Abstract: A traveling vehicle system includes: a plurality of traveling vehicles; and a controller that is capable of communicating with the plurality of traveling vehicles and that controls the plurality of traveling vehicles, a traveling region of the traveling vehicles having designated therein a plurality of blocking sections each of which undergoes, when occupied by one of the plurality of traveling vehicles, exclusive control to prohibit another traveling vehicle from moving thereinto. The controller determines, where in a series of operations to be executed by the traveling vehicle, the operation of the traveling vehicle from the start of traveling to stopping before executing a predetermined operation included in the series of operations is demarcated, whether or not to grant the traveling vehicle an occupation permission for the blocking sections to be occupied for the traveling vehicle to execute operations.

Abstract: A transport system includes transport vehicles to travel along a track and transport a load, and a controller. The track includes a first main track and branch tracks connecting to the first main track via different confluence points. The controller is configured or programmed to execute departure control that causes the transport vehicles stopped at respective stop positions of the branch tracks to depart toward the first main track for each of the branch tracks. The departure control prohibits, in accordance with whether the transport vehicle is present in a certain section on the track, departure of at least one of the transport vehicles stopped at the respective stop positions of the branch tracks.

Abstract: A transport system includes a plurality of transport vehicles and a controller. The transport vehicle includes a travel unit and transfer unit. The controller performs a blocking control to prohibit transport vehicles other than the transport vehicle from entering a blocking zone corresponding to the area occupied by the transport vehicle when transferring an article in a plan view. To transfer an article from/to a placement table, the transport vehicle travels along the route to the placement table in a first direction. An area of the blocking zone when the transport vehicle accesses to the placement table in the first direction is equal to or less than an area of the blocking zone identified when the transport vehicle accesses to the placement table in the second direction different from the first direction.

Abstract: A transport system includes transport vehicles, and a controller to control traveling of the transport vehicles. The track includes a first main track, junction points on the first main track and spaced apart from each other, and branch tracks each connected to the first main track via the junction points different from one another. The junction points are spaced apart from each other on the first main track. On each of the branch tracks, a stop position corresponding to a delivery port for each transport vehicle to deliver and receive a load is provided. The controller controls the respective transport vehicles stopping at the stop positions of the branch tracks to control a transport vehicle on a downstream branch track to start simultaneously with or before a transport vehicle on an upstream branch track.

Abstract: A traveling vehicle system includes a plurality of traveling vehicles, a controller that controls the plurality of transport vehicles, a traveling region of the traveling vehicles having a plurality of blocking sections each of which undergoes exclusive control to prohibit another traveling vehicle from moving thereinto. The traveling vehicle makes a request to the controller for occupation permissions regarding a plurality of blocking sections to be occupied by the traveling vehicle and are designated by instructions. The controller then determines, among the plurality of blocking sections for which the traveling vehicle makes a request for occupation permissions, one or more of the blocking sections that are able to allow permissions consecutively from an end thereof to be primarily occupied, based on the traveling direction of the traveling vehicle, and the controller grants the traveling vehicle the permissions for one or more blocking sections determined to allow the permissions.

Abstract: A controller determines, when a traveling vehicle to proceed in a first direction from a predetermined cell toward a destination is present, whether or not to grant the traveling vehicle occupation permission for a cell adjacent to the predetermined cell in the first direction. The traveling vehicle proceeds in the first direction if occupation permission for the adjacent cell has been granted from the controller, whereas the traveling vehicle stops at the predetermined cell if occupation permission has not been granted. The controller assigns to the traveling vehicle a traveling instruction in which a cell situated at a plurality of cells ahead of the predetermined cell in the second direction is designated as a waypoint to the destination if the traveling vehicle has not obtained occupation permission for the adjacent cell and has continuously been in a stop state at the predetermined cell for a predetermined period of time.

The track includes a first main track, junction points on the first main track and spaced apart from each other, and branch tracks each connected to the first main track via the junction points different from one another. The junction points are spaced apart from each other on the first main track. On each of the branch tracks, a stop position corresponding to a delivery port for each transport vehicle to deliver and receive a load is provided. The controller controls the respective transport vehicles stopping at the stop positions of the branch tracks to control a transport vehicle on a downstream branch track to start simultaneously with or before a transport vehicle on an upstream branch track.
