In order optimally to select air consumption to have the pressure of the sub-nozzle of considerable influence, the jet type loom 1 of the present embodiment is configured so that the screen 62 of display 61 shows curve Figure 63, this curve Figure 63 represents the main burner pressure for each different pre-stator nozzle exit pressure, as shown in Figure 2.The pressure of curve Figure 63 based on the main burner 7 in the time that the angular position of setting in advance completes wefting insertion carry out textile operation with multiple main burner pressure under fixing sub-nozzle exit pressure during and being made.More specifically, wefting insertion uses different main burner pressure to carry out repeatedly in the situation that sub-nozzle exit pressure is set in predetermined value, and the expected angle position that is chosen in prior setting completes the main burner pressure at wefting insertion place.For each different pre-stator nozzle exit pressure, such wefting insertion is repeatedly carried out repeatedly, and the main burner pressure of selecting for each different pre-stator nozzle exit pressure is plotted on curve Figure 63.
When under the fabric concrete and weaving condition in jet type loom 1 when Woven fabric, during textile operation, the pressure of main burner 7 and sub-nozzle 5 is measured by principal pressure measuring instrument 23 and sub-pressure-measuring device 36 respectively, and the data of such pressure are stored in controller 47.Textile operation is performed under each different pre-stator nozzle exit pressure, and is performed under each main burner pressure for each so different pre-stator nozzle exit pressure.
In controller 47, have program, the pressure data of this program storage main burner 7 at this pressure place, for each different pre-stator nozzle exit pressure, completes wefting insertion on the angle position of the prior setting of jet type loom 1.Controller 47 also has the program of forming curves Figure 63, and curve Figure 63 represents main burner 7 pressure for each different predetermined pressure of sub-nozzle 5, and then makes the screen 62 of display 61 show this curve Figure 63.
In order to set optimum sub-nozzle exit pressure, the operator of loom makes the screen 62 of display 61 show the curve Figure 63 shown in Fig. 2, and this curve Figure 63 represents main burner 7 pressure for each different predetermined pressure of sub-nozzle 5.Showing in Fig. 2 of curve Figure 63, trunnion axis represents sub-nozzle exit pressure or the pressure of the air that sprays from sub-nozzle 5, and vertical axes represents main burner pressure or the pressure of the air that sprays from main burner 7.Higher main burner pressure and sub-nozzle exit pressure cause the air consumption of rising and the energy consumption of rising, and lower main burner pressure and sub-nozzle exit pressure cause the air consumption of minimizing and the energy saving of raising.
According to curve Figure 63, main burner pressure therein sub-nozzle exit pressure higher than constant in a scope for the pressure P at X place (such scope is hereinafter referred to high pressure range A) ground in lower level, but rising gradually in the scope (such scope is hereinafter referred to as low-pressure scope B) reducing from the pressure P of an X at sub-nozzle exit pressure.In the high pressure range A that sub-nozzle exit pressure is higher therein, contribute to preferably the flight of weft yarn Y, even and if therefore when main burner pressure decreased, wefting insertion also completes in the angular position of setting in advance.On the other hand, in the low-pressure scope B that sub-nozzle exit pressure is lower therein, not too contribute to the flight of weft yarn Y, this can cause wefting insertion to complete the delay of angle position.In this case, main burner pressure need to be raised, to compensate the less auxiliary of the flight of sub-nozzle 5 to weft yarn Y.
In high pressure range A, even if when group nozzle exit pressure reduces to reduce air consumption as far as possible, wefting insertion also completes and the main burner pressure that do not raise in the angular position of setting in advance.But, in the time that main burner pressure raises in pressure limit B, the pressure that is used for the main burner 7 of the wefting insertion of weft yarn Y becomes too strong with respect to the pressure of sub-nozzle 5, and can not contribute to the weft yarn Y flight of institute's wefting insertion, and this can cause the irregular flight of weft yarn Y and therefore cause unsettled wefting insertion.
When with reference to curve Figure 63, the operator of loom can guarantee that the sub-nozzle exit pressure P at an X place should be chosen as the air consumption for minimum beggar's nozzle 5, and during keeping stable wefting insertion simultaneously and being stabilized in textile operation, wefting insertion completes residing angle position.For the purpose of safe, can understand, should be preferably optimum sub-nozzle exit pressure by the pressure selection a little more than P.The sub-nozzle exit pressure of the wefting insertion that therefore, the display unit of the present embodiment allows to select suitably to provide stable and the air consumption of minimizing.
Fig. 3 shows the second embodiment according to display unit of the present invention.In the drawings, identical Reference numeral is for shared element or the member of the first and second embodiment, and will omit such element to the second embodiment or the description of member.In a second embodiment, controller 47 has program therein, the data of the pressure of this program storage main burner 7 are (at this pressure place, for each different pre-stator nozzle exit pressure, complete wefting insertion in the angular position of the prior setting of jet type loom 1) and complete the data of the angle position of wefting insertion at this main burner pressure place.Controller 47 also has following program: this program forms the curve map of the angle position when representing for curve Figure 63 of each different main burner pressure of stator nozzle exit pressures in advance and also completing wefting insertion by the expression of 65 signs for each different pre-stator nozzle exit pressures, and then makes the screen 64 of display 61 show this curve Figure 63,65.
In order to set optimum sub-nozzle exit pressure, the operator of loom can make screen 64 show the curve Figure 63,65 shown in Fig. 3.Showing in curve Figure 63, Fig. 3 of 65, trunnion axis represents sub-nozzle exit pressure or the pressure of the air that sprays from sub-nozzle 5, angle position when left-hand side vertical axes represents that wefting insertion completes, and right-hand side vertical axes represents main burner pressure or the pressure of the air that sprays from main burner 7.
The curve Figure 63 that completes curve Figure 65 of angle position and main burner 7 pressure of each the different predetermined pressures for sub-nozzle 5 for the wefting insertion of each different predetermined pressure of sub-nozzle 5 is presented on display 64 together.The display unit of the second embodiment allows loom operator to complete curve Figure 65 of angle position with reference to wefting insertion, and based on curve Figure 63 using a pressure P at X place or the pressure selection a little more than pressure P in high pressure range A as sub-nozzle exit pressure.This allows loom operator to select optimum sub-nozzle exit pressure, guarantees that wefting insertion completes angle position and is roughly stabilized in horizontal E, thereby stable wefting insertion and the air consumption of minimizing are provided from curve Figure 65 simultaneously.
Fig. 4 shows the 3rd embodiment according to display unit of the present invention.In the drawings, identical Reference numeral is for first and shared element or the member of the 3rd embodiment, and will omit such element to the 3rd embodiment or the description of member.In the 3rd embodiment, controller 47 has following program: the data of the pressure of this program storage main burner 7 are (at this pressure place, for each different pre-stator nozzle exit pressure, complete wefting insertion in the angular position of the prior setting of jet type loom 1), complete angle position and wefting insertion completes angle position and weft yarn releases the differential seat angle between angled position at the wefting insertion at this main burner pressure place.Controller 47 also has following program, this program form represent for curve Figure 63 of the main burner pressure of each different pre-stator nozzle exit pressure, for the wefting insertion of each different pre-stator nozzle exit pressure complete curve Figure 65 of angle position and by the expression of 66 signs the curve map for the above-mentioned differential seat angle of each different pre-stator nozzle exit pressure, and then make the screen 67 of display 61 show such curve Figure 63,65,66.
In order to set optimum sub-nozzle exit pressure, the operator of loom makes screen 67 show curve Figure 63,65,66 as shown in Figure 4.Showing in curve Figure 63,65, Fig. 4 of 66, trunnion axis represents sub-nozzle exit pressure or the pressure of the air that sprays from sub-nozzle 5, left-hand side vertical axes represents that wefting insertion completes residing angle position, and right-hand side vertical axes represents main burner pressure or the pressure of the air that sprays from main burner 7.Right-hand side vertical axes also represents that wefting insertion completes angle position and weft yarn releases the differential seat angle between angled position.Be presented at together on display 67 for curve Figure 66 of the differential seat angle of each different predetermined pressures of sub-nozzle 5 and curve Figure 63 of main burner 7 pressure and for curve Figure 65 that the wefting insertion of each different predetermined pressures of sub-nozzle 5 completes angle position.
As clearly visible from curve Figure 66, differential seat angle therein sub-nozzle exit pressure higher than constant in a scope of the pressure P at X1 place, but along with sub-nozzle exit pressure reduces and rising gradually from the pressure P of an X1.When a factor of this rising of differential seat angle is that group nozzle exit pressure is low, the flight of weft yarn Y obtains less auxiliaryly, and this can cause wefting insertion to complete the variation of angle position, completes such as the wefting insertion postponing.In order to prevent causing the wefting insertion of unstable wefting insertion to complete this variation of angle position, the pressure of the air spraying from main burner 7 or series nozzle 8 is raised, to improve filling insertion rate, and therefore wefting insertion is completed to angle position and is stabilized in horizontal E.
The air injection pressure that improves main burner 7 or series nozzle 8 can accelerate weft yarn and discharge, thus increase differential seat angle, and described differential seat angle is that constant wefting insertion completes angle position and weft yarn and releases poor between angled position.The speed that is excessively improved wefting insertion by main burner 7 or series nozzle 8 may cause the unsettled flight of weft yarn Y, and causes unsettled wefting insertion.
As shown in Figure 4, main burner pressure and differential seat angle start respectively to reduce and the some X and the X1 that increase place clearly presents in curve Figure 63 and 66 along with sub-nozzle exit pressure therein, and the sub-nozzle exit pressure at some X, X1 place is P.Therefore, can understand from curve Figure 63 and 66, should be the pressure that makes to provide optimum sub-nozzle exit pressure P by the compressed-air actuated pressure that is supplied to sub-nozzle 5.
If be not clear that an X in curve Figure 63 of main burner pressure, the pressure P at the some X1 place in curve Figure 66 may be selected to be optimum sub-nozzle exit pressure.If be not clear that an X1 in curve Figure 66 of differential seat angle, the pressure P at the some X place in curve Figure 63 may be selected to be optimum sub-nozzle exit pressure.In the display unit of the present embodiment, in the time selecting the sub-nozzle exit pressure of optimum of the air consumption that stable wefting insertion and minimizing are provided, the curve Figure 63 and 66 being presented at together on display 61 is relation complimentary to one another.
The display unit of the present embodiment allow loom operator in the curve Figure 65 that completes angle position with reference to wefting insertion based on curve Figure 63,66 using the pressure P at an X, X1 place or the pressure selection a little more than pressure P in high pressure range A as sub-nozzle exit pressure.This allows loom operator to select optimum sub-nozzle exit pressure, checks that wefting insertion completes angle position and be roughly stabilized in the level of the E in curve Figure 65 simultaneously.
