Embodiment Construction

[0022] Embodiments of the article transport facility will be described based on the drawings. Such as Figure 1 to Figure 3 As shown, the article conveying facility includes: a traveling rail 2 serving as a rail provided along a traveling path 1 , and an article conveying vehicle 3 that travels along the traveling path 1 on the traveling rail 2 to convey articles W. In addition, in the present embodiment, the article transport vehicle 3 transports a FOUP (Front Opening Unified Pod, Front Opening Unified Pod) accommodating semiconductor substrates as the article W.

[0023] Such as figure 1 As shown, the travel route 1 includes a circular main route 4 , a circular sub route 5 passing through a plurality of article processing units P, and a connecting route 6 connecting the main route 4 and the sub route 5 . Travel route 1 includes a plurality of sub routes 5 . The article transport vehicle 3 travels in the same circular direction (clockwise in this embodiment) on both the ma...

Abstract

An object of the present invention is to implement an article transport facility capable of appropriately traveling in a curved portion of a traveling path while suppressing an installation workload.An article transport facility (3) includes a rail (2) which includes at least one portion in which a travel path is curved, and an article transport vehicle (3) configured to travel along the rail totransport an article. The article transport vehicle (3) includes a guided portion (17) configured to be in contact with the rail (2) to be guided thereby, an obstacle detection sensor (21) configuredto detect an obstacle in a detection area (E) which is set to be located ahead of the article transport vehicle (3), and a setting portion configured to changeably set the detection area (E). The setting portion is configured to change the detection area (E) depending on an in-contact-rail shape which is a shape of the portion of the rail (2) that the guided portion (17) is in contact with.

Description

technical field [0001] The present invention relates to an article conveyance facility including a conveyance vehicle that travels along a rail that has a curved travel path at least in part. Background technique [0002] The article transport facility described in JP 2005-266936 A includes an obstacle sensor at the front end of the article transport vehicle. The obstacle sensor detects an obstacle present in a detection zone set forward from the obstacle sensor. When the object conveying vehicle detects an obstacle by the obstacle detection sensor, the conveying vehicle is stopped in an emergency to avoid contact between the conveying vehicle and the obstacle. [0003] In the above-described article conveyance facility, when the conveyance vehicle travels in a curved portion of the travel path that is curved, the detection area of ​​the obstacle detection sensor deviates largely in the path width direction relative to the travel path. For this reason, there are cases wher...
