Double Blank Detection in Sheet Metal Processing:
Double Sheet or Double Blank Detectors are required in blank destacker, sheet feeder,
robot loader, blank washers, blank lubricator, magnetic conveyors, or in the centering station
to provide die protection for stamping presses. Hidden parts detection enable poka yoke
verification in body-in-white production. When manufacturing tailor welded blanks - TWBs -
undetected double blanks can cause substantial tool damage. Roland Double Metal Detectors
for steel, aluminum, or stainless steel blanks are therefore an important precondition for press
automation. Fanning magnets can be helpful in the process. Improved gap-tolerant single probe
double sheet sensors can be mounted directly into vacuum cups. Non-contact dual head systems
are especially well suited for roll forming application, magnetic transfers as well as mechanical
rail transfers. Roland Double Sheet Detectors have proved their reliability in thousands
of installations worldwide.
