Definitions

  • the invention relates to a device for bringing together a textile nonwoven fabric that can be removed from a card or card holder to form a fiber sliver and for introducing the same into a conveyor for storage or further processing, with an approximate take-off point that is formed, in particular, by a take-off roller whose width adjoining trough with a bottom and with, preferably funnel-like, side walls, and with a funnel arranged at the end of the trough.
  • a device of the type mentioned is known from DE-AS-12 32 504.
  • the funnel-shaped trough already enables the pieces of nonwoven to be connected again in the event of a nonwoven break. Nevertheless, the carding fleece must first be inserted by hand.
  • the funnel is designed as an injector to be operated with compressed air for the continuation and shaping of the sliver and the end of the tub is connected to a suction device sucking the nonwoven fabric to the injector.
  • the automatic removal of the nonwoven fabric from a card and the subsequent merging to form a sliver as well as the automatic insertion of the same into a conveyor is possible in a simple manner.
  • the fiber fleece arriving, for example, from the removal roller of a customer of a card or a card runs onto the tub floor in its full width.
  • The, preferably funnel-shaped, side walls fold the lateral areas of the nonwoven fabric toward the longitudinal center of the trough, so that the nonwoven fabric is pre-compressed. Due to the suction device arranged at the end of the tub, the nonwoven fabric is automatically sucked to the injector, into which it enters as a voluminous fiber strand.
  • the fiber strand is further tapered in the injector and fed into the conveyor or subsequent components.
  • the advantage of the device according to the invention lies not only in the fact that the nonwoven does not have to be inserted by hand even when the card or card and the device are started up, but also in the fact that the nonwoven is continuously formed into a sliver without progress There are discontinuities in the device that could lead to a fleece break.
  • a fleece blowing device which extends substantially over its entire width, is arranged on the removal roller, the blowing direction of which points approximately tangentially to the lateral surface of the removal roller to the bottom of the tub.
  • This fleece blowing device has a triple function. On the one hand, it advantageously supports the detachment of the nonwoven fabric from the take-off roller of a card, on the other hand, the nonwoven is pre-cleaned by blowing with air. The air emerging from the blowing device flows with the nonwoven fabric into the funnel-shaped trough, so that the transport effect of the suction device at the tapering end of the trough is supported.
  • the end of the trough bottom facing the removal roller is arranged below the removal roller and if the fleece blowing device is approximately diametrically opposite the consumer. This increases both the cleaning effect and the conveying effect of the fleece blowing device. The blown-out foreign objects thus get onto the tub floor and are discharged along the same.
  • the bottom of the trough preferably has a curvature which extends uniformly over the entire width of the bottom of the trough and is convex to the transport path of the fleece.
  • This curvature promotes the even folding of the nonwoven fabric into the sliver.
  • the curvature also supports a safe insertion of the fiber sliver or the fiber strand into the injector, which already lifts the fiber fleece over the rest of the bottom of the tub.
  • the curvature creates a kind of wing effect, which leads to an acceleration of the sucked-in air and thereby has a favorable influence on the merging of the nonwoven fabric into a sliver.
  • the curvature viewed in the direction of transport of the nonwoven fabric, has an increasing ramp, an adjoining, approximately horizontal threshold and a ramp falling towards the end of the trough.
  • This configuration of the curvature preserves the wing effect, but the threshold ensures that the tapered nonwoven fabric is guided correctly to the inlet opening of the injector.
  • the angle of inclination, measured relative to the horizontal, of the descending ramp is greater than that of the ascending ramp.
  • the height of the side walls increase towards the end of the tub. This is particularly advantageous if a loose nonwoven fabric is processed, which becomes thicker when the tub is tapered to the side.
  • a further development of the invention provides that the side walls on their upper edges approximately horizontal, to the longitudinal have deflecting surfaces pointing in the middle of the tub. These deflecting surfaces cause the lateral edges of the nonwoven to curl, which is particularly advantageous when the device starts up, since the nonwoven is folded into a loose fiber strand without great friction.
  • this is arranged in a housing connected to the suction device, which adjoins the end of the tub, with a into the tub between the housing and the injector opening annular gap is formed. Via this annular gap, a gas flow is generated in the trough, which surrounds the fiber fleece and the fiber strand that has been merged therefrom on the long sides and thereby holds them together. Since the inlet opening of the injector is located in the center of this flow, the fiber strand preformed in the tub is automatically presented to the injector without any manual corrections being required. The air flow surrounding the fiber strand also causes impurities in the nonwoven fabric, e.g.
  • Short fibers, dust, etc. are sucked out of the fiber strand and can be fed to a filter system via the suction device. In this way, in addition to cleaning the nonwoven fabric, it is possible to ensure that as few impurities as possible from the nonwoven fabric get into the environment.
  • the injector has a transport channel that tapers in the direction of the conveyor and a mouthpiece channel that adjoins the transport channel in the transport direction and tapers in the direction of the conveyor, one directed towards the conveyor between the transport channel and the mouthpiece channel
  • Annular gap nozzle generating gas flow is arranged.
  • a swirl device is advantageously assigned to the annular gap nozzle. This swirl device generates a swirl in the air flow leaving the annular gap nozzle, which swirl stabilizes the air flow and gives the sliver a rotation.
  • the swirl device can be implemented in a particularly simple manner by means of swirl grooves provided in the annular gap nozzle.
  • the injector In order to achieve a particularly high degree of reliability when merging the nonwoven fabric and introducing it into the conveyor, particularly when the machine starts up, it is advantageous for the injector to be followed by a second injector in the direction of the conveyor.
  • This injector can be designed similarly to the first injector, but the diameters of the transport channel and the outlet channel will be designed correspondingly smaller.
  • the transport channel of the second injector leaving an annular gap free, adjoins the mouth channel of the first injector concentrically.
  • the conveying air fed in through the annular gap nozzle of the first injector can escape through the gap, thereby ensuring pressure equalization between the two injectors.
  • annular gap is connected to the suction device. This ensures a particularly rapid reduction in pressure between the injectors, with residual dust particles also being sucked out of the fiber sliver.
  • a pair of calender rollers is arranged downstream of the outlet channel of the second injector in the transport direction. This pair of calender rolls further compresses the sliver, which has already been folded closely together by the second injector.
  • a fleece suction device is arranged above the trough.
  • the card from which the nonwoven is to be removed starts up, there is initially no closed nonwoven, but rather individual pieces of nonwoven. These individual pieces of fleece are initially not yet suitable for forming a continuous sliver.
  • the fleece suction device With the fleece suction device, these individual fiber and fleece pieces can therefore be suctioned off when the device starts up until a closed fleece reaches the tub. Then the fleece suction device can either be switched off completely or the suction power can be throttled, so that dust particles and short fibers can be sucked out of the fleece with this fleece suction device.
  • the fleece suction device is arranged at the end of the tub in front of the first injector, it can be made relatively small and still ensure that all non-contiguous pieces of fiber and fleece are sucked off when the device starts up.
  • the fleece suction device and the suction device for the housing are connected to a vacuum source via control valves.
  • blow-off device and the annular gap nozzles of the injectors are connected to a pressure source via control valves.
  • the shuttle valve can be switched in the start-up phase of the device when non-contiguous pieces of fleece get into the tub so that these fleece pieces are sucked off by the fleece suction device. After the start-up phase, the shuttle valve can then be flipped so that the fleece suction device is out of operation, while the suction device of the housing is then connected to the vacuum source, so that the continuous fleece can be sucked into the injector.
  • 1 is a device 1 for automatically merging one with one Removal roller 2 shown by a customer 3 of a card or a card removable textile fiber fleece 4 to a sliver 5.
  • the device 1 is followed by a delivery pipe 7 connected to a vacuum source 6.
  • the conveyor tube 7 can lead to a can in which the sliver 5 is deposited, or to a pre-spinning or spinning station.
  • a trough 8 with a bottom 9 and with funnel-like side walls 10 adjoins the take-off roller 2.
  • an injector 11 to be operated with compressed air is arranged for introducing the sliver into subsequent components to be described further below.
  • the end of the tub 8 facing the take-off roller 2 is adapted approximately to the width of the take-off roller 2. From there, the tub 8 tapers in the direction of the inlet opening of the injector 11. It is pointed out at this point that FIG. 3 is only a schematic illustration. The scale ratios are not reproduced true to nature. For the sake of simplicity, the take-off roller is shown narrower than it would correspond to its actual width.
  • a fleece blow-off device 12 is arranged on the take-off roll 2 and extends essentially over its entire width, the blow direction B of which points approximately tangentially to the lateral surface of the take-off roll at the bottom 9 of the tub 8.
  • the fleece blowing device 12 is optionally via a control valve 13 with a slightly overpressure, e.g. 10 mm WS, standing source 14 connected.
  • the air flow emerging from the fleece blowing device 12 is generated by a gap nozzle 15 which extends approximately over the entire width of the take-off roller 2.
  • the bottom 8 of the tub 9 is arched, the curvature 16 extending uniformly over the entire width of the bottom 9.
  • the curvature 16 has a profile approximated to an airfoil, which extends in the transport direction T. If one looks more closely at the curvature 16 of the trough base 9, it can be seen that the curvature 16, seen in the transport direction T of the nonwoven fabric 4, first has a flat rising ramp 17, an adjoining, approximately horizontally oriented threshold 18 and one towards the tapered end 19 descending ramp 20.
  • the inclination angle ⁇ of the descending ramp 20, measured in relation to the horizontal, is greater than the inclination angle ⁇ of the ascending ramp 17.
  • the side walls 10 have at their upper edges approximately horizontal deflecting surfaces 22 pointing towards the longitudinal center 21 of the tub 8.
  • the entire trough 8, that is to say the bottom 9, the side walls 10 and the deflection surfaces 22, can be produced from a sheet metal.
  • FIG. 2 it can be seen that the tapering end 19 of the tub 8 is connected to a suction device 23 which transports the nonwoven fabric 4 or the already loosely folded fiber strand into the injector 11.
  • the suction device 23 comprises a housing 24 which adjoins the tapered end 19.
  • the injector 11 is arranged such that an annular gap 25 opening into the trough 8 is formed between the opening of the housing 24 facing the tapered end 19 of the trough 8 and the outer circumference of the injector 11.
  • the housing 24 is connected to a vacuum source 27 via a suction line 28 and via a control valve 26.
  • the suction direction in the area of the annular gap 25 is indicated by the arrows A.
  • the injector 11 itself has a transport channel 29 which adjoins the tapered end 19 of the trough 8 and tapers in the transport direction T.
  • the transport channel is adjoined by a mouthpiece channel 30, which also tapers in the transport direction.
  • An annular gap nozzle 31 is arranged between the transport channel 29 and the mouthpiece channel 30, the outflow direction of which points in the transport direction T.
  • the annular gap nozzle 31 is arranged on the inner circumference of the injector 11 and therefore generates a concentric flow.
  • swirl grooves which are not apparent from the drawing, are provided, which force a swirl movement on the flow.
  • the annular gap nozzle 31 is connected to a compressed air source 34 via a compressed air line 32 and a control valve 33.
  • a further injector 36 adjoins the mouth 35 of the mouthpiece channel 30 in the transport direction T.
  • this second injector 36 is similar to that of the first injector 11. It also comprises a conically tapering transport channel 37, an annular gap nozzle 38 and a mouthpiece channel 39 adjoining the annular gap nozzle 38.
  • the annular gap nozzle 38 is also via a compressed air line 40 and a control valve 41 is connected to a compressed air source 42.
  • the annular gap nozzle 38 has swirl grooves, not shown in FIG. 2, which produce a swirl in the nozzle flow.
  • the mouth 43 of the second injector 36 differs from the mouth 35 of the first injector.
  • a pair of calender rollers 44 adjoins the mouth 43 of the second injector and forms a conveyor gap 45.
  • the sliver 5 leaving the mouth 43 is introduced into the conveying gap 45 by the second injector 36.
  • the conveyor gap 45 therefore causes compression of the sliver in its vertical extent.
  • the mouth 43 of the injector 36 is therefore designed such that it has a vertical longitudinal gap 46 which is oriented transversely to the substantially horizontal conveyor gap 45 of the pair of calender rollers 44.
  • the vertical longitudinal gap 46 of the mouth 43 is designed to be open radially to the outside.
  • the contour of the mouth 43 is adapted in the region of the longitudinal gap 46 to the outer contour of the pair of calender rollers 44.
  • annular gap 47 is left free between the mouth 35 of the first injector 11 and the entry into the transport channel 37 of the second injector 36.
  • the transport channel 37 of the second injector 36 which is concentric to the mouth 35, is also arranged inside the housing 24, as can also be seen from FIG. 2. This means that the suction device 23 is also effective on the annular gap 47.
  • the conveying air introduced by the first injector 11 can escape at the annular gap 47, which contributes to the rapid pressure reduction in the injectors 11 and 36.
  • a fleece suction device 48 is arranged above the tub 8, at the tapered end 19 thereof, directly in front of the injector 11.
  • the fleece suction device 48 comprises a suction opening 49, which lies approximately at the level of the upper edge of the side walls 10.
  • a suction line 50 connects to the suction opening 49 and is connected to a vacuum source 52 via a control valve 51.
  • the nonwoven suction device 48 is switched on in this operating state of the device 1.
  • the fleece suction device 48 sucks air through the funnel-shaped trough 8 via the suction opening 49 and thereby generates a conveying flow for the individual pieces of fleece.
  • the nonwoven pieces are thus conveyed through the trough 8 and lift off approximately at the level of the threshold 18 and are conveyed by the suction device 48 through the suction opening 49.
  • the individual pieces of fleece sucked off in this way can be separated on a separator (not shown in more detail).
  • the take-off roller 2 removes a continuous non-woven fabric 4 from the take-off 3 of the card.
  • This continuous fiber fleece 4 is also blown through the fleece blowing device 12 onto the bottom 9 of the tub 8.
  • This fiber fleece 4 is already suitable for producing a fiber sliver.
  • the control valve 51 of the fleece suction device 48 is therefore switched off, or at least throttled to such an extent that the fleece 4 is no longer suctioned through the suction opening 49.
  • the control valve 26 of the suction device 23, which was already open from the beginning, is now opened further, so that a more intensive drag flow is created by the annular gap 25 at the tapered end 19 of the tub 8, which flows the nonwoven fabric 4 through the tub 8 to the injector 11 brought up.
  • the obliquely tapering side walls 10 and their deflecting surfaces 22 cause the nonwoven fabric 4 to be brought together and preformed into an even more loose fiber strand.
  • the curvature 16 located on the bottom 9 of the tub 8 is of particular importance here.
  • a wing effect on the one hand reduces friction between the nonwoven fabric and the tub base 9, and on the other hand, a vertically oriented suction flow is generated on the descending ramp 20, i.e. behind the threshold 18, which supports the lateral merging of the nonwoven fabric 4 into a fiber strand.
  • a round i.e. in the horizontal dimension narrower and therefore in the vertical dimension higher, fiber strand can be produced.
  • This fiber strand is drawn into the transport channel 29 of the first injector 11 by the drag flow.
  • the control valve 33 of the first injector 11 is opened in this start-up phase, so that compressed air is introduced into the injector 11 via the compressed air line 32 and the annular gap nozzle 31.
  • the flow generated in this way further promotes the fiber strand, the fiber strand through the tapering in the transport channel and the Mund Serialska nal is further compressed.
  • a pre-rotation takes place through the swirl flow.
  • the fiber strand can now already be referred to as sliver 5.
  • the injector 11 introduces the sliver 5 thus formed into the second injector 36, the control valve 41 of which is also open in the start-up phase, so that compressed air with swirl can pass into the second injector 36 via the compressed air line 40 and the annular gap nozzle 38.
  • a tip is generated on the sliver, which is injected by the flow into the conveying gap between the pair of calender rolls, from where the sliver 5 goes directly into the conveying tube 7.
  • the sliver 5 can, for example, be deposited in a spinning can or otherwise processed.
  • the two compressed air sources of injectors 11 and 36 are switched off, while vacuum source 27 continues to suck. From then on, the passage of the fiber sliver 5 takes place purely mechanically from the injector 11.
  • the start-up phase ends when a sensor, not shown, arranged in the start region of the conveying tube 7 detects the start of the sliver and emits a signal to shut off the compressed air supply to the injectors 11 and 36.
  • the blowing and suction devices are of further importance during normal operation of the device.
  • the fleece blow-off device 12 thus already blows contaminants, such as dust, short fibers and small foreign bodies, out of the incoming fiber fleece 4.
  • These small impurities pass through the annular gap 25 into the housing 24 of the suction device 23 and can be separated on a separator, not shown. Finally, further dirt can be sucked out of the annular gap 47 between the first injector 11 and the second injector 36.
  • the vertical longitudinal gap 46 in the mouth 43 of the second injector 36 causes the fiber sliver to be compressed laterally in particular. This means that the sliver 5 leaving the mouth 43 has a greater extent in the vertical direction than in the horizontal direction.
  • the sliver 5 thus shot into the conveyor nip of the pair of calender rollers 44 is then also compressed in its vertical extent by the pair of calender rollers. In this way, the sliver 5 runs through the conveyor tube 7.
  • the tub is closed at the top, for example by a fixed or detachably attached lid.
  • the fleece suction device 48 and the first injector 11 can be mounted so that they can be opened laterally for control purposes.
  • tub is to be understood to mean that it is a component which has a base which supports the fleece and elements which bring the fleece together from the side. These elements can also be formed by wall sections running essentially parallel to the customer axis, in which case the suction effect of the injector 11, possibly supported by lateral injection nozzles, ensures that the fleece is brought together. In so far the protection should not be limited to the specific tub described above.
  • the removal roller 2 may also be omitted and the fleece can be removed directly from the consumer 3 by means of the blowing device B or the like.
