MURRAY Goulburn has installed a Ward checkweigher at its Koroit plant. The system has removed the problems of rejected product and repeated line stoppages while dealing with severe space limitations and heavy product.

Space was conserved by mounting the reject arm above the check conveyor which, at 1200mm, is only 300mm longer than the bags of milk powder passing over it. The weigher section was fitted with a low-friction belt to protect the sensor system from the sudden horizontal shunting loads during ejection. The reject system performs double duty by taking reject commands from a metal detector. Before this system was installed bags suspected of contamination would cause the line to stop until they could be removed manually.

Software reports whether rejection was caused by metal contamination, underweight or overweight contents. Records are automatically maintained. Up to 50 different product set-ups can be programmed into the control system which is fully integrated with the line PLC.
