Machine Vision world pulppaper92 With hundreds of WMs systems operating it has become clear that this technology provides an effective means of solving breaks and provides a rapid return on investment that experience has proven that many believed to be known sources of breaks have actually been found with cameras to be originating from another source in other words they actually were unknown. A further WMS result is that preventive measures can be taken prior to a break occurring. This can be achieved today with automatic triggering of cameras as soon as they see a change in the sheet from a normal condition. Essentially all WMS cameras today perform in the same way as web inspection cameras Figure 4. Shows how a fully integrated single platform web monitoring WMS and web inspection WIS operator station that allows a defect to be automatically transferred from the WIS to the WMS system synchronised to the same piece of paper. This allows for a rapid and accurate means for the user to find the source of the defect and to eliminate it. A single keyboard and mouse is able to operate both systems. and can be set up to trigger at all types of changes in the sheet and surrounding conditions. Examples of such changes could be problems occurring on trim squirts and felts sheet flutter sheet tension vibration and various condensation and operator errors. With hundreds of WMS systems operating on all types of paper board pulp and tissue machines it has become clear that this technology provides an effective means of solving breaks and provides a rapid return on investment often less than 6 months. With a sufficient number of cameras correctly placed a complete picture of the event can be achieved from any part of the papermaking process. The elimination of all unknown breaks is a function of several variables such as type of camera system type of break similarity of breaks number of cameras camera locations and user capabilities and commitment. It should be noted that with the advancements that have now been made in WMS technology it has become much easier for operators to find the root causes of breaks and defects.
