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.
- the pre-dissolving rollers are already in the spreading station and distribute the scattering particles according to their rotation in the direction of the arrow, in Longitudinal direction of the spreading station 4.
- a number of spreading rollers 11 is shown below the pre-dissolving rollers 10, of which only the first and last of the spreading rollers with the Reference number 11 was designated.
- the rest are in the exemplary embodiment 10 spreader rollers 11 which are like the first and last spreader rollers 11 in Turn clockwise, not for the sake of clarity with the reference symbols 11, at the end of this row of spreader rollers 11, which also To extend over the entire width of the base 5 is one Return screw 12 arranged, which serves to scatter particles, which due to their size, not through the spreading rollers during the conveyor spreading process 11 could be led through, to catch and over suitable Return lines to bunker 1 or faulty material, for example lumps of glue to convey out of the conveyor spreading process in order to to be excreted via the return screw 12.
- all 12 spreader rollers 11 rotate in the same Direction, i.e. in a clockwise direction. However, it is also possible that the spreader rollers 11 rotate in total in the opposite direction. This then requires that the return screw 12 on the other End of the spreader rollers 11 is arranged in order to avoid that defective goods on the pad 5 is applied to form the fleece 6, and thus the outermost layer of the fleece to be pressed is adversely affected.
- rollers 11 each have different speeds have to either the promotion of the accelerating particle flow to a fleece to a to achieve higher throughput by the spreader rollers 11, or at one Reduction of the speed of the individual spreading rollers at one smaller amount of scattering particles 2 also a smooth passage of to be scattered particles 2 by the spreading rollers 11 for to produce a uniform chip fleece.
- FIG 2 is a development 13 of the jacket of spreader roller sleeves 14, 15, as can be seen on the developments 13, are about the scope the spreader roller sleeves 14, 15 have channel-shaped depressions 16 of equal length or 17 is provided, each for the length of the spreader roller sleeve Levels 18 form and each channel-shaped recess 16 of one level 18 with each channel-shaped recess 17 of the other tier 18 with their channel axes 19 and 20 enclose an angle, which in the exemplary embodiment greater than 90 degrees with respect to a spreader roller axis 21 (compare, for example Figure 4).
- the control roller sleeves 14, 15 have a certain length and thus it can by lining up several such spreader roller sleeves 14, 15 one Spreading roller can be obtained in which the connection between the individual Sleeves 14, 15 via positioning and locking pins 22 (see also for example Figure 4), so that only the two outermost Spreading roller sleeves 14, 15 (see FIG. 4) bearing axles 23, 24 are arranged need to be the individual from spreader roller sleeves 14, 15 for example consisting of spreader roller 11 in a storage, not shown to be stored within the spreading station 4.
- Figure 1 displayed here can all spreader rollers 11 in one; Roller mill 25 shown here be arranged.
- the roller mill 25 itself can be raised and lowered (not shown) or tiltable to the base 5 (also not shown) be arranged.
- roller mill 25 By lifting or lowering and / or tilting the Roller mill 25 to the base 5 can be the scattering path between the exit plane from the channel-shaped recesses 16 and 17 from all floors at the specified amount and also depending on the increase in the amount to be pressed Fleece arranged above the fleece under construction become. This ensures that no change in the spread of the serving as a buffer channel-shaped depressions up to Hitting on the pad 5 or hitting the already in Realized nonwoven layer takes place.
- FIG. 3a shows an enlarged section from the development 13 according to FIG 2 was chosen to clarify that between the channel-shaped Wells 16 and 17 floor webs 27 and 28 are provided, and also webs 29 are provided between the channel-shaped depressions 16 and 17, which extend over the entire length of the spreader roller sleeves 14, 15.
- 3b shows a section along a channel-shaped depression 16, as can be seen from this, the ends of the channel base 30 are semicircular 31 led to the jacket 32 of the spreader roller 11.
- 3c which shows a section according to B-B according to FIG. 3a, it can be seen that the channel-shaped depressions 16 and 17 are semicircular are formed, and that the respective channel base 30 a distance 33 to the surface of the surface of the spreader roller 11. The same distance 33 also has the channel base 30 from the jacket surface 32 of the spreader roller 11th
- the spreader rollers 11 are downstream with each increasing channel-shaped Wells equipped, so it can be easily seen that thereby a significantly higher throughput of scattering particles through the adjoining spreading rollers can be enforced without a Clogging or jamming when the scattering particles pass through the Spreading rollers 11 can occur.
- the largest channel-shaped depression is here always chosen smaller than the parts that are not stored, the are discharged via the return screw 12. Such a size determination can be realized in that, according to the smooth surface of all spreading rollers 11 a determination of the largest still to be let through Particle can be determined.
- the spreader rollers close 11 are close to each other and occurring abutting edges 35 and 36, respectively staggered over the length of the spreader rollers 11 to each other. So that is excluded that scattering errors can occur due to these abutting edges.
- the abutting edges 35 and 36 in one plane can also spiral abutting edges between the individual spreader roller sleeves 14, 15, 35 can be used.
- FIG. 4 also shows, when using two spreader roller sleeves 14 and 15 the abutting edge of these two spreader roller sleeves arranged outside the center.
- Such a combination is different long spreader roller sleeves 14, 15 for producing a spreader roller 11 suitable the deflection of a non-spreader roller sleeves Reduce spreading roller.
