Definitions

  • the invention relates to an open-end spinning machine with a machine frame, on the outside of which open-end spinning units are arranged, each of which consists of a spinning housing which is open at the front with a spinning rotor therein and an air discharge opening connected to a central air discharge duct, and an opening housing which can be folded down relative to the spinning housing Opening roller, a dirt separating opening and a dirt removal duct, whose outlet opening opening on the wall of the opening housing facing the machine frame adjoins a connecting pipe and is connected via this to a further central air outlet duct.
  • An open-end spinning machine with spinning units which consists of spinning housings attached to a machine frame and opening housings that can be hinged down, is e.g. known from DE-AS No. 1535005. From DE-AS No. 2023234 and DE-OS No. 2327663 the arrangement of a cleaning opening in the opening housing is known, to which a dirt discharge duct connects, the outlet of which is communicatively connected by means of a connecting pipe to a central air discharge duct provided in or on the machine frame .
  • the spinning housing has an outlet opening, which is also connected by means of a connecting tube to a central, either independent or common air discharge duct which discharges the working air from the spinning rotor.
  • the connecting pipes, which are connected to the central air discharge duct are arranged on the wall of the machine frame.
  • the present invention has for its object to ensure the removal of dirt from the region of the cleaning opening of a opening housing which can be folded down from the spinning housing in such a way that a return of dirt to the opening roller is prevented, while at the same time the collection of fibers at the transition between the air or dirt removal channels of the spinning units to the Connection pipes to the central air discharge duct is prevented without impairing the simple manufacture and assembly of the open-end spinning machine.
  • this object is achieved in that the axial depth of the dirt discharge channel from the dirt separating opening to the outlet opening is essentially the same size and that the end section of the connecting tube attached to the machine frame adjacent to the outlet opening is flared such that it surrounds the outlet opening at a distance. so that there is an air gap between the outlet opening and the inlet opening of the end section.
  • An advantage of the arrangement according to the invention is that the axial depth of the dirt drainage channel from the cleaning opening corresponds to the axial depth of the cleaning opening leading out of the cavity that supports the opening roller, thereby reducing the undesired influence the channel walls on the return of dirt to the opening roller is substantially eliminated.
  • An advantageous embodiment of the invention consists in that the outlet opening of the dirt discharge channel is provided on a nozzle protruding from the wall of the opening housing facing the machine frame, the outer circumferential wall of which tapers conically towards the machine frame, and that the end section of the connecting tube is in the working position of the opening housing circumferential distance is placed on the pipe socket.
  • the outlet opening in the wall of the opening housing facing the machine frame and the air discharge opening of the spinning housing which have axes running parallel to one another, are at a distance from each other, planes running perpendicular to the axes of the openings, this distance is greater than the distance between the axes of the two openings.
  • the distance between the outlet of the dirt discharge duct from the opening housing and the working air outlet from the spinning housing eliminates the unfavorable influence of the air flow escaping from the spinning housing.
  • the connecting tube is held in an elastic sleeve provided in the wall of the central air discharge duct and passes through an opening in the opening which is larger than the connecting tube Wall of the machine frame and through a holder arranged on the outside of the machine frame, which supports the connecting tube.
  • 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 in connection.
  • the machine frame 1 On its outside, the machine frame 1 carries known spinning units 3, each of which consists of a spinning housing 4 and an opening housing 5.
  • 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 out on the outside 12 of the machine frame 1.
  • a feed mechanism 13 for delivering sliver 14 on the other hand a opening roller 15 driven by a drive belt (not shown).
  • the cavity supporting the opening roller 15 16 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 opening housing 5.
  • the inner height H of the cross section of the discharge channel 19 is essentially the same from the cleaning opening 18 to the outlet 20 over the entire length of the channel.
  • the outlet 20 connects to the central air discharge duct 2 for removing contaminants.
  • 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 tube 22 has a larger internal 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 cured with three zen projections 23 is provided (Fig. 3).
  • the outlet 20 of the discharge duct 19 is located in the opening housing 5 and the discharge opening 9 in the spinning housing 4 is located in two different distances A from one another Levels, 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 impurities from the cleaning opening 18 of the opening housing 5 into the central air discharge duct 2.
