Definitions

the invention relates to a method for the complete or layered production of a grit mat from chips according to the preamble of claim 1 and a spreader for the complete or layered production of a grit mat from chips according to the preamble of claim 14.
the pressing force is transmitted by hydraulic actuators on the press and heating plates and further on steel belts, which are supported by a rolling element carpet (rolling rods) circumferentially arranged on the grit.
the steel strips with thicknesses of approximately 1.5 to 4 mm form the weakest component in the chain of failure-threatening machine elements compared to the other, substantially stiffer elements. In this context, it does not mean that the steel strip fails completely, but should the surface of the steel strip damage it already leads to a regularly occurring poor quality of the final product and thus to rejects.
Such gauges have basically proven in the matter, but are problematic especially in fast-running systems, since at a production speed of more than one meter per second, the continuously operating press must be brought to a halt so quickly in an emergency or rapid shutdown that the density increase does not enter the press nip during the braking process and can cause damage to the steel belts there. In general, this succeeds successfully, but puts an enormous burden on the brake system and many machine elements of the continuous press, because in addition to the rotating steel belts, the massive idler pulleys, the revolving roll bar carpet and a few more machine elements are brought to a standstill with the corresponding moment of inertia have to.
the spreading material is applied to a plurality of spreading rollers driven in the same direction, which at least in groups have the same center distance and can thus assume a classifying function.
it is also provided at the end of this scattering roller assembly to arrange a device that can eject erroneous grit from the grit stream from the scattering area.
it is known in this case to subject the grit before or after the scattering rollers of an air flow parallel to the Formbandraum. Due to this air flow, small and fine particles of spreading material are carried far and thus first of all reach the forming belt to form a cover layer of fine particles.
a scattering device can be arranged laterally reversed again, so that again a layer of heavier spreading material is applied to the already existing material of the spreading material mat and finally passes again a fine layer of cover layer particles on the now finished spreading material mat.
a multi-layer grit mat can be produced by simple means having different layers, preferably fine particles form the outer layers and the larger and coarser material the middle layer. Both systems and methods have been proven in principle and were designed at a time when still predominantly calendering presses were used for the production of thin plates and the double belt presses were used with stainless steel bands for the production of thicker chipboard.
the invention has for its object to provide a method and an apparatus for complete or layered production of a grit mat from chips, which ensures a sorting of oversized grit and / or glue lumps with the same outstanding outstanding quality over the length and width of the forming belt, so In the grit mat to be produced no density peaks with possible consequential damage to the press used can occur.
the secondary screening is carried out by means of a perforated plate or a wire mesh, which may preferably be subjected to a continuous but also a regularly occurring vibration.
the second screening can also be performed with a roller screen and air classification can with several Fugspansieben be carried out, wherein preferably the following Flugspansiebe have a stronger effect than the first flowed through.
the air flow is directed parallel to the forming belt and can be controlled by the height of the windbreak chamber in intensity and volume.
the air flow is supported at the end of the windbreak chamber with a suction and there should be a separator for particulate matter there.
FIG 1 there is the schematic structure of a spreader 1 with a Windstreusch 13.
a grit bunker (not shown).
the grit is controlled introduced into the grit entry 3 of the spreader and fed by a baffle 2 a roller screen 5 above the windbreak chamber 13.
the roller screen 5 consists of mutually parallel rollers, which define by their distance from each other a gap size through which the grit 4 can pass through.
the rollers can be made smooth or have a special surface pattern.
the roller screen 5 is associated with a discharge device 11 for oversized spreading material 15 in order to remove this spreading material 15 from the scattering process.
the grit 4 hits a present in the wind striker 13 and directed air flow 10.
the lighter and thus generally smaller particles are guided by the air flow 10 through the windbreak chamber 13 and land in this embodiment, first on the forming belt 14, which rotates with the direction 22.
a first air classification of the material to be spread takes place by means of an oblique flight plane screen 7, which is thus arranged obliquely in relation to the air stream 10.
the wind-ratchet chamber 13 can be brought about by a blower (not shown) and / or by a suction (not shown) and is regulated in accordance with the spreading material and throughput.
a perforated plate or a wire mesh screen is arranged as a second screen 6, that is usually arranged at an angle of 5 - 10 ° to the forming belt.
the wire mesh screen can be designed with a hole spacing of 5 mm ⁇ 5 mm or 10 mm ⁇ 10 mm.
the flight saw screens 7, 8 and / or the second screen 6 (if not provided with rotating elements) is provided with a vibration drive 16 to increase the conveying effect in the direction of the discharge devices for oversized grit.
a vibration drive 16 to increase the conveying effect in the direction of the discharge devices for oversized grit.
the flying sifting 7, 8, 8 '.... and / or the second sieve 6 from the spreader laterally movable out, depending on the capacity of the system even in direct exchange with just maintained sieves.
FIG. 2 is shown as a further embodiment, while under the roller screen 5, one or more opening rollers may be arranged, which are preferably designed as a spoke rollers 17 with a diameter of more than 450 mm.
the spokes 18 may, as shown in left in spoked roller 1.7, be arranged on the outside or, as in the right spoked roller 17 in the manner of a spiral pattern from the inside out several times.
the direction of rotation 21 shows for overhead oversized grit on the discharge 12..
FIG. 3 shows how two scattering machines 1, 1 'according to FIG. 1 or 2 are arranged so as to be mirror images of one another, so that a spreading material mat 9 with two outer layers or outer layers is formed.
This system works in such a way that on the forming belt 14 first a covering layer 26 with a very thin spreading material and then a middle layer 25 with the remaining spreading material from spreading machine 1 is formed.
the downstream mirror-image standing spreader 1 'places on the existing layers (cover layer 26 and middle layer 25) of the grit 9 again a normal grit for the middle layer 24 and then finally again a cover layer 23 with very thin grit from.
Thin plates with thicknesses less than 4 mm are scattered only with two such spreading machines (wind scattering machines) according to the invention, since usually can not be safely removed with the conventional middle-layer spreading machines oversized or faulty grit.
Wind scattering machines oversized or faulty grit.
Middle layer spreaders are switched off to switch to thin plate production.
