Printing device for containers

摘要

A printing device for containers, such as bottles, cans or cups, with a screen to apply a screen print onto the containers, where a squeegee holding device that is guided by a continuous track holds an squeegee in such a way that while the printed image is being applied to the container, one end of the squeegee scrapes across the screen and forces ink through the screen onto one of the containers, and where the distance between the end of the squeegee and the squeegee holding device varies. Also, a container handling device, in the manner of a bottling plant, with such a printing device and a mechanical turret designed to guide the containers to a surface of the container contact device facing away from the squeegee. Also, a method for applying ink to containers in accordance with a screen printing principle.

主权项

1. A printing device for containers, comprising a screen to apply a screen print onto the containers, a squeegee-holder that is guided by a continuous track and holding a squeegee in such a way that during the container printing process one end of the squeegee scrapes across the screen, thus forcing ink through the screen and onto one of the containers, and the distance between the end of the squeegee and the squeegee-holder is variable, wherein the squeegee-holder is connected to a first coupling location on a first curved track in a manner allowing the squeegee-holder to travel along the first curved track, and also connected to a second coupling location on a second curved track that encompasses the first curved track, in a manner allowing the squeegee-holder to travel along the second curved track, wherein the first and the second curved tracks predetermine the position of the squeegee, wherein the squeegee-holder is movable around an axis of rotation of a rotating distributor, and wherein the rotating distributor is equipped with several arms, and the first curved track and the second curved track are configured in such a way that the angle between the squeegee and the respective arm leads to the respective squeegee-holder changes during the rotation of the squeegee-holder around a center of rotation.
