Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a container for storing objects, and particularly to a container that covers the entire object.

Automated warehouses are known as equipment for storing things. In this automated warehouse, substrates 1 loaded with objects can be taken out from racks in a three-dimensional storage arrangement using a stacker crane, or stored in the racks. As shown in FIG. 1, the rack is constructed by attaching support members 3 to a column 2 in multiple stages. This support material 3
The area between the top and bottom is one storage location. As shown in row A in FIG.
placed on top and stored.

A conventional container 4 has an open top surface, as shown in row A in FIG. 1, and stores a product 5 therein.
On the other hand, as shown in FIG. 1, the automatic warehouse is equipped with a fire extinguishing sprinkler 6 above, and fire extinguishing water is sprayed from the sprinkler 6 when extinguishing a fire.
For this reason, the product 5 in the container 4 had the disadvantage that the product value was reduced due to flooding. Furthermore, when handling or transporting the substrate 1 with a stacker crane, the product 5 may be damaged due to an accident in which the container 4 on the substrate 1 falls from the substrate 1, or the container 4 together with the substrate 1 falls. It is easy to cause defects such as scattering and damage.

In particular, when the product 5 is a dangerous substance such as nuclear fuel, each of the above-mentioned drawbacks may lead to a serious accident.

An object of the present invention is to reliably prevent deterioration in value, scattering, and damage of stored items in containers for storing items.

The main point of the present invention is that, as a basic structure, the entire stored item is covered with two blocks, one of which has a stopper extending horizontally, and a space large enough for the stopper to enter. It has a support provided on the other block, a groove provided in either the support or the other block with a size large enough to fit the stopper, and a leaf spring provided in a portion facing the groove with its acting direction facing the groove direction. death,
When the stored item is covered with two blocks and one of the blocks is rotated to insert the stopper between the support and the other block, the stopper is pushed by the leaf spring and fits into the groove, and both blocks become one piece. This minimizes external influences on stored items and prevents stored items from scattering.When removing stored items, remove the stopper from the groove and then reverse either block to separate both blocks. It is in the point of doing.

An embodiment of the present invention will be described below with reference to FIGS. 1 to 11.

In this embodiment, as shown in column B of FIG.
This is an example of a storage container for storing products stored on the support member 3 of the pillar 2.

The substrate 1 is a rectangular plate as shown in FIG.
Supports 7 are fixed to each of the four corners of this substrate 1.

Further, on the substrate 1, as shown in FIGS. 2 and 4, a circular inner support 8 having a size that surrounds the lower periphery of the container 4 is erected and fixed.

The cover 9 is as shown in FIGS. 2, 4, and 5.
It has a diameter larger than that of the container 4 and the inner supports 8, and has a shape in which the upper end surface of a cylindrical member having a diameter large enough to fit between the supports 7 is closed. A total of four stoppers 10 are fixed to the cover 9 at equal angles so as to project horizontally outward. There are hooks 11 at three locations on the upper side of the cover 9 at equal angles as shown in FIG.
It is attached as shown in Figures 6, 7, and 8.

As shown in FIGS. 9 and 10, the structure of the support 7 has a space between it and the substrate 1 having a size l into which the stopper 10 can enter, and a portion thereof is an upper groove 12 recessed upward.

A portion of the substrate 1 facing downward from the upper groove 12 is a lower groove 13 that is recessed downward. One end of a leaf spring 14 is fixed to the bottom of this lower groove 13 with a bolt 15.

A hanging tool 16 in FIG. 6 is a part for hanging the hook 11. The hanging tool 16 has three hooks 1.
It is fixed to three positions of the hanging beam 17 at equal angles so as to correspond to the position No. 1. The hanging beam 17 is fixed to a rotating shaft 18 connected to the prime mover and can rotate as shown by arrows S and V in FIG. Further, the rotating shaft 18 and the prime mover are supported so as to be vertically movable as indicated by arrows T and W in FIG. The structure of the hanging tool 16 is as follows:
As shown in FIGS. 7 and 8, it has an entrance L through which the hook 11 can pass, stopper surfaces 19 and 20 facing both sides of the hook 11, and a receiving surface 21 that supports the hook 11. Of the stopper surfaces 19 and 20, the stopper surface 19 on the entrance/exit L side is lowered to allow the hook 11 to enter and exit.

The workbench 22 shown in FIG. 11 includes a loading platform 23 for receiving the substrate 1, and four fixing fittings 24 fixed on the loading platform 23 and positioned to face the corner end surfaces of the substrate 1. This fixture 24 is the plate 1
It is also sufficient to have a protrusion of a height opposite to the end face of the corner.

In this embodiment having the above configuration, when the container 4 containing the product is to be stored in a rack, the container 4 is placed inside the inner support 8 and supported by the substrate 1. Next, as shown in Figures 2 and 3, each support 7
A cover 9 is placed over the container 4 so that the stopper 10 is in contact with the upper surface of the substrate 1 located between the two. Once the cover 9 is placed on the substrate 1 in this way, the cover 9 is rotated in the direction of the X arrow in FIG.

When the cover 9 is rotated in the direction of the arrow X, the stopper 10 moves between the support 7 and the substrate 1 in the direction of the arrow Y in FIG. As this approach progresses,
The stopper 10 rides on the leaf spring 14. Therefore, the stopper 10 is pushed up by the leaf spring 14 and fits into the upper groove 12. Therefore, the stopper 10 is pressed against the support 7 by the leaf spring 14. Therefore, only the weight of the cover 9 and a slight force applied downward to the cover 9 can cause the stopper 1 to
0 will not come out of the upper groove 12 and move downward. Due to the engagement between the stopper 10 and the support 7, the vertical direction of the stopper 10 is restrained by the leaf spring 14 and the upper surface of the upper groove 12, and the stopper 10 is restrained in the vertical direction by the leaf spring 14 and the upper surface of the upper groove 12.
The left and right rotation direction of the upper groove 12 is restricted by the left and right end surfaces of the upper groove 12. Therefore, it is possible to prevent an accident in which the cover 9 comes off from the substrate 1 and the product in the container 4 is scattered onto the floor or damaged. In particular, movement around the lower part of the container 4 is restrained by the inner support 8, which has a smaller diameter than the cover 9, so it is safe because the center of gravity of the load does not change during transportation or storage, and the container 4 and the cover 9
It is also possible to prevent contact with the product and any adverse effects on the product caused by this contact.

After the cover 9 and the substrate 1 are connected together as described above, the container 4 is stored together with the cover 9 and the substrate 1 into a desired storage position in the rack using a stacker crane. When storing, the bottom surface of the end of the board 1 should be
As shown in row B in FIG. 1, it is stored by being received by a support member 3 fixed to a column 2. After being stored, the cover 9 prevents the product from being submerged even if it receives water from the sprinkler 6.

When taking out a container containing a product, first take out the cover 9 and the board 1 from the rack side using a stacker crane. Next, by pressing down the cover 9, the stopper 10 is brought into contact with the surface of the substrate 1. After that, rotate the cover 9 in the counter-X arrow direction and remove the stopper 1 from between the support 7 and the board 1.
Remove 0. After the stopper 10 is removed, the cover 9 is lifted upward and separated from the substrate 1. After the separation operation, the container 4 on the substrate 1 is taken out.

The work of connecting and separating the cover 9 from the substrate 1 is carried out using the workbench 22 shown in FIG. 11, the workbench shown in FIG.
It is preferable to use a hanging device 16 shown in FIGS. 7 and 8. This usage method is advantageous when a heavy cover 9 that cannot be operated manually or a leaf spring 14 that generates a large force is used.

The case of working using the hanging tool 16 and the workbench 22 will be described below.

First, place the fixing bracket 24 onto the loading platform 23 of the workbench 22.
Place the board 1 within the area surrounded by. Next cover 9
The hook 11 is hooked onto the receiving surface 21 of the hanging tool 16 as shown in FIGS. 7 and 8. This hooking operation involves positioning the hanging tool 16 by moving in the direction of the arrow T to the position indicated by the two-dot chain line shown in FIG. This is done by storing it in the holder and pulling it up in the direction of the arrow W. The cover 9, which has been lifted up by the hanger 16 in this manner, is lowered by movement in the direction of the arrow T until the stopper 10 comes into contact with the substrate 1. Thereafter, the side surface of the hook 11 is pushed by the stopper surface 19 in the direction of the V arrow. As a result, the cover 9 rotates, the stopper 10 enters between the support 7 and the substrate 1, and is pressed against the upper groove 12 by the leaf spring 14, so that the cover 9 and the substrate 1 side are integrally connected.
After the connection, the hook 11 is removed from the hanging tool 16 from the entrance L by performing the reverse procedure of hooking the hook 11. When the cover 9 is rotated on the board 1, the board 1 tries to rotate in the same direction as the cover 9, but
Rotation of the substrate 1 is prevented by the end surface of the substrate 1 hitting the fixture 24, and the stopper 10 reliably enters between the support 7 and the substrate 1 and is pressed. Also when separating the cover 9 from the board 1, the board 1 is placed on the loading platform 2.
3 and place it within the area surrounded by the fixing fittings 24. To separate the cover 9, first store the hanging tool 16 in the hook 11, then push the top surface of the cover 9 with the hanging beam 17 by moving in the direction of the T arrow in FIG. . Thereafter, the side surface of the hook 11 is pushed by the stopper surface 20 by movement in the direction of the S arrow. If you press like this,
Cover 9 rotates and stopper 10 supports 7
and the board 1. Once the stopper comes out, move in the direction of arrow W to release the receiving surface 21 of the hanging tool 16.
Lift up the bottom of hook 11. For this reason,
The cover 9 is separated upwardly from the substrate 1. In this case as well, when the cover 9 rotates, the substrate 1
Although the substrates 1 also try to rotate in the same direction, the rotation of the substrates 1 is prevented by hitting the fixing fittings 24 on the loading platform 23, and only the cover 9 is rotated reliably, so that the separation operation is reliably accomplished.

As described above, the present invention has a basic configuration in which the entire stored item is covered with two blocks.
A support provided on one block with a space large enough to allow a stopper to enter extending horizontally on one block, and a groove provided on either the support or the other block large enough to fit the stopper. and a plate spring provided in a portion facing the groove with its acting direction facing the groove direction, and by simply rotating either block, the stopper is pressed into the groove by the plate spring and securely fits. Since the stopper is restrained within this groove and the two blocks are reliably integrated, it is possible to reliably prevent the stored items covered by the two blocks from deteriorating in value, scattering, or being damaged.
