Abstract
A method for filling a container with a pyrotechnic charge using a filling system, said method including, when the powder is conveyed, a step of regulating the powder flow rate in which at least one powder conveyor device is brought to vibrate according to a vibration frequency control sequence, the vibration frequency being inversely proportional to the filling ratio of the container of the pyrotechnic charge.
Claims14
A filling method for filling a container of a pyrotechnic charge using a filling system, the filling system comprising at least:
- a reservoir for dispensing a pyrotechnic powder,
- a measuring device for measuring the pyrotechnic powder, and
- a powder conveyor device for conveying the pyrotechnic powder from the reservoir to a basin of the measuring device,
- wherein said filling method comprises:
- when the pyrotechnic powder is conveyed, a step of regulating the powder flow rate wherein the powder conveyor device is set in vibration according to a vibration frequency control sequence, the vibration frequency being inversely proportional to the filling ratio of the container of the pyrotechnic charge.
A filling system for filling a container of a pyrotechnic charge, comprising at least:
- a reservoir for dispensing a pyrotechnic powder,
- a measuring device for measuring the pyrotechnic powder, and
- a powder conveyor device for conveying the pyrotechnic powder from the reservoir to a basin of the measuring device,
- wherein the filling system comprises a vibrational actuator, coupled to the powder conveyor device for conveying the pyrotechnic powder,
- wherein the filling system further comprises a controller configured to implement a vibration frequency control sequence, the vibration frequency being inversely proportional to the filling ratio of the container of the pyrotechnic charge.
