Abstract

The invention relates to an automatic online detection device for silk, yarn and wires during high speed rotating or twisting or operating, comprising a force sensor, a wire guiding wheel or a yarn guiding head, and yarn guiding wheels, wherein, the wire guiding wheel or the yarn guiding head is arranged on the detection end of the twisting shaft of the force sensor, and two sides of the yarn guiding head are provided with the yarn guiding wheels of the yarn inlet and the yarn outlet of a transmission device; the forced direction of the twisting shaft of the force sensor is parallel with or perpendicular to yarn moving direction; the invention has the advantages that the automatic online detection device for silk, yarn and wires can be matched with various tension sensors and can be conveniently and reliably used for online tension detection during high speed operation or twisting. When the automatic online detection device for silk, yarn and wires shuts down, a yarn supporting head can act under the actuation function of a tension spring and a magnetic induction loop under the condition of no wire breaking or continuous doffing during operating. The automatic online detection device for silk, yarn and wires can rapidly and effectively carry out zero setting to the sensor, and the indicator lights are simultaneously lightened during the zero setting so as to ensure the precision of online tension detection.

Description

Silk, yarn, line micro-tension online detection device

Technical field:

A kind of silk of patent of the present invention design, yarn, line tension automatic on-line pick-up unit, the device that concrete use detects dynamic permanent tension force in metal wire-drawing, optical fiber cable, electric wire, cable, chemical fibre, weaving, industry such as knitting.Stop not broken yarn or do not shut down under the situation of winder in running, the adhesive effect by extension spring, magnetic induction loop makes the action of holder loose thread, can fast and effeciently realize the zero-bit adjustment to sensor, thereby guarantee the precision of tension force online automatic detection.

Background technology:

200510024019.0 Chinese invention patent; 200710045540.1 Chinese invention patent application; 2007100455399 Chinese invention patent applications disclose the power sensing of multiple automatic detection device, and (see Fig. 5, Fig. 6 Fig. 7), is applicable to line, rope, bundle, stressed online detection tension pick-up in the motion of bar and sheet material.These sensing devices are being equipped with multi-form conducting parts, applicable to the tension force on-line automatic detection device of the detected material of difformity; But above several patents and patented claim be the form of A place, test side conducting parts openly, is particularly shutting down, do not break or non-stop-machine situation under, can not adjust the zero-bit of sensor, thereby influence the precision and the indicating value of tension force detection.

Adopt the high precision ccd sensor in the market, at random the tension in the roving state is detected.Ultimate principle is to utilize ccd sensor that three kinds of states of rove are carried out detection of dynamic, as shown in Figure 3: since in dynamically producing rove in high speed rotating, twisting, the vibration that adds plant equipment has caused rove beating heart up and down moving, thereby can't detect the on-line tension and the tension force deviation of rove at all, have a strong impact on the effect that on-line tension detects.

A kind of high speed, fine-tension force rove testing apparatus have been announced in 2008100406876 Chinese invention patent applications; this device can be adjusted transducer zeroing by the interaction energy of magnet and magnetic induction loop under the situation of broken yarn not when shutting down; this device has been because the existence of magnet has seriously disturbed magneto-dependent sensor to detect dynamically, thereby influenced the precision of on-line tension and detected effect.

Summary of the invention:

The structure of patent of the present invention comprises the sensor or the other forms of force transducer part of above multinomial patented claim, an intrinsic guide head is located in the test side that it is characterized in that the force transducer torsion shaft, one side of guide head links to each other with yarn entering opening, and another side links to each other with yarn outlet.Torsion shaft be subjected to force direction consistent with the traffic direction of yarn, also can be vertical mutually with the traffic direction of yarn.

Advantage of the present invention is to cooperate with multiple force transducer; be applicable to the online automatic detection of silk, yarn, line tension easily and reliably; and can be on-stream do not shut down doff or shut down under the situation of broken yarn not; by extension spring, magnetic induction loop, computing machine sensor is carried out the zero-bit adjustment; pilot lamp is lighted simultaneously during zeroing, thereby has guaranteed the tension force accuracy of detection.
