Automatic machine and method for automatically drilling and milling glass sheets arranged vertically

An automatic machine for drilling and milling a substantially flat glass sheet, having a rectangular or other than rectangular shape, the machine comprising:

• a machine body;
• an input conveyor provided with a motorized roller conveyor or a roller belt and adapted to convey the glass sheet by means of a lower edge thereof,
• an input conveyance surface provided with idle gliding wheels;
• an output conveyor provided with a motorized roller conveyor or a motorized belt and adapted to convey the glass sheet by means of said lower edge;
• an output conveyance surface provided with idle gliding wheels;
• a first carriage provided with a horizontal motion along a longitudinal axis X2;
• at least one pair of working heads, each of the working heads being provided so as to be independently movable for adjustment and feeding in a respective one of two axes Y1 and Y2 having a vertical component, each head bearing a respective tool provided with rotary cutting motion, and each of the tools being provided with a respective feeding motion along a respective one of axes Z1 and Z2 that are perpendicular to a face of the glass sheet,
• wherein at least one of the tools is adapted to make contact with a surface and therefore with a body of said glass sheet,
• wherein one of the two heads is also provided with a second carriage that performs a feeding motion along a longitudinal axis X1 while the other of the two heads is provided with at least one sucker that engages the surface of the glass sheet during processes performed by said one head or the opposite head or by the two heads simultaneously.
