Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automatic warehouse rack in which a large number of sprinkler heads are provided.

[0002]

2. Description of the Related Art Heretofore, a set of front and rear columns, a brace attached to each column so as to protrude left and right, and a shelf support for connecting between ends of the front and back brace are formed as one unit. An automatic warehouse consisting of a rack consisting of multiple units connected in the vertical and horizontal directions, and a stacker crane equipped with a slide fork that travels and raises and lowers in front of the rack and puts articles into and out of each frontage of the rack. Are known. In such an automatic warehouse, as a means for automatically extinguishing a fire generated in the warehouse, a large number of sprinkler heads are arranged in a rack, and a water supply pipe for supplying water to the sprinkler head. Are piped along the members constituting the rack. In order to minimize the dead space caused by the piping, a water supply pipe has been vertically arranged between the front and rear struts and beside the lattice.

[0003]

However, in order to completely eliminate the dead space caused by piping of the water supply pipe, even if the lattice is completely eccentric from the center of the column, the width of the lattice cannot be reduced from the width of the column. It is necessary to put the water supply pipe within the dimension from which the water supply pipe has been subtracted, and there has been a problem that a water supply pipe having a large diameter cannot be used. The number of sprinkler heads that can be attached to one water supply pipe is specified for each diameter of the water supply pipe (of course, the smaller the diameter, the smaller the number of sprinkler heads that can be attached becomes smaller) and arranged. When the number of sprinkler heads increases, it becomes necessary to provide a plurality of water supply pipes between a pair of columns, and there is a problem that piping work becomes complicated.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-described problems. According to the first aspect of the present invention, there is provided a front and rear support, and a brace projecting left and right from the front and rear support. And a shelf support for connecting between the ends of the front and rear arms, and extending at least one end of the shelf support so that its end face is located outside the outer surface of the column, and a shelf support on the side where the shelf support is extended. A water supply pipe was provided vertically outside the support, a sprinkler head was provided between the front and rear support, and a branch pipe from the water supply pipe to the sprinkler head was piped inside the shelf support.
According to the invention of claim 2, the sprinkler head communicating with the branch pipe and the collecting member located above the sprinkler head are located between the front and rear struts and between the left and right shelf supports and within the height range of the shelf supports. A hot plate was provided. Furthermore, in the invention of claim 3, at least one of the shelf supports is formed of C-shaped steel, the opening thereof is directed toward the support, and the branch pipe is formed of C-shaped steel.
It was put in and out of the opening inside the steel shape.

[0005]

According to the first aspect of the present invention, the amount of protrusion of the shelf support extending so that the end face is located outside of the outer surface of the column,
A piping space for the water supply pipe is formed outside the support column. If the water supply pipe has a diameter that does not exceed the width of the support, the pipe can be provided without generating dead space. In addition, since the branch pipe is piped inside the shelf support, dead space does not occur even with the pipe of the branch pipe. According to the second aspect of the present invention, no dead space is generated in any of the front-rear direction, the left-right direction, and the height direction even when the sprinkler head and the heat collecting plate are provided. Further, according to the third aspect of the present invention, no special processing is required for the shelf support because the branch pipe is provided inside the shelf support.

[0006]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to the embodiments shown in the drawings. In FIG. 5, the right side is the front, the left side is the rear, the upper side is the left, and the lower side is the right.

Each unit 10 includes a pair of front and rear columns 1A and 1B separated by a predetermined distance, arms 2A and 2B protruding left and right from the front and rear columns 1A and 1B, and front and rear arms 2A and 2B.
And shelf supports 3A and 3B connecting end portions of the shelf. One ends of the shelf supports 3A and 3B are extended so that their end faces are located outside the outer surface of the support 1A, and a space S for piping the water supply pipe 4 is formed. And
A water supply pipe 4 is provided outside the support 1A, which is the piping space S.
Are arranged in the vertical direction.

It is preferable that the amount of protrusion of the end faces of the shelf supports 3A and 3B from the outer surface of the column 1A is larger than the width of the column 1A. By doing so, the water supply pipe 4 having a diameter not exceeding the width of the column 1A can be installed without any dead space in the front-rear direction and the left-right direction. In other words, the water supply pipe 4 having a large diameter, which is substantially equal to the width of the support 1A.
Can be used, and a plurality of sprinkler heads 7 can be attached to one water supply pipe 4.

A plurality of vertical portions are also connected by lattices 5 between the front and rear columns 1A and 1B. This lattice 5
And the mounting position with respect to the support 1A, 1B center,
There is no restriction as long as it does not protrude from the columns 1A and 1B.

A branch pipe 6 is connected to the water supply pipe 4 at the same height as the shelf supports 3A and 3B. Shelf holder 3
A and 3B are made of C-shaped steel, and the opening 9 of the column 1 is
They are arranged so as to face the A and 1B sides. Therefore,
The branch pipe 6 can be inserted into the shelf receiver 3A from the opening 9 and is piped into the shelf receiver 3A. The free end of the branch pipe 6 is pulled out from the opening 9 at a substantially middle portion in the longitudinal direction of the shelf receiver 3A, and is piped such that its free end is located at a substantially middle portion between the left and right shelf receivers 3A and 3B. Sprinkler head 7
Is attached. Above the sprinkler head 7, a heat collecting plate 8 is attached. The sprinkler head 7 and the heat collecting plate 8 are connected to the front and rear struts 1 in plan view.
A and 1B, and between the left and right shelf supports 3A and 3B, and are arranged within the height range of the shelf supports 3A and 3B. Therefore, the front-back direction, the left-right direction,
The dead space does not occur in any of the height direction. In the case where the C-shaped steel is not used for the shelf supports 3A and 3B, an opening may be formed at the position where the branch pipe 6 is taken in and out. The heat collecting plate 8 may have a generally rectangular shape in addition to a rectangular shape in a plan view.

A rack R using such a unit 10
Will be described. Each unit 10 has a pair of columns 1A and 1B, a pair of arms 2A and 2
B, shelf supports 3A, 3B, water supply pipe 4, lattice 5, branch pipe 6,
It is assembled by integrating the sprinkler head 7 and the heat collecting plate 8 and transported to the installation site together with the horizontal tie 20 and the like.

At the installation site, a large number of units 10 are arranged side by side at a predetermined pitch, and the units 10 are connected to each other by a horizontal connecting member 20 or the like, thereby constructing a rack R of a desired scale. Note that the units 10 can be connected in the height direction as necessary.

The water supply pipe 4 of each unit 10 is connected at its lower end to a main water supply pipe 30 connected to a water supply source (not shown). This connection operation can be easily performed using a joint (not shown) or the like.

The rack R thus constructed and the rack R
One automatic warehouse is constituted by the stacker crane C which travels along the passage formed between the racks and puts articles into and out of each shelf of the rack R, and such an automatic warehouse is arranged such that the rear surfaces of the racks R are adjacent to each other. A single automatic warehouse system is constructed by arranging a plurality of units in parallel. Since a water supply pipe is not piped to the abutting portion on the rear surface of the rack R, a dead space does not occur between the rear surfaces, and a compact system can be provided. Further, since the water supply pipe 4 is provided on the side of the passage of the stacker crane C, the work of connecting the water supply pipe 4 and the like can be easily performed using this passage.

In this automatic warehouse system, if a fire occurs in the warehouse, the sprinkler head 7 located below the heat collecting plate 8 close to the fire source is opened due to the rise in ambient temperature, and the water supply pipe is opened. The water supplied to the branch pipe 6 via 4 is sprinkled.

[0016]

According to the first aspect of the present invention, a pipe space for a water supply pipe is formed outside the support column by an amount corresponding to the amount of protrusion of the shelf support extending so that the end face is located outside the outer surface of the support column. By arranging the water supply pipe in this space, the water supply pipe can be laid without generating a dead space. Also, as long as the diameter of the water supply pipe does not exceed the width of the column, there is no dead space, and a large-diameter water supply pipe can be used, thus reducing the number of water supply pipes and reducing piping work. It can be done more easily. Further, since the branch pipe is provided inside the shelf support, dead space does not occur even when the branch pipe is provided.
According to the second aspect of the present invention, the arrangement of the sprinkler head and the heat collecting plate also enables the front-rear direction, the left-right direction,
There is no dead space in both the height direction and the height direction, and a more compact rack can be provided. Further, according to the third aspect of the present invention, since a branch pipe is provided inside the shelf support, no special processing is required for the shelf support.
Racks can be easily manufactured.
