Definitions

  • the invention relates to a device for forming a thread reserve winding with a bobbin rotating around the bobbin tube, which engages with a centering shoulder in the inner diameter of the bobbin tube and is provided with slots for catching the thread, which extends from the circumference of the bobbin plate in one direction of rotation of the tube opposite sense run obliquely inwards.
  • the coil sleeve is accommodated between two coil plates rotatably mounted in the coil arms.
  • the coil plates usually have at least one inner shoulder which engages in the inner diameter of the coil sleeve.
  • One of the bobbin plates rotating with the bobbin tube is also provided with a thread catching device in order to transfer the thread after the bobbin change to the inserted empty tube, where some reserve turns are first formed before the actual winding of the bobbin takes place.
  • a thread suction device is also provided in the device according to EP-A-0 069 205, which picks up the continuously supplied thread after the spooling process is interrupted when the full bobbin is ejected until the Empty sleeve is inserted and the thread can be transferred to it.
  • a thread guide is assigned to the thread suction device receiving the spun thread, which on the one hand has the task of bringing the thread together with the suction device into the area of the thread catching device, and on the other hand, after the reserve has been wound, the thread is passed to the traversing thread guide handed over to carry out the winding of the coil.
  • the cutting off of the thread after it has been fixed in the thread catching device is carried out by a thread separating device which is preferably assigned to the thread suction device.
  • the object of the present invention is to create a device which enables the safe catching and fixing of the thread end during the production of a thread reserve.
  • the object is achieved in a device according to the preamble of claim 1 in that the slots extend to the inner centering shoulder.
  • the slots run in an arcuate manner in such a way that they form an acute angle at their entry with the circumferential tangent of the coil plate and open out in an approximately radial direction onto the inner centering shoulder.
  • two thread guide elements can be moved in the thread path extending from a thread take-off tube to a thread suction device, said thread guide elements presenting the thread of the thread catching device approximately parallel to the sleeve axis.
  • the first thread guide element at the same time brings the thread piece extending into the thread suction device into the area of a thread separating device, so that the cutting and thus short thread ends can also be achieved without additional means during the presentation.
  • the second thread guide element moves the thread for winding up the reserve winding away from the bobbin plate in the direction of the center of the tube and again towards the bobbin plate. This has the effect that the thread end is wound over by reserve turns and is thus fixed. Due to the features of subclaims 6 to 8, a simple and space-saving device is achieved, with which the individual spinning positions can also be operated when changing bobbins from an operating trolley.
  • the invention is not limited to open-end spinning devices, but can also be used with advantage in other spinning devices from which the thread is drawn off by a pair of draw-off rollers, regardless of the type of thread feed and the reserve formation.
  • the invention is described below in connection with an open-end spinning device as a thread delivery point. However, the description is limited to laying out the thread in front of the winding unit and forming the thread reserve winding.
  • the procedural steps preceding these measures, such as spinning on the thread returned from the bobbin, removing the piecing and changing the bobbin for an empty tube, are described, for example, in EP-A-0 069 205, so that it is not necessary to go into this again here.
  • FIG. 1 denotes the thread draw-off tube of an open-end spinning device, through which the spun thread F is drawn off continuously.
  • the thread is drawn off by a pair of draw rollers 2, 20.
  • a bobbin tube 3 with a bobbin plate 4 and its drive roller 30 are shown.
  • the bobbin tube 3 is held in a known manner by two bobbin arms which press it against the drive roller 30.
  • a bobbin 4 is rotatably supported, of which the bobbin 4 shown has a plurality of slots 40 serving as a thread catching device.
  • These slots 40 extend inwards from the outer circumference of the coil plate to a centering shoulder 41 which engages in the interior of the coil sleeve and thus centers it and holds it in the radial direction.
  • These slots are shown in FIG. 3 and form an acute angle a with the circumferential tangent of the coil plate 4 at their entry. However, they can also be arcuate, so that they open in approximately radial direction on the inner centering shoulder 41.
  • the handling and guidance of the thread F before and during its transfer to the bobbin tube 3 corresponds to the processes described in EP-OS 0 069 205.
  • the thread guide 5 shown there in FIG. 2 corresponds to the thread guide fork 5 in FIG. 1, which is arranged in front of the bobbin tube 3. The only difference is that the thread guide fork 5 cannot be moved.
  • the mouth 40 of the thread suction device 4 in EP-A-0 069 205 corresponds to the tubular thread suction device 6 connected to a vacuum source, not shown, which has a thread separation device 60 in the vicinity of its mouth. This separating device can be arranged inside the tube or, as shown in EP-A-0 069 205, also outside the tube.
  • the thread guide fork 5 is arranged in a stationary manner.
  • a first thread guide element 7 is provided near the outside of the bobbin plate 4, while a second thread guide element 8 is arranged on the side of the bobbin plate 4 facing the bobbin tube. Both thread guide elements 7 and 8 are pivotally attached to the thread suction device 6 so that they can grip the thread extending from the thread take-off tube 1 of the spinning device to the thread suction device 6.
  • the tubular thread suction device 6 can be swiveled from a thread take-up position, not shown, into the position according to FIG. 1, in which its mouth is located laterally from the outside of the bobbin plate 4, but still in front of the thread running direction thereof.
  • a thread separating device 60 is arranged in a stationary manner, expediently in the vicinity of its mouth, in order to keep the length of the thread end cut off within limits. Because the two thread guide elements 7 and 8 are fastened to the thread suction device 6, they can be moved with the thread suction device from an initial position into the vicinity of the bobbin plate and back again.
  • the thread guide elements 7 and 8 are arranged together with the thread suction device 6 and the thread guide fork 5 on a movable maintenance carriage and are accordingly positioned in front of the winding device of each spinning station in order to carry out the replacement of a full bobbin with an empty tube and the thread emerging from the spinning device to transfer to this empty tube.
  • the thread F drawn continuously by the take-off rollers 2, 20 from the thread take-off tube 1 first runs into the thread suction device 6, where it travels there in the thread guide fork on the path indicated by the broken line 5 is performed.
  • the thread guide fork 5 is located in the radial plane of the end face of the bobbin plate 4.
  • the first thread guide element 7 and the second thread guide element 8 are inserted into the Thread path moves so that the thread is gripped and, held by these two thread guide elements, the thread catching device 40 of the bobbin plate 4 is presented so that this thread piece is aligned approximately parallel to the sleeve axis.
  • the thread piece extending into the thread suction device 6 must be separated.
  • the thread suction device 6 is brought into the area of a thread separation device 60 which is arranged as close as possible to the suction opening of the thread suction device 6.
  • the arrangement of the thread separation device 60 can be arranged on the thread suction device 6 or, as shown schematically in FIG. 1, in the thread suction device 6.
  • the second thread guide element 8 is also moved into the thread path at the same time as the first thread guide element 7, so that the thread section lying between the first thread guide element 7 and the second thread guide element 8 is in a position in which it rotates the plane of the thread catch slots 40 crosses on the circumference of the bobbin plate 4 rotating with the bobbin tube 3 and is thereby captured by one of these slots and carried along by the bobbin plate.
  • the second thread guide element 8 is now moved away from the bobbin plate 4 in the direction of the center of the bobbin and back towards the bobbin plate for winding up the reserve winding.
  • the thread reserve is preferably wound up with spinning tension, in that the thread F is ejected, for example, from the clamping line of the pair of draw-off rollers or, as shown in FIG. 1, the pressure roller 2 of the pair of draw-off rollers is lifted by a distance a from its drive roller.
  • the spinning tension ensures that the thread reserve is wound onto the sleeve sufficiently tightly.
