Abstract

The wood-working machine has spindles which carry wood-working tools. The wood to be worked is transported through the machine by a feed unit. The machine has supports (32, 35) which are adjustable transversely to the transport direction (31) of the wood and carry two wood-working tools (1, 2, 3, 4). They can be alternatively shifted with the respective support into a working and a rest position. As long as one wood-working tool is in the working position, work necessary at the other wood-working tool located in the rest position can be carried out without the wood-working machine having to be stopped or the passage of the wood through the machine having to be interrupted. …<IMAGE>…

Description

Die Erfindung betrifft eine Holzbearbeitungsmaschine, insbe­sondere eine Kehlmaschine, nach dem Oberbegriff des An­spruches 1.The invention relates to a woodworking machine, in particular a moulder, according to the preamble of claim 1.

Es sind Kehlmaschinen bekannt, die in Transportrichtung der Hölzer hintereinander eine rechte, eine linke, eine obere und eine untere Spindel aufweisen, die jeweils Messerköpfe tragen. Die Hölzer werden dadurch beim Durchgang durch die Kehlmaschine nacheinander an der rechten, an der linken, an der oberen und an der unteren Seite bearbeitet. Müssen bei­spielweise die Messer eines dieser Messerköpfe ausgewechselt oder gejointet werden, ist es notwendig, die Maschine während dieser Zeit stillzusetzen. Die Ausfallzeiten sind dadurch verhältnismäßig hoch. Auch wenn ein ganzer Messerkopf ausge­wechselt werden soll, muß die bekannte Kehlmaschine stillge­setzt werden.Molding machines are known which have one right, one left, one upper and one lower spindle one behind the other in the direction of transport of the timbers, each of which carries cutter heads. As a result, the woods are processed one after the other on the right, on the left, on the upper and on the lower side. If, for example, the knives of one of these cutter heads have to be replaced or jointed, it is necessary to stop the machine during this time. This is downtime relatively high. Even if an entire cutter head is to be replaced, the known moulder must be stopped.

Der Erfindung liegt die Aufgabe zugrunde, die gattungsgemäße Holzbearbeitungsmaschine so auszubilden, daß die Stillstands­zeiten bei Arbeiten an der Maschine kleiner gehalten werden können.The invention has for its object to design the generic woodworking machine so that the downtimes when working on the machine can be kept smaller.

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

Mit dem quer zur Transportrichtung der Hölzer verstellbaren Träger lassen sich die beiden auf ihm gelagerten Bearbei­tungswerkzeuge in eine Arbeits- und in eine Ruhestellung ver­stellen. Solange sich das eine Bearbeitungswerkzeug in der Arbeitsstellung befindet, können am anderen, in der Ruhestel­lung befindlichen Arbeitswerkzeug notwendige Arbeiten vorge­nommen werden, ohne daß die Holzbearbeitungsmaschine stillge­setzt oder der Durchlauf der Hölzer durch die Maschine unter­brochen werden muß. An dem in Ruhestellung befindlichen Be­arbeitungswerkzeug können daher in Ruhe beispielsweise die Messer ausgetauscht oder gejointet werden. Auch ein Austausch des gesamten Messerkopfes ist ohne weiteres möglich. Während dieser Arbeiten muß die Bearbeitung der Hölzer nicht unter­brochen werden. Die Stillstandszeiten der erfindungsgemäßen Holzbearbeitungsmaschine sind dann nur noch wegen der Verstel­lung des Trägers notwendig. Dadurch können mit der erfindungsge­mäßen Holzbearbeitungsmaschine sehr hohe Leistungen erzielt werden.With the support, which can be adjusted transversely to the direction of transport of the wood, the two processing tools mounted on it can be adjusted to a working and a rest position. As long as the one working tool is in the working position, necessary work can be carried out on the other working tool in the rest position without the woodworking machine having to be stopped or the passage of the wood through the machine having to be interrupted. On the processing tool which is in the rest position, the knives can, for example, be exchanged or jointed at rest. It is also easy to replace the entire cutter head. The processing of the wood does not have to be interrupted during this work. The downtimes of the woodworking machine according to the invention are then only necessary because of the adjustment of the carrier. As a result, very high performances can be achieved with the woodworking machine according to the invention.

Weitere Merkmale ergeben sich aus den weiteren Ansprüchen, der Beschreibung und den Zeichnungen.Further features result from the further claims, the description and the drawings.

Die Holzbearbeitungsmaschine ist eine Kehlmaschine, in der Hölzer bearbeitet werden. Zur Bearbeitung der Hölzer weist die Kehlmaschine Messerköpfe 1 bis 8 auf, die jeweils auf Spindeln 9 bis 16 sitzen. Die Spindeln 9 bis 12 stehen vertikal, während die Spindeln 13 bis 16 horizontal angeordnet sind. In Fig. 1 sind die horizontalen Spindeln 13 bis 16 lediglich durch strichpunktierte Linien angedeutet.The woodworking machine is a moulder in which wood is processed. For processing the woods, the moulder has cutter heads 1 to 8, which are each seated on spindles 9 to 16. The spindles 9 to 12 are vertical, while the spindles 13 to 16 are arranged horizontally. In Fig. 1, the horizontal spindles 13 to 16 are only indicated by dash-dotted lines.

Die Kehlmaschine hat einen Ständer 17, auf dem eine Tischplatte 18 angeordnet ist, auf der die Hölzer durch die Kehlmaschine transportiert werden. An einer Längsseite ist die Tischplatte mit Anschlaglinealen 19 bis 21 versehen, an denen die Hölzer bei ihrem Durchgang durch die Kehlmaschine anliegen. Zum Transport der Hölzer dienen Vorschubrollen 22, die an einem Träger 23 einer Vorschubeinheit 24 gelagert sind. Zum Antrieb der Vorschubrollen 22 dient ein Antriebsmotor 25, der an der Vorschubeinheit 24 vorgesehen ist. Zur Anpassung an unterschiedlich dicke Hölzer kann der Träger 23 in der Höhe verstellt werden. Der Träger 23 ist zweiteilig ausgebildet und weist einen im Bereich der verti­kalen Spindeln 9 bis 12 liegenden Trägerteil 26 sowie einen in Durchlaufrichtung der Hölzer hinter den horizontalen Spindeln 13 bis 16 liegenden Trägerteil 27 (Fig. 1) auf. Beide Trägerteile 26, 27 sind miteinander gekuppelt, so daß sie die Bewegungen des Trägers 23 in gleichem Maße mitmachen. Der Trägerteil 27 kann in Horizontalrichtung 28 gegenüber dem Trägerteil 26 verstellt werden.The moulder has a stand 17, on which a table top 18 is arranged, on which the wood is transported through the moulder. On one long side, the table top is provided with stop rulers 19 to 21, against which the woods rest as they pass through the moulder. Feed rollers 22, which are mounted on a carrier 23 of a feed unit 24, are used to transport the woods. A drive motor 25, which is provided on the feed unit 24, is used to drive the feed rollers 22. The height of the support 23 can be adjusted to match different thicknesses of wood. The carrier 23 is formed in two parts and has a support part 26 lying in the area of the vertical spindles 9 to 12 and a support part 27 (FIG. 1) lying behind the horizontal spindles 13 to 16 in the direction of travel of the woods. Both carrier parts 26, 27 are coupled to one another so that they participate in the movements of the carrier 23 to the same extent. The carrier part 27 can be adjusted in the horizontal direction 28 relative to the carrier part 26.

Im Bereich unterhalb der beiden in Durchführrichtung durch die Kehlmaschine ersten Vorschubrollen 22 befindet sich eine horizontal liegende Abrichtspindel 29 mit einem Abrichtwerkzeug 30, mit dem die Hölzer beim Einlauf in die Kehlmaschine an der Unterseite abgerichtet werden. Für den Durchtritt des Abricht­werkzeuges 30 ist die Tischplatte 18 unterbrochen. In Durchlauf­richtung nach dem Abrichtwerkzeug 30 ist die Kehlmaschine mit einem horizontal, d.h. quer zur Transportrichtung 31 der Hölzer verstellbaren Schieber 32 versehen, der die beiden vertikalen Spindeln 9 und 10 mit den Messerköpfen 1 und 2 trägt. Der Schieber 32 trägt darüberhinaus auch die für den Antrieb der Spindeln 9, 10 notwendigen Antriebsorgane sowie Andruckelemente für die durchlaufenden Hölzer. Der Schieber 32 kann zwischen zwei End­stellungen verschoben werden, so daß wahlweise die Spindel 9 oder die Spindel 10 zum Bearbeiten der Hölzer herangezogen werden kann. In der in Fig. 1 dargestellten einen Endstellung bearbeitet der Messerkopf 1 die in Durchlaufrichtung rechte Seite der Hölzer. Der Messerkopf 1 ragt in diesem Falle zwischen den beiden An­schlaglinealen 19 und 20 hindurch. Die andere Spindel 10 mit dem Messerkopf 2 befindet sich hierbei in einer Ruhe- bzw. Wechselstellung außerhalb der Durchlaufbahn bzw. der Tisch­platte 18. Der Messerkopf 2 kann in dieser Ruhestellung bei­spielsweise ausgewechselt oder mit neuen Messern bestückt werden, ohne daß die Bearbeitung der Hölzer unterbrochen werden muß.In the area below the two feed rollers 22, which are the first in the direction of passage through the moulder, there is a horizontal dressing spindle 29 with a dressing tool 30 with which the woods are dressed on the underside when they enter the moulder. The table top 18 is interrupted for the passage of the dressing tool 30. In the direction of travel after the dressing tool 30, the moulder is provided with a slide 32 which can be adjusted horizontally, ie transversely to the transport direction 31 of the timbers, and which carries the two vertical spindles 9 and 10 with the cutter heads 1 and 2. The slide 32 also carries the necessary drive elements for driving the spindles 9, 10 and pressure elements for the passing woods. The slide 32 can be moved between two end positions, so that either the spindle 9 or the spindle 10 can be used to process the woods. In the one end position shown in FIG. 1, the cutter head 1 processes the right side of the timbers in the direction of passage. In this case, the cutter head 1 projects between the two stop rulers 19 and 20. The other spindle 10 with the cutter head 2 is in a rest or change position outside of the continuous path or the table top 18. The cutter head 2 can be replaced in this rest position, for example, or equipped with new knives without having to interrupt the processing of the wood.

Dem Messerkopf 2 ist ein Andruckschuh 33 zugeordnet, der in Durchlaufrichtung 31 vor dem Messerkopf angeordnet ist. Der Andruckschuh 33 hat eine schräg nach hinten in Transport­richtung 31 verlaufende vertikale Andruckfläche 34. Wird der Schieber 32 in seine andere Endlage verstellt, dann be­findet sich der Messerkopf 2 in Arbeitslage, während sich der Messerkopf 1 im Bereich außerhalb des Transportweges und der Tischplatte 18 befindet. Dann kann der Messerkopf 1 beispielweise ausgewechselt werden. Der Messerkopf 2 bear­beitet dann die in Transportrichtung 31 linke Seite der Hölzer. Der Andrückschuh 33 stellt sicher, daß die Hölzer einwandfrei gegen die Anschlaglineale 19 und 20 gedrückt werden, wenn sie am Messerkopf 2 vorbeilaufen.A pressure shoe 33 is assigned to the cutter head 2 and is arranged in the direction of passage 31 in front of the cutter head. The pressure shoe 33 has a vertical pressure surface 34 which runs obliquely to the rear in the transport direction 31. If the slide 32 is adjusted to its other end position, then the knife head 2 is in the working position, while the knife head 1 is in the region outside the transport path and the table top 18 . Then the cutter head 1 can be replaced, for example. The cutter head 2 then processes the left side of the timbers in the transport direction 31. The pressure shoe 33 ensures that the woods are properly pressed against the stop rulers 19 and 20 when they pass the cutter head 2.

Der Schieber 32 ist auf seiner einem benachbarten Schieber 35 zugewandten Seite mit einem Anschlaglineal 36 versehen, längs dem die Hölzer bei ihrem Durchlauf durch die Kehl­maschine geführt werden können. Das Anschlaglineal 36 hat eine Führungsfläche 37, die parallel zur Transportrichtung 31 liegt und an einem im Grundriß etwa dreieckigen Träger 38 vorgesehen ist. Er kann um eine (nicht dargestellte) horizon­tale, senkrecht zur Transportrichtung 31 liegende Achse aus der in Fig. 1 dargestellten Lage in eine Ruhestellung wegge­klappt werden. Hierzu ist am Schieber 32 ein (nicht dargestellter Antrieb vorgesehen, beispielsweise in Form eines Pneumatik­zylinders. Das Anschlaglineal 36 ist in Höhe des Messerkopfes 2 vorgesehen, so daß es beim Arbeiten des Messerkopfes 1 nicht wirksam wird.The slide 32 is provided on its side facing an adjacent slide 35 with a stop ruler 36, along which the woods can be guided as they pass through the molding machine. The stop ruler 36 has a guide surface 37 which is parallel to the transport direction 31 and is provided on a carrier 38 which is approximately triangular in plan. It can be folded away from the position shown in FIG. 1 into a rest position about a horizontal axis (not shown) lying perpendicular to the transport direction 31. For this purpose, a drive (not shown) is provided on the slide 32, for example in the form of a pneumatic cylinder. The stop ruler 36 is provided at the level of the cutter head 2, so that it does not become effective when the cutter head 1 is working.

In Transportrichtung 31 hinter dem Schieber 32 befindet sich der Schieber 35, der im wesentlichen gleich ausgebildet ist wie der Schieber 32. Der Schieber 35 trägt die beiden verti­kalen Spindeln 11, 12 mit den Messerköpfen 3, 4, den entsprechen­den Antriebsorganen und Andruckelementen. Der Schieber 35 kann ebenfalls senkrecht zur Transportrichtung 31 horizontal zwischen zwei Endlagen verstellt werden. In der in Fig. 1 darge­stellten einen Endlage befindet sich der Messerkopf 4 in Be­arbeitungsstellung, der beim Durchlauf der Hölzer deren linke Seite bearbeitet. Der andere Messerkopf 3 befindet sich wieder­um in der Ruhe- bzw. Wartungsstellung. Der Schieber 35 hat ebenfalls ein Anschlaglineal 39, das auf der dem Schieber 32 zugewandten Seite vorgesehen ist und einen im Umriß etwa drei­eckigen Träger 40 aufweist. Das Anschlaglineal 39 trägt an seiner der Tischplatte 18 zugewandten Längsseite zwei mit Ab­stand voneinander liegende Andruckrollen 41 und 42, die um vertikale Achsen frei drehbar sind. Beim Durchlauf der Hölzer liegen die Andruckrollen 41, 42 an der linken Seite der Hölzer an und drücken sie fest gegen die Anschlaglineale 19 und 20. In der in Fig. 1 dargestellten Arbeitslage liegen die Andruckrollen 41, 42 in Höhe des in Arbeitsstellung befind­lichen Messerkopfes 1. Dadurch werden die Hölzer in diesem Bereich einwandfrei geführt.In the direction of transport 31, behind the slide 32, there is the slide 35, which is essentially of the same design as the slide 32. The slide 35 carries the two vertical spindles 11, 12 with the cutter heads 3, 4, the corresponding drive elements and pressure elements. The slider 35 can also be adjusted horizontally between two end positions perpendicular to the transport direction 31. In the one end position shown in FIG. 1, the cutter head 4 is in the processing position, which processes the left side as the wood passes through. The other cutter head 3 is in turn in the rest or maintenance position. The slide 35 also has a stop ruler 39, which is provided on the side facing the slide 32 and has an approximately triangular support 40 in outline. The stop ruler 39 carries on its longitudinal side facing the table top 18 two pressure rollers 41 and 42 which are spaced apart and which can be freely rotated about vertical axes. When the woods pass through, the pressure rollers 41, 42 rest against the left side of the woods and press them firmly against the stop rulers 19 and 20. In the working position shown in FIG. 1, the pressure rollers 41, 42 lie at the level of the cutter head 1 in the working position As a result, the timbers are guided properly in this area.

In Transportrichtung 31 hinter den Andruckrollen 41, 42 und vor dem Messerkopf 4 ist der Schieber 35 mit einem Andrück­schuh 43 versehen, dessen Andrückfläche 44 in Transportrich­tung 31 schräg nach hinten und in den Transportweg geneigt verläuft. Die Andrückfläche 44 liegt ebenso wie die Andrück­fläche 34 in einer vertikalen Ebene.In the transport direction 31 behind the pressure rollers 41, 42 and in front of the cutter head 4, the slide 35 is provided with a pressure shoe 43, the pressure surface 44 of which runs obliquely backwards in the transport direction 31 and inclined in the transport path. The pressing surface 44, like the pressing surface 34, lies in a vertical plane.

Am Schieber 35 ist in Fig. 1 schematisch der Antrieb für die beiden Spindeln 11 und 12 dargestellt. Als Antrieb dient ein Riementrieb 45, dessen Riemen 46 über eine Riemenscheibe 47 auf der Vertikalspindel 12 und über eine Riemenscheibe 48 auf einer Antriebswelle 49 eines (nicht näher dargestellten) Motors geführt ist. Der Riemen 46 und die entsprechenden Spindeln bzw. Wellen sind so am Schieber 35 angeordnet, daß die Spindel 11 mit dem einen Trum des Riemens 46 in Berüh­rung gebracht werden kann. Hierzu ist es beispielsweise mög­lich, entweder die Spindel 11 oder die Antriebswelle 49 ver­stellbar am Schieber 35 vorzusehen, damit der Riemen 46 in der Arbeitsstellung des Messerkopfes 3 mit Spannung an der Spindel 11 anliegt und diese antreibt.On the slide 35 is the drive for the two spindles 11 and 12 shown. A belt drive 45 serves as the drive, the belt 46 of which is guided via a pulley 47 on the vertical spindle 12 and via a pulley 48 on a drive shaft 49 of a motor (not shown in more detail). The belt 46 and the corresponding spindles or shafts are arranged on the slide 35 so that the spindle 11 can be brought into contact with the one strand of the belt 46. For this purpose, it is possible, for example, to provide either the spindle 11 or the drive shaft 49 in an adjustable manner on the slide 35, so that the belt 46 rests with tension on the spindle 11 in the working position of the cutter head 3 and drives it.

Auf gleiche Weise lassen sich auch die Messerköpfe 1 und 2 des Schiebers 32 drehbar antreiben. Anstelle des Riementriebes können die Messerköpfe auch durch jeden anderen geeigneten Antrieb angetrieben werden, beispielsweise durch einen Ge­triebemotor.In the same way, the cutter heads 1 and 2 of the slide 32 can also be rotated. Instead of the belt drive, the cutter heads can also be driven by any other suitable drive, for example by a gear motor.

Auch die horizontalen Spindeln 13 bis 16 (Fig. 2) sind jeweils an einem Schieber 50 und 51 gelagert. Der Übersichtlichkeit wegen sind in Fig. 1 diese Schieber nicht dargestellt, während umgekehrt in Fig. 2 die Schieber 32 und 35 der Übersichtlich­keit wegen nicht engezeichnet worden sind. Die Schieber 50 und 51 sind senkrecht zur Transportrichtung 31 vertikal zwischen zwei Endstellungen verstellbar. Der Schieber 50 mit den Messerköpfen 5 und 6 sowie den Horizontalspindeln 13, 14 befindet sich in seiner unteren Endlage, so daß der Messer­kopf 5 seine Bearbeitungsstellung einnimmt, in der er die Oberseite der durchlaufenden Hölzer bearbeitet. Der untere Messerkopf 6 nimmt seine Ruhe- bzw. Wartungsstellung ein, in der er wiederum beispielsweise ausgewechselt oder seine Messer ausgetauscht oder nachgearbeitet werden können. Zum Antrieb der Messerköpfe bzw. Spindeln kann wiederum ein Riementrieb, ein Getriebemotor und dgl. verwendet werden. Die Antrieb- und Andruckelemente sind wiederum am Schieber 50 vorgesehen. Dadurch lassen sich - wie bei den Schiebern 32 und 35 - diese Teile genau zueinander einstellen, solange sich der eine Messerkopf in Arbeitsstellung befindet und die durchlaufenden Hölzer bearbeitet. In Transportrichtung 31 unmittelbar vor dem Messerkopf 5 befindet sich am Schieber 50 wiederum ein Andruckschuh 52, dessen Andruckfläche 53 in Transportrichtung 31 schräg nach unten und vorn verläuft. Mit dieser Andrück­fläche 53 liegt der Andruckschuh 52 auf der Oberseite der durchlaufenden Hölzer an und hält sie fest auf der Tischplatte 18. Der Andruckschuh 52 ist auf der den Schiebern 32, 35 zugewandten Seite des Schiebers 50 vorgesehen. Auf der gegenüber­liegenden Seite hat der Schieber 50 eine Druckschiene 54, die um eine horizontale, senkrecht zur Transportrichtung 31 liegende Achse 55 schwenkbar ist. Befindet sich der Messer­kopf 5 in seiner in Fig. 2 dargestellten Arbeitslage, dann ist die Druckschiene 54 nach unten in die horizontale Lage geschwenkt, so daß sie auf der Oberseite der durchlaufenden Hölzer aufliegt und diese während der Bearbeitung durch die Messerköpfe fest gegen die Tischplatte 18 drückt. Die Druck­schiene 54 kann beispielsweise durch einen (nicht dargestellten) Pneumatikzylinder verschwenkt werden, der ebenfalls am Schieber 50 angeordnet ist. In der Arbeitsstellung befindet sich die Druckschiene 54 in Transportrichtung 31 unmittelbar hinter dem Messerkopf 5 und im Bereich oberhalb des nachfolgenden Messerkopfes 8. Zweckmäßig läßt sich die Druckschiene 54 in der Höhe verstellen.The horizontal spindles 13 to 16 (FIG. 2) are each mounted on a slide 50 and 51. For the sake of clarity, these sliders are not shown in FIG. 1, whereas, conversely, the sliders 32 and 35 have not been shown in FIG. 2 for reasons of clarity. The sliders 50 and 51 can be adjusted vertically between two end positions perpendicular to the transport direction 31. The slider 50 with the cutter heads 5 and 6 and the horizontal spindles 13, 14 is in its lower end position, so that the cutter head 5 assumes its processing position in which it processes the top of the continuous wood. The lower cutter head 6 assumes its rest or maintenance position, in which it in turn, for example, exchanged or its knives can be exchanged or reworked. A belt drive, a gear motor and the like can in turn be used to drive the cutter heads or spindles. The drive and pressure elements are in turn provided on the slide 50. As with slides 32 and 35, these parts can be precisely adjusted to one another as long as one cutter head is in the working position and processes the continuous wood. In the transport direction 31 directly in front of the cutter head 5 there is again a pressure shoe 52 on the slide 50, the pressure surface 53 of which extends obliquely downwards and forwards in the transport direction 31. With this pressing surface 53, the pressure shoe 52 rests on the upper side of the continuous wood and holds it firmly on the table top 18. The pressure shoe 52 is provided on the side of the slide 50 facing the slides 32, 35. On the opposite side, the slide 50 has a pressure rail 54 which can be pivoted about a horizontal axis 55 lying perpendicular to the transport direction 31. If the cutter head 5 is in its working position shown in FIG. 2, then the pressure rail 54 is pivoted downward into the horizontal position so that it rests on the top of the continuous wood and this is firmly against the table top 18 during processing by the cutter heads presses. The pressure rail 54 can be pivoted, for example, by a pneumatic cylinder (not shown), which is also arranged on the slide 50. In the working position, the pressure rail 54 is located in the transport direction 31 directly behind the cutter head 5 and in the area above the subsequent cutter head 8. The height of the pressure rail 54 can expediently be adjusted.

Der Schieber 51 befindet sich gem. Fig. 2 in seiner oberen Endstellung, in der der Messerkopf 8 seine Arbeitsstellung einnimmt und die durchlaufenden Hölzer an der Unterseite be­arbeitet. Der Schieber 51 ist im wesentlichen gleich ausge­bildet wie der Schieber 50 und weist ebenfalls eine Druck­schiene 56 auf, die auf der dem Schieber 50 zugewandten Seite des Schiebers 51 vorgesehen und ebenfalls um eine horizontale Achse schwenkbar ist. Da sich der Schieber 51 in seiner oberen Endlage befindet, ist die Druckschiene 56 in ihre vertikale Ruhestellung geschwenkt und nicht wirksam. Sie liegt in der Ruhestellung im Bereich oberhalb der Druck­schiene 54. Da die beiden auf den einander zugewandten Seiten der Schieber 50, 51 angeordneten Druckschienen 54 und 56 je­weils um die horizontale, senkrecht zur Transportrichtung 31 verlaufenden Achsen schwenkbar sind, lassen sich die Schieber 50, 51 verhältnismäßig nahe nebeneinander an der Kehlmaschine anordnen. Werden die Schieber 50, 51 verstellt, werden zuvor die Druckschienen 54, 56 in die vertikale Ruhelage geschwenkt, so daß die Schieber aneinander vorbeibewegt werden können.The slide 51 is gem. Fig. 2 in its upper End position in which the cutter head 8 assumes its working position and processes the continuous wood on the underside. The slide 51 is essentially of the same design as the slide 50 and also has a pressure rail 56 which is provided on the side of the slide 51 facing the slide 50 and is also pivotable about a horizontal axis. Since the slide 51 is in its upper end position, the pressure rail 56 is pivoted into its vertical rest position and is not effective. It lies in the rest position in the area above the pressure rail 54. Since the two pressure rails 54 and 56 arranged on the mutually facing sides of the sliders 50, 51 can each be pivoted about the horizontal axes running perpendicular to the transport direction 31, the sliders 50, 51 relatively close to each other on the moulder. If the slides 50, 51 are adjusted, the pressure rails 54, 56 are pivoted into the vertical rest position beforehand, so that the slides can be moved past one another.

Auf der vom Schieber 50 abgewandten Seite ist der Schieber 51 mit einer weiteren Druckschiene 57 versehen, die kürzer ist als die Druckschiene 56 und in Transportrichtung 31 un­mittelbar hinter dem Messerkopf 7 liegt. Die Druckschiene 57 ist lediglich in Höhenrichtung verstellbar, nicht jedoch um eine horizontale Achse schwenkbar.On the side facing away from the slide 50, the slide 51 is provided with a further pressure rail 57, which is shorter than the pressure rail 56 and is located directly behind the cutter head 7 in the transport direction 31. The pressure rail 57 can only be adjusted in the vertical direction, but cannot be pivoted about a horizontal axis.

Die Spindeln 9 und 10 bzw. 11 und 12 auf den Schiebern 32 und 35 liegen in einer gemeinsamen, senkrecht zur Transportrich­tung 31 liegenden Vertikalebene. Die Spindeln 13, 14 bzw. 15, 16 der Schieber 50 und 51 sind hingegen geringfügig in Transportrichtung 31 gegeneinander versetzt. Dabei liegen die Spindeln 13 und 16 jeweils näher zum Schieber 35 als die anderen Spindeln 14 und 15 auf den beiden Schiebern 50 und 51 (Fig. 1). Es ist aber durchaus auch möglich, auch die paarweise angeordneten Spindeln der Schieber 50 und 51 je­weils in einer gemeinsamen Ebene anzuordnen.The spindles 9 and 10 or 11 and 12 on the slides 32 and 35 lie in a common vertical plane lying perpendicular to the transport direction 31. The spindles 13, 14 and 15, 16 of the slide 50 and 51, however, are slightly offset from each other in the transport direction 31. The spindles 13 and 16 are each closer to the slide 35 than that other spindles 14 and 15 on the two sliders 50 and 51 (Fig. 1). However, it is also entirely possible to arrange the spindles of the slides 50 and 51, which are arranged in pairs, in each case in a common plane.

Bei der in den Fig. 1 und 2 dargestellten Lage der Schieber 32, 35, 50 und 51 werden die durch die Kehlmaschine trans­portierten Hölzer nach dem Abrichten an ihrer Unterseite durch das Abrichtwerkzeug 30 zunächst durch den Messerkopf 1 an ihrer rechten Seite, anschließend durch den Messerkopf 4 an ihrer linken Seite, durch den Messerkopf 5 an der Ober­seite und schließlich durch den Messerkopf 8 an der Unter­seite bearbeitet. Wenn die Hölzer die Kehlmaschine ver­lassen, sind sie an allen vier Seiten in der gewünschten Weise bearbeitet. Das Anschlaglineal 39, das sich gegenüber dem Messerkopf 1 befindet, kann zur Anpassung an unterschied­lich breite Hölzer quer zur Transportrichtung 31 verstellt werden, so daß die Hölzer durch die Andruckrollen 41, 42 sicher gegen die Anschlaglineale 19, 20 gedrückt werden. Im Bereich der Vertikalspindeln liegen die Andruckrollen 41, 42 und der Andrückschuh 43 mit nur geringem Abstand hinterein­ander, so daß die Hölzer auf dieser Seite bei der Bearbeitung zuverlässig geführt werden. Auch im Bereich der Horizontal­spindeln werden die Hölzer durch die dicht aufeinanderfolgenden Elemente 52, 54 einwandfrei geführt. Außerdem sorgen die Vor­schubrollen 22 dafür, daß die Hölzer gegen die Tischplatte 18 gedrückt und dadurch zuverlässig geführt werden. Der Trägerteil 27 ist, wie Fig. 2 zeigt, in seine rechte End­stellung verfahren, so daß die in Fig. 2 rechte Vorschubrolle 22 des Trägerteiles im Bereich oberhalb des in Arbeitsstellung befindlichen Messerkopfes 8 liegt. Dadurch ist auch der Ab­stand zwischen dieser Vorschubrolle 22 und der in Transport­ richtung 31 vorangehenden Druckschiene 54 gering, so daß die Hölzer auch in diesem Bereich einwandfrei geführt und transportiert werden.In the position of the slides 32, 35, 50 and 51 shown in FIGS. 1 and 2, the wood transported by the moulder after dressing on its underside by the dressing tool 30 is first by the cutter head 1 on its right side, then by the Knife head 4 on its left side, processed by the knife head 5 on the top and finally by the knife head 8 on the bottom. When the woods leave the moulder, they are machined on all four sides in the desired way. The stop ruler 39, which is located opposite the cutter head 1, can be adjusted transversely to the transport direction 31 in order to adapt to wood of different widths, so that the woods are pressed securely against the stop rulers 19, 20 by the pressure rollers 41, 42. In the area of the vertical spindles, the pressure rollers 41, 42 and the pressure shoe 43 are only a short distance behind one another, so that the woods are reliably guided on this side during processing. Even in the area of the horizontal spindles, the timbers are guided correctly by the closely spaced elements 52, 54. In addition, the feed rollers 22 ensure that the woods are pressed against the table top 18 and thereby reliably guided. As shown in FIG. 2, the carrier part 27 has moved into its right end position, so that the right-hand feed roller 22 of the carrier part in FIG. 2 lies in the area above the cutter head 8 in the working position. As a result, the distance between this feed roller 22 and that in transport direction 31 preceding pressure rail 54 low, so that the woods are properly guided and transported in this area.

Die Schieber 32, 35, 50 und 51 sind in (nicht näher dargestellten) Führungen der Kehlmaschine einwandfrei in horizontaler bzw. vertikaler Richtung quer zur Transportrichtung 31 verstellbar. Im einfachsten Falle werden die Schieber, wie zuvor beschrieben, in zwei Endlagen verschoben, so daß eine genaue Positionierung der jeweiligen Messerköpfe einfach möglich ist. Bei einer bevorzugten Lösung hingegen werden die Schieber 32, 35, 50 und 51 durch Positioniermotoren verstellt, die eine gezielte Verstellung der Schieber ermöglichen. Dadurch ist in einfacher Weise eine genaue Anpassung an unterschiedlich dicke und hohe Hölzer möglich.The slides 32, 35, 50 and 51 can be adjusted in the (not shown in detail) guides of the moulder perfectly in the horizontal or vertical direction transversely to the transport direction 31. In the simplest case, the slides are moved to two end positions, as described above, so that the respective cutter heads can be precisely positioned. In a preferred solution, on the other hand, the slides 32, 35, 50 and 51 are adjusted by positioning motors, which enable the slides to be adjusted in a targeted manner. As a result, an exact adaptation to wood of different thicknesses and heights is possible in a simple manner.

Sollen beispielsweise die Messer der Messerköpfe 1 und 4 nachgearbeitet werden, dann brauchen lediglich die Schieber 32 und 35 so verschoben zu werden, daß die anderen Messerköpfe 2 bzw. 3 in die Arbeitsstellung gelangen. Dann kann mit der Kehl­maschine weitergearbeitet werden, während an den in der Ruhestel­lung befindlichen Messerköpfen 1 und 4 die Messer nachgearbeitet werden. Beim Verstellen der Schieber 32 und 35 sind die Anschlag­lineale 36 und 39 hochgeklappt. Wenn sich der Messerkopf 2 in seiner Arbeitsstellung befindet, dann kann das Anschlaglineal 36 nach unten geklappt werden. Es liegt dann dem Messerkopf 3 gegenüber. Die durch die Kehlmaschine laufenden Hölzer werden in dieser Stellung der Schieber 32, 35 zunächst an der linken Seite und anschließend an der rechten Seite bearbeitet.If, for example, the knives of the knife heads 1 and 4 are to be reworked, then only the slides 32 and 35 need to be shifted so that the other knife heads 2 and 3 come into the working position. Then you can continue working with the moulder while the knives are being reworked on the knife heads 1 and 4 which are in the rest position. When adjusting the slide 32 and 35, the stop rulers 36 and 39 are folded up. When the cutter head 2 is in its working position, the stop ruler 36 can be folded down. It is then opposite the cutter head 3. In this position, the wood passing through the molding machine is first processed on the left side and then on the right side.

In gleicher Weise lassen sich auch die Schieber 50 und 51 verstellen, so daß die jeweils anderen Messerköpfe 6 und 7 in die Arbeitsstellung gelangen. In diesem Falle werden die Hölzer zunächst mit dem Messerkopf 6 an der Unterseite und anschließend mit dem Messerkopf 7 an der Oberseite bearbei­tet.The slides 50 and 51 can also be adjusted in the same way, so that the respective other cutter heads 6 and 7 get into the working position. In this case, the woods are first processed with the cutter head 6 on the underside and then with the cutter head 7 on the top.

Die Schieber 32, 35, 50 und 51 lassen sich unabhängig vonein­ander verstellen, so daß die Hölzer mit den verschiedenen Messerköpfen auf die unterschiedlichste Weise bearbeitet werden können. So ist es beispielsweise möglich, den Messer­kopf 1 und den Messerkopf 3 in die Arbeitsstellung zu ver­schieben, so daß die Hölzer beim Durchlaufen von beiden Messer­köpfen nur an der rechten Seite bearbeitet werden. Auch ist es beispielsweise möglich, die Schieber 50, 51 so einzustellen, daß die Hölzer nur an der Ober- oder nur an der Unterseite von den entsprechenden Messerköpfen bearbeitet werden. Auf diese Weise ist eine große Zahl von Einstellmöglichkeiten gegeben. Die Kehlmaschine kann darüberhinaus noch weitere vertikal und/oder horizontal verstellbare Schieber mit ent­sprechenden Messerköpfen aufweisen, so daß sich die Einsatz­möglichkeiten dieser Kehlmaschine erheblich erweitern lassen.The slides 32, 35, 50 and 51 can be adjusted independently of one another, so that the wood can be processed in a wide variety of ways with the various cutter heads. For example, it is possible to move the cutter head 1 and cutter head 3 into the working position, so that the woods are only processed on the right-hand side when they pass through both cutter heads. It is also possible, for example, to adjust the slides 50, 51 in such a way that the woods are processed only on the top or only on the bottom by the corresponding cutter heads. In this way, there is a large number of setting options. The moulder can also have further vertically and / or horizontally adjustable slides with corresponding cutter heads, so that the possible uses of this moulder can be expanded considerably.

Da auf jedem Schieber jeweils zwei Messerköpfe mit den zuge­hörigen Antriebs- und Andrückelementen vorgesehen sind, sind die Umrüstzeiten der Kehlmaschine äußerst gering. Während sich die einen Messerköpfe in Arbeitsstellung befinden und die durchlaufenden Hölzer bearbeiten, können an den in Ruhe- bzw. Wartungsstellung befindlichen Messerköpfen eventuell erforderliche Reparaturarbeiten durchgeführt werden. Außer­dem können in dieser Ruhestellung die Messerköpfe mit den Andrückelementen so eingestellt werden, daß bei einem späteren Verstellen dieser Messerköpfe in die Arbeitsstellung lediglich die Schieber verschoben werden müssen, ohne daß dann noch Positionierarbeiten erforderlich sind. Auf diese Weise können die Stillstandszeiten der Kehlmaschine für diesen Umrüstvorgang sehr gering gehalten werden.Since two knife heads with the associated drive and pressure elements are provided on each slide, the changeover times of the moulder are extremely short. While one cutter head is in the working position and is processing the continuous wood, any necessary repair work can be carried out on the cutter heads in the rest or maintenance position. In addition, the knife heads with the pressing elements can be adjusted in this rest position so that when these knife heads are later adjusted to the working position, only the slides have to be moved without then positioning work is still required. In this way, the downtimes of the moulder can be kept very short for this changeover process.

Durch den in Transportrichtung verstellbaren Trägerteil 27 ist sichergestellt, daß die Hölzer auch im Bereich des Schiebers 51 zuverlässig von den Vorschubrollen 22 erfaßt und transportiert werden können. Wird der Messerkopf 7 in seine Arbeitslage gebracht, wird zuvor der Trägerteil 27 in Fig. 2 nach links in die mit gestrichelten Linien angedeutete Lage verschoben. Dann läßt sich der Messerkopf 7 mühelos in seine Arbeitslage verstellen. Sofern die zugehörigen Schieber 32 und 35 bzw. 50 und 51 jeweils eine gleiche Lage einnehmen, sind selbstverständlich die entsprechenden Druckschienen bzw. Anschlaglineale, die im Bewegungsweg des jeweils anderen Schiebers liegen, hochgeklappt.The support part 27, which is adjustable in the transport direction, ensures that the woods can also be reliably gripped and transported by the feed rollers 22 in the region of the slide 51. If the cutter head 7 is brought into its working position, the carrier part 27 in FIG. 2 is first shifted to the left into the position indicated by dashed lines. Then the cutter head 7 can be easily adjusted into its working position. If the associated slides 32 and 35 or 50 and 51 each occupy the same position, the corresponding pressure rails or stop rulers, which lie in the path of movement of the respective other slider, are of course folded up.
