Description
Technical field
The present invention relates to a kind of method that is used for determining the yarn qualities parameter, this yarn is produced at the workstation place of weaving loom and is reeled and form cross winding bobbin.The weaving loom of such production cross winding bobbin, and all is described in detail in many patents by known with various embodiments.
Background technology
For example described the beginning rotor spinner in DE 101 39 075 A1, this spinning machine has a plurality of similar workstations in a row disposed adjacent one another.Produce yarn at each place, station that works independently, this yarn is reeled subsequently so that form cross winding bobbin.For this reason, workstation has spinning mechanism and winding mechanism respectively.In addition, the workstation of these weaving looms also has yarn pulling device and suction nozzle.The workstation of this known weaving loom is configured to integral body, and each workstation all can be operated independently.
Described a kind of method and mechanism that is used to check yarn qualities in DE 198 41 604 A1, described yarn is produced at the place, spinning station of the weaving loom of producing cross winding bobbin.
Yarn is drawn to here and is subjected to tearing test by automatic drag-over unit from cross winding bobbin, described cross winding bobbin is maintained on the creel stand of workstation of the weaving loom of producing cross winding bobbin.For this reason, existing mechanism has yarn maintaining body, thread tension device and measuring head.Automatically drag-over unit is initially searched the yarn and thread head that runs on the cross winding bobbin with its suction nozzle and is pivoted downwards with the yarn and thread head that grasps.Therefore, cross winding bobbin is braked, and is drawn on the measuring head that is integrated in the automatic drag-over unit by the yarn suction nozzle of automatic drag-over unit from the yarn pile of cross winding bobbin unwinding.In this case, measuring head detects yarn tension, this yarn tension of indication in relevant indication mechanism.In the moment that yarn is torn, yarn tension jumps back to zero suddenly.The proportional relation of the tear strength of the size of the yarn tension of Que Dinging and yarn by this way.
The device that also known and automatic cross traverse winding machine is associated from patent documentation DE 39 36 517 C2, this device allows to monitor the service ability of the Yarn Connecting apparatus in each the winding head zone that is arranged in this weaving loom.This known device also is arranged to and can moves and can be one after the other at the winding head place of respectively expecting of sutomatic winding machine the service ability of the Yarn Connecting apparatus that is installed in this be monitored along each workstation.
Yet as mentioned above, this well known device can only one after the other be checked the Yarn Connecting apparatus of winding head.This means, if a workstation place monitors Yarn Connecting apparatus therein, then can only when having finished the automatic monitoring at the first workstation place and be linked to new workstation once more, this device could begin another Yarn Connecting apparatus is monitored.Thereby can not monitor simultaneously the Yarn Connecting apparatus of a plurality of workstations.
In addition, known movable device is relative complex also, thereby relatively more expensive on mechanical realization.
Each winding head that device that (DE 40 04 755 C2) will be used for monitoring the service ability of Yarn Connecting apparatus directly is integrated into automatic cross traverse winding machine has been proposed.The method of describing in DE 40 04 755C2 is for example stipulated, the service ability of the single Yarn Connecting apparatus of running check wherein applies predetermined tension on the yarn that engages in the Yarn Connecting apparatus of these in winding head.For this reason, cross winding bobbin slowly rotates along coiling direction by the traversing roller of winding head, and yarn is fixed simultaneously by the yarn stretcher of winding head.In other words, effect has adjustable test tension force on yarn, and thereby on the yarn tie point effect adjustable test tension force is arranged.
If fracture occurs in the yarn join domain in this process, then this illustrates that all the yarn engagement device of being checked suitably do not work in many cases.
Summary of the invention
From above-mentioned prior art, the objective of the invention is to propose a kind of method that allows directly to determine the yarn qualities parameter at the workstation place of Offenend-spinnvorrichtung.Specifically, place, the work on hand station of the beginning rotor spinner that can describe in DE 10,139 075 A1 carries out this method.
According to the present invention, described purpose realizes that by a kind of method this method is carried out according to the method step of describing in the claim 1.
The favourable embodiment of the method according to this invention is the theme of dependent claims.
In the method according to the invention, in first method step, the yarn that will produce on Offenend-spinnvorrichtung and be wound on the cross winding bobbin is fetched and is placed on the yarn pulling device at related work station from this cross winding bobbin.In other words, the yarn with examine temporarily is fixed in the yarn pulling device at first.In next method step, the electric drive by cross winding bobbin makes cross winding bobbin rotate along coiling direction, thereby (increasing gradually) tension force acts on the yarn.In the process that yarn tension increases, in the other method step, detect the electrical characteristics of the drive motor of cross winding bobbin simultaneously.
These electrical characteristics are preferably the corner of described motor rotor, the motor voltage and/or the motor current of coiling driver.Subsequently, utilize at least one in these electrical characteristics and consider that the count of yarn determines some mass parameter of yarn.For example, this can by mathematical function/computing, algorithm or by with relatively the carrying out of known measurement data or measurement data sequence.The yarn qualities parameter of determining for example is the tear strength of yarn and maximum yarn elongation.
As described in claim 2, described tension force is increased to the minimum tension that can be scheduled at least.Yet this yarn tension preferably as described in the claim 3, is increased to the generation yarn breakage.
According to claim 4, in case yarn has been placed on the yarn pulling device, cross winding bobbin just presses its drive drum by creel stand more and more intensified pressure.Contact pressure by the increase between cross winding bobbin and its drive drum can guarantee the driving to the essentially no slippage of cross winding bobbin.
In the further structure (claim 5) of this method, yarn remains between the carry-over pinch rolls and niproll of yarn pulling device, this yarn pulling device extracts yarn from spinning mechanism during normal running, perhaps after yarn interrupts yarn and thread head is fetched to be connected in the Offenend-spinnvorrichtung structure.
In this case, carry-over pinch rolls are braked by its driver, thereby yarn is remained between carry-over pinch rolls and the niproll reliably.In other words, utilize being frictionally engaged between carry-over pinch rolls and the niproll temporarily to keep yarn.In this case, yarn can carry out the powerful tension force that tear strength is tested all the time by clamping reliably thereby can apply on yarn.
In order to obtain the suitable measurement result of yarn qualities parameter, according to claim 6 regulation, the driven test speed of cross winding bobbin is starkly lower than the normal winding speed of cross winding bobbin.In other words, test speed be to the maximum cross winding bobbin normal winding speed 10%.Like this, can be slowly and increase the yarn tension that acts on the yarn constantly, up to reaching the minimum yarn tension that can be scheduled to or rupturing up to yarn.
In a preferred embodiment, described test speed keeps constant (claim 7).Thereby guarantee yarn tension continuing and pulsation-free mode increases, make measurement result can reappear and very accurate.
As described in claim 8, when carrying out the method according to this invention, utilize existing shut-down mechanism to detect the quality of yarn fluctuation.In other words, utilize shut-down mechanism to determine splicer, this splicer can be positioned in measure portion between yarn pulling device and the cross winding bobbin subsequently, and can also check their mass parameter.
As described in claim 9, advantageously store determined yarn qualities parameter.In other words, in a preferred embodiment, determined yarn qualities parameter is stored in the storer, this storer for example is arranged on the bobbin of cross winding bobbin or in the bobbin (claim 10).Like this, also can whenever determined yarn qualities parameter be assigned to relevant yarn in the future.
Such storer can be electronics, magnetic or optical memory.Shown in claim 11, verified so-called RFID label is favourable as the storer of the determined yarn qualities parameter of storage.
As already described above such, because directly with data storage on cross winding bobbin or in the cross winding bobbin, so can at any time read the determined mass parameter of the yarn that is wound on the cross winding bobbin reliably, after spinning machine is pulled down cross winding bobbin even also be like this.For example can during other processing of cross winding bobbin, read and estimate these data.
Such known RFID label itself can be arranged in the bobbin of cross winding bobbin for example and be protected.Such RFID label allows contactlessly to store determined mass parameter and reads these parameters in corresponding contactless mode.The transmission of information is undertaken by the radio device in such RFID label.
In order to ensure the precision of determined yarn qualities parameter, suitable is to repeat described method of testing (claim 12) on yarn repeatedly.In this case, can determine the number of times of repetition according to predetermined tolerance, wherein, for example, the measurement result of Que Dinging can differ less than 10% each other in succession, so that measurement result is considered to enough accurate.Obviously, in this case, this tolerance also can be fixed on 5% etc.For this method of testing, multiplicity that can pre-determined constant.Also can be by the precision of this measurement increase mass parameter relevant with yarn.
As claim 13 and 14 defineds, to implement economically technically in order to make described method, the open loop and/or the closed loop control algorithm that will be used for claimed method are stored in microprocessor, and this microprocessor for example is the parts of workstation computer.Like this, can turn back to the existing parts of spinning machine workstation economically.
Because relative air humidity can have considerable influence to the quality of yarn intensity that is spun into, so the present invention's regulation, also can synchronously determine relative humidity and store (claim 15) with the test of execution tear strength by measuring technique.Only can definitely compare determined each yarn qualities parameter by this measurement.
From following description, will embody other advantage of the present invention, feature and details, wherein describe embodiments of the present invention with reference to the accompanying drawings.

Fig. 1 represents the workstation1 of Offenend-spinnvorrichtung, and this workstation is configured to and can carries out the method according to this invention on this workstation.(therefore only schematically illustrated) as is known, such workstation1 also has Offenend-spinnvorrichtung structure 2 and winding mechanism 3.The yarn 9 that produces in Offenend-spinnvorrichtung structure 2 leaves Offenend-spinnvorrichtung structure 2 in normal spinning operating period of workstation1 by yarn traction tube 21.In other words, yarn 9 pumps out from Offenend-spinnvorrichtung structure 2 by means of the yarn traction tube 21 or the adapter piece 16 that are arranged in this zone by yarn pulling device 27.Arrive in the way of collecting device 3 at it, yarn 9 it is wound on the cross winding bobbin 8 that is driven in rotation by Yarn lateral-movement device 24 before, also pass through shut-down mechanism 26, thread storage device 60 and 61 and on cured device 62.
Here, cross winding bobbin 8 is preferably acted on its lateral surfaces in the mode that is frictionally engaged by drive drum 23, and drive drum 23 drives by reverse single driver 56.
Cross winding bobbin 8 is also rotatably remained in the winding mechanism 3 by the creel stand of installing pivotly 22.Here, can regulate contact pressure between drive drum 23 and the cross winding bobbin 8 by the moment of setting creel stand 22.
For the yarn 9 of reeling, for example, already mentioned Yarn lateral-movement device 24 is arranged in the zone of drive drum 23 in order to form cross winding bobbin 8, this drive drum 23 is driven by step motor 57.Centering Plate 17 with pivoted installation of yarn guide notch 18 can be arranged in the upstream of this Yarn lateral-movement device 24, and if necessary, this plate can be folded in the normal yarn operating path in the mode that limits by driver 55.
In workstation1, if there is the interference that for example causes owing to yarn breakage (for example detecting this yarn breakage by shut-down mechanism 26), then workstation computer 25 guarantees that the spinning mechanism 2 at related work station 1 and relevant winding mechanism 3 all stop.In other words, the single driver 56 of drive drum 23 is subjected to the effect of stalling current.
Be used for the open loop of various drivers of workstation1 and/or the workstation computer 25 of closed-loop control and be connected to these drivers by electric wire 65.
In order to eliminate interference (for example yarn breakage), at first pick up the yarn and thread head that runs on the cross winding bobbin 8 by suction nozzle 4.In other words,, on cross winding bobbin 8, seek, pick up yarn and thread head, and place it in the yarn pulling device 27, and penetrate in the adapter piece 16 at spinning station by suction nozzle 4; Described suction nozzle 4 can be regulated with limiting mode between yarn take-off location in winding mechanism 3 zones and the yarn delivering position in spinning mechanism 2 zones by step motor 6.In this case, the suction inlet 19 of the suction nozzle 4 by being subjected to the low pressure effect picks up yarn 9 from the surface of cross winding bobbin 8, is provided for guiding the yarn guide notch 20 of yarn 9 in the central authorities of suction inlet 19.Run to the process of yarn delivering position from its yarn take-off location at suction nozzle 4, picked yarn 9 slides along static Yarn guide device 5, catches in the profile 10 (it is in bottom-open) up to the yarn that finally slides into Yarn guide device 5.When suction nozzle 4 pivoted downwards, yarn 9 also penetrated in the function element of workstation1.In other words, yarn 9 also is placed in the yarn pulling device 27.And this yarn is sent to by yarn capturing element 7 in the zone of Offenend-spinnvorrichtung structure 2, and yarn and thread head is inhaled in yarn traction tube 21 or the joint member 16, and is connected to the fibrous ring (not shown) in this rotation in Offenend-spinnvorrichtung structure 2.
When carrying out the method according to this invention, the yarn of being fetched from cross winding bobbin 89 also at first is threaded into the yarn pulling device 27.
In other words, yarn 9 is positioned in the yarn pulling device 27, and this yarn pulling device 27 is between the niproll 64 of carry-over pinch rolls 63 that can be subjected to the electric notor effect and installation pivotly.In case yarn 9 has been placed in the yarn pulling device 27, niproll 64 just is switched to can be by the carry-over pinch rolls 63 of driver 59 drivings, thereby it is yarn 9 is clamped in the yarn pulling device 27 between carry-over pinch rolls 63 and niproll 64, and thereby yarn 9 is temporarily fixing.
The yarn 9 that is fixed is subjected to the tension force effect subsequently.In other words, single driver 56 makes cross winding bobbin 8 along the coiling direction rotation by means of drive drum 23, thereby guarantees that tension force acts on the yarn 9 that is fixed in the yarn pulling device, and this tension force finally causes yarn breakage in this preferred implementation.In 56 operating periods of driver, detect its electrical characteristics, for example the corner of motor rotor, motor voltage and/or motor current.Subsequently according at least one characteristic in the detected characteristic and consider that the count of yarn determines each mass parameter of yarn 9.
Startup of the method according to this invention and control, and utilize electrical characteristics to determining that the yarn qualities parameter is carried out, can be undertaken by computer program.This computer program for example can move on workstation computer 25.In this case, workstation computer 25 itself can be integrated in the network, thereby if necessary can be so that determined yarn qualities parameter also can be used for other position, to assess or to handle.
And, for example can determine thickness of yarn by shut-down mechanism 26, and thereby definite joint.In addition, humidity sensor advantageously is set determines relative air humidity, this relative air humidity plays important effect in determining the yarn qualities parameter.When determining mass parameter, preferably also in workstation computer 25, handle by shut-down mechanism 26 or by the humidity sensor established data.In favourable embodiment, determined yarn qualities parameter is stored in the storer, and this storer is arranged in the bobbin of cross winding bobbin 8 or on the bobbin.
Fig. 2 shows the process flow diagram that is used for method of testing according to of the present invention.
As shown in the figure, in first method step, at first yarn 9 is penetrated in the yarn pulling device 27 and also temporarily remain in this.Afterwards, preferred operation method step 2 and 3 simultaneously.In method step 2, cross winding bobbin 8 is driven device motor 56 and drives along coiling direction, thereby applies the tension force of expection in this process on yarn 9.In method step 3, side by side detect the electrical characteristics of drive motor 56 then.Preferred manner of execution step 2 and 3 is until yarn breakage takes place.Can see yarn breakage this moment, especially from the process of electrical characteristics.
In other words, when yarn breakage, for example, driver 56 required motor currents descend suddenly, and this clearly illustrates that yarn breakage takes place.
For example,, consider the count of yarn of yarn 9, can easily determine each mass parameter of yarn 9 from the electrical characteristics of detected driver 56 by the appropriate mathematical method.
The mass parameter of so determining can be stored in subsequently and be arranged in cross winding bobbin 8 or be arranged in storer on the cross winding bobbin 8.Thereby finished the actual test process that is used for determining mass parameter, and therefore finished the method that is used for determining mass parameter.
