Large field-of-view gauging on paper rolls
Cognex enables Norske Skog to meet significant control challenges by changing from manual to automated inspection with the aid of a system designed by ControlVision. Prior to the development of the system, excessive eccentricity was causing vibration and web breaks on customer’s printing presses, and operators were manually measuring paper rolls, looking for ones that were off center. This process was both unreliable and time-consuming. VisionProTM vision software was implemented to perform image calibration, pattern-matching, and edge-finding. These functions ensure that the paper rolls are balanced and centered properly. Norske Skog was able to have this dependable and timely system installed without any customized software.
