  • Patent number: 4976344
    Abstract: A method for transferring articles from a conveyor to a rack or magazine. The articles are gripped one at a time by a gripping device and are moved from the conveyor while being brought to a correct position of alignment in relation to the rack, whereafter the article is placed in the rack. In accordance with the invention the article transfer is effected in at least two transfer stations which work in parallel and which are arranged one after the other along the conveyor path, each transfer station including an industrial robot. A plurality of racks are moved sequentially along a path which extends through all transfer stations. Only a given part of each rack is filled in each transfer station, such that the rack will be completely filled subsequent to passing through all the transfer stations.
