Definitions
- the invention relates to a device for cutting logs or Tree trunk parts in one cut with several non-parallel cutting planes, in particular in a quarter cut, and a sawing station for use in such a device.
- a pattern that is particularly advantageous with regard to the location of the annual rings is the So-called district section, the section of which is shown in Fig. 1.
- the tree trunk is first quartered and then cut by the alternately cut planks on both straight surfaces of the tree trunk quarter.
- the Numbers on the respective cutting lines in FIG. 1 indicate the sequence of the cuts.
- a sawing station and a corresponding device for Disassembly of logs to provide a neighborhood cut and allow related patterns to be carried out more efficiently.
- This task will according to the invention by a sawing station according to claim 1 or a device for Disassembling tree trunks or tree trunk parts according to claim 15 solved.
- Beneficial Embodiments are specified in the subclaims.
- the invention proposes for the first time, in one Saw station to use circular saws whose cutting planes, i.e. the planes of the saw blades, include a non-vanishing angle, preferably an angle of 90 °, which enables a district cut.
- the circular saws are arranged so that the in the Connect the logs produced to each other so that the sawing station in the Tree trunk can be processed simultaneously on two adjacent sides and when passing through the sawing station, there are at least two planks that are from different sides of the tree trunk.
- the circular saws are short for this arranged one after the other, so that on the one hand both saws simultaneously the tree trunk part can edit and on the other hand the saw blades of the two circular saws have a sufficient safety distance so that they do not come into contact with each other.
- the two circular saws are each equipped with several saw blades, so that tree quarters with a smaller width in one single sawing can be disassembled in a quarter cut.
- the saw blades have a different diameter, which corresponds to the decreasing plank width corresponds to the quarter cut (referring to FIG. 1, for example, the planks, which are created with the cuts 1 to 4, much wider than those cuts that with the cuts 14 to 19 are generated).
- These are preferably concentric several saw blades spaced from each other and according to the intended screed thickness arranged, the diameter of which in the direction away from a stop for the tree part decreases.
- a hollow shaft arrangement is preferred in which at least some of the saw blades is arranged on hollow shafts that receive another shaft in their interior.
- the different shafts can be moved against each other so that the distance between the saw blades and thus also the cutting thickness can be changed.
- Separate Saw blades can be exchangeable to allow different cutting thicknesses.
- one or more hollow shafts in a hollow shaft receiving them is limited in a plane perpendicular to the shaft axis are displaceable by the distance of the edges of the saw blades in the plane perpendicular to To be able to adapt the shaft axis to a changed screed thickness during a quarter cut.
- each shaft that can be moved transversely to the axial direction has its own relocatable shaft Has drive or, which is preferred, via a gear with a common drive connected, which allows the shafts to be displaced perpendicular to the axial direction, for example a worm gear, a gear with a telescopic rod or a variable-length converter cylinder or the like.
- a movable stop can be provided.
- the shaft arrangement a circular saw overall out of and into the machining area can be shifted in a controlled manner so that by pushing in or pulling out the Shaft arrangement the number of saw blades, which protrudes into the machining area, varies can be. This makes it possible to easily connect the saw station to different ones Adjust part thicknesses that require a different number of cuts.
- the sawing station according to the invention can on the one hand find an advantageous application in a sawing line in which the sawing station is arranged in the conveying direction after further sawing stations which cut planks on the two sides to be worked.
- This can be one or more additional sawing stations as described above.
- it is also provided to arrange a sawing station as described above after a row of sawing stations which process the tree trunk or the tree trunk part only on one side and which process the tree trunk or the tree trunk part in succession, preferably alternately, on different sides.
- the sawing station according to the invention to flow in and out in one Planing technique "to operate as described above, ie the tree trunk or the tree trunk part is driven through the sawing station and then moved back in the opposite direction. Because of the - advantageously mutually perpendicular - arrangement of the circular saws, the time-consuming turning after each sawing operation is eliminated.
- the sawmill according to the embodiment shown in FIG. 2 is a sawmill for Disassembling a tree trunk in a quarter cut and has a log task 1, one Trunk reducer 3, a debarker 5, a turning device 7, a first log band saw 13, a second block band saw 21 and a sawing road 29
- the log load 1, the trunk reducer 3 and the debarker 5 are conventional Wise designed.
- the logs are lifted with a gantry crane or abandoned directly from a truck and conveyed to the stem reducer 3, which is strong woody, i.e. strongly conical trunks reduced to a size to be processed. After that the possibly reduced tree trunk is debarked in debarker 5.
- the tree trunk is then guided to a turning device 7. There is the trunk qualitatively assessed and rotated so that zones of poor or good wood quality are possible exclusively in one of the four quadrants formed by the vertical and horizontal lie.
- the tree trunk After the tree trunk is aligned accordingly, it is placed over a suitable one Conveyor (not shown) to the vertical band saw 13, which the Tree trunk through a vertical cut essentially through the center in two Split stem halves.
- the two stem halves are now a longitudinal conveyor 17 to a cross conveyor 19 promoted, which separated the two trunk halves and a second vertical log band saw 21 feeds, while the trunk halves are oriented so that the Cut area of the previous cut is parallel to the horizontal.
- the block band saw 21 divides now by another vertical cut each of the two halves of the trunk in two Stammviertel.
- the strge pieces 29 consists of a central conveyor lane 31, on the sides of which are arranged alternating band saws TA 1 , TA 2 and TB 1 , TB 2 .
- the band saw TA 1 , TA 2 and TB 1 , TB 2 each separate a screed from a supplied log trunk, the log trunk being tipped between the sawing stations, so that the band saw TA 1 and TA 2 on the one hand and the band saw TB 1 and TB 2 on the other work the tree trunk quarter alternately on the two straight sides.
- the band saws are followed in the conveying direction by a circular saw station 33, the structure of which is shown schematically in FIGS. 3 and 4.
- the circular saw station 33 consists of two identical circular saws K 1 and K 2 with mutually perpendicular cutting planes, each circular saw K 1 or K 2 having a plurality of saw blades, four in the case of the present exemplary embodiment, which are arranged in a hollow shaft arrangement with shafts arranged one inside the other , which in the case of the circular saw K 1 are designated 35 1 , 35 2 , 35 3 and 35 4 (cf. FIG. 4).
- the diameter of the saw blades decreases towards the free end of the saws according to the pattern of the quarter cut.
- Hollow shaft circular saws for a cut with parallel cutting planes are generally known.
- the saws K 1 and K 2 are therefore not described in detail.
- the saw blades themselves are not shown, but only the respective cutting lines S1, S2, S3, S4 or S5, S6, S7 and S8.
- the circular saws K 1 and K 2 are somewhat spaced apart from one another in the conveying direction, so that the saw blades do not come into contact with one another.
- the diameters of the individual saw blades are selected so that the saw lines S1, S2, S3 and S4 can extend essentially up to the corresponding saw lines S5, S6, S7 and S8 according to the pattern of the quarter cut.
- the circular saws K 1 and K 2 each cooperate with a displaceable stop (not shown), the stop line A1 or A2 of which is indicated in FIG.
- the shafts 35 2 and 35 3 are axially displaceable relative to one another and with respect to the shaft 35 1 , while the shaft 35 4 is rigid with respect to the shaft 35 3 . Accordingly, the distance between the cutting lines S1 and S2 or S2 and S3 can be varied and thus set to a desired cutting thickness.
- the distance of the cutting line S1 from the stop line A1 can be varied by adjusting the stop (not shown) assigned to the circular saw K 1 . The same applies to the distance between A2 and S5 with saw K 2 .
- the (variable) thickness of the first screed defined by the distance between S1 and A1
- the thickness of the second and third screed can vary between 30 and 50 mm between S1 and S2 or S2 and S3
- the (Fixed) thickness of the fourth screed between S3 and S4 is approximately 30 mm.
- this information like the selection of the displaceable shafts described above, is only exemplary.
- all shafts or other shaft combinations can also be variably axially displaceable relative to one another.
- the circular saws K 1 and K 2 can be displaced overall in the respective axial direction R 1 or R 2 and can be wholly or partly moved out of the processing area, for example in such a way that only cuts along the lines S2 to S4 or S6 to S8 be carried out while the saw blades, which are intended for the cuts along the lines S1 and S5, lie outside the machining area. In this way, the number of cuts can be varied and the saw station can be adjusted to different log diameters. It is preferably provided that the saws K 1 and K 2 can both be displaced in the directions R 1 and R 2 , that is to say both in the axial direction and also perpendicular thereto, in order to match the two saws with respect to the thickness of the screed.
- the hollow shafts 35 2 to 35 4 can also be displaced from the concentric arrangement shown in FIGS. 3 and 4 into an eccentric position, so that in the event of an axial displacement of one of the hollow shafts of the saw K 1 in the direction R 1 , the a displacement of the crossing point of one or more of the cutting lines S1 to S4 with one of the cutting lines S5 to S8 causes the corresponding hollow shafts of the saw K 2 to be displaced relative to one another, likewise in the direction R 1 , into a position eccentric with respect to an outer hollow shaft, so that the sectional view shown in Fig. 3 is retained overall.
- the shaft 35 2 can be moved axially and the shaft, which defines the cutting line S6, can be moved in the direction R 1 , perpendicular to its axial direction, into an eccentric position.
- the third section thickness (S2 / S3) can be changed while maintaining the sectional view of FIG. 3 by an axial displacement of the shaft 35 3 and a displacement of the corresponding shaft of the saw K 2 in the direction R 1 .
- both circular saws K 1 and K 2 will be moved in the direction perpendicular to their axial direction (R 2 or R 1 ) or shift individual shafts in the corresponding direction to an eccentric position.
- the saws K 1 and K 2 can also be moved in the direction R 1 or R 2 (or in both directions simultaneously) to change the thickness of a first screed.
- planks are cut off in the band saw stations TA 1 , TA 2 or TB 1 and TB 2 in accordance with the neighborhood cut.
- the band saw stations TA 1 , TA 2 or TB 1 and TB 2 are cut off in the band saw stations TA 1 , TA 2 or TB 1 and TB 2 in accordance with the neighborhood cut.
- the remaining wedge that remains after processing by these stations is then completely broken down by the circular saw station 33 in accordance with the neighborhood cut.
- FIG. 5 shows a second embodiment of a tree cutting device according to the invention, in which the band saw stations TA 1 , TA 2 and TB 1 and TB 2 have been omitted and only a single circular saw station 33 is provided as described above.
- the circular saw station 33 then disassembles the supplied tree quarter in a single operation in this embodiment.
- This embodiment is particularly suitable for logs with a smaller diameter.
- the sawing station 33 can be set up in such a way that it works in the forward and reverse directions, so that the remaining wedge, which remains in the sawing station 33 after a first processing, is fed back to the sawing station 33 in the opposite direction, is further disassembled there , and so on until the entire tree trunk quarter has been dismantled.
