Definitions

  • the invention relates to a method and an apparatus for printing plate-shaped workpieces according to the preambles of claims 1 and 9. Accordingly, the workpieces are printed in a printing nip, which is formed by two spaced-apart adjustable pressure rollers.
  • the plate-shaped workpieces are transported for this purpose by means of a transport device to the printing nip.
  • the pressure rollers forming the printing nip can be printing cylinders for direct printing, application rollers for indirect printing and impression cylinders.
  • Such printing methods and corresponding devices have been known for a long time. Recently, by means of such a printing process, increasingly printed images of decors and grains are also applied to wood-based panels in order to give them an appearance of real wood. This is not only more cost effective compared to a real wood veneer, but also compared with the film coating of wood-based panels that has been in use for a long time.
  • the print image is indispensable for the print image to be positioned on the workpiece within very close tolerances, typically with tolerances of about ⁇ 0.1 mm to ⁇ 0.25 mm. Only in this way is it possible to achieve an optical quality of the printed surface that is comparable to conventional film coating.
  • the printing gap forming pressure rollers are adjustable in their distance from each other to print plate-shaped workpieces of different thickness can. Again, completely different conditions are present, such as the printing of paper sheets and paper webs or films.
  • the mutual adjustment of the pressure rollers is difficult to create in the required parallelism, which ensures the desired accuracy in printing even with large workpieces and correspondingly long pressure rollers.
  • a height restriction of the pressure rollers, ie a non-parallelism in the plane spanned by the pressure roller axes level results in pressure by the flexibility of rolling on the workpiece surface pressure roller over the width not constant remaining effective radius.
  • a machine and a method for printing boards, plates or the like is known in which a forme cylinder with the printing forme and an impression cylinder forming part of a guide bed form a printing nip.
  • the pressure gap can be set to workpieces of different thickness.
  • a printing machine is known in which an upper and a lower pressure roller form a pressure gap, wherein the two pressure rollers are each mounted in a support structure and wherein these two support structures are pivotable about a parallel to the axes of the pressure rollers extending, spaced therefrom pivot axis against each other.
  • the printing gap can be increased or decreased depending on the angular position of the support structures.
  • the pivoting of the support structures about an axis parallel to the pressure roller axes ensures that the parallelism of the pressure rollers is maintained when adjusting the pressure gap.
  • the FR-A-676977 discloses a printing machine in which two pressure rollers form a printing nip, and this printing nip can be increased and decreased by moving the two pressure rollers parallel to each other or away from each other.
  • the parallelism of the pressure rollers is normally readjusted by hand.
  • a sheet of paper is introduced into the nip, optionally with a plate therein, and reciprocated in the nip.
  • An experienced printer can then use the hand-held sheet of paper to sense whether or not the nip is parallel across its entire width. This tactile measurement and fine-tuning provides useful results in tenths to hundredths of a millimeter range.
  • the present invention is therefore based on the object to propose a method and an apparatus of the type mentioned, which allow to print plate-shaped workpieces with improved print image tolerances.
  • the invention proposes to measure before the nip, the thickness of each workpiece, optionally - if present - together with the conveyor belt and its tolerant thickness, and the pressure nip forming pressure rollers by means of actuators at their bearings automatically to the measured thickness of the workpiece - if necessary with conveyor - set.
  • the press nip is accordingly adjusted to this wedge shape by interleaving the two pressure rollers relative to one another, ie by obliquely changing the distance between the two pressure rollers, so that the effective radius of the pressure roller overlaps the entire width of the workpiece remains constant and so the desired minimum image tolerance values can be achieved.
  • the invention can be implemented with a mutually independent, mutually independent, motorized pressure gap adjustment provided as a function of a workpiece thickness signal previously measured in line.
  • the thickness measurement can take place in the transport direction over the entire workpiece length, so that a thickness profile is measured, by means of which the printing gap can then be adjusted in real time as the workpiece passes.
  • This measure allows regardless of a change in thickness of the workpiece over the width of an adjustment of the pressure nip at changes in thickness of the workpiece over its length.
  • such can also be used to correct the correlation between the thickness measured before the pressure and the adjustment of the pressure gap.
  • the measured difference of the bearing forces can generate a correction element.
  • the conditions in printing presses of the present type are complex, and an adjustment of the printing gap in real time in response to corresponding measured values generates a vibratory system, so that it is advantageous may be to average the bearing forces and their difference in time intervals and then perform a trend correction calculated by a suitable algorithm.
  • a measured bearing force difference then does not directly affect the workpiece just measured, but tends to result in better and better results across several workpieces.
  • the present invention for measuring the workpiece thickness before reaching the nip sensor sensor advantageously also the leading edge of the workpiece can be detected and accelerated or delayed with this information, the workpiece and / or a pressure roller involved in printing to ensure a positionally correct image beginning on the workpiece ,
  • This method is inherently out of the DE 103.33 626 A1 known.
  • the two pressure rollers of the printing nip can be interlocked to a small extent as offset adjustment, so that a transversely directed to the transport direction of the workpiece force acts on this.
  • This may be desirable in order to guide the workpiece reliably along an edge boundary, for example of a side ruler, and thus to ensure a precise pass through all printing gaps of a multicolor printing press in the case of rectangular plates.
  • the present invention thickness measuring device in front of the printing nip can be designed so that above and below the workpiece Distance sensors are arranged and the difference of the thickness of the workpiece is determined.
  • the thickness measuring device may also consist of two imaging sensors which laterally scan the two side edges of the workpiece and accordingly record a profile thereof.
  • the thickness gauge may consist of a measuring calender provided with displacement sensors for determining the thickness of the workpiece.
  • the great advantage of a measuring calender is that the values measured by it correspond exactly to those values which have to be set at the printing nip, even if the workpiece does not have an exact wedge shape, but a certain waviness, which can only be averaged out by the correction of the pressure nip because the pressure rollers are cylindrically shaped.
  • not to be underestimated advantage of a Meßkalander offers the ability to not only displacement sensors, but also to attach force sensors to its bearings in order to carry out the above-described force measurement or force difference measurement before the workpiece reaches the nip. This opens up the possibility of adjusting the pressure gap before the pressure by means of a force difference measurement.
  • the present invention is particularly suitable for multi-color printing, so that preferably a plurality of pressure gaps are arranged in line one behind the other.
  • a very high accuracy results when printing on the different colors, while the workpiece-dependent correction requirement can be carried out by a single thickness measurement before reaching the first printing nip.
  • the force measurement at the bearings of the individual pressure rollers is specific for each pressure nip.
  • FIG. 1 is schematically illustrated in plan view an embodiment of an inventive device. It is a printing machine for a simple direct printing or a first printing station for a multi-color printing machine, the other printing stations are not shown for simplicity.
  • a conveyor belt 1 passes through a pressure nip 2, which is formed by a pressure roller formed as a gravure cylinder 3 and a non-visible in plan view, arranged below the conveyor belt 1 impression cylinder.
  • the gravure cylinder 3 is height adjustable, wherein the two servomotors 4 and 5 can be operated independently.
  • a plate-shaped workpiece 7 is brought in a symbolized by the arrow 8 passage direction to the pressure nip 2, where it is transferred to the conveyor belt 1.
  • a thickness measuring device 9 which is formed here from each of two above and below the workpiece 7 arranged right and left distance sensors 10. Accordingly, the workpiece 7 is measured both on its right and on its left side to detect differences in thickness, for example by a slight wedge shape. If such differences in thickness are present, the left positioning motor 4 and the right positioning motor 5 are correspondingly adjusted differently, so that the gravure cylinder 3 is slightly entangled against the impression cylinder in order to reproduce the wedge shape of the workpiece 7. Accordingly, the effective radius of the gravure cylinder 3 is then constant over the entire width of the workpiece 7 during printing, so that no image distortions occur. A lateral deflection of the workpiece 7 is then not to be feared in the nip 2.
  • left and right servomotors 4, 5 are also provided with force measuring sensors to measure the forces acting on the gravure cylinder when printing the workpiece 7 bearing forces directly or indirectly.
  • a difference of the left and right bearing forces means that the setting of gravure cylinder 3 and counter-pressure cylinder due to an offset or other effects, the thickness profile of the workpiece 7 does not exactly over the width and therefore undesirably a difference in the effective radius of the engraving cylinder 3 from the left to the right side of the workpiece 7 in spite of the adjusted due to the thickness gauge 9 servo motors 4 and 5 occurs. This can then be used for the tendency correction of the relationship between the values recorded in the thickness measuring device 9 and the adjustment of the servomotors 4 and 5 for the following workpieces 7.
  • FIG. 2 A diagram of the forces measured by the two force measuring sensors assigned to the servomotors 4 and 5 is shown FIG. 2 , Above, the bearing force is recorded left and bottom, the bearing force right over time, which - well recognizable due to the approximate rectangular shape of the forces occurring that a workpiece 7 has been transported through the nip 2 in the time.
  • the bearing force on the left was significantly higher than the bearing force on the right, which suggests that on average the thickness profile of the workpiece 7 does not harmonize with the setting of the engraving cylinder 3 and the counterpressure roller.
  • the higher left bearing force indicates that there the effective radius of the engraving cylinder 3 is lower than on the right side.
  • the force measuring sensors record the time course of the left and right bearing forces, as well as with the thickness gauge 9, not only the thickness difference of the workpiece 7 between the right and left sides are measured, but also its thickness profile in the direction of passage.
  • FIG. 3 and FIG. 4 show two different embodiments of a thickness measuring device 9 of the device according to the invention.
  • a total of four distance sensors 10 are provided for thickness measurement, seen above the workpiece in the direction of passage 8 on the left side 10a and on the right side 10b and below the workpiece on the left side 10c and on the right side 10d.
  • the thickness of the workpiece 7 is measured on the right and left.
  • a leading edge sensor 11 is detected, which sends a signal as soon as the leading edge 7 of the workpiece passes it. With the help of this signal can then - as is well known - the printed image are triggered or optionally the gravure cylinder 3 or arranged between the gravure cylinder and the workpiece 7 blanket cylinder so accelerated or decelerated that the print image start coincides with the front edge of the workpiece 7 and no Edge remains.
  • FIG. 4 another principle of a thickness measurement is shown: seen in the direction of passage 8, the side of the workpiece, two CCD cameras 12 are arranged, with a left CCD camera 12a scans the left side edge of the workpiece 7, while a right CCD camera 12b the right Side edge of the workpiece 7 monitored. Based on the pixels recorded by the CCD cameras 12 and their gray values, the respective thickness of the workpiece 7 guided past the CCD cameras 12 can be determined.
