Abstract

A találmány tárgya berendezés fonal (2, 9) hibáinak felismerésére,amelynek átlátszó görbült felülete (5), a fonalat (2,9) az átlátszógörbült felületen (5) csúsztató vonóeszköze, az átlátszó görbültfelülettel (5) társított optikai érzékelője (8) és fénykibocsátóeszköze (7), továbbá az optikai érzékelőhöz (8) kötött, afénykibocsátó eszköz (7) által a fonalnak (2,9) az átlátszó görbültfelületen (5) keresztül az optikai érzékelőre (8) vetített árnyékátkövető és elemző, hiba észlelésekor a vonóeszköz leállítását és afonal (2, 9) elvágását működésbe hozó számító egysége van. A találmányszerinti berendezésben az optikai érzékelő (8) és a fénykibocsátóeszköz (7) az átlátszó görbült felület (5) ellentétes oldalán vanelrendezve, és az átlátszó görbült felület (5) és az optikai érzékelő(8) között a fonalra (2, 9) nézve keresztirányban egy, ahibafelismerés pontosságát növelő rés (17) van elrendezve. A találmánytárgya továbbá eljárás fonalhibák gyártásközi felismerésére a fentiberendezéssel. ÓThe subject of the invention is a device for detecting defects in a yarn (2, 9), which has a transparent curved surface (5), a traction device for sliding the yarn (2, 9) on the transparent curved surface (5), an optical sensor (8) associated with the transparent curved surface (5) and light emitting device (7), and the shadow transmitted and analyzed by the light emitting device (7) connected to the optical sensor (8) of the yarn (2,9) through the transparent curved surface (5) onto the optical sensor (8), stopping the traction device when an error is detected and afonal (2, 9) has a computing unit that makes it work. In the device according to the invention, the optical sensor (8) and the light emitting device (7) are arranged on opposite sides of the transparent curved surface (5) and between the transparent curved surface (5) and the optical sensor (8) in view of the yarn (2, 9) a gap (17) that increases the accuracy of fault detection is arranged in the transverse direction. The subject of the invention is also a method for mid-production recognition of yarn defects with the above equipment. HE
