Abstract
The invention discloses a broken yarn detection mechanism. The mechanism comprises a steel collar, a steel traveler and a photoelectric sensor, wherein a ring of convex edge is formed on the top of the steel collar, and the steel traveler is connected with the edge in a sliding manner; the photoelectric sensor comprises a transmission end and a receiving end; the transmission end transmits light to the edge, and when the steel traveler passes a reflection zone, the light transmitted from the transmission end is reflected by the steel traveler and then received by the receiving end; and during the normal work of the mechanism, the frequency of signals received by the receiving end is a constant value which is equal to the number of turns of the steel traveler on the steel collar per second. If a yarn is broken, the traction function of the yarn to the steel traveler disappears, and the velocity and the frequency of movement of the steel traveler on the steel collar decrease greatly under the action of friction. By virtue of the detection manner, the time of detection on the broken end of the yarn can be shortened greatly, and the yarn can be connected timely and conveniently by a worker.
Description
Technical field
The present invention relates to the Weaving device technical field, especially relate to a kind of for the broken yarn testing agency on the fine spining machine.
Background technology
Fine spining machine be in the spinning process semi-products rove or strip through drawing-off, twist, be wound into the Spining Robot of spun yarn cop.Broken yarn appears in fine spining machine easily in twisting process.
Traditional broken yarn testing agency is by two kinds: mobile detection mode is gone the rounds in a kind of employing, to establish in the ring rail front side runway is installed, a magnetoelectric transducer is installed on the runway, induce the turn signal of a steel traveler that respectively splits by mobile magnetoelectric transducer, and by wire with signal in central processing unit, to detect each ingot position breakage situation.But owing to need runway to be mounted in the front portion of ring rail, and the existence of runway all drives inconvenience for manually-operated and cleaning, especially a magnetoelectric transducer detects the steel traveler of each ingot position in moving process, owing to up to a hundred spindles are installed on the locomotive, so magnetoelectric transducer can not in time be found the ingot position of Yarn break and send the broken yarn signal.
Another is to adopt sensor to detect the method for rings runway temperature, and in the time of the fine spining machine normal operation, steel traveler is along rings runway High Rotation Speed, and the friction between steel traveler and the rings is so that the temperature rising of rings runway.If after the broken yarn, the speed of steel traveler on runway will reduce greatly, and at this moment the temperature of rings runway will reduce, and we can know that yarn is disconnected when temperature reduces.Adopt this detection mode, because the drop in temperature of rings runway is slower, sensor need to just can detect after broken yarn a period of time (being generally 8 to 16 seconds), sends the broken yarn signal so still can not in time find the ingot position of Yarn break.
Summary of the invention
The present invention is directed to deficiency of the prior art, a kind of broken yarn testing agency that can in time detect the ingot position of Yarn break is provided.
For solving the problems of the technologies described above, the present invention is solved by following technical proposals: broken yarn testing agency, comprise rings and steel traveler, the top of described rings is provided with the edge of a circle projection, described steel traveler is slidingly connected on the described edge, also comprise a photoelectric sensor, described photoelectric sensor comprises an emitting head and a Receiver, described emitting head is towards described edge-emission light, when the described echo area of described steel traveler process, the light that described emitting head sends is received by described Receiver through after the reflection of described steel traveler.When fine spining machine used, steel traveler High Rotation Speed, steel traveler whenever revolved and turn around, and will be launched a fixing position light that hair goes out and shine once, and we are referred to as the echo area to this position.The light that emitting head sends shines on the Receiver after reflecting through steel traveler, and Receiver just can receive signal.When steel traveler during in other positions, the light that emitting head sends can't reflex on the Receiver, and Receiver does not just have signal.During normal operation, the signal frequency that Receiver receives is a definite value, and this definite value equals the steel traveler number of turns that turn each second on rings.If the yarn broken string, steel traveler loses the draw of yarn, and under the effect of frictional force, the movement velocity of steel traveler on rings slows down greatly, that is to say that the frequency of the signal that Receiver receives descends rapidly.When the signal frequency that receives when Receiver reduced, we just can judge yarn and have broken, and adopt this detection mode, can greatly shorten the detection time of Yarn break, are convenient to the timely wiring of workman.
In the technique scheme, concrete, described steel traveler has the steel ring of a breach, and described steel traveler snaps in the described edge by breach.
In the technique scheme, concrete, also comprise a ring rail, the bottom of described rings is fixed on the ring rail, and described emitting head and described Receiver are fixed on the described ring rail.
In the technique scheme, concrete, also comprise spindle, described spindle passes described ring rail and described rings inner ring, is wound with yarn on the described spindle, and described yarn passes described steel traveler.
The invention has the beneficial effects as follows: when the signal frequency that receives when Receiver reduces, we just can draw yarn and break, adopt this detection mode, can greatly shorten the detection time of Yarn break, generally after yarn broken string, just can detect with interior in 1 second, be convenient to the timely wiring of workman.
