In the present embodiment, weaving unit 2 carries out following control, that is, make the peripheral speed of yarn accumulation roller 41, front roller 20 and middle roller 19 (distance of a bit advancing within per stipulated time on the periphery of roller) different when yarn is weaved and when usually weaving.Particularly, in the present embodiment, the peripheral speed of front roller 20, middle roller 19 and yarn accumulation roller 41 can be controlled independently by each weaving unit 2, therefore carrying out to be suitable for the peripheral speed of weaving usually to generate textile yarn 10 in the weaving unit 2 of usually weaving, to be suitable for the peripheral speed of yarn weaving to generate textile yarn 10 in the weaving unit 2 carrying out yarn weaving.
In the example shown in Fig. 5 A and Fig. 5 B, the peripheral speed of yarn accumulation roller 41 and front roller 20 is fixed when yarn is weaved, and rises gradually when changing.When usually weaving, speed fast when the peripheral speed of front roller 20 and yarn accumulation roller 41 is to weave than yarn becomes fixing again.In Fig. 5 A and Fig. 5 B, the yarn accumulation roller 41 during transformation and the acceleration of front roller 20 are fixing, but also can make acceleration change.
Although different according to the weaving difference of condition, usually when carrying out yarn weaving with weaving speed more than fixing speed, the success rate reduction of the weaving of yarn sometimes.But when reducing weaving speed and weaving, when usually weaving, productivity ratio reduces.Therefore, making peripheral speed increase by such as fig. 5 a and fig. 5b when changing, can boost productivity while the success rate preventing yarn from weaving reduces.
Yarn accumulation roller 41 reels the textile yarn 10 that air textile apparatus 9 generates.Therefore, when the peripheral speed of yarn accumulation roller 41 is faster than the peripheral speed of front roller 20, superfluous tension force can be applied to textile yarn 10, thus textile yarn 10 broken yarn.When the peripheral speed of yarn accumulation roller 41 is slower than the peripheral speed of front roller 20, textile yarn 10 becomes lax.In weaving unit 2, the variation pattern (how peripheral speed changes) of the peripheral speed of the yarn accumulation roller 41 during transformation is identical with the variation pattern of the peripheral speed of front roller 20.In other words, in weaving unit 2, front wheel driving portion 91 and roller drive division 42 is controlled to make yarn accumulation roller 41 with the mode of the peripheral speed phase mutually synchronization of front roller 20.In this manual, can not broken yarn or become lax degree yarn accumulation roller 41 is equivalent to the mode that the peripheral speed of front roller 20 changes " identical variation pattern " with textile yarn 10.
Fig. 5 C is the curve map representing the peripheral speed of yarn accumulation roller 41 and the change of the ratio (the first peripheral speed ratio, feed rate) of the peripheral speed of front roller 20.Preferably the first peripheral speed is than close to 1, to prevent the broken yarn of textile yarn 10 and to relax.But, according to the difference of yam count, weaving speed and the yarn standard etc. as target, there is preferred the first peripheral speed than be greater than 1 or be less than 1 situation.In the example that is shown in fig. 5 c, the first peripheral speed ratio when yarn being weaved is set to and is greater than 1, is set to by the first peripheral speed ratio when usually weaving and is less than 1.
Also can replace the example shown in Fig. 5 A and Fig. 5 B, and the peripheral speed of front roller 20 and yarn accumulation roller 41 is reduced when changing.Also can replace the example shown in Fig. 5 C, and the first peripheral speed ratio when yarn being weaved is set to and is less than 1, is set to by the first peripheral speed ratio when usually weaving and is greater than 1.
In the example shown in Fig. 6 B, the peripheral speed of middle roller 19 is fixing when yarn is weaved, and rises gradually when changing, and time when usually weaving to weave than yarn, fast speed becomes fixing again.
Usually, success rate during yarn weaving also depends on the fibre weight of the fibre bundle 8 supplied to air textile apparatus 9.Therefore, such as, consider following methods: make when yarn is weaved the peripheral speed of rear roller 16 and the 3rd roller 17 change, adjust the fibre weight of the fibre bundle 8 supplied to air textile apparatus 9 thus.But because the peripheral speed of rear roller 16 and the 3rd roller 17 is comparatively slow, even if therefore the variable quantity of peripheral speed is very little, the fibre weight to the fibre bundle 8 of air textile apparatus 9 supply also can change significantly.Its result, the success rate of yarn weaving reduces.In addition, in this case, the fibre weight to the fibre bundle 8 of middle roller 19 supply also changes significantly.Therefore, such as, when the fibre weight of the fibre bundle 8 supplied to middle roller 19 increases, fibre bundle 8 can be suspended on the limiting part 21 that is configured between the 3rd roller 17 and middle roller 19 sometimes.
In the present embodiment, the peripheral speed of front roller 20 is changed with the ratio (the second peripheral speed ratio, main drafting ratio) of the peripheral speed of middle roller 19, adjust the fibre weight of the fibre bundle 8 supplied to air textile apparatus 9.Weaving unit 2 controls front wheel driving portion 91 and midway drive portion 92 in the mode realizing the second peripheral speed ratio specified.Thus, even if when the peripheral speed of front roller 20 or middle roller 19 and set value depart from a little, also can prevent the fibre weight of the fibre bundle 8 supplied to air textile apparatus 9 etc. from changing significantly.
As mentioned above, preferably weave with the speed of weaving faster when usual weaving, unit 2 of therefore weaving makes the speed of front roller 20 and middle roller 19 rise when changing.Second peripheral speed is than different with optimum value when usually weaving when yarn is weaved.Therefore, weaving unit 2 makes the peripheral speed of front roller 20 and middle roller 19 change based on the number etc. of textile yarn 10 in the mode realizing the second best peripheral speed ratio.In the example shown in Fig. 6 C, to make the second peripheral speed when usually weaving than the mode of the second peripheral speed ratio during the weaving that is greater than yarn, the peripheral speed of front roller 20 and middle roller 19 is changed.
Also can replace the example shown in Fig. 6 A and Fig. 6 B and the peripheral speed of front roller 20 and middle roller 19 is reduced when changing.Also can replace the example shown in Fig. 6 C and make the second peripheral speed when usually weaving than be less than yarn weaving time the second peripheral speed ratio.
Like this, in the present embodiment, the peripheral speed of yarn accumulation roller 41, front roller 20 and middle roller 19 is made to change.These peripheral speeds also automatically can set based on inputted weaving condition etc., but also can be set by operator.Operator can specify the peripheral speed of each roller by the value configuration part 6 of board control device 5 being inputted to regulation.
Fig. 7 A to Fig. 7 C is the table representing the content that can be set in configuration part 6.As shown in Fig. 7 A to Fig. 7 C, when weaving by yarn respectively, when changing and usually during weaving, setting item is set.
Setting item when weaving as yarn and when usually weaving, except the peripheral speed of the peripheral speed of yarn accumulation roller 41, the peripheral speed of front roller 20 and middle roller 19, is also provided with the first peripheral speed ratio and the second peripheral speed ratio.Operator selects setting item and the value of input expectation, sets peripheral speed or peripheral speed ratio thus.About the peripheral speed of yarn accumulation roller 41, the peripheral speed of front roller 20 and the first peripheral speed ratio, when determining any two, remaining one is automatically inputted.The peripheral speed of front roller 20, the peripheral speed of middle roller 19 and the second peripheral speed are more identical than also.
As setting item when changing, be provided with each percentage speed variation of yarn accumulation roller 41, front roller 20 and middle roller 19.Percentage speed variation represents the value making change such as the peripheral speed of yarn accumulation roller 41 grade (or changing usual weaving into from yarn weaving with the time of which kind of degree) with the acceleration of which kind of degree.When the first peripheral speed ratio or the second peripheral speed are than when significantly increasing and decreasing, the fibre weight producing broken yarn, Yarn relaxation and fibre bundle 8 as described above such as significantly to increase and decrease at the situation.In order to prevent this situation, in the present embodiment, be configured to about yarn accumulation roller 41, front roller 20 and middle roller 19 and set a percentage speed variation.
In setting item, can input concrete value by operator, also can be the structure that operator selects the grade expected from multiple grade.By setting multiple setting item as described above, correspondingly can reel under appropriate condition with the yam count of textile yarn 10 with as the yarn standard etc. of target.
As described above, spinning frame possesses drafting system 7, air textile apparatus 9 and yarn accumulation roller 41.Drafting system 7 has the multiple drawing rollers comprising front roller 20, carries out drawing-off to fibre bundle 8.Air textile apparatus 9 carries out being twisted by the fibre bundle 8 after drafting system 7 drawing-off and generates the weaving of textile yarn 10.Yarn accumulation roller 41 is at surface winding and the textile yarn 10 that generated by air textile apparatus 9 of accumulation.The peripheral speed of front roller 20 is different with during the usual weaving carried out after this yarn weaving when yarn is weaved.The peripheral speed of yarn accumulation roller 41 is different with when usually weaving when yarn is weaved.In other words, spinning frame, after terminating from yarn weaving, until during weaving starts usually, makes the peripheral speed of front roller 20 rise or reduce, and makes the peripheral speed of yarn accumulation roller 41 rise or reduce.
Thus, the success rate that yarn can not be made to weave reduces and can boost productivity.By not only before changing the peripheral speed of roller 20 also change the peripheral speed of yarn accumulation roller 41, and the broken yarn that produces or Yarn relaxation with the change of the peripheral speed of front roller 20 can be prevented.
In the spinning frame of present embodiment, during till usually weaving playing after terminating from yarn weaving, the variation pattern of the peripheral speed of front roller 20 is identical with the variation pattern of the peripheral speed of yarn accumulation roller 41.
Thereby, it is possible to the broken yarn preventing the change of the peripheral speed of adjoint front roller 20 more reliably and produce or Yarn relaxation.
In the spinning frame of present embodiment, comprise the middle roller 19 of second configuration from downstream at drafting system 7.The peripheral speed of middle roller 19 is different with when usually weaving when yarn is weaved.
By making the peripheral speed of middle roller 19 change, roller 19 such as can be made to change with the draw ratio of front roller 20.Therefore, it is possible to adjust the fibre weight of the fibre bundle 8 carried.Different from the situation being adjusted the fibre weight of fibre bundle 8 by rear roller 16 etc., the increase and decrease amount of the fibre weight of fibre bundle 8 can be suppressed.Therefore, it is possible to prevent fibre bundle 8 to be suspended on limiting part 21.
Above, describe the preferred embodiment of the present invention, but said structure such as can change as described below.
