Embodiment Construction
[0015] figure 1 , figure 2 and image 3 The yarn sheet abnormality detection device 1 of the present invention is shown. exist figure 1 Among them, the yarn sheet abnormality detection device 1 is composed of a first abnormality detector 10 , a second abnormality detector 20 and a position calculator 4 in order to detect abnormality of the yarn 3 of the traveling warp yarn sheet 2 . The yarn sheet 2 is composed of a plurality of parallel yarns 3 on a plane, and travels in the direction of the arrow. In this embodiment, the abnormality of the yarn sheet 2 is called the occurrence of hair particles on each yarn 3 .
[0016] In this embodiment, in order to detect the occurrence of fluff as an abnormality of each yarn 3 in progress, the first abnormality detector 10 is constituted by a fluff detector extending along the width direction of the yarn sheet 2, Each end yarn sheet 2 of the sheet 2 is composed of a photoelectric sensor, that is, a first light projector 11, a first ...

This invention provides a yarn sheet abnormality detector which can specify the abnormality position of the yarn sheet in the cross direction, when the abnormality is occurred. This yarn sheet abnormality detector is characterized by comprising the first abnormality detector disposed in the cross direction of the yarn sheet to detect the abnormality of a traveling yarn, the second abnormality detector disposed on at least one of the upstream and downstream sides of the yarn of the yarn sheet in the traveling direction and further disposed in the cross direction of the yarn sheet at a prescribed cross angle to the first abnormality detector, and a position detector for specifying an abnormal position in the cross direction of the yarn sheet on the basis of a time between the abnormality detection signal-outputting time of the first abnormality detector and the abnormality detection signal-outputting time of the second abnormality detector.
Description
technical field [0001] The present invention relates to a device for detecting abnormality of yarn pieces, and mainly relates to a device for detecting abnormality of warp yarn pieces. Background technique [0002] In Patent Document 1 (Japanese Unexamined Patent Publication No. Hei 5-321068), a technology for detecting abnormalities in the direction of travel of the yarn sheet is disclosed; A yarn breakage detector is arranged in the width direction of the yarn sheet to detect the yarn breakage of the yarn sheet. [0003] However, in the above-mentioned Patent Document 1 and Patent Document 2, although the abnormality of the yarn piece is detected, the position where the abnormality occurs in the width direction of the yarn piece cannot be determined at this time, and it takes time to find the place where the abnormality occurs. . Contents of the invention [0004] Therefore, an object of the present invention is to provide a yarn piece abnormality detection device capa...
