Abstract

PURPOSE: To obtain the subject optical device capable of detecting break down of all kinds of crude yarns in the region of a drafting device containing twisting back of the crude yarn by providing plural optical systems in horizontal direction and vertical direction for photoelectronic monitoring of a crude yarn in a flier. CONSTITUTION: This optical device having a receiver and a transmitter and monitors a crude yarn 3 in a photoelectronic manner and provides a horizontal optical system 4 and a vertical optical system 5, then a light in the horizontal optical system is interrupted by drooping the crude yarn 3 downward when the crude yarn 3 is broken between a drawing out roller and a winding device to stop the machine. In the case, the light 4 is provided under the crude yarn 3 in considering to a maximum drooping (a) of the crude yarn generable in the crude yarn spinning technique. Even after passing several times, the crude yarn 3 is eliminated and by the interruption of yarn material in the region of the drafting device, then the machine is stopped without interruption of the light in vertical direction.

In order to monitor the roving photoelectrically, it is known to evaluate the fall of the roving through the optical system, and on the other hand, from East German Patent No. 266 659, it is known to evaluate the presence of the roving in the optical system. known to evaluate. The disadvantage here is that the known technology does not allow all types of roving breaks to be identified.

垂直光学系が機械を停止させることはない。In this embodiment, a vertical optical system and a horizontal optical system are provided, each with a receiver 1 and a transmitter 2. 9 A pay-out roller and a winding device (not shown) are provided between the roving 3 and the device. Due to the breakage, the roving 3 hangs downward and blocks the light beam 4 of the horizontal optical system. In that case, ray 4 is
It is provided below the roving yarn 3, taking into account the maximum sag a that can occur in roving technology. In this case, the light beam 5 of the vertical optical system is not blocked when the roving 3 falls, so
Vertical optics do not stop the machine.
