A combination of off-the-shelf hardware and software allows plastic containers to be inspected consistently.
Today," says Nello Zuech, president of Vision Systems International, "numerous machine-vision systems are available that address the needs of container and filler manufacturers. Systems can monitor finished glass containers to eliminate any reject conditions that may occur due to errors in regions such as the sidewall and neck. In the case of plastic bottles, systems can be deployed to inspect a product's dimensions, thread presence, finish, neck, sidewall, and heel properties. As with glass, filled plastic bottles can also be inspected for fill height, label presence, correctness, and registration, as well as cap presence."
