Description
The present invention relates to a kind of method that is used to control loom, this loom comprises that one has the weave mechanism of a shed open, yarn is carried by this shed open by at least one main weft yarn injector, pressure medium is fed to this injector, wherein at least the time of yarn arrival shed open end is detected, then should the time and the expectation time compare, afterwards, when there are difference institute's detection time and expected time, the medium that feeds to main ejector is adjusted, thereby the yarn speed in the shed open is changed so far, make the time of advent of being detected corresponding to the expected time.
From U.S. Patent No. 4722370, know the method for the above-mentioned type.
For the loom that the present invention relates to type, yarn is carried from the supply yarn storage cylinder by a main ejector and is passed shed open.Multiple natural phenomena, as pulse in main ejector from the variation of medium to the transmission of yarn, and the variation of the frictional force that when flying over shed open, runs into of yarn, the haulage time that the capital makes yarn pass shed open significantly changes, the time that causes yarn end to arrive the shed open end changes, and yarn arrives the rapid change of shed open end.Change on this time of advent for weaving process and the quality of woven product all have a negative impact, thereby need to eliminate as much as possible.
For achieving the above object, U.S. Patent No. 4446893 discloses a kind of loom, this loom comprises that one is arranged on the detector of shed open end, be used to detect the time of advent of yarn, average the above-mentioned time of advent that a plurality of weft yarns are inserted in the circulation, and the average time that will obtain like this and desired time of advent compare.When between the average arrival time that is detected and desired time of advent difference being arranged, the pressure that is fed to the medium of main ejector is adjusted to such effect, and promptly the starting velocity of yarn makes the relevant time of advent corresponding to the desired time of advent in next weft yarn insertion process.For this prior art loom, do not adjust before inserting having carried out a plurality of weft yarns.
In order in the weft yarn insertion process, to adjust, disclosed loom comprises that not only one is used to detect the detector of terminal time of arrival shed open in the above-mentioned U.S. Patent No. 4722370, and comprises that one is being positioned at the position probing speed and/or the detector of the time of advent of shed open starting point.Yarn speed with a kind of detectors measure weft yarn insertion process starting stage of back, if above-mentioned speed is different from desired speed, then will adjust to such degree, and in the weft yarn insertion process, regulate the speed and the weft yarn termination is arrived at the time point of expectation to the medium supply of main ejector.
When using said method, in fact yarn end will arrive shed ends at the time point of expectation, but the speed of yarn end arrival shed open end may be different fully, even far above desired value.
Peak tension in the yarn inserts when finishing at weft yarn at least, and yarn arrives the shed open end, even the speed in some time before, must be low as far as possible under the condition in front.In addition, above-mentioned arrival rate must can be reproduced as far as possible, just forbids minor variations.Low and reproducible arrival rate are favourable, not only in order to prevent peak tension, and relate to the braking procedure that yarn is subjected to when the weft yarn insertion process finishes.
The purpose of this invention is to provide a kind of method that is used to control loom, wherein yarn arrives the shed open end with a low velocity at the reproducible time point of an expectation.For realizing this purpose, the method according to this invention is characterised in that ideal time that yarn end arrives the shed open end serves as that the basis is determined with the revolution of loom,
Afterwards, after weaving process begins, determine that in such a way inserting the starting stage at weft yarn sends the perfect medium pulse of yarn to by main ejector, make yarn end with a specific ideal velocity above-mentioned ideal time point arrive the shed open end;
Wherein with shed open in the detection of a plurality of positions desirable times of advent of interrelating carry out in above-mentioned a plurality of positions, derive in view of the above for ideal position-time chart of carrying by the yarn of shed open;
When each weft yarn inserts in weaving process afterwards in above-mentioned some positions to detecting the time of advent of yarn end, then should the time compare definite desirable time of advent that interrelates with above-mentioned some positions with the front;
Afterwards, difference is arranged, then the medium pulse that sends yarn in the main ejector to is adjusted, make all or part of elimination of measured difference if detect between measured time and ideal time.
Use the method according to this invention like this, determined that at first yarn end arrives the ideal time of shed open end.In fact the above-mentioned time close the time point of closing the shed corresponding to loom.At this time point, weft yarn must arrive the shed open end.If weft yarn arrives evening, then it also can not pass whole shed open, produces float.Arrival itself early is not very serious problem, but expression yarn arrival rate is too high.Said as the front, in fact must overlap with the shed open close moment the desirable time of advent, but in view of the inevitable minor variations time of advent that takes place in some weft yarn insertion process, will be a point before shed open is closed slightly the desirable time of advent.After determining the desirable time of advent, determine that in such a way inserting the starting stage at weft yarn sends the perfect medium pulse of yarn to by main ejector, realize the desirable time of advent expected and desirable low velocity with above-mentioned perfect medium pulse.Although above-mentioned perfect medium pulse itself can be calculated in theory, but above-mentioned perfect medium pulse is definite in an iterative process according to another embodiment of the inventive method, wherein begin with the highest medium pulse that allows according to yarn strength, determine the mean pulse time that yarn arrives at desirable time point, determine the variation of the time of advent afterwards, if above-mentioned variation is greater than desired value, then reduce pulse height and prolong the burst length, arrive at desirable time point once more fifty-fifty up to yarn, determine the variation of the time of advent afterwards once more, continue this process, up to finding the pulse height that yarn arrived in ideal time and the combination in burst length, and have the variation of not half.Obtained the perfect medium pulse by this way, wherein yarn is put in above-mentioned correct ideal time with a desirable low velocity and is arrived the shed open end.Then the desirable time of advent that a plurality of positions interrelate in above-mentioned a plurality of position probing and shed open, write down these times then, derive ideal position-time chart in view of the above for the yarn of process shed open.In some cases, can also finish the said process of determining the perfect medium pulse in such a way, promptly bring into use a low medium pulse, afterwards by adjusting the height and/or the duration of pulse, arrive a kind of state, wherein yarn end arrives the shed open end in orthochronous once more, and variation simultaneously remains on very little.Insert for every next weft yarn in the weaving process afterwards, will compare with the desirable time of advent that the front is determined in the time of advent of above-mentioned some position measurements; Afterwards,, then in such a way the medium pulse that sends yarn in the main ejector to is changed, measured difference is eliminated when detecting when between measured time and ideal time difference being arranged.
The difference that is detected can be to make to be later than ideal time detection time.Therefore this means that the speed of yarn is low excessively.In order to correct this phenomenon, must improve yarn end speed.This can only finish by transmitting other medium pulse in the residing position of yarn end to yarn end with other injector.Therefore this makes structure complicated more.For fear of this situation, another advantageous embodiment is characterised in that, the medium pulse that sends medium in the starting stage that weft yarn inserts in main ejector to is selected like this, make above-mentioned pulse greater than the perfect medium pulse, afterwards, if detect between measured yarn speed and the ideal yarn speed difference is arranged, then by reducing the medium pulse that medium is fed to the time of injector and/or reduces to be sent to yarn by the pressure that reduces supplying media.Among this embodiment, the value that sends the medium pulse of yarn at first to is higher than the value of getting in touch with the perfect medium pulsion phase.The result is that the initial velocity of yarn will be higher than ideal velocity.As a result, yarn end will arrive the ad-hoc location in the shed open quickly than the speed by ideal position-time chart regulation.This difference will be come out by sensor, afterwards minimizing will be fed to the medium pulse of injector.Yarn will be braked in the process of shed open is passed in its flight more powerfully as a result, thereby speed will be reduced to such degree, and promptly it is corresponding to the speed that interrelates with ideal position-time chart.In this way, yarn with in fact in All Time constant minimum speed arrive the shed open end in the expected time.
Can arrive that the time point of some ad-hoc locations detects in the shed open to yarn end.For example by being arranged at the sensor in the shed open.Can also detect the particular measurement yarn line segment of process before yarn enters injector in addition, and therefrom derive the current location of yarn end in shed open.
If loom comprises that one has the yarn preparation facilities of a supply yarn storage cylinder, a plurality of coils of can reeling on this supply yarn storage cylinder, these coils can from above-mentioned yarn storage cylinder once more unwinding to be transported to loom, then according to another embodiment of the inventive method, can detect the time that yarn end arrives ad-hoc location in the shed open by a coil counter, this coil counter detects the coil of unwinding, and determine that on its basis each coil leaves the time point of yarn storage cylinder, on the basis of coil of yarn storage cylinder is left in detection, determine the position of yarn end in shed open on the time point of certain coil unwinding afterwards, and the time point that leaves yarn storage cylinder with coil is as the time that arrives ad-hoc location in the shed open.In this way, can also not use the sensor that is arranged in the shed open and determine that accurately yarn end arrives the time point of ad-hoc location in the shed open.
In the description of drawings below loom and method are described in more detail now.
Fig. 1 schematically shows according to a loom of the present invention.
Fig. 2 illustrates the example of one position-time chart, and yarn is according to the shed open of this chart conveying by loom.
Among Fig. 1, numeral 1 schematically shows the shed open of loom.Numeral 2 expression main ejectors, weft yarn 3 is fed to the one side, and pressure medium is fed to above-mentioned main ejector opposite side by pipeline 4 simultaneously.From the yarn storage cylinder 5 of a plurality of coils 6 of reeling of a yarn preparation facilities with yarn 3 unwindings.Also have a coil counter 7 on the yarn storage cylinder 5, this coil counter detects it when coil leaves yarn storage cylinder 5.Also be provided with a brake apparatus 8 (schematically showing), be used for when yarn arrives shed open decline, yarn being braked.Coil counter 7 connects with an electronic installation 10 by a signal pipe line 9, and the signal that on behalf of coil 6, coil counter 7 will leave the time of yarn storage cylinder flows to this electronic installation 10.
Be used for connecting with valve 11 and 12 by suitable pipeline, and may connect with a plurality of other valves 13,14 etc. to the supply line 4 of main ejector 2 supplying medias.Valve 11-14 connects with pressure-reducing valve 11 '-14 ' again, and pressure-reducing valve 11 '-14 ' is connected to a main supply line 15 that is used for the supplied with pressurized medium.In the device operating process, in the starting stage that weft yarn inserts, at least one among the valve 11-14 will be opened, and pressure medium is fed to main ejector 4 at least, and the result is left behind yarn 3 from yarn storage cylinder 5, and it is carried by shed open 1.Thereby just detect coil from yarn storage cylinder 5 unwindings by coil counter 7, and the signal 9 that will represent each coil to leave the time of yarn storage cylinder is sent to electronic installation 10.Represented a specific yarn line segment by each coil of unwinding, thereby coil is known the position of yarn front end in shed open during at every turn by unwinding.This shows on the horizontal axis of position-time chart of Fig. 2.Wherein supposition needs 8 coils to be used for spanning shed open on the shed open total length in this case.When unwinding coil 1, the front end of yarn is positioned at position 1, or the like, up to the last coil of unwinding, the yarn front end arrives the end 8 of shed open.
Medium under the high pressure is transported to principal pressure pipeline 15 by not shown device.Above-mentioned medium is fed to valve 11 and 12 by pressure-reducing valve 11 ' and 12 ', wherein regulates a specified pressure P1 in valve 11, regulates a lower pressure P2 in valve 12.In present device, at first determine that at preparatory phase yarn end arrives the ideal time point of shed open 1 end.Ideally above-mentioned time point overlaps with the time point that shed open is closed.Above-mentioned time point is by numeral 8 expressions among Fig. 2.By valve 11-14 one medium pulse is transported to injector 2 then, weft yarn is transported to shed open as a result, and the time that yarn end arrives the shed open end is detected.If above-mentioned asynchronism(-nization) in ideal time 8, then changes the medium pulse by valve 11-14, up to realizing that yarn arrives the terminal this state of shed open in the time 8.In this state, yarn will accurately move through shed open with this speed, thereby yarn will insert at weft yarn and begin to pass whole shed open in the time period between finishing.In this state, can determine desirable position-time chart, and the whole curves among Fig. 2.Can also determine the ideal time that yarn must in-position 1-8 (representing on the horizontal axis in Fig. 2) in this way.In weaving process, the time that yarn end arrives above-mentioned position 1-8 in the weft yarn insertion process can compare with the ideal time of being represented by the point on desirable (all) curves.
The time that yarn end arrives each position obtains from coil counter 7.Above-mentioned coil counter is counted continuous coil, and detects each coil by the time of unwinding.Leave each coil of yarn storage cylinder and represent a specific yarn line segment or a length of yarn, thereby can accurately know the exact position of yarn front end in shed open, for example after first coil, be positioned at position 1, after second coil, be positioned at position 2, or the like.Owing to also write down time of each coil unwinding, the above-mentioned unwinding time is also corresponding to the time that arrives position 1,2 etc.These data are sent to electronic installation 10 by a holding wire 9, the above-mentioned data of electronic installation 10 record, and with current time of in- position 1,2 etc. with meet Fig. 2 in desirable time of advent of ideal position-time chart compare.
In the normal use of device, a medium pulse is sent to injector 2 by valve 11, and this pulse is greater than with the required medium pulse of ideal velocity delivered yarn.Consequently the starting velocity of yarn is too high, and the result will follow curve 8 among Fig. 2 at the starting stage yarn at least ".According to control method, for example will be 3 confirm that yarn has arrived above-mentioned position 3 prematurely in the position.In order to correct this situation,,, reduce the medium pulse of arrival injector 2 perhaps by shut off valve under a lower pressure 11 with open the pressure that valve 12 reduces institute's supplying media by quick closing valve 11.Reduced yarn speed by this way, above-mentioned speed will no longer be followed curve 8 ", but as the curve 8 of ideal curve.Can several position or in whole positions to comparing the current time of advent and ideal time, as not simultaneously directly the medium supply of subtend injector adjust.Guaranteed that in this way yarn all arrives the shed open end according to desirable position-time chart in the correct time in All Time.Not only the time of advent all identical in All Time, and arrival rate is also lower very ideally, will consider certainly owing to the little difference of the reason of nature always can take place.
Although above-mentioned explanation is based on such a case, promptly employed initial yarn speed is higher than the yarn speed according to desirable position-time chart, also can be to use the situation of low initial speed.Consequently will follow curve 8 ' time of advent in position-time chart among Fig. 2, promptly be higher than ideal time 8.This difference will must be quickened the yarn in the shed open afterwards in stage detection early.This can not realize by the supply that increases medium, because send the speed that the pulse of yarn in the injector 2 no longer can influence the yarn front end to but in this case.In order to quicken the yarn front end, all are identical in this case, injection apparatus also need be set in shed open be used for a pulse is sent to above-mentioned front end.
Although in aforementioned, used the coil counter to detect the time that yarn arrives ad-hoc location in the shed open, also can use the timer that is arranged in the shed open self in some cases.But this can make structure complicated more.
Except using the coil counter to detect the time of ad-hoc location in the yarn arrival shed open, can also use one or more sensors that are arranged on the main ejector front portion, these sensors detect the yarn line segment of the special measurement of process, can derive the time that yarn end arrives ad-hoc location in the shed open with the employed same way as of coil counter by this information.
