Definitions

  • the invention relates to a device for longitudinal orientation of elongated wood chips, especially for the production of Boards with oriented chips, according to the generic term of the Claim 1.
  • Panels with oriented chips which in professional circles as OSB panels (oriented strand board) Chipboard with higher strength properties.
  • OSB boards Long wood chips are used in the production of OSB boards (Strands) oriented on a ribbon, and then pressed into plates. Usually they have Wood chips a length of 100 - 150 mm, a width of 10 - 30 mm and a thickness of 0.4 - 1.0 mm.
  • the OSB panels own usually a 3-layer structure, but recently for the use of different glue systems also 5-layer Plates are made.
  • this disc orienter The principle of operation of this disc orienter is based that the diarrhea chutes are narrower than the length the wood chips and therefore the wood chips are not oriented transversely can step through.
  • the wood shavings that hit the Disc orienters will not step straight through by rotating the disc rollers in the same direction Movement and thereby change their orientation, until they are oriented approximately longitudinally and fall into the diarrhea slots.
  • Wood chips in different orientations in all three axes fall through the diarrhea slit.
  • Wood chips from e.g. the dimensions 100 x 20 x 0.5 mm and the wood chips can have a diarrhea slot with a width of 30 mm step down with the front edge 20 x 0.5 mm, with the side edge 100 x 0.5 mm or with the surface 100 x 20 mm length-oriented, as well as any combination of these. ever depending on the type of case, it can deviate more or less from the ideal longitudinal orientation.
  • DE-OS 195 44 866 is another embodiment of a mechanical device for longitudinal orientation of wood chips known.
  • a plurality of parallel and Wall elements arranged vertically next to each other and associated elongated orientation elements arranged.
  • the orientation elements are on a drive connected and can perform a movement that a Component along and vertical to it.
  • From GM 297 07 143 is a device for aligning and Dropping of elongated particles known in which the Degree of orientation of the particles with high throughput can be improved.
  • This is an embodiment variant provided with a mechanical orientation unit is provided in the direction of movement of the pad has vertical straightening surfaces, with adjacent Straightening surfaces can be driven in the opposite direction.
  • the movement of the straightening surfaces is parallel to the moving one Underlay and also has movement components perpendicular to Base for the longitudinal orientation of the wood chips.
  • the invention has for its object a device for Longitudinal orientation of elongated wood chips at the beginning to improve the type mentioned so that an exact Longitudinal orientation of the wood shavings is achieved and thus panels with improved strength properties can be produced can.
  • Orientation unit Due to the configuration of the Orientation unit as chamber rollers, they fall to orienting wood chips between axially adjacent disks on blade elements. They lie on the blade elements Wood chips flat, which gives them a defined position take in. With the further rotary movement of the chamber roller the wood chip slides with its at a certain point Front edge in the direction of the forming belt.
  • the wood chips When it hits the forming belt, the wood chips are opened Forming belt speed slowed down or accelerated and then at the belt speed of the Blade elements subtracted. Through this process of Pulling off will further improve the longitudinal orientation achieved because the wood chips only with the rear edge on the The transport sheet is resting on it and rubbed into the Longitudinal axis are rotated.
  • FIG. 1 schematically shows a molding station 1 with a Dosing hopper 2, which has a discharge roller arrangement 3, Distribution rollers 4, an orientation unit 5, and a Form tape 6 shown.
  • a material flow over the Discharge roller arrangement 3 carried out.
  • the non-oriented Material flow consists of flat elongated wood chips that usually a length A of 100 to 150 mm, a width B of 10 up to 30 mm and a thickness C of 0.4 to 1.0 mm. This glued wood chips first reach the distributor rollers 4 which distribute the chip flow to the orientation unit 5.
  • the orientation unit 5 consists of chamber rollers 7, which in Direction of conveyance (represented by arrow 8) one after the other are arranged and with constant speed in Are driven clockwise.
  • the chamber rollers 7 exist made of rotating shafts mounted and driven in a housing 9, each with a predetermined number vertically aligned discs 10 are arranged axially spaced.
  • the disks 10 have the same distance. In In a further embodiment, the distances can be more adjacent Rolls with different axial disc spacing dimensions be executed. This gives you a Separation of smaller and larger wood chips.
  • the disks 10 shown all have the same Outer diameter. Alternatively, the disks 10 can also have different diameters.
  • the disks of adjacent shafts can be aligned with each other be arranged, but can also be transverse to the conveying direction be arranged offset to each other, whereby a Traces of the scattered fleece is avoided.
  • the axially spaced disks 10 are each divided into V-shaped chambers 12 by blade elements 11.
  • the blade elements 11 are in a first Embodiment executed as rectangular sheets that the connect axially adjacent disks 10 and proceed from the surface of the rotating shafts 9 tangential to Extend the outer diameter of the disc 10 out.
  • illustrated embodiment are four blade elements 11 evenly distributed over the circumference of the rotary shaft 9 arranged so that between axially adjacent disks 10 four chambers 12 each are formed.
  • the neighboring ones Sheets 11 have an angle ⁇ of 90 ° to one another on.
  • the blade elements designed as sheets 11 can be of this type be designed so that they are compared to the outer diameter of the Discs 10 flush, protruding or recessed are.
  • the chamber rollers 7 also be arranged in such a way that the disks 10 of the opposite rotating shafts 9 in the middle of each Intervene slightly overlapping spaces. At this The arrangement of the blade elements 11 is recessed executed.
  • the wood chips of the material flow can be due to the arrangement the discs 10 whose axial distance is less than that Length A of the wood chips is not oriented transversely into the between the Discs 10 formed chambers 12 fall into it.
  • the wood chips that do not fall directly into a chamber 12 are due to the rotary movements of the chamber rollers 7 in Movement moves and change their orientation until they are oriented approximately longitudinally and into the Chamber 12 fall.
  • 3a shows how the wood chips (by way of example shown on a chip) in the slots between adjacent ones Slices 10 can fall into a chamber K.
  • the wood chip falls e.g. with the Front (B x C) down first and meets that first turning down towards the forming belt 6 towards the front pointing blade element 11 of a chamber 12.
  • the wood chips tip onto the sheet metal Blade element 11 (Fig. 3c). You lay down flat the sheets 11.
  • the wood chips can now only be turned slightly the chamber 12, insofar as this is the difference between Wood particle width and chamber width still allowed.
  • the blade elements are formed in a V-shape with a longitudinal kink.
  • the Blade elements 11 are arranged such that the Longitudinal edge 13 of the kink forms the highest point and the side elements slope down to the disks 10. This ensures that the wood particles depending on Center of gravity to the left or right to one of the two Disc 10 slides and with its side on the disc Facility is coming. This will also be the last degree of freedom taken and the wood particle is now in all three axes defined in chamber 12.
  • the blade elements always extend from an inner point P1, the first one running through the center of the roller radial line L1 lies to an external point P2 the disc that runs on one through the center of the roller extending second radial line L2, which is in a preferred embodiment in the direction of rotation of the behind the first line. Due to the location of the end points P1 / P2 and the shape of the blade elements between the end points P1 / P2 can be the point at which the wood chips from the Sliding blade elements can be varied.
  • a height adjustment of the Orientation unit 5 is provided.
  • the distance between the orientation unit 5 and the forming belt 6 must be in Dependence on the wood chips to be scattered in any case be adjusted so that when the wood chips slide down the chambers 12 the wood chips when they hit the forming belt rest with their rear edges on the sheets 11.
