Abstract
An automatic device for determining print quality on bottles of circular, elliptical or polygonal cross-section, comprising at least one print quality inspection station in which a cylindrical portion of the image surface is photographed by a camera or video camera, means for transferring the object to successive inspection stations in succession, in each of which a further portion of the image is photographed, means for assembling the images acquired in each inspection station to obtain the overall image of all the photographed portions, comparator means for comparing the overall image with a reference image, and means for indicating non-conformity between the overall acquired image and the reference image and for operating an actuator which feeds the object carrying the non-conforming overall image to a rejected object collection line, in which a single inspection station comprises means for rotating the image-carrying object through an angle of at least 360.degree. with continuity, one video camera arranged to photograph in succession an image portion after each rotation of the bottle through an angle equal to 360.degree. divided by the total number of images to be acquired, means for assembling the acquired images to obtain the overall image of all the portions photographed, and comparator means for comparing the overall image with a reference image.
