DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a column forming a shelf in an automatic warehouse.

[0002]

2. Description of the Related Art Conventionally, shelves of an automatic warehouse are divided in a continuous direction by columns that are erected from the floor at regular intervals, and are divided in a stepwise direction by shelves provided between the columns. A shelf for storing the pallets is formed in a space surrounded by the shelves. The columns, which are the main members forming the shelves, have the same width from the base to the upper end, and the spacing between the columns and the pallets is the same for both the shelves below and above the columns.

[0003]

The struts used in the above-mentioned conventional automatic warehouse have the same width from the base to the upper end, so that the struts are heavy and use of raw materials such as steel used for the struts is high. The volume was large and heavy, causing an increase in product cost. During operation, the stacker crane may cause a slight inclination of the floor on which the rails of the crane are laid, unevenness in brake braking, verticality of the crane, and swinging of the upper part of the crane when stopped. In order to safely and securely insert and remove the pallet from the shelf, the distance between the support and the pallet should be set based on the shelf above the support, and the above-mentioned interval on the shelf below the support should be unnecessarily wide. Had become.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and is intended for an automatic warehouse which is lighter in weight than a conventional device, has a narrow pitch interval between columns, and can insert and remove a pallet safely and securely. A shelf for an automatic warehouse, which provides shelves, in which a continuous direction is divided by a plurality of columns standing upright from the floor surface, and a section divided in a stepwise direction by a shelf material provided between the columns is provided. , The support is gradually narrowed from the base toward the upper part, and the distance between the support and the pallet is larger at the support upper part than at the support base.

[0005]

According to the present invention, the columns for dividing the connecting direction of the shelves are gradually narrowed from the base to the upper portion, and the interval between the columns and the pallet is made larger at the column upper portion than the column base. In the case where the column is erected in the width of the continuous direction, the distance between the column and the pallet at the top of the column is larger than that of the conventional shelf. It is possible to prevent troubles that occur when a pallet is inserted into and removed from a shelf.

In the case where the width between the pallet and the column at the upper portion of the column is the same as the conventional one, the continuous pitch width between the columns can be reduced as compared with the conventional apparatus, and the length in the same continuous direction can be reduced. Therefore, many shelves can be provided, and the warehouse space can be used more efficiently. Furthermore, by reducing the continuous pitch width, the horizontal beams, horizontal braces, and rear braces are shortened, and the weight of the entire rack can be reduced.In particular, a house type in which a roof and walls are attached to shelves to form an automated warehouse In the case of (1), if the pitch is small, the equipment itself including the roof, walls and foundation can be downsized, and the cost can be greatly reduced.

[0007]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a side view schematically showing the entirety of an automatic warehouse according to the present invention, and FIG. 2 is an enlarged view of a connecting portion of the pillar, which is a main part of the present invention, in which a pillar is gradually narrowed from a base to an upper part. It is a front view.

The automatic warehouse shown in FIG. 1 is laid horizontally on a plurality of columns 1 standing vertically , a step is formed by a shelf 2 supporting the lower surface of the pallet, and a column is formed by the columns 1. And a stacker crane 5 that moves along the front surface of the rack body 4. The rack body 4 is a stacker crane 5 as described above.
And a shelf 2 laterally provided between the columns 1, and a space surrounded by the two forms a shelf 3. Furthermore,
Each of the columns 1 includes a horizontal beam 9, a horizontal brace 10, and a back brace 11 provided outside the rack body 4, which are provided at predetermined intervals in the vertical direction in the horizontal direction, thereby maintaining the rigidity of the rack body 4. Dripping.

As shown in FIG. 2, the shelf 3 of the present invention has a structure in which the columns 1 are gradually narrowed upward from the base, and 7 is a connection for fixing the upper and lower columns. Department. FIG. 2 shows an embodiment of the pillar according to the present invention in which the continuous pitch interval a of the pillar is 1285 mm and the pallet width b is 1000 mm. The pillar width C ₁ of the lower pillar _{1 a} is 175 mm with the connecting part 7 of the pillar as a boundary. whereas, strut width C ₂ of the upper strut 1b connected thereto is 125 mm.

In this embodiment, the distance d ₁ between the support and the pallet 8 in the lower support 1a is 55 mm on both the left and right sides, while the distance d ₂ in the upper support 1b connected thereto is 80 mm. In the shelf of the column 1b, the distance between the column and the pallet can be increased by 25 mm as compared with the shelf of the lower column. In this way, by gradually narrowing the width of the column from the base to the top of the column, the distance between the column and the pallet can be set large above the column 1, and the stacker crane can swing. Even when movement occurs, the pallet can be easily inserted into and removed from the shelf from the upper stacker crane.

[0011]

According to the present invention, the columns for dividing the connecting direction of the shelves are gradually narrowed from the base to the upper part,
By increasing the distance between the support and the pallet at the upper part of the support from the base of the support, when the support is erected with the width in the continuous direction as before, the distance between the support and the pallet at the upper part of the support is It is larger than a shelf and can prevent troubles that occur when a pallet is inserted into and removed from the shelf due to the swinging of the upper part of the crane in the front-back direction as in the conventional apparatus.

In the case where the width between the pallet and the column at the upper portion of the column is the same as the conventional one, the continuous pitch width between the columns can be reduced as compared with the conventional device, and the length in the same continuous direction can be reduced. Therefore, many shelves can be provided, and the warehouse space can be used more efficiently. Furthermore, by reducing the continuous pitch width, the horizontal beams, horizontal braces, and rear braces can be shortened, and the weight of the entire rack can be reduced.In particular, in the case of a house type, if the continuous pitch is reduced, the roof, The equipment itself, including walls and foundations, can be miniaturized and significant cost reductions are possible.

Further, according to the present invention, since the amount of materials such as steel used for the columns is reduced as compared with the conventional apparatus, the cost of the apparatus can be reduced.
