Abstract

A device for severing round timber includes a rotatable circular saw and a transversal feeding device feeding round timber pieces towards the saw and for feeding cut sections of the timber from the saw towards the discharge end of the device. The feeding device includes a number of rotary conveying chains arranged in groups in the feeding direction at one side of the saw and at the opposite side of the saw. The conveying chains of two groups extend in the feeding direction such that they include an acute angle with each other and diverge from one another whereby timber sections cut off by the saw tend to move away from each other and, after being cut off, do not contact the saw teeth in the area of the saw blade.

Description

Die Erfindung betrifft eine Vorrichtung zum Zerteilen von Rundholz mittels einer in einer Querfördereinrichtung angeordneten Kreissäge, wobei die Querfördereinrichtung mehrere nebeneinander umlaufende, mit Mitnehmern bestückte Förderketten aufweist.The invention relates to a device for cutting round logs by means of a circular saw arranged in a cross conveyor, the cross conveyor having a plurality of conveyor chains running side by side and equipped with carriers.

Bei derartigen Vorrichtungen wird das Rundholz beim kontinuierlichen oder intermittierenden Vorbeilauf an der Kreissäge in Rundholzabschnitte zersägt. Die an den Förderketten angebrachten Mitnehmer führen das Rundholz gegen die sich drehende Kreissäge, deren Drehrichtung so gewählt ist, daß das Rundholz durch den Eingriff der Kreissäge nach unten auf die Förderketten gedrückt und dadurch gehalten wird, während es von den Förderketten gegen die Kreissäge weiterbewegt und dabei zersägt wird.In devices of this type, the log is sawn into log sections during continuous or intermittent passage past the circular saw. The drivers attached to the conveyor chains guide the log against the rotating circular saw, the direction of rotation of which is selected so that the log is pressed down by the engagement of the circular saw onto the conveyor chains and thereby held while it is being moved by the conveyor chains against the circular saw and is sawed up.

Bei der weiteren Förderbewegung der Förderketten bewegt sich die geschnittene Fläche des Rundholzes am Kreissägeblatt entlang. An der Stelle, an der das Rundholz den Flugkreis der Kreissäge verläßt, ist die Richtung der Umfangsbewegung der Kreissäge von unten nach oben gerichtet. Wenn die geschnittene Fläche des Rundholzes in diesem Bereich in Berührung mit den Kreissägezähnen gelangt, wird das abgesägte Rundholz hochgeschleudert, was zu Unfällen, Schäden an der Maschine oder Beschädigungen des Rundholzes führen kann. Niederhalter, die das Rundholz im Bereich des Austritts aus dem Flugkreis der Kreissäge halten, würden die Förderung des Rundholzes beeinträchtigen, zumal die Niederhalter sich an die jeweils ändernde Dicke des Rundholzes anpassen müßten. Eine weitere Schwierigkeit besteht darin, daß verhältnismüßig hohe und stoßartige Belastungen auftreten können, wenn das Rundholz nach der anfänglichen Berührung im Austrittsbereich der Kreissäge angehoben und dabei verkantet und verklemmt wird.As the conveyor chains continue to move, the cut surface of the logs moves in a circle saw blade along. At the point where the log leaves the circular saw's flight circle, the direction of the circumferential movement of the circular saw is directed from bottom to top. If the cut surface of the log in this area comes into contact with the circular saw teeth, the sawn-off log is thrown up, which can lead to accidents, damage to the machine or damage to the log. Hold-downs that hold the log in the area of the exit from the circular saw's flight circle would impair the conveyance of the log, especially since the hold-downs would have to adapt to the changing thickness of the log. Another difficulty is that relatively high and shock-like loads can occur if the log is lifted after the initial contact in the exit area of the circular saw and thereby tilted and jammed.

Aufgabe der Erfindung ist es daher, eine Vorrichtung der eingangs genannten Art mit möglichst geringem konstruktivem Aufwand so zu gestalten, daß eine Berührung zwischen der Schnittfläche des Rundholzes und der Kreissäge im Bereich des Austritts aus dem Flugkreis der Kreissäge zuverlässig verhindert wird.The object of the invention is therefore to design a device of the type mentioned with the least possible design effort so that contact between the cutting surface of the log and the circular saw in the region of the exit from the flight circle of the circular saw is reliably prevented.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Förderketten derart im spitzen Winkel zur Schnittebene der Kreissäge verlaufen, daß die auf einer Seite der Schnittebene angeordneten Förderketten in Förderrichtung gesehen divergierend zu den auf der anderen Seite der Schnittebene angeordneten Förderketten verlaufen.This object is achieved in that the conveyor chains run at an acute angle to the cutting plane of the circular saw that the conveyor chains arranged on one side of the cutting plane, seen in the conveying direction, run diverging from the conveyor chains arranged on the other side of the cutting plane.

Bei der Förderbewegung entfernen sich dadurch die auf den Förderketten liegenden Rundholzabschnitte beidseitig vom Kreissägeblatt. Wenn die Rundholzabschnitte den Flugkreis der Kreissäge verlassen, befinden sich die Schnittflächen des Rundholzes beidseitig im Abstand zum Kreissägeblatt, so daß eine erneute, unerwünschte Berührung mit den Sägezähnen sicher verhindert wird.During the conveying movement, the log sections lying on the conveyor chains move away from the circular saw blade on both sides. When the log sections leave the circle of flight of the circular saw, the cut surfaces of the log are on both sides at a distance from the circular saw blade, so that renewed, undesired contact with the saw teeth is reliably prevented.

Auf Niederhalter oder sonstige zusätzliche Einrichtungen kann vollständig verzichtet werden.Hold-down devices or other additional devices can be completely dispensed with.

Der erfindungsgemäße Verlauf der Förderketten läßt sich konstruktiv sehr einfach und mit geringem Aufwand erreichen. So wird in Weiterbildung des Erfindungsgedankens vorgeschlagen, daß alle Förderketten über Kettenräder auf zwei gemeinsamen parallelen, an den beiden Enden der Querfördereinrichtung angeordneten Wellen laufen, und daß die Abstände der auf der einen Seite der Schnittebene angeordneten Kettenräder von den auf der anderen Seite der Schnittebene angeordneten Kettenrädern am Abgabeende der Querfördereinrichtung größer ist als am Aufgabeende.The course of the conveyor chains according to the invention can be achieved in a structurally very simple manner and with little effort. It is proposed in a further development of the inventive concept that all conveyor chains run over sprockets on two common parallel shafts arranged at the two ends of the transverse conveyor, and that the distances of the sprockets arranged on one side of the cutting plane from those arranged on the other side of the cutting plane Sprockets at the discharge end of the cross conveyor is larger than at the discharge end.

Es hat sich gezeigt, daß die für derartige Querfördereinrich-ungen verwendeten Gliederketten ohne Beeinträchtigung ihrer Funktion mit so viel seitlichem Spiel ausgeführt werden können, daß sie schräg unter dem erfindungsgemäß vorgesehenen spitzen Winkel auf die zugeordneten Kettenräder auflaufen bzw. von diesen ablaufen können. Somit ist es möglich, wie bei Quersördereinrichtungen bisher üblich, am Aufgabeende und am Abgabeende jeweils nur eine einzige Kettenwelle anzuordnen, die parallel zueinander verlaufen. Allein durch die Veränderung des Abständs der Kettenräder wird der erfindungsgemäß erwünschte Schräglauf der Förderketten erreicht.It has been shown that the link chains used for such transverse conveying devices can be designed with so much lateral play without impairing their function that they run obliquely onto the assigned sprockets at the acute angle provided according to the invention or can run off them. It is thus possible, as was previously the case with cross conveyor systems, to arrange only a single chain shaft at the end of delivery and at the end of delivery, that run parallel to each other. The skewing of the conveyor chains desired according to the invention is achieved solely by changing the spacing of the chain wheels.

Gemäß einer Bevorzugten Ausführung der Erfindung ist vorgesehen, daß die Förderketten auf der einen Seite der Schnittebene wie üblich senkrecht zu den Wellen verlaufen, daß die Förderketten auf der anderen Seite der Schnittebene schräg zu den Wellen verlaufen, und daß die Schnittebene der Kreissäge dazwischen angenähert in der Winkelhalbierenden liegt. Damit wird erreicht, daß nur die auf einer Seite der Schnittebene liegenden Förderketten schräg auf die Kettenräder auflaufen bzw. von diesen ablaufen. Die Schrägstellung zwischen den übrigen Förderketten und der Kreissäge wird durch eine Schrägstellung der Kreissäge erreicht.According to a preferred embodiment of the invention it is provided that the conveyor chains on one side of the cutting plane run perpendicular to the shafts as usual, that the conveyor chains on the other side of the cutting plane run obliquely to the shafts, and that the cutting plane of the circular saw between them approximates in the bisector. This ensures that only the conveyor chains lying on one side of the cutting plane run obliquely onto the chain wheels or run from them. The inclination between the other conveyor chains and the circular saw is achieved by inclining the circular saw.

Die Erfindung wird nachfolgend an einem Ausführungsbeispiel näher erläutert, das in der Zeichnung dargestellt ist. Es zeigt:

  • Fig. 1 in einem senkrechten Schnitt eine Querfördereinrichtung für Rundholz mit einer Kreissäge und
  • Fig. 2 eine vereinfachte Draufsicht auf die Querfördereinrichtung nach Fig. 1, wobei Teile weggelassen sind.
The invention is explained in more detail below using an exemplary embodiment which is illustrated in the drawing. It shows:
  • Fig. 1 in a vertical section a cross conveyor for logs with a circular saw and
  • Fig. 2 is a simplified plan view of the cross conveyor of Fig. 1, with parts omitted.

Die dargestellte Querfördereinrichtung 1 weist zwei Gruppen von endlosen umlaufenden Förderketten 2 und 3 auf, wobei von jeder Gruppe in Fig. 2 nur zwei Fürderketten 2 bzw. 3 dargestellt sind.The cross conveyor 1 shown has two groups of endless revolving conveyor chains 2 and 3, only two conveyor chains 2 and 3 of each group being shown in FIG. 2.

Die Förderketten 2, 3 laufen am Aufgabeende der Querfördereinrichtung 1 über Kettenräder 4 bzw. 5, die auf einer gemeinsamen Welle 6 sitzen. Parallel zur Welle 6 ist am Abgabeende eine Welle 7 angeordnet, die Kettenräder 8, 9 trägt, über die die Förderketten 2 bzw. 3 laufen. Eine der beiden Wellen 6, 7 wird angetrieben.The conveyor chains 2, 3 run at the feed end of the cross conveyor 1 via chain wheels 4 and 5, respectively, which are seated on a common shaft 6. A shaft 7 is arranged parallel to the shaft 6 at the discharge end and carries chain wheels 8, 9, over which the conveyor chains 2 and 3 run. One of the two shafts 6, 7 is driven.

Die Förderketten 2, 3 sind in gleichmäßigen Abständen mit Mitnehmern 10 bestückt, die am Aufgabeende aus einer Rollenförderbalm 11 jeweils ein Rundholz 12 aufnehmen und in der mit einem Pfeil 13 bezeichneten Richtung gegen eine Kreissäge 14 fördern, die zwischen den beiden Gruppen von Förderketten 2 und 3 angeordnet ist. In Fig. 2 ist ein Antriebsmotor 15 angedeutet, der die Kreissäge 14 über einen Riementrieb 16 antreibt. In Fig. 1 ist gezeigt, daß die Lagerung der Kreissäge 14 an einem mittels eines druckmittelbetätigten Zylinders 17 anhebbaren Schwenkarm 18 angebracht werden kann.The conveyor chains 2, 3 are equipped at regular intervals with drivers 10, each of which receives a round timber 12 from a roller conveyor bale 11 at the end of the feed and in the direction indicated by an arrow 13 against a circular saw 14, which between the two groups of conveyor chains 2 and 3 is arranged. A drive motor 15 is indicated in FIG. 2, which drives the circular saw 14 via a belt drive 16. In Fig. 1 it is shown that the mounting of the circular saw 14 can be attached to a swivel arm 18 which can be raised by means of a pressure-operated cylinder 17.

Die Kreissäge 114 zerteilt das Rundholz 12 in Rundholzabschnitte 12' und 12", die am Abgabeende der Querfördereinrichtung 1 auf eine Schrägfläche 19 abgeworfen und mittels einer schwenkbaren Übergabevorrichtung 20 an einen Längsförderer 21 übergeben werden, der die Rundholzabschnitte 12', 12" weiterfördert.The circular saw 1 1 4 divides the round wood 12 into round wood sections 12 'and 12 ", which are thrown onto an inclined surface 19 at the discharge end of the cross conveyor 1 and are transferred by means of a pivotable transfer device 20 to a longitudinal conveyor 21 which conveys the round wood sections 12', 12" .

Wie man aus Fig. 2 erkennt, sind die Förderketten 2 der auf der einen Seite der Schnittebene der Kreissäge 14 angeordneten Gruppe parallel zueinander und senkrecht zu den Achsen der Wellen 6, 7 angeordnet. Die Förder - ketten 3 der anderen Gruppe verlaufen dagegen in einem etwas vom rechten Winkel abweichenden stumpfen Winkel zu den Achsen der Wellen 6 und 7, d. h. die Förderketten 3 laufen schräg auf die zugeordneten Kettenräder 5 und 9 auf und von diesen ab. Die die Schnittebene bestimmende Kreissäge 14 liegt angenähert auf einer Winkelhalbierenden zwischen den beiden Gruppen von Förderketten 2 bzw. 3. Durch den zwischen den Förderketten 2 und der Schnittebene der Kreissäge 14 einerseits und den zwischen den Förderketten 3 und der Schnittebene der Kreissäge 14 andererseits jeweils gebildeten spitzen Winkel wird erreicht, daß die beiden in Förderrichtung 13 divergierenden Gruppen von Förderketten 2 bzw. 3 die abgesägten Rundholzabsclmitte 12' und 12'' auseinanderbewegt werden, so daß sich ihre Schnittflächen von der Kreissäge 14 wegbewegen. Wenn die Rundholzabschnitte 12' und 12'' aus dem Flugkreis der Kreissäge 14 austreten, befinden sich ihre Schnittflächen im Abstand zur Kreissäge 14 und berühren daher die Kreissägezähne an dieser Stelle nicht mehr.As can be seen from FIG. 2, the conveyor chains 2 of the group arranged on one side of the cutting plane of the circular saw 14 are arranged parallel to one another and perpendicular to the axes of the shafts 6, 7. Conveyor chains 3 of the other group run in one somewhat obtuse from the right angle to the axes of the shafts 6 and 7, ie the conveyor chains 3 run obliquely onto the associated chain wheels 5 and 9 and from them. The circular saw 14 determining the cutting plane lies approximately on a bisector between the two groups of conveyor chains 2 and 3, respectively. The one formed between the conveyor chains 2 and the cutting plane of the circular saw 14 on the one hand and between the conveyor chains 3 and the cutting plane of the circular saw 14 on the other hand An acute angle is achieved in that the two groups of conveyor chains 2 and 3 diverging in the conveying direction 13 and the sawn-off logs 12 'and 12''are moved apart, so that their cut surfaces move away from the circular saw 14. When the log sections 12 'and 12''emerge from the flight circle of the circular saw 14, their cutting surfaces are at a distance from the circular saw 14 and therefore no longer touch the circular saw teeth at this point.

Die Schrägstellung der Gruppen von Förderketten 2 bzw. 3 zueinander wird in einfacher Weise dadurch erreicht, daß der Abstand der Kettenräder 9 zu den Kettenrädern 8 am Abgabeende der Querfördereinrichtung 1 jeweils größer ist als der entsprechende Abstand der Kettenräder 5 von den Kettenrädern 4 am Aufgabeende.The inclination of the groups of conveyor chains 2 and 3 to each other is easily achieved in that the distance between the sprockets 9 to the sprockets 8 at the discharge end of the cross conveyor 1 is greater than the corresponding distance of the sprockets 5 from the sprockets 4 at the feed end.
