Description

Die Erfindung betrifft ein Verfahren zur Kantenbearbeitung im Durchlauf einer mit einem Kantenband beschichteten Platte, vorzugsweise einer Möbelplatte gemäß dem Oberbegriff des Anspruchs 1 sowie eine Vorrichtung zur Durchführung des Verfahrens.The invention relates to a method for edge processing in the passage of a panel coated with an edge tape, preferably a furniture panel, and an apparatus for carrying out the method.

Insbesondere Möbelplatten aus Holz oder einem Holzwerkstoff werden kantenseitig mit einem sogenannten Kantenband beschichtet, um die üblicher Weise ober- und unterseitig bereits mit einer Dekorschicht versehenen Platte zu komplettieren und so einerseits einen für den Betrachter gefälligen Gesamteindruck und andererseits einen Schutz des Kerns der Platte vor äußeren Einflüssen zu schaffen.In particular, furniture panels made of wood or a wood-based material are edge-coated with a so-called edging tape in order to complete the usual way with a panel that has already been provided with a decorative layer on the top and bottom, thus giving the viewer a pleasing overall impression and protecting the core of the panel from outside To create influences.

Dabei kommen vermehrt Kantenbänder aus polierfähigem Kunststoff, wie Acryl oder dergleichen zum Einsatz, die durch thermische Behandlung zumindest einseitig klebfähig sind, wobei die Erwärmung beispielsweise mittels Laser- oder Plasmastrahlen erfolgt.Edge strips made of polishable plastic, such as acrylic or the like, are increasingly being used, which are at least one-sidedly adhesive by thermal treatment, the heating taking place, for example, by means of laser or plasma beams.

Zur Berücksichtigung von Dickentoleranzen der Platte, d. h., um eine vollständige Abdeckung der Plattenkante zu gewährleisten, ist das Kantenband so ausgelegt, dass ober- und/oder unterseitig nach dem Ankleben ein gewisser Überstand verbleibt, der in einem folgenden Arbeitsschritt abgetragen wird. Hierzu kommen geeignete Spanwerkzeuge, wie Fräser, Ziehklingen oder dergleichen zum Einsatz.To account for plate thickness tolerances, i.e. that is, in order to ensure complete coverage of the plate edge, the edge band is designed in such a way that a certain protrusion remains on the top and / or underside, which is removed in a subsequent work step. Suitable chip tools such as milling cutters, scraper blades or the like are used for this.

Allerdings erfährt das Kantenband bei diesem spanenden Abtrag eine sozusagen Oberflächenbeschädigung durch eine gegenüber der unbearbeiteten Oberfläche größere Rauhigkeit, mit der Folge, dass diese Oberfläche gegenüber der unbearbeiteten, hochglänzend erscheinenden sich stumpf, im Sinne von matt darstellt. Insbesondere aus gestalterischen Gründen stellt dies einen erkennbaren Mangel dar, der die optische Wertigkeit der gesamten Möbelplatte herab setzt.However, the edge band experiences a kind of surface damage during this cutting removal due to a greater roughness compared to the unprocessed surface, with the result that this surface is dull compared to the unprocessed, high-gloss surface, in the sense of matt. This is a noticeable defect, particularly for design reasons, which reduces the visual value of the entire furniture panel.

Um hier Abhilfe zu schaffen, wird in der DE 20 2005 002 637 U1 der Einsatz eines Polierwerkzeuges vorgeschlagen, auf das ein zähflüssiges oder pastöses Poliermittel aufgetragen wird.To remedy this, the DE 20 2005 002 637 U1 proposed the use of a polishing tool on which a viscous or pasty polishing agent is applied.

Jedoch hat sich die Konsistenz dieses Pollermittels als nachteilig, insbesondere hinsichtlich des Betriebs der Gesamtvorrichtung herausgestellt, da das auf das rotierende Polierwerkzeug aufgetragene Poliermittel unkontrolliert in den Raum geschleudert wird, wodurch sich eine nicht unerhebliche Verschmutzung der Bearbeitungsmaschine insgesamt, zumindest aber in dem Umgebungsbereich des Polierwerkzeuges ergibt. Naturgemäß steht dieser Umstand einem optimalen Betriebsablauf entgegen, da vor allem die am Fertigungsprozess beteiligten Aggregate durch Verschmutzung in Mitleidenschaft gezogen werden und es auf Grund dessen zu häufigen Betriebsunterbrechungen kommt.However, the consistency of this bollard has proven to be disadvantageous, particularly with regard to the operation of the overall device, since the polishing agent applied to the rotating polishing tool is thrown into the room in an uncontrolled manner, which results in a not inconsiderable contamination of the processing machine as a whole, or at least in the area surrounding the polishing tool results. Naturally, this stands in the way of an optimal operating process, since the units involved in the manufacturing process are particularly affected by contamination and this leads to frequent business interruptions.

Aus der CN 101 434 052 A ist ein Verfahren zum Polieren der Oberflächen harter Materialien wie Metall oder Keramik bekannt, bei dem formstabiles Wachs gegen eine Polierscheibe gedrückt wird.From the CN 101 434 052 A is known a method for polishing the surfaces of hard materials such as metal or ceramic, in which dimensionally stable wax is pressed against a polishing pad.

Ein vergleichbarer Stand der Technik ist in der JP 4 087 658 A offenbart, in der vorgeschlagen wird, zum Polieren eines Werkstücks Polierscheiben über ein formstabiles Wachs zu führen.A comparable prior art is in the JP 4 087 658 A discloses in which it is proposed to guide polishing discs over a dimensionally stable wax for polishing a workpiece.

In der US 3 833 346 A schließlich ist eine Vorrichtung beschrieben, bei der ein formstabiler Wachs gegen die Oberfläche eines Bandes gepresst wird.In the US 3,833,346 A finally, a device is described in which a dimensionally stable wax is pressed against the surface of a band.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren und eine Vorrichtung der gattungsgemäßen Art so weiter zu entwickeln, dass mit geringem konstruktiven und fertigungstechnischen Aufwand eine Optimierung des Betriebsablaufs, insbesondere hinsichtlich einer Bearbeitung des Kantenbands möglich ist.The invention is based on the object of further developing a method and a device of the generic type in such a way that an optimization of the operational sequence, in particular with regard to processing of the edge band, is possible with little constructional and manufacturing expenditure.

Diese Aufgabe wird durch ein Verfahren mit den Merkmalen des Anspruchs 1 bzw. eine Vorrichtung mit den Merkmalen des Anspruchs 4 gelöst.This object is achieved by a method with the features of claim 1 and a device with the features of claim 4.

Durch die Erfindung, die die automatische Beaufschlagung des Polierwerkzeuges, beispielsweise eines Polierbandes, einer rotierenden Polierbürste oder - scheibe, mit z.B. Hartwachs vorsieht, wird eine Verschmutzung des Arbeitsbereiches ausgeschlossen.By the invention, which the automatic loading of the polishing tool, for example a polishing belt, a rotating polishing brush or disk, with e.g. Hard wax provides, soiling of the work area is excluded.

Die zuvor beschriebenen Nachteile, die sich aus einer Verschmutzung ergeben, werden dadurch vermieden, sodass sich die Standzeit der Vorrichtung insgesamt erhöht. Dies führt in der Konsequenz zu einer durchaus bemerkenswerten Minimierung der Betriebskosten.The disadvantages described above, which result from contamination, are thereby avoided, so that the service life of the device is increased overall. As a consequence, this leads to a remarkable minimization of operating costs.

Nach der Erfindung wird die Poliermasse intermittierend auf das Polierwerkzeug aufgetragen. Dazu weist die Haltevorrichtung eine entsprechende Nach-stelleinrichtung auf, mit der im Übrigen die beispielsweise in Blockform vorliegende Poliermasse mit einem derartigen Druck am Polierwerkzeug anliegt, dass ein Abtrag auf das Polierwerkzeug gewährleistet ist.According to the invention, the polishing compound is applied intermittently to the polishing tool. For this purpose, the holding device has a corresponding adjusting device, with which the polishing compound, for example, which is in block form, rests against the polishing tool with a pressure such that removal on the polishing tool is ensured.

Wie sich überraschend gezeigt hat, wird durch das Polieren vor allem mittels Hartwachs eine hochglänzende Oberfläche erreicht, die, wie beschrieben, zuvor durch die spangebende Bearbeitung matt erschienen ist. Insoweit entspricht die nun glänzende Oberfläche der bearbeiteten Kante der der unbearbeiteten Oberfläche, die quasi die Breitseite des Kantenbandes sichtseitig bildet.As has surprisingly been shown, a high-gloss surface is achieved by polishing, especially with hard wax, which, as described, previously appeared matt due to the machining. In this respect, the now shiny surface of the processed edge corresponds to that of the unprocessed surface, which forms the broad side of the edge band on the visible side.

Prinzipiell kann im Bedarfsfall jedoch auch diese freie Fläche poliert werden, wozu eine weitere Haltevorrichtung vorgesehen ist, die in Korrespondenz mit einem dazu positionierten Polierwerkzeug steht.In principle, however, this free surface can also be polished if necessary, for which purpose a further holding device is provided which is in correspondence with a polishing tool positioned therefor.

Die zum Einsatz kommenden Kantenbänder, die gemäß der Erfindung bearbeitet werden, bestehen aus Acrylglas (PMMA) einem thermoplastischen Kunststoff, zum Beispiel Polyethylenterephthalat (PET) oder aus Polykarbonat.The edge bands used, which are processed according to the invention, consist of acrylic glass (PMMA), a thermoplastic material, for example polyethylene terephthalate (PET) or polycarbonate.

Neben dem genannten Hartwachs sind selbstverständlich auch andere formstabile Poliermassen denkbar, wenn sie denn zum gleichen Ergebnis führen, nämlich zur Schaffung einer hochglänzenden Oberfläche der bearbeiteten Bereiche.In addition to the hard wax mentioned, other dimensionally stable polishing compounds are of course also conceivable if they lead to the same result, namely to create a high-gloss surface on the processed areas.

Die Erfindung sieht vor, dass in Durchlaufrichtung der Platte vor dem Angriff des Polierwerkzeuges, der jeweils spanend bearbeiteten Kante zugeordnet, eine Lamellenbürste, bestehend aus abwechselnd Tuch- und Sisal-Lamellen, angreift, wobei die Sisal-Lamellen insbesondere zur Bearbeitung eines durch die spanende Bearbeitung hergestellten Radius, der einen fließenden Übergang von der Plattenoberfläche zur Breitseite des Kantenbandes darstellt.The invention provides that in the direction of passage of the plate before the attack of the polishing tool, which is assigned to the machined edge, a lamellar brush, consisting of alternating cloth and sisal lamellas, engages, the sisal lamellae in particular for machining a cutting Machined radius, which represents a smooth transition from the plate surface to the broad side of the edge band.

Bevorzugt rotiert die Lamellenbürste mit einer Umdrehungszahl von 1400 min-1 und ebenso wie die nachfolgenden Polierbürste gleichgerichtet zur Durchlaufrichtung der Platte.Preferably, the flap brush rotates at a speed of 1400 min -1 and, like the subsequent polishing brush same direction as the direction of passage of the plate.

Des Weiteren ist erfindungsgemäß vorgesehen vor dem Eingriff der Lamellenbürste ein Reinigungsmittel aufzutragen, was in an sich bekannter Weise mittels einer Sprühdüse erfolgt.Furthermore, according to the invention, a cleaning agent is applied before the lamella brush engages, which is done in a manner known per se by means of a spray nozzle.

Als Polierbürste, die mit der formstabilen Poliermasse beaufschlagt wird, hat sich als besonders vorteilhaft eine Tuchbürste herausgestellt, ebenfalls in Form einer Lamellenbürste, die bevorzugt mit einer Umdrehungszahl von 2000 min-1 angetrieben wird, während nachgeordnet eine weitere Bürste installiert ist, die als sogenannter Tuchläpper oder als Schwabbelscheibe ausgebildet ist und mit einer Umdrehungszahl von 1400 min-1 angetrieben wird, wobei alle rotierenden Werkzeuge gleichgerichtet mit dem Durchlauf der Platte bewegt werden.As a polishing brush, which is applied to the dimensionally stable polishing compound, has proven to be particularly advantageous a cloth brush been found also in the form of a flap brush, which preferably is driven min -1 at a revolution number of 2000, whereas downstream of a further brush is installed, a so-called Cloth lapper or as a buffing wheel and is driven at a speed of 1400 min -1 , all rotating tools being moved in the same direction as the plate passes.

Zwischen dem die Poliermasse tragenden Polierwerkzeug und dem Tuchläpper wird ebenfalls ein Reinigungsmittel aufgesprüht, wodurch sich eine optimale Oberflächenbeschaffenheit der bearbeiteten Kante ergibt.A cleaning agent is also sprayed on between the polishing tool carrying the polishing compound and the cloth lapper, which results in an optimal surface finish of the processed edge.

Weitere vorteilhafte Ausbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet.Further advantageous developments of the invention are characterized in the subclaims.

Ausführungsbeispiele der erfindungsgemäßen Vorrichtung werden nachfolgend anhand der beigefügten Zeichnungen beschrieben.Embodiments of the device according to the invention are described below with reference to the accompanying drawings.

In der Figur 1 ist eine Vorrichtung zur Kantenbearbeitung einer beschichteten oder zu beschichtenden Platte 11, vorzugsweise einer Möbelplatte, dargestellt, die ein Obertrum 1 und ein Untertrum 2 aufweist, zwischen denen die Platte 11 fortschreitend im Durchlauf bewegbar ist, entsprechend der Richtung, die durch einen rechts in der Darstellung erkennbaren Pfeil ausgewiesen ist.In the Figure 1 is a device for edge processing of a coated or to be coated plate 11, preferably a furniture plate, shown, which has an upper run 1 and a lower run 2, between which the plate 11 is progressively movable in the passage, according to the direction shown by a right in the Illustration recognizable arrow is shown.

Im Einlaufbereich seitlich angeordnet sind einen ober- und unterseitigen, frei liegenden Randbereich einer Längskante der Platte mit einem Trennmittel benetzende Sprühköpfe 3 vorgesehen.Arranged laterally in the inlet area are an upper and lower side, exposed edge area of a longitudinal edge of the plate with spray heads 3 wetting with a release agent.

Den Sprühköpfen 3 nachgeordnet sind Formatfräser 4, mit denen die entsprechende, zunächst noch unbeschichtete Kante der Platte bearbeitbar ist. Daran schließt sich eine Andruckrolle 5 an, mittels derer ein zuvor erwärmtes Kantenband an die Kante der Platte andrückbar ist, wobei eine Verbindung des Kantenbandes mit der Platte vorzugsweise durch Laser- oder Plasmastrahlen erfolgt, mit denen das zumindest einseitig klebfähige Kantenband bis zur Klebeaktivierung erwärmt wird.The spray heads 3 are followed by format cutters 4, with which the corresponding, initially still uncoated edge of the plate can be machined. This is followed by a pressure roller 5, by means of which a previously heated edge band can be pressed against the edge of the plate, the edge band being connected to the plate preferably by means of laser or plasma radiation, with which the edge band, which is adhesive at least on one side, is heated until the adhesive is activated .

Der Andruckrolle 5 ist ein Sprühgerät 6 zugeordnet, mit dem ein Gleitmittel auf die Randbereiche der Platte 11 und/oder auf die Andruckrolle 5 sprühbar ist.A pressure device 6 is assigned to the pressure roller 5, with which a lubricant can be sprayed onto the edge areas of the plate 11 and / or onto the pressure roller 5.

Kappsägen 9 dienen der folgenden weiteren Bearbeitung der Platte 11 ebenso, wie Kantenfräser 10, mit denen beidseitig der Platte 11 überstehende Randbereiche des Kantenbandes abgetragen werden.Cross-cut saws 9 serve the following further processing of the plate 11 as well as edge milling cutters 10, with which edge regions of the edge band projecting on both sides of the plate 11 are removed.

Um zu verhindern, dass durch die spangebende Bearbeitung anfallende Späne durch elektrostatische Aufladung an den Oberflächen der Platte 11 und des Kantenbandes anhaften, wird mittels den Kantenfräsern 10 vorgelagerten Sprühgeräten 8 ein antistatisch wirkendes Kühlmittel aufgebracht.In order to prevent chips resulting from the machining by electrostatic charging from adhering to the surfaces of the plate 11 and the edge band, an antistatic coolant is applied by means of the spraying devices 8 located in front of the edge milling cutters 10.

Nach dem Abtrag der Überstände des Kantenbandes erfolgt ein Polieren der spangebend bearbeiteten Kanten des Kantenbandes durch rotierende Polierscheiben 12, auf die eine formstabile Poliermasse 13, vorzugsweise ein Hartwachs aufgebracht ist.After the excess of the edge band has been removed, the machined edges of the edge band are polished by rotating polishing discs 12, to which a dimensionally stable polishing compound 13, preferably a hard wax, is applied.

Hierzu ist eine die Poliermasse 13 aufnehmende Haltevorrichtung 7 vorgesehen, mit der die Poliermasse 13 gegen die Polierscheibe 12 drückbar ist. Im Beispiel sind dem Obertrum 1 und dem Untertrum 2 jeweils eine Haltevorrichtung 7 zugeordnet.For this purpose, a holding device 7 is provided, which holds the polishing compound 13 and with which the polishing compound 13 can be pressed against the polishing disc 12. In the example, the upper run 1 and the lower run 2 are each assigned a holding device 7.

In der Figur 2 ist in vergrößerter Darstellung in einem Teilausschnitt der Vorrichtung der sozusagen Polierbereich erkennbar. Hier ist zu sehen, dass in Durchlaufrichtung vor den Polierscheiben 12 Lamellenbürsten 14 angeordnet sind, die nach einem Auftrag von mittels Sprühdüsen 16 aufgebrachtem Reinigungsmittel zum Einsatz kommen, wobei die Lamellen der Lamellenbürsten 14 wechselnd aus Tuch und Sisal bestehen.In the Figure 2 the polishing area can be seen in an enlarged representation in a partial section of the device. Here it can be seen that in the direction of travel, in front of the polishing disks 12, lamella brushes 14 are arranged, which are used after an application of cleaning agent applied by means of spray nozzles 16, the lamellae of the lamella brushes 14 alternatingly consisting of cloth and sisal.

Den Polierscheiben 12 nachgeordnet sind weitere Sprühdüsen 16 zum Auftrag von Reinigungsmittel, denen der Einsatz von rotierenden, sogenannten Tuchläppern 15 folgt, bei denen die Lamellen ausschließlich aus Tuch bestehen. Wie erkennbar, entspricht die Drehrichtung aller Polierwerkzeuge der Durchlaufrichtung der Platte 11.Downstream of the polishing discs 12 are further spray nozzles 16 for applying cleaning agents, which are followed by the use of rotating, so-called cloth lappers 15, in which the lamellae consist exclusively of cloth. As can be seen, the direction of rotation of all the polishing tools corresponds to the direction of travel of the plate 11.
