Batch numbers must be verified when filling and labelling cosmetic jars. However, the label can be rotated as required. Rotational tracking with a required cycle time of 600ms is best solved with the CV-600 vision system. The character set and the target specification string can be very easily taught-in by the operator. As there is only limited space available for the camera and lighting, a camera with a small design and a lens with a short focal length are chosen.
