Description
The present invention relates to a kind of aforementioned part according to claim 1, be used for producing the method for distribution material cushion that constitutes by at least one spread layer in forcing press, to suppress in the process of producing the timber plate, a kind of aforementioned part according to claim 16, be used for producing the distribution material cushion that constitutes by at least one spread layer with the equipment in forcing press, suppressed in the process of producing the timber plate and a kind of according to distribution material cushion claim 23, that in the process of producing the timber plate, be used in forcing press deburring and/or be used for preferably suppressing subsequently.
When producing the plate of material that constitutes by spreadable material; Scatter the distribution material cushion that becomes to be positioned on formed strip or the conveyer belt by particle or fibrous matter with the mixture that adhesive constitutes; Wherein, scattering material cushion is fed to the preliminary treatment machine that needs in case of necessity subsequently and finally is fed to press machine.At this; Usually adopt discontinuous laminating machine and the forcing press that moves continuously; Wherein, in the forcing press of continuously operation, be compressed on pressure and introduce under the situation of heat the pressed material pad that between two rotating steel bands compacting has the distribution of the dispersed particulates that is coated with glue.Except pure particle board (MDF), also adopt mach wood chip, these wood chips directionally scatter usually, to provide intensity along length and width timber plate that strengthen, that produce.At this, longitudinally the production type with the transversal orientation (OSB) and the distribution plate of longitudinally directed (OSL) only is different.Usually, on continuous double belt press or circulating pressure machine, produce this OSB and OSL plate.
In present plate of material production method, make the distribution material cushion of following type, these scatter material cushion and suppress subsequently:
-weight per unit area is along length and the uniform distribution material cushion of width
The distribution material cushion that-weight per unit area increases at longitudinal edge is scattered material cushion and is protruded compensation through in the process of compacting, making in the process of transporting, to make in the fringe region material unaccounted-for (MUF) or density loss.
-weight per unit area is along the length distribution material cushion different with width; Wherein, Usually scattering the head back and processing after the uniform homogeneous of weight per unit area scatters material cushion, in independent follow up device along producer to spreading continuously and/or isolated material bar additional materials or take out from scattering material cushion on width by withdrawing device.
Weight per unit area cloth type has some shortcomings along the present applicable cases of the discrepant distribution material cushion of length and width and the Economic Application aspect that is implemented in of machinery or equipment and technology aspect thereof:
Particularly in the device of the weight per unit area of intervening the best distribution material cushion of scattering, scatter material or produce the production interruption that the shut-down by expensive machines causes owing to milling is carried out in the zone by so-called " finishing machine " owing to spread other material bar.Particularly, be fed to the operation of scattering material when scattering on the material cushion equably at material bar and have problems, for these problems must be found out solution expensive, the machine technology aspect several centimetres or several decimeters wide.Also having of difficulty; Particularly under the situation of the smooth distribution material that is used to produce directed distribution plate (OSB-directional fiber plate), move apart the distribution material from the cover layer that scatters material cushion, this is because tend to stay coarse space at large-area wood chip when scattering material cushion and take out or wood chip.
In case the longitudinal edge that scatters material cushion is only carried out an edge to raise; Then usually along producer to or scattering in the head along the lengthwise of formed strip calibrating element movable sideways be set, these calibrating elements are used for moving more and more below scattering roller, along the longitudinal centre line direction of scattering material cushion the material of the uniformly dispersing in the fringe region.Also produce along the observed uniform weight per unit area of width that scatters material cushion, this weight per unit area has continuous elevated portion in the vertical side edge that is positioned at the outside.
This solution is favourable when compacting in principle; This is because the requisite measure that provides the edge that is used to scatter material cushion to draw high, and also in forcing press, in the fringe region, can obtain on increasing slightly of density or the whole area in plate of material density uniformly during protrusion scattering material cushion thus.
Be used to make the moulding circuit that scatters material cushion " moulding " can have the length that is as long as fifty meters, this moulding circuit is provided with the ring-type formed strip of scattering head corresponding to the top usually.Even at present good transporting is feasible fully, but the longitudinal edge of distribution material cushion still will bear vibration or as other preliminary treatment in steam impringement equipment, hot air device, preformer or analog.Worse, in a plurality of minimum deflections that can manifest edge distribution quality or position in the head of scattering in succession, these deviations cause the longitudinal edge degradation of scattering material cushion equally.
Can confirm in short, scatter material cushion and before can sending in the forcing press, must carry out deburring at longitudinal edge usually from the moulding circuit.Should avoid when particularly in the double belt press of continuously operation, producing continuously: the edge block of scattering material cushion when sending into the steel band place of forcing press peel off uncontrollably and fall into send in the slit or the following steel band at forcing press on cement.
Correspondingly, be provided for usually scattering the device of material cushion edge trim, these devices are pruned at the longitudinal edge place in the moulding circuit and are scattered material cushion.This has the advantage of economic aspect, that is, the distribution material that appears at this can be sent back in the distribution process again immediately, and material needn't be once more through expensive preparatory production process (preparation, dry, gluing).Yet this measure is also limited, this be because gluing long period of distribution material of sending back to and adhesive under the situation of not presenting pressure and heat along with the time hardens.Target must be that the distribution quantity of material that keeps sending back to is as far as possible little.But be apparent that, must carry out deburring to the fringe region that have the distribution material cushion of maximum unit area weight through continuous distribution rising according to above-mentioned embodiment.
In addition, experience and practice show, particularly for the material stream of relative free-falling, uncontrollable air-swirl after proportioning device, occurs, and these air-swirls cause the weight per unit area of the not expecting distribution along width and length.Thus, when thin plate is produced, present not good the fading in surface (growing dim) and perhaps even owing to scattering the density that corresponding notch stress concentration effect causes in material cushion or the plate of material move.
Present solution provides so-called pectination whereabouts slideway in the prior art to this, and these slideways are divided into a plurality of part/zones along width with material stream.The trouble but these devices operate, easy blocking also is difficult to cleaning.
Task of the present invention is to provide a kind of method, equipment and distribution material cushion that is used to produce the one deck at least that scatters material cushion; Wherein, with good and simple methods scalable along the weight per unit area of the variable-width that scatters material cushion and/or can with respect to the air-swirl that occurs improve through proportioning device quantitatively after or after the guider along the weight per unit area distribution of width.Particularly can scatter the little weight per unit area of average weight per unit area of material cushion at the longitudinal edge place adjusting ratio that scatters material cushion, less with maintenance through the quantity of material of the deburring of distribution material cushion.
The present invention to method solves this task through following mode: by at least one mechanical guiding device between proportioning device and the dissemination apparatus, the distribution material in material stream substantial lateral is at least in part stablized when the direction of motion is moved at it in the distribution material of producer in mobile and/or material stream of formed strip at least in part.
Solution to equipment is; For make in the material stream the distribution material at least in part substantial lateral in the producer of formed strip to moving and/or, at least one mechanical guiding device being set between proportioning device and dissemination apparatus for the distribution material in the material stream is stablized along the direction of motion at least in part.
Particularly according to the method production of claim 1 and/or in equipment according to claim 16; Scattering material cushion is characterised in that; At two longitudinal edge places that scatter material cushion, be provided with than quantitative weight per unit area DFG and/or than along the average weight per unit area of distribution material cushion width little the weight per unit area of Duoing.Main regulation, weight per unit area are preferably from the deburring plane of longitudinal edge towards regulation and constantly increase.
Can in scattering head, will scatter the layer of material cushion at present or be adjusted to and make the weight per unit area distribution even by religious doctrine according to the present invention and solution along width by scattering a individual layer distribution material cushion that head processes.This is specially adapted to orientable and smooth distribution material, and is particularly all the more so when producing directed distribution plate (OSB).Make it possible to produce the weight per unit area distribution especially for the lightweight construction board of furnature construction but also can produce, these lightweight construction boards mainly have the regional little weight per unit area that is provided with than in order to arrange holding element (shelf, drawer, door accessory, back wall bracket).Also can for example be provided with respective edges for the edge sealing in the respective texture/color of smooth side, these edges are provided with bigger weight per unit area equally.This structure particularly can be imagined as edge-protected or be used for better introducing the edge groove that is used for the edge sealing bar through processing.Can stipulate that in addition said weight per unit area is meant quantitative weight per unit area or the average distribution weight per unit area that scatters weight per unit area and/or not influenced by guider that scatters the head top.
In addition, can the distribution material cushion be scattered the outer longitudinal edge that becomes to make in dispersion zone or the distribution head region has particularly than the little weight per unit area of average weight per unit area that scatters material cushion.This preferably so realizes: in the material stream that falls, scatter part in the material edge region (bring see transverse to moulding) in scattering head through during move along the central longitudinal length direction of distribution material cushion or moulding circuit.Observe along the center position that scatters material cushion from vertical side, at first produce and scatter less weight per unit area in the material cushion, it separates and finally transfers to the average weight per unit area that scatters material cushion with bigger weight per unit area.If the now preferable peak (peak value) through regulating at big weight per unit area is being located this distributions material cushion deburring, then obtain as far as possible little deburring material in an advantageous manner but be the distribution material cushion that has the weight per unit area increase of expectation in the edge region.
In the present invention, relate to following regulation about used notion:
Possible guider does not preferably influence the material stream of whole whereabouts or introduces the material stream that scatters head, but only influences its part.This is necessary, to avoid scattering the distribution space that enlarges in the material cushion.Equally, as often the insight, not calibrating the distribution width that scatters material cushion, but preferably move or the only part of diverting material stream, to realize along the different weight per unit areas that scatter the material cushion width through guider in width adjusting.This can implement by one or more guiders.Notion " quantitatively weight per unit area " is described the theoretical unit area weight of material stream, controllably discharges when scattering material and scattering on the formed strip that also is placed on width B in the head there so that it is transferred to along width B 1 when proportioning device, this notion occurs.Preferably, B>B1, but this is not compulsory.Material stream has the degree of depth of length L along the producer of formed strip to the/direction of motion.Scatter weight per unit area and describe weight per unit area width, that scatter material cushion along formed strip with width B 2.If through scattering head or other device quantitative weight per unit area is not changed, then quantitatively weight per unit area equals to scatter weight per unit area.If, then scatter material cushion and obtain new width B 3, wherein be suitable for: B3 < B2. because of deburring to scattering the material cushion deburring
Be used for to scatter pointedly the device that material is taped against on the formed strip and be called as a dissemination apparatus that scatters in the head.This device preferably is located in formed strip top, and as the mechanical organ of last machinery, particularly motion scatter material leave scatter head and be positioned on the formed strip or scatter on the material cushion before with scatter material and contact.
Particularly stipulate now; Pass through guider; The basic uniformly quantitative weight per unit area DFG of material stream is varied to discrepant distribution weight per unit area SFG; Wherein, discrepant distribution weight per unit area SFG should be understood to the profile that can have different shape, as following also will further describe the ground.At this, implement the stable and/or mobile of the interior distribution material of material stream with some stages by guider in succession.Because its motion and generation can cause scattering material along the vertical or horizontal mobile air-swirl of formed strip the time, stable is necessary when smooth or orientable distribution material particularly.
Preferably, material flow into scatter head and/or material stream with implement before the mechanical organ of the motion of scattering head contacts first stable and/or mobile.Scatter material and should preferably spread to formation distribution material cushion on the formed strip with width B 2, this distribution material cushion corresponds essentially to the width B 1 of the material stream after the proportioning device.
Equally preferably; By guider, in adjacent at least one other zone that has the first area of the weight per unit area FH bigger and have particularly little weight per unit area FG along adjusting in the plane weight SFG of distribution unit of width B 2 than quantitative weight per unit area DFG than quantitative weight per unit area DFG.Particularly so stipulate during the lightweight construction board in producing furnature construction.To this; Can scatter in the weight per unit area SFG along (discrepant) of width B 2, will have the several regions of big weight per unit area FH and between these zones, the less zone of weight per unit area FG is arranged so that in the subsequent process of zone forcing press after with big weight per unit area FH can be as dividing through the separating plane of the plate of material of suppressing and/or being used as the zone of the accessory in fixing device for installing or the furnature construction.
In alternative or additional embodiment, can regulate at the longitudinal edge place that scatters material cushion than quantitative weight per unit area DFG little the weight per unit area of Duo, the distribution quantity of material that appears at the edge-neatening apparatus place with maintenance is less.
Preferably; The distribution material cushion of scattering between head and the forcing press is trimmed to the width B 3 with longitudinal edge by edge-neatening apparatus at the longitudinal edge place; Wherein, longitudinal edge can be arranged in the zone with weight per unit area FH bigger than quantitative weight per unit area DFG.Preferably, as mechanical guiding device, at least one is arranged between proportioning device and the dissemination apparatus, preferably can remains at least in part along in the distribution material of direction of motion whereabouts by at least one adjusting device motion and/or the guide plate that rotates.Additionally or alternatively; For fear of incalculable cross-current; At feed bin and scatter between the head basically towards the whereabouts direction, scatter material along the guide vane guiding, wherein, it is angled that guide vane is arranged to respect to scatter material or material stream equally adjustablely at least in part.Under special situation, meaningfully, has the axial symmetry of being preferably about the geometric center of width B 2 along curve shown in the distribution weight per unit area SFG of width B 2.
Under the situation of the distribution head that costliness designs, meaningfully, scatter material and be arranged on the dispersal device between guide vane and the dissemination apparatus to delivering at least one by guide vane.
In order to improve and/or adjustment process parameter automatically; Particularly under different production charging situation meaningfully; Width along formed strip is provided with guide vane and/or at least one guide plate; And, regulate guide vane and/or guide plate with respect to the distribution material that moves along falling direction and/or with respect to formed strip and/or with respect to the position of the sidewall that scatters head by adjusting device for stable and/or influence quantitative weight per unit area DFG.Especially preferably, guide plate along the producer of formed strip to orientation on this guide plate is introduced material stream 24 length L basically 10% to 80%, be preferably between 30% to 50%.This is with the obstruction in the meaningful and actual methods prevention fall area and scatter the so-called dispense orifice in the material cushion.
Equipment just itself is independently, and can be suitable for said characteristic independently.Simultaneously, this equipment also is particularly suitable for implementing the method according to claim 1.

Figure 10 illustrates the part of the possible structure that has guide plate of guider with two sketch mapes of correspondence, and the adjusting device under this guide plate has to be regulating the different angles of guide plate, and
That Figure 11 illustrates is possible, by movable two adjusting devices that push rod is connected with each other guide plate.
The left side illustrates with sketch map and is used to produce the example apparatus of scattering material cushion 7 in Fig. 1, and this distribution material cushion is used in forcing press 22, suppressing.See side view according to the hatching line of left figure on the right side.In this equipment, scatter that material 9 is fed in the feed bin 2 and controllably be fed to proportioning device 15 by smoothing out with the fingers the annular rotating feed bin tail band 16 of scraping part (R ü ckstreifrechen) 25 and being positioned at its below.Proportioning device 15 draws off the distribution material along width B 1 with uniformly quantitative weight per unit area DFG (lower right illustrates).Along usually corresponding to the direction of motion 12 of the falling direction that scatters material 9, constitute thus basically move along a direction of scattering 1, have transverse to producer to the width B 1 of 11 (corresponding to the directions of motion of formed strip 8) and along this producer to the material stream 24 of length L.At this; Material stream 24 at least one mechanical guiding device 5 of process are so that the distribution material 9 of motion in material stream 24 is stablized and/or regulated along the width B 2 of formed strip 8 or distribution material cushion 7, with respect to the discrepant or uneven distribution weight per unit area of the quantitative weight per unit area DFG SFG that exists along width B 1.Especially preferably; Basically proportioning device 15 back and material stream 24 get into scattered before 1 and/or material stream 24 with scatter movable machinery element (for example, disperseing roller, a sieve or analog) contact first of 1 before be provided for the guider 5 of the distribution material 9 in stable and/or the mobile material stream 24.Scattering 1 place or interior delivery location in order to regulate material stream 24, guide vane 18 can be provided with optional machinery or self-checking device (not shown).At this, guide vane 18 is in formed strip 8 and/or scatter on the width B 1 of scattering material 9 on 1 the whole width, at least and be arranged on proportioning device 15 back.Shown in the right figure among Fig. 1; Two guide plates 10 are being arranged at " on the optional guide plate 18 " on the width; These two guide plates 10 play at material through their angled layouts and the length L (left figure) that only partly interferes with material stream 24 and flow down the effect that mobile material in the process that falls to passing through or flow through flows the part of 24 distribution material 9; Thereby, produce the inhomogeneous profile that scatters the distribution weight per unit area SFG in the material cushion 7 from uniformly quantitative weight per unit area DFG (bottom-right graph) in formed strip 8.Guider 5 through machinery only partly stretches into material stream 24, still keeps existing enough distribution materials 9 that is not moved, being used to cover formed strip 8, thereby, can in scattering material cushion 7, not produce and scatter deficiency or " plaque point ".
Can be provided with the one or more dispersal devices 4 that are used to scatter material 9 scattering in 1, these dispersal devices are preferably disposed between guide vane 18 and the dissemination apparatus 14.
By being embodied as another guider 6 the same, between dispersal device 4 and dissemination apparatus 14, can further strengthen being used for effect along the longitudinal edge 17 lateral adjustment weight per unit areas that scatter material cushion 7 with guider 5.At this; Guider 6 does not should be understood to the lateral adjustment device that is used for width B 2 yet; But only playing the effect of moving the another part that scatters material 9, this is because " the theoretical degree of depth " L extends on long zone now, and guider 6 only occupies a part wherein.This for produce at longitudinal edge 17 places that scatter material cushion 7 scatter weight per unit area SFG strong descend meaningful especially so that be lower than along the average distribution weight per unit area of the distribution material cushion 7 of width B 2 and/or along the quantitative weight per unit area of the proportioning device 15 of width B 1.
Distribute at the various weight per unit areas along width B 1, B2 and B3 shown in Fig. 2.This distributes at the weight per unit area that this relates to the longitudinal edge 20 that scatters material cushion 7 and 17 places specially.Nethermost figure is the common distribution material cushion according to prior art, and this distribution material cushion quantitatively and by being displaced sideways wall complete (about material stream) is reduced to width B 2 from the whereabouts width 21 that scatters material cushion on width B 1.At longitudinal edge 17 places, (steeper) that in the initial distribution material cushion of scattering 7, produce the weight per unit area of edge side risen.Subsequently, when the distribution material cushion reduces to width B 3,, remove the distribution material 9 of higher proportion again through separated region with this elevated portion owing to deburring.Above two illustrate edge and scatter with curved edge characteristic, thereby, preferably produce the maximum that edge side scatters weight per unit area SFG through edge-neatening apparatus 23 separating section at new longitudinal edge 20 places.In the superincumbent diagram; (material stream 24) whereabouts width 21 is corresponding to the width B 2 of scattering material cushion; In the figure of centre; Reach and be used for higher lug boss deburring, the fringe region place, this be because guide plate 10 for example deeper stretches in the material stream and/or the decline width 21 of material stream via be displaced sideways the wall (not shown) be reduced to the width B 1 of scattering material cushion 7 and therefore the edge region place scatter more materials.In order to compare better, do not influencing and be taped against 8 last times of formed strip under the situation that its weight per unit area distributes when scattering material 9, be drawn into quantitative weight per unit area according to B1.
Fig. 3 illustrates the vertical view cutaway drawing that cutd open according to the guider 5 of Fig. 1; This guider has the guide plate 10 that is parallel to falling direction at guide vane 18 places, with change over to from feed bin 2 scatter that stable material was 9 that constitute by scattering 1 o'clock, the material stream 24 of length L and width B 1.This has following background: the distribution material settling out that causes to fall and break is useful fully.In addition, between the guide plate 10 that only partly stretches into material stream 24, can not constitute as by the known obstruction risk of prior art with variable or a plurality of closure whereabouts slideway/passages that are provided with along width.
As long as exist to regulate scatter the various solutions of width, the structure that a plurality of guide plates are set with the mode of holding fix can be favourable.For example be reduced to 2.5 meters or 2 meters from 3 meters if scatter width now, so said guide plate 10 can not inwardly move so that implement this method far enough.For this reason, it is favourable along width a plurality of guide plates being set, and to regulate width as far as possible changeably in addition, can realize the common whole length adjusted width at the distribution head fully, that is, and and the side direction guide plate.In the case, in an advantageous manner by a plurality of guide plates, more materials along the width third side of formed strip to moving, thereby, constitute the cloth type of expectation.
Fig. 4 illustrate scatter 1 with forcing press 22 between the regional vertical view of moulding circuit; It illustrates different widths, as the width B of formed strip 8, quantitatively weight per unit area DFG or material stream 24 width B 1, scatter material cushion 7 or scatter the width B 2 of weight per unit area SFG and edge-neatening apparatus 23 after, be ready for suppress and through the distribution material cushion 7 of deburring along producer to 11 width B 3.
Fig. 5 to 8 illustrates the relevant diagram of the possible production process of scattering material cushion 7 with exemplary parameter.To illustrate in proper order with the opposite accompanying drawing of producing of material stream; Because Fig. 5 illustrate have longitudinal edge 20 and width B 3, be suitable for suppressing and the distribution material cushion 7 of deburring; Fig. 6 illustrates the distribution material cushion of not deburring, and Fig. 7 and 8 illustrates the distribution material by guider 5 mobile whereabouts.Scatter material cushion 7 and have along the inhomogeneous profile of the distribution weight per unit area SFG of width B 3 with respect to uniformly quantitative weight per unit area, wherein, the position of big weight per unit area FH and the zone of less weight per unit area FG are alternately.The number that is used for the guide plate of bigger and/or less weight per unit area FG can also be more than one, shown in particularly Fig. 7 and 8.The weight per unit area of the distribution weight per unit area SFG of expectation increases at the longitudinal edge place for compacting.
Fig. 6 is illustrated in and scatters the original width that has longitudinal edge 17 afterwards and in the distribution process is the distribution material cushion of B2.Corresponding ground, Fig. 7 illustrates the necessary for this reason adjusting to guider 5, with the quantitative weight per unit area DFG of influence along width B 1, to produce the distribution weight per unit area SFG along width B 2.To this, guide plate 10 tilts with respect to the direction of motion 12 of the material stream 24 that is made up of distribution material 9.
Fig. 8 illustrates in the material stream 24 that guide plate 10 only partly stretches into the degree of depth or length L at last, and is used for along the width B 1 distribution material 9 of mobile material stream 24 partly.
Fig. 9 illustrates the multistage layout of the guider of using or being provided with for accurate adjustment for complicated method, and it constitutes by guider 5 with along the guider 5' that the direction of motion 12 of material stream is positioned at downstream.First guider 5 is used for moving distribution material 9 along width B 1, wherein, and in order to stablize and to make the material that moves along the direction of motion 12 flow 24 homogenising and the second guider 5' is set subsequently.Therefore, " wider " that prevent to scatter material 9 through guider 5' moves/displacement, and guider 5' causes scattering the accurate adjustment of moving of material 9.Figure 10 illustrates the part of the be furnished with guide plate 10 of guider 5 with the sketch map of two correspondences, and the adjusting device 19 under this guide plate has is to regulate the different angles of guide plate 10.Guide plate 10 can be by variations of turning up the soil at interval of adjusting device 19 and guide vane 18, and 27 moves through boring a hole, and changes accordingly and stretch into material and flow 24 the degree of depth that stretches into.In order to regulate the angle of guide plate 10 with respect to material stream 24, guide plate 10 has groove 26, and when prerotation vane 10 rotated moving axis 28 rotations by adjusting device 19, guide vane 18 penetrated these grooves.
