In the prior art, as shown in Figure 7, the publication application 62-162031 of Japan describes a kind of process units of special yarn, and the rotary speed of front roller is set to be zero when forming undercoat grain and provisionally the rotary speed of front roller is reduced to the value close with the rotary speed of rear roller when producing and becoming mildewed by provisionally.In the process units of the publication application 62-152031 of Japan, front roller and rear roller are driven by different variable speed motor.In addition, rotation is delivered to front roller from the variable speed motor of correspondence by two gear drives and two electromagnetic clutchs.When these two electromagnetic clutchs are in deactivation status, or during not-connected status, the rotation produced by this variable speed motor is not passed to front roller.When two electromagnetic clutchs are all in state of activation, or during connection status, the rotation produced by variable speed motor is to be passed to front roller than the speed reduced when only having one to be activated in described electromagnetic clutch.The connection of described two electromagnetic clutchs is controlled selectively with not being connected, thus produces undercoat grain and the grain that becomes mildewed.When forming undercoat grain, the rotation of front roller is stopped provisionally.
The rotary speed using electromagnetic clutch and gear drive suddenly to increase and to reduce front roller result in the labyrinth of machine and adds the cost of machine.In addition, under normal spinning speed (15-30m/min), when only changing the speed of variable speed motor with during by slowing down to front roller and accelerating to form undercoat grain, just require that variable speed motor has very large ability.And the transmission device of drive system is also required to have the intensity increased.
Summary of the invention
A target of the present invention is to provide a kind of method that production comprises the special yarn of undercoat grain, and does not reduce productivity and do not need electric clutch, and this is used to the rotary speed increasing suddenly and reduce front roller, or the motor of large ability, forms undercoat grain.
One aspect of the present invention is a kind of method for producing special yarn with spinning frame, it comprises the card nailing neps formed by the part thicker than the part with reference thickness, wherein spinning frame comprises drawing-off part, and in drawing-off part, front roller and rear roller are rotated by different variable speed motor.The rotary speed that the method comprises the steps: to reduce provisionally front roller and rear roller is with the speed be reduced to by spinning speed lower than normal spinning speed but before card nailing neps is formed, do not change the thickness of yarn, and is lowered to the described state lower than the speed of normal spinning speed from wherein spinning speed and performs card nailing neps and formed.
Above method is from the different of prior art, forms card nailing neps when spinning to reference thickness part with spinning speed by the rotary speed increasing suddenly and reduce front roller.More specifically, in the method, the rotary speed of front roller and rear roller is all reduced provisionally, and spinning speed is reduced by from normal spinning speed, and does not change the thickness of yarn before card nailing neps is formed.Then, start to form card nailing neps.Wherein in the state of speed lower than normal spinning speed, the speed of at least one in front roller and rear roller is changed with by reducing draw ratio to form card nailing neps from draw ratio when spinning to reference thickness part.Such as, by provisionally spinning speed being reduced to 1/3rd of normal spinning speed before card nailing neps is formed, the rate of deceleration of roller required in card nailing neps forming process and rate of acceleration can be lowered to during normal spinning 1/9th.Therefore, when forming extremely short card nailing neps, the speed of front roller and rear roller can not used large energy force motor as variable speed motor by changing smoothly.Therefore, do not need electromagnetic clutch or when forming undercoat grain, front roller suddenly can be accelerated and slow down by force motor greatly.In addition, the special yarn comprising undercoat grain can be produced when not reducing productivity.

Front roller 17(illustrate only bottom roll) define drawing-off part 16, front roller 17 is coupled to the first servo motor 18, and it is used as variable speed motor.Middle roller 19(illustrate only bottom roll) be coupled to the second servo motor 20, it is used as variable speed motor.After rear bottom roll 21(, top roller is not shown) be connected to middle roller 19 by gear train 22.In this embodiment, middle roller 19 and rear bottom roll 21 form rear roller.Also namely, front roller 17 and middle roller 19, or rear roller each is all driven by different variable speed motor.These two servo motors 18 and 20 comprise rotary encoder 18a and 20a respectively.Middle roller 19 comprises apron 19a.Gear 17a is fixed to front roller 17 and along with front roller 17 integral-rotation.Sensor s1 is disposed in the vicinity of gear 17a with the rotation output pulse signal according to front roller 17.
Controller 23 controls motor 2,14,18 and 20, and controller 23 comprises CPU (CPU) 24, program internal memory 25, working memory 26 and input equipment 27.CPU24 is connected to inverter 6 and servo-driver 15 by output interface and motor drive circuit (not shown).In addition, CPU24 is connected to the first servo motor 18 by output interface (not shown), motor drive circuit (not shown) and servo-driver 28.CPU24 is also connected to the second servo motor 20 by output interface, motor drive circuit and servo-driver 29.
CPU24 is by the preset program data manipulation be stored in program internal memory 25.Program internal memory 25 is formed by read-only storage (ROM) and program data and the various data required for performing a programme data.
Routine data comprises program for controlling motor 2 and servo motor 14 in operating winding, for driving the control program of the first servo motor 18 and the second servo motor 20 and change the control program of the speed of the first servo motor 18 and the second servo motor 20 when forming card nailing neps in normal spinning process.Routine data comprises the data by spinning situation and velocity correlation.Spinning situation comprises the spinning yarn number, draw ratio etc. of fiber type, reference thickness.Speed is included in the rotary speed of the spindle during normal spinning, the first servo motor 18 and the rotary speed of the second servo motor 20 and the hoisting velocity of ring-shaped guide rail 8 and decrease speed.
Working memory 26 is readable and can writes internal memory, such as random-access memory (ram), and stores the result of calculation of data and the CPU24 inputted by input equipment 27 temporarily.Working memory 26 comprises back-up source (not shown).
Input equipment 27 is used to input spinning status data, the spinning yarn number of such as special yarn pattern data, reference thickness, spindle rotary speed when spinning to the yarn of reference thickness, promotes length, cop conical surface hypotenuse length etc.As shown in fig. ib, the pattern data of special yarn comprises card nailing neps length Ls, and it is the card nailing neps S(thick thread segment thicker than the reference thickness part Y0 of special yarn SY) length; And the pitch length P of card nailing neps S, it is the length of the reference thickness part Y0 between card nailing neps S.Pattern data instruction timing changing speed is formed to realize card nailing neps, and namely when starting to underspeed before card nailing neps is formed and when starting card nailing neps is formed.In addition, pattern data is by Length Indication of spinning.Spinning length is calculated based on the output signal carrying out sensor s1.
The rotary speed single step of each in roller 17,19 and 21 is not changed to from the speed being used for normal spinning the speed formed for card nailing neps by the control program of the first servo motor 18 and the second servo motor 20.Or rather, before changing to card nailing neps formation speed, rotary speed is changed to predetermined speed by control program, and this predetermined speed, lower than normal spinning speed, keeps draw ratio constant simultaneously.Then, rotary speed is changed to card nailing neps and forms speed by control program.Specifically, as shown in fig. ia, in roller 17,19 and 21, the rotary speed of each is reduced to lower predetermined speed by from normal spinning speed.Then front roller 17 is maintained at this lower speed, and middle roller 19 and rear bottom roll 21 each be accelerated to card nailing neps formed speed and remain on this card nailing neps formed speed reach predetermined time length.Also namely, card nailing neps starts at the end of being formed in the rotary speed reduction of front roller 17, middle roller 19 and rear bottom roll 21 immediately.Afterwards, middle roller 19 and rear bottom roll 21 each are decelerated to the comparatively low velocity identical with the speed set before card nailing neps formation speed.In other words, the rotary speed of middle roller 19 and rear bottom roll 21 is set to the speed of last setting before card nailing neps is formed.After this, while maintenance draw ratio is constant, each in roller 17,19 and 21 is accelerated to rotary speed of normally spinning, and after this normally spins.
Now by the operation of tracing device.Before operating means, input equipment 27 is utilized to input spinning situation.The spinning situation of input comprises data, the spinning yarn number of such as special yarn pattern data, reference thickness, spindle rotary speed when spinning to the yarn of reference thickness, promotes length, cop conical surface hypotenuse length etc.
When device is activated, controller 23 sends the order of CD-ROM drive motor 2, servo motor 14, first servo motor 18 and the second servo motor 20.CPU24 uses the output signal of rotary encoder 2a, 14a, 18a and 20a to calculate the rotary speed of corresponding motor.CPU24 sends command signal by output interface and each drive circuit to inverter 6 and servo-driver 15,28 and 29 and synchronously drives spindle drive system, drawing-off portion drive system with the predetermined speed corresponding with spinning situation and promote drive system.Spindle drive system, drawing-off portion drive system and lifting drive system are synchronously driven with state independent of each other.The special yarn SY be fed to from drawing-off part 16 is reeled by round peg or spindle B by volute thread-carrier 9 and steel traveler T.
When spinning to reference thickness yarn, CPU24 uses the output signal of sensor s1 to calculate the rotary speed of front roller 17, also, and spinning yarn length.When spinning to card nailing neps S, each in front roller 17, middle roller 19 and rear bottom roll 21 is decelerated to predetermined comparatively low velocity from the rotary speed being used for normal spinning by CPU24, but does not change yarn thickness, also, keeps draw ratio constant simultaneously.Then, in order to card nailing neps is formed, front roller 17 is maintained at predetermined comparatively low velocity.Middle roller 19 and rear bottom roll 21 each are accelerated to card nailing neps formation maximal rate and maintain this card nailing neps generation maximal rate and reach the scheduled time.Then, middle roller 19 and rear bottom roll 21 are decelerated to predetermined lower rotary speed.After this, roller 17,19 and 21 each is accelerated to normal spinning rotary speed and keeps draw ratio constant simultaneously.Then, execution is normally spinned.Then, special yarn spinning is performed in an identical manner.
As a result, as shown in Figure 1A, when the predetermined speed lower than normal spinning speed increases, become thicker than reference thickness the rotary speed of special yarn SY from middle roller 19 and rear bottom roll 21 each.The rotary speed of special yarn SY each in middle roller 19 and rear bottom roll 21 reaches when card nailing neps forms maximal rate and becomes the thickest.The part with maximum gauge is maintained in time period that card nailing neps produces maximal rate in the rotary speed of middle roller 19 and rear bottom roll 21 to be formed.Then, the rotary speed in middle roller 19 and rear bottom roll 21 each be lowered to card nailing neps formed setting when starting compared with defining in the time period of low velocity from maximum gauge part thinning gradually.Card nailing neps length Ls refers to the length of the part with the thickness different from reference thickness.
When decelerating to predetermined comparatively low velocity from normal spinning rotary speed from roller 17,19 and 21 each the absolute value of the deceleration gradient of (from time t1 to time t2 Figure 1A) be set to from roller 17,19 and 21 each card nailing neps is formed terminate after accelerate to normal spin rotary speed time (from time t3 to time t4 in Figure 1A) the absolute value of accelerating gradient identical.In order to form undercoat grain and not obvious reduction productivity, the time for slowing down is needed as 0.3 second or less, and the deceleration gradient between card nailing neps Formation period is set to the value that corresponds to normal spinning speed and slow down the target velocity after terminating.And the accelerating gradient of rear roller (middle roller 19 and rear bottom roll 21) and deceleration gradient are set to have identical absolute value between card nailing neps Formation period.Card nailing neps formation time length (from time t2 to time t3) is set to 0.4 second or less, and the accelerating gradient between card nailing neps Formation period is set to be formed with card nailing neps rotary speed when starting and card nailing neps forms value corresponding to maximal rate.By this way, preparatory stage before being formed from card nailing neps (decelerate to card nailing neps from normal spinning speed and form commencing speed) to card nailing neps formed and speed turns back to original spun speed time time be one second or less.
CPU24 card nailing neps formed timing close to time use spinning yarn length to come to calculate according to spinning situation the time point (the time t1 in Fig. 1) reducing spinning speed.It is identical with the pitch P in pattern data by the pitch length P of the card nailing neps S calculating to make in special yarn SY that card nailing neps forms starting point, and spinning speed has been slowed down a little define card nailing neps formation starting point.
In the prior art, when spinning to reference thickness part, the spinning speed of front roller 17 is slowed down suddenly or is accelerated to form card nailing neps.The present embodiment difference with the prior art is, card nailing neps form front draft than do not change and the rotary speed that card nailing neps forms each from front roller 17 and rear roller (middle roller 19 and rear bottom roll 21) is reduced to reduce spinning speed time.By this way, in front roller 17 and rear roller, the rotary speed of at least one is changed by from the state lower than normal spinning speed (such as, 15-30m/min), and after this, draw ratio is reduced by from the draw ratio of spinning to reference thickness part Y0.
The rate of acceleration of the rotary speed of the roller required when formation has the card nailing neps of full-length (the card nailing neps length of 30mm or larger) and spinning speed square proportional.In addition, compared with during formation standard card nailing neps, the roller rate of acceleration when forming undercoat grain (being less than the card nailing neps length of 30mm) is needed as obviously larger (about 3-10 doubly).But, such as, by spinning speed being reduced to 1/3rd of normal spinning speed provisionally before card nailing neps is formed, roller rate of acceleration required between card nailing neps Formation period and rate of acceleration can be reduced to required by normal spinning 1/9th.Therefore, when forming extremely short card nailing neps, the speed of front roller 17 and rear roller can be changed smoothly, and does not use the motor with large ability as variable speed motor.
The present embodiment has advantage as described below.
(1) special yarn SY comprises the part being called as card nailing neps, card nailing neps is thicker than the part with reference thickness, this special yarn SY utilizes spinning frame to produce, this spinning frame comprises drawing-off part 16, in this drawing-off part 16, front roller 17 and rear roller (middle roller 19 and rear bottom roll 21) are driven by different variable speed motor.In addition, before card nailing neps is formed, do not change yarn thickness, the rotary speed of front roller 17 and rear roller (middle roller 19 and rear bottom roll 21) is reduced provisionally.After spinning speed is reduced from normal spinning speed, start card nailing neps and formed.Therefore, the motor that the formation of undercoat grain does not require electromagnetic clutch or has a large ability reduces suddenly or increases the rotary speed of front roller 17, and the special yarn comprising undercoat grain can be produced when not obvious reduction productivity.
(2) between card nailing neps Formation period, the rotary speed of rear roller (middle roller 19 and rear bottom roll 21) is increased to reduce draw ratio.By this way, between card nailing neps Formation period, rear roller is accelerated and does not change the speed of front roller 17.Therefore, compared with when only accelerating front roller 17, reduce the driving load on front roller 17, and improve productivity.
(3) arrange accordingly with spinning situation card nailing neps formed before front roller 17 and the deceleration gradient of rotary speed of rear roller.Deceleration gradient can be fixing and no matter spinning situation is how.But, preferably, the time for slowing down is short.By arranging deceleration gradient accordingly with spinning situation, the deceleration gradient shortening deceleration required time can be set, make do not have excessive power to be applied in drawing-off part 16.
Those skilled in the art should understand, when not departing from the spirit or scope of the present invention, the present invention can be implemented by other concrete forms many.Especially, should be understood that, the present invention can implement by form the following.
As shown in Figure 3, between card nailing neps Formation period, the rotary speed of front roller 17 can be lowered to reduce draw ratio.In this case, between card nailing neps Formation period, draw ratio can be reduced by means of only the rotary speed reducing front roller 17.
Therefore, without the need to performing the control to the speed changing rear roller.Therefore, for driving the rotary speed of the second servo motor 20 of rear roller higher than the rotary speed for normally spinning, and need not can use the motor with low maximal rate.
As shown in Figure 4, between card nailing neps Formation period, except accelerating rear roller, also can slow down to front roller 17.In this case, the variable quantity of front roller 17 and the speed of rear roller can be reduced with compared with when changing the speed of front roller 17 or draw ratio be reduced to desired value by means of only the speed changing rear roller.
According to spinning frame illustrate or will by the spinning situation of the special yarn produced can adopt in three kinds of programs below any one.
(1) in order to card nailing neps is formed, increase and reduce the rotary speed of front roller 17.
(2) in order to card nailing neps is formed, increase and reduce the rotary speed of rear roller.
(3) in order to card nailing neps is formed, the rotary speed increasing and reduce front roller 17 also increases simultaneously and reduces the rotary speed of rear roller.
Perform in the rotary speed by increasing and reduce front roller 17 in the program of card nailing neps formation, the load being applied to front roller 17 increases.Therefore, preferably this program is used when front roller drive system has enough power.Perform in the rotary speed by increasing and reduce rear roller in the program of card nailing neps formation, the load being applied to front roller 17 increases.Therefore, preferably this program is used when rear roller drive system has enough power.The rotary speed also increasing simultaneously and reduce rear roller in the rotary speed by increasing and reduce front roller 17 performs in the program that card nailing neps formed, and the load being applied to front roller 17 and rear roller is between the load applied in above two programs.Therefore, preferably this program is used when front roller drive system and rear roller drive system do not have enough power.
Between card nailing neps Formation period, front roller 17 is decelerated or rear roller is accelerated draw ratio to be reduced from the draw ratio of spinning to the part with reference thickness.When front roller 17 and rear roller reach their target velocity, target velocity need not be maintained.As shown in Figures 5 and 6, front roller 17 and rear roller can be controlled to make to slow down and accelerate to be started immediately.
When reducing the rotary speed of front roller 17 between card nailing neps Formation period, speed can be lowered to zero.Also namely, front roller 17 can be stopped provisionally.
Replace driving middle roller 19 and rear bottom roll 21 with the second identical servo motor 2, middle roller 19 and rear bottom roll 21 can be driven by different variable speed motor.
Can arrange deceleration gradient absolute value when decelerating to predetermined low speed from normal spinning rotary speed in roller 17,19 and 21 each to be different from the absolute value of accelerating gradient when accelerating each roller 17,19 and 21 after card nailing neps has been formed.
Deceleration gradient when decelerating to predetermined low speed to each in roller 17,19 and 21 from normal spinning rotary speed and accelerating gradient when accelerating each roller 17,19 and 21 after card nailing neps has been formed can be stored in program internal memory 25 or working memory 26 accordingly in advance with spinning situation.
Card nailing neps is formed and need not start at the end of the deceleration of front roller or rear roller, and slightly can postpone at the end of this deceleration.But, the spinning state being preferably different from normal spinning is short.Therefore, at the end of deceleration, preferably start card nailing neps immediately to be formed.
Replace no matter when inputting spinning situation all will input card nailing neps and form spinning speed when starting, can be stored in accordingly program internal memory 25 with the thickness of card nailing neps S and length in advance from the rate of deceleration of normal spinning speed.In this case, CPU24 can automatically arrange according to spinning situation the spinning speed started when card nailing neps is formed.
This example and embodiment are considered to illustrative and nonrestrictive, and the present invention is not restricted to the details provided herein, but are changed in the scope and equivalent way of claims.
