The roller top stacker includes a roller top assembly mounted to the boom assembly and a drive system for raising roller top assembly between a raised and lowered position. The roller top assembly has a top surface comprising a pattern of openings through which rollerballs protrude when in a raised position and in a lowered position which the rollerballs do not protrude.

Various embodiments provide a material handling vehicle (MHV) and associated method provide for damping of mast oscillations of a mast of the MHV. In one approach, mast oscillations can be detected and/or anticipated and a countering force can be generated by an elevated reach actuator of the MHV to damp the oscillations.

A transport device for transporting a cryopump includes a bogie that includes a front wheel and a rear wheel, a mast that extends from a front side of the bogie in a height direction, a raising and lowering unit that is supported by the mast and that has a changeable height, a guide rail that extends forward from the raising and lowering unit, an arm that is supported by the guide rail and that is slidable in a front-rear direction, a cargo platform that is provided at a tip part of the arm and that holds the cryopump, and a counterweight that is provided on a rear side of the bogie.

The disclosure relates to a method for controlling a warehouse robot to store and fetch inventory materials. The method includes: instructing a material handling device to fetch a second inventory material located in the front row, and placing the second inventory material on a first tray; instructing the material handling device to fetch a first inventory material located in the back row, and placing the first inventory material on a second tray; and instructing the material handling device to return the second inventory material to the front row. By instructing the material handling device to fetch the inventory materials and storing the inventory materials in the trays, the inventory materials can be extracted from a designated shelf and stored in a warehouse, navigation is realized in a crowded warehouse filled with obstacles, and the inventory materials whose positions have been transferred can be processed.

A transferring robot is disclosed in the disclosure. The transferring robot includes a movable chassis configured to move along a path among adjacent warehouse storage containers; a temporary storage shelf provided on the movable chassis, the temporary storage shelf being configured to store a target case; a fetching assembly provided on the movable chassis, the fetching assembly being configured to extend or retract horizontally relative to the movable chassis, so as to realize fetching and placing of the target case between the storage containers and the temporary storage shelf, where a direction along which the fetching assembly extends or retracts horizontally is perpendicular to a moving direction. A warehousing and logistics system includes the foregoing transferring robot. The disclosure further discloses a warehousing system and an item transferring method.

A controlling device of a forklift executes a stopping process of stopping lowering of a fork by a lift device when a detection sensor is separated from a first facing surface while the fork is being lowered by the lift device in a placing operation, a forward tilting process executed after execution of the stopping process, the forward tilting process controlling the tilt device to tilt the fork forward until the tilt angle reaches a limit value, and a returning process of sequentially obtaining values of the tilt angle during execution of the forward tilting process and tilting the fork rearward when the value of the tilt angle stops changing before the tilt angle reaches the limit value. The returning process is not executed in a case in which the tilt angle reaches the limit value.

A transferring robot is disclosed in the disclosure. The transferring robot includes a movable chassis configured to move along a path among adjacent warehouse storage containers; a temporary storage shelf provided on the movable chassis, the temporary storage shelf being configured to store a target case; a fetching assembly provided on the movable chassis, the fetching assembly being configured to extend or retract horizontally relative to the movable chassis, so as to realize fetching and placing of the target case between the storage containers and the temporary storage shelf, where a direction along which the fetching assembly extends or retracts horizontally is perpendicular to a moving direction. A warehousing and logistics system includes the foregoing transferring robot. The disclosure further discloses a warehousing system and an item transferring method.

A method for controlling a warehouse robot to store or retrieve an inventory item on a shelf. The method includes: receiving an instruction to transport the inventory item, obtaining a position of the inventory item from the received instruction, directing the warehouse robot to move to the location of the inventory item, detecting a position shift of the inventory item away from the obtained position based on the location and the orientation of the inventory item, adjusting a position of the warehouse robot to compensate for the position shift, retrieving the inventory item from storage, and transporting the inventory item to a destination.

This application provides a robot and a warehousing system. The robot is configured to take or place a goods container which includes a robot body and a fork apparatus. The fork apparatus is arranged on the robot body which includes a telescopic mechanism and a goods retrieval mechanism. The telescopic mechanism includes a base plate and a transmission assembly. The goods retrieval mechanism is connected to the transmission assembly to move along a length direction of the base plate under the drive of the transmission assembly. The goods retrieval mechanism includes a rotating unit, a connecting base, and a goods retrieval unit. The goods retrieval unit is arranged on the connecting base. The rotating unit is configured to drive the connecting base to rotate relative to the telescopic mechanism, so that the goods retrieval unit can take or place the goods container in a different direction of the fork apparatus.

A carrier applying precision support and lifting by an Automated Guided Vehicle includes a frame, two supporting arms, and pressing components. Two supporting arms are located on either side of the frame and are movable in a receiving direction relative to the frame. The pressing components are located on the frame, the pressing components include first pressure balls, for pushing the supporting arms across the carrier, and second pressure balls for pushing the supporting arms along the receiving direction. The first and second balls improve the positioning accuracy of the supporting arms relative to the object or material to be transported and reduces friction between the supporting arms and the pressing components. An AGV cart and a loading system are also disclosed.
