Technical field
A kind of method that the present invention relates to joint of splicing for evaluating the work station place being positioned at the weaving loom producing cross winding bobbin, wherein said work station includes: Yarn twisting device, for by without the end connecting two yarns in the way of tying；Yarn clearer, for monitoring the yarn of traveling；Yarn cutting device, is used for the joint of splicing of fault and the outside tolerable limits cutting in yarn；With control device, and the invention still further relates to for perform the method produce cross winding bobbin weaving loom.
Background technology
In textile industry, widely use the weaving loom of different types of production cross winding bobbin.Except free-end air-flow spinner, for instance, use up-coiler in a large number.
On the different operating station of up-coiler, spinning cop (it originates in ring spinner, and only comprises the raw yarn of relatively small amount) is recoiled to jumbo cross winding bobbin.During recoiling, also monitor from the yarn of spinning cop derivation to find the fault yarn, if it is desired, remove fault.
Each work station of this type of up-coiler is equipped with multiple yarn treatment and processing unit (plant), for instance, yarn tensioner, yarn tension intensity sensor, waxing machine, Yarn twisting device etc., and for monitoring the yarn advanced, also equipped with so-called yarn clearer.
The end of two yarns is linked together by Yarn twisting device, in order to this thread segment with yarn with identical outward appearance reaches outward appearance and intensity.
It addition, multiple work stations all comprise workstation computer, described workstation computer is connected to again the central control unit of weaving loom, it is preferable that pass through bus system.
As such as in DE4028465A1 known and disclosed, yarn clearer is described as a kind of device for measuring thickness and/or weight, this device detection yarn and also detection device of splicer in produce joint of splicing.For this, this yarn clearer generally comprises measurement head, and the yarn that the scanning of this measurement head is advanced is to find scrambling, for instance find slubbing and details.Being operated by property of yarn clearer is connected to yarn cutting device and controls the latter.If the thickness of yarn or joint of splicing or weight outside tolerable limits, so-called Yarn Defect can be cut.Patent disclosed above does not provide any information about the threshold value how inputting yarn clearer.
Generally, the sensitivity of yarn clearer can regulate on the central control unit of weaving loom, say, that can intensively make a reservation for one and irregular whether can be classified as a fault.Except yarn diameter, the length of slubbing and details is also contained in the evaluation of Yarn Defect.Owing to exceeding the tolerance limit limited, be identified once irregular and be classified as Yarn Defect, then yarn clearer performs the cutting of so-called clearing.
EP1235071A1 describes a kind of tearing and/or the method for tensile property for test yarn.Tear test is incorporated in manufacturing process, from without manually removing to measure in the lab from production process by yarn.The method can also be used for test and splices joint.For this, this yarn moves as far as splicing a little between traction apparatus and cross winding bobbin afterwards splicing.According to the method, can the fault of earlier identified splicer.EP1235071A1 does not point out joint of splicing to be checked is selected.
Device according to EP1235071A1 have drawbacks in that each work station of equipment is complicated and thus is expensive.The method and device all do not use in practice.
In order to check on the quality, the outward appearance of joint of especially splicing and intensity, common way is to be removed from manufacturing process by joint of splicing, and is placed in so-called sample or sample card and carries out offline inspection.Manual interruption manufacturing process immediately after splicing.
So each joint is removed from manufacturing process, or operator by sample card visually determine which splice joint need remove.
Traditional method have drawbacks in that when removing and the joint when described joint of splicing is cut from yarn of splicing of detection outside tolerable limits, inefficiency.
Summary of the invention
On above-mentioned prior art basis, the basic goal of the present invention is the efficiency improved and detect joint quality of splicing.
By the feature of the feature of the method for a first aspect of the present invention and the weaving loom producing cross winding bobbin of a second aspect of the present invention, realize above-mentioned target.
According to the first aspect of the invention, in order to realize this target, it is detected as acceptable joint of splicing by the cutting of described yarn cutting device so that the joint of splicing of cutting easily can be removed by operator, and shows that such yarn cuts.
By this way, it is ensured that from manufacturing process, remove the joint of splicing that only will not cut under normal circumstances from yarn, for checking further.In the manufacturing process of " normally ", continue to cut from yarn to be detected as unacceptable joint of splicing, and remove it.Only acceptable joint of splicing can be gone this fact moved to have two major advantages: on the one hand, only these joints of splicing are placed in sample or sample card and test its intensity, described in joint of splicing can retain in the yarn under normal circumstances and be wound on cross winding bobbin and consign to client；On the other hand, it is placed in the joint of splicing on sample card by visual assessment, the setting of yarn clearer can be assessed.If the joint of splicing on such as sample card is too slightly or too thin, this show yarn clearer be conditioned tolerance is bigger.
According to the second aspect of the invention, described control device is set to control described yarn cutting device, make described yarn cutting device cutting joint of splicing in predetermined tolerance limit with joint of splicing described in can easily removing, and display device is controlled such that described display device indicates the cutting of such yarn.
It is an advantage of the current invention that: can control device selects detection to splice joint option program.If owing to beyond predetermined tolerance limit, irregular identified and be classified as Yarn Defect, then yarn clearer triggers the cutting of so-called clearing as usual, and removes Yarn Defect.But, if the joint of splicing in predetermined tolerance limit is through yarn clearer, during joint option program is spliced in detection, also by described joint cutting of splicing.
If spliced, joint is identified as poor, and the thread segment generally carrying out cutting and being correlated with after about 15 centimetres siphons away.If spliced, joint is detected as better, it is necessary to perform clearing cutting, to guarantee relatively easily to be removed joint of splicing by operator.In test, it has been determined that: it is particularly advantageous for cutting acceptable joint of splicing after about 100 centimetres.But, the present invention should not be so limited to this size, because according to machine type, it is possible to the such as clearing cutting for regulation realizes other possible dimensions.
When the cutting of this type of clearing triggers, also control the already present advertiser of each work station.Then work station launches signal, for instance yellowish green flash of light, this yellowish green flash of light teaching process person: cut acceptable joint of splicing here, and joint of splicing described in can removing.
Control the described control device of described yarn cutting device both central control unit, workstation computer or the control unit that is integrated in yarn clearer.It is connected with each other by bus system because each controls device, for instance, it is possible to record is write in central control unit, and as required, described central control unit controls each workstation computer or yarn cutting device.
