Definitions

  • the invention relates to a device for leveling boards and the like. by means of rollers arranged in a frame, between which the boards are passed.
  • the boards produced in the described chipless cutting technique and the like have a twist in addition to the curvature mentioned, i.e. they are rotated or coiled around their longitudinal axis. This deformation precludes automated further processing of the boards in numerous applications.
  • the twist that occurs is stronger, the more inclined the cutting edges separating the board are from the longitudinal direction of the trunk.
  • the object of the invention is therefore to provide a device for straightening boards and the like. to create, which makes it possible to permanently eliminate the described twist of the boards in the simplest possible workflow.
  • a board guide channel extending in the longitudinal direction of the frame and having a twist approximately about the longitudinal axis of the frame is formed in that several pairs of rollers are connected in series, each of which is pivoted about the longitudinal axis of the frame relative to the respective previous pair of rollers.
  • the boards pass through the board guide channel formed in this way, which has a swirl opposite to the swirl of the boards.
  • the boards experience a continuous twist in the opposite direction to their twist.
  • the boards are straightened so that they then have a permanent flat shape.
  • the device according to the invention can therefore be arranged directly after the device for cutting the boards without cutting or with the interposition of a straightening bending device.
  • Another embodiment within the scope of the invention provides that two conveyor belts extend from a pair of input rollers to a pair of output rollers interlaced with one another, that the two mutually facing strands of the two conveyor belts having a swirl form the board guide channel between them, and that at least one of the conveyor belts is driven is.
  • the boards are guided completely continuously by the conveyor belts.
  • the pairs of rollers can be pivoted so that a different amount of twist of the board guide channel can be set in accordance with the respective requirements.
  • the respective lower rollers of each pair of rollers or the rollers guiding the lower conveyor belt are expediently foldable downward so that wood residues, which can occur, for example, in the case of defective wood, can be easily removed from the device.
  • the two rollers of each pair of rollers are mutually adjustable in order to enable adaptation to different board thicknesses.
  • the device shown in FIGS. 1 to 4 has a frame t which essentially consists of two portal-like stands 2 and 3 at the entrance and exit of the device and of an axis 4 which connects the two stands 2, 3 and extends in the longitudinal direction of the frame consists.
  • the axis 4 forms a pivot axis for a plurality of roller frames 5, which are connected in series and each have a pair of rollers 6, which consists of an upper roller 7 and a lower roller 8 arranged parallel and at a distance from it.
  • the roller frame 5a arranged at the frame entrance is shown with normal lines.
  • the roller frame 5 arranged at the exit is shown in FIG. 2 in thin lines.
  • the roller frame 5 is pivoted about the axis 4 with respect to the roller frame 5a.
  • the pivot axis 4 extends centrally in the first roller frame 5a, ie the dimension a entered there is equal to the dimension b.
  • the pivot axis 4 runs off-center, ie the dimension a is significantly smaller than the dimension b.
  • all the roller frames 5 are pivoted or interleaved by a certain angular amount about the longitudinal axis of the frame relative to the previous roller frame.
  • FIG. 2 This creates a board guide channel 9 (FIG. 2) running in the longitudinal direction of the frame, which has a swirl over its entire length.
  • the boards 10 to be straightened (FIG. 1) run through this board guide channel 9 and, in their initial state, also have a swirl which is opposite to the swirl of the board guide channel 9. After passing through the board guide channel 9, the boards 10 emerge straight, as indicated in FIG. 1.
  • the swirl angle of the board guide channel 9 is selected by pivoting the roller frame 5 so that it causes a permanent deformation in the boards 10 to be machined, which just compensates for the original swirl of the boards 10.
  • each of the roller frames 5 is connected to a swivel drive 11, which is formed, for example, by a pressure medium cylinder which engages on a lateral arm 12 of the roller frame 5.
  • At least one roller 8 in the output-side roller frame 5 is provided with a roller drive 12 which serves to convey the board 10 until it exits the device.
  • each roller frame 5 or 5a can be folded down, as shown in FIG. 3.
  • a pressure medium cylinder 14 which forms a folding drive, engages on an arm 15 of the frame part 13.
  • Leftover wood or board parts that have accumulated or clamped in the board guide channel 9 can be removed in this way simply by opening the rollers 8, these residues either falling off by themselves or being easily removed.
  • Fig. 4 shows in a plan view the lateral offset of the successive roller frame 5.
  • Fig. 4 also shows that the boards 10 to be straightened in the most important application of the device according to the invention are separated from a laterally flattened log 16 by a knife 17.
  • a straightening bending device 18 which eliminates a curvature of the boards 10
  • the boards 10 immediately enter the device which eliminates the twist of the boards.
  • the size and direction of this swirl essentially depends on the inclination of the cutting edges 17.
  • the modified device shown in FIGS. 5 to 7 differs from the device described above and shown in FIGS. 1 to 4 essentially only in that the individual roller frames 5 connected in series can be pivoted about an approximately longitudinal axis of the frame coinciding with the board guide channel 9 .
  • the roller frames 5 each form a ring in which the rollers 7, 8 are mounted.
  • These ring-shaped roller frames 5 are each guided in a link guide in a guide part 19 on a circular path, in the center of which is the longitudinal axis of the frame.
  • roller frame 5 is designed to be foldable.
  • a worm drive 21 is provided as a swivel drive, which drives a worm segment 22 on the annular roller frame 5 by means of a servomotor 23.
  • the upper roller 7 is adjustable relative to the lower roller 8 in each roller frame 5 or 5a.
  • the upper roller 7 can be pivoted on lateral supports 24 about a pivot axis 25.
  • the swivel adjustment is carried out by a pressure medium cylinder 26.
  • Two conveyor belts 27, 28 extend from a pair of input rollers 29, 30 to a pair of output rollers 31, 32 which are entangled with them.
  • the two conveyor belts 27, 28 thus have a twist as seen in their longitudinal direction; they form between them the board guide channel 9, also provided with a twist, through which the board 10 to be straightened runs.
  • the set conveyor belts 27, 28 can be rubber bands provided with a fabric insert or metallic link belts or chain belts.
  • each crowned support rollers 35, 36 may be arranged (Fig. 10). At least one of the two conveyor belts 27, 28 is driven so that the boards 10 passing through are completely conveyed out of the device.
  • Fig. 10 it is shown that the pair of rollers 31, 32 on the output side can be pivoted relative to the pair of rollers 29, 30 on the input side in order to change the twist angle of the board guide channel 9 formed in order to adapt to the respective work requirements.
  • a swivel drive 37 is used for this purpose, which guides a roller frame, which is designed here in two parts, on a circular path formed by a circular cutout 39.
  • an adjustment drive 40 is provided on the two pairs of rollers 29, 30 and 31, 32, which, in the manner already described, adjusts the upper roller 29 and 31 relative to the lower roller 30 and 32 to adapt to different board thicknesses enables.
  • rollers 30, 32 carrying the lower conveyor track 28 can be folded down in order to open the board guide channel 9 when wood fragments obtained there have to be removed.
  • roller pairs 7, 8 arranged one behind the other can also be aligned such that a curved course of the board guide channel 9 is achieved. In this way it is possible to align the board 10 in its longitudinal direction, so that a separate straightening device 18 can be omitted.
