US 2012/0222285 A1 · METHOD AND MACHINE FOR AUTOMATIC ASSEMBLY OF COMPLEX CAGES FORMED FROM ELECTRO-WELDED METAL NETS

Abstract

The present invention relates to a method and the associated machine for the automatic production and assembly of complex reticular cages, formed by simple cages, contained and encircled by an ultimate external enclosure cage or net. The automatic machine that carries out the aforementioned method in reality consists of a group of various machines and mechanical devices which are coordinated by suitable computerised systems, which comprise: a folding assembly (3) for electro-welded metal nets which is served by two automatic movable trolleys, one upstream (2) and the other downstream (6), for positioning the nets during the programmed folding phases; a temporary parking zone (41) or pre-assembly zone for the simple cages, downstream, with a subsequent final evacuation path (42); overhead there is a plurality of automatically movable trolleys (44) which are equipped with suitable automatic grippers (5) for transporting and positioning the simple and/or complex cages.

A method for the automatic and continuous construction and assembly of a complex three-dimensional reticular structure derived from electro-welded metal nets that can be used as reinforcements in concrete castings in anti-seismic construction projects, the method comprising the steps:

pre-assembling at least one cage in a zone located downstream of a folding assembly so as to allow its continuous construction;
transporting the at least one pre-assembled cage to the folding assembly for the formation of an external enclosure cage;
lifting the at least one pre-assembled cage using automatic grippers from a sliding plane of an electro-welded metal net from which the external enclosure cage is to be folded, to allow the folding of the external enclosure cage and the definite closure thereof, thus encircling the at least one pre-assembled cage and forming the complex three-dimensional reticular structure.

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 net;
a horizontal trolley, arranged upstream of the folding assembly and parallel to it, which is provided with automatic grippers for gripping, for the transport of the electro-welded metal nets;
a horizontal trolley, arranged downstream of the folding assembly and parallel to it, which is provided with automatic grippers for gripping, for the transport of the electro-welded metal nets;
a zone for horizontal parking or pre-assembly of at least one cage, which is located downstream of the trolley;
a zone further downstream than the zone for horizontal parking or pre-assembly, for evacuation of the finished products;
a plurality of movable assemblies, which are overhead, movable along the level, and supported by guides and a frame, and which are provided with the automatic grippers for gripping metal nets or cages to serve the aforementioned assemblies.
