First, the non-woven equipment plc logic processing capacity and operation processing capacity of the program, it is characterized by modularization, standardization and other programming methods, in the process of debugging or modification, but also only modify the corresponding module, so that it can be easy to read, hierarchical, more importantly, the debugging process. The PLC program is the key of a system running, decides the whole work organic carries on;
Secondly, the problem of human-computer interaction. In the main interface using the scripting language to realize the function shortcuts, click on the touchpad can be cut into the units of the extension of the screen, so that the realization of man-machine conversation. Production line is very fast, for synchronous implementation of the requirements is also high, in the design should take full account of this feature, so the use of synchronous control. The transmission frequency converter of the paving machine and winding machine is communicated data content, mainly through the PLC data interface. If we want to achieve satisfactory dynamic results, we must realize the digital communication and production line lifting speed is a good dynamic effect. In order to ensure the synchronous function between the network and winder, the winding machine also has a tension control system.
The tension of the winder is a very important part of the synchronous control based on the increase of tension control. Its function is very big, can affect the quality of the product to a large extent, and the stability of the winding machine tension is one of the factors. So, the tension controller is especially important, it can pass the control signal to the PLC, then through the tension control program, can regulate the tension controlling system tightly, ensure the winding machine tension control the dynamic and the stability.
The human-computer interaction system of touchscreen is also an important part of the production line. Touch screen provides a very advanced and user-friendly human-computer interface, when the operation on the touchpad click on the screen, and then will pop up the corresponding menu, very convenient. The dynamic drawing shows the main parameters and working state of the equipment in the work, and can be modified and set. The main include: Display function, parameter setting, historical trend record, alarm inquiry, Report making, authorization management and on-line help, etc.
