Background technology
In textile industry, the weaving loom of different types of production cross winding bobbin is widely used.Except free end air-flow
Outside spinning machine, for example, largely using up- coiler.
On the different operating station of up- coiler, (it originates in ring spinner to spinning cop, and includes only relatively small amount
Raw yarn) it recoils to the cross winding bobbin of large capacity.During recoil, yarn is also monitored derived from spinning cop to look for
To the fault in yarn, if it is desired, removal fault.
Each work station of such up- coiler is equipped with multiple yarn treatments and processing unit (plant), for example, yarn tensioner, yarn
Line tension intensity sensor, waxing machine, Yarn twisting device etc., and the yarn advanced for monitoring are also equipped with so-called clear
Yarn device.
Yarn twisting device links together the end of two yarns, so as to this yarn with yarn appearance having the same
Line part reaches appearance and intensity.
In addition, multiple work stations include workstation computer, the workstation computer is connected in weaving loom again
Control unit is entreated, bus system is preferably passed through.
As known to for example in DE4028465A1 and disclosed, yarn clearer be described as it is a kind of for measure thickness and/
Or the device of weight, the device detect yarn and also detect the connector of splicing generated in device of splicer.For this purpose, the yarn clearer one
As include measurement head, the yarn that measurement head scanning is advanced is to find scrambling, such as finds slubbing and details.Yarn clearer is logical
It crosses to be operatively connected and is connected to yarn cutting device and control the latter.If the thickness or weight of yarn or connector of splicing are beyond public affairs
The poor limit can cut so-called Yarn Defect.The above-mentioned published patent does not provide any on how to inputting the threshold of yarn clearer
The information of value.
In general, the sensitivity of yarn clearer can be adjusted on the central control unit of weaving loom, that is to say, that can be intensively
Whether predetermined one irregularly can be classified as a fault.Other than yarn diameter, the length of slubbing and details is also contained in yarn
In the evaluation of fault.Due to the tolerance limit beyond restriction, once irregular be identified and be classified as Yarn Defect, then yarn clearer is held
The so-called clearing cutting of row.
A kind of method that EP1235071A1 describes the tearing for test yarn and/or tensile property.By tear test
It incorporates in manufacturing process, without manually removing yarn to measure in the lab from production process.This method
It can be used for testing connector of splicing.For this purpose, the movement after splicing of this yarn is a little located at draft gear and cross winding as far as splicing
Between bobbin.According to the method, can earlier identified splicer failure.Do not pointed out in EP1235071A1 to it is to be checked splice connect
Head is selected.
It is according to the shortcomings that device of EP1235071A1：Equip each work station be it is complicated and thus be expensive
's.This method and device do not use in practice.
In order to check on the quality, the appearance and intensity of joint of especially splicing, common way are will to splice connector from system

According to the first aspect of the invention, it in order to realize the target, is detected as by yarn cutting device cutting
Acceptable connector of splicing so that the connector of splicing of cutting can easily be removed by operator, and show that such yarn is cut
It cuts.
In this way, ensure that splicing of will not only being cut under normal circumstances from yarn is removed from manufacturing process to be connect
Head, for further checking.In the manufacturing process of " normal ", continuation cut from yarn be detected as it is unacceptable splice connect
Head, and remove it.Only acceptable connector of splicing can be gone to move the fact that there are two major advantage:On the one hand, only
These connectors of splicing can be placed in sample or sample card and test its intensity, and the connector of splicing can be retained in yarn under normal circumstances
In line and it is wound on cross winding bobbin and consigns to client；On the other hand, the twirl being placed in by visual assessment on sample card
Connector can assess the setting of yarn clearer.If such as the connector of splicing on sample card is too thick or too thin, this shows yarn clearer
Be conditioned tolerance is larger.
According to the second aspect of the invention, the control device is set to control the yarn cutting device so that institute
It states yarn cutting device cutting and splices connector in predetermined tolerance limit can easily remove the connector of splicing, and show
Showing device is controlled such that the such yarn cutting of the display device instruction.
The advantage of the invention is that：It can select to detect connector option program of splicing on control device.If due to
Irregular to be identified and be classified as Yarn Defect beyond predetermined tolerance limit, then yarn clearer triggers so-called clearing cutting as usual, and
Remove Yarn Defect.However, if in predetermined tolerance limit splice connector pass through yarn clearer, detection splice connector selection
During program, also by the joint cutting of splicing.
If connector of splicing be identified as it is poor, usually carried out after about 15 centimetres cutting and relevant thread segment inhale
It walks.If connector of splicing is detected as preferably, it is necessary to clearing cutting is executed, to guarantee relatively easily to be removed by operator
Splice connector.In experiment, it has been determined that：Acceptable connector of splicing is cut after about 100 centimetres to be particularly advantageous.So
And the present invention should not be so limited to the size, because according to machine type, also may be, for example, the cutting of defined clearing realize it is other can
Row size.
When such clearing, which is cut, to be triggered, the already present signal device of each work station is also controlled.Then work station emits
Operator is informed in signal, such as yellowish green flash of light, the yellowish green flash of light：Here acceptable connector of splicing has been cut, and can have been gone
Except the connector of splicing.
Control the yarn cutting device the control device both can be central control unit, workstation computer or
The control unit being integrated into yarn clearer.Because each control device is connected with each other by bus system, for example, can will record
It is written in central control unit, and as needed, the central control unit controls each workstation computer or yarn is cut
Cut device.
