PVA Series

Long Bin Pick-to-Light

The EZ-LIGHT PVA pick-to-light sensors provide a reliable error-proofing solution for various operation systems. The light indicate to assemblers which items to pick and in which order to pick them.

Pick-to-Light Solutions

Several technologies and solutions are available for bin-picking applications for error-proofing processes. Light arrays prompt the operator for part selection with integral job lights, then reliably sense retrieval of the part, using an array of visible red or infrared sensing beams located in front of the bin.

Order Fulfillment

The system controller issues an instruction to pick an item from a particular location. The controller turns on the PVA’s job lights at the specified location. The job lights go off when an item from that location is removed. If multiple items are required from one location, the job light stays on until the correct number of items are removed. The bright light of the EZ-LIGHT PVA pick-to-light sensor makes it possible to see which part to pick from a distance, saving time.

Pick Sequence Indication and Pick Verification

A pair of EZ-LIGHT PVA pick-to-light sensors are mounted to a rack on either side of a bin. In response to a signal from a process controller, the PVA illuminates to show the assembler which part to pick next. When the assembler's hand enters and leaves the bin, the controller recognizes that the part is picked and lights up the PVA for the next bin in the pick sequence.

Part Removal Verification in Automotive Assembly

In an automotive assembly plant, temporary pins—called grenade pins—are used to attach some parts temporarily. To make sure the grenade pins are removed, the inspection station includes a container for the pins that is equipped with an EZ-LIGHT PVA pick-to-light sensor.
