Abstract
The invention relates to an order picking device ( 1 ), in particular a storage lift, with at least one retrieval and/or storage point ( 14 ) for stored goods ( 10 ) and/or stored goods carriers ( 8 ), a method for calculating a height distribution ( 38 ) of stored goods ( 10 ) on a stored goods carrier ( 8 ), a computer program product, and a computer-readable memory medium. The order picking device ( 1 ) has stored goods carriers ( 8 ) that are stored one above the other in storage places ( 4 ) and on which stored goods ( 10 ) are deposited. The aim of the invention is to make optimal use of the storage space provided by the order picking device ( 1 ). For this purpose, the order picking device ( 1 ) has at least one detector device ( 24 ) for determining a height distribution ( 38 ) of the stored goods ( 10 ) or of the stored goods carrier ( 8 ) and for providing data ( 28 ) that represent the height distribution ( 38 ). The detector device ( 24 ) includes a plurality of reflection light sensors ( 25 ) arranged in parallel to one another. The method comprises determining a location-dependent height ( 26 ) of stored goods ( 10 ) using a plurality of reflection light sensors ( 25 ) arranged in parallel to one another.
