Referring to fig. 1, fig. 1 is a schematic overall flow chart of a roll diameter measurement method for adaptively eliminating an installation error according to an embodiment of the present application.
As shown in fig. 1, the method for measuring the coil diameter capable of adaptively eliminating the installation error at least comprises the following steps:
step 102, determining a radius of the measured object in an unreeled state and a first measurement distance between the measured object and the measurement sensor.
The method for measuring the winding diameter in the embodiment of the application and capable of adaptively eliminating the installation error can be applied to a winding mechanism of a coater, a winding machine, a roller press, a printer and the like, and the winding mechanism of the coater, the winding machine, the roller press, the printer and the like can comprise a measured shaft for winding, a laser sensor or an ultrasonic sensor, a sensor mounting bracket and a signal processing module. The sensor mounting bracket can be used for supporting and fixing the laser sensor or the ultrasonic sensor, and the signal processing module can be used for obtaining the winding diameter of the measured shaft according to the distance acquired by the laser sensor or the ultrasonic sensor.
In the conventional winding diameter measuring technology, the sensor mounting bracket is generally used to fix the position of the laser sensor or the ultrasonic sensor when the measured object is in an unreeled state, but the present invention is not limited to the method, so that the axis of the laser sensor or the ultrasonic sensor coincides with the axis of the measured object, and the actual calibration distance between the transmitting port of the laser sensor or the ultrasonic sensor and the axis of the measured object can be recorded. Then, after the measured object completes the rolling action, the laser sensor or the ultrasonic sensor can collect the actual measurement distance from the transmitting port to the current measured object, and the actual radius of the measured object can be obtained by the following formula:
actual radius = actual calibration distance-actual measurement distance
Reference may also be made herein to fig. 2 for a schematic diagram illustrating the effect of an existing roll diameter measurement method according to an embodiment of the present application. As shown in fig. 2, when the measured object is in an unreeled state, an actual calibration distance between the transmitting port of the ultrasonic sensor and the axis of the measured object may be determined, but not limited to, as follows:
actual calibration distance = hollow shaft radius + board card measured value + sensing blind area value
Board measured value= (sensor measuring range maximum value-sensor blind zone value) analog distance/analog resolution
After the measured object completes the rolling action, the ultrasonic sensor can acquire the actual measured distance from the transmitting port to the current measured object, and the determination method can be but is not limited to the following steps:
actual measurement distance = board card measurement average value + sensing blind area value
Board card measuring average value = (sensor measuring range maximum value-sensor blind zone value) analog average distance/analog resolution
Then, the actual radius of the measured object can be obtained by the following formula:
actual radius = actual calibration distance-actual measurement distance
Here, the actual calibration distance may also be, but not limited to, obtained by actual measurement by a worker, and the actual measurement distance may be directly determined by data collected by the ultrasonic sensor, which is not limited in the embodiment of the present application.
It can be understood that the production, processing and installation of actual equipment all can lead to sensor installation to have certain error, and along with the accumulation of machine running time and vibration of equipment itself, the mounted position that can lead to the sensor produces the deviation with the design position simultaneously, influences the actual measurement of roll diameter, causes fluctuation or the accumulated error of measuring result, influences the measurement of coiled material on the one hand, influences the control effect of tapering tension on the other hand, leads to the fault such as rolling terminal surface uniformity is poor, film roll surface longitudinal stripe, barrel-shaped rolling, coiled material stretch-break.
Specifically, when the winding mechanism of the coating machine, the winding machine, the roller press, the printing machine and other equipment is subjected to winding diameter measurement, the radius of the measured object in an unreeled state is determined, and under the condition that the axis of the measuring sensor is fixed by the sensor mounting bracket and the axis of the measured object coincides, the first measuring distance between the measured object and the measuring sensor is determined. The measuring sensor may be, but not limited to, an ultrasonic sensor or a laser sensor as mentioned above, and the first measuring distance may be understood as a distance between an axis of the measured object and a fixed end of the measuring sensor. Here, the fixed end of the measuring sensor remains in position when the measuring sensor is deflected, which can be fixed by the sensor mounting bracket. It can be understood that the above-mentioned measured object may be a winding mechanism of any one of a coater, a winder, a roll squeezer, a printer, etc., and the radius of the measured object in the unreeled state may be obtained by querying the parameters of the device.
It should be noted that, the first measurement distance between the measured object and the measurement sensor herein, under the condition that the axis of the measurement sensor coincides with the axis of the measured object, may be directly acquired by the measurement sensor to obtain the measurement distance between the emission port and the surface of the measured object, where the measurement distance between the emission port and the surface of the measured object is the first measurement distance between the measured object and the measurement sensor. Of course, the first measurement distance between the measured object and the measurement sensor may also be obtained by actual measurement by a worker, which is not limited in the embodiment of the present application.
And 104, when the measured object is detected to be in the rolling state, acquiring a second measurement distance of the measured object based on the measurement sensor.
Specifically, after determining the radius of the measured object in the unreeled state and the first measurement distance between the transmitting port of the measuring sensor and the surface of the measured object, the measured object may be controlled to perform the rolling action, and when the measured object is detected to be in the rolled state and the rolling action is not performed any more within the preset time interval, the second measurement distance between the transmitting port and the surface of the current measured object may be acquired by the measuring sensor. The current state of the measured object may be determined by detecting whether the measured object rotates, and when the measured object does not rotate again within a preset time interval after the measured object rotates continuously, the measured object may be indicated to complete the winding action and be in the winding state.
It should be noted that, due to accumulation of machine running time and vibration of the device itself, the mounting position of the sensor deviates from the design position, and accuracy of the second measurement distance at this time cannot be ensured.
And 106, obtaining a first target winding diameter of the measured object based on the radius of the measured object in the unreeled state, the first measurement distance and the second measurement distance.
Specifically, after the radius, the first measurement distance and the second measurement distance of the measured object in the unreeled state are obtained respectively, a third measurement distance between the axis of the measured object in the unreeled state and the measurement sensor can be calculated according to the radius and the first measurement distance of the measured object in the unreeled state, and the radius, the second measurement distance and the third measurement distance of the measured object in the unreeled state can be input into a trained correction model to obtain the first target rolling diameter of the measured object. The trained correction model can be understood as a deep learning neural network, which can be trained based on the radius of the sample object with a known real roll diameter, the second sample measurement distance and the third sample measurement distance.
It may be understood that, in the embodiment of the present application, a calculation expression of the target winding diameter may be but not limited to be constructed in advance, and the radius of the measured object in the unreeled state, the second measurement distance, and the third measurement distance may be substituted into the calculation expression of the target winding diameter to obtain the target winding diameter of the current measured object, where the calculation expression of the target winding diameter may be referred to as follows:
In the above-mentioned method, the step of,target volume diameter which can be corresponding to the current measured object, < >>Can be corresponding to a third measuring distance, r can be corresponding to the radius of the measured object in the unreeled state, < >>May correspond to a second measured distance.
Reference may also be made herein to fig. 3 for a schematic diagram of the effect of a method for measuring a winding diameter for adaptively eliminating an installation error according to an embodiment of the present application. As shown in FIG. 3, the radius of the measured object in the unreeled state can be expressed as r, and the distance between the fixed end of the measuring sensor and the axis of the measured object can be expressed asThe distance to the surface of the measured object, which is acquired by the measuring sensor when the measured object is in a rolled state, can be expressed as +.>. It can be understood that the error angle between the corresponding measuring sensor of the measured object in the rolled state and the corresponding measuring sensor of the measured object in the unrolled state can be expressed as +.>That is, when the measured object is in the winding state, the position of the measuring sensor is deviated.
As an option of an embodiment of the present application, before the second measurement distance of the measured object is acquired based on the measurement sensor when the measured object is detected to be in the rolled state, the method further includes:
Determining a first position coordinate of the measurement sensor mapped on the reference plane;
after obtaining the first target winding diameter of the measured object based on the radius of the measured object in the unreeled state, the first measurement distance and the second measurement distance, the method further comprises:
determining a second position coordinate of the measurement sensor mapped on the reference plane;
a first error angle of the measurement sensor is calculated based on the first position coordinates and the second position coordinates.
In order to further improve the calculation accuracy and stability of the target coil diameter, an error angle can be introduced to control the installation error causing the coil diameter change. Specifically, when the measured object is in an unreeled state, the first position coordinate of the signal emitted by the emission port of the measuring sensor on the reference plane can be determined under the condition that the axis of the measuring sensor coincides with the axis of the measured object, wherein the reference interface can be perpendicular to the plane where the axis of the measuring sensor is located.
Further, when the measured object is detected to be in the rolling state, a second position coordinate of a signal emitted by the emission port of the measuring sensor on the reference plane can be determined, and a first error angle of the measuring sensor when the measured object is in the rolling state is calculated by combining the first position coordinate and the second position coordinate. In this embodiment of the present application, the point corresponding to the first position coordinate may be used as a right angle point in a right triangle, the point corresponding to the second position coordinate and the point corresponding to the transmitting port of the measuring sensor may be used as two acute angle points in the right triangle, and the first error angle of the measuring sensor compared with the initial state may be obtained.
Further, after obtaining the first error angle of the measuring sensor, an error calculation expression may be further constructed according to the first error angle of the measuring sensor and the above-mentioned second measurement distance between the transmitting port and the surface of the current measured object acquired by the measuring sensor, where the expression of the error calculation expression may be, but is not limited to, the following:
in the above-mentioned method, the step of,can be correspondingly error distance->Can be correspondingly a second measuring distance, +.>Can correspond to the first error angle of the measuring sensor and can be +.>As a function argument, ++>As a function dependent variable.
Further, a corresponding error distance-error angle change curve may be drawn according to the constructed error calculation expression, and an abscissa in the error distance-error angle change curve may correspond to different error angles, and an ordinate may correspond to an error distance corresponding to each error angle. It is understood that the error distance is herein understood to be the difference between the actual measured distance of the target roll diameter and the actual distance of the target roll diameter, and that the actual measured distance of the target roll diameter is greater than the actual distance of the target roll diameter.
Reference is also made herein to fig. 4, which is a schematic diagram illustrating an error distance-error angle variation curve provided in an embodiment of the present application. As shown in fig. 4, the implemented curve segment may correspond to a change curve of the error distance and the error angle when the error is not eliminated, and it can be obviously seen that the measurement error in the state of not eliminating the error is accompanied by the linear increase of the roll diameter, and the influence on the taper tension is also greater. The dashed curve segment can be correspondingly the change curve of the error distance and the error angle after the error is eliminated, and comparison can show that the change amplitude of the error distance along with the increase of the error angle is not obvious in the embodiment of the application, and compared with the corresponding error distance when the error is not eliminated, the error distance is obviously improved.
In order to further ensure the reliability of the error distance-error angle change curve, the measuring range of the measuring sensor can be obtained, and the obtained error distance-error angle change curve is located in the change range according to the change range of the error distance-error angle change curve of the measuring sensor. The change interval may be, but not limited to, a change interval of the error distance or a change interval of the error angle, which is not limited to the embodiment of the present application.
Taking a measurement range of 60 mm-600 mm as an example of a certain type of measurement sensor, the measurement resolution is more than or equal to 0.069 mm, and the diameter of the hollow shaft of the measured shaft is 200mm, the measurement range of the coil diameter of the measured shaft can be calculated as follows: 200 mm-1280 mm, and further determining the change interval of the error distance.
As still another alternative of the embodiment of the present application, after generating the error distance-error angle variation curve based on the error calculation expression, further includes:
when the measured object is detected to be in the rolling state again, determining a third position coordinate of the measuring sensor mapped on the reference plane, and acquiring a fourth measuring distance of the measured object based on the measuring sensor;
Calculating a second error angle of the measuring sensor based on the first position coordinate and the third position coordinate;
and determining an error distance corresponding to the second error angle of the measuring sensor in the error distance-error angle change curve, and obtaining a second target rolling diameter of the measured object based on the error distance corresponding to the second error angle of the measuring sensor and a fourth measuring distance of the measured object.
Specifically, when the equipment hardware computing resource corresponding to the measured object is higher, the corresponding target winding diameter can be calculated in real time according to the calculated error angle of the measuring sensor, so that the dynamic self-adaptive elimination of the error is realized. When the measured object is detected to be in the rolling state again, the second error angle of the measuring sensor is calculated by using the Pythagorean theorem, the error distance corresponding to the second error angle of the measuring sensor can be determined in the error distance-error angle change curve, and the second target rolling diameter of the measured object is obtained by combining the fourth measuring distance between the surfaces of the measured object acquired by the measuring sensor.
