Link. Thus, the assembly of the pallet storage shelf A is completed.

When using the pallet storage shelf A,
As shown in FIG. 4, by connecting the connecting column of the lower frame 1 of the upper pallet storage shelf to the connecting column of the upper frame 3 of the lower pallet storing shelf, the pallet is stored in a storage space such as a warehouse in advance. The shelves A1, A2, A3,... Are assembled in stages. Then, when storing the luggage, the pallet 27 may be lifted by a forklift (not shown) while the luggage 30 is loaded, and placed on the upper frame 3 of each storage shelf. Pallet 2 in this case
7 preferably utilizes a pallet of normal construction.

When the pallet storage shelf is not used, FIG.
, The pallet storage shelves A1, A2, A3,... Can be stacked. In this case, the upper storage shelf A
The lower ends of the connecting pillars 6a at the front ends of 2, A3, A4... Are fitted to the pins 11 of the receiving seats 10 at the front ends of the lower storage shelves A1, A2, A3. To

Therefore, a large number of storage shelves can be stored in a small space. In addition, since the brace 4 serves as a guide during the stacking operation, the operation is easy.

Next, when the pallet storage shelf A is used,
It is also possible to assemble the pallet 5 in advance on the pallet storage shelf. At this time, as shown in FIGS. 2 and 6, the shaft 25 at the rear end of the side frame 24 of the pallet 5 is attached to the lower frame 1.
Into the shaft hole 15 of the rear connecting column 6b, and through the screw holes 23 of the side plates 22 at both ends of the front frame of the pallet 5,
1 may be screwed into the screw hole 14 of the front connection column 6a of the lower frame 1. Then, the package is transported with the storage shelf A fixed to the pallet 5. Also, when storing the luggage, it is sufficient to stack the storage shelves as shown in FIG.

Also in this case, it is also possible to assemble in advance as shown in FIG. 7 and to use the pallet on the assembled pallet 5 with the load placed on a normal pallet. .

As described above, the lower frame 1, the upper frame 3, and the column 2 are formed independently of each other, and the column 2, the lower frame 1, and the upper frame 3, and the upper frame 3, the lower frame 1, and the brace 4 and 4 are each configured to be detachable, so that assembly and disassembly are possible. Therefore, by replacing the pillar main body 2a and the brace 4 for the same lower frame 1 and upper frame 3, the height of the storage shelf can be freely changed according to the size of the load placed on the pallet 5. Can be adjusted.

By extending the column sub-body 2c with respect to the column main body 2a, it is possible to freely variably adjust the height of the storage shelf in accordance with the size of the load placed on the pallet 5 as described above. it can.

Also, the brace 4 is disposed on the side and the back, so that the strength is reinforced and the brace 4 prevents the load from shaking during transportation, so that the load falls off or collapses. Can be effectively prevented.

Further, since the number of constituent members is minimized, the assembling property is good, and the possibility that some parts are lost due to too many parts is very small.

In addition, two of the four columns 2 at the front are arranged on the front end of the side frame 1a of the lower frame 1, and the two at the rear are arranged on the rear frame 1b of the lower frame 1, respectively. Since the interval between the columns 2 is narrow, when inserting a normal pallet into the pallet storage shelf, the position of the pallet is determined by the position where the rear end hits the rear column 2.
Since the rear support 2 serves as a guide for mounting the pallet, workability and safety are enhanced.

A pallet 5 is provided inside the lower frame 1.
The storage system can be detached so that the storage shelves can be stacked on the storage space, and the luggage can be loaded on the pallet 5 and stacked on the storage shelves. It is also possible to adopt a storage method of the pallets 5 with storage shelves, in which the pallet 5 is fixed and the transportation of the load and the assembly of the storage shelves are performed simultaneously. Therefore, an optimal storage method can be appropriately and efficiently adopted according to the conditions such as the type of the package and the transportation, and the both methods can be combined.

Further, since the casters 33 are attached to the lower portions near the four corners of the pallet 5, the removal of the pallet 5 can be easily performed when the pallet 5 is moved to a predetermined place.

The column 2 is composed of connecting columns 6a, 6b, 17a, 17b provided on the upper and lower frames 1, 3, a column main body 2a and a column sub-body 2c fitted and connected to these columns. Since the connecting columns are firmly fixed to the upper and lower frames by welding, the overall strength is large. The support column 2 having such a split configuration is inferior in bending strength to a single support column. However, in the case of a storage shelf, the support column is required to have a strength to support the load of the upper storage shelf in the case of a column structure. There is no problem because strength is not so required. On the other hand, in the case of a column configured as a single body, the upper and lower ends are directly fixed to the upper and lower frames by fixing means such as bolts and screws, so that the fixing means is easy to loosen during transportation, etc. Shelving occurs on the shelves and must be retightened each time, and the durability is not good.

[0033]

According to the first aspect of the present invention, since the pallet is detachable from the pallet, a storage method of separating the pallet from the storage shelf can be adopted, May be adopted in a storage shelf, and the storage system is configured integrally with the storage shelf. Therefore,
Optimal combinations are possible according to the type of luggage and the conditions of transportation and storage.

Further, since the support, the lower frame, the upper frame, and the brace constituting the storage shelf are detachable, they can be assembled and disassembled, and the frames constituting the storage shelf can be rearranged. It can be adjusted according to the size.

In addition, in a state where the pallet storage shelf A is assembled, the columns can be extended in the same manner as described above by extending the columns.

Further, the brace is arranged on the side and the back, so that the strength is reinforced and the brace prevents the load from swaying at the time of transportation, so that the load is prevented from dropping or being collapsed. It can be effectively prevented.

According to the second aspect of the present invention, two of the four pillars at the front are arranged on the front end of the side frame of the lower frame, and the two at the rear are arranged on the rear frame of the lower frame. I have. In this way, the interval between the rear supports is narrow, so when inserting the pallet when mounting the pallet, the position of the pallet is determined by the position where the rear end hits the rear support, so the rear support is Since it serves as a guide for pallet installation, workability and safety are enhanced.

Further, since a plurality of storage shelves can be nested with the pallet removed, many storage shelves can be stored in a small space when not in use. In addition, since the brace serves as a guide during the nesting operation, the operation is easy.

According to the third aspect of the present invention, since the pallet is detachable from the pallet, it is possible to adopt a storage system in which the pallet is separated from the storage shelf, and the pallet is mounted on the storage shelf to be integrated. A structured storage scheme may be employed. Therefore, an optimal combination can be made according to the type of the package and the conditions of transportation and storage.
