Description

타이어 성형기의 반제품 스프라이싱장치{A preassembly splicing apparatus of tire building}A preassembly splicing apparatus of tire building

본 발명은 타이어의 성형공정시 반제품 플라이들을 순차적으로 붙여서 원통형의 그린타이어를 만드는 성형기에 관한 것으로, 더욱 상세하게는 타이어의 1차성형 작업시 성형드럼에 감긴 반제품의 겹침(Overlap)부위를 포개어 접합하기 위한 타이어 성형기의 반제품 스프라이싱장치에 관한 것이다.The present invention relates to a molding machine for forming a cylindrical green tire by attaching semi-finished plies in sequence during the molding process of a tire, and more specifically, overlapping and overlapping the overlapped parts of the semi-finished products wound on the forming drum during the primary molding operation of the tire. A semi-finished splicing device for a tire molding machine for

주지된 바와 같이 타이어 제조시 성형공정은 타이어에 사용되는 모든 구성재료인 반제품을 성형기에서 순차적으로 붙여서 원통형의 그린타이어를 만드는 작업으로 타이어의 품질을 거의 좌우하는 중요한 공정이라 할 수 있다.As is well known, the molding process in manufacturing a tire is an important process that almost determines the quality of the tire by attaching all the semi-finished materials used in the tire sequentially in a molding machine to make a cylindrical green tire.

이러한 성형공정중 성형 1차작업에서 성형드럼에 감겨진 반제품의 겹침부위를 서로 포개어 접합하기 위해 스프라이싱장치가 이용되는바, 종래 이와 같은 스프라이싱장치는 도 3에 도시된 바와 같이 성형드럼 쪽으로 전후진되는 몸체(108)에 장력스프링(109)으로 탄설된 스프라이싱 롤(104)들이 폭이 얇고 긴 나이론 재질의 밴드부(103)와 접하여 설치되어 있었다.During the molding process, a splicing apparatus is used to overlap and overlap the overlapping portions of semi-finished products wound on the molding drum in the first molding process. Conventionally, such a splicing apparatus is moved back and forth toward the molding drum as shown in FIG. 3. Splicing rolls 104 rolled on the body 108 to be tensioned with tension springs 109 were installed in contact with the band 103 of a thin nylon material.

상기와 같은 종래 스프라이싱장치는 1차 성형시 프리어셈블리(preassembly)가 성형드럼에 와인딩 되고, 이 스프라이싱 장치의 몸체(108)가 도 3의 화살표 방향으로 하강하여 성형드럼에 감겨진 이 프리어셈블리의 반제품 플라이의 포개진 양단을 탄발성의 스프라이싱 롤(104)과 밴드부(103)를 이용하여 접합시킨 다음, 제1 바디플라이를 와인딩하기 위해 몸체(108)가 다시 상승하도록 되어 있다.In the conventional splicing apparatus as described above, the preassembly is wound on the forming drum during the primary molding, and the body 108 of the splicing apparatus is lowered in the direction of the arrow in FIG. 3 and wound around the forming drum. The folded ends of the semi-finished ply are bonded using elastic splicing rolls 104 and bands 103 and then the body 108 is raised again to wind the first body ply.

이어 상기 제1 바디플라이가 성형드럼에 와인딩 되면, 다시 이 스프라이싱장치의 몸체(108)가 하강하여 앞서 설명한 바와 같이 제1 바디플라이의 포개진 양단을 접합시킨다.Subsequently, when the first body ply is wound on the forming drum, the body 108 of the splicing apparatus is lowered again to bond the overlapped ends of the first body ply as described above.

그런 다음, 제2 바디플라이와 비드를 안착시키기 위해 상술한 방식대로 스프라이싱장치의 몸체(108) 전체는 반복적인 승하강 동작을 계속 수행하게 되는바, 이같이 반제품들을 성형드럼에 와인딩하기 위해 스프라이싱장치의 몸체는 동일한 승하강 작동을 여러 번 반복하게 됨으로 작동시간이 길게 소요되고 끊임없이 진동을 하게 되어 설비의 정도를 떨어뜨리고 노화를 촉진시킴에 따라 결국 설비의 수명이 단축되는 문제점이 있었다.Then, the entire body 108 of the splicing apparatus continues to perform the repeated lifting and lowering operation in the manner described above to seat the second body fly and the beads, thus splicing to wind the semi-finished products to the forming drum. The body of the device has the problem of shortening the life of the facility as it takes a long time and constantly vibrates to reduce the degree of equipment and promote aging by repeating the same lifting operation several times.

이에 본 발명은 상기와 같은 종래 문제점을 해결하기 위해 발명된 것으로, 성형드럼에 감겨진 반제품의 포개진 양단의 접합을 신속하게 수행하여 작업시간의 단축과 스프라이싱 장치의 몸체 승하강 작동을 제거하여 설비 정도의 유지성을 부여하여 설비의 수명을 향상시키는 타이어 성형기의 반제품 스프라이싱장치를 제공함에 그 목적이 있다.Therefore, the present invention was invented to solve the conventional problems as described above, by quickly bonding the two ends of the semi-finished product wound on the molding drum to shorten the working time and eliminating the body lifting operation of the splicing device It is an object of the present invention to provide a semi-finished splicing device for a tire molding machine that provides a maintenance degree of equipment to improve the service life of the equipment.

상기와 같은 목적을 달성하기 위한 본 발명은 성형드럼에 와인딩 되어진 반제품의 포개진 양단을 접합하기 위해 밴드부의 스프라이싱 롤을 이용한 타이어 성형기의 스프라이싱 장치에 있어서, 상기 밴드부의 안쪽면에 접히는 스프라이싱 롤 들은 실린더에 연결된 힌지축을 가진 회동링크와 각각 연결되고, 상기 밴드부의 한쪽 측단은 몸체와 접하는 위치완충용 스프링을 매개로 설치되어 있다.In order to achieve the above object, the present invention provides a splicing apparatus for a tire forming machine using a splicing roll of a band part for joining both ends of a semi-finished product wound on a forming drum, the splicing folded on the inner surface of the band part. The rolls are respectively connected to a rotational link having a hinge shaft connected to the cylinder, and one side end of the band portion is provided through a position buffer spring in contact with the body.

이하 본 발명을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명이 적용된 타이어 성형기의 부분 도면이고, 도 2는 본 발명의 요부를 나타낸 확대 구성도이다.1 is a partial view of a tire molding machine to which the present invention is applied, and FIG. 2 is an enlarged configuration diagram showing the main part of the present invention.

본 발명은 도면에 도시된 바와 같이 성형기(10)의 성형드럼(1)의 상부쪽에설치되어 이 성형드럼(1)에 와인딩 되어진 반제품의 포개진 양단을 접합시키는 장치로서, 상기 성형드럼(1)에 와인딩 되어진 반제품(2)의 포개진 양단부위를 접합하기 위해 밴드부(3)와 스프라이싱 롤(4)을 이용한 타이어 성형기의 스프라이싱 장치에 있어서, 상기 밴드부(3)의 안쪽면에 접하는 스프라이싱 롤(4)들은 실린더(5)에 연결된 힌지축(6)을 가진 회동링크(7)와 각각 연결되고, 이 밴드부(3)의 한쪽 측단은 몸체(8)에 보유지지된 위치 완충용 스프링(9)을 매개로 설치되어 있다.The present invention is an apparatus for joining the two ends of the semi-finished product is installed on the upper side of the forming drum (1) of the molding machine 10 as shown in the figure, the winding of the forming drum (1), the forming drum (1) In the splicing apparatus of a tire forming machine using the band part 3 and the splicing roll 4 for joining the overlapped both ends of the semi-finished product 2 wound on the splice, the splicing in contact with the inner surface of the band part 3. The rolls 4 are respectively connected to a rotational link 7 having a hinge shaft 6 connected to the cylinder 5, and one side end of the band portion 3 is a position buffer spring held in the body 8. 9) is installed as a medium.

여기서 상기 위치 완충용 스프링(9)은 실린더(5)의 수축/팽창 작동에 의해 스프라이싱 롤(4)들이 도 2와 같이 화살표 방향으로 승하강 회동되어 작동할 때 밴드부(3)의 늘어남에 대한 보상용 스프링 역할을 수행한다.Wherein the position buffer spring (9) is for the stretching of the band portion (3) when the splicing rolls (4) is moved up and down in the direction of the arrow as shown in Figure 2 by the contraction / expansion operation of the cylinder (5) Serves as a compensating spring.

이어 본 발명의 작동을 설명한다.Next, the operation of the present invention will be described.

공지의 방식으로 반제품(2)이 공급되어 성형드럼(1)에 와인딩 되어져서 이 반제품(2)의 포개진 양단부위를 접합할 때, 상기 몸체(8)의 실린더(5)가 팽창 작동하게 되면, 스프라이싱 롤(4)들은 회동링크(7)와 힌지축(6)을 이용하여 하부쪽으로 각회동하게 되어 밴드부(3)를 점선위치(도 2참조)로 이동시키게 됨으로서 이 스프라이싱 롤(4)들과 밴드부(3)가 반제품(2)의 포개진 양단을 접합하게 된다.When the semifinished product 2 is supplied in a known manner and wound to the forming drum 1 to join the overlapped ends of the semifinished product 2, the cylinder 5 of the body 8 is expanded. The splicing rolls 4 are pivoted downward by using the pivoting link 7 and the hinge shaft 6 to move the band portion 3 to the dotted line position (see FIG. 2). ) And the band portion (3) are joined to both ends of the nested product (2).

이어 다음 제1 벨트를 성형드럼(1)에 공급하기 위해 실린더(5)가 수축하게 되면, 이 스프라이싱 롤(4)들은 원위치 되어지고, 이 제1 벨트가 성형드럼(1)에 감겨지면, 앞서 설명한 바와 같이 실린더(5)의 팽창작동으로 스프라이싱 롤(4)들과 밴드부(3)가 팽창하여 접합하게 된다.Then, when the cylinder 5 is retracted to supply the first belt to the forming drum 1, the splicing rolls 4 are returned to their original positions, and when the first belt is wound on the forming drum 1, As described above, the splicing rolls 4 and the band 3 are expanded and joined by the expansion operation of the cylinder 5.

이렇게 단지 스프라이싱 몸체(8)는 원위치 상태에서 스프라이싱 롤(4)들과밴드부(3)의 팽창/수축 작동만으로 반제품을 접합시키도록 되어 있다.Thus, the splicing body 8 is adapted to join the semifinished product only by the expansion / contraction operation of the splicing rolls 4 and the band portion 3 in the original position.

상기와 같이 본 발명은 성형 1차 작업시 성형드럼에 반제품들의 접합을 신속하게 수행하여 작업시간이 단축되고, 또한 단순한 스프라이싱 롤과 밴드의 작용만으로 원활한 반제품의 접합작업이 이루어짐에 따라 설비의 정도 유지성과 수명 향상이 개선되는 잇점을 갖도록 되어 있다.As described above, the present invention shortens the working time by quickly performing the joining of semi-finished products to the forming drum during the first molding operation, and also the degree of equipment according to the smooth joining work of the semi-finished products by the action of a simple splicing roll and a band. It is intended to have the advantage of improved maintainability and lifespan.
