Definitions
- the invention relates to a fleece guiding device for a textile machine with a drafting device for compacting a nonwoven fabric leaving the drafting device in a spread form with an inlet section and a subsequent outlet section which has a cross section narrowed compared to the inlet section.
- the invention also relates to a textile machine with such a fleece guiding device.
- the Rieter company for example, is a drafting machine that extends across the web
- Fleece funnel is sometimes also referred to as a fleece guide nozzle.
- a fleece nozzle insert which is elongated in the fleece transport direction can be inserted into the fleece funnel, the fleece leaving the fleece funnel through its outlet section and through the
- Fleece nozzle insert reaches a belt funnel.
- the belt funnel protrudes into a gap formed by downstream calender rolls, the
- Fiber fleece or the fiber sliver formed from the fleece in the sliver funnel is pressed between the calender rolls and drawn off from the sliver funnel.
- a disadvantage of the known construction is that fibers lying further outside in the fleece do not run directly into the fleece guide nozzle after leaving the drafting system, but rather hit the baffle surface of the fleece funnel at high speed, are folded in there and deflected to the fleece nozzle insert.
- This abrupt impact on the one hand disturbs the previously precisely warped fiber fleece, on the other hand the fibers lying outside in the fleece cover a greater distance than the ones lying inside, which are transported directly to the fleece nozzle insert.
- the fibers of the nonwoven are again, but this time undesirably, shifted against each other.
- Another consequence is that the parallelization of the fibers is deteriorated, particularly in the case of combed slivers.
- a textile machine according to the invention with a drafting system is characterized by a corresponding fleece guiding device.
- the fleece guiding device is characterized in particular by the fact that outer fibers lead to the outlet section in a more direct way or with less detours than those lying further inside. All fibers of the nonwoven are preferably guided from at least one guide surface to the outlet section, so that the fibers lying inside are also guided, and not directly. The inside fibers are thus not transported in the shortest possible way from the exit rollers of the drafting system or a deflection top roller to the outlet section and further into a fleece nozzle section or a belt funnel.
- the distance covered by the fibers lying further inside in the fleece is thus artificially lengthened so that an offset of the fibers of the fiber fleece between the drafting system outlet and the calender rolls is kept low or even avoided entirely. Accordingly, it is expedient to guide the fibers lying on the outside in an almost direct way or in a slight curve to the outlet section, while the central fibers located in the middle advantageously cover an arcuate path.
- the high warping quality of the fleece at the exit of the drafting system and possibly also the parallelization of the fibers of the fleece leaving the drafting system can be maintained. Overall, a sliver results in higher uniformity than in the prior art.
- the at least one guide surface is designed such that the distances of all fibers from the outlet of the drafting system to the outlet section are essentially of the same length, so that no displacement of the fibers occurs after leaving the drafting system.
- mathematical modeling has been carried out.
- the guide surface can be designed similar to the inner surface of a shell or a baseball glove in order to meet the requirement of equally long distances.
- the guide surface advantageously extends following the output roller of the drafting system over the entire width of the fleece.
- the lateral sections of the guide surface lead essentially straight to the exit section.
- the corresponding surface section for the fibers lying inside is made concave or bulbous, the largest curvature being provided for the central or central fibers.
- the fleece guiding device is advantageously arranged or can be arranged immediately behind the last drafting roller or the last pair of drafting rollers, so that the fibers can be guided immediately after they have left the drafting arrangement.
- the fibers can also be guided continuously.
- the direction of the fleece is inclined when leaving the drafting device with respect to the axis of the downstream belt funnel; for example, the drafting system is designed to be horizontal or inclined, while the belt hopper is oriented vertically.
- the at least one guide surface according to the invention is preferably designed in such a way that on the one hand it realizes the corresponding deflection of the fleece and on the other hand completely avoids the fiber offset across the fleece width at least partially and in a particularly preferred case.
- the drafting system is arranged vertically, so that, in the case of such conventional drafting systems, the fleece runs downward into the belt funnel without substantial deflection from the fleece plane (based on the direct exit from the drafting system). Accordingly, the configuration of the at least one guide surface according to the invention is to be adapted, which essentially has the task of at least partially avoiding the fiber offset.
- the fibers can preferably be guided between at least two guide surfaces, wherein these can be arranged opposite one another or offset in the direction of the fleece.
- at least part of the fleece can first be guided along one guide surface and then along the other guide surface.
- the inner fibers of the fleece in particular are guided over a curved guide surface and thus deflected out of the way to the belt funnel until they are guided back to their original path to the belt funnel by a further downstream guide surface.
- guide surfaces are preferably of this type formed and arranged that at least the inner fibers are guided along a concave guide surface at faster delivery speeds and substantially along a convex guide surface at lower delivery speeds.
- the inner fibers leaving the drafting system are thus guided along the concave surface.
- the inner fibers are not conveyed against this concave guide surface, but would move in a more direct way to the fleece nozzle. It is therefore advantageous to deflect these fibers from the other side at the low delivery speeds mentioned.
- the inner fibers are preferably guided along the convex guide surface and in this way also reach the exit section in a deflected manner according to the invention.
- the entry section and the exit section as well as the at least one guide surface are formed in one piece.
- a multi-part training can be useful if more than one guide surface is provided.
- the individual parts of the fleece guiding device can be separated from each other, for example, such that e.g. the threading process for a fleece end is facilitated.
- the position of the at least one guide surface can be changed.
- the fleece can run over the convex guide surface mentioned, which can then be pivoted away at higher speeds, for example. This measure can help prevent the formation of air vortices or blockages of the device with fiber material.
- a simple threading of the fleece end can also be realized if the threading cross section is briefly increased by changing the position of the at least one guide surface.
- Such a change in position is preferably implemented by a swivel mechanism.
- a control device can also advantageously be used be provided, which, depending on the delivery speed, issues an adjustment instruction for the respective positioning of the guide surface.
- the nonwoven guide device is designed in such a way that all or part of it in the event of a tape jam and / or in the event of winding formation on one of the exit rollers and / or for easier access to the elements downstream of the nonwoven guide device, for example a nonwoven nozzle or a belt funnel, is pivotable from an operating position into a maintenance position for the purpose of easier threading. If necessary, further elements for fleece forming or band formation can also be given away, for example fleece nozzle elements or a band funnel.
- openings can be provided, which can be used in particular for removing and / or supplying air.
- these openings can be made very small and vacuumed in order to ensure that the fibers lie evenly along the guide surface.
- openings can be used to impart a movement component to the fibers in the direction of the outlet section. It can also be provided that openings for air supply are provided in one section or openings for air discharge in another section. Openings can also be used to prevent the formation of air vortices within the fleece guiding device.
- the fleece guiding device advantageously encloses the fibers at least in regions more than 180 ° and in a further advantageous embodiment completely at least in regions. Particularly in the transition area from the outlet section to a subsequent fleece nozzle or a downstream belt funnel, it is advisable for the fleece guide device to be arranged on all sides around the compressed fiber fleece.
- the fleece guide device is advantageously designed as a funnel or comprises such a funnel.
- a funnel is responsible for compressing the nonwoven fabric emerging from the drafting device and, as a rule, for feeding it to a downstream fleece nozzle and / or a belt funnel.
- Such a fleece nozzle, which may also be designed as an insert, and / or a downstream belt funnel are combined according to a further advantageous embodiment in the fleece guide device according to the invention.
- the at least one guide surface is preferably designed to be non-fibrous or slippery in order to avoid fiber deposits and to ensure undisturbed, uniform operation.
- Low-friction materials such as an enamel coating or polished stainless steel, are therefore preferably used for the guide surface (s).
- the corresponding material is preferably designed to be abrasion-resistant or wear-free.
- the invention also comprises a textile machine with a drafting system, which comprises a fleece guiding device according to the aforementioned. Due to the guidance of the fibers according to the invention, there is also no need for a top deflection roller, as is used on most common routes. The deflection can be completely taken over by the at least one guide surface according to the invention.

- FIG. 1 shows a schematic, sectional side view of a horizontal drafting device 1 with successive pairs of rollers.
- An input roller pair with an input bottom roller 2 and an input top roller 5 is followed by a middle roller pair with a middle bottom roller 3 and middle top roller 6.
- These two roller pairs form the so-called pre-drafting field, which is followed by the main drafting field, which consists of the above-mentioned center roller pair and an output roller pair with an output bottom roller 4 and an exit top roller 7 consists.
- a pressure rod 8 is arranged in the main drafting zone and serves to guide non-clamped, so-called floating fibers in the main drafting zone.
- the fiber fleece to be drawn in the drafting device 1 is identified by the reference symbol V.
- One or more slivers B can be fed to the drafting device 1 in a spread form.
- the drafting device 1 can be part of a card, a draw frame or a comber. It is irrelevant to the invention whether the drafting device 1 is adjustable.
- a fleece guiding device 20 Downstream of the drafting system 1 is a fleece guiding device 20 according to the invention in accordance with a first embodiment, which is shown in a perspective view in FIG. 2.
- This fleece guiding device 20 is formed in two parts and consists, on the one hand, of a funnel 21 and a ball-shaped body 31, the body 31 projecting centrally into the funnel 21.
- the funnel 21, which is shown in more detail in FIGS. 3 to 5, is designed to be open towards the drafting system 1 and has edges 27a rising on both sides, which are connected to an essentially straight upper edge section 27b. At the lower edge, the funnel 21 has a recess 27c through which a double-curved holder 35 for the body 31 runs.
- the overall result is a compact appearance of the funnel 21, which accordingly has a wide inlet section 22 for receiving the nonwoven fabric V emerging from the drafting device 1.
- an outlet section 24 which, in the exemplary embodiment shown, is designed to be closed on the circumference and has a circular cross section.
- Another cross-sectional shape can also be selected, for example an elliptical one.
- the rear wall of the funnel 21 is designed to be inward (concave) toward the outlet section 24.
- the rear wall can also run out vertically or outwards (convex), as a result of which turbulence in the outlet section 24, which could produce a twist in the nonwoven fabric, can be reduced.
- the inlet section 22 is connected to the outlet section 24 via a continuous guide surface 23 of the funnel 21.
- the guide surface 23 is such formed that over the width of the inlet section 22 into the funnel 21 fibers on their way to the outlet section 24 cover substantially equal distances.
- the fibers of the nonwoven fabric V are guided - provided the delivery speeds are sufficiently high - along the inner surface or the guide surface 23 of the funnel 21 to the outlet section 24 (see dashed line in FIG. 1).
- the design of the guide surface 23 is accordingly such that the fibers of the nonwoven fabric V lying further inside are deflected or deflected more than the fibers lying further outside.
- the fleece V leaves the drafting device 1 at a relatively high speed and is therefore conveyed to the guide surface 23, it first running into the funnel 21 essentially parallel to this guide surface in the region of the inlet section 22 and then is gently deflected to the outlet section 24.
- the speed impulse imparted to the fleece V is not sufficient to convey it to the guide surface 23. Rather, in this case the fleece V slides along the convex guide surface 33 of the body 31 opposite the guide surface 23 (see dotted line in FIG. 1) to the outlet section 24.
- the holder 35 for the spherical body 31 has at its foot an elongated hole 36 for receiving a screw, not shown, by means of which the relative position of the body 31 to the funnel 21 can be adjusted (see double arrow fi in FIG. 1).
- the thus adjustable penetration depth of the body 31 into the funnel 21 determines when the fleece V is supported by the guide surface 33.
- the funnel 21 has a widened foot 25 downstream of the outlet section 24, which is attached on the underside to a plate 9, the screw connections or the like not being shown in more detail.
- These recesses 1 can each receive a fixed axis, not shown, of a carrier unit arranged below it, so that the plate 9 can be pivoted, in particular in the event of a tape jam in the fleece guide device 20.
- the pivoting direction is indicated by the double arrows f 2 in FIGS. 1 and 2.
- a fleece nozzle 12 is arranged in alignment with the outlet section 24, which leads the compressed fleece V to a belt funnel, not shown.
- a belt funnel connects directly to the outlet section 24.
- FIG. 6 shows a drafting device 1 which is inclined downward in the nonwoven running direction and is otherwise similar to the drawing device 1 of FIG.
- This construction means that the fleece guide device 120 has a different geometry than that according to FIGS. 1 to 5.
- the funnel 121 as part of the fleece guide device 120 which is shown in more detail in a perspective view in FIG. 7, is less curved than the funnel 21 in Figures 1 to 5, but otherwise very similar in principle.
- the entry section 122 which extends across the fleece width, tapers on both sides almost linearly to the exit section 124, while the guide surface 123 is increasingly curved toward the center.
- a body 131 which is convexly curved towards the fleece V, has a flat cross-section and is designed to protrude into the funnel 121 and serves to guide the fibers at low delivery speeds (for example below 300 m / min). If the body 131 is not present, the funnel 121 is the only element of the nonwoven guide device 120. Downstream of the fleece guiding device 120 is a fleece nozzle 12 with an adjoining band funnel 14. Furthermore, openings 13 are provided laterally, obliquely downwards towards the center of the band funnel, through which air can escape from the compressed fleece V. Other options for air escape - at the entrance of the fleece nozzle 12 and already upstream in the fleece guide device 120 - are indicated by arrows.
- openings can also be provided in a known manner, which can be pressurized with compressed air in order to give the fleece V a pulse in the downstream direction. This measure supports the threading process of a fleece end in a known manner.
- the belt hopper 14 is followed by a pair of calender rolls 15, 16, which are known to serve for the removal of the fleece V through the fleece guide device 120 and for the further transport of the resulting belt to a belt channel and finally to a spinning can.
- fictitious lines 128 horizontally spaced apart in the direction of the fleece are shown on the guide surface 123. These lines 128 are all essentially of the same length and symbolize the distance covered by the fibers, regardless of their position across the width of the fleece, of essentially the same length.
- openings 129 are provided in the guide surface 123, which - similar to the exhaust air channels 26 according to the first embodiment - are designed to discharge air from the nonwoven fabric V. , Alternatively or - depending on the case of need - additionally compressed air can be introduced through these openings, which support the threading process of a fleece end.
- FIGS. 9 and 10 show a fourth embodiment of the nonwoven guide device according to the invention. This is used in particular with vertically oriented drafting systems, only the output roller pair 4, 7 being shown in FIG. 9.
- This pair of rollers 4, 7 is immediately followed by the - transparently shown - fleece guiding device 220, which is formed here in one piece and one has an elongated, slightly tapered shape in the direction of the fleece.
- the fleece guiding device 220 has a widened inlet section 222 opposite the rollers 4, 7 in order to be able to accommodate the entire width of the fleece V.
- an outlet section 224 with a round cross section is provided, which - similar to the construction according to FIG. 6 - is followed by a fleece nozzle 12, a band funnel 14 and calender rolls 15, 16.
- the fleece guiding device 220 has on one longitudinal wall an inwardly curved guiding surface 233, against which the fibers of the fleece V lying inside gently run to get out of their vertical Direction to be deflected (see dashed line in Figure 10).
- the outer fibers do not experience any deflection in the direction of the opposite wall, but are guided almost linearly to the outlet section 224 (see dotted line in FIG. 10).
- the area which is available to the nonwoven in the interior of the nonwoven guide device 220 is shown in dotted lines in FIGS. 9 and 10 (as well as in FIGS. 11 and 12).
- the fibers of the nonwoven lying further inside are first guided on the guide surface 233, which rises directly below the nip of the rollers 4, 7. Subsequently, these fibers reach the opposite wall, which is also designed as a guide surface 223, in order to then reach the outlet section 224.
- the distances traveled by the different fibers of the fleece V distributed over the fiber width from the entry section 222 to the exit section 224 are preferably of the same length.
- the funnel-shaped fleece guiding device 220 can be slit open at one location on the longitudinal side in order to enable simple threading of a fleece end. It must be ensured that the fleece is not in it during operation
- Another alternative to helping threading is that a wall section of the fleece guiding device 220 can be folded away or removed.
- the fifth embodiment of the fleece guiding device 320 according to FIGS. 11 and 12 is formed in two parts.
- the guide surface 333 deflecting the central fibers is part of a body 331 which projects into a funnel 321 and is advantageously adjustable in its position.
- the body is preferably designed to be pivotable, in this case about an axis 339 (see double arrow f 5 ).
- To thread a fleece end the body 331 is first pivoted outwards, the fleece end is pushed deep into the funnel 321 and the machine is started in slow speed. If the threading is successful, the body 331 can then be pivoted from the maintenance position into its operating position.
- the funnel 321 also has a guide surface 323 which guides the central fibers on their last path to the outlet section 324 after they have previously been deflected by the guide surface 333 from their direct path from the inlet section 322 to the outlet section 324.
- FIG. 12 shows the fleece guiding device 320 for better understanding in a top view.
- a fleece guiding device 420 is provided, which is designed similar to that according to FIGS. 1-5. However, the following differences exist:
- the entry section 422 determined thereby is bent in the form of a partial cylinder with a small radius, which merges into a guide surface 423 with a smaller curvature in the direction of the fleece. This curvature is made stronger towards the center of the fleece than at the edge in order to achieve the effect according to the invention.
- the outlet section 424 is essentially semicircular and therefore open, also in order to provide easy access to the subsequent elements.
- the lateral edge sections 427a run essentially linearly from the curved entry section 422 to the exit section 424.
- a flange 428 is provided on each of the two outer sides thereof, to each of which a swivel foot 429 is attached.
- the two swivel feet 428 are attached to a block 409 so as to be pivotable about an axis 411, so that funnel 421 can be brought from an operating position (FIG. 13) into a maintenance position (FIG. 14) for threading the free fleece end, see FIG. Arrows around the axis 411.
- the hopper 421 swivels from the operating position into its maintenance position, so that there is easy access to eliminate the fault.
- the lower edge 427a of the funnel 421 lies on the block 409 and partially encloses a crater-like opening 430, into which a funnel insert (not shown) and then a belt funnel can be inserted in the nonwoven direction.
- the difference in the pivotability compared to the embodiment according to FIGS. 1-5 is that only the funnel 421 is pivoted and not the subsequent elements (e.g. fleece nozzle insert, belt funnel).
- the embodiments shown in the figures have in common that the fibers of the fleece V are each guided without abrupt deflections and thus to the respective outlet section in a gentle manner. This also applies to the impact of the fibers on the guide surfaces in the entry section of the respective fleece guide device; the fibers preferably meet the guide surface almost tangentially or at a very small angle.
- the respective entry sections, guide surfaces and exit sections are each formed in one piece.
- the guide surface forms a single element for itself and can be introduced into the space between the inlet and outlet sections, either fastened there or arranged movably, for example with the aid of a swivel mechanism.
