New-generation web inspection system from Valmet
and paper producers to inspect and improve product quality in greater detail has been launched by Valmet. IQ WIS works in real time, enabling immediate root-cause analysis and corrective action, and is one of the integral elements of the IQ Process and Quality Vision system; another element being the IQ Web Monitoring System. It was developed in collaboration with Munich-based Dr Schenk, a global supplier of inspection and measurement solutions. Marko Toskala, director of
A
quality management systems within automation at Valmet, commented: “The collaboration between Dr Schenk and Valmet is a showcase of excellent synergy by smartly combining the know- how and experience from the world’s best inspection system provider with a world-class paper
new-generation IQ Web Inspection System (IQ WIS), which enables board
process specialist. “After having delivered a total of 450 Valmet IQ Process and Quality Vision systems globally, this new product launch is an important step toward even higher precision in quality control. Valmet continues to support the existing installed base and offers a seamless upgrade path. The advantages offered by the new features can be integrated into existing systems through upgrades.” Dr Peter-M Heinze, sales manager at Dr Schenk, added: “We are pleased with the development of the new Valmet IQ WIS. Valmet is the frontrunner in the pulp and paper business. Through their strong sales and service organisation, we can offer our leading inspection technology to these processes globally.” The IQ WIS is said to utilise
intelligent 8K camera technology, which combines the best features of an area scan (matrix) camera and line scan
camera technologies. It enables immediate identification of production that does not meet quality criteria through a wide range of technical features. High measurement precision
can be reached even with higher maximum paper web speeds. More sensitive and reliable defect analysis can be achieved with multi-geometry. It is also possible to replace several camera beams with one unit, resulting in cost- efficient, compact installation and lower service needs. The latest IQ WIS technologies
provide paper processors with the means to achieve better quality monitoring and control. Unique
lighting technology enables the detection of print-critical defects that have not been visible before. This illumination provides excellent opportunities for 3D defect contrasting. Particularly, longitudinal structures and oil stains, for example, which are often hard to detect with standard lights, are also highlighted. Precise detailed defect classifications can be made by means of the MIDA (Multiple Image Defect Analysis) and the latest software algorithms based on artificial intelligence principles. Valmet Industrial Internet solutions can utilise the data from the web inspection system to further benefit customers. A comprehensive process picture is created by combining the data from the quality control system and the machine vision system. By adding other key process data, it is possible to find better ways to ensure desired process performance and end-product quality.
More two-drum winders from Voith
VariFlex Performance is a new two-drum winder from Voith that is said to set new capacity standards with a design speed of 3,000 metres per minute and a 25-second set change time. This results in a significant
increase in both efficiency and productivity in a working width up to 10 metres.
“With VariFlex Performance, Voith has developed a new high-capacity winder that is designed from scratch to fulfil all customer demands.
May/June 2019
Consequently, this winder fully focuses on the best winding quality, reliability and maximum production,” says Christian Woelfel, head of application at Voith.
Daniel Juergens, global product manager at Voith, adds: “VariFlex Performance is our foundation for implementing full digitalisation and connectivity in the end section.
“In combination with our upcoming developments in the end section, this winder is a
central element to bring key features – such as predictive winding, fully automatic process communication and highest winder throughput – to the next level.” The Gecko OneStep system ensures reliable start and end gluing. Further boosting of the winding performance is achieved with SmoothRun technology. This active drum dampening system significantly reduces paper-induced vibration, leading to an increased capacity.
Live condition monitoring and a clear system analysis are features of the automation system. In addition, the system provides an easy data exchange to the mill system and enables the integration of automatic jumbo roll identification. VariFlex Performance will be delivered specifically in five main assembly modules. All modules are placed on common foundation rails, which simplifies alignment work as well as the civil engineering process.
