반제품 고무시트의 커팅장치{Cutting apparatus of rubber sheet}Cutting device for semifinished rubber sheet

본 발명은 타이어 제조시 압연 공정을 마친 토핑된 고무시트를 정해진 각도와 폭에 따라 절단하는 고무시트의 커팅장치에 관한 것으로, 더욱 상세하게는 스윙 커터를 이용하여 고무시트를 절단함에 따라 설비의 경량화와 커터의 수명 연장 및 큰 절단하중을 구현할 수 있는 반제품 고무시트의 커팅장치에 관한 것이다.The present invention relates to a cutting device of a rubber sheet for cutting a topping rubber sheet after the rolling process in the tire manufacturing according to a predetermined angle and width, and more particularly, to reduce the weight of the equipment by cutting the rubber sheet using a swing cutter The present invention relates to a cutting device for a semi-finished rubber sheet capable of realizing an extended life of a cutter and a large cutting load.

타이어 구성 부품인 벨트, 카카스, 등과 같은 반제품 고무시트는 압연 공정을 끝마치게 되면 재단 공정으로 이동하게 되며 정해진 각도와 폭에 따라 절단되어진 후 롤에 감아져서 다음 공정으로 이동하기 위해 적재되어진다.Semi-finished rubber sheets, such as tire components, belts, carcasses, etc., are moved to the cutting process after finishing the rolling process, cut according to a predetermined angle and width, and then wound on rolls and loaded for moving to the next process.

현재 반제품 고무시트의 재단 공정에서 절단방식은 상하 커팅기를 이용한 수직 커팅 방식인 재단 절단기(Guillotine)를 사용하는바, 이러한 수직 커팅 방식인 재단 절단기를 이용하여 각각의 부재에 맞는 폭 및 각도를 갖는 부재를 얻도록 되어 있었다.In the cutting process of the semi-finished rubber sheet, the cutting method uses a cutting cutter (Guillotine), which is a vertical cutting method using an up-and-down cutter, and a member having a width and an angle suitable for each member using the cutting cutter, which is a vertical cutting method. Was supposed to get.

즉 도 3과 같이 종래 수직 커팅 방식의 재단 절단기는 승, 하강 되어지는 상부 나이프(102)와 고정된 하부 나이프(101)로 이루어져 반제품 고무시트(103)가 투입되면, 상기 상부 나이프(102)가 하강하여 반제품 고무시트(103)를 절단한 후, 이 상부 나이트(102)는 다시 상승하여 원위치로 복귀되어진다.That is, the cutting machine of the conventional vertical cutting method as shown in Figure 3 is composed of the upper knife 102 and the fixed lower knife 101 to be raised and lowered, when the semi-finished rubber sheet 103 is inserted, the upper knife 102 is After lowering and cutting the semi-finished rubber sheet 103, the upper knight 102 is raised again and returned to its original position.

그러나 절단되는 반제품 고무시트(103)의 단면이 상부 나이프(102)의 정도에 따라 품도와 커팅면이 결정되어 지는데, 나이프의 접지면이 커팅 포인트 이외 전면접촉 요인으로 인해 나이프의 마모로 인한 수명을 감소시키는 원인으로 제공되었다.However, the cross-section of the semi-finished rubber sheet 103 to be cut is determined according to the degree of the upper knife 102, the cutting quality and the cutting surface, the ground surface of the knife due to the front contact factors other than the cutting point, the life due to the wear of the knife Served as a cause for the reduction.

또한, 상, 하부 나이프(102, 101)의 갭(Gap) 정도가 매우 중요시되는바, 이 상부 나이프(102)의 변화로 설비정도에 큰 영향을 미치는 문제점도 있었다.In addition, the gap between the upper and lower knives (102, 101) is very important, there is also a problem that the change of the upper knife 102 has a large effect on the installation accuracy.

이에 본 발명은 상기와 같은 종래 문제점을 해결하기 위해 발명된 것으로, 절단시 생기는 진동 및 여타의 변동에 대한 오차를 줄일 수 있을 뿐만 아니라, 설비정도 및 반제품 절단 단면에 대한 품질 확보도 병행할 수 있는 반제품 고무시트의 커팅장치를 제공함에 그 목적이 있다.Therefore, the present invention has been invented to solve the conventional problems as described above, and can reduce the error of vibration and other fluctuations generated during cutting, as well as to ensure the quality of equipment and the quality of the semi-finished cutting section. The object is to provide a cutting device for a semi-finished rubber sheet.

상기와 같은 목적을 달성하기 위한 본 발명은 상, 하부 나이프 사이에 진입된 반제품 고무시트를 절단하는 커팅장치에 있어서, 상기 상부 나이프의 본체는 힌지축을 매개로 스윙 회동하되, 이 힌지축은 볼 베어링으로 구성되어 상기 힌지축의 주축과 공차 갭을 갖도록 구성되어 있다.The present invention for achieving the above object is a cutting device for cutting the semi-finished rubber sheet entered between the upper, lower knife, the main body of the upper knife swings through the hinge axis, the hinge axis is a ball bearing It is configured to have a tolerance gap with the main axis of the hinge axis.

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

도 1은 본 발명에 따른 반제품 고무시트의 커팅장치를 나타낸 측면도이고, 도 2(a), (b)는 도 1의 작동 상태도 이다.1 is a side view showing a cutting device of a semi-finished rubber sheet according to the present invention, Figure 2 (a), (b) is an operating state diagram of FIG.

본 발명은 고정된 하부 나이프(1)와 이동하는 상부 나이프(2) 사이에 반제품 고무시트(3)가 진입되어 이 진입된 반제품 고무시트(3)를 절단하는 커팅장치에 있어서, 상기 상부 나이프(2)의 본체(4)는 힌지축(5)을 지점으로 스윙 회동하되, 이 힌지축(5)은 볼 베어링(6)이 구비되어 상기 힌지축(5)의 주축(7)과 공차 갭(d)을 갖도록 이루어진 구조로 되어 있다.The present invention is a cutting device for cutting the semi-finished rubber sheet (3) enters the semi-finished rubber sheet 3 between the fixed lower knife (1) and the moving upper knife (2), the upper knife ( The main body 4 of 2) swings the hinge shaft 5 to a point, and the hinge shaft 5 is provided with a ball bearing 6 so that the main shaft 7 of the hinge shaft 5 and the tolerance gap ( It has a structure made to have d).

이와 같은 본 발명은 상부 나이프(2)를 갖춘 본체(4)가 링크 힌지축(5)으로 고정되어 있으며, 종래와 같이 상하 직선운동이 아닌 스윙 회동운동에 의해 이 힌지축(5)을 지점으로 상부 나이프(2)가 있는 본체(4)의 원주 끝부분에 힘을 가할 수 있도록 되어 있다.In the present invention as described above, the main body 4 having the upper knife 2 is fixed to the link hinge shaft 5, and the hinge shaft 5 is moved to the point by a swing rotational motion instead of the vertical motion as in the prior art. A force can be applied to the circumferential end of the main body 4 with the upper knife 2.

즉 본 발명은 직선운동을 회전운동으로 전환하여 반제품 고무시트(3)를 도 2의 (a), (b)와 같이 절단한 다음, 바로 원위치로 복원되어 진다.That is, in the present invention, the semi-finished rubber sheet 3 is cut as shown in FIGS. 2A and 2B by converting the linear motion into the rotational motion, and then immediately restored to the original position.

그리고 상기 상부 나이프(2)의 유동을 미세하게 조정할 수 있도록 이 힌지축(5)은 볼 베어링(6)으로 구성된 주축(7)에 공차 갭(d)을 두어 상부 나이프(2)의 본체(4)가 좌우로 움직이면서 나이프 갭 조정을 정밀하게 수행할 수 있다.In order to finely adjust the flow of the upper knife 2, the hinge shaft 5 has a tolerance gap d on the main shaft 7 formed of the ball bearing 6 so as to provide a main body 4 of the upper knife 2. The knife gap adjustment can be precisely performed by moving from side to side.

상기와 같이 본 발명에 따른 반제품 고무시트의 커팅장치는 절단 나이프의 마모를 최소화하여 수명 연장과 절단면의 품질 향상에 기여하고, 또한 설비의 진동 문제를 해결하여 안정된 설비 구축을 갖도록 되어 있다.As described above, the cutting device of the semi-finished rubber sheet according to the present invention minimizes the wear of the cutting knife to contribute to the extension of the life and the quality of the cutting surface, and also to solve the vibration problem of the equipment to have a stable construction of the equipment.

도 1은 본 발명에 따른 반제품 고무시트의 커팅장치를 나타낸 측면도,1 is a side view showing a cutting device of a semi-finished rubber sheet according to the present invention,

도 2(a),(b)는 본 발명에 따른 커팅장치의 작동 상태 측면도,Figure 2 (a), (b) is a side view of the operating state of the cutting device according to the invention,
