Furthermore, the method comprises treating at least one area extending along the printing direction between the first partial structure of the printing pattern and the second partial structure of the printing pattern by irradiating this area with electromagnetic waves and/or sound waves, so that the two spatially separated partial structures of the printing pattern be merged.

  • the treated area between the first substructure and the second substructure can of course also contain adjacent edge regions of the two substructures. This fact is reflected in the fact that we talk about treating at least the area between the substructures.

  • Irradiating the treatment area i.e. an area of the surface in which two partial structures are arranged next to one another, with electromagnetic radiation and/or sound waves results in the viscosity of the paint being reduced in this area.
  • This change in the viscosity of the paint is preferably local and temporary.

  • the method can, for example, be set up in such a way that the area irradiated by a corresponding radiation source within the treatment area follows the current printing area.

Description

Die vorliegende Erfindung betrifft ein Verfahren zum Bedrucken einer Oberfläche mit einem Druckmuster, insbesondere zum Bedrucken einer Fahrzeugkarosserie, wobei beim Druckvorgang eine Glättung der Bereiche zwischen Teilstrukturen des Druckmusters vorgenommen wird.The present invention relates to a method for printing a surface with a print pattern, in particular for printing a vehicle body, wherein the areas between partial structures of the print pattern are smoothed during the printing process.

Es ist eine Technologie bekannt, die ähnlich wie ein konventioneller Drucker, gemäß welcher ein Muster auf eine Karosserie gedruckt werden kann, wobei es sich bei dem Muster etwa um Rallyestreifen handeln kann. Hierbei sei beispielhaft auf Druckschrift DE 10 2014 221 103 A1 verwiesen, in der ein Verfahren zum mehrbahnigen Bedrucken von Automobilkarosserien offenbart ist. Bei Druckvorgängen dieser Art werden aufgrund der Form des Druckkopfes zu druckende flächige Muster in einzelnen Lackstreifen hinter- bzw. unter- oder übereinander gedruckt, ähnlich wie es bei einem gewöhnlichen Tintenstrahldrucker der Fall ist. Der Abstand zwischen den einzelnen Bahnen wird dabei derart gewählt, dass der Lack zwischen den Bahnen so verläuft, dass anschließend nach Aushärtung/Trocknung des Lacks eine geschlossene Farbfläche entsteht. Leider gestaltet sich das Auffinden optimaler Abstände zwischen den Streifen relativ schwierig, da das Fließverhalten des Lacks von vielen Parametern abhängig ist. Ein nicht optimal eingestellter Abstand zwischen den gedruckten Streifen kann dazu führen, dass die einzelnen Bahnen untereinander nicht geschlossen werden und/oder zu stark zerlaufen und es zur Bildung von Überlappbereichen kommt. Beide Effekte wirken sich negativ auf die Qualität des gedruckten Musters aus und sind daher zu vermeiden.A technology is known, similar to a conventional printer, according to which a pattern can be printed on a car body, the pattern being, for example, rally stripes. An example of this is printed matter DE 10 2014 221 103 A1 referred to, in which a method for multi-lane printing of automobile bodies is disclosed. In printing processes of this type, due to the shape of the print head, flat patterns to be printed are printed in individual strips of varnish behind, below or above one another, similar to what is the case with a normal inkjet printer. The distance between the individual strips is chosen in such a way that the paint runs between the strips in such a way that a closed colored area is created after the paint has hardened/dryed. Unfortunately, finding optimal distances between the stripes is relatively difficult because the flow behavior of the paint depends on many parameters. If the distance between the printed strips is not optimally set, this can result in the individual webs not being closed with each other and/or spreading too much and overlapping areas forming. Both effects have a negative impact on the quality of the printed pattern and should therefore be avoided.

B. der Glättung aufgetragener Beschichtungsfilme. Druckschrift DE 10 2012 208 487 A1 stellt Verfahren und Systeme bereit, in denen eine Phasenänderungsgeltinte unter Anwendung von Ultraschallenergie vor dem endgültigen Aushärten der Phasenänderungsgeltinte eingeebnet wird.Pamphlet DE 10 2007 034 877 A1 discloses a device and a method for applying coatings, and in particular devices and measures for specifically influencing the surface structure of the still fluid film, such as. B. smoothing applied coating films. Pamphlet DE 10 2012 208 487 A1 provides methods and systems in which a phase change gel ink is used is leveled by ultrasonic energy before the final curing of the phase change gel ink.

Ausgehend davon liegt der vorliegenden Erfindung die Aufgabe zu Grunde, ein Druckverfahren der eingangs genannten Art bereitzustellen, bei dem ein optimales Druckergebnis erreicht werden kann.Based on this, the present invention is based on the object of providing a printing method of the type mentioned at the outset in which an optimal printing result can be achieved.

Eine Lösung hierfür wird durch ein Verfahren zum Bedrucken einer Oberfläche gemäß dem unabhängigen Patentanspruch bereitgestellt. Weitere Ausgestaltungen ergeben sich aus den abhängigen Patentansprüchen und der beiliegenden Beschreibung.A solution to this is provided by a method for printing a surface according to the independent claim. Further refinements result from the dependent patent claims and the accompanying description.

Erfindungsgemäß weist das Verfahren zum Bedrucken einer Oberfläche mit einem Druckmuster Drucken einer ersten Teilstruktur des Druckmusters und Drucken einer zweiten Teilstruktur des Druckmusters nach dem Drucken der ersten Teilstruktur des Druckmusters in einem Abstand zu der ersten gedruckten Teilstruktur auf, so dass die beiden Teilstrukturen räumlich voneinander getrennt sind. Ferner weist das Verfahren Behandeln mindestens eines sich entlang der Druckrichtung erstreckenden Bereiches zwischen der ersten Teilstruktur des Druckmusters und der zweiten Teilstruktur des Druckmuster auf, indem dieser Bereich mit elektromagnetischen Wellen und/oder Schallwellen bestrahlt wird, so dass die zwei räumlich voneinander getrennten Teilstrukturen des Druckmusters zusammengeführt werden.According to the invention, the method for printing a surface with a print pattern includes printing a first partial structure of the printing pattern and printing a second partial structure of the printing pattern after printing the first partial structure of the printing pattern at a distance from the first printed partial structure, so that the two partial structures are spatially separated from one another are. Furthermore, the method comprises treating at least one area extending along the printing direction between the first partial structure of the printing pattern and the second partial structure of the printing pattern by irradiating this area with electromagnetic waves and/or sound waves, so that the two spatially separated partial structures of the printing pattern be merged.

Das erfindungsgemäße Verfahren kann insbesondere eingesetzt werden, um Lack auf Karosserieteile von Fahrzeugen, etwa Motorhauben oder Türen, anzubringen und so Druckmuster zu erzeugen. Das zu druckende Muster wird dabei in Teilstrukturen sequentiell gedruckt, wobei die Teilstrukturen eine nach der anderen in einem Abstand zueinander gedruckt werden. Der Abstand kann einige wenige Millimeter betragen. Ein bündiges Aneinanderreihen der Teilstrukturen wird nicht vorgenommen, da es dann meist zu den bereits erwähnten sichtbaren Überlagerungen des Lacks kommt und die Übergänge zwischen den Streifen somit nicht homogen sind. Bei dem erfindungsgemäßen Verfahren wird mindestens der Bereich zwischen der ersten Teilstruktur und der zweiten Teilstruktur nachbehandelt, indem er elektromagnetischer Strahlung und/oder Schallwellen ausgesetzt wird. Hierbei kann der behandelte Bereich zwischen der ersten Teilstruktur und der zweiten Teilstruktur selbstverständlich auch daran anliegende Randbereiche der beiden Teilstrukturen enthalten. Diese Tatsache spiegelt sich darin wieder, dass von der Behandlung mindestens des Bereiches zwischen den Teilstrukturen gesprochen wird. Mit anderen Worten ist bei dem Verfahren nicht beabsichtigt, ausschließlich den zwischen den gedruckten Teilstrukturen liegenden Bereich der Oberfläche zu behandeln, sondern auch die an diesen lackfreien Bereich anliegenden Randbereiche der Teilstrukturen. Aufgrund der üblicherweise kleinen räumlichen Abstände zwischen den gedruckten Teilstrukturen kann auch davon gesprochen werden, dass im Rahmen des erfindungsgemäßen Verfahrens die Naht zwischen einzelnen Druckbahnen behandelt wird.The method according to the invention can be used in particular to apply paint to body parts of vehicles, such as hoods or doors, and thus produce printed patterns. The pattern to be printed is printed sequentially in sub-structures, with the sub-structures being printed one after the other at a distance from one another. The distance can be a few millimeters. The partial structures are not aligned flush, as this usually results in the already mentioned visible overlays of the paint and the transitions between the stripes are therefore not homogeneous. In which According to the method according to the invention, at least the area between the first substructure and the second substructure is post-treated by exposing it to electromagnetic radiation and / or sound waves. Here, the treated area between the first substructure and the second substructure can of course also contain adjacent edge regions of the two substructures. This fact is reflected in the fact that we talk about treating at least the area between the substructures. In other words, the method is not intended to treat exclusively the area of the surface lying between the printed partial structures, but also the edge areas of the partial structures adjacent to this paint-free area. Due to the usually small spatial distances between the printed partial structures, it can also be said that the seam between individual printing webs is treated as part of the method according to the invention.

Das Bestrahlen des Behandlungsbereiches, also eines Bereiches der Oberfläche, in dem zwei Teilstrukturen nebeneinander angeordnet sind, mit elektromagnetischer Strahlung und/oder mit Schallwellen führt dazu, dass in diesem Bereich die Viskosität des Lacks erniedrigt wird. Diese Veränderung der Viskosität des Lacks ist bevorzugt lokal und temporär. Die Veränderung der Viskosität des Lacks geht mit einer Anpassung des Fließverhaltens des Lacks in dem Behandlungsbereich einher und kann insbesondere bewirken, dass der Lack entlang der Ränder von zwei durch eine Lücke getrennten Teilstrukturen zerläuft bzw. besser zerläuft und die Lücke so geschlossen wird. Anders ausgedrückt kann die Nachbehandlung mit elektromagnetischer und/oder akustischer Strahlung bewirken, dass zwei räumlich getrennte Teilstrukturen des Druckmusters entlang ihrer aneinander angrenzenden Ränder zusammengeführt werden. Das Fließverhalten des Lacks des gedruckten Musters kann dabei so gewählt werden, dass der Lack im Randbereich der Teilstrukturen ohne die Behandlung kaum oder gar nicht zerfließen würde und folglich die räumliche Trennung aufrecht erhalten werden würde. Insbesondere kann die Viskosität des verwendeten Lacks so gewählt werden, dass der Lack auf unebenen und/oder schräg gestellten Oberflächen gedruckt werden kann und dabei nicht von selbst zerfließt. Erst durch die lokale und temporäre Nachbehandlung mittels elektromagnetischen und/oder akustischen Wellen wird ein "Aufweichen" der Ränder der gedruckten Teilstrukturen herbeigeführt, was zum Schließen der Nahtstellen führt und ein gleichmäßiges Druckmuster ergibt.Irradiating the treatment area, i.e. an area of the surface in which two partial structures are arranged next to one another, with electromagnetic radiation and/or sound waves results in the viscosity of the paint being reduced in this area. This change in the viscosity of the paint is preferably local and temporary. The change in the viscosity of the paint is accompanied by an adjustment of the flow behavior of the paint in the treatment area and can in particular cause the paint to melt or to melt better along the edges of two partial structures separated by a gap and the gap is thus closed. In other words, the post-treatment with electromagnetic and/or acoustic radiation can cause two spatially separate partial structures of the print pattern to be brought together along their adjacent edges. The flow behavior of the varnish of the printed pattern can be chosen so that the varnish in the edge area of the partial structures would hardly or not flow at all without the treatment and consequently the spatial separation would be maintained. In particular, the viscosity of the paint used can be chosen so that Varnish can be printed on uneven and/or slanted surfaces and does not flow away on its own. Only through the local and temporary post-treatment using electromagnetic and/or acoustic waves is the edges of the printed partial structures “softened”, which leads to the closing of the seams and results in a uniform printing pattern.

Ferner können im Rahmen des hier beschriebenen Verfahrens Lacke verwendet werden, welche keine Lösemittel aufweisen, um ein leichtes Zerfließen des Lacks herbeizuführen, nachdem auf die Oberfläche appliziert worden ist.Furthermore, as part of the method described here, paints can be used which do not contain any solvents in order to cause the paint to flow easily after it has been applied to the surface.

Gemäß weiteren Ausführungsformen des Verfahrens kann das Behandeln des mindestens einen Bereiches zeitgleich mit dem Druckvorgang bzw. währenddessen erfolgen. Dabei kann der bestrahlte Bereich unmittelbar an den aktuellen Druckbereich angrenzen oder es kann zwischen den beiden Stellen ein Abstand vorliegen, welcher von zahlreichen Parametern wie Druckgeschwindigkeit, Lackdicke, Lacktrocknungszeit usw. abhängig sein und geeignet eingestellt werden kann. Unter dem aktuellen Druckbereich kann ein Bereich der Oberfläche verstanden werden, an dem zu dem betrachteten Zeitpunkt mittels eines Druckkopfes Lack auf die Oberfläche aufgebracht wird. Das Verfahren kann beispielsweise so eingerichtet sein, dass die durch eine entsprechende Strahlungsquelle bestrahlte Fläche innerhalb des Behandlungsbereiches dem aktuellen Druckbereich nachgeführt wird. So kann ein zwischen zwei Teilstrukturen liegender lackfreier Bereich samt angrenzenden Lackrändern behandelt werden, sobald die zweite Teilstruktur bzw. zweite Bahn von dem Druckkopf appliziert worden ist. Die bestrahlte Fläche innerhalb des Behandlungsbereiches kann dem aktuellen Druckbereich gleitend nachgeführt werden. Hierzu kann beispielsweise die entsprechende elektromagnetische und/oder akustische Strahlungsquelle einem Druckkopf eines Druckers nachgeführt werden.According to further embodiments of the method, the treatment of the at least one area can take place at the same time as the printing process or during it. The irradiated area can be directly adjacent to the current printing area or there can be a distance between the two locations, which depends on numerous parameters such as printing speed, paint thickness, paint drying time, etc. and can be suitably adjusted. The current printing area can be understood to be an area of the surface to which paint is applied to the surface by means of a print head at the time in question. The method can, for example, be set up in such a way that the area irradiated by a corresponding radiation source within the treatment area follows the current printing area. For example, a paint-free area between two partial structures can be treated, including adjacent paint edges, as soon as the second partial structure or second web has been applied by the print head. The irradiated area within the treatment area can be smoothly guided along the current printing area. For this purpose, for example, the corresponding electromagnetic and/or acoustic radiation source can be guided along a print head of a printer.

Gemäß weiteren Ausführungsformen des Verfahrens können die die elektromagnetischen Wellen im UV-Bereich und/oder IR-Bereich liegen. Die Bestrahlung mit elektromagnetischen Wellen kann allgemein zu einer thermischen bzw. optischen Anregung des Lacks führen. Die Bestrahlung mit Schallwellen kann als eine mechanische Anregung des Lacks im Behandlungsbereich aufgefasst werden und in etwa mit dem Effekt einer mikroskopischen Rüttelplatte veranschaulicht werden.According to further embodiments of the method, the electromagnetic waves can be in the UV range and/or IR range. Irradiation with electromagnetic waves can generally be thermal or optical Lead to stimulation of the paint. The irradiation with sound waves can be seen as a mechanical stimulation of the paint in the treatment area and can be illustrated roughly with the effect of a microscopic vibrating plate.

Gemäß weiteren Ausführungsformen des Verfahrens kann der Lack, mittels welchem das Druckmuster gebildet wird, mindestens erste Farbpartikel bzw. und Additiv-Partikel aufweisen. Die Farbpartikel können für die Farbe des Lacks bestimmen. Die Wellenlänge der elektromagnetischen Wellen kann so gewählt werden, dass die Farbpartikel und/oder die Additiv-Partikel angeregt werden. Bei der Anregung mittels elektromagnetischer Strahlung kann es sich um eine optische bzw. eine thermische Anregung der Partikel und/oder der Additiv-Partikel handeln. Bei den Additiv-Partikeln kann es sich um Zusatzpartikel handeln, welche insbesondere für einen guten Energieeintrag in den Lack zu diesem hinzugefügt werden. Anders ausgedrückt können die Additiv-Partikel im Lack mittels auf diese abgestimmter elektromagnetischer Strahlung bestrahlt werden und so der Lack insgesamt erwärmt werden.According to further embodiments of the method, the lacquer by means of which the print pattern is formed can have at least first color particles or additive particles. The color particles can determine the color of the paint. The wavelength of the electromagnetic waves can be chosen so that the color particles and/or the additive particles are excited. The excitation by means of electromagnetic radiation can involve optical or thermal excitation of the particles and/or the additive particles. The additive particles can be additional particles which are added to the paint in particular to ensure good energy input into the paint. In other words, the additive particles in the paint can be irradiated using electromagnetic radiation tailored to them and the paint as a whole can be heated.

Gemäß weiteren Ausführungsformen des Verfahrens kann es sich bei der ersten Teilstruktur und bei der zweiten Teilstruktur jeweils um einen Streifen handeln. Die Streifen können in Bahnen gedruckt werden, wobei eine Druckbahn einem Streifen entsprechen kann. Durch Aufdrucken einer Vielzahl von dicht aneinander angeordneten Streifen können ihre Nahtbereiche mittels der Nachbehandlung zusammengeführt werden und so beliebige größere Druckmuster erzeugt werden.According to further embodiments of the method, the first substructure and the second substructure can each be a strip. The strips can be printed in strips, whereby a printing strip can correspond to a strip. By printing a large number of strips arranged close together, their seam areas can be brought together by means of post-treatment and any larger print patterns can be created.

Zum Durchführen des erfindungsgemäßen Druckverfahrens kann eine Vorrichtung zum Bedrucken einer Oberfläche mit einem Druckmuster verwendet werden, wobei die Vorrichtung einen Druckkopf und einen Applikationskopf aufweist, welcher eine erste Abstrahlvorrichtung und eine zweite Abstrahlvorrichtung aufweist, wobei die erste Abstrahlvorrichtung zur Abstrahlung elektromagnetischer Wellen eingerichtet ist und die zweite Abstrahlvorrichtung zur Abstrahlung von Schallwellen eingerichtet ist, wobei der Applikationskopf an dem Druckkopf angeordnet ist.To carry out the printing method according to the invention, a device for printing a surface with a print pattern can be used, the device having a print head and an application head, which has a first emitting device and a second emitting device, the first emitting device being set up to emit electromagnetic waves and the second radiation device is set up to emit sound waves, the application head being arranged on the print head.

Der Applikationskopf kann beispielsweise derart seitlich am Druckkopf angeordnet sein, dass damit während eines stattfindenden Druckvorgangs ein dicht hinter dem aktuellen Druckbereich liegender Bereich bestrahlt wird. Ebenso kann der Applikationskopf in einem Abstand zu Druckkopf an diesen befestigt sein, so dass seine Bewegungsbahn an die Bewegungsbahn des Druckkopfes gekoppelt ist.The application head can, for example, be arranged laterally on the print head in such a way that an area lying close behind the current printing area is irradiated during a printing process that is taking place. Likewise, the application head can be attached to the print head at a distance from the print head, so that its movement path is coupled to the movement path of the print head.

Es versteht sich, dass die voranstehend genannten und die nachstehend noch zu erläuternden Merkmale nicht nur in der jeweils angegebenen Kombination, sondern auch in anderen Kombinationen verwendbar sind, ohne den Rahmen der vorliegenden Erfindung zu verlassen, der in den Ansprüchen definiert ist.It is understood that the features mentioned above and those to be explained below can be used not only in the combination specified in each case, but also in other combinations, without departing from the scope of the present invention, which is defined in the claims.

Weitere Vorteile und Ausgestaltungen der Erfindung ergeben sich aus der Beschreibung und den beiliegenden Zeichnungen. Dabei zeigt

  • Figur 1 eine schematische Darstellung eins aus einzelnen Teilstrukturen aufgebautes Druckmuster.
  • Figur 2 eine schematische Darstellung eins beispielhaften Druckvorgangs gemäß der Erfindung.
Further advantages and refinements of the invention result from the description and the accompanying drawings. This shows
  • Figure 1 a schematic representation of a print pattern made up of individual substructures.
  • Figure 2 a schematic representation of an exemplary printing process according to the invention.

In Figur 1 ist ein Bauteil 1 gezeigt, auf dem ein schematisches Druckmuster 2 angeordnet ist. Das Druckmuster 2 weist einzelne Teilstrukturen in Form von Druckstreifen 3 auf,' welche dicht nebeneinander angeordnet sind. Zwischen 'den Druckstreifen 3 sind Freiräume angeordnet, welche verdeutlichen sollen, dass die Druckstreifen 3 beim Drucken nicht bündig aneinander, sondern in kleinen Abständen zueinander gedruckt werden. Üblicherweise wird versucht die Viskosität des Lacks so zu wählen, dass der Lack an den Rändern der Druckstreifen ein wenig zerläuft bzw. zerfließt und dadurch die Freiräume geschlossen werden.In Figure 1 a component 1 is shown, on which a schematic print pattern 2 is arranged. The print pattern 2 has individual partial structures in the form of print strips 3, which are arranged close to one another. Free spaces are arranged between the printing strips 3, which are intended to make it clear that the printing strips 3 are not printed flush with one another during printing, but rather at small distances from one another. Usually, an attempt is made to choose the viscosity of the varnish so that the varnish runs or flows a little at the edges of the print strips, thereby closing the free spaces.

In Figur 2 ist ein Ausführungsbeispiel des erfindungsgemäßen Druckverfahrens auf Basis des in Figur 1 gezeigten Druckmusters 2 veranschaulicht. Die einzelnen Druckstreifen 3 werden mittels eines Druckkopfes 4 gedruckt, welcher hier eine beispielhaft rechteckige Form aufweist. Der Druckkopf 4 wird hierbei von links nach rechts bewegt (Druckrichtung ist mittels Pfeil 5 angedeutet) und appliziert die Druckstreifen 3 der Reihe nach von unten nach oben. Zwischen dem obersten und dem darunter angeordneten Druckstreifen 3 ist ein Behandlungsbereich 7 dargestellt, welcher mindestens den Bereich zwischen den beiden Druckstreifen 3 aufweist und auch Randbereiche der beiden Druckstreifen 3 enthält. Der Behandlungsbereich 7 kann beispielsweise zweckmäßigerweise beim Drucken des obersten Druckstreifens 3 behandelt werden mittels eines Applikationskopfes 6, welcher bezüglich der Bewegungsrichtung 5 des Druckkopfes 3 dahinter angeordnet ist und beim Drucken mitgeführt wird. Folglich erfolgt die Behandlung im Behandlungsbereich 7 stückweise gleitend von einer Seite zur anderen Seite des Behandlungsbereiches 7. Anders ausgedrückt kann, sobald eine zweite Lackbahn von dem Druckkopf 4 appliziert wird mittels des Applikationskopfes 6 die Naht zwischen den Bahnen behandelt werden, so dass der Lack im Behandlungsbereich 7 besser verlaufen kann.In Figure 2 is an exemplary embodiment of the printing method according to the invention based on of the in Figure 1 shown print pattern 2 illustrated. The individual print strips 3 are printed using a print head 4, which here has an example rectangular shape. The print head 4 is moved from left to right (printing direction is indicated by arrow 5) and applies the print strips 3 in sequence from bottom to top. A treatment area 7 is shown between the topmost and the print strip 3 arranged below it, which has at least the area between the two print strips 3 and also contains edge areas of the two print strips 3. The treatment area 7 can, for example, expediently be treated when printing the top print strip 3 by means of an application head 6, which is arranged behind it with respect to the direction of movement 5 of the print head 3 and is carried along during printing. Consequently, the treatment in the treatment area 7 takes place piece by piece, sliding from one side to the other side of the treatment area 7. In other words, as soon as a second lacquer web is applied by the print head 4, the seam between the webs can be treated by means of the application head 6, so that the lacquer in the Treatment area 7 can go better.

Zur Veranschaulichung des Funktionsprinzips des erfindungsgemäßen Verfahrens sind die untersten drei Druckstreifen in Figur 2 in einem Abstand zueinander angeordnet, obwohl die Freiräume zwischen diesen drei Druckstreifen 3 geschlossen bzw. mit Lack bedeckt sind, da entsprechenden Behandlungsbereiche bereits mit elektromagnetischer Strahlung und/oder mit Ultraschall bestrahlt worden sind.To illustrate the functional principle of the method according to the invention, the bottom three print strips are in Figure 2 arranged at a distance from one another, although the free spaces between these three printing strips 3 are closed or covered with varnish, since corresponding treatment areas have already been irradiated with electromagnetic radiation and / or ultrasound.
