Description

The display unit of the picking information that water jet loom is used

Technical field

The utility model relates to for showing the device of picking information of the water jet loom of the injection water picking weft yarn being sprayed by picking mouth from fixed configurations in loom frame.

Background technology

Conventionally, in water jet loom, as disclosed in patent documentation 1, picking mouth fixed configurations is in loom frame.And, utilize inserting weft in the Warp opening that the injection water that sprays from this picking mouth forms to warp thread group being separated into warp thread and lower warp thread by heald frame, make thus weft yarn flight (conveying) to the counter picking of sending yarn side.In addition, after this picking finishes, the weft yarn of picking is driven into fell by the reed swinging along warp thread direction, thus, weaves action (1 cycle of loom) for 1 time and finishes.In addition, said in the application " warp thread direction " is the direction along the direct of travel of warp thread, be take weaving cotton cloth of loom batch side (fell side) as front, the warp thread of take send side as after direction.

In addition, about the swing of reed, more specifically, reed is between fell and going-back position, according to 1 cycle of loom with above-mentioned (main shaft rotation 1 circle of loom during), to carry out 1 reciprocal mode to swing along warp thread direction at progressive position.In addition,, during the picking at loom in 1 cycle, the position of reed becomes the warp thread of the weft yarn of flight and sends side.

But, in water jet loom, as above-mentioned, due to by picking mouth fixed configurations, thus the flight path of the weft yarn of picking at warp thread direction for fixing.In addition, in general water jet loom, it is driven as drive source that the beating device that makes reed carry out oscillating motion is usingd the main shaft of loom, and rotating speed of its action timing and main shaft is set explicitly.Therefore, the responsiveness of beating device and the rotating speed of main shaft are proportional.On the other hand, about weft insertion device, spray the press water of being supplied with by pump from picking mouth, be carried on this injection water and carry weft yarn, therefore, the flying speed of the weft yarn of picking is determined by the pressure of above-mentioned press water (injection water).Therefore,, if this pressure is certain, during the weft yarn of picking 1 picking (1 picking) amount, the flight time of weft yarn is certain and irrelevant with the rotating speed of main shaft.Therefore,, in water jet loom, the pass of the flight path of beating-up and weft yarn ties up to decision picking, and suitably whether aspect is very important.

For example, in the situation that the speed of mainshaft of loom is set as at a high speed, as above-mentioned, responsiveness composition relation due to rotating speed and the beating device of main shaft, therefore, the responsiveness of beating device (swing speed of reed) is accelerated pro rata with the rotating speed of main shaft, consequently, at loom in 1 cycle, reed be positioned at than the flight path of weft yarn by warp thread send side during (time) shorten.On the other hand, as above-mentioned, the flight time of weft yarn is certain and irrelevant with the rotating speed of main shaft, therefore, due to the relation of the rotating speed (responsiveness of beating device) of main shaft and the flight path of weft yarn, in during picking, the flight path of weft yarn and reed become staggered state, sometimes can not normally carry out picking.

Therefore, in water jet loom, consider above-mentioned aspect, carry out starting period to picking or form the relevant setting of the picking movements such as pressure of basic injection water of the flying speed of weft yarn.

Conventionally, the recommendation that these set (initial setting) provides according to loom manufacturer etc. is carried out, but due to the state of the yarn using or weave the environment etc. of factory, this initial setting may not be applicable to, and sometimes need to do further adjustment by the state of this initial setting.And this adjustment operation is carried out test weaving and is implemented by operator.

But, even above-mentioned adjustment operation also very labor intensive and time for skilled worker.Specifically,, when carrying out above-mentioned adjustment operation, the operator first experience based on self changes above-mentioned setting, at this state, carries out test weaving.Then, use the position relationship of the equipment observation reeds such as flash lamp and weft yarn etc., judge that whether this setting is suitable.In addition, now, the reed of picking zero hour and the position relationship of weft yarn be relatively easily from the setting check of the injection timing of picking mouth, but in picking in the situation that of final period, only can be by using the equipment such as flash lamp observe.And, in the result as test weaving, observation, be judged as in the situation that need to carry out further adjusting, again change above-mentioned setting, repeat a series of operation of test weaving, observation and so on.Like this, the above-mentioned adjustment operation of the existing water jet loom only experience based on operator self repeats tentative mistake, also labor intensive and time for skilled worker.

Utility model problem to be solved

Therefore, problem of the present utility model is, provides a kind of for showing method and the device of the picking information for using at the water jet loom of adjusting operation and give operator's information (index) as a reference.

For solving the technical scheme of problem

Under described problem, the utility model provides the display unit of the picking information that a kind of water jet loom uses, the injection water picking weft yarn spraying by the picking mouth from fixed configurations in loom frame, wherein, possess: memory, it stores the picking mouth information of the state that arranges of relevant picking mouth, arithmetic unit, its described picking mouth information based on being stored in this memory, asks by injection water and effectively carries out the initial point of picking valid period of conveying of weft yarn and at least terminal in terminal according to the relation of the oscillating motion with reed, display, it has for showing the display frame of the initial point of the described picking valid period of being obtained by this arithmetic unit and at least terminal of terminal, display controller, the flight path of weft yarn that it describes the described picking mouth information based on being stored in described memory and the swinging track of reed overlap and carry out figure demonstration on the diagram region of the anglec of rotation of the main shaft that transverse axis is described water jet loom take, the swinging track of described reed be at least through with by being disposed at the crossover location that intersects by the described flight path of the weft yarn of the picking mouth picking of fell opposition side and intersecting the definite point of the anglec of rotation of described main shaft in the moment and the track described by this, this display controller shows can grasp the form of the anglec of rotation of described main shaft at least terminal in the initial point of the described picking valid period of being obtained by described arithmetic unit and terminal on described diagram region.

But " the picking mouth information " in the utility model at least comprises the relevant information in setting (configuration) position on the warp thread direction to picking mouth, also comprise as required to the axis of picking mouth towards relevant information.In addition, " flight path of weft yarn " is corresponding with the flight path of described weft yarn, by the position of the front end of the weft yarn by the picking of picking mouth (below also referred to as " flight position ".) warp thread direction on variation as track, represent, take the anglec of rotation that transverse axis is main shaft, and take the longitudinal axis and apart from diagram on the diagram region of the distance of fell, describe on warp thread direction.

In addition, in the utility model, " swing position of the reed of relevant warp thread direction " refer to substantially for by the reed of following the oscillating motion of the rotation of main shaft to change, the position on the warp thread direction that the fell of the part that is positioned at the reed on the position line (path when warp thread is remained silent) of take is benchmark, in other words refers to the distance through the horizontal direction apart from fell of the position line and the staggered position of reed.It depends on following reason.

As above-mentioned, reed carries out oscillating motion, and in most of scope of hunting range, reed tilts with respect to horizontal direction.Therefore under the state that, the distance of the horizontal direction from fell to reed tilts at reed, exist a plurality of.On the other hand, in general water jet loom, picking mouth is positioned at the mode set height position on the position line to observe its axis in picking direction.Therefore, the flight path of weft yarn on above-below direction by with through the roughly the same height and position of the position line.Therefore,, on the basis of relation of grasping the flight path of weft yarn on warp thread direction (horizontal direction) and the position of reed, " swing position of reed " is the distance with the horizontal direction apart from fell of the position through the staggered part of the position line of reed.

In addition, according to water jet loom, in picking direction, observe, the height and position not also sometimes being positioned on the position line at axis arranges picking mouth.In this situation, for example, with regard to the flight path of reed and weft yarn with regard to staggered moment, at reed and staggered part and the reed of weft yarn and through the staggered part of the position line, the distance apart from fell in horizontal direction is different strictly speaking.Therefore,, in this situation, about the swing position of reed, as long as describe the imaginary line that the axis through picking mouth extends in the horizontal direction, set the intervening portion of this imaginary line and reed apart from the distance of fell.But, in the hunting range of reed, the angle of inclination that reed forms with respect to horizontal direction is not too large, therefore, and the position that reed and described imaginary line are staggered and reed and on the impact of picking, almost can ignore through the difference of the distance of the horizontal direction apart from fell of the staggered position of the position line.Therefore, in this situation, for the swing position of reed, also can with the above-mentioned distance being similarly through the horizontal direction apart from fell of the intervening portion of the position line and reed.In addition, situation about tilting with respect to horizontal direction through the position line is also identical, in this situation, for the swing position of reed, can be the distance of the horizontal direction apart from fell of the described Provisional intervening portion of thinking line and reed, can be also the distance through the horizontal direction apart from fell of the intervening portion of the position line and reed.

In addition, " reed swing information " is the information that the form so that the anglec of rotation of the swing position of described reed and the main shaft corresponding with this swing position is associated is set.And " swinging track of reed " is by the variation of swing position of following the reed of weaving action diagrammatic representation and swinging track of obtaining on described diagram region.But, should " swinging track of reed " as above-mentioned if with at least through with by the mode that is disposed at the crossover location that intersects by the flight path of the weft yarn of the picking mouth picking of fell opposition side and intersects the definite point of the anglec of rotation of main shaft in the moment by this, described, its part in addition also can be depicted the degree of the oscillating motion that can be identified as reed as in analog.

In addition, " picking valid period " of the present utility model be about the picking of 1 picking amount, according to the relation of the oscillating motion with reed, by injection water, effectively carry out weft yarn conveying during, by pass through the allocation position of the picking mouth of regulation towards the reed of fell opposition side from fell side on warp thread direction, and take the moment that can start picking by this picking mouth, it is initial point, take moment of contacting with reed at first from a part for the weft yarn of this picking mouth picking during terminal, in other words, be the swing position of the reed flight position in the weft yarn than on warp thread direction more by warp thread send side during.

In addition,, as above-mentioned, in the present embodiment, with the weft yarn W by each picking mouth N1～N4 picking, (be also called for short and make " each weft yarn W " below.) flight path towards the anti-mode of the roughly co-located of yarn side of sending, set the axis of each picking mouth N1～N4 with respect to the inclination of fell 10.In other words, in the present embodiment, with the flight path (flight path) of consistent each weft yarn W of the extended line of the axis with each picking mouth N1～N4, in the specific position mode crossing, that specifically arrived above-mentioned specific position at the weft yarn W of 1 picking amount by the front end of the moment weft yarn W of picking of knitting on width direction and warp thread direction, set the axis of each picking mouth N1～N4 with respect to the inclination of fell 10.Therefore, in the present embodiment, the position of the warp thread direction of the position (in-position of the front end of weft yarn W) that the flight path of above-mentioned each weft yarn W is crossing is used as the common information of each picking mouth N1～N4, and the information of the relevant picking finish time comprising in picking mouth information is set.

And then, in the present embodiment, with the front end of each weft yarn W, with the degree in crank angle of regulation, arrive above-mentioned in-position (below also referred to as " in-position G ".) mode set picking condition.Therefore, to arrive the degree in crank angle of the afore mentioned rules of in-position G be the degree in crank angle corresponding with the flight position of the weft yarn W of picking finish time to the front end of each weft yarn W.Therefore, in the present embodiment, the not only flight position of above-mentioned each weft yarn W (position of warp thread direction), and the degree in crank angle of this regulation be also used as mouth timing (the degree in crank angle Tnzl in Fig. 4) and as the common information of each picking mouth N1～N4, be that the information of relevant picking finish time of comprising in picking mouth information is set.Therefore, as shown in Figure 4, about in-position G, distance on the warp thread direction of fell 10 is distance b, therefore, with regard to the position (coordinate) of 203Shang in-position, diagram region G, the coordinate of transverse axis represents by mouth timing Tnzl, and the coordinate of the longitudinal axis (apart from the distance of fell) is represented by distance b.

In addition, about above-mentioned picking, starting timing Tjet, can be by picking mouth, to be started the degree in crank angle in the moment of the picking of weft yarn W, can be also injection water starts moment of spraying degree in crank angle from picking mouth.; in the picking of general water jet loom; prior to picking mouth, start the moment of the picking of weft yarn W; start the injection of injection water, therefore, in fact by picking mouth, start that the degree in crank angle in the moment of picking of weft yarn W and injection water start moment of spraying degree in crank angle from picking mouth is correctly said and inconsistent; but the difference of these degree in crank angles is little of ignoring when picking; therefore, about picking, start timing Tjet, can set any of these degree in crank angles.

In addition, about above-mentioned picking, start timing Tjet, as above-mentioned, if the swing position of reed 9 is not the situation of side of sending by warp thread than the flight path of weft yarn W, can not carry out picking, therefore, from fell 10 towards the reed 9 of going-back position by carrying out can not starting picking the mouth position of picking mouth of picking.Therefore, can carry out the degree in crank angle in the moment of picking and become reed 9 by the degree in crank angle after the moment of this mouth position.In addition, as above-mentioned, each picking mouth N1, N2, N3, N4 are because mouth position is different, so it is different because of each picking mouth to carry out the degree in crank angle of picking, approaches the picking mouth N4 of fell 10 most due in each picking mouth, reed 9 is the earliest by Qi Zui position, so can carry out the earliest picking in each picking mouth, apart from fell 10 picking mouth N1 farthest, due in each picking mouth, reed 9 is the latest by this mouth position, so can carry out the latest picking in each picking mouth.

On the other hand, with regard to start the relation of opening amount of timing Tjet and Warp opening 6 with picking with regard to, in the moment that starts picking, the size of the degree that the opening amount of Warp opening 6 need to not impact picking for the interference of upper warp thread 3a and lower warp thread 3b and injection water, but, aspect the relation of each picking mouth N1, N2, N3, the mouth position of N4 and the opening amount of Warp opening 6, mouth position more approaches fell 10, the opening amount of Warp opening 6 is in the same time less, therefore, the picking mouth that approaches fell 10, picking starts more late.Therefore, in the present embodiment, consider the swing position of reed 9 and the opening amount of Warp opening 6 the two, about picking, start timing Tjet, each picking mouth N1, N2, N3, N4 are set to identical degree in crank angle.And, in the present embodiment, about this picking, start timing Tjet, as shown in Figure 4, the reed 9 that is set as moving back towards the postpone of finally giving up the throne from fell 10 is by the degree in crank angle the mouth position in the picking mouth N1 apart from fell 10 position farthest.

In addition, about this picking, start timing Tjet, in above-mentioned, be made as reed 9 by according to and the relation of the swing position of reed 9 can carry out the degree in crank angle behind the mouth position of picking mouth N1 at the latest of the moment of picking of weft yarn W, but also can be made as reed 9 by the moment (moment of arrival mouth position) of the mouth position of picking mouth N1.

Specifically, with regard to the picking of carrying out with regard to picking mouth N1, strictly speaking, at the front end of the weft yarn W by picking mouth N1 picking, arrive the moment of the position of sending yarn side of knitting the reed 9 in width direction, so long as the swing position of reed 9 is positioned at and slightly sends the such picking of side by warp thread than the front position of this weft yarn W and start timing Tjet, can carry out picking.And, picking mouth N1 knit in width direction, leave reed 9 send the setting of yarn side, by picking mouth N1, started between the moment of picking of weft yarn W and moment that the front end of weft yarn W arrives the position of sending yarn side of knitting the reed 9 in width direction Cun Time with poor.Therefore, even if the moment that arrives the mouth position of picking mouth N1 at reed 9 starts the picking of the weft yarn W that picking mouth N1 carries out, in the moment that arrives the position of sending yarn side of reed 9 at the front end of weft yarn W, the swing position of reed 9 is also positioned at than the front position of weft yarn W more sends side by warp thread.Therefore, even if the moment that arrives the mouth position of picking mouth N1 at reed 9 starts picking, also can carry out picking by picking mouth N1, therefore, the moment that also reed 9 can be arrived to the mouth position of picking mouth N1 start timing Tjet as picking and set.

And then, in the present embodiment, with axis, to fell 10, roll oblique mode and be provided with picking mouth N1, therefore, the position of warp thread direction of its front end in the moment that the front end of weft yarn W arrives the position of sending yarn side of knitting the reed 9 in width direction than the mouth position of picking mouth N1 more by fell 10 sides.Therefore, according to the relation of the swing position with reed 9, can carry out weft yarn W picking time be engraved in the situation of the present embodiment as arrive moment a little earlier in the moment of the mouth position of picking mouth N1 than reed 9, also can using this moment as picking, start timing Tjet and set.But, when the front end of the weft yarn W by picking mouth N1 picking arrives moment of the position of sending yarn side of knitting the reed 9 in width direction and reed 9 difference by the moment of this position when too small, likely cause picking bad etc., therefore, picking starts the moment that the preferred reed 9 of timing Tjet arrives the mouth position of picking mouth N1.

In addition, about above-mentioned mouth timing Tnzl, as above-mentioned, it is the degree in crank angle that the front end of weft yarn W arrives the moment of the above-mentioned in-position G flight position of the distance b of fell 10 (on the warp thread direction apart from), but in the present embodiment, with the swing position of this mouth timing Tnzl and the reed 9 that advances towards fell 10 from going-back position, arrive the picking condition of setting the picking that each picking mouth N1～N4 carries out apart from the consistent mode of degree in crank angle in moment of the position of fell 10 distance b.Therefore, in the present embodiment, the flight path of the swinging track of reed 9 and weft yarn W is staggered at the in-position G of above-mentioned each weft yarn W, and the swinging track of reed 9 is described in the mode through this in-position G.

In the water jet loom 1 of above the present embodiment, describe in detail below the initial point of the picking valid period that arithmetic unit 103 carries out and terminal and the acquiring method of picking valid period.

First, about the initial point of picking valid period, as above-mentioned, the picking of the weft yarn W that each picking mouth N1～N4 carries out starts timing Tjet and determines by setting, therefore, the degree in crank angle of the initial point of the picking valid period of each picking mouth N1～N4 is that picking starts timing Tjet.

In addition, about the terminal of picking valid period, the degree in crank angle in the moment at first that the reed 9 advancing towards fell 10 sides from going-back position and the weft yarn W of picking are staggered becomes the terminal of picking valid period.; staggered with the reed 9 advancing towards fell 10 sides towards the anti-weft yarn W at least a portion of yarn side flight of sending; flying speed sharply reduces (or stopping) thus, and therefore, the terminal of picking valid period is reed 9 and the weft yarn W degree in crank angle in the staggered moment at first.But, in the present embodiment, as above-mentioned, because the flight path (flight path) of the weft yarn W by each picking mouth N1, N2, N3, N4 picking tilts with respect to fell 10, thus reed 9 because of the inclination of the fell 10 with respect to above-mentioned flight path (flight path) with respect to the weft yarn W of 1 picking amount of picking near the part (rearward end) its front end or picking mouth interlock at first.

Particularly, as shown in Figure 4, picking mouth N1, N2 roll oblique mode with its axis towards fell 10 and arrange, and the flight path of the weft yarn W of picking is along with sending yarn side and approach from mouth position to fell 10 towards counter.Therefore, by the weft yarn W of picking mouth N1, N2 picking, at front end, arrive in-position G (front end is staggered with reed 9) before, rearward end and reed 9 interlock.In addition, because this intervening portion is near picking mouth N1, N2, so the position on this warp thread direction can exchange with the setting position of picking mouth N1, N2, this constantly staggered degree in crank angle becomes degree in crank angle n1, the n2 as the mouth set positions of above-mentioned picking mouth N1, N2.

On the other hand, the mode that picking mouth N3, N4 tilt towards anti-fell 10 sides (warp thread is sent side) with its axis arranges, and the flight path of the weft yarn W of picking is along with sending yarn side and leave with respect to fell 10 from mouth position towards counter.Therefore, first staggered at in-position G and reed 9 by the front end of the weft yarn W of picking mouth N3, N4 picking.That is, the weft yarn W by picking mouth N3, N4 picking interlocks in rearward end and reed 9, and (the mouth position of reed 9 arrival picking mouth N3, N4) before, front end and reed 9 are staggered.And this constantly staggered degree in crank angle becomes mouth timing Tnzl.

Therefore, terminal about the picking valid period, arithmetic unit 103 is for each picking mouth N1～N4, by the front end of the weft yarn W of picking arrive the moment of in-position G degree in crank angle, be rear end and the reed 9 of weft yarn W of mouth timing Tnzl and the picking degree in crank angle in the staggered moment, the mouth position with the degree in crank angle setting of the present embodiment compares, and the less side of this angle is made as to the terminal of picking valid period.

In addition, arithmetic unit 103 is asked the picking valid period according to initial point and terminal as the above-mentioned picking valid period of obtaining for each picking mouth N1, N2, N3, N4.In addition, the degree in crank angle (picking starts timing Tjet) that this picking valid period deducts above-mentioned initial point by the degree in crank angle from above-mentioned terminal is asked for, and the calculating formula for this is stored in to arithmetic unit 103.The calculating of the picking valid period of each picking mouth N1, N2, N3, N4 is specific as follows.

About picking mouth N1, as above-mentioned, for the rear end of the weft yarn W of picking, with degree in crank angle constantly the earliest, interlock with reed 9, so become the terminal of picking valid period as the degree in crank angle n1 of mouth set positions.Therefore, the picking valid period c1 of picking mouth N1 calculates by following calculating formula.

Picking valid period c1=degree in crank angle n1-picking starts timing Tjet

Equally, about picking mouth N2, also become the terminal of picking valid period as the degree in crank angle n2 of mouth set positions, the picking valid period c2 of picking mouth N2 calculates by following calculating formula.

Picking valid period c2=degree in crank angle n2-picking starts timing Tjet

In addition, about picking mouth N3, as above-mentioned, because the front end of the weft yarn W of picking is staggered with degree in crank angle and the reed 9 in moment at first, so the degree in crank angle corresponding with above-mentioned in-position G is the terminal that mouth timing Tnzl becomes the picking valid period.Therefore, the picking valid period c3 of picking mouth N3 calculates by following calculating formula.

Picking valid period c3=mouth timing Tnzl-picking starts timing Tjet

Equally, about picking mouth N4, the degree in crank angle corresponding with above-mentioned in-position G is the terminal that mouth timing Tnzl also becomes the picking valid period, and the picking valid period c4 of picking mouth N4 calculates by following calculating formula.

Picking valid period c4=mouth timing Tnzl-picking starts timing Tjet

Secondly, the effect of the picking information display device 100 in the present embodiment structure is described.Operator tries to spin to have set the state of picking condition according to initial setting, result is, be judged as in situation about need to adjust picking etc., operator uses picking information display device 100, by display 106, confirm the picking valid period of each picking mouth under initial setting state, ask adjustment amount.

Operator confirms the picking valid period under the state of this initial setting in order to set the standard of above-mentioned adjustment amount, first operate the aforesaid operations button of the loader 101 of picking information display device 100.Thus, in picking information display device 100, from loader 101 to the arithmetic unit 103 output display command signals that show arithmetic unit 107.

Arithmetic unit 103 is when inputting above-mentioned idsplay order signal, as for asking the information of the value of the initial point of picking valid period and terminal and this picking valid period, from memory 102, read picking mouth information, ask initial point and the terminal of the picking valid period of each picking mouth N1～N4, and ask picking valid period c1～c4, and initial point, terminal and the picking valid period c1～c4 of the picking valid period of each picking mouth N1～N4 that this is obtained are to display controller 105 outputs.

Display controller 105 is during from the initial point of the picking valid period of above-mentioned each picking mouth N1～N4 obtaining of arithmetic unit 103 input, terminal and each picking valid period c1～c4, as shown in Figure 5, the hurdle of the regulation of the display field 201 on the initial point of the picking valid period of above-mentioned each picking mouth N1～N4 obtaining, terminal and the right side of being located at diagram region 203 of each picking valid period c1～c4 in the display frame 200 of display 106 is shown.

In addition, display controller 105 is read picking mouth information from memory 102, and based on describing and show the flight path of weft yarn W on this picking mouth information diagram region 203 in display frame 200, and the swinging track of reed 9 is described to show by the flight path of weft yarn W of picking mouth N1 picking and the circular-arc curve of the crossover location of mouth timing Tnzl of fell opposition side as passing by being disposed on above-mentioned diagram region 203.In addition, Details as Follows for the plotting method of the swinging track of the flight path of weft yarn W and reed 9.

As above-mentioned, in the present embodiment, 2 relevant information of flight position on flight path based on to weft yarn W are described the flight path of weft yarn W, therefore, in picking mouth information, as the information relevant to picking zero hour, for the initial point of the flight path (flight path) of each weft yarn W, set the mouth position of each picking mouth N1 as the flight position of the weft yarn W of picking zero hour, N2, N3, N4.

Specifically, as above-mentioned, as mouth position, set reed 9 by being equivalent to degree in crank angle n1, n2, n3, the n4 in the moment of the swing position of mouth position, therefore the distance a1 apart from fell 10, asking for based on degree in crank angle n1, n2, n3, n4 and reed swing information, a2, a3, a4 become the coordinate of the longitudinal axis of the initial point of above-mentioned flight path.

Therefore, according to the mouth position (apart from distance a1, a2, a3, the a4 of fell 10) of this each picking mouth N1, N2, N3, N4 and the picking that is set in memory 102 as above-mentioned weaving condition (picking condition), start timing Tjet (degree in crank angle when picking starts), the coordinate of the initial point of the above-mentioned flight path on specific above-mentioned diagram region 203.

In addition, as above-mentioned, in picking mouth information, as the relevant picking information of the finish time, the flight position that is set with the weft yarn W of picking finish time for the terminal of the flight path (flight path) of each weft yarn W is the in-position G (apart from the position of the distance b of fell 10) of the front end of weft yarn W and as the mouth timing Tnzl of the degree in crank angle in this moment, and the coordinate of the terminal of the above-mentioned flight path on above-mentioned diagram region 203 is specific according to these information.Therefore, display controller 105 is based on starting according to picking mouth information and picking the initial point of above-mentioned flight path and the coordinate of terminal that timing Tjet obtains, as the flight path through describing each weft yarn W on the diagram region 203 of this straight line of 2 in display frame 200.

Swinging track about reed 9, in the present embodiment, as above-mentioned, describe the circular-arc curve of the oscillating motion of analog representation reed 9, this circular-arc curve is described as follows,, the above-mentioned point that beats up (apart from the point of the distance 0 of fell 10) of take is initial point (0 °) and terminal (360 °), at least through the swinging track of reed 9 with by being disposed at by the crossover location (apart from the distance b of fell 10) of the flight path of the weft yarn W of the picking mouth N1 picking of fell opposition side and the definite point (in-position G) of the anglec of rotation (mouth timing Tnzl) of main shaft 12 constantly of intersecting thereof.

In addition, the reason that the swinging track of reed 9 is described as circular-arc curve is, because in general loom, reed 9 is supported by rocker, this rocker drives by take the crank mechanism reciprocating rotary that spindle motor M is drive source, so, in the situation that because of the consistent structure of the top dead-centre of crank-motion and the swing of bottom dead centre and reed 9 limit (progressive position and going-back position) for example of the relation with crank-motion, the oscillating motion of reed 9 is to describe sine curve with the relation of degree in crank angle.Therefore, in the situation that take the variation in 1 cycle of the loom of the swing position distance of fell 10 (on the warp thread direction apart from) that transverse axis describes reed 9 on the diagram region 203 that degree in crank angle and the longitudinal axis of take are the distance apart from fell 10, this track is used as circular-arc curve and describes.

But, the swinging track of reed 9 may not be limited to sinusoidal circular-arc curve due to the structure of crank mechanism, in addition, in the utility model, if the swinging track of reed 9 is only correctly described the flight path of weft yarn W and the relevant part (the staggered moment) of reed 9 of carrying out oscillating motion, for comprising above-mentioned other parts of beating up a little, so long as can show that reed 9 is with respect to the degree of the oscillating motion of the flight path of weft yarn W.Therefore, in the present embodiment, the swinging track of reed 9 is through being disposed at by the actual staggered point of the picking mouth N1 of fell opposition side and reed 9, being in-position G (the transverse axis coordinate: mouth timing Tnzl/ ordinate of orthogonal axes: b), and comprise the circular-arc curve that above-mentioned its outer part of beating up is a little used as the simulation different from the swinging track of actual reed 9 and describe of the weft yarn W of the present embodiment.And as shown in Figure 5, display controller 105 is described the swinging track of this reed 9 on the diagram region 203 in display frame 200.

In addition, swinging track about this reed 9, as above-mentioned, in the present embodiment, because starting timing Tjet, picking is set to the degree in crank angle behind the mouth position that reed 9 passed through picking mouth N1, so the flight path of weft yarn W and the swinging track of reed 9 by picking mouth N1 picking are only staggered at above-mentioned in-position G, but in the situation that being started to timing Tjet, picking is set as the moment that reed 9 arrives the mouth position of picking mouth N1, on showing, the swinging track of reed 9 and by the flight path of the weft yarn W of picking mouth N1 picking in picking starting position (transverse axis coordinate: picking starts timing Tjet/ ordinate of orthogonal axes: a1) also interlock.Therefore,, in this situation, the swinging track of reed 9 is described also to pass the mode of the coordinate of picking starting position.In addition, as the present embodiment, the swinging track of reed 9 is not limited to simulation and describes, and also can as the consistent information of oscillating motion of the reed 9 with actual, describe based on the swing position of degree in crank angle and reed 9 being set explicitly to the reed swing information obtaining.

And then, in the present embodiment, as the above-mentioned diagram region 203 of having described the flight path of weft yarn W and the swinging track of reed 9 on, the form that visually can grasp with operator is described initial point and terminal and each picking valid period c1～c4 of (demonstration) picking valid period, and display controller 105 is also described initial point and terminal and each picking valid period c1～c4 of picking valid period on diagram region 203.In addition, the initial point of these picking valid periods, terminal and each picking valid period c1～c4's draws and shows in detail as follows.

As above-mentioned, the initial point of picking valid period is that common picking starts timing Tjet at each picking mouth N1～N4, therefore, in the present embodiment, as shown in Figure 5, the line chart parallel with the longitudinal axis (ordinate) described in the position that picking starts the degree in crank angle of timing Tjet that is equivalent on the transverse axis in diagram region 203, and, this for position mark " Tjet " represent.And, in the present embodiment, as above-mentioned, in display frame 200, be located at the display field 201 on the right side in diagram region 203, this degree in crank angle (in illustrated example being 100 °) is shown at the display field that is designated as " picking starts timing Tjet ".Therefore, in this display frame 200, the initial point of picking valid period is shown can grasp the form of its degree in crank angle.

Equally, terminal about the picking valid period, the in the situation that of picking mouth N1, N2, as above-mentioned, for being equivalent to respectively degree in crank angle n1, the n2 of mouth position, therefore, as shown in Figure 5, the line chart parallel with the longitudinal axis (ordinate) described in position at degree in crank angle n1, the n2 of the transverse axis in diagram region 203, and in this position display mark " n1 ", " n2 " respectively.And, same as described above, at display field 201, this degree in crank angle (being respectively 265 °, 275 ° in illustrated example) is shown being designated as " mouth position n1 " and the hurdle of " n2 ".

In addition, the in the situation that of picking mouth N3, N4, as above-mentioned, owing to being common mouth timing Tnzl (in-position G), so as shown in Figure 5, the position of the degree in crank angle that is equivalent to mouth timing Tnzl on the transverse axis in diagram region 203, describes the line chart parallel with the longitudinal axis (ordinate), and shows with mark " Tnzl " in this position.And, same as described above, at display field 201, this degree in crank angle (in illustrated example being 280 °) is shown on the hurdle that is designated as " mouth timing Tnzl ".Like this, the terminal of picking valid period also shows can grasp the form of its degree in crank angle in display frame 200.

In addition, each picking valid period c1～c4 be from above-mentioned initial point to above-mentioned terminal during, as shown in Figure 5, on diagram region 203, for stepping up to state, be depicted as the ordinate of initial point and the line chart between the above-mentioned ordinate that is depicted as terminal, each picking mouth is described and the line chart (horizontal line) that two ends is made as to the transverse axis of arrow.In addition, above each line chart of describing at this, show mark " c1 ", " c2 ", " c3 ", " c4 " that represents respectively the corresponding picking valid period.And, in the present embodiment, at above-mentioned display field 201, the crank angle (being respectively 165 °, 175 °, 180 °, 180 ° in illustrated example) that represents each picking valid period is shown on the hurdle that is designated as " picking valid period " " c1 ", " c2 ", " c3 ", " c4 ".

In addition, as mentioned above, in the present embodiment, the initial point and terminal and each picking valid period c1～c4 that on the diagram region 203 that shows the flight path of weft yarn W and the swinging track of reed 9, show the picking valid period, their degree in crank angle can be grasped on picture 200, but in the utility model, the initial point of the picking valid period in them and each picking valid period c1～c4 may not show.

This be because, the initial point of picking valid period starts timing Tjet as above-mentioned for the common picking of each picking mouth N1～N4, this is set by operator, therefore, instead often do not show, and is grasped by operator self.In addition, the degree in crank angle of picking valid period by the terminal from the picking valid period deducts above-mentioned picking to start timing Tjet and obtains, even if do not show, as long as can grasp the terminal of picking valid period, just can by simple calculating, easily obtain thus.

But for the terminal of picking valid period, operator is for it is grasped, conventionally must use stroboscope etc. to confirm in actual picking, this grasp operation is very numerous and diverse.Therefore,, in the utility model, for the terminal of this picking valid period, on the picture 200 of display 106, can grasp its degree in crank angle.

Like this, as shown in Figure 5, on the diagram region 203 of display frame 200, show and represent that flight path, the swinging track of reed 9, the initial point of picking valid period of weft yarn W are that picking starts the line chart of timing Tjet and represents that the terminal of picking valid period is the line chart of degree in crank angle n1, n2 and mouth timing Tnzl.In addition, display field 201 in display frame 200, with degree in crank angle, show picking valid period c1, c2, c3, c4, and show that above-mentioned picking starts the degree in crank angle of timing Tjet and mouth timing Tnzl and as degree in crank angle n1, n2, n3, the n4 of mouth set positions.

Therefore, in the present embodiment, operator can grasp the initial point of picking valid period and the degree in crank angle of terminal, the value of picking valid period (length) by observing diagram region 203 shown in above-mentioned display frame 200 and display field 201.

As above, first operator confirms that by the demonstration from display frame 200 the picking valid period c1～c4 of each picking mouth N1～N4 initial setting state grasps present situation in picking adjustment.And, whether operator has and needs arbitrary project of adjusting to inquire into the setting item of needs adjustment, such as the value n1～n4 of the mouth position of each picking mouth N1～N4 or the setting that picking starts timing Tjet etc., and uses loader 101 change should to become the operation of setting value of the setting item of adjustment object.

And, by this operation, upgrade the setting value that is stored in the setting item that becomes above-mentioned adjustment object in memory 102.Then, when operator operates the action button of loader 101 again, picking information display device 100 utilizes arithmetic unit 103 to ask above-mentioned setting value picking valid period c1～c4 after changing by order same as described above, and utilize display controller 105 on diagram region 203, to describe the flight path of weft yarn W and the swinging track of reed 9, and then describe to represent initial point and terminal and the line chart of picking valid period of picking valid period, and the display field in display frame 200 201 shows each degree in crank angles.

Its result, operator can confirm above-mentioned setting picking valid period c1～c4 after changing by the demonstration of display 106.And, in judgement, in the situation that the picking valid period c1～c4 of the setting value changing according to the result of this confirmation is suitable, carry out picking, based on this setting value, carry out actual adjustment, and carried out, after the test weaving for confirming, starting to weave.In addition, result in the demonstration by confirmation display 106, the picking valid period c1～c4 of basis setting value is after changing judged as in the situation that can not suitablely carry out picking, corresponding setting item and the setting value thereof of adjusting inquired into again, on picking information display device 100, to reflecting that setting item and the setting value thereof of this discussion result carry out a series of operation, can reaffirm thus the flight path of weft yarn W and the swinging track of reed 9, the initial point of picking valid period and terminal and picking valid period c1～c4.

Above, an embodiment of the present utility model is illustrated, but the utility model is not limited to above-described embodiment, also can be used as following variation and implement.

In the above-described embodiments, illustrated and applied the example of the demonstration of picking information of the present utility model to possessing the water jet loom of 4 picking mouth N1～N4, but apply water jet loom of the present utility model and be not limited to such loom, also go for possessing 3 below or the water jet loom of 5 above a plurality of picking mouths.In addition, be not limited to possess the loom of a plurality of picking mouths, also go for only possessing the water jet loom of 1 picking mouth.In addition,, in the situation that picking mouth is only 1,1 picking mouth of " being disposed at the picking mouth that leans on fell opposition side most " of the present utility model is equivalent to this 1 picking mouth.

In addition, in the above-described embodiments, the situation that possesses a plurality of picking mouths (picking mouth N1～N4) for water jet loom, the picking of each picking mouth is started to timing Tjet and be set as identical degree in crank angle, and the picking of the initial point of picking valid period being fixed on to this setting starts timing Tjet.But, in the utility model, be not limited to this, in possessing the water jet loom of a plurality of picking mouths, also the picking of 1 above picking mouth can be started to timing Tjet sets in the early stage or adjustment afterwards in be set as starting from the picking of other picking mouth the degree in crank angle that timing Tjet is different.In addition, in this situation, also can ask according to picking mouth information (flight path of weft yarn) and reed swing information (swinging track of reed) initial point of the picking valid period that will ask for.

Specifically, as above-mentioned, can carry out picking time be engraved in each picking mouth reed 9 for moving back towards the postpone of finally giving up the throne from fell 10 (progressive position) by the degree in crank angle after the moment of the mouth position corresponding with this picking mouth.For example in the case of the above embodiments, if starting timing Tjet, the picking of picking mouth N1 of take considers as benchmark, with reference to the picking postponing most the picking mouth N1 by mouth position of reed 9 constantly and set picking mouth N2～N4, start timing Tjet, but for picking mouth N2～N4, according to the relation of the swing position with reed, can start picking starting the Zao moment of timing Tjet than the picking of picking mouth N1.

On the other hand, about picking, start timing Tjet, also must consider the relation with the opening amount of Warp opening 6, owing to being positioned at than picking mouth N1, more by the picking mouth N2～N4 of fell side, in the opening amount of Warp opening 6 position less than picking mouth N1, carry out picking, so according to the relation with this opening amount, also sometimes the picking of picking mouth N2～N4 is started to timing Tjet and is set as starting the slow moment of timing Tjet than the picking of picking mouth N1.Like this, in water jet loom, be not limited to that the picking of a plurality of picking mouths is started to timing Tjet and be set as regularly identical timing (degree in crank angle), the kind of the weaving condition that also basis sets sometimes and the weft yarn of picking etc. is set with different timings each picking mouth.And the adjusting stage before weaving beginning, this picking sometimes starts timing also can become adjustment object.

In this situation, initial point about the picking valid period, also can same as the previously described embodimentsly be that the picking setting starts timing Tjet, but in the situation that starting the setting of timing Tjet, this picking is accompanied by adjustment, in order to set the standard of this adjustment, this initial point also can be obtained based on picking mouth information (mouth position) and reed swing information (swing position of reed).In addition,, in this situation, the terminal of obtaining in the initial point that the picking valid period is obtained according to this and above-described embodiment is calculated.In addition, as above-mentioned, in order to be made as picking, starting the standard of the adjustment of timing Tjet, and according to picking mouth information and reed swing information, ask in the situation of initial point of picking valid period, the terminal of picking valid period not only, at least the initial point of this picking valid period of obtaining, also preferably shows on the diagram region 203 of the display frame 200 of picking information display device 100 can grasp the form of degree in crank angle.

In addition, the utility model is also not limited to arbitrary embodiment described above, only otherwise depart from aim of the present utility model, just can carry out various changes.
