Abstract: In one embodiment, an inventory storage module has a pair of upper tracks and a pair of lower tracks that are connected to one another so as to define a closed movement path in a vertical plane. The module has a plurality of carriers arranged end-to-end along the upper and lower tracks. Each carrier is elongate along a direction that extends between a pair of the upper or lower tracks so as to carry a set of the storage containers that are arranged side-by-side. Each carrier has first and second first wheel assemblies that couple the carrier to the pairs of upper tracks and lower tracks when supported by the pairs of upper tracks and lower tracks, respectively. The storage module can move the inventory carriers around the movement path until a desired one of the inventory carriers is presented at one of the first and second ends.

Abstract: In one embodiment, an storage module has first and second guide rails that are spaced from one another along a lateral direction. Each guiderail has an upper track and a lower track spaced from one another along a vertical direction, and first and second connecting tracks that connect the upper track to the lower track at first and second ends, respectively. A plurality of inventory carriers that are supported between the guiderails and are arranged end-to-end along the upper and lower tracks. A drivetrain drives the carriers to translate along the upper and lower tracks at a first speed, and drives the carriers to translate along the connecting tracks at a second speed, faster than the first speed. Increasing the speed of the carriers at the connecting tracks can prevent the carriers from colliding with one another when transitioning between the upper track and the lower track.
