Installation for the laser marking of the surface of a cheese or delicatessen food product

An installation for marking the surface of a cheese or a meat product, which comprises a laser, means for supporting the food product to be marked, means capable of obtaining a transverse sweep, combined with a relative longitudinal sliding, of the laser beam in relation to said supporting means, and a removable mask intended to be interposed in the path of said laser beam and having apertures, the edges of which correspond to the contours of the mark to be made, characterized in that it has at least one marking station, comprising:

• a horizontal linear table supporting a carriage mounted horizontally slidably along an axis xx;
• means for receiving said laser beam coming from said laser and for reflecting said beam along said axis xx in the front direction, forming a laser-beam projection assembly;
• a first reflector device for reflecting said laser beam vertically downwards, carried frontally by said carriage on said axis xx, so as to receive said laser beam exiting from said projection assembly;
• a second reflector device for reflecting said laser beam, on the one hand along an axis x'x' parallel to and located vertically below and in line with said axis xx, and on the other hand the front direction, arranged proximally and frontally in relation to said table;
• a horizontal tray for supporting said food product to be marked, mounted pivotably about a vertical axis located substantially in the mid-plane xxx'x', located distally and frontally in relation to said table and substantially coplanar with the second reflector device;
• means for driving the supporting tray to pivot about its axis;
• means for driving said carriage to slide along said sliding axis xx between a distal position and a proximal position where said first reflector device is located vertically above and in line with said supporting tray and with said second reflector device respectively;
• means of controlling the means for driving said tray and the means for driving said carriage to slide along said axis xx.
