Machine for the laser working of tubes and profiles, in particular machine for the laser cutting of tubes and profiles, with an improved unloading system for unloading the tube or profile at the end of the working process

A machine for laser working of tubes and profiles, comprising

• a working unit provided with a laser working head,
• a feeding device arranged to move each time a tube or profile to be worked towards the working unit along a feed axis,
• an unloading system for unloading the tube or profile at the end of the working process, said unloading system comprising one or more supporting and unloading devices arranged along the feed axis of the machine and below said axis, wherein each supporting and unloading device comprises a table and a driving unit associated with the table, and
• a control unit,
• wherein the table of each supporting and unloading device comprises a first table portion having an upper surface, and a second table portion extending laterally outwards relative to the first table portion and having an upper surface,
• wherein said driving unit is configured to produce a roto-translational movement of the table of each supporting and unloading device, with a vertical translation and a rotation about a horizontal axis of rotation, oriented parallel to the feed axis of the machine, between a working position, in which the upper surface of the first table portion is oriented so as to support the tube or profile being worked, and in which the upper surface of the second table portion is oriented so that an outer longitudinal edge of said upper surface is placed at a height greater than that of an inner longitudinal edge of said upper surface, and an unloading position, in which the table is shifted vertically and rotated about said axis of rotation relative to said working position, in such a manner that an outer longitudinal edge of the upper surface of the first table portion is placed at a height lower than that of an inner longitudinal edge of said upper surface, and the outer longitudinal edge of the upper surface of the second table portion is placed at a height lower than or equal to that of the inner longitudinal edge of said upper surface, and
• wherein said control unit is programmed to control the driving unit of each supporting and unloading device so as to move the table from said working position to said unloading position and vice versa.
