Liquid filling machine using open bus, field information acquisition, weighing system communication adopted automated filling system, project management, processing, archiving and establishment of documents. With humanized man-machine interface, provide convenience and also have a variety of protection functions, the user can set personalized working parameters according to the actual needs of the user can be set directly into the working state. Simple and convenient operation, no need to wait for restart and other complex operations.

Liquid filling machine adopts regulation to carry out the actual control of the weight of the program, according to the frequency converter operation mode to set its parameters, to achieve the purpose of automatically adjusting the speed of the PLC programmable controller in order to ensure that the filling process of the various parts of the device action of the accuracy and reliability of the PLC program is required to control the various weighing modules, relays, switches and solenoid valves. Integration of information technology accessory equipment, such as printers, scanning guns, RFID and other information identification equipment, to give the material into the weighing and dispensing process identifiable information.

Weighing and filling machine consists of locator program, monitor program, utility program startup, etc. After the startup system filling starts, the system carries out self-check to ensure the startup filling status is good through the processing and judging of the input weighing module signals. After each weighing system is ready, the host computer will call the memory recipe to the startup filling area, and then supply the startup according to the corresponding recipe.

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.
