<p>This invention relates to a labeling device (200) for labeling objects (211), in particular moving objects, where a linearly displaceable piston (201) is operable connected to a moving mechanism (209) for moving the piston from a resting position to a labeling position and vice versa. A labeling pad (202) is arranged at the distal end of the piston for carrying an adhesive label and for affixing the adhesive label to an object via physical contact with the object at said labeling position of the piston. A force-switching-state system (210) is provided operable to maintain the piston in relation to the moving mechanism in an attracting force state such that the piston moves with the moving mechanism from the resting position to the labeling position. The physical contact with the object creates an opposite repelling force from the object onto the labeling carrying mechanism causing a separation between the displaceable piston from the moving mechanism. This separation causes a change of the force state of the displaceable piston from being in an attracting force state to a repelling force stage causing the linearly displaceable piston to move back to the resting position.</p> |
