Equipment for printing on containers

摘要

The invention relates to equipment for printing on containers (B), such as bottles, having a printed design (D) on at least one printing machine having at least one print head (1), and is characterized in that the at least one print head (1) is automatically adjustable by means of an electrical controller. An adjustment value from the controller moves the print head (1) according to spatial co-ordinates and/or an angular position into a position that is determined or calculated by means of a measuring device having e.g. sensors from the surface contour and the position relative to the print head (1) of the container (B) to be printed upon.

主权项

1. An apparatus for printing a design on a container, said apparatus comprising a first rotary printing machine, a second rotary printing machine that follows said first rotary printing machine, and a controller that operably interlinks said first rotary printing machine and said second rotary printing machine, wherein each of said first and second rotary printing machines comprises a plurality of printing stations, wherein each printing station from said plurality of printing stations comprises a print head that has an adjustable position and orientation relative to a container, and a measuring device configured to determine said position and orientation of said print head relative to said container, wherein said measuring device comprises sensors that are arranged such that a distance between said print head and said container is continuously measurable, wherein said measuring device is configured to receive, from said sensors, information representative of said position and orientation of said print head relative to said container and to provide said information to said controller, and wherein said position and orientation of said print head relative to said container is adjustable by said controller based at least in part on said information provided by said measuring device.
