타이어의 보강재 부착장치Tire reinforcement attachment device

본 발명은 타이어의 보강재 부착장치에 관한 것으로, 특히 타이어의 연속적인 흐름을 차단함이 없이 부착시켜줌은 물론 사이드월부의 강성도 효과적으로 높일 수 있도록 된 타이어의 보강재 부착장치에 관한 것이다.The present invention relates to a reinforcing material attachment device of the tire, and more particularly to a reinforcement material attachment device of the tire that can be effectively attached to the stiffness of the side wall as well as attached without blocking the continuous flow of the tire.

일반적으로, 타이어는 생고무나 화학고무에 여러 가지 성분을 혼합하여 제조한 고무응 이용하여 카카스와 비드 및 보강재와 트레드등과 같은 부분을 서로 접합한 후, 몰딩장치를 이용하여 소정 압력과 온도로 가열 및 가압하여 1본의 완성된 타이어를 제조하게 된다.In general, tires are made by mixing rubber and raw rubber with various components, and then joining parts such as carcass and beads, reinforcements and treads, and heating them to a predetermined pressure and temperature using a molding device. And pressurized to produce one finished tire.

이와 같은 타이어의 구성부분중 보강재는 타이어의 사이드부위의 강성을 높이기 위해 반드시 필요한 부분으로서 통상, Steel과 Nylon 및 2겹의 Carcass 등의 재질로 이루어져 사이드월과 카카스 사이로 내장되어 지게 된다.The reinforcement of such a tire component is an essential part for increasing the rigidity of the side portion of the tire, and is usually made of steel, nylon, and two-ply carcass, and embedded between the sidewall and the carcass.

그러나, 상기와 같이 타이어에 가해지는 하중을 지지하는 보강재가 구비된 타이어를 제조하려면, 타이어를 완성하기 전에 별도의 성형기계에서 보강부재를 부착시켜 주어야만 하는 공정이 추가되고, 이와 같은 공정의 추가는 타이어의 제조에 필요한 연속공정을 끊어주게 되므로 부착작업에 많은시간이 소요되는 문제가 있었다.However, in order to manufacture a tire provided with a reinforcement for supporting a load applied to the tire as described above, a process of attaching a reinforcing member in a separate molding machine before the tire is completed is added. Since the continuous process required for the production of tires is cut off, there is a problem that a lot of time is required for the attachment work.

이에 본 발명은 상기와 같은 문제를 해소하기 위해 발명된 것으로, 타이어의 연속작업의 흐름을 차단하지 않고 사이드월부에 보강재를 부착하여 부착시간을 줄임은 물론 사이드월부의 강성도 더욱 향상시킬 수 있도록 된 타이어의 보강재 부착장치를 제공함에 그 목적이 있다.Accordingly, the present invention was invented to solve the above problems, the tire is attached to the side wall without reinforcing the flow of the continuous operation of the tire to reduce the attachment time as well as to further improve the rigidity of the side wall Its purpose is to provide a reinforcement attachment device of the.
