Description

언코일러 {Uncoiler}Uncoiler {Uncoiler}

본 발명은 언코일러에 관한 것으로서, 좀 더 상세히는 거치된 코일을 회전시켜서 원활한 동작으로 코일로부터 강판을 풀어서 원하는 이송위치로 이송할 수 있도록 된 새로운 구조의 언코일러에 관한 것이다.The present invention relates to an uncoiler, and more particularly, to a uncoiler of a new structure that can be moved to a desired transfer position by releasing a steel sheet from the coil in a smooth operation by rotating the mounted coil.

언코일러는 코일 형태로 감겨서 공급되는 강판(이하에서 '코일'이라 칭함)으로부터 강판을 풀어서 인출하여 이송하는 장치이다. 종래의 언코일러는 코일을 확장가능한 지지드럼에 삽입하고, 강판의 선단부를 픽업하여 인접배치된 레벨러의 교정롤러 사이를 통과시키면서 강판을 평단하게 교정하였다. 그런데 강판의 중량이 상당히 크고 잘 휘어지지 않기 때문에, 코일로부터 강판의 선단을 인출하여 레벨러로 도입하는 일이 용이하지 않으며, 이에 따라 언코일러에 코일을 설치한 후에 강판을 인출하여 평탄화시켜서 뽑아내는 과정이 복잡하고 힘이 많이 드는 문제점이 있었다.The uncoiler is a device that unwinds the steel sheet from the steel sheet (hereinafter referred to as 'coil') supplied by winding it in coil form and draws it out. The conventional uncoiler straightens the steel sheet while inserting the coil into the expandable support drum, picking up the tip of the steel sheet and passing it between the calibration rollers of adjacently arranged levelers. However, since the weight of the steel sheet is quite large and does not bend well, it is not easy to draw the tip of the steel sheet from the coil and introduce it to the leveler. There was a complicated and laborious problem.

본 발명은 전술한 바와 같은 종래의 언코일러의 문제점에 착안하여 제안된 것으로서, 본 발명은 언코일러에 거치된 코일로부터 강판의 선단을 픽업하여 용이하게 인접하는 레벨러로 도입시킬 수 있어서 강판의 언코일작업이 신속하고 용이한 새로운 구조의 언코일러를 제공하고자 하는 것이다.The present invention has been proposed in view of the problems of the conventional uncoiler as described above, and the present invention can pick up the front end of the steel sheet from the coil mounted on the uncoiler and easily introduce it into the adjacent leveler to uncoil the steel sheet. The aim is to provide an uncoiler with a new structure that is quick and easy to work with.

그리고 상기 레벨러(30)의 도입부의 상부에는 상부가이드(46)의 기단부가 실린더(47)에 의해 회동가능하게 장착된다. 이 상부가이드부(46)도 신축가능한 아암 또는 플레이트로 이루어져서 실린더(48)에 의해 신축된다. 그리고 이 상부가이드(46)의 선단부는 뾰쪽하게 형성된다. 상기 실린더(47)와 실린더(48)는 상부가이드구동부를 이루어서, 상부가이드(46)를 회동시켜서 그 선단부를 코일(2)의 제1 점(4)보다 높은 위치의 제2 점(5)에 접근시킨다.The base end of the upper guide 46 is rotatably mounted by the cylinder 47 on the upper portion of the introduction portion of the leveler 30. The upper guide portion 46 is also made of a stretchable arm or plate, which is stretched by the cylinder 48. And the tip end of this upper guide 46 is formed pointed. The cylinder 47 and the cylinder 48 form an upper guide driving portion, and rotate the upper guide 46 so that its tip is positioned at the second point 5 at a position higher than the first point 4 of the coil 2. Approach

이러한 구성에 따라, 코일(2)이 지지드럼(12)에 삽입되어 거치된 후에, 구동롤러(26)를 회전시켜서 이에 마찰접촉되는 코일(2)을 서서히 회전시켜서, 코일(12)에 감긴 강판(3)의 선단부가 상게 제1 점(4)과 제2 점(5) 사이에 위치되도록 한다. 그 후에, 상기 하부가이드(42)를 회동시키고 신장시켜서 그 선단부의 가이드롤러(45)가 코일(2)의 하부 둘레부의 제1 점(4), 즉 강판(3)의 선단부(5) 위치보다 아래쪽에 접촉시키고, 상기 하부가이드(42)를 회동시키고 신장시켜서 그 선단부가 코일(2)의 제2 점, 즉, 강판(3)의 선단부(5) 위치보다 위쪽 위치에 근접시킨다. 그리고 코일(2)의 결속밴드를 절단하여 제거하면, 강판(3)의 선단부가 상부가이드(52)와 하부가이드(42) 사이에서 안내되고, 구동롤러(26)와의 마찰접촉에 의해 코일(2)의 강판이 이송되어 레벨러(30)의 상하 롤러(33,34) 사이로 진입하여 이송되면서 평탄화되게 된다.According to this configuration, after the coil 2 is inserted into the supporting drum 12 and mounted thereon, the driving roller 26 is rotated to gradually rotate the coil 2 in friction contact therewith, and thus the steel sheet wound on the coil 12. The tip of (3) is positioned between the first point 4 and the second point 5 on the top. Thereafter, the lower guide 42 is rotated and extended so that the guide roller 45 at the tip end thereof is smaller than the position of the first point 4 at the lower circumference of the coil 2, that is, at the tip end 5 position of the steel plate 3. The lower guide 42 is rotated and extended so that its tip portion is closer to the position higher than the second point of the coil 2, that is, the position of the tip portion 5 of the steel plate 3. When the binding band of the coil 2 is cut off and removed, the tip of the steel sheet 3 is guided between the upper guide 52 and the lower guide 42, and the coil 2 is brought into frictional contact with the driving roller 26. ) And the steel sheet is transported to enter between the upper and lower rollers 33 and 34 of the leveler 30 to be flattened.
