Definitions

  • the invention relates to a process for continuous production a continuous fleece made of stored particles different dimensions by means of conveyor spreading process for a production of wood-based panels or similar panels by subsequently pressing the fleece.
  • EP 0 626 241 A1 describes a method and a device for evenly distributing pourable material on one known moving in a conveying direction.
  • the equalization facility consists of several transport elements arranged one behind the other in the transport direction, between which partial flows of the material the entire spread is dissipated to the base.
  • a device has become known from German Auslegeschrift 1205274 in the by means of wood chips or similar sprinkled Paricle is formed on a strand carrier (forming tape), that gets into a press continuously or in sections produces solid moldings, in particular chipboard, in which the Scatter particles are oriented in different directions, whereby then either by way of the scattering particles from the litter to the strand carrier one or more swing frames or one or more special throwing rollers, or one or more whirlwind nozzles, or a combination of these or equivalent devices are provided, via or on which past the scattering particles coming from the litter for orientation in have to go in substantially different directions.
  • the present invention is based on the object regardless of the speed of the spreading rollers for the conveyor spreading process to have a well-defined discharge level for the litter, so not only no missing particles get into the scatter, but also one over the total scatter uniform build-up of those passing through the rollers Particle is reached. By defining a distance between the scattering level and the fleece level there will still be incorrect scattering counteracted.
  • This object is achieved according to claim 1 in that during the conveyor spreading process initially intentionally continuously over the entire spread and the spreading length of the conveyor spreading process formed intermediate stocks from which individual scattering processes for continuous formation of the continuous fleece. This ensures that both the distance between the start of spreading and the spreading of the spreading material is very well defined in the fleece, and that on the other hand depending on the Intermediate stocks practically the same amount of particle stream to be scattered is spread over the entire conveyor spreading process.
  • An embodiment according to claim 3 of the inventive method exists in the fact that the deliberate formation of the intermediate stocks over the spread the conveyor spreading process is controllable. By this control lets the density and thus the strength also in the transverse direction of the finished Affect wood-based panel, so that in the end a wood-based panel can be generated in both the longitudinal and transverse directions predetermined strength properties can be generated.
  • An embodiment of the method according to claim 4 is according to claim 5 according to the invention protected in such a way that the discharged particles be re-shredded, at the end of which can be used Particles are recycled, and unusable particles are excreted become. On the one hand, this results in a reduction in the amount to be eliminated Materials achieved and beyond a recycling of such Material allows, for example when using wood, which a very small thickness, but a considerable one in the other dimensions Has area extension.
  • Protection is provided that depending on the scattering of the intended particles and depending on the formation of the continuous fleece by means of a conveyor spreading process, a preselectable separation of the particles takes place. Alone through the pre-selectable separation of the particles depending on the connection of the particle flow and the throughput through the conveying process predeterminable cross-sectional profiles through the thickness of the fleece.
  • each spreader roller alternate in the circumferential direction several floors, first equally long, channel-shaped depressions and offset several floors with second, equally long, channel-shaped depressions that each floor of the respective channel-shaped depressions by webs is separated from the next floor on the surface of the jacket, and that the respective first and second equally long, channel-shaped depressions in Axial direction of each spreader roller through webs over the entire length of the Shell surface of the spreader roller are separated so that each channel-shaped Depression represents a separate depression in the surface of
  • This device allows preselectable subsets from the litter particles emerging from the bunkers, and at the same time by the rotation of the row of spreader rollers a conveying process effect, with which the other, separate depressions of the spreader rollers be filled at the same time, so that with further rotation of the Spreading rollers a conveyor spreading process arises, in which essentially equal amounts of spreading material at the same time from the rotating Spreading rollers are released and put down on the continuously moving document are stored.
  • each spreader roller obliquely to their Axial arranged first, equally long channel-shaped depressions carries that offset several floors with second, channel-shaped channels of equal length Wells are provided, the channel axes of which are at an angle to the oblique Channel axes of the first, equally long channel-shaped depressions take in. Due to the arrangement of oblique to each other equally long, channel-shaped depressions, which do not, however, mutually rotate, is achieved according to the invention that in particular with directly with her Rotating spreader rollers in contact with one another crush or wedge litter before reaching channel-shaped Wells are avoided, and that the transport process over the entire arrangement of rotating rotating Spreading rollers run flawlessly. This will further improve it Intermediate storage in the channel-shaped depressions achieved, which then by turning the spreading rollers further, an exact spreading from these Permits intermediate bunkers on the underlying surface.
  • the angle between the first and second be of equal length is channel-shaped depressions greater than 0 degrees and less than 180 degrees.
  • Claim 10 proposed that the respective channel-shaped sections wear semicircular arches at the ends of the roller shell. Through the Arrangement of semicircular arches will get the scattering particles caught Filling and emptying the channel-shaped sections easier.
  • the channel-shaped sections starting from the roll jacket to the channel base perpendicular to the direction of the Channel axis are rounded.
  • This design of the channel also promotes both filling and emptying the channel-shaped sections; it also serves to squeeze conveyed on the spreading rollers Spreading particles to the next spreading rollers of the conveyor spreading device, which facilitates the spreading process.
  • channel-shaped sections according to the invention are rounded Wear cross sections. This configuration according to the invention helps to keep it clean of the channel-shaped sections.
  • each spreader roller from at least two in the axial direction roller sleeves arranged one behind the other with channel lengths of equal length There are depressions and that the webs over the entire length of the jacket Spreading roller have an uninterrupted course.
  • claim 14 Protection is sought for that visible between the spreader roller sleeves circumferential butt edge with at least two consecutively arranged Spreading rollers are not aligned with each other. This is achieved that there are no harmful influences from the abutting edges over the entire Run out row of rotating spreader rollers.
  • the measure to be protected according to claim 16 is that two sleeves an abutting edge between the sleeves, outside the Middle between the two roller surfaces, is arranged. This represents one represents particularly preferred embodiment of the subject of the invention, with regard to avoid the deflection of sleeve-shaped spreader rollers.
  • the distance (depth) between the surface of the spreader roll and channel bottom of the channel-shaped sections of Spreading roller to spreading roller have a different dimension. This enables that over the transport route, i.e. in the area of the conveyor spreading process, additional material in the channel-shaped sections of the downstream or upstream pairs of spreading rollers are temporarily stored can. On the one hand, this increases the throughput with the same spread quality such conveyor spreading increases, and on the other hand is an interference the spreading quality avoided.
  • the device protected in claim 18, which is also a Design of the device according to the invention also serves for Carrying out the method according to claims 1-6, if in claim 18 under Protection is provided that the distance (depth) between the surface of the spreader roller and channel bottom of the channel-shaped sections over the length of the individual spreader roller have different dimensions.
  • claim 20 a use of the hobbing process or the pressure or the injection molding process in the manufacture of the surfaces of the spreader rollers according to the claims 7-19 for performing the method according to one or more of the Claims 1-6 of the present invention are protected.
  • spreading rollers produced after use are distinguished characterized in that the surface of its shell is subsequently machined Processing process are subjected.
  • mechanical processing the surface of the jacket is achieved for the first time for a conveyor spreading process provided spreader rollers even when their roller jackets are in direct contact for the first time an unambiguous intermediate storage of what is required for scattering Enable particle flow.
  • this is for the first time thanks to the inventive rows of spreading rollers achieved with a smooth, breakthrough surface that well defined a stream consisting of particles of different dimensions, continuously a fleece is formed in which, depending on the direction of movement Document for the reception and / or the arrangement of the conveyor spreading process performing inventive arranged one behind the other Spreading rollers create a fleece over the base, the cross-section of the outer layer starting with fine particles up to a layer with coarser or coarse particles are continuously formed, and from here from in continuous training to the other outer layer of the Fleece runs with fine particles again.
  • litter particles 2 are stored in a bunker 1 a discharge 3 fed to a scattering station 4, the width of which is the width corresponds to a base 5 on which a chip fleece 6 is produced, which then continuously in a press station, not shown or is pressed discontinuously into wood-based panels.
