ABSTRACT:
An improved weighing hopper for use with a transition chute in a weighing scale of a packaging machine system is disclosed which provides for better control of the flowable materials in the weighing hopper and the transition chute and comprises forming the bottom surface of at least one weigh hopper and the transition chute into which the weigh hopper dumps its material with a slope that is equal to or greater than an angle of repose of the materials being handled in the weighing hopper. The use of the angle of repose or greater in combination with a controlled opening of the weigh hopper doors aids in controlling the flow of material and minimizes dust generation. Also disclosed are other related improvements to the weighing hopper which comprises positioning the weighing hopper and the transition chute in close proximity to each other and to the throat of the transition section for the purpose of minimizing the generation of dust within the weighing hopper by controlling the distance the material has to flow. A further related disclosure is contained for use with an improved weighing hopper for the purpose of control of suspended dust within the weighing hopper which comprises providing the transition chute with a vertically movable elongated divider member which may be positioned within the transition chute with the divider member providing a means for escape of entrapped air and dust as the bag is being filled. The various related improvements to the weighing hopper may be utilized singly or combined together to provide a much improved weighing hopper for use with a weighing scale of a packaging machine, and there is also disclosed various methods for controlling and collecting dust in the weighing hopper transition chute.
