본 발명은 후프를 코일로 감아주는 후프 권취기에 관한 것으로, 더욱 상세하게는 후프에 걸리는 텐션을 균일하게 유지하여 후프가 들쭉날쭉 감겨지는 텔레스코프 현상을 없애 선단부터 끝단까지 균일하게 감겨질 수 있도록 한 후프 권취기의 코일 텐션유지 및 유도장치에 관한 것이다.The present invention relates to a hoop winder for winding a hoop into a coil, and more particularly, to maintain a uniform tension on the hoop so that the hoop can be uniformly wound from the end to the end by eliminating the jagged telescope phenomenon. It relates to a coil tension holding and induction device of a winder.

일반적으로 후프는 두께와 폭이 각각 3mm이하, 600mm미만으로 된 띠모양의 강판으로 통상 스트립밀로 압연한 광폭강대(600mm 이상)를 슬리팅(slitting)하여 제조된다.In general, the hoop is manufactured by slitting a wide strip (600 mm or more), which is usually rolled with a strip mill, in a strip-shaped steel sheet having a thickness and width of less than 3 mm and less than 600 mm, respectively.

이러한 후프는 절판으로도 출하되나, 대개는 코일로 감아져 출하된다. These hoops are also shipped out of print, but are usually shipped in coils.

후프 권취기는 상기와 같은 후프를 코일로 감아주기 위한 장치로서, 도 5에 도시된 바와 같이, 권취기의 하우징(100) 일측에는 후프(200)를 감아 말기 위한 텐션릴(102)과 텐션릴(102)에 감겨지는 후프(200)을 눌러 지지하기 위한 홀드롤(106)이 설치되고, 권취기 앞쪽에 위치하여 후프(200)를 진행시키는 핀치롤(120)이 설치되는 프레임(104)에는 후프(200)를 받쳐주기 위한 테이블(108)이 설치되며, 프레임(104) 앞쪽에는 슬리터에 의해 폭방향으로 절단된 다수개의 후프(200)를 정렬시키기 위한 세퍼레이터(110)가 설치된 구조로 되어 있다.The hoop winder is a device for winding the hoop as described above, and as shown in FIG. 5, a tension reel 102 and a tension reel 102 for winding the hoop 200 on one side of the housing 100 of the winder. Hold hoop 106 for pressing and supporting the hoop 200 wound around 102 is installed, the frame 104 is installed on the frame 104 is installed in the front of the winder pinch roll 120 to advance the hoop 200 A table 108 for supporting the 200 is installed, and a separator 110 for aligning the plurality of hoops 200 cut in the width direction by the slitter in the front of the frame 104 is installed. .

따라서 압연기를 통과한 스트립은 슬리터를 거쳐 다수개의 후프로 절단된 후 텐션릴에 감기게 되는 데, 완전히 감기게 되면 텐션릴 하부에 위치하고 있는 코일카에 의해 후공정으로 이송된다.Therefore, the strip passing through the rolling mill is cut into a plurality of hoops through the slitter and then wound on the tension reel. When the coil is completely wound, the strip is transferred to the post process by the coil car located under the tension reel.

그런데 상기한 종래의 후프 권취기는 후프 끝단이 세퍼레이터를 지난 후에는 후프의 끝단을 지지할 수 없게 되어 후프가 텐션릴에 바르게 감기지 않고 들쭉날쭉 하게 감기는 텔레스코프 현상이 발생하는 문제점이 있었다.However, the conventional hoop winder has a problem in that a telescope phenomenon in which the hoop is wound up without being wound on the tension reel is not able to support the tip of the hoop after the hoop end passes the separator.

즉, 세퍼레이터로부터 텐션릴까지는 통상 코일에 1-2번 정도 감기는 길이의 후프가 놓여지는 데, 이 후프의 끝단이 지지되지 않은 체로 텐션릴에 계속 감김에 따라 텔레스코프가 발생하게 되는 것이다.That is, a hoop having a length of about 1-2 turns is usually placed from the separator to the tension reel, and the telescope is generated as the end of the hoop continues to be wound around the tension reel without being supported.

따라서 종래에는 후프의 끝단 권취시 작업자 2,3인이 조를 이루어 수시로 텔레스코프된 후프를 교정하면서 권취작업을 하였는 데, 먼저 홀드롤을 상승시키고, 작업자가 후프 끝단을 잡고 누르는 상태에서 다른 작업자가 적당한 치구를 이용하여 좌우측으로 텔레스코프되어 권취된 후프 에지부를 두드리며 정열시킨 후 다시 홀드롤을 하강시켰었다.Therefore, in the related art, when winding the end of the hoop, two or three workers were tightened to perform the winding work while correcting the telescopic hoop from time to time. First, the hold roll was raised, and the other worker held the hoop end and pressed it. The hold roll was lowered again by aligning by tapping the hoop edge wound around the telescope left and right using an appropriate jig.

그러나 이러한 작업은 후프 끝단의 유동에 의해 인명피해가 발생할 소지가 대단히 높으며, 작업이 순조롭지 못하여 성과가 미비하였을 뿐아니라 재작업에 따른 시간과 인력이 낭비되는 문제점이 있게 되는 것이다.However, this work is very likely to cause human injury due to the flow of the hoop end, and the work was not smooth and the performance was insufficient, and the time and manpower of rework were wasted.

이에 본 발명은 상기한 문제점을 해결하기 위하여 안출된 것으로, 텐션릴 최단거리에서 후프를 개별 유도함으로써, 후프가 텐션릴에 엉킴없이 권취되고, 텐션릴에 감기는 후프의 양 측면이 가이드 디스크에 의해 정확히 안내되어 감기도록 함으로서, 코일 외경에 발생된 텔레스코프를 안전하고 쉽게 교정할 수 있도록 한 후프 권취기의 코일 텐션유지 및 유도장치를 제공함에 그 목적이 있다.Accordingly, the present invention has been made to solve the above problems, by guiding the hoop individually at the shortest distance to the tension reel, the hoop is wound up without tension in the tension reel, both sides of the hoop wound on the tension reel by the guide disk It is an object of the present invention to provide a coil tension holding and induction device of a hoop winder, which can safely and easily correct a telescope generated in an outer diameter of a coil by being accurately guided and wound.

상기한 바와 같은 목적을 달성하기 위한 본 발명은, 텐션릴 설치 프레임의 상단과 하단에 설치되어 스트립의 상하면에 위치하는 홀더판과 테이블 상에 각각 설치되어 스트립의 상하면을 밀착 지지하기 위한 텐션부와, 상기 홀더판에 설치되어 텬션릴에 감기는 후프를 코일에 밀착시킬 수 있도록 된 밀착부를 포함한다.The present invention for achieving the object as described above, is installed on the top and bottom of the tension reel installation frame and the holder plate positioned on the upper and lower surfaces of the strip, respectively, the tension portion for closely supporting the upper and lower surfaces of the strip and And an adhesion part installed on the holder plate to closely adhere the coil to the coil.

이에 따라 후프 끝단은 텐션부에 지지되고 텐션부를 지난 후프는 밀착부에 의해 텐션릴에 밀착된 상태로 감기게 됨으로써, 텔레스코프 현상 발생 없이 항상 일정하게 텐션릴에 감길 수 있게 되는 것이다.Accordingly, the end of the hoop is supported by the tension portion, and the hoop passing through the tension portion is wound in a state in which the contact portion is in close contact with the tension reel, so that the telescopic phenomenon may be constantly wound on the tension reel at all times.

Each of the driving cylinders 51 installed on the table 30 is individually extended to bring the lower felt 52 into close contact with the upper felt 56.

구동실린더(51)가 신장작동되면 구동실린더의 피스톤로드 선단에 설치된 반원형 밀착블럭(50)은 위쪽으로 상승하면서 밀착블럭(50)을 덮어 씌우고 있는 하부펠트(52)를 홀더판(10)에 설치된 상부펠트(56)쪽으로 밀어올리게 된다. 이에 따라 상부펠트(56)와 하부펠트(52) 사이에 위치한 후프가 상하부펠트 사이에 밀착지지된다.When the driving cylinder 51 is extended and operated, the semi-circular contact block 50 installed at the tip of the piston rod of the drive cylinder is upwardly upward and the lower felt 52 covering the contact block 50 is installed on the holder plate 10. It is pushed toward the upper felt (56). Accordingly, the hoop located between the upper felt 56 and the lower felt 52 is closely supported between the upper and lower felt.

따라서 후프(200)는 핀치롤(120)을 지난 상태에서도 상하부펠트(56,52)와 상하부디프렉트롤(60,61)에 의해 밀착지지되어 장력이 계속유지된 체 텐션릴에 감기게 되는 것이다.Therefore, the hoop 200 is held in close contact with the upper and lower felts 56 and 52 and the upper and lower direct rolls 60 and 61 even after the pinch roll 120 is wound on the sieve tension reel whose tension is maintained. .

한편, 메인실린더(20)와 구동실린더(51)가 신장작동함과 더불어 홀더판(10)에 설치되어 있는 작동실린더(72)가 신장작동되어 지지부재(70)를 회동시키게 된다.On the other hand, while the main cylinder 20 and the driving cylinder 51 is extended, the operation cylinder 72 installed on the holder plate 10 is extended to rotate the support member 70.

지지부재(70)가 회동됨에 따라 지지부재 선단에 설치되어 있는 홀드롤(71)이 텐션릴(102)에 감겨지는 코일의 상부에 밀착되어 코일로 감기는 후프(200)를 눌러주게 된다.As the support member 70 is rotated, the hold roll 71 installed at the front end of the support member is pressed against the upper portion of the coil wound around the tension reel 102 to press the hoop 200 wound around the coil.

이렇게 홀드롤(71)에 의해 후프가 적당한 압력으로 눌려지면서 코일로 감겨 짐에 따라 핀치롤을 지나 상하부 디프렉트롤을 통과한 후프의 끝부분이 텐션릴에 완전히 감길때까지 후프가 느슨해지는 것을 방지할 수 있고, 이에 따라 텔레스코픽 현상을 방지할 수 있게 되는 것이다.As the hoop is pressed to the appropriate pressure by the hold roll 71, the hoop is prevented from loosening until the tip of the hoop passing through the pinch roll and the upper and lower deflect roll is completely wound on the tension reel. In this way, it is possible to prevent the telescopic phenomenon.

이상 설명한 바와 같이 본 발명에 따른 후프 권취기의 코일 텐션유지 및 유도장치에 의하면, 코일로 감기는 후프의 끝단을 정확히 지지안내하여 텐션릴에 감기도록 함으로서 코일의 텔레스코프 현상을 방지할 수 있다.As described above, according to the coil tension holding and induction device of the hoop winder according to the present invention, the end of the hoop wound by the coil can be accurately guided and wound on the tension reel to prevent the telescope phenomenon of the coil.

또한, 후프의 권취불량으로 인한 코일의 에지결함을 방지하고, 겹쳐져 감겨진 코일을 분리하는 작업을 불필요하게 되어 안전사고의 위험을 방지할 수 있게 된다.

In addition, it is possible to prevent the edge defect of the coil due to the winding of the hoop, and to remove the overlapping coil is unnecessary work to prevent the risk of safety accident.
