[0045] The intelligent quantitative packaging machine control system of the present invention is as follows: Figure 1 As shown, it mainly includes a quantitative weighing unit, an electrical control unit, an Internet of Things communication unit, and a packaging execution unit.

[0046] In the intelligent quantitative packaging machine control system as described above, the quantitative weighing unit can be a combination of an analog weighing sensor and a weighing transmitter, or a digital weighing sensor, wherein the weighing transmitter and the digital weighing sensor need to support industrial Ethernet communication protocols such as Modbus TCP / IP or PROFINET.

[0047] As described above, in the intelligent quantitative packaging machine control system, the electrical control unit is mainly composed of a programmable controller, electrical protection components, motor control components, etc. The programmable controller needs to support industrial Ethernet communication protocols such as Modbus TCP / IP or PROFINET, collect weighing data at high speed through the programmable controller, and control the quantitative packaging process in combination with an adaptive intelligent control algorithm. The adaptive intelligent control algorithm continuously adjusts the control parameters according to the collected data. For example, when it is detected that the material flow rate is accelerated, the closing speed of the feed valve is automatically increased to ensure that the feed is stopped in time when the set weight is reached. For example, when it is detected that the metering result exceeds the weight tolerance, the metering parameters are automatically adjusted, that is, the rapid feeding target value is reduced to ensure sufficient fine feeding amount to improve the metering accuracy. Figure 2 and Figure 3 As shown, Figure 2 This is a schematic diagram of the structure of a typical powder material quantitative packaging machine. Figure 3 This is a schematic diagram of the structure of a typical granular material quantitative packaging machine.

The configuration data is connected to PIMS (Production Information Management System) to manage production processes and resource allocation.

[0049] The intelligent quantitative packaging machine control system as described above, in which the packaging execution unit is configured differently according to the material characteristics, is a mature technical solution.

For fully automatic packaging production lines, the system automatically starts the production task according to the task.

[0052] 2. System initialization: When starting the packaging machine, perform equipment self-check and parameter initialization to ensure that all components work normally and load the preset packaging parameters according to the production task instructions.

[0053] 3. According to the material characteristics and quantitative requirements, the motor control element of the electrical control unit controls the feeding speed and amount of the feeding unit to ensure a stable supply of materials.

[0054] 4. Quantitative control: The sensor in the quantitative weighing unit is used to monitor the material quantity in real time. Combined with the adaptive intelligent control algorithm, the electrical control unit accurately controls to achieve the preset quantitative value.
