The main electrical control part of the filling machine is a Siemens S7300 series PLCCPU317-2PN/DP. The filling valve control part is a control system module EX484. Siemens PLC is responsible for the safety functions, speed control, high level buffer tank level control, return cycle heating, CIP in-situ cleaning, height adjustment, signal exchange, etc. The control system is composed of Siemens PLC buses. Siemens PLC control system consists of two buses, Profibus and ASI bus. The filling machine is responsible for filling valve metering cylinder level control, tank filling level control, filling valve pneumatic control, filling angle time control and so on. The filling valve control is composed of two buses: Powerlink bus and CANbus bus.

The filling machine calculates the position information of the circular filling port in the image of the barrel cover surface, namely the filling port radius, the filling port center mark and the height of the oil gun. The corresponding position information is transmitted to the stepper motor control system, and the motor control system drives the shaft stepper motor according to the pulse instruction issued by the computer, and drives the oil gun to run above the filling port to realize automatic positioning and filling.

Propanol filling machine is driven by stepping motor to drop down to reach the lower limit position, the well is signaled by the travel switch, and the PLC controls the filling valve to open fully for filling. The use of local area network realizes the communication between the field computer and the equipment, through the RS485 network can communicate with the filling machine each other. The use of multiple filling machines can easily constitute a RS485 distributed control system network.

The ton barrel filling machine adopts manual and automatic control scheme, PLC is responsible for collecting the target value input signals and sending control commands to the actuator after program processing. The material filling display window is established, database variables are created and attribute definitions are completed. Through the means of attribute definition, space, strategy, etc., complete the design of dynamic screen, set up the storage attributes of data variables, establish data query and curve browsing. Establish communication connection and parameter setting of external equipment to realize remote monitoring and data management function.

The liquid filling system is digitally processed by a computer or a dedicated image processing module, which performs the recognition of size, shape, color, etc. based on the information of pixel distribution, brightness and color of the image. The weight of the converted liquid is transmitted to the metering and filling mainframe through a functional relationship measured by the weighing module, and this data is compared with the mainframe's rapid collection, real-time processing, and the settings of the corresponding components in the recipe.

The cream canning machine realizes the quantitative filling of liquid by collecting the data from the weighing module. It needs to measure the filling quantity and display it in real time. The filling system adopts weighing module and weighing instrument to realize the measurement of canning quality. In order to ensure the filling accuracy, the system adds a solenoid valve at the front end of the pump to ensure that the liquid inflow can be turned on and cut off immediately when starting/stopping.

Weighing Liquid Filling Machine provides filling throughput by gravity or by using a pump to fill, moving continuously through different filling, capping, etc. It is a complete set of automated equipment for weighing and filling control by using high-precision electronic scale measuring device, electrical control management and visualization man-machine software configuration. The weight and filling control of the material loaded into the container is carried out through the monitoring system and the PLC program, thus realizing precise metering and filling.

Liquid filling machine all by the full computer filling, feeding, discharging, replenishment control touch screen control, control system can control multiple weighing and filling machine filling operations at the same time, the reaction tank can be formulated several to dozens of materials, can be displayed at the same time the dosage process and print the name of each material, quality, total mass, cycle time, formulas, daily reports, monthly reports and so on.

The weighing and filling machine adopts computerized automatic control of weighing, double-speed filling (fast filling at the beginning and slow filling when the electronic scale is close to the target amount) to ensure the filling accuracy, and adopts automatic quantitative filling to control the filling operation of raw materials in barrels. The automatic filling machine is a comprehensive automatic filling control system integrating computerized production process control and data management with weighing and filling, filling control and discharge.
