Apparatus and method for handling articles
The method of the present invention removes at least a plurality of articles ( 02 ) arriving consecutively in a transport direction (FR) from an infeed ( 03 ), and subsequently, arranging and grouping the articles ( 02 ), while simultaneously lifting and collectively transferring the article ( 02 ) from the infeed ( 03 ) to a staging surface ( 04 ). At the staging area are one or more outer packagings ( 05 ), and into which the articles ( 02 ) are placed. Individually or groupwise, as seen in a direction in parallel to the transport direction (FR), the individual distances between the articles ( 02 ) corresponding to a defined arrangement ( 20 ) are increased and/or decreased, and finally, the articles ( 02 ) are simultaneously lowered and released into the one or a plurality of outer packagings ( 05 ). The apparatus of the present invention comprises an infeed ( 03 ) of articles ( 02 ) being transported, at least one staging surface ( 04 ) arranged next to the infeed ( 03 ). On the staging surface ( 04 ), outer packagings ( 05 ) are staged, and which will be filled with articles ( 02 ) removed from the infeed ( 03 ). From the staging surface ( 04 ), the filled outer packagings ( 05 ) are discharged. A gripping device ( 07 ) is used to simultaneously seize a plurality of articles ( 02 ) from the infeed ( 03 ). The gripping device ( 07 ) has one gripper head ( 70 ) per article. The gripping device ( 07 ) has at least one manipulator ( 71 ) with a horizontally and vertically movable manipulator head ( 72 ).
