Abstract: A computerized scale in which each weighing bucket is formed by two side-by-side compartments and by a single door which shuttles back and forth between two positions beneath the compartments. Each time the door changes positions, it closes one compartment to permit product to be dropped into and weighed in such compartment and, at the same time, opens the other compartment to permit previously weighed product to fall therefrom. As a result, one compartment is filled as the other compartment is being emptied so as to significantly increase the cycle rate of the scale.
Abstract: A combinatorial weighing apparatus in which an operator manually supplies a combinatorial weighing apparatus with articles to be weighed is provided with hopper sets each of which has two weighing hoppers and a single movable pool hopper for supplying the articles to the two weighing hopper in the hopper set. An article supply table is capable of being swung open by virtue of a hinge mechanism, and a plate constituting the top of the supply table is capable of being removed. This arrangement allows detachable pool hoppers and weighing hoppers to be easily removed from the combinatorial weighing apparatus.
