An automated build-by-layer rainbow pallet system comprises a layer build track and a layer build cart that carries a layer build robot and a number of positions for building rainbow pallets, for storing emptied supply pallets, and for storing empty half-pallets. On the rail-sides are dozens or hundreds of supply pallet conveyors for pallets of products to be picked-from when building the rainbow pallets. These are placed on one or both sides of the layer build track. The layer build robot can position itself in front of the appropriate supply pallet conveyor for picking. Once in position, half or full layers can be picked from the supply pallets and positioned over the target rainbow pallet to be built. The process of picking and building layers as the layer build cart repositions in front of the appropriate supply pallet conveyor is repeated until all of the on-board rainbow pallets have been built. The layer build cart returns to an unloading area where the emptied supply pallets and built rainbow pallets are conveyed off to respective exit conveyors. Several empty pallets are then moved from an empty pallet supply, and placed in the individual rainbow pallet build locations either by robot or conveying. The system is then ready to build more rainbow pallets. The system is controlled by a software program for orchestrating the overall movement and building of pallets.
