Key facts

• Dosing accuracy: ± 2 mg for two powder types
• Cycle time: 7 s per dosing / 1.75 s per detonator
• Safety concept with pressure container & protective personnel
• Integration into existing workpiece carrier system

Task

Two explosives in the milligram range must be precisely dosed and layered for the filling of airbag detonators. The required process times are highly synchronized: 8 seconds per dosing, 2 seconds per detonator. Powder handling is carried out under the highest safety precautions by trained personnel. The system must be integrated into an existing workpiece carrier system.

Solution

Two filling systems, each with two dosing stations, ensure precise and reliable powder processing. Dosing takes place via spiral conveyors and weighing modules in specially developed safety containers. The refiller enables safe powder feeding by the personnel. YZ axis systems and a conveyor belt guarantee efficient workpiece transportation within the overall system.
