Description
Die Erfindung bezieht sich auf eine Maschine zum Profilieren von länglichen, plattenförmigen Werkstücken aus Holz und/oder Holzersatzstoffen, wie Paneelen für Fußbodenbeläge, Decken- oder Wandverkleidungen, im Bereich einander gegenüberliegender Längskanten im Durchlauf mit einer Fördervorrichtung zur flachliegenden sowie beidseits daran mit den Längskantenbereichen vorstehenden Aufnahme der Werkstücke in einer Transportebene und zum Befördern der Werkstücke in geradliniger Durchlaufrichtung, mit einer Profilierungszone, durch die hindurch sich die Fördervorrichtung erstreckt und in der zu beiden Seiten der Fördervorrichtung Bearbeitungsaggregate mit spannehmenden Profilierungswerkzeugen angeordnet sind, und mit einer oberhalb der Fördervorrichtung die Werkstücke an ihrer von der Fördervorrichtung abliegenden Seite entlang der Profilierungszone beaufschlagenden Oberdruckvorrichtung, wobei sich in der Durchlaufrichtung vor der Profilierungszone eine Einlaufzone mit einem in der Durchlaufrichtung geradlinig sich erstreckenden Anschlaglineal zum Ausrichten der Werkstücke mit einer ihrer Längskanten auf die Durchlaufrichtung befindet.The invention relates to a machine for profiling elongated, plate-shaped workpieces made of wood and / or wood substitutes, such as panels for floor coverings, ceiling or wall coverings, in the region of opposite longitudinal edges in the run with a conveyor for lying flat and both sides thereon with the longitudinal edge portions projecting Receiving the workpieces in a transport plane and for conveying the workpieces in a straight flow direction, with a profiling zone, through which the conveyor extends and are arranged on both sides of the conveyor processing units with exciting profiling tools, and with a above the conveyor to the workpieces their upstream of the conveying device side along the profiling zone acting on top pressure device, wherein in the passage direction in front of the profiling zone an inlet zone with a em in the direction of passage straight extending stop ruler for aligning the workpieces with one of its longitudinal edges is in the direction of passage.
Bei den bekannten Durchlaufmaschinen dieser Art schließt an die Einlaufzone mit dem Anschlaglineal unmittelbar die Profilierungszone mit den Profilierungswerkzeugen an. Die sich durch die Profilierungszone hindurch erstreckende Fördervorrichtung ist zur Einlaufseite der Maschine hin verlängert und verläuft somit auch durch die Einlaufzone hindurch, ohne hier nach oben hin von der Oberdruckvorrichtung überdeckt zu sein. Das Anschlaglineal ist seitlich neben diesem nach oben hin freien Bereich der Fördervorrichtung angeordnet. So werden die Werkstücke in der Einlaufzone bereits auf die Fördervorrichtung aufgegeben und entlang dem Anschlaglineal mit einer ihrer Längskanten geführt.In the known continuous machines of this type connects the inlet zone with the stop ruler directly to the profiling zone with the profiling tools. The conveying device extending through the profiling zone is lengthened toward the inlet side of the machine and thus also runs through the inlet zone without being covered here by the top pressure device. The stop ruler is arranged laterally next to this upwardly free region of the conveying device. Thus, the workpieces are already abandoned in the inlet zone on the conveyor and guided along the stop rule with one of its longitudinal edges.
Die dementsprechend in der Einlaufzone auf die geradlinige Durchlaufrichtung mit einer ihrer Längskanten ausgerichteten Werkstücke werden für den Bearbeitungsprozeß in der Profilierungszone zwischen der Fördervorrichtung und der Oberdruckvorrichtung verspannt, sobald beim Übertritt von der Einlaufzone in die Profilierungszone die Oberdruckvorrichtung das jeweilige Werkstück erfaßt hat. Bei der Fördervorrichtung handelt es sich vornehmlich um eine Transportkette, deren Glieder für die Aufnahme hoher Druckkräfte ausgelegt sind. Die zwischen der Fördervorrichtung und der Oberdruckvorrichtung verspannten Werkstücke sollen ihre Ausrichtung während der Profilierungsvorgänge nicht ändern, damit die von den Profilierungswerkzeugen im Längskantenbereich der Werkstücke angebrachten Schnittflächen sich miteinander parallel in der Durchlaufrichtung erstrecken. UmThe accordingly aligned in the inlet zone to the straight flow direction with one of its longitudinal edges workpieces are braced for the machining process in the profiling zone between the conveyor and the top pressure device when the top pressure device has detected the respective workpiece in the transition from the inlet zone into the profiling zone. The conveying device is primarily a transport chain whose links are designed to absorb high pressure forces. The clamped between the conveyor and the top pressure device workpieces should not change their orientation during the profiling operations, so that the cutting surfaces mounted by the profiling tools in the longitudinal edge region of the workpieces extend parallel to each other in the direction of passage. Around
Ungenauigkeiten zu vermindern, werden in der Profilierungszone die Profilierungswerkzeuge beidseits der Fördervorrichtung so einander gegenüberliegend angeordnet, daß sich die auf die Werkstücke ausgeübten Bearbeitungskräfte quer zur Durchlaufrichtung möglichst gegeneinander aufheben.To reduce inaccuracies, the profiling tools are arranged on both sides of the conveyor so opposite one another in the profiling zone, that abolish the forces exerted on the workpieces processing transverse to the direction of passage as possible against each other.
Dennoch treten an den fertig bearbeiteten Werkstücken immer noch solche Toleranzen auf, die beim Verbau der Werkstücke zu störenden Überständen, Spalten oder dergleichen führen. Dies ist insbesondere bei solchen Paneelen der Fall, mit denen im zusammengefügten Zustand eine durchgehend ebene Fläche erzielt werden muß. Dies gilt vor allem für Fußbodenpaneele, bei denen eine hohe Genauigkeit der Parallelität an ihren einander gegenüberliegenden, profilierten Längskantenbereichen gefordert wird.Nevertheless, such tolerances still occur on the finished workpieces which lead to disruptive projections, gaps or the like during the installation of the workpieces. This is especially the case with those panels with which a continuously flat surface must be achieved in the assembled state. This is especially true for floor panels, where a high accuracy of parallelism is required at their opposite, profiled longitudinal edge areas.
Bei den bekannten Durchlaufmaschinen stößt die Einhaltung enger Toleranzen an den bearbeiteten Werkstücken deshalb an Grenzen, weil zwischen der Fördervorrichtung und der Oberdruckvorrichtung Relativbewegungen quer zur Förderrichtung bzw. Durchlaufrichtung auftreten können. Dies liegt daran, daß die Kettenglieder einer als Fördervorrichtung verwendeten Kette zum Schlingern oder Gieren neigen, was sich mit zunehmendem Verschleiß verstärkt. Manche Werkstücke, solange sie noch unbearbeitet sind, weisen auf ihre Länge gesehen einen Verzug auf, weswegen die entlang dem Anschlaglineal in der Einlaufzone geführte Werkstücklängskante nicht exakt geradlinig ist. Entsprechend der dadurch undefinierten Anlage am Anschlaglineal wird ein solches Werkstück zwischen der Fördervorrichtung und der Oberdruckvorrichtung in der Profilierungszone in nicht definierter Ausrichtung verspannt, auch das kann zu Bearbeitungsungenauigkeiten beitragen, die zu störenden Abweichungen in der Parallelität der angearbeiteten Schnittflächen in den Längskantenbereichen der Werkstücke führen.In the known continuous machines, compliance with close tolerances on the machined workpieces therefore reaches its limits because relative movements between the conveying device and the top pressure device can occur transversely to the conveying direction or direction of passage. This is because the links of a chain used as a conveyor tend to roll or yaw, which increases with increasing wear. Some workpieces, as long as they are still unprocessed, have a delay in terms of their length, which is why the workpiece longitudinal edge guided along the stop ruler in the inlet zone does not is exactly straight. According to the thus undefined system on the stop rule such a workpiece between the conveyor and the top pressure device in the profiling zone is clamped in undefined orientation, which also can contribute to machining inaccuracies that lead to disturbing variations in the parallelism of the processed cut surfaces in the longitudinal edge regions of the workpieces.

Der Erfindung liegt die Aufgabe zugrunde, eine Maschine der eingangs genannten Art zu schaffen, mit der eine exakte Parallelität der angearbeiteten Schnittflächen in den Längskantenbereichen der Werkstücke erzielt werden kann.The invention has for its object to provide a machine of the type mentioned, with an exact parallelism of the processed cut surfaces in the longitudinal edge regions of the workpieces can be achieved.
Diese Aufgabe wird bei einer Maschine der vorgenannten Art durch die Merkmale des Patentanspruchs 1 gelöst.This object is achieved in a machine of the aforementioned type by the features of claim 1.
Für die Erfindung ist wesentlich, daß durch das Führungslineal, welches sich durch die Profilierungszone der Maschine hindurch erstreckt und welches in die in der Einlaufzone der Maschine in die Werkstücke eingeschnittene Führungsnut eingreift, die Fördervorrichtung und die Oberdruckvorrichtung der Profilierungszone von der Führung der Werkstücke befreit sind. Die Führungsnut wird in der Einlaufzone exakt in der geradlinigen Durchlaufrichtung eingeschnitten, in der sich auch die Führungsschiene befindet. Dafür sorgt die in der Einlaufzone angeordnete Andruckvorrichtung, welche die Werkstücke in gleichbleibender Ausrichtung beim Entlanglaufen an dem Anschlaglineal hält, wobei in dieser Ausrichtung die Werkstücke zwischen der Oberdruckeinrichtung und der Transporteinrichtung der Einlaufzone verspannt und entlang der Sägevorrichtung geführt werden. In der Wahl der Fördervorrichtung für die Profilierungszone hat man deshalb größere Freiheiten, so kann als Fördervorrichtung sogar eine Gleitbahn in Betracht kommen, auf der die Werkstücke durch die Oberdruckvorrichtung vorgeschoben transportiert werden. Für empfindliche Werkstücke kann die Fördervorrichtung der Profilierungszone alternativ aus einem Förderband bestehen, welches sich mit seinem Obertrum auf einer Gleitfläche bewegt.For the invention it is essential that the conveying device and the top pressure device of the profiling zone are freed from the guidance of the workpieces by the guide ruler which extends through the profiling zone of the machine and which engages in the guide groove cut into the workpieces in the inlet zone of the machine , The guide groove becomes exact in the inlet zone cut in the rectilinear passage direction in which the guide rail is located. This is ensured by the pressure device arranged in the inlet zone, which holds the workpieces in a constant orientation when they travel along the stop ruler, in which orientation the workpieces are clamped between the upper pressure device and the transport device of the inlet zone and guided along the sawing device. In the choice of the conveyor for the profiling zone therefore one has greater freedom, so can even be considered as a conveyor slideway on which the workpieces are transported advanced by the top pressure device. For sensitive workpieces, the conveying device of the profiling zone can alternatively consist of a conveyor belt which moves with its upper strand on a sliding surface.
Die mit der Durchlaufmaschine zu bearbeitenden Werkstücke sind an ihren als Sichtseiten bestimmten Breitseiten bereits oberflächenfertig ausgeführt. Die Werkstücke haben dementsprechend eine Gutseite, nämlich die oberflächenfertige Breitseite, die bei dem Bearbeitungsprozeß nicht beeinträchtigt, insbesondere nicht beschädigt werden darf. So versteht es sich, daß die in die länglichen Werkstücke einzuschneidende Führungsnut an der von der Gutseite abliegenden Breitseite der Werkstücke angebracht wird. Die Werkstücke können mit ihrer Gutseite nach unten hin liegend die Maschine durchlaufen, dementsprechend wird die Führungsnut an der obenliegenden Werkstückseite eingeschnitten.The workpieces to be processed with the continuous machine are already finished on their broad sides, which are intended as visible sides. The workpieces accordingly have a good side, namely the surface finished broadside, which does not affect the machining process, in particular may not be damaged. Thus, it is understood that the guide groove to be cut into the elongate workpieces is attached to the wide side of the workpieces remote from the good side. The workpieces can go through with their Gutseite lying down the machine, accordingly, the guide groove cut on the top side of the workpiece.
Bevorzugt besteht das Sägewerkzeug der Sägevorrichtung aus einem Kreissägeblatt, welches mit seiner Blattebene zum einen in der Durchlaufrichtung und zum anderen senkrecht zur Transportebene der Werkstücke steht.Preferably, the sawing tool of the sawing device consists of a circular saw blade, which stands with its leaf level on the one hand in the direction of passage and the other perpendicular to the transport plane of the workpieces.

Zur Verringerung der Gleitreibung wird das Obertrum 7 des Transportbandes 8 mit Stützluft unterblasen, dazu sind im Bereich der Gleitfläche 6 des Grundkörpers 5 eine Vielzahl von Luftdüsen 9 in einer oder mehrerer in Durchlaufrichtung liegenden Reihen angeordnet.The

Gegenüber dem Anschlaglineal 10 findet sich auf gleicher Höhe liegend eine Andruckvorrichtung 11, welche für eine Anlage der zu bearbeitenden Werkstücke 3 an der Anlagefläche 10.1 des Anschlaglineals 10 sorgt. Dies geschieht mittels Luft, die aus Düsen 12 austritt, welche in Höhe der transportierten Werkstücke liegen und in einer Vielzahl hintereinander in der Durchlaufrichtung angeordnet sind. Die Düsen 12 der Andruckvorrichtung 11 haben einen Abstand von der an ihnen vorbeilaufenden Längskante der Werkstücke 3, die entsprechend nur so angeblasen wird, daß die Werkstücke 3 sich ohne Zwang an die Führungsfläche 10.1 des Anschlaglineals 10 anlegen. So ist in Gestalt eines Luftpolsters 13, welches sich zwischen den von dem Anschlaglineal 10 abliegenden Längskanten der Werkstücke 3 und der Andruckvorrichtung 11 aufbaut, ein elastisches, nachgebendes Druckmittel erzeugt, welches auch aus einer mechanischen Einrichtung, wie einer federnd abgestützten Kufe gebildet sein kann.Opposite the
