To provide a doffing device for an automatic winder capable of quickly eliminating static electricity generated in a winding part of all winding units even if kind of yarn and environment are changed.

This doffing device 1 to be reciprocated between a plurality of winding units is provided with an electric potential sensor 3 for measuring electrostatic potential, an ion generation control section 4, and an ion generating and injecting section 5. An electricity eliminating means 2 is arranged to eliminate static electricity by selecting an ion having a polarity opposite to the measured electrostatic potential and injecting the selected ion.
