The swing amplitude can be set, and the bulge problem can be solved. However, the material can generate left and right deviation in the production process, and the material is actually collected at the left and right limit positions of the swing amplitude in a deviation manner, so that the maximum position of the wrong winding layer is irregular.

step 4, delaying 1MS, controlling the actuator to operate leftwards at a constant speed by the deviation rectification, inquiring whether the edge of the material enters a negative deviation area, if the edge of the material enters the negative deviation area, indicating that a large deviation is generated in the production of the material, and performing acceleration processing to ensure that the maximum position of a rolling staggered layer is orderly collected;
step 5, delaying 1MS, controlling the actuator to operate rightwards at a constant speed, inquiring whether the edge of the material enters a positive deviation area, if the edge of the material enters the positive deviation area, indicating that a large deviation is generated in the production of the material, and performing acceleration processing to ensure that the maximum position of a rolling staggered layer is orderly collected;
and 6, entering the steps 4 and 5 to circularly operate.
Further, the step 4 continuously detects whether the material edge is at the positive blind zone threshold of the sensor, and stops when the material edge reaches the positive threshold.
Further, the step 5 is also used for continuously detecting whether the material edge is at the blind zone negative threshold of the sensor or not, and stopping when the material edge reaches the negative threshold.
Further, the positive threshold of the blind area is a boundary between a positive deviation area and the blind area.

step 3, delaying 1MS, controlling the actuator to operate rightwards at a constant speed by the deviation rectification, continuously detecting whether the edge of the material is at the negative threshold of the blind area of the sensor, and stopping when the edge of the material reaches the negative threshold; completing the first dislocation operation, recording the related information to be convenient for reference in the conventional operation;
step 4, delaying 1MS, controlling the actuator to operate leftwards at a constant speed by the deviation rectification, inquiring whether the edge of the material enters a negative deviation area, if the edge of the material enters the negative deviation area, indicating that a large deviation is generated in the production of the material, and performing acceleration processing to ensure that the maximum position of a rolling staggered layer is orderly collected;
