Definitions
- the invention relates to a method for forming a grit mat from grit, wherein the grit consists of wood fibers, wood chips or the like particles in the course of the production of wood-based panels by means of pressure and heat in pressing according to the preamble of claim 1. It further relates to a forming station for carrying out the method according to the preamble of claim 9.
- 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 heat.
- the usual material plates that are produced in this case are usually MDF boards, consisting of medium density fibers or OSB boards oriented scattered chips or shavings. Scattering occurs in one or more plies as needed, with the need for multiple plies typically occurring on thicker plaques.
- the main problem is that the material throughput for a scatter of 10 mm is quite different from that at 1200 mm height of a grit mat. But due to the arrangement of up to fifty parallel mutually arranged scattering rollers for the production of thick grit mats of a height of up to 1,000 mm thick or sticking faulty runs in the scattering of thin grit mats up to 150 mm over at least twenty scattering rollers until it reaches the separator , This fact arises because the scattering material has already been completely scattered in the first third of the arranged scattering rollers due to the small amount of spreading material.
- the rotating spreader rolls are usually provided with a variable number of elevations or spines, the actually too thick faulty material can either slip out of a coincidence even through a gap or it is possibly split or crushed and can then reach the grit mat. In case of a fragmentation of the defective goods, however, the parts fall promptly and in the immediate vicinity through the spreading gap. If this faulty material, usually fiber agglomerations, a size of a 1 cent piece to a size of a 2 euro coin or just before transfer to a precipitation device but still on an already finished and actually homogenized grit mat, here form differences in basis weight differences in the finished Show end product as partial darkening or cloudiness.
- opening rollers may be arranged in the discharge chute to allow optimum dissolution of the material to be spread before hitting the roll carpet.
- the high rotational speed of the opening rollers at several hundred revolutions per minute results in massive air turbulences in the falling spreading material, which extend approximately within a radius of up to one meter from falling falling material flow. If the grit is scattered directly under the task area or the discharge chute through the spreader rolls on the forming belt this is problematic because the already occurred irregularities and the air turbulence are simply passed through.
- the roll carpet is usually adjusted in height in the state of the art for adjusting the scattering height (distance between roll carpet and forming strip) with scattering material mats to be scattered at different heights.
- the system parts arranged above the roll carpet must also be used mitver Lucas be, which has the consequence that an immense plant technical effort must operate in order to arrange the scattering head, the grit bunker and possibly also the spreader supply to the grit hopper height adjustable in the system.
- a simple height adjustment of the forming belt is usually not practical, since a once scattered grit mat sensitive to non-linearly running mold belts and challenge damaged or internally deformed grit mat a reduction in quality.
- the invention has for its object to provide a method by which it is possible to optimize the production of material plates in terms of surface quality and plate properties by the scattering of a grit mat is optimized before compression in terms of their homogeneity and dust content of the grit evenly into the Spreader mat be introduced. Furthermore, an associated forming station for carrying out the method is specified, which also offers the possibility of optimally scattering differently high spreading material mats in addition to the previous advantages, in conjunction with a minimum of system complexity.
- the solution for a forming station is that to form two different areas of the roll carpet differently designed leveling and scattering rolls are arranged, wherein in the production direction of the roll carpet leveling rolls in a leveling Egalisierberelch to a length of 1 to 4 m and then scattering rolls in a scattering area on a Length of 0.5 to 8 m are arranged.
- Fiber board production not only uses fibers up to 3 mm in length, but also has a relatively high dust content with a fiber size below 0.1 mm. It is a small one Advantage in the use of mixed wood as a basis for the production of material boards that softwood compared to hardwood and annual plants has a lower dust content.
- the dust content usually falls immediately at the first scattering rollers with through on the forming belt, so that sets in terms of dust content, a strong inhomogeneity on the height of the grit mat.
- the present invention is advantageous in that no significant amount of dust or material falls on the forming belt due to the leveling path, and the dust content remains mixed in the spreading material during the transport on the leveling rollers. From the spreading rollers, the spreading material begins to fall evenly on the forming belt, whereby a homogenous spreading material mat is set with regard to the dust content over the height. Accordingly, a teaching of the invention is that in the scattering area the spreader rollers spikes or surveys and at the same time have a large distance to scatter optimally evenly over a short scattering distance and to classify the grit to avoid with the exception that grit with oversize still not is scattered.
- the roll carpet is preferably raised at the end of the scattering range so that at higher scattering material to be scattered mats always an optimal distance of about 200 mm Scattering height is set, which is understood by scattering height of the distance of the lower edge of the scattering roller to the already existing mat surface. Since a linear throughput of grit results over the scattering range, there is also a linearly increasing grit mat in the production direction.
- the teaching of the invention becomes even clearer, since the Egalisier Scheme at an angular position of the roll carpet at the same time as a conveyor to overcome a height difference (measured from the first leveling roller to the first scattering roller) for scattering high spreading mats and thus the optimal adjustment of the scattering height in the scattering area is possible with simultaneous application of an increased distance between the spreader rollers and the use of a small number of spikes on the spreader rollers themselves. Because by the massive increase in the spread rate per unit length to be scattered grit mat grows above average.
- the advantage of the invention over the prior art with uniform scattering rollers is also that, especially in the scattering of grit mats for the production of thin material plates of the fiber stream is leveled on the leveling rolls from below. As a result, a fiber stream is transferred to the scattering area which can be designated in the production direction as homogeneous in terms of basis weight. Thus, the basis weight distribution transversely and longitudinally and at a short distance measured on thin plates was significantly improved and a cloudy plate surface of the final product could be avoided.
- the equalization of the material to be spread in the Egalisier Symposium from below is created by the constant moving up and down on the leveling rollers where viewed in the production direction areas of the Spreading material with too many fibers in adjacent areas with fewer fibers are distributed. Clarified in a wave crest (range of too many fibers) by the approaching approximate shaking movement, a broadening of the wave crest takes place and thus an approximation to optimal conditions.
- FIG. 1 a schematic side view of a forming station 1 with the associated grit hopper 13 (schematically) and disposed therebetween discharge chute 3, wherein the discharge rollers 17 of a discharge of the grit hopper 13 for a continuous supply of material of the material to be scattered 2.
- the grit 2 at the end of Abschachtes 3 in Egalisier Scheme 8 falls on the leveling rollers 15 and is transported without appreciable scattering effect in the direction of production 10.
- the scattering area 9 sets only with the scattering rollers 16 a scattering of the grit 2 and later in this case arises on the forming belt 6, the grit 7.
- the horizontally arranged forming belt 6 then usually conveys the spreading material mat 7 through a pre-press (not shown) and then the spreading material mat 7 becomes a continuously working one Double belt press (not shown), a calender press (not shown) or split a cycle press for pressing and curing passed.
- a separation device 4 is provided which rejects oversized spreading material or for other reasons unusable spreading material from the production process.
- FIG. 2 is opposite FIG. 1 a forming station 1 shown, in which case in a preferred embodiment, the roll carpet 14 at an angle ⁇ to the forming belt 6 by means of actuators 5 (only schematically indicated) is employed.
- the leveling rollers 15 are arranged in the production direction 10 in the leveling area 8 and / or the scattering rollers 16 in the spreading area 9 at an angle ⁇ of 0 to 30 ° to the forming belt 6 rising.
- the leveling rollers 15 in the production direction 10 in Egalisier Scheme 8 parallel to the forming belt 6 and only the scattering rollers 16 at an angle ⁇ of 0 ° to 30 ° to the forming belt 6 may be arranged rising.
- FIG. 4 finally clarifies the transport principle of the leveling rollers 15 in wordsschtung 10, wherein the leveling rollers 15 to each other have the same direction of rotation 12 and in equalizing 8 no significant amount of grit 2 to fall down through.
- a homogenization of the grit 2 conveyed via the leveling rollers 15 is performed by increasingly flattening a crest 18 of the grit 2 in the conveying direction, producing flattened crests 18 ', 18 " distributed and virtually dissolved.
- FIGS. 5 to 7 illustrate in particular the individual parameters of the established design rule for the optimal leveling or scattering of the material to be spread 2 in the production of MDF boards.
- the distances X of the core diameter K of the leveling rolls 15 in the leveling area 8 should be 10 to 25 mm and the distances Y of the core diameter K of the scattering rolls 16 in the scattering area 9 should be 30 to 100 mm.
- the distances X of the core diameter K of the leveling rollers 15 are identical to each other in the equalizing region 8 and the distances Y of the scattering rollers 16 in the spreading area 9 in the production direction 10 are continuously increased to a maximum distance.
- the spikes 11 should have a length S of 10 to 25 mm on the leveling rolls 15 and a length S of 10 to 50 mm on the scattering rolls 16.
- 20 to 40 spines 11 and on the spreader rollers 16 are preferably arranged over the circumference of 5 to 10 spikes 11 over the circumference of the leveling rollers 15.
- the spikes 11 are preferably arranged at a distance V of 7 to 13 mm and on the spreader rollers 16 over the length L at a distance W of 20 to 60 mm.
- the spines 11 can be performed as nails or pins, which are tapered at the end. They can also be cut out of a rotating disk by means of laser beam machining or machining manufacturing method or punched out non-chipping. Also, a purely cylindrical shape of the spikes 11 is conceivable.
- the material is preferably plastic or metal use.
- the molding station described can be used to carry out the method, but can also be used as an independent molding station with its features and does not depend on the method.
