It is suitable for use in preventing dropping.
[0002]
[Prior art]
Conventionally, in a winding device for a thin metal strip, a thread generated on the surface of the metal strip when the metal strip is wound is formed by overlapping the thin metal strip and the metal strip when winding the thin metal strip into a coil shape. Often occurs. For example, Patent Documents 1 and 2 disclose, for example, conventional techniques for preventing a thread generated as described above.
[0003]
In the above-mentioned Patent Document 1, the friction between the metal bands is reduced by applying a lubricant to the surface of the metal band to prevent the occurrence of surface flaws, but it cannot be applied to the metal band of an oil-free material. It was.
[0004]
Moreover, in the said patent document 2, the vibration sensor is installed in the bearing part of the reel shaft of a coil winding apparatus, The vibration and displacement in a bearing part are detected, and generation | occurrence | production of a metal strip surface slip is prevented. However, in this case, since the vibration of the bearing portion of the reel shaft disposed in the coil winding device is detected, the actual behavior and vibration of the metal band cannot be directly detected, so the initial generation of the sleeve flaws. There is a problem that detection at a stage is difficult and detection accuracy is poor.
[0005]
As a conventional technique for predicting a thread generated on the surface of the thin metal strip, for example, Patent Document 3 proposes a “prediction method for occurrence of crack defects on the surface of a metal strip”. The prediction method proposed in Patent Document 3 detects the position in the plate width direction of the end of the metal strip inserted into the winding device for the metal strip in the rolling line, and the winding device from the position detection signal. A frequency component that matches the rotational frequency of the metal band is extracted, and the occurrence of scum on the surface of the metal band is predicted based on the signal level of the frequency component.

[Problems to be solved by the invention]
In the case of the “preliminary method for predicting occurrence of flaws on the surface of a metal strip” proposed in Patent Document 3 above, the diameter of the metal strip winding shaft is extracted using an eddy current sensor and matches the rotational frequency of the winding device. The frequency component to be detected was detected.
[0008]
In the case of the above eddy current sensor, the coil diameter is measured by detecting the eddy current generated in the inspection object. Therefore, if the eddy current does not flow, the coil diameter cannot be detected. The shaft diameter could not be measured with the rubber sleeve inserted into the shaft, and the roundness of the metal strip winding shaft could not be accurately measured with the rubber sleeve inserted. .
[0009]
The present invention has been made in order to solve the above-described problems, and a first object thereof is to detect the deflection amount of the metal strip winding shaft with high accuracy.
In addition, the roundness of the take-up shaft of the metal band can be detected with the rubber sleeve inserted so that the roundness of the take-up shaft before winding the metal band can be adjusted with high accuracy. The purpose of 2.
It is a third object of the present invention to make it possible to adjust the roundness of the take-up shaft with high accuracy through the inner sleeve inserted into the rubber sleeve.

DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of a sheet metal strip winding device, a sheet metal strip winding method, a computer program, and a computer-readable recording medium according to the present invention will be described with reference to the accompanying drawings.
[0015]
FIG. 1 is a block diagram showing an embodiment of a winding device for a thin metal strip according to the present invention. As shown in FIG. 1, the winding device of the thin metal strip of the present embodiment includes a first laser sensor 11, a second laser sensor 12, a reel rotation detector 13, a pulse generator 14, an arithmetic device 15, A coil outer shape display device 16, an alarm output device 17, a roundness adjusting means 18, and the like are included.
[0016]
The first laser sensor 11 is provided to detect the diameter on the drive side 2 side of the winding shaft 1 for winding the strip to generate the coil 5. The second laser sensor 12 is provided for detecting the diameter of the winding shaft 1 on the work side 3 side.
[0017]
The reel rotation detector 13 detects the rotation state of the winding shaft 1 and outputs a rotation detection signal to the pulse generator 14. Based on the rotation detection signal sent from the reel rotation detector 13, the pulse generator 14 outputs a pulse signal to the arithmetic unit 15 every time the winding shaft 1 makes one rotation.
[0018]
  The arithmetic device 15 is based on the diameter information of the drive side 2 of the winding shaft 1 input from the first laser sensor 11 and the diameter information of the work side 3 input from the second laser sensor 12. The difference between the diameter on the drive side 2 side and the diameter on the work side 3 side of the winding shaft 1 is calculated for each rotation of the winding shaft 1. Then, it is determined whether or not the calculation result is larger than a preset reference value X, and the determination result is output to the coil outline display device 16, the alarm output device 17 and the roundness adjusting means 18.Therefore, in this embodiment, the arithmetic unit 15 functions as roundness detection means.
[0019]
Here, the types of coil shake and the shake image will be described with reference to FIG. The coil runout that occurs when the metal strip is wound around the take-up shaft 1 can be broadly classified into vertical runout as shown in FIG. 9A and runout shown in FIG. 9B. .
[0020]
In the vertical deflection shown in FIG. 9A, the metal band surface to be wound and the coil surface are parallel to each other, and no relative deviation occurs. Therefore, in the case of vertical runout, no coil slip wrinkles that cause quality defects occur.
[0021]
On the other hand, in the case of the swing of FIG. 9B, a relative shift occurs between the metal band surface and the coil surface, and therefore, a coil slip defect that becomes a quality defect occurs. For this reason, slip wrinkles occur when the phase component of the whirling vibration at both end portions (drive side and work side diameters) of the winding surface is 180 °. This antiphase component is the same as the period of one rotation of the winding shaft 1.
[0022]
That is, slip wrinkles are not generated only in the lateral direction (thrust direction), and as shown by the arrows in FIG. 9B, coil slip wrinkles are generated when the entire coil is swung with waviness. Therefore, in the present embodiment, the occurrence of coil slip wrinkles is predicted by calculating the amount of deflection of both end portions 2 and 3 of the coil in synchronization with the rotation period of the winding coil.
[0023]
2 and 3 show a schematic configuration of a strip coil production line in which the sheet metal band winding device of the present embodiment is arranged, FIG. 2 is a configuration diagram seen from the side, and FIG. It is the block diagram seen from the upper direction.
[0024]
As shown in FIGS. 2 and 3, this strip coil production line includes a position control actuator 21, a vibration generator 23, an EPC (Edge Position Control) device 24, an automatic cutting device for controlling the position of the roll 22 in front of the reel. Machine 25 and the like.
[0025]
Next, the operation of the sheet metal band winding device of the present embodiment will be described with reference to the flowchart of FIG.
The thin metal strip winding device according to the present embodiment starts the operation after the rubber sleeve 4 is inserted into the winding shaft 1 in the first step S41, and the rubber sleeve 4 is inserted. The diameter of the winding shaft 1 is detected for each of the drive side 2 side and the work side 3 side. This detection is performed using the first laser sensor 11 and the second laser sensor 12, and in this embodiment, the detection is performed in a non-contact manner using the laser sensor. The diameter of the winding shaft 1 can be accurately performed in a state where the rubber sleeve 4 is inserted. Therefore, in the present embodiment, it is possible to accurately detect the roundness of the metal strip winding shaft 1 before starting to wind the thin metal strip.
[0026]
When the roundness is detected in a state where the rubber sleeve 4 is inserted in the metal strip winding shaft 1, it is desirable that the deflection amount is within about 1.0 mm when the sleeve diameter is about 500 mm. Therefore, it is desirable to adjust the roundness tolerance before starting to wind the coil to be within about “0.2%”.
[0027]
As a case where the roundness is not within the allowable amount, there are a case where the rubber sleeve 4 itself is not a perfect circle and a case where the mandrel segment is not expanded to a predetermined position.
[0028]
As described above, in the present embodiment, the roundness for adjusting the roundness by expanding the segment position of the mandrel to a predetermined position based on the roundness of the rubber sleeve 4 detected by the arithmetic device 15. Adjustment means 18 is provided.
[0029]
In the example shown in FIG. 1, the example in which the roundness of the rubber sleeve 4 is detected by the first laser sensor 11 and the second laser sensor 12 is shown. If the third laser sensor that mainly detects the amount of vibration is provided, the profile of the rubber sleeve 4 can be detected more clearly.
[0030]
As described above, when the roundness is not obtained even when the mandrel segment position is enlarged to a predetermined position and the roundness is adjusted, the roundness of the rubber sleeve 4 itself is predetermined. In this case, the rubber sleeve 4 is replaced so that a predetermined roundness can be obtained.
[0031]
In the description of the roundness adjustment described above, the “wrapper roll type winding device” is shown to explain the procedure for adjusting the roundness. However, after the rolling line, the “belt wrapper type” as shown in FIG. The winding device "is used. In FIG. 11, reference numeral 111 denotes a belt wrapper belt that wraps the thin metal strip 110 around the mandrel MD.
[0032]
Practical displacement meters can be broadly classified into non-contact displacement meters and contact displacement meters.
As the non-contact type displacement meter, an eddy current type, an optical type and an ultrasonic type are known. An inductance displacement meter is known as a contact displacement meter.
[0033]
Since the measurement principle of the eddy current displacement meter uses an impedance change caused by a magnetic field, the object to be measured is limited to metal. The spot property on the measurement surface is moderate, which is inferior to the optical type and the contact type, but better than the ultrasonic type. Although it is excellent in terms of accuracy, it has a drawback of being weak against curved surfaces. The resolution is about 0.3 μ to 1 μ, the measurement range is 0 to 10 mm, and the response frequency is about 18 kHz at the maximum.
[0034]
Since the measurement principle of the optical displacement meter uses a semiconductor laser, the measurement object can be used for both solid and liquid. Moreover, it is excellent in the spot property with respect to a measurement surface regardless of transparent / opaque. Furthermore, the accuracy is excellent, the resolution is about 0.01 μ to 0.2 μ, the measurement range is 9 to 750 mm, and the response frequency is about 3 to 20 kHz at the maximum.
[0035]
The measurement principle of the ultrasonic displacement meter is based on the reflected time of the emitted sound wave, so the measurement object can be used for both solid and liquid, and transparent / opaque It doesn't matter. However, the spot property on the measurement surface is low and inferior to the optical type and the contact type. Also, the accuracy is inferior, and there is a drawback that it is affected by the ambient temperature. The resolution is about 100 μm, the measurement range is 60 to several tens mm, and the response frequency is about 20 kHz at the maximum.
[0036]
Since the measurement principle of the contact displacement meter uses an inductance change, the measurement object is limited to a solid. It is excellent with respect to the spot property and accuracy with respect to the measurement surface. The resolution is 0.16 μ, the measurement range is 1 to 10 mm, and the response frequency is about 40 kHz at the maximum.
[0037]
In this embodiment, since the displacement is measured in a low cycle (up to about 10 kHz), measurement can be performed using any sensor, but fluctuations between the material of the measurement object and the measurement distance, and fluctuations in locality Measure the whirling of the coil using a “laser displacement meter” that has high-precision (resolution of about 0.01 mm or more), non-contact and long-distance measurement. I am doing so.
[0038]
After the rubber sleeve 4 is inserted into the metal strip winding shaft 1, the process proceeds to step S42, and the roundness is detected. This detection is performed by measuring the diameters on the drive side 2 side and the work side 3 side of the metal band winding shaft 1 using the first laser sensor 11 and the second laser sensor 12 described above, The diameter information of the metal strip winding shaft 1 detected by the first laser sensor 11 and the second laser sensor 12 is sent to the arithmetic unit 15.
[0039]
A pulse signal is input from the pulse generator 14 to the calculation device 15, and the amount of swing is calculated each time the metal strip winding shaft 1 makes one rotation. This calculation is performed when the diameter on the drive side 2 output from the first laser sensor 11 is A and the diameter on the work side 3 output from the second laser sensor 12 is B. AB)_PPIt is performed based on whether or not the expression of “≧ reference value X” is satisfied.
[0040]
As a result of the calculation performed in step S42, it is determined in step S43 whether or not the swing amount of the metal strip winding shaft 1 is larger than the reference value X. If the result of this determination is that the amount of swing of the metal strip take-up shaft 1 is greater than the reference value X, the process proceeds to step S44, where an alarm signal is output from the arithmetic unit 15 to the alarm output unit 17 and the coil outline display is displayed. The coil outer diameter is displayed on the device 16. When the warning signal is input, the warning output device 17 notifies the operator that the swing amount of the metal strip winding shaft 1 has exceeded the reference value X by, for example, generating an alarm sound.
[0041]
Next, it progresses to step S45 and it is determined whether the runout amount of the metal strip winding shaft 1 is larger than the 1st threshold value a. This determination is made by “(A−B)_PP≧ a ”. If the result of this determination is that the amount of swing of the metal strip take-up shaft 1 is greater than the first threshold value a, the process proceeds to step S46, where the gain of the EPC device (not shown) is lowered to reduce the sensitivity. Adjust the direction.
[0042]
Then, it progresses to step S47 and it is determined whether the runout amount of the metal strip winding shaft 1 is larger than the second threshold value b. This determination is made by “(A−B)_PP≧ b ”. If the result of this determination is that the amount of swing of the metal strip take-up shaft 1 is greater than the second threshold value b, the routine proceeds to step S48, where the position control of the reel front roll 22 is performed.
[0043]
The position control of the reel front roll 22 generates an antiphase component signal for canceling the swinging of the metal strip winding shaft 1, and outputs the antiphase component signal to the position control actuator 21 to This is done by applying an antiphase component to the thin metal strip via the roll 22.
[0044]
Next, the process proceeds to step S49, and it is determined whether or not the swing amount of the metal strip winding shaft 1 is larger than the third threshold value c. This determination is made by “(A−B)_PP≧ c ”. If the result of this determination is that the amount of swing of the metal strip take-up shaft 1 is greater than the third threshold value c, the routine proceeds to step S50, where control is performed to automatically divide the coil.
[0045]
As described above, when the amount of swing of the metal strip winding shaft 1 becomes larger than the third threshold value c, the coil is automatically divided, so that a three Occurrence can be prevented. Thereby, it can prevent reliably that the thin metal strip | belt which a crack generate | occur | produced mixes in a coil.
[0046]
FIG. 5 (a) shows the displacement amount on the drive side 2 side and the displacement amount on the work side 3 side. FIG. 5 (b) shows the result of the FFT analysis of the displacement on the work side 3 side. The result of FFT analysis of the displacement on the side 2 side is shown.
[0047]
FIG. 6 shows how the FET reading changes depending on the presence or absence of swinging. 5 and 6, f0 indicates that the metal strip winding shaft 1 makes one rotation (360 °), 2f0 indicates that the metal strip winding shaft 1 makes 1/2 rotation (180 °), and 3f0 indicates a metal. The band winding shaft 1 shows 1/3 rotation (120 °), 4f0 shows the metal band winding shaft 1 1/4 rotation (90 °), and 5f0 shows the metal band winding shaft 1 1/5 rotation. (72 °).
[0048]
As can be seen from these figures, as the difference between the diameter on the work side 3 side and the diameter on the drive side 2 side increases, the amount of swirling of the metal strip winding shaft 1 increases. Therefore, as described above, the winding device for the thin metal strip of the present embodiment detects that the amount of swinging of the metal strip winding shaft 1 has increased, and predicts the occurrence of scratches. ing. Further, at the time when the occurrence of the sleeve is predicted, the vibration of the coil is suppressed by applying an antiphase vibration to the reel roll 22 and canceling the phase difference.
[0049]
Further, when the amount of swing of the metal strip winding shaft 1 becomes large and the phase difference cannot be canceled even if the position control of the reel front roll 22 is performed, the automatic cutting machine 25 is controlled to operate the coil. By automatically cutting, it is possible to prevent the generation of a sleeve and to prevent the thin metal strip having the sleeve from entering the coil.
[0050]
(Example)
Next, an embodiment in which a coil is manufactured using the thin metal strip winding device of the present invention will be described with reference to FIGS.
FIG. 7A shows an example in which a coil having an outer diameter of 600 mm, 1100 mm, and 1400 mm is manufactured by winding a thin metal strip having a thickness of 0.2 mm and a width of 880 mm. In this case, when the outer diameter was 600 mm and 1100 mm, the speed of the metal strip winding shaft 1 was 750 mpm, and when the outer diameter was 1400 mm, the speed of the metal strip winding shaft 1 was 650 mpm. In the case of this example, a difference between the diameter on the work side 3 side and the diameter on the drive side 2 side was not recognized, and no crack was generated.
[0051]
In FIG. 7B, a thin metal strip having a thickness of 0.28 mm is wound to manufacture a coil having an outer diameter of 600 mm and 1100 mm, and a thin metal strip having a thickness of 0.20 mm and a width of 766 mm is wound to 1400 mm. The example which manufactured this coil is shown. In this case, when the outer diameter of the coil is 600 mm, the difference between the diameter on the work side 3 side and the diameter on the drive side 2 side is 1.1 mm, the outer diameter of the coil is 1100 mm, and the outer diameter of the coil is 1400 mm. In this case, the difference between the diameter on the work side 3 side and the diameter on the drive side 2 side was 1.3 mm. In either case, the amount of swirling was small, so no thread was generated in this case.
[0052]
FIG. 7C shows an example in which a thin metal strip having a plate thickness of 0.32 mm and a plate width of 790 mm is wound to produce coils having outer diameters of 600 mm, 1100 mm, and 1400 mm. In this case, when the coil outer diameter is 600 mm, the difference between the diameter on the work side 3 side and the diameter on the drive side 2 side is 0.9 mm, and when the coil outer diameter is 1100 mm, the diameter on the work side 3 side. When the coil outer diameter is 1400 mm, the difference between the work side 3 side diameter and the drive side 2 side diameter is 2.2 mm. Therefore, in this case, the amount of run-out is small in the case of a coil having a coil outer diameter of 600 mm, and thus no generation of scratches occurred. So there was a pickpocket.
[0053]
FIG. 7D shows an example in which a thin metal strip having a plate thickness of 0.35 mm and a plate width of 819 mm is wound to manufacture coils having outer diameters of 600 mm, 990 mm, and 1200 mm. In this case, when the coil outer diameter is 600 mm, the difference between the diameter on the work side 3 side and the diameter on the drive side 2 side is 1.0 mm, and when the coil outer diameter is 990 mm, the diameter on the work side 3 side is When the coil outer diameter is 1200 mm, the difference between the work side 3 side diameter and the drive side 2 side diameter is 2.8 mm. Also in this case, the amount of run-out was small in the case of a coil having an outer diameter of 600 mm, and thus no crack occurred. However, the amount of run-out was large in the case of a coil having an outer diameter of 850 mm and a coil having a diameter of 1200 mm. So there was a pickpocket.
[0054]
FIG. 8 shows an example of the measurement result of the reel outer diameter profile. In the example shown in FIG. 8A, the outer diameter hardly changes on both the work side 3 side and the drive side 2 side during one rotation of the metal band winding shaft 1 (tension reel), and the mandrel (metal band) The outer diameter of the winding shaft is flat and roundness is ensured.
[0055]
In FIG. 8B, there is a change in the outer diameter of about 1.13 mm at the center of the rubber sleeve. Moreover, in the segment part, the recess of the sub-segment is about 1.0 mm, and it can be seen that the outer diameter of the rubber sleeve is deformed at the same position as the segment of the mandrel.
[0056]
In the above-described embodiment, if the result of determination in step S47 of FIG. 4 is that the amount of swing of the metal strip winding shaft 1 is greater than the second threshold value b, the position of the reel front roll 22 is determined in step S48. An example of performing control is shown. However, instead of performing the position control of the reel front roll 22, the vibration generator 23 is operated so as to reverse the change in the shape of the thin metal strip by applying an antiphase vibration to the thin metal strip, You may make it suppress the generation | occurrence | production of a crack by making the amount of whirlings of the metal strip winding shaft 1 small.
[0057]
The vibration generator 23 can be configured using, for example, a wiping device. In this case, the anti-phase vibration is applied to the thin metal strip by blowing air.
[0058]
The embodiment described above has shown an example in which the coil 5 is manufactured by directly winding a thin metal strip on the rubber sleeve 4. However, as shown in FIGS. 12A to 12E, the coil 5 is manufactured by inserting the inner sleeve 4a on the rubber sleeve 4 and winding a thin metal strip on the inner sleeve 4a. Yes.
[0059]
The inner diameter sleeve 4a is formed of iron, aluminum, paper, or the like, and is removed from the rubber sleeve 4 together with the coil 5 after the thin metal strip has been wound.
[0060]
When the inner diameter sleeve 4a is used as described above, (a) the roundness of the rubber sleeve 4 is measured → (b) If the predetermined roundness cannot be obtained as a result of this measurement, the mandrel is opened. If the degree of roundness cannot be obtained even after the adjustment, the rubber sleeve 4 is replaced.
[0061]
Next, (d) the inner sleeve 4a is inserted on the rubber sleeve 4, and the roundness of the inner sleeve 4a is measured. → (e) If the predetermined roundness is not obtained as a result of the above measurement, the inner diameter sleeve 4a is replaced.
[0062]
As described above, the roundness of the winding shaft is set within a predetermined range, and (f) the thin metal strip is started to be wound and the outer diameter of the coil 5 is detected to measure the deflection amount. Like that.

【The invention's effect】
As described above, according to the present invention, when a coil is manufactured by winding a thin metal strip that has been subjected to a predetermined treatment, the drive side of the winding shaft for winding the thin metal strip is wound. There is provided at least a first laser sensor for detecting a winding diameter and a second laser sensor for detecting a winding diameter on the work side of the winding shaft, and the amount of deflection on the drive side of the winding shaft and the workpiece Since the phase difference from the side deflection is detected, the roundness of the metal belt winding axis can be continuously and accurately measured from the beginning of winding to the end of winding. . As a result, the coil can always be wound in a state where the amount of run-out is small, and the generation of scratches can be prevented and the yield in coil manufacturing can be greatly improved.
[0071]
According to another aspect of the present invention, the roundness of the rubber sleeve inserted in the winding shaft for winding the thin metal strip is detected, and the roundness of the rubber sleeve is detected based on the detection result. Since the roundness is adjusted, it is possible to detect and adjust the roundness of the winding shaft immediately before starting winding the metal strip with high accuracy.
[0072]
According to another feature of the present invention, since the roundness of the winding shaft is detected via the inner diameter sleeve inserted in the rubber sleeve, the inner diameter sleeve is a defective product. Inconveniences caused by this can be prevented, and the coil can always be wound up with a small amount of swing.
[0073]
According to another feature of the invention, the phase difference between the drive-side shake amount and the work-side shake amount of the winding shaft detected by the roundness detecting means is calculated, and the calculation is performed. Since an alarm is output when the phase difference reaches a predetermined value, it is possible to take appropriate measures before the occurrence of a sleeve due to the swinging of the metal strip winding shaft. Yield reduction due to drought can be minimized.
[0074]
According to another feature of the present invention, the gain of the metal band edge position control device is adjusted when the phase difference calculated by the phase difference calculation means reaches a predetermined value. A thread generated due to an inappropriate gain of the edge position control device can be prevented.
[0075]
According to another feature of the present invention, when the phase difference calculated by the phase difference calculating means reaches a predetermined value, an antiphase vibration is applied to the thin metal strip to reduce the phase difference. Since it is made to decrease, it is possible to greatly suppress the scratches caused by the position of the roll before the reel and the shape of the thin metal strip.
[0076]
According to another feature of the present invention, when the phase difference calculated by the phase difference calculating means reaches a predetermined value, a metal band cutting device for cutting the thin metal band is operated. Since the coil is divided in the middle, it is possible to improve the yield by suppressing the generation of cracks due to thick winding of the coil, and greatly increase the possibility that the thin metal strip with the cracks mixed into the coil. Can be reduced.
