Papermakers benefit from Voith’s new OnQuality fiber orientation measurement and control
- Precise and continuous measurement of the fiber orientation profile
- Fully integrated QCS control of fiber orientation
- High savings due to the avoidance of B quality
Due to the precise control possibilities, major international packaging paper producers already rely on the application to ensure their product quality. After a short rebuild and commissioning phase, the investment pays for itself in most cases in less than a year. The integration of the quality control system is applicable for existing plants worldwide and independent of the manufacturer with little effort.
Functional principle of the new automation solution
The OnQ Fiber Orientation Sensor uses high-resolution macro photography, digital image processing and nanosecond flash illumination to distinguish the individual fibers and their orientation in the moving paper web. Surface measurement is possible on both one and two sides. The OnQ Profilmatic CD control system derives suitable set points of the OnQ ModuleStep actuators from the measured fiber orientation angles, which enable zonal, mechanical profiling of the headbox slice lip using stepper motors. In combination with the OnQ ModuleJet actuators, the dilution water can also be controlled, thus avoiding undesirable side effects on the basis weight.
OnQuality 4.0
Voith's OnQuality 4.0 is an intelligent and integrated concept that enables manufacturers to gain control over production processes and product quality. A broad portfolio of scanners and sensors ensures reliable and continuous measurement of various quality parameters. The intuitive apps of the cloud platform OnCumulus provide a wide range of analysis, reporting and visualization functions that are available at any time via different end devices and optimally complement the fiber orientation solution. In addition, the paper technology experts at Voith's OnPerformance.Lab provide support to further increase the efficiency and productivity of the plants with the help of remote consulting and optimization.
