Solution

In the chemical industry, filling systems have achieved fully intelligent production through automation upgrades, significantly improving production efficiency. Adopting a multi-station synchronous operation design, the traditional single-line production mode has been upgraded to large-scale intelligent production, which not only greatly shortens the production cycle but also effectively reduces unit production costs through intensive resource management

The industrial filling and packaging automation system consists of three core modules: an intelligent filling system, an automated packaging system, and an intelligent logistics system. The intelligent filling system integrates functions such as automatic barrel positioning, rotation, lifting, laser position detection, and high-precision online weighing, achieving a precise automated weighing and filling process. The automated packaging system relies on real-time feedback of weighing data to complete fully automated online labeling operations. The intelligent logistics system achieves precise transport between workstations through roller conveyors, equipped with precise positioning and stop functions to ensure efficient and stable operation of the production line

       The filling system achieves a metering accuracy of ±0.2% through dynamic collaboration between a PLC intelligent control system and a high-precision weighing module. Furthermore, the automatic liquid filling and weighing machine for chemical drums requires a dynamic compensation algorithm to eliminate fluctuations in liquid flow and reduce the influence of material inertia, ensuring filling accuracy

Solution

The PLC and weighing module play a core role in the chemical filling and weighing machine. On the production line, precise conveying between workstations is achieved via roller conveyors. In this case, labels are first affixed to the chemical drums, and then the Huamao Auto AU3 IHR-3011-PNT reader reads the information on the labels to ensure the chemical drums are conveyed to the correct workstations

In automated chemical filling production lines, PLCs and high-precision weighing modules form the core of the system's control. The normal operation of the production line requires precise positioning and workflow of chemical drums via roller conveyors; the entire process is managed intelligently

1. Information binding and verification
   • First, attach RFID tags to the chemical drums to record product information
   • The Huamao Auto AU3 IHR-3011-PNT reader is used to automatically identify label data, ensuring that the barrelled materials match the workstation
2. Closed-loop control process
   • The PLC dynamically adjusts the filling volume based on real-time data from the weighing module
   • The conveying system uses reader feedback to achieve intelligent sorting and path control, ensuring that each chemical drum is accurately delivered to the target workstation

This system automates the entire process from information identification and precise filling to logistics delivery, significantly improving production accuracy and efficiency while meeting the stringent traceability requirements of the chemical industry
