Abstract

The utility model relates to a spinner laser yarn warp and weft stop motion monitor, which is characterized in that a semi-conductor laser is adopted as a launch-head light source of a monitor, and not only has all the advantages of the infrared and luminous diode light source such as long service life, small size, low power consumption, high reliability and low cost, but also has high focus and the properties of the visible light, and can omit or simplify the optical focusing parts of the launching head and the receiving head, and can directly observe the debugging of the best alignment of the laser of the launching head and the receiving head, and can greatly improve the affecting distance of the laser; the receiving head is of a conventional photoelectric sensing part, and the monitor circuit has the technical measures for resisting the interference of the color spectrum except the laser and the influence from the external sunlight and the lamination light, so as to ensure the reliability and stability of the continuous work for a long period of time; moreover, the warp and weft stop motion monitor can be widely applied to the major equipments in the textile industry, the silk weaving industry and the chemical fiber industry.

Description

Weaving loom laser yarn broken warp, Weft stop watch-dog

Technical field

The utility model relates to a kind of weaving loom yarn broken warp, Weft stop watch-dog, relates in particular to a kind of laser yarn broken warp, Weft stop watch-dog.This laser yarn broken yarn, broken string automatic stop monitor can be used for the multiple textile machines such as banding machine, spinning machine, loom, warp knitting machine, various warping machiness of textile mills, also can be used for the various device of silk weaving, chemical fibre factory.

Background technology

In textile industry, the warp of various frame yarns, the staplings of parallel, cracked ends monitoring all adopt incandescent lamp, infrared light supply to detect, because service life of incandescent lamp is short, caloric value is big, is progressively replaced by infrared ray; Semiconductor infrared ray advantage is that long service life, volume are little, low in energy consumption, and infrared device reliability height, cost are low etc.But infrared cracked ends, Weft stop watch-dog also have its fatal shortcoming:

1, infrared ray is a kind of black light, be installed in the infrared head of equipment one end and be installed between the infrared receiving terminal of the equipment other end, the aligning of light is very difficult, the aligning of debugging IR is a kind of intuitively non-, only by the other indicator lamp that is provided with of auxiliary circuit, the for example demonstration of Light-Emitting Diode could aim at the infrared light that receives head by indirectly definite emitting head, and it is also uncertain whether to be in best alignment;

2, infrared ray is a kind of scattered light, about 120 degree of scattering angle, must give emitting head, reception respectively the optical focusing system of design specialized make its focusing.And often in machine running process, vibrations, displacement are arranged slightly, emitting head can't be aimed at regard to departing from the infrared light that receives head, give the electrical technology personnel installation, safeguard the harsh requirement of proposition.More obvious for extra long distance equipment such as warp knitting machine, Speed frames, fine spining machine, banding machine, wide cut looms especially.

Data report and actual reflection, infrared light sources is not a preferred plan as broken yarn, the Weft stop monitoring of yarn.

Summary of the invention

A kind of weaving loom yarn broken warp, Weft stop watch-dog, adopt the emitting head light source of semiconductor laser as watch-dog, it not only has infrared ray, the LED source life-span is long, volume is little, low in energy consumption, device reliability height, all advantages that cost is low, the characteristic that has high focusing and visible light again, can omit or simplify the optical focus parts of emitting head and reception head, the laser of direct visual debugging emitting head and reception best an aligning is improved the operating distance of laser greatly; Receive head and be optoelectronic induction device commonly used, monitor circuit has the technical measures that chromatogram is disturbed and extraneous daylight, illuminating ray influence outside the anti-laser, guarantee long-term, the reliability of continuous operation, stability, and can be widely used in warp, the weft yarn watch-dog of all weavings, silk weaving, the most of equipment of chemical fibre industry.

The technical solution of the utility model is:

1, semiconductor laser device is installed in the inside of emitting head, and the photaesthesia optical device is installed in the inside that receives head; The electronic circuit of watch-dog and related device thereof are formed special-purpose supervisory circuit, and make as a whole composition watch-dog assembly; Emitting head with receive the connectivity port separately that head inserts the watch-dog assembly respectively, the control output end mouth of assembly is received cracked ends, the Weft stop appliance controling element of outside, and the sound of electrical control equipment, light warning, display unit;

2, emitting head is installed in a certain end of equipment, receives the other end that head then is installed in equipment.But be anti-electrical Interference, receive head and must adopt anti-interference shielding measure, to guarantee the stability of work.Emitting head also can adopt corresponding anti-jamming circuit and interference protection measure.Emitting head and the line that receives between head and the watch-dog assembly also must adopt shielding line to insert the connectivity port of watch-dog assembly;

3, for the daylight of anti-working site, the light of light disturb, at the front end that receives a light-sensitive device colour filter is installed, the selected color of colour filter should be selected the color of used laser instrument emission, and other useless color of filtering.

Useful effect of the present utility model is:

1, adopt semiconductor laser as cracked ends, staplings watch-dog light source, not only have the life-span long, volume is little, low in energy consumption, all advantages of conventional semiconductor devices such as device reliability height, cost are low, simultaneously laser is a kind of monochromatic visible light, has a splendid focus characteristics again, its emission angle can omit the optical focusing system of emitting head and reception head less than 1 degree; Adopt the range estimation intuitive alignment, greatly omit, simplify first Installation and Debugging and line service, and in case after installing and fixing on machine, substantially no longer optically focused is debugged.All shortcomings that do not have infrared tube, light emitting diode.Be the optimal yarn broken warp of weaving loom, staplings monitoring light source.

2, owing to omitted emitting head, receive the optical focusing system of head, emitting head and the diameter and the length that receive head can be done very for a short time, even little, miniaturization, very are suitable for flying the Weft feeler of staplings such as shuttle, gripper shuttle loom;

3, semiconductor laser be that volume minimum in all laser, cost are minimum, longest-lived, the minimum Laser Devices of heating.And laser is the light source that excitation is the highest, focus characteristics is best in the various up to now light sources;

4, semiconductor laser has extremely pure spectral characteristic, splendid focus characteristics, even in 1 kilometer, can both guarantee not have tangible blooming effect, it is only very suitable on the 2-3 rice weaving loom to be used for conventional equipment length, will inevitably replace cracked ends, the staplings watch-dog of luminescent device mades such as infrared ray and light emitting diode;
