Connect yarn chassis 3 and move to the cut spinning unit 2 of spinning yarn Y, and in this spinning unit 2, connect the yarn action.Connect yarn chassis 3 and have splicer (connecing yarn feeding device) 26, suction tube 27, suction nozzle 28.Suction tube 27 can be supported rotationally by fulcrum 31, is used for the yarn ends of the spinning yarn Y of spinning apparatus 7 sides is attracted to catch and guide to splicer 26.Suction nozzle 28 can be supported rotationally by fulcrum 32, is used for yarn ends to the spinning yarn Y of coiler device 12 sides and sucks and catch and guide to splicer 26.The yarn ends that 26 pairs of guiding of splicer come connects yarn each other.
Below, above-mentioned yarn held stay the formation of device 50 to describe.As shown in Figures 2 and 3, yarn holds and stays device 50 to have yarn to hold and stay roller 51, electro-motor (CD-ROM drive motor) 55, lower limit side yarn to hold allowance sensor 56, upper limit side yarn to hold allowance sensor 57, yarn hook parts 61, yarn and break away from parts 64, attract mechanism 65, limiting part 71.Hold at spinning apparatus 7 and yarn and to stay between the roller 51, be provided with in order the first guide member 78, yarn action control parts 75 from upstream side.Hold to stay at yarn and be provided with the second guide member 79 between roller 51 and the coiler device 12.
Yarn holds on the driving shaft that stays roller 51 to be fixed on electro-motor 55, rotates by electro-motor 55.Yarn holds and stays roller 51 to have: yarn reserving portion 52, base end side tapering 53, front tapering 54.Yarn reserving portion 52 is the parts cylindraceous of reeling for spinning yarn Y, and it attenuates slightly towards front.Base end side tapering 53 begins the base end part 52a of side towards the terminal chap of upstream side from the coiling of yarn reserving portion 52.Front tapering 54 is from leading section 52b terminal chap towards the downstream of yarn reserving portion 52.
Base end side tapering 53 is accepted to hold from upstream side to yarn and is stayed spinning yarn Y that roller 51 imports and it is guided to the base end part 52a of yarn reserving portion 52 swimmingly.Thus, on yarn reserving portion 52, from the base end side distolateral spinning yarn Y that fitly reels forward.Holding from yarn when staying roller 51 unwinding spinning yarn Y, front tapering 54 can be in disposable the coming off of spinning yarn Y that prevents from being wound on the yarn reserving portion 52, with spinning yarn Y from yarn hold stay roller 51 downstream side derive swimmingly.
It is to detect yarn in non-contacting mode to hold and stay the sensor that has or not spinning yarn Y on the roller 51 that lower limit side yarn holds allowance sensor 56, and this sensor is configured in yarn in the mode relative with yarn reserving portion 52 and holds the rear side that stays roller 51.Lower limit side yarn holds allowance sensor 56 and holds holding in the situation that allowance reaches lower limit amount of the spinning yarn Y that stays on the roller 51 being wound in yarn, lower limit is held the allowance detection signal send to cell controller 10.It is to detect yarn in non-contacting mode to hold and stay the sensor that has or not spinning yarn Y on the roller 51 that upper limit side yarn holds allowance sensor 57, and this sensor is configured in yarn in the mode relative with the leading section 52b of yarn reserving portion 52 and holds the side of staying roller 51.Upper limit side yarn holds allowance sensor 57 and holds holding in the situation that allowance reaches upper limit amount of the spinning yarn Y that stays on the roller 51 being wound in yarn, the upper limit is held the allowance detection signal send to cell controller 10.
It is parts that spinning yarn Y is broken away from from yarn hook parts 61 that yarn breaks away from parts 64, and it is configured in yarn and holds near the front tapering 54 of staying roller 51.Yarn breaks away from parts 64 and is supported in the mode that can swing between down position and lifting position.Down position is the position of keeping out of the way from the yarn road.Lifting position is the spinning yarn Y on the yarn road is boosted and to make spinning yarn Y from position that yarn hook parts 61 break away from.Yarn breaks away from parts 64 and is suppressed to the decline position side by spring (diagram is omitted).Therefore, yarn breaks away from parts 64 and usually is in down position, when connecing the yarn action etc., moves to lifting position by being located at the pneumatic cylinder (diagram is omitted) that connects on the yarn chassis 3.
Limiting part 71 (with yarn reserving portion 52 relatively) be configured in yarn and hold the side of staying roller 51.Limiting part 71 has the first restriction section 72, the second restriction section 73 and the 3rd restriction section 74.Yarn when the first restriction section 72 is arranged in the coiling of spinning yarn Y holds the upstream side of the attraction mouth 66a of the direction of rotation of staying roller 51.The second restriction section 73 is arranged in the downstream of the attraction mouth 66a of this direction of rotation.The first restriction section 72 and the second restriction section 73 and the base end part 52a of yarn reserving portion 52 relatively configure.In the situation that spinning yarn Y cuts off in spinning apparatus 7 sides, limit to the movement of the leading section 52b side of yarn reserving portion 52 from the unwinding of the leading section 52b side of yarn reserving portion 52 prior to spinning yarn Y in the yarn ends of the spinning yarn Y of the base end part 52a of yarn reserving portion 52 side oscillation by 73 pairs in the first restriction section 72 and the second restriction section.The 3rd restriction section 74 relatively configures with yarn reserving portion 52, at spinning yarn Y in the cut situation of coiler device 12 sides, by 74 pairs in the 3rd restriction section in the yarn ends of the spinning yarn Y of the leading section 52b of yarn reserving portion 52 side oscillation prior to spinning yarn Y from the unwinding of the base end part 52a side of yarn reserving portion 52 and limit to the movement of the base end part 52a side of yarn reserving portion 52.Upper limit side yarn holds the bottom that allowance sensor 57 is installed in limiting part 71.
Yarn action control parts 75 are mounted in the sheet material that yarn holds the upstream side (being the lower surface of tension pick-up 9 (end face in downstream) here) that stays roller 51, and it has guiding function section 76, limitation function section 77.76 couples of spinning yarn Y of guiding function section give tension force and spinning yarn Y-direction yarn are held the base end side tapering 53 of staying roller 51 and guide.And guiding function section 76 prevents from transmitting from spinning apparatus 7 the twisted downstream transmission to guiding function section 76 of the spinning yarn Y that comes.Limitation function section 77 prevents from breaking away from the yarn ends of spinning yarn Y spinning yarn Y in the cut situation of spinning apparatus 7 sides is held the spinning yarn Y that stays device 50 from being directed to yarn yarn road and holds the situation of staying device 50 side shiftings to yarn.
The first guide member 78 is mounted in the sheet material that yarn holds the upstream side (being the lower surface of tension pick-up 9 (end face in downstream) here) that stays roller 51, spinning yarn Y is guided to the detection position that is configured in the regulation in the framework for the slit on the framework that is formed on tension pick-up 9.The second guide member 79 is mounted in the sheet material that yarn holds the downstream (referring on the module frame 81 of yarn treatment module 80) of staying roller 51 here.The second guide member 79 is used for spinning yarn Y is guided to the assigned position of waxing attachment 11, thereby and the track of the spinning yarn Y that swings of yarn hook parts 61 restrictions by rotation make the movement of spinning yarn Y in downstream of the second guide member 79 stable.
Below, illustrate that above-mentioned yarn holds the action of staying device 50.In spinning unit 2, in the situation of the common action that generates spinning yarn Y and reel to package P, electro-motor 55 holds yarn to stay roller 51 to drive with the rotary speed of constant.Thus, yarn hook parts 61 hold with yarn and stay roller 51 to rotate integratedly, flier 63 hook spinning yarn Y.At hook the yarn hook parts 61 that rotate under the state of spinning yarn Y yarn that spinning yarn Y is wound on rotation hold and stay on the roller 51.
Hold at yarn and to stay on the roller 51 behind the coiling spinning yarn Y, cell controller 10 holds the allowance detection signal and holds the upper limit that allowance sensor 57 sends from upper limit side yarn and hold the action of allowance detection signal control spinning unit 2 based on hold lower limit that allowance sensor 56 sends from lower limit side yarn, is that lower limit amount is above and below the upper limit amount so that be wound on the allowance of holding that yarn holds the spinning yarn Y that stays on the roller 51.When the allowance of holding that is wound on yarn and holds the spinning yarn Y that stays on the roller 51 is that lower limit amount is when above, the contact area that yarn holds the yarn reserving portion 52 that stays roller 51 and spinning yarn Y increases, and can skid hardly between yarn reserving portion 52 and spinning yarn Y etc.Therefore, yarn holds and stays device 50 to hold the rotation of staying roller 51 from the spinning apparatus 7 stable spinning yarn Y that draw (that is, with constant quality and constant speed) by yarn.
Hold at yarn and to stay roller 51 to be wound with under the state of spinning yarn Y, if the tension force of the spinning yarn Y of coiler device 12 sides increases, then wanting to make yarn hook parts 61 to hold with respect to yarn stays roller 51 to carry out counterrotating power (that is the power of, wanting to make the rotation of yarn hook parts 61 to stop) to act on the flier 63.Thus, when the torque that produces on the yarn hook parts 61 is setting when above, yarn hook parts 61 hold with respect to yarn and stay roller 51 relatively to rotate.Its result is that spinning yarn Y holds from yarn and stays roller 51 unwindings.If the tension force of the spinning yarn Y of coiler device 12 sides reduces, the not enough setting of the torque that produces on the yarn hook parts 61, then yarn hook parts 61 hold with yarn and stay the rotation of roller 51 one.Its result is to hold at yarn and stay coiling spinning yarn Y on the roller 51.Like this, yarn holds and stays device 50 to regulate to prevent that the tension change of the spinning yarn Y of coiler device 12 sides is passed to spinning apparatus 7 sides to the tension force of the spinning yarn Y of coiler device 12 sides.
Below, the action of the spinning unit 2 when the yarn defect is detected describes.In spinning unit 2, when the common action that generates spinning yarn Y and reel to package P, if yarn clearer 8 detects the yarn defects, then yarn clearer 8 sends to cell controller 10 with yarn defect detection signal.After cell controller 10 receives yarn defect detection signal, the action of drafting system 6 and spinning apparatus 7 etc. is stopped.Thus, no longer to fiber bundle F twisting, spinning yarn Y is cut off in spinning apparatus 7 sides.
Even spinning yarn Y is cut off in spinning apparatus 7 sides, the rotation that cell controller 10 also makes yarn hold and stays roller 51 reaches the coiling continuation of being undertaken by coiler device 12.Therefore, as shown in Figure 4, the yarn ends of cut spinning yarn Y is wound onto yarn and holds and stay on the roller 51, and spinning yarn Y from yarn hold stay roller 51 to coiler device 12 side unspooling operations in the base end part 52a of yarn reserving portion 52 side oscillation.At this moment, this yarn ends is limited the first restriction section 72 restrictions of parts 71 to the movement of the leading section 52b side of yarn reserving portion 52, simultaneously, is subject to attracting the effect of the attraction stream that produces among mouthful 66a.Therefore, spinning yarn Y holds from yarn swimmingly and stays roller 51 to coiler device 12 side unwindings.And by unspooling operation, the Soft flocks of the yarn ends of upstream side are not removed by attraction mechanism 65 with almost dispersing at spinning yarn Y.
When coiler device 12 was wound up into the yarn ends of cut spinning yarn Y to package P, the control signal that cell controller 10 will illustrate the spinning unit 2 that spinning yarn Y has been cut off sent to and connects yarn chassis 3.Thus, connecing yarn chassis 3 moves to before this spinning unit 2 and begins to connect the yarn action.
At first, as shown in Figure 5, suction nozzle 28 turns to the near surface of package P and produces and attracts stream, and simultaneously, coiler device 12 makes package P reverse rotation.Thus, suction nozzle 28 draws and catches the yarn ends of spinning yarn Y from the surface of package P.Next, as shown in Figure 6, suction nozzle 28 turns to home position (position of readiness), and the yarn ends of the spinning yarn Y of coiler device 12 sides is guided to splicer 26.Here, coiler device 12 stops the rotation of package P.
On the other hand, as shown in Figure 5, suction tube 27 turns to the downstream of spinning apparatus 7 and produces and attracts stream.At this moment, because cell controller 10 begins the action of drafting system 6 and spinning apparatus 7 etc. again, so the yarn ends of 27 couples of spinning yarn Y that generate of suction tube catches.Next, as shown in Figure 6, suction tube 27 turns to home position (position of readiness), and the yarn ends of the spinning yarn Y of spinning apparatus 7 sides is guided to splicer 26.
After the yarn ends of the spinning yarn Y of the yarn ends of the spinning yarn Y of coiler device 12 sides and spinning apparatus 7 sides is directed to splicer 26, hold at yarn and to stay in the device 50, the spinning yarn Y of yarn hook parts 61 hook spinning apparatus 7 sides, and hold to the yarn of one rotation and to stay coiling spinning yarn Y on the roller 51.Thus, even the coiling that is undertaken by coiler device 12 stops, also can relaxing hardly on the spinning yarn Y that sends from spinning apparatus 7.Like this, thus yarn hold stay device 50 can by connect that yarn chassis 3 carries out connect the yarn action time etc. the spinning yarn Y that sends from spinning apparatus 7 is detained can prevent that spinning yarn Y from occuring lax.
When being wound on yarn and holding holding allowance and arriving lower limit amount of the spinning yarn Y that stays on the roller 51, hold at yarn and can skid hardly between the yarn reserving portion 52 that stays roller 51 and the spinning yarn Y etc.Its result is, spinning yarn Y from spinning apparatus 7 by stably (that is, with the quality of constant and the speed of constant) draw.Cell controller 10 makes yarn break away from parts 64 and moves to lifting position from down position, and yarn breaks away from parts 64 makes spinning yarn Y break away from from yarn hook parts 61.
Like this, yarn hold stay spinning yarn Y is broken away from from yarn hook parts 61 after, almost do not stop spinning yarn Y to hold the resistance that stays roller 51 unwindings from yarn.Thus, before the holding allowance and reach lower limit amount of spinning yarn Y, be wound on yarn and hold the spinning yarn Y (that is, the unsettled spinning yarn Y of quality) that stays on the roller 51 and hold from yarn by suction tube 27 and stay roller 51 unwindings and be inhaled into.In addition, even during spinning yarn Y is attracted pipe 27 and sucks, spinning yarn Y is also stably drawn and is wound on yarn from spinning apparatus 7 and holds and stay on the roller 51, so the allowance of holding of spinning yarn Y maintains more than the lower limit amount.
After removing the unsettled spinning yarn Y of quality by suction tube 27, cell controller 10 makes yarn break away from parts 64 and moves to down position from lifting position.Thus, the spinning yarn Y of spinning apparatus 7 sides is hooked on the yarn hook parts 61, and spinning yarn Y can not hold from yarn and stay downstream side unwinding of roller 51.The yarn ends of the spinning yarn Y of 26 pairs of coiler device 12 sides of splicer is connected the yarn ends of spinning yarn Y of side and is connected with spinning apparatus.At this moment, be removed by suction tube 27 and suction nozzle 28 in the splicer 26 cut yarn ends of not wanting.Undertaken by splicer 26 connect the knot bundle after, cell controller 10 begins the coiling that is undertaken by coiler device 12 again.
Below, the action of the spinning unit 2 during to Yarn break describes.As shown in Figure 7, in the spinning unit 2, when the common action that generates spinning yarn Y and reel to package P, if hold the broken end that spinning yarn Y occurs in the downstream of staying device 50 at yarn, the yarn movable sensor (diagram is omitted) that then holds the downstream of staying device 50 by being located at yarn can't detect spinning yarn Y.Thus, cell controller 10 is judged as to hold to stay between device 50 and the coiler device 12 at yarn Yarn break occurs, and stops immediately the action of drafting system 6 and spinning apparatus 7 etc.Thus, can not twist fiber bundle F, and spinning yarn Y also is cut off in spinning apparatus 7 sides.
Even spinning yarn Y is cut off in spinning apparatus 7 sides, the rotation that cell controller 10 also makes yarn hold and stays roller 51 reaches the coiling continuation of being undertaken by coiler device 12.Therefore, the yarn ends of cut spinning yarn Y is wound onto yarn and holds and stay on the roller 51, and in the base end part 52a of yarn reserving portion 52 side oscillation.The yarn ends of the spinning yarn Y that swings is limited the first restriction section 72 restrictions of parts 71 to the movement of the leading section 52b side of yarn reserving portion 52, simultaneously, be subject to attracting the effect of the attraction stream that produces among mouthful 66a.Therefore, the Soft flocks of the yarn ends of upstream side are attracted mechanism 65 with dispersing hardly and remove.
Be wound on yarn and hold the spinning yarn Y that stays on the roller 51 owing to also disconnecting in the downstream, so, do not hold from yarn and stay downstream side unwinding of roller 51.Therefore, cell controller 10 holds yarn and stays be rotated in the forward (the common direction of rotation) of roller 51 to stop, yarn is held stay roller 51 reverse rotations.At this moment, be wound on yarn ends that yarn holds the upstream side that stays the spinning yarn Y on the roller 51 is limited the second restriction section 73 restrictions from parts 71 to the movement of the leading section 52b side of yarn reserving portion 52.Therefore, as shown in Figure 8, the attraction mouth 66a that the yarn ends of upstream side is attracted mechanism 65 catches reliably.And, be wound on yarn ends that yarn holds the downstream of staying the spinning yarn Y on the roller 51 is limited the 3rd restriction section 74 restrictions from parts 71 to the movement of the base end part 52a side of yarn reserving portion 52.Therefore, be wound on yarn and hold the spinning yarn Y that stays on the roller 51 from the swimmingly unwinding of base end part 52a side of yarn reserving portion 52, and be attracted mechanism 65 and suck.
Hold the spinning yarn Y that stays on the roller 51 by after attracting mechanism 65 to be removed when being wound on yarn, cell controller 10 holds yarn and stays the reverse rotation of roller 51 to stop, yarn is held stay roller 51 to be rotated in the forward.Cell controller 10 will illustrate the spinning unit 2 of broken end has occured spinning yarn Y control signal and send to and connect yarn chassis 3.Thus, before connecing yarn chassis 3 and moving to this spinning unit 2, and carry out as described above and connect the yarn action.
