  • Patent number: 11851218
    Abstract: A material handling apparatus for reorienting and transferring inventory items to a packaging device includes a support member and a packaging conveyor. The support member receives an inventory item and reorients the item to a rejection orientation or a packaging orientation. The item is moved onto the packaging conveyor in the packaging orientation and is transported to the packaging device.

  • Patent number: 11358793
    Abstract: In one embodiment, an inventory storage module has a plurality of conveyor segments that define a movement path that is elongate along a longitudinal direction from a first end of the storage to a second end of the module. The module has a plurality of container carriers that are supported by the conveyor segments. Each container carrier supports at least one inventory storage container that supports at least one inventory item therein. The storage module can transfer the container carriers around the movement path until a desired one of the container carriers is presented at one of the first and second module ends. In another embodiment, a plurality of instances of the storage module are arranged in a vertical stack of independently controllable storage modules.

  • Patent number: 10815082
    Abstract: In one embodiment, an inventory storage module has a first conveyor segment, a second conveyor segment spaced below the first conveyor segment, a first vertical lift disposed at a first end of the module, and a second vertical lift disposed at a second end of the module. The first and second lifts each transfer inventory carriers between the first and second conveyor segments. The first conveyor segment, the second conveyor segment, the first vertical lift, and the second vertical lift together define a conveying loop in a vertical plane, and the storage module translates inventory carriers around the conveying loop until a desired one of the inventory carriers is presented at one of the first and second module ends. An inventory item can be retrieved from, or stowed in, the desired one of the inventory carriers at the one of the first and second module ends.

  • Patent number: 10807798
    Abstract: In one embodiment, an inventory storage module has first to fourth conveyor segments that define a conveying loop. The module translates storage totes around the conveying loop using, at least in part, first and second actuator assemblies. The first actuator assembly has a first actuator and a first crossbar connected to the first actuator. The first actuator assembly moves the first crossbar in a first direction such that the first crossbar engages and pushes totes along the first conveyor segment in the first direction. The second actuator assembly has a second actuator and a second crossbar connected to the second actuator. The second actuator assembly moves the second crossbar in a second direction, opposite the first direction, such that the second crossbar engages and pushes totes along the second segment in the second direction. The third and fourth segments transfer totes between the first and second segments.

  • Patent number: 10735991
    Abstract: Embodiments herein describe wireless transmission techniques for mitigating interference between wirelessly controlled machines in a shared space. To mitigate interference, the machines may be assigned different channels within the same frequency band. However, if machines using the same channel in a frequency band receive each other's wireless signals, the wireless signals can interfere. To free up additional bandwidth, in one embodiment, the command signals are transmitted using a different frequency band than a heartbeat signal used to stop the machines in case of emergencies. In another embodiment, time multiplexing or directional antennas can be used to mitigate interference. In another example, antenna diversity and multiple-input-multiple output (MIMO) can be used to further focus the radiation pattern onto the desired machine while avoiding transmitting wireless signals to neighboring machines. In one embodiment, the machines may use dual-channels to transmit and receive duplicate data.

  • Patent number: 10639800
    Abstract: In one embodiment, an end effector for a robotic manipulator has a base that is configured to attach to the end of a robotic arm, a first fork, and a second fork. The end first fork includes a first pair of prongs that extend from the base along a first direction and that are spaced from one another so as to receive a first storage container therebetween. The second fork includes a second pair of prongs that extend from the base along a second direction that is angularly offset from the first direction and that are spaced from one another so as to receive a second storage container therebetween. The first and second forks can be used to stack or unstack the first and second containers.

  • Patent number: 10196208
    Abstract: In one embodiment, an inventory storage module has first to fourth conveyor segments that define a closed conveying loop in a horizontal plane. The storage module can translate inventory carriers around the closed loop until a desired one of the inventory carriers is presented at one end of the module. The first conveyor segment translates inventory carriers along a first longitudinal direction. The second conveyor segment is offset from the first segment along a first lateral direction and translates inventory carriers along a second longitudinal direction, opposite the first longitudinal direction. The third conveyor segment translates inventory carriers from the first conveyor to the second segment along a first lateral direction at a second end of the module. The fourth conveyor segment translates inventory carriers from the second segment to the first segment along a second lateral direction, opposite the first lateral direction, at a first end of the module.
