The function of the yarn qualities of spinning Y.It is illustrated centered on the yarn qualities function for monitoring in unit control apparatus 10 below.
As shown in figure 4, unit control apparatus 10 in order to carry out the monitoring of yarn qualities, functionally includes monitoring unit 71, stops instruction
Portion 72 and display control section 73 are constituted.
That the spinning Y that the yarn qualities and air flow spinning apparatus 7 for the spinning Y that air flow spinning apparatus 7 generates generate is subject to
There are relativeness between power.Yarn qualities refer to the state of covered fiber cladding heart yarn C.That is, the yarn qualities of spinning Y are core
Yarn C is contained in the yarn qualities in the state of spinning Y.
Illustrate the yarn qualities in the suitable situation of tension value that tension sensor 9 measures below.In heart yarn C and fibre bundle
In the case that F is by tension appropriate, heart yarn C is wrapped by fiber and suitably coats.Such spinning Y has following property.Example
Such as, in stretching yarn Y, heart yarn C and covered fiber part (almost simultaneously) are broken simultaneously.Therefore, the breaking strength of spinning Y
By force.Also, the surface of spinning Y is uniform, and the uniformity for the Y that spins is good.If uniformity is good, with the friction spun yarns such as testing machine Y
When, covered fiber is difficult to remove from heart yarn C, not easily broken.
The tension value that measures in the case where illustrating tension value that tension sensor 9 measures than only generating spinning with fiber bundle F
The yarn qualities of spinning Y in the case where low.In this case spinning Y has heart yarn C generation relaxation, heart yarn C fine from cladding
The prominent tendency circularized of dimension.When stretching such spinning Y, heart yarn C and covered fiber are in respectively different timing fractures.
Therefore, the breaking strength of spinning Y is weak.Also, the surface in the surface of spinning Y other than the part outstanding heart yarn C is uniform
, the deterioration for Y uniformity of spinning is small.Since the deterioration of uniformity is small, when with the friction spun yarns Y such as testing machine, cladding is fine
Dimension is difficult to remove from heart yarn C, not easily broken.
Illustrate the yarn qualities in the case where the tension value surplus that tension sensor 9 measures.In this case spinning Y by
In heart yarn C by be more than necessary tension, therefore have covered fiber cannot bear the elongation of heart yarn C and generate covered fiber stripping
Tendency from (protuberance).In the case where producing the spinning Y of covered fiber removing, heart yarn C and cladding are fine when stretching yarn Y
It ties up in respectively different timing fractures.Therefore, the breaking strength of spinning Y is weak.Also, it since covered fiber is removed, spins
The surface of yarn Y is uneven, and uniformity deteriorates.Since uniformity deteriorates, when with the friction spun yarns Y such as testing machine, cladding is fine
Dimension is easy to remove from heart yarn C, is easy disconnected.
In this way, can monitor the yarn qualities of spinning Y by the tension value that confirmation tension sensor 9 measures.Monitoring unit 71
In order to carry out the monitoring of yarn qualities, judge tension value that tension sensor 9 measures whether in preset quality monitoring
With in reference range.The tension value that the so-called quality monitoring is subject to the spinning Y that reference range is the generation of air flow spinning apparatus 7
Range is the range that the tension value of heart yarn C can be suitably coated by covered fiber.Quality monitoring reference range is according to prison
Depending on the type setting for the spinning Y that portion 71 monitors.The upper limit value (quality monitoring threshold value) and lower limit of quality monitoring reference range
Value (quality monitoring threshold value) can be determined according to the result of spinning Y is actually generated when changing the tension that spinning Y is subject to.Example
It such as, can be according to the lower limit value of the tension value quality-determining monitoring reference range measured when only being generated and spinned with fiber bundle F.
That the tension that the spinning Y that air flow spinning apparatus 7 generates is subject to passes through change feed ratio and heart yarn feedway 40
Power pays portion 51 and pays the tension of heart yarn C and change.Feed ratio is that the preliminary roller of drafting system 6 accumulates dress to 19 revolving speed and yarn
Set the ratio between the revolving speed of 14 yarn accumulation roller 34.For example, feed ratio be " 1 " in the case where, preliminary roller to 19 revolving speed and yarn
The revolving speed for accumulating roller 34 is identical.Feed ratio be " 1.01 " in the case where, yarn accumulate roller 34 rotating ratio preliminary roller to 19 turn
Fast fast, yarn accumulates roller 34 and extracts spinning Y out from air flow spinning apparatus 7 in slightly stretching yarn Y.
The tension value that tension sensor 9 measures becomes high value by improving feed ratio, pays heart yarn C's by improving
Tension becomes high value.On the contrary, the tension value that tension sensor 9 measures becomes low value by reducing feed ratio, pass through drop
The low tension for paying heart yarn C and become low value.
In the case where the tension value specific mass monitoring reference range that tension sensor 9 measures is small, monitoring unit 71 is sentenced
Be set to heart yarn C exist from the prominent yarn qualities for the spinning Y such as circularizing of covered fiber it is abnormal.It is measured in tension sensor 9
In the case that tension value specific mass monitoring reference range is big, monitoring unit 71 is judged to producing covered fiber removing (protuberance) etc.
The yarn qualities of spinning Y exist abnormal.Situation of the tension value that tension sensor 9 measures in quality monitoring reference range
Under, monitoring unit 71 be judged to spinning Y yarn qualities it is suitable.
It can also be in advance by multiple quality monitoring reference range storages corresponding with the spinning type of Y to monitoring unit 71
In, operator selects necessary critical field.Quality monitoring reference range can also pass through operator's input value every time
To set.
Whether monitoring unit 71 contains heart yarn in the spinning Y that also monitoring air flow spinning apparatus 7 generates other than monitoring yarn qualities
C.Whether monitoring unit 71 judges tension value that tension sensor 9 measures in preset monitoring to monitor non-core yarn C
There is useless threshold value or more.It is the tension value that the spinning Y that air flow spinning apparatus 7 generates is subject to that the monitoring, which has useless threshold value, for judgement
There is the threshold value of non-core yarn C.The type for the spinning Y that monitoring has useless threshold value to be monitored according to monitoring unit 71 is set.For example, only with fibre
In the case where tieing up beam F generation spinning, it can also determine that monitoring have useless threshold value according to the tension value of measurement.
In the case where being free of heart yarn C in the Y that spins, the tension value that tension sensor 9 measures is lower.Therefore, it is passed in tension
In the case that the monitoring of tension value deficiency that sensor 9 measures has useless threshold value, monitoring unit 71 is judged to spinning in Y without heart yarn C.
In the tension value that tension sensor 9 measures in the case where monitoring has useless threshold value or more, the Y that is judged to spinning of monitoring unit 71 contains
Heart yarn C.
Monitoring unit 71 allows hand over the monitoring of yarn qualities and has the monitoring of non-core yarn C.The presence or absence of the progress of monitoring unit 71 core
The monitoring of yarn C for example can start to generate spinning Y when progress.It is normal from heart yarn feedway 40 thereby, it is possible to monitor whether
Ground provides heart yarn C.The monitoring for the yarn qualities that monitoring unit 71 carries out can generate after monitoring has non-core yarn C to finish
It is carried out during spinning Y.Monitoring unit 71 can be carried out the monitoring of yarn qualities with timing appropriate and have non-core yarn C as a result,
Monitoring.
Stop instruction unit 72 and be determined as that yarn qualities are deposited in an exceptional case by monitoring unit 71 when monitoring yarn qualities,
Stop the movement in each portion of the spinning units 2 such as air flow spinning apparatus 7, stop the generation of spinning Y.Stop instruction unit 72 supervising
Monitoring unit 71 is judged to making each portion of the spinning units 2 such as air flow spinning apparatus 7 without in the case where heart yarn C when depending on there is non-core yarn C
Movement stop.
Display control section 73 shows the monitoring result of monitoring unit 71 in display unit 74 (referring to Fig.1).For example, display control
The displays such as the tension value of spinning Y that portion 73 processed measures the judging result of yarn qualities and tension sensor 9 are in display unit
In 74.Operator will appreciate that the yarn qualities for the Y that spins, the tension value for having non-core yarn C and the Y that spins etc. as a result,.Setting is aobvious
Show that the position in portion 74 is not confined to headstock 5 as shown in FIG. 1.Display unit 74 also can be set other than headstock 5
Place.
Operator makes to be measured by tension sensor 9 according to the judging result for the yarn qualities being shown in display unit 74
Tension value set in quality monitoring reference range spinning Y spinning conditions.This implementation form passes through change as described above
Become feed ratio and pay in the tension of heart yarn C at least some, can change tension sensor 9 measurement tension value.That is, operation
Personnel change the tension value that tension sensor 9 measures by changing feed ratio and paying the tension of heart yarn C, so as to make yarn
Line mass becomes the yarn qualities for suitably changing spinning Y.
