  • Publication number: 20260035119
    Abstract: A system for filling containers with loose items can include a container conveyor configured to move containers to a container filling location, an item conveyor having a downstream end disposed above the container conveyor at the container filling location, one or more sensors configured to detect the items moving on the item conveyor, and one or more processors in communication with the container conveyor and the one or more sensors. The one or more processors can be configured with computer-executable instructions to receive signals from the one or more sensors and to control a speed of the container conveyor based on the signals received from the one or more sensors.

  • Publication number: 20250326589
    Abstract: Systems and methods capable of transferring items from a bin are described. A de-binning system includes an item transfer apparatus including a transfer conveyor configured to move a conveyor belt surface, and a bin sub-frame coupled to the transfer conveyor and configured to receive a bin. While an item-containing bin is secured to the bin sub-frame, the bin sub-frame and the transfer conveyor are inverted to transfer the items onto the transfer conveyor, which can move the items onto a second conveyor belt. Various aspects of the present systems and methods prevent damage to the surface of delicate items being transferred.

  • Publication number: 20050208451
    Abstract: The present invention provides a utility line extension and retraction system for enabling users thereof to selectively extend a utility line for utility line use and retract the utility line for utility line storage. The utility line extension and retraction system essentially comprises a plurality of utility line cassettes. Each utility line cassette essentially comprises two laterally-spaced, pulley-receiving walls, an anterior line outlet end, a posterior line inlet end, a stationary pulley assembly adjacent the anterior line outlet end; a traveling pulley assembly intermediate the anterior line outlet end and the posterior line inlet end, and a utility line extending from the posterior line inlet end to the anterior line outlet end, which line imparts motion to the traveling pulley assembly. The traveling pulley assembly travels along a closed path comprising an ascension path, a descension path, and an extended-state rest stop intermediate the ascension and descension paths.
