Definitions

  • the invention relates to an open-end spinning machine, comprising a machine frame with at least one central air discharge duct and spinning units arranged on the outside thereof, each of which, on the one hand, consists of a spinning housing with a spinning rotor and a discharge opening for discharging working air, and on the other hand, consists of a dissolving housing with an opening roller including a cleaning opening and a discharge duct for the removal of contaminants, the outlet of which runs to the outside of the opening housing is connected to the central air discharge duct by means of a connecting pipe.
  • the open-end spinning machine with spinning units consisting of hinged spinning housings and opening housings has become known, for example, from DE-AS 15 35 005.
  • DE-AS 20 23 234 and DE-OS 23 27 663 make known the arrangement of a cleaning opening in the opening housing, to which a contamination discharge duct communicating through its outlet by means of a connecting pipe with a central air discharge duct provided in or on the machine frame is connected .
  • the spinning housing is also connected to a central, either independent or common air duct for removing working air from the spinning rotor.
  • the exits of the channels leading out of the spinning and opening housing are at the inlets of those on the wall of the machine frame connected connecting pipes of the central air duct connected.
  • the cleaning opening and further, the A includes b Adjustskanal on to an external air duct; Contaminants are led into the flow in this duct and delivered through this into the central air duct.
  • Complicated air currents which are caused, among other things, by the fact that the walls of the discharge duct are inclined differently and mostly tapering in the direction of contaminant removal will result in the return of a contaminant portion.
  • Such a proportion returns not only from the one described in the aforementioned DE-OS 23 27 663 collection chamber, but also from the - external air duct according to the CH-PS 593 355 back, because this is also tapered in the direction of the impurity removal.
  • the present invention is based on the object, on the one hand, of solving the problem of removing contaminants from the cleaning opening in order to avoid their return, and, on the other hand, of catching fibers at the transition between the outlets from the spinning units and the inlets in the central one Eliminate air exhaust duct while maintaining the ease of manufacture and assembly of the open end spinning machine.
  • An advantageous embodiment of the invention is that the outlet of the discharge channel protrudes from the outer wall of the opening housing and the outer peripheral wall of the outlet is flared from the end of the outlet to the outer wall of the opening housing, the connecting tube with its flared inlet in the working position of the Opening housing is placed on the outer peripheral wall of the outlet.
  • Another characteristic feature of the invention is that the discharge of contaminants in the outer wall of the dissolver housing and the discharge opening for discharging working air from the spinning housing lie in two different planes which are at a distance from one another which is greater than the axial distance between them the outlet and the discharge opening.
  • the connecting pipe is held in an elastic sleeve provided in the wall of the central air discharge duct and passes through an opening in the wall of the machine frame and through a holder which is adjustably arranged on the outer wall of the latter.
  • An advantage of the arrangement according to the invention is that the cross-sectional height of the channel for removing contaminants from the cleaning opening at certain channels is equal to the cross-sectional height of this opening leading out of the cavity that stores the opening roller, which essentially has the undesirable influence of the channel walls on the return of contaminants to the opening roller belittles.
  • a further advantage is that the fibers are not caught in the area of the transition between the mentioned exit and entry, which means that this area is not clogged, since the additional suction air entrains fibers which accidentally fly out of the spinning room when the spinning unit is closed.
  • the open-end spinning machine consists of a partially illustrated machine frame 1 with a central air discharge duct 2 running along the entire machine. The end of this duct 2 is connected to a suction duct (not shown) of the spinning mill or to an independent vacuum source.
  • the machine frame 1 bears on its outside known spinning units 3, each of which uflettesgetude from a spinning housing 4 and A are made.
  • a known spinning rotor 6 is arranged in the spinning housing 4, the shaft 7 of which is mounted in a bearing bush 8.
  • the spinning rotor 6 is either provided with ventilation holes or a necessary working vacuum is generated by a common vacuum source provided on the machine. Nevertheless, the spinning housing 4 is always provided with a discharge opening 9 for discharging working air.
  • the discharge opening 9 is connected to the inlet opening of a connecting channel 10, which in turn is connected to a flow channel 11 for removing working air.
  • This inlet opening of the connecting channel 10 opens on the outside 12 of the machine frame 1.
  • a feed mechanism 13 for delivering sliver 14, and on the other hand a opening roller 15 driven by a drive belt (not shown).
  • the opening roller 15 bearing the opening roller 15 of the opening housing 5 is connected on the one hand to a feed channel 17 for supplying individual fibers to the spinning rotor 6, and on the other hand to a discharge channel 19 by means of a cleaning opening 18.
  • the outlet 20 of the latter opens onto the outside 21 of the
  • Dissolution housing 5 from.
  • the inner height H / of the cross section of the discharge duct 19 is essentially the same from the cleaning opening 18 to the outlet 20 over the entire duct length.
  • the outlet 20 connects to the central Lucasab Industriesun g scaled nal 2 for the removal of impurities.
  • the inlet 24 of the connecting pipe 22 is substantially conically widened and adjoins the outlet 20 of the discharge duct 19 on the outside 21 of the opening housing 5.
  • the end plane of the inlet 24 of the connecting pipe 22 has a larger inner cross section than the outlet 20 of the discharge duct 19, a gap being provided between the inlet 24 and the outlet 20 for additional air intake.
  • Such a gap 25 can be formed, for example, in such a way that the edge of the inlet 24 of the connecting tube 22 is provided with three short projections 23 / FIG. 3 /.
  • An advantageous embodiment of the outlet 20 is shown in FIGS. 1 and 2; the outlet 20 projects beyond the outer wall 21 of the opening housing 5 and its outer peripheral wall 26 widens substantially conically from the end to the outer wall 21 of the opening housing 5.
  • the connecting tube 22 is at least partially open the conical outer wall 26 of the outlet 20 is attached.
  • the flared inlet 24 of the connecting tube 22 can be provided with short projections, which creates a gap between the walls mentioned; alternatively, such projections can be provided on the outer peripheral wall 26 of the outlet 20.
  • the connecting tube 22 is held in an elastic sleeve 27 provided in the wall of the central air discharge duct 2, passes through an opening 28 in the wall of the machine frame 1 and furthermore through a holder 29 which is adjustably arranged on the outer wall 12 of the machine frame 1 by means of a screw 30 through.
  • this holder 29 With the help of this holder 29, the inlet .24 of the connecting pipe 22 can be inserted into the outlet 2Q of the discharge duct 19 and thus any manufacturing inaccuracies can be compensated.
  • the outlet 20 of the exhaust duct 19 are in the opening 5 and the casing 9 in A bstitutionsö Stamm Spinnge house 4 in two different planes, at a distance A from each other, which distance A is greater than the axial distance B between the outlet 20 and the discharge opening 9.
  • the embodiment described above ensures continuous removal of contaminants from the cleaning opening 18 of the opening housing 5 into the central air discharge duct 2.
  • the spinning unit of the open-end spinning machine according to the invention works as follows:
  • a fiber sliver is delivered to 14 of the opener roller 15 from which separates the fibers from the sliver 14 and in the p S eisekanal 17 are conveyed.
  • the fibers are carried by the air flow into the spinning rotor 6 and deposited there in the known manner in the form of a fiber ribbon.
  • This ribbon is then formed into yarn by rolling or twisting.
  • the air flow mentioned is caused by a negative pressure generated by known ventilation holes in the spinning rotor 6.
  • the air is discharged from the spinning rotor 6 through the connecting duct 10 into the through duct 11 provided in the machine frame 1.
