Definitions

  • the present disclosure relates to a fiber bundle condensing device of a spinning machine.
  • a spinning machine such as a yarn twisting machine and a roving machine, generally includes a drafting device that stretches or drafts a fiber bundle which is a material of a yarn and a fiber bundle condensing device that condenses the fiber bundle drafted by the drafting device.
  • the fiber bundle condensing device of a spinning machine also includes a suction pipe which has a guide surface and an air-permeable apron which is mounted on the guide surface of the suction pipe in a surrounding manner.
  • a suction slit is formed in the guide surface of the suction pipe (see Japanese Patent Application Publication No. 2008-95233 , for example).
  • the air-permeable apron moves while being in contact with the guide surface of the suction pipe.
  • the guide surface of the suction pipe wears gradually due to the friction with the air-permeable apron.
  • the guide member When attaching a guide member to a suction pipe, as described above, the guide member needs to be fixed to the suction pipe in order to prevent the guide member from moving while the fiber bundle condensing device is operating.
  • the conventional fiber bundle condensing device uses a screw to fix the guide member to the suction pipe, or otherwise an adhesive agent is applied to the suction pipe to fix the guide member.
  • an adhesive agent is applied to the suction pipe to fix the guide member.
  • such fixing means each have a problem as follows.
  • fixing the guide member to the suction pipe with a screw involves an increase in the number of parts or components used, leading to an increase in the cost. Furthermore, fixing with a screw complicates the structure of the fiber bundle condensing device, and such complicated structure may catch cotton fly easily.
  • the present invention has been made in view of the circumstances above, and is directed to providing a fiber bundle condensing device of a spinning machine that permits a guide member having a suction slit to be fixed to a suction pipe and also permits replacement of the guide member with ease.
  • a fiber bundle condensing device of a spinning machine that includes a suction pipe that is disposed downstream of a drafting device, and an air-permeable apron mounted on the suction pipe in such a manner as to surround the suction pipe.
  • the fiber bundle condensing device condenses a fiber bundle drafted by the drafting device.
  • the fiber bundle condensing device includes a guide member that is attached to the suction pipe at a position corresponding to a mounting position of the air-permeable apron and includes a guide surface adapted to guide movement of the air-permeable apron, and a suction slit formed in the guide surface; and a fixation tape to fix the guide member to the suction pipe.

  • the gear is engaged with an intermediate gear 20.
  • the intermediate gear 20 is engaged with a gear (not shown) that rotates integrally with the lower front roller 12a. With this configuration, the rotational force of the lower front roller 12a is transmitted to the lower nip roller 18a via the intermediate gear 20.
  • the upper nip roller 18b is pressed against the lower nip roller 18a via the air-permeable apron 15.
  • This pressing mechanism configures a nip portion 13a of the delivery portion 13.
  • the air-permeable apron 15 and a fiber bundle F are placed on the nip portion 13a of the delivery portion 13.
  • the upper nip roller 18b is supported by a pressing arm (not shown) via a support member 19 at every two spindle stations of the spinning machine.
  • the suction pipe 14 is disposed downstream of the drafting device 10. More specifically, the suction pipe 14 is disposed downstream of the delivery roller pair 12 of the drafting device 10 and upstream of the nip portion 13a of the delivery portion 13 in a direction X in which the fiber bundle F is moved (hereinafter, the moving direction X).
  • the suction pipe 14 is connected to a suction source (not shown) via a connection pipe 21.
  • the air-permeable apron 15 is an endless belt having no ends, and formed of a woven fabric, such as the one having an appropriate air permeability.
  • the air-permeable apron 15 is mounted in such a manner as to surround the suction pipe 14, the apron guide 16, and the lower nip roller 18a so that the air-permeable apron 15 passes through the nip portion 13a of the delivery portion 13.
  • the air-permeable apron 15 transfers the fiber bundle F in the X direction while moving with the rotation of the lower nip roller 18a.
  • a tip end 22a of the suction nozzle 22 is located below the apron guide 16.
  • the suction nozzle 22 is adapted to suck the fiber bundle F discharged from the drafting device 10 when a fiber break has occurred.
  • a distal end (not shown) of the suction nozzle 22 is connected to a single pneumatic duct (not shown) which is common to all of the spindle stations of the spinning machine.

  • the first outer surface 31 is positioned so as to extend along the moving path of the fiber bundle F and formed in a curved shape protruding outward.
  • a plurality of suction holes 35 is formed in the first outer surface 31.
  • the suction holes 35 are arranged at predetermined intervals in the longitudinal direction of the suction pipe 14. The intervals correspond to the positions of the spindle stations.
  • Each suction hole 35 is formed in a slit shape extending in a direction crossing the longitudinal direction of the suction pipe 14.
  • the second outer surface 32 is formed continuously from a first side 31a of the first outer surface 31, having a curved shape protruding inward.
  • the third outer surface 33 is formed continuously from a second side 31b of the first outer surface 31, having a curved shape protruding inward.
