The cantilever assembly comprises a first bracket assembly and a first conveyor, the first bracket assembly being mounted to the base assembly; and the first conveyor being mounted to the first bracket assembly. The conveying assembly comprises a second bracket assembly, a second conveyor and a suction cup assembly, the second bracket assembly being mounted to the first bracket assembly, the second conveyor being mounted to the second bracket assembly, and the suction cup assembly being rotatably mounted to the second bracket assembly; and the suction cup assembly being configured to adsorb an article to the second conveyor.

Abstract: A transportation system, including: a transportation vehicle, multiple layers of rail structures, and a layer-switching lifting structure. The transportation vehicle is configured to transport an article. Each layer of rail structure of the multiple layers of rail structures includes a transverse rail and a longitudinal rail, and the transportation vehicle is configured to move in a storage region along each layer of rail structure to transport the article. The layer-switching lifting structure is arranged at a target position of each layer of rail structure, wherein the target position includes an intersection of the transverse rail and the longitudinal rail. The layer-switching lifting structure is configured to transfer the transportation vehicle between the multiple layers of rail structures, and the layer-switching lifting structure is further configured as a carrier for the transportation vehicle to change between the transverse rail and the longitudinal rail.

Abstract: The present disclosure relates to a warehouse shuttle. The warehouse shuttle comprises: a vehicle body; a first arm mounted to the vehicle body; a second arm mounted to the vehicle body and arranged spaced apart from the first arm; a first carrying member arranged between the first arm and the second arm to carry articles between the first arm and the second arm; a first flexible drive part comprising a first flexible transmission member, the first flexible transmission member being connected to the second arm to cause the second arm to move relative to the first arm; and a second flexible drive part comprising a second flexible transmission member, the second flexible transmission member being connected to the first carrying member to cause the first carrying member to move relative to the first arm.

Abstract: A method and system for controlling message transmission for a communication group are disclosed. While a message-on-hold mode remains activated for a first communication group at a first client device: the device, in response to detecting a change in the usage of the first client device: in accordance with a determination that communication suspension criteria are met with respect to the first communication group, prevents transmission of communications in the first communication group to the first client device; and in accordance with a determination that communication resumption criteria are met with respect to the first communication group, temporarily enables transmission of communications in the first communication group to the first client device without deactivating the message-on-hold mode for the first communication group.

Abstract: Provided is a sorting device, comprising a guide rail and a material vehicle moving on the guide rail. A plurality of sorting ports are disposed on both sides of the guide rail, and at least one electromagnet is disposed at a position of the guide rail corresponding to a sorting port; the material vehicle includes a vehicle frame, a tray, at least one magnet and at least two elastically telescopic pieces; the vehicle frame is used to bear the tray, and the tray is rotatably connected to the vehicle frame; the magnet is disposed on a surface of the tray opposite to the material loading surface, and the magnet is connected to the electromagnet in an attraction way, and the elastically telescopic pieces and the tray, for maintaining the transportation state or resetting the tray after the unloading state.
