Description
본 고안은 타이어 2차 성형용 트랜스퍼 링 장치에 관한 것으로서, 특히 트랜스퍼되는 PCR 타이어의 2차 성형용 반제품에 걸리는 하중을 적절히 분산함으로써 타이어 트레드 연결부의 분리를 방지할 수 있는 타이어 2차 성형용 트랜스퍼 링 장치에 관한 것이다.The present invention relates to a transfer ring device for secondary tire forming, and in particular, a secondary ring for tire secondary forming, which can prevent the separation of the tire tread connection by appropriately distributing the load on the semi-finished product for secondary forming of the transferred PCR tire. Relates to a device.
도 1에, 트랜스퍼 링 장치를 포함하는 통상적인 그린타이어의 2차 성형기가 도시되어 있다. 먼저, 벨트(7)와 트레드(6)가 벨트 드럼(belt drum)(4)에 차례로 감기면, 트랜스퍼 링 장치(101)가 벨트(7)와 트레드(6)의 조립체를 플랜지(flange)(5)에 전달시키게 된다. 플랜지(5)에는 이미 인너라이너, 카카스플라이, 비드, 사이드월 등이 조립된 1차 그린타이어가 삽입되어 있으므로, 최종적으로 1차 그린타이어 위에 벨트와 트레드가 결합되는 상태가 되는 것이다.In Fig. 1, a secondary green forming machine of a conventional green tire including a transfer ring device is shown. First, when the belt 7 and the tread 6 are wound on the belt drum 4 in turn, the transfer ring device 101 flanges the assembly of the belt 7 and the tread 6 into a flange ( 5). Since the primary green tire having the inner liner, carcass ply, bead, sidewall, etc. already assembled is inserted into the flange 5, the belt and the tread are finally joined to the primary green tire.
이 때, 상기 트랜스퍼 링 장치(101)는, 도 2에서와 같이, 상부 플랜지(11)와 접촉 플랜지(12)로 구성되어 있으며, 상기 접촉 플랜지(12)에는 복수의 결합 핀(20)(30)이 끼워져 있다.At this time, the transfer ring device 101 is composed of an upper flange 11 and a contact flange 12, as shown in Figure 2, the contact flange 12, a plurality of coupling pins 20 (30). ) Is inserted.
실제 트랜스퍼가 이루어질 경우, 상기 접촉 플랜지(12)가 상기 반제품의 트레드 부위에 접촉하면, 결합 핀(20)(30)이 반제품에 압착되어 옮길 수 있게 되어 있다. 이는, 상기 접촉 플랜지(12) 면에 설치된 다수의 결합 핀(20)(30)에 의해이루어지게 된다. 도 3에서와 같이, 상기 결합 핀(20)(30)은 단부가 뾰족하게 되어 있어, 상기 반제품의 트레드 부위에 압착되면 빠지지 않고 트랜스퍼가 이루어지게 된다. 특히, 상기 접촉 플랜지(12)에는 트레드의 연결부(joint)가 접촉 및 압착되게 되어 있다.When the actual transfer is made, when the contact flange 12 contacts the tread portion of the semifinished product, the coupling pins 20 and 30 are pressed against the semifinished product so that they can be moved. This is accomplished by a plurality of coupling pins 20, 30 installed on the contact flange 12 face. As shown in FIG. 3, the coupling pins 20 and 30 have sharpened ends, so that the coupling pins 20 and 30 do not fall out when they are pressed against the tread portion of the semi-finished product. In particular, the contact flange 12 has a joint of a tread contacted and pressed.
종래에는, 상기 결합 핀(20)(30)의 배열이 중앙에 2개, 및 양 숄더부위에 2개씩 설치되어 있었기 때문에, 파지력이 낮아서 트랜스퍼시 반제품의 자중 및 관성으로 인해 빠지기 쉬웠고, 결합 핀(20)(30)이 위치한 트레드 연결부의 몇 부분에 응력이 집중되기 때문에, 트레드 연결부가 종종 분리되는 문제점이 있었다.In the related art, since the arrangement of the coupling pins 20 and 30 was provided at two in the center and two at both shoulders, the holding force was low, so it was easy to fall off due to the weight and inertia of the semi-finished product during transfer. Since stress is concentrated in some portions of the tread connection where 20) (30) is located, the tread connection has often been a problem.
본 고안은 상기한 문제점을 해결하기 위해 안출된 것으로서, 고안의 목적은 트레드에 대한 파지력을 높이고 트레드 연결부에 작용되는 하중을 분산시켜서 트랜스퍼시 타이어의 품질에 미치는 악영향을 제거하는데 있다.The present invention has been made to solve the above problems, the object of the invention is to increase the gripping force on the tread and to distribute the load applied to the tread connection to remove the adverse effect on the quality of the transfer tire.

상기한 목적을 달성하기 위해, 본 고안에 따른 타이어 2차 성형용 트랜스퍼 링 장치는,In order to achieve the above object, the transfer ring device for tire secondary molding according to the present invention,
상부 플랜지와 접촉 플랜지로 구성되어 있고,Consisting of an upper flange and a contact flange,
상기 접촉 플랜지의 중앙부위에는 결합 핀이 2∼4개 배치되어 있으며,2 to 4 coupling pins are disposed at the central portion of the contact flange,
상기 접촉 플랜지의 양 숄더부위에는 결합 핀이 2열씩 배치되어 있고, 상기 2열의 결합 핀은 타이어 원주방향을 따라 지그재그 형식으로 배치된 것을 특징으로 한다.Coupling pins are arranged in two rows at both shoulder portions of the contact flange, and the two coupling pins are arranged in a zigzag form along the tire circumferential direction.
여기서, 상기 한쪽 숄더부위에 배치된 2열의 결합 핀 수는 13∼15개인 것이 바람직하다.Here, it is preferable that the number of coupling pins of two rows arrange | positioned at the said one shoulder part is 13-15.
이하, 첨부도면을 참조하여 본 고안의 일 실시예를 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described an embodiment of the present invention;
본 고안에 따른 타이어 2차 성형용 트랜스퍼 링 장치가 상부 플랜지(11)와 접촉 플랜지(12)로 구성된 것은 종래와 동일하다.The transfer ring device for tire secondary molding according to the present invention is composed of the upper flange 11 and the contact flange 12 as in the prior art.
그리고, 상기 접촉 플랜지(12)의 중앙부위에는 2개의 결합 핀(20)이 배치되어 있다. 타이어 반제품의 이탈을 막기 위해 중앙의 결합핀(30)은 2개 이상 필요하지만 4개를 초과할 필요는 없다.In addition, two coupling pins 20 are disposed at the central portion of the contact flange 12. In order to prevent the separation of semi-finished products, two or more central coupling pins 30 are required, but not more than four.
또한, 상기 접촉 플랜지(12)의 양 숄더부위에는 결합 핀(20)이 2열씩 배치되어 있으며, 상기 2열은 타이어 원주방향을 따라 지그재그 형식으로 배치되어 있다. 결합 핀(20)이 지그재그 형식으로 배치되어 있기 때문에, 타이어 반제품에 대한 파지력은 한층 증가될 수 있다.In addition, two rows of coupling pins 20 are arranged at both shoulder portions of the contact flange 12, and the two rows are arranged in a zigzag form along the tire circumferential direction. Since the engaging pins 20 are arranged in a zigzag fashion, the gripping force on the tire semifinished product can be further increased.
더욱이, 상기 한쪽 숄더부위에 배치된 2열의 결합 핀(20)의 수를 13∼15개로 함으로써, 파지력 및 하중의 분산 효과를 도모하였다. 특히, 상기 접촉 플랜지(12)에는 트레드 연결부가 접촉하게 되므로, 하중을 적절히 분산시켜서 연결부가 상호 분리되는 경우가 없도록 하는 것이 중요하다. 그러나, 15개를 넘으면 더 이상 효과의 향상은 볼 수는 없었다.Moreover, the holding force and the dispersion | distribution effect of a load were aimed at by setting the number of the coupling pins 20 of two rows arrange | positioned at the said one shoulder part to 13-15 pieces. In particular, since the tread connection part comes into contact with the contact flange 12, it is important to properly distribute the load so that the connection part does not separate from each other. However, beyond 15, no improvement in effect was seen.
한편, 상기 2열의 결합핀(20)이 13∼15개 배치됨에 따라서 접촉 플랜지(12)도 종래보다는 타이어 원주방향으로 길어지게 된다. 예컨대, 종래보다 약 2배 이상 커지게 된다.On the other hand, as the two rows of coupling pins 20 are arranged 13 to 15, the contact flange 12 is also longer in the circumferential direction of the tire than in the prior art. For example, it is about 2 times larger than the conventional one.
상기한 바와 같은 구성의 본 고안에 따르면, 타이어 원주방향을 따라 다수의 결합 핀을 지그재그 형식으로 배치함으로써, 타이어 반제품(트레드 연결부)에 대한 파지력이 높아지고 하중이 적절히 분산되므로, 최종 타이어의 품질이 크게 향상된다는 이점이 있다.According to the present invention of the configuration as described above, by arranging a plurality of coupling pins in a zigzag form along the tire circumferential direction, the grip on the semi-finished product (tread connection) is increased and the load is properly distributed, so that the quality of the final tire is greatly There is an advantage of being improved.
