Definitions
- the invention relates to a device for the production of synthetic wood panels, with a floor conveyor bunker with a discharge device that extends over the entire spreading width and downstream discharge devices and a forming belt arranged underneath.
- DE-A-3 109 151 discloses a device of the type defined in the introduction. In the manufacture of synthetic wood panels, it is necessary for later use that their strength properties are constant over the cross section of the respective synthetic wood panel. Synthetic wood panels with non-uniform material properties lead to rejects or a reduction in the lifespan of workpieces made from these building materials during further processing.
- the invention has for its object to compensate for errors in the density distribution occurring during the discharge of bulk material over the bulk width.
- a further embodiment of the subject matter of the invention is protected in the characterizing part of claim 3. In this way, a leveling effect is achieved by the oscillating rotating rollers over a certain length of the bulk material curtain.
- the device according to the invention can be used in all types of manufacture in the course of the production of synthetic wood panels, such as chipboard or fiberboard; it is therefore independent of whether the production of synthetic wood panels takes place by means of spreading spreading or by means of blowers or with the help of a combination of these two possibilities of lowering.
- the present invention is also suitable in the same way for depositing synthetic wood nonwovens on a forming belt directly or on documents which are transported by a forming belt.
- a bulk material veil 10 discharged from a floor conveyor bunker via discharge rollers 16 generally has the cross section shown in FIG. 1. It can be seen that a synthetic wood panel to be produced therefrom has a non-uniform density across its cross section when it is pressed into a panel in a heating press.
- slot walls are produced by specifying a slot 9 and rollers 1, 2 which oscillate back and forth according to double arrows 13, 14 (see FIG. 2).
- a bulk curtain 10 see FIG. 2 which is uniform in its thickness is produced.
- rollers 1, 2 show a pair of rollers 1, 2, whose axes 3, 4 run parallel to each other.
- spindles 5, 6, which connect roller bearings 7, 7 'and 8, 8', the rollers 1, 2 can be adjusted in parallel according to the circumstances, so that a corresponding slot 9 is formed in which a uniform bulk curtain 10 is formed.
- the surfaces of the rollers 1, 2 can also be roughened.
- the rollers 1, 2 can also be provided according to the invention with a plastic coating which has a high coefficient of friction in the axial direction, so that the bulk material veil 10 in the slot 9 is intensified evenly if it is a bulk material veil which contains a large part of fine bulk material is.
- the method according to the invention can be adapted to practically all bulk material veils 10, even if the material for the bulk material veil is designed differently, such as fine material, mixed material, coarse material, rectangular chips (strands), square chips (wafers) ) with practically constant density.
- the equalization of the bulk material veil in the transverse direction can be improved still essential if a plurality of such rollers 1, 2 (see FIG. FIG. 3) are arranged one behind the other i tzumblen in falling direction of the bulk material with different veil Schl.
- glued bulk material 17 is discharged from a floor belt bunker with a floor belt 15 and discharge rollers 16 for the production of synthetic wood panels.
- a discharge scraper belt can also take the place of the discharge rollers 16.
- the glued bulk material 17 is discharged and fed to the smooth rollers 1, 2, which were explained in more detail in FIG.
- a plane 18 conceived by the axes 3, 4, in which the axes 3, 4 extend, is oriented essentially orthogonally to the direction of fall of the bulk material curtain 10.
- the bulk material veil 10 is then fed to the forming belt 22 via a distribution device, either a throwing device 20 or a blower device 21.
- a distribution device either a throwing device 20 or a blower device 21.
- associations of these low-cost facilities are also possible.
- a synthetic wood fleece 24 is deposited on a forming belt 22, which carries documents 23 and moves in the direction of the arrow.
