Huge deployment for e-commerce giant
09 April 2015
TGW has installed an automated warehousing solution with 7.5km of conveyor equipment over five floors to ensure the shipping of up to 7,500 packages per hour for Chinese 3PL and e-commerce specialist CNSS.
The installation in Danyang, 200 kilometres from Shanghai.
Albert Fischlmayr, TGW project manager explains: "There is no one permanent customer storing its goods in the warehouse; it might be a different customer every few weeks. This is why the installation was designed to offer highest performance during peak times.”
Consequently, TGW’s solution allows for all available processes to work independent of each other, which ensures shortest throughput times through the entire installation and increases the efficiency of CNSS’ processes.
It starts with the arrival of goods, which are immediately forwarded to TGW’s conveyors via radio controls. "We connected all the levels in the building using our conveyor equipment to transport the goods along 7.5 kilometres of conveyors, three channelisers and two TGW Natrix sorters,” Fischlmayr says. "CNSS is using its own radio controls, so we provided the individual interface to make it work.”
As soon as an order has been transmitted online, the goods are manually placed on the conveyor lines and transported downwards to the ground floor. Scanners control the transported goods and prove the identity and the content of the totes.
"The totes arrive on the ground floor and are conveyed to a pick-to-wall picking system. This has shelves that are accessible from both sides. One picking employee puts the goods into a designated shelf by using a put-to-light system. On the other side of the shelf, a light shows the packing employee when an order is ready to be packed,” explains the project manager. The goods are packed into cartons and immediately sent onward on their journey towards the sorter.
The longest TGW Natrix sorter has a length of 100 metres with 30 chutes. It ensures that every package is sent to the correct shipping line. The other one, with four chutes, distributes the picked totes to the correct pick-to-wall lines. Using this system CNSS is able to send up to 7,500 packages per hour depending on the size of the cartons.
Due to the large number of conveyors, an intelligent energy management solution was needed. TGW addressed this with an automated stand-by mode that is initiated during off-peak times so the installation operates sustainably and efficiently.
Jay Wang, CEO at CNSS said: "By combining excellent equipment, professional experts and tailor-made software, we have super capacity of processing an average of 1.5 million cargos in pieces daily. At peak seasons, we will be able to handle 2 million cargos daily.”
