Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a three-dimensional warehouse for storing rolling rolls.

[Conventional technology and its problems]

The rolling rolls used in rolling mills are removed after a certain amount of use and their surfaces are polished. Such surface polishing must be carried out in a state where the temperature distribution of the roll is uniform, and for this reason, the rolling roll is uniformly cooled after being removed from the rolling mill. Conventionally, rolling rolls weighing 5 to 10 tons have been kept flat in a factory, and for this reason they are placed in a cooling tank 13 as shown in Figure 4.
is provided to uniformly cool the rolling rolls X. That is, the rolling roll X removed from the rolling mill is handled from the roll stand 14 by an overhead crane and loaded into the cooling tank 13, where the roll is uniformly cooled by being sprayed with water from the spray 15, and after treatment, it is handled by the overhead crane again. The rolling roll X is lifted up, transported to a predetermined roll mounting table 16, and kept on standby for polishing.

However, in such a conventional method, the work to take the product into and out of the cooling tank is extremely complicated, and in addition, it requires a large cooling space within the factory.

In view of these conventional difficulties, the present invention aims to provide a warehouse for storing rolls that can rationally uniformly cool and store rolls in a small space.

[Means for solving problems]

For this reason, the present invention is a multi-level warehouse equipped with a stacker crane, and a cooling water tank is provided in a part of the rack, and the rolling rolls can be transferred to and from the stacker crane above the cooling water tank. Its basic feature is that it has a roll support that can be lowered into the cooling water tank.

[Effect]

The rolling rolls are placed on the lifting table of the stacker crane, transported to a predetermined position where a cooling water tank is provided, and then transferred to a roll support stand located above the cooling water tank. The roll support base on which the rolling rolls have been transferred is lowered into the cooling water tank, and the rolls are immersed in the cooling water. After the soaking process of the rolling rolls is completed,
The roll support platform is raised, and the rolling roll is further transferred to the lifting table of the stacker crane, and the rolling roll is carried to a predetermined shelf position on the rack and transferred to the shelf.

〔Example〕

1 and 2 show an embodiment of the present invention, in which 1 indicates a plurality of shelves 3 in the vertical direction and in the longitudinal direction.
2 is a stacker crane.

This stacker crane 2 has a main body with a height corresponding to the height of the warehouse (racks), and has rails 4 installed along the longitudinal direction of the floor between the racks 1.
It is movably disposed on the top by rollers 5. A guide rail 6 is provided on the ceiling of the warehouse, facing the rail 4, and the upper end of the stacker crane 2 is connected to this guide rail 6 via rollers 7.
will be guided to.

The stacker crane 2 is equipped with an elevating table 8 that can be moved up and down in the height direction with a rolling roll placed thereon.

A cooling water tank 9 is disposed at the bottom of one of the racks 1 on both sides of the stacker crane. This cooling water tank 9 has an open upper part.
Although it is preferable to provide the cooling water tank 9 at the bottom of the rack as in this embodiment in order to effectively utilize the space at the bottom, the cooling water tank 9 is not necessarily limited to this and can be placed on any shelf of the rack. It can be provided in the section.

At the top of the cooling water tank 9, it is possible to transfer rolling rolls between the lifting table of the stacker crane.
A roll support stand 10 that can be lowered is provided in the cooling water tank.

In this embodiment, the roll support stand 10 is suspended at both ends from the upper part of the shelf by a lifting means 11 consisting of a chain block, and is capable of being raised and lowered. Note that as this elevating means, a winch, a lifter, or other suitable means can be used. For example, as shown in FIG. 3, a pantograph type link member 12 is expanded and contracted by a fluid pressure cylinder (not shown), It is possible to have a structure in which the roll support stand 10 is raised and lowered.

Any suitable method can be used as the mechanism for transferring the rolling rolls between the lifting table 8 and the roll support base 10, such as a method in which a conventionally known sliding fork type transfer device is provided on the lifting table, or a lifting mechanism is used. There are methods such as installing a trolley on the table. In this trolley system, a trolley is movably provided on a lifting table via a rail, and a rail is provided on a roll support base to communicate with the rail to move the trolley, and a plurality of lifting cylinders are connected to the carriage. The rolling roll is mounted on the support, and while the roll is held at a predetermined height with an elevating cylinder, the cart is moved to the roll support stand, and the elevating cylinder lifts the roll onto the support. The rolling rolls are placed on the roll support table by lowering the cart, and the transfer is then completed by returning the cart to the lifting table.

Furthermore, the type of stacker crane is not limited to that of this embodiment, and any suitable type can be used, such as a type in which the main body is suspended from the upper part of the warehouse.

Next, to explain the means for processing and storing rolling rolls according to the present invention, rolling rolls X brought from a rolling mill are placed in a warehouse and placed on a lifting table 8 of a stacker crane, as shown in FIG. The roll X is cooled by being transferred from the position indicated by the solid line to the roll support 10 at the bottom of the rack (position A in Figure 1), and then lowering the roll support 10 into the cooling water tank 9 (position B in Figure 1). do. After cooling for a predetermined time, the roll support stand 10 is raised, and then the roll X is transferred to the lifting table 8 and placed on a predetermined shelf 3 of the rack 1.
(For example, position C in FIG. 1).

[Effect of idea]

According to the present invention described above, it is possible to rationally cool and store rolling rolls without taking up flat space, and it is also possible to automate the process from taking in the rolls to cooling and storing them. It is.

[Brief explanation of the drawing]

FIGS. 1 and 2 show one embodiment of the present invention, with FIG. 1 being an overall explanatory view, and FIG. 2 being an explanatory view showing a roll support stand and a cooling water tank.
