1 . Overview
high-speed automatic with page after printing machine is an important part of processing, it is through the printing, folding after the posts were on the books with each page with page-station machine, run set when the order will be different according to the book collection into high posts automatically quote the entire book; machine with the largest page-position 24, with a maximum speed of 10,000 posts pages / hour, the book range from 196X135 to quote size 460X230mm;
can automatically detect the block station. empty posts. double fault and automatically posts emission, will quote the book with page fault auto emission port from the output of the posts with more than books with pages , they can manually add posts or insert processing; page in a choice of 1:1 with a continuous interval with 1:2 with a page or pages of books in the production of Posts when the production rate of less doubled ShuTie transmission is established type transmission, the friction can be reduced print runs to reduce the time to take posts; fault and yield production status information can be displayed in the Chinese text display, running at a glance.
control system selected Schneider Twido series PLC, the text display. inverter. close. Optoelectronics. travel switch. contactor. relay. Switches;
Twido PLC is the device s control center, through the Modbus communication to the station connected organically to achieve high-speed distribution system pages, Yield. time and space station posts. double posts . blockage detection, real-time fault in the operation of Chinese terminal display; the entire control system simple and clear structure, greatly improve efficiency, reduce the I / O points and wiring, reducing costs, a clear display condition information.
2. Control System Overview
Twido modular mainframe can support two RS485 communication ports, CPU on the programming port is used and the upper operation panel TSX08H04M Chinese text communications, communications expansion module on the first two communication ports to achieve through the Modbus and Page sub-station together with control, up to 24 station, take joint control of seven sets of input and output points Twido close to 300.
Control chart are as follows (page 12-station machine with an example):
Twido PLC-modular expansion IO 20:00
TSX08H04M four lines of text display Inverter ATV58-control machine drive motor
ABL7 RP switching power supply photoelectric switch XU, close. Travel switch
3. Conclusion <BR> the control system of Twido PLC as, brought many benefits to customers, mainly as follows:
1. modular body, save installation space.
2. transistor output frequency is high, with pages to improve efficiency. Up to 10,000 / hour.
3. multiple Twido PLC flexible networking, electronic control system configuration is more flexible to adapt to different work requirements on the system volume
In short, the control system complete with Schneider industrial automation products, compact structure. system reliability. Modbus communications link, greatly reducing control costs and improve productivity.
