Description

Die Erfindung betrifft eine Andruckeinrichtung für eine Be­arbeitungsmaschine, vorzugsweise eine Holzbearbeitungs­maschine, insbesondere eine Kehlmaschine, nach dem Oberbe­griff des Ansprüches 1.The invention relates to a pressure device for a processing machine, preferably a woodworking machine, in particular a moulder, according to the preamble of claim 1.

Bei Holzbearbeitungsmaschinen befindet sich in Transportrichtung der zu bearbeitenden Werkstücke vor dem jeweiligen Bear­beitungswerkzeug ein Andruckelement in Form eines Andruck­schuhs, das die zu bearbeitenden Werkstücke beim Transport durch die Maschine gegen eine entsprechende Führung bzw. Auf­lage drückt. Das Andruckelement muß in einem bestimmten Ab­ stand zum Flugkreis des Bearbeitungswerkzeuges angeordnet werden, um eine optimale Wirkung auszuüben. Wird das Be­arbeitungswerkzeug gegen ein anderes Bearbeitungswerkzeug mit einem anderen Flugkreisdurchmesser ausgetauscht, dann muß das Andruckelement in einem aufwendigen Arbeitsverfahren ver­stellt werden. Dabei muß das Andruckelement nicht nur in Horizontal-, sondern auch in Vertikalrichtung neu einge­stellt werden. Diese umständliche Verstellung ist nicht nur aufwendig und schwierig, sondern auch zeitaufwendig.In woodworking machines there is a pressure element in the form of a pressure shoe in the direction of transport of the workpieces to be machined, which presses the workpieces to be machined against a corresponding guide or support during transport through the machine. The pressure element must in a certain Ab Stand to the flight circle of the processing tool to be optimally effective. If the processing tool is exchanged for another processing tool with a different flight circle diameter, then the pressure element must be adjusted in a complex working process. The pressure element must be readjusted not only in the horizontal but also in the vertical direction. This cumbersome adjustment is not only complex and difficult, but also time-consuming.

Der Erfindung liegt die Aufgabe zugrunde, die gattungsge­mäße Andruckeinrichtung so auszubilden, daß das Andruckele­ment einfach und innerhalb kürzester Zeit relativ zum Be­arbeitungswerkzeug verstellt werden kann.The invention has for its object to design the generic pressure device so that the pressure element can be easily and relatively quickly adjusted relative to the machining tool.

Diese Aufgabe wird bei der gattungsgemäßen Andruckeinrichtung erfindungsgemäß mit den kennzeichnenden Merkmalen des An­spruches 1 gelöst.This object is achieved in the generic pressure device according to the invention with the characterizing features of claim 1.

Bei der erfindungsgemäßen Andruckeinrichtung läßt sich das Andruckelement in nur einem einzigen Verstellvorgang gleich­zeitig horizontal und vertikal verstellen, da es schräg zur Transportrichtung der Werkstücke gegenüber dem Bearbeitungs­werkzeug verstellt wird. Die Verstellrichtung oder Verstell­ebene des Andruckelementes wird hierbei so vorgesehen, daß das Andruckelement bei Bearbeitungswerkzeugen mit unter­schiedlichen Flugkreisdruchmessern jeweils in eine zumindest angenähert optimale Lage zum Bearbeitungswerkzeug gebracht wird. Die Verstellung des Andruckelementes läßt sich ein­fach und vor allen Dingen äußerst zeitsparend durchführen. Weitere Merkmale der Erfindung ergeben sich aus den weiteren Ansprüchen, der Beschreibung und den Zeichnungen.In the pressure device according to the invention, the pressure element can be adjusted horizontally and vertically at the same time in a single adjustment process, since it is adjusted obliquely to the direction of transport of the workpieces relative to the processing tool. The adjustment direction or adjustment plane of the pressure element is provided in such a way that the pressure element in processing tools with different flight circle diameters is brought into an at least approximately optimal position relative to the processing tool. The adjustment of the pressure element can be carried out easily and, above all, extremely time-saving. Further features of the invention result from the further claims, the description and the drawings.

  • Fig. 1 teilweise im Schnitt und teilweise in Seitenansicht eine erfindungsgemäße Andruckeinrichtung einer Holzbe­arbeitungsmaschine,
  • Fig. 2 in schematischer und perspektivischer Darstellung einen Teil der Andruckeinrichtung gem. Fig. 1.
The invention is explained in more detail using an exemplary embodiment shown in the drawings. Show it
  • 1 partially in section and partially in side view of a pressure device according to the invention of a woodworking machine,
  • Fig. 2 in a schematic and perspective view of part of the pressure device acc. Fig. 1.

Die Andruckeinrichtung ist bei einer Holzbearbeitungsmaschine, vorzugsweise einer Kehlmaschine, vorgesehen und im Bereich der Bearbeitungswerkzeuge dieser Holzbearbeitungsmaschine ange­ordnet. Fig. 1 zeigt als Holzbearbeitungswerkzeug einen Messerkopf 1, der um eine horizontale Achse 2 drehbar ange­trieben wird. Längs seines Umfanges ist der Messerkopf 1 mit (nicht dargestellten) Messern versehen, mit denen die in Pfeil­richtung 3 unterhalb des Messerkopfes vorbeigeführten Hölzer bearbeitet werden. Die beim Bearbeiten der Hölzer anfallenden Späne werden von der Absaughaube 4 entfernt, die den Messer­kopf überdeckt. Die Absaughaube 4 ist auf einem Träger 5 be­festigt, der auf einer Schwenkachse 6 gelagert ist. Sie ist in Seitenwänden 7 einer Abdeckhaube 8 schwenkbar gelagert. Der Träger 5 ist gabelförmig ausgebildet und hat zwei Schen­kel 9 und 10, mit denen er auf der Schwenkachse 6 sitzt. Beide Schenkel 9, 10 sind durch einen Querträger 11 mitein­ander verbunden, dessen von der Schwenkachse 6 abgewandte Oberseite 12 (Fig. 1) eine Bezugs- und Verstellfläche für die Absaughaube 4 bildet. Sie hat einen auf der Oberseite 12 des Querträgers 11 aufliegenden Verstellteil 13, der winklig von der Wandung des Absaugkanals 14 absteht. Vorzugsweise ist der Verstellteil 13 - ebenso wie der Querträger 11 - plattenförmig ausgebildet. Er ist mit in Fig. 1 nur ange­deuteten Schrauben 15 auf dem Querträger 11 befestigt. Im Verstellteil 13 sind für den Durchtritt der Schrauben 15 (nicht dargestellte) Langlöcher vorgesehen, die sich senkrecht zur Längsrichtung des Verstellteils 13 bzw. des Querträgers 11 bzw. zur Drehachse 2 des Messerkopfes 1 erstrecken. Diese Langlöcher sind vorgesehen, um die Absaughaube 4 zur An­passung an im Duchmesser unterschiedlich große Messerköpfe 1 relativ zum Träger 5 nach Lockern der Schrauben 15 ver­stellen zu können. Für diesen Verstellvorgang ist am Ver­stellteil 13 eine Verstellspindel 16 gelagert, die mit einem Griff 17 gedreht werden kann. Die Verstellspindel 16 ragt durch einen quer vom Verstellteil 13 abstehenden Lagerteil 18 und ist im Querträger 11 gehalten.The pressure device is provided in a woodworking machine, preferably a moulder, and is arranged in the area of the processing tools of this woodworking machine. 1 shows, as a woodworking tool, a cutter head 1 which is rotatably driven about a horizontal axis 2. Along its circumference, the cutter head 1 is provided with knives (not shown) with which the woods which are passed in the direction of the arrow 3 below the cutter head are processed. The chips generated when processing the wood are removed from the suction hood 4, which covers the cutter head. The suction hood 4 is fastened on a carrier 5 which is mounted on a pivot axis 6. It is pivotally mounted in side walls 7 of a cover 8. The carrier 5 is fork-shaped and has two legs 9 and 10 with which it sits on the pivot axis 6. Both legs 9, 10 are connected to one another by a cross member 11, the upper side 12 (FIG. 1) facing away from the pivot axis 6 forms a reference and adjustment surface for the suction hood 4. It has one on the top 12 of the Cross member 11 resting adjustment part 13 which protrudes at an angle from the wall of the suction channel 14. Preferably, the adjustment part 13 - like the cross member 11 - is plate-shaped. It is fastened to the cross member 11 with screws 15, which are only indicated in FIG. 1. In the adjustment part 13, elongated holes (not shown) are provided for the passage of the screws 15, which extend perpendicular to the longitudinal direction of the adjustment part 13 or the cross member 11 or to the axis of rotation 2 of the cutter head 1. These elongated holes are provided in order to be able to adjust the suction hood 4 relative to the carrier 5 after loosening the screws 15 in order to adapt to cutter heads 1 of different diameters. For this adjustment process, an adjustment spindle 16 is mounted on the adjustment part 13 and can be rotated with a handle 17. The adjusting spindle 16 projects through a bearing part 18 projecting transversely from the adjusting part 13 and is held in the cross member 11.

An der in Transportrichtung 3 rückwärtigen Wand 19 der Absaug­haube 4 ist ein Andruckelement 20 in Form eines Andruckschuhs gelagert. Er hat eine in Transportrichtung 3 nach vorn und unten geneigte Andrückfläche 21, auf die die zu bearbeitenden Hölzer beim Transport in Pfeilrichtung 3 vor dem Messerkopf 2 auflaufen und bei der Bearbeitung gegen die (nicht darge­stellte) Transportbahn der Holzbearbeitungsmaschine gedrückt werden. Das Andruckelement 20 hat an seiner in Transportrichtung 3 der Hölzer vorderen Seite eine Spitze bzw. Kante 22, die in bekannter Weise einen vorgegebenen Abstand zum Flugkreis des Messerkopfes 1 hat. Das Andruckelement 20 ist um eine Achse 23 begrenzt schwenkbar an der Absaughaube 4 gelagert. Fig. 1 zeigt das Andruckelement 20 in seiner Endlage, in die es durch eine (nicht dargestellte) Feder gedrückt wird. Das Andruckelement 20 hat nur einen verhältnismäßig geringen Schwenkweg, um die Andrückwirkung auf die zu bearbeitenden Hölzer nicht zu beeinträch­tigen. Durch die Feder wird das Andruckelement 20 in Richtung auf den Messerkopf 1 belastet. Hat das zu bearbeitende Holz größere Dickendifferenzen, dann kann das Andruckelement 20 gegen die Federkraft geringfügig gegenüber der Absaughaube 4 verschwenkt werden. Es hat sich gezeigt, daß durch diese Dämpfungseinrichtung zuverlässig verhindert wird, daß die gesamte Absaughaube 4 in Schwingungen bzw. Vibrationen ge­rät. Die Absaughaube 4 mit dem Träger 5 selbst ist ebenfalls in bekannter Weise federbelastet, so daß diese Teile bei größeren Dickendifferenzen des zu bearbeitenden Holzes eben­falls wegschwenken können. Die Federkraft der Absaughaube und des Trägers ist jedoch wesentlich größer als die Feder­kraft des Andruckelementes 20. Dadurch wird bei kleineren Dickendifferenzen der zu bearbeitenden Hölzer lediglich das Andruckelement 20 weggeschwenkt, ohne daß sich dies auf die Absaughaube 4 auswirkt. Infolge dieser Ausbildung wird eine erhebliche Geräuschdämpfung beim Bearbeiten der Hölzer er­reicht, weil die Absaughaube 4 mit dem Träger 5 ruhig steht und sich allenfalls das Andruckelement 20 gegenüber der Ab­saughaube 4 bewegt.A pressure element 20 in the form of a pressure shoe is mounted on the rear wall 19 of the suction hood 4 in the transport direction 3. It has a pressing surface 21 which is inclined forward and downward in the transport direction 3, onto which the woods to be processed run in front of the cutter head 2 in the direction of arrow 3 and are pressed against the transport path (not shown) of the woodworking machine during processing. The pressure element 20 has a tip or edge 22 on its front side in the direction of transport 3 of the wood, which has a predetermined distance from the flight circle of the cutter head 1 in a known manner. The pressure element 20 is pivotally supported on the suction hood 4 to a limited extent about an axis 23. Fig. 1 shows the pressure element 20 in its end position, in which it is pressed by a spring (not shown). The pressure element 20 has only a relatively small swivel path, so as not to impair the pressure effect on the wood to be processed. The pressure element 20 is loaded in the direction of the cutter head 1 by the spring. If the wood to be processed has greater differences in thickness, then the pressure element 20 can be pivoted slightly against the suction hood 4 against the spring force. It has been shown that this damping device reliably prevents the entire exhaust hood 4 from oscillating or vibrating. The suction hood 4 with the carrier 5 itself is also spring-loaded in a known manner, so that these parts can also pivot away in the case of larger differences in thickness of the wood to be processed. The spring force of the suction hood and the carrier is, however, considerably greater than the spring force of the pressure element 20. As a result, in the case of smaller thickness differences of the woods to be processed, only the pressure element 20 is pivoted away without this having an effect on the suction hood 4. As a result of this design, considerable noise reduction is achieved when processing the woods, because the suction hood 4 is stationary with the support 5 and at most the pressure element 20 moves relative to the suction hood 4.

Je nach Flugkreisdurchmesser des eingesetzten Messerkopfes 1 muß die Kante 22 des Andruckelementes 20 relativ zum Flug­kreis eingestellt werden, um eine optimale Wirkung zu erzielen. Um diese Verstellung zu ermöglichen, ist es lediglich not­wendig, die Schrauben 15 zu lockern und dann mit der Ver­stellspindel 16 die Absaughaube 4 mit dem daran gelagerten Andruckelement 20 gegenüber dem Träger 5 zu verstellen. Die Oberseite 12 des Querträgers 11 des Trägers 5 erlaubt hierbei eine genaue und exakte Verstellung des Andruckelements 20.Depending on the flight circle diameter of the cutter head 1 used, the edge 22 of the pressure element 20 must be adjusted relative to the flight circle in order to achieve an optimal effect. In order to make this adjustment possible, it is only necessary to loosen the screws 15 and then to use the adjusting spindle 16 to adjust the suction hood 4 with the pressure element 20 mounted thereon relative to the carrier 5. The upper side 12 of the cross member 11 of the carrier 5 allows an accurate and exact adjustment of the pressure element 20.

Die Oberseite 12 ist unter einem solchen Winkel zur Horizon­talen geneigt, daß bei einem Verschieben der Absaughaube 4 in Pfeilrichtung 24 die Kante 22 nicht nur horizontal, sondern gleichzeitig auch vertikal zum Messerkopf 1 verstellt wird. Je nach Flugkreisdurchmesser muß die Kante 22 nicht nur in Horizontalrichtuug, sondern auch in Vertikalrichtung verstellt werden. Infolge der Schräglage der Oberseite 12 ist für diese beiden Verstellungen nur ein einziger Verstellvorgang notwen­dig. Um eine optimale Verstellung der Kante 22 des Druckele­mentes zu erreichen, liegt die Oberseite 12 unter einem Winkel α von etwa 40° bis 50° zur Horizontalen (Fig. 1). Wenn die Oberseite 12 in diesem Winkelbereich zur Horizontalen ge­neigt angeordnet ist, läßt sich die Kante 22 des Andruckele­mentes 20 in einem einzigen Verstellvorgang optimal bei den unterschiedlichen Flugkreisdurchmessern in die jeweilige Lage verstellen. Da der Benutzer der Absaughaube somit nur noch einen einzigen Verstellvorgang mittels der Verstellspindel 16 durchführen muß, kann er das Andruckelement 20 ohne Schwie­rigkeiten in die jeweils geforderte Lage bringen.The top 12 is inclined at such an angle to the horizontal that when the suction hood 4 is moved in the direction of the arrow 24, the edge 22 is not only adjusted horizontally but also vertically relative to the cutter head 1. Depending on the flight circle diameter, the edge 22 must not only be adjusted in the horizontal direction, but also in the vertical direction. As a result of the inclined position of the upper side 12, only a single adjustment process is necessary for these two adjustments. In order to achieve an optimal adjustment of the edge 22 of the pressure element, the upper side 12 lies at an angle α of approximately 40 ° to 50 ° to the horizontal (FIG. 1). If the upper side 12 is arranged inclined to the horizontal in this angular range, the edge 22 of the pressure element 20 can be optimally adjusted to the respective position in the different flight circle diameters in a single adjustment process. Since the user of the suction hood thus only has to carry out a single adjustment process by means of the adjustment spindle 16, he can bring the pressure element 20 into the respectively required position without difficulty.

Je nach Flugkreisdurchmesser, d.h. Größe des Messerkopfes 1, fallen unterschiedliche Spanmengen bei der Bearbeitung der Hölzer an. Um diese unterschiedlichen Spänemengen zuverlässig absaugen zu können, ist bei der Absaughaube 4 vorgesehen, ein Späneleit­blech 25 in Abhängigkeit vom Flugkreisdurchmesser zu verstellen. Das Späneleitblech 25 liegt der Wand 19 des Absaugkanals 14 mit Abstand gegenüber und begrenzt mit ihr zusammen die Einführöffnung 26, durch welche die bei der Holzbearbeitung entstehenden Späne in den Absaugkanal 14 gelangen. Das Späneleitblech 25 ist mit einem Scharnier 27 am Träger 5 angelenkt. Wie Fig. 2 zeigt, ist das Späneleitblech 25 an einem Ende 28 entgegengesetzt zum Messerkopf 1 hochgebogen. Dieses hochgebogene Ende 28 bildet ein Leitblech, das mit einer Kurvenbahn 29 versehen ist, der ein Steuerstift 30 zugeordnet ist. Die Kurvenbahn 29 verläuft gekrümmt und ist als längliche Öffnung im Leitblech 28 ausgebildet. Der Steuerstift 30 ist an der Absaughaube 4 vorgesehen und greift in die Kurvenbahn 29 ein. Sie bildet zusammen mit dem Steuerstift 30 eine Zwangsteuerung für das Späneleitblech 25. Wird die Absaughaube 4 mit dem Andruckelement 20 in der beschriebenen Weise mittels der Verstellspindel 16 gegenüber dem Träger 5 verstellt, wird durch diese Zwangsteuerung 29, 30 gleichzeitig auch das Späneleitblech 25 verstellt. Die Kurvenbahn 29 ist so angeordnet, daß das Späneleitblech 25 von der Achse 2 des Messerkopfes 1 weggeschwenkt wird, so­bald das Andruckelement 20 von der Achse 2 entfernt wird. Um­gekehrt wird das Späneleitblech 25 gegen den Messerkopf 1 ge­schwenkt, wenn das Andruckelement 20 näher zur Achse 2 des Messerkopfes 1 eingestellt wird. Auf diese Weise wird die Lage des Späneleitbleches 25 automatisch mit der Lage des Andruckelementes 20 zum Messerkopf 1 gekoppelt, so daß die Einführöffnung 26 in den Absaugkanal 14 stets den optimalen Querschnitt aufweist. Somit wird durch die Verstellung der Absaughaube 4 nicht nur das Andruckelement 20 optimal auf den jeweiligen Flugkreisdurchmesser des Messerkopfes 2 eingestellt, sondern gleichzeitig auch das Späneleitblech 25 in die jewei­lige optimale Lage verstellt. Gesonderte Einstellungen für das Späneleitblech sind darum nicht erforderlich.Depending on the diameter of the flight circle, ie the size of the cutter head 1, different amounts of chips arise when processing the wood. In order to be able to reliably extract these different amounts of chips, the suction hood 4 is provided to adjust a chip guide plate 25 as a function of the flight circle diameter. The chip guide plate 25 lies at a distance from the wall 19 of the suction channel 14 and, together with it, delimits the insertion opening 26 through which the chips produced during woodworking reach the suction channel 14. The chip guide plate 25 is articulated on the carrier 5 with a hinge 27. As shown in FIG. 2, the chip guide plate 25 is bent up at one end 28 opposite to the cutter head 1. This bent end 28 forms one Baffle, which is provided with a curved track 29 with which a control pin 30 is assigned. The cam track 29 is curved and is designed as an elongated opening in the guide plate 28. The control pin 30 is provided on the suction hood 4 and engages in the cam track 29. Together with the control pin 30, it forms a forced control for the chip guide plate 25. If the suction hood 4 with the pressure element 20 is adjusted in the manner described by means of the adjusting spindle 16 relative to the carrier 5, the chip guide plate 25 is simultaneously adjusted by this forced control 29, 30. The cam track 29 is arranged such that the chip guide plate 25 is pivoted away from the axis 2 of the cutter head 1 as soon as the pressure element 20 is removed from the axis 2. Conversely, the chip guide plate 25 is pivoted against the cutter head 1 when the pressure element 20 is set closer to the axis 2 of the cutter head 1. In this way, the position of the chip guide plate 25 is automatically coupled to the position of the pressure element 20 relative to the cutter head 1, so that the insertion opening 26 into the suction channel 14 always has the optimal cross section. Thus, not only is the pressure element 20 optimally adjusted to the respective flight circle diameter of the cutter head 2 by the adjustment of the suction hood 4, but at the same time the chip guide plate 25 is also adjusted to the respective optimal position. Separate settings for the chip guide plate are therefore not necessary.

Die beschriebene Absaughaube erlaubt eine äußerst einfache und dennoch sehr zuverlässige Verstellung zur Anpassung an den jeweiligen Flugkreisdurchmesser des Messerkopfes 1, wo­bei gleichzeitig dafür Sorge getragen wird, daß auch das Späne­leitblech 25 bei dieser Verstellung seine erforderliche optimale Lage einnimmt. Fehleinstellungen sind dadurch ausge­schlossen.The described suction hood allows an extremely simple, yet very reliable adjustment to adapt to the respective flight circle diameter of the cutter head 1, while at the same time care is taken to ensure that the chip guide plate 25 also assumes its required optimal position during this adjustment. Incorrect settings are excluded.
