인너라이너 절단장치{Apparatus for Cutting the Inner-Liner}Inner Liner Cutting Device {Apparatus for Cutting the Inner-Liner}

본 발명은 타이어의 구성재료 중에 하나인 인너라이너를 절단하는 장치에 관한 것으로, 특히 나이프의 가압력을 이용하여 인너라이너를 절단하도록 되어 보다경제적이면서 유지보수가 용이함은 물론, 재료의 오버랩 조인트 작업시 공기입에 의한 불량을 방지할 수 있도록 된 인너라이너 절단장치에 관한 것이다.The present invention relates to an apparatus for cutting an inner liner, which is one of the tire constituent materials, and in particular, the inner liner is cut by using a pressing force of a knife, which is more economical and easier to maintain, and also allows air to work when overlapping materials. The present invention relates to an inner liner cutting device capable of preventing defects caused by mouth.

주지된 바와 같이 인너라이너는 튜브리스타이어(Tubeless Tire)에 사용되는 타이어 구성재료 중에 하나로써, 타이어의 카카스 코드층 내측에 부착되어 타이어 내부의 공기가 누설되지 않도록 하기 위해 사용되는 특수 고무층이다.As is well known, the innerliner is one of tire constituent materials used for a tubeless tire, and is a special rubber layer which is attached to a carcass cord layer of a tire to prevent leakage of air inside the tire.

이러한 인너라이너는 타이어 제조 공정상 소정의 크기로 절단되어 사용되는데, 현재 사용되고 있는 인너라이너 절단장치는 크게 가열된 나이프를 사용하는 방식과 초음파 나이프를 사용하는 방식 및 로터리 나이프를 사용하는 방식으로 나누어 볼 수 있다.This inner liner is cut and used to a predetermined size in the tire manufacturing process. Currently, the inner liner cutting device is divided into two types: a large heated knife, an ultrasonic knife, and a rotary knife. Can be.

그러나 종래의 절단장치는 각각 다음과 같은 문제점이 갖고 있는데, 먼저 가열된 나이프를 사용하는 방식의 경우에는 인너라이너 절단 후 절단면이 불규칙하고 부분적인 고무 스코치의 발생 우려가 높은 문제점이 있으며, 또한 도 4에서 보는 바와 같이 절단 후 인너라이너(100)를 드럼(101)에 권취한 다음 오버랩 조인트(Over-Lab Joint) 작업시 절단 각도에 의해 공기입 발생이나 조인트 단차가 발생되는 문제점이 있었다.However, the conventional cutting device has the following problems, respectively, in the case of using a heated knife first, there is a problem that the cutting surface is irregular and partial rubber scorch after cutting the inner liner, there is a high concern, also Figure 4 As shown in the figure, after the inner liner 100 was wound around the drum 101 after cutting, there was a problem in that pneumatic generation or joint step occurred due to the cutting angle during the over-lab joint operation.

그리고 초음파 나이프를 사용하는 방식의 경우에는 초기 투자비 및 유지보수 비용이 많이 들어가는 문제점이 있었으며, 마지막으로 로터리 나이프를 사용하는 경우에는 절단 잔류물이 발생됨에 따른 처리문제 및 설비 오염에 의한 불량 발생의 문제점 있었다.In the case of using the ultrasonic knife, there was a problem that the initial investment cost and the maintenance cost were high. Finally, when using the rotary knife, there was a problem of treatment caused by cutting residues and defects caused by equipment contamination. there was.

이에 본 발명은 상기와 같은 제반 문제점들을 해결하기 위해 발명된 것으로, 경제적이고 유지보수가 용이함은 물론, 인너라이너의 절단면 형상을 향상시켜 오버랩 조인트 작업시 공기입에 의한 불량을 방지할 수 있도록 된 인너라이너 절단장치를 제공하는데 그 목적이 있다.The present invention has been invented to solve the above problems, the inner and economical and easy to maintain, as well as to improve the cutting surface shape of the inner liner to prevent defects due to pneumatic during overlap joint work It is an object to provide a liner cutting device.

상기와 같은 목적을 달성하기 위한 본 발명은, 지지프레임의 상부에 실린더가 설치되고, 이 실린더의 좌/우측에는 가이드바가 구비되며, 이 가이드바 및 실린더의 끝단이 나이프의 상부와 연결부재 및 고정부재를 매개로 부착되고, 이 나이프의 하부에는 엔빌이 구비되어 이루어진다.The present invention for achieving the above object, the cylinder is installed on the upper portion of the support frame, the left and right side of the cylinder is provided with a guide bar, the end of the guide bar and the cylinder is connected to the top of the knife and the fixing member It is attached via a member, and an anvil is provided in the lower part of this knife.

이하 본 발명을 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 인너라이너 절단장치의 정면도이고, 도 2는 본 발명에 따른 인너라이너 절단장치의 측면도이며, 도 3은 본 발명에 따른 인너라이너 절단장치에 의해 절단된 인너라이너의 절단면과 드럼에 권취된 모습을 도시한 단면도이다.1 is a front view of the inner liner cutting device according to the present invention, Figure 2 is a side view of the inner liner cutting device according to the invention, Figure 3 is a cut surface of the inner liner cut by the inner liner cutting device according to the invention and It is sectional drawing which shows the state wound up by the drum.

본 발명은 지지프레임(1)의 상부에 실린더(2)가 설치되고, 이 실린더(2)의 좌/우측에는 가이드바(3)가 구비되며, 이 가이드바(3) 및 실린더(2)의 끝단이 나이프(5)의 상부와 연결부재(4) 및 고정부재(9)를 매개로 부착되고, 상기 나이프(5)의 하부에는 엔빌(Anvil;6)이 구비되어 이루어진다.In the present invention, the cylinder 2 is installed on the upper part of the support frame 1, and the guide bar 3 is provided on the left and right sides of the cylinder 2, and the guide bar 3 and the cylinder 2 are provided. The end is attached to the upper portion of the knife 5 via the connecting member 4 and the fixing member 9, the lower portion of the knife 5 is provided with an anvil (Anvil) (6).

여기서 상기 나이프(5)의 끝단이 이루어는 각(a)은 130°~ 150°사이이며, 바람직하기로는 135°이다.Here, the angle (a) of the end of the knife 5 is between 130 ° and 150 °, preferably 135 °.

그리고 상기 나이프(5)가 인너라이너(8)에 가하는 압력은 7kgf이며 그 시간은 10초 이내가 바람직하다.The pressure applied to the inner liner 8 by the knife 5 is 7 kgf, and the time is preferably within 10 seconds.

이하 본 발명에 따른 인너라이너 절단장치의 작동을 상세히 설명한다.Hereinafter, the operation of the innerliner cutting device according to the present invention will be described in detail.

인너라이너(8) 반제품이 이송대(17)를 따라 나이프(5)와 엔빌(6) 사이에 위치하게 되면 상기 실린더(2)의 작동에 의해 나이프(5)가 하강되는데, 이때 나이프(5)의 양측에 구비된 가이드바(3)에 의해 나이프(5)는 정확하게 수직하방으로 하강하게 된다.When the inner liner 8 semi-finished product is positioned between the knife 5 and the anvil 6 along the feed table 17, the knife 5 is lowered by the operation of the cylinder 2, where the knife 5 By the guide bar (3) provided on both sides of the knife (5) is accurately lowered vertically down.

이후 인너라이너(8)는 실린더(2)의 확장에 따른 나이프의 압력(7kgf)에 의해 소정시간(10초 이내)이 경과되면 절단되는데, 도 3에서 보는 바와 같은 절단면을 갖으면서 절단되게 된다.Thereafter, the inner liner 8 is cut when a predetermined time (within 10 seconds) has elapsed by the pressure of the knife (7 kgf) according to the expansion of the cylinder 2, and is cut while having a cutting surface as shown in FIG.

이렇게 절단된 인너라이너(8)는 후속공정에서 드럼(10)에 권취된 후 오버랩 조인트 작업시 인너라이너(8)가 접하는 부위의 형상이 종래의 그것에 비해 공기가 유입되기 어려운 형상을 가짐에 따라 공기입에 의한 불량을 방지할 수 있다.The inner liner 8 cut in this manner is wound around the drum 10 in a subsequent process, and thus the shape of a portion where the inner liner 8 is in contact with the inner liner 8 during the overlap joint operation has a shape that is less likely to allow air to enter the conventional air. The defect by the mouth can be prevented.

이상 설명한 바와 같이 본 발명에 따르면, 나이프의 가압력에 의해 인너라이너가 절단되도록 구성되어 종래의 절단장치에 비해 경제적이고 유지보수 용이함은 물론, 인너라이너의 절단면 형상이 향상되어 공기입에 의한 불량을 방지할 수 있는 효과가 있다.As described above, according to the present invention, the inner liner is configured to be cut by the pressing force of the knife, which is economical and easy to maintain compared to the conventional cutting device, and the cutting surface shape of the inner liner is improved to prevent defects caused by pneumatics It can work.
