Abstract
An improved transition section for a bag filling device is disclosed for use with a bag filling machine. The device comprises a new and novel transition structure that may be utilized to effectively absorb the energy of the material passing through the filling machine and to effectively control the flow of the material in the transition section so that at least two flow paths are formed within the transition chute throat section with one flow path being utilized for downwardly flow of the material being filled in the bag filling machine and the other flow path being utilized for upwardly flow of dust and air resulting from the filling process. The dual flow paths are formed by a rigid divider member fixedly attached to the control device suspended in the transition chute with the divider member moving in a generally horizontal direction in an arcuate path. The improved structure also comprises means for stopping the movement of the divider member at a predetermined position so that the path utilized for upward air flow always remains open regardless of the position of the divider and the improved structure further comprises means for removing the upwardly flowing air and dust from the transition chute. Also disclosed is a new and novel method of controlling the amount of dust in a transition section of a material packaging line whereby the dust created by the impact of the falling materials can be effectively controlled in the upper portion of the transition chute where it can be readily removed.
