Abstract:
Device for separating, lifting and transporting sheets of aluminium or other non-ferromagnetic material consisting of a spider attraction assembly (8) and an electrical supply system (9), characterised in that the spider attraction assembly (8) is a rectangular metal housing, made of any non-ferromagnetic material, with dimensions similar to those of the sheets of aluminium (2) to be manipulated, having a series of blocks of magnets (10) arranged linearly along the two longer sides of the rectangle forming said housing; said spider assembly being provided, at the beginning and end of the row of blocks of magnets (10), with two cylindrical metal retractable electrodes (11) that end in a flat, square surface (12) of 30 to 50 mm. sides in order to improve the transmission of the electrical current, connected to the electrical supply system (9) by way of electrical conductors (18), said spider assembly being provided with the capacity to attract sheets of aluminium when an electrical current is made to circulate in the surroundings of the edge (1) of a sheet (2) of aluminium while at the same time the edge (1) is under the action of a magnetic field, since said sheet is attracted by a force-field (7) when an electrical current is made to circulate through its edges (1) while at the same time said edges (1) are under the action of a magnetic field.
