Field of the Invention The present invention relates to a rubber strip conveying feeder for conveying extruded rubber strips for manufacturing sidewalls, rim cushions, and treads among semi-finished tires, from extruders to forming drums. The present invention relates to a rubber strip conveying and feeding device for reducing the amount of deformation by shortening the operating time and maintaining tension to the applicator attaching the extruded rubber strip to the forming drum.

타이어 반제품인 사이드 월, 림쿠션, 트레드 등을 압출기에서 압출되는 고무스트립이 일정한 길이로 압출되어 이들의 성형작업시 성형작업 능률을 향상시켜 주기 위해 성형드럼에서 일차적으로 부착 조인트하여 주도록 되어 있다.Side strips, rim cushions and treads, which are semi-finished tires, are extruded from the extruder to a certain length so that they are first attached and jointed in the forming drum to improve the molding efficiency during their molding.

종래 압출기에서 압출된 반제품 고무스트립을 성형드럼에 직접 부착시킬 때 중간에 카렌다(Calender)를 이용하기 때문에 이 카렌다가 차지하는 공간이 커서 작업작동 사이클이 클 뿐만 아니라, 압출기의 토출속도가 성형드럼의 회전속도가 동일한 등속상태를 유지해야 하기 때문에 압출기의 이상 발생시 곧바로 성형기의 작업정지로 이어지는 문제점이 제기되어 왔다.When attaching the semi-finished rubber strip extruded from the conventional extruder directly to the molding drum, calendar is used in the middle, so the space occupied by this calendar is not only large, but also a large working cycle, and the ejection speed of the extruder is the rotation of the molding drum. Since the speed must be maintained at the same constant state, a problem has been raised that leads to the stoppage of the molding machine when an abnormality occurs in the extruder.

이에 본 발명은 상기와 같은 종래 문제점을 해결하기 위해 발명된 것으로, 압출기에서 토출된 고무스트립을 운반벨트를 이용하여 어플리케이터에 직접 공급하여 성형드럼에 고무스트립을 부착시킴에 따라 작동시간 단축과 자동 성력화가 이루어지고 공급되는 고무스트립의 장력유지로 타이어의 균일성 향상에도 기여하는 고 무스트립 운반 공급장치를 제공함에 그 목적이 있다.Therefore, the present invention was invented to solve the conventional problems as described above, by supplying the rubber strip discharged from the extruder directly to the applicator using a transport belt to attach the rubber strip to the molding drum to shorten the operating time and automatic performance The purpose of the present invention is to provide a rubber strip conveying and feeding device that contributes to improving the uniformity of the tire by maintaining the tension of the rubber strip to be supplied.

그리고 도면 중 미설명 부호, 17은 커터이고, 18은 압착롤러이다.In the drawings, reference numeral 17 denotes a cutter, and 18 denotes a pressing roller.

이어 본 발명의 작동상태를 설명한다.Next, the operating state of the present invention will be described.

먼저 도 1과 도 2에 도시된 바와 같이 압출기(1)에 토출된 고무스트립(2)은 무한벨트 방식으로 연속적으로 도는 운반벨트(9)에 안착되어 윈치 저장 루프부(5)의 롤러(7a)들을 거쳐 어플리케이터(4)의 선단 압착롤러(8)를 통하여 성형드럼(3)에 부착되면서 일정 규격으로 커터(17)에 의해 절단된다.First, as shown in FIGS. 1 and 2, the rubber strip 2 discharged to the extruder 1 is seated on a conveying belt 9 which continuously turns in an endless belt manner, and thus the roller 7a of the winch storage loop part 5. Are attached to the forming drum 3 via the tip pressing roller 8 of the applicator 4 via the applicators 4, and are cut by the cutter 17 to a predetermined standard.

여기서 상기 어플리케이터(4)는 최초 도 4의 대기상태에 있다가 하단 이동부(6b)에 의해 1차 이동하고 상단 이동부(6a)에 의해 2차 이동되어 운반벨트(9)에 안착된 고무스트립(2)을 도 5의 작동상태와 같이 성형드럼(3)과 접촉시키게 되는바, 이때 상기 상단 이동부(6a)의 모터(13)와 실린더(14)에 의해 2단 전진되는 선단 압착롤러(8)는 회전 장력롤러(16)들과 연관 작동하여 운반벨트(9)의 장력을 조절하면서 이 운반벨트(9)에 안착된 고무스트립(2)을 회전하는 성형드럼(3)에 도 3과 같이 축선회하는 압착롤러(18)와 함께 부착시키게 되고, 빈 운반벨트(9)는 회전 장력롤러(16)와 가이드 롤러(15)를 거쳐 윈치 저장 루프부(5)의 다른 롤러(7b)를 통하여 압출기(1) 쪽으로 이동되어 새로운 압출고무 스트립(2)을 받도록 되어 있다.Here, the applicator 4 is initially in the standby state of FIG. 4, and is primarily moved by the lower moving part 6b and secondly moved by the upper moving part 6a to be seated on the carrying belt 9. (2) is brought into contact with the forming drum (3) as shown in the operating state of Figure 5, wherein the front end of the pressing roller (2) advanced two stages by the motor (13) and the cylinder (14) of the upper moving part (6a) 8) in conjunction with the rotating tension rollers 16 to adjust the tension of the conveying belt (9) while rotating the rubber strip (2) seated on the conveying belt (9) to the forming drum (3) Along with the pressing roller 18 pivoting together, the empty conveying belt 9 is connected to the other roller 7b of the winch storage loop part 5 via the rotating tension roller 16 and the guide roller 15. It is moved through the extruder 1 to receive a new extruded rubber strip 2.

상기 성형드럼(3)에 하나의 고무스트립(2)의 부착작업이 끝나면, 어플리케이터(4)는 도 5의 작동상태에서 도 4의 대기상태로 원위치 후진 이동하게 되는데, 이때에는 앞선 동작의 역순으로 작용한다.After the attachment of one rubber strip 2 to the forming drum 3 is completed, the applicator 4 moves backward from the operating state of FIG. 5 to the standby state of FIG. 4, in this case in the reverse order of the preceding operation. Works.

따라서 본 발명은 성형드럼(3)에 고무스트립(2)을 부착하는 어플리케이터(4)의 선단에 압착롤러(18)를 부착하여 고무스트립(2)의 변형량을 최소화하고, 상기 고무스트립(2)을 운반하는 운반벨트(9) 장력유지를 위해 회전 장력롤러(16) 등이 설치되어 있으며, 압출기(1)에서 자동 토출되는 고무스트립(2)이 성형드럼(3) 쪽으로 연속 공급되어 자동생산이 가능하도록 되어 있다.Therefore, the present invention attaches the pressing roller 18 to the tip of the applicator 4 attaching the rubber strip 2 to the forming drum 3 to minimize the amount of deformation of the rubber strip 2, the rubber strip 2 Rotating tension roller 16 or the like is installed to maintain the tension of the conveying belt 9, and the rubber strip 2 discharged automatically from the extruder 1 is continuously supplied toward the forming drum 3 so that the automatic production is performed. It is possible.

상기와 같이 본 발명에 따른 고무스트립 운반 공급장치는 성형드럼으로 공급되는 고무스트립의 변형량을 최소화하여 타이어 균일화에 도움을 주며, 작업시간 단축으로 생산성 향상과 자동 성력화가 이루어지는 효과를 지닌다.As described above, the rubber strip conveying and supplying device according to the present invention minimizes the amount of deformation of the rubber strip supplied to the forming drum, thereby helping to uniformize the tire, and have an effect of improving productivity and increasing automatic performance by shortening the working time.
