一、preface
In today's era of science and technology with each passing day, to meet the requirements of the modern people on the packaging of goods, the accuracy of the location of the packaging production line is increasingly high. The application of all kinds of advanced technology in the packaging line, in order to achieve the high automation and high efficiency of packaging production line is imminent. And David a fly ECF300 vector converter control high precision, fast response speed, strong anti-interference. It with PLC together with the application of form closed loop position controller has very important significance in packaging line. It solves the problem that the initial positioning is difficult, the positioning error is large, the dynamic adjustment is slow, and the transmission is easy to dislocation, and so on.

 

二、Process flow of ceramic tile packing machine
At present, the process of packaging in the domestic tile tile manufacturers include brick, detection, brick, paper feeding, origami, and packaging process, in which the
Inverter control is the highest in the process of conveying the ceramic tile. In the ceramic tile conveying process, requirements inverter start, stop, speed is fast and smooth, so as to guarantee in the transfer of ceramic tile ceramic tile can not slide; and each parking position error is less than 2 mm, so as to ensure each action of the smooth, accurate, molding and packaging products appearance. In order to ensure that each time the location of the machine is down, the frequency converter needs to be matched with the PLC and the encoder. PLC real-time calculation of the position of the ceramic tile operation, according to the position of the ceramic tile to the frequency of different pulse signals. The highest pulse frequency was 50kHz, the lowest was 0Hz.

 

三、Advantages of ECF300 application in packaging machinery
1) perfect PUL count port, can accept 100kHz pulse signal.
2) plus deceleration process is very smooth, motor noise is very small.
3) the precision of the current and voltage limiting function, thus ensuring the accuracy of the location.
4) using the latest generation of high-speed motor control of the DSP, and the use of dual core processing technology, ECF300 in all aspects of the response speed is very fast.

五、Concluding remarks
It is widely used in many Foshan ceramic tile packaging equipment factory, David chuangfei ECF300 vector inverter has been recognized by everyone.
