A laminator is a device that glues two sheets of paper together. Generally, it consists of a paper feeding mechanism, a paper mounting mechanism and a paper pressing mechanism. Our motion control scheme is applied to the alignment part of the laminating mechanism. The deviation of the top sheet and the bottom sheet sent by the sheet feeding mechanism is obtained through four types of photoelectric acquisition, and then the two alignment servos are controlled to correct the top sheet at high speed, so that the The face paper is accurately attached to the backing paper, so as to achieve high-speed and high-precision sticker control. The bottom paper feeding part receives the photoelectric signal of the paper, and after an appropriate delay, accurately sends the paper to realize the control of a face paper and a bottom paper, and realizes a stable and reliable sticker function.
The motion controller adopts: DSP FPGA solution, high-speed and high-precision control requirements, DSP processing cycle is 125us, using photoelectric signal acquisition FPGA hardware high-speed processing, not affected by software scanning cycle, to ensure the reliability of high and low speed capture of the bottom paper position difference, Guarantee high-speed deviation correction accuracy. Support main line speed: 150m/min, 15000 sheets per hour.
When using the system, you only need to set the required mechanical parameters to operation and control, and then the operation can be started. It supports single-sided paper mode and single-sided paper mode, which is convenient for machine installation and debugging.
The system includes alarm functions such as top paper jam alarm, bottom paper jam alarm, top paper bending alarm, bottom paper loss alarm, etc. Each function has a separate switch to select whether to output an alarm stop signal.
The monitoring contents include: real-time left and right alignment correction value, bottom paper parallelism monitoring, photoelectric signal quantity monitoring, encoder monitoring, servo alarm monitoring, top 50 production monitoring, etc., to assist customers in debugging equipment. When an exception occurs, assist in investigating the problem.
The high-speed laminating machine control system has the functions of high speed, high precision and high real-time performance. The system monitoring is rich, the operation interface is simple, and the customer is easy to use.
