Automatic Disk Stacking Device

The portable stacking device stacks and holds a series of disks without contact of adjacent surfaces and use of spacers between adjacent disks.

The device includes movable platform 1 on which are mounted three lead screws 2, 3 and 4. These screws are parallel and are spaced 120 degrees apart around a vertical center. A.gear 5 on the base of each lead screw meshes with central gear 6. The latter is driven in a forward or reverse direction through clutch 7 and reversible motor 8.

To load a disk onto the device, the central opening of the disk is placed around the upper ends of the lead screws. A switch is operated to cause each of the lead screws to make one revolution in the desired direction. The initial thread of each screw engages the edge of the internal opening moving the disk downwardly. As each disk is loaded onto the device, the earlier disks are moved downwardly toward the platform. To unload the device, the procedure is reversed.
