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.

Technical field

The present invention relates to Yarn processing method and spinning machine.Particularly, the present invention relates to utilize yarn to deposit roller draws the processing of spun yarn and is used for the formation of this processing from spinning apparatus.

Background technology

TOHKEMY 2004-124333 communique discloses a kind of spinning machine that possesses spinning apparatus, conveying roller (delivery roller), yarn defect detecting device and yarn storing unit (Yarn relaxation eliminating device).On conveying roller, dispose in opposite directions niproll (nip roller).Spun yarn is held between conveying roller and the niproll.Give to the tension force in the downstream of yarn direct of travel to the yarn of above-mentioned clamping by driving the conveying roller rotation, draw yarn from spinning apparatus thus.The yarn storing unit is configured in the downstream of conveying roller, possesses the yarn that yarn can be rolled onto its periphery and deposits roller (Yarn relaxation elimination roller).Drive this yarn and deposit roller and be rotated, will be rolled onto from the spun yarn that spinning apparatus is exported continuously its periphery and deposit for the moment.Like this, yarn is deposited the lax of the spun yarn that occurs when roller prevents joint.Yarn defect detecting device is configured between conveying roller and the yarn storing unit, detects the defective of spun yarn by the thickness that monitors spun yarn.

In aforesaid spinning machine, be rolled onto yarn at the spun yarn that does not have sufficient length and deposit in the situation on the roller, the area of contact that yarn is deposited between roller and the spun yarn is not enough.Consequently, deposit at this yarn and to skid between roller and the spun yarn (slip), thereby reduce than the yarn tension of yarn storing unit near upstream side.Therefore, be preferably in all the time and deposit roller at yarn and deposit and drive this yarn under the state of the yarn more than a certain amount of and deposit the roller rotation.But, when joint, be in to the yarn of dummy status and deposit roller volume spun yarn, therefore can not avoid the inadequate state of yarn amount of storage.Therefore, the reduction that (especially when joint begins) deposits the upstream side generation yarn tension of roller at yarn when joint.

If yarn tension reduces as mentioned above, the problem that then exists the detection degree of precision utilize the yarn faults that yarn defect detecting device carries out to reduce.That is, because the yarn faults detector detects yarn faults by the thickness that monitors yarn, thus if the apparent thickness chap of the spun yarn that yarn tension reduces, the thickness inequality that then sometimes usually allows would be used as yarn faults and would detect.Consequently, spinning unit frequent operation ground stops.In addition, in order to prevent that this phenomenon from considering when joint begins provisionally the condition that detects than usually relaxing yarn faults.But, can not detect the yarn faults that originally should remove yarn qualities reduced thereby become sometimes in the method.Like this, critically carry out well the detection of yarn faults in the time of can not be at joint in possessing yarn and deposit the spinning machine of roller.

But skidding of the yarn that causes because of the Clamping force deficiency etc. occurs easily in above-mentioned niproll when drawing yarn from spinning apparatus.On the other hand, above-mentioned yarn deposit roller if under the state of the spun yarn of outer peripheral face volume sufficient length rotary actuation, just can stablize also tractive yarn.Being conceived to this point considers to omit above-mentioned conveying roller and forms and utilize above-mentioned yarn storing unit directly to draw the formation of yarn from spinning apparatus.The spinning machine that in addition in the following description, will possess such feature is called without the conveying roller spinning machine.

This can be to draw spun yarn than the more stable tension force of spinning machine that uses conveying roller from spinning apparatus without the conveying roller spinning machine, therefore thinks the package that can form the homogeneous quality.But, even without the spinning machine center tap of conveying roller the time the inadequate situation of yarn amount of storage that yarn is deposited roller can occur also, at this moment, the problem of the degree of precision deficiency that detects except aforesaid yarn faults, problem as described below occurs also.That is be to utilize the yarn storing unit directly to draw the formation of spun yarn from spinning apparatus without the spinning machine of conveying roller, so in the situation of the variation of this yarn storing unit tractive spun yarn, can greatly affect the quality of the yarn of spinning unit.Thereby if the yarn amount of storage becomes insufficient and yarn tension reduces when beginning as joint, then the quality of yarn becomes unstable.In addition, in the following description, sometimes with the spinning unit steady quality of the spun yarn in the spinning apparatus or unstablely be called simply " stablizing ", " unstable ".

The become insufficient and unsettled spun yarn of quality of the detection degree of precision of yarn faults is wound to possibility in the package when as mentioned above, having joint in the spinning machine without conveying roller.

Summary of the invention

The invention that the present invention In view of the foregoing finishes just, its main purpose be, provides a kind of when omitting the spinning machine of conveying roller, can also prevent that when the joint unsettled part of yarn qualities from sneaking into the spinning machine of package.

As the first viewpoint of the present invention, Yarn processing method comprises that yarn catches operation, guide operation, amount of storage increases operation and yarn is discarded operation.Catch in the operation at above-mentioned yarn, the yarn capture unit is by attracting to catch this spun yarn when beginning to be rolled onto yarn from the spun yarn of spinning apparatus output and deposit on the roller.In above-mentioned guide operation, by making the above-mentioned spun yarn that links to each other with above-mentioned yarn capture unit with above-mentioned spinning apparatus with respect to engage with yarn guiding part that above-mentioned yarn is deposited the rotation of roller one, outer peripheral face from roller to above-mentioned yarn that deposit guides this spun yarn.Increase in the operation in above-mentioned amount of storage, reel above-mentioned spun yarn and draw above-mentioned spun yarn from above-mentioned spinning apparatus by outer peripheral face from roller to above-mentioned yarn that deposit, and the amount of storage of depositing the above-mentioned spun yarn that roller deposits at this yarn is increased.In the discarded operation of above-mentioned yarn, after above-mentioned amount of storage becomes more than the specified amount, this amount of storage is remained on more than the afore mentioned rules amount, and discard simultaneously at above-mentioned yarn and deposit the above-mentioned spun yarn that roller is deposited.Then, after the discarded operation of above-mentioned yarn, move to next and process action.

Like this, can make haul-off tension stable and then stablize and draw spun yarn from spinning apparatus by deposit a certain amount of above spun yarn of roller volume at yarn.In addition, deposit the amount of the yarn on the roller when insufficient at yarn, thereby quality that is sometimes can not be from spinning apparatus stable and that draw the spun yarn yarn becomes unstable, and in the present invention, even also can suitably tackle for the generation of so unsettled yarn.That is, if utilize above-mentioned Yarn processing method, thereby then can interim the unsettled part of the quality of yarn is wound to yarn deposit guarantee sufficient amount of storage on the roller after, on one side the stable yarn of winding quality discarded above-mentioned unsettled part on one side.Like this, when moving to next processing action, can form and only leave the state that yarn is deposited yarn stable on the roller in.

Above-mentioned Yarn processing method is preferably taked following method.That is, in the discarded operation of above-mentioned yarn, by untiing above-mentioned yarn from above-mentioned yarn guiding part, will deposit the above-mentioned yarn that roller deposits at above-mentioned yarn and attract to abolish to above-mentioned yarn capture unit.Like this, can by untie the shirtsleeve operation of yarn from yarn guiding part, utilize the yarn capture unit to attract to abolish yarn.

In above-mentioned Yarn processing method, if above-mentioned yarn guiding part is constituted as the above-mentioned yarn tension stability that engages with this yarn guiding part because of more than the volume afore mentioned rules amount, then deposits roller from above-mentioned yarn and separate this yarn that relaxes.Then, in the discarded operation of above-mentioned yarn, by the attractive force that increases above-mentioned yarn capture unit the tension force of the above-mentioned yarn between this yarn capture unit and the above-mentioned yarn guiding part is increased, deposit the above-mentioned yarn that roller is deposited thereby attract to abolish at above-mentioned yarn.Like this, can only utilize this yarn capture unit to attract to abolish yarn by the attractive force that increases the yarn capture unit, so need not possess for the special movable member of the abolishment of yarn etc., thereby but cutting down cost.

As the 2nd viewpoint of the present invention, spinning machine possesses spinning apparatus, wind2, yarn and deposits roller, yarn guiding part and deposit the yarn waste part.Above-mentioned spinning apparatus generates spun yarn to fibrous bundle twisting.Thereby above-mentioned wind2 is reeled and is formed package from the above-mentioned spun yarn of above-mentioned spinning apparatus output.Above-mentioned yarn is deposited roller and is given tension force and draw from above-mentioned spinning apparatus simultaneously to this yarn by roll up above-mentioned spun yarn and rotation to outer peripheral face.Above-mentioned yarn guiding part can engage with above-mentioned spun yarn, by with state that this spun yarn engages under deposit the outer peripheral face that the rotation of roller one deposits roller to above-mentioned yarn with above-mentioned yarn and roll up above-mentioned spun yarn.Above-mentionedly deposit that the yarn waste part is discarded to be wound to above-mentioned yarn and to deposit above-mentioned spun yarn on the roller.

Like this, draw spun yarn by deposit on the roller a certain amount of above spun yarn of volume to yarn, tension stability is drawn spun yarn thereby can stablize from spinning apparatus.In addition, deposit the amount of the spun yarn on the roller when insufficient at yarn, thereby sometimes can not become unstable from the stable quality of drawing the spun yarn spun yarn of spinning apparatus.But, even in the present invention for the generation of so unsettled spinning unit, also can suitably tackle.That is, if utilize formation of the present invention, thereby then can interim the unsettled part of the quality of yarn is wound to yarn deposit guarantee sufficient amount of storage on the roller after, on one side the stable spun yarn of winding quality, on one side discarded above-mentioned unsettled part.Like this, become and only leave the state that yarn is deposited spun yarn stable on the roller in.Thereby, can prevent from sneaking into to package the unsettled part of spun yarn, so can make the measured package of matter.

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 yarn is deposited the side with yarn guide member 22 of outer peripheral face 21a of roller 21 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 successively to the top.

Cylindrical portion 21c constitutes the slightly thin shape of tip side, does not have poorly continuous shape of ladder 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 the yarn amount of storage that detects.

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 respectively the end face side.Deposit among the outer peripheral face 21a of roller 21 at yarn, base end side cone part 21b is constituted as by the spun yarn 10 of having supplied with successfully being moved from the major diameter part to small diameter portion and making it arrive the surface that middle cylindrical portion 21c fitly is rolled onto spun yarn 10 cylindrical portion 21c.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 from rolling up comes off for the moment, carries successively and warp spun yarn 10 guarantees the function of drawing smoothly of spun yarns 10 thereby also have simultaneously for the part of the major diameter from small diameter portion to the end face side.

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 with the relative rotation ingot axle 33 relatively.On the other hand, deposit mounting permanent magnet on any one party of roller 21 at ingot axle 33 or yarn, and the opposing party magnetic hysteresis part (hysteresis) is installed.Under the effect of these magnetic mechanisms, antagonism yarn guide member 22 relative yarns occur 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 in 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 with spun yarn 10 shape of (hook 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 to the yarn of rotation deposit roller 21 outer peripheral face guiding, reel.

Below deposit the spun yarn 10 on the roller 21 to twisting in yarn situation describe.That is, be guided through the spun yarn 10 of upstream side guide rail 23 from base end side to outer peripheral face 21a, be wound many times at cylindrical portion 21c.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 for the relax power that makes yarn guide member 22 rotations of spun yarn 10 of the top ends solution of depositing roller 21 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 more can be rotated independently, thereby the tip side that spun yarn 10 is deposited roller 21 from yarn is lentamente separated by flier 38 and relaxed.

On the contrary, the yarn tension in the downstream of yarn storing unit 12 is not enough to overcome in 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 easypro effect of tip side solution that stops spun yarn 10 to deposit roller 21 from the yarn of rotation.

Like this, yarn storing unit 12 can utilize when the tension force raising of the yarn in downstream and separate the easypro action of solution 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 applies to the spun yarn 10 between yarn storing unit 12 and the wind2 13 as above above-mentionedly, and the influence of change that prevents this tension force is 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 with more stable speed from spinning apparatus 9.

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 easypro velocity ratio of tip side solution of depositing roller 21 at spun yarn 10 from yarn is rolled onto in the fireballing situation of base end side, and the yarn amount of storage reduces, and in the situation that spun yarn 10 does not relax from the tip side solution, the yarn amount of storage increases lentamente.

In addition, yarn storing unit 12 possesses the line of solution bar 28 as mentioned above.As shown in Figure 4, this solution line bar 28 is formed the parts of the approximate L font of the elongated portion (service portion 28a) with horizontal arrangement.Separate the base portion of line bar 28 and supported that by axis of rocking 28b this solution line bar 28 is constituted as and can fluctuates centered by the above-mentioned axis of rocking 28b between hoisting position and lowering position.When solution line bar 28 was positioned at lowering position (the 1st position, transferring position, for example position shown in Figure 2), solution line bar 28 was not constituted as and contacts with the yarn road of spun yarn 10.On the contrary, when solution line bar 28 is positioned at hoisting position (the 2nd position, in-position, for example position shown in Figure 5), thereby promoting the yarn road of spun yarn 10, above-mentioned service portion 28a unties spun yarn 10 from flier 38.This solution line bar 28 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 come to untie spun yarn 10 from separating line parts 22 by making solution line bar 28 move to hoisting position.Resistance when the tip side solution of like this, depositing roller 21 from yarn is relaxed spun yarn 10 (resistance torque that applies to yarn guide member 22) does not act on yarn.Consequently, even deposit at yarn in the situation a little less than the yarn tension in downstream of roller 21, also can deposit roller 21 from this yarn and separate the yarn that relaxes.Do not deposit to make under the state on the roller 21 and separate line bar 28 and rise if be rolled onto yarn at yarn, then can stop flier 38 to engage with spun yarn 10, be not wound to yarn and deposit on the roller 21 so can be controlled to spun yarn 10.

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, basically 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.That is, winding speed is more fast than line sending speed, and the tension force that then applies to yarn becomes larger, and is easypro thereby yarn is deposited roller 21 solutions from yarn lentamente.On the contrary, winding speed is more slow than line sending speed, and the tension force that then applies to yarn becomes less, 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 the spun yarn 10 that yarn deposits on the roller 21 and separate relaxed lentamente, 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 inertial 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 surpassing the spun yarn 10 of the amount that can deposit to cylindrical portion 21c is wound to yarn and deposits on the roller 21, 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 and relax 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 to regulate the winding speed of wind2 13.Can deposit by detecting yarn the yarn amount of storage of roller 21 and feed back and carry out simultaneously the control of the winding speed of wind2 13, 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 is wound device 13 and temporarily is wound in the package 45.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 marches to before this spinning unit 2 it to joint chassis 3 pipage control signals, 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 occur to utilize simultaneously.Like this, draw yarn ends (yarn under working) from the outer peripheral face of package 45, attracted to catch by suction nozzle 46.In addition, can by drawing the yarn that contains above-mentioned yarn faults from package 45 and then being held by suction nozzle 46, come to remove the yarn that contains above-mentioned yarn faults from package 45 this moment.

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 rotation 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 again, thereby attract simultaneously stream that the yarn ends (upper yarn) (yarn seizure operation) of spinning apparatus 9 sides occurs to catch in suction pipe 44.The yarn tension of this moment and yarn amount of storage represent constantly with the A of the diagram of curves of Figure 10.As shown in figure 10, constantly only attract yarn under the effect in the attractive force of suction pipe 44 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 makes solution line bar 28 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, can not utilize the attractive force of suction pipe 44 to deposit roller 21 by the easypro spun yarn 10 of yarn guide member 22 solutions from yarn.Therefore, if deposit roller 21 winding yarns to yarn finishing before the splicer 43 guiding yarn ends beginning, then suction pipe 44 can not be than yarn on its larger ground tractive, thus upper yarn can not be guided to splicer 43, thus joint is unsuccessfully.Therefore, by finishing before splicer 43 guiding suction pipes 44, to make 28 risings of solution line bar prevent that spun yarn 10 from beginning to deposit roller 21 to yarn and reeling.

Fig. 5 and Fig. 6 have described suction pipe 44 and have carried out simultaneously rotation action with suction nozzle 46, and rotation action can be for before, also can for after.

If upper yarn finishes to the guiding of splicer 43, then make and separate the control that line bar 28 descends rapidly.Like this, the spun yarn 10 that is connected between spinning apparatus 9 and the suction pipe 44 engages with flier 38, 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, although 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 occur.Therefore, deposit on the roller 21 by spun yarn 10 being rolled onto yarn, can prevent the lax of spun yarn 10.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, constantly represent the moment that this solution line bar 28 descends with B.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 till yarn is deposited roller 21 to deposit spun yarn 10 more than the necessary minimum amount of storage during, deposit between roller 21 and the spun yarn 10 at yarn and to skid easily, thus unstable from the haul-off tension of the yarn of spinning apparatus 9.Thereby, can say until till yarn is deposited roller 21 to deposit the yarn of q.s (necessary minimum amount of storage) during (between the BC of Figure 10), 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 to splicer 43 guiding yarn ends, after this begin immediately the joint between the yarn ends of splicer 43.But, have unsettled thread segment owing to deposit roller 21 at yarn as mentioned above, so if carry out joint under this state, then this unsettled thread segment is wound in the package 45.

Therefore, be blended in the package 45 in order to prevent this unsettled part, the spinning frame 1 of present embodiment is consisted of as described below.

At first, can not begin immediately joint even cell controller is guided to splicer 43 at upper yarn by suction pipe 44 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.In the situation of yarn amount of storage less than the minimum amount of storage of necessity, separate line bar 28 and be in the decline state spun yarn 10 that remains unchanged to reel by making.If utilizing yarn amount of storage sensor 27 to detect the yarn amount of storage necessitates (the C moment of Figure 10) more than the minimum amount of storage, then cell controller utilizes air cylinder 49 to make solution line bar 28 move 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 owing to stop the relax resistance of spun yarn 10 of the top ends solution of depositing roller 21 from yarn to disappear, so even become under the effect of the weak attractive force of suction pipe 44, also can separate the spun yarn 10 that relaxes.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 top ends of depositing roller 21 at this yarn only occurs to deposit the lax of the suitable spun yarn 10 of the amount of roller 21 rotations with 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 again reeling, 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, again be rolled onto the steady quality of spun yarn 10 that yarn is deposited the base end side of roller 21 so can make.Then, because from the spun yarn 10 of base end side roll stabilizing and on the contrary at the tip side solution unsettled spun yarn 10 that relaxes, so yarn is deposited the spun yarn 10 that yarn on the roller 21 is replaced as stabilised quality successively.

If relax by the solution that makes 28 risings of solution line bar begin unsettled yarn, then 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, deposit from yarn and all to give up the unsettled 10 necessary times of spun yarn 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, even then do not untie spun yarn 10 from flier 38, also can deposits roller 21 from yarn and separate the spun yarn 10 that relaxes.But, if often overcome the attractive force of the resistance torque of yarn guide member 22, then the loss of energy is large.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 thereby also can constitute by the attractive force that occurs being increased provisionally discard yarn with this suction pipe 44 attraction spun yarns 10 in suction pipe 44.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 separate the state that line bar 28 rises for making, the spun yarn 10 that then relaxes owing to the tip side solution of depositing roller 21 from yarn occurs lax.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 spun yarn 10 is not deposited the tip side solution of roller 21 from yarn 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 constantly corresponding joints end of the E of Figure 10.After this moment, owing to utilize wind2 13 to apply yarn tension to spun yarn 10, relaxed so spun yarn 10 deposits roller 21 solutions from yarn, 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) in 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, owing to the yarn that can not give up yarn and deposit the unstable quality on the roller 21 has to be wound in the package, so also carried out the supervision of the defective of this unsettled yarn.At this, owing to the unsettled yarn of yarn qualities is drawn from spinning apparatus 9 with lower tension force, so the yarn tension when passing through 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 is had to begin when common to change the condition that yarn faults detects and is set in order to prevent this situation.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 especially the yarn faults testing conditions for unsettled yarn uses, so can simplify control.

Supplemental instruction: why can give up as described above yarn and deposit yarn on the roller 21 when joint, this is because be configured in the downstream of yarn guide member 22 as the solution line bar 28 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 make this upstream side guide rail 23 mobile at progressive position, spun yarn 10 is controlled to the formation that does not engage with flier 38.

Consist of if be this, as long as do not depositing under the state of yarn depositing roller 21 at yarn fully, can control and whether spun yarn 10 is hung on the yarn guide member 22, roll up yarn but Once you begin deposit roller 21 at yarn, then can not untie spun yarn 10 from flier 38.Thereby, if at the upstream side of yarn guide member 22 formation of separating the line parts is set, 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 arranges by the downstream at yarn guide member 22 and separates line bar 28, 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 increases operation and the discarded operation of yarn.In yarn 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 from spinning apparatus 9 by outer peripheral face coiling spun yarn 10 from roller 21 to yarn that deposit, and be increased in simultaneously the amount of storage that yarn is deposited the spun yarn 10 of depositing on the roller 21.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 10 that roller 21 is deposited.Then, after the discarded operation of above-mentioned yarn, move to the joint action.

Like this, can deposit on the roller 21 by a certain amount of above spun yarn 10 is rolled onto yarn, make haul-off tension stable, 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 quality that is can not be from spinning apparatus 9 stable and that draw spun yarn 10 and yarn becomes unstable, if utilize the Yarn processing method of present embodiment, then also can suitably tackle the generation of aforesaid unsettled yarn.Namely, 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 as 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 that roller 21 is deposited stable spun yarn 10 at yarn.

In the Yarn processing method of present embodiment, in the discarded operation of yarn, by untiing spun yarn 10 from yarn guide member 22, attract abolishment to deposit the yarn that roller 21 is deposited at yarn at suction pipe 44.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 10 that roller 21 is deposited thereby attract to abolish at yarn.Like this, owing to can utilize this suction pipe 44 to attract to abolish the spun yarn 10 suitable with the attractive force that increases suction pipe 44, so need not possess for the discarded special movable member of spun yarn 10 etc., thereby but cutting down cost.

The spinning frame 1 of present embodiment possesses that spinning apparatus 9, wind2 13, yarn are deposited roller 21, yarn guide member 22 and as the solution line bar 28 of 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 solution that stops spun yarn 10 to deposit roller 21 from yarn is relaxed.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 contact with spun yarn 10 and with hoisting position that spun yarn 10 contacts between movement.Then, this solution line bar 28 is constituted as when solution line bar 28 is positioned at above-mentioned hoisting position and unties spun yarn 10 from separating line parts 22.

Like this, can deposit roller 21 by a certain amount of above spun yarn 10 is rolled onto yarn, make haul-off tension stable, 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 become unstable from spinning apparatus 9 stable quality of drawing spun yarn 10 and yarn, if be the formation of present embodiment, then also can suitably tackle the generation of aforesaid unsettled yarn.That is, in the present embodiment, the unsettled part of the quality of spun yarn 10 can be wound to temporarily after yarn deposits on the roller 21, on one side the stable yarn 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 that roller 21 is deposited stable spun yarn 10 at yarn.Thereby, can prevent from package 45, sneaking into the unsettled part of yarn, so can make the measured package 45 of matter.In addition, can also utilize to make and separate the simple formation that line bar 28 moves and so on, untie spun yarn 10 from separating line parts 22, separate this unsettled part of relaxing thereby deposit roller 21 from yarn.

The spinning frame 1 of present embodiment possesses the air cylinder 49 that drives solution line bar 28 by lift arm 47.Air cylinder 49 is deposited in the situation of spun yarn 10 less than the minimum amount of storage of necessity on the roller 21 being rolled onto yarn, makes to separate line bar 28 and become lowering position.Air cylinder 49 is deposited after spun yarn 10 on the roller 21 necessitates more than the minimum amount of storage being rolled onto yarn, makes to separate line bar 28 and become hoisting position.

Namely, if being wound to yarn at the yarn that does not have q.s deposits and begins to deposit roller 21 from this yarn under the state on the roller 21 and separate the spun yarn 10 that relaxes, then the unsettled part of the quality of yarn continuously is wound to yarn and is deposited on the roller 21, so can not deposit the yarn that roller 21 is deposited stable quality at yarn.Based on this point, if utilize formation of the present invention, thereby then can yarn is rolled onto fully yarn deposit become on the roller 21 from spinning apparatus 9 stable draw the state of spun yarn 10 after, separate the yarn that relaxes and deposit spun yarn 10 on the roller 21.Thereby, be replaced as successively after thereby stay-in-grade part all separates the unsettled part of Shu Shangshu in the unsettled part that yarn is deposited the spun yarn 10 on the roller 21, only have to become from spinning apparatus 9 stable spun yarns 10 of drawing to be wound to yarn and to deposit state on the roller 21.

The spinning frame 1 of present embodiment possesses the yarn clearer that has or not 52 of the yarn faults that monitors spun yarn 10.Then, yarn clearer 52 is deposited spun yarn 10 on the roller 21 less than the supervision of the lower broken yarn line defect of the situation of the minimum amount of storage of necessity being rolled onto yarn.Yarn clearer 52 is deposited the supervision that spun yarn 10 on the roller 21 restarts yarn faults after necessitating more than the minimum amount of storage being rolled onto yarn.

That is, if be wound to the supervision that yarn is deposited beginning yarn faults under the state on the roller 21 at the yarn that does not have q.s, then can not obtain correct testing result because yarn tension is unstable.From based on this point, if utilize formation of the present invention, then deposit in the inadequate situation of amount of the yarn on the roller 21 at yarn, can interrupt the supervision of yarn faults, yarn is rolled onto fully yarn is deposited on the roller 21 and from spinning apparatus 9 stable draw the state of spun yarn 10 after, restart the supervision of yarn faults.Thereby, after separating the unsettled part of Shu Shangshu, form and only have the yarn that has or not of normally being judged yarn faults to be wound to yarn to deposit state on the roller 21.In addition, because as long as only begin to carry out the supervision of yarn faults from the stable moment of yarn tension, the setting of change yarn faults detection so do not need when yarn qualities is unstable for this reason, thus can simplify control.

In the spinning frame 1 of present embodiment, air cylinder 49 make separate line bar 28 to become hoisting position after through specified time after, make this solution line bar 28 get back to lowering position.Like this, can be to deposit the unsettled part of separating the spun yarn 10 that relaxes on the roller 21 fully from yarn after, the solution of ending spun yarn 10 is relaxed, and only will deposit in yarn from spinning apparatus 9 spun yarns 10 stable and that draw and deposit on the roller 21.

The spinning machine 1 of present embodiment possesses splicer 43 and can utilize attraction stream to catch from the spun yarn 10 of spinning apparatus 9 and the suction pipe 44 that guides to splicer 43.Air cylinder 49 spun yarn 10 guided to splicer 43 by suction pipe 44 and be rolled onto yarn deposit spun yarn 10 on the roller 21 necessitate more than the minimum amount of storage after and beginning to utilize before splicer 43 carries out joint, make and separate line bar 28 and become hoisting position.
