Poka Yoke

Poka yoke means “fool-proof” or “mistake-proofing” avoiding inadvertent human errors, or a method of preventing errors by putting limits on how operation can be performed in order to force the correct completion of the operation.

Pharmaceutical Tracking

One example of the poka yoke process is the first stage of the pharmaceutical industry: primary filling line. Unlabeled bottles are filled with prescriptions on this line. An inkjet prints 2D Matrix Code onto the bottle and our machine vision system reads, records and archives. The archived data contains all critical information on that prescription. These now filled bottles are then sent to a warehouse.

When an order comes in, the required unlabeled bottles are brought to the secondary labeling line. A different AISI system reads each code and sends information to a labeling system which correctly labels each prescription bottle. The records are then updated into a database, allowing both manufacturer and consumer access to know every location this prescription is going to and coming from.
