Data collected from this research has led to the development of the FlexRadar system. This glass forming process analyzer quickly identifies deviations in the glass forming process by monitoring the container’s glass distribution, geometry as well as its position on the conveyor.
The FlexRadar system incorporates Short Wave Infrared Imagers (SWIRs) positioned directly after the IS machine on opposing sides of the conveyor. These SWIRs provide images of the sidewall of each container for maximum coverage and improved dimensional profiling of each container.
The images produced by the SWIRs are processed using proprietary algorithms to identify cavities that stand out from the overall population of all cavities. The deviations used to identify the outliers are based on the container’s vertical and horizontal glass distribution, dimensional outline including lean, and the position on the conveyor. Cavities or sections producing outlying containers are quickly identified and visually displayed to the machine operator.
Development of additional features for the FlexRadar system continues at the Emhart Glass Research Center (EGRC). The focus is on closed loop controls by exchanging container information with the FlexIS machine control. These developments are aimed at automatically reducing process variations during container forming.
