Description
Technical field：
The invention belongs to sensor technical field of weaving, more particularly to a kind of yarn Ultra-Low Speed intermittent movement sensor and
Its method of work.
Background technology：
Warp knit lace fabric is exactly careful exquisite with the gorgeous complicated changeable, pattern of itself flower pattern and be subject to consumers in general
Favor, but weave complicated design and but come very big to the flame broken yarn detection band in lace fabric production process
Difficulty, this is because pattern different on warp knit lace fabric be by different flames complete weave, due to
Decorative pattern also can be converted significantly in a colored high circulation so that different flames completes each difference decorative pattern volume
Thread-feeding amount when knitting in each row may all occur acute variation, and some row band yarn numbers need greatly flame quickly defeated
Yarn, some row band yarn numbers are that zero flame almost stops defeated yarn, and flame shows during normal braiding
The extremely low motion feature of the defeated yarn speed of the obviously defeated yarn of clearance-type, and some row sections.
Complicated design background so that the workman that keeps off a car is difficult to identify that the lace produced on machine is produced with naked eyes
There is broken yarn float on product, often wait until that defective product could be found into perching link after dyeing and finishing, and now because caused by broken yarn
Loss cannot be retrieved.For the detection of broken yarn on textile machine is frequently with infrared electro circuit wire sensor, it utilizes yarn
Filoplume during quick motion on yarn carries out high frequency cutting, and then the pulse signal of generation certain frequency to detecting light beam, works as arteries and veins
The frequency for rushing signal is less than after certain value, that is, think yarn stop motion, and for flower in the production process of warp knit lace fabric
This broken yarn that there is Ultra-Low Speed intermittent movement feature of formula yarn, at present existing circuit wire sensor can be in yarn in ultralow
Speed motion or batch (-type) are reported yarn breakage by mistake and are shut down when stopping defeated yarn, it is impossible to effectively detected.
The information for being disclosed in the background section is merely intended to increase the understanding of the general background to the present invention, and should not
When the prior art for being considered to recognize or imply in any form the information structure well known to persons skilled in the art.
The content of the invention：
It is an object of the invention to provide a kind of yarn Ultra-Low Speed intermittent movement sensor and its method of work, so as to gram
Take above-mentioned defect of the prior art.

Have detection circuit, " U " type groove be provided with the sensor main body, be provided with " U " type groove a pair of infrared emittings with
Reception pipe, the rotating shaft two ends are fixed in " U " type groove by bearing block, and the lightweight grating disc, yarn are set with around wheel
In rotating shaft；The lightweight grating disc is gone out the dense grid ring of certain amount for one week around its core by laser engraving, when yarn around
Wheel drives axis of rotation, lightweight grating disc to rotate, and dense grid ring cutting cuts the detection light beam of Infrared emitting and receiving pipe formation.
Preferably, in technical scheme, yarn is " V " sheave around wheel, is easy to yarns loop and prevents yarn from slipping.
Preferably, in technical scheme, the diameter >=3 times yarn of dense grid ring is around the diameter taken turns.
Preferably, in technical scheme, the detection circuit inside sensor main body leaves broken yarn in sensor main body case
Signal output lag time adjusts knob, when suitable corresponding time delay is arranged according to the different yarns different minibreak cycle
Between.
Preferably, in technical scheme, three color relay indicating lights are provided with sensor main body, are shown during yarn motion state
Green, shows redness during broken yarn state, retardation shows yellow during the period.
A kind of method of work of yarn Ultra-Low Speed intermittent movement sensor, its step is：
(1) axis of rotation is driven after " V " shape groove surround movement of the yarn along yarn on wheel, and then drives lightweight grating disc
Rotation so that the dense grid ring cutting on lightweight grating disc cuts the infrared detection formed by a pair of Infrared emitting and receiving pipes
The pulse sequence signal of corresponding frequencies is produced in light beam, and then the detection circuit in sensor main body；
(2) dense grid ring with diameter greater than yarn around wheel diameter, and grid is intensive, even if when yarn is with extremely low speed
During degree operation, the linear velocity of yarn also by because yarn it is many with what the rotating ratio of dense grid ring and grid number were brought around wheel
Multiplying power is amplified, and causes dense grid ring cutting to cut knowledge of the frequency higher than electronic device that detection light beam forms pulse sequence signal
Other lower limit, so as to identify motion state of the yarn under extremely low speed, now three color relay indicating lights show green, output circuit
Output yarn normal signal；
(3) when yarn seizes up state, dense grid ring no longer cuts detection light beam, now pulse sequence signal
Frequency is 0 or less than a certain minimum threshold values, and sensor main body internal detection circuitry starts start-up study timing, and timing is logical
Cross the time span of broken yarn signal output lag time adjustment knob setting, during timing is not completed, three color relay indicating lights
Yellow is shown, output circuit still keeps exporting yarn normal signal；If detecting pulse sequence signal frequency before timing is completed
Rate recovers normal, then stop and cancel timing immediately, and three color relay indicating lights recover to show green；If timing completed and
Pulse sequence signal frequency is still 0 or during less than a certain minimum threshold values, then three color relay indicating lights show red, and output circuit
Output yarn broken yarn signal, expression now has been acknowledged yarn exception.
Compared with prior art, the present invention has the advantages that：
Amplify the frequency of pulse sequence signal when the low linear velocity of yarn is run by increasing grating disc cutting grating, it is ensured that
Identification of the circuit to low-speed run state；Adjustable function is exported by increasing broken yarn signal lag, yarn can be avoided in clearance-type
Minibreak state lower sensor broken yarn wrong report.Deft design of the present invention, it is easy to accomplish, further widen existing photoelectricity
The application places and applicable object scope of fracture of wire detection technique.
