Today’s Patent – Ton Bag Loading Weighing Device

The said invention (CN216834371U) was invented by Ren Xianquan Yu Yanan Fu Qiang Chen Yonglong, patented by USPTO on 23-02-2022. Currently, it stands assigned to Cosmoplat Industrial Intelligent Research Institute Qingdao Co Ltd.

Current ton bag charging and weighing devices utilize manipulators to grasp and move the ton bags to the appropriate position, where the bags are inflated for filling and sealed using complex mechanisms like welding. These systems, while functional, are characterized by their complicated structures, high energy consumption, and frequent fault occurrences. This complexity not only increases operational costs but also reduces efficiency due to the high rate of malfunctions.

The proposed ton bag charging and weighing device simplifies the overall structure by integrating a lifting mechanism with a first air cylinder and a supporting part that moves vertically. It also features a bag hanging mechanism with hinged arms and hooks for efficient bag handling, and a weighing sensor for precise weight measurement. This design allows for adaptable use with different bag specifications and streamlines the unloading process through a rotating bag arm, enabling easy removal by a forklift. By reducing mechanical complexity and the number of moving parts, this device minimizes fault rates and manufacturing costs while enhancing operational efficiency.
