In order to provide an air core coil fitting apparatus that can automatically fit an air core coil onto a core, an air core coil fitting apparatus includes a holding member, a coil fitting rod, a rod driving member, a pushing member, and a sending member. The holding member holds a core main body that is formed in a ring shape, has a gap extending through the core main body from an inner circumferential face to an outer circumferential face thereof, and allows an air core coil wound in advance to be fitted onto the core main body from one end thereof. On the coil fitting rod, the air core coil that is to be fitted onto the core main body held by the holding member is fitted. The rod driving member brings a front end of the coil fitting rod close to or into contact with the one end of the core main body held by the holding member. The pushing member pushes the air core coil fitted on the coil fitting rod, toward the one end of the core main body. The sending member is disposed at a circumferential edge of the core main body held by the holding member, and pulls the air core coil pushed by the pushing member and fitted onto the core main body, toward another end of the core main body.

2. Description of Related Art
FIG. 1 is a plan view showing a schematic configuration of an air core coil fitting apparatus according to an embodiment of the present invention.
FIG. 2 is a side view showing a schematic configuration of the air core coil fitting apparatus according to the embodiment of the present invention.
FIG. 3 is an enlarged plan view of an encircled portion 3 in FIG. 1, showing a state in which a core main body and an air core coil are attached.
Hereinafter, an air core coil fitting apparatus 10 according to an embodiment of the present invention will be described with reference to the drawings.
FIGS. 1 and 2 are a plan view and a side view showing a schematic configuration of the air core coil fitting apparatus 10. FIG. 3 is an enlarged plan view of an encircled portion 3 in FIG. 1, showing a state in which a core main body 70 and an air core coil 90 are attached. The air core coil fitting apparatus 10 is an apparatus in which the air core coil 90 wound in advance is fitted onto the core main body 70 having a gap 71 as shown in FIG. 3, after which a filling member 85 is fitted into the gap 71 (see FIG. 7).
As the overall configuration, as shown in FIGS. 1 to 3, the air core coil fitting apparatus 10 includes a holding member 20 adopted to hold the core main body 70, a coil fitting rod 26 on which the air core coil 90 is fitted, a rod driving member 30 adopted to bring a front end of the coil fitting rod 26 close to or into contact with the core main body 70, a pushing member 40 adopted to push the air core coil 90 toward the core main body 70, a sending member 50 adopted to pull the air core coil 90 onto the core main body 70, and a filling member fitting member 60 adopted to fit the filling member 85 into the gap 71. Note that, in FIG. 1, part of the configuration of the holding member 20 is not shown.
