Abstract
To provide a static eliminator and a static elimination system capable of strictly managing a manufacturing status of a product without increasing a management burden. The static eliminator includes an ion generation unit, an ion control unit, a measurement value acquisition unit, a data generation unit, and a nonvolatile storage unit. The ion generation unit generates ions. The ion control unit controls the ion generation unit. The measurement value acquisition unit acquires a measurement value related to control by the ion control unit and acquires a measurement time at which the measurement value has been acquired. The data generation unit generates history data based on the measurement value and the measurement time. The nonvolatile storage unit stores the history data.
Claims12
A static eliminator comprising:
- an ion generation unit that generates ions;
- an ion control unit that controls the ion generation unit;
- a static eliminator housing, in which the ion generation unit and the ion control unit are accommodated;
- a measurement value acquisition unit that acquires a measurement value related to the control by the ion control unit and acquires a measurement time at which the measurement value has been acquired;
- a data generation unit that generates history data based on the measurement value and the measurement time;
- and
- a nonvolatile storage unit that stores the history data, which is accommodated in the static eliminator housing.
A static eliminator comprising:
- an ion generation unit that generates ions;
- an ion control unit that controls the ion generation unit;
- a measurement value acquisition unit that acquires a measurement value related to the control by the ion control unit and acquires a measurement time at which the measurement value has been acquired;
- a data generation unit that generates history data based on the measurement value and the measurement time;
- a nonvolatile storage unit that stores the history data;
- and
- a fan that sends the ions generated by the ion generation unit in a predetermined direction,
- wherein the measurement value includes an amount of the ions and a rotational speed of the fan.
A static elimination system comprising:
- a static eliminator including
- an ion generation unit that generates ions,
