<p>A process for recognising, in a processing cycle performed in sequence in a plurality of separate processing stations, the item to be subjected to the respective processing each time, comprising the following operating steps for each item, to be performed in the first processing station at the latest:
a) application of an identification mark on the surface of the item;
b) association of a dedicated electronic memory with the identification mark;
c) saving of the physical characteristics of the item already known in advance, if they exist, in the electronic memory dedicated to the identification mark. According to the invention the process also comprises, in the first processing station and for each item to be processed, the following additional operating step d): the image of the identification mark on the surface of the item is detected and this image is electronically saved in the electronic memory dedicated to this identification mark, and subsequently in each processing station after the first and for each item to be processed, the process comprises the following additional operating steps: e) before the item is fed into the processing station the image of the identification mark on the surface of the item is detected; f) the image detected during the previous operating step e) is compared with all of the images saved in the various electronic memories dedicated to the various identification marks and the one which most closely resembles the image detected in the previous operating step e) is identified; g) the identification mark associated with the image saved that was identified in the previous operating step f) is identified; h) all of the characteristics saved in the electronic memory dedicated to the identification mark identified in the previous step g) are assigned to the item about to enter the processing station;
i) the processing to be performed on the item in the processing station is adapted to the physical characteristics assigned to the item in the previous operating step h).</p> |
