Definitions

  • Printing machine with at least one print head
  • the invention relates to a printing machine with at least one print head according to the preamble of claim 1.
  • a device and a method for printing an image on a non-cylindrical, circularly symmetrical surface of an object are known, printing using a print head with ink jet nozzles with tips in a nozzle plane by rotating the object about the longitudinal axis of the surface occurs while a print engine controller drives the print head in space and controls the operation of the nozzle tips within a predetermined print gap along the surface to print the image.
  • a three-dimensional printer which carries out predetermined printing by ejecting an ink from a print head onto a surface of an object to be printed.
  • This printer includes a holding chuck that holds the object to be printed; first to third support elements that hold the holding chuck to be movable in space; a printhead carriage having a front end supporting the printhead to be linearly movable relative to the object to be printed held by the holding chuck; and a drive device oscillating right and left.
  • the oscillating drive device rotates and moves the print head in a right-left direction, centering an up-and-down axis of rotation to perform desired printing while ejecting the ink from the print head.
  • US 2013/0215196 A1 and US 2005/0243112 A1 each describe a printing machine with several surfaces of an article in an inkjet Printheads for printing processes are known, these printheads being arranged in a row along a longitudinal axis of the article to be printed, with a respective direction of the ink ejected from the respective printing nozzles of these printheads and the longitudinal axis of the article to be printed being in the same printing plane and the respective direction of the ink ejected from the respective print nozzles of these print heads is directed perpendicular to the printing surface of the article in question.
  • the invention is based on the object of creating a printing machine with at least one print head, in particular to print a conical article with a print image in good print quality.
  • the proposed printing machine can also be used to produce an article, in particular a glass article is designed as a rotating body, but does not have an ideal cylindrical shape, but is rather conical and therefore has the shape of a cone or a truncated cone, can be printed without distortion and with precise registration.
  • the distortion-free and register-accurate printing of the lateral surface of a conical rotating body is ensured by the fact that the at least one print head in the printing process is arranged perpendicular to the surface of the article in question and a longitudinal sectional plane running through the relevant print head intersects a rotation axis of the article in question.
  • a body of revolution is a body whose surface is formed by rotating a generating curve around an axis of rotation.
  • the large tolerances of hollow bodies to be printed made of glass compared to other printing materials require a much larger spacing of the print head in question from the surface of the hollow body in question to be printed.
  • the ink droplets ejected by the print head in question therefore have to travel a significantly longer distance.
  • the relevant ink droplets must be made larger than when printing on other printing materials, ie when printing on hollow glass bodies, the ink droplets each contain a comparatively larger amount of ink. This means that these ink droplets have to be subjected to higher kinetic energy in order to overcome the air resistance on their flight path.
  • the increased energy requirement to be processed by the print head in question now means that the print head in question can only be designed with a very limited print width, this print width being currently Commercially available print heads are typically 70 mm.
  • a further difficulty in creating a print image with a print length that exceeds this print width is that, due to their housing-like enclosure, these print heads cannot be lined up in such a way that their respective print widths would seamlessly complement each other to form a print length that exceeds the individual print width. Instead, it is necessary to arrange such print heads offset from one another in different printing planes. For distortion-free and accurate printing of the lateral surface of a conical rotating body, this requires tracking in the respective printing position of the print head in question.
  • register - also called color register - refers to the matching and/or overlapping of individual printing colors in multi-color printing.
  • the register therefore refers to the correct printing in several consecutive printing processes.
  • the four process colors cyan, magenta, yellow and black are usually printed one after the other in the correct position and at least partially on top of each other.
  • the printing colors printed one after the other and sometimes on top of each other then, taken as a whole, result in the printed image to be printed. If these printing colors do not have exactly the right balance to each other, the printed image appears distorted, i.e. H. Blurry, out of focus or with color shifts, which in any case has a negative effect on the quality of the print image to be printed.
  • the term “article to be printed” here means a real three-dimensional object that occupies a space and has interfaces and a mass.
  • the article to be printed is - as mentioned - preferably designed as a hollow body, in particular as a glass article.
  • the article to be printed has a center of mass and a longitudinal extent or longitudinal axis with which its axis of rotation corresponds in the printing process.
  • a three-dimensional orthogonal coordinate system anchored in the center of mass of the article to be printed or in the center of mass of the print head in question has three axes that are orthogonal to one another, namely a longitudinal axis and a transverse axis and a vertical axis.
  • a rotational movement about the respective longitudinal axis is called rolling and a rotational movement about the respective transverse axis is called pitching and a rotational movement about the respective vertical axis is called yaw.
  • the following is based on an industrial printing process in which at least one print head printing in an inkjet printing process, preferably several print heads each printing in an inkjet printing process, print on a surface of the relevant article in a printing machine.
  • Each of these print heads is enclosed in a housing in the range of a few millimeters, e.g. B. between 1 mm and less than 8 mm distance from the surface to be printed of the article in question at least one row of printing nozzles arranged next to one another, each of these printing nozzles being designed to eject ink and a length of the relevant row of printing nozzles being the printing width of the relevant printhead is defined.
  • each of the print heads that print on this article using an inkjet printing process is arranged along the longitudinal axis of the article to be printed and extends over a section of this article to be printed. Since a longitudinal extent of the article to be printed and thus a length of the printed image to be created is often greater than a print width of the print head in question, in the proposed printing machine several print heads with their respective printing width are arranged in a row along the longitudinal axis of the article to be printed.
  • a respective direction of the ink ejected from the respective printing nozzles by the possibly several print heads arranged in a row along the longitudinal axis of the article to be printed and the longitudinal axis of the article to be printed are in the same plane, which is also referred to as the printing plane, the respective Direction of the from the The ink ejected from the respective printing nozzles is directed perpendicular to the printing surface of the article in question to produce a high-quality, in particular distortion-free printed image.
  • several different printing planes are provided with respect to the surface to be printed of the article in question, with the printing nozzles arranged in the different printing planes each eject inks of different colors from one another, e.g.
  • Inks in the process colors cyan, magenta, yellow and black. Since these printing planes each intersect the longitudinal axis of the article to be printed, immediately adjacent printing planes form a V-formation.
  • a series of several articles with the same geometry are printed in the printing press, the geometry of which has a large spread in the respective tolerances.
  • Fig. 1 shows an arrangement of several print heads that collectively print on an article
  • FIG. 2 shows a first exemplary embodiment of a holder that changes the position of the print heads in space
