 Permanent Magnetic Sheet Fanners
 
Our standard permanent and electromagnetic Sheet Fanners and Separators are designed to separate steel sheet stock.
 
As sheets are placed against the sheet fanner, the powerful magnetic field automatically forces the sheets apart and separates them from one another. Manually prying apart sticky, oily sheets is no longer necessary and die damaging double blanking problems are eliminated.
 
The flexible mounting design gives you more options to match your application needs. Use the handle and base plate for portable applications or use the tapped holes to bolt the fanner to your equipment or tooling.
 
Note: Choose a fanner with a height 2-3 inches taller than your maximum stack height.
 
Typical Magnetic Sheet Separator Installations: For best results, locate the magnetic fanner at the corner(s) of large sheets and in the center of the width of length on smaller sheets. Fanners placed opposite each other on small sheets will actually float the sheet.

 Electromagnetic Sheet Fanners
 
Electromagnetic Sheet Fanners eliminate die-damaging, double-blanking problems in automated sheet handling operations. A powerful electromagnetic field automatically separates the sheets. As fast as the top sheet is removed, the next sheet instantly moves up.
 
The on/off capability of the Electromagnetic Sheet Fanners provide operator safety during steel blank stacking and un-banding. This on/off control makes cleaning around magnets easier when sheets are not fanned. For automated presses, the electromagnetic fanners are controlled to operate simultaneously with other destacking equipment.
 
Electromagnetic Sheet Fanners require conversion from AC to DC voltage. IMI power supplies are designed to properly convert voltage and provide for operation of single or multiple fanners. IMI power supplies (see Tech Sheet AG-09A) can be equipped with a variable output to adjust the magnetic strength to handle a variety of metal thicknesses.

 Magnetic PinFanners™
 
Our Magnetic PinFanners™ are designed to separate stacks of steel sheets or blanks on "Hex", "Round" or "T-Slot" pallets. These fanners have dual functionality; they act as guides for aligning parts as they come off the blanking press and also as magnetic sheet fanners that fan or separate multiple sized or shaped blanks for the manual or automatic loading of a press.
 
Multiple magnet positions ensure direct contact with the blank for maximum fanning ability, and since they are mounted directly to the pallet, there's less down time and maintenance on the line.
  • PinFanners™ function as both pallet pins and sheet fanners
  • Magnetic circuit rotates 180º internally to suppress the fanning action
  • Pallet mounted fanners require less maintenance time on the line
  • Assured contact with blank to maximize fanner performance
  • Works with multiple sizes and shapes of blanks
  • Powerful, Rare Earth permanent magnetic circuit
  • Standard "Hex Pin", "Round Pin" or "T-Slot" mounting available
  • Offset mounting for optimal pin to stack positioning

Note: PinFanners™ must be used in pairs. Each part number below includes 2 pin fanners, one of each polarity (North & South pole).

 Magnetic SheetSeeker®
 
IMI's new lightweight SheetSeeker® fanner is a breakthrough in magnetic sheet separation technology!
 
First, the permanent magnetic circuit is lifted and locked into place for introduction to a stack of steel sheets. Then, once the materials are in place, the sliding magnet is unlocked and automatically centers on the top of the stack and fans the sheet stock. As each sheet is lifted off the stack, the magnet indexes down automatically and will fan to the bottom of the stack.
 
Features & Benefits
  • Features a powerful rare-earth, automatic indexing, permanent magnetic circuit
  • Up to 60% lighter than standard sheet fanners with the same strength!
  • Durable stainless steel construction
  • Light-weight design and convenient carry handle allows for easy transport
  • Custom designs and options available upon request

 Air Cylinder Sheet Fanners
 
Air Actuated Sheet Fanners have an air release system that pulls the magnet inside back away from the face of the fanner, This allows you to easily and safely remove the fanner from the
stack.
  • Reduce costs & increase safety for destacking steet sheet stock
  • A powerful, Rare Earth magnetic field automatically separates sheets
  • As the top sheet is removed, the next sheet instantly fans up
  • Assists prying apart sticky, oily, pre-finished or polished sheets
  • Eliminates die-damaging double blanking in automated operations
  • ON/OFF of an electromagnet with the benefit of a permanent magnet
  • Allows for mid-stack change over

Permanent Magnetic Fanners handle steel sheets of almost any length, width or shape. The sheets near the top of the stack seperate instantly from a 3/4" to 1-1/2" gap, depending on sheet thickness and size.

 Air Knife Fanners
 
Permanent Magnet Sheet Fanners with Air Knives allow for ferrous and non-ferrous sheets to be separated in stacking/destacking applications. While the magnet force will work with all ferrous metals, the air knives separate all non-ferrous metal by pushing air in between the sheets causing them to rise up from one another.
  • Reduce costs & increase safety for destacking ferrous and non-ferrous sheets
  • A magnetic field automatically separates ferrous sheets
  • Powerful air knives automatically separate non-ferrous sheets
  • As the top sheet is removed, the next sheet instantly fans up
  • Assists prying apart sticky, oily, pre-finished or polished sheets
  • Eliminates die-damaging double blanking in automated operations

Permanent Magnetic Fanners handle steel sheets of almost any length, width or shape. The sheets near the top of the stack separate instantly.

 Air Spring Sheet Fanners
 
Air Spring Fanners have an air spring system that pushes the magnet inside toward the face of the fanner when air pressure is present. When the air pressure is turned off or disconnected the air spring will defl ate and the magnet will move away from the face of the fanner creating air gap that in essence turns the magnet off. This removes the risk of having metal accidently attracted to the fanner during transportation or stack changeovers.
  • Reduce costs & increase safety for destacking
  • A Powerful, Rare Earth, magnetic field automatically separates ferrous sheets
  • As the top sheet is removed, the next sheet instantly fans up
  • Assists prying apart sticky, oily, pre-finished or polished sheets
  • On/Off capability helps prevent injury when introducing new materials to the fanner
  • "Fail-Safe" mode automatically returns the magnet to the "Off" position with loss of air pressure
  • Durable stainless steel welded cover construction
  • Fans from 30 gauge sheets to 3/16" plate
