Description

Die Erfindung betrifft ein Verfahren, eine Vorrichtung und ein System zum Herstellen von Bauteilen mit vorbestimmtem Oberflächenaussehen, insbesondere von Frontplatten von Küchenelementen. Aus US-A-5117610 ist ein Verfahren zum Herstellen von Objekten mit vorbestimmtem Oberflächeaussehen bekannt.The invention relates to a method, a device and a system for producing components with a predetermined surface appearance, in particular front panels of kitchen elements. Out US-A-5117610 For example, a method for producing objects having a predetermined surface appearance is known.

Ein Konstruktionsmerkmal üblicher Küchen liegt darin, daß unterschiedlichste Küchenelemente, Schubladen, Schränke, Elektrogeräte usw. mit Frontplatten versehen werden, die der Küche ein eigenes und gefälliges Aussehen verleihen. Die Vielzahl von Frontplattengrößen und die Vielzahl von von den Kunden gewünschten Oberflächen, die unterschiedliche Holzarten, Kunststoffoberflächen, unterschiedliche Farben und Muster umfassen, führt zu einer außerordentlich kostenintensiven Produktion mit großer Lagerhaltung. Beispielweise werden Frontplatten aus unterschiedlichem Massivholz oder mit unterschiedlichen Holzfurnieren hergestellt, die dann in der gewünschten Farbe gebeizt und oberflächenversiegelt werden.A design feature of conventional kitchens is that a variety of kitchen items, drawers, cabinets, electrical appliances, etc. are provided with front panels that give the kitchen its own and pleasing appearance. The variety of front panel sizes and the variety of customer-requested surfaces, which include different types of wood, plastic surfaces, different colors and patterns, results in extremely costly, high inventory production. For example, front panels are made of different solid wood or with different wood veneers, which are then stained in the desired color and surface-sealed.

Der Erfindung liegt die Aufgabe zu Grunde, die vorgenannte Problematik zu mildem.The invention is based on the object to alleviate the aforementioned problem.

Das im Anspruch 1 gekennzeichnete Verfahren liefert eine Lösung für das vorgenannte Problem.The method characterized in claim 1 provides a solution to the aforementioned problem.

Mit dem erfindungsgemäßen Verfahren können aus Formteilen, deren Form der der herzustellenden Bauteile entspricht, Bauteile mit unterschiedlichstem Aussehen hergestellt werden, obwohl die bedruckten Formteile gleiche Oberflächen oder Formteile verwendet werden, die hinsichtlich ihres Oberflächenmaterials eine wesentlich geringere Vielfalt aufweisen als die bedruckten, herzustellenden Bauteile. Beispielsweise kann mit Formteilen mit lediglich zwei Arten von Oberflächen gearbeitet werden, um eine außerordentlich große Vielfalt zu erzielen. Die eine Art von Formbauteilen weist eine Kunststoffoberfläche auf und die andere Art von Formbauteilen weist eine Holzfurnieroberfläche auf. Auf die Kunststoffoberfläche können unterschiedlichste Farben und/oder Muster gedruckt werden, um ein entsprechendes Aussehen zu erzeugen. Auf die Holzfurnieroberfläche können unterschiedlichste Holzmaserungen aufgedruckt werden, die das Aussehen unterschiedlichster Holzarten mit unterschiedlichsten Einfärbungen ergeben, ohne dass die jeweilige Holzart tatsächlich verwendet werden muß. Überraschenderweise hat sich herausgestellt, dass eine Grundmaserung der Furnieroberfläche oder auch einer Vollholzoberfläche einem Bedrucken mit anderen Maserungen nicht entgegensteht und durch entsprechende Abstimmung der Farbintensitäten das Aussehen der aufgedruckten Maserung nicht nachteilig beeinflußt. Mit dem erfindungsgemäßen Verfahren ist es somit möglich, eine außerordentlich hohe Aussehensvielfalt, d.h. insbesondere vom Kunden gewünschte Vielfalt mit einer geringen Vielfalt von Rohteilen zu erzeugen.With the method according to the invention can be made of molded parts whose shape corresponds to the components to be produced, components with different looks, although the printed moldings same surfaces or moldings are used, which have a much lower diversity in terms of their surface material as the printed components to be produced. For example, you can work with moldings with only two types of surfaces to achieve an extremely wide variety. One type of molded component has a plastic surface and the other type of molded component has a wood veneer surface. On the plastic surface a variety of colors and / or patterns can be printed to produce a corresponding appearance. On the wood veneer surface a variety of wood grains can be printed, which give the appearance of different types of wood with different colorations, without the respective type of wood must actually be used. Surprisingly, it has been found that a basic grain of the veneer surface or a solid wood surface does not preclude printing with other grains and by appropriate coordination of the color intensities does not adversely affect the appearance of the printed grain. With the method according to the invention it is thus possible to produce an extraordinarily high variety of appearance, ie in particular variety desired by the customer with a small variety of blanks.

Die Unteransprüche 2 bis 11 sind auf vorteilhafte Durchführungsformen des erfindungsgemäßen Verfahrens gerichtet.The dependent claims 2 to 11 are directed to advantageous embodiments of the method according to the invention.

Die zu bedruckenden Oberflächen können derart vorbehandelt werden, dass sie Färbeflüssigkeiten, die wegen des verwendeten Druckverfahrens, beispielsweise in einem Tintendruckstrahlverfahren, bestimmten Einschränkungen unterworfen sind, gut aufnehmen. Auf diese Weise können die zu bedruckende Oberfläche und die Färbeflüssigkeiten aufeinander abgestimmt werden. Bei Holzoberflächen kann eine Vorbehandlung auch darin bestehen, dass das Holz in vorbestimmter Weise in Art einer Lasur behandelt wird, dass seine Porosität bzw. sein Flüssigkeitsaufnahmevermögen auf das dann verwendete Druckverfahren abgestimmt wird oder das Holz mit einer bestimmten Grundtönung versehen wird.The surfaces to be printed can be pretreated in such a way that they absorb well dye liquids, which are subject to certain restrictions because of the printing process used, for example in an ink-jet printing process. In this way, the surface to be printed and the dyeing liquids can be matched to one another. In the case of wood surfaces, pretreatment can also consist in the wood being treated in a predetermined manner in the manner of a glaze, that its porosity or its liquid absorption capacity be matched to the printing method then used or the wood is provided with a certain basic tint.

Die bedruckte Oberfläche läßt sich versiegeln oder mit sonstigen Beschichtüngen versehen, die beispielsweise mechanisch sehr unempfindlich sind, für UV-Licht nicht durchlässig sind usw..The printed surface can be sealed or provided with other coatings, which are for example mechanically very insensitive, are not permeable to UV light, etc.

Mit dem erfindungsgemäßen System ist es vollautomatisch oder weitgehend automatisiert möglich, bei sehr geringer Vielfalt an Bauteilmaterial bzw. Rohmaterial eine außerordentlich hohe Vielfalt vor Kunde zu erzielen, ohne dass eine kostenintensive Lagerhaltung weitgehend fertiger und damit teurer Teile erforderlich ist. Mit dem erfindungsgemäßen System kann vielmehr praktisch "just in time" auf Bestellung produziert werden.With the system according to the invention, it is fully automatic or largely automated, with a very small variety of component material or raw material an extraordinary To achieve a high level of diversity before the customer, without the costly storage of largely finished and thus more expensive parts is required. With the system according to the invention, it is possible to produce virtually "just in time" to order.

Die Erfindung ist überall dort einsetzbar, wo an Bauteilen bezüglich des Aussehens eine hohe Vielfalt vor Kunde mit geringen Kosten erreicht werden soll. Besonders vorteilhaft ist die Erfindung bei flächigen Bauteilen einsetzbar, bei denen aus plattenartigem Rohmaterial zunächst Zuschnitte mit vorbestimmter Form hergestellt werden, die dann das gewünschte Oberflächenaussehen erhalten. Ein Einsatzgebiet, für die sich die Erfindung besonders gut eignet, ist die Möbelindustrie, in der Möbel, beispielsweise auch Küchenmöbel, aus flächigen Bauteilen zusammengesetzt werden, die nach innen und nach außen unterschiedliches Aussehen haben sollen, wobei insbesondere das Aussehen von außen in hohem Maße kundenindividuell und qualitativ hochwertig sein muß.The invention can be used anywhere where a high diversity is to be achieved before customers with low cost components on the appearance. Particularly advantageous is the invention can be used in sheet-like components in which blanks are first made of plate-like raw material with a predetermined shape, which then receive the desired surface appearance. A field of application for which the invention is particularly well suited is the furniture industry, in which furniture, for example kitchen furniture, is composed of sheet-like components which are to have different outward and outward appearances, in particular the external appearance to a great extent must be customized and of high quality.

Figur 1 zeigt beispielhaft zwei Frontplatten 2, wobei die linke eine Holzoberfläche mit einer Maserung 4 aufweist und die rechte eine homogene Kunststoffoberfläche aufweist. Die Frontplatten können unterschiedlichsten Aufbau und Oberflächen haben, beispielsweise einen Preßspangrundkörper, auf den ein Holzfurnier aufgebracht ist, einen Kunststoffgrundkörper, auf den Material aufkaschiert ist, so daß die Oberfläche dreidimensional strukturiert ist, usw. Die Frontplatten können auch aus Massivholz sein. FIG. 1 shows by way of example two front panels 2, wherein the left has a wooden surface with a grain 4 and the right has a homogeneous plastic surface. The front panels can have a variety of structures and surfaces, such as a Preßspangrundkörper on which a wood veneer is applied, a plastic base, is laminated to the material, so that the surface is structured in three dimensions, etc. The front panels can also be made of solid wood.

Die gestrichelt eingezeichneten Linien 6 sind Konturlinien zur Verdeutlichung, daß die Frontplatten in unterschiedlichsten Größen benötigt werden, wobei auch nicht rechtwinklige Frontplatten, runde und ovale Frontplatten usw. vorgesehen sein können.The dashed lines 6 are contour lines to illustrate that the front panels are needed in a variety of sizes, including non-rectangular face plates, round and oval face plates, etc. may be provided.

Figur 2a zeigt in einer Aufsicht und Figur 2b in einer Seitenansicht eine Vorrichtung zum Aufbringen vorbestimmter Muster auf eine Frontplatte 2. FIG. 2a shows in a supervision and FIG. 2b in a side view, a device for applying predetermined patterns on a front panel. 2

Die Frontplatte 2 befindet sich auf einer Fördereinrichtung 8, die beispielsweise ein über Rollen bzw. Walzen 10 bewegtes Förderband 12 enthält, zu dessen Antrieb ein Motor 14 vorgesehen ist.The front panel 2 is located on a conveyor 8, which contains, for example, a conveyor belt 12 moved by rollers or rollers 10, to the drive of which a motor 14 is provided.

Quer über das Förderband 12 erstreckt sich ein Portal 16, an dessen Querbalken 18 ein Wagen 20 längst des Querbalkens 18 beweglich geführt ist. Zum Antrieb des Wagens ist ein Motor 22 vorgesehen, dessen Ritzel 24 mit einer Verzahnung des Wagens 20 kämmt.Transversely over the conveyor belt 12, a portal 16 extends to the crossbar 18, a carriage 20 has been long since the crossbar 18 movably guided. To drive the carriage, a motor 22 is provided, the pinion 24 meshes with a toothing of the carriage 20.

An dem Wagen 20 ist mittels eines nicht dargestellten Antriebs eine Konsole 26 in Richtung des Doppelpfeils (Figur 2b) senkrecht verschiebbar geführt, an deren Ende ein Druckkopf 28 befestigt ist, der beispielsweise in Art eines Druckkopfes aufgebaut ist, wie er in Tintenstrahldrucken bzw. Ink-Jet oder Bubble-Jet Druckern verwendet wird, wobei aus Farbdüsen des Druckkopfes Färbeflüssigkeitstropfen abspritzbar sind.On the carriage 20 is by means of a drive, not shown, a console 26 in the direction of the double arrow ( FIG. 2b ) guided vertically displaceably, at the end of a printhead 28 is fixed, which is constructed for example in the manner of a printhead, as used in ink-jet printing or ink-jet or bubble-jet printers, wherein from ink nozzles of the printhead Färbeflüssigkeitstropfen are abspritzbar.

Zur Erfassung der Position der Frontplatte 2, deren Kontur und Dicke sind Sensoren 30, 32 und 34 vorgesehen, wobei der Sensor 30 beispielsweise die Vorderkante die auf dem Förderband 12 bewegten Frontplatte 2 erfaßt, der Sensor 32 die Höhe der Frontplatte 2 erfaßt und der an dem Querbalken 18 angebrachte Sensor 34 die Seitenkante der Frontplatte 2 erfaßt.For detecting the position of the front panel 2, the contour and thickness sensors 30, 32 and 34 are provided, the sensor 30 detects, for example, the leading edge of the moving on the conveyor belt 12 front panel 2, the sensor 32 detects the height of the front panel 2 and the the transverse bar 18 mounted sensor 34 detects the side edge of the front panel 2.

Die Sensoren können optisch, mit Ultraschall oder sonstwie arbeiten und können zusätzlich beweglich angeordnet sein, so daß die gesamte Geometrie der Oberfläche der Frontplatte 2 jeweils erfaßt werden kann, bevor die Oberfläche in den Bereich unter dem Druckkopf 28 kommt.The sensors may be optically, ultrasonically or otherwise operated and may additionally be movably arranged so that the entire geometry of the surface of the faceplate 2 may be detected before the surface enters the area under the print head 28.

In den Figuren nicht eingezeichnet ist der Färbeflüssigkeitsvorrat und die Färbeflüssigkeitsbeschickung für den Druckkopf 28, die beispielsweise aus großen Vorratsbehältern erfolgen kann, die auf dem Wagen 20 abgeordnet sind.Not shown in the figures is the dyeing liquid supply and the dyeing liquor feed for the print head 28, which can be done, for example, from large storage containers, which are seconded on the carriage 20.

Zur Steuerung der Vorrichtung ist ein Steuergerät mit einem Computer 36, einer Tastatur 38 und einem Bildschirm 40 vorgesehen. Es versteht sich, daß zusätzlich ein Lautsprecher vorgesehen sein kann.To control the device, a control device with a computer 36, a keyboard 38 and a screen 40 is provided. It is understood that in addition a speaker can be provided.

An Eingänge 42 des Computers 36 sind die Sensoren 30, 32 und 34 angeschlossen; an Ausgänge 44 sind die Antriebe zur zweidimensionalen Bewegung (in Querrichtung des Förderbandes 12 und senkrecht zu dessen Oberfläche) für den Druckkopf 28, die Steuerleitungen zur Ansteuerung des Druckkopfes 28 und gegebenenfalls die Antriebe zur Bewegung einer oder mehrerer der Sensoren 30, 32 und 34 sowie der Antrieb 14 des Förderbandes 12 angeschlossen.At inputs 42 of the computer 36, the sensors 30, 32 and 34 are connected; at outputs 44 are the drives for two-dimensional movement (in the transverse direction of the conveyor belt 12 and perpendicular to its surface) for the print head 28, the control lines for driving the print head 28 and optionally the drives for moving one or more of the sensors 30, 32 and 34 as well the drive 14 of the conveyor belt 12 is connected.

Über einen weiteren Eingang 46 werden Daten eingegeben, die das Muster angeben, das von dem Druckkopf 28 erzeugt werden soll. Für die Ausbildung dieser Muster bestehen alle Freiheitsgrade, wobei die Muster durch Scannen von Bildvorlagen in digitaler Form erzeugt werden können, gespeichert werden können und dann durch entsprechende Ansteuerung des Druckkopfes 28 sowie dessen Bewegung relativ zur Frontplatte 2 in Verbindung mit der Steuerung des Antriebs 14 auf die Frontplatte 2 aufgebracht werden können. Bezüglich der Datenverarbeitung stehen alle modernen Technologien zur Verfügung, wie sie beispielsweise für heutige Fotodrucke üblich sind.Via another input 46, data indicating the pattern to be generated by the print head 28 is input. All degrees of freedom exist for the formation of these patterns wherein the patterns can be generated by scanning of image templates in digital form, can be stored and then by appropriate control of the print head 28 and its movement relative to the front plate 2 in conjunction with the control of the drive 14 can be applied to the front panel 2. In terms of data processing, all modern technologies are available, such as are customary for today's photo prints.

Aufbau und Arbeitsweise der einzelnen Element der Vorrichtung sind an sich bekannt und werden daher nicht erläutert.Structure and operation of the individual element of the device are known per se and are therefore not explained.

Eine auf dem Förderband 12 befindliche Frontplatte 2 wird von den Sensoren 30, 32 und 34 hinsichtlich ihrer Lage und Größe erkannt, so daß der Wagen 20 und der senkrechte Antrieb der Konsole 26 sowie der Druckkopf 28 von dem Computer 36 entsprechend den gerade wirksamen Musterdaten derart gesteuert werden, daß das erwünschte Muster ausgebildet wird. Wenn die gesamte Kontur der Frontplatte 2 erfaßt wird, geschieht dies derart, daß praktisch keine Färbeflüssigkeit auf das Förderband 12 aufgebracht wird und die Oberfläche der Frontplatte 2 auch in ihren Randbereichen vollständig bedruckt ist.A located on the conveyor belt 12 front panel 2 is detected by the sensors 30, 32 and 34 in terms of their position and size, so that the carriage 20 and the vertical drive of the console 26 and the print head 28 of the computer 36 according to the currently active pattern data such be controlled so that the desired pattern is formed. When the entire contour of the front panel 2 is detected, this is done so that virtually no dyeing liquid is applied to the conveyor belt 12 and the surface of the front panel 2 is completely printed in its edge regions.

Die beschriebene Vorrichtung kann in vielfältiger Weise abgeändert werden. Beispielsweise ist, wenn die Geometrie der jeweiligen Frontplatte bekannt ist und die Frontplatte 2 an einer jeweiligen Bezugsposition auf das Förderband 12 aufgelegt wird und in vorbestimmter Weise zum Förderband 12 ausgerichtet ist, nur erforderlich, die Vorderkante der Frontplatte 2 bzw. die Lage der Bezugsposition relativ zum Querbalken 18 zu erfassen, so daß der Aufwand für die Sensoren entsprechend vermindert werden kann. Die senkrechte Bewegbarkeit des Druckkopfes 28 ist erforderlich, da entsprechend den Spezifikationen des Druckkopfes 28 und der erzielbaren Musterfeinheit ein vorbestimmter Abstand zwischen den Farbdüsen des Druckkopfes 28 und der zu bedruckenden Oberfläche der Frontplatte 2 erforderlich ist.The device described can be modified in many ways. For example, when the geometry of the respective faceplate is known and the faceplate 2 is placed at a respective reference position on the conveyor belt 12 and aligned in a predetermined manner with the conveyor belt 12, only the front edge of the faceplate 2 or the position of the reference position is required to detect the crossbar 18, so that the cost of the sensors can be reduced accordingly. The vertical mobility of the print head 28 is required because a predetermined distance between the ink nozzles of the print head 28 and the surface to be printed on the front panel 2 is required in accordance with the specifications of the print head 28 and the achievable pattern fineness.

Der in Figur 2 dargestellte, einzige bewegliche Druckkopf mit mehreren Farbdüsen (nicht dargestellt) zum Abspritzen unterschiedlicher Färbeflüssigkeiten kann beispielsweise durch in Förderrichtung hintereinander angeordnete Düsenbalken ersetzt werden, die sich quer über das Förderband 12 erstrecken und jeweils eine Reihe von Farbdüsen aufweisen, die selektiv vom Computer 36 ansteuerbar sind. Die Düsen der einzelnen Düsenbalken verspritzen jeweils nur eine Farbe, so daß jede Musterfarbe mit drei hintereinander angeordneten Düsenbalken erzeugbar ist.The in FIG. 2 shown, single movable printhead with a plurality of ink nozzles (not shown) for spraying different Färbeflüssigkeiten can be replaced, for example, in the conveying direction successively arranged nozzle beam, which extend across the conveyor belt 12 and each having a series of ink nozzles, which are selectively controlled by the computer 36 , The nozzles of the individual nozzle bars spray each only one color, so that each pattern color can be generated with three nozzle bars arranged one behind the other.

Figur 3 zeigt ein vorteilhaftes Detail einer erforderlichenfalls zusätzlich vorhandenen Druckeinrichtung in perspektivischer Darstellung. Bei dieser Druckeinrichtung ist der Drukkcopf 28 an einem Träger 50 längsbeweglich in Richtung des Doppelpfeils geführt und ist der Träger 50 um eine zur Richtung des Doppelpfeils senkrechte Achse 52 schwenkbar. Zusätzlich kann der Träger 50 höhenverstellbar oder der Druckkopf 28 relativ zum Träger 50 höhenverstellbar sein. FIG. 3 shows an advantageous detail of an additionally necessary existing printing device in perspective view. In this printing device, the printing head 28 is guided longitudinally movably on a carrier 50 in the direction of the double arrow, and the carrier 50 is pivotable about an axis 52 perpendicular to the direction of the double arrow. In addition, the carrier 50 can be height-adjustable or the print head 28 can be adjusted in height relative to the carrier 50.

Mit, der Anordnung ist es, wie unmittelbar einsichtig, möglich, Seitenflächen der Frontplatte 2 zu bedrucken, auch wenn die Seitenflächen schräg zur Förderrichtung des Förderbandes 12 gerichtet sind. -With, the arrangement is, as immediately apparent, possible to print on side surfaces of the front panel 2, even if the side surfaces are directed obliquely to the conveying direction of the conveyor belt 12. -

Figur 4 zeigt weitere Details möglicher Ausbildungen der Druckeinrichtung. Druckköpfe 282 sind einer Konsole 262 mittels eines nicht dargestellten Antriebs derart schwenkbar, daß an der Frontplatte 22 ausgebildete Vorsprünge 54 bedruckt werden können. Die Konsole 262 kann zusätzlich in senkrechter Richtung verschiebbar sein und die Druckköpfe 282 können beispielsweise durch entsprechende Lagerung von Tragarmen 56 an der Konsole 262 um eine senkrechte Achse schwenkbar sein. Durch die damit geschaffenen kinematischen Möglichkeiten ist es möglich, die Vorsprünge 54 derart zu bedrucken, daß sich die Farbdüsen der Druckköpfe 282 jeweils in einem vorbestimmten Abstand von der Oberfläche und senkrecht zur Oberflächenrichtung gerichtet befmden, wodurch sich hochqualitative Muster ausbilden lassen. FIG. 4 shows further details of possible configurations of the printing device. Printheads 28 2 are a bracket 26 2 pivotally by means of a drive, not shown, that on the front panel 2 2 formed projections 54 can be printed. The bracket 26 2 may additionally be displaced in the vertical direction and the print heads 28 2 may be pivotable about a vertical axis, for example, by appropriate support brackets 56 on the bracket 26 2 . By thus created kinematic possibilities, it is possible to print the projections 54 such that the ink nozzles of the print heads 28 2 are each directed at a predetermined distance from the surface and perpendicular to the surface direction, which can form high-quality pattern.

Der in Figur 4 weiter dargestellte Druckkopf 283 ist insgesamt derart beweglich, daß die Seitenflächen der Frontplatte 22 bedruckbar sind.The in FIG. 4 further illustrated printhead 28 3 is generally movable so that the side surfaces of the front panel 2 2 can be printed.

Wie aus den bisherigen Zeichnungen unmittelbar ersichtlich, kann mit einem Druckkopf 28, der an einer senkrecht und in Querrichtung des Förderbandes 12 beweglichen Konsole 26 (Figur 2) um eine senkrechte und eine waagrechte Achse schwenkbar angeordnet ist, im Zusammenwirken mit einer Vorwärts- und einer Rückwärtsbewegung des Förderbandes 12 jede Oberflächenkontur einer Frontplatte 2 bedruckt werden, beispielsweise auch Betätigungsknöpfe 60, die gemäß Figur 5 an einer Frontplatte 2 vorgesehen sind.As can be seen directly from the previous drawings, with a print head 28, which on a perpendicular and in the transverse direction of the conveyor belt 12 movable console 26 (FIGS. FIG. 2 ) is arranged pivotably about a vertical and a horizontal axis, in cooperation with a forward and a backward movement of the conveyor belt 12, each surface contour of a front panel 2 are printed, for example, also operation buttons 60, according to FIG. 5 are provided on a front panel 2.

Figur 6 zeigt ein Beispiel eines Dekors bzw. Musters 62, das auf eine mit einer Maserung 4 versehene Oberfläche einer Frontplatte 2 aufgebracht ist. Die Maserung 4, die durch das Holz selbst gegeben sein kann und/oder ebenfalls durch Bedrucken aufgebracht ist, kann unterschiedlich betont werden, je nach homogener Kontrastfarbe, in der die Oberfläche bespritzt bzw. bedruckt ist, wobei im dargestellten Beispiel zusätzlich ein rechteckiger Rahmen als Dekor bzw. Muster aufgebracht ist. FIG. 6 shows an example of a decor or pattern 62 which is applied to a surface 4 provided with a grain of a front panel 2. The grain 4, which may be given by the wood itself and / or also applied by printing, can be emphasized differently, depending on the homogeneous contrasting color in which the surface is sprayed or printed, in the example shown in addition a rectangular frame as Decor or pattern is applied.

Figur 7 zeigt eine Frontplatte, die einen Grundkörper 62, beispielsweise aus Preßspan, aufweist, auf den ein Furnier 66 aus weichem bzw. saugfähigem Holz aufgebracht ist. Wenn auf diese Art einer saugfähigen Oberfläche Flüssigkeitströpfchen 66 aufgebracht werden, verlaufen diese ähnlich wie bei faserigem oder feuchtem Papier seitlich und fließen ineinander, wodurch optisch sehr gefällige Muster erzeugt werden können, wenn unterschiedlich gefärbte Flüssigkeitströpfchen 66 mit ihren Randbereichen ineinander laufen. FIG. 7 shows a front plate having a base body 62, for example of pressboard, on which a veneer 66 is applied from soft or absorbent wood. When liquid droplets 66 are applied in this type of absorbent surface, they flow laterally and flow into one another, similar to fibrous or wet paper, whereby optically very pleasing patterns can be produced when differently colored liquid droplets 66 run into one another with their edge regions.

Die Menge der Färbeflüssigkeiten der einzelnen Flüssigkeitströpfchen, die ineinander läuft, kann durch das Volumen der Flüssigkeitströpfchen und die Art der Oberfläche beeinflußt werden.The amount of dyeing liquids of the individual liquid droplets that run into one another can be influenced by the volume of the liquid droplets and the type of surface.

Figur 8 zeigt ein Beispiel, in dem durch entsprechende Bedruckung einzelner Frontplatten 210 bis 215 ein Gesamtmuster bzw. optischer Gesamteindruck erzeugt werden kann. FIG. 8 shows an example in which by appropriate printing of individual front panels 2 10 to 2 15 a total pattern or overall visual impression can be generated.

Gemäß Figur 9 können in einem Druclckopf 28 unterschiedliche, mit unterschiedlich gefärbter Färbeflüssigkeit beschickte Farbdüsen 701 bis 704 vorgesehen sein, wobei beispielsweise die Druckköpfe 701, 702 und 723 mit Farben beschickt werden, die in ihrer Addition Schwarz ergeben und der Drucklcopf 704 unmittelbar mit schwarz gefärbter Färbeflüssigkeit beschickt wird.According to FIG. 9 For example, the printing heads 70 1 , 70 2 and 72 3 can be charged with colors which in their addition yield black and the printing head 70 4 immediately. In a print head 28 different color nozzles 70 1 to 70 4 charged with differently colored dyeing liquid can be provided is charged with black colored dyeing liquid.

Figur 10 zeigt eine Ausführungsform eines Druckkopfes 72, der in sich vier verschiedene Druckköpfe A, B, C und X enthält, wobei die Druckköpfe A, B, C mit unterschiedlich gefärbten Färbeflüssigkeiten beschickt werden und der Druckkopf X mit einer Spülflüssigkeit beschickt wird. Die Druckköpfe A, B, C spritzen die jeweilige Färbeflüssigkeit in einen Zwischenbehälter 74, der mit einem Rührer 76 versehen ist, und aus dem ein weiterer Druckkopf 78 beschickt wird. FIG. 10 shows an embodiment of a printhead 72, which contains four different printheads A, B, C and X, wherein the printheads A, B, C are charged with differently colored dyeing liquids and the printhead X is charged with a rinsing liquid. The printheads A, B, C inject the respective dyeing liquid into an intermediate container 74, which is provided with a stirrer 76, and from which a further print head 78 is charged.

Mit dem zusammengesetzten Druckkopf 72 wird folgendes erreicht:With the assembled printhead 72, the following is achieved:

Durch entsprechende Ansteuerung der Druckköpfe A, B, C läßt sich in dem Zwischenbehälter 74 aus den drei unterschiedlichen Färbeflüssigkeiten jede Mischfarbe in programmierter Weise erzeugen, deren Homogenität durch den Rührer 76 gewährleistet wird. Aus dem Druckkopf 78 kann auf diese Weise Färbeflüssigkeit jeder gewünschten Farbe großflächig und homogen abgespritzt und auf eine Oberfläche aufgebracht werden.By appropriate control of the printheads A, B, C can be produced in the intermediate container 74 from the three different dyeing liquids each mixed color in a programmed manner, the homogeneity of which is ensured by the stirrer 76. In this way, dyeing liquid of any desired color can be sprayed off from the print head 78 over a large area and homogeneously and applied to a surface.

Figur 11 zeigt den Druckkopf 72 der Figur 10 bei einem Spülvorgang, wenn ein Farbwechsel erforderlich ist. Aus dem Druckkopf X wird in den Zwischenbehälter 74, nachdem dessen programmierte Flüssigkeitsvolumen weitgehend verspritzt ist, aus einem Vorratsbehälter 80 Spülflüssigkeit gespritzt, die in einem Kreislauf 82 geführt wird. Die Spülflüssigkeit kann bei 86, wenn die Färbeflüssigkeit pigmentierte Färbeflüssigkeit ist, gefiltert werden und den Zwischenbehälter 74 wiederholt durchströmen, bis keine Farbrückstände mehr vorhanden sind, und dann dem Vorratsbehälter 80 erneut zugeführt werden. Die Bezugszeichen 88 und 90 stellen Ventile dar, Bezugszeichen 92 bezeichnet eine Pumpe. Mit der Anordnung der Figur 11 können in umweltfreundlicher Weise und unter geringen Färbeflüssigkeitsverlusten unterschiedliche homogene Farben verspritzt werden. FIG. 11 shows the print head 72 of FIG. 10 during a rinse, when a color change is required. From the print head X is flushed into the intermediate container 74, after the programmed volume of liquid is largely sprayed, from a reservoir 80 rinsing liquid, which is guided in a circuit 82. The rinse liquid may be filtered at 86 when the dyeing liquor is pigmented dyeing liquor and repeatedly flow through the tundish 74 until there are no paint residues left and then returned to the reservoir 80. Reference numerals 88 and 90 represent valves, and reference numeral 92 denotes a pump. With the arrangement of FIG. 11 can be sprayed in an environmentally friendly manner and with low dyeing liquid losses different homogeneous colors.

Vorzugsweise wird der bisher geschilderten Bedruckung der Oberflächen der Frontplatten 2 eine Beschichtungsstufe nachgeschaltet, in der die mit Färbeflüssigkeit in einem vorbestimmten Muster und/oder mit einer vorbestimmten Hintergrundfarbe ausgebildete Oberfläche mit einer Schutzschicht versehen wird, indem diese Schutzschicht beispielsweise als Folie oder als Ein- oder Zweikamponenten-Kunstharzlack oder als Naturharzlack aufgebracht wird. Die Schutzschicht, die vorzugsweise transparent ist, macht die Oberfläche strapazieriähig, chemisch unempfindlich und kratzfest. Sie vermindert des weiteren die Anforderungen an die UV-Beständigkeit der verwendeten Färbeflüssigkeiten bzw. Tinten, mit denen die Bedrukkung erfolgt. Die Schutzschicht kann durch Spritzen, Rollen oder auch sonstige, an sich bekannte Weise ausgebildet werden.Preferably, the previously described printing the surfaces of the front panels 2 is followed by a coating stage in which the surface formed with dyeing liquid in a predetermined pattern and / or with a predetermined background color is provided with a protective layer by this protective layer, for example as a film or as a single or Two-pack synthetic resin varnish or applied as a natural resin varnish. The protective layer, which is preferably transparent, makes the surface hard-wearing, chemically resistant and scratch-resistant. It further reduces the UV resistance requirements of the dyeing fluids or inks used to effect the damage. The protective layer can be formed by spraying, rolling or otherwise known per se.

Die beschriebenen Verfahren können in vielfältiger Weise abgeändert werden. Die Bedrukkung muß nicht zwangsläufig nach dem Tintenstrahlverfahren erfolgen. Die Einfärbung und/oder Musterausbildung der Oberflächen kann mit jedweden anderen Verfahren folgen, das vorzugsweise programmierbar ist, so daß ein hohes Maß an Flexibilität gegeben ist.The described methods can be modified in many ways. The Bedrukkung does not necessarily have to be done by the ink jet method. The coloring and / or patterning the surfaces may be followed by any other method, which is preferably programmable, so as to provide a high degree of flexibility.

Figur 12 zeigt schematisch die Struktur eines gesamten Systems zum Herstellen von Gruppen von Frontplatten, die für eine Küche benötigt werden. FIG. 12 schematically shows the structure of an entire system for producing groups of front panels needed for a kitchen.

Bezugszeichen 100 bezeichnet den Bestelleingang, in dem auf unterschiedlichster Weise Bestellungen einer Küche eingehen. Eine bestellte Küche ist gekennzeichnet durch die Art und Anzahl ihrer Bauelemente, wie Schränke, Fächer, Elektrogeräte usw., die zur Sichtseite alle durch Frontplatten abgeschlossen sind, die ein spezifisches Dekor aufweisen, das sich beispielsweise durch das Oberflächenmaterial, die Grundfarbe und das Muster mit den jeweiligen Farben auszeichnet.Reference numeral 100 denotes the order entry, received in the most diverse orders of a kitchen. A kitchen ordered is characterized by the type and number of its components, such as cabinets, compartments, electrical appliances, etc., which are all closed to the visible side by front panels, which have a specific decor, for example, by the surface material, the base color and the pattern with the respective colors.

Auf Grund einer bestellten Küche wird im Bestelleingang 100 einer Gruppe von Frontplatten ein elektronisch verarbeitbarer Datensatz zusammengestellt, der die für eine bestellte Küche benötigt und hinsichtlich ihrer Oberflächenbeschaffenheit und Abmessungen zusammengestellt wird. Je nachdem, ob die benötigten Frontplatten in einem Lager 102 bereits fertig vorhanden sind oder in einer Zuschneideeinrichtung 104 mit den jeweiligen Maßen hergestellt werden müssen, geht der bestellte Datensatz durch das Lager 102 oder die Zuschneideeinrichtung 104.Due to an ordered kitchen, the order input 100 of a group of front panels is compiled into an electronically processable data set which is required for a kitchen ordered and compiled in terms of its surface finish and dimensions. Depending on whether the required front panels are already finished in a bearing 102 or have to be produced in a cutting device 104 with the respective dimensions, the ordered data set passes through the bearing 102 or the cutting device 104.

Der im Bestelleingang 100 zusammengestellte Datensatz wird einer mit elektronischer Datenverarbeitung arbeitender Steuereinrichtung 102 zugeführt.The data set compiled in the order input 100 is fed to a controller 102 which operates with electronic data processing.

In einem Materiallager 104 sind vorgefertigte Rohtafeln der benötigten Oberflächenvielfalt, beispielsweise Kunststöffplatten und/oder mit Holz furnierte Platten gelagert.In a material store 104 prefabricated blank sheets of the required surface variety, such as plastic backing plates and / or wood veneered panels are stored.

Dem Materiallager nachgeordnet ist eine Formbearbeitungseinrichtung 106, in der dem Materiallager 104 entnommene Rohtafeln mit an sich bekannten numerisch gesteuerten Schneideinnchtungen oder sonstigen spanend bearbeiteten Einrichtungen zerteilt und aus ihnen Formplatten bzw. Formteile mit vorbestimmten Abmessungen hergestellt werden können. Der Formbearbeitungseinrichtung 106 nachgeschaltet ist ein Formteillager 108, in dem besonders oft benötigte, vorgefertigte Formteile gelagert werden.Subordinate to the material store is a mold processing device 106, in which the material store 104 removed raw sheets with known per se numerically controlled Schneideinnchtungen or other machined devices divided and from them mold plates or moldings can be made with predetermined dimensions. Downstream of the mold processing device 106 is a molded part store 108, in which prefabricated molded parts which are required particularly often are stored.

Weiter ist der Formbearbeitungseinrichtung 106 eine Konfektioniereinrichtung 110 nachgeordnet, in der Gruppen von Formteilen, die beispielsweise zu einer Bestellung gehören, zusammengefaßt werden. Diese Gruppen können unter unterschiedlichen Gesichtspunkten geordnet werden, beispielsweise unmittelbar nach Bestellung oder danach, ob sie vorbestimmte spezielle Oberflächenbehandlungen erfordern, die erst nach Umrüstungen möglich sind. Zu einer Bestellung können unterschiedlichste Oberflächen gehören.Further, the form-processing device 106 is followed by a confectioning device 110, are summarized in the groups of molded parts, which belong for example to a purchase order. These groups can be classified from different perspectives, for example immediately after ordering or after, if they require predetermined special surface treatments that are possible only after retrofitting. An order can include a wide variety of surfaces.

Der Konfektioniereinrichtung 110 nachgeordnet ist eine Vorbehandlungseinrichtung 112, in der die in der Konfektioniereinrichtung zusammengestellten Formteile in vorbestimmter Wiese vorbehandelt werden, beispielsweise mit einer Grundierung versehen werden, ein Umleimer angebracht wird, ein Kantenschutz angebracht wird, usw..Downstream of the packaging device 110 is a pretreatment device 112, in which the molded parts assembled in the packaging device are pretreated in a predetermined manner, for example provided with a primer, a lipping is applied, edge protection is applied, etc.

Der Vorbehandlungseinrichtung 112 nachgeordnet ist eine Bedruckungseinrichtung 114, die beispielsweise ähnlich der anhand der vorstehenden Figuren erläuterten Bedruckungseinrichtung aufgebaut ist. An die Bedruckungseinrichtung 114 schließt sich eine Beschichtungseinrichtung 116 an, in der die bedruckten und gegebenenfalls wenig widerstandsfähigen Oberflächen beispielsweise mit Klarlack beschichtet werden, der mechanisch besonders widerstandsfähig ist, chemisch nicht angreifbar ist und/oder kein UV-Licht durchläßt. An die Beschichtungseinrichtung 116 schließt sich ein Warenausgang 118 an, in dem die fertigen Bauteile für ihre weitere Verarbeitung zu einer kompletten Küche, einem Möbelstück, usw. zur Verfügung stehen.Downstream of the pretreatment device 112 is a printing device 114, which is constructed, for example, similar to the printing device explained with reference to the preceding figures. The printing device 114 is followed by a coating device 116, in which the printed and possibly less resistant surfaces are coated, for example, with clearcoat, which is mechanically particularly resistant, chemically unaffected and / or does not transmit UV light. The coating device 116 is followed by a goods outlet 118, in which the finished components for their further processing into a complete kitchen, a piece of furniture, etc. are available.

In Figur 12 stellen Doppelpfeile den jeweiligen Materialfluß dar. Die Verbindungen zwischen der elektronischen Steuereinrichtung 102 und den einzelnen Stationen sind durch Striche angedeutet, wobei die Doppelpfeile jeweils darauf hindeuten, dass eine bidirektionale Datenkommunikation stattfindet.In FIG. 12 Double arrows represent the respective material flow. The connections between the electronic control device 102 and the individual stations are indicated by dashes, the double arrows each indicating that bidirectional data communication is taking place.

In den einzelnen Einrichtungen bzw. Stationen vorgesehene Handhabungseinrichtungen, Fördereinrichtungen, Regallager usw. können in ihrem Aufbau an sich bekannt sein und werden von der Steuereinrichtung 2 entsprechend dem jeweiligen Datensatz gesteuert.In the individual facilities or stations provided handling facilities, conveyors, racking, etc. may be known per se in their construction and are controlled by the control device 2 according to the respective data set.

Es sei angenommen, dass im Bestelleingang 100 ein einer bestellten Küche entsprechender Datensatz zusammengestellt wird. Die elektronische Steuereinrichtung fragt dann im Formteilelager 108 an, ob entsprechende Formteile bereits vorgefertigt sind. Die vorhandenen Formteile werden zur Konfektioniereinrichtung 110 geliefert. Die noch nicht vorgefertigten Formteile werden in der Formbearbeitungseinrichtung 106 aus den Rohtafeln bearbeitet und der Konfektioniereinrichtung 110 zugeführt. Anschließend durchlaufen die Bauteile die Vorhandlung, die Bedruckung und die Beschichtung, um dann im Warenausgang 118 zur Verfügung zu stehen. Die Vorbehandlungseinrichtung 112 und die Beschichtungseinrichtung 116 können grundsätzlich ähnlich wie die Bedruckungseinrichtung aufgebaut sein, d.h. ein Förderband oder eine sonstige Fördereinrichtung enthalten, auf dem sie der jeweiligen Bearbeitungsstation zugeführt werden, wobei ihre jeweilige Position, Geometrie usw. von Positionssensoren erfaßt wird.It is assumed that in the order input 100 a set kitchen corresponding record is compiled. The electronic control device then in the molded parts store 108 asks whether appropriate moldings are already prefabricated. The existing ones Shaped parts are supplied to the confectioning device 110. The not yet prefabricated molded parts are processed in the form-processing device 106 from the raw sheets and fed to the confectioning device 110. Subsequently, the components go through the process, the printing and the coating, in order to be available in the goods outlet 118. The pretreatment device 112 and the coating device 116 can in principle be constructed similar to the printing device, ie contain a conveyor or other conveyor on which they are fed to the respective processing station, with their respective position, geometry, etc. is detected by position sensors.

Wie sich aus dem Vorstehenden unmittelbar ergibt, ermöglicht das eründungsgemäße System bei geringster Lagerhaltung (Materiallager 104; das Formteilelager 108 ist nicht zwingend) eine bedarfsgerechte, vollautomatisierte oder, falls einzelne Handgriffe manuell erfolgen, weitgehend automatisierte Herstellung von Bauteilegruppen entsprechend einem Bestelleingang. Es versteht sich, dass sich an den Warenausgang 118 weitere vollautomatische Bearbeitungsstationen anschließen können, in denen aus den vorgefertigten, hinsichtlich ihrer Oberfläche fertigen Bauteilen komplette Möbelstücke zusammengebaut werden.As can be seen directly from the above, the system according to the invention with the least possible storage (material store 104; molded parts store 108 is not compulsory) enables a demand-driven, fully automated or, if individual manual operations take place manually, largely automated production of component groups corresponding to an order entry. It goes without saying that 118 more fully automatic processing stations can be connected to the goods outlet, in which complete pieces of furniture are assembled from the prefabricated components which are finished with respect to their surface.

Das beschriebene System kann in vielfältiger Weise abgeändert werden. Beispielsweise sind die Vorbehandlungseinrichtung 112 und die Beschichtungseinrichtung 116 nicht zwingend. Die Bedruckungseinrichtung 114 kann nach unterschiedlichen Verfahren arbeiten. An die Konfektioniereinrichtung 110 und/oder die Vorbehandlungseinrichtung 112 kann sich eine weitere Bearbeitungsstation anschließen, in der aus den noch nicht bedruckten Bauteilen zusammengesetzte Baugruppen hergestellt werden, die dann bedruckt werden. Die Formbearbeitungseinrichtung 106 kann in ihrem Aufbau komplex sein, so dass aus Rohtafeln nicht nur Bauteile zugeschnitten werden, sondern beispielsweise zusätzlich mit dreidimensionalen Ornamenten ausgebildet werden usw..The described system can be modified in many ways. For example, the pretreatment device 112 and the coating device 116 are not mandatory. The printing device 114 can operate according to different methods. The finishing device 110 and / or the pretreatment device 112 may be followed by a further processing station, in which assembled components are produced from the components which have not yet been printed, which are then printed. The shape processing device 106 may be complex in structure, so that not only components are cut from raw sheets, but for example, additionally formed with three-dimensional ornaments, etc. ..

Mit dem geschilderten System können auch Ersatzteile für Möbelstücke, beispielsweise Ersatzwände oder Fronttafeln einer Küche hergestellt werden, da das System durch die vorteilhafterweise programmierbare Bedruckung 114 und die gegebenenfalls Ergänzung durch die Vorbehandlung und die Beschichtung mit sehr guter Reproduzierbarkeit arbeitet. Das System ist außerordentlich flexibel und eignet sich bezüglich seines geschilderten strukturellen Aufbaus zum Einsatz für die Produktion, insbesondere jedwelcher Möbel. Das die einzelnen Stationen vernetzende EDV-System kann nach Aussehen hin beliebig vernetzt sein, beispielsweise mit räumlich weit entfernten Bestelleingängen über unterschiedlichste Kommunücationswege kommunizieren.The described system can also be used to produce spare parts for pieces of furniture, for example spare walls or front panels of a kitchen, since the system works by the advantageously programmable printing 114 and, if appropriate, supplementation by the pretreatment and the coating with very good reproducibility. The system is extremely flexible and suitable for its described structural design for use in the production, in particular of any furniture. That the individual stations Networking EDP system can be arbitrarily networked by appearance, for example, communicate with spatially distant order inputs on a variety of Kommunücationswege.
