Magnetic Stacking and De-Stacking Conveyors

June 3, 2006

Designed to boost production and cut costs, Sheet Stackers use reliable, economical permanent magnets, adapt to a wide range of applications, and can easily be integrated into automated material handling systems.


Magnetic Stackers move sheet metal components directly from existing conveyors, punch presses, stamping or blanking operations, and other production machinery. They transfer, index, and stack the sheet metal components at preselected destination points. Powerful permanent magnets inside the Stacker’s rugged, stainless steel conveyor securely hold each ferrous sheet while it is transported to the stacking point. There, the sheet triggers a sensor that disengages the drive motor clutch, activates a brake, and releases the sheet above the stack. A cycle timer and air valves reposition the magnetic element inside the conveyor to accept the next sheet. The released parts can be stacked on a pallet, conveyor or other surface, in any desired quantity, ready to be conveyed, moved, or shipped. The stacker can also be set up to convey rejected parts to a separate location.


Sheets touch only the belts, avoiding damage to delicate parts and finished surfaces. Painted or oily parts require no special handling. Permanent magnets never wear out and won’t send parts flying or create jams during power failures. Stackers cycle quickly and are simple to maintain. Sheet handling and material handling time are greatly reduced. With fast, automated sheet stacking, production machinery can be used more efficiently. Consequently, production costs per unit drop significantly.


Stackers can be configured to stack and to destack a wide variety of ferrous materials in many shapes and sizes. Examples include sheet stock, finished components, and production scrap. Adjustable Stackers can be designed for quick changeovers to handle sheets with different dimensions.
