An apparatus for conveying root crops is provided. The apparatus includes a carrying device which circulates in a circulation direction during operation. The carrying device partly forms at least one receiving region and carries the root crops. At least one transverse separating device extends at least partially in a transverse direction. This delimits the receiving region in the circulation direction. From the outside, the receiving region adjoins an interior space which extends inside an interior space surface. The interior space surface extends parallel to the transverse direction and in side view runs exclusively in the circulation direction. At least one protruding part of the transverse separating device is arranged, in side view, outside the interior space.

Devices and methods for compaction of an asymmetric load are disclosed herein. In some embodiments, a movable upper structure is connected to a stationary base structure through front end pivot linkages and rear end pivot linkages. One or more actuators impart motion to the upper structure. The motion of the upper structure is controlled by adjusting the length and position of the pivot linkages. In other embodiments, the pivot linkages are attached to a pull arm that is attached to an actuator, and the pull arm imparts motion to the upper structure.

Devices, systems, and methods for autonomously packing unfolded laundry articles into a box are described. The system includes a box configured to receive the laundry articles, a movable surface for receiving the box, and at least one actuator for imparting at least one of a shaking, twisting, vibrating, oscillating, shushling, and tilting motion to the box. A plunger is configured to compress the articles within the box and at least one sensor is configured to detect that the mass of articles is flattened and substantially level across a top surface. A controller in communication with drive motors, actuators, and at least one sensor is configured to determine whether the articles are flattened sufficiently for delivery to a packing station for receipt of folded laundry articles placed atop the plurality of unfolded laundry articles.

The proppants processing system comprises one or more in-feed conveyors, one or more out-feed conveyors, one or more primary feed bin assemblies, one or more secondary bin assemblies, the primary and secondary bin assemblies each comprising one or more bins and one or more bin conveyors. The proppants processing system further comprises a final transport conveyor and a control unit adapted to control flow of the proppants. A method of processing proppants, the method comprising the steps of providing proppants comprising dry or wet sand; using an in-feed conveyor, transferring the proppants from a transport vehicle to one or more bins of a primary feed bin assembly; moving the proppants from the one or more bins to a feed bin conveyor; moving the proppants from the feed bin conveyor to a final transport conveyor; and using the final transport conveyor, moving the proppants to a blender.

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.
