Inter-floor transport facility

An article transport facility comprises storage sections, a transport device, a controller, and a learning module. The transport device has a transfer device having a support portion, and a light-emitter-receiver. The controller is caused to store information that indicates a second target position at which the transfer device is located when transferring an article, and information that indicates a first target position to which the support portion is moved. Each of a plurality of storage sections is provided with a reflector. A learning control performed by the controller is a control in which a first target position and a second target position are learned based on information of an image of the reflector captured by the imaging device of the learning module and pre-learning position information. Each reflector has a first area which forms the periphery of the reflector, and a second area in the first area. The relationship between the reflectance and the wave length of the reflected light is different between the first area and the second area.

A support body includes a protrusion that protrudes in the horizontal direction from a base and passes through a notch in the vertical direction when a container is transferred, and the lateral width of the protrusion is formed to be narrower than the lateral width of the container. A small container and a large container configured to be wider than the small container in the lateral width direction exist as the container. The support body includes, as support body-side supporting parts, three support body-side small container supporting parts that support three small container supported parts located on the bottom surface of the small container, and a support body-side edge supporting part that supports an edge of the outer periphery of the bottom surface of the large container near the base.

Container transport facility

An article storage facility includes a measuring jig for measuring an amount of tilt of a support body. A controller for controlling operation of an article transport device performs a tilt measurement control for controlling operation of the article transport device to transport the measuring jig sequentially to each of a plurality of measurement target storage sections which is all or part of the plurality of storage sections.

Article storage facility

A vertically moving device includes a spool mechanism for spooling at least two wires that are fed out to form loops and a vertically movable platform suspended by looped portions of the at least two wires fed out from the spool mechanism. The vertically movable platform includes at least four wire-guiding rotating bodies over which the looped portions of the wires are run. And a looped portion of one of the wires is run over at least two of the wire-guiding rotating bodies, and a looped portion of the other of the wires is run over at least two other of the wire-guiding rotating bodies

Vertically moving device

An article storage facility includes a storage rack configured to store a semiconductor wafer and a reticle, and a storage and retrieval transport apparatus. The storage rack includes a first accommodation unit configured to store a wafer container for containing the semiconductor wafer, and a second accommodation unit configured to store a reticle container for containing the reticle. The storage and retrieval transport apparatus includes a holding unit configured to hold a top flange formed at an upper portion of the wafer container to support the wafer container in a hanging state.
