  • Patent number: 10239541
    Abstract: An article transport vehicle includes a travel member capable of traveling along a travel path, a support member located below the travel member for supporting an article, and a connecting member which connects the travel member and the support member to each other. The connecting member includes a travel member side connecting portion connected to the travel member, a support member side connecting portion connected to the support member, and an elastic member which is elastically deformable. The travel member side connecting portion and the support member side connecting portion are connected to each other for relative movement along the vertical direction. An elastic member is interposed between the travel member side connecting portion and the support member side connecting portion.

  • Publication number: 20190016574
    Abstract: An object is to provide an article transport vehicle which includes one or more fall preventing members while reducing any increase in complexity of the arrangement. An article transport vehicle includes a travel portion, a support portion, and a moving mechanism. The moving mechanism is configured to move the support portion to a projected position and to a retracted position. The support portion includes a support member configured to support a container, a movable member configured to be moved along a lateral width direction by the moving mechanism, and a vertically moving mechanism configured to move the support member along the vertical direction with respect to the movable member. The article transport vehicle further includes one or more fall preventing members configured to prevent a lid of a supported container from falling, and a movement coupling mechanism configured to move the one or more fall preventing members when the support member is moved.

  • Patent number: 10083847
    Abstract: A ceiling transport vehicle includes an obstacle detecting portion fixed to a main body portion at a location that is above an article supported by a vertically movable member located at a transport purpose position. The obstacle detection portion is within an area in which the article exists in plan view such that a direction in which detection light, etc., is emitted is tilted outward of the article. When vertically moving the vertically movable member between the transport purpose position and the transfer purpose position, the controller is configured not to determine presence of an obstacle based on detected information from the obstacle detecting portion while the vertically movable member is located in a subject range, and is configured to determine presence of an obstacle while it is not located in the subject range.

  • Patent number: 9938120
    Abstract: The distance between a pair of fall prevention members can be adjusted by causing the pair of fall prevention members to be linearly moved in mutually opposite directions along the spaced-apart direction along which the pair of fall prevention members are spaced apart from each other. A distance adjustment actuator portion is configured to be able to adjust the distance between the pair of fall prevention members to any of a distance for retraction greater than a width of a larger transported object in the spaced-apart direction; a distance for the larger transported object which is less than the distance for retraction and which corresponds to the width of the larger transported object in the spaced-apart direction; and a distance for the smaller transported object which is less than the distance for the larger transported object and which corresponds to a width of the smaller transported object in the spaced-apart direction.

  • Patent number: 9576832
    Abstract: An article transport vehicle is provided in which it is difficult for the transported article support portions to interfere with the supported portion of the transported article while reducing transmission of vibrations to the transported article, during a travel of the travel member or during a vertical movement of the vertically movable portion. A support unit which is vertically moved relative to a travel member is provided with a guiding supporting portion for guiding and supporting transported article support portions for supporting a supported portion of a transported article such that the transported article support portions can be moved to support positions and to retracted positions, and a damper element which is located between a vertically movable portion and the guiding supporting portion and receives load from the guiding supporting portion and which is elastically deformable in a vertical direction.

  • Publication number: 20160240417
    Abstract: A ceiling transport vehicle is provided in which any obstacle located below a vertically movable member can be detected properly while reducing any increase in the size of the ceiling transport vehicle even when transporting large articles. An obstacle detecting portion is fixed to a main body portion at a location that is above an article supported by a vertically movable member located at a transport purpose position, and that is within an area in which the article exists in plan view such that a direction in which detection light, etc., is emitted is tilted outward of the article. When vertically moving the vertically movable member between the transport purpose position and the transfer purpose position, the controller is configured not to determine presence of an obstacle based on detected information from the obstacle detecting portion while the vertically movable member is located in a subject range, and is configured to determine presence of an obstacle while it is not located in the subject range.
