Title: Bobbin winder for cross wound bobbins has an optic fiber monitor at the yarn guide roller to carry light between a transmitter and receiver with an interruption if yarn has wound itself around the roller
Inventor: FECHTER ULRICH
IPC: B65H63/00
Filed: 1999-09-02
Abstract: The bobbin winder has an optical monitor system to detect irregular winding at the guide roller, with an optic fiber (27,27') at the yarn guide roller (23), to take the transmitted light from the light transmitter (30) and carry it onwards to the light receiver (26) if there is no winding fault. On an irregularity in the yarn winding where the yarn winds itself around the roller, the light path is interrupted between the light transmitter (30) and receiver (26). The light source (30) transmits infra red light. The optic fiber is laid in two sections, where the first section is aligned on the radial direction of the yarn guide roller and the second section runs axially from the end of the first optic fiber section to the end of the roller. The entry for light into the first optic fiber section is shrouded by any irregular yarn winding around the roller. The yarn guide roller has a yarn guide groove to take the yarn, and the light entry into the first optic fiber section is at the base of the yarn guide groove. The optic fiber sections (27,27') can be aligned axially through the yarn guide roller (23), interrupted by the yarn guide groove (24), and the light transmitter (30) at one end is aligned axially with the receiver (26) at the other end. The light receiver (26) is connected to an evaluation unit (28) which determines that the bobbin winding is faulty if no signals are received from the light receiver within a given number of yarn guide roller rotations, and stops bobbin winding. The optic fiber structure is formed by drillings which are filled with a light-conductive plastics.
