Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a three-dimensional automatic warehouse for steel materials, and more particularly to an automatic three-dimensional warehouse for the purpose of storing steel materials such as bar steel and elongated steel plates.

[0002]

2. Description of the Related Art Conventionally, in the case of storing steel materials such as bar steel and elongated steel plates, the steel materials are piled up on the sleepers directly laid on the floor of a warehouse or factory, and the sleepers are further stacked on these steel materials. Lay it and store it by stacking it, and move the steel material with a well-known forklift or crane, or store the steel material in a framework that consists of columns, beams and plates and can be moved directly with a forklift or crane. However, it is the actual situation that these frameworks are stacked or placed, or either method is adopted.

[0003]

However, in the former method, it is necessary to stack the same kind of steel materials in order to stably stack the steel materials, and there is a limit to the height at which the steel materials can be stacked. The storage space tends to expand laterally, which has the drawback that a large area is required to store a large amount of steel material. Further, in the latter method, since the steel material can be moved only in units of frameworks, it is easy to cause waste such as transporting more than necessary steel material to the work space or the shipping space, and for the convenience of storage and management of stored steel materials. However, one type of steel material is often stored in one framework, and there is a problem that a storage space is likely to be wasted, such as a framework that is not filled with steel material.

The present invention has been made to solve the above-mentioned problems, and an object of the present invention is to provide a three-dimensional automatic warehouse for steel products which can be separately stored according to the rigidity of the steel products.

Another object of the present invention is to store various lengths of steel material without waste of storage space, and to allow various lengths of steel material to be freely taken in and out of various lengths of storage space. It is to provide a three-dimensional automated warehouse for steel materials.

[0006]

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned object, and its gist is to provide a track, a carrier traveling on the track, and parallel to both sides or one side of the track. The storage area is composed of a plurality of storage areas that are vertically adjacent to each other and that are horizontally adjacent to each other, and the storage areas are arranged in parallel with each other along a track. Main pillars arranged at intervals, beam members connecting between the main pillar members, and sub-columns provided between the main pillar members at several hierarchical levels and supported by the beam members. Between the main pillar materials not including the sub pillar material, and a shelf material provided on each of the main pillar material and the sub pillar material at the same height at predetermined intervals. A high-rigidity steel material is spanned and stored in the shelf material of the floor, and the floor material including the main pillar material and the sub pillar material is stored. The shelf member, appropriately select one of the low steel or rigid steel rigidity depending on the pillar spacing, in steel for stereoscopic automatic warehouse comprising and stored bridged.

In the three-dimensional automated warehouse for steel products of the present invention, the steel products having high rigidity mean standard shaped steels such as angle steel, angle steel, I-shaped steel, H-shaped steel and grooved steel (channel). Yes, and steel materials with low rigidity are flat steel (flat bar), steel plate (plate), bar steel such as round steel or square steel,
And lightweight section steel, and examples of the lightweight section steel include lip groove section steel, light groove section steel, lip Z section steel, lip chevron section steel, light Z section steel and hat section steel. Furthermore, the orbit is
Two I-shaped steels, H-shaped steels, groove-shaped steels, and I-shaped bar steels can be formed in parallel, or one can be laid on the floor surface to form the storage compartment. The pillar material, the main beam material, the auxiliary pillar material, and the shelf material can be formed of the standard shaped steel or the lightweight shaped steel described above.

In the three-dimensional automatic warehouse for steel products of the present invention, when hierarchizing, the number of hierarchies can be appropriately determined, and any number of sub-columns may be provided in any one of the hierarchies. In the case where the upper and lower layers are hierarchized, by providing the sub-column member preferably in the lower layer, the lower layer can be densely supported by the main column member and the sub-column member to support the upper layer. Therefore, even when two or more hierarchies are used, the lower the level is, the closer the main pillars and sub-columns are arranged, the higher the stability of the storage compartment as a structure. Can be made. Moreover, since the shelf materials are provided at the same height at predetermined intervals for each of the main pillar material and the sub pillar material,
Unlike conventional horizontally continuous shelves, a space is created between the shelves, so that the fork of the carrier can be inserted into this space and passed vertically, It is possible to lift the steel material that is bridged between the materials and stored, or to lower the steel material to bridge the shelf materials.

Further, in the three-dimensional automatic warehouse for steel products according to the present invention, the shelf material of the layer including the main pillar material and not the sub pillar material is
As described above, the shelf members are provided on the main pillar member and the sub pillar members at the same height at predetermined intervals, but there is no sub pillar member and only the main pillar member exists in this layer. Therefore, the interval between the pillar members is widened, and thus the interval between the shelf members having the same height is widened. For this reason, when a steel material having low rigidity is bridged between the shelf materials, the steel material is likely to be bent and distorted. Therefore, a steel material having high rigidity and difficult to bend is stored in the shelf material of this hierarchy. Further, in the layer including the main pillar material and the sub pillar material, the density of the pillar material is higher than that in the hierarchy that does not include the sub pillar material, so that the interval between the shelf materials is narrow and the rigidity between the shelf materials is low. Even if the steel materials are bridged, the steel materials are supported by many shelves, so that the steel materials do not easily bend or distort. Therefore, in the shelf material of this hierarchy, according to the density of the main pillar material and the sub pillar material, that is, the shelf material interval, appropriately store the steel material having low rigidity,
In addition, steel materials with high rigidity can be stored.

Another feature of the present invention is that the carrier comprises two columns that travel on the track, a fork support member bridged between the two columns, and a fork support member that moves up and down. And a means for supporting the fork, a plurality of forks supported by the fork supporting member and provided in a direction intersecting with the track, and a slide means for individually sliding these forks in both directions of the fork axis. According to the size, a predetermined number of forks are slid and moved up and down so that steel materials of various lengths can be put into and taken out of storage spaces of various lengths.

In the three-dimensional automatic warehouse for steel products of the present invention, the wheels running on the track are provided at the lower ends of the two columns arranged on the track at substantially equal intervals with the partition length, and both or one of the columns is provided. If a motor for driving the pillar is provided and the wheels are driven by the pillar driving motor, the carrier can be run on the track. Further, the lifting means for moving the fork support material up and down is provided with pulleys at the upper and lower ends of the two columns,
An endless belt, for example, a chain, a rope, and a reinforcing fiber belt is stretched between the pulleys and the propelling drive motor is a motor with an inverter, or a motor for driving the endless belt is separately provided. Can be configured. Further, a plurality of forks supported by a fork support member and provided in a direction substantially orthogonal to the orbit mean that when the two columns are arranged at substantially equal intervals with the partition length, each fork slides. When extended, it is inserted so that it can be inserted into the space between the shelves and moved up and down. Furthermore, the slide means for individually sliding the forks in both directions of the fork shaft may be constituted by a pulley, a roller, a motor, or the like, or a pulley, a roller, a hydraulic cylinder, or the like.

As described above, in the three-dimensional automatic warehouse for steel products according to the present invention, the carrier is provided with two pillars arranged on the track at substantially equal intervals with the section length, and forks along the two pillars. It is provided with a fork having a vertically moving lifting means and a sliding means that slides in both directions of the fork shaft.
Furthermore, since each fork is inserted in the space between the shelves and arranged so that it can move up and down, steel materials of different lengths can be placed and stored on the shelves of the same height. Even in such a case, depending on the length of the steel material that needs to be taken out, only an arbitrary number of forks can be slid up and down, and only the predetermined steel material can be lifted and taken out. In addition, even when the steel materials are already placed and stored between the shelf materials when entering, and there is an empty space between the shelf materials next to the same partition, the empty space and the length of the steel material to be stored A predetermined number of forks can be slid up and down according to the number of forks to place and store a predetermined steel material between the shelves in the space. Therefore, the three-dimensional automatic warehouse for steel products of the present invention makes it possible to take in and out steel products such as strip steels and elongated steel plates of various lengths with the section length as the maximum length in the storage spaces of various lengths.

[0013]

In the three-dimensional automatic warehouse for steel products according to the present invention, each of the main pillar material and the sub pillar material is provided with a shelf material at the same height at a predetermined interval, and the carrier is provided between the shelf materials. Has a fork that is arranged so as to face the space, and each fork slides independently, so steel materials such as strip steel and elongated steel plates with different lengths can be loaded and unloaded between shelf materials of the same section and the same height. be able to.

Next, a description will be given of the procedure for storing steel products such as strip steel and elongated steel plates in the warehouse of the present invention.

Prior to the receipt, the receipt status is confirmed by a personal computer in the office (hereinafter simply referred to as a personal computer), and the type, length, quantity, etc. of the steel material to be entered are entered into the personal computer, and then the receipt is carried out by the personal computer. Give instructions.

At this time, the crane 2 is mounted on the loading / unloading table 11a.
The steel material is hung and placed on the transportation vehicle 30 by the transportation vehicle 9, and the carrier 2 moves toward the position of the loading / unloading table 11a at the origin, for example, section A and E in FIG. 3 (a).
Move from the position between the parcels. The carrier 2 stopped before the loading / unloading table 11a slides and extends the fork 22 at a height lower than that of the steel material placed on the loading / unloading table 11a, and inserts it under the steel material before raising the fork 22. Then, the steel material is pushed up and the fork 22 is slid and contracted again, and the steel material is drawn onto the carrier 2 and loaded.

After the steel material is loaded, the carrier 2 moves to a storage compartment, for example, compartment A, which is to be stored, and stops before the compartment. The carrier 2 stopped before the section A raises the fork support member 25 to the upper side of the shelf where the steel material is to be stored, then slides and extends the fork 22, and then lowers the fork support member 25 to the lower side of the shelf. The steel material is placed on the shelf by sliding it, and then the fork 22 is slid and contracted. In this way, when the storage of the steel material is completed, the carrier 2 again moves to the origin.

In the above warehousing operation, when the warehousing steel is a steel having a high rigidity, the deformation due to bending does not easily occur even if the support point spacing, that is, the shelf material spacing is wide, and therefore the warehousing is stored in the upper floor 5. To do. On the other hand, when the steel material to be stored is a steel material having low rigidity, if the shelf material interval is wide, deformation due to bending is likely to occur, so the steel material is stored in the lower layer 6 having a narrow support point interval, that is, a narrow shelf material interval. However, lower level 6
When there is an empty shelf, a steel material having high rigidity may be stored in the lower layer 6.

Further, in the above-mentioned warehousing operation, when the length of the steel material to be warehoused corresponds to the length of the substantial storage compartment as shown at 30a in FIG. 3B, all 12 forks 22 are Alternatively, only the forks at both ends or the number of forks required to support the steel material may be appropriately slid and extended.

Further, as in the case of storing the steel material 30b in FIG. 3 (b), even if the steel material 30c has already been stored in the fifth stage, between the shelf materials of the main pillar materials 7a and 7b, There is a space where the fork 22 of the carrier 2 can be inserted and moved up and down,
Moreover, since the fork 22 of the carrier 2 can slide and extend only the four forks provided at the position corresponding to the shelf between the main pillar members 7a and 7b, the steel member 30
The steel material 30b can be stored between the shelf materials of the fifth-stage main pillar materials 7a and 7b regardless of whether or not the steel material is present at the position of c.

Next, a procedure for unloading steel materials in the warehouse of the present invention will be described.

Prior to delivery, the receipt status is confirmed by the personal computer in the office, the type, length, quantity, etc. of the steel material to be delivered are entered into the personal computer, and then the personal computer issues a delivery instruction.

The carrier 2 moves from the origin and stops in the storage compartment in which the steel material to be delivered is stored, for example, in front of the A compartment. The carrier 2 stopped before the section A raises the fork support member 25 to insert the fork 22 under the steel material to be delivered, for example, the steel material 30e, and moves the second stage shelf material and the third stage material. Stop between shelves. After that, the fork 22 provided at the position corresponding to the shelf between the sub pillars 9a and 9b is slid and extended, and then the fork support member 25 is raised to push up the steel material 30e with the fork 22. Then, slide the fork 22 back and forth again,
The steel material 30e is drawn into the carrier 2.

Then, the carrier 2 is moved to the loading / unloading tables 11a and 1a.
After moving to the front of 1b and raising the fork support material 25 to a position higher than the loading / unloading table, the fork 22 is slid and extended, and the fork support material 25 is lowered to a position lower than the loading / unloading table, so that the steel material 30e Is placed on the loading / unloading stand. After that, the fork 22 is slid and expanded to move the carrier 2 to the origin position.
