Definitions

  • the invention relates to an order picking system and a method for order picking a picking order using such an order picking system.
  • the order picking system comprises an overhead conveyor device with a plurality of transport carriers for transporting hanging goods and a support structure on which a plurality of travel routes are arranged. The travel routes form a transport path along which the transport carriers can be moved.
  • the order picking system comprises a loading area with at least one loading station for loading the transport carriers with hanging goods, a storage area for storing the hanging goods on the transport carriers and an order picking area with at least one picking station for unloading the transport carriers and for picking order goods.
  • the order picking area can therefore comprise one or more picking stations for unloading the transport carriers and for picking order goods.
  • the overhead conveyor device of the order picking system comprises a storage device for transferring the transport carriers from the loading area via a collection travel area into the storage area, a storage block arranged in the storage area and a retrieval device for transferring the transport carriers from the storage area via a distribution travel area into the order picking area.
  • the storage block has at least one storage level with one storage row, wherein the storage row comprises several storage locations.
  • picking orders that include ordered goods can be fulfilled as quickly and efficiently as possible.
  • the ordered goods must be transported from the respective storage location to the picking station within a short time and made available at the picking station.
  • items that are frequently ordered are stored close to a warehouse exit and items that are rarely ordered are stored further away from the warehouse exit. This optimizes transport times and picking orders can be fulfilled quickly and efficiently.
  • the disadvantage here is that a storage location cannot be used in a space-optimized manner, which is why the warehouse usually has to be oversized.
  • the hanging goods on transport carriers are usually temporarily stored in large buffer carousels after the transport carriers have been loaded until they are needed for a picking order.
  • the transport carriers are moved in a circle via deflection tracks, which means that the buffer carousels require a lot of space and are very technically complex.
  • the buffer carousels are designed to accommodate many hundreds to thousands of transport carriers, which means that access to a single transport carrier is particularly long.
  • An exemplary order picking system is known from DE 102018 221 043 A1, in which a storage block is provided with a circulating carousel that can be filled with hanging goods from a loading station by inserting the transport carriers into it. Between the storage block and the order picking station there is an order buffer with storage lanes that work according to the first-in-first-out principle.
  • the order or hanging goods can be transported from the storage block to the order buffer and temporarily stored there.
  • the order goods can be sorted in a sorting device downstream of the order buffer so that the order goods can be provided in a pure order and/or items of the order goods can be provided in a desired order at the order picking station.
  • One object of the invention is to create an improved order picking system and an improved order picking method.
  • the aforementioned disadvantages are to be overcome and an efficient fulfillment of order picking orders is to be made possible.
  • the at least one storage level comprises a storage driving area into which the transport carriers can be transferred from the storage device, and a retrieval driving area from which the transport carriers can be transferred to the retrieval device.

  • One advantage achieved with the invention is that a large number of storage locations are available, which means that access time to individual transport carriers is particularly short. This means that the ordered goods, in particular articles of the ordered goods, can be quickly removed from the storage area and made available at at least one picking station.
  • the arrangement of the storage locations along the storage travel area means that the transport carriers can reach any storage location. This creates a particularly uniform storage density and optimizes the use of a storage location.
  • the transport carriers are movable, in particular movable, in the travel areas, in particular in the collection travel area, in the storage travel area, in the storage travel area, in the retrieval travel area and in the distribution travel area.
