MASCHINE ZUM PROFILIEREN VON LÄNGLICHEN, PLATTENFÖRMIGEN WERKSTÜCKEN ENTLANG DER LÄNGSKANTENMACHINE FOR PROFILING LONG, PLATE-SHAPED WORKPIECES ALONG THE LENGTH EDGES
TECHNISCHES GEBIETTECHNICAL AREA
Die Erfindung bezieht sich auf eine Maschine zum Profilieren von länglichen, plattenförmigen Werkstücken aus Holz und/oder Holzersatzstoffen, wie Paneelen für Fußbodenbelä- ge, 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 Werkstü- cke in geradliniger Durchlaufrichtung, mit einer Profilierungszone, durch die hindurch sich die Fördervorrichtung erstreckt und in der zu beiden Seiten der Fördervorrichtung Bearbeitungsaggregate mit spannehmenden Profilierungswerk- zeugen angeordnet sind, und mit einer oberhalb der Förder- Vorrichtung 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 erstrecken- den 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 cladding, in the area of opposite longitudinal edges in a pass with a conveyor device for lying flat and on both sides with the Longitudinal edge areas protruding receiving the workpieces in a transport plane and for conveying the workpieces in a straight passage direction, with a profiling zone through which the conveying device extends and in which processing units with exciting profiling tools are arranged on both sides of the conveying device, and with one Above the conveying device, the workpieces on their upper pressure device acting on the side remote from the conveying device along the profiling zone, with an inlet zone in the direction of passage before the profiling zone with a stop ruler which extends in a straight line in the direction of passage for aligning the workpieces with one of their longitudinal edges on the direction of passage.
STAND DER TECHNIKSTATE OF THE ART
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 follows the entry zone with the stop ruler directly on the profiling zone with the profiling tools. The conveying device which extends through the profiling zone is extended towards the inlet side of the machine and thus also runs through the inlet zone without being covered here by the upper pressure device. The stop ruler is arranged laterally next to this area of the conveying device which is free at the top. The workpieces in the infeed zone are already placed on the conveyor device and guided along the stop ruler with one of their 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. Um Ungenauigkeiten zu vermindern, werden in der Profilierungszone die Profilierungswe kzeuge beidseits der Fördervor- richtung so einander gegenüberliegend angeordnet, daß sich die auf die Werkstücke ausgeübten Bearbeitungskräfte quer zur Durchlaufrichtung möglichst gegeneinander aufheben.The workpieces correspondingly aligned in the entry zone to the straight-line direction of passage with one of their longitudinal edges are clamped for the machining process in the profiling zone between the conveying device and the overpressure device as soon as the overpressure device has gripped the respective workpiece when passing from the entry zone into the profiling zone. The conveyor device is primarily a transport chain, the links of which are designed to absorb high compressive forces. The workpieces clamped between the conveying device and the top pressure device should not change their orientation during the profiling processes, so that the cut surfaces made by the profiling tools in the longitudinal edge region of the workpieces extend parallel to one another in the direction of passage. Around To reduce inaccuracies, the Profilierungswe tools are arranged on both sides of the conveyor opposite each other in the profiling zone so that the machining forces exerted on the workpieces cancel each other out as far as possible transversely to the direction of travel.
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 Fußbo- denpaneele, bei denen eine hohe Genauigkeit der Parallelität an ihren einander gegenüberliegenden, profilierten Längskantenbereichen gefordert wird.Nevertheless, such tolerances still occur on the finished workpieces that lead to disruptive protrusions, gaps or the like when the workpieces are installed. This is particularly the case with such panels with which a continuously flat surface must be achieved in the assembled state. This is especially true for floor panels, where high accuracy of parallelism is required on their opposing, 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 verwende- ten 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 Längskantenbe- reichen der Werkstücke führen.In the known throughfeed machines, the adherence to narrow tolerances on the machined workpieces reaches its limits because relative movements between the conveying device and the overpressure device can occur transversely to the conveying direction or throughput direction. This is because the chain 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, show a warpage along their length, which is why the longitudinal workpiece edge that runs along the stop ruler in the entry zone does not is exactly straight. Corresponding to the undefined system on the stop ruler, such a workpiece is clamped between the conveyor device and the top pressure device in the profiling zone in an undefined orientation. This can also contribute to machining inaccuracies that lead to disturbing deviations in the parallelism of the cut surfaces in the longitudinal edge areas of the workpieces to lead.
DIE ERFINDUNGTHE INVENTION
Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Ma- schine der eingangs genannten Art zu schaffen, mit der eine exaktere Parallelität der angearbeiteten Schnittflächen in den Längskantenbereichen der Werkstücke erzielt werden kann.The invention is therefore based on the object of creating a machine of the type mentioned at the outset with which a more precise parallelism of the cut surfaces in the longitudinal edge regions of the workpieces can be achieved.
Diese Aufgabe wird bei einer Maschine der vorgenannten Art durch die kennzeichnenden Merkmale des Patentanspruchs 1 gelöst.This object is achieved in a machine of the aforementioned type by the characterizing features of patent claim 1.
Für die Erfindung ist wesentlich, daß durch das Führungsli- neal, 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.It is essential for the invention that through 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 conveying device and the upper pressure device of the profiling zone from the guidance of the workpieces are exempt. The guide groove becomes exact in the entry zone Cut in the straight-line direction in which the guide rail is also located. This is ensured by the pressure device arranged in the infeed zone, which holds the workpieces in a constant orientation as they run along the stop ruler, in which orientation the workpieces are clamped between the overpressure device and the transport device of the infeed zone and are guided along the sawing device. There is therefore greater freedom in the choice of the conveyor device for the profiling zone, so even a slideway can be considered as the conveyor device, on which the workpieces are advanced by the top pressure device. For sensitive workpieces, the conveyor device of the profiling zone can alternatively consist of a conveyor belt which moves with its upper run 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 be- einträchtigt, 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. Dementsprechend ist die Sägevorrichtung obenliegend, nämlich im Bereich der Oberdruckeinrichtung der Einlaufzone angeordnet. Ebenso können die Werkstücke auch mit ihrer Gutseite nach oben hin liegend durch die Maschine hindurchlaufen, in diesem Fall ist die Sägevorrichtung im Bereich der Transporteinrichtung der Einlaufzone angeordnet und steht das zumindest eine Sägewerkzeug entsprechend der Nuttiefe über die Transportebene der Werkstücke vor. Bevorzugt besteht das Sägewerkzeug der Sägevorrichtung aus einem Kreissägeblatt, welches mit seiner Blattebene zum einen in der Durchlaufrichtung und zum anderen senkrecht zur Transport- ebene der Werkstücke steht.The workpieces to be machined with the continuous machine are already finished on their broad sides determined as visible sides. The workpieces accordingly have a good side, namely the surface-ready broadside, which must not be impaired, in particular not be damaged, during the machining process. So it goes without saying that the guide groove to be cut into the elongated workpieces is attached to the broad side of the workpieces remote from the good side. The workpieces can pass through the machine with their good side lying downwards, and accordingly the guide groove incised on the upper side of the workpiece. Accordingly, the sawing device is arranged on top, namely in the area of the upper pressure device of the inlet zone. Likewise, the workpieces can also run through the machine with their good side lying upwards, in this case the sawing device is arranged in the region of the transport device of the infeed zone and the at least one sawing tool projects beyond the transport plane of the workpieces according to the groove depth. The sawing tool of the sawing device preferably consists of a circular saw blade which, with its blade plane, is on the one hand in the direction of passage and on the other hand perpendicular to the transport plane of the workpieces.
Im übrigen ergeben sich vorteilhafte Ausgestaltungsmerkma- le der Erfindung aus den Unteransprüchen.For the rest, advantageous design features of the invention result from the subclaims.

WEG ZUR AUSFÜHRUNG DER ERFINDUNGWAY OF CARRYING OUT THE INVENTION
Im einzelnen zeigen die Figuren 1 und 2 ausgehend von der Einlaufseite der Durchlaufmaschine eine Einlaufzone 1, zu der hin mittels eines Hilfsförderers 2 Werkstücke 3 transportiert werden, bei denen es sich um längliche Paneele o- der brettförmige Gebildet handelt, wie sie insbesondere für Fußbodenbeläge im Innenausbau verwendet werden. Im Bereich der Einlaufzone 1 der Maschine werden die Werkstücke 3 auf einer Transporteinrichtung 4 flachliegend aufgenommen, wobei im vorliegenden Fall die sogenannte Gutseite der Werkstücke 3, also die oberflächenfertige Breitseite, nach unten hin liegt.In detail, FIGS. 1 and 2 show, starting from the infeed side of the continuous machine, an infeed zone 1, to which 2 workpieces 3 are transported by means of an auxiliary conveyor, which are elongate panels or board-shaped, as is particularly the case for floor coverings in Interior fittings can be used. In the area of the inlet zone 1 of the machine, the workpieces 3 are received lying flat on a transport device 4, in the present case the so-called good side of the workpieces 3, that is to say the surface-ready broadside, lying downward.
Die Transporteinrichtung 4 umfaßt einen Grundkörper 5, der an seiner Oberseite eine Gleitfläche 6 aufweist, über die hinweg ein umlaufendes Förderband 8 mit seinem Obertrum 7 gleitet. Die Förderrichtung der Transporteinrichtung 4 ent- spricht der geradlinien Durchlaufrichtung der gesamten Ma- schine. 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 transport device 4 comprises a base body 5, which has a sliding surface 6 on its upper side, over which a revolving conveyor belt 8 slides with its upper run 7. The conveying direction of the transport device 4 corresponds to the straight through direction of the entire dimension machine. To reduce the sliding friction, the upper run 7 of the conveyor belt 8 is blown out with supporting air; for this purpose, a plurality of air nozzles 9 are arranged in the area of the sliding surface 6 of the base body 5 in one or more rows lying in the direction of passage.
Auf dem Obertrum 7 des Transportbandes 8 werden die Werkstücke 3 mit einer ihrer Längskanten 3.1, siehe Fig. 3, auf die Durchlaufrichtung ausgerichtet. Hierzu ist seitlich neben dem Obertrum 7 des Transportbandes 8 der Transporteinrichtung 4 ein Anschlaglineal 10 angeordnet, dessen Anschlagfläche 10.1, siehe Fig. 3, sich geradlinig in der Durchlaufrichtung erstreckt.On the upper run 7 of the conveyor belt 8, the workpieces 3 are aligned with one of their longitudinal edges 3.1, see FIG. 3, in the direction of passage. For this purpose, a stop ruler 10 is arranged laterally next to the upper run 7 of the conveyor belt 8 of the transport device 4, the stop surface 10.1, see FIG. 3, extends in a straight line in the direction of passage.
Gegenüber dem Anschlaglineal 10 findet sich auf gleicher Höhe liegend eine Andruckvorrichtung 11, welche für eine Anlage der zu bearbeitenden Werkstücke 3 an der Anlageflä- ehe 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 Anschlagli- neal 10 abliegenden Längskanten der Werkstücke 3 und der Andruckvorrichtung 11 aufbaut, ein elastisches, nachgebendes Druckmittel erzeugt, welches auch aus einer mechani- sehen Einrichtung, wie einer federnd abgestützten Kufe gebildet sein kann.Opposite the stop ruler 10 there is a pressure device 11 lying at the same height, which ensures that the workpieces 3 to be machined abut against the contact surface 10.1 of the stop ruler 10. This is done by means of air which emerges from nozzles 12, which are at the level of the transported workpieces and are arranged in a plurality in succession in the direction of passage. The nozzles 12 of the pressing device 11 are at a distance from the longitudinal edge of the workpieces 3 running past them, which is accordingly only blown in such a way that the workpieces 3 easily contact the guide surface 10.1 of the stop ruler 10. This is in the form of an air cushion 13, which lies between the longitudinal edges of the workpieces 3 and the workpiece Pressure device 11 builds up, produces an elastic, yielding pressure medium, which can also be formed from a mechanical device, such as a resiliently supported runner.
In der Einlaufzone 1 ist oberhalb der Transporteinrichtung 4 eine Oberdruckeinrichtung 14 angeordnet, deren Anfang in Durchlaufrichtung gegenüber dem Anfang der Transporteinrichtung 4 versetzt ist. Die Oberdruckeinrichtung 14 besteht aus zwei umlaufenden Bändern 15, die, wie insbesondere Fig. 3 zeigt, mit ihren Untertrumen 15.1 die Werkstücke 3 erfassen und auf dem Obertrum 7 des Transportbandes 8 niederhalten. Entlang dem Wirkungsbereich der Oberdruckeinrichtung 14 sind somit die Werkstücke 3 in ihrer durch das Anschlaglineal 10 vorgegebenen Ausrichtung fixiert, und zwecks Sicherung der Lagefixierung der Werkstücke 3 erstrecken sich das Anschlaglineal 10 und die Andruckvorrichtung 11 in der Durchlaufrichtung noch über denjenigen Bereich hinaus, der von der Oberdruckeinrichtung 14 überdeckt wird.An overpressure device 14 is arranged in the inlet zone 1 above the transport device 4, the beginning of which is offset in the direction of passage in relation to the start of the transport device 4. The upper pressure device 14 consists of two peripheral belts 15 which, as shown in FIG. 3 in particular, grasp the workpieces 3 with their lower strands 15.1 and hold them down on the upper strand 7 of the conveyor belt 8. The workpieces 3 are thus fixed in their orientation predetermined by the stop ruler 10 along the effective range of the top pressure device 14, and in order to secure the position fixation of the workpieces 3, the stop ruler 10 and the pressing device 11 extend in the direction of passage beyond that area from the Upper pressure device 14 is covered.
In die Oberdruckeinrichtung 14 ist eine Sägevorrichtung 16 integriert, die Sägewerkzeuge 17 in Gestalt zweier • Säge-- blätter aufweist, die jeweils mit ihrer Blattebene zum einen in der Durchlaufrichtung liegen und zum anderen senkrecht zur Transportebene der Werkstücke 3 stehen. Wie sich weiter aus Fig. 4 ergibt, sind die zwei Bänder .15 der Oberdruckeinrichtung 14 beidseits an den Sägewerkzeugen 17 vor- beigeführt, um denjenigen Bereich an der obenliegenden Sei- te der Werkstücke 3 nicht zu beaufschlagen, in welchem die Sägewerkzeuge 17 eine in der Durchlaufrichtung sich erstre- ckende, also längslaufende Führungsnut 3.2, siehe .obere Darstellung von Fig. 4, eingeschnitten wird. Selbst wenn die Werkstücke 3 an ihrer am Anschlaglineal 10 anliegenden Längskante 3.1 einen gewissen Verzug aufweisen sollten, wird die längslaufende Führungsnut 3.2 exakt geradlinig in der Durchlaufrichtung liegend in die Werkstücke 3 eingeschnitten.A sawing device 16 is integrated into the top pressure device 14 and has sawing tools 17 in the form of two saw blades, each of which lies with its plane of the blade in the direction of passage and is perpendicular to the plane of transport of the workpieces 3. As can further be seen from FIG. 4, the two bands 15 of the top pressure device 14 are guided past the sawing tools 17 on both sides in order to cover the area on the upper side Te of the workpieces 3 not to be acted upon, in which the sawing tools 17 cut into a guide groove 3.2 which extends in the direction of passage, that is to say longitudinally, see upper illustration of FIG. 4. Even if the workpieces 3 should have a certain distortion on their longitudinal edge 3.1 lying against the stop ruler 10, the longitudinal guide groove 3.2 is cut into the workpieces 3 lying exactly straight in the direction of passage.
Von der Transporteinrichtung 4 und der Oberdruckeinrichtung 14 werden die mit der Führungsnut 3.2 versehenen Werkstücke 3 in der Durchlaufrichtung an eine weitere Fördervorrichtung 20 und eine Oberdruckvorrichtung 22 weitergegeben, wobei die Oberdruckvorrichtung 22, wie aus Fig. 5 hervorgeht, ebenfalls aus zwei umlaufenden Druckbändern 23 besteht, die mit ihren Untertrumen 23.1 die Werkstücke 3 an den obenlie- genden Seiten beaufschlagen. Diese Untertrume 23.1 der 0- berdruckvorrichtung 22 bewegen sich synchron mit den Untertrumen 15.1 der Bänder 15 der vorgeschalteten Oberdruckeinrichtung 14. Eine Besonderheit besteht insoweit darin, als die Oberdruckvorrichtung 22 zugleich auch den Vorschub der Werkstücke 3 entlang der Transportvorrichtung 20 besorgt, die nämlich aus einer Gleitbahn besteht. Im Bereich dieser Gleitbahn 20 werden die Werkstücke 3 mittels Stützluft unterblasen, und dazu sind in die Gleitbahn 20 Luftaustrittsdüsen 21 integriert, die in der Transport- bzw. Durchlaufrichtung hintereinander liegend in einer oder meh- reren Reihen angeordnet sind. Die Fördervorrichtung 20 und die zugehörige Oberdruckvorrichtung 22 erstrecken sich durch eine Profilierungszone 18 hindurch, in der die Werkstücke 3 in den Bereichen ihrer beidseits längslaufenden Kanten mit einer längslaufenden Profilierung versehen werden, die ähnlich einer Nut-Feder-Verbindung ein aneinander Anschließen benachbarter Werkstücke 3 beim Verbau am Einbauort erlauben. In Fig. 5 sind die längsseitigen Profilierungen an den Kanten des dargestellten Werkstückes mit 3.3 und 3.4 angedeutet. Angefahren werden die Profilierungen 3.3 und 3.4 an die Werkstücke 3 mittels ortsfest angeordneter Bearbeitungsaggregate mit rotierenden, spannehmen- den Profilierungswerkzeugen 19, und diese Bearbeitungsaggregate sind in der Profilierungszone 18 angeordnet.The workpieces 3 provided with the guide groove 3.2 are passed on by the transport device 4 and the upper pressure device 14 in the direction of passage to a further conveying device 20 and an upper pressure device 22, wherein the upper pressure device 22, as can be seen from FIG. 5, likewise consists of two rotating pressure belts 23 , which act on the workpieces 3 on the above sides with their sub-strands 23.1. These subspaces 23.1 of the overpressure device 22 move synchronously with the subspaces 15.1 of the belts 15 of the upstream upper pressure device 14. A special feature is that the upper pressure device 22 also simultaneously ensures the feed of the workpieces 3 along the transport device 20, namely from a Slideway exists. In the area of this slideway 20, the workpieces 3 are blown out by means of supporting air, and for this purpose air outlet nozzles 21 are integrated in the slideway 20, which are arranged one behind the other in the transport or passage direction in one or more directions. rere rows are arranged. The conveyor device 20 and the associated overpressure device 22 extend through a profiling zone 18, in which the workpieces 3 are provided with a longitudinal profiling in the regions of their longitudinal edges running on both sides, which, like a tongue and groove connection, connect adjacent workpieces 3 to one another Allow installation at the installation location. 5, the longitudinal profiles on the edges of the workpiece shown are indicated by 3.3 and 3.4. The profiles 3.3 and 3.4 are started on the workpieces 3 by means of stationary processing units with rotating, clamping profile tools 19, and these processing units are arranged in the profile zone 18.
In die Oberdruckvorrichtung 22 ist eine geradlinig sich in der Durchlaufrichtung erstreckende Führungsschiene 24 in- tegriert, die sich über die gesamte Länge der Profilierungszone 18 erstreckt. Beim Vorschub in die Profilierungszone 18 hinein schieben sich die Werkstücke 3 mit ihrer Führungsnut 3.2 auf die Führungsschiene 24 auf, womit quer zur Durchlaufrichtung die Werkstücke 3 sicher gehalten sind. Dementsprechend ist der Eingriffsquerschnitt der Führungsschiene 24 an den Querschnitt der Führungsnut 3.2 der Werkstücke 3 angepaßt. Zudem ist die Führungsschiene 24 so angeordnet, daß sie in der Durchlaufrichtung mit denjenigen Bereichen der Sägewerkzeuge 17 fluchtet,, die beim Anbringen der Führungsnuten 3.2 im Werkstückeingriff stehen. Die Werkstücke 3 haben eine solche Länge, daß beim Maschinen- durchlauf am vornliegenden Ende die Werkstücke mit ihrer Führungsnut 3.2 auf der Führungsschiene 24 bereits aufgenommen sind, während zum Ende eines Werkstücks hin die Sägevorrichtung 16 damit noch in Eingriff steht, um bis zum in Durchlaufrichtung rückwärtigen Ende des jeweiligen Werkstücks 3 die Führungsnut 3.2 daran fertigzuschneiden.A guide rail 24, which extends in a straight line in the direction of passage and extends over the entire length of the profiling zone 18, is integrated into the top pressure device 22. When feeding into the profiling zone 18, the workpieces 3 slide with their guide groove 3.2 onto the guide rail 24, with the workpieces 3 being held securely transversely to the direction of passage. Accordingly, the cross section of engagement of the guide rail 24 is adapted to the cross section of the guide groove 3.2 of the workpieces 3. In addition, the guide rail 24 is arranged such that it is aligned in the direction of travel with those areas of the sawing tools 17 which are in workpiece engagement when the guide grooves 3.2 are made. The Workpieces 3 are of such a length that when the machine passes through the leading end, the workpieces are already received with their guide groove 3.2 on the guide rail 24, while at the end of a workpiece the sawing device 16 is still in engagement with it, to the rear in the direction of the passage Finish cutting the guide groove 3.2 at the end of the respective workpiece 3.
Am Auslaufende der Fördervorrichtung 20 und der zugehörigen Oberdruckvorrichtung 22 werden die fertig bearbeiteten Werkstücke von einem weiteren Hilfsförderer 25 übernommen und abtransportiert. At the outlet end of the conveyor device 20 and the associated upper pressure device 22, the finished workpieces are taken over by a further auxiliary conveyor 25 and transported away.
