The web monitoring system is now more compact in size. Its enhanced features provide pulp and papermakers with higher-quality images than before for analysis purposes, enabling them to take virtually instantaneous corrective measures. These features maximize production line efficiency and product quality.
“We have made major changes to our web monitoring system when it comes to its camera, LED light and system structure. These improvements enable papermakers to focus faster on specific web problems and avoid profitability losses,” says Aki Torvinen, Business Manager, Machine Vision, Automation Business Line, Valmet.
Compact and modular camera
The web monitoring system camera is compact in size and has a modular structure. Modularity allows the use of different kinds of cameras and optics, such as a manual or motor zoom, or pinhole optics. Furthermore, a separate washer can be added if the camera is located in a challenging environment where cleanliness might present a problem.
The camera is equipped with the latest high-sensitivity Sony CMOS sensor. It is also possible to use a color camera.
New efficient LED light
Unlike the previous model, the Valmet IQ Web Monitoring System has a separate compact LED light module that is synchronized with the camera. This allows better optimization of the light pattern and its direction (patent pending). In total, 140 LEDs are included that feature the latest LED technology. A light output of 45,000 lumens is reached with only 35 watts of power.
Easy to install, use and maintain
The renewed web monitoring system is fully compatible with older generation systems. Data is transferred through standard 1 gigabyte Ethernet components. Due to the low number of components, the system is easy to install, use and maintain.
Technical description of the Valmet IQ Web Monitoring System
The Valmet IQ Web Monitoring System is one of the two elements of the Valmet IQ Process and Quality Vision (PQV) System, a comprehensive machine vision solution. The other element in the PQV system that Valmet launched in 2015 is the Valmet IQ Web Inspection System.
The Valmet IQ Web Monitoring System records video images of the crucial events in the process, such as web breaks, tail feeding and defects triggered by the IQ Web Inspection System. Recorded images are available for playback, enabling operators to quickly find the origin of the event and correct the problem. This shortens downtime after breaks and improves runnability. Optimized machine efficiency delivers fast payback on investment.
