Abstract

Presented and described are a device for separately applying additive packaging material, preferably wrapped straws, supplied as an additive packaging material continuous belt, to packages, in particular cardboard composite packages, having a separating organ for separating the additive packaging material of the additive packaging material continuous belt, a supply means for supplying the additive packaging material continuous belt to the separating organ and for relaying the additive packaging material separated by the separating organ, an application means for applying the separated additive packaging materials to the packages and a transport means for transporting the packages along a package transport path to the application means. So that the separation and application of the additive packaging materials can be carried out quickly, with high quality and reliably, it is provided that a transfer means is provided for picking up the additive packaging material relayed from the supply means and for accelerating the transferred additive packaging material to a speed adapted to the application means.

Claims

1. A device for separately applying additive packaging materials, supplied as an additive packaging material continuous belt, to packages, the device having a separating organ for separating the additive packaging materials of the additive packaging material continuous belt, a supply section comprising a carousel which rotates about a central axis for supplying the additive packaging material continuous belt to the separating organ and for relaying the additive packaging materials separated by the separating organ, an application section consisting of an application wheel with an applicator rotating about an axis of rotation for applying the separated additive packaging materials to the packages, and a transport section comprising a transport belt provided with cams for transporting the packages along a package transport path to the application section,

wherein a transfer section comprising a transfer wheel rotatable about a central axis is provided for picking up the additive packaging materials relayed by the supply section and for rotationally accelerating the picked up additive packaging materials to a speed adapted to the application section in such a way that the transfer section delivers the additive packaging materials to the application section at a circumferential speed which corresponds to a speed at which the additive packaging materials are applied to the packages.

2. The device according to claim 1, wherein the supply section is for stepwise transport of the additive packaging materials and is designed to be cyclically drivable.

3. The device according to claim 1, wherein the separating organ is designed to be cyclically drivable synchronously with the supply section.

4. The device according to claim 1, wherein the carousel has recesses distributed over its circumference for transport of the additive packaging materials to the separating organ and for relaying the additive packaging materials.

5. The device according to claim 4, wherein radial notches are incorporated between the recesses for receiving the separating organ during separation of the additive packaging materials.

6. The device according to claim 1, wherein the application wheel is drivable at a circumferential speed corresponding to a transport speed of the packages.

7. The device according to claim 1, wherein the transfer wheel can be rotated at variable circumferential speeds.

8. The device according to claim 7, wherein the additive packaging materials are transferred from the carousel of the supply section to the transfer wheel of the transfer section at a pick-up position while the carousel and the transfer wheel move at the same speed.

9. The device according to claim 1, wherein the transport section is associated with at least one adhesive application section for gluing the packages supplied to the application section along the package transport path.

10. A method for separately applying additive packaging materials, supplied in an additive packaging material continuous belt, to packages, using the device according to claim 1, the method comprising the steps of:

supplying an additive packaging material continuous belt to the separating organ by means of the supply section,

separating additive packaging materials of the additive packaging material continuous belt on the supply section by means of the separating organ,

relaying the separated additive packaging materials by means of the supply section,

picking up and rotationally accelerating the separated additive packaging materials to a speed adapted to the application section by means of the transfer section,

delivering the accelerated additive packaging materials from the transfer section to the application section at a circumferential speed corresponding to a speed at which the additive packaging materials are applied to packages, and

applying the additive packaging materials by means of the application section to packages moved past the application section along a package transport path by the transport section.

11. The method according to claim 10, wherein the supply section and the transfer section are driven cyclically, and/or in wherein the application section is driven continuously constant speed.

12. The method according to claim 10, wherein the supply section stands still when separating the additive packaging materials using the separating organ and/or when relaying the additive packaging materials.

13. The method according to claim 10, wherein the transfer section picks up the separated additive packaging materials directly from the supply section at a pick-up position,

and/or wherein the transfer section directly delivers said separated additive packaging materials to the application section at a delivery position,

and/or wherein the additive packaging materials are relayed from the carousel of the supply section to the transfer wheel of the transfer section by rotating the carousel and the transfer wheel,

and/or wherein the additive packaging materials are relayed from the transfer wheel of the transfer section to the application wheel of the application section by rotating the transfer wheel and the application wheel.

14. The method according to claim 10, wherein the application wheel rotates at a constant speed for picking up and applying the additive packaging materials and wherein the additive packaging materials, by means of the transfer section, are accelerated to a circumferential speed of the application section until the delivery of the additive packaging materials to the application section.

15. The method according to claim 10, wherein the circumferential speed at which the additive packaging materials are delivered from the transfer section to the application section corresponds to a circumferential speed at which the additive packaging materials are applied to the packages.
