Description

The device of yarn flaws is removed from yarn
Technical field
The present invention relates to device, the tools for removing the yarn flaws by different yarn flaws classification of type from yarn There is the weaving loom of the manufacture winding bobbin of such device, store at least one corresponding to yarn flaws type for that can call Seek the storage unit of yarn program and for obtaining the method for falling on the loose thread on winding bobbin.
Background technique
In textile industry, the weaving loom of various types of manufacture winding bobbins is popular very early.In addition to open-end spinning frame Outside, such as largely bobbin-winding machine has been used.
On bobbin-winding machine station, spinning bobbin that is being manufactured on ring spinner and only including relatively little of thread material By rewinding at large package winding bobbin.Yarn is monitored whether have yarn flaws during rewinding, wherein the yarn flaws quilt It cuts away and is substituted by the engagement yarn almost as yarn.
For this purpose, the upper yarn for always not only needing to fetch from winding bobbin on the winder unit of bobbin-winding machine, it is also desirable to come from The lower yarn of unwinding cheese.
In general, certainly by the winder unit computer starting station of related winder unit in controllable clearing cutting The yarn of body engages automatic device.
That is firstly, suction nozzle bears suction sky on the surface of the winding bobbin slowly rotated on the contrary with coiling direction Gas.After capturing upper loose thread, suction nozzle is pivoted to yarn insertion position, and on the position, suction nozzle mouth is seated under yarn splicing device Side.Then, the clamp yarn cop for being located below initial position is pivoted to top operating position and extracts out and at the same time taking away from unwinding cheese Lower yarn.
A large amount of station has station computer respectively, itself is connected with the central control unit of weaving loom.
Generally, on the central control unit of weaving loom adjustable yarn clearer response sensitivity, that is, Ke Yi Whether center setting inhomogeneities is classified to yarn flaws.Yarn flaws refer to common and rare yarn flaws, at this In, common yarn flaws are also referred to as yarn defect, also include cotton knot other than slubbing and details.If it find that inhomogeneities and general It is classified as yarn flaws, because having exceeded scheduled tolerance limits, then yarn clearer triggering clearing cutting.
It is for example disclosed in DE19640184A1, yarn is extracted and fills by winding from unwinding cheese such as spinning bobbin It sets and is wound into winding bobbin such as cross winding bobbin.Moving yarn is directed over the measuring head and cutting machine of yarn clearer Structure.Yarn clearer measurement represents the measured value of yarn qualities.When yarn clearer find flagrant flaw when, i.e., when measurand not When being same as predetermined value, so-called clearing is triggered by yarn clearer and is cut off, i.e., cutting mechanism is actuated to remove the fault part of yarn. After yarn cutting, the loose thread with fault part is fallen on winding bobbin.Loose thread is captured and is had by pivotable suction nozzle The yarn line segment of flaw is sucked away.Upper yarn from winding bobbin is placed into yarn splicing device and is cut with yarn line segment defective Fall.Correspondingly, the lower yarn from unwinding cheese is placed into yarn splicing device by pivotable clamp yarn cop and forms yarn and connects Head.
Method and apparatus for classifying and removing yarn are disclosed by EP0531894A1, whereby foundation and yarn rugosity Yarn flaws are imaged in the deviation of theoretical value bidimensional on regulation length of yarn.The yarn flaws are by measuring device and diameter and its Length is relatively found, and is then done and is assessed and classify according to the classification area of flaw matrix.For this purpose, pressing quantity in classification area Know the frequency of occurrences that meets the yarn flaws of respective classification standard and is shown in the form of bidimensional.By showing on the screen Show, the appearance of flaw frequency can be discovered according to shown quantity in each classification area.
However, it is known that method and apparatus have in common that, although identifying and grasping different yarn flaws types, deposit And suction nozzle of the operation for capturing upper yarn seek yarn program, but with the capture of upper yarn relatively also disclose the capture of upper yarn not at To optimize suction nozzle when function continuously to adjust and improve to the distance of winding bobbin and in entirely winding stroke to capture upper yarn And existing negative pressure, but seek yarn program and seek unity of action for the yarn flaws being found.
Summary of the invention
Therefore the first aspect of the present invention is related to a kind of being divided for removing from yarn by different yarn flaws types The device of the yarn flaws of class, the device have for measure at least one can scheduled yarn parameter measuring head and be suitable for It signals to show that there are yarn flaws and yarn flaws type in the case where being different from numberical range relevant to yarn parameter And it based on the triggering clearing cutting of yarn flaws signal, is cut off by the clearing, yarn flaws fall on the spinning of manufacture winding bobbin On the winding bobbin of loom.
The characteristics of device proposed is that described device is associated with storage unit, is directed to different yarns in the memory unit Line flaw type is stored with seeking for the weaving loom suction nozzle for the loose thread search designed for upper yarn respectively in a manner of it can call Yarn program, and the device is suitable for seeking yarn program according to the yarn flaws type starting for signaling to show is corresponding to be caught with suction nozzle Obtain the loose thread for having fallen on the upper yarn on winding bobbin.
In this way, what can be adapted to individually for a kind of execution of yarn flaws type seeks yarn program.In trial It has been determined that the difference for different yarn flaws types seeks yarn parameter and improves upper yarn capture.Substantially, yarn flaws type quilt It is divided into slubbing, details and cotton knot, herein, can also be subdivided into some yarn flaws types further within the scope of the present invention Group.
Yarn parameter is sought for example including pressure-reduction level, suction nozzle to winding bobbin circumferential surface distance for capturing from winding bobbin Upper yarn loose thread and suction nozzle when capturing upper yarn whether and which kind of time interval movement of nodding is carried out with.Suction nozzle can also it is continuous or Bear negative pressure in pulsation ground.In principle, seeking yarn parameter includes all parameters relevant to the capture of upper yarn.
Such as it has become clear that, under details advantageously, under high negative the suction nozzle closer to Winding bobbin circumferential surface is in place.On the contrary, even in suction nozzle far apart compared with can reliably capture slubbing, cotton knot under lower negative pressure It is captured with the negative pressure further decreased, perhaps obtain the cephalomotor support of point of suction nozzle.
It seeks yarn program to be stored in storage unit and can get, therefore can be held according to the yarn flaws type found Row seeks yarn program corresponding to current yarn flaws type.That is, triggering so-called clearing if the device for example finds slubbing Cutting shows yarn flaws type to remove the yarn flaws subsequent signal from yarn.Because being associated with depositing for the device Be stored in storage unit also for slubbing yarn flaws type and individually seek yarn program, thus select and execute this seek yarn program with Just the upper yarn loose thread on winding bobbin is fallen on suction nozzle capture.For slubbing it is optimised described in seek yarn program at least one ginseng Number aspect seeks yarn program for other yarn flaws types different from what remaining was stored.
Since what is individually adjusted for different yarns flaw type seeks yarn program, the capture rate (rate) for seeking yarn is changed It is kind, it is possible thereby to which overall capture upper yarn more quickly.It is possible thereby to continue the winding process after clearing cutting more quickly, And engine efficiency of weaving is improved.(under the negative pressure condition, it is current that suction nozzle is only applied acquisition to the negative pressure most preferably set at this time Negative pressure needed for loose thread) finally also advantageously act on the energy consumption of weaving loom.
In a preferred embodiment of the present invention, it can determine and store the yarn for every kind of yarn flaws type The capture rate of line search, and yarn program can be sought with adjust automatically when capturing rate and being different from limiting value.
If being directed to every kind of yarn flaws type identification and storing yarn loose thread can not be how frequently caught by suction nozzle Obtain and if define in the memory unit limit permission unsuccessful yarn obtain number of attempt limiting value, Change at least one when going beyond the limit of value and seeks yarn parameter.Such as suction nozzle can be positioned or be deposited closer to or further from winding bobbin It is that the negative pressure in suction nozzle is reduced or increases.Instead of the negative pressure being permanently present, suction nozzle can also bear negative pressure with pulsing, or Suction nozzle can execute movement of nodding.Range according to the present invention, individually seek yarn parameter can be changed or it is multiple seek yarn parameter can To be changed in combination with one another.
The adjust automatically of yarn program is sought advantageously individually for corresponding station, for product group or for entire weaving loom It carries out.
Can so select to seek yarn program adjust automatically (in adjustment at least one seek yarn parameter because be different from for Yarn captures the limiting value of rate and is changed), i.e., it is for example carried out for some station.This may be for example in its spinning machine The sample cylinder period of the day from 11 p.m. to 1 a.m is wound on one of them described station may be advantageous.It is also possible to advantageous is to be confined to adjust automatically One product group or a batch, if manufacturing multiple batches simultaneously on the textile machine or and if not all station is occupied. It is also contemplated that the adjust automatically for seeking yarn program is carried out for entire weaving loom.
The storage unit is preferably made of station control device, central control unit or external memory unit.
Range is it is possible that be wherein stored with and adjustable land used is stored with a variety of different yarn programs of seeking according to the present invention Storage unit is the station control device natively having or central control unit component part.This is favourable, because can Using the device and structure natively having, the new structural member complicated without addition.But the storage unit is also possible to external agency, Such as USB disk or electronic device, such as computer, tablet computer, smart phone, itself and the weaving loom or device can be made It is connected.This for example can be following medium, which can be docked to described device or weaving loom by suitable interface, Or it can wireless effectively connection therewith.

After cross winding bobbin is made, cross winding bobbin by automatic work service unit and preferably (not Showing) cross winding bobbin more changing device is transported to the cross winding bobbin conveying device 5 along machine length and is transported to Bobbin loading depot etc. set on machine end side.
Such bobbin-winding machine additionally has the logistics device in 6 form of bobbin and bobbin conveying system.In bobbin and cylinder In pipe transportation system 6, spinning bobbin 2 and bare bobbin recycle on transfer dish 7.
In addition, such automatic winder is generally configured with (not shown) central control unit, pass through machine bus and list The individual winder unit computer of a winder unit is connected, and is connected with the control device of service unit.Storage unit 8 exists It is made of in this embodiment winder unit computer.
Fig. 1 illustrate only above-mentioned bobbin conveying system 6 coil supply section 9, can be just anti-driven savings section 10, pass to volume Lateral transfer section 11 and bobbin around unit feed back section 12.
Provided spinning bobbin 2 is fallen in unwinding position 13 (being located in 11 region of lateral transfer section on winder unit) Cylinder is at large package cross winding bobbin.Some individual winder units at this time as is known and thus only indicate ground have it is various not Same device, they guarantee that the station is run by regulation.Described device is, for example, suction nozzle 14, clamp yarn cop 15 and yarn splicing device 16。
Yarn splicing device 16 is preferably designed to air-flow receiving cripper.Air-flow receiving cripper about normal yarn trend slightly withdraw and Have upper clamping cutting mechanism and lower clamping cutting mechanism.
The device of the invention that such winder unit is also equipped with yarn tensioner 17, is designed to yarn clearer in this example 18 pass with other devices not being shown specifically such as waxing attachment, yarn cutting mechanism, yarn tension sensor and lower yarn Sensor.
The overall winding device indicated with appended drawing reference 19 is made of bobbin cradle 20, can be around 21 activity installation of pivot axis And there is the mechanism for being used for rotatably keeping cross winding bobbin bobbin.
In winding process, cross winding bobbin is sticked on fluting roller 22 with its surface and is opened by being frictionally engaged Trough roller cylinder 22 drives.
As previously mentioned, each winder unit has a suction nozzle 14 and a clamp yarn cop 15, they pass through suction respectively Air pipe fitting is connected to the suction channel 23 along machine length.
Suction nozzle 14 can be pivotally mounted on around axis 24.The pivoting action of suction nozzle 14 is by being placed in winder unit shell 26 Pivot driver mechanism 25 executes.Pivot driver mechanism 25 is controlled by winder unit computer.Suction nozzle 14 is in 24 region of axis With the unshowned controllable means of communication with suction channel 23.Suction nozzle 14, which has, falls on or has fallen on friendship for being sucked or capturing Pitch the suction slot 27 of the loose thread on winding bobbin.Suction nozzle 14 can be seated in friendship by pivot driver mechanism 25 with its suction slot 27 It pitches in winding bobbin region.Here, suction slot 27 is roughly parallel to the extension of cross winding bobbin circumferential surface.Determine ground by bobbin shape Such as occur deviateing collimation under conical tube subcase.
Clamp yarn cop 15 can be pivotally mounted on around rotation axis 28 and additionally have clamp yarn cop lid 29 in its free end, Allow to close clamp yarn cop mouthpiece.
Fig. 1 shows winder unit state during normal winding.Suction nozzle 14 is seated in intersection with its suction slot 27 In winding bobbin region and the suction slot 27 is directed toward cross winding bobbin.In winding process, the diameter of cross winding bobbin It is incremented by.The distance of suction slot 27 to cross winding bobbin circumferential surface changes as a result,.In order to compensate for this change, suction nozzle 14 is according to friendship The diameter for pitching winding bobbin is moved around axis 24.In this way, the distance of suction slot 27 to cross winding bobbin circumferential surface can To be kept within the specified scope.
Clamp yarn cop 15 is positioned in low level during normal winding, that is, clamp yarn cop mouthpiece is located at 16 lower section of yarn splicing device And it is looked over before the trend of yarn 4 from operator's sight.
Process in clearing cutting is controlled by winder unit computer in the present embodiment.But it is also possible that the control System is completed such as central control unit by other control devices of weaving loom or is started by the connected control unit in outside.
Start clearing cutting after finding yarn flaws.Lower yarn 30 is typically maintained in yarn tensioner 17, and upper yarn It runs on the surface of cross winding bobbin.Yarn flaws type is that details is also transmitted and shows in this example.
Once finding broken yarn by winder unit, then suction air is applied to suction nozzle 14, yarn program rule are sought by selected at this time Pressure-reduction level is determined.Meanwhile the braking process of cross winding bobbin is activated, the cross winding bobbin and coiling direction being braked Slowly rotation on the contrary.According to yarn program is sought, the suction slot 27 of suction nozzle 14 is different far and nearly positioned at the circumferential surface of cross winding bobbin On.It seeks yarn program and alsies specify whether suction nozzle 14 continuously retains in the position during capturing loose thread or whether suction nozzle 14 for example exists Nod movement (nodding motion) is carried out during this.
If upper yarn cannot be captured by suction nozzle 14 or cannot correctly be captured by suction nozzle 14, upper yarn is directed to current yarn flaws class Type is individually predicted and is stored.Limiting value is defined in winder unit computer, defines 10 for details in this example Secondary trial capture is had no result.Once having no result it was found that 11 trials capture upper yarn, then adjust automatically is stored in winder unit computer Seek yarn program.That is, the distance of suction nozzle 14 to cross winding bobbin is reduced.Next time after finding details picks up yarn When, suction nozzle 14 is moved into the correct distance away from cross winding bobbin.
After upper yarn has been received in suction nozzle 14, suction nozzle 14 is pivoted from its initial position as shown in Figure 1 along dotted line 31 To final position.
When upper yarn is captured and is sent to yarn splicing device, is picked up by clamp yarn cop 15 and arrive lower yarn 30.Clamp yarn cop 15 The region for being close in 17 lower section of yarn tensioner is switched to its clamp yarn cop mouthpiece thus and clamp yarn cop 15 uses air-flow there Capture lower yarn 30.Meanwhile the control cam slide being placed on clamp yarn cop lid 29 is by controlling guiding piece under (not shown), thus Clamp yarn cop lid 29 is opened.Once clamp yarn cop 15 has captured lower yarn 30, then clamp yarn cop 15 can pivot slightly upward, thus clamp yarn cop Lid 29 is closed and lower yarn 30 is mechanically secured.Clamp yarn cop 15 is pivoted up until before yarn splicing device along dotted line 32.
Once before clamp yarn cop 15 is seated in yarn splicing device together with the received lower yarn 30 of institute, suction nozzle 14 can be received together with institute Upper yarn is switched to a position in the yarn splicing device region in 15 front of clamp yarn cop.
Then, suction nozzle 14 and clamp yarn cop 15 continue to be switched to its respectively final position 33,34, and upper yarn and lower yarn are inserted Enter yarn splicing device.At this point, upper yarn be also inserted into yarn clearer, cutting mechanism and the opening below yarn splicing device clamping and Disconnecting device.Lower yarn 30 is also inserted into the clamping and disconnecting device of yarn splicing device, opening above yarn splicing device.
Upper yarn and lower yarn are inserted into yarn splicing device now and can carry out real yarn engagement.Once carrying out yarn to connect It closes, then clamp yarn cop 15 pivots back to low level again, and in the low level, clamp yarn cop mouthpiece is located at before yarn trend.
