Description

Verfahren und Vorrichtung zur Kantenbearbeitung einer Platte, vorzugsweise einer Möbelplatte  Method and device for edge processing of a plate, preferably a furniture plate
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 coated with an edge band plate, preferably a furniture plate according to the preamble of claim 1 and an apparatus for performing the method.
Insbesondere Möbelplatten aus Holz oder einem Holzwerkstoff werden kanten- seitig 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 äu ßeren Einflüssen zu schaffen. 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- o- der Plasmastrahlen erfolgt. 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 der- gleichen zum Einsatz. In particular furniture panels made of wood or a wood material edge side coated with a so-called edge band to complete the usual way top and bottom already provided with a decorative layer plate and so on the one hand pleasing to the viewer overall impression and on the other hand protection of the core of the plate to avoid external influences. In this case, edge bands made of polishable plastic, such as acrylic or the like, are increasingly being used, which can be adhesively bonded at least on one side by thermal treatment, the heating taking place for example by means of laser or plasma jets. To take account of thickness tolerances of the plate, d. h., To ensure complete coverage of the plate edge, the edge band is designed so that some supernatant remains on the top and / or bottom side after sticking, which is removed in a subsequent step. For this purpose, suitable cutting tools, such as milling cutters, scrapers or the like are used.
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. 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. Jedoch hat sich die Konsistenz dieses Poliermittels 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 edgeband undergoes a so-to-speak surface damage due to a roughness that is greater than that of the unprocessed surface, with the result that this surface appears dull against the unworked, high-gloss surface in the sense of matt. In particular, for design reasons, this represents a recognizable defect that sets the visual value of the entire furniture panel down. To remedy this situation, the use of a polishing tool is proposed in DE 20 2005 002 637 U1, to which a viscous or pasty polishing agent is applied. However, the consistency of this polish has been found to be detrimental, particularly with respect to the operation of the overall apparatus, as the polishing agent applied to the rotary polishing tool is thrown uncontrollably into space, resulting in significant contamination of the processing machine as a whole, or at least in the surrounding area of the polishing tool results. Naturally, this circumstance precludes optimal operation since, in particular, the aggregates involved in the production process are adversely affected by contamination and because of this, too frequent interruptions of operation occur.
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 Betriebsab- laufs, insbesondere hinsichtlich einer Bearbeitung des Kantenbands möglich ist. The object of the invention is to further develop a method and a device of the generic type such that an optimization of the operating sequence, in particular with regard to machining of the edge band, is possible with a low constructional and manufacturing outlay.
Diese Aufgabe wird durch ein Verfahren mit den Merkmalen des Anspruchs 1 bzw. eine Vorrichtung mit den Merkmalen des Anspruchs 7 gelöst. This object is achieved by a method having the features of claim 1 and a device having the features of claim 7.
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, the automatic loading of the polishing tool, for example a polishing belt, a rotating polishing brush or disk, with e.g. Hard wax provides, contamination 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 overall service life of the device increases. As a consequence, this leads to a quite remarkable minimization of the operating costs.
Nach einer vorteilhaften Weiterbildung wird die Poliermasse intermittierend auf das Polierwerkzeug aufgetragen. Dazu weist die Haltevorrichtung eine entsprechende Nachstelleinrichtung auf, mit der im Übrigen die beispielsweise in Blockform vorliegende Poliermasse mit einem derartigen Druck am Polierwerk- zeug anliegt, dass ein Abtrag auf das Polierwerkzeug gewährleistet ist. According to an advantageous development, the polishing compound is applied intermittently to the polishing tool. For this purpose, the holding device has a corresponding adjusting device with which, moreover, the polishing compound, for example in block form, bears on the polishing tool with such a pressure that a removal onto 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 ent- spricht die nun glänzende Oberfläche der bearbeiteten Kante der der unbearbeiteten Oberfläche, die quasi die Breitseite des Kantenbandes sichtseitig bildet. 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. As has been surprisingly found, a high-gloss surface is achieved by the polishing, especially by means of hard wax, which, as described, previously appeared dull by the machining. In that regard, speaks the now shiny surface of the processed edge of the unprocessed surface, which forms virtually the broad side of the edge band visible. 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 bearbei- tet 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) of a thermoplastic plastic, for example polyethylene terephthalate (PET) or of 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, of course, other dimensionally stable polishing compositions are conceivable if they lead to the same result, namely to create a high-gloss surface of the machined areas.
Ein weiterer Gedanke der Erfindung sieht vor, dass in Durchlaufrichtung der Platte vor dem Angriff des Polierwerkzeuges, der jeweils spanend bearbeiteten Kante zugeordnet, eine Bürste angreift, vorzugsweise eine Lamellenbürste, bestehend aus abwechselnd Tuch- und Sisal-Lamellen, 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. Another idea of the invention provides that in the direction of passage of the plate before the attack of the polishing tool, each associated machined edge, a brush attacks, preferably a lamella brush, consisting of alternating cloth and sisal slats, the sisal slats in particular for machining a radius produced by the machining, 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. Des Weiteren ist erfindungsgemäß vorgesehen vor dem Eingriff der Lamellenbürste ein Reinigungsmittel aufzutragen, was in an sich bekannter Weise mittels einer Sprühdüse erfolgt. Preferably, the flap brush rotates at a number of revolutions of 1400 min "1 and, like the subsequent polishing brush same direction as the direction of passage of the plate. Furthermore, the invention provides in front of the engagement of the flap brush to apply a cleaning agent, which is done in known manner 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 acted upon by the dimensionally stable polishing composition, a cloth brush has been found to be particularly advantageous, also in the form of a lamella brush, which is preferably driven with a number of revolutions of 2000 min "1 , while downstream of a further brush is installed, the so-called Tuchläpper or is designed as a buffing wheel and with a rotation speed of 1400 min "1 is driven, all rotating tools are moved rectified with the passage of the plate.
Zwischen dem die Poliermasse tragenden Polierwerkzeug und dem Tuchlapper 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 flapper, resulting in an optimum surface finish of the machined edge.
Weitere vorteilhafte Ausbildungen der Erfindung sind in den Unteransprüchen gekennzeichnet. Further advantageous embodiments of the invention are characterized in the subclaims.

In der Figur 1 ist eine Vorrichtung zur Kantenbearbeitung einer beschichteten oder zu beschichtenden Platte 1 1 , vorzugsweise einer Möbelplatte, dargestellt, die ein Obertrum 1 und ein Untertrum 2 aufweist, zwischen denen die Platte 1 1 fortschreitend im Durchlauf bewegbar ist, entsprechend der Richtung, die durch einen rechts in der Darstellung erkennbaren Pfeil ausgewiesen ist. 1 shows a device for edge processing of a coated or to be coated plate 1 1, preferably a furniture plate, shown having an upper run 1 and a lower run 2, between which the plate 1 1 is progressively movable in the passage, according to the direction, which is indicated by an arrow visible on the right in the illustration.
Im Einlaufbereich seitlich angeordnet sind einen ober- und unterseitigen, frei liegenden Randbereich einer Längskante der Platte mit einem Trennmittel be- netzende Sprühköpfe 3 vorgesehen. Arranged laterally in the inlet region, there are provided an upper and lower side, exposed edge region of a longitudinal edge of the plate with spray heads 3 which connect 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 Kanten- band 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. Der Andruckrolle 5 ist ein Sprühgerät 6 zugeordnet, mit dem ein Gleitmittel auf die Randbereiche der Platte 1 1 und/oder auf die Andruckrolle 5 sprühbar ist. Downstream of the spray heads 3 are milling cutters 4, with which the corresponding, initially 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 is pressed against the edge of the plate, wherein a connection of the edge band to the plate is preferably carried out by laser or plasma jets, with which the at least one side adhesive edge band until the adhesive activation is heated. The pressure roller 5 is associated with a spray device 6, with which a lubricant on the edge regions of the plate 1 1 and / or on the pressure roller 5 can be sprayed.
Kappsägen 9 dienen der folgenden weiteren Bearbeitung der Platte 1 1 ebenso, wie Kantenfräser 10, mit denen beidseitig der Platte 1 1 überstehende Randbereiche des Kantenbandes abgetragen werden. Chop saws 9 are used for the following further processing of the plate 1 1 as well as edgers 10, with which both sides of the plate 1 1 protruding edge regions of the edge band are removed.
Um zu verhindern, dass durch die spangebende Bearbeitung anfallende Späne durch elektrostatische Aufladung an den Oberflächen der Platte 1 1 und des Kantenbandes anhaften, wird mittels den Kantenfräsern 10 vorgelagerten Sprühgeräten 8 ein antistatisch wirkendes Kühlmittel aufgebracht. In order to prevent accumulating by the cutting machining chips by electrostatic charge to adhere to the surfaces of the plate 1 1 and the edge band, an antistatic coolant is applied by means of the edgers 10 upstream sprayers 8.
Nach dem Abtrag der Überstände des Kantenbandes erfolgt ein Polieren der spangebend bearbeiteten Kanten des Kantenbandes durch rotierende Polier- Scheiben 1 2, auf die eine formstabile Poliermasse 1 3, vorzugsweise ein Hartwachs aufgebracht ist. After the removal of the supernatants of the edge band polishing of the machined edges of the edgeband edged by rotating polishing discs 1 2, to which a dimensionally stable polishing mass 1 3, 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 polishing compound 13 receiving holding device 7 is provided, with which the polishing mass 13 can be pressed against the polishing pad 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. 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 1 1 . Bezuqszeichenliste FIG. 2 shows in an enlarged view in a partial section of the device the so-called polishing area. Here it can be seen that in the direction of passage in front of the polishing wheels 12 lamella brushes 14 are arranged, which are used after an application of applied by means of spray nozzles 16 cleaning agent, wherein the lamellae of the lamellar brushes 14 alternately made of cloth and sisal. Downstream of the polishing pads 12 are further spray nozzles 16 for the application of cleaning agents, which are followed by the use of rotating, so-called Tuchläppern 15 in which the slats consist exclusively of cloth. As can be seen, the direction of rotation of all polishing tools corresponds to the direction of passage of the plate 11. LIST OF REFERENCES
