Claims (1)
- 容器内の粉体を吸引するノズルと、
このノズルを粉体内に上方から出し入れするノズル送り手段と、
このノズルに接続され容器内の粉体を吸引しフィルタを介し分離して取出す吸引取出手段と、
吸引取出手段のフィルタ下流側の負圧力を検出する圧力センサと、
圧力センサの検出負圧力がフィルタ上流側の閉塞状態を示す予め設定した第1の負圧力にならないようにノズルの送りを制御する制御手段と、を備え、
制御手段は、圧力センサの検出負圧力に応じて、
(1)検出負圧力が前記の第1の負圧力に近づくまではノズルを下降させ、
(2)検出負圧力が第1の負圧力に近づいたときにはノズルを上昇させ、
(3)検出負圧力が減少し予め設定した第2の負圧力になったときにはノズルを下降させる、
ことを特徴とする粉体の空気輸送装置。
