Parcel Inspection

The key challenge in developing the high-performance inspection system was the need for extreme precision and reliability in detecting even the smallest defects across a measuring width of up to one meter. Standard 3D sensors were not an option due to the unique demands of the application. The system required a sensor with high speed (up to 24 kHz) and exceptional accuracy (4,069 measuring points per profile) to ensure process-safe defect detection. Additionally, the solution had to offer flexible evaluation options through its AOI function while maintaining low maintenance requirements. Ensuring both performance and reliability was crucial, as neogramm and Dematic prioritized quality and risk minimization in their selection process.

The solution is based on AT’s economic ECS 4090 3D sensor, which continuously provides real-time updates on its performance and functional data, ensuring maximum reliability and preventing sudden failures. Its robust IP67 housing allows operation in harsh industrial environments, while strain-resistant M12 connectors guarantee secure power and data transmission. With a Gigabit Ethernet interface and compliance with the GigE Vision standard, the sensor easily integrates into any image processing software or existing system. After three months of intensive development and testing under real conditions, six fully operational systems with four 3D sensors each were deployed in a distribution center in early 2018. Since then, they have been running flawlessly without a single reported incident.
