Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement in a rack warehouse structure having a rack under a seismic isolation device.

[0002]

2. Description of the Related Art As is well known, a rack warehouse is formed to have a suitable length in a vertical direction and a horizontal direction and to have a number of shelves to store a large number of storage items. However, in recent rack warehouses, there is a tendency that a self-propelled stacker crane that loads and unloads items to and from a rack body is set to be controlled by NC.

[0003] As a result, in recent rack warehouses, the size of the rack body tends to be increased as a whole, but at this time, in order to prevent the occupied area from being unnecessarily increased, the rack body is enlarged vertically rather than horizontally. Therefore, the seismic isolation of the rack body which is enlarged in the vertical direction is regarded as important.

There have been various proposals for a rack warehouse structure equipped with a seismic isolation device for realizing the seismic isolation of the rack body.
In a proposal disclosed in Japanese Patent Application No. 10188 (filed on Nov. 5, 1996), a rack body is integrally erected on a gantry, and a seismic isolation device is provided between a lower surface of the gantry and a floor below the gantry. It is going to be arranged.

[0005] In this proposal, a rail extending along the direction in which the racks are arranged is laid on the gantry, and a stacker crane runs on the rail. ing.

Therefore, according to this proposal, the operation of the seismic isolation device prevents the roll from propagating from the floor to the gantry, that is, the rack, thereby realizing a desired seismic isolation. However, on the other hand, there is a possibility that it is pointed out that there are problems in the following points.

That is, first, the rack is integrally erected on the gantry and the rail for running the stacker crane is laid. A so-called large-area base having a plane area sufficient to enable the erecting of a plurality of racks and the laying of rails is provided.

At this time, since the gantry is set in an assembled structure in relation to the seismic isolation device, a large amount of work and time is required when the gantry is provided, and as a result, a desired rack warehouse structure is required. It takes a long construction time to realize it.

That is, since the gantry is supported by the seismic isolation device disposed between the gantry and the floor, when the gantry is assembled by connecting the gantry parts, the overall level of the gantry must be precisely revealed. This requires a lot of work and time.

Not only that, since a large-sized base is provided by connecting a large number of base parts, the amount of the base parts becomes enormous, that is, the amount of materials becomes enormous, which leads to an increase in cost. In addition, since the weight is unnecessarily large, the burden load on the floor surface and the building having the floor surface is increased.

Next, since the seismic isolation device for supporting the gantry is installed on the floor surface, the entire horizontality on the floor surface must be precisely revealed in advance. This floor surface must be formed to have sufficient strength to receive the weight from the gantry side.

If the overall level on the floor is not precise, the entire level must be corrected when installing the seismic isolation device in order to refine the overall level on the gantry. Also, in order to guarantee the strength on the floor surface higher than usual, special considerations must be taken, for example, by laying a steel plate on the floor surface or forming the floor surface in a steel structure.

As a result, in the conventional rack warehouse structure described above, not only a long construction period is required but also it is difficult to reduce the cost in realizing the rack warehouse structure. There is a fear that it is not possible to expect.

The present invention has been made in view of the above-described circumstances, and an object thereof is to shorten a construction period and reduce costs when constructing a rack warehouse. An object of the present invention is to provide a rack warehouse structure that is optimal for expecting an improvement in versatility.

[0015]

In order to achieve the above object, the structure of a rack warehouse structure according to the present invention is basically changed in a vertical and horizontal direction while exhibiting a band shape of an appropriate length in plan view. And a seismic isolation device installed on the floor below the rack and supporting the rack from below, and an interval allowing the movement of the stacker crane. It is assumed that two rows of rack bodies facing each other and arranged in parallel with each other are connected by connecting members formed in a beam shape arranged at appropriate intervals.

At this time, it is assumed that the lower end of the rack body is integrally and continuously connected to a gantry as a reinforcing body formed to have substantially the same area. The apparatus may have an upper end integrally connected to the lower surface of the gantry and a lower end integrally connected to the floor below the gantry.

Further, in the rack storage structure according to the present invention, more specifically, rails which enable a stacker crane to travel are arranged between two rows of racks facing each other and arranged in parallel. At the same time, it is assumed that a rail seismic isolation device is installed on the floor below the rail.

At this time, it is assumed that the rails are arranged on a central upper surface in the longitudinal direction of the connecting member for connecting the two rows of racks or the gantry, and the rail isolation device is provided in the longitudinal direction of the connecting member. May be arranged between the lower surface of the central part of the vehicle and the floor surface, and the seismic isolation device for the rail may be replaced with another seismic isolation mechanism having an equivalent seismic isolation function. good.

The connecting member for connecting the two rows of racks or pedestals is formed in a form divided at the center in the longitudinal direction, and one end is connected to the rack or the pedestal while the other end is connected to the rail. At this time, the rail seismic isolation device may be disposed between the lower surface of the rail and the floor surface, or between the lower surface of the other end of the connecting member and the floor surface. It may be arranged.

[0020]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described based on the illustrated embodiment. As shown in FIGS. 1 and 2, a rack warehouse structure according to an embodiment of the present invention has a rack body. 1, a seismic isolation device 2, and a connecting member 3, and further, a rail 4 and a rail seismic isolation device 5.

The rack body 1 is set so as to have a belt shape of an appropriate length in plan view, and has not only a self-supporting property but also a predetermined mechanical strength while reducing the overall weight. In order to realize the above, it is formed into an assembled support structure using an appropriate shape member and pipe material, and has a large number of shelves partitioned in a vertical direction and a horizontal direction, and stored in each shelf. It is set to allow storage of things.

In the illustrated embodiment, the rack bodies 1 are arranged in a plurality of parallel rows.
By connecting the tops of the racks 1 with head connecting members 11 (see FIG. 1), a group of racks composed of the racks 1 arranged in a plurality of parallel rows is integrated.

Incidentally, a guide rail 12 (see FIG. 1) extending corresponding to the rail 4 described later is held by the head connecting member 11, and the guide rail 12 has an upper end of the stacker crane C. Are movably linked.

The rack body 1 is formed so as to have a predetermined mechanical strength as described above.
In that case, it is preferable that the so-called feet of the rack body 1 are formed robustly.
It is also possible to use a reinforcing structure in which only the lower end of the rack body 1 is made thick.

In the case where the lower end of the rack 1 is thickened and reinforced as described above, a predetermined mechanical strength for connecting the connecting member 3 described later is applied to the lower end of the rack 1. You will have it.

As shown in FIG. 4, a reinforcing plate 13 may be connected to the lower end of the rack body 1 for reinforcement. When the reinforcing plate 13 is provided, a rack of the seismic isolation device 2 described later is used. A place to connect to the body 1 will be secured.

It should be noted that a so-called back-to-back rack 1
The comrades are, of course, connected by an appropriate connection structure, but preferably at this time, rather than being connected to a rigid connection structure by welding or the like, it is preferably connected to a pin connection structure using bolts and nuts. Is preferred.

The seismic isolation device 2 includes a floor F below the rack body 1.
(See FIG. 1) and functions to prevent the roll from propagating from the floor surface F from propagating to the rack 1 while supporting the rack 1 from below, that is, to function as a seismic isolation.

Therefore, the configuration of the seismic isolation device 2 may be freely set, for example, with a laminated rubber plate structure, as long as desired seismic isolation is possible. Is set to a ball bearing structure as shown in FIG.

That is, the seismic isolation device 2 having the ball bearing structure moves the fixed side member 21 fixed to the floor surface F, which is the fixed side, horizontally on the fixed side member 21 via the steel ball 22. And a movable-side member 23 which is mounted so as to be integrally mounted on the rack 1 which is a movable side.

The fixed side member 21 is formed in a disk shape as a whole, has a conical concave portion 21a on the upper surface, and has an annular stopper portion which is a so-called end portion of the conical concave portion 21a on the peripheral portion. 21b.

The conical recess 21a is set in the illustrated embodiment so as to have a straight uphill slope from the center to the outer periphery, and the angle of the uphill slope is set to be equal to that of the recess 21a. For example, the angle is set to about 1 degree.

On the other hand, the movable side member 23 is rotatably mounted on the conical recess 21a via the steel ball 22 and has an upper end integrally connected to a lower end of the rack body 1 which is a movable side. It will be set up.

Incidentally, the steel ball 22 is set to have a large diameter in comparison, and is configured so that the rotation of the large-diameter steel ball 22 is ensured by a large number of small-diameter steel balls 24.

Therefore, in the seismic isolation device 2 shown, when the fixed side member 21 moves laterally due to the floor F side swaying, the steel ball 2
2 rolls over the conical recess 21a, so that the movable-side member 23 is
1 and a relative seismic state is reached, and at this time, the desired seismic isolation is realized.

In the seismic isolation device 2, since the steel ball 22 rolls on the conical recess 21a, compared with the case where the steel ball 22 rolls in the arc-shaped recess.
The relative displacement between the floor F side and the rack body 1 side is uniquely determined irrespective of the natural frequency, and so-called smooth seismic isolation is realized.

The seismic isolation device 2 is, as can be understood from the drawing, basically disposed at the so-called four corners of the rack body 1 and is disposed in the longitudinal direction where the span becomes long. Needless to say, they are arranged in necessary numbers at appropriate intervals.

Although not shown, a damper may be provided at the time of installation of the seismic isolation device 2 so as to enable attenuation during seismic isolation.

When the seismic isolation device 2 is formed of a laminated rubber plate structure, it is advantageous in that the return to the so-called old state after seismic isolation is quicker than in the case of the above-described ball bearing structure. Become.

As shown in FIG. 4, the connecting member 3 integrally connects the two rows of rack bodies 1 facing each other and in parallel with an interval allowing the movement of the stacker crane C. In the illustrated embodiment, it is formed in a beam shape and arranged at appropriate intervals.

In the embodiment shown in the drawing, the connecting member 3 is formed as a so-called single piece, and the wheel W of the stacker crane C is rolled on the central upper surface in the longitudinal direction, which is the horizontal direction in the figure. A rail 4 to be moved is arranged.

Further, the connecting member 3 is a seismic isolation device for rails arranged between the lower surface at the center in the longitudinal direction and the floor surface F, that is, in the present embodiment, the rack described above. It is said that it is supported from below by a seismic isolation device 5 including a seismic isolation device 2 for the body 1.

As described above, by connecting the two rows of rack bodies 1 arranged in parallel so as to share one stacker crane C with the connecting members 3 formed in a beam shape arranged at appropriate intervals,
Similarly, the rack portion between the two rows of rack bodies 1 can be reduced as compared with the conventional rack warehouse structure in which two parallel rows of rack bodies 1 are integrally held by a large area rack.

As a result, the total number of materials can be greatly reduced, and the total weight in the rack warehouse can be significantly reduced. In addition, a large amount of work and time are required to provide the predetermined rack body 1. In addition, it is possible to shorten the construction period and reduce the cost for realizing a desired rack warehouse structure.

It is sufficient that the connecting member 3 is formed in a beam shape. In this case, instead of using an H-shaped steel material as in the illustrated embodiment, for example, a truss beam or the like is used. It may be made of a composite beam.

The connection of the connecting member 3 to the rack body 1 is as follows.
Although it is preferable to use a pin joint structure using bolts and nuts, a rigid joint structure may be formed later by welding or the like.

The rails 4 are provided for running the stacker crane C. The rails 4 extend along the direction in which the racks 1 are arranged. Since the crane C is set to move between the two rows of racks 1 facing each other and arranged in parallel, the crane C is disposed at the center between the two rows of racks 1 facing each other. .

In the illustrated embodiment, the rail 4 is arranged on the upper surface of the center of the connecting member 3 in the longitudinal direction in a state of being integrated by fixed means such as welding. Alternatively, they may be arranged using bolts and nuts.

The configuration of the rail 4 may be freely set as long as the rail 4 can perform a predetermined traveling on the stacker crane C. For example, as shown in FIGS. Or a so-called rail, as shown in FIGS. 6 and 7.

The rail 4 is of course set to a length that allows the stacker crane C to travel. In this case, a so-called long rail may be used. May be connected and used by appropriate means.

By the way, the stacker crane C functions to carry out the items stored in the rack 1 to the outside and to load the external items into the rack 1.

Therefore, of course, the stacker crane C can run with the arrangement of the rails 4,
Since the rail 4 is provided integrally with the connecting member 3, it is not necessary to separately arrange a member for laying the rail 4, so that the number of members can be reduced.

On the other hand, since the rails 4 are integrally provided on the connecting member 3, the rails 4 are formed between the two rows of racks 1 which are formed in a beam shape and are opposed to each other at an appropriate interval and arranged in parallel. The plurality of connecting members 3 forming the material group are so-called integrated, so long as the mechanical strength of the connecting material group can be increased.

The rail seismic isolation device 5 performs a predetermined seismic isolation function while supporting the rail 4 from below.
Therefore, it may be set to a laminated rubber plate structure or the like, or may be set to a ball bearing structure as shown in FIG. 3. In this case, compared to the seismic isolation device 2,
It may be so-called miniaturized.

By disposing the rail seismic isolation device 5, the seismic isolation of the connecting member group including the plurality of connecting members 3 and the isolation of the rail 4 and the stacker crane C running on the rail 4 are achieved. The quake can be executed in synchronization with the seismic isolation in the rack body 1.

In the rack warehouse structure according to this embodiment formed as described above, each rack body 1 which is set to have a band shape in a plan view is individually formed with the seismic isolation device 2 interposed therebetween. Therefore, the level of each rack body 1, that is, the level of the seismic isolation device 2 is set in the rack warehouse as compared with the case of setting the entire level when a conventional large gantry is used. Work and time for construction will be greatly reduced.

At this time, the seismic isolation device 2 only needs to be managed so as to realize the level of the individual racks 1. For example, the entire level of the floor F is not necessarily precisely adjusted. Even if it does not appear, as long as the levelness within the area occupied by one rack body 1 is precise, the predetermined seismic isolation device 2, that is, the rack body 1 can be erected. Become.

Further, the rack bodies 1 each having a horizontal level are individually provided.
Is connected by the connecting member 3, the connecting member 3 and the rack body 1 are so-called bolt-tight structures using stupid holes even when an error may occur in the height between the two parallel rows of rack bodies 1. By being set to be linked, it is easy to deal with.

In the above description, the connecting member 3 is connected to the lower end of the rack body 1. As shown in FIGS. 5, 6, and 7, the rack body 1 is connected to the reinforcing body at the lower end. When the gantry 14 is continuously provided, the connecting member 3 is preferably connected to the gantry 14.

A so-called back-to-back rack 1
When connecting comrades with an appropriate connection structure, this gantry 1
It is preferable to use 4 for connection.

The gantry 14 may have any structure as long as it has a predetermined mechanical strength and supports the rack 1 integrally on the upper surface.
As with the rack body 1, so that the overall weight can be reduced,
For example, it may be formed in an assembling column structure using an appropriate mold member or pipe member, or may be formed in a pallet shape or a frame shape.

In addition, in response to the fact that the rack 1 is set to have a band shape in plan view in the illustrated embodiment, the gantry 14 is also set to have a band shape in plan view. However, in view of the relationship between the seismic isolation device 2 and the connecting member 3 described above, it is not necessary to be set in a band shape in a plan view corresponding to the rack body 1 and may be intermittently arranged.

Incidentally, the pedestal 14 may be replaced by thickening the lower end of the rack body 1 as described above, or by connecting the reinforcing plate 13 to the lower end of the rack body 1 for reinforcement. become.

Therefore, when the gantry 14 is connected to the lower end of the rack body 1, there is a disadvantage that the trouble is increased and the height of the rack body 1 eventually becomes high. Compared to a case where only the lower end of the first member 1 is thickened to form a reinforcing structure, the formation of the rack body 1 is simplified, which is advantageous in that a connecting place of the connecting member 3 is secured.

In the embodiment shown in FIGS. 5, 6 and 7, the upper end of the seismic isolation device 2 is integrally connected to the lower surface of the gantry 14, and the lower end is integrated with the floor F below the gantry 14. Of course, it will be installed continuously.

On the other hand, the connecting member 3 in the embodiment shown in FIGS. 5, 6 and 7, that is, the connecting member 3 connected to the gantry 14 is formed as a single unit. On the other hand, it consists of a so-called two-piece body.

That is, as shown in FIG. 5, the rail 4 is provided therebetween, or as shown in FIGS. 6 and 7, a rail support member 41 is provided therebetween.

As described above, when the connecting member 3 is formed of a two-piece body, so-called error correction, that is, when the connecting member 3 is formed of two pieces, This is advantageous in that when an error occurs in the height of the rack bodies 1 in the row, the correction can be easily performed.

Next, as shown in FIG. 5, the vertical width, that is, the height of the connecting member 3 may be set to be the same as the height of the gantry 14, and as shown in FIGS. , May be set smaller than the height of the gantry 14.

When the height of the connecting member 3 is set to be the same as the height of the gantry 14, it is advantageous in that the strength of the connecting member group including the plurality of connecting members 3 can be increased, and When the height of the connecting member 3 is set smaller than the height of the gantry 14, it is advantageous in that the total number of materials in the connecting member 3 can be reduced.

If the height of the connecting member 3 is set to be smaller than the height of the gantry 14, the so-called strength of the connecting member group may be reduced. In this case, however, as shown in FIG. As described above, it is sufficient to arrange a plurality of seismic isolation devices 5 under the arrangement of the brackets 31 and to support the seismic isolation devices 5 from below.

On the other hand, as shown in FIG.
1 is allowed to bend in the rail 4 supported by the connecting member 3 in the presence of the connecting member 1, that is, exempted when the stacker crane C is set to allow the bending in that portion only when traveling on the rail 4. The quake may be replaced with another seismic isolation mechanism having the same seismic isolation function as the seismic isolation device 2 or 5 described above.

That is, the pillow member 51 extends along the rail 4 on the floor surface F, and the sliding plate 52 is extended on the upper end surface of the pillow member 51 and the rail is located above the sliding plate 52. A metal plate 53 may be provided on the lower end surface of the support member 41 so as to face the sliding plate 52.

In this case, when the stacker crane C travels, the rail 4, that is, the rail support 41 is bent, and the metal plate 53 is in contact with the slide plate 52. Even when the floor F side rolls, a predetermined seismic isolation is realized.

When the stacker crane C travels, considering that the rail 4 bends only at the portion where the stacker crane C is located, the rail 4 is always lowered by the seismic isolation device or similar seismic isolation mechanism. It does not need to be maintained in a state supported by.

Therefore, in the case of the embodiment shown in FIG. 7, it is extremely advantageous in terms of cost as compared with the case where the seismic isolation device 2 or the seismic isolation device 5 is provided. This is advantageous in that it contributes to a reduction in the overall cost.

In the case of the embodiment shown in FIG. 7, the connecting member 3 is formed as a single piece, and the rail supporting member 41 is omitted, and the rail 4 is mounted on the center of the connecting member 3. By setting so that they are arranged, the number of members can be further reduced, and the cost can be further reduced.

[0078]

As described above, according to the present invention, two rows of racks arranged in a band shape in plan view and arranged in parallel are formed in a beam shape arranged at an appropriate interval. Because it is connected with materials, the total number of materials can be greatly reduced compared to the conventional rack warehouse structure in which two rows of racks that are also in parallel are held together by a large-sized stand. Not only can the overall weight be significantly reduced, but also a great deal of work and time is not required to provide a predetermined rack body.

In the present invention, the rack body is
Since it is only necessary to form the individual levelers under the interposition of the seismic isolation device, the horizontality of each rack body, that is, the horizontality setting of the seismic isolation device is the same as that of the case of setting the entire horizontality when the conventional large stand It becomes extremely simple in comparison.

At this time, the seismic isolation device only needs to be managed so as to realize the levelness of each rack body. For example, the overall levelness on the floor surface is not always precisely expressed. However, as long as the levelness within an area occupied by one rack body is precise, a predetermined seismic isolation device, that is, a rack body can be erected.

Further, since the racks having the individual horizontality are connected by the connecting members, even if an error may occur in the height between the two parallel rows of racks, the connecting members and the racks may be connected. By setting the body so as to be connected by a so-called stupid hole-based bolting structure, it is possible to easily cope with the situation.

According to the present invention, since the rail for running the stacker crane is provided integrally with the connecting member, it is not necessary to separately arrange a member for laying the rail. Enables reduction of the total number of components when building a warehouse.

Further, since the rails are provided integrally with the connecting member, the connecting members are formed between two rows of racks which are formed in a beam shape and are opposed to and arranged in parallel at an appropriate interval. A plurality of connecting materials will be so-called integrated,
To that extent, the mechanical strength of the connecting member group can be increased.

As a result, according to the present invention, when constructing a rack warehouse, the construction period can be shortened and the cost can be reduced, and there is an advantage that it is optimal for expecting an improvement in its versatility.
