The weighing and distributing machine transforms into 4~20mA current as the input signal for system display and control through the weight transmitter. The current weight of the raw material barrel is taken as the starting weight setting value, and is set as the target dosing value through the display instrument or DCS system. When the weighing module detects that the weight in the canned barrel rises up to a certain value, at this time, the output current is basically in a linear relationship with the weight value, and in order to ensure the accuracy of each point, the liquid level signal of the filling barrel is taken as the control signal of the feeding valve for automatic adjustment of the liquid level parameters. In order to ensure the accuracy of each point, the liquid level signal of the filling barrel is used as the control signal of the feeding valve for the automatic adjustment of the liquid level parameter, so that the whole automatic filling machine realizes the automatic adjustment function of the continuous production process.

The automatic distribution system adopts configuration king software, programmable controller and electronic scale to form a two-stage computer control network, weight control through PID regulation, according to the deviation of the falling material, using proportional, integral, differential calculation of the control error, through the frequency converter to regulate the speed of the motor, adjusting the amount of feed to make it equal to the set value, to complete the automatic filling process.

Automatic distribution machine to achieve all signal acquisition, calculation, regulation, respectively: temperature control, traction control, pressure control and auxiliary control of the local unit, mainly installed WinAC adapter and unit status monitoring, process data access, unit automatic filling control, and shop level process control server and production planning server connected.

The metering and distribution machine realizes the control of fast, medium and slow valve closure, and the cylinder stroke is controlled by PLC signal to complete the actions of weighing, filling, opening, opening, closing and capping. When the weighing module reaches the given weight value, the opening cylinder returns to the filling valve and closes the opening cylinder to move to the given position, the opening cylinder moves upward, and the valve cover is installed. By driving a piston through the cylinder to draw and pump out the material, the flow direction of the material is controlled by the check valve, the stroke of the cylinder is controlled by the magnetic spring switch to adjust the filling amount, the weighing module is connected with the data line of the weighing instrument, and the pressure signal of the electronic scale is continuously transmitted to the weighing instrument during the measurement process, and the control instrument controls the pump and closes the pneumatic valve when the preset quantitative weight is reached.

The quantitative distribution machine realizes the acquisition, calculation and adjustment of all signals, respectively: temperature control, traction control, pressure control and auxiliary control of the local unit, mainly installing WinAC adapters as well as unit status monitoring, process data access, automatic filling control of the unit, and connecting with process control servers and production planning servers at the workshop level.

Explosion-proof dispenser utilizes the analog input template in PLC to collect real-time data on the site, calculate the actual standard filling value according to the weight of each weighing system, and save the value of the converted value for calculation to minimize the fluctuation of the weight to facilitate the application of numerical values and PID loop adjustment to ensure the accuracy of the adjustment of the falling error. The PLC output is controlled by three ways of rationing, dosing and frequency giving to the on-site frequency converter. When the operator selects rationing on the operation screen, he only needs to input the total weight of filling and the rationing ratio of each sub-scale, and then the amount of discharging of each scale can be calculated automatically, and tracking adjustment can be carried out according to this discharging amount.

The distribution system sends the name, station number, quantity and other information of the material to the LED screen display through the communication of INTERBUS field bus, and at the same time, starts the music ringing and lights up the indicator of the corresponding material on the station and the light box. After the warehouse staff get the information, press the corresponding button under the light box indicator to answer, then the light box on the light box corresponding to the material's indicator light is off, indicating that the information is confirmed to have begun to feed. According to the confirmed information, the bus controller will turn the indicator light above the button of the workstation from constant light to flashing state, indicating that the material is being fed. When the material arrives at the called station, the operator restores the button to the disconnected state and the indicator light goes out, indicating that the material delivery process is finished.

Automatic filling machine is composed of industrial control machine, cylinder actuator and weighing module, which is mainly used for monitoring the assembly line process device and related data management and filling to ensure that the equipment to complete the expected operation, and its main function is to realize accurate measurement of product materials. Realize intelligent filling process management control. Establishment of software serving the automated process control using computer recognition technology, printing technology, automatic control technology, information technology, the formation of intelligent automatic filling, to meet customer requirements for the filling process automation, information technology, intelligent.

Weighing and filling machine when the liquid level in the storage tank in the lower liquid level (lower limit value) and below, the float pressure plate detached from the mechanical valve and pneumatic butterfly valve open, through the inlet to the storage tank to transport liquid materials, with the liquid level rising, the float assembly according to the direction of the arrow to rotate, when the liquid level in the storage tank to reach the upper liquid level (upper limit value), the float pressure plate pressure down the mechanical valve contact and the pneumatic butterfly valve closes, to stop to the When the liquid level in the liquid tank reaches the upper level (upper limit value), the floating ball pressure plate presses down the mechanical valve contact and the pneumatic butterfly valve to close, stopping the delivery of liquid materials to the liquid tank. The filling system is controlled by pneumatic valve, mechanical valve and pneumatic butterfly valve.
