Description
The present invention relates to a kind of weaving loom, bobbin winder especially, it has a large amount of stations, and these stations have the functional device for the executable operations function; Be used for the device at production period monitoring production process; And device, they are used for the deviation between the definite and desired production process.
EP 0 685 580 B1 disclose this weaving loom, and it is for the flaw of yarn, rove and the webbing determining to be caused by the production reason.In first step, the fault of use-case during the sensor of the part of clearing equipment detect to be produced in this way.Measured value and one or more threshold ratio and are sorted out in classification district.The district obtains fault sample by classification, it can be compared with modeled predetermined reference sample, and these reference samples can be inferred the reason that causes detected fault.The measured value that disclosed solution relates to the production period detection among EP 0 685 580 B1 carries out statistical analysis.Yet can not determine for a long time by this way all failure causes.Must in certain hour, produce in the defectiveness mode in addition, in order to determine failure cause.
DE 39 17 055 A1 disclose a kind of device, and it is used for monitoring and makes the reel for yarn of coiler device of weaving loom of cross winding bobbin around production process.At this, not that monitoring product is determined failure cause, but analyze manufacturing parameter, monitor in this case traverse amplitude and/or frequency of transverse moving.Yet can only detect some failure cause at this, for example yarn tensioner or cylinder fault.
DE 40 31 419 A1 disclose a kind of weaving loom, bobbin winder especially, and it has a large amount of stations, these stations have the functional device of executable operations function, wherein, give the common central control unit of these work position distributions, this central control unit has operating means and display unit.DE 40 31 419 A1 disclose a kind of automatic winder, and it has a plurality of winder stations that are arranged side by side.When weaving loom or its control module detect abnormal condition, just show this abnormal condition to the operator.For analysis of failure, the operator can manually activate slow testing process and the range estimation monitoring flow process of station.By this way, the operator can determine possible failure cause based on its professional knowledge, checks in maintenance span perhaps whether weaving loom is working properly.On the control device of weaving loom, can input required maintenance work and corresponding service intervals.In addition can be in the executed work of control device input.Can simply check some work of whether and when carrying out by this way.In these maintenance works, for example carry out functional check by visual inspection, cleaning function element, lubricated movable part or preventative replacing function element.
DE 602 19 260 T2 disclose a kind of bobbin winder, and wherein each winder station can be individually especially checks by estimating.For this reason, the operator must activate checking mode and specify the station that will check at equipment control device.Afterwards, the operator goes to corresponding station and activates the invalidating switch.The operator can directly carry out at station and check like this.
With regard to regard to DE 40 31 419 A1 or the described work of DE 602 19 260 T2, always need corresponding weaving loom is had the higher personnel of technical ability of accurate understanding.In addition, when station quantity is more, visual inspection individual inspiration very complex and consuming time in other words on each station.
Undocumented DE 10 2,010 034 971 A1 are based on the weaving loom according to DE 40 31 419 A1, especially bobbin winder, it has a large amount of stations, these stations have the functional device of executable operations function, wherein, be furnished with common central control unit for 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 the weaving loom, on a station, can carry out the flow process of automatic inspection functional device, when breaking aborning, utilize the operating means of central control unit can trigger the before flow process of at least one functional device that determine, the automatic inspection station.Be provided with for the device that the result is transferred to central control unit, and can read check result in the central control unit display unit.
By this solution, carry out inspection by pressing button to a certain extent.In the weaving loom central control unit, realized " intelligence " that inspection is judged.The operator is reading result directly, and then obtains processing prompting.For example can show, some functional device pollutes and should clean, and perhaps the not correct work of functional device should be changed.Because in machine, realized intelligence, so can be like a cork by carrying out these work through the start-up.Yet also giving, the present invention have the qualification personnel that the possibility of fast and effeciently carrying out maintenance and trouble shoot is provided.Inspection can be carried out by central control unit fully.Need not to go to the station place.
Can utilize the predetermined station that will check of operating means according to an embodiment.Can be scheduled to check all stations of weaving loom.Yet also can only check a part of station.For example shut down and other part stations when continuing to produce when this part station, this is significant.Also can check targetedly at production period and show unusual station.
Simultaneously can utilize operating means to trigger the inspection of these predetermined stations.That is to say, executed in parallel is to the automatic inspection of these predetermined stations.Can guarantee by this way fast and effeciently to safeguard.
According to disclosed other embodiments among DE 10 2,010 034 971 A1, can utilize operating means to trigger the flow process of previous a plurality of equipments that determine, the automatic inspection station.Thus, especially simplified inspection for the more shallow personnel of qualification, this is because can utilize button to check a plurality of functional devices to a certain extent.The operator not necessarily leaves no choice but the functional device that oneself selects to belong to this flow process.At this, the flow process that triggers can trigger whole the inspection, perhaps the part of audit function device only.At least one functional device that will check can utilize operating means predetermined.Thereby can realize individual inspiration.
According to advantageous manner, the function group of giving these functional device distribution function groups of station and can select to check.Especially be during about this function group unusually when producing, the operator can use this option.Central control unit can show that these are unusual based on the automatic analysis creation data, observes to identify perhaps that these are unusual by operator's specialty.

Utilize the solution of DE 10 2,010 034 971 A1 can obtain the gratifying result of maintenance.Yet when unusual and fault occurring during the technological process of production, this solution only provides very limited help to amateur operator.Although show the deviation that production period occurs, yet the operator can only determine alone about the deviation of each functional device and targetedly it be tested.The professional knowledge that relates to operating personnel is analyzed in execution error.Only kept outside conventional maintenance for amateur operator, carried out the possibility of all functions device to test flow process.This means needs the plenty of time.Can not produce during this period, thereby reduce productivity.
Based on disclosed weaving loom among EP 0 685 580 B1, wherein, the device of the deviation between the device of the production process of existence monitoring production period and the definite and desired production process, task of the present invention is, improvement is to the detection of the fault that formed by the deviation in the production process, the reason that realizes fast and determine exactly to cause the deviation between production process and the desired production process as far as possible.
According to the present invention, this task solves feature according to claim 1.Favourable improved procedure of the present invention is the theme of dependent claims.
In order to solve this task, on station, can carry out the flow process of automatic inspection functional device, and when setting device is used for breaking aborning, the flow process of before having determined according to determined deviation trigger, be used at least one functional device of automatic inspection station, wherein, be provided with display unit and be used for check result is transferred to the device of described display unit, in order in described display unit check result is shown.
In weaving loom of the present invention, when deviation occurring between production process and the desirable production process, automatic start-up check.The flow process of carrying out in order to check is relevant with Deviation Type.That is to say some functional device that inspection may be relevant with deviation targetedly.The result can show to the operator, and with its fast and without loss in productivity offer the operator.
Produce intercourse and carry out inspection.Produce and interrupt and to carry out targetedly, can wait until that perhaps normal production interrupted next time.Specific practice can be decided on Deviation Type.In the larger situation of deviation, (for example produce product substandard products are arranged), originally also can breaks in production.In case of necessity, can trigger at once inspection and directly the result be offered the operator by machine.Like this can fast detecting failure.When deviation is not serious, when producing interruption, trigger checking next time.In bobbin winder, for example at broken yarn or more occur this production during change of bobbins and interrupt.Thereby productivity ratio there is not negative effect.
For checking the flow process that starts, can detect all types of faults by specially in principle.Compare with pure statistical analysis production process, in any case obviously expanded the possibility that failure cause detects.
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.Yet also can on each station, all there be display unit.In this case, the result is easier to be assigned to station.The result shows various different feasible patterns, and these feasible patterns can alternatively or mutually jointly be used.
Check result can comprise the indication of eliminating deviation.This result especially provides support to the operator that professional knowledge lacks.This indication for example may reside in the request of changing certain functional device.
Check result can also comprise the explanation of relevant deviating cause.By this way, the technical staff is accurately illustrated, need not oneself operation.Decide adequate measure in its sole discretion by it.
Check result can be used as text and illustrates in display unit.That is to say the correlated phenomena that is defined with written mode explanation.This demonstration provides understandable information.Need in handbook, not search the implication of signal or code.
If failure cause is not attributable to definite functional device and utilize automatic flow can only determine that one group of functional device is as reason, if perhaps more accurately accident analysis is complicated according to the automation mode, check result can comprise the indication that is intended to more accurately determine deviating cause so.
Device for the monitoring production process according to the present invention can comprise the device for monitoring converted products quality.This device is known in the prior art on the principle and for example is being disclosed in typical EP 0 685 580 B1.

Function below with reference to two example explanation weaving looms of the present invention.Fig. 3 and Fig. 4 schematically show compared with prior art additional, essential 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 for example can be reeled according to length.That is to say, in case the yarn that is wound up on the cross winding bobbin reaches predetermined length, just begin 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, can also monitor the diameter of cross winding bobbin 11.Not only measure the rotating speed of head roll 26 for this reason, and utilize the rotating speed of sensor 44 monitoring cross winding bobbins 11.Can determine at production period the diameter of cross winding bobbin according to the ratio between the known diameter of head roll 26 and two rotating speeds.
The described deviation of cross winding bobbin diameter can have various different reasons.May be the density variation of defective cross winding bobbin on the one hand.Bobbin density is roughly determined by yarn tension during reeling.In bobbin winder shown in Figure 1, correct yarn tension is united assurance by yarn tensioner 14 and yarn pulling force sensor 46.It also may be the mistake of determining of length.Its reason may be to measure sensor 45 faults of head roll 26 rotating speeds.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 deviation appears in definite completed cross winding bobbin 11 diameters, originally also want breaks in production, in order to completed cross winding bobbin 11 is replaced by the empty set cylinder.Utilize the automatic flow of processor 41 start-up check above-mentioned functions devices.At first by the operating means of winder station, yarn so is arranged in yarn advances in the road, that is, utilize yarn tensioner 14 to apply in other words yarn pulling force of yarn tension to yarn, and can detect yarn tension by yarn pulling force sensor 46.Now, when yarn stops to advance, 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 in described flow process, avoided other influences as far as possible, so deviation can be inferred the fault of the system that is comprised of yarn chest expander 46 and yarn tensioner 14.Shown result for example is: " check yarn pulling force sensor and yarn tensioner! ".The possibility of result is also as follows: " with predetermined weight with yarn arrangement before the yarn pulling force sensor ".If the operator has carried out a rear instruction, just can further limit the scope of this fault, this be because, so just can with yarn tensioner test yarn pulling force sensor 46 irrespectively.
In order to check sensor 45, can lift cross winding bobbin from head roll 26, and drive the motor of head roll 26 at the place, operating point of regulation.When measured rotating speed has deviation with the expectation rotating speed, can infer fault.For example can show below: " check the revolution detector of head roll." or: " change the speed probe of head roll.”
Can check in a similar way sensor 44, particularly, drive the 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, with the deviation between the definite and desired production process.Usually the flaw that occurs in the spinning process that utilizes yarn clearer 15 to determine to carry out previously in bobbin winder is removed flaw by yarn clearer cutting during winding process.These flaws for example can be slubbing, details or hetero fibre.By the analytical equipment 47 of control device 40 analyze yarn clearers 15 measuring-signal and with the suitable previous threshold of determining.
Yet, in winding process also some problems can appear, and utilize yarn clearer 15 and analytical equipment 47 can survey these problems.Can utilize like this analytical equipment 47 of analyzing yarn clearer 15 signals to detect dilatory yarn
With the yarn circle.Yet it is difficult will distinguishing the result that these two signals by yarn clearer 15 obtain.In these two results, in yarn clearer measurement opening (Messschlitz), all detect threads.
The yarn circle especially may be that the fault owing to yarn circle brake 48 occurs.Yarn circle brake 48 is arranged in yarn is advanced road near the weaving cop 9 that is positioned at 10 places, unwinding position, and yarn circle brake 48 can stop when reeling from weaving cop 9 unwinding yarn circles.
Dilatory yarn comes from the fault of surplus yarn cutting knife 49.Surplus yarn cutting knife 49 is operated when each bobbin change begins in principle, and it can stop to form in the splicing of failure draws yarn.
Use herein the present invention.When the definite production process with expectation of analytical equipment 47 had above-mentioned deviation, then the processor 41 by control device 40 triggered remaining the inspection of yarn cutting knife 49 and yarn circle brake 48.
In order to check yarn circle brake 48, when disconnected aborning, the yarn under working yarn of bobbin (namely from) is picked up by clamp yarn cop 25 and keeps.Clamp yarn cop 25 is put into yarn under working sensor 22 with yarn under working.During this process, forbidding yarn circle brake 48.Then activate kink brake 48, that is, so that bobbin is close to by the bar section of yarn circle brake 48.Tighten thus static yarn.Short distance athletic meeting during tightening is detected by yarn under working sensor 22.If activate kink brake 48 at present Yarn senser 22 do not detect variation, then can infer yarn circle brake 48 faults.Activate subsequently surplus yarn cutting knife 49, it is set directly at yarn under working sensor 22 belows.When surplus yarn cutting knife 49 functions were normal, the yarn that yarn was cut off and remained yarn cutting knife 49 tops was siphoned away by clamp yarn cop.Thereby in the yarn under working sensor, there is not a yarn.This variation can be by yarn under working sensor 49 corresponding detecting.If the signal of yarn under working sensor does not change, then there is fault in surplus yarn cutting knife 49.
