Abstract:
1. A transport system, comprising: a first load port and a second load port each including a loading surface arranged to allow an article to be loaded onto the loading surface from above the loading surface, the article including a positioning hole located in an undersurface of the article; and a transport device arranged to lower the article to the first load port and the second load port; wherein a positioning protrusion corresponding to the positioning hole is provided on the loading surface of the first load port; the transport device is arranged to align the positioning hole with the positioning protrusion when lowering the article to the first load port; the transport device is a transport vehicle travelling along a track that passes above the first load port; the second load port is arranged at a side of the track; the transport vehicle includes a hoist mechanism configured to suspend a gripping mechanism, and a horizontal position adjusting mechanism configured to adjust a horizontal position of the hoist mechanism; the transport device is configured to tilt the undersurface of the article with respect to a horizontal direction before placing the article onto the second load port; and the loading surface of the second load port is tilted with respect to the horizontal direction such that an angle between the loading surface of the second load port and the undersurface of the article before the article is placed onto the second load port is smaller than an angle between the undersurface and the horizontal direction.
