Medical Stocking Inspection System
Description
DEFIS Medical Stockings is an automated inspection system for almost complete quality control of medical compression stockings after the knitting process. It combines special camera technology, coordinated lighting, and AI-supported evaluation. The integrated turning function enables double-sided inspection in a single process.
Automated inspection system for medical compression stockings
The system largely replaces the previous manual visual inspection: stockings are laid out on a conveyor belt, transported automatically, and inspected on both sides. Defective items are then sorted out mechanically. This makes 100% inspection time-efficient and cost-effective.
What does our technology do?
The system enables a throughput of up to 10 items per minute and detects up to 10 defect classes. It also checks for dimensional deviations (e.g., length and width). The inspection works for both beige and colored compression stockings and is independent of the stocking shape (with or without foot section).
Integrated optical quality control
The system takes pictures of each stocking and evaluates them automatically using AI-based software. The turning function ensures that both sides can be checked immediately. This results in consistent, documentable quality control without the subjective deviations of manual visual inspection.
What can DEFIS Medical Stockings detect?
It detects spots, lines, fibers/foreign fibers, holes and tears, knots, and fiber defects, among other things. The system also identifies deviations in dimensions (especially length and width). This allows both visual defects and fit-related deviations to be reliably sorted out.
What can it be used for?
The system is designed for quality control in the production of medical compression stockings, especially immediately after knitting. It is suitable for standardizing final inspections and reducing manual inspection efforts. The software and database can be adapted to specific requirements and expanded to include customized defect detection.
