Description

The invention relates to a machining tool of a processing machine and a method for dressing a machining tool according to the preamble of claim 1 or claim 7.

When manufacturing packaging, materials in web or sheet form are processed. In several processing steps, the sheets are printed, embossed, grooved, perforated, punched, cut, stapled, glued and folded into packaging, for example.

To make optimal use of the surface area of a sheet, several identical or different copies, e.g. of a poster, a folding box or packaging, are usually printed on a single sheet and then punched. These copies are referred to as a panel. 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 mold-based 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 a cutting, perforating, embossing and/or creasing machine. In addition to rotary punching machines, there are also Flat die cutters, especially flatbed die cutters. In these, several sheets are processed one after the other using a cyclically repeating movement.

By using rotary die-cutting machines, significantly higher production speeds can be achieved due to the continuous movement process. Rotary die-cutting machines can be equipped with the following modules: punching unit, creasing unit, embossing unit and stripping unit. Such a rotary die-cutting machine is, for example, from the WO 2017/089420 A2 known.

Manufacturing tolerances of tools or different load distribution during processing, especially punching, can lead to wear on the blades or tools with height differences. This results in, for example, uneven punching pressure, which can lead to an unclean punching result. The punching tools and/or grooving tools and/or embossing tools must be reworked to compensate for the errors and/or deviations. To do this, a substance is applied to the back of the respective processing tool. This is called dressing the processing tools.

The EP 2 327 521 A1 discloses, for example, a method for trimming punching tools in flatbed punches. In flatbed punches, 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 blades. The errors and/or deviations are compensated for by gluing the back of the punching and/or creasing blades. Due to the relatively high tolerances in the flatbed area, the punching tool can be trimmed sufficiently well with the adhesive tape. Such adhesive tape is available in different thicknesses. Alternatively, (trimming) sheets can be used for trimming with the required basic contour to ensure precise application of the layers to compensate for the cutting heights. (Trimming) sheets made 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 EN 10 2012 017 636 A1 discloses a processing tool of a processing machine, in particular a flatbed punch. The processing tool comprises an upper tool and a wooden support plate. A trimming sheet is arranged between them. A swelling agent can be used for trimming on the trimming sheet.

Also the DE 20 2013 100 883 U1 discloses a trimming sheet of a strip steel punching tool.

Through the EP 3 342 568 B1 is a system for compensating for misalignment of a die for die cutting cardboard. Height correcting elements can be captured and a digital representation of the digital file can be projected onto a pressure compensation plate of the die cutter.

The EP 0 418 768 A2 discloses a punching sheet, tool and a method for manufacturing. Negative tolerances that arise when grinding the punching edges can be compensated with a layer of plastic, e.g. liquid two-component phase, on the back of the punching sheet.

Differences in the machining contour or cutting height also occur with rotary punching. Due to the rotating process, less deformation due to lower punching pressures and the high-precision manufacturing process of the cutting contours with CNC milling, the tolerances of the cutting edges that need to be corrected are significantly lower. As a rule, layers with a thickness of 5-10 micrometers are sufficient to compensate.

The invention is based on the object of creating a machining tool of a processing machine and a method for dressing.

The object is achieved according to the invention by the features of claim 1 and claim 7.

The advantages that can be achieved with the invention are in particular that it enables an operator to make quicker and easier preparations. A preparation sheet behind the processing tool, in particular the punching tool, can be dispensed with. The complex production and/or storage of the preparation sheet, which entails costs in addition to the costs of the processing tools, in particular the punching and/or creasing tools, can be dispensed with. A preparation sheet not only has to be produced and/or archived in addition to the tool costs, but also becomes damaged over time through repeated use and then has to be remade, which is costly and time-consuming. In particular, the invention is not limited to rotary processing methods, but is also particularly suitable for use in flat and cyclically guided processing methods. Preparation is also useful in flatbed punches, since there too the use of preparation agents means that conventional preparation sheets can be dispensed with. Depending on the use of the preparation agent, even larger deviations can be compensated for.

Another advantage that can be achieved with the invention is that the time for trimming is minimized and handling is improved. In particular, a digital processing contour is used for this purpose. The digital processing contour of the processing tool can be determined, for example, from a pre-processing stage, for example a punching pre-stage and/or pre-printing stage. After inspecting the processing tool and/or the processing result, areas on the digital processing contour can be marked. For inspection, for example, a sample 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. Preferably, marking is done at a control station, where the processing contour or the cutting layout is displayed and the areas to be reworked (trimming) are directly indicated. using an input device. However, markings in mobile devices are also conceivable and useful. In principle, any digital input device can be used for this. This digital data can then be used in different ways to make it easier to prepare the machining tool and, if necessary, to automate it. For example, this data can also be saved and called up again at any time. In particular, when using preparation sheets, the work result cannot/could not be saved and one had to be created again.

For example, such a simplification is achieved by coupling it with 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 can quickly and easily identify the places where a finishing agent must be applied. The finishing points are thus easily identified. A short-throw projector is particularly preferred for this purpose, as this saves space in particular. A liquid finishing agent is used to make operation even easier. This can be hardened using radiation, in particular UV radiation, for example.

Additionally or alternatively, the digital data can be passed directly to a control system for controlling an adjusting arm. The adjusting arm can then, for example, apply the trimming agent fully automatically. The controlled arm can, for example, communicate using a machine control system and receive signals from a quality control system, for example. For example, such a quality control system is arranged in different areas of the punching machine and/or can also be arranged on upstream machines, such as printing machines and/or downstream on folding and/or gluing machines. In particular, different processes can be linked together in this way and automation can be further advanced. There is no need for complex and/or inaccurate 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 that is to be applied. The controlled arm takes care of the rest automatically. For example, curing is also fully automatic. In this embodiment, for example, projection could be dispensed with.

A further advantage that can be achieved with the invention is in particular that the machining tool is prepared directly in the machining machine. In a further automated embodiment, the machining tool is removed from the machining machine semi- and/or fully automatically, for example similar to a plate changing machine on a printing press, and the preparation agent is applied fully automatically using the digital data, for example with the actuating arm. A machining tool, in particular a punching plate, can then be automatically spot-painted and then hardened directly in a plate changing machine. This would eliminate the need to remove the punching plate from the shaping unit or the punching tower, for example. In the case of a fully automatic plate changing machine, an operator does not even have to leave the control station. After hardening, the plate can be fed back in using the plate changing machine.

A further advantage that can be achieved with the invention is that the finishing is carried out using an applyable paint and/or paint mixture. Spray paints are usually used for surface and/or zone-wise application. This allows an operator to finish the work faster and easier. Precise lines can be applied to small areas using touch-up pens. Preferably, such a paint can be applied and then hardened. The waiting time for the paint to dry can be minimized by using a blasting device, preferably a large-area one. Preferably, such a blasting device is attached to a fixed structure so that incorrect blasting can be avoided and better protection for an operator can be guaranteed. In particular, this allows faster curing and/or drying over the entire surface. Preferably, such curing is carried out using UV light. Such a process has the advantage that the varnish can be applied very precisely and that curing can be carried out in a very controlled manner. When the varnish is cured using UV radiation, for example, a scratch-resistant layer is created which has sufficient temperature resistance and resistance to mechanical stress for use in a punching machine. In particular, thin layers with the required tolerances of 5-10 µm can be achieved. For example, a layer thickness can be set depending on the mixing ratio of the varnish, for example with alcohol. Layer thicknesses between 5 and 15 micrometers can be achieved. Preferably, the UV varnishes are cured over a large area using a UV LED, which is preferably arranged on the device for dressing. The dressing thus carried out can be removed very easily after the large area has been hardened and/or dried. Overall, post-processing and/or dressing is therefore easier to apply and handling of the necessary tools is significantly simplified. In addition, the dressing can be applied very precisely and only cutting contours that actually need to be dressed can be reworked. With large-area zone dressing, zones that were already sufficient in terms of cutting quality are already dressed. This can be avoided. In addition, the dressings are scratch-resistant, mechanically resistant and resistant to the temperatures introduced into the punching cylinder (temperature-resistant). Due to the rapid hardening and/or drying, the operator's waiting time during dressing can be minimized.

Alternatively or in addition to the curable dressing agent, the dressing agent can be a dispersion consisting of a dispersion medium and a disperse phase. The dispersion medium contains at least one, preferably slightly volatile, solvent. The disperse phase consists of a finely distributed solid. This remains when the solvent evaporates and can be used for dressing. Very thin layers can be applied. The dispersion is particularly easy to apply using an applicator pen and can be applied automatically using an actuator arm. The dispersion is also characterized by a high proportion of highly volatile solvents. This means that drying times can be kept very short. For example, a drying time of just a few seconds can be achieved. Such a dispersion particularly preferably has a ketone as the solvent, preferably methyl ethyl ketone (MEK for short). The solvent evaporates very quickly, which leads to the dispersion drying quickly. In particular, the remaining particles and/or pigments of the dispersion form a robust layer that 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%, of solvent. The layer thickness of the finishing layer can be easily adjusted by adjusting the proportion of solvent. A dispersion that has finely distributed particles, in particular pigments, is particularly advantageous. Preferably, the dispersion for dressing is an ink, more preferably an inkjet ink. Ink has the advantage that it is inexpensive and readily available. Furthermore, inkjet ink poses hardly any danger to the operator. There is also no need for radiation for drying. Particularly preferably, the ink can also be applied automatically using an inkjet printing device.

A further advantage that can be achieved with the invention is in particular 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, using the previously described embodiment.

Preferably, at least one computer is arranged in operative connection with a digital pre-press file, in particular a digital punch pre-press file, and/or is arranged to be retrievable. The at least one projection device is arranged to project at least the digital punch pre-press contour onto the support surface 351. When the The machining contour and/or the cutting contour is projected onto the rear side of the machining tool so that it matches the front side. In particular, an operator can then easily dress the machining tool 301 and apply the dressing agent 361 to the appropriate dressing points 358.

At least one agent that is liquid when applied is used as the dressing agent 361. The dressing agent 361 is applied to the processing tool 301. During operation, the dressing agent 361 is applied, preferably directly, between the dressed processing tool 301 and the punching cylinder. In particular, the dressing agent 361 is then arranged in contact with the back of the processing tool and the punching cylinder. As a result, the dressing agent, which has now hardened, exerts a force on the processing tool 301 and thus indirectly causes a change in the cutting height of the processing tool 301 in the radial direction to a punching cylinder.

The at least one finishing agent 361 is applied in a liquid state to each finishing point 358 and preferably dried after application, preferably by means of radiation, more preferably by means of UV radiation. The at least one chemical cross-linking reaction, through which the curing and/or drying takes place, can be initiated by means of UV radiation. Such a process and/or such a reaction is usually referred to as photopolymerization. The finishing agent 358 and/or the UV varnish becomes very hard and scratch-resistant and a It can be applied several times to achieve thicker layers. The finishing agent 361 can be dried easily by blasting the surface of the processing tool.

The at least one device for dressing 350 has at least one jet device 354, more preferably several, in particular two or four, jet devices 354. The at least one jet device 354 is preferably arranged to radiate onto the support surface 351. For example, the jet device 354 is arranged in a bar which preferably covers the entire width of the support surface. The at least one jet device 354 can be moved, for example via a rolling device, preferably over the entire length of the support surface. In another preferred embodiment, the at least one jet device 354 is flat and arranged in a folding device 365. This can be closed and is then arranged parallel to the support surface 351. The at least one jet device 354 then preferably irradiates the entire support surface 351 at once. In a further embodiment, several folding devices 365 are arranged on the device for dressing 350 and these cover different zones of the support surface 351. When the folding device 365 is folded in, the underlying support surface 351 is covered and the at least one jet device 354 irradiates this respective zone of the support surface 351. Preferably, four folding devices 359, each with a jet device 354, are then arranged. When all four folding devices 365 are folded in, the entire support surface 351 has preferably been and/or is being irradiated. This surface irradiation quickly hardens a dressing agent 361. Preferably, the at least one jet device 354 is designed as a UV jet device 354, in particular a UV LED jet device 354, and is arranged to emit UV radiation. However, hardening is not intended for dressing by applying a dispersion.

The at least one finishing agent 361 is preferably applied by means of a pen 362, preferably a touch-up pen 362, more preferably a UV touch-up pen 362. Such a Pen 362 preferably has a storage container and a felt tip 364. The finishing agent 361 passes from the storage container 363 to the at least one finishing point 361 via the felt tip 364, preferably by pressing on the pin 362.

Each dressing point 358 at which the at least one dryable dressing agent 361 is used has at least one layer. Such a layer thickness for a single application is between 5 and 15 µm and thus corresponds to the necessary accuracy when dressing processing tools 301 in rotary or flat processing methods. A more precise setting of a layer thickness can be undertaken via a mixing ratio of the at least one dressing agent 361.

Even when hardened, the product can be easily removed by scratching, for example with a spatula.

In another preferred embodiment, the at least one trimming agent 361 is applied to the trimming points 358 via a robot arm and/or via a preferably controlled actuating arm. The at least one actuating arm is arranged to be movable above the support surface 351 of the device for trimming 350. The at least one actuating arm is preferably arranged to be controllable by means of the digital processing contour 356 and the markings 357. For example, such an actuating arm holds the pin 362 and applies the trimming agent 361 to the appropriate trimming points 358 by means of a control by means of the data of the processing culture in Connection with the markings 357 are processed and converted into signals for the actuating arm. The actuating arm then applies the dressing agent 361 to the dressing points 358 without any intervention and/or automatically.

In a further preferred embodiment, the actuating arm has a nozzle from which the dressing agent 361 can be applied directly. In this embodiment, the pin 362 can be dispensed with and the dressing agent 361 is pumped, for example, from a tank directly to the nozzle of the actuating arm and there discharged in a metered manner onto the at least one dressing test point 358. Preferably, a projection device 353 can be dispensed with in this embodiment.

In a further embodiment, the points that need to be trimmed on the processing tool 301 can be identified using a mobile device. For example, a preview of the processing contour and/or the cutting contour can be transmitted to the mobile device using the digital processing pre-stage, so that an operator can then mark points for post-processing there. The data and/or markings 357 can then be transmitted to the device for trimming.

In an even more highly automated embodiment, a processing machine 01 has a semi-automatic and/or fully automatic tool changing machine. The device for dressing is then arranged in operative connection with a plate changing machine. A device for dressing 350 can be integrated into such a tool changing machine. The dressing agent 361 is preferably applied after the processing tool 301 has been ejected from a plate changing device. For example, this can fully automatically cover the dressing points 358 with dressing agent 361 and/or apply the dressing agent 361. For example, a controlled actuating arm is also used here. The dressing agent 361 is preferably in a shaping unit 300; 400; 500; 600. For this purpose, the device for dressing is at least partially integrated into a shaping unit 300; 400; 500; 600.

In a further preferred embodiment, the processing machine has an inspection device for inspecting the processing result. In this case, marking of the processing contour from the digital processing preliminary stage can also be dispensed with. In conjunction with the tool changing machine and a controlled actuating arm arranged thereon, the processing tool 301 can then be fully automatically adjusted. In addition to the method steps already mentioned, the adjustment is described again step by step below.

A processing tool 301 is trimmed in a process comprising several steps. Trimming refers in particular to the reworking and/or compensation of errors and/or deviations in the tool geometry using at least one trimming device 361. To do this, the places on the processing tool 301 that need to be trimmed must first be identified. As a rule, a test sheet is processed, in particular punched, for this purpose. An operator and/or an inspection device assess the processing result based on this test sheet or on a processing contour of the processing tool 301. The at least one device for trimming 350 preferably has at least one inspection device for inspecting a test sheet and/or the processing contour of the processing tool 301. Errors in the processing result are assigned to places on the processing tool 301. In particular, this is preferably done using a digital display on which the processing contour of the processing tool 301 is displayed using data from the digital pre-stage. In this machining contour, markings 357 are used to mark points, in particular trimming points 358, where the machining result is unsatisfactory. Alternatively and/or additionally, errors on the machining tool 301 can also be detected directly. by removing it from the processing machine 01, for example in a plate changing machine. This embodiment preferably has a support surface 351, since the liquid dressing agent 361 must be applied horizontally. Alternatively, the dressing agent 361 would have to be hardened very quickly by means of the blasting device 354.

Preferably, the digital processing contour 356 is saved with the marked trimming points 358 and can be called up again at any time, for example if the trimming agent 361 dissolves over time. The hardened trimming agent 361 can be easily removed from the back of the processing tool 301 using a spatula.

According to the invention, the dressing agent 361 is a dispersion consisting of a disperse phase and a dispersion medium. The dispersion particularly preferably has a proportion of the dispersion medium of at least 50%, more preferably of at least 60%, even more preferably of at least 70%, or more.

A volatile solvent is preferably used as the dispersion medium. The volatility of substances is often specified in reference to the vapor pressure of diethyl ether. Volatility is also preferably specified as an evaporation number according to DIN 53170. The time in which a substance evaporates completely (evaporation time) is compared with the time that diethyl ether needs to evaporate. A high evaporation number means relatively slow evaporation, i.e. low volatility. A low evaporation number means faster evaporation, i.e. relatively high volatility. In accordance with the literature, highly volatile solvents are particularly preferably those that have an evaporation number of less than 10. In particular, the use of highly volatile solvents ensures a short drying time.

Solvents from the group of ketones are particularly preferably used as solvents for the dispersion. These often have evaporation numbers between 1 and 5, more preferably between 2 and 3. A preferred solvent is, for example, acetone and/or butanone (often methyl ethyl ketone, MEK for short). Acetone and butanone are characterized by their high availability. Methyl ethyl ketone generally has an evaporation number of 2.7 and acetone 2.1.

In a preferred embodiment, the dispersion has a proportion of at least 50%, more preferably at least 60%, even more preferably at least 70% methyl ethyl ketone. The dispersion preferably has a concentration of 60-75% by weight of butanone. More preferably, the dispersion additionally has a 5-10% by weight proportion of acetone. Furthermore, the dispersion can also have a proportion, preferably less than 5%, of 1-methoxy-2-propanol.

The disperse phase preferably consists of finely distributed solid particles. Such particles are preferably formed as pigments, in particular color pigments. The pigments are preferably those that are used in inks and in particular in inkjet inks and contribute to the coloring. For example, soot particles are used as pigments. Soot particles are characterized by their high availability. In particular, industrial carbon black is the most widely used black pigment. Depending on the color of the dispersion or ink, other pigments are used.

The dispersion is also preferably an ink, in particular an inkjet ink. Inkjet inks in particular have a high proportion of volatile solvents and/or volatile solvents. Such inks mainly contain volatile ketones as solvents. Solid pigments are also finely distributed in the inks. These remain after the solvents have evaporated. A particularly suitable ink and/or dispersion has a proportion of between 60% and 75% butanone. In addition Such an ink contains solid particles. These are often color-giving pigments, such as soot in black ink. Such inks, especially inkjet inks, are particularly suitable as finishing agents. After the solvents have evaporated, the solids remain. These solids then form a layer thickness that can be used for finishing. The layer thickness is preferably between 2 micrometers and 15 micrometers. This layer is scratch-resistant, heat-resistant and pressure-resistant. The layer preferably has around 4-5 micrometers with each application. By applying it several times, a finishing thickness of between 4 and 15 micrometers can easily be achieved.

The dispersion is applied to the dressing point 358 for dressing, preferably using the pen 362. Analogous to the varnish, the dispersion is applied directly to the back of the processing tool 301. The highly volatile solvents of the dispersion evaporate in a short time and a layer with a layer thickness remains. This happens in a few minutes, preferably in less than 30 seconds. The inkjet ink described above is preferably used for dressing. A particular advantage of using ink is that existing inkjet systems can be used for dressing. This makes automating the dressing particularly easy. All that is needed is an inkjet printing system to be arranged above the support surface 358 without major adjustments and dressing can be done easily using the digital prepress file. A manually and/or automatically controllable inkjet printing system is used for this purpose. For example, such an inkjet printing system can comprise a continuous inkjet print head or have droplet-wise ejection. The inkjet head can be controlled manually and guided to the desired position or can be integrated into the PLC control of the punching machine via a fully automatic x-y axis with a rotating head.

The operator would mark the positions on the control panel that are to be adjusted The corresponding area can then be scanned with the print head.
