Distribution center for office supplies

Dispatch of 11,000 parcels with office supplies per day

Soennecken eG is the purchasing and marketing organization with the biggest turnover for office supplies in Europe. From Overath, about 570 specialist suppliers at over 1200 locations are serviced. The distribution previously handled by a third party logistics provider has been brought back to the headquarters of the company and is carried out by Soennecken LogServe.

Unitechnik has realized the complete logistics system as a general contractor. An automatic storage and retrieval system provides the goods for the picking platform. Very narrow aisle trucks with radio data terminals supply the storage bins in the 42 picking zones. Picking is done directly in the order carton by Pick-by-Voice.

The tray conveyors handle the transportation of the order cartons - from the automatic carton opener via the picking zones and the packing area to the automatic carton closer and the dispatch area. Up to 11,000 parcels and 600 pallets are leaving the Overath logistics center every day.
