In the present embodiment, weaving unit 2 carries out following control, that is, in yarn weaving and makes yarn when usually weaving
(any on the periphery of roller is in per stipulated time for the peripheral speed of line accumulation roller 41, front roller 20 and intermediate roller 19
The distance of interior traveling) it is different.In particular, in the present embodiment, front roller can be independently controlled by each weaving unit 2
20, the peripheral speed of intermediate roller 19 and yarn accumulation roller 41, therefore with suitable in the weaving unit 2 usually weaved
Textile yarn 10 is generated in the peripheral speed usually weaved, yarn is suitable in the weaving unit 2 for carrying out yarn weaving and is spun
The peripheral speed knitted generates textile yarn 10.
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 weaved in yarn
When fix, transformation when be gradually increasing.In usual weaving, the peripheral speed of front roller 20 and yarn accumulation roller 41 is than going out
Yarn speed fast when weaving becomes fixed again.Yarn accumulation roller 41 and front roller 20 in Fig. 5 A and Fig. 5 B, when transformation
Acceleration be to fix, but acceleration change can also be made.
Although different according to the difference of weaving condition, it is that typically in the weaving speed more than with fixing speed and is gone out
In the case that yarn is weaved, the success rate of the weaving of yarn sometimes is reduced.But when reducing weaving speed to be weaved, logical
Often productivity reduces when weaving.Therefore, by rising peripheral speed in transformation like that as fig. 5 a and fig. 5b, Neng Gou
The success rate for preventing yarn from weaving improves productivity while reduction.
Yarn accumulation roller 41 winds the textile yarn 10 generated of air textile apparatus 9.Therefore, in yarn accumulation roller
In the case that 41 peripheral speed is faster than the peripheral speed of front roller 20, superfluous tension can be applied to textile yarn 10, thus
10 broken yarn of textile yarn.In the case where the peripheral speed of yarn accumulation roller 41 is slower than the peripheral speed of front roller 20, weaving
Yarn 10 becomes loose.In weaving unit 2, the variation pattern (circumference of the peripheral speed of the yarn accumulation roller 41 when transformation
How speed changes) it is identical as the variation pattern of the peripheral speed of front roller 20.In other words, in weaving unit 2, so that yarn
Driving portion 91 and roller driving portion 42 before the mode that the peripheral speed of accumulation roller 41 and front roller 20 is mutually in step controls.At this
In specification, broken yarn or loose degree will not be become make the circle of yarn accumulation roller 41 and front roller 20 with textile yarn 10
The changed mode of circular velocity is equivalent to " identical variation pattern ".
Fig. 5 C is the ratio between the peripheral speed for indicating yarn accumulation roller 41 and the peripheral speed of front roller 20 (the first circumference speed
Degree ratio, feed rate) variation curve graph.It is preferred that the first peripheral speed ratio is close to 1, to prevent broken yarn and the pine of textile yarn 10
It relaxes.But according to the difference of the count of yarn, weaving speed and yarn standard as target etc., there is preferably the first circumference
The case where speed ratio is greater than 1 or less than 1.In the example that is shown in fig. 5 c, the first peripheral speed ratio when yarn being weaved is set
For greater than 1, the first peripheral speed ratio when by usual weaving is set as less than 1.
Also it can replace the example shown in Fig. 5 A and Fig. 5 B, and make the peripheral speed of front roller 20 and yarn accumulation roller 41
Reduce in transformation.The first peripheral speed ratio when also can replace the example shown in Fig. 5 C, and yarn being weaved is set as being less than
1, the first peripheral speed ratio when by usual weaving is set as being greater than 1.
In the example shown in Fig. 6 B, the peripheral speed of intermediate roller 19 when yarn is weaved to fix, in transformation by
Gradually rise, fast speed becomes fixed again when in usual weaving to weave than yarn.
In general, success rate when yarn is weaved also relies on the fibre weight of the fibre bundle 8 supplied to air textile apparatus 9.
Thus, for example considering following methods: changing the peripheral speed of rear roller 16 and third roller 17 in yarn weaving, thus adjust
The fibre weight of the whole fibre bundle 8 supplied to air textile apparatus 9.But due to the circumference of rear roller 16 and third roller 17 speed
Spend it is slower, therefore even if peripheral speed variable quantity very little, the fibre weight of fibre bundle 8 supplied to air textile apparatus 9 also can
Significantly change.As a result, the success rate of yarn weaving reduces.In addition, in this case, the fiber supplied to intermediate roller 19
The fibre weight of beam 8 also significantly changes.Thus, for example in the increased feelings of fibre weight of the fibre bundle 8 supplied to intermediate roller 19
Under condition, fibre bundle 8 can be suspended to configuration on the limiting component 21 between third roller 17 and intermediate roller 19 sometimes.
In the present embodiment, make the ratio between the peripheral speed of front roller 20 and the peripheral speed of intermediate roller 19 (the second circle
Circular velocity ratio, main drafting ratio) variation, adjust the fibre weight of the fibre bundle 8 supplied to air textile apparatus 9.Weaving unit 2 is with reality
Driving portion 91 and midway drive portion 92 before the mode of second peripheral speed ratio as defined in existing controls.Even if as a result, in front roller 20
Or intermediate roller 19 peripheral speed and set value slightly offset from the case where, can also prevent to air textile apparatus
The fibre weight of the fibre bundle 8 of 9 equal supplies significantly changes.
As described above, it is preferred to be weaved in usual weaving with speed of weaving faster, therefore weaving unit 2 is changing
When increase the speed of front roller 20 and intermediate roller 19.Second peripheral speed ratio is best when weaving when yarn is weaved and usually
Value is different.Therefore, the number of weaving unit 2 based on textile yarn 10 etc. is made in a manner of realizing optimal second peripheral speed ratio
The peripheral speed variation of front roller 20 and intermediate roller 19.In the example shown in Fig. 6 C, so that the second circle when usually weaving
The mode of the second peripheral speed ratio when circular velocity is than being greater than yarn weaving makes the peripheral speed of front roller 20 and intermediate roller 19
Variation.
Also it can replace the example shown in Fig. 6 A and Fig. 6 B and turning the peripheral speed of front roller 20 and intermediate roller 19
It is reduced when change.When the second peripheral speed ratio when also can replace the example shown in Fig. 6 C and making usually to weave is less than yarn weaving
The second peripheral speed ratio.
Like this, in the present embodiment, make the circumference speed of yarn accumulation roller 41, front roller 20 and intermediate roller 19
Degree variation.These peripheral speeds can be also automatically set based on the weaving condition etc. inputted, but also can be by operator
It is set.Operator can input defined value by the configuration part 6 to board control device 5 to specify the circumference of each roller
Speed.
Fig. 7 A to Fig. 7 C is the table for indicating to be set in the content of configuration part 6.As shown in Fig. 7 A to Fig. 7 C, press out respectively
When yarn is weaved, when transformation and usually weaving when setting item is set.
When as yarn weaving and usually weaving when setting item, in addition to the peripheral speed of yarn accumulation roller 41, preceding
Other than the peripheral speed of roller 20 and the peripheral speed of intermediate roller 19, it is additionally provided with the first peripheral speed ratio and the second circumference
Speed ratio.Operator selects setting item and inputs desired value, thus sets peripheral speed or peripheral speed ratio.About yarn
The peripheral speed of line 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 intermediate roller 19 and the second circumference speed
It is also identical to spend ratio.
Setting item when as transformation is provided with each of yarn accumulation roller 41, front roller 20 and intermediate roller 19
Percentage speed variation.Percentage speed variation is to indicate to make with the acceleration of which kind of degree the peripheral speed of yarn accumulation roller 41 etc. to change
The value of (or usual weaving is changed into from yarn weaving with the time of which kind of degree).When the first peripheral speed ratio or the second circle
Circular velocity than generating broken yarn as described above when substantially increasing and decreasing, the feelings such as the fibre weight of Yarn relaxation and fibre bundle 8 substantially increases and decreases
Condition.In order to prevent the situation, in the present embodiment, it is configured to about yarn accumulation roller 41, front roller 20 and intermediate sieve
It draws 19 and sets a percentage speed variation.
In setting item, specific value can be inputted by operator, is also possible to operator and selects from multiple grades
The structure of desired grade.By setting multiple setting items as described above, can with the count of yarn of textile yarn 10 and
Yarn standard as target etc. is correspondingly wound under conditions of appropriate.
