Description

Die Erfindung betrifft eine Druckvorrichtung zum Bedrucken von Druckgütern gemäß dem Anspruch 1 sowie ein Verfahren zum Bedrucken von Druckgütern gemäß dem Anspruch 4.The invention relates to a printing device for printing printed matter according to claim 1 and a method for printing printed matter according to claim 4.

In der Drucktechnik ist eine der druckdurchsatz-limitierenden Faktoren die Geschwindigkeit, mit welcher ein Druckbild auf dem zu bedruckenden Druckgut vorsehbar ist. Insbesondere bei der Nassdrucktechnik, also bei der Verwendung von viskoser Druckerfarbe werden verfahrbare Druckeinrichtungen verwendet, welche einem Druckgut in einem zu bedruckenden Bereich zustellbar sind. Die Geschwindigkeit, mit welcher eine solche Druckeinrichtung seine Position in einem Druckbereich zwischen Applikationspunkten verändern kann ist mechanischen Grenzen unterworfen. Auch kann ein zu geringer zeitlicher Abstand zwischen einem Positionswechsel einer Druckeinrichtung und der anschließenden Auftragung eines flüssigen Druckerfarbetröpfchens auf dem Druckgut dazu führen, dass beim Auftragen eines Druckerfarbetröpfchens auf das Druckgut Fliehkräfte auf das Druckerfarbetröpfchen wirken. Diese können die geometrische Form des Druckerfarbetröpfchens nachteilig beeinflussen. Somit kann ein zu geringer zeitlicher Abstand zwischen einer Neupositionierung der Druckeinheit und eines durch die Druckeinheit aufzutragenden Druckerfarbetröpfchens zu einer Unschärfe des Druckbildes führen. Aus Gründen der Effizienz einer verwendeten Druckeinrichtung sowie aus Wirtschaftlichkeitserwägungen heraus besteht das andauernde Bedürfnis an einer Vorrichtung oder einem Verfahren, welche es erlauben, die benannten und weitere Grenzen der Drucktechnik zu überwinden und eine effiziente Möglichkeit des Bedruckens bereit zu stellen.In printing technology, one of the factors that limit the printing throughput is the speed at which a print image can be provided on the item to be printed. In particular in wet printing technology, that is to say when using viscous printing ink, movable printing devices are used which can be delivered to a print item in an area to be printed. The speed at which such a printing device can change its position in a printing area between application points is subject to mechanical limits. If the time interval between a change in position of a printing device and the subsequent application of a liquid printer ink droplet to the print material is too short, centrifugal forces act on the printer ink droplet when a printer ink droplet is applied to the print material. These can adversely affect the geometric shape of the printer ink droplet. Thus, too short a time interval between a repositioning of the printing unit and a printer ink droplet to be applied by the printing unit can lead to a blurring of the print image. For reasons of the efficiency of a printing device used as well as economic considerations, there is an ongoing need for a device or a method which allows the named and other limits of printing technology to be overcome and an efficient way of printing available.

Eine gattungsgemäße Druckvorrichtung ist beispielsweise aus der CN 201941271 U bekannt. Diese betrifft einen Drucker, welcher mehrere nebeneinander angeordnete Textilien mittels eines digitalen Inkjet-Druckkopfs bedruckt. Die Druckvorrichtung umfasst zwei separate Halter für zu bedruckende Textile. Durch Verfahren des Drucckopfs entlang einer Führungsschiene, kann dieser die Textilien bedrucken.A generic printing device is for example from CN 201941271 U known. This concerns a printer which prints several textiles arranged next to one another by means of a digital inkjet print head. The printing device comprises two separate holders for textiles to be printed. By moving the print head along a guide rail, it can print on the textiles.

Die US 2009/0267975 A1 lehrt ein Verfahren und eine Vorrichtung zum Bedrucken von Displaypaneelen. Hierzu ist eine Druckvorrichtung vorgesehen, welche in Form eines Querbalkens über einem Druckbett angeordnet ist und Druckköpfe aufweist, welche über der zu bedruckenden Oberfläche angeordnet sind. Die Druckköpfe sind ausgebildet unabhängig voneinander entlang der Druckeinrichtung verfahren zu werden.The US 2009/0267975 A1 teaches a method and apparatus for printing on display panels. For this purpose, a printing device is provided which is arranged in the form of a transverse bar above a printing bed and has print heads which are arranged above the surface to be printed. The print heads are designed to be moved independently of one another along the printing device.

Aus der US 2009/0120249 A1 geht eine gattungsgemäße Vorrichtung hervor, welche zum Bearbeiten von Holzpaneelen ausgebildet ist. Die Holzpaneele werden mittels der Vorrichtung sowohl zugeschnitten als auch bedruckt. Hierfür ist an mindestens einer Portalführung ein erster Druckkopf und ein zweiter Druckkopf an gegenüberliegenden Seiten der Portalführung angeordnet, welche unabhängig voneinander entlang der Portalführung verfahrbar angeordnet sind. Die Portalführung ist gegenüber einem vorgesehenen Förderband in einer X-Richtung verfahrbar vorgesehen.From the US 2009/0120249 A1 a generic device emerges which is designed for processing wooden panels. The wooden panels are both cut and printed using the device. For this purpose, a first print head and a second print head are arranged on opposite sides of the portal guide on at least one portal guide and are arranged to be movable independently of one another along the portal guide. The portal guide is provided such that it can be moved in an X direction with respect to a conveyor belt provided.

Weiterhin liegt der Erfindung die Aufgabe zugrunde, ein Verfahren zum Bedrucken von Druckgütern anzugeben.The invention is based on the object of specifying a printing device which enables efficient printing of a material to be printed. The invention is also based on the object of specifying a method for printing printed goods.

Die Aufgabe wird nach der Erfindung durch eine Druckvorrichtung zum Bedrucken von Druckgütern mit den Merkmalen des Anspruchs 1 sowie durch ein Verfahren zum Bedrucken von Druckgütern nach Anspruch 4 gelöst. Bevorzugte Ausführungsformen sind in den jeweils abhängigen Ansprüchen angegeben.The object is achieved according to the invention by a printing device for printing printed matter having the features of claim 1 and by a method for printing printed matter according to claim 4. Preferred embodiments are specified in the respective dependent claims.

Bei der erfindungsgemäßen Druckvorrichtung zum Bedrucken von Druckgütern ist vorgesehen, dass die Druckeinrichtung mindestens eine erste Druckkopfeinheit und eine zweite Druckkopfeinheit aufweist, welche voneinander unabhängig an der Führungseinrichtung über die Breite des Maschinengrundkörpers relativ zu einander verfahrbar sind, und dass jede Druckkopfeinheit mindestens einen Druckkopf aufweist, welcher ausgebildet ist, das Druckgut mit mindestens einer Druckerfarbe zu bedrucken.In the printing device according to the invention for printing printed matter, it is provided that the printing device has at least one first print head unit and one second print head unit, which can be moved independently of one another on the guide device over the width of the machine base body relative to one another, and that each print head unit has at least one print head, which is designed to print the material to be printed with at least one printing ink.

Weiterhin ist das erfindungsgemäße Verfahren zum Bedrucken von Druckgütern dadurch gekennzeichnet, dass eine erste Druckkopfeinheit und mindestens eine zweite Druckkopfeinheit der Druckeinrichtung, voneinander unabhängig über die Breite des Haltegrundkörpers relativ zueinander entlang einer Führungseinrichtung verfahren werden und dass mindestens eine Druckgut mit einem Druckbild bedrucken.Furthermore, the method according to the invention for printing printed matter is characterized in that a first printhead unit and at least one second printhead unit of the printing device are moved independently of one another over the width of the support base relative to one another along a guide device and that at least one printed matter is printed with a print image.

Ein Grundgedanke der Erfindung besteht darin, eine Druckvorrichtung mit einer mehrteiligen Druckeinrichtung bereit zu stellen, wobei die einzelnen Teile der Druckeinrichtung mindestens einem Druckbereich auf dem Druckgut oder den Druckgütern individuell beziehungsweise unabhängig voneinander zustellbar sind.A basic idea of the invention is to provide a printing device with a multi-part printing device, the individual parts of the printing device being able to be delivered to at least one printing area on the print item or items individually or independently of one another.

Weiterhin besteht ein Grundgedanke der Erfindung darin, ein Verfahren zum Bedrucken eines Druckgutes anzugeben, bei welchem mehrere Teile einer Druckeinrichtung individuell beziehungsweise unabhängig voneinander dem zu bedruckenden Druckgut oder Druckgütern zugestellt werden.Furthermore, a basic concept of the invention consists in specifying a method for printing a print item, in which several parts of a printing device are delivered individually or independently of one another to the print item or items to be printed.

Individuell zustellbar kann in diesem Zusammenhang insbesondere bedeuten, dass Teile der Druckeinrichtung einzeln ansteuerbar sind, um eine Position beispielsweise gegenüber dem Maschinengrundkörper der Druckvorrichtung, insbesondere an der Führungseinrichtung, einzunehmen. "Unabhängig voneinander" kann in diesem Zusammenhang insbesondere bedeuten, dass die Position beziehungsweise Bewegung eines Teils der Druckeinrichtung keine einschränkende Wirkung auf eine Wahl der Position eines weiteren Teils der Druckeinrichtung beziehungsweise auf dessen Bewegungsabläufe und -spielräume, insbesondere entlang der Führungseinrichtung, hat.In this context, individually deliverable can in particular mean that parts of the printing device can be controlled individually in order to assume a position, for example, with respect to the machine base body of the printing device, in particular on the guide device. In this context, “independently of one another” can in particular mean that the position or movement of a part of the printing device has no restrictive effect on a selection of the position of a further part of the printing device or on its movement sequences and latitude, in particular along the guide device.

Das Druckgut kann jedes beliebige zu bedruckende Objekt sein. Bevorzugterweise weist das Druckgut mindestens in einem Druckbereich eine ebene, insbesondere zum Maschinengrundkörper parallel ausgerichtete Oberfläche auf. Besonders bevorzugt handelt es sich bei dem Druckgut um textile Materialien.The print material can be any object to be printed.

Der Maschinengrundkörper kann grundsätzlich jede Form aufweisen, die das Aufnehmen und Halten der einzelnen Einrichtungen der Druckvorrichtung ermöglicht. Besonders zweckmäßig ist eine rechteckige Form des Maschinengrundkörpers. Die Translationseinrichtung kann ausgebildet sein, grundsätzlich mindestens ein Druckgut aufzunehmen, wobei die Position der Translationseinrichtung auf dem Maschinenstrukturkörper und folglich die Position des mindestens einen Druckguts auf der Druckvorrichtung, insbesondere dem Maschinengrundkörper, veränderbar sein kann.According to the invention, it is provided that the machine base has at least one translation device on which the received print item is arranged and which is designed to change the position of the at least one print item relative to the machine base body. The machine base body can in principle have any shape that enables the individual devices of the printing device to be picked up and held. A rectangular shape of the machine base is particularly useful. The translation device can be designed to basically receive at least one print item, wherein the position of the translation device on the machine structural body and consequently the position of the at least one print item on the printing device, in particular the machine base, can be changed.

Somit kann grundsätzlich eine Zustellung der mindestens einen Druckkopfeinheit zu einem Druckbereich auf dem Druckgut durch Verfahren und/oder durch Positionieren der Druckkopfeinheit in einem Bereich oberhalb des Maschinengrundkörpers, oder durch Verfahren und/oder Positionieren des mindestens einen Druckguts auf dem Maschinengrundkörper auf der Translationseinrichtung ermöglicht sein. Ebenso ist eine Kombination von beidem denkbar, wobei Druckgut durch die Translationseinrichtung und die mindestens eine Druckkopfeinheit, insbesondere an der Führungseinrichtung, verfahrbar ist, um mittels beispielsweise anteiliger Relativverschiebung beider die mindestens eine Druckkopfeinheit einem zu bedruckenden Bereich auf dem Druckgut zuzustellen.Thus, in principle, the at least one print head unit can be delivered to a print area on the print material by moving and / or by positioning the print head unit in an area above the machine base body, or be made possible by moving and / or positioning the at least one print item on the machine base body on the translation device. A combination of both is also conceivable, whereby the print material can be moved by the translation device and the at least one print head unit, in particular on the guide device, in order to deliver the at least one print head unit to an area to be printed on the print material by means of, for example, a proportional relative displacement of the two.

Demnach kann die Relativverschiebung von Druckgut und Druckkopfeinheit beziehungsweise Druckkopfeinheiten sowohl durch ausschließliches als auch anteiliges Verfahren von mindestens einem der Translationseinrichtung und/oder der Drucckopfeinheit(en), also einer oder mehrere Druckkopfeinheiten, bereitgestellt werden. Insbesondere wenn die Relativverschiebung von Translationseinrichtung beziehungsweise von Druckgut und Druckeinrichtung zueinander durch mehr als eine der beiden Einrichtungen erfolgt, kann die Distanz zwischen zwei zu bedruckenden Bereichen auf dem mindestens einen Druckgut mit einer gesteigerten Geschwindigkeit überwunden werden. Diese kann höher sein als die Bewegungsgeschwindigkeit einer einzelnen der Einrichtungen, ohne hierzu die Bewegungsgeschwindigkeit der einzelnen Einrichtungen verändern zu müssen. Druckgut beziehungsweise Druckkopfeinheit(en) sind sich somit gegenläufig und/oder wechselseitig zustellbar.Accordingly, the relative displacement of print material and printhead unit or printhead units can be provided by both exclusive and partial methods of at least one of the translation device and / or the printhead unit (s), i.e. one or more printhead units. In particular, if the relative displacement of the translation device or of the printed matter and the printing device to one another is carried out by more than one of the two devices, the distance between two areas to be printed on the at least one printed matter can be overcome at an increased speed. This can be higher than the speed of movement of an individual device without having to change the speed of movement of the individual devices. Print material or print head unit (s) can thus be delivered in opposite directions and / or reciprocally.

Eine Ausbildung der Erfindung besteht darin, dass die Translationseinrichtung mindestens zwei Schlitten aufweist, auf welchen jeweils mindestens ein Druckgut in etwa parallel zu der Längsseite des Maschinengrundkörpers verfahrbar gelagert ist. Der Schlitten kann einem beliebigen, jedoch zumindest den für den Druckvorgang relevanten Bereich(en) auf dem Maschinengrundkörper zugestellt werden. Für den Druckvorgang relevante Bereiche auf dem Maschinengrundkörper sind zumindest solche, welchen Druckkopfeinheit(en) zustellbar sind, um zu mindestens einen zu bedruckenden Bereich auf dem Druckgut auf der Translationseinheit zu bedrucken. Grundsätzlich kann das Druckgut auf dem Schlitten so befestigt sein, dass ein Verschieben oder Verrutschen auf dem Schlitten verhindert ist, was dazu beitragen kann, eine punktgenaue Positionierung der Druckeinrichtung beziehungsweise der Druckköpfe der Druckkopfeinheiten gegenüber dem zu bedruckenden Druckgut zu ermöglichen.One embodiment of the invention consists in that the translation device has at least two carriages, on each of which at least one print item is mounted so as to be movable approximately parallel to the longitudinal side of the machine base. The carriage can be delivered to any area (s) on the machine base body, but at least to the area (s) relevant for the printing process. Areas on the machine base body that are relevant for the printing process are at least those to which print head unit (s) can be delivered in order to print on the translation unit for at least one area to be printed on the print material. Basically, the print material can be attached to the carriage in such a way that it is prevented from shifting or slipping on the carriage, which can help enable the printing device or the print heads of the print head units to be positioned with pinpoint accuracy relative to the print material to be printed.

Die Translationseinrichtung kann sowohl für ein batchweises Bedrucken als auch in einem Endlosdruckverfahren eingesetzt werden. Der batchweise Betrieb kann sich insbesondere dadurch auszeichnen, dass ein diskontinuierlicher Betrieb der Druckvorrichtung durchgeführt wird, bei welchem die Translationseinrichtung in eine Ausgangsposition verfahren werden kann um ein bedrucktes Druckgut gegen ein zu bedruckendes Druckgut auszutauschen. Hierbei kann insbesondere ein Bedrucken zwischen dem Entfernen des bedruckten Druckguts von der Translationseinheit und dem Befestigen des zu bedruckenden Druckguts auf der Translationseinrichtung unterbrochen sein. Ein kontinuierlicher Betrieb der Druckvorrichtung kann insbesondere dadurch gekennzeichnet sein, dass der Druckvorrichtung mit beispielsweiser konstanter aber auch mit variabler Geschwindigkeit zu bedruckendes Druckgut in einem ersten Bereich zugestellt wird, wobei bedrucktes Druckgut in mindestens einem zweiten Bereich der Druckvorrichtung kontinuierlich abgeführt werden kann, ohne einen Druckprozess beziehungsweise den Fluss von Druckgütern vor, in oder hinter der Druckvorrichtung zu unterbrechen oder zu behindern. Hierbei kann es sich insbesondere um eine Druckvorrichtung handeln, welche einem Fließprozess beispielsweise bei der Fertigung eines zu bedruckenden Druckguts mit beispielsweise einer Konfektionierungsvorrichtung zum Konfektionieren von Kleidung vorgesehen ist.The translation device can be used both for batch printing and in a continuous printing process. The batch-wise operation can be characterized in particular by the fact that the printing device is operated discontinuously, in which the translation device can be moved into a starting position in order to exchange a printed item for a printed item to be printed. In particular, printing can be interrupted between the removal of the printed matter from the translation unit and the fastening of the printed matter to be printed on the translation device. Continuous operation of the printing device can in particular be characterized in that the printing device is fed to the printing device with, for example, constant but also variable speed print material to be printed in a first area, wherein printed print material can be continuously removed in at least a second area of the printing device without a printing process or to interrupt or hinder the flow of printed matter in front of, in or behind the printing device. This can in particular be a printing device which is provided for a flow process, for example in the production of a printed matter to be printed with, for example, a finishing device for making clothes.

Eine Ausführung der Erfindung besteht darin, dass die Führungseinrichtung in etwa parallel zu der Breitseite des Maschinengrundkörpers angeordnet ist. An der Führungseinrichtung kann die Druckeinrichtung Druck relevanten Bereichen auf dem Maschinengrundkörper zustellbar sein. Insbesondere nach dem Inkjet-Verfahren kann ein Druckbild in einem Druckbereich in zueinander parallelen Druckzeilen unterteilt sein, welche gemeinsam das Druckbild abbilden. Die Ausrichtung der Führungseinrichtung am Maschinengrundkörper kann insbesondere nach den Druckzeilen des nach beispielsweise dem Inkjet-Verfahren zu druckenden Druckbildes auf dem Druckgut erfolgen, insbesondere parallel zu den Druckzeilen sein. Somit kann durch eine Bewegung von Druckkopfeinheiten entlang der Führungseinrichtung jeweils bedarfsgerecht eine Druckzeile des auf dem Druckgut zu druckenden Druckbildes abgedruckt werden.One embodiment of the invention consists in that the guide device is arranged approximately parallel to the broad side of the machine base body. At the guide device, the printing device can be able to be delivered to pressure-relevant areas on the machine base. In particular according to the inkjet method, a print image in a print area can be divided into mutually parallel print lines which together depict the print image. The alignment of the guide device on the machine base body can in particular take place according to the print lines of the print image to be printed on the material to be printed using, for example, the inkjet method, in particular be parallel to the print lines. Thus, by moving print head units along the guide device, a print line of the print image to be printed on the print material can be printed out as required.

Es ist erfindungsgemäß, dass die Führungseinrichtung als eine Portalführung mit einem Querbalken ausgebildet ist, welcher sich in einer breiten Richtung erstreckt und dass die erste Druckkopfeinheit an einer Vorderseite des Querbalkens und die zweite Druckkopfeinheit an einer Rückseite des Querbalkens verfahrbar gelagert ist. Die Führungseinrichtung, insbesondere die Portalführung kann gegenüber dem Maschinengrundkörper, beispielsweise entlang der Längsseite, verfahrbar gelagert sein. Hierdurch kann ein Zustellen von mindestens einer der Druckkopfeinheiten in beliebiger Breitenrichtung entlang der Breitseite des Maschinengrundkörpers durch Verfahren der Druckkopfeinheit entlang der Führungseinrichtung, insbesondere der Portalführung ermöglicht sein. In einer Längsrichtung entlang der Längsseite des Maschinengrundkörpers kann ein Zustellen der Druckkopfeinheiten zu einem zu bedruckenden Bereich auf dem Druckgut durch Verfahren der Führungseinrichtung, insbesondere der Portalführung, ermöglich sein. Die Vorderseite, etwa die vordere Längsseite der Führungseinrichtung insbesondere dem Querbalken der Portalführung kann der Seite zugewandt sein, von welcher aus das zu bedruckende Druckgut initial der Druckvorrichtung zugeführt wird. Die Rückseite der Führungseinrichtung insbesondere die Rückseite des Querbalkens der Portalführung kann eine der Vorderseite entlang der Breitenseite gegenüberliegende Seite an der Führungseinrichtung sein, welche insbesondere der Seite der Druckvorrichtung gegenüber liegt, von welcher initial Druckgut zugeführt werden kann.It is according to the invention that the guide device is designed as a portal guide with a crossbeam which extends in a wide direction and that the first print head unit is movably supported on a front side of the crossbeam and the second print head unit on a rear side of the crossbeam. The guide device, in particular the portal guide, can be mounted so as to be movable relative to the machine base, for example along the longitudinal side. This enables at least one of the print head units to be fed in any desired width direction along the broad side of the machine base by moving the print head unit along the guide device, in particular the portal guide. In a longitudinal direction along the longitudinal side of the machine base body, it can be possible to move the print head units to an area to be printed on the print material by moving the guide device, in particular the portal guide. The front side, for example the front long side of the guide device, in particular the crossbar of the portal guide, can face the side from which the print material to be printed is initially fed to the printing device. The rear side of the guide device, in particular the rear side of the crossbar of the portal guide, can be a side on the guide device opposite the front side along the width side, which is in particular opposite the side of the printing device from which print material can initially be fed.

Nach der Erfindung ist es zweckmäßig, dass die Druckkopfeinheiten der Druckeinrichtung jeweils ausgebildet sind, mehrere nebeneinander bereitgestellte Druckgüter parallel zu bedrucken. Grundsätzlich kann die Translationseinrichtung auch mehrteilig und/oder zur Aufnahme mehrerer Druckgüter ausgebildet sein. Es kann ermöglicht sein, mehrere Druckgüter in einer Breiten- und/oder Längsrichtung auf dem Maschinengrundkörper nebeneinander vorzusehen beziehungsweise auszurichten. Hierdurch kann die Führungseinrichtung oberhalb mehrerer Druckgüter gleichzeitig positioniert werden. Durch ein Verfahren der Druckkopfeinheiten entlang der Führungseinrichtung kann es so ermöglicht sein, mehrere, im Bereich der Führungseinrichtung befindliche Druckgüter ohne ein Verfahren der Führungseinrichtung an dem Maschinengrundkörper zum Zweck des Drucks von mindestens einer Druckzeile oder mindestens eines Teildrucks zu erreichen. Somit kann eine oder unterschiedliche in einer Druck-Linie angeordneten Druckzeilen oder Teildrucke von mehreren zu bedruckenden Druckgütern mit bereits einer (Zeilen-) bewegung einer Druckkopfeinheit entlang der Führungseinrichtung ermöglicht werden, ohne dabei die Führungseinrichtung zwingend zu verfahren. Hierbei kann ein einheitliches Druckbild in Druckbereichen auf den mehreren Druckgütern vorgesehen werden. Ebenfalls können Druckgüter mit individuellen Druckbildern Zeile für Zeile der Druckbilder gemeinsam oder auf einer Auswahl von Druckgütern in oben beschriebener Weise vorgesehen werden.According to the invention, it is expedient that the print head units of the printing device are each designed to print a plurality of print items provided side by side in parallel. In principle, the translation device can also be designed in several parts and / or to accommodate several printed items. It can be possible to provide or align several printing goods next to one another in a width and / or length direction on the machine base body. As a result, the guide device can be positioned above several printed items at the same time. By moving the print head units along the guide device, it can thus be possible to reach several print items located in the region of the guide device without moving the guide device on the machine base for the purpose of printing at least one print line or at least one partial print. Consequently one or different print lines arranged in a print line or partial prints of several print goods to be printed can already be made possible with a (line) movement of a print head unit along the guide device without necessarily moving the guide device. Here, a uniform print image can be provided in print areas on the multiple print items. Likewise, print items with individual print images can be provided line by line of the print images together or on a selection of print items in the manner described above.

Grundsätzlich kann eine Druckzeile eines einzelnen oder mehrere nebeneinander liegender Druckbilder, welcher auf demselben oder unterschiedlichen Druckgütern vorgesehen werden, insbesondere bei einem Druck nach dem Inkjet-Druckverfahren, aus einer definierten Anzahl von Bildpunkten bestehen. Das Druckbild kann ebenfalls aus einer definierten Anzahl einzelner Druckzeilen bestehen, welche wiederum aus Bildpunkten bestehen können. Die erste Druckkopfeinheit und die mindeste zweite Druckkopfeinheit können beim Bedrucken des einen oder der mehreren Druckgüter insofern zusammenwirken, als dass sie jede für sich genommen eine individuelle Zeile des Druckbildes entlang der Führungseinrichtung auf dem mindestens einen Druckgut abdruckt, wodurch die Anzahl an zu druckenden Druckbildzeilen pro Druckbild beziehungsweise pro Druckkopfeinheit reduziert werden kann. Dies kann zu einer Beschleunigung des Druckvorgangs bis zur Beendigung des Druckbildes beziehungsweise eines Druckauftrags mit mehreren Druckbildern auf einem oder mehreren Druckgütern führen. Die Druckkopfeinheiten können auch insofern beim Bedrucken von einem oder mehreren Druckbildern auf einem oder mehreren Druckgütern zusammenwirken, als dass Druckeinheiten eine definierte Anzahl der pro Zeile zu druckenden Bildpunkte drucken, welche geringer ist als die Gesamtzahl der pro Druckzeile zu druckenden Druckpunkte, wobei die mindestens zweite Druckkopfeinheit die übrigen, nicht von der ersten Druckkopfeinheit gedruckten Druckpunkte jeder Zeile druckt.In principle, a print line of a single print image or a plurality of print images lying next to one another, which are provided on the same or different print goods, in particular when printing using the inkjet printing method, can consist of a defined number of pixels. The print image can also consist of a defined number of individual print lines, which in turn can consist of pixels. The first printhead unit and the at least second printhead unit can cooperate when printing the one or more print items in that they each individually print an individual line of the print image along the guide device on the at least one print item, whereby the number of print image lines to be printed per Print image or per print head unit can be reduced. This can lead to an acceleration of the printing process up to the completion of the print image or a print job with multiple print images on one or more print items. The print head units can also cooperate when printing one or more print images on one or more print items, as that print units print a defined number of the image points to be printed per line, which is less than the total number of the print points to be printed per print line, the at least second Print head unit prints the remaining print dots of each line that were not printed by the first print head unit.

Ein Aspekt der erfindungsgemäßen Vorrichtung besteht darin, dass die Druckkopfeinheiten der Druckkopfeinrichtung ausgebildet sind, das mindestens eine Druckgut sowohl gemeinsam als auch unabhängig voneinander mit einem Druckbild zu bedrucken. Die mehreren Druckkopfeinheiten, welche frei entlang der Führungseinrichtung verfahrbar sein können, können individuell beziehungsweise unabhängig einzelnen nebeneinander angeordneten Druckgütern zugestellt werden, um diese jeweils für sich genommen zumindest mit einer Druckzeile oder einem Teildruck zu bedrucken. Hierbei kann insbesondere die Anzahl von Druckkopfeinheiten im Betrieb sein, welche der Anzahl der parallel zu bedruckenden Druckgüter entspricht. Weitere an der Druckvorrichtung vorgesehene Druckeinheiten können die Druckgüter unterstützend mitbedrucken. Entspricht also die Anzahl der parallel zu bedruckenden Druckgüter der Anzahl der vorgesehenen Druckkopfeinheiten, können diese jeweils vorgesehen werden für sich genommen jeweils ein Druckgut zu bedrucken. Ebenfalls können die Druckeinrichtungen ganz oder teilweise zusammen wirken, mindestens ein Druckgut gemeinsam mit einem oder mehreren Druckbildern zu bedrucken.One aspect of the device according to the invention is that the printhead units of the printhead device are designed to print the at least one print item both jointly and independently of one another with a print image. The multiple printhead units that freely move along the guide device can be moved, can be delivered individually or independently to individual print items arranged next to one another, in order to print them individually with at least one print line or a partial print. In particular, the number of print head units in operation can be that corresponds to the number of print items to be printed in parallel. Further printing units provided on the printing device can also support the printing of the printed matter. Thus, if the number of print items to be printed in parallel corresponds to the number of printhead units provided, these can each be provided for printing one print item each. Likewise, the printing devices can work together wholly or partially to print at least one print item together with one or more print images.

Nach einer Weiterbildung des erfindungsgemäßen Verfahrens ist es bevorzugt, dass die erste Druckkopfeinheit entlang einer ersten Längsseite der Führungseinrichtung und die mindestens zweite Druckeinheit entlang einer zweiten Längsseite der Führungseinrichtung verfahren wird. Durch die Anordnung von Druckkopfeinheiten an unterschiedlichen Seiten der Führungseinrichtung insbesondere dem Querbalken der Portalführung kann ein Verfahren der Druckkopfeinheiten entlang der Führungseinrichtung ungehindert und unabhängig voneinander ermöglicht sein. Insbesondere kann jede der an der Führungseinrichtung vorgesehenen Druckkopfeinheiten druckrelevanten Punkten entlang der Führungseinrichtung insbesondere entlang des Querbalkens der Portalführung oberhalb des Maschinengrundkörpers zugestellt werden, ohne dabei Rücksicht auf die Position einer weiteren Druckkopfeinheit nehmen zu müssen oder durch die Position der weiteren Druckkopfeinheit behindert zu sein.According to a further development of the method according to the invention, it is preferred that the first print head unit is moved along a first longitudinal side of the guide device and the at least second printing unit is moved along a second longitudinal side of the guide device. The arrangement of print head units on different sides of the guide device, in particular the crossbar of the portal guide, enables the print head units to be moved along the guide device without hindrance and independently of one another. In particular, each of the print head units provided on the guide device can be fed to print-relevant points along the guide device, in particular along the crossbar of the portal guide above the machine base, without having to take into account the position of a further print head unit or being hindered by the position of the further print head unit.

Besonders bevorzugt ist es nach einer Weiterbildung des erfindungsgemäßen Verfahrens, dass die Druckkopfeinheiten das Druckgut bedarfsgerecht gemeinsam oder unabhängig voneinander mit dem Druckbild bedrucken.According to a further development of the method according to the invention, it is particularly preferred that the print head units print the print material with the print image either jointly or independently of one another as required.

Die Erfindung wird nachfolgend anhand der beigefügten, schematischen Zeichnung weiter erläutert. In der Zeichnung zeigtThe invention is explained in more detail below with reference to the attached schematic drawing. In the drawing shows

Figur 1: eine schematische Darstellung einer bevorzugten Ausführungsform der erfindungsgemäßen Druckvorrichtung. Figure 1 : a schematic representation of a preferred embodiment of the printing device according to the invention.

In Figur 1 ist eine Druckvorrichtung 10 in perspektivischer Darstellung abgebildet. Die Druckvorrichtung 10 weist einen Maschinengrundkörper 20 mit einer Längsseite 21 und einer Breitseite 22 auf. Die Längs- und Breitseite 21/22 können insbesondere in etwa rechtwinklig zueinander vorgesehen sein. Auf dem Maschinengrundkörper 20 ist eine Translationsvorrichtung 30 angeordnet, welche mehrere Schlitten 31 aufweist. Die Schlitten 31 können mittels eines Fördermittels 32 entlang der Längsseite 21 in Längsrichtung auf dem Maschinengrundkörper 20 verfahrbar gelagert sein. Hierbei kann es sich insbesondere im Falle der Schlitten um eine Schlittenführung, insbesondere mit einer Führungs-Kette oder einen Rippenriemen zum Verfahren beziehungsweise Bewegen der Translationseinrichtung 30 handeln. Oberhalb des Maschinengrundkörpers 20 ist eine Führungseinrichtung 40 angeordnet, welche als Portalführung ausgestaltet ist. Die Führungseinrichtung insbesondere die Portalführung weist einen Querbalken 43 auf, an welchem an einer Vorderseite eine erste Druckkopfeinrichtung 41 und an einer Rückseite des Querbalkens 43 eine zweite Druckkopfeinrichtung 42 angeordnet ist.In Figure 1 a printing device 10 is shown in perspective. The printing device 10 has a machine base body 20 with a longitudinal side 21 and a broad side 22. The longitudinal and broad sides 21/22 can in particular be provided approximately at right angles to one another. A translation device 30, which has a plurality of carriages 31, is arranged on the machine base body 20. The carriages 31 can be mounted so that they can be moved along the longitudinal side 21 in the longitudinal direction on the machine base body 20 by means of a conveyor 32. In the case of the carriages in particular, this can be a carriage guide, in particular with a guide chain or a ribbed belt for moving or moving the translation device 30. A guide device 40, which is designed as a portal guide, is arranged above the machine base body 20. The guide device, in particular the portal guide, has a crossbar 43 on which a first print head device 41 is arranged on a front side and a second print head device 42 is arranged on a rear side of the crossbar 43.

Bedarfsgerecht kann die Anzahl an Druckkopfeinheiten an der Führungseinrichtung 40 angepasst werden, wobei auch mehr als zwei Druckkopfeinheiten vorsehbar sind. Gemeinsam können die Druckkopfeinheiten die Druckeinrichtung bilden. Insbesondere die erste Druckkopfeinheit 41 und die zweite Druckkopfeinheit 42 können entlang ihrer jeweiligen Seiten des Querbalkens 43 parallel zur Breitseite 22 des Maschinengrundkörpers 20 verfahrbar gelagert sein. Somit können die Druckkopfeinheiten individuell und unabhängig druckrelevanten Bereichen auf dem Maschinengrundkörper in Breitenrichtung an der Führungseinrichtung 40 zugestellt werden. Druckrelevant können insbesondere solche Bereiche auf der Oberfläche des Maschinengrundkörpers sein, auf welchen ein Druckerfarbentröpfchen oder ein Teildruck auf ein unter der Druckeinrichtung befindliches Druckgut 1 gedruckt werden soll.The number of print head units on the guide device 40 can be adapted as required, it also being possible to provide more than two print head units. Together, the print head units can form the printing device. In particular, the first print head unit 41 and the second print head unit 42 can be mounted so as to be movable along their respective sides of the crossbar 43 parallel to the broad side 22 of the machine base body 20. Thus, the print head units can be individually and independently fed to print-relevant areas on the machine base in the width direction on the guide device 40. In particular, those areas on the surface of the machine base body on which a printer ink droplet or a partial print is to be printed on a print item 1 located under the printing device can be print-relevant.

Ist beispielsweise ein einzelnes Druckgut 1 auf der Translationseinrichtung 30 der Druckvorrichtung 10 vorgesehen, können die einzelnen Druckkopfeinheiten, insbesondere die erste Druckkopfeinheit 41 und die zweite Druckkopfeinheit 42, beispielsweise zeilenweise oder durch das individuelle Drucken einzelner Druckbildpunkte das Druckbild auf dem Druckgut 1 gemeinsam erstellen. Auch ist es möglich, jede Druckkopfeinheit einen separaten Druckbereich oder Druckbild zuzuordnen, welches diese dann mit einem Druckbild bedruckt.For example, if a single print item 1 is provided on the translation device 30 of the printing device 10, the individual print head units, in particular the first print head unit 41 and the second print head unit 42, can create the print image on the print item 1 together, for example line by line or by individually printing individual print image points. It is also possible to use any Assigning a separate print area or print image to the print head unit, which then prints a print image on it.

Ist mehr als ein Druckgut auf der Translationseinheit 30 vorgesehen, können die Druckkopfeinheiten die Druckgüter sowohl einzeln bedrucken, also eine erste Drucckopfeinheit eines ersten Druckguts und die weiteren Druckkopfeinheiten jeweils eines weiteren Druckguts. Die Druckkopfeinheiten können die Druckgüter auch gemeinsam bedrucken, wobei die zu bedruckenden Druckgüter nebeneinander parallel zur Breitseite 22 und insbesondere parallel zu der Führungseinrichtung 40 angeordnet werden können und die Druckköpfe oberhalb der Druckgüter zum Bedrucken der selbigen an der Führungseinrichtung 40 verfahren werden können. So können Druckbilder auf den einzelnen Druckgütern beispielsweise gemeinsam durch die vorhandenen Druckkopfeinheiten der Druckeinrichtung gebildet werden, wobei mit einer (Zeilen-)bewegung einer Druckkopfeinheit entlang der Führungseinrichtung eine Druckzeile auf dem einen oder den mehreren Druckgütern aufgetragen werden kann.If more than one print item is provided on the translation unit 30, the print head units can print the print items individually, that is, a first print head unit of a first print item and the further print head units each of a further print item. The print head units can also print the goods to be printed together, whereby the goods to be printed can be arranged next to one another parallel to the broad side 22 and in particular parallel to the guide device 40 and the print heads can be moved above the goods for printing on the guide device 40. For example, print images on the individual print items can be formed jointly by the existing print head units of the printing device, whereby a print line can be applied to the one or more print items with a (line) movement of a print head unit along the guide device.

Zum Beschleunigen des Zustellens der Druckkopfeinheit(en) zwischen verschiedenen Druckbereichen und/oder Druckteilbereichen auf dem Maschinengrundkörper 20 kann die Führungseinrichtung 30, insbesondere die Portalführung am Maschinengrundkörper 20 verfahrbar, beispielsweise entlang der Längsseite 21 des Maschinengrundkörpers 20 gelagert sein. Somit kann beispielsweise ein Druckgut 1 von einer ersten Position an einem vorderen Ende des Maschinengrundkörpers, wie in Figur 1 abgebildet zu einer zweiten Position, beispielsweise am gegenüberliegenden Ende des Maschinengrundkörpers 20 verfahren werden und während des Verfahrens, jedoch auch während das Druckgut an einem beliebigen Punkt auf der Maschinengrundkörperoberfläche ruht, durch die Führungseinrichtung erreicht und durch die Druckeinrichtung mit Druckerfarbe bedruckt werden. Die Position der Druckeinrichtung beziehungsweise der Druckkopfeinrichtung(en) kann also in Längsrichtung des Maschinengrundkörpers gegenüber dem Maschinengrundkörper, der Translationseinrichtung beziehungsweise dem mindestens einen Druckgut durch ein Verfahren der Führungseinrichtung veränderbar sein.To accelerate the infeed of the printhead unit (s) between different printing areas and / or printing subareas on the machine base 20, the guide device 30, in particular the portal guide on the machine base 20, can be movably mounted, for example along the longitudinal side 21 of the machine base 20. Thus, for example, a print item 1 can be moved from a first position at a front end of the machine base body, as in FIG Figure 1 mapped to a second position, for example at the opposite end of the machine base body 20, and during the process, but also while the print material rests at any point on the machine base body surface, are reached by the guide device and printed with ink by the printing device. The position of the printing device or the print head device (s) can thus be changed in the longitudinal direction of the machine base body relative to the machine base body, the translation device or the at least one print item by moving the guide device.
