1. A device for transferring blister packs comprisinga first transfer unit for transferring the blister packs from a stamping station, a transport means, or an intermediate storage area to an intermediate place element;

  • anda second transfer unit for transferring the blister packs from the intermediate place element to a conveying means or a storage area,wherein the second transfer unit comprises a first suction arm, which is movable between a first picking position, in which the first suction arm picks a first blister pack from a first intermediate place position on the intermediate place element, and a first placing position, in which the first suction arm places the first blister pack in a final place position on the conveying means or in the storage area;

    wherein the second transfer unit comprises a second suction arm, which is movable between a second picking position, in which the second suction arm picks a second blister pack from a second intermediate place position on the intermediate place element, and a second placing position, in which the second suction arm places the second blister pack in the same final place position;

    wherein the first and second suction arms are arranged on either side of a longitudinal center plane of the device;

    wherein each of the first and second suction arms comprises a first segment and a second segment, wherein the first segment of each of the first and second suction arms is mounted rotatably around an associated first axis, which is perpendicular to the longitudinal center plane;

    wherein the first segment of each of the first and second suction arms comprises a section to which the second segment is attached rotatably around a non-stationary second axis, which is substantially perpendicular to the first axis, wherein a suction device for picking and holding a blister pack is arranged on the second segment;

    wherein the first and second suction arms are configured and actuated such that a movement of one of the first and second suction arms from the first or second picking position to the first or second placing position and back is a combined movement, which comprises at least a first rotational movement of the first segment and of the second segment around the first axis and a second rotational movement of the second segment around the second axis;

    wherein the first and second suction arms are configured and actuated such that the blister packs in the first and second intermediate place positions are picked from above by the suction devices of the first and second suction arms and are also placed from above in the final place position;

    wherein the first and second intermediate place positions are outwardly offset from the longitudinal center plane, and the final place position is arranged in an area of the longitudinal center plane;

    wherein the second axis of the first suction arm is arranged such that, during the first rotational movement of the first segment of the first suction arm, the second axis of the first suction arm moves in a first plane, which intersects the intermediate place position or a lateral projection thereof along a first straight line, which is laterally offset from a center of the first intermediate place position; and

    wherein the second axis of the second suction arm is arranged such that, during the first rotational movement of the first segment of the second suction arm, the second axis of the second suction arm moves in a second plane, which intersects the second intermediate place position or a lateral projection thereof along a second straight line, which is laterally offset from a center of the second intermediate place position.
