Definitions

  • the invention relates to a method according to the preamble of claim 1 and a device according to the preamble of claim 3.
  • the starting mixture from a dosing hopper falls through the upper run and the lower run at one end of an endless, revolving driving belt onto a first, oscillatingly movable sieve element with a small sieve width.
  • the driver belt is provided with driver elements arranged at a distance from one another in its direction of rotation.
  • Driver elements of the lower run scrape over the first screen element and a subsequent second screen element with a larger screen width.
  • Coarse material that does not pass through the second screen element falls from the rear end of the second screen element onto a conveyor belt.
  • Each sieve element allows a fraction mixture to pass through, which inhomogeneously falls directly onto the mold base or the resulting fleece in such a way that initially finer and later increasingly coarser particles of the fraction mixture are scattered. This leads to an undesirable concentration of fine particles in the cover layers, which are later lost when the sheets made from the fleece are sanded.
  • a chain belt loading for a mixer is known per se from Fig. 63.
  • a chip mix is thrown through the upper and lower runs of the chain belt onto the bottom of a loading housing.
  • the chain belt is provided with driver elements for the chip mixture which are arranged at a distance from one another in its circumferential direction.
  • Driver elements of the lower run scrape across the floor to its rear edge, through which the chip mix is thrown directly into the mixer.
  • the invention has for its object to improve the shaping of the fleece.
  • this object is achieved by the features of claim 1.
  • Glue is preferably used as a binder for the particles, in particular chips, in a manner known per se.
  • the fleece is then fed to a press and pressed into a plate-shaped workpiece.
  • the cover layers on this workpiece have a comparatively high density because of the relatively small particles arranged therein. These cover layers are usually sanded smooth afterwards.
  • this grinding process according to the invention, only comparatively small portions of the finest particles are removed. This is achieved by applying the last, on average finest, fraction mixture as a homogenized top layer of the finest and somewhat coarser particles. at only the outermost part of this last layer is removed from the grinding process mentioned.
  • the particular advantage here is that the surface of the plate produced by grinding contains significantly more fines than in the prior art. This desirably results in higher density and less roughness on the outer surface of the plate created by grinding. Similar advantages result according to the invention for the middle layer, because not only the largest particles but also a homogeneous fraction mixture of these largest particles with smaller particles is present there. As a result, the transverse tensile strength of the plate is increased in a favorable manner.
  • Another advantage of the method according to the invention is that the disadvantages of so-called dust spots on the fleece are avoided. Such dust spots have hitherto arisen from the fact that lumps of dust that form somewhere in the device over time suddenly fall down in an uncontrolled manner and reach the fleece.
  • the fleece as a whole is scattered from the lower cover layer to the middle of the middle layer by a first molding machine and from the middle of the middle layer to the upper cover layer by a second molding machine which is mirror-image to the first molding machine.
  • each group can e.g. have three or four rollers.
  • the surface of each roller can be designed in a suitable manner known per se. Rollers of the same diameter, which are driven at the same angular velocity, are preferably used in each group. The angular velocity is preferably infinitely adjustable. The load on the rollers with the respective fraction mixture can thus be controlled.
  • the rotational speed of the driving belt is preferably infinitely adjustable.
  • Each sieve element preferably has a constant sieve width.
  • the arrangement of the sieve elements below the upper run saves construction height, reduces the fall height and prevents dust formation and segregation of the franking mixtures.
  • the driver elements of the active strand preferably come into scraping contact with the screen elements or form a small gap with them.
  • the sieving effect is improved and a contribution to the self-cleaning of the sieves is made.
  • the screen elements can preferably be moved in an oscillating manner in and against the direction of movement of the active strand.
  • the features of claim 9 prevent dust formation, concentrate the respective fraction mixture and facilitate its task on the downstream roller group. With the features of claim 9, an uncontrolled sieving due to the energy inherent in the falling starting mixture can be prevented.
  • the collecting plate can oscillate with the sieve elements.
  • the features of claim 11 lead to a space-saving arrangement of the discharge conveyor, which is e.g. can be a screw conveyor.
  • the arrangement according to claim 12 is particularly space-saving.
  • two fraction mixtures are generated with little structural effort.
  • the driver elements of the active run can come into contact with the screen or can be guided at a short distance from the screen. This relative setting is selected depending on whether or not scraping the driver elements over the sieve is necessary to keep the sieve openings free.
  • the screen can be driven in particular in and against the direction of movement of the active strand.
  • the features of claim 15 lead to a structurally simple and space-saving fractionation device.
  • the transport rollers can come into contact with the screen or be kept at a short distance from the screen. This depends on whether, in addition to the transport effect of the transport rollers, it is also desired that they should have a special cleaning effect on the screen.
  • the features of claim 17 offer a structurally simple and yet very effective fractionation device.
  • the lifting walls can be raised and lowered alternately or all at the same time.
  • the control of the lifting walls can also be done in such a way that they remain in their lowest position for a relatively long time. In this lowest position, the lifting walls can be in contact with the screen or can be kept at a small distance from the screen.
  • the desired two fraction mixtures can be obtained with little structural effort.
  • the features of claim 18 are used to collect and forward the fraction mixtures.
  • the feed of the starting mixture into the fractionation device is improved.
  • the features of claim 20 offer a very powerful fractionation device for two fraction mixtures.
  • the circumference of the circumferential pockets can be in contact with the screen or can be kept at a short distance from the screen.
  • the peripheral pockets can be formed in a particularly simple and stable manner.
  • FIG. 2 shows a diagram relating to the layer structure of the nonwoven according to FIG. 1,
  • Fig. 6 is a schematic section through yet another embodiment of the device.
  • FIG. 1 shows a device 1 for the continuous production of a nonwoven 2 from glued, fibrous particles 3, in particular chips, of different sizes.
  • An initial mixture 4 of the particles is fed into a dosing bunker 5 and distributed by a group of rotating rake scrapers 6 to form a layer 7 on the upper run 8 of a dosing belt 9.
  • the upper run 8 moves continuously in the direction of an arrow 10 and guides the layer 7 through a weighing unit 11, which measures the weight of the layer 7 over its entire width.
  • the weighing signals can be used in a manner known per se to control and regulate the manufacturing process for the fleece 2.
  • the starting mixture 4 is continuously discharged between the metering belt 9 and a discharge roller 12.
  • the starting mixture 4 falls through an upper run 13 of an endless carrier belt 14 onto an imperforate collecting plate 15 which is fastened to a sieve frame 16.
  • the driver belt 14 runs in the direction of the arrow and has driver elements 17 which are arranged at a distance from one another in its direction of rotation.

Abstract

La présente invention concerne un procédé et un dispositif de production d'un non-tissé. Selon ce procédé, un mélange initial (4), constitué de particules (3) de tailles différentes, est projeté, de manière dosée, à travers un brin supérieur (13) d'une bande d'entraînement (14), sur une plaque de réception (15). Cette plaque de réception (15) oscille (28) conjointement avec des éléments filtre (18, 19, 20). Chaque élément filtre laisse passer un mélange de fractions (22, 23, 24) qui traverse le brin inférieur (26) de la bande d'entraînement (14) et tombe sur une unité d'homogénéisation associée (35, 36, 37). Le mélange de fractions y est alors agité et homogénéisé. Le mélange de fractions homogénéisé est divisé en flux partiels (45, 46, 47) au moyen de groupes de cylindres (42, 43, 44) des unités d'homogénéisation, ces flux partiels étant dispersés les uns après les autres sur le non-tissé en formation (2).
