specific Embodiment

[0033] Based on the foregoing scheme, specific embodiments of the present invention are as follows:

example 1

[0035] see figure 2 , as can be seen from the figure, this example is a solution for motor control using the above-mentioned system. In this example, the entire control system consists of a PLC (200), HMI (300), two winding tension control devices (100) and two tension sensors (400).

[0036] In terms of composition and structure, the PLC is connected to the HMI, as described above in detail, and will not be described in detail here. At the same time, the PLC communicates with the two winding tension control devices 100 through the RS232 / 485 communication interface. Among the two winding tension control devices 100 , the first winding tension control device 100 a is connected to the servo driver 600 driving the take-up shaft 500 and the second winding tension control device 100 b is connected to the servo driver 800 driving the unwinding shaft 700 . The two tension sensors 400 are respectively used to detect the tension value at the end of the winding shaft 500 and the tens...

Embodiment 2

[0099] This example is a solution for magnetic particle control using the above system. In this example, the entire control system is composed of PLC, HMI, winding tension control device, tension sensor, magnetic powder amplifier and magnetic powder clutch.

[0100] Among them, the PLC is connected with the HMI, and communicates with the winding tension control device. The winding tension control device is connected with the tension sensor, and connected with the magnetic powder clutch through the magnetic powder amplifier. The magnetic powder clutch is connected to the winding shaft and the unwinding shaft.

[0101] The operating principle of each component in this example is the same as that in Example 1, and will not be repeated here.

Abstract

The invention discloses a winding tension control system. The winding tension control system comprises a programmable logic controller (PLC), a human-machine interface (HMI), a tension sensor and a winding tension control device, wherein the PLC controls and is connected with the HMI and the winding tension control device, the tension sensor detects the tension during winding in real time and transmits a detection signal to the winding tension control device, and the winding tension control device conducts calculation according to parameter requirements set by the PLC to form a corresponding control signal and transmits the control signal to a servo motor which drives a reel to be retracted / released. By the aid of the system, the precision and the effect of winding tension control can be greatly improved, and the efficiency of winding operation can be improved.

Description

technical field [0001] The invention relates to a winding control technology, in particular to a winding tension control system. Background technique [0002] In the fields of textile machinery, textile, leather, papermaking, metallurgy, film, packaging, battery, etc., the use of winding control devices is involved. The level of winding tension control is the key to the stability of the entire equipment and the quality of the product. where. [0003] The core technical issue of winding tension control has always been a difficulty and weakness in the field of industrial automation control. Most of the current solutions use PLC as the platform for PID control. Some engineers choose the built-in PID algorithm module of PLC, and some engineers choose to write the PID algorithm by themselves. [0004] The built-in PID algorithm of PLC is generally a standard PID, and the process of tension control is a dynamic process, and the unchanging PID algorithm is often difficult to adap...
