Description
Die Erfindung betrifft ein Verfahren und ein Bearbeitungsaggregat zum Bündigfräsen und/oder Abziehen eines auf die Schmalseiten plattenförmiger Werkstücke aus Holz und/oder Holzersatzstoffen aufgebrachten Kantenbandes.The invention relates to a method and a processing unit for flush trimming and / or removal of a plate on the narrow sides of workpieces made of wood and / or wood substitutes applied edge band.
Insbesondere beim Bau von Möbeln und dergleichen stellt sich häufig die Aufgabe, die Schmalseiten plattenförmiger Werkstücke aus Holz und/oder Holzersatzstoffen zu verblenden. In der Regel geschieht dies, indem auf den Schmalseiten sogenannte Kantenbänder angebracht werden. In der Regel ist dabei eine Nachbearbeitung erforderlich, beispielsweise, wenn die Kantenbänder aufgrund ihrer Breite über die Schmalseite hinaus überstehen. Der Übergang zwischen dem Kantenband und der Plattenoberfläche befindet sich dabei häufig im Sichtbereich, weswegen hohe Anforderungen an die optische Qualität des Übergangs gestellt werden. Dazu kommen häufig funktionale Anforderungen, wenn beispielsweise das Eindringen von Feuchtigkeit im Übergangsbereich zwischen Kantenband und einer unter Umständen vorhandenen wasserabweisenden Plattenbeschichtung verhindert werden soll.In particular, in the construction of furniture and the like, the task is often to blind the narrow sides of plate-shaped workpieces made of wood and / or wood substitutes. As a rule, this is done by attaching so-called edge bands on the narrow sides. As a rule, a post-processing is required, for example, if the edge bands survive beyond the narrow side due to their width. The transition between the edge band and the plate surface is often in the field of view, which is why high demands are placed on the optical quality of the transition. In addition, there are often functional requirements, for example, if the ingress of moisture in the transition region between the edge band and a water-repellent plate coating possibly present should be prevented.
Aus dem Stand der Technik, beispielsweise aus der
Das Schwenken des gesamten Aggregats zur Zustellung der Werkzeuge ist jedoch in der Praxis mit dem Nachteil verbunden, dass ein Schwenken des Angriffswinkels des Aggregats zu anderen Zwecken, beispielsweise wenn die räumliche Situation bei der Bearbeitung dies erfordert, nicht mehr möglich ist, ohne die Zustellung des Werkzeugs zu beeinflussen. Insbesondere bei der Fräsbearbeitung, bei der durch die Werkzeugrotation dessen Angriffswinkel um die Drehachse des Werkzeugs frei variiert werden kann, stellt dies eine Beeinträchtigung der Einsetzbarkeit des Bearbeitungsaggregats dar. Ein weiterer schwerwiegender Nachteil ist, dass nur feste, durch die Bauform des horizontalen Anschlags vorgegebene Zustellpositionen angefahren werden können. In der Praxis weist das Kantenband und/oder dessen Verleimung jedoch eine Dickentoleranz auf, auf die mit Bearbeitungsaggregaten gemäß des Standes der Technik nur dann in einem ausreichenden Maße reagiert werden kann, wenn der Bearbeitungsprozess unterbrochen und die Anschläge des Bearbeitungsaggregats entsprechend nachjustiert werden.The pivoting of the entire unit for the delivery of the tools, however, in practice has the disadvantage that a pivoting of the attack angle of the unit for other purposes, for example, when the spatial situation in the processing requires this is no longer possible without the delivery of Influence tool. In particular, in the milling, in which can be freely varied by the tool rotation whose attack angle about the axis of rotation of the tool, this is a deterioration of the applicability of the processing unit. Another serious drawback is that only fixed, predetermined by the design of the horizontal stop delivery positions can be approached. In practice, however, the edge band and / or its gluing has a thickness tolerance, which can only be reacted to a sufficient extent with processing units according to the prior art if the machining process is interrupted and the stops of the processing unit are readjusted accordingly.
Der Erfindung liegt die Aufgabe zugrunde, ein Bearbeitungsaggregat zu schaffen und ein Verfahren zur Bearbeitung anzugeben, welches die angesprochenen Nachteile des Standes der Technik nicht oder in verringertem Umfang aufweist.The invention has for its object to provide a processing unit and to provide a method for processing, which does not have the disadvantages of the prior art or in a reduced extent.
Gelöst wird die Aufgabe durch ein Verfahren mit den Merkmalen des Anspruchs 1 und ein Bearbeitungsaggregat mit den Merkmalen des Anspruchs 6. Vorteilhafte Ausführungen finden sich in den jeweiligen Unteransprüchen.The object is achieved by a method having the features of claim 1 and a processing unit having the features of
Erfindungsgemäß wird die Aufgabe dadurch gelöst, dass ein Antrieb vorgesehen ist, der die Zustellung des Fräs- und/oder Abziehwerkzeugs (im Folgenden Werkzeug) erlaubt, ohne dass hierfür manuelle Eingriffe am Bearbeitungsaggregat notwendig sind, wodurch eine Korrektur oder Anpassung der Zustellung des Werkzeugs sowohl während der Bearbeitung erfolgen kann als auch zwischen einzelnen Bearbeitungsschritten möglich ist, beispielsweise zwischen einem Fräs- und einem Abziehzyklus, was es ermöglicht, beide Bearbeitungsschritte mit dem gleichen Bearbeitungsaggregat vorzunehmen, ohne eine längere Pause zwischen den Bearbeitungsschritten in Kauf nehmen zu müssen.According to the invention the object is achieved in that a drive is provided which allows the delivery of the milling and / or Abziehwerkzeugs (hereinafter tool), without requiring manual intervention on the processing unit, whereby a correction or adjustment of the delivery of the tool both during processing can be done as well as between individual processing steps is possible, for example, between a milling and a Abziehzyklus, which makes it possible to carry out both processing steps with the same processing unit, without having to take a longer break between the processing steps in purchasing.
Vorteilhaft ist dabei, dass auf Schwankungen der Dicke des Kantenbandes unmittelbar reagiert werden kann, wenn Daten über die tatsächliche Dicke des Kantenbandes zur Verfügung stehen. Vorteilhafterweise werden die Daten über die tatsächliche Dicke des Kantenbandes erfasst, was unter Berücksichtigung des jeweiligen Bekantungsverfahrens vor, während oder nach dem Aufbringen des Kantenbandes auf die Schmalseite erfolgen kann und nach der Erfassung der Daten zur Steuerung der Zustellung des Werkzeugs verwendet. Vorzugsweise ist hierfür eine geeignete Steuerung vorgesehen, die die Daten verarbeiten kann und die vorzugsweise eine geeignete Datenübermittlungseinrichtung aufweist, um im Bereich vorgeschalteter Produktionsschritte erfasste Daten über die tatsächliche Dicke des Kantenbandes an die Steuerung des Bearbeitungsaggregats zu übermitteln.It is advantageous in this case that it is possible to react directly to fluctuations in the thickness of the edge band when data about the actual thickness of the edge band are available. Advantageously, the data on the actual thickness of the edge band are detected, which can be done taking into account the respective Bekantungsverfahrens before, during or after the application of the edge band on the narrow side and after the collection of data used to control the delivery of the tool. Preferably, for this purpose, a suitable control is provided which can process the data and which preferably has a suitable data transmission device in order to transmit in the area of upstream production steps recorded data on the actual thickness of the edge band to the control of the processing unit.
Vorzugsweise ist das Bearbeitungsaggregat mit Werkzeugen zum Bündigfräsen und Abziehen ausgestattet, so dass mit dem Bearbeitungsaggregat zunächst das Bündigfräsen und danach das Abziehen als abschließende Feinbearbeitung unmittelbar aufeinanderfolgender Prozessschritte vorgenommen werden kann. Besonders bevorzugt wird hierbei eine der Formschneiden eines Fräswerkzeugs als Abziehwerkzeug verwendet, wofür diese Formschneide durch Drehen des Werkzeugs und/oder des Bearbeitungsaggregates auf das Kantenband ausgerichtet wird und das bei der Fräsbearbeitung in der Regel rotierende Werkzeug in seiner Rotationsbewegung arretiert wird. Vorzugsweise ist hierfür eine Arretiervorrichtung vorgesehen, die derart ausgebildet und angesteuert ist, dass eine Arretierung des Werkzeugs in einer Position möglich ist, in der eine der Formschneiden des Werkzeugs sich in einer zum Kantenband hin vorstehenden Position befindet und so am Kantenband zum Abziehen in Eingriff gebracht werden kann, ohne dass andere am Werkzeug vorgesehene Schneiden die Abziehbearbeitung behindern.Preferably, the processing unit is equipped with tools for flush trimming and peeling, so that with the processing unit first flush trimming and then stripping can be made as a final fine machining of immediately successive process steps. In this case, one of the form cutting edges of a milling tool is particularly preferably used as a removal tool, for which purpose this shape cutting edge is aligned by turning the tool and / or the processing unit onto the edge band and the tool, which generally rotates during the milling process, is locked in its rotational movement. Preferably, a locking device is provided for this purpose, which is designed and controlled such that a locking of the tool in a position is possible in which one of the mold edges of the tool is in a position towards the edge band protruding position and so brought to the edge band for pulling engaged can be without hindering provided on the tool cutting the Abziehbearbeitung.
Die Zustellung erfolgt dadurch, dass eine relative Verschiebung von Anschlag und Werkzeug vorgenommen wird. Alternativ können statt der Anschläge auch Tastelemente vorgesehen sein, bei denen es sich um berührungssensitive Sensoren oder auch distanzsensitive Sensoren, beispielsweise auf optischer Basis (z.B. Laser) handeln kann und die in Verbindung mit der Ansteuerung der Positioniereinrichtung(en) des Bearbeitungsaggregats die Wirkung mechanischer Anschläge berührungslos, beziehungsweise mit nur minimalen Berührungen ermöglichen, was im Fall empfindlicher Beschichtungen von Vorteil ist. Der besseren Verständlichkeit halber wird im Folgenden nur von Anschlägen gesprochen, wobei Anschläge für Anschläge und/oder Tastelemente im vorstehenden Sinne steht.The delivery takes place in that a relative displacement of stop and tool is made. Alternatively, instead of the attacks and tactile elements be provided, which may be touch-sensitive sensors or distance-sensitive sensors, for example on an optical basis (eg laser) and in conjunction with the control of the positioning (s) of the processing unit, the effect of mechanical attacks contact, or with minimal contact which is advantageous in the case of sensitive coatings. For the sake of clarity, only stops will be discussed below, with stops for stops and / or feeler elements being in the above sense.
Vorzugsweise liegen die Verschieberichtungen dann orthogonal und/oder parallel zur Breitenrichtung des Kantenbandes, wodurch sich die Ansteuerung vereinfacht. Da die erfindungsgemäßen Bearbeitungsaggregate in der Regel nur einen begrenzten Bauraum und ein begrenztes Gewicht aufweisen dürfen, auf der anderen Seite jedoch hohe Anforderungen an die Positioniergenauigkeit des erfindungsgemäßen Zustellantriebs gestellt werden, sind zu dessen technischer Realisierung vorteilhafterweise in Schneckenräder eingreifende Schnecken vorgesehen, da diese eine hohe Positioniergenauigkeit bei kleiner Baugröße ermöglichen und darüber hinaus aufgrund der Eingriffswinkel der Schnecke in das Schneckenrad eine Selbsthemmung ermöglichen, was eine zusätzliche Arretiervorrichtung des Zustellantriebs verzichtbar machen kann. Der Antrieb kann dabei derart ausgeführt sein, dass er auf einen Anschlag wirkt, der vorzugsweise aus dessen Normalenrichtung am Kantenband angreift. Dabei kann der Antrieb über eine Exzenterwelle erfolgen, deren Drehung eine lineare Verschiebung des Anschlags ermöglicht. Vorzugsweise wird die Exzenterwelle, insbesondere im Hinblick auf den benötigten Bauraum, dabei so platziert, dass sie zumindest im Wesentlichen parallel zur Spindelachse verläuft. Dabei kann beispielsweise das Schneckenrad an der Exzenterwelle vorgesehen sein, so dass eine Schnecke am Schneckenrad angreifen und so die Exzenterwelle drehen kann, wodurch der an der Exzenterwelle mit einem Achsenversatz aufgenommene Anschlag linear bewegt wird.Preferably, the displacement directions are then orthogonal and / or parallel to the width direction of the edge band, which simplifies the control. Since the processing units according to the invention usually have only a limited space and a limited weight, on the other hand, however, high demands are placed on the positioning accuracy of the feed drive according to the invention, for its technical realization advantageously in worm gears engaging snails are provided, as these high Allow positioning accuracy with small size and also allow due to the pressure angle of the worm in the worm wheel self-locking, which can make an additional locking device of the Zustellantriebs unnecessary. The drive can be designed such that it acts on a stop, which preferably acts on the edge band from its normal direction. In this case, the drive can take place via an eccentric shaft whose rotation allows a linear displacement of the stop. Preferably, the eccentric shaft, in particular with regard to the required space, thereby placed so that it extends at least substantially parallel to the spindle axis. In this case, for example, the worm wheel may be provided on the eccentric shaft, so that a worm can engage the worm wheel and thus rotate the eccentric shaft, whereby the stop received on the eccentric shaft with an axial offset is moved linearly.
Alternativ kann der Zustellantrieb auch auf das Werkzeug wirken. Bevorzugt kann dabei das Werkzeug parallel zur Richtung der Arbeitsspindel verstellt werden, wenn das Werkzeug an der Arbeitsspindel verschiebbar aufgenommen ist. Hierfür kann das Werkzeug in einer Hülse gelagert werden, die in einer geeigneten gestellfesten Halterung, beispielweise einem Haltering, angeordnet ist. Wenn die Hülse mit dem Haltering über ein Gewinde verbunden ist, so ist es möglich, mit einem Antrieb eine Drehbewegung der Hülse zu bewirken, die aufgrund des Gewindes dadurch linear parallel zur Spindelachse verschoben wird und so die Zustellung des Werkzeugs bewirkt. Hierzu ist vorteilhafterweise ein Schneckenrad an der Hülse vorgesehen, in das die durch den Zustellantrieb angetriebene Schnecke eingreift.Alternatively, the feed drive can also act on the tool. Preferably, the tool can be adjusted parallel to the direction of the work spindle when the tool is slidably received on the work spindle. For this purpose, the tool can be stored in a sleeve which is arranged in a suitable frame-fixed holder, for example a retaining ring. When the sleeve is connected to the retaining ring via a thread, it is possible to effect a rotary movement of the sleeve with a drive, which is thereby displaced linearly parallel to the spindle axis due to the thread and thus causes the delivery of the tool. For this purpose, a worm wheel is advantageously provided on the sleeve, in which engages the driven by the feed screw screw.

Erfindungsgemäß weist das Bearbeitungsaggregat eine Arbeitsspindel 1 auf, an der das Werkzeug 2 mit seinen Formschneiden 3 aufgenommen ist. Das plattenförmige Werkstück 4, das eine Oberflächenbeschichtung 4a aufweisen kann, weist ein Kantenband 5 auf, welches vor der Bearbeitung mit dem erfindungsgemäßen Bearbeitungsaggregat auf die Schmalseite des Werkstückes 4 aufgebracht wird. Bei der Bearbeitung geben vertikal am plattenförmigen Werkstück 4 angreifende Anschläge 6 oder am Kantenband angreifende Anschläge 7 die relative Position des Werkzeugs 2 zum Werkstück 4 vor. Bei zu geringer Zustellung kommt es zu überstehendem Kantenbandmaterial und damit zur Bildung der Grate 5a. Bei zu starker Zustellung kommt es zu starkem Materialabtrag und damit zur Beschädigung der Oberflächenbeschichtung 4a im Übergangsbereich 5b zum Kantenband 5.According to the invention, the processing unit has a work spindle 1, on which the
Das erfindungsgemäße Bearbeitungsaggregat weist gemäß eines Ausführungsbeispiels zwei vertikale Anschläge 6 auf, die an den Flächenseiten des plattenförmigen Werkstücks angreifen sowie einen Anschlag 7, der an dem Kantenband angreift. Diese Anschläge stellen die korrekte Relativposition des Werkzeugs 2 zum Werkstück sicher. Bei dem beispielhaften Bearbeitungsaggregat sind zwei Werkzeuge 2 vorgesehen, es sind jedoch auch Ausführungsformen mit nur einem Werkzeug oder mit einer Mehrzahl Werkzeuge denkbar. Der am Kantenband 5 angreifende Anschlag 7 ist derart ausgeführt, dass er bei dem beispielhaften Aggregat aufgrund seiner bogenförmigen Kontur den Angriff am Kantenband 5 aus verschiedenen Winkeln verschwenkt um die Spindelachse ermöglicht.The processing unit according to the invention has, according to one embodiment, two
In der ersten beispielhaften Ausführungsform ist der Anschlag 7 durch einen Antrieb verstellbar ausgeführt. Erfindungsgemäß ist der Motor 26 vorgesehen, der auf die Schnecke 32 wirkt, die wiederum am Schneckenrad 33 angreift, das an der Exzenterwelle 34 vorgesehen ist. Am Achsmittenversatz 35 der Exzenterwelle 34 ist mittels des Langlochs 36 der Anschlag 7 derart angelenkt, dass er durch den erfindungsgemäßen Antrieb mit der Exzenterwelle in seiner Führung, bestehend aus den Führungsbolzen 38 am Anschlag 7 und den Führungsstücken 37 am Gestell, linear verschoben werden kann, wodurch die erfindungsgemäße angetriebene Zustellung des Werkzeugs realisiert ist.In the first exemplary embodiment, the
Im anderen Ausführungsbeispiel wird das Werkzeug entlang der Spindelachse verschoben und damit relativ zu den Anschlägen, wodurch ebenfalls die erfindungsgemäß angetriebene Zustellung realisiert wird. Im konkreten Beispiel geschieht das durch die vom Motor 25 angetriebene Schnecke 29, die in das Schneckenrad 30 angreift, das an der Hülse 13 vorgesehen ist. In der Hülse 13 ist der Wellenstummel 12 drehbar gelagert. Der Wellenstummel 12 trägt zum Einen das Werkzeug 2, zum Anderen ist er axial verschieblich mit dem Spindelantrieb verbunden. Die Hülse 13 verfügt über ein Außengewinde 14, das in das Innengewinde 28 eines gestellfesten Halteelements 18 eingreift. Durch die Schnecke wird die Hülse 13 in dem Gewinde gedreht, wodurch eine axiale Verschiebung des Werkzeugs 2 auf der Spindel und damit die erfindungsgemäße Zustellung stattfindet. Diese Ausgestaltungsvariante erlaubt eine hochpräzise Zustellung durch das sich aus dem Eingriff der Schnecke 29 an dem Schneckenrad 30 und der daraus resultierenden Verstellung über das Gewinde 14, 28 ergebende hohe Übersetzungsverhältnis des Zustellungantriebs.In the other embodiment, the tool is displaced along the spindle axis and thus relative to the stops, whereby also the invention driven delivery is realized. In the specific example, this is done by the
