Method and machine for automatic assembly of complex cages formed from electro-welded metal nets

Machinery for automatic assembly of a complex three-dimensional reticular structure, formed by electro-welded metal nets, comprising:

• a bidirectional horizontal folding assembly for electro-welded metal nets, positioned transversally with respect to a flow of advancement of the electro-welded metal nets;
• a first horizontal trolley, arranged upstream of the folding assembly and parallel to the folding assembly, which is provided with automatic grippers to grip, to transport the electro-welded metal nets;
• a second horizontal trolley, arranged downstream of the folding assembly and parallel to the folding assembly, which is provided with automatic grippers to grip, to transport the electro-welded metal nets;
• a zone of horizontal parking or pre-assembly for at least one cage, which is located downstream of the second horizontal trolley;
• a zone further downstream than the zone of horizontal parking or pre-assembly, to evacuate finished products;
• and
• a plurality of movable assemblies, which are overhead, movable along a level, and supported by guides and a frame, and which are provided with automatic grippers to grip metal nets or cages to serve the movable assemblies, and
• whereby the machinery is configured to lift at least one pre-assembled cage using the automatic grippers of the movable assemblies from a sliding plane of an electro-welded metal net from which an external cage is to be folded, to allow folding of the external enclosure cage and a definite closure thereof, to partially fold the external enclosure cage, to insert the lifted pre-assembled cage that will become an internal cage into the partially folded external enclosure cage, and to close the partially folded external enclosure cage.
