Foreign bodies are the most common cause of complaint and prosecution for manufacturers of all products. The accidental inclusion of unwanted debris can result in problems such as breakdown of supply chain partnerships, claims for financial compensation and loss of consumer confidence. Manufacturers must ensure that they are complying with the best available practice.
Eliminating foreign body contamination prior to filling is vital. Even the best managed preventative systems can fail, so technologies that reliably and rapidly detect unwanted foreign bodies are essential in order to deliver a safe product to the consumer.
Damaged Container Rim
Downtime due to a defective container entering the filling cycle can cost valuable time and could lead to expensive capital equipment damage if left unchecked.
The design team at PLF has introduced a fully automated detection system for containers with damaged rim/out of round or which can detect unwanted particulates utilising a camera system integrated with an intelligent, high speed reject system.
The orientated, empty cans pass along the conveyor, where they are equally pitched for passing under a camera inspection station. A vision camera compares the image it sees with that stored in its memory. Any containers that do not match the stored image (whether for particulate presence or out of shape/damage) are rejected for further inspection.
