As shown in figure 4, the unwinding testing number of air ring sensor 19 is weft yarn Y in the case where generating entrance looping mistake
Unwinding testing number that is, " 4 " when normal wefting insertion.In this case, tip sensor 24 and weaving width inner sensor 45 are not examined
Measure weft yarn Y.
In the case where central looping mistake generates, when the unwinding testing number of air ring sensor 19 is weft yarn Y normal wefting insertion
Unwinding testing number that is, " 4 ".In this case, weft yarn Y is not detected in tip sensor 24, but width inner sensor 45 of weaving is right
Weft yarn Y is detected.As described above, central looping mistake is to walk the center of the weaving width TL in the 14a of yarn path in weft yarn
Neighbouring weft yarn Y contacts and is formed the wefting insertion mistake of the looping of weft yarn Y with warp thread.Therefore, it compared with when weft yarn Y normal wefting insertion, spins
The weft examining opportunity for knitting width inner sensor 45 significantly postpones.
In the case where looping mistake in end generates, when the unwinding testing number of air ring sensor 19 is weft yarn Y normal wefting insertion
Unwinding testing number that is, " 4 ".In this case, weft yarn Y is not detected in tip sensor 24, but width inner sensor 45 of weaving is examined
Survey weft yarn Y.As described above, looping mistake in end is separate in the center that weft yarn walks the ratio weaving width TL in the 14a of yarn path
Weft yarn Y contacts and is formed the wefting insertion mistake of the looping of weft yarn Y with warp thread at the position of main burner 22.Therefore, it is passed in weaving width
It is almost the same when the weft examining opportunity of sensor 45 normal with weft yarn Y wefting insertion.
In the case where generating end mistake, moving back when the unwinding testing number of air ring sensor 19 is weft yarn Y normal wefting insertion
Around testing number that is, " 4 ".In this case, the umber of pulse of tip sensor 24 is " 0 ", or when wefting insertion normal for insufficient weft yarn Y
The numerical value of the umber of pulse (such as " 15 ") of tip sensor 24.In addition, as shown in Figure 3A, in end in the case where mistake, weft yarn Y
Relaxation in most cases only weft yarn Y top generate.Therefore, weaving width inner sensor 45 detects weft yarn Y.In addition,
At this point, the top of weft yarn Y reaches the check bit of weaving width inner sensor 45 in the state that the top of weft yarn Y generates relaxation
It sets.Therefore, compared with when weft yarn Y normal wefting insertion, the weft examining opportunity of weaving width inner sensor 45 slightly postpones.
Fig. 5 shows base angle and central looping mistake, end under the weft examining opportunity of weaving width inner sensor 45
Relationship between the mistake of end.As shown in figure 5, regulation number of latitude (such as every 30 latitude) of the control device 16 in the normal wefting insertion of weft yarn Y
The minimum value ISmin and maximum value of the base angle under the weft examining opportunity of weaving width inner sensor 45 are found out in range
ISmax.In addition, control device 16 will be stored as the first threshold from maximum value ISmax plus value made of specified value (such as 10 degree)
Value ISx1.
It is normal in the unwinding testing number of air ring sensor 19 and detect that weft yarn Y's is same in weaving width inner sensor 45
When tip sensor 24 weft yarn Y is not detected in the case where, control device 16 by weave width inner sensor 45 weft examining
Base angle under opportunity is compared with first threshold ISx1.Base under the weft examining opportunity of weaving width inner sensor 45
In the case that angle postpones than first threshold ISx1, the content of generated wefting insertion mistake is judged as that center is risen by control device 16
Enclose mistake.First threshold ISx1 uses as a result, in order to which the content of generated wefting insertion mistake is judged as central looping mistake.
In this way, it is central looping mistake that control device 16, which is inferred as the looping mistake different from entrance looping mistake,.
In addition, in the range of regulation number of latitude of the control device 16 in weft yarn Y normal wefting insertion, to weaving width inner sensor
The average value of base angle under 45 weft examining opportunity is calculated, and its average value is stored as second threshold
ISx2。
It is normal in the unwinding testing number of air ring sensor 19 and detect that weft yarn Y's is same in weaving width inner sensor 45
When tip sensor 24 weft yarn Y is not detected in the case where, control device 16 by weave width inner sensor 45 weft examining
Base angle under opportunity is compared with second threshold ISx2.Machine under the weft examining opportunity of weaving width inner sensor 45
In the case that seat angle is faster than second threshold ISx2, the content of generated wefting insertion mistake is judged as that end is risen by control device 16
Enclose mistake.Second threshold ISx2 uses as a result, in order to which the content of generated wefting insertion mistake is judged as end looping mistake.
In this way, control device 16 is incited somebody to action in the case where the looping mistake different from entrance looping mistake that is, the generation of end looping mistake
The generation position of looping mistake is judged as the generation position of end looping mistake.
In this way, the unwinding testing number in air ring sensor 19 is normal and detects weft yarn in weaving width inner sensor 45
In the case that weft yarn Y is not detected in tip sensor 24 while Y, control device 16 passes through the width inner sensor 45 that will weave
First threshold ISx1, second threshold on weft examining opportunity and the weft examining opportunity of preset weaving width inner sensor 45
Value ISx2 is compared, to infer the generation position of looping mistake.
Base angle under the weft examining opportunity of weaving width inner sensor 45 is faster than first threshold ISx1 and compares
In the case that second threshold ISx2 is slow, the content of generated wefting insertion mistake is judged as end mistake or end by control device 16
Looping mistake.At this point, compared to end looping mistake, end mistake is at just for the content of the wefting insertion mistake actually generated
Become larger than ground.This is because: weft examining opportunity and the latitude of the weaving width inner sensor 45 in the case where end looping mistake
It is almost the same when the normal wefting insertion of yarn Y, in contrast, the weft examining of the weaving width inner sensor 45 in the case where the mistake of end
It is slightly delayed when opportunity more normal than weft yarn Y wefting insertion.
