Devices, systems, and methods for autonomously packing unfolded laundry articles into a container are described. The system includes a container configured to receive the laundry articles, a movable surface for receiving the container, and at least one drive motor for imparting motion to the laundry articles in the container, including at least one of a shaking, twisting, vibrating, oscillating, shushling, and tilting. At least one sensor is configured to detect two or more container fill heights. A controller in communication with the at least one drive motor and the at least one sensor is configured to instruct the at least one drive motor to rotate at least one of a driven conveyor, driven pusher, and driven rollers and the container disposed thereon rapidly back and forth repeatedly until a maximum height variation in the two or more container fill heights falls within a threshold range.

A system for profiling particulate material in an open top conveyance comprises a profiling structure supported above the open top conveyance and engaging the particulate matter in the open top conveyance as the open top conveyance moves in a forward direction therebelow so that the particulate matter forward of the profiling structure is given a generally uniform profile in at least a longitudinal middle portion of the open top conveyance. The open top conveyance normally is one of a sequential train of gondola cars moving on a pair of rails extending under the profiling structure, and the particulate material typically is or comprises coal.
