The patent US12043431B2 describes a transfer element designed for integration between a dosing device and a filling device in tubular bag machines. This transfer element features an input station, a dispensing station, and multiple transfer containers. It facilitates the transfer of a specified quantity of filling material from the dosing device to the transfer containers at the input station. The transfer containers are then moved along a transfer line to the dispensing station, where the filling material is dispensed into the filling device. The system is controlled by a transfer control system that manages the transfer process based on the position and speed of the transfer containers, ensuring efficient operation.

Additionally, the transfer containers are equipped with an adjustable seal that can transition between closed and open positions, allowing for the storage and gravity-assisted transfer of filling material. The design includes features such as an adaptable cross-section of the transport volume, which expands from top to bottom, and a matching cross-section at the seal area to the filling device's inlet. The dosing device may incorporate various measuring elements, such as weighing scales or screw conveyors, to ensure accurate filling. The transfer control system utilizes sensor technology for real-time adjustments and can communicate with the tubular bag machine's control system. Furthermore, a discharge element, potentially utilizing compressed air, is included to facilitate the release of filling material from the transfer containers. The operational method emphasizes the timely opening of the seal before the transfer container halts in the dispensing station, enhancing the efficiency of the filling process.
