Description
Technical field
The present invention relates to a kind of method of the acceleration control for the bobbin driven roller on the station of weaving loom of producing cross winding bobbin, in this weaving loom, bobbin driven roller drives winding bobbin in frictional engagement mode, and wherein, during winding process, coiling progress is detected.
Background technology
The weaving loom of producing cross winding bobbin is early known; They are normally made up of multiple adjacent settings side by side, same stations, there is the cross winding bobbin that is become large volume with respect to the cop of less thread material by after-combustion, for example on loom, need these cross winding bobbins at the weaving loom in production process downstream.In other weaving looms for example rotor spinning machine, friction-type spinning machine, air-flowing type spinning machine, this winder station is combined to realize the coiling to cross winding bobbin with spinning position.Corresponding spinning position replaces cop or feeding bobbin to feed to yarn.
Cross winding bobbin on station is driven by bobbin driven roller on its side face, and under background herein, this cross winding bobbin refers to winding bobbin.Bobbin driven roller for example can be configured to thread guide drum and during winding process, before yarn is wound up into cross winding bobbin, traverse guide back and forth.Alternatively, utilize the independent thread-carrier yarn that traversed before cross winding bobbin, bobbin driven roller just need not arrange yarn guiding trough like this.
During winding process on automatic winder, the yarn qualities of feeding bobbin is by rejecting yarn defect, and for example slubbing and details are improved.By so-called yarn clearer, the yarn in advancing is detected, in the time finding yarn defect, yarn clearer starting cleaning is rejected yarn defect for this reason.
When there is broken string during bobbin is reeled time, middle cut-off line thus, or make yarn no longer bear winding tension, or cleaner is separated with yarn, this event therefore must be detected, so that the required process of broken yarn is eliminated in starting.Make relevant winder station quit work for this reason, this means, winding bobbin is lifted away from from bobbin driven roller, and not only brakes to quiescence by winding bobbin but also by bobbin driven roller.By loose thread connection procedure, by yarn reparation, winding bobbin or bobbin driven roller must accelerate to winding speed from quiescence.This so-called process of running up is divided into two stages.The first stage of the process that runs up is called soft start and comprises that bobbin driven roller accelerates to for example 100m*min
-1yarn speed.Continue it to accelerate until reach the process of winding speed and be just known as and run up, it is theme of the present invention.
This control winding speed or accelerate to the method for winding speed can be referring to DE42 30 984C2.This Patent Application Publication there are different starting speed characteristic curvees multiple starting assisted instructions be stored in central controller, the slope of this characteristic curve is positioned under limit.Before coiling starts, select the starting assisted instruction of the ascending velocity with steepest, avoided the shortcoming of excessive slip or broken yarn and so on here.
The shortcoming of known method is, operator must from multiple predetermined characteristic curves, select one and this characteristic curve given one not separately for each winding bobbin and definite acceleration/accel.But this predetermined characteristic curve can only cover the affiliated region of these winding bobbins and be not therefore optimal all the time.In addition manually input also existence all the time can make mistakes and select the danger of wrong characteristic curve.
Another defect is, as it illustrates in presents, the continuous process of running up can produce further and skid, and this causes again lap wound.At this, the thread segment on winding bobbin superposes mutually, places outward and occurs protuberance at cop, and these protuberances also can be seen on bobbin side.When further adding man-hour, because kink appears in the thread layers abutting against together, in the time of unwinding subsequently, can carry multiple thread layers secretly, and cause broken yarn.
Summary of the invention
From prior art, the object of the invention is to, further optimize winding process, especially improved winding bobbin being accelerated to this process of winding speed.
According to the present invention, this task solves by a first aspect of the present invention.
The preferred embodiment for the present invention is the theme of other side.
According to a first aspect of the invention, bobbin driven roller is accelerated to predetermined accelerating stage in turn, wherein, not only detect the cireular frequency of bobbin driven roller but also detect the cireular frequency of winding bobbin and both are compared mutually, start described acceleration to next accelerating stage according to the result comparing, and during the process of running up according to the respective roll degree of moving into of winding bobbin the initial of accelerating stage to bobbin driven roller control.
There is like this bobbin driven roller accelerator of skidding that continues to change and be highly suitable for avoiding forming lap wound during running up.The cireular frequency (they are associated with circumferential velocity) of winding bobbin and bobbin driven roller be relatively to start the basis of next accelerating stage and only guaranteed, when winding bobbin is lower than accekeration or when with the velocity contrast of bobbin driven roller, just can start next accelerating stage.
According to the coiling progress of winding bobbin, its diameter, size or the length of yarn of reeling continue to increase, and wherein, the each parameter in these parameters can be as the observed reading of coiling progress.Because moment of inertia equally along with coiling progress increase and increase, so implement the corresponding initial of accelerating stage according to winding speed, to limiting on the one hand skidding between winding bobbin and bobbin driven roller during whole winding process, adopt on the other hand the high value of trying one's best, and then can guarantee to optimize capacity rating.Especially in the time that winding process starts, obtain very high accekeration, this has obviously shortened the time of running up.This is meaningful especially to the automatic winder that will frequently run up owing to will changing cop and clearing.
According to a second aspect of the invention, according to favourable mode, carry out the cireular frequency that described circular acceleration is winding bobbin and the product of diameter during always in the circular acceleration threshold value lower than winding bobbin in the next accelerating stage of bobbin driven roller during the process of running up initial.Described threshold value reduces along with the increase of the coiling progress of winding bobbin." accelerating stage " should be understood under meaning of the present invention, and bobbin driven roller accelerates as far as possible at first stage, desirable for to accelerate to predetermined speed with peak acceleration, keeps subsequently this velocity stage constant, until start the acceleration phase of next accelerating stage.Because the moment of inertia of winding bobbin rises along with the increase of coiling progress, thus must feasible accelerating when starting in the time approaching winding process and finish during the process that runs up slowly, to avoid excessive slip.
According to the third and fourth aspect of the present invention, in embodiment of the present invention, for the winding bobbin circular acceleration threshold value that the respective roll degree of moving into of winding bobbin distributes can the moment of inertia relevant to coiling progress based on winding bobbin be determined, or on multiple stations for example, determine by rule of thumb and after this as the foundation of other stations.The threshold value that is used for the next accelerating stage that starts bobbin driven roller can be determined or determine according to the experiment of winding process by calculating.
The moment of inertia I of cheese calculates in the following way:
The volume V of hollow cylinder is calculated as follows:
V=π * h* (r
bobbin 2* r
spool 2), wherein, h represents height.
The quality m of bobbin is calculated as follows:
M=ρ * V, wherein, ρ is density.
Obtain thus the following formula of moment of inertia I:
According to a fifth aspect of the invention, last 1/3rd places of the process that runs up in an accelerating stage are measured until reach value that the circumferential velocity of winding bobbin and bobbin driven roller is synchronous or the required time of adjustable value wherein of representing, when when there is target offset in interval time rating, change accelerating stage initial of the follow-up process that runs up, so that it is corresponding to another coiling progress of winding bobbin.By this way determine the so-called time value that runs up be an index, instruction approach run up finish time occur how much skid and can infer consider make quality can not decline feasible acceleration/accel.To until reach by winding bobbin and represent that value that the circumferential velocity of bobbin driven roller is synchronous or required time and the expectation value of adjustable value wherein compare, can be in the scope of control loop to the winding bobbin circular acceleration for starting accelerating stage calculate threshold value or by rule of thumb definite threshold value proofread and correct.At this, only for example, in the time that the especially particular event due to winder station (fault in process of waxing or unstable) has deviation with determined standard value, just Intervention.
According to a sixth aspect of the invention, according to advantageous manner, reach in last accelerating stage of final winding speed at bobbin driven roller, determine to reach by winding bobbin and represent value that the circumferential velocity of bobbin driven roller is synchronous or required time of adjustable value wherein, this is because can determine failure-free value in the time that the process of running up finishes, and can under minimum production loss, carry out required correction.In this accelerating stage, owing to proceeding to final production speed, for example do not exist and due to the unnecessary prolongation in intermediary, definite process time that runs up is exerted an influence.In addition, the interruption that may mislead result runs up and also cannot be detected, thereby also cannot be used for regulating acceleration.
According to a seventh aspect of the invention, when exceeding time rating when interval, postpone the initial of accelerating stage with predetermined value, skid thereby avoid producing.Therefore to the adjusting of accelerating stage initial point corresponding to higher coiling progress.Similarly, according to an eighth aspect of the invention, when being less than time rating when interval, shift to an earlier date the beginning of accelerating stage with predetermined value, run up the time thereby shorten, thereby corresponding to lower coiling progress.
In favourable embodiment, according to a ninth aspect of the invention, duplicate measurements interval time rating, is considering that in current winding condition situation, enforcement is adjusted afterwards.This measure has been guaranteed can between different adjustment, frequently not switch because of so-called abnormal observed reading.But only consider safe deviation.
Brief description of the drawings
Below in conjunction with the automatic winder station explanation the present invention who schematically illustrates.
Wherein:
Fig. 1 is the schematic diagram of automatic winder station;
Fig. 2 is the run up value diagram of curves relevant with winding bobbin diameter.
Detailed description of the invention
Fig. 1 is illustrated on each station from feeding bobbin 1, unwinding yarn 2 on the cop of especially producing on ring spinner, and yarn 2 is winding to cross winding bobbin 3, for example, on conical cross winding bobbin.
The cross winding bobbin 3 that utilizes unshowned, pivotable bobbin bank to keep is close to bobbin driven roller 4, is especially close to so-called thread guide drum, utilizes thread guide drum rotation cross winding bobbin 3 and yarn 2 to be fed to cross winding bobbin 3 vertically with traversing.But also can expect within the scope of the present invention the Yarn lateral-movement device of other types, for example so-called finger-type thread-carrier.
Yarn 2 (yarn that it normally forms on ring spinner) at feeding bobbin 1 to the sensor through thread-carrier 5, controlled yarn tension tensioner 6, yarn tension sensor 9 and yarn clearer 8 forms on the path of cross winding bobbin 3.Yarn tensioner 6 applies predetermined gripping power to the yarn 2 of advancing.Yarn clearer 8 is monitored fault, especially slubbing or the details of the yarn 2 of advancing.
In yarn travel path, be provided with at yarn tension sensor 9 rears the device 14 of waxing, perhaps also have another thread-carrier 10.The utilization device 14 coated with paraffin particle on yarn of waxing, they have improved advancing of yarn and sliding properties, this especially in after-treatment process, for example braiding and knitting in very meaningful.
The bobbin driven roller 4 of each station utilizes the CD-ROM drive motor 12 of self to drive, and it is furnished with especially drum motor output stage 13 of speed adjustment.The control of drum motor output stage 13 is implemented according to for example yarn tension of the specific parameter of station by station computing machine 11.The unshowned central computer of automatic winder is for example connected with the station computing machine 11 of a large amount of stations by bus.
In the time there is intolerable yarn defect, yarn 2 separation interrupting advancing by yarn clearer cutting have bug yarn line segment., winding bobbin 3 is lifted away from from bobbin driven roller 4 for this reason, not only brakes to quiescence by winding bobbin 3 but also by bobbin driven roller 4.Existing two yarn and thread heads utilize known splicing mechanism 7 connected with each other at present.Afterwards, winding bobbin 3 dropped on bobbin driven roller 4 again and accelerate bobbin driven roller 4.Until yarn speed is in for example 100m*min
-1time, carry out so-called soft start, carry out afterwards according to the process that runs up of the present invention.In an accelerating stage, bobbin driven roller 4 is accelerated to predeterminated level and remains on this level.Circumferential velocity to winding bobbin 3 or circular acceleration detect simultaneously, that is, and and circumferential velocity slope of a curve.If the circumferential velocity of winding bobbin 3 for example, lower than the threshold value matching with the diameter of winding bobbin 3, starts next accelerating stage.If bobbin driven roller 4 has reached final winding speed, no longer accelerate, and detect winding bobbin 3 and reach equally the required time of its final winding speed.This run up time and the so-called time threshold that runs up are compared.If run up, time threshold is for example defined as 900ms and 3 times of running up of winding bobbin have been used 1000ms, reduces the follow-up acceleration/accel running up, and that is to say, postpones the initial of accelerating stage.Detect the time value that runs up completing after running up at every turn.
In order not change the threshold value of accelerating stage and can constantly not switch back and forth between the different adjustment at accelerating stage after to run up separately at every turn, multiple determined time of running up of the process that runs up is gathered.So just can select reliably the threshold value of accelerating stage, and there will not be each abnormality detection value to have a negative impact to threshold value.
Fig. 2 exemplarily shows the changes of threshold of the acceleration/accel of winding bobbin 3, and this threshold value starts the next accelerating stage of bobbin driven roller 4, and it depends on the diameter of winding bobbin.The acceleration rate threshold of winding bobbin 3 is shown on coordinate.Abscissa illustrates the diameter of winding bobbin, starts from the diameter of sky bobbin.In order to start winding process, first obtain a stage, wherein, in the time that the acceleration/accel of winding bobbin 3 is also relatively high, start the next accelerating stage of bobbin driven roller 4.Because the inertia of winding bobbin 3 is relatively low in certain time interval, thus this be in diameter the situation of the most about 110mm can keep the higher initiation threshold of circular acceleration.Along with the diameter of winding bobbin 3 increases, accekeration reduces.In the time that acceleration rate threshold has reached low-level, the stage that there will be within the scope of the present invention threshold value to remain unchanged in the time that winding process finishes.This shows, the present invention does not require the threshold value that must reduce (regularly) acceleration/accel during whole winding process.
The circular acceleration threshold value of winding bobbin 3 is not only relevant with inertia, and is subject to and a batch impact for relevant parameter (for example waxing).The curvilinear motion of each batch the value of running up is stored in station computing machine or central computer, thereby can be used as again basis in the time running into next same batch.
