Abstract
A process, apparatus, and associated controls are provided in a system for loading bulk material into a flexible, collapsed container from an overhead storage bin. The container can be positioned on a scale in the loading station. A dicharge conduit from the bin is connected to a discharge spout which is movable into communication with the container. An exhaust conduit from a dust collection system is connected to an exhaust spout which is also movable into communication with the container. The discharge and exhaust spouts are mounted on a carriage movable on a platform toward and away from the container. The platform is movable transversely of the container between a loading position behind the container and a retracted position which accommodates movement of the container therepast. A line is provided for supplying inert gas to the discharge spout. Valves are provided on the exhaust conduit, discharge conduit, and inert gas line for controlling the flows through the conduits. The valves are automatically controlled to inflate the container, to fill the container with the material from the storage bin while exhausting the dust from the container, and to clean out the discharge con…
