Description

타이어 보강벨트의 공급 제어장치{Supply control apparatus of tire reinforcement belt}Supply control apparatus of tire reinforcement belt

본 발명은 타이어 성형공정에서 벨트 성형드럼에 권취되는 보강벨트를 오버랩(Overlap) 없이 균일하게 권취될 수 있도록 공급하는 타이어 보강벨트의 공급 제어장치에 관한 것이다.The present invention relates to a supply control apparatus for a tire reinforcing belt for supplying a reinforcing belt wound on a belt forming drum in a tire forming process so as to be uniformly wound without an overlap.

타이어 제조시 성형공정에서는 타이어에 사용되는 모든 구성재료 성형드럼에서 순차적으로 붙여서 원통형의 그린타이어(Greentire)를 만드는 작업인바, 이러한 타이어의 성형공정에서 도 2에 도시된 바와 같이 벨트 성형드럼(7)에 보강벨트(2)와 트레드(미도시)를 차례로 권취하여 그린타이어의 2차 케이스를 만들게 되는데, 상기 벨트 성형드럼(7)에 기 권취된 스틸벨트(10) 위에 일정한 폭을 갖는 보강벨트(2)를 추가로 와인딩하여 타이어 트레드의 강성을 향상시키는 과정을 거치게 된다.In the manufacturing process of tires, the operation is to make cylindrical green tires by sequentially attaching all the component materials forming drums used for the tires. In the process of forming the tires, as shown in FIG. Winding the reinforcing belt (2) and the tread (not shown) in order to make a secondary case of the green tire, the reinforcing belt having a constant width on the steel belt (10) pre-wound in the belt forming drum (7) The additional winding of 2) improves the tire tread stiffness.

여기서 상기 보강벨트(2)를 벨트 성형드럼(7)의 스틸벨트(10) 위에 권취시킬 때 이 보강벨트(2) 폭(W)의 허용오차가 ±1㎜이고 보강벨트(2) 간의 간격(d)도 0 ~ 1㎜로 오버랩되지 않게 감겨지도록 작업하게 되어 있다.In this case, when the reinforcing belt 2 is wound on the steel belt 10 of the belt forming drum 7, the tolerance of the width W of the reinforcing belt 2 is ± 1 mm and the spacing between the reinforcing belts 2 d) is designed to be wound so as not to overlap with 0-1mm.

상기 보강벨트(2) 간의 간격인 피치(Pitch)는 벨트 성형드럼(7) 상에서 작업자가 설정해야 하는데, 일반적으로 1피치는 보강벨트(2)의 폭(W) + 0 ~ 0.5㎜로 적용하는 것이 보통이다.The pitch, which is the interval between the reinforcing belts 2, should be set by the operator on the belt forming drum 7. In general, 1 pitch is applied to the width W of the reinforcing belt 2 + 0 to 0.5 mm. Is common.

여기서 1피치는 보강벨트(2)가 벨트 성형드럼(7)에서 1와인딩시 횡 방향의 이동량을 말한다.Here, one pitch refers to the amount of movement in the transverse direction when the reinforcing belt 2 is one-wound in the belt forming drum 7.

예를 들어 상기 보강벨트(2)의 폭(W)이 10㎜이면 1피치는 10㎜ ~ 10.5㎜로 설정해서 보강벨트(2) 간의 간격이 도 2와 같이 오버랩되지 않도록 되어 있다.For example, if the width W of the reinforcing belt 2 is 10 mm, one pitch is set to 10 mm to 10.5 mm so that the space between the reinforcing belts 2 does not overlap as shown in FIG.

그러나 종래 상기 벨트 성형드럼(7)에 보강벨트(2) 권취 중 이 보강벨트(2)의 폭(W)이 허용오차인 ±1㎜를 초과하게 되면, 미리 설정한 일정한 피치 간격으로는 이 보강벨트(2) 간의 간격을 0 ~ 1㎜로 맞출 수 없게 되는데, 이때에는 상기 보강벨트(2) 간의 오버랩이 발생하게 되고, 이러한 보강벨트(2) 간의 오버랩은 품질 균일성에 악영향을 주게 되며, 수율에서 불리한 문제점이 제기되어 왔다.However, if the width W of the reinforcing belt 2 during the winding of the reinforcing belt 2 to the belt forming drum 7 exceeds the tolerance ± 1 mm, the reinforcement is performed at a predetermined pitch interval. The gap between the belts 2 cannot be adjusted to 0 to 1 mm, in which case an overlap between the reinforcing belts 2 occurs, and the overlap between the reinforcing belts 2 adversely affects the quality uniformity, and yields Disadvantages have been raised.

이에 본 발명은 상기와 같은 종래 문제점을 해결하기 위해 발명된 것으로, 벨트 성형드럼에서 보강벨트 권취시 이 보강벨트 간의 간격을 오버랩 없이 일정하게 권취하도록 유지시킴으로써 품질 균일성의 향상과 외관 부적합 발생을 미연에 방지할 수 있는 타이어 보강벨트의 공급 제어장치를 제공함에 그 목적이 있다.Therefore, the present invention has been invented to solve the above-mentioned problems, and when the reinforcing belt is wound in the belt forming drum, the gap between the reinforcing belts is kept to be constantly wound without overlap, thereby improving the quality uniformity and appearance defects.
