It is logical.Thread guidance 2 is the component in a manner of keeping weft yarn consistent with the central axis T of accelerating tube 1 and be conveyed to guide weft yarn.
As shown in Figure 1, accelerating tube 1 has tapered portion 1a and straight line portion 1b.Tapered portion 1a is formed as internal diameter from upstream side court
Downstream and continuously become larger.In addition, the tilt angle of the inner surface of tapered portion 1a is θ.In addition, straight line portion 1b and taper
The downstream side of portion 1a connects, and by from upstream side throughout downstream side have the same diameter in a manner of and be formed as the shape of straight line.
Accelerating tube 1 carries out jet injection to weft yarn from the front end 1c in downstream side.In addition, the length of straight line portion 1b is A, accelerating tube 1
Overall length is L.
In addition, as shown in Fig. 2, air-jet loom 100 has wire portion 7.It is formed in wire portion 7 and extends along wefting insertion direction Y
Tunnel 7a.Moreover, weft yarn 20 is sprayed from the front end 1c of accelerating tube 1 by jet, along the central axis T of accelerating tube 1 in tunnel
It is gone at express speed in 7a to carry out wefting insertion.
Also, as shown in figure 3, being divided between the entrance of the tunnel 7a of the front end 1c and wire portion 7 of accelerating tube 1

The circle E of the dotted line shown shows the position of accelerating tube 1.
Next, being illustrated using the determining method of the range of the length A of the straight line portion 1b of Fig. 5~9 pair accelerating tube 1.
Firstly, indicating weft yarn 20 with 2 particles P1, P2 and with simplified model as shown in Fig. 5 (A), Fig. 5 (B).Moreover,
The yarn speed of the arbitrary point P1 of weft yarn 20 is set as U1, the yarn speed of the front end P2 in the downstream side of weft yarn 20 is set as U2.Here, drawing
When latitude starts, the yarn speed U1 of point P1 is faster than the yarn speed U2 of point P2.Moreover, as shown in Figure 5A, at the beginning of weft insertion, before weft yarn 20
When end P2 is located at position identical with the front end 1c of accelerating tube 1, D1 is divided between 2 particles P1, P2 of weft yarn 20.It connects down
Come, as shown in Figure 5 B, in the entrance for the tunnel 7a that the front end P2 of weft yarn 20 reaches wire portion 7,2 particle P1 of weft yarn 20,
The interval of P2 is reduced to D2 from D1.Therefore, bending is generated near the front end in the downstream side of weft yarn 20.
Bending is generated in weft yarn 20 as such, then as shown in Figure 6A, generates bending in weft yarn 20.As shown in Figure 6A, it will roll over
The length of the weft yarn 20 of bight portion is set as bending length S.In addition, being by the front end P2 from the central axis T of accelerating tube 1 to weft yarn 20
Distance only is set as bending distance h.Moreover, as shown in Figure 6B, becoming length substantially identical with bending length S in bending distance h
When spending, i.e., yarn is with right-angle bending, and when becoming substantially identical as bending length S close to amount of particle P1 and P2, bending distance h is most
Big value hmax.In addition, the generation of such bending is mainly after the wefting insertion of air-jet loom 100 just starts, i.e., pressure rises
Initial stage the phenomenon that.
Here, if being defined as yarn speed ratio q=U1/U2, relational expression below is set up.In addition, by the front end P2 of weft yarn 20
Time until reaching the entrance of the tunnel 7a of wire portion 7 is set as t2.In addition, yarn speed U1/U2 is for example by entering D1=
During 20mm air complete work, i.e., yarn relative to the increment of the kinergety of energy ratio and found out.
[formula 2]
S=(U1-U2) * t2
=U2* (q-1) * (c1/U2)
=(q-1) * c1
Here, in the case where the wall of the front end P2 of the weft yarn of the bending 20 and tunnel 7a of wire portion 7 contacts, in the fabric
A possibility that generating latitude knot gets higher.Therefore, the item that the front end P2 of the weft yarn 20 of bending is not contacted with the wall of the tunnel 7a of wire portion 7
Part is indicated by relational expression below.
[formula 3]
C2 > hmax=S=(q-1) * c1
If being deformed for yarn speed ratio q, relationship below is set up.
[formula 4]
q<(c2/c1)+1
Therefore, if yarn speed ratio q is smaller than maximum value qmax=(c2/c1)+1, the front end P2 of the weft yarn 20 of bending not with lead
The wall of the tunnel 7a in line portion 7 contacts.That is, the yarn speed ratio q that the front end P2 of the weft yarn 20 of bending is not contacted with wire portion 7
Condition, i.e. yarn speed ratio q maximum value qmax dependent on wire portion 7 and accelerating tube 1 front end 1c positional relationship.
Next, in Fig. 7, the deduction formula f (L, A/L, θ) that is obtained by multivariate analysis and the ratio A/L that finds out and promote
The relationship of power ratio p is by pictorialization.Than A/L indicate straight line portion 1b length A relative to accelerating tube 1 overall length L ratio.Here, it pushes away
The weft yarn 20 of per unit length is come from when tilting into the inner surface that power ratio p is tapered portion 1a and form tilt angle theta
The ratio between the propulsive force being compared when spraying propulsive force and the tilt angle theta of fluid=0.The minimum value pmin root of propulsive force ratio p
The mesh during the unlatching of the valve of compressed air is supplied according to the pressure of the compressed air supplied to main burner 10 or to main burner 10
Scale value and be determined.It is than A/L when the propulsive force ratio p of accelerating tube 1 is minimized pmin=1.2 according to the chart of Fig. 7
0.76。
In addition, in fig. 8, passing through the ratio A/L and yarn that deduction formula f (L, A/L, θ) is found out obtained from multivariate analysis
The relationship of speed ratio q is by pictorialization.Here, the maximum in the case where yarn speed ratio q takes as distance c1=20mm, distance c2=3mm
It is 0.13 than A/L when value qmax=1.15.
Also, in Fig. 9, the evaluation function F0 of ratio A/L when diagrammatically showing L=240mm, θ=0.10.Compare A/
The evaluation function F0 of L is 0~1 dimensionless number, is indicated by following formula.In addition, the evaluation function F1 of propulsive force ratio p is phase
F1=0 is set as when propulsive force ratio p is less than minimum value pmin for the ratio of any sufficiently big value of propulsive force ratio p.In addition,
The evaluation function F2 of yarn speed ratio q=U1/U2 is the ratio of any sufficiently big value relative to yarn speed ratio q, is greater than most in yarn speed ratio q
Big value qmax is big, is set as F2=0.
[formula 5]
F0=(F1*F2) ^0.5
Therefore, according to Fig. 9, in L=240, θ=0.10, than the value for the range that A/L is 0.13 < ratio A/L≤0.76.
Accordingly, the accelerating tube 1 of the air-jet loom 100 of present embodiment has tapered portion 1a, the downstream side with tapered portion 1a
Connect the straight line portion 1b of setting.Here, the yarn speed ratio q of weft yarn by the overall length L of accelerating tube 1, straight line portion 1b length A relative to
Relationship between the tilt angle theta of the inner surface of the ratio A/L and tapered portion 1a of the overall length L of accelerating tube 1 and found out.Separately
Outside, for L, the value than A/L and θ, the maximum value qmax of yarn speed ratio q, which is decided to be, to be utilized from the downstream side of accelerating tube 1
Front end to wire portion 7 until distance c1, with most short distance until the central axis T to the tunnel 7a of wire portion 7 of accelerating tube 1
Relationship from c2 simultaneously meets value as following formula.
[formula 6]
Qmax=(c2/c1)+1
In addition, the propulsive force ratio p that accelerating tube 1 applies to weft yarn is identically as yarn speed ratio q, by the overall length L of accelerating tube 1,
The length A of straight line portion 1b relative to the ratio A/L of the overall length L of accelerating tube 1, the inner surface of tapered portion 1a tilt angle theta it
Between relationship and found out.Moreover, for L, the value than A/L and θ, with more empty than according to the compression supplied to main burner 10
The pressure of gas or supplied to main burner 10 compressed air valve unlatching during target value and the minimum value pmin that determines is big
Mode determine propulsive force ratio p.Here, the inner surface of tapered portion 1a tilts and forms tilt angle theta, thus propulsive force ratio p
It is improved, so can correspondingly reduce the pressure of the compressed air supplied to main burner 10, supply and compress to main burner 10
During the unlatching of the valve of air, thus, it is possible to realize energy conservation.
And more specifically, propulsive force ratio p and yarn speed ratio q passes through deduction formula f (L, A/ for being obtained by multivariate analysis
L, θ) and found out.Moreover, the length A of straight line portion 1b is decided by push away relative to the range of the ratio A/L of the overall length L of accelerating tube 1
Into the range that power ratio p is bigger than minimum value pmin and yarn speed ratio q is smaller than maximum value qmax.Specifically compare A/L as what is determined in this way
Range an example, when θ=0.1, L=240mm, qmax=1.15, pmin=1.2, the length A of straight line portion 1b relative to
The range of the ratio A/L of the overall length L of accelerating tube 1 is 0.13 < ratio A/L≤0.76.
In this way by suitably determining the range of the length A of the straight line portion 1b of accelerating tube 1, thus, it is possible to prevent because of weft yarn
The generation of latitude knot caused by front end tampers, and main burner 10 is able to maintain that high weft yarn conveying capacity
In addition, accelerating tube 1 also may be integrally formed with sleeve 4.Thereby, it is possible to reduce the components number of air-jet loom 100.
Also, for the straight line portion 1b of accelerating tube 1, the second accelerating tube of rectilinear form can also be connected via joint component.As a result,
The overall length L of accelerating tube can be made elongated, weft yarn conveying capacity can be further increased.
