Description

Field of technology. The present invention relates to the field of bottling equipment technology, in particular to bottling equipment and a bottling method. State of the art. A filling machine is a piece of equipment that dispenses a measured liquid into containers. Depending on the method by which the containers are fed into the filling machine, filling machines are divided into linear and rotary types. When filling on a linear filling machine, the containers move from one position to another along a linear path with pauses. When filling on a rotary filling machine, the containers rotate from one position to another with pauses. Linear filling machines, with their wide range of technical capabilities, have found widespread use in industry. For example, a Chinese patent application, Patent Publication Number CN 114132882 A, discloses a filling machine and filling method. It features multiple filling sections and weighing cells. Multiple filling sections effectively increase filling speed, while the weighing cells determine the total container weight. By connecting the weighing cells to the final filling section, the final section can determine whether the container is full. In this patent application, the weighing cell is installed only at the end of the filling zone. This configuration somewhat simplifies the design of the filling machine and increases filling speed. However, the accuracy of weight measurement is low, and accurate measurement of the material in the container is not guaranteed, making it impractical. Furthermore, if a weight error occurs, the container must be refilled, which does not actually improve filling efficiency. Furthermore, this patent application, like most filling machines, uses a method for weighing containers from below. Since coordination with the installation of the conveyor belt is required, this weighing method actually involves certain installation difficulties, which may affect the accuracy of the measurements.
