The granted patent US12042817B2 describes a comprehensive glue dispensing system designed to enhance the efficiency and reliability of glue application processes. The system comprises two feed tanks connected to a control valve, a glue dispensing needle cylinder equipped with a dispensing valve, and multiple fluid level detecting units. These detecting units monitor the glue levels in the needle cylinder and both feed tanks, ensuring that the dispensing process is maintained without interruption. The system allows for the use of various types of control valves and fluid level sensors, which can be proximity switches, capacitive transducers, or optical sensors, providing flexibility in design and application.

Additionally, the patent outlines a method for supplying glue that involves detecting fluid levels and managing the flow from the feed tanks to the needle cylinder. The method includes steps for replenishing glue when levels fall below predetermined thresholds, stopping the dispensing process when necessary, and issuing alerts for tank replacements or refills. The system can also incorporate additional feed tanks and glue dispensing cylinders, further expanding its capabilities. Overall, this patent presents a sophisticated solution for automated glue dispensing, aimed at improving operational efficiency in various industrial applications.
