KHS Innocheck TSI closure inspector

Tethered caps have been mandatory for all non-returnable PET bottles in the EU since 2024. Consequently, the number of closure variants and thus the demands made of inspection technology have increased. KHS GmbH is meeting these new challenges with the help of artificial intelligence (AI) — Innocheck TSI closure inspection unit is now equipped with an AI-based fault detector.

With its AI-based fault detection system for tethered caps, the Dortmund turnkey supplier now provides smart engineering that identifies potential defects during cap inspection. The new module makes use of patent-pending algorithms to analyse images of bottle closures in real time. Cameras log the caps in high-resolution, while AI models evaluate this data. By applying deep learning, the models adjust to account for any new types of flaw found.

The KHS AI-assisted system is designed to increase both the accuracy and efficiency of inspection. Foundation for further projects KHS has developed the new system specifically for its Innocheck TSI cap inspector. It can be implemented on both new and existing machines. 

In the future, KHS also wants to use AI for further inspection technology equipment.
