상기와 같이 구성되는 종래의 커팅롤러에 의한 광학시트소재의 가공과정을 설명하면 다음과 같다.Referring to the process of processing the optical sheet material by the conventional cutting roller is configured as described above are as follows.
우선 도 2에 도시된 광학시트 커팅장치(28)에 도 3a에 도시된 1차커팅롤러 (1)와 지지롤러(4)를 장착한 후, 장착된 1차커팅롤러(1)와 지지롤러(4)사이에 상면에 광학시트소재(17)가 부착된 베이스필름(16)이 통과되도록 하면, 1차커팅롤러(1)에 설치된 박판커터(3)의 1차형상커팅날부(3a)에 의해 광학시트소재(17)에 1차형상이 커팅되는 동시에 박판커터(3)의 홀커팅날부(3b)에 의해 베이스필름(16)의 양측방에 2차가공을 위한 위치결정용 통공(16a)이 관통형성된다.First, the primary cutting roller 1 and the supporting roller 4 shown in FIG. 3A are mounted on the optical sheet cutting device 28 shown in FIG. 2, and then the mounted primary cutting roller 1 and the supporting roller ( 4) When the base film 16 with the optical sheet material 17 attached to the upper surface passes therebetween, by the primary shape cutting blade portion 3a of the thin plate cutter 3 installed on the primary cutting roller 1. The primary shape is cut on the optical sheet material 17, and the positioning hole 16a for secondary processing is formed on both sides of the base film 16 by the hole cutting blade portion 3b of the thin plate cutter 3. Penetrating.
이와 같이 1차커팅롤러(1)에 의한 1차가공이 완료된 후에는 상기 광학시트 커팅장치(28)에 장착된 1차커팅롤러(1)와 지지롤러(4)를 도 3b에 도시된 2차커팅롤러(10)와 지지롤러(13)로 교체한 다음, 2차커팅롤러(10)와 지지롤러(13)사이에 1차가공공정을 거친 광학시트소재(17)가 부착된 베이스필름(16)을 다시 통과시키게 된다.After the primary processing by the primary cutting roller 1 is completed as described above, the secondary cutting roller 1 and the supporting roller 4 mounted on the optical sheet cutting device 28 are removed. Replaced by the cutting roller 10 and the support roller 13, and then the base film 16 is attached to the optical sheet material 17 after the primary processing process between the secondary cutting roller 10 and the support roller 13 Passed) again.
이 때, 2차커팅롤러(10)와 지지롤러(13)사이에 삽입된 베이스필름(16)의 양측방에 관통형성된 위치결정용 통공(16a)에는 2차커팅롤러(10)의 양측방에 각각 돌출형성된 이송돌기핀(11c)이 순차적으로 걸리게 되어 베이스필름(16)을 이송돌기핀 (11c)의 피치간격만큼 이송시키게 되면서 베이스필름(16)의 상면에 부착된 광학시트소재(17)에는 2차커팅롤러(10)에 설치된 박판커터(12)의 2차형상커팅날부(12a)에 의해 2차형상이 커팅된다.At this time, the positioning hole (16a) formed in both sides of the base film 16 inserted between the secondary cutting roller 10 and the support roller 13 in both sides of the secondary cutting roller 10. The projection protrusion pins 11c protruding from each other are sequentially caught to transfer the base film 16 by the pitch interval of the transfer protrusion pins 11c, and the optical sheet material 17 attached to the upper surface of the base film 16 is provided. The secondary shape is cut by the secondary shape cutting blade portion 12a of the thin plate cutter 12 installed in the secondary cutting roller 10.
그러나, 상기와 같이 구성되는 종래의 커팅롤러는 1차가공시 1차커팅롤러(1)의 홀커팅날부(3b)에 의해 베이스필름(16)의 양측방에 관통형성되는 위치결정용 통공(16a)의 직경이 2차가공시 2차커팅롤러(10)의 원통형 몸체(11)에 형성된 이송돌기핀(11c)이 원할하게 결합될 수 있도록 이송돌기핀(11c)의 직경보다 약간 크게 형성되므로써 2차가공시 2차커팅롤러(10)의 이송돌기핀(11c)이 위치결정용 통공(16a)마다 헐겁게 삽입된다.However, the conventional cutting rollers configured as described above are positioned through holes 16a formed on both sides of the base film 16 by the hole cutting blades 3b of the primary cutting roller 1 during the primary processing. When the secondary diameter is slightly larger than the diameter of the feed projection pin (11c) so that the feed projection pin (11c) formed on the cylindrical body 11 of the secondary cutting roller 10 during the secondary processing can be coupled smoothly The feed projection pin 11c of the secondary cutting roller 10 is loosely inserted in every positioning hole 16a.
이로 인하여 2차가공시 2차커팅롤러(10)의 이송돌기핀(11c)에 의해 베이스필름(16)이 이송될 때마다 이송방향과 좌우방향으로 미세한 공차를 발생시키게 되는데, 이러한 공차들이 계속 누적됨에 따라 2차커팅롤러(10)의 박판커터(12)에 의한 2차가공위치가 점차 어긋나게 되어 연속적인 가공불량이 발생하게 되는 문제점이 있었다.Therefore, when the base film 16 is transported by the feed projection pin 11c of the secondary cutting roller 10 during the secondary processing, fine tolerances are generated in the feeding direction and the left and right directions, and these tolerances are accumulated continuously. Accordingly, there is a problem that the secondary machining position by the thin plate cutter 12 of the secondary cutting roller 10 gradually shifts, causing continuous processing defects.
이와 같은 문제점을 해소하기 위하여 작업현장에서는 작업자가 주기적으로 2차가공이 완료된 광학시트소재(17)를 하나하나 밝은 조명에 비춰가며 확대경으로 확인하는 품질검사를 실시하고 있지만, 주로 투명한 소재로 이루어진 광학시트소재 (17)에 정밀하게 커팅된 1차형상의 커팅선과 2차형상의 커팅선사이의 미세한 간격변화를 이송방향과 좌우방향으로 일일이 확인하여 불량품을 선별해내는데에는 상당한 시간과 노력이 소요되므로 생산성이 현저히 떨어지게 되는 문제점이 있었다.In order to solve such a problem, in the workplace, the worker periodically inspects the optical sheet material 17, which has been secondarily processed, one by one with bright illumination, and checks it with a magnifying glass. It takes considerable time and effort to sort out the defective items by checking the minute gap change between the primary shape cutting line and the secondary shape cutting line precisely cut on the sheet material 17 in the feeding direction and the left and right directions. There was a problem that fell significantly.
상기 문제점을 해결하기 위하여 본 발명은 광학시트 커팅장치에 교대로 장착되어 베이스필름의 상면에 부착된 광학시트소재를 1차와 2차에 걸쳐 순차적으로 형상커팅하게 되는 1차ㆍ2차커팅롤러의 몸체외주연에 설치되는 박판커터의 전단부양측에 베이스필름의 양측방에 가공위치확인용 표시부를 형성시키는 돌기부가 각각 설치되도록 구성되므로써, 광학시트소재의 커팅가공시 1차ㆍ2차커팅롤러에 각각 설치된 돌기부에 의해 베이스필름의 양측방에 주기적으로 형성되는 1차표시부와 2차표시부사이에 발생되는 간격변화를 통해 베이스필름의 이송거리에 대한 누적공차 및 좌우유동으로 인하여 발생되는 가공불량상태를 용이하게 검출할 수 있게 되므로 더욱 더 신속하고 정확한 품질검사가 가능하게 되어 생산성을 대폭 향상시킬 수 있도록 하는 것을 기술적 과제로 한다.In order to solve the above problems, the present invention is a primary and secondary cutting roller of the primary and secondary cutting rollers are alternately mounted on the optical sheet cutting device to sequentially cut the first and second optical sheet materials attached to the upper surface of the base film.
