Panel sawing device

A device for sawing stacks of panels comprising:

• a table to support a stack of panels having a preset height and an upper free surface;
• means for pressing down on a portion of the stack of panels and which can move vertically in both directions, said pressing means adapted for immovably securing the stack of panels on said table when said stack of panels is cut;
• a gripper and handling unit designed to pick up the stack of panels and feed it on the table along a horizontal feed axis towards a part of the table where said means for pressing down on a portion of the stack of panels are located;
• means for cutting the stack, when the stack is immovably secured by said pressing means, said cutting means driven in first and second opposite directions along an axis transverse to the feed axis in such a way as to perform a cutting stroke to make a cut in the stack to a defined cutting depth in the first direction and an idle return stroke in the second direction, said cutting means comprising:
• (i) a first carriage that mounts a first circular saw blade and a first circular scoring saw for the stack, said first scoring saw located relative to the first circular saw blade and relative to the first direction so that said first scoring saw comes into contact with the stack before the first circular saw blade does, and, (ii) a second carriage that mounts a second circular saw blade and a second circular scoring saw and that is located opposite the first carriage on an opposite side of the stack of panels relative to the first carriage, the second carriage moving in the first and second directions along the transverse axis in synchrony with the first carriage, wherein said first and second circular saw blades are aligned with each other in a vertical plane and make respective first and second cuts in the stack to respective first and second defined cutting depths in such a way as to make a complete cut through the stack of panels.
