Description

Bei der Herstellung von Platten fĆ¼r die Mƶbelproduktion werden hƤufig die Grundplatten aus Holz oder Holzwerkstoffen mit Dekorfolien oder -papieren belegt bzw. beschichtet, um eine hochwertige OberflƤche zu erhalten. Vorzugsweise werden bei diesen Verfahren zuerst die HauptoberflƤchen (Ober- und/oder Unterseite) und danach eine, mehrere oder alle Schmalseiten der Platten mit der Beschichtung versehen.In the production of panels for furniture production, the base plates made of wood or wood-based materials are often covered or coated with decorative films or papers in order to obtain a high-quality surface. Preferably, in these methods, first the main surfaces (top and / or bottom) and then one, several or all narrow sides of the plates are provided with the coating.

Bekannte Verfahren sehen hƤufig vor, die Mƶbelplatten in einem Durchlaufverfahren zu beschichten. Die Platten laufen auf Transportrollen und werden an einer Seite oder zwei gegenĆ¼berliegenden Seiten mit den Folien oder Dekorpapieren belegt. Diese Beschichtungsmaterialien weisen hƤufig eine Klebeschicht auf oder es wird ein Kleber auf die Haftseite der Beschichtungsmaterialien und/oder die zu beschichtende Seite der Platten aufgetragen. Nachfolgend werden die Beschichtungsmaterialien aufgebracht und an die PlattenoberflƤche angedrĆ¼ckt.Known methods often provide for coating the furniture panels in a continuous process. The plates run on transport rollers and are covered on one side or two opposite sides with the films or decor papers. These coating materials often have an adhesive layer or an adhesive is applied to the adhesive side of the coating materials and / or the side of the plates to be coated. Subsequently, the coating materials are applied and pressed against the plate surface.

Das AndrĆ¼cken erfolgt im Stand der Technik hƤufig mit einzeln federgelagerten Rollen oder Gleitschuhen.The pressing is done in the art often with individually spring-loaded rollers or sliding shoes.

In der DE 20 2006 020 669 U1 werden in den Figuren Fig. 9 bis Fig. 11 verschiedene Mƶglichkeiten dargestellt, um den Andruck des Beschichtungsmaterials auf der PlattenoberflƤche zu realisieren. Zum Einsatz kommen hier ein Andruckschuh (Fig.9), ein Rollenbandsystem (Fig. 10), bei dem ein umlaufendes Band an verschiedenen Zwischenpunkten gegen die PlattenoberflƤche gedrĆ¼ckt wird, sowie ein System von mehreren hintereinander angeordneten Andruckrollen (Fig. 11). Nachteilig an dem System nach Fig. 11 ist der komplexe Aufbau, der ein umlaufendes Band und dafĆ¼r in ihrer Lage zuverlƤssig stabile Rollen sowie einen Antrieb erfordert.In the DE 20 2006 020 669 U1 In FIGS. 9 to 11, various possibilities are shown in order to realize the pressure of the coating material on the plate surface. 9), a roller belt system (FIG. 10) in which a circulating belt is pressed against the disk surface at various intermediate points, and a system of a plurality of pinch rollers arranged behind one another (FIG. 11). A disadvantage of the system according to FIG. 11 is the complex structure which requires a circulating belt and, in its position, reliably stable rollers and a drive.

In der DE 10 2013 008 022 B3 wird eine Gleitschuhkonstruktion vorgeschlagen, die ein Federblech vorsieht, das mehrere, zur Bewegungsrichtung senkrechte oder geneigte rippenartige UnterstĆ¼tzungselemente aufweist, die die Kraftwirkung des Federelementes auf die zu bearbeitende FlƤche Ć¼ber die LƤnge des Federelementes hinweg stƤndig erneuern. Nachteilig an dieser Konstruktion, wie an allen Gleitschuhkonstruktionen, ist die groƟe Empfindlichkeit gegen Verschmutzungen. Ein auf der OberflƤche aufliegendes Partikel kann nicht nur in die OberflƤche eingedrĆ¼ckt, sondern Ć¼ber diese hinweggeschleift werden, was zu einem das Endprodukt entwertenden Kratzer fĆ¼hren kann.In the DE 10 2013 008 022 B3 a slipper construction is proposed, which provides a spring plate having a plurality of perpendicular to the direction or inclined rib-like support elements that constantly renew the force of the spring element on the surface to be machined over the length of the spring element. A disadvantage of this construction, as on all Gleitschuhkonstruktionen, is the high sensitivity to contamination. A particle lying on the surface can not only be pressed into the surface, but can be dragged over it, which can lead to a scratches that devalue the end product.

Versuche mit einzeln federgelagerten Andruckrollen, wie sie aus dem Stand der Technik bekannt sind, haben gezeigt, dass diese Rollen ebenfalls nur bedingt geeignet sind, OberflƤchen mit der gewĆ¼nschten GlƤtte zu erzielen. Unter UmstƤnden wird vor der Rolle eine Kleberwulst unter dem Beschichtungsmaterial angehƤuft, die beim Erreichen einer kritischen Klebermenge von der federgelagerten Rolle Ć¼berfahren und als Unebenheit der Beschichtung zurĆ¼ckgelassen wird.Experiments with individually spring-mounted pressure rollers, as known from the prior art, have shown that these roles are also only partially suitable to achieve surfaces with the desired smoothness. It may be before the role accumulated an adhesive bead under the coating material, which is run over on reaching a critical amount of adhesive from the spring-loaded roller and left as unevenness of the coating.

Es stellt sich somit die Aufgabe, eine Vorrichtung vorzuschlagen, die geeignet ist, die Nachteile des Standes der Technik zu Ć¼berwinden und Beschichtungsmaterial besonders glatt auf den Breit- und/oder Schmalseiten von Platten, insbesondere fĆ¼r Mƶbelplatten, aufzubringen. Auch die Ausformung der Kanten, die Breit- und Schmalseite verbinden, soll verbessert werden. Insbesondere wird eine GlƤttung bei mƶglichst geringer Beanspruchung des Beschichtungsmaterials angestrebtIt therefore sets itself the task of proposing a device which is suitable to overcome the disadvantages of the prior art and coating material particularly smooth on the broad and / or narrow sides of plates, especially for furniture panels apply. The shape of the edges that connect the broad and narrow sides should also be improved. In particular, a smoothing at the lowest possible stress of the coating material is desired

ErfindungsgemƤƟ wird die Aufgabe mit einer Vorrichtung nach Anspruch 1 gelƶst. Vorteilhafte AusfĆ¼hrungsformen sind in den rĆ¼ckbezogenen UnteransprĆ¼chen offenbart.According to the invention the object is achieved with a device according to claim 1. Advantageous embodiments are disclosed in the dependent claims.

Die erfindungsgemƤƟe Vorrichtung besteht aus einer Mehrzahl von Rollen, die in Durchlaufrichtung der zu beschichtenden Platte hintereinander, mit zueinander parallelen Achsen angeordnet sind. Erfindungswesentlich ist, dass diese Rollen in einem gemeinsamen Tragrahmen angeordnet sind, der zur GƤnze federgelagert ist. Die Rollen sind in dem Tragrahmen ohne Federlagerung, starr (jedoch rotierbar) gelagert. Durch die Anordnung der Rollen in einem gemeinsamen Tragrahmen wird die Konstruktion eines Andruckschuhs (flƤchige Wirkung) mit den Vorteilen des Rolleneinsatzes (keine Gleitreibung auf dem Material) kombiniert.The device according to the invention consists of a plurality of rollers, which are arranged one behind the other in the direction of passage of the plate to be coated, with mutually parallel axes. Essential to the invention is that these rollers are arranged in a common support frame, which is fully spring-loaded. The rollers are stored in the support frame without spring support, rigid (but rotatable). The arrangement of the rollers in a common support frame, the construction of a Andruckschuhs (area effect) with the advantages of the roller insert (no sliding friction on the material) is combined.

Der Tragrahmen wird Ć¼ber die Federlagerung gegen die zu bearbeitende OberflƤche gepresst. Die zu bearbeitende OberflƤche, bevorzugt die Breit- oder Schmalseite, aber auch die Kante, einer Mƶbelplatte, bewegt sich relativ zu dem Tragrahmen in Durchlaufrichtung. Die zu bearbeitende OberflƤche ist bevorzugt flach ("flach" abstrahiert hier von Unebenheiten in der fĆ¼r die Mƶbelplattenproduktion typischen OberflƤchenbeschaffenheit). Eine Bearbeitung der Kanten ist jedoch ebenfalls mƶglich. Die Vorrichtung ist nur in der AusfĆ¼hrungsform mit zwei Rollen zur Bearbeitung gekrĆ¼mmter OberflƤchen geeignet. Der Tragrahmen presst mittels der in ihm angeordneten Mehrzahl von Rollen das auf der OberflƤche zu befestigende (anzuleimende) Beschichtungsmaterial (bevorzugt Papier, PP- oder PVC-Folien, Melamin) gegen die PlattenoberflƤche bzw. -kante. Der zur Befestigung dienende Kleber wird dabei gesondert zugegeben oder ist bereits als Klebeschicht auf dem Beschichtungsmaterial vorhanden.The support frame is pressed against the surface to be treated via the spring support. The surface to be machined, preferably the broad or narrow side, but also the edge, a furniture panel moves relative to the support frame in the direction of passage. The surface to be worked on is preferably flat ("flat" here abstracts from unevenness in the surface texture typical of furniture board production). Editing the edges is also possible. The device is only suitable in the embodiment with two rollers for processing curved surfaces. By means of the plurality of rollers arranged in it, the carrier frame presses the coating material (preferably paper, PP or PVC films, melamine) to be fastened to the surface (preferably paper, PP or PVC films) against the plate surface or edge. The adhesive used for attachment is added separately or is already present as an adhesive layer on the coating material.

Bevorzugt ist der Tragrahmen als rechteckiges oder offenes Gestell realisiert, das die Lager fĆ¼r die Mehrzahl von Rollen trƤgt. Die Lager sind bevorzugt als kugelgelagerte Konstruktionen nach dem Stand der Technik ausgefĆ¼hrt. Sie sind fest in dem Tragrahmen angeordnet und weisen gegenĆ¼ber dem Tragrahmen keine Federung auf. Der Tragrahmen ist als starre Konstruktion ausgefĆ¼hrt und gestattet insbesondere keine VerƤnderung der Positionen der Lage der Rollen gegeneinander. Die Konstruktion des Tragrahmens ist nicht an die Form eines rechteckigen Gestells gebunden. Es sind auch andere AusfĆ¼hrungsformen denkbar, bspw. offene Profile, insbesondere die Anordnung aller Rollenlager in den SeitenwƤnden eines U-Profils bei Federlagerung des U-Profils. Wesentlich ist die Eignung der Vorrichtung fĆ¼r die gemeinsame Aufnahme der Rollenlager und die Federlagerung der Vorrichtung als Ganzes. Der Tragrahmen wird bevorzugt am Maschinengestell der DurchlaufstraƟe zur Produktion von Mƶbelplatten widergelagert. Der Fachmann ist in der Lage, den Tragrahmen in der erforderlichen Position (Arbeitsposition) zu justieren, so dass eine zu beschichtende Mƶbelplatte den Tragrahmen anfƤhrt und die erste Rolle als Einlaufzone nutzend unter den Tragrahmen bewegt wird. Der Tragrahmen wird dabei in die Federlagerung bewegt, die eine entsprechende Anpresskraft als Gegenkraft erzeugt.Preferably, the support frame is realized as a rectangular or open frame, which carries the bearings for the plurality of rollers. The bearings are preferably designed as ball-bearing constructions according to the prior art. They are firmly in the support frame arranged and have respect to the support frame no suspension. The support frame is designed as a rigid construction and allows in particular no change in the positions of the position of the rollers against each other. The construction of the support frame is not tied to the shape of a rectangular frame. There are also other embodiments conceivable, for example. Open profiles, in particular the arrangement of all roller bearings in the side walls of a U-profile with spring mounting of the U-profile. Essential is the suitability of the device for the joint recording of the roller bearings and the spring mounting of the device as a whole. The support frame is preferably mounted on the machine frame of the continuous line for the production of furniture panels. The skilled person is able to adjust the support frame in the required position (working position), so that a furniture panel to be coated anfƤhrt the support frame and the first role is used as an inlet zone under the support frame moves. The support frame is moved into the spring bearing, which generates a corresponding contact force as a counterforce.

Der Tragrahmen ist in seiner GƤnze federgelagert. Er ist dazu an bevorzugt drei oder vier, weiterhin bevorzugt sechs und darĆ¼ber hinaus bevorzugt acht Stellen federgelagert. Der Begriff "federgelagert" beschreibt hier, dass der Tragrahmen KrƤften, die senkrecht auf die durch die Mehrzahl von Rollen gebildete Ebene wirken, bis zu einem Anschlagspunkt ausweichen kann. Dem Fachmann ist bekannt, dass ein derartiges Verhalten nicht nur durch Federn sondern auch durch bspw. pneumatische Federung erreicht werden kann. Entsprechende Konstruktionen nach dem Stand der Technik werden unter dem Begriff "federgelagert" subsumiert, wobei die tatsƤchliche Lagerung vermittels Federn besonders bevorzugt ist. Der Tragrahmen ist bevorzugt in der NƤhe der Ecken federgelagert und, falls mehr als vier Federlagerungen zum Einsatz kommen, sind diese vorzugsweise zwischen den Lagern an den Ecken, an den Seiten verteilt, die die Rollenlager aufweisen. Optional ist es auch mƶglich, Federn an von den rollentragenden Seiten abweichenden Positionen, bspw. an den zu den Rollenachsen parallelen Seiten des Tragrahmens anzuordnen. Bevorzugt weisen die Federn gleiche Federkonstanten auf und sind somit geeignet, identische KrƤfte Ć¼ber den Tragrahmen und die Rollen auf die zu bearbeitende OberflƤche auszuĆ¼ben (symmetrische Kraftverteilung). FĆ¼r spezielle AnwendungsfƤlle kann es jedoch wĆ¼nschenswert sein, auf einer rollenlagertragenden Seite des Tragrahmens grĆ¶ĆŸere KrƤfte ausĆ¼ben zu kƶnnen, als auf der anderen (asymmetrische Kraftverteilung). In diesem Fall kƶnnen Federn mit je nach Seite, voneinander abweichenden Federkonstanten oder aber auch unterschiedliche Federanzahlen zum Einsatz kommen. Insbesondere ist die Federanordnung durch die angestrebte Kraftverteilung auf der zu bearbeitenden OberflƤche bestimmt und kann vom Fachmann berechnet werden. Auch die Anzahl von Federn, die letztendlich benƶtigt wird, kann so bestimmt werden und unter UmstƤnden von den oben genannten Werten abweichen. Bevorzugt ist die Richtung der Anpresskraft senkrecht (im Rahmen der Fertigungstoleranz) zur OberflƤche, die durch die Rollen bearbeitet werden soll. In AusfĆ¼hrungsformen, die fĆ¼r eine Kantenbearbeitung vorgesehen sind, kann die Kraftrichtung von der Senkrechten auf die Schmal- oder Breitseite abweichen.The support frame is spring-loaded in its entirety. He is feathered on preferably three or four, more preferably six and more preferably eight places. The term "spring-loaded" here describes that the support frame can act on forces acting perpendicular to the plane formed by the plurality of rollers, up to a stop point. It is known to the person skilled in the art that such a behavior can be achieved not only by springs but also by, for example, pneumatic suspension. Corresponding designs according to the prior art are subsumed under the term "spring-loaded", wherein the actual storage by means of springs is particularly preferred. The support frame is preferably spring-loaded in the vicinity of the corners and, if more than four spring bearings are used, they are preferably distributed between the bearings at the corners, on the sides having the roller bearings. Optionally, it is also possible to arrange springs at positions deviating from the roller-carrying sides, for example at the sides of the support frame which are parallel to the roller axes. Preferably, the springs have the same spring constants and are therefore suitable to exert identical forces on the support frame and the rollers on the surface to be machined (symmetrical force distribution). For special applications, however, it may be desirable to be able to exert greater forces on a roller bearing bearing side of the support frame than on the other (asymmetrical force distribution). In this case, springs can be used with different spring rates, depending on the side, divergent spring rates or different numbers of springs. In particular, the spring arrangement is determined by the desired force distribution on the surface to be processed and can be calculated by a person skilled in the art. Also, the number of springs that is ultimately needed can be determined and possibly from the above deviate from the stated values. Preferably, the direction of the contact force is perpendicular (within the manufacturing tolerance) to the surface to be processed by the rollers. In embodiments that are intended for edge processing, the direction of force may deviate from the vertical to the narrow or broad side.

Der Tragrahmen besteht bevorzugt aus Stahl oder einem Ƥhnlichen Material, das geeignet ist, die wirkenden KrƤfte zuverlƤssig aufzunehmen und dass die nƶtige Steifigkeit aufweist.The support frame is preferably made of steel or a similar material, which is adapted to reliably absorb the forces acting and that has the necessary rigidity.

Der Tragrahmen, genauer gesagt, die durch die Mehrzahl von Rollen gebildete Ebene, ist bevorzugt parallel zur zu bearbeitenden OberflƤche ausgerichtet. Die Rollen sind in einer ersten bevorzugten AusfĆ¼hrungsform zylindrisch und weisen eine glatte OberflƤche auf. Besonders bevorzugt besteht die OberflƤche der Rollen aus Stahl, Edelstahl oder ist verchromt. Weiterhin bevorzugt ist die OberflƤche der Rollen mit Teflon beschichtet.The support frame, more precisely, the plane formed by the plurality of rollers, is preferably aligned parallel to the surface to be machined. The rollers are cylindrical in a first preferred embodiment and have a smooth surface. Particularly preferably, the surface of the rollers made of steel, stainless steel or is chrome. Further preferably, the surface of the rollers is coated with Teflon.

Die Rollen der ersten bevorzugten AusfĆ¼hrungsform sind mindestens so lang, wie die Breite der zu bearbeitenden OberflƤche ist. Auf diese Weise wird ein kontinuierlicher Andruck Ć¼ber die gesamte zu bearbeitende OberflƤche erreicht. Optional kƶnnen die Rollen breiter sein, als die zu bearbeitende OberflƤche. Der Durchmesser der Rollen ist bevorzugt fĆ¼r alle Rollen identisch. Er entspricht den im Stand der Technik Ć¼blichen Abmessungen.The rollers of the first preferred embodiment are at least as long as the width of the surface to be processed. In this way, a continuous pressure over the entire surface to be machined is achieved. Optionally, the rolls may be wider than the surface to be worked. The diameter of the rollers is preferably identical for all roles. It corresponds to the dimensions customary in the prior art.

Bevorzugt ist der Tragrahmen fĆ¼r die erste bevorzugte AusfĆ¼hrungsform so zur zu bearbeitenden OberflƤche ausgerichtet, dass die Rollenachsen senkrecht zur Durchlaufrichtung der zu bearbeitenden OberflƤche ausgerichtet sind.Preferably, the support frame for the first preferred embodiment is oriented to the surface to be machined, that the roller axes are aligned perpendicular to the passage direction of the surface to be machined.

In einer weiterhin bevorzugten AusfĆ¼hrungsform sind die Rollenachsen gegen die Durchlaufrichtung geneigt. Dies wird bevorzugt erreicht, indem der Tragrahmen entsprechend gegen die Durchlaufrichtung geneigt wird. Die Neigung der Rollenachsen gegen die Senkrechte auf die Durchlaufrichtung in der Ebene der zu bearbeitenden OberflƤche ist bevorzugt kleiner als 10Ā°, besonders bevorzugt kleiner als 5Ā° und liegt ganz besonders bevorzugt im Bereich von 0,5Ā° bis 3Ā°.In a further preferred embodiment, the roller axes are inclined against the passage direction. This is preferably achieved by the support frame is inclined accordingly against the passage direction. The inclination of the roller axes against the perpendicular to the passage direction in the plane of the surface to be processed is preferably less than 10 Ā°, more preferably less than 5 Ā°, and most preferably in the range of 0.5 Ā° to 3 Ā°.

In einer zweiten bevorzugten AusfĆ¼hrungsform sind die Rollen tailliert und weisen im Querschnitt entlang der Rotationsachse annƤhernd die Form einer Sanduhr auf. Allgemeiner formuliert, sind die taillierten Rollen als zwei mit DeckflƤchen aufeinanderliegende KreiskegelstĆ¼mpfe ausgebildet. Dabei liegt der zweite Kreiskegelstumpf auf der kleineren DeckflƤche des ersten auf. Die DeckflƤchen (GrundflƤche und gegenĆ¼berliegende DeckflƤche) des ersten Kreiskegelstumpfs weisen nicht denselben Durchmesser auf. Die DeckflƤchen der KreiskegelstĆ¼mpfe verlaufen senkrecht zur Rotationsachse der jeweiligen Rolle. Die Hƶhen der KegelstĆ¼mpfe einer Rolle kƶnnen voneinander abweichen. Die MantelflƤche des ersten Kegelstumpfes rollt auf der zu bearbeitenden OberflƤche ab, wobei die Kante zu einer benachbarten OberflƤche in der Taillierung, der Aufsetzlinie des zweiten Kreiskegelstumpfes, abrollt. Die Hƶhe entlang der MantelflƤche des ersten Kreiskegelstumpfes entspricht dabei vorzugsweise mindestens der Hƶhe der zu bearbeitenden OberflƤche (vorzugsweise der Schmalseite der Mƶbelplatte). Auf diese Weise wird die zu bearbeitende OberflƤche vorteilhaft in ihrer gesamten Hƶhe bearbeitet. Der Kontakt der geneigten MantelflƤchen der ersten KreiskegelstĆ¼mpfe zur zu bearbeitenden OberflƤche wird erreicht, indem die Achsen der Rollen senkrecht im Tragrahmen verlaufen, der Tragrahmen als Ganzes jedoch gegen die Ebene der zu bearbeitenden OberflƤche geneigt ist.In a second preferred embodiment, the rollers are waisted and have approximately the shape of an hourglass in cross section along the axis of rotation. More generally, the waisted rollers are formed as two circular truncated cones superposed on top surfaces. In this case, the second circular truncated cone rests on the smaller top surface of the first. The top surfaces (base and opposite top surface) of the first circular truncated cone do not have the same diameter. The top surfaces of the circular truncated cones run perpendicular to the axis of rotation of the respective roller. The heights of the truncated cones of a roller may differ. The lateral surface of the first truncated cone rolls on the surface to be machined, wherein the edge rolls to an adjacent surface in the sidecut, the landing line of the second circular truncated cone. The height along the lateral surface of the first circular truncated cone preferably corresponds at least to the height of the surface to be machined (preferably the narrow side of the furniture panel). In this way, the surface to be processed is advantageously processed in its entire height. The contact of the inclined lateral surfaces of the first circular truncated cones to the surface to be machined is achieved by the axes of the rollers extending vertically in the support frame, but the support frame as a whole is inclined against the plane of the surface to be machined.

Alternativ kƶnnen die Achsen der Rollen im Tragrahmen so geneigt sein, dass der vollflƤchige Kontakt der OberflƤche mit den abrollenden MantelflƤchen der ersten KreiskegelstĆ¼mpfe hergestellt wird.Alternatively, the axes of the rollers in the support frame can be inclined so that the full-surface contact of the surface is made with the rolling lateral surfaces of the first circular truncated stumps.

Der Winkel der MantelflƤche des zweiten Kreiskegelstumpfes zu der des ersten Kreiskegelstumpfes betrƤgt mehr als 90Ā°. Die Hƶhe des zweiten Kreiskegelstumpfes kann deutlich geringer als die des ersten Kreiskegelstumpfes gewƤhlt werden, da dessen Hauptfunktion in der Bearbeitung der Kante liegt. In jedem Falle sollte die Hƶhe des zweiten Kreiskegelstumpfes jedoch die Kante Ć¼berragen.The angle of the lateral surface of the second circular truncated cone to that of the first circular truncated cone is more than 90 Ā°. The height of the second circular truncated cone can be chosen to be significantly smaller than that of the first circular truncated cone, since its main function is the processing of the edge. In any case, however, the height of the second circular truncated cone should project beyond the edge.

Bei mehreren hintereinander angeordneten Rollen sind die Neigungen der MantelflƤchen der ersten KreiskegelstĆ¼mpfe zur GrundflƤche konstant. Auch die Hƶhen sind identisch. Der Tragrahmen der Rollen ist so gegen die zu bearbeitenden OberflƤche geneigt, dass die MantelflƤchen der ersten KreiskegelstĆ¼mpfe auf dieser vollflƤchig abrollen kƶnnen. Der Neigungswinkel des Tragrahmens gegen die zu bearbeitende OberflƤche entspricht daher der Differenz von 90Ā° und der Neigung der MantelflƤchen der ersten KreiskegelstĆ¼mpfe zu deren GrundflƤchen. Die Neigungen der MantelflƤchen der zweiten KreiskegelstĆ¼mpfe zu deren GrundflƤchen nehmen vorzugsweise in Vorschubrichtung der Mƶbelplatten zu. Dementsprechend wird der eingeschlossene Winkel zwischen den MantelflƤchen der beiden KreiskegelstĆ¼mpfe kleiner. Dies beeinflusst die Ausformung der Kante zwischen OberflƤche und SchmalflƤche positiv.With several successively arranged rollers, the inclinations of the lateral surfaces of the first circular truncated cones to the base surface are constant. The heights are identical as well. The support frame of the rollers is inclined so against the surface to be machined that the lateral surfaces of the first circular truncated stumps can roll over this entire surface. The angle of inclination of the support frame against the surface to be machined therefore corresponds to the difference of 90 Ā° and the inclination of the lateral surfaces of the first circular truncated cones to the base surfaces. The inclinations of the lateral surfaces of the second circular truncated cones to the base surfaces preferably increase in the feed direction of the furniture panels. Accordingly, the included angle between the lateral surfaces of the two circular truncated stumps is smaller. This positively influences the shape of the edge between the surface and the narrow surface.

Der eingeschlossene Winkel zwischen den MantelflƤchen der beiden KreiskegelstĆ¼mpfe betrƤgt an der Einlaufrolle, d.h. der ersten Rolle eines Rollenschuhs, die die Mƶbelplatte erreicht, bevorzugt zwischen 175Ā° und 110Ā°, besonders bevorzugt zwischen 170Ā° und 120Ā° und ganz besonders bevorzugt zwischen 150Ā° und 125Ā°, an der Auslaufrolle, d.h. der letzten Rolle eines Rollenschuhs, die die Mƶbelplatte erreicht, bevorzugt zwischen 119Ā° und 92Ā°. Die eingeschlossenen Winkel der Rollen zwischen Einlauf- und Auslaufrolle liegen zwischen denen dieser beiden Rollen. Der Ɯbergangsbereich zwischen den beiden KreiskegelstĆ¼mpfen ist bevorzugt als Rundung mit geringem Radius ausgefĆ¼hrt. Der Radius betrƤgt bevorzugt zwischen 0,1 mm und 3 mm, besonders bevorzugt zwischen 0,3 mm und 2,5 mm und ganz besonders bevorzugt zwischen 0,5 mm und 2 mm. Als besonders geeignet hat sich ein Radius von 1 mm erwiesen.The included angle between the lateral surfaces of the two circular truncated cones is at the inlet roller, ie the first roller of a roller shoe, which reaches the furniture panel, preferably between 175 Ā° and 110 Ā°, more preferably between 170 Ā° and 120 Ā° and most preferably between 150 Ā° and 125 Ā°, at the outlet roller, ie the last role of a roller shoe that reaches the furniture panel, preferably between 119 Ā° and 92 Ā°. The included angle of the rollers between the inlet and outlet rollers are between those of these two roles. The transition area between the two Circular truncated cones is preferably designed as a rounding with a small radius. The radius is preferably between 0.1 mm and 3 mm, more preferably between 0.3 mm and 2.5 mm and most preferably between 0.5 mm and 2 mm. A radius of 1 mm has proven particularly suitable.

Der Anstieg der MantelflƤche des ersten Kreiskegelstumpfes gegenĆ¼ber seiner GrundflƤche (bzw. einer FlƤche senkrecht zur Rotationsachse der Rolle) betrƤgt bevorzugt zwischen 5Ā° und 70Ā°, besonders bevorzugt, zwischen 15Ā° und 60Ā° und ganz besonders bevorzugt zwischen 30Ā° und 60Ā°. Zu beachten ist, dass die Winkel so gewƤhlt werden, dass die angestrebten Kreiskegelhƶhen und Bearbeitungsgeometrien erreicht werden. Dem liegen einfache geometrische Ɯberlegungen zu Grunde, die dem Fachmann gelƤufig sind.The rise of the lateral surface of the first circular truncated cone relative to its base (or a surface perpendicular to the axis of rotation of the roller) is preferably between 5 Ā° and 70 Ā°, more preferably between 15 Ā° and 60 Ā° and most preferably between 30 Ā° and 60 Ā°. It should be noted that the angles are selected so that the desired circular bevel heights and machining geometries are achieved. This is based on simple geometric considerations which are familiar to the person skilled in the art.

Der Tragrahmen weist bevorzugt zwei, drei und besonders bevorzugt vier Rollen auf. Weiterhin bevorzugt sind fĆ¼nf oder sechs Rollen. Die tatsƤchlich eingesetzte Zahl von Rollen hƤngt von den technischen Anforderungen ab und kann die genannten Zahlen auch Ć¼bersteigen. Insbesondere weist der Tragrahmen jedoch stets mindestens drei Rollen auf. Untersuchungen haben gezeigt, dass vier Rollen in einem Tragrahmen ein besonders gutes GlƤttungsergebnis erzielen.The support frame preferably has two, three and more preferably four rollers. Further preferred are five or six rollers. The number of rolls actually used depends on the technical requirements and may exceed the figures mentioned above. In particular, however, the support frame always has at least three rollers. Investigations have shown that four rollers in a support frame achieve a particularly good smoothing result.

Optional kƶnnen mehrere erfindungsgemƤƟe Vorrichtungen in Durchlaufrichtung hintereinander angeordnet sein. Optional kƶnnen diese dabei auch unterschiedliche Neigungen der Tragrahmen, und damit der jeweiligen Rollen, gegen die Durchlaufrichtung realisieren.Optionally, a plurality of devices according to the invention can be arranged one behind the other in the direction of passage. Optionally, these can also realize different inclinations of the support frame, and thus the respective rollers, against the passage direction.

Die erfindungsgemƤƟe Konstruktion erreicht Ć¼berraschend sehr viel bessere GlƤttungsergebnisse, als sie mit einzeln federgelagerten Rollen erzielbar sind. Aufgrund der erfindungsgemƤƟen Konstruktion wird der Vorteil eines Gleitschuhs, die OberflƤche groƟflƤchig zu pressen, mit den Vorteilen des Rollenpressens, eine schonende OberflƤchenbehandlung zu gewƤhrleisten, verbunden.The construction according to the invention surprisingly achieves much better smoothing results than can be achieved with individually spring-loaded rollers. Due to the construction according to the invention, the advantage of a sliding shoe to press the surface over a large area, with the advantages of roller pressing to ensure a gentle surface treatment, connected.

Durch die zueinander starre Positionierung der Rollen im Tragrahmen, entfƤllt vorteilhaft eine aufwendige Justierung der Rollen zueinander. Lediglich der Tragrahmen wird beim Einbau justiert, wobei hier geringe Abweichungen von der ParallelitƤt des Tragrahmens zu der zu bearbeitenden OberflƤche durch die Federlagerung ausgeglichen werden.By mutually rigid positioning of the rollers in the support frame, advantageously eliminates a complicated adjustment of the rollers to each other. Only the support frame is adjusted during installation, in which case small deviations from the parallelism of the support frame to the surface to be machined are compensated by the spring bearing.

Die Achsen 22 der Rollen 2 sind voneinander 4 cm entfernt. Die Rollen sind gemeinsam in dem Tragrahmen 3 gelagert, so dass die Lage der Achsen 22 der Rollen 2 zueinander starr ist. Der gemeinsame Tragrahmen 3 besteht aus Edelstahl und ist an drei Punkten federgelagert. Die Federlagerungen sind in Durchlaufrichtung hintereinander angeordnet. Der Tragrahmen 3 ist um 15Ā° so gegen die Ebene, die durch die SchmalflƤche der Mƶbelplatte 1 verlƤuft geneigt, dass die MantelflƤchen der ersten KreiskegelstĆ¼mpfe K11, K21, K31 Ć¼ber die gesamte Hƶhe der SchmalflƤche mit der OberflƤche der SchmalflƤche in Eingriff stehen. Durch die Federkraft F wird ein Andruck gegen die SchmalflƤche realisiert. Die obere Kante der Mƶbelplatte verlƤuft direkt in den Radien R1, R2 und R3. Sie wird so vorteilhaft ebenfalls geglƤttet.The axes 22 of the rollers 2 are 4 cm apart. The rollers are mounted together in the support frame 3, so that the position of the axes 22 of the rollers 2 to each other is rigid. The common support frame 3 is made of stainless steel and is spring-loaded at three points. The spring bearings are arranged one behind the other in the direction of passage. The support frame 3 is 15 Ā° inclined to the plane passing through the narrow surface of the furniture panel 1 that the lateral surfaces of the first circular truncated cones K11, K21, K31 over the entire height of the narrow surface with the surface of the narrow surface engage. By the spring force F a pressure against the narrow surface is realized. The upper edge of the furniture panel runs directly in the radii R1, R2 and R3. It is also smoothed out so beneficial.

Alle Rollen 2 bestehen aus Werkzeugstahl mit einer verchromten OberflƤche. Nach dem Durchlauf der Mƶbelplatte 1 durch die erfindungsgemƤƟe Vorrichtung sind optionale weitere Vorrichtungen zur Schmalseitenbehandlung vorgesehen, die nicht Gegenstand der vorliegenden Erfindung sind.All rollers 2 are made of tool steel with a chrome finish. After passing through the furniture panel 1 by the device according to the invention optional additional devices for narrow side treatment are provided, which are not the subject of the present invention.
