  • the accumulation chamber is connected to an end of the main duct 37.
  • the fly-waste that flows through the main duct 37 is accumulated in the accumulation chamber.
  • the yarn accumulating device 12 is arranged downstream of the spinning device 9. As shown in FIG. 2 , the yarn accumulating device 12 includes a yarn accumulating roller 21 and a motor 25 that rotationally drives the yarn accumulating roller 21.
  • the yarn accumulating roller 21 temporarily accumulates the spun yarn 10 by winding a certain amount of the spun yarn 10 on an outer peripheral surface thereof.
  • the spun yarn 10 is pulled from the spinning device 9 and transported to the downstream side at a predetermined speed by causing the yarn accumulating roller 21 to rotate at a predetermined rotational speed with the spun yarn 10 wound on the outer peripheral surface thereof. Because the spun yarn 10 can be temporarily accumulated on the outer peripheral surface of the yarn accumulating roller 21, the yarn accumulating device 12 can function as a kind of buffer.
  • the buffering function of the yarn accumulating device 12 avoids troubles (for example, slackening and the like of the spun yarn 10) caused by a mismatch in a spinning speed of the spinning device 9 and a winding speed (the speed of the spun yarn 10 being wound into a package 45) due to some reason.
  • An upstream guide 23 is arranged little upstream of the yarn accumulating roller 21.

  • the yarn clearer 52 monitors a thickness of the running spun yarn 10. Upon detecting a yarn defect in the spun yarn 10, the yarn clearer 52 transmits a yarn-defect detection signal to a not-shown unit controller.
  • the unit controller Upon receiving the yarn-defect detection signal from the yarn clearer 52, the unit controller cuts the spun yarn 10 by stopping driving of the spinning device 9, and stops winding and the like by the winding device 13. The unit controller sends a control signal to the yarn joining cart 3 to cause the yarn joining cart 3 to travel to the spinning unit 2. After completion of yarn joining by the yarn joining cart 3, the unit controller drives the spinning device 9 again to cause the winding device 13 to restart the winding.
  • the yarn joining cart 3 includes a yarn joining device 43, a suction pipe 44, and a suction mouth 46.
  • the yarn joining cart 3 travels on a rail 41 and stops at a work position corresponding to that spinning unit 2.

  • the suction mouth 46 swings downward about a shaft to catch a spun yarn 10 from the package 45, and then swings upward about the shaft to guide the spun yarn 10 to the yarn joining device 43.
  • the yarn joining device 43 joins the spun yarns 10 guided thereto.
  • the winding device 13 includes a cradle arm 71, a winding drum 72, and a traversing device 75.
  • the cradle arm 71 is supported so as to be pivotable around a support shaft 70.
  • the cradle arm 71 rotatably supports a bobbin 48 on which the spun yarn 10 is to be wound.
  • the winding drum 72 rotates in a state of being in contact with an outer peripheral surface of the bobbin 48 or the package 45.
  • the traversing device 75 includes a traversing guide 76 that guides the spun yarn 10.
  • the winding device 13 drives the winding drum 72 with a not-shown electric motor while causing the traversing guide 76 to perform a reciprocating movement with a not-shown driving member. As a result, the spun yarn 10 is wound into the package 45 while traversing the spun yarn 10.
  • upstream and downstream in the explanation of the fly-waste removing section 30 refer to upstream and downstream, respectively, in a transportation direction (that is, a direction in which a suction current flows) of the rejection material.
  • the fly-waste removing section 30 includes, as shown in FIG. 3 , the section ducts 31, section blowers (section suction devices) 32, filter members 33, pressure detecting sections 35 (negative pressure detecting sections), the main duct 37, and a main blower (a main suction device) 38 (See FIG. 1 ).
  • the section blower 32 and the main blower 38 can be a suction device other than a blower.
  • the suction pipe 91 shown in FIG. 2 is provided for each of the spinning units 2.
  • the suction pipe 91 connects the spinning unit 2 to the section duct 31.
  • an upstream end of the suction pipe 91 is connected to the spinning device 9 (specifically, to a not-shown exhaust chamber formed downstream of the swirling current generating chamber) of the spinning unit 2.
  • the suction pipes 91 of a predetermined number (20 in the present embodiment) of the spinning units 2 are connected to one section duct 31.
  • 20 suction pipes 91 are connected to one section duct 31.
  • One section duct 31 is arranged for the predetermined number of the spinning units 2 (in the following explanation, the group of the predetermined number of the spinning units 2 will be referred to as a section).
  • the number of the spinning units 2 can be the same or can be different in different sections. Accordingly, the number of the suction pipes 91 and the number of the spinning units 2 connected to one section duct 31 can be the same or can be different in different section ducts 31.
  • Each section duct 31 is connected to the main duct 37 and to an exhaust duct 34 in the downstream side thereof. Accordingly, a suction current generated by the main blower 38 also acts inside the section duct 31.
  • the section blower 32 is arranged near the filter member 33 but inside the exhaust duct 34.
  • the section blower 32 has blades 32a that generate a suction current by rotating and a section blower driving section (a section driving section) 32b that drives the blades 32a.
  • the section blower driving section 32b is an electric motor and it is controlled by a section blower controlling section (a controlling section) 39.
  • One section blower controlling section 39 can be arranged in a controlling device that controls the entire spinning frame 1, or can be arranged in each section.
  • the filter member 33 is arranged at a connecting part of the section duct 31 and the exhaust duct 34.
  • the filter member 33 is a net.
  • the mesh of the net of the filter member 33 is set such that rejection material 81 cannot but air (a later-explained suction current 82) can pass through it.
  • the pressure detecting section 35 is arranged in a region between the filter member 33 and the section blower 32 but inside the exhaust duct 34.
  • the pressure detecting section 35 detects the pressure (the negative pressure) in this region.
  • At least the suction current 82 generated by the section blower 32 acts in this region.
  • the pressure detecting section 35 outputs a pressure detection signal to the section blower controlling section 39.
  • the section blower 32 sucks air from the section duct 31 via the filter member 33 thereby generating the suction current 82 inside the section duct 31, inside the suction pipe 91, and the like.
  • the suction current 82 is used mainly to move the rejection material 81, which is generated in the spinning device 9, via the suction pipe 91 to a downstream end of the section duct 31.
  • the suction current 82 that passes through the filter member 33 is exhausted to the outside via an outlet 34a of the exhaust duct 34.
  • the remaining suction current 82 along with the rejection material 81 flows into the main duct 37 via an opening 36 formed between the section duct 31 and the main duct 37. That is, in a state in which both the main blower 38 and the section blower 32 are being driven, a part of the suction current 82 in the section duct 31 flows toward the section blower 32 while the remaining part of the suction current 82 in the section duct 31 flows toward the main duct 37.
  • the section duct 31 and the main duct 37 are directly connected to each other.
  • the opening 36 is arranged in a connecting part of the section duct 31 and the main duct 37.
  • the opening 36 is arranged in a downstream end of the section duct 31.
  • the filter member 33 is arranged also in the downstream end of the section duct 31.
  • a member to open and close (a shutter and the like) the opening 36 is not provided. Accordingly, because of a suction current 83 flowing in the main duct 37, the fly-waste moves into the main duct 37 from the section duct 31 via the opening 36.
  • the main blower 38 is arranged near one end of the main duct 37 but inside the blower box 4 (see FIG. 1 ).
  • the main blower 38 generates a negative pressure downstream of the main duct 37 thereby causing the suction current 83 to flow inside the main duct 37.
  • the main blower 38 is always operated. That is, blades of the main blower 38 are always rotated during the winding.
  • the rotation of the main blower 38 is controlled by the section blower controlling section (the controlling section) 39.
  • a main blower controlling section can be provided separately from the section blower controlling section 39, and the rotation of the main blower can be controlled by this main blower controlling section.
  • the rejection material 81 is taken by this suction current 83 to the not-shown accumulation chamber (the cotton accumulation box) arranged at the one end of the main duct 37.
  • the fly-waste removing section 30 is configured so that a flow rate of the suction current 82 exhausted from the exhaust duct 34 is higher than a flow rate of the suction current 82 introduced into the main duct 37.
  • a power consumption of the main blower 38 can be reduced because the flow rate of the suction current 83 sucked by the main blower 38 can be set low.
  • the flow rate of the suction current 82 exhausted from the exhaust duct 34 can also be set lower than the flow rate of the suction current 82 introduced into the main duct 37.
  • a method to remove the rejection material 81 deposited on the filter member 33 is explained below with reference to FIGS. 4 to 7 .
  • a curve labeled "rotational speed" in FIG. 4 shows an example of time variation of the rotational speed of the blades 32a of the section blower 32.
  • the section blower controlling section 39 performs a normal control and a deceleration control.
  • the normal control is a control in which the blades 32a are rotated at a substantially constant rotational speed (within a predetermined speed range).
  • the section blower controlling section 39 performs the normal control not only when the spun yarn 10 is being wound but also when the winding of the spun yarn 10 is interrupted during the yarn joining and the like.
  • the "predetermined speed range” is a speed range of the rotational speed, in the normal control, after an increase from the rotational speed at the time of ending of the deceleration control.
  • the "predetermined speed range" is the speed, represented by the horizontal line of the curve, that is higher than the speed for the deceleration control.
  • the "predetermined speed range" can be a constant speed as shown in FIG. 4 , or can be varied within a predetermined range so that the average speed is equal to the speed shown in FIG. 4 .
  • the deceleration control is a control to maintain the rotation of the blades 32a while temporarily reducing the rotational speed of the blades 32a.
  • a control to completely stop the rotation of the blades 32a is not included in the deceleration control.
  • the present embodiment has been explained with the assumption that such an acceleration is carried out while the normal control is being performed. In the present embodiment, because only the normal control and the deceleration control are performed while the winding of the spun yarn 10 is being performed, the normal control and the deceleration control are performed alternately (in other words, the deceleration control is performed after the normal control, and the normal control is performed after the deceleration control again). Because the main blower 38 is always operated as mentioned above, the main blower 38 is continuously operated while one change between the deceleration control and the normal control is being performed.
  • the section blower controlling section 39 removes the deposited rejection material 81 by switching the control between the normal control and the deceleration control according to an amount of the rejection material 81 deposited on the filter member 33. A specific explanation is given below.
  • the section blower controlling section 39 determines the amount of the rejection material 81 deposited on the filter member 33 based on a detection value indicative of the pressure detected by the pressure detecting section 35. Specifically, the section blower controlling section 39 judges whether the detection value obtained in the pressure detecting section 35 is higher than a predetermined threshold (S101 of FIG. 7 ).
  • the section blower controlling section 39 Upon judging that the detection value obtained in the pressure detecting section 35 is higher than the predetermined threshold, the section blower controlling section 39 checks whether the other section blowers 32 are under the deceleration control (S102). Upon checking that none of the other section blowers 32 is under the deceleration control, the section blower controlling section 39 turns off an electric power supply to the corresponding section blower driving section 32b (that is, stops supply of the electric power to the corresponding section blower driving section 32b) (S103, start of the deceleration control).
  • a load on the main blower 38 increases when one section blower 32 is under the deceleration control. Accordingly, when the deceleration control is simultaneously performed in a plurality of the section blowers 32, the rejection material 81 may not be removed from the filter member 33. Accordingly, when the other section blowers 32 are under the deceleration control, the section blower controlling section 39 starts the deceleration control in the next section blower 32 at a timing at which the deceleration control in all the other section blowers 32 is completed (in other words, at a timing at which none of all the section blowers 32 is under the deceleration control) (the process in above-mentioned S102).
  • the section blower controlling section 39 counts an elapsed time from the start of the deceleration control.
  • the section blower controlling section 39 judges whether the elapsed time exceeds a predetermined time (S104).
  • the section blower controlling section 39 turns on the electric power supply to the corresponding section blower driving section 32b (that is, restarts the supply of the electric power to the corresponding section blower driving section 32b), (S105, end of the deceleration control).
  • S104 start of the deceleration control.
  • the predetermined time is set shorter than the time necessary for the rotation of the blades 32a of the section blower 32 to stop. Accordingly, the blades 32a can be prevented from completely stopping. As a result, because the suction force of the section blower 32 does not become zero, the load on the main blower 38 can be reduced.
  • the pressure detecting section 35 is arranged in a region that is inside the suction pipe 91. In this region, the suction current 82 of at least the section blower 32 acts.
  • the rejection material 81 deposits on the filter member 33, as shown in FIG. 5 , the mesh of the filter member 33 is blocked by the rejection material 81.
  • the suction current 82 generated by the section blower 32 it is difficult for the suction current 82 generated by the section blower 32 to flow in the section duct 31. Accordingly, the negative pressure inside the section duct 31 and inside the suction pipe 91 decreases. An decrease of the negative pressure means a change of the pressure in the positive direction.
  • the section blower controlling section 39 judges whether the negative pressure detected by the pressure detecting section 35 is lower than a predetermined threshold. Upon judging that the negative pressure detected by the pressure detecting section 35 is lower than the predetermined threshold, the section blower controlling section 39 performs the deceleration control.
  • the pressure detecting section 35 is arranged in one of the plurality of the suction pipes 91; however, it is allowable to arrange the pressure detecting section 35 in each of the plurality of the suction pipes 91.
  • the pressure detecting section 35 is arranged between the filter member 33 and the section blower 32. Moreover, the pressure detecting section 35 can be arranged in the section duct 31, the suction pipe 91, and the like. The number and the installation locations of the pressure detecting sections 35 can be different in each of the sections. The pressure detecting section 35 may also be omitted in a certain section.
  • the pressure detecting section 35 can be arranged in an exhaust channel arranged downstream of the swirling current generating chamber of the spinning device 9. That is, the pressure detecting section 35 can be arranged upstream of the suction pipe 91.
  • a second variation of the present embodiment is explained below while referring to FIG. 9 .
  • the timing of starting the deceleration control is determined based on a detection result obtained in the pressure detecting section 35.
  • the deceleration control is performed at a preset schedule.
  • FIG. 9 An example of such a schedule is shown in FIG. 9 .
  • the spinning frame 1 has ten sections, and one deceleration control is performed in each of the sections for five seconds and the deceleration control is repeated after one hour while changing the sections.
  • the schedule is set so that the timing of performing the deceleration control in each of the sections is different.
  • the control performed by the section blower controlling section 39 can be simplified by determining the start timing of the deceleration control with the method explained in the second variation.
  • the schedule of the deceleration control can be set based on desired values input by an operator by using a not-shown setting section and the like, or can be set as default in the spinning frame 1.

  • the suction force in the section duct 31 can be reduced by performing the deceleration control of reducing the rotational speed of the blades 32a of the section blower 32. While this deceleration control is being performed, the rejection material 81 deposited on the filter member 33 can be removed easily by using the suction current 83 generated by the main blower 38. Moreover, the load on the main blower 38 can be suppressed because the rotation of the blades 32a of the section blower 32 is not completely stopped.
  • the section blower controlling section 39 of the spinning frame 1 can perform the normal control of rotating the blades 32a of the section blower 32 in the predetermined speed range.

Moreover, it is allowable to reduce the rotational speed of the blades 32a in steps or along a curve instead of linearly reducing the rotational speed as shown in FIG. 4 . As long as the rotational speed of the blades 32a for the deceleration control is lower than the rotational speed for the normal control, the rotational speed of the blades 32a for the deceleration control can be set to a desired speed other than zero.
  • an arrangement is made so that the deceleration control is not performed simultaneously in a plurality of the section blowers 32. That is, the deceleration control in one of the section blowers 32 is started after a state in which the normal control is performed in all the section blowers 32. However, it is allowable to perform the deceleration control simultaneously in a plurality of the section blowers 32 by determining whether to start the deceleration control for each of the sections and the like.
  • a timing of ending the deceleration control (that is, the timing of turning on the electric power supply to the section blower driving section 32b) is determined based on the elapsed time.
  • the timing of ending the deceleration control can be determined based on the negative pressure detected by the pressure detecting section 35 (that is, based on the amount of the rejection material 81 deposited on the filter member 33).
  • the number of the spinning units 2 connected to one section duct 31 is not limited to 20. That is, any number of the spinning units 2 between 1 and 20, or 21 or more can be connected to one section duct 31.
  • the location and the orientation of the filter member 33 are not particularly limited. For example, it is allowable to arrange the filter member 33 in an inclined manner, like in Japanese Patent Application Laid-Open No. 2012-132112 , so that it approaches toward the opening 36 as one goes downstream.
  • a suction pipe through which fly-waste stuck to a drafting roller of the drafting device 7 is transported after sucking can be connected to the section duct 31.
  • a suction port that sucks the yarn waste and the like can be arranged downstream of the spinning device 9.
  • a suction pipe having such a suction port can be connected to the section duct 31.
  • a pipe that sucks and transports the yarn waste generated during the yarn joining and the like can be connected to the section duct 31.
  • the yarn accumulating device 12 pulls the spun yarn 10 from the spinning device 9; however, the invention is not limited to this configuration.
  • the spun yarn 10 can be pulled from the spinning device 9 by using a delivery roller and a nip roller, thereafter, the spun yarn 10 can be accumulated by using the yarn accumulating device 12 or a slack tube provided downstream.
  • the yarn accumulating device 12 can be omitted.
  • the application of the present invention is not limited to the spinning frame explained above. That is, the present invention can be applied, for example, to an open-end spinning frame, an automatic winder, a twisting frame, a doubling machine, and the like.
  • the present invention can be applied to a configuration for removing the yarn waste occurring during the yarn joining.
  • a yarn winding machine includes a plurality of winding units, a section duct, a section suction device, a filter member, a main duct, and a main suction device, and a controlling section.
  • Rejection material generated in at least one of the winding units flows through the section duct.
  • the section suction device has a rotating blade and generates a suction current in the section duct for sucking the rejection material from the winding unit.
  • the filter member is arranged between the section duct and the section suction device.
  • the main duct is connected to the section duct and the rejection material from the section duct flows through it.
  • the main suction device generates a suction current in the main duct for moving the rejection material from the section duct.
  • the controlling section performs, when the main suction device is generating the suction current, a deceleration control of temporarily reducing a rotational speed of the blade while maintaining the rotating state of the blade.
  • the suction force in the section duct can be reduced by performing the deceleration control of reducing the rotational speed of the blade of the section suction device. While this deceleration control is being performed, the rejection material deposited on the filter member can be removed easily by using the suction current generated by the main suction device. Moreover, the load on the main suction device can be reduced because the rotation of the blade of the section suction device is not completely stopped.
  • the above yarn winding machine further includes an accumulation chamber that is connected to an end of the main duct for accumulating the rejection material that flows through the main duct.
  • controlling section maintains a rotating state of a blade of the main suction device during a yarn winding operation.
  • the section suction device can be downsized.
  • the rejection material in the section duct can be moved to the main duct through the opening by the action of the suction current in the main duct.
  • the opening is preferable to arrange the opening in a downstream end of the section duct.
  • the rejection material can be moved to the main duct smoothly via the opening.
  • the controlling section is capable of performing a normal control of rotating the blade of the section suction device in a predetermined speed range, and the controlling section starts the deceleration control after completion of the normal control.
  • the controlling section can send the rejection material, which is deposited by performing the normal control, to the main duct by performing the deceleration control.
  • the controlling section increases, after completion of the deceleration control, the rotational speed of the blade of the section suction device until the rotational speed falls in the predetermined speed range for the normal control.
  • the controlling section can recover the rotational speed of the blade, which was reduced during the deceleration control, to the predetermined speed range for the normal control.
  • the section suction device includes a section driving section that generates a power to rotate the blade thereof, and the controlling section performs the deceleration control by turning off an electric power of the section driving section.
  • the deceleration control can be performed easily on the rotational speed of the blade of the section suction device.
  • the controlling section turns on the electric power of the section driving section before the rotation of the blade of the section suction device stops.
  • the above yarn winding machine includes a pressure detecting section that detects a pressure ( a negative pressure) in at least a region in which the suction current generated by the section suction device acts, and in which the controlling section starts the deceleration control when the pressure detected by the pressure detecting section falls outside of a predetermined range.
  • the deceleration control can be started at an appropriate timing.
  • the pressure detecting section is arranged between the filter member and the section suction device.
  • the deceleration control can be started according to the amount of the rejection material deposited on the filter member.
  • the pressure detecting section at least one among in the winding unit, in the section duct, and in between the winding unit and the section duct.
  • the deceleration control can be started according to the amount of the rejection material deposited on the filter member.
  • the controlling section starts the deceleration control at a preset timing.
  • the deceleration control can be started with a simple control.
  • the controlling section starts the deceleration control in one among the section suction devices at a timing at which the deceleration control is not being performed in any of all the section suction devices.
  • the load on the main suction device increases when the deceleration control is performed on one section suction device, the load on the main suction device can be reduced by shifting the start timing of the deceleration control in each of the section suction devices.
  • the winding unit winds a yarn during at least the period in which the deceleration control is being performed in the section suction device.
  • the yarn winding machine can be operated effectively as the yarn can be wound while the deceleration control is being performed.
  • the yarn winding machine further includes an exhaust duct arranged for each of the section ducts and having an outlet for exhausting to outside the suction current that has passed through the filter member.
  • the filter member is arranged at a connecting part of the section duct and the exhaust duct, and the section suction device is arranged in the exhaust duct but between the filter member and the outlet.
  • the suction current generated by the section suction device can be caused to effectively act in the section duct.
