 종횡비 등을 고려하여 적층 인쇄 회수를 고려하게 되며, 산출된 적층 인쇄 회수와 설비 공간, 원하는 택트 타임 등을 감안하여 사용자가 옵셋 인쇄 세트를 몇 개를 가져갈지 정할 수 있으며, 이에 따라 옵셋 인쇄 세트를 조립하여 구성할 수 있다.This prefabricated parallel offset printing device provides the user with optimal customized process conditions. The number of laminated prints is considered in consideration of the type of printed object, the type of electrode, the required electrical characteristics of the electrode, and the aspect ratio of the electrode. You can determine how many print sets you want to take, and you can assemble and configure the offset print sets accordingly.
또한, 설치 후에도 공정조건의 변화 등에 따라 옵셋 인쇄 세트의 가감 조립이 가능하여 외부환경 등의 다변화에 쉽게 적응이 가능하다.In addition, even after installation, it is possible to assemble or subtract the offset printing set according to the change of process conditions, and thus it is easily adaptable to the diversification of the external environment.
특히, 점검 및 유지보수가 요청되는 옵셋 인쇄 세트를 여분의 옵셋 인쇄 세트로 간단히 교체함으로써 공정의 중단 없이 유지 보수가 가능한 점에서 진보적이다.In particular, it is progressive in that maintenance can be performed without interruption of the process by simply replacing the offset print set that is required for inspection and maintenance with an extra offset print set.
본 발명은, 복잡하고 어려운 패턴 얼라인 문제를 원천적으로 해결할 뿐만 아니라 옵셋 공정의 미세선폭 구현이라는 장점을 손상시키지 않으면서, 양산성에서도 장점을 지니고, 유지 보수에 있어서도 획기적인 옵셋 인쇄 장치를 제공할 수 있어 산업적으로 매우 유용하다.The present invention not only solves the complicated and difficult pattern alignment problem at the source, but also has advantages in mass productivity without compromising the advantages of realizing the fine line width of the offset process, and can provide an innovative offset printing apparatus in maintenance. It is very useful industrially.
