본 발명은 타이어 제조시 재단공정에서 완성된 반제품 시트를 성형기로 공급시킬 때 이 반제품 시트에 걸리는 장력을 조절하고 공급되는 재료의 유동을 감소시켜 주는 타이어 반제품 시트재료의 장력 조절장치에 관한 것이다.The present invention relates to a tension control device for a semi-finished product sheet material that adjusts the tension applied to the semi-finished product sheet and reduces the flow of the supplied material when the semi-finished sheet finished in the cutting process is manufactured during tire production.

타이어 제조시 재단공정을 마친 반제품들은 카카스(Carcass), 브레카(Breaker), 체파(Chafer), 후립파(Flipper), 인너라이너(Inner liner), 인슈레이션(Insulation) 등 다양한 반제품들로 제조되고 이들 반제품들을 성형기로 보내어 성형기 드럼에서 모든 반제품들을 순차적으로 붙여서 원통형의 그린타이어를 제조하게 된다.Semi-finished products that have been cut during tire manufacturing are manufactured with various semi-finished products such as Carcass, Breaker, Chafer, Flipper, Inner liner, Insulation, etc. These semi-finished products are sent to a molding machine to sequentially attach all semi-finished products from the molding machine drum to produce a cylindrical green tire.

한편, 타이어 반제품 시트재료를 성형기로 공급하기 위해 종래에는 도 3에 도시된 바와 같이 반제품 시트재료를 권취하기 시작하면, 루프부(3)의 반제품 시트재료(2) 저장량이 변화하게 되고, 이것을 감지하여 렛 오프(1, Let-off)에서 권취된 반제품 시트재료(2)를 풀어주게 되면서 권취 동작이 이루어지는데, 이때 상기 루프부(3)에서 권취할 때까지는 롤러(3a)들에 의해 무구동으로 반제품 시트재료(2)가 화살표 방향으로 가이드 되어 도면에 도시하지 않은 성형기의 드럼 쪽으로 공급되어 진다.On the other hand, in order to supply the tire semi-finished sheet material to the molding machine, when the semi-finished sheet material starts to be wound as shown in FIG. 3, the amount of storage of the semi-finished sheet material 2 of the roof part 3 is changed, and this is detected. The winding operation is performed while releasing the semi-finished sheet material 2 wound at the let-off, and is driven by the rollers 3a until it is wound up at the loop portion 3. The semi-finished sheet material 2 is then guided in the direction of the arrow and fed to the drum of the molding machine, not shown.

그러나 종래 반제품 시트재료의 공급장치에서는 렛 오프(1)에서 공급되는 재료의 상태에 따라 루프부(3)에서 반응시간이 일정하지 않아서 권취시 장력변화를 일으키게 되고, 재료 권취시까지 반제품 시트재료(2)의 안내시 회전수단들이 많아서 자연히 재료에 장력이 가해질 뿐만 아니라, 급가속/급정지에 따른 재료의 유동이 심한 문제점 등이 제기되어 왔다.However, in the conventional apparatus for supplying semi-finished sheet material, the reaction time is not constant in the loop part 3 according to the state of the material supplied from the let-off 1, causing a tension change during winding, and the semi-finished sheet material until the material winding ( There are many rotating means in the guidance of 2), and naturally the tension is applied to the material, and the problem of severe flow of the material due to rapid acceleration / sudden stop has been raised.

이에 본 발명은 상기와 같은 종래 문제점을 해결하기 위해 발명된 것으로, 타이어의 반제품 시트재료 권취시 권취속도의 변화에 따른 대응을 신속하게 유지시키어 재료의 장력 발생을 저감시키면서 재료의 가/감속 또는 정지시 유동성을 감소시킨 타이어 반제품 시트재료의 장력 조절장치를 제공함에 그 목적이 있다.Accordingly, the present invention has been invented to solve the conventional problems as described above, while rapidly responding to changes in the winding speed during winding of the semi-finished sheet material of the tire to reduce the tension generation of the material while reducing or reducing the tension of the material It is an object of the present invention to provide a tension control device for a tire semi-finished sheet material having reduced fluidity.

상기와 같은 목적을 달성하기 위한 본 발명은 렛 오프에 권취된 반제품 시트재료를 루프부와 롤러 등을 이용하여 권취장치를 거쳐 성형기의 드럼으로 공급시키는 타이어 반제품 시트재료의 공급장치에 있어서, 상기 권취장치에는 장력 조절부가 설치되되, 이 장력 조절부는 고정롤러와 센서의 신호에 의해 선형 가이드를 따라 전, 후진 이동하는 선형블럭의 가변롤러로 이루어진 구조로 되어 있다.In the present invention for achieving the above object, in the supply device for a semi-finished product sheet material for supplying the semi-finished sheet material wound on the let-off to the drum of the molding machine through a winding device using a loop portion and a roller, etc. The device is provided with a tension control unit, the tension control unit has a structure consisting of a variable roller of the linear block moving forward and backward along the linear guide by the signal of the fixed roller and the sensor.

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

도 1은 본 발명이 적용된 타이어 반제품 시트재료 공급 시스템의 구성을 나타낸 구성도이고, 도 2는 도 1의 요부인 장력 조절부의 확대 구성 평면도이다.1 is a configuration diagram showing a configuration of a tire semi-finished sheet material supply system to which the present invention is applied, and FIG. 2 is an enlarged configuration plan view of a tension control unit, which is a main part of FIG. 1.

본 발명의 설명에 앞서서 종래 장치와 동일한 부분에서는 동일한 참조부호를 부여하여 설명한다.Prior to the description of the present invention, the same parts as in the conventional apparatus will be described with the same reference numerals.

본 발명은 렛 오프(1)에 권취된 반제품 시트재료(2)를 루프부(3)와 롤러(4) 등을 이용하여 권취장치(5)를 거쳐 성형기의 드럼으로 공급시키는 타이어 반제품 시트재료의 공급장치에 있어서, 상기 권취장치(5)에는 장력 조절부(6)가 설치되되, 이 장력 조절부(6)는 고정롤러(7)와 센서(8)의 신호에 의해 선형 가이드(9)를 따라 전, 후진 이동하는 선형블럭(10)의 가변롤러(11)로 이루어져 있다.The present invention provides a semi-finished product sheet material for supplying the semi-finished sheet material 2 wound on the let-off 1 through the winding device 5 to the drum of the molding machine by using the loop part 3 and the roller 4 or the like. In the feeding device, the winding device 5 is provided with a tension control unit 6, the tension control unit 6 is a linear guide (9) by the signal of the fixed roller 7 and the sensor (8) Accordingly, the variable roller 11 of the linear block 10 moving forward and backward is made up.

즉 본 발명은 도 1과 같이 반제품 시트재료(2)가 권취전에 일직선이 되는 부분인 권취장치(5) 부분에다 공급되는 반제품 시트재료(2)가 가변롤러(11)와 고정롤러(7)에 의해 루프될 수 있는 장력 조절부(6)가 설치되어 있는데, 이 장력 조절부(6)의 가변롤러(11)와 고정롤러(7)의 간격조정으로 권취되는 반제품 시트재료(2)의 안내 루프량을 조절할 수 있도록 되어 있다.That is, in the present invention, as shown in FIG. 1, the semifinished sheet material 2 supplied to the winding device 5, which is a portion in which the semifinished sheet material 2 is in a straight line before winding, is applied to the variable roller 11 and the fixed roller 7. There is a tension adjusting section 6 which can be looped by the guide loop of the semi-finished sheet material 2 wound by adjusting the gap between the variable roller 11 and the fixed roller 7 of the tension adjusting section 6. The amount can be adjusted.

이를 좀더 부언하면, 상기 반제품 시트재료가 도면에서 화살표 방향으로 권취되기 시작하면, 상기 장력 조절부(6)의 초음파 센서(8)가 가변롤러(11)의 선형블럭(10)까지 거리를 감지하게 되어 기준치를 벗어나게 되면 상기 렛 오프(1)의 루프부(3)에 저장되어 있는 반제품 시트재료를 추가 모터의 회전수를 조절하여 가속하거나 감속으로 일정 루프량을 가져오게 하거나 덜 가져오게 함으로서 상기 권취장치(5)의 직선부분에서 반제품 시트재료(2)의 루프량을 일정하게 유지시키도록 되어 있다.In other words, when the semi-finished sheet material starts to be wound in the direction of the arrow in the drawing, the ultrasonic sensor 8 of the tension adjusting part 6 detects the distance to the linear block 10 of the variable roller 11. When the reference value is out of the reference value, the semi-finished sheet material stored in the loop portion 3 of the let-off 1 is controlled by adjusting the rotational speed of the additional motor so as to accelerate or decelerate a certain amount of loop or to bring less. The loop amount of the semi-finished sheet material 2 is kept constant at the straight portion of the apparatus 5.

상기와 같은 본 발명에 따른 타이어 반제품 시트재료의 장력 조절장치는 렛 오프 루프부에서 발생하는 반제품 시트재료 장력을 저감시키면서 권취속도 변화에 따라 장력조절을 수행할 수 있고, 권취시 반제품 시트재료의 가/감속 또는 정지시 재료의 유동량을 감소시키는 잇점을 갖는다.The tension adjusting device of the semi-finished sheet material of the tire semi-finished sheet according to the present invention can adjust the tension according to the change of the winding speed while reducing the tension of the semi-finished sheet material generated in the let off loop portion, Has the advantage of reducing the amount of flow of material upon deceleration or stop.
