  • Patent number: 10329102
    Abstract: The present invention is directed to a method of loading workpieces using a piler conveyor P including a first conveyor which sequentially conveys the workpieces by continuous operation at a first speed, a second conveyor which magnetically attracts, on a lower surface, the workpieces passed from the first conveyor for sequential conveyance by intermittent operation, and a loading frame where the workpieces are placed, the method including a first step S1 of gradually accelerating the second conveyor to the second speed, a second step S2 of operating the second conveyor at the second speed and passing the workpieces 1 from the first conveyor to the second conveyor, a third step S3 of gradually decelerating the second conveyor from the second speed for operation, and a fourth step S4 of stopping the second conveyor and causing the second conveyor to lose a magnetic force and dropping a workpiece 1 positioned above the loading frame onto the loading frame 30, wherein the first speed and the second speed are set
