Description

Die Erfindung betrifft eine Vorrichtung zum Wenden eines Baumstammes bei dessen Bearbeitung, wie Entastung und/oder Entrindung.The invention relates to a device for turning a tree trunk during its processing, such as delimbing and / or debarking.

Baumstämme im Wald werden in der Regel entastet oder entrindet. Sobald eine Seite des Baumstammes bearbeitet ist, wird es notwendig, den Baumstamm zu drehen, um auch die andere Seite zu bearbeiten. Dieses Drehen ist insbesondere bei Baumstämmen stärkerer Stärkeklassen sehr schwierig und, wenn es von Hand durchgeführt wird, sehr kraftaufwendig.Tree trunks in the forest are usually pruned or debarked. As soon as one side of the tree trunk is processed, it becomes necessary to turn the tree trunk in order to also process the other side. This turning is very difficult, particularly with tree trunks of stronger starch classes, and, if it is carried out by hand, very energy-intensive.

Aus der Deutschen Patentschrift 24 52 481 ist beispielsweise auch eine Vorrichtung zum maschinellen Entasten und/oder Entrinden von Baumstämmen bekannt, welche mit einem Schlepper über den Baumstamm gezogen wird. Auch hier wird nach der Bearbeitung der einen Seite des Baumstamms ein Wenden des Baumstamms notwendig. Dies geschieht heute noch von Hand mit dem sogenannten Wendehaken.From the German patent specification 24 52 481, for example, a device for machine delimbing and / or debarking of tree trunks is known, which is pulled over the tree trunk with a tractor. Here, too, it is necessary to turn the tree trunk after processing one side of the tree trunk. This is still done by hand with the so-called turning hook.

Der Erfinder hat sich zum Ziel gesetzt, eine Vorrichtung der oben genannten Art zu entwickeln, welche ein Wenden des Baumstammes auf einfache Weise ohne weitere Handarbeit erlaubt.The inventor has set itself the goal of developing a device of the type mentioned above, which allows the tree trunk to be turned in a simple manner without further manual work.

Zur Lösung dieser Aufgabe führt, daß in einem Tragkasten in die gleiche Drehrichtung laufende Räder angeordnet sind, welche den Baumstamm zwischen sich aufnehmen.To solve this problem leads that running wheels are arranged in the same direction of rotation, which accommodate the trunk between them.

Erfindungsgemäß können diese Räder von Hand mittels einer Ratsche in Bewegung gesetzt werden. Bevorzugt wird jedoch ein motorischer Antrieb, welcher in einer weiterverbesserten Ausführungsform der Erfindung vom Schlepper aus ferngesteuert wird.According to the invention, these wheels can be set in motion by hand using a ratchet. However, a motorized drive is preferred, which in a further improved embodiment of the invention is remotely controlled from the tractor.

Damit die Räder den Baumstamm besser angreifen können, sollen sie umfangseitig mit Zähnen versehen sein. Weiterhin soll in den Tragkasten zwischen den Rädern eine Mulde zur Aufnahme des Baumstamms eingeformt sein. Diese Mulde kann von Baumstämmen stärkerer Stärkeklasse nicht vollständig ausgefüllt werden, dagegen drückt deren Gewicht erheblich mehr auf die Zähne, so daß ein Wenden ohne Schwierigkeit möglich ist. Baumstämme schwächerer Stärkeklasse liegen dagegen tiefer in der Mulde, so daß wiederum ein Angreifen der Zähne verbessert ist.So that the wheels can better attack the tree trunk, they should be provided with teeth on the circumference. Furthermore, a recess for receiving the tree trunk should be formed in the carrier box between the wheels. This hollow cannot be completely filled by tree trunks of a stronger strength class, but their weight presses the teeth considerably more, so that turning is possible without difficulty. Tree trunks of weaker strength class, however, lie deeper in the trough, so that attacking the teeth is improved.

Bevorzugt sollen die Räder an Wellen gelagert sein, welche von einem Motor in die gleiche Drehrichtung versetzt werden. Hierzu ist erfindungsgemäß vorgesehen, daß die Wellen über mit sich kreuzenden Keilriemen mit einer etwa mittig im Tragkasten angeordneten Antriebswelle verbunden sind und diese von beiden Seiten um-schlingen. Gegebenenfalls können zwischen Antriebswelle und Motor noch Übersetzungsgetriebe und weitere Getriebeelemente vorgesehen sein. Da die Vorrichtung ihre Anwendung vor allem im Wald finden soll, wird erfindungsgemäß als Energiequelle für den Motor eine Batterie vorgesehen. Die Steuerung des Motors selbst erfolgt über eine Fernsteuereinrichtung, wobei der Sender auf dem Schlepper sitzt.Preferably, the wheels should be mounted on shafts which ver from a motor in the same direction of rotation be set. For this purpose, it is provided according to the invention that the shafts are connected by means of intersecting V-belts to an approximately centrally arranged drive shaft and wrap them around from both sides. If necessary, transmission gears and further gear elements can be provided between the drive shaft and the motor. Since the device is to be used primarily in the forest, a battery is provided according to the invention as an energy source for the motor. The motor itself is controlled by a remote control device, with the transmitter sitting on the tractor.

Selbstverständlich können auch mehrere Räder an einer Welle angeordnet sein.Of course, several wheels can also be arranged on a shaft.

Die Erfindung soll auch ein Verfahren zum Wenden eines Baumstammes bei dessen Bearbeitung, wie Entastung und/oder Entrindung umfassen, bei dem in einem Tragkasten angeordnete Räder, welche den Baumstamm zwischen sich aufnehmen, ferngesteuert in die gleiche Drehrichtung bewegt werden.The invention is also intended to include a method for turning a tree trunk during its processing, such as delimbing and / or debarking, in which wheels arranged in a carrying case and which hold the tree trunk between them are moved in the same direction by remote control.

Weitere Vorteile, Merkmale und Einzelheiten der Erfindung ergeben sich aus der nachfolgenden Beschreibung eines bevorzugten Ausführungsbeispiels sowie anhand der Zeichnung; diese zeigt in

  • Figur 1 eine Draufsicht auf eine erfindungsgemäße Vorrichtung zum Wenden von Baumstämmen;
  • Figur 2 eine Stirnansicht der erfindungsgemäßen Vorrichtung nach Figur 1.
Further advantages, features and details of the invention result from the following description of a preferred exemplary embodiment and from the drawing; this shows in
  • Figure 1 is a plan view of an inventive device for turning tree trunks;
  • FIG. 2 shows an end view of the device according to the invention according to FIG. 1.

Eine Vorrichtung zum Wenden von Baumstämmen weist einen Tragkasten 1 auf, an welchen ein Kasten 2, insbesondere zur Aufnahme eines Antriebs und dessen Steuerung angeformt ist. Dabei besteht der Tragkasten 1 aus einer Stirnwand 3, einer Mittelwand 4 sowie einer Endwand 5. Stirnwand 3, Mittelwand 4 und Endwand 5 sind mit einer muldenförmigen Vertiefung 6 versehen, wie dies deutlicher in Figur 2 gezeigt ist. In diese muldenförmige Vertiefung 6 werden Baumstämme eingelegt, die beispielsweise entrindet werden sollen.A device for turning tree trunks has a support box 1, on which a box 2, in particular for receiving a drive and its control, is molded. The carrier box 1 consists of an end wall 3, a middle wall 4 and an end wall 5. End wall 3, middle wall 4 and end wall 5 are provided with a trough-shaped recess 6, as is shown more clearly in FIG. In this trough-shaped recess 6 tree trunks are inserted, which are to be debarked, for example.

Stirnwand 3 und Mittelwand 4 verbindet weiterhin eine Stützwand 7. Diese Stützwand 7 unterteilt zwei Fächer 8 und 9, in denen Räder 10 drehbar gelagert sind, wobei die Räder 10 umfangseitig mit Zähnen 11 versehen sind. Je vier Räder 10 lagern an einer Welle 12, welche wiederum in zwei Lagerschalen 13 und 14 dreht. Nach der Lagerschale 14 werden die Wellen 12 jeweils von Keilriemen 15 und 16 angegriffen, welche beispielsweise aus Antriebsketten bestehen können. Beide Keilriemen umfangen eine etwa mittig angeordnete Antriebswelle 17, so daß durch diese Anordnung die Drehung der Räder 10 in die gleiche Drehrichtung bewirkt wird. Die Drehung der Antriebswelle 17 übernimmt ein weiterer Riemen 18, welcher ebenfalls als Kette ausgebildet sein kann. Dieser Riemen 18 umschlingt andererseits von der Antriebswelle 17 eine Getriebewelle 19, welche durch die Endwand 5 hindurch in ein Übersetzungsgetriebe 20 einragt und hier mit einem Motor 21 in Verbindung steht. Der Motor 21 wird von einer Batterie 22 gespeist. Die Steuerung des Motors, das heißt insbesondere sein Vor- oder Rücklauf, erfolgt durch eine Fernsteuereinrichtung 23.End wall 3 and middle wall 4 also connect a support wall 7. This support wall 7 divides two compartments 8 and 9, in which wheels 10 are rotatably mounted, the wheels 10 being provided with teeth 11 on the circumference. Four wheels 10 each are mounted on a shaft 12, which in turn rotates in two bearing shells 13 and 14. After the bearing shell 14, the shafts 12 are each attacked by V-belts 15 and 16, which can consist, for example, of drive chains. Both V-belts surround an approximately centrally arranged drive shaft 17, so that this arrangement causes the wheels 10 to rotate in the same direction of rotation. The rotation of the drive shaft 17 is carried out by a further belt 18, which can also be designed as a chain. This Belt 18, on the other hand, wraps around a drive shaft 17 from the drive shaft 17, which projects through the end wall 5 into a transmission gear 20 and is connected here to a motor 21. The motor 21 is powered by a battery 22. The control of the motor, that is to say, in particular its forward or reverse, is carried out by a remote control device 23.

Zum Entasten und Entrinden eines Baumstammes mittels einer Vorrichtung, wie sie beispielsweise in dem Deutschen Patent 24 52 481 gezeigt ist, wird ein Baumstamm in die Mulde 6 eingelegt. Nun kann diese eben genannte Entastungs- und Entrindungsvorrichtung über den Baumstamm gezogen werden.,Hierdurch wird die Oberfläche des Baumstamms entastet und entrindet. Nach diesem Vorgang kann ferngesteuert vom Schlepper aus der Motor 21 in Bewegung gesetzt und die Räder 10 über die entsprechende Anordnung von Keilriemen 15, 16, Antriebswelle 17, Riemen 18, Getriebewelle 19 und Getriebe 20 in Drehbewegung versetzt werden. Hierdurch erfolgt ein Wenden des Stammes, so daß die noch nicht entastete bzw. entrindete Seite des Baumstamms nach oben kommt und nunmehr mit der Vorrichtung bearbeitet werden kann.For delimbing and debarking a tree trunk using a device such as that shown in German Patent 24 52 481, a tree trunk is placed in the recess 6. Now this delimbing and debarking device just mentioned can be pulled over the tree trunk. This will delimb and debark the surface of the tree trunk. After this process, the motor 21 can be remotely controlled by the tractor and the wheels 10 can be rotated via the corresponding arrangement of V-belts 15, 16, drive shaft 17, belt 18, transmission shaft 19 and transmission 20. This causes the trunk to be turned so that the side of the tree trunk that has not yet been delimbed or debarked comes up and can now be processed with the device.
