Background of the invention

The article storage device is such that the article transporting vehicle travels in the lateral width direction of the rack of the article storage rack, and the article transporting device is raised and lowered in the up and down direction, and is used for the glass substrate used for the semiconductor product, the liquid crystal display or the plasma display. An article such as a container that is stored in a stacked state such as a liquid crystal display element is transported between the article storage unit and an article processing apparatus that performs processing on a semiconductor product or a liquid crystal display element.

Further, the air air ventilating mechanism is provided so that the purified air flows from the back side of the article storage unit toward the transporting vehicle moving space, passes through the article accommodating portion, and flows downward in the moving space of the transporting vehicle, and then flows into the arranging row. By the discharge of the gas portion, the dust which is raised from the floor portion is less likely to flow back from the transport space of the transport vehicle to the article storage portion, and the article storage portion can be maintained in an environment where there is little dust (see Japanese Patent Laid-Open Publication No. 2003-81406).

The article storage device includes a shelf that traverses the object storage rack below the article storage unit in a state in which the article storage portion of the article storage rack is separated from air and cannot flow, and the air in the transport space of the transport vehicle is allowed to flow. The air flow space formed by the lateral width direction is approximately the entire length. Further, if there is an air guiding body, the air guiding system is viewed in the traveling direction of the article transporting vehicle, and is at the same height as the upper portion of the end portion side in the lateral width direction of the traveling frame of the traveling frame or The state in which the one end region of the moving space of the transport vehicle protrudes from the front and rear direction of the rack to the moving space of the transport vehicle is formed to be approximately the entire length of the lateral width of the rack of the article storage rack.

By setting the air flow space, when the article transport vehicle is walking, the purified air in a compressed state on the front side of the traveling direction of the traveling frame easily flows to the air flow space on the lateral side of the traveling frame, and the air purification can be suppressed. The upper side of the traveling frame flows, and the dust rises on the front side of the traveling frame.

Further, by providing the air guiding body, the purified air does not easily flow from the floor portion side to the upper side of the air guiding body, and the airflow of the purified air flowing to the air flowing space due to the traveling of the article transporting vehicle can be suppressed, and the dust is in the frame. The side of the side or the side of the side of the walk is raised. Therefore, the article accommodating portion can be maintained in an environment where there is little dust even if the wind of the purified air flowing through the clean air ventilating mechanism is small (refer to Japanese Patent Laid-Open Publication No. 2000-16518).

In recent years, with the increase in size of liquid crystal display elements such as glass substrates, the article storage equipment has also increased in size. In large-sized article storage facilities, the travel distance of the article transport vehicles has increased. Therefore, in order to improve the transport efficiency of articles, it is expected that the articles will be transported. High-speed walking. However, the above-mentioned conventional article storage device has a rectangular shape extending in the traveling direction on the lower surface and the upper surface of the traveling frame, and a rectangular shape extending in the vertical direction on the left and right lateral sides, and the wheel extends from the lower side to the lower side, and is compressed in a compressed state on the traveling direction side of the vehicle. As the amount of air increases, when the article transport vehicle travels at a high speed, the amount of purified air flowing above or on the lateral side of the article transport vehicle increases, and dust tends to rise. Therefore, it is difficult to maintain the article storage unit in an environment with little dust, and it is necessary to increase the wind of the purified air flowing through the purified air ventilation mechanism in order to maintain the article storage unit in an environment where there is little dust.

Further, in the conventional article storage device, when the article transport vehicle travels in the transport vehicle moving space in front of the article storage rack, the purified air that is placed in the pillar that is erected on the traveling frame flows to the article storage rack side, thereby purifying Since the air is easily flowed back from the moving space of the transport vehicle to the side of the article storage unit, it is necessary to increase the wind of the purified air flowing through the purified air ventilation mechanism in order to maintain the article storage portion in an environment where the dust is small.

It is an object of the present invention to provide an article storage apparatus which can easily maintain an article storage portion in an environment with less dust, by at least one of the problems of the above-mentioned prior art, even if the wind of the purified air flowing through the air purifying mechanism is small. .

In order to achieve the object, the article storage device of the present invention is provided with an article storage rack, an article transport cart, a purifying air ventilation mechanism, an air flow space, and an air guiding body: the article storage rack has a plurality of article storage portions; The transport vehicle has a traveling frame that travels on a floor portion of the transporting vehicle moving space in front of the article storage rack, and a moving object that is supported by the moving frame to be lifted and lowered; the purified air venting mechanism purifies The air flows from the back side of the article storage unit toward the transport vehicle moving space, passes through the article storage unit, and flows the purified air to the lower side in the transport space of the transport vehicle, and then flows out from the exhaust unit; The air flow space is configured such that the object storage portion of the article storage rack is separated from air so that the air cannot flow, and the transport space of the transport vehicle is movable in the air, and the rack of the article storage rack is placed under the article storage portion. Approximately the full length of the transverse width direction; the air guiding system is in the aforementioned article transport vehicle When viewed in the traveling direction, the height is equal to or higher than the upper portion of the upper end portion of the vehicle in the lateral width direction of the traveling frame, and protrudes from one end region of the transporting vehicle moving space in the front-rear direction of the traveling frame to In a state in which the transport vehicle moves into the space, the vehicle is formed so as to extend over the entire width direction of the rack of the article storage rack; the air travel path is formed in the travel frame, and the air flow path is in the vehicle of the travel frame. Both ends of the direction are opened to allow air to enter and exit, and the openings between the both ends are communicated to allow air to flow.

That is, since the air flow path is formed in the traveling frame, a part of the purified air on the front side of the traveling direction of the traveling frame can be passed through the air flow path to the rear side of the traveling direction of the traveling frame of the traveling frame, so that the article When the transport vehicle is traveling, the amount of purified air that is compressed in the traveling direction side of the traveling frame is small, so that the amount of purified air flowing on the upper side or the lateral side of the traveling frame can be reduced.
