Definitions

  • the invention relates to a device for applying Labels according to the preamble of claim 1.
  • the present invention is specifically for the application of Tax labels on cigarette boxes can however for other applications where labels are on Packaging must be applied.
  • a generic device is e.g. from DE 42 35 516 C2 known, in which a transfer device from a Label feeder takes over one label each passes to a suction belt conveyor.
  • This suction belt conveyor passes the label past a gluing station before he glued the label with one to be labeled Relates object.
  • the transfer device is designed as a rotor, on its circumferential surface on two opposite locations with the help of vacuum labels can be captured.
  • the suction belt conveyor is as flexible endless belt formed around corresponding Pulleys is led around.
  • the labels come with Help of negative pressure on the suction belt conveyor in known Kept wise.
  • the suction belt conveyor leads to gluing Label past a glue roll before it is with a object to be labeled is brought into contact.
  • the known device is particularly when it comes to high labeling performance goes, disadvantageous because above all the principle of applying labels to the surface of the rotor (transfer device) and the transfer to the Suction belt conveyor limits the possible performance.
  • EP 0499 818 A1 describes a labeling device for attaching labels to vessels known that the labels by rolling an adhesive surface coated with cold glue from from a label storage container.
  • the device has a plurality of such a curved surface with adhesive surfaces that are even Pitch distance controlled on a common pitch circle of a rotor relative to this are pivotally mounted.
  • the glued label is attached with a mechanical gripper fingers equipped gripper cylinder peeled off the adhesive surface and pressed onto a container with the glued back.
  • This requires Labeling device an outward gripper cylinder and does not allow an exclusive Glueing of the labels with hot glue, as this would otherwise be removed from the adhesive surface would tear due to the high adhesive strength of the hot melt.
  • a labeling device working with rotating vacuum segments is from DE 29 07 112 A1 known. Required to remove a label from a label storage container this device has two rotating vacuum segments, the first segment being a label removed from a storage container and transferred to the second segment. This segment transfers the label to a rotating labeling cylinder, which puts it on a transmits the object to be equipped. The relative movement of the two rotating Vacuum segments must match each other for a smooth labeling process be coordinated. Unfortunately, the labels are only removed during the removal process Area of a label edge detected and held. As a result, the withdrawal rate is strong limited.
  • 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 Labels with the help of negative pressure on the respective keep curved surface and between the Label feeder and the suction belt conveyor transport.
  • the pallets can be controlled so that a precise transfer of the labels from the Label feeder is possible. For example, can they Pallets are operated so that the respective curved Takeover area on the labels to be taken over full-surface rolling movement. Likewise, the Pallets can be controlled so that the labels on the Suction belt conveyors are passed in a rolling motion, the labels being applied in very close succession can.
  • the radius of curvature of the curved surface of the pallets is smaller than the sum 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 is. This leaves a tight arrangement of the given label length Pallets, i.e. a small pitch on the rotor without the pallets mutually in their Disrupt movement.
  • the radius of curvature is particularly advantageous curved surfaces of the individual pallets larger than that minimum distance of the curved surface from the respective Axis of rotation around which the pallet is related Transfer rotor turns. In this way there is a bigger one effective pallet length for transferring longer labels available without increasing the rotor radius got to.
  • guide elements are connected to the pallets, and a fixed one Link guide provided, which is designed such that it interacts with the guide elements in such a way that the pallets at least during the label pick-up process and during the transfer process about its axis of rotation relative to the rotor turn, i.e. rotate.
  • a backdrop with corresponding guide elements open it easy way to control the pallets so that e.g. a rolling motion of the curved surfaces on the Suction belt conveyor takes place and on the too accepting label from the label feeder.
  • guide elements are connected to the pallets, and a fixed one Backdrop guidance provided such that their interaction leads to the pallets at least during the transfer process and a pivoting movement during the label pick-up process carry out.
  • Embodiments are the movements of the pallets their axis of rotation during the transfer process and / or during Label picking process and the rotation of the rotor are not in the same direction.
  • Adhesive spray device as Adhesive application device provided. This makes possible a very even and economical application of adhesive, which, in contrast to a glue roll, is much less Takes up space.
  • the labeling device can be particularly advantageous of cigarette boxes. Particularly the boxes can be removed from the transport device be fed vertically. It can because of Shape of the standing cigarette boxes a little Pitch will be observed, leading to further Increased performance of the device leads.
  • Figure 1 shows the essential in a perspective view Components of a device according to the invention.
  • Reference numeral 1 is a label feeder with individual label slots or magazines 1a to 1k shown that are so slidably mounted that they successively brought to the place of that shaft 1k can be the one in the figure with the controllable pallets 3 is currently working together.
  • the controllable pallets are located on a continuously driven transfer rotor 5.
  • the pallets sit on shafts that rotate or rotate about axes 3a are pivotally driven.
  • the pallets in the area Label slots a short rotation against the Clockwise from (arrow 3b), in the area of the suction conveyor 4 also counterclockwise (arrow 3c), during the The rotor rotates clockwise (arrow 5b).
  • Conveyor belt 10 conveys to be labeled Packaging container 11, e.g. cigarette, continuously in a vertical position.
  • the Labels are intended to be applied to the top surface 11a become. It can e.g. are tax strips.
  • this device works as follows.
  • Label supplier 1 the labels 2 are stacked kept. Side by side, complete exist manholes with labels 1a to 1k, so that at Emptying a label slot by manual or automatic feeding of the next label slot continuous operation is ensured.
  • the labels are individually at the end facing the rotor 5 in the removal position of the label slot 1k from one on the front label all over rolling pallet 3 taken over.
  • the pallet 3 is through Rotation of the rotor 5 on the label slot 1k moved past.
  • the label is under pressure held on the curved surface 3e of the pallets 3 by means of a plurality of radially extending Vacuum drilling is generated.
  • the suction belt conveyor moves in the direction 4a and leads the labels continue towards the transport device 10.
  • Adhesive spray device provided in the Drawing is not shown for reasons of clarity. With their help, glue is applied to the labels applied.
