Description

타이어 제조시 반제품 권출대차와 권취 성형드럼의 스트립 속도 동기장치{A strip velocity synchronizing apparatus of bobbin winding applicator and building drum}A strip velocity synchronizing apparatus of bobbin winding applicator and building drum}

본 발명은 타이어 제조시 사이드월, 체파, 벨트보강재와 같은 반제품의 스트립을 권출대차로부터 이송시키어 성형드럼에 붙이는 스트립 부착장치에 관한 것으로, 더욱 상세하게는 반제품 스트립을 공급하는 권출대차와 이 스트립이 부착되는 권취 성형드럼 사이에서 정확한 스트립 속도의 동기화가 이루어지면서 설비구조의 단순화로 레이 아웃의 감축과 동작 정지의 트레블을 제거하여 생산성 향상이 이루어지는 타이어 제조시 반제품 권출대차와 권취 성형드럼의 스트립 속도 동기장치에 관한 것이다.The present invention relates to a strip attachment device for transferring a strip of semi-finished products, such as sidewalls, sieving, belt reinforcement, from the unloading cart and attaching it to the forming drum, in more detail. Synchronization of the strip speed between the wound molding drums, and the synchronization of the strip speed of the semi-finished unloading bogie and the winding molding drum when manufacturing tires, which improves productivity by eliminating the layout reduction and the stoppage of travel due to the simplification of the equipment structure. Relates to a device.

일반적으로 타이어의 반제품인 각종 스트립들을 압출기에서 뽑아낸 다음, 이들 스트립들은 각각에 맞는 대차에 권취시킨후, 다음 공정인 성형공정으로 이동되어 성형드럼에 이들 스트립을 부착시키도록 되어 있다.In general, after removing various strips, which are semi-finished products of a tire, from the extruder, these strips are wound on a trolley for each one, and then moved to a molding process, which is the next step, to attach these strips to the forming drum.

종래 이러한 대차와 렛오프 스테이션은 각각의 고유작업만 수행하는바, 즉 대차는 반제품 운반, 렛오프 스테이션는 대차에서 반제품 스트립을 풀어주는 역할만 수행함에 따라 자연히 반제품이 성형드럼에 와인딩 되기까지 중간에 서비서(servicer)라는 복잡한 매개체를 이용하는 실정이었다.Conventionally, the trolley and the let-off station perform only their own operations, that is, the trolley carries semi-finished products, and the let-off station only serves to release the semi-finished strips from the trolley. It used to be a complex medium called a servicer.

즉, 종래 상기와 같은 대차와 렛오프 스테이션 구조는 도 2에 도시된 바와 같이 공지의 바퀴와 스풀 등을 갖춘 대차 프레임(101a)에 대차(101)가 설치되고 공지의 모터와 클러치(102) 및 브레이크(103)로 이루어진 렛오프 스테이션(105, Let-off station)이 설치되어 있다.That is, in the conventional bogie and let-off station structure, as shown in FIG. 2, the bogie 101 is installed on the bogie frame 101a having the well-known wheels and spools, and the like. The let-off station 105 which consists of brakes 103 is provided.

여기서 반제품 재료를 장착한 대차(101)는 성형작업지역으로 옮겨지고 상기 렛오프 스테이션(105)에서 클러치(102)에 연결되다.Here the trolley 101 equipped with the semifinished material is transferred to the forming work zone and connected to the clutch 102 at the let-off station 105.

그리고 상기 클러치(102)는 이 렛오프 스테이션(105)의 공지 모터와 체인을매개로 연결되어 있기 때문에 동력 전달이 이루어진다.Since the clutch 102 is connected to the known motor and the chain of the let-off station 105 at a medium, power transmission is performed.

여기서 상기 동력전달축은 대차(101)의 라이너 구동롤러(109)과 함께 회동하면서 재료측 대차(101)에 있는 반제품인 스트립을 풀게 되어 있다.Here, the power transmission shaft rotates together with the liner drive roller 109 of the trolley 101 to release a semi-finished strip in the material side trolley 101.

또한 스풀이 설치된 대차(101)는 브레이크(103)와 연결되어 있기 때문에 반제품과 함께 라이너가 풀어지면서 일정한 장력을 유지하게 되어 있다.In addition, since the trolley 101 provided with the spool is connected to the brake 103, the liner is released together with the semi-finished product to maintain a constant tension.

이와 같은 종래 렛-오프 스테이션은 단순히 반제품 스트립(106)을 대차(101)에서 풀어놓기만 할뿐 그 외의 반제품 스트립(106)의 세팅, 성형드럼(107)으로의 운반 및 이 성형드럼(107)과의 상호 동기속도에 의한 반제품 스트립(106)의 와인딩 등은 모두 성형 서비서(113)상에서 이루어지도록 되어 있다.Such a conventional let-off station merely releases the semifinished strip 106 from the trolley 101, setting other semifinished strips 106, transporting it to the forming drum 107 and the forming drum 107. The winding of the semi-finished strip 106 and the like by mutual synchronous speed with each other are made on the molding service 113.

더욱이 상기 기존 종래 대차(101)는 면직류의 라이너를 이용해 반제품 스트립(106)을 성형드럼(107)에 권취시키므로 이 대차(101)에서 반제품 스트립(106)의 분리측 면에서는 유리하나, 반제품의 정밀 세팅 등에 문제가 있으며 상기 라이너(108)자체에도 정밀도가 떨어지는 문제점이 있었다.Furthermore, the conventional conventional trolley 101 winds the semi-finished strip 106 on the forming drum 107 by using a liner of cotton direct current, which is advantageous in terms of the separation side of the semi-finished strip 106 in this trolley 101. There is a problem in the precision setting and the like, the liner 108 itself has a problem that the accuracy is low.

또한 구동축이 라이너의 스풀축과 연결되므로 이 구동축의 회동속도가 일정한데 비하여 라이너 측의 속도는 스풀의 직경이 커짐에 따라 (라이너가 감겨짐에 따라 직경이 커짐)비례적으로 커지게 되어 있다.In addition, since the drive shaft is connected to the spool shaft of the liner, the rotational speed of the drive shaft is constant, whereas the speed of the liner side is increased proportionally as the diameter of the spool increases (the diameter increases as the liner is wound).

따라서 대차에서 반제품의 풀어지는 속도 조절이 어려우며, 서비서(113)에 부착된 공지의 센서에 의해 일정량만큼 풀어내고 멈추고, 다시 풀어내야 하는 작업의 번거로움이 있었다.Therefore, it is difficult to adjust the release rate of the semi-finished product in the bogie, and by the known sensor attached to the servicer 113, a certain amount of release and stop, there was a hassle of work to release again.

즉 이러한 종래 작업방식은 작업효율을 떨어뜨리고 생산성의 감소와 작업중작업 트러블 등이 야기되는 문제점이 있었다.That is, such a conventional work method has a problem of reducing work efficiency, reducing productivity, and trouble during work.

이에 본 발명은 상기와 같은 종래 문제점을 해결하기 위해 발명된 것으로, 고무 스트립과 같은 반제품과 라이너지가 대차에서 권출되어 성형드럼에 권취될때 보다 정확한 속도로 이송되어 와인딩됨에 따라 작업효율을 향상시키고 작업중 트러블이 야기되지 않을 뿐만 아니라, 생산성 향상도 이루어지는 타이어 제조시 반제품 권출 대차와 권출 성형드럼의 스트립 속도 동기장치를 제공함에 그 목적이 있다.Therefore, the present invention has been invented to solve the conventional problems as described above, the semi-finished product such as rubber strips and liner paper is unwound in the trolley and wound at a more accurate speed when wound on the molding drum to improve the work efficiency and trouble during work It is an object of the present invention to provide a semi-product unloading bogie and strip speed synchronizing device for unwinding drums in the manufacture of tires that not only cause this but also improve productivity.

상기와 같은 목적을 달성하기 위한 본 발명은 반제품 스트립 권출대차와 라이너 스풀 등을 갖추고 클러치와 브레이크가 설치된 렛오프 스테이션에서 반제품 스트립과 라이너를 서비서를 통해 성형 드럼쪽으로 공급하여 이 성형드럼에 권취시키도록 이루어진 스트립 이동장치에 있어서, 상기 라이너를 구동시키는 구동롤러는 별도의 구동모터에 의해 회동되되 이 라이너의 양측면에서 일정 간격으로 연속형성된 간격구멍들에 대응되어 끼워지는 간격 원주돌기 들이 형성되어 이루어진 구조로 되어 있다.In order to achieve the above object, the present invention provides a semi-finished strip unloading bogie and a liner spool and the like to supply a semi-finished strip and a liner to a forming drum through a servicer at a let-off station equipped with a clutch and a brake so as to be wound around the forming drum. In the strip moving device made of, the drive roller for driving the liner is rotated by a separate drive motor is formed in the structure is formed in the interval circumferential protrusions that are fitted in correspondence to the gap holes formed at regular intervals on both sides of the liner It is.
