Abstract

PURPOSE:To provide a system enabling an efficient molding work by automating material selection in an injection molding work which is designed to convey molding material to a molding material retaining means selectively by a conveying means from one of a plurality of storage means according to a command. CONSTITUTION:When a command is given to convey material from any one of material hoppers 1-4, an electrostatic capacity type level gage 12 carried on a machine hopper detects whether the hopper section 11 is empty or not. When it is detected to be employ, after an idle blowing with a blower 8, an air damper 5 is opened to convey material from the hopper to a charge tank 7 which forces it to a cyclone section 10 with a blower 8 through a piping 14 until it is stored. When the level gage 12 detected that the hopper 11 is filled to the capacity, a stopping command is given to close the damper 5. After a continued idle blowing, the blower 8 is switched off.
