Title: Magnetic force adjusting method for sheet separator and device therefor
Inventor: SUZUKI HIROMI
IPC: B65H3/60
Filed: 1999-05-31
Abstract: PROBLEM TO BE SOLVED: To adjust magnetic force of a sheet separator to surely separate stacked plates mixed hierarchically different plates to every one piece in every hierarchy by an absorber. SOLUTION: Stacked plates mixed hierarchically different plates W (WA to WD) are at these side edges struck a floater cover 15 as a struck member. Because a magnetic force generating surface of a sheet separator 5 is arranged from a struck surface of the floater cover 15 through a space G, the side edges of the stacked plates are sucked in a direction struck the struck surface by magnetic force. Magnetic force adjusting pieces 29 consisting of a magnetic substance material with a different board thickness are interposed in positions corresponding to each hierarchy of the stacked plates in a state adsorbed into the magnetic force generating surface 21. Because magnetic force of the sheet separator 5 passes each magnetic force adjusting piece 29, the magnetic force to the stacked plates is easily and moderately adjusted.  When the stacked plates are lifted up one by one with absorber 43, one plate W in an uppermost position is surely separated from the other lower plates W to convey by lifting up.
