Description

타이어 부품용 고무시트 권취보빈의 록킹장치 {Locking Apparatus of Rubber Sheet Winding Bobbin for Tire}Locking Apparatus of Rubber Sheet Winding Bobbin for Tire}

본 발명은 타이어 제조공정에서 압출공정을 끝낸 각종 고무시트 압출물, 예를들어 트레드 또는 사이드윌을 보빈에 일정한 길이로 감아 권취할때 완전 권취된압출물이 보빈에서 풀어 이탈되어지는 것을 방지한 타이어 부품용 고무시트 권취보빈의 록킹장치에 관한 것으로, 특히 압출물이 권취된 보빈을 이동할때 자동으로 작용하는 록킹부에 의해 이 압출물이 보빈에서 이탈되어 풀어지는 것을 방지하는 고무시트 권취용 보빈의 록킹장치에 관한 것이다.The present invention is a tire that prevents the fully rolled extrudate from being released from the bobbin when winding the various rubber sheet extrudates, for example, tread or sidewill wound on the bobbin to a certain length after the extrusion process in the tire manufacturing process The present invention relates to a locking device of a rubber sheet winding bobbin for parts, and more particularly, to a rubber sheet winding bobbin which prevents the extruded product from being separated from the bobbin and released by a locking part that automatically works when the extrudate moves the wound bobbin. It relates to a locking device.

타이어 제조공정에서 압출공정은 정련공정에서 얻어진 고무시트를 이용하여 타이어 내부의 여러가지 고무부품들을 구금을 통하여 압출시켜 반제품인 고무시트의 압출물로 생산하는 공정으로, 압출기를 거친 고무시트는 알맞은 길이로 권취보빈에 권선된 상태로 다음공정인 재단공정으로 이동되어진다.In the tire manufacturing process, the extrusion process is a process in which various rubber parts inside the tire are extruded through detention using the rubber sheet obtained in the refining process to produce an extruded product of a semi-finished rubber sheet. As it is wound on the winding bobbin, it is moved to the next cutting process.

이와 같이 압출공정의 압출기에서 생상된 고무시트 압출물은 종래 도 2와 같이 일정길이까지 권취보빈(101)에 와인딩되어 공지의 커터에 의해 절단된 다음, 이 압출물의 끝부분까지 권취보빈(101)에 권취가 완료되면, 상기 권취보빈(101)은 와인딩지역(Winding Zone)에서 이동되는데, 이때 권취보빈(101)이 체인콘베이어상에서 이동하는 도중, 압출물이 권취된 보빈판(108)이 자중에 의해 회전하게 되고 이에 따라 권취된 압출물과 라이너(112)가 풀어져서 작업장 바닥에 닿은 채로 다음 공정으로 이동 운반되었다.As such, the rubber sheet extrudate produced by the extruder of the extrusion process is wound on the winding bobbin 101 to a predetermined length as shown in FIG. 2 and cut by a known cutter, and then wound bobbin 101 to the end of the extrudate. When the winding is completed, the winding bobbin 101 is moved in a winding zone, where the winding bobbin 101 moves on a chain conveyor, and the bobbin plate 108 on which the extrudate is wound And thus the wound extrudate and liner 112 were unwound and transported to the next process while touching the workshop floor.

즉 이러한 압출물의 끌림상태는 다량의 압출물의 불량과 라이너를 훼손하게 되는데, 이를 방지하기 압출물의 권취가 권취보빈(101)에서 완료되면, 이 권취보빈(101)이 체인콘베이어로 이동하기 전에 작업자가 스톱퍼(113)를 보빈판(108)의 구멍(114)에 삽입하여 이 권취보빈(1010의 회전을 방지하여 권취된 압출물을 보호하였다.That is, the drag state of the extrudate causes a large amount of the extrudate and damages the liner. To prevent this, if the winding of the extrudate is completed in the winding bobbin 101, the operator may move the winding bobbin 101 to the chain conveyor. A stopper 113 was inserted into the hole 114 of the bobbin plate 108 to prevent rotation of this winding bobbin 1010 to protect the wound extrudate.

그러나 상기와 같은 종래 권취보빈 잠금장치는 작업중 연속적인 작업흐름이 이루어지고 있는 설비근처로 작업자가 이동하여 잠금작업을 실시하여야 하기 때문에 안전사고의 위험성이 있으며, 설비의 자동화를 위하여 개선할 필요가 있었다.However, the conventional winding bobbin locking device has a risk of a safety accident because the worker must move to perform the locking work near the facility where the continuous working flow is made during the work, and it was necessary to improve the automation of the facility. .

이에 본 발명은 상기와 같은 종래 문제점을 해결하기 위해 발명된 것으로, 작업자에 의해 수동으로 이루어지는 권취보빈의 잠금과 해제 작동을 자동화시키어 안전사고와 장비의 성력화가 이루어지는 개선된 타이어 부품용 고무시트 권취보빈의 록킹장치를 제공함에 그 목적이 있다.Accordingly, the present invention has been invented to solve the conventional problems as described above, by automating the locking and unlocking operation of the take-up bobbin manually by the operator to improve the safety accidents and equipment performance rubber sheet winding bobbin for tire parts Its purpose is to provide a locking device.

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 타이어 부품용 고무시트 권취보빈의 록킹장치를 나타낸 도면으로서, 작동상태를 나타낸 것이다.1 is a view showing a locking device of a rubber sheet winding bobbin for a tire part according to the present invention, showing an operating state.

본 발명은 도면에 도시된 바와 같이 압출물인 고무시트가 권취보빈(1)에 와인딩되어 권취가 완료된 상태에서 이 압출물이 권취보빈(1)에서 이탈 되어지는 것을 방지하는 고무시트 권취보빈의 로킹장치에 있어서, 구동실린더(2)와, 상기 구동실린더(2)에 의해 힌지축(4)을 중심으로 회동하는 작동레버(3)와, 상기 힌지축(4)의 일측에 설치되어 작동레버(3)에 의해 연동되는 연동캠(5)과, 상기 연동캠(5)의 일측에 설치되어 연동캠(5)에 의해 회전되며 스프링(6)에 의해 탄력지지되는 회동레버(7)와, 상기 회동레버(7)의 회동반경내에 설치되어 회동레버(3)의 회전시 연동되어 보빈판(8)에 잠금작용을 일으키는 패드를 갖춘 록킹부(9)로 구성되어 있다.The present invention is a locking device of the rubber sheet winding bobbin to prevent the extruded rubber sheet is wound off the winding bobbin (1) as shown in the figure is wound off the winding bobbin (1) is the extruded from the winding bobbin (1) In the above, the driving cylinder (2), the operating lever (3) rotated about the hinge shaft (4) by the drive cylinder (2), and the operating lever (3) is provided on one side of the hinge shaft (4) The interlocking cam (5) interlocked by the), the rotating lever (7) is installed on one side of the interlocking cam (5) and rotated by the interlocking cam (5) and elastically supported by the spring (6) It is comprised in the locking part 9 provided with the pad which is provided in the rotation radius of the lever 7, and is interlocked at the time of rotation of the rotation lever 3, and makes a locking action to the bobbin board 8. As shown in FIG.

이와 같이 이루어진 본 발명은 권취보빈(1)에 압출물의 권치가 완료되어진 후 자중에 의해 이 권취보빈(1)의 역회전을 방지하도록 되어 있는바, 즉 권취가 완료된후 구동실린더(2)가 점선 방향으로 전진하여 작동레버(3)를 압착하게 되면, 이 작동레버(3)의 압착으로 힌지축(4)을 기준으로 연동캠(5)이 회동레버(7)를 압착하면서 회전하게 된다. 그러면, 회동레버(7)에 의해 상기 우레탄 패드를 갖춘 록킹부(9)가 보빈판(8)을 압착하게 되어 권취보빈(1)의 회전을 방지하게 된다.The present invention made as described above is to prevent the reverse rotation of the take-up bobbin 1 by its own weight after the winding of the extrudate to the take-up bobbin 1, that is, the drive cylinder (2) is dotted line after the winding is completed When the operating lever 3 is compressed in the direction, the interlocking cam 5 is rotated while pressing the rotating lever 7 based on the hinge shaft 4 by the pressing of the operating lever 3. Then, the locking part 9 with the urethane pad is pressed by the pivoting lever 7 to prevent the bobbin plate 8 from being rotated.

이때 여기서 상기 연동캠(5)은 회전후 회동레버(7)의 턱부위에 의해 스스로 원위치되지 않고 회전된 상태를 유지하면서 록킹부(9)가 보빈판(8)을 록킹시키게 되는 것이다.In this case, the interlocking cam 5 locks the bobbin plate 8 while the locking unit 9 is maintained by the jaw portion of the pivoting lever 7 after being rotated and not rotated by itself.

한편, 압출물을 권취보빈(1)에서 풀고자 하는 언록킹(Unlocking)작업을 할때 작업편의를 위해 해제실린더(10)가 록킹부(9)에 작용하게 되면, 이 록킹부(9)는 스프링(6)으로 탄지된 회동레버(7)를 회전축(11)을 중심으로 원위치시킴에 따라 권취보빈(1)의 보빈판(8)의 록킹이 해제되어 다음공정에서 압출물을 이용할 수 있게 된다.On the other hand, when the unlocking cylinder 10 acts on the locking portion 9 for the convenience of the work when the extruding object is to be released from the take-up bobbin 1, the locking portion 9 is By returning the pivoting lever 7 supported by the spring 6 about the rotary shaft 11, the locking of the bobbin plate 8 of the take-up bobbin 1 is released, so that the extrudate can be used in the next step. .

상기와 같이 본 발명은 이동중인 설비에서 고무시트를 와인딩한 권취보빈을 자동으로 록킹 및 언록킹시킬 수 있으므로 설비의 자동화를 도모하고 작업자의 안전사고를 방지하면서 성력화가 이루어지는 잇점 등이 있다.As described above, the present invention can automatically lock and unlock the winding bobbin wound with the rubber sheet in the moving equipment, thereby facilitating the automation of the equipment and preventing the safety accident of the worker.
