Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a mobile shelving device that efficiently utilizes the floor space in a building in which a plurality of pillars are erected.

[Prior art]

By stacking movable shelves with a large number of storage shelves with their storage surfaces facing each other when storing items, and by moving the movable shelves only when taking out and taking out items to form a work path, it is possible to store items inside the building. Mobile shelving devices are widely used to increase storage efficiency.

However, when pillars that interfere with the movable shelves are arranged side by side in the moving direction on the floor of a building in which such a movable shelf device is installed, the movable shelves are arranged using only the floor surface between the columns. was.

[Problem that the invention seeks to solve]

As a result, in addition to not being able to use the floor space of the total width of the pillars, it is also necessary to form a working passage between each pillar, resulting in poor floor usage efficiency. On a floor with such pillars, the utilization efficiency was about 50%, a relatively low value.

The present invention provides a movable shelf that includes a plurality of first movable shelves disposed between the columns and a second movable shelf of a small length provided near the columns, thereby making it possible to avoid the dead space conventionally created by the columns. The purpose of the present invention is to provide a movable shelf device that can be used to attach a movable shelf, increase the efficiency of floor space utilization, and solve the above-mentioned problems.

The cargo shelf 5 as a whole can also be loaded into and taken out of the cargo handling cart 2.

[Effect]

The movable shelf 11 illustrated in FIGS. 1(A), (B), and FIG. 2
A gap is provided between the housing surfaces aSb of B and 11C to form a working passage l.
0, the cargo handling cart 2 moves the transverse frame 113 of the transfer tool 4 on the guide plate 112 to the side opposite to the storage shelf 25 to be loaded and unloaded, and then moves the cargo handling cart 2 to the rotation drive 513.
1, the fork 119 is rotated via the rear frame 114 to a position facing the storage shelf 25. Also mast 11
After the height is adjusted to a predetermined storage shelf 25 by 0 extension, the puncture mechanism 115 is activated to store and store the article. In addition, the fork 119 can be positioned toward the storage shelf by a reverse action, and the puncture mechanism 115 can be used to move the fork into and out of the storage shelf. After the predetermined work, the cargo handling cart 2 moves to the rail 101.
It moves vertically over the rail 103, straddles the rail 103, and stops at a position where the second wheel 9 is aligned with the rail 103.

In this state, the elevating means 19 is operated to ground the second wheels 19 on the rails 103.

Thereafter, the first wheel 8 is lifted up using the lifting means 18 as described above. Therefore, the cargo handling cart 2 can traverse on the rail 103 to the next rail 101 position or to the loading/unloading platform 15. Articles can be taken in and out of the warehouse 15 as described above.

Next, when forming the working passage 10A between the column C2 and the movable shelf 11A, the connecting device 13 therebetween is released as described above. Also, two movable shelves 1 connected with a connecting device 13
Move 1A and IIB as one. Therefore, the width can be increased by connecting, and the height can be reduced relative to the width.
The elastic material 40 of the coupling device 13 prevents the movable shelf from collapsing and the articles from falling due to vibrations during movement or earthquakes occurring during movement.
Combined with the buffering effect of Furthermore, when the movable shelves 1--, which move as one, pass through the work passage 10 and face the accommodation surface a of the movable shelf 11G, the coupling device 13 is automatically coupled.

Furthermore, when forming the working passage 10B between the second and third movable shelves 11ASIIB, the movable shelves 11A and IIB are moved as one body, connected to the movable shelf 11C, and then moved backwards as one body. , drives only IIC.

Further, by integrally moving the first movable shelves 11A, IIB, and the second movable shelf 12B, a working passage 10C can be formed on the left side of the column C2.

FIG. 7 shows another example of the cargo handling truck 2, in which pilot seats 3A and 3B are provided on both sides of the vehicle body 3, and solid tires are used for the first and second wheels 8.9. Such a cargo handling cart 2 can be suitably used when the upper surface of the rail 23 for traveling the movable shelf 1 is buried flush with the floor surface F.

Furthermore, when the earthquake detector 16 detects an earthquake, it stops the movement of the movable shelf 1 and the fence cart 6 in advance, and when it detects an earthquake while it is moving, it stops it in a relatively short time without producing an impact.
