Definitions

  • the invention relates to a device for pulling a thread into the weft store of a weaving machine, in which weft thread is stored in turns on a stationary drum.
  • a weft store of a known type is used, for example according to DE-0S 31 23 760.
  • the weft 2 is inserted on the axis of the weft store 4 into a bore 413 of a shaft 41 and then deflected into a winding tube 41 ', from where it is then is deposited in several turns W on the storage drum 400.
  • the shaft 41 is driven by a controlled electric drive, not shown, inside the housing 40 ', which is mounted on a frame 40.
  • the storage drum 400 stands still; it is supported by bearings 412 on the shaft 41 and this by means of bearings 411 in the housing 40 '.
  • On the take-off side on the right in FIG. 1 of the drum 400 there is an annular brush holder 401 with an inwardly directed brush 402, which is intended to control the orderly removal of the weft threads from the drum 400. 1, the brush holder is provided with a slot 403.
  • a thread eyelet 60 and then an injector 44 with a tube 50 are attached to an axis with the weft thread store.
  • the injector 44 like an injector 43, is connected to the entry side of the weft thread store 4 by a line 42 each Compressed air supplied. From the outlet mouth of the winding tube 41 extends a curved guide tube 51 which is slotted on the inside 51 'to the injector 44.
  • the tube 51 is attached to a holder 52 on the housing 40'.
  • FIG. 2 shows the injector 43 on the weft thread store 4 in greater detail.
  • Compressed air passes through the compressed air line 42 into an annular space 420 and from there into the lower region of a valve 45 at the spring 454, which presses a tappet 452 upward against a sealing ring 453.
  • the annular space 420 is separated from the upper space 455 in the valve.
  • the valve is opened by depressing the button 451, compressed air can pass from the line 42 into the annular space 456 around the entry eyelet 431 of the weft thread store. An air flow thus arises in the bore 413 of the shaft 41, as a result of which a weft thread held in front of the entry eyelet 431 is drawn into the store.
  • the winding tube 41 ' is automatically brought into alignment with the inlet mouth of the curved guide tube 51 by a suitable control of the drive of the shaft 41.
  • the compressed air from the injector 42 then flows with the weft thread 2 through the winding tube 41 'and the guide tube 51 to the injector 44. If the injector 44 is simultaneously pressurized with compressed air, the thread is further through the eyelet 60 and the injector 44 in the pipe section 50 conveyed on.
  • the winding process can be initiated by actuating a stop finger 404 against the circumference of the storage drum 400 by the winding tube 41 'starting to rotate with the shaft 41.
