Method for marking references on a flat article and a system actuating the method

A system for actuating a method for marking reference signs on a flat article, wherein the method comprises:

• providing a flat article to be marked, the flat article to be marked having a peripheral profile;
• a) predisposing, on a detecting plane, a model having a peripheral profile and provided with at least one through-opening, the peripheral profile of the model being the same as and corresponding to the peripheral profile of the flat article to be marked;
• b) detecting the peripheral profile of the model with respect to a reference system and storing the peripheral profile of the model in a memory of a processing device;
• c) detecting a profile of the at least one through-opening and the relative positioning thereof with respect to a reference system;
• d) predisposing the flat article to be marked on a marking plane;
• e) detecting the peripheral profile of the flat article predisposed on the marking plane;
• f) replicating on the marking plane wherein the article to be marked is predisposed the detected peripheral profile of the model in such a way as to superpose the peripheral profile of the model on the peripheral profile of the flat article;
• g) replicating on the marking plane also the detected profile of the at least one through-opening of the model, taking account of the relative positioning with respect to a reference system and taking account of the positioning of the peripheral profile of the model with respect to the peripheral profile of the flat article;
• h) contactlessly marking at least one reference sign on the flat article at the profile of the at least one through-opening which has been replicated
• the system comprising:
• a detecting plane, for restingly receiving a model provided with at least a through-opening;
• a first digital uploading system of images for detecting the peripheral profile of the model of the profile of the through-opening;
• a marking plane for restingly receiving a flat article to be marked;
• a second digital uploading system of images, for detecting the peripheral profile of the flat article to be marked;
• a processing device, comprising in turn a memory, for storing the peripheral profile of the model and the profile of the through-opening detected on the detecting plane, and for replicating the peripheral profile of the model and the profile of the relative opening on the marking plane, in such a way that the peripheral profile of the model is superposed on the peripheral profile of the flat article to be marked and for managing the whole marking operation;
• contactless marking means for marking at least a reference on the flat article at the opening profile of the model.
