The specific embodiment
Below in conjunction with accompanying drawing, to taper of the present invention, the loosening method around fine method is elaborated.
Referring to Fig. 1, the present invention senses loose optical fiber by being located at the inductor 2 of roll of optical fiber 1 below of winding, thereby sends shutdown signal, stops optical fiber around volume.If without finding that optical fiber is loose, be wound around, until reach preseting length always.
In conjunction with Fig. 2, owing to adopting taper around fine method, every layer of optical fiber is all wound around along the periphery of take-up reel tool, and every layer of Optical Fiber Winding number of turns is fewer than lower floor's Optical Fiber Winding number of turns, thereby in both sides, has formed the conical surface 13.As ground floor optical fiber 11 covers whole take-up reel tool, while continuing to be wound around, the winding number of turns of every layer of optical fiber reduces successively, until the periphery of last layer optical fiber 12 in the middle of forming on take-up reel tool while being wound around.Can see from the conical surface 13 situation of each layer of optical fiber thus.
Axis along roll of optical fiber 1 is longitudinally cut open, cross section for be upper and lower two trapezoidal, trapezoidal upper base is last layer optical fiber 12, trapezoidal bottom is ground floor optical fiber 11.The trapezoidal hypotenuse in lower end is defined as lower along the line 14 of the conical surface.
Inductor 2 is two, is located at respectively the below of the left and right sides conical surface 13 by fixed mount 3.Each inductor 2 comprises laser transimitter 22, laser pickoff 23 and signal processor 24.Laser transimitter 22 and laser pickoff 23 are vertical at respectively the both sides, front and back of the conical surface 13 belows, and the edge, upper end 21 of laser transimitter (or laser pickoff) and the conical surface is lower along the line 14 parallel.The laser transimitter 22 of each inductor and laser pickoff 23 are all perpendicular to horizontal surface setting, and vertical dimension is identical, and distance is between the two 15-20cm.Vertical distance between the horizontal surface at the edge, upper end 21 of lower along the line 14 and mistake laser transimitter (or laser pickoff) of the definition conical surface is h.
Because the number of turns of Optical Fiber Winding is successively decreased successively, thus trapezoidal hypotenuse angle being whenever all consistent of Optical Fiber Winding, the winding of optical fiber is the extension process of trapezoidal hypotenuse.While guaranteeing thus under inductor 2 and the conical surface 14 keeping parallelism along the line, when being wound into any one deck optical fiber, during conical surface generation loose ends, can be sensed by inductor 2.
The principle of induction of inductor 2 is: laser transimitter 22 sends laser, and laser pickoff 23 receives and provide signal to signal processor 24.When there is no object between laser emitter 22 and laser pickoff 23; signal processor 24 provides the signal feedback of " 1 " to equipment; if there have object to appear to be middle; the laser that laser pickoff 23 receives will change; the signal (being shutdown signal) that signal processor 24 provides " 0 " feeds back to equipment, requires equipment downtime.
Below in conjunction with specific embodiment, the present invention is further described.
