타이어 제조용 성형드럼의 구동장치{Drive apparatus of building drum for tire manufacture}Drive apparatus of building drum for tire manufacture

본 발명은 타이어 제조시 타이어에 사용되는 모든 구성 반제품을 순차적으로 붙여서 원통형의 그린타이어를 만드는 성형드럼의 구동장치에 관한 것으로, 더욱 상세하게는 성형드럼의 직경방향으로 수축/팽창과 회전 기능이 단일 구동원에 의해 일체로 이루어지는 타이어 제조용 성형드럼의 구동장치에 관한 것이다.The present invention relates to a driving device of a forming drum to form a cylindrical green tire by sequentially attaching all the semi-finished products used in the tire during the manufacture of a tire, and more specifically, a single shrinkage / expansion and rotation function in the radial direction of the forming drum. It relates to a driving device of a forming drum for tire production, which is integrally formed by a driving source.

타이어를 제조할 때 성형공정에서는 타이어에 사용되는 모든 구성품(예를 들어, 카카스, 트레드, 벨트, 인너라이너, 사이드월 등)을 성형드럼에서 제조 시방서에 의거 순차적으로 붙여서 원통형의 그린타이어를 제조하도록 되어 있다.When manufacturing tires, the molding process produces cylindrical green tires by sequentially attaching all the components used in the tires (e.g., carcass, tread, belt, inner liner, sidewall, etc.) in the molding drum according to the manufacturing specifications. It is supposed to.

여기서 종래 성형드럼의 회전은 모터에 연결된 풀리와 타이밍 벨트 등으로 연결되어 회전력을 전달받아 회전하도록 되어 있으면서 이 성형드럼의 직경방향으로 수축 또는 팽창작업은 압축공기를 이용하여 드럼의 외경이 커지거나 축소되는 구조로 되어 있었다.Here, the rotation of the conventional molding drum is connected to a pulley and a timing belt connected to the motor, and is rotated by receiving a rotational force. It became a structure to become.

즉, 종래 타이어의 성형공정에 설치되는 성형드럼은 수평이동만을 통해 타이어를 구성하는 반제품 재료를 권취하고 타 위치로 재료를 이동해 주기 위해 수축/ 팽창 역할을 수행함에 따라 2개의 동력전달 과정을 가지게 되고, 이에 따라 성형드럼의 회전 동력전달 메커니즘과 수축/팽창 메커니즘이 별도의 장치로 구비되어 설비공간이 커지게 되고 부대설비가 증가되는 문제점을 지니고 있었다.In other words, the forming drum installed in the conventional tire forming process has two power transmission processes by winding the semi-finished material constituting the tire only by horizontal movement and performing a contraction / expansion role to move the material to another position. Accordingly, the rotational power transmission mechanism and the contraction / expansion mechanism of the forming drum were provided as separate devices, which resulted in an increase in facility space and an increase in additional equipment.

이에 본 발명은 상기와 같은 종래 문제점을 해결하기 위해 발명된 것으로, 그린타이어를 성형하는 성형드럼의 회전과 수축/팽창 작동이 하나의 서보모터의 동력으로 이루어짐에 따라 설비의 단축화와 설비공간의 축소가 가능한 타이어 제조용 성형드럼의 구동장치를 제공함에 그 목적이 있다.Accordingly, the present invention has been invented to solve the conventional problems as described above. As the rotation and contraction / expansion operation of the forming drum for molding the green tire is made by the power of one servo motor, the equipment is shortened and the equipment space is reduced. It is an object of the present invention to provide a driving device of a forming drum for manufacturing a tire.

상기와 같은 목적을 달성하기 위한 본 발명은 회전축을 통해 전달된 동력으로 회전하면서 이 회전축을 중심으로 직경방향으로 수축/팽창이 이루어지는 타이어 제조용 성형드럼의 구동장치에 있어서, 상기 성형드럼을 회전시키는 회전축을 서보모터의 감속기에 연결된 구동기어와 맞물린 피동기어를 갖춘 내부 잭 스크류축에 접속 및 이탈되는 브레이크를 구비한 클러치와 볼 베어링을 매개로 연결되면서 성형드럼에 연결되고, 상기 성형드럼은 내부 잭 스크류축의 끝단에 설치된 슬라이더에 작용하는 경사 슬라이딩 선형레일을 구비하여 이루어진 구조로 되어 있다.The present invention for achieving the above object, in the driving device of the forming drum for tire manufacturing is made to shrink / expand in the radial direction about the rotating shaft while rotating with the power transmitted through the rotating shaft, the rotating shaft for rotating the forming drum Is connected to the forming drum by means of a ball bearing and a clutch having a brake connected to and disengaged from the inner jack screw shaft having a driven gear engaged with a drive gear connected to a reduction gear of the servomotor, and the forming drum is connected to the inner jack screw. It has a structure provided with the inclined sliding linear rail which acts on the slider provided in the edge part of an axis | shaft.

상기와 같은 본 발명에 따른 타이어 제조용 성형드럼의 구동장치는 단일 서보모터의 동력원을 이용하여 성형드럼의 수축/팽창과 회전이 이루어짐에 따라 설비공간의 감축과 설비 부대시설을 감소시킬 수 있는 장점을 지닌다.The driving device of the forming drum for tire manufacturing according to the present invention as described above has the advantage that the shrinkage / expansion and rotation of the forming drum by using a power source of a single servomotor can reduce the installation space and reduce the installation facilities.
