The quantitative bucket scale is an intelligent Filling system designed for liquid bucket packaging. The Electronic scale is controlled by a programmable controller (PLC) and operated via a touch screen. It ensures that no liquid is filled into empty buckets and has functions such as not filling into buckets that are not properly aligned. The on-site management and control system based on single-chip microcontrollers, radio frequency cards, and network integration technology can provide real-time and effective control of material filling. It can achieve real-time detection of filling weight and real-time opening and closing of solenoid valves during the filling process, and upload data for effective computerized management. The electronic tags on the bucket bodies are read from the site and the tag codes are uploaded to the upper computer for identity verification. If the identity is valid, the next steps of switching the solenoid valves and filling will continue. During the filling process, the real-time weight data at the site is uploaded to the upper computer, which is then classified and summarized together with the tag codes. The upper computer communicates with the server and sends data to each filling site. 

The automatic filling scale has achieved electrical automation control. By adjusting the frequency of the motor, it can save energy and improve filling accuracy. The PLC control scheme is adopted, which facilitates the microcomputerized control of measurement and realizes networked production management. The weighing data can be displayed in the VB running screen in real time. At the same time, the weighing data can be stored in the database for query and traceability functions. This not only facilitates the supervision of the weighing process but also restricts the operations of the workers. Using the communication program between the upper computer and the weighing instrument, the weighing data is collected and stored in the Access database.
