Automated clean stock room

Abstract

An automated clean stock room employs an external air supply system having a plurality of fan filter units for supplying filtered clean air into the stock room, and an internal air circulation system having fans cooperating with air ducts and a plurality of filter screens to circulate and repeatedly remove pollution particles from the air supplied into the stock room. The fans of the internal air circulation system increase the speed of air flowing into a plurality of storage shelves provided by storage racks in the stock room, so that pollution particles in the air may be more quickly removed to upgrade the air cleanness in the stock room.

Description

FIELD OF THE INVENTION[0001]The present invention relates to a stock room, and more particularly to an automated clean stock room that is configured to increase the cleanness of storage shelves in the stock room.BACKGROUND OF THE INVENTION[0002]Currently, there are two types of stock room that are commonly adopted by pharmaceutical industry and manufacturers of wafer, thin-film transistor (TFT), and liquid crystal display (LCD). In the first type of stock room, clean air is supplied via an external air supply system located above a ceiling of a clean room, and the supplied clean air is guided by air ducts to side walls of the stock room and released, as shown in FIG. 1. The first type of stock room includes two rows of air ducts 204 located at two opposite sides of the stock room, first and second storage racks 201, 202 providing a plurality of storage shelves 203 for holding stored items, and an crane unit 30 for moving items stored or to be stored in the stock room. This first typ...

AI Technical Summary

Benefits of technology

[0006]A primary object of the present invention is to provide an automated clean stock room that is capable of enhancing the air circulation in the stock room to increase the cleanness of storage shelves thereof.

[0007]To achieve the above and other objects, the automated clean stock room according to the present invention includes an external air supply system for supplying filtered clean air into the stock room, and an internal air circulation system having fans cooperating with air ducts and a plurality of filter screens to circulate the clean air supplied into the stock room. The fans of the internal air circulation system draw in the clean air supplied by the external air supply system, and deliver the clean air to air ducts, so that the clean air is further filtered by the filter screens provided between the air ducts and a plurality of storage shelves in the stock room to remove pollution particles from the air. The filtered clean air entered the storage shelves then flows back to an inlet of the fans to complete one cycle of air circulation in the stock room. The stock room so configured is able to increase the volume and speed of air flowing into the storage shelves, so as to more quickly remove the pollution particles from the air, and effectively prevent the pollution particles from entering into the storage shelves to thereby upgrade the cleanness of items stored on the storage shelves in the stock room. Moreover, the automated clean stock room may be constructed and maintained at reduced costs without scarifying the air cleanness in the stock room.

Problems solved by technology

Therefore, pollution particles in the storage shelves 203 are not effectively removed therefrom by airflows.

However, this type of stock room requires a large quantity of slim type fan filter units 101 to thereby increase the manufacturing and maintenance costs of the stock room.

While the additional fan filter units 101 increase the cleanness of the stock room, they inevitably increase the manufacturing and maintenance costs of the stock room.
