Guide rails for an article transport vehicle are provided and include a pair of right and left rail portion which are spaced apart from each other in a rail lateral direction. The guide rails are diverged into a straight forward path, a left diverging path, and a right diverging path at a three-directional diverging portion of the travel paths. The pair of right and left rail portions provided along the straight forward path are spaced apart in the path longitudinal direction from the pair of right and left rail portions provided along the upstream-side travel path of the three-directional diverging portion. In addition, an auxiliary receiving mechanism is provided for receiving and supporting the article transport vehicle traveling between the pair of right and left rail portion of the upstream-side travel path and the pair of right and left rail portions of the straight forward path.

Ceiling installation type article transport facility

A floating unit comprises: a stationary portion; a movable portion supported to be movable relative to the stationary portion and including an article support; a support disposed between the stationary portion and the movable portion, the support having a plurality of rolling elements rotatably held by a holder between an upwardly facing first contact surface provided on the stationary portion and a downwardly facing second contact surface provided on the movable portion, whereby the support is movable in all horizontal directions relative to the movable portion and the stationary portion; a movable portion returning device for biasing the movable portion relative to the stationary portion toward a reference position for receiving an article; and a support returning device for biasing the support horizontally relative to the stationary portion toward a reference position for holding the movable portion.

Floating unit, and an article support apparatus having floating units

Article sensor for detecting an article on an article holder has an article detecting portion for detecting the presence or absence of an article and a wireless communication unit capable of wirelessly transmitting detected information from the article detecting portion. The article detecting portion and the wireless communication unit are assembled into a unit.

It is an object of the present invention to provide a plate-shaped work piece transporting apparatus that has a fan, a dust-removal filter disposed above this fan, and a plate-shape porous member disposed above the dust-removal filter. By forming a chamber in which air can accumulate between the porous member and the dust-removal filter, it is possible to suppress air pulsations. Further, by providing support members on the porous member, the plate-shaped work piece can be supported and damage thereto can be avoided when the plate-shaped work piece, which is supported by air from the fan, drops to below a set height.

Plate-shaped work piece transporting apparatus

It is an object to provide a plate-shaped work piece transporting apparatus provided with a blowing mechanism for contactlessly supporting a plate-shaped work piece that is transported, where the blowing mechanism is provided with a dust-removal filter and a blowing mechanism for sending air to the lower surface of the plate-shaped work piece via the dust-removal filter. In a first embodiment, a driving mechanism for contacting the plate-shaped work piece and moving it in the transporting direction is provided.

Apparatus for transporting plate-shaped work piece

A magnetic levitation transport system includes magnetic levitation vehicles each driven by a linear motor to run along a track. Induction lines extend through predetermined blocks of the running track to transmit a high frequency sine-wave current. Each vehicle includes electromagnets to attract levitating magnetic members extending along the running track, a pickup coil resonant with a frequency of the induction lines to generate an electromotive force, and a battery chargeable by the pickup coil. The electromagnets receive power from the pickup coil and/or the battery.
