Description
본 발명은 타이어 성형공정에서 반제품(Semifinished Product)을 절단하는 장치에 관한 것으로, 보다 상세하게는 타이어를 성형할 때 반제품 절단부위 간의 연결부분인 성형조인트의 접착력을 높이기 위해 반제품 절단부위에 균일하게 열을 가하기 위한 반제품 절단장치에 관한 것이다.The present invention relates to a device for cutting a semifinished product in a tire forming process, and more particularly, to uniformly heat the semi-finished cutting part to increase the adhesive force of the molding joint, which is a connection part between the cutting parts of the semi-finished product when molding the tire. It relates to a semi-finished cutting device for applying a.
일반적으로 타이어는 정련공정, 압출공정, 압연공정, 비드공정, 재단공정, 포켓공정, 성형공정, 가류공정을 거쳐 완성된다. 여기서, 성형공정은 전 공정인 압출공정, 압연공정, 비드공정, 재단공정, 포켓공정에 의해 가공처리된 반제품이 타이어 형기에 운반되어져 그린타이어(Green Tire)가 만들어지는 공정이다.Generally, tires are completed through a refining process, an extrusion process, a rolling process, a bead process, a cutting process, a pocket process, a molding process, and a vulcanization process. Here, 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 molder to create a green tire.
이러한 성형공정에서는, 먼저 압출공정에서 통상의 릴 카트리지(Reel Cartridge)로 반제품을 권취한 후, 릴 카트리지를 타이어 성형기의 반제품 공급장치에 장착하여 반제품을 일정한 속도와 인장력으로 송출한다. 송출한 반제품을 통상의 이송컨베이어로 이동시키면서 이송컨베이어 상에 설치한 길이 측정장치로 반제품의 길이를 측정하여 가이드판 위에 반제품이 대기하고 있을 때에 나이프(Knife)를 사용하여 소정의 길이로 절단한다.In such a molding step, first, the semi-finished product is wound by a normal reel cartridge in an extrusion process, and then the reel cartridge is mounted on the semi-finished product supply apparatus of the tire molding machine to send the semi-finished product at a constant speed and tensile force. The semi-finished product is measured by a length measuring device installed on the conveying conveyor while moving the semi-finished product sent out to a normal conveying conveyor. When the semi-finished product is waiting on the guide plate, the semi-finished product is cut into a predetermined length.
이렇게 소정의 길이로 절단된 반제품은 공급컨베이어에 의해 타이어 성형기의 성형드럼 쪽으로 운반된다. 운반된 반제품은 성형드럼에 자동으로 감겨진 다음, 반제품의 절단된 선단부를 서로 접합하여 가압함으로써 그린타이어가 제작된다.The semifinished product cut to the predetermined length is conveyed to the forming drum of the tire forming machine by the supply conveyor. The conveyed semifinished product is automatically wound on the forming drum, and then the green tires are produced by joining and pressing the cut ends of the semifinished product together.
여기서, 반제품의 절단된 부위가 접합되면서 다른 부위보다 두꺼워지는 부분이 생기는 데 이러한 부위를 성형조인트(joint)라고 부른다. 성형조인트는 반제품의 절단된 부위를 가압함으로써 만들어지는 것이기 때문에 접착력이 약해질 수 있고, 이로 인해 성형공정 및 가류공정 후에 성형조인트가 벌어지거나 갈라지는 문제점이 있었다.Here, the cut portion of the semi-finished product is a portion that is thicker than the other portion is bonded, this portion is called a molding joint (joint). Since the molding joint is made by pressing the cut part of the semi-finished product, the adhesive strength may be weakened, and thus, the molding joint may be opened or cracked after the molding process and the vulcanization process.
본 발명은 상기한 문제점을 해결하기 위해 제안된 것으로, 타이어를 성형할때 반제품 절단부위 간의 부착이 잘 이루어지도록 하여 반제품 절단부위 간의 연결부분인 성형조인트의 접착력을 높이는데 그 목적이 있다.The present invention has been proposed to solve the above problems, and has an object to increase the adhesive force of the molding joint, which is a connection between the semi-finished cutting parts so that the attachment between the semi-finished cutting parts is made well when molding the tire.

이하, 첨부도면을 참조하여 본 발명에 따른 반제품 절단장치를 보다 상세히 설명하면 다음과 같다.Hereinafter, the semi-finished cutting device according to the present invention with reference to the accompanying drawings in more detail.
본 발명의 반제품 절단장치는 도 1 에 도시된 바와 같이, 전단컨베이어(2)와 후단컨베이어(3)가 서로 마주보게 설치되어 각각 전진, 후진이 가능하도록 되어 있다. 전단컨베이어(2)와 후단컨베이어(3) 위로는 타이어의 반제품(1)이 이송된다. 전단컨베이어(2)와 후단컨베이어(3) 사이의 상부에는 나이프(knife)(4)가 설치되어 있어 후단컨베이어(3) 끝부분까지 반제품이 이송되어져 오면 타이어의 성형에 필요한 적당한 길이로 반제품(1)을 절단한다.In the semi-finished cutting device of the present invention, as shown in Figure 1, the front conveyor (2) and the rear conveyor (3) are installed to face each other to enable forward and backward, respectively. The semi-finished product 1 of the tire is transferred onto the front conveyor 2 and the rear conveyor 3. A knife (4) is installed at the upper part between the front conveyor (2) and the rear conveyor (3). When the semi-finished product is transferred to the end of the rear conveyor (3), the semi-finished product (1) Cut)
나이프(4)의 하부에는 가이드판(5)이 설치되어 반제품(1)을 절단할 때 나이프(4)를 받쳐주는 역할을 한다. 가이드판(5)의 가운데 부분에는 가열봉 삽입홈(6)이 형성되어 가열봉(7)이 삽입된다. 가열봉(7)은 구리로 된 중공원통형의 막대에코일(8)이 감겨져 있는 쇠 막대가 삽입된다. 코일(8)은 쇠막대의 좌, 우측보다 가운데 부분에 더 조밀하게 감겨져 있어 가열봉(7)의 온도편차를 줄여 가열봉(7) 전체가 균일하게 가열되도록 한다. 코일(8)의 양끝은 온도조절장치(미도시)와 전선(미도시)으로 연결되어 있어 전선(미도시)을 통해 가열봉(7)으로 열이 전달된다.Guide plate 5 is installed in the lower portion of the knife 4 serves to support the knife 4 when cutting the semi-finished product (1). The heating rod insertion groove 6 is formed in the center portion of the guide plate 5 to insert the heating rod 7. The heating rod (7) is inserted into the iron rod, the coil (8) is wound around the hollow hollow cylindrical rod. The coil 8 is more tightly wound on the center portion than the left and right sides of the iron rod to reduce the temperature deviation of the heating rod 7 so that the entire heating rod 7 is uniformly heated. Both ends of the coil 8 are connected to a temperature controller (not shown) and an electric wire (not shown) so that heat is transferred to the heating rod 7 through the electric wire (not shown).
위와 같이 구성된 본 발명에 따른 반제품 절단장치의 작용을 설명하면 다음과 같다.Referring to the operation of the semi-finished cutting device according to the present invention configured as described above are as follows.
먼저, 반제품(1)을 나이프(4)쪽으로 공급하기 위해 후단컨베이어(3)를 구동시켜 후단컨베이어(3)로 반제품(1)을 전진시킨다. 그런 다음, 반제품(1)이 정해진 일정거리를 이동하게 되면 나이프(4)가 작동하여 반제품(1)을 일정 규격대로 자른다. 이 때, 온도조절장치(미도시)를 작동시키면 전선(미도시)을 통해 코일(8)로 열이 전달되면서 가열봉(7)이 가열된다. 가열봉(7)은 좌, 우측보다 가운데 부분에 코일(8)이 더 조밀하게 감겨져 있어 가열봉(7)의 온도편차가 줄어들어 가열봉(7)전체가 균일하게 가열된다. 이렇게 가이드판(5)에 삽입된 가열봉(7) 전체가 가열되면서 반제품(1)의 절단부위에 열이 균일하게 가해지게 된다.First, in order to supply the semifinished product 1 to the knife 4, the rear end conveyor 3 is driven to advance the semifinished product 1 to the rear end conveyor 3. Then, when the semi-finished product 1 moves a predetermined distance, the knife 4 is operated to cut the semi-finished product 1 to a certain standard. At this time, when the thermostat (not shown) is operated, the heating rod 7 is heated while heat is transferred to the coil 8 through an electric wire (not shown). In the heating rod 7, the coil 8 is more densely wound around the center than the left and right sides so that the temperature deviation of the heating rod 7 is reduced, so that the entire heating rod 7 is uniformly heated. Thus, as the whole heating rod 7 inserted into the guide plate 5 is heated, heat is uniformly applied to the cut portion of the semi-finished product 1.
절단된 타이어의 반제품(1)은 타이어 성형기의 성형드럼 쪽으로 보내진다. 운반된 반제품(1)은 성형드럼에 자동으로 감겨진 다음, 반제품(1)의 가열된 절단부위가 서로 접합된 상태에서 가압되어 타이어가 성형된다. 이렇게 접합부위가 가열된 상태에서 가압되므로 접합부위인 성형조인트의 접착력이 높아지게 된다.The semifinished product 1 of the cut tire is sent to the forming drum of the tire forming machine. The transported semifinished product 1 is automatically wound on a forming drum, and then pressurized while the heated cut portions of the semifinished product 1 are joined to each other to form a tire. Since the joint is pressed in the heated state, the adhesive force of the molding joint, which is the joint, is increased.
이상 설명한 바와 같이 본 발명의 반제품 절단장치에 의하면, 타이어의 반제품을 절단할 때에 반제품의 절단부위에 균일하게 열을 가함으로써 반제품의 절단부위간의 부착이 잘 이루어져서 그린 케이스 및 완제품 타이어상 성형조인트의 접착력이 강화되어 성형조인트가 벌어지거나 갈라지는 것을 방지할 수 있게 된다.According to the semi-finished cutting device of the present invention as described above, when cutting the semi-finished product of the tire, by applying heat evenly to the cut portion of the semi-finished product, the adhesion between the cut portions of the semi-finished product is well achieved, and thus the adhesion of the molded case on the green case and the finished tire This reinforcement prevents the molding joint from opening or cracking.
