Definitions

  • the invention relates to a method and a device for producing wet-laid nonwoven fabrics according to the preamble of claims 1 and 8, respectively.
  • WO 2015/000687 A1 discloses a method and a device, wherein the fleece is removed from the sieve via a closed removal.
  • Another approach is to avoid free trains by compromising the arrangement of the machine components, e.g. on top of each other.
  • water is used to shape fibers into a flat structure or wet web.
  • the fibers in the water are passed over a sieve. While the water is sucked through the sieve, the fibers are deposited on the sieve. This process stage is called sheet formation.
  • the nonwoven still contains significantly more water than fibers after sheet formation. Vacuum suction cups continue to remove water from the nonwoven fabric, but the fabric is at the interface after the sieve that is usually formed by an inclined wire former, not a stable product, but a loose composite of fibers.
  • the subject matter of the present invention is based on the object of creating a method and a device for the production of wet webs which improve the web threading at the start of production and / or after a production interruption.
  • the required treatment units / machine components can be arranged one after the other in a known manner. Free trains are provided between the screening device and the at least one subsequent treatment unit. This is particularly advantageous when all treatment units / machine components are to be equipped with different sieve belts for an economical and energetically optimized mode of operation. This is particularly the case, for example, when the production of a wet-laid nonwoven fabric comprises an inclined wire former, a hydroentanglement device and a dewatering belt. Which Interfaces resulting between these treatment units should as far as possible not affect one another, so that free trains are advantageous in this respect.
  • the temporarily closed trains offer the possibility on the one hand to allow free trains between the treatment units / machine components and on the other hand to assign the temporarily closed trains to an automated solution so that the nonwoven web can be performed at higher machine speeds.
  • the wet nonwovens produced on a sieve device especially when long fibers are used, have sufficient strength to be detached from the sieve of the sieve device with compressed air.
  • a web threading device to be provided at the interfaces between the screening device and a subsequent treatment unit or at interfaces between two adjacent treatment units, which is designed as a temporarily closed train.
  • a tail threading belt of the nonwoven web which is cut from the running web on the outlet side of a sieve belt of the sieving device, is gripped by the temporarily closed draw.
  • This strip is transferred to the subsequent treatment unit with air currents from the temporarily closed train.
  • the cut tail threading belt is removed from the sieve in order to be transferred to a transport device, for example by compressed air.
  • This band can be caught by the subsequent treatment unit using an air flow, so that the created transfer of the tail threading band represents a controlled, temporarily closed train.
  • the invention relates to a method and an apparatus for producing wet laid nonwovens.
  • a wet-laid non-woven system 1 provided for this purpose is shown in FIG Fig. 1a and Figure 1b shown.
  • a fiber suspension device 2 a sieve device 3 at least one subsequent treatment unit 4 and, if necessary, a winder 5 are arranged in series Fig. 1a and Figure 1b
  • a hydroentanglement device is provided as at least one treatment unit 4.
  • Further treatment units 6, 7 are also provided.
  • the treatment unit 6 is, for example, a drying screen and the treatment unit 7 is, for example, a dryer.
  • the screening device 3 is shown as an inclined screen former.
  • An interface 8 is provided between the sieve device 3 and the subsequent treatment unit 4.
  • an interface 9 is provided between the treatment unit 4 and the treatment unit 6. Both interfaces 8, 9 are designed as free trains when the nonwoven web 10 is listed.
  • the nonwoven web 10 When production starts or after a production interruption, the nonwoven web 10 needs to be fed in order to overcome the distance in the area of the interfaces 8, 9.
  • the method according to the invention for the production of wet-laid nonwovens provides that an aqueous suspension with fibers is deposited on a sieve 11 of the sieving device 3 and drained through suction boxes 12 under the sieve is used for sheet formation of a nonwoven web 10, which is removed from the screen 11 and fed to at least one subsequent treatment unit 4 before the nonwoven web 10 can finally be wound onto a roll 23.
  • the nonwoven web is transferred from the wire 11 to the at least one subsequent treatment unit 4 and / or at an interface 9 between two treatment units 4, 6 when production starts and / or after a production interruption with the aid of a web guide 13.
  • the web threading 13 takes place via a respectively temporarily closed draw of a free draw between wire 11 and the at least one subsequent treatment unit 4 and / or a free draw at an interface 9 between treatment units 4, 6.
  • the respectively temporarily closed draw of a web threading 13 is generated via air currents. These air currents act on a tail threading belt 14, which is cut by means of a cutting device 16 which acts on the nonwoven web 10 on the outlet side of the wire 11.
  • the end threading tape 14 is separated from the remaining web 15 of the nonwoven web 10 by means of the cutting device 16.
  • the web threading takes place by means of the tail threading belt 14, while the remaining web 15 falls into a pulper 17.
  • Fig. 3a shows, according to the invention, the tail threading belt 14 as part of the running nonwoven web 10 is lifted off the wire 11 by blowing it with a compressed air device 18.
  • the tail threading tape 14 is attached to a transport path formed by the transport path device 19 and is taken up by suction on the respective subsequent treatment unit 4.
  • the suction at the subsequent treatment unit 4 takes place, for example, by means of a suction catch device 21.
  • wet nonwoven products have sufficient strength when they have been dewatered on a sieve device 3, which is designed, for example, as an inclined sieve machine. This also applies in particular when long fibers are used to produce the nonwoven web. Because of this strength of the nonwoven web produced by the sieve device 3, the sieve web can be detached from the sieve 11 with compressed air from the compressed air device 18 for a web threading.
  • the tail threading belt 14 lifted off the screen 11 has sufficient stability to be transferred to the transport path device 19 by compressed air.
  • the transport path device 19 is in Fig. 2 shown as an air baffle device. In Fig. 3 the transport path device 19 is designed as a suction conveyor belt. Both transport path devices 19 of the Fig. 2 and the Fig. 3 form a negative pressure due to the air currents present on, preferably on the underside of the transport path device 19. This makes it possible for the tail threading belt 14, lifted off by the compressed air of the compressed air device 18, to be moved to the downstream treatment unit 4.
  • the transfer of the tail threading tape 14 created in this way represents a temporarily closed train. It is essential to the extent that the construction according to the invention enables controlled lifting, transfer and the then subsequent controlled pick-up.
  • the treatment unit 4 is, for example, a hydroentanglement.
  • the tail thread 14 can be further stabilized by such hydroentanglement.
  • the transfer of the end threading belt can again be carried out with compressed air from the sieve belt 20 of the Treatment unit 4 are lifted off and transferred with a vacuum-generating transport device 19 to a next screen belt 22 of a subsequent treatment unit 6 according to the same principle.
  • this further treatment unit 6 is, for example, a vacuum drainage.
  • the end threading belt 14 is usually sufficiently stable to be inserted into a rope cutter.
  • the lifting can in turn take place with compressed air through the sieve belt.
  • the end threading belt 14 can be caught by an air baffle or another sieve belt and transferred to a rope cutter.
  • the described transfer of the tail threading belt 14 with the temporarily closed train can be carried out without problems at production speeds between 200 to 250 m / min and higher.
  • the nonwoven web 10 can be spread across the entire width of the fabric on the screen device 3.
  • the wet fleece is sufficiently stable to be guided over the entire width of the fabric directly after the screening device 3 via a free pull to the next treatment unit.
  • a variable vacuum suction box 26 which can be displaced along the sieve belt 11 is preferably mounted under the sieve belt 11 of the sieve device 3. After the fleece web runs in full width on the production line, this vacuum suction box 26 can be used to precisely define the position of the web lift-off by adjusting the vacuum suction box 26 on the one hand and the setting of the vacuum on the other. So that the free train between the vacuum suction box 26 of the sieve device 3 and the suction catch device 21 of the subsequent treatment unit 4 are precisely defined. Uneven lifting of the web is prevented.
  • the web tension between the two wire belts 11, 20 is preferably controlled with a slack control. The same statements apply to the interface 9 between two treatment units 4, 6.
  • FIG. 3b shows, according to the invention, the tail threading belt 14 is removed from the wire 11 as part of the running nonwoven web 10 by suction by means of a removal suction device 30 with a suction element 31.
  • a suction roller is arranged as a removal sucker 30, which can act on a screen 11 in such a way as to suck the end threading belt 14 directly from the screen 11 by means of negative pressure.
  • Fig. 3a statements made accordingly.
  • the tail threading tape 14 is then passed on, as described above Fig. 3a was carried out in detail.
  • the nozzle 18, according to Fig. 3a is provided, is then preferably omitted.
  • the nonwoven web can be transferred more economically than conventional solutions, and the controlled free draw also offers an economically favorable solution for guiding the web.
  • the aforementioned slack regulation can be supplemented by a control device for controlling the lifting, transferring and receiving of a tail threading tape 14 at the interfaces 8, 9 with a web threading 13.
