Depalletization device that disassembles a pallet composed of at least a number of layers, comprising: • A loading/unloading device that separates and extracts said layer from said pallet; and • A first conveyor fed by said loading/unloading device with said layer separated from said pallet and moves said layer forward; • A second conveyor fed by said first conveyor with the entire above-mentioned layer; • A pair of third conveyors (11a, 11b) that receives, one or the other alternatingly, the entire said layer; and • Actuator means controlled to transfer the entire said layer from said second conveyor alternatingly onto one or the other of said third conveyors (11a, 11b), characterized by the fact, that said actuator means is configured to move parallel to a first axis alternatingly or into a first line to move the entire said layer and transfer said layer onto one of said third conveyors (11a, 11b) or into a second line, which points in the opposite direction from the first line, to move the entire said layer and transfer said layer onto the other of said third conveyors (11a, 11b), and by the fact that said second conveyor is configured to move parallel to a second axis that is transverse to said first axis, and in that it comprises a control device that is programmed to: • move said second conveyor parallel to said second axis in such a way as to transfer the entire above-mentioned layer onto the above-mentioned second conveyor and to place said layer in the desired position on said conveyor and at the same time to keep the above-mentioned actuator means halted parallel to said first axis in a position in which said actuator means are, when in use, separated from said layer; and • halt said second conveyor and at the same time move said actuator means parallel to said first axis once the transfer and positioning of the entire above-mentioned layer on said second conveyor have been completed in such a way as to transfer the entire above-mentioned layer onto one or the other of said third conveyors (11a, 11b) alternatingly. • A loading/unloading device that separates and extracts said layer from said pallet; and • A first conveyor fed by said loading/unloading device with said layer separated from said pallet and moves said layer forward; • A second conveyor fed by said first conveyor with the entire above-mentioned layer; • A second conveyor fed by said first conveyor with the entire above-mentioned layer; • A pair of third conveyors (11a, 11b) that receives, one or the other alternatingly, the entire said layer; and • Actuator means controlled to transfer the entire said layer from said second conveyor alternatingly onto one or the other of said third conveyors (11a, 11b), characterized by the fact, that said actuator means is configured to move parallel to a first axis alternatingly or into a first line to move the entire said layer and transfer said layer onto one of said third conveyors (11a, 11b) or into a second line, which points in the opposite direction from the first line, to move the entire said layer and transfer said layer onto the other of said third conveyors (11a, 11b), • move said second conveyor parallel to said second axis in such a way as to transfer the entire above-mentioned layer onto the above-mentioned second conveyor and to place said layer in the desired position on said conveyor and at the same time to keep the above-mentioned actuator means halted parallel to said first axis in a position in which said actuator means are, when in use, separated from said layer; and • halt said second conveyor and at the same time move said actuator means parallel to said first axis once the transfer and positioning of the entire above-mentioned layer on said second conveyor have been completed in such a way as to transfer the entire above-mentioned layer onto one or the other of said third conveyors (11a, 11b) alternatingly.
