Description

The method and apparatus that is used for the fiber web duse process
Technical field
The present invention relates to a kind ofly be used for the method for fiber web duse process and by claim 8 equipment that is used to implement described method as described in the preamble by claim 1 is as described in the preamble.
Background technology
In order to make fiber web, adopt so-called air lay method by fiber and fibre blend.Here relate to fibroreticulate duse process method, wherein fiber or the fibre blend with a large amount of separation is laid on the lay band to form a material layer by air flow.The lay band make ventilative and with an aspirator collaborative work, this aspirator produces and is used for admission of air and is used for the suction streams of fiber placement on the upside of lay band.For this reason, in the district that is shaped, send fiber continuously, make and in the district that is shaped, export formed material layer continuously by driving the lay band by a building mortion.Then make material layer reinforce or cause the fiber web of multilayer by further lay.For example by the known this equipment that is used for the method for fiber web duse process and is used to implement this method of WO2006/131122A1.
Even lay down fibre has the material layer of constant weight per unit area with formation problem has been proposed in this known method and equipment especially.The weight per unit area of particularly high and material layer hour in speed of production, inhomogeneities occurs in the lay structure of the material layer that is produced, wherein the weight per unit area of material layer mainly is shaped and is distinguished interior suction and fibre feeding and the influence that is subjected to the belt speed of lay band.For example, the suction that in the district that is shaped, is subjected to of lay band usually than outside the district that is being shaped by force.For example, cause the variation meeting of the uneven air flow of weight per unit area in the material layer that the lay structure is caused adverse effect.Equally, inhomogeneities that suction is flowed in the district that is shaped or turbulent flow also have adverse effect to the homogeneous texture of material layer.
In order to obtain weight per unit area as far as possible uniformly in lay down fibre with when forming material layer, in known method and equipment, measure and the monitoring aspirator in pressure drop so that can produce suction streams as far as possible uniformly.Here in the district that is shaped, one or more baffle plates are equipped on lay band downside, with the open cross-section of control aspirator.Though with this mass flow that can pro-active intervention lay be played a decisive role, shortcoming is, produces additional eddy current on the downside of lay band, this eddy current directly works to the mass flow that is created on the lay band equally.Therefore particularly when material layer is thin,, produce quality fluctuation once more in order to obtain having the fiber web of little weight per unit area.Another shortcoming of known method and equipment is the inertia/inertia of system, because just had the inhomogeneities of mass flow when pressure drop occurring in aspirator.
Summary of the invention
Therefore the objective of the invention is, provide such method and such equipment that is used to implement this method that is used for the fiber web duse process, even also unconjugated fiber placement can be become a uniform material layer in high speed of production during with little weight per unit area with equipment in this way.
According to the present invention, this purpose realizes by method with claim 1 feature and the equipment with claim 8 feature.
The good improvement project of the present invention is determined by the feature and the feature combination of corresponding dependent claims.
The present invention is different with the principle that fiber is laid in as far as possible equably in the district that is shaped of passing by.On the contrary, the invention enables fiber to be laid in the shaping district with can having quality fluctuation, thereby can in the district that is shaped, produce material layer with irregular weight per unit area.But in order on the lay band, to obtain having the homogeneous material layer of constant weight per unit area, according to the present invention, material layer on the guiding lay band upside passes an adjacent homogenization zone (Kompensationszone), the vibration by excitation/excitation material layer in this homogenization zone produce the fiber on the lay band upside homogenizing (ausgleichend) distribution.By the materials conveyance of the generation of the vibration in the material layer, make that the thick-layer position of material layer and thin layer position are balanced mutually to the equal voltinism of the little group of fubril/fiber.
Also be difficult for expecting the present invention by the method and apparatus known to the DE4318967A1.In known method and known device, form one and have the staple fiber nonwoven fabrics of directed artificial fibre.In order to make the staple fibre orientation, they are applied on the plate of a trough of belt, wherein encourage the mechanical oscillation of this plate by a vibrator, then with the staple fibre of orientation from this plate lay to a backing plate on to form fiber web, then carry out compacting.But this fiber directed earlier method and apparatus before lay can't be implemented in the air-laid process process.Here fiber must become fiber web by the air flow lay in the district that is shaped.Therefore this known method comes from equally and makes fiber obtain equal this theory of material layer of even orientation when lay.And the present invention comes from and makes fiber this principle of homogenising on laying device that lay is good.
Be not suitable for after fiber web is shaped, obtaining the homogenising of material layer equally by the method known to the DE10022110A1.In this known method, stand the sound field of a sound source by single fiber and granuloplastic fiber web, at this moment the above high-frequency range of the 20kHz of sound wave causes the soaking to the single fiber that is directed in oscillator field.But this high frequency of sound field is unsuitable for producing the material stream of fibrous mass in material layer.Fiber web is directed between screen cloth in this external known method, so the thickness of material layer has been determined by the spacing of screen cloth.Therefore from DE10022110A1, can not get method and apparatus of the present invention.
In order to implement method of the present invention, equipment of the present invention is done to such an extent that be with a homogenizer, and this homogenizer is nearby located to set to the lay band at next-door neighbour's building mortion.Therefore the material layer that produces by forming process can directly be directed into homogenizer on the lay band, utilize the vibration of this homogenizer by the excitation material layer produce the fiber on the lay band upside homogenizing distribution.
According to a kind of favourable improvement project of the present invention, vibrational excitation to material layer can directly produce on material layer or produce by the vibrational excitation to the lay band indirectly, and vibration here preferably produces on the vertical direction of the lay band that substantial horizontal is advanced.
The vibrational excitation of material layer in homogenization zone can directly produce by a vibrator according to the different of the frequency range of hope and amplitude range, and this method modification is especially for the indirect vibrational excitation of material layer.
Alternatively, also can encourage the vibration of material layer by pulse of air stream or air-borne sound.
In order to obtain the vibrational excitation targetedly on the entire machine width, preferably adopt such method modification, in this method modification, in homogenization zone, on machine-wide, encourage material layer so that the material layer vibration linearly.The distribution of the fiber in the material layer also can improve by such mode, and promptly shape ground produces vibration on material layer.
In the situation of face shape excitation, particularly the area district given in advance to material layer handles especially in homogenization zone.Therefore for example also can in material layer, produce predetermined Mass Distribution.With employed raw-material different,, also can carry out vibrational excitation according to parameters of technique process with different frequency and amplitude according to a kind of favourable improvement project of the present invention.Wherein in homogenization zone both on machine direction also at the transversely formation difference on the frequency and the difference of vibration of machine direction.
In order to guarantee the reliable connection of the fiber in the material layer, in homogenization zone,, vibration is arranged in homogenization zone but still maintain being adjacent to and carrying of material layer although make equally with aspirator suction lay band.
In order to produce mechanical oscillation, homogenizer has at least one and the joining vibrator of lay band.
In order to produce medium frequency and bigger amplitude, vibrator preferably includes the camshaft of one or more rotations, and wherein said camshaft has a plurality of cam ground that are arranged on the periphery and extends transverse to the lay band.Wherein for example the amplitude of described vibration can be determined by the cam height of camshaft substantially, the driving rotating speed of the quantity of the cam on the camshaft periphery and camshaft has been determined the frequency of vibrational excitation, comes the mechanical oscillation at homogenization zone underexcitation lay band like this.
But also have such possibility alternatively, promptly single or multiple vibrating elements are set as vibrator on lay band downside, described vibrating elements is bearing on the downside of lay band and causes the vibration of lay band.Can particularly produce mechanical oscillation thus with less amplitude and upper frequency.
Different according to the kind of fiber in the material layer and fibre blend and structure can be come excited vibration by the air sound source that is arranged on above or below the lay band.Such vibrational excitation particularly is used on superfine fibre or the powdery granule.
But, can come excited vibration by pulse of air stream for thicker structure.Homogenizer has at least one or a plurality of compressed-air atomizer for this reason, these nozzles be arranged on the lay band above or below and be connected with a pressure source.
The change of frequency and amplitude when advantageously detecting vibrational excitation by a controller, this controller and vibrator or sound source or compressed-air atomizer are connected.Therefore in controller, can set accordingly/adjust according to process and fiber type.
For guarantee material layer on the lay band conveying and obtain the reliable guiding of material layer, according to the another kind of favourable improvement project of present device, lay band downside is provided with the suction adapter/suction connector to homogenizer of setting of aspirator.Thereby can in be shaped district and homogenization zone, aspirate the lay band continuously.

The specific embodiment
In Fig. 1, schematically illustrate first embodiment of the present device of the inventive method that is used to implement to be used for the fiber web duse process with side view, this embodiment has a building mortion 1, an one lay band 5 and an aspirator 9, they are stacked up and down and form the district that is shaped jointly.
In this embodiment, building mortion 1 compiles the forming head 3 that container 2, is connected on the downside that compiles container 2 by one and constitutes, and wherein forming head 3 exports 4 with a screen cloth and is connected.Compiling container 2 is connected with a unillustrated here fiber production device by an input pipe 21.
Forming head 3 has a plurality of impellers 23, and they are rotated driving, so that fiber is evenly distributed in the screen cloth outlet 4 from compiling container 2.But should point out emphatically here, the structure of the building mortion 1 in the present embodiment is an illustrative, also can use optional structure such as revolving cylinder to distribute and distribute fiber in principle.
Be provided with lay band 5 nearby from screen cloth outlet 4 below building mortion 1, this lay band can be driven along the direction of arrow by band drive unit 6.Lay band 5 is made ventilative also preferably being made up of wire cloth.
Be provided with an aspirator 9 below lay band 5, this aspirator has one first suction and takes over 10.1, and this first suction is taken over and extended in whole shaping district on the downside of lay band 5.Here the main size by screen cloth outlet 4 in district that is shaped is determined.
Near next-door neighbour's building mortion 1, set a homogenizer 11 to lay band 5.Homogenizer 11 has a vibrator 12, and this vibrator is made a piston cylinder unit 13 in the present embodiment.This piston cylinder unit 13 acts on the downside of lay band 5 by a supporting plate 14, can make supporting plate 14 together with the 5 in the vertical direction reciprocating motions of lay band by starting piston cylinder unit 13.The vibrator 12 that is made of piston cylinder unit 13 is controlled by a controller 22 in the present embodiment, makes described vibrational excitation cause certain vibration of material layer 7.Like this, frequency and amplitude that can vibration given in advance.
In order to implement method of the present invention, building mortion 1 is by input pipe 21 a large amount of fibers of input or fibre blends, and this fibre blend can be formed by plurality of fibers or by fiber and additive granules.These fibers are pneumatically carried and are admitted to be compiled in the container 2.Fiber or fibre blend arrive the forming head 3 from compiling container 2, and fiber is evenly distributed in the screen cloth outlet 4 in forming head 3, and passes through the air flow lay to lay band 5.Air flow produces by aspirator 9, and this air flow is taken over 10.1 suction lay bands 5 from downside by suction.Fiber lay on the surface of lay band 5 becomes a material layer 7, and exports from the district that is shaped continuously by lay band 5.
For the inhomogeneities of the fiber of balanced material layer 7 inside appearance in the district that is being shaped during the lay, material layer 7 is guided through a homogenizer 11 on the upside of lay band 5.Homogenizer 11 forms a homogenization zone, the mechanical oscillation that in homogenization zone, on lay band 5, produce lay band 5 by vibrator 12, and these mechanical oscillation are passed to the material layer 7 that guides on described upside.Because the fiber of combination or the integrated structure of fibre blend not yet, the vibration of material layer 7 causes the materials stream in the material layer 7, thus the inhomogeneities that Mass Distribution in the balanced material layer 7 and quality are piled up.Therefore the frequency and the amplitude of the mechanical oscillation that are complementary of setting and material layer and fiber are so that interior thick-layer position and the thin layer position of balanced targetedly material layer 7.
At this moment formed material layer is a fiber web 15, and this fiber web not only at machine vertically but also have Mass Distribution as far as possible uniformly on transverse machine and then has uniform weight per unit area.Then fiber web 15 is transferred on the belt system to carry out subsequent treatment, particularly the fiber in the material layer is reinforced.
Equipment of the present invention and method are particularly suitable for producing the fiber web with little weight per unit area and high speed of production.Here, can avoid usually in the fiber web of having finished, causing the uneven Mass Distribution at flaw position fully.
In homogenizer 11, implement, can realize with different flexible programs and design the vibrational excitation of material layer 7.Some embodiment only are described in the accompanying drawing below.
For example Fig. 2 illustrates a kind of embodiment of homogenizer 11, and it for example can be used in the equipment by Fig. 1.Here Fig. 2 only illustrates a part of the homogenization zone that is passed together with the material layer 7 of guiding on lay band upside by lay band 5.Vibrator 12 is made of a plurality of vibrating elements 16 in the present embodiment, and these vibrating elements are bearing in respectively on the downside of lay band 5.Each vibrating elements is all done the vibration of a vertical direction, makes to be energized to vibrate around lay band 5 is at a plurality of supportings position.Vibrating elements 16 vertically also has transverse machine to be arranged on the lay band 5 in many places along machine respectively.The embodiment that is used in the homogenizer 11 shown in Fig. 2 particularly can produce the mechanical oscillation with upper frequency and less amplitude.
In Fig. 3 and 4, another embodiment that is used to encourage mechanical oscillation is shown with a plurality of views.In Fig. 3 with side view, in Fig. 4, homogenizer 11 is shown with vertical view.Short of specifically indicating with reference to certain accompanying drawing, so following explanation all is suitable for these two accompanying drawings.
In the homogenizer shown in Fig. 3 and 4 11, vibrator 12 is made of a plurality of camshafts 17, and these camshafts are parallel to each other, extend on the entire machine width transverse to lay band 5 ground abreast.On the periphery of camshaft 17, be formed with a plurality of cams 18 that certain distance is provided with that leave mutually, these cams rotate with camshaft 17 and with the following side contacts of lay band 5.For excited vibration, camshaft 17 preferably is driven on the contrary with the angle of rotation direction that staggers, thus the vibration of excitation lay band 5, and this vibration acts directly on the material layer 7.
Be suitable for producing vibrational excitation linear or face shape on machine-wide according to the difference of structure at the embodiment of the homogenizer shown in Fig. 2 to 4 11, linear excitation for example can realize by camshaft.Preferably be created in mechanical oscillation in 2000Hz to the 20000Hz frequency range, peak swing<1mm.
But also can carry out vibrational excitation in principle, at this moment the vibration of the material layer 7 on direct-drive lay band 5 upsides to material layer.This embodiment is illustrated among Fig. 5, and homogenizer 11 has a plurality of air sound sources 19 in this embodiment, and these air sound sources are arranged on lay band 5 tops, and produces the air-borne sound towards material layer 7.Therefore particularly when adopting fine fibre, can make material layer 7 homogenising.
But also there is the possibility that air sound source 19 is equipped on lay band 5 downsides alternatively, in Fig. 5, is shown in broken lines this form of implementation.
Vibrational excitation in homogenization zone also can advantageously produce by a plurality of air nozzles, and these air nozzles produce pulses of air stream.
When making the fiber web of duse process, the material layer on the lay band comprises a plurality of individual layers usually.Each individual layer produces on the lay band by a building mortion for this reason.In order to carry out the homogenizing to Fiber Distribution or distribution of particles of the present invention, two kinds of basic schemes can be arranged according to the different of technical process and product.For this reason, the another embodiment that is used to implement the present device of the inventive method shown in Figure 6 in embodiment as shown in Figure 6, on the basis of the embodiment of Fig. 1, returns lay band 5 and is equipped with one second building mortion 1.2.Building mortion 1.1 and 1.2 is provided with mutually abreast, and forms fiber individual layer or particle individual layer on the surface of lay band 5 respectively.Like this, on lay band 5 surfaces, produce the material layer 7 of a multilayer, then in the homogenization zone with these multilayer material layer 7 input homogenizers 11.In homogenization zone, make material layer 7 homogenising that constitute by two individual layers, make the inhomogeneities occur owing to integral dispensing, caused by the thickness position basically fully by equilibrium.
But set an independent homogenizer 11.1 and 11.2 also can for alternatively each building mortion 1.1 and 1.2.This embodiment is shown in broken lines, and like this, the material layer 7 that is produced on lay band 5 by building mortion 1.1 comes homogenizing by homogenizer 11.1, and the material layer that is produced by building mortion 1.2 comes homogenizing by homogenizer 11.2.Therefore in comprising a plurality of layers composite construction, on whole fiber web, produce weight per unit area highly uniformly.
