IntraWatcher PVLC label inspection system for cylindrical plastic packages
IntraVis Vision Systems of Germany, a global supplier of video inspection machinery, has released the IntraWatcher PVLC system, designed for the quality control of labels on cylindrical unoriented containers. It inspects pressure-sensitive, injection-moulded and heat-transferred labels.
IntraVis recognised the challenges that manufacturers face with inspecting the presence, position and identity of labels and decorations on cylindrical unoriented containers. The parts cannot be compared to a reference sample, as proper alignment is not guaranteed.
The system simplifies the inspection process as the optical inspection module takes images from all sides of the container using four cameras and creates a full 360º image. The images are then orientated, stitched together and the perspective is straightened by the image processing software. These images are then compared to the reference sample.
The system can inspect 10 parts/s and has special non-shadow lighting that provides consistent conditions during the inspection process.
The IntraWatcher PVLC inspects: presence and identity; measurement of label offset; measurement of angular position; print errors; and folds and bubbles.
