A kind of whole core belt mechanical splice on-line measuring device and method
Technical field
The invention belongs to the technical field of adhesive tape machinery tool joint monitor, be specifically related to a kind of whole core belt mechanical splice on-line measuring device and method.
Background technology
The kind of adhesive tape mechanical splice damage: button wear down, button drops, and button is integral inclined, and button tilts, and belt edge button is damaged, and edge bracelet is dehisced.
The reason of mechanical splice damage: 1, wearing and tearing, foreign matter wearing and tearing, in adhesive tape operational process, bracelet and cylinder, carrying roller constantly rub.Button is thinning, and mechanical strength reduction causes damaging, and finally causes button to come off.2, pulling force, bracelet connection is inaccurate, and operational process center tap place unbalance stress, causes tearing from joint two edges, and 3, sideslip, belt deviation causes belt and belt holder strong friction, the belt clamps wearing and tearing of string pin edge; 4, material impact, when loading material, material is pounded and is fallen to causing joint distortion, and mechanical strength dies down, and increases the weight of mechanical wear.
Existing method of inspection has: high-power x-ray fluoroscopy, and wide-angle is red outward takes pictures, magnetic detection, metal detection.High-power x-ray fluoroscopy, cost is high, needs upper and lower two complete equipments, has radiation.Wide-angle infrared photography, intuitively, but antifouling difficulty, image procossing difficulty is larger.
Summary of the invention
The present invention damages the problems referred to above of method of inspection existence in order to solve existing adhesive tape mechanical splice, provide a kind of whole core belt mechanical splice on-line measuring device and method.
The present invention adopts following technical scheme to realize:
Whole core belt mechanical splice on-line measuring device, it is characterized in that comprising the Sensor box arranged perpendicular to adhesive tape service direction, some sensors arranged along belt width direction are set in Sensor box, sensor arranges two row up and down at adhesive tape, each sensor covers 30 ~ 40mm, described sensor is magnetic detection sensor, the signal output part connection signal treater of sensor.
Whole core belt mechanical splice online test method, complete based on above-mentioned whole core belt mechanical splice on-line measuring device, described step is as follows:
1), adhesive tape serviceable condition runs first, and sensor gathers the standard signal of each mechanical splice,
2), in follow-up operation process, continue the contrast signal gathering each mechanical splice, contrast signal and standard signal contrast,
3), according to the operating needs of belt conveyer, the failure criteria of single mechanical splice is set,
4), in conjunction with failure criteria, with the percentage settings alarming value damaging mechanical splice number or damage number, contrast signal and standard signal contrast, reach alert if, signal processor is reported to the police,
5), in conjunction with failure criteria setting parking value, reach Parking condition, stop.
Tape inlet and the adhesive tape outlet of described adhesive tape storage cassette holder are respectively arranged with Sensor box.Described parking step is the contrast signal that the Sensor box collection machinery joint at tape inlet place reaches failure criteria, the Sensor box in adhesive tape exit gathers the contrast signal reaching mechanical splice failure criteria again, record the time difference between twice collection, by the running velocity of adhesive tape, calculate the length of tape in storage cassette holder, then calculate and damage mechanical splice to the distance of helpdesk, realize vehicle positioning stop.
Hinge structure of the present invention has following beneficial effect:
1, noncontact measurement, can not produce any damage for belt, thus improves the safety and reliability of system, judging nicety rate Kodak 98%.
2, can long-time stable work, can carry out continuously for a long time monitoring, analyzing and identification mission.
3, synchronously can detect when production run, contribute to shortening belt service intervals.
4, operating personal can facilitate the situation of each joint different time of comparison, and the change judgement comparing artificial butt junction can be more directly perceived.

Detailed description of the invention
By reference to the accompanying drawings the specific embodiment of the present invention is described further.
Whole core belt mechanical splice on-line measuring device, comprise the Sensor box arranged perpendicular to adhesive tape service direction, some sensors arranged along belt width direction are set in Sensor box, sensor arranges two row up and down at adhesive tape, each sensor covers 30 ~ 40mm, described sensor is magnetic detection sensor, and the signal output part of sensor connects CAN communication module, then connection signal treater.Tape inlet and the adhesive tape outlet of described adhesive tape storage cassette holder are respectively arranged with Sensor box.
Sensor box, for measuring the degree of impairment of adhesive tape pros and cons mechanical splice, has 40 sensors (for 1.2m adhesive tape) in each Sensor box, number of sensors increases with belt width and increases, and each sensor covers 1-2 mechanical splice.
Signal processor mainly comprises power module, high-speed microprocessor module and power supply servo module.
Power module: power supply needed for each module is mainly provided.
High-speed microprocessor module: mainly complete sensor data acquisition and process, and communication.
Power supply servo module: mainly according to the order of upper computer, open and power cutoff module.
Explosion-proof computer: the data receiving one-chip computer module transmission, carries out processing, shows, stores, generates examining report, Self-Check Report etc.
Whole core belt mechanical splice online test method, step is as follows:
1), adhesive tape serviceable condition runs first, and sensor gathers the standard signal of each mechanical splice, multi-form mechanical splice Criterion signal library.
2), in follow-up operation process, continue the contrast signal gathering each mechanical splice, contrast signal and standard signal contrast,
3), according to the operating needs of belt conveyer, set the failure criteria of single mechanical splice, such as wearing and tearing >=20%, cracking, dislocation more than 15% and deflection more than 10%, reach failure criteria, classify as problematic mechanical splice, those skilled in the art can according to the adhesive tape specifically detected and production status setting
4), in conjunction with failure criteria, with the percentage settings alarming value damaging mechanical splice number or damage number, those skilled in the art can according to the adhesive tape specifically detected and production status setting, such as, 5% mechanical splice on adhesive tape reaches failure criteria and points out, 10% mechanical splice reaches failure criteria and reports to the police, and 15% mechanical splice reaches failure criteria and has a power failure.Contrast signal and standard signal contrast, reach alert if, signal processor is reported to the police,
5), set parking value, those skilled in the art according to the adhesive tape specifically detected and production status setting, can reach Parking condition, stop.
Described parking step is: the Sensor box collection machinery joint at tape inlet place reaches the contrast signal of failure criteria, the Sensor box in adhesive tape exit gathers the contrast signal reaching mechanical splice failure criteria again, record the time difference between twice collection, by the running velocity of adhesive tape, calculate the length of tape in storage cassette holder, then calculate and damage mechanical splice to the distance of helpdesk, realize vehicle positioning stop.
