Description

  The present invention relates to a rack used in an automatic warehouse or the like.

  The applicant has proposed a structure for installing a sprinkler in an automatic warehouse (Patent Document 1). In Patent Document 1, a pair of rack units are arranged back to back, a vertical tube or a horizontal tube of a sprinkler is installed at a boundary portion between the rack units, and water is supplied to the sprinkler head by the horizontal tube. However, in reality, a structural material such as a brace is disposed at the boundary between the pair of rack units. Therefore, in order to prevent interference with the structural material, the water supply pipe is disposed close to one of the rack units.

In the rack unit on the side where the water supply pipes are arranged close to each other, the depth for housing the articles is insufficient. This is because the horizontal pipe interferes with the article and the crane fork, and therefore the article cannot be accommodated to the farthest part of the rack unit. Therefore, the rack unit on the side where the water supply pipes are provided is extended to the passage side, and the depth for accommodating articles in the pair of rack units is made uniform. However, if the rack unit on the side where the water supply pipe is provided is extended to the passage side, the arrangement of the columns is different between the pair of rack units, making it difficult to assemble the rack. Here, the boundary between the rack units is called a back side or a rear side, and the direction opposite to the back side in the depth direction is called a front side or a passage side.

An object of the present invention is to make the arrangement of the columns symmetrical between the pair of rack units while providing a horizontal pipe for supplying water to the sprinkler.
An additional object of the present invention is to be able to provide both a brace for reinforcing the rack and a horizontal tube.
An additional problem in the invention of claim 2 is to enable easy installation of a vertical pipe for water supply to the sprinkler.

The present invention is a rack in which a pair of rack units are provided with shelf supports spanned between the front and rear columns, and the pair of rack units are coupled back to back on the back side,
Arrange the front and rear columns of each rack unit symmetrically between a pair of rack units,
A lateral pipe for supplying water to the sprinkler head is provided between the rack unit and the rack unit closer to one rack unit than the center of the boundary between the pair of rack units, and
A brace is provided between the rack unit and the rack unit, and the horizontal pipe is arranged closer to the one rack unit than the brace,
The shape of the shelf holder is different between the one rack unit and the other rack unit,
The rack unit front end of the one rack unit protrudes forward from the rack rack front end of the other rack unit, and protrudes forward from the front column of the one rack unit. The rear end of the shelf is retracted from the horizontal tube.

Particularly preferably, the rear column of the pair of rack units is configured by two types of columns, a first column near the boundary between the rack units and a second column that is separated from the boundary. The first support and the first support are opposed to each other, the second support and the second support are facing each other,
A vertical tube for supplying water to the horizontal tube is provided between the second column and the second column.

  According to the present invention, it is possible to lay water supply piping to the sprinkler head while maintaining the same column arrangement in the pair of rack units. And in the rack unit on the side where the horizontal pipe for supplying water to the sprinkler is arranged, the shelf holder protrudes forward from the front column of the rack unit, so the depth of the shelf holder is almost the same as the other rack unit. it can. In the present invention, the shape of the shelf holder differs between the pair of rack units. However, since the shelf receiver is manufactured in a larger number than the rack unit, the influence on the cost of the rack is small.

Here, it provided with a breath between the rack unit and the rack unit, since the arranged close next tube to one of the rack units than breath, to obtain both a space for the arrangement space and horizontal tube of breath it can.
Further, the rear column of the pair of rack units is composed of two types of columns, a first column near the boundary between the rack units and a second column separated from the boundary. The second struts are alternately arranged so that the first struts and the first struts face each other, the second struts and the second struts face each other, and the second struts and the second struts When a vertical pipe for supplying water to the horizontal pipe is provided between the vertical pillars, a space for arranging the vertical pipes can be obtained by utilizing the space between the second pillar and the second pillar pipe having a large interval.

  In the following, an optimum embodiment for carrying out the present invention will be shown.

  The rack 2 of an Example is shown in FIGS. The rack 2 includes a pair of rack units 4 and 6, and these rack units 4 and 6 are coupled to each other on the rear side, in other words, on the back side. Reference numeral 8 denotes a support column on the front side of the rack units 4 and 6, and a large-diameter support column 9 and a support column 10 having a smaller diameter than the support column 9 are alternately arranged on the back side. The struts 9 and 9 are faced to each other and joined by a metal fitting 28, and the pillars 10 and 10 are faced to each other so as to leave a space between them, and the vertical tube 16 is placed in this space. For example, the rack 2 may be used as a part of an automatic warehouse, and a plurality of racks 2 may be arranged in parallel in the automatic warehouse.

  12 and 14 are shelf supports, and the front end of the shelf support 12 is at a position equal to the front end of the support column 8, and the front end of the shelf support 14 is at a position protruding forward from the front end of the support column 8, in other words, forward. A line connecting the front ends of the shelf supports 14 is shown as a shelf reception front end line F1, and a line connecting the front ends of the shelf supports 12 is shown as a shelf reception front end line F2. The arrangement of the columns 8 to 10 is common to the rack units 4 and 6 and is symmetrical with respect to the boundary between the rack units 4 and 6. The shelf receiver 14 and the shelf receiver 12 are different in shape.

  A vertical main pipe (longitudinal pipe in the claims) 16 and a horizontal branch pipe (horizontal pipe in the claims) 18 are provided at the boundary between the rack units 4 and 6. A branch pipe 20 is further connected to the branch pipe 18 to supply water to the sprinkler head 22. For example, the sprinkler head 22 is provided for every several stages of the rack units 4 and 6, and the branch pipes 18 and 20 are provided on the stage where the sprinkler head 22 is provided. Here, the steps indicate the height positions of the rack units 4 and 6 and are counted in units of the shelf holders 12 and 14. The main pipe 16 is provided in the space between the supporting columns 10 and 10 facing each other, and is closer to the rack unit 4 side than the boundary between the rack units 4 and 6. The main pipe 16 supplies water to the four sprinkler heads 22 in a plan view, and the main pipe 16 is provided for every eight front doors in a plan view. Can be placed. The branch pipe 18 is also arranged closer to the rack unit 4 side than the boundary between the rack units 4 and 6.

  Reference numeral 24 denotes a vertical surface brace, which is arranged from the center of the boundary between the rack units 4 and 6 to the rack unit 6. The metal fixtures 26 to 28 are attached to the columns 8 to 10, and the vertical construction surface brace 24, the horizontal connecting material 30, the horizontal construction surface brace 32 and the like are attached. Since there is a vertical surface brace 24 at the boundary between the rack units 4 and 6, the branch pipe 18 is arranged close to the rack unit 4 side in order to avoid this.

  2 shows the rack 2 as viewed from the front end side of the shelf holder 14, and FIG. 3 shows the rack 2 as viewed from the side. In FIG. 3, vertical braces at both ends in the longitudinal direction of the rack 2 are omitted. The struts 8 and 10 and the main pipe 16 have, for example, substantially the same diameter, and the branch pipe 18 and the branch pipe 20 (not shown) are arranged above the horizontal connecting material 30. Since the height position of the branch pipe 18 overlaps with the position where the slide fork of the stacker crane moves forward and backward, the front end of the shelf holder 14 is advanced to the front side of the front end of the shelf holder 12 to eliminate interference between the branch pipe 18 and the slide fork. To do. The arrangement of the columns 8 to 10 is common between the rack units 4 and 6. As a result, the arrangement of the columns 8 to 10 can be made symmetrical with respect to the boundary between the rack units 4 and 6. As a result, the rack units 4 and 6 can be easily assembled. Further, a stopper 34 shown in the lower left of FIG. 3 may be provided at the front ends of the shelf supports 12 and 14 so that the article does not advance further to the passage side than the stopper 34.

  The difference between the rack units 4 and 6 is that the main pipe 16 and the branch pipe 18 are arranged close to the rack unit 4, and accordingly, the shelf receiver 14 is advanced to the passage side from the front end of the column 8. And the shape of the shelf receiver 14 is different from that of the shelf receiver 12. However, since the shelf supports 12 and 14 are members that are manufactured in large quantities per rack unit 4 and 6, even if the shape of the shelf supports 14 and 12 is different, the influence on the manufacturing cost is small.

  The branch pipe 18 occupies the space near the back surface of the rack unit 4, but the shelf holder 14 has advanced from the front surface of the support column 8, so the space in the depth direction is common between the rack units 4 and 6. It is also conceivable that the front end of the shelf receiver 14 ends at the same position as the front end of the support column 8 and an article such as a pallet is accommodated so as to protrude beyond the front end of the shelf holder 14. Since a large force acts at the boundary between the position supported by the shelf receiver 14 and the position not supported by the shelf receiver 14 without being supported by the receiver 14, the article is easily damaged.

In the embodiment, the following effects can be obtained.
(1) The main pipe 16 and the branch pipe 18 can be arranged at the boundary part on the back side of the rack units 4 and 6.
(2) The main pipe 16 can be arranged using the gap between the columns 10 and 10.
(3) Since the branch pipe 18 is moved to the rack unit 4 side, both the branch pipe 18 and the brace 24 can be provided.
(4) Although the branch pipes 18 are arranged close to the rack unit 4 side, the arrangement of the columns 8 to 10 is symmetrical between the rack units 4 and 6.
(5) Since the front end of the shelf receiver 14 is advanced to the passage side from the support column 8, the depth and the crane fork space for storing articles in the rack units 4 and 6 are common.
