As shown in the double dot dash line of (a) in Fig. 4, in a balladeur train 15 there are multiple Rove Packages 12,
There are ideal distribution of weight.It is shown in solid such as (a) in Fig. 4 but if deviation of weight σ becomes larger.If moreover, weight
Deviations become larger, then the first index (process capability index Cp) becomes less than 1.0.In the case where the first index is less than 1.0,
There are between multiple Rove Packages 12 in one balladeur train 15, there are difference in the weight of Rove Package 12, are in
The state that the small Rove Package 12 of the big Rove Package 12 of weight, weight is mixed in a balladeur train 15.In this embodiment party
In formula, in the case where the first index is less than 1.0, arithmetic unit 31 is determined as that deviation of weight σ is abnormal.
In addition, as shown in the double dot dash line of (b) in Fig. 4, if relative to ideal distribution of weight, weighed average μ's
Bias becomes larger, then distribution of weight is for example as shown by the solid line, and the second index becomes less than 1.0.It is less than 1.0 feelings in the second index
Under condition, the weighed average μ of Rove Package 12 is larger relative to median deviation.Specifically, between Rove Package 12
Weight difference it is smaller, but the weight of each Rove Package 12 relative to median deviate it is larger.In the present embodiment,
In the case that two indexes are less than 1.0, it is determined as that the bias of weighed average μ is abnormal.
Moreover, in the case where being determined as deviation of weight σ abnormal (1.0 the first indexes of >), arithmetic unit 31 is to fly frame
11 outputs and disposition 1 relevant signal of warning.Disposition warning includes being allowed to become for correcting the gravimetric anomaly of Rove Package 12
For normal countermeasure.There are many disposition warnings, correspondingly pre-saves with the first index and the second index and is filled in storage
Set 31a.
Arithmetic unit 31 in the case where being determined as deviation of weight σ abnormal (1.0 the first indexes of >), with the judgement build by selection
The disposition warning 1 for having found correspondence, by with disposition 1 relevant signal of warning to the Rove Package being determined to will be produced
12 fly frame 11 exports.Then, fly frame 11 makes display 11a display disposition warning 1.Therefore, in the present embodiment, transport
Device 31 is calculated to constitute to for making deviation of weight σ become the apparatus for predicting that normal countermeasure is inferred.
On the one hand, it is abnormal (1.0 the first indexes of >) in deviation of weight σ, can enumerates, the difference of sliver weight
It is not multiple, in rove production process by reeling roving in the bobbin during the cut-off broadwise fracture of rove, be wound in
Cut-off broken yarn is multiple before bobbin.For example, in multiple drafting systems of fly frame, draw roll in specific spindle
In the case of being partially formed abrasion, the amount of tension of sliver is different from other spindles, and sliver weight shift can lead to Rove Package 12
Weight difference.
If in addition, there is broadwise fracture, broken yarn, fly frame stops, connecing yarn, be then again started up fly frame.For depositing
In having multiple spindles multiple broadwise fracture, broken yarn spindle be wound in the rove amount hair of bobbin compared with other spindles
It changes dynamic, as a result, leading to the weight difference of Rove Package 12.
In order to eliminate these, need to inhibit the difference of sliver weight, broadwise fracture, broken yarn it is multiple.In present embodiment
In, thus it is speculated that the difference of sliver weight is the main reason for causing deviation of weight σ abnormal, as disposition warning 1, such as (a) in Fig. 6
It is shown, propose to promote user implement to for sliver by yarn road component (the specifically draw roll in drafting system) save from damage
Countermeasure.
On the other hand, in the case where being determined as bias abnormal (1.0 the second indexes of >) of weighed average μ, operation
Device 31 selects to establish the disposition warning 2 of correspondence with the judgement, and 2 relevant signals will be alerted with disposition to fly frame 11
Output.Fly frame 11 makes display 11a show and disposition 2 relevant information of warning in input signal.Therefore, in this implementation
In mode, arithmetic unit 31 is constituted to for making the bias of weighed average μ become what normal countermeasure was inferred
Apparatus for predicting.
The bias of the weighed average μ of Rove Package 12 can enumerate following situation:Because of the setting mistake of drafting system
And cause heavier without exception or relatively light without exception from the weight of the stretched rove of sliver;Lead to sliver because of the setting mistake of drawing frame
Weight is heavier without exception or relatively light without exception.It is bad in order to eliminate these, need to inhibit the same property of sliver weight to change, rove weight
Same property change.In the present embodiment, the case where sliver weight being deviateed relative to desirable weight datum value speculates
The main reason for cause the bias of weighed average μ abnormal, as shown in (b) in Fig. 6, proposes to promote as disposition warning 2
Implement the countermeasure of the setting check of the drawing frame to manufacturing sliver into user.
In addition, deviation of weight σ abnormal (1.0 the first indexes of >) and weighed average μ bias it is abnormal (1.0
The second indexes of >) in the case of, arithmetic unit 31, and will be relevant with disposition warning 1 first of all for making deviation of weight σ become normal
Signal is exported to fly frame 11.Then, deviation of weight σ becomes normal, but as long as the exception of the bias of weighed average μ does not disappear
It removes, arithmetic unit 31 will export to fly frame 11 in order to make the bias of weighed average μ become normal and dispose warning 2
Relevant signal.
Moreover, when in display 11a display disposition warning 1 or disposition warning 2, user takes for disposition warning
Countermeasure thus enables that the gravimetric anomaly of Rove Package 12 becomes normal.
In addition, also inputting the number for dysponderal spindle occur to arithmetic unit 31.Occur it is dysponderal
In the case that spindle is detected for several times at specific balladeur train 15 within the short time (for example, half a day), arithmetic unit 31 is to having
The fly frame 11 of the spindle exports and the relevant signal of dysponderal spindle occurs.Fly frame 11 makes in input signal
Display 11a shows and the relevant information of dysponderal spindle occurs.
In this case, being shown " take place frequently gravimetric anomaly at No. zero spindle of zero row of fly frame 11 " in display 11a
Such warning.
