DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rack for use in an automatic warehouse or the like, and more particularly to an arrangement of a water supply pipe of a fire extinguishing sprinkler head.

[0002]

2. Description of the Related Art In an automatic warehouse, a rack is used in which a plurality of rack units, each having a rack support provided between a pair of front and rear columns, are provided on the right and left sides. Then, for example, a plurality of racks are provided, rails are laid between the racks, and a stacker crane is driven to move articles into and out of the racks. By the way, attention is paid to taking digestive measures in automatic warehouses. And the basis of digestion is to arrange the sprinkler head on the rack.

However, one of the basic performances of automatic warehouses and their components in racks is the widest possible frontage and the deepest possible frontage. In other words, the storage capacity of articles is a basic performance in an automatic warehouse or rack, and the sprinkler head needs to be disposed without narrowing the frontage. The problem with the installation of the sprinkler head is the water supply pipe, without forming a dead space,
In addition, it is necessary to increase the fire extinguishing ability by allowing a large water supply pipe to be attached to which many sprinkler heads can be attached.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a water supply pipe for a sprinkler head without reducing the width of a rack or the depth of the width, that is, without producing a dead space. An additional problem with the invention of claim 2 is that
An object of the present invention is to minimize the displacement of a rear support column for connecting a water supply pipe to a front side. An additional object of the third aspect of the present invention is to prevent the spread of fire in the rack, partially eliminate the need for a water shield plate of the sprinkler head, and eliminate the dead space for the water shield plate.

[0005]

According to the first aspect of the present invention, there is provided a rack in which a plurality of rack units each having a shelf support provided between a pair of front and rear columns are provided side by side, and the front columns are displaced rearward. A first water supply pipe of the sprinkler head is vertically piped in a space, and a second water supply pipe is vertically piped in a space obtained by displacing a rear support column to a front side. If a rail is laid facing the front of the rack and a stacker crane or the like is run, it becomes an automatic warehouse.

The invention according to claim 2 is characterized in that the rear strut deflected to the front side is relatively thinner than the other rear struts.

The invention according to claim 3 is characterized in that a horizontal barrier is provided on a predetermined layer of the rack, and at least a part of the sprinkler head is arranged below the barrier.

[0008]

According to the first aspect of the present invention, the first water supply pipe is provided in a space obtained by displacing the front support column toward the rear side (the rear side of the rack). Can be arranged without dead space. In addition, since the second water supply pipe is provided in a space obtained by displacing the rear support column toward the front side, the water supply pipe can be provided without any dead space.

According to the second aspect of the present invention, furthermore, the column on which the rear water supply pipe is provided is made relatively thinner than the other columns on the rear side, so that the deflection of the front surface of the column to the front can be minimized. For this reason, it is possible to more stably support the shelf receiver on which the articles are placed.

According to the third aspect of the present invention, the horizontal barrier prevents the spread of fire to the upper part of the rack and the like, and the horizontal barrier is used also as the water shield plate of the sprinkler head, so that the dead space due to the water shield plate can be reduced.

1 to 3 show an embodiment. In each figure,
Reference numerals 2 and 4 denote rack units, and a plurality of rack units are provided on the left and right sides. In the embodiment, the pair of racks are integrated so that the columns and the columns face each other back to back. 8, 9,
The columns 10 and 11 are relatively large in diameter, and the columns 8 and 9 are used for the rack unit 2, and the columns 10 and 11 are relatively small in diameter and used for the rack unit 4. The columns 8, 10 are front columns, the columns 9, 11 are rear columns, and the rack units 2, 4 are, for example, arranged alternately. 12 is shelf support, 13
Are placed in the rack unit 2 by lattice. Reference numeral 14 denotes a horizontal beam, and reference numerals 15 and 16 denote joints. The joints 15 connect the rear supports 9 and 9 to be connected to the horizontal beam 14, and the joint 16 connects the supports 11 and 11 to be connected to the horizontal beam 14. I do. For example, a plurality of rows of the racks of the embodiment are arranged, and rails are laid between the racks as traveling passages of a stacker crane or the like, thereby forming an automatic warehouse. However, the rack of the embodiment can be used for other than the automatic warehouse.

Reference numeral 18 in FIGS. 2 and 3 denotes a horizontal barrier, which is made of a nonflammable thin plate and prevents the spread of fire to the upper part of the rack or the like. The horizontal barrier 18 is provided for each of a plurality of layers such as, for example, two to three layers of the rack, considering the rack as one layer for each shelf support 12. Reference numerals 20 and 21 denote water supply pipes for supplying water to the sprinkler heads 22 to 25, which are connected to the front side of the rack units 2 and 4 as first water supply pipes 20, and connect the sprinkler heads 22 and 23. A pipe provided in a space obtained by displacing the support 11 to the front side is used as a second water supply pipe 21.
And sprinkler heads 24 and 25 are connected to branch pipes 27 and 2
8. The water supply pipes 20, 21 may have a common or different pipe diameter.

The sprinkler heads 22 and 23 are arranged on the front of the rack below the horizontal barrier 18, and the sprinkler head 22 provided below the odd-numbered horizontal barrier 18 is provided below the even-numbered horizontal barrier. This is referred to as a sprinkler head 23. The sprinkler heads 22 and 23 also use the horizontal barrier 18 as a water shield 26 described later. Sprinkler head 24,
Numerals 25 are alternately provided near the boundary between racks of the layer without the horizontal barrier 18. For example, if the sprinkler head 24 is provided above the odd-numbered horizontal barrier, the sprinkler head 2 is provided above the even-numbered horizontal barrier.
5 is provided. Reference numerals 27 and 28 denote branch pipes arranged below the horizontal beam 14 and the like.
Supply water to 25.

Each of the sprinkler heads 22 to 25 is formed of a sprinkler tube plugged with a heat-sensitive resin, and sprays 360 degrees around the circumference when the heat-sensitive resin is melted by heat in a fire. The configuration of the sprinkler heads 22 to 25 is arbitrary. 2
Numeral 6 is a water shield plate, which cools the heat-sensitive resin of the lower sprinkler head to prevent water from flowing from the upper sprinkler head and prevents it from being sprinkled, and at the same time, stores a hot airflow at the time of a fire and melts the heat-sensitive resin with the heat. It is for. The water impervious plate 26 is provided for the sprinkler heads 24 and 25, and the height thereof is substantially the same as that of the shelf receiver 12, thereby preventing the occurrence of dead space. Sprinkler head 2
Since the horizontal barrier 18 is also used as a water shield in the members 2 and 23, the water shield 26 is unnecessary. 3 indicate the frontage and the height thereof, and the pallet 30 on which the article 32 is placed is accommodated in this frontage.

The features of the embodiment will be described. As shown in FIG. 1, the columns 8 and 10 on the front side of the rack units 2 and 4 are all displaced toward the rear side (boundary side between the rack units). Sprinkler heads 22, 23 are provided. Further, a water supply pipe 21 is provided in a space where the small-diameter support 11 on the rear side of the rack unit 4 can be deflected to the front side. For this reason, the water pipe 2
As for 0 and 21, those having a thickness up to the diameter of the columns 8 to 11 can be used, and a thick water supply pipe can be used. If the water supply pipes 20 and 21 are made thicker, for example, even in a high-rise rack, the water supply capacity is increased, so that a large number of sprinkler heads 22 and 23 can be arranged.

The water supply pipe 20 and the sprinkler head 22,
Since the column 23 is disposed in a space in which the columns 8 and 10 are retracted rearward, no dead space occurs. Since the water supply pipe 21 is provided in a space in which the column 11 is deviated to the front side, no dead space occurs here. Further, since the diameter of the column 11 is smaller than that of the columns 9 on both sides, the protrusion of the column 9 on the front side of the column 11 from the front surface can be reduced or eliminated, and the shelf receiver 12 can be stably placed. Since the sprinkler heads 22 and 23 are disposed below the horizontal barrier 18 and the horizontal barrier 18 is also used as the water shield 26, no new dead space is generated.

The water supply pipes 20, 21 can be of any diameter within the range of the columns 8 to 11, and the water supply capacity can be increased by using a large-diameter water supply pipe, and a large number of sprinkler heads can be used even in a high-rise rack. Can be arranged. Each point of the rack is covered with a plurality of sprinkler heads. When a fire occurs, any one of the sprinkler heads operates.
Even if there is a delay in the time until the start of the operation of Step 25, the fire can be extinguished quickly.

Further, a water supply pipe 20 is disposed in front of the columns 8, 10, and a sprinkler head 22,
23, the sprinkler heads 22, 23
Can also be arranged in a space in which the columns 8, 10 are deflected rearward. This allows the water pipes to be placed directly on the columns,
Shadows can be minimized by the columns during watering, and there is no dead space not only for the water supply pipe but also for the sprinkler head. The water supply pipe 21 is disposed in a space in which the column 11 is deviated to the front side, the branch pipes 27 and 28 are disposed in an empty space originally existing such as a boundary between racks, and the water shield plate 26 is provided at a height from the shelf receiver 12. , So dead space hardly occurs.

Although the embodiment has shown a pair of racks arranged back to back, the embodiment may be applied to a single rack provided alone.
