본 발명은 타이어 압출공정의 압출기에서 압출하는 스트립 압출물을 성형드럼에 직접 와인딩 시킬 때 성형드럼이나 압출기에서 이상 발생시 압출 스트립 공급이 연속적으로 이루어져 자동화 생산과 제품의 품질 균일화를 도모할 수 있는 윈치 저장존을 갖는 타이어 압출 스트립 저장장치에 관한 것이다.According to the present invention, when the strip extrudate extruded from the extruder of the tire extrusion process is directly wound onto the forming drum, the extrusion strip is continuously supplied when an abnormality occurs in the forming drum or the extruder, so that winch storage can be achieved for automated production and quality uniformity of the product. A tire extrusion strip storage device having a zone.

최근 타이어 제조에 있어서 압출기에서 뽑아져 나온 압출물인 고무코아(Rubber core)를 카렌다를 통해 압출 스트립으로 형상화 한 다음, 이를 성형드럼에 직접 와인딩을 시키어 타이어 반제품인 사이드 월(Side wall), 림쿠션(Rim cushion) 및, 트레드(Tread) 등을 제조하고 있는바, 이러한 타이어 반제품 제조방식은 압출기와 일체형인 카렌다를 곧 바로 성형드럼에 접촉시키어 압출 스트립을 이 성형드럼에 와인딩 시키도록 되어 있으나, 카렌다가 점유하는 공간이 커서 설비의 레이아웃(Lay-out)이 불리하였다.In the recent tire manufacturing, rubber core, an extrudate extracted from an extruder, is shaped into an extrusion strip through a calender, and then directly wound on a molding drum, such as side walls, rim cushions, etc. Rim cushions and treads are manufactured, and this tire semi-finished product manufacturing method is such that a calendar integrated with an extruder is immediately brought into contact with the molding drum to wind the extrusion strip onto the molding drum. The occupied space was so large that the layout of the equipment was disadvantageous.

또한 상기와 같은 종래 압출 스트립 방식은 카렌다와 성형드럼이 직접 접촉하는 시스템으로서, 압출기의 압출물 토출속도와 성형드럼의 회전속도가 동일한 속도를 유지해야 하며, 압출기 또는 성형드럼의 이상 발생시 작업 정지로 연계되는 단점이 있었다.In addition, the conventional extrusion strip system as described above is a system in which the calendar and the forming drum are in direct contact with each other, and the extrusion speed of the extruder and the rotating speed of the forming drum must be maintained at the same speed. There was a disadvantage.

이와 더불어 성형드럼의 규격 교체용 정지시간을 가질 경우 압출기로 동시에 작업을 중지해야 하는데, 실제적으로 압출기가 완전히 정지 했다가 재운전할 경우에는 여러 가지 품질력에 악영향을 끼치는 문제점도 지니고 있었다.In addition, if you have a stop time for replacing the specifications of the molding drum, the extruder must stop working at the same time, but when the extruder completely stopped and restarted, there was a problem that adversely affects various quality forces.

이외에도 종래에는 상대적으로 무거운 카렌다를 성형드럼에 직접 접촉시킴으로서 전체적인 작업 동작의 신속성과 정밀성이 떨어지는 폐단 등도 있었다.In addition, in the related art, a relatively heavy calendar was directly contacted with a forming drum, and thus, there was a closed end, etc., in which the overall work operation was less rapid and less accurate.

이에 본 발명은 상기와 같은 종래 문제점을 해결하기 위해 발명된 것으로, 압출기와 성형드럼 사이에 압출 스트립의 저장존(Storage zone)을 설치하여 압출기 혹은 성형드럼 이상시에도 연속적인 자동화 생산이 가능하면서 제품의 품질 균일화도 도모할 수 있는 윈치 저장존을 갖는 타이어 압출 스트립 저장장치를 제공함에 그 목적이 있다.Accordingly, the present invention was invented to solve the above-mentioned problems, and by installing a storage zone of the extrusion strip between the extruder and the forming drum, continuous automated production is possible even when the extruder or the forming drum is abnormal. It is an object of the present invention to provide a tire extrusion strip storage device having a winch storage zone capable of achieving quality uniformity.
