摘要： A raising/lowering conveyance device for a container for conveying an article has container supports that can move toward or away from a container in the horizontal direction and up and down with respect to the container. The container supports have a plurality of container support pins that can advance/retreat in the horizontal direction from the container and that are forcibly held at a position protruding from a front surface of the container support. The container supports are configured to lift the container by the container support pins which protrude under a downward step surface formed on the outside of the container. A pin main body of the container support pins protrudes from the front surface and has a flat tip perpendicular to the center axis of the pin main body, and has a tapered shape that increases in diameter toward the flat tip and is thicker toward the end.

摘要： An article transport facility includes an article transport device capable of moving along a moving direction in movement sections. The movement sections include a transporting movement section and an out-of-the-way movement section. A work platform includes one or more out-of-trajectory portions located to at least one side along a lateral direction with respect to a mast trajectory, and one or more in-trajectory portions which are located in an area of the mast trajectory that excludes an area in which the mast is located when the article transport device is in the out-of-the-way stop position. Each of the one or more in-trajectory portions is configured to be capable of being moved to a support position located in the mast trajectory, and to an out-of-the-way position in which the in-trajectory portion is out of the mast trajectory along the lateral direction.

摘要： An article transport vehicle includes an obstacle sensor having a detection area that includes at least the width of the own vehicle and that expands in the advancing direction, controls the travel of the own vehicle, based on as front inter-object distance corresponding to own-vehicle position information indicating a position of the own vehicle and front object position information indicating a position on a track of a front object that is located in front of the own vehicle and whose position on the track is specified, and sets a length of the detection area E along the advancing direction of the obstacle sensor to be variable according to the front inter-object distance such that the length is less than the front inter-object distance.

摘要： In an overhead conveyance vehicle that travels along a rail serving as a conveyance track mounted on a ceiling and conveys a target magazine along the rail, when an elevating unit holding the magazine is hoisted or lowered between a conveyance position and a transfer position, a controller for controlling the operation of the overhead conveyance vehicle determines, based on an image captured by a camera, the presence or absence of an obstacle in an imaging range captured by the camera.

摘要： A facility comprises an inactive gas supplying device configured to supply inert gas to a container, a transport device configured to carry a container into, and out of, a storage section, a first controller configured to control the transport device, a second controller configured to control the inactive gas supplying device, and a third controller configured to transmit a first command to the first controller through a communications relay device, and to transmit a second command to the second controller Hp. The transport device receives electric power from the first electric power supply whereas the inactive gas supplying device, the second controller, the third controller, and the communications relay device receive electric power from one or more different-path electric power supplies each of which is different from the first electric power supply.

摘要： A support portion on which an object of paying of respects transported by the transport device is placed is provided at the support position. The support portion includes one or more restriction members configured to restrict movement of an object of paying of respects toward the first side by contacting the object of paying of respects from the first side, and one or more guide portions configured to move an object of paying of respects toward the first side to a contact position at which the object of paying of respects contacts the one or more restriction members or to a position located more toward the second side relative to the contact position. With one or more end portions, on the second side, of the bottom portion of the object of paying of respects being one or more end portions to be contacted, each of the one or more guide portions has a tilted guide surface that is tilted downward toward a first side end thereof with the tilted guide surface located in a position in which the one or more end portions, to be contacted, of the object of paying of respects that is being transferred from the transport device to be placed on the support portion, come into contact with the guide surface.

摘要： Conveying equipment includes carriages having a frame with front and rear ends coupled to adjacent carriages by vertical support shafts and having a floor board which is supported by the frame. A floor board main portion has a protruding arc-shaped end edge concentric with one of the vertical support shafts and a floor board sub-portion which has a recessed arc-shaped end edge concentric with the other vertical support shaft. The protruding arc-shaped end edge in one carriage and the recessed arc-shaped end edge in an adjacent carriage are relatively rotatable around the common vertical support shaft located at the arc centers of each of the edges. The floor board main portion overhangs from one end of the frame in each of the carriages and is supported on an overhanging portion which overhangs from the floor board sub-portion in the adjacent carriage so as to be freely relatively rotated.

摘要： Before a moving member that moves along a moving path stops, an article transport facility starts protrusion control by which a moving support portion that is provided on the moving member is moved so as to protrude toward a fixed support portion, and thereafter the article transport facility appropriately determines whether or not to continue the protrusion control. Upon the moving member reaching a protrusion start position, the protrusion control is started so that the moving support portion is moved to protrude, even if the moving member has not stopped. After the moving member has reached a position at which a detection unit that is fixed to the moving member can detect a detection target member that is provided on the fixed support portion, the execution of the protrusion control is continued as long as the detection unit is detecting the detection target member.
