The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

A coil end face coil shape detection system according to the present invention will be described in detail with reference to the accompanying drawings.

As shown in fig. 1 and fig. 2, according to the utility model discloses a coil end face coil shape detecting system, include: a first ranging sensor 210, a second ranging sensor 220, and a server 300.

Specifically, the first ranging sensor 210 and the second ranging sensor 220 are disposed bilaterally symmetrically, wherein the first ranging sensor 210 is movable up and down and the second ranging sensor 220 is movable up and down.

In a specific application scenario, the first distance measuring sensor 210 and the second distance measuring sensor 220 are symmetrically arranged at the left and right sides of the steel coil transportation chain 100. The steel coil conveying chain 100 is provided with a plurality of

steel coil saddles

110, 120 arranged at intervals. It is understood that the

In operation, the first distance measuring sensor 210 and the second distance measuring sensor 220 move up and down according to the outer diameter of the steel coil 700, so that the measuring points of the first distance measuring sensor 210 and the second distance measuring sensor 220 are as high as the horizontal axis 710 of the steel coil 700. As the steel coil transportation chain 100 moves, the first and second ranging

sensors

210 and 220 continuously measure distance data of the end surface of the steel coil 700 and transmit the data to the server 300.

According to the utility model discloses an example, a coil of strip terminal surface roll form detecting system still including being used for the drive first linear drive device that first range sensor reciprocated, be used for the drive second linear drive device that second range sensor reciprocated and respectively with first linear drive device with switch board 500 that second linear drive device links to each other. Advantageously, the first linear drive device comprises: a first guide bar 411 and a first screw 412 respectively connected to the first distance measuring sensor 210, and a first motor 413 connected to the first screw 412 to drive the first screw 412 to rotate, the second linear driving device comprising: a second guide bar 421 and a second screw 422 respectively connected to the second distance measuring sensor 220, and a second motor 423 connected to the second screw 422 to drive the second screw 422 to rotate, wherein the first motor 413 and the second motor 423 are respectively connected to the control cabinet 500. That is, the control cabinet 500 may rotate the first motor 413 and the second motor 423 according to the outer diameter of the steel coil 700 to respectively drive the first screw 412 and the second screw 422 to rotate, and then respectively move the first distance measuring sensor 210 and the second distance measuring sensor 220 up and down to align the first distance measuring sensor 210 and the second distance measuring sensor 220 with the horizontal axis 710 of the steel coil 700.

According to a specific example of the utility model, a coil of strip terminal surface roll form detecting system still include first heat-insulating cabinet 610 and second heat-insulating cabinet 620, establish in the left and right sides of coil of strip transportation chain 100 first heat-insulating cabinet 610 and second heat-insulating cabinet 620 bilateral symmetry, first range sensor 210 with first linear drive device establishes in first heat-insulating cabinet 610, second range sensor 220 with second linear drive device establishes in second heat-insulating cabinet 620.

Therefore, the dust and heat can be protected, and the severe working condition of a workshop can be adapted.

Referring to fig. 1 to 3, assuming that the moving direction of the steel coil conveying chain 100 is from bottom to top, when the steel coil 700 to be detected reaches the front steel coil saddle 120, the PLC in the electric control cabinet 500 reads the outer diameter of the steel coil 700 from the PLC in the steel coil conveying chain 100. The electric control cabinet 500 then controls the first motor 413 and the second motor 423 to rotate so as to respectively drive the first screw 412 and the second screw 422 to rotate, and further respectively move the first distance measuring sensor 210 and the second distance measuring sensor 220 up and down so as to align the first distance measuring sensor 210 and the second distance measuring sensor 220 with the horizontal axis 710 of the steel coil 700. When the steel coil 700 moves from the position of the steel coil saddle 120 to the position of the steel coil saddle 110, the first distance measuring sensor 210 and the second distance measuring sensor 220 respectively and continuously measure the distance data of the two end surfaces of the steel coil 700. After the steel coil 700 reaches the position of the steel coil saddle 110, the measurement is completed. The whole measuring process is that the distance between each layer of strip steel and the corresponding distance measuring sensor is measured along a horizontal line 710 passing through the center of a circle on the steel coil 700 to be measured. A similar curve as shown in fig. 3 can be obtained after the measurement is completed.

This curve can be divided into 5 sections. In the first section 701, where the steel coil 700 has not yet entered the measuring point of the distance measuring sensor, all the measured values in this section are invalid values, which are typically a default value, for example 200. And a second section 702, in which the left half of the steel coil 700 enters a measurement point, wherein the measurement value of the second section indicates the height and undulation state of each layer of strip steel in the left half of the steel coil 700. In the third section 703, the measuring point of the distance measuring sensor is located in the inner circle of the steel coil, and the measured values are all invalid values. And a fourth section 704, in which the right half of the steel coil 700 enters a measurement point, and the measurement value of the section indicates the height and undulation state of each layer of strip steel in the right half of the steel coil 700. In the fifth section 705, where the coil 700 has been removed from the measurement point, the measurement is invalid.

Dedicated detection software running on the server 300 receives the ranging values sent from the two ranging sensors. And after eliminating singular values which do not accord with the rules, calculating the average value of all the distance measuring points to obtain the reference position of the end surface of the steel coil. And then calculating the difference between all the measuring points and the reference position to obtain a difference curve. Various types of roll defects can be judged on the difference curve according to the following principle:

and a raised point exceeding a set threshold exists near the outer ring of the steel coil, so that the existence of an overflow edge can be judged.

And a raised point exceeding a set threshold exists near the inner ring of the steel coil, so that the tower type can be judged to exist.

In the middle part of the steel coil, a convex point with a set threshold value is found, and the existence of a wrong layer can be judged.

In the whole measuring range, a plurality of continuous invalid value points which exceed the measuring range of the distance measuring sensor exist, and the side can judge that the roll loosening exists.

It should be noted that: and (3) calculating the distance measurement curve, only considering the convex points higher than the reference surface of the steel coil, and not considering the concave points lower than the reference surface. Because the concave points may be the concave parts of the strip steel or the gaps of the measuring points in the two layers of strip steel, the judgment by the concave points is inaccurate. The strip steel which is concave on one end face is inevitably convex on the other end face. Because the utility model discloses contain two range sensors that bilateral symmetry set up, detect two terminal surfaces of coil of strip respectively, consequently only consider the salient point and can not lead to lou examining.
