The invention still further relates to the waxing attachment with sensing device, this waxing attachment is used for monitoring in the process of waxing at the yarn of advancing to the yarn course of station along the weaving loom producing cross winding bobbin the paraffin body consumption of the paraffin body installed in the mode that can rotate around rotation axis, wherein, sensing device comprises at least two detecting elements, wherein the first detecting element is arranged regularly relative to rotation axis measurement, second detecting element is then arranged on paraffin body or support, this second detecting element can be rotated around rotation axis on the one hand, can move linearly along rotation axis on the other hand, and the first detecting element and the second detecting element can be overlapped along rotation axis gradually by the straight-line motion of paraffin body.
The invention still further relates to the station of the weaving loom producing cross winding bobbin, this station has the waxing attachment that the yarn for advancing to the yarn course of station along the weaving loom producing cross winding bobbin is waxed, and described waxing attachment comprises can with the paraffin body of yarn contacts, for keeping the holding device of the rotary actuation of paraffin body, the feed arrangement for feeding paraffin body and the sensing device for the consumption state that detects the paraffin body reduced gradually because contacting yarn.
Background technology
Such as German Prospectus DE 42 26 265 A1 discloses this method and apparatus, wherein, the paraffin body that instruction like this constantly diminishes because of contact yarn reaches minimum, and method determines that paraffin body reaches the expection time of run of minimum by paraffin body weight, paraffin abrasion loss, Yarn count, these parameters of winding speed with account form.In this case, paraffin body is maintained in the device of respective design in the mode that can be rotated along the feeding axis perpendicular to yarn course.
But the shortcoming of this solution is, this account form can cause the mis-information about current in esse paraffin body size usually, therefore exists and uses up because paraffin body closes on and make the danger that the paraffin of yarn is under-supply.But on the other hand, even often also enough large paraffin body can be changed in advance, still spendable paraffin body waste product therefore can be produced, both unnecessarily, also very expensive.
In order to overcome these shortcomings, existing a lot of suggestion, such as, utilize proximity transducer to monitor the threshold value of critical paraffin body feeding.
Such as in DE 40 10 469 A1, just describe a kind of waxing attachment, the lever-like force-input device being wherein equipped with the radiated element of permanent magnet form abuts on the paraffin body of rotation from behind.In this this waxing attachment external, also sensitive member (such as Hall element) is positioned on fixing holding device.
When the radiated element of force-input device because paraffin body consumes all the time when fixing sensitive member, Hall element because of magnetic element near detecting its magnetic field.Then utilize electronic switching device directly or time delay produce the alerting signal requiring to change paraffin body.Shifter for the treatment of alerting signal can be set to, winding process directly be stopped or just stopping after the excess time of 10 minutes to 240 minutes, or just for operating personal provides optics to indicate.
But this shortcoming of excess time that indicates to be optically is, it is available that operating personal also must determine in fact each station also has how many excess times according to multiple parameter usually seriatim to manually.This operating mode bothers very much, and is easy to make mistakes.
Another shortcoming is, when on multiple station, instruction is about to change paraffin body, operating personal cannot reliably determine immediately before this station is forced to stop actually on which station in the urgent need to changing.
In addition, also exist operating personal often cannot to estimate from when produce the shortcoming of the alerting signal of excess time.
In addition, the above-mentioned waxing attachment carrying out work when using proximity transducer also has following shortcoming: due to structural restriction, sensitive member or corresponding radiated element can only arrange mutually in disadvantageous mode, thus make all the time can only with higher uncertain factor to estimate the excess time of paraffin body.
Summary of the invention
Task of the present invention is, overcomes the above-mentioned shortcoming of the method and apparatus for monitoring paraffin body consumption state at least partly.
The method of monitoring the paraffin body of waxing attachment in the process of being waxed by a kind of yarn of advancing in the yarn course of the station to the weaving loom along production cross winding bobbin solves task of the present invention, according to described method, sensitive member and can by the switchover element of this sensing element senses is guided in the mode overlapped each other according to the consumption state of paraffin body, and the consumption state of paraffin body is determined according to overlap ratio and the detection duration of detecting element that draws accordingly, wherein, detect duration to be drawn by the mutual relevant position of detecting element and geometrical property thereof.
That is, in order to determine the consumption state of paraffin body, not only simply can detect (wherein can assess the first detection signal up to now) between two detecting elements of the mutual correspondence of sensing device, and also can carry out qualitative evaluation to multiple detection signal according to the present invention, thus also can gather the detection duration relevant with the geometrical property of interactional transmitting or sensitive member between the detecting element of mutual process separated by a distance.Also can the gather detection period be assessed subsequently, thus very accurately can determine the excess time of corresponding paraffin body.
Radiated element and sensitive member process periodically mutually, can make monitoring more accurate.
" periodically " of the present invention refers to radiated element and sensitive member close to each other or process repeatedly regularly, such as, the motion of the continuous rotation of paraffin body moved with the straight-line feed of paraffin body and combine.

Detailed description of the invention
Figure 1 shows that the lateral plan of the station 2 of the weaving loom (being so-called automatic winder 1 in this situation) producing cross winding bobbin.
This type of automatic winder 1 has multiple similar station 2 be set up in parallel, on these stations, the cop 3 with less amount of thread produced by the upstream weaving loom (especially ring spinner) in production process is wound into high capacity of switch winding bobbin 5, these are known, are therefore not described in detail in this.
The station 2 of this type of automatic winder 1 with multiple different yarn monitoring processing equipment (as is known, is therefore not described in detail in this), in winding process, monitors and have from the yarn 16 of cop unwinding the yarn defect that need not remove.In addition, also in winding process, yarn 16 is waxed.In other words, guide yarn 16 through waxing attachment 19, this waxing attachment can reduce the friction coefficient of yarn 16, thus significantly improves motion and the sliding properties of yarn 16.
The waxing attachment 19 formed according to the present invention will be explained in detail after a while according to Fig. 2 and Fig. 3.
After completing cross winding bobbin 5, the service unit of (unshowned) automatic operation is utilized cross winding bobbin to be given the cross winding bobbin feedway 7 longitudinally arranged along machine, and to being arranged on yarn cylinder load station or the conveying of similar station of machine side.
As shown in fig. 1, this type of automatic winder 1 is also equipped with yarn cylinder and bobbin conveying system 6 usually, and cop 3 or bare bobbin are advanced on transfer dish 11.
Illustrate only in FIG the cop supply section 24 of this yarn cylinder and bobbin conveying system 6, can reverse drive memory paragraph 25, one of them leads to lateral transfer section 26 and the bobbin loopback section 27 of winder station 2.
Each station 2 also equally has the various devices ensureing that these stations normally run with described before.
Such device is known already, therefore only partly illustrates in FIG.
One of them this known devices is such as wind2 4, and this wind2 has the bobbin bank 8 installed in the mode can moved around pivotal axis 12.
Described in the present embodiment, cross winding bobbin 5 abuts on head roll 9 with its surface in winding process, and the head roll 9 of self-contained power effect drives yarn cylinder by frictional fit.
Reference numeral 33 represents the corresponding actuating device being connected to station computing machine 28 by control line 35.
Be provided with Yarn lateral-movement device 10, to make yarn 16 traversing in winding process.This known equally already and Yarn lateral-movement device 10 only schematically shown in FIG such as has the thread-carrier of the form of the yarn traverse bar 13 formed in finger-like.
The yarn traverse bar 13 worked by electromechanical actuating device 14 makes yarn 16 traversing between two end faces of cross winding bobbin 5 in winding process.
The actuating device 14 of thread-carrier 13 is connected with station computing machine 28 by control line 15 equally.
As previously mentioned, the station 2 of this type of automatic winder 1 also has waxing attachment 19 the immediately front of Yarn lateral-movement device 10 in yarn course region, and this waxing attachment can wax in winding process yarn 16.
Fig. 2 shows and to form according to the present invention and a kind of cutaway view of embodiment of waxing attachment 19 of work, this waxing attachment has new paraffin body 18, Fig. 3 shows the waxing attachment 19 at later time point, that is, at this time point, paraffin body 18 is wearing and tearing and before therefore this time point is in replacing construction point in a large number.
Waxing attachment 19 has fixing shell 23, and this shell is fixed on station shell 60 by (unshowned) support.The stepping motor 34 be connected with station computing machine 28 by control line 57 is fixed on this fixing shell 23.
By supporting member 36, wax cup 41 is bearing on the motor shaft 58 of stepping motor 34 in the mode of anti-rotating, in this wax cup, paraffin body 18 with anti-rotating but the mode that can move axially be bearing on supporting member 36.
Such as pivot plate 21 is hinged on fixing shell 23 above, this pivot plate can between control position and " loaded " position pivotable, and be locked in control position by such as permanent magnet assembly 22, described permanent magnet assembly is such as made up of the permanent magnet elements 29 be embedded in shell 23 and the pivot plate 21 be made up of ferromagnetic material.
Pivot plate 21 has stroke limitation component 17, can be regulated the different operating position of paraffin body 18 by the Angle Position of the trip limiting member, paraffin body in wax cup 41 can to move axially but the mode of anti-rotating is installed.
Also can find out from Fig. 2 and Fig. 3, paraffin body 18 is connected with the supporting member 36 of wax cup 41 in the mode of anti-rotating by the drive plate 37 with pin 38 or like, is therefore also connected with wax cup 41 in the mode of anti-rotating.
By spring installation 39, paraffin body 18 is moved axially on supporting member 36.This spring installation 39 is supported on pressing plate 40, and exerts a force along direction R to drive plate 37.In other words, paraffin body 18 moves along direction R in wax cup 41, until 30 to abut on stroke limitation component 17 before this paraffin body, and abuts in thus on the yarn 16 of advancing.
In the present embodiment, fixing shell 23 also has blowing nozzle array 54 as is known in its bottom section 45, and this blowing nozzle array is by the electromagnetic valve of constrained control being connected to positive pressure source.
In other words, the multiple blowing nozzles arranged in the form of a ring point to the annular gap 53 between the inwall 51 and the excircle 50 of wax cup 41 of shell 23, thus can blow out rapidly presumable impurity in annular gap 53 region without any problems.
As can be seen from Fig. 2 and Fig. 3 especially, waxing attachment 19 also has sensing device 20, and this sensing device is made up of the first detecting element 42 and the second detecting element 43 in this case.
In this embodiment, the first detecting element 42 is sensitive members of hard-wired rectangular Hall chip form, and this sensitive member is connected to station computing machine 28 by signal wire (SW) 44.
Second detecting element 43 such as exists with the form of circular permanent magnet, and its magnetic field is detected by Hall chip.Second detecting element 43 is fixed in the region, side of paraffin body 18.Detecting element 43 1 aspect is turned round together with paraffin body 18, on the other hand then along with the wearing and tearing change of paraffin body 18 translation near the first detecting element 42.
In other words, by the translation feed motion of pivotal paraffin body 18, two detecting elements 42 and 43 are overlapped gradually, thus make Hall chip finally permanent magnet be detected.In other words, each when permanent magnet along rotate or gyratory directions periodicity through Hall chip time, Hall chip all can detect permanent magnet.
Because permanent magnet is preferably rounded, therefore the front summit of this permanent magnet is first near Hall chip, thus first occurs overlapping in apex region, originally only has very little coincidence.
In winding process, due to paraffin body 18 spillage of material caused by the feed motion of paraffin body 18, therefore paraffin body 18 often revolves and turns around, and this coincidence degree will increase, until reach the greatest coincide degree of detecting element 42 and 43.
When permanent magnet with its whole width through Hall chip time, then the maximal degree of coincidence of detecting element 42 and 43.
Described action principle can cause again the detection duration between permanent magnet and Hall chip constantly to increase in winding process, and this situation carries out determining and analyzing preferably by station computing machine 28.
Obviously, when the direction of feed of this detecting element and paraffin body 18 and/or rotation or gyratory directions phase universal time coordinated, as an alternative or supplement, also can utilize the sensor geometry of detecting element 42 to determine and detect duration.
If detect duration when reaching the value that certain can set arbitrarily, the station computing machine 28 in relative stations 2 will trigger optical signalling 31, and this station 2 of operating personal of instruction automatic winder 1 is about to need to change paraffin body.
Such as can arrange until trigger optics alerting signal 31 time period used according to the determined value detecting duration.
In the present embodiment can according to formula X
report to the police[%]=(t
current-t
for the first time)/t
for the first timecalculate and determine the threshold X of energizing signal
report to the police, so just especially reliably can monitor the consumption of paraffin body.
Such as can select separately the time point of trigger alarm signals, such as can trigger alarm signals in a case where:
X
report to the police=20% or 50% or 90%.
Curve Figure 49 shown in curve Figure 48 and Fig. 5 according to Fig. 4 further illustrates other available method.
According to the method shown in Fig. 4, determine step number performed in the process that the stepping motor 34 of waxing attachment 19 overlaps at corresponding detecting element 42 and 43.
The axis of ordinate 32 of the Figure 48 of curve shown in Fig. 4 is detect overlap ratio first time until reach the step number of stepping motor 34 in the process of the greatest coincide degree being substantially equivalent to paraffin body 18 final position.
Axis of abscissa 46 for first time detect after until still spendable excess time before reaching paraffin body 18 final position.
Because paraffin body 18 not rotates along a hand of rotation consistently, but in fact after each winding interrupts, change its hand of rotation, and two hand of rotation have slightly different overlap ratios and detect duration, therefore curve Figure 48 illustrates two curves.
Top curve 64 represents the step number that stepping motor 34 performs when overlapping when paraffin body 18 left-hand revolution.
Lower curve 65 represents the step number that stepping motor 34 performs when overlapping when paraffin body 18 clickwise.
Can know according to curve Figure 48 and find out, the counting step number of actuating device 34 constantly increases, this is because the detection duration measured between two detecting elements 42 and 43 constantly increases along with the feeding of paraffin body 18 and associated consumption.Can know and find out that the excess time arrived before paraffin body 18 final position increases and corresponding reduction with step number.
When such as triggering when the stepper motor steps of determined detection duration inside counting is the alerting signal of 80 steps after time point x1=1300s (top curve 64) and x2=1750s (lower curve 65), before relative stations 2 stops due to critical paraffin body state, the also remaining 3700s (x1=1300s) or 3250s (x2=1750s) excess time of paraffin body 18.
The different curvilinear motions of top curve 64 and lower curve 65 can have different reasons, such as, may produce these difference due to the error of detecting element 42 and 43, not be further expalined for this here.
Consider that the relative value of excess time replaces the absolute value the same with curve Figure 48 if adopted, the error that may exist can be made up well, then advantageously curve Figure 49 as shown in Figure 5 equally can set percentage threshold.
Formula needed for calculating is:
X
warning _ step number[%]=(step number-the first step number of current mensuration)/the first step number
The axis of ordinate 52 of curve Figure 49 represents the step number of stepping motor 34 with percentum, the step number that namely stepping motor 34 is performed when detecting element 42,43 reaches certain overlap ratio.
Axis of abscissa 55 be detect first time after reaching the final condition of paraffin body 18 and excess time of still spendable paraffin body 18 before closing relative stations 2.
Two curves 56 and 59 be close to reflect the different rotary direction that paraffin body 18 may occur.
If such as calculate relative threshold X when the about 3000s of time point x3=
warning _ step numbertrigger alarm signals when=100%, then relative stations 2 was only left about 2000s before forcing owing to reaching critical paraffin body state to stop.
What illustrate at this especially has the following advantages compared with common method flow for the method flow of monitoring paraffin body state.
First, greatly can shorten excess time, the risk changing still spendable paraffin body 18 too early can be reduced thus.
Secondly, can at each station 2 place than ever more accurately and trigger the signal being about to change paraffin body later.Thus, operating personal can be instructed better when really to need to change paraffin body 18.
Moreover, according to the parameter of paraffin body 18 used and/or yarn used 16, can more specifically regulate the activation time point of alerting signal of the present invention.
All these all significantly can reduce the risk that each station 2 is forced to stop.
Obviously, above-described embodiment only relates to the first embodiment of the method for the invention and relevant waxing attachment.But embodiments of the present invention are not limited to this embodiment.
