Description

Die Erfindung betrifft eine Vorrichtung zur spanabhebenden Bearbeitung von Hölzern, insbesondere Balken oder Brettern, nach dem Oberbegriff des Patentanspruchs 1.The invention relates to a device for machining wood, in particular beams or boards, according to the preamble of patent claim 1.

Eine derartige Vorrichtung ist nach US-A-3 630 245 bereits bekannt. Dort ist die Zylindersäge auf dem Maschinengestell in Böcken mit Gleitlagern gelagert und ausserdem in einem Spannfutter gehalten. Nachteilig hierbei war es, dass die 'Zylindersäge nur schwer ausgewechselt werden konnte.Such a device is already known from US-A-3 630 245. There the cylinder saw is mounted on the machine frame in trestles with plain bearings and is also held in a chuck. The disadvantage here was that the cylinder saw was difficult to replace.

Aufgabe der Erfindung ist es, eine Vorrichtung zur spanabhebenden Bearbeitung von Hölzern der eingangs genannten Art so zu gestalten, dass bei stabiler, erschütterungsfreier Lagerung der Zylindersäge diese einfach ausgewechselt werden kann.The object of the invention is to design a device for machining wood of the type mentioned in such a way that the cylinder saw can be easily replaced with stable, vibration-free mounting.

Zur Lösung der gestellten Aufgabe sieht die Erfindung vor, dass dem Umschlingungsbereich des Riemens gegenüberliegend in Längsrichtung zwei hintereinander angeordnete Tragrollen vorgesehen sind und dass seitlich an der Zylindersäge im Bereich der Mittelachse einander gegenüberliegende Führungsrollen vorgesehen sind, die in Längsrichtung paarweise hintereinander liegen.To achieve the object, the invention provides that two looping rollers arranged one behind the other are provided in the longitudinal direction opposite the looping region of the belt and that opposite guide rollers are provided on the side of the cylinder saw in the region of the central axis, which are arranged in pairs in the longitudinal direction.

Durch diese Lagerung wird eine Vielzahl von Lagerstellen vermieden. Die Zylindersäge liegt nur auf zwei in Längsrichtung hintereinander liegenden Tragrollen auf. Die seitlich anliegenden Führungsrollen haben nur eine Führungsfunktion. Insoweit kann die Zylindersäge leicht ausgewechselt werden und es wird ein weitgehend erschütterungsfreier Lauf erreicht, da weitere, die Zylindersäge einspannende, Lagerstellen fehlen. Insoweit wird vermieden, dass Erschütterungen oder Verformungen der Zylindersäge, die von einer Lagerstelle ausgehen könnten, sich auf eine weitere Lagerstelle übertragen.This storage avoids a large number of bearing points. The cylinder saw only rests on two support rollers lying one behind the other in the longitudinal direction. The side guide rollers only have a leadership function. In this respect, the cylinder saw can be easily replaced and a largely vibration-free run is achieved since there are no further bearing points that clamp the cylinder saw. In this respect, it is avoided that vibrations or deformations of the cylinder saw, which could originate from one bearing point, are transmitted to another bearing point.

In Ausgestaltung der Erfindung ist es vorgesehen, dass die Antriebsscheibe des Riemens unterhalb der Tragrollen angeordnet ist, und mit der Längsmittenachse der Zylindersäge fluchtet. Hierdurch wird die Zylindersäge vom Antriebsriemen umschlungen und symmetrisch auf den Tragrollen gehalten, wobei durch den dämpfenden Einfluss des Riemens etwaige Erschütterungen zusätzlich abgefangen werden.In an embodiment of the invention, it is provided that the drive pulley of the belt is arranged below the support rollers and is aligned with the longitudinal center axis of the cylinder saw. As a result, the cylinder saw is wrapped around the drive belt and held symmetrically on the idlers, with the shock-absorbing influence of the belt additionally absorbing any vibrations.

Vorteilhaft können die Angriffspunkte der Führungsrollen an der Zylindersäge gegenüber den Tragrollen um 90° versetzt angeordnet sein. Hierdurch wird in einfacher konstruktiver Ausführung ein Abkippen oder Anschwingen der Zylindersäge vermieden, da etwaige Auslenkungen der Zylindersäge dort im Bereich der grössten Auslenkung von den Führungsrollen abgefangen werden.The points of engagement of the guide rollers on the cylinder saw can advantageously be arranged offset by 90 ° with respect to the support rollers. In a simple design, this prevents the cylinder saw from tipping or swinging, since any deflections of the cylinder saw are intercepted there by the guide rollers in the region of the greatest deflection.

In einer Weiterbildung der Erfindung kann eine zusätzliche Verzahnung am Auslaufende der Zylindersäge vorgesehen sein, die mit ihrem Aussendurchmesser den Aussendurchmesser der einlaufseitig angeordneten Verzahnung überragt. Hierdurch kann eine zweifache Bearbeitung des zu sägenden Holzbalkens vorgenommen werden. Einlaufseitig wird der Holzbalken zunächst grob zurecht gesägt, während die an der Auslaufseite der gleichen Zylindersäge angeordnete Verzahnung den so zurecht gerichteten Holzbalken noch weiter spanabhebend bearbeitet, z.B. schlichtet, fräst, mit Riefen versieht oder dergleichen.In a development of the invention, an additional toothing can be provided at the outlet end of the cylinder saw, the outer diameter of which projects beyond the outer diameter of the toothing arranged on the inlet side. In this way, double processing of the wooden beam to be sawn can be carried out. On the inlet side, the wooden beam is first roughly sawn into shape, while the toothing arranged on the outlet side of the same cylinder saw processes the wooden beam, which has been adjusted in this way, even further, e.g. finishing, milling, grooving or the like.

Weiterhin kann vorteilhaft am Auslaufende der Zylindersäge eine Hobelvorrichtung angeordnet werden, die dem gesägten Profil des Holzbalkens angepasste, angetriebene Profilhobelwellen aufweist. Hierdurch kann ein durch die Zylindersäge vorgesägtes Profil in der nachgeschalteten Hobeleinrichtung von der gleichen Zufuhreinrichtung aus in einfacher Weise weiter profiliert werden.Furthermore, a planing device can advantageously be arranged at the outlet end of the cylinder saw, which has driven profile planer shafts adapted to the sawn profile of the wooden beam. As a result, a profile pre-sawn by the cylinder saw can be further profiled in a simple manner in the downstream planing device from the same feed device.

Das weitere Patentbegehren ergibt sich aus den weiteren Unteransprüchen.The further patent request results from the further subclaims.

Im folgenden wird die Erfindung anhand einer lediglich einen Ausführungsweg darstellenden Zeichnung näher erläutert.

In Figur 1 und 2 ist lediglich die Lagerung einer einzigen Zylindersäge 6 an einem Maschinengestell 1 gezeichnet. Die zugeordneten Zuführtische, Auslauftische, Führungselemente und Niederhalter sind der Einfachheit halber fortgelassen. Die dementsprechenden Konstruktionselemente sind bekannt und beispielsweise aus der AT-PS 286 602 zu entnehmen. Auch ist es möglich, in Durchlaufrichtung gesehen, mehrere Zylindersägen 6 hintereinanderliegend anzuordnen, wobei jede Zylindersäge 6 dann entsprechend dem Vorschlag nach Figur 1 und 2 gelagert ist.In Figures 1 and 2, only the storage of a single cylinder saw 6 on a machine frame 1 is drawn. The assigned feed tables, outlet tables, guide elements and hold-down devices have been omitted for the sake of simplicity. The corresponding construction elements are known and can be found, for example, in AT-PS 286 602. It is also possible, viewed in the direction of passage, to arrange a plurality of cylinder saws 6 one behind the other, each cylinder saw 6 then being mounted in accordance with the proposal according to FIGS. 1 and 2.

Die Zylindersäge 6 ist in einer halbrundförmigen Ausnehmung 5 in dem Maschinengestell 1 gelagert. Am Aussenumfang der Zylindersäge 6 liegen gleichmässig radial verteilt drei Rollen an. Zur seitlichen Führung in horizontaler Ebene sind die Führungsrollen 3, vorgesehen, während eine untere Tragrolle 2 die Zylindersäge 6 in vertikaler Richtung trägt und den Zug auffängt, der von dem über den Aussenumfang der Zylindersäge 6 geschlungenen Riemen 9 ausgeübt wird.The cylinder saw 6 is mounted in a semicircular recess 5 in the machine frame 1. On the outer circumference of the cylinder saw 6 there are three rollers that are evenly distributed radially. For lateral guidance in the horizontal plane, the guide rollers 3 are provided, while a lower support roller 2 carries the cylinder saw 6 in the vertical direction and absorbs the tension which is exerted by the belt 9 looped over the outer circumference of the cylinder saw 6.

Der zu verarbeitende Holzbalken 8 wird auf den - lediglich schematisch angedeuteten - Zuführtisch 17 aufgelegt, und in Pfeilrichtung 12 (vergleiche Figur 2) der stirnseitig angeordneten Verzahnung 7 der Zylindersäge 6 zugeführt. Wesentlich hierbei ist, dass die durch den Zuführtisch 17 definierte Auflageebene 18 unterhalb der Verzahnung 7 der Zylindersäge 6 liegt, damit das stirnseitige Profil des zu verarbeitenden Holzbalkens 8 voll von der Verzahnung 7 erfasst wird. Im Bereich des Zuführtisches 17 können noch weitere Tragrollen 11 vorgesehen sein, um ein leichtes Zuführen des Holzbalkens 8 zu der Verzahnung 7 der Zylindersäge 6 zu ermöglichen. Ebenso sind noch seitliche Führungsrollen 13, 14 vorgesehen, die den Holzbalken 8 seitlich führen und sich kraftschlüssig an dessen Seitenkanten anlegen.The wooden beam 8 to be processed is placed on the - only schematically indicated - feed table 17 and fed in the direction of arrow 12 (see FIG. 2) to the toothing 7 of the cylinder saw 6 arranged at the end. It is essential here that the support plane 18 defined by the feed table 17 lies below the toothing 7 of the cylinder saw 6, so that the end profile of the wooden beam 8 to be processed is fully gripped by the toothing 7. In the area of the feed table 17, further support rollers 11 can be provided in order to easily feed the To allow wooden beam 8 to the teeth 7 of the cylinder saw 6. Likewise, lateral guide rollers 13, 14 are also provided, which guide the wooden beam 8 laterally and engage non-positively on the side edges thereof.

Die Trag- und Führungsrollen 2, 3, 4 sind gemäss der Darstellung in Figur 2 in axialer Richtung paarweise hintereinanderliegend angeordnet, um eine Verkantung der Zylindersäge 6 in axialer Richtung zu vermeiden. Am Aussenumfang der Zylindersäge 6 sind hintereinanderliegend radiale Nuten 15, 16 vorgesehen. In die Nut 16 greift der Riemen 9 ein, während in die Nuten 15 die Trag- und Führungsrollen 2, 3, 4 eingreifen. Auf diese Weise erfolgt eine axiale Verschiebungssicherung der Zylindersäge 6 am Maschinengestell 1.According to the illustration in FIG. 2, the carrying and guide rollers 2, 3, 4 are arranged in pairs one behind the other in the axial direction in order to avoid tilting of the cylinder saw 6 in the axial direction. Radial grooves 15, 16 are provided one behind the other on the outer circumference of the cylinder saw 6. The belt 9 engages in the groove 16, while the support and guide rollers 2, 3, 4 engage in the grooves 15. In this way, the cylinder saw 6 is axially secured against displacement on the machine frame 1.

Die Längsmittenachse 19 der Zylindersäge 6 fluchtet damit mit der Achse der Tragrolle 2 und diese wiederum mit der Achse der nicht näher dargestellten Antriebsscheibe für den Riemen 9.The longitudinal center axis 19 of the cylinder saw 6 is thus aligned with the axis of the support roller 2 and this in turn with the axis of the drive pulley (not shown) for the belt 9.

Es ist ferner vorgesehen, dass das gesamte Maschinengestell 1 in bezug zu dem Zuführtisch 17 in den Pfeilrichtungen 10, 10' vertikal verstellbar ist. Ebenso ist es möglich, den Zuführtisch 17 selbst in diesen Pfeilrichtungen zu verstellen.It is further provided that the entire machine frame 1 is vertically adjustable in the arrow directions 10, 10 'with respect to the feed table 17. It is also possible to adjust the feed table 17 itself in these arrow directions.

Eine andere, nicht zeichnerisch dargestellte Ausführungsform sieht vor, dass die Achsen der Trag- und Führungsrollen 2, 3, 4 selbst noch in horizontaler und vertikaler Richtung einstellbar sind, damit Zylindersägen 6 unterschiedlichen Durchmessers verwendet werden können.Another embodiment, not shown in the drawing, provides that the axes of the carrying and guide rollers 2, 3, 4 themselves can still be adjusted in the horizontal and vertical directions, so that cylinder saws 6 of different diameters can be used.

Die Auswechslung der Zylindersäge 6 erfolgt besonders einfach, weil lediglich der Riemen 9 abgenommen werden kann, während dies bei den Anordnungen des Standes der Technik sehr schwierig nur gelang, weil das im Innenprofil der Zylindersäge angeordnete Führungsstück entfernt werden musste, oder die Zylindersäge axial herausgezogen werden musste, wobei die in Durchlaufrichtung vorne und hinten liegenden Konstruktionsteile des Maschinengestells abgebaut werden mussten.The replacement of the cylinder saw 6 is particularly simple because only the belt 9 can be removed, while this was very difficult in the arrangements of the prior art only because the guide piece arranged in the inner profile of the cylinder saw had to be removed or the cylinder saw was pulled out axially had to be removed, whereby the construction parts of the machine frame lying at the front and rear in the direction of flow had to be dismantled.

Die Figuren 3 und 4 zeigen schematisiert eine hinter der Zylindersäge 6 angeordnete Hobelvorrichtung, die gemäss dem Ausführungsbeispiel aus vier gleichmässig radial am Umfang verteilten Profilhobelwellen 20, 21, 22, 23 besteht. Jede Profilhobelwelle 20 bis 23 weist ein Viertelrundes-Profil auf, so dass in dem gezeigten Ausführungsbeispiel das ausgesägte Vollrund-Profil des Holzbalkens 8 noch weiter im Sinne einer Durchmesser-Verkleinerung bearbeitet werden kann. Die Achsen der Profil-Hobelwellen 20 bis 23 sind einzeln in bezug zur Längsmittenachse 25 des Holzbalkens 8 zustellbar, so dass es möglich ist, nur eine, zwei, drei oder vier der Profilhobelwellen 20 bis 23 zum Einsatz zu bringen. Jede Profilhobelwelle weist mindestens zwei gegenüberliegende Hobelmesser 24 auf, mit denen die spanabhebende Bearbeitung vorgenommen wird.FIGS. 3 and 4 schematically show a planing device arranged behind the cylinder saw 6, which according to the exemplary embodiment consists of four profile planer shafts 20, 21, 22, 23 distributed evenly radially on the circumference. Each profile planer shaft 20 to 23 has a quarter-round profile, so that in the exemplary embodiment shown, the sawn-out full-round profile of the wooden beam 8 can be processed further in the sense of a reduction in diameter. The axes of the profile planer shafts 20 to 23 can be adjusted individually with respect to the longitudinal center axis 25 of the wooden beam 8, so that it is possible to use only one, two, three or four of the profile planer shafts 20 to 23. Each profile planer shaft has at least two opposing planing knives 24 with which the machining is carried out.

Die Profilhobelwellen 20 bis 23 können wahlweise einzeln oder auch paarweise angetrieben sein. Der Antrieb erfolgt ebenfalls über Antriebsscheiben und Antriebsriemen oder auch über andere bekannte Antriebe, wie z. B. Getriebe oder dergleichen.The profile planer shafts 20 to 23 can be driven either individually or in pairs. The drive is also via drive pulleys and drive belts or other known drives, such as. B. gear or the like.

Figur 4 zeigt, dass die obere Profil-Hobelwelle 20 in Durchlaufrichtung (Pfeilrichtung 12) hinter den seitlichen Profilhobelwellen 21, 23 nachgeordnet ist.FIG. 4 shows that the upper profile planer shaft 20 is arranged downstream of the lateral profile planer shafts 21, 23 in the direction of travel (arrow direction 12).

Die Figuren 5 bis 10 zeigen verschiedene Profilformen, wie sie mit einer Vorrichtung nach der Erfindung hergestellt werden können, nämlich durch eine Hintereinanderschaltung einer Zylindersäge nach den Figuren 1 und 2 sowie einer Hobelvorrichtung nach den Figuren 3 und 4.FIGS. 5 to 10 show different profile shapes as can be produced with a device according to the invention, namely by connecting a cylinder saw according to FIGS. 1 and 2 in series and a planing device according to FIGS. 3 and 4.

In Figur 5 ist gezeigt, wie die Holzwand eines Blockhauses aus zwei Profilen 30 erstellt werden kann. Jedes Profil 30 besteht aus einer glatten Innenseite und einer gewölbten Aussenseite, wobei die Verbindung der beiden Profile 30 durch dazwischen angeordnete Passfedern 32 und eine Dichtung 31 erfolgt.FIG. 5 shows how the wooden wall of a log house can be created from two profiles 30. Each profile 30 consists of a smooth inside and a curved outside, the connection of the two profiles 30 being made by keys 32 and a seal 31 arranged therebetween.

Die Figuren 6 und 7 zeigen Decken- oder Wandverkleidungen mit ebenfalls allseitig bearbeiteten Profilen 33, 34 bzw. 37, 39. Die Profile 33, 34 sind entweder durch eine Falzverbindung 35 oder durch eine Nut-Federverbindung 36 verbunden. Das Profil 33 besteht aus einer ebenen Innenseite und einer konkav (einwärts) gewölbten Aussenseite. Das Profil 34 ist im Gegensatz hierzu konvex gewölbt.Figures 6 and 7 show ceiling or wall cladding with profiles 33, 34 and 37, 39 also machined on all sides. The profiles 33, 34 are connected either by a rebate connection 35 or by a tongue and groove connection 36. The profile 33 consists of a flat inside and a concave (inward) curved outside. In contrast, the profile 34 is convexly curved.

Die in Figur 7 gezeigten Profilformen 37, 39, 40 zeigen ähnliche Formgebungen; sie sind aus gleichartigen Profilformen erstellt und jeweils durch Falzverbindungen 38, 41 miteinander verbunden.The profile shapes 37, 39, 40 shown in FIG. 7 show similar shapes; they are created from identical profile shapes and are connected to each other by fold connections 38, 41.

Die Figuren 8 bis 10 zeigen Vollrund-Profile mit daran angearbeiteten Verbindungen 43, 45, 47. Das Rund-Profil 42 nach Figur 8 ist zur Erstellung von Blockhäusern gedacht, ebenso wie das Oval-Profil 44 nach Figur 9 oder das im Durchmesser kleinere Rund-Profil 46 nach Figur 10. Wegen der Erstellung von Blockhäusern können auch Palisadenwände oder dergleichen mit solchen Rundprofilen 42, 44, 46 erstellt werden. Mit den Zahlen 31, 43, 47 sind Dichtungen bezeichnet.FIGS. 8 to 10 show full-round profiles with connections 43, 45, 47 worked on them. The round profile 42 according to FIG. 8 is intended for the construction of log houses, just like the oval profile 44 according to FIG. 9 or the rounder with a smaller diameter Profile 46 according to FIG. 10. Because of the construction of log houses, palisade walls or the like can also be created with such round profiles 42, 44, 46. The numbers 31, 43, 47 are seals.
