Description

Die Erfindung bezieht sich auf eine Maschine zum Profilieren von einander gegenüberliegenden, miteinander parallelen Schmalflächenseiten plattenförmiger Werkstücke aus Holz und/oder Holzersatzstoffen, nämlich Paneelen für Fußbodenbeläge im Durchlaufverfahren gemäß den Merkmalen des Oberbegriffs des Patentanspruchs 1.The invention relates to a machine for profiling opposed, mutually parallel narrow sides of plate-shaped workpieces made of wood and / or wood substitutes, namely panels for floor coverings in a continuous process according to the features of the preamble of claim 1.

Eine solche Maschine ist aus dem Dokument DE 504 263 C bekannt. Bei dieser Maschine handelt es sich um eine Vierseiten-Hobelmaschine, die vornehmlich dazu dient, aus länglichen, eher lattenförmigen Werkstücken aus Holz Brettchen zu schneiden, die für die Parkettherstellung verwendet werden. Die Werkstücke durchlaufen hierbei eine Profilierungszone, in der die Gleitbahn für die Auflage der Werkstücke aus den Oberseiten zweier Kufen besteht, die an einer Auflageschiene nach oben hin vorstehen. Die Kufen greifen in zuvor von der Sägevorrichtung an der Auflageseite der Werkstücke eingeschnittene Nuten ein, womit bei der bekannten Maschine die Gleitbahn und die Geradführungseinrichtung von einer einzigen Vorrichtung gebildet sind. Für plattenförmige Werkstücke ist eine derartige Transport- und Führungsvorrichtung weniger geeignet, weil das Verhältnis zwischen den Gleitflächen und den Breitflächen der plattenförmigen Werkstücke ungünstig ist. Eine exakte Führung der Werkstücke bei zugleich geringstmöglicher Reibung läßt sich damit bei plattenförmigen Werkstücken nicht realisieren, dies vor allem dann nicht, wenn mit hohen Fördergeschwindigkeiten gearbeitet wird.Such a machine is from the document DE 504 263 C known. This machine is a four-sided planing machine, which is primarily used to cut long, rather slatted pieces of wood from boards that are used for parquet production. The workpieces pass through a profiling zone, in which the slideway for the support of the workpieces consists of the upper sides of two runners which project upwards on a support rail. The runners engage in previously cut by the sawing device on the support side of the workpieces grooves, which in the known machine, the slide and the linear guide device are formed by a single device. For plate-shaped workpieces, such a transport and guide device is less suitable because the ratio between the sliding surfaces and the wide surfaces of the plate-shaped workpieces is unfavorable. An exact guidance of the workpieces at the same time the lowest possible friction can not be realized with plate-shaped workpieces, this before especially not when working at high conveyor speeds.

Aus dem Dokument AT 263 335 C ist eine ähnliche Maschine bekannt, mit der längliche Werkstücke, wie paneelartige Holzleisten, an ihren einander gegenüberliegenden, miteinander parallelen Schmalflächenseiten profiliert werden. Auch hierbei werden die Werkstücke mittels Transportvorrichtungen zu der Profilierungszone hin und von dort wegbefördert und mittels einer Oberdruckvorrichtung beaufschlagt. Im Bereich der Profilierungszone sind Tische vorgesehen, auf denen die Werkstücke flachliegend gleiten.From the document AT 263 335 C A similar machine is known, with the elongated workpieces, such as panel-like wooden strips, are profiled at their opposite, mutually parallel narrow sides. Again, the workpieces are transported by means of transport devices to the profiling zone and away from there and acted upon by a top pressure device. In the area of the profiling zone tables are provided, on which the workpieces slide flat.

Aus dem Dokument FR-A-1 508 362 ist es des weiteren bekannt, bei holzbearbeitenden Hobelmaschinen mit Gleittischen in die Gleitbahn Luftaustrittsdüsen zum Ausblasen von Stützluft zu integrieren. Solche Tische, die als Luftkissentische bezeichnet werden, verringern den Gleitwiderstand zu den Werkstücken hin.From the document FR-A-1 508 362 It is also known to integrate in woodworking planing machines with slide tables in the slide air outlet nozzles for blowing out of supporting air. Such tables, referred to as air cushion tables, reduce the sliding resistance to the workpieces.

Der Erfindung liegt die Aufgabe zugrunde, eine Maschine der eingangs genannten Art zu schaffen, bei der die plattenförmigen Werkstücke möglichst reibungsarm durch die Profilierungszone hindurchtransportiert und exakt geführt werden, um die Parallelität der einander gegenüberliegenden, profilierten Schmalflächenseiten mit hoher Präzision und entsprechend geringen Toleranzen einhalten zu können.The invention has for its object to provide a machine of the type mentioned, in which the plate-shaped workpieces are transported as low friction through the profiling and accurately guided to comply with the parallelism of the opposite, profiled narrow sides with high precision and correspondingly low tolerances can.

Diese Aufgabe wird mit einer Maschine gelöst, welche die Gesamtheit der Merkmale des Patentanspruchs 1 aufweist.This object is achieved with a machine having the entirety of the features of claim 1.

Für die Erfindung ist wesentlich, daß die plattenförmigen Werkstücke beim Durchlauf durch die Profilierungszone nicht in seitlicher Richtung verlaufen können, also exakt durch das Zusammenspiel der an den Werkstücken angebrachten Führungsnut und der maschinenseitigen Geradführungseinrichtung in der vorgegebenen Durchlaufrichtung zwangsgeführt werden, in der bzw. parallel zu der die beidseitige Profilierung der Schmalflächenseiten der Werkstücke vorgenommen wird. Zwar muß die zumindest eine Führungsnut an den Werkstücken in einem separaten Arbeitsgang angebracht werden, auch muß dafür ein geeigneter Bereich an den Werkstücken gefunden werden, man erreicht jedoch ein wesentlich besseres Ergebnis gegenüber einer solchen Führung, bei der die Werkstücke während des Durchlaufs im Bereich ihrer in Durchlaufrichtung liegenden Schmalflächenseiten beaufschlagt werden. Denn die Führungsnuten werden dort an Stellen der Werkstücke angebracht, wo Bearbeitungen nicht oder nicht mehr vorgenommen werden. Zudem kann über die gesamte Länge der Werkstücke in der Durchlaufrichtung der führende Eingriff in die Führungsnuten erfolgen. In der Regel haben die Werkstücke in ihrer Durchlaufrichtung eine erhebliche Länge, wodurch eine besondere Führungssicherheit gegeben ist. Auch das Zusammenspiel zwischen der erfindungsgemäßen Führung der Werkstücke und deren Beförderung auf einer Gleitbahn ermöglicht den besonderen Vorteil, hohe Durchlaufgeschwindigkeiten bei der Profilierung der Werkstücke realisieren zu können.For the invention is essential that the plate-shaped workpieces can not run in the lateral direction when passing through the profiling zone, so are forcibly guided by the interaction of attached to the workpieces guide groove and the machine-side linear guide device in the predetermined direction of passage, in or parallel to the two-sided profiling of the narrow sides of the workpieces is made. Although the at least one guide must be attached to the workpieces in a separate operation, also a suitable area must be found on the workpieces, but one achieves a much better result over such a guide in which the workpieces during the passage in the area in the direction of passage lying narrow-surface sides are acted upon. Because the guide grooves are attached there to places of workpieces where processing is not or no longer made. In addition, over the entire length of the workpieces in the direction of passage of the leading engagement in the guide grooves take place. In general, the workpieces in their direction of passage have a considerable length, whereby a special leadership is given. The interaction between the inventive guidance of the workpieces and their transport on a slideway allows the particular advantage of high throughput speeds to realize in the profiling of the workpieces.

Bevorzugt wird die eine oder werden die mehreren Führungsnuten an derjenigen Breitflächenseite der Werkstücke eingeschnitten, die beim Durchlauf auf der Gleitbahn der Durchlaufmaschine aufliegt. Zweckmäßig wird der Einschnitt der Führungsnuten unmittelbar vor dem Profilierungsvorgang vor dem Auflaufen auf die maschinenseitige Geradführungsvorrichtung vorgenommen, womit sich bei fluchtender Ausrichtung des entsprechenden Bearbeitungswerkzeugs und der Geradführungseinrichtung eine weitere Ausrichtung der Werkstücke erübrigt. Die Führungsschiene ist segmentiert oder in einzelnen Abschnitten ausgeführt, die in Abstand voneinander angeordnet sind.Preferably, the one or more guide grooves are cut on that broad side of the workpieces, which rests on the slide of the continuous machine during the passage. Suitably, the incision of the guide grooves is made immediately before the profiling process before emergence on the machine-side Geradführungsvorrichtung, which is unnecessary in alignment alignment of the corresponding processing tool and the linear guide device further alignment of the workpieces. The guide rail is segmented or executed in individual sections, which are arranged at a distance from each other.

Ebenso wie der Transport auf der Gleitbahn erfolgt auch die Führung der Werkstücke mittels der Führungsnuten und der maschinenseitigen Geradführungseinrichtung gleitend. An den Werkstücken kann sich dies nicht nachteilig auswirken, weil sie die Durchlaufmaschine zur Profilierung an ihren Schmalflächenseiten nur einmal durchlaufen. Die Geradführungseinrichtung kann in ihrer feststehenden Anordnung aus einer durchgehenden Führungsschiene aus geeignetem Material bestehen, welches ausreichend widerstandsfähig ist, was aber nicht Teil der beanspruchten Erfindung ist. Erfindungs gemäß ist es vorgesehen, die Führungsschiene zu segmentieren oder auch in einzelnen Abschnitten auszuführen, die in Abstand voneinander angeordnet sind.As well as the transport on the slide and the leadership of the workpieces by means of the guide grooves and the machine-side linear guide device is carried out slidably. On the workpieces, this can not adversely affect because they pass through the continuous machine for profiling on their narrow sides only once. The straight guide device may consist in its fixed arrangement of a continuous guide rail of suitable material, which is sufficiently resistant, but which does not form part of the claimed invention. According to Invention, it is provided to segment the guide rail or to perform in individual sections, which are arranged at a distance from each other.

Die Erfindung wird nachfolgend anhand der Zeichnung noch näher erläutert. Dabei zeigen:

The invention will be explained in more detail with reference to the drawing. Showing:
Fig. 1

a schematic longitudinal section through the region of the machine according to FIG. 1 which is upstream of the profiling zone.

Im einzelnen erkennt man in Figur 1 eine Gleitbahn 1, die sich in der Durchlaufrichtung der Maschine erstreckt. Die Gleitbahn 1 hat hier zwei miteinander parallele in Abstand voneinander liegende Gleitflächen, die jeweils eben und die in der Regel horizontal ausgerichtet sind. Auf der Gleitbahn 1 werden in der Durchlaufrichtung Werkstücke 2 transportiert, die plattenförmig sind und bei denen es sich vornehmlich um längliche, brettartige Paneele handelt, aus denen ein Fußbodenbelag zusammengefügt wird. Die Gleitfähigkeit der Werkstücke 2 auf der Gleitbahn 1 wird durch ein Luftpolster von vernachlässigbarer Höhe begünstigt, und dazu sind in der Gleitbahn 1 in deren Ebene öffnende Luftauslaßdüsen 13 vorgesehen, über die die notwendige Stützluft zwischen die aufliegende Breitflächenseite der Werkstücke 2 und die Gleitbahn 1 eingeblasen wird. Das Entweichen der Stützluft bringt den weiteren Vorteil mit sich, daß die Förderrichtung der bei der Profilierung der Werkstücke 2 anfallenden Späne beeinflußt werden kann.In detail one recognizes in FIG. 1 a slideway 1 extending in the direction of travel of the machine. The slideway 1 here has two mutually parallel spaced-apart sliding surfaces, which are each planar and which are generally aligned horizontally. On the slide 1 workpieces 2 are transported in the direction of passage, which are plate-shaped and which are mainly oblong, board-like panels from which a floor covering is assembled. The slipperiness of the workpieces 2 on the slideway 1 is favored by an air cushion of negligible height, and for this purpose in the slideway 1 in the plane opening Luftauslaßdüsen 13 are provided, blown through the necessary supporting air between the overlying wide surface side of the workpieces 2 and the slide 1 becomes. The escape of the supporting air has the further advantage that the Conveying direction of the resulting in the profiling of the workpieces 2 chips can be influenced.

Der Vorschub der Werkstücke 2 auf der Gleitbahn 1 in der Durchlaufrichtung erfolgt mittels einer Oberdruckvorrichtung 3, 4. Diese Vorrichtung weist Förderriemen oder -gurte 3 auf, welche die von der Gleitbahn 1 abliegende, also oben liegende Breitflächenseite der Werkstücke 2 reibend beaufschlagen. Dazu sind entsprechende Führungs- und Andruckrollen 4 vorgesehen, die eine exakte Führung der Riemen 3 in der Durchlaufrichtung für die Werkstücke 2 sicherstellen.The feed of the workpieces 2 on the slide 1 in the passage direction by means of a top pressure device 3, 4. This device has conveyor belts or belts 3, which act rubbing the lying away from the slideway 1, so overhead lying broad side of the workpieces 2. For this purpose, corresponding guide and pinch rollers 4 are provided which ensure an exact guidance of the belt 3 in the direction of passage for the workpieces 2.

Die gesamte Anordnung ist auf einem Maschinengestell 5 aufgebaut, auf dem im Bereich einer Profilierungszone Profilierungsaggregate angeordnet sind, von denen in Figur 1 lediglich zwei einander gegenüber an den Werkstücken 2 angreifende Profilierungswerkzeuge 6 wiedergegeben sind. Diese Profilierungswerkzeuge 6 bearbeiten die sogenannten Schmalflächenseiten der plattenförmigen Werkstücke 2, wobei an der einen dieser Seiten beispielsweise eine Nut 7 und an der gegenüberliegenden Seite eine Feder 8 angebracht werden. Entsprechend handelt es sich bei den Werkzeugen 6 um rotierende Formwerkzeuge, wie Formfräser.The entire assembly is constructed on a machine frame 5 on which profiling units are arranged in the region of a profiling zone, of which in FIG. 1 only two opposite each other on the workpieces 2 attacking profiling tools 6 are shown. These profiling tools 6 process the so-called narrow-surface sides of the plate-shaped workpieces 2, wherein on one of these sides, for example, a groove 7 and on the opposite side a spring 8 are attached. Correspondingly, the tools 6 are rotating molds, such as form cutters.

Handelt es sich um Werkstücke 2, die im Bereich ihrer zu den Schmalflächenseiten hin liegenden Ränder Toleranzen aufweisen, wie es sich bei Werkstücken aus Holz oder holzartigen Werkstoffen in der Regel kaum vermeiden läßt, dann wird die randliche Höhenlage der Werkstücke 2 mittels Tastelementen 9 abgetastet, über deren Lageveränderung die Höhenausrichtung der Profilierungswerkzeuge 6 gesteuert wird.If it concerns workpieces 2, which have tolerances in the region of their lying on the narrow sides edges margins, as it can hardly be avoided in workpieces made of wood or wood-like materials, then the marginal altitude of the workpieces 2 is scanned by means of scanning elements 9, on the change in position, the height alignment of the profiling tools 6 is controlled.

Damit die Werkstücke 2 in der Durchlaufrichtung, die bei Figur 1 senkrecht zur Darstellungsebene verläuft, nicht verlaufen, also nicht quer zu der Durchlaufrichtung ausweichen können, wird an den Werkstücken 2 eine vorzugsweise mittig zur Längserstreckung verlaufende Führungsnut 10 angebracht, die auch in Figur 2 zu erkennen ist. Die Führungsnut 10 hat einander parallel gegenüberliegende Flanken, insbesondere hat sie einen rechteckförmigen Querschnitt. Angebracht wird diese Führungsnut 10 in einem Bereich der Maschine, der vor der Profilierungszone mit den Profilierungswerkzeugen 6 in der Durchlaufrichtung gesehen liegt. Dazu dient eine Sägevorrichtung 12, wie sie schematisch in Figur 2 wiedergegeben ist. Bei dem Bearbeitungswerkzeug dieser Sägevorrichtung 12 handelt es sich um zumindest ein Kreissägeblatt, dessen Ebene in der Durchlaufrichtung für die Werkstücke 2 liegt.So that the workpieces 2 in the passage direction, the at FIG. 1 runs perpendicular to the plane of representation, not running, so can not dodge transversely to the direction of passage, a preferably centrally extending to the longitudinal extension guide groove 10 is attached to the workpieces 2, which also in FIG. 2 can be seen. The guide groove 10 has mutually parallel flanks, in particular, it has a rectangular cross-section. This guide groove 10 is placed in an area of the machine that is seen in the direction of passage in front of the profiling zone with the profiling tools 6. For this purpose, a sawing device 12, as shown schematically in FIG FIG. 2 is reproduced. The machining tool of this sawing device 12 is at least one circular saw blade, the plane of which lies in the direction of passage of the workpieces 2.

Durch die Profilierungszone der Maschine hindurch, in der die Profilierungswerkzeuge 6 angeordnet sind, die sich beidseits der Gleitbahn 1 befinden, erstreckt sich eine Geradführungseinrichtung 11 in Gestalt einer Führungsschiene, die in einzelnen in Abstand voneinander liegenden Abschnitten ausgeführt ist, welche mit dem zumindest einen Kreissägeblatt der Sägevorrichtung 12 fluchtet. Zweckmäßig erstreckt sich die Geradführungseinrichtung 11 entgegen der Durchlaufrichtung bis zu der Sägevorrichtung 12 hin. Denn die Werkstücke 2 sollen mit ihren Führungsnuten 10 auf die Geradführungseinrichtung 11 auflaufen, also daran aufgenommen und geführt werden. Die Sägenvorrichtung 12 mit ihrem Kreissägeblatt liegt im Bereich der Gleitbahn 1, und das Kreissägeblatt der Sägenvorrichtung 12 steht darüber soweit vor, wie es der Tiefe der in die unten liegenden Breitflächenseiten der Werkstücke 2 einzuschneidenden Führungsnuten 10 entspricht. Ebenso steht auch die Geradführungseinrichtung 11 über die Gleitbahn 1 nach oben hin vor, der Überstand ist jedoch etwas geringer als die Tiefe der in die unten liegenden Seiten der Werkstücke 2 eingeschnittenen Führungsnuten 10. In der Durchlaufrichtung fluchtet die Geradführungseinrichtung 11 mit der Sägenvorrichtung 12, so daß über die Oberdruckvorrichtung 3, 4 die Werkstücke 2 über die Sägenvorrichtung 12 hinweg in die Profilierungszone befördert werden, wobei kurz hinter der Sägenvorrichtung 12 die Geradführungseinrichtung 11 in Eingriff mit den Führungsnuten 10 der Werkstücke 2 kommt.Through the profiling zone of the machine, in which the profiling tools 6 are arranged, which are located on both sides of the slideway 1, a straight guide device 11 extends in the form of a guide rail, which is executed in individual spaced sections, which with the at least one circular saw blade the sawing device 12 is aligned. Expediently, the straight guide device 11 extends counter to the passage direction as far as the sawing device 12. Because the workpieces 2 should accrue with their guide grooves 10 on the Geradführungseinrichtung 11, so it is recorded and guided. The sawing device 12 with its circular saw blade lies in the region of the slide track 1, and the circular saw blade of the sawing device 12 projects beyond as far as corresponds to the depth of the guide grooves 10 to be cut into the lower broad-side sides of the workpieces 2. Likewise, the straight guide device 11 protrudes upwards over the slide track 1, but the projection is somewhat smaller than the depth of the guide grooves 10 cut into the lower sides of the workpieces 2. In the passage direction, the straight guide device 11 is aligned with the saw device 12, see FIG in that the workpieces 2 are conveyed over the saw device 12 into the profiling zone via the top pressure device 3, 4, the straight guide device 11 coming into engagement with the guide grooves 10 of the workpieces 2 shortly behind the saw device 12.

Die Breite der Geradführungseinrichtung 11 quer zur Durchlaufrichtung ist zumindest im Bereich der Profilierungszone mit engen Toleranzen an die Weite der Führungsnuten 10 der Werkstücke 2 angepaßt. Damit werden die Werkstücke 2 so gut wie spielfrei quer zur Durchlaufrichtung im Bereich der Profilierungszone geführt. Vor allem können die Werkstücke 2 nicht dem Bearbeitungsdruck nachgeben, der quer zur Durchlaufrichtung von den Profilierungswerkzeugen 6 auf sie ausgeübt wirdThe width of the straight guide device 11 transversely to the passage direction is adapted at least in the region of the profiling zone with narrow tolerances to the width of the guide grooves 10 of the workpieces 2. Thus, the workpieces 2 are performed as well as backlash transversely to the direction of passage in the profiling zone. Above all, the workpieces can 2 do not yield to the processing pressure which is exerted transversely to the passage direction of the profiling tools 6 on them
