Color Measurement for Quality Assurance
Industry 4.0 Solutions for Compounding Extruders
In order to meet the ever increasing demand for data acquisition and analysis, KraussMaffei Berstorff GmbH, Hanover, Germany, has developed two new systems, which are available as options for ZE BluePower extruders.
The first of these developments is designed to synchronously collect all production data of a compounding line. It is composed of well-tuned hardware and software components for acquisition, recording, evaluation and further processing of all process and measured values. Data analysis provides a sound basis for process optimization, in particular when it comes to process modifications or planned quality improvements.
Thanks to its modular design and easy configuration, the system can be adapted to a wide range of different applications, scaled in size and is suited for interface-independent operation. All interfaces can be integrated into an overall system that collects and visualizes the desired process data. Pressure, temperature, speed and volume flow values of all upstream and downstream components – e.g. metering systems, melt filters, melt pumps and pelletizing systems – as well as the extruder parameters are combined in a single system.
The second development for in-line process monitoring is designed to detect instantly any metering errors in order to reduce production scrap and enhance line efficiency. This in-line measuring system is based on color measurement: light is projected into the melt, reflected and then detected by a high-resolution glass fiber sensor. Upon comparison with the previously defined setpoint, any deviation in terms of brightness or color is instantly recognized and indicated. It goes without saying that the color measuring system can be integrated into the overall line control.
