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.

Abstract: To appropriately control both long-term ion balance and short-term ion balance. A current flowing between an earth and a static eliminator via a ground electrode is detected, and feedback control is executed on a negative polarity high voltage power supply such that the current becomes a target current. Furthermore, a front wire mesh functioning as a detection electrode different from the ground electrode is arranged at a position where positive ions and negative ions generated by an electrode needle and an electrode needle arrive. Then, a current generated by the positive ions and the negative ions arriving at the front wire mesh is detected, and feedback control is executed on the negative polarity high voltage power supply such that the current becomes a target current.

Abstract: Provided is a static eliminator and a static elimination head which are capable of sufficiently eliminating static electricity irrespective of a surrounding environment thereof. Humidified air is generated by humidification of air by the humidified air generating part. The humidified air is allowed to flow out of an air flow outlet of a static elimination head. Further, one or a plurality of static elimination needles and a ground electrode are held in the static elimination head. A voltage for generating corona discharge is applied by a power supply device between the one or the plurality of static elimination needles and the ground electrode. The one or plurality of static elimination needles are arranged in the static elimination head such that ions generated by the corona discharge are sent out by the humidified air that is allowed to flow out of the air flow outlet.
