Definitions

  • the present disclosure relates to a fine spinning machine including a fiber bundle condensing device.
  • Some fine spinning machines include a fiber bundle condensing device that condenses a fiber bundle drafted by a drafting device before the fiber bundle is twisted.
  • the fiber bundle condensing device is intended to improve yarn quality by, for example, reducing fluff in a yarn.
  • 2008-095233 (also published as EP 1 911 865 A2 ) includes a nip roller pair disposed downstream of a delivery roller pair of a drafting device, a suction pipe disposed between the nip roller pair and the delivery roller pair, and an air-permeable apron mounted on a lower roller of the nip roller pair, the suction pipe, and a guide portion in a surrounding manner.
  • the air-permeable apron is mounted on the lower roller of the nip roller pair and pinched between upper and lower rollers of the nip roller pair, and by rotating the lower roller, the air-permeable apron is moved or rotated.
  • Japanese Patent Application Publication No. 2000-034631 describes a configuration in which a nip roller and a suction pipe are provided downstream of a delivery roller pair of a drafting device, and an air-permeable apron is mounted on the suction pipe in a surrounding manner.
  • the nip roller is pressed against the suction pipe on which the air-permeable apron is mounted so that the nip roller is brought into contact with the air-permeable apron. In this state, the nip roller is rotated and the air-permeable apron is moved or rotated.
  • Japanese Patent Application Publication No. 2000-170043 describes a configuration in which a nip roller pair including an upper roller and a lower roller is disposed downstream of a drafting device, a suction pipe is disposed upstream of the upper roller, and an air-permeable apron is mounted on the suction pipe and the upper roller in a surrounding manner.
  • the upper roller on which the air-permeable apron is mounted is pressed against the lower roller so that the upper roller is brought into contact with the lower roller. In this state, the lower roller is rotated and the air-permeable apron is moved or rotated.
  • a circumferential velocity ratio of a delivery roller pair to a nip roller pair that is disposed downstream of the delivery roller pair significantly influences on the yarn quality (e.g., fluff, unevenness, strength).
  • the yarn quality e.g., fluff, unevenness, strength.
  • optimum circumferential velocity ratio varies depending on the material of yarn.
  • the circumferential velocity ratio should preferably be modifiable in accordance with the material of yarn.
  • the technique described in Japanese Patent Application Publication No. 2008-095233 uses a small number of units for transmitting a rotational drive force from the lower roller of the delivery roller pair to the lower roller of the nip roller pair (hereinafter, also referred to as the lower nip roller), where a gear transmission mechanism is used for the transmission of the rotational drive force.
  • the technique described in Japanese Patent Application Publication No. 2000-034631 also uses a small number of units for transmitting a rotational drive force from the upper roller of the delivery roller pair to the nip roller, where a drive belt is used for the transmission of the rotational drive force. In this case, each time the circumferential velocity ratio is modified, a large number of parts or components need to be replaced.
  • the suction pipe is disposed on the same side as the upper roller (i.e., on the upper side), and a fiber bundle is moved below the suction pipe.
  • the condition of condensation of the fiber bundle cannot be checked visually or by a similar method during an operation of the fine spinning machine, which delays detection of a failure or a trouble.
  • the upper roller is made of a rubber, the circularity or the like of the upper roller may be disturbed by wear. Grinding such worn upper roller to correct the circularity changes the diameter of the upper roller and causes a deviation of the position of the suction pipe, lowering the yarn quality. This is another problem.
  • roller diameters In the technique described in Japanese Patent Application Publication No. 2000-034631 , when the upper and lower rollers of the delivery roller pair are ground periodically, the ratio of the diameter of the upper roller to that of the lower roller changes before and after grinding, and the circumferential velocity ratio changes, accordingly. Therefore, in order to prevent lowering of yarn quality associated with grinding of rollers, roller diameters must be controlled strictly by, for example, grinding the upper and lower rollers at the same time.
  • JP 2005 - 082 956 A and DE 197 08 410 A1 disclose further prior art.
  • the present disclosure has been made in view of the above problems, and it is an object of the present disclosure to provide a fine spinning machine in which circumferential velocity ratio of the delivery roller pair to the nip roller pair of a drafting device is modifiable and changes in the circumferential velocity ratio associated with grinding of the rollers are reduced.
  • the fiber bundle condensing device includes a pressing mechanism configured to press the first driven roller or the second driven roller such that the first driven roller or the second driven roller is pressed against the first drive roller or the second drive roller forming the delivery roller pair and the nip roller pair, respectively, and against the air-permeable apron that is mounted on the suction pipe in a surrounding manner.
  • FIG. 1 is a schematic side view showing a configuration of a main part of a fine spinning machine according to a first embodiment of the present disclosure.
  • one side and the other side with reference to a feeding direction in which a fiber bundle is fed are referred to as upstream side and downstream side, respectively.

  • the suction pipe 5 is disposed upstream of the nip roller pair 7 and downstream of the front roller pair 2.
  • the air-permeable apron 6 is mounted on the suction pipe 5 and the apron guide 8 in a surrounding manner, but not mounted on the lower nip roller 7b.
  • the apron guide 8 is adapted to guide the movement of the air-permeable apron 6 while applying an appropriate tension to the air-permeable apron 6.
  • the nip roller pair 7 includes an upper nip roller 7a and a lower nip roller 7b.
  • the upper nip roller 7a is a rubber roller
  • the lower nip roller 7b is a metallic roller.

  • the relationship between the front roller pair 2 and the nip roller pair 7 is set such that the circumferential velocity ratio of the lower front roller 2b to the lower nip roller 7b is modifiable.
  • a configuration may be employed in which the lower front roller 2b and the lower nip roller 7b are individually driven to rotate by using separate drive sources.
  • a replaceable drive force transmitting mechanism for transmitting drive force of the drive source to the lower front roller 2b and the lower nip roller 7b may be employed.
  • the drive force transmitting mechanism for example, a gear transmission mechanism may be employed.
  • the lower nip roller 7b is the drive roller forming a pair with the upper nip roller 7a.
  • the upper nip roller 7a is pressed against the lower nip roller 7b at point A.
  • the upper nip roller 7a is pressed at point B against the suction pipe 5 on which the air-permeable apron 6 is mounted.
  • the air-permeable apron 6 is pinched at the point B between the guide surface 5a of the suction pipe 5 and an outer circumferential surface of the upper nip roller 7a.
  • the fiber bundle drafted by the drafting device 1 is condensed by the fiber bundle condensing device 3, the drafted fiber bundle is pinched between the upper nip roller 7a and the air-permeable apron 6 and between the upper nip roller 7a and the lower nip roller 7b.
  • FIG. 2 is a schematic side view for explaining a configuration of a pressing mechanism for pressing the upper nip roller 7a of the fine spinning machine according to the first embodiment of the present disclosure.
  • a pressing mechanism 11 includes a spring member 15 and a holder 16 attached to the spring member 15.
  • the spring member 15 is made of a leaf spring that is bent into a specified shape.
  • a fixed end (upper end) of the spring member 15 is fixed to a weighting arm (not shown).
  • the holder 16 is attached to a free end (lower end) of the spring member 15.
  • the holder 16 is configured to support a rotating support shaft 7c of the upper nip roller 7a.
  • the rotating support shaft 7c is disposed so as to be concentric with the upper nip roller 7a.
  • the holder 16 has a support portion 17 adapted to support a rotating support shaft 7c of the upper nip roller 7a.
  • the support portion 17 is adapted to support the rotating support shaft 7c of the upper nip roller 7a by being engaged with the rotating support shaft 7c.
  • the suction pipe 5 and the lower nip roller 7b are arranged adjacent to each other in Z-direction. That is, the Z-direction herein corresponds to the direction in which the suction pipe 5 and the lower nip roller 7b are adjacent to each other.
  • the support portion 17 has a shape of a long hole which is longer in the Z-direction so as to permit the rotating support shaft 7c to move in the Z-direction.
  • the dimension of the support portion 17 or the long hole in the longer direction is greater than the diameter of the rotating support shaft 7c. Therefore, when the rotating support shaft 7c is engaged with the support portion 17, there is a clearance or a space in the support portion 17 in the longitudinal direction thereof.

  • a fiber bundle drafted by the drafting device 1 is fed to the fiber bundle condensing device 3 by the front roller pair 2.
  • the fiber bundle that is fed to the fiber bundle condensing device 3 is moved with the air-permeable apron 6 on the guide surface 5a of the suction pipe 5, nipped by the nip roller pair 7 and fed further to the downstream side by the nip roller pair 7.
  • the upper front roller 2a is rotated in accordance with the rotation of the lower front roller 2b, and the upper nip roller 7a is rotated in accordance with the rotation of the lower nip roller 7b. That is, the upper front roller 2a and the lower front roller 2b rotate at the same circumferential velocity, and the upper nip roller 7a and the lower nip roller 7b rotate at the same circumferential velocity.
