Definitions

  • the invention relates to a printhead module for a single-pass inkjet printer, which includes a housing component with a crossbar, on which a number of printheads are arranged, the position of which is adjusted to at least one reference position.
  • the invention further relates to a single-pass ink jet printer with such a print head module.
  • a single-pass inkjet printer While in a conventional inkjet printer the printheads mounted on a carriage spray ink droplets in the transverse direction line by line onto the medium transported discontinuously in the running direction, in a single-pass inkjet printer the printheads in printhead modules of the type mentioned at the outset are mounted in the transverse direction over the entire width of the print medium. The print medium is continuously moved in the running direction. While 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. For color printing, several 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 ink jet printer is therefore particularly suitable for industrial applications in the furniture or ceramics industry, where floor coverings such as laminates or ceramic tiles, worktops, moldings or the like are to be decorated.
  • floor coverings such as laminates or ceramic tiles, worktops, moldings or the like are to be decorated.
  • 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 printhead module for a single-pass inkjet printer achieves dimensions of more than 1 m in the transverse direction and in the height, with a tendency to even larger print widths and thus to a further increase in dimensions prevailing.
  • the individual print heads combined in the crossbar of the print head module reach widths of up to several 10 cm. Resolutions of up to 600 x 600 dpi (dots per inch) and more are achieved.
  • Each print head contains several thousand nozzles. Accordingly, a plurality of print heads are arranged in the print head module, which in turn contain a large number of print nozzles.
  • the transverse bracket of the print head module extends 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 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. It can be seen that in a single-pass inkjet printer with several print head modules arranged one behind the other in the direction of travel of the medium, an adjustment of the print heads in the micrometer range is necessary in order to achieve a qualitative produce a high-quality print.
  • the adjustment of a print head module in a single-pass inkjet printer is therefore complex. For example, the position of the print heads must be recorded under a light microscope and set manually, which is a laborious process.
  • the construction of a single-pass inkjet printer is relatively lengthy. An adjustment must also be carried out after each replacement of a print head module. This leads to an unnecessary increase in downtime.
  • a print head module of the type mentioned is known.
  • This printhead module has a hanger portion on its housing for gravity-aligned suspension.
  • the print heads arranged on the housing are adjusted to at least one reference position.
  • the hanging attachment of the print head module which is possible via the hanging part, allows easier installation and removal in the vertical direction.
  • the hanging arrangement of the print head module enables self-alignment due to the force of gravity acting on the center of gravity. When inserting the hanging print head module, this already gives a rough positioning to a later device-fixed print position.
  • the hanging attachment allows self-adjustment of the print head module in the device-fixed printing position, for which open bearing elements are provided, for example, on the single-pass inkjet printer, sinking into the bearing pieces of the print head module when lifting with exact alignment.
  • a manual readjustment is not necessary.
  • the print heads which are adjusted in position relative to a reference position, also achieve an exact alignment of the print heads with respect to the single-pass ink jet printer.
  • a single-pass inkjet printer in which a frame construction, referred to as a head retaining member and carrying a plurality of print head modules, is pivotably mounted about the axis of a paper transport drum (drum).
  • the frame structure can be pivoted from a printing position in which the frame structure is arranged over the paper transport drum into an inclined position. Starting from this inclined position, the frame construction then moved away from the paper transport drum in a horizontal direction by means of two pull-out shafts.
  • the object of the invention is to achieve a further increase in the dimensions of the print head module and thus the achievable print width of a single-pass inkjet printer, without reducing the positioning accuracy of the print heads.
  • a print head module for a single-pass inkjet printer in that a housing component with a crossbar extending in the X direction, on which a number of print heads are arranged, which are position-adjusted to at least one reference position, and a support frame with support means for supporting the support frame, the housing component being mounted on the support frame so as to swing about a pendulum axis.
  • a single-pass inkjet printer which comprises a frame construction and at least one print head module of the aforementioned type, the support frame of the print head module being placed on at least one support arranged on the frame construction by means of the support means.
  • the invention is based on the assumption that when a print head module known from the prior art is enlarged, undesirable changes in the position of the print heads occur due to the increasing intrinsic weight.
  • the housing of the print head module changes its shape under a weight load. If the print head module is dimensioned to be wider than 1 m in the transverse or X-direction, the exact positioning of the print heads is difficult due to the given deformation.
  • the invention is based on the consideration of reducing the weight load on the housing component carrying the print heads, in order to reduce the material stress caused by its own weight.
  • Material reinforcement in the print head module to improve its dimensional stability would undesirably lead to a further increase in weight, which would increase the structural and material complexity of its storage and would make the handling of the print head module more difficult during assembly and disassembly.
  • the invention provides a support frame which is placed on a support of the single-pass inkjet printer by means of support means.
  • the weight of the support frame is borne by the pedestal of the single-pass inkjet printer.
  • the housing component carrying the print heads as such is mounted in an oscillating manner on the support frame. This further provides for easy self-alignment by gravity when lifted into the single pass ink jet printer.
  • the support frame offers the possibility of accommodating heavy components of the printhead module, such as the control boards of the printheads or supply lines for operating resources, lines for electrical energy, control lines for information signals, lines or pipes for air or electrical fuses, etc.
  • the housing component is relieved of weight.
  • the support frame also offers the possibility of dissipating weight structurally at predetermined positions, and thereby defining the load on the housing component carrying the print heads.
  • the invention provides for the print head module to be divided into a supporting frame that can be laid down and a swinging housing component that carries the print heads.
  • the invention thus offers the advantage of further increasing the dimension of the print head module, particularly in the transverse or X direction, in order to achieve larger print widths, while retaining the possibility of simple and precise adjustment of the print heads.
  • a portion of the weight of the printhead module is dissipated via the support frame into the bed of the single-pass inkjet printer. Any material deformation of the housing component carrying the print heads due to its own weight is reduced to a minimum.
  • the print head module in particular the transverse bracket carrying the print heads, preferably extends over the entire print width or over the entire width of the print medium.
  • printing widths and thus transverse dimensions of the print head module or the transverse bracket of more than 2 m are achieved.
  • the print heads can still be precisely positioned in the micrometer range.
  • the pendulum axis is located in the Z-direction above the crossbar of the housing component that accommodates the printheads.
  • the crossbar “hangs” on the support frame, so that when the print head module is lifted vertically, it is positioned under the pendulum axis by gravity and can be pivoted by an inclination or polar angle relative to the support frame.
  • inclined device-fixed printing positions can also be achieved in a simple manner by self-adjustment when lifting, which are necessary, for example, in the case of a technically desired curved course of the printing medium.
  • the pendulum axis is also advantageously aligned parallel to the X-direction, ie in a transverse direction perpendicular to the running direction of the print medium.
  • the pendulum axis thus runs parallel to the main direction of the crossbar. Swinging the crossbar around the swing axis does not then lead to a change in the azimuth angle.
  • An azimuthal rotation of the print head module or the crossbar is given, for example, by a corresponding displacement of the support frame in the support.
  • a small amount of play is preferably provided in the bearing of the pendulum axle, in order to avoid a small azimuthal torsion to allow the housing component or the crossbar relative to the support frame.
  • the support means of the support frame are arranged in the Z-direction above the pendulum axis.
  • the support frame and thus the housing component swinging on it "hangs" on the support means.
  • the printhead module placed on the pedestal of the single-pass inkjet printer, swings downwards in a gravity-oriented orientation.
  • the center of mass of the print head module is expediently arranged below the support means of the support frame with respect to the Z-direction. In particular, this may need to be taken into account if additional modules are placed on the support frame.
  • the support frame preferably comprises two support arms spaced apart from one another in the X direction, with the support means being arranged in the area of the free ends of the support arms.
  • Support arms offer the possibility of structurally shifting the support point of the support frame.
  • the support arms are each extended laterally in the X-direction beyond the crossbar.
  • the support on the single-pass inkjet printer can be structurally spaced from the housing component, which in turn is advantageous for a desired self-adjustment of the print head module and in particular the housing component when lifting into corresponding bearing means of the single-pass inkjet printer.
  • the support frame expediently comprises a cross member which extends in the X direction and is arranged above the pendulum axle in the Z direction.
  • the mechanical stability of the print head module is increased by such a cross member. If necessary, additional modules are placed on the crossbeam.
  • the weight-bearing components of the printhead module are mounted directly on the crossbeam or indirectly via a corresponding frame construction.
  • Mounting aids are also advantageously arranged in the Z-direction above the center of mass of the print head module for lifting in and out in the vertical direction, which is freely oriented by gravity.
  • the print head module is automatically aligned essentially according to the device-fixed printing position to be achieved by means of gravity.
  • the corresponding bearing means of the single-pass inkjet printer make a fine adjustment in terms of a deviation from the gravity-oriented alignment of the print head module, such as a tilt or an azimuthal rotation, but also an offset in the X or Y direction, since the print head module is lifted so that it can move freely.
  • the assembly aids are designed as cable fastening means, with the assembly and disassembly of the print head module being accomplished in the vertical direction by means of a cable lifting system.
  • a coupling module is placed on the support frame in the Z direction, which includes a first coupling part with a plurality of first connections at least for the supply of operating resources and for the provision of electrical energy, the support frame having a second coupling part with a plurality of second connections which are complementary to the first connections, and wherein the first coupling part and the second coupling part can be mechanically coupled and uncoupled with one another to establish a connection between the first connections and the second connections.
  • the coupling module is coupled to the printhead module via a multi-coupling, which both connects various connections for operating resources, electricity, control signals, etc. in the case of a coupling, and also creates a mechanical connection.
  • the mechanical connection of the coupling parts is established via a screw connection.
  • the first and second connections are also coupled.
  • decoupling takes place by loosening the screw connection, with the complementary connections moving away from one another.
  • the screw connection is particularly preferred designed to be motorized. Securing means are preferably included which prevent unintentional opening of the coupled parts.
  • a coupling module which is connected mechanically and in terms of connection technology to the print head module or its support frame by means of a multi-coupling, offers several advantages. For example, this allows for a simplified connection of the print head module to the control and supply lines. The control and the supply of the large number of print heads are thus carried out via a single central module. On the other hand, the load from the supplied control and supply lines is also dissipated via the support frame without loading the housing component that supports the print heads.
  • the coupling module is particularly preferably supplemented by reservoirs, such as ink tanks. Their weight also has no effect on the housing component carrying the print heads.
  • the coupling module allows easy decoupling and coupling of the print head module via the multi-coupling, which makes sense with regard to repair and maintenance work.
  • the coupling module is removed, the print head module is easier to access.
  • the print head module is thus easier to maintain and repair. In addition, it can be installed and removed more easily.
  • the coupling module is expediently placed on the cross member of the support frame.
  • the assembly aids are advantageously arranged on the clutch module.
  • the weight of the coupling module is absorbed directly by the support frame via the cross member.
  • the printhead module can be lifted in and out of the single-pass inkjet printer via the coupling module.
  • the print head module can be easily picked up and removed via the multi-coupling.
  • the housing component comprises two side walls which extend in the Z direction and which are connected to the transverse bracket, with the support frame being arranged between the side walls.
  • the housing component a bow or U-shape overall, with the limbs being formed by the side walls are.
  • the pendulum axis is defined in particular by a respective pivot bearing at the free ends of the side walls, with the pendulum axis piercing through the side walls at the pivot bearing.
  • the or each pivot bearing is designed as a radial plain bearing.
  • a radial slide bearing allows the crossbar of the oscillating housing component carrying the print heads to be offset relative to the supporting frame along the oscillating axis. This facilitates fine positioning of the printhead module during assembly.
  • the or each radial slide bearing is formed by a guide pin that extends in the X direction and is guided through an oversized opening.
  • additional degrees of freedom in the X and Y directions are granted to the crossbar of the housing component that carries the print heads relative to the support frame. If the freedom of movement is to be additionally restricted in one of the two directions for reasons of clearly defining the spatial position of the housing component, this is done by a corresponding reduction in the play between the opening and the guide pin.
  • an opening is preferably designed as an elongated hole, with the freedom from play being restricted, for example in the Y direction.
  • one opening is designed as an elongated hole aligned in the Z direction and the other opening is designed as an oversized round bore, an azimuthal rotation of the housing component relative to the support frame is possible, although the pivot point is fixed by one plain bearing with an elongated hole is.
  • the guide pin of the or each radial slide bearing is expediently mounted on the support frame, which is guided in an opening on the housing component, in particular in a side cheek.
  • the guide pin is designed as a guide screw.
  • a side wall is mounted on both sides on the crossbar and on the side walls of the housing component.
  • the housing component is mechanically stabilized via the side wall. Internal components contained in the housing component can also be supported against the side wall, whereas in an open design a displacement of such components can lead to undesired twisting of the crossbar carrying the print heads.
  • the support means of the support frame each comprise a planar support surface extending in the X-Y plane. With a fixed Z position, such a support surface enables the support frame and thus the print head module to be positioned variably in the X-Y plane.
  • the storage position of the support frame in the X-Y plane results from the automatic fine adjustment when lowering the print head module using the counter bearings or catches provided on the single-pass inkjet printer.
  • At least one support bearing is additionally included to support the support frame on the housing component in the Y direction.
  • a proportion of the weight of the support frame is transferred to the housing component via such a support bearing as required.
  • the support bearing is designed in particular in such a way that in the event of an offset in the Z direction when the print head module is lifted, it increases the freedom of movement in the Y direction, and thus in the lifted position of the print head module the pendulum movement or an inclination of the housing component relative to the support frame by the polar angle allows.
  • the support bearing is then preferably designed in such a way that it limits the degrees of freedom in the Z direction and in the Y direction.
  • a ball pivot bearing is provided as a support bearing.
  • Two support bearings are preferably provided, which are spaced apart from one another in the X-direction.
  • a fixed-loose bearing or a loose-loose bearing is expediently used as a bearing combination with respect to the X-direction.
  • one of the support bearings is preferably designed as a fixed bearing and the other of the support bearings is designed as a fixed bearing.
  • the fixed bearing is preferably a ball pivot bearing with a conical or ball socket formed.
  • the floating bearing is advantageously designed as a prismatic thrust bearing, in particular also as a ball pivot bearing.
  • a prismatic pan running in the X-direction is provided. Such an embodiment makes it possible to absorb a longitudinal offset of the crossbar support in the X-direction, for example as a result of thermal cycling. *
  • At least two bearing pieces spaced apart in the X-direction are arranged on the housing component of the print head module, which are each designed for self-adjusting positioning in an open bearing.
  • the bearings which are self-adjusting in particular in the vertical direction, are not complicated in design, in particular when, more preferably, catch means are arranged on the housing component for rough positioning in relation to the bearing seat of the bearing pieces. It is only necessary that the two bearing elements realizing the bearing automatically find each other during the gradual insertion of the print head module in particular in a gravity-oriented vertical alignment, which ultimately determines the final printing position.
  • Suitable bearing pieces are designed to cooperate with, for example, a pan, blade or tip bearing. In this respect, the bearing pieces are in particular conical, tapered, edged, pointed or spherical.
  • the bearing pieces are mounted on the housing component in a height-adjustable manner. In this way, production-related dimensional tolerances can be compensated for or the print heads can be adjusted in height or in the Z-direction to the printing position.
  • one of the bearing pieces is designed for positioning in a fixed bearing and the other of the bearing pieces is designed for positioning in a floating bearing in the X direction or transverse direction.
  • An expansion of the print head module in the transverse direction is in turn intercepted via the movable bearing.
  • the fixed bearing is in each case designed as a ball pivot bearing and the floating bearing is given by a prismatic thrust guide in the transverse direction.
  • the bearing pieces are preferably in the form of ball pivots educated.
  • the fixed bearing is then advantageously equipped with a punctiform rotary bearing with a conical socket, in which the spherical end of the pin is received and positioned when the print head module is inserted vertically.
  • the prismatic thrust guide is also designed as a ball-and-socket bearing, although the socket is designed with a prismatic cross-section along the transverse direction.
  • the prism slide guide then fixes the parallel position of the print head module to the cross direction. In the transverse direction itself, there is still a linear offset as a degree of freedom.
  • a stop piece for striking a stop surface is arranged on the print head module.
  • a stop piece aligns the inclination of the print head module around the polar angle when the print head module is lifted in vertically.
  • the stop piece particularly advantageously comprises a ball pivot extending in the transverse direction or in the X-direction.
  • the ball pivot gradually comes into contact with a device-fixed stop surface, which finally positions the ball pivot in the Y direction or the running direction of the print medium.
  • a ball pivot together with a convex stop surface, for example, allows a defined stop regardless of the vertical height.
  • the respective print head module is then precisely fixed, for example, by the two open bearings, namely a ball pivot bearing as a fixed bearing and a prismatic slide guide as a floating bearing, as well as by the stop piece leaning against the stop surface.
  • the inclination or polar angle is determined by the abutted stop piece.
  • the corresponding guidance is taken over by the stop piece in interaction with the device-fixed vertical stop surface.
  • each print head module By determining the position of the print heads in relation to at least one reference position, they are always aligned identically when the print head module reaches the print position, except for unavoidable dimensional tolerances. In other words, each print head module always has the same positional alignment of its respective print heads with respect to at least one reference position. This will create a easy replacement of the print head module achieved.
  • the position of the printheads of the replaced and a newly inserted printhead module are identical with regard to the device side.
  • the printheads For the purpose of adjusting the position of the printheads, they are mounted in the printhead module such that they can be displaced in the X and Y directions, for example.
  • the print head module In order to adjust the position, the print head module is brought into a mounting position comparable to the subsequent printing position before it is delivered using a suitable tool.
  • the individual print heads are then adjusted to a reference position, for example under the light microscope in the micrometer range.
  • the print heads are preferably positioned in relation to the bearing pieces, for example the ball pivots.
  • the print head modules are inserted into the corresponding workpiece according to the later printing position before delivery.
  • This tool has the identical bearings as the later single-pass inkjet printer.
  • the print heads are parallelized and aligned in the X and Y directions.
  • the single-pass ink jet printer that accommodates the print head module preferably has a support for counter-supporting the support frame, which includes a flat support surface that is supported via a ball joint.
  • a ball joint With an in particular freely movable ball joint, the bearing surface of the support is automatically aligned parallel to the bearing surface of the bearing means of the support frame when the print head module is set down. Consequently, this automatically results in a stable, because flat, placement of the print head module on the single-pass inkjet printer.
  • the orientation of the ball and socket joint results in a flat support, in particular when the print head module has an angle of inclination in the printing position with a print medium guided in an arc.
  • the at least two bearing pieces of the housing component of the at least one print head module which are spaced apart in the X direction, are preferably—if provided—positioned in each case in an open bearing arranged on the frame construction of the single-pass inkjet printer.
  • the stop piece of the housing component of the at least one print head module expediently rests against a stop surface arranged on the frame construction of the single-pass inkjet printer. As described above, this results in an exact and reproducible alignment of the print head module.
