PROBLEM TO BE SOLVED: To provide a combination balance that reduces damage to a body be measured and facilitates supply operation.SOLUTION: A combination balance comprises: a plurality of supply gates having a pair of gate plates for opening and closing a supply port; a plurality of measuring conveyors 1 provided below the gate plates; a weight sensor 2 for measuring the weight of a measurement object on the measuring conveyors 1; means 53 of determining whether a measured value of the weight sensor 2 is in a stable state; weight calculating means 52; means 58 of finding a combination of measuring conveyors 1 such that the total weight of the measurement objects is within a target weight range; means 54 of determining whether a measurement object has been supplied onto a measuring conveyor 1; and supply gate control means 56 of closing the gate plates when the measurement object has been supplied onto the measuring conveyor 1 and opening the gate plates when not. The supply gate control means 56 performs control to open the gate plates when it is not determined that the measured value is in a stable state within a predetermined time after it is determined that the measurement object has been supplied to the measuring conveyor 1.SELECTED DRAWING: Figure 5 |
