Technical field
The utility model relates to a kind of optical fiber type fine spining machine yarn broken ends inspector, belongs to textile machine ring throstle Yarn break detection technique field.
Background technology
In the yarn process processed of fine spining machine, rove is entered to drafter from hanging to split delivering to guided missile reed horn mouth, by the pneumatic apparatus for collecting in drafter in centralizing pipe under negative-pressure air-flow effect, when making fiber strip filoplume along with grid ring rotational conveyance, on air-flow guide groove, gathered, reach the powerful requirement that reduces sliver filoplume and increase yarn, sliver after gathering enters steel traveler by twizzle and twists, and will on the reel for yarn winding reel after twisting, be shaped.
In the twisting process of spun yarn, the yarn of the front roller output of drafter is through being arranged on the twizzle on thread board, again through being arranged on the steel traveler on rings, in the rotation process of stator by yarn around to being tightly placed on the bobbin of spindle, during spindle revolution, by affecting of yarn tension, steel traveler is turned round along rings, steel traveler drives yarn to return yarn while going around along rings and just obtains a turn, and be arranged on ring rail rings as the rotating track of steel traveler, in twisting process yarn in tow steel traveler on rings, make high speed rotary, effect at centrifugal force, the inner arc that makes the interior pin of steel traveler be close to rings is to slide on inner track, conventionally the speed of gyration of steel traveler on rings runway can reach 30m/s～50m/s left and right, and after the Yarn break of one of them position of splitting, this steel traveler that splits position can not normally turn round.
Yarn break for Yarn twisting one side detects at present, adopt touring mobile detection mode, in ring rail front side, to establish a runway is installed, magnetoelectric transducer is arranged on runway, by mobile magnetoelectric transducer, induce the turn signal of a steel traveler that respectively splits, and by wire by signal in central processing unit, to detect each ingot position breakage situation.But owing to needing runway to be arranged on the front portion of ring rail, and runway drives inconvenience for operation and cleaning, and especially magnetoelectric transducer detects the steel traveler of each ingot position by patrolling and examining, therefore can not find in time the ingot position of Yarn break and send signal.
Summary of the invention
The purpose of this utility model is to provide a kind of rational in infrastructure, easy for installation, detects accurately, and detection reaction is rapid, disturbs to external world little fine formula fine spining machine yarn broken ends inspector.
The utility model is that the technical scheme achieving the above object is: a kind of optical fiber type fine spining machine yarn broken ends inspector, comprise a plurality of rings that are arranged on ring rail and be arranged on the steel traveler on each rings runway, it is characterized in that: the Fibre Optical Sensor corresponding to each rings is installed on described ring rail, comprise that the Fibre Optical Sensor of the first optical fiber and the second optical fiber is positioned at the outer peripheral face of rings runway, the Fibre Optical Sensor signal processor of Fibre Optical Sensor is connected with treatment circuit.
Wherein: on described ring rail, connector is installed, and the first optical fiber and the second optical fiber is arranged on ring rail by connector, the end of the first optical fiber and the second optical fiber is facing to the bottom of rings.
Described treatment circuit is voltage comparator.
The utility model is provided with the Fibre Optical Sensor corresponding to each rings on the ring rail of fine spining machine, this Fibre Optical Sensor comprises that the first optical fiber and the second optical fiber form, because Fibre Optical Sensor is arranged on steel neighbour outside, therefore the outer peripheral face of rings runway can be used as reflecting surface, the first optical fiber of Fibre Optical Sensor is to rings emission of light, and the second optical fiber receives by rings surface reflection light, light intensity when Fibre Optical Sensor detects steel traveler revolution changes, because spindle is to drive yarn bobbin to rotate by certain speed, and drive steel traveler to turn round by certain speed by yarn, make Fibre Optical Sensor the revolution variable signal of steel traveler can be detected, only have the yarn of working as to have no progeny, because steel traveler can not be by existing speed revolution and until stop revolution, therefore Fibre Optical Sensor can be able to detect rapidly steel traveler revolution variable signal, each self-corresponding steel traveler revolution variable signal of collection is inputed to treatment circuit after Fibre Optical Sensor signal processor processes, treated processing of circuit offers CPU, can accurately obtain Yarn break signal.When the steel traveler revolution variable signal after the judgement of the utility model CPU is processed is not continuous impulse signal, export broken yarn signal and pass through alarm equipment alarm, detect timely and effectively the broken yarn situation of each ingot position yarn, effectively raise wiring workman's operating efficiency, the waste of the yarn of minimizing.The utility model is arranged on Fibre Optical Sensor on the ring rail of fine spining machine, rational in infrastructure, compact, easy for installation, can not affect normal operating, detect fast response time, disturb to external world little, can effectively improve the detection accuracy of Yarn break, adopt and have or not movable electrical contact to detect, reliable operation, long service life.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Fig. 1 is the structural representation of a kind of optical fiber type fine spining machine of the utility model yarn broken ends inspector.
Fig. 2 is the electrical schematic diagram of the utility model treatment circuit.
Wherein: 1 one treatment circuits, 2 a connection piece, 3 one Fibre Optical Sensors, 3-1 mono-first optical fiber, 3-2 mono-second optical fiber, 4 one steel travelers, 5 one yarns, 6 one yarn bobbins, 7 one rings, 8 one ring rails.
The specific embodiment
See Fig. 1, shown in 2, a kind of optical fiber type fine spining machine yarn broken ends inspector of the present utility model, comprise a plurality of rings 7 that are arranged on ring rail 8 and be arranged on the steel traveler 4 on each rings runway, from the yarn 5 of drafter front roller output, after the twizzle being arranged on thread board, pass the steel traveler 4 on rings 7, around to being tightly placed on the yarn bobbin 6 of spindle, while driving yarn bobbin 6 revolution by spindle, by affecting of yarn tension, make steel traveler 4 along rings runway upper rotary, the turn that steel traveler 4 revolutions produce is to front roller nip transmission, the yarn at jaw place is turned round around axis, yarn width shrinks gradually, both sides are also folding and be involved in and in sliver, be formed centrally twist triangle zone gradually, in twist triangle zone, width and the cross section of yarn change, and twist.
