ABSTRACT:
The invention refers to an apparatus of the type for automatic identification and registration of bottles of different sizes and/or shapes advanced one after the other along a path, at least some bottles having glass of a high light transparency. The bottles pass through the ray path of a light source-photocell arrangement forming a detector unit. According to the invention, the detector unit comprises a matrix having a universally and systematically grouped array of photo cells in the side and height directions of the bottles, each of said photo cells being actuable by a different and directed light ray from a point-shaped light source, and being, by means of a programming unit, programmable to respond in predetermined patterns, corresponding to the bottle types to be identified, a plurality of detecting operations being performed at points determined by the matrix while a bottle is advanced a certain distance.
