The system was designed to monitor 3 wire frame coating lines. Primarily this was aimed at determining accurate reasons for any stoppage periods.
Having collected a few weeks of down time information, the management were in a position to perform a Pareto analysis on the data and then target specific reasons to improve the productivity of each of the lines.
PVC Coating Line Monitoring
An interlock mechanism was employed to force the operators to enter the reason for any down time of over 5 minutes. This data was then recorded into shift based batch files for later analysis.
Detailed reports of all stoppages and product throughput, covering everything from a single shift through to several months of running, were then available to the management.The system was also set up to monitor a series of furnace temperatures. These were recorded to provide detailed historic trend graphs so that the performance of the furnace could be monitored under different conditions. As a result of this, the required warm up times for the furnace were found to be several hours less than had been assumed for many years.
