본 발명은 레이저를 이용한 합성섬유의 변사절단 방법 및 장치에 관한 것으로 특히 폴리에스터(Polyester)계 섬유를 직조하고 난 뒤 이를 수평이동시키면서 양측에 돌출된 채로 남아있는 위사의 말단부를 레이저로 절단 제어시키는 방법 및 그에 적합한 장치를 제공함에 주안점을 둔 것이다.The present invention relates to a method and apparatus for cutting and cutting a synthetic fiber using a laser. In particular, after weaving a polyester-based fiber, the end portion of the weft yarn which remains protruded on both sides while horizontally moving is controlled by laser cutting. The focus is on providing a method and a suitable device therefor.

일반적으로 섬유는 길이방향으로 신장된 경사 사이에 위사가 직교결합된 형태로 직조되는 바, 직조된 섬유의 양측단에는 절단된 위사의 발단부가 돌출된 상태로 남게되며 이를 변사(selvage)라고 통칭한다.In general, the fibers are woven in the form of orthogonal weft yarns between the longitudinally extending inclination, the ends of the woven fibers are left in the protruding state of the cut weft yarn is called a slavage. .

그런데, 직조되어 제품으로 출고된 섬유에 상기와 같은 변사가 잔류하게 되면 제품의 품질 및 단가를 떨어뜨리게 되는 한 원인이 되고 있으므로 제조공정에서 이를 제거시키고 있다.By the way, when the above-mentioned metamorphic residual in the woven fiber shipped as a product is a cause of the quality and cost of the product is removed, it is removed in the manufacturing process.

따라서, 초기에는 기계적인 방법으로 칼이나 수조작 가위를 이용하여 변사를 절단해왔으나, 이는 절단 작업상의 불편과 번거로움으로 매우 비능률적일 뿐만 아니라, 절단작업의 정밀도가 희박하여 자칫하면 섬유부분까지도 절단하게 되는 문제점이 있었다. 이와 같은 점을 감안하여 그후에 제공된 것이 열을 가하여 절단부위를 지쳐주는 방법이 제공되었으나 이 경우는 항시 화재의 위험성이 상존하고 있어서 안전에 관한 부대 설비를 갖추어야 하며, 처리속도가 매우 늦어서 생산성 저하의 한 요인이 됨은 물론이고 이 역시 변사절단의 정밀도가 낮아 제품의 품질에 악영향을 끼치게 되는 등의 문제점이 있었다.Therefore, in the early days, the knife was cut by a mechanical method using a knife or a hand-operated scissors, but this is not only very inefficient due to the inconvenience and hassle of cutting work, but also the cutting of the fiber is difficult due to the lack of precision. There was a problem. In view of this, there has been provided a method of exhausting the cutting part by applying heat afterwards, but in this case, there is always a risk of fire. Therefore, safety equipment must be provided. As well as being a factor, this also had a problem such as low accuracy of the cut, which adversely affects the quality of the product.

따라서 본 발명의 목적은 상기와 같은 종래의 문제점을 해결함과 동시, 첨단공학분야인 레이저 발진기를 이용하여 그로부터 발생된 레이저로 매우 정밀하게 변사를 절단 제거시키는 방법과 그에 따른 장치를 제공함에 있다.Accordingly, an object of the present invention is to solve the conventional problems as described above, and to provide a method and apparatus for cutting and removing the metamorphosis very precisely with the laser generated therefrom by using a laser oscillator, which is an advanced engineering field.

상기와 같은 목적을 달성하기 위하여 직조된 직물을 펼친 상태로 이송시키는 롤링머신의 일측에 절단 프레임을 설치해 놓고, 레이저 발진기에서 나온 레이저를 유도한 뒤 포커스 마운드 노즐을 이용하여 레이저를 변사부위로 집광주사시키는 헤드를 미세이동 장치와의 연동으로 상기 절단 프레임의 양측에 결합설치하므로서 직조된 직물이 롤링머신에 의해 이동하여 상기 절단 프레임 하방을 지나가게 될 때 양측 헤드에서 주사되는 레이저에 의해 변사가 절단되도록 한 것인바 이를 첨부된 예시도면에 의거 상세히 설명하면 다음과 같다.In order to achieve the above object, the cutting frame is installed on one side of the rolling machine which transfers the woven fabric to the unfolded state, guides the laser from the laser oscillator, and then condenses the laser to the metamorphic region using a focus mount nozzle. By interlocking and installing the head to be coupled to both sides of the cutting frame in conjunction with the micro-moving device so that the yarn is cut by the laser scanning from both heads when the woven fabric is moved by a rolling machine to pass under the cutting frame It will be described in detail based on the accompanying drawings, which are as follows.

도면 제1,2도에서와 같이 일측에 택스타(13)와 피드롤러(14) 및 롤러 가이드(15) 그리고 배칭디바이스(Batching device)(17)등으로 구성된 통상의 직물 이송장치에 있어서 상기 장치일측의 롤러 프레임(16)상에 절단 프레임(1)을 설치한 뒤 상기 절단 프레임(1)의 상부에 설치된 가이드 레일(2)의 양측에는 각기 구동모터(3)(4)와 연결된 볼 스크류(5)(6) 회전 방향에 따라 이송동작하는 슬라이더(7)(8)를 결합설치하였다.As shown in FIGS. 1 and 2, in the conventional fabric conveying apparatus composed of a tack star 13, a feed roller 14, a roller guide 15, a batching device 17, and the like on one side, the apparatus of the present invention. After the cutting frame 1 is installed on the roller frame 16 on one side, ball screws connected to the driving motors 3 and 4 are respectively formed on both sides of the guide rails 2 installed on the cutting frame 1. 5) (6) The sliders 7 and 8, which are transported in accordance with the rotational direction, are mounted.

그리고, 블록(9a)(10a)내부에는 레이저 발진기(12)에서 보내진 레이저를 노즐측으로 반사시키는 반사경과 하부에는 포커스 마운팅 노즐(9b)(10)을 구비한 레이저 주사용 헤드(9)(10)를 구비한 뒤 이를 상기 양측 슬라이더(7)(8)의 브라켓트(7a)(8a)에 각각 고정 설치하였다.A laser scanning head 9 and 10 having a reflecting mirror for reflecting the laser beam sent from the laser oscillator 12 to the nozzle side and a focus mounting nozzle 9b and 10 below the block 9a and 10a. And then fixed to the bracket (7a) (8a) of the two sliders (7) (8), respectively.

이에 따라 상기 헤드(9)(10)는 각기 모터(3)(4)와 연결된 구동 볼 스크류(5)(6)와 나사결합된 슬라이더(7)(8)의 이동에 의해 좌우로 위치이동하여 상호간의 폭을 가변시킬 수 있게 되었으며 헤드 하방의 노즐은 그 후방에 결합시킨 높이 가변수단(19)에 의거 설치높이를 알맞게 가변조정시킬 수 있게 되었다.Accordingly, the heads 9 and 10 are moved left and right by the movement of the sliders 7 and 8 screwed with the driving ball screws 5 and 6 connected to the motors 3 and 4, respectively. The width between each other can be varied, and the nozzle below the head can adjust the installation height appropriately based on the height varying means 19 coupled to the rear thereof.

이상과 같이 구성된 본 발명의 상태를 보면 다음과 같다.Looking at the state of the present invention configured as described above are as follows.

직조된 직물을 이동시키기 전에 양측모터(3) (4)로 슬라이더(7) (8)을 위치이동시켜 헤드(9) (10)하단의 노즐부위가 하방으로 이송될 직물의 양측 변사 절단부의 수직 연장선과 정확하게 일치되도록 맞춰준다.Before moving the woven fabric, move the sliders (7) (8) with the two motors (3) (4) so that the nozzles at the bottom of the heads (9) (10) are perpendicular to the two side yarn cuts of the fabric to be conveyed downwards. Make sure it is exactly the extension line.

그후, 상기 직물이송 장치를 작동시키면서 레이저 발진기(12)를 작동시키게 되면 텍스타(13)와 피드롤러(14), 롤로가이드(15)를 거친 직물(11)이 아이들롤러에 의해 수평으로 이동하여 절단 프레임(1)의 하방으로 통과하게 된다.Subsequently, when the laser oscillator 12 is operated while operating the fabric conveying apparatus, the fabric 11 having passed through the texter 13, the feed roller 14, and the roll guide 15 is moved horizontally by the idle roller. It passes under the cutting frame 1.

이와 동시 양측 헤드(9)(10)의 노즐로부터 직물 양측의 변사절단 부위로 레이저가 집광주사되어 변사(11a)를 절단제거하므로 직물(11)은 변사(11a)가 완전제거된 상태로 계속이동하여 배칭디바이스(17)측으로 낙하하게 되는 것이다.At the same time, the laser is condensed from the nozzles on both sides of the heads 9 and 10 to the edges of the cuts on both sides of the fabric to cut and remove the yarns 11a, so that the fabric 11 continues to move with the yarns 11a completely removed. To fall to the batching device 17 side.

이때, 헤드에서 주사되는 레이저에 의해 변사가 절단될 때 절단부위는 레이저에서 가해진 고온의 에너지에 의해 합성섬유의 경우 순간적인 열적 봉함에 의한 매듭부가 형성되므로 절단부위가 부풀리지 않고 또한 풀리지 않도록 된 우수한 품질의 직물을 얻을 수 있게 된다. 그리고, 절단 가공코져하는 직물의 폭이 좁아지거나 넓혀졌을 경우는 상기에서와 같이 모터(3) (4)를 구동시켜 슬라이더(7) (8)를 위치이동시켜주면 어떠한 경우라도 절단가공이 가능케된다.At this time, when the metabolism is cut by the laser scanning from the head, the cutting part is formed by knots due to instantaneous thermal sealing in the case of synthetic fibers by the high-temperature energy applied from the laser. Quality fabrics can be obtained. When the width of the fabric to be cut is narrowed or widened, the cutting process is possible in any case by driving the motors 3 and 4 to move the sliders 7 and 8 as described above. .

또한, 이와 같이 레이저로 절단가공을 행하므로 종래 수작업 절단시에 발생하던 절단부위의 부풀림이나 먼지가 날리지 않아 양호한 작업환경을 유지할 수 있으며 변사절단 속도 또한 직물이송 장치에 의해 직물이 이동하는 속도에 비례하게 되므로 단위시간당 절단 처리 능력의 월등한 증가로 제품의 생산성을 향상시킬 수 있으며, 화재의 위험성을 완벽하게 배제시킬 수 있는 등의 특출한 효과가 있다.In addition, since the cutting process is performed with a laser as described above, it is possible to maintain a good working environment by not swelling or dusting of the cutting part generated during manual cutting, and the cutting speed is also proportional to the speed at which the fabric is moved by the fabric transfer device. Therefore, it is possible to improve the productivity of the product by an excellent increase in cutting processing capacity per unit time, and has an outstanding effect such as to completely eliminate the risk of fire.
