Machine Vision Inspection of Pouch Seal Areas

摘要

This project developed and demonstrated a multi-camera, full production, machine vision pouch seal area inspection system which was installed on a Multivac horizontal form-fill-seal line located at the CORANET DEMO site. In addition to the inspection system, an automatic reject mechanism was designed and implemented. The vision system inspects the sealing area of the filled, formed, pouch bottoms for contamination that may cause seal defects. The entire area of contamination is calculated from the camera images. Pouches with seal areas that exceed threshold levels of contamination are rejected via an integrated control system that signals a reject mechanism to pick up and reject the potential defective pouch into a reject bin once the pouch exits the Multivac horizontal form-fill-seal line.
