Abstract:
1. A device for transferring folding boxes comprising: a planetary carrier, which is driven in a predetermined rotational direction at a predetermined rotational speed around a first stationary axis, and which comprises, as its planets, a first suction arm and a second suction arm, each of which comprising at least one suction element, wherein the first suction arm is supported in the planetary carrier with freedom to rotate around a non-stationary second horizontal axis, and wherein the second suction arm is supported in the planetary carrier with freedom to rotate around a non-stationary third horizontal axis; two roller star units, wherein the first roller star unit is arranged in an area of the second horizontal axis and is connected to the first suction arm, and wherein the second roller star unit is arranged in an area of the third horizontal axis and is connected to the second suction arm; and a cam disk unit comprising first and second cam disks having different curved guide surfaces arranged on an outside periphery of the cam disks, wherein both the first roller star unit and the second roller star unit are arranged to be guided along the curved guide surfaces of the two cam disks in such a way that, upon rotation of the planetary carrier around the first horizontal axis, the first suction arm follows a repeating, predetermined, irregular rotational rhythm around the non-stationary second horizontal axis, and, after a certain time delay, the second suction arm follows the same predetermined rotational rhythm around the non-stationary third horizontal axis; wherein a drive for the cam disk unit is provided, which is designed to turn the cam disk unit around the first horizontal axis in the rotational direction of the planetary carrier but at a rotational speed which is double the rotational speed of the planetary carrier.
