Abstract: The object is to provide a vehicle system capable of suppressing a decrease in article transport efficiency while ensuring a route of an operator. The vehicle system includes a grid-patterned rail, a vehicle traveling on the rail, a controller that controls the vehicle, a work terminal that transmits identification information indicating an actual location to the controller, and a scaffold for allowing an operator carrying the work terminal to walk below the rail, the scaffold being provided below the rail. If entry permission to one or more cells formed by the rail is obtained from the controller, the vehicle enters the one or more cells. If entry permission to the one or more cells is not obtained from the controller, the vehicle does not enter the one or more cells.

Abstract: A ceiling conveyance vehicle includes a traveling wheel to roll on a track including a first track and a second track and a main body below the track and coupled to the traveling wheel. The ceiling conveyance vehicle includes a direction changer to change between a first state in which the traveling wheel rolls on the first track and a second state in which the traveling wheel rolls on the second track, with an orientation of the main body with respect to the track maintained, an article holder capable of holding an article, a hoisting-and-lowering driver to hoist and lower the article holder, a lateral slider to slidingly move the hoisting-and-lowering driver in a horizontal, linear direction, and a first rotational driver to rotationally drive the lateral slider around a first perpendicular axis with respect to the main body.

Abstract: A traveling vehicle system includes a track and a ceiling traveling vehicle. The track includes a first track, a second track, and a connection track. The ceiling traveling vehicle includes a direction changer that turns a coupler, which couples a traveling wheel and a main body to each other and passes through a gap D-between the first track or the second track and the connection track. A guider is provided in the coupler, moves along a first guide surface in a first state in which the traveling wheel rolls on the first track, and moves along a second guide surface in a second state in which the traveling wheel rolls on the second track.

Abstract: A ceiling traveling vehicle includes a traveler to travel along a grid-shaped track, a main body coupled to the traveler and below the track, and a detector on a rear side of a center of the main body in a traveling direction of the traveler and below the main body to apply detection light forward in the traveling direction and downward and receive reflected light of the detection light to detect an obstacle.

Abstract: An article relay apparatus is located on an outside wall separating an interior and an exterior of a stocker and relays an article between the interior and an operator. The article relay apparatus includes an opening that faces and is open to an operator passage outside the outside wall, a placement table in a rear side in a depth direction of the opening and on which the article is to be placed, a first cover above the opening and on a front side in the depth direction of the opening, the first cover defining a portion of the outside wall, and a second cover that is located between the first cover and the opening, defines a portion of the outside wall, and has a shape extending downwardly toward a rear side in the depth direction.

Abstract: A traveling vehicle system includes a track including a first gap, a partial track, and a second gap, a traveling vehicle including a drive wheel and first and second auxiliary wheels, a first auxiliary track on a near side of the first gap in a traveling direction and in contact with a lower end of the first auxiliary wheel while a lower end of the drive wheel passes through the first gap when the drive wheel enters the partial track, and a second auxiliary track on a far side of the second gap in the traveling direction and in contact with a lower end of the second auxiliary wheel while the lower end of the drive wheel passes through the second gap when the drive wheel leaves the partial track.

Abstract: A retrieving device 1 includes: a supporting unit 13 configured to support a front portion of the load 120 from a front side of the load 120; a coupling unit 9, 11 configured to be coupled, via a coupling member 142, to a moving device 140 being capable of moving the supporting unit 13 in an up-and-down direction; and a gripping unit 15, 17 provided on a side opposite to the supporting unit 13 with the coupling unit 9, 11 interposed therebetween.

Abstract: A supporting device includes a supporting member including a first positioning member positioning a bottom of a first article and inhibiting horizontal movement of the first article, and a second positioning member positioning a bottom of a second article and inhibiting horizontal movement of the second article. The first and second positioning members release the articles when elevated. The supporting device includes a first anti-drop member preventing the first article from being elevated and released and a second anti-drop member preventing the second article from being elevated and released. The first positioning member is higher than the second positioning member. The end of the first article closer to the first and second anti-drop members is nearer or equally distant to the first and second anti-drop members than a corresponding end of the second article. The second anti-drop member is retracted from the end of the first article when the first positioning member positions the first article.
