Definitions

  • the invention relates to a method for depositing a textile sliver into a can, in which the sliver is drawn into a deposit tube by means of a compressed or suction air flow in a pull-in phase and then continuously transported through the deposit tube into the can in a deposit phase.
  • the invention also relates to a device for carrying out the method, with a turntable, to which a deposit tube is assigned, at the discharge end of which a pair of pressure rollers is arranged, and with a compressed gas injector for drawing in the sliver.
  • nonwovens removed from a card have been formed into a fiber band
  • these fiber bands are generally deposited in so-called spinning cans before further processing.
  • Such a device is known from US-PS 4318206 (CH-PS 639628).
  • the turntable of the known device is shielded by a fixed hood, the space under the hood being connected to a suction line.
  • the delivery tube protrudes with the delivery end through the plane of the turntable into the spinning can, the pair of pressure rollers being arranged on the underside of the turntable.
  • the discharge end, which is relatively close to the pair of pressure rollers is provided with outlet openings which open into the space enclosed by the cover and the turntable. Due to the negative pressure generated in the enclosed space by means of the suction line, the sliver is drawn in through the laying tube up to the pressure rollers.
  • a compressed gas injector can also be provided.
  • the invention is therefore based on the object of improving a method and an associated device of the type mentioned at the outset so that, with improved drawing-in properties, effective dedusting of the sliver can also be carried out in the laying phase of the sliver.
  • This object is achieved in that a suction air flow is generated in the laying tube during the laying phase, which is directed against the transport direction of the sliver.
  • this suction air flow is not generated for transport purposes, but only for the ventilation and removal of dust particles and short fibers. In this way, the air flow used to insert the sliver into the laydown tube cannot be impaired by short fibers or dust particles.
  • the suction air flow can also be maintained at full strength in the laying phase, since no outward air flow is generated at the conveying gap between the pressure rollers.
  • the object is achieved according to the invention by a suction connection which can be connected to a vacuum device and which, viewed in the transport direction, is at a distance from the end of delivery Storage tube is arranged.
  • a suction connection which can be connected to a vacuum device and which, viewed in the transport direction, is at a distance from the end of delivery Storage tube is arranged.
  • a first compressed gas injector is arranged directly in front of the pair of pressure rollers and behind the discharge end of the delivery tube and a second pressure gas injector, viewed in the transport direction, at a distance before the delivery end of the delivery tube, with a gap between the delivery end of the delivery tube and the input of the first pressure gas injector is trained.
  • the gap brings about a pressure equalization when the fiber sliver is drawn in, so that no conveying air can flow into the inlet of the first compressed gas injector from the laying tube.
  • a larger pressure difference can be built up in the first pressurized gas injector, which enables the sliver to be drawn into the conveying gap between the two press rollers even more reliably.
  • air for the suction air flow can enter the laying pipe through the gap in the laying phase.
  • a compressed air connection line is passed through the first rotary coupling, for the first compressed gas injector arranged at the discharge end of the storage tube.
  • the storage tube with the associated compressed air connection line of the first Turn the compressed gas injector around the rotary coupling without having to turn the part of the compressed air connection line that leads to the first rotary coupling from the outside.
  • the rotary coupling has two rotating parts which can be rotated relative to one another and which enclose a compressed air space which is sealed off from the outside and to the storage tube, a connection bore opening into the compressed air space being provided on both rotating parts for a compressed air line.
  • the rotating parts of the rotary coupling are designed as sleeves which are essentially coaxially one inside the other and are connected to the respective tube and can be rotated relative to one another by means of two radial bearings which are spaced axially from one another and sealed, the compressed air space being delimited by the radial bearings and the sleeves, and wherein the connection bore in the outer sleeve is designed as a radial bore, while the connection bore in the inner sleeve is essentially designed as an axial bore.
  • the turntable for depositing the sliver in the can is not only rotated about an axis that passes through the center of the turntable, but is stored in a lid, which in turn rotates about an axis, which is arranged eccentrically to the center of the turntable.
  • the can can rotate around the latter axis instead.
  • the suction connection is arranged in the region of the second rotary coupling.
  • the suction connection is in this way close enough to the discharge end of the storage tube and can nevertheless be provided at the non-rotating end of the transport tube.
  • the suction air flow In the conveying direction upwards from the second rotary coupling, the suction air flow always acts in the transport direction of the sliver; only between this rotary coupling and the outlet of the deposit tube does the suction air flow towards the sliver.
  • the suction connection is formed on a part of the second rotary coupling which is connected to the transport pipe.
  • suction connection is designed as a flange attached to the second rotary coupling, to which the transport pipe and a suction line are connected are.
  • a particularly uniform suction of the short fibers and dust particles is made possible by the fact that between the end of the transport pipe opening into the rotating coupling and the second rotating coupling a gap is formed which is sealed to the outside by the flange and which is connected to the suction line by flow.
  • a gap is formed which is sealed to the outside by the flange and which is connected to the suction line by flow.
  • FIG. 1 shows, in a partially cut and partially broken away side view, a device 1 according to the invention for depositing a textile sliver into a can 2.
  • a turntable 3 is arranged, to which a storage tube 4 is assigned.
  • the deposit tube 4 is designed to be rotatable and, on the one hand, is held with its upper end in a first rotary coupling 5, while the lower, discharge end 7 faces a rotatable disk 6.
  • the rotatable disc 6 is mounted within a larger rotatable disc 8, which in turn is rotatably supported in an outer edge 9.
  • both the small rotatable disk 6 and the large rotatable disk 8 are each arranged to be rotatable about their own center.
  • the sliver leaving the discharge end 7 is deposited in an exploded, helical pattern.
  • the deposit tube 4 has at its discharge end 7 a pair of pressure rollers 10, from where the sliver passes through a small rotating disc 6 into the interior of the can 2 through a mouthpiece tube 11 adapted to the contour of the pair of pressure rollers 10.
  • laying tube 4 is shown in two positions (in a solid line and in a broken line).
  • first rotary coupling 5 Arranged above the first rotary coupling 5 is an essentially S-shaped pipe bend 13 which can be rotated relative to the support tube 4. The upper end of the pipe bend 13 is connected to a transport pipe 15 via a second rotary coupling 14.
  • the transport tube 15 can for example lead from a card, not shown here.
  • the pipe elbows 13 rotate about the axis 16 of the can and on the other hand the deposit tube 4 about the axis 17 of the small rotatable disc 6 and also about the axis 16.
  • the axes of the two Swivel couplings 5 and 14 coincide with axes 17 and 16, respectively.
  • a first pressurized gas injector 18 is connected between the discharge end 7 and the pair of pressure rollers 10, which introduces the sliver into the conveyor nip between the two pressure rollers 10.
  • the first pressurized gas injector 18 is designed to converge in the interior and ends in a longitudinal gap 37, which is arranged transversely to the delivery gap between the two pressure rollers 10.
  • the compressed air is fed through an annular gap nozzle (see also compressed gas injector 20).
  • a gap 19 is formed between the first compressed gas injector 18 and the discharge end 7 of the deposit tube 4, through which gap air can enter or exit.
  • a second compressed gas injector 20 is arranged at a distance from the discharge end 7 of the deposit tube 4. More specifically, the second compressed gas injector 20, as seen in the transport direction, is arranged in front of the second rotary coupling 14 in the transport pipe 15.
  • the compressed gas injector 20 is designed as an annular nozzle and, together with the first compressed gas injector 18, is connected to a common compressed air source 21.
  • a first connecting line 22 leads from the compressed air source 21 to the first compressed gas injector 18 and a second connecting line 23 leads to the second compressed gas injector 20. While the second connecting line 23 leads directly to the second compressed gas injector, which is arranged in a stationary manner with the transport pipe 15, the first connecting line leads via the second rotary coupling 14 and via the first rotary coupling 5 to the first compressed gas injector 18.
  • the two rotary couplings 5 and 14 are constructed essentially identically and each have two rotating parts 24 and 25 which can be rotated relative to one another.
  • the two rotating parts 24 and 25 enclose a compressed air space 26, on both Rotary parts 24 and 25 each have a connection bore 27 and 28 opening into the compressed air space 26.
  • the two rotating parts 24 and 25 are designed as sleeves which are essentially coaxially one inside the other and connected to the respective tube.
  • the outer sleeve 24 can be rotated relative to the inner sleeve 25 by means of two axially spaced deep groove ball bearings 29 and 30.
  • the grooved ball bearings 29 and 30, as can be seen in particular in FIG. 5, are sealed off from the compressed air space 26 with seals 31.
  • the compressed air chamber 26 is therefore limited by the outer sleeve 24, the inner sleeve 25 and the deep groove ball bearings 29 and 30 or their seals 31.
  • the connection bore 27 in the outer sleeve 24 is designed as a radial bore, while the connection bore 28 in the inner sleeve is essentially designed as an axial bore, wherein it can be seen in the drawing that the connection of the first connection line 22 to the axial bore 28 also takes place radially .
  • a suction connection 32 is provided in the region of the second rotary coupling 14. More specifically, the suction connection is formed directly on the outer sleeve 24 of the second rotary coupling 14, which is fixedly connected to the transport pipe 15.
  • FIGS. 3 and 4 The more precise design of the suction connection 32 can be seen in FIGS. 3 and 4. It can be seen there that both the transport pipe 15 and a suction pipe 34 are connected to a flange 33 on the upper side of the second rotary coupling 14. Between the end of the transport tube 15 opening into the second rotary coupling 14 and the rotary coupling itself, a gap 35 is formed, which is sealed to the outside by the flange 33 and is flow-connected to the suction tube 34. For this purpose, the gap 35 also extends below the suction pipe 34. The gap 35 is with the inside of the pipe bend 13 flow-connected and sealed against the compressed air space 26 by the inner sleeve 25 of the rotary coupling 14.
  • the suction pipe 34 is arranged behind the transport pipe 15 in FIG. 1 and lies slightly above the transport pipe.
  • the two compressed gas injectors 18 and 20 are fed with compressed air by the compressed air source 21 and via the connecting lines 22 and 23.
  • the two disks 6 and 8 each rotate about their axes 17 and 16, which is why the support tube 4 and the elbow 13 also rotate about these axes.
  • the first compressed gas injector 18 can be supplied with compressed air in spite of this rotation, the first connecting line 22 leads through the rotary coupling 14 and 5, respectively.
  • the respective connecting bores 27 and 28 can rotate relative to one another without the connecting line 22 being twisted.
  • a compressed air flow is generated in the transport pipe 15, in the downstream pipe bend 13 and in the storage pipe 4.
  • a suction air flow directed in the transport direction T forms in front of the second compressed gas injector 20.
  • This suction air flow draws in the fiber sliver up to the second compressed gas injector 20, after which the fiber sliver insertion is gripped by the compressed air flow and is conveyed through the second swivel coupling 14, the elbow 13, the first swivel coupling 5 and the laying tube 4.
  • the compressed air in the storage tube 4 can escape through the gap 19, so that no excess pressure can build up at the input of the first compressed gas injector 18, which would reduce the effect of the first compressed gas injector.
  • the first compressed gas injector 18 draws in the incoming sliver end and conveys it into the conveying gap between the two pressure rollers 10 rotating in the direction of the arrow (see dashed line). From there, the sliver is conveyed further through the mouthpiece tube 11 through the smaller rotatable disc 6 into the can 2.
  • the pull-in phase has now ended.
  • the two compressed gas injectors 18 and 20 are switched off, while the suction pipe 34 remains connected to a vacuum device 36.
  • the suction flow is weaker than the pressure flow, so that the latter outweighs the former in the pull-in phase.
  • a suction flow is formed in the suction pipe 34, which continues via the suction connection 32 both into the transport pipe 15 and into the pipe elbow 13 and the storage pipe 4.
  • a suction flow is formed in the suction pipe 34, which continues via the suction connection 32 both into the transport pipe 15 and into the pipe elbow 13 and the storage pipe 4.
  • the direction of the suction flow is shown by the arrows S. It can be seen that, seen in the transport direction T, the suction direction S in front of the suction connection 32 is aligned with the transport direction T, while, seen in the transport direction T, the suction direction S is opposite to the transport direction T behind the suction connection 32.
  • the counter-air flow has the effect that practically no short fibers or dust particles can escape in the area of the discharge end 7, the pair of pressure rollers 10 and the mouthpiece tube 11. It is thus not only achieved that the fiber sliver is already deposited substantially free of short fibers and dust particles in the can 2, it is also avoided that short fibers or dust particles can get into the environment.
  • the vacuum device 36 can have a separator in the form of a filter.
  • the slivers are deposited in the can 2 in a pattern, as can be seen in FIG. 2.
  • the mouthpiece tube 11 is preferably made of a plastic and is arranged so close to the contour of the pair of pressure rollers 10 that the best possible seal between the pair of pressure rollers 10 and the mouthpiece tube 11 results.
