Description

[Detailed Description of the Invention] The present invention is a method for storing long items in a sorted state, especially among steel materials produced in a steel factory and steel materials sent as a relay to a distribution center, and for taking them in and out. This relates to storage equipment for the largest items.

In the past, many long goods storage facilities had no ground equipment and were handled by overhead cranes, but in recent years rack-type long goods warehouses similar to automatic warehouses have been constructed from the viewpoint of storage efficiency and labor saving. It is being done.

Typical examples of these automated warehouses are shown in Figures 1 and 2.
As shown in the figure. In such a rack-type warehouse, the largest items 1 are stored in rows independently on cantilever-shaped shelves 2, while a stacker crane 3 runs along the side of the shelves 2 to pick up long items. It is configured to scoop up object 1. According to this warehouse, cargo handling is easy, but a passage for the stacker cranes 3 is required for each row, resulting in low storage efficiency.

Also, since the shelf 2 is a cantilever beam, there are concerns about its strength. 'b
- It is necessary to move the stacker crane itself in both the longitudinal and lateral directions of the long object 1.

Therefore, the structure, drive device, and warehouse equipment of the crane itself become large-scale. [c' Because the crane travels a long distance and the control becomes complicated, the cycle time tends to become longer.

There are drawbacks to this, and it is regrettable that the expected effects may not be achieved with respect to the ratio of capital investment.

For this reason, rack-type warehouses are currently limited to cases with extremely high operating rates or small-scale facilities, which has the disadvantage of limiting the scope of application. The present invention has been made based on the above-mentioned problems, and an object of the present invention is to provide long object storage equipment that has a high storage density for long objects, is advantageous in terms of strength, and is easy to take in and out. The present invention is characterized by comprising a storage shelf for storing long objects and a long object handling device therefor, the storage shelf comprising a pillar and a shelf member horizontally attached to the pillar, The structure is such that long items can be inserted and stored in the depth direction from each frontage.

In addition, the long object handling device has a frame that moves along the frontage of the storage shelf so that it can be positioned with respect to each of the storage shelves, a support part that is provided on the frame so that it can move up and down, and a support that is placed on the storage shelf. A grip part is provided on the support part in order to grasp and pull out the tip of the long object held on the cargo handling device and push the long object onto the shelf, and this grip part is attached to the support part. On the other hand, it is provided with a loading/unloading section that moves the frame in the same direction as the frame movement direction. An embodiment of the present invention will be described below with reference to the drawings.

3 and 4 show the overall configuration of the equipment of the present invention, and in the figures, the storage shelf 4 is composed of a branch office 5 and a shelf member 6.

On each stage of the storage shelf 4, the largest objects 1 of various sizes are sorted and stored in the horizontal direction. This elongated object 1 is placed in each shelf member 6 in a state in which it protrudes by a certain length from the frontage surface 4a of the storage shelf 4 in the depth direction of the storage shelf 4, as shown in FIG.
If it is placed on the holder, it will be easier to take it in and take it out using the grip section described later. The loading and unloading of this long object 1 is performed by the longest object loading device 7. This device 7 moves along the opening 4a of the storage shelf 4, moves to a position where the long object 1 is loaded into and taken out from the specified opening of the storage shelf 4, and is stopped at a position where the long object 1 is loaded and unloaded from the transport vehicle 8. Ru. This largest cargo handling device 7
In this example, it is shown suspended on the rail 9. The long object handling device 7 is a frame that has a length capable of holding the long object 1 in a plane parallel to the depth direction and the vertical direction of the storage shelf 4 and moves along the frontage of the storage shelf 5. It has 10. This frame 1 is provided with a support part 12 that can be moved up and down horizontally along the frame 10 by an elevating device 11.
This support portion 12 can support the elongated object 1 so as to be movable along its longitudinal direction. A grip part 13 that moves parallel to the depth direction of the storage shelf 4 is provided on the support part 12. The grip portion 13 grips the end of the long object 1 on the storage shelf 4 to pull out and push the long object 1. The gripping part 13 is provided with a sliding part 14 for moving the gripping part 13 in the same direction as the frame movement direction with respect to the support part. Each of these devices is operated on-machine or automatically from the operator's cab 15. The detailed structure of the storage shelf 4 described above is shown in FIGS. 5 to 7.

First, in FIGS. 5 and 6, the shelf member 6 consists of a roller shaft 6a and a roller 6b attached to the roller shaft 6a.
This roller 6b reduces the frictional force between the elongated object 1 and the shelf when the elongated object 1 is taken in and taken out. The roller shaft 6a of this shelf member 6 is inserted into the elevating groove 16 of the support column 5 so as to be able to move up and down. This roller shaft 6a is normally pushed upward by a support spring 17. As shown in FIG. 7, the shelf member 6 having the above-mentioned configuration has a degree of inclination that is slightly downward in the depth direction regardless of the presence or absence of the elongated object 1. Therefore, at the time of storage, the long object 1 is sent into the storage machine 4 in the attitude shown by the symbol ■ in the figure. Therefore, roller 6
The sliding movement by b and the elasticity of the support spring 17 have the effect of reducing the pushing force of the elongated object 1. Furthermore, when leaving the store, the gripping section 13 presses down the tip of the long object 1 from above to grasp it and pull it out, so that the longest object 1 is inclined toward the exit. As a result, there is an effect that the force for pulling out the elongated object 1 can be reduced. Although a means for raising and lowering the shelf member 6 using the support spring 17 is shown here, it is also possible to move the shelf member 6 using the elongated object handling device 7 and forcibly change the height of the shelf from the outside. The detailed structure of the long article cargo handling device 7 will be explained with reference to FIG.

A frame 101 of the long object handling device 7 is loaded with grain so that the support portion 12 can be moved up and down.

This support part 12 is positioned at an arbitrary height by a lifting device 11 (not shown). This support part 12 has a rail 1
8 has been installed. A grip section 13 and a loading/unloading section 14 are movably provided on this rail 18. This grip part 1
3 and the unloading section 14 are freely moved on the rail 18 by a drive device 19 and a cable 20. As shown in the figure, the gripping section 13 moves left and right while gripping the end of the elongated object 1. When taking out the long object 1, grasp the end of the longest object 1 on the shelf member 6 at the position ■ and pull it out to the position @. Further, when inserting the long object 1, the user grasps the long object 1 at the @ position and moves it to the ■ position. The detailed structure of the grip section 13 and the loading/unloading section 14 will be explained with reference to FIG. 9.

The long object 1 is transported on a plurality of rollers 20 extending horizontally from the support section 12.

The elongated object 1 on the roller 21 is gripped at its upper part by a pair of fingers 22 forming the gripping section 13 . This gripping and releasing operation of the fingers 22 is performed by driving a rack 23 installed above the fingers 22 by a single gear 24. In the figure, when rotated to the right, both fingers 22 move inward on the support shaft 25 and grip the long object 1, and when rotated to the left, they move outward and grip the long object 1.
to release. A loading/unloading section 14 for moving this gripping section 13 in the moving direction of the frame 10 is connected to a rack 26 which is parallel to the moving direction of the frame 10 and is provided horizontally.
By rotating the gear 27 to the left, the long object 1 gripped by the gripping part 13 can be taken off from above the roller 21, and by rotating the gear 27 to the right. With this, the longest object 1 grabbed outside can be placed on the roller 21. When performing such an operation, it is necessary to move the support portion 12 a small distance in the vertical direction or in the horizontal direction. Next, the storage/loading/unloading operation of the warehouse of the present invention described above will be explained with reference to FIG. 10.

First, the case where the long object 1 is placed in the storage shelf 4 will be described.

The long object 1 placed on the loading platform of the transport vehicle 8 is gripped by the fingers 22 of the gripping section 13. At this time, the finger 22 is in a state of being pushed out to the tip by the loading/unloading device 14. Therefore, by pulling this in, the long object 1 can be placed on the roller 21. During this operation, by raising and lowering the support section 12 or moving the frame 10 and the loading/unloading section 14, the longest object 1 is moved over the entire longitudinal direction by a plurality of rollers 21.
It can be placed smoothly on top. After this, the support part 12 is used to align the long object 1 with the specified opening of the storage shelf 4.
is raised and lowered, and the frame 10 is also moved. As a result, the end of the long object 1 is aligned with the shelf member 6, so
The elongated object 1 can be pushed into the storage shelf 4 by making the gripping part 13 and the loading/unloading part 14 run along the rail 18. At this time, the long object 1 is smoothly transferred on the rollers 21 and the shelf member 6. Next, the case where the long object 1 is taken out from the storage shelf 4 will be described.

The support part 1 is attached to the end of the long object 1 placed on the storage shelf 4.
2 and moving the frame 10.
3 is aligned with the target long object 1. Thereafter, the end of the elongated object 1 is gripped by the fingers 22 from above, and the gripping portion 13 is returned along the rail 18, so that the elongated object 1 can be pulled out from the storage shelf 4 onto the rollers 21. After pulling out the long object 1 onto the roller 21, the support section 1
2 is raised and lowered, the frame 10 is moved sideways, and the frame 10 is aligned with the loading platform of the transport vehicle 8. Thereafter, by pushing out the finger 22 portion by the unloading section 14, the long object 1 is transferred to the roller 2.
1 and is transferred onto the long object 1 on the loading platform or on the railroad ties. In the above-described embodiment, the elongated object 1 is loaded and unloaded onto the roller 21 by moving the gripping section 13 by the unloading section 14. It is also possible to provide a separate unloading section 14 of the same type for retracting.

As detailed above, the present invention has the following effects compared to conventional warehouses.

That is, [a] The storage shelf has a structure that has a high storage density and is advantageous in terms of strength, and the shelf is provided with a loaf or the like that can be easily taken in and out, so that workability is good. 'b- Since the long objects stored in the storage shelves are taken in and out from the end surface in the depth direction, the moving distance of the long object handling device is shortened.
The structure becomes simpler.

tc' With the configuration of 'b' above, the long object only moves in its longitudinal direction when it is taken in and out, so drive control is facilitated and the cycle time is shortened.

'd} According to the present invention, long objects can be directly loaded and unloaded from the loading platform of a truck or the like, so there is no need for pre-treatment before taking them into or out of a storage warehouse.
