Targeting defects with intelligent inspection

Providing machine vision inspection systems to glass container manufacturers typically within the food and beverage sector, Antares Vision Group advocates accurate inspection to protect product quality and brand reputation. Brian Ensinger shares the company’s latest solutions.

Targeting defects with intelligent inspection

All glass container defects compete for the optimal lighting geometry within an inspection station. Often users are forced to compromise – as the target defect is emphasised, others can become harder to see. Antares Vision Group’s Volcano glass inspection systems solve this problem while performing at full line speeds.

Advantages of the Volcano systems include the ability to perform complete container inspections with greater accuracy and to detect even the most problematic checks. By helping to pinpoint the root cause of defects, costly wasted material and false rejects can be eliminated.

An inspection system should make no concessions for different types of defects. Volcano allows virtually any inspection sequence to be implemented, as per the requirements of the plant.

Smarter inside

Antares Vision Group’s Volcano inspection system combines practical tools that help plant quality assurance controllers pick up more anomalies.

Sentinel: Learns what is normal and abnormal by training on glass containers. Savings can be achieved when machines ‘know’ precisely how much dimensional variation to allow.

Blob Classifier: Locates anomalies, grades each by severity, and allows users to apply adjustable criteria to determine which (if any) are defects.

Adaptive Locator: Registers the sealing surface or sidewall in the image, taking the burden of location set-up and recall away from the user.

Surface inspection

A standalone, self-contained solution optimised for sealing surface inspection, Cyclops offers new users an easy-to-install introduction to the capabilities offered by Antares Vision Group. The In-line inspection machine checks the quality of glass containers, performing an inspection of the sealing surface. It can detect chip finish, wire edge, over press, line overs and blisters. Cyclops offers the same powerful inspection tools and algorithms available in Volcano products, with inspection settings
and job positions saved for easy
recall and repeatability.

Cyclops can be enhanced with Antares’ patented illumination process, ‘MultiView’, which creates a structured distribution of multicoloured light. This simultaneously provides multiple imaging geometries captured by a single image, reducing the time required to set up machines to optimise inspections, regardless of ware, shape or defect type.

Proven technology

Inspection systems from Antares Vision Group are powered by Applied Vision technology used in some of the most complex bottle making operations. For 25 years, patented optical, lighting and electronic image capture techniques—combined with advanced digital processing capabilities, proprietary algorithms and intuitive user interfaces—have enabled the company’s machines to operate more efficiently and reliably while adapting to normal process variation challenges in manufacturing and packaging plants.
