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.

A sand spreader includes a sand storage chamber. Two sand discharge ports are disposed below the sand storage chamber, and are an upper-layer staggered sand discharge port and a lower-layer sand pressing plate sand discharge port, respectively. The upper-layer staggered sand discharge port comprises a left side sand discharge plate and a right side sand discharge plate configured to intersect with each other. Horizontal staggered ports are formed in a position at the bottom of the two sand discharge plates, and vertical spacing between the staggered ports is adjustable. Also comprised is the lower-layer sand pressing plate sand discharge port, including left and right side sand pressing plates. Vertical sand discharge ports are disposed between the sand pressing plates on the two sides, and the width of the vertical sand discharge ports is adjustable, so as to further facilitate control over the amount of discharged sand.

A train bulk cargo loading system having a disconnected railroad track scale, includes a disconnected railroad track scale (1), a tractor (2), a lifting scraping plow (4), a controllable vibration charging hopper (6), a surge bin (8), a belt conveyor (9) and a control terminal (7). The train bulk cargo loading system having the disconnected railroad track scale has a low overall height and a small footprint, thus reducing the construction and production costs. The system integrates loading, trimming, measuring and data sharing, and features uniform loading, balanced train wheel pressure, and accurate measuring. Thus, huge human and material resources consumption caused by uneven loading of an original loading system, large wheel pressure deviation and secondary trimming and measuring required by the railway department may be avoided, significantly reducing the construction cost and operation cost.

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 robot comprises a memory, a processor, a body and a drive system which are coupled. The drive system comprises one of auger-based surface interface portions and continuous tread surface interface portions. The auger-based surface interface portions and the continuous tread surface interface portions are interchangeable to adapt the robot to one of different operating conditions and different uses. The processor is configured to: control movement of the robot, via the drive system, to traverse across a first surface, wherein the first surface comprises piled granular material, in response to the drive system being configured with the auger-based surface interface portions; and control movement of the robot via the drive system to traverse across a second surface, which is a solid or semi-solid surface other than the piled granular material, in response to the drive system being configured with the continuous tread surface interface portions.

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.
