Die in Figur 1 in einer Perspektive schematisch dargestellte Holzbearbeitungsanlage ist insbesondere für eine 6-Seiten-Bearbeitung von länglichen Werkstücken 1 wie Holzbalken, Brettern, Platten und dgl. konzipiert. Sie enthält eine hier als Rollenbahn ausgeführte Werkstückauflage 2 mit einem in Transportrichtung gesehen vorderen Auflagebereich 2a und einem vom vorderen Auflagebereich 2a beabstandeten hinteren Auflagebereich 2b. Zwischen dem vorderen und hinteren Auflagebereich 2a und 2b der Werkstückauflage 2 ist ein im Folgenden noch näher erläutertes Bearbeitungsaggregat 3 angeordnet. Die vorderen und hinteren Auflagebereiche 2a und 2b enthalten in an sich bekannter Weise eine Vielzahl hintereinander angeordneter Transportrollen 4, die zwischen parallelen Schienen 5 drehbar gelagert sind. Die Schienen 5 mit den dazwischen drehbar gelagerten Transportrollen 4 sind auf einem hier als Schweißkonstruktion ausgeführten Gestell 6 angeordnet. Die vorderen und hinteren Auflagebereiche 2a und 2b können einen festen Abstand aufweisen. Mindestens einer der beiden Auflagebereiche 2a, 2b kann aber auch horizontal in Richtung der ersten Linearachse (X-Achse) verstellt werden, so dass die Werkstückauflage möglichst nahe am Werkzeug erfolgen kann. Die Holzbearbeitungsanlage enthält außerdem eine Transporteinrichtung 7, mit der ein auf der Werkstückauflage 2 liegendes Werkstück 1 relativ zur Werkstückauflage 2 und zum Bearbeitungsaggregat 5 in Richtung einer ersten Linearachse (X-Achse) horizontal verschoben werden kann.

The woodworking plant shown schematically in Figure 1 in a perspective is in particular for a 6-sided machining of elongated workpieces 1 such as wooden beams, boards, plates and Like. Conceived. It contains a workpiece support 2 designed here as a roller conveyor with a front support region 2a in the transport direction and a rear support region 2b spaced from the front support region 2a. Between the front and rear bearing region 2a and 2b of the workpiece support 2, a processing unit 3, which will be explained in greater detail below, is arranged. The front and rear support areas 2a and 2b contain in a conventional manner a plurality of successively arranged transport rollers 4, which are rotatably mounted between parallel rails 5. The rails 5 with the transport rollers 4 rotatably mounted therebetween are arranged on a frame 6 designed here as a welded construction. The front and rear bearing portions 2a and 2b may have a fixed distance.

An einer vorderen Stirnseite 20 des zwischen den vorderen und hinteren Auflagebereich 2a und 2b ragenden vorderen Endes des horizontalen Trägers 15 ist ein horizontal auskragendes vorderes Trägerteil 21 um eine zu der ersten Linearachse (X-Achse) rechtwinklige erste Drehachse (A- Achse) drehbar angeordnet. Das Trägerteil 21 ist als ein von der vorderen Stirnseite 20 vorstehender horizontaler Stützkörper mit einer zur ersten Drehachse (A- Achse) parallelen Abstützfläche 22 ausgeführt. Auf der Abstützfläche 22 des vorderen Trägerteils 21 ist ein winkelförmiger Arm 23 um eine zur ersten Drehachse (A- Achse) rechtwinklige zweite Drehachse (B- Achse) um 360° schwenkbar angeordnet. Der winkelförmige Arm 23 weist einen auf der Abstützfläche 22 des vorderen Trägerteils 21 aufliegenden unteren Schenkel 24 und ein dazu rechtwinkliges, von dem Trägerteil 21 seitlich auskragendes Stützteil 25 mit einer inneren Anlagefläche 26 auf. At a front end face 20 of the front end of the horizontal support 15 projecting between the front and rear support portions 2a and 2b, a horizontally cantilevered front support part 21 is rotatably disposed about a first rotation axis (A axis) perpendicular to the first linear axis (X axis) , The carrier part 21 is designed as a horizontal supporting body projecting from the front end side 20 with a supporting surface 22 parallel to the first axis of rotation (A axis). On the support surface 22 of the front support member 21, an angle-shaped arm 23 is pivotable about 360 ° about a second rotation axis (B axis) perpendicular to the first rotation axis (A axis). The angular arm 23 has a resting on the support surface 22 of the front support member 21 lower leg 24 and a rectangular thereto, laterally projecting from the support member 21 support member 25 with an inner abutment surface 26.
An dem freien Ende des um die zweite Drehachse (B-Achse) ebenfalls motorisch schwenkbaren Arms 23 ist die als Motorspindel ausgebildete Bearbeitungseinheit 13 um eine von der ersten Drehachse (A-Achse) beabstandete und zur zweiten Drehachse (B-Achse) rechtwinklige dritte Drehachse (C-Achse) drehbar angeordnet. Die Bearbeitungseinheit 13 ist an der zur Abstützfläche 22 rechtwinkligen inneren Anlagefläche 26 des Stützteils 25 angeordnet. Über den winkelförmigen Arm 23 mit dem von dem vorderen Trägerteil 21 rechtwinklig auskragenden Stützteil 25 ist die dritte Drehachse (C-Achse) parallel zu der ersten Drehachse (A- Achse) angeordnet. Die Bearbeitungseinheit 13 ist über einen Motor um die dritte Drehachse (C-Achse) drehbar. Sämtliche Antriebsmotoren sind gesteuert, so dass die Bearbeitungseinheit 13 eine gesteuerte Bewegung gegenüber dem Werkstück 1 ausführen kann. In die um die Werkzeugdrehachse D motorisch drehbare Werkzeugaufnahme 14 der Bearbeitungseinheit 13 kann ein Fräser, ein Bohrer, eine Säge oder ein anderes geeignetes Werkzeug eingespannt sein. Die Werkzeugdrehachse D ist rechtwinklig zur dritten Drehachse (C-Achse) ausgerichtet. At the free end of the about the second axis of rotation (B-axis) also motor pivotable arm 23 is designed as a motor spindle machining unit 13 about one of the first axis of rotation (A-axis) spaced and the second axis of rotation (B-axis) right-angle third axis of rotation (C-axis) rotatably arranged. The processing unit 13 is arranged at the support surface 22 perpendicular to the inner bearing surface 26 of the support member 25. About the angle-shaped arm 23 with the right of the front support member 21 projecting support member 25, the third axis of rotation (C-axis) is arranged parallel to the first axis of rotation (A axis). The processing unit 13 is rotatable about a motor about the third axis of rotation (C-axis). All drive motors are controlled so that the processing unit 13 can perform a controlled movement relative to the workpiece 1. A milling cutter, a drill, a saw or another suitable tool can be clamped in the tool holder 14 of the machining unit 13, which can be rotated by a motor about the tool rotational axis D. The tool rotation axis D is aligned at right angles to the third axis of rotation (C axis).
Der Träger 15 ist mit seinem gegenüber dem Vertikalträger 19 auskragenden vorderen Ende zwischen dem vorderen und hinteren Auflagerbereich 2a und 2b auch über und unter dem Werkstück 1 so verfahrbar, dass die in drei Achsen drehbare Bearbeitungseinheit 15 mit dem Werkzeug 16 zu allen Seiten des Werkstücks gelangt. So kann z.B. neben der Ober- und Unterseite des Werkstücks auch die Hinter- und Vorderseite des Werkstücks 1 bearbeitetet werden. Auch die beiden Stirnseiten des Werkstücks 1 können bearbeitet werden. Durch die vorstehend beschriebenen Bewegungsmöglichkeiten im mehreren Achsen kann somit das durch die Transporteinrichtung transportierte Werkstück 1 ohne Umkanten auf allen sechs Seiten bearbeitet werden. The support 15 is movable above and below the workpiece 1 with its front end projecting relative to the vertical support 19 between the front and rear support regions 2a and 2b such that the machining unit 15 rotatable in three axes reaches the workpiece 16 on all sides of the workpiece , Thus, e.g. In addition to the top and bottom of the workpiece and the back and front of the workpiece 1 are edited. Also, the two end faces of the workpiece 1 can be edited. As a result of the above-described possibilities of movement in several axes, the workpiece 1 transported by the transport device can thus be processed without being edged on all six sides.
