Abstract

A method of storing and picking individual articles and/or packaging units in a storage system includes separating and transferring individual articles from incoming-load carriers and depalletizing and separating packaging units from incoming-load carriers. Individual articles, load carriers and packaging units are transported to a warehouse for intermediate storage of individual articles on or in load carriers and packaging units. Individual articles and packing units are picked at a picking area and the picked articles or packing units loaded onto order-load carriers. Individual articles, load carriers and packaging units are transported from the warehouse to the picking area. Load carriers are used only for the transportation and storage of non-conveyable individual articles or non-conveyable packing units and conveyable packaging units and wherein conveyable individual articles are transported and stored directly and without load carriers.

Claims

1. A method of storing and picking at least one chosen from individual articles and packaging units in a storage system, said method comprising:

depalletizing, separating and transferring individual articles from incoming-load carriers and positioning non-conveyable ones of the individual articles in load carriers;

depalletizing and separating packaging units from incoming-load carriers and positioning non-conveyable ones of said packaging units in load carriers;

transporting conveyable individual articles, load carriers and conveyable packaging units to a warehouse and storing conveyable individual articles, load carriers and conveyable packaging units in the warehouse;

picking at least one chosen from individual articles and packaging units at a picking area and loading the picked articles or packaging units onto order-load carriers; and

transporting conveyable individual articles, load carriers and conveyable packaging units from the warehouse to the picking area, wherein load carriers are used only for the transportation and storage of non-conveyable individual articles and non-conveyable packing units and wherein conveyable individual articles and conveyable packaging units are transported and stored directly and without load carriers, wherein the warehouse includes storage spaces for the conveyable individual articles and conveyable individual article or conveyable packaging unit depends upon the width of the conveyable individual article or conveyable packaging unit.

2. The method as claimed in claim 1, wherein conveyable individual articles or conveyable packaging units comprise a surface area greater than or equal to 10 cm×

10 cm.

3. The method as claimed in claim 2, wherein the picking includes automatic or manual picking.

4. The method as claimed in claim 3, wherein the load carriers are containers.

5. The method as claimed in claim 4 including emptying the containers, wherein the containers comprise a floor that can be lifted out or a pivotable sidewall.

6. The method as claimed in claim 3 including removing from storage and transporting to the picking area in a sorted and sequenced manner the conveyable individual articles, load carriers and conveyable packaging units.

7. The method as claimed in claim 2, wherein the load carriers are containers.

8. The method as claimed in claim 7 including emptying the containers, wherein the containers comprise a floor that can be lifted out or a pivotable sidewall.

9. The method as claimed in claim 2 including removing from storage and transporting to the picking area in a sorted and sequenced manner the conveyable individual articles, load carriers and conveyable packaging units.

10. The method as claimed in claim 1, wherein the picking includes automatic or manual picking.

11. The method as claimed in claim 10, wherein the load carriers are containers.

12. The method as claimed in claim 11 including emptying the containers, wherein the containers comprise a floor that can be lifted out or a pivotable sidewall.

13. The method as claimed in claim 10 including removing from storage and transporting to the picking area in a sorted and sequenced manner the conveyable individual articles, load carriers and conveyable packaging units.

14. The method as claimed in claim 1, wherein the load carriers are containers.

15. The method as claimed in claim 14 including emptying the containers, wherein the containers comprise a floor that can be lifted out or a pivotable sidewall.

16. The method as claimed in claim 14 including removing from storage and transporting to the picking area in a sorted and sequenced manner the conveyable individual articles, load carriers and conveyable packaging units.

17. The method as claimed in claim 1 including removing from storage and transporting to the picking area in a sorted and sequenced manner the conveyable individual articles, load carriers and conveyable packaging units.

18. The method as claimed in claim 1, wherein said transporting is performed by a shuttle that comprises a transport surface, a pair of telescopic arms disposed on opposite sides of the transport surface, wherein said telescopic arms can be extended transversely with respect to the direction of travel of the shuttle and wherein each of said telescopic arms comprises at least three pivotable fingers which can be moved between a working position, which protrudes from the telescopic arm and a rest position retracted into the telescopic arm, wherein spacing between the telescopic arms is mutually adjustable.

19. The method as claimed in claim 1, wherein said separating and transferring is performed with a depalletizer.

20. The method as claimed in claim 1, wherein said separating and transferring includes depositing the non-conveyable individual articles on or in load carriers.

21. The method as claimed in claim 1, wherein said depalletizing and separating includes depositing the non-conveyable packaging units on or in load carriers.

22. The method as claimed in claim 1 wherein said warehouse comprises multiple stacked racks and wherein the storage spaces for the load carriers'"'"' conveyable individual articles and conveyable packaging units are at a same stacked rack in said warehouse.
