ABSTRACT:
A powder supply system including a powder replenishment device as a powder source, a suction device and a plurality of powder supply units connected in series. Each of the powder supply units sprinkles powders toward an object mounted on each processing device. An upstream end powder supply unit is fluidly connected to the powder replenishment device, and a downstream end powder supply unit is fluidly connected to the suction device. A suction force generated by the suction device sucks powders from the powder replenishment device through the powder supply units, and powders are successively accumulated in the powder supply units in the order from the upstream end powder supply unit to the downstream end powder supply unit. A powder sensor is provided between the rearmost powder supply unit and the suction device. If all powder supply units are filled with powders, residual powders are discharged out of the downstream end powder supply unit. If the sensor detects the powder, operation of the suction device and the powder replenishment device is stopped.
