Description
Technical field
The present invention relates to can be according to the abnormal weaving loom of the judgement textile yarns such as the tension force of textile yarn.
Background technology
All the time, known a kind of weaving loom, its have the surrounding of roller in rotation reel textile yarn, and textile yarn is held to the yarn staying temporarily and holds and stay device.TOHKEMY 2004-277949 communique (patent documentation 1) discloses this weaving loom.
In the weaving loom of patent documentation 1, in yarn moving direction, at yarn, hold the Yarn tension detection apparatus that stays the upstream of device to dispose the tension force that detects textile yarn.This Yarn tension detection apparatus has metal screw mandrel (wire rod) and switch block etc.Metal screw mandrel holds to stay on device at yarn and does not hold under the state that stays textile yarn and do not contact with textile yarn.On the other hand, hold to stay on device hold after the textile yarn leaving to a certain degree at yarn, metal screw mandrel contacts with textile yarn.Here, the power that metal screw mandrel is subject to from textile yarn stays the allowance of holding of device to increase and increase along with yarn holds.And in the situation that the power more than threshold value that metal screw mandrel is stipulated from textile yarn (staying the yarn of device to hold allowance for more than regulation in the situation that yarn holds), the output of the switch block being connected with metal screw mandrel is switched to ON from OFF.In addition, afterwards, in the situation that yarn holds, stay the yarn of device to hold allowance minimizing, the output of switch block is switched to OFF from ON.
The weaving loom of patent documentation 1 can be judged like this that yarn holds and stay the yarn of device to hold allowance.In addition, this weaving loom is in the situation that be judged to be yarn and hold and stay the yarn of device to hold allowance few (switch block OFF), thereby the control that slows down winding speed makes yarn hold allowance, increases.
At yarn, hold and stay the yarn of device to hold in the inadequate situation of allowance, the tension change of wind2 side can directly transmit to textile apparatus side.In this situation, likely cause the quality badness of textile yarn.In addition, in the following description, the textile yarn of this quality badness is called to abnormal yarn.
As previously mentioned, the weaving loom of patent documentation 1 only according to tension force be whether threshold value with on judge that yarn holds and stay the yarn of device to hold allowance.But, even also exist yarn to hold to stay the yarn of device to hold allowance according to weaving condition, be the situation that zero tension force also changes hardly.Therefore,, in the weaving loom of patent documentation 1, existence cannot be held the situation that the situation (likely sneaking into abnormal yarn in package) of allowance vanishing detects to yarn.
In addition, even to stay the yarn of device to hold allowance few in the situation that yarn holds, exist inferiorly in the slow situation of winding speed, yarn holds the situation of the impact of the tension change that stays device can absorb wind2 side.But, in the weaving loom of patent documentation 1, because being holds allowance few in the situation that at yarn, the formation that textile yarn can leave from Yarn tension detection apparatus, so, cannot detect the tension force that yarn holds the textile yarn in the situation that allowance is few.Therefore, even in the situation that wind2 is suitably reeled, also there is the possibility of the control that slows down winding speed in the weaving loom of patent documentation 1.
In sum, in patent documentation 1, cannot accurately judge whether textile yarn exists extremely.
Summary of the invention
The object of the present invention is to provide a kind of formation, hold in the weaving loom that stays device thering is yarn, can judge in textile yarn, whether exist abnormal.
According to viewpoint of the present invention, weaving loom has: yarn feeder, test section, yarn hold and stay device, wind2, detection unit.Described yarn feeder is supplied with textile yarn.Described test section is configured in the yarn moving direction downstream of described yarn feeder, and the tension force of described textile yarn is detected.Described yarn holds and stays device to be configured in the yarn moving direction downstream of described test section, and described textile yarn is held and stayed.Described wind2 is configured in described yarn and holds the yarn moving direction downstream of staying device, and described textile yarn is wound in to package.The speed of the tension force of the described textile yarn that described detection unit detects according to described test section and the described textile yarn that is wound to described package is winding speed, judges the abnormal of described textile yarn.
Thus, the tension change of the wind2 side causing according to the variation by winding speed and the correlativity of the tension force that test section detects, can hold yarn and hold the tension change that stays device whether can absorb wind2 side.Therefore, can judge in textile yarn and whether exist extremely.
In described weaving loom, preferably, the variable quantity of the tension force that described detection unit detects according to described test section and the variation of described winding speed extremely judging described textile yarn.
Thus, can further hold reliably yarn and hold the tension change that stays device whether can absorb wind2 side, so, can further judge exactly in textile yarn and whether exist extremely.
Described weaving loom, has the contact roller that contacts and be rotated with described package.The tension force that described detection unit detects according to described test section and described package or the described rotative speed that contacts roller, to extremely judging of described textile yarn.
Thus, can infer from the variation of the rotative speed of package or contact roller the variation of winding speed, so, can change and judge the abnormal of textile yarn according to this.
Described weaving loom has makes to be wound on the traverse gear that the described textile yarn in described package traverses.The speed of traversing of the tension force that described detection unit detects according to described test section and described traverse gear, to extremely judging of described textile yarn.
Thus, owing to inferring the variation that winding speed from the variation of the speed of traversing of traverse gear, so, can change and judge the abnormal of textile yarn according to this.
In described weaving loom, preferably also there is periodic Control portion, the periodic Control that this periodic Control portion periodically changes described winding speed.
Thus, can prevent that the textile yarn being wound is gathered in same position and overlapping so-called overlapping coiling occurs.In addition, due to winding speed is periodically changed, so, can further understand the correlativity of the tension force that the tension change of wind2 side and test section detect, so, can judge more accurately in textile yarn, whether exist abnormal.
In described weaving loom, preferably, the tension force before 1 cycle of the tension force that described detection unit detects described test section and described periodic Control compares, and judges the abnormal of described textile yarn according to this comparative result.
Thus, owing to can detecting yarn, hold the situation of staying device cannot absorb the tension change of wind2 side, so, can promptly detect abnormal situation has occurred in textile yarn.
In described weaving loom, described detection unit is poor according to the maxim of the tension force that during at least 1 cycle of described periodic Control, described test section detects and minimum value preferably, to extremely judging of described textile yarn.
Thus, the impact that sense cycle is controlled reliably shows that yarn holds the situation on the tension force of the upstream side that stays device, can judge the abnormal of textile yarn.Therefore,, even in the situation that yarn for example cannot be detected and hold and stay device can not absorb moment of the tension change of wind2 side, also can judge the abnormal of textile yarn.
In described weaving loom, preferably, described test section can hold and stay the yarn of device to hold allowance to detect independently mutually tension force with described yarn.
Thus, even to stay the yarn of device to hold allowance less in the situation that yarn holds, also can judge the abnormal of textile yarn.
In described weaving loom, preferably also there is winding control portion, at described detection unit, be judged to be and in described textile yarn, exist abnormal in the situation that, described winding control portion at least makes described yarn feeder and described wind2 stop.
Thus, can prevent from the textile yarn that comprises abnormal yarn to continue to be wound in package.
In described weaving loom, preferably there is informing portion, at described detection unit, be judged to be and in described textile yarn, exist abnormal in the situation that, described informing portion informs that this is abnormal.
Thus, owing to can existing abnormal situation to inform operator in textile yarn, so, for example can carry out as early as possible corresponding disposal.
In described weaving loom, preferred described detection unit to described yarn hold stay the yarn of device to hold allowance whether deficiency is judged.
Thus, owing to can yarn being held to allowance, whether deficiency is judged, so, can make yarn hold processing that allowance increases etc. according to result of determination.
In described weaving loom, preferred described yarn feeder is for to flow by rotary air the air textile apparatus of fibrous bundle being twisted and generated textile yarn.
That is, air textile apparatus is owing to can carrying out high speed weaving, so the winding speed of the textile yarn in wind2 is also very fast.Therefore, need to consider that yarn holds stays the yarn of device to hold situation that allowance sharply reduces etc.Therefore, can bring into play better the effect that the situation that can hold allowance deficiency according to yarn is judged abnormal this application of textile yarn.

The specific embodiment
Below, with reference to the accompanying drawings of the spinning frame (weaving loom) of an embodiment of the invention.Spinning frame 1 shown in Fig. 1 has: a plurality of weavings unit 2 being arranged side by side, connect yarn chassis 3, primary mover case 5, air blast cabinet 80, board control setup 90.
Board control setup 90 is to form for each that spinning frame 1 is had the device that carries out centralized management, has monitoring device (informing portion) 91 and enter key 92.In addition, operator utilizes enter key 92 to carry out suitable operation, and thus, the setting of can make specifically to weave unit 2 or whole weaving unit 2 and/or state etc. are presented in monitoring device 91.
As shown in Figure 2, each unit 2 of weaving has: the drafting assembly 7, textile apparatus (air textile apparatus) 9, the yarn that from upstream, configure successively downstream hold and stay device 12, wind2 13.In addition ”Ji“ downstream, this specification sheets Zhong“ upstream, " refer to upstream and the downstream of the fibrous bundle in when weaving and the moving direction of textile yarn.Thereby each is weaved, weaved and generated textile yarn 10 by 9 pairs of fibrous bundles of sending here from drafting assembly 78 of textile apparatus in unit 2, by 13 pairs of these textile yarns 10 of wind2, reeled and formed package 45.
In front roller 20Zheng downstream, dispose textile apparatus (yarn feeder) 9.Fibrous bundle 8 by drafting assembly 7 drawing-offs is supplied with to textile apparatus 9.The 9 pairs of fibrous bundle of supplying with from drafting assembly 78 twisting of textile apparatus, generate textile yarn 10.In present embodiment, adopt and utilize the textile apparatus of swirling eddy to the air type of fibrous bundle 8 twisting.Specifically, in textile apparatus 9, though omitted detailed explanation and diagram, have: fibre guide portion, rotary current generation nozzle, hollow guiding axis body.Fibre guide portion leads the fibrous bundle of sending here from drafting assembly 78 to the weaving chamber that is formed at the inside of textile apparatus 9.In the path of fibrous bundle 8 around, rotary current generation nozzle arrangement makes to weave indoor generation rotary current.By this rotary current, the fibre end of the indoor fibrous bundle 8 of weaving reverses and rotates.Hollow guiding axis body is the external orientation from weaving chamber to textile apparatus 9 by the textile yarn of being weaved 10.
In the downstream of textile apparatus 9, be provided with textile state detector (test section) 52, yarn quality analyzer 57.By the spun textile yarn 10 of textile apparatus 9, pass through described yarn quality analyzer 57 and textile state detector 52.
In yarn quality analyzer 57 and textile state detector 52 downstream, being provided with yarn holds and stays device 12.As shown in Figure 2, yarn holds and stays device 12 to have: yarn holds and stays roller 14, rotarilys actuate this yarn and hold the electro-motor 25 that stays roller 14.
Yarn holds and stays roller 14 also to hold and to stay temporarily at the textile yarn 10 of its outer peripheral face coiling constant basis.At yarn, hold under the state of the textile yarn 10 of having reeled on the outer peripheral face that stays roller 14, by this yarn is held, stay roller 14 to rotate with the rotative speed of regulation, can textile yarn 10 be pulled out with the speed of regulation from textile apparatus 9 and downstream side carry.In addition, owing to can hold and stay the outer peripheral face of roller 14 to hold to stay textile yarn 10 at yarn temporarily, so, can make yarn hold and stay device 12 to play a role as a kind of apparatus for temporary storage.Thus, can eliminate the inconsistent unfavorable condition of the weaving speed of the textile apparatus 9 causing because of any reason and winding speed (speed of the textile yarn 10 of reeling to package 45) (such as textile yarn 10 lax etc.).
At yarn, hold and stay device 12 downstream to dispose thread guides 58 and wind2 13.Wind2 13 has the reel cage arm 71 that can swingingly support around bolster 73.This reel cage arm 71 can support the spool 48 for the textile yarn 10 of reeling in revolvable mode.
Wind2 13 has: reel spool (contact roller) 72, traverse gear 75.In addition, wind2 13 has the graphic reel spool CD-ROM drive motor of omission.The propulsive effort of reel spool 72 by reel spool CD-ROM drive motor is passed and rotates under the state that contacts at the outer peripheral face with described spool 48 or package 45.In addition, by motor control portion 62, (periodic Control portion, Fig. 3) is controlled reel spool CD-ROM drive motor.Traverse gear 75 has the guiding piece 76 that traverses that can engage with textile yarn 10.Limit makes to traverse guiding piece 76 crank motion limits by omitting graphic electrical motor driven reel spool 72 by omitting graphic driver train, thus, the package 45 contacting with reel spool 72 is rotated, and makes textile yarn 10 traverse and reel.
As shown in Figures 1 and 2, connecing yarn chassis 3 has: connect yarn feeding device 43, suction device (suction pipe 44 and suction nozzle 46).For connecing yarn chassis 3, when there is yarn broken yarn or yarn cut-out in a certain weaving unit 2 after, connect yarn chassis 3 and on track 41, move to this weaving unit 2 and stop.Rotate centered by axle on above-below direction on described suction pipe 44 limits, thereby limit sucks and catches to connecing yarn feeding device 43 guiding the yarn ends of sending from textile apparatus 9.Rotate at above-below direction centered by axle on suction nozzle 46 limits, thereby limit attracts yarn ends and catches to connecing yarn feeding device 43 guiding from the package 45 by described wind2 13 supportings.Connect yarn feeding device 43 carry out directed yarn ends each other connect yarn.
Next, to judging in yarn holds the textile yarn 10 of the upstream side that stays device 12, whether exist abnormal formation to describe.
First relation between winding speed and the tension force of wind2 13 sides is described.In addition, the winding speed in this specification sheets refers to, the speed of the textile yarn 10 before being wound in package 45, be from according to the diameter of the rotative speed of reel spool 72 and package 45 and the different concept of the speed that budgetary estimate is obtained.
In the situation that winding speed is fast, because textile yarn 10 is strongly pulled by wind2 13, so near the tension force of the textile yarn 10 wind2 13 uprises.In the situation that winding speed is slow, because carrying out brute force to textile yarn 10 hardly, wind2 13 pulls, so near the tension force of the textile yarn 10 wind2 13 reduces.
Therefore,, according to the variation of winding speed, can hold the tension change of wind2 13 sides.
Whether the textile yarn 10 that next, yarn is held to the upstream side that stays device 12 described by the impact of the tension change of wind2 13 sides.
As previously mentioned, yarn holds and stays device 12 to play a role as a kind of apparatus for temporary storage.Therefore, at yarn, hold (yarn holds in the sufficient situation of allowance) stay device 12 effectively to play a role in the situation that, the textile yarn 10 that yarn holds the upstream side that stays device 12 is not subject to the impact of the tension change of wind2 13 sides.In this situation, the tension force that textile state detector 52 detects does not occur significantly to change substantially.
On the other hand, as shown in Fig. 4 A and Fig. 4 B, in the situation that yarn holds, to stay the yarn of device 12 to hold allowance less or do not hold allowance, because holding, yarn stay device 12 effectively not play a role, so yarn holds and stays the textile yarn 10 of device 12 upstream sides can be subject to the impact of the tension change of wind2 13 sides.In this situation, the tensiometer that textile state detector 52 detects reveals with the tension change of wind2 13 sides and is similarly inclined to.In addition,, if the tension force of this larger tension force or significantly change is applied on textile yarn 10, there is the possibility that produces abnormal yarn.
In addition, at yarn, hold stay device 12 not have yarn to hold allowance completely in the situation that, the textile yarn 10 that yarn holds the upstream side that stays device 12 is subject to the impact of the tension change of wind2 13 sides really.And hold allowance less in the situation that at yarn, whether be subject to this to affect according to weaving condition etc. is different.For example, in the situation that winding speed is low speed, even hold allowance fewer in the situation that at yarn, be also difficult to be subject to the impact of the tension change of wind2 13 sides.Below, be subject to aspect the effect of tension change of wind2 13 sides, existing yarn is held to the situation that the less state of allowance shows as " yarn holds allowance deficiency " etc.
In sum, in present embodiment, according to the tension change (variation of winding speed) of the tension force of the detection of textile state detector 52 and wind2 13 sides, yarn is held to allowance whether not enough (whether occurring abnormal in textile yarn 10) and judge.Below, be specifically described.
In present embodiment, in order to prevent the generation of aforesaid overlapping coiling, carry out disturbance control (periodic Control).Disturbance in present embodiment is controlled as following and is controlled, thereby 62 pairs of reel spool CD-ROM drive motor of motor control portion are controlled the rotative speed cyclical variation that makes reel spool 72, makes thus winding speed change.
In the situation that controlled the rotative speed of reel spool 72 is accelerated by disturbance, winding speed is also accelerated, and it is large that the tension force of wind2 13 sides becomes.In the situation that controlled the rotative speed of reel spool 72 is slowed down by disturbance, winding speed also slows down, and the tension force of wind2 13 sides diminishes.
At yarn, hold in the inadequate situation of allowance, to follow the mode of controlling the velocity variations of carrying out by disturbance, the tension force change of the detection of textile state detector 52.The passing of holding the tension force that the sufficient state of allowance detects to textile state detector 52 situation of not enough state variation from yarn has been shown in Fig. 5.
Shown in Fig. 5, at yarn, hold in the sufficient situation of allowance, the textile yarn 10 that yarn holds the upstream side that stays device 12 is not subject to the impact of the tension change of wind2 13.Therefore the tension force that, textile state detector 52 detects can significantly not change yet.
In the situation that yarn holds allowance deficiency, the textile yarn 10 that yarn holds the upstream side that stays device 12 is subject to the impact of the tension change of wind2 13.There is significantly change (with reference to Fig. 5) in the tension force that therefore, textile state detector 52 detects.In present embodiment, by acceleration that the rotative speed of reel spool 72 is accelerated being controlled and deceleration that the rotative speed of reel spool 72 slows down being controlled, form 1 cycle that disturbance is controlled.Therefore, when the acceleration that rotative speed is accelerated is controlled, tension force rises, and when the deceleration that rotative speed is slowed down is controlled, tension force declines.
Next, to whether existing extremely, the flow process of the processing that the detection unit 61 of cell controller 60 carries out describes in order to judge in textile yarn 10.Fig. 6 is to whether there is the diagram of circuit of extremely judging in textile yarn 10.In addition, this diagram of circuit is illustration, as long as can bring into play effect of the present invention, can append or delete and process or change the order of processing.
In the situation that the difference that step S101 obtains is more than first threshold, detection unit 61 is judged to be existence abnormal (step S103) in textile yarn 10.In first threshold, be set with the value of the Tension Difference that expression only can produce when textile state detector 52 is subject to the affecting of tension change of wind2 13 sides.In the situation that the difference of obtaining in step S101 is less than first threshold, detection unit 61 carries out ensuing determination processing (step S102).
In step S102, to the difference of the maxim during 1 cycle and minimum value, whether be that the Second Threshold of obtaining in advance judges above.This is owing to considering as shown in Figure 5, when yarn holds allowance deficiency, and the situation that tension force can significantly change.
In the situation that the difference of maxim and minimum value is more than Second Threshold, detection unit 61 is judged to be yarn and holds allowance deficiency (step S103).In Second Threshold, be set with the value of the difference of maxim that expression only can produce when textile state detector 52 is subject to the affecting of tension change of wind2 13 sides and minimum value.In the situation that the difference of obtaining is less than Second Threshold, detection unit 61 is judged to be not abnormal generation in current time textile yarn 10, carries out the processing of step S101 after specified time again.
Like this, in the present embodiment, by two kinds of methods, judge in textile yarn 10 and whether occur extremely.In the method for step S101, though in the situation that yarn holds allowance deficiency, can detect immediately, after being transitioned into yarn and holding the state of allowance deficiency, be difficult to detect whether occur abnormal.In the method for step S102, even also can detect after being transitioned into yarn and holding the state of allowance deficiency, whether occur extremely, but exist, cannot detect immediately the possibility that yarn holds the situation of allowance deficiency.
Therefore, by also, by the method for step S101 and the method for step S102, can judge reliably the abnormal of textile yarn 10.
The in the situation that of in cell controller 60, being judged to be " occurring abnormal in textile yarn 10 " at detection unit 61, this situation is informed to user (step S104).In present embodiment, produce alarm sound and this situation is presented in monitoring device 91.In addition, inform that mechanism is not limited to this, can also be presented in the monitoring device (omitting diagram) being arranged on each weaving unit 2, and by making to be located at luminous the informing such as lamp on each weaving unit 2.In addition, for monitoring device 91 etc., can also replace above-mentioned or append the situation of informing " yarn holds and stays the yarn of device 12 to hold allowance deficiency ".
The textile yarn 10 in the downstream at cut position is wound in package 45 temporarily.In addition, be wound onto at this moment in the textile yarn 10 in package 45 and include abnormal yarn.Therefore, cell controller 60 stops drafting assembly 7, and makes the coiling in wind2 13 also stop (step S105).
Next, cell controller 60 transmits control signal to connecing yarn chassis 3, and before moving it the abnormal weaving unit 2 that detects textile yarn 10, indication connects yarn action (step S106).Connect yarn chassis 3 and receive this indication, by suction pipe 44 and the yarn ends of 46 pairs of textile apparatus 9 sides of suction nozzle and the yarn ends of package 45 sides, attract to catch.Now, the abnormal position being wound in package 45 is attracted and is pulled out by suction nozzle 46.Thus, the abnormal position of detecting is removed.Next, the yarn ends that suction pipe 44 and suction nozzle 46 will attract catch is to connecing yarn feeding device 43 guiding, at this, connects and in yarn feeding device 43, connects yarn action.
By the above yarn that connects, move, remove abnormal yarn, can again start textile yarn 10 to the coiling (step S107) of package 45.In addition, cell controller 60, after again starting the coiling of textile yarn 10, carries out the processing shown in the diagram of circuit of Fig. 5 again, judges the abnormal of textile yarn 10.
As described above, the spinning frame 1 of present embodiment has: textile apparatus 9, textile state detector 52, yarn hold and stay device 12, wind2 13, detection unit 61.Textile apparatus 9 is supplied with textile yarn 10.Textile state detector 52 is configured in the downstream of textile apparatus 9, detects the tension force of textile yarn 10.Yarn holds and stays device 12 to be configured in textile state detector 52 downstream, and textile yarn 10 is held and stayed temporarily.Wind2 13 is configured in yarn and holds and stay device 12 downstream, and textile yarn 10 is wound in package 45.The yarn that detection unit 61 detects according to textile state detector 52 holds the tension force of the upstream side that stays device 12 and the variation of winding speed extremely judging textile yarn 10.
Thus, the correlativity of the tension force that the tension change of wind2 13 sides that cause according to the variation by winding speed and textile state detector 52 detect, can hold the tension change that stays device 12 whether can absorb wind2 13 sides to yarn and hold.Therefore, can accurately judge in textile yarn 10 and whether exist extremely.
In addition, the spinning frame 1 of present embodiment has the reel spool 72 that contacts and be rotated with package 45.The rotative speed of the tension force that detection unit 61 detects according to textile state detector 52 and reel spool 72, to extremely judging of textile yarn 10.
Thus, can infer the variation that winding speed from the variation of the rotative speed of reel spool 72, so, can change and judge the abnormal of textile yarn 10 according to this.
In addition, in the spinning frame 1 of present embodiment, the tension force before 1 cycle that the tension force that 61 pairs of textile state detectors 52 of detection unit detect and disturbance are controlled compares, and according to this comparative result, judges the abnormal of textile yarn 10.
Thus, can detect yarn and hold the situation of staying device 12 cannot absorb the tension change of wind2 13 sides, so, can detect rapidly abnormal situation occurs in textile yarn 10.
In addition, in the spinning frame 1 of present embodiment, the maxim of the tension force that during at least 1 cycle that detection unit 61 is controlled according to disturbance, textile state detector 52 detects and minimum value poor, judges the abnormal of textile yarn 10.
Thus, can detect reliably impact that disturbance controls and show that yarn holds the situation on the tension force of the upstream side that stays device 12, can judge the abnormal of textile yarn 10.Therefore,, even in the situation that yarn for example cannot be detected and hold and stay device 12 can not absorb moment of the tension change of wind2 13 sides, also can judge the abnormal of textile yarn 10.
More than illustrated preferred embodiment of the present inventionly, but above-mentioned formation can change in for example following mode.
In above-mentioned embodiment, by making the rotative speed of reel spool 72 change to carry out disturbance control, but replace which, can also make the velocity variations carry out disturbance control of traversing of traverse gear 75.In addition, in the situation that there is the formation of the motor of direct driving package 45, can also be by making the rotative speed of this motor change to carry out disturbance control.In this situation, according to the rotative speed of motor (rotative speed of package 45), can judge the abnormal of textile yarn 10.
In above-mentioned embodiment, detection unit 61 is judged according to the variation of the winding speed in disturbance control, but replacement which can also be judged according to following value.That is, for example, in the situation that to taper winding, package is reeled, if make the rotative speed of reel spool 72 constant,, when textile yarn 10 is wound on to large footpath side and when textile yarn 10 is wound on to path side, winding speed is different.Detection unit 61 it is also conceivable that this point judges.
Yarn being held to the test section that the tension force of the upstream side that stays device 12 detects, be not limited to the example shown in above-mentioned embodiment, can also be example formation as Patent Document 1.
