  • Publication number: 20230119061
    Abstract: A dynamic storage wall with reconfigurable storage cubbies and methods of operating the storage wall are provided for a storage facility. The storage wall includes a shelf with multiple storage cubbies and one or more repositionable dividers defining boundaries between the cubbies. The storage wall includes a Time of Flight (ToF) sensor array adjacent to the shelf for measuring positions of each of the repositionable dividers. The ToF is also adapted for recognizing when an item has been retrieved from or placed at either of said storage locations. A workflow control system with a computer is connected to the sensor array. The control system utilizes data from the ToF sensor array to determine when a repositionable divider has been moved and/or when an item has been retrieved from a storage location. The system may automatically or manually recognize when a divider is moved and that new measurement is required.

  • Publication number: 20230056919
    Abstract: A time tracking and indicator system and method are provided for tracking and indicating initialization-to-completion times for order fulfilment operations, such as order packaging and shipping operations. The system includes a put-wall with multiple order storage locations and indicators at each of the storage locations. The indicators are independently addressable by a computer and may include color changeable lights and/or alphanumeric displays. The method and system provide visual prompts to an operator of the put-wall to indicate multiple statuses for an order at a particular storage location. Prompts include indications that (i) an order is ready to be attended to, (ii) an operation time limit has been exceeded, and (iii) that an operation for that location is exceedingly overdue. Time limits and prompts may be preset by a user or may be automatically set and adjusted by the computer based on historic operation completion times.
