Der Erfindung liegt die Aufgabe zugrunde, eine Maschine der eingangs genannten Art zu schaffen, die sich in einen fortlaufenden Fertigungsprozeß für plattenförmige Werkstücke, nämlich für Möbelteile oder Bauelemente, leicht eingliedern läßt, um mittels des Ink-Jet-Drucksystems die Einfärbung der Oberfläche an den Schmalflächenseiten der Werkstücke vorzunehmen.The invention has for its object to provide a machine of the type mentioned, which can be easily incorporated into a continuous manufacturing process for plate-shaped workpieces, namely for furniture parts or components, by means of the ink-jet printing system, the coloring of the surface of the Make narrow sides of the workpieces.
Diese Aufgabe wird bei einer Maschine der oben genannten Art dadurch gelöst, daß die Werkstücke plattenförmige Bauteile oder Bauelemente sind, deren Schmalseiten bedruckt werden, wobei diese Werkstücke horizontal flachliegend auf der Werkstückaufnahmevorrichtung befördert werden und die Druckköpfe den Schmalseiten der auf der Werkstückaufnahmevorrichtung aufgenommenen, plattenförmigen Werkstücke gegenüberliegend sowie in der Längsrichtung dieser Schmalseiten hintereinander angeordnet und verschiedenen Höhenbereichen der Werkstückschmalseiten zugeordnet sind, wobei die Farbmodule jedes Druckkopfes je für sich für einen Farbauftrag auf die Werkstück-Schmalseiten vorgesehen sind und wobei oberhalb der Werkstückaufnahmevorrichtung eine die Werkstücke darauf niederhaltende Oberdruckvorrichtung angeordnet ist.This object is achieved in a machine of the type mentioned above in that the workpieces are plate-shaped components or components whose narrow sides be printed, these workpieces are transported horizontally lying flat on the workpiece receiving device and the printheads the narrow sides of the recorded on the workpiece receiving device, plate-shaped workpieces arranged opposite each other and in the longitudinal direction of these narrow sides and assigned to different height ranges of the workpiece narrow sides, the color modules each printhead depending on are provided for an application of ink on the workpiece narrow sides and wherein above the workpiece receiving device, the workpieces low-holding upper pressure device is arranged.
Für die Erfindung ist wesentlich, daß die Relativbewegung zwischen der Werkstückaufnahmevorrichtung und dem Ink-Jet-Drucksystem mit relativ hoher Geschwindigkeit durchgeführt werden kann. Die neue Maschine ist speziell auf das Bedrucken der Schmalseiten der plattenförmigen Werkstücke zugeschnitten. Ein solches Möbelteil oder Bauteil wird ausgehend von dem jeweiligen Grundwerkstück, wie einem auf den Breitseiten beschichteten, oberflächenfertigen Spanplattenmaterial an seinen Schmalseiten für eine Veredelung durch Bedrucken vorbereitet. Dies geschieht entweder durch eine Bekantung der Werkstück-Schmalseiten mittels Kunststoff-, Holz- oder sonstigen Kantenmaterialien oder durch Versiegeln der Werkstück-Schmalseiten mittels eines Schmelzklebers, einem Lack oder dergleichen. Des weiteren ist es möglich, solche Werkstücke einzusetzen, deren Schmalseiten bereits eine "Druckqualität" aufgrund ihres Ausgangswerkstoffes aufweisen, um sie nach dem Ink-Jet-Druckverfahren bedrukken zu können. Gerade die Beschränkung auf ein Bedrukken lediglich der Schmalseiten der plattenförmigen Werkstücke bringt erhebliche Fertigungsvorteile bei der Herstellung von Möbelteilen und Bauelementen, und darauf ist die erfindungsgemäße Maschine abgestellt.It is essential to the invention that the relative movement between the workpiece-receiving device and the ink-jet printing system can be carried out at a relatively high speed. The new machine is specially tailored to the printing of the narrow sides of the plate-shaped workpieces. Such a furniture part or component is based on the respective base workpiece, such as a coated on the broad sides, surface-ready particle board material on its narrow sides for finishing prepared by printing. This is done either by an edging of the workpiece narrow sides by means of plastic, wood or other edge materials or by sealing the workpiece narrow sides by means of a hot melt adhesive, a paint or the like. Furthermore, it is possible to use such workpieces whose narrow sides already have a "print quality" due to their starting material in order to be able to print them by the ink-jet printing process. Just the restriction to Bedrukken only the narrow sides of the plate-shaped workpieces brings significant manufacturing advantages in the production of furniture parts and components, and the machine of the invention is turned off.
Vorteilhafte Ausgestaltungsmerkmale der Erfindung ergeben sich aus den Unteransprüchen.Advantageous design features of the invention will become apparent from the dependent claims.
Die Erfindung wird nachfolgend anhand der Zeichnung an einem Ausführungsbeispiel noch näher erläutert. Die Zeichnung zeigt die wesentlichen Teile einer Maschine zum Bedrucken der Schmalseiten plattenförmiger Möbelteile oder Bauelemente in schematischer, perspektivischer Ansicht schräg von oben her gesehen.The invention will be explained in more detail with reference to the drawing of an embodiment. The drawing shows the essential parts of a machine for printing the narrow sides of plate-shaped furniture parts or components seen in a schematic, perspective view obliquely from above.
Im einzelnen weist die dargestellte Maschine eine Werkstückaufnahmevorrichtung 1 in Gestalt einer Transportvorrichtung auf, bei der es sich um ein endlos umlaufendes Förderband, eine Kette oder dergleichen handelt.In detail, the illustrated machine has a workpiece receiving device 1 in the form of a transport device, in which it is an endlessly circulating conveyor belt, a chain or the like.
Auf der Werkstückaufnahmevorrichtung 1 werden Werkstükke 2 flachliegend aufgenommen, die an zumindest einer der in der Förderrichtung der Werkstückaufnahmevorrichtung 1 liegenden Schmalseiten 3 bedruckt werden. Zum Niederhalten der Werkstücke 2 auf der Werkstückaufnahmevorrichtung 1 kann ein in der Zeichnung nicht dargestellter Oberdruck vorgesehen werden.On the workpiece receiving device 1 Werkstükke 2 are recorded lying flat, which are printed on at least one of the lying in the conveying direction of the workpiece receiving device 1 narrow sides 3. For holding down the workpieces 2 on the workpiece receiving device 1, a not shown in the drawing, top pressure can be provided.
Die Werkstücke 2 können an ihren zu bedruckenden Schmalseiten 3 vorbehandelt sein. Je nachdem wird vor dem Bedrucken auf die Werkstück-Schmalseiten 3 ein Grundierstoff aufgetragen, dieser Vorgang kann mit in den Bedruckungsprozeß einbezogen sein. Bei der gesamten Maschine, bei welcher die Werkstückaufnahmevorrichtung 1 als Transportvorrichtung ausgebildet ist, handelt es sich um eine im Durchlauf der Werkstücke 2 arbeitende Maschine, also um eine sogenannte Durchlaufmaschine.The workpieces 2 can be pretreated at their to be printed narrow sides 3. Depending on whether a primer is applied to the workpiece narrow sides 3 before printing, this process can be included in the printing process. In the entire machine, in which the workpiece receiving device 1 is designed as a transport device, is a working in the passage of the workpieces 2 machine, ie a so-called continuous machine.
Die Maschine weist eine Plattform 4 auf, entlang dem sich die Werkstückaufnahmevorrichtung 1 erstreckt. Auf dieser Plattform 4 sind die einzelnen Bearbeitungsaggregate für die Vorbehandlung, die Bedruckung und die Nachbehandlung der Werkstücke 2 in der Durchlaufrichtung hintereinander angeordnet, und zwar so, daß sie sich im wesentlichen auf Höhe der vorbeilaufenden Werkstück-Schmalseiten 3 befinden.The machine has a platform 4, along which the workpiece receiving device 1 extends. On this platform 4, the individual processing units for the pretreatment, the printing and the post-treatment of the workpieces 2 in the direction of passage are arranged one behind the other, in such a way that they are located substantially at the height of the passing workpiece narrow sides 3.
An der Einlaufseite der Maschine ist eine Primereinheit 5 angeordnet, mit der erforderlichenfalls ein Grundierwerkstoff auf die zu bedruckenden Werkstück-Schmalseiten 3 aufgebracht werden kann, was vorzugsweise mittels eines Sprühkopfes bei geeigneter Konsistenz des Grundierwerkstoffes geschieht. Eine solche Vorbehandlung verbessert zum einen die Haftung und verhindert zum anderen das Verlaufen der Druckfarbe, und es kann auf das Saugverhalten der behandelten Werkstückschmalseiten 3 Einfluß genommen werden, um den Druckfarbenverbrauch und die Deckfähigkeit der Druckfarbe exakt zu bestimmen, um eine hohe Oberflächenqualität zu erzielen. Die Werkstück-Schmalseiten erhalten hierdurch nach der Grundierung eine möglichst unifarbene, insbesondere weiße, glatte und homogene Oberfläche.On the inlet side of the machine, a primer unit 5 is arranged, with the primer material if necessary can be applied to the workpiece narrow sides 3 to be printed, which is preferably done by means of a spray head with a suitable consistency of the primer. On the one hand, such a pretreatment improves the adhesion and on the other hand prevents the ink from running, and it can influence the absorption behavior of the treated narrow sides 3 of the workpiece in order to precisely determine the ink consumption and the opacity of the ink in order to achieve a high surface quality. As a result, the workpiece narrow sides receive, after the primer, a surface which is as unicoloured as possible, in particular white, smooth and homogeneous.
In der Auflaufrichtung der Werkstücke 2 gesehen ist die Werkstückaufnahmevorrichtung 1 entlang einem Ink-Jet-Drucksystem 6 vorbeigeführt, welches beim Ausführungsbeispiel drei Druckköpfe 7 aufweist. Die Druckköpfe 7 befinden sich ebenfalls in Höhe der vorbeilaufenden Werkstück-Schmalseiten 3, und sie sind ihnen gegenüberliegend mit verhältnismäßig geringem Abstand angeordnet. In Höhenrichtung der Werkstückschmalseiten 3 gesehen bestreicht jeder der Druckköpfe 7 einen Bereich der Werkstück-Schmalseiten 3, weswegen die Druckköpfe 7 relativ zueinander in der Höhe versetzt angeordnet sind. So hängt die Anzahl der vorzusehenden Druckköpfe 7 auch davon ab, welche maximale Höhe die Werkstückschmalseiten 3 haben.As seen in the direction of feed of the workpieces 2, the workpiece receiving device 1 is guided past an ink-jet printing system 6, which has three print heads 7 in the exemplary embodiment. The print heads 7 are also in the amount of passing workpiece narrow sides 3, and they are arranged opposite them with a relatively small distance. Seen in the height direction of the workpiece narrow sides 3, each of the print heads 7 strikes a region of the workpiece narrow sides 3, for which reason the print heads 7 are arranged offset relative to one another in height. Thus, the number of print heads 7 to be provided also depends on the maximum height of the workpiece narrow sides 3.
Mit dem Ink-Jet-Drucksystem 6 ist es möglich, den vorbehandelten Werkstück-Schmalseiten 3 ein individuelles Oberflächenmuster zu geben. Um die Variationsmöglichkeiten zu vergrößern besteht jeder Druckkopf 7 des Ink-Jet-Drucksystems 6 aus einer Mehrzahl von Farbmodulen 8, wobei je nach dem gewünschten Druckmuster die einzelnen Farbmodule 8 für gleiche oder unterschiedliche Farben eingerichtet sein können.With the ink-jet printing system 6, it is possible to give the pretreated workpiece narrow sides 3 an individual surface pattern. In order to increase the possibilities of variation, each print head 7 of the ink-jet printing system 6 consists of a plurality of color modules 8, it being possible for the individual color modules 8 to be set up for the same or different colors, depending on the desired print pattern.
Die Druckköpfe 7 des Ink-Jet-Drucksystems 6 sind mittels Stellvorrichtungen 10 räumlich justierbar, die sich auf einem Träger 9 befinden. Der Träger 9 kann in seiner Gesamtheit auf der Plattform 4 verstellbar angeordnet sein. Die schematisch wiedergegebenen Stellvorrichtungen 10, an denen die Druckköpfe 7 gehalten sind, weisen Höhenführungen 11 auf, um die Druckköpfe 7 in Höhenrichtung der Werkstück-Schmalseiten 3 verstellen zu können. Ferner sind an den Stellvorrichtungen 10 Querführungen 12 vorhanden, über die der Abstand der Druckköpfe 7 von den vorbeilaufenden Werkstück-Schmalseiten 3 variiert werden kann. Zusätzlich kann noch eine Schwenkeinrichtung an den Stellvorrichtungen 10 vorgesehen werden, um eine Neigungsverstellung der Druckköpfe 7 zu ermöglichen. Insgesamt wird damit eine Verstellmöglichkeit der Druckköpfe 7 in den üblichen drei senkrecht zueinander stehenden Achsen einer programmgesteuerten Maschine erreicht.The printheads 7 of the ink-jet printing system 6 are spatially adjustable by means of adjusting
In der Durchlaufrichtung der Werkstücke 2 gesehen, schließt sich an das Ink-Jet-Drucksystem 6 zunächst eine Trocknereinheit 13 an. Mittels dieser Trocknereinheit 13 wird die auf die Werkstück-Schmalseiten 3 aufgebrachte Druckfarbe völlig abgetrocknet.When viewed in the direction of passage of the workpieces 2, the inkjet printing system 6 is initially followed by a
In Durchlaufrichtung hinter der Trocknereinheit 13 befinden sich eine oder mehrere Einheiten 14, die für das Finishen der bedruckten Werkstück-Schmalseiten 3 bestimmt sind. Hier wird den Werkstück-Schmalflächenseiten 3 eine Oberflächenvergütung oder -versiegelung gegeben, wozu auf die Werkstück-Schmalseiten 3 eine Schutzschicht aufgebracht wird. Diese Schutzschicht erzeugt eine gegen äußere Einflüsse, wie Wasser, UV-Strahlen, Schläge, Kratzer oder dergleichen, resistente Oberfläche. Das Finishen der Oberflächen der Werkstück-Schmalseiten 3 kann mit unterschiedlichen Vorrichtungen vorgenommen werden, um die entsprechende Schutzschicht aufzuspritzen, aufzusprühen oder aufzurollen. Es kann sich hierbei um eine glasklare, eine strukturierte oder eine mattierte Schutzschicht handeln, auch ist eine Nachbehandlung der Schutzschicht zur Erzeugung einer Strukturierung oder Mattierung möglich.In the direction of passage behind the
