Title:
GRANULAR MATERIAL SUPPLYING DEVICE AND METHOD OF SUPPLYING GRANULAR MATERIAL
Document Type and Number:
Japanese Patent JP2020066475
Kind Code:
A
Abstract:
To provide a granular material supplying device and a method of supplying a granular material which are capable of improving measurement accuracy when a target measurement value is small while shortening a supply time when the target measurement value is large.SOLUTION: A granular material supply device 1, which is configured to supply a granular material toward a measuring container 7 installed on the lower side for obtaining a predetermined target measuring value, includes: a storage container 10 for storing the granular material; a valve body 21 provided in the storage container and opened when supplying the granular material; and a control unit 31 for controlling an opening/closing of the valve body. The control unit is configured to hold the valve body at in an open position until the detection value of a detection part 8 in the measuring container becomes a predetermined value lower than the target measurement value when the target measurement value exceeds the predetermined threshold value, and when the target measurement value is lower than the threshold value, the control unit opens the valve body in a pulsed manner so that the detection value of the detection part becomes the target measurement value.SELECTED DRAWING: Figure 1
