Description
Technical field
The utility model relates to a kind of spinning machine monitor, especially a kind of high speed fibre spinning machine laser yarn watch-dog.
Background technology
Textile industry is the important industry that is related to China's people's livelihood, is also to have the industry that long history is traditional.
The spinning machine of Yi Ge textile enterprise occupies the major part of these all Weaving devices of enterprise, and the owning amount of spinning machine and spindle sum thereof indicate the production scale of this enterprise, determine it in the sector institute in what status.
China is world textile big country, thereby national spinning machine owning amount is very huge.Spinning machine mainly includes two kinds of Speed frames, fine spining machines, particularly high speed bobbiner, fine spining machine.
Under high-speed cruising, the occurred vibrations, the mechanical part of complexity runs up due to the inhomogeneities of sliver, all may have influence on yarn qualities at any time, once yarn broken string on certain spindle of generation spinning machine, can cause a large amount of defective product and waste, so thread monitor becomes the very crucial equipment of spinning machine, the broken end number conventionally occurring with thousand ingots hour represents end breakage rate.The height of end breakage rate affects again labor productivity, equipment productivity, spinning machine quality and workshop dustiness.
Monitor in the past yarn broken yarn and adopt machinery-electrical contact mode to survey the work operation conditions of each one thread, once broken string just sends alarm signal, notify operating personnel to process in time.But because the flyings of spinning and weaving workshop cotton are more, often cause the loose contact of electrical node, this machine-electric watch-dog just performs practically no function in the course of time, not effect; Generally adopted now light emitting diode, infrared diode as spinning machine yarn broken yarn watch-dog, than electromechanical watch-dog, had very large improvement, mistake control rate alleviates greatly.But because general spinning machine has tens meters of long distances, light emitting diode, infrared diode are scattering light source, to be extremely difficult keeping superfine light to detect superfine yarn between tens meters of extra long distances, even if adopt the optical focus camera lens of complex precise to be also difficult to reach yarn testing requirement.Again, infrared diode light source belongs to non-visible light source, also non-visible light will be converted to visible ray and just can reach perusal, find whether broken yarn fault of yarn.According to our research and development and practical application, draw: in all light sources, unique only have semiconductor laser light resource can become spinning machine the best yarn detection light source.Semiconductor laser diode volume is little, low in energy consumption, visible ray, can really solve spinning machine yarn broken yarn test problems, also can make various high speed bobbiners, fine spining machine yarn broken yarn monitor apparatus.
Summary of the invention
A laser yarn watch-dog, adopts visible light semiconductor laser, and its laser beam emitting head and laser pick-off head are arranged on respectively head, the tail two ends of high speed fibre spinning machine, and laser yarn watch-dog is arranged on spinning machine electric control box; Laser beam emitting head and laser pick-off head are that metal material is made, and its end face has dustproof eyeglass, and there is anti-external interference light source light-absorption layer inside; Semiconductor laser diode is arranged in laser beam emitting head, and photodiode is arranged in laser pick-off head; Laser beam emitting head, a laser pick-off holding wire and power line are linked into respectively laser yarn watch-dog, and inner reliability, the accuracy that adopts data encoding-decoding technique to guarantee Laser emission and reception of laser yarn watch-dog, only has and work as
laserthe data decode signal that the coded data signal that emitting head sends and laser pick-off head the receive Shi Caineng that is consistent performs an action, and the concurrent visual alarm of speaking, prevents the misoperation that ambient light is disturbed and electrical Interference signal produces.
The technical solution of the utility model is:
1, adopt semiconductor visible laser as emitting head and the Receiver of spinning machine watch-dog, laser beam emitting head and laser pick-off head are arranged on spinning machine head, tail two ends light thread monitor is arranged on spinning machine electric control box.
2, laser beam emitting head and laser pick-off head are metal material, and its end face has dustproof eyeglass, the included color filter of dustproof eyeglass of laser pick-off head, and color filter is consistent with laser emission spectrum frequency, with other useless spectrum of filtering; In the cavity of laser beam emitting head and laser pick-off head, have anti-light to disturb light-absorption layer, laser beam emitting head, a laser pick-off holding wire and power line are linked into laser yarn watch-dog, and laser yarn watch-dog is arranged on spinning machine electric control box.
3, laser yarn watch-dog adopts light-data encoding technique and circuit to prevent optical, electrical interference, makes that laser monitor device is reliable, steady operation, external sound, the light warning device of laser monitor device.
Useful effect of the present utility model is:
1, due to the collimation of semiconductor laser light resource, at tens meters, even within hundreds of rice, remain a branch of visible light beam less than 2-3mm, the scattering problems that has overcome light emitting diode, infrared diode completely, makes the LASER Light Source become unique, the desirable light source of spinning machine.
2, due to the collimation of semiconductor laser light resource, and superfine light beam, laser pick-off head, emitting head optical lens are very simplified, aim at, light is debugged to work simplification, once and debugging aims at, substantially can realize and exempt from debugging, reliability and over a long time job stability are guaranteed.
3, because workshop light source is spuious, fluorescent tube is more, the anti-ambient light of laser beam emitting head and Receiver is disturbed extremely important, adopt light-data encoding technique and circuit, only have when laser pick-off head is consistent with emitting head signal code effective, even if receive and the identical extraneous visible ray of laser spectrum frequency, also rejection; In Receiver-emitting head inside, be provided with anti-light and disturb light-absorption layer, effectively prevent optical, electrical interference.
