Method for the positionally accurate application of labels, and labelling machine

Abstract

In a method for the positionally accurate application of labels (3) on bottles, cans or similar containers in relation to at least one container-typical design feature (4), the container-typical design feature of each container (2) which is moved past at least one camera (15) on a transport element (8) is detected using at least one image detection and processing system by way of said camera. The orientation and / or the actual form of the container-typical design feature on each container are / is detected by way of the image detection and processing system (4, 15) and the transfer instant of the label to the respective container is controlled from this in such a way that the label is positioned there in an optimum manner in relation to the design feature after the application.

Description

technical field

[0001] The invention relates to a method according to the preamble of claim 1 for applying labels to bottles or similar containers and a labeling machine according to the preamble of claim 16 for carrying out this method. Background technique

[0002] Bottles or similar containers are known which have typical configurational features of containers, for example typical geometrical features on their outer surface such as imprinted surfaces, decorations, indentations, raised characters and the like. When labeling these containers, it is necessary to apply the relevant label with high adhesion accuracy relative to the typical configuration features of the container, specifically also with the smallest possible size, for example within ± With an error in the range of 0.5mm, the efficiency can reach, for example, 60,000 labeled containers per hour.

[0003] Methods are known in which the containers fed to the container carrier of the labeling machine's rotor drive...
