Description

[Detailed description of the invention] Industrial field of application This invention is installed in a clean room where clean air is blown downward from the ceiling and the descending air is sucked below the floor. This relates to cargo storage equipment in a clean room used to store goods (cargoes).

2. Description of the Related Art In general, cargo storage equipment is composed of shelves having a plurality of compartment storage spaces in the vertical direction. Alternatively, articles are carried in and out by mechanical and automatic operations using a carry-in/out device.

Problems that the invention aims to solve In the conventional cargo storage equipment described above, dust and dust are generated from workers and loading/unloading equipment near the front opening of the shelf, and some of this dust is stored in compartments. It migrates to the space side and accumulates, which adversely affects the article.

The purpose of this invention is to prevent the migration of dust by flowing clean air from the rear side to the front side of the compartment storage space of each tier, and to prevent the transfer of dust etc. For space,
The object of the present invention is to provide cargo storage equipment in a clean room that can supply cargo in sufficient quantity, speed, and uniformity.

Means for solving the problem In order to solve the above problem, the cargo storage equipment in the clean room according to the present invention blows clean air downward from the ceiling side and sucks the descending air below the floor. A shelf having a plurality of compartment storage spaces is provided in the shelf, the front side of the shelf is open, and a cover is provided on the rear side, and a partition plate is provided in the cover to form a plurality of flow channels,
These channels and each compartment storage space are communicated in each stage, and the upper end of the cover is formed into a wide-mouth gathering part,
The configuration is such that the downward blowing clean air is supplied into this wide-mouth collecting section.

According to this configuration, the clean air blown downward from the ceiling is uniformly guided to each flow path in the cover, and the clean air in each flow path is distributed from the rear side to the front side in the divided storage space of each stage of the shelf. The clean air that is blown out toward the side can be collected in the wide-mouth collecting section and then supplied to each stage in a sufficient amount and at a sufficient speed.

Embodiment An embodiment of the present invention will be described below based on the drawings. 1 is a clean room, in which clean air 4 is blown down from the ceiling 2 side through a filter 3,
It is constructed so that the descending clean air 4 is sucked through a mesh-type floor 5 and below the floor 5. Reference numeral 6 denotes a shelf, which is composed of a box-shaped main body 7 with open front and rear surfaces, and a large number of horizontal partition plates 8 arranged vertically in parallel inside the main body 7.
As a result, a plurality of partitioned storage spaces 9 are formed in the vertical direction. A duct-shaped cover 10 made of SUS or resin (to prevent power overload) is disposed on the rear side of the shelf 6 over its entire surface, and a plurality of partition plates 11 are provided within this cover 10 to allow a plurality of partitions. 12 are formed, and these channels 12 communicate with the rear opening of each compartment storage space 9 in each stage. Further, the upper end of the cover 10 is open and approaches (or comes into contact with) the lower surface of the filter 3, so that the downwardly blown clean air 5 is supplied into the cover 10. The upper end of this cover 10 is formed into a wide-mouth gathering portion 10A, so that the flow path 1
The upper end of 2 is also formed in the wide-mouth channel 12A. 13 indicates an article (cargo).

In the above embodiment, inside the clean room 1,
The clean air blown downward through the filter 3 descends and the descending clean air 4 is sucked under the floor 5, so that its cleanliness is ensured. In the shelf 6, a large amount of clean air 4 blown downward through the filter 3 enters the wide-mouth collecting portion 10A of the cover 10, is compressed into each wide-mouth channel 12A, flows through each channel 12 at high speed, and then flows through each channel 12 at high speed. The water is uniformly supplied to each compartment storage space 9 of each stage from the rear side, and after flowing through each compartment storage space 9, it flows out into the clean room 1 from the front.

Effects of the invention According to the cargo storage equipment in a clean room according to the invention having the above configuration, the clean air blown downward from the ceiling is uniformly guided to each channel in the cover, and the clean air in the cover is distributed to each of the shelves. In the partitioned storage space of the stage, the flow can be made from the rear side to the front side, and therefore it is possible to prevent dust and dust from entering the partitioned storage space from the front side. In addition, the clean air blown downward is collected at the wide-mouth gathering part,
Since it is evenly distributed to each flow path divided by a partition plate and then supplied to each stage, even though the downward blowing force is set for a clean room, sufficient amount and speed can be supplied to each stage. Moreover, it can be supplied uniformly. Furthermore, since clean air uses a portion of the air supplied into the clean room, compared to, for example, a filter installed on the entire rear surface of the shelf and air supplied by a fan,
Power and maintenance can be eliminated, the entire structure can be obtained at low cost, and space can be saved.
