Claim Text:
1. A device for transferring blister packs from a stamping station to a conveying means, the device comprising first and second suction arms for picking up the blister packs from the stamping station in a pick position, for moving the blister packs in a conveying direction, and for placing the blister packs on the conveying means in a place position, wherein one of the first and second suction arms is arranged on one side of a center plane of the device, and the other one arm of the first and second suction arms is arranged on the other side of the center plane; wherein the first and second suction arms are pivotable around a first axis, which is perpendicular to the conveying direction and perpendicular to the center plane, and wherein pivoting movements of the first and second suction arms are controlled in such a way that the two suction arms execute opposing back-and-forth pivoting movements; wherein each suction arm comprises a first segment, a second or middle segment, and a third segment; wherein the first segment of each suction arm is mounted pivotably around the first axis and comprises a section away from the first axis to which the second or middle segment is attached pivotably around a non-stationary second axis substantially perpendicular to the first axis, wherein the second segment, in turn, comprises a section a certain distance away from the second axis, to which a third segment is attached rotatably around a non-stationary third axis, which is substantially parallel to and away from the second axis; and wherein the third segment comprises a section on which at least one suction element for picking up and holding a blister pack is arranged; wherein a transfer movement of the blister packs from the pick position to the place position and back is a combination movement, which is composed at least of the pivoting movement around the first axis, the pivoting movement around the second axis, and the rotational movement around the third axis; wherein the blister packs are picked up from above by the at least one suction element in the pick position and placed onto the conveying means also from above in the place position; wherein the second segments are pivoted inward toward the center plane both when in the pick position and in the place position; and wherein, during the pivoting movements of the suction arms in opposite directions between the pick position and the place position, the second segments pivot away from each other so that the suction arms can pass by each other without colliding.
