<p>The invention relates to a method for moving products (2), i.e. picking up, transferring and placement thereof, in particular packaging units such as egg boxes as well as patterns thereof, wherein the packaging units comprise in particular a rectangular form with, at least partly, an edge part (23) therearound, wherein moving is carried out with a gripper (1) with at least two gripper blades 13), substantially parallel to each other and rotational about corresponding parallel axes (11A,12A), for gripping a product at two opposite sides at the edge parts (23) mentioned, and with slightly inwardly bent gripper blade edges (14) which grip close - fittingly around the edge parts (23) mentioned, while after placement of the packaging units on a substantially horizontal supporting surface the gripper blades (13) are rotated about the axes mentioned, while the gripper blades move substantially against the top of the packaging units and simultaneously, the gripper blade edges move away from and upwards relative to the edge part (23) while thereupon, the gripper blade edges (14) take up a substantially vertical position with their ends against the edge part (23), whereupon the gripper (1) is moved in substantially vertical direction away from the packaging unit and releases this. With this manner of release, in a highly suitable manner, with grippers, patterns can be formed of packaging units to be placed next to each other, such as egg boxes.</p> |
