The eccentric roller is arranged on the steel strip transfer path at the outlet side of the correcting rollers.

Description

언코일러용 레벨러 {Leveller of the uncoiler}Leveler for the uncoiler {Leveller of the uncoiler}

본 발명은 언코일러용 레벨러에 관한 것으로서, 좀 더 상세히는 언코일러에 거치된 코일로부터 풀려나오는 강판을 용도에 따라 곡률을 부여할 수 있는 새로운 구조의 언코일러용 레벨러에 관한 것이다. The present invention relates to a leveler for an uncoiler, and more particularly, to a leveler for an uncoiler having a new structure capable of imparting curvature to a steel sheet released from a coil mounted on an uncoiler according to a use.

언코일러는 강판 제조라인에서 생산된 강판코일을 거치하여, 이 코일로부터 강판을 풀어내기 위한 장치이다. 이러한 언코일러장치는 코일이 끼워져서 회전되는 지지드럼이 장착된 언코일러유닛과 이 지지드럼의 일측에 배치되며 다수열의 롤러가 상하로 배치되는 레벨러유닛을 포함한다. 이러한 언코일러장치는 코일이 감긴 강판을 풀어내면 상당한 곡률을 갖고 만곡된 상태로 인출되므로 이러한 강판을 사용하기에 적합하도록 레벨러유닛을 통과시키면서 평탄하게 교정하게 된다.The uncoiler is a device for unwinding the steel sheet from the coil through the steel sheet coil produced in the steel sheet manufacturing line. Such an uncoiler device includes an uncoiler unit equipped with a support drum in which a coil is inserted and rotated, and a leveler unit disposed on one side of the support drum and having a plurality of rows of rollers arranged up and down. Such an uncoiler device has a considerable curvature and is drawn out in a curved state when the coiled coil is unrolled, so that the uncoiler is straightened while passing through the leveler unit to be suitable for use of the steel sheet.

그런데, 이러한 언코일러장치는 언코일러유닛에서 풀려나온 강판을 레벨러유닛을 거치면서 평탄하게 교정하기 때문에, 이러한 레벨러유닛을 통과한 강판을 제품의 용도나 고객의 요구에 따라 일정한 곡률을 부여해야 하는 경우에는, 강판에 곡률을 부여하기 위한 별도의 후공정이 필요하다. 이와 같이 언코일러장치를 거친 강판에 일정한 곡률을 부여하기 위해 후공정을 거치는 것은 작업이 번거롭고 비효율적이라는 문제점이 있었다.However, since the uncoiler device straightens the steel sheet released from the uncoiler unit through the leveler unit, it is necessary to give a certain curvature to the steel sheet passing through the leveler unit according to the use of the product or the customer's request. Requires a separate post-process for imparting curvature to the steel sheet. In this way, the post-process to give a constant curvature to the steel sheet subjected to the uncoiler has a problem that the work is cumbersome and inefficient.

본 발명은 전술한 바와 같은 종래의 언코일러장치의 문제점에 착안하여 제안된 것으로서, 본 발명은 언코일러에서 풀려나오는 강판을 평탄하게 교정할 수 있으면서도 필요에 따라 강판에 원하는 곡률을 부여할 수 있는 새로운 구조의 언코일러용 레벨러를 제공하고자 하는 것이다.The present invention has been proposed in view of the problems of the conventional uncoiler device as described above, and the present invention is capable of flattening the steel sheet released from the uncoiler while providing a new curvature to the steel sheet as needed.

As shown, according to the present invention, an uncoiler unit 1 having a support drum 4 on which the coil 2 is mounted, and a leveler unit disposed on one side from which the steel sheet of the uncoiler unit 1 is drawn out. (10). The leveler unit 10 includes a plurality of upper rollers 14 and the lower roller 12, the calibration roller 11 is arranged in parallel up and down. At the front and rear ends of the straightening roller 11, guide rollers 16 and 17 supporting the conveyed steel sheet are disposed to advance the steel sheet. The upper portion of the leveler unit 10 includes a drive mechanism 18 including a drive motor or a hydraulic cylinder for pressing or rotating the plurality of rollers.

이러한 언코일러유닛(1)의 교정롤러(11)의 배출단에는 강판의 이송경로상에 배치되는 편심롤러(20)가 구비된다. 이 편심롤러(20)는 그 샤프트(21)의 일측에 결합되는 수동조작핸들(22)에 의해 회전됨으로써, 강판의 이송경로에 대하여 출몰됨 으로써, 이송경로로 진입하거나 후퇴될 수 있도록 구성된다. 이에 따라, 만일 편심롤러(20)가 상승하여 강판의 이송경로 쪽으로 진입하면, 교정롤러(11)를 통해 평탄하게 교정되어 나오는 강판(3)이 편심롤러(20)에 의해 상향으로 휘어짐으로써 적절한 곡률을 갖도록 된다. 교정롤러(11)가 위로 상승하면 할수록 강판(3)의 휘어지는 정도는 크게 될 것이다. 그리고 편심롤러(20)를 회전시켜서 강판 이송경로로부터 퇴피시키면, 강판(3)은 교정롤러(11)에 의해 평탄하게 교정된 상태로 이송되게 된다. 편심롤러(20)의 후단에는 이송되는 강판(3)을 지지하는 가이드롤러(17)가 배치된다.At the discharge end of the straightening roller 11 of the uncoiler unit 1, an eccentric roller 20 disposed on a feed path of the steel sheet is provided. The eccentric roller 20 is rotated by the manual operation handle 22 coupled to one side of the shaft 21, so that it can be retracted with respect to the transport path of the steel sheet, so that it can enter or retreat to the transport path. Accordingly, if the eccentric roller 20 rises and enters the conveying path of the steel sheet, the steel sheet 3 that is straightened straight through the straightening roller 11 is bent upward by the eccentric roller 20 so as to have an appropriate curvature. To have. As the straightening roller 11 rises up, the degree of warpage of the steel sheet 3 will increase. When the eccentric roller 20 is rotated and retracted from the steel sheet conveying path, the steel sheet 3 is conveyed in a state of being flatly corrected by the straightening roller 11. At the rear end of the eccentric roller 20, a guide roller 17 for supporting the conveyed steel sheet 3 is disposed.

한편, 상기 편심롤러(20)의 샤프트(21)의 일측에는 수동조작용 핸들(22)이 결합되어, 운전자가 수동으로 편심롤러(20)를 회전시켜서 승강조절할 수 있다. 이를 위해, 핸들(22)에는 제1 웜휠(24)이 축결합되고, 이 제1 웜휠(24)에는 제1 웜기어(25)가 치합되고, 이 제1 웜기어(25)에는 제2 웜기어(26)가 동축적으로 축결합되고 이 제2 웜기어(26)에는 제2 웜휠(27)이 치합되어, 이 제2 웜휠(27)에 상기 편심롤러(20)의 샤프트(21)가 결합된다. 이와 같이, 핸들(22)과 편심롤러(20) 사이에 웜과 웜휠기구로 이루어진 동력전달기구를 사용함으로써, 충분한 변속비를 얻을 수 있으며, 이에 따라 작은 힘으로도 편심롤러(20)를 회전조작할 수 있다. 더욱이 본 발명에 따르면, 이러한 웜과 웜휠기구를 이중으로 사용함으로써, 더욱 작은 힘으로 큰 회전력을 발휘할 수 있다. On the other hand, the manual operation handle 22 is coupled to one side of the shaft 21 of the eccentric roller 20, the driver can manually adjust the lift by rotating the eccentric roller 20. To this end, the first worm wheel 24 is axially coupled to the handle 22, and the first worm gear 25 is engaged with the first worm wheel 24, and the second worm gear 26 is attached to the first worm gear 25. ) Is coaxially axially coupled to the second worm gear 26 and the second worm wheel 27 is engaged, and the shaft 21 of the eccentric roller 20 is coupled to the second worm wheel 27. Thus, by using a power transmission mechanism consisting of a worm and a worm wheel mechanism between the handle 22 and the eccentric roller 20, a sufficient speed ratio can be obtained, thereby rotating the eccentric roller 20 with a small force. Can be. Furthermore, according to the present invention, by using the worm and the worm wheel mechanism in duplicate, it is possible to exert a large rotational force with a smaller force.
