Document Type and Number:
WIPO Patent Application WO/2022/102265
Kind Code:
A1
Abstract:
[Problem] To provide a traveling vehicle system capable of suppressing vibration of the traveling vehicle. [Solution] A traveling vehicle system may comprise a track and a traveling vehicle. The track may comprise a plurality of first tracks, a plurality of second tracks, and a partial track which is provided at a part where first and second extension lines intersect. The traveling vehicle may comprise a traveling part which travels on the upper side of the track, a main body part which is positioned below the track, and a coupling part which couples the traveling part and the main body part. Gaps through which the coupling part passes when the traveling vehicle travels may be formed between the first tracks and the partial track, and between the second tracks and the partial track. The traveling part may comprise four wheels which travel on the track, and a direction changing mechanism which changes the traveling direction of the traveling vehicle between a first direction and a second direction by rotating the four wheels around four respective rotation axes which are orthogonal to the respective axles of the wheels. In a planar view, a quadrilateral shape formed with the four rotation axes as the vertices thereof has sides any of which may be non-parallel to the first tracks and the second tracks.
