Description

The display packing of the picking information of water jet loom and device

Technical field

The present invention relates to for display by from fixed configurations in loom frame picking mouth spray injection water picking weft yarn The method and device of picking information of water jet loom.

Background technology

Generally, in water jet loom, as disclosed in patent documentation 1, picking mouth fixed configurations is in loom frame.And And, utilize from the injection water of this picking mouth injection to the warp thread by heald frame, warp thread group being separated into upper warp thread and lower warp thread and formed Opening inserts weft yarn, thus carries out making weft yarn flight (conveying) to the anti-picking sending yarn side.It addition, after this picking terminates, throw The weft yarn of latitude is driven into fell by the reed swung along warp thread direction, and thus, 1 weaving action (1 cycle of loom) terminates.This Outward, " warp thread direction " described in the application is the direction of the direct of travel along warp thread, is to batch side (knit with weaving cotton cloth of loom Mouthful side) be front, send the direction after side is with warp thread.

It addition, about the swing of reed, more specifically, reed progressive position i.e. fell and between going-back position according to By the above-mentioned loom 1 cycle period of 1 circle (main shaft of loom rotate) carry out 1 time reciprocal in the way of put along warp thread direction Dynamic.Additionally, during picking in loom 1 cycle, side sent by the warp thread of the weft yarn that the position of reed becomes flight.

But, in water jet loom, as above-mentioned, due to by picking mouth fixed configurations, so the flying of the weft yarn of picking Walking along the street footpath is fixing at warp thread direction.It addition, in general water jet loom, make reed carry out the beating device of oscillating motion Being driven using the main shaft of loom as driving source, its action timing sets explicitly with the rotating speed of main shaft.Therefore, beating device Speed of action proportional to the rotating speed of main shaft.On the other hand, about Weft insertion device, the pressure supplied by pump is sprayed from picking mouth Water, is carried on this injection conveying waterborne weft yarn, and therefore, the flight speed of the weft yarn of picking is by the pressure of above-mentioned press water (injection water) Power determines.Therefore, if this pressure is certain, then during the weft yarn that picking 1 picking (1 picking) is measured the flight time of weft yarn certain and Unrelated 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 determine to throw Whether suitable latitude aspect be critically important.

Such as, in the case of the speed of mainshaft of loom being set as at a high speed, as above-mentioned, due to rotating speed and the beating of main shaft The speed of action composition relation of device, therefore, the speed of action (swing speed of reed) of beating device and the rotating speed of main shaft Proportionally accelerating, as a result of which it is, in loom 1 cycle, reed is positioned at the flight path than weft yarn and sends the period of side by warp thread (time) shortens.On the other hand, as above-mentioned, the flight time of weft yarn is necessarily unrelated with the rotating speed of main shaft, accordingly, because main shaft Rotating speed (speed of action of beating device) and weft yarn flight path relation and during picking in the flight path of weft yarn Become staggered state with reed, sometimes can not be normally carried out picking.

Therefore, in water jet loom, it is considered to above-mentioned aspect, carry out starting period with picking or constituting the flight of weft yarn The setting that the picking movements such as the pressure of the injection water on the basis of speed are relevant.

Generally, these recommendations setting (initial setting) and providing according to loom manufacturer etc. are carried out, but due to use The state of yarn or the environment etc. of weaving plants, this initial setting is not necessarily suitable for, it is sometimes desirable to by the state of this initial setting do into The adjustment of one step.And, this adjustment operation is carried out test weaving by operator and implements.

But, above-mentioned adjustment operation is even for the most very labor intensive and time for skilled worker.Specifically, exist When carrying out above-mentioned adjustment operation, operator is primarily based on the experience of self and changes above-mentioned setting, carries out test weaving in this state.So After, use the equipment such as flash lamp to observe reed and the position relationship etc. of weft yarn, it is judged that this setting is the most suitable.It addition, now, picking The reed of start time and the position relationship of weft yarn are relatively easily from the setting check of the injection timing of picking mouth, but final in picking In the case of, it is only capable of by using the equipment such as flash lamp to observe.And, as test weaving, the result of observation, it is judged that for needing In the case of further adjusting, again change above-mentioned setting, repeat a series of operation of test weaving, observation etc. So, the experience that the above-mentioned adjustment operation of existing water jet loom is based only upon operator self repeats tentative mistake, for Also labor intensive and time for skilled worker.

Therefore, the problem of the present invention is, it is provided that a kind of for showing for giving operator conduct in adjusting operation The method and device of the picking information of the water jet loom of the information (index) of reference.

For solving the technical scheme of problem

Under described problem, the present invention provides the display packing of the picking information of a kind of water jet loom, by from Fixed configurations in loom frame picking mouth spray injection water picking weft yarn, wherein, by based on picking mouth state is set The flight path of the weft yarn of relevant picking mouth information portrayal is in the anglec of rotation with main shaft that transverse axis is described water jet loom Diagram region on the display picture of degree shows, and, relevant to the swinging track of reed is graphically displayed at described showing Show the display that overlaps on the diagram region of picture with the described flight path of weft yarn, the swinging track of described reed be at least across with by Crossover location that the described flight path of the weft yarn being configured at picking mouth picking by fell opposition side is intersected and by this intersection Point that the anglec of rotation of the described main shaft in moment determines and the track depicted, it addition, based on described picking mouth information and by institute The anglec of rotation stating main shaft and the reed swing information being set explicitly about the swing position of the reed of warp thread direction, according to The relation of the oscillating motion with reed seeks initial point and the terminal of the picking valid period of the conveying effectively being carried out weft yarn by injection water In at least terminal, and on described display picture, show this end obtained so that the form of the anglec of rotation of described main shaft can be grasped Point.

It addition, the present invention provides the display device of the picking information of a kind of water jet loom, by from fixed configurations In the injection water picking weft yarn that the picking mouth of loom frame sprays, wherein, possessing: memorizer, it stores setting of relevant picking mouth The picking mouth information of configuration state；Arithmetical unit, it is based on being stored in the described picking mouth information of this memorizer, according to the swing with reed The relation of motion ask by injection water effectively carry out in the initial point of picking valid period of conveying of weft yarn and terminal the most whole Point；Display, it has in the initial point of described picking valid period and terminal obtained by this arithmetical unit for display at least The display picture of terminal；Display controller, it is by weft yarn based on the described picking mouth information portrayal being stored in described memorizer Flight path and the swinging track of reed overlap on the diagram region with the anglec of rotation that transverse axis is described main shaft and carry out figure Display, the swinging track of described reed be at least across with the institute by the weft yarn being configured at picking mouth picking by fell opposition side State crossover location and the point that determined by the anglec of rotation of the described main shaft in this intersection moment that flight path intersects and the rail described Mark, this display controller by by least terminal in the initial point of the described picking valid period obtained described arithmetical unit and terminal with The form of the anglec of rotation that can grasp described main shaft shows on described diagram region.

But, " the picking mouth information " in the present invention includes at least and setting (configuration) position on the warp thread direction of picking mouth Put relevant information, the most also comprise to the axis of picking mouth towards relevant information.It addition, " the flight rail of weft yarn Mark " corresponding with the flight path of described weft yarn, the position of the front end of the weft yarn by picking mouth picking (is also referred to as below " flight position ".) warp thread direction on change be indicated as track, in the anglec of rotation with transverse axis as main shaft, and with The longitudinal axis is that on the diagram region of the distance on warp thread direction away from fell, diagram is described.

It addition, in the present invention, " about the swing position of reed of warp thread direction " substantially refers to for by with main The oscillating motion of the rotation of axle and the reed that changes, to be positioned at knitting of the part of the reed on Warp line (path when warp thread is remained silent) The position on warp thread direction on the basis of Kou, in other words refer to the horizontal direction away from fell of the Warp line position staggered with reed Distance.It depends on following reason.

As above-mentioned, reed carries out oscillating motion, and in most of scope of hunting range, reed tilts relative to horizontal direction.Cause This, the distance of the horizontal direction from fell to reed exists multiple when reed tilts.On the other hand, in general water injection In formula loom, picking mouth is to look up set height position in the way of its axis is positioned on Warp line in picking side.Therefore, The flight path of weft yarn is in the vertical direction by the height and position roughly the same with Warp line.Therefore, warp thread side is being grasped On the basis of the relation of the flight path of the weft yarn in (horizontal direction) and the position of reed, " swing position of reed " is and reed The distance of the horizontal direction away from fell of the position of the part that Warp line is staggered.

Additionally, according to water jet loom, look up in picking side, the most sometimes it is not positioned on Warp line at axis Height and position arranges picking mouth.In the case of Gai, such as the moment that the flight path of reed with weft yarn interlocks, at reed and weft yarn The part that staggered part and reed interlock with Warp line, in horizontal direction, the distance away from fell is different strictly speaking.Cause This, in the case of being somebody's turn to do, about the swing position of reed, as long as describing the imagination extended in the horizontal direction through the axis of picking mouth Line, sets this imaginary line intervening portion with reed distance away from fell.But, in the hunting range of reed, reed relative to The angle of inclination that horizontal direction is formed is less big, and therefore, position and reed that reed is staggered with described imaginary line interlock with Warp line The difference of distance of the horizontal direction away from fell of position the impact of picking almost can be ignored.Therefore, in the case of being somebody's turn to do, for For the swing position of reed, it is also possible to be the horizontal direction away from fell of Warp line and the intervening portion of reed as described above Distance.It addition, Warp line is the most identical relative to the situation that horizontal direction tilts, should in the case of, for reed swing position and Speech, can be described in think the distance of the horizontal direction away from fell of intervening portion of line and reed, it is also possible to be Warp line with The distance of the horizontal direction away from fell of the intervening portion of reed.

It addition, " reed swing information " is with by the swing position of described reed and the main shaft corresponding with this swing position The information that the form that the anglec of rotation is associated is set.And, " swinging track of reed " is by the reed with weaving action The swinging track that change figure on described diagram region of swing position represents and obtains.But, it is somebody's turn to do " swinging track of reed " As long as above-mentioned to intersect at least across with by the flight path of the weft yarn being configured at picking mouth picking by fell opposition side Crossover location and the mode of point determined by the anglec of rotation of the main shaft in this intersection moment describe, the part beyond it is also The degree that can recognize that the oscillating motion into reed can be depicted as with simulating.

It addition, " the picking valid period " of the present invention is that the picking about 1 picking amount is according to the pass with the oscillating motion of reed Be the period of conveying effectively being carried out weft yarn by injection water, be by the warp direction from fell side towards fell opposition side The reed allocation position of picking mouth by regulation, and so that the moment of picking can be started as initial point by this picking mouth, with from this The period that moment is terminal that a part for the weft yarn of picking mouth picking initially contacts with reed, in other words, is the swing position of reed It is in the period more sending side than the flight position of the weft yarn on warp thread direction by warp thread.

It addition, the degree in crank angle of picking start time (coordinate of the transverse axis on diagram region 203) i.e. picking starts timing (the degree in crank angle Tjet in Fig. 4) is set in memorizer 102 as weaving condition (picking condition) in the present embodiment.Change Yan Zhi, the picking comprised in picking condition starts timing by as the weft yarn with picking start time comprised in picking mouth information The information that the flight position of W is associated uses.

It addition, the flight position of the weft yarn W about picking finish time, in the present embodiment, by the weft yarn W of 1 picking amount The position (in-position) of front end of the weft yarn W in the moment of picking is finished as picking finish time by each picking mouth N1～N4 The flight position of weft yarn W.

Additionally, as above-mentioned, in the present embodiment, (be the most also referred to as with the weft yarn W by each picking mouth N1～N4 picking " each weft yarn W ".) flight path set the axis phase of each picking mouth N1～N4 towards the mode of the counter substantially co-located sending yarn side Inclination for fell 10.In other words, in the present embodiment, with consistent with the extended line of the axis of each picking mouth N1～N4 The flight path (flight path) of each weft yarn W specific position on woven pieces direction and warp thread direction is intersected, specifically 1 The weft yarn W of picking amount by the moment weft yarn W of picking front end arrive above-mentioned specific position mode set each picking mouth N1～ The axis of N4 is relative to the inclination of fell 10.Therefore, in the present embodiment, the position that the flight path of above-mentioned each weft yarn W intersects The position of the warp thread direction of (in-position of the front end of weft yarn W) is by as each information common for picking mouth N1～N4, i.e. picking The information of the relevant picking finish time comprised in 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 (with The most also referred to as " in-position G ".) mode set picking condition.Therefore, arrival in-position, the front end G's of each weft yarn W is above-mentioned The degree in crank angle of regulation is the degree in crank angle that the flight position of weft yarn W with picking finish time is corresponding.Therefore, in this enforcement In example, the flight position (position of warp thread direction) of the most above-mentioned each weft yarn W, and also the degree in crank angle of this regulation is also by as mouth Timing (the degree in crank angle Tnzl in Fig. 4) and comprising as in the common information of each picking mouth N1～N4, i.e. picking mouth information The information of relevant picking finish time be set.Therefore, as shown in Figure 4, about in-position G, away from the warp thread of fell 10 Distance on direction is distance b, therefore, for the position (coordinate) of the in-position G on diagram region 203, and the seat of transverse axis Mark is represented by mouth timing Tnzl, and the coordinate of the longitudinal axis (away from the distance of fell) is represented by distance b.

Additionally, start timing Tjet about above-mentioned picking, can be by picking mouth the moment of the picking of weft yarn W Degree in crank angle, it is also possible to be the degree in crank angle spraying the moment that water starts injection from picking mouth.That is, knit at general water-jetting type In the picking of machine, start the moment of the picking of weft yarn W prior to picking mouth, start to spray the injection of water, therefore, actually by picking Mouth starts the degree in crank angle in the moment of the picking of weft yarn W and just sprays the degree in crank angle in the moment that water starts from picking mouth to spray Really say not consistent, but the difference of these degree in crank angles is little to ignoring when picking, starts timing accordingly, with respect to picking Tjet, can set any one of these degree in crank angles.

It addition, start timing Tjet about above-mentioned picking, as above-mentioned, if the swing position of reed 9 not ratio weft yarn W Flight path sends the situation of side by warp thread, then can not carry out picking, therefore, from fell 10 towards the reed 9 of going-back position By picking can not be started before carrying out the mouth position of the picking mouth of picking.Therefore, the degree in crank angle in the moment that can carry out picking becomes For reed 9 by the degree in crank angle after the moment of this mouth position.It addition, as above-mentioned, each picking mouth N1, N2, N3, N4 are due to mouth position Put difference, so the degree in crank angle that can carry out picking is different because of each picking mouth, closest to fell 10 picking mouth N4 due to In each picking mouth, reed 9 is the earliest by Qi Zui position, so can carry out picking the earliest in each picking mouth, farthest away from fell 10 Picking mouth N1 owing to, in each picking mouth, reed 9 is the latest by this mouth position, so can throw the latest in each picking mouth Latitude.

On the other hand, for start the relation of the opening amount of timing Tjet and Warp opening 6 with picking, starting picking Moment, the opening amount of Warp opening 6 need for upper warp thread 3a and lower warp thread 3b and injection water interference picking is not caused shadow The size of the degree rung, but, in the mouth position of each picking mouth N1, N2, N3, N4 and the relation side of the opening amount of Warp opening 6 Face, mouth position is closer to fell 10, and the opening amount of Warp opening 6 in the same time is the least, therefore, nearer it is to the picking of fell 10 Mouth, picking starts the most late.Therefore, in the present embodiment, it is considered to the swing position of reed 9 and both opening amounts of Warp opening 6, Start timing Tjet about picking, each picking mouth N1, N2, N3, N4 are set identical degree in crank angle.And, at the present embodiment In, start timing Tjet about this picking, as shown in Figure 4, be set as that postponing, towards finally giving up the throne, the reed 9 moved back from fell 10 passes through It is in the degree in crank angle behind the mouth position of picking mouth N1 away from the farthest position of fell 10.

Additionally, start timing Tjet about this picking, above-mentioned in, be set to reed 9 by according to and the pass of swing position of reed 9 System can carry out the degree in crank angle behind the mouth position of moment of the picking of weft yarn W picking mouth N1 at the latest but it also may it is set to The reed 9 moment (arriving the moment of mouth position) by the mouth position of picking mouth N1.

Specifically, for the picking that picking mouth N1 is carried out, strictly speaking, the weft yarn W's by picking mouth N1 picking Front end arrives the moment of the position sending yarn side of the reed 9 on woven pieces direction, as long as the swing position of reed 9 is positioned at than this weft yarn The front position of W is sent the such picking in side slightly by warp thread and is started timing Tjet, then can carry out picking.And, picking mouth N1 In woven pieces side, the yarn side that send of upward out reed 9 is arranged, at moment of the picking of weft yarn W by picking mouth N1 and weft yarn W Exist with poor between the moment of the position sending yarn side that front end arrives the reed 9 on woven pieces direction.Therefore, even if arriving at reed 9 The moment of the mouth position reaching picking mouth N1 starts the picking of the weft yarn W that picking mouth N1 is carried out, and arrives reed 9 in the front end of weft yarn W Sending the moment of the position of yarn side, the front position that the swing position of reed 9 also is located at than weft yarn W more sends side by warp thread.Therefore, Even if starting picking in the moment of the mouth position that reed 9 arrives picking mouth N1, it is also possible to carried out picking by picking mouth N1, therefore, also The moment of the mouth position that reed 9 can arrive picking mouth N1 starts timing Tjet as picking and is set.

And then, in the present embodiment, by axis to fell 10 roll oblique in the way of be provided with picking mouth N1, therefore, weft yarn W The position of warp thread direction of its front end in moment of the position sending yarn side that arrives reed 9 on woven pieces direction, front end compare picking The mouth position of mouth N1 is more by fell 10 side.Therefore, the picking of weft yarn W can be carried out according to the relation with the swing position of reed 9 Moment in case of the present embodiment for arriving moment a little earlier in moment of the mouth position of picking mouth N1 than reed 9, it is also possible to should Moment starts timing Tjet as picking and is set.But, when the front end of the weft yarn W by picking mouth N1 picking arrives woven pieces side Moment of the position sending yarn side of reed 9 upwards and reed 9 by the difference in the moment of this position too small time, it is possible to cause picking Bad etc., therefore, picking starts the moment that the preferred reed of timing Tjet 9 arrives the mouth position of picking mouth N1.

It addition, about above-mentioned mouth timing Tnzl, as above-mentioned, be that the front end of weft yarn W arrives above-mentioned in-position G (warp thread The flight position of distance b away from fell 10 on direction) the degree in crank angle in moment, but in the present embodiment, with this mouth timing Tnzl and the swing position of reed 9 advanced towards fell 10 from going-back position arrived away from fell 10 apart from moment of the position of b The consistent mode of degree in crank angle set the picking condition of the picking that each picking mouth N1～N4 is carried out.Therefore, at the present embodiment In, the swinging track of reed 9 and the flight path of weft yarn W are interlocked at the in-position G of above-mentioned each weft yarn W, the swinging track of reed 9 To describe in the way of the G of this in-position.

In the water jet loom 1 of above the present embodiment, the initial point of the picking valid period that arithmetical unit 103 is carried out and The acquiring method of terminal and picking valid period is explained in detail below.

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 is carried out is opened Beginning timing Tjet determines by setting, and therefore, the degree in crank angle of the initial point of the picking valid period of each picking mouth N1～N4 is Picking starts timing Tjet.

It addition, about the terminal of picking valid period, the reed 9 advanced towards fell 10 side from going-back position and picking The degree in crank angle in the moment at first that weft yarn W is staggered becomes the terminal of picking valid period.That is, towards the anti-latitude sending yarn side to fly Yarn W is the most staggered with the reed 9 advanced towards fell 10 side, and thus flight speed drastically reduces (or stopping), therefore, The terminal of picking valid period is the degree in crank angle in the moment at first that reed 9 interlocks with weft yarn W.But, in the present embodiment, as Above-mentioned, owing to being inclined relative to fell 10 by the flight path (flight path) of the weft yarn W of each picking mouth N1, N2, N3, N4 picking Tiltedly, thus reed 9 because of the inclination of the fell 10 relative to above-mentioned flight path (flight path) relative to 1 picking amount of picking Weft yarn W part (rearward end) near its front end or picking mouth is interlocked at first.

Specifically, as shown in Figure 4, picking mouth N1, N2 by its axis roll towards fell 10 oblique in the way of arrange, picking The flight path of weft yarn W along with sending yarn side and close to fell 10 from mouth position towards counter.Therefore, picking mouth N1, N2 throw The weft yarn W of latitude is before arrival in-position, front end G (front end interlocks with reed 9), and rearward end is interlocked with reed 9.Additionally, due to this friendship Wrong position near picking mouth N1, N2, so the position on this warp thread direction can with picking mouth N1, N2 to arrange position mutual Changing, the degree in crank angle in this staggered moment becomes degree in crank angle n1, n2 that the mouth position as above-mentioned picking mouth N1, N2 sets.

On the other hand, picking mouth N3, N4 are arranged in the way of its axis tilts towards anti-fell 10 side (side sent by warp thread), The flight path of the weft yarn W of picking is along with sending yarn side to leave relative to fell 10 from mouth position towards counter.Therefore, by picking mouth The front end of the weft yarn W of N3, N4 picking is the most staggered with reed 9 at in-position G.That is, the weft yarn W of picking mouth N3, N4 picking exist Rearward end is interlocked with reed 9 before (the mouth position that reed 9 arrives picking mouth N3, N4), and front end interlocks with reed 9.And, this staggered moment Degree in crank angle become mouth timing Tnzl.

Accordingly, with respect to the terminal of picking valid period, arithmetical unit 103 for each picking mouth N1～N4, by the weft yarn W of picking The degree in crank angle in moment of arrival in-position, front end G, i.e. rear end and the reed 9 of the weft yarn W of mouth timing Tnzl and picking interlock The degree in crank angle in moment, the mouth position that i.e. sets with the degree in crank angle of the present embodiment compares, by less for this angle one Side is set to the terminal of picking valid period.

It addition, arithmetical unit 103 according to the initial point of the most above-mentioned picking valid period obtained and terminal for each picking mouth N1, N2, N3, N4 ask the picking valid period.Additionally, this picking valid period is by deducting the above-mentioned beginning from the degree in crank angle of above-mentioned terminal Point degree in crank angle (picking starts timing Tjet) and ask for, the calculating formula being used for this is stored in arithmetical unit 103.Each picking mouth The calculating of the picking valid period of N1, N2, N3, N4 is specific as follows.

About picking mouth N1, as above-mentioned, hand over reed 9 with the degree in crank angle in moment the earliest for the rear end of the weft yarn W of picking Mistake, so the degree in crank angle n1 set as mouth position becomes the terminal of picking valid period.Therefore, the picking of picking mouth N1 has Effect period c1 is calculated by following calculating formula.

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

Equally, about picking mouth N2, the degree in crank angle n2 set as mouth position also becomes the terminal of picking valid period, The picking valid period c2 of picking mouth N2 is calculated by following calculating formula.

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

It addition, about picking mouth N3, as above-mentioned, owing to the front end of weft yarn W of picking is with the degree in crank angle in moment at first Interlock, so the degree in crank angle corresponding with above-mentioned in-position G i.e. mouth timing Tnzl becomes the picking valid period with reed 9 Terminal.Therefore, the picking valid period c3 of picking mouth N3 is calculated by following calculating formula.

The c3=mouth timing Tnzl-picking of picking valid period starts timing Tjet

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

The c4=mouth timing Tnzl-picking of picking valid period starts timing Tjet

Secondly, the effect to the picking information display device 100 in the present embodiment structure illustrates.Operator is with basis Initial setting sets the state of picking condition to carry out examination and spins, and result is, is being judged as the situation that needs to be adjusted picking Under Deng, operator uses picking information display device 100, is confirmed each picking mouth under initial setting state by display 106 The picking valid period, seek adjustment amount.

The picking valid period under the state that operator confirms this initial setting to set the standard of above-mentioned adjustment amount, First the aforesaid operations button of the loader 101 of operation picking information display device 100.Thus, at picking information display device In 100, from loader 101 to output display command signal arithmetical unit 103 of display arithmetic unit 107.

Arithmetical unit 103 when inputting above-mentioned idsplay order signal, as initial point and end for asking the picking valid period The information of the value of point and this picking valid period, reads picking mouth information from memorizer 102, asks the picking of each picking mouth N1～N4 The initial point of valid period and terminal, and seek picking valid period c1～c4, and by the throwing of this each picking mouth N1～N4 obtained The initial point of latitude valid period, terminal and picking valid period c1～c4 export to display controller 105.

Display controller 105 inputs the picking valid period of above-mentioned each picking mouth N1～N4 obtained from arithmetical unit 103 When initial point, terminal and each picking valid period c1～c4, as it is shown in figure 5, by the picking of above-mentioned each picking mouth N1～N4 obtained The initial point of valid period, terminal and each picking valid period c1～c4 display 106 display picture 200 on be located at figure The hurdle of the regulation solving the display field 201 on the right side in region 203 shows.

It addition, display controller 105 reads picking mouth information from memorizer 102, and based on this picking mouth information in display Describe and show the flight path of weft yarn W on diagram region 203 on picture 200, and using the swinging track of reed 9 as passing By the crossover location of the flight path of weft yarn W and mouth timing Tnzl being configured at picking mouth N1 picking by fell opposition side The curve of arc-shaped describes display on above-mentioned diagram region 203.Additionally, the flight path of weft yarn W and the swinging track of reed 9 Plotting method Details as Follows.

As above-mentioned, in the present embodiment, retouch based on the information relevant to 2 flight positions on the flight path of weft yarn W Paint the flight path of weft yarn W, therefore, in picking mouth information, as the information relevant to picking start time, for each weft yarn The initial point of the flight path (flight path) of W set the flight position of the weft yarn W as picking start time each picking mouth N1, The mouth position of N2, N3, N4.

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

Therefore, according to mouth position (distance a1 away from fell 10, a2, a3, a4) and the work of this each picking mouth N1, N2, N3, N4 The picking being set in memorizer 102 for above-mentioned weaving condition (picking condition) starts timing Tjet (crank when picking starts Angle), the coordinate of the initial point of the above-mentioned flight path on specific above-mentioned diagram region 203.

It addition, as above-mentioned, in picking mouth information, as the information about picking finish time, for flying of each weft yarn W The terminal in walking along the street footpath (flight path) is set with the flight position i.e. arrival of the front end of weft yarn W of the weft yarn W of picking finish time Position G (position of distance b away from fell 10) and the mouth timing Tnzl of the degree in crank angle as this moment, above-mentioned diagram region The coordinate of the terminal of the above-mentioned flight path on 203 is specific according to these information.Therefore, display controller 105 is based on according to throwing Latitude mouth information and picking start initial point and the coordinate of terminal of the above-mentioned flight path that timing Tjet obtains, as through this 2 point Straight line diagram region 203 on display picture 200 on describe the flight path of each weft yarn W.

About the swinging track of reed 9, in the present embodiment, as above-mentioned, describe the circular arc of the oscillating motion of analog representation reed 9 The curve of shape, the curve of this arc-shaped is described as follows, i.e. with above-mentioned beating point (point of the distance 0 away from fell 10) as initial point (0 °) and terminal (360 °), at least across the swinging track of reed 9 with by being configured at picking mouth N1 picking by fell opposition side Crossover location (distance b) away from fell 10 and the anglec of rotation (mouth of main shaft 12 in moment of intersecting thereof of flight path of weft yarn W Timing Tnzl) point (in-position G) that determines.

Additionally, using the swinging track of reed 9 as arc-shaped curve describe reason be because in general loom, Reed 9 is supported by rocker, this rocker by with spindle motor M be drive source crank mechanism reciprocating rotary drive, so, because of with The relation of crank-motion and the top dead-centre of such as crank-motion and bottom dead centre and the swing of reed 9 limit (progressive position and retreating most Position) in the case of consistent structure, the oscillating motion of reed 9 describes sine curve with the relation with degree in crank angle.Therefore, with Transverse axis is degree in crank angle and to describe swing position (the warp thread side of reed 9 on diagram region 203 that the longitudinal axis is distance away from fell 10 The upwards distance away from fell 10) loom 1 cycle in change in the case of, this track is retouched by the curve as arc-shaped Paint.

But, the swinging track of reed 9 is not necessarily limited to the curve of the arc-shaped of sine due to the structure of crank mechanism, separately Outward, in the present invention, if the swinging track of reed 9 is the most correctly described the flight path of weft yarn W and carries out the reed 9 of oscillating motion Relevant part (staggered moment), then for comprising the other parts of above-mentioned beating point, as long as can show reed 9 relative 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 configured at By fell opposition side picking mouth N1 staggered point actual with reed 9, i.e. the in-position G of the weft yarn W of the present embodiment (sit by transverse axis Mark: mouth timing Tnzl/ ordinate of orthogonal axes: b), and comprise its outer part of above-mentioned beating point by as the pendulum with actual reed 9 The curve of the arc-shaped of the simulation that dynamic track is different is described.And, as it is shown in figure 5, display controller 105 is by this reed 9 Swinging track display picture 200 on diagram region 203 on describe.

Additionally, about the swinging track of this reed 9, as above-mentioned, in the present embodiment, set owing to picking starts timing Tjet It is set to the degree in crank angle after reed 9 has passed through the mouth position of picking mouth N1, so the flight path of the weft yarn W by picking mouth N1 picking Only interlock at above-mentioned in-position G with the swinging track of reed 9, but be set as that reed 9 arrives throwing picking being started timing Tjet In the case of the moment of the mouth position of latitude mouth N1, in display, the swinging track of reed 9 and by the weft yarn W's of picking mouth N1 picking Flight path is also carried out interlocking at picking starting position (transverse axis coordinate: picking starts timing Tjet/ ordinate of orthogonal axes: a1).Therefore, In the case of Gai, the swinging track of reed 9 be described in the way of also through the coordinate of picking starting position.It addition, such as the present embodiment, reed The swinging track of 9 is not limited to simulation and describes, it is also possible to obtain based on the swing position of degree in crank angle and reed 9 being set explicitly Reed swing information describe as the information consistent with the oscillating motion of actual reed 9.

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

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

It addition, in the case of picking mouth N3, N4, as above-mentioned, due to for common mouth timing Tnzl (in-position G), So as it is shown in figure 5, the position of the degree in crank angle being equivalent to mouth timing Tnzl on the transverse axis in diagram region 203, describe with The line chart (ordinate) that the longitudinal axis is parallel, and show with mark " Tnzl " in this position.And, same as described above, at display field 201, this degree in crank angle (in example illustrated being 280 °) is shown on the hurdle being designated as " mouth timing Tnzl ".So, picking The terminal of valid period is showing on picture 200 also will appreciate that the form of its degree in crank angle shows.

It addition, each picking valid period c1～c4 is from above-mentioned initial point to the period of above-mentioned terminal, as it is shown in figure 5, at figure Solve and state, for stepping up, the line chart being depicted as between the ordinate of initial point and the above-mentioned ordinate being depicted as terminal, to each throwing on region 203 Latitude mouth describes the line chart (horizontal line) parallel with the transverse axis that two ends are set to arrow.It addition, it is aobvious above each line chart of this description Show and represent the mark " c1 " of picking valid period of correspondence, " c2 ", " c3 ", " c4 " respectively.And, in the present embodiment, upper The display field 201 stated, would indicate that each picking valid period crank angle (in example illustrated be respectively 165 °, 175 °, 180 °, 180 °) being designated as " picking valid period " " c1 ", " c2 ", " c3 ", the hurdle of " c4 " shows.

Additionally, as it has been described above, in the present embodiment, in the diagram of the swinging track of the flight path and reed 9 showing weft yarn W The initial point of picking valid period and terminal and each picking valid period c1～c4, their degree in crank angle is shown on region 203 Can grasp on picture 200, but in the present invention, the initial point of the picking valid period in them and each picking valid period c1 ～c4 is not necessarily required to show.

This is because, the initial point of picking valid period is the most above-mentioned starts timing for each picking common for picking mouth N1～N4 Tjet, this is set by operator, therefore, instead do not show, and is grasped by operator self.It addition, picking Valid period starts timing Tjet by deducting above-mentioned picking from the degree in crank angle of the terminal of picking valid period and obtains, i.e. Make not show, as long as will appreciate that the terminal of picking valid period, it is possible to easily obtain from there through simple calculating.

But, for the terminal of picking valid period, operator is in order to grasp it, it is often necessary to use stroboscope Confirming Deng in actual picking, this grasp operation is the most numerous and diverse.Therefore, in the present invention, for this picking effect duration Between terminal, the picture 200 of display 106 will appreciate that its degree in crank angle.

So, as it is shown in figure 5, show the expression flight path of weft yarn W, reed on the diagram region 203 of display picture 200 Swinging track, the initial point of the picking valid period i.e. picking of 9 start the line chart of timing Tjet and represent the end of picking valid period Point i.e. degree in crank angle n1, n2 and the line chart of mouth timing Tnzl.It addition, at the display field 201 of display picture 200, with degree in crank angle Display picking valid period c1, c2, c3, c4, and show that above-mentioned picking starts timing Tjet and the crank of mouth timing Tnzl Angle and degree in crank angle n1, n2, n3, n4 of setting as mouth position.

Therefore, in the present embodiment, operator is by observing diagram region 203 shown on above-mentioned display picture 200 And display field 201 will appreciate that initial point and the degree in crank angle of terminal, the value of picking valid period (length) of picking valid period.

As above, the display that operator first passes through from display picture 200 in picking adjusts confirms initial setting state Picking valid period c1～c4 of each picking mouth N1～N4 grasp present situation.And, operator's setting item to needing adjustment Mesh, value n1 of mouth position of the most each picking mouth N1～N4～n4 or picking start whether the setting etc. of timing Tjet there is a need to adjust Whole arbitrary project is inquired into, and uses loader 101 to carry out the setting value that change should become the setting item of regulating object Operation.

And, by this operation, setting of the setting item becoming above-mentioned regulating object that renewal is stored in memorizer 102 Definite value.Then, when operator operates the operation button of loader 101 again, picking information display device 100 by with above-mentioned phase Same order utilizes picking valid period c1～c4 after asking the change of above-mentioned setting value arithmetical unit 103, and utilizes display control Flight path and the swinging track of reed 9 of weft yarn W described on diagram region 203 by device 105, and then describes to represent picking effect duration Between initial point and terminal and the line chart of picking valid period, and the display field 201 on display picture 200 shows each song Handle angle.

Its result, operator can confirm the picking effect duration after above-mentioned setting change by the display of display 106 Between c1～c4.And, judging that picking valid period c1～c4 of setting value changed in the result according to this confirmation is suitable In the case of carrying out picking, carry out the adjustment of reality based on this setting value, and carried out, after the test weaving of confirmation, starting to knit Make.It addition, in the result of the display by confirming display 106, it is judged that for effective in the picking according to the setting value after change In the case of period c1～c4 suitably can not carry out picking, the corresponding setting item adjusted and setting value thereof are inquired into again, On picking information display device 100, the setting item and setting value thereof reflecting this discussion result is carried out a series of operation, by This flight path that can reaffirm 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, one embodiment of the invention is illustrated, but the invention is not restricted to above-described embodiment, it is also possible to as Following variation is implemented.

In the above-described embodiments, illustrate the water jet loom application present invention's possessing 4 picking mouth N1～N4 The example of the display of picking information, but the water jet loom of the application present invention is not limited to such loom, it is also possible to it is applicable to Possesses the water jet loom of multiple picking mouths of less than 3 or more than 5.It addition, be not limited to possess knitting of multiple picking mouth Machine, it is also possible to be applicable to the water jet loom only possessing 1 picking mouth.Additionally, in the case of picking mouth is only 1, this 1 picking mouth of " being configured at the picking mouth by fell opposition side " of invention is equivalent to this 1 picking mouth.

It addition, in the above-described embodiments, water jet loom is possessed to the feelings of multiple picking mouth (picking mouth N1～N4) Condition, starts timing Tjet by the picking of each picking mouth and is set as identical degree in crank angle, and, by the initial point of picking valid period The picking being fixed on this setting starts timing Tjet.But, it is not limited to this in the present invention, sprays at the water possessing multiple picking mouth Penetrate in formula loom, it is also possible to the picking of the picking mouth of more than 1 is started timing Tjet and sets in the early stage or in adjustment afterwards It is set as starting the different degree in crank angle of timing Tjet from the picking of other picking mouth.It addition, in the case of Gai, it is also possible to according to throwing Latitude mouth information (flight path of weft yarn) and reed swing information (swinging track of reed) ask the beginning of picking valid period to be asked for Point.

Specifically, as above-mentioned, can carry out picking time be engraved in each picking mouth as from fell 10 (progressive position) court The reed 9 moved back is postponed by the degree in crank angle after the moment of the mouth position corresponding with this picking mouth to finally giving up the throne.Such as exist In the case of above-described embodiment, if accounted on the basis of the picking of picking mouth N1 starts timing Tjet, then with reference to The picking postponing the moment reed 9 picking mouth N1 setting picking mouth N2～N4 by mouth position starts timing Tjet, but for picking Mouth N2～N4, according to the relation with the swing position of reed, can when the picking than picking mouth N1 start timing Tjet Zao when Start picking.

On the other hand, timing Tjet is started about picking, it is also necessary to the relation of opening amount with Warp opening 6 will be considered, Due to be positioned at than picking mouth N1 more by picking mouth N2～N4 of fell side in the opening amount of Warp opening 6 position less than picking mouth N1 Put and carry out picking, so according to the relation with this opening amount, the most sometimes the picking of picking mouth N2～N4 being started timing Tjet and set It is set to the picking than picking mouth N1 and starts the timing Tjet slow moment.So, in water jet loom, it is not limited to multiple throwings The picking of latitude mouth starts timing Tjet and is set as identical timing (degree in crank angle) regularly, also sometimes according to set weaving Each picking mouth is set by the kind etc. of the weft yarn of condition and picking with different timings.And, before weaving starts Metamorphosis stage, this picking sometimes starts timing also can become regulating object.

In the case of Gai, about the initial point of picking valid period, it is also possible to same as the previously described embodiments is set picking Start timing Tjet, but this picking start the setting of timing Tjet along with adjusting in the case of, in order to set this adjustment Standard, this initial point can also be obtained based on picking mouth information (mouth position) and reed swing information (swing position of reed).Additionally, should In the case of, the terminal obtained in initial point that the picking valid period is obtained according to this and above-described embodiment calculates.It addition, as above-mentioned, In order to be set to the standard that picking starts the adjustment of timing Tjet, and ask for picking according to picking mouth information and reed swing information and have In the case of initial point during effect, the not only terminal of picking valid period, the initial point of the picking valid period that at least this is obtained, also Preferably enterprising in the diagram region 203 of the display picture 200 of picking information display device 100 so that the form of degree in crank angle can be grasped Row display.

Additionally, the present invention is also not limited to any embodiment described above, without departing from spirit of the invention, just Various change can be carried out.
