Description

타이어 성형기의 자동조인트장치{Apparatus for Automatic Jointing Pre-Assy in a Tire Moulder}Apparatus for Automatic Jointing Pre-Assy in a Tire Moulder

본 고안은 타이어의 성형기에 관한 것으로, 더욱 자세하게는 2차성형에서 트레드 접착부(Joint Portion)에 자동 압착이 가능한 타이어 성형기의 자동조인트장치에 관한 것이다.The present invention relates to a molding machine of a tire, and more particularly, to an automatic joint device of a tire molding machine capable of automatic compression on a tread joint (Joint Portion) in the secondary molding.

타이어의 성형공정은, 전 공정인 압출, 재단 및 압연공정에서 사양에 따라 가공처리된 반제품을 운반하여 성형기에서 사양에 따라 조립하여 그린타이어(Green Tire)를 만들어 가류공정에 인계하는 중간공정이다. 이러한 타이어의 성형공정은, 인너라이너(Inner Liner), 카카스(Carcass), 비드(Bead), 사이드(Side) 등을 조립하여 1차그린타이어를 만드는 1차성형공정과, 상기 1차성형공정을 통해 제작된 그린타이어의 카카스층 위에 벨트(Belt), 트레드(Tread) 등을 조립하여 완제품 형상의 2차그린타이어를 만드는 2차성형공정으로 구분된다.The tire forming process is an intermediate process of carrying out the semi-finished product processed according to the specifications in the extrusion, cutting and rolling processes, which are assembled according to the specifications in the molding machine, to make a green tire, and taking over the vulcanization process. The tire molding process includes a primary molding process of assembling an inner liner, carcass, beads, and side to form a primary green tire, and the primary molding process. The belt is divided into a secondary molding process of assembling belts, treads, etc. on the carcass layer of the green tires to make secondary green tires in the shape of finished products.

상기 타이어의 2차성형공정 중 하나의 작업으로서, 예컨대 트레드의 압착작업은 성형기의 벨트드럼(Belt Drum)에 트레드를 감은 후(Wind-up), 트레드 절단면에 대하여 압착(Splicing)을 행하게 된다. 종래에는, 상기 트레드 압착작업은 자동화가 곤란하여 핸드롤러(Hand Roller) 등에 의해 수작업을 행하였다. 그러나, 이러한 종래의 압착작업은 작업자의 이동량이 많아지고, 작업능률의 저하를 초래할 뿐만아니라, 작업의 불균일성으로 한해 타이어의 품질저하를 초래하였다.As one of the operations of the secondary molding of the tire, for example, the crimping of the tread is performed after winding the tread on a belt drum of the molding machine (wind-up) and then pressing the tread on the cut surface of the tread. Conventionally, the tread pressing operation is difficult to automate, and thus manual work is performed by a hand roller or the like. However, this conventional crimping operation increases the amount of movement of the operator, not only decreases work efficiency, but also causes deterioration of tire quality due to uneven work.

따라서, 본 고안은 상기한 종래의 문제점을 해결하고자 안출된 것으로, 그 목적은 타이어의 2차성형공정에서 트레드 등 반제품의 절단면에 대한 압착작업을 생산규격 교체에 관계없이 반제품의 형상에 따라 항상 일치되도록 자동으로 할 수 있는 타이어 성형기의 조인트장치를 제공하는데 있다.Therefore, the present invention was devised to solve the above-described problems, and its purpose is to always match the pressing operation for the cutting surface of semi-finished products such as treads in the secondary molding process of tires according to the shape of semi-finished products regardless of production standard replacement. It is to provide a joint device of a tire molding machine that can be automatically as possible.

도 1은, 본 고안에 따른 자동조인트장치의 정면도이고, 도 2는, 그 측면도이다.1 is a front view of an automatic joint device according to the present invention, Figure 2 is a side view thereof.

본 고안에 따른 타이어 성형기의 자동조인트장치(10)는 2차성형기의 벨트드럼(5)의 상부에 위치한다. 상기 자동조인트장치(10)는 도 1 및 도 2에 도시된 바와 같이, 상기 벨트드럼(5)의 길이방향을 따라 설치된 멀티롤(4)과, 상기 멀티롤(4)을 벨트드럼(5)의 원주길이방향으로 따라 전후진시키는 제1실린더(1)와, 상기 멀티롤(4)을 상승 또는 하강시키는 제2실린더(2)와, 상기 멀티롤(4)을 가압하는 제3실린더(3)를 포함한다.The automatic joint device 10 of the tire molding machine according to the present invention is located above the belt drum 5 of the secondary molding machine. As shown in FIGS. 1 and 2, the automatic joint device 10 includes a multiroll 4 installed along a longitudinal direction of the belt drum 5, and the multiroll 4 with a belt drum 5. Of the first cylinder (1) for moving forward and backward along the circumferential length direction of the second cylinder, the second cylinder (2) for raising or lowering the multi-roll (4), and the third cylinder (3) for pressing the multi-roll (4). ).

상기 제1실린더(1)는, 결합부재(6)에 의해 상기 멀티롤(4)과 힌지결합(61)되어 있다. 따라서, 상기 제1실린더(1)의 로드(Rod)가 전진하면, 상기 결합부재(6)는 도 2의 실선으로 나타낸 것과 같이 아래로 이동하게 되고, 멀티롤(4)은 벨트드럼(5)의 원주를 따라 앞쪽(제3실린더 쪽)으로 전진하게 된다. 반대로, 상기 제1실린더(1)의 로드가 후진하면, 상기 결합부재(6)는 도 2의 가상선으로 나타낸것과 같이 위로 이동하게 되고, 멀티롤(4)은 벨트드럼(5)의 원주를 따라 뒤쪽(제1실린더 쪽)으로 전진하게 된다. 이러한 멀티롤(4)의 이동으로 인해 반제품의 접착부를 전부 가압할 수 있다.The first cylinder (1) is hinged (61) with the multi-roll (4) by a coupling member (6). Therefore, when the rod Rod of the first cylinder 1 is advanced, the coupling member 6 moves downward as shown by the solid line of FIG. 2, and the multi-roll 4 is the belt drum 5. Advance forward along the circumference of the cylinder (third cylinder side). On the contrary, when the rod of the first cylinder 1 reverses, the coupling member 6 moves upward as shown by the imaginary line in FIG. 2, and the multi-roll 4 moves the circumference of the belt drum 5. Therefore, it moves forward to the rear side (first cylinder side). Due to the movement of the multi-roll (4) it is possible to press all the adhesive portion of the semi-finished product.

상기 제2실린더(2)는, 상기 멀티롤(4)을 위 아래로 이동시키도록 함으로써 멀티롤(4)이 벨트드럼(5) 상에 밀착하거나 떨어지게 한다.The second cylinder 2 causes the multi-roll 4 to contact or fall on the belt drum 5 by moving the multi-roll 4 up and down.

또한, 상기 제3실린더(3)는, 로드 끝단에 가압부재(31, 32)가 마련되어 있어 상기 멀티롤(4)을 가압한다.In addition, the third cylinder 3 is provided with pressing members 31 and 32 at rod ends to press the multi-rolls 4.

도 3에, 상기 멀티롤의 상세한 구조가 도시되어 있다. 상기 멀티롤(4)은 도 3에 도시된 바와 같이, 다수개의 디스크(Disc, 42)로 구성되어 있으며, 상기 각 디스크(42)는 원주방향을 따라 다수개의 볼(43)이 삽입되어 있다. 또한, 상기 디스크(42)는, 중심에 관통구(44)와 표면에 홈(45, 46)이 형성되어 있어, 상기 관통구(44)에 제1축(41)에 삽입되는 한편, 여러 개의 디스크들이 맞물려 조립될 수 있다. 이렇게 다수개의 디스크(42)로 구성되는 멀티롤(4)은, 반제품을 압착하여 조인트할 때, 반제품의 표면이 굴곡진 경우에도 균일한 압착을 가능하게 한다.In Fig. 3, the detailed structure of the multiroll is shown. As shown in FIG. 3, the multi-roll 4 is composed of a plurality of discs Disc 42, each of which has a plurality of balls 43 inserted along the circumferential direction. In addition, the disc 42 has a through hole 44 at its center and grooves 45 and 46 formed at its surface, and is inserted into the first shaft 41 in the through hole 44. The disks can be meshed and assembled. In this way, the multi-roll 4 composed of a plurality of disks 42 enables uniform pressing even when the surface of the semi-finished product is curved when the semi-finished product is pressed and jointed.

한편, 상기 멀티롤(4)의 위쪽에, 가압롤(71, 72)이 장착된 제2축(7)이 설치되어 있는 것이 바람직하다. 상기 제2축의 가압롤(71, 72)들은 반제품의 폭에 따라 수동으로 임의로 그 폭을 조정하여 상기 멀티롤(4)에 가해지는 압력을 균일하게 해준다.On the other hand, it is preferable that the 2nd axis | shaft 7 with which the pressure rolls 71 and 72 are attached to the upper part of the said multi roll 4 is provided. The pressure rolls 71 and 72 of the second shaft manually adjust their widths manually according to the width of the semi-finished product to make the pressure applied to the multi-roll 4 uniform.

이하, 본 고안에 따른 자동조인트장치에 대한 작용효과를 상세히 설명한다.Hereinafter, the effect of the automatic joint device according to the present invention will be described in detail.

도 4는, 본 고안의 자동조인트장치의 작동상태를 보이고 있다. 도 4에 도시된 바와 같이, 본 고안에 따른 자동조인트장치를 이용하여, 예컨대 트레드(9)를 조인트하는 경우, 먼저 벨트드럼(5)에 벨트(8)를 감은 후 트레드(9)를 감는다. 이때, 상기 자동조인트장치의 제1실린더(1)는 전진하여 결합부재(6)를 밀고, 이에 따라 멀티롤(4)은 벨트드럼(5)의 앞쪽으로 전진하게 된다. 그 후, 제2실린더(2)의 로드가 전진하면서 상기 멀트롤(4)의 디스크(42)를 하강시켜 벨트드럼(5)의 표면 위의 트레드(9) 접착부를 누른다. 이러한 상태에서 제3실린더(3)에 의해 상기 멀티롤(4)은 일정한 압력으로 가압되어 트레드 접착부를 가압하여 접합시킨다.Figure 4 shows the operating state of the automatic joint device of the present invention. As shown in FIG. 4, for example, when the tread 9 is jointed using the automatic joint device according to the present invention, the belt 8 is first wound on the belt drum 5, and then the tread 9 is wound. At this time, the first cylinder 1 of the automatic joint device is advanced to push the coupling member 6, and thus the multi-roll 4 is advanced to the front of the belt drum (5). Thereafter, as the rod of the second cylinder 2 moves forward, the disk 42 of the mullet 4 is lowered to press the tread 9 bonding portion on the surface of the belt drum 5. In this state, the multi-roll 4 is pressurized by a constant pressure by the third cylinder 3 to press and bond the tread adhesive part.

트레드 접착이 완료된 후에는 반대로, 제3실린더(3)는 후진하여 상승하며, 제2실린더(2)는 멀티롤(4)을 상승시킨 후 제1실린더(1)는 후진하여 멀티롤을 뒤쪽에 원위치시킨다.On the contrary, after the tread adhesion is completed, the third cylinder 3 reverses and ascends, the second cylinder 2 raises the multi-roll 4, and then the first cylinder 1 retreats to back the multi-roll. Replace it.

이러한 일련의 동작을 통해 벨트층에 감긴 트레드는, 그 접착부의 면 형상에 따라 다수개의 디스크로 형성된 멀티롤에 의해 균일한 힘으로 압착작업이 이루어지게 된다.Through this series of operations, the tread wound on the belt layer is pressed by a uniform force by a multi-roll formed of a plurality of disks according to the surface shape of the adhesive portion.

상술한 바와 같이, 본 고안에 따른 자동조인트장치에 의하면, 타이어의 2차성형공정에서 트레드 등 반제품의 절단면에 대한 압착작업을 생산규격 교체에 관계없이 자동으로 할 수 있을 뿐만 아니라, 반제품의 형상에 따라 항상 균일한 압력으로 가압되도록 함으로써, 완제품의 품질을 균일하게 할 수 있는 매우 유용한 효과가 있다.As described above, according to the automatic joint device according to the present invention, not only can the crimping work on the cutting surface of the semi-finished product such as the tread in the secondary molding process of the tire be performed regardless of the production standard replacement, Therefore, by being always pressurized to a uniform pressure, there is a very useful effect that can make the quality of the finished product uniform.
