Title:
MAGNETIC BODY HOLDING DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/148321
Kind Code:
A1
Abstract:
A magnetic body holding device according to the present invention comprises: a first pole piece assembly comprising a first N-pole piece, a first S-pole piece, and a first permanent magnet; a second pole piece assembly comprising a second N-pole piece, a second S-pole piece, and a second permanent magnet; a third pole piece assembly comprising a third N-pole piece, a third S-pole piece, and a third permanent magnet; a fourth pole piece assembly comprising a fourth N-pole piece, a fourth S-pole piece, and a fourth permanent magnet; a coil wound around one or more of the first N-pole piece and the pole pieces; and a control device for controlling a current applied to the coil. Two or more of the first pole piece assembly, the second pole piece assembly, the third pole piece assembly, and the fourth pole piece assembly can move such that switching is possible between a first arrangement, in which the second pole piece assembly and the third pole piece assembly contact each other, the first pole piece assembly and the second pole piece assembly are spaced from each other, and the third pole piece assembly and the fourth pole piece assembly are spaced from each other, and a second arrangement, in which the first pole piece assembly and the second pole piece assembly contact each other, the third pole piece assembly and the fourth pole piece assembly contact each other, and the second pole piece assembly and the third pole piece assembly are spaced from each other. The control device controls a current, which is applied to the coil, thereby causing switching between the first arrangement and the second arrangement, and accordingly controlling the holding of the object to be attached and the release thereof.
