Unit control apparatus 10 controls the action in each portion of spinning unit 2.Unit control apparatus 10 has the function of the yarn qualities monitoring the spinning Y generated.Be described centered by yarn qualities function for monitoring below in unit control apparatus 10.As shown in Figure 4, unit control apparatus 10, in order to carry out the supervision of yarn qualities, functionally comprises monitoring unit 71, stops instruction unit 72 and display control unit 73 to form.
Relativeness is there is between the tension force that the spinning Y that the yarn qualities of the spinning Y that open end spinning apparatus 7 generates and open end spinning apparatus 7 generate is subject to.Yarn qualities refers to the state of the coated heart yarn C of covered fiber.That is, the yarn qualities of Y of spinning be heart yarn C be contained in spinning Y state under yarn qualities.
The following describes tension pick-up 9 measure tension value suitable when yarn qualities.When heart yarn C and fiber bundle F are subject to suitable tension force, it is suitably coated that heart yarn C is wrapped by fiber.Such spinning Y has following character.Such as, when stretching yarn Y, the while of heart yarn C and covered fiber part, (almost simultaneously) ruptures.Therefore, the fracture strength of this spinning Y is strong.Further, the surface uniform of this spinning Y, the uniformity of spinning Y is good.If uniformity is good, then time with friction spun yarn Y such as testing machines, covered fiber is difficult to peel off from heart yarn C, not easily broken.
The yarn qualities of the spinning Y when tension value that tension pick-up 9 is measured is lower than the tension value measured when only generating spinning by fiber bundle F is described.In this case spinning Y has heart yarn C and produces lax, heart yarn C protrudes annular from covered fiber tendency.When such spinning Y that stretches, heart yarn C and covered fiber rupture in timings different separately.Therefore, the fracture strength of this spinning Y is weak.Further, the surface beyond the part that in the surface of this spinning Y, heart yarn C gives prominence to is uniform, and the deterioration of spinning Y uniformity is little.Because the deterioration of uniformity is little, therefore when with friction spun yarn Y such as testing machines, covered fiber is difficult to peel off from heart yarn C, not easily broken.
Yarn qualities when the tension value surplus that tension pick-up 9 measures is described.In this case spinning Y is subject to exceeding necessary tension force due to heart yarn C, therefore has covered fiber and can not bear the elongation of heart yarn C and produce the tendency that covered fiber peels off (protuberance).When creating the spinning Y that covered fiber is peeled off, when stretching yarn Y, heart yarn C and covered fiber rupture in timings different separately.Therefore, the fracture strength of this spinning Y is weak.Further, because covered fiber is peeled off, the surface of the Y that therefore spins is uneven, homogeneity deteriorates.Due to homogeneity deteriorates, therefore when with friction spun yarn Y such as testing machines, covered fiber is easily peeled off from heart yarn C, easily breaks.
Like this, by confirming that the tension value of tension pick-up 9 measurement can monitor the yarn qualities of spinning Y.Monitoring unit 71, in order to carry out the supervision of yarn qualities, judges tension value that tension pick-up 9 measures whether in the quality monitoring reference range preset.This quality monitoring reference range so-called is the scope of the tension value that spinning Y that open end spinning apparatus 7 generates is subject to, and is can the scope of the suitably tension value of coated heart yarn C by covered fiber.The kind setting of the spinning Y that quality monitoring reference range monitors according to monitoring unit 71.The actual result generating spinning Y in tension force limit that the higher limit (quality monitoring threshold value) of quality monitoring reference range and lower limit (quality monitoring threshold value) can be subject to according to limit change spinning Y decides.Such as, can according to the lower limit of the tension value quality-determining supervision reference range measured when only generating spinning by fiber bundle F.
The tension force that is subject to of spinning Y that open end spinning apparatus 7 generates is paid portion 51 by the tension force of change feed ratio and heart yarn feedway 40 and is paid the tension force of heart yarn C and change.Feed ratio is the preliminary roller of drafting system 6 accumulates the rotating speed of roller 34 ratio to the rotating speed of 19 and the yarn of yarn accumulation device 14.Such as, when feed ratio is " 1 ", preliminary roller is identical with the rotating speed that yarn accumulates roller 34 to the rotating speed of 19.When feed ratio is " 1.01 ", the rotating ratio preliminary roller that yarn accumulates roller 34 is fast to the rotating speed of 19, and yarn accumulates roller 34 limit and extracts spinning Y out from open end spinning apparatus 7 in stretching yarn Y limit a little.
The tension value that tension pick-up 9 is measured becomes high value by improving feed ratio, becomes high value by improving the tension force paying heart yarn C.On the contrary, the tension value that tension pick-up 9 is measured becomes low value by reducing feed ratio, pays the tension force of heart yarn C and become low value by reduction.
When the tension value specific mass supervision reference range that tension pick-up 9 measures is little, monitoring unit 71 is judged to be that heart yarn C protrudes annular from covered fiber and waits the yarn qualities of spinning Y to exist extremely.When the tension value specific mass supervision reference range that tension pick-up 9 measures is large, monitoring unit 71 is judged to be that creating covered fiber peels off the yarn qualities existence of spinning Y such as (protuberances) extremely.The tension value that tension pick-up 9 measures is in quality monitoring reference range, monitoring unit 71 is judged to be that the yarn qualities of spinning Y is suitable.
Also can be stored in monitoring unit 71 by multiple quality monitoring reference range corresponding with the kind of spinning Y in advance, operating personnel select necessary critical field.Quality monitoring reference range also can be set by operating personnel's input value at every turn.
Whether monitoring unit 71, except monitoring yarn qualities, also monitors in the spinning Y that open end spinning apparatus 7 generates containing heart yarn C.Monitoring unit 71, in order to monitor non-core yarn C, judges whether the tension value that tension pick-up 9 measures has more than useless threshold value in the supervision preset.This supervision has useless threshold value to be the tension value that is subject to of spinning Y that open end spinning apparatus 7 generates, for determining whether the threshold value of heart yarn C.Monitor the kind setting of the spinning Y having useless threshold value to monitor according to monitoring unit 71.Such as, when only generating spinning by fiber bundle F, also can determine that supervision has useless threshold value according to the tension value measured.
In spinning Y containing heart yarn C, the tension value step-down that tension pick-up 9 is measured.Therefore, when the tension value deficiency supervision that tension pick-up 9 measures has useless threshold value, monitoring unit 71 is judged to be in spinning Y not containing heart yarn C.When the tension value that tension pick-up 9 measures has more than useless threshold value in supervision, monitoring unit 71 is judged to be that spinning Y is containing heart yarn C.
Monitoring unit 71 can switch the supervision of yarn qualities and have the supervision of non-core yarn C.What monitoring unit 71 was carried out has the supervision of non-core yarn C such as to carry out when starting generation spinning Y.Thereby, it is possible to monitor whether normally provide heart yarn C from heart yarn feedway 40.The supervision of the yarn qualities that monitoring unit 71 is carried out after supervision has non-core yarn C to finish, can be carried out in the process generating spinning Y.Thus, monitoring unit 71 can be carried out the supervision of yarn qualities with suitable timing and have the supervision of non-core yarn C.
Stopping instruction unit 72 to be judged to be that yarn qualities is deposited in an exceptional case when monitoring yarn qualities by monitoring unit 71, making the action in each portion of spinning unit such as open end spinning apparatus 7 grade 2 stop, the generation of spinning Y is stopped.When stopping instruction unit 72 monitoring unit 71 when supervision has non-core yarn C to be judged to not contain heart yarn C, the action in each portion of spinning unit such as open end spinning apparatus 7 grade 2 is stopped.
The monitoring result of monitoring unit 71 is presented in display part 74 (with reference to Fig. 1) by display control unit 73.Such as, the tension value etc. of spinning Y that the judged result of yarn qualities and tension pick-up 9 measure by display control unit 73 is presented in display part 74.Thus, operating personnel can grasp the yarn qualities of spinning Y, have the tension value etc. of non-core yarn C and spinning Y.The position arranging display part 74 is not confined to headstock 5 as shown in FIG. 1.Display part 74 also can be arranged on the place beyond headstock 5.
Operating personnel make the tension value measured by tension pick-up 9 in quality monitoring reference range, set the spinning conditions of spinning Y according to the judged result of the yarn qualities be presented in display part 74.This embodiment as described above by change feed ratio and pay in the tension force of heart yarn C at least certain, can change tension pick-up 9 measure tension value.That is, operating personnel change the tension value that tension pick-up 9 is measured by change feed ratio and the tension force paying heart yarn C, thus yarn qualities can be made to become the yarn qualities changing the Y that spins suitably.
With Fig. 5, feed ratio be described and pay the relation between the tension force of heart yarn C and yarn qualities.When feed ratio low and pay the tension force of heart yarn C little (" NG1 " region in Fig. 5), the tension value that tension pick-up 9 is measured is little.In this case, there is generation heart yarn C protrudes the spinning Y of annular tendency from covered fiber.When feed ratio high and pay the tension force of heart yarn C large (" NG2 " region in Fig. 5), the tension value that tension pick-up 9 is measured is large.In this case, there is the tendency generating the spinning Y that covered fiber is peeled off from heart yarn C.Fig. 5 " OK " region representation spinning Y tension value in quality monitoring reference range, yarn qualities suitable time feed ratio and the tension force paying heart yarn C between relation.
Operating personnel look at the judged result be presented in display part 74, set feed ratio and the tension force paying heart yarn C with generating the spinning Y of suitable yarn qualities.The setting of feed ratio can be undertaken by the operating portion of such as operating personnel's manipulator member control apparatus 20.Such as, relative to preliminary roller to 19 rotating speed and change the rotating speed of motor 36 driving yarn to accumulate roller 34, thus can feed ratio be changed.When preliminary roller is driven by the drive source be provided separately 19, the rotating speed of this drive source also can be changed.The adjustment dial 62 that the setting of paying the tension force of heart yarn C can pay portion 51 by the tension force of operating personnel's operation setting in heart yarn feedway 40 carries out.Yarn accumulation device 14 and tension force pay the configuration part that the spinning conditions setting spinning Y is worked in portion 51.
