Description

Die Erfindung betrifft eine Jointeinrichtung nach dem Oberbegriff des Anspruches 1.The invention relates to a join device according to the preamble of claim 1.

Solche Jointeinrichtungen dienen dazu, die Werkzeuge eines Werkzeugträgers, insbesondere die Messer eines Messerkopfes, so zu bearbeiten, daß alle Schneiden der Messer des Messerkopfes einen absolut einheitlichen Flugkreis haben. Ein Geradjointstein wird zum Jointen, d.h. zum Abziehen der Messer des Messerkopfes, bis auf deren Flugkreis zugestellt. Bei rotierendem Messerkopf werden dann die Schneiden der Messer abgezogen (gejointet). Der Geradjointer kann parallel zur Achse des Werkzeugträgers verstellt werden. Nun haben die Messer jedoch nicht immer gerade Schneiden, sondern können auch als Profilmesser ausgebildet sein, deren Schneiden eine dem herzustellenden Profil entsprechende Formgebung haben. Um solche Messer jointen zu können, müssen gesonderte Profiljointsteine eingesetzt werden.Such join devices are used to machine the tools of a tool holder, in particular the knives of a cutter head, in such a way that all cutting edges of the cutters of the cutter head have an absolutely uniform flight circle. A straight joint stone becomes a join, i.e. for removing the knives of the cutter head, down to their flight circle. When the knife head rotates, the cutting edges of the knives are then removed (jointed). The straight jointer can be adjusted parallel to the axis of the tool carrier. However, the knives do not always have straight cutting edges, but can also be designed as profile knives, the cutting edges of which have a shape corresponding to the profile to be produced. In order to join such knives, separate profile joint stones must be used.

Bei der gattungsgemäßen Jointeinrichtung (US-A-4 512 114) wird der Jointstein auf einem Horizontalschieber gespannt, der gegen das rotierende Werkzeug zugestellt werden kann. Mit dieser bekannten Jointeinrichtung können gerade und profilierte Schneiden der Werkzeuge gejointet werden. Da sich der Jointstein jedoch nur senkrecht zur Achse des Werkzeuges zustellen läßt, ist ein gutes Geradjointen nicht möglich. Schon kleinste Abnutzungen oder Ausbrüche des Jointsteines führen bei der ausschließlich radialen Zustellung dazu, daß sich diese Verschleißerscheinungen des Jointsteines an den gejointeten Werkzeugschneiden abbilden.In the case of the generic join device (US-A-4 512 114), the joint stone is clamped on a horizontal slide which can be advanced against the rotating tool. With this known join device, straight and profiled cutting of the Tools to be jointed. However, since the joint stone can only be fed perpendicular to the axis of the tool, good straight line alignment is not possible. Even the smallest wear or chipping of the joint stone with the exclusively radial infeed means that these signs of wear of the joint stone are reflected on the jointed cutting edges.

Der Erfindung liegt die Aufgabe zugrunde, die gattungsgemäße Jointeinrichtung so auszubilden, daß sowohl ein Geradjointen als auch ein Profiljointen mit hoher Genauigkeit möglich ist, wobei die Jointeinrichtung einen einfachen und kompakten Aufbau aufweisen soll.The invention has for its object to design the generic join device so that both a straight join and a profile join with high accuracy is possible, the join device should have a simple and compact structure.

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

Bei der erfindungsgemäßen Jointeinrichtung wird der Träger, der den Jointstein aufweist, mittels des Schwingkörpers für einen Profijointvorgang quer zur Achse des Werkzeugträgers mit Vorschubgeschwindigkeit geschwenkt. Dabei wird das Werkzeug im gewünschten Maße abgezogen (gejointet). Zur Durchführung eines Geradjointvorganges läßt sich der Träger parallel zur Achse des Werkzeugträgers verstellen. Da der Jointstein während des Abziehvorganges parallel zur Werkzeugträgerachse verschoben wird, wirken sich Abnutzungen oder Ausbrüche des Jointsteines nicht auf die Genauigkeit der gejointeten Werkzeuge aus. Bei der Axialverschiebung kommen auf jeden Fall noch unverschlissene Bereiche des Jointsteines mit dem zu jointenden Werkzeug in Berührung, das dadurch sehr genau abgezogen werden kann. Die erfindungsgemäße Jointeinrichtung wird bevorzugt bei Holzbearbeitungsmaschinen, insbesondere bei Kehlmaschinen, eingesetzt.In the join device according to the invention, the carrier, which has the joint stone, is pivoted transversely to the axis of the tool carrier at a feed rate by means of the oscillating body for a professional joint process. The tool is then pulled off (jointed) to the desired extent. The carrier can be adjusted parallel to the axis of the tool carrier to carry out a straight joint process. Since the joint stone is moved parallel to the tool carrier axis during the pulling process, wear or chipping of the joint stone does not affect the accuracy of the jointed tools. During the axial displacement, areas of the joint stone that are not yet worn definitely come into contact with the tool to be joined, which can be removed very precisely as a result. The join device according to the invention is preferably used in woodworking machines, in particular in moulders.

Bei einer Ausbildung entsprechend Anspruch 6 ergibt sich eine besonders kompakte Ausbildung der erfindungsgemäßen Jointeinrichtung. Mit den beiden Jointsteinen läßt sich bei kompakter Ausbildung das Werkzeug ohne Schwierigkeiten über seine gesamte Länge abziehen.With a design according to claim 6, a particularly compact design of the join device according to the invention results. With the two joint stones, the tool can be easily pulled off over its entire length with a compact design.

Weitere Merkmale der Erfindung ergeben sich aus den weiteren Ansprüchen.Further features of the invention result from the further claims.

Die Jointeinrichtung hat einen Grundkörper 1, der im Axialschnitt gem. Fig. 1 U-Form hat. Zwischen seinen beiden Schenkeln 2 und 3 ist ein Schwingkörper 4 schwenkbar gelagert. An den freien Enden seiner Schenkel 5, 6 sind Drehachsen 7 und 8 vorgesehen, mit denen der Schwingkörper 4 nahe den freien Enden der Schenkel 2, 3 des Grundkörpers 1 schwenkbar gelagert ist. Die Drehachse 8 durchsetzt den Schenkel 3 des Grundkörpers 1 und trägt auf ihrem freien Ende drehfest eine Nachstelleinrichtung 9. Der Quersteg 10 des Schwingkörpers 4 ist mit einer Verschiebeführung 11, vorzugsweise mit einem Schwalbenschwanz (Fig. 2), versehen, längs der ein Träger 12 für Jointsteine 13 verschiebbar ist. Wie Fig. 2 zeigt, liegen die Jointsteine 13 auf einer Auflage 14 auf und sind durch eine Halteleiste 15, die mit Gewindebolzen 16 befestigt ist, gehalten. Mit den Jointsteinen 13 werden die (nicht dargestellten) Messerschneiden eines Messerkopfes 17 gejointet, d. h. mit den Jointsteinen abgezogen. Die Auflage 14 ist Teil einer Halterung 18, die auf dem Träger 12 gehalten ist. Die Gewindebolzen 16 zum Befestigen der Halteleiste 15 sind in die Halterung 18 geschraubt. Sie wird mit Klemmschrauben 19 in einer schwalbenschwanzförmigen Nut 20 des Trägers 12 festgeklemmt. Die Klemmschrauben 19 sind in einem leistenförmigen Vorsprung 21 des Trägers 12 gehalten. Infolge der schwalbenschwanzförmigen Nut 20 ist sichergestellt, daß die Halterung 18, die mit einem entsprechenden Ansatz 22 formschlüssig in der Nut gehalten ist, nicht unbeabsichtigt aus ihr herausgedrückt werden kann.The join device has a base body 1 which, according to the axial section. Fig. 1 has a U-shape. Between its two legs 2 and 3, a vibrating body 4 is pivotally mounted. At the free ends of its legs 5, 6, axes of rotation 7 and 8 are provided, with which the oscillating body 4 is pivotably mounted near the free ends of the legs 2, 3 of the base body 1. The axis of rotation 8 passes through the leg 3 of the base body 1 and carries an adjusting device 9 on its free end in a rotationally fixed manner is movable for joint stones 13. As shown in FIG. 2, the joint stones 13 rest on a support 14 and are held by a retaining bar 15 which is fastened with threaded bolts 16. With the joint stones 13, the knife edges (not shown) of a knife head 17 are jointed, that is, pulled off with the joint stones. The pad 14 is part of a bracket 18, the is held on the carrier 12. The threaded bolts 16 for fastening the retaining bar 15 are screwed into the holder 18. It is clamped with clamping screws 19 in a dovetail groove 20 of the carrier 12. The clamping screws 19 are held in a strip-shaped projection 21 of the carrier 12. As a result of the dovetail-shaped groove 20, it is ensured that the holder 18, which is held in the groove in a form-fitting manner with a corresponding extension 22, cannot be inadvertently pressed out of it.

Der Träger 12 mit den Jointsteinen 13 kann längs der Verschiebeführung 11 mittels eines Antriebes 23 verschoben werden. Als Antrieb ist im Ausführungsbeispiel eine Kolben-Zylinder-Einheit vorgesehen, deren Zylinder 24 am Grundkörper und deren parallel zur Verschiebeführung 11 verlaufende Kolbenstange 25 mit ihrem freien Ende an einem Vorsprung 26 des Trägers 12 befestigt ist. In Fig. 1 ist der Träger 12 in seiner rechten Endstellung dargestellt, in der die Kolbenstange 25 eingefahren ist. Durch Ausfahren der Kolbenstange 25 kann der Träger 12 mit den Jointsteinen 13 längs der Verschiebeführung 11 verschoben werden. Eine solche Axialbewegung wird vorgenommen, wenn mit den Jointsteinen 13 ein Geradjointvorgang durchgeführt wird. Hierbei werden die Jointsteine 13 an den abzuziehenden Messerschneiden vorbeigefahren.The carrier 12 with the joint stones 13 can be displaced along the displacement guide 11 by means of a drive 23. In the exemplary embodiment, a piston-cylinder unit is provided as the drive, the free end of the cylinder 24 of which is attached to a projection 26 of the carrier 12 on the base body and the piston rod 25 which runs parallel to the displacement guide 11. In Fig. 1, the carrier 12 is shown in its right end position, in which the piston rod 25 is retracted. By extending the piston rod 25, the carrier 12 with the joint stones 13 can be displaced along the displacement guide 11. Such an axial movement is carried out when a straight joint process is carried out with the joint stones 13. Here, the joint stones 13 are moved past the knife edges to be removed.

Mittels der Halteleiste 15 und der Gewindebolzen 16 lassen sich die Jointsteine 13 sehr einfach austauschen oder gegen andere Jointsteine auswechseln.By means of the retaining strip 15 and the threaded bolts 16, the joint stones 13 can be exchanged very easily or can be exchanged for other joint stones.

Um mit den Jointsteinen 13 auch Profile abziehen zu können, kann der Schwingkörper 4 um die Drehachsen 7, 8 mit einem (nicht dargestellten) Antrieb in Richtung des Doppelpfeiles 27 in Fig. 2 geschwenkt werden. Fig. 2 zeigt die zurückgeschwenkte Endlage des Schwingkörpers 4, in der die Jointsteine 13 den größten Abstand vom Messerkopf 17 haben. Um einen Profiljointvorgang durchzuführen, wird der Schwingkörper 4 mit diesem Antrieb in Schwenkrichtung 27 gegen den Messerkopf 17 mit Vorschubgeschwindigkeit bis auf den Profilgrund des Messers geschwenkt. Dabei werden die jeweiligen Messerschneiden in gewünschtem Maße abgezogen. Nach dem Abziehvorgang (Jointvorgang) wird die Jointeinrichtung automatisch nachgestellt, so daß bei einem nachfolgenden Jointvorgang die Messer wiederum exakt abgezogen werden. Für diese vollautomatische Nachstellung ist die Nachstelleinrichtung 9 vorgesehen, die anhand der Figuren 3 und 4 näher erläutert werden soll.In order to be able to remove profiles with the joint stones 13, the oscillating body 4 can rotate about the axes of rotation 7, 8 with a drive (not shown) in the direction of the double arrow 27 are pivoted in Fig. 2. FIG. 2 shows the pivoted-back end position of the oscillating body 4, in which the joint stones 13 are at the greatest distance from the cutter head 17. In order to carry out a profile joining process, the oscillating body 4 is pivoted with this drive in the pivoting direction 27 against the cutter head 17 at a feed rate up to the profile base of the cutter. The respective knife edges are subtracted to the desired extent. After the pull-off process (joint process), the join device is automatically adjusted so that the knives are again pulled off exactly in a subsequent joint process. For this fully automatic adjustment, the adjustment device 9 is provided, which will be explained in more detail with reference to FIGS. 3 and 4.

Die Nachstelleinrichtung 9 hat einen blockförmigen Korpus 29, in dem die zur Nachstellung erforderlichen Bauteile geschützt untergebracht sind. Im Korpus 29 ist eine Spindel 30 drehbar gelagert, die auf der vom Messerkopf 17 abgewandten Seite aus dem Korpus 29 ragt und ein Griffstück 31, vorzugsweise eine Rändelscheibe, trägt. Mit ihr kann die Spindel 30 von Hand gedreht werden. Innerhalb des Korpus 29 sitzt auf der Spindel 30 ein Klinkenrad 32, das mit einer im Korpus 29 schwenkbar gelagerten Klinke 33 zusammenwirken kann. Die Spindel 30 mit dem Klinkenrad 32 ist durch eine Verschlußplatte 34 axial gesichert, die auf dem Korpus 29 lösbar befestigt ist. Um eine Fixierung des Klinkenrades 32 zu erreichen, ist im Korpus 29 eine Rasteinrichtung 35 untergebracht. Sie hat einen unter Federkraft in das Klinkenrad 32 eingreifenden Sperrkörper 36, der in einer napfförmigen Aufnahme 37 gelagert ist. Die Aufnahme 37 ragt aus dem Korpus 29 und ist vorzugsweise in ihn geschraubt, so daß sie bei Beschädigung oder Verschleiß einfach ausgetauscht werden kann.The adjusting device 9 has a block-shaped body 29 in which the components required for the adjustment are accommodated in a protected manner. A spindle 30 is rotatably mounted in the body 29, which projects out of the body 29 on the side facing away from the cutter head 17 and carries a handle 31, preferably a knurled disk. With it, the spindle 30 can be turned by hand. A ratchet wheel 32 is seated on the spindle 30 within the body 29 and can cooperate with a pawl 33 pivotably mounted in the body 29. The spindle 30 with the ratchet wheel 32 is axially secured by a locking plate 34 which is releasably attached to the body 29. In order to fix the ratchet wheel 32, a latching device 35 is accommodated in the body 29. It has a locking body 36 which engages with the ratchet wheel 32 under spring force and is mounted in a cup-shaped receptacle 37. The receptacle 37 protrudes from the body 29 and is preferably screwed into it so that it can be easily replaced in the event of damage or wear.

Die Klinke 33 ist an einem quer zur Achse 38 der Spindel 30 und des Klinkenrades 32 verschiebbaren Druckglied 39 gelagert, das mit einem Betätigungsglied 40 aus dem Korpus 29 ragt. Das Druckglied 39 ist in einer Öffnung 41 des Korpus gegen die Kraft einer Druckfeder 42 verschiebbar gelagert. Die Druckfeder 42 stützt sich mit einem Ende an einem Bund 43 des Druckgliedes 39 und mit dem anderen Ende an einem Absatz 44 der Wandung der Öffnung 41 ab. Mit dem Bund 43 ist das Druckglied 39 in einem im Durchmesser erweiterten Bereich 45 der Öffnung 41 geführt. Die Druckfeder 42 umgibt einen Schaft 46 des Druckgliedes 39, der in einem an den Absatz 44 anschließenden, im Durchmesser verringerten Bereich 47 der Öffnung 41 geführt ist. Vom Schaft 46 ragen in Richtung auf einen das Klinkenrad 32 aufweisenden Aufnahmeraum 48 im Korpus 29 zwei Laschen 49, zwischen denen die Klinke 33 schwenkbar gelagert ist.The pawl 33 is mounted on a pressure member 39 which is displaceable transversely to the axis 38 of the spindle 30 and the ratchet wheel 32 and which projects from the body 29 with an actuating member 40. The pressure member 39 is slidably mounted in an opening 41 of the body against the force of a compression spring 42. The compression spring 42 is supported at one end on a collar 43 of the pressure member 39 and at the other end on a shoulder 44 of the wall of the opening 41. With the collar 43, the pressure member 39 is guided in an enlarged diameter region 45 of the opening 41. The compression spring 42 surrounds a shaft 46 of the pressure member 39, which is guided in a region 47 of the opening 41 which adjoins the shoulder 44 and has a reduced diameter. Two straps 49 project from the shaft 46 in the direction of a receiving space 48 in the body 29 which has the ratchet wheel 32 and between which the pawl 33 is pivotably mounted.

Zur Verdrehsicherung des Druckgliedes 39 dient ein Sperrstift 50, der in einer oberhalb des Absatzes 44 in den schmaleren Bereich 47 der Öffnung 41 mündenden Querbohrung 51 im Korpus 29 untergebracht ist. Der Schaft 46 des Druckgliedes 39 hat eine axial verlaufende Nut 52, in welche der Sperrstift 50 eingreift. In der in Fig. 4 dargestellten unteren Endstellung liegt der Sperrstift 50 unter der Kraft der Druckfeder 42 an dem der Klinke 33 zugewandten Ende 53 der Nut 52 an.A locking pin 50, which is accommodated in a transverse bore 51 in the body 29 opening above the shoulder 44 into the narrower region 47 of the opening 41, serves to secure the pressure member 39 against rotation. The shaft 46 of the pressure member 39 has an axially extending groove 52, in which the locking pin 50 engages. In the lower end position shown in FIG. 4, the locking pin 50 bears against the end 53 of the groove 52 facing the pawl 33 under the force of the compression spring 42.

In dieser unteren Endstellung wird die Klinke 33 durch die Kraft einer Feder 54 mit einer Anschlagfläche 55 gegen eine Gegenanschlagfläche 56 gedrückt. Beide Flächen 55, 56 haben vorzugsweise senkrecht zur Achse des Schaftes 46 verlaufende Erzeugende. In dieser Anschlagstellung hat die Klinke 33 Abstand vom Klinkenrad 32. Die Feder 54 ist vorzugsweise eine Blattfeder, die an einer Wandung des Aufnahmeraumes 48 des Korpus 29 befestigt ist.In this lower end position, the pawl 33 is pressed by the force of a spring 54 with a stop surface 55 against a counter stop surface 56. Both surfaces 55, 56 preferably have generatrixes running perpendicular to the axis of the shaft 46. In this stop position, the pawl 33 is at a distance from the ratchet wheel 32. The spring 54 is preferably one Leaf spring which is attached to a wall of the receiving space 48 of the body 29.

Der Klinke 33 liegt in der Anschlagstellung gem. Fig. 4 mit Abstand ein Anschlag 57 gegenüber, der vorzugsweise durch einen Gewindebolzen gebildet ist. Er ragt in den Aufnahmeraum 48 und ist in eine Gewindebohrung 58 des Korpus 29 geschraubt. Auf dem aus dem Korpus 29 ragenden Ende des Anschlages 57 sitzt eine Mutter 59, mit der der Anschlag 57 in der jeweiligen Lage gesichert wird. Mit dem als Gewindebolzen ausgebildeten Anschlag 57 kann der Abstand zur Klinke 33 stufenlos eingestellt werden. Die Achsen des Anschlages 57 und des Druckgliedes 39 liegen parallel zueinander sowie senkrecht zur Achse 38 der Spindel 30. Die Schwenkachse 60 der Klinke 33 liegt auf der die Achse des Druckgliedes 39 enthaltenden Ebene E sowie parallel zur Achse 38 der Spindel 30.The pawl 33 is in the stop position acc. Fig. 4 at a distance from a stop 57, which is preferably formed by a threaded bolt. It protrudes into the receiving space 48 and is screwed into a threaded bore 58 of the body 29. On the end of the stop 57 protruding from the body 29 there is a nut 59 with which the stop 57 is secured in the respective position. With the stop 57 designed as a threaded bolt, the distance to the pawl 33 can be adjusted continuously. The axes of the stop 57 and the pressure element 39 are parallel to one another and perpendicular to the axis 38 of the spindle 30. The pivot axis 60 of the pawl 33 lies on the plane E containing the axis of the pressure element 39 and parallel to the axis 38 of the spindle 30.

Wird das Druckglied 39 über das Betätigungsglied 49 gegen die Kraft der Druckfeder 42 in den Korpus 29 gedrückt, wird die Klinke 33 in Richtung auf den Anschlag 57 geschoben. Da die Klinke 33 durch die Feder 54 stets in Richtung auf das Klinkenrad 32 belastet ist, wird sie beim Verschieben des Druckgliedes in Eingriff in das Klinkenrad 32 geschwenkt, sobald ihre Anschlagfläche 54 von der Gegenanschlagfläche 56 freikommt. Dies ist der Fall, bevor die Klinke 33 am Anschlag 57 zur Anlage kommt. Der noch zur Verfügung stehende Verschiebeweg des Druckgliedes 39 bzw. der Klinke 33 reicht aus, um das Klinkenrad 32 und damit die Spindel 30 zu drehen. Der Sperrkörper 36 ratscht hierbei über die Zähne des Klinkenrades 32. Die Drehbewegung der Spindel 33 ist beendet, sobald die Klinke 33 am Anschlag 57 zur Anlage kommt. Durch den Abstand zwischen dem Anschlag 57 und der in Anschlagstellung befindlichen Klinke 33 läßt sich sehr einfach der Drehweg des Klinkenrades 32 einstellen. Je größer der Abstand zwischen dem Anschlag 57 und der Klinke 33 ist, desto mehr kann das Klinkenrad 32 beim Verschieben des Druckgliedes 39 gedreht werden. Sobald das Druckglied 39 freigegeben wird, wird es unter der Kraft der Druckfeder 42 wieder in seine Ausgangslage gem. Fig. 4 zurückgeschoben. Die Klinke 33 kommt hierbei außer Eingriff mit dem Klinkenrad 32 und gelangt in die Anschlagstellung gem. Fig. 4, in der es mit seiner Anschlagfläche 55 unter der Kraft der Feder 54 an der Gegenanschlagfläche 56 anliegt. Die Sperreinrichtung 35 verhindert, daß das Klinkenrad 32 nach der Freigabe durch die Klinke 33 unbeabsichtigt zurückdreht.If the pressure member 39 is pressed against the force of the compression spring 42 into the body 29 via the actuating member 49, the pawl 33 is pushed in the direction of the stop 57. Since the pawl 33 is always loaded in the direction of the ratchet wheel 32 by the spring 54, it is pivoted into engagement with the ratchet wheel 32 when the pressure member is moved as soon as its stop surface 54 is released from the counter stop surface 56. This is the case before the pawl 33 comes to rest against the stop 57. The still available displacement path of the pressure member 39 or the pawl 33 is sufficient to rotate the ratchet wheel 32 and thus the spindle 30. The locking body 36 ratchets over the teeth of the ratchet wheel 32. The rotational movement of the spindle 33 is ended as soon as the pawl 33 comes to rest against the stop 57. By the distance between the stop 57 and the pawl 33 located in the stop position the rotation of the ratchet wheel 32 can be set very easily. The greater the distance between the stop 57 and the pawl 33, the more the ratchet wheel 32 can be rotated when the pressure member 39 is moved. As soon as the pressure member 39 is released, it is returned to its starting position under the force of the compression spring 42. Fig. 4 pushed back. The pawl 33 is disengaged from the ratchet wheel 32 and reaches the stop position according to FIG. Fig. 4, in which it rests with its stop surface 55 under the force of the spring 54 on the counter stop surface 56. The locking device 35 prevents the ratchet wheel 32 from unintentionally turning back after the release by the pawl 33.

Durch das Drehen des Klinkenrades 32 und damit der Spindel 30 wird ein Schlagbolzen 61 (Fig. 3) axial verschoben, der in Richtung auf den Messerkopf 17 aus dem Korpus 29 ragt. Der Schlagbolzen 61 hat ein Innengewinde 62, in das die Spindel 30 eingreift. Außerdem ist der Schlagbolzen 61 innerhalb der Aufnahme 63 des Korpus 29 gegen Drehen gesichert. Dadurch wird der Schlagbolzen 61 beim Drehen der Spindel 30 nicht drehend mitgenommen, sondern lediglich axial verstellt.By turning the ratchet wheel 32 and thus the spindle 30, a firing pin 61 (FIG. 3) is axially displaced, which projects out of the body 29 in the direction of the cutter head 17. The firing pin 61 has an internal thread 62 in which the spindle 30 engages. In addition, the firing pin 61 is secured against rotation within the receptacle 63 of the body 29. As a result, the firing pin 61 is not rotatably carried along when the spindle 30 is rotated, but is only adjusted axially.

Mit dem Schlagbolzen 61 kommt der Schwingkörper 4, wenn er gegen den Messerkopf 17 zum Profiljointen geschwenkt wird, an einem (nicht dargestellten) Gegenanschlag zur Anlage.With the firing pin 61, the oscillating body 4 comes to rest against a counter-stop (not shown) when it is pivoted against the cutter head 17 for profile joining.

Zum Profiljointen wird der Schwingkörper 4 mittels des (nicht dargestellten) Antriebes um die Achsen 7, 8 in Richtung auf den Messerkopf 17 geschwenkt. Nach dem Jointvorgang wird der Schwingkörper 4 wieder in seine Ausgangslage zurückgeschwenkt. In der Ausgangslage kommt das Betätigungsglied 40 des Druckgliedes 39 an einem weiteren (nicht dargestellten) Anschlag zur Anlage. Dieser Anschlag ist so angeordnet, daß das Druckglied 39 beim Zurückschwenken gegen die Kraft der Druckfeder 42 verschoben wird. Dabei kommt die Klinke 33 in der beschriebenen Weise in Eingriff mit dem Klinkenrad 32 und dreht dieses. Dadurch wird in der beschriebenen Weise der Schlagbolzen 61 zurückgedreht. Der Anschlag 57 ist so eingestellt, daß das Klinkenrad 32 und damit die Spindel 30 so weit gedreht werden, daß der Schlagbolzen 61 so weit zurückgezogen wird, daß beim erneuten Verschwenken des Schwenkkörpers 4 die Jointsteine 13 wieder ihre genaue Arbeitslage in bezug auf die Messer des Messerkopfes 17 einnehmen. Da die Jointsteine 13 und auch die Messer durch den Jointvorgang abgenutzt werden, wird durch die Nachstellung der Abnutzungsgrad automatisch beim Zurückschwenken des Schwenkkörpers 4 durch Nachstellen des Schlagbolzens 61 ausgeglichen. Da er beim Nachstellvorgang entsprechend dem Abnutzungsgrad zurückgezogen wird, muß der Schwingkörper 4 entsprechend dem Abnutzungsgrad einen geringfügig größeren Schwenkweg zurücklegen, um die Jointsteine 13 in ihre Arbeitslage zu bringen.For profile joining, the oscillating body 4 is pivoted about the axes 7, 8 in the direction of the cutter head 17 by means of the drive (not shown). After the jointing process, the vibrating body 4 is pivoted back into its starting position. In the starting position, the actuator 40 of the pressure member 39 comes on another (not shown) stop to the system. This stop is arranged so that the pressure member 39 is displaced against the force of the compression spring 42 when pivoting back. The pawl 33 engages and rotates the ratchet wheel 32 in the manner described. As a result, the firing pin 61 is turned back in the manner described. The stop 57 is set so that the ratchet wheel 32 and thus the spindle 30 are rotated so far that the firing pin 61 is retracted so far that when the swivel body 4 is pivoted again, the joint stones 13 return to their exact working position with respect to the knife of the Take knife head 17. Since the joint stones 13 and also the knives are worn out by the jointing process, the degree of wear is automatically compensated for by the readjustment of the swivel body 4 by readjusting the firing pin 61. Since it is withdrawn during the readjustment process in accordance with the degree of wear, the vibrating body 4 must travel a slightly larger swivel path in accordance with the degree of wear in order to bring the joint stones 13 into their working position.

In der Ausgangsstellung (Fig. 2) ist der Schwingkörper 4 hinter einer Abdeckung 64 (Fig. 2) angeordnet. Die Abdeckung 64 wird vorzugsweise durch eine Blechplatte gebildet, die um eine Achse 65 schwenkbar am Grundkörper 1 gelagert ist. Die Schwenkachse 65 befindet sich am oberen Rand der plattenförmigen Abdeckung 64, deren unterer Rand 66 spitzwinklig abgewinkelt ist. Befindet sich der Schwingkörper 4 mit den Jointsteinen 13 in seiner Ausgangsstellung, dann liegt er geschützt hinter der Abdeckung 64, deren abgewinkelter Rand 66 eine Durchtrittsöffnung 67 im Grundkörper 1 abdeckt. Dadurch kann kein Schmutz an den Schwingkörper 4, insbesondere an dessen Jointsteine 13, gelangen. Der Grundkörper 1 selbst ist zumindest gegen den Messerkopf 17 durch eine Wand 68 geschlossen, in der sich die Durchtrittsöffnung 67 befindet. Die Wand 68 ist zur Anpassung an den Flugkreis des Messerkopfes 17 gekrümmt ausgebildet (Fig. 2). Beim Verschwenken des Schwingkörpers 4 wird die Abdeckung 64 selbsttätig in eine die Durchtrittsöffnung 67 für die Jointsteine 13 freigebende Lage verschwenkt. Hierzu ist die Abdeckung 64 mit einer Seitenwand 69 versehen, die eine Steuerbahn 70 für einen am Schwingkörper 4 vorgesehenen Mitnehmer 71 aufweist. Er liegt in der Schließstellung der Abdeckung 64 an einem absatzförmigen Abschnitt der Steuerbahn 70 an (Fig. 2). Wird der Schwingkörper 4 aus der Ausgangsstellung gem. Fig. 2 in Richtung auf den Messerkopf 17 geschwenkt, dann wird die Abdeckung 64 durch den Mitnehmer 71 in Fig. 2 so weit aufwärts geschwenkt, daß der Rand 66 der Abdeckung die Durchtrittsöffnung 67 freigibt, so daß die Jointsteine 13 durch die Durchtrittsöffnung hindurchtreten können. Die Steuerbahn 70 ist so ausgebildet, daß auf jeden Fall zunächst der Abdeckungsrand 66 weggeschwenkt ist, bevor die Jointsteine 13 durch die Durchtrittsöffnung 67 heraustreten. Eine Kollison zwischen dem Rand 66 und den Jointsteinen 13 ist dadurch ausgeschlossen. Wird nach dem Jointvorgang der Schwingkörper 4 in seine Ausgangslage zurückgeschwenkt, schwenkt die Abdeckung 64 um die Achse 65 unter ihrem Eigengewicht selbsttätig wieder in die Abdeckstellung gem. Fig. 2 zurück. Zusätzlich kann auch wenigstens eine Feder vorgesehen sein, welche die Abdeckung 64 in Richtung auf ihre Schließstellung belastet, so daß sie zuverlässig in die Schließstellung zurückgeschwenkt wird. Die Jointeinrichtung ist so ausgebildet, daß selbst während des Arbeitens mit dem Messerkopf 17 der Jointvorgang vorgenommen werden kann. Der Bedienungsmann an der Holzbearbeitungsmaschine, an der die Jointeinrichtung angeordnet ist, muß lediglich den Antrieb für den Schwingkörper 4 einschalten, wodurch der Schwingkörper in Pfeilrichtung 27 in der beschriebenen Weise verschwenkt und der Jointvorgang durchgeführt wird. Wird nur eine Geradjointung durchgeführt, dann wird der Schwingkörper 4 nach dem Schwenken des Schwingkörpers mittels des Antriebes 23 achsparallel zum Messerkopf 17 verschoben. Da der Schwingkörper mehrere Jointsteine 13 aufweist, kann mit einem verhältnismäßig kleinen Hub gearbeitet werden. Dadurch kann der Schwingkörper und damit die gesamte Jointeinrichtung sehr kompakt ausgebildet sein. Zum Profiljointen wird der Schwingkörper 4 lediglich in Pfeilrichtung 27 mit Vorschubgeschwindigkeit bis auf den Profilgrund der Messer geschwenkt. Mit dem Griffstück 31 (Fig. 3) kann die Spindel 30 und damit der Schlagbolzen 61 grob eingestellt werden. Die Feineinstellung des Schlagbolzens 61 wird dann mit dem Klinkenradmechanismus 32, 33 vorgenommen.In the starting position (FIG. 2), the oscillating body 4 is arranged behind a cover 64 (FIG. 2). The cover 64 is preferably formed by a sheet metal plate which is pivotably mounted on the base body 1 about an axis 65. The pivot axis 65 is located on the upper edge of the plate-shaped cover 64, the lower edge 66 of which is angled at an acute angle. If the vibrating body 4 with the joint stones 13 is in its starting position, it is protected behind the cover 64, the angled edge 66 of which covers a passage opening 67 in the base body 1. As a result, no dirt can get to the oscillating body 4, in particular to its joint stones 13. The base body 1 itself is at least against the cutter head 17 closed by a wall 68 in which the passage opening 67 is located. The wall 68 is curved to adapt to the flight circle of the cutter head 17 (FIG. 2). When the oscillating body 4 is pivoted, the cover 64 is automatically pivoted into a position that opens the passage opening 67 for the joint stones 13. For this purpose, the cover 64 is provided with a side wall 69 which has a control track 70 for a driver 71 provided on the oscillating body 4. In the closed position of the cover 64, it bears against a shoulder-shaped section of the control track 70 (FIG. 2). If the vibrating body 4 from the initial position. Fig. 2 pivoted in the direction of the cutter head 17, then the cover 64 is pivoted upwards by the driver 71 in Fig. 2 so far that the edge 66 of the cover clears the passage opening 67 so that the joint stones 13 can pass through the passage opening . The control track 70 is designed in such a way that in any case the cover edge 66 is pivoted away before the joint stones 13 emerge through the passage opening 67. A collision between the edge 66 and the joint stones 13 is thereby ruled out. If the vibrating body 4 is pivoted back into its starting position after the jointing process, the cover 64 automatically pivots about the axis 65 under its own weight into the covering position according to FIG. Fig. 2 back. In addition, at least one spring can also be provided, which loads the cover 64 in the direction of its closed position, so that it is reliably pivoted back into the closed position. The join device is designed such that the joint process can be carried out even while working with the cutter head 17. The operator on the woodworking machine on which the join device is arranged only has to switch on the drive for the vibrating body 4, as a result of which the vibrating body pivoted in the direction of arrow 27 in the manner described and the jointing process is carried out. If only a straight joint is carried out, then the oscillating body 4 is displaced axially parallel to the cutter head 17 by means of the drive 23 after the oscillating body has been pivoted. Since the vibrating body has several joint stones 13, it is possible to work with a relatively small stroke. As a result, the oscillating body and thus the entire join device can be made very compact. For profile joining, the oscillating body 4 is only pivoted in the direction of arrow 27 at the feed rate up to the profile base of the knife. With the handle 31 (Fig. 3), the spindle 30 and thus the firing pin 61 can be roughly adjusted. The fine adjustment of the firing pin 61 is then carried out with the ratchet wheel mechanism 32, 33.
