Definitions

  • the present invention relates to a method according to the preamble of claim 1 and to an apparatus for carrying out this method (US-A-196 44 593).
  • the increase in the restraining force can be effected in various ways, for example by intensifying the suction air flow entering the intake manifold.
  • intensifying the suction air flow entering the intake manifold As a particularly simple and also extremely effective measure, a retention of the thread according to claim 2 and optionally also according to claim 3 has been found.
  • An increase in the safety against cutting can be achieved according to claim 4 by an additional movement of the suction tube, which retains the thread to be cut by clamping.
  • the function to be triggered when a cutting fault occurs may vary.
  • a device independent of the thread cutting device a separation process is performed.
  • the tension in the thread section extending from the thread cutting device into the suction tube can advantageously be used in accordance with claim 8.
  • the increase of the retention force is exerted by means of friction force.
  • it can be difficult to exert a sufficiently large restraining force on a thread solely by negative pressure, for example in a straight tube.
  • a mechanical retention for example by means of a clamping device, a corresponding feed movement, including the necessary clamping device.
  • the frictional force is generated by wrapping one or more bodies. It is conceivable, for example, to redirect the thread through a plurality of bodies and in this way to produce a friction length that is sufficiently large in total. Another alternative is to wrap a cylinder, for example, simply or even several times and to keep the thread running from these cylinders at its loose end with different suction or holding forces. Here, a relatively small holding force on the loose thread end is sufficient to prevent inadvertent pulling out of the thread during the cutting process.
  • the principle of self-locking is used, as it is used for example on winches on sailing ships.
  • the wraps are helical.
  • the suctioned by vacuum thread is held simultaneously by the suction force and the frictional force.
  • this can be achieved, inter alia, by increasing the length of the loop. This is particularly easy in the wrapping of a cylindrical body possible where by adding individual turns the looped length is particularly easy to enlarge.
  • a device is used to carry out the method described above.
  • the thread restraining device which is preferably designed as a clamping device, causes the thread to be severed to be held taut and does not have the opportunity to give way and thereby make it difficult to sever.
  • this clamping device in the vicinity of the inlet mouth of the suction tube according to claim 18 whose effectiveness is particularly high, since the retained by this clamping thread receives no way to slacken due to a possibly longitudinal elasticity, thereby complicating the severing of the thread or even impossible do.
  • the clamping device is simultaneously formed as a shut-off valve, so that fluttering of the thread portion is avoided on the relative to the clamping device of the winding device side facing and thus an uncontrolled yielding of the thread during the cutting process.
  • a thread monitoring device for the thread extending from the winding device to the suction tube can be provided according to claim 22 or 23.
  • a control device triggers a suitable function in case of malfunction of the thread cutting device, so that correspondingly quickly remedy can be created.
  • At least one body deflects the course of the thread.
  • either one or more bodies can be used. It is conceivable, for example, the arrangement of a plurality of individual bodies, which form a labyrinth, which deflects the passing thread. By deflecting the used for restraint required friction force is then generated, which fixes the thread.
  • the body is a vacuum hose.
  • a hose is particularly easy to deform and thus adapt to the required geometry.
  • the passing thread may rest against the inner walls designed as friction surfaces, via which in turn the required frictional force is applied.
  • Another particularly advantageous embodiment provides to increase the retention force that is reduced by means of an adjusting device, the flow cross section in the region of the thread from the control device, at least during the cutting process.
  • the method according to the invention and the device according to the present invention in a simple manner bring about a substantial increase in the certainty that the thread section to be wound onto the empty tube is separated from the thread section extending into the suction tube. In this way it is prevented that extends from the winding device to the arranged on the maintenance device suction pipe, a thread section which is pulled by the continuation of their maintenance work completed maintenance device on parts of the adjacent jobs and there impaired the reliability or the subsequent further processing of Thread hindered, which has been wound onto the coils of adjacent jobs, so that occur in subsequent operations disorders.
  • the advantage is achieved that the necessary device is very simple in construction and thus inexpensive to manufacture and can be used.
  • textile machines can also be retrofitted with the device according to the invention with little effort.

  • the thread cutting device 6 has in the illustrated embodiment, a blade 60 with a thread cutting edge 600.
  • the blade 60 is angled outside the working range of the thread cutting edge 600 at right angles and thus has a mounting portion 601, with the aid of the blade 60 with the interposition of a spacer 61 am Spularm 40 is attached.
  • the thread F which has previously been wound in a known and customary manner with the aid of the mentioned maintenance device 3 and in per se conventional manner in the presentation device 2 is withdrawn by means of the take-off rolls 11 and 12 through the thread withdrawal tube 10 of the open-end spinning device 1 and via the thread guide 21 into the inlet mouth 200 of the aforementioned suction tube 20 and continuously discharged through this.
  • the maintenance device 3 now pivots the presentation device 2 from its not shown thread receiving position towards the catching device 47, of which one of the rotating fishing hooks 470 extending from the thread guide 21 to the inlet mouth 200 of the suction tube 20 substantially parallel to the axis of the empty tube H and thus substantially perpendicular to the orbit of the fishing hooks 470 extending thread section takes.
  • the thread section F '(FIG. 2) of the thread F grasped by the catch hook 470 of the catching device 47 which is in relation to the catch hook 470 on the side facing the empty tube H, is due to the training known per se the sleeve plate 400 between segments 401, which project beyond the empty tube H and are supported by the sleeve plate 400, and the peripheral surface of the empty tube H clamped and thereby secured. Then passes the current of the empty tube H using the take-off rollers 11, 12 supplied thread F in the nip L between the empty tube H and the winding roller 43 and will be wound up on the empty tube H.
  • the control device 9 In timing with the transfer of the held by the presentation device 2 thread F to the safety gear 47, the control device 9 outputs a control signal to the coil 83 of the thread restraint 8, which now causes the force acting on the thread F retaining force is increased compared to that Retaining force that was previously generated by the pressure prevailing in the intake manifold 20 vacuum.
  • the retention force is increased by bringing the clamping element 80 into its clamping position, in which it clamps the thread section F ", which extends from the catch hook 470 to the inlet mouth 200 of the suction tube 20.
  • This thread section F is pulled along and along the thread cutting edge 600 during the rotation of the catch hook 470, thereby severing the thread F.
  • the thread section F is prevented from clamping by a pinch Give train in the direction of thread cutting device 6.
  • the thread F has no possibility to yield during cutting, so that the thread section F "of the thread cutting device 6 to be cut is presented in a streamlined state, which leads to a high level of cutting safety.

  • the clamping element 80 may be designed such that in its clamping position substantially the entire inner cross section of the suction tube 20 is shut off and thus formed as a shut-off valve 85 (FIG. 3). The inner cross-section of the suction tube 20 is thereby blocked off as far as the thread section F "extending into the suction tube 20 permits, which is now clamped between the inner wall 201 of the suction tube 20 and the clamping element 80.
  • the suction tube 20 carries out an additional movement through which the thread F retained by the clamping element 80 both at the inlet mouth 200 of the suction tube 20 and at the thread cutting edge 600 undergoes even greater deflection and above all rests with an even higher contact pressure at the thread cutting edge 600. In this way, the security against cutting of the thread cutting device 6 is considerably increased.
  • the thread cutting edge 600 changes its cutting behavior over time. This gradual reduction of the cutting quality can be controlled poorly, as even with deteriorating cutting quality, a separation process is still performed due to the fact that arranged in the presentation device 2 retaining device 8, possibly in conjunction with an additional movement of the suction tube 20, the severing thread F keeps, so that despite a no longer perfectly cutting thread cutting edge 600 of the thread F is severed at least by tearing.
