<P>PROBLEM TO BE SOLVED: To prevent false weight measurement that is caused by delay in filling timing of a weighed object into a weighing hopper. <P>SOLUTION: A weighed object 20b resting in an unstable state at a conveying end of a linear feeder pan 6 undesirably drops due to vibration or the like associated with opening of a discharge gate 12a of a supply hopper 12 when a weighed object 20a in the supply hopper 12 is caused to drop and discharge to a weighing hopper 13, and it is determined, based on a detection output of a weighed object sensor 7 for detecting the weighed object 20b at the conveying end of the linear feeder pan 6 and opening/closing timing of the discharge gate 12a of the supply hopper 12, that whether or not the weighed object 20b has been later filled into the weighing hopper 13 through the supply hopper 12 whose discharge gate is opened. A weighed value after a lapse of an extended stable time is regarded as a weight of a weighed object for the weighing hopper 13 that is determined to have been later filled. <P>COPYRIGHT: (C)2012,JPO&INPIT |
