WIPO Patent Application WO/2017/002810
Kind Code:
A1
Abstract:
This weighing apparatus (1) is provided with: hoppers (4, 6, 9) having gates (5, 8, 10) with each hopper configured to receive an object to be weighed from outside and, after letting the object stay temporarily, discharge the object through opening and closing of the corresponding gate; driving units (13, 14, 15) that cause the opening and closing of the gates; and a control unit (11) that controls each driving unit by varying a control signal to be outputted to the driving unit. The control unit detects whether a loss of synchronization has occurred during the opening or closing of the gate with respect to each driving unit, and varies the control signal to be outputted to the driving unit depending on whether a loss of synchronization has been detected.
