Description
Technical field
The present invention relates in the air injection type loom to set between the injection period of auxiliary jet the method for (injection beginning time-injection concluding time).
Background technology
In the air injection type loom, along many auxiliary jets of wefting insertion path configurations, it carries out wefting insertion through during predefined, carrying out aerojet to the weft yarn that penetrates from main burner.Usually, said many auxiliary jets constitute: put in order by it, a plurality ofly be divided into one group, each auxiliary jet in belonging to same group is connected with shared switch valve, side by side sprays.Such group is called " auxiliary jet group " in the present invention.And as shown in Figure 6, with when the wefting insertion, each auxiliary jet group begins to set between injection period by the mode of the property the taken over injection that puts in order from supplying the yarn side.
Yet, generally when setting between the injection period of above-mentioned each auxiliary jet group only consider from the angle of wefting insertion stability, so, might not be to be set in required Min., also can there be the superfluous situation of setting sometimes.That is if only consider from the angle of wefting insertion stability, as long as make that long enough is just passable during the aerojet of each auxiliary jet group, but this will cause the aerojet amount to increase, and therefore be unfavorable for energy-conservation (cutting down the aerojet amount).
So patent documentation 1 discloses a kind of establishing method, it related between the injection period of auxiliary jet, and purpose is to realize simultaneously the reduction of the stability and the aerojet amount of wefting insertion.Below, the establishing method of patent documentation 1 is done simple declaration.
At first, for each auxiliary jet group by between predefined injection period, carry out the change of advanced injection concluding time, make and only to cut down the predefined small time between the injection period of leaning on the anti-auxiliary jet group that supplies the yarn side most.Then, under this state, try wefting insertion and detect time of advent of weft yarn,, then also carry out same change between injection period for an auxiliary jet group of the upstream side of wefting insertion direction if its detected value is below the desired value.On the contrary, if detected value exceeds desired value, then said change is returned to original state, end setup.Even said change proceeds to by supplying the auxiliary jet group of yarn side, but detected value is when still be desired value following, and the auxiliary jet group of confession yarn side begins from leaning on most instead once more, carries out above-mentioned change by putting in order.Like this, begin to spray the concluding time by the change that puts in order from leaning on most the anti-auxiliary jet group of yarn side that supplies, be in the state below the object time in the time of advent, promptly wefting insertion just can be realized subduing of aerojet amount by in the scope of the state of stably carrying out.
The prior art document
Patent documentation
Patent documentation 1: japanese kokai publication hei 5-86542 communique
Can find out that from the establishing method of above-mentioned patent documentation 1 its technological thought only is: begin from leaning on most the anti-auxiliary jet group of yarn side that supplies, by putting in order the advanced injection concluding time.In this case, begin number from leaning on most the anti-yarn side that supplies, the reduction that is positioned at the aerojet amount of second group of each later auxiliary jet group is equal to or less than the reduction of the aerojet amount of the auxiliary jet group that is positioned at its wefting insertion direction downstream.
Yet, such establishing method realize aspect the subduing of aerojet amount not talkative very abundant.Below, be elaborated.
Be located in the auxiliary jet group of anti-confession yarn side, their injection not only has the effect of transporting weft yarn, also have to final with specific length by near the application of force weft yarn leading section of wefting insertion, and in the effect of front weft traction.Therefore, it is limited cutting down between the injection period relevant with its aerojet amount, if reduction excessively, then weft yarn took place earlier to relax before being interweaved by warp thread, caused producing in the fabric fault.
On the other hand, be located in the auxiliary jet group of wefting insertion direction medial side, compare with the auxiliary jet group of anti-confession yarn side, it is less to cut down between its injection period the influence that wefting insertion (time of advent, weft yarn lax etc.) is caused, and therefore, can cut down between injection period biglyyer.
But; In the establishing method of said patent documentation 1; If do not cut down between the injection period that just can not cut down between the injection period of auxiliary jet group of anti-confession yarn side near the auxiliary jet group of confession yarn side, so can not make reduction between the injection period of the auxiliary jet group that is positioned at wefting insertion direction medial side greater than the reduction between the injection period of the auxiliary jet group that is positioned at anti-confession yarn side.Therefore, can not cut down the aerojet amount fully.
Summary of the invention

Fig. 2 representes to be presented at a routine displaying contents of setting in display 47 display frames.In example shown in Figure 2, display frame has shown following displaying contents with a picture: can carry out between the injection period of each auxiliary jet group the change of (injection beginning time-injection concluding time) to each wefting insertion series.
In this displaying contents, the half side bar chart that has shown between the injection period of representing each auxiliary jet group in a left side.In the figure, the scale on the transverse axis is represented degree in crank angle (the loom main shaft anglec of rotation), and the scale on the longitudinal axis representes for the yarn side to be the fabric width of reference position.With the longitudinal axis on the corresponding position of fabric width, 13 auxiliary jet groups representing present embodiment with the length of bar shaped are between injection period separately.For each auxiliary jet group, by supply the yarn side be expressed as 1G, by its next door that puts in order be expressed as 2G, again the next door be expressed as 3G, by that analogy.The straight line of oblique crosscut has generally been represented the flight condition of weft yarn in the bar chart.In illustrated example, the wefting insertion time started is 90 ° of degree in crank angles, and target is established 230 ° of degree in crank angles the time of advent.
In illustrated example, be provided with 6 kinds of aerojet amounts and cut down pattern, various patterns can be selected arbitrarily.Button through the vertical row in bar chart right side show is selected various patterns.Each button is executed the hachure that can be different from other buttons in its square interior, and, inner at hachure with the numbering corresponding with various patterns.In this picture, selection be and with numbering 6 the corresponding pattern of button.On button next door with numbering 2-6, show the literal and the small-sized square of "+pattern ", said small-sized foursquare inside has the numbering than the numbering only little 1 of each button.This is that sense of vision ground has for example been represented, if number 2 pattern, has comprised that exactly the aerojet amount of 1 the pattern of numbering is cut down pattern.
In illustrated example, can cut down pattern to each wefting insertion series setting air emitted dose.In this case, the another kind of button that shows through the vertical row of picture right-hand member is selected wefting insertion series.This another kind button has been executed confession yarn body tag in its square interior, and, supplying yarn body tag inside to have and the corresponding numbering of each wefting insertion series.In this picture, shown the button that supplies the yarn body tag of executing that is numbered 1-8, supply the button of yarn body tag to select but wherein be numbered executing of 1-6.It is brighter that the button that can select is shown as brightness, if after it is selected, it is darker then to be shown as brightness.In this picture, selection be and with the corresponding wefting insertion series of numbering 1 button.On the other hand, be numbered 7,8 execute supply the yarn body tag button to be shown as brightness lighter, cannot select with expression.
In the present embodiment; According to the predefined weaving condition of main control unit 42a (for example; Loom rotation number, fabric width, weft yarn kind etc.); Can calculate the initial set value of each auxiliary jet group between injection period automatically, with respect to these initial set value, each pattern shown in Figure 2 is that the aerojet amount of independent (can not make up) is cut down the pattern that pattern is revised.
Fig. 3 has explained the initial set value of each auxiliary jet group between injection period shown in Figure 2 with bar chart, and the aerojet amount is cut down pattern.In addition; For the relation that makes initial set value and the aerojet amount of each auxiliary jet group between injection period cut down pattern is convenient to understand; Fig. 3 will with Fig. 2 in cooperate corresponding horizontal stripe between the injection period of each auxiliary jet group of the degree in crank angle record on the transverse axis, depict with the form of its right-hand member (spraying the concluding time) alignment.
At first, the initial set value of auxiliary jet group between injection period carried out detailed explanation.In illustrated example, be presented at the left side the vertical row of the rectangle horizontal stripe of the initial set value of each auxiliary jet group of aforesaid expression between injection period.The horizontal stripe of each auxiliary jet group is shown as: when right-hand justified becomes vertical one to be listed as, in turn upwards pile up towards anti-confession yarn side from supplying the yarn side.The left end and the right-hand member of the horizontal stripe after these are piled up are represented the injection beginning time of each auxiliary jet group between injection period and the initial set value of spraying the concluding time with degree in crank angle respectively.The degree in crank angle of said injection beginning time and injection concluding time little by little increases by putting in order towards anti-confession yarn side from supplying the yarn side.Between injection period by the said injection beginning time with spray the concluding time and confirm, lean on most anti-supply the yarn side for the longest, lean on most supply the yarn side for the shortest, in addition be to equal or be longer than between the injection period of a last confession yarn side of self.The area of horizontal stripe is equivalent to the aerojet amount.
Setting between injection period is not that each auxiliary jet group is carried out, but each auxiliary jet cohort is carried out, and said auxiliary jet cohort is by constituting by the adjacent each other auxiliary jet group more than 2 that puts in order.Said among the present invention " the auxiliary jet cohort in downstream " is meant, leans on anti-2 groups that above auxiliary jet group constitutes that supply the auxiliary jet group of yarn side most by comprising.Said among the present invention " the auxiliary jet cohort of upstream side " be meant, by 2 groups that above auxiliary jet group constitutes that comprise by the auxiliary jet group that supplies the yarn side.Said among the present invention " the auxiliary jet cohort of middle reaches side " be meant, the group more than 1 that is made up of the auxiliary jet group beyond the included auxiliary jet group of each auxiliary jet cohort in upstream side and downstream.
On this basis; In the illustrated example; From leaning on most the anti-auxiliary jet group 13G of yarn side that supplies to begin towards supplying the yarn side; Auxiliary jet cohort GU1 by 3 the auxiliary jet group 13G-11G formation downstreams that put in order from beginning towards anti-confession yarn side by the auxiliary jet group 1G that supplies the yarn side, constitutes the auxiliary jet cohort GU3 of upstream sides by 4 the auxiliary jet group 1G-4G that put in order.Except the auxiliary jet cohort in these upstream sides and downstream, remaining auxiliary jet group 5G-10G constitutes the auxiliary jet cohort GU2 of a middle reaches side.In illustrated example, these 3 auxiliary jet cohort GU1-GU3 as object, are stipulated aerojet amount reduction pattern.

The Board Lot of independent numeral reduction of record in the above-mentioned table 1, it is equivalent to " the reduction pattern between the injection period that each auxiliary jet cohort is individually stipulated " of the present invention.From each auxiliary jet cohort in the upstream side of this table 1, middle reaches side, downstream, though the situation identical with other mode contents arranged, as a whole, different with the content of other pattern.
Above-mentioned pattern 1-4 belongs to said among the present invention " the 1st reduction pattern ".The 1st reduction pattern is meant, cuts down at least between the injection period of auxiliary jet cohort of upstream side, and, the identical pattern of reduction between the injection period between the injection period in the auxiliary jet cohort of middle reaches side in the auxiliary jet cohort of reduction and upstream side.And pattern 1-4 is said among the present invention " the 1st reduction pattern comprises that reduction is identical between the injection period of auxiliary jet cohort of upstream side and middle reaches side, and the whole different a plurality of reduction patterns of reduction ".
On the other hand, pattern 5,6 belongs to said among the present invention " the 2nd reduction pattern ".The 2nd reduction pattern is meant that reduction is greater than the pattern of reduction between the injection period of other auxiliary jet cohorts between the injection period of the auxiliary jet cohort of middle reaches side.And, pattern the 5, the 6th, said among the present invention " the 2nd reduction pattern comprises the different a plurality of reduction patterns of reduction between the injection period of auxiliary jet cohort of middle reaches side ".
In above-mentioned multicolor weft insertion loom; As initial setting; Use the setting display 47 of setting display unit 46 to set weaving condition, said weaving condition comprises the wefting insertion pattern of employed weft yarn kind of rotation number, the wefting insertion of fabric width, loom and expression weft yarn selecting sequence.These weaving conditions all are stored in the memory (not shown) in the main control unit 42a of loom control device 42.
In these weaving conditions; According to the injection period of auxiliary jet between relevant condition (for example; Fabric width, rotation number, weft yarn kind etc.); The CPU50 that sets display unit 46 uses regulated procedure to calculate the initial set value between the injection period of each auxiliary jet cohort, and the initial set value that calculates is stored in the memory in the main control unit 42a.
Setting between the injection period of each auxiliary jet cohort is to carry out according to the following steps.
(1) at first, operating personnel are presented at picture shown in Figure 2 and set in the display.In addition, being shown in the half side figure in Fig. 2 left side, is as shown in Figure 6 at first, and the state of initial set value is fixedly shown by former state.
(2) then, operating personnel are through selecting any pattern, make that the injection concluding time between the injection period of each auxiliary jet cohort obtains revising.Each pattern can at random be selected by operating personnel.For example, in the wefting insertion series that will set by the weft yarn of wefting insertion, if also can carry out required wefting insertion even rule of thumb draw the reduction of the auxiliary jet group of increase (shorten between injection period) middle reaches side, can be from first with regard to preference pattern 5 or pattern 6.If do not know what to be cut down, just can select reduction little pattern 1 or pattern 2 etc. to get final product.
(3) each wefting insertion series is carried out above-mentioned correction operations (operation of the injection concluding time between the injection period of correction initial set value).Wefting insertion series to all is all revised, and at this moment, this revised setting value is sent to wefting insertion control part 44, and is stored in the memory (not shown) in the wefting insertion control part 44.
Its result; Wefting insertion control part 44 is according to the weft yarn selection signal S1 that selects signal generation 45 to send from weft yarn with between the injection period to serial each the auxiliary jet cohort set of selecteed wefting insertion; When wefting insertion, the Kai Heguan of each electromagnetic switch valve 36 that the control auxiliary jet is used.
(4) after accomplishing above-mentioned setting, operating personnel confirm through test weaving whether selected aerojet amount reduction pattern is suitable.For example; Carry out the result of wefting insertion according to above-mentioned setting; If arrived in the permissible range that is being later than target time of advent by the weft yarn of wefting insertion in certain wefting insertion series, or at this weft yarn situation such as lax take place, it is excessive then to be judged as reduction; And consider to change to according to the pattern of the little one-level of reduction to revise, reset between injection period.
If weft yarn arrives in the target permissible range of the time of advent; And when setting between injection period through the little pattern correction of employing reduction; In order to confirm further to cut down the aerojet amount; Can consider that the pattern that changes to according to the big one-level of reduction revises, reset between injection period.
(5) repeat the operation that above-mentioned setting → test weaving → change is revised, its result can be with respect to the initial set value between the injection period of auxiliary jet group in each wefting insertion series, and the reduction of aerojet amount is set at suitable value.
