Definitions

  • the invention relates to a method for separating the roving between the pressing fingers on the wings of a roving machine provided with a drafting machine and the full roving bobbins.
  • the roving When pulling off roving bobbins on a flyer, the roving is to be separated so that only a short, freely hanging roving piece remains on the press finger plate, while the other roving end is to be placed on the spool as far as possible in such a way that it is generally suspended in the subsequent transport of the bobbins does not fall off.
  • JP-A-197225 In order to reliably separate the roving between the pressing finger and the bobbin circumference when changing the bobbin, it has already been proposed (JP-A-197225) to issue a section of the roving between the delivery roller pair and the wing head by synchronously rotating the wing and bobbin when the delivery roller pair is stationary, this roving section by turning the bobbin while the wing is stationary and the delivery roller pair running in the area of the press finger and to tear off the roving by lowering the bobbin at the press finger slot.
  • this process requires independently controllable drives of the drafting system, wings and bobbins and leaves the torn roving end unsecured on the circumference of the bobbin, so that it can fall off when the bobbin is subsequently transported.
  • the present invention is therefore based on the object, when pulling roving bobbins on the flyer, to separate the roving, that is to say the fuse, so that the sliver end lies on the upper winding cone of the bobbin.
  • this object is achieved by that the roving machine is stopped in a position or runs out in a position in which the pressing fingers are located just below the upper reversal point of the last winding layer on the spool, that the non-rotating or outgoing coils and wings are then moved axially relative to one another in such a way that the pressing fingers are guided to just below the point of reversal of the first winding layer that the coils are then turned forward by at least half a turn, that according to the nature of the material to be processed, the fuses between the drafting system and the pressing fingers are loosened and that for the final separation process, the non-rotating coils and wings are moved axially relative to each other so that the press fingers are guided downwards.
  • Another advantage is that the method according to the invention does not require any additional device, which does not anyway is already present on the roving machine.
  • the required process sequence can be easily programmed on the control device of the roving machine.
  • the press finger advantageously has a bevel.
  • FIGS. 1 to 5 there is a drafting device 2 consisting of several pairs of rollers above a machine frame of a pre-spinning machine.
  • the machine frame 1 has a wing bench 3, in which a plurality of wings are rotatably mounted on their heads and driven by drive means, not shown .
  • These wings 4 each have a hollow wing arm, at the lower end of which a press finger 5 is pivotally mounted.
  • the machine frame 1 is provided with a guide 6, on which a bracket 7 is mounted such that it can be moved.
  • This console 7 is connected to a coil bank 9 which is pivotably mounted about a pivot point 8.
  • 4 coils 10 are mounted on coil spindles coaxially to the wings.
  • Piston-cylinder units 11, through which the coil bank 9 can be tilted away from the machine frame 1, are located between the console 7 and the coil bank 9.
  • the roving machine After completion of the roving bobbins 10, the roving machine is stopped in one position or runs down in a position in which the pressing fingers 5 according to FIG. 1 are located just below the upper reversal point of the last winding layer on the bobbin 10.
  • the non-rotating or outgoing coils 10 and 4 wings are moved axially relative to each other so that the Preßf fingers 5 are performed close to the point of reversal of the first winding layer.
  • the coils 10 are then rotated forward by at least half a turn, as shown in the direction of the arrow. From Fig. 4 it can be seen that thereafter the fuses 12 between the drafting device 2 and the pressing fingers 5 are loosened, depending on the nature of the material to be processed. After this loosening, the non-rotating coils 10 and wings 4 are moved axially relative to one another in the direction of the arrow in accordance with FIG. 5 so that the pressing fingers 5 are guided downward for the final separation process. The separation process is now complete.
  • the advantageous effect is achieved that the end of the fuse 12 'on the upper turn cone 14 of the bobbin 10, thereby preventing the roving from falling during a subsequent, hanging transport of the roving bobbins 10.
  • the pressing fingers 5 must be designed in such a way that it is ensured that the fuses 12 are not threaded out when the pressing fingers 5 are moved upwards or downwards.
  • the lower edge of the pressing finger 5 can advantageously be provided with a bevel 20 for better sliding on the upper winding cone 14, which results in an improvement in the process sequence.
  • the inventive method means that no additional devices are required; the individual process steps can be easily programmed on a control device already present on the roving machine.
