Description

타이어 반제품인 코드 사이드 제거용 절단장치{A cutting apparatus for cord side removal of tire material}A cutting apparatus for cord side removal of tire material}

본 발명은 타이어 제조시 압연공정을 거친 토핑(Topping)된 텍스타일 코드(Textile Cord)의 사이드를 재단 공정에서 균일한 폭으로 절단하는 타이어 반제품인 코드 사이드 제거용 절단장치에 관한 것이다.The present invention relates to a cutting device for removing cord side, a tire semi-finished product for cutting a side of a topping textile cord that has undergone a rolling process during tire production to a uniform width in a cutting process.

기히 공지된 바와 같이 타이어 제조시 생코드지 양면에 일정한 고무를 입히는 압연 공정을 마친 타이어 반제품인 텍스타일 코드는 다음 공정인 재단공정으로 이송되어 와인더에 감아 주도록 되어 있는바, 여기서 상기 토핑된 텍스타일 코드가 렛오프(Let-Off) 장치에서 공급되어 와인더에 권취될때, 상기 텍스타일 코드의 사이드부위를 제거한 다음, 일정한 폭을 가진 텍스타일 코드만이 와인더에 권취하도록 되어 있다.As is well known, the textile cord, which is a tire semi-finished product after the rolling process of applying a certain rubber on both sides of the raw cord paper when the tire is manufactured, is transferred to a cutting process, which is the next process, to be wound on a winder, wherein the topping textile cord When supplied from a let-off device and wound on the winder, the side portions of the textile cord are removed, and only the textile cord having a constant width is wound on the winder.

그러나 종래에는 상기 텍스타일 코드의 사이드 부위를 제거할때 별도의 커팅장치를 이용하지 않고 종방향으로 배열되어진 토핑된 코드의 일부 가닥을 물리적인 힘에 의해서 제거하도록 되어 있는데, 이와 같은 종래 텍스타일 코드의 사이드부위 제거 방식은 코드의 일부 가닥을 물리적인 힘에 의해서 제거함에 따라 사이드 부위가 제거된 텍스타일 코드의 토핑 고무가 벗겨져서 코드 가닥이 외부로 노출되어진다.However, conventionally, when removing the side portion of the textile cord is to remove some strands of the topping cord arranged in the longitudinal direction without using a separate cutting device by the physical force, such a side of the conventional textile cord In the part removal method, some strands of the cord are removed by physical force, so that the topping rubber of the textile cord from which the side parts are removed is peeled off and the cord strand is exposed to the outside.

이와 같이 코드 가닥이 노출된 텍스타일 코드는 코드와 코드를 죠인트할 때 발생할 수 있는 오픈현상을 야기하는 문제점이 있었다.As such, the exposed code strands of textile code had a problem of causing an open phenomenon that may occur when joining the code with the code.

이에 본 발명은 상기와 같은 종래 문제점을 해결하기 위해 발명된 것으로, 토핑된 텍스타일 코드의 사이드 부위를 제거할때 코드 가닥이 노출되지 않도록 토핑고무 부위만을 절단하여 코드와 코드를 죠인트 할때 오픈 현상을 방지한 개선된 타이어 반제품인 코드 사이드 제거용 절단장치를 제공함에 그 목적이 있다. Therefore, the present invention was invented to solve the above-mentioned conventional problems. When removing the side portions of the topping textile cords, only the topping rubber portion is cut so that the cord strands are not exposed, thereby opening the phenomenon when joining the cord and the cord. It is an object of the present invention to provide a cutting device for cord side removal, which is an improved tire semifinished product.

상기와 같은 목적을 달성하기 위한 본 발명은 토핑된 텍스타일 코드가 렛 오프부에서 공급되어 일련의 롤들을 거쳐서 와인더에 권취되는 롤 작업장치에 있어서, 상기 렛 오프부와 와인더 사이에 텍스타일 코드의 사이드 부위를 제거하는 절단부가 설치되되, 이 절단부에는 커터 위치용 서보모터에 의해 왕복 이동하는 시소식 커터 지지용 브라켓트가 볼 스크류에 장착되고, 히팅 커터를 갖춘 상기 시소식 커터 지지용 브라켓트는 2개의 센서 사이에 설치되어 이루어진 구조로 되어 있다.In order to achieve the above object, the present invention provides a roll working apparatus in which a toped textile cord is supplied from a let off portion and wound around a winder through a series of rolls, wherein the textile cord is formed between the let off portion and the winder. A cutting part for removing the side portion is installed, and the cutting part is equipped with a seesaw cutter support bracket which is reciprocated by a servomotor for the cutter position, and the seesaw cutter support bracket with a heating cutter includes two The structure is provided between the sensors.

이하, 본 발명을 첨부된 예시 도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 절단장치가 토핑된 텍스타일 코드를 공급하는 렛 오프부와 사이드가 제거된 이 텍스타일 코드를 권취하는 롤 작업부의 와인더 사이에 설치된 구성도이고, 도 2는 본 발명의 요부인 절단 장치의 확대 설명도이다.1 is a block diagram installed between the let off portion for supplying the textile cord topping the cutting device according to the present invention and the winder of the roll work portion winding the textile cord is removed side, Figure 2 is a main part of the present invention It is an explanatory explanatory drawing of a phosphorus cutting device.

본 발명은 토핑된 텍스타일 코드(1)가 렛 오프부(2)에서 공급되어 일련의 롤(3a, 3b, 3c)들을 거쳐서 와인더(4)에 권취되는 재단공정의 롤작업장치에 있어서, 상기 렛 오프부(2)와 와인더(4)사이에 텍스타일 코드(1)의 사이드 부위를 제거하는 절단부(5)가 설치되되, 이 절단부(5)에는 커터 위치용 서보모터(6)에 의해 왕복 이동하는 시소식 커터 지지용 브라켓트(7)가 볼스크류(10)에 장착되고, 히팅 커터(8)를 갖는 상기 시소식 커터 지지용 브라컷트(7)는 2개의 센서(9) 사이에 설치되어 이루어진 구조로 되어 있다.The present invention relates to a roll working apparatus of a cutting process in which a toped textile cord (1) is supplied from a let off portion (2) and wound on a winder (4) via a series of rolls (3a, 3b, 3c). Between the let-off part 2 and the winder 4, a cutting part 5 for removing the side part of the textile cord 1 is provided, which is reciprocated by the servo motor 6 for the cutter position. A moving seesaw cutter support bracket 7 is mounted to the ball screw 10, and the seesaw cutter support bracket 7 having a heating cutter 8 is installed between two sensors 9. It is made of structure.

상기와 같이 이루어진 본 발명은 히팅커터(8)를 이용하여 텍스타일 코드(1)의 사이드 트리밍시 이 텍스타일 코드(1) 원단의 폭 불균일로 인해서 코드가닥(1a)이 손상되는 것을 방지하는 절단장치로서, 토핑된 텍스타일 코드(1)가 도 1의 화살표 방향을 따라 이동할 때, 절단부(5)에서 이 텍스타일코드(1)의 사이드 부위를 절단 제거하여 균일한 폭을 가진 텍스타일 코드(1)는 와인더(4)에 권취되고 이 절단된 사이드 부위(1b)는 별도의 라인을 따라 공지의 사이드 부위 제거용 와인더로 공급되어 권취된다.The present invention made as described above is a cutting device that prevents damage to the cord strand (1a) due to the non-uniform width of the fabric of the textile cord (1) during side trimming of the textile cord (1) using the heating cutter (8) When the topping textile cord 1 moves in the direction of the arrow in FIG. 1, the side of the textile cord 1 is cut off at the cutting part 5, so that the textile cord 1 having a uniform width is winder. The side part 1b wound up and wound by (4) is supplied to a well-known side part removal winder along a separate line, and wound up.

한편, 본 발명의 작용을 설명하면, 상기 토핑된 텍스타일 코드(1)가 도 3에 도시된 바와 같이 코드폭 변화 내지는 권취 센터링 정도의 불량으로 인해 화살표 방향으로 이동하게 되면, 시소식 커터 지지용 브라켓트(7)와 히팅 커터(8)가 화살표 방향으로 각도 변위를 일으키게 된다.On the other hand, when explaining the operation of the present invention, when the toped textile cord (1) is moved in the direction of the arrow due to the change in the code width change or winding centering degree as shown in Figure 3, the seesaw cutter support bracket (7) and the heating cutter (8) cause angular displacement in the direction of the arrow.

이때 이 시소식 커터 지지용 브라켓트(8)의 각도 변위는 2개의 센서(9)가 이를 감지하여 변위를 측정하게 되고, 변위된 신호를 커터 위치용 서보모터(6)로 인가시킨다.At this time, the angular displacement of the seesaw cutter support bracket 8 detects the two sensors 9 to measure the displacement, and applies the displaced signal to the servo position 6 for the cutter position.

그러면 상시 센서(9)들로부터 절단부(5)의 각도변위를 수신한 서보모터(6)가 볼스크류(10)를 작동시키어 도 4와 같이 이 절단부(5)의 히팅 커터(8)와 토핑된 텍스타일 코드(1)의 직각의 균형 상태를 유지시킴에 따라 이 텍스타일 코드(1)의 사이드 부위는 토핑 부위에서 정확하게 절단되면서 코드가닥(1a)이 외부로 노출되지 않고 절단되어진다.Then, the servomotor 6 which receives the angular displacement of the cutting part 5 from the constant sensors 9 operates the ball screw 10, and toppings with the heating cutter 8 of this cutting part 5 as shown in FIG. As the right angle of the textile cord 1 is maintained, the side portion of the textile cord 1 is cut precisely at the topping portion and the cord strand 1a is cut without being exposed to the outside.

상기와 같은 본 발명에 따른 타이어 반제품인 코드 사이드 제거용 절단장치는 타이어 제조시 재단작업중 코드의 폭 변경이나 센터링 불량에 의해서 생기는 코드가닥의 변위가 야기되어도 이를 정확하게 보정하여 토핑된 코드의 사이드 부위를 절단함에 따라 이 코드가닥이 외부로 노출되거나 절단되는 일이 없도록 되어 있다.Cord side removal cutting device is a semi-finished product according to the present invention as described above is corrected even if the displacement of the cord strand caused by the width change of the cord or poor centering during cutting work to correct the side portion of the cord topping As the cord is cut, the cord strand is not exposed to the outside or cut.
