  • Patent number: 11460338
    Abstract: [Problem] To provide a combination weighing apparatus that reduces power consumption during opening and closing operations of a hopper gate. [Solution] In a combination weighing apparatus 1, a control unit 70 controls a stepping motor 60 via a control signal that is input to the stepping motor 60. The control signal that is input to the stepping motor 60 is a voltage value corresponding to a desired current value. The control unit changes the control signal to the stepping motor 60 in conjunction with a change in the settings of the opening and closing speed of the gate 20. As a result, it becomes possible to supply power needed for the operation of the gate 20, and power can be saved.
