Definitions

  • the present invention relates to a cleaning device for a textile machine with a rotatable around a roll axis ⁇ ffnerwalze for opening presented fiber material and at least one Schmutzausscheideö réelle for discharging dirt material from the presented fiber material, wherein the Schmutzausscheideö réelle arranged in a region along the circumference of the ⁇ ffnerwalze and at her in the direction of rotation of the opener roller facing end is bounded by a cutting edge of a Kantelements, and wherein the edge member is disposed on a carrier which is pivotable about a support axis, so that the extension of the Schmutzausscheideö réelle along the periphery of the ⁇ ffnerwalze is variable.
  • 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 Type have rotating ⁇ ffneraggregate on.

  • 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.
  • the opened or dissolved fiber material together with the dirt now contained loosely on a cup-like arranged on the opening roller dirt removal through.
  • 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 debris material also contains a certain amount of Gutsfasermaterial, which is undesirable but unavoidable.
  • Schmutzausscheideötechnisch are openings in the housing 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 outlet, 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, formed or part of a spinning preparation machine, such as a blender 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.
  • the amount of the departure can be influenced by a variation of the distance of the cutting edge of the Kantelements of the ⁇ ffnerwalze.
  • This distance is set, the greater the amount of leaving.
  • a small distance leads to a relatively high degree of damage to the fiber material not discharged as waste and intended for further processing.
  • a cleaning device for a spinning preparation machine namely for a card, cleaning machine or the like
  • 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 knife and thus also its cutting edge are on a about a support axis arranged pivotable carrier.
  • a disadvantage of this known device is that during a pivoting movement of the carrier, the cutting edge of the shell blade is displaced at a constant distance or concentric with the circumference of the roller.
  • the amount of ejection can be influenced only by a change in the ejection distance.
  • the distance between the cutting edge and the opening roll always remains constant.
  • the amount of ejection in many cases can not be set to the desired value.
  • An increase in the pivot angle of the carrier, so the angle to which the carrier can be pivoted maximum, is possible at reasonable cost only up to a certain limit.
  • the amount of ejection is often higher than necessary, even if the ejection distance is set to the lowest possible value. This leads to an unnecessary material fiber loss per se. It often comes to an unnecessarily high impairment of the non-excreted fiber material, since the distance of the cutting edge of the opener roller is less than actually required.
  • 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. Conversely, the amount of ejection in a high contaminant fiber feed is often less than desired.
  • Object of the present invention is to propose a cleaning device, which offers an improved adjustment of the required for the cleaning of the supplied fiber material outgoing.
  • the cleaning device should be structurally simple and contribute to a reduction of Gutfaserbates and to a reduction of fiber damage.
  • the carrier axis of the carrier and the roll axis of the opening roll extend parallel to one another and thereby have a lateral offset.
  • the offset is a vectorial size, which is determined by its amount and its direction.
  • the amount hereby marks the distance between the carrier axis and the roll axis, while the direction defines the relative position in space.
  • the amount and the direction of the offset are chosen so that a pivoting movement of the carrier, which leads to an increase in the extent of the Schmutzausdorfmaschinetechnisch along the circumference of the ⁇ ffnerwalze, at the same time leads to a reduction of the distance of the cutting edge of the ⁇ ffnerwalze and vice versa.
  • the tilt angle of the carrier is at least 10 °, preferably at least 20 °, particularly preferably at least 30 ° is. As a result, a sufficient adjustment range can be ensured in most cases.
