POWDER SUPPLY DEVICE AND POWDER SUPPLY METHOD

PROBLEM TO BE SOLVED: To provide a powder supply device for supplying powder to a container, which can supply powder simply even in the case of a container having a big opening portion formed thereon without being limited to a special container and prevents the powder from leaking to the outside of the container.SOLUTION: A powder supply device 1 comprises: a powder supply pipe 2 which has a discharge port 10 for discharging powder to a container formed thereon; a supply portion 3 which supplies the powder from a supply port 16 which is located above the discharge port 10 and opens in the powder supply pipe 2; and a negative pressure device 4 which sucks air in the powder supply pipe 2 from a suction port 17 which is located above the supply port 16 and opens in the powder supply pipe 2.SELECTED DRAWING: Figure 1 【課題】容器に粉体を供給する粉体供給装置において、特殊な容器に限られず、大きな開口部が形成された容器であっても粉体を簡単に供給することができると共に、粉体が容器外部に漏れることが抑制された粉体供給装置を提供する。【解決手段】粉体供給装置１は、容器に粉体を排出する排出口１０が形成された粉体供給パイプ２と、排出口１０よりも上方に位置すると共に粉体供給パイプ２内に開口する供給口１６から、粉体を供給する供給部３と、供給口１６よりも上方に位置すると共に粉体供給パイプ２内に開口する吸引口１７から、粉体供給パイプ２内の気体を吸引する負圧装置４とを備える。【選択図】図１
