Definitions

  • the present invention relates to a roving bobbin carrier system for supplying roving bobbins on which a roving is wound at a roving frame to a fine spinning frame in a spinning mill and simultaneously returning roving bobbins on which the roving is unwound at the fine spinning frame as blank bobbins to the roving frame.
  • An automatic roving bobbin carrier system for conveying, the roving bobbins between a group of roving frames and a group of fine spinning frames has been developed to follow automation in the spinning mill.
  • a supply line for supplying the roving bobbins on which the roving is wound is provided between the group of the roving frames and the group of the fine spinning frames
  • a return line for returning the roving bobbins on which the roving is unwound is provided between the two groups as a common line to be used with the supply line or an independent line.
  • a residual roving is attached on most of the roving bobbins to be returned to the roving frames, and such roving bobbins cannot be used in the roving frames as they are. Accordingly, a residual roving removing device is provided in a part of the return line or a part of a line branched from the return line.
  • a running flock belt is provided to contact the roving bobbins suspended by bobbin hangers for conveying the roving bobbins in the carrier system.
  • the roving bobbins are released from the bobbin hangers, and are moved near suction slits extending in an axial direction of the roving bobbins to suck the residual roving and unwind the same.
  • these types of the residual roving removing devices are constructed to collectively treat several to several tens of roving bobbins.
  • a plurality of roving frames R1, R2, ... and a plurality of fine spinning frames S1, S2, ... are provided in the same shop.
  • a return line 2 for returning a plurality of roving bobbins B1 on which the roving is unwound from the fine spinning frames S1, S2, ... to the roving frames R1, R2, ... in a direction Y1.

  • a plurality of suction nozzles 52 of the same number as the roving bobbins B1 are provided aside the roving bobbins B1 in such a manner as to be movable vertically and horizontally toward and away from the roving bobbins B1.
  • An elongated retainer box 53 is provided to retain the suction nozzles 52 in such a manner that the suction nozzles 52 project toward the roving bobbins B1.
  • the retainer box 53 is horizontally movably mounted on a guide rail 60, and is driven by a screw shaft 61 and a driving motor 62 in such a horizontal direction as to advance toward and retract from an array of the roving bobbins B1.
  • the guide rail 60 is mounted on a vertically movable support 55 which is connected to an endless chain 56.

  • a nozzle portion of the pressure air inducing portion 76 is preferably inclined at a suitable angle such that the suction air flow is rotated in an untwisting direction of the residual roving R on the roving bobbin B1, so that the residual roving R is changed into an untwisted fiber Ra as shown in Fig. 4, and the untwisted fiber Ra is discharged through a suction hose 54a connected with the bracket 80 to a collecting device (not shown).
  • the retainer box 53 is first moved toward the array of the roving bobbins B1 in such a manner that the front end portions 52a of some of the suction nozzles 52 advance to contact the blank bobbins, if any, and in this case, the front end portions 52a of the other suction nozzles 52 contacting the roving bobbins having the residual roving are retracted in the retainer box 53.
  • Such a retracted position of the suction nozzles 52 is maintained by the engagement of the pawl 75 with the continuous groove 78.
  • the retainer box 53 is retracted by a distance of 5 - 10 mm, and is then vertically moved as rotating the roving bobbins B1 at low speeds, thus sucking the end of the residual roving into the suction nozzles 52. Then, as shown in Fig. 2, the retainer box 53 is further retracted to a position 53d, and the roving bobbins B1 are rotated in an unwinding direction of the residual roving R at high speeds, thus removing the residual roving R from the roving bobbins B1.
  • the construction of the residual roving removing device 50 is not limited to the above.
  • the vertical movement and the horizontal movement of the suction nozzles 52 may be effected by any other known moving means.
  • the suction nozzles 52 may be connected to a vacuum pump or the like.
  • a method of removing the residual roving a method of re-removing a residual roving on a flock belt of each roving bobbin may be added, or a method of detecting a residual roving amount with use of a residual roving sensor may be combined with the above-mentioned removing method.
  • roving bobbin B1 suspended by the bobbin hanger BH is carried along a carrier rail 110 in a direction perpendicular to a plane of the sheet of the drawing.
  • a residual roving sensor (not shown) such as an ultrasonic sensor or an optical sensor is provided to detect whether or not a residual roving still exists on the roving bobbin B1.
  • a lower supporting device 103 is provided just under the roving bobbin B1 to be stopped in the backup device 100.
  • the lower supporting device 103 is formed at its upper end with a pin 101 to be inserted into the lower hollow portion of the roving bobbin B1.
  • one or two fixed rollers 116 and one or two movable rollers 115 which can be moved toward and away from the roving bobbin B1 by a cylinder 114 are provided at a position corresponding to an upper portion of the roving bobbin B1, thus supporting the upper portion of the roving bobbin B1.
  • the roving bobbin B1 having a residual roving is rotatably supported by the lower supporting device 103 and the rollers 115 and 116.
  • a cutter device 160 is provided aside the roving bobbin B1 to be stopped in the backup device 100.
  • the cutter device 160 includes a cutter rail 162 pivotably supported to a pin 163 and adapted to be pivoted by a cylinder 165, a vertically movable support 161 mounted on the cutter rail 162 and adapted to be moved vertically by a cylinder 164, and a cutter blade 166 mounted on the vertically movable support 161 for cutting the residual roving on the roving bobbin B1.
