Definitions

  • the present invention relates to a method for separating dust from fiber material which is passed over a sieve-like surface, being exposed to a suction air flow passed through the sieve-like surface, and to an apparatus for carrying out this method.
  • r m is also known a proposal that an opening roller of an open-end spinning device supplied fiber tape as it is guided over a roll surrounding the opening sieve-like surface to restrain the fiber tuft (DE-AS 2,648,715).
  • This has the advantage over cleaning in the area of the lickerin of a carding machine that a very intensive removal of the dust is achieved, since at this point a supplied sliver is dissolved in individual fibers.
  • the fiber beard since the fiber beard is still retained here, the dust located between the fibers is stripped off by the clothing of the rotating opening roller. The dust detached from the fibers in this way is then removed by the suction air.
  • this known device too, there is a risk that fiber residues, dirt particles, etc., get stuck on the screen-like surface and thus impair the dust separation.
  • the object of the present invention is therefore to create a method and a device for separating dust from fiber material, in particular on open-end spinning machines, in which this risk of clogging of the screen-like surface does not exist or is at least considerably reduced.
  • suction air flow to which the fiber material is exposed in the area of the sieve-like surface, counteracts at an acute angle set to the fiber transport direction is guided away from the fiber material.
  • This orientation of the suction air flow which has a movement component opposite to the direction of fiber transport, prevents flight, fiber remnants, shell particles, nits etc. from getting stuck in the sieve-like surface. Due to the inertia, the fibers and dirt particles retain their previous flight direction along the wall containing the screen-like surface. Only the micro-dust particles, which are practically inert due to their small mass and can therefore easily make this change of direction, follow this suction air flow through the sieve-like surface.
  • a particularly intensive cleaning is possible if the fiber material is held in the area of influence of a clothing roller by the sieve-like surface while it is exposed to the suction air flow.
  • a further intensification of the fiber material is achieved if it is parallelized before it is exposed to the suction air flow.
  • a stronger relative movement between the clothing and the fiber material to be cleaned is possible, whereby not only the dust that is already on the surface of the fibers or detached from the fibers is sucked off, but also dust is scraped off the fibers carrying them, so that also this dust can be removed by the suction air flow.
  • the fiber material is fed to the clothing roller, which is designed as a opening roller, in the form of a fiber sliver consisting of parallelized fibers.
  • the fiber material is still retained in the clamping line of the delivery device in the form of a fiber beard while it is exposed to the suction air flow. This further intensifies the stripping effect, which leads to a thorough cleaning of the fiber material. This is extremely important in open-end spinning, since the fiber composite is interrupted in the spinnon, so that any dirt can lead to considerable impairments in the spinning process.
  • a jet of air is briefly on the side facing away from the fiber transport path the screen-like surface is directed. This causes these components to be lifted off the sieve-like surface, so that the dust separating device can perform its task perfectly.
  • the cleaning interval for the screen-like surface can be matched to the work process of the textile machine or device to which the subject of the invention is applied so that this work process is not impaired.
  • the screen openings of the screen-like surface are inclined at an acute angle opposite to the fiber transport direction. This ensures that the suction air flow, which acts on the side of the sieve-like surface facing away from the fiber transport path, can suck off the dust detached from the fibers, but without larger particles such as dirt or fibers being able to become lodged in the sieve openings.
  • the screen openings are designed as elongated holes which extend essentially transversely to the fiber transport direction.
  • the screen-like surface is arranged in the peripheral region of a clothing roller.
  • the sieve openings designed as elongated holes are advantageously arranged at an angle to the transport direction such that - seen in the fiber transport direction - their ends towards an imaginary central Circumferential line of the clothing roller are inclined. In this way it is also achieved that light flight, which is captured by the air flowing through the sieve-like surface, is oriented in the direction of these sieve openings designed as elongated holes and thus passes through these sieve openings. This also reduces the risk of the screen-like surface becoming blocked.
  • lamellae are formed in the sheet metal by a combined deep-drawing / punching tool, which separate the elongated holes from one another and which are inclined in the fiber transport direction against the fiber transport path .
  • the inclined lamella can be formed in relation to the direction of fiber transport.
  • a blowing air nozzle is provided which is directed towards the side of the screen-like surface facing away from the fiber transport path and which is a short-term one Device generating compressed air jet is assigned.
  • the subject of the invention can also be used to measure the dust content in a fiber material.
  • an expanding dust collecting chamber with a plurality of filters arranged one behind the other is arranged with increasing fineness between the sieve-like surface and the suction air source. Since the filters or sieves which the dusty air passes first are coarser than the following filters or sieves, the finer particles of flight and dust are passed through the first sieve or filter and only caught on the one or the next filter, causing a separation different waste components is achieved.
  • the dust separation opening which is assigned an expanding dust collection chamber
  • a dirt separation opening which is assigned a dirt collection chamber
  • a fiber discharge opening which is assigned a fiber collection chamber
  • the invention makes it possible to remove dust from fiber material on a wide variety of textile machines and thereby avoids the risk of clogging of a screen surface which retains the fiber material against the action of a suction air stream. As a result, unchanged conditions with regard to dust separation are achieved for preparation machines and cards etc. even over longer periods of time.
  • open-end spinning machines which are very sensitive to dust accumulation
  • a screen surface designed according to the invention in the peripheral wall surrounding the opening roller in the area of the fiber material still retained by the delivery device as a fiber beard, not only blockages of the screen-like surface are prevented, but dust deposits in over long operating periods the collecting groove or on the open edge of the spinning rotor avoided, which prevents thread breaks.
  • the clothing roller in the range of which the screen-like surface is located, can be designed differently.
  • a sawtooth or needle roller e.g. in the opening device of an open-end spinning device or in the licker-in of a carding machine

  • the feed device 2 which can in principle be designed in different ways, has a delivery roller 20 and a feed trough 21 which cooperates with it.
  • the front end of the fiber sliver 1, which forms a fiber beard 10 is broken up into individual fibers 11 by the opening roller 3 and is fed in this form through a fiber feed channel 30 to a spinning element 31.

  • the fibers 11 reach the interior of the spinning element 31 for incorporation into the thread end from the fiber feed channel 30.
  • the fibers 11 are guided over the sieve-like surface 5, which covers the dust removal opening 4.
  • the individual fibers 11 are exposed to the action of the air vortex rotating in the direction of arrow 34 and the action of the air flow sucked through the sieve openings 50 into the dust separation opening 4.
  • This second air flow which separates dust and fiber material by inertial separation and to which the fiber material is exposed in the area of the sieve-like surface 5, is also at this acute angle due to the inclination of the sieve openings 50 at an acute angle 0 (opposite to the direction of fiber transport (arrow 34)
  • the individual fibers 11 are prevented due to the inertia and / or due to the combing action of the clothing rollers 35 from following this air flow oriented at an acute angle ⁇ opposite to the direction of transport Way to the fiber feed channel 30.
  • the practically inertia-free dust components have a high air resistance due to their small size and therefore have a lower sinking speed.Therefore, they can remain in the gas or air-borne state for a longer period of time and with the air ewegung be transported.
  • the Dust particles thus follow the change in direction imposed by the air flow and pass through the screen openings 50 to the filter 42, where they are collected.
  • the filter 42 is replaced or cleaned from time to time with a new one.
  • a particularly intensive dust separation is achieved if the dust is extracted from the fiber material in the area of the fiber transport path in which it is detached from the fibers 11 anyway. This is the case in the dissolving area, where the fiber material is still retained by the feed device 2 as a fiber beard 10.
  • the fiber sliver 1 is dissolved into individual fibers 11, the mechanical stress on the fibers 11 on the clothing tips 35 of the opening roller 3, the friction of the fibers 11 against one another and on the guide surface and the friction of the fibers 11 on the wall of the housing 32 cause dust the surface of the fibers rubbed and released.

  • a blower air nozzle 44 is provided in FIG. 2 in the feed trough 21, which is directed in the opposite direction to the air flowing through the screen-like surface 5 against the side of this surface 5 facing away from the opening roller 3.

  • This control device has, for example, a valve which briefly connects the blown air nozzle 44 to the compressed air side of the suction air source 43, which generates the negative pressure in the dust removal opening 4.
  • the control device can be controlled in different ways. It is thus possible for the control device to emit periodic control pulses for controlling a valve upstream of the blown air nozzle 44.
  • a vacuum measuring device can also be assigned to the dirt separating opening 4. If, by partially covering the screen openings 50, the negative pressure leaves a predetermined tolerance range, the compressed air is hereby released via the control device.
