Description

일렬비드의 구조 변형 방지를 위한 실 랩핑장치{Tread wrapping apparatus for transformation prevention of line beads}Thread wrapping apparatus for transformation prevention of line beads

본 발명은 타이어의 구성 요소 중 비드의 변형방지를 위해 감싸는 비드 랩핑(Bead wrapping) 장치에 관한 것으로, 특히 실을 이용하여 일렬 다층으로 배치되는 토핑된 와이어들로 이루어진 비드를 감싸아 이 비드의 안정성 확보와 가류 후 변형방지가 구현되는 일렬비드의 구조변형 방지를 위한 실 랩핑장치에 관한 것이다.The present invention relates to a bead wrapping device for wrapping the bead of the tire components to prevent the deformation of the bead, in particular the stability of the bead by wrapping a bead consisting of topping wires arranged in a line multilayer using a thread The present invention relates to a seal wrapping apparatus for preventing deformation of a single row bead in which deformation and securing after cure are implemented.

공지된 바와 같이 타이어의 구성 요소 중 비드는 타이어와 림의 체결력을 지탱하고, 타이어 내부의 공기압을 유지 밀폐시키며, 주행시 사이드부의 쿠션과 조정안정성의 중요한 역할을 수행하는 역할을 하게 된다.As is known, the beads of the tire components support the fastening force between the tire and the rim, maintain and seal the air pressure inside the tire, and play an important role in cushioning and adjusting stability of the side part during driving.

한편, 이러한 비드의 구성은 나비드와 필러로 구성되어 있으며, 이 나비드는 여러 종류가 있는데 가장 많이 사용하는 것이 다열 사각비드와 일렬 육각비드이다.On the other hand, the bead is composed of a butterfly and a filler, there are several kinds of this butterfly is the most commonly used multi-row square beads and single row hexagon beads.

여기서 다열 사각비드는 와이어를 대략 4∼5개씩 정렬하여 고무로 토핑한 후 냉각하여 포머에서 4∼5층으로 권취하며 여러 가닥의 와이어가 고무로 연결되어 있어서 와이어의 풀림이 발생하지 않도록 되어 있다.Here, the multi-row square beads are lined up with about 4 to 5 wires, topping with rubber, then cooled and wound into 4 to 5 layers in a former. The wires of several strands are connected with rubber to prevent loosening of the wires.

그러나 후자인 일렬 육각비드의 경우 하나의 와이어를 고무로 토핑한 후 냉각하여 포머에서 한 줄씩 횡으로 권취한 다음 2 단으로 이동하여 다시 횡으로 권취하는 방식으로 만들어지는데, 이때 하나의 와이어를 연속 사용함으로 권취후 이 와이어의 시작 부분이나 끝부분에서 와이어의 들뜸 현상이 발생하게 되기 때문에 이를 방지하기 위해 비드를 코드지로 감싸거나 끝부분을 고무로 감싸는 랩핑(Wrapping) 작업이 있었다(도 3참조).However, in the latter case, a single row hexagon bead is made by topping one wire with rubber, cooling it, winding it side by side in a former, and then moving it to the second stage and winding it laterally. As a result, the wires were lifted at the beginning or the end of the wire after winding, so that there was a wrapping operation to wrap the beads with cord paper or wrap the ends with rubber (see FIG. 3).

따라서 종래에는 일렬 육각비드를 제조할 때 와이어의 시작부분과 끝부분의 안정성 확보하기 위해 주로 얇은 고무 내지는 코드지를 감싸는 구조를 취했으며, 물론 이러한 종래 방식들은 타이어의 품도에 영향을 끼치지 않으나 수작업으로 생산성이 떨어져 대량 생산에는 적합하지 않았다.Therefore, conventionally, when manufacturing single row hexagon beads, a structure of wrapping thin rubber or cord paper was mainly used to secure the stability of the beginning and the end of the wire. Of course, these conventional methods do not affect the quality of the tire, As a result, productivity was not suitable for mass production.

이에 본 발명은 상기와 같은 종래 문제점을 해결하기 위해 발명된 것으로, 실을 이용하여 자동으로 비드의 시작 부분과 끝부분을 감싸아 비드의 안정성 확보와 가류후 변형방지 및 타이어 품도 개선이 이루어지는 일렬비드의 구조변형 방지를 위한 실 랩핑장치를 제공함에 그 목적이 있다.Therefore, the present invention was invented to solve the above-mentioned conventional problems, and automatically wraps the start and end portions of the beads using a seal to secure the stability of the beads, prevent deformation after vulcanization, and improve tire quality. It is an object of the present invention to provide a seal wrapping device for preventing structural deformation of beads.

상기와 같은 목적을 달성하기 위한 본 발명은 기대에 설치되어 에어 실린더에 의해 전, 후진 되는 고정판, 이 고정판에 설치되는 안내롤들, 상기 고정판의 링크를 매개로 연결되어 에어 실린더에 의해 회동하는 압착롤, 이 압착롤에 대응되어 나비드를 모터의 회전축에 의해 회전시키는 구동롤, 상기 구동롤과 압착롤 및 안내를 사이에 위치한 나비드의 처음부분과 끝부분을 재봉하는 니들을 갖춘 미싱부 및, 상기 니들의 실을 절단하도록 에어 실린더에 의해 작동하는 히터 커팅부로 이루어져 있다.The present invention for achieving the above object is installed on the base to be forward, backward by the air cylinder fixed guide, guide rolls installed on the fixed plate, connected via the link of the fixed plate is rotated by the air cylinder Rolls, drive rolls corresponding to the pressing rolls for rotating the butterfly by the rotational shaft of the motor, sewing machines having needles for sewing the first and end portions of the butterfly positioned between the driving roll, the pressing roll and the guide; And a heater cutting part operated by an air cylinder to cut the thread of the needle.

이하, 본 발명을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 따른 일렬비드의 구조변형 방지를 위한 실 랩핑장치의 전체 사시도 이고, 도 2는 본 발명의 요부인 구동부의 사시도 이다.1 is an overall perspective view of a seal wrapping device for preventing structural deformation of a single row bead according to the present invention, Figure 2 is a perspective view of a drive unit which is a main part of the present invention.

본 발명은 기대(1)에 설치되어 에어실린더(2)에 의해 전, 후진 되는 고정판(3), 이 고정판(3)에 설치되어 나비드(4)를 안내하는 여러 개의 안내롤(5), 상기 고정판(3)의 링크(6)를 매개로 연결되어 다른 에어실린더(7)에 의해 부분 회동하는 압착롤(8), 이 압착롤(8)에 대응되어 나비드(4)를 모터(9)의 회전축(10) 구동에 의해 회전시키는 구동롤(11), 상기 구동롤(11)과 압착롤(8)및 안내롤(5) 사이에 위치한 나비드(4)의 처음부분과 끝부분을 재봉하는 니들(12)을 갖춘 미싱부(13) 및 상기 니들(12)의 실(14)을 절단하도록 에어실린더(15)에 의해 작동하는 히터 커팅부(16)로 이루어져 있다.The present invention provides a fixed plate (3) installed on the base (1) to be moved forward and backward by the air cylinder (2), a plurality of guide rolls (5) installed on the fixed plate (3) to guide the butterfly (4), A press roll 8 connected through a link 6 of the fixing plate 3 to be partially rotated by another air cylinder 7, corresponding to the press roll 8, moves the butterfly 4 to the motor 9. The first and end portions of the butterfly 4, which is located between the driving roll 11, the driving roll 11 and the pressing roll 8 and the guide roll 5 to rotate by driving the rotary shaft 10 of It consists of a sewing unit 13 having a needle 12 to sew and a heater cutting unit 16 operated by the air cylinder 15 to cut the thread 14 of the needle 12.

이와 같이 이루어진 본 발명의 작용을 설명한다.The operation of the present invention made as described above will be described.

공지의 비드 와인더에서 권취한 나비드(4)를 와이어 선단(17)이 도 2의 위치에 오도록 방향을 잡고 구동롤(11)과 안내롤(5) 위에 올려놓는다.The butterfly 4 wound in a known bead winder is oriented so that the wire tip 17 is in the position shown in FIG. 2 and placed on the drive roll 11 and the guide roll 5.

이때 감지센서(18)가 나비드(4)의 장착위치를 감지하게 되면, 에어실린더(7)가 전진하여 링크(6)에 연결된 압착롤(8)을 힌지축(19)을 지점으로 회동시키어 상기 나비드(4)를 구동롤(11)과 압착롤(8) 사이에 밀착시킨다.At this time, when the sensor 18 detects the mounting position of the butterfly 4, the air cylinder (7) is advanced to rotate the hinge shaft (19) to the point of the pressing roll (8) connected to the link (6) The butterfly 4 is in close contact between the driving roll 11 and the pressing roll (8).

이렇게 상기 나비드(4)를 밀착 시킨 후 에어실린더(2)의 수축으로 고정판(3)은 후진하게 되는바, 이 고정판(3)이 후진하게 되면 나비드(4)를 미싱부(13)의 실(14)로 감싸는 랩핑 작업위치까지 이동한다.In this manner, after the butterfly 4 is in close contact with the air cylinder 2, the fixed plate 3 is retracted. When the fixed plate 3 is retracted, the butterfly 4 is moved to the sewing machine 13. It moves to the wrapping work position wrapped with thread 14.

상기 고정판(3)이 후진하게 되면 모터(9)가 회전하고 이의 회전축(10)은 구동롤(11)을 회전시킴에 따라 상기 나비드(4)는 도 1의 화살표 방향인 반시계 방향으로 회전하게 되는데, 이때 회전하는 나비드(4)와 니들(12)의 재봉으로 실(14)이 이 나비드(4)를 도 3과 같이 감싸 랩핑 시키게 된다.When the stationary plate 3 is reversed, the motor 9 rotates and its rotary shaft 10 rotates the driving roll 11, so that the butterfly 4 rotates counterclockwise in the direction of the arrow of FIG. In this case, the thread 14 is wrapped around the butterfly 4 as shown in FIG. 3 by sewing the rotating butterfly 4 and the needle 12 to wrap.

이와 아울러 상기 나비드(4)에서 재봉된 실(14)에서 재봉된 실(14)의 풀림을 방지하기 위해 실(14)의 랩핑 완료후 에어실린더(15)에 의해 작동하는 히터 커팅부(16)가 전진하여 실(14)을 절단하고 나비드(4)에 이 실(14)을 밀착 부착시킨다.In addition, the heater cutting unit 16 operated by the air cylinder 15 after completion of lapping of the thread 14 to prevent loosening of the thread 14 sewn from the thread 14 sewn from the butterfly 4. ) Advances to cut the thread 14 and attaches the thread 14 to the butterfly 4 in close contact.

이러한 작업이 완료되면, 상기 고정판(3)의 에어실린더(2)가 전진하고 압착롤(8)이 상승하게 되어 실로 랩핑된 나비드(4)를 취출하게 되면 작업은 완료된다.When this operation is completed, the air cylinder (2) of the fixed plate 3 is advanced and the pressing roll (8) is raised to take out the butterfly 4 wrapped with thread, the operation is completed.

상기와 같이 일렬비드의 구조변형 방지를 위한 실 랩핑장치는 나비드의 안정성 확보와 가류후 변형을 방지하고, 타이어의 내구성 향상에도 기여하는 잇점을 갖는다.As described above, the seal wrapping device for preventing structural deformation of the in-line bead has the advantage of securing the stability of the butterfly and preventing deformation after vulcanization, and contributes to improving the durability of the tire.
