Definitions

  • the invention relates to a device for finishing a surface, preferably the narrow surface, of a workpiece, which preferably consists at least partially of wood, wood-based materials or the like, with a pressure unit.
  • Known devices for decorating or refining the narrow surfaces or other surfaces of workpieces made of wood, wood-based materials or the like, by means of digital printing have several print heads that are arranged linearly next to each other and are firmly connected to a printing unit.
  • a device for printing on surfaces with multiple movable printheads according to the preamble of claim 1 is made of DE 10 2012 005 087 A1 known.
  • a device for inkjet printing on a complex surface is made of FR 3 087 705 A1
  • a device for producing components with a predetermined surface appearance, in particular front panels of kitchen units, is known.
  • US 2004/0028830 A1 A method and a device for manufacturing a component with a surface of predetermined appearance are known.
  • EP 2 292 437 A1 known.
  • the invention is based on the objective of providing a device for finishing a surface, preferably a narrow surface, of a workpiece, which makes it possible to finish surfaces or narrow surfaces of such workpieces, in particular to print on them, which have non-linear workpiece contours such as radii, kinks or the like.
  • the device for finishing a surface, in particular a narrow surface, of a workpiece which preferably consists at least partially of wood, wood-based materials, or the like, comprises a printing unit.
  • the printing unit and the workpiece can be moved translationally relative to each other.
  • the printing unit has one or more printing heads.
  • Each printing head is rotatable about a vertical axis of the respective printing head and relative to the printing unit by means of a pivoting element, and/or the one or more printing heads are, together with the printing unit, pivotable about a common axis, preferably equidistant from each printing head.
  • the vertical axis is pivotable.
  • a translational relative movement between the printing unit and the workpiece and a rotational movement of at least one print head are performed simultaneously.
  • Such a device allows the printhead with the printing unit and the surface of the workpiece to be finished to be moved past each other, and at least one printhead can simultaneously be aligned by rotation so that a print media outlet of the printhead is always at a desired angle to the surface to be finished.
  • the printhead is aligned with the workpiece, largely independent of the contour of the surface to be finished. This alignment of the printhead or the print media outlet with the surface to be finished allows the surface to be finished with the desired quality, for example, printed with a desired design, without unwanted distortions.
  • a device that allows multiple printheads to be individually swiveled relative to the printing unit enables the finishing of even narrow surfaces in a single pass using multiple printheads. This allows the surface to be printed directly with multiple media, such as several colors, even if the printing unit only passes over the surface once. In other words, only a single pass is required to completely finish the surface. Furthermore, it is advantageous that only one energy unit is needed for at least the partial curing of the various layers, since the layers from the different printheads can be applied in a single pass. Additionally, the individual swiveling of the printheads relative to the printing unit allows for even greater adaptation to the workpiece contour, thereby further increasing the precision and quality of the print.
  • a device in which one or more printheads can be rotated together with the printing unit eliminates the need for separate pivoting elements for each printhead. This reduces costs and maintenance while increasing the device's reliability.
  • the shared rotation around a vertical axis equidistant from each printhead ensures that each printhead rotates through the same angle. This further improves print precision and quality. The increase can be achieved because the individual printheads perform the same movement with the same control signal.
  • the printing unit In the translational relative movement between the printing unit and the workpiece, either the printing unit can be moved along the contour of the workpiece, the workpiece can be guided past the printing unit according to its contour, or the printing unit and workpiece can each move independently.
  • the overall movement of the print head relative to the surface (especially the narrow edge) of the workpiece to be finished comprises the rotational movement of at least one print head and the translational movement of the printing unit or the workpiece.
  • the translational movement of the printing unit or the workpiece need not be purely translational but can also be superimposed with a rotational movement.
  • the described printing unit can print on irregular surfaces, such as surfaces with a cutout, (handle) recess, indentation, or similar feature.
  • irregular surfaces such as surfaces with a cutout, (handle) recess, indentation, or similar feature.
  • the number of active nozzles can be varied during a swiveling motion.
  • the device is further configured such that the printing unit and the workpiece are moved translationally relative to each other in such a way that the printhead always maintains the same distance from the surface (in particular, the narrow edge) of the workpiece to be finished during the translational relative movement.
  • the device is also configured such that, during the translational relative movement between the printing unit and the workpiece, the printhead is moved by a rotation about the vertical axis such that the printhead and/or a print media outlet of the printhead is oriented at a constant angle, preferably orthogonal, to the surface of the workpiece to be finished.
  • an orthogonal alignment or an alignment at a specific angle of the printhead to the surface to be finished means that, in particular, the print media outlet, i.e., the opening of the printhead (print media outlet), through which, for example, an ink jet emerges, is aligned to the surface of the workpiece to be finished in such a way that an imaginary extension of such an ink jet and the surface (especially the narrow surface) intersect at an angle of 90° or the specified angle.
  • the device is further designed such that the translational relative movement between the printing unit and the workpiece and the rotational movement of at least one print head along a contour of the workpiece are carried out, wherein an alignment of the printing unit, print head and workpiece to each other is carried out by manual control, a positive guidance with a touch probe, a control with sensors or on the basis of geometric data of the workpiece.
  • geometry data can be used to calculate the movement of the workpiece, the printing unit or the print heads by means of a control and/or regulation unit and to move the corresponding unit.
  • Manual control of the printing unit increases the flexibility of the device, as, for example, certain areas of the surface to be finished can be finished multiple times or under different conditions such as angle or distance if required.
  • Controlling the printing unit with sensors enables particularly precise finishing results, as the distance and angle of the printhead to the surface being finished can be precisely adjusted to the desired value. Furthermore, with sensor-based control, finishing can be carried out even without knowledge of the workpiece's exact geometry, since the necessary parameters, such as the angle and distance of the printhead from the device, are automatically adjusted for each individual workpiece. After finishing, the same sensors can be used to check the quality of the applied finish, such as the layer thickness. For this purpose, if the sensors are located on the printing unit, they can be moved along the surface of the workpiece being finished once more.
  • the surface of the workpiece to be finished can be precisely finished, even without the need for costly or potentially error-prone sensors.
  • At least one printhead has its own working stroke, by which the printhead can be moved translationally relative to the printing unit. and by which the distance between the print head and the workpiece can be changed.
  • the precision with which the device refines a surface to be finished can be further increased by having its own working stroke for the print head, since the lower inertia of the print head compared to the printing unit allows the distance between the print head and the narrow surface of the workpiece to be set with less fluctuation.
  • the device is further designed such that at least one printhead can be exchanged in the printing unit by means of a tool changing system.
  • the printing unit can be exchanged for other machining tools (milling cutters, drills, etc.) using a tool changing system.
  • This design is particularly suitable for CNC applications.
  • printheads for sealing the surface or applying adhesive can be interchanged in the same printing unit and used for finishing.
  • the device is further designed such that the one printhead or the multiple printheads and the printing unit can be pivoted together about a common horizontal axis.
  • This design allows the device to be used to refine surfaces that are not at least partially orthogonal to a workpiece's support surface. For example, it can be used to refine the surfaces of chamfers on flat workpieces, such as those that form a transition between...
  • the device forms the narrow surface and the flat side of the workpiece.
