The Weft-insertion-condition display method of loom

Technical field

The present invention relates in having the loom of display unit, according to the easy display packing of the differentiation that makes its reason unusually of statistical value, this display unit is the diagram demonstration statistical value relevant with Weft-insertion-condition on time shaft.

Background technology

The open 2006-9233 communique of Japan Patent discloses a kind of Weft-insertion-condition display unit of loom, and its formation is to show the relevant statistical value of guiding latitude situation as the time series diagram on time shaft.Technology according to above-mentioned patent documentation, in the predetermined sampling time, the statistical value of the arrival angle of the weft yarn during to wefting insertion, can by diagram show visual recognition its through the time variation, whether can confirm between each sampling period in the arrival angle generation deviation of weft yarn etc. unusual according to the variation of statistical value.And above-mentioned patent documentation also records the content that will determine unusual former of wefting insertion thereby show the situation occurred that wefting insertion is bad at identical time shaft except above-mentioned demonstration.But weak point is: the technology of above-mentioned patent documentation is about the demonstration relevant with the bad situation occurred of its wefting insertion, shows the technology of the degree whether bad and kind that wefting insertion is bad of wefting insertion has taken place between each sampling period.

But, in above-mentioned diagram result displayed, when the statistical value of the arrival angle of weft yarn notes abnormalities, preferred early stage its reason of determining.For example, its reason is during based on unusual etc. the basic reason of employed weft yarn (for the yarn body) or weft inserting apparatus, because therefore identical situation repeatedly not, needs early time treatment.Thereby, taking place when unusual at statistical value as above-mentioned, hope can be differentiated its reason easily.

In addition, above-mentioned statistical value unusually to be boundary when continuing to take place sometime in weaving, can differentiate for its reason based on as above-mentioned basic reason.But, above-mentioned statistical value be not continue to take place and when temporarily taking place, consider various reasons, so the differentiation difficulty of its reason unusually.But even the unusual of above-mentioned statistical value is temporary transient, also its reason is unusual for the unusual or weft inserting apparatus of yarn body probably, so also need the differentiation of reason this moment.

But, in the display unit of the past technology of the open 2006-9233 communique of Japan Patent, but be to show that whether wefting insertion to have taken place bad, so in the content of this degree shows, can not differentiate in the unusual reason of above-mentioned statistical value appearance, be used for differentiating its reason as its result and can need the time.

Summary of the invention

The present invention has overcome deficiency of the prior art, a kind of Weft-insertion-condition display method of loom is provided, on possessing time shaft, in the display unit of the Presentation Function of the size of the diagram demonstration statistical value relevant with the Weft-insertion-condition of loom, when noting abnormalities, above-mentioned statistical value make the differentiation of its reason easy.

For solving the problems of the technologies described above, the present invention is achieved by the following technical solutions: show the information relevant with the main cause of the flight change that makes weft yarn at the picture identical with the display frame of the statistical value in arrival period of relevant weft yarn.If record particularly, the Weft-insertion-condition display method of loom involved in the present invention then, in possessing the loom of display unit, this display unit is calculated the statistical value relevant with above-mentioned arrival period between each predetermined sampling period period based on the arrival of the detected weft yarn of each wefting insertion, woven above-mentioned statistical value through calculating is successively followed in sequence storage on time, and in the size that shows this stored above-mentioned statistical value on the time shaft through the diagram of time ground, above-mentioned Weft-insertion-condition display method shows the information relevant with the main cause of the flight change that makes weft yarn at the picture identical with the display frame of above-mentioned statistical value.

Above-mentioned " making the main cause of the flight change of weft yarn " refers to become the reason of flight (flying speed, the state of flight etc.) change of the weft yarn in the opening that makes warp thread, in other words, can become the reason of the arrival change in period of the weft yarn that the flight that is subjected to weft yarn influences.And, on identical picture, about the information that should " make the main cause of the flight change of weft yarn " and relevant the demonstration towards the diagram for the statistical value in arrival period of the weft yarn of yarn opposition side are presented on the time shaft together.For example can enumerate (1) information relevant with the switching that supplies the yarn body as this information; (2) with the relevant information that resets of wefting insertion condition (especially, wefting insertion begin regularly etc.); And (3) above-mentioned (1) and (2) information in addition and the information relevant with the change of the weaving condition of the main cause that can become the flight change that makes weft yarn (for example, the revolution of wefting insertion pattern, Warp opening pattern, weft count, loom etc.).

(1) with for the relevant information of the switching of yarn body refers to the detection information relevant with the switching instant for the yarn body of the weft yarn that is detected by sensor.In more detail, set up in the loom of sensor of yarn cylinder sensor or tieing sensor etc. at Yarn supply device, in weaving, it is following or do not have to become predefined scheduled volume for the residual yarn amount of yarn body, in the moment that arrives the period that is replaced for the yarn body, detect this situation by the sensor.Saidly be and detected the relevant information of this moment that is replaced for the yarn body that becomes by the sensor for the relevant information of the switching of yarn body with above-mentioned.

(2) information relevant with resetting of wefting insertion condition refers to return the relevant information of the reset operation of initial value with the wefting insertion condition that makes change in loom, and above-mentioned loom is carried out the wefting insertion control according to the arrival angle change wefting insertion condition of weft yarn.

That is, in loom, extensively adopt based on the automatic control being changed the wefting insertion condition by the arrival angle of the weft yarn of the detected reality of purpose of certainization of arrival angle of the weft yarn of wefting insertion.On the other hand, the arrival angle of weft yarn also changes according to the variation (minimizing) of following the woven winding diameter that supplies the yarn body that carries out.Therefore, be a timing making the wefting insertion condition, especially, even in not variations such as weft inserting apparatuss, the arrival angle is followed woven carrying out and is changed successively.Thereby in possessing the loom of above-mentioned automatic control, by following the minimizing of the woven winding diameter that supplies the yarn body that carries out, the wefting insertion condition is changed successively.And, when following replacings such as supplying exhausting of yarn body for the yarn body, as the above-mentioned reset operation that carries out the wefting insertion condition that changes according to the minimizing of the winding diameter that supplies the yarn body is returned initial value.And the information relevant with resetting of above-mentioned wefting insertion condition refers to represent to carry out the information of reset operation of the automatic control of this wefting insertion.

Explanation in passing, for example can enumerate as above-mentioned wefting insertion condition: the beginning of wefting insertion regularly, that is, wefting insertion regularly (if possess the loom of auxiliary main burner, comprise that also the injection beginning of auxiliary main burner regularly) with the injection beginning of main burner and/or the length measuring weft storing device in the alleviating regularly of card shotpin.And, in addition, also comprise the expulsion pressure of above-mentioned main burner (auxiliary main burner) or spray stop timing, wefting insertion with expulsion pressure or the injection beginning/stop timing of auxiliary jet (auxiliary jet of each group).In addition, if possess the loom of weft brake, the wefting insertion condition also comprises the action timing of weft brake.

In addition, as above-mentioned, the reset operation of wefting insertion condition is followed for the switching of yarn body and is carried out.Thereby, also we can say the information that belongs to relevant with the switching for the yarn body of above-mentioned (1) with the relevant information that resets of the wefting insertion condition of (2).

(3) information relevant with the change of weaving condition refers to above-mentioned (1) and (2) information in addition, represents that this change can become the information that the weaving condition of the main cause of the flight change that makes weft yarn has been changed.For example can enumerate the condition relevant with the weaving modes such as revolution of weft count, Warp opening pattern, loom as this weaving condition.And in addition, the wefting insertion pattern is changed weaving in the way of identical fabric sometimes, and this wefting insertion pattern is also included within above-mentioned weaving condition.

Explanation in passing, change to above-mentioned wefting insertion pattern (wefting insertion order) refers in the multicolor weft insertion loom, particularly in the way of weaving identical fabric, sometimes replace each weft yarn and the weft insertion system corresponding relation of (comprising main burner, length measuring weft storing device) as required, change the wefting insertion pattern thereupon.For example, the weft yarn to C1 carries out following replacement sometimes, namely, to supply with and the weft yarn of main burner wefting insertion by No.1 from the storage Weft handling device of No.1, supply with and main burner wefting insertion by No.2 from the storage Weft handling device of No.2, at this moment, also change the wefting insertion pattern of setting as the action of weft insertion system.At this moment, in the air injection type loom, main burner No.1, No.2 arrange the position difference, and the flight position of the weft yarn in the weft guide groove of reed changes, and therefore, the replacing of wefting insertion pattern also becomes the main cause of bringing influence to the flight of weft yarn.

And, about the change of the weaving states such as revolution of Warp opening pattern, weft count, loom, for example, when knitting from the looped pile tatting of terry cloth loom, automatically carry out based on predefined weaving-pattern basically with changing to.But, in fact less carry out, but also consider in weaving situation by operating personnel's change, also comprise the information of this moment as the information relevant with the change of above-mentioned weaving condition.

And, above-mentioned " showing at identical picture " comprising: relevantly show towards the diagram for the statistical value of the arrival angle of the weft yarn of yarn opposition side (below, be also referred to as " statistical value demonstration ") display frame on the overlapping demonstration information relevant with the main cause of the flight change that makes above-mentioned weft yarn (below, be also referred to as " change main cause information ") demonstration display frame or arrange the display frame of the demonstration that shows display frame that statistical value shows and change main cause information at the picture of display unit.And, be also included within the display mode that comprises the statistical value demonstration in the demonstration and change the demonstration of main cause information.

Compared with prior art, the invention has the beneficial effects as follows: according to the present invention, except arrival period of the demonstration of sequence diagram on time on the time shaft and weft yarn relevant statistical value, show the relevant information of main cause that changes with the flight that makes above-mentioned weft yarn at this identical picture.Thereby, when statistical value unusual confirmed in identical display frame, can differentiate its reason easily and whether cause by becoming the above-mentioned information that shows object.

Particularly, sometime, be that the boundary continues to occur when unusual at the statistical value relevant with arrival period of weft yarn constantly temporarily or with this, its reason is not limited to 1, considers various reasons.As in the record of the hurdle of background technology, preferably differentiate its reason in early days, but all main causes that can expect are confirmed one by one, so need time and time.

To this, according to the present invention, in the moment that is identified unusually of statistical value, can confirm easily on the picture of display unit near whether carry out bringing influence to the flight of weft yarn its unusual generation change, especially resetting or the change of weaving condition etc. for the switching of yarn body, wefting insertion condition.Thus, can judge that whether unusual reason occurs at statistical value is caused by these changes, can carry out the differentiation of reason easily in shorter time.

Especially, has the tendency of the flight change of weft yarn for the switching of yarn body the time or during the resetting of wefting insertion condition (wefting insertion begins regularly), but but the diagram of the change reason of time series contrast this moment and the statistical value relevant with arrival period shows on time shaft, owing to can visually read both corresponding relations, can determine causality easily.

The specific embodiment

Fig. 1 is as being suitable for the major part that fluid jet type weaving machine of the present invention illustrates the air injection type loom.Illustrated air injection type loom possesses the weft inserting apparatus 1 of 2 looks as an example.In the weft inserting apparatus 1 of Fig. 1, the weft yarn 4 of color C1, C2 is from being drawn out for yarn body 3 of being supported by support 2, for example be directed to the inside of rotation yarn introduction member 6 of the length measuring weft storing device 5 of drum, outer peripheral face at the drum barrel 7 of inactive state is ended by card shotpin 8 cards, and is wrapped in the outer peripheral face of drum barrel 7 by rotatablely moving of yarn introduction member 6 of rotation.Thus, the weft yarn 4 of the length that 1 wefting insertion is required is wrapped in the outer peripheral face of drum barrel 7, and the storage latitude is during to the wefting insertion of weft yarn 4.

The main burner 10 that length measuring weft storing device 5 (the advance and retreat motion that rotatablely moves and block shotpin 8 of rotation yarn introduction member 6) or wefting insertion described later are used moves based on the selecting sequence of weft yarn 4 by the wefting insertion control part 31 of the inside of control device 20.In addition, yarn cylinder sensor 39 is arranged on near the yarn body 3, and detecting the corresponding residual yarn amount for the weft yarn 4 in the yarn body 3 becomes below the scheduled volume, and detection signal S4 takes place this moment.

Begin regularly at wefting insertion, the card shotpin 8 corresponding with the weft yarn selected by wefting insertion control part 31 4 driven by operator 9, if retreat from the outer peripheral face of drum barrel 7, the weft yarn 4 that then is wound on the required length of 1 wefting insertion of periphery of drum barrel 7 becomes the state that can alleviate at drum barrel 7.And the main burner of using by wefting insertion 10 carries out injection action, and the weft yarn 4 that leads to main burner 10 alleviates and by wefting insertion from drum barrel 7.In addition, in this example, main burner 10 constitutes as 2 structures that connect formula at the auxiliary main burner 10a of direction arranged in series and the main main burner 10b of weft yarn 4.

The timing that begins at the wefting insertion that is set corresponding to the main burner 10 of selecteed weft yarn 4 is towards the injection of the opening 14 initiation pressure air 12 of warp thread 13, spray by continuing between the injection period that continues to be set, with weft yarn 4 wefting insertion of predetermined length in opening 14.By this wefting insertion action, weft yarn 4 flies along the weft yarn flight path in the opening 14.In addition, pressure air 12 is set for after the suitable force value of wefting insertion by common pressure-regulating valve 27 from pressure air source 26, and each electromagnetic opening and closing valve 28 of process supplies to auxiliary main burner 10a and the main main burner 10b as main burner 10.Each electromagnetic opening and closing valve 28 moves based on the weft yarn selecting sequence by the control of wefting insertion control part 31.

As above-mentioned, the weft inserting apparatus 1 of Fig. 1 is 2 look wefting insertion, but during the multicolor weft insertion more than 2 looks, arranges according to the polychrome number for yarn body 3, length measuring weft storing device 5 and main burner 10, presses the weft yarn selecting sequence by wefting insertion.Certainly, if 1 look wefting insertion is then only established 1 length measuring weft storing device 5 and main burner 10.

In the process of being flown along the flight path in the opening 14 by the weft yarn 4 of wefting insertion, a plurality of groups auxiliary jet 11 sprays pressure air 15 at weft yarn flight path relaying when the heading of weft yarn 4 sprays simultaneously or pressure air 15 and the flying speed of weft yarn 4 coordinated, thereby in opening 14 aloft weft yarn 4 is leaned on partially towards the wefting insertion direction.In addition, pressure air 15 is supplied to from pressure air source 26, sets suitable force value supplies to each group afterwards through the electromagnetic opening and closing valve 30 of each group auxiliary jet 11 for by pressure-regulating valve 29.The electromagnetic opening and closing valve 30 of each group is in when wefting insertion under the control of wefting insertion control part 31, sprays simultaneously or the relaying injection at a plurality of groups auxiliary jets 11, and aloft weft yarn 4 is leaned on partially towards the wefting insertion direction.

The injection action of the auxiliary jet 11 by main burner 10 and a plurality of groups, weft yarn 4 is during normally by wefting insertion, this weft yarn 4 is beaten at 17 the fell 18 of weaving cotton cloth by the beating motion of reed 16, weave cotton cloth after 17 inweaving,, disconnect from the weft yarn 4 of the inside of main main burner 10b by cutting off for yarn scissors 19 in the wefting insertion side.

Whether normally carried out wefting insertion, detected by the 1st bobbin feeler 21 and this sensor 24, the 2nd bobbin feeler 22 and this sensor 25.The sensor 24 of the 1st bobbin feeler 21 is relative with the weft yarn flight path near 17 the selvedge part of weaving cotton cloth of wefting insertion opposition side, be arranged on normally by weft yarn 4 accessible positions of wefting insertion, at this sensing normally by the front end of the weft yarn 4 of wefting insertion.This sensing is undertaken by the level and the baseline signal level that compare the sensing signal that takes place at sensor 24 in the normal arrival period of weft yarn 4 (during the sensing of setting).Thereby, according to the sensor 24 of the 1st bobbin feeler 21, with the wefting insertion of the position of the front end no show sensor 24 that is irrespectively detected weft yarn 4 by wefting insertion bad (short latitude, curved latitude etc.).In addition, set in the anglec of rotation of main shaft 33 usually during the sensing.

During above-mentioned sensing, when sensor 24 detects the arrival of weft yarn 4, the output signal corresponding to this takes place.At this moment, the yarn signal S1 corresponding to normal wefting insertion takes place based on the output signal from sensor 24 in the 1st bobbin feeler 21, and master control part 36 and the statistical value of this yarn signal S1 being delivered to the inside of control device 20 calculate means 40.Master control part 36 continues the running (weaving) of loom with the condition that exists for corresponding to the yarn signal S1 of normal wefting insertion.In addition, statistical value calculates means 40 and constitutes statistical value calculating part 38 with computing means 54, as described later in detail, and in order to show Weft-insertion-condition, between each predetermined sampling period, calculate the statistical value relevant with the arrival period (arrival angle) of weft yarn 4 according to yarn signal S1.

During above-mentioned sensing, when yarn signal S1 did not take place, it is bad that wefting insertion namely takes place, when sensor 24 fails to detect the arrival of weft yarn 4, it is unusual that the 1st bobbin feeler 21 is judged as wefting insertion, and output stops latitude signal S2, this is stopped latitude signal S2 deliver to master control part 36 and computing means 54.

Stop latitude signal S2 if master control part 36 receives, then execution stops control immediately, stops loom in predetermined angle.Stopping of the loom of this moment is the parking that the wefting insertion by weft yarn 4 causes unusually, is equivalent to the demonstration " weft yarn parking " among Fig. 3 described later and Fig. 4.And as described later in detail, but computing means 54 are presented at the parking condition of the loom that takes place between predetermined sampling period for the state with visual recognition, and integrating is by the 1st bobbin feeler 21 detected stop frequencies that caused unusually by the wefting insertion of weft yarn 4.

And, at the wefting insertion opposition side, the sensor 25 of the 2nd bobbin feeler 22 is further namely normally relative with the weft yarn flight path by the position of weft yarn 4 no shows of wefting insertion towards the position that the wefting insertion direction is left at ratio sensor 24 with respect to 17 the selvedge part of weaving cotton cloth, for blowing of sensing weft yarn 4 break or the wefting insertion of long latitude bad and arrange.During sensing, carry out this sensing by comparison at the level of the sensing signal of (arrival angle) sensor 25 generations in the unusual arrival period of weft yarn 4 and the level of reference signal.In addition, set in the anglec of rotation of main shaft 33 usually during the sensing.During this sensing, when the 2nd bobbin feeler 22 is imported from the output signal of sensor 25, be judged as the unusual of wefting insertion, stop latitude signal S3, this is stopped latitude signal S3 deliver to master control part 36 and computing means 54.

Master control part 36 similarly, stops loom in predetermined angle if reception stops latitude signal S3 when then stopping latitude signal S2 with reception immediately.Stopping of the loom of this moment also is the parking that causes unusually by weft yarn 4, is equivalent to the demonstration " weft yarn parking " among Fig. 3 described later and Fig. 4.And as described later in detail, but computing means 54 are presented at the parking condition of the loom that takes place between predetermined sampling period for the state with visual recognition, and integrating is by the 2nd bobbin feeler 22 detected stop frequencies that caused unusually by the wefting insertion of weft yarn 4.

The computing means 54 of statistical value calculating part 38 except integrating respectively by the detected stop frequency that is caused unusually by the wefting insertion of weft yarn 4 of the 1st bobbin feeler 21 with by the detected stop frequency that is caused unusually by the wefting insertion of weft yarn 4 of the 2nd bobbin feeler 22, both sums of integrating as required.

In addition, the broken end of warp thread 13 detects by menopause tablet device 50, and the unusual selvage devices 52 by two selvedges such as broken end that the lace stitch of selvedge forms the limit yarn 51 of usefulness detect.Menopause tablet device 50 has not shown menopause tablet according to the bar number of warp thread 13, and each warp thread 13 is made as the state of hanging by corresponding menopause tablet with menopause tablet, and each menopause tablet is remained on predetermined height.And selvage device 52 is by applying the lace stitch that is twined to be formed for to keep the end of weft yarn 4 to a plurality of limits yarn 51 when per 1 wefting insertion.

In weaving, if break end at any warp thread 13, the menopause tablet of position of then breaking end drops, between the menopause tablet that drops and not shown electrode, form the closed circuit of electricity, therefore, menopause tablet device 50 drops from the "on" position sensing menopause tablet of closed circuit, and menelipsis signal S10 takes place, and this is delivered to master control part 36 and computing means 54.

And, in weaving, if cause broken end at limit yarn 51, then be arranged on the broken end of not shown yarn sensor sensing limit, the limit yarn 51 in the selvage device 52, menelipsis signal S11 takes place, this is delivered to master control part 36 and computing means 54.

When master control part 36 receives menelipsis signal S10 or menelipsis signal S11, same during with weft yarn 4 unusual, loom is stopped immediately in predetermined angle.It is the parking that causes unusually by warp thread 13 or limit yarn 51 that the loom of this moment stops, and is equivalent to the demonstration " warp thread parking " among Fig. 3 described later and Fig. 4.And, as described later in detail, but computing means 54 are presented at the parking condition of the loom that takes place between predetermined sampling period for the state with visual recognition, when integrating is based on the stop frequency of menelipsis signal S10 and based on the stop frequency of menelipsis signal S11 respectively, and these stop frequency sums of integrating.

Control device 20 carries out with the synchronous state control loom of the rotation of the main shaft 33 of loom the time beyond the demonstration of Weft-insertion-condition, in order to carry out other necessary control, select signal generation 42 to constitute by wefting insertion control part 31, master control part 36, statistical value calculating part 38, setting/display part 41, weft yarn.In order to detect the anglec of rotation of main shaft 33, encoder 34 is attached at main shaft 33, the signal of the anglec of rotation θ of main shaft 33 takes place in encoder 34 in weaving, this is delivered to wefting insertion control part 31, master control part 36, weft yarn selection signal generation 42, statistical value calculating means 40 etc.

Master control part 36 is carried out the control of main motion of loom or the control when stopping according to the signal of the anglec of rotation θ of main shaft 33.Weft yarn selects signal generation 42 from the rotation amount of anglec of rotation θ sensing main shaft 33, select signal S8 according to predefined weft yarn selecting sequence generation weft yarn, select signal S8 to deliver to wefting insertion control part 31, statistical value calculating means 40, computing means 54 this weft yarn.Wefting insertion control part 31 is synchronous with the rotation of main shaft 33, the weft yarn 4 of signal S8 is selected in selection corresponding to weft yarn, the action of the length measuring weft storing device 5 in the basis control weft inserting apparatus 1 of the anglec of rotation θ suitable to the weft yarn selected 4, main burner 10, auxiliary jet 11, the wefting insertion action of the weft yarn of selecting 4.

Statistical value calculates means 40 in order to calculate the statistical value relevant with arrival period of weft yarn 4 period between each predetermined sampling period based on the arrival of the detected weft yarn 4 of each wefting insertion, according to the signal of anglec of rotation θ the anglec of rotation (0 °) of benchmark by the time latitude number (wefting insertion number of times) counted, and continue between the sampling period of predefined predetermined hits (latitude number), it is the arrival angle of weft yarn 4 that the input time of yarn signal S1 from the anglec of rotation θ detects the anglec of rotation θ that weft yarn arrives, and calculates the statistical value that weft yarn arrives period between each sampling period.Weft yarn arrives the statistical value in period and selects the input of signal S8 to calculate respectively by each yarn kind by weft yarn.

Refer to that at this alleged statistical value minimum of a value (anglec of rotation θ that the fastest weft yarn arrives), maximum (anglec of rotation θ when the slowest weft yarn arrives) and weft yarn that the weft yarn of wefting insertion opposition side arrives period (anglec of rotation θ the during arrival of weft yarn 4) arrive the value 1 or more in the standard deviation in period, and the mean value (anglec of rotation θ) in weft yarn arrival period.As above-mentioned, calculate these values by each yarn kind.

The differences of maximum and minimum of a value 2 values except the expression weft yarn arrives the deviation amplitude in period, the actual value of the deviation range of each value representation between sampling period.In addition, owing to be actual value, so compare with standard deviation, the scope of more knowing deviation more helps the adjustment of loom.

According to these maximums, minimum of a value, owing to know these amplitudes of fluctuation, therefore, in the adjustment of loom, for example favourable with the aspects such as pressure of nozzle (main burner 10 and auxiliary jet 11) at variable wefting insertion.Standard deviation shows extent of deviation by numerical value, corresponding to the height on the decentralization in the bi-distribution, so-called mountain.To this, as literal, mean value is the predetermined latitude number between 1 sampling period, for example is the average value that weft yarn in 1000 latitudes arrives angle, and from then on weft yarn arrives the rough change of angle as can be known.

Setting/display part 41 is with Fig. 2 aftermentioned, its display unit for being used for the statistical value demonstration or showing the information relevant with the main cause of the flight change that makes weft yarn, hits in being set between 1 sampling period for example has the setting input medium 37 of touch plate type.When the calculating of statistical value, the hits between 1 sampling period can be selected setting by the setting picture of settings/display part 41 from a plurality of.

In the setting operation before weaving beginning, the setting picture and selecting of operating personnel from the demonstration of being undertaken by setting/display part 41 set suitable sampling latitude number.Be between 1 sampling period at this alleged hits, arrive the number of measured value regularly when calculating weft yarn and arriving regularly statistical value as the weft yarn on basis.Example as described later, when sampling latitude number was set at 1000 latitudes, statistical value calculates means 40, and to arrive measured value regularly with the weft yarn of 1000 latitude parts be the statistical value of basic calculation between 1 sampling period.And, the memory capacity of statistical value be made as be equivalent at least 1 yarn tube part for the sampling latitude number of yarn body 3 part.

Statistical value calculates means 40 for based on the data computation statistical value of pressing the weft yarn color samples, to select the weft yarn of signal generation 42 to select signal S8 as input from weft yarn, press the weft yarn color calculate the value 1 or more in maximum that weft yarn arrives period, minimum of a value that weft yarn arrives period, the standard deviation that weft yarn arrives period, and weft yarn arrive the mean value in period, will output to setting/display part 41 for the display data signal S9 of these statistical values of demonstration.

And, computing means 54 are calculated stop frequency in order to press the weft yarn color, when the input weft yarn is selected signal S8, to stop latitude signal S2, S3 and menelipsis signal S10, S11 as input, between each sampling period, while the stop frequency of identifying parking reason integrating loom, press each weft yarn color generation display data signal S12 based on the integrating result.This display data signal S12 is in order to show that stop frequency as the demonstration that stops situation occurred of loom, outputs to setting/display part 41.

As above-mentioned, setting/display part 41 shows for the diagram of the statistical value that shows relevant wefting insertion or the information relevant with the main cause of the flight change that makes weft yarn 4 namely changes the demonstration of main cause information and arranges.Statistical value calculating part 38 (statistical value calculates means 40 and computing means 54) receives from setting/display part 41 and is used for the diagram required instruction of demonstration and display data signal S9, S12 are outputed to setting/display part 41.The data that show or change the setting change of main cause information, other weaving conditions for the statistical value of the data that exchange the setting of statistical value The conditions of calculation, relevant wefting insertion, but setting/display part 41 selects signal generation 42 twocoueses to communicate by letter mutually for wefting insertion control part 31, master control part 36, weft yarn, in addition, in order to exchange diagram data presented such as statistical value, but calculating means 40 for statistical value, setting/display part 41 communicates by letter mutually with computing means 54 twocoueses.

And, receive display data signal S9 in the end of setting/display part 41 between each sampling period, S12, data based on display data signal S9, sequence storage on time follows woven process to calculate the statistical value that means 40 calculate successively by statistical value, on the time shaft of display frame when the diagram of time ground shows the size of stored statistical value, based on the data of display data signal S12, but showing on the identical time shaft of the time shaft of usefulness that with the diagram of above-mentioned statistical value the situation occurred that stops that state with visual recognition is presented at the loom that takes place between above-mentioned each sampling period is stop frequency.

Fig. 2 illustrates the configuration example of the inside of setting/display part 41.In Fig. 2, setting/display part 41 has storage part 46, touch plate type view display 47, port 48, handling part 49.Port 48 receiving and counting values show the display data signal S9 of usefulness, the display data signal S12 that stop frequency shows usefulness etc., carry out the transmitting-receiving of signal or data between statistical value calculating means 40 exclusive disjunction means 54 externally and inner view display 47, the handling part 49.

Storage part 46 can be rewritten, corresponding to the data of the stop frequency of the data of a plurality of statistical values of sampling number storage display data signal S9, display data signal S12.Store program for control touch plate type view display 47 at this storage part 46, be used for program, other necessary softwares that the diagram of statistical value or stop frequency shows.

View display 47 is display unit, based on display data signal S9 in the size that shows a plurality of statistical values on the time shaft of display frame through the diagram of time ground, but and showing the stop frequency that is presented at the loom that takes place between each sampling period on the identical time shaft of the time shaft of usefulness as the state of visual recognition based on display data signal S12 with the diagram of statistical value.And view display 47 constitutes: a part of dual-purpose touch plate type in display frame is set input medium 37, the data by can importing display requirement or various instruction, hits to the touch operation of display frame etc.The data of hits etc. are delivered to statistical value via port 48 and are calculated means 40 exclusive disjunction means 54.

Setting/display part 41 has the 1st Presentation Function, the 2nd Presentation Function as Presentation Function.The 1st Presentation Function is to show the statistical value relevant with arrival period of weft yarn 4, and the information relevant with main cause that the flight of weft yarn 4 is changed at identical picture, namely changes the function of main cause information.In addition, as describing in detail among subsequent figures 3 and Fig. 4, this change main cause information is presented at the hurdle of " operation information ".And as described later, the 1st Presentation Function comprises that also the situation occurred of parking is divided into the unusual parking of following weft yarn 4 and follows the unusual parking of warp thread 13 and the function that shows.

And the 2nd Presentation Function is shown enlarged on the time shaft during the appointed part, and the function of the situation occurred of the above-mentioned parking in showing during this amplification by the parking reason.And, when this amplify to show, the function of the information that the setting of the weaving condition that carries out during being included in also on the identical picture that as input resume guide look shows that this amplifications of expression shows is changed.

Handling part 49 is made of the so-called microprocessor of CPU, in the time of according to the input and output on the predetermined software control port 48 that is stored in storage part 46, control view display 47, read a plurality of statistical values or stop frequency etc. according to the requirement that the picture from setting/display part 41 shows from storage part 46, and show diagram demonstration and the stop frequency corresponding with a plurality of statistical value sizes at view display 47.

As more than, statistical value calculating part 38 and setting/display part 41 with the integrating of the computing of statistical value or stop frequency, these storages so that with the size of the statistical value of storage or stop frequency on the time shaft of display frame through the time ground diagram show, but this function can be utilized the control computer of master control part 36, perhaps the computers such as microcomputer by special use constitute, and also can handle by its software and realize.

In addition, in the configuration example of Figure 1 and Figure 2, as the piece formation of each function, but these also can constitute as 1 piece by utilizing computer.And the function of control device 20 also can be used computer, is realized by program.Thereby the part of the functional block of control device 20 can be replaced by input-output means, storage means, computing (control), the demonstration means of computer.

Then, Fig. 3 and Fig. 4 illustrate an example of the display frame 61 of the statistical value that is shown by view display 47.Statistical value, stop frequency and the change main cause information of the display frame 61 of Fig. 3 between per 1 sampling period of 1 picture demonstration weaving process.About on the time shaft of the size of the statistical value in arrival period of weft yarn 4 (arriving regularly) through the time diagram show that (below, be also referred to as " demonstration relevant with statistical value ") expresses as the figure of transverse axis (X-axis)/longitudinal axis (Y-axis).1 unit of the transverse axis in the chart is between 1 sampling period.In addition, the scale of transverse axis is the latitude number, and the process of the time of this latitude number when weaving is proportional.Therefore, transverse axis can be described as time shaft.

Hits between sampling period (latitude number) can be selected setting by the touch operation to the selection button 43 of " 32 ", " 100 ", " 1000 " in as the display box 57 of setting input medium 37.In the part of the selection button 43 of " 1000 " with hatching, but this expression is set at the hits between 1 sampling period the situation of 1000 latitudes.

In the past of now of demonstration "-" (negative sign) expression " 0 " of the transverse axis of illustrated chart.Thereby, " 10 " be between 10 the sampling period of now of " 0 " before, by the calculating of 10 * 1000 (hits)=10000 represent before 10000 latitudes wefting insertion constantly.Like this, chart is being recalled expression during time of weaving of the hits 100 in the past of " 100 " from " 0 " on the transverse axis, and total latitude number of this period becomes 100000 latitudes.During this demonstration by the touch operation to the scroll button 44 of the warning triangle of left and right directions, as required can be mobile arbitrarily on time shaft.

And, in the chart of display frame 61, in the left and right sides longitudinal axis (Y-axis), angle by anglec of rotation θ of the longitudinal axis in left side (°) arrival period of expression weft yarn 4, the longitudinal axis on right side is represented the size of standard deviation.

And, in the chart of display frame 61, the graph A of broken line on time shaft with the longitudinal axis angle in left side (°) as showing that with reference to the scale diagram weft yarn in hits 1000 latitudes arrives the mean value in period (weft yarn arrival angle).And, discontinuous rod chart B on time shaft with the longitudinal axis angle in left side (°) as with reference to scale, connect as the line segment with y direction that weft yarn in hits 1000 latitudes arrives the maximum in period (weft yarn arrival angle) and the graphical state of minimum of a value shows.And the chart C of broken line illustrates the standard deviation that weft yarn arrives period (weft yarn arrival angle) with the longitudinal axis on right side as the reference scale on time shaft.

In addition, the yarn kind for yarn body tag 45 expression weft yarns 4 on the top of display frame 61 is color C1, C2 and the yarn kind that the weft yarn 4 in the demonstration is shown.The yarn body tag 45 that supplies in " 1 " has hatching, but this expression is carried out the picture demonstration about color C1.Under the situation of multicolor weft insertion loom, by to the touch operation for yarn body tag 45, can select the yarn kind (color) of weft yarn 4 in display frame 61, also changeable weft yarn for the yarn kind selected arrives the diagram in period and shows.Explanation in passing, if constitute view display 47 is shown as polychrome (color), make the demonstration look difference of each chart (A, B, C) or transverse axis, the left and right sides longitudinal axis etc. respectively, or make demonstration look difference and show that simultaneously then visual recognition further improves by the yarn kind.

And, in illustrated example, in display frame 61, setting/display part 41 based on the 1st Presentation Function the diagram relevant with the statistical value in the picture show above, as the situation occurred of the parking of loom parking information is divided for by the parking that causes unusually " weft yarn parking " of weft yarn 4 parking that causes unusually " warp thread parking " by warp thread 13 or limit yarn 51, these are diagrammatically shown on the transverse axis, and show that on the hurdle of " operation information " information relevant with the main cause of the flight change that makes weft yarn of the present invention namely changes main cause information.

In illustrated example, about the demonstration of above-mentioned parking information, differentiate these stop frequencies according to display mode easily by vision only is for 1 time or repeatedly, that is, but show with the display mode of visual recognition stop frequency.In addition, show in the example at this, do not show " weft yarn parking " and " warp thread parking " sum (stop frequency of total), but also can show by the appropriate display mode as required.And, can not be divided into " weft yarn parking " and " warp thread parking " yet and only show both sums.

And, about " weft yarn parking ", the bad stop frequency that causes of wefting insertion that takes place when showing wefting insertion by selected color by weft yarn color (yarn kind).Therefore, can be by yarn kind identification stop frequency.

And, if the display mode to above-mentioned parking information explains, then in display frame 61, the demonstration that " weft yarn parking ", " warp thread parking " reach " operation information " shows that with respect to being used for diagram the time shaft (X-axis) of size of statistical value is parallel, on the auxiliary axle corresponding to the scale of this time shaft, between each sampling period as the stop frequency demonstration that between this sampling period, takes place (1000 latitude) in.Because the time scale (latitude) of auxiliary axle herein is time scale (latitude) " 10 ", " 20 ", " 30 " with above-mentioned time shaft ... the scale of identical distance is presented at the statistical value demonstration with on the identical time shaft of time shaft so can be considered as stop frequency (" weft yarn parking " and " warp thread parking ").But, show the blank of usefulness if can guarantee to stop at the time shaft (X-axis) that is used for the diagram demonstration, then these stop frequencies also needn't utilize the auxiliary axle parallel with respect to time shaft (X-axis), and can directly be presented at the blank on the above-mentioned time shaft.

Explanation in passing, " weft yarn parking " become stopping latitude signal S2 and stopping latitude signal S3 sum (total) from the 2nd bobbin feeler 22 from the 1st bobbin feeler 21.State as preceding, the content of " weft yarn parking " causes by wefting insertion is bad, but also can comprise the parking of following for yarn breakage.When comprising the parking of following broken end, though it is not shown, but arranging for the yarn breakage sensor for the path of the weft yarn 4 between yarn body 3 and the length measuring weft storing device 5 is first-class, calculate with the same area of the information of the 1st bobbin feeler 21 and the 2nd bobbin feeler 22 and handle these for the signal of yarn breakage sensor.

And " warp thread parking " becomes from the menelipsis signal S10 of menopause tablet device 50 with from the menelipsis signal S11 sum (total) of selvage device 52.Be also referred to as menopause tablet by stopping of causing of the cut-out of warp thread (body warp) 13 and stop, being also referred to as the leno broken end by stopping of causing of the cut-out of limit yarn (leno yarn) 51 and stopping.Selvedge is being arranged with in the loom of line, selvedge is also included within " warp thread parking " with the line broken end.

Like this, but the state of the frequency that setting/display part 41 stops the situation occurred that stops with visual recognition by the 1st Presentation Function show.Show by this to differentiate in the unusual reason of statistical value appearance whether come self-stopping n easily.And, the situation occurred (stop frequency) that stops is divided into the unusual parking of following weft yarn 4 and follows the unusual parking of warp thread 13 to show, so by the different situation of considering along with the parking reason statistical value to be brought of influence, the operating personnel can differentiate more exactly in the unusual reason of statistical value appearance whether come self-stopping n.

In addition, if the display mode according to Fig. 3 and parking information shown in Figure 4, then the stop frequency diagram between each sampling period is shown as the rod wire, amplifies key diagram as seen as the part in the auxiliary illustrated circle of Fig. 3, and its number of times can visually be judged according to its bar line number (thickness).At length, in the diagram image of illustrated rod wire, when stop frequency becomes more than 2 times, the bar line of 1 part is spacing and only arrange this number of times part in X direction (X-direction) not, therefore, in the time of when stop frequency is 1 time and more than 2 times, visually become big form by visual recognition as the bar line thickness.But, be more than 2 times the time at stop frequency, also can leave the demonstration that is spaced corresponding to the rod wire of stopping for 1 time, at this moment, stop frequency is confirmed as the bar line number.

And, in illustrated example, to the displayable system of being limited in scope between each sampling period in display frame 61, maximumly can carry out 3 scales (3 point) demonstration till 3 parts part namely in the direction of time shaft.Therefore, even stop frequency is more than 4 times, this demonstration still becomes the demonstration identical with 3 times.Particularly, be 3 points (dot) part corresponding to the indication range of (1000 latitude) between each sampling period in X-direction (the process direction of time), be 1 point in transverse axis (X-axis) direction, be 17 diagram image in height (Y-axis) direction corresponding to 1 time the above-mentioned demonstration (bar line) of stopping.Thereby, in the demonstration example of Fig. 3 and Fig. 4, can be shown to part in indication range 3 times as the maximum of stop frequency.

Like this, in illustrated example, can only be shown to part to stop frequency 3 times as maximum.But, in the weaving of reality, between 1 sampling period of maximum 1000 latitudes, surpass parking more than 3 times with identical parking reason (weft yarn stops or warp thread stops) and be originally unusually and take place in fact hardly, so accessible in practicality.

In addition, demonstration to stop frequency, have and stacked towards Y direction according to stop frequency corresponding to the block diagram image of the same amplitude of the indication range between sampling period, also can show that by the rod chart according to height change perhaps also available digital shows stop frequency.If like this, needn't dwindle the scope of shown time shaft and can show many stop frequencies.

Thereby, to the demonstration of stop frequency, needn't set as above-mentioned maximum stop frequency, can show the stop frequency of larger amt, also can in statu quo show actual stop frequency.Like this, but the any-mode that the demonstration under the state of the visual recognition of above-mentioned stop frequency refers to limit the situation of displayable stop frequency and do not limit the situation of displayable stop frequency.

Then, demonstration about the change main cause information in the illustrated display frame 61, in illustrated example, between the display field of the display field of the chart of statistical value and " warp thread parking ", be provided with the display field that is designated as " operation information ", show that at this display field the relevant information of main cause that changes with the flight that makes weft yarn 4 is above-mentioned change main cause information.The display field that is designated as this " operation information " is arranged on respect on the parallel auxiliary time shaft of time shaft (transverse axis), at mark " P ", " R ", " W " of this demonstration corresponding to above-mentioned change main cause information.The meaning of these marks is opened little window by touching the legend button 32 among Fig. 3 as Fig. 4, the operation information explanation picture 35 in this window mark content as can be known.

At operation information marking in the content of picture 35 is described, the information that " P " (yarn cylinder sensor) expression is relevant with the switching that supplies yarn body 3, and expression is changed the moment that supplies yarn body 3 based on the detection signal S4 from yarn cylinder sensor 39.The execution of " R " (weft yarn control reset) expression by wefting insertion control according to the arrival angle change wefting insertion condition of weft yarn 4 (for example, wefting insertion begins regularly) afterwards, the information relevant with the reset operation that carries out turning back to initial value for this wefting insertion condition that will change, and the moment of initial value is returned above-mentioned wefting insertion condition in expression.And " W " (pattern change) expression is as the moment of the patterns of openings of a routine information-change warp thread 13 relevant with the change of weaving condition.

If write up is carried out in control to above-mentioned wefting insertion, according to loom following loom is arranged: the arrival angle control wefting insertion based on detected weft yarn 4 begins regularly the wefting insertion condition that (injection beginning of the regularly open and/or main burner 10 of card shotpin 8 regularly) wait and has the arrival timing automatic control function of certainization roughly that makes weft yarn 4.And, as above-mentioned, exist the arrival timing of weft yarn 4 according to the tendency of the minimizing variation of following the woven winding diameter that supplies yarn body 3 that carries out, therefore, in the loom that has as above-mentioned automatic control function, control above-mentioned wefting insertion condition according to the minimizing of the winding diameter that supplies yarn body 3.

And, the reset operation of above-mentioned wefting insertion control (resetting of weft yarn control) refers to following operation, namely, residual yarn amount for yarn body 3 is followed woven becoming below the scheduled volume, perhaps exhaust the weft yarn 4 for yarn body 3, follow confession yarn body 3 to be switched to another new confession yarn body 3, will return initial value by the above-mentioned wefting insertion condition of automatic control change.

Become the input of master control part 36 from the detection signal S4 of yarn cylinder sensor 39, master control part 36 follows the input of detection signal S4 to carry out the control that stops of loom.And, undertaken or carry out automatically by the operating personnel for the replacing of yarn body 3, then, master control part 36 is restarted loom and is begun to weave again.At this moment, will begin regularly to get back to the reset operation of initial value by the wefting insertion of above-mentioned automatic control change, and in the loom of the replacing that supplies yarn body 3 by the operating personnel, operate SR by the operating personnel and carry out.

And, in having the loom of automatic replacing for the function of yarn body 3, be input to wefting insertion controller 31 by detection signal S4, carry out reset operation by the inter-process of wefting insertion controller 31.At this, according to following the wefting insertion that carries out from the detection signal S4 of yarn cylinder sensor 39 to begin reset operation regularly, detection signal S4 can be considered the information relevant with the main cause of the flight change that makes weft yarn 4, namely changes main cause information.And, except master control part 36 and wefting insertion control part 31, also become the input of setting/display part 41 as this detection signal S4 that changes main cause information.

In addition, as at Fig. 1 with shown in the dotted line, when using for yarn body 3, this is made as wefting insertion continuously for yarn body 3 as the terminal of the weft yarn 4 that supplies yarn body 3 more than 2 that will use successively and the so-called tieing state of beginning wiring, replace above-mentioned yarn cylinder sensor 39, use is set to 2 tieing sensor (connecting sensor) 39a that supply between the yarn body 3 of tieing state, the detection signal S4 that the detection signal of this tieing sensor 39a replaces from above-mentioned yarn cylinder sensor 39 becomes the signal that shows for the switching of yarn body 3, is input to main control unit 36 etc. as change main cause information.

Above-mentioned change main cause information is not limited to diagram, but also signifying word and other weaving conditions, for example relevant information of the change of the revolution of wefting insertion pattern, weft count, loom and showing.And the mark that shows as change main cause information is not limited to the mark based on as shown 1 writing letter, also other discernible marks or text line etc.The mark that also can show in addition, its change main cause information in the amplification display frame 62 of Fig. 5 described later and Fig. 6.Display frame 61 as Fig. 3 and Fig. 4, in single display frame 61, become the demonstration on the identical picture under the situation of the demonstration of the demonstration of demonstration statistical value and change main cause information certainly, carrying out statistical value in display frame 61 shows, the operation information of another window of opening in display frame 61 explanation picture 35 changes under the situation of demonstration of main cause information, and statistical value shows and the demonstration of change main cause information also becomes demonstration on the identical picture.

Then, 2nd Presentation Function of Fig. 5 to Fig. 7 by setting/display part 41 illustrates the example of amplification display frame 62 of the particular range of display frame 61.Display frame 61 at Fig. 3 or Fig. 4, if operating personnel's designated duration on time shaft, then as Fig. 5 to shown in Figure 7, settings/display part 41 have by another amplify display frame 62 show significantly pass through given settings during in the relevant demonstration of the statistical value with the time of advent and the function (the 2nd Presentation Function) of the demonstration of stop frequency.In addition, in illustrated example, do not put down in writing the information relevant with the main cause of the flight change that makes weft yarn 4 (change main cause information) in amplification display frame 62, but this demonstration also be may be displayed on amplification display frame 62.

The example of Fig. 5 to Fig. 7 shows that for replacing the preceding display frame 61 of amplification demonstration to replace another amplifies the mode of display frame 62.But, this amplification display frame 62 also still the display frame 61 before the residual amplification and on this picture with the overlapping demonstration of the state that staggers, also can be used as 2 divided frames and amplify display frame 61 before showing and arrange and show.In addition, in illustrated amplification shows, by the parking reason, namely show the stop frequency of the situation occurred that expression is stopped by the classification of the detector that detects this parking reason (sensor).But, be an example eventually during the illustrative demonstration, dwindle during the demonstration on the time shaft, if get the interval of the scale of X-direction significantly, then can show in further detail.In addition, the amplification display frame 62 of Fig. 5 is by touching the display frame 61 that bottom-right X button 55 returns Fig. 3.

As mentioned above, view display 47 is set input medium 37 with the touch plate type dual-purpose.Therefore, the operating personnel comes the scope that will amplify demonstration on the setting-up time axle by the ad-hoc location that touches display frame 61.At this moment, the touch of display frame 61 partly has the function of setting input medium 37.Particularly, near the picture of the operating personnel pars intermedia of the part that will amplify demonstration on the time shaft by touch, become corresponding with it 1 appointed state constantly, set by during the amplification that constitutes during the front and back that are benchmark with this appointed moment predefined.

But, to setting during this period, be not limited to amplify demonstration during intermediate point be appointed as moment of benchmark, also can with during beginning or end be appointed as the moment that becomes benchmark, also can based on this setting to amplify demonstration during.In addition, also can replace based on appointed 1 constantly and set during predefined to amplify demonstration during, and 2 constantly and during the setting of the beginning of designated duration and end.And the appointment in the above-mentioned moment (intermediate point, initial point, terminal point) on the basis of setting during becoming is not limited to touch display frame with touch plate type, also can import numerical value such as latitude number and specify (setting).

In addition, at this, the above-mentioned required movement of setting during being used for (during setting operation) has both simultaneously and amplifies the operation that shows.In other words, only carry out during setting operation and amplify demonstration automatically.But setting operation and amplification display operation also can be operated respectively during these, and the setting that also can change magnifying power when amplifying the operation that shows arbitrarily gets final product.

And, as above-mentioned, set based on the moment by any appointment of operating personnel during the amplification demonstration.Namely, be not limited to set arbitrarily to amplify demonstration during, during setting/display part 41 preestablishes specifically according to setting value (numerical value of the time value in past or latitude number in the past) in advance, during for example with the now being predetermined before this of starting point, do not carry out above-mentioned during setting operation and by amplifying the operation of demonstration, also can amplify the demonstration that shows during set predetermined.And, setting operation during amplifying display operation and have both simultaneously this moment.

And, in Fig. 5, be the legend button 53 of " legend " if the operating personnel touches the top-right content that marks of amplifying display frame 62, then as shown in Figure 6, at the window of the little explanation usefulness of identical picture demonstration, occur explaining orally picture 58 at this window, show necessary item at this.Particularly, show the corresponding relation of each display mark and each parking reason in the display box 59 of the stop frequency in explaining orally picture 58, above-mentioned each display mark represents to make the display mode difference and the stop frequency of demonstration.

In illustrated example, each former reason title (H1 detector, H2 detector, menopause tablet and leno) expression for detection of the detector (sensor) of each parking reason of stopping.Explanation in passing, above-mentioned H1 detectors is in the 1st bobbin feeler 21 and sensor 24, based on the loom of the sensing result of H1 detector stop to be also referred to as H1 and to stop.And above-mentioned H2 detectors is in the 2nd bobbin feeler 22 and sensor 25, and according to the sensing result of H2 detector, the stopping of loom is also referred to as H2 and stops.

And, in the display box 60 of the arrival angle that explains orally picture 58, marking statistical value, i.e. diagram shows each line kind of usefulness and maximum/minimum, on average reaches the corresponding relation of standard deviation.In Fig. 6, explain orally picture 58 and close by touching the bottom-right button of closing 56.

Like this, when time shaft amplifies the scope that shows appointment, show the situation occurred of above-mentioned parking by the parking reason, therefore, the operating personnel is easy to visually confirm the unusual of statistical value, can considers concrete parking reason, therefore, can carry out the differentiation of its reason more accurately.

The operating personnel confirms the result of displaying contents, if can be easily the unusual reason that statistical value occurs be differentiated the reason that causes for the parking by loom, then can be judged as and not too give weaving and bring influence from now on, also may ignore.On the contrary, although occur unusually on the statistical value, under the situation of the parking of the number of times that effect does not take place between this sampling period to bring to statistical value, not to stop can be judged as its reason, can infer whether the unusual etc. of weft yarn 4 or device is reason.According to this demonstration, can judge easily whether as the reason that appears at statistical value unusually be to stop, and carries out determining of reason based on this at shorter time.

Then, Fig. 7 is the example as " input resume " demonstration information relevant with the change of the setting value of weaving condition (especially, wefting insertion condition).In the amplification display frame 62 of Fig. 5, the operating personnel is if touch the top-right input resume button 63 that amplifies display frame 62, then as shown in Figure 7, show that at identical picture little input resume show the window of usefulness, relevant " the input resume " of change of the setting value of demonstration and the weaving condition display frame 64 of the input resume in this window in the wefting insertion condition of an example (in the illustrated example as).In display frame 64, be illustrated in be exaggerated demonstration during the information of change of setting value of the wefting insertion condition of being undertaken by operating personnel's input shown according to the order that information more ancient on the time is positioned under the picture as resume.But as described later, about the demonstration of the information of the setting value change of representing this wefting insertion condition (below, be also referred to as " setting modification information "), " amplify and show " or " during specify " is optional, carries out as required.

In addition, in Fig. 5, shown under this picture, if be set at 1000 latitudes between 1 sampling period, then Fig. 7 amplify demonstration during be from relevant with the wefting insertion of the weft yarn 4 of color C1 current before 11 sampling periods during, in other words, be that the weft yarn 4 of color C1 is by during between wefting insertion 11000 latitudes.If this with during the weaving of loom, for example select wefting insertion 4 barry dyeing yarns 4 equably, during then above-mentioned be in this loom, carry out 44000 latitudes wefting insertion during.And, the setting modification information of the wefting insertion condition that comprises in the shown input resume becomes and is illustrated in and the information of carrying out based on the change of the setting value of the wefting insertion condition of carrying out during the weaving of loom corresponding during the wefting insertion of 11000 latitudes of the weft yarn 4 of this color C1.

And in the example of Fig. 7, the display frame 64 of above-mentioned input resume shows with the state that overlaps display frame 62 at the display frame 62 different windows that show with statistical value.Like this, in the example of Fig. 7, another window is opened in amplification display frame 62 at Fig. 5, demonstrates the input resume in the display frame 64 of this window as the setting modification information of wefting insertion condition, but we can say that this display mode also shows that at identical picture statistical value shows and the input resume.In addition, the display frame 64 of demonstration input resume replaces showing to overlap the mode of amplifying display frame 62 as above-mentioned, also can arrange and be presented on the identical picture with amplification display frame.And, at display frame 61 designated durations of Fig. 3 or Fig. 4, also can show this input resume during appointed at the picture identical with display frame 61.

Explanation in passing, in the display frame 64 of input resume, button 23 is the buttons for the picture rolling that makes demonstration, uses during the direction moving image down.And X button 65 is closed the window of the display frame 64 of input resume, uses when only returning previous display frame 62.

About the demonstration example of illustrated input resume, each content displayed is as follows.The object apparatus of change is set in " secondary 1 " in the display frame 64, " auxiliary main ", " master ", " card shotpin " expression, represents the 1st group auxiliary jet 11, auxiliary main burner 10a, main main burner 10b, card shotpin 8 respectively.In addition, the auxiliary jet 11 of each group is from consist of the 1st, the 2nd near main burner 10 ...

" C1 ", " C2 " correspond respectively to color 1, color 2, the expression at multicolor weft insertion device 1 by the setting value of any weft yarn in a plurality of weft yarns 4 of wefting insertion.When carrying out wefting insertion using the main burner 10 more than 3 (also comprising from the situation of the identical weft yarn 4 of main burner 10 wefting insertion more than 2), and then become " C3 ", " C4 " ...

If the nozzle that wefting insertion is used (main burner 10, auxiliary jet 11), then " ON ", " OFF " represent the injection beginning timing respectively, spray stop timing.Under the situation of card shotpin 8, " ON " expression debouches drum barrel 7 by retreating timing, " OFF " expression that weft yarn 4 is made as the state that can alleviate, and is made as and can blocks the only timing of the state of weft yarn 4.

And, mark in the content in " 65 → 70 ", " 185 → 190 " etc., the anglec of rotation θ (angle of bend) of the main shaft 33 of each numeral loom, expression setting value from 65 ° of angle of bend change to 70 °, from 185 ° of situations that change to 190 ° of angle of bend.

The period of this setting change is carried out in expressions such as [2] of the rightmost side, [6], and [2] represent to set between 2 current sampling periods before the situation of change.Namely, when showing a plurality of modification information on the resume, need and to have carried out this setting change constantly which is held in, so the modification information of the weaving condition in the illustrated example is not only object apparatus or it sets value, and also comprises the information (period information) relevant with the period of changing (time).

According to above definition, before for example " secondary 1 C1 ON, 65 → 70[-2] " is illustrated between 2 sampling periods of the statistical value relevant with color 1 during with weft yarn 4 wefting insertion of color 1 injection beginning of the 1st group 11 groups of auxiliary jets regularly from 65 ° of situations that change to 70 ° of angle of bend.

But, in illustrated input resume show, be not the color by weft yarn 4, the setting modification information that is used for the wefting insertion condition of different weft yarns 4 mixes, and all information of change that are illustrated in the setting value of the wefting insertion condition of carrying out during above-mentioned show as resume.Like this, shown input resume are not limited to only to show the modification information of setting value that shows the wefting insertion condition of corresponding wefting insertion to weft yarn 4 with the statistical value that demonstrates, and also can comprise the modification information to the wefting insertion condition of the wefting insertion of another weft yarn 4.And as described later, the setting modification information of the condition relevant with wefting insertion (wefting insertion condition) weaving condition in addition is also included within the input resume and shows.

But as above-mentioned, also consider following situation: if in the display frame 64 of input resume, also show the modification information that shows the setting value of the weaving condition that it doesn't matter with the statistical value that demonstrates, then the operating personnel carries out wrong judgement according to the demonstration item.For example, show at the statistical value relevant with the weft yarn 4 of color C1, when showing the input resume owing to noting abnormalities at statistical value, although only will confirm the modification information to the wefting insertion condition of the wefting insertion of the weft yarn 4 of color C1, show other more modification informations in identical display frame, then have this affirmation to need the possibility of time.And, when occurring change between sampling period identical during unusual to the wefting insertion condition of the wefting insertion of another weft yarn 4 with statistical value, this modification information might be thought by mistake the worry of the information relevant with the weft yarn 4 of color C1.Therefore, in order to prevent misidentification, the setting modification information of the weaving condition that will show as the input resume only as show corresponding to shown statistical value corresponding to the information of the wefting insertion of weft yarn 4 or shown to the modification information of the setting value of the weaving condition of the wefting insertion of other weft yarns 4.And, for dwindling the demonstration number, can specify specific weaving condition (for example, the injection timing of main burner 10 or auxiliary jet 11), also can only show the input resume relevant with the modification information of the setting value of this appointed weaving condition.

According to above concrete example, in the work of weaving, in the display frame 61 of Fig. 3, at the statistical value (mean value relevant with the arrival period (arrival angle) of weft yarn 4, maximum/minimum, when standard deviation) upward appearance is unusual, the operating personnel on the time shaft of this display frame 61 according to unusual chart characteristic (the broken line graph A of mean value, the rod chart B that links maximum and minimum of a value, the broken line chart C of standard deviation) confirms unusual condition or unusual position, and information (change main cause information) i.e. " P " (yarn cylinder sensor) relevant with the main cause of the flight change that makes weft yarn 4 confirmed on the hurdle of the operation information from this identical picture, " R " (weft yarn control resets), having or not of " W " (pattern change) is at time shaft contrast unusual condition or unusual position and " P ", " R ", " W " has or not.

By the contrast on these the time shaft, can determine easily whether the abnormal cause of statistical value is caused by shown " P " (yarn cylinder sensor), " R " (weft yarn control resets) or the information of " W " (pattern change).Like this, except the statistical value relevant with the arrival period (arrival angle) of weft yarn 4, can on the time shaft of identical display frame 61, directly contrast change main cause information, therefore, even unusual causal definite various reasons of not inferring of statistical value, do not need a lot of time yet, can from display frame 61, visually carry out reliably.

Especially, for the switching of yarn body 3 time or during the resetting of wefting insertion condition (timing that wefting insertion begins), tendency with flight change of weft yarn 4, but can be on time shaft the change reason of sequence contrast on time this moment and the diagram of the statistical value relevant with arrival period show, owing to from visually reading both corresponding relations, can determine causality at short notice easily.

When this contrasts, during the corresponding relation on time shaft definite insufficient, the operating personnel is designated duration in display frame 61, show as the amplification picture between the sampling period of Fig. 5 and show 62, also can check unusual generation constantly, and, touch legend button 53 or input resume button 63 as required, show the display frame 64 that explains orally picture 58 or input resume, carry out the affirmation of parking information (weft yarn stops, warp thread stops) or input resume (change of wefting insertion condition) information from these pictures.

According to these information, the operating personnel occurs between unusual sampling period at the statistical value relevant with the arrival angle of weft yarn 4, corresponding to this unusual statistical value, when the setting value of the wefting insertion condition of weft yarn 4 was changed, the change (setting value after changing) that can infer in this setting value had problem.Especially, between this sampling period, if in the parking according to the demonstration certifiable loom relevant with above-mentioned parking condition, or the information relevant with the switching of weft yarn 4 (for yarn body 3), with the reason that does not have to become problem in the change main cause information of the relevant information that resets of wefting insertion condition (wefting insertion begin regularly etc.) etc., then as the reason beyond the above-mentioned change main cause information, the change of the setting value of the weaving condition (wefting insertion condition) that will be undertaken by the operating personnel according to the information of input resume is judged as the strong candidate of reason, with reference to the display frame 64 of input resume, seek unusual reason as required.

Like this, if according to illustrated concrete example, except the statistical value relevant with the arrival period (arrival angle) of weft yarn 4, and change main cause information, show parking information (weft yarn stops, warp thread stops) simultaneously with these, again as required, but visual recognition input resume (wefting insertion condition).Thereby the unusual reason of statistical value can synthetically be determined on time series according to the viewpoint of change main cause information, parking information, input resume.

In addition, about the display mode at input resume shown in the above-mentioned concrete example etc., can implement as following distortion.

In above-mentioned concrete example, show and during setting in order to amplify, input resume in showing during this setting, but for it, can specify any time at time shaft, can show that also the information relevant with setting change of the quantity that sets is as the input resume from the setting change of carrying out in the moment in the most approaching moment of setting by this appointment successively.

At this moment, also can only be the setting change of carrying out before in the appointed moment, also can be used as the input resume and only show the setting number relevant with the setting change of before and after it, carrying out.

In addition, about during appointment, in illustrated example, be starting point and designated duration with current, but also can specify in the past arbitrarily during, show input resume during this period.And, during the omission or specific constantly appointment, for example, the also push-botton operation that can show by resume, show with current be during specific before this of starting point or the modification information of specific number as the input resume.

And, demonstration about the input resume, in illustrated example, only show that the information relevant with the change of the setting value of the weaving condition of relevant wefting insertion is as importing resume, but as other weaving conditions, also can comprise above-mentioned wefting insertion pattern, Warp opening pattern, weft count in the demonstration item of display frame 64 of input resume, change relevant information with the setting of the revolution of loom etc.That is, the information that comprises in the relevant information of the change with weaving condition in the information that also can the main cause with the flight change that makes weft yarn among the present invention is relevant and the information by operating personnel's change setting are included in the above-mentioned input resume and show.

In addition, about the demonstration of input resume, in above-mentioned concrete example, the modification information of respectively setting that shows as the input resume in the scope of appointment comprises the information (temporal information) when (between sampling period) carried out setting change as information.But, be narrow and small scope during appointed, for example be between specific 1 sampling period, then can omit this temporal information.And, omit the information relevant with the setting value that has been changed, the information that also can be used as only shows when changed which weaving condition.At this moment, also can show detailed information (setting value, detailed period, the operating personnel of change etc.) by another display frame.
