Definitions

  • the invention relates to a single-pass inkjet printer according to the preamble of claim 1.
  • a single-pass inkjet printer is from WO 2014/185451 A1 famous.
  • the print heads mounted on a carriage spray ink droplets line by line in the transverse direction (also referred to as the X direction below) onto the medium that is transported discontinuously in the running direction (also referred to below as the Y direction), with a single pass -Inkjetdrucker mounted the print heads in print head modules of the type mentioned in the transverse direction (X-direction) over the entire width of the print medium.
  • the print medium is continuously moved in the running direction (Y-direction).
  • a conventional inkjet printer can achieve print speeds of up to 2 m per minute
  • a single-pass inkjet printer can achieve print speeds of more than 50 m per minute.
  • print head modules are mounted one behind the other in the running direction in a single-pass inkjet printer.
  • a primary color in particular cyan, magenta and yellow and possibly black, is assigned to each of the print head modules.
  • Printhead modules with a special color are added for special printing applications.
  • a single-pass inkjet printer is particularly suitable for industrial use in which bulk goods have to be printed and high throughput is therefore important.
  • a single-pass inkjet printer is also suitable for printing large objects due to the high printing speeds.
  • a single-pass inkjet printer is therefore particularly suitable for industrial applications the furniture or ceramics industry, where floor coverings such as laminates or ceramic tiles, worktops, moldings or the like are to be provided with a decor.
  • floor coverings such as laminates or ceramic tiles, worktops, moldings or the like are to be provided with a decor.
  • a wide variety of inks are used, which, for example, are resistant to a later protective coating.
  • the single-pass inkjet printer is also used for small batch sizes, where the production of a printing roller is not worthwhile.
  • a single-pass inkjet printer also allows the decor to be individualized as well as so-called "impossible" decors that cannot be achieved with rollers.
  • the single-pass inkjet printer is not limited to a continuous repetition of a print pattern or repeat, as is the case with a roller print.
  • a print head module for a single-pass ink jet printer achieves dimensions of more than 1 m in the transverse direction and in height, with a tendency towards even larger print widths and thus to a further increase in dimensions.
  • the individual print heads combined in a print head module are each up to a few 10 cm wide. Resolutions of up to 600 x 600 dpi (dots per inch) and more are achieved.
  • Each print head contains several thousand individual print nozzles. Accordingly, a plurality of print heads are arranged in the print head module, each of which in turn contains a large number of print nozzles.
  • the print head module as such extends in the transverse direction (X-direction) over the entire print width or over the entire width of the print medium.
  • Positional deviations of a few micrometers ( ⁇ m) are visible to the human eye in a printed image.
  • the individual print nozzles of a print head are only a few 10 ⁇ m apart.
  • the size of an image or print dot itself is in the range of 10 ⁇ m.
  • the print head modules can be used in the device-fixed printing position in a hanging, gravity-oriented orientation in the vertical direction (which in this case corresponds to the Z-direction).
  • the print head modules for example for the purpose of maintenance or replacement, are lifted together in a hanging orientation in the vertical direction (Z direction) from the device-fixed printing position on the single-pass inkjet printer.
  • the print head modules are stored essentially standing with respect to the vertical direction.
  • the wording "essentially” also includes the fact that when the print medium runs in an arc, individual print head modules are inclined by a polar angle relative to the Z direction in their device-fixed printing position, so that the print heads can also be parallel to the Z direction, particularly in the Y direction Print media are aligned. In the raised position, a cleaning module can be retracted under the print head modules, into which the print head modules are then lowered.
  • the invention is based on the object of achieving the longest possible service life for a single-pass ink jet printer of the type mentioned at the outset.
  • the single-pass inkjet printer of the type mentioned additionally comprises a storage area in which a number of print head modules are arranged in a respective storage position essentially in the Z direction (approximately vertical direction) and along the Z direction can be used reversibly and stored in a removable manner, with the print heads being accommodated in a protective cover by print head modules set in the storage position.
  • the invention is based on the consideration that the print head modules of the specified single-pass inkjet printer can be lifted in and out relatively easily, essentially in the vertical direction (Z-direction), due to their upright arrangement in the printing position readjustment is required. It is therefore possible to create an additional storage area for the print head modules in the single-pass inkjet printer itself, at a distance from the printing area, in which individual print head modules are safely parked if there is no printing operation or the respective print head module is not required for printing. For this purpose, a protective cover is included at the storage position for each printhead module, in which the printheads are accommodated to protect them from external influences.
  • the printheads are those housed in the protective cover Print head modules flushed with an inert gas.
  • an appropriate protective gas prevents the printing nozzles from oxidizing and/or drying out and sticking.
  • the protective gas is selected depending on the ink used in particular.
  • the printing nozzles are preferably flushed with an inert gas at a temperature between 15° C. and 30° C., advantageously between 20° C. and 24° C., which contains a relative humidity of 30% to 80%, advantageously 45% to 55%.
  • the invention recognizes that an easy change of the print head modules between the printing position and the storage position is made possible if a bearing corresponding to the printing position is created in the storage area. Therefore, the print head modules in the storage area corresponding to the printing area are also stored in a respective storage position standing essentially in the Z-direction and reversibly insertable and removable along the Z-direction.
  • a print head module is lifted out of the printing position or from the corresponding storage essentially in the vertical direction and brought into the storage area hanging and thus oriented by gravity. There it is raised accordingly when it reaches its storage position.
  • the print head module is just as easily changed from its storage position in the storage area to its printing position in the printing area.
  • the storage area is offset in the X or Y direction to the print area.
  • a lifting/lowering device is provided, which is designed for lifting the print head modules in and out in the Z direction and can be moved in the Y direction and/or in the X direction along the single-pass inkjet printer. This enables the individual print head modules to be moved in series or in parallel between the printing area and the storage area without requiring a great deal of space.
  • the storage area is offset in the Y direction to the printing area.
  • the print head modules are moved without changing their order by means of a lifting and lowering device in the Y direction between the printing area and the storage area in series.
  • An exchange of individual print head modules is preferably made possible in the storage area.
  • an orthogonal coordinate system is used here to describe the single-pass inkjet printer, with the three spatial directions being denoted by the X, Y and Z directions.
  • the directions used refer to the positive space sector. If a component is located "above” another component along one of the spatial axes, its corresponding axis section is larger. Conversely, the axial section of a component is smaller if it is "below” another component with respect to the spatial axis mentioned.
  • the X-direction is also referred to as the transverse direction.
  • the Y-direction is also called the running direction (of the print medium). In the mounted printer, the Z-direction essentially corresponds to the vertical direction.
  • the single-pass inkjet printer comprises a lifting/lowering device that can be moved in the Y-direction, which is designed to lift a print head module in and out in a freely oriented manner by gravity, essentially in the vertical direction.
  • mounting aids are preferably provided on each print head module, which engage in the corresponding fastening means of the lifting/lowering device.
  • the assembly aids are expediently designed as cable fasteners.
  • the respective print head module hangs in particular in a pendulum manner on the lifting/lowering device.
  • open bearings are provided for positioning a print head module of the single-pass inkjet printer in the printing area and in the storage area, into which corresponding bearing pieces arranged on the print head module sink with a self-adjusting alignment.
  • Catching means are preferably designed for self-adjustment on the print head module and on the single-pass inkjet printer, via which a pre-orientation of the suspended print head module, which is oriented by gravity, takes place with regard to the desired printing position or storage position when it is lifted.
  • the catch means in turn are preferably formed with a safety wedge a corresponding wedge shaft is received. In this case, the safety wedge and the wedge shaft are associated with the print head module or a frame construction of the single-pass inkjet printer or vice versa.
  • a cleaning device is arranged in the storage area, which comprises a number of squeegee carriers, each assigned to a storage position and preferably displaceable in the X-direction, which each carry a number of squeegees.
  • the cleaning device for each set print head module is provided with a squeegee carrier, through the movement of which, in particular in the X direction (transverse direction), the respective print heads are cleaned of dust and dirt residues as well as ink residues by means of the squeegees moving along.
  • the cleaning device and/or the squeegee carrier are designed to move the squeegees in the Y-direction.
  • the squeegees are preferably designed to wipe, suck or blow.
  • cleaning is done in an automated manner, in particular, while the print head modules are set in the respective placement position.
  • a sensor arrangement is preferably included for this purpose, which indicates the presence of a set print head module for each storage position. The starting process of the cleaning process is initiated if a presence signal is generated by the sensor arrangement for a storage position. External cleaning of the print head modules is not required. The intervals for external maintenance of the print head modules can be extended.
  • the cleaning device expediently includes a drive device for displacing one or each squeegee carrier, in particular along the X-direction.
  • the cleaning device comprises a separate drive unit for displacing a doctor blade carrier at each storage position. The displacement movement then only takes place for the squeegee carrier, which is located at the position of a set print head module, by appropriately controlling the respective drive unit.
  • the or each squeegee on the respective squeegee carrier is adjustably guided in the Z direction between a cleaning position and a spacing position, with a squeegee adjusting device being included for adjusting a respective squeegee between the cleaning position and the spacing position.
  • a squeegee adjusting device being included for adjusting a respective squeegee between the cleaning position and the spacing position.
  • the squeegee is moved into the spaced position, it is spaced from the print head in the Z direction or further spaced from the cleaning position.
  • the squeegee adjusted in the distance position does not wipe along the respective associated print head during a displacement movement of the squeegee carrier, or is further away from the print head in a sucking or blowing configuration.
  • the control of the respective squeegee positioning devices takes place in particular on the basis of signals which indicate contamination or a malfunction separately for each print head. Such a signal is generated, for example, in the control units of the corresponding print head modules, which are set up to monitor the functionality of the respective print heads based on measured parameters, for example in the ink supply line. Alternatively, the printheads to be cleaned are determined by monitoring the print image.
  • the or each doctor blade is expediently in the cleaning position along a first guideway, which preferably extends in the X direction, and in the spaced position along a second guideway, preferably extending in the X-direction, whereby the first guideway and the second guideway are connected to one another via a connecting section, particularly extending in the Z-direction, and the respective squeegee setting device is used to switchably fix the taken track is formed.
  • This mechanical design allows the squeegee carrier to be displaced, in particular in the X direction, with each squeegee moving either in the cleaning position along the first guide track or in the spacing position along the second guide track.
  • the or each squeegee is preferably guided in the first guide track and in the second guide track by means of an engagement element.
  • the squeegee adjusting device expediently comprises a magnetic element acting on the respective engagement element in the connecting section. Contactless switching of the respective squeegee between the guideways takes place via the magnetic element. In other words, it is not necessary to mechanically couple the squeegee carrier, which can be moved in particular in the X direction, to the squeegee positioning device in order to enable switching between the first and the second guide track.
  • the single-pass inkjet printer also includes a maintenance area offset in the X-direction to the storage area, in which the print head modules can be placed in a respective maintenance position essentially in the Z-direction and reversibly inserted and stored along the Z-direction.
  • a bearing for the print head modules that is accommodated that corresponds to the printing position is also created in the maintenance area. In this way, a simple change of print head modules from the storage position to the maintenance position and vice versa is possible.
  • print head modules are included in the maintenance area that, for example, have to be subjected to external maintenance or that are to be replaced in the single-pass inkjet printer, since, for example a printhead module is required for printing with an ink that is different in color or texture.
  • a storage device that can be displaced in the X direction is provided in the storage area for the or each print head module, in which a set print head module assumes its storage position, the protective cover being part of the storage device.
  • the storage area and the maintenance area can expediently be coupled in such a way that the or each storage device can be moved in the X-direction with the print head module set from the storage area to the maintenance area.
  • a print head module set in its storage position on the storage device of the storage area can be displaced together with its bearing in the transverse direction (X-direction) from the storage area to the maintenance area and vice versa.
  • a lifting/lowering device acting in the Z-direction is not required to change a print head module from its storage position to the maintenance position.
  • the replacement of print head modules is simplified in the storage area.
  • Printhead modules intended for replacement or maintenance are moved between the maintenance area and the storage area with the appropriate bearing. Since the storage of the print head modules in the storage device in turn corresponds to the storage in the printing area, it is particularly possible to externally adjust the print head modules provided for installation in the single-pass inkjet printer in advance to a reference position.
  • the displaceable storage device preferably comprises the open bearings already described above, into which corresponding bearing pieces arranged on the print head module sink in a self-aligning alignment when lifted. More preferably, catch means are designed for self-adjustment on the displaceable storage device, which, in conjunction with catch means on the print head module, pre-orient a suspended print head module oriented by gravity with regard to the desired print position or storage position and in this case the maintenance position.
  • the means of capture are as already described expediently designed with a safety wedge, which is received by a corresponding wedge shaft.
  • the storage area and the maintenance area each have guide elements for guiding the or each storage device, wherein the guide elements of the storage area and the guide elements of the maintenance area can be coupled to one another to form a continuous displacement path in the X direction.
  • the printhead module intended for replacement or maintenance is moved along the guide elements in a continuous displacement path from the storage area to the maintenance area and vice versa, with the entrainment of the stored storage device.
  • the storage device as such can be displaced along the displacement track via the coupled guide elements between the storage area and the maintenance area.
  • the maintenance area is expediently designed as a mobile maintenance vehicle. If a print head module is to be exchanged, removed from the single-pass inkjet printer for maintenance or fed to the storage area, the maintenance carriage is guided laterally to the storage area and, in particular, is mechanically coupled to it. The print head module is then exchanged by moving the storage device that supports the print head module.
  • the maintenance area comprises a stop buffer and/or a locking element for one or each retracted storage device.
  • the mechanical displacement of a set print head module in its mounting is prevented by the stop buffer, which could possibly be an undesired consequence of replacing it too quickly.
  • a retracted storage device is fixed in the maintenance area by the locking element, so that the print head module can be safely moved to another location, in particular by means of a mobile maintenance trolley.
  • a sensor arrangement is advantageously also included in the maintenance area, which detects the presence a set print head module and/or a retracted storage device is sensed or detected.

  • the weight of components of the print head module 6 acting on the print heads 14 is reduced.
  • a weight-related deformation of the crossbar 12 and thus an undesired displacement of the print heads 14 with respect to the adjusted printing position are prevented. This allows the dimension of the printhead module 6 along the X-direction to be increased over the prior art.
  • the crossbar 12 of the in 1 illustrated single-pass inkjet printer 1 has a length of more than 2.5 m, for example, in the X-direction.
