A portable and articulating conveyor belt device for use with a vehicle having a power supply, wherein the vehicle's power supply powers the conveyor belt device. The conveyor belt device is removably attachable to a trailer hitch assembly on a vehicle, and enables a user to quickly and safely load articles onto/off of the vehicle via a conveyor belt. The conveyor belt device is preferably controlled via a remote control and controls the position of the device, as well as the direction and speed of the conveyor belt. The support frame of the conveyor belt device is comprised of a plurality of repositionable, interlocking and pivoting support frame members that enable the device to be arranged in a variety of configurations to suit user need and/or preference.

A method for loading a container with packages, using a device having at least one guide. At least one hand element is displaceable in the longitudinal direction of the guide, and is provided on the at least one guide. The hand element has a plurality of finger elements. The finger elements have at least two flexible flank elements extending together from one end of the finger element to the opposing end. The at least two flexible flank elements of the finger elements are flexibly connected together via a plurality of webs. The finger elements may be adjusted from at least one curved position into at least one extended position and back. The at least one hand element takes packages one after the other, and deposits the packages into the container in a stack. The hand element is displaced along the guide between the deposit of two successive packages.

A truck unloader for unloading cartons from a carton pile includes a controller with a detection system configured to periodically receive one or more images from a vision system and a processor subsystem in connection with the detection system. The processor subsystem configured to calculate a distance from at least a portion of the truck unloader to the carton pile based on the one or more images and advance the truck unloader to perform a sweeping operation based on the distance in an instance in which the distance satisfies a predefined distance threshold. The processor subsystem further configured to monitor a torque input received as a feedback from the one or more sensors while performing the sweeping operation, wherein the sweeping operation is configured to continue until the torque input exceeds a predefined torque threshold.

A brake roller assembly may comprise: a shaft; a first roller bearing coupled to the shaft and disposed at a first axial end of the shaft a second roller bearing coupled to the shaft and disposed at a second axial end of the shaft; a roller cylinder disposed radially outward of the first roller bearing and the second roller bearing; and a braking arrangement, including a plurality of electrodes, and a plurality of rotor disks coupled to the roller cylinder, each rotor disk in the plurality of rotor disks disposed between an anode in the plurality of electrodes and a cathode in the plurality of electrodes.

A conveying device for converting a serially transported piece goods stream into a parallelly transported piece goods stream. A feed belt conveyor serially feeds the piece goods stream, and a plurality of discharge belt conveyors parallelly discharge the fed piece goods stream. The discharge belt conveyors are assigned to a longitudinal side of the feed belt conveyor. The directions of transport of the discharge belt conveyors are oriented parallel to one another and transversely to the direction of transport of the feed belt conveyor. The discharge belt conveyors are configured as telescopic belt conveyors. The longitudinal side of the upper strand of the feed belt conveyor that is assigned to the discharge belt conveyors is arranged lower than the opposite longitudinal side of the upper strand of the feed belt conveyor.

The present disclosure provides loading and unloading equipment and a package loading and unloading system. The loading and unloading equipment includes: a rack; a marshalling device, configured to receive packages and marshal the packages in a predetermined marshalling mode to form package groups; a pre-storage device, configured to temporarily store the package groups formed by marshalling to be taken away by a stacking device; and the stacking device, configured to remove the package groups from the pre-storage device to stacking positions. By applying the loading and unloading equipment, the loading and unloading efficiency of the packages is improved. The package loading and unloading system of the present disclosure includes the loading and unloading equipment of the present disclosure.

A method for automatic loading of trays into a cart, where the cart is adapted to receive trays at different vertical tray levels, comprises detecting the tray levels with a tray level sensor and lifting the cart with a lifting device from a floor to different vertical positions such that the tray levels in the cart will be at the same vertical level as a loading surface of a conveyer arrangement, which transports the trays to the cart on the loading surface. The method also comprises activating tray stoppers to stop the movement of the trays on the loading surface until the cart is at a correct vertical position, and deactivating the tray stoppers to allow the trays to be loaded into the cart when the cart is at a correct vertical position. The cart is lifted and loaded until all tray levels have been filled, and then the cart is again lowered to the floor. An apparatus for automatic loading of trays into a cart according to the method is also provided.
