  • the yarn joining device is formed as a splicer device that forms a splicing point by applying twists to the yarn ends by a swirling air current.
  • the yarn route regulating member bends a spun yarn by being in contact with the spun yarn during the yarn joining. The bent state of the spun yarn formed by the yarn route regulating member is maintained until winding of the spun yarn by the winding device is started.
  • GB 1 553 770 A describes a spinning machine, which includes two suction pipes, and a storage pipe.
  • the yarn, which is spun by a spinneret is reknotted in the event of a yarn break by a knotter.

  • the terms "upstream” and “downstream” refer to the upstream and the downstream in a travelling direction of a fiber bundle 11 or a spun yarn 10 when the spun yarn 10 is formed and wound in the spinning unit 1.
  • the motor box 4 is arranged on one side in the direction in which the plural spinning units 1 are arranged and it houses a common driving source for the spinning units 1.
  • the blower box 3 is arranged on the other side in the direction in which the plural spinning units 1 are arranged and the other side is the opposite side of the side on which the motor box 4 is arranged.
  • a blower is housed inside the blower box 3.
  • the blower functions as a negative pressure source that supplies the negative pressure to each of the spinning units 1 and the yarn joining carrier 2.
  • a compressor that functions as a compressed air source that supplies compressed air to each of the spinning units 1 and the yarn joining carrier 2 is arranged at a suitable location separated from the spinning machine 100. The compressed air is supplied from the compressor to the spinning machine 100 via one or more air pipes.
  • One or more regulators that adjust an air pressure of the compressed air are arranged in the blower box 3 or the motor box 4.
  • the compressed air to be supplied to the spinning machine 100 via the air pipes is supplied to each of the spinning units 1 and the yarn joining carrier 2 through the regulators.
  • the method of supplying the compressed air to the spinning units 1 and the yarn joining carrier 2 is not limited to the one explained here.
  • the spinning unit 1 is configured as an air spinning unit that performs spinning by applying twists to the fiber bundle 11 by the action of a swirling air current.
  • each of the spinning units 1 mainly includes, sequentially arranged from upstream to downstream, a drafting device 5, a spinning device 6, a yarn pooling device 7, and a winding device 8.
  • the fiber bundle 11 conveyed from the drafting device 5 is spun by the spinning device 6 thereby forming the spun yarn 10
  • the spun yarn 10 is wound around a bobbin 81 by the winding device 8 thereby forming a package 82.
  • the drafting device 5 includes, sequentially from the upstream, four drafting rollers, namely, a back roller 51, a third roller 52, a middle roller 54 with a rubber apron belt 53 stretched thereover, and a front roller 55. Each of the drafting rollers is rotationally driven at a predetermined rotation speed. Moreover, the drafting device 5 includes an opposing roller arranged facing each of the drafting rollers. The drafting device 5 transports a sliver 12, which is the raw material of the fiber bundle 11, by nipping the sliver 12 between the drafting rollers and the opposing rollers thereby forming the fiber bundle 11 by stretching (drafting) the sliver 12 until a predetermined width is obtained.
  • the spinning device 6 is located downstream of the drafting device 5 and forms the spun yarn 10 by applying twists to the fiber bundle 11 supplied from the drafting device 5.
  • a device that applies twists to the fiber bundle 11 by using a swirling air current is employed as the spinning device 6 in the present embodiment.
  • the yarn pooling device 7 is arranged between the spinning device 6 and the winding device 8.
  • the yarn pooling device 7 includes a yarn pooling roller 71, a yarn hooking member 72, and an electric motor 73.
  • the electric motor 73 can rotationally drive the yarn pooling roller 71.
  • the yarn pooling device 7 functions as a kind of a buffer that temporarily pools the spun yarn 10 at a position between the spinning device 6 and the winding device 8.
  • the yarn pooling roller 71 is configured so as to temporarily pool the spun yarn 10 by winding a certain amount of the spun yarn 10 on an outer circumferential surface thereof.
  • the yarn hooking member 72 that can hook the spun yarn 10 is mounted on a downstream end portion of the yarn pooling roller 71.
  • the yarn hooking member 72 is supported in a rotatable manner relatively to the yarn pooling roller 71.
  • a permanent magnet is attached to any one of the yarn hooking member 72 and the yarn pooling roller 71, and a magnetic hysteresis member is attached to the other of the yarn hooking member 72 and the yarn pooling roller 71.
  • These magnetic means generate a torque against a relative rotation of the yarn hooking member 72 with respect to the yarn pooling roller 71. Therefore, only when a force exceeding this torque is applied on the yarn hooking member 72 (i.e., when a tension of a predetermined amount or larger is applied to the spun yarn 10), the yarn hooking member 72 is rotated relatively to the yarn pooling roller 71 whereby the spun yarn 10 wound around the yarn pooling roller 71 can be unwound.
  • the yarn pooling roller 71 and the yarn hooking member 72 are integrally rotated whereby the spun yarn 10 that has been wound around the yarn pooling roller 71 is not unwound.
  • the spun yarn 10 is pooled on the yarn pooling roller 71 when the yarn pooling roller 71 rotates.
  • the yarn pooling device 7 operates such that the unwinding amount of the spun yarn 10 increases when the yarn tension on the downstream side increases, and the unwinding amount of the spun yarn 10 decreases when the yarn tension decreases (when the spun yarn 10 is about to slacken). With this operation, the yarn pooling device 7 absorbs the slack of the spun yarn 10 and can apply an appropriate tension on the spun yarn 10 at any given time during the yarn winding. Furthermore, because the yarn hooking member 72 operates to absorb any variation of the tension applied on the spun yarn 10 between the yarn pooling device 7 and the winding device 8, the variation of the tension is prevented from affecting the spun yarn 10 between the air spinning device 6 and the yarn pooling device 7.
  • a yarn-route guiding member 74 that guides to the downstream side the spun yarn 10 pulled from the yarn pooling device 7 is arranged downstream of the yarn pooling device 7.
  • the yarn-route guiding member 74 guides the spun yarn 10, which is pulled out from an axial end of the outer circumferential surface of the yarn pooling roller 71, such that the spun yarn 10 passes over a line that extends from a rotation axis of the yarn pooling roller 71. Accordingly, when the yarn hooking member 72 is rotating in a state in which it has hooked the spun yarn 10, a substantially conical balloon 75 is formed between the yarn pooling roller 71 and the yarn-route guiding member 74 because of the revolving of the spun yarn 10.
  • the winding device 8 forms the package 82 by winding the spun yarn 10 around the bobbin 81 while traversing the spun yarn 10.
  • the winding device 8 includes a cradle arm 83 and a winding drum 84.
  • the cradle arm 83 is rotatably supported by a support shaft 86.
  • the cradle arm 83 is capable of rotatably supporting the bobbin 81 (or the package 82) around which the spun yarn 10 is to be wound.
  • the winding drum 84 is rotationally driven in a predetermined direction at a constant rotational speed. By rotating the cradle arm 83 with the support shaft 86 as a center, the outer circumferential surface of the supported bobbin 81 (or the package 82) can be brought into contact with or separated from the winding drum 84.
  • the bobbin 81 When the outer circumferential surface of the bobbin 81 (or the package 82) is brought into contact with the rotationally driven winding drum 84, the bobbin 81 (or the package 82) is rotated following the rotation of the winding drum 84 whereby the spun yarn 10 is wound on the circumferential surface of the bobbin 81 (or the package 82).
  • a traversing device 85 includes a traversing guide 87 that can hook and guide the spun yarn 10.
  • the traversing guide 87 is driven by a not-shown driving means to perform reciprocating movement in a direction that is parallel to the rotation axis of the winding drum 84. With this configuration, when the traversing guide 87 with the spun yarn 10 hooked thereby is caused to make the reciprocating movement while the winding drum 84 is rotating, the spun yarn 10 can be wound around the package 82 while traversing the spun yarn 10.
  • the winding device 8 includes a not-shown brake mechanism that applies brake to the rotation of the package 82.
  • the configuration of the brake mechanism is not particularly limited, and can include, for example, a brake shoe that contacts a member that integrally rotates with the package 82 and a pneumatic cylinder that presses the brake shoe to this member.
  • a yarn quality monitoring device 9 that monitors the quality of the spun yarn 10 is arranged between the spinning device 6 and the yarn pooling device 7.
  • the yarn quality monitoring device 9 monitors the state (thickness and the like) of the running spun yarn 10 by using an optical transmission-type sensor to detect a yarn defect (a place where there is an abnormality in the spun yarn 10) in the spun yarn 10.
  • the sensor with which the yarn quality monitoring device 9 monitors the spun yarn 10 is not limited to the optical transmission-type sensor, and can, for example, be an electrostatic capacitance-type sensor. A foreign matter included in the spun yarn 10 can be detected as the yarn defect.
  • the yarn joining carrier 2 includes the yarn joining device 20, a yarn catching section (a suction pipe 21 and a suction mouth 22), and a reverse rotation mechanism 29.
  • the yarn joining carrier 2 includes a not-shown carrier controlling section that controls various components of the yarn joining carrier 2.
  • the yarn joining device 20 includes a yarn joining section 25 that is constructed as a splicer device that forms a splicing point by applying twists to the yarn ends by the swirling air current.
  • the side of the yarn joining device 20 and the yarn joining section 25 closer to a yarn route, which is a running path of the spun yarn 10 shall be referred to as a front side and the side that is far from the yarn path shall be referred to as a far side.
  • the direction that extends from the front side to the far side, or vice versa, of the yarn joining device 20 or the yarn joining section 25 shall be referred to as a front-back direction.
  • each of the suction pipe 21 and the suction mouth 22 is rotatable in the vertical direction about a corresponding axis.
  • Each of the suction pipe 21 and the suction mouth 22 can catch a yarn end by suction by generating a suction air current at tip ends thereof.
  • the carrier controlling section rotates the suction pipe 21 and also generates a suction air current at the tip end thereof. Accordingly, the suction pipe 21 catches by suction the yarn end of the spun yarn 10 (the spun yarn 10) supplied from the spinning device 6. Simultaneously, the carrier controlling section rotates the suction mouth 22 and also generates a suction air current at the tip end thereof.

Accordingly, the spun yarn 10 on which the hold by the pair of the clamping members 96 has been released is pushed upstream of the yarn joining section 25 by a blow of the air current whereby the slack of the spun yarn 10 is removed so that it does not propagate further upstream.

  • the receiving member 62 is arranged on the movable member 96a at a position close to the second slit 16 in the upstream guiding plate 92 and perpendicularly to the upstream guiding plate 92.

  • the surface of the receiving member 62 is flat, and because the compressed air strikes obliquely on this surface, as shown in FIG. 9 , an air current that is substantially laminar can be easily formed near the surface of the receiving member 62. Accordingly, the spun yarn 10 upstream of the second slit 16 is effectively pushed toward the back side in a direction that is substantially parallel to the second slit 16 because of the air current flowing on the surface of the receiving member 62, and in this process, the spun yarn 10 is elongated and expanded.

  • the timing at which the air injecting device 61 starts the injection of the air can be set to a desired time point that is after the start of the yarn joining operation (after the clamping members 96 have started the hold) but before the clamping members 96 have released the hold. However, from the viewpoint of energy saving, it is preferable to start the injection at a timing immediately before the clamping members 96 release the hold.
  • the injection of the air by the air injecting device 61 is stopped after the winding by the winding device 8 has started.
