<p><P>PROBLEM TO BE SOLVED: To provide a combination weigher capable of improving accuracy in combination, suppressing an increase in manufacturing cost, and achieving compactification. <P>SOLUTION: A combination weigher comprises a plurality of weighing units Cw, each of which includes: a weighing conveyor 1 that temporarily holds weighed objects being fed and that can transport the held weighed objects to two directions opposite to each other; a weight sensor 2 that weighs the weighed objects on the weighing conveyor 1; and two standby conveyors 3a, 3b that are arranged on both ends of the weighing conveyor 1, that hold respective weighed objects fed from the weighing conveyor 1 in different positions and that can transport the held weighted objects to two directions opposite to each other. The combination weigher also comprises a control unit 5 for causing the standby conveyors 3a, 3b to perform transportation so as to discharge only weighed objects selected for a discharge combination after the discharge combination, composed of weighed objects whose total weight is within a target weight range, is obtained from among the weighed objects held by the standby conveyors 3a, 3b. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
