DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fire extinguisher for an automatic warehouse.

[0002]

2. Description of the Related Art Conventionally, the following types of automatic warehouses are known. That is, a pair of front and rear rack devices having a large number of article storage shelves vertically and horizontally provided at predetermined intervals in the front and rear direction, and a stacker crane provided to be able to move left and right between the front and rear rack devices. The stacker crane comprises a traveling vehicle, a lifting / lowering platform movable on a mast provided on the traveling vehicle, and an article transfer device (for example, a front-rear direction) provided on the lifting / lowering platform. (A slide fork) slidably provided on the front surface is known.

[0003]

SUMMARY OF THE INVENTION It is an object of the present invention to enable a sprinkler to operate more quickly and surely without installing a separate heat collecting plate in the automatic warehouse.

[0004]

Means for Achieving the Object The present invention employs the following means to achieve the object. The present invention provides a heat collecting plate between front and rear struts arranged at predetermined intervals.
And a sprinkler head is disposed below the article support plate without any intervening member that hinders the transfer of heat .

[0005]

The present invention has the following functions. When a fire occurs, the article support plate in the vicinity acts as a heat collecting plate and immediately becomes hot, so that the sprinkler head below operates quickly and reliably (for example, the part blocking the sprinkler port melts). T) Watering is performed and fire is extinguished.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to embodiments shown in the drawings. In this specification, the front means the lower side in FIG. 1, the rear means the upper side in the figure, the left means the left side in FIG. 1, and the right means the right side in the figure.

[0007] A pair of front and rear rack devices 1 are erected on the floor so as to open the stacker crane passage 10. The rack device 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 front and rear columns 2. A plurality of article support plates 4 provided at predetermined intervals in the height direction and projecting right and left, and a pair of left and right article support plates 4 facing each other without the support column 2 interposed therebetween. The parts form an article storage shelf 3. A space between the pair of left and right article support plates 4 is a fork passage gap 5 that allows the slide fork 17 to be described later to move in the vertical direction. The entrances 6 of the article storage shelves 3 of the front and rear rack devices 1 face each other.

The article support plate 4 is made of a metal having a high thermal conductivity, and includes a horizontal portion 4a for supporting the article W and a horizontal portion 4a.
and a drooping portion 4b provided in a drooping shape on the entire peripheral edge of a. The horizontal portion 4a has a size of 1200 cm ² or more and a short side of 20 cm or more, and thus functions sufficiently as a heat collecting plate specified by the Fire Service Law. Immediately below the required one of the article support plate 4, a part that prevents heat transmission
Known sprinkler head 2 without any intervening material
0 is located. The sprinkler head
20 is surrounded by a horizontal portion 4a and a hanging portion 4b.
It is located in the space on the lower surface side of the horizontal portion 4a to be inserted. Specifically, the sprinkler heads 20 are located directly below every other article support plate 4 in the left-right direction, and the sprinkler heads 20 are located directly below every other article support plate 4 in the height direction. Have been allowed. The number and positions of the sprinkler heads 20 are arbitrary as long as legal requirements are satisfied. The sprinkler head 20 is connected to a branch pipe 23 connected to a horizontal pipe 22, and the horizontal pipe 22 is connected to a vertical pipe 21 connected to a water pipe (not shown). With such a configuration,
When a fire occurs, the article support plate 4 in the vicinity acts as a heat collecting plate and immediately becomes hot, so that the sprinkler head 20 therebelow is activated (the part closing the water spout is melted) and water is sprinkled. The fire is extinguished.

On the left side of the rack device 1, there is provided a loading / unloading roller conveyor 8 whose transport direction is in the left-right direction. Rack device 1 of this loading and unloading roller conveyor 8
A known article elevator (not shown) is provided on the side.
The article elevator includes a lifting platform that can be raised and lowered by a known lifting device below the rollers of the loading and unloading roller conveyor 8,
It has a pair of support frames that are erected on the lift table and are located between the rollers of the entrance and exit roller conveyor 8. The article elevator lifts the article W by the support frame to form a fork insertion gap between the transport surface of the loading / unloading roller conveyor 8 and the lower surface of the article W, or the slide fork 1 by the support frame at the raised position.
The article W is received from the storage 7 and then lowered to drop the article W onto the loading / unloading roller conveyor 8.

A pair of upper and lower guide rails 11 are disposed in the stacker crane passage 10 so that the longitudinal direction thereof is directed to the left and right. , This stacker crane 13
A lift 16 which can be moved up and down on a mast 15 provided on the traveling carriage 14, and a slide fork 17 which can be horizontally slidably moved in the front-rear direction by a known reciprocating mechanism on the lift 16 doing. As is well known, the slide fork 17 performs an operation of projecting the article W downward and lifting the article W by the elevation of the elevator 16 and retreating to the elevator 16 to draw the article W into the elevator 16. By the operation reverse to the above, the article W can be dropped on the article storage shelf 3 or the like.

[0011]

According to the present invention, the following effects can be obtained by the above configuration. According to the first aspect of the present invention, the article support plate itself serves as a heat collecting plate.
Act between the article bearing plate and the sprinkler head
Does not have a heat blocking member,
During birth, the product support plate becomes hot immediately, and the heat collecting plate
Sprinkler head located below even if not provided
Can be operated quickly. Separate heat collecting plate
Because there is no need to install, the number of parts is reduced
Can be easily assembled and cost can be reduced.
I can do it. Furthermore, since the article support plate also serves as a heat collecting plate,
That is, an article bearing plate of a considerably large area passed between the pillars
Can be used as a heat collecting plate to quickly heat up in the event of a fire.
Can be captured. In the invention of claim 2, the horizontal portion and the hanging portion of the article support plate
The tip of the sprinkler head in the space surrounded by
Is located, so the sprinkler head is located
At a location where heat is likely to accumulate in the event of a fire,
When raw, the sprinkler head is activated more quickly.
Can be sprinkled.
