Abstract
Apparatus for detecting checks in the finish of a translucent container that includes a first optical subassembly in which a first light source directs light energy onto the container finish as it rotates and a first light sensor receives portions of the first light energy reflected from horizontal checks in the container finish, and second and third optical subassemblies include respective second and third light sources and associated second and third sensors for directing light energy onto the container finish and receiving energy reflected from vertical checks in the container finish. Each optical subassembly includes an associated mounting plate, by means of which the optical subassemblies are mounted at an inspection station with the first light source and sensor disposed in a vertical plane, and the second and third light sources and sensors disposed in opposed mirror-image arrays on opposite sides of the vertical plane. The mounting plates include interlocking pins and slots that are configured for simultaneous adjustment of all optical subassemblies to accommodate container finishes of differing diameter.
