Title: Apparent specific gravity measuring method of powder during continuous feeding
Inventor: KUROSAWA TSUNEHITO
IPC: G01N9/00
Filed: 1993-03-12
Abstract: PURPOSE:To make the apparent specific gravity of powder accurately measurable in a good response manner by calculating the moving mean value of optimum frequency at this time, the last time, the before-last time or the like of an operational output signal obtainable at each one rotation of a feeder. CONSTITUTION:Powder weight W1-n as one rotation in a measuring feeder 2 from two digital load cell 3 and 4 is read (10) as binary coded decimal weight data via an amplifier 6 at each synchronizing pulse signal 9. A DELTAW detection circuit 11 inputted with these data detects a weight variation portion made up of subtracting the last value from this time value, nmaely, powder weight DELTAWn at each rotation with a weight signal Wn. In addition, a specific gravity computing circuit 13 secures the apparent specific gravity BD (=DELTAWn/DELTA) of feeding powder from a positive displacement flow rate DELTAV set (12) by this powder weight and a mold number. In succession, if moving means frequency m=3, by way of example, the means value moving-averaged with the specific gravity BD of this time, the last time and the before-last time is calculated (14). This value is indicated (15) as a signal showing the powder apparent specific gravity. Here, rotational frequency m is selected to the optimum value, whereby accurate measurement can be done accurately in terms of responsiveness.
