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, 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,

characterised in that

a transfer means is provided for picking up the additive packaging material relayed from the supply means and for accelerating the picked up additive packaging material to a speed adapted to the application means in such a way that the transfer means delivers the additive packaging material to the application means at a circumferential speed, which at least substantially corresponds to the speed at which the additive packaging materials are applied to the packages.

2. The device according to claim 1,

characterised in that

the supply means for the stepwise transport of the additive packaging material is designed to be cyclically drivable.

3. The device according to claim 1,

characterised in that

the separating organ is designed to be cyclically drivable, in particular synchronously with the supply means.

4. The device according to claim 1,

characterised in that

the supply means comprises a rotatable carousel with recesses distributed over the circumference for the transport of the additive packaging material to the separating organ and for relaying the additive packaging material.

5. The device according to claim 4,

characterised in that

radial notches are incorporated between the recesses for receiving the separating organ during separation.

6. The device according to claim 1,

characterised in that

the application means comprises an application wheel which is drivable preferably at an at least substantially constant rotational speed, in particular at a circumferential speed at least substantially corresponding to the transport speed of the packages.

7. The device according to claim 1,

characterised in that

the transfer means comprises a transfer element which can be pivoted at variable speeds and/or a transfer wheel which can be rotated at variable circumferential speeds.

8. The device according to claim 7,

characterised in that

the supply means, in particular a carousel of the supply means, and the transfer means, in particular a transfer wheel of the transfer means, are designed for picking up the additive packaging material from the supply means to the transfer means at least approximately at the same speed from the supply means and the transfer means at a pick-up position.

9. The device according to claim 1,

characterised in that

the transport means is associated with at least one adhesive application means for gluing the packages supplied to the application means along the package transport path.

10. A method for separately applying additive packaging material supplied in an additive packaging material continuous belt, preferably wrapped straws, to packages, in particular cardboard composite package, preferably using a device according to claim 1,

characterised by the steps of

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

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

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

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

delivering the accelerated additive packaging materials to the application means at a speed adapted to the application means,

delivering the accelerated additive packaging materials from the transfer means to the application means at a circumferential speed, which at least substantially corresponds to the speed at which the additive packaging materials are applied to the packaging, and

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

11. The method according to claim 10,

characterised in that

the supply means and the transfer means are driven cyclically, and/or in that the application means is driven continuously, in particular at an at least substantially constant speed.

12. The method according to claim 10,

characterised in that

the supply means stands still when separating the additive packaging material using the separating organ and/or when relaying the additive packaging material.

13. The method according to any claim 10,

characterised in that

the transfer means picks up the separated additive packaging materials, preferably directly, from the supply means at the pick-up position, and/or preferably directly delivers said separated additive packaging material at a delivery position to the application means and/or in that the additive packaging materials are relayed from a carousel of the supply means to a transfer wheel of the transfer means in particular by rotating the carousel and the transfer wheel, and/or from the transfer wheel of the transfer means to an application wheel of the application means, in particular by rotating the transfer wheel and the application wheel.

14. The method according to claim 10,

characterised in that

the application means an application wheel rotating at an at least substantially constant speed for picking up and applying the additive packaging material and in that the additive packaging materials, with the transfer means, are accelerated at least substantially to the circumferential speed of the application means until the delivery of the additive packaging material to the application means.

15. The method according to claim 10,

characterised in that

the additive packaging materials are delivered from the transfer means to the application means at a circumferential speed, which at least substantially corresponds to the circumferential speed, at which the additive packaging materials are applied to the package.
