POWDER FEED SYSTEM

To feed alloy powder of predetermined weight to a vibration bowl feeder from a plurality of take-out ports to a pressing machine.SOLUTION: A powder feed system according to the present disclosure comprises: a vibration bowl feeder comprising a spiral conveyance truck for conveying powder via vibration, and a plurality of discharge openings provided on an outer peripheral surface; a plurality of powder weighing devices allocated to the plurality of discharge openings, respectively; a plurality of gate opening/closing devices that branch the powder conveyed by the vibration bowl feeder from above the conveyance truck and feed the powder to the respective powder weighing devices corresponding thereto from the plurality of gate opening/closing devices; and a control device for controlling the plurality of gate opening/closing devices and the plurality of powder weighing devices. The powder is fed to the plurality of powder weighing devices from the plurality of discharge openings, and the powder is fed to a pressing machine from the plurality of powder weighing devices, with a gate opening degree of each gate opening/closing device controlled by the control device based on weight of the powder measured by each powder weighing device.SELECTED DRAWING: Figure 1 【課題】振動ボウルフィーダに複数の取り出し口から所定重量の合金粉末をプレス機に供給する。【解決手段】本開示の粉末供給システムは、振動によって粉末を搬送する螺旋状の搬送トラックと、外周面に設けられた複数の排出開口部とを有する振動ボウルフィーダと、前記複数の排出開口部にそれぞれ割り当てられた複数の粉末計量装置と、振動ボウルフィーダによって搬送される前記粉末を前記搬送トラック上から分岐させて、複数の排出開口部から、対応する粉末計量装置に供給する複数のゲート開閉装置と、複数のゲート開閉装置および複数の粉末計量装置を制御する制御装置とを備える。各粉末計量装置によって計測される粉末の重量に基づいて各ゲート開閉装置におけるゲート開度を制御装置で制御することにより、複数の排出開口部から粉末を複数の粉末計量装置に供給し、粉末計量装置から粉末をプレス機に供給する。【選択図】図１
