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
