Definitions

  • the invention relates to a device for winding a thread on a bobbin tube with the features from the preamble of claim 1.
  • Devices of this type are used on textile machines, for example double-wire twisting machines, in order to wind up the threads supplied by the textile machine, for example on cross-wound bobbins.
  • the double traversing used serves to equalize the length and thus tension of the thread in the so-called traversing triangle before the thread entry into the bobbin periphery.
  • the invention has for its object to provide a device for winding a thread on a bobbin with the features from the preamble of claim 1 so that after clamping the thread end at one end of the bobbin tube when starting the winding process by driving the bobbin tube and Main thread guide and the compensating thread guide uses an automatic threading process, at the end of which the thread from the thread feed device via the first thread deflection device, the third thread deflection device and the second thread deflection device and runs the main traverse to the bobbin tube.
  • the basic idea of the invention is to first move the thread clamped at one end of the bobbin tube at a point between the thread feed device and the first thread deflection device in a direction parallel to the movement paths of the two traversing thread guides until it has overflowed the first fixed thread deflection device.
  • This movement is effected at least in its second part by a first driver arranged on the second thread deflecting device connected to the main traversing thread guide, the thread being threaded into the second thread deflecting device.
  • the thread is then gripped by a second driver connected to the main traversing thread guide and moved back again.
  • Clamping the thread end at one end of the bobbin tube to initiate the threading process can preferably be carried out manually using a device such as that described in DE-OS 23 12 609 or automatically according to a method and a device described in the unpublished DE- OS 40 34 482 are described.
  • the thread deflection devices can be designed as thread deflection rollers. Furthermore, because of the small distances between the mutually changing parts, it has proven to be expedient for safety reasons if, in the area between the thread feeding device and the main traversing thread guide, a cover plate is arranged above the thread deflecting devices, which can consist, for example, of transparent material in order to visually control the processes enable.
  • FIG. 1 The device shown in FIG. 1 is assigned to a double-wire twisting spindle, of which the thread inlet tube 1, the bobbin pot 2 with the bobbin 3 inserted therein and the balloon limiter 4 are shown schematically.
  • the thread drawn off from the take-off spool 3 is passed out of the double-wire twisting spindle after passing through the thread inlet tube 1 and the driven thread storage disk, not shown, to form a thread balloon 5.
  • the thread balloon 5 finds its upper limit in the balloon thread guide 6 from which the thread F runs over deflection rollers 7 to the lead roller 8, which is attached to an externally driven shaft.
  • the deflection rollers 7 and the balloon thread guide 6 are mounted on the carrier 9 of the machine frame.
  • the lead roller 8 represents the thread feeding device for the actual winding device.
  • first thread guide roller 12 which is fixedly arranged on the machine frame. From there the thread runs to a second thread deflection roller 14 which is connected to the main traversing thread guide 14.2. Between the first thread deflecting roller 12 and the second thread deflecting roller 14, the thread still runs over the third thread deflecting roller 13 representing the compensating traversing thread guide 15 is wound up.
  • the coil sleeve 15 is held in a coil frame between the coil frame arms 16.1 and 16.2, specifically via centering plates 18.1 and 18.2.
  • the coil sleeve 15 or the coil SP is driven by means of an externally driven friction drive roller 17.
  • the main traversing thread guide 14.2 is fastened to a back and forth movable thread guide rod 14.1, while the third thread guide roller 13, which represents the compensating traversing thread guide, is arranged on a thread guide rod 13.1 which can also be moved back and forth.
  • the path of movement of the main tracer guide is designated B1 in Fig. 1, that of the compensating tracer guide with B2.
  • FIG. 2 shows the positions of the three thread deflecting rollers in three different positions of the main guiding thread guide and the compensating traversing thread guide.
  • the left end position in FIG. 2 of the second thread deflection roller 14 and the third thread deflection roller 13 is shown with solid lines together with the fixed position of the thread deflection roller 12.
  • a middle position and the right end position of the thread deflection rollers 14 and 13 in FIG. 2 are shown in broken lines.
  • the principle of double traversing is that the main traversing thread guide has the full stroke a executes, while in the simultaneous phase the compensating baling thread guide performs half the stroke a / 2.
  • the full stroke a corresponds essentially to the length of the spool SP, and the path of movement of the compensating trailing thread guide with the stroke a / 2 takes place parallel to the trajectory of the main trailing thread guide in a region which lies essentially between the center and one end of the bobbin tube, the position shown in Fig. 2 right position of the third thread deflection roller 13 may already lie outside the end of the bobbin tube.
  • the thread runs in the arrow direction P1 to the first thread deflection roller 12 and is fed in the arrow direction P2 from the second thread deflection roller 14 via the main traversing thread guide (not shown) to the spool SP.
  • the length of the thread piece between the first thread deflection roller 12 and the second thread deflection roller 14 is the same in all positions of the main trailing thread guide and the compensating traversing thread guide.
  • FIG. 3 the device is shown in the threaded state, in which the thread F coming from the leading roller 8 around the first thread deflection roller 12, then around the third thread deflection roller 13 and finally around the second thread deflection roller 14, and then via the main traverse guide 14.2 Coil tube 15 to be fed.
  • the course of the thread F ' is indicated by dash-dotted lines before the beginning of the threading process.
  • the device for clamping the thread is located at the end of the bobbin tube 15 on the right in FIG. 3 and is thus opposite to the path of movement of the compensating muzzle thread guide, that is to say the third thread deflection roller 13.
  • the right end 15.1 of the coil sleeve 15 in FIG. 3 is referred to below as the "first end”.
  • the known device for clamping the thread is not explained in detail. It is sufficient to note that the thread end is clamped between the centering plate 18.1 and the first end 15.1 of the bobbin tube, as can be seen, for example, from FIG. 4.
  • a stationary thread overflow plate 19 is arranged between the lead roller 8 and the first thread deflecting roller 12 in the region lying on the right in FIG. 3 and opposite the first end 15.1 of the bobbin tube.

  • a first driver 21 is arranged on the second thread deflection roller 14, which as in the direction of the movement path on the second end 15.2 of the coil sleeve pointing finger is formed and has a rising end to its free end with a drain edge on the top 21.1 and a drain edge on the bottom 21.2.
  • the inner end of the trailing edge on the underside 21.2 opens directly into the second thread deflection roller 14.
  • a second driver 22 is arranged on the thread guide rod 14.1 in connection with the second thread deflection roller 14, specifically in the direction of the first end 15.1 of the bobbin tube 15.
