Description

[0001] The invention relates to a device for preparing a punching tool according to the preamble of claim 1 and to a method according to claim 7.

[0002] In the production of packaging, web- or sheet-like materials are processed. In several processing steps, the sheets are printed, embossed, scored, perforated, punched, cut, stapled, glued, and folded into packaging, for example.

[0003] To maximize the surface area of ​​a sheet, several identical or different copies, e.g., a poster, a folding box, or packaging, are usually printed on a single sheet and then die-cut. These copies are referred to as a "multiple" sheet. A sheet processing machine can comprise various processing steps such as printing, cutting, embossing, creasing, punching, perforating, gluing, and / or stapling. Such sheet processing machines often also include inspection devices. Sheets are typically processed and trimmed in processing machines with die-cutting and cutting devices.

[0004] Such a processing machine is designed, for example, as a punching, cutting, perforating, embossing, and / or creasing machine. When such a processing machine is referred to below as a punching and / or die-cutting machine, this also specifically refers to a cutting, perforating, embossing, and / or creasing machine. In addition to rotary die cutters, die-cutting systems also include flat-bed die cutters, particularly flatbed die cutters. These process multiple sheets one after the other using a cyclically repeating movement.

[0005] The use of rotary die-cutting machines allows for significantly higher production speeds due to the continuous motion process. Rotary die-cutting machines can be equipped with modules such as a punching unit, creasing unit, embossing unit, and stripping unit. One such rotary die-cutting machine is known, for example, from WO 2017 / 089420 A2.

[0006] Manufacturing tolerances of tools or varying load distribution during processing, especially punching, can lead to wear on knives or tools with height differences. This results, for example, in uneven punching pressure, which can lead to an uneven punching result. The punching tools and / or creasing tools and / or embossing tools must be reworked to compensate for the errors and / or deviations. For this purpose, a compound is applied to the back of the respective processing tool. This process is referred to as dressing the processing tools.

[0007] EP 2 327 521 A1, for example, discloses a method for trimming punching tools in flatbed die cutters. In flatbed die cutters, trimming is usually carried out using special adhesive tape and / or special adhesive strips, which compensate for unevenness and / or deviations and / or defects on the blades. The defects and / or deviations are compensated for by back-gluing 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 various thicknesses. Alternatively, for precise application of the layers to compensate for the cutting heights, trimming sheets with the required basic contour can be used. 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.

[0008] The publication DE 10 2012 017 636 A1 relates to a method for determining the machine-dependent trimming requirement of a punching and embossing machine, whereby a tool-specific trimming requirement is read from a database. Trimming requirement values ​​or a trimming requirement factor are assigned to a respective tool type in the database.

[0009] DE 10 2013 016 755 A1 discloses a device for dressing flatbed punching and / or embossing machines, wherein the dressing is provided by targeted control of heating cartridges in a plurality of aluminum metal blocks arranged next to one another in a matrix. The heating cartridges are controlled by a control unit via a bus system of a machine control system. Furthermore, memories are provided that contain tool-dependent dressing requirements, and thus the heating cartridges in the respective metal blocks are controlled accordingly.

[0010] From the generic EP 3 342 568 A1, a system for compensating misalignments of a die for punching cardboard is known. Height-correcting elements can be detected in order to project a digital representation of the digital file onto a pressure compensation plate of the punch. EP 3 342 568 A1 discloses a device for adjusting a pressure compensation plate of a punch. The pressure compensation plate is arranged either between the processing tool and the punch or beneath the counter-pressure surface. The processing tool itself is thereby adjusted as indirectly as possible. A correction template, previously recorded by a camera, is projected onto the pressure compensation plate by means of a projector. The correction template corresponds to a representation of height-compensation adhesive tape. DE 20 2013 100 883 U1 also discloses a make-ready sheet for a steel strip punching tool.

[0011] EP 0 418 768 A2 discloses a punched sheet, a method for its production, and a tool for carrying out the method. Negative tolerances that arise during grinding of the punched edges can be compensated for with a layer of plastic, e.g., a liquid two-component phase, on the back of the punched sheet.

[0012] Even with rotary punching, differences in the machining contour or cutting edge height occur. Due to the rotating process, reduced deformation due to lower punching pressures, and the high-precision manufacturing process of the cutting contours using CNC milling, the cutting edge tolerances that need to be corrected are significantly smaller. Layers with thicknesses of 5-10 micrometers are usually sufficient for compensation.

[0013] The invention is based on the object of creating a device and a method for dressing.

[0014] The object is achieved according to the invention by the features of claim 1 and claim 7.

[0015] The advantages achievable with the invention are, in particular, that it enables an operator to make trimming faster and easier. A trim sheet behind the processing tool, in particular the punching tool, is thereby dispensed with. The complex production and / or storage of the trim sheet, which incurs costs in addition to the costs of the processing tools, in particular the punching and / or creasing tools, is dispensed with. A trim sheet not only has to be continually 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.Trimming is also useful in flatbed die cutters, as the use of trimming agents eliminates the need for conventional trim sheets. Depending on the trimming agent used, even larger deviations can be compensated.

[0016] A further advantage that can be achieved with the invention is, in particular, that the time required for preparation is minimized and handling is improved. In particular, a digital machining contour is used for this purpose. The digital machining contour of the machining tool can be determined, for example, from a preliminary machining stage, for example a punching pre-stage and / or pre-printing stage. After inspection of the machining tool and / or the machining result, areas on the digital machining contour can be marked. For inspection, for example, a test sheet is machined or the contours of the machining tool are viewed directly. This is done either by an operator or fully automatically using an integrated inspection device. Marking is preferably done at a control station where the machining contour orThe cutting layout can be displayed, and the areas requiring rework (preparation) can be marked directly using an input device. However, markings on mobile devices are also conceivable and useful. In principle, any digital input device can be used for this purpose. This digital data can then be used in various ways to facilitate and, if necessary, automate the preparation of the machining tool. For example, this data can also be saved and retrieved at any time. Especially when using preparatory sheets, the work result could not / could not be saved, and a new one had to be created.

[0017] Such simplification is achieved by coupling it with a projection device. The machining tool is positioned in an aligned manner, and the machining contour with the markings is projected onto the back of the machining tool. An operator can quickly and easily identify the locations 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 it offers particular space savings. For further ease of operation, a liquid finishing agent is used. This can be cured, for example, using radiation, especially UV radiation.

[0018] Additionally or alternatively, the digital data can be passed directly to a controller for controlling a positioning arm. The positioning arm can then, for example, apply the finishing agent fully automatically. The controlled arm can, for example, communicate via a machine control system and receive signals, for example from a quality control system. For example, such a quality control system is arranged in various areas of the die-cutting 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, this allows different processes to be linked with one another and automation to be further advanced. Complex and / or inaccurate manual finishing can be dispensed with. Additional labor costs can be saved. For example, an operator would only have to select the UV layer thickness to be applied.The controlled arm takes care of the rest automatically. Curing, for example, is also fully automated. In this embodiment, projection could be omitted.

[0019] A further advantage achievable with the invention is, in particular, that the dressing of the processing tool takes place directly in the processing machine. In a further automated embodiment, the processing tool is removed from the processing machine semi-automatically and / or fully automatically, for example similar to an automatic plate changer on a printing press, and the dressing agent is applied fully automatically using the digital data, for example with the actuating arm. A processing tool, in particular a cutting plate, can then, for example, be automatically spot-coated and subsequently hardened directly in an automatic plate changer. This would eliminate the need to remove the cutting plate, for example, from the forming unit or the punching tower. In the case of a fully automatic plate changer, an operator does not even have to leave the control station. After hardening, the plate can be fed back in using the automatic plate changer.

[0020] A further advantage achievable with the invention is, in particular, that dressing is carried out using an applyable lacquer and / or lacquer mixture. Spray lacquers are usually used for surface and / or zone-wise application. This allows the operator to dress faster and easier. Precise lines can be applied to small areas using touch-up pens. Such a lacquer can preferably be applied and then cured. Waiting time for the lacquer to dry can be minimized by using a blasting device, preferably one with a large area. Such a blasting device is preferably attached to a fixed structure so that incorrect blasting can be avoided and better protection for the operator can be guaranteed. In particular, this enables faster curing and / or drying over the entire surface.Such curing is preferably carried out using UV light. This process has the advantage that the lacquer can be applied very precisely and that curing can be carried out in a very controlled manner. When the lacquer is cured using UV radiation, for example, a scratch-resistant layer is created which has sufficient temperature stability 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 produced. For example, a layer thickness can be adjusted depending on the mixing ratio of the lacquer, e.g. with alcohol. Layer thicknesses between 5 and 15 micrometers can be achieved. The UV lacquers are preferably cured over a large area using a UV LED, which is preferably arranged on the preparation device.The dressing applied in this way can be removed very easily after a large area has been hardened and / or dried. Overall, this makes post-processing and / or dressing easier to apply and handling of the necessary tools is significantly simplified. In addition, the dressing can be applied very precisely and only those cutting contours that actually need to be dressed are 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 durable, and resistant to the temperatures introduced into the punching cylinder (temperature-resistant). Due to the rapid curing and / or drying, the operator's waiting time during dressing can be minimized.

[0021] 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 highly 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 easily applied using an applicator pen and can be applied automatically using an actuating arm. The dispersion is also characterized by a high proportion of highly volatile solvents. This allows drying times to be kept very short. For example, a drying time of just a few seconds can be achieved. Such a dispersion particularly preferably contains a ketone, preferably methyl ethyl ketone (MEK for short), as the solvent.The solvent evaporates very quickly, which leads to rapid drying of the dispersion. 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 solvent content of at least 50%, more preferably at least 60%, even more preferably 70%. By adjusting the solvent content, the layer thickness of the dressing layer can be easily adapted. A dispersion containing finely distributed particles, in particular pigments, is particularly advantageous. The dressing dispersion is preferably an ink, more preferably an inkjet ink. Ink has the advantage of being inexpensive and readily available. Furthermore, inkjet ink poses hardly any risks to the operator. Radiation for drying can also be dispensed with.Particularly preferably, the ink can also be applied automatically using an inkjet printing device.

[0022] A further advantage that can be achieved with the invention is in particular that the processing tools, preferably punching tools, can be inspected by means of a mobile device and detected errors can be transmitted automatically.

[0023] The errors can then be corrected automatically, for example, using the previously described execution.

Height differences and / or unevenness resulting from these errors and / or deviations must be compensated for or reworked by the at least one dressing means 361. For this purpose, the at least one dressing means 361 is applied and / or applied to the machining tool.Preferably, the at least one machining tool has at least one location where the at least one trimming agent 361 must be and / or is applied.

For dressing, the processing tool 301 is preferably placed on the support surface 351 with the back side and / or side facing away from the processing contour. Dressing accordingly takes place on the back side of the processing tool 301 and / or the side facing away from the processing contour. In particular, an agent is applied to the back side in order to compensate for geometric differences in the tool, for example on the front side in the processing contour. The dressing agent 361 is applied to the back side and / or the side facing away from the processing contour. In particular, the relative distance of the processing tool 301 to a processing cylinder or, in the case of a flatbed punch, to a punching platen is adjusted.This allows for inaccuracies in the machining result, such as punching, to be addressed.

The at least one projection device 353 is arranged and / or can project a projection onto the support surface 351 and / or in particular onto the back of the at least one processing tool 301. During dressing, a projection device 353 projects a processing contour and / or a cutting contour of the front side of the processing tool 301 onto the back. Additionally or alternatively, markings 357 can be projected, for example, around dressing points 358 of a processing tool 301. In a preferred embodiment, the at least one device for dressing 350 is integrated into a control station of the processing machine 01.

[0073] In a first embodiment, in particular, at least one projection device 353 is arranged to retrieve the digital machining contour and to project it onto the support surface 351 by means of the at least one digital machining contour and / or cutting contour. The projection device 353 is arranged to project at least parts of the machining contour 356 onto the support surface 351 and / or, in the presence of the machining tool 301, onto the at least one machining tool 301, in particular the rear side, by means of the digital machining contour 356. The at least one projection device 353 is additionally arranged to project the markings 357 onto the support surface 351 and / or, in the presence of the machining tool 301, onto the at least one machining tool 301. In particular, the at least one projection device 353 is arranged in operative connection with a computer and / or a controller.Preferably, at least one computer is operatively connected to a digital pre-press file, in particular a digital punching pre-press file, and / or arranged to be retrievable. The at least one projection device is arranged to project at least the digital punching pre-press contour onto the support surface 351. When the processing tool is placed on the support surface, the processing contour and / or the cutting contour is projected onto the rear side so that it matches the front side. In particular, an operator can then easily adjust the processing tool 301 and apply the dressing agent 361 to the appropriate dressing points 358.

[0074] At least one agent that is liquid upon application is used as the finishing agent 361. A curable and / or dryable agent is preferably used for the finishing agent 361. Such a finishing agent 361 is preferably curable and / or dryable by means of a chemical crosslinking reaction. Preferably, the at least one finishing agent 361 in the liquid state is a lacquer and / or lacquer mixture that can be converted into a solid state by crosslinking reactions. Curing refers in particular to a chemical structural change of the finishing agent 361. Further preferably, such a finishing agent 361 is an ink, for example an inkjet ink. Such an inkjet ink has the advantage that it dries quickly and forms a dimensionally stable layer.

[0075] The at least one finishing agent 361 is applied in a liquid state to each finishing point 358 and is preferably cured and / or dried after application, preferably by means of radiation, more preferably by means of UV radiation. The at least one chemical crosslinking 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 repeated application is possible to achieve greater layer thicknesses. The finishing agent 361 can be easily dried by irradiating the entire surface of the processing tool.

[0076] The at least one dressing device 350 has at least one blasting device 354, more preferably several, in particular two or four, blasting devices 354. The at least one blasting device 354 is preferably arranged to radiate onto the support surface 351. For example, the blasting device 354 is arranged in a bar which preferably covers the entire width of the support surface. For example, the at least one blasting device 354 is movable, preferably over the entire length of the support surface, via a rolling device. In another preferred embodiment, the at least one blasting 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 blasting device 354 then preferably irradiates the entire support surface 351 at once.In a further embodiment, a plurality of folding devices 365 are arranged on the dressing device 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 this respective zone of the support surface 351 is irradiated by the at least one radiation device 354. Preferably, four folding devices 359, each with a radiation device 354, are 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 cures a dressing agent 361. Preferably, the at least one radiation device 354 is designed as a UV radiation device 354, in particular a UV LED radiation device 354, and is arranged to emit UV radiation.

[0077] The at least one finishing agent 361 is preferably applied using a pen 362, preferably a touch-up pen 362, more preferably a UV touch-up pen 362. Such a pen 362 preferably has a reservoir and a felt tip 364. The finishing agent 361 is conveyed from the reservoir 363 to the at least one finishing point 361 via the felt tip 364, preferably by pressing the pen 362.

[0078] Each dressing point 358 at which the at least one curable and / or 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 required accuracy for dressing processing tools 301 in rotary or flat machining processes. A more precise adjustment of a layer thickness can be achieved via a mixing ratio of the at least one dressing agent 361, in particular the lacquer mixture. The at least one dressing agent 361 differs in the alcohol content and the thickness tolerances after drying.

[0079] The thinnest layer, with a comparatively high alcohol content, results in a layer thickness of approximately 5 µm in a single application, which is exactly sufficient. Different mixing ratios can be used. By reducing the alcohol content, the layer thickness can be increased.

[0080] Even in the hardened state, this can be easily done by scratching the product, for example using a spatula.

[0081] In another preferred embodiment, the at least one dressing agent 361 is applied to the dressing 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 dressing device 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, by means of a control, applies the dressing agent 361 to the appropriate dressing points 358. The control system processes the data of the processing culture in conjunction with the markings 357 and converts these into set 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.

[0082] In a further preferred embodiment, the actuating arm has a nozzle from which the finishing agent 361 can be applied directly. In this embodiment, the pin 362 can be omitted, and the finishing agent 361 is pumped, for example, from a tank directly to the nozzle of the actuating arm and discharged there in a metered manner onto the at least one finishing test point 358. Preferably, a projection device 353 can be omitted in this embodiment.

[0083] In a further embodiment, the areas on the machining tool 301 that require trimming can be identified using a mobile device. For example, a preview of the machining contour and / or the cutting contour can be transmitted to the mobile device using the digital pre-processing stage, so that an operator can then mark the areas requiring re-processing. The data and / or markings 357 can then be transmitted to the trimming device.

[0084] In an even more highly automated embodiment, a processing machine 01 has a semi-automatic and / or fully automatic tool changing machine. The dressing device is then arranged in operative connection with a plate changing machine. A dressing device 350 can be integrated into such an automatic tool changing machine. The dressing agent 361 is preferably applied after the processing tool 301 has been discharged 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 applied in a shaping unit 300; 400; 500; 600. For this purpose, the dressing device is at least partially integrated into a shaping unit 300; 400; 500; 600.

[0085] In a further preferred embodiment, the processing machine has an inspection device for inspecting the processing result. This also eliminates the need to mark the processing contour from the digital pre-processing stage. In conjunction with the automatic tool changer and a controlled positioning arm arranged thereon, fully automatic dressing of the processing tool 301 can then be performed. In addition to the method steps already mentioned, the dressing process is described again step by step below.

[0086] 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 means 361. For this purpose, the areas on the processing tool 301 that need to be trimmed must first be identified. Typically, 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. Preferably, the at least one trimming device 350 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 areas on the processing tool 301.In particular, this is preferably done by a digital display on which the machining contour of the machining tool 301 is shown using data from the digital pre-stage. Markings 357 mark locations in this machining contour, in particular trimming locations 358, where the machining result is unsatisfactory. Alternatively and / or additionally, errors on the machining tool 301 can also be detected directly, for example, by removing it from the machining machine 01 in an automatic plate changing device. This embodiment preferably has a support surface 351, since the liquid trimming agent 361 must be applied horizontally. Alternatively, the trimming agent 361 would have to be cured very quickly by means of the jet device 354.

[0087] Preferably, the digital machining contour 356 is saved with the marked trimming points 358 and can be retrieved at any time, for example, if the trimming agent 361 dissolves over time. Using a spatula, the hardened trimming agent 361 can be easily removed from the back of the machining tool 301.

[0088] Additionally or alternatively, the finishing agent 361 is a dryable agent such as a dispersion consisting of a disperse phase and a dispersion medium. The dispersion particularly preferably has a dispersion medium content of at least 50%, more preferably at least 60%, even more preferably at least 70%, or more.

[0089] 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. This relates the time in which a substance evaporates completely (evaporation time) to the time required for diethyl ether to evaporate. A high evaporation number means relatively slow evaporation, thus low volatility. A low evaporation number means faster evaporation, thus relatively high volatility. In accordance with the literature, highly volatile solvents are particularly preferably those with an evaporation number of less than 10. In particular, the use of highly volatile solvents ensures a short drying time.

[0090] Solvents from the ketone group are particularly preferred as solvents for the dispersion. These often have evaporation rates between 1 and 5, more preferably between 2 and 3. A preferred solvent is, for example, acetone and / or butanone (often methyl ethyl ketone, or MEK for short). Acetone and butanone are characterized by their high availability. Methyl ethyl ketone generally has an evaporation rate of 2.7 and acetone of 2.1.

[0091] In a preferred embodiment, the dispersion contains at least 50%, more preferably at least 60%, even more preferably at least 70% methyl ethyl ketone. The dispersion preferably has a butanone concentration of 60-75% by weight. More preferably, the dispersion additionally contains 5-10% by weight acetone. Furthermore, the dispersion may also contain a proportion, preferably less than 5%, of 1-methoxy-2-propanol.

[0092] The disperse phase preferably consists of finely distributed solid particles. Such particles are preferably in the form of pigments, especially color pigments. The pigments are preferably those used in inks, especially in inkjet inks, and contribute to the coloring. For example, carbon black particles are used as pigments. Carbon black 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.

[0093] The dispersion is more preferably an ink, in particular an inkjet ink. Inkjet inks in particular have a high proportion of highly volatile solvent and / or highly volatile solvents. Such inks mainly use highly volatile ketones as solvents. Furthermore, solid pigments are 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. Such an ink also contains solid particles. These are often color-imparting pigments, such as carbon black in black ink. Such inks, in particular inkjet inks, are particularly suitable as dressing agents. After the solvents have evaporated, the solids remain. These solids then form a layer thickness that can be used for dressing. The layer thickness is preferably between 2 micrometers and 15 micrometers.This layer is scratch-resistant, heat-resistant, and pressure-resistant. The layer is preferably approximately 4-5 micrometers thick with each application. By applying multiple layers, a final thickness of between 4 and 15 micrometers can easily be achieved.

[0094] 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 within a short time, leaving a layer with a thickness of 1 mm. This takes place 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 process particularly easy. All that is required is an inkjet printing system to be arranged over the support surface 358 without major adjustments, and dressing can be carried out 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 include a continuous inkjet print head or have droplet-by-drop ejection. The inkjet head can be manually controlled and guided to the desired position, or it can be integrated into the PLC control system of the punching machine via a fully automated xy axis with a rotating head. The operator would mark the positions to be adjusted on the control station. The print head can then be moved over the corresponding area. List of reference symbols
