To prepare for the demands of the future, Kaufland (part of Schwarz Group) has equipped its Logistics Centre in Germany with a new Vanderlande order fulfilment system for the smaller, slow-moving products in its product range. The project partners focused on the entire goods flow in the warehouse process.
Kaufland was confronted with a dramatic increase in product diversity and a significant rise in sales of smaller, slow-moving products, while overall turnover had remained the same. The quality of the outer packaging had significantly worsened. They found themselves facing the daunting challenge of finding a cost-effective and efficient order fulfilment system with ergonomically designed workstations. In close cooperation with the client, Vanderlande developed the solution: An AS/RS for pallets and totes, combined with a ‘goods-to-man’ order picking system.
One of the project’s objectives was to manage storage and order fulfilment of up to 8,000 different products from 16 product families on 7,500m2 floor space, without sacrificing floor space in Receiving and Despatch.
In Receiving a 2-aisle pallet AS/RS (2,052 locations) takes care of replenishment. Pallets are presented to the operators at an ergonomic height at six repacking stations. They remove the required items and place them in product totes based on instructions they receive from SAP LES/TRM. Product totes are stored in a 20-aisle miniload AS/RS. For order picking the totes are retrieved on an individual order basis and transported to one of the twelve order picking workstations. The order picker takes the number of items indicated on the SAP LES/TRM screen from the product tote and places them in an order/shipping tote. Order picking performance exceeds 320 items per hour. After picking, the order totes are labelled and stored in a buffer. They are released for delivery on demand at exactly the right time, in exactly the right sequence, ensuring optimum sequencing of forklift truck traffic to the Despatch area. Three of these order totes can be stacked on top of each other in the delivery truck. Two such stacks have the same footprint as a Euro pallet, so that the available floor space in the truck can be used significantly more efficiently. Handling in the retail outlets is also much easier for staff.
Vanderlande was selected because it proposed the most efficient, reliable solution, making excellent use of the available space, creating high storage density and high order picking performance. Before system design started, a detailed study was done of the handling processes at each workstation. The results of this study led to process improvements and resulted in ergonomically designed workstations. High repacking and order picking performance has been achieved in combination with improved order picking quality. Kaufland also benefits from lower transport costs. Because orders are picked directly into order totes, the floor space in the delivery trucks is used much more efficiently. As a result, fewer vehicles are required to make the deliveries to the retail outlets. This approach has also reduced damage during product handling. The new order totes have also made it easier to replenish store shelves.
The project team succeeded in installing and commissioning the complete system in advance of the agreed date. The defined system availability and performance targets were achieved sooner than had been contractually agreed. From the very start of the project, partnership and collaboration led to positive acceptance of the complete system in all areas throughout the entire process.
