주지된 바와 같이 타이어 제조시에는 원재료인 천연고무(Natural Rubber)에 각종 화학약품을 적정 비율로 배합시킨 다음, 이 배합된 덩어리상태의 고무를 얇은 시이트상태로 압연시키 다른공정에서 사용될 반제품 상태로 반출시켜야 하는 바, 이와 같이 덩어리상태로 된 고무를 얇은 시이트상태로 압연시키도록 하는 종래의 설비는 제3도에 도시된 바와 같이, 롤러다이압출기(21)의 헤드부(22)전방에 상/하부 캘린더롤(23,23')이 배치되고, 이 상/하부캘린더롤(23,23')의 하부배출구쪽에 압연된 고무시이트(24)를 이송하는 인출컨베이어(25)가 배치된 구조를 이루고 있다.As is well known, in the manufacture of tires, various chemicals are mixed in natural rubber, which is a raw material, in an appropriate ratio, and then the blended lumped rubber is rolled in a thin sheet state and taken out as a semi-finished product for use in another process. As shown in FIG. 3, the conventional equipment for rolling the agglomerated rubber into a thin sheet state is provided with a top / bottom in front of the head portion 22 of the roller die extruder 21. As shown in FIG. The calender rolls 23 and 23 'are arranged, and the drawing conveyor 25 which conveys the rolled rubber sheet 24 is arrange | positioned at the lower discharge side of this upper and lower calendar rolls 23 and 23'. .

따라서 상기 롤러다이압출기(21)에 의해 압송된 덩어리상태의 고무가 헤드부(22)를 통해 상/하부 캘린더롤(23,23')로 이송되면 이 상/하부캘린더롤(23,23')이 회전되면서 상기 덩어리상태의 고무(26)를 가압시켜 얇은 시이트상태의 고무시이트(24)로 압연시켜 배출시키고, 이렇게 압연되어 배출된 고무시이트(24)는 상기 상/하부캘린더롤(23,23')의 하부에 마련된 인출컨베이어(25)를 타고 이송되게 된다.Therefore, when the rubber in the lump state pushed by the roller die extruder 21 is transferred to the upper and lower calender rolls 23 and 23 'through the head portion 22, the upper and lower calender rolls 23 and 23'. While rotating, the rubber 26 in the agglomerated state is pressed and rolled into a thin sheet rubber sheet 24 to be discharged. The rolled and discharged rubber sheet 24 is the upper and lower calendar rolls 23 and 23. It is carried by the withdrawal conveyor 25 provided in the lower portion of ').

그러나 덩어리상태의 고무가 상/하부캘린더롤(23,23')을 통해 배출될 때 고무의 고유특성상 배출되는 고무시이트(24)가 상부캘린더롤(23)또는 하부캘린더롤(23')의 표면에 달라붙게 되어 인출컨베이어(25)로 원할하게 적재되지 않게 되는 공정트러블이 종종 발새오디었는데, 특히 상기 롤러다이압출기(21)로 부터 공급되는 고무의 종류가 변경될 경우에는 상기 상/하부 캘린더롤(23,23')을 통해 고무시이트(24)를 최초 배출시킬 때 롤표면에 이전의 고무시이트(24)가 달라붙게 된다는 문제가 있었다.However, when the lumped rubber is discharged through the upper and lower calendar rolls 23 and 23 ', the rubber sheet 24 discharged due to the inherent properties of the rubber is the surface of the upper calendar roll 23 or the lower calendar roll 23'. Process trouble that sometimes sticks to the drawer conveyor 25 and is not loaded smoothly is often found, especially when the type of rubber supplied from the roller die extruder 21 is changed, the upper and lower calender rolls. When the rubber sheet 24 was first discharged through the 23 and 23 ', there was a problem that the previous rubber sheet 24 was stuck to the roll surface.

따라서 작업자는 상/하부캘린더롤(23,23')표면에 달라붙는 고무시이트(24)를 손으로 잡아떼어서 인출컨베이어(25)상으로 유도시켜야만 하였는데, 이와 같은 경우에는 동작중인 회전체에 작업자가 손을 대야 하므로 안전사고발생의 위험이 뒤따르는 문제점이 있었다.Therefore, the worker had to pull the rubber sheet 24 sticking to the upper and lower calendar rolls 23 and 23 'by hand and guide it onto the takeout conveyor 25. In this case, Since there was a need to touch, there was a problem that the risk of a safety accident follows.

이에 본 고안은 상기와 같은 제반 문제점을 해소하기 위해 안출된 것으로 ,롤러다이압출기를 통해 압송된 고무를 압연시키는 상/하부 캘린더롤상에 이형제인 파우더를 적절하게 뿌려주는 분무장치를 마련하여, 압연되는 고무시이트가 롤표면에 달라붙지 않도록 하여 캘린더롤을 통한 압연공정이 원활하게 이루어지도록 함과 더불어, 작업자의 안전이 확보될 수 있도록 된 이형제 분무장치를 갖춘 롤러다이압출기를 제공함에 그 목적이 있다.The present invention has been devised to solve the above problems, to provide a spray device for appropriately spraying the powder of the release agent on the upper / lower calender roll rolling the rubber conveyed through the roller die extruder, It is an object of the present invention to provide a roller die extruder having a release agent spraying device that can secure the operator's safety while preventing the rubber sheet from sticking to the roll surface.
