Abstract: The pattern Recognition System uses a Radio Frequency Identification (RFI) tag embedded in the pattern to enable the mixer to recognize each individual pattern's requirements. The RFI tag itself is approximately 32mm long, 5mm diameter and can be positioned anywhere in the pattern impression or box frame. Once the antenna reads the RFI tag, the information is passed to the PLC in the mixer control panel and starts the automatic mixing cycle. When either reclaim or blend sand is selected, the mixer starts and mixes the required quantity of sand, near to the end of the pattern filling the compaction table will start and vibrate for the set time and frequency determined by the tag. Obviously, the main benefits of pattern recognition are to reduce the chances of human error, maximize mould-making efficiency, reduce costs and improve production record keeping.
