<P>PROBLEM TO BE SOLVED: To provide a loader hopper capable of surely preventing powder and granular material from getting between a discharge port and an opening/closing member. <P>SOLUTION: In the loader hopper 3 for temporarily storing the powder and granular material to be pneumatically carried with pneumatic force generated by a suction blower, the discharge port 17 and a hopper discharge valve 14 are provided which discharges the stored powder and granular material and which opens/closes the discharge port 17, respectively. The hopper discharge valve 14 is stopped between an opening position and a closing position at a slightly opening position where the pneumatic force works, by a first air cylinder 15 and a second air cylinder 19. <P>COPYRIGHT: (C)2013,JPO&INPIT |
