Japanese Patent Application Laid-Open No. 2004-27815

However, in the vibration damping structure of the frame disclosed in Patent Document 1, since the extremely low-strength steel column constituted by the lowermost yielding steel at the lowermost portion of the column in the frame is compared with the frame of the ordinary column without the ultra- There is a problem that the frame strength is lowered.

In other words, although the frame is originally required to have strength against an earthquake, a portion having a low strength is installed in the frame so as to absorb the energy of the great earthquake, so that a decrease in the strength of the frame as a whole can not be avoided.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is an object of the present invention to provide an apparatus for efficiently absorbing seismic energy by a vibration damping member without causing a decrease in strength of a main frame constituting a main frame of a receiving shelf. And to provide a vibration damping structure of a receiving rack that exhibits sufficient vibration damping performance.

(Mode for carrying out the invention)

(1st embodiment)

Hereinafter, the damping structure of the storage shelf which concerns on 1st Embodiment is demonstrated with reference to drawings.

This embodiment is an example which applied the damping structure of a storage shelf to the storage shelf of an automatic warehouse.

1, the automatic warehouse 10 includes a plurality of receiving shelves 11, a stacker crane 13 for reciprocating on a rail 12 provided between the receiving shelves 11, And a ground control panel C as an apparatus.

The stacker crane 13 as the article transporting device transports the article W between the receiving shelf 11 and the input / output table 14 provided at the end of the receiving shelf 11, The article is transported in order to relocate the article W in the receiving shelf 11. [

The ground control panel C not only performs the entry and exit management and the inventory management of the articles W but also the rearrangement plan of the articles W accommodated in the receiving shelf 11 to perform the I / O management, inventory management, ) To the stacker crane (13).

The traveling direction of the stacker crane 13 is the lengthwise direction of the receiving shelf 11 and the direction in which the articles W are inserted between the stacker crane 13 and the receiving shelf 11 is defined as Rear direction of the receiving shelf 11. [

The weight of the plurality of articles W accommodated in the receiving shelf 11 is the same.

1, the receiving shelf 11 and the stacker crane 13 are fixed to the receiving shelf 11, the stacker crane 13, the receiving shelf 11, the receiving shelf 11, the stacker crane 13, The receiving shelf 11, the receiving shelf 11, the stacker crane 13, and the receiving shelf 11 are arranged in this order.

Each storage shelf 11 is the same structure mutually.

As shown in Fig. 3, in the up-and-down direction and longitudinal direction of the receiving shelf 11, a plurality of article receiving spaces S accommodating the articles W are formed.

As shown in Fig. 2 (a), Fig. 4 and Fig. 5, the receiving shelf 11 is provided with a main frame 15 having a main skeleton of the receiving shelf 11.

The main frame 15 has a pair of main pillar members 16 disposed on the front and rear sides and a main beam member 17 connecting the top portion, the bottom portion and the middle portion of the main pillar member 16 .

The lower end of each main column member 16 is fixed to the bottom surface F. As shown in FIG.

As shown in Fig. 2 (a), in the main frame 15 of the present embodiment, two main spherical surfaces 18 surrounded by the main pillar member 16 and the main beam member 17 are formed, A plurality of lattices 19 are provided on the main spherical surface 18 in the vertical direction.

The lattice 19 is a vertical workpiece for preventing deformation of the main spherical surface 18 and connects the front and rear main column members 16 to be inclined with respect to the main column member 16. [

The main frame 15 is an element mainly responsible for the strength required for the storage shelf 11.

The pillar column 16, the column beam member 17, and the lattice 19 are formed of steel, and the pillar column 16 is a steel pipe.

As shown in Fig. 3, a slave frame 20 is provided adjacent to the main frame 15 in the longitudinal direction of the receiving shelf 11. As shown in Fig.

The slave frame 20 has a pair of slave column members 21 arranged in the front and rear and a slave beam member 22 connecting the upper, lower and intermediate portions of the slave column member 21.

The lower end of each subordinate pillar member 21 is fixed to the bottom surface F. As shown in FIG.

2 (b), two slave spherical surfaces 23 surrounded by the slave column member 21 and the dependent beam member 22 are formed in the slave frame 20. As shown in Fig.

Since the dependent spherical surface 23 is not provided with the lattice 19 on the slave spherical surface 23, the slave spherical surface 23 is easily deformed when receiving an external force in the forward and backward directions as compared with the main spherical surface 18. [

The slave frame 20 has a strength enough to support the article W and has little contribution to the strength of the shelf 11 against earthquake and is remarkably stiff as compared with the main frame 15 small.

The subordinate pillar member 21 and the subsidiary beam member 22 are formed of steel, and the subordinate pillar member 21 is a steel pipe of a smaller diameter than the main column member 16.

3, the main shelf 15 and the subordinate frame 20 are alternately arranged in the longitudinal direction of the receiving shelf 11 in the receiving shelf 11 of the present embodiment.

As shown in Figs. 4 and 5, the main frame 15 is provided with a substantially U-shaped support member 24 fixed to a pair of main pillar members 16. As shown in Fig.

The subordinate frame 20 is provided with a substantially U-shaped support member 25 fixed to a pair of subsidiary post members 21 so as to oppose the support member 24. [

The support members 24 and 25 are members for supporting the article W.

Therefore, in the present embodiment, the article accommodation space S is a space defined by the support members 24, 25 between the main frame 15 and the slave frame 20. [

The receiving shelf 11 includes a horizontal member 16 connecting the main pillar member 16 on the rear side of the main frame 15 and the slave pillar member 21 on the rear side of the slave frame 20. 26).

The horizontal reservoir 26 is formed of a steel material and is horizontally laid on the upper, lower and middle portions of the main column member 16 and the slave column member 21, respectively.

The receiving shelf 11 also includes a horizontal lid member 26 for connecting the main pillar member 16 on the front side of the main frame 15 and the slave column member 21 on the front side of the slave frame 20 .

The two main pillar members 16 sandwiching the subsidiary pillar members 21 and the upper and the lower horizontal crawler members 26 on the front and rear portions of the receiving shelf 11 Thereby forming a vertical spherical surface.

As shown in Fig. 3, a brace 27 is provided diagonally on the rear vertical spherical surface.

Both ends of the brace 27 are respectively connected to the location where the main column member 16 and the horizontal crawfish 26 cross | intersect.

The horizontal crawfish 26 and the brace 27 are elements for improving the strength of the receiving shelf 11.

4, the main frame 15 (not shown) of the support member 24 and the slave frame 20 (not shown) of the support member 25 are shown for convenience of explanation, and the brace 27 ) Have been omitted.

The receiving shelf 11 of the present embodiment is configured such that the uppermost portion of the main frame 15 and the slave frame 20 (the main pillar member 16 and the slave pillar member 21) And an oil damper 28 as a horizontally sandwiched member in the lower part of the main column member 16 and the subsidiary column member 21 of the first and second support members 24 and 25.

The oil damper 28 is horizontally laid between the main frame 15 and the slave frame 20 and extends between the main pillar member 16 and the rear slave pillar member 21, And connects between the main column member 16 and all of the subsidiary column members 21.

That is, the oil damper 28 corresponds to a connecting member for connecting the main frame 15 and the slave frame 20.

The longitudinal direction of the oil damper 28 is inclined with respect to the longitudinal direction of each of the main beam member 17 and the dependent beam member 22 and is inclined with respect to the main spherical surface 18 and the slave spherical surface 23 .

The oil damper 28 is a vibration damping member that damps vibrations and has a structure capable of expanding and contracting in the longitudinal direction by using oil contained in the oil damper 28.

The oil contained in the oil damper 28 absorbs the vibration energy when the oil damper 28 expands and contracts by the compressive force and the tensile force acting upon the oil damper 28 at the time of vibration.

As described above, the receiving shelf 11 of the present embodiment has the vibration damping structure using the oil damper 28 as the vibration damping member in the horizontal strap connecting the main frame 15 and the slave frame 20.

Next, the damping action of the storage shelf 11 which concerns on this embodiment is demonstrated.

When a large earthquake occurs, the receiving shelf 11 wobbles, but the main frame 15 having a sufficient strength and the subordinate frame 20, which is easily deformed as compared with the main frame 15, Different shakes occur.

In the main frame 15 having a large rigidity, the deformation is small and the deformation of the slave frame 20 is easy due to the external force.

In particular, the upper part of the accommodating shelf 11 tends to have a larger shaking compared with the lower part.

Since the oil damper 28 is subjected to a compressive force or a tensile force in response to the swing of the receiving shelf 11 and the main frame 15 and the slave frame 20 are out of phase with each other, .

The oil contained in the oil damper 28 effectively absorbs the earthquake energy.

The oil damper 28 efficiently absorbs the earthquake energy, so that the shaking of the receiving shelf 11 is suppressed.

In the vibration damping structure of the receiving shelf 11 of the present embodiment, as compared with the conventional receiving shelf of which the horizontal strap is made of steel, the amount of displacement, the response acceleration, The shearing force acting on the frame 15 is reduced to about half.

The oil damper 28 absorbs the earthquake energy regardless of the direction of the horizontal shaking in the case where horizontal shaking (horizontal shaking) occurs in that the oil damper 28 is used as the horizontal sanding material.

6 (a) to 6 (c) are top plan views of the uppermost portion of the receiving shelf 11, schematically showing the vibration damping action with respect to the horizontal shaking in different directions, and arrows in the drawing indicate the shaking direction In addition to this, the solid line indicates the state before the deformation, and the two-dot chain line indicates the state after the deformation.

6 (a) shows a case where the receiving shelf 11 horizontally swings in the front-rear direction, Fig. 6 (b) shows a case where the receiving shelf 11 swings horizontally in the longitudinal direction, And the shelf 11 is horizontally shaken at an angle of 45 degrees with respect to the longitudinal direction.

6 (a) to 6 (c), for convenience of explanation, one of the two oil dampers 28 having different inclination directions is referred to as an oil damper 28A and the other is referred to as an oil damper 28B.

In Fig. 6 (a), the slave frame 20 is deformed in the front-back direction because of the horizontal sway of the receiving shelf 11 in the front-rear direction.

With the deformation of the slave frame 20, the oil dampers 28A and 28B expand and contract.

When the slave frame 20 is deformed so as to be inclined forwardly of the original position, when the compression force acts on the oil dampers 28A and 28B and is deformed to be inclined rearward beyond the initial position, the oil dampers 28A and 28B are subjected to a tensile force Lt; / RTI >

In Fig. 6 (b), the horizontal movement of the receiving shelf 11 in the longitudinal direction is shown.

The two main pillar members 16 sandwiching the subsidiary pillar members 21 and the upper and the lower horizontal crawler members 26 at the rear portion of the receiving shelf 11 form vertical spherical surfaces at the rear portion of the receiving shelf 11 And a brace 27 is disposed on the vertical spherical surface of the rear portion.

In the longitudinal transverse swinging of the receiving shelf 11, the rear vertical spherical surface functions as the main spherical surface, and the vertical spherical surface of the entire portion without the brace 27 opposed to the rear vertical spherical surface functions as the slave spherical surface.

Therefore, the frame constituting the entire vertical spherical surface is largely deformed as compared with the frame constituting the rear vertical spherical surface, and the vertical spherical surface of the rear portion and the vertical spherical surface of the entire rear surface are shaken with different phases.

The oil dampers 28A and 28B expand and contract in accordance with the deformation of the frame constituting the entire vertical spherical surface. However, when the frame constituting the entire vertical spherical surface is deformed from the original position toward one side (upper side in the drawing) A compressive force acts on the damper 28A, and a tensile force acts on the oil damper 28B.

When the frame constituting the entire vertical spherical surface is deformed from the initial position toward the other (lower side in the drawing), a tensile force acts on the oil damper 28A, and a compressive force acts on the oil damper 28B.

In Fig. 6 (c), the slave frame 20 is deformed in the direction of the horizontal sway since it is a horizontal sway with an inclination of 45 degrees with respect to the longitudinal direction as indicated by an arrow.

When the slave frame 20 is deformed so as to incline obliquely forward from the original position, a compressive force acts on the oil damper 28A and a slight tension acts on the oil damper 28B.

The tensile force acting on the oil damper 28B is compared with the tensile force of the oil damper 28A while the tensile force acts on the oil damper 28A and 28B when the slave frame 20 is deformed to incline rearward from the original position obliquely It is small.

In any of Figs. 6 (a) to 6 (c), the oil dampers 28A and 28B absorb seismic energy when compressive and tensile forces act.

The vibration damping structure of the receiving rack according to the present embodiment exhibits the following operational effects.

(1) Even when the receiving shelf 11 receives earthquake energy, the main frame 15 and the slave frame 20 are deformed, but the lattice 19 is deformed in comparison with the main frame 15 having the lattice 19 The subordinate frame 20 which does not include the main frame 15 and the subordinate frame 20 are largely deformed so that the main frame 15 and the subordinate frame 20 generate fluctuations of different phases. The oil damper 28 connecting the main frame 15 and the slave frame 20 absorbs earthquake energy and attenuates the vibration of the receiving shelf 11. [ The strength of the main frame 15 is improved as compared with the case where the vibration damper is provided on the main frame 15 because the vibration damper is not provided on the main frame 15 in this embodiment, A sufficient vibration damping performance can be exhibited. As a result, the intensity load on the main frame 15 can be reduced more than the conventional one.

(2) Since the horizontally traveling material is the oil damper 28, the oil damper 28 can efficiently absorb the earthquake energy acting on the receiving shelf 11 regardless of the horizontal shaking direction. In addition, since the oil damper 28 can be restored to the compressive force and the tensile force, the vibration due to the earthquake in the receiving shelf 11 can be efficiently absorbed and attenuated, and the oil damper 28 can be repeatedly .

(3) Since the oil damper 28 is provided at the lower portion of the fourth-stage support members 24 and 25 from the uppermost portion and the uppermost portion of the receiving shelf 11, It is possible to effectively damp the shaking at the upper portion where the shaking is large. Therefore, when compared with a conventional receiving shelf made of a horizontal material made of a steel material, the displacement amount, the response acceleration, and the shearing force applied to the main frame 15 by the shaking at the top of the receiving shelf 11 when the earthquake occurs are reduced to about half can do. As a result, falling of the article W from the receiving shelf 11 can be prevented even if a large earthquake occurs in a state in which the article W is accommodated in the receiving shelf 11. [ It is preferable to provide an oil damper 28 on the upper portion of the receiving shelf 11 which is more than half the height of the receiving shelf 11. [

(4) Even in a conventional receiving shelf, by replacing the horizontal strap connecting the main frame and the subordinate frame with the oil damper 28, a vibration removing function can be added to the existing receiving shelf. In addition, since only the oil damper 28 needs to be replaced, it is easy to convert from a conventional receiving rack to a receiving rack having a vibration damping function. Since the receiving shelf is assembled in the field, the replacement operation to the oil damper 28 is also easy.

(Second Embodiment)

Next, the damping structure of the storage shelf which concerns on 2nd Embodiment is demonstrated.

The second embodiment is different from the first embodiment in that an oil damper is provided on a slave spherical surface in addition to a horizontal member made of a steel material for connecting the main frame and the slave frame.

Other configurations are the same as those of the first embodiment, and the description of the first embodiment is employed for the same configuration, and the codes are used in common.

As shown in Fig. 7, the receiving shelf 31 has a connecting member 32 serving as a horizontal strap connecting the main frame 15 and the slave frame 20. As shown in Fig.

In this embodiment, the connecting member 32 is formed of a steel material.

The slave spherical surface 23 of the slave frame 20 is provided with a pair of oil dampers 33 connecting the front and rear slave column members 21 diagonally.

The pair of oil dampers 33 are provided for each slave spherical surface 23, and the basic structure is the same as that of the oil damper 28 of the first embodiment.

When the dependent frame 20 is deformed in the front-rear direction so that the slave spherical surface 23 is parallelogram-shaped by the earthquake energy when the earthquake occurs, the oil damper 33 is subjected to compressive force Or tensile force acts, and the oil damper 33 expands and contracts greatly.

The oil damper 33, which greatly expands and contracts, efficiently absorbs earthquake energy.

According to the present embodiment, the oil damper 33 provided in the slave frame 20 can attenuate the horizontal swinging of the receiving shelf 11 in the front-rear direction.

It is possible to prevent the article W from dropping forward from the receiving shelf 11 even if a large earthquake occurs in a state in which the article W is accommodated in the receiving shelf 31. [ can do.

In addition, since the pair of oil dampers 33 are disposed on the slave spherical surface 23, the amount of shrinkage of the oil damper 33 due to compression and tension at the time of deformation of the slave frame 20 can be increased And can absorb the earthquake energy efficiently.

(Third Embodiment)

Next, the damping structure of the storage shelf which concerns on 3rd Embodiment is demonstrated.

The third embodiment is different from the first embodiment in that the horizontal straining material connecting the main frame and the subordinate frame is made of a steel having a low yield point.

Other configurations are the same as those of the first embodiment, and the description of the first embodiment is employed for the same configuration, and the codes are used in common.

As shown in Fig. 8, the receiving shelf 41 is provided with a pair of connecting members 42 as horizontal straps connecting the main frame 15 and the slave frame 20. As shown in Fig.

In this embodiment, the pair of connecting members 42 diagonally connect the front and rear main pillar members 16 and the subsidiary pillar members 21, respectively.

The connecting member 42 is formed of a steel having a low yield point.

Low yield point steels are steels with low ductility and high ductility compared to mild steel.

When a large earthquake occurs, the receiving shelf 41 is shaken, and the main frame 15 and the slave frame 20 have different phases from each other.

The connecting member 42 is subjected to a compressive force or a tensile force in accordance with the swinging of the receiving shelf 41. In view of the fact that the main frame 15 and the slave frame 20 have different phases from each other, The connecting member 42 is greatly deformed in accordance with the tension.

The connection member 42 is largely deformed to absorb the seismic energy, and the connecting member 42 absorbs the earthquake energy, so that the shaking in the receiving shelf 41 is attenuated.

According to the present embodiment, since the pair of connecting members 42 are used as the horizontal strapping material, when the horizontal swinging (horizontal swinging) occurs, even if the horizontal swinging direction is any direction, The earthquake energy can be absorbed.

In addition, the deformed connecting member 42 may be replaced with a new connecting member 42.

(Fourth Embodiment)

Next, the vibration damping structure of the receiving rack according to the fourth embodiment will be described.

The fourth embodiment is different from the first embodiment in the configuration of the connecting member connecting the main frame and the subordinate frame and the damper included in the connecting member.

The second member 64 is a metal member fixed to the longitudinal center portion of the dependent beam member 22 and the second member 64 is provided with a pair of second opposing faces (67) are formed.

A damper 68 made of rubber is interposed between the connecting member 65 and the second member 64 provided on the first member 63. The damper 68 has the first opposing face 66 and the second opposing face 64, And is fixed to the second opposing face (67).

The damper 68 is a vibration damping member for damping vibration, and is deformable by the viscoelasticity of the rubber, which is a material.

When the damper 68 is deformed by the action of the compressive force and the tensile force at the time of vibration on the damper 68, the damper 68 absorbs the vibration energy.

In the present embodiment, when vibration in the back and forth direction (shaking in parallel with the main spherical surface 18 and the slave spherical surface 23) occurs in which the slave frame 20 moves relative to the main frame 15 in the forward and backward directions, The connecting member 65 and the second member 64 move relative to each other.

10, the damper 68 is deformed in the front-rear direction in accordance with the relative movement between the connecting member 65 and the second member 64. As shown in Fig.

Therefore, in the point that the direction of vibration in the receiving shelf 61 coincides with the direction of deformation of the damper 68, the vibration in the longitudinal direction is efficiently attenuated and the vibration energy is absorbed by the damper 68 .

The connecting member 62 having the damper 68 is attached to the dependent beam member 22 which is the lower portion of the support member 25 from the top in the order from the top of the slave frame 20 Is installed.

The space between the support member 25 at the fourth stage from the top and the dependent beam member 22 at the bottom of the support member 25 is such that the fork of the article W or the stacker crane 13 exists There is no space.

On the other hand, in the space where the fork of the article W or the stacker crane 13 may exist, there is a first member 63 formed of the same steel as the conventional horizontal warp material.

Therefore, even when the dimension of the damper 68 in the height direction is large, the space in which the fork of the article W or the stacker crane 13 is likely to be present can be reduced by the provision of the damper 68 There is no adverse effect.

The receiving shelf 61 of the present embodiment exhibits the following operational effects.

(5) The receiving shelf 61 receives earthquake energy, and the main frame 15 and the slave frame 20 may generate fluctuations of different phases in the forward and backward directions. In this case, the damper 68 provided on the connecting member 62 connecting the main frame 15 and the slave frame 20 is deformed in the forward and backward direction same as the direction of shaking to efficiently absorb the seismic energy, It is possible to effectively damp the back-and-forth swinging motion of the motor 61. In addition, in the present embodiment, since the vibration damper is not provided on the main frame 15, the strength of the main frame 15 is improved as compared with the case where the vibration damper is provided on the main frame 15, 61 can exhibit sufficient vibration damping performance. As a result, the intensity load on the main frame 15 can be reduced more than the conventional one.

(6) Since the damper 68 is a rubber damper, the manufacturing cost can be suppressed, and the maintenance of the damper 68 is easier than the oil damper 28. Further, since the damper 68 can be restored to the compressive force and the tensile force, it is possible to efficiently absorb and attenuate the vibration caused by the earthquake in the receiving shelf 61, and to use the damper 68 repeatedly .

(7) Since the connecting member 62 having the damper 68 is provided at the lower portion of the fourth-stage support members 24, 25 from the top and the top of the receiving shelf 61, It is possible to efficiently shake the upper portion of the shelf 61 in the upper portion where the shaking is large. Therefore, when compared with a conventional receiving shelf made of a horizontal material made of steel, the amount of displacement, the response acceleration, and the shearing force applied to the main frame 15 by the shaking at the top of the receiving shelf 61 at the time of occurrence of the earthquake are reduced to about half can do. As a result, it is possible to prevent the article W from dropping from the receiving shelf 61 even if a large earthquake occurs in a state in which the article W is accommodated in the receiving shelf 61. It is preferable to provide a connecting member 62 having a damper 68 on the upper portion of the receiving shelf 11 which is more than half the height of the receiving shelf 61.

(8) Even in a conventional receiving shelf, by replacing the horizontal strap connecting the main frame 15 and the slave frame 20 with the connecting member 62 having the damper 68, Can be added. Further, since only the connecting member 62 having the damper 68 is used, it is easy to modify the receiving shelf 61 having the dust removing function from the conventional receiving shelf. Since the receiving shelf 61 is assembled in the field, it is also easy to replace the connecting shelf 61 with the connecting member 62 having the damper 68 itself.

(9) The damper 68 is provided with a space in which the fork of the article W or the stacker crane 13 does not exist and the fork of the article W or the stacker crane 13 In the space, a first member 63 made of the same steel material as the conventional horizontal warp material is provided. Therefore, even when the dimension of the damper 68 in the height direction is large, the space in which the fork of the article W or the stacker crane 13 is likely to be present can be reduced by the provision of the damper 68 There is no adverse effect. As a result, in the case where the receiving shelf having the main spherical surface 18 and the slave spherical surface 23 and having no vibration damping performance is modified to be the receiving shelf 61 of the present embodiment, It may be replaced with the connecting member 62.

That is, between the main frame 15 and the main frame 15, two dependent frames 20 are provided.

A main frame 15 is provided at both ends of the receiving shelf 81 in the mounting direction of the main frame 15 and the slave frames 20. [

The first frame space R1 is formed between the slave frames 20 and the second frame space R2 is formed between the main frame 15 and the slave frame 20. In this embodiment, .

In the first frame space R1 and the second frame space R2, 10 article receiving spaces S are formed in a multi-stage shape.

The accommodation shelf 81 has two first frame spaces R1 and four second frame spaces R2 and 10 article receiving spaces S are formed in the respective frame spaces R1 and R2 , It is possible to accommodate a maximum of 60 articles (W).

13, the receiving shelf 81 includes a horizontal lid member 16 for connecting the main column member 16 on the rear side of the main frame 15 and the slave column members 21 on the rear side of the slave frame 20, (Not shown).

The horizontal crawler member 26 is horizontally laid in the uppermost, lower and middle portions (second stage, fourth stage, sixth stage and eighth stage) of the main column member 16 and the slave column member 21, respectively.

The receiving shelf 81 is provided with a horizontal lid member 26 connecting the main column member 16 on the front side of the main frame 15 and the slave column members 21 on the front side of the slave frame 20 .

The two main pillar members 16 and the upper and lower horizontal lumber members 26 on both sides of the two cantilevered pillar members 21 on the front and rear portions of the receiving shelf 81 are located on the side of the receiving shelf 81 Thereby forming vertical spherical surfaces at the front and rear portions.

As shown in Figs. 12 and 13, a brace 27 is arranged diagonally on the vertical spherical surface of the rear portion of the receiving shelf 81. As shown in Fig.

Both ends of the brace 27 are respectively connected to the location where the main column member 16 and the horizontal crawfish 26 cross | intersect.

The brace 27 is not provided on the vertical spherical surface of the entire receiving shelf 81 in order to allow the stacker crane 13 to move the article W in and out of the article accommodating space S.

The horizontal lag 26 and the brace 27 are elements for improving the strength of the receiving shelf 81. [

In this embodiment, as shown in Fig. 13, a connecting member 62 for connecting the main frame 15 and the slave frame 20 at the top of the receiving shelf 81 is provided.

The first member 63 of the connecting member 62 is fixed to the dependent beam member 22 and the second member 64 is fixed to the main pillar member 16.

The connecting member 62 is provided with a damper 68 and has the same structure as the connecting member 62 of the fourth embodiment.

Accordingly, the damper 68 is deformable in the same direction as the oscillation of the receiving shelf 81 in the longitudinal direction.

The connecting member 62 provided with the damper 68 is attached to the main frame 15 at the intermediate portions (the second, fourth, and eighth tiers) in addition to the uppermost portion of the receiving shelf 81, And the subordinate frame 20 are connected to each other.

In Fig. 12, the location of the connecting member 62 having the damper 68 is indicated by a dotted line.

On the other hand, on the uppermost portion of the receiving shelf 81, there is provided a horizontally sandblasting material 82 connecting between the adjoining frames 20.

The horizontal workpiece 82 is a connecting member not provided with a damper 68 and has the same configuration as the connecting member 32 of the second embodiment.

In the present embodiment, the horizontally sandblasting material 82 is connected between adjacent subordinate frames 20 at the intermediate portions (the second, fourth, and eighth levels) in addition to the uppermost portion of the receiving shelf 81 do.

In FIG. 13, the upper part of the receiving shelf 81 from the sixth-stage article receiving space S is enlarged and shown.

In the receiving shelf 81 of the present embodiment, when the shelf utilization rate is 80 percent (the number of articles is 48), the article W is arranged as shown in Fig.

The heavy load zone HZ is formed by accommodating a large amount of the article W in the first frame space R1 in the receiving shelf 81 and the large load zone HZ is formed in the second frame space R2. (W) are accommodated less and the low-load zone LZ is formed.

Since the slave frame 20 constituting the first frame space R1 in the heavy load zone HZ accommodates many articles W, it is subjected to a large load.

On the other hand, the main frame 15 constituting the second frame space R2 in the low-load zone LZ is a subordinate frame of the heavy load zone HZ ) Receives a load smaller than the load it receives.

More specifically, all of the articles W are accommodated in the two first frame spaces R1 of the receiving shelf 81 to form the heavy load zone HZ.

In the four second frame spaces R2 of the receiving shelf 81, the articles W are accommodated from the lowermost stage to the seventh stage article accommodating space S and the 8th to 10th stage accommodating spaces S are accommodated By doing so, a low-load zone LZ is formed.

In the state in which the article W is accommodated so that the heavy load zone HZ and the low load zone LZ are respectively formed in the receiving shelf 81 in the subordinate frame 20 adjacent to the main frame 15 The subsidiary pillar member 21 of the large load zone HZ receives a large load from the article W on the large load zone HZ side and a small load from the article W on the small load zone LZ side.

That is, the slave column member 21 of the slave frame 20 adjacent to the main frame 15 receives a large load from the side of the large load zone HZ and a large load from the side of the large load zone HZ And receives a small load from the low-load zone LZ side as compared with the load.

In the present embodiment, the load imposed on the slave column members 21 in the pair of slave frames 20 forming the first frame space R1 becomes symmetrical with respect to each other in Fig.

A description will be given of a case where a large earthquake occurs to cause the shake in the receiving shelf 81 but the shake occurs in the forward and backward directions of the article W in and out.

14, the second frame space R2 forming the low-load zone LZ and the first frame space R2 forming the large-load zone HZ are formed, (R 1), a fluctuation in phase is generated.

The heavy load zone HZ and the low load zone LZ can be prevented from being displaced by the arrangement of the articles W in addition to the structural characteristics of the receiving shelf 81 in which the slave frame 20 is swung with a cycle larger than that of the main frame 15. [ The large-load zone HZ has a large deformation compared to the low-load zone LZ.

That is, the fluctuation of the low-load zone LZ is a fluctuation with a small cycle, and the fluctuation of the high-load zone HZ is a fluctuation with a large cycle.

Particularly, the upper portion of the receiving shelf 81 tends to be shaky as compared with the lower portion.

In Fig. 14, the shaking of the main frame 15 having a small shake is not shown, but the shake of the slave frame 20 having a large shake is shown.

The compressive force or the tensile force is applied to the damper 68 of the connecting member 62 along with the swinging of the receiving shelf 81 but the large load zone HZ and the small load zone LZ are in a fluctuating phase And the damper 68 expand / contract greatly.

The damper 68 largely expands and contracts to efficiently absorb seismic energy.

The vibration of the receiving shelf 81 is suppressed by effectively absorbing the earthquake energy by the damper 68.

In some cases, the loading / unloading of the article W may be performed from the state in which the loading zone HZ and the low-load zone LZ are formed on the receiving shelf 81. [

At this time, an empty space S is accommodated in the large-load zone HZ due to the entry and exit of the article W, or the article W is accommodated in the empty space S of the small-load zone LZ , The heavy load zone (HZ), and the low load zone (LZ) may be eliminated.

Even if the heavy load zone HZ or the low load zone LZ is eliminated, the ground control panel C performs the entry and exit management and inventory management of the article W, And rearrangement plan of the article W is carried out.

This rearrangement plan is a plan concerning the arrangement of the articles W for forming the appropriate large-load zones HZ and the low-load zones LZ.

The ground control panel C transmits a command for executing the rearrangement plan of the article W to the stacker crane 13 and the stacker crane 13 moves the article W in response to the instruction.

The heavy load zone HZ and the low load zone LZ are formed again on the receiving shelf 81 by the movement of the article W of the stacker crane 13. [

The receiving shelf 81 according to the present embodiment exhibits the following operational effects.

(10) When an earthquake occurs and shaking occurs in the forward and backward directions (the direction in which the articles W are moved in and out), the swing of the large-load zone HZ becomes large and the swing of the small- The heavy load zone HZ and the low load zone LZ are shaken with different phases from each other. At this time, the connection member 62 connecting the slave frame 20 located between the heavy load zone HZ and the low load zone LZ and the main frame 15 adjacent to the slave frame 20, The damper 68 absorbs the earthquake energy and attenuates the swinging of the receiving shelf 81. The heavy load zone HZ and the low load zone LZ are formed by the arrangement of the articles W in the receiving shelf 81 having the vibration damping function by the main frame 15 and the slave frame 20, The dust-removing performance of the shelf 81 can be further improved.

It is not necessary to provide the damper 68 between the adjoining slave frames 20 which are adjacent to each other, and the damper used for the receiving shelf 81 can be reduced as compared with the first embodiment. As a result, the manufacturing cost of the receiving shelf 81 can be suppressed.

(12) Since the empty article accommodating space S is formed above the second frame space R2, the center of gravity of the accommodating shelf 81 is located below the second frame space R2 in the empty article accommodating space S And the stability of the receiving shelf 81 against wobbling is improved.

(13) Since all the articles W are accommodated in the article accommodating space S in the first frame space R1 of the large-load zone HZ, The shaking can be made larger than the shaking of the low-load zone LZ. It is possible to efficiently absorb the seismic energy by the damper 68 by increasing the difference in the shaking between the heavy load zone HZ and the low load zone LZ.

 (14) A stacker crane 13 for loading and unloading the article W with respect to the article accommodating space S and for transporting the article W, and a stacker crane 13 for transporting the article W to form the large load zone HZ and the low load zone LZ And a ground control panel (C) for controlling the feeding of the wafers (W). Therefore, even when the article W of the receiving shelf 81 is carried in and out, and the heavy load zone HZ and the low load zone LZ are eliminated, the stacker cranes 13 and the ground control panel C The zone HZ and the low-load zone LZ can be formed again.

(Modifications 1 and 2)

Next, Modifications 1 and 2 of the fifth embodiment will be described.

Modification examples 1 and 2 are examples of the receiving shelf 81 in which the first frame space R1 between the dependent frames 20 is made up of three sets.

In Modification 1, the first frame space R1 excluding the first frame space R1 in the center of the first frame space R1 is set as the heavy load zone HZ, the first frame space R1 in the center is set as the heavy load zone HZ, (LZ) as a low-load zone.

Modification example 2 is an example in which all the first frame spaces R1 are set to the heavy load zone HZ.

The configuration of the main frame 15 and the slave frame 20 is the same as that of the fifth embodiment in that the receiving shelf 81 of Modified Example 1 and Modified Example 2 has 50 item receiving spaces S For convenience, codes are commonly used.

15, the receiving shelf 81 is constituted by a main frame 15, a slave frame 20, a slave frame 20, a slave frame 20, a slave frame 20, And the frame 15 in this order.

The receiving shelf 81 has the first frame space R1 between adjacent subordinate frames 20 and the second frame space R2 between the main frame 15 and the subordinate frame 20 And the receiving shelf 81 has three first frame spaces R1 and two second frame spaces R2.

In Modification 1, only the first frame space R1 adjacent to the second frame space R2 is set as the heavy load zone HZ.

In addition to setting the second frame space R2 as the low-load zone LZ, the first frame space R1 fitted in the first frame space R1 is formed in the same manner as the second frame space R2 And is set as the low-load zone LZ.

In Fig. 15, 41 articles W are arranged so that the shelf usage rate is 82 percent.

In Modification 1, the load imposed on the slave column member 21 in the adjacent slave frame 20 of the main frame 15 and the slave load of the slave frame 20 adjacent to the slave frame 20 The load burden of the pillar members 21 is symmetrical with respect to each other in Fig.

In the modified example 1, the horizontally sandblasting material 82 without the damper 68 can be used between the slave frames 20 and the connecting member 62 connecting the main frame 15 and the slave frames 20 It is only necessary to install a damper 68. Therefore, the number of the dampers 68 can be further reduced.

15, dotted lines indicate the positions where the connecting members 62 provided with the dampers 68 are installed.

16, the receiving shelf 81 is constituted by a main frame 15, a slave frame 20, a slave frame 20, a slave frame 20, A slave frame 20, and a main frame 15 in this order.

The receiving shelf 81 has the first frame space R1 between adjacent subordinate frames 20 and the second frame space R2 between the main frame 15 and the subordinate frame 20 And the receiving shelf 81 has three first frame spaces R1 and two second frame spaces R2.

In the modified example 2, all the first frame spaces R1 are set as the heavy load zone HZ, and the second frame space is set as the low load zones LZ.

In Fig. 16, 40 articles W are arranged so that the shelf usage rate is 80 percent.

In the modified example 2, all the first frame spaces R1 are set as the heavy load zone HZ, so that the load bearing received by the slave column members 21 of the slave frame 20 adjacent to the main frame 15 , The load on the heavy load zone HZ side and the load on the low load zone LZ side are borne.

On the other hand, the load imposed by the slave column member 21 of the slave frame 20 adjacent to the slave frame 20 is loaded on the side of the heavy load zone HZ on both sides.

That is, the load on the slave column member 21 of the slave frame 20 adjacent to the main frame 15 and the load on the slave column member 21 of the slave frame 20 which is not adjacent to the main frame 15 ) Are different.

Therefore, in the modified example 2, a damper (not shown) is provided between the slave column member 21 in the slave frame 20 adjacent to the main frame 15 and the slave frame 20 adjacent to the slave frame 20. [ A connecting member 62 having a connecting portion 68 is required.

The slave column members 21 of the slave frame 20 and the slave column members 21 of the slave frame 20 which are adjacent to each other do not overlap with each other on the side of the heavy load zone HZ The load is responsible, and the load burden is the same.

Therefore, only the horizontal frame member 82 that does not include the damper 68 can be used between the slave frames 20 that are not adjacent to the main frame 15.

16, dotted lines denote points where the connecting member 62 provided with the damper 68 is installed.

It is not possible to reduce the number of the dampers 68 as compared with the variation example 1 in the second modification example but the horizontal strap material 82 without the damper 68 can be used between the specific slave frames 20, The number of dampers 68 can be reduced as compared with a receiving shelf in which the main frame 15 and the subordinate frame 20 are alternately arranged.

The present invention is not limited to the above-described embodiments, and various modifications are possible within the scope of the gist of the invention. For example, the following modifications may be made.

In the above-mentioned embodiment, although the damping structure of the storage shelf of this invention was applied to the storage shelf in an automatic warehouse, the storage shelves other than an automatic warehouse may be sufficient.

In the first to fourth embodiments, although the main frame and the dependent frame are alternately arranged in the longitudinal direction of the receiving shelf, the arrangement of the main frame and the dependent frame is not limited thereto. For example, a receiving shelf in which two or more dependent frames are continuous such as a main frame, a slave frame, a slave frame, and a main frame may be used. In this case, the horizontal strap connecting the main frame and the slave frame may be a vibration damping member, Horizontal workpieces to be connected to each other may be made of a steel material. It may also be a receiving shelf in which two or more main frames are continuous.

In the above embodiment, the main spherical surface is a main frame formed by being surrounded by the main column member and the main beam member, and the slave spherical surface is a slave frame surrounded by the slave column member and the dependent beam member. For example, the main spherical surface may be formed by the main pillar member, and the slave spherical surface may also be formed by the subsidiary pillar member. In this case, the supporting member for supporting the article may have the function of the main beam member or the dependent beam member. Alternatively, the inter-shelf connecting members for connecting the receiving shelves to each other at the uppermost position may achieve the function of the main beam member or the dependent beam member.

In the first and third embodiments described above, the horizontally sandpaper is a vibration damping member, but a configuration in which a vibration damping member is provided on a part of the horizontal sand is also possible. For example, brackets may be provided at both ends of the oil damper, and the oil damper may be fixed to the receiving shelf via the bracket. Further, a part of the connecting member may be formed of a steel having a low yield point.

Although the oil damper is used as the damper in the first and second embodiments, the damper may be replaced by, for example, a viscoelastic damper in place of the oil damper. When the damper is a viscoelastic damper, vibration of the rubber material can be deformed by shearing. This case also has the same effect as the oil damper.

In the above-described first embodiment, the oil damper as the vibration damping member is provided at the lower portion (the middle of the main column member and the subsidiary column member) of the fourth-stage support member from the uppermost portion and the uppermost portion of the receiving shelf. The installation location is not limited to this. The installation position of the vibration suppression member is free. In the case of an earthquake, it is preferable to provide a vibration suppression member on the upper portion of the receiving shelf, since the vibration tends to increase as the upper portion of the receiving shelf becomes larger.

In the above-described first embodiment, although the vibration damping members are provided on all the horizontal sheathing members, the vibration damping members may be provided on only a part of the horizontal sheathing members, and the remaining horizontal sheathing members may be made of a steel material. In this case, the number of vibration damping members can be reduced as compared with the first embodiment. Further, the vibration damping member may be provided on the slave spherical surface of the receiving shelf of the first embodiment as in the second embodiment.

In the above-described second embodiment, the vibration damping members are provided on the slave spherical surfaces of all the slave frames. However, some vibration damping members may be provided on the slave frames. In this case, the number of the vibration suppression members can be reduced as compared with the second embodiment.

In the second embodiment, a pair of oil dampers are arranged diagonally on the slave spherical surface of the slave frame. However, as in the modification example shown in Fig. 17, the slave spheres 23 of the slave frame 20 The oil damper 51 may be provided in a zigzag manner in the same manner as the lattice provided on the main spherical surface of the main frame. Also in this case, the same operational effects as those of the second embodiment can be expected.

In the second embodiment, a pair of oil dampers are arranged diagonally on the slave spherical surface of the slave frame. However, even if the oil dampers 33A and 33B are provided as in the modification example shown in Fig. 18 good. The basic structure of the oil dampers 33A and 33B shown in Fig. 18 is the same as that of the oil damper 33 of the second embodiment. 18, the oil dampers 33A and 33B are provided so as to intersect with each other at a position intermediate the uppermost horizontal member 26 and the middle horizontal member 26 in the height direction of the slave column member 21. [ A pair of oil dampers 33A and 33B connecting the front and rear dependent column members 21 are provided diagonally in an upper half and a lower half of the slave spherical surface 23 of the slave frame 20 . When the earthquake occurs, for example, the earthquake energy causes the slave frame 23 to move in the vertical direction (between the horizontal crawler 26 and the middle horizontal crawler 26) The compressive force or the tensile force acts on the oil dampers 33A and 33B with the deformation of the slave frame 20 so that the oil dampers 33A and 33B largely expand and contract. The oil dampers 33A and 33B largely expanding and contracting efficiently absorb the earthquake energy. It is also possible to provide only the lower oil damper 33A without installing the upper oil damper 33B in Fig. Even if the oil damper 33A (and the oil damper 33B) are provided on the slave spherical surface 23 serving as the horizontal horizontal member 26 and the horizontal horizontal member 26 on the receiving shelf 31 good.

In the above embodiment, the sidewall of the slave column member is made smaller in diameter than the transverse sectional area of the main column member, and the slave substrate is not provided with the lattice on the slave sphere, However, the setting of the dependent frame is not limited to this. For example, the diameter dimension of the slave column member is set not to be small, but the diameter dimension of the slave column member and the slave column member may be the same, The thickness of the steel pipe of the column member may be set smaller than the thickness (thickness) of the steel pipe of the column member, and the slave frame may be set more easily deformed than the main frame. In addition, when the dependent frame can be set more easily than the main frame, it is not hindered to install the lattice on the slave spheres in the same manner as the main frame.

In the above embodiment, the distances between the front and rear main pillar members in the main frame and the distances of the subsidiary post members in the slave frame are set to the same distance, but the present invention is not limited thereto. For example, as shown in Fig. 19, as the slave frame 200 in which the distance between the slave column members 21 is shorter than the distance between the main column members 16 in the main frame 15, The slave frame 200 may be made more deformed than the main frame 15. [ In this case, even if the main pillar member 16 and the subsidiary pillar member 21 are the same size, the slave frame 200 becomes more deformable than the main frame 15.

In the fourth and fifth embodiments (including the modified examples), the damper is a rubber damper which is deformed in the longitudinal direction, but it is not limited to a rubber damper. The damper may be, for example, an oil damper which can expand and contract in the longitudinal direction. In this case, the oil damper achieves a function equivalent to that of the rubber damper.
