Definitions

  • the invention relates to a device for aligning and depositing elongated lignocellulose and / or provided with at least one binder cellulose-containing particles such as wood shavings, wood fibers or the like on a continuously moving pad to a fleece for the subsequent production of plates containing such a particle Dosing bunker, a unit for transferring the particles an orientation unit above a continuously moving one Underlay is arranged, the distance between the orientation unit and the continuously moving pad is higher than that Top of the fleece to be formed.
  • each guide surface protrudes in the same plane
  • a plurality of spaced apart projections, their thickness is equal to the thickness of the guide surface.
  • These tabs are as regular Quadrilaterals with two parallel edges and one on top, for Border edge parallel top edge and / or as triangles with an overhead Tip trained. What is achieved is that those particles the top edges of two or more moving guide surfaces span first, twisted in an arc and then aligned parallel to each other between the guide surfaces continuously moving pad fall, but there is at least the Risk of blockages and damage to the particles.
  • a differently designed device for aligning wooden particles (strands) across the width of a moving pad is from the German Laid-open publication 2,523,515. Belong to this facility a pre-orientation unit that has a plurality of upright ribs also has a drum with attached to its outer circumference Wooden strand orientation guide plates and a catching device, which the wooden strands between an arcuate casing and a plurality of spaces, each through the peripheral surface the drum and a pair of baffle surfaces, so long trapped until released at a predetermined location to be aligned parallel to each other on a moving surface to fall on which they lie across their direction of movement. The throughput and the degree of orientation of the particles are however not satisfactory.
  • the invention has for its object an alignment device trained in such a way that the degree of orientation of Particles with high throughput and without damage to the particles can be improved in trouble-free operation.
  • the orientation unit consists of several right angles to the direction of movement of the continuously moving pad in one spaced at least substantially horizontally and against the direction of motion continuously moving pad revolving fan rollers, the individual compartments delimiting Air-impermeable alignment surfaces at least in the area their free ends against the direction of movement of the continuously moving pad curved and / or angled are.
  • the figure shows a dosing hopper 1, which is carried out in a conventional manner can be and next to a bottom conveyor belt and Stripping rollers has a feed unit 2, by means of which the glued lignocellulosic and / or cellulosic elongated particles over pendulum flaps 3 an orientation unit enclosed in a housing 4 provided group of opening rollers 5 are supplied.
  • the opening rollers 5 extend across the width of a moving base 10, on which the respective fleece is formed.
  • a first group of Opening rollers 5 is counterclockwise and a second group in Driven clockwise so that the supplied via the feed unit 2 Particle material is evenly distributed and accordingly evenly meets a group of fan rollers 7, which below the Group of opening rollers 5 arranged and against the direction of movement the moving pad 10 are driven in rotation.
  • Between the opening rollers 5 and the fan rollers 7 are in relation to the Vertical inclined baffles 6 are provided, which ensure that the fan rollers 7 targeted in their upper area where the fans 9 open towards the opening rollers 5, be loaded.
  • the fan rollers 7 have a plurality of alignment surfaces 8, which are impermeable to air are executed and such a mutual distance have that only so much particulate matter in a compartment 9 can be that a complete alignment of the elongated particles can be guaranteed.
  • the alignment surfaces 8 are designed so that they are the recorded and due to the flat structure transverse to the direction of movement of the base 10 aligned elongated particles only then again from the compartments 9 give up when the fall of the particles between fan roller 7 and moving Base 10 or the base 10 formed on this moving base Fleece is minimized.
  • the alignment surfaces 8 are opposite to the direction of rotation of the fan roller 7 curved and / or at least in the region of their free ends angled. Depending on the practical circumstances, can the alignment surfaces are continuously curved, with towards the free end decreasing radius of curvature curved or only in the area the free ends can be curved. Instead of a continuous one Curvature can also be provided, the alignment surfaces 8 especially to fold several times, so that several levels, over kinks interconnected partial surfaces are present, which is a curved Approach the structure like a polygon.
  • the orientation unit 4 enclosed by a housing is preferred is adjustable in height with respect to the moving base 10, as indicated by double arrows.
  • the axes of each other Identical fan rollers 7 preferably lie in one plane, the one with the moving pad 10 the angle of rise of the on the Base 10 formed nonwoven at least substantially corresponding History.
