を発生させることにより、ブリッジの発生を防止させて
いた。Conventionally, when a powder bridge occurs on the inner wall surface of a powder tank, a worker breaks the bridge by poking it with a stick or the like, or hits the surface of the tank with a hammer or the like to generate vibration. , which prevented the occurrence of bridging.
然し乍°ら、粉体の計量システムにおいては、自動的に
作業を行なうために、作業員が上記のような作業を一々
行っていては、作業能率が極めて悪いと言う問題があっ
た。However, since the powder measuring system performs the work automatically, there is a problem in that the work efficiency is extremely poor if the operator performs the above-mentioned work one by one.
このため、最近では粉体タンクの内壁面にテフロン等を
