Abstract

A vertical bottom-fill auger assembly including a bottom-fill auger bowl containing an internal rotating agitator or wiper element, and a vertical moving carriage or bag handling mechanism including a traveling bag settler. The vertical movement of the carriage or bag handling mechanism may be adjusted in response to the vertical auger revolution rate, the product density or weight as measured by a bulk or net weigh scale attached to the bag support assembly, or to comport to a premeasured charge that is bulk loaded into the auger bowl. The agitator or wiper may be of a configuration having a blade mounted on a rotating shaft vertically disposed in the center of the auger bowl, or may be carried on a rotating ring horizontally disposed at or near the top of the auger bowl. The traveling bag settler includes an arm which may be oscillated in a vertical plane to strike the bottom of a bag being filled, and which travels with the bag as it descends during filling and when lowered to a conveyor. The conveyor is split to form two-spaced apart tracks with the arm of the bag settler being received between the tracks when the bag and bag settler are lowered.
