Abstract: A deviation amount is a difference between a first error that occurs when an article is placed on a first transfer destination by a first transport vehicle and a second error that occurs when the article is placed on a second transfer destination by the first transport vehicle. An nth error that occurs when the article is placed on an nth transfer destination other than the first transfer destination and the second transfer destination is acquired. In an mth transport vehicle other than the first transport vehicle, a stop position of an mth traveling body is corrected by the nth error and an mth-1 error occurring when the article is placed on the first reference platform, or by the nth error and an mth-2 error as well as the deviation amount, the mth-2 error occurring when the article is placed on the second reference platform.

Abstract: A conveyance vehicle system that achieves an increased efficiency of loading an article from a conveyance vehicle into a loading opening of an automated warehouse, includes a stocker, a conveyance vehicle, and a conveyance vehicle controller. The stocker includes racks, a loading port, and a stocker controller. The conveyance vehicle loads an article into the loading port of the stocker. The conveyance vehicle controller assigns the conveyance vehicle with an article conveyance command to convey the article to the stocker. The stocker controller receives a predicted conveyance command before the article is loaded from the conveyance vehicle into the stocker. The predicted conveyance command includes ID information of the article and information indicating whether or not the article is to be loaded into a rack.

Abstract: An automated warehouse system having an improved cycle efficiency of storing and retrieving articles to and from the automated warehouse system includes a storage station, a retrieval station, a plurality of article storage shelves, a stacker crane, and a system controller. An article is brought to the storage station to be stored and retrieved from the retrieval station. The article storage shelves store articles. The stacker crane can move an article between the storage station, the retrieval station, and the article storage shelves. The system controller keeps track of the amount of storage time articles have been stored and, when it determines that an article has been stored on an article storage shelf in a buffer area for a first predetermined amount of time or longer, the system controller controls the stacker crane such that the stacker crane carries the article from an article storage shelf in the buffer area to an article storage shelf in the first storage area.

Abstract: The present invention prevents an obstacle from entering a running route of an overhead carriage to allow the carriage to run smoothly, increasing carrying efficiency. The present invention provides a carrying system including a carriage 1 having a hoist 7 that elevates and lowers an article in a vertical direction and a running portion 2, and a track 12 which internally houses the running portion 2 and which is suspended from a ceiling. The carrying system has a cover 13 placed parallel to the track 12 to prevent entry of an obstacle into the track; the cover 13 is provided below the track 12 so as not to hinder the elevation and lowering of the article executed by the hoist 7.
