Counterweight type loop control system and method

Abstract

The invention provides a counterweight type loop control system and a counterweight type loop control method. The counterweight type loop control system comprises a loop front motor, a master commandmotor driver used for driving a master command motor of a production line, a loop front-mounted motor intelligent driver used for driving a loop front-mounted motor to run, a loop position sensor usedfor detecting a loop height signal, a loop height over-limit sensor set used for monitoring the overcharge and the overdischarge of the loop, and a man-machine interaction interface used for controlling the controlling the loop front-mounted motor through the loop front-mounted motor intelligent driver and displaying a current running state and a sound-light alarm signal. The method mainly comprises the steps of receiving a rotating speed signal sent by the master command motor and a detection signal sent by the loop position sensor by means of the loop front-mounted motor intelligent driver,calculating the given value of the rotating speed of the loop front-mounted motor, and correspondingly adjusting the rotating speed of the loop front-mounted motor. The system is simple in structure,low in cost, and convenient to realize and maintain. The switching and the automatic synchronous control of the counterweight type loop control mode are realized at a small cost.

Description

technical field [0001] The invention relates to the field of looper mechanism control of a continuous processing production line, in particular to a counterweight type looper control system and method. Background technique [0002] In the continuous processing production line of coil and strip, in order to realize continuous operation without stopping, usually a looper mechanism is set at the entrance section, exit section or process section of the production line. The unloading and unloading rolls or to ensure the constant tension of the process section. For the looper mechanism whose main command speed of the production line is not high and the speed dynamic change is not too large, a counterweight looper is usually used. The control system of the counterweight looper mainly realizes the balance of the amount of loops and the synchronous operation of the front and rear sections of the looper. At the same time, it also needs to have the functions of manual / automatic fillin...

AI Technical Summary

Problems solved by technology

Among them, the completely manual control device is difficult to match the difference in process speed between the front and rear sections of the looper, resulting in excessive dynamic changes in looper tension, which is likely to cause production accidents and affect product quality. Continuous and stable production; the control system composed of completely independent control devices has problems such as high equipment cost, complex system, and difficult troubleshooting
