Description
Technical field
The present invention relates to and avoid the method for lap wound (patternwinding) at the winding intersected coiled bobbin period of the day from 11 p.m. to 1 a.m and perform the device of such method.
Cross winding bobbin is manufactured by corresponding weaving loom, and this weaving loom is generally made up of many identical stations manufacturing cross winding bobbin respectively, and these stations are by the central means of weaving loom, and such as electric supply installation is powered.Such weaving loom especially can be automatic winder, the cross winding bobbin of its thread material that to have become to have had many by the multiple cop rewinding relative to little package many, or this weaving loom also can be spinning machine.
Background technology
In cross winding bobbin, yarn relative to cross winding bobbin longitudinal axis floor-covering roll around.Now, yarn first such as shifts to its right-hand member side with degree of dip to the right from cross winding bobbin left end side, shift to left end side to change over to be tilted to the left and to return therefrom in arrival right-hand member rear flank subsequently, terminate so-called reversion stroke whereby and converted by inclination and appear at the intersecting angle of the yarn on cross winding bobbin.
Except the utilization transverse shifting thread-carrier that back switching moves from left to right and again, in order to obtain traverse motion, and the serrated roller with reversion thread groove (reversingscrewthreadgrooves) is used to guide yarn to be a kind of cheapness and thus conventional possible mode.Generally, such serrated roller is used to drive this cross winding bobbin simultaneously.For this reason, the serrated roller being also referred to as head roll is subsequently in the frictional engagement with cross winding bobbin, and described head roll is identical with the circumferential velocity of cross winding bobbin, except the situation of different caused by slippage.
Because the rotation of head roll and cross winding bobbin is the periodic process that is mutually related in the case, therefore in certain cross winding bobbin diameter situation, there is the formation of so-called decorative pattern overlap or decorative pattern, namely, after doublestroke (doublelift) terminates completely, yarn is fallen to putting to have fallen to being placed in doublestroke comparatively early at it this same position or its immediate again.
This situation such as always appears at and one or more complete cross winding bobbin has occurred at the end of doublestroke completely when turn-taking.
That is, yarn therefore directly or overlapping or be closely in such position up and down separatedly by yarn interlayer, and create a) higher rolling density and b) unstable thread layers thus in this position.The former is disadvantageous when cone dyeing, because such thickening position is less preferably soaked into compared with all the other positions, is therefore only dyeed unevenly.The latter reels unfavorable in stability and the backing-off performance when cross winding bobbin unwinding subsequently, because the thread layers slippage of stacked on top of one another and may blocking each other.
The problem forming decorative pattern overlap is known for a long time, and develops many methods anti-stacked for what is called, namely avoids above-mentioned harmful periodicity to associate, way be people change described head roll with the relative circumferential velocity of cross winding bobbin.For this reason, people such as can alternately accelerate, slow down (decelerate) or the head roll itself that dallies, can this cross winding bobbin of temporary deceleration, or can by limited for the cross winding bobbin head roll that is lifted away from be changed friction between head roll and cross winding bobbin, and people also can combine all these may modes.Simultaneously challenge now obtains sufficient anti-stacked effect in minimum additional energy consumption with maintenance is high-production.
EP0399243B1 mono-aspect gives the general view to known method, propose the method for oneself on the other hand, at this, so alternately periodically accelerate and this head roll that slows down, the circumferential velocity of cross winding bobbin is such as followed after the circumferential velocity of head roll with fixing phase displacement.Thus, the difference of the circumferential velocity of head roll and the circumferential velocity of cross winding bobbin is all the time in change, and this causes actv. anti-stacked.
Summary of the invention
Therefore, in view of this background, task of the present invention so improves known anti-stacked method and the said method of especially EP0399243B1, that is, multiple target component, at least one parameter namely in anti-stacked quality, capacity rating and energy consumption is improved.
This task avoids the method for lap wound by a kind of at the winding intersected coiled bobbin period of the day from 11 p.m. to 1 a.m, cross winding bobbin is driven by the head roll being equipped with the reversion thread groove guided for yarn, wherein this head roll has multiple acceleration phase, followed by a decelerating phase after each acceleration phase, it is characterized in that, this head roll is at acceleration phase and have the circumferential velocity higher than cross winding bobbin in the decelerating phase, moment residing when the circumferential velocity that this decelerating phase ends at this head roll is reduced to the circumferential velocity of cross winding bobbin, and follow a synchronous phase respectively after this decelerating phase, described in this synchronous phase, the circumferential velocity of head roll is equal with the circumferential velocity of described cross winding bobbin.
But this task also avoids the device of lap wound by a kind of at the winding intersected coiled bobbin period of the day from 11 p.m. to 1 a.m, comprising: the head roll for driving cross winding bobbin being equipped with the reversion thread groove guided for yarn; One or more for providing signal to determine the sensor of the circumferential velocity of head roll and cross winding bobbin; The circumferential velocity for head roll described in the calculated signals by described one or more sensor and cross winding bobbin be connected with described one or more sensor and control the control unit of the circumferential velocity of head roll, wherein this control unit arranges and is used for operating this head roll immediately following having in multiple acceleration phases in a decelerating phase respectively, it is characterized in that, this control unit arranges and is used for: operate this head roll at acceleration phase with in the decelerating phase with the circumferential velocity higher than cross winding bobbin; When the circumferential velocity of head roll is lowered to the circumferential velocity of cross winding bobbin, the residing moment terminates this decelerating phase; After a decelerating phase, operate this head roll in synchronous phase respectively, in this synchronous phase, the circumferential velocity of described head roll is equal with the circumferential velocity of described cross winding bobbin.
The present inventor now recognizes, compared to EP0399243B1, when people so shorten the decelerating phase driving and roll, namely, when people are reduced to the circumferential velocity of cross winding bobbin from the circumferential velocity of head roll, the residing moment reinstates and replaces the decelerating phase without the idle running driven, that is, reinstate synchronous phase from this moment and substitute the decelerating phase, the anti-stacked effect that people also can obtain fully or even improve.Be different from the viewpoint avoiding synchronous phase completely supported in EP0399243B1, the present inventor recognizes that the limited synchronous phase of duration is completely acceptable.
But, by arranging synchronous phase according to the present invention, compared to EP0399243B1, the circumferential velocity avoiding head roll is reduced to the circumferential velocity being less than cross winding bobbin, energy consumption needed for this cross winding bobbin saved on the one hand for this reason for occurring subsequently slows down, also avoids the energy consumption for needing again cross winding bobbin to accelerate to its circumferential velocity before braking subsequently in acceleration phase on the other hand.The energy consumption of the method that therefore energy consumption of the inventive method proposes lower than EP0399243B1.In addition, be not reduced to the circumferential velocity being less than cross winding bobbin by head roll circumferential velocity, avoid yarn must be pulled through under the large friction between intersected coiled bobbin and head roll as far as possible, it is dangerous that this reduces yarn breakage.
People preferably can by according to of the present invention by before and after multiple order that acceleration phase, decelerating phase and synchronous phase are formed closely in succession, namely whole operating process was made up of these stages.But this is not necessarily because or these stages also can only the such as place in operation when the cross winding bobbin diameter overlapping crucial for decorative pattern by accident, and this head roll such as can operate with constant circumferential velocity in other cases.This also can obtain still acceptable anti-stacked effect in some cases., the parameter in described stage can also become according to the actual diameter of cross winding bobbin just as in EP0399243B1 correspondingly, namely such as selects the time length in some stages and its acceleration force or deceleration force relatively with diameter.
Advantageously, so can determine the time length of acceleration phase and synchronous phase, that is, this acceleration phase residing moment when head roll circumferential velocity reaches speed limit is moved to end, and this synchronous phase residing moment when head roll circumferential velocity reaches lower velocity limit is moved to end.This has following advantage, can reliably avoid head roll circumferential velocity and and then the too great fluctuation process of cross winding bobbin circumferential velocity.
When the method is exclusively used in that head roll is accelerated by constant acceleration torque in acceleration phase, head roll is decelerated by constant deceleration torque in the decelerating phase and this head roll is not subjected to torque in synchronous phase, obtain the simple especially situation in decelerating phase and decelerating phase.
Finally, so obtain operator and can use the method especially simply, namely so determine acceleration torque, when obtaining by the predetermined deboost phase ratio (v of method user by when the ratio of the predetermined acceleration torque of method user with deceleration torque

In order to perform the method, especially can be that apparatus of the present invention of the winding position of bobbin-winding machine or spinning machine (in the case especially rotor spinner) only need usually known constituent elements at hardware aspect, and method illustrate and can be stored in a software form in this device control units.In weaving loom situation, this control unit now can be arranged separately on its each station or to be arranged on weaving loom in central authorities and also can to fulfil other control task unrelated to the invention.
These known and angular velocity sensoies such as also described in EP0399243B1 and the also known and cross winding bobbin diameter described in EP0399243B1 are determined (according to the average specific of the cireular frequency of cross winding bobbin and head roll, to be optically by light source and photoemissive element mechanism, position, bobbin bank angle) relatively for determining the circumferential velocity of described head roll and cross winding bobbin.But because precision is higher, therefore directly measure yarn speed to determine cross winding bobbin circumferential velocity preferably by sensor, this sensor is passed through by yarn and such as associates principle or LDA principle based on decorative pattern.For this reason, the relation that yarn speed is familiar with according to technical personnel is subsequently scaled winding speed.All embodiments described above and combination thereof all belong to the present invention.

Detailed description of the invention
Obtain from EP0399243B1 basic and there as in Fig. 1 and Fig. 2 shown in Fig. 2 and Fig. 5, simplify with schematic front view and lateral plan the winding position 1 set up according to the present invention showing bobbin-winding machine.
On winding position 1, drive by friction the cross winding bobbin 8 be bearing in bobbin maintaining part 9 by head roll 2.Now, the yarn 7 extracted out from cop 28 is winding to cross winding bobbin 8.Yarn 7 utilizes the reversion thread groove 2 of head roll 2 " axis that is parallel to cross winding bobbin 8 lays.Now there is desired cross winding.
Head roll 2 is arranged in the frame 3 of bobbin-winding machine via drum shaft 2 '.Drum shaft 2 ' be driven through with vee-belt 4 " belt pulley 4 and 4 ' that is connected realizes, wherein this belt pulley 4 ' is driven by electrical motor 6 '.But, replace utilizing leather belt driving mechanism 4,4 ', 4 " also can and universal be by electrical motor 6 ' Direct driver drum shaft 2 '.The electrical motor 6 ' that can control with 4 quadrant operation scheme is controlled by inverted rectifier 16, and inverted rectifier obtains its control command by control path 15 ' by the control unit 14 of winding position self.
Control unit 14 from sensor 12,10 and 31 obtain about head roll 2 with the information of the circumferential velocity of cross winding bobbin 8.For this reason, what the sensor 12 and 10 such as responsively formed in the pulse generator of rotational angle measured head roll 2 is transferred to control unit 14 by circuit 11 and 13 with the cireular frequency of cross winding bobbin 8, and control unit can calculate its circumferential velocity by the diameter of known head roll 2 subsequently at once.The position, angle of sensor 31 measuring cylinder subrack 29, bobbin bank is equipped with bobbin maintaining part 9 and itself is arranged in bobbin bank axle 30.Its signal is sent to control unit 14 by circuit 32 by the sensor 31 that such as can be formed to rotate resistance form, and control unit is calculated the diameter of cross winding bobbin 8 by the position, angle of bobbin bank 29 and utilized the turn meter transmitted by sensor 10 to calculate the circumferential velocity of cross winding bobbin 8 subsequently.
But as an alternative and because precision is higher preferably, cross winding bobbin 8 circumferential velocity can as already described by with sensor (yarn process and such as based on decorative pattern association principle or LDA principle) directly measure yarn speed and determine.For this reason, yarn speed subsequently by technical personnel the relational expression be familiar be converted into the circumferential velocity of cross winding bobbin 8.
But when people want the simple machine of limiting sensor cost also it is possible that abandon yarn speed and measure and also abandon the angle displacement measurement of bobbin bank 29.For this reason, people temporarily disconnect the driving of head roll 2, and this was the component part of many conventional anti-stacked methods originally.As long as this disconnection is long enough, cross winding bobbin 8, because it is finally in the circumferential velocity the same with head roll 2 with the frictional fit of head roll 2, namely transits in the operation moved without slippage.
Therefore, in this operation without slippage, cross winding bobbin 8 moment diameter can from head roll 2 with the cireular frequency of cross winding bobbin 8 and and known head roll 2 diameter determine.In this simplest modification, it is constant that this diameter can be considered as before the upper diameter without the next time in slip phase is once determined by people, and can go out have from its angular speed calculation the circumferential velocity of the cross winding bobbin 8 of this diameter.But in more detailed modification, when people also utilize other known parameter for this reason, during horizontal return motion speed as yarn diameter and such as cross winding, this diameter is increased and also can be calculated by cross winding bobbin 8 known angle speed in time.
Also illustrate that yarn monitor 26 upwards walked by the yarn being arranged on yarn 7 further, this yarn monitor is also connected with control unit 14 by circuit 27.If yarn monitor 26 demonstrates the fault of yarn 7, i.e. broken yarn, then control unit 14 passes through control path 15 ' with inverted rectifier 16 by electrical motor 6' power-off.
Method of the present invention such as can realize by changing the software run in control unit 14 when not utilizing known constituent elements as depicted in figs. 1 and 2 with changing.Therefore, described software is used for the sequential according to acceleration phase of the present invention, decelerating phase and synchronous phase, and this sequential is also referred to as anti-stacked cycle BZ and is shown schematically with the change view of the circumferential velocity v relative to time t in figure 3.
At this, acceleration phase BP beginning from basic synchronization state, i.e. beginning from following state, now the circumferential velocity v of head roll 2
trwith the circumferential velocity v also having cross winding bobbin 8
krsubstantially lower velocity limit v is equaled
u.Subsequently, electrical motor 6 ' applies constant positive current as 1.76A by inverted rectifier 16, until acceleration phase BP terminates, this end is then the circumferential velocity v at head roll 2
trreach speed limit v
oin time, reaches.Because its inertia and cross winding bobbin 8 are relative to the limited frictional engagement of head roll 2, in acceleration phase BP, cross winding bobbin 8 can only postpone to follow after head roll 2, that is, the circumferential velocity v of cross winding bobbin 8
kralways lower than the circumferential velocity v of head roll 2
tr.That is, between these two speed, slippage S is formed.
Once the circumferential velocity v of head roll 2
trreach speed limit v
o, then acceleration phase BP proceeds to decelerating phase AP.Now, apply constant negative current, such as applying-0.64A to electrical motor 6 ' by inverted rectifier 16, until decelerating phase AP terminates, this decelerating phase terminates, and is the circumferential velocity v at head roll 2
trwith the circumferential velocity v of cross winding bobbin 8
krbe in figure 3 with v

trsuccessively decrease by slowing down.Once these two circumferential velocity v

bg, control unit 14 just terminates decelerating phase AP and so starts synchronous phase GP, and namely it is by electrical motor 6 power-off.
In synchronous phase GP below, head roll 2 and cross winding bobbin 8 slow down because of its inertia slowly, and here, the frictional engagement between them is used for making its circumferential velocity v

Subsequently, therefore preferably will begin in a minute the next anti-stacked cycle BZ be made up of acceleration phase BP, decelerating phase AP and synchronous phase GP, that is, anti-stacked cycle BZ preferably directly regularly repeats successive.But as an alternative, people also can insert the circumferential velocity v with constant head roll 2 between anti-stacked cycle BZ

For bobbin-winding machine operator and advise, by setting average velociity v
mand velocity lag Δ v=v

ucontrol the method, because average velociity v
monly be slightly higher than the average winding speed obtained when reeling cross winding bobbin 8, i.e. the leveled circular circular velocity v of head roll 2
kr, its as productivity parameters for operator's important in inhibiting.And velocity lag Δ v can very intuitively as average velociity v
mpercentum provide, here, this percentum should not select get Tai Gao, this is because speed limit v

m=1200m/min; Δ v=9%v
m=108m/min, therefore v
u=1146m/min and v
o=1254m/min.
If as in a preferred embodiment, in the ratio of this acceleration torque and deceleration torque embodiment in fig. 1 and 2, namely accelerate electric current and keep constant with the ratio of deceleration electric current, then the length in decelerating phase can by operator by setting the deboost phase than BPV=(v
o-v
bg)/(v

u) provide.The representative value of BPV is 15% and 10%.
Deboost phase when cross winding bobbin reels on the impact of energy consumption than BPV will be checked according to test and such as be illustrated in figs. 4 a and 4b, here, the energy consumption (Ws/km) of unit winding yarn length is shown about cross winding bobbin diameter (mm).At winding stroke section start, namely when cross winding bobbin diameter hour, this energy consumption is very high, but shows greatly hyperbolic form rapid decrement immediately to saturation value.The non-eigenwert of the some measurement points changed by normal profile infers broken yarn and meaningless for basic energy consumption.
Article two, experiment curv except the deboost phase than except BPV based on the same terms: v
m=1200m/min; Δ v=9%v
m=108m/min, therefore v
u=1146m/min and v
o=1254m/min.At this, have employed the head roll of modern light-duty Ball support.For the experiment curv of Fig. 4 a, according to the head roll circumferential velocity v at the end of the decelerating phase
tr=v
bg=v
o-BPV Δ v=(1254-15%108) m/min=1237.80m/min, adopts the deboost phase of BPV=15% than BPV immediately, and for the experiment curv in Fig. 4 b, according to v
bg=(1254-10%108) m/min=1243.20m/min, adopts the BPV of BPV=10%.
As already described, less deboost phase ratio causes the decelerating phase to shorten.This clearly shows that lower acceleration torque used immediately in acceleration phase causes the less slippage between head roll and cross winding bobbin thus, and therefore the circumferential velocity at the end of its acceleration phase has only differed smaller value.That is, need only slow down less velocity contrast in the decelerating phase subsequently, and this result in the shortening in decelerating phase when deceleration torque reduces according to corresponding proportion.
But the synchronous phase of shorter decelerating phase and corresponding prolongation thus consumes less energy.Also there is the slippage of reduction at acceleration phase (energy-conservation equally), because larger slippage causes serious friction and and then causes more energy consumption for this reason.
This displays in the take off data of cross winding bobbin that is relevant with Fig. 4 b to Fig. 4 a, that reel and for this reason required energy:
Know whereby and know, at v
krunder the almost identical average winding speed of ≈ 1.178m/min, BPV=10% deboost phase than time energy consumption relative to deboost phase of BPV=15% than obviously having dropped 6%.
Although describe the device of anti-stacked method of the present invention and correspondence thereof in conjunction with selected embodiment before, technical personnel both can expect other modification, also can expect the combination of described particular implementation.Therefore, such as acceleration torque and deceleration torque not necessarily change according to constant ratio, but also can be optimised independently of one another.
And should point out for the sake of completeness, indefinite article is not got rid of the parts represented with it and can not be provided with multiple.The description of certain parts is not necessarily meaned that its function cannot be able to not be concentrated in unique parts to the function of multiple alternative parts or multiple described parts by dispersion completely.
