  • Storage conveyor
    Patent number: 7748515
    Abstract: A storage conveyor that secures a number of stored workpieces while saving space is provided. When a sprocket on a driving side is driven to rotate in a forward/reverse direction by a chain drive motor, opposing bend suppression members between a pair of chains are successively engaged/disengaged, and an opposing portion between the pair of chains is extended/retracted with respect to a workpiece conveyance surface. Thus, workpieces are passed between the workpiece conveyance surface and workpiece receivers. Consequently, the workpieces can be stored in a vertical direction (up-down direction), making it possible to secure the number of stored workpieces while saving space.
