FLOW DIVIDING DEVICE, CONTROL METHOD, FLOW DIVIDING METHOD AND PROGRAM, AND FLOW RATE CHARACTERISTIC MEASURING METHOD

摘要

PROBLEM TO BE SOLVED: To more surely divide a flow of powders and to convey the powders of the desired flow rate while reducing clogging more.SOLUTION: In the branch block 51, a conveyance path 71 and a conveyance path 72 with hollow cylindrical shapes for conveying conveyance air Aand powders, are formed. The conveyance path 72 branches from the conveyance path 71 at any angle between 15 degrees and 165 degrees. An ejector 52 is provided at the inlet of the conveyance path 71, and an ejector 53 is provided at the outlet of the conveyance path 72. A control device causes the ejector 52 and the ejector 53 to convey the conveyance air Atemporally exclusively, and when causing the ejector 52 to convey the powders, the control device changes a pressure of the conveyance air Aejected from the air ejection nozzle 84 of the ejector 52 so that a pressure measured by a pressure sensor 54 becomes a desired target value.SELECTED DRAWING: Figure 3
