PURPOSE: To supply powder/grain roughly in a uniform state by providing a pipe type suction nozzle installed in a storage container free to vertically move and a suction nozzle vertical movement device to move this suction nozzle in the vertical direction. ;CONSTITUTION: A suction nozzle 9 and a nozzle of a suction device are connected to each other by a connecting pipe, and powder/grain 3 is stored in a storage container 5. When the nozzle is opened, air from a compressor is injected, simultaneously, the powder/grain 3 stored in the storage container 5 is sucked through the connecting pipe and the suction nozzle 9 by flow of this air and it is injected. At this time, the suction nozzle 9 is used while vertically moving it by some milimeters by a suction nozzle vertical movement device 13. It is possible to smoothly carry out suction of the powder/grain 3, to prevent blocking of the suction nozzle 9 with the powder/grain 3 and to prevent hardening of the powder/grain 3 at a portion adjacent to an opening part of the suction nozzle 9 by vertical movement of this suction nozzle 9.;COPYRIGHT: (C)1995,JPO
