Vision inspection system for double stacked packs

摘要

An apparatus and process for the inspection, conveying, and optionally temporary storage of uniform packaged goods is described. The apparatus includes a singulating device which takes dual stacked goods and reduces the dual stack to a single line of goods, inspects the goods, returns the goods to a dual stack, and transports them to a cartoner. A preferred embodiment contains a temporary buffer for storage of the goods to compensate for manufacturing speed changes, supply/demand fluctuations, or excessive rejects.
