Definitions

  • the invention relates to a spreading head of a scattering system for at least partially producing a spreading material mat according to the preamble of claim 1 and to a method for producing a spreading material mat in the course of the production of material plates according to the preamble of claim 6.
  • a mixture of particles or fibrous materials and a binder is scattered to a grit mat on a forming or conveyor belt, the grit mat is then fed to any necessary pretreatment and finally a compression.
  • the compression can be carried out continuously or discontinuously by means of pressure and / or heat.
  • MDF boards consisting of medium density fibers or OSB plates from oriented scattered chips. Scattering occurs in one or more plies as needed, with the need for multiple plies typically occurring with thicker sheets or with multilayer sheets. But also in the thin plate production can be different layers be desired, especially if specially differentiated requirements between the middle layer and the outer layers exist.
  • a high throughput of grit and with an oriented scattering arise stray or other basis weight inaccuracies in a scattered Grit mat, which worsen the later quality of the material plate.
  • the transverse scattering to the production direction is problematic, since imprecise basis weight distributions are unavoidable, especially in the edge regions. Also effects on the surface area weight distribution far away from the longitudinal edges of the spreading material mat can not be completely eliminated.
  • the entire transverse orientation of the material to be spread with fan rollers of a transverse orientation device has an inaccuracy of only +/- 10% per scattering head. As a result, grit mats with a high proportion of transversely oriented layers have a high scattering inaccuracy.
  • a scattering head requires a minimum length for producing a sufficiently large scattering space above the scattering rolls, in which the spreading material can be optimally distributed and dissolved in order to achieve good values of a basis weight distribution.
  • the spreading material is sorted by size and / or density by means of a separating device, usually a roller scraping head or an air classifier, and deposited successively on a forming belt. As a rule, the fine grit is first on the Formed band deposited, then the coarser grit is scattered over the fines. This gives a grit mat containing a fine topcoat and a second coarser layer.
  • a coarse layer and / or a fine layer are sprinkled again. This results in a middle layer of similar coarse grit and two layers of fine grit.
  • systems for the production of oriented chipboard (OSB) work exactly opposite, because here the long chips are preferably laid longitudinally oriented on the forming belt as a cover layer and the shorter and broken chips are scattered in the middle layer oriented transversely.
  • the invention has for its object to provide a scattering head, with which a material plate of at least two different layers can be produced, with respect to the prior art in terms of simpler design now and the associated lower investment costs advantages are achievable. Furthermore, an improvement of the basis weight distributions overall in the grit mat is to be achieved by a method to be created and a grit mat that can be produced with it.
  • the solution for a scattering head is that for the scattering of the grit a transverse orientation device and / or a longitudinal orientation device are arranged together with a spoke scattering device in the production direction in any order on the forming belt.
  • the invention for the method in that the grit is oriented in the production direction in any order with a transverse orientation device and / or a longitudinal orientation device and scattered unoriented on the forming belt with a spreader spreader.
  • the neutral fiber of an OSB board should not necessarily be formed by an oriented scattered layer, but advantageously by an unoriented but very uniform layer.
  • spoke rollers as a storage and distribution device for the grit on a forming belt, it is now possible for only three scattered heads produce a three-layer oriented scattered material plate on the outside, depending on requirements and production request longitudinally or transversely scattered grit and in the Middle layer has an optimized with respect to the basis weight grit layer, which can optimally process in particular bending stresses by mutual loads in their middle layer without Show detachment phenomena.
  • the multi-axial orientation of the material to be spread in the middle layer and the additional portions of fines increase the rigidity and strength of the material plate.
  • a preferred five-layer material plate is produced from a grit mat which is spread out longitudinally, laterally in the following layer, unoriented in the middle and then again scattered transversely and outwardly in the direction of production. Overall, therefore, in the case of the material plates, an improvement in the transverse strength and in the thickness swelling occurs.
  • orientable grit in particular grit, which is used for the production of oriented scattered material plates
  • spokes directly on a forming belt.
  • the optimum straightening accuracy over the surface is based on the fact that the spoke rollers can optimally distribute the spreading material over a given area, which also applies in particular to orientable material.
  • the spoke spreading device in question consists of spoke rollers, which are also called cage rollers. These spoked rollers are commonly used for dissolving and distributing a grit stream before the grit is discharged from a bunker onto spreader rolls of the transverse or longitudinal orienting nature. This is for example in the US 5,662,227 A ( FIG. 2 ) already disclosed.
  • the cage rollers or similar constructions shown here are known to those skilled in the art.
  • the cage or spoke rollers consist of a width across the width of the forming belt centrally arranged roller, which has a disk on the outside, again at the periphery of the discs rods, wires, Pipes, or similar machine elements, are fixed, which are arranged parallel to the central rotating roller.
  • the individual spreaders are arranged in a predetermined order.
  • the spreaders are in a plane and / or at the same distance from the forming belt.
  • the common feature is that the longitudinal orientation, the transverse orientation and the spreader device should be the closest to the forming belt scattering and storage device.
  • a term suitable for this would be arranged directly above the forming belt. Any necessary dissolution device would thus be arranged in the direction of the scattering material above the scattering devices, but may for example in addition to the known spiked or pin rollers also consist of an array of spoke rollers, which dissolve the grit before hitting the scatterers.
  • two scattering heads of the type according to the invention are used, which are arranged mirror-inverted in the direction of production.
  • FIG. 1 shows a schematic and lateral sectional view of a scattering head 1 according to the invention and a circulating in the production direction 13 below the scattering head 1 forming belt 8 for transporting the part formed by the scattering head 1 or independent grit 7.
  • the grit material 7 is omitted due to the clarity on it with different Patterns or shades of gray for each layer. Instead, there are indications of different spreaders, which store a predetermined amount of grit 3 on the forming belt 8 in their own area.
  • the grit 3 is entered in the illustrated scattering head 1 by means of a dosing devices not shown in detail (grit hopper with discharge or the like).
  • the task angle in the scattering head 1 is usually controlled by a task flap 16, which at the same time also assumes a task function of the scattering material 3 on an optional opening device 11.
  • the opening device 11 is preferably made of spiked rollers 9, depending on the application in different sizes or features of the spines.
  • the dissolving device 11 causes a large-area distribution of the material to be spread 3 in the spreading head 1, in particular a separation 20 (shown schematically below the forming belt) of the material to be spread 3 in a coarser fraction G and a finer fraction F over the length (in the production direction 13) of the Litter Head 1.
  • FIG. 2 shows a Doppelkopfstreustrom 17 for producing a three-layer grit mat 7 by means of two mirror image mutually arranged scattering heads 1.
  • the separation 20 of the two scattering heads 1 is also in the production direction 13 also arranged opposite to each other, so that after formation of a cover layer of transverse scattered scattered material 3 by means of a Transverse orientation device a two-fold scattering of unoriented grit 3 from the two spoke scattering devices of the two scattering heads 1 connects.
  • This twofold scattering effects a homogeneous layer of unoriented spreading material 3, which in turn is covered in the production direction (on the outlet side of the left scattering head 1) with a transversely oriented layer of spreading material 3, which ultimately results in the production of a three-layer spreading material mat composed of two oriented and one unoriented layer.
  • FIG. 3 is an expanded embodiment of a possible scattering head 1 with three arranged in series different scattering devices, wherein in Production direction 13 is first a longitudinal orientation device 15 with disk rollers 5, a transverse orientation device 12 with fan rollers 2 and the output side a spreader device 14 with spoke rollers 4 is arranged. Again, the grit 3 is first separated after the task in the scattering head 3, so that there is a separation in the production direction 13 from coarse G to fine F and thus predominantly the coarse grit 3 on the longitudinal orientation device 15 and the fine grit 3 on the spoke scattering device 14 arrived. Depending on the setting or effect of the opening device 11, a corresponding proportion of spreading material 3 results, which is dispensed with the transverse orientation device 12 arranged in the middle.
  • FIG. 4 becomes with the mirror image arrangement of two scattering heads 1 after FIG. 3 a Doppelkopfstreustrom 18 for producing a five-layer grit mat 7 shown.
  • a longitudinally oriented layer of coarse spreading material 1 on the forming belt 8 is first applied from the right scattering head 1, followed by a transverse layer and an unoriented layer, on the output side of scattering head 1 on the right side.
  • the scattering head 1 is again an unoriented layer of grit 3, then again a cross-oriented and finally again a longitudinally oriented layer.
  • FIG. 5 shows a four-head litter 19 for producing a five-layer grit mat 7.
  • the outside two pure scatter heads 1 are shown to form a longitudinally oriented layer.
  • This arrangement is particularly advantageous in the production of container plates with a long spreading material (over 150 mm in length) on the outer layers.
  • the spreading material is subjected to a separation 20 in these pure scattering heads 1 for longitudinal orientation.
  • the two inner and in turn mirror images of each other arranged scattering heads 1 are like the scattering head after FIG. 1 executed and form three layers (transverse and unoriented) of the grit mat.
  • FIG. 6 shows the schematic structure of a five-layer grit mat with two outer longitudinally oriented layers 21, two underlying transverse oriented layers 22 and a middle unoriented layer 23rd LIST OF REFERENCE NUMBERS 1.
