Method for recording machining information associated with insulating panels manufactured in a continuous machining line and relative system

A method for recording machining information associated with insulating panels manufactured in a continuous machining line,

• said continuous machining line comprising one or more machining units adapted to carry out machining operations on a panel body moved along a machining direction between an inlet and an outlet of the continuous machining line, said panel body being fed from a start-production unit arranged at the inlet of the machining line and said insulating panels being manufactured by making cuts in the panel body, according to a predetermined measurement, at the outlet of the continuous machining line, each of said one or more machining units being controlled by a respective electronic control unit of the machining operations carried out,
• the method comprising the steps of:
• generating, by a first electronic control unit, a plurality of unique graphic representation identification codes, each of the unique graphic representation identification codes of the plurality identifying a portion of the panel body to be machined;
• printing, through a peripheral printing unit controlled by the first electronic control unit, said unique graphic representation identification codes on an outer surface of the panel body at the outlet of the start-production unit during the continuous manufacturing process, each new unique graphic representation identification code being printed on the panel body portion to be machined identified thereby after the panel body has been moved by a predetermined distance, so that the new unique graphic representation identification code and the previously printed unique graphic representation identification code are separated from each other by said predetermined distance;
• detecting in succession, by at least one of said electronic control units, the unique graphic representation identification codes printed on the outer surface of the panel body to be machined, when the panel body portions identified by each of said unique graphic representation identification codes pass through the at least one machining unit controlled by the at least one of said electronic control units;
• acquiring, by the at least one of said electronic control units, information of machining operations carried out on the panel body portion identified by the detected unique graphic representation identification code;
• associating said acquired machining information with the detected unique graphic representation identification code;
• sending, by the at least one of said electronic control units, said acquired machining information and the unique graphic representation identification code associated therewith to a main processing unit connected with the at least one electronic control unit;
• storing said acquired machining information and the unique graphic representation identification code associated with said acquired machining information in a memory of said main processing unit;
• storing in said memory of the main processing unit a unique identification number of the insulating panel portion configured to encode, with a numerical string, at least a distance indication of the panel portion relative to an edge of the panel;
• wherein the unique identification number is associated in the memory with the graphic representation identification codes associated with said insulating panel portion.
