Definitions

  • ABSTRACT Method of and apparatus for removing impurities released from staple fibers on a separating device preceding an underpressure spinning chamber and delivering them into a collecting area.
  • the impurities are sucked away from the collecting area by underpressure produced by the pressure of air drawn off from the spinning chamber, a part of the air that is being drawn off from the spinning chamber being fed to the collecting area and dragging the impurities into an underpressure outlet tube 13 Claims, 4 Drawing Figures PAIENIEDBET 91m 3.163.641
  • the present invention relates to a method of and an apparatus for removing impurities released from staple fibers on a separating device preceding an underpressure spinning chamber and delivering them into a collecting area; the apparatus for performing said method is provided with an area for collecting the impurities to which there open one or more cleaning slots or channels, said slots or channels being connected to the area in which the combing out roller of the separating device rotates.
  • Another feature is that a part of air that is being drawn off from the spinning chamber is fed to the collecting area and drags the impurities into an underpressure outlet.
  • the sucking may be intermittent, if desired.
  • the collecting area is connected with the underpressure exhaust tube leading to the injector, the working medium of which is air that is exhausted from the space around the spinning chamber through the exhaust channel.
  • Another preferable embodiment has the collecting space formed by a cylindrical body with a longitudinal hole for the inlet of impurities, while one front face of the cylindrical body is covered and the other, i.e. the
  • outlet of the collecting area is connected to the underpressure exhaust tube.
  • blowing channels connecting the collecting area with the area of the case which is connected with the exhaust channel by means of the pressure channel; the blowing channels may be arranged tangentially in the cylindrical body, or they may be oriented towards the outlets of the collecting area.
  • the underpressure exhaust tube is provided with a funnel in the place where it joins the collecting area; an interrupter may be inserted into the pressure exhaust tube.
  • a further feature consists in that the inlet of the pressure channel is arranged in the exhaust channel and widens in the direction opposite the air stream drawn away through the exhaust channel.
  • FIG. 1 shows the spinning unit in axial section through the spinning chamber in a plane perpendicular to the axis of rotation of the combing-out roller;
  • FIG. 2 shows the spinning unit in a plane perpendicular to the section plane according to FIG. 1;
  • FIG. 3 is a detail of a section of the collecting area, the cleaning slots and a part of the combing-out roller.
  • FIG. 4 depicts a detail of the injector in sectional view.
  • a combing-out roller 11 In the body 1 of the separating device there is rotatably mounted a combing-out roller 11 with tips 111 adjacent to the combing-out roller 11 there is a feeding roller 12 for feeding the sliver 2 of staple fibers 21 (FIG. 3) to the combing-out roller 11.
  • the sliver 2 enters the separating device through the condensing fun nel l3, and a pressure platen 14 serves to press it resiliently against the feeding roller 12.
  • the combing-out roller 11 as well as the feeding roller are driven by known, and, consequently, not illustrated drive means.
  • the combing-out roller 11 projects into the outlet channel 15 the inlet of which is connected with the surrounding atmosphere, while the outlet leads through the cylindrical side wall of the projection 16 projecting into the known spinning chamber 3 and creating together with the adjacent part of the body 1 of the separating device an immovable cover of the spinning chamber 3.
  • the exhaust hole 161 for exhausting the spunyarn 20 is arranged in the axis of the projection 16.
  • the spinning chamber 3 is provided with a frustoconical slip wall 31, widening to form a so-called collecting surface 32; wall 31 can be further provided with ventilating holes 33 for creating the necessary underpressure within the area of the chamber.
  • the spinning chamber 3 is fixed to the shaft 34 that is supported by bearings 35, 36.
  • the shaft 34 is terminated by a pulley 37 engaging, under working conditions, with the belt 38 driven by means (not shown).
  • the yarn 20 is exhausted through the exhaust opening 161 by means of driven delivery rollers 51, 52 and is wound on a bobbin 5 (FIG. 1).
  • the area around the spinning chamber 3 is limited by the housing 4 out of which the exhaust channel 41 leads.
  • one or more cleaning slots 61 are arranged in the wall of the body 1 of the separating device, said slots 61 connecting the area in which the combing-out roller 11 rotates with the collecting area 6 formed by a cylindrical body 60 provided with a longitudinal hole oriented with respect to the body 1 in such a way that the cleaning slots 61 open into the said cylindrical body 60.
  • the thus-created collecting area 6 is connected with the underpressure exhaust tube 62 leading to the outlet channel 41 so as to form with it the injector 63 (FlGS.2 and 4), the working medium of which is the air bleeding through the outlet channel 41 out of the area created by the housing 4.
  • a preferred embodiment of the outlet of underpressure exhaust tube 62 from the collecting area 6 has the form of a funnel in one front face of the cylindrical body 60, the other front face being closed.
  • Another advantage of the apparatus is that a part of the cylindrical body 60 is placed in the housing 64 and provided with blowing channels 601 connecting the collecting area 6 with the area of the housing 64; the area of the housing 64 is connected with the outlet channel 41 by the pressure channel 65.
  • the inlet of the pressure channel 65 is arranged in the outlet channel 41 and widens in a direction opposite the direction of the air streaming through the outlet channel 41.
  • An advantageous arrangement of the blowing channels 601 in the cylindrical body 60 is a tangential one, as shown in FlG.3.
  • the channels may also be directed to the outlet of the collecting area 6.
  • the sliver 2 is fed by the feeding roller 12 to the rotating combing-out roller 11 combing and separating the staple fibers 21 from the sliver.
  • these fibers 21 reach the slip wall 31 of said spinning chamber 3 and its collecting surface 32 where they are deposited as a ribbon-shaped configuration that is twisted into yarn delivered through the exhaust hole 161 out side the spinning chamber 3.
  • the drawing-off of yarn 20 is performed by means of delivery rollers 51, 52; the bobbin 5 serves to take up yarn 20.
  • the impurities 22 contained in sliver 2 are shot up, by kinetic energy imparted by the combing-out roller 11, through the cleaning slot 61 into the collecting area 6. From area 6 they are sucked away through the underpressure exhaust tube 62, under the effect of the injector 63, into the outlet channel 41 and via this outlet channel outside the machine, e.g. into a suitable waste box.
  • the interrupter 66 which is not an indispensable part of the apparatus, helps the impurities 22 to be dragged along into the outlet channel 41.
  • an apparatus for removing impurities from staple fibers on a separating device preceding an underpressure spinning chamber and delivering them into a collecting area the improvement which comprises means for sucking the impurities away from the collecting area by underpressure produced by the pressure of air drawn off from the spinning chamber, said lastnamed means comprising a combing out roller in the separating device, and a cleaning slot open to the collecting area, said slot being connected to the area in which the combing-out roller of the separating device rotates.
  • Apparatus according to claim 4 comprising means connecting the collecting area to an underpressure exhaust tube leading to a source of underpressure, the working medium of which is air that is exhausted from the space around the spinning chamber through an exhaust channel.
  • the collecting area is formed by a cylindrical body within a casing, the body being provided with a longitudinal hole for the inlet of impurities, one front face of the cylindrical body being covered and the other, the outlet of the collecting area, being connected to the underpressure exhaust tube.
  • blowing channels are oriented towards the outlet of the collecting area.
  • Apparatus according to claim 8 wherein the inlet channel. of the pressure channel is arranged in the exhaust chan- 13.
