Claims

1. A labeling station for use at a conveyor line, the conveyor line operable to convey an item to be labeled in a conveying direction at a conveying speed, the labeling station comprising:

a labeling member including a label holder configured to hold a label to be affixed to the item, the labeling member being configured to move at least the label holder at a matching speed in a matching direction and to affix the label to the item.

2. The labeling station according to claim 1, wherein the matching direction is a first degree of freedom of the labeling member, and wherein the labeling member is configured to move in at least one further degree of freedom for affixing the label.

3. The labeling station according to claim 2, wherein the further degree of freedom for affixing the label includes one or more of the following: translation along a transverse direction of the conveyor; translation along a vertical direction perpendicular to the conveyor; rotation around said first direction; rotation around a transverse direction of the conveyor; rotation around a vertical direction perpendicular to the conveyor; a combination thereof.

4. The labeling station according to claim 1 , wherein the labeling station is configured to obtain at least one of a speed signal indicative of the conveying speed or an arrival signal indicative of the arrival of an item to be labeled.

5. The labeling station according to claim 1, wherein the label holder is configured to affix the label using at least one of a contact-less application or a contact-based application.

6. The labeling station according to claim 1, further including one or more printing modules configured to print a label for the item, and wherein the labeling member is configured to move the label holder to the one or more printing modules to pick up the printed label.

7. The labeling station according to claim 1 , wherein the label holder is configured to move at the matching speed and the item is configured to move at the conveying speed over a first distance, wherein the first distance is predetermined or determined dynamically.

8. A labeling method for controlling a labeling station at a conveyor line, the conveyor line operable to convey an item to be labeled, the method comprising:

- obtaining a multi-dimensional representation of the item;

- determining a label target position in the representation; and

- controlling the labeling station to affix the label at said label target position on the item.

9. The method of claim 8, wherein the multi-dimensional representation of the item represents the item as a function of at least a longitudinal direction of the conveyor and a transverse direction of the conveyor.

10. The method of claim 8, wherein the representation of the item is indicative of at least one of the following: an orientation of the item, ph sical boundaries of the item, dimensioning of the item, weight of the item, surface properties of the item, or optical properties of the item.

11. The method of claim 8, wherein the determining of the label target position includes determining at least one of a spatial position for the label and a rotation of the label.

12. A labeling system for use at a conveyor line, the conveyor line operable to convey an item to be labeled, the system comprising:

- an imaging station configured to obtain a multi-dimensional representation of the item;

- a labeling station configured to affix the label at a target position on the item; and

- a control unit configured to determine said target position to be used by the labeling station based on said representation.

13. The system of claim 12, further including a conveyor unit adapted to form part of the conveyor line.

14. The system of claim 12, wherein the control unit is configured to control at least one conveying speed of the conveyor line to control a spacing between successive items on the conveyor line.

15. The system of claim 12, wherein the conveyor line is operable to convey the item to be labeled in a conveying direction at a conveying speed, and

the labeling station including a labeling member with a label holder configured to hold a label to be affixed to the item, the labeling member configured to move at least the label holder at a matching speed in a matching direction and to affix the label to the item.

16. The system of claim 15, wherein the matching direction is a first degree of freedom of the labeling member, and wherein the labeling member is configured to be moved in at least one further degree of freedom for affixing the label.

17. The system of claim 16, wherein the further degree of freedom for affixing the label includes one or more of the following: translation along a transverse direction of the conveyor; translation along a vertical direction perpendicular to the conveyor; rotation around said first direction; rotation around a transverse direction of the conveyor; rotation around a vertical direction perpendicular to the conveyor; a combination thereof.

18. The system of claim 15, wherein the labeling station is configured to obtain at least one of a speed signal indicative of the conveying speed or an arrival signal indicative of the arrival of an item to be labeled.

19. The system of claim 15, wherein the label holder is configured to affix the label using either a contact-less application or using a contact-based application.

20. The system of claim 15, wherein the labeling station includes one or more printing modules configured to print a label for the item, and wherein the labeling member is configured to move the label holder to the one or more printing modules to pick up the printed label.

21. The system of claim 15, wherein the label holder is configured to move at a matching speed and the conveyor is configured to move the item at the conveying speed over a first distance, wherein the first distance is either predetermined or determined dynamically.
