  • Patent number: 6252181
    Abstract: Method and apparatus for weighing a product being moved by a conveyor. When the product is conveyed to be disposed at a weighing station stationarily positioned relative to the moving conveyor, a weighing platform engages the bottom surface of the product and raises the product upwardly so that the bottom surface of the product is disposed above and spaced apart from the conveyor. After the product is raised above the conveyor, the product is weighed, without any interface with the conveyor, and then lowered back down onto the conveyor. Concurrently, the measured weight of the product is compared to a predetermined weight range. If the weight of the product is properly within a predetermined weight range, the product continues down the production line on the conveyor. If, however, the weight of the product is out of tolerance, the unacceptable product is removed from the conveyor.
