Technical field
The present invention relates to method and a kind of device that is used to carry out this method of repiece in the spindleless spinning machine (spinning-in), wherein said spindleless spinning machine can carry out manual, semi-automatic or automatic repiece, and be equipped with can reverse drive feed roller.
The situation that the present technique field is present
After interrupting, must on machine, recover the spinning operation.This operation is finished by so-called repiece.The position that repiece is carried out is known as repiece position (spin-in).Compare with the yarn of standard, the repiece position all shows some problems on outward appearance and intensity.In order to eliminate these problems, expensive more machine can use many more special spinning-in operation technology.The feed step that has been found that material is very important for the negative effect of lowering spinning-in operation.So, such as before rotor is cleared up, immediately material being fed to rotor, and under the pulling function of carding roller, upgrade fiber must end (fibre fringe), thereby can improve the quality of position, repiece position.When being subjected to impacting very fast as fiber palpus end by spun yarn, the aforementioned setting will can not worked, and before further carrying out spinning-in operation, fiber is worn once more.Perhaps utilize multiple mode to come from spinning process to remove that initial fiber--utilizes Pneumatic method--usually and feed again after with impaired fiber removal.But this just means the complexity that can obviously increase structure in assembling process.
Essence of the present invention
The objective of the invention is to eliminate most possibly foregoing problems.This can realize by utilize a kind of repiece method in the spindleless spinning machine, wherein said spindleless spinning machine can be manual, semi-automatic or automatic repiece, and be equipped with according to reverse drive feed roller of the present invention, the method is characterized in that, after the feed of ribbon is interrupted, the predetermined length of ribbon being pulled back and can regulate against the feed direction, and after having carried out essential cleaning and repiece time section, when rotor starts, the operation of ribbon feed is with the ribbon of higher speed feed predetermined length, subsequently yarn is carried out spinning-in operation, and after this recover the feed operation of ribbon with the spinning service speed.
Have been found that based on experiment, especially by coming feed ribbon--before spurring--to be optimized with service speed, and need not to consider to be before spinning EO under the situation that fracture takes place, to take place or extra feed one section fibre bar to spinning-in operation.In this case, be preferably in ribbon and stop again ribbon being spurred 1 to 25 millimeter afterwards, meanwhile, preferably carry out described pull operation with the speed that surpasses feed speed 20% at least.Being preferably in rotor clears up rotor immediately before restarting and prepares, when rotor starts or just after rotor starts, with bigger speed feed ribbon, 60% to 110% of the ribbon length that feed length equals to pull back, best, the feed operation of ribbon is finished with the speed that surpasses normal feed speed 20% at least.Consider the carding operation of ribbon, in the moment when arriving initial construction before returning corresponding to ribbon, the actual feed of fiber can take place earlier.By this way, under the condition that can suffer damage fiber must be upgraded by end, and can send into the yarn operation of spinning in high quality not being subjected to long-time combing.After yarn was sent into rotor, the operation of the feed of ribbon can continue to be no more than 1.5 seconds with service speed.Can resist under the situation that height reverses at material, pause a period of time after the be preferably in feed ribbon of predetermined length--must pause and be no more than 1.5 seconds, and restart afterwards at the weighing process of having revised the repiece position (weight course) subsequently--be that the speed that at first increases in other words conj.or perhaps with bigger speed is carried out a period of time ideally, this section period is corresponding to the length of 10-2000cm of spinning, is favourable for good and the ground spinning of big intensity like this.Then, the speed of described ribbon turns back to service speed.
According to repiece method of the present invention also can be used for having at least can reverse drive feed roller or output device and one the spindleless spinning machine of public control system altogether, that is to say that described feed roller can be rotated on both direction, described output device is used to utilize spinning-in system that external control is carried out in feed operation, and described public control system is altogether operated collaborative work with described repiece feed.As be optimized the value that is drawn by test, be preferably in the sensor of at least one operating position assembling on the described spindleless spinning machine, this sensor carries out sensing to the unit weight (length weight) of the yarn that makes, come to go out mean value by several times repiece cycle calculations, generally determine value required when carrying out spinning-in operation, this value is the key property at repiece position, and--and any other textile material--shows obvious difference, and must average the result.
If the weighing process at known repiece position, if then smoothly feed speed is changed, make it little by little start from end and last till its minimum and maximum value smoothly, then it is suitable for revising glibly, and has improved the outward appearance at repiece position.
Description of drawings
Below, when using accompanying drawing, will describe the present invention, wherein
Accompanying drawing 1 schematically shows the operating position in the spindleless spinning machine;
The spinning-in operation chart of the method during accompanying drawing 2 schematically shows according to the present invention; And
Accompanying drawing 3 schematically shows the chart at the spinning-in operation that carries out changing when smooth feed is operated.
Description to example
The spindleless spinning machine includes a plurality of operating positions of arranging successively mutually.The yarn independence manufacturing step of a complexity has all been represented in each operating position.As in accompanying drawing 1 can see, at each place, operating position, extract out from yarn kettle 3 (jug) by the ribbon 1 that fiber 2 is formed, and pass the input nozzle 4 of feeder 5 and be transported in the spinning unit 7 that has collating unit 100, have feed roller 51 on the wherein said feeder 5.Pass the rotor 91 of finished product yarn 26 in spinning unit 7, pull back via separate roller 9 and buffering carrying roller 10 and pass rupture sensors 8.In recent years, not only use rupture sensors 8 continually but also use sensor 19 to come the yarn unit weight is assessed, thereby the yarn that makes is carried out continuous monitoring.Yarn 26 is incorporated into work beam 12 via dispenser 11 from separate roller 9 and buffering carrying roller 10, drives yarn reel 13 by this take up roll 12, and yarn 26 is wrapped on this yarn reel 13.In the space between separate roller 9 and work beam 12, be placed with at yarn 26 spinning apparatus 14 that use the fracture back takes place, this spinning apparatus 14 can be any known type.If feed roller 51 is electronic or the element of electronic control, so at the feed roller 51 of place, any operating position feeder 5 by a stepper motor 6 by a servo-driver or directly drive, wherein said stepper motor 6 couples together by control module 15 and control module 16 and spinning apparatus 14, described control module 16 is arranged in the operating position that is connected with sensor 19 with rupture sensors 8, and described sensor 19 is used for the unit weight of yarn 26 is assessed.
In when, on the spindleless spinning machine of yarn in aforementioned type fracture taking place when, rupture sensors 8 will be sent a signal to control module 16, the latter stops to drive feed roller 51 by control module 15, and immediately or even better after described ribbon 1 travels forward for the last time, for example before spinning unit 7 is cleared up, in described ribbon 1 grade of guiding, make described feed roller 51 reverse motion a period of time, enough yarns 26 of this section period predetermined length of pulling back, the predetermined length of this section corresponds essentially to 1 to 25mm ribbon length.Above-mentioned predetermined length depends on the length and the material type of the staple fibre of ribbon 1, and need selectively as much as possible little, so that the end of ribbon 1 and combing location interval are opened, and the part of attenuation can not enter the front of feed roller 51 by combing simultaneously, otherwise can cause feeding again necessity of ribbon 1.When ribbon 1 is pulled back predetermined length against feed direction, the driving of feed roller 51 is stopped.About above-mentioned situation, it should be noted that the speed of pulling back of ribbon 1 end should surpass 20% of feed service speed at least.After pulling back in the end of ribbon 1, the yarn 26 of pulling back from yarn reel 13 is placed into the spinning apparatus 14 and breaks away from the pipe 60, and cleaning rotor 91.Cleaning rotor 91 must carry out with before carrying out repiece immediately restarting rotor 91.Restart the length that speed/bigger speed feed ribbon 1 is scheduled to when rotor 91 starts or after starting immediately with an increase, this length reaches ribbon 1 60% to 110% of the length of pulling back, and its speed is once more than feeding speed height at least 20%.In this way, in the unshowned roller of collating unit 100, bear fiber again and must hold, and can not make its damage, do further to spin and recover with the service speed feed thereby might make yarn 26 arrive rotors 91 owing to long-time combing.
Can bear under the higher situation about reversing at material, restart feed ribbon 1 short after being 1.5 seconds pause to the maximum, and after repiece, revise after the weight distribution curve at repiece position, with the speed feed material of an increase, carrying out corresponding to 10 to 2000cm long spun yarn time periods, is favourable for obtaining spinning good, sufficient intensity.After this, with normal service speed operation, spinning-in operation finishes ribbon 1 immediately.
In order to improve the quality of carrying out yarn 26 string-up positions according to program of the present invention, to obtain and the normal 26 suitable quality of spinning, special in stopping tractive carding roller under the ribbon situation of 1 feed a period of time, and spinning again to fiber based on good quality, repeatedly in rotor 91, ribbon 1 is processed, and discharged the yarn 26 that repeats to spin.
In order to understand described repiece program better, can be with reference to curve map 2.Alphabetic flag relevant among the figure has gone out each repiece stage, and the feed service speed is labeled as Vp simultaneously, and speed reversal is Vb, and additional feeding speed is Ve, and feeding speed is that Vg and feed postpone T again.But, illustrate that described retardation is not to utilize.Speed reversal preferably is set to greater than Vp 20% at least, and additional feeding speed Ve preferably is set to greater than Vp, and feeding speed depends on concrete test again, and preferably is set to feeding speed Vp and equates.
Under the situation of be equipped with spinning unit at described machine, directly feed being controlled by robot, the method according to this invention also can be used in a bypass robot naturally.
For repiece method according to the present invention, it is unimportant to be used for that aforementioned parameters that the machine of repiece arranges.Obviously, method of the present invention only can also be used for manually control and carry out spinning-in operation, and this is to be conditioned rotation with manual control feed roller at described machine, for example, gets at and carries out by making its extension can be operated personnel.In this case, the moment before operating personnel arrive string-up position also is suitable by artificial additional feed ribbon 1 before clearing up.
