본 고안은 냉간압연라인에서 생산되는 냉연코일의 표면형상을 검출하는 검출계를 청소하는 장치에 관한 것으로, 보다 상세히는, 단시간내에 손쉽게 검출면의 이물질과, 먼지등을 소제하여 작업생산성을 향상시키고, 냉연코일의 품질을 향상시킬 수 있도록한 형상검출계 청소장치에 관한 것이다.The present invention relates to a device for cleaning the detection system for detecting the surface shape of the cold rolled coil produced in the cold rolling line, more specifically, to improve the work productivity by cleaning the foreign matter and dust on the detection surface easily within a short time The present invention relates to a shape detection system cleaning device capable of improving the quality of a cold rolled coil.
일반적으로 철판을 냉간압연시에는 냉각작용, 윤활작용과 압연성을 좋게하기 위하여 압연유(우지)를 분사하게되는데 분사된 압연유와 먼지 이물질등의 철판을 타고 함께 흘러 형상계 검출면에 부착되여 항상 검출이 불량하고 부착된 압연유는 우지성분으로 부착성이 강하여 쉽게 세척이 되지 않아 설비 자동운전이 불가능하여 수동운전으로 철판의 형상을 육안 체크하면서 작업을 하며 검출면에 부착된 압연유를 제거하기 위해 작업자가 손으로 닦아야하는 많은 문제점을 갖고 있다.In general, during cold rolling of the steel sheet, rolling oil (uji) is sprayed to improve cooling, lubrication, and rolling properties. This poor and adhered rolled oil has strong adhesiveness, so it is not easily cleaned, so it is not possible to automatically operate the equipment. Therefore, the operator checks the shape of the steel plate by manual operation. There are many problems that need to be cleaned by hand.
이와같은 형상검출불량을 방지하기위한 종래의 형상검출계 청소장치(100)가 제4도에 도시되어 있다. 상기 형상검출계 청소장치(100)는 검출계(110)의 전, 후면에 더운물 분사노즐(120)과 공기분사노즐(130)이 설치되어 검출계(110)의 표면에 부착되는 압연유와 이물질 및 먼지등을 더운물과 공기로서 제기하도록 되어있다. 그러나 이러한 장치로서는 압연유의 부착성이 매우강하기 때문에 효과적으로 이물질 및 먼지등을 제거할 수 없기 때문에 작업자는 수시로 검출계(100)의 검출면(110a)을 걸레등으로 닦고 있는 실정이었다. 따라서 청소작업시간이 오래걸리고, 작업자의 일량이 증가하기 때문에 작업생산성을 저하되는 것이며, 전체적으로 검출면(110a)의 청소상태가 불량하여 검출계(110)의 오동작이 빈발하기 때문에 냉연코일의 품질이 저하되는 것이었다.A conventional shape detection system cleaning apparatus 100 for preventing such shape detection failure is shown in FIG. The shape detection system cleaning device 100 is a hot water spray nozzle 120 and the air spray nozzle 130 is installed on the front, rear of the detection system 110 and the rolling oil and foreign matter attached to the surface of the detection system 110 and It is supposed to raise dust as hot water and air. However, in such a device, since the adhesion of the rolling oil is very strong, foreign matters and dust cannot be effectively removed, so that the worker frequently wipes the detection surface 110a of the detection system 100 with a rag or the like. Therefore, the cleaning operation takes a long time, and the work productivity increases because of the increase of the worker's work, and the overall quality of the cold rolled coil is poor because the malfunction of the detection system 110 is frequent due to the poor cleaning state of the detection surface 110a. It was to be degraded.
본 고안은 상기와 같은 문제점을 해소하기 위하여 안출된 것으로서, 단시간내에 검출면에 부착된 압연유와 이물질 및 먼지등을 손쉽게 소제하여 작업생산성을 향상시키고, 형상검출의 오동작을 방지하여 냉연코일의 품질을 향상시킬 수 있도록한 형상검출계 청소장치를 제공함에 그 목적이 있다.The present invention has been devised to solve the above problems, and can easily clean the rolling oil, foreign substances and dust attached to the detection surface within a short time to improve the work productivity, and prevent the malfunction of shape detection to improve the quality of the cold rolled coil. It is an object of the present invention to provide a shape detection system cleaning device that can be improved.

At this time, when the rolling oil sprayed during the cold rolling operation flows along the steel plate and adheres to the detection surface 11a of the detection system 110, the detection system 110 is finished in the state where the work of the cold rolling coil currently being worked is finished. Carry out a sweep. At this time, the air pressure control unit 15 is operated to discharge the air from the air pressure cylinders 12a and 12b to lower the detection system 110 by a certain height. Then, by operating the hot water control unit 35 to spray hot water through the hot water injection nozzle 32 to the upper surface of the detection system 110, to operate the pinion drive motor 66 and the brush drive motor 64. Operate the power supply terminal box. As the pinion drive motor 66 is rotated forward, the pinion gear 66b connected to the rotating shaft is advanced along the rack member 59 of the body portion 55, which moves the brush mount 57 to the body portion 55. Advanced on). At this time, a sliding motion is generated between the rails 58a and 58b formed in the body part 55 and the grooves 62a and 62b of the brush mount 57. In addition, as the brush drive motor 64 is operated, the sprocket 64b formed on the rotating shaft is rotated, the sprocket 78 of the support rod 72 is rotated through the chain C 1 , and the detection system 110 of the detection system 110 is rotated. The hair brush 74 is in contact with the upper surface (detection surface) to rotate and remove the rolling oil, foreign matter and dust. When the brush mount 57 is moved to the front end of the body portion 55, the pinion drive motor 66 is reversely rotated in the opposite direction to the above, and the pinion gear 66b is also reversely rotated so that the rack member Will retreat along 59. However, the brush drive motor 64 is to continue to rotate in the same direction to remove the rolling oil, foreign matter and dust while the brush mount 57 is reversed along the detection surface (110a). As described above, while the brush mount 57 moves backward along the detection surface 110a, rolling oil, foreign matter, and dust are removed. The hot water spray nozzle 32 of the hot water spraying device 30 is again in the state where the brush mount 57 reciprocates along the detection system 110 and removes the rolled oil, foreign matter, and dust from the detection surface 110a as described above. The hot water is sprayed on the detection surface (110a) by cleaning again to complete the cleaning operation. Therefore, when the cleaning process is completed, air is supplied to the pneumatic cylinders 12a and 12b again to raise the detection system 110 to perform the shape detection operation of the cold rolled coil S.
상기에서와 같이 본 고안에 의하면, 브러쉬장착대(57)가 몸체부(55)의 상부에서 검출계(110)의 검출면(110a)을 길이방향으로 이동하면서 소제시키기 때문에, 별도의 청소원이 필요없게되고, 소제시간도 단축되어, 작업생산성이 크게 개선된다. 또한, 검출계(110)의 청소상태가 현저히 개선되어 압연유, 이물질 및 먼지등이 효과적으로 제거되기 때문에 형상검출의 오동작이 발생되지 않고 따라서 냉연코일의 품질향상이 이루어지게 되는 실용상의 효과가 얻어지는 것이다.According to the present invention as described above, since the brush mounting stand 57 to clean the detection surface 110a of the detection system 110 in the longitudinal direction at the upper portion of the body portion 55, a separate cleaning source is required The cleaning time is also shortened, and the work productivity is greatly improved. In addition, since the cleaning state of the detection system 110 is remarkably improved, rolling oil, foreign matter, dust, and the like are effectively removed, so that malfunction of shape detection does not occur, and thus the practical effect of improving the quality of the cold rolled coil is achieved.
