Patent ID: 7971511

Claim:
A panel saw machine comprising: a horizontal work table ( 3 ) for movably supporting panels ( 2 ) for movement at least along an axis of feed (X) in a forward direction (V 1 ) and in a backward direction (V 2 ); a clamping unit ( 4 ) comprising a crossbar ( 5 ) equipped with one or more gripping elements ( 6 ) for clamping and retaining at least one panel ( 2 ) at least while the panel ( 2 ) is being cut; a cutting unit ( 7 ) that divides the at least one panel ( 2 ) into sub-panels by sawing the panel ( 2 ) along an axis (Y) that is substantially transverse to the feed axis (X); a horizontal tray ( 8 ) supported on and movable relative to the horizontal work table ( 3 ), said tray supporting and transporting the at least one panel ( 2 ); holding means ( 9 ) for selectively holding the tray ( 8 ), said holding means comprising at least three carriages, each of said carriages being located adjacent the work table and movable relative to the work table; driving means ( 10 ) for selectively driving the holding means relative to the work table; said holding means and said driving means selectively acting together to perform a first movement of the tray relative to the work table along the feed axis (X) in the forward and backward directions (V 1 , V 2 ) and to perform a rotational movement (R) of the tray ( 8 ) relative to the work table ( 3 ) in such a way as to vary the position of the tray ( 8 ) and, consequently, of the at least one panel ( 2 ), with respect to the cutting unit ( 7 ), wherein a first plurality of said carriages of said holding means selectively engage the tray in a first holding configuration and said driving means selectively act on and move the first plurality of carriages relative to the work table in order to move the tray in the forward and backward directions relative to the work table; and, wherein a second plurality of said carriages of said holding means engage the tray in a second holding configuration that is different from said first holding configuration and said driving means selectively act on and move the second plurality of carriages relative to the work table to rotate the tray relative to the work table.
