  • Publication number: 20090030542
    Abstract: In a flexible manufacturing system (FMS), a shelving module of a work cell is fitted with a dedicated lift conveying mechanism so that work materials of desired sizes may be retrieved individually from different shelves of the shelving module for conveyance to the machine of the work cell. By having its own dedicated lift conveying mechanism that operates independently from the transport system that transports raw materials to the wok cells of the FMS, the operation of each cell becomes unaffected by the transport system. As such, materials may be fed to the machine in each cell for fabrication, piece by piece if so desired, by the lift conveying mechanism while the various shelves of the shelving module continue to be stocked by the transport system. Any remnants that prior to the instant invention would have been wasted may be returned to the appropriate shelves of the shelving module for future use by the lift conveying mechanism.
