Abstract: In a transport system, a local track is disposed so as to be below an overhead travelling vehicle track in parallel or substantially in parallel therewith, and furthermore above a loading port of a processing device from upstream of the loading port to downstream of the loading port. A local vehicle including a hoist travels along the local track. Below the local track, a first buffer is disposed upstream of the loading port of the processing device, and a second buffer is disposed downstream of the loading port of the processing device, and the overhead travelling vehicle and the local vehicle can both perform delivery and receipt of the article with the first buffer and the second buffer.

Abstract: An overhead traveling vehicle includes a hoist and a first sensor that monitors obstacles below, and a local carriage includes a hoist and travels along the track. A buffer is suspended from the track by vertical supports that extend vertically downward, and no members of the buffer are provided directly over load ports. A second sensor, which monitors an obstacle in a vicinity of the load ports and in a passageway-side area on a side opposite to a processing device, is provided on the track and transmits an obstacle detection signal to the overhead traveling vehicle and the local carriage. Upon receiving the obstacle detection signal from the second sensor, the overhead traveling vehicle and the local carriage stop the hoists, and the overhead traveling vehicle does not monitor obstacles in the passageway-side area using the first sensor.

Abstract: In a transport system, a track for a local carriage is provided directly below a track for overhead traveling vehicles, and the overhead traveling vehicles and the local carriage both transfer an article to and from the same transfer destination. A buffer is connected to the track for the transport local carriage to deliver and receive the article to and from the local carriage and includes a transport in/out cell below the track for the overhead traveling vehicles to deliver and receive the article to and from the overhead traveling vehicles, the buffer being provided in a location not directly below the track of the local carriage.

Abstract: A system for transporting an article between a plurality of processing devices includes a track extending above load ports of the processing devices, and an overhead travelling vehicle that travels along the track and has a hoist. A local track disposed lower than the track extends at least to a position under the track, and is oriented perpendicular to the track when viewed from above. A local carriage travels along the local track and has a hoist for vertically moving the article. A buffer disposed below the local track delivers and receives the article to and from the local carriage, and extends at least to a position under the track.

Abstract: An overhead traveling vehicle and the local carriage each includes a hoist and travel directly over load ports. The track for the local carriage includes a pair of rails directly under a track for the overhead traveling vehicle, and articles vertically pass between the pair of rails using the hoist of the overhead traveling vehicle. A sensor detects an article that is horizontally swinging in a direction perpendicular or substantially perpendicular to the lengthwise direction of the track for the local carriage in the horizontal plane and is provided at least at a position that is under the track for the local carriage and outside of the raising and lowering path of an article that is not horizontally swinging. The overhead traveling vehicle and the local carriage stop the raising and lowering of the hoists when the sensor detects an article that is horizontally swinging.

Abstract: A transport system includes a first track that passes above loading ports of the processing devices, and an overhead travelling vehicle that travels along the first track and includes a hoist. A second track is below the first track, passes above the loading ports, and is disposed in parallel or substantially in parallel with the first track. A buffer is provided below the second track at a position higher than the loading ports, and is arranged such that the articles can pass in a vertical direction over the loading ports. The buffer is disposed such that the articles can pass through the height position of the buffer in a vertical direction over the loading ports. A local vehicle travels along the second track and includes a hoist to perform delivery and receipt of the articles between the buffer and the loading ports.
