Controller 43 is counted the quantity of the detection signal of the air ring that each self-indication of transmitting from detector 10 becomes by weft yarn Y shape, and signal transmission to pin 8 in order to engage with weft yarn Y in the time that 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 detecting was at that time stored in controller 43 as the weft yarn release deadline.In response to the detection signal of the arrival that leads end of indication weft yarn Y that carrys out self-detector 11, controller 43 has determined whether to occur any fault that weft yarn inserts, and the angle position of the air-jet loom being detected at that time by encoder 1 is stored as to the weft yarn insertion deadline.
Controller 43 records and stores multiple databases 65,66,67 as shown in Figure 2 therein, and wherein the data of best auxiliary jet pressure are for the dissimilar data that are associated to loom speed of dent.Database the 65,66, the 67th, 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 dent 58 for three kinds of dissimilar T1, T2, the T3 relation between best auxiliary jet pressure and loom speed.Although the line chart of Fig. 2 for the sake of simplicity property only to show three kinds of dent 58 dissimilar, in actual line chart, can there is the dent 58 of four kinds or more kinds of types.How to prepare the database shown in Fig. 2 by describing below.
In the present embodiment, under particular web condition and weaving condition, weave in advance operation, and based on weaving above data that operating period obtains from detector 10,11, principal pressure meter 19 and secondary stress meter 32 and prepare weft yarn as shown in Figure 3 and insert the line chart of the relation of 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 that weft yarn inserts the deadline, and right-hand side longitudinal axis representative indication weft yarn inserts the angle difference of the difference between deadline and weft yarn release deadline.In the line chart of Fig. 3, so that inserting the data of weaving operating period acquisition of deadline stabilisation, weft yarn draws line 63 and line 64 based on being changed at auxiliary jet pressure, described line 63 is indicated the variation of inserting the deadline along with the weft yarn of the change of auxiliary jet pressure, and described line 64 is indicated the variation along with the angle difference of the change of auxiliary jet pressure.
As known in the line 63,64 from Fig. 3, no matter auxiliary jet pressure how, it is all constant that weft yarn inserts the deadline.This is because weft yarn inserts the deadline need to be maintained in given range, inserts for stable weft yarn.On the other hand, when auxiliary jet pressure is during higher than the pressure P at an X place, angle difference is constant, but is lowered from the pressure P of an X with auxiliary jet pressure, and angle difference increases gradually.
The factor of this increase of angle difference is as follows.In the time that auxiliary jet pressure is low, the flight of weft yarn Y is by less assistance, and this causes the variation of weft yarn insertion deadline such as delay.In order to prevent from causing weft yarn that unstable weft yarn inserts to insert this variation of deadline, the pressure of the air of injecting from main burner 5 or series nozzle 6 is increased, to increase weft yarn insertion speed, thereby it is constant to keep weft yarn to insert the deadline.The air sparging pressure that increases main burner 5 or series nozzle 6 makes weft yarn discharge deadline acceleration, increases thus angle difference, and constant weft yarn inserts the difference between deadline and weft yarn release deadline.The excessive increase of the weft yarn insertion speed causing by main burner 5 or series nozzle 6 can cause the unstable flight of weft yarn Y.
Therefore, as being suitable for weaving in operation at any given fabric condition of its lower line chart that can obtain Fig. 3 and the auxiliary jet pressure of weaving condition, preferably the line 64 of Fig. 3 of the change based on indication angle difference comes the pressure P at selected element X place or higher pressure.But in view of energy saving, excessive auxiliary jet pressure is disadvantageous, because the line 64 of the change of indication angle difference is constant at auxiliary jet pressure during higher than the pressure P at an X place.In the present embodiment, the pressure P at some X place is selected as best auxiliary jet pressure, the stabilized flight that it causes constant weft yarn to insert deadline and weft yarn Y, and allow the still less consumption of auxiliary jet to air, this contributes to energy saving.
In the line chart of Fig. 3, the line 64 of the change of indication angle difference is to obtain via the operation of weaving under given fabric condition and weaving condition.The present inventor is found by many experiments: according to the loom speed of the type of the dent 58 of the part as weaving condition and air-jet loom 1, best auxiliary jet pressure P can change significantly.The type of dent 58 can recently be specified by transverse tooth thickness degree, tooth counting, space.In the present embodiment, transverse tooth thickness degree is used to specify the type of dent 58, and is indicated on as the project of weaving condition on the screen 57 of display 56 (seeing Fig. 5).
Except the type of loom speed and dent 58, under identical fabric condition and weaving condition, also weave operation with the dent 58 of number of different types with multiple different loom speed, and prepare multiple line charts of the line chart that is similar to Fig. 3 for the dent 58 of every type by different loom speeds.Then, extract the data of the best auxiliary jet pressure P at the some X place on the line 64 in corresponding line chart out by dissimilar 58 and different loom speeds of dent.The type of this data of the best auxiliary jet pressure P obtaining from line 64 by dent 58 be such as T1, T2, T3 are associated to the data of loom speed, makes database 65 as shown in Figure 2 and the similar database 66,67 of being 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.
In the description of the present embodiment, for simplicity, in Fig. 2, only show three kinds of databases 65,66,67 of preparing for three kinds of different fabric conditions and weaving condition.In fact, four kinds or more kinds of different database are produced and are stored in controller 43.Prepare multiple databases such as 65,66,67 permissions are easily selected best auxiliary jet pressure for the fabric of any type.
