DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to various racks in which each stage support section is divided into a plurality of load storage spaces in a rack length direction by a support frame.

[0002]

2. Description of the Related Art As a facility for storing loads loaded on pallets of the same size and various types of box pallets of the same size, as shown in FIGS. Each of the load supporting portions 2A to 2C is partitioned into a plurality of load storage spaces 3 in the rack length direction by the support frames 1 arranged at intervals, and one load 4 (FIG. 7A) or 2 is provided in each load storage space 3. Racks 5 and 6 that store two loads 4 (FIG. 7B) in parallel are known.

In the conventional racks 5 and 6 of this type, the upper end of each support frame 1 protrudes upward from a horizontal erection member (such as a shelf plate) 7 constituting the uppermost load support portion 2A. The load support portions 2A are also lower load support portions 2B and 2C.
Similarly, the storage efficiency of the entire rack is determined by the number of support frames 1 arranged in parallel when the number of stages of the load support portions is constant, since the load storage space 3 is divided into a plurality of load storage spaces 3 in the length direction of the rack as in the case of FIG. There was no way to improve storage efficiency.

Is placed on the middle trolley 18b. Thereafter, the load 15-3 is similarly placed on the lower carriage 18c, and the last load 15-4 can be placed on the guide rail means 17 after the lower carriage 18c has moved. .

As shown in FIGS. 1, 3 and 4, each of the support frames 12A to 12C has two support members 19a, 19a.
The three frame units 22a to 22c having a lattice girder structure in which the vicinity of both upper and lower ends of 9b are connected by a horizontal connecting member 20 and the middle portion is connected by an oblique reinforcing member 21 are connected by a horizontal connecting member 23. The upper ends of the support frames 12A and 12B have the uppermost load support portion 11.
A, and the upper end of each intermediate support frame 12C has the uppermost stage load support portion 1C.
The height is reduced so as to be at the same level as the upper surface of the horizontal installation member 14 of 1A. The guide rail means 17 of the bogie mechanism 16 is supported on the horizontal erection member 14.

In the rack 10 having the above-described configuration, the middle and lowermost load supporting portions 11B and 11C are divided into a plurality of load storage spaces 13 in the rack length direction by an intermediate support frame 12C, but the uppermost load supporting portion 11A. The number of the bogie mechanisms 16 arranged in the middle is changed to the middle and lowermost load supporting portions 11B,

The number P of the space 13 (the bogie mechanism 16
Is 6), the left side of the above equation (d + D) × (P
-1) becomes 875, and the right side of the above equation W + D = 110
Although smaller than 0, by setting the number P (the number of the bogie mechanisms 16 in parallel) of the load storage space 13 to 7, the left side (d + D) × (P−1) of the above equation becomes 1225, and the above equation becomes Is larger than W + D = 1100. In other words, as shown in FIG. 1, the middle and lowermost load support portions 11
By setting the number P (the number of paralleled bogie mechanisms 16) of the load storage spaces 13 in the rack length direction in B and 11C to 7, the number of parallel bogie mechanisms 16 in the rack length direction in the uppermost load support portion 11A is set. Can be increased by one to 8, and as shown in FIG.

The width D 'of the gap between the loads 15 placed on the sheet 6) can be ensured to be slightly wider than the minimum required gap of 100 mm.

The rack 10 shown in the above-described embodiment is a special one provided with a bogie mechanism 16 for storing a plurality of loads 15 in the depth direction of each of the stage load supporting portions 11A to 11C. The bogie mechanism 16 may be omitted from the rack 10 shown, and the rack 10 may be implemented as a general rack capable of storing only one load 15 in the depth direction of each of the stage load support portions 11A to 11C.

In the rack 10 shown in the above embodiment, one load 15 is placed in the load storage space 13 of the middle and lowermost load support portions 11B and 11C separated by the intermediate support frame 12C in the rack length direction. As shown in FIG. 6, the middle and lowermost load support portions 11B, 11B,
The present invention is applied to a rack 25 configured so that two (or two or more) loads 15 can be placed in parallel in the rack length direction in each load storage space 13 of 11C as shown in the drawings. Can be.

Also in this case, the above equation (d + D) × (P−

By setting the number P of 3, the uppermost load support portion 11
In A, one or more loads 15 can be stored in parallel with the number of loads stored in the rack length direction in the middle and bottom load supports 11B and 11C.

Specifically, the width d of the support frame is set to 100
mm, the width D of the gap to be secured between the support frame and the load
Is 100 mm and the width W of the load is 1000 mm, when the number P of the load storage spaces 13 in the rack length direction in the middle and lowermost load supporting portions 11B and 11C is 6, the left side (d + D) × ( P-1) is 1000, which is smaller than the right side W + D = 1100 of the above equation, but by setting the number P of the load storage space 13 to 7, the left side (d
+ D) × (P−1) becomes 1200, which is larger than the right side W + D = 1100 in the above equation. In other words, FIG.
As shown in the figure, the middle and lowermost load supporting portions 11B, 11B
C, the number P of the load storage spaces 13 in the rack length direction is 7
As a result, the middle and lowermost load supporting portions 11B,
The number of parallelly stored loads in the rack length direction at 11C is 14
On the other hand, the number of parallel storages in the rack length direction in the uppermost load support 11A can be increased by one to 15, and the adjacent loads 15 in the uppermost load support 11A can be increased. Can be secured slightly wider than the required minimum gap of 100 mm.

In the case of the rack 10 provided with the bogie mechanism 16 described above, the storage position of the load 15 by the bogie mechanisms 16 also in the uppermost load supporting portion 11A which is not partitioned by the intermediate support frame 12C. I can judge it clearly,
In the case of the rack 25 of the above-described embodiment, as shown in FIG. 6, on the front of the horizontal support member 14 between the support frames constituting the uppermost load support 11A, the uppermost load support 11A is provided. It is desirable to display the load support position indicating mark 26 corresponding to each load support position. The mark 26 may be formed by attaching a seal to a predetermined location on the front of the horizontal erection member 14, or by applying a paint or stamping a predetermined location on the front of the horizontal erection member 14. May be.

The racks that can be constructed according to the present invention are not limited to the racks 10 and 25 shown in the above two embodiments. For example, the present invention can be applied to a movable rack in which a work passage can be formed between adjacent racks by laterally moving on guide rails.

[0021]

As described above, according to the rack of the present invention,
The number of loads stored in the uppermost load support unit in the total load storage space in the rack length direction of the lower load support unit is one.
Since more than one can be supported, the storage efficiency of the entire rack can be improved. In particular, as shown in the embodiment, a rack capable of storing a plurality of loads in series in the depth direction of the load support portion can greatly increase the storage efficiency. Moreover, between each load stored in parallel in the topmost load support,
A gap equal to or wider than the gap that should be secured between the load and the support frame in the lower load support section can be reliably secured, so loading and unloading of the load to the uppermost load support section is also easy and safe. I can do it.

According to the second aspect of the present invention, even if the load supporting position cannot be specified using the intermediate support frame located right beside the load as an index, the load supporting portion at the uppermost stage cannot be specified. Since the load support position can be easily confirmed by using the support position indicating mark, loading and unloading of the load to and from the uppermost load support portion can be performed more safely and easily.
