In this specification, a method of performing deviation rectification control on a target coil is provided, and this specification also relates to a system for performing deviation rectification control on a target coil, a computing device, and a computer-readable storage medium, which are described in detail in the following embodiments.
Referring to fig. 1, fig. 1 shows a flowchart of a method for performing deviation rectification control on a target coil according to an embodiment of the present disclosure, where the target coil includes two edges parallel to a conveying direction, and the edges are provided with at least two color patch sensors, and the method is applied to a system including the color patch sensors, the photoelectric sensors, the driver, and the controller, and specifically includes the following steps.
Step 101: the controller judges whether the target coiled material is subjected to position deviation according to the photoelectric sensor in the process of conveying the target coiled material.
The target coil includes two edges parallel to the conveying direction, and it is understood that the conveying direction is the length direction of the target coil after being unwound.
The photoelectric sensor is used for detecting whether a target coiled material enters a preset detection area or not and whether the target coiled material deviates from the preset detection area of the photoelectric sensor or not; the color code sensor is used for detecting information such as edges, mark lines or mark edges of the target coiled material; the driver is used for adjusting the position of the target coiled material according to the edge of the target coiled material received from the controller and the deviation correcting direction, so that the edge of the target coiled material is conveyed along the preset position.
In one implementation, in order to determine whether the target coiled material is shifted, the current deviation rectifying center pixel point of the target coiled material needs to be detected by a photoelectric sensor, and then the current deviation rectifying center pixel point and the preset deviation rectifying center pixel point are used for judging, so that whether the target coiled material is shifted or not is rapidly determined, and deviation rectifying control is performed, and the specific implementation mode is as follows:
the controller judges whether the target coiled material is subjected to position deviation according to the photoelectric sensor in the process of conveying the target coiled material, and the controller comprises the following steps:
the controller determines the current deviation rectifying center pixel point of the target coiled material according to the position information of the photoelectric sensor;
and calculating a difference value between the current deviation correcting central pixel point and a preset deviation correcting central pixel point, and judging whether the target coiled material is subjected to position deviation or not according to the difference value.
Specifically, under the condition that the difference value between the calculation based on the current deviation correction center pixel point and the preset deviation correction center pixel point is larger than a certain difference value threshold value, the position deviation of the target coiled material can be determined.
For example, if the absolute value of the difference value between the calculated current deviation correcting center pixel point and the preset deviation correcting center pixel point is greater than the difference value threshold 5, it may be determined that the target coiled material is shifted.
Optionally, determining that the target coiled material is shifted in position based on the fact that the current deviation rectifying center pixel point is different from the preset deviation rectifying center pixel point.
Step 102: after determining that the target coiled material is subjected to position deviation, acquiring the edge and the deviation rectifying direction of the target coiled material based on the color code sensor.
Specifically, after the photoelectric sensor judges that the position of the target coiled material is deviated, the controller sends an instruction to the color code sensor, and further obtains the edge and deviation rectifying direction of the target coiled material through the color code sensor,
in one embodiment, before the deviation rectifying control of the target coiled material is performed, the color code sensor needs to be set, so that the edge and the deviation rectifying direction of the target coiled material can be more accurately determined after the position deviation of the target coiled material occurs, and the specific implementation manner is as follows:
before the controller determines whether the target web is positionally shifted according to the color code sensor during the target web transport, the method further includes:
the controller responds to a color code setting instruction, sets a first color calibration on one color code sensor and sets a second color calibration on the other color code sensor.
The first color calibration may be a color calibration corresponding to the target coiled material, and the second color calibration may be a color calibration other than the color calibration corresponding to the target coiled material.
Specifically, according to the received color code setting instruction, the controller can set a first color calibration of the corresponding color calibration of the target coiled material in one of the two color code sensors arranged at the edge of the target coiled material, and the first color calibration is used for detecting whether the target coiled material exists in the range of the color code sensor, and set a second color calibration outside the corresponding color calibration of the target coiled material in the other color code sensor.
After the first color calibration and the second color calibration are set, the edge and the deviation correcting direction of the target coiled material can be detected through the color code sensor, and the specific implementation mode is as follows:
the controller obtains the edge and the deviation rectifying direction of the target coiled material based on the color code sensor, and the controller comprises:
the controller determines the edge of the target coiled material based on the first color calibration and the second color calibration through the color code sensor, and determines the deviation correcting direction of the target coiled material based on the duty ratio information of the first color calibration and the second color calibration in the current scanning range of the color code sensor.
Specifically, the color mark sensor determines the edge of the target coiled material based on the difference between the first color calibration and the second color calibration, and determines the offset direction of the target coiled material through the range information of each color calibration of the first color calibration and the second color calibration in the current scanning range of the color mark sensor, thereby determining the deviation rectifying direction of the target coiled material.
In one implementation, the deviation correcting direction of the target coiled material is determined based on the ratio information of the first color calibration and the second color calibration in the current scanning range of the color code sensor, and the deviation correcting direction can be determined by determining the ratio of the respective ratio information of the first color calibration and the second color calibration, and the specific implementation is as follows:
the determining the deviation rectifying direction of the target coiled material based on the first color calibration and the second color calibration and the duty ratio information of the second color calibration in the current scanning range of the color code sensor comprises the following steps:
and determining the deviation rectifying direction of the target coiled material based on the ratio of the first duty ratio information of the first color calibrated in the scanning range of the color scale sensor to the second duty ratio information of the second color calibrated in the scanning range of the color scale sensor.
Specifically, the controller obtains first duty ratio information of the first color code defined in the current scanning range of the color code sensor through the color code sensor, and second duty ratio information of the second color code defined in the current scanning range of the color code sensor, further judges whether the ratio is larger than a preset duty ratio threshold value based on the ratio of the first duty ratio information to the second duty ratio information, and determines the deviation rectifying direction of the target coiled material by combining the edge of the target coiled material under the condition that the ratio is smaller than the preset duty ratio threshold value.
For example, the ratio obtained by dividing the first duty ratio information by the second duty ratio information is 1.5, which is smaller than the preset duty ratio threshold 4, and the edge of the target coiled material is the right edge and is more than the left edge, so that the target coiled material can be determined to deviate to the left, and further the deviation rectifying direction of the target coiled material is determined to be required to rectify to the right.
Step 103: and controlling the driver to perform deviation rectification control based on the edge of the target coiled material and the deviation rectification direction.
Specifically, the controller generates a deviation rectifying instruction based on the obtained edge and the deviation rectifying direction of the target coiled material, and sends the deviation rectifying instruction to the driver to control the driver to carry out corresponding deviation rectifying control operation on the target coiled material.
The controller in one embodiment of the specification judges whether the target coiled material is subjected to position deviation according to the photoelectric sensor in the process of conveying the target coiled material; after determining that the target coiled material is subjected to position deviation, acquiring the edge and the deviation rectifying direction of the target coiled material based on a color code sensor; the edge and the deviation rectifying direction of the target coiled material are obtained through the color code sensor, so that the edge and the deviation rectifying direction of the target coiled material are accurately rectified based on the edge and the deviation rectifying direction control driver of the target coiled material, and secondary damage to the coiled material is avoided.
