New development of QCS integrated with machine monitoring system

To remain profitable, today's papermakers must increase their machine speed and efficiency, while maintaining a high-quality and uniform product. Often times, however, faster speeds result in more frequent web breaks and also in more short-term quality variations. The Honeywell-Measurex TMMS (Total Machine Monitoring System) Product Quality Monitoring application module uses parallel processing to continuously and simultaneously measure the machine direction sheet quality variations from the product scanner. And WMS (Web Monitoring System) includes a set of high-speed video cameras positioned along the machine to continuously monitor the web. Typically rotating components such as fan pumps, screens, Calender rolls, Press rolls and felts causes paper quality short-term variations. Feedback from TMMS is used to increase machine runnability and efficiency by providing information required for decisions to adjust felts, change press loadings, and remove, repair or grind rolls, and adjust stock approach components. With the resulting set of high-resolution pictures of the web break from WMS, operators can focus on the specific problems which cause web break, and then make the necessary changes in machine operation to optimize paper machine performance and efficiency. The Honeywell-Measurex new QCS (Da Vinci) successfully integrated with TMMS and WMS will supply new features of total machine diagnostics as well as CD and MD quality controls to keep maximum efficiency of the paper machine.
