As a result, as the support body 10 is formed out of a material having flexibility, a concentration load in the case of a roll shaped work having been supported, can be made small, and the damage of the work is prevented, and the improvement of quality is attempted.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial Application Field) The present invention relates to an improvement of a three-dimensional automatic warehouse with a set of cantilevers.

(Prior Art) Conventionally, there have been many three-dimensional automated warehouses equipped with cantilevers for the purpose of storing roll-shaped workpieces such as paper rolls.
It is being adopted. This three-dimensional automatic warehouse with cantilevers is designed to transfer roll-shaped workpieces between shelves made by supporting cantilevers with pillars using a movable stacker crane equipped with forks that can move up and down and take in and out. It is composed of

FIG. 5 is a side cross-sectional view showing an example of the structure of the shelf portion of this type of cantilever-equipped three-dimensional automated warehouse. In FIG. 5, the shelf is constructed by supporting a horizontal cantilever 1 made of C-shaped steel or the like with a vertical column 2 made of C-shaped steel or the like. Further, the work receiving portion of the cantilever 1 is equipped with a ■-shaped work receiving metal 3, and a roll-shaped work such as a paper roll 4 is placed on the work receiving metal 3.
is placed and stored. Furthermore, the workpiece 4 is
The work receiving part of the fork 5 of the stacker crane that transfers the work is also equipped with a V-shaped work receiving metal part 6, similar to the shelf part.
is provided.

However, in a multi-level automatic warehouse having such a shelf configuration in the shape of a ■ character, the contact area between the workpieces 4 when placed on the workpiece holder 3.6 is small. A concentrated load is applied to the contact surface of the workpiece 4, and especially delicate workpieces such as paper rolls are dented or stretched, which adversely affects the quality of the workpiece 4 being stored.

On the other hand, FIG. 6 is a side cross-sectional view showing another example of the structure near the shelves in the cantilever-equipped three-dimensional automatic warehouse. As in the case of FIG. 5, the shelf is constructed by supporting the cantilever 1 in a horizontal state with a vertical column 2. Further, the work receiving portion of the cantilever 1 is provided with an arc-shaped work receiving metal fitting 7, and a roll-shaped work 4 such as a paper roll is placed and stored on the work receiving metal fitting 7. Furthermore, the work receiving part of the fork 5 of the stacker crane that transfers the work 4 at the RL with the shelf part is also provided.
Similar to the shelf section, an arc-shaped workpiece holder 8 is provided.

In a multi-level automatic warehouse having such an arc-shaped shelf structure, the diameter of the workpiece 4 is constant and the workpiece holder 7.8 is configured to match the diameter. It is possible to avoid excessive concentrated loads on the contact surfaces.

However, since workpieces of various diameters coexist, this type of workpiece is not practical.

(Problems to be Solved by the Invention) As described above, in conventional multilevel automated warehouses, concentrated loads are applied to the contact surfaces of the workpieces during storage, causing dents, elongation, etc. There was a problem in that it had a negative impact on the quality of the product.

An object of the present invention is to provide a three-dimensional automatic warehouse that can improve the quality of workpieces by reducing the concentrated load applied to roll-shaped workpieces, thereby eliminating the occurrence of dents, elongation, etc. of stored objects. Our goal is to provide the following.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention provides a fork that can be moved up and down and taken in and out between a shelf formed by supporting a cantilever with a pillar. In a three-dimensional automatic warehouse equipped with a cantilever set configured to transfer roll-shaped workpieces using a mobile crane, at least the cantilever workpiece receiving section or the fork workpiece receiving section is composed of a flexible support member.

(Function) Therefore, in the three-dimensional automatic warehouse of the present invention, by configuring at least the cantilever workpiece receiving portion of the cantilever workpiece receiving portion or the fork workpiece receiving portion from a flexible support member, It becomes possible to reduce the concentrated load applied to the workpieces that are stored.

(Example) The present invention will be described below with reference to an example shown in the drawings.

1 and 2 show an embodiment of the present invention,
FIG. 1 is a side sectional view showing an example of the configuration near the shelves in a cantilever-equipped three-dimensional automated warehouse, and FIG. 2 is a front view thereof. Note that in FIGS. 1 and 2, the same parts as in FIGS. 5 and 6 are designated by the same reference numerals.

In FIGS. 1 and 2, the shelf is constructed by supporting a horizontal cantilever 1 with a vertical column 2.

In addition, a pair of supporting hardware 9 is fixed to the work receiving part of the cantilever 1, and both ends of a support 10 are fixed between the pair of supporting hardware 9, and a paper roll is placed on the support 10. A roll-shaped workpiece 4 such as the above is placed and stored. On the other hand, a pair of supporting metal fittings 11 are also fixed to the work receiving part of the fork 5 of the stacker crane that transfers the work 4 to and from the shelf part, as well as the shelf part. Both ends of a support 12 are fixed between the hardware 11. Here, the support 10.degree. 12 is made of a flexible material such as a steel band or a cloth band (or a combination of several sheets of these).

3 and 4 are a plan view and a side sectional view, respectively, showing a configuration example of a cantilever complete three-dimensional automatic warehouse to which the shelves and forks described in FIGS. 1 and 2 are applied. In addition,
In FIGS. 3 and 4, the same parts as in FIGS. 1 and 2 are designated by the same reference numerals.

In FIGS. 3 and 4, a rail 13 is laid in approximately the center of the warehouse, and a stacker crane 14 can freely run on this rail 13. It can be moved up and down in any direction,
It also includes a fork 5 that can be freely taken in and out in the direction of the shelf.

Further, on both sides of the stacker crane 14, a plurality of the above-mentioned shelf sections each having a cantilever 1 supported by a pillar 2 are arranged along the traveling direction thereof.

Next, the operation of this embodiment will be explained.

In FIGS. 3 and 4, when the work 4 placed and stored on the shelf support 10 is taken out by the stacker crane 14, the stacker crane 14
Since there is no workpiece 4 on the fork 5, the stacker crane 14 is moved to the target shelf, and the fork 5 is raised and lowered to determine the position. At this time, the elevating position of the fork 5 is somewhat lower than the shelf. Next, in this state, the fork 5 is taken out toward the shelf, and then the fork 5 is raised a little, the work 4 is received from the shelf, and the fork 5 is retracted, thereby completing the unloading operation of the work 4.

On the other hand, aft is placed on the fork 5 of the stacker crane 14.
When the workpiece 4 that is being stored is placed in the support 1° of the shelf section, the operation is the reverse of the unloading operation.

That is, in this case, the stacker crane 14 with the work 4 placed on the fork 5 is driven to the target shelf, and the fork 5 is raised and lowered to determine the position. At this time, the elevating position of the fork 5 is somewhat higher than the shelf. Next, take out the fork 5 toward the shelf in a bent state, then lower the fork 5 a little, place the work 4 on the fork 5 on the shelf, and retract the fork 5. The input Wi operation is completed.

As described above, in this embodiment, the roll-shaped workpiece 4 is moved between the cantilever 1 and the shelf formed by supporting the pillar 2 by the movable stacker crane 14 equipped with the fork 5 that can be raised and lowered and taken in and out. In a three-dimensional mortar e warehouse i of a set of cantilevers, which is configured to transfer a set of cantilevers, the workpiece receiving portion of the cantilever 1 and the workpiece receiving portion of the fork 5 are supported by a support 1o made of a flexible steel band or the like.
.

It is composed of 12 parts.

Therefore, when a roll-shaped workpiece 4, which is a stored object, is placed on the shelf or fork 5, the contact area between the workpiece 4 and the workpiece receiving part of the shelf or the fork 5 becomes large. The concentrated load applied to the workpiece 4 can be reduced. This eliminates the occurrence of dents, elongation, etc. of the workpiece 4, especially when storing delicate workpieces such as paper rolls for a long period of time.
This makes it possible to improve the quality of In addition, since the workpiece receiving portion of the shelf section on which the rolled workpiece 4 that is stored is placed and the workpiece receiving portion of the fork 5 are flexible, they are sufficient for handling various workpieces with different diameters. It can be applied to a very practical warehouse. Furthermore, since the workpiece receiving section of the shelf section on which the rolled workpiece 4 that is stored is placed and the workpiece receiving section of the fork 5 are flexible parts, the workpiece receiving section of the shelf section or the workpiece receiving section of the fork 5 is flexible. When the workpiece 4 is placed on the workpiece receiving section, the workpiece receiving section of the shelf or the fork 5
Since the contact area between the workpiece receiving part and the workpiece 4 is increased, the workpiece 4 will not roll, and the workpiece 4 will be
can be stored in a stable state.

In the above embodiment, both the work receiving part of the cantilever 1 and the work receiving part of the fork 5 are made of flexible supports, but the time during which the work 4 is placed on the fork 5 is normally Since it is short in the case of , the initial objective of the present invention can be achieved even if only the work receiving portion of the cantilever 1 is constructed of a flexible support.

[Effects of the Invention] As explained above, according to the present invention, at least the cantilever workpiece receiving portion of the cantilever workpiece receiving portion or the fork workpiece receiving portion is configured with a flexible support member, so that the roll It is possible to provide a three-dimensional automatic warehouse that can reduce the concentrated load applied to shaped workpieces, eliminate the occurrence of dents, elongation, etc. of stored wares and ribs, and improve the quality of the workpieces.
