Liquid filling scale and the collection of various types of data processing and server data exchange to achieve data sharing. Monitoring management is through the computer technology network technology database management system and software technology, filling data and monitoring information centralized processing, so that its daily work, such as sending and receiving, turn and other operational procedures, standardization, institutionalization of each step of the operation of the law can be relied upon to have a basis for checking the management loopholes to be eliminated.

Liquid filling machine through the RS-422/485 interface can be fast communication and setup, hardware configuration and external wiring part of the expansion of analog input and output modules, its programmable controller switching inputs and switching outputs with networking and communication capabilities, you can use the PLC comes with a basic control unit to design its start and stop.

Liquid filling machine adopts the distribution switch quantity input, analog quantity input signal real-time acquisition of filling quality, switching quantity output control pump and solenoid valve action, PLC system has two ways of working, using the main program call subroutine structure, reduce scanning time, measured value conversion, stop and emergency stop external management.

Liquid filling machine will be sent to the filling position of the empty barrel, the mouth of the barrel and the mouth of the spray gun aligned with the filling machine gun driven by the cylinder into the barrel; liquid filling scale when the detection of the spray gun in place, the bottom valve opens, nitrogen filling valve start to dry nitrogen through the filling port into the barrel, so that the air in the barrel by the nitrogen replacement, and at the same time, can accelerate the drying of the barrel inner wall, to ensure the safety of the filling.

Liquid filling machine to send information to the weighing system through the serial port to read the weighing data after the weighing system in receiving such information, will be through the RS232 serial port to the microcontroller's serial port to send the data, automatic filling machine (fixed capacity and fixed weight type) of the verification can be completed through the weighing method, the use of the with a serial port (RS232) based on the VB platform to prepare, its functions include data acquisition, data processing, The functions include data acquisition, data processing, file generation, and data printing.

The diluent filling machine is composed of conveying, filling machinery, inkjet machine and palletizing machine. The filling is composed of two parts: No. 1 filling station and No. 2 filling station. The whole process only needs manual loading and capping.

The control system of the quantitative filling machine mainly consists of PLC, touch screen, actuators, and detection elements. The computer downloads the program and monitors the operation of the equipment through the Ethernet PLC on-line. The touch screen communicates with PLC through Modbus485 communication protocol, displaying the running status of the equipment, and starting and stopping the equipment to set the operating parameters and other operations. The actuator is responsible for the execution of the PLC instructions, the specific implementation of the corresponding action. The detecting element sends the status and parameters of the equipment to the PLC.

The automatic filling machine consists of programmable controller and electronic scale to form a two-stage computer control network, integrating automatic control technology, electronic scale measurement technology, weighing module sensor technology, computer management technology in an integrated mechatronic control system; adopting open control mode, strong compatibility and open database. It can be accessed to factory LAN through Ethernet, which can realize the integration of management and control. It has the advantages of digital display of weight value, dynamic display of process screen, formula modification management, fast filling speed, high control accuracy, etc. It adopts the upper computer completely on-screen control system, with the functions of automatic storage of filling data, inquiry of list of filling process, and statistics and printing of class, day, month and year reports.

The weighing and filling machine integrates computer technology, automatic control, communication technology and weighing technology into one, and adopts programming software and field equipment library in accordance with IEC-1131 international standard, providing continuous control, sequential control and high-level language. The field device library provides a large number of commonly used field device information and function blocks, which can greatly simplify the configuration work and shorten the engineering cycle. SCL can be used to program user function blocks, using the IEC-1131 standard, the function blocks generated by SCL can be called many times in the CFC. The user can program the mathematical model of the process and the optimal control strategy into function blocks with SCL and download them directly into the controller. In this way, the optimized control of the process can be fully realized.
