Automatic Single Shaft Tape Rewinding Machine

Rewinding Machine common fault - The platen roller does not move
1. Proportional valve is unstable. - Clean the proportional valve or replace the proportional valve to adjust the amplification signal.
2. Control failure - on-site debugging of the instrument.

Third, the function introduction
1. The tension control of the eject roller consists of a tension sensor and an eject motor.
In the loop control loop, the paper take-off motor is an electric motor when unwinding, and is a brake generator during normal operation and parking.
2. The pressure control of the pressure roller is controlled by various sensors such as the take-up roller diameter detecting sensor.
Forming a closed-loop control system, there are three pre-made curves for different paper grades and different finished paper diameters for the operator to choose, and the actuator will be controlled according to these three different pressure curves.
3, between the two take-up bottom rollers, take the torque difference control method, corresponding to no
The same take-up diameter, the torque between the front and rear bottom rollers is distributed in different proportions.

3 limitations of the original control system
This paper is aimed at the transformation of the rewinder analog DC drive system. The original rewinder control system mainly has the following shortcomings and limitations:
(1) The original rewinder control system is the DC drive control system of Siemens AG of Germany. Due to the DC motor drag, the analog regulator is adjusted, the device parameters are easy to drift, resulting in the reliability and accuracy of the rewinder, and Affect the quality and efficiency of rewinding, the maximum speed is only about 600m/min, it is difficult to meet the production requirements of high-speed paper machines.
(2) The original system uses mechanical buttons and instruments to operate and monitor the production process. The information integration capability is not strong. The process parameters of many production processes cannot be obtained, which increases the labor intensity of workers' operations and the time of manual participation in production, which affects the rewinding. Machine utilization and automation.
(3) The original system is a centralized system. A large number of I/O cables are distributed between the control room and the site, which not only increases the cost but also increases the system's unreliability.
(4) Due to incomplete information of field-level equipment, online fault diagnosis, alarm, and recording functions of field-level equipment are not strong. On the other hand, it is difficult to complete the parameterization functions such as remote parameter setting and modification of field devices, which affects the maintainability of the system.
