I have a tub randomly filled with light longitudinal parts like pencils or matches. My goal is to gather them into a buffer nicely aligned (independently of which end is facing side). What's the fastest way to achieve this? I have considered unconventional bowl feeder with substantial radius conveying part radially from the filled drum, what do you think? Also, linear feeder with a grooved vibro-plate but that still brings misaligned stacked parts. Is it solvable by stepping down the conveyor and putting up vertical constraints? Even then, how do I proceed to stack everything neatly? Any way to evaluate this theoretically?
