[0004]

In the conventional frame shelf, the mounting position of the shelf receiver 27 is determined in advance according to the height of the load to be accommodated, and the support hole 21 is engaged with the engaging hole 29a corresponding to the position. , 29b are formed. Therefore, when the height of the load to be accommodated is changed, the shelf receiver 27 is adjusted accordingly.
In order to change the mounting position of No. 2, it is necessary to newly form the engaging holes 29a and 29b, and it takes much time to change the mounting position of the shelf receiver 27. Also, the engagement holes 29a,
Since 29b is formed in one vertical line, the engaging holes 29a, 29a
There is a problem that the pitch of b cannot be set to be less than the length of the engagement holes 29a and 29b, the mounting pitch of the cargo receiving rack 25 becomes larger, and the storage efficiency becomes lower.

The present invention has been made in view of the above problems, and an object of the present invention is to mount a cargo receiving rack at an arbitrary position and to mount the cargo receiving rack in response to a change in height of a load to be accommodated. It is an object of the present invention to provide a column for a frame shelf which can be easily changed in position and whose setting position of the load receiving shelf can be adjusted in units shorter than the length of the engaging hole.

[0006]

In order to achieve the above object, according to the present invention, a pillar connected by a brace and erected from the floor and a rack for receiving a load, which is locked to the pillar, are used for placing a load. In the frame shelf of the automatic warehouse, the engaging holes into which the locking portions projecting from the cargo receiving shelf are inserted are provided in a plurality of rows and with their pitches shifted over substantially the entire length.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment embodying the present invention will now be described with reference to FIGS.
It will be described with reference to FIG. As shown in FIGS. 1 and 2, the support column 1 includes a main body 2 in which a part of a square pipe is opened, and a pair of connecting plate portions 3 integrally formed so as to be continuous from the opening. It consists of The connecting plate portion 3 extends along a direction in which the side walls 2a and 2b of the main body 2 extend at a predetermined interval, and the tips thereof are bent outwardly to form a substantially inverted L-shaped cross section.

As shown in FIGS. 3 (a) and 3 (b), the main body 2
Vertically long engaging holes 4 are formed in two rows at a predetermined pitch P over the entire length of both side walls 2a, 2b. The engagement hole 4 is formed in a shape in which a circular portion 4b having a diameter larger than the width of the long hole 4a is continuous with the lower end of the long hole 4a. The engagement hole 4 is formed by punching.
The pitch P of the engagement holes 4 in each row is set to be smaller than twice the length of the engagement holes 4, and the engagement holes 4 in the adjacent rows are arranged such that the pitches P are deviated from each other by ½ pitch. ing.

The two rows of engaging holes 4 formed in the side walls 2a and 2b are located at positions opposite to each other, but the positions of the opposing engaging holes 4 are equal to ½ pitch. It is out of alignment. That is, the engagement holes 4 in the front row of the first side wall 2a
And the engaging holes 4 in the rear row of the second side wall 2b are formed at the same height position, and the engaging holes 4 in the rear row of the first side wall 2a and the second side
The side wall 2b is formed at the same height position as the front row engagement hole 4.

In addition, circular through holes 5 are formed at predetermined intervals in both connecting plate portions 3 at positions facing each other over substantially the entire length. The through holes 5 are not all the same, and every other through hole 5 has a recess 5a.

As shown in FIG. 1, the cargo receiving rack 6 attached to the support column 1 is formed in a rail shape having a substantially L-shaped cross section in which a rack bar 6a and a rack receiver 6b are integrally formed. Locking portions 7a, 7b that can be locked in the engaging holes 4 are integrally formed at the left and right ends of the shelf receiver 6b so as to project to the back side of the shelf receiver 6b. Both locking portions 7a, 7b are formed at the same pitch as the pitch P of the engagement holes 4. Also, the shelf receiver 6b
On both sides of the rivet hole 8 having the same diameter as the circular portion 4b of the engaging hole 4.
Is formed at a position at a distance equal to the row interval of the engagement holes 4 from the end of the shelf receiver 6b.

Next, the operation of the strut 1 constructed as described above will be described. When assembling the frame rack, as shown in FIG. 4, the columns 1 are erected with the connecting plate portions 3 thereof facing each other. Then, the load receiving shelves 6 are formed at the same height position formed on both columns 1 so that the cargo receiving shelves 6 are at a predetermined height position.
It is attached with the locking portions 7a and 7b inserted thereinto.
In this state, one of the rivet holes 8 formed in the shelf receiver 6b corresponds to the circular portion 4b of the engagement hole 4, and the rivet 9 penetrating the rivet hole 8 fixes the shelf receiver 6b to the column 1. To be done.

Further, as shown by a chain line in FIG. 2, the connecting plate portion 3
The end portion of the brace 10 is inserted between them, and the brace 10 is clamped and fixed by a rivet or the like penetrating the through hole 5. Although the brace 10 is fixed at a predetermined position between the supporting columns 1 facing each other, since the shapes of the through holes 5 are different every other one, it is easy to confirm the position of the through holes 5 to be connected and erroneous assembly is prevented.

Since the engagement hole 4 is formed over the entire length of the support column 1, the load receiving shelf 6 can be attached at an appropriate position without forming the engagement hole 4 in accordance with the height of the load. it can. When the engagement holes 4 are in one row, the mounting positions of the load receiving shelves 6 can be changed only by the pitch intervals of the engagement holes 4. or,
The size of the pitch P cannot be made smaller than the length of the engagement hole 4. However, since the engagement holes 4 are formed in two rows, the row of the engagement holes 4 that locks the locking portions 7a and 7b is changed so that the mounting position of the cargo receiving rack 6 can be changed. It can be changed at intervals smaller than the pitch P (1/2 pitch in this embodiment). Further, the pitch P of each row cannot be made smaller than the length of the engaging hole 4, but the pitch P of the engaging hole 4 is set to be smaller than twice the length of the engaging hole 4, so that the locking is performed. By alternately changing the rows of the engagement holes 4 that lock the portions 7a and 7b, the mounting position of the cargo receiving shelf 6 can be changed.
Can be changed in units smaller than the length of.

Further, since the engaging hole 4 of this embodiment is formed in a continuous shape of the elongated hole 4a and the circular portion 4b, the circular portion 4b can be used as a rivet hole. Therefore, the cargo receiving rack 6 can be fixed to the support pillar 1 via the rivets 9, so that the cargo receiving rack 6 can be more reliably fixed to the pillar 1. or,
Since the circular portion 4b can be used as a rivet hole, the engagement hole 4 that is not used for mounting the cargo receiving shelf 6 can be used as a mounting bracket for a safety net or another bracket provided on the rear side of the frame shelf. . Further, since the engagement hole 4 formed over substantially the entire length of the support column 1 is formed by punching, the weight of the support column 1 can be reduced.

When the engagement holes 4 are formed in two rows at symmetrical positions on both side walls 2, the engagement holes 4 in the front row or the engagement holes in the rear row have the same height. Therefore, as the load receiving shelves 6, the locking portions 7a and 7b are formed on the left and right sides at the intervals between the engagement holes 4 in the front row, and on the left and right sides at the intervals between the engagement holes 4 in the rear row. It is necessary to prepare two types, a tamono. However, in this embodiment, the engaging holes 4 of the columns 1 that are erected facing each other are formed such that the engaging holes 4 on the front row side and the engaging holes 4 on the rear row side are at the same height position. There is. Therefore, the locking portions 7a on the left and right sides,
The load receiving shelves 6 having the same interval 7b can be locked between any of the engaging holes 4.

The present invention is not limited to the above-described embodiment. For example, the circular portion 4b is located above each engaging hole 4, or the engaging hole 4 is simply a long hole. Good. Further, the engagement holes 4 may be arranged in three or more rows. In this case, the mounting position of the cargo receiving rack 6 can be adjusted in smaller units. Further, instead of forming the engaging holes 4 on both side walls 2a and 2b, they may be formed on the rear wall of the support column 1 as in the conventional case. In this case, the number of rows of engagement holes formed in the rear wall is 1
A number of types of cargo receiving shelves 6 corresponding to the number of / 2 are required.
Further, the engaging hole 4 may be formed by cutting and raising instead of punching, but if it is formed by cutting and raising, there is no merit of weight reduction. Further, the cargo receiving shelf 6 attached to the support 1 may have a structure in which the shelf bars 6a and the shelf receiver 6b are formed separately.

[0019]

As described above in detail, according to the present invention, the loading rack can be mounted at an arbitrary position, and the loading position of the loading rack can be easily changed in accordance with the height of the load to be accommodated. Therefore, it is possible to mount the load receiving shelves in correspondence with an arbitrary load height, instead of using it as a dedicated column corresponding to the height of the load to be accommodated in advance. Also, since the setting of the mounting position of the load receiving shelf can be adjusted in units shorter than the length of the engagement hole, when the storage efficiency is improved and the same amount of load is to be stored, the height of the entire frame shelf is lowered. As a result, space can be saved.
