A system for replenishing a pick face includes a storage and retrieval machine (SRM) that traverses an aisle of a warehouse and monitors a replenishment position of each pick location of a pick face. The SRM transmits a message to the system indicating which ones of the replenishment positions are empty. The SRM delivers a replenishment load to a pick location that is indicated as empty in the message. Each pick location includes a flow lane configured to direct the motion of package loads sliding down to a picking position of the pick face. The flow lane includes a lever arm assembly that constrains and brakes the motion of package loads sliding down the flow lane. A bar stop of the lever arm assembly constrains a replenishment load, while a retainer bar of the lever arm assembly constrains a forward load. The replenishment load is behind the forward load.

A load handling system and method of handling a load includes a load handling device with a load support that is configured for engaging a load and a first drive is adapted to drive said load support with respect to a load. A conveyor is moveable along the load support and a second drive is adapted to propel the conveyor with respect to the load support. The first and second drives are operated to handle a load. The load support may be a pair of forks or a platen or the like.

Load handling system and method

An automated guided vehicle for carrying a load comprises a mast, a lift carriage, a ball screw drive assembly and a ball screw joint. The ball screw drive assembly has a lift nut and a vertically oriented ball screw. The ball screw joint operatively couples the drive assembly to the lift carriage so as to transmit upward vertical forces from the drive assembly to the lift carriage. The ball screw joint includes first, second, third and fourth shafts which permit the lift nut to move in any horizontal direction and to pivot about any horizontal axis with respect to the lift carriage. As a result, the ball screw joint advantageously prevents the transmission of horizontal forces and angular moments between the ball screw and the lift nut, thereby reducing the wearing out effects of component misalignment on the ball screw assembly.
