Abstract
Optical system for controlling the unbroken condition of warp yarns in a weaving loom wherein on optical reading device is apt to detect a continuous succession of images of the warp yarns as a whole, or of a subset of the same, and a processing unit (U) is apt to measure in a continuous manner one or more parameters of each of said images. The processing unit (U) sends a stop command to the loom and an eventual alarm signal when one of said parameters relative to the last acquired image differs, by a pre-established quantity, from a predetermined value of said parameter or from the value of such parameter measured in one or more of the images preceding the last acquired image.
Description
The present invention relates to a kind of optical system of controlling warp thread in the loom.More specifically, the present invention relates to a kind of system that in weaving process, controls the situation that do not rupture of warp thread, be usually directed to, as the function of " Warp stop motions " and move as the industry in uninterrupted mode.
Warp stop motions is on a kind of loom that is installed in any kind of, be suitable in the process of weaving cotton cloth the device at warp break place, location rapidly, like this, just can stop loom immediately, the operator can repair described warp (that is, being tied a knot in the fracture termination of the above warp thread) before defective fabric produces.
In fact, warp break causes the variation of the optimum tension of warp described in the weaving process through regular meeting, and, unacceptable flaw on the fabric that described lax (perhaps, under the worst possible situation, or even hand pick) can obviously cause being produced.
Existing weaving technology uses two kinds of main devices with the check warp thread.More first of wide-scale distribution type is used the menopause tablet Warp stop motions, on the contrary, use once in a while and second type of only being used for very simple, low-quality product use the rotating brush Warp stop motions.The main device of these two kinds control warps will briefly be shown.
The menopause tablet Warp stop motions is furnished with a plurality of thin steel blades, and they are regarded as " menopause tablet " usually.Each blade is centered around the warp yarn top, and thus, because loom imposes on the tension force of warp thread, menopause tablet is raised to be called as above the transverse bar of " bank ".Each bank-in fact, in a loom, have usually two conductions of several parallel banks-be furnished with, the element of metal normally, described element has the shell in U type cross section to constitute by an interior bar and one, described conductor dbus is crossed one deck insulating material film, and is isolated mutually with an electric contact.Two bank conductors link to each other with an electric control loop, like this, no matter when when a warp break or when lax, no longer the respective drop wire that is supported by yarn tension is fallen and is put on the bank last, and has closed the electric loop that two conductor elements by bank form.When menopause tablet one falls, a relative electronic-controlled installation is checked loom at once, simultaneously, sends warning signal and points out that menopause tablet drops on the signal of which bank to the operator, sometimes, even can also point out the general place that falls.
The menopause tablet Warp stop motions has the advantage of immediate intervention when warp break usually, and still, this device also has some shortcomings.At first, this device needs the very long set-up time, and on thousands of warp thread that form warp, each root all needs to insert a menopause tablet.The bigger factory of weaving usually can be for this operation be equipped with special automated machine, and still, under any circumstance, this all is a kind of complexity, the very long also very high operation of therefore cost.
Although since be installed in menopause tablet quantity on the bank huge-thousands of or up to ten thousand usually-designed a large amount of electronics or mechanical device to simplify this task, seek the menopause tablet that falls and require the operator to possess professional skill and one period long operating time of certain level usually.
In addition, because the friction to menopause tablet that warp thread causes can cause the wearing and tearing of menopause tablet, menopause tablet will regularly replace, especially when using the warp thread of high frictional force.In addition, when using meticulous synthetic threads, for example, those are used for the warp thread of high-quality lining, organza or similar products especially, and menopause tablet also can cause same damage to the friction of yarn, and this can cause the fracture of yarn.
Another defective stops to show that by the mistake of loom this defective is particularly evident when knitting meticulous yarn, requires the tension force of warp thread low at that time.In fact, in these cases, because warp thread have a rhythm motion, the typical vibration of menopause tablet sometimes might be enough wide contacts the mistake of bank causing, result even need not warp break or relax loom is stopped.
Because the pack of electrostatic charge on warp thread, similar defective can take place equally, that is, and owing to the bank control loop sends the shutdown that signal causes misconnection to be touched causing loom.Because the friction of warp thread on menopause tablet can cause the pack of electrostatic charge on warp thread, this is especially obvious when weaving synthetic threads.Described electrostatic charge pack can cause discharging on bank aperiodically.This electric current meeting temporary close bank circuit, and the interim mistake indication that produces warp break thus.
The another kind of defective that static on warp thread load pack also causes the menopause tablet Warp stop motions to show, that is, and the static adhesion of or several warp thread.In fact, the static adhesion strength is enough to surpass the weight of menopause tablet sometimes so that even take place at a warp thread under the situation of place fracture, relevant menopause tablet is caught by adjacent yarn, and fracture is not detected.
(shown in Fig. 2,3) rotating brush Warp stop motions comprises a kind of device G that laterally is positioned at below the warp thread, this device comprise a kind of linear scrub-brush C and a kind of with the hairbrush C position harmonic wave warp thread D that is stretched of relative position radially, this hairbrush C continues low speed rotation, regularly brushes warp thread.When a warp break, hairbrush C can " catch " this warp thread when rotated, and pulls it by the warp thread that ruptures round the rotating shaft winding of device G.In the irregular movement of fracture warp thread E, yarn itself has applied a kind of progressive pressure to harmonic wave warp thread D, so that described warp thread forms the shape of distortion as shown in Figure 3A, and therefore activates the traction contact H that stops loom by shortening.
The rotating brush Warp stop motions provides the advantage of avoiding menopause tablet and related defects together to occur, but but has the big disadvantage that can't in time send the yarn breakage signal.This signal is actually and has postponed, and depends on the relative position of warp break hairbrush that time with respect to warp thread.Therefore, may occur that promptly after the warp break, only loom just stops behind tens of routings, so just on fabric, cause obvious and serious flaw.
The improvement of this Warp stop motions by using brush the anharmonic wave warp thread and a kind of can faster interception and accurately the ray of the Optical devices of the location brush fracture warp thread of catching for example photoelectric tube or laser obtain.Even in this improved Warp stop motions, although degree can be lightly, but indication and the corresponding delay issue that stops loom still existing, so that the hairbrush Warp stop motions is weaved those for example less demanding products of fabric quality such as lining as being specifically designed to with once mentioning.
Therefore, the purpose of this invention is to provide a kind of novel optical system that is used to control the situation that do not rupture of warp thread on the loom, this system can indicate the fracture of warp thread rapidly or relax, like this to avoid occurring any warp flaw on the fabric, and the major defect of the menopause tablet Warp stop motions of discussing more than eliminating, promptly, set-up time is long, menopause tablet weares and teares, warp thread damages, the warp break signal of mistake, perhaps, on the other hand, because the static adherent phenomenon between the warp thread causes the index signal of not sending described fracture.
Especially, a free-revving engine of the present invention is the existence of eliminating the metal menopause tablet that is associated with each root warp thread.By this way, not only the very long initial stage installation steps of warp and also since the negative consequences that the physical friction contact between menopause tablet and the warp thread causes can be eliminated automatically.
A kind of such warp control system will meet the height requirement of the industry, until today, this demand also is not suggested, in other words, compare with the menopause tablet Warp stop motions, have the Warp stop motions that has same efficient in the context of detection that ruptures fast, the running cost of this device is lower, and significantly reduce the total degree that stops loom, just done as the hairbrush Warp stop motions.
Can realize this purpose by a kind of optical system of controlling the situation that do not rupture of warp thread in the loom according to the present invention.Described in the feature of this system such as the following claims 1.
In any case, the present invention will by following some as shown in drawings preferred embodiment description and understood better.Wherein:
Fig. 1 is a kind of schematic side view of loom, wherein, has inserted the schematic block diagram according to the optical system of the situation that do not rupture of control warp thread of the present invention;
Fig. 2 A is a kind of front view of brush Warp stop motions of prior art;
Fig. 2 B is the side view of the Warp stop motions of Fig. 2 A, and this device is inserted between the loom critical piece of its work.
Fig. 3 A and 3B are the views in the warp thread process of detection of broken corresponding to Fig. 2 A and Fig. 2 B.
In Fig. 1, the direction that is woven along fabric is followed successively by: through the fabric reel R of axle S, warp thread cylinder F, warp thread O, heald frame Q, comb (comb) P and Woven fabric T.The basic principle of innovation according to the present invention, the do not rupture control of situation of warp thread obtains like this, promptly by a kind of optical reader 1 whole subsystem image of checking through Yarn image or this warp thread, and handle the image that described reader obtains by processing unit U by rights.This processing unit U can be the identical processing unit that is used to control the loom operation at present.
Preferably, optical reader 1 is installed in the top, plane that warp thread O forms, and so just obtains the plane of this warp thread, in other words, is all apparent images of all warp thread of a width of cloth.Image definition can increase the contrast between warp thread O and the background of image own like this by improving corresponding to optical reader and at a kind of light source L of the couple positioned opposite of warp thread O in obtaining image.As mentioned above, the image that obtains can comprise the subsystem of whole warp thread or this warp thread; Under latter event, that is, when the coverage of optical reader 1 does not comprise all warp thread, monitoring fully by the optical reader that uses several suitable biasings of all warp thread finished.
Optical reader can be a type, and for example video camera also can be linear, for example is used for the continuous grizzly bar of optical reader (bar) of scanner.
The optimum position of optical reader and relevant source is installed, and particularly from mechanical angle, is position as shown in the figure,, along the fabric movement direction, tightly is positioned at the upstream of heald frame group that is; This zone does not in fact fully have other service units and other loom annexes.In this zone, owing to be used to form the heald frame Q of shed open, warp thread can regularly separate at full tilt, but this can't constitute any problem.In fact, at first can make the image taking time consistent with the shed open shut-in time, this moment, warp thread O can all very well align.Randomly, can freely select the image taking time by the depth of field of suitable adjusting optical reader, especially when preferably making the image taking frequency be higher than the loom beating-up frequency.
The position of optical reader 1 is not critical to operation of the present invention.When weaving or reason is installed when such requirement arranged, also might optical reader be installed in other positions.Shown in addition two kinds of installation sites that optical reader is possible in the drawings: position 2, tightly be positioned at warp cylinder F downstream, position 3 tightly is positioned at the upstream of comb P.
The image of warp thread O passes through optical reader, obtain according to the order of sequence with the minimum frequency identical with the loom operating frequency, if detect the flaw of warp like this, loom stops in beating up first or the second time after detecting flaw the latest, therefore, after finally having carried out the reverse loom beating-up of respective numbers, flaw can be eliminated rapidly.
According to the present invention, one or several image parameter of image by measuring last acquisition and by described each parameter is compared with the preset value of this parameter or with image that this parameter in the end obtains before one or several images in value compare, thereby make processing unit U detect the existence of warp flaw, for example warp break or lax.
In first embodiment, the parameter of consideration is the quantity of warp thread.Processing unit U obtains the quantity of calculating warp thread on the image at optical reader 1, should calculate gained result and preset value then relatively, in this case, preset value be mounted on the loom the warp thread sum (perhaps, if this image does not comprise all warp thread, then be on the image shown in the warp sum of warp thread group).The weaving worker can know the preset value of warp thread quantity, he can be manually with this numerical value input processing unit U, perhaps processing unit itself can just begin in the program of weaving, preferably when loom pauses, promptly, when all warp thread are also intact and when not rupturing, use according to the result of the image calculation that obtains for the first time.
In the process of analyzing the last image that obtains, by predefined numerical value, it is different with above-mentioned preset value that processing unit detects the number of warp thread, and it just sends halt instruction to loom leading engine M, simultaneously, send alarm signal A need carry out loom with prompting weaving worker manual reparation operation.The above-mentioned predefined numerical value that the alarming device newspaper is rung is generally equal to 1.
In the second embodiment of the present invention, the parameter of consideration is the global pattern that the warp thread of the image that obtains forms.In this case, the image that pixel of pixel of processing unit U ground will obtain at last and and then the image before this last image or at last the image that obtains of the mean value of the N that obtains image compare, this just can stop loom when only the pixel deviation quantity between two width of cloth images is higher than predefined numerical value.In this case, to have to determine this predefined numerical value according to the warp thread type of using and other weaving conditions experimentally, especially, this numerical value will have to enough highly may carry out small size lateral movement and cause the caution situation to get rid of warp thread, and will enough hang down to allow sending signal owing to warp break or the warp thread deviation that forms that relaxes.
Therefore should consider that according to the present invention, by the metal menopause tablet of the traditional Warp stop motions of thorough elimination, all correspondingly are eliminated too by the electrostatic phenomenon that friction between warp thread and this type of menopause tablet causes.Therefore, significantly, under warp break or lax situation, and compare on the loom that uses traditional menopause tablet Warp stop motions, described warp thread will make the layout that oneself places more changeable shape.
In the 3rd embodiment according to the optics control system of warp thread of the present invention, the parameter of consideration is the depth of parallelism of warp thread.Therefore, compared with the position of the desirable warp thread of laying according to preset direction in the position of detected each warp thread in the image, determine the deviation between two images.Can be with the manual input processing unit U of preset direction; On the contrary, preset direction also can be according to loom warp thread direction during pause and being detected automatically by processing unit before beginning to weave operation.
Can for example be pixel percentage by only when described percent value is lower than predefined numerical value, just stopping loom along all warp yarn images of preestablishing direction alignment with deviation calculation.Even will having to according to type of weave and condition, described predefined numerical value determines experimentally, and will have to enough high to get rid of because the motion of heald frame makes warp thread produce the rub-out signal that small angle variation causes, and enough low to comprise because warp thread is lax or rupture and make warp thread generation and all possible deviation of described preset direction.
In the 4th embodiment, the parameter of considering is the position of each warp thread, because represent the pixel quantity of all warp yarn inconsistent with the quantity in the former image, by detecting the deviation between two width of cloth images, compared with the position of same warp thread in the former image in this position, perhaps with last N time before the image of average data formation of image in same warp thread position compare.For the fracture that makes warp thread or lax easier from possible by detecting small size lateral movement of normally weaving the described warp thread that operation causes and the small-angle movement, when the lateral distance of yarn position is bigger in respect to previous image, or when deviation be bilateral rather than when one-sided, can make the weight of deviation of each single pixel bigger.
Determining of the default amount of deflection of the hold function of loom and this hold function of decision is similar to the description among above-mentioned the 3rd embodiment, for for purpose of brevity, is not described further herein.
Different with second embodiment, the loom halt instruction among third and fourth embodiment is just to send with respect to the deviation of the preset value of measuring according to each warp yarn rather than obtain the deviation of preset value of image measurements according to all after confirming.Therefore, in these embodiments, owing to weave operation normally and, may distinguish the small size motion of warp thread usually with higher accuracy by warp thread fracture itself or the lax bigger motion that causes.
The 5th and last embodiment in, at present preferably, the parameter of consideration is the theoretical diameter of warp thread.In this case, use has the grid type linear optics reader (bar linear optical reader) of high quantity optical reader, resolution ratio equates with the theoretical diameter of warp thread at least like this, preferably 1/2 of this theoretical diameter, even be 1/4 better.In fact the optical reader of the type not only can detect the existence or the disappearance of warp thread, can also detect progressive attenuating-when fracture be not to take place suddenly but because during the progressive wearing and tearing of warp thread-signal by prediction error and stopping with respect to the loom of rhegmagenesis.
Should be understood that the present invention describes by some preferred embodiment especially, the target of these embodiment is the indication of some possible working method of the present invention, needn't think that the present invention is limited to these embodiment.Therefore, should predict other possible embodiment, in these embodiments, need not to break away from the scope of the invention that limits as appended claims and will be more suitable for single application-specific or the combination more practical to single application-specific according to being considered to based on each situation, above-mentioned parameter can carry out diversified merging or substitute with other parameters merging or by other parameters.
