Abstract: An article transport vehicle includes a transport vehicle main body, a first travel portion, a second travel portion, and power-receiving portions for receiving driving electric power without contact from one or more electricity supply lines. The first travel portion rotatably supports a transport vehicle main body. The second travel portion rotatably supports the transport vehicle main body. The power-receiving portions include a first power-receiving portion which is configured to be rotated integrally with the first travel portion, and a second power-receiving portion which is configured to be rotated integrally with the second travel portion.

Abstract: The linearly moving and rotating device includes a support portion that supports an operated member integrally provided with the article support portion, for rotation about the movable axis and for movement along the first direction, and a linearly movable member which is moved along the first direction by the actuator. The operated member is connected to the linearly movable member in a portion spaced apart from the movable axis as seen along a direction along the movable axis. The linearly moving and rotating device includes an operating state switching portion which can be switched to a linearly moving state for restricting rotation of the operated member about the movable axis and for allowing movement of the operated member along the first direction, and to a rotating state for allowing rotation of the operated member about the movable axis and for restricting movement of the operated member along the first direction.

Abstract: A ceiling guided vehicle includes a travel driving portion, an elevation driving portion, and a control portion that controls the operation of the travel driving portion and the elevation driving portion. An auxiliary unit that supplies, to the ceiling guided vehicle, one or both of power for driving the travel driving portion and the elevation driving portion and a control signal is provided so as to be attachable to and removable from the ceiling guided vehicle. The auxiliary unit includes a supported portion configured to be supported in a suspended state on a supporting portion provided on the ceiling guided vehicle; and an abutment portion configured to abut against the ceiling guided vehicle in a plurality of abutment areas disposed at different positions in plan view, and the abutment areas are provided at positions lower than the supporting portion in a vertical direction.

Abstract: Each of a pair of support members includes a lightweight-article support portion that is inserted into an insertion space of a lightweight article and supports a support-target portion of the lightweight article from below and a heavyweight-article support portion that is inserted into an insertion space of a heavyweight article and supports a support-target portion of the heavyweight article from below. The heavyweight-article support portion is formed to be thick in the vertical direction compared with the lightweight-article support portion. The lightweight-article support portion is provided at a position that is located in the insertion space of the heavyweight article when the heavyweight-article support portion is inserted into the insertion space of the heavyweight article, and formed integrally with the heavyweight-article support portion.

Abstract: Object is to provide a travel facility in which a travel member, that became incapable of traveling due to a cause other than a power supply failure, can be moved to another location on a travel path. A second travel member, provided separately from the first travel member, includes an external signal generating portion for generating an external travel control signal to be sent to a first travel actuator and a connecting portion which can transmit the external travel control signal. The first travel member includes a first connecting portion which can receive the external travel control signal and can transmit the external control signal to the first travel actuator. A connecting member for receiving and transmitting the external travel control signal is removably connected to, and between, the first connecting portion and the second connecting portion.

Abstract: An article transport vehicle is provided which can prevent a lid from falling from the container gripped by grip portions and which can prevent increase in the size of the device. A lid fall prevention member is provided which can be moved between a near position in which the lid fall prevention member is close to the lid on the side the outer surface of the lid is located, to prevent the lid from falling, and an away position in which the lid fall prevention member is farther away from the lid to allow the lid to be detached and attached. An operatively connecting mechanism is also provided which moves the lid fall prevention member from the near position to the away position as a pair of the grip portions are moved from gripping positions to grip release positions by grip actuator portion, and which moves the lid fall prevention member from the away position to the near position as the pair of the grip portions are moved from the grip release positions to the gripping positions by the grip actuator portion.

Abstract: A ceiling transport vehicle in which articles may be transferred precisely while allowing its travel portion to travel smoothly along a set travel path is provided. The ceiling transport vehicle has a pair of guiding bodies which guide the travel portion along a set travel path by contacting each of right and left lateral sides of a guide rail with a pair of contacting members that are supported by the travel portion such that the contacting members can be moved away from each other and moved toward each other in a lateral width direction. The ceiling transport vehicle also has a switching portion for moving each of the pair of contacting members away from each other and toward each other to switch between a holding state and a holding release state.

Abstract: This invention provides an overhead carrier for transporting an article on a ceiling of an article conveying system can travel on curves with various curvatures so as to increase the layout flexibility of traveling rails. Driving wheels that move an overhead carrier along traveling rails and non-driving wheels that are rotated separately from the driving wheels are provided on the right and left of the transport direction of the overhead carrier. In a linear section, the driving wheels on the right and left sides are supported by the traveling rails. In a curved section, the inner non-driving wheel is supported by the inner traveling rail while the outer driving wheel is supported by the outer traveling rail.
