Description

Die Erfindung betrifft eine Maschine zur Bearbeitung von Werkstücken aus Holz, Kunststoff und dergleichen nach dem Oberbegriff des Anspruches 1.The invention relates to a machine for processing workpieces made of wood, plastic and the like according to the preamble of claim 1.

Mit solchen Maschinen werden beispielsweise Möbelteile in einem Durchgang bearbeitet. Die auf den Möbelteilen aufliegenden, drehbar angetriebenen Transportwalzen transportieren die Möbelteile durch die Maschine. Bei ihrem Durchlauf werden die Möbelteile durch die entsprechenden Bearbeitungswerkzeuge der Maschine bearbeitet. Mit dem oberhalb der Transportbahn vorgesehenen Bearbeitungswerkzeug wird die Oberseite der Möbelteile bearbeitet. Durch die dieses Bearbeitungswerkzeug abdeckende Abdeck- bzw. Absaughaube wird die Reihe der Transportwalzen unterbrochen. Dadurch haben die beiden vor und hinter der Abdeckhaube liegenden Transportwalzen einen verhältnismäßig großen Abstand. Damit die Möbelteile in einem Durchlauf selbsttätig durch die Maschine transportiert werden können, müssen sie mindestens eine Länge haben, die dem Abstand dieser beiden Transportwalzen vor und hinter der Abdeckhaube für die obere Spindel entspricht. Sind die Möbelteile kürzer, dann bleiben sie in Höhe der oberen Spindel stehen, da sie einerseits von der in Transportrichtung vor der Abdeckhaube liegenden Transportwalze freigekommen, von der nachfolgenden Transportwalze hinter der Abdeckhaube aber noch nicht erfaßt worden sind. Erst durch das nächste durch die Maschine laufende Werkstück wird dann dieses Werkstück in den Bereich der hinter der Abdeckhaube liegenden Transportwalze gefördert.With such machines, for example, furniture parts are processed in one pass. The rotatably driven transport rollers resting on the furniture parts transport the furniture parts through the machine. During their passage, the furniture parts are processed by the corresponding processing tools of the machine. The upper side of the furniture parts is processed using the processing tool provided above the transport path. The row of transport rollers is interrupted by the cover or suction hood covering this processing tool. As a result, the two transport rollers lying in front of and behind the cover are at a relatively large distance. So that the furniture parts can be automatically transported through the machine in one pass, they must be at least one length have the distance between these two transport rollers in front of and behind the cover for the upper spindle. If the furniture parts are shorter, then they remain at the height of the upper spindle, since on the one hand they have been released from the transport roller lying in front of the cover in the transport direction, but have not yet been detected by the subsequent transport roller behind the cover. Only through the next workpiece running through the machine is this workpiece then conveyed into the area of the transport roller behind the covering hood.

Der Erfindung liegt die Aufgabe zugrunde, die gattungsgemäße Maschine so auszubilden, daß auch Werkstücke in einem kontinuierlichen Durchlauf durch die Maschine bearbeitet werden können, deren Länge kürzer ist als der Abstand zwischen den vor und hinter der Abdeckhaube der oberen Spindel liegenden Transportwalzen.The invention has for its object to design the generic machine so that workpieces can be processed in a continuous pass through the machine, the length of which is shorter than the distance between the transport rollers lying in front and behind the cover of the upper spindle.

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

Bei der erfindungsgemäßen Maschine befinden sich zwischen den vor und hinter der Abdeckhaube bzw. der darunter befindlichen Spindel liegenden Transportwalzen die im Durchmesser kleineren Zusatzwalzen, so daß die kleinste Werkstücklänge dem Abstand der Achsen dieser Zusatzwalzen entsprechen kann. Aufgrund ihres kleinen Durchmessers können die Zusatzwalzen sehr nahe bis an den Flugkreis des auf der oberen Spindel sitzenden Bearbeitungswerkzeuges reichen. Auf diese Weise ist es in konstruktiv sehr einfacher Weise möglich, auch noch sehr kurze Werkstücke, deren Länge dem Abstand der Achsen dieser Zusatzwalzen entspricht, in einem kontinuierlichen Durchlauf durch die Maschine zu bearbeiten. Die kurzen Werkstücke bleiben darum nicht im Bereich der oberen Spindel stehen, sondern werden durch die Zusatzwalzen zügig weitertransportiert. Vor dem Einlauf in die Abdeckhaube wird das kurze Werkstück von der entsprechenden Zusatzwalze erfaßt und weiter zum Bearbeitungswerkzeug auf der oberen Spindel gefördert. Da in Transportrichtung mit nur geringem Abstand hinter diesem Bearbeitungswerkzeug die andere Zusatzwalze sitzt, wird dieses kurze Werkstück unmittelbar nach der Bearbeitung von ihr erfaßt und der nachfolgenden Transportwalze zugeführt. Mit der erfindungsgemäßen Maschine kann in der Zeiteinheit eine große Zahl von kurzen Werkstücken bearbeitet werden.In the machine according to the invention, the diameter of the additional rollers, which are smaller in diameter, so that the smallest workpiece length can correspond to the distance between the axes of these additional rollers are located between the transport rollers lying in front of and behind the cover or the spindle located underneath. Due to their small diameter, the additional rollers can extend very close to the flight circle of the machining tool sitting on the upper spindle. In this way it is possible in a structurally very simple way, even very much to process short workpieces, the length of which corresponds to the distance between the axes of these additional rollers, in a continuous pass through the machine. The short workpieces therefore do not stop in the area of the upper spindle, but are quickly transported on by the additional rollers. Before entering the cover, the short workpiece is gripped by the corresponding additional roller and further conveyed to the processing tool on the upper spindle. Since the other additional roller sits behind this processing tool with only a small distance in the transport direction, this short workpiece is grasped by it immediately after processing and fed to the subsequent transport roller. With the machine according to the invention, a large number of short workpieces can be processed in the unit of time.

Fig. 2
1 shows a second embodiment of a machine according to the invention.

Die Maschine nach Fig. 1 hat einen Maschinentisch 1, auf dem eine Transportbahn 2 für die zu bearbeitenden Werkstücke 3 vorgesehen ist. Zum Transport der Werkstücke längs der Transportbahn 2 in Transportrichtung 4 dienen drehbar angetriebene Transportwalzen 5, die sich mit Abstand oberhalb der Transportbahn 2 befinden. Die Transportwalzen 5 sind in bekannter Weise an einem (nicht dargestellten) Träger gelagert, der ebenfalls in bekannter Weise an einen Antrieb angeschlossen ist, mit dem die Transportwalzen 5 drehbar angetrieben werden. Sie und/oder der Träger sind höhenverstellbar, so daß ihre Lage auf unterschiedlich dicke Werkstücke 3 eingestellt werden kann. Die Walzen 5 liegen auf dem zu transportierenden Werkstück 3 auf und fördern es in Transportrichtung 4 durch die Maschine.1 has a machine table 1 on which a transport path 2 for the workpieces 3 to be machined is provided. For transporting the workpieces along the transport path 2 in the transport direction 4, rotatably driven transport rollers 5 are used, which are located at a distance above the transport path 2. The transport rollers 5 are mounted in a known manner on a carrier (not shown) which is also connected in a known manner to a drive with which the transport rollers 5 are rotatably driven. You and / or the carrier are adjustable in height so that their position can be adjusted to workpieces 3 of different thicknesses. The rollers 5 rest on the workpiece 3 to be transported and convey it through the machine in the transport direction 4.

Während des Durchlaufes durch die Maschine werden die Werkstücke 3 mit Werkzeugen bearbeitet. Im dargestellten Ausführungsbeispiel hat die Maschine eine untere, horizontale Spindel 6, auf der ein Messerkopf 7 drehfest sitzt. Mit ihm wird beim Durchlauf des Werkstückes 3 dessen Unterseite bearbeitet. Zum Durchtritt des Messerkopfes 7 ist die Transportbahn 2 entsprechend unterbrochen.During the passage through the machine, the workpieces 3 are processed with tools. In the exemplary embodiment shown, the machine has a lower, horizontal spindle 6, on which a cutter head 7 sits in a rotationally fixed manner. It is used to process the underside of the workpiece 3 as it passes through it. For the passage of the knife head 7, the transport path 2 is interrupted accordingly.

In Transportrichtung 4 mit Abstand nach der Spindel 6 ist die Maschine mit einer vertikalen Spindel 8 versehen, auf der drehfest ein Messerkopf 9 sitzt. Er ist von einer Schutz- bzw. Absaughaube 10 umgeben. Die drehbar angetriebene Spindel 8 mit dem Messerkopf 9 kann in Transportrichtung 4 des Werkstückes rechts oder links des zu bearbeitenden Werkstückes angeordnet sein. Je nach Lage der Spindel 8 wird somit die rechte oder linke Längsseite des Werkstückes 3 beim Transport durch die Maschine durch den Messerkopf 9 bearbeitet.In the direction of transport 4 at a distance after the spindle 6, the machine is provided with a vertical spindle 8, on which a cutter head 9 is fixed in rotation. It is surrounded by a protective or exhaust hood 10. The rotatably driven spindle 8 with the cutter head 9 can be arranged on the right or left of the workpiece to be machined in the direction of transport 4 of the workpiece. Depending on the position of the spindle 8, the right or left Machined the long side of the workpiece 3 during transport through the machine by the cutter head 9.

In Transportrichtung 4 mit Abstand hinter der Spindel 8 ist die Maschine mit einer weiteren vertikalen, drehbar angetriebenen Spindel 11 versehen, auf der drehfest ein Messerkopf 12 sitzt. Er ist wiederum von einer Abdeck- bzw. Absaughaube 13 umgeben. In der Zeichnung ist diese Spindel 11 zur besseren Darstellung in einer um 180° nach unten geklappten Stellung dargestellt.In the transport direction 4 at a distance behind the spindle 8, the machine is provided with a further vertical, rotatably driven spindle 11, on which a cutter head 12 is seated in a rotationally fixed manner. It is in turn surrounded by a cover or suction hood 13. In the drawing, this spindle 11 is shown in a position folded down by 180 ° for better illustration.

Die beiden Spindeln 8 und 11 befinden sich auf einander gegenüberliegenden Seiten des Werkstückes 3, in dessen Transportrichtung 4 gesehen. Dadurch können die beiden Längsseiten des Werkstückes 3 bearbeitet werden. Es ist auch möglich, die Spindel 11 mit dem Messerkopf 12 zusammen mit der Spindel 8 und dem Messerkopf 9 auf der gleichen Seite anzuordnen, so daß das Werkstück 3 bei seinem Transport durch die Maschine durch beide Messerköpfe 9 und 11 an der rechten bzw. linken Längsseite bearbeitet werden kann.The two spindles 8 and 11 are located on opposite sides of the workpiece 3, seen in the transport direction 4. As a result, the two long sides of the workpiece 3 can be machined. It is also possible to arrange the spindle 11 with the cutter head 12 together with the spindle 8 and the cutter head 9 on the same side, so that the workpiece 3 is transported on the right and left when it is transported through the machine by both cutter heads 9 and 11 Long side can be edited.

Im Bereich der vertikalen Spindel 11 ist die Reihe der Transportwalzen 5 nicht unterbrochen, da sich diese Spindel 11 im Bereich neben der Transportwalzenreihe befindet.The row of transport rollers 5 is not interrupted in the area of the vertical spindle 11, since this spindle 11 is located in the area next to the row of transport rollers.

In Transportrichtung 4 mit Abstand hinter der Spindel 11 ist die Maschine mit einer horizontalen oberen Spindel 14 versehen, auf der drehfest ein Messerkopf 15 sitzt, mit dem die Oberseite des Werkstückes 3 bei seinem Durchgang bearbeitet wird. Der Messerkopf 15 liegt unter einer Abdeck- bzw. Absaughaube 16, die ihn nach oben und seitlich abdeckt. Da die Abdeckhaube 16, in Transportrichtung 4 gesehen, über die Reihe der Transportwalzen 5 ragt, können im Bereich dieser Abdeckhaube 16 die Transportwalzen 5 nicht vorgesehen sein. Der Abstand zwischen den beiden in Transportrichtung 4 vor und hinter der Abdeckhaube 16 liegenden Transportwalzen 5 bestimmt bei den herkömmlichen Maschinen die kürzeste Länge, welche die Werkstücke 3 haben können. Sind die Werkstücke kürzer als dieser Abstand, dann können sie nicht an der Spindel 14 vorbei transportiert werden, da das Werkstück, wenn es von der in Transportrichtung 4 vor der Abdeckhaube 16 liegenden Transportwalze 5 freikommt, noch nicht durch die in Transportrichtung 4 hinter der Abdeckhaube 16 liegenden Transportwalze erfaßt worden ist. Ein Weitertransport dieser Werkstücke ist dann nur möglich, indem sie durch ein nachfolgendes Werkstück weitergeschoben werden. Dann gelangen diese Werkstücke wieder unter die in Transportrichtung 4 hinter der Abdeckhaube 16 liegende Transportwalze 5. Kommt kein nachfolgendes Werkstück, dann bilden sich auf dem unter der Spindel liegenden Werkstück 3 unerwünschte Markierungen, die durch das rotierende Werkzeug 15 auf dem stillstehenden Werkstück 3 erzeugt werden. Es stellt dann Ausschuß dar und kann nicht mehr weiterverwendet werden.In the direction of transport 4 at a distance behind the spindle 11, the machine is provided with a horizontal upper spindle 14, on which a cutter head 15 sits in a rotationally fixed manner, with which the upper side of the workpiece 3 is machined during its passage. The cutter head 15 is located under a cover or suction hood 16, which covers it upwards and laterally. Since the cover 16, in the transport direction 4 seen, protrudes beyond the row of transport rollers 5, the transport rollers 5 cannot be provided in the area of this cover 16. The distance between the two transport rollers 5 lying in front of and behind the cover 16 in the transport direction 4 determines the shortest length that the workpieces 3 can have in the conventional machines. If the workpieces are shorter than this distance, they cannot be transported past the spindle 14, since the workpiece, when it comes free from the transport roller 5 lying in front of the cover 16 in the transport direction 4, does not pass through the behind the cover in the transport direction 4 16 lying transport roller has been detected. A further transport of these workpieces is then only possible by pushing them through a subsequent workpiece. Then these workpieces again come under the transport roller 5 lying behind in the transport direction 4 behind the cover 16. If there is no subsequent workpiece, undesired markings are formed on the workpiece 3 under the spindle, which are generated by the rotating tool 15 on the stationary workpiece 3 . It then constitutes a committee and can no longer be used.

Bei der beschriebenen und dargestellten Maschine können die Werkstücke 3 wesentlich kürzer sein als bei den bekannten Maschinen. Dies ist darauf zurückzuführen, daß zwischen den beiden vor und hinter der Abdeckhaube 16 liegenden Transportwalzen 5 im Durchmesser kleinere Zusatzwalzen 17 und 18 vorgesehen sind, deren Achsabstand 19 wesentlich kleiner ist als der Achsabstand zwischen den beiden vor und hinter der Abdeckhaube liegenden Transportwalzen 5. In der Fig. 1 ist dargestellt, daß das kurze Werkstück 3 von beiden Zusatzwalzen 17 und 18 erfaßt und damit einwandfrei transportiert wird. Dadurch lassen sich im Vergleich zu herkömmlichen Maschinen Werkstücke bearbeiten, deren Länge nahezu um die Hälfte kleiner ist als bei Einsatz der bekannten Maschinen.In the machine described and shown, the workpieces 3 can be significantly shorter than in the known machines. This can be attributed to the fact that between the two transport rollers 5 lying in front of and behind the cover 16, smaller additional rollers 17 and 18 are provided, the center distance 19 of which is considerably smaller than the center distance between the two transport rollers lying in front of and behind the cover 5. In 1 is shown that the short workpiece 3 by both additional rollers 17 and 18th recorded and thus transported properly. Compared to conventional machines, this enables workpieces to be machined whose length is almost half that of the known machines.

Die Zusatzwalzen 17, 18 sind ebenfalls angetrieben und so auf die Drehzahl der Transportwalzen 5 abgestimmt, daß das Werkstück 3 im Bereich der Abdeckhaube 16 gleichmäßig transportiert wird. Die Zusatzwalzen 17, 18 und die Transportwalzen 5 haben die gleiche Umfangsgeschwindigkeit. Der Radius der Zusatzwalzen 17, 18 ist wesentlich kleiner als der Radius der Transportwalzen 5. Senkrecht zur Transportrichtung 4 gesehen ragen die Zusatzwalzen 17, 18 teilweise in die Abdeckhaube 16.The additional rollers 17, 18 are also driven and matched to the speed of the transport rollers 5 so that the workpiece 3 is transported evenly in the area of the cover 16. The additional rollers 17, 18 and the transport rollers 5 have the same peripheral speed. The radius of the additional rollers 17, 18 is substantially smaller than the radius of the transport rollers 5. Seen perpendicular to the transport direction 4, the additional rollers 17, 18 partially protrude into the cover 16.

Vorteilhaft sind die Zusatzwalzen 17, 18 an der Abdeckhaube 16 gelagert. Dies hat den Vorteil, daß die Zusatzwalzen 17, 18 zusammen mit der Abdeckhaube abgenommen werden können, wenn beispielsweise der Messerkopf 15 auf der Spindel 14 ausgetauscht werden soll. Bei der dargestellten Maschine ist der Abstand zwischen den beiden vor und hinter der Absaughaube 16 liegenden Transportwalzen 5 so gewählt, daß anstelle des Messerkopfes 15 und der an dessen Flugkreisdurchmesser angepaßten Absaughaube 16 ein im Flugkreisdurchmesser größerer Messerkopf mit einer in Transportrichtung entsprechend längeren Absaughaube eingesetzt werden kann. Dann ergibt sich eine herkömmliche Maschine, welche die Zusatzwalzen nicht aufweist. Somit ist es möglich, eine solche bekannte Maschine durch Austausch gegen den im Flugkreisdurchmesser kleineren Messerkopf 15 mit der in Transportrichtung entsprechend kurzen Absaughaube 16 und den Zusatzwalzen 17, 18 umzurüsten. An der Abdeckhaube 16 sind im Bereich der beiden senkrecht zur Transportrichtung 4 liegenden Außenseiten 20 und 21 Getriebegehäuse 22 und 23 angelenkt, in denen zur Synchronisation der Zusatzwalzen 17, 18 mit den Transportwalzen 5 jeweils ein Übersetzungsgetriebe für Wellen 24 und 25 untergebracht ist, auf denen die Zusatzwalzen 17, 18 drehfest sitzen. Diese Wellen 24, 25 erstrecken sich senkrecht zur Transportrichtung 4 und horizontal. Die Getriebegehäuse 22, 23 sind um zueinander parallele Achsen 26 und 27 schwenkbar an der Abdeckhaube 16 gelagert. Die Schwenkachsen 26, 27 liegen parallel zu den Wellen 24, 25, die senkrecht aus den Getriebegehäusen 22, 23 ragen.The additional rollers 17, 18 are advantageously mounted on the cover 16. This has the advantage that the additional rollers 17, 18 can be removed together with the cover if, for example, the cutter head 15 on the spindle 14 is to be replaced. In the illustrated machine, the distance between the two transport rollers 5 located in front of and behind the suction hood 16 is selected such that, instead of the cutter head 15 and the suction hood 16 adapted to its flight circle diameter, a cutter head which is larger in the flight circle diameter and has a correspondingly longer suction hood in the transport direction can be used . The result is a conventional machine that does not have the additional rollers. It is thus possible to convert such a known machine by exchanging it for the cutter head 15, which is smaller in the flight circle diameter, with the suction hood 16, which is correspondingly short in the transport direction, and the additional rollers 17, 18. The cover 16 is in the region of the two perpendicular to the direction of transport 4 lying outer sides 20 and 21 gear housing 22 and 23 are articulated, in which for the synchronization of the additional rollers 17, 18 with the transport rollers 5 a transmission gear for shafts 24 and 25 is accommodated, on which the additional rollers 17, 18 are non-rotatably seated. These waves 24, 25 extend perpendicular to the transport direction 4 and horizontally. The gearboxes 22, 23 are pivotally mounted on the cover 16 about axes 26 and 27 which are parallel to one another. The pivot axes 26, 27 are parallel to the shafts 24, 25, which protrude perpendicularly from the gear housings 22, 23.

Auf der Abdeckhaube 16 ist ein Halter 28 befestigt, an dem Stelleinrichtungen 29 und 30 zur Verstellung der Getriebegehäuse 22, 23 und damit der Zusatzwalzen 17, 18 vorgesehen sind. Mit diesen Stelleinrichtungen können die Zusatzwalzen 17, 18 zur Feinanpassung an Werkstücktoleranzen in der Höhe eingestellt werden.A holder 28 is fastened on the cover 16, on which actuating devices 29 and 30 for adjusting the gear housing 22, 23 and thus the additional rollers 17, 18 are provided. With these adjusting devices, the additional rollers 17, 18 can be adjusted in height for fine adjustment to workpiece tolerances.

Die Stelleinrichtung 29 hat eine Gewindespindel 31, die an einem Ende gelenkig mit dem Getriebegehäuse 22 verbunden ist. Die Gewindespindel 31 ragt durch ein aufwärts abgewinkeltes Ende 32 des Halters 28 sowie durch eine mit einem Sterngriff 33 versehene Mutter 34, die in bekannter Weise am Halterende 32 drehbar gelagert ist. Durch Drehen der Mutter 34 wird die Gewindespindel 31 relativ zum Halterende 32 verschoben, wodurch das Getriebegehäuse 22 und mit ihm die Zusatzwalze 17 in der Höhe relativ zur Abdeckhaube 16 verstellt wird.The actuating device 29 has a threaded spindle 31 which is connected at one end to the gear housing 22 in an articulated manner. The threaded spindle 31 projects through an upwardly angled end 32 of the holder 28 and through a nut 34 provided with a star grip 33, which is rotatably mounted on the holder end 32 in a known manner. By turning the nut 34, the threaded spindle 31 is displaced relative to the holder end 32, as a result of which the height of the gear housing 22 and with it the additional roller 17 is adjusted relative to the cover 16.

Die Stelleinrichtung 30 hat einen Stellzylinder 35, vorzugsweise einen Pneumatikzylinder, dessen Kolbenstange 36 über ein Anlenkstück 37 am Getriebegehäuse 23 angelenkt ist. Der Stellzylinder 35 selbst ist an dem in Transportrichtung 4 nach hinten über die Abdeckhaube 16 ragenden Ende des Halters 28 befestigt. Durch Aus- bzw. Einfahren der Kolbenstange 36 kann das Getriebegehäuse 23 und damit die Zusatzwalze 18 um die Achse 27 verschwenkt werden.The actuating device 30 has an actuating cylinder 35, preferably a pneumatic cylinder, the piston rod 36 of which is articulated on the gear housing 23 via a link 37. The actuating cylinder 35 itself is on the in Transport direction 4 attached to the rear over the cover 16 projecting end of the holder 28. By extending or retracting the piston rod 36, the gear housing 23 and thus the additional roller 18 can be pivoted about the axis 27.

Mit beiden Stelleinrichtungen 29, 30 werden die Zusatzwalzen 17, 18 auch mit der nötigen Druckkraft auf das Werkstück 3 gedrückt.With both actuators 29, 30, the additional rollers 17, 18 are pressed onto the workpiece 3 with the necessary compressive force.

Die Spindel 14 mit dem Messerkopf 15 und der Abdeckhaube 16 ist in bekannter Weise an einem in der Zeichnung nur angedeuteten Träger 38 angeordnet, der im Bereich oberhalb der Abdeckhaube verläuft. Im Träger 38 ist in bekannter Weise eine Verstelleinrichtung untergebracht, mit der die Spindel 14 und die Abdeckhaube 16 in der Höhe verstellt werden können. Dadurch läßt sich auch die Spindel 14 an unterschiedlich dicke Werkstücke 3 einfach anpassen. Da die Zusatzwalzen 17, 18 mit der Abdeckhaube 16 in der beschriebenen Weise verbunden sind, werden sie bei der Höhenverstellung der Spindel 14 in gleicher Weise in der Höhe verstellt. Außerdem können die Zusatzwalzen 17, 18 mittels der Stelleinrichtungen 29, 30 relativ zur Spindel 14 zur Feinanpassung an Werkstücktoleranzen verstellt werden.The spindle 14 with the cutter head 15 and the cover 16 is arranged in a known manner on a support 38, only indicated in the drawing, which extends in the region above the cover. In the carrier 38, an adjusting device is accommodated in a known manner, with which the spindle 14 and the cover 16 can be adjusted in height. As a result, the spindle 14 can also be easily adapted to workpieces 3 of different thicknesses. Since the additional rollers 17, 18 are connected to the cover 16 in the manner described, they are adjusted in height in the same manner when the spindle 14 is adjusted. In addition, the additional rollers 17, 18 can be adjusted by means of the adjusting devices 29, 30 relative to the spindle 14 for fine adjustment to workpiece tolerances.

Die Zusatzwalzen 17, 18 sind ebenso wie die Transportwalzen 5 pendelnd gelagert, so daß sie sich Unebenheiten auf der Oberseite des Werkstückes 3 anpassen können. Eine solche Pendellagerung der Transportwalzen 5 ist bei derartigen Maschinen bekannt und wird darum nicht näher beschrieben.The additional rollers 17, 18, like the transport rollers 5, are pivoted so that they can adapt to unevenness on the top of the workpiece 3. Such a pendulum mounting of the transport rollers 5 is known in such machines and is therefore not described in detail.

Mit den Zusatzwalzen 17, 18 lassen sich somit auch sehr kurze Werkstücke 3 einwandfrei durch die Maschine transportieren.With the additional rollers 17, 18, even very short workpieces 3 can thus be transported through the machine without any problems.

Der Abstand 19 zwischen den Achsen der Zusatzwalzen 17, 18 ist größer als der Abstand zwischen den Zusatzwalzen und der jeweils benachbarten Transportwalze 5. Dadurch ist auf jeden Fall sichergestellt, daß vor und hinter der Spindel 14 die Werkstücke 3 zuverlässig weitertransportiert werden können.The distance 19 between the axes of the additional rollers 17, 18 is greater than the distance between the additional rollers and the adjacent transport roller 5. This ensures in any case that the workpieces 3 can be reliably transported in front of and behind the spindle 14.

Wie die Fig. 1 zeigt, befindet sich in Transportrichtung 4 hinter der Zusatzwalze 17 eine weitere untere, horizontal liegende Spindel 39, auf der ein Messerkopf 40 drehfest sitzt. Mit ihm kann das Werkstück 3 an seiner Unterseite erneut bearbeitet werden. Die Transportbahn 2 ist für den Durchtritt des Messerkopfes 40 in bekannter Weise unterbrochen.As shown in FIG. 1, there is a further lower, horizontally lying spindle 39 in the transport direction 4 behind the additional roller 17, on which a cutter head 40 is seated in a rotationally fixed manner. With it, the workpiece 3 can be reworked on its underside. The transport path 2 is interrupted for the passage of the cutter head 40 in a known manner.

Mit der Maschine können vorteilhaft Möbelteile, aber auch Fensterteile aus Holz, Kunststoff und ähnlichen Werkstoffen bearbeitet werden. Die Werkstücke 3 können selbstverständlich auch lang sein.Furniture, but also window parts made of wood, plastic and similar materials can be processed advantageously with the machine. The workpieces 3 can of course also be long.

Die in Einlaufrichtung vor der Abdeckhaube 16 liegende Zusatzwalze 18 ist vorteilhaft eine gezahnte, aus Stahl oder Guß oder ähnlichem Material bestehende Walze. Sie gewährleistet einen formschlüssigen Eingriff in das Werkstück 3, das dadurch zuverlässig dem Messerkopf 15 zugeführt wird. Die andere, in Transportrichtung 4 nach dem Messerkopf 15 liegende Zusatzwalze 17 hat eine elastische, nachgiebige Mantelfläche, um eine Beschädigung der bearbeiteten Werkstückoberseite zu vermeiden. Mit dieser Zusatzwalze 17 wird das Werkstück 3 kraftschlüssig weitertransportiert.The additional roller 18 lying in front of the cover 16 in the inlet direction is advantageously a toothed roller made of steel or cast iron or similar material. It ensures a positive engagement in the workpiece 3, which is thereby reliably fed to the cutter head 15. The other additional roller 17 lying in the transport direction 4 after the cutter head 15 has an elastic, resilient outer surface in order to avoid damage to the machined upper side of the workpiece. With this additional roller 17, the workpiece 3 is transported non-positively.

Auf den verschiedenen Spindeln können außer Messerköpfen auch andere geeignete Bearbeitungswerkzeuge, wie Fräser, eingesetzt werden.In addition to cutter heads, other suitable processing tools such as milling cutters can also be used on the various spindles.

Bei der Ausführungsform gemäß Fig. 2 sind die Zusatzwalzen 17a, 18a nicht an der Abdeckhaube 16a, sondern an jeweils einem Träger 41 und 42 über die jeweilige Stelleinrichtung 29a, 30a angeordnet. Die Zusatzwalzen 17a, 18a sind in bezug auf die Abdeckhaube 16a gleich angeordnet wie beim Ausführungsbeispiel nach Fig. 1. Somit können auch mit dieser Maschine auch sehr kurze Werkstücke 3 einwandfrei transportiert werden.In the embodiment according to FIG. 2, the additional rollers 17a, 18a are not arranged on the cover 16a, but rather on a carrier 41 and 42 each via the respective adjusting device 29a, 30a. The additional rollers 17a, 18a are arranged in relation to the cover 16a in the same way as in the exemplary embodiment according to FIG. 1. Thus, very short workpieces 3 can also be transported perfectly with this machine.

Mit den beiden Stelleinrichtungen 29a, 30a werden die Zusatzwalzen 17a, 18a mit der nötigen Kraft auf das Werkstück 3 gedrückt. Diese Kraft kann hydraulisch, pneumatisch oder mechanisch, bsp. durch wenigstens eine Druckfeder erzeugt werden. Wie beim vorigen Ausführungsbeispiel können die Zusatzwalzen 17a, 18a mit den Stelleinrichtungen 29a, 30a zur Feinanpassung an Werkstücktoleranzen in der Höhe eingestellt werden.With the two adjusting devices 29a, 30a, the additional rollers 17a, 18a are pressed onto the workpiece 3 with the necessary force. This force can be hydraulic, pneumatic or mechanical, e.g. are generated by at least one compression spring. As in the previous exemplary embodiment, the additional rollers 17a, 18a can be adjusted in height with the adjusting devices 29a, 30a for fine adjustment to workpiece tolerances.

Die Träger 41, 42 sind an den ansich bekannten (nicht dargestellten) Vorschubbalken gelagert, der entsprechend der vorigen Ausführungsform in bekannter Weise an einen Antrieb angeschlossen ist, mit dem die Transportwalzen für drehbar angetrieben werden. Die Drehzahl der Zusatzwalzen 17a, 18a, kann mittels der in den Getriebegehäusen 22a, 23a untergebrachten Übersetzungsgetrieben an die Drehzahl der Transportwalzen so angepaßt werden, daß sämtliche Walzen die gleiche Umfangsgeschwindigkeit haben.The carriers 41, 42 are mounted on the feed bar (not shown) which is known per se and, in accordance with the previous embodiment, is connected in a known manner to a drive with which the transport rollers are driven for rotation. The speed of the additional rollers 17a, 18a can be adapted to the speed of the transport rollers by means of the transmission gears accommodated in the gearboxes 22a, 23a so that all rollers have the same peripheral speed.

Die Abdeckhaube 16a hat Aussparungen, durch welche die Zusatzwalzen 17a, 18a ragen. Soll der in der Abdeckhaube 16a befindliche Messerkopf 15a gegen einen Messerkopf mit einem größeren Flugkreisdurchmesser ausgetauscht werden, dann ist ein Wechsel der Abdeckhaube 16a nicht erforderlich. Die Zusatzwalzen 17a, 18a werden hochgetaktet oder abgenommen. Dann ergibt sich eine herkömmliche Maschine, bei der die Zusatzwalzen 17a, 18a nicht wirksam bzw. nicht vorhanden sind.The cover 16a has cutouts through which the additional rollers 17a, 18a protrude. If the cutter head 15a located in the cover 16a is to be exchanged for a cutter head with a larger flight circle diameter, then a replacement of the cover 16a is not necessary. The additional rollers 17a, 18a are clocked up or removed. A conventional machine then results, in which the additional rollers 17a, 18a are not effective or are not present.

Das Ausführungsbeispiel gemäß Fig. 2 ist im übrigen gleich ausgebildet wie die Ausführungsform nach Fig. 1.The embodiment according to FIG. 2 is otherwise the same as the embodiment according to FIG. 1.
