Definitions

  • the invention relates to a Druckkopfverstell adopted for an inkjet printer.
  • the invention is particularly concerned with the problem of influencing the print quality of a single-pass inkjet printer with thermal cycling of the attachment of the printheads in the Drucckopfmodulen.
  • the transversely mounted also called X direction
  • the transversely mounted printheads spray line by line ink onto the discontinuously transported medium in the direction of travel (also called the Y direction)
  • the printheads are in printhead modules mounted transversely across the entire width of the medium.
  • the print medium can be moved continuously in the direction of travel. While printing speeds of up to 2 m per minute are achieved with a conventional inkjet printer, printing speeds of more than 50 m per minute can be achieved with a single-pass inkjet printer.
  • a single-pass inkjet printer has multiple printhead modules mounted one behind the other in the direction of travel.
  • the printhead modules in each case a basic color, especially cyan, magenta and yellow, and optionally associated with black. For special print inserts additional printhead modules with a special color can be added.
  • a single-pass inkjet printer is particularly suitable for industrial use, where quantity must be printed and it therefore depends on a high throughput. Similarly, a single-pass inkjet printer is suitable for printing on large-area objects due to the high printing speeds. A single pass inkjet printer is therefore particularly suitable for industrial applications in the furniture or ceramics industry, where floor coverings such as laminates or ceramic tiles, countertops, moldings or the like are to be provided with a decor. In this case, a variety of inks are used, which are resistant to a later protective coating, etc., for example.
  • the single-pass inkjet printer is used even for small lot sizes, where the production of a pressure roller is not worthwhile.
  • a single-pass inkjet printer also makes it possible to individualize the decorations as well as so-called impossible decors that can not be achieved with rollers.
  • the single-pass ink jet printer is not limited to a constant repetition of a print pattern or repeat, as is the case with roller printing.
  • a single printhead module for a single-pass inkjet printer can reach dimensions of more than one-half to over one meter in the transverse direction and in height (also called the Z-direction).
  • the printheads grouped in the print heads of a printhead module can each have widths of up to several 10 cm. It is possible to achieve resolutions up to 600 x 600 dpi (dots per inch). Per printhead here several thousand nozzles are included. Large printhead modules or juxtaposing multiple printhead modules can achieve print widths of up to several meters.
  • the print heads in a print head module in the transverse direction (X-direction) and in the running direction (Y-direction) to store longitudinally displaceable.
  • the position of a printhead relative to the printhead module can then be adjusted by a corresponding displacement of the printhead.
  • the relative alignment of the printheads to the printhead module is done by means of a suitable tool before the printhead module with the then exactly positioned printheads is fixed in position in the single-pass inkjet printer.
  • a print head installed in fixed position relative to the printhead module is able to change its relative position to the printhead module during thermal cycling. Surprisingly, this can lead to permanent position changes of the print head, which lead to visible deviations in the printed image.
  • the object of the invention is therefore to provide a Druckkopfverstell pleased, on the one hand allows a positional positioning of the print head relative to a Drucckopfmodul, but on the other hand is as insensitive to thermal cycling as possible.
  • the invention is based in a first step on the knowledge gained by own observations that a pressure head module fixed in the print head module under thermal cycling its relative position to Drucckopf therefore also permanently changes, because after a temperature shift on return to the starting temperature is not guaranteed that the print head returns to its original position. For example, in the case of a print head clamped on both sides at the print head module with temperature-induced thermal expansion, it is not determined which of the fixing sides is the roll the fixed or the loser end takes over. When the printhead cools down to the original temperature, the restraint sides can also exchange their roles as fixed or as a loose end.
  • a printhead despite being clamped on the printhead module, is able to move in the ⁇ m range in the manner of a caterpillar movement, which may result in visible variations in the print image of the single-pass inkjet printer.
  • In-house investigations have shown true positional changes in the range of a few microns with clamped printheads during the operation of a single-pass inkjet printer.
  • the invention is based on the consideration of being able to position the print head positionably in the printhead module in its relative position while retaining the print head in such a way that a defined movable bearing is created, whereby the print head returns automatically to the ink after a temperature run repositioned original position.
  • the latter succeeds in that the print head is received by an adjustment adapter.
  • a loose end of the print head in the X direction is displaceable and rotatably mounted on the adjustment adapter about a rotation axis perpendicular to the XY plane.
  • a fixed end of the print head is received in an adjustable in the XY plane on Verstelladapter receiving means.
  • the printhead with the adjustment adapter, so the Druckkopfverstell responded as such, is attached to a printhead module.
  • the adjustment adapter on the printhead module screwed, glued, pressed or connected in any other way.
  • the position of the print head relative to the print head module in the transverse or X direction can be changed and the rotation angle of the rotation axis of the print head in the XY plane can be adjusted ,
  • the Losende of the print head is additionally slidably mounted in the X direction. Despite a two-sided restraint this is a migration of the printhead prevented after frequent thermal cycling.
  • a resultant of a temperature variation length difference of the print head relative to the print head module is received by the movable end in the X direction loose end. After a temperature change, the displaceable loose end of the print head returns to its original position. The printhead has not changed its location relative to the printhead module.
  • the proposed adjustment adapter makes it possible for the invention to align a print head with respect to a print head module and then fix it.
  • the defined assignment of a loose end avoids the migration of an aligned and fixed print head during frequent temperature changes.
  • the invention is basically suitable for any inkjet printer.
  • the invention is suitable for a single-pass inkjet printer, in which already changes in position of the print head in the micron range can have a negative impact on the quality of the printed image.
  • the receiving means may be adjustable or displaceable by means of a sliding, sliding or roller bearing or by means of a combination of different types of bearings on the adjusting adapter.

  • a turn rotatably mounted linear guide can be provided for the Losende.
  • the adjustment is preferably made essentially of a stretch-neutral material, which in a temperature range between 20 ° C and 50 ° C, in particular between 25 ° C and 40 ° C, a thermal expansion coefficient of less than 5 * 10 -6 K -1 , in particular less than 2 * 10 -6 K -1 .
  • a stretch-neutral material which in a temperature range between 20 ° C and 50 ° C, in particular between 25 ° C and 40 ° C, a thermal expansion coefficient of less than 5 * 10 -6 K -1 , in particular less than 2 * 10 -6 K -1 .

  • the fixation can be formed for example by a self-locking gear in a drive of the eccentric discs or by a mechanical or electrical blocking.
  • the fixed end of the print head can in principle be mounted firmly on the receiving means without a degree of freedom. However, since a pivoting of the print head around the axis of rotation at the loose end should remain possible, the fixed end of the print head is biased in an advantageous manner against the receiving means. By biasing the position of the fixed end can be maintained in the X-Y plane and at the same time ensure pivoting as a possible degree of freedom of the printhead without complex mechanical construction.
  • the bias voltage may be realized by suitable electromagnetic or mechanical biasing means.
  • mechanical biasing means in particular spring elements such as leaf springs or coil springs are.

  • the stop element is designed as a pin extending in the Z direction. In this case, the pin axis as such at the same time forms the axis of rotation for the loose end of the print head.
