Definitions

  • the invention relates to a method and a device for depositing and separating a roving sliver in a roving machine with a driven Drafting system, with driven wings, with driven reel bench and driven Bobbins, in which after the end of the winding a spiral, falling winding around the bobbin and one around the lower winding cone running turn with subsequent, at least one roving be performed.
  • a method for interrupting the roving sliver is already state of the art as a prerequisite for the automatic lifting of full roving bobbins known (EP 0 409 755 B1). This procedure applies to long fibers Stopping the wing of the roving bobbin the relevant pressing finger of the wing in the lower conical area of the roving bobbin is brought to a to partially open the roving yarn. Then one partial rotation of the spool is carried out while the wing remains stopped, so that the interruption of the fiber sliver is obtained. The coil can then be removed from the coil bank.
  • Another prior art is a generic method and a generic device for separating from Vorgarnlunten (EP 0 698 678 A1). This process is defined by that after the spinning process the roving bobbins are raised so far that the press fingers touch the respective lower cone areas (Sleeve areas) of the wraps. Then the Roving bobbins rotated together with the wings so that subsequent deliveries wound up from the drafting systems under increased tension onto the roving bobbins and thereby be secured. In the following, the roving bobbins become relative lowered to the wings, thereby separating the roving lines in the Area between the respective lower winding areas of the winding and to reach the wings.
  • JP Hei-7-11524-A a method for separating the roving slags is known (JP Hei-7-11524-A), in which after finishing the roving a roving spool by a roving machine of the press fingers and the spool bank are brought into a mutual position in which a separation of the Roving lines were not carried out. Then the wings are in this position and the roving bobbins started again, separating the roving sliver is done automatically by lowering the coil bank.
  • the state of the art also includes a construction or a method for winding predetermined lengths of yarn into Layers on a spool (EP 0 386 519 A1).
  • predetermined yarn lengths always the yarn end on the spool a predetermined position on the coil and preferably also can always be reached in the same winding direction.
  • the present invention is based on the object of a method and a device for depositing and separating a roving sliver to create a roving machine, which requires little construction ensures an effective separation process, so that the roving bobbins automatically removed and light and reliable for further processing can be handled.
  • Fig. 1 shows a schematic side view of a wound with a bobbin 22 Roving bobbin 8 with a cylindrical bobbin 1, an upper one Cone 2 and a lower cone 3.
  • the method for Placing and separating a roving 5 of this roving spool 8 is now how follows in front of it:
  • the roving 5 is by means of delivery-free moving the roving bobbin 8 and the coil bank 10 by a subsequent distance F-G-H performed at the same time Reduce the roving twist in an intermediate area F-G.
  • the roving yarn 5 moves from E to E '.
  • the roving is then carried out, i.e. the separation of roving 5 in an increasing area G-H of the cylindrical coil former 1.
  • the line H-I moves the coil bank shown in FIGS. 3 and 4 with the Roving bobbins 8 in a doff position down.
  • the movement of the roving spool and the spool bank C in the section F-G-H advantageously takes place without further delivery of the roving sliver.
  • Fig. 2 shows in bottom view, partly in section, the individual process steps according to Fig. 1.
  • FIG. 3 is a schematic side view of a roving machine or its Work organs shown, namely drafting system 20 with drive 21, wing bench 14 with wings 15 and drive 16, bobbin 10 with drive 11 and bobbin 22 with roving and bobbin drive 18. It is therefore a roving machine with separately controllable drives for the individual aforementioned Work organs.
  • a control device 25 Application which, as shown in Fig. 3, with the individual drives 11, 16, 18 and 21 is connected. This makes it possible without further equipment in a known roving machine using only the control device 25 1 and 2 for depositing and separating a roving sliver perform.
  • Fig. 4 shows another possibility of a roving machine in side view in schematic representation.
  • an overall drive 35 which for the drafting system 20, the wings 15, the bobbin 22 and the bobbin bank 10 serves.
  • a control device 25 ' is used, which with the Total drive 35 is connected to the control system.
  • this control device 25 ' are the individual clutches 27, 28, 29 and 30 for the working members controlled that in turn despite the overall drive of the individual work organs the roving machine the process steps mentioned above for storing and separating a roving 5 can be carried out.
  • the invention ensures that the ends of the Roving lines lie on the lower turn cone, which prevents that the roving falls off during a subsequent transport of the roving bobbins. It is therefore possible that these roving bobbins are automatically pulled off and can be further processed easily and reliably.
