Built-in bearing 26 and DD motor 51 in the injection nozzle carrier 24, said bearing 26 rotatably support auxiliary jets 22, said DD motor 51 rotates auxiliary jet 22 as drive source.Bearing 26 disposes at the inside and the auxiliary jet 22 of injection nozzle carrier 24 with one heart, and interior wheel is assembled un-rotatably with respect to auxiliary jet 22, and foreign steamer is assembled un-rotatably with respect to injection nozzle carrier 24.
DD motor 51 is made up of stator 51a and rotor 51b, and said stator 51a disposes at the inside and the auxiliary jet 22 of injection nozzle carrier 24 with one heart, and is assembled un-rotatably with respect to injection nozzle carrier 24 at outer peripheral face; The inner peripheral surface subtend ground of said rotor 51b and rotor 51a is provided with, and is fixed on the outer peripheral face of auxiliary jet 22.Therefore,, auxiliary jet 22 is rotated with rotor 51b, and air jet 22a is rotated around the axis of auxiliary jet 22, the spray angle position of change auxiliary jet 22 with this through making rotor 51b rotating drive.Each DD motor 51 is connected with auxiliary jet control device 61a, from auxiliary jet control device 61a stator 51a is supplied with exciting current, makes each DD motor 51 be rotated driving.
Auxiliary jet control device 61a is made up of driving governor 62 and setting apparatus 63.Setting apparatus 63 is set display unit 46 with input and can be connected communicatedly.In setting apparatus 63, be set with database, this database is about being transfused to the spray angle position of each auxiliary jet group of setting through the input operation of setting display unit 46 in this input, setting display unit 46 from input and passed on.In this database, be set with the spray angle position (specifically, the spray angle position of the auxiliary jet 22 that comprised of each auxiliary jet group of 1 unit of adjustment) of each auxiliary jet group with the form of corresponding weft yarn kind (weft yarn a, weft yarn b's is various).
Promptly in this database; For example be set with following form: the corresponding weft yarn a of difference, b; When being weft yarn a by the weft yarn kind of wefting insertion, the spray angle position θ of each auxiliary jet group is made as, auxiliary jet group G1: θ=x1 °, auxiliary jet group G2: θ=x2 °, auxiliary jet group G3: θ=x3 ° ... When being weft yarn b by the weft yarn kind of wefting insertion, auxiliary jet group G1: θ=y1 °, auxiliary jet group G2: θ=y2 °, auxiliary jet group G3: θ=y3 ° ...
Driving governor 62 can be connected with setting apparatus 63 communicatedly, and selects signal generation 45 to be connected communicatedly with the weft yarn of Weft insertion controller 43.Be connected with DD motor 51 at driving governor 62.In weaving, select signal generation 45 to select signal S1 also to be imported into the driving governor 62 from weft yarn at the weft yarn of each weave cycle output in order to change by the weft yarn of wefting insertion.With this, driving governor 62 reads the setting value of selecting the corresponding spray angle position of signal S1 with the weft yarn of selecting signal generation 45 from weft yarn from the database that is set in setting apparatus 63.Then, driving governor 62 is supplied with exciting current according to the setting value that reads from setting apparatus 63 to DD motor 51, drives DD motor 51.
The method that the regulator of the spray angle position of above-mentioned auxiliary jet 22 adopts following step to constitute is adjusted the spray angle position of auxiliary jet 22.
(1) weaving the preparatory stage, setting the database that 46 pairs of setting apparatus of display unit 63 are set foregoing by input.
(2) weave; Weft yarn select signal generation 45 based on from the anglec of rotation of the main shaft 41 of encoder 42 (below; Be called " degree in crank angle ") signal, according to the weft yarn preference pattern of setting, weft yarn is selected signal S1 output in the wefting insertion control part 44 at each weave cycle.Wefting insertion control part 44 is selected signal S1 based on weft yarn; The wefting insertion condition corresponding in a plurality of wefting insertion conditions of selecting to set with selecteed weft yarn; And, drive electromagnetic switch valve 34,36,37 etc. according to the wefting insertion condition of this selection, carry out the wefting insertion of selecteed weft yarn.In addition, in the present embodiment, weft yarn selects signal S1 to finish the next weave cycle in back at wefting insertion to begin (degree in crank angle is 0 °) preceding (for example: degree in crank angle is 340 °), selects signal generation 45 to export from weft yarn.
(3) select the weft yarn of signal generation 45 to select signal S1 from weft yarn, also outputed in the driving governor 62 of auxiliary jet control device 61a at each weave cycle.Driving governor 62 is read the setting value of the spray angle position of each the auxiliary jet group corresponding with selecteed weft yarn kind along with the input of weft yarn selection signal S1 from setting apparatus 63.
(4) then, driving governor 62 drives corresponding DD motor 51 simultaneously based on its setting value of reading, and makes the spray angle position (more particularly, the spray angle position of the auxiliary jet 22 that comprised of each auxiliary jet group) of each auxiliary jet group become said setting value.Specifically; Driving governor 62 calculates the differential seat angle of setting value with the setting value of the spray angle position of reading of present spray angle position; Stator 51a to DD motor 51 supplies with exciting current; So that the rotor 51b of DD motor 51 rotates the anglec of rotation of this angle residual quantity, make the rotor 51b of DD motor 51 and then auxiliary jet 22 is rotated, with the spray angle location change of auxiliary jet 22 setting value of the spray angle position of reading.
(5) after the rotation of the rotor 51b through DD motor 51 drove and makes the spray angle location change of auxiliary jet 22, driving governor 62 was with the driving of exciting current as the level control DD motor 51 that keeps electric current, to keep spray angle position after changing.
In addition, be for example according to the change (driving DD motor 51) of the spray angle position of the auxiliary jet 22 that is undertaken by driving governor 62 of above-mentioned (4): weft yarn selects signal S1 to take place to finish before wefting insertion time started of the next weave cycle in back.But,, therefore, to the weft yarn preference pattern of the continuous wefting insertion of weft yarn of identical type the time, have the setting value situation identical of the spray angle position of being read with last wefting insertion because weft yarn selects signal S1 to be exported at each weave cycle.Under this situation, driving governor 62 judges that said differential seat angle is zero, and the driving of control DD motor 51, so that the anglec of rotation of rotor 51b (the spray angle position of auxiliary jet 22) remains on present position.
More than in the regulator of the spray angle position of the auxiliary jet of the present invention 22 of one of explanation example; In the foregoing description; Corresponding to the weft yarn kind of wefting insertion change spray angle position; But be not limited in this, also can corresponding other weaving conditions (number of revolutions of fabric tissue, loom etc.) change spray angle position.
As the variation of the foregoing description, in weaving, carry out simultaneously the conversion of a plurality of weaving conditions the air injection type loom (for example: pile fabric loom), also can be in the weave patterns change spray angle position of each convertible a plurality of weaving condition.Under this situation, the spray angle position that is set in each weave patterns in the database is considered described a plurality of weaving condition and is set.
In the foregoing description; Select the input of signal S1 along with weft yarn; Driving governor 62 begins to be used to adjust the spray angle control of position; The change of spray angle position is that the wefting insertion at next weave cycle begins preceding end, but also instead is in this, with predefined degree in crank angle change spray angle position.Under this situation; This degree in crank angle (setting value) is set in the setting apparatus 63; And the degree in crank angle signal from encoder 42 is also outputed to (with reference to the dotted arrow of Fig. 1) in the driving governor 62; Arrive the time that is set in the setting value in the setting apparatus at degree in crank angle, driving governor 62 begins to be used to adjust the spray angle control of position, and the spray angle position of adjustment auxiliary jet 22.
Under the situation that aforesaid driving governor 62 is controlled according to the degree in crank angle of setting; Replace as above-mentioned embodiment in change simultaneously become the spray angle position of all auxiliary jets 22 of adjustment object, injecting time change spray angle position that also can corresponding each auxiliary jet 22.That is, as the auxiliary jet 22 that makes a plurality of auxiliary jet groups with auxiliary jet group unit of above-mentioned embodiment become under the situation of adjustment object because the injection beginning of each auxiliary jet group is different period, therefore, also can be corresponding each injection beginning period, make adjustment different period.
And; Under the situation about in weaving, adjusting according to the setting value of spray angle position; Behind the spray angle position of the auxiliary jet of having adjusted object 22, detect; When adjusted spray angle position produces offset with respect to the spray angle position of setting, also can revise this offset.In addition; When offset " produce " be meant, because influences such as extraneous overslaugh cause control problem, are blocked by miscellaneous parts such as warp thread, or the reason of plant failure; Cause the spray angle position not to be adjusted to setting value, produce deviation between adjusted spray angle position and the setting value.
Fig. 3 has represented to revise the auxiliary jet control device 61b of regulator of spray angle position of the auxiliary jet 22 of above-mentioned offset, as the variation of the auxiliary jet control device 61a of the embodiment of Fig. 1.Comprise not shown sensor (viewpoint position detection sensor) in this regulator, said sensor is arranged on each driver 51 or each auxiliary jet 22, detects the spray angle position of auxiliary jet 22.The driving governor 62 of the auxiliary jet control device 61a of this auxiliary jet control device 61b in embodiment, the setting apparatus 63, also has the arbiter 64 that is connected with above-mentioned viewpoint position detection sensor with Fig. 1.
The arbiter 64 of this auxiliary jet control device 61b also can be connected with driving governor 62 communicatedly.In such auxiliary jet control device 61b, behind the spray angle position of adjustment auxiliary jet 22, this spray angle position is detected by viewpoint position detection sensor, and the spray angle position Detection value that this is detected is outputed in the arbiter 64.64 pairs of said detected values of arbiter and the setting value of from driving governor 62, reading compare, and, as its comparative result, when producing deviation between the two, will differentiate the result and output in the driving governor 62.
More particularly, the method that adopts following steps to constitute, the offset of the spray angle position of regulator correction auxiliary jet 22.
(1) driving governor 62 is after for adjustment spray angle position rotating drive DD motor 51; The setting value of each auxiliary jet group of the conduct that will from setting apparatus 63, read adjustment object (more particularly, the setting value of the spray angle position of the auxiliary jet 22 that comprised of each auxiliary jet group) outputs in the arbiter 64.
(2) viewpoint position detection sensor detects the spray angle position of auxiliary jet 22, and the stipulated time after the rotating drive of DD motor 51 finishes (for example: predefined degree in crank angle), the detection signal of representing its detected value is outputed in the arbiter 64.
(3) arbiter 64 compares said setting value and said detected value in each auxiliary jet group, and when producing deviation (skew), the deviation signal that will represent this departure (side-play amount of the anglec of rotation) is as differentiating the result to driving governor 62 outputs.When not producing skew,, the deviation signal of representing this departure=0 is outputed in the driving governor 62, or deviation signal is not outputed in the driving governor 62 as zero deflection amount (=0).
(4) when producing skew, driving governor 62 is based on this deviation signal, and the stator 51a supply exciting current to DD motor 51 drives DD motor 51, to eliminate departure.More particularly, make the rotor 51b of DD motor 51 rotate the anglec of rotation of the angle residual quantity make departure=0.
When not producing skew, driving governor 62 is based on the deviation signal of expression this departure=0, or based on the situation of zero deflection signal, the driving of control DD motor 51 makes the rotor 51b of DD motor 51 remain on present angle position.
In addition, in the variation of this Fig. 3, in the above-mentioned record; For each driver 51 or each auxiliary jet 22 viewpoint position detection sensor is set, to detect the spray angle position of each auxiliary jet 22, based on each testing result; Carry out the control about the offset of the spray angle position of revising corresponding auxiliary jet 22, but also instead is in this, 1 in a plurality of auxiliary jets 22 that 1 unit of adjustment is comprised as representing; Viewpoint position detection sensor is set; Only to detect the spray angle position of this auxiliary jet 22,, carry out control about the above-mentioned offset of revising all auxiliary jets 22 that 1 unit of adjustment comprised based on its testing result.
In the variation of Fig. 3, when each adjustment spray angle position, differentiate whether produce offset, but be not limited in this, also can when whenever repeatedly adjusting the spray angle position, differentiate whether produce offset.
In addition, in the above-mentioned illustrated example, along with the conversion of weaving condition, in each weaving condition change spray angle position, but also instead detects the state of flight of weft yarn in this, and based on its testing result change spray angle position.
That is, among the embodiment of Fig. 1, imagine conversion along with weaving condition, the situation that the state of flight of weft yarn changes, and along with the spray angle position is changed in the conversion of this weaving condition.But, even discharge and by the weft yarn of wefting insertion, owing to along with reasons such as the woven unlocking resistance of carrying out weft yarn changes, the variation that also possibly produce the state of flight of weft yarn from identical confession yarn body (supply yarn body A or supply yarn body B).Therefore, also can detect the state of flight of weft yarn, and based on its testing result adjustment spray angle position.In addition; About detecting the state of flight of weft yarn, if the state of flight of weft yarn changes, the time (degree in crank angle) when then the front end of weft yarn is through the assigned position in the wefting insertion path changes; Therefore; (for example: middle assigned position, or the anti-assigned position that supplies the yarn side) is provided with the front end that the detects weft yarn sensor through (arrival) on the wefting insertion path, and according to this detection state of flight detected and to get final product.
Below, based on Fig. 4 to describing based on the embodiment of the regulator of the spray angle position of the testing result adjustment auxiliary jet 22 of the state of flight of weft yarn as stated.But the regulator of this embodiment is except the auxiliary jet control device, and is basic identical with the embodiment of Fig. 1, therefore, only representes the auxiliary jet control device 61c of present embodiment among Fig. 4, below, be that the center describes with this auxiliary jet control device 61c.
As shown in Figure 4, auxiliary jet control device 61c is except the driving governor 62 of the auxiliary jet control device 61a of embodiment with Fig. 1, the setting apparatus 63, also have comparator 65.The comparator 65 of this auxiliary jet control device 61c can be connected with driving governor 62, setting apparatus 63 and not shown main control unit communicatedly.
Among this embodiment,, adopt the weft yarn bobbin feeler (with reference to Fig. 1) 31 in the longitude yarn row outside of the anti-confession yarn side that is arranged on the air injection type loom as the sensor (through detecting sensor) of the front end that detects said weft yarn through (arrival).This weft yarn bobbin feeler 31 (through detecting sensor) is connected with said main control unit, and detect by the front end of the weft yarn of wefting insertion and arrive this surveyed area, and along with this testing result outputs to the weft yarn detection signal in the said main control unit.Based on this weft yarn detection signal, said main control unit calculates the time of advent (time of advent (detected value) of actual weft yarn) of weft yarn, and the detected value that calculates is outputed in the comparator 65.
On the other hand, be set with the time of advent of target in the setting apparatus 63 of auxiliary jet control device 61c, i.e. a reference value, and be set with the angle adjustment amount of the auxiliary jet 22 corresponding with the departure of time of advent (detected value) of this a reference value and actual weft yarn.
Said a reference value is read in the input of the comparator 65 corresponding said detected values of auxiliary jet control device 61c from setting apparatus 63, and said detected value and said a reference value are compared.As its comparative result, when producing deviation between the two, comparator 65 will represent that the deviation signal of this departure outputs in the driving governor 62.
More particularly, the method that adopts following steps to constitute, the spray angle position of regulator change auxiliary jet 22.
(1) through detecting sensor (weft yarn bobbin feeler 31) detect by the front end of the weft yarn of wefting insertion through the time, with the expression this testing result detection signal output in the not shown main control unit.
(2) main control unit calculates the time of advent (detected value) of actual weft yarn based on this detection signal, and the detected value that calculates is outputed in the comparator 65.
(3) time of advent (a reference value) of target is read in the input of comparator 65 corresponding detected values from setting apparatus 63, and this a reference value of reading and said detected value are compared.
(4) as its comparative result, when said a reference value and said detected value generation deviation, comparator 65 will represent that the deviation signal of this departure outputs in the driving governor 62.When not producing deviation, for there not being (=0), comparator 65 will represent that the deviation signal of this departure=0 outputs in the driving governor 62, or this deviation signal not outputed in the driving governor 62 as departure.
(5) when producing deviation, driving governor 62 towards the rotor 51b of the direction rotating drive DD motor 51 of eliminating said deviation, and changes the spray angle position based on this deviation signal.Specifically; Driving governor 62 is read the angle adjustment amount corresponding with said departure from setting apparatus 63; And the stator 51a of DD motor 51 supplied with exciting current, and drive DD motor 51, so that the rotor 51b of DD motor 51 rotates the anglec of rotation of this angle adjustment amount of reading.
When deviation did not take place, driving governor 62 was based on the deviation signal of expression this departure=0, or based on the situation that does not have deviation signal, the driving of control DD motor 51 is so that the rotor 51b of DD motor 51 remains on present angle position.
More than the processing of (1)～(5) can when each wefting insertion, carry out, the progress of also carrying out once behind the wefting insertion is for several times carried out termly, also can carry out in the special period of setting.
More than in the method for adjustment of the present embodiment of explanation; In setting apparatus 63, departure as parameter, is set the angle adjustment amount corresponding with this departure; But the angle adjustment amount corresponding with these parameters set as parameter in the spray angle position of auxiliary jet 22 that also can departure and adjustment is preceding.For example: when said departure is γ, when the spray angle position of the auxiliary jet 22 before the adjustment was θ 1, the angle adjustment amount was α, even said departure is similarly γ, but the spray angle position of the auxiliary jet 22 before the adjustment is when being θ 2, and the angle adjustment amount is β.Like this, the setting of spray angle adjustment amount can be more careful.
Preestablish the angle adjustment amount corresponding with departure, and the corresponding departure driving DD motor 51 that calculates, but also instead is only adjusted the only angle adjustment amount of regulation based on bias direction in this.In addition, so-called here bias direction is meant, the magnitude relationship with respect to the detected value of a reference value, be+(just) ,-any one of (bearing).Under this situation, in setting apparatus 63, replace the described angle adjustment amount corresponding, be set with the only angle adjustment amount of regulation with departure.But the direction that the angle adjustment amount in the setting apparatus 63 of being set in also can corresponding deviation (+,-) is different values.
Specifically, in the control of said (5), when producing deviation; 62 pairs of driving governors should deviation signal input; From setting apparatus 63, read the angle adjustment amount,, and drive DD motor 51 the stator 51a supply exciting current of DD motor 51; So that the rotor 51b of DD motor 51 towards the direction of representing with deviation signal corresponding with bias direction, rotates the anglec of rotation of the angle adjustment amount of reading.Repeat said (1)～(4) and comprise the processing of this correspondence (5) of only considering bias direction, till eliminating deviation.
In the above-mentioned explanation; Arrive the state of flight of time detecting weft yarn of allocation position of the weft yarn bobbin feeler 31 of the anti-confession yarn side that is arranged on the wefting insertion path at the front end of weft yarn; But be not limited in this; The time that also can arrive assigned position in the middle of the wefting insertion path of weft width direction (below, be called " middle assigned position ") through the front end that detects weft yarn carries out.In the detection of this situation, replace the anti-weft yarn bobbin feeler 31 that supplies the yarn side, adopt the release sensor that is attached to length measuring weft storing device 13, the sensor special that is arranged at middle assigned position.
For example: adopting under the situation that discharges sensor, this release sensor is attached to the length measuring weft storing device of explaining among the embodiment of Fig. 1 13, and detects the release of each volume of weft yarn on the drum barrel 15 that is wound on length measuring weft storing device 13.More particularly, on the outer peripheral face of the drum barrel 15 of length measuring weft storing device 13 shown in Figure 1, be wound with the weft yarn of a wefting insertion Len req, the weft yarn card stopped by card shotpin 16.When wefting insertion began, card shotpin 16 was retreated and the card of removing weft yarn ends from the outer peripheral face of drum barrel 15, and carries out injection action through main burner 21, with this weft yarn is released from drum barrel 15, carries out wefting insertion.At this moment, discharge the number of times that the d/d weft yarn of sensor crosses the sensor field that discharges sensor, and with this signal to Weft insertion controller 43 outputs such as (wefting insertion control parts 44).With this, Weft insertion controller 43 holds that the weft yarn of specific length is released from the drum barrel 15, and based on this situation, through ending weft yarn by card shotpin 16 cards once more, to the weft yarn wefting insertion of specific length.
Adopt to discharge under the situation of sensor, for example: if when the weft yarn of a wefting insertion Len req is 4 volumes for drum barrel 15, the leading section that the time that the weft yarn of 2 volume amounts is released (detections) in the wefting insertion of reality is equivalent to weft yarn arrives middle assigned position.Therefore, based on from the signal that discharges sensor, for example: main control unit calculates based on this degree in crank angle should the time (detected value), and the detected value that this calculates outputed in the comparator 65 get final product.In this case, in setting apparatus 63, be set with a reference value of the d/d time of weft yarn of said 2 volume amounts, and 65 pairs of said a reference values of comparator and said detected value compare and get final product with degree in crank angle.
Under the situation that adopts sensor special; Mode with the leading section that can detect weft yarn is provided with sensor near the assigned position of centre, and in setting apparatus 63, is set with a reference value of the front end of weft yarn through the time of the position of this sensor with degree in crank angle.Based on the signal from this sensor, same as described above, the weft yarn time of advent (detected value) of the assigned position in the middle of for example main control unit calculates based on degree in crank angle, 65 pairs of these detected values of comparator and said a reference value compare and get final product.
The present invention is not limited in above-mentioned illustrated example, can also be following distortion.
For the air injection type loom of the present invention as prerequisite; Among the said embodiment; 1 electromagnetic switch valve 36 is connected with a plurality of (among the said embodiment being 4) auxiliary jet 22; 1 auxiliary jet group is made up of a plurality of auxiliary jets 22, but is not limited in this, also can only connect 1 auxiliary jet 22 at 1 electromagnetic switch valve 36.Under this situation, though formation group not in fact we can say that also 1 auxiliary jet 22 is equivalent to 1 auxiliary jet group.Under this situation, maximum numbers of the auxiliary jet 22 that 1 unit of adjustment is comprised are 1.That is, carry out the adjustment of the spray angle position of auxiliary jet 22 with 1 unit.In addition, under the situation that 1 auxiliary jet group is made up of a plurality of auxiliary jets, its number is not limited in 4 of said embodiment, also can be below 3, or more than 5.
Among the said embodiment,, be with the group of all auxiliary jet groups as said adjustment object about the auxiliary jet group that constitutes by the auxiliary jet that is connected with shared electromagnetic switch valve 36; Promptly; Become the group under the auxiliary jet 22 of adjustment object, adjust the spray angle position of all auxiliary jets 22 that each auxiliary jet group comprised, promptly; With auxiliary jet all on the loom 22 as the adjustment object; But be not limited in this, in regulator of the present invention, the auxiliary jet more than 1 that will be connected with at least 1 electromagnetic switch valve 36 gets final product as the adjustment object.
For example: setting with auxiliary jet group unit under the situation of 1 unit of adjustment; Lean on most the anti-auxiliary jet group that supplies the yarn side for had very big influence power by the level of stretch of the weft yarn of wefting insertion owing to be positioned at; Therefore; Also can lean on the anti-auxiliary jet group that supplies the yarn side most with only being positioned at; Or comprise this and lean on most the anti-a plurality of auxiliary jet groups that supply the auxiliary jet group of yarn side, and the auxiliary jet group lacked than all auxiliary jet groups of quantity (for example: counter 3 auxiliary jet groups that supply the yarn side) as the group of adjustment object, each that will become this unit of adjustment organized the auxiliary jet 22 that is comprised and is made as 1 unit of adjustment with auxiliary jet group unit.Also can be only lean on most auxiliary jet group 22 that a plurality of auxiliary jet groups of the auxiliary jet group that supplies the yarn side and auxiliary jet group that quantity is lacked than all auxiliary jet groups comprised as adjusting object with being positioned at by the auxiliary jet group that supplies the yarn side or only will comprising to be positioned at; And the auxiliary jet group 22 that also can be only the auxiliary jet group more than 1 of the centre that is positioned at the fabric width direction be comprised is as the adjustment object.
Among the said embodiment; In the auxiliary jet group is in the air injection type loom that is made up of a plurality of auxiliary jets 22; 1 unit of adjustment is made up of all auxiliary jet groups 22 that 1 auxiliary jet group is comprised; But be not limited in this, the auxiliary jet 22 that also can quantity be lacked than the sum of a plurality of auxiliary jets 22 that constitute 1 auxiliary jet group is as 1 unit of adjustment.
For example: be under 4 the situation at the auxiliary jet 22 that constitutes 1 auxiliary jet group, can be with a plurality of auxiliary jets 22 below 3 as 1 unit of adjustment, even the auxiliary jet group is to be made up of a plurality of auxiliary jets 22, also can be only with 1 auxiliary jet 22 as 1 unit of adjustment.
And; Among the said embodiment; Under with the situation of group of a plurality of auxiliary jet groups, make number be identical (4), but be not limited in this as the auxiliary jet 22 of formation 1 unit of adjustment in each auxiliary jet group of adjustment object as the adjustment object; For a part of auxiliary jet group, can make also that to constitute the number of auxiliary jet 22 of 1 unit of adjustment different with other auxiliary jet groups.
Among the said embodiment, in 1 auxiliary jet group, only there is 11 unit of adjustment, but is not limited in this, in the auxiliary jet group that constitutes by a plurality of auxiliary jets 22, also can have 1 unit of adjustment more than 2.
For example: in the auxiliary jet group that constitutes by 4 auxiliary jets 22, also can make 2 of supplying the yarn side supply 2 of yarn side respectively as the pattern of 1 unit of adjustment, have 21 units of adjustment with anti-.
Among the said embodiment, the formation of drive unit as the spray angle position of change auxiliary jet 22 has adopted to be arranged on each auxiliary jet 22, and the direct DD motor 51 of driving auxiliary nozzle 22.But the drive unit in the regulator of the present invention is not limited in this, also can adopt drive transmission mechanism and be attached at other drivers (drive motors or rotary electric magnet etc.) 74 of auxiliary jet 22 through drive transmission mechanism, indirectly driving auxiliary nozzle 22.As the drive transmission mechanism under this situation, swing pinion, worm gear, rack pinion, band, chain etc. are arranged, represented concrete example among Fig. 5 (a)～(c).
