Description
Technical field
The present invention relates to a kind of weaving loom, especially bobbin winder, it has a large amount of station, and these stations have the functional device for executable operations function; For the device at production period monitoring production process; And device, they are for determining the deviation between desired production process.
Background technology
EP 0 685 580 Bl discloses this weaving loom, and it is for determining the flaw in the yarn, rove and the webbing that are caused by production reason.In a first step, use-case in this way the part of clearing equipment sensor detect produce in fault.Measured value compares with one or more threshold value, and sorts out in classification district.By classification, district obtains fault sample, can by it compared with modeled predetermined reference sample, and these reference samples can infer the reason causing detected fault.The measured value that solution disclosed in EP 0 685 580 Bl relates to production period detects carries out statistical analysis.But can not determine all failure causes for a long time by this way.Must produce in defectiveness mode in certain hour in addition, to determine failure cause.
DE 39 17 055 A1 discloses a kind of device, and it is for monitoring the reel for yarn of the coiler device of the weaving loom manufacturing cross winding bobbin around production process.At this, be not monitoring product to determine failure cause, but analyze manufacturing parameter, monitor traversing amplitude and/or frequency of transverse moving in this case.But some failure cause can only be detected at this, such as yarn tensioner or cylinder fault.
DE 40 31 419 A1 discloses a kind of weaving loom, especially bobbin winder, and it has a large amount of station, these stations have the functional device of executable operations function, wherein, to the central control unit that these work position distributions are common, this central control unit has operating means and display unit.DE 40 31 419 A1 discloses a kind of automatic winder, and it has multiple winder station be arranged side by side.When weaving loom or its control unit detect abnormal condition, just show this abnormal condition to operator.In order to analysis of failure, operator can manual actuation station slow testing process and range estimation monitoring flow process.By this way, operator can determine possible failure cause based on its professional knowledge, or in maintenance span, check that whether weaving loom is working properly.The control device of weaving loom can input required maintenance work and corresponding service intervals.Executed work can be inputted in addition on control device.Can simply check whether and when perform some work by this way.In these maintenance works, such as, checked by visual inspection n-back test, cleaning function element, lubrication movable part or preventive replacement function element.
DE 602 19 260 T2 discloses a kind of bobbin winder, and wherein each winder station can check especially by estimating individually.For this reason, operator must activate checking mode and specify the station that will check on equipment control device.Afterwards, operator goes to corresponding station and activates invalidating switch.Such operator directly can perform inspection on station.
With regard to the work according to DE 40 31 419 A1 or DE 602 19 260 T2, always need have to corresponding weaving loom the personnel that the technical ability of accurately understanding is higher.In addition, when station quantity is more, on each station, visual inspection individual inspiration is in other words quite complicated and consuming time.
Undocumented DE 10 2,010 034 971 A1 is based on the weaving loom according to DE 40 31 419 A1, especially bobbin winder, it has a large amount of station, these stations have the functional device of executable operations function, wherein, be furnished with common central control unit to these stations, this central control unit has operating means and display unit.In order to be reduced at looking up the fault and execution maintenance work on weaving loom, a station can perform the flow process of automatic inspection functional device, time disconnected aborning, the flow process of at least one functional device that utilize the operating means of central control unit to trigger previously to have determined, automatic inspection station.Be provided with the device for result being transferred to central control unit, and check result can be read in central control unit display unit.

Operating means can be utilized to make a reservation for the station that will check according to an embodiment.Can make a reservation for check all stations of weaving loom.But also can only check a part of station.Such as, when when this part station is shut down, other part stations continue to produce, this is significant.Also can check targetedly and show abnormal station at production period.
Operating means can be utilized to trigger the inspection of these predetermined stations simultaneously.That is, executed in parallel is to the automatic inspection of these predetermined stations.Can guarantee by this way fast and effeciently to safeguard.
Other embodiments disclosed in DE 10 2,010 034 971 A1, can utilize operating means to trigger the flow process of multiple equipments that previously determined, automatic inspection station.Button thus, especially simplifies inspection for the personnel that qualification is more shallow, this is because can be utilized to a certain extent to check multiple functional device.Operator not necessarily oneself have to select the functional device belonging to this flow process.At this, the flow process triggered can trigger overall inspection, or a part for only audit function device.At least one functional device that will check can utilize operating means to make a reservation for.Thus individual inspiration can be realized.
According to advantageous manner, the function group that will check can be selected to these functional device distribution function groups of station.Especially, when production is about this function group extremely, operator can use this option.Central control unit can show these extremely based on automatic analysis creation data, or identifies that these are abnormal by the specialty observation of operator.
Check result can illustrate on the display apparatus as text.That is, the correlated phenomena be defined is described with written form.This display provides understandable information.Do not need the implication of searching signal or code in handbook.
Utilize the solution of DE 10 2,010 034 971 A1 can obtain gratifyingly safeguarding result.But when there is abnormal and fault during the technological process of production, this solution only provides very limited help to non-specialist operators.Although the deviation that display production period occurs, but operator can only determine alone deviation about each functional device and test it targetedly.The professional knowledge relating to operating personnel is analyzed in execution error.Only remain outside conventional maintenance for non-specialist operators, perform the possibility of all functions device to test flow process.This means to need the plenty of time.Can not produce during this period, thus reduce productivity.
Summary of the invention
Based on weaving loom disclosed in EP 0 685 580 Bl, wherein, there is the device of the production process of monitoring production period and determine the device of the deviation between desired production process, task of the present invention is, improve the detection to the fault formed by the deviation in production process, realize fast and determine the reason of the deviation caused between production process and desired production process as far as possible exactly.
In order to solve this task, station can perform the flow process of automatic inspection functional device, and when setting device is used for breaking aborning, previously determined according to determined deviation trigger, for the flow process of at least one functional device of automatic inspection station, wherein, be provided with display unit and the device for check result being transferred to described display unit, to illustrate check result on said display means.
In weaving loom of the present invention, when there is deviation between production process and desirable production process, automatic start-up check.The flow process performed to check is relevant with Deviation Type.That is, some functional device that may be relevant with deviation is checked targetedly.Result can show to operator, and by it fast and be supplied to operator without loss in productivity.
Produce intercourse and perform inspection.Production interruption can be carried out targetedly, or can wait until and normally produce interruption next time.Specific practice can depending on Deviation Type.(such as produce product and have substandard products) in the larger situation of deviation, originally also can breaks in production.If desired, can inspection be triggered at once by machine and directly result is supplied to operator.Like this can fast detecting failure.When deviation is not serious, triggers when upper once production interruption and check.In bobbin winder, such as broken yarn or more change of bobbins time occur that this production is interrupted.Thus negative effect be there is no to productivity ratio.
By special for checking the flow process started, all types of fault can be detected in principle.Compared with pure statistical analysis production process, in any case obviously extend the possibility of failure cause detection.
Described display unit can be the part of the common central control unit of station.All stations only need a display unit in this case.But also on each station, all can there is display unit.In this case, result is easier to be assigned to station.Result show various different feasible pattern, these feasible patterns can alternatively or mutually jointly be used.
Check result can comprise the instruction eliminating deviation.The operator that this result especially lacks to professional knowledge provides support.This instruction such as may reside in the request changing certain functional device.

Station 2 such as all has coiler device 24, and this coiler device 24 has bobbin cradle 18, bobbin drive unit 26 and Yarn lateral-movement device 28, and this bobbin cradle 18 can move around pivotal axis 19.Bobbin cradle 18 keeps cross winding bobbin 11 to be spooled and has sensor 44, and this sensor 44 detects the rotating speed of cross winding bobbin.
In an illustrated embodiment, cross winding bobbin 11 is close to head roll 26 with its surface in winding process, and is driven by rubbing by head roll 26.At this, head roll 26 is driven by adjustable rotating speed, reversible drive unit (not shown).Head roll 26 is effectively connected with sensor 45, and sensor 45 detects the rotating speed of head roll.Realize traversing when yarn 30 is wound up on intersected coiled bobbin 11 by means of Yarn lateral-movement device 28, Yarn lateral-movement device 28 in the present embodiment has Finger yarn guide 29.
In addition, winder station 2 also has Yarn Connecting apparatus (preferably with the piecing devices 13 of the operating pneumatic of cutter sweep 43), yarn under working sensor 22, surplus yarn cutting knife 49, yarn tensioner 14 (it is effectively connected with yarn pulling force sensor 46), yarn clearer 15 (it has yarn cutting device 17), upper Yarn senser 20 and waxing attachment 16.
In addition, winder station 2 is also provided with suction nozzle 12 and clamp yarn cop 25, and suction nozzle 12 and clamp yarn cop 25 all can be subjected to negative pressure by limiting mode.Here, suction nozzle 12 and clamp yarn cop 25 are connected to along on the longitudinal negative pressure channel 32 arranged of machine, and this negative pressure channel 32 himself keeps being connected with negative pressure source 33.
In addition, in the embodiment shown, in the region of waxing attachment 16, about yarn operating path stagger approximately backward arrange yarn mouth 23 of catching so locate, that is, yarn 30 in winding process catching yarn mouth 23 opening 42 front run.Catch yarn mouth 23 to be connected to equally on negative pressure channel 32 by air distributor 27.At this, air distributor 27 has catches the pipe joint 35 of yarn mouth 23 and relatively larger relief pipe joint 36 for first, and the suction nozzle 12 that the opening of relief pipe joint 36 is positioned in holding fix P at normal winding duration of work is hermetic closed.Relief pipe joint 36 is opened wide by the upwards pivotable of suction nozzle 12, and responsible releasing of opening wide of relief pipe joint 36 is present in the negative pressure of catching on yarn mouth 23.
In the present embodiment, have " off-line inspection " menu item in the actions menu of central control unit 50, when breaking aborning, this actions menu shows all winder stations or winds portions station in display unit 51.Submenu is there is when selecting off-line to check.Such operator can select the winder station that will check.Next can also select, should perform and allly check relevant check process with off-line, a functional device can be selected or multiple functional device can be selected, or the function group that will check its functional device can be specified.After completing selection, just can start to check.So, check multiple selected winder station 2 is parallel.
Only some possible check process of exemplary illustration below, utilize these check process can check each functional device.
In order to check the function of catching yarn mouth 23, upper yarn being placed on and catching yarn mouth 23 front.For this reason, suction nozzle 12 is from its holding fix P towards the direction pivotable of cross winding bobbin 11 and catch winding the yarn of having no progeny and being wound up on cross winding bobbin 11, and pivotable is back to holding fix P again afterwards.At this, yarn is put into yarn clearer 15 and Yarn Connecting apparatus 13 by suction nozzle 12.Correct the feeding that first yarn clearer 15 detects yarn is given.Once suction nozzle 12 arrives again its holding fix P, the relief pipe joint 36 of this front opening is closed again, and catches yarn mouth 23 and be subjected to negative pressure.Now, the yarn cutting device 17 of yarn clearer 15 or cutter sweep 43 chopped strands of Yarn Connecting apparatus 13.Suction nozzle 12 sucks cut-off yarn." what the free yarn ends being wound up into the yarn on cross winding bobbin there occurs " is and catches the functional relevant of yarn mouth 23.When catching yarn mouth and being working properly, then free loose thread can be held.So yarn is no longer arranged in yarn clearer 15.Yarn clearer 15 detects and finds " not having yarn ".In control device 40, signal is analyzed, this control device 40 also once controlled yarn feed to.When catching yarn mouth 23 and working abnormal, then do not suck yarn, this yarn is retained in yarn clearer 15.Yarn clearer 15 detects the existence of yarn.The control device 40 analyzing yarn clearer 15 signal detects fault.This, for checking that the flow process of catching yarn mouth has been documented in not in front disclosed DE 10 2,009 058 827 A1, wherein elaborates this.But in quoted this application file, circulation performs this flow process, but not the station inspection of manual triggers on central control unit 50.According to the present invention, by bus system 60, yarn mouth 23 check result of catching of selected winder station is sent to central control unit 50 to show.
Coiler device 24 has and is unshownedly lifted away from cylinder, and this is lifted away from cylinder and is lifted away from from head roll 26 together with cross winding bobbin 11 by bobbin cradle 18 when needed.Automatically the process of being lifted away from is started and by the rotating speed of driven head roll 26 compared with the rotating speed of cross winding bobbin 11 in order to check.
In addition, coiler device 24 also has mechanical brake, and after being lifted away from, cross winding bobbin 11 is braked static by this mechanical brake.By measuring braking time, control unit 40,50 can infer the wearing and tearing of brake.
Head roll 26 is driven by unshowned rotary drum electrical motor.In order to check that rotary drum electrical motor lubrication can impose constant current when cross winding bobbin 11 lifts to motor, it corresponds to constant driving moment.Then, the acceleration of motor and head roll 26 is measured.That is, the time reaching desired speed is measured.When acceleration is too low, then must lubricate rotary drum electrical motor.Alternatively, also can detect head roll is remained on the necessary moment of desired speed.At this, moment and motor current are proportional.This measuring principle corresponds to the reel for yarn that detects in DE 102,007 062 631 A1 on head roll around method used.
When upper Yarn senser 20 and yarn under working sensor 22 can break aborning (that is, without yarn) checked by reference measurement.When measured value and a reference value have deviation, the pollution of sensor can be inferred.
The result of all check process can be sent to central control unit 50.At this, each inspection can be shown together with correlation behavior in principle.That is, the inspection not obtaining mistake also can be shown.But meaningfully, especially when the personnel more shallow by qualification operate, only directly show error message, this is because can produce based on a large amount of station the super large data flow that this operator can not bear completely.Also text message can be shown in the display unit 51 of central control unit 50, such as " winder station 17: catch the blocking of yarn mouth " or " winder station 46: upper Yarn senser pollutes ".But also all status informations can be stored in a daily record document, expert operator also can be presented at this daily record document in the display unit 51 of central control unit 50 at certain time point after this.
The function of weaving loom of the present invention is described below with reference to two examples.Fig. 3 and Fig. 4 schematically shows compared with prior art additional, required control analysis device, and wherein, Fig. 3 relates to central control unit 50, and Fig. 4 relates to the control device 40 of winder station 2.
Cross winding bobbin 11 such as can reel according to length.That is, once the yarn be wound up on cross winding bobbin reaches predetermined length, just start to replace cross winding bobbin.In the embodiment shown, length of yarn utilizes the rotating speed of head roll 26 to determine, this rotating speed is measured by sensor 45.Except length of yarn, the diameter of cross winding bobbin 11 can also be monitored.Not only measure the rotating speed of head roll 26 for this reason, and utilize sensor 44 to monitor the rotating speed of cross winding bobbin 11.Can at the diameter of production period determination cross winding bobbin according to the ratio between the known diameter of head roll 26 and two rotating speeds.
Central control unit 50 also has processor 53 except having keyboard 52 and display unit 51, and this processor 53 performs the control task of central control unit and coordinates the exchanges data with bus system 60.Processor 53 has the device 59 of the production process (Produktionsverlauf) for more multiple station.That is, can the manufacturing parameter of more each station or qualitative data.In the present embodiment, cross winding bobbin diameter is compared.That is, calculate the diameter mean value of all winder stations of batch, and compared with each diameter of cross winding bobbin.The production process that mean value definition is expected.When cross winding bobbin diameter and mean value have deviation, the fault of the functional device of relative stations just can be inferred.According to this embodiment of the invention, central control unit has device 54 for determining the deviation between desired production process, that is, for determining the deviation of cross winding bobbin diameter and mean value.
The described deviation of cross winding bobbin diameter can have various different reason.May be the density variation of defective cross winding bobbin on the one hand.Bobbin density is determined approximately through yarn tension during reeling.In bobbin winder shown in Fig. 1, correct yarn tension combines guarantee by yarn tensioner 14 and yarn pulling force sensor 46.Also may be length determine mistake.Its reason may be sensor 45 fault measuring head roll 26 rotating speed.The fault of sensor 44 may cause makeing mistakes when determining diameter.
In order to trigger and monitor the check process of the following stated, the control device 40 of winder station 2 has processor 41.
When determining that deviation appears in completed cross winding bobbin 11 diameter, originally also want breaks in production, completed cross winding bobbin 11 is replaced by empty set cylinder.Utilize the automatic flow of processor 41 start-up check above-mentioned functions device.First by the operating means of winder station, yarn is so arranged in yarn and advances in road, that is, utilize yarn tensioner 14 can apply yarn tension yarn pulling force in other words to yarn, and can yarn tension be detected by yarn pulling force sensor 46.Now, when yarn stops advancing, utilize yarn tensioner 14 to produce the yarn tension of regulation, and utilize yarn pulling force sensor 46 to measure the yarn tension of this regulation.Because avoid other influences in described flow process as far as possible, so deviation can infer the fault of the system be made up of yarn chest expander 46 and yarn tensioner 14.Shown result is such as: " check yarn pulling force sensor and yarn tensioner! ".The possibility of result is also as follows: " with predetermined weight by yarn arrangement before yarn pulling force sensor ".If operator perform after an instruction, just can limit the scope of this fault further, this is because, so just can with yarn tensioner independently test yarn pulling force sensor 46.
In order to check sensor 45, cross winding bobbin can be lifted from head roll 26, and drive the motor of head roll 26 at the operating point place of regulation.When measured rotating speed has deviation with expectation rotating speed, fault can be inferred.Such as can show below: " check the revolution detector of head roll." or: " change the speed probe of head roll.”
Sensor 44 can be checked in a similar way, specifically, drive empty set cylinder by head roll 26.
In second example, use analytical equipment 47 and the yarn clearer 15 of the control device 40 of winder station 2, to determine the deviation between desired production process.Usually in bobbin winder, utilize yarn clearer 15 to determine the flaw occurred in the spinning process carried out above, during winding process, remove flaw by yarn clearer cutting.These flaws can be such as slubbing, details or hetero fibre.By the analytical equipment 47 of control device 40 analyze yarn clearer 15 measuring-signal and compared with the suitable threshold value previously determined.
But, in winding process, also there will be some problems, utilize yarn clearer 15 and analytical equipment 47 can detect these problems.Can utilize like this analytical equipment 47 of analyzing yarn clearer 15 signal to detect dilatory yarn (
) and yarn circle.But it is difficult for will distinguishing the result obtained by these two signals of yarn clearer 15.In these two results, measure in opening (Messschlitz) at yarn clearer and all threads detected.
Yarn circle especially may be occur due to the fault of yarn circle brake 48.Yarn circle brake 48 be arranged in road advanced by yarn be positioned at unwinding position 10 place weaving cop 9 near, yarn circle brake 48 can stop when reeling from weaving cop 9 unwinding yarn circle.
Dilatory yarn comes from the fault of surplus yarn cutting knife 49.Surplus yarn cutting knife 49 is operated when each bobbin change starts in principle, and it can stop the dilatory yarn of formation in the splicing of failure.
Use the present invention herein.When analytical equipment 47 has determined there is above-mentioned deviation with the production process expected, then trigger the inspection to surplus yarn cutting knife 49 and yarn circle brake 48 by the processor 41 of control device 40.
In order to check yarn circle brake 48, when breaking aborning, yarn under working (namely from the yarn of bobbin) is picked up by clamp yarn cop 25 and keeps.Yarn under working is put into yarn under working sensor 22 by clamp yarn cop 25.During this process, forbidding yarn circle brake 48.Then activate kink brake 48, that is, make the bar portion of yarn circle brake 48 be close to bobbin.Tighten static yarn thus.The short range motion tightening period can be detected by yarn under working sensor 22.If activation kink brake 48 at present Yarn senser 22 change do not detected, then can infer yarn circle brake 48 fault.Activate surplus yarn cutting knife 49 subsequently, it is set directly at below yarn under working sensor 22.When surplus yarn cutting knife 49 function is normal, yarn is cut off and the yarn remained above yarn cutting knife 49 is siphoned away by clamp yarn cop.Thus in yarn under working sensor, there is not yarn.This change can detect by yarn under working sensor 49 is corresponding.If the signal of yarn under working sensor does not change, then there is fault in surplus yarn cutting knife 49.
