WIPO Patent Application WO/2021/090882
Kind Code:
A1
Abstract:
Provided is a feeding device which has a simple construction satisfying long-distance conveying, high-speed conveying, quietness, and high precision, and which does not require a high degree of assembly accuracy. This feeding device includes a rotating rotor 143 having, on an outer circumferential surface, a winding portion onto which a wire 151 is wound, and having, on an inner circumferential surface, a female screw 144, a supporting structure which rotatably supports a motor 121, a rotating shaft 132, a spline nut 134, and the rotating rotor 143, and a feed screw member 200 having a feed screw 201 which meshes with the female screw 144 of the rotating rotor 143, wherein the feed screw member 200 is supported by the supporting structure in such a way that the feed screw 201 meshes with the female screw 144 of the rotating rotor 143, and is configured in such a way that, when the rotating rotor 143 rotates once, the rotating rotor 143 is translated along the axis of rotation by an amount equivalent to the pitch of one winding of the wire 151.
