Description
본 발명은 타이어의 제조공정 중 반제품 조립공정인 성형공정에서 타이어 반제품을 절단하는 절단장치에 관한 것으로, 보다 상세하게는 절단장치에서 타이어반제품을 절단하여 타이어성형기의 성형드럼에 반제품을 부착할 때, 조인트가 타이어의 원주상에 일정한 간격을 두고 분포하도록 타이어의 반제품을 절단하는 장치에 관한 것이다.The present invention relates to a cutting device for cutting a semi-finished product in the molding process, which is a semi-finished assembly process of the manufacturing process of the tire, and more particularly, when the semi-finished product is cut by the cutting device to attach the semi-finished product to the forming drum of the tire molding machine A device for cutting semi-finished products of a tire such that the joints are distributed at regular intervals on the circumference of the tire.
타이어는 정련공정, 압출공정, 압연공정, 비드공정, 재단공정, 포켓공정, 성형공정, 가류공정을 거쳐 완성된다. 여기서, 재단공정은 압연공정을 거친 코드지를 사선방향 또는 직각방향으로 절단하는 작업으로서 필요한 폭과 각도로 절단한 다음, 이것을 연속적으로 연결한 후에 권취하여 다음공정으로 공급해주는 공정이다. 재단공정을 거친 코드지는 일정한 길이로 절단되어진 것을 연속적으로 연결하여 구성되므로 코드지의 연결부위가 오버랩(overlap)되어 다른 부분보다 두꺼워지게 된다. 이렇게 두꺼워진 부위를 재단조인트라고 부른다.Tires are completed through refining, extrusion, rolling, beading, cutting, pocketing, forming and vulcanization. Here, the cutting process is a process of cutting the cord paper after the rolling process in an oblique direction or a right angle direction, is cut at the required width and angle, and then continuously connected to it and wound and supplied to the next process. Since the cord paper, which has been cut, is formed by continuously connecting the cut paper to a certain length, the connection part of the cord paper overlaps and becomes thicker than other parts. This thickened area is called a cutting joint.
한편, 성형공정은 전 공정인 압출공정, 압연공정, 비드공정, 재단공정, 포켓공정에 의해 가공처리된 반제품이 타이어성형기에 운반되어져 그린타이어(green tire)가 만들어지는 공정이다. 그린타이어의 성형공정에서는, 먼저 반제품 압출공정에서 통상의 릴 카트리지로 반제품을 권취한 후, 이 릴 카트리지를 타이어성형기의 반제품 공급장치에 장착하여 반제품을 일정한 속도와 인장력으로 송출한다. 송출한 반제품을 통상의 이송컨베이어로 이동시키면서 이송컨베이어 상에 설치한 길이 측정장치로 반제품의 길이를 측정하여 모터로 구동되는 절단기에 의해 소정의 길이로 절단한다. 소정의 길이로 절단된 반제품을 공급컨베이어에 의해 타이어성형기의 성형드럼 쪽으로 운반하며, 공급컨베이어의 이송속도를 성형드럼의 회전속도와 동일하게 하여 성형드럼에 이 반제품이 자동으로 감기게 하여 그 중심부위를 가압하여 조립체로 제작한다. 반제품의 절단된 선단부가 서로 접합해서 그린타이어가 만들어지게 되는데 절단된 부위가 연결되어 다른 부위보다 두꺼워지는 부분을 성형조인트라고 부른다. 특히, 카카스 플라이의 성형조인트는 다른 부분에 비해 거의 2배에 가까운 두께를 가지게 된다.Meanwhile, the molding process is a process in which a semi-finished product processed by an extrusion process, a rolling process, a bead process, a cutting process, and a pocket process, which is a whole process, is transported to a tire molding machine to make a green tire. In the molding process of the green tire, first, the semi-finished product is wound by a normal reel cartridge in the semi-product extrusion process, and then the reel cartridge is mounted on the semi-finished product supply apparatus of the tire molding machine, and the semi-finished product is sent out at a constant speed and tensile force. While transferring the semifinished product sent out to a normal conveying conveyor, the length of the semifinished product is measured by a length measuring device installed on the conveying conveyor and cut into a predetermined length by a motor driven cutter. The semi-finished product cut to the predetermined length is conveyed to the molding drum of the tire molding machine by the supply conveyor, and the feeding speed of the supply conveyor is the same as the rotation speed of the molding drum so that the semi-finished product is automatically wound on the molding drum. Press to produce the assembly. The cut ends of the semi-finished products are joined to each other to make green tires. The parts where the cut parts are connected and become thicker than other parts are called molding joints. In particular, the molding joint of the carcass ply is almost twice as thick as the other parts.
이렇게 반제품 자체가 가지고 있는 재단조인트와 반제품을 성형할 때 생기는 성형조인트로 인해서 다음과 같은 문제점이 발생할 수 있다.Thus, the following problems may occur due to the cutting joints generated by the semi-finished products and the cutting joints owned by the semi-finished products themselves.
타이어를 성형할 때 재단조인트가 있는 부위가 오버랩되어서 성형조인트가 되어 재단조인트와 성형조인트가 서로 겹쳐지는 경우와 재단조인트가 있는 부위와 근접한 부분이 오버랩되어 성형조인트가 만들어져서 재단 조인트와 성형조인트가 서로 근접하는 경우에 타이어의 균일성을 저하시키게 된다.When the tire is molded, the part where the cutting joint is overlapped becomes a molding joint, and the cutting joint and the molding joint overlap each other, and the part close to the part with the cutting joint is overlapped to form a molding joint. In the case of close proximity to each other, the uniformity of the tire is reduced.
타이어는 원주 어느 방향이나 같은 질량을 가지고 있어야 좋은 품질의 타이어가 되는 것인데 이러한 균일성 불량이 고성능 타이어의 조종성을 저하시키게 되는 것이다.Tires must have the same mass in either direction of the circumference to be of good quality tires. This poor uniformity degrades the maneuverability of high performance tires.
따라서, 드럼상에 재단조인트와 성형조인트를 일정한 간격으로 분포시켜서 타이어의 균일성을 향상시키느냐 혹은 재단조인트를 얼마나 최소화시키느냐에 따라 타이어의 품질에 막대한 영향을 주는 것이다.Therefore, by distributing the cutting joint and the molding joint on the drum at regular intervals, the tire quality is greatly influenced by improving the uniformity of the tire or minimizing the cutting joint.
만약 타이어에 재단조인트는 존재하지 않고 성형조인트만 존재한다면, 타이어성형기에서 타이어를 제작할 때 반제품끼리 부착되는 위치를 변경시킴으로써 반제품의 조인트를 일정하게 분산시키는 것이 가능하다. 그러나, 타이어에는 성형조인트뿐만 아니라 재단조인트도 같이 존재하기 때문에 반제품의 재단조인트와 성형조인트의 간격을 일정하게 분배시키기 어려운 문제점이 있었다.If there are no cutting joints but only molding joints in the tire, it is possible to uniformly disperse the joints of the semi-finished products by changing the positions where the semi-finished products are attached to each other when the tire is manufactured in the tire forming machine. However, since tires include not only molding joints but also cutting joints, it is difficult to uniformly distribute the gap between the cutting joints and the molding joints of semi-finished products.
본 발명은 위와 같은 종래의 문제점을 해결하기 위해 제안된 것으로, 타이어의 반제품을 성형할 때 성형조인트가 생길 반제품의 절단부와 재단조인트가 일정간격을 유지하도록 절단기로 반제품을 절단함으로써 타이어를 성형할 때 반제품의 성형조인트와 재단조인트가 타이어의 원주상에 일정한 간격을 두고 분포하도록 하는데 그 목적이 있다.The present invention has been proposed to solve the above conventional problems, when molding the tire by cutting the semi-finished product by cutting the semi-finished part and the cutting joint of the semi-finished product to be formed when forming the semi-finished product of the tire to maintain a constant interval The purpose is to distribute molding joints and cutting joints of semi-finished products at regular intervals on the circumference of the tire.

이하, 첨부도면을 참조하여 본 발명에 따른 타이어 반제품 절단장치를 보다 상세하게 설명하면 다음과 같다.Hereinafter, the tire semi-finished cutting device according to the present invention with reference to the accompanying drawings in more detail.
본 발명의 조인트 분산이 용이한 타이어 반제품 절단장치(1)는 도 1 및 도 2에 도시된 바와 같이, 후단컨베이어(5), 전단컨베이어(6), 스크랩 보관함(7), 절단기(4), 포토센서(8), 재단조인트 감지롤(1), 재단조인트 감지센서(3), 제어부(10) 등으로 이루어져 있다.Tire semi-finished cutting device 1 is easy to disperse the joint of the present invention, as shown in Figure 1 and 2, the rear conveyor (5), the front conveyor (6), scrap storage box (7), cutter (4), The photo sensor 8, the cutting joint detection roll 1, the cutting joint detection sensor 3, the control unit 10 and the like.
상기 후단컨베이어(conveyor)(5)와 전단컨베이어(6)는 서로 마주보게 설치되어 있고 서보 모터(servo motor)(9)에 의해 구동하며 각각 전진, 후진이 가능하도록 되어 있다. 서보모터(9)는 제어부(10)에 의해 제어된다. 타이어의 반제품이 후단컨베이어(5)로 이송되기 시작하는 부분에는 재단조인트 감지롤(2)이 장착되어 있어 반제품이 후단컨베이어(5) 위를 지나갈 때 재단조인트 감지롤(roll)(2) 아래를 통과하도록 되어 있다. 재단조인트는 다른 부분보다 두껍게 되어 있으므로 재단조인트가 있는 부분이 지나갈 때 재단조인트 감지롤(roll)(2)이 위로 들리게 된다. 재단조인트 감지롤(1)에는 재단조인트 감지롤(1)의 움직임에 의해 감지되는 재단조인트 감지센서(3)가 부착되어 있어 재단조인트 부분이 재단조인트 감지롤(1) 아래로 지나가면 재단조인트 감지센서(3)에 감지되어 제어부(10)에 신호를 보내는 역할을 한다.The rear conveyor (5) and the front conveyor (6) are installed to face each other and are driven by a servo motor (9), and can be moved forward and backward, respectively. The servomotor 9 is controlled by the controller 10. At the point where the semi-finished product of the tire begins to be transferred to the rear conveyor (5), the cutting joint detection roll (2) is mounted so that the semi-finished product passes under the cutting joint detection roll (2) when the semi-finished product passes over the rear conveyor (5). It is meant to pass. Since the cutting joint is thicker than other parts, the cutting joint detection roll 2 is lifted up when the cutting joint passes. The cutting joint detection roll (1) is equipped with a cutting joint detection sensor (3) detected by the movement of the cutting joint detection roll (1) so that the cutting joint portion passes under the cutting joint detection roll (1) to detect the cutting joint. It is detected by the sensor (3) serves to send a signal to the control unit (10).
후단컨베이어(6)의 끝부분에는 포토센서(8)가 장착되어 있어 타이어 반제품의 끝부분이 포토센서(8)에 도달하면 제어부(10)에 신호를 보내는 역할을 한다.At the end of the rear conveyor (6) is equipped with a photosensor (8) serves to send a signal to the control unit 10 when the end of the semi-finished tire reaches the photosensor (8).
후단컨베이어(5)와 전단컨베이어(6) 사이의 상부에는 절단기(4)가 장착되어 있어 후단컨베이어(5) 끝부분까지 반제품이 이송되어져 오면 타이어가 성형될 때 재단조인트와 성형조인트가 만들어질 절단부가 일정한 간격이 되도록 반제품을 절단하는 역할을 한다. 그리고, 타이어의 성형에 필요한 적당한 길이로 반제품을 절단하는 역할도 한다. 후단컨베이어(5)와 전단컨베이어(6) 사이의 하부에는절단기(4)의 위치에 대응해서 스크랩 보관함(7)이 있어 절단기(4)에 의해 잘려진 반제품조각들이 담겨지게 되어 있다.The upper part between the rear conveyor 5 and the front conveyor 6 is equipped with a cutter 4 so that the semi-finished product is transported to the end of the rear conveyor 5 so that the cutting joint and the molding joint are made when the tire is molded. It cuts the semi-finished product at regular intervals. In addition, it also serves to cut the semi-finished product to an appropriate length necessary for molding the tire. In the lower part between the rear conveyor 5 and the front conveyor 6, there is a scrap storage box 7 corresponding to the position of the cutter 4, so that the semi-finished pieces cut by the cutter 4 are contained.
이제 위와 같이 구성된 본 발명에 따른 조인트 분산이 용이한 타이어 반제품 절단장치의 작용을 설명하면 다음과 같다.Now explaining the operation of the tire semi-finished cutting device easy to disperse the joint according to the present invention configured as described above are as follows.
반제품, 예를 들어 제 1, 제 2 바디플라이(bodyply)의 재단조인트는 오버랩 형태로 되어 있어서 다른 부위보다 두껍게 되어 있다. 따라서 재단조인트가 재단조인트 감지롤(2) 아래를 지나게 되면 재단조인트 감지롤(2)이 들어올려지면서 재단조인트 감지센서(3)에 감지되어 신호가 제어부(10)로 보내진다.The cut joints of the semifinished product, for example the first and second bodyplies, are in the form of overlap and are thicker than other parts. Therefore, when the cutting joint passes under the cutting joint detection roll 2, the cutting joint detection roll 2 is lifted up and sensed by the cutting joint detection sensor 3, and a signal is sent to the controller 10.
서보모터(9)로 후단컨베이어(5)를 구동시켜 후단컨베이어(5)로 반제품을 전진시킨다. 반제품이 계속 전진해서 포토센서(8)가 장착된 위치까지 오게 되면 포토센서(8)에 반제품의 끝부분이 감지되어 신호가 제어부(10)로 보내지게 된다. 재단조인트 감지센서(3)와 포토센서(8)는 고정되어 있으므로 재단조인트 감지센서(3)와 포토센서(8) 간의 거리는 일정하다. 그리고, 재단조인트 감지센서(3)에서 보내온 신호를 받는 순간부터 포토센서(8)에서 신호를 받을 때까지 반제품의 이동거리가 측정되어 질 수 있으므로 반제품의 끝부분과 재단조인트 사이의 거리가 계산되어질 수 있게 된다. 그런 다음에, 재단조인트에서부터 성형조인트가 만들어질 절단부까지의 거리가 미리 정해 놓은 일정한 간격이 되도록 제어부(10)에서 신호를 받은 서보모터(9)에 의해 후단컨베이어(5)를 전진시켜 반제품이 전단컨베이어(6)에 걸쳐지도록 한다. 반제품이 정해진 일정거리를 가게 되면 절단기(4)가 작동하여 반제품을 자른다. 그런 다음에 서보모터(9)에 의해 후단컨베이어(5)와 전단컨베이어(6)가 구동하여 각각 후진하게 된다. 그러면 전단컨베이어(6) 위에 걸쳐져 있던 반제품은 이송되어 잘려진 조각이 스크랩 보관함(7)에 자동으로 떨어져서 스크랩 보관함(7)에 반제품 조각들이 모아지게 된다.The rear end conveyor 5 is driven by the servomotor 9 to advance the semifinished product to the rear end conveyor 5. When the semi-finished product is continuously advanced to the position where the photosensor 8 is mounted, the tip of the semi-finished product is detected by the photosensor 8 and a signal is sent to the controller 10. Since the cutting joint detection sensor 3 and the photosensor 8 are fixed, the distance between the cutting joint detection sensor 3 and the photosensor 8 is constant. Since the moving distance of the semifinished product can be measured from the moment of receiving the signal sent from the cutting joint sensor 3 to the signal of the photosensor 8, the distance between the end of the semifinished product and the cutting joint can be calculated. It becomes possible. Then, the rear end conveyor (5) is advanced by the servo motor (9) receiving the signal from the control unit (10) so that the distance from the cutting joint to the cutting portion where the molding joint is to be made is a predetermined interval. To span the conveyor (6). When the semi-finished product goes a predetermined distance, the cutter 4 operates to cut the semi-finished product. Thereafter, the rear stage conveyor 5 and the front conveyor 6 are driven by the servomotor 9 to move backward. Then, the semi-finished product over the shear conveyor (6) is transported and the cut pieces are automatically dropped in the scrap storage box (7) to collect the semi-finished pieces in the scrap storage box (7).
마지막으로 후단컨베이어(5)에 있던 반제품은 정해진 타이어 규격대로 절단되어져서 다음 단계인 타이어 성형작업으로 보내지게 된다. 타이어 성형작업에서 절단부위를 서로 연결해서 타이어를 성형하게 된다.Finally, the semi-finished product in the rear conveyor (5) is cut according to the prescribed tire specifications and sent to the next step of forming a tire. In the tire forming operation, the cut parts are connected to each other to form a tire.
이상 설명한 바와 같이, 본 발명의 조인트 분산이 용이한 타이어 반제품 절단장치에 의하면, 타이어를 성형할 때 생기는 성형조인트 및 재단조인트가 타이어의 원주상에 일정한 간격을 처음에는 두고 분포하도록 타이어의 반제품을 절단해서 조인트를 타이어의 원주상에 골고루 분포시키거나 최소화되도록 함으로써 타이어의 불량을 예방하고 품질을 향상시킬 수 있게 된다.As described above, according to the tire semi-finished product cutting device of the present invention, the semi-finished product of the tire is cut so that the molding joint and the cutting joint, which are produced when the tire is molded, are distributed at regular intervals on the circumference of the tire. Therefore, the joints are evenly distributed or minimized on the circumference of the tire, thereby preventing the failure of the tire and improving the quality.
