타이어 제조용 성형기의 반제품 압착장치{Half-finished products splice stitcher of building machine}Half-finished products splice stitcher of building machine

본 발명은 타이어 제조시 소경 성형기 드럼에서 타이어 구성품의 반제품인 인너라이너 및 사이드월의 반제품과, 카카스를 와인딩 시킨 상태에서 이들의 연결부위를 동시에 조인트 압착하는 타이어 제조용 성형기의 반제품 압착장치에 관한 것으로, 더욱 상세하게는 성형기 드럼에 와인딩된 인너라이너 및 사이드월로 이루어진 반제품과 2장 카카스들로 이루어진 반제품들을 동시에 조인트 압착하여 작업사이클 시간을 대폭 절감하는 타이어 제조용 성형기의 반제품 압착장치에 관한 것이다.The present invention relates to a semi-product crimping device of a tire manufacturing machine for joint-compressing joints of the inner liner and sidewall of semi-finished components of a tire component in a small-diameter molding machine drum at the time of manufacturing a tire, and at the same time the carcass is wound. More particularly, the present invention relates to a semi-product pressing device for a tire manufacturing machine for significantly reducing work cycle time by jointly crimping a semi-finished product composed of an inner liner and a sidewall wound on a molding machine drum and a semi-finished product composed of two carcasses.

타이어 제조시 재단공정을 마친 각종 반제품들, 예를 들어 인너라이너, 사이드월, 카카스 등은 성형공정으로 이동되어 그린타이어를 제조하기 위해 성형기 드럼에 순차적으로 와인딩되어 진다.Various semi-finished products, such as inner liner, sidewall, carcass, etc., which have been cut during tire manufacturing, are moved to a molding process and sequentially wound on a molding machine drum to manufacture green tires.

이러한 타이어 성형공정에서 드럼에 각종 반제품을 와인딩 시킬 때 종래에는 도 3 (A)에 도시된 바와 같이 먼저 인너라이너와 사이드월로 이루어진 반제품(102)을 회전축(105)에 의해 회전하는 카카스 드럼(101)에 와인딩한 후 이들의 연결부위 를 확인한 후, 도 3 (B)에 도시된 바와 같이 압착장치(103)가 공지의 실린더에 의해 하강되어 이 반제품의 연결부위에서 접촉하고, 이어 도 3 (C)에 도시된 바와 같이 모터(106)에 의해 구동하는 압착장치(103)가 가이드 축(107)을 따라 이동하여 조인트 연결하였다.When winding various semi-finished products to the drum in such a tire forming process, conventionally, as shown in FIG. 3 (A), a carcass drum that first rotates the semi-finished product 102 formed of an inner liner and a sidewall by a rotating shaft 105 ( After winding to 101) and confirming their connections, the pressing device 103 is lowered by a known cylinder, as shown in FIG. 3 (B), and then contacted at the connection of the semifinished product, followed by FIG. 3 (C). As shown in FIG. 2, the pressing device 103 driven by the motor 106 is moved along the guide shaft 107 to jointly connect.

이렇게 인너라이너와 사이드월로 이루어진 반제품의 압착작용이 완료된 다음, 카카스의 반제품들을 다시 앞선 와인딩 압착 결합된 반제품 위에 다시 와인딩하여 앞서 설명한 동일한 방식으로 2장의 카카스의 압착작업을 반복 수행함에 따라 자연히 작업시간이 증가되어 생산량 향상을 위해 이를 개선시킬 필요가 있었다.After the crimping action of the semi-finished product consisting of the inner liner and the sidewall is completed, the carcass semi-finished products are re-wound again on the preceding press-combined semi-finished product, and the two carcass pressing processes are repeated in the same manner as described above. The increased working time needed to be improved to improve production.

이에, 본 발명은 상기와 같은 종래 문제점을 감안하여 제안된 것으로, 소경 성형기의 드럼에서 각종 반제품들을 와인딩하여 이들을 결합부위를 조인트 압착시킬 때 한번 작업사이클에 의해 동시에 압착작용이 이루어짐에 따라 작업사이클 시간의 단축으로 생산량이 향상되는 타이어 제조용 성형기의 반제품 압착장치를 제공함에 그 목적이 있다.Accordingly, the present invention has been proposed in view of the conventional problems as described above, the work cycle time according to the simultaneous crimping action by one working cycle when the joints are pressed by winding various semi-finished products in the drum of the small diameter molding machine It is an object of the present invention to provide a semi-finished crimping device of a molding machine for producing a tire that the production amount is improved by shortening.

상기와 같은 목적을 달성하기 위한 본 발명은 소경 성형기 드럼에 인너라이너와 사이드월로 이루어진 반제품과 2장의 카카스 반제품을 와인딩 시키고, 이들의 연결부위를 압착 스티처로 이용하여 조인트 압착시키는 타이어 제조용 성형기의 반제품 압착장치에 있어서, 상기 성형기 드럼에 감겨진 인너라이너와 사이드월로 이루어진 반제품과 제 1 카카스 반제품 및 제 2 카카스 반제품의 접합부분에 각각 맞추어 세팅되는 여러 개의 압착 스티처들이 원형의 비드세터 내부 둘레에 각각 설치되고, 이 비드세트가 드럼 축을 따라 왕복 이동하여 드럼에 와인딩된 반제품들의 접합부위를 동시에 조인트 압착시키는 구조로 되어 있다.The present invention for achieving the above object is a tire molding machine for winding a semi-finished product consisting of an inner liner and a side wall and two pieces of carcass semi-finished product to the small-diameter molding machine drum, and using a joint portion thereof as a compression stitcher. In the semi-finished crimping device, a circular bead setter is formed of a plurality of crimp stitchers which are set to the joints of an inner liner and a sidewall wound on the molding machine drum, and a joint of the first and second carcass semi-finished products. Each bead is provided around the inside, and the bead set reciprocates along the drum axis to joint-compress the joint portions of the semi-finished products wound on the drum.

상기와 같이 본 발명은 소경 성형기 드럼에 타이어 반제품들을 와인딩 시키어 이들의 접합부위를 조인트 압착시킬 때, 단일 작업공정으로 동시에 조인트 압착이 이루어짐에 따라 작업 사이클 시간의 단축으로 생산성 향상이 이루어진다.As described above, according to the present invention, when the semi-finished products are wound on a small-diameter molding machine drum, the joint compression of these joints is performed at the same time, so that the joint compression is performed at the same time in a single working process, thereby improving productivity by reducing the work cycle time.
