Norcross, Ga.-based Intravis Inc. introduced IntraWatcherPVLC, a new label vision inspection system for checking labels on cylindrical, un-oriented containers. These present a challenge for vision inspection, since you can't guarantee the orientation on conveyor belts, according to Intravis.
IntraWatcher PVLC is equipped with an optical inspection module that provides a 360-degree view around cylindrical containers. It creates a rollout image, and software straightens the perspective, then compares it to a reference sample.
The equipment inspects each container for the presence of a label, identify and positioning. It also detects printing errors, folds and bubbles.
