Abstract
A plant for applying and welding stiffeners onto a plate is disclosed. The plant includes a welding station, a buffer station and a carriage movable between the buffer station and the welding station, the carriage being suspended in a cantilever beam extending over said stations. The carriage collects stiffeners in the buffer station and transports said stiffeners onto the plate in the welding station, means being provided to press said stiffeners to be welded against the plate. Welding means are arranged at one end of the carriage, the welding process taking place while the carriage returns to the buffer station to collect new stiffeners.
Claims16
A method for welding elongate reinforcing elements to a metal plate comprising the steps of holding said metal plate to lie in a substantially horizontal plane at a welding station, positioning at least one reinforcing element at a buffer station generally located adjacent said welding station, reciprocally moving a carriage along a generally linear path between said welding station and said buffer station, said carriage having mounted thereon welding means and means for releasably gripping said reinforcing elements, moving said carriage from said buffer station to said welding station to transport to said welding station into welding positions reinforcing elements gripped by said gripping means of said carriage at said buffer station, pressing against said plate and simultaneously welding to said plate the reinforcing elements positioned at said welding station by operation of said welding means while moving said carriage from said welding station to said buffer station and simultaneously causing said gripping means to engage reinforcing elements positioned at said buffer station, and returning said carriage to said welding station to move thereto into welding position subsequent reinforcing elements to be welded.
Apparatus for applying and welding elongate reinforcing elements onto metal plates, said apparatus comprising a welding station in which the plate is held in a substantially horizontal position, a buffer station for reinforcing elements located adjacent said welding station, a carriage movable from said buffer station in over said plate in said welding station to place at least one reinforcing element collected in said buffer station onto said plate, a cantilever beam extending over said buffer station and said welding station, said carriage being movable in over the plate in the welding station while carried by said cantilever beam, means for pressing against said plate during the welding process each element placed on said plate by said carriage, and welding means arranged to be displaced along the elements thus pressed to said plate in order to simultaneously weld said element to said plate, said welding means being located at one end of said carriage so that they are displaced along the elements pressed to said plate when said carriage is returned to the buffer station from said welding station.
Welding apparatus for attaching elongate reinforcing elements onto a metal plate comprising means defining a welding station including means for supporting said plate at said welding station to lie in a substantially horizontal plane, means defining a buffer station located adjacent said welding station, a cantilever beam extending over both of said welding station and said buffer station, a movable carriage having mounted thereon welding means for welding said reinforcing elements to said plate and means for releasably gripping said reinforcing elements, means mounting said carriage upon said beam for reciprocal motion along a generally linear path between said welding station and said buffer station, means for positioning said reinforcing elements in said buffer station with said elements extending longitudinally in a direction generally parallel to the direction of said linear path of said carriage means, and means on said carriage for pressing against said plate in a welding position reinforcing elements held by said gripping means when said movable carriage is moved to said welding station, said gripping means being arranged on said carriage to engage said reinforcing elements positioned in said buffer station when said carriage is moved from said welding station to said buffer station and to transport said elements into welding position relative to said plate when said carriage is moved from said buffer station to said welding station, said welding means being arranged on said carriage to weld to said plate reinforcing elements held in said welding position by said pressing means while said carriage is moving from said welding station toward said buffer station to bring said gripping means into gripping engagement with other reinforcing elements positioned in said buffer station.
