Abstract

The invention relates to a method for equipping containers (2) with equipping features (3), the containers (2), which are situated on at least one transport element (4) of a transport section (7, 4, 12), being moved past at least one processing station (8-12) of an equipping system (20) in order for each container (2) to be supplied with at least one equipping feature (3), characterized in that the actual geometry or shape of the container (2) is detected at least in areas that are relevant for equipping, and the equipping process is then adapted by controlling and/or regulating and/or adjusting the equipping system (20) and/or the location and/or orientation of the container (2) to the detected actual geometry or shape of the container (2).

Claims

1. A method for equipping containers with equipping features, the containers, which are situated on at least one transport element of a transport section being moved past at least one processing station of an equipping system in order for each container to be supplied with at least one equipping feature, said method comprising:

capturing the actual geometry or shape of the containers, at least in areas thereon that are relevant for equipping, and

adapting the equipping process to the actual geometry or shape of the containers by controlling and/or regulating and/or adjusting the equipping system and/or the location and/or orientation of the containers.

2. The method according to claim 1, wherein capturing the actual geometry or shape of the containers at least in areas thereon that are relevant for equipping comprises

capturing with at least one sensor unit, the sensor unit being disposed such that the container arrives at the sensor unit prior to entering the equipping system, and

controlling the equipping process based at least in part on data from the sensor unit.

3. The method according to claim 1, further comprising generating control data to control the equipping process by comparing the captured actual geometry or shape with a set geometry or shape.

4. The method according to claim 1,

further comprising assigning the respective actual geometry or shape of the containers, at least in areas thereon that are relevant for equipping, to groups of container geometries or tolerance groups, and

wherein adapting the equipping process takes place during the equipping process according to a program specified for the respective group.

5. The method according to claim 4, wherein the equipping system has several processing stations, at least one of which is assigned to each group, and wherein adapting the equipping process to the actual geometry or shape takes place at the at least one processing station assigned to an actual geometry or shape group.

6. The method according to claim 1, wherein adapting the equipping process to the actual geometry or shape comprises

changing the working method by altering the setting and/or the orientation of the at least one processing station in relation to the containers moved past the at least one processing station.

7. The method according to claim 6, wherein the equipping system has at least two processing stations, and wherein operation of the processing stations in the application of the respective equipping element to the containers and adapting the equipping process to the actual geometry or shape take place at different times at different processing stations.

8. The method of claim 1, wherein when there are several equipping elements to be applied to each container, capturing comprises capturing the actual geometry or shape of each area of each container relevant for equipping and, for each equipping element, adapting the equipping process comprises adapting to the respective actual geometry or shape of the area relevant for equipping which is assigned to the equipping element.

9. The method of claim 1, further comprising:

using a transport system formed, at least partially, by a rotor driven in rotation about a vertical machine axis, with which the containers are moved past on the equipping system which does not move together with the rotor, and

wherein capturing the actual geometry or shape of the containers on areas thereon that are relevant for equipping takes place on the rotor or on a transport element preceding the rotor in the direction of transport of the transport system.

10. The method of claim 1, wherein equipping containers comprises applying labels, and wherein the at least one processing station of the equipping system is a labelling device.

11. The method of claim 1, wherein the actual the set geometry or shape of the containers, at least in the areas thereon that are relevant for equipping purposes, is a form that is rotationally symmetrical in relation to a container axis.

19. The method of claim 1, wherein equipping containers comprises applying printed images onto the containers, and wherein the at least one processing station of the equipping system is at least one printing station and/or a printing head, and wherein adapting the equipping process comprises at least one of electronically compressing, rotating or stretching electronic artwork masters.

12. A device for equipping containers with equipping features, said device comprising:

at least one transport section;

at least one processing station of an equipping system provided on the transport section past which the containers are moved in order to apply at least one equipping feature;

on the transport section, means for capturing the actual geometry or shape of the containers at least in areas thereon that are relevant for equipping purposes; and

means for adapting the equipping system and/or the location and/or orientation of the containers to the captured actual geometry or shape of the respective container.

13. The device according to claim 12,

wherein the means for capturing comprises at least one sensor unit for capturing the actual geometry or shape,

wherein said sensor section is arranged on the transport section such that the container arrives at the sensor unit prior to entering the equipping system, and

wherein the means for adapting comprises a control system for controlling the equipping process taking into account data from the sensor unit.

14. The device according to claim 13, wherein the control system is configured to generate control data to control the equipping process by comparing the captured actual geometry or shape with a set geometry or shape.

15. The device according to claim 12, wherein the at least one some-ewe processing stations are designed is configured to change at least one of a working method, a setting, and an orientation as a function of the actual geometry or shape.

16. The device according to claim 13,

wherein the transport section is partly formed by a rotor driven in rotation about a vertical machine axis, with which the containers are moved past the equipping system which does not move together with the rotor, and

wherein the sensor unit is provided on the rotor or on a transport element preceding the rotor in the direction of transport of the transport systems.

17. The device according to claim 12, wherein the at least one processing station of the equipping system is a labelling device.

18. The device according to claim 12, wherein the at least one processing station of the equipping system is a printing station and/or a printing head, and wherein the means for adapting comprises electronic means for at least one of compressing, rotating or stretching electronic artwork masters.

20. The device according to claim 16, wherein the sensor unit is provided on one of a container intake and a transport star wheel.
