Description

권취코일의 내권부 풀림방지장치Inner part loosening prevention device of winding coil

본 고안은 권취코일의 내권부 풀림방지장치에 관한 것으로, 특히 냉간 압연시 텐션릴(Tension Reel)에 코일을 권취하는 과정에서 밀스탠드(Mill Stand) 내부의 코일이 파단되면 권취된 상태의 코일이 장력을 잃고 풀리게 되는데, 이때 누름롤을 이용하여 권취된 코일의 외권부를 신속하게 누름으로써 풀림현상을 미연에 방지할 수 있는 권취코일의 내권부 풀림방지장치에 관한 것이다.The present invention relates to a device for preventing the inner winding of the coiling coil, and in particular, when the coil in the mill stand is broken during the winding of the coil in the tension reel during cold rolling, the coil in the wound state is When the tension is lost and released, the present invention relates to a device for preventing the inner circumference of the winding coil which can prevent the phenomena of unwinding by pressing the outer winding of the coil wound quickly using the pressing roll.

일반적으로 냉간압연은 박판을 압연하는 설비로서 밀스탠드에서 철판을 압연하여 목표로 하는 두께와 형상을 만들고, 텐션릴에서 철판을 권취하여 제품을 생산하게 된다.In general, cold rolling is a facility for rolling a thin plate to produce a target thickness and shape by rolling the iron plate in the mill stand, and to produce the product by winding the iron plate in the tension reel.

그러나, 극박(두께 0.4㎜) 및 초극박(두께 0.23㎜이하)의 철판을 생산하는 작업중 스탠드 내부에서 스트립의 파단이 발생되면 텐션릴과 스탠드 사이의 스트립의 장력이 없어지면서 권취된 코일의 내권부가 느슨하게 풀리게 되고, 이 때문에 권취된 코일의 내권부가 겹쳐지면서 절단되어 제품으로서 사용할 수 없게 된다.However, if a breakage of the strip occurs inside the stand during the production of ultra-thin (0.4 mm thick) and ultra-thin (0.23 mm or less) steel sheets, the tension between the tension reel and the stand is lost and the inner coil of the coil wound up. Is loosened, which causes the inner coil portion of the wound coil to be overlapped and cut, making it impossible to use as a product.

따라서, 파단에 의한 내권부의 풀림현상으로 제품으로서 가치를 상실한 권취코일은 스크랩처리를 하게 되고, 이는 결국 실수율의 하락과 생산성 저하의 원인이 된다.Therefore, the coiling coil which lost its value as a product due to the loosening of the inner winding part due to breakage is scraped, which in turn causes a drop in the error rate and a decrease in productivity.

본 고안은 냉간 압연시 텐션릴에 코일을 권취하는 과정에서 밀스탠드 내부의 코일이 파단되면 권취된 상태의 코일이 장력을 잃고 풀리게 되는데, 이때 누름롤을 이용하여 권취된 코일의 외권부를 신속하게 누름으로써 풀림현상을 미연에 방지하고, 이로써 제품의 생산성과 실수율을 향상시킬 수 있는 권취코일의 내권부 풀림방지장치를 제공함에 그 목적이 있다.In the present invention, if the coil inside the mill stand is broken in the process of winding the coil on the tension reel during cold rolling, the coil in the wound state loses its tension and is released. The purpose of the present invention is to provide an inner ring release preventing device of the coiling coil, which can be prevented in advance by pressing, thereby improving the productivity and the error rate of the product.

도면을 참조하여 본 고안의 구성을 설명한다.The configuration of the present invention will be described with reference to the drawings.

도1은 본 고안에 따른 권취코일의 내권부 풀림방지장치를 나타내는 사시도이고, 도2는 본 고안에 따른 권취코일의 내권부 풀림방지장치의 작업 흐름도이다.Figure 1 is a perspective view showing the inner coil portion loosening prevention device of the winding coil according to the present invention, Figure 2 is a flow chart of the inner coil portion loosening prevention device of the winding coil according to the present invention.

먼저, 한쌍의 지지빔(8)이 텐션릴(15)의 축방향으로 서로 이격되면서 대향되게 설치되어 있고, 내측면 또는 외측면에 각각 유압호스(10)가 연결되어 있는 오일실(oil seal)(9)이 고정되어 있다.First, a pair of support beams 8 are disposed to face each other while being spaced apart from each other in the axial direction of the tension reel 15, and an oil seal in which the hydraulic hoses 10 are connected to inner or outer surfaces, respectively. (9) is fixed.

그리고, 한쌍의 유압실린더(7)는 우측단이 각각 오일실(9)에 결합되면서 좌측단에 각각 유압호스(6)가 연결된 오일실(5)이 설치되어 있고, 중단부에 지지대(12)의 상단이 고정되면서 좌상우하의 경사가 형성되어 있다.In addition, the pair of hydraulic cylinders 7 are coupled to the oil chamber 9 at the right end thereof, and an oil chamber 5 connected to the hydraulic hose 6 at the left end thereof is provided, and the support 12 is disposed at the stop portion. While the upper end of the fixed inclination of the upper left and lower right is formed.

또한, 우측단이 오일실(5)에 각각 내장 결합되는 샤프트(4)는 좌측단에 각각 베어링블록(3)이 결합되면서 이 베어링블록(3)에 코일누름롤(1)의 양단이 각각 결합되어 있다.In addition, the right end is coupled to each of the shaft 4 is built in the oil chamber 5, the bearing block 3 is coupled to the left end, respectively, the both ends of the coil pressing roll 1 is coupled to the bearing block 3, respectively. It is.

한편, 텐션릴(15)과 밀스탠드(20) 사이에 발생되는 스트립(16)의 장력을 감지할 수 있는 장력자동측정제어기(25)(이하 ";AGC:automatic gauging controller";라 함)가 설치되어 있고, 상기 AGC(25)의 신호를 유압밸브(27)에 전달하는 로컬판넬(local panel)(28)이 상기 AGC(25)에 연결되어 있다.Meanwhile, a tension automatic measuring controller 25 (hereinafter referred to as "AGC: automatic gauging controller") capable of detecting the tension of the strip 16 generated between the tension reel 15 and the mill stand 20 is provided. A local panel 28 which is provided and transmits a signal of the AGC 25 to the hydraulic valve 27 is connected to the AGC 25.

여기서, 로컬판넬(28)에 연결되는 유압밸브(27)는 유압펌프(28)의 유압을 전달 받아 유압호스(6,10)에 공급하는 기능을 한다.Here, the hydraulic valve 27 connected to the local panel 28 functions to receive the hydraulic pressure of the hydraulic pump 28 and to supply the hydraulic hoses 6 and 10.

이하, 본 고안의 작용을 설명한다.Hereinafter, the operation of the present invention.

먼저, 권취중인 스트립(16)이 파단되면서 텐션릴(15)과 밀스탠드(20) 사이의 스트립 장력이 제거되면 AGC(25)에서 이를 감지하여 로컬판넬(28)에 신호를 보내게 되고, 로컬판넬(28)의 신호에 의해 유압밸브(27)는 유압펌프(28)의 유압을 유압호스(10)에 공급하게 된다.First, when the strip 16 being wound is broken and the strip tension between the tension reel 15 and the mill stand 20 is removed, the AGC 25 detects this and sends a signal to the local panel 28. By the signal of the panel 28, the hydraulic valve 27 supplies the hydraulic pressure of the hydraulic pump 28 to the hydraulic hose (10).

이때, 유압실린더(27)가 유압호스(10)의 유압에 의해 전진되면서 동시에 샤프트(4)에 의해 코일누름롤(1)이 권취코일(14)의 외권면에 밀착되면서 코일의 권취상태가 유지되도록 누르게 된다.At this time, the hydraulic cylinder 27 is advanced by the hydraulic pressure of the hydraulic hose 10 and at the same time the coil pressing roll 1 is in close contact with the outer circumferential surface of the winding coil 14 by the shaft 4 to maintain the wound state of the coil. Will be pressed.

한편, 권취상태의 풀림이 방지된 코일은 코일카(coil car)로 인출하여 생산한 후 로컬판넬(28)을 오프(off)시키면서 실린더의 샤프트(4)가 후진되면서 코일누름롤(1)이 후퇴하게 된다.On the other hand, the coil is prevented from the unwinding coil is produced by drawing a coil car (coil car) and then the coil pressing roll (1) is rolled back while the shaft (4) of the cylinder is reversed while turning off the local panel (28) You will retreat.

여기서, 로컬판넬(28)은 정상조업중인 경우 항상 온(on)상태에 있고, 스트립(16)이 파단후 코일(14)의 인출시나 라인의 가동전에 오프상태에 있도록 조작한다.Here, the local panel 28 is always in the on state during normal operation, and the strip 16 is operated so that the strip 16 is in the off state when the coil 14 is taken out after breaking or before the line is operated.

본 고안은 냉간 압연시 텐션릴에 코일을 권취하는 과정에서 밀스탠드 내부의 코일이 파단되면 권취된 상태의 코일이 장력을 잃고 풀리게 되는데, 이때 누름롤을 이용하여 권취된 코일의 외권부를 신속하게 누름으로써 풀림현상을 미연에 방지하고 이로써 제품의 생산성과 실수율을 향상시킬 수 있는 효과를 제공한다.In the present invention, if the coil inside the mill stand is broken in the process of winding the coil on the tension reel during cold rolling, the coil in the wound state loses its tension and is released. Press to prevent loosening in advance, thereby improving the productivity and error rate of the product.
