ABSTRACT:
Continuous automatic feeding apparatus for bulk material is provided. The device has a vibratory feeder for moving the material to be fed, the feeder having a centrally disposed narrow spoon extending therefrom which provides a relatively small rate of material feed. A pair of hoppers are located under the composite feeder, and the material supplied to each controlled by a pair of displaceable deflectors. Each deflector has three positions: a first position in which the deflector prevents any flow into its associated hopper and deflects the flow into the other hopper; a second position in which the flow from the feeder is deflected to the other hopper but the flow from the spoon is permitted to enter its associated hopper; and a third position in which the flow from both the vibratory feeder and the spoon enters the associated hopper. Each hopper has a weigh cell and control apparatus associated therewith to operate the deflectors and empty the hoppers when a predetermined weight has been attained.
