Abstract

Described and depicted is an application device for applying additional elements, in particular straws, to packages, preferably cardboard composite packages, having at least one transport device for transporting the packages along a transport track having at least one applicator adjustable, from a pick-up position for picking up the additional elements, to an application position for applying the additional elements to the packages and back. To facilitate the application of the additional elements at a higher application speed without having to take on considerable losses with regard to the reliability of the application of the additional elements or the complexity of the equipment, it is provided that at least one positioning belt extending at least in sections along the transport track of the packages is provided such that the additional elements applied to the packages are held on the packages, in particular pressed onto the packages along at least a part of the transport track by the positioning belt.

First claim

The invention claimed is:

1. An application device for applying additional elements to packages having at least one transport device for transporting the packages along a transport track, having at least one applicator adjustable, from a pick-up position for picking up the additional elements, to an application position for applying the additional elements to the packages and back,
wherein
at least one positioning belt extending at least in sections along the transport track of the packages is provided such that the additional elements applied to the packages are held on the packages along at least a part of the transport track by the positioning belt and the at least one positioning belt revolves around a deflection rotatable about an axis of rotation of the at least one applicator, and in that, the axis of rotation of the deflection and the axis of rotation of the at least one applicator are spaced apart from one another in that the distance between the axis of rotation of the deflection and the axis of rotation of the applicator wheel, is less than the width, of the packages transverse to the transport track of the packages.

2. The application device according to claim 1 ,
wherein
at least one transportation belt of the transport device is designed to be moved at least in sections along the transport track in at least substantially the same direction and/or at least substantially at the same speed as the packages and/or in that the at least one positioning belt is designed as a belt and/or as a chain.

3. The application device according to claim 1 ,
wherein
in the region where the additional elements are held on the packages and/or in the region where the at least one positioning belt approaches the transport track of the packages, a guide device guiding the positioning belt in the transport direction is provided, and in that, the guide device is in contact with the positioning belt on the side of the positioning belt facing away from the packages.

4. The application device according to claim 1 ,
wherein
the at least one applicator is provided pivotably about a pivoting axis of rotation, and in that, a plurality of applicators designed as an applicator wheel, is uniformly distributed around the axis of rotation.

5. The application device according to claim 1 ,
wherein
the axis of rotation of the deflection and the pivoting axis or axis of rotation of the applicator wheel are spaced apart in a direction at least substantially perpendicular to the transport track of the packages at the point of application of the additional elements on the packages.

6. The application device according to claim 1 ,
wherein
the at least one applicator comprises an applicator finger adjustable and pivotable, in the direction of an additional element guide and/or a package, for at least partially receiving the additional element, for applying the additional element and/or for holding the additional element, and in that, the application finger is spring-loaded and/or preloaded in the direction of the additional element guide and/or the package.

7. The application device according to claim 6 ,
wherein
the at least one applicator comprises, at least adjacent to the application finger, a guide finger for guiding the additional element at least partially held and received by the application finger in an interlocking manner in the transport direction of the additional element, and/or in that the application finger of the applicator and the additional element guide are designed such that the additional element is in contact with both the application finger as well as the additional element guide at least in sections before the application of additional elements to the packages.

8. The application device according to claim 6 ,
wherein
the additional element guide is at the rear end in the transport direction at least substantially in contact with a package at least substantially adjacent to the surface section to be provided with the additional element.

9. The application device according to claim 1 ,
wherein
the at least one transport device comprising a transportation belt comprising a recess is provided for transporting the packages along the transport track, and in that the transportation belt is provided on the side of the packages facing away from the at least one positioning belt.

10. The application device according to claim 1 ,
wherein
the additional elements applied to the packages are held on the packages along at least a part of the transport track by the at least one positioning belt and a second positioning belt, the second positioning belt extending at least in sections along the transport track such that the additional elements applied to the packages are held on the packages along at least a part of the transport track by the positioning belt and the second positioning belt is provided respectively on opposite sides of the applicator.

11. The application device according to claim 1 ,
wherein
the at least one positioning belt comprises holding cams for holding the additional elements on the packages and in that, the holding cam extends from a belt section extending at least substantially in the transport direction of the positioning belt to the side and at least in sections in the direction of the transport track of the packages.

12. The application device according to claim 1 ,
wherein
a belt section of the positioning belt extending at least substantially in the transport direction of the at least one positioning belt, at least one holding cam of the positioning belt and a package respectively define at least one receiving space for an additional element at least in sections along the transport track of the packages, and in that, the belt section and the holding cam are in contact, respectively in sections along the transport track of the packages, on different side surfaces of the package.

13. The application device according to claim 1 ,
wherein
the packages comprise at least one surface section oriented at least in sections along the transport track inclined in the transport direction of the transport track and inclined in at least one transport direction of the at least one positioning belt, and in that the application device is provided for attaching the additional element on the inclined surface section, and in that the holding cams are provided for holding the additional elements on the inclined surface sections.

14. The application device according to claim 13 ,
wherein
the at least one inclined surface section is inclined at least in sections along the transport track of the packages by between 25° and 65 in relation to the transport track and/or the at least one transport direction of the at least one positioning belt.

15. The application device according to claim 13 ,
wherein
the at least one inclined surface section is provided in the edge region of the packages, and in that the inclined surface section is inclined between 25° and 65° in relation to at least one adjacent side surface of the package.

16. The application device according to claim 1 ,
wherein
the at least one positioning belt and the transport track of the packages approach one another in sections along the transport direction, the approaching of the positioning belt and the transport track of the packages is provided subsequently to the point of application of the additional elements to the packages.

17. A method for applying straws, to cardboard composite packages having an application device according to claim 1 ,
in which the straws guided toward the packa
