Definitions

  • the invention relates to a thread connecting device for a cross-wound textile machine according to the Preamble of claim 1.
  • Such thread connecting devices are for example known from DE 195 10 171 A1.
  • a winding connection and / or Automatic cop change activated. That is, first one Suction nozzle to the surface of the slowly against the winding direction rotating spool applied. After capturing the Upper thread swings the suction nozzle into its starting position, in the the suction nozzle opening below a splicer is positioned back.
  • the gripper tube has a swivel-mounted end for Example of a spring-loaded gripper pipe flap with a Thread laying hook. That cuts when swiveling up Gripper tube with the thread laying hook the tension path of the Oberfadens, take this thread with you and position it functional in the splicer. That is, the Gripper tube flap, which the bobbin thread during the Swiveling the gripper tube mechanically fixed and with her thread-laying hook takes the upper thread with her The gripper tube runs into the upper end position corresponding curve piece slightly opened so that the threads "tightened" in the splicer.
  • the gripper tube After cutting the splicing scissors, the remainder of the Suctioned through the looper tube. Subsequently swivels the gripper tube back into its starting position. When the gripper tube is swung down, it stays on one First, the gripper pipe flap guided in a curve is in one Position in the mouth of the gripper tube at least is partially open. The grab pipe flap closes that Gripper tube only after leaving the curve section under the Effect of the existing negative pressure or a corresponding one Spring element.
  • a disadvantage of this embodiment is that the risk is that if there is a thread break or a Cleaner cut comes while the grapple flap goes through the Curve piece is still open, the hook tube the thread in the Can suck in downward movement. Then if the thread at the subsequent thread break or cleaner circuit below the Thread tensioner is sucked in again, it can Wraps around the flap of the gripper tube come what a significant disturbance of the thread connecting means.
  • the The invention is therefore based on the object, the known To improve thread connecting devices.
  • the gripper tube flap is guided differently when the gripper tube is pivoted up or when it is pivoted down.
  • This has the advantage that when the hook tube is swiveled up in the laying phase of the thread into the splicer, the hook tube flap can initially be guided in such a way that the valve is lifted off the hook tube mouth. The threads are tightened. After the threads have been clamped in the splicer, the hook tube flap is closed. During the downward movement of the hook tube, the hook tube flap remains closed, so that the thread cannot be sucked in through the hook tube in the event of a thread break / start cut.
  • the closing movement of the gripper tube flap is not only achieved by the negative pressure present, but also by the control cam of the gripper tube flap resting on the slideway of the spring-loaded curve piece of the control link.
  • the guide device as set out in claim 2, has two separate slideways which correspond in succession to the control cam of the gripper tube flap.
  • control link consists in essentially from a basic body that has a holder is fixed stationary on the bobbin case, and one on Basic body with limited movability, spring-loaded curve piece. The curve piece will thereby by the spring element in a predetermined Home position positioned.
  • the curve piece as described in claim 4, a in the two reach the swivel path of the gripper tube has a separate slideway forming web, is mounted so that the control cam of the gripper tube flap when swiveling up deflected the gripper tube to the outside and thereby the The hook tube flap is lifted slightly from the hook tube mouth becomes.
  • the curve piece of the control link gives way to that Control cams of the gripper tube flap, which leads to the Grab pipe flap in addition to the negative pressure still acted upon by the spring-loaded curve piece and thus reliably held in the closed position at all times becomes.
  • the gripper tube has Area of the gripper tube mouth a notch through which after the Cut the splicers to dispose of the rest of the bobbin thread becomes. That is, through this notch in the area of Gripper pipe mouth is a disposal of excess Thread length is also given when the hook tube flap fully rests on the gripper pipe mouth.
  • FIG. 1 shows a front view of a textile machine which is generally designated by the reference number 1, in the exemplary embodiment an automatic winder.
  • Such automatic winding machines usually have a large number of similar work stations, in the present case winding stations 2, between their end frames (not shown).
  • the spinning reels 9 produced on a ring spinning machine are rewound to form large-volume cross-wound bobbins 15 on these winding units 2.
  • the packages 15 are by means of an automatically working service unit, preferably a (not shown) package changer, on a machine-long cross-coil transport device 21 and to a bobbin loading station arranged on the machine end or the like transported.
  • an automatically working service unit preferably a (not shown) package changer
  • Such automatic winder 1 also have a Logistics facility in the form of a coil and Sleeve transport system 3.
  • This coil and Sleeve transport system 3 run, on transport plates 8, Spinning heads 9 or empty tubes around.
  • Such an automatic winder 1 also has usually via a central control unit, via a Machine bus with separate workstation computers 29 of the individual winding units 2 as well as with one Control device of the service unit is connected.
  • the delivered spinning bobbins 9 are in the unwinding position 60, which are in the area of the transverse transport routes 6 to the Winding units 2 is, to large-volume cross-wound bobbins 15th rewound.
  • the individual winding units have how known and therefore only hinted at about different Facilities that ensure the proper operation of this Ensure jobs.
  • These facilities are for example, a suction nozzle 12, a gripper tube 25 and one Thread connecting device 10.
  • the thread connecting device 10 is preferably a pneumatic splicer educated.
  • the pneumatic splicer is regular Thread run somewhat reset and has an upper clamping and Cutting device 11 and a lower clamping and Cutting device 17.
  • Such winding units 2 also have more, not facilities shown in detail, such as a thread tensioner, a Thread cleaner, a waxing device, a Thread cutting device, a thread tension sensor and one Bobbin thread sensor.
  • Spooling device consists of a spool frame 28 which around a Pivot axis 13 is movably mounted and a device for has rotatable holders of a bobbin. During the winding process, the cheese 15 lies with it Surface on a grooved drum 14 and is over this Friction driven.
  • each winding unit 2 has a suction nozzle 12 and a gripper tube 25, which are each connected to a machine-long suction channel 37 via a suction air connection.
  • the suction nozzle 12 is pivotally supported to a limited extent about an axis of rotation 16, the gripper tube 25 about an axis of rotation 26.
