Title:
CEILING TRANSPORT VEHICLE
Document Type and Number:
WIPO Patent Application WO/2015/053214
Kind Code:
A1
Abstract:
The purpose of the present invention is to achieve a ceiling transport vehicle that can appropriately detect an obstacle located below a raising/lowering body without increasing the size of the ceiling transport vehicle, even in cases where large articles are to be transported. An obstacle detection unit (S1) is fixed to a main body unit (21) at a position that is located above an article (B) supported by a raising/lowering body (30) located at a transporting position and that is located within the range of presence of the article (B) in a planar view, the obstacle detection unit being fixed in a state in which the radiation direction of detection light etc. is tilted toward the outside of the article (B). A control unit is configured such that, when the raising/lowering body (30) is raised/lowered between the transporting position and a transferring position (Pd), the presence/absence of an obstacle (W) is not determined on the basis of detection information of the obstacle detection unit (S1) while the raising/lowering body (30) is located within a target range, whereas the presence/absence of an obstacle (W) is determined while the raising/lowering body is not located within the target range. The range in which the detection light etc. of the obstacle detection unit (S1) acts so as to detect the article (B) supported by the raising/lowering body (30) is considered the detection action range, and the target range is set so as to include the detection action range.
