Definitions

  • the present invention relates to a printer referred to in the preamble of claim 1 Art.
  • a single-pass inkjet printer with a printing module and an extension system is known.
  • the extension system comprises two opposing telescopic rails, which are connected to the printing module and by means of which the printing module relative to the housing of the printer between a solid and a retracted position is displaceable storable.
  • the telescopic rails are designed for the one-sided extension of the printing module.
  • the printing module of the single-pass printer comprises at least one, but typically a plurality of printheads each having at least one row of nozzles for printing a medium by ejecting ink drops.
  • WO 2011 157281 describes a single pass ink jet printer having a track for guiding a print medium along a direction of travel as well as having a number of printhead modules extending transversely across the track. It is provided that the printhead modules are arranged in each case substantially vertically adjustable self-aligning in a device-fixed printing position and reversibly removable in the device fixed printing position. Such a single-pass inkjet printer offers the potential for easy manual replacement of printhead modules, reducing downtime.
  • JP 2003 211053 A describes an apparatus for coating a surface of an object to be coated, such as a semiconductor or liquid crystal substrate, with a cover coating or the like having a uniform film thickness.
  • WO 2015 EPO 1557 describes a printing module comprising a front mounted assembly for mounting a printhead in an ink jet printer, the printing module being spaced relative to a tray, and the assembly comprising a support frame having an opening extending through the support frame is provided for the recording / dispensing of the print head, wherein the assembly has means for mounting the print head, which allow a front-side receiving the same in a repair position of the printing module relative to the storage device.
  • a single-pass printer is understood as meaning a printer having a printing module for printing on the medium, in which the medium is continuously moved in the operating mode and the printing module sees a single area of the medium, wherein the printing module does not act according to the known scanning method is operated, but essentially is arranged stationary.
  • Such single-pass printers with pullout systems have the difficulty of having the print engine difficult to properly reposition back to the predetermined print position after pullout. This is especially important because only in the correct printing position can an image be printed with the desired print quality.
  • at least four print modules are arranged one after the other in the feed direction, one for each basic color, including black.
  • the printing quality deteriorates with increasing distance of the printing modules from each other when printing a medium with a single-pass printer, since due to the inevitable tolerances, the medium has a side run perpendicular to the transport direction.
  • the invention is therefore based on the object to provide a single-pass printer with a simple extension system, with which the above problems can be at least reduced.
  • a single-pass printer with at least one printing module for printing a medium and an extension system is presented, which can be coupled to the printing module via at least one coupling means, wherein the printing module comprises at least one nozzle row and wherein the extension system is designed such that the pressure module in the coupled state relative to a frame of the single-pass printer between a retracted position and a variable selectable extended position can be moved.
  • the printing module can be decoupled from the extraction system at least if ink droplets are to be printed on a medium by means of the printing module via the at least one nozzle row, wherein the printing module can be stored in a predetermined printing position on a support bracket of the frame in a decoupled state from the extraction system.
  • the inventive single-pass printer advantageously allows a more compact design than the known single-pass printer with pull-out system.
  • a single-pass printer is provided with at least one printing module for printing a medium and an extension system which can be coupled to the printing module via at least one means for coupling, wherein the printing module comprises at least one nozzle row and wherein the extension system is designed such that the print module can be moved in the coupled state relative to a frame of the single-pass printer between a retracted position and a variably selectable extended position, wherein the Auszusgsystem is designed such that the print module in coupled to the extension system Condition with the extension system in two opposite directions and thus two-sided relative to the frame extractable and can be inserted.
  • the objective technical problem of the second aspect of the invention resulting from the alternative solution compared to the first aspect of the invention is likewise to provide a single-pass printer with a simple extension system with which the abovementioned problems can at least be reduced.
  • Such a printer can also be advantageously a more compact design than the known single-pass printer.
  • the invention is defined by the main claim 1.
  • a single-pass printer is shown with a printing module 101 for printing on a medium 103 and an extraction system.
  • the extension system comprises a relative to the frame 107 of the printer (out of the plane) extendable guide unit 111 which is formed as a metal sheet with a hat profile, and a guide arrangement which is formed as opposed first and second rotatably mounted rollers (113, 113 ').
  • the respective first and second rollers (113, 113 ') together define a guide plane along which the plate is slidably mounted.
  • the sheet is releasably coupled via means for coupling 105 with the printing module 101.
  • the single pass printer comprises a support device 104 by means of which the medium 103 can be transported in the transport direction X.
  • the extension system is designed to be able to move the printing module 101 in the coupled state relative to the frame 107 of the single-pass printer between a retracted position and a variably selectable extended position (not shown).
  • the printing module 101 is at least then decoupled from the extension system if the medium 103 is to be printed by means of print module 101 via the nozzle row by means of ink drops (not shown), wherein the printing module 101 in the decoupled state in a predetermined printing position on a support bracket 109 of Rack 107 is stored stationary.
  • FIG. 2 is the most preferred embodiment of the inventive single-pass printer FIG. 1 in the illustrations (CD) shown in front view.
  • the extension system is mounted with the printing module 201 in the coupled state in an extended position.
  • the printing module 201 comprises a plurality of print heads 219 each having at least one nozzle row (not shown).
  • the Printheads 219 are connected via supply lines 217 to an ink tank 215 housed in the print module 201.
  • the printing module 201 is first moved back into the retracted position with the aid of the extension system and then moved to a printing position by being decoupled from the metal sheet and stationarily mounted on the support bracket 209 (FIG )
  • the pressure module 201 in Figures C and D comprises at their opposite ends respectively means for coupling 205, which are formed in the example as a motion screw, which are formed on each provided in the guide unit 211 openings with corresponding provided on the pressure module 201 mother screws as counterparts cooperating in such a way that together they serve for converting a rotational movement of the displacement screw into a longitudinal movement, that is to say, for example, raising the pressure module 201.

  • the printing module 101 can be decoupled from the separation system at least if ink droplets are to be printed on a medium 103 by means of the printing module 101, wherein the printing module 101 is stationary in a predetermined printing position on a support holder 109 of the frame 107 in the decoupled state from the extraction system can be stored.
  • the advantage achieved with the invention consists in the fact that the pressure module 101 in the decoupled state is not susceptible to mechanical inadequacies of the guide carriage. Incidentally, this is also the reason why in contrast to the prior art printer according to the invention simpler and less expensive extraction systems and thus printers can be used.
  • the extension system is designed such that the printing module 101 in the coupled state with the extension system in two opposite directions and thus two-sided relative to the frame 107 and retractable is inserted.
