A water supply pipe 6 is arranged in the vertical direction on the front surface of the front column 2. The rack 1 and a stacker crane which travels along a passage formed between the racks 1 and takes articles in and out of each shelf of the rack 1 are provided.
An automatic warehouse is configured.

From the water supply pipe 6, a branch pipe 61 connected to the sprinkler head 7 disposed between the front and rear arms 3 through the side of the column 2 branches. The water supply pipe 6 is connected to a pressure tank (not shown) or a pressurized water supply device such as a pump. In the event of a fire, the heat melts the tip of the sprinkler head 7 so that the water is sprinkled vigorously. Has become. Since the water supply pipe 6 is arranged further in front of the column 2, the water supply pipe 6 having a large diameter can be arranged without interfering with articles placed on the shelf member 5, and a sufficient number of sprinklers can be provided. The head 7 can be mounted.

However, if the water supply pipe 6 is simply attached to the front surface of the front column 2, the water supply pipe 6 can be moved from the shelf member 5 in plan view.
Projecting into the passage of the stacker crane ahead, it is necessary to increase the width of the passage by the amount of the water supply pipe 6.
Is dead space. For this reason, by displacing the front column 2 on which the water supply pipe 6 is disposed toward the shelf member 5 (rear side) by the amount of the water supply pipe 6 from the front end of the shelf receiver 4, the water supply pipe 6 is also flat.
