Abstract

A spinning machine includes a spinning device, a winding device, a yarn accumulating roller, a yarn hooking member, and a yarn removing lever. The yarn accumulating roller winds spun yarn around an outer peripheral surface thereof and rotates with the spun yarn wound around to feed the spun yarn from the spinning device while applying tension to the spun yarn. While being engaged with the spun yarn, the yarn hooking member rotates integrally with the yarn accumulating roller, and thus prevents the spun yarn from being unwound from the outer peripheral surface of the yarn accumulating roller. The yarn removing lever is arranged downstream of the yarn hooking member in a yarn transporting direction, and can be moved between a lowered position where the yarn removing lever does not make contact with the spun yarn and a lifted position where the yarn hooking member makes contact with the spun yarn. At the lifted position, the yarn removing lever removes the spun yarn from the yarn hooking member.

Then, with reference to Fig. 3 and Fig. 4 the detailed formation of yarn storing unit 12 is described.It is the roller members that are made of the material with resistance to abrasion that yarn is deposited roller 21.Yarn is deposited on the motor drive shaft 25a that roller 21 is fixed in electrical motor 25.If the side with yarn guide member 22 of outer peripheral face 21a of yarn being deposited roller 21 is as the top, the side that disposes electrical motor 25 as cardinal extremity, then possessed base end side cone part 21b, cylindrical portion 21c and tip side cone part 21d from cardinal extremity to the top successively.
Cylindrical portion 21c constitutes the slightly thin shape of tip side, does not have ladder difference ground continuous shape for cone part 21b, the 21d of relative both sides simultaneously.The size of cylindrical portion 21c suitably is decided to be the spun yarn 10 that can accumulate at least more than the minimum amount of storage of above-mentioned necessity.Above-mentioned yarn amount of storage sensor 27 and this cylindrical portion 21c are in opposite directions.Yarn amount of storage sensor 27 detects and is rolled onto the amount of storage that yarn is deposited the yarn on the roller 21, and with the cell controller that sends to of detected yarn amount of storage.
It is the mild coniform of larger diameter side that base end side cone part 21b and tip side cone part 21d are constituted as the end face side respectively.Deposit among the outer peripheral face 21a of roller 21 at yarn, base end side cone part 21b is constituted as by making the spun yarn 10 supplied with successfully move and make its cylindrical portion 21c in the middle of arriving spun yarn 10 fitly is rolled onto the surface of cylindrical portion 21c to small diameter portion from the major diameter part.In addition, tip side cone part 21d has the function of the jumping through hoops phenomenon that the spun yarn 10 on Xie Shushi prevents to roll up comes off for the moment, thereby also has simultaneously in order to carry successively and warp spun yarn 10 guarantees the function of drawing smoothly of spun yarns 10 to the major diameter part of end face side from small diameter portion.
As shown in Figures 3 and 4, the yarn guide member 22 of depositing the tip side configuration of roller 21 at yarn is configured to that to deposit roller 21 concentric with above-mentioned yarn.Yarn guide member 22 possesses ingot axle (flyer axis) 33 and is fixed in the flier 38 on its top.
Yarn is deposited roller 21 and is supported ingot axle 33 with the relative rotation relatively.On the other hand, deposit mounting permanent magnet on any one party of roller 21 at ingot axle 33 or yarn, and magnetic hysteresis part (hysteresis) is installed on the opposing party.Under the effect of these magnetic mechanisms, antagonism yarn guide member 22 relative yarns take place deposit the resistance torque of roller 21 rotations.Under the effect of this resistance torque, yarn guide member 22 tracking yarns are deposited the rotation of roller 21 and are rotated, but consequently the two one rotation.On the other hand, applying to yarn guide member 22 under the situation of the power that overcomes this resistance torque, yarn guide member 22 relative yarns are deposited roller 21 and are relatively rotated.
Above-mentioned flier 38 constitutes suitably that to deposit the outer peripheral face 21a of roller 21 to above-mentioned yarn crooked and then can engage the shape of (hook spun yarn 10) with spun yarn 10.Not with reel for yarn under yarn is deposited state on the roller 21, if flier 38 is deposited the rotation of roller 21 one with yarn, then this flier 38 engages with spun yarn 10.The spun yarn 10 that engages with the flier 38 of this rotation dangled by this flier 38 so that to the yarn of rotation deposit roller 21 outer peripheral face guiding, reel.
Below deposit the situation of the spun yarn 10 on the roller 21 and describe twisting in yarn.That is, to the spun yarn 10 of outer peripheral face 21a guiding, on cylindrical portion 21c, reeled many times by upstream side guide rail 23 from base end side.Then, the spun yarn 10 of drawing from the tip side of outer peripheral face 21a is sent to the downstream by after the flier 38 by downstream guide rail 26.
As shown in Figure 4, deposit under the state on the roller 21 spun yarn 10 being rolled onto yarn, if apply the power of the spun yarn 10 that side tractive downstream engages with flier 38, then apply and be used for depositing the power that makes yarn guide member 22 rotations that the top ends of roller 21 is separated the spun yarn 10 that relaxes from yarn to flier 38.Thereby, the yarn tension in the downstream of yarn storing unit 12 (yarn tension between yarn storing unit 12 and the wind2 13) is the size that can overcome above-mentioned resistance torque, then yarn guide member 22 is deposited roller 21 with yarn and can be rotated independently more, thereby spun yarn 10 is separated easypro from the tip side that yarn is deposited roller 21 by flier 38 lentamente.
On the contrary, the yarn tension in the downstream of yarn storing unit 12 is not enough to overcome under the situation of above-mentioned resistance torque, and yarn guide member 22 is deposited the rotation of roller 21 one with yarn.In this case, yarn guide member 22 plays the tip side that stops spun yarn 10 to deposit roller 21 from the yarn of rotation and separates easypro effect.
Like this, yarn storing unit 12 can utilize when the tension force of the yarn in downstream improves and separate the easypro action of separating of relaxing yarn and stoping yarn when the tension force of yarn reduces (it is lax that yarn will become), eliminates the lax of yarn and gives suitable tension force.In addition, yarn guide member 22 can also utilize the action of the change that absorbs the tension force that the spun yarn 10 between yarn storing unit 12 and wind2 13 applies as above above-mentionedly, the influence of change that prevents this tension force to from spinning apparatus 9 to the spun yarn 10 the yarn storing unit 12.Can utilize the yarn storing unit 12 of above formation to draw spun yarn 10 from spinning apparatus 9 with more stable speed.
In addition, because yarn is deposited roller 21 by the speed drive rotation with regulation, so spun yarn 10 is rolled onto the base end side that this yarn is deposited roller 21 with specified speed.Thereby the tip side of depositing roller 21 from yarn at spun yarn 10 is separated easypro velocity ratio and is rolled onto under the fireballing situation of base end side, and the yarn amount of storage reduces, and does not separate from tip side under the easypro situation at spun yarn 10, and the yarn amount of storage increases lentamente.
In addition, yarn storing unit 12 possesses the line of separating bar 28 as mentioned above.As shown in Figure 4, this separates the parts that line bar 28 is formed the approximate L font of the elongated portion (service portion 28a) with horizontal arrangement.Separate the base portion of line bar 28 and supported by axis of rocking 28b, this separates that line bar 28 is constituted as can above-mentioned axis of rocking 28b be that the center fluctuates between hoisting position and lowering position.When separating line bar 28 and be positioned at lowering position (the 1st position, transferring position, position for example shown in Figure 2), separate line bar 28 and be not constituted as and contact with the yarn road of spun yarn 10.On the contrary, when separating line bar 28 and be positioned at hoisting position (the 2nd position, in-position, position for example shown in Figure 5),, above-mentioned service portion 28a unties spun yarn 10 from flier 38 thereby promoting the yarn road of spun yarn 10.This is separated line bar 28 and is maintained at lowering position by the spring members reinforcing of utilization figure summary usually the time.Because the air cylinder 49 that joint chassis 3 possesses shakes, separate line bar 28 and be raised arm 47 promotions and move to hoisting position.
In above formation, can separate line bar 28 and move to hoisting position and come to untie spun yarn 10 by making from separating line parts 22.Like this, the tip side of depositing roller 21 from yarn is separated resistance when relaxing spun yarn 10 (resistance torque that applies to yarn guide member 22) and is not acted on yarn.Consequently, even deposit at yarn under the situation a little less than the yarn tension in downstream of roller 21, also can deposit roller 21 and separate easypro yarn from this yarn.Do not deposit to make under the state on the roller 21 and separate line bar 28 and rise if be rolled onto yarn, then can stop flier 38 to engage, so the controlled spun yarn 10 of making is not wound to yarn and deposits on the roller 21 with spun yarn 10 at yarn.
But, utilize above-mentioned yarn to deposit the transportation of the spun yarn 10 of roller 21 (from drawing of spinning apparatus 9) for stable, must often maintain the state that yarn is deposited a certain amount of above (being more than the necessary minimum amount of storage) spun yarn 10 of volume on the roller 21.Therefore, be used in the present embodiment control arm 71 from the signal feedback of yarn amount of storage sensor 27.Specific as follows described.
At first, to the tension force that the yarn (spun yarn 10 between yarn storing unit 12 and the wind2 13) that hangs on the yarn guide member 22 applies, deposit the line sending speed (from the speed that spins of spinning apparatus 9) of roller 21 and the winding speed decision of wind2 13 by yarn basically.That is, winding speed is more fast than line sending speed, and then the tension force that applies to yarn becomes big more, thereby yarn is deposited roller 21 from yarn lentamente and separated easypro.On the contrary, winding speed is more slow than line sending speed, and then the tension force that applies to yarn becomes more little, and the amount of storage that yarn is deposited the yarn on the roller 21 increases lentamente.Because yarn is deposited the rotative speed (spinning speed) of roller 21 and is generally necessarily, mainly changes because of the winding speed of wind2 13 so hang over the tension force of the yarn on the yarn guide member 22.
When usually reeling, in order to give suitable winding tension to spun yarn 10, it is some soon to set the rotative speed of reel 72 for line sending speed (speed that spins of spinning apparatus 9) that winding speed deposits roller 21 than yarn.Thereby, be wound to yarn deposit spun yarn 10 on the roller 21 separated lentamente easypro, thereby the amount of storage of yarn reduces.
If the amount of storage that yarn amount of storage sensor 27 detects yarn becomes less than the minimum amount of storage of necessity, then thereby the cell controller of this spinning unit 2 drives and schemes mobile cylinder (shiftcylinder) slightly be controlled to arm 71 is rotated to the left side of Fig. 2, and then separates packages 45 from reel 72.Like this, so although continue the inertia rotation because package 45 loses propulsive effort, its winding speed reduces lentamente.Thereby the amount of storage that yarn is deposited the yarn of roller 21 increases lentamente.
But, if deposit on the roller 21 above being wound to yarn to the spun yarn 10 of the amount that cylindrical portion 21c deposits, then this spun yarn 10 is rolled onto yarn and deposits the position of roller 21 coil diameter greatly changes by rising to base end side cone part 21b, thereby can not draw spun yarn 10 from spinning apparatus 9 with correct speed.Therefore, yarn storing unit 12 becomes more than the specified value for the amount of storage of utilizing yarn amount of storage sensor 27 to detect spun yarn 10.Become more than the specified value if detect the amount of storage of spun yarn 10, then the said units controller makes arm 71 rotate to the right side of Fig. 2, thereby package 45 is contacted with reel 72.Like this, because winding speed recovers, therefore spun yarn 10 is deposited roller 21 and is separated easypro from yarn as mentioned above.
Like this, thus can be by utilizing mobile cylinder that arm 71 is shaken to make package 45 relative reels 72 contacts or sowing discord the winding speed of regulating wind2 13.Can deposit the yarn amount of storage of roller 21 and feed back and carry out simultaneously the control of the winding speed of wind2 13 by detecting yarn, often keep and the spun yarn 10 more than the minimum amount of storage of necessity is deposited in yarn deposit state on the roller 21.
Then, with reference to Fig. 5～Figure 10, the Yarn processing method during to the joint in the spinning frame 1 of present embodiment describes.Wherein, in the diagram of curves of Figure 10 the longitudinal axis for from the haul-off tension of the yarn of spinning apparatus 9 and the amount of storage that yarn is deposited the yarn on the roller, mark resultant yarn line tension and yarn amount of storage among the figure.In addition, transverse axis is the time.And then in the diagram of curves of Figure 10, what represent with solid line is the amount of storage (yarn amount of storage) that yarn is deposited the yarn on the roller, and what dot is haul-off tension (yarn tension) from the yarn of spinning apparatus.
At first, if yarn clearer 52 detects yarn faults in the coiling of spun yarn 10, then this yarn clearer 52 sends the yarn faults detecting signal to cell controller.If receive above-mentioned yarn faults detecting signal, then the said units controller uses cutter (cutter) 57 to cut off spun yarn 10 immediately, and then draw gear 7 or spinning apparatus 9 etc. are stopped.At this moment, the yarn in the downstream of above-mentioned off-position temporarily is wound in the package 45 by wind2 13.Like this, be rolled onto the spun yarn 10 that yarn deposits on the roller 21 and be wound in the package 45 yet, this yarn is deposited on the roller 21 does not have yarn.In addition, the part that contains above-mentioned yarn faults also temporarily is wound in the package 45.
In addition, if receive above-mentioned yarn faults detecting signal, then cell controller switches to the supervision of the yarn faults of interim interruption yarn clearer 52.
Then, cell controller carries control signals to make before it marches to this spinning unit 2 to joint chassis 3, makes joint action beginning.At first, cell controller makes suction nozzle 46 turn to the near surface (with reference to Fig. 5) of package 45, makes to attract stream that wind2 13 contrarotation packages 45 take place to utilize simultaneously.Like this, draw yarn ends (yarn under working), attracted to catch by suction nozzle 46 from the outer peripheral face of package 45.In addition, can come to remove the yarn that contains above-mentioned yarn faults from package 45 this moment by drawing the yarn that contains above-mentioned yarn faults from package 45 and then being held by suction nozzle 46.
Then, make package 45 contrarotation limits attract under the state of yarn under working suction nozzle 46 to be rotated upward on the limit, and then to splicer 43 guiding these yarn under working (with reference to Fig. 6).If yarn under working is directed to splicer 43, the rotation of package 45 is stopped.
In addition, before and after the rotational action of said suction nozzle 46, cell controller makes suction pipe 44 turn near the downstream (with reference to Fig. 5) of spinning apparatus 9.Then, 9 grades are restarted spinning unit thereby cell controller drives spinning apparatus once more, thereby attract stream that the yarn ends (going up yarn) (yarn seizure operation) of spinning apparatus 9 sides takes place to catch simultaneously in suction pipe 44.The yarn tension of this moment and yarn amount of storage are represented constantly with the A of the diagram of curves of Figure 10.As shown in figure 10, only attract yarn under the effect in the attractive force of suction pipe 44 constantly at this A, so yarn tension is low, the yarn amount of storage is zero in addition.
Then, draw spun yarn 10 on one side to splicer 43 guiding by proceeding to attract also to make simultaneously suction pipe 44 to rotate on one side downwards from spinning apparatus 9.At this moment, as shown in Figure 6, cell controller drives air cylinder 49 to approaching side and makes and separate line bar 28 and move to hoisting position.Thus, spun yarn 10 can not engage with the flier 38 of rotation, and yarn ends is directed to splicer 43.
Make the reason of separating 28 risings of line bar as follows.That is, the attractive force of suction pipe 44 does not have strong to the resistance torque that can overcome yarn guide member 22.Thereby the attractive force that can not utilize suction pipe 44 is deposited roller 21 from yarn and is separated the spun yarn 10 that relaxes by yarn guide member 22.Therefore, if deposit roller 21 coiling yarns to yarn finishing before splicer 43 guiding yarn ends beginning, then suction pipe 44 can not be than yarn on its bigger ground tractive, thus can not guide to splicer 43 with going up yarn, thus joint is failed.Therefore, by separating line bar 28 and rise and prevent that spun yarn 10 beginnings from depositing roller 21 to yarn and reeling finishing before splicer 43 guiding suction pipes 44, to make.
Fig. 5 and Fig. 6 have described suction pipe 44 and have carried out rotational action simultaneously with suction nozzle 46, and rotational action can be for before, also can for after.
If last yarn finishes to the guiding of splicer 43, then make and separate the control that line bar 28 descends apace.Like this, bonded assembly spun yarn 10 engages with flier 38 between spinning apparatus 9 and the suction pipe 44, and spun yarn 10 begins to be rolled onto yarn and deposits (state of Fig. 7, guide operation (yarn guiding operation)) on the roller 21.That is, though the coiling of wind2 13 stops in the joint action, during this period, spun yarn 10 is output continuously from spinning apparatus 9, thus constant if spun yarn 10 is in this state, the lax of yarn then can be taken place.Therefore, deposit on the roller 21, can prevent the lax of spun yarn 10 by spun yarn 10 being rolled onto yarn.The effect of the Yarn relaxation eliminating device when like this, yarn storing unit 12 plays joint.In the diagram of curves of Figure 10, represent constantly that with B this separates the moment that line bar 28 descends.As shown in figure 10, the yarn amount of storage that yarn is deposited on the roller 21 after this moment increases, and the haul-off tension from the spun yarn 10 of spinning apparatus 9 increases (amount of storage increase operation) thereupon
But, as mentioned above, until deposit the spun yarn of depositing on the roller 21 more than the necessary minimum amount of storage 10 at yarn till during, deposit between roller 21 and the spun yarn 10 at yarn and to skid easily, thus from the haul-off tension instability of the yarn of spinning apparatus 9.Thereby, we can say during until deposit the yarn of depositing q.s (necessary minimum amount of storage) on the roller 21 at yarn till (between the BC of Figure 10) that the spun yarn 10 of drawing from spinning apparatus 9 is the unsettled part of yarn qualities.
If spinning machine in the past, then when utilizing suction pipe 44, after this begin the joint between the yarn ends of splicer 43 immediately to splicer 43 guiding yarn ends.But, have unsettled thread segment on the roller 21 owing to depositing as mentioned above, so if carry out joint under this state, then this unsettled thread segment is wound in the package 45 at yarn.
Therefore, be blended in the package 45 in order to prevent this unsettled part, the spinning frame 1 of present embodiment is constituted as described below.
At first, can not begin joint immediately yet, but utilize yarn amount of storage sensor 27 to monitor that the yarn amount of storage that yarn is deposited on the roller 21 judges whether to reach necessary minimum amount of storage even cell controller is guided to splicer 43 at last yarn by suction pipe 44.Under the situation of yarn amount of storage, separate line bar 28 and be in the decline state spun yarn 10 of reeling that remains unchanged by making less than the minimum amount of storage of necessity.If utilize yarn amount of storage sensor 27 to detect the yarn amount of storage minimum amount of storage above (C of Figure 10 constantly) that necessitates, then cell controller utilizes air cylinder 49 to make to separate line bar 28 and moves to hoisting position, thereby unties spun yarn 10 (Fig. 9) from flier 38.In addition, shown in the constantly later part of the C of Figure 10, after the yarn amount of storage necessitates more than the minimum amount of storage, stable and form roughly certain from the haul-off tension of the spun yarn 10 of spinning apparatus 9.
If deposit at yarn under the state of roller 21 rotation and untie spun yarn 10 from flier 38, then since the resistance that stops the top ends of depositing roller 21 from yarn to separate the spun yarn 10 that relaxes disappear, so, also can separate the spun yarn 10 that relaxes even become under the effect of the weak attractive force of suction pipe 44.Thereby under state as shown in Figure 9, thereby yarn is deposited yarn on the roller 21 and is separated to relax and held by suction pipe 44.Like this, can give up to fall yarn by suction pipe 44 and deposit unsettled yarn (yarn is discarded operation) on the roller 21.In addition, when separating the rising of line bar 28, the cooresponding spun yarn 10 of amount lax of roller 21 rotations only takes place to deposit with yarn in the top ends of depositing roller 21 at this yarn, thereby 44 in suction pipe holds this slack.On the other hand, deposit the base end side of roller 21 at yarn, deposit at yarn under the effect of rotation of roller 21, spun yarn 10 is reeled again.That is, because only with the amount that is attracted by suction pipe 44 spun yarn 10 of reeling again, so shown in the part between the CD of Figure 10, the yarn amount of storage that yarn is deposited on the roller 21 is retained as roughly certain.
Thereby, owing on one side keep depositing the state of the above yarn of necessary minimum amount of storage, from spinning apparatus 9 carry out the drawing of spun yarn 10 on one side, be rolled onto the steady quality of spun yarn 10 that yarn is deposited the base end side of roller 21 again so can make.Then, owing to separate the unsettled spun yarn 10 that relaxes in tip side on the contrary, so yarn is deposited the spun yarn 10 that yarn on the roller 21 is replaced as stabilised quality successively from the spun yarn 10 of base end side roll stabilizing.
If separate line bar 28 and rise that to begin separating of unsettled yarn easypro by making, deposit the necessary specified time of yarn that spun yarn 10 on the roller 21 all is replaced as stabilised quality (in other words through yarn then, deposit from yarn and all to give up unsettled spun yarn 10 time necessary of quality on the roller 21), then cell controller utilizes splicer to carry out joint (D of Figure 10 is constantly).Like this can be not the part of residual unstable quality in the spun yarn 10 after joint finishes.
In the above-described embodiment, separate this spun yarn 10 that relaxes by untie spun yarn 10 from flier 38, as long as the attractive force of suction pipe 44 is enough powerful to the resistance torque that overcomes yarn guide member 22,, also can deposits roller 21 and separate the spun yarn 10 that relaxes from yarn even then do not untie spun yarn 10 from flier 38.But, if often overcome the attractive force of the resistance torque of yarn guide member 22, then the loss of energy is big.Consider above point, only separate when relaxing spun yarn 10 (be in the above-described embodiment only make separate line bar 28 move to hoisting position during) depositing roller 21 from yarn, deposit spun yarn 10 on the roller 21 in suction pipe 44 thereby also can constitute by the attractive force that takes place being increased provisionally discard yarn with this suction pipe 44 attraction spun yarns 10.If utilize this formation, then can omit and separate line bar 28 and air cylinder 49 etc.
In addition, in the joint action that utilizes splicer 43, owing to utilize this splicer 43 to clamp yarn ends, so do not utilize suction pipe 44 to attract.Therefore, if for having made the state that line bar 28 rises of separating, then because the tip side of depositing roller 21 from yarn is separated easypro spun yarn 10 takes place to relax.In order to prevent this situation, in the action of splicer 43, make and separate line bar decline (D of Figure 10 constantly).Like this, because flier 38 engages with spun yarn 10, so that the tip side that spun yarn 10 is not deposited roller 21 from yarn is separated is easypro, then the yarn amount of storage deposited on the roller 21 of yarn increases lentamente as shown in figure 10.
If joint finishes, then cell controller restarts to utilize the coiling of the spun yarn 10 of wind2 13.The moment of the E of Figure 10 corresponding joints end constantly.This constantly after owing to utilize wind2 13 to apply yarn tension to spun yarn 10, thus spun yarn 10 deposited from yarn roller 21 separate easypro, thereby amount of storage reduces lentamente.
After this, the cell controller testing result of depositing roller 21 based on yarn is carried out the controlled reset of the yarn amount of storage of above-mentioned explanation.For example, deposit amount of storage on the roller 21 at yarn and become (F of Figure 10 constantly) under the situation less than the minimum amount of storage of necessity, driving figure mobile cylinder is slightly sowed discord package 45 from reel 72, thereby the yarn amount of storage is recovered.Under the yarn amount of storage becomes situation more than the specified value (G of Figure 10 is constantly), driving figure mobile cylinder slightly makes package 45 contact with reel 72, thus minimizing yarn amount of storage.
Be constituted as in the present embodiment: if necessitate more than the minimum amount of storage (C that becomes Figure 10 constantly after) in the amount of storage that yarn is deposited the yarn of roller 21, then cell controller switches to the pattern of utilizing yarn clearer 52 to carry out the supervision of yarn faults.That is, as shown in figure 10, because yarn tension is stable later on constantly at C, so can utilize yarn clearer 52 to carry out the detection of correct yarn faults.Be carved into during from the A of Figure 10 C constantly till, the spun yarn 10 (the unsettled yarn of quality) by yarn clearer 52 becomes and utilizes suction pipe 44 to hold and give up, so need not carry out the supervision of yarn faults.On the other hand, C constantly after spun yarn 10 by yarn clearer 52 in joint, be stored in yarn storing unit 12 and finally be wound in the package, so preferably carry out the supervision of yarn faults.Owing to aforesaid reason, (C constantly after) restarts the supervision of yarn faults after the amount of storage that yarn is deposited the spun yarn 10 on the roller 21 necessitates more than the minimum amount of storage.
In spinning machine in the past, deposit the yarn of the unstable quality on the roller 21 and have to be wound in the package owing to not giving up yarn, so also carried out the supervision of the defective of this unsettled yarn.At this, because the unsettled yarn of yarn qualities drawn from spinning apparatus 9 with lower tension force, so the yarn tension during by yarn clearer 52 is also low.Like this, the take place frequently detection action of yarn faults of the apparent thickness chap of the yarn that monitors owing to yarn clearer 52 has in order to prevent this situation to begin to change the condition enactment that yarn faults detects when common.Based on this point, in the present embodiment, owing to can give up the unsettled yarn of quality, so for this unsettled yarn and Yan Buxu monitors defective.Thereby, also can omit the control that relaxes the yarn faults testing conditions for unsettled yarn uses especially, so can simplify control.
Supplemental instruction: why can give up yarn as described above and deposit yarn on the roller 21 when joint, this is because as the downstream that line bar 28 is configured in yarn guide member 22 of separating of separating the line parts.Past, deposit in the spinning machine of roller 21 counterrotating yarn guide members 22 possessing relatively yarn, adopt be by upstream side guide rail 23 is constituted can before and after advance and retreat and this upstream side guide rail 23 is moved on progressive position, spun yarn 10 is controlled to the formation that does not engage with flier 38.
If for this constitutes, as long as do not depositing under the state of depositing yarn on the roller 21 at yarn fully, promptly whether may command hangs over spun yarn 10 on the yarn guide member 22, rolls up yarn but Once you begin deposit on the roller 21 at yarn, then can not untie spun yarn 10 from flier 38.Thereby, if the formation of separating the line parts in the upstream side setting of yarn guide member 22, then when joint, can not utilize the attraction of suction pipe 44 to give up to be rolled onto yarn to deposit unsettled yarn on the roller 21.Like this, present embodiment is separated line bar 28 by being provided with in the downstream of yarn guide member 22, becomes possibility thereby give up the unsettled yarn that yarn deposits on the roller 21.
As mentioned above, the Yarn processing method that utilizes the spinning frame 1 of present embodiment to carry out comprises that yarn catches operation, guide operation, amount of storage and increase operation and the discarded operation of yarn.In yarn was caught operation, when beginning to be rolled onto yarn from the spun yarn 10 of spinning apparatus 9 outputs and deposit roller 21, suction pipe 44 was by attracting to catch this spun yarn 10.In the guide operation, by making the spun yarn 10 that links to each other with suction pipe 44 with above-mentioned spinning apparatus 9 with respect to engage with yarn guide member 22 that yarn is deposited the rotation of roller 21 one, outer peripheral face from roller 21 to yarn that deposit guides this spun yarn 10.Increase in the operation in amount of storage, come to draw spun yarn 10 by outer peripheral face coiling spun yarn 10 from roller 21 to yarn that deposit, and be increased in the amount of storage that yarn is deposited the spun yarn of depositing on the roller 21 10 simultaneously from spinning apparatus 9.In the discarded operation of yarn, after amount of storage necessitates more than the minimum amount of storage, this amount of storage is remained more than the minimum amount of storage of above-mentioned necessity, and discard simultaneously at yarn and deposit the spun yarn of depositing on the roller 21 10.Then, after the discarded operation of above-mentioned yarn, move to the joint action.
Like this, can deposit on the roller 21, make haul-off tension stable by a certain amount of above spun yarn 10 is rolled onto yarn, thus can be from the spinning apparatus 9 stable spun yarns 10 of drawing.Deposit the amount of the yarn on the roller 21 when insufficient at yarn, sometimes can not be from spinning apparatus 9 stable and draw spun yarn 10 and quality of yarn becomes unstable, if utilize the Yarn processing method of present embodiment, then also can suitably tackle the generation of aforesaid unsettled yarn.Promptly, in the present embodiment, the unsettled part of the quality of spun yarn 10 can be wound to temporarily yarn is deposited on the roller 21 and guarantee to after the amount of storage more than the necessary minimum amount of storage, on one side the stable spun yarn 10 of winding quality discarded above-mentioned unsettled part on one side.Like this, when moving to the joint action, only can form and deposit the state of depositing stable spun yarn 10 on the roller 21 at yarn.
In the Yarn processing method of present embodiment, in the discarded operation of yarn,, attracting abolishment to deposit the yarn of depositing on the roller 21 on the suction pipe 44 at yarn by untiing spun yarn 10 from yarn guide member 22.Like this, can utilize the shirtsleeve operation of untiing yarn from yarn guide member 22, utilize suction pipe 44 to attract to abolish spun yarn 10.
In the Yarn processing method of present embodiment, if because the above spun yarn 10 that engage with this yarn guide member 22 of the necessary minimum amount of storage of volume and tension stability, then yarn guide member 22 is deposited roller 21 from yarn and is separated easypro this spun yarn 10.In the discarded operation of above-mentioned yarn, by the attractive force that increases suction pipe 44 tension force of the spun yarn 10 between this suction pipe 44 and the yarn guide member 22 is increased, deposit the spun yarn of depositing on the roller 21 10 thereby attract to abolish at yarn.Like this, owing to can utilize this suction pipe 44 to attract to abolish and the cooresponding spun yarn 10 of attractive force that increases suction pipe 44, thus need not possess the discarded special movable member that is used for spun yarn 10 etc., thus but cutting down cost.
The spinning frame 1 of present embodiment possesses spinning apparatus 9, wind2 13, yarn and deposits roller 21, yarn guide member 22 and separate line bar 28 as the yarn waste part.Thereby spinning apparatus 9 generates spun yarn 10 to fibrous bundle 8 twisting.Thereby wind2 13 is reeled and is formed package 45 from the spun yarn 10 of spinning apparatus 9 outputs.Yarn is deposited roller 21 by in outer peripheral face coiling spun yarn 10 and rotation, comes one side to give tension force to this spun yarn 10 and draws from spinning apparatus 9 on one side.Yarn guide member 22 can engage with spun yarn 10, by with state that this spun yarn 10 engages under deposit the rotation of roller 21 one with yarn, the outer peripheral face that stops spun yarn 10 to deposit roller 21 from yarn is separated easypro.Separate line bar 28 and be configured in the yarn conveyance direction downstream side of yarn guide member 22, be constituted as can the lowering position that does not contact with spun yarn 10 and with hoisting position that spun yarn 10 contacts between move.Then, this is separated line bar 28 and is constituted as when separating line bar 28 and be positioned at above-mentioned hoisting position and unties spun yarn 10 from separating line parts 22.
