Document Type and Number:
WIPO Patent Application WO/2019/035286
Kind Code:
A1
Abstract:
[Problem] The purpose of the present invention is to rotate an article by a prescribed angle or more so as to correspond to a transfer destination while decreasing the space inside a body part that houses the article and miniaturizing the body part and an overhead transport vehicle. [Solution] The present invention comprises: a traveling part 11; a body part 12; a transfer unit 13 that includes a holding part 15, a moving mechanism 16, and a rotation mechanism 19 and that delivers an article M from the transfer unit 13 to a transfer destination 30; and a control unit 14. The body part 12 has an inner wall 23a at a position contacted by the article M held by the holding part 15 when the holding part 15, which is at a storage position P1, is rotated by the rotation mechanism 19 by a prescribed angle θ. The control unit 14 causes the holding part 15 to travel using the traveling part 11 with the holding part 15 at the storage position P1, and when the article M is to be delivered, moves the holding part 15 to an extended position P2, P3 using the moving mechanism 16 and causes the article M to match a stipulated direction of the transfer destination 30 by causing the holding part 15 to rotate by the prescribed angle θ or more about a rotation axis AX using the rotation mechanism 19.
