Description
Technical field
The present invention relates to filament winding device and possess the spinning draw-gear of this filament winding device.
Background technology
Patent Document 1 discloses and be wound up into from device for spinning spun multi-filament line the up-coiler that bobbin forms multiple package respectively.This up-coiler possesses: the traversing gear making the respectively traversing of multi-filament line, is horizontally supported on turntable with cantilever position, installs the coil holder of multiple bobbin, and with the contact roller of coil holder configured in parallel.From device for spinning spun multi-filament line limit by traversing gear traversing, limit is wound up on multiple bobbins of being arranged on coil holder respectively, by forming multiple package like this.And, in the process forming package, contact roller all the time with the surface contact of multiple package, pay predetermined contact to respectively multiple package, rotate with the superficial velocity roughly the same with the superficial velocity of package simultaneously, pass out to package by by the silk thread of traversing gear traversing.
But, along with Filament winding on multiple bobbins of coil holder, multiple package reels respectively and increases thick, coil holder bends downward under the weight effect of multiple package.If the cantilevered support structure that patent document 1 is such, then the part the closer to coil holder top more leaves the ground displacement downward of contact roller.Thus, bobbin is larger with the top of the distance contacted between roller more toward coil holder, and therefore, be more wound up into the package on the bobbin on coil holder top, winding diameter is larger, and the winding diameter the closer to the package of rear end is less.Wherein, due to all packages be wound up on the multiple bobbins be arranged on same coil holder, rotating speed is all identical, therefore the package speed of the side, rear end that the speed that is wound of the silk thread of the side, top that winding diameter is large is less than winding diameter is fast.Therefore the tension force becoming the silk thread be wound up in package is more larger toward side, top, more toward the state that side, rear end is less.
Due to the difference of this winding tension, create the shape of wound package, the uneven of case hardness, produce the problems such as the winding attitude variation of the package such as the shape of a saddle, bulge.And the package contact being positioned at side, coil holder top is low, the package contact of side, rear end uprises.Thus, the rare close inequality (yarn posts り) of silk thread that contact disappears in the winding process that causes is produced when being equipped with of side, top.Further, the silk thread damage that the package in side, rear end causes due to high contact, becomes the reason of the uneven dyeing in subsequent handling, silk thread quality abnormal sometimes.
For this point, the winding that the up-coiler of patent document 1 possesses along with multiple package increases the leaning device slightly making contact roller automatically tilt.First, the winding diameter along with package becomes large, turntable is rotated, makes coil holder leave contact roller.Now, the contact leaning device of roller and the rotation linkage action of turntable, make contact roller tilt.Thus, contacting roller takes to make its top ends along the flexing displacement of coil holder to the inclination attitude of below.
Also the up-coiler that can solve the problem is disclosed in patent document 2.But patent document 1 is above the technology increasing thick mechanically interlock with the winding of package, make to contact roller wing drop, but this patent document 2 is at the degree of flexibility first inferring coil holder, according to different in the inclination this point of this estimation result control contact roller.
The up-coiler of patent document 2 possesses 2 fluid pressure cylinders at the both ends of bearing contact roller respectively.Further, the relational expression between weight of package and the deflection degree of coil holder is stored in storage part.Further, in winding process, control device uses the information such as the spray volume of device for spinning (weight of the polymer exported in time per unit) to be obtained the weight of package by computing.Further, the weight of package of trying to achieve and the relational expression of above-mentioned deflection degree is used to calculate pressure set points for making to contact 2 fluid pressure cylinders that roller tilts respectively.Then, by making the pressure of the fluid provided to 2 fluid pressure cylinders control respectively with becoming above-mentioned pressure set points, contact roller tilts accordingly with the deflection of coil holder.
[patent document 1] Japanese Unexamined Patent Publication 2011-255979 publication
[patent document 2] Japanese Unexamined Patent Publication 2001-48422 publication
Increase thick interlock with the winding of package adopting as patent document 1, when the structure utilizing leaning device to make contact roller tilt, if the formation condition of package is identical no problem all the time, but when this condition has changed, be difficult to deal with.Such as, if be wound up into the kind change of the silk thread in package, then the rolling density change of package.Be exemplified as, when PET silk, rolling density is 0.9 ~ 1.0g/cm
3, when nylon yarn, be 0.7 ~ 0.8g/cm
3left and right, when being called as the carpet precursor of Nylon BCF, rolling density is less than 0.5g/cm
3.Like this, even if the weight of package is identical in the different package of rolling density, the diameter of package is also different, even if or the diameter of package identical, weight is also different.Like this, if because the kind of silk thread changes, then the weight of package and the relation of winding diameter change, therefore in order to pay suitable contact to package, originally the difference according to silk thread kind is needed, change identical winding diameter---i.e. the angle of inclination of the contact roller at the same position place of turntable, but change such in the structure of patent document 1 is difficult to.
Further, as the other example changing package formation condition, having is not that whole positions at the installation bobbin of coil holder form package, and on the portion of coil holder, only form the situation of package.Such as, in order to reach the object of silk thread of more than the maximum fan-out capability of producing device for spinning, sometimes on the way by from each more than 2 doublings in device for spinning spun multi-filament line, become 1 Filament winding in package.In this case, and to reel respectively from compared with the situation of the spun multi-filament line of device for spinning, the number being formed in the package on coil holder reduces.That is, due to forming position, the gross weight change of package, the deflection of coil holder when therefore the winding diameter of package is identical also changes.But, in the structure of patent document 1 when the deflection of coil holder has changed, be difficult to the corresponding angle of inclination changing contact roller.
In contrast, patent document 2 is the gross weight obtaining package according to information such as the spray volumes of polymer, the structure that the deflection degree of prediction coil holder makes contact roller tilt.Even if this structure also can obtain the gross weight of package, therefore, it is possible to predict the deflection degree of coil holder exactly due to the rolling density change of package.But the device of this patent document 2 only imagines the situation forming package at whole winding positions of coil holder respectively.Namely, when only forming package on the portion of coil holder, the deflection degree of coil holder can not be predicted exactly.

The side view of spinning draw-gear when Fig. 3 is doubling winding.In addition, for the ease of the following description in Fig. 3, for 8 corresponding with 8 bobbin installation portions 30 of coil holder 22 respectively Tiao Si roads, the numbering of additional No.1 ~ No.8 from side, top.In the example of Fig. 3, the 2 rhizoid line Y1s (of the present invention 1st thread) corresponding with No.1 with the No.2 horn pipe installation portion 30 in Fig. 1 are become 1 rhizoid line Y2 (2nd of the present invention) by cross winding, doubling in interleaver 6, and the silk thread Y2 after doubling is wound up on the bobbin B that is arranged on No.1 horn pipe installation portion 30.Equally, this 2 rhizoid line of No.3 and No.4 Y1 doubling, reels at No.3 horn pipe installation portion 30 place, this 2 rhizoid line of No.5 and No.6 Y1 doubling, at No.5 horn pipe installation portion 30 place winding, this 2 rhizoid line of No.7 and No.8 Y1 doubling, reels at No.7 horn pipe installation portion 30 place.
By the silk thread Y1 from spun more than 2 of device for spinning 2 in midway doubling, the radical of the silk thread Y2 after the doubling of coiler device 7 place winding is fewer than the radical of the silk thread Y1 before doubling.Therefore, when doubling reels, in 8 bobbin installation portions 30 of coil holder 22, only have part bobbin installation portion 30 to reel silk thread Y2.Such as, in Fig. 3 No.1,3,5,7 odd number bobbin installation portions 30 form 4 package P.In addition, Fig. 3 is example after all, can suitably change for how many rhizoid line Y1 doubling or which position of the silk thread Y2 after doubling being wound on coil holder 22 are formed package P etc.
Such as, both 4 package P can be formed on No.1 ~ 4 of the side, deflection top of coil holder 22, also 4 package P can be formed conversely on No.5 ~ 8 of the deflection radicle side of coil holder 22.In addition, although illustrate bobbin B in Fig. 3 to be arranged on the form comprising and not having on all bobbin installation portions 30 of the bobbin installation portion 30 of wound package P, bobbin B also can only be arranged on the part bobbin installation portion 30 of formation package P.
When carrying out doubling winding, operating personnel, except set the silk kind of doubling winding from the configuration part 40 of control device 8 except, also set the position (the actual forming position of package) of the actual formation package P of coil holder 22.Such as, as the actual forming position of package set in the example in figure 3 No.1,3,5,7 horn pipe installation portions 30.Then, will from device for spinning 2 spun multi-filament line Y (Y1) repiece to spinning draw-gear 1, but now coiler device 7 only repiece on the silk road corresponding with the actual forming position of the package just now set.Such as, if the example of Fig. 3, repiece to respectively with No.1,3,5, the corresponding fulcrum guide 35 of 7 horn pipe installation portions 30, on traverse motion threadguide 27a.
Wherein, corresponding with the bobbin installation portion 30 not forming package P silk thread detecting sensor 36 can't detect silk thread Y2 certainly.But, if start the winding of package P like this, then according to the signal not having silk thread from this silk thread detecting sensor 36, originally do not produce fracture of wire, but multi-filament line Y1 has been cut off by the careless action of cutter 11.Therefore, when exporting from the silk thread detecting sensor 36 corresponding with the bobbin installation portion 30 not forming package P the signal not having silk thread, first winding control portion 41 utilizes the alarm lamp, alarm etc. be arranged on control device 8, control panel 28 to give a warning, or display error messages etc. in the display in configuration part 40 etc., alert operator detects the state not having silk thread.In order to carry out doubling winding, in confirmation, this does not have the no problem rear releasing warning of the signal of silk thread to operating personnel.
In addition, mistake from the setting of the actual forming position of the package of configuration part 40 due to operating personnel or be suspended to Cuo Si road by silk thread Y when coiler device 7 repiece, the position of the actual forming position of the package set by configuration part 40 and actual hook silk thread Y is sometimes inconsistent.In this case, the actual situation defining package P on the bobbin installation portion 30 that configuration part 40 is set as not formed package P may be had.But the actual forming position of package that configuration part 40 is set by winding control portion 41 by this mistake contrasts with the Output rusults of multiple silk thread detecting sensor 36, can know in advance.Namely, the silk thread detecting sensor 36 corresponding with the bobbin installation portion 30 being set as not formed package P should can't detect the silk thread Y2 of walking originally, but when outputing silk thread detection signal from this silk thread detecting sensor 36, the setting mistake or the repiece mistake that there is the actual forming position of package can be judged to be.In this case, first winding control portion 41 uses the alarm lamp be arranged in coiler device 7, control device 8, control panel 28, the display etc. of alarm or configuration part 40 warns.By this warning recognize the operating personnel of mistake to change from configuration part 40 the actual forming position of package information or according to setting again repiece to meet the testing result of silk thread detecting sensor 36.
(coil holder and the correction of the depth of parallelism contacting roller)
Then, illustrate and to increase slightly corresponding coil holder 22 and the correction of the depth of parallelism contacting roller 26 with the winding of the package P be formed on coil holder 22.Fig. 4 is the figure of the flexure that the coil holder 22 that package P causes is described.Coil holder 22 and being summarized as follows of correction of the depth of parallelism contacting roller 26.
As shown in double dot dash line in Fig. 4, increase owing to increasing the weight slightly brought along with the winding of package P, coil holder 22 bends below.If in contrast, contact roller 26 also poor words, be then arranged between the multiple bobbin B on coil holder 22, different with the distance contacted between roller 26.Thus, the winding diameter being wound on the package P on the bobbin B of the side, top of coil holder 22 becomes large, otherwise the winding diameter of the package P of radicle side diminishes.Therefore, be necessary the posture changing contact roller 26 according to the deflection degree of coil holder 22, make coil holder 22 as far as possible and contact roller 26 and connect subparallel state.
The deflection of coil holder 22 can be calculated by the Flexurally rigid EI of coil holder 22, the weight W of position and each package that forms package P.Therefore, in present embodiment, inferring the variable quantity of the flexure of the coil holder 22 produced because forming package P from the weight W of package P etc., according to this guess value, contact roller 26 being tilted along the flexure of coil holder 22, carry out coil holder 22 and the correction of the depth of parallelism contacting roller 26.
Fig. 5 is coil holder 22 (package P) and the flow chart of depth of parallelism correction contacting roller 26.Referring to Fig. 4 with Fig. 5, package P and the details of depth of parallelism correction contacting roller 26 are described.In addition, the correction of this depth of parallelism performs together with starting the winding of package P, until winding terminates repeatedly to carry out.
A first () calculate the weight of package P, in order to calculate the flexure variable quantity of coil holder 22, calculate the weight Wn (n is the numbering of bobbin installation portion 30) (S1) of package P.The weight Wn of this package P can from the fiber number of winding speed, silk thread Y and from winding rear elapsed time calculate.Or, can from the spray volume of the polymer of device for spinning 2 and from reel after elapsed time calculate the weight Wn of package P.Or, can also calculate from the winding diameter of package P and traversing width, rolling density.In this case, the winding diameter of package P can be obtained from the diameter of the rotating speed of the rotating speed of such as coil holder 22, contact roller 26 and contact roller 26.Further, rolling density is set from configuration part 40 by operating personnel according to silk kind.In addition, due to the not too large difference of weight of multiple package P, can not be also therefore the weight Wn individually calculating all package P in the S1 of Fig. 5, but only calculate the weight of a package P, the weight of other package P be regarded as identical with it.
B () infers the flexure variable quantity of coil holder 22 then, winding control portion 41 infers that the winding because of each package P increases the flexure variation delta δ (S2) of the thick coil holder 22 produced.
Before the above-mentioned flexure variation delta δ of explanation, first define the deflection δ of coil holder 22." the deflection δ of coil holder 22 " defines with (being positioned at bobbin installation portion 30 displacement downwards of top side)-bobbin installation portion 30 displacement downwards of butt side (be positioned at most).As in Fig. 4 with shown in double dot dash line, if more in the form that side, the top displacement of coil holder 22 is larger, then for the displacement of No.1 horn pipe installation portion 30 deducts the difference of the displacement of No.8 horn pipe installation portion 30.
In addition, although the top ends that Fig. 4 illustrates coil holder 22 is displaced to than radicle form on the lower, the change form of coil holder 22 is not limited to the form of Fig. 4.Such as, when multiple package P is formed in the deflection radicle side of coil holder 22, the radicle of coil holder 22 is displaced to than top ends on the lower.That is, coil holder 22 is different according to the forming position of package P, not only has top ends than radicle situation on the lower, also has radicle than top ends situation on the lower.Further, when multiple package P is formed in the side, deflection top of coil holder 22, the not only top ends of coil holder 22 displacement widely downwards, and also the part of likely radicle side is conversely to top offset.
Further, even if when not forming package P, coil holder 22 also may produce initial deflection because its deadweight waits.So the deflection δ of coil holder 22 is relative to the variable quantity of above-mentioned initial deflection when " the flexure variation delta δ of coil holder 22 " in present embodiment means to form package P.
In order to infer the flexure variable quantity of this coil holder 22, when each bobbin installation portion 30 for coil holder 22 only acts on this bobbin installation portion 30 by the load that Unit Weight is obtained in experimental analysis in advance or computational analysis, the flexure variable quantity (unit flexure variation delta δ n (n is the numbering of bobbin installation portion 30)) of coil holder 22, is then stored in the storage part 42 of control panel 28.
And, winding control portion 41 reads the information of the actual forming position of package from storage part 42, and the information of the weight Wn of the package P calculated from the actual forming position of this package, S1 and above-mentioned unit flexure variation delta δ n infers the flexure variation delta δ of coil holder 22.
Be specially, for a bobbin installation portion 30, can obtain by weight of package Wn being multiplied by unit flexure variation delta δ n the flexure variation delta δ np (hereinafter referred to as " single flexure variable quantity ") only forming coil holder 22 when weight is the package P of Wn at this 1 bobbin installation portion 30.Therefore, in order to calculate the flexure variation delta δ of actual coil holder 22, as long as the summation whole bobbin installation portions 30 forming package P being obtained to above-mentioned single flexure variation delta δ np is just passable.
Such as, when forming package P as shown in FIG. 1 on whole bobbin installation portions 30 of coil holder 22,
Flexure variation delta δ=Δ δ 1p+ Δ δ 2p+ Δ δ 3p+ Δ δ 4p+ Δ δ 5p+ Δ δ 6p+ Δ δ 7p+ Δ δ 8p=(Δ δ 1W1)+(Δ δ 2W2)+(Δ δ 3W3)+(Δ δ 4W4)+(Δ δ 5W5)+(Δ δ 6W6)+(Δ δ 7W7)+(the Δ δ 8W8) of coil holder 22.
On the other hand, when the winding of doubling as shown in FIG. 3 only No.1,3,5,7 these 4 bobbin installation portions 30 form package P,
Flexure variation delta δ=Δ δ 1p+ Δ δ 3p+ Δ δ 5p+ Δ δ 7p=(Δ δ 1W1)+(Δ δ 3W3)+(Δ δ 5W5)+(the Δ δ 7W7) of coil holder 22.
Wherein, even the state not forming package P due to coil holder 22 under its effect of conducting oneself with dignity also bends, and due to the machining accuracy of each several part, coil holder 22, contact roller 26 by supporting a little obliquely etc., even if therefore coil holder 22 with contact relation that roller 26 not have under the state of wound package P both on coil holder 22 also with some deviation of completely parallel state.Therefore, under the state that coil holder 22 is not formed package P, in order to make coil holder 22 and the state contacting roller 26 and become parallel, carry out the mechanicalness adjustment employing suitable mechanism.
C () calculates the pressure of the fluid provided to fluid pressure cylinder 24,25 then, winding control portion 41, in order to make to contact roller 26 tilt with the deflection degree of coil holder 22 be corresponding, calculates the pressure differential Δ P (S3) of 2 fluid pressure cylinders 24,25.Be specially, be previously stored with in storage part 42 and analyze by experiment or the pressure differential of expression 2 fluid pressure cylinders 24,25 that computational analysis is tried to achieve and the data of relation of gradient contacting roller 26.In addition, first winding control portion 41 infers from S2 that the flexure variable quantity of the coil holder 22 calculates the target tilt angle of contact roller 26.Then, the pressure differential obtaining 2 fluid pressure cylinders 24,25 according to the data be stored in storage part 42 becomes above-mentioned target tilt angle to make the angle of inclination of this contact roller 26.
In addition, necessarily above-mentioned (a) is not calculated the weight of package P, (b) infer the flexure variable quantity of coil holder 22, (c) calculate fluid pressure and be divided into 3 such stages and calculate successively.Such as, the form that the pressure differential Δ P of 2 fluid pressure cylinders 24,25 bends the function of variation delta δ n with the unit of the weight W and coil holder 22 with package P is stored in storage part 42.In this case, above-mentioned function can be used and once calculate pressure differential Δ P about the information of silk kind, the information etc. of the actual forming position of package.
The correction of (d) depth of parallelism then, winding control portion 41 make the difference of the fluid pressure being supplied to 2 fluid pressure cylinders 24,25 be the pressure differential Δ P obtained in S3 control fluid supply unit 34.Thus, make to contact roller 26 substantially in parallel with coil holder 22 to tilt.In addition, although speak of the initial deflection degree of the coil holder caused by conduct oneself with dignity etc. when eliminating do not form package P by mechanicalness adjustment in previous explanation, mismachining tolerance cause and coil holder 22 and the situation of deviation of parastate contacting roller 26, but may not be mechanicalness adjustment, but carry out the above-mentioned deviation of adjustment elimination by the fluid pressure differential of 2 fluid pressure cylinders 24,25.In this case, the pressure differential Δ P of 2 fluid pressure cylinders 24,25 is set as the aggregate value being used for carrying out the pressure differential Δ P2 tried to achieve in pressure differential Δ P1 and S3 of the depth of parallelism correction when not having package P.
Wound package P from this coil holder 22 is until terminate the process that (being "Yes" in S5) carries out above-mentioned S1 ~ S4 repeatedly.
According to the present embodiment illustrated above, following action effect can be obtained.
Coiler device 7 forms package P by making coil holder 22 rotate by Filament winding to the bobbin B on the bobbin installation portion 30 being arranged on coil holder 22.Forming the midway of this package P, the winding along with package P increases thick, and coil holder 22 bends.So the flexure variable quantity of coil holder 22 is inferred in winding control portion 41, the flexure variable quantity gone out by inference carries out coil holder 22 and the correction of the depth of parallelism contacting roller 26.By maintaining coil holder 22 and the parastate contacting roller 26, the winding diameter of whole package P can be made even.Thereby, it is possible to alleviate the uneven of each package winding tension, and pay uniform contact can to each package P.
And winding control portion 41 obtains the position (the actual forming position of package) of the bobbin installation portion 30 of actual formation package P, the information of the actual forming position of this package is used to infer the flexure variable quantity of coil holder 22.Thus, even if when only forming package P like this on the portion of coil holder 22 when doubling reels, this precision of information also can be used to infer the flexure variable quantity of coil holder 22 well.
Further, for each bobbin installation portion 30 of coil holder 22, the flexure variable quantity (unit flexure variation delta δ n) only forming coil holder 22 during package P on this bobbin installation portion 30 is stored in the storage part 42 of control panel 28.Therefore, reality is formed to the bobbin installation portion 30 of package P, can bend from unit the single flexure variation delta δ np that variation delta δ n and weight of package Wn infers the only coil holder 22 when each bobbin installation portion 30 forms package P.Further, by obtaining the summation of the single flexure variation delta δ np of the bobbin installation portion 30 of actual formation package P, the flexure variation delta δ of actual coil holder 22 can be inferred.
Wherein, forming package P on which position of coil holder 22, there is various form in the using method etc. according to this device.But, present embodiment is stored in storage part 42 owing in advance unit being bent variation delta δ n for each in multiple bobbin installation portion 30, when therefore no matter forming package P on which position of coil holder 22, the unit corresponding with the actual forming position of this package can both be used to bend flexure variable quantity that variable quantity obtains coil holder 22 simply.
Then, the change form above-mentioned embodiment being applied with to all changes is described.But have mutually isostructural part for above-mentioned embodiment, suitably the description thereof will be omitted to add identical mark.
1), in above-mentioned embodiment, 1 bobbin installation portion 30 of coil holder 22 be assume that the flexure variable quantity (unit flexure variation delta δ n) of the coil holder 22 when only forming the load of Unit Weight on this bobbin installation portion 30 is pre-stored in storage part 42.So, coil holder 22 is formed multiple package P, calculated the flexure variable quantity of coil holder 22 by the summation of the unit flexure variation delta δ n obtaining them.Relative to this, may not be the flexure of bobbin installation portion 30 storage cell one by one variation delta δ n, but by each about the actual form forming the position of package P, the unit of coil holder 22 flexure variation delta δ n sum is stored in storage part 42.
Such as, as shown in Figure 3, can be set in from the configuration part 40 of control panel 28 No.1 of coil holder 22,3,5,7 horn pipe installation portions 30 form the form of package P (for convenience of explanation, be called the 1st form) and in contrast at No.2,4,6,8 horn pipe installation portions 30 are formed the form (being called the 2nd form) of package P.In addition, the 1st form and the 2nd form phase in this embodiment. when the information in the actual forming position of package of the present invention.
Further, store in storage part 42 with unit flexure variation delta δ n sum Δ δ a when the 1st form formation package P with unit flexure variation delta δ n sum Δ δ b when the 2nd form formation package P.That is,
Δ δ a (the 1st form)=Δ δ 1+ Δ δ 3+ Δ δ 5+ Δ δ 7
Δ δ b (the 2nd form)=Δ δ 2+ Δ δ 4+ Δ δ 6+ Δ δ 8.
And, when doubling reels, when to set a form in the 1st form and the 2nd form with configuration part 40 as operating personnel, the flexure variation delta δ a (Δ δ b) under the form that winding control portion 41 uses this to select infers the flexure variation delta δ of coil holder 22.When the 1st form, Δ δ=mW Δ δ a.When the 2nd form, Δ δ=mW Δ δ b (m is the number of the package P be formed on a coil holder 22).
In which, have and need the advantage that the data volume of the relevant flexure variable quantity be stored in storage part 42 less just can be such.Be particularly useful for roughly determining that when doubling reels which position at coil holder 22 forms the situation of package P.
2) structure of posture being used for changing contact roller 26 is not limited to the structure of above-mentioned embodiment, can carry out illustrating such change below.
A () is used for the structure of bearing contact roller 26 and can suitably changes.For the roller support unit 37 of rotatably bearing contact roller 26 can incline pendulum or be translationally arranged on supporting frame 23 in Fig. 1, Fig. 3 of above-mentioned embodiment, and the structure that the posture of this roller support unit 37 is changed by 2 fluid pressure cylinders 24,25.In contrast, also can be omit supporting frame 23 as shown in FIG. 6, roller support unit 37 be slidably arranged on the structure on body 20 with not shown linear motion bearing parts etc.
In (b) above-mentioned embodiment, 2 fluid pressure cylinders 24,25 are utilized to carry out paying contact and correction coil holder 22 and both the depth of parallelisms contacting roller 26 to package P.In contrast, also can carry out the correction of the above-mentioned depth of parallelism by the structure different from the structure of paying contact to package P.Such as, one or more pressure cylinders etc. also can be used to make the roller support unit 37 of bearing contact roller 26 or supporting frame 23 bend along coil holder 22 forcibly, revise coil holder 22 and the depth of parallelism contacting roller 26.And, when having that restrict rollers support unit 37 slides relative to supporting frame 23, the parts of rotational action (diagram is omitted), also can utilize that pressure cylinder etc. makes the gradient of these parts forcibly, position is moved, by adjusting the gradient of contact roller 26 like this.
C () above-mentioned embodiment is that contact roller 26 increases with the winding of package P and slightly rises relative to supporting frame 23 accordingly, leave the structure of coil holder 22, but be not limited to such structure.Such as, also can adopt and make by making turntable 21 rotate coil holder 22 leave the structure of contact roller 26 as above-mentioned patent document 1 (Japanese Unexamined Patent Publication 2011-255979 publication) is disclosed.
3), generally, when there is the rotating object of constant weight, the power (one of inertia force) of rotation under acting on the state keeping the direction of rotating shaft on the object, is maintained.This situation is commonly referred to as gyroscopic effect.This phenomenon also produces in the coil holder 22 forming package P.When being formed with coil holder 22 High Rotation Speed of the package P with constant weight, due to above-mentioned gyroscopic effect, coil holder 22 acts on power rotating shaft being kept horizontal direction.Thus, the top ends of the coil holder 22 in rotation is from above-below direction, and the weight overcoming package P upwards lifts ground displacement, and correspondingly, the flexure change amount of coil holder 22 diminishes.
Therefore, when the flexure variable quantity inferring coil holder 22, the displacement Δ δ j of the coil holder 22 that the gyroscopic effect in rotating produces, except the static state flexure variation delta δ s inferring the coil holder 22 produced by the weight of package P, also infers in winding control portion 41.Now, calculate with the flexure variation delta δ=Δ δ s-δ j rotating middle bobbin support 22.Like this, by except the static state flexure variation delta δ s except inferring coil holder 22, also inferring the displacement Δ δ j of the coil holder 22 that gyroscopic effect causes, the flexure variation delta δ of the coil holder 22 in rotation can be inferred thus more accurately.
4) in above-mentioned embodiment, adopt the structure that the actual forming position of package during doubling winding is set from configuration part 40 by operating personnel, but in this case as spoken of in previous explanation, exist and produce the worry that operating personnel set mistake.
Therefore, may not be operating personnel and set the actual forming position of package, but winding control portion automatically obtains the actual forming position of package according to the testing result of multiple silk thread detecting sensors 36 corresponding with multiple bobbin installation portion 30 respectively.In this case, after operating personnel carry out repiece in pair silk road corresponding with the part bobbin installation portion 30 of coil holder 22, coiler device 7 is made to start the silk thread Y that reels.After just starting this winding, walking the silk road corresponding with which bobbin installation portion 30 from the testing result identification silk thread Y of all silk thread detecting sensors 36 in winding control portion 41, is stored in storage part 42 by the bobbin installation portion 30 corresponding with the silk road of silk thread Y being detected as the actual forming position of package.In addition, after the actual forming position of this package of acquisition, being only judged to create fracture of wire when outputing from the silk thread detecting sensor 36 corresponding with the actual forming position of package the signal not having silk thread, cutting off with cutter 11.That is, the signal of the silk thread detecting sensor 36 beyond from the actual forming position of package is ignored.
Like this, owing to using the testing result of silk thread detecting sensor 36 to obtain the actual forming position of package, even if therefore when operating personnel have mistaken the silk road of repiece, the position of actual formation package P can also correctly be obtained.
5) the spinning draw-gear 1 of above-mentioned embodiment is at the device carrying out the production FDY reeled after the spun silk thread Y of device for spinning 2 with coiler device 7 that stretches with extension section 3, but also can apply the present invention to not add hot-stretch from the device of production POY of the spun silk thread Y of device for spinning 2 with regard to carrying out reeling with coiler device 7.The extension section 3 comprising warm-up mill is not needed in the device of this POY.
6) in order to carry out the maintenance of coiler device 7, wish that structure is, by switch etc. operate in the state in fact not having wound package P under change the depth of parallelism.Be specially, wish the operation by carrying out switch etc. to the coiler device 7 stopped, carry out revising coil holder 22 when package P becomes full volume and the action of the depth of parallelism contacting roller 26 under conditions set, thus carry out the maintenance of the depth of parallelism corrective action of coiler device 7.
