Definitions

  • the invention relates to a device for producing flat wood products, such as boards, which are separated from the two opposite sides of a longitudinally moved squared timber by at least one oscillating knife.
  • the invention is therefore based on the object of designing a device of the type mentioned at the outset in such a way that curvatures of the wood products caused by production are largely eliminated.
  • a straightening bending device is arranged immediately behind each knife, which has an adjustable bending roller and on the other side of the wood product has a rotating counter-tool with a flexible pressure surface, the flexible pressure surface being driven in such a way that it Severing a pull on the wood products.
  • the device according to the invention gives the possibility of quickly and easily adapting the parameters of the straightening bending process to the respective need, so that even with very different influencing variables it is ensured that the wood products are obtained in a straight form.
  • a bending device for wood which has an adjustable bending projection and, on the other side of the workpiece to be bent, an endlessly rotating, flexible link chain as a counter tool is known (US Pat. No. 1,783,187).
  • this known device only serves to give originally straight wooden workpieces a predetermined curvature.
  • This device is therefore neither suitable nor intended to be used in direct connection with a device for producing wood products which have been separated without cutting and which are to be produced in a straight form.
  • the device shown in FIG. 1 is used by a squared timber produced from a tree trunk 19 on both Separate sides of boards 10 or similar flat wood products without cutting.
  • the log 19 is advanced in its longitudinal direction by transport devices (not shown) and smoothly milled on its two opposite sides by milling cutters 20.
  • a board 10 is cut off on both sides by knives 21 without cutting.
  • the knives 21 perform oscillatory movements.
  • a pressing tool 22 presses in the vicinity of the cutting edge of the knives 21 against the outside of the wood, as a result of which the separation process is favorably influenced and at the same time precise guidance of the wooden trunk 19 or of the model or squared timber produced therefrom is achieved.
  • a belt reel 2 is rotatably mounted in the machine frame (not shown) of each of the two straightening bending devices. It is driven by a preferably speed-controllable motor arranged in the machine frame.
  • a second belt reel 5 is rotatably mounted on the end of a swivel arm 7 mounted in the machine frame.
  • a hydraulic cylinder 8 supported on the machine frame is articulated with its piston rod on the swivel arm 7.
  • An endless belt 9 runs over the belt rollers 2 and 5 and, in the exemplary embodiment shown, is designed as a rubber belt with a fabric insert.
  • the upper run of the belt 9 forms a continuously running, flexible pressure surface for the boards 10 or the like to be bent.
  • the curved board 10 is pressed against the belt 9 by a bending roller 11.
  • the bending roller 11 is rotatably mounted on an arm 12 pivotably mounted in the machine frame, which is pressed by means of a hydraulic cylinder 13 which is also supported on the machine frame.
  • a predetermined tension is given to the belt 9 by the hydraulic cylinder 8, as a result of which the contact pressure for the board 10 acting between the belt 9 and the bending roller 11 is set.
  • the wrap angle between the board 10 and the bending roller 11 is changed. From the coordination of these two influencing variables, the bending effect is obtained, which is set so that the original curvature of the board 10 is eliminated, so that a straight board is obtained.
  • the straightening bending device shown in greatly simplified form in FIG. 2 differs from the straightening bending device according to FIG. 1 only in that the continuous, flexible pressure surface for the board 10 is not formed by a belt 9, but by the tread 17 of a x hollow tire 18, which just as the belt 9 can be driven by a motor.
  • the bending roller 11 is adjustable by a cylinder 13 as described.
  • the internal pressure of the hollow tire 18 is expediently changed.
  • the belt rollers 2 or the hollow tire 18 are driven in such a way that the boards 10 are moved away from the separation point under tension, which results in a favorable influence on the separation process.
  • a straightening bending device is preferably assigned to each knife 21 in the manner shown in FIG. 1.
