Stackable inventory storage modules, storage systems, and methods of using the same

Abstract:

In one embodiment, an inventory storage module has a plurality of conveyor segments that define a movement path that is elongate along a longitudinal direction from a first end of the storage to a second end of the module. The module has a plurality of container carriers that are supported by the conveyor segments. Each container carrier supports at least one inventory storage container that supports at least one inventory item therein. The storage module can transfer the container carriers around the movement path until a desired one of the container carriers is presented at one of the first and second module ends. In another embodiment, a plurality of instances of the storage module are arranged in a vertical stack of independently controllable storage modules.
