Definitions

  • the invention relates to a method for the longitudinal orientation of chips, in particular in the course of the production of OSR boards (Oriented Strandboard) with rotating discs which are arranged one behind the other in a fleece direction over a moving substrate which accommodates the fleece and which is at a corresponding distance from the shafts each have the same distance.
  • OSR boards Oriented Strandboard
  • a device for producing a directional wood particle of different dimensions containing chipboard has become known (DE-PS 11 74 058), in which a plurality of mutually movable, connected to a drive device alignment elements which are inclined to the horizontal, substantially parallel to the oblique Forming area of the chip mat extending plane and are arranged substantially parallel to each other with the formation of narrow alignment passages, the width of these passages and also the distance between the lower edges of the alignment elements on the one hand and the training area of the chip mat on the other hand is slightly larger than the average length for wood particles. Due to the relative movement of the alignment elements relative to one another and the spacing of the elements from one another, such a device is not suitable for the longitudinal orientation of chips in the course of the production of OSB panels.
  • the spacing of the alignment elements from one another allows the chips to be oriented longitudinally to be positioned transversely to the longitudinal orientation again in the area of the alignment elements, since only essentially lie next to one another along the common chord the disks have a longest guide of the chips to be oriented lengthways, but are fastened on two different shafts arranged one behind the other.
  • the problems of orientation grow with increasing chip dimensions and reach their maximum when orienting strands.
  • the beaches to be oriented exist made of wood particles, the dimensions of which do not correspond to the defined chip dimensions for the production of normal chipboard. Namely, wood particles (strands) are oriented, which are preferably 70 mm long, 10 to 30 mm wide and have a thickness of 0.5 to 1 mm; Even with such wood processing, splinters and extreme oversize cannot be avoided unless additional complex sorting and post-treatment devices are provided.
  • the object of the invention is to propose a method and a device for carrying out this method, in which there is clear guidance in the entire vertical region of the longitudinal orientation and that there are no elements in the straightening region which hinder the oriented depositing of the chips, that can lead to blockages.
  • This object is achieved by the inventive method disclosed in the characterizing features of claim 1.).
  • the inventive method step according to claim 2) causes the chips, in particular the strands, to tilt, which contributes significantly to the non-blocking penetration of the strands between the disk walls.
  • a device for carrying out the method according to claim 1) and / or 2) is placed under protection, with the interacting disks that meh Several shafts arranged one behind the other form the division of a rotating disc gate, at the same time also represent the respective rotating disc wall and, by selecting the distance in the region of the average half chip length, bring about complete orientation.
  • the design of the subject of the invention according to claim 5) serves to keep the wall clean on both sides by cleaning the partially touching panes sliding past one another.
  • outermost disks are used in each case, which have spikes arranged on their outside in the radial direction. This configuration according to the invention also avoids blockages of these passage openings in this area.
  • the throw-back roller placed under protection serves in particular with a very small division of the disk walls for the reorientation of chips or beaches to be oriented that are too long.
  • an unoriented stream of chips 5 is placed as a oriented fleece 6 on a forming belt 1 via first disks 2 and second disks 3 arranged on rotating shafts 4.
  • the shafts 4 are arranged in a housing 16 which can be moved in height in order to be adapted to the angle of repose.
  • the orientation in the prior art now takes place through the first panes 2 and the second panes 3.
  • the projection of the first panes 2 covers the second panes 3 only in one minimal area, so that the distance 7 between the first disks 2 and the distance 7a between the second disks 3, which is equal to the distance between the first disks 2, are used for orientation.
  • Fig. Lc represents a section through Fig. 1, which has taken place at the level of the lower imaginary separation of the first slices 2 and second slices 3.
  • the disks used for orientation according to the prior art are only partially oriented in the area of a region 12, guidance only from the imaginary entry of the first and second disks 2 and 3 to the imaginary one in the area of the plane 13 The first and second disks exit.
  • FIGS. 2a, b, 2c show the pane arrangement according to the invention in cooperation with FIGS. 2a, b and 2c.
  • the cuts made in this way which are shown in FIGS. 2a, 2b, 2c, show that, according to the invention, the entire non-oriented chip flow 5 is caused by a closed disk gate rotating from the first disks 2 and, in the example, the same size of the second disks 3 Gate division 10 is transported through and complete guidance from a first disc contact 14 to a last disc contact 15 is maintained in the vertical direction.
  • the closed rotating disk creel 11, consisting of the first disks 2 and the second disks 3, is designed so that it can be raised relative to the forming belt 1 in such a way that it can be aligned over the fleece 6 in accordance with the angle of repose of the oriented chips for the production of OSB boards.
  • FIG. 4 shows an embodiment of the subject matter of the invention, as is ensured by additional measures (pairing large and small disks) in the conveying direction (FIG. 4) and transversely thereto (FIG. 4b) that the beach or the chip flow is discharged and entered.
  • Fin resulting gap 17 between the housing 16 and the large first and second small disks 2, 3 ' is interrupted by spiked disks 18, which are also arranged on the shafts 4, with the help of which the chips or beaches which may accumulate there the gap 17 are transported.
  • FIG. 4 shows a device according to the invention in cooperation with a pre-dissolution of the chip material to be oriented for the production of OSB boards and a return roller.
  • Several such shafts 4, provided with disks 2, 2 'and 3, 3', are arranged one behind the other in the housing 16, in such a way that the large disks of one shaft 4 interact with the small disks of the following shaft 4.
  • the non-oriented chip material 5, which is pre-dissolved by pre-dissolving rollers 20, 21, is fed to the upper inlet of the closed rotating disc gate 11.
  • the return roller 22 has spikes 23.
  • Auxiliary devices 24, 25 are provided on the housing 16, by means of which the housing 16 can be raised against the horizontal position of the forming belt in accordance with the angle of repose of the oriented fleece 6 (see double arrow 27).
  • the pre-dissolving rollers 20, 21 and the throw-back roller 22 can be separated ten clad scaffold 26 may be arranged, into which the unsorted chip stream 5 falls from above.
  • the directions of rotation of the successive rotating shafts 4 can also be selected alternately clockwise and counterclockwise.
  • the return roller 22 which is arranged above the last roller, and to rotate it in the opposite sense. If the last rotating roller 4 rotates counterclockwise, this return roller can be omitted.
  • 4a also schematically shows an arrangement of rotating shafts 4, in which the increased self-cleaning effect by arranging these disks is to be described only on a row of equally sized first and second disks 2 and 3.
  • the disc 2a cooperates with its outer side surface 30 with the inner side surface 31 of the disc 3a, while its outer side surface 30 cooperates with the inner side surface 31 of the disc 2.
  • the disks 2, 3, 2a and 3a it is also possible for the disks 2, 3, 2a and 3a to be arranged in such a way that in each case the inner side faces 31 of the following ones Interact pane with the outer side surfaces 30 of the previous pane in the sense of an additional self-cleaning.
  • 4b shows, using the example of large disks and small disks 2, 2 'and 3, 3' mounted on a shaft 4, clearly as a chip 29 due to the different diameters of successive disks into the gate, which has a gate division 10, which is slightly is greater than half the chip length. As can be seen, this takes place in that the distance between disks 2 and 3, 2 'and 3' of equal size is slightly larger than the average length of a chip to be oriented.
