Problems solved by technology

[0003] In the existing motion control system, unwinding and rewinding is to read the speed from the speed control device, such as frequency converter, DC speed controller, etc., so as to use the speed as a reference variable to compensate for large inertia and large friction. However, the rotational speed read from the speed control device is calculated and cannot fully reflect the size of the actual material roll, and there is a problem of inaccurate compensation

Abstract

The invention discloses a method for compensating inertia of a sensor in a rolling and unrolling system of a coating machine. According to the compensation method, the sensor is adopted for measuring a rolling diameter; a rolling diameter value is transmitted to an AD (analog-digital) conversion module, and the AD conversion module transmits a rolling diameter data signal to a PLC (programmable logic controller); and in the PLC, a corresponding rolling diameter value is taken as a control variable, a rotating speed is corrected, a set value of the corrected rotating speed is transmitted to an executing mechanism, and the executing mechanism automatically adjusts the rotating speed. According to the method for compensating the inertia of the sensor in the rolling and unrolling system of the coating machine, rolling and unrolling inertia and friction force can be accurately compensated, so that constant tension of a strip material is kept.

Description

technical field [0001] The invention relates to a control method in a coating machine, in particular to a sensor inertia compensation method in the unwinding and winding system of the coating machine. Background technique [0002] In the uncoiling and rewinding control system of the coating machine, the mechanical device for uncoiling and rewinding has a relatively large friction force, especially when the coil diameter is relatively large, the inertia is also relatively large, which requires a , Change the torque of the power equipment (motor) in real time, so as to prevent the loss of tension of the uncoiler and the failure of excessive tension of the coiler. [0003] In the existing motion control system, unwinding and rewinding is to read the speed from the speed control device, such as frequency converter, DC speed controller, etc., so as to use the speed as a reference variable to compensate for large inertia and large friction. However, the rotational speed read from...
