ABSTRACT
This design mainly describes the control method and principle of PLC and automatic bottling，adopts a new detection method，realizes the automation of the whole production line. In this paper，the design steps of automatic bottling control system are discussed in detail. By fully understanding the automatic bottling system，taking the current situation of the industry as the starting point，combined with the application of automatic control technology in other industries，The basic structure of automatic bottling control system based on PLC is presented. The automatic control of multi-valve opening，bottle breaking detection，bottle pick-up，automatic cap pressing and so on is designed with programmable logic controller (PLC). Finally，the configuration software is introduced briefly，and the simulation process is carried out. A detailed description is given and a configuration screen of the automatic bottling control system is attached. The hardware configuration and software design of the automatic bottling control system are completed in the design of the system，and the real-time monitoring system is designed by using the configuration software.
The automatic bottling control system of mineral water is designed based on FX2N-32MR PLC. The design of the system includes hardware and software. The hardware design mainly includes the design and installation of Mitsubishi FX2N-32MR PLC external circuit，and the software part includes program design and debugging. Finally，the system can achieve the following functions: (1) delivery of empty bottles，automatic bottle loading according to the size of empty bottles design to determine; (2) carrying on the transmission and statistical quantity to the full bottle，the counting content includes accumulative，the unit packing quantity can be determined according to the packing size design; (3) can ensure manual reset. The system adopts Mitsubishi programmable controller，sensor，relay，stroke switch and other electrical components. The automatic control of automatic bottling process of mineral water can be realized by using good automatic control of PLC.
Key words: automatic bottling of mineral water，production line，automatic control
