Abstract

This method relates to the inspection of pharmaceutical filled capsules. The object of this inspection method is to detect mainly structural defects of the capsule with or without printing. To recognize the characters which are printed on the surface of the capsule is not an object. Capsules consist of a cap and body which are telescopically fitted together, and the bodies are filled with medicinal material. The two spherical ends and near the center region of each capsule should be inspected for defects. Further the area where printing may cover should be inspected for indications of such defects as a foreign material, a body dent or a speck. On the basis of projection technique, the body/cap boundary points can be distinguished from the printing edge points near the body/cap boundary, and the size of the area which the printing may cover can also be computed.
