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 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 identification code and the previously printed identification code are separated from each other by said predetermined distance;
• detecting in succession, by at least one of said electronic control units, the 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 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 to be stored in a memory of said main processing unit;
• associating with each insulating panel manufactured at the outlet of the continuous machining line a unique identification number of the panel configured to encode, with a numerical string, one or more graphic representation identification codes associated with said insulating panel;
• sending said unique identification number of the panel to said main processing unit to be stored in said memory.
