Problems solved by technology

[0007] Regardless of the use of tension sensors or linear speed sensors, it not only increases the equipment cost and limits the application occasions, but also requires different control modes and parameters to be set due to different feedback sources, making the current inverter tension control methods unfavorable for use control and use

Embodiment Construction

[0051] Relevant technical content and detailed description of the present invention, cooperate drawing description as follows:

[0052] See figure 2 It is a schematic diagram of the operation of the tension control frequency converter of the present invention to drive the motor to control the winding mechanism. In the tension control architecture of the winding mechanism, no tension sensor or line speed sensor is used, that is, there is no need to provide a tension feedback signal or line speed signal to the tension control inverter. The tension control framework of the winding mechanism mainly includes two frequency converters (being a first frequency converter 14 and a second frequency converter 24) and two motors (being a first motor 12 and a second motor 22), Used to control a controlled mechanical system 100 . The controlled mechanical system 100 is the winding mechanism, which mainly includes a first rotating shaft 10 , a second rotating shaft 20 and a winding object ...

Abstract

The invention provides a tension control module arranged in transducer and having a tension and speed close loop. Required tension feedback can be calculated in the transducer or can be realized by a feedback signal of a tension sensor. The tension control module is applied to tension control of a winding mechanism so as to drive at least one motor, thus driving the winding mechanism to rotate. The tension control module firstly controls the establishment of tension so as to carry out the tension balance control on the winding mechanism; and subsequently, the tension control module carries out speed adjustment control so as to carry out acceleration or deceleration control on the winding mechanism, thus ensuring that the winding mechanism can keep balanced tension stably during the winding process.

Description

technical field [0001] The invention relates to a tension control module, in particular to a tension control module built in a frequency converter with a closed loop of tension and speed. Background technique [0002] In the mechanical equipment of papermaking, metal products, textiles, plastic processing, wire and cable and other processes, it is a basic and important requirement to ensure the stable quality of the finished products by providing balanced tension control for the objects to be processed. [0003] The proportional-integral-derivative (Proportional-Integral-Derivative, PID) controller is quite valued and most commonly used in traditional industrial control. Because, the PID controller is not only simple in structure, but also easy to realize. It is worth mentioning that the PID controller can not only eliminate the steady-state error, but also obtain appropriate relative stability and damped characteristics at the same time. [0004] At present, most of the t...
