摘要： A transport system includes a track, transport vehicles, an area controller, buffers, and a host controller. The area controller, when a number of the transport vehicles present within a control area is a predetermined number and when receiving a first transport command to convey an article from a transfer port to a transport destination outside the control area from the host controller, stores the first transport command and transmits a report that the first transport command is not able to be assigned to the transport vehicle to the host controller. The host controller, when receiving the report, when the buffer is present, transmits a command to delete the stored first transport command to the area controller, generates a second transport command to convey the article from the transfer port to the buffer, and transmits the second transport command to the area controller.

摘要： A transport system includes: an image capturer included in a transport vehicle; a positional deviation detector that detects a positional deviation between a pre-correction position at a time when the article is placed on a reference transfer destination and a reference placement position; a corresponding relationship calculator that finds a pixel deviation between a pre-correction image and a post-correction image and calculates an actual deviation amount per unit pixel, the pre-correction image being captured at an initial position of the transport vehicle by the image capturer, and the post-correction image being captured by the image capturer at a position of the transport vehicle deviated by the positional deviation; and the correction amount calculator that finds a pixel deviation between the post-correction image and a transfer destination image captured of another transfer destination and calculates a correction amount from the pixel deviation and the actual deviation amount per unit pixel.

摘要： A travelling vehicle system that allows smooth travelling of a priority travelling vehicle includes travelling vehicles that travel along a route and a host controller that controls the travelling vehicles. The host controller includes a priority travelling vehicle transmitter that selects a priority travelling vehicle among the travelling vehicles, a passage command transmitter that transmits a passage command to a normal travelling vehicle to pass through a point in a predetermined range on the route which the priority travelling vehicle is scheduled to pass through, the normal travelling vehicle having a stop command to schedule to stop at the point, and a cancel command transmitter that transmits a cancel command to the normal travelling vehicle to cancel the given passage command when the priority travelling vehicle passes through the point. The normal travelling vehicle stops at the point in accordance with the stop command of the normal travelling vehicle, when the normal travelling vehicle receives the cancel command from the cancel command transmitter.

摘要： 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.

摘要： A track in a transport system includes a standby section associated with a certain processing apparatus to allow a transport vehicle to wait. When determining a transport request to transport a FOUP to a load port of the certain processing apparatus exists, the controller allocates, to the transport vehicle, a first transport command to transport the FOUP to the standby section. When reaching the standby section, the transport vehicle waits while holding the FOUP. Subsequently, when determining that the FOUP is transportable to the load port of the certain processing apparatus, the controller allocates, to the transport vehicle, a second transport command to transport the FOUP to the load port of the certain processing apparatus.

摘要： A transport system includes a track, overhead transport vehicles, and a controller. The controller provides a traveling command to travel to a destination point, to a first overhead transport vehicle that is able to receive a transport command to acquire a FOUP from a station and that is less than a first distance from the station. When a second of the overhead transport vehicles that is able to receive the transport command and is less than the first distance from the station, is detected before providing the transport command to the overhead first transport vehicle, the controller provides the traveling command to the second overhead transport vehicle. Then, the controller provides the transport command to the one of the first and second overhead transport vehicles that first passes through the destination point.

摘要： A travelling vehicle system additionally sets a waiting point such that a number of waiting points is equal to a number of empty travelling vehicles present on a travelling route upon detection of an empty travelling vehicle. The system searches a route from a start point to an end point when the additionally set one waiting point is taken as the start point and a position of one empty travelling vehicle is taken as the end point, the one empty travelling vehicle being detected by a detection portion and not waiting at the waiting point. The system allocates to the other empty travelling vehicle the travelling command to move to the one waiting point and allocates to the one empty travelling vehicle the travelling command to move to the other waiting point which becomes empty by movement of the other empty travelling vehicle.

摘要： A transport vehicle system includes a track, transport vehicles, placement units to deliver or receive articles, and area controllers that each receive a conveyance instruction from a host controller and control a transport vehicle in a jurisdiction area to execute various instructions. The area controller, in response to receiving from the host controller a conveyance instruction destined for one special placement unit belonging to a jurisdiction area, transmits to another area controller a movement instruction to control an empty transport vehicle to move toward the jurisdiction area, and also controls an empty transport vehicle that has become available in the jurisdiction area after transmission of the movement instruction to execute the conveyance instruction.
