Definitions

  • the invention relates to a direct printing machine and a method for printing containers with direct printing according to the features of the preamble of claim 1 or 13.
  • the direct printing machine comprises a transport device for transporting the containers and direct print heads for applying the direct print during transport.
  • a direct print head is, for example, an ink jet print head which has a large number of print nozzles which are typically arranged in one or more rows (for example 1000 to 5000 each in 1 to 4 nozzle rows).
  • a two-dimensional print image there is also a relative movement between the container surface and the direct print head, essentially perpendicular to the rows of nozzles.
  • the print image itself is available as digital information in a computer control for controlling the direct print head. Furthermore, the printing ink is cured in a subsequent curing station via UV or other energy beams, such as electron beams, by crosslinking.
  • UV or other energy beams such as electron beams
  • the disadvantage here is that the ink droplets emitted by the direct print heads are blown away by the wind and the quality of the printed image is reduced as a result. As a result, higher speeds or outputs are difficult or impossible to achieve and use in higher humidity is not possible. In addition, dust particles or the like can settle on the containers, further degrading the print image or clogging the print nozzles. In addition, in the case of the known direct printing machines, an ink mist extraction system is necessary in order to collect the ink mist produced by the relative wind.
  • Another disadvantage is that the operating personnel must be extensively protected against UV radiation for curing the printing ink, against ink particles, ozone, etc.
  • the DE 10 2013 208 065 A1 discloses a rotary machine for printing on containers.
  • the EP 2 743 087 A1 discloses a fairing printing press.
  • the DE 10 2013 208 065 A1 discloses a rotary machine for printing on containers.
  • the DE 10 2013 214 935 A1 discloses a printing station and method for direct container printing.
  • the invention provides a direct printing machine for printing containers with the features of claim 1.
  • Advantageous developments of the invention are specified in the dependent claims.
  • the direct print is also applied in a vacuum. Consequently, even at high speeds, there is no headwind and thus no blowing of the pressure drops. Furthermore, no ink mist or the like is generated and the printing is independent of the environmental conditions, such as temperature and humidity. Furthermore, no dust develops within the treatment chamber, which could contaminate the printed image or clog the printing nozzles. In addition, the treatment chamber protects the operator from odors, any radiation, ozone and/or paint particles.
  • the direct printing machine can be arranged in a beverage processing plant.
  • the direct printing machine can be downstream of a filling system for filling a product into the containers and/or a closing device.
  • the direct printing machine can also be installed upstream of the filling process and/or directly downstream of a container production process. Detached from this, it can also be a direct printing machine that is not assigned to any system, but works in so-called stand-alone mode.
