An inventory management system can include a workspace defining a plurality of loading zones separated by passages and each sized to contain a palletized item stack. A carriage suspended over the workspace may move above the loading zones. An accessory may be coupled with the carriage and extend at least partially downward into the passages. The accessory can include a main body; a boom extending at least partially upward from the main body toward the carriage; a dispenser coupled with the main body and arranged for supporting a spool of stretch wrap material; and a driving wheel extending from the main body. The driving wheel may rotate against the target palletized item stack and propel the main body and the boom within the passages and along a perimeter of the target palletized item stack so that stretch wrap material is deployed around the target palletized item stack.

A delivery system generates a pick sheet containing a plurality of SKUs based upon an order. A loaded pallet is imaged to identify the SKUs on the loaded pallet, which are compared to the order prior to the loaded pallet leaving the distribution center. The loaded pallet may be imaged while being wrapped with stretch wrap. At the point of delivery, the loaded pallet may be imaged again and analyzed to compare with the pick sheet.

An apparatus and method for stretch wrapping of a palletized load uses film tension feedback derived from a film tension control load cell to control film dispensation. The load cell measures film tension and the film payout rates is determined by the film tension. Film tension values are used to determine when an out of bounds condition occurs, namely, when a film break has occurred, or when a possible film break is about to occur or when the film has been cut at the end of a wrapping cycle. To prevent film free end entanglement caused by a break, clamps engage the film so the film tail is controlled, eliminating the risk of recoil. The broken film tail may then be quickly and reliably reattached to the rotating load in a desired position.
