Description

타이어 반제품 제조용 비드포머장치{Bead former unit for tire manufacture}Bead former unit for tire manufacture

본 발명은 타이어 반제품 중 하나인 비드(Bead)를 배열시키는 비드포머장치(Bead former unit)에 관한 것으로, 특히 비드 배열시 균일한 나선형 형태로 진원도 및 간격 품도 향상과 배열 안정화가 이루어지는 타이어 제조용 비드포머장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bead former unit for arranging beads, one of semi-finished tires. It relates to a former device.

타이어 반제품 중 비드는 타이어의 주입공기 압력 및 외측에 의해 발생하는 타이어 형상의 망가짐을 방지하고, 타이어 주행 중 고장이나 림에서 이탈되지 않도록 안정화시키는 역할을 하도록 되어 있다.Among the semi-finished tire products, the bead serves to prevent the tire shape from being broken due to the inlet air pressure and the outside of the tire, and to stabilize the tire so that it does not come off from a failure or rim while the tire is running.

이러한 비드의 제조 공정시 비드싱글 와이어(Bead single wire)에 고무를 토핑시킨 나비드가 온라인(On-line) 방법으로 공급되어 비드포머장치와 드럼 둘레에 나선형태로 여러 개의 비드가 와인딩되어 배열되는바, 즉 도 5에 도시된 바와 같이 비드포머 본체(1)에서 회전하는 포머축(3)에 설치되는 포머틀(4)의 둘레에 여러 개의 비드(100)들이 와인딩되어 배열될 때 이 비드의 베이스면에 따라 비드(100)의 진원도가 영향을 받게 된다.In the manufacturing process of the beads, a bead with a rubber topping on a single single wire is supplied in an on-line manner, and a plurality of beads are spirally wound around the bead former device and the drum. That is, the base of the bead when a plurality of beads 100 are wound and arranged around the former frame (4) installed in the former shaft (3) rotating in the bead former body (1) as shown in FIG. Depending on the surface, the roundness of the bead 100 is affected.

예를 들어 비드의 베이스면이 고르지 않을 경우 균일한 나선형태의 비드를 와인딩할 수 없을 뿐만 아니라, 와인딩 되는 비드 간의 간격이 일정하지 않아 벌어지게 되어 형성된 비드의 진원도와 간격 품도가 떨어지는 문제점이 제기되었다.For example, if the base surface of the bead is uneven, it is not possible to wind the bead of uniform spiral shape, and the gap between the winding beads is not constant, which is caused by the gap of roundness and gap quality of the formed bead. It became.

또한, 종래에는 상기 포머틀(4)에서 비드 와인딩 및 분리시 배열 형성된 비드의 분리에도 번거로움이 있어서 원활한 작업상태를 유지시키기 위해 이를 개선시킬 필요가 있었다.In addition, in the prior art, the separation of the beads formed at the time of bead winding and separation in the former mold 4 is cumbersome, and thus it is necessary to improve this to maintain a smooth working state.

이에 본 발명은 상기와 같은 종래 문제점을 감안하여 발명된 것으로, 비드싱글 와이어에 고무가 토핑된 일렬 비드를 제조할 때 배열되는 비드의 진원도 확보와 균일한 간격이 유지되어 비드의 배열 안정화를 도모하면서 비드 배열 형성 후 분리가 보다 용이하게 이루어져 생산성 향상에 도움을 주는 타이어 제조용 비드포머장치를 제공함에 그 목적이 있다.Therefore, the present invention has been invented in view of the conventional problems as described above, while securing the roundness of beads arranged at the time of manufacturing single-line beads with rubber topping on the single wire and maintaining a uniform interval, thereby stabilizing the arrangement of the beads. It is an object of the present invention to provide a bead former device for manufacturing a tire, which facilitates separation after forming a bead array, thereby improving productivity.
