Controller 43 counts the quantity of the detection signal of air ring that each self-indication of transmitting from detector 10 is become by weft yarn Y shape, and signal transmission to pin 8 in order to engage with weft yarn Y when the count number of air ring reaches predetermined value.The time when quantity of air ring reaches predetermined value is detected by encoder (not shown) with regard to the angle position of air-jet loom 1, and the angle position detected at that time was stored in controller 43 as the weft yarn release deadline.In response to the detection signal leading the arrival of end of instruction weft yarn Y carrying out self-detector 11, controller 43 determines whether any fault that there occurs weft yarn insertion, and the angle position of the air-jet loom 1 detected at that time by encoder is stored as the weft yarn insertion deadline.
Controller 43 records and stores multiple database 65,66,67 as shown in Figure 2 wherein, and wherein the data of best auxiliary jet pressure are for the dissimilar data being associated to loom speed of dent.Database 65,66,67 makes for three groups of different fabric conditions and weaving condition.As illustrated that with the form of line chart as shown in Fig. 2 of database 65, transverse axis represents loom speed, and the longitudinal axis represents best auxiliary jet pressure.In the figure, line 60,61,62 shows the relation of dent 58 between best auxiliary jet pressure and loom speed for three kinds of dissimilar T1, T2, T3.Although the line chart of Fig. 2 for the sake of simplicity property to merely illustrate three kinds of dent 58 dissimilar, the dent 58 of four kinds or more types can be there is in actual line chart.Below how description is prepared the database shown in Fig. 2.
In the present embodiment, under particular web condition and weaving condition, carry out weaving operation in advance, and based on during above weaving operation from detector 10,11, the data that obtain of principal pressure meter 19 and secondary stress meter 32 prepare the line chart of relation that weft yarn as shown in Figure 3 inserts deadline, angle difference and auxiliary jet pressure.In the line chart of Fig. 3, transverse axis represents auxiliary jet pressure or the air sparging pressure of auxiliary jet 3, the left-hand side longitudinal axis represents weft yarn and inserts the deadline, and right-hand side longitudinal axis representative instruction weft yarn insertion deadline and weft yarn discharge the angle difference of the difference between the deadline.In the line chart of Fig. 3, line 63 and line 64 is depicted based on the data that obtain during being changed to make weft yarn to insert the weaving operation of deadline stabilisation at auxiliary jet pressure, described line 63 indicates the weft yarn along with the change of auxiliary jet pressure to insert the change of deadline, and described line 64 indicates the change of the angle difference of the change along with auxiliary jet pressure.
As from the line 63 in Fig. 3,64 known, no matter auxiliary jet pressure how, and it is all constant that weft yarn inserts the deadline.Need to be maintained in given range this is because weft yarn inserts the deadline, insert for stable weft yarn.On the other hand, when the pressure P of auxiliary jet pressure higher than an X place, angle difference is constant, but is lowered with the pressure P of auxiliary jet pressure from an X, and angle difference increases gradually.
The factor of this increase of angle difference is as follows.When auxiliary jet pressure is low, the flight of weft yarn Y is by less assistance, and this change causing weft yarn to insert the deadline such as postpones.In order to the weft yarn preventing from causing unstable weft yarn to insert inserts this change of deadline, the pressure of the air injected from main burner 5 or series nozzle 6 is increased, to increase weft yarn insertion speed, thus it is constant to keep weft yarn to insert the deadline.The air sparging pressure increasing main burner 5 or series nozzle 6 makes weft yarn discharge deadline acceleration, increases angle difference thus, and namely constant weft yarn insertion deadline and weft yarn discharge the difference between the deadline.The excessive increase of the weft yarn insertion speed caused by main burner 5 or series nozzle 6 can cause the unstable flight of weft yarn Y.
Therefore, in weaving operation, any given fabric condition of the line chart of Fig. 3 and the auxiliary jet pressure of weaving condition can be obtained as being suitable under it, preferably should come the pressure P at selected element X place or higher pressure based on the line 64 of Fig. 3 of the change of instruction angle difference.But in view of energy saving, excessive auxiliary jet pressure is disadvantageous, because the line 64 of the change of instruction angle difference is constant when the pressure P of auxiliary jet pressure higher than an X place.In the present embodiment, the pressure P at some X place is selected as best auxiliary jet pressure, and it causes constant weft yarn to insert the stabilized flight of deadline and weft yarn Y, and allows auxiliary jet to less consumption of air, and this contributes to energy saving.
In the line chart of Fig. 3, the line 64 of the change of instruction angle difference obtains via the weaving operation under given fabric condition and weaving condition.The present inventor is found by many experiments: according to the type of the dent 58 of the part as weaving condition and the loom speed of air-jet loom 1, best auxiliary jet pressure P can change significantly.The type of dent 58 can be counted by transverse tooth thickness degree, tooth, space ratio is specified.In the present embodiment, transverse tooth thickness degree is used to the type of specifying dent 58, and is indicated on (see Fig. 5) on the screen 57 of display 56 as the project of weaving condition.
Except using the dent 58 of number of different types to carry out weaving operation with multiple different loom speed under the external identical fabric condition of the type of loom speed and dent 58 and weaving condition, and the dent 58 of every type is prepared to multiple line charts of the line chart being similar to Fig. 3 by different loom speeds.Then, by the data of the best auxiliary jet pressure P at the some X place on the line 64 of dissimilar 58 and different loom speeds extraction in corresponding line chart of dent.This data of the best auxiliary jet pressure P obtained from line 64 are associated to the data of loom speed by type such as T1, T2, T3 of dent 58, make database 65 as shown in Figure 2 and the similar database 66,67 that indicated by double dot dash line is produced.Database 65,66,67 is recorded and is stored in controller 43.Database 65,66,67 not only can be stored with the form of line chart, but also can be stored with the form of the mathematical formulae made based on this line chart.
