Case StudyThe NIKE China Logistics Centre is the sportswear manufacturer’s largest distribution centre in Asia.

The NIKE China Logistics Center (CLC) Taicang, Jiangsu, is the company’s largest distribution center in Asia and handles all shipments of NIKE apparel and footwear for mainland China. The 200,000m2 facility has brought a number of unique operational features to the apparel and footwear industry in China for the first time.

From the outset the center has helped define how large-scale facilities can operate more sustainably, with the main design and specification criteria led by the intent to create a logistics center that brought together a high-performance operation with NIKE’s global commitment to sustainability and the environment.
With an extensive conveyor network, high-tech Crisplant sortation equipment and technologies such as voice picking, the facility is able to operate more efficiently and accurately than a more traditional distribution center, giving NIKE a huge advantage in handling its products in China.

A large part of the energy consumed in a distribution center is used to run the sortation equipment and conveyors, so NIKE was intent on employing the most energy efficient machines available. The company decided on the Crisplant LS-4000 cross-belt and tilt-tray sorters, which use linear synchronous motor technology to reduce energy consumption by 75 percent compared with sorters using conventional technologies. These sorters, plus Crisplant’s state-of-the-art software controls, are helping NIKE achieve a number of its core corporate goals: increased operational efficiency, shippingFinal sorting: Boxes are fed via chutes to the Crisplant LS-4000CB Cross Belt Sorter. flexibility and accuracy, as well as reducing handling costs, energy consumption and the environmental impact of its operations.

Sortation process
The sortation process starts with cartons being unloaded from trucks in the receiving area and then stacked on pallets. The pallets are then moved into the very narrow aisle (VNA) warehouse area.

As required, pallet loads of cartons are selected from the VNA racking and transferred onto a conveyor that merges the cartons onto a line sorter. The line sorter delivers the cartons to three possible destinations depending on whether the goods are to be shipped in batches or made up into new cartons containing a number of different items:

• Whole cartons for onward shipment are delivered to the shipping sorter
• Cartons with items ordered in whole-carton batches go to the pre-sorter induction area
• Cartons containing items that will be collated into mixed-item shipments are sent to the storage

Items unpacked from the cartons are placed into storage racks from which operators pick and place the individual items into plastic totes. The conveyor transports the totes, containing the individual items, to a conveyor on Level 2 of the building.  These totes and whole cartons containing batches of the same item are then merged before beinEmployees place items on the final sorter by hand.g emptied and items are manually placed onto the LS-4000CB cross-belt pre-sorter. This automatically sorts the items in the totes into pre-defined hoppers, which are emptied at the hopper tipping area, from where a system of belt conveyors transports them to manual inductions for loading onto the final sorter.

The final sorter is a second Crisplant LS-4000CB cross-belt sorter, which automatically distributes the individual items into chutes that have been specially designed for the NIKE CLC to reduce the footprint of the sorting area. The chutes feature dividers that rise following the delivery of a complete batch, thereby separating it for packing into a single carton by the operator below. The carton is then pushed onto a roller conveyor for delivery to the Crisplant LS-4000E tilt-tray shipping sorter.

Sorters and controls
All three Crisplant sorters at the NIKE CSC are from the LS-4000 family, a range that is under constant development. Any improvements that are delivered for the LS-4000 standard product will flow down to the cross-belt and tilt-tray models as well.

The LS-4000 sorter system and machine controls are seamlessly integrated with NIKE’s Warehouse Management System.  The ability to combine precise control of individual machines, with system-wide visibility of workflows, enables continual optimization of the system and the avoidance of bottlenecks for faster throughput and higher pA transparent workflow encompassing the entire system ensures precise control of each machine.roductivity.

The future
To ensure maximum operational security, NIKE entered into a three-year service agreement with Crisplant under which service engineers are stationed on-site for support and preventive maintenance of all material handling equipment, including management of the on-site spare-parts inventory. This arrangement enables the systems to be updated as new sorter technologies and software controls are introduced.
