Premium Waters, Inc. of Minneapolis, MN, a leader in the private label bottled water industry, faced the challenge of meeting increasing demand and throughput. They needed a solution that could handle high throughput rates and provide efficient storage configuration. Initially considering a pallet flow system, they ultimately chose an Automated Storage and Retrieval Systems (AS/RS) and Savanna.NET® Warehouse Management System (WMS) from Westfalia Technologies, Inc. The new system was installed at their Douglas, GA plant to convey products from palletizing, through high-density storage, to outbound staging lanes on the shipping dock. The AS/RS includes two Storage/Retrieval Machines (S/RMs) operating in one aisle, each capable of handling two pallets at a time, which is a key advantage of Westfalia’s flexible high-density warehouse designs.

To handle peak production and order selection times, Premium Waters installed Air Chain Accumulation Conveyors at both the infeed and discharge of the AS/RS. These conveyors provide a buffer for smoothing peak operations and cut the average S/RM travel distance. Pallets of bottled water are sent from production either into the AS/RS or directly to the shipping dock via Westfalia’s unique Drawbridge Conveyor. The Drawbridge Conveyor either lays across the crane aisle for pallets to travel directly to the shipping dock or lifts straight up for the S/RM to move through the aisle. Once pallets are stretch-wrapped and labeled, they enter the automated system. Each pallet is conveyed to a squaring station, where it is centered on the conveyor, profile checked, and scanned for identification. If a pallet load is outside the predefined load envelope or can’t be scanned, it will be rejected and require forklift removal and correction. Pallets that pass the profile check and scanning station are conveyed to the infeed of either S/RM 1 or S/RM 2 and are placed in the storage rack as directed by Westfalia’s Savanna.NET® Warehouse Management System.

When selected for shipping, Savanna.NET directs the movement of the pallet out of the racks via the Satellite and S/RM, and onto discharge Air Chain Accumulation Conveyors. The pallets discharge position is such that forklift trucks may pick them up by either the 48” or 40” pallet face. Westfalia’s Savanna.NET accurately tracks the inventory and FIFO product shipments.
Premium Waters selected Savanna.NET’s basic functions, including the management of all SKUs, pallets, and storage lanes in the system, as well as the Warehouse Control System component which controls all the automation devices. The system also includes user management grouping and the scheduling of periodic tasks, such as re-warehousing pallets, pick lane replenishment, and data clean-up.
Expansions to the basic Savanna.NET for Premium Waters include an extension to track and control outbound orders, even linking manual movements within the facility. This means all goods moved manually throughout the facility, including via forklift trucks and pallet jacks, are tracked in Savanna.NET.
