Description

타이어용 스티쳐의 구조{A Structure of Stitcher for Tire}Structure of Stitcher for Tire

본 발명은 타이어 제조시 사용되는 스티쳐(Stitcher)에 관한 것으로, 특히 연성우레탄과 치차형롤이 조합된 회전롤러가 구비된 스티쳐를 통해서 스티칭하는 재료의 외형에 따라 치차형롤의 외형(높낮이)이 변화되어 재료의 공기입 불량을 방지하는 한편, 재료와의 접촉면적을 감소시켜 밴드드럼으로부터 재료가 미끄러지는 현상도 방지할 수 있도록 된 타이어용 스티쳐의 구조에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stitcher used in the manufacture of tires, and in particular, the outer shape (height) of the toothed roll is changed depending on the shape of the material stitched through the stitcher having a rotary roller in which a soft urethane and a toothed roll are combined. The present invention relates to a structure of a stitcher for a tire that is changed to prevent a bad air intake of the material and to prevent the sliding of the material from the band drum by reducing the contact area with the material.

일반적으로, 타이어 제조 공정 중에는 인너라이너(Inner Liner)와 사이드월(Sidewall) 등과 같은 타이어 구성재료를 밴드드럼 상에서 접합시키는 스티칭(Stitching) 공정이 있는데, 이러한 스티칭 작업에 사용되는 밴드드럼과 밴드공급기 및 스티쳐의 구성에 대해 살펴보면, 도 8에서 보는 바와 같이, 재료가 권취되는 밴드드럼(101)에 인접되어 밴드공급기(102)가 위치되고, 이 밴드공급기(102)의 하부에 지지플레이트(103)가 부착되며, 이 지지플레이트(103)에 제1실린더(103a)가 설치되는 한편, 이 제1실린더(103a)의 로드(103b)와 브래킷(104)의 일단과 연결되고, 이 브래킷(104)의 다른 일단과 연결되고 리니어모션가이드(Linear Motion Guide;105)를 통해 상기 지지플레이트(103)의 하부를 따라 직선 운동하도록 된 이동플레이트(106)가 구비되며, 이 이동플레이트(106)의 끝단에 원통형롤러(107)가 설치되며, 상기 이동플레이트(106)의 하부에 연결된 연결부재(108)를 매개로 제2실린더(109)의 로드(109a)에 스폰지롤러(110)가 설치되는 구조로 이루어진다.In general, a tire manufacturing process includes a stitching process in which tire components such as an inner liner and a sidewall are bonded onto a band drum, and a band drum and a band feeder used for such stitching operations. Looking at the configuration of the stitcher, as shown in Figure 8, the band feeder 102 is located adjacent to the band drum 101, the material is wound, the support plate 103 in the lower portion of the band feeder 102 The first cylinder 103a is attached to this support plate 103, and is connected to the rod 103b of this first cylinder 103a and one end of the bracket 104, and this bracket 104 is attached. A moving plate 106 connected to the other end of the linear motion guide 105 and linearly moving along the lower portion of the support plate 103 through a linear motion guide 105 is provided at the end of the moving plate 106. Cylindrical Errors (107) are installed, made of a parameter the lower connecting member 108 connected to the moving plate 106 to the rod (109a) structure that is a sponge roller (110) installed in the second cylinder (109).

이에 따라, 상기 밴드공급기(102)에서 공급되는 재료가 밴드드럼(101)에 권취되는 동안 상기 제1실린더(103a)의 로드(103b)가 확장됨에 따라 상기 리니어모션가이드(105)가 밴드드럼(101) 쪽으로 이동되면서 상기 원통형롤러(107)에 의해 1차적으로 압착된 후, 상기 스폰지롤러(110)에 의해 재차 압착된다.Accordingly, as the rod 103b of the first cylinder 103a is extended while the material supplied from the band feeder 102 is wound on the band drum 101, the linear motion guide 105 may be a band drum ( After being primarily pressed by the cylindrical roller 107 while being moved toward 101, it is pressed again by the sponge roller 110.

그러나, 공급되는 재료가 균일한 두께로 이루어지지 않고 단차가 있을 경우에는 상기 스폰지롤러(110)를 통해 추가적인 스티칭 작업을 시행하여도 압착이 완전하게 이루어지지 못하고 재료들 사이에 공기가 들어가는 불량이 발생하는 문제점이 있었다.However, if the material to be supplied is not made of a uniform thickness and there is a step, even if additional stitching is performed through the sponge roller 110, the crimping is not completed completely, and a defect of air entering between the materials occurs. There was a problem.

또한, 상기 밴드드럼(101)의 표면은 차후 압착/권취된 재료(밴드케이스)와의 분리 용이성을 위해 코팅 처리되어 있기 때문에, 도 9에서 보는 바와 같이, 제1재료와 제2재료가 압착된 1차 성형품인 밴드케이스(111)에 가해지는 원통형롤러(107)의 압착력이 조금만 증가되어도 밴드케이스(111)가 상기 밴드드럼(101)으로부터 이탈(A 부분)되어 구겨지는 문제점도 있었다.In addition, since the surface of the band drum 101 is coated for ease of separation from the subsequent crimped / wound material (band case), as shown in FIG. 9, the first material and the second material are compressed. Even if the pressing force of the cylindrical roller 107 applied to the band case 111, which is a vehicle molded product, is slightly increased, the band case 111 is detached from the band drum 101 (part A) and wrinkled.

이에 본 발명은 상기와 같은 문제점을 해결하기 위해 발명된 것으로, 연성우레탄과 치차형롤이 조합된 회전롤러를 통해 권취되는 재료 또는 재료들간의 단차에 따라 상기 치차형롤의 외형(높낮이)이 함께 변화되면서 재료를 압착하도록 되어, 권취되는 재료의 공기입 불량을 방지하고 밴드케이스가 밴드드럼 표면에서 미끄러지는 현상을 억제하여 밴드케이스의 구겨짐도 방지할 수 있도록 된 타이어용 스티쳐의 구조를 제공하는데 그 목적이 있다.Accordingly, the present invention has been invented to solve the above problems, while the outer shape (height) of the toothed roll is changed together according to the step of the material or materials wound through the rotating roller combined with a flexible urethane and toothed roll. It is to provide a structure of a tire stitcher that is capable of compressing the material so as to prevent a poor air intake of the wound material and to prevent the band case from slipping on the surface of the band drum, thereby preventing the band case from being wrinkled. There is this.

On the other hand, the upper end of the bracket (9) is connected to the end of the rod (6a) of the cylinder (6). Further, the lower portion of the bracket (9) is provided with a movable plate (7), the linear motion guide (8) The movable plate 7 is installed to linearly move along the lower portion of the support plate 5 through the medium, and the guide shaft 13 is installed at the lower portion of the movable plate 7, and the guide shaft 13 is provided. The linear motion guide 11 is moved to the left and right along the guide shaft 13, and the rotary shaft 15 is installed below the guide shaft 13 in parallel with the guide shaft 13. The rotating roller 10 connected to the guide 11 is rotatably provided on the rotating shaft 15 with the bearing 14 interposed therebetween, while the rotating roller 10 is disposed below the moving plate 7. It is installed to receive the rotational driving force through the drive motor 12 and the belt is installed.

여기서, 상기 회전롤러(10)의 외주면에는 탄성을 지닌 연성우레탄(10d)이 설치되고, 이 연성우레탄(10d)의 외주면에는 각각 홈의 크기가 순차적으로 작아지게 형성된 제1치차형롤(10a), 제2치차형롤(10b), 제3치차형롤(10c)이 설치되어 있다.Here, a flexible urethane (10d) having elasticity is installed on the outer circumferential surface of the rotary roller (10), the first gear-shaped roll (10a), each of which is formed in the outer circumferential surface of the flexible urethane (10d) so that the size of the grooves sequentially smaller; The second geared roll 10b and the third geared roll 10c are provided.

이에 따라, 상기 밴드공급기(2)에서 공급되는 재료가 밴드드럼(1)상에 권취되는 동안 상기 실린더(6)의 로드(6a)가 확장되어 이동플레이트(7)가 리니어모션가이드(8)에 의해 직선운동되면서 상기 회전롤러(10)가 밴드드럼(1)에 근접된다. 이후 상기 회전롤러(10)의 치차형롤(10a,10b,10c)들이 밴드드럼(1)에 권취되는 재료에 압착력을 가하게 된다. 이때, 큰 치형을 갖는 제1 치차형롤(10a)이 우선적으로 밴드케이스(16)를 누르게 되어 밴드케이스(16)가 밴드드럼(1)에 대하여 미끄러지지 않게 하고, 차츰 작은 치형을 갖는 제2 치차형롤(10b) 및 제3 치차형롤(10c)이 순차적으로 밴드케이스(16)를 스티칭하게 된다.Accordingly, the rod 6a of the cylinder 6 is extended while the material supplied from the band feeder 2 is wound on the band drum 1 so that the movable plate 7 is moved to the linear motion guide 8.

At this time, the first toothed roll 10a having a large tooth presses the band case 16 preferentially so that the band case 16 does not slip against the band drum 1, and the second toothed roll having a smaller tooth is gradually formed. 10b and the third gear roll 10c sequentially stitch the band case 16.

한편, 재료의 폭에 따라서 상기 회전롤러(10)들은 도 10a 및 도 10b에 도시한 바와 같이, 안내축(13)을 따라 좌/우 이동되는 리니어모션가이드(11)를 매개로 간격이 조정되어 재료에 전체적으로 압착력을 가할 수 있게 된다.On the other hand, according to the width of the material as shown in Figure 10a and 10b, the rotating rollers 10, the interval is adjusted via the linear motion guide 11 which is moved left and right along the guide shaft 13 Compressive forces can be applied to the material as a whole.

이때, 상기 회전롤러(10)는 재료의 단차가 있을 경우, 각각 분리/설치된 제1,2,3치차형롤(10a,10b,10c)들이 연성우레탄(10d)쪽으로 재료의 단차만큼 밀려들어가도록 되어, 재료의 단차에 따라 치차형롤(10a,10b,10c)들의 형상(높낮이)이 변화되어 각각 균일한 압착력을 가하게 된다.즉, 도 10a에 도시한 바와 같이, 재료의 단차가 발생되기 전 상태에서는 제1,2,3치차형롤(10a,10b,10c)의 높낮이의 변화가 발생되지 않지만, 리니어모션가이드(11)에 의해 간격이 조정되는 상태에서 재료의 단차가 발생되면, 도 10b에 도시한 바와 같이, 제1치차형롤(10a)이 재료의 단차에 의해 연성우레탄(10d)쪽으로 가장 많이 밀려들어가게 되고, 그 다음에 제2치차형롤(10b)이 연성우레탄(10d)쪽으로 밀려들어가게 되며, 마지막으로 재료의 단차에 의해 제3치차형롤(10c)이 가장 적은 양만큼 연성우레탄(10d)쪽으로 밀려들어가게 됨으로써 제1,2,3치차형롤(10a,10b,10c) 사이에서 높낮이의 변화가 발생되는 것이다.이와 같이 제1,2,3치차형롤(10a,10b,10c)의 내측에 구비된 연성우레탄(10d)이 눌려지면서 밴드케이스(16)의 단차나 곡선행태에 따라 스티칭이 실시된다.At this time, the rotary roller 10, if there is a step of the material, the first, second and third geared rolls (10a, 10b, 10c) separated / installed respectively are pushed by the step of the material toward the flexible urethane (10d) The shape (height) of the toothed rolls 10a, 10b, and 10c is changed according to the step of the material, thereby applying a uniform pressing force, respectively. That is, as shown in Fig. 10a, in the state before the step of the material is generated, If the height of the first, second, and third geared rolls 10a, 10b, and 10c does not change, but if a step is generated in the state where the gap is adjusted by the linear motion guide 11, it is shown in Fig. 10B. As shown, the first gear roll 10a is pushed most toward the flexible urethane 10d by the step of the material, and then the second gear roll 10b is pushed toward the flexible urethane 10d. As a result of the step difference in material, the third gear roll 10c has the least amount of soft rain. As it is pushed toward the letan 10d, a change in height occurs between the first, second and third toothed rolls 10a, 10b and 10c. As such, the first, second and third toothed rolls 10a, 10b and 10c are generated. While the flexible urethane (10d) provided on the inside of the pressing is pressed according to the step or curve behavior of the band case (16).

한편, 상기 회전롤러(10)는, 도 7에서 보는 바와 같이, 치차형롤(10a,10b,10c)들이 밴드케이스(16)와 접촉되는 면적(40%)보다 비접촉되는 면적(60%)이 더 크기 때문에 밴드드럼(1)과 밴드케이스(16)사이에 일어나는 미끄러짐(밴드케이스 구겨짐)현상을 억제할 수 있게 된다.On the other hand, the rotary roller 10, as shown in Figure 7, the toothed roll (10a, 10b, 10c) the contact area (60%) more than the area (40%) that is in contact with the band case 16 more (60%) Due to the size, the phenomenon of slipping (band case wrinkling) occurring between the band drum 1 and the band case 16 can be suppressed.

이상 설명한 바와 같이 본 발명에 따르면, 회전롤러의 외주면에 연성우레탄이 설치되고, 이 연성우레탄상에 치차형롤들이 다수개 분리/설치되어, 공급되는 재료의 단차에 따라 상기 치차형롤들의 외형이 변화되면서 재료의 단차를 흡수하게 되어 재료의 공기입 불량을 방지하는 한편, 재료와 접촉되는 치차형롤의 면적이 축소됨에 따라 밴드케이스가 밴드드럼으로부터 분리되어 벗겨지는 현상도 방지할 수 있는 효과가 있다.As described above, according to the present invention, a flexible urethane is installed on the outer circumferential surface of the rotary roller, and a plurality of toothed rolls are separated / installed on the flexible urethane, so that the shape of the toothed rolls changes according to the step of the supplied material. By absorbing the step difference of the material to prevent the poor air intake of the material, as the area of the toothed roll in contact with the material is reduced, there is an effect that can prevent the phenomenon that the band case is separated from the band drum and peeled off.
