This sounds like the most promising idea. Yes there is vacuum for dust collection.

Use a laser either scanned across at high speed (something like a LaserJet II or III scanner) or expanded to a line with a spreader prism. Angle the laser with or against the conveyor travel so the pockets distort it from a straight line. Have the vision system look for distortions of a length range that corresponds to the pocket size, then move the nozzle to there (with adjustments for time delay of the move + belt speed) and cut loose with a burst of air. What about where the dust is going? Is there a vacuum system? --- This email is free from viruses and malware because avast!
