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

An automatic machine for drilling and milling substantially flat glass sheets arranged vertically or almost vertically, having a rectangular or other than rectangular shape, comprising:

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