One FX2N32MRPLC is used to complete all mechanical operation actions and data processing.
FX2AD1 set, used to convert the analog value of the tension signal into the data amount for PLC to process the data. FX4DA1 set, output 1 is used for speed adjustment control, output 2 is used for tension control of feed shaft No. 1, and output 3 is used for tension control of feed shaft 2. One F940SW touch screen, used for man-machine communication, data input and display. 4 MG020 tension sensors. (Made in Italy RE) 2 MW.80.10 tension signal amplifiers (made in Italy RE) 2 MTC.16 power amplifier boards (Made in Italy by RE). It is not difficult to see from the above hardware structure that only a reasonable design of the control program can realize the perfect control system of man, machine, and electricity, and truly realize the high-end cutting machine with intelligent control of human power.
Its basic performance is as follows:
1. Tension control is realized by digital-to-analog / analog-to-digital conversion circuit, and the control program is professionally designed according to the characteristics of the bill slitter, so it has better control performance, and the control parameters can be specially set according to the products of different users , Can basically achieve tension-free adjustment operation. Greatly convenient for equipment users. The tension device adopts a split structure, so it can greatly reduce production costs. For manufacturers using Mitsubishi tension controllers, the manufacturing cost can be saved by about 20,000 yuan. (Omitting 2 LE-30CTA tension controllers and 4 LX-TD tension sensors (change to FTI type or MW type 2).)
2. Realization of intelligent tension control: Since the digital / analog conversion is used to process the tension signal, the comparison of the target tension and speed can be easily achieved. According to the comparison result, the tension can be adjusted in real time. Paper biting caused by tension changes during start-up and deceleration.
3. Multi-function display. The F940 man-machine interface can conveniently display the equipment running speed, shift output, cumulative output, distance to retreat, quantity per roll, length per roll, equipment working status, equipment failure, etc., and can display special functions according to user requirements.
4. The intelligent speed analysis function can make the parameter setting easier (only need to set the stop parameter, the deceleration parameter is automatically given by the computer). This function can effectively avoid the measurement inaccuracy caused by the randomness of operation. This function is very important for users who require accurate measurement of blank paper rolls.
5. The anti-copy function of the program can ensure that the interests of manufacturers are protected from imitations.
6. The logical operation benchmarking function makes the benchmarking operation more convenient and accurate, requiring only one roll to align.
7. The insertion knife control has been improved to completely eliminate the insertion knife with paper phenomenon.
8. The control system can be directly used for the direct upgrade and reconstruction of models like QF500 QF900 (equipment or imitation products made by Hengyang, Xinyu Xiangyu and other companies). (Single-layer and double-layer slitting machines can be used, and the tension control program can also be used for other rewinding and unwinding equipment.) There are too many functions to introduce one by one. If you are interested, you can write or call to get a free trial. The structure is different, there may be small changes, we will help you to complete the equipment installation and commissioning, technical staff training, to ensure that you produce qualified products.
Attached benchmarking procedure
1 Feed the paper, set the shutdown parameters, start the device, after shutdown, measure the upper and lower color mark errors, enter the error value, press the alignment key on the screen, the color marks will be automatically aligned.
2: Press the calibration key again to automatically cancel the standard. After the standard removal is completed, move the lower photoelectric switch to the color mark and press the compensation key to turn it on.
3: Start the equipment and take out the material shaft after stopping to see if there is any error. Just move the photoelectric switch by the same distance according to the amount of error. (The color code of the following layer exceeds the color code of the upper layer, then move down, and move up instead)
4: Start the device again, all adjustments are completed, if there is still a little error, just repeat the 3 actions. (Can be aligned once after proficiency)
