A method for supplying inert gas to a side track buffer (STB) in a semiconductor wafer production system includes a step of sensing that a front opening unified POD (FOUP) is loading on the STB and generating a first input signal, and a step of opening a valve for inert gas and supplying nitrogen gas to the FOUP based on the first input signal, and to a semiconductor wafer production system using the method.

A conveying apparatus that increases the conveying speed of a conveyance object, and improves reliability and conveyance efficiency at low cost. Acceleration/deceleration sections, each of which includes a plurality of variable-speed conveyance sections, are provided among constant-speed conveyance sections. The conveying speed of a conveyance object is continuously accelerated or decelerated while the conveyance object passes through the acceleration/deceleration sections. This changes the conveying speed from the conveying speed of the upstream constant-speed conveyance section to the conveying speed of the downstream constant-speed conveyance section. Thus, it is controlled that the conveying speed and the conveyance acceleration/deceleration is identical between the upstream conveyance section and the downstream conveyance section when the conveyance object is transferred from the upstream conveyance section to the downstream conveyance section.

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. A flange portion configured to allow the storage and retrieval transport apparatus to hold the reticle container using the holding unit to support the reticle container in a hanging state is formed at an upper portion of the reticle container.

A transport device that can transport stacked articles to be transported without changing a device configuration and can correct and prevent a displacement of the stacked articles to be transported with a simple device configuration. A chucking device is provided to hold trays in a stacked state. The chucking device is provided with an overhead carriage for transporting the trays held by the chucking device. The chucking device includes a holding unit that holds the trays and sensors that detect the trays held by the holding unit. The holding unit is configured such that the holding operation of the holding unit on the trays is controlled based on detection of the sensors, and correct and prevent a displacement of the stacked trays.

An article transport facility includes a traveling rail hung from a ceiling portion and configured for guiding an article transport carriage, an article loading unit disposed laterally and downwardly of the traveling rail and configured for loading and supporting an article to be transferred to/from the article transport carriage, and a supporting mechanism for supporting the article loading unit hung from the ceiling portion in such a manner that the article loading unit is rendered position-adjustable between a transferring position for transferring the article to/from the article transport carriage and a retracted position retracted upwards from the transferring position. The supporting mechanism is capable of causing the article loading unit loading an article thereon to be position-changeable between the transferring position and the retracted position.
摘要:
A transporting space of an article transport facility is divided into a first space and a second space by a wall having an opening. A first movable body that travels along a first travel rail in the first space and a second movable body that travels along a second travel rail in the second space are provided. A relay portion which can support an article without interfering with the shutter that can open and close the opening is provided in the first space. The first travel rail is arranged to extend adjacent a first space side transfer position for transferring articles between the first mobile body and the relay portion, and the second travel rail is arranged to extend adjacent a second space side transfer position for transferring articles between the second mobile body and the relay portion through the opening.

A transport device includes a traveling holding member which can travel while holding a storage container, and a move out prevention mechanism which prevents substrates from moving out of an opening of the storage container. The move out prevention mechanism is configured to include a contacting member which can be moved between a contact position at which the contacting member is in contact with side faces of the substrates, and a spaced apart position at which the contacting member is spaced apart from the side faces of the substrates. The contact position is set such that the contacting member is located between an opening side end portion and a central portion of the substrates in a direction along which the substrates are inserted and removed.
摘要:
Articles are stored while preventing disruption of the flow of clean air from an upper region to a lower region to alleviate degradation of clean air with an article supported by an article support. The article support (28) is provided with a movable body (30) which is supported to a fixed frame (29) to be movable in a far-near direction with respect to a travel path and which is formed to extend downwardly from the fixed frame (29), and a support member (31) formed to extend in the far-near direction from a lower end portion of the movable body (30). The support member (31) consists of a contact support portion (40) which is narrower than the width of an article in a direction along the travel path and which extends in the far-near direction from a lower end portion of the movable body, and a movement restricting portion (41) which extends in a direction along the travel path from the contact support portion (40), which has a vertical wall (41a) which contacts a side surface of an article, and which is narrower than the article in the far-near direction.
摘要:
A workpiece elevating support device which can be utilized by being installed in a carriage-type conveying apparatus for conveying an automobile body while changing the height thereof in each section in an automobile assembly line. The workpiece elevating support device includes at least two center-folding double link mechanisms arranged in parallel on a base, each of which is composed of a lower parallel link, an intermediate link member, an upper parallel link, and an upper link member. The upper link member is consecutively provided with a workpiece support. There is juxtaposed a lock to hold the center-folding double link mechanisms in an expanding-rising posture, which is taken when the upper link members are vertically raised to a predetermined height.
摘要:
An article transfer system that allows the operator to easily notice that abnormality occurs in an abnormality detecting sensor for detecting abnormality and perform remedial work is provided. The article transfer system is adapted to display information indicating that the abnormality occurs on a display device as abnormality occurrence information, receive input of a result of determination by the operator on whether or not the abnormality indicated by the abnormality occurrence information occurs, and display information indicating that the detecting information received from the abnormality detecting sensor is incorrect on the display device when the operator inputs the result of determination that the abnormality indicated by the abnormality occurrence information does not occur with the abnormality detecting sensor detecting the abnormality.
