Description
본 발명은 타이어 제조에 사용되는 반제품인 스틸벨트(steel belt)를 일정규격으로 재단하는 절단장치에 관한 것으로, 특히 스틸벨트의 스틸코드 배열방향에 따라 커터의 절단방향의 자동전환이 가능하도록 된 타이어 스틸벨트의 절단장치에 관한 것이다.The present invention relates to a cutting device for cutting a steel belt (steel belt), which is a semi-finished product used in the manufacture of tires, to a certain standard, and in particular, a tire which enables automatic switching of the cutting direction of the cutter according to the steel cord arrangement direction of the steel belt. The present invention relates to a cutting device for a steel belt.
일반적으로, 타이어를 구성하는 여러 가지 반제품중 스틸벨트는 트레드(tread)와 카카스(carcass)사이에 삽입되는 코드(cord)층으로써, 도 4 내지 도 5 에서 보는 바와 같이, 금속재질인 여러가닥의 스틸코드(steel cord; 8) 상/하에 얇은 고무층(7)이 덧씌워져 압착된 것을 말하는데, 이 스틸벨트(9)는 타이어 제조공정에 사용될 때에는 일정길이로 절단하여 사용하게 된다.In general, the steel belt of the various semi-finished products constituting the tire is a cord layer inserted between the tread and the carcass, as shown in Figures 4 to 5, a plurality of strands of metal The steel cord (steel cord 8) of the thin rubber layer (7) is overlaid and pressed to say, this steel belt (9) is used to cut a certain length when used in the tire manufacturing process.
여기서, 상기 스틸벨트(9)를 절단하는 절단장치에 대해 살펴보면, 도 6 내지 도 7 에서 보는 바와 같이, 로드리스실린더(rodless cylinder)로서 좌/우방향으로 신장 및 수축되는 좌우이동실린더(101), 이 좌우이동실린더(101)에 연결되는 프레임(102), 이 프레임(102)에 부착되어 상/하방향으로 신장 및 수축되는 상하이동실린더(103), 이 상하이동실린더(103)의 하부에 부착되는 소정형상의 브래킷(104), 이 브래킷(104)에 고정/장착되는 원형의 커터(105)로 구성되어, 이 커터(105)의 하부, 즉 커터 플레이트(cutter plate)상에 스틸벨트(9)가 놓여지게 되면, 상기 상하이동실린더(103)가 신장되어 상기 커터가 스틸벨트(9)와 맞닿게 되고, 이후 좌우이동실린더(101)에 의해 프레임(102)이 좌측 또는 우측으로 이동되는 동시에, 상기 커터(105)가 스틸벨트(9)를 가로지면서 커터 플레이트와의 마찰에 의해 구름이동하여 상기 스틸벨트(9)를 절단하게 된다.Here, looking at the cutting device for cutting the steel belt (9), as shown in Figure 6 to Figure 7, the rodless cylinder (rodless cylinder) left and right to move in the left and right direction and contraction to the contraction , The frame 102 connected to the left and right moving cylinder 101, the shanghai copper cylinder 103 attached to the frame 102 and extended and contracted in an up / down direction, under the shanghai copper cylinder 103. It is composed of a bracket 104 of a predetermined shape to be attached, and a circular cutter 105 fixed / mounted to the bracket 104, and a steel belt (on a lower portion of the cutter 105, that is, a cutter plate). When 9) is placed, the shankdong cylinder 103 is extended so that the cutter is in contact with the steel belt 9, and then the frame 102 is moved left or right by the left and right moving cylinder 101. At the same time, the cutter 105 traverses the steel belt 9 with the cutter plate. The steel belt 9 is cut by rolling by friction.
그러나, 상기 스틸벨트의 스틸코드는 일정한 각도를 형성하며 배열되어 있기 때문에 상기 커터의 절단방향(도 4 에서 화살표 A로 도시됨)과는 일치하지 않게 된다. 따라서 스틸코드의 배열방향과 일치시켜 스틸벨트를 절단할 수 없기 때문에 커터가 스틸코드를 절단하는 과정에서 스틸벨트의 절단불량 또는 절단장치의 고장원인이 되는 문제점이 있었다.However, since the steel cords of the steel belts are arranged at a predetermined angle, they do not coincide with the cutting direction of the cutter (shown by arrow A in FIG. 4). Therefore, the steel belt can not be cut in accordance with the arrangement direction of the steel cord, there is a problem that the cutter is a failure of cutting the steel belt or failure of the cutting device in the process of cutting the steel cord.
이에 본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로, 스틸벨트의 스틸코드 배열방향에 따라 절단장치의 커터의 절단방향이 자동전환될 수 있도록 되어, 스틸벨트의 절단불량을 방지하고 커터의 손상을 예방할 수 있도록 된 타이어 스틸벨트의 절단장치를 제공하는데 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, the cutting direction of the cutter of the cutting device can be automatically switched according to the steel cord arrangement direction of the steel belt, to prevent the poor cutting of the steel belt and It is an object of the present invention to provide a cutting device for a tire steel belt that can prevent damage.
상기와 같은 목적을 달성하기 위한 본 발명은, 좌우이동실린더의 하부에 상하이동실린더가 부착되고, 이 상하이동실린더에 프레임이 고정되며, 이 프레임내에 볼베어링을 매개로 자유회전이 가능하도록 된 커터가 장착되되, 이 커터의 자유회전은 복귀스프링에 의해 일정한 힘으로 구속받도록 구성되어, 상기 커터의 절단방향을 스틸코드의 배열방향과 일치시켜 스틸벨트를 절단할 수 있게 된다.The present invention for achieving the above object, the shanghai copper cylinder is attached to the lower left and right moving cylinder, the frame is fixed to the shanghai copper cylinder, the cutter is to enable free rotation through the ball bearing in the frame Mounted, the free rotation of the cutter is configured to be constrained by a constant force by the return spring, it is possible to cut the steel belt by matching the cutting direction of the cutter with the arrangement direction of the steel cord.
이하 본 발명을 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 1 은 본 발명에 따른 절단장치의 정면도이고 도 2 는 도 1 의 측면도이며 도 3 은 도 1 은 저면도이고 도 4 는 스틸벨트를 절단하도록 된 커터의 절단방향이 도시된 스틸벨트의 평면도이며 도 5 는 도 4 의 I-I선 단면도로서, 본 발명은 로드리스실린더로서 좌/우측 방향으로 신장 및 수축되는 좌우이동실린더(1), 이 좌우이동실린더(1)의 하부에 연결되어 상/하 방향으로 신장 및 수축되는 상하이동실린더(2), 이 상하이동실린더(2)의 끝단에 부착되는 프레임(3), 이 프레임(3)의 양측에 설치되는 복귀스프링(4), 이 복귀스프링(4)의 내측에 구비되는 볼베어링(5), 이 볼베어링(5)을 매개로 시계방향 또는 반시계방향으로 자유회전이 가능하도록 설치되는 원형의 커터(6)로 구성된다.1 is a front view of a cutting device according to the present invention, FIG. 2 is a side view of FIG. 1, FIG. 3 is a bottom view, and FIG. 4 is a plan view of a steel belt showing a cutting direction of a cutter to cut a steel belt. FIG. 5 is a cross-sectional view taken along line II of FIG. 4. The present invention relates to a left / right moving cylinder 1 extending and contracting in a left / right direction as a rodless cylinder, and connected to a lower portion of the left / right moving cylinder 1 to an up / down direction. Shanghai copper cylinder (2) stretched and contracted by, a frame (3) attached to the end of the shanghai cylinder (2), return springs (4) provided on both sides of the frame (3), the return spring (4) Ball bearing (5) provided inside the), and the circular cutter (6) is installed so as to allow free rotation in the clockwise or counterclockwise direction via the ball bearing (5).
이에 따라, 작업자가 상기 좌우이동실린더(1)와 상하이동실린더(2)를 조작하여 커터 플레이트(도시 않됨)상에 놓여진 스틸벨트(9)위로 커터(6)를 위치시킨 후, 상기 상하이동실린더(2)를 신장시켜 커터(6)를 스틸벨트(9)와 맞물리게 하고, 상기 좌우이동실린더(1)를 조작하여 커터(6)를 이동시키게 되면, 상기 커터(6)가 스틸벨트(9)의 고무층(7)을 가르면서 조금 이동되다가 금속재질의 스틸코드(8)와 맞부딪치게 된다.Accordingly, the operator operates the left and right moving cylinder 1 and the shanghai moving cylinder 2 to position the cutter 6 on the steel belt 9 placed on a cutter plate (not shown), and then the shanghai moving cylinder (2) is elongated so that the cutter 6 is engaged with the steel belt 9, and the left and right moving cylinder 1 is operated to move the cutter 6, so that the cutter 6 is moved to the steel belt 9 While moving a little while breaking the rubber layer (7) of the metal material will be encountered with the steel cord (8).
이때, 상기 커터(6)가 시계방향 또는 반시계방향으로의 운동이 구속되어 있다면(즉, 고정되어 있다면), 이 커터(6)에 의해 스틸코드(8)가 절단될 것이지만, 본 발명에 따른 커터(6)는 시계 또는 반시계방향으로의 회전이 자유롭고, 다만 이 자유회전을 구속하는 힘은 상기 복귀스프링(4)에 의해 이루어지게 된다.At this time, if the cutter 6 is constrained in the clockwise or counterclockwise motion (i.e., fixed), the steel cord 8 will be cut by the cutter 6, but according to the invention The cutter 6 is free to rotate clockwise or counterclockwise, but the force restraining this free rotation is achieved by the return spring 4.
그러나, 이 구속력은 커터(6)와 스틸코드(8)가 맞부딪치는 저항력에 비해 미약한 정도이므로 커터(6)와 스틸코드(8)가 맞부딪치게 되면, 상기 복귀스프링(4)이 압축변형되면서 커터(6)의 절단방향(도 4 에서 화살표 B로 도시됨)이 스틸코드(8)의 배열방향을 따라 변하게 된다.However, since the restraining force is weak compared to the resistance force between the cutter 6 and the steel cord 8, when the cutter 6 and the steel cord 8 collide with each other, the return spring 4 compressively deforms. The cutting direction of the cutter 6 (shown by arrow B in FIG. 4) is changed along the arrangement direction of the steel cord 8.
이에 따라, 상기 커터(6)는 스틸코드(8)의 배열방향을 따라 그 절단방향을 변화시키면서 스틸벨트(9)를 절단하게 되고, 이후 스틸벨트(9)의 절단이 완료되면, 커터(6)의 절단방향을 유지시키고 있던 스틸코드(8)가 없어짐에 따라 상기 복귀스프링(4)의 탄성복원력에 의해 커터(6)가 본래의 위치로 되돌아 오게 된다.Accordingly, the cutter 6 cuts the steel belt 9 while changing the cutting direction along the arrangement direction of the steel cord 8, and when the cutting of the steel belt 9 is completed, the cutter 6 As the steel cord 8, which has maintained the cutting direction of C, disappears, the cutter 6 is returned to its original position by the elastic restoring force of the return spring 4.
이상 설명한 바와 같이 본 발명에 따르면, 스틸벨트내의 스틸코드의 배열방향에 따라 커터의 절단방향이 자동적으로 변경될 수 있게 되어, 스틸벨트의 재단이 원활히 이루어질 수 있으며, 무리한 절단으로 인한 절단장치의 변형 및 손상을 방지할 수 있는 효과가 있다.As described above, according to the present invention, the cutting direction of the cutter can be automatically changed according to the arrangement direction of the steel cord in the steel belt, so that the cutting of the steel belt can be made smoothly, and the deformation of the cutting device due to excessive cutting And the effect of preventing damage.
