본 발명은 공기입 타이어의 제조장치에 있어서 각 반제품을 성형기의 카카스 드럼 위에 자동으로 부착하는 장치와 이들 반제품의 처음과 끝이 겹치는 부위를 압착하는 스플라이싱장치가 압착롤과 함께 구비된 타이어 성형기에 관한 것이다.The present invention provides a pneumatic tire manufacturing apparatus for automatically attaching each semi-finished product onto a carcass drum of a molding machine and a splicing device for compressing a portion where the first and the end of these semi-finished products overlap with a compression roll. It relates to a molding machine.

승용차용 공기입 타이어의 제조공정인 성형공정에서 카카스드럼에 인너라이너(Inner Liner)와 바디플라이(Body Ply)를 공급하여 권취하게 되는데, 권취작업의 시작은 수작업 혹은 자동으로 공급되는 반제품의 첫 부위를 카카스 드럼위에 압착력을 가해 권취가 되도록 구성되어 있다.In the process of forming pneumatic tires for passenger cars, the inner casing drum and the body ply are supplied to the carcass drum for winding up. The starting of the winding operation is the first of semi-finished products supplied manually or automatically. The site | part is comprised so that it may wind up by applying a pressing force on a carcass drum.

반제품의 권취 작업이 종료된 후 반제품의 첫 끝이 겹치는 부위를 별도로 설치된 압착장치를 사용하여 스플라이싱 작업을 하거나 카카스 드럼에 공급되는 반제품의 첫 부위를 압착하는 압착 장치를 사용하여 스플라이싱 작업을 실시하고 있어 작업 시간이 길어지는 단점이 잇다. 또한 작업시간의 단축을 위해 스플라이싱 작업을 삭제할 경우 완제품 타이어의 불량품 발생률이 증가되는 문제점이 있다.After the winding of the semifinished product is finished, splicing the overlapping part of the first end of the semifinished product by using a separately installed pressing device or by using a pressing device that compresses the first part of the semifinished product supplied to the carcass drum. There is a disadvantage that the working time is long because the work is performed. In addition, when the splicing work is deleted in order to shorten the working time, there is a problem in that the incidence of defective products of the finished tire is increased.

즉 상기 종래 기술의 경우 카카스 드럼에서 압착작업을 하기 위하여 다음 공정으로 넘어가지 못하고 성형기 상단 혹은 하단에 설치되어 있는 압착기를 작동시켜야 한다. 이때 다음 공정으로 넘어가기 위해 한 쌍의 비드(Bead)가 카카스 드럼과 동심원 축으로 진입을 대기하고 있어 압착작업에 소요되는 시간만큼 생산시간이 지연되고 있어 전체적인 타이어 제조 시간이 길어지는 단점이 있다. 즉 한 쌍의 비드를 장착하는 설비와 스플라이싱 설비가 서로 다른 동작 수순으로 작동하기 때문에 작업 시간이 과다 소요된다.That is, in the case of the prior art, the pressing machine installed at the upper or lower end of the molding machine should be operated without going to the next process in order to compress the carcass drum. At this time, a pair of beads waiting to enter the carcass drum and the concentric shaft to move to the next process, the production time is delayed by the time required for the crimping operation, the overall tire manufacturing time is long. . In other words, since the equipment for mounting a pair of beads and the splicing equipment operate in different operating procedures, excessive work time is required.

종래 기술의 경우 도 1에 도시된 바와 같이 카카스 드럼(1) 위로 공급되는 반제품(2)의 첫 부위를 카카스 드럼(1)의 표면에 부착하도록 하는 과정이 수작업 또는 환봉 형태의 압착롤(3, Roll)을 사용하여 반제품(2)을 카카스 드럼(1)에 부착되어 권취가 가능하도록 압착력을 가하고 있다. 상기 권취작업 종료 후 반제품의 첫 끝 부위의 겹치는 부위(b)가 서로 분리되지 않도록 별도의 스플라이싱 장치를 사용하여 압착작업을 해주거나 혹은 처음 카카스 드럼에 반제품이 부착되도록 사용하였던 환봉형태의 압착롤을 사용하여 반제품의 첫 끝 부위가 겹치는 곳을 압착하는 작업을 하고 있다.In the prior art, the process of attaching the first part of the semi-finished product 2 supplied over the carcass drum 1 to the surface of the carcass drum 1 as shown in FIG. 3, Roll) is used to attach the semi-finished product 2 to the carcass drum 1 to apply a compressive force to enable the winding. After completion of the winding operation, the overlapping portion (b) of the first end portion of the semi-finished product was pressed using a separate splicing device so as not to be separated from each other, or the round bar type used to attach the semi-finished product to the first carcass drum The press roll is used to press the overlapping areas of the first end of the semi-finished product.

이때 별도의 압착(스플라이싱)장치를 작동하는데 작업시간이 증가되거나 카카스 드럼이 작업 압착 작업 위치만큼 회전하게 되어 작업 시간이 증가한다.At this time, the operation time is increased to operate a separate crimping (splicing) device or the carcass drum is rotated by the work crimping work position, thereby increasing the work time.

본 발명은 상기와 같은 타이어를 제조하는 과정 중 성형공정에서 카카스 드럼에 권취되는 반제품의 첫 부위와 끝 부위를 압착함에 있어 카카스 드럼에 반제품이 처음 권취될 때 압착력을 가했던 환봉 형태의 압착롤이나 반제품 공급장치에 설치된 별도의 압착장치의 사용을 삭제하여 전체적인 작업시간과 완제품 타이어의 불량률 감소를 도모하고자 상기 압착롤에 인접하여 스플라이싱장치를 연설하도록 함에 그 특징이 있다.
The present invention in the process of manufacturing the tire as described above in the first step and the end portion of the semi-finished product wound on the carcass drum in the molding process in the case of pressing the first half of the semi-finished product on the carcass drum was pressed in the form of a round bar In order to reduce the overall working time and the defective rate of the finished tire by eliminating the use of a separate pressing device installed on a roll or a semi-finished product feeding device, the splicing device is characterized to be adjacent to the pressing roll.

도 2는 본 발명에 따른 스플라이싱장치가 압착롤과 함께 구비된 타이어 성형기의 부분도이다.2 is a partial view of a tire molding machine in which the splicing device according to the present invention is provided with a pressing roll.
