Definitions
- the invention relates to a device for attaching handles to packaging or groups of packaging.
- the present invention also relates to a method for attaching handles to packaging or groups of packaging.
- Individually packaged goods such as bottled beverages
- tray packs For example, six bottles are joined together using a cardboard base and shrink film to form a mechanically stable sales unit.
- packaging means or packaging known in the art such as bottles, cans, containers, etc., are referred to as containers for the sake of simplicity.
- the handle is a carrier tape which is self-adhesive on one side and is usually a plastic tape. During the beginning and end of this tape through suitable devices on each side of the
- a strip-shaped carrier tape material is used, which is completely self-adhesive on one side. Inside the machine, which attaches the handles, the section of this carrier tape located between the two desired adhesive locations is provided with a paper strip, the required adhesive locations at the beginning and at the end of the carrier tape remaining free.
- carrier tape material or carrier tape also apply analogously to the use of carrier tape materials that are made of other materials, such as paper or metal, or of any combination of these materials.
- a device which has a drivable rotating plate arranged in the center around a rotating plate arranged transversely 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, which is 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 is vertical and protrudes with a first end into the transport path of the container, with a section of the carrier tape material corresponding to the length of the later carrying handle with an outwardly directed adhesive layer being held between the two ends of the rotating plate on the side facing the containers becomes.
- An incoming container hits the rotating plate with its front side, 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 moving further by a certain amount at the same time, so that the rotary movement ends in the fact that the second end of the rotary plate touches the rear of the container. With this contact, the other end of the handle is attached to the back of the container.
- the cutting device arranged in the turntable 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 turntable results in a high level of control engineering effort, with high drive powers also having to 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 a Adaptation to changed container dimensions can only be done by exchanging the turntable and extensive adjustment work.
- the handle applicator consists essentially of a three-armed rotor, the horizontal axis of rotation of which is arranged transversely to the conveying direction of the container.
- Each of these rotor arms is equipped with a tape guide for the carrier tape material, a holding and / or pressing device and a cutting tool.
- a vacuum probe Between the rotor arms, near the hub of the rotor, there is a vacuum probe, which is intended 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 actual attachment of the handle takes place in that the containers run against a first rotor arm and thereby take over the beginning of the handle.
- the containers then pass under the rotating rotor and are provided with the other end of the handle by the respective following rotor arm, the cutting tool located at the end of the respective rotor arm severing the support tape material in the correct division.
- All components of the handle applicator unit are set to a specific format, in particular the length of a handle and the attachment height of this handle, and are coordinated with one another.
- a format adaptation to a different handle length and / or attachment height is associated with a conversion of the handle applicator unit and is therefore time-consuming and expensive.
- the prior art depends on the construction of the handle applicator unit, which is not adjustable in length.
- the transported length of the handle results from the length and width of the applicator arm of the handle applicator unit.
- a cylinder can be extended to apply longer handles.
- the set lifting rod on the handle applicator unit can only be adjusted once, and from then on must remain in this position for all other formats. Any stretch, i.e. elongation, in the handle due to errors or control inaccuracies can lead to changes in the handle lengths during operation that cannot currently be compensated.
- system body acting as a hammer moves into the handle at the moment depending on an eccentric and the curve setting of the driven handle applicator unit in order to then place it in the carrier unit in the correct shape. Due to dynamics, this can lead to knocking into the handle.
- the object of the present invention is therefore to provide a device and method for attaching handles to packaging or groups of packaging, which is further improved compared to the prior art, which does not have the disadvantages of the prior art and in particular a simple format adaptation to different lengths and heights of a handle enables.
