Battenfeld Extrusions-technik GmbH, which has got a joint venture with Kabra Extrusiontechnik Ltd. in India, has developed a modular concept consisting of three components: energy monitoring, production monitoring and maintenance monitoring. The system is integrated in the BMCtouch client-server operating system, so that all relevant data can be clearly shown at any place and at any time. This concept has been designed specially to simplify monitoring of all extrusion line parameters.
The first system of this type is currently operating as a pilot project at a well-known customer from the PVC window profile industry - with very promising results.
Monitoring and visualizing the energy flux in extrusion lines is the most important part of the new system. The energy monitoring module measures the energy flows in the machine and visualizes the distribution of energy. From such measurements, it calculates the specific energy consumption per kilogram of the manufactured product, so that the processor is provided with a final value for making meaningful comparisons. In addition, the measurement of partial energy flows facilitates the optimization of extrusion process technology. Last but not least, energy flux monitoring also enables processors to evaluate measures aimed at cutting production costs by increasing energy efficiency.
Maintenance monitoring, the second component of the new system, supports preventive maintenance of extrusion lines by means of maintenance alarm signals. Service intervals are included in the calculation, and model calculations are carried out for machine components with a load-dependent service life, such as drive systems. Maintenance logbooks ensure reliable documentation of servicing that has taken place. True to the principle of “better safe than sorry”, this monitoring component helps processors to carry out preventive maintenance according to a plan, and thus avoid unintended downtimes as far as possible.
Production monitoring, the third system component, automatically collects data about the production status of a line, such as setup times, uptimes and downtimes, and calculates production key figures from these data. Processors are thus able to make direct comparisons between the production key figures of different extrusion lines. On the basis of this information, the extrusion process can be optimized and the line runs more efficiently.
Thanks to the various monitoring functions, processors are able to optimize the efficiency of their extrusion lines. Here, the calculation of specific key figures is a decisive contributing factor, since, in addition to direct comparison between different extrusion lines, it enhances and facilitates the optimization of individual lines
