본 발명은 띠강판을 길이방향으로 복수개 분할, 재단한 슬릿(Slit) 띠강판(이하, 슬릿 스트립이라 함.)을 권취할 때 각 슬릿 스트립의 권취 장력이 균일하게 부여될 수 있도록 한 슬릿 스트립의 권취장력 부여장치에 관한 것이다.The present invention is to provide a winding tension of each slit strip so that the winding tension of each slit strip can be uniformly applied when winding the slit strip steel plate (hereinafter referred to as slit strip) which is divided and cut a plurality of strip steel plates in the longitudinal direction. It relates to a winding tension imparting device.

일반적으로 띠강판을 복수개로 분할 재단한 슬릿 스트립을 권취하는 슬릿 라인에는 소폭으로 절단된 슬릿 스트립에 발생되는 권취 장력의 불균형을 해소하여 균일한 권취장력으로 원활하고 안정된 권취작업이 수행될 수 있도록 하기 위한 장력 부여장치가 설치된다.   In general, the slit line which winds up the slit strip divided into slit strips in plural strips solves the unbalance of the winding tension occurring in the slit strip which is cut slightly so that the smooth and stable winding work can be performed with uniform winding tension. Tension imparting device is installed.

슬릿 스트립의 권취장력 불균형은 각 슬릿 스트립의 두께 편차나 길이 편차 등으로인해 발생되며, 이로 인해 권취기에 코일상으로 감기는 슬릿 스트립의 각 권취직경이 다르게 되어 권취 불량과 함께 슬릿 스트립의 형상불량 등이 발생된다.   Unbalance of winding tension of slit strip is caused by thickness variation or length deviation of each slit strip, and as a result, the winding diameter of the slit strip wound into coils on the winder is different so that the winding failure and the shape of the slit strip are poor. Is generated.

기존 권취장력 부여장치로는 롤러 브라이들(Roller Bridle)이 방식과 텐션 패트(Tension Pat)방식 등이 알려져 있으나, 롤러 브라이들방식은 소폭으로 절단된 각 슬릿 스트립을 권취기에 감을 때 슬릿 스트립의 두께 편차에 적절히 대응하지 못함으로써 슬릿 스트립의 권취장력 불균형으로 권취기에 타원형으로 감기거나 되감기가 불가능한 등의 문제가 있었다.   Conventional winding tension applying device is known as roller bridle method and tension pat method, but roller bridle method is the thickness of the slit strip when winding each slit strip cut into narrow windings There was a problem that the winding tension of the slit strip is unbalanced and the winding is not elliptical or cannot be rewound due to the failure to adequately cope with the deviation.

즉, 소폭으로 재단된 슬릿 스트립은 그 두께가 불균일할 수 밖에 없는 데, 롤러 브라이들 방식은 수개의 롤러에 슬릿 스트립을 동시에 감아 붙여서 롤러에 연결된 브레이크장치의 제동력에 의한 마찰저항으로 각 슬릿 스트립의 불균일한 두께에 관계없이 일정한 마찰저항이 부여되어 균일한 권취장력을 부여하지 못하게 됨으로써 각 슬릿 스트립이 고르게 권취되지 못하고 불균일하게 권취되는 권취불량이 발생하는 것이었다.  In other words, the narrowly cut slit strips are inevitably non-uniform in thickness. The roller bridal method winds the slit strips on several rollers at the same time, so that the frictional resistance of the brake device connected to the rollers causes frictional resistance of each slit strip. Regardless of the non-uniform thickness, constant frictional resistance was applied to prevent the uniform winding tension from being applied, resulting in a winding failure in which each slit strip was not wound evenly and was unevenly wound.

또, 텐션 패트 방식은 슬릿 스트립을 권취릴에 공급하는 도중에 텐션 패트를 설치하여 각 슬릿 스트립에 압력을 가함으로써 권취 장력을 부여하는 것으로, 이러한 텐션 패트 방식은 패트의 펠트재가 슬릿 스트립의 표면을 압착하여 마찰저항을 부여하는 과정에서 권취장력으로 인한 표면 흠집을 발생시키는 문제가 있었다.   In addition, the tension pad method provides a tensioning force by installing a tension pad and applying pressure to each slit strip while supplying the slit strip to the winding reel. In this tension pad method, the felt material of the pad presses the surface of the slit strip. In the process of imparting frictional resistance, there was a problem of generating surface scratches due to the winding tension.

그리고, 상기한 기존 권취장력 부여장치의 문제를 해결하기 위하여 슬릿 스트립을 상하면으로 부터 압착하여 균등한 장력을 부여하고 슬릿 스트립 표면에 흠집이 생기지 않도록 하는 권취 장력 부여장치가 특허공고 제85-001053호에 알려져 있으며, 슬릿 스트립의 두께 편차에 따라 동일한 조건에서 자동으로 후퇴하면서 안내되게 하여 슬릿 스트립이 권취되도록 한 자동 후퇴식 세퍼레이터 부착 디플렉터 롤 장치가 특허 제0135058호에 공지되어 있고,   And, in order to solve the problem of the existing winding tension imparting device, the winding tension imparting device for compressing the slit strip from the upper and lower surfaces to give an even tension and to prevent scratches on the surface of the slit strip is disclosed in Patent Publication No. 85-001053 Known in Korean Patent No. 0135058, a deflector roll device with an automatic retractable separator, which is guided while retracting automatically under the same conditions according to the thickness variation of the slit strip, is wound.

슬릿 스트립이 권취되는 권취장치의 회전구동축 외주에 분할권취링을 장착하고 내부에 유체를 넣어 유체압으로 압압되는 복수의 분할 압압편을 설치하여 유체압으로 압압되는 분할압압편에 의해 각 분할권취링의 내주면을 압압하여 각 분할권취링에 권취되는 슬릿 스트립에 균일한 권취장력을 부여토록 한 장치가 일본특개소 5-104140호에 알려져 있다.   The split winding ring is mounted on the outer circumference of the rotary drive shaft of the winding device in which the slit strip is wound, and a plurality of split pressing pieces that are pressurized by the fluid pressure by putting the fluid therein are divided by the divided press pieces that are pressed by the fluid pressure. A device is known in Japanese Patent Laid-Open No. 5-104140 that presses the inner circumferential surface of the slit to give uniform winding tension to the slit strip wound around each split winding ring.

이밖에 권취릴에 권취되는 슬릿 스트립에 균일한 권취장력을 부여하기 위한 장치로 일본특허공고 소51-35458호, 일본특허공개 소56-136748호, 일본특허공개 평5-104140호 등이 공지되어 있으며,   In addition, Japanese Patent Publication No. 51-35458, Japanese Patent Publication No. 56-136748, and Japanese Patent Publication No. 5-104140 are known as a device for imparting uniform winding tension to the slit strip wound on the winding reel.

한편, 전술한 권취장력 부여장치와는 다르게 각 슬릿 스트립의 두께 편차, 길이 편차에 의해 발생되는 권취장력의 편차가 없도록 권취판에 압력을 일정하게 하여 안정적으로 권취가 수행되도록 권취기를 개량한 슬릿 스트립의 권취장치가 공개특허 제10-2004-0096470호에 알려져 있다.   On the other hand, unlike the aforementioned winding tension imparting device, the slit strip improved by the winding machine so that the winding is stably performed by keeping the pressure constant on the winding plate so that there is no variation in the winding tension caused by the thickness variation and the length variation of each slit strip. A winding device of is known from Korean Patent Publication No. 10-2004-0096470.

The frictional resistance is individually received from each of the tension disks 11 and 11 'coupled to the drive shafts 12 and 12a of the 16 and 16a.

즉, 각 슬릿 스트립(S)은 그 두께 편차 등에 따라 텐션 디스크(11,11')로부터 개별적으로 그에 상응하는 독립적인 마찰저항을 받게 된다.That is, each of the slit strips S receives the respective independent frictional resistances from the tension disks 11 and 11 'individually according to their thickness variations.

양 스틸 드럼(1,1a) 사이에서 경유되는 슬릿 스트립(S)는 두께가 얇은 부분은 텐션 디스크(11,11')와 적은 마찰저항을 받게 되고, 반대로 두터운 부분은 높은 마찰저항을 받게 되므로 슬릿 스트립(S)은 그 두께편차 등에 따라 개별적으로 대응하는 텐션 디스크(11,11')에 의해 각 슬릿 스트립(S)이 그 두께 편차 등에 따른 마찰저항을 받아 디플렉터 롤 장치부(20)측으로 안내되므로 권취기(30)에서 각 슬릿 스트립(S)을 균일한 권취장력으로 권취시킬 수 있게 되는 것이다.The slit strip S passing through both steel drums 1 and 1a has a low frictional resistance with the tension disks 11 and 11 'with a thin portion, whereas the thick portion receives a high frictional resistance with a slit. The strip S is guided to the deflector roll device 20 by receiving the frictional resistance according to the thickness variation or the like by the tension disks 11 and 11 'corresponding to the thickness deviations, respectively. In the winder 30, each slit strip S is to be wound with a uniform winding tension.

이를 다시 살펴보면, 권취기(30)에 권취되는 슬릿 스트립(S)을 각 슬릿 스트립(S)의 두께 편차 등에 따라 스틸 드럼(1,1a)의 텐션 디스크(11,11')가 그에 상응하는 각기 다른 마찰저항으로 슬릿 스트립(S)을 잡아 당겨서 권취기(30)에 균일한 권취장력을 부여함으로써 슬릿 스트립(S)이 일부가 느슨하게 감기는 등의 권취 불량을 해소하게 되는 것이다. Referring to this again, the tension disks 11 and 11 ′ of the steel drums 1 and 1 a correspond to the slit strips S wound around the winder 30 according to the thickness variation of the respective slit strips S, respectively. By pulling the slit strip S with different frictional resistance to give the winding machine 30 a uniform winding tension, the winding failure such as a part of the slit strip S being loosely wound is eliminated.

한편, 스틸 드럼(1,1a)의 구동축(12,12a) 일측에 형성된 에어실린더(17,17a)는 텐션 디스크(11,11')를 일방으로 가압하여 스틸 드럼(1,1a) 사이를 경유하는 슬릿 스트립(S)과의 마찰저항으로부터 발생되는 텐션 디스크(11,11')의 측압에 대응토록 하여 텐션 디스크(11,11') 사이에 라이닝(14,14')으로 형성된 유격이상으로 텐션 디스크(11,11') 사이가 유격되어 슬릿 스트립(S)에 원활한 권취장력이 제공되지 못하게 될 우려를 방지하게 된다.     On the other hand, the air cylinders 17 and 17a formed on one side of the drive shafts 12 and 12a of the steel drums 1 and 1a pressurize the tension disks 11 and 11 'to one side and pass through the steel drums 1 and 1a. The tension is greater than the clearance formed by the linings 14 and 14 'between the tension disks 11 and 11' in response to the side pressures of the tension disks 11 and 11 'resulting from the frictional resistance with the slit strip S. The gap between the discs 11 and 11 'is prevented so that a smooth winding tension cannot be provided to the slit strip S.

이상에서 살펴본 바와 같이 본 발명은 복수개의 슬릿 스트립(S)에 대응하는 복수개의 텐션 디스크(11,11')로 이루어지는 스틸 드럼(1,1a)을 구성하고 스틸 드럼(1,1a) 사이로 슬릿 스트립(S)이 경유하면서 두께 편차에 따라 그에 상응하는 독립적인 마찰저항을 받게 함으로써 권취기(30)가 슬릿 스트립(S)을 균일한 권취장력으로 권취시킬 수 있도록 하여 슬릿 스트립(S)의 권취 직경이 서로 다르게 권취되는 권취불량 등의 여러 문제를 해소하는 효과 등을 기대할 수 있다.As described above, the present invention constitutes a steel drum (1, 1a) consisting of a plurality of tension disks (11, 11 ') corresponding to the plurality of slit strips (S) and the slit strip between the steel drum (1, 1a) Winding diameter of the slit strip S by allowing the winder 30 to wind the slit strip S with a uniform winding tension by allowing S to receive an independent frictional resistance corresponding to the thickness variation while passing through it. The effect of solving various problems, such as a winding failure wound differently, can be expected.
