Parts / Piece Counting Systems

Eye Counting vs Weigh Counting

Eye counters are not 100% accurate.  Two parts can be counted as one, if there is not a sufficient differentiation gap; incomplete parts, scraps of metal, etc., can be seen as a “part.”  (This is not true of an escapement counter.) The important point to remember is that when someone wants “real” counting, which most people take to mean “eye” counting of some sort, don’t forget that an actual “eye” requires a brain to process information. There is no visual recognition system that sophisticated for the mass market.

Once the eye counter has completed a cycle, there is no way to determine the actual count. If two parts are counted as one, if the eye efficiency has declined from improper set-up or “sight” obstruction, if scrap parts are counted, if parts miss the container, the only quality control possible is visual re-inspection and check weighing.  While this is also technically true for an escapement counter, the design can allow 100% accuracy without verification except in cases of scrap, partials or irregular shapes.

Our systems will give you the confidence you need in your purchase speed, accuracy and verification.
