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).

BACKGROUND TECHNOLOGY In general, cargo storage equipment includes a shelf that has a plurality of compartment storage spaces in the vertical and horizontal directions, and a loading/unloading tool that can move freely along a fixed path along the shelf and can move up and down as well as move in and out in the horizontal direction. Furthermore, the carrying-in/out device travels by supporting and guiding the guided body on the lower rail and the upper rail, respectively.

Problems that the invention aims to solve: According to such conventional cargo storage equipment, a lot of dust is generated due to wear and tear on the part where the guide body is supported and guided by both rails, especially on the upper rail side. Since the dust is located near the shelves, the generated dust will not be sucked to the floor but will migrate to the cargo stored on the shelves, which will have an adverse effect on the cargo. For these reasons, it has been considered difficult to mechanize and automate cargo storage in clean rooms, that is, to adopt cargo storage equipment.

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. The loading/unloading device is provided with a shelf having a plurality of compartment storage spaces in the horizontal direction, and a loading/unloading device that can move freely on a fixed path along the shelf and has a loading/unloading device that can be moved up and down and moved in and out in the lateral direction. has a lower guided body supported and guided by a lower rail, and an upper guided body guided by an upper rail, the lower rail and the lower guided body are provided in a dustproof cover, and the upper rail and the upper A suction duct that covers the guided body over the entire length of the predetermined path is provided, and the suction part of the suction duct is a slit that allows passage of a support member for connecting the upper guided body and the loading/unloading device, The discharge part is a suction port connected to a suction device.

According to the configuration of the present invention, the dust generated when the lower guided object is supported and guided by the lower rail is prevented from moving into the clean room by the dust cover, and the upper guided object is supported and guided by the upper rail. Dust generated by being guided can be removed without moving into the clean room by the suction force of the air acting in the suction duct.

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 air is sucked under the floor through a mesh type floor 5. Reference numeral 6 denotes a shelf, which includes a box-shaped main body 7 with an open front, a large number of vertical frames 8 arranged horizontally in parallel within this main body 7, a large number of front and rear frames 9 attached to these vertical frames 8 in the vertical direction, and A loading/unloading port 11 is formed by cutting out the main body 7 at the lower part.
It consists of an inlet loading tray 12 and an unloading loading tray 13 that protrude to the back side through the loading/unloading opening 11, and a plurality of compartment storage spaces are created in the vertical and horizontal directions by the frames 8, 9, etc. Form 14. Reference numeral 15 denotes a loading/unloading device, which is movable along a fixed path 16 along the front side of the shelf 6. That is, the carry-in/out device 15 has a main body formed of a square cylindrical post 17, and a sliding body (an example of a lower guided body, which is an example of a lower guided body, instead of a roller etc. ) 19 is installed. This slide body 19 is attached to the main body 7 side of the shelf 6 and is supported and guided by a lower rail 20 along the constant path 16. A mounting member 21 is provided vertically from the lower surface of the post 17, and this mounting member 21 is connected to one point of an endless rotating body 22 provided on the main body 7 side, and the endless rotating body 22 can be rotated in forward and reverse directions via a wheel or the like. It is linked to the drive device 23. The lower rail 20, forward/reverse drive device 23, etc. are included in the main body 7.
The dustproof cover 24 is provided within a dustproof cover 24 that is integrated with the housing, and slits 25 and 26 are formed in the dustproof cover 24 to allow movement of the bracket 18 and the mounting member 21.

A pair of idling rollers (which is an example of an upper guided body and can be replaced with a sliding body, etc.) 28 are disposed at the upper end of the post 17 via a support member 27, and between these idling rollers 28, An upper rail 29 located along the fixed path 16 is attached to the main body 7 side via an attachment member 30. The upper rail 29 and the idle roller 28 are arranged along the entire length of the fixed path 16 and are attached to the mounting member 30.
The suction duct 31 is disposed within a suction duct 31 supported on the side, and the suction duct 31 is formed with a suction port 32 that is linked to a suction device (not shown) and a slit 33 that allows movement of the support member 27. The loading/unloading device 15 is supported and guided by both rails 20 and 29 and can freely travel on a fixed path 16, and a slit 34 is formed in the vertical direction on one of the surfaces of the post 17 in the running direction. Inside the post 17 are an upper wheel body 35 and a lower wheel body 3.
6, a driving wheel body 37 etc. are arranged, and these wheel bodies 3
An endless rotating body 38 is wound between 5, 36, and 37, and the drive wheel body 37 is linked to a forward/reverse drive device 39. An elevating body 40 connected to one point of the endless rotating body 38 is guided by a vertical rail 41 disposed within the post 17, and a connecting member 42 from the elevating body 40 projects through the slit 34.
An elevating table 43 is attached to the protruding end of the connecting member 42, and a loading/unloading tool 44 that can be moved in and out in the horizontal direction is provided on the elevating table 43, so that it can be moved between the cargo receiving tables 12, 13 and the compartment storage space 14. This makes it possible to receive and receive cargo 45.

The operation of the above embodiment will be explained below. Inside the clean room 1, the clean air 4 that is blown downward through the filter 3 descends, and the descending air is sucked below the floor 5, so that its cleanliness is ensured. In such a clean room 1, using the loading/unloading device 15, the partitioned storage space 14 targeted by the shelf 6 and both cargo receiving platforms 12, 13 are
The delivery of the load 45 between the
This can be performed by a combination of the lifting and lowering operations of step 3 and the moving and retracting operations of the loading/unloading tool 44. At this time, dust generated when the slide body 19 is supported and guided with respect to the lower rail 20 is prevented from coming out into the clean room 1 by the dust cover 24. In addition, dust generated when the idle roller 28 is guided by the upper rail 29 is removed from the suction duct 3.
1 prevents scattering, and the suction duct 3
Due to the air suction force acting within the clean room 1 , it can be removed without moving into the clean room 1 .

Effects of the invention According to the invention having the above configuration, in a clean room with a ceiling blowout and underfloor suction type, the dust generated when the lower guided body is supported and guided by the lower rail is prevented from migrating into the clean room by the dust cover. It can be prevented. In addition, the dust generated when the upper guided object is guided by the upper rail is removed by the suction force of the suction device acting in the suction duct, and the clean air sucked from the slit in the suction duct is discharged to the suction port. By doing so, it can be removed without moving into the clean room. This makes it possible to prevent dust generated in the guide section from moving to the shelf side, thereby making it possible to mechanize and automate cargo storage in a clean room.
