  • Patent number: 10699925
    Abstract: Regarding a transfer system that includes a plurality of transfer vehicles that transfer articles, the present invention realizes technology that can alleviate congestion that is caused due to the travel speed of a specific vehicle that performs a specific task being lower than that of the transfer vehicles. The transfer system includes a plurality of transfer vehicles that travel on a transfer path to transfer articles, and the transfer system further includes: a specific vehicle that performs a specific task while travelling on the transfer path at a speed lower than that of the transfer vehicles; and a congestion determination unit that determines whether or not there is congestion behind the specific vehicle. Upon the congestion determination unit determining that there is congestion, the specific vehicle suspends the task and performs evacuation travel to evacuate from a task point at which the specific vehicle was performing the task.

  • Patent number: 10604351
    Abstract: A travelling path includes a first path and a second path that branches off from or merges with the first path at a connection position of the first path. A management area and a check area are provided for the first path. The management area includes a section from the connection position to a position that is at a first preset distance upstream of the connection position, and a section from the connection position to a position that is at a second preset distance downstream of the connection position. The check area includes a section from a preset position to a position that is at a fourth preset distance upstream of the preset position. In a state where an article transport vehicle that includes a control unit is located in the check area, the control unit determines whether or not the article transport vehicle is in a leading state where no other article transport vehicle is present forward of the article transport vehicle in the check area.

  • Patent number: 8942844
    Abstract: An article storage facility includes a transport device for transporting the transporting containers to the plurality of storage units, a controller, and a supply state detecting device for detecting a supply state of the inactive gas to the plurality of storage units. The controller makes a determination based on detected information from the supply state detecting device as to whether the inactive gas is properly supplied, and manages the plurality of storage units by distinguishing the disallowed storage units for which it is determined that the inactive gas is not properly supplied from the allowed storage units that are the storage units that are not the disallowed storage units. The controller performs a retreating transport operation in which a transporting container, that is stored in the storage unit that is changed from the allowed storage unit to the disallowed storage unit, is transported to an allowed storage unit.
