  • a generic device is known for example from DE 42 35 516 C2, in which a transfer device takes a label from a label feed device and transfers it to a suction belt conveyor.
  • This suction tape conveyor leads the label past a gluing station before it connects the glued label to an object to be labeled.
  • the transfer device is designed as a rotor, on the circumferential surface of two opposite locations can be held with the help of negative pressure labels.
  • the suction belt conveyor is designed as a flexible endless belt, which is guided around corresponding pulleys. The labels are held in a known manner by means of negative pressure on the suction belt conveyor. For gluing, the suction tape conveyor guides the label past a gluing roller before it is brought into contact with an object to be labeled.
  • the known device is disadvantageous in particular when it comes to high labeling performance, because above all the principle of transferring labels onto the surface of the rotor (transfer device) and transferring them to the suction belt conveyor limits the possible performance.
  • the device according to the invention has a transfer device which comprises a rotor on which controllable pallets, each with a curved surface, are rotatably mounted, the controllable pallets being the Hold labels on the respective curved surface with the help of negative pressure and transport them between the label feed device and the suction belt conveyor.
  • Label feeder is possible.
  • the pallets can be operated in such a way that the respective curved transfer surface performs a full-surface rolling movement on the labels to be transferred.
  • the pallets can also be controlled in such a way that the labels are transferred to the suction belt conveyor in a rolling motion, the labels being able to be applied in very close succession.
  • the radius of curvature of the curved surface of the pallets is smaller than the sum of the respective distance of the axis of rotation of a pallet from the rotor axis and the minimum distance of the axis of rotation of the same pallet from the curved pallet surface. This for a given label length, allow a tight arrangement of the pallets, ie a small pitch on the rotor, without the pallets interfering with each other in their movement.
  • the radius of curvature of the curved surfaces of the individual pallets is particularly advantageously greater than the minimum distance of the curved surface from the respective axis of rotation about which the pallet rotates with reference to the transfer rotor. In this way, a larger effective pallet length is available for the transfer of longer labels without the rotor radius having to be increased.
  • guide elements that are connected to the pallets and a fixed link guide are provided that are designed in such a way that they interact with the guide elements in such a way that the pallets rotate about their axis of rotation relative to the rotor, at least during the label pick-up process and the transfer process , ie rotate.
  • a guide with corresponding guide elements makes it easy to control the pallets in such a way that e.g. a rolling movement of the curved surfaces takes place on the suction belt conveyor and also on the label to be taken over from the label feed device.
  • guide elements which are connected to the pallets and a fixed link guide are provided in such a way that their interaction causes the pallets to pivot, at least during the transfer process and the label pick-up process carry out.

  • the device can be used particularly advantageously for labeling cigarette boxes.
  • the cigarette boxes can be fed vertically from the transport device. Due to the shape of the standing cigarette boxes, a small pitch can be maintained, which leads to a further increase in the performance of the device.

  • the controllable pallets are located on a continuously driven transfer rotor 5.
  • the pallets sit on shafts which are driven to rotate or pivot about axes 3a.
  • the pallets in the area of the label chutes execute a brief rotary movement counterclockwise (arrow 3b), in the area of the suction conveyor 4 also counterclockwise (arrow 3c), while the rotor rotates clockwise (arrow 5b).

  • the pallet 3 is moved past the label chute lk by rotating the rotor 5.
  • the label is held by negative pressure, which is generated on the curved surface 3e of the pallets 3 by means of a plurality of radially extending vacuum bores.

  • the individual pallets 3 thus perform a swiveling movement on the path about the axis 5a both in the area of the label holder from the label feed device 1 and in the area of the transfer of the labels to the suction belt conveyor 4.
