AI sees more
Tethered caps have been mandatory for all non-returnable PET bottles since July 2024. In order to detect defects in these closures even more precisely and efficiently, KHS now relies on assistance from AI on its proven Innocheck TSI closure inspector.
The obligatory introduction of tethered caps in the EU presented bottle and beverage producers with a number of challenges: with numerous variants in bottle and cap design being processed and line capacities increasing, they had to find new solutions to continue to meet the high demands made of product quality and protection. This also applied to inspection technology, explains Nikita Wall from Labeling and Inspection Technology Product Support at KHS. “Tethered caps were rarely used before the EU directive came into force. Standard systems thus frequently reach the limits of their capacity where cap inspection is concerned.”
“In intensive field tests our AI-based fault detector has proved that it fully satisfies the high demands our customers make of quality assurance.”

AI-based fault detection
One smart way of identifying potential defects in tethered caps during cap inspection is KHS’ AI-based fault detection system, available with immediate effect. It makes use of patent-pending algorithms to analyze images of bottle closures in real time. While cameras log the caps in high-resolution quality, AI models evaluate this data. By applying deep learning, the models adjust to account for any new types of flaw found.
KHS’ AI-assisted system increases the accuracy and efficiency of control by the proven Innocheck TSI closure inspector. This option can be implemented on new and existing machines. “In intensive field tests our AI-based fault detector has proved that it fully satisfies the high demands our customers make of quality assurance,” emphasizes Wall.
Using high-resolution 360° imaging, the module checks that caps are intact and correctly seated and that there are no signs of damage.

Further projects in the pipeline
KHS is also planning on using AI for more of its inspection technology. Says Wall, “In the development team, we’re currently deciding which systems this would make sense for. AI solutions are a possibility primarily for complex requirements – and if they give our customers clear benefits.”
