Abstract:
1. A system for exchange and reconditioning of winding or rewinding shafts associated with a web handling device comprising an omni-directional cart adapted to receive, support and store thereon at least one shaft in need of reconditioning and at least one reconditioned shaft, said cart including a base adapted to be moved omni-directionally upon a supporting surface, said base including first and second upright standards mounted on said base at laterally apart locations, a first subassembly adapted to be positioned at various vertical locations along the length of said first upright standard, and a second subassembly adapted to be positioned at various vertical locations along the length of said second upright standard, each of said subassemblies including an arm extending outwardly generally horizontally from a respective upright standard in generally cantilevered fashion, each such arm including an exposed upper edge and an outboard end, a height adjustment device operatively mounted on said base and in association with a respective one of said subassemblies whereby said height adjustment device is adapted to raise or lower its associated subassembly, independently of the other of said subassemblies, between various vertical locations along the height of its associated upright standard to position said arms of said subassemblies in underlying engagement with at least one shaft mounted in operative association with said web handling device and whereupon disassembly of said at least one shaft from said web handling device deposits said at least one shaft on said upper edges of said first and second subassemblies, a shaft storage cradle mounted on said outboard end of each arm at a location proximate said upper edge of said arm and depending from said outboard end of said arm in position to receive and temporarily store therein at least one end of said shaft mounted on said web handling device and in need of reconditioning, each arm of each of said subassemblies providing a support location for a reconditioned shaft suitable to be substituted for said shaft in need of reconditioning in anticipation of the removal from said web handling device of said shaft in need of reconditioning, said support levels being adapted to support said reconditioned shaft in an attitude whereby movement of said reconditioned shaft along said arms positions said reconditioned shaft for mounting of said reconditioned shaft on said web handling device in lieu of said disassembled shaft without adjustment of the vertical, horizontal or angular attitude of said cart.
