ABSTRACT:
In a powder coating material feeding apparatus, a lid section is mounted onto an opening of a metal drum containing powder coating material, and a support unit holds the metal drum in its upside-down or tilted position. An air distribution panel supplies carrier air into a conveying hose via a carrier air supply port, opens a pinch valve, activates a vibrator, and supplies fluidizing air into an air chamber in the lid section to fluidize the powder coating material in the metal drum. With this arrangement, the powder coating material is drained into the conveying hose through a drain port in the lower end of the metal drum in its upside-down position, and is then transferred to a powder tank by the carrier air.
