Q: How do checkweighers reject non-compliant products?

A:

In modern automated inspection and rejection systems, every product is weighed on an in-line checkweigher as it travels. Once weight falls outside the set tolerance, the checkweigher reject system engages. Lightweight items are diverted with a pneumatic rejection system (air jet), while heavier ones may be pushed off by actuated arms or gates. Fragile or sticky items drop gently via flaps or belts. This conveyor-based inspection and rejection system ensures real-time quality control, maintaining flow speed and minimizing product loss—a vital feature of contemporary conveyor reject system implementations
