Title (EN) METHOD FOR MEASURING QUALITY OF BANDLIKE BODY, METHOD FOR SUPPRESSING CAMBER, INSTRUMENT FOR MEASURING QUALITY OF BANDLIKE BODY, ROLLING MACHINE, AND TRIMMING DEVICE
(FR) PROCEDE POUR MESURER LA QUALITE D'UN CORPS EN FORME DE BANDE, PROCEDE DE SUPPRESSION DE LA CAMBRURE, INSTRUMENT POUR MESURER LA QUALITE D'UN CORPS EN FORME DE BANDE, MACHINE DE LAMINAGE ET DISPOSITIF DE ROGNAGE
Abstract:
(EN) A bandlike body being conveyed by a roller is imaged by e.g. a television camera. The distances from positions along an edge of the imaged bandlike body to a reference line provided in the longitudinal direction of the bandlike body are measured, the camber and meander of the bandlike body are determined from the distance of the same position, and the width of the bandlike body is determined from the distances of a pair of positions along the same line in the lateral direction of the bandlike body. A defect, if any, on the surface of the bandlike body is detected on the basis of the luminance of a pixel in the image. A chipping, if any, along the edges is detected on the basis of the distances. The rolling machine and trimming device of the bandlike body are subjected to feedfoward control on the basis of the camber, meander and width.
(FR) Un corps en forme de bande transporté par un rouleau de laminage est représenté en images par exemple par une caméra de télévision. Les distances entre des positions situées le long d'un bord du corps en forme de bande ainsi représenté et une ligne de références située dans le sens longitudinal du corps en forme de bande sont mesurées, la cambrure et la sinuosité du corps en forme de bande sont déterminées à partir de la distance de cette même position, et la largeur de ce corps en forme de bande est déterminée à partir des distances d'une paire de positions le long de cette même ligne dans le sens latéral du corps en forme de bande. Un défaut, situé le cas échéant sur la surface du corps en forme de bande, est détecté sur la base de la luminance d'un pixel compris dans l'image. Un écaillage, se produisant le cas échéant le long des bords du corps en forme de bande, est détecté sur la base de ces distances. La machine de laminage et le dispositif de rognage de ce corps en forme de bande sont soumis à une commande d'avance sur la base de la cambrure, de la sinuosité et de la largeur du corps en forme de bande ainsi mesuré.
