METHOD FOR DETECTING ISSUES WITH COIL EYES AND A COIL EYE DIAMETER MEASUREMENT CAMERA SYSTEM THEREFOR

摘要

A method for detecting steel coils having a misshapen coil eye and removing these coils from a production queue. The method comprises providing a queue of steel coils, which may be being conveyed on a coil conveying system. Each coil having a coil eye. Providing a camera and light source for the camera. Providing a retroreflector to reflect light from said light source. The method includes the step of passing each coil between the camera/light source and the retroreflector. The light source is strobed, and light passes through the coil eye and is reflected back to the camera. The camera records a saturated image of the coil eye. The image is used to analyze the min/max diameters of the coil eye and coils with misshapen eyes may be rejected.
