TRANSFERRING APPARATUS

摘要

PURPOSE: A transfer apparatus is provided to prevent damage to magnets without rotating an electromagnet unit, even if a rotary shaft is rotating at a high speed. CONSTITUTION: A transfer apparatus comprises a device frame(110), a plurality of rotary shafts(130), a plurality of permanent magnet units(140), an electromagnet unit(150) and a controller. A plurality of transferring rollers(120,122) is arranged on a plurality of rotary shafts. A plurality of rotary shafts can be rotated relatively and is combined in the device frame. A plurality of permanent magnet units is respectively combined in the end part of a plurality of rotary shafts. The electromagnet unit is separately placed to be near to a plurality of permanent magnet units. The magnetic force for rotating the rotary shaft generates between the electromagnet unit and a plurality of permanent magnet units. The controller controls the supply of the current applied to the electromagnet unit so that the rotary shaft can be rotated.
