Vision System Sorts Good Pellets From Bad Using Color
The ScanMaster II is an electronic color sorting machine that sorts virgin resins (checking for speck damage in pellets, off-color pellets and cross-contamination) as well as recycled resins (green from clear PET, colored from natural HDPE and different colors in regrind). Unit can process up to 10,000 lb/hr.
The machine uses CCD (charged coupled device) cameras to detect spots smaller than 0.3 mm. Up to 80 individual ejectors help ensure that a minimal amount of acceptable product is removed with each burst of compressed air used to remove the offending product.
Unit has a color touch-screen with up to 100 presets for quick product changeover. A graphical display of ejector firing rates promotes a higher quality yield from a more consistent sort. A 'frame grab' feature shows actual product images. Unit also provides a diagnostic display of the maintenance log and run time statistics to help reduce downtime.
Prices range from $60,000 to $135,000 depending on capacity.
