Check Weigher

A Check weigher is a system that weighs items as they pass through the unit, classifies the items by preset weight zones, and ejects or sorts the items based on their classification. Check weighers weigh 100% of the items on a production line.

A check weighing system typically has five parts: an in-feed section, weigh section, discharge section, rejecter, and computerized controller.

“In short: a check weigher weighs, classifies, and segregates items by weight.”

Three belts drive the process:

• In-feed belt – brings the product up to weighing speed
• Weigh belt – mounted on a load cell, servo-balance, or split-beam transducer that captures the item’s weight
• Reject conveyor – removes out-of-tolerance packs without slowing the line

Out-of-spec items are removed by a pneumatic pusher, a diverting arm, or a lowering reject belt — typically dropping into a collection bin.
