Description

DESCRIPTION

Fleece layer

The invention relates to a fleece layer with the features in the preamble of the main claim.

Such a nonwoven layer is known from FR-2 553 102. The non-woven layer, which is designed as a so-called tape layer, has two main carriages which are movable relative to one another and two endless and rotatingly driven laying bands which are guided in loops. The laying tapes run parallel, at least in the section between the main carriages, taking up and guiding the pile between them. On the input side, the fleece layer has a so-called tape inlet for the laying tapes. The laying tapes brought in from two sides meet here and are brought together to form an inlet slot. The pile fed on the one laying tape is deflected downwards in the tape inlet. in the

Tape entry, the two laying tapes have two straight tape sections running parallel to one another, which form the said slot. In the prior art, these belt sections extend vertically downward, as a result of which the horizontally fed pile at the belt inlet is deflected by 90 °. In practice, it has been shown that such a tape inlet can only be used for limited feeding speeds of the pile and working speeds of the nonwoven layer. If the feed speeds become too high, the very light and highly sensitive fibrous web may tear.

Recent developments, e.g. according to EP-A-0 517 568 tend to create a very wide and wide opening inlet funnel before the tape entry. Here the laying tape feeding the pile has a slant

ORIGINAL DOCUMENTS sloping belt section, on which the pile is transported open. Only at the lower end of the band section does the second laying tape come up, which means that the pile only gets into the belt run at this point between the two laying tapes and is only picked up and guided on both sides by the laying tapes at the tape deflection. Here, too, the belt run is arranged on the upper main carriage and is therefore movable.

WO 91/156018 shows a further variant of the

Belt run, in which both laying tapes on the main carriage are guided over two large deflection rollers. This also forms a further emptying funnel for the pile fed on the one laying tape. The two large deflecting rollers are arranged horizontally next to one another at approximately the same height, as a result of which the pile is picked up and guided on both sides only approximately at the midpoint height of the two rollers by the laying tapes that come close together here. Before and after, the laying tapes come apart again due to the roller shape. These two aforementioned fleece layers are designed for higher feed speeds of the pile and processing speeds of the fleece layer. However, due to the fact that the laying tapes are only brought together point-by-point or line by line and the correspondingly short guide length, there are problems limiting the speed.

From DE-A 19 27 863 and DE-A 24 29 106 fleece layers with stationary strip inlets are also known, in which the laying strips are guided over stationary deflection rollers. Both fleece layers show horizontal belt runs.

In DE-A 24 29 106, the two laying tapes form a horizontal emia slit, which connects to the feed belt coming from the card. On the upper main carriage, the tapes are separated from each other, whereby the pile is deflected downwards by 90 ° and is only transported and guided on the laying tape below. In DE-A 19 27 863, the pile is fed via a stationary upstream conveyor belt and, in free fall, is brought to an underlying somewhat sloping laying belt section before the belt run. The second laying tape is only a little behind this point. The inlet slot is created very late at the deflection point in the following horizontal emi stretch of the belt run. Both embodiments with the stationary belt run limit to a considerable extent the speeds of the pile feed and fleece layer.

It is an object of the present invention to

To show fleece layers with an improved belt run.

The invention achieves this object with the features in the main claim. In the belt run according to the invention, there is an inclined downwardly inclined inlet section which is formed by two belt sections running close to one another, which take up and guide and / or cover the supplied pile on both sides, forming an inlet slot. The belt sections are directed obliquely downward at an obtuse angle against the feed or infeed direction. This has the advantage that the pile deflection takes place more gently and the centrifugal forces acting do not become too great. Thanks to the inclined position, the overhead band section can act as a cover for the pile at the deflection and prevent the pile from being lifted off by centrifugal forces, wind effects, etc. The belt run according to the invention ensures particularly gentle and safe picking up and guiding of the pile. It allows much higher tape speeds and

Pile feed speeds while maintaining high functional and operational reliability. The belt sections are preferably straight and can run essentially parallel over a certain distance. Alternatively, an inlet section that narrows in a funnel shape is also possible. In the inlet section, the pile can either be guided without compression or gradually pressed together or clamped. Due to the funnel-shaped inlet section, the snowing pile is safely grasped and the air contained therein is gently pressed out over a longer distance and time period. Abrupt pinching points, rapid air currents and turbulence that could damage or destroy the pile are avoided. It is advantageous if the inlet section is essentially straight.

The sloping inlet section gently picks up the pile at the top and only redirects it sharply at the bottom. It is advantageous to provide at least one strap loop at the lower deflection point. In a particularly advantageous embodiment, at least two belt loops are present, the first belt loop being arranged in front of the deflection point and the second belt loop being arranged behind it. As a result, disturbing at the critical points of the redirection

Relative speeds of the laying tapes or their tape sections prevented. As a result, the pile can be deflected particularly safely and unloaded. The pile is preferably clamped at three or more points in the deflection area by deflection rollers.

In order to adapt to the different conditions of use of the fleece layer, varying pile types, etc., there are various setting options at the belt inlet. In particular, the width and possibly also the inclination of the inlet section can be changed. The adjustability of the spacing of the tapes enables exact adjustment to the pile thickness and the setting of the friction conditions necessary for the transport of the pile. Depending on the design of the belt infeed, a preferred possibility of adjustment lies in the delivery of the different deflecting rollers or in a plate-like support device. In addition, other design variants are also possible.

The belt run can be stationary or mobile. In the preferred exemplary embodiments, it is located in front of or on the upper main car.

The outlet section running between the uppercarriage and the laying carriage can also run at an angle to the horizontal. This allows more

Reduction of the deflection angle of the pile in the superstructure and a reduction in the centrifugal forces acting on the pile in the deflection area.

The lower laying tape in the infeed section can run in a straight line in front of the infeed section. The pile is transferred from this feed belt to this laying belt. Alternatively, the lower laying tape in the inlet section can also be designed as a feed belt. In this case, the lower laying tape can be deflected twice in order to form the inlet gap before the inlet. The design of the lower laying belt at the same time as a feed belt saves some rollers and drives and is therefore less expensive.

Before the tape entry, a pressure roller, preferably a screen or perforated roller, can rest on the pile, which serves to remove air from the pile.

In an alternative embodiment, the

The feed section and the inlet section are on a common plane. This plane is around relative to the horizontal inclined downwards towards the superstructure. With such an entry zone, the pile is not deflected unnecessarily and can be fed straight to the superstructure.

Further advantageous embodiments of the invention are specified in the subclaims.

The invention is shown in the drawings, for example and schematically. In detail show:

FIG. 6: a further alternative exemplary embodiment to FIGS. 4 and 5, in which the lower laying belt is at the same time the feed belt.

Figures 1 and 3 show an overview of a fleece layer (1), which is designed as a so-called tape layer. It has an upper main carriage (2) and a lower main carriage (3) in a housing or frame (54) and can also have one or more auxiliary carriages or tensioning carriages (32, 34). Two endless laying tapes (5,6) are guided over the carriages (2,3,32,34) by means of suitable rollers. At least the two main carriages (2, 3) are driven to move back and forth by suitable drives. The two

Laying tapes (5, 6) are also driven in a rotating manner by means of suitable controllable and adjustable drives. The fibrous web (7) produced by a pile producer (not shown), for example a card or card, arrives in the nonwoven layer (1) via a feed belt (25). It is led via a feed section (26) to or on the upper main carriage (2) and passes between the two laying belts (5,6) at the belt inlet (4,9) described in more detail below. The latter are guided in a loop parallel to one another at least in the area between the two main carriages (2, 3) and take the pile (7) between them, transport and guide it. This loop area is referred to as the runout section (27). It can extend horizontally or diagonally and connect the main carriage (2, 3) directly or via a frame-fixed deflection (not shown). The outlet section (27) preferably runs in a straight line.

At the lower main carriage (3), the so-called laying carriage, the pile (7) emerges downwards and is laid down on a transverse, endless draw-off belt (8) to form a fleece (23). The laying carriage (3) travels back and forth over the take-off belt (8), as a result of which the pile (8) is deposited in several layers one above the other and zigzag to the direction of delivery. The pile (7) is paneled like scales. The laying tapes (5, 6) separate again on the laying carriage (2) and are separated outwards in separate loops and then returned to the tape inlet (9).

For the constructive training and function of the

Fleece layer (1), there are various possibilities, such as are known from the prior art mentioned in the introduction to the description. The two main carriages (2, 3) can form a short passage in the same direction as in DE-A-19 27 863 or EP-A-0 517 568 or in opposite directions with stationary belt deflection as in FR-A-2 553 102 or the WO 91/156018 move. Internal storage can be formed by means of auxiliary or tensioning carriages (32, 34) to influence the pile placement on the draw-off belt (8). It is also possible to work with delay when laying the pile to set a specific thickness profile of the fleece (23).

In the fleece layer of Figures 1 and 2, the belt inlet (4) is movable and is located on the superstructure (2). It has a comparatively short inlet section (9) with a fixed length. Figures 3 to 6 show a variant with a stationary belt run (4), which is arranged in front of the superstructure (2). Here the inlet section (9) is larger and has a variable length.

Figure 2 illustrates the belt run (4) of the fleece layer (1) of Figure 1 in detail. In this embodiment, the belt run (4) is located on the upper main carriage (2). At the belt inlet (4), the two laying belts (5,6), which are guided separately behind the laying carriage (3), meet, then run close together and pick up the pile (7) fed in from the outside. In the embodiment shown, a laying tape (5) also serves as a pile feeder (25) and is accordingly led out of the housing (54) of the fleece layer (1). The pile (7) lies open on the laying tape (5) and is transported by it to the tape inlet (4).

The two laying tapes (5,6) are formed on the belt run (4), forming a narrow inlet slot (12)

Deflection rollers (14, 16) brought together. The deflection rollers (14, 16) are followed by the inlet section (9), which is formed by two essentially straight belt sections (10, 11) of the laying belts (5, 6) up to a further deflection (15). The band sections (10, 11) take up the pile (7) between them and cover it or run it along both sides of the Inlet section (9).

The inlet slot (12) has an adjustable width that can be adapted to the particular requirements of the pile material. It is preferably somewhat larger than that

Is pile thickness, so that the loose pile (7) can initially be picked up without being forced or compressed. However, the width can also be equal to or less than the pile thickness sem and possibly lead to a clamping as soon as the pile (7) enters the belt run (4).

The band sections (10, 11) run essentially parallel. This can be strictly parallel. As an alternative, the distance can also decrease via the running direction (24). This forms a funnel-shaped tapering inlet section (9), in which the pile (7) is gradually pressed together and clamped before it reaches the lower deflection (15). In this variant, it may be advantageous to set the width of the inlet slot (12) greater than the pile thickness. However, it is also possible, with a small slot width, to clamp the pile (7) as soon as it enters the belt run (4) and to increase the compression further over the length of the run-in section (9). The choice of the appropriate setting depends on the type of pile material and, if appropriate, also on the pile feed speed and / or other parameters.

The inlet section (9) or the band sections (10, 11) forming it are inclined obliquely downwards at an obtuse angle β relative to the horizontal or the feed or inlet direction (24). This obtuse angle β relates in Fig. 1 to the belt deflection of the laying tape (5) on the deflection roller (14). The preferably horizontal feed path (26) of the

Laying tape (5) is deflected m the sloping tape section (10). The obtuse angle ß between the band areas is larger than 90 ° and smaller than 180 °. It is preferably approximately 135 °.

At the lower end of the inlet section (9) the pile (7) and the laying tape (5,6) are again deflected in a preferably horizontal direction and reach the laying carriage (3) via the outlet section (27). At the belt run (4) there is thus a total deflection of the pile (5) or the laying tape (5, 6) by 180 °. Due to the slope of the inlet section (9), the deflection is weaker at the upper end and stronger at the lower end. Due to the belt run (4), the pile (7) in front of the lower, stronger deflection (15) is already guided and covered over a long straight distance and does not suddenly reach the clamping point on the deflection (15).

The laying belt (5) is guided over two deflection rollers (14, 15), which are preferably arranged in a relatively stationary manner on the upper main carriage (2). The guide rollers (14, 15) smd corresponding to the slope of the inlet section (9) m of the height and laterally spaced.

The upper deflecting roller (16) of the other laying belt (6) is arranged above the opposite deflecting roller (14). The connecting line of the two roller axes runs approximately perpendicular to the inclination of the emia run (9).

At the lower end of the emia run (9), the laying tape (6) has two or more tape loops (13). The one

Belt loop (13) is located in front of the deflection point formed by the deflection roller (15) and the second belt loop (13) behind it. Via the belt loops (13), the laying tape (6) located at the top or outside in the belt run (9) is detached from the pile (7) at the critical deflection points. The detachment avoids different belt speeds in the area of the deflection. The two laying tapes (5, 6) move with the pile in between about the axis of the deflection roller (15). Due to its greater distance from this axis, the laying tape (6) above should actually have a higher relative circulation speed in order to be able to drive the pile (7) over the entire deflection area without tension. However, the two laying tapes (5,6) have the same rotational speed. The two belt loops (13) eliminate the problem.

The first band loop (13) is formed by deflecting rollers (17, 18, 19). The first deflection roller (17) sits at the lower end of the belt section (11) and is located above the deflection roller (15). It is arranged so that the connecting line between the two roller axes is oriented approximately perpendicular to the inclination of the inlet slot (12). The laying tape (6) or its top band section (11) is thereby detached from the pile (7) approximately at a point at which the bottom band section (10) gets onto the deflection roller (15). As a result, the pile (7) comes into the deflection area on the roller (15) without distortion.

The laying tape (6) is pulled out to the belt loop (13) via the deflecting roller (19) which is offset obliquely to the rear and then returned to the deflecting roller (18). The latter is essentially at the same height as the deflecting roller (15) and has approximately the same diameter. As a result, the two laying tapes (5, 6) come together again at about the height of the two rollers (15, 18) and can move the pile (7) between them. They have essentially the same running speed, which is also the same as the pile speed. Behind the deflection roller (18) sits the second belt loop (13), which is pulled out by a laterally offset deflection roller (20). Their diameter is such that the laying tape (6) is then deflected into a horizontal section running parallel to the laying tape (5). In this subsequent horizontal section, the two laying bands (5, 6) are again so close together that they guide the pile (7) between them on both sides.

Below the deflecting roller (15) a support device, e.g. a support roller (21) for the laying tape (6) can be arranged. The support roller (21) influences the spacing of the laying belts (5, 6).

Due to the roller arrangement shown, the pile (7) in the region of the lower deflection on the deflection roller (15) is clamped or clamped at three points between the laying belts (5, 6) and is therefore guided reliably and at the same belt speeds. At the end of the inlet section (9) the guide between the belt sections is sufficient

(10,11) just until the lower deflection roller (15) is reached. Then there is again a double-sided guidance about m height of the axes of the deflecting rollers (15, 18). The third guide point is located at the end of the deflection between the deflection roller (15) and the support roller (21), which is preferably located vertically below it. At this point, the laying tape (5) leaves the deflection roller (15) again.

The belt inlet (4) and the inlet section (9) are adjustable. For example, the position of the deflecting rollers (16, 17, 18) and the support roller (21) can be changed with suitable feed devices (22). The feed direction for the deflecting rollers (16, 17) located in the region of the inlet slot (12) is preferably substantially perpendicular to the direction of the inlet section (9). This allows the width of the Inlet slot (12) and possibly also the funnel-shaped narrowing of the inlet section (9) can be changed. The laying tapes (5, 6) can be permeable to air, so that the pile becomes compressed due to the increasing narrowing of the inlet section (9) and the air contained therein is pressed out.

The deflecting roller (18) is preferably horizontally adjustable and can thus be approximated or removed in relation to the deflecting roller (15) of the laying belt (5). This affects the second guide point for the pile (7) in the lower deflection area.

The support roller (21) is vertically adjustable and can therefore also be approximated or removed from the deflection roller (15). With the support roller (21), the pile guidance at said third guidance point is influenced.

The direction of travel of the pile (7) or the laying tape (5) feeding it in the area of the tape inlet (9) is marked by arrows (24).

Modifications of the embodiment shown are possible in m different ways. In the shown

In the exemplary embodiment, the two band sections (10, 11) receiving the pile (7) begin at approximately the same height at the entrance to the inlet slot (12). Alternatively, the overhead belt section (11) can also be drawn somewhat higher and, if necessary, protrude beyond the deflection point on the roller (14). For example, this is useful for catching a very fast-moving pile. The band section (11) can also be arranged somewhat lower. The design, number and arrangement of the belt loops (13) at the lower end of the inlet section (9) can also be changed. For example, there may only be one lower belt loop (13). The setting and Possibility of delivery of the individual deflecting rollers or other belt-guiding parts on the belt run (4). The inlet section (9) can also be somewhat curved.

In the alternative shown in FIG. 3

Exemplary embodiment, the fleece layer (1) has a separate feed belt (25), via which the pile (7) is fed from a card arranged in front of it at a uniform but variable speed. The fleece layer (1) is in turn equipped with four carriages, namely an upper carriage (2), a laying carriage (3) and in each case a tension carriage (32, 34) for each laying belt (5, 6).

The first laying belt (5) takes over the pile (7) from the feeding belt (25) in the area of the feed section (26) and guides the pile (7) into a fixed belt run (4) between the two laying belts (5, 6) extends to the superstructure (2) and the deflection there (15). The fixed belt run (4) is arranged near the end of the movement path of the superstructure (2) approximately in the middle of the laying width of the fleece layer (1). The laying tape (5) is fed to the belt conveyor (4) as the lower laying tape, while the upper laying tape (6) is fed via a deflection roller (16).

The stationary deflection roller (16) has a considerably larger diameter than the other deflection rollers, as a result of which a discharge funnel is formed on the belt run (4). The laying tapes {5, 6) have a distance at the belt run (4), for example, which is greater than the pile thickness. The emia slit (12) formed in this way initially allows the web (7) to run without any significant clamping or compression. Below the lower laying tape (5) there is a height-adjustable support device (21) with which the gap width of the inlet slot (12) can be adjusted. Between the inlet slot (12) and the superstructure (2) extends the substantially straight inlet section (9), in which the tape sections (10,11) of the laying tapes (5,6) gradually converge so that they are at the end of the Inlet section (9) on the superstructure (2) have a distance that is adapted to the pile thickness. This distance can correspond, for example, to the pile thickness or can be set to a fixed value, for example 15 mm. The pile (7) is gradually guided and covered on both sides in the funnel-shaped narrowing inlet section (9). This can be done without compression. Alternatively, the pile (7) in the inlet section (9) can also be gradually compressed and clamped. The inlet section (9) changes its length with the movement of the superstructure (2).

In the superstructure (2), the upper laying tape (6) is deflected several times over a guide roller (17) and over the rollers (18, 19, 20), as in the exemplary embodiment described above, to form two belt loops (13), so that the pile ( 7) does not run in the deflection area on the superstructure (2) between the two laying bands (5, 6). Only below the deflecting roller (15) for the lower laying belt (5) is the pile (7) in turn guided between the two laying belts (5, 6). The laying belt (5, 6) can be supported on the roller (56) of the laying carriage (3).

The outlet section (27) located between the superstructure (2) and the laying carriage (3) preferably runs in a straight line, the pile (7) emerging after a further deflection by 90 ° in the laying carriage (3) at an exit point and from which it moves back and forth Laying trolley (3) is placed on the discharge belt (8). The laying carriage (3) also has a guide roller (56) for the laying belt (5) which, after being deflected twice via the deflection rollers (60, 62), is returned to the strip inlet (4) via further deflection rollers. The laying tape (6) will deflected via a deflection roller (58) and returned to the belt conveyor (4).

The inlet section (9) and / or the outlet section (27) preferably run obliquely downward at an obtuse angle β to the horizontal in the direction of movement (24) of the laying tapes (5, 6). As in the first exemplary embodiment of FIGS. 1 and 2, this angle is between 90 ° and 180 ° and is, for example approx. 170 °.

A tensioning carriage (32) is provided for the laying belt (5) and is controlled as a function of the movement of the laying carriage (3). For the laying tape (6), a tensioning carriage (34) is provided, which is controlled as a function of the movement of the uppercarriage (2) and the laying carriage (3).

The movement of the tensioning carriage (34) is positively controlled with the aid of toothed belts.

The tensioning carriage (34) is arranged in the direction of rotation of the laying belt (6) behind a stationary deflection roller (36) and the further stationary deflection roller (16) on the belt run (4).

FIG. 4 shows the belt run (4) on an enlarged scale, a pressure roller (30) consisting of a perforated or screen roll being able to pre-compress the pile (7) in front of the run-in slot (12). The pressure roller (30) can be held at a predetermined distance from the lower laying tape (5).

FIG. 5 shows an alternative exemplary embodiment, in which the lower laying belt (5) in the inlet section (9) also serves as a feeding belt (25). A feed section (26) located in front of the advance section (9) before the belt run (4) lies in the same plane as the inlet section (9) and is inclined downwards relative to the horizontal in the direction of movement of the laying belt (5). In this embodiment, the pile (7) in the feed zone and in the inlet section (9) to the superstructure (2) is no longer deflected.

FIG. 6 shows a further exemplary embodiment, in which the lower laying belt (5) also serves as a feed belt (25). In this case, the laying tape (5) is deflected several times over the deflecting rollers (38 to 40) so that the laying tape (5) can be fed to the inlet section (9) at a distance from the laying tape (6) to form the inlet slot (12) . Instead of the support device (21), the deflection roller (39) can be adjustable in height.
