  • Patent number: 5348141
    Abstract: A material handling system particularly adapted for irregular or headed workpieces having easily damaged surfaces. The handling system receives and takes away from a multitude of process machines, by elevating, conveying, storing and distributing in a singulated pocketed fashion so as not to cause damage to the workpieces. The system lowers the workpieces and accumulates them in a central fashion to provide a storage or staging area to keep a constant flow to the next process machine. Bifurcated L-shaped pick-up forks are used to elevate the workpieces to a horizontal conveyor which includes a plurality of adjacent pocketed carriers forming a continuous surface. Each carrier holds a single workpiece. The workpieces are individually removed from each carrier and are passed through a tube which centers the parts between a pair of adjacent belts for staging.
