PROBLEM TO BE SOLVED: To provide a method for automatically supplying a resin raw material to a resin molding machine capable of remarkably lowering a defective fraction without mixing the material with dirt, dust or the like without exceeding a building area of a facility by alleviating a time and a labor hour required for a filling work of the material. SOLUTION: A vacant moving tank 7 of a resin raw material is sensed, and a moving tank conveyance command is sent to an unmanned conveying vehicle 8 to travel the vehicle 8 to a raw material supply station 4. Then, the vacant tank 7 is held at the vehicle 8, and traveled to a corresponding raw material filling station 6. Thereafter, the vacant tank 7 is mounted in the station 6, and the material is filled in the tank 7. The vehicle 8 is again traveled to the station 6, and the filled tank 7 is held at the vehicle 8. The vehicle 8 is traveled to the station 4, and the tank 7 filled in the station 4 is mounted on the vehicle 8. The vehicle 8 is traveled to the initial position, and waited until next moving tank conveying command is received. This series of steps are repeated.
