  • Patent number: 12630362
    Abstract: Systems and methods are disclosed for a shuttle sortation system having a calibration shuttle for determining and adjusting shuttle coordinates for depositing items and/or loading totes at various tote receiving areas. The shuttle sortation system may include item tracks and tote tracks for sorting and/or distributing items, packages, and/or totes, and may move the shuttles about the shuttle sortation system via linear synchronous motors (LSMs). The calibration shuttle may include a base portion designed to interface with the track (e.g., with the LSMs). The base may support imaging systems having cameras and processors for capturing images of the tote receiving areas and processing the images to determine a centerline of such tote receiving areas and adjusting coordinates used to navigate the shuttle to the tote receiving areas. The calibration shuttle may be navigated to each tote receiving area to adjust coordinates where an offset from the centerline is detected.

  • Patent number: 12617613
    Abstract: Systems and methods are disclosed for a shuttle track system for efficiently sorting items and packages by increasing a throughput of shuttles loaded with items. To increase item shuttle throughput, a shuttle track designated for shuttles that transport items (e.g., item track) may be positioned between on either side of a tote track designed for shuttles that transport totes (e.g., tote tracks). Tote receiving areas which may support totes for receiving the items may be positioned between each item track and the tote track. Shuttles designed to transport items (e.g., item shuttles) may deliver items to the totes in the tote receiving areas via the item tracks and shuttles designed to retrieve and/or receive totes (e.g., tote shuttles) may retrieve and/or receive totes via the tote track. Multiple sortation levels may be stacked and interconnected via ramps and/or shuttle lift systems to maximize and/or optimize item shuttle throughput.

  • Patent number: 12205320
    Abstract: Systems and methods are disclosed for a shuttle track system having a calibration shuttle for determining portions of the track having non-conforming geometry for optimum use of the shuttle track system. For example, the shuttle track system may include a track having an electromagnetic propulsion system (e.g., linear synchronous motor) embedded between two sides of the track. The calibration shuttle may move to various locations on the track and may use imaging systems for generating image data of a portion of the track. A trained model may process the image data to determine edges and surfaces of the components of the track and may determine distances between reference points on the track. The distances may be compared to threshold values to determine if they are in conformity with desired track geometry.
