Stacker crane passage 1 extending in the left-right direction
A pair of front and rear racks 1 are erected on the floor so as to be zero. The rack 1 includes a plurality of front columns 2 arranged side by side at predetermined intervals, a rear column 2 arranged behind the front columns 2 with a predetermined interval therebetween, and a front and rear column 2. It has a large number of shelf beams 3 which are provided in pairs at the front and rear and are provided at predetermined intervals in the height direction. Needless to say, the upper surfaces of the pair of shelf beams 3 before and after are located in the same horizontal plane. The shelf beam 3
Is attached to the column 2 by a known fixing means such as a bolt, via a mounting piece 4 having an L-shaped horizontal section fixed to the left and right ends thereof by means such as welding. As shown in FIG. 4, at least one, specifically, two articles W are
It is placed so as to straddle a pair of shelf beams 3 before and after between left and right columns 2 adjacent to each other.

[0008] The side of the rack 1 facing the stacker crane passage 10 serves as an article entrance 20.

[0009] The shelf beam 3 on the article entrance 20 side
At least one, specifically two fork insertion recesses 22 opened upward and in the front-rear direction are formed in the (shelf beam 3 located between the left and right columns 2). As shown in FIG. 5, the shelf beam 3 on the side of the article entrance 20 has a vertical wall 3a having a fork insertion recess 22 and a vertical wall 3a.
a horizontal wall 3b connected to each upper edge of the vertical wall 3a, a horizontal wall 3c connected to the lower edge of the vertical wall 3a, and a hanging reinforcing piece 3d connected to the rear end of the horizontal wall 3b. And a vertical reinforcing piece 3d continuously provided at the rear end of the horizontal wall 3c. The upper horizontal wall 3b (not the lower horizontal wall 3b connected to the edge of the fork insertion recess 22) serves as an article placement portion. The shelf beam 3 on the side of the article entrance 20 is formed by bending a metal plate.

[0010] As shown in FIG.
(The shelf beam 3 other than the shelf beam 3 on the side of the article entrance 20) is vertically connected to a vertical wall 3a, a horizontal wall 3b connected to an upper edge of the vertical wall 3a, and a lower edge of the vertical wall 3a. A horizontal reinforcing wall 3c, a hanging reinforcing piece 3d connected to the rear end of the horizontal wall 3b, and a vertical reinforcing piece 3d connected to the rear end of the horizontal wall 3c.

A pair of upper and lower guide rails 18 are arranged in the stacker crane passage 10 so that the longitudinal direction is directed to the left and right, and the stacker crane 23 is guided by these guide rails 18 so as to be able to move left and right. , This stacker crane 23
A lift 26 which is movable up and down on a mast 25 provided on the traveling carriage 24, and a slide fork 27 which is provided on the lift 26 so as to be horizontally slidable in the front-rear direction by a known reciprocating mechanism. are doing. As is well known, the slide fork 27 performs an operation of projecting the article W downward and lifting the article W by raising the elevating platform 26 and retreating to the elevating platform 26 side, thereby drawing the article W into the elevating platform 26. , The article W on the shelf beam 3 or the like by the operation reverse to the above.
Can be taken down. The known sliding mechanism has a base provided on an elevating table 26, and an intermediate sliding body which is slidable back and forth on the base and has a slide fork 27 slidably back and forth. When the intermediate sliding body moves relative to the base, the slide fork 27 moves in the same direction and the same amount relative to the intermediate sliding body in conjunction therewith. As shown in FIG. 3, a gap H is formed between the front and rear end faces of the article W and the front and rear end faces of the slide fork 27 when the article W is on the slide fork 27. It puts the goods W on the shelf beam 3
When placing the slide fork 2 on the shelf beam 3 on the back side
This is to prevent collision and interference of the device 7. If necessary, the fork insertion recess 2 is formed in the shelf beam 3 on the rear side.
Needless to say, it is also possible to form 2.
With the operation described above, when the article W on the shelf beam 3 is taken out by the slide fork 27 and when the article W is put on the shelf beam 3 by the slide fork 27, the article W is formed on the shelf beam 3 on the article entrance 20 side. The slide fork 27 and the intermediate sliding body are fitted into the fork insertion recess 22, and collide with the shelf beam 3 on the article entrance 20 side.
Since there is no interference, there is no need to place the article W on a special pallet having a slide fork insertion space unlike the related art.

Among the pair of front and rear shelf beams 3, odd-numbered ones (excluding the first one) counted from below (except the first one) have a left-right length of "L" and a front-rear length of "M" ( A non-combustible plate (not shown) made of a rectangular flat plate (see FIG. 3) is fixed so as not to collide with or interfere with the slide fork 27 and the intermediate sliding body fitted into the fork insertion recess 22.

A vertical pipe 12, which is a water supply pipe for fire extinguishing, is disposed between the front and rear supports 2, and the vertical pipe 12 is fixed to the support 2 on the stacker crane passage 10 side by a known pipe fixing device (not shown). ing. In the above, "the front and rear struts 2
"The vertical pipe 12 is disposed between" means that the vertical pipe 12 is disposed in a space defined by the front and rear struts 2 or slightly protrudes. Accordingly, when viewed from the front, the vertical tube 12 is completely or almost hidden by the support column 2.

The lower end of the vertical pipe 12 is connected to a main horizontal pipe 13 (see FIG. 2) crawl on the floor surface.
Reference numeral 3 is connected to a tank (not shown) or the like. The upper end of the vertical tube 12 is closed. A branch pipe 15 located between the shelf beams 3 is connected to the vertical pipe 12, and a sprinkler head 16 located between the shelf beams 3 is connected to the branch pipe 15. More specifically, among the vertical tubes 12, odd-numbered tubes counted from the right have sprinkler heads 16 located between odd-numbered (excluding the first) shelf beams 3 counted from the bottom. Connected via a tube 15;
A sprinkler head 16 located between even-numbered shelf beams 3 counted from below is connected to the even-numbered vertical tubes 12 from the right through a branch pipe 15.
“Between the front and rear shelf beams 3” includes a part included in the virtual horizontal space including the front and rear shelf beams 3 even between the front and rear columns 2. Therefore, when viewed from the front, the branch pipe 15 and the sprinkler head 16 are completely hidden by the shelf beam 3 (or the support 2). It is needless to say that the sprinkler head 16 does not collide with or interfere with the slide fork 27 and the intermediate sliding body that fit into the fork insertion recess 22. The position of the sprinkler head 16 may be anywhere between the shelf beams 3 as long as the sprinkler head 16 does not collide with or interfere with the slide fork 27 fitted into the fork insertion recess 22 and the intermediate sliding body.

When a fire occurs, the nearby sprinkler head 16 operates to extinguish the fire.
