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 is given to stop the loom as a result of a fault.
- 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 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, for example, on a side member of the frame are mounted in a space-saving manner, as they can be a hindrance when cleaning or maintenance work.
- the invention consists in that a transport line for the deflected weft thread is accommodated within the sley. Since the weft thread must be deflected at the level of the entry nozzle or the reed, it is expedient to place the transport line directly below the reed profile in the shop profile in which the reed is clamped.
- a reed profile with an internal closed channel can also have the advantage that its stiffness against torsion and bending deformation is higher compared to an open reed profile.
- 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 1 is fastened in the reed profile 2, with the guide channel 12 of which the weft thread 5 is guided during the entry becomes.
- the guide channel l2 is located during the weft insertion in the shed l5 formed by warp threads l3 and l4 stretched parallel to the reed l.
- 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.
- the blowing nozzle 7 now switched on 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.
- An end piece 27 must be provided on the reed section 2, which ends into the part of the inlet opening that is not covered by the outlet cross section of the transport line 22 Shields suction channel 32 from the ambient air.
- a seal 3l between the receiver 30 and the end piece 27 prevents false air from being drawn in in this area.
- it can be made of plush.
- 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 piece 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 weft 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 4l in FIG is cut off.
- the main nozzle 6l through which the weft thread is supplied, together with the second main nozzle 62 in the dashed position 6l 'or 62' near the scissors 8.
- the funnel 23 is in the position 23 '.
- the deflection process ends when the weft thread is cut off.
