Description

The invention relates to a laying device and a laying method with the features in the preamble of the independent claims.

From practice, nonwovens for forming a multi-ply web on a take-off belt are known, wherein the nonwoven depositor deposits the continuously fed card web in overlapping layers on the discharge belt. Such a liner is designed as a cross-lapper, wherein the discharge belt moves during the pile storage, with the result that the deposited pile layers show crossing oblique orientations with a zig-zag layer formation. In the fed batt, the fibers may have a predominant orientation, e.g. have a predominant direction component in the longitudinal direction and running direction of the fed card web. In the fleece, these fiber orientations intersect, wherein the crossing angle is an obtuse angle of more than 90 ° because of the close ply closure.

From the US 5,476,703 A It is known to change this crossing angle of the fiber orientations and also of the longitudinal extent of the deposited pile layers by a stretching device connected downstream of the nonwoven layer, which stretches the web and thereby reduces the crossing angle.

From the US 5,454,145 A It is also known to supply the stretched nonwoven another Kreuzleger and by shingled zigzag storage on the discharge conveyor a new further fleece with multiple crossed To form fiber orientation.

The US 5,111,552 A and the US Pat. No. 2,889,583 each teach a laying device with a discharge device, which is aligned transversely to the laying direction of the laying device.

The AT 310 045 B discloses a laying device in which the discharge direction and the laying direction are aligned.

The WO 97/32069 A describes a nonwoven layerer in the form of a cross-lapper, which deposits the pile layers with alternating orientation and fiber orientation on the discharge device.

The post-published WO 2001/064103 A1 shows a laying device with a discharge device which is aligned obliquely to the laying direction of the horizontal tray.

The EP 2 003 232 A1 deals with the storage of rope-like fiber strands.

It is an object of the present invention to provide an improved laying technique.

The invention solves this problem with the features in the independent claims.
The claimed laying technique has the advantage that nonwovens can be formed with a more uniform fiber orientation. Such nonwovens may have fiber orientation dependent special strength properties. For this purpose, it is favorable if the deposited material layers or pile layers in the nonwoven have the same positional orientation and the same predominant fiber orientations. The orientation of the predominant fiber orientation can be adjusted and adjusted as needed, with the alignment angle between the laying and feeding direction and the discharge direction is adjusted accordingly.

For this form of material storage, in particular pile storage, and the web formation, it is advantageous if the stored material or pile layers are separated from each other. This separation can take place before depositing on the discharge device, preferably in the region of the laying device. A coherent material or card web can be supplied on the input side and, if necessary, stored before or within the laying device. For a constant alignment of the stored material or pile layers, it is advantageous if the discharge device is during this storage process. The storage can then be a defined one-dimensional transfer movement. Here, a lifting device can shorten the distance.

The claimed laying technique has the advantage of a particularly gentle treatment of highly sensitive material and pile layers. Disturbances of these layers during transport and storage or transfer process and corresponding adverse effects on the nature and orientation of the stored material and pile layers can be avoided.

Particular advantages are offered by a laying technique with a nonwoven layer and a downstream intermediate carrier, wherein the nonwoven layer can provide intermediate storage of the supplied material. The intermediate carrier may have a receiving and an opposite delivery side, wherein the separation of a possibly continuously supplied material or card web can be done in individual piece material or pile layers in the region of the intermediate carrier, which is particularly favorable for the exact positioning and storage of the individual Material or pile layers is. The intermediate carrier allows, at the feed or receiving side, a continuous material web or card web, which is already separated into individual pieces to record with a rolling motion, to position accurately on the discharge side and to pass in a one-dimensional storage movement at the discharge device target and interference. The deposition material or the batt can thereby be kept in a controlled manner in the intermediate carrier, for which a suction device is favorable. The delivered material or pile layers and the one-ply or multi-ply nonwoven formed thereby can also be held in a suitable manner on the discharge device, in particular by suction.

The claimed laying technique has the advantage of a high laying precision in conjunction with a large freedom from interference. The construction and tax expense is comparatively low. It is also beneficial to be able to handle different deposit materials, in particular batt, and to lay a nonwoven. By a variable orientation of the discharge device, the desired fiber orientation can be adjusted.

Furthermore, a plurality of laying devices can be arranged one behind the other at a common discharge device, which may possibly also have different alignment angles. As a result, any desired crosswise fiber orientations can be set particularly precisely. In addition, other deposition materials, e.g. a reinforcing agent in the form of fabrics, meshes or the like or other structural layers for the nonwoven structure are introduced deliberately and with little effort.

The claimed laying technique is to a very high degree the precision requirements of modern high-performance materials, in particular carbon fibers or the like and formed therefrom technical nonwovens defined properties. In particular, thanks to their precisely defined properties, in particular their strength behavior, such nonwovens can have a smaller thickness than previously used nonwovens with more or less disordered fiber orientations, whereby the associated weight is also reduced. This expands and improves the possible uses of such nonwovens, for example in the automotive and aircraft industries. Such nonwovens are also particularly suitable for composite materials, wherein, for example, the nonwoven before or during the process with a synthetic resin or other suitable material connected, in particular soaked, is.

The claimed laying device can be used as a single unit or as part of a fiber plant and in combination with an upstream pile producer and a downstream solidifying device for the nonwoven.

In the subclaims further advantageous embodiments of the invention are given.

The invention relates to a laying device (2) for a deposition material (5) and a fiber plant (1) with such a laying device (2). The invention further relates to a method for depositing deposition materials (5), in particular Faserfloren, and for adjusting fiber orientations in a nonwoven (8).

In FIG. 1 schematically a fiber plant (1) with a laying device (2), a plurality of material generators (3), in particular pile producers, and a solidification device (4) is shown. The laying device (2) can have one or more laying devices (16, 17) and one or more discharge devices (18). In the embodiment shown, two laying devices (16, 17) are the same or different Depositing materials (5,37) connected to a common discharge device (18). Furthermore, each laying device (16, 17) is assigned a feed device (14), with which the depositing material (5, 37) coming from the material or pile generator (3) is fed in the running direction (7). The discharge device (18) has a preferably straight extension and a discharge direction (13) aligned along its course.

The feeding of the deposition material (5,37) is preferably carried out continuously and in a running or closed or continuous material web. Alternatively, a discontinuous and e.g. Piece by piece possible.

The laying device (16, 17) serves to deposit the supplied depositing material (5, 37) on the removal device (18) and thereby to form a fleece (8). For this purpose, the laying device (16, 17) places a plurality of material layers, in particular pile layers (9), in the discharge direction (13) one behind the other on the removal device (18). The fleece (8) may be multi-ply, wherein several of these material or pile layers with overlap and longitudinal offset are arranged one above the other. This creates a scale-like storage with layer closure. Alternatively, the layers of material (9) can be arranged individually and one behind the other and optionally at an axial distance to form a single-layer nonwoven fabric (8).

The laying device (16, 17) has a laying direction (7), in which it deposits the material or pile layer (9) on the removal device (18). The laying direction preferably coincides with the feed direction (7). There may be a selectable alignment angle (α, β) between the laying direction (7) and the discharge direction (13) and between the laying device (16, 17) and the removal device (18). As FIG. 6 clarified, the devices (16,17,18) can possibly be rotated about an axis relative to each other. In the shown Embodiments deviates from the alignment angle (α, β) of 90 °, so that the deposited material or pile layers are aligned obliquely to the discharge device (8).

The material or pile layers (9) can be separated from each other and separated before storage. For this purpose, a separating device (19) may be present at a suitable location and with suitable training. The deposition material (5, 37) supplied on the input side can form a coherent web, in particular a card web, from which said material or web layers (9) are separated to form individual pieces. This separation can take place before the laying device (16, 17) or within the laying device (16, 17).

The deposition material (5,37) may have the same or different training. In the exemplary embodiment shown, the deposition material (5) coming from a first pile producer (3), in particular a carding machine, is a batt which has a cotton-like shape and consists of short cut fibers, so-called staple fibers. The fiber materials are arbitrary. It can be e.g. to technical fibers, especially carbon fibers, fibers made of plastics or natural fibers of cotton or the like., Act. The batt (5) may also contain other additional materials, e.g. Metal threads or the like., Include.

As FIG. 1 and 6 clarify, in the deposition material (5), in particular in the batt, a predominant fiber orientation (6) are present. In this case, for example, the majority of the fibers have a substantially identical alignment component, which is aligned, for example, along the feed direction (7) or in the longitudinal direction of the card web. Not all fibers have the same orientation and are parallel. You can take slopes and hook each other. It can also give some transverse fibers.

An in FIG. 1 indicated other deposition material (37) may be, for example, a fabric or a grid, which may also have a predominant structural direction or orientation. Such a fabric (37) or grid may consist of textile fiber materials, metal, plastic or other materials. For this purpose, the deposition material (37) can, for example, reinforce a nonwoven fabric (8) consisting mainly of fibers or can otherwise impart desired physical properties to it. The material generator (3) can be designed accordingly. The term of a material or pile producer includes in addition to production facilities for the said storage material (5,37) and dining facilities, with which, for example, an otherwise produced storage material prepared and fed.

In modification of the shown FIG. 1 For example, the second or each additional deposited material (37) may also be the same or different fibrous web which may have the same or different predominant fiber orientation (6).

As FIG. 1 and 6 illustrate, the laying device (16,17) sets the material or pile layers (9) with the same orientation and fiber orientation (6) on the discharge device (18). Thus, within the web (8) deposited here, the material or pile layers (9) have the same orientation throughout. Furthermore, the deposited web (8) and its material or pile layers (9) may have the same predominant fiber orientation (6). There may be a selectable angle between the longitudinal extension of the fleece (8) and the fiber orientation (6) which can be adjusted by the aforementioned alignment angle (α, β).

If a plurality of laying devices (16, 17) place material and pile layers (9) on the removal device (18) in succession, their layer orientation and fiber orientation (6) can be the same. FIG. 1 shows a variant in which the first laying device (16) has an alignment angle (α) and the second laying device (17) has a different alignment angle (β). As a result, intersecting layer orientations and fiber orientations (6) with selectable angular relationship can be set.

The discharge device (18) can be designed constructively in any suitable manner. In the exemplary embodiment shown, it has a frame with a suitable conveying means (32), for example a circulating discharge conveyor. The removal device (18) may have a controllable drive, wherein preferably stands still during the material and pile storage. The material or pile storage of the one or more laying devices (16,17) can be done intermittently and in particular cyclically, in the laying breaks, when laying device (16,17) a new material and pile layer (9) is formed or provided the removal device (18) performs a conveying movement in the discharge direction (13). In FIG. 2 the discharge device (18) in an oblique orientation relative to the nonwoven layer (21) and the laying device (16,17) is shown.

The removal device (18) may further comprise a holding device (38) for the material and pile layers (9) and the fleece (8). This can be configured in any suitable manner, for example as a suction device, wherein the suction takes place under the corresponding air-permeable conveyor or discharge belt (32). Furthermore, a cutting device for trimming the nonwoven edges may be present on the removal device (18).

The laying device (16, 17) can be designed differently. FIG. 2 and 3 show a preferred embodiment with a design as a nonwoven layer (21). This may comprise a plurality of carriages (24,25,26) and a plurality, in particular two circumferentially driven conveyor belts (22,23), each arranged in a closed loop and at least partially closely adjacent to each other, wherein they supplied in this area Pick up and guide tray material (5,37) between them. The conveyor belts (22,23) are guided by rotatable rollers on the carriage (24,25,26).

At least a portion of the carriage (24,25,26) is movably mounted on a machine frame and suitable guides in feeding and laying direction (7). The nonwoven applicator (21) is designed as a so-called stripper and has a movable superstructure (24) on which the conveyor belts (22, 23) are brought together from different directions. On the one conveyor belt (22) from the feed (14) coming filing material (5,37) is received. The conveyor belts (22, 23) can be guided via one or more, in particular two auxiliary carriages (26), which can also be moved in the direction (7), with which differences in length in the belt loops formed are compensated. The conveying or laying belts (22,23) are guided in parallel position with the guided between them storage material (5) to an adjacent undercarriage or laying carriage (25), where the conveyor or laying belts (22,23) again separated from each other and both sides be led away, wherein the laying carriage (25) the released storage material (5) exits downwards. The laying carriage (25) can also be moved in the direction (7). It can alternatively be arranged stationary.

The nonwoven layer (21) is the deposition material (5,37) intermittently and cyclically from, in the laying or dispensing breaks the discharge device (18) a Conveyor movement performs. The storage material (5) is fed constantly on the input side. The laying device (2) has a storage device (15) which temporarily stores the deposit material (5) in said laying breaks. In the illustrated embodiment, the material reservoir (15) is formed by a conveyor belt section (27) having a variable length. A first section is formed by the conveyor belt (22) between the superstructure (24) and the material entry point or the connection point to the feed (14). The second variable section is formed between the two main cars (24,25). FIG. 2 and 3 make it clear that the length of the belt section (27) and thus the size of the material reservoir (17) is changed by the travel of the upper carriage (24), wherein the auxiliary carriage or carriages (26) receive the correspondingly varying remaining strap loop length. The carriages (24,25,26) and the levers (22,23) have suitable controllable drives.

In another embodiment, not shown, a material or storage store may be placed in front of the laying device (16, 17), e.g. in the region of the feed (14), be arranged.

In a non-illustrated embodiment, the nonwoven layer (21) can deposit the deposition material (5, 37) exiting on a mobile laying carriage (25) directly onto the removal device. A separating device (19) can in this case be arranged in the region of the laying carriage (25) or elsewhere within or in front of the laying device (16, 17). The laying carriage (25) reciprocates over the removal device (18) in the direction of laying (7), stopping at the ends of its movement path and stopping the material outlet on the laying carriage (25), wherein a continuously fed deposition material (5, 37) ) is recorded in the memory (15) and then emptied at the next carriage movement. The laying carriage (25) can Lay down material or pile layers (9) during forward and reverse travel. As an alternative, it can only deposit in one direction of travel, with the material store (15) being filled when traveling in the opposite direction. In the various variants, an intermittent or intermittent storage takes place on the discharge device (18).

FIG. 2 and 3 show a variant of the laying device (16,17), in which an intermediate carrier (20) is arranged between the nonwoven layer (21) and the discharge device (18), which discharges the discharge material (5,37) emerging at the stationary carriage (25). in an overhead receiving area (35) receives and delivers in a lower discharge area (36) to the discharge device (18). Here, a lifting device (31) for mutual approach of intermediate carrier (20) and discharge device (18) may be present, which is associated with the discharge device (18), for example.

In FIGS. 4 and 5 the details of the intermediate carrier (20) are shown in different operating positions and in a broken and shortened end view.

The intermediate carrier (20) may be arranged to be height-adjustable stationary or by means of said lifting device (31). It consists of a frame (28) with a conveyor (29) for receiving and transporting the storage material (5,37) or a material or pile layer (9). The conveyor (29) can be designed, for example, as a conveyor belt running around the box-shaped frame (28) on the outside and have a controllable drive. On the one frame side, where the deposition material (5,37) is guided around, an upper and a lower deflector (34,35) for the conveyor (29) may be present, wherein the lower deflector (34) projects further radially than the upper deflector (33), causing a sloping is formed outwardly sloping conveyor belt section.

The intermediate carrier (20) may comprise a holding device (30), which may be e.g. is arranged in the frame (22) and which can control the release material (5,37) hold and release. The holding device (30) may be e.g. be designed as a controllable suction device, wherein the conveying means (29) and possibly also the deflections (33,34) are designed to be permeable to air. It can also be multi-part or variable in order to be able to act on different subcarrier areas differently.

On the intermediate carrier (20), a separating device (19) is arranged in this embodiment, which forms a singulated material or pile layer (9) from the web-shaped supplied depositing material (5, 37). The separating device (19) can be designed in different ways, for example as a cutting device or as a tearing device. FIGS. 4 and 5 show both variants.

In FIG. 4 shows the one variant of a cutting device, wherein the separating device (19) is located on the aforementioned oblique band portion between the deflections (33,34). The cutting device here picks up the deposit material (5, 37) from the conveyor belt section to form a loop or a hump, in which a cutting tool, eg a rotating knife, can cut through the exposed material web (5). In this case, a pulling cut can be made, whereby the material or pile layer (9) receives an oblique edge. The cutting process can be done during material transport.

In the variant of FIG. 5 the separating device (19) is designed as a tearing device and is located on the underside of the intermediate carrier (20). It can for example consist of two clamping bars or other clamping or gripping means which grip the storage material (5) and themselves move apart, the web is stretched and torn. The bars or the like can be aligned in the alignment angle (α, β).

The aforementioned clamping bars, pinch rollers or the like. Other retaining means may also be present in the first variant with the cutting device. They serve here for fixing and positioning the front region of the material web (36) remaining on the conveying means (29). They can do the same function in the second variant of FIG. 5 fulfill.

In FIG. 2 and 3 the laying carriage (25) is positioned at an edge region of the intermediate carrier (20). FIGS. 4 and 5 show a modification with a displaced in the middle subcarrier area carriage position.

In all embodiments, the depositing material (5, 37) exiting on the laying device (16, 17), in particular on the carriage (25), is received on the revolving conveyor (29), the circulating speed essentially being the outlet speed at the laying device (16, 17). or carriage (25). The recorded storage material (5,37) is thereby held by the holding or suction device (30) during transport.

In an intermediate carrier region between the receiving region (35) and the lower delivery region (36), the material web (5, 37) is separated with the separating device (19). The isolated material or pile layer (9) is then brought by a corresponding conveying movement of the conveying means (32) in a dispensing position at the lower dispensing area (36). The initial area of the remaining material web (5, 37) can follow.

Subsequently, from the standstill position of the conveyor (29) and the discharge device (18), the position transfer, possibly with the cooperation of the lifting device (31). When the holding device (30) is switched off, the intermediate carrier (20) releases the material or pile layer (9), which thereby falls on the rear fleece region and is held here by the holding device (38). In this time, the pile memory (15) is filled. Subsequently, the discharge device (18) clocks forward, wherein the conveying means (29) of the intermediate carrier (20) is set in motion again and discharge material (5) is placed on the receiving region (35) again emptying the paper store (15). Then the cycle repeats itself again.

As FIG. 6 clarified, at a deviating from 90 ° alignment angle (α, β), the material or pile layers (9) have a trapezoidal shape and are separated for this purpose obliquely. This gives lateral side edges (12), which are aligned parallel to the discharge direction (13) and obliquely to the discharge direction (13) extending front and rear parallel edges (10,11) have. At the aforementioned position conclusion of the conveyor cycle is tuned so that the said edges (10,11) come in shingled layers (9) on top of each other to cover.

Variations of the embodiments shown and described are possible in various ways. A laying device (16, 17) can also be configured in another way, for example as a wagon loader, camelbacker or the like. The intermediate carrier (20) can also be combined with other variants of the laying device (16, 17). Furthermore, the above-described features of the various embodiments can be combined with each other and exchanged.
