Definitions

  • the present invention relates to a cleaning device for a textile machine with a rotatable ⁇ ffnerwalze for opening fed fiber material, with at least one Schmutzscheidscheideö réelle for separating dirt material from the supplied fiber material, wherein the Schmutzausscheideö réelle arranged in a region along the circumference of the ⁇ ffnerwalze and at its in the direction of rotation Opener-roller facing end is bounded by a cantilever element, wherein the canting element is arranged on a support which is pivotable about a support axis, so that the extent of the Schmutzausdorfmaschinetechnisch along the periphery of the ⁇ ffnerwalze is variable, with a Schmutzabgangskanal, extending from the Schmutzscheideö réelle up a suction chamber extends, and with a dirt outlet passage associated with the air inlet opening for the entry of an air flow u ng. Furthermore, the present invention relates to a textile machine, in particular a carding or cleaning machine.
  • the raw cotton is delivered in pressed bales for spinning.
  • the unwanted dirt is firmly embedded in the raw cotton.
  • Cleaning devices of the type described here have rotating ⁇ ffneraggregate.

  • the mentioned ⁇ ffneraggregate be uniformly referred to as ⁇ ffnerwalze.
  • the opening, also called dissolving, of the fiber material transported along an opening roller is effected by a mechanical action of the driven opener roller on the fiber material. By this mechanical action at the same time dirt is released from the fiber material.
  • a portion of this fiber material is thereby discharged, for example, by gravity, centrifugal force or by an air flow through the Schmutzscheidscheideö réelle to the outside.
  • this discharged through the Schmutzausscheideö réelle dirt material which is also called outlet, a large proportion of dirt.
  • the fiber material not discharged through the dirt separation opening is ultimately cleaned.
  • the soil material also contains a certain amount of fiber material.
  • Schmutzausscheideötechnischeötechnische are openings in the region of the opening roller, which extend over part of the circumference of the ⁇ ffnerwalze and usually over the entire working width of the ⁇ ffnerwalze. It is possible to assign a ⁇ ffnerwalze several Schmutzausdorfmaschinetechnischeötechnischen. At its downstream end or at its end pointing in the direction of rotation of the opening roller, a dirt removal opening is usually delimited by a cutting edge of a tilting element. At the cutting edge, the actual separation between the cleaned fiber material and the tail, which contains a large part of the impurities. In addition to slotted sheets, perforated sheets, angle bars and grate bars with a triangular cross-section, mainly shell knives are used as edge elements today.
  • Cleaning devices comprising a ⁇ ffnerwalze and limited by a Kantelement Schmutzscheidscheideö Maschinen GmbH, as independent cleaning machines, such as coarse cleaner or fine cleaner, trained or part of a spinning preparation machine, such as a mixer or a card, which primarily serves other purposes may be.
  • a cleaning device can be arranged in the hopper or in the licker-on zone of a card. In the latter case, for example, the licker-in (Briseur) of the card is used as a ⁇ ffnerwalze in the sense of this application.
  • the cleaning effect of the cleaning device depends in particular on the proportion of the waste from the total fiber material supplied.
  • the departure can be adjusted in particular by a change in the extension of the Schmutzausscheideö réelle along the circumference of the opening roller, which is also called ejection distance.
  • the longitudinal extension of the Schmutzausscheideö réelle or the ejection distance is ultimately that part of the circumference of the ⁇ ffnerwalze over which a part of the transported fiber material can be detached from the ⁇ ffnerwalze to be discharged through the Schmutzausscheideö réelle.
  • the larger the ejection distance the greater the amount of the discharge.

  • a rotatable about a roll axis opener roller is associated with a Schmutzausscheideö réelle, which is limited at its pointing in the direction of rotation of the opener roller end by a cutting edge of a shell blade.
  • the shell blade and thus also its cutting edge are arranged on a carrier pivotable about a carrier.
  • a dirt outlet channel is provided which extends from the Schmutzscheidscheideö réelle to a arranged on the carrier suction. This in turn is connected at both end faces in each case to a suction line, so that the dirt material can be transported from the dirt separation opening to the suction chamber and discharged from there by means of the suction lines.
  • an air inlet opening for the entry of a supply air flow is assigned to the dirt outlet channel.
  • a disadvantage of this known device is that the air inlet opening is arranged so that at least part of the supply air flow reaches the region of the dirt separation opening. This creates turbulences that disrupt the separation between the cleaned fiber material and the finish.
  • contaminant particles already released from the fiber material it is possible for contaminant particles already released from the fiber material to be transported back to the opener roller. This is especially true for fine dirt particles, since they are subjected to only a small centrifugal force. As a result, the cleaning effect of the entire device deteriorates.
  • Fiber damage is understood, for example, as kinking, tearing or tearing off a fiber. Such fiber damage is undesirable because it is detrimental to the quality of the final product produced in a spinning mill.
  • a pivotal movement of the carrier results in the known device to changed flow conditions in the field of Schmutzscheidscheideötechnisch, so that also the type and intensity of turbulence in this area change.
  • the turbulence in one position of the wearer to an increase and in another position of the wearer to a reduction in the amount of waste. Therefore, a defined cleaning of the supplied fiber material by means of the known device is ultimately not possible.
  • Object of the present invention is to propose a cleaning device which avoids the disadvantages mentioned.
  • a conditional by the supply air flow disturbance of the cleaning effect is to be avoided regardless of the respective carrier position.
  • the cleaning device should be structurally simple and contribute to a reduction of Gutfaserbates, to improve the cleaning effect and to a reduction of fiber damage.
  • the dirt outlet channel is assigned a shielding element, which shields the dirt separation opening in such a way against the incoming air flow that an influence on the separation of dirt material by the supply air flow is largely avoided.
  • the shielding element is designed and arranged such that the supply air flow does not reach the region of the dirt separation opening.
  • the shielding element can counteract vortex formation and / or keep emerging eddies from the dirt separation opening fem. In this way, even fine dirt particles can be deposited via the dirt separation opening from the supplied fiber material. Also, an increase of the Gutfaseranteils in the deposited soil material can be avoided.
  • the optimal shape and arrangement of the shielding element can be determined for example by means of computer-aided simulation methods and / or by means of real experiments.
  • the cleaning device it is possible to optimally adjust the cleaning action, loss of material fiber and fiber damage at each position of the carrier, that is, at every possible adjustment of the longitudinal extension of the dirt separation opening.
  • the cleaning device is extremely simple.
  • the suction chamber is arranged on the carrier, so that it is moved in a pivoting movement of the carrier. This ensures that the dirt material can easily enter the suction chamber at any possible position of the wearer.

  • the maximum possible pivoting range of the carrier can be increased, since a collision of the shielding element with the carrier or an element arranged on the carrier, for example the suction chamber, can thus be prevented during a pivoting movement.
  • the flow conditions in the dirt outlet channel are automatically optimized taking into account the respective position of the carrier. As a result, the cleaning effect can be further improved.
