Definitions

  • the invention relates to a device for attaching handles to packaging or groups of packaging. Furthermore, the present invention relates to a method for attaching handles to packaging or groups of packaging.
  • Bottled drinks Individually packaged goods, such as Bottled drinks, grouped into larger packaging groups or containers. These are then e.g. put together into so-called tray packs.
  • tray packs e.g. six bottles joined together by means of a cardboard base and a shrink film to form a mechanically stable sales unit.
  • bottles or other containers together it is also known to join bottles or other containers together to form a packaging unit in that the containers are glued to one another using at least one adhesive.
  • bottles e.g. Bottles, cans, containers etc. are called containers for the sake of simplicity.
  • the carrying handle is a carrying tape which is self-adhesive on one side and is generally a plastic tape. While the beginning and end of this carrier tape are pressed onto one side of the container by suitable devices and thus also glued to it, the adhesive side of the middle piece of this carrier tape is usually covered with a paper strip in order to ensure that a customer's fingers stick to the carrier tape to avoid and to ensure the formation of the handle in the form of a strap. Essentially two methods are used in industry for the production of such carrier tapes.
  • these tapes are equipped with the paper strip described above during their actual manufacturing process, so that these strips only have to be cut to length and attached from an endless strip-shaped carrier tape material within the machine which attaches the carrying handles.
  • a disadvantage of this method is that any change in the shape of the handle, be it the total length, the length of the adhesive points or the length of the strap, results in a change in the plastic strip.
  • Another method uses a strip-shaped carrier tape material that is completely self-adhesive on one side. Inside the machine that attaches the handles, the section of this tape that lies between the two desired adhesive points is now provided with a paper strip, the required adhesive spots remaining free at the beginning and at the end of the tape. With this procedure, since the length of the carrier tape, the position and the length of the paper strip can be easily adapted to changing requirements, frequent changing of the carrier tape material can be dispensed with, which is a great advantage in practice.
  • carrier tape material or carrier tape apply analogously to the use of carrier tape materials that are made of other materials, such as e.g. Paper or metal, or any combination of these materials.
  • a device in which the handle is attached by a comparatively complicated arrangement of different levers and pressure rollers. It is disadvantageous that this device is essentially only suitable for packet-shaped containers, and that the carrying handle can only be adapted to a limited extent to changing container dimensions.
  • a device which has a drivable rotating plate arranged centrally around a transverse to the transport direction of the container. The radially outer ends of the turntable are each rounded and provided with two L-shaped levers as holding means for fixing the endless carrier tape material provided on one side with an adhesive layer covered in sections, and with a radially extendable cutting edge as a cutting device for separating the handle from the carrier tape material.
  • the rotating plate stands vertically and protrudes with a first end into the transport path of the containers, with a section of the carrier tape material corresponding to the length of the later carrying handle being held on the side facing the containers with an adhesive layer pointing outwards between the two ends of the rotating plate becomes.
  • An incoming container hits the rotating plate with its front, which is defined in relation to the transport direction, whereby the beginning of the handle is attached to the container.
  • the rotary plate then rotates through 180 degrees, the container simultaneously moving a certain amount, so that the rotary movement is terminated in that the second end of the rotary plate touches the back of the container. With this touch, the other end of the handle is attached to the back of the container.
  • the cutting device arranged in the rotating plate separates the handle from the endless carrier tape material.
  • a disadvantage of such a device is that the implementation of the non-uniform rotational movement of the rotary plate causes a high level of control expenditure, and large drive powers must also be provided due to the high angular accelerations required.
  • the length of the handle is determined by the geometric shape of the device, so that adaptation to changed container dimensions can only be achieved by replacing the rotating plate and extensive adjustment work.
  • the carrying handle applicator essentially consists of a three-armed rotor, the horizontal axis of rotation of which is arranged transversely to the conveying direction of the containers.
  • Each of these rotor arms is equipped with a belt guide for the carrier tape material, a holding and / or pressing device and a cutting tool.
  • a vacuum probe which is supposed to attract the carrier tape material without contact, so that the carrier tape material does not connect the ends of the rotor arms directly in a straight line, but essentially follows the inner contour of the rotor.
  • the holding and / or pressing device arranged on the rotor arm often also generates a holding force between the holding and / or pressing device and the continuous belt material even after or during the application and gluing of the carrier tape material to the packaging material or the group of packaging materials becomes.
  • the respective rotor arm is turned away after pressing and applying the carrier tape material to the packaging material or the group of packaging materials and / or the packaging material or the packaging material group moving away from the rotor arm, this in turn can lead to an unwanted detachment of the belt material from the packaging material or the packaging material group.
  • the invention relates to a device for attaching carrying handles to packaging or groups of packaging, by means of which the packaging or groups of packaging transported on a transport device in a transport direction can each be provided with at least one self-adhesive carrying handle.

  • a pressure distribution arrangement is provided which is designed to apply at least temporarily a first negative pressure level to the respective suction area of an associated holding and / or pressing device of the corresponding applicator arm, depending on the rotational position.
  • the carrying handle can be detached from the applicator arms particularly advantageously without the carrying handle still being held on the holding and / or pressing device after application.
  • Pressure distribution arrangement is designed to act on the respective suction area of an associated holding and / or pressing device of the corresponding applicator arm, at least temporarily, with at least a first vacuum level, depending on the relative rotational position of the carrying handle applicator unit.
