The specific embodiment
Fig. 1, Fig. 2 and Fig. 3 illustrate Yarn sheet abnormal checking device 1 of the present invention.In Fig. 1, Yarn sheet abnormal checking device 1 is unusual for the yarn 3 that detects the warp thread piece 2 in advancing, and is made of first anomaly detector 10, second anomaly detector 20 and position calculator 4.Yarn sheet 2 is made of many parallel yarns 3 that are positioned on the plane, advances along the direction of arrow, in this embodiment, the generation that is called the card nailing neps on each yarns 3 unusually of yarn sheet 2.
In this embodiment, in order to detect generation as the unusual card nailing neps of each yarns 3 in advancing, first anomaly detector 10 is made of the card nailing neps detector that extends along yarn sheet 2 widths, and promptly first light projector 11, first light-receiving device 12 and controller 13 constitute by the photoelectric sensor of respectively holding yarn sheet 2 tops that is arranged on yarn sheet 2.First light projector 11 the top of each yarns 3 all the time the sender to advance in the light of yarn 3 quadratures, and with this ray cast on first light-receiving device 12.First light-receiving device 12 is transformed into signal with the proportional level of light income of light with the light of being accepted, and is sent to controller 13.If produce card nailing neps on any yarns 3 in yarn sheet 2, this card nailing neps just covers or reduces the light that incides first light-receiving device 12.Like this, controller 13 will be compared with reference level from the signal level of first light-receiving device 12, when being judged as the generation card nailing neps because of signal level decline, unusual detection signal S1 will be sent to position detector 4.
In order to detect generation as the unusual card nailing neps of each yarns 3 in advancing, in the upstream or the downstream of direct of travel that with first anomaly detector 10 is the yarn sheet 2 of benchmark, width along yarn sheet 2 is provided with second anomaly detector 20, with respect to 10 one-tenth regulations of first anomaly detector angle theta.Identical with first anomaly detector 10, second anomaly detector 20 also is made of the card nailing neps detector, is made of the 2nd light projector the 21, the 2nd light-receiving device 22 and controller 23.The 2nd light projector 21 sends the light with respect to the 3 one-tenth angle theta of yarn in advancing all the time on the top of each yarns 3, and with described ray cast to second light-receiving device 22.Second light-receiving device 22 is transformed into signal with the proportional level of light income with the light of being accepted, and sends to controller 23.If produce card nailing neps on any yarns 3 of yarn sheet 2, this card nailing neps covers or reduces the light that projects second light-receiving device 22.Like this, controller 23 will be compared with reference level from the signal level of second light-receiving device 22, when being judged as the generation card nailing neps because of signal level decline, anomaly detection signal S2 will be sent to position detector 4.
As shown in Figure 2, as required, upstream side and downstream at the direct of travel of the yarn sheet 2 of first anomaly detector 10 and second anomaly detector 20,14,15 and 2 pogo sticks 24,25 of 2 pogo sticks are set, make the lower surface of its contact yarn sheet 2, and see that from above they are clipped in the middle the light of first light projector 11, the light of second light projector 21 respectively.14,15 and 2 pogo sticks 24,25 of these pogo sticks make the card nailing neps that occurs in the downside on the yarn 3 hold up towards the top, thereby can make card nailing neps cover the light of first light projector 11 and the light of second light projector 21 really effectively.
If in yarn sheet 2 is advanced, card nailing neps appears on any yarns 3, and at first first light-receiving device 12 detects its card nailing neps, and second light-receiving device 22 detects same card nailing neps then.Because the light of first anomaly detector 10 (first light projector 11) and the light of second anomaly detector 20 (second light-receiving device 21) form angle theta, so detecting card nailing neps since first light-receiving device 12 differed from one another because of the occurrence positions of card nailing neps on the width of yarn sheet 2 to the time that second light-receiving device 22 detects till the same card nailing neps, end at the yarn sheet 2 of angle theta side shortens, and along with the end near the yarn sheet 2 of anti-angle theta side is elongated pro rata.Thus, according to the abnormality detection of first anomaly detector 10 constantly and the time of the abnormality detection of second anomaly detector 20 between constantly, just can determine the out-of-the way position on yarn sheet 2 widths, for example apart from the out-of-the way position of the end of the yarn sheet 2 of angle theta side.
On the direct of travel of yarn 3, suppose that the distance from the light of first light projector 11 to the light of second light projector 21 is L, the speed of yarn 3 is V, enter the required time of position of the light of second light projector 21 from the position row of the light of first light projector 11 as unusual card nailing neps, in other words, the time that is carved into during from the unusual detection of first anomaly detector 10 between the unusual detection constantly of second anomaly detector 20 is T, and between them, calculating formula L=VT sets up so.Here, for whole yarn 3, because speed V is identical value, can measure out, actual measurement be carved into the time T between the unusual detection constantly of second anomaly detector 20 during from the unusual detection of first anomaly detector 10, just can try to achieve distance L.And can determine from the out-of-the way position X of the width of yarn sheet end to end by this distance L.This out-of-the way position X and unusual occurrence positions are that the yarn 3 of occurrence positions of card nailing neps is corresponding.
What Fig. 3 represented is the curve map of out-of-the way position X with respect to time T, wherein in the width of yarn sheet 2, getting out-of-the way position X is transverse axis, be carved into when getting from the detecting of the card nailing neps of first anomaly detector 10 second anomaly detector 20 identical card nailing neps to detect time T constantly be the longitudinal axis.The slope of a curve is here determined by angle theta.Like this, if obtain time T, just can determine the out-of-the way position X corresponding (occurrence positions of card nailing neps) simply with time T from curve.Though also can represent this out-of-the way position X (occurrence positions of card nailing neps) to the range data of the direction of the other end with a end from yarn sheet 2, but usually as shown in Figure 3, the width of yarn sheet 2 is divided into several parts, as 10 parts, with numerical value 1,2 ... 10 the expression these cut apart scope, perhaps with light corresponding to the numerical value 1,2 of cutting apart scope ... 10 lamp is represented.
Yet in yarn sheet 2 was advanced, when card nailing neps had taken place certain yarns 3, at first first anomaly detector 10 detected this card nailing neps, and output comes the detection signal S1 of self-controller 13.Then, second anomaly detector 20 detects same card nailing neps, and output comes the detection signal S2 of self-controller 23.If these detection signals S1, S2 is input to position detector 4, when the calculator 6 in the position detector 4 is gone out the signal that goes out now to the signal of detection signal S2 now and time difference occurred and obtain time T by the signal from detection signal S1 so, detect the speed V of yarn 3 from the rotating signal S3 of the encoder 7 that is connected with deflector roll 8 grades of yarn sheet 2, L=VT obtains distance L by calculating formula, determine the out-of-the way position X (occurrence positions of card nailing neps) of the width of yarn sheet 2 according to this distance L, will the video data corresponding be sent to the display 5 in the position detector 4 with this out-of-the way position X.Because the speed V of yarn 3 is certain basically when running well, and is redefined for certain value so also can not measure.
Here, display 5 will be corresponding with out-of-the way position X video data (counting distance) to other end direction from an end of yarn sheet 2 be presented on the picture with literal or figure, perhaps as shown in Figure 3, with numerical value 1,2 ... 10 grades represent yarn sheet 2 width cut apart scope, perhaps light with cut apart scope numerical value 1,2 ... the lamp of 10 correspondences is by changing color or lighting display abnormality position X (occurrence positions of card nailing neps) such as position.Thereby the operator can easily confirm the occurrence positions of card nailing neps from the displaying contents of the out-of-the way position X of display 5.
Calculator 6 generates location stop signal S4 behind the moment process official hour that receives detection signal S1, not shown traveling drive is stopped.Therefore, card nailing neps is found in the position corresponding to the downstream of the displacement of official hour the occurrence positions that is provided with of first anomaly detector 10 can left.Certainly since time of afore mentioned rules must be after second anomaly detector 20 detects card nailing neps, so will be set greatlyyer than maximum time T.
First anomaly detector 10 and second anomaly detector 20 also can be made of the yarn break detector that forms search coverage on yarn sheet 2 widths below yarn sheet 2.Yarn break detector is the same with the card nailing neps detector, is made of photoelectric sensor, detects the broken end of bringing in detection yarn 3 because of the sagging yarn of Yarn break.
Next, Fig. 4 illustrates along the width mark section of yarn sheet 2 and for example divides 2 sections embodiment that first anomaly detector 10 and second anomaly detector 20 are set.According to such embodiment,,, also can easily determine out-of-the way position so can improve accuracy of detection because the scope of respectively cutting apart of yarn sheet 2 is detected respectively by the Yarn sheet abnormal checking device 1 of correspondence.Part beyond first anomaly detector 10 and second anomaly detector 20 can be shared.
In addition, Fig. 5 represents is that Yarn sheet abnormal checking device 1 is installed in embodiment on the warping machines 9.Here, yarn sheet 2 is warp thread pieces, and yarn 3 is warp thread.Warp thread is sent from warping machines 9, through the position of 2 deflector rolls 17,18 by Yarn sheet abnormal checking device 1, is rolled onto on the warp shaft 16 by deflector roll 19.
Yarn sheet abnormal checking device 1 of the present invention is except the yarn sheet 2 that is applicable to warping machines, also applicable to the yarn sheet 2 of Sizing machines etc.And the present invention also can implement aforesaid each embodiment appropriate combination.
