Definitions

  • the invention relates to a device for conveying and processing tree trunks with natural cone angle, with a longitudinal conveyor on which the logs are conveyed in a substantially parallel to its longitudinal axis conveying direction and fed to a downstream of the longitudinal conveyor arranged processing station, wherein the processing station immediately after one another comprising a horizontal milling cutter unit rotating about a first vertical axis and a vertical milling cutter unit rotating about a horizontal axis.
  • the invention further relates to a method for conveying tree trunks with natural cone angle, in which the tree trunks are conveyed in a substantially parallel to its longitudinal axis conveying direction and fed to a downstream processing station, wherein the tree trunks in the processing station directly behind one another at its top / bottom and milled on their right / left side.
  • longitudinal conveyors are used as standard assemblies, for example, to supply unprocessed or already partially processed tree trunks downstream processing stations such as cutting or sawing in the longitudinal direction.
  • the tree trunks are flattened by means of chipper heads on second, thus rotated with respect to the first pages by 90 ° sides, the chipper heads are laterally movable and / or pivotable about a vertical axis. They can therefore follow the lateral convex or the opposite concave curvature of the linearly supported by tree trunks.
  • the thus pre-processed logs are then conveyed non-linearly, namely along its curved center line. there they pass through a second processing station, namely a profiling station, in which the processing tools are fixed in space.
  • one side e.g. the lower and upper sides
  • the other sides e.g. the right and the left side
  • the logs between these stations are promoted by conveyors.
  • the document EP 0 634 254 A1 discloses a device with feed cars and a method for producing wood products from logs.
  • the device contains within a processing line about a horizontal axis rotating cutting heads and rotating about a vertical axis corner cutters.
  • the logs to be processed are fed via a horizontally movable feed carriage.
  • the log is oriented upwardly in the first processing with the convex arc, so it rests only at its both ends and is only laterally processed, while in the second processing it lies on an already flattened side and laterally is processed.
  • a device with feed cars and a method for producing wood products from logs are known.
  • the feed carriage is preceded by a Doppelwellenniksägeeaggregat. It contains a base frame on which a tree trunk can be clamped at both ends. This base frame is adjustable in height so that the tree trunk can be aligned in a vertical plane.
  • AT 382 106 B For example, a method and an apparatus for producing wood articles processed on all sides are known. This is a tree trunk on conveyed to a longitudinal conveyor via a dressing spanner, which at the thicker end of the tree trunk, the so-called "Erdende” at the bottom abspant.
  • the invention is the object of developing a device and a method of the type mentioned above to the effect that these disadvantages are avoided.
  • a tree trunk in a common station on all sides, i. on all four sides in order to be able to realize more compact plants and to guarantee a high dimensional accuracy, with conical, especially from additionally curved logs, wood products are produced, which run in a sectional view parallel to the center line of the raw tree trunk.
  • this object is achieved in that the longitudinal conveyor formed as a conveyor belt, conveyor chain or roller conveyor with conveyor rollers, employed to the conveying direction by half the cone angle to the horizontal and in dependence on the position of the logs on the longitudinal conveyor in height is movable.
  • this object is achieved in that the tree trunks of the processing station inclined by half the cone angle to the horizontal to the conveying direction, and in dependence on the conveying position of the tree trunks in height, by means of a conveyor belt, conveyor chain or roller conveyor fed with conveyor rollers formed longitudinal conveyor.
  • the invention has the advantage that the conical trunk is inclined and adjusted in height. As a result, an exact horizontal guidance of the center line of the tree trunk can be achieved. This applies regardless of the shape of the tree trunk on its sides, so that the invention can be used with particularly great advantage in installations of the type mentioned, as sold by the applicant under the name "Arcoline".
  • the horizontal milling unit is arranged in the conveying direction upstream of the vertical conveyor unit.
  • the horizontal milling unit has an upper horizontal milling cutter as well as a lower horizontal milling cutter arranged in a folding symmetry therewith.
  • the horizontal milling unit is spatially fixed during processing of a tree trunk in the conveying direction.
  • This measure has the advantage that a particularly simple structure is created, however, in this case, the diameter of the horizontal milling cutter must be so large that it covers not only the respective diameter of the tree trunk but also its curvature, because the tree trunk in its plane of curvature at the stationary held horizontal milling unit is conveyed over.
  • the horizontal milling unit can be moved transversely to the conveying direction during processing of a tree trunk.
  • This measure has the advantage that the horizontal milling aggregate can follow the curvature of the tree trunk by lateral movement, so that only smaller horizontal milling cutters are required.
  • the vertical milling unit has, analogously to the horizontal milling unit, preferably a left vertical milling cutter and a folding vertical symmetrical arranged right vertical milling cutter.
  • the vertical milling unit is pivotable about a second vertical axis.
  • This measure has the advantage that even tree trunks with a high curvature can be processed.
  • the second vertical axis intersects the horizontal axis of rotation.
  • the second vertical axis in an upstream position, is substantially tangential to a cylindrical surface defined by flight circles of teeth of circular saw blades disposed on a radial face of the vertical cutters.
  • the second vertical axis coincides at least approximately with the first vertical axis.
  • This third variant has the advantage that a common turntable can be provided, so that only two instead of three cylinders are required for adjusting.
  • the vertical milling unit can be moved transversely to the conveying direction in a horizontal direction.
  • hold-down for pressing the tree trunks are arranged on the longitudinal conveyor above the longitudinal conveyor, or procedurally the tree trunks are held down during conveying.
  • This measure has the advantage that the tree trunks are immovably held on the conveyor so that the processing tools can be controlled in accordance with a previously performed measurement of the contour of the tree trunk.
  • means for twisting curved tree trunks are provided such that a curved center line of the logs on the longitudinal conveyor comes to lie in a horizontal line, or there are procedurally curved tree trunks twisted such that a curved center line of the logs in conveying in a horizontal line comes to rest.
  • This measure has the already mentioned advantage that the invention can preferably be used for processing curved tree trunks.
  • the longitudinal conveyor is a chain conveyor or a roller conveyor.
  • FIGS. 1 to 4 Denotes 10 as a whole an embodiment of a device according to the invention.
  • a first conveyor 12 On a first conveyor 12 is a tree trunk 14, with a leading thin end 16 and thus a trailing thick end 17.
  • tree trunks can be processed in advance with thick end 17.
  • An arrow 18 indicates the conveying direction on the first conveyor 12, which in the FIGS. 1 to 4 from left to right.
  • the first conveyor 12 may be a conveyor belt, a conveyor chain or a roller conveyor with corresponding conveyor rollers.
  • the first conveyor 12 is preferably inclined at an angle ⁇ to the horizontal and is adjustable overall in height z, as indicated by arrows 13 in FIG FIG. 1 indicated. This measure is independent of the other features of the device 10 and can also be used in other devices.
  • logs 14 are of interest which are naturally curved.
  • R the radius of curvature
  • this can be down to 70 m for European trees or even further down to about 25 m for special trees overseas.
  • Tree trunks with even smaller radius of curvature are nowadays not commercially viable under industrial standards as sawmill lumber.
  • trees with a radius of curvature of more than about 900 m are processed by today's standards as "straight" wood, that is to say plants which are not specially designed for the processing of curved tree trunks.
  • the log 14 When the log 14 enters the area of the device 10, it has already been measured in advance with corresponding units (not shown) and rotated so that its curved center line 20 lies in a horizontal plane.
  • the tree trunk 14 also has a natural conicity with a half cone angle ⁇ .
  • the first conveyor 12 when the center line 20 is to lie in a horizontal plane, the first conveyor 12 must also be inclined by the cone angle ⁇ to the horizontal, such as FIG. 1 shows.
  • the thick end 17 of the tree trunk is slightly downstream of a rearmost support point 22 of the first conveyor 12.
  • the vertical distance of the rearmost support point 22 to the center line 20 is in this position z. 1
  • the log 14 is now transported on the first conveyor 12 in the conveying direction 18 and thereby pressed by means of pressure rollers 24 and 26 fixed to the first conveyor 12.
  • This means that the tree trunk 14 does not change its orientation relative to the conveying direction 18 when it is transported on the first conveyor 12 because the pressure rollers 24 and 26 press the tree trunk 14 firmly onto the first conveyor 12.
  • This orientation in the conveying direction 18 is maintained throughout the passage through the device 10.
  • a horizontal milling unit 30 Downstream of the first conveyor 12 there is a horizontal milling unit 30 rotating about a vertical axis with two milling cutter heads or chipper heads arranged in a symmetrical manner with respect to one another, namely an upper horizontal milling cutter 30a and a lower horizontal milling cutter 30b.
  • the horizontal milling unit 30 is spatially fixed during processing in the conveying direction 18. Of course, this does not preclude the horizontal milling unit 30 from being adjustable in one or more directions between machining operations for adjustment purposes or for optimizing differently shaped logs 14.
  • the horizontal milling unit 30 laterally, ie transversely to the conveying direction 18, be designed to be displaceable, as with arrows 33 in FIG. 2 indicated. Then the horizontal milling unit 30 can follow the curvature of the tree trunk 14 and the horizontal cutters 30a, 30b only have to be dimensioned in their diameter so large that they cover the diameter of the tree trunk 14.
  • the device 10 Immediately behind the horizontal milling unit 30, the device 10 has a vertical milling unit 34 with a left vertical milling cutter 34a and a folding vertical symmetrical arranged right vertical milling cutter 34b.
  • the order of the cutter units 30, 34 is arbitrary per se. Preferably, however, when in the order shown in the drawing, i. when the horizontal milling unit 30 is arranged upstream in the conveying direction 18.
  • the vertical milling unit 34 is not spatially fixed, but pivotable about a vertical axis.
  • a second conveyor 42 Immediately behind the vertical milling unit 34 is a second conveyor 42, on which the processed tree trunks 14 can be conveyed away in a direction indicated by an arrow 44 conveying direction.
  • the horizontal milling cutter unit 30 has the purpose of cutting off an as yet unprocessed tree trunk 14 from an upper area 52a and a lower area 52b in order to produce a flat upper side or lower side there.
  • the vertical milling unit 34 on the other hand, shoulders off a left-hand region 54a and a right-hand region 54b, in order to produce there likewise a flat right or left-hand surface. After passing through the two units 30 and 34 thus remains of the unprocessed tree trunk 14 in a cross-section example square or rectangular model 50th
  • the tree trunk 14 Since the tree trunk 14, as already mentioned, lies with its center line 20 in a horizontal plane and the orientation of the tree trunk 14 relative to the conveying direction 18 remains unchanged, only in the area of the vertical milling unit 34 the natural curvature must be taken into account. This is done by adjusting the vertical milling cutter assembly 34 continuously in position and orientation as a function of the curvature of the log 14 along its axis 20.
  • the vertical milling cutter assembly is one in the manner already mentioned Vertical axis 36 and 36 'and 36 "pivoted and / or horizontally transversely to the conveying direction 18 movable.
  • the first conveyor 12 is designed to be adjustable in height z, as already mentioned.
  • the movement of the tree trunk 14 on the first conveyor 12th detected and driven a lifting mechanism (not shown) for the first conveyor 12, which lowers it in the direction of the arrows 13 (thin end 16 ahead) or raises (thick end 17 ahead).
  • the first conveyor 12 is lowered to 12' or its rearmost support point 22 to 22 ', as in FIG. 3 located.
  • the vertical distance of the rearmost support point 22 'to the center line 20 is then z 2 .
  • the front end 16 ' has already passed the corresponding tilted and / or moved vertical milling unit 34' and assumed the shape of the model 50.
  • the model 50 is carried away on the second conveyor 42.
  • FIGS. 5 and 6 show the situation in the area of the vertical milling unit 34.
  • FIG. 5 represents one of the two vertical milling cutters, namely the left vertical milling cutter 34a in section. It can be seen that the vertical milling cutter 34a essentially consists of an approximately truncated conical base body 60.
  • the base body 60 has a right side processing page 62 on which the wood is spanked.
  • the drive shaft, the drive itself, etc. are not shown for clarity.
  • the base body 60 is provided on the machining side 62 with a radial end face 63 into which a region 64 is sunk.
  • the sunken portion 64 is rotationally symmetrical about the axis 32 around and at its periphery by an annular shoulder 65 limited.
  • the recessed area 64 thus occupies a substantially circular cylindrical volume. This volume has a diameter D and a height h.
  • a circumferential edge 66 whose width is b, remains physically of the radial end face 63.
  • the width b is in FIG. 5 exaggeratedly illustrated. In reality, she is as narrow as possible.
  • annular circular saw blade 68 On the edge 66, an annular circular saw blade 68 is mounted, whose teeth are designated 70.
  • the circle of teeth of the teeth lies in the plane of the radial end face 63.
  • a frustoconical jacket 72 of the base body 60 is provided in a known manner with Spanermessern 74.
  • a circular arc 75 is shown in phantom, which represents the convex curvature of the tree trunk 14 with the radius R.
  • the radius R is the minimum radius of curvature permissible for the vertical splitter 34a, for example 25 m. It can be clearly seen that at this minimum radius of curvature R, the circular arc 75 is just inscribed in the axial section of the recessed area 64, ie that the circular arc 75 just touches the bottom of the area 64 and just passes by the upper edge of the annular shoulder 65.
  • FIG. 6 illustrates the processing situation of the vertical milling unit 34. It can be clearly seen that the tree trunk 14 with the curvature of his in FIG. 6 extends left side in the depressed area 64a, thereby avoiding a collision between the log 14 and the Vertikalspaner 34a in its center.
