Die Erfindung betrifft eine Vorrichtung zum span losen Querschneiden von Rundholz, bestehend aus einem gegenüber einem als Gegenhalter wirkenden Amboß senkrecht zur Holzlängsachse verschwenkba· ren Trennmesser mit einem vorzugsweise hydraulischen Antrieb, aus einer mit der Schneideinrichtung fluchtenden Transporteinrichtung für das Rundholz und aus einem das Rundholz auf zumindest zwei sich gegenüberliegenden Seiten mit je einem Schenkel amgreifenden Gestell, das um eine parallel zur Drehachse des Trennmessers angeordnete Achse verschwenkbar gelagert ist und das zwischen den beiden Schenkeln verschwenkbare Trennmesser trägt, dess=:i Antrieb an dem einen Schenkel befestigt ist, während der andere Schenkel auf seiner Innenseite den Amboß trägt, der mit seiner Oberfläche unter die Transponebene der Transporteinrichtung verschwenkbar ist, nach Patent 2 149 805.The invention relates to a device for span loose cross-cutting of round timber, consisting of one opposite one acting as a counter-holder Anvil swiveling perpendicular to the longitudinal axis of the wood with a cutting knife, preferably a hydraulic one Drive from a transport device for the logs that is aligned with the cutting device and from one the round wood on at least two opposite sides with one leg each engaging Frame which can be pivoted about an axis arranged parallel to the axis of rotation of the cutting knife is mounted and carries the separating knife pivotable between the two legs, dess =: i Drive is attached to one leg, while the other leg on its inside is the anvil carries, which can be pivoted with its surface below the transpon plane of the transport device, according to patent 2,149,805.
Bei dieser Ausführungsform bildet das schwenkbare Trenr.messer das einzige Schneidelement. Die Oberfläche des Ambosses dient während des Querschnitts als Holzauflagefläche.In this embodiment, the pivotable cutting knife forms the only cutting element. the The surface of the anvil serves as a wooden support surface during the cross-section.
Der Erfindung liegt die Aufgabe zugrunde, die vorstehend beschriebene Vorrichtung dahingehend zu verbessern, daß eine höhere Schnittleistung bei sauberer Schnittfläche erzielt wird. The invention is based on the object of improving the device described above in such a way that a higher cutting performance is achieved with a clean cut surface.
Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß der Amboß als Gegenmesser ausgebildet ist, das zweckmäßig sichelförmig gestaltet sein kann.This object is achieved according to the invention in that the anvil is designed as a counter knife is, which can be designed appropriately sickle-shaped.
In der Zeichnung ist eine als Beispiel dienende Ausführungsform der Erfindung in schematischer Stirnansicht dargestellt.An exemplary embodiment of the invention is shown schematically in the drawing Front view shown.
Auf einem durch Konus-Transportrollen 2 gebildeten Längsförderer wird das Rundholz in den Arbeitsbereich einer Vorrichtung zum spanlosen Querschneiden gefördert. Letztere besteht aus einem im Querschnitt angenähert U-förmig ausgebildeten Gestell 9, das an seinem U-Steg um eine parallel zur Längsrichtung des Rundholzes angeordnete Achse 10 verschwenkbar gelagert ist, und dessen U-Schen- kel das aufzuteilende Rundholz unter- bzw. übergreifen. Zwischen den beiden U-Schenkeln ist ein verschwenkbares Trennmesser 3 vorgesehen, das an seinem einen Ende an dem U-Steg des Gestells 9 über eine parallel zur Achse 10 angeordnete Drehachse 4 angelenkt ist. Der Antrieb 6 des Trennmessers 3 besteht aus einem Arbeitszylinder, der bei 8 an dem Ende des einen U-Schenkels angelenkt ist, und dessen Kolbenstange bei 7 an dem Trennmesser angi^,:i. On a longitudinal conveyor formed by conical transport rollers 2, the round wood is conveyed into the work area of a device for chipless cross-cutting. The latter consists of a cross-section approximately U-shaped frame 9, which is pivotably mounted on its U-web about an axis 10 arranged parallel to the longitudinal direction of the log, and whose U-legs reach under or over the log to be divided. A pivotable cutting knife 3 is provided between the two U-legs , which is articulated at one end to the U-web of the frame 9 via an axis of rotation 4 arranged parallel to the axis 10. The drive 6 of the cutting knife 3 consists of a working cylinder which is articulated at 8 on the end of one U-leg, and its piston rod at 7 on the cutting knife angi ^ ,: i.
Der andere Ü-Schenkel trägt auf seiner Innenseite ein als Arr.boß dienendes Gegenmesser5 und wird von einem Arbeitszylinder 13 beaufschlagt.The inside of the other U-leg has a counter knife5 serving as an arr.boß and is acted upon by a working cylinder 13.
Die neue Vorrichtung arbeitet wie folgt: \ }.,■-■, schwenkbare Trennmesser 3 sowie das Gegenm<: -■-ser5 des unteren U-Schenkels des Gestells9 \virK::i wie eine Schere zusammen. In Arbeitsauseangs-'.·■-lung ist diese Schere vollständig geöffnet. Dabei lsi das Gestell 9 so weit nach unten gegen einen ni'-iiL dargestellten Anschlag geschwenkt, daß die Schmvikante des Gegenmesseis,5 unterhalb der durch <\\: Konus-Transportrollen2 gebildeten Transported; liegt, so daß das Stammholz ungehindert in Liin.., richtung bis zu der gewünschten Lage gefördert v.. den kann. Ist diese erreicht, wird das Trennnie- ; über seinen Antrieb 6 in Pfeilrichtung 11 so v-dt nach unten geschwenkt, bis es auf dem Holzsi ;.rr■■■:■, aufliegt. Im Bereich dieses Leerlaufes kann ein Zugang angewendet werden, z.B. durch Speisung ei.-Antriebs 6 aus einem Niederdruck-Akku oder einer Niederdruck-Pumpe hoher Förderleitung. Solx'ki das Trennmesser 3 auf dem Stamm aufliegt, wird unter der Druckkraft des Antriebs 6 des Gestells 9 in Pfeilrichtung 11 so weit nach oben verschwenkt, bis das Gegenmesser 5 am Stamm anliegt. Spätestens jetzt wird der Antrieb 6 mit Hochdruck gespeist; lins Tre-inmesser 3 und das Gegenmesser 5 dringen in den Stamm ein und trennen die gewünschte Länuc ab. Anschließend schwenkt dann das Gestell 9 in seine untere Stellung ein, wobei das Trennmesser 3 im Sinne der öffnung der Schere nach oben gezogen wird. Der Reststamm und das abgetrennte Holzstück legen sich auf den Längsförderer ab. Nach dem entsprechenden Vorschub des Holzes setzt der Trennvorgang erneut ein.The new device works as follows: \}., ■ - ■, swiveling cutting knife 3 and the Gegenm <: - ■ -ser5 of the lower U-leg of the frame9 \ virK :: i like a pair of scissors. During work breaks, these scissors are fully open. The frame 9 is swiveled so far down against a stop shown below that the narrow edge of the counter mess, 5 below the transported formed by <\\: cone transport rollers2; so that the logs can be conveyed unhindered in the direction of the line to the desired location. If this is reached, the separation knee; about its drive 6 in the direction of arrow 11 so v-dt swiveled down until it rests on the Holzsi; .rr ■■■: ■. In the area of this idling, an access can be used, for example by feeding a drive 6 from a low-pressure battery or a low-pressure pump with a high delivery line. Solx'ki the cutting knife 3 rests on the trunk, is pivoted under the pressure of the drive 6 of the frame 9 in the direction of arrow 11 so far upwards until the counter knife 5 rests on the trunk. Now, at the latest, the drive 6 is fed with high pressure; Lin's truss knife 3 and counter knife 5 penetrate the trunk and cut off the desired length. The frame 9 then swivels into its lower position, the cutting knife 3 being pulled upwards in the direction of the opening of the scissors. The remaining trunk and the separated piece of wood are deposited on the longitudinal conveyor. After the appropriate advance of the wood, the cutting process starts again.
Der Arbeitszylinder 13 dient zum Ausgleich des auf den Stamm wirkenden Gewichtes der Vorrichtunesteile3,6 und 9, damit auch bei dünneren krummen Hölzern keinerlei Biegekräfte auf den Stamm ausgeübt und somit Klemmkräfte auf das Messer ausgeschlossen werden können. Nach Beendigung eines Trennschnittes wird der Arbeitszylinder 13 auf Rückzug oder drucklos geschaltet. Mit Einsetzen der Schließbewegung des Trennmessers übt er unter Wirkung eines hydraulischen Druckes seine Funktion des Gewichtsausgleiches aus. The working cylinder 13 serves to compensate for the weight of the device parts 3, 6 and 9 acting on the trunk, so that no bending forces are exerted on the trunk even with thinner, crooked pieces of wood and thus clamping forces on the knife can be excluded. After completion of a severing cut, the working cylinder 13 is switched to retraction or depressurized. With the onset of the closing movement of the cutting knife, it exercises its weight compensation function under the effect of hydraulic pressure.
