Definitions

  • the invention relates to a nonwoven card for producing aerodynamically formed nonwovens - with a fiber feeding device, - with a master cylinder rotating at high speed, - With an in the area of the fiber take-off zone essentially tangential to the master cylinder, which leads to an air-permeable fleece transport device and with a suction device arranged under the fleece transport device, the centrifugal force on the master cylinder throws the fibers in the fiber take-off zone into the air flow generated in the air shaft, which conveys the fibers to the fleece transport device and deposits them there in the form of a fleece, and a method for aerodynamically forming a nonwoven fabric by applying the fibers on a drum rotating at high speed, by spinning the dissolved fibers in the area of a fiber removal zone from the drum into an air stream, - By transporting the fibers in the air flow to an air-permeable fleece transport means and by separating the fibers from the air flow on the nonwoven transport means.
  • Such fleece cards for producing aerodynamically formed nonwovens are known, for example, from US Pat. No. 4,064,600, US Pat. No. 4,097,965, US Pat. No. 4,130,915 and EP-A-0 093 585.
  • the deflection of the air flow at the deflection flap leads in a direction that contains a component in the opposite direction to the direction of rotation of the master cylinder excessive turbulence in the transport air, which affects the uniformity of the nonwoven fabric deposited on the nonwoven transport device.
  • the US-PS 4 130 915 relates to an improvement of the fleece card described above, in which the air shaft is only led to the master cylinder, the air shaft being supplied with compressed air if necessary, while additionally a segment of the carding area with a pressure between 150 and 400 mm Ws at an air flow of 28 m3 / (min ⁇ m) is applied.
  • EP-A-0 093 585 describes a fleece card in which a turbulent air flow is generated in an air duct which is tangential to the master cylinder.
  • the air shaft which hardly narrows in cross section, has a sharp bend in the area of the fiber take-off zone, which increases the turbulence of the air flow.
  • the invention has for its object to provide a fleece card, in which the aerodynamic fleece formation to produce a high uniformity of the fleece is improved even at high production speeds and large machine widths.
  • the air duct in its upper section is designed as an air intake gap which is essentially nozzle-shaped in cross section.
  • the design of the air shaft in its upper section as a nozzle-shaped air intake gap causes the suctioned air flow is disturbed as little as possible. There is no abrupt change in the air flow direction, so that eddy formation and turbulent flow conditions in the air shaft are avoided.
  • the aerodynamic shape of the air intake gap cross-section enables laminar air flow without turbulence, even at high flow speeds, so that the largest possible volume of air flows around the individual fibers detaching from the master cylinder, without them flowing along the outflow path between the master cylinder and the fleece transport device due to the formation of vortexes with neighboring ones Can catch and agglomerate individual fibers.
  • the laminar air flow enables a high level of uniformity of the fleece tray, which is reflected, for example, in a pile image without cloudiness. In this way, a nonwoven can be produced, the longitudinal and transverse strength values of which are the same.
  • the wall of the air shaft opposite the master cylinder is an air baffle which forms a first throttle point upstream from the master cylinder T with an opposite wall section and a second throttle point in the region of the fiber take-off zone with the circumferential surface of the master cylinder.
  • the narrowing of the cross section of the air shaft in an area upstream of the master cylinder enables the fiber take-off zone to be in a stabilized negative pressure area in which the flow velocity is largely homogenized across the entire width of the machine.
  • the upstream throttling point leads to an automatic immediate pressure equalization over the entire width of the machine, so that after the throttling point there is a volume flow which is uniform over the width.
  • the air baffle can be continuously curved. In this way, there are no sudden pressure changes or changes in air speed in the air shaft.
  • the air baffle has a circular cylinder curvature, the radius of which essentially corresponds to the master cylinder radius or is greater than the master cylinder radius.
  • the air baffle With a substantially matching radius of curvature of the master cylinder and the air baffle, there is a symmetrical cross-sectional constriction at the second throttle point, so that a further homogenization of the air flow takes place at the fiber take-off zone.
  • This second homogenization of the air flow is particularly advantageous because the air flow that has been homogenized over the width of the machine after the first throttle point mixes again with the air flow that is also conveyed by the master cylinder.
  • the air baffle is adjustable in such a way that the gap width of the first and / or the second throttle point can be varied.
  • the gap widths of the two cross-sectional constrictions also are separately adjustable.
  • the pressure conditions in the area of the fiber take-off zone can ultimately also be influenced.
  • the flow velocity of the air in the area of the fiber removal zone can essentially correspond to the peripheral velocity of the master cylinder. In this way, the sucked-in air flow, the air flow rotating with the master cylinder and the fibers thrown off by the main drum have the same speed, which enables mixing without swirling.
  • the flow rate of the intake air is preferably lower than the peripheral speed of the drum.
  • a carding section with a plurality of carding rolls arranged one behind the other with associated worker rolls is arranged between the fiber feed device and the master cylinder.
  • the carding tract brings about a particularly good dissolution of the fibers, so that the carding elements on the master cylinder only have to take on the task of fine dissolution, which means that the dissolved fibers can be considerably evened out across the width of the machine.
  • a second fan is provided which blows in an additional air flow in the upper section of the air intake funnel. This increase in the dynamic pressure at a throttle point ensures faster compensation of pressure and flow differences across the entire width of the machine.
  • the second fan blows the additional air flow in front of the first throttle point of the air shaft.
  • the second fan thus causes an increase in the dynamic pressure upstream of the first throttle point.
  • An airflow compression profile can be arranged in the area of the first throttle point across the width of the entire air shaft.
  • the airflow compression profile increases the throttle resistance and thus has a similar effect to the back pressure increase in front of the throttle point.
  • the airflow compression profile can advantageously accommodate an ionizing rod that electrostatically discharges the airflow that is drawn in.
  • the drum 1 has a machine frame 1 which accommodates five carding rollers K1 to K5 arranged one behind the other in a carding section, to which six worker rollers W1 to W6 are assigned.
  • the spun material or template fleece is fed by means of the feed roller F 'with feed trough.
  • the one on the last carding drum K5 Fleece taken from the master cylinder or Tambour T.
  • the drum T is provided with two card cover segments, which preferably consist of Cardmaster segments C1 and C2.
  • the worker rolls each affect two carding rolls.
  • the worker roller W2 forms, together with the roller AL1, a worker turning device assigned to the carding roller K2.
  • the worker turning device can also be assigned to the carding roller K4.
  • the worker roll W5 is omitted, while the worker roll W4 is arranged between the carding rolls K2 and K3. From carding roller to carding roller, in the direction of the progressing work process, an increase in the roller speed in connection with a systematic grading of the garnish is provided, so that a high carding effect for progressive fiber insulation is achieved.
  • rollers of the carding section, the lower worker rollers W1, W3, W5 and the reel can be covered with trough plates 10.
  • the drum roll has a diameter of approx. 550 mm.
  • the carding roller K5 preferably has the same diameter at approximately half the speed of the drum, while the carding rollers K1 to K4 can have a smaller diameter.
  • the preferred peripheral speed of the drum is in the range between 2,800 and 3,300 m / min, which corresponds to a rotation speed of 1,600 to 1,900 revolutions per minute with a drum diameter of 550 mm.
  • the extremely finely pre-dissolved fleece taken over from the carding tract is again finely resolved with the help of the cardmaster plates down to the individual fiber and then thrown off behind the last cardmaster segment C2 due to the high centrifugal forces from the drum T into an air stream which, depending on the amount of fiber, has a flow rate between 20 and 40 m / sec.
  • the amount of air required for this is approx. 50 to 100 m3 / min per m machine width.
  • the air flow is generated in an aerodynamically designed air shaft 2, which is designed in such a way that in the fiber take-off zone 3 behind the last card master segment C2 there is an air flow without turbulence, which is associated with the air flow D entrained and thrown by the drum and with the air flow thrown out by the drum Can mix fibers without turbulence.
  • the centrifuged individual fibers are transported by the air flow E without touching the shaft wall designed as an air baffle 4 to a perforated conveyor belt 5, on which they are deposited as a random fleece or as an oriented fleece 7, depending on the setting of the machine parameters, in particular the air parameters.
  • the deposited fleece 7 has a high uniformity in the fiber distribution and thus also the pile thickness.
  • the perforated conveyor belt 5 runs endlessly over a plurality of rollers 15, a cross-flow fan 11 being arranged within the circulating path of the conveyor belt 5, which over the entire width of the machine at the lower end of the air shaft 2 in a suction shaft 12 generates a uniformly adjustable negative pressure. Shortly after the fiber take-off point, this creates a negative pressure between 10 and 50 mm Ws.
  • This cross-flow fan 11 requires only a third of the performance of a conventional suction device and contributes significantly to the fact that a working width of, for example, 3.50 m can be made possible at all.
  • the suction shaft 12 between the conveyor belt 5 and the cross-flow fan 11 extends over the entire width of the machine.
  • the exhaust air flow of the cross-flow fan 11 is blown off via an exhaust air duct 13 which emerges laterally and is guided vertically upwards.
  • the cross flow fan 11 generates a suction flow F below the conveyor belt 5 with a specific volume between 50 and 100 m3 / (min ⁇ m).
  • This volume flow F corresponds to the air flow E in the lower part of the shaft 2.
  • the air flow E is composed of the air flow D also conveyed by the drum circumference and the additionally sucked-in air flow C from the upper part of the air shaft 2, the air flow C being composed either only of the through the inlet opening 6 of the duct 2 airflow A or composed of the airflow A and an additionally blown airflow B. If necessary, the additional air flow B can be blown in via a second fan 21 shown in FIG. 1, without thereby increasing the flow velocity of the resulting air flow E in the area of the fiber take-off zone 3.
  • FIG. 2 shows the drum T and the air duct 2 in detail.
  • the fleece fed to this reel can be fed via a carding section as shown in FIG. 1, but also via a feed roller with a feed trough in combination with a licker-in roller.
  • this second solution leads to a less good pile picture.
  • the card master segments C1 and C2 arranged on the drum T are provided with massive ribs 20 in order to avoid bending of the card master segments in the case of large machine widths.
  • the outermost ribbing 20 of the cardmaster segment C2 in the circumferential direction of the drum serves at the same time as an essentially rectilinear wall section 6 of the air shaft 2. In experiments it has been found that it is advantageous not to arrange a wedge terminating the carding area of the drum on the drum-side end of this wall section 6 , but to throw the fibers into the air flow immediately after leaving the card master segment area.
  • the air baffle 4 of the air shaft 2 which extends over the entire width of the machine, is curved such that the air shaft 2 is given an almost nozzle shape in cross section, with a narrowing in the form of a first throttle point 8 at a distance from the wall section 6 and the air baffle 4 Drum T is formed.
  • the throttle point 8 brings about an equalization of the air flow over the entire width of the machine.
  • the additional air flow B is blown in via a blast funnel 30 which extends over the entire width of the air shaft 2 and is conically narrowing in cross section and forms before the first Throttling point a dynamic pressure, which also helps to even out the air flow across the entire width of the machine.
  • the air baffle 4 has an aerodynamically favorable, namely continuous contour, which avoids air vortices even at high flow speeds.
  • the card master plates C1 and C2 can also be omitted and cover segments which have no carding function can be provided in their place.
  • the wall section 6 is designed from a sheet metal, which either runs essentially straight, as shown in FIG. 2, or is also curved symmetrically to the curved air baffle 4 on the opposite side of the shaft 2.
  • the wall section 6 of the air shaft 2 ends at its end on the drum side on a peripheral section of the drum approximately 10 to 15 ° above the horizontal plane through the drum axis.
  • the fiber removal zone 3 begins immediately after the card master segment 2, in which the air streams D and C and the spun-off individual fibers mix.
  • the air baffle 4 then forms a second throttle point 9 with the drum peripheral surface, from which the individual fibers can fly freely without touching the air baffle 4 without being able to get caught on the short outflow path to the conveyor belt 5.
  • the fibers lay down on the conveyor belt 5 to form a fleece and who which may be conveyed further with the aid of a take-off roller 22 at a take-off speed of 2 m / sec.
  • the lower part of the air baffle 4 can be straight and inclined in the direction of the vertical plane through the drum axis.
  • the knock-off knife 14 together with the trough 10 can be pivoted about the drum axis in such a way that the width of the lower shaft area 2b can be adjusted.
  • the knock-off knife 14 can assume a position parallel to the lower section of the air baffle 4 or a position that diverges conically from the air baffle 4.
  • the air baffle 4 can also be adjusted in the horizontal direction in such a way that the gap widths of the first and the second throttle point are changed.
  • the air baffle 4 can be pivoted so that the gap widths of the individual throttling points can be set independently of one another.
  • the gap width at the second throttle point can be set between 10 and 40 mm.
  • an airflow compression profile 25 which is preferably aerodynamically designed in cross section, can be arranged in the area of the first throttle point 8. This airflow compression profile contributes significantly to the homogenization of the air flow and thus to even out the formation of the fleece.
  • the airflow compression profile 25 can also serve to accommodate an ionizing device 26 which, at a high voltage of approx. 7 to 8 kV, electrostatically discharges the sucked-in air and thus prevents fiber agglomerations due to electrostatic forces.
  • a second ionizing device 27 can be arranged above the conveyor belt 5 behind the take-off roller 22.
