Abstract

본 발명은 쌍롤식 박판 제조장치용 롤갭 측정장치 및 측정방법에 관한 것으로 비접촉식 센서를 이용하여 자동 롤갭제어 프로세서로서 롤갭을 자동으로 제어함은 물론, 롤척갭에 의한 간접적인 롤갭 측정보다 롤갭의 측정 정확도가 우수하게 되는 한편, 온도상승에 따른 롤 팽창 계수를 직접 자동롤갭장치에 포함시키게 되어 롤갭 측정장치의 정밀도를 극대화하는데 그 목적이 있다.The present invention relates to a roll gap measuring device and a measuring method for a double roll sheet metal manufacturing apparatus, which automatically controls the roll gap as an automatic roll gap control processor using a non-contact sensor, as well as measuring accuracy of the roll gap rather than indirect roll gap measurement by the roll chuck gap. On the other hand, the roll expansion coefficient according to the temperature rise is directly included in the automatic roll gap device, the purpose is to maximize the precision of the roll gap measuring device.

상기와 같은 목적을 달성하기 위하여 본 발명은, 비고정식 롤(2')의 수평 및 수직 움직임을 비접촉식 센서(12,12',15.15')로서 측정하여, 이 측정된 데이터는 자동롤 갭 제어프로세서(7)로서 실제 롤갭(9)으로 환산되고,비접촉식 센서(13,13')로서 롤의 부피변동에 따른 상기 롤갭(9)의 변화를 측정하는 구성으로 이루어지는 데에 그 요지가 있다.In order to achieve the above object, the present invention measures the horizontal and vertical movement of the non-fixed roll 2 'as the non-contact sensors 12, 12' and 15.15 'so that the measured data is automatically roll gap control processor. The point is made into the structure which is converted into the actual roll gap 9 as (7), and measures the change of the said roll gap 9 according to the volume change of a roll as the non-contact sensors 13 and 13 '.
