Abstract

A device for attaching adhesive labels to packaged goods has a compressed air source and a vacuum source that are alternatingly connected by program-controlled two way valves to air inlet openings of a pneumatic cylinder. A main piston is connected to the upper end of a hollow piston rod and is guided between an upper and a lower dead center position in the pneumatic cylinder. The hollow piston rod has a lateral air opening within the cylinder. A suction holder is connected to a lower end of the hollow rod positioned external to the pneumatic cylinder. The suction holder has a suction channel axially connectable to the hollow piston rod and closeable partially by a check valve. A label transfer unit has a label transfer position in which a respective label is positioned at a small distance below the suction holder when in its upper position. A control device lowers the suction holder into the lower position for receiving the label. The control device has a control member that reciprocates vertically parallel to the pneumatic cylinder and cooperates with an abutment positioned external to the cylinder at the piston rod/suction holder. The main piston has a permanent magnet at its up…
