Description
Technical field
The present invention relates to method for information display and information display device for a kind of loom, the associated member of weaving that makes to equip on loom follows the anglec of rotation (so-called degree in crank angle) of the variation of weaving and producing and main shaft relevant and as curve, be shown in the display frame of display.
Background technology
About the associated member of weaving of equipping on loom, particularly this tension force on warp thread of shredding roller on the tension force of warp thread and the heald frame on shedding motion or warp thread carrying device brings the associated member of weaving of impact, followed the variation (displacement) of weaving and producing as curve, to be shown in the display frame of display relatively with degree in crank angle, as this prior art, had various technology.For example in patent documentation 1, disclose and will make to be shown in as the displacement curve (open curve) relevant with degree in crank angle of weaving the heald frame of associated member the technology of display frame (display part).In addition, in patent documentation 2, disclose following technology, will be as the tension force of warp thread of weaving associated member with the degree in crank angle sampling of each regulation, the tension variation of the warp thread in weaving is shown as curve (squiggle) usining on the diagram region that transverse axis is degree in crank angle.
But in loom, the specific position of sometimes knitting in width direction at it in woven weaving cotton cloth can produce through willow.And, think that like this on weaving cotton cloth, producing through willow is on the warp thread of this specific position in width direction, to produce fluffing and cause owing to knitting.In addition,, about fluffing, as one of its reason, can exemplify the unsuitable situation of relation of picking and harness motion.Specifically, in the process of picking, sometimes the front end of weft yarn by time the opening amount of Warp opening inappropriate, even or sometimes the opening amount of Warp opening from also producing fluffing because of the relation of the tension force of the warp thread with now as admissible opening amount.And in the situation that find that the woven so specific position of knitting in width direction of weaving cotton cloth produces through willow, the state producing through willow in order to eliminate this, need to carry out to this through the relevant adjustment of weaving associated member of the generation reason of willow etc.In addition, the generation reason as this through willow, for example, can consider as follows.
The situation that the loom of take is water jet loom is example, when the first head part of the injection water spraying from picking mouth for picking weft yarn is passed through Warp opening, contacts sometimes because the relation with opening amount makes injection water with warp thread, and its result produces fluffing.Specifically, relation due to the opening amount of the warp thread of the position of advancing of part ahead of injection water, the tendency that particularly exists the injection water that sprays from picking mouth to contact with warp thread in Warp opening in initial stage of picking or tailend, follow this contact, the part of the fiber of warp thread is damaged and produce fluffing.
But, about contacting of this injection water and warp thread, except the relation of the opening amount of the warp thread of the He Gai position, position of the first head part of described injection water, also relevant with the big or small pulsatile change of injection water.Specifically, well-known, the injection water spraying from picking mouth is not in Warp opening, to advance towards the anti-yarn side of sending with certain size, but in its traveling process, its size can pulsatile change due to the impact of air resistance etc.Therefore, in the process of remaining silent at the warp thread of the process of the Warp opening at picking initial stage or picking tailend, injection water and warp thread are not limited to contact for the gamut below the size of regulation in its opening amount, follow the pulsatile change of injection water size, in above-mentioned scope, injection water also can local contact with warp thread.
In addition, about fluffing as described above (through willow), not due to injection water, contact and will inevitably produce with warp thread, sometimes as the tension force of the warp thread of above-mentioned its time of contact also can bring impact to the generation of fluffing.That is, have tendency as follows, the tension force of warp thread is higher, follows described contact more easily to produce fluffing, in the situation that the tension force of warp thread is low, even if there is contact as described above, is also difficult to produce fluffing.
In addition, well-known, because weaving the impact of the action etc. of associated member, the tension force of warp thread can change in 1 weave cycle of loom.For example, at heald frame, for forming Warp opening, make in the warp thread process that direction moves up and down, it is the tendency rising in the maximum moment that the tension force of warp thread exists towards opening quantitative change.But, in general loom, possess for suppressing the fibre-opening unit having of the tension change of 1 weave cycle, utilize the tension force that is used for relaxing the warp thread rising of this fibre-opening unit having, and the tension force after suppressing rises.And, in the opening amount of warp thread, become after maximum, at heald frame, be to make warp thread again come the position of remaining silent to make in process that warp thread moves, the tension force of warp thread reduces gradually.Like this, in 1 weave cycle, warp tension changes, and the tension force of the warp thread in the moment contacting with warp thread at described injection water is high in the situation that the degree that on warp thread, generation is fluffed follows this contact to produce fluffing, produces described through willow.
And, In view of the foregoing, the specific position of knitting in width direction of weaving cotton cloth in the situation that woven has produced through willow, particularly in the situation of passing through the corresponding position of knitting width direction, position of described specific position for the first head part of the injection water with picking initial stage or tailend, operator attempts specific its reason, for this reason, at present, the curve of the tension variation of disclosed relevant warp thread in the curve of disclosed open curve in described patent documentation 1 or patent documentation 2 is shown in the display frame of display device, and according to the generation reason of the next specific fluffing (through willow) of these curves, carry out the adjustment of weaving associated member etc. relevant to this reason.
Particularly, as the result of confirming the curve of described open curve, in the situation that think that reason is due to the opening amount of the warp thread of picking initial stage and picking tailend, adjust shedding motion, change the motion of heald frame etc.In addition, not thinking that reason is only due to opening amount in the situation that, confirm the curve relevant to the tension variation of described warp thread, and, in the situation that consider that the tension state of warp thread has produced impact, carry out the tension variation of warp thread to bring the adjustment of the shedding motion of impact and fibre-opening unit having etc.
But, during in patent documentation 1 and patent documentation 2, the disclosed relevant curve of weaving the action of associated member shows, can not easily grasp the opening amount of warp thread in the moment producing through willow and the tension force of warp thread, in other words can not easily grasp the first head part of injection water by the opening amount of the warp thread in the moment (degree in crank angle) of the generation position through willow and the tension force of warp thread, have the problem specific bothersome and consuming time of described generation reason.Details as Follows.
About the woven upper generation of weaving cotton cloth through willow, owing to occurring on the surface of weaving cotton cloth, so it produces position apart from sending the distance of knitting end of yarn side easily to obtain.But, be assumed to be in the situation that the first head part of the injection water described in this position has produced and contacted with warp thread, even if observe woven weaving cotton cloth, can not obtain the degree in crank angle of this time of contact.On the other hand, in existing described curve shows, as disclosed in patent documentation 1,2, transverse axis is degree in crank angle.That is, this transverse axis is not corresponding with the position on fabric, and corresponding with the process of time in weaving process.
Therefore, at present, in the situation that found that the specific position of knitting in width direction of weaving cotton cloth produces through willow, when specific its reason, first by calculating, wait the first head part of asking for injection water to produce the moment degree in crank angle of position by it, the degree in crank angle of obtaining based on this afterwards for example shows to confirm the opening amount of warp thread according to the curve of the open curve of disclosed heald frame in patent documentation 1, or according to the curve of the tension variation of disclosed warp thread in patent documentation 2, show to confirm the tension force of warp thread, because operator must pass through above-mentioned operation, therefore, operation for specific reasons needs time and labor.
Like this, at present, the operation of the specific generation reason through willow is numerous and diverse, eliminating in the adjustment operation of problem based on its reason specific, has problem consuming time and effort.

In addition, the relevant above-mentioned setting value of respectively inputting that is stored in storer 102, picking start timing Tjet as above-mentioned in the present embodiment for the first head part of the injection water that sprays from picking mouth is by sending the degree in crank angle in the moment of knitting end of yarn side, but this picking starts timing Tjet, can be also that the front end of weft yarn W is by sending the degree in crank angle in the moment of knitting end of yarn side.; in the picking of general water jet loom; because the ejaculation prior to weft yarn W starts the injection of injection water, so the first head part of injection water is by sending the degree in crank angle in the moment of knitting end and the front end of weft yarn W of yarn side also non-uniform by sending the degree in crank angle in the moment of knitting end of yarn side correctly to say.But, because the difference of these degree in crank angles is very little, in picking, can ignore, so start timing Tjet about picking, can input any that set these degree in crank angles.In addition, arrive timing Tarr as above-mentioned be that the first head part of the injection water that sprays from picking mouth is by the anti-degree in crank angle that send the moment of knitting end of yarn side, about this arrival timing Tarr, also to start timing Tjet identical with above-mentioned picking, also can input set weft yarn W front end by the anti-degree in crank angle that send the moment of knitting end of yarn side.
In addition, about picking, start timing Tjet, also can be made as from the degree in crank angle in the moment of picking mouth spray water.That is, because the front position of picking mouth is arranged on from sending the position that end leaves a little of knitting of yarn side, so although from the degree in crank angle in moment of picking mouth spray water and injection water by sending the degree in crank angle in the moment of knitting end of yarn side correctly to say and non-uniform.But, because the difference of these degree in crank angles is very little, in picking, can ignore, so start timing Tjet about picking, can input any that set these degree in crank angles.In addition, about picking, start timing Tjet, also can be made as the degree in crank angle that penetrates the moment of weft yarn W from picking mouth.
About the water jet loom 1 of above such the present embodiment in detail, the method for asking of passing through timing Tany based on angle determiner 103 is described in detail below.
First, angle determiner 103, when asking by timing Tany, deducts picking and starts timing Tjet by arriving timing Tarr, the first head part of asking injection water from send yarn side knit end advance to counter send yarn side knit end required during (crank angle).And, because this crank angle of obtaining first head part that is injection water is advanced from what send yarn side and is knitted end to the counter distance of knitting end of sending yarn side 11 the required crank angle of the distance of knitting width L that is equivalent to weave cotton cloth, so 11 the advance relation of the required crank angle of this distance of first head part that width L can obtain distance that the first head part of injection water advances and injection water of knitting of weaving cotton cloth of setting according to the crank angle of obtaining by above-mentioned subtraction and input.Therefore, angle determiner 103 based on this relation ask the first head part of injection water to advance to weave cotton cloth 11 knit above-mentioned optional position Pa in width direction from weave cotton cloth 11 send yarn side knit end to during the required degree in crank angle of the distance L a of optional position Pa.
Angle determiner 103 to input unit 101 input, set from send yarn side knit end to the distance L a of optional position Pa time, based on above-mentioned relation, ask the first head part of the injection water required crank angle of this distance L a of advancing.And, the first head part of angle determiner 103 by adding injection water in this crank angle is that picking starts timing Tjet by the degree in crank angle in 11 the moment of knitting end of sending yarn side of weaving cotton cloth, and the degree in crank angle of the first head part of asking injection water by the moment of optional position Pa is by timing Tany.It is particularly following calculating formula.
Tany=La×(Tarr-Tjet)／L+Tjet
In addition, by using the first head part of injection water to advance to be equivalent to 11 the required crank angle of the distance of knitting width L of weaving cotton cloth of above-mentioned explanation, can be picking speed in the hope of the speed of injection water.And the picking speed that also this can be obtained is shown in the display field 202b of display frame 200 as shown in Figure 3.In addition, the above-mentioned picking speed of obtaining is average picking speed eventually, correctly says also non-uniform with the picking speed of knitting the each several part in width direction.This is because in the picking of actual water jet loom, injection water is not to enter in Warp opening 6 with certain speed, but is being the fastest speed from picking mouth has just sprayed, and slows down gradually afterwards due to air resistance etc.But, even such picking speed also can become the adjustment standard (reference) of the cardinal principle that operator is provided, so preferably show.
When asking above-mentioned picking speed, the running speed that is first water jet loom 1 according to the rotational speed of main shaft 12 is asked the revolution (rps) of every 1 second of main shaft 12.For example, if the running speed of water jet loom 1 is 600rpm, the revolution (rps) of the main shaft 12 of every 1 second is 600/60=10rps.In addition, as shown in Figure 3, if the degree in crank angle that picking is started to timing Tjet is made as 100 °, the degree in crank angle that arrives timing Tarr is made as to 230 °, injection water advances, and to knit during the required degree in crank angle of width L be 230-100=130 °.In addition, if to be made as shown in Figure 3 150cm be 1.5m by 11 the width L that knits of weaving cotton cloth, injection water advances during 1.5m needs the degree in crank angle of 130 °.Therefore, according to these relations, by following calculating formula, asking the every distance of advancing for 1 second of injection water is picking speed (m/s).
The about 41.5m/s of 360 * 1.5 * 10/130=
In addition, in above-mentioned, ask the first head part of injection water to advance to be equivalent to weave cotton cloth 11 knit the distance of width L time picking speed and show this speed, but, in addition also can same as described abovely obtain that the first head part of injection water is for example advanced until the picking speed during distance L a of the optional position Pa that above-mentioned input is set, and show this speed.
Below, the effect of the loom information display device 100 in the structure of the present embodiment is described.For example, as the problem on weaving, weaving cotton cloth, 11 the specific position of knitting in width direction produces fluffing (through willow), in the situation that infer former the contacting because of injection water and warp thread 3 of the generation of this fluffing, operator confirms injection water with loom information display device 100 first head part by the demonstration in diagram region 203, by the variation of the tension force of the warp thread 3 in the moment of this specific position, judges whether the generation reason of fluffing is contacting of injection water and warp thread 3 thus.
First operator measures from sending the end of knitting of yarn side is that (distance L a) for the length width direction of knitting of above-mentioned specific position to the generation position of fluffing.Then, be the tension variation of the warp thread 3 in confirming to weave, and show that the operation of the picture shown in Fig. 3, curve show the variation of the warp tension on the input unit 101 of loom information display device 100.
Now, in loom information display device 100, the display controller 105 output screen display instruction signals from input unit 101 to display control unit 107.And, display controller 105 is when inputting above-mentioned screen display instruction signal, from warp tension detecting device 14, read the described warp tension data T of 1 weave cycle amount, meanwhile, the downside in the diagram region 203 of the warp tension data T based on reading in the display frame 200 of display 106 is described and be take the relevant curve of the warp tension of the 1 weave cycle amount that the tension force that the longitudinal axis is warp thread 3 and the transverse axis of take be degree in crank angle.
And the above-mentioned distance L a recording, operating operation button are set in the input field 201a input of operator in display frame 200.Thus, in loom information display device 100, the storer 102 output distance L a from input unit 101 to display control unit 107, and to angle determiner 103 output display command signals.
Storer 102, when being transfused to above-mentioned distance L a, is stored.In addition, angle determiner 103 is when being transfused to above-mentioned idsplay order signal, as for asking by the information of timing Tany, from storer 102 read above-mentioned distance L a (knitting end to the distance of optional position Pa from what send yarn side), picking starts timing Tjet, arrives timing Tarr and knit width L, ask by timing Tany, and the timing Tany that passes through that this is obtained exports to display controller 105.
When inputting by timing Tany from angle determiner 103, display controller 105 shows the display field 202a of the regulation in display frame 200 by timing Tany, and, based on describe the line chart corresponding with optional position Pa on diagram region 203 by timing Tany, and then start timing Tjet and arrive timing Tarr 11 the line chart of knitting end of describing to be equivalent to weave cotton cloth based on picking.Its result, become and describing on the diagram region 203 of the curve relevant to warp tension, to cross over the figure display section on top in above-mentioned diagram region 203 and the form of the curve display section of downside, describe the state of 3 bar charts (ordinate) parallel with the longitudinal axis.
Operator shows by these in display frame 200, and the first head part (front end of weft yarn W) that can easily confirm injection water is by 11 the degree in crank angle in the moment of the generation position of knitting the fluffing in width direction and the corresponding relation of the warp tension of the generation position of fluffing of weaving cotton cloth.Therefore, operator shows the warp tension in the moment of confirming that fluffing produces according to this, for adjust fluffing the locational warp thread 3 of generation tension force and use and weave associated member or comprise the adjustment operation of weaving associated apparatus that this weaves associated member, attempt to eliminate thus fluffing (through willow).And, after having carried out this adjustment operation, make water jet loom 1 work, confirm the generation situation of fluffing, and, by display frame 200, confirm the variation of the tension force of the post-job warp thread 3 of adjustment.
Like this, according to the loom information display device 100 of the present invention that represents an example by the present embodiment, operator, in the situation that the problem on weaving produces in the specific position of knitting in width direction, weaves associated member and follows and weave the variation producing under the degree in crank angle of the first head part that can easily confirm injection water by display 106 during by this specific position.And operator, as long as the information (index) based on being obtained by display 106 is weaved the adjustment operation of associated member, can significantly subdue the needed time of operation so compare existing adjustment operation.
Above, one embodiment of the invention are illustrated, but the invention is not restricted to above-described embodiment.That is,, in the present invention, representing that weaving associated member follows the curve of the variation of weaving and producing (below also referred to as " change curve ".) diagram region on describe the line chart of knitting end position that is equivalent to weave cotton cloth and with weave cotton cloth knit the corresponding line chart in optional position in width direction (below also referred to as " the position line chart of weaving cotton cloth ".), in the above-described embodiments, this change curve is made as to the curve of the variation of the tension force that represents warp thread 3, but the invention is not restricted to this, the position line chart of also can describing to weave cotton cloth on following such change curve.
(1) also above-mentioned change curve can be made as to the curve that the heald frame 5 (weaving associated member) shown in presentation graphs 4 is followed the displacement (variation) of weaving and producing.In addition, about representing the curve of the displacement of this heald frame 5, more specifically, each heald frame 5 constantly in 1 weave cycle is followed to the displacement weaving and produce, by heald frame 5, stored the opening amount of weaving the Warp opening 6 that middle knee-action forms is relevant with degree in crank angle that should each moment as opening data, and by this opening data and curves.In addition, about the above-mentioned respectively displacement (the opening amount of Warp opening 6) of the heald frame 5 in the moment, the sensor that for example can be located at Warp opening device 4 by utilization detects take the height and position of the heald frame 5 that the height and position of fell 10 is benchmark and obtains, and above-mentioned each degree in crank angle constantly detects the degree in crank angle in the moment for this.In addition, be included in heald frame 5 that same weave cycle is moved upward and the opening data of mobile heald frame 5 these two heald frames 5 downwards in opening data, poor (distance) of the height and position of the same degree in crank angle of these two heald frames 5 is opening amount.
But, about opening data, be not limited to as the above-mentioned actual height and position that detects heald frame 5, also can be based on the pattern of the predefined heald frame 5 of Warp opening device 4 is asked to opening data.For example, in the situation that Warp opening device 4 is presetted the pattern of heald frame 5 as driven the electric shedding apparatus of each heald frame by motor, the pattern of heald frame 5 that also can be based on this setting is asked opening data, is the height and position of the heald frame 5 under each degree in crank angle.In addition, Warp opening device 4 is usingd main shaft 12 (spindle motor M) as drive source, by cam mechanism and the such physical construction of crank mechanism, make heald frame 5 knee-actions, in the situation that ask the relation of the displacement of degree in crank angle and heald frame 5 by simulate or calculating etc. according to this physical construction, also can ask opening data by such simulation or calculating etc.
The display controller 105 being connected with Warp opening device 4 is read above-mentioned opening data, and, the relevant curve (open curve) of variation based on this opening data generation as the opening amount of curve and the Warp opening 61 weave cycle amount of the displacement of expression heald frame 5.And display controller 105 is described the curve of this generation on the diagram region 203 that degree in crank angle and the longitudinal axis of take are height and position at the transverse axis of take in the display frame 200 of display 106.In addition, in the example shown in Fig. 4, as the benchmark of the longitudinal axis (height and position), with transverse axis describe to be equivalent to the sleeve index contour of the height and position of fell 10.
And, in this variation, on the diagram region 203 of the curve of the variation of the opening amount of the relevant Warp opening 6 of describing like this in demonstration, describe the above-mentioned position line chart of weaving cotton cloth.Therefore,, according to this structure, operator can easily confirm the degree in crank angle in the moment that the first head part (front end of weft yarn W) of injection water is passed through and the corresponding relation of the opening amount of Warp opening 6.For example, about the fluff generation reason of (through willow) of the problem of weaving of above-described embodiment, in the situation that be estimated as, result from the contacting of injection water and warp thread 3, the first head part that shows to confirm injection water by the open curve utilizing on diagram region 203, by the opening amount of the Warp opening 6 in the moment of the generation position of fluffing, can judge whether the generation reason of fluffing is contacting of injection water and warp thread 3.And, in the situation that being judged as injection water and contacting with warp thread 3, while can confirm that curve shows, avoid contacting such adjustment of weaving associated member.
(2) in addition, about above-mentioned change curve, also can represent following curve, it shows that for adjusting the associated member of weaving of the tension force of warp thread 3 be that shredding roller 16 is followed the displacement (variation) on the fore-and-aft direction of weaving and producing.In addition, about shredding roller 16, be the parts that comprise as in the fibre-opening unit having of weaving associated apparatus (diagram is slightly), as above-mentioned, it is for suppressing the tension change of the warp thread 3 of 1 weave cycle.More specifically, on shredding roller 16, volume hangs with the warp thread 3 of sending from warp shaft 2, by this shredding roller 16, carry out oscillating motion, the path length of the warp thread 3 between rear roller 13 and fell 10 is changed, suppress the tension change that warp thread 3 follows harness motion to produce.
About representing the change curve of the displacement of this shredding roller 16, the displacement (shredding amount) of each shredding roller 16 constantly in 1 weave cycle is relevant to the degree in crank angle that is somebody's turn to do each moment as the storage of shredding data, and by this shredding data and curves is described.In addition, about the shredding amount of shredding roller 16, the going-back position (hunting range by the position of anti-fell 10 sides) of shredding roller 16 of for example take is obtained as benchmark.
In addition, about above-mentioned shredding data, for example, can consider to utilize sensor with each degree in crank angle of regulation, to detect the displacement (shredding amount) of shredding roller 16, and make its detected value relevant with the degree in crank angle that detects the moment and draw.In addition, about shredding data, be not limited to the actual like this shredding amount that detects, also can by simulate or calculating etc., ask for the relation of degree in crank angle and shredding amount according to the structure of fibre-opening unit having.; it is drive source that general fibre-opening unit having be take main shaft 12 (spindle motor M); by physical construction make shredding roller 16 forwards, backwards direction swing; in addition; because shredding amount is determined by the length of the shredding bar linking with shredding roller 16 etc. etc.; therefore, also can by simulate or calculating etc., ask for according to the physical construction of this fibre-opening unit having the relation (shredding data) of degree in crank angle and shredding amount.In addition, at fibre-opening unit having, be the structure by main shaft 12 drive by the motor special different from spindle motor M, preset in the situation of pattern of swing of shredding roller 16, the pattern of shredding roller 16 that also can be based on this setting is asked shredding data.
And, display controller 105 is read shredding data from fibre-opening unit having (diagram slightly), and, based on this shredding data, generate as the change curve (shredding curve) of variation of shredding amount of expression 1 weave cycle amount of curve that represents the displacement of shredding roller 16, and be depicted on the diagram region 203 that the transverse axis of take in the display frame 200 of display 106 is degree in crank angle.
In addition, in the example of the change curve shown in Fig. 6, the longitudinal axis of curve mean take with the transverse axis of curve the sleeve index contour described as benchmark is the axle of shredding amount of the going-back position of shredding roller 16, represent that shredding amount becomes the axle of the place ahead (positions of fell 10 sides) along with downward become position fore-and-aft direction (swaying direction) large, that be shredding roller 16 from this sleeve index contour.Particularly, be illustrated in shredding roller 16 in the situation that shredding curve declines and advance, in addition, be illustrated in shredding roller 16 in the situation that shredding curve rises and retreat.This be due to, the fore-and-aft direction showing by near the figure making the swaying direction of shredding roller 16 and the expression fell of the above-mentioned position line chart of weaving cotton cloth 10 is consistent, easily makes operator predict the swing of the shredding roller 16 of 1 weave cycle.
Like this, in this variation, at the change curve that shows the displacement of relevant shredding roller 16, be to describe the above-mentioned position line chart of weaving cotton cloth on the diagram region 203 of shredding curve.Therefore,, according to this structure, the first head part (front end of weft yarn W) that operator can confirm injection water is by knitting the variation of shredding amount of front and back in the moment (degree in crank angle) of the optional position in width direction.Therefore, according to this example, the oscillating motion that can easily differentiate shredding roller 16 whether with the fluff generation reason of (through willow) of the problem of weaving that manifests on woven weaving cotton cloth relevant.More specifically, in the situation that the oscillating motion of shredding roller 16 is stably carried out, should not produce the problems referred to above, but sometimes because certain is former thereby produce the disorder of this oscillating motion, shredding amount can sharply change.And, its result, the warp tension ratio that produces sometimes warp thread 3 is high state conventionally, in the situation that injection water contact with warp thread 3 during (picking initial stage or picking tailend) produce this state, warp thread 3 can produce and fluff sometimes.Therefore, by the variation of the shredding amount before and after the above-mentioned any time (the first head part of injection water is by the moment of the generation position of fluffing) of utilizing shredding curve on diagram region 203 to confirm to be represented by the above-mentioned position line figure that weaves cotton cloth, whether the generation reason that can easily differentiate fluffing results from the oscillating motion of shredding roller 16 (the sharply variation of shredding amount).
In addition, in above-mentioned, about change curve, be made as the structure of describing the above-mentioned position line chart of weaving cotton cloth on the diagram region 203 that shows the change curve that the action of weaving associated member to is relevant, but in the present invention, being not limited to like this, can be also the structure of the position line chart of describing on the diagram region 203 making under the consistent state of transverse axis (degree in crank angle) to show the change curve relevant to a plurality of actions of weaving associated member to weave cotton cloth.In addition, as such example, for example, consider the example shown in Fig. 5,6.
Fig. 5 depicts the example of the position line chart of weaving cotton cloth on the diagram region 203 of open curve that makes under the consistent state of degree in crank angle to show the curve relevant to the tension variation of the warp thread 3 of above-described embodiment and above-mentioned (1).According to this example, operator can confirm the opening amount of heald frame 5 and the tension force of warp thread 3 in the moment of the generation position (the optional position Pa of above-described embodiment) that the first head part of injection water fluffs by the problem on weaving simultaneously, and about the generation reason of fluffing, which is chief reason more easily to judge the size of opening amount and the height of warp tension.
In addition, Fig. 6 depicts the example of the position line chart of weaving cotton cloth on the diagram region 203 of shredding curve that makes under the consistent state of degree in crank angle to show the curve relevant to the variation of the tension force of warp thread 3 and above-mentioned (2).In this example, generation reason about fluffing, as the result of having confirmed the curve relevant to the variation of the tension force of warp thread 3, operator is in the situation that the tension force height of the first head part of judging injection water by the warp thread 3 in the moment of the generation position of fluffing is reason, also can confirm the shredding amount of the shredding roller 16 in this moment simultaneously, therefore, can easily judge, when adjusting the tension force of warp thread 3, whether need to carry out the adjustment of the shredding action of shredding roller 16 that this tension force is impacted.
In addition, though the diagram of omission, but can be also following structure, that is, and so that show the position line chart of describing to weave cotton cloth on the curve of variation of tension force of relevant warp thread 3 and the diagram region 203 of the shredding curve of the open curve of above-mentioned (1) and above-mentioned (2) under the consistent state of degree in crank angle.
Like this, by showing the position line chart of describing to weave cotton cloth on the diagram region 203 of a plurality of change curves, the problem on judgement is weaved fluffs more effective aspect the generation reason of (through willow).
In addition, the present invention is also not limited to embodiment arbitrarily described above, only otherwise depart from aim of the present invention, just can carry out various changes.
