Problems solved by technology

[0003] A particular problem encountered especially in printing units for printing containers with print heads working according to the inkjet printing or Tonejet principle is that during the printing process part of the printing ink does not reach the outer surface area of ​​the container to be printed, but sprays into the surrounding air in which an aerosol comprising finely distributed ink or printing ink particles is formed
Atomized particles of these inks or printing inks are particularly undesirabl

Embodiment Construction

[0013] exist Figure 1-4 The printing unit, generally designated 1 , is used for the direct printing of containers, which in the depicted example are bottles, in particular PET bottles 2 .

[0014] The printing unit 1 comprises, inter alia, a printing wheel or runner 3 which can be driven in rotation about a vertical machine axis Z (arrow A) and which, on its periphery, runs around the machine at uniformly distributed angular distances The axis Z configures a plurality of processing or printing positions 4 .

[0015] The bottles 2 to be printed are fed to the container inlet of the printing unit 1 by means of an external conveyor 6, shown as an infeed star 5, the bottles 2 to be printed are upright, i.e. their bottle axes are directed vertically, and Following one another in the conveying direction B of the conveying device 6 , each bottle 2 reaches the printing station 4 via an infeed stand 5 . The already printed bottles 2 are respectively moved away from the printing stat...

Abstract

The invention relates to a printing apparatus for printing bottles or similar containers, having several printing positions on a transport element, which can be driven in rotation, by which the printing positions and/or the containers are moved on a closed path of movement between at least one container take-up and at least one container drop, having rotating print heads for applying at least one print image, preferably multi-color, onto a region to be printed on the external container surface of the containers, in the event of relative movement of the external container surface and at least one print head, wherein at least one enclosure is present, into which each of the containers, which are provided at a print position, is housed during the printing process with at least the region to be printed thereof.

Description

technical field [0001] The invention relates to a printing device according to the preamble of claim 1 and thus in particular to a printing device for printing containers using at least one electronically or digitally triggerable printing head. Background technique [0002] It is basically known that the printing of containers, in particular the direct printing of containers, mainly comprises in the form of a preferably color printed image adapted to the container in question, constituting the basic elements of the assembly of the container in question, eg similar to conventional labels. In this regard, use is made of electrostatic printing heads, such as inkjet printing heads or printing heads known under the designation "Tonejet", i.e. operating according to the inkjet printing principle or the Tonejet principle and shown on the longitudinal axis of the printing head at At least one row of a plurality of individual nozzles is arranged consecutively on the active print head...
