Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a method and equipment for storing cargo of long materials in a warehouse for storing cargo, particularly long materials such as pipes.

Conventionally, the warehouse for storing pipes was built in 1988-9220.
As shown in No. 6, there is a storage shelf with arms installed horizontally and vertically for storing pipes, a stacker crane that moves along this storage shelf, and a pipe is carried out to the waiting area of the stacker crane. It consists of a trolley for carrying people.

To explain the delivery process, multiple pipes are placed on the pipe tray of the truck, the truck is moved to the waiting area of the stacker crane, and then the multiple pipes are scooped out with the fork of the stacker crane, and then the pipes are moved to the stacker crane. The crane travels along the storage shelf, stops at a predetermined position, and unloads the product onto the shelf at a predetermined height.The crane is moved in the opposite direction to remove the product from the shelf.

As described above, since a storage shelf and a stacker crane are required, the construction cost thereof is extremely high.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a load storage method and equipment that can be constructed at low cost and have high storage efficiency.

[Summary of the invention]

In the present invention, a container is provided with a plurality of concave pedestals on the upper surface for supporting loads, and the containers are provided so that they can be stacked while being placed on the pedestals. , between the pedestals that support the load, the container and A trolley is provided, and the containers on the trolley are lifted by a crane and the loaded containers are stacked in a storage area.

[Embodiments of the invention]

The present invention will be explained below with reference to an embodiment shown in the drawings. Second
The figure is a diagram showing the planar arrangement of FIG. 1 with the roof, transfer a, and container crane removed.

In FIG. 2, 1 is an area for storing pipes, 2 is an area for storing pipes, and 3 is an area for taking out pipes.

The end pipes are carried in by a roller conveyor 10 or the like and are rolled in a right angle direction and arranged in parallel to the storage locations 11a and 11b. Running lines 12a, 12b, 1 in the direction perpendicular to this alignment direction
Trucks 13a, 13b with 2c-12n
, 13 c...13 n are arranged.

The trolley 13 travels along the rails.

As shown in FIG. 1, above the trolley 13 is a transfer machine 15a.
, 15b are installed. This transfer machine 15 is movable in the direction perpendicular to the running line ratio, and is able to move the trolley 1 from the storage location 11.
It can move within a range of up to 3 r+. 16 indicates a running rail. The transfer machine 15 is an overhead crane, and the lifting device 17
The hanging tool 17 can be moved up and down by a combination of a rope and a hoist, or a link mechanism, etc. The structure of the hanging tool 17 is as follows. For example, in a known stacker crane, a fork is provided on the side surface of the hoisting tool 17 so that it can move forward and backward in the horizontal direction, and when scooping up a pipe, the fork is protruded.Furthermore, when the fork is provided so as to be rotatable 90 degrees and scooping up a pipe, For this purpose, a fork placed parallel to the pipe may be rotated 90 degrees to protrude.Furthermore, the fork may be provided on both sides of the hanger so as to touch the pipes from both sides of the plurality of pipes. .

The storage area 2 has four containers containing pipes. The container housing the pipe is shown in Figure 1 (
They are placed on an extension of the running track and are stacked in stages as shown in FIGS. 1, 3, and 4.

As shown in FIGS. 3 and 4, the container opening is open at the top, especially at the top, so that the pipe 18 can be inserted from the top. This opening position is determined by the relationship with the transfer machine 15. Further, an engaging member η that engages with a lifting member of the container crane 21 is provided on the upper part of the container joint.

On the trolley 13 is an empty container called Beauty. For example, when a plurality of pipes are lined up at the storage location 11a, the transfer machine 1
5a moves to the location, lowers the hanging tool 17, scoops up the plurality of pipes, and raises it to the required trolley 13.
Move above d. There, the hanging tool 17 is lowered,
Transfer the pipe to an empty container.

Then, this trolley 13d runs and moves to the battle transfer location phantom a.

This transfer location 23a, storage area 2 and transfer location 23b
Above the space is a container crane 2 that can travel between the spaces.
1a, 21h, 21n, and 21n are arranged. Sae is a running rail. This container crane 21 is an overhead crane, and is equipped with a device as a lifting device that engages with a retaining member on the upper part of the container.

This configuration is, for example, a twist lock pin device, and is similar to a general container crane and is a known configuration. This container crane 21 is installed at a ratio of one °C to two running lines 12. For this reason, the hanging tool n is provided so as to be movable in a direction perpendicular to the running line 12 between the two runs i 12-12. Further, the hanging tool n is moved up and down by the rope 6 and the hoisting machine.

When the cart 13d carrying the container containing the pipe 18 moves to the transfer location 23a, the container crane 21c above the travel line 12d moves to the transfer location 23a. Then, the lifting tool n is moved above the trolley 13d and lowered to lift the container. Next, the container crane 21c is moved to the storage area 2 and unloaded to a predetermined position. In this case, if there is no container at a predetermined location, it will be placed on the ground, and if there is already a container, it will be stacked on top of the container.

Next, the unloading area 3 will be explained. Similar to the warehousing area 1, it is composed of carts 33a, 33b, 33cm.-=33n, transfer fi 35'a, 35b, etc.

When unloading, a predetermined container crane 21 lifts the container at a predetermined location and unloads it to the transfer location 23b,
The container is unloaded onto the cart 33 on which no container is placed.

The trolley 33 moves and transfers the cargo, and the truck 35 scoops up and unloads it to the delivery location 31a or 31b. This pipe is delivered by adding a roller conveyor or the like. The configuration of the transfer machine is the same as that of the transfer machine 15.

Next, the cart carrying the empty container moves to the transfer location 23b. The container crane 21 lifts up this empty container, moves it to a moving location 21a, and places it on an empty trolley 13. The trolley 13 moves to a position in either the transfer column 915a or 15b and waits in a movable state. Alternatively, empty containers are stacked at predetermined positions within the storage area 2 where empty containers are placed.

When storing containers in storage area 2, each running line 12
A column of container additions along the line is called a ``column,'' and a column of container additions perpendicular to it is called a ``row.''

A position consisting of columns and rows is called an "address".

Once the addresses that can be stacked are determined, empty travel lines 12.
Transfer fi 15, storage location 11, transfer location 1
1, the pipes carried in by the roller conveyor 10 are lined up and then stacked at predetermined addresses as described above. The same applies to shipping.

If there are multiple types of pipes to be stored, each having different lengths, diameters, materials, etc., the address is determined for each type.

As mentioned above, storage is performed by stacking containers. Therefore, storage shelves are not required, and although a large number of containers are required, the construction cost is reduced.

In addition, due to changes in demand, for example, if the diameter of the pipe to be stored becomes larger and the pipe cannot fit into the storage shelf or container, the conventional storage shelf method requires that the previous storage shelf be removed.
New storage shelves with large intervals must be installed, which requires an extremely large amount of time and expense. In the container system of the present invention, it is only necessary to change the size of the container, and the previous container can be taken out using the container crane 21, etc., and can be carried out at low cost, in a short time, and easily. .

On the other hand, when the diameter of the pipe becomes smaller, storage efficiency can be improved at low cost by reducing the height of the container according to the present invention.

As described above, the construction cost is low and the subsequent measures are extremely easy.

In the above embodiment, the storage location 11. Transfer machine 15° container crane 21. The reason why there are a plurality of transfer machines A and a plurality of unloading locations 31 is to shorten the processing time for one cycle of warehousing or unloading, and it can be done more or less as needed.

In the embodiment described above, the goods are entered from one end in the row direction and taken out from the other end, but the goods may be taken out only from one end. For example, 40a.

The position of 40b is designated as the transfer location, and the transfer machine 15 moves to this location.
makes it movable. Alternatively, the warehouse may be entered and exited from both ends respectively. This is determined based on the relationship between the content and location of the upstream process and downstream process.

Alternatively, a floor may be provided on the upper surface of the transfer a15.35, and empty containers may be stacked on the floor. in this case,
The container crane 21 can be moved up to the upper part of this floor to stack empty containers or to transport carts 13.3.
Supply and removal to 3. As shown in FIG. 2, since the transfer fi 15.35 is installed at a low location, the height of the building can be made almost the same as the storage area 2, and an increase in construction costs can be prevented.

Next, the structure of the container and truck 13.33 will be explained in detail with reference to FIGS. 5 to 10.

The trolley 13 has a plurality of pillars 41a1 on the upper surface as shown in
41b and pillars 413 and 4 slightly lowered from the upper end of the pillar.
A cradle 42 for receiving the pipe 18 is provided between the pipe 1 and the pipe 1b. The pillars 418, 41b+receiver form a concave holder with the pedestal 42. The structure between the carts is the same as that of the cart 13.

The container assembly is shown in FIG. 5 (consisting only of a frame. In other words, a pipe holder 51 is provided between two wooden beams 50a, 50b, and a plurality of pillars 52a, 5 are connected together.
2b is provided. The height of this pillar 52 is slightly larger than the diameter of the pipe 18. The distance between the inner surface of the beam 50a and the inner surface of the beam 50b is the distance between the outer surface of the column 41a of the truck 13 and the distance between the inner surface of the beam 50a and the inner surface of the beam 50b.
It is slightly larger than the distance to the outer surface of b.

Further, the position of the pedestal 51 is set so as to be located a little away from the pillar 41. Further, the distance between the pillars 52a and 52b is substantially the same as the distance between the carts 41a and 41b. The pillars 52a, 52b and the pedestal together with the pedestal 51 form a concave pedestal.

Therefore, as shown in FIGS. 7 to 10, when a container carrying pipe 18 is placed on truck 13, the container is lowered until the lower surface of the container rib comes into contact with the floor surface of truck 13. The pipe 18 remains on the upper surface of the pedestal 42 of the truck 13.

Therefore, a space 55 can be formed between the lower surface of the pipe 18 and the upper surface of the container support beam 50, into which the forks of the lifting devices 16, 36 of the transfer ie, 15, 35 can be accommodated.

Pillar 41 of truck 13. The support is between the platform 42 and the container joint.

The receiver is stand 51. The positions and sizes of the pillars 52 are determined so that the space 55 can be constructed.

For this reason, when warehousing, when the pipe 18 scooped up by the fork of the hanging tool 16 of the transfer machine 15 is unloaded onto the trolley 13 carrying the empty container, the pipe 18 as shown in FIGS. is placed on the cradle 42 of the cart 13. In this state, move the fork backwards and raise it.

Next, the container shown in FIGS. 9 and 10 is lifted by engaging the device 1i24 with the engaging member n of the pillar 52 using the lifting tool n of the container crane 21. The state will be as shown in FIGS. 7 and 8.

These are transported to the storage area and stacked in stages.

When leaving the warehouse, there is the above-mentioned play. container crane 21
Figure 9 shows when the container is unloaded onto the trolley.

The state shown in Figure 1O is reached. A space 55 is created, so insert the fork of the transfer S35 into this space and lift it up.

As mentioned above, the air gun 5 for the fork of the transfer machine 15.35
5 is a trolley 13. It is configured by a combination of a container and a container. It is also conceivable to not provide the pedestal 42 on the cart 13.33, but to provide a pedestal 51 for the container above the beams to provide a space for the fork. However, according to the method shown in the figure, since the space for the oak tree is not needed in the container addition, the height of the container addition is slightly larger than the height of the pipe 18 plus the height of the beam 5°. good. Therefore, even if the pipe is small, the height of the container can be reduced according to the pipe diameter.
The number of stacks in the storage area 2 can be increased, and storage efficiency can be improved.

Pillar 41. It is desirable that the inner side of the upper end of the pillar 52 is provided so as to expand upward to facilitate the transfer of the pipes 18 between them.

FIG. 11 shows another embodiment of the container. The sum of the height Hl of the upper column 55 and the height H2 between the lower columns is made slightly larger than the diameter of the pipe. 57 is a protrusion for facilitating the transfer.

Developing the concept of the embodiment shown in FIG. 11, this will be explained using an embodiment shown in FIGS. 12 and 13. In FIG. 12, the container 60 is provided with a plurality of columns 62a, 62b on the upper surface of two beams 61a, 61b, and these columns 62a,
A holder 63 for a pipe holder is arranged between 62b. The position of the stand 63 is such that the fork of the transfer a15, 35 can be inserted between the top surface of the stand 63 and the top surface of the beam 61, and it is also slightly lowered from the top end of the pillar 62. be. When the containers ω are stacked, they are installed so that pipes can be stored between the containers as in the embodiment shown in FIG.

As shown in FIG. 13, the truck 65 does not have a pipe holder. A stopper is provided to prevent the container 60 from falling. The container 60 is placed on the cart 65, and the pipe 18 is placed on the pedestal 63 of the container ω. A space 55 into which the fork of the transfer machine 15 enters is formed between the pipe 18, the beam 61, and the column 62. This embodiment is advantageous for large pipe diameters, ie large load heights.

In this case, since the container requires space for the fork to fit, if the load is tall, the space for the fork to fit is relatively large compared to the height of the container, reducing storage efficiency.

In the above embodiment, the height of the load is a pipe, but other long objects may be used. Also, the length of the load may vary as shown in the figure. Alternatively, it may be possible to place loads into one container in multiple stages.

〔Effect of the invention〕

As described above, in the present invention, a container is provided with a plurality of concave pedestals on the upper surface for supporting loads, the containers are provided so that the containers can be stacked while being placed on the pedestals, and the containers and the loads are placed on a trolley. When the load is loaded, there should be a space below the load for the fork of the transfer machine to fit between the pedestals that support the load, and a space that allows the fork to move above the cradle. A container and a truck are provided in the container, and the containers on the truck are lifted by a crane and the containers containing cargo are stacked in a storage area, so that storage equipment can be provided at low cost and storage efficiency can be improved.
