Description

Technisches GebietTechnical area

Die vorliegende Erfindung betrifft eine Bearbeitungsvorrichtung gemäß dem Oberbegriff des Anspruchs 1. Eine solche Vorrichtung ist aus der US 2009/0007988 A1 bekannt. Derartige Maschinen werden beispielsweise im Bereich der Möbel- und Bauelementeindustrie eingesetzt, um Möbelfronten, Paneele, Türen, Fenster oder ähnliches zu bearbeiten.The present invention relates to a processing apparatus according to the preamble of claim 1. Such a device is known from US 2009/0007988 A1 known. Such machines are used for example in the field of furniture and component industry to edit furniture fronts, panels, doors, windows or the like.

Stand der TechnikState of the art

Im Bereich der Paneelherstellung aus Massivholzwerkstücken werden bisher sogenannte Kehlautomaten bzw. Hobelmaschinen verwendet, die Werkstücke vierseitig bearbeiten können. Solche Kehlautomaten sind jedoch hinsichtlich ihrer Funktionalität eingeschränkt, und weisen die folgenden Nachteile auf:
Zum Einen sind Kehlautomaten bzw. Hobelmaschinen nur bedingt in der Lage, sogenannte "Click" oder "Lock"-Profile an den Werkstückschmalseiten herzustellen, wie dies z.B. im Fußbodenbereich (Laminat, Parkett) oder bei Wand- und Deckenpaneelen üblich ist, da die Bearbeitungsmotoren solcher Maschinen nicht ausreichend verschwenkbar sind oder nicht mit einem ausreichend großen Verstellbereich ausgestattet sind. Zur Bearbeitung von Werkstückschmalseiten werden deshalb sogenannte Doppelendprofiler eingesetzt.In the field of panel production of solid wood workpieces previously so-called moulders or planers are used, which can work on four sides. However, such moulders are limited in their functionality, and have the following disadvantages:
On the one hand, moulders and planing machines are only partially able to produce so-called "click" or "lock" profiles on the narrow sides of the workpieces, as is customary in the floor area (laminate, parquet) or in wall and ceiling panels, for example, since the machining motors Such machines are not sufficiently pivotable or are not equipped with a sufficiently large adjustment. Therefore, so-called double-end tenoners are used for machining workpiece narrow sides.

Ferner werden bei Kehlautomaten bzw. Hobelmaschinen die Werkstücke während des Durchlaufs an einer festen Leiste entlang geführt, und gegen diese gehalten, sodass die Werkstücke im Bereich der Bearbeitungsstation maßhaltig bearbeitet werden können. Läuft ein Werkstück jedoch gekrümmt bzw. "bananenförmig" in eine solche Maschine ein, kehrt es nach der Bearbeitung in diese Form zurück. Ferner besteht die Gefahr, dass das Werkstück an der genannten Leiste verkratzt.Furthermore, in the case of moulders or planing machines, the workpieces are guided along a fixed strip during the passage, and held against them, so that the workpieces in the area of the processing station can be machined. However, if a workpiece runs curved or "banana-shaped" into such a machine, it will return to its original shape after machining. Furthermore, there is a risk that the workpiece will scratch the said strip.

Bei den sogenannten Doppelendprofilern sind die oben genannten Nachteile nicht vorhanden, da das Werkstück mit einer Förderbahn an schwenkbaren Bearbeitungsmotoren mit großen Verstellwegen entlangführt. Auf diese Weise können sogenannte "Click" und "Lock"-Profile hergestellt werden. Ferner ist ein spannungsfreier Einlauf möglich (die sogenannte "Bananenform" eines Werkstücks wird bei der Bearbeitung nicht durchgedrückt), und die Werkstücke verkratzen nicht, da sie auf der sich bewegenden Förderbahn aufliegen, anstatt entlang einer festen Anlage verschoben zu werden.In the so-called Doppelendprofilern the above-mentioned disadvantages are not present, since the workpiece with a conveyor track along pivotable machining motors along with large adjustment paths. In this way, so-called "Click" and "Lock" profiles can be produced. Furthermore, a stress-free enema is possible (the so-called "banana shape" of a workpiece is not pressed during machining), and the workpieces do not scratch because they rest on the moving conveyor rather than being displaced along a fixed abutment.

Der Aufbau der genannten Doppelendprofiler hat jedoch den Nachteil, dass keine Bearbeitung an der Ober- und Unterseite (Hauptseiten) des Werkstücks möglich ist, da ein Werkstück an seiner Unterseite mit der sich bewegenden Förderbahn und an der Oberseite mit einem Oberdruckriemen in Kontakt steht und durch diese gehalten wird.However, the structure of said double end tenoners has the disadvantage that no machining on the top and bottom (main sides) of the workpiece is possible, since a workpiece on its underside with the moving conveyor track and at the top with a top pressure belt in contact and through this is held.

Das Dokument DE 20 2006 020 304 U1 offenbart einen Doppelendprofiler mit einer oder zwei aus Kettengliedern ausgebildeten Führungsketten als umlaufende Werkstückauflage. Die in der DE 20 2006 020 304 U1 offenbarten Kettenglieder werden bei Durchlaufmaschinen wegen der bei diesen im Vordergrund stehenden Serienfertigung, den hohen Durchlaufgeschwindigkeiten der Werkstücke durch die Maschine und dem zuvor als groß angesehenen Einfluss der unteren, umlaufenden Werkstückauflage auf die Qualität der Bearbeitung eingesetzt. Die Werkstückauflage umlaufende Transportkette läuft auch hier in einer Ebene um, die rechtwinklig zur Transportebene des Werkstücks ist.
Es ist die US 4,457,350 A1 bekannt, die eine Hobelmaschine mit Bearbeitungswerkzeugen zur vielfältigen Bearbeitung zeigt.
Die DE 10 2006 019 298 A1 betrifft eine Verbesserung einer Doppelendprofiler-Maschine zum Bearbeiten von plattenförmigen Werkstücken für die Holz- und Baustoffindustrie.
Die DE 103 28204 A1 zeigt eine Maschine zum Profilieren von länglichen, plattenförmigen Werkstücken entlang der Längstkanten, wobei die Werkstücke durch eine Einlaufzone und eine Profilierungszone hindurchgeführt werden. In der Einlaufzone befindet sich ein Anschlaglineal, an dem die Werkstücke mit einer ihrer Längskanten auf die Durchlaufrichtung ausgerichtet werden.
Als weiteres Dokument ist die BE 650 647 A zu nennen, die eine Hobelmaschine zeigt, mit der ein Werkstück an vier Seiten bearbeitet werden kann.The document DE 20 2006 020 304 U1 discloses a Doppelendprofiler with one or two of chain links formed guide chains as a rotating workpiece support. The in the DE 20 2006 020 304 U1 disclosed chain links are in continuous machines because of the priority in this series production, the high throughput speeds of the workpieces through the machine and previously considered large impact of the lower, rotating workpiece support on the quality of machining used. The workpiece conveyor circulating conveyor chain also runs in a plane which is perpendicular to the transport plane of the workpiece.
It is the US 4,457,350 A1 known, which shows a planing machine with processing tools for versatile processing.
The DE 10 2006 019 298 A1 relates to an improvement of a double end tenoning machine for working plate-shaped workpieces for the wood and building materials industry.
The DE 103 28204 A1 shows a machine for profiling elongated plate-shaped workpieces along the longitudinal edges, wherein the workpieces are passed through an inlet zone and a profiling zone. In the inlet zone there is a stop ruler, on which the workpieces are aligned with one of their longitudinal edges in the direction of passage.
Another document is the BE 650 647 A to name a planing machine with which a workpiece can be processed on four sides.

Gemäß der Erfindung sind der weitere Oberdruck sowie die weitere Förderbahn des Einlaufbereichs unabhängig voneinander in der Höhe verstellbar. Durch die Höhenverstellung der weiteren Förderbahn des Einlaufbereichs kann der durch das Bearbeitungsaggregat des Einlaufbereichs vorgesehen Abtrag eingestellt werden.According to the invention, the further upper pressure and the further conveying path of the inlet region are independently adjustable in height. By adjusting the height of the further conveying path of the inlet region, the removal provided by the processing unit of the inlet region can be set.

In einer weiteren Ausführungsform ist der weitere Oberdruck des Einlaufbereichs jeweils mit einer Vielzahl von Rollenelementen versehen. Alternativ kann der weitere Oberdruck ein oder mehrere Riemen- oder Kettenelemente aufweisen. Falls mehrere Riemen- oder Kettenelemente vorgesehen sind, verlaufen diese parallel zur Durchlaufrichtung.In a further embodiment, the further upper pressure of the inlet region is in each case provided with a multiplicity of roller elements. Alternatively, the additional upper pressure may have one or more belt or chain elements. If several belt or chain elements are provided, these run parallel to the direction of passage.

Ferner ist es insbesondere vorgesehen, dass das zumindest eine erste Bearbeitungsaggregat und das zumindest eine zweite Bearbeitungsaggregat Hobelwerkzeuge und/oder Nutwerkzeuge sind. Mit diesen können jeweils die obere bzw. untere Hauptseite eines Werkstücks bearbeitet werden. Die Hobelwerkzeuge werden für einen flächigen Materialabtrag genutzt, während mit einem Nutwerkzeug bspw. eine Entspannungsnut in eine Hauptseite eines Werkstücks eingebracht wird. Ferner umfassen die genannten Werkzeuge ebenfalls Fräswerkzeuge sowie Sägen.Furthermore, it is provided in particular that the at least one first processing unit and the at least one second processing unit are planing tools and / or grooving tools. With these, the upper or lower main side of a workpiece can be processed.

The rollers of the first and second upper rolls pressure may be partially driven. However, they may also be non-driven rollers. In the area formed thereby between the first upper roll pressure 11 and the second upper roll pressure 12 processing units 13 are provided which can machine a workpiece from the top. However, it can be seen that in the context of the present invention, only one upper processing unit 13 can be provided. In the in FIG. 1 As shown, the first upper processing unit 13 in the direction of passage is provided with a planing tool, and the second upper processing unit 13 arranged downstream in the passage direction is provided with a groove tool for introducing relaxation grooves into a workpiece.

Darüber hinaus ist die zweite Förderbahn 10 derart von der ersten Förderbahn 2 beabstandet, dass in dem zwischen der ersten Förderbahn 2 und der zweiten Förderbahn 10 ausgebildeten Bereich ein unteres Bearbeitungsaggregat 14 vorgesehen sein kann, um Werkstücke von einer Unterseite zu bearbeiten.In addition, the second conveyor track 10 is spaced from the first conveyor track 2 in such a way that a lower processing unit 14 can be provided in the area formed between the first conveyor track 2 and the second conveyor track 10 in order to machine workpieces from a lower side.

Zwischen dem unteren Bearbeitungsaggregate 14 zur Bearbeitung einer zweiten Hauptseite des Werkstücks und der Förderbahn 2 ist eine Stützrolle 16, und zwischen dem unteren Bearbeitungsaggregat 14 und der weiteren Förderbahn 10 ist eine weitere Stützrolle 15 vorgesehen. Mit diesen kann eine durchgängige Abstützung eines Werkstücks erreicht werden. Die Stützrollen 15, 16 können angetrieben sein. Auch können neben den in Figur 1 gezeigten Stützrollen 15, 16 mehrere Stützrollen auf einer Seite des unteren Bearbeitungsaggregats vorgesehen sein. Statt der Stützrollen können auch starre Elemente bereitgestellt werden, über die ein Werkstück in Durchlaufrichtung gleitet.Between the lower processing units 14 for processing a second main side of the workpiece and the conveyor track 2 is a support roller 16, and between the lower processing unit 14 and the further conveyor track 10, a further support roller 15 is provided. With these, a continuous support of a workpiece can be achieved. The support rollers 15, 16 may be driven. Also, in addition to the in FIG. 1 shown support rollers 15, 16 may be provided a plurality of support rollers on one side of the lower processing unit. Instead of the support rollers and rigid elements can be provided over which slides a workpiece in the direction of passage.

Es ist jedoch ersichtlich, dass auch mehr als eine Stützrolle an jeder Seite des unteren Bearbeitungsaggregats 14 bereitgestellt werden kann, um ein Führen des Werkstücks im Bereich des unteren Bearbeitungsaggregats 14 zu ermöglichen. In anderen Ausführungsformen kann es auch geeignet sein, keine oder lediglich eine Stützrolle auf einer Seite neben dem Bearbeitungsaggregat 14 vorzusehen.It will be appreciated, however, that more than one support roller may be provided on each side of the lower processing assembly 14 to permit guiding of the workpiece in the region of the lower processing assembly 14. In other embodiments, it may also be suitable to provide no or only one support roller on one side adjacent to the processing unit 14.

Die Bearbeitung eines Werkstücks wird hierbei wie nachfolgend beschrieben durchgeführt. Ein Werkstück gelangt in den Einlaufbereich bzw. wird in den Einlaufbereich eingelegt, sodass es durch die zweite Förderbahn 10 und den ersten Rollenoberdruck 11 in Durchlaufrichtung bewegt wird. Hierbei wird durch die Verstellung der zweiten Förderbahn 10 durch den Höhenverstellmechanismus 3 in einer vertikalen Richtung die Abtragshöhe durch das untere Bearbeitungsaggregat 14 eingestellt. Der erste Rollenoberdruck 11 ist ebenfalls in einer vertikalen Richtung verstellbar, und kann an das zu bearbeitende Werkstück angepasst werden. Die Verstellung des zweiten Rollenoberdrucks berücksichtigt den beabsichtigten Abtrag durch die ersten Bearbeitungsaggregate 13 an der Oberseite des Werkstücks.The machining of a workpiece is carried out as described below. A workpiece enters the inlet region or is inserted into the inlet region, so that it is moved by the second conveyor track 10 and the first upper roll pressure 11 in the direction of passage.
