LABELLING PETplanet Insider Vol. 24 No. 07+08/23 www.petpla.net 24 LABELLING 1ST .& "" can inspect for short shots as well as blow byes. This ensures not only the quality of the decoration itself, but also of the decorated object. And the system also addresses the peculiarities of the IML process during daily handling. “We are aware that rapid product changes are the daily routine, especially in productions using IML labels. That’s why we equipped our IMLWatcher with a quick reference mode,” Janina Orlowski tells. This functionality helps the operator to create a new, ready-to-use reference within seconds and fully automatically. The subsequent reference evaluation also helps to find out the effects of an adjusted reference compared to the previous one. This ensures that only perfect references are activated. In addition to the already established solutions in the household chemicals and food industries, new industries are also increasingly experimenting with how they can incorporate IML decorations for their purposes. In this regard, Intravis recently announced with several partners that a new solution for IML-decorated medical products will be presented at this year’s Fakuma trade show. Sleeve labels with special requirements Compared to the other types of labels, sleeves pose special challenges for the vision systems currently available on the market. For this reason, Intravis decided to develop a system specifically designed for sleeved products, the SleeveWatcher. Undoubtedly, a major challenge is the glossy surface of sleeves. Compared to pressure-sensitive or in-mould labels, sleeve labels often lead to high reflections if illuminated incorrectly. These reflections, in turn, can result in the ejection of faultless products that actually meet all quality requirements. Intravis meets this challenge with a lighting technology. It illuminates the entire inspection area and, consequently, produces a very homogeneous light. This significantly minimises the risk of reflections but still detects typical defects like folds and holes. Another challenge presents the huge number of possibilities that can arise with sleeved objects. A large selection of object shapes with diverse combinations of colours, patterns and transparent label parts provides a particularly high degree of variation for sleeve labels. These elements, which make the sleeved product attractive to the end consumer, are often highly challenging for vision inspection. Due to the specially arranged hardware as well as a completely new developed inspection module for the IntraVision software, the SleeveWatcher is optimally adjusted to the challenging characteristics of sleeve labels. Thus, the system enables a comprehensive 360° inspection of the entire label. Once the SleeveWatcher is installed, it inspects 100% of the product flow at a speed of up to 15 parts per second. Thus, the system can easily keep up with even the fastest sleeve labelling machines, says Intravis. Its six side cameras inspect sleeves for common label inspection criteria such as presence, identity as well as horizontal and vertical offset. In addition, the system inspects for sleeve-specific defects such as smiling and frowning effects, folds, distortions, and holes. On request, code reading is also possible – with the same code range as known from the LabelWatcher. www.intravis.com About Intravis Intravis GmbH is well kown for vision inspection systems for quality testing in the plastics packaging industry.
