Definitions

  • the invention relates to an air jet weaving machine with a weft insertion nozzle arranged outside the shed and a weft deflection device arranged between it and the shed for keeping the weft away from the shed after a signal for stopping the loom as a result of a fault, and with a transport line carried by the sley.
  • a deflection device for the weft thread In a deflection device for the weft thread, the weft thread is deflected laterally into the shed pneumatically or mechanically transversely to its normal running direction and is taken up by a suction line.
  • a suction device In air jet weaving machines there is usually a suction device for the cut ends of the weft threads on the exit side of the weft thread from the shed, that is to say on the side of the weaving machine opposite the insertion nozzle.
  • a suction unit is usually also arranged on this page for space reasons in air jet weaving machines.
  • a hose line In order to convey the weft thread from the deflection device to a collecting container in the suction unit, a hose line is generally fastened inside the weaving machine. If such hose lines are also installed in a space-saving manner on a longitudinal member of the frame, for example, they can be a hindrance for cleaning or maintenance work.
  • a weft deflection device is known from European patent application 0 161 376A1, in which a transport line for the deflected weft is attached to the sley. The first part of this transport line runs perpendicular to the longitudinal extension of the reed. No further details are given about the further design and routing of the transport line, as mentioned at the beginning, as a rule a hose is used as the transport line.
  • the invention consists in that the transport line for the deflected weft thread, which runs parallel to the longitudinal extension of the reed, is accommodated in the reed profile in a reed profile which carries the reed.
  • weft thread could, for example, also be carried away in a hollow drive shaft of the sley.
  • the deflecting device for the weft thread comprises the blowing nozzle 7 directed from above onto the path of the weft thread 5, the funnel 23 in the reed profile 2 and the thread guide 90.
  • the reed I is fastened in the reed profile 2, with the guide channel 12 of the weft thread 5 being guided during the entry becomes.
  • the guide channel 12 is located during the weft insertion in the shed 15 formed by warp threads 13 and 14 stretched parallel to the reed I.
  • Below the reed is the channel 22 in the reed profile, which serves as a transport line for the weft after deflection.
  • the reed profile 2 is screwed to the shaft 4 of the sley via several levers 3.
  • blowing nozzle 7 directs the tip of the weft thread 5 in the direction of the inlet opening of the funnel 23, through which air is sucked in.
  • the suction air then flows with the deflected weft thread 5 through the cavity of the end piece 24, in which an injector 25, which is supplied by the line 26 with compressed air, can be arranged to support the suction effect at the inlet into the funnel 23.
  • the end piece 24 serves, as can be seen in FIGS. 3 and 4, on the one hand to deflect the thread in a direction parallel to the longitudinal extension of the reed profile 2 and on the other hand to seal the transport line 22.
  • FIGS. 3 and 4 On the right-hand side in FIGS.
  • the transport line 22 is to the receiver 30 open towards the suction channel 32 of the deflected weft thread 5 is deflected again. Since the reed profile 2 is moved back and forth with the reed I and the entire sley, the inlet opening of the suction channel 32 must be chosen so large that the outlet opening of the channel 22 is in every movement phase of the inlet opening of the suction channel without narrowing the cross section during the entire movement range of the sley faces.
  • An end piece 27 must be provided on the reed profile 2, which shields that part of the inlet opening into the suction channel 32 which is not covered by the outlet cross section of the transport line 22 from the ambient air. A seal 31 between the receiver 30 and the end piece 27 prevents false air from being drawn in in this area.
  • a suction elbow 36 according to FIG. 2 can also open into the receiving piece 30, with which parts of the weft thread are picked up from this side of the sley after the entry.
  • the deflected weft thread passes from the receiver 30 through the suction line 37 into the collecting container 34, which is finally connected to a blower 35 for generating the negative pressure in the suction lines 22 to 37.
  • FIG 2 shows a schematic overall overview of the deflection device, the transport line and the downstream disposal system consisting of a collecting container 34 and a blower 35.
  • the main nozzle 61 and the funnel 23 the weft thread 5 is deflected towards the end of the deflection process via the thread guide 90, which ensures that the weft thread is inserted into the scissors 8 in the foremost position of the sley after rotation by arrow 41 in FIG is cut off.
  • the main nozzle 61 through which the weft thread is supplied, is located together with the second main nozzle 62 in the dashed position 61 'or 62' close to the scissors 8.
  • the funnel 23 is in the position 23 '.
  • the deflection process ends when the weft thread is cut off.
