HPINet Web Inspection System – DIRT Count

Accurate dirt detection, imaging and classification all play a crucial role in quality control and process improvement for pulp production. ABB’s Dirt Count web imaging system meets today’s demands for increased quality and runnability with 100% inspection of pulp and reduced customer claims.

Real-time defect detection
Using high resolution CMOS digital cameras together with advanced machine vision tools to improve performance, the Dirt Count System provides an exceptional level of real-time defect detection on the fastest and widest modern paper machines. Real-time detection of dirt and shives in pulp allows operators to take corrective actions earlier, resulting in improved production yield, improved quality and reduced customer claims.

Defect size classifications to ISO/TAPPI/ANSI standards
Dirt detection and analysis are performed by specialized, high-speed FPGA devices. Automated detection and counting yields consistent and repeatable results leading to improved grading of production. Defects as small as 0.02 mm2 may be detected which enables ABB’s Dirt Count System to fully comply with all defect size classifications of ISO/TAPPI/ANSI standards. Connectivity to mill-wide systems and integration with ABB P&P automation systems ensures that defect data can be acted on at the quality management and process control levels.
