A method and apparatus is disclosed for use in weighing products having circular or oval footprint or an outwardly projecting flange. A conveyor having a pair of parallel conveyor elements arranged to underengage the footprint or flange only adjacent the periphery thereof transports the products one at a time across a weigh pan or scale device, whose length in the direction of conveyor movement is selected as the lowest value required to achieve a desired settle time for the weigh pan. Preferably, the length of the weigh pan is chosen to be essentially equal to the diameter of products to be weighed.

Checkweigher which weighs product suspended by flange

A flow directing conveyor mechanism includes a lower conveyor defining an article supporting surface for transporting articles for movement along a path of travel extending between inlet and discharge ends of the lower conveyor; and an upper conveyor having pushing mechanisms for displacing articles, while supported by the surface, transversely of the path of travel, as an incident to movement of the articles between the inlet and discharge ends.

Convergent/divergent product conveyor

A method and apparatus is disclosed for use in weighing products having circular or oval footprint configuration. A conveyor having a pair of parallel conveyor elements arranged to underengage the footprint only adjacent the periphery thereof transports the products one at a time across a weigh pan or scale device, whose length in the direction of conveyor movement is selected as the lowest value required to achieve a desired settle time for the weigh pan. Preferably, the length of the weigh pan is chosen to be essentially equal to the diameter of products to be weighed.
