Retroreflective light array for lean manufacturing

16 June 2013

Banner Engineering's PVL Parts Verification Array (PVL), with retroreflective technology, provides quality visibility, quick response time and wide, reliable coverage to help streamline pick-to-light and conveying processes.

“The fast two millisecond response time and wide coverage area make the PVL an ideal solution for applications beyond pick-to-light,” says Chuck Dolacek, Director of Product Development for Lighting and Indicators. “Detecting medium to large sized objects moving at high rates of speed—like boxes on a conveyor—are cost-effective uses for the PVL.”

The PVL light array features opto-mechanical alignment with bright red emitter beams spaced 70mm apart for easy set-up and installation. To ensure effective light-guided assembly in diverse applications, the PVL is available in two lengths — 225mm  or 500mm - and can be mounted either vertically or horizontally to racking systems.

Upon applying the supplied retroreflective tape to an adjacent PVL or accessory bracket, the PVL’s emitted light beams are directed to the tape strip and a highly visible indicator arrow lights up to notify users which bin to pick from.

As the operator reaches into the bin, the light beam is interrupted, triggering an output to the control system indicating the correct parts have been selected. Picking from the incorrect bin causes the arrow to turn red and also sends an output signalling a miss-pick error.
