Definitions

  • the present invention refers to a device for working a timber log.
  • the invention also refers to a method of working a timber log.
  • the cutting edges are arranged to provide two plane parallel recesses in a log which is brought to pass the knives, whereafter a saw blade is provided to saw along a limiting surface of these recesses in such a manner that a sideboard is removed from the rest of the log.
  • edges of a log which is rectangulary shaped by saw cuts, are milled perpendicularly by means of cutting heads, which comprise cutting knives and a circular saw blade.
  • cutting heads which comprise cutting knives and a circular saw blade.
  • One of the surfaces of the milled portion is thereby evenly sawn.
  • the saw cuts are applied in essentially the planes of the second of the surfaces of the milled portion, which due to the influence of the cutting knives gets a wave-shaped appearance.
  • the waves are removed and all the sides of the product are evenly sawn.
  • the material milled away is to a large part chip, which is desirable since it may be used for the production of cellulose.
  • both of these known methods and devices result in the fact that the surface which is produced by the cutting knives along the longitudinal direction of the log is wave shaped.
  • the wave-shaped surface may be removed or evened by an accurate guiding of the saw blade along this wave-shaped surface. If, for any reason, the saw blade does not run exactly along said surface but leave it untouched along a portion of the log, this wave-shaped surface will appear on the board adjacent to the sideboard, on which a surface is defined by the sawing separation of the sideboard.
  • EP-A-775 558 discloses working of a timber log by means of a band saw, which has a saw band extending transversally through the log, i.e. the band saw is arranged to separate a sideboard from the log. After the separation of the sideboard, the sideboard is maintained in its original position by supporting elements, whereby the chipping out of the wane portion of the sideboard is performed on this separated sideboard.
  • US-A-4,848,427 discloses another method and apparatus for chipping out the wane portion of a timber log.
  • the chipping out takes place in two steps, which are performed with a respective combination working tool.
  • Each of these working tools comprises a saw blade and a chipping tool arranged around a common axis of rotation. Consequently, the solution presented in US 4,848,427 differs from the solution of the present invention in that no simple saw groove is obtained in the first working step.
  • US-A-4,848,427 describes a working method operating in an order differing from the working order of the present invention.
  • the first working step according to this prior art includes simultaneous chipping out and sawing a groove. The remaining part of said groove extends in a plane perpendicular to the saw plane for separating a sideboard, but not in a plane being parallel to and substantially coinciding with the following sawing step for separating the sideboard.
  • An object of the invention is to provide a device for chip cutting separation of timber logs, wherein the device enables the achievement of a maximum quantity of chip in connection with the separation of portions comprising wanes, at the same time as the working tool used is prevented from causing the unwanted surface defect of the boards defined by the chip cutting working.
  • the chip cutting working tools must not leave any wave-shaped surface which in turn is to be finished by means of an successive saw blade or any further working member.
  • the rotation axis of the working tool is arranged to extend in a plane being essentially parallel to the extension planes of said first and second surfaces and a rotation axis of the working tool is arranged to extend essentially perpendicular to said transport direction.
  • the device comprises a finishing tool, arranged to finish a third surface of the log, which surface forms an angle to said second surface and together therewith defines the portion which has been removed from the log. Thanks to the finishing tool, it is prevented that the third surface, which in this case is intended to form a narrow side surface of a sideboard, becomes rough in connection with the chip cutting working.
  • the finishing tool is provided on the working tool and comprises a cutting edge extending in a plane being essentially perpendicular to said rotation surface.
  • the saw tool comprises a rotary saw blade, and the saw blade and the working tool are arranged in such a manner that their outer peripheries overlap each other in said log transport direction.
  • the difficulty of positioning the working tool accurately is reduced in such a manner that the working tool will not engage said second surface, in particular when the logs to be worked are curved.
  • the device comprises four working tools and saw tools, arranged to remove four separate portions of the log, which each comprises a respective wane. In such a manner, it is possible to remove all four wanes of the log in parallel and at a location along a path along which the log is transported.
  • a further object of the invention is to provide a method, which enables the removal of a portion of a log comprising a wane without causing, by the chip cutting working tool, any wave-shaped surface of the log, which later on need to be finished by means of any further working tool, such as a saw blade, for instance.
  • a third surface of the log is finished by means of a finishing tool, wherein said third surface forms an angle to said second surface and together therewith form a limitation of the log to the portion being removed.
  • Fig 1 and 2 are schematical views of an embodiment of the device according to the invention, which comprises a combination tool 1, having six cutting knives and a saw blade of a type known per se, by which side portions having a curved outer surface of the log is removed in a conventional manner.
  • the device comprises four such combination tools 1, arranged to work the log in such a manner that it receives an essentially rectangular cross-section with the exception that the curved corners, containing wanes, are left. This also appears from Fig 5 which schematically discloses how the log is worked initially.
  • the device also comprises a number of saw tools 2, one of which is disclosed in Fig 1 and which are arranged to saw grooves in the log along the longitudinal direction thereof when it is transported passing the saw tools 2 in a transport direction x.
  • the saw tool 2 comprises a blade 16.
  • the blades 16 of the saw tools 2 are displaced towards the centre of the log in relation to a respective adjacent, plane parallel saw blade of the combination tools 1 by such a distance that the wane or a portion comprising the respective wane is comprised therebetween.
  • the saw blade of the combination tool 1 and/or the saw tool 2 is displaceable in a direction 4 which is perpendicular to said transport direction x in such a manner that the distance therebetween maybe adjusted dependent on the thickness of the log.
  • the saw tools 2 are provided in pairs, the blades 16 of which are arranged in essentially the same plane.
  • One such pair is disclosed in Fig 2, and at least one of, preferably both the saw tools 2 is displaceably provided in a direction x which is perpendicular to the transport direction z and to the transverse direction y.
  • the depth of the groove sawn by the saw tool 2 may be adapted to different log dimensions.
  • the saw tool 16 is arranged to provide a groove 10, or a channel, having a first surface 7, a second surface 8, which is essentially parallel to the first surface 7, and a bottom 17 which extends between and connects the first surface 7 and the second surface 8 to each other.
  • the device Immediately after the saw tools 2, seen in the transport direction x, the device comprises a working tool 3.
  • the rotation axis r of the working tool 3 forms an angle to the rotation axis r of the saw tool 2. In the embodiment disclose said angle is essentially perpendicular. Thereby, the rotation axis r of the working tool 3 extends essentially in the previously defined direction z.
  • the working tool 3 comprises an element defining an essentially plane disc 4 on which chip cutting knives 5 are provided.
  • the knives 5 are provided to project from the outer periphery of the disc 4. They comprise an edge 6 which, during the rotation of the tool 3, is arranged to define an imaginary rotation surface touching a plane being essentially parallel to the first and second surfaces 7, 8 respectively, formed at a log 9 when the saw tool 2 produces the groove 10.
  • the extension of said rotation surface appears by the dashed line 11 in Fig 3.
  • the working tool 3 is arranged to be positioned in such a manner that said rotation surface 11 extends right to the first surface 7 but not to the second surface 8. Thereby, it is avoided that the cutting edge 6 engages the second surface 8 and produces a wave formation thereat.
  • the sideboard 9' which later on is to be separated from the log 9, will form a fixed part of the log 9 during the whole chip cutting working.
  • the device comprises finishing tools 12, which are provided on the working tool 3 and comprise a respective cutting edge 13 extending in a plane being essential perpendicular to said rotation surface 11, i.e. parallel to the extension plane of the disc 3.
  • the finishing tool 12 is arranged to work a third surface 15 of the log 9, which is perpendicular to the second surface 8 of the latter and together therewith encloses and defines the portion 14 having the wane.
  • the third surface 15 is indicated in Fig 5 and 6 and appears more clearly from Fig 8.
  • the working tool 3, including the finishing tool 12, is of a known type per se. In particular, it is the positioning thereof in relation to the saw tool 2 which is the interest of the invention.
  • Figs 5-7 disclose how a log is stepwise worked when it is forced to pass combination tools 1, saw tools 2 and working tools 3 along a path.
  • combination tools 1, which are plane parallel to the most adjacent saw tool 2 have been disclosed in Fig 1 and 2.
  • combination tools 1, provided perpendicularly thereto, are provided preferably upstream in the transport direction x.
