Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for storing long and heavy objects such as steel materials such as steel plates and pipes and resin materials.

[0002]

2. Description of the Related Art As a conventional article storage device, Japanese Patent Laid-Open No.
The thing of 156627 gazette can be mentioned. This device includes a pallet on which articles to be stored are placed, a plurality of pallet storage shelves supporting the pallet in the vertical direction, frames arranged on the outer side in the longitudinal direction of the pallet storage shelves, and A pillar located in front,
An elevating body that is guided by a pillar and is vertically movable and is shorter than the depth of the pallet, a position that is guided by this elevating body and moves to the lower surface of the pallet, and when the pallet is vertically moved, the pallet storage shelf is not installed. The pallet supporting / conveying member independently guided to the left and right with a length shorter than twice the pallet depth moving to the position, driving means for horizontally moving the pallet supporting / conveying member, and the elevating body in the vertical direction. Drive means for moving, control means for vertically moving the lifting body when the pallet supporting and conveying member is not in contact with the pallet storage rack, and space for storing the pallet taken out at the bottom of the pallet storage rack. When,
When the articles to be stored are taken out from the pallet, the cargo handling and transporting device is located in the front space of the pallet storage rack sandwiched by the pillars, and the article is transferred from the pallet.

A pallet supporting / conveying member engaged with any pallet on the pallet storing rack is horizontally moved to the front of the pallet storing rack and taken out, and then the elevating body is lowered to the lowermost position of the pallet storing rack to support and convey the pallet. The members are moved to the side of the pallet storage shelves, and the pallets are stored and supported in the lowermost stage (first stage) of the pallet storage shelves. Then, the article on the pallet is taken out by a carrying-out means such as a manual forklift.

As a result, the pallet on which the desired article is loaded can be positioned on the first stage of the pallet storage shelf, and the unloading means for unloading the article can be brought close to the front of the pallet storage shelf. However, there is an advantage that the required depth dimension including the article storage device and the cargo handling / transporting device can be small.

[0005]

However, the pallet must be temporarily stored at the bottom of the pallet storage shelves. This is because the driving means for horizontally moving the pallet supporting / conveying member is provided inside the depth dimension of the lifting / lowering body. Therefore, when the pallet / conveying member supporting the pallet is lowered by the lifting / lowering body, the driving means is used. Is an obstacle (obstacle) and cannot be directly placed on the carrying-out means, that is, the cargo handling and transporting device. Therefore, extra movement is required to move the pallet taken out of the storage rack to a predetermined position.

Further, since the taken-out pallet is in the lowest storage rack, there is a problem that the articles in the pallet cannot be directly lifted from the pallet by a crane and conveyed.

The present invention has been made in order to improve the above problems, and provides an article storage apparatus which can reduce the depth dimension of the article storage apparatus and can easily take out articles from a pallet. The purpose is to do.

[0008]

In order to achieve the above object, the present invention is directed to a main body composed of left and right side frames and an upper frame which are open in the front-rear direction, and a rear side inside each of the side frames. And left and right sub-columns provided with a predetermined space from the side frame and provided with a plurality of mounting holes in the vertical direction, and the mounting holes in each of the sub-columns from the sub-columns toward the front side. A shelf board for mounting the pallet, which is provided with a plurality of steps in the vertical direction, and an article storage pallet provided with adjustable guide members on the upper and lower portions of the front and rear parts placed on each step of the shelf board; And is guided by the main pillar of the side frame to move up and down, and the length in the front-rear direction is longer than the depth dimension of the pallet but shorter than twice, and is guided by the lifting mechanism. It moves horizontally back and forth and A horizontal loading / unloading mechanism having a length in the front-rear direction that is shorter than twice the depth of the pallet, the horizontal loading / unloading mechanism being moved to a position not abutting against the shelf plate when descending; A structure comprising a horizontal loading / unloading mechanism drive means provided on the rear side of the elevating mechanism and a pallet mounting device positioned on the front part of the lower part of the main body is adopted.

[0009]

Function: The elevating mechanism is stopped at any position in the vertical direction. At this time, the horizontal loading / unloading mechanism does not project to the front part of the main body but is housed in the elevating mechanism and is in the retracted limit position.

On the other hand, an empty pallet containing articles is placed and stored on a shelf board.

When taking out a desired pallet article from this state, first, when the horizontal loading / unloading mechanism is horizontally moved from the elevating mechanism to the forward limit, the horizontal loading / unloading mechanism does not hit the pallet stored on the shelf board. After that, the elevating mechanism is moved up and down to a position below the pallet to be taken out and stopped. Further, when the horizontal loading / unloading mechanism is horizontally moved to the backward limit, the horizontal loading / unloading mechanism is located immediately below the pallet.

Next, when the elevating mechanism is slightly raised, the pallet is supported and levitated by the horizontal loading / unloading mechanism, and when the horizontal loading / unloading mechanism is moved forward again, the taken out pallet is stored in the pallet stored on the shelf board. It will be delivered to a position where it does not hit.

When the lifting mechanism is lowered from this state,
The pallet supported by the horizontal loading / unloading mechanism stands by in front of the lower part of the main body in advance, that is, it is transferred to the pallet mounting device located immediately below the lowering of the horizontal loading / unloading mechanism.

As described above, when the pallet is horizontally moved to the forward limit by the horizontal loading / unloading mechanism and then lowered by the lifting mechanism, the horizontal loading / unloading mechanism drive means is at the rear of the lifting mechanism, Since there is no obstacle in the space below, that is, between the left and right horizontal loading / unloading mechanisms, the pallet is directly transferred onto the pallet loading device.

Then, the articles in the pallet on the pallet loading device are directly lifted and transported by an overhead crane or a hoist.

Further, when changing the height of the pallet, the guide member is moved up and down from the pallet to set the required height. That is, the higher the guide material is, the deeper the pallet is and the more the pallet can be accommodated.

On the other hand, the mounting position (pitch) of the shelf plate with respect to the auxiliary column is also changed according to the height of the adjusted pallet. In this case, since a large number of mounting holes are provided in the sub pillar, the shelf plate can be easily and easily changed by changing the positions of the mounting holes.

In addition, the electric trolley for pallet loading moves from the storage space of the main body to the front part of the main body when the articles are taken out,
Since it is stored in the storage space of the main body when not in use, the space of the entire device is reduced. Moreover, by detecting the weight of the articles in the pallet with the weight detector, the weight of the articles can be accurately grasped, and the articles are not overloaded.

Since there is no obstacle, the pallet 7 can be directly transferred to the carriage 60.

Then, while the carriage 60 is kept stationary, the articles in the pallet 7 are directly hoisted by an overhead crane or hoist (not shown) to be conveyed.

As the pallet loading device, a movable loading device such as a movable loading platform or a forklift can be used in addition to the electric cart.

[0039]

Since the present invention is constructed as described above, it has the following effects. Since it is not necessary to store the pallet in the lowermost shelf plate as in the conventional case, it is possible to omit an extra transfer step and shorten the transfer time.

Further, since the pallet loading device can be brought close to the front position of the main body, the working space in the depth (in the front-back direction) required for taking out the article can be reduced.

Further, since the pallet is transferred to the pallet mounting device located in the front part of the main body, the articles in the pallet can be directly lifted by an overhead crane or the like, and the articles can be taken out very easily.

Further, since the height of the pallet is changed, the loading amount per pallet can be increased. As a result, the same type or lot of products can be stored in the same pallet.

Further, since the electric carriage is stored in the space of the main body when it is unnecessary, the space around the article storage device can be effectively used. Moreover, by providing the weight detector, it is possible to enhance the loading efficiency of the articles and prevent the articles from being overloaded, thereby improving the safety.

In particular, in the present invention, the mounting intervals of the shelf plates for supporting the pallet are changed by utilizing a large number of mounting holes provided in the sub-pillar, and the pallet is accommodated in the pallet by a guide member which is adjustably mounted. There is an advantage that the storage capacity of the articles can be changed.
