Definitions

  • the invention relates to a device and a method for preparing a punching tool according to the preamble of claim 1 and claim 9.
  • Materials in the form of webs or sheets are processed in the manufacture of packaging. In several processing steps, the sheets are printed, embossed, creased, perforated, punched, cut, stapled, glued and folded into packaging, for example.
  • a sheet processing machine can include various processing steps such as printing, cutting, embossing, creasing, punching, perforating, gluing and/or stapling. Such sheet processing machines often also have inspection devices. Sheets are usually processed and trimmed in processing machines with form-bound punching and cutting devices.
  • Such a processing machine is designed, for example, as a punching, cutting, perforating, embossing and/or creasing machine. If such a processing machine is referred to below as a punching and/or punching machine, this also means in particular a cutting, perforating, embossing and/or creasing machine.
  • a punching and/or punching machine this also means in particular a cutting, perforating, embossing and/or creasing machine.
  • flat die-cutting in particular flat-bed die-cutting. In these, several sheets are processed one after the other by means of a cyclically repeating movement.
  • Rotary punching machines can, for example, be equipped with the modules punching unit, creasing unit, embossing unit and stripping unit.
  • Such a rotary punch is, for example, from WO 2017/089420 A2 known.
  • Manufacturing tolerances of tools or different load distribution during processing, especially punching can lead to wear on the knives or tools with height differences. This results, for example, in an unequal punching pressure, which results in an unclean punching result, for example.
  • the punching tools and/or creasing tools and/or embossing tools have to be reworked to compensate for the errors and/or the deviations.
  • an agent is applied to the back of the respective processing tool. This is referred to as preparing the processing tools.
  • the EP 2 327 521 A1 discloses, for example, a method of trimming dies in flatbed die cutters.
  • trimming is usually carried out using special adhesive tape and/or special adhesive strips, which compensate for the unevenness and/or deviations and/or errors on the knives.
  • the errors and/or deviations are compensated for by gluing the punching and/or creasing knives.
  • the punching tool Due to the fairly high tolerances in the flatbed area, the punching tool can be trimmed sufficiently well with the adhesive tape.
  • Such tape is available in different strengths.
  • (trimming) sheets can be used for trimming with the required basic contour.
  • Preparation sheets of paper, such as tissue paper, plastic or the like, are used. Such sheets are usually thin and pressure-resistant and represent the entire required cutting contour.
  • the pamphlet DE 10 2012 017 636 A1 relates to a method for determining the machine-dependent adjustment requirements of a stamping and embossing machine, a tool-specific adjustment requirement being read from a database.
  • a respective tool type is associated with set-up requirement values or a set-up requirement factor.
  • the DE 10 2013 016 755 A1 discloses a device for trimming on flat-bed stamping and/or embossing machines, the trimming being provided by targeted control of heating cartridges in a plurality of metal blocks made of aluminum arranged next to one another in a matrix-like manner.
  • the heating cartridges are controlled by a control unit via a bus system of a machine control.
  • storage devices are also provided which have tool-dependent adjustment requirements and consequently the heating cartridges in the respective metal blocks are actuated in this regard.
  • DE 20 2013 100 883 U1 discloses a master sheet of a strip steel die.
  • the invention is based on the object of creating a device and a method for dressing.
  • the advantages that can be achieved with the invention consist, in particular, in the fact that an operator can be able to prepare more quickly and easily.
  • a makeready sheet behind the processing tool in particular a punching tool.
  • Complex production and/or storage of the overlay sheet which involves costs in addition to the costs of the processing tools, in particular the punching and/or creasing tools, can be dispensed with.
  • a makeready sheet not only has to be produced and/or archived in addition to the tool costs, but also suffers damage over time through repeated use and then has to be produced again, which is costly and time-consuming.
  • the invention is not limited to rotary machining methods, but is also particularly suitable for use in flat and cyclic machining methods.
  • Makeready is also useful in flatbed die-cutting machines, since the use of makeready means means that conventional makeready sheets can be dispensed with there as well. Depending on the use of the dressing, larger deviations can also be compensated.
  • a further advantage that can be achieved with the invention consists in particular in the fact that the time required for preparation is minimized and handling is improved.
  • a digital processing contour is used for this purpose.
  • the digital processing contour of the processing tool can be determined, for example, from a preliminary processing stage, for example a preliminary stamping stage and/or a preliminary printing stage. After inspection of the processing tool and/or the processing result Areas on the digital processing contour are marked. For the inspection, for example, a test sheet is processed or the contours of the processing tool are viewed directly. This is done either by an operator or fully automatically by an integrated inspection device.
  • Marking preferably takes place at a control station, where the processing contour or the cutting layout is displayed and the (dressing) points to be reworked are marked directly by means of an input device.
  • markings in mobile devices are also conceivable and useful.
  • any digital input device can be used.
  • This digital data can then be used in different ways to facilitate and, if necessary, automate the preparation of the processing tool. For example, this data can also be stored and called up again at any time. In particular, when using overlay sheets, the work result cannot/could not be saved and one had to be produced again.
  • Such a simplification occurs, for example, by coupling to a projection device.
  • the processing tool is positioned in an aligned manner and the processing contour with the markings is projected onto the back of the processing tool.
  • An operator recognizes very quickly and easily the points at which a dressing must be applied.
  • the finishing points are thus identified in a simple manner.
  • a short-distance projector which in particular offers space savings, is particularly preferred for this purpose.
  • a liquid trimming agent is used to make operation even easier. This can be cured, for example, by means of radiation, in particular UV radiation.
  • the digital data can be forwarded directly to a controller for controlling an actuator arm.
  • the actuating arm can then, for example, apply the finishing agent fully automatically.
  • the controlled arm can, for example, communicate by means of a machine control and signals for example from a quality control.
  • a quality control is arranged in different areas of the punching machine and/or can also be arranged, for example, on upstream machines, such as printing machines, and/or downstream on folding and/or gluing machines.
  • different processes can be linked with each other and automation can be further advanced. Complex and/or imprecise manual trimming can be dispensed with. Additional labor costs can be saved in this way. For example, an operator would only have to select the UV layer thickness to be applied.
  • the controlled arm does the rest automatically. For example, curing also occurs fully automatically. In this embodiment, for example, the projection could be dispensed with.
  • a further advantage that can be achieved with the invention is, in particular, that the processing tool is trimmed directly in the processing machine.
  • the processing tool is removed from the processing machine semi-automatically and/or fully automatically, for example similar to an automatic plate changer of a printing press, and the dressing is applied fully automatically using the digital data, for example with the actuating arm.
  • a processing tool, in particular a punching plate can then, for example, be automatically spot-painted directly in an automatic plate changing machine and then hardened. Then removing, for example, the punching plate from the shaping unit or the punching tower would be omitted.
  • a fully automatic plate changer an operator does not even have to leave the control station. After hardening, the plate can be drawn in again using the plate changing machine.
  • a further advantage that can be achieved with the invention consists in particular in the fact that trimming takes place by means of a paint and/or paint mixture that can be applied.
  • Spray paints are usually used for flat and/or zoned application. This allows an operator to make makereadies faster and easier will. Precise lines for small areas can be applied using touch-up sticks.
  • Such a paint can preferably be applied and then cured.
  • a waiting time for the paint to dry can be minimized by using a preferably large-area blasting device.
  • a radiation device is preferably attached to a fixed structure, so that incorrect radiation can be avoided and better protection for an operator can be guaranteed. In particular, faster curing and/or drying over the entire surface can be achieved in this way.
  • Such curing is preferably effected by UV light.
  • Such a method has the advantage that the paint can be applied very precisely and that curing can take place in a very controlled manner.
  • a scratch-resistant layer is formed which has sufficient temperature resistance and resistance to mechanical loads for use in a punching machine.
  • thin layers with the required tolerances of 5-10 ⁇ m can be realized.
  • a layer thickness can be adjusted. Layer thicknesses of between 5 and 15 microns can be achieved in this way.
  • the UV lacquers are preferably cured over a large area by means of a UV LED, which is preferably arranged on the dressing device.
  • the finishing done in this way can be removed very easily after it has been hardened and/or dried over a large area.
  • the post-processing and/or dressing can thus be applied more easily and handling of the tools required for this is significantly simplified.
  • the dressing can be applied very precisely and only cutting contours that actually have to be dressed can be reworked. In the case of a large-area zone dressing, zones are already dressed that were already sufficient in terms of cutting quality. This can be avoided.
  • the dressings are scratch-resistant, mechanically resistant and resistant to the temperatures introduced into the die-cutting cylinder (temperature-resistant). Due to the fast curing and/or drying, the operator's waiting time during preparation can be minimized.
  • the finishing agent can be a dispersion consisting of a dispersion medium and a disperse phase.
  • the dispersion medium has at least one, preferably highly volatile, solvent.
  • the disperse phase consists of a finely divided solid. This remains when the solvent evaporates and can be used for trimming. Very thin layers can be applied.
  • the dispersion is particularly easy to apply using an application pen and can be applied automatically with an adjusting arm.
  • the dispersions are characterized by a high proportion of volatile solvents. As a result, a drying time can be kept very short. For example, a drying time of a few seconds can be achieved.
  • Such a dispersion particularly preferably has a ketone, preferably methyl ethyl ketone (MEK for short), as the solvent.
  • MEK methyl ethyl ketone
  • the solvent evaporates very quickly, resulting in rapid drying of the dispersion.
  • the remaining particles and/or pigments of the dispersion form a robust layer which is scratch-resistant, pressure-resistant and heat-resistant.
  • the dispersion preferably has a high proportion of at least 50%, more preferably at least 60%, even more preferably 70% solvent.
  • the layer thickness of the finishing layer can be easily adjusted by adjusting the proportion of the solvent.
  • a dispersion which has finely divided particles, in particular pigments, is particularly advantageously used.
  • the dispersion for finishing is preferably an ink, more preferably an inkjet ink.
  • Ink has the advantage that it is available at low cost and with high availability. In addition, inkjet ink poses few hazards to an operator. Radiation for drying can also be dispensed with. Particularly preferably, the ink can also be applied in an automated manner using an inkjet printing device.
  • a further advantage that can be achieved with the invention consists in particular in the fact that the processing tools, preferably punching tools, can be inspected using a mobile device and detected errors can be transmitted automatically.
  • the errors can then be corrected automatically, for example, with the embodiment described above.
  • a processing machine 01 is preferably embodied as a sheet processing machine 01, in particular as a die-cutting machine 01, more preferably as a rotary die-cutting machine 01, for processing at least one, preferably at least two, more preferably a large number of sheet-like substrates 02 or sheets 02.
