This minimises set-up times and almost entirely prevents errors caused by incorrect operation. The basic system with a camera and telecentric lens creates an image of the entire case width for each bottle row. The individ- ually recorded images are compiled by software into an overall picture that includes every detail. The tasks performed at the Bad Dürrheimer mineral spring required the installation of an additional optic module. This enhancement module includes an additional camera and additional LED UV lighting. The two cameras each record one image per bottle row, the first in daylight and the second using ultraviolet light. The individual images are combined after the case has passed and are examined by the recognition soft- ware for the recognisable bottle features. Each case is therefore examined in two independent images. The different lighting methods enable the checking of features such as contours, labels or especially the carrier rings, which may not be visible in the basic facility or can be covered by other features. The wear-resistant high-performance LED lighting modules are sensibly installed above the transporter level and are therefore protected from dirt and damage, thus minimising maintenance requirements. Recognition software An outstanding part of the BBull empties management system is the application of uni- versal image processing software “BBull Image”. Each individual The empties cases are brought at a set distance before the measuring bridge of the “BBull 500 Compact LG”, checked and errors are sorted out. Up to 7,000 cases per hour are checked against numerous criteria by a dual lighting module and ultrasound sensors.
