The Design and Application of Beverage Automatic Filling System

摘要

The paper presents the design and application of the beverage automatic filling system based on Siemens S7-300 PLC and MP277 touch screen. Photoelectric sensor was used to precisely detect positions of the beverage bottle, which it arrives the fixed position, servo motor will control it stop. The Siemens S7-300 PLC was designed by the software of Siemens STEP 7 5.4. Touch Screen was designed by the software of WinCC Flexible 2008, which it and PLC communicated by DP lines. The beverage automatic filling system can real-time display the state and set up the parameters of the object. It was proved by practice that beverage automatic filling system reduces labor intensity and operational cost, increases automation degree, and improves production efficiency.
