Definitions
- transverse guides 30th let in, on which the rear wall 24 of the cross conveyor 20 the longitudinal conveyor 14 in the transverse direction 22 are moved can. In such a transverse movement of the rear wall 24 will also the clamped between the jaws 26 tree trunk 16 in the Transversely 22 pushed over the support 28 of the longitudinal conveyor 14.
- Figs. 1 and 2a is also a machining tool in Shape of a chop saw 32 shown schematically.
- the chop saw 32 includes a circular saw blade 34 which on an arm 36 at a Stand 38 is attached.
- the arm 36 is together with the Circular saw blade 34 in the direction indicated by the arrow 40 vertical direction movable on the stand 38. Let that way perform vertical cuts on the tree trunk 16 on the circumference, when the circular saw blade 34 in the vertical direction 40th is passed through the tree trunk 16.
- a control device For controlling the longitudinal conveyor 14, the cross conveyor 20, the Chop saw 32 and the hydraulic drive 48 is a control device provided, a computing unit 52 and a thereto has connected input / output unit 54.
- the arithmetic unit 52 is associated with a memory 56 in which a computer program is stored when loading into the arithmetic unit 52 the interaction of the listed components of the dicing device 10 controls.
- the working position shown in FIG. 1 corresponds to a starting position, how to do it after fixing the tree trunk 16 on the longitudinal conveyor 14 receives.
- this starting position the tree trunk 16 is still so far from the circular saw blade 34 of Chop saw 32 removes that in a method of the circular saw blade 34 in the vertical direction 40 a section in the transverse direction 22 through the tree trunk 16 is not yet possible.
- the tree trunk 16 on the longitudinal conveyor 14 in the direction of arrows 58 to the circular saw blade 34 until the tree trunk assumes a transverse position to the circular saw blade 34, the one corresponds to predetermined depth of cut. If now the circular saw blade 34 in the upper stop position shown in Fig. 2a or in the lower stop position, so can the Tree trunk 16 on the longitudinal conveyor 14 on the chop saw 32 over be guided until the desired longitudinal position is reached, where a cut with the chop saw 32 is to be attached. In this position, the longitudinal conveyor 14 is brought to a standstill and the circular saw blade 34 in the vertical direction 40 passed through the circumference of the tree trunk 16. After this Attaching this first cut can now make more cuts be attached by the longitudinal conveyor 14 to the corresponding Route is advanced and the circular saw blade 34 again in the vertical direction through the circumference of the tree trunk 16 passed becomes.
- the longitudinal conveyor 14 After attaching the last crosscut (see Fig. 4) the longitudinal conveyor 14 is back again in the direction of its starting position method (see Fig. 5).
- the band saw unit 42 is now moved in the direction of arrow 62 to the tree trunk back, and so far that in a now following passage the tree trunk 16 by the band saw blade 46 a board with the desired board thickness is separated from the tree trunk 16.
- the longitudinal conveyor 14 is back in the direction of the arrow 64 moves, previously the band saw unit 42nd slightly away from the tree trunk 16 in the direction of arrow 66 is moved (see Fig. 6) to a contact of the band saw blade 46 with the cutting edge previously produced on the tree trunk 16 to avoid.

Claims (7)
- Procédé destiné à débiter un tronc d'arbre (16), qui peut se déplacer vers l'avant et l'arrière dans une direction longitudinale (18) sur un convoyeur longitudinal (14), comportant les étapes suivantes :a) déplacement du tronc d'arbre (16) sur le convoyeur longitudinal (14) dans une direction transversale (22), perpendiculaire à la direction longitudinale (18), vers un outil d'usinage (32), jusqu'à ce que le tronc d'arbre (16) soit positionné par rapport à l'outil (32) dans une position transversale, qui correspond à une profondeur d'usinage prédéfinissable ;b) usinage du tronc d'arbre (16) à partir de sa périphérie avec l'outil d'usinage (32) ;c) sciage du tronc d'arbre (16) dans la direction longitudinale (18) en guidant le tronc d'arbre (16) en plusieurs passes dans la direction longitudinale (18) à travers une lame de scie à ruban (46) ;
- Procédé selon la revendication 1, caractérisé en ce que la lame de scie à ruban (46) avant chaque passe selon l'étape c) est déplacée dans la direction transversale (22) pour se rapprocher du tronc d'arbre (16) à une distance telle qu'une planche est sciée avec une épaisseur souhaitée dans le tronc d'arbre (16), pendant le guidage du tronc d'arbre (16) à travers la lame de scie à ruban (46).
- Procédé selon l'une des revendications 1 ou 2, caractérisé en ce que, après chaque sciage d'une planche, la lame de scie (46) est déplacée dans la direction transversale (22) pour s'écarter du tronc d'arbre (16) sur une distance telle que le tronc d'arbre (16) sur le convoyeur longitudinal (14) peut être déplacé le long de la lame de scie (46) sans entrer en contact avec la lame de scie (46).
- Procédé selon l'une des revendications précédentes, caractérisé en ce que la lame de scie à ruban (46) est dentée dans les deux directions, de telle sorte que chaque mouvement longitudinal dans l'une des deux orientations possibles constitue une passe pendant laquelle une planche est sciée.
