(Equipment) and a base isolation device that is arranged on a fixed floor and supports a movable floor body are described.

Japanese Patent Laid-Open No. 10-139117

  By the way, since the seismic isolation apparatus as described above is expensive and may require time and labor for construction, it is desired to reduce the number of installations as much as possible. However, if a seismic isolation device is installed only under the rack and a seismic isolation device is not installed under the rail in order to prevent the cargo from falling from the rack when an earthquake occurs, the stacker crane's own weight As a result, the rails and the beams constituting the movable floor body may bend and the accuracy of loading and unloading by the stacker crane may be deteriorated. On the other hand, in order to suppress bending of the rail and the beam constituting the movable floor body, if the beam is enlarged, the cost may be increased.

  Then, an object of this invention is to provide the automatic warehouse which can improve the precision of taking in / out of the load by a stacker crane, suppressing a cost increase.

  The automatic warehouse according to the present invention includes a gantry, a rack disposed on the gantry, a rail disposed on the gantry, a stacker crane that moves on the rail, and loads and unloads the rack, and a lower portion of the rack. A seismic isolation device disposed and supporting the gantry and a support device disposed below the rail and supporting the gantry, wherein the bearing device supports a compressive load acting along a vertical direction and the horizontal direction of the gantry A first strut and a second strut connected to allow movement to the right.

  This automatic warehouse is equipped with a seismic isolation device that suppresses shaking of the gantry when an earthquake occurs, and returns the gantry to its original position when the earthquake subsides, and supports the compressive load acting along the vertical direction. There is applied a bearing device having a first strut and a second strut connected to allow horizontal movement of the first strut. As a result, the support device has a simple structure, but when the gantry deviates from its original position due to the difference in the magnitude of shaking between the floor and the gantry when an earthquake or the like occurs, it moves in the horizontal direction. When an earthquake or the like has subsided and the base has returned to its original position due to the action of the seismic isolation device, it will be in a state of supporting a compressive load acting along the vertical direction. Since such a support device is disposed below the rail, it is possible to prevent the rail from being bent due to the weight of the stacker crane, for example, without increasing the beam of the gantry. Therefore, according to this automatic warehouse, it is possible to improve the accuracy of loading / unloading of the luggage by the stacker crane while suppressing an increase in cost.

  In the automatic warehouse of the present invention, at least the first strut portion may be attached to the floor or the gantry via a ball joint. As a result, the support device can smoothly move to each state of supporting a compressive load acting along the vertical direction and allowing the movement in the horizontal direction.

  In the automatic warehouse of the present invention, the first tension part includes a first part, and the second tension part includes a second part that abuts the first part when supporting a compressive load, at least in the first tension part. The position of the first portion may be adjustable along the vertical direction. Thereby, since the height of a support apparatus can be adjusted according to the distance between a floor and a mount, installation of the support apparatus between a floor and a mount becomes easy.

  In the automatic warehouse of the present invention, the first strut portion includes a flange screwed into the bolt as the first portion, and the second strut portion accommodates a portion protruding from the flange in the bolt as the second portion. A tube body that abuts against the flange in a state may be included. As a result, it is possible to realize a support device that can move to each state of supporting a compressive load acting along the vertical direction and allowing the movement in the horizontal direction with a simple configuration.

  In the automatic warehouse of the present invention, the gantry extends in the horizontal direction along the horizontal direction and the pair of main beams extending in the direction perpendicular to the rail extension direction, and in the horizontal direction in the rail extension direction, The supporting device may be arranged at a position where each of the pair of main beams intersects with the rail when viewed from the vertical direction. Thereby, it can suppress efficiently that a rail bends by the dead weight of a stacker crane.

In addition, in each figure, the same code | symbol is attached | subjected to the same or an equivalent part, and the overlapping description is abbreviate | omitted.

[First embodiment]
As shown in FIG. 1 and FIG. 2, the automatic warehouse 1 includes a plurality of racks 14, a plurality of racks 11 arranged on each rack 14 and accommodating luggage L, and the loading / unloading of the luggage L with respect to each rack 11. A stacker crane 12 for performing the above operation, and a rail 13 for making the stacker crane 12 movable.

  A plurality of racks 11 are arranged on both sides of the rail 13 along the extending direction of the rail 13. Each rack 11 has a plurality of shelves 15 for accommodating luggage L.

  The stacker crane 12 includes a traveling carriage 16 movable on the rail 13, a pair of masts 17 erected on the traveling carriage 16 along the vertical direction, and a lifting platform 18 that can be raised and lowered along the mast 17. The load L is taken in and out of the shelf 15 of the rack 11. A pallet on which a plurality of loads L are stacked is loaded on the lift 18, and the stacker crane 12 may load and unload the loads L with respect to the shelf 15 of the rack 11 together with the pallets.

  As shown in FIGS. 1 and 3, the gantry 14 includes a pair of main beams 21 extending in a direction perpendicular to the extending direction of the rail 13 along the horizontal direction, and an extension of the rail 13 along the horizontal direction. A plurality of sub-beams 22 extending in the present direction and connecting the pair of main beams 21. The main beam 21 is formed of H steel and supports a compressive load in the vertical direction from the rack 11, the stacker crane 12, and the rail 13. The secondary beam 22 is sandwiched between the pair of main beams 21 and fixes the position of the pair of main beams 21. The sub beam 22 may be connected by being fitted to the main beam 21 or may be connected by being welded. The main beam 21 is not limited to H steel, and may be formed of other steel materials, concrete slabs, or the like. The sub beam 22 can be formed of the same material as that of the main beam 21.

  As shown in FIGS. 2 and 3, a seismic isolation device 31 is disposed below each rack 11 and below the main beam 21. A bearing device 32 is disposed below the rail 13 and below the main beam 21. That is, the bearing device 32 is disposed at a position where the main beam 21 and the rail 13 intersect when viewed from the vertical direction. The seismic isolation device 31 and the support device 32 support compressive loads from the rack 11, the stacker crane 12, the rail 13, and the mount 14.

  The seismic isolation device 31 includes a fixed portion 33 fixed to the gantry 14, a spherical portion 34 attached to a lower portion of the fixed portion 33, and a rotatable spherical portion 34, which is fixed to the floor F and is in contact with the spherical portion 34. And a pedestal 35 including a recessed surface. The spherical portion 34 is usually installed so as to be located at the most depressed portion (lowest portion) of the recessed surface of the pedestal 35, and rolls on the recessed surface of the pedestal 35 in response to shaking such as an earthquake. Thereby, the seismic isolation device 31 prevents the gantry 14 from following the movement of the floor, suppresses the shaking of the gantry 14, and returns the gantry 14 to the original position. At this time, the gantry 14 moves not only in the horizontal direction but also in the vertical direction in accordance with the movement of the spherical portion 34. Although the seismic isolation device 31 in the first embodiment is a ball type, the seismic isolation device 31 may be a damper type, a linear motion guide type, or the like. These seismic isolation devices also suppress shaking of the gantry 14 and return the gantry 14 to its original position.

  As shown in FIG. 4, the rail 13 is disposed on the upper surface portion 21 a of the main beam 21. The support device 32 is disposed between the floor F and the bottom surface portion 21 b of the main beam 21 on the opposite side of the rail 13 across the main beam 21. A rib 21c is provided between the upper surface portion 21a and the bottom surface portion 21b of the main beam 21 to maintain the space between the upper surface portion 21a and the bottom surface portion 21b. In FIG. 4, the rib 21c is provided at a location where the rail 13 and the support device 32 overlap, but the position where the rib 21c is provided is not particularly limited.

  The support device 32 has a first tension part 41 and a second tension part 42. The first and second struts 41 and 42 are connected so as to support a compressive load acting along the vertical direction and allow the gantry 14 to move in the horizontal direction.

  The first strut 41 includes a first ball joint 43, a first bolt 44, and a first flange 45 that is screwed into the first bolt 44. The first ball joint 43 includes a pedestal 43a attached to the floor F and a first spherical portion 43b attached to the pedestal 43a and rotatable. The first bolt 44 is a columnar bolt that extends from the first spherical portion 43 b of the first ball joint 43 toward the second protruding portion 42. The first flange 45 includes a first nut portion 45a that is screwed into the first bolt 44, and an annular first flange portion 45b that is integral with the first nut portion 45a.

  The first bolt 44 is tiltable about the first spherical portion 43 b of the first ball joint 43 as an axis. The position of the first flange 45 in the first bolt 44 can be adjusted to an arbitrary position. The first flange portion 45b is formed of a hard and difficult-to-deform material (for example, steel or the like), and the thickness thereof is a thickness that does not substantially bend even when a load from the stacker crane 12 is applied in the surface direction. That's fine.

  The second projecting portion 42 includes a second ball joint 46, a second bolt 47, a second flange 48 that is screwed into the second bolt 47, and a tubular tube body 49. The second ball joint 46 includes a base 46a attached to the gantry 14 and a second spherical portion 46b attached to the base 46a and rotatable. The second bolt 47 is a columnar bolt that extends from the second spherical portion 46 b of the second ball joint 46 toward the first protruding portion 41. The second flange 48 includes a second nut portion 48a that is screwed into the second bolt 47, and an annular second flange portion 48b that is integral with the second nut portion 48a.

  The second bolt 47 is tiltable about the second spherical portion 46b of the second ball joint 46 as an axis. The position of the second flange 48 in the second bolt 47 can be adjusted to an arbitrary position. The second bolt 47 may have the same shape as the first bolt 44, and the second flange 48 may have the same shape as the first flange 45. The tube body 49 accommodates a portion of the second bolt 47 that protrudes from the second flange 48.

  The tube body 49 has a rectangular tube shape and is large enough to accommodate the first and second bolts 44 and 47 when viewed from the vertical direction and is smaller than the first flange 45 and the second flange 48. . The tube body 49 is formed of a hard material (for example, steel) that is difficult to deform. One end of the tube body 49 is fixed to the second flange 48 and accommodates a portion of the first bolt 41 protruding from the first flange 45 of the first bolt 44. The other ends of the tube body 49 are in contact with the first flange 45 but are not fixed to each other. The tube body 49 of the first embodiment is not limited to a rectangular tube shape, and may be a cylindrical shape or the like.

  As described above, the first flange 45 (first portion) of the first projecting portion 41 and the other end of the tube body 49 (second portion) of the second projecting portion 42 are in contact with each other. Since the first flange 45 is screwed into the first bolt 44, the position thereof is fixed. Since the second flange 48 fixed to the tube body 49 is screwed into the second bolt 47, the position of the tube body 49 is fixed. Therefore, when the first projecting portion 41 and the second projecting portion 42 face each other in the vertical direction, the length of the support device 32 in the vertical direction is fixed. As a result, even if a compressive load due to the stacker crane 12 is applied to the rail 13 and the main beam 21, the support device 32 is disposed immediately below the position where the rail and the main beam 21 intersect with each other. The amount of deflection of the main beam 21 is suppressed.

  Next, the operation of the support device 32 when the gantry 14 is displaced from the original position and returns to the original position will be described with reference to FIG.

  When the floor F is shaken due to an earthquake or the like, the seismic isolation device 31 functions, so that the shaking of the gantry 14 in the horizontal direction is mitigated. That is, since the floor F and the gantry 14 have different magnitudes of shaking, there is a shift in the amount of movement in the horizontal direction between the floor F and the gantry 14. Due to this displacement, the gantry 14 is displaced from its original position, and the inside of the tube body 49 contacts the first bolt 44. When the displacement between the floor F and the gantry 14 is further increased, the first bolt 44 tilts in a predetermined direction around the first ball joint 43 by the force received by the first bolt 44 from the tube body 49. At this time, the second bolt 47 of the second projecting portion 42 also tilts in the direction opposite to the direction in which the first bolt 44 tilts about the second ball joint 46.

  Further, when the displacement between the floor F and the gantry 14 increases, as shown in FIG. 5, the distance between the first ball joint 43 and the second ball joint 46 increases and the gantry 14 moves upward. The first flange 45 and the other end of the pipe body 49 are separated from each other. Note that the gantry 14 moves upward so that the spherical portion 34 of the seismic isolation device 31 is positioned on the end side of the hollow surface of the pedestal 35 due to the large displacement between the floor F and the gantry 14. Because it becomes. As a result, the first tension part 41 is not subjected to the compressive load from the second tension part 42. However, even when the displacement between the floor F and the gantry 14 is further increased as described above, at least a part of the portion of the first bolt 44 protruding from the first flange 45 is in the tube body 49. It is stored in.

  As described above, at least a part of a portion of the first bolt 44 protruding from the first flange 45 is accommodated in the tube body 49. Therefore, when the gantry 14 returns to the original position by the function of the seismic isolation device 31, the tube body 49 contacts the first bolt 44. Thereby, according to the movement of the tubular body 49, the first bolt 44 moves so as to return to the original position. Further, according to the movement of the tube body 49, the second bolt 47 also moves so as to return to the original position. That is, the support device 32 is restored to the same position and the same shape as before the shift when the base 14 is returned to the original position by the action of the seismic isolation device 31 after the gantry 14 is displaced due to the earthquake, and the compression device that operates along the vertical direction. The load is supported.

  The automatic warehouse 1 according to the first embodiment described above includes a seismic isolation device 31 that suppresses shaking of the gantry 14 when an earthquake or the like occurs, and returns the gantry 14 to its original position when the earthquake or the like subsides. And a support device 32 having a first strut 41 and a second strut 42 connected so as to support a compressive load acting along the base 14 and allow the gantry 14 to move in the horizontal direction. As a result, while the support device 32 has a simple configuration, when an earthquake or the like occurs and the gantry 14 is displaced from the original position due to a difference in the swing between the floor F and the gantry 14, the horizontal direction is increased. In a state in which movement is permitted, and when the earthquake or the like has subsided and the gantry 14 has returned to its original position, it is in a state of supporting a compressive load acting along the vertical direction. Since such a support device 32 is disposed below the rail 13, it is possible to prevent the rail 13 from being bent by the weight of the stacker crane 12 without increasing the beam of the gantry 14, for example. Therefore, according to this automatic warehouse 1, it becomes possible to improve the accuracy of loading / unloading of the luggage L by the stacker crane 12 while suppressing an increase in cost.

  As for the support apparatus 32 in the automatic warehouse 1 of 1st Embodiment, the 1st thrust part 41 has the 1st ball joint 43, and is attached to the floor F via this. Moreover, the 2nd strut part 42 has the 2nd ball joint 46, and is attached to the mount frame 14 via this. As a result, the support device 32 can smoothly move to each state of supporting a compressive load acting along the vertical direction and allowing the movement in the horizontal direction.

  In the support device 32 in the automatic warehouse 1 according to the first embodiment, the first tension part 41 includes a first flange 45 (first part), and the second tension part 42 supports the first flange 45 when supporting a compressive load. The tube 49 (second portion) that abuts on the (first portion) is included, and the position of the first flange 45 in the first strut 41 can be adjusted along the vertical direction. Thereby, since the height of the support apparatus 32 can be adjusted according to the distance between the floor F and the mount 14, the installation of the support apparatus 32 between the floor F and the mount 14 becomes easy. In addition, the support device 32 can move to each state of a state of supporting a compressive load acting along the vertical direction and a state of allowing movement in the horizontal direction with a simple configuration.

  In the automatic warehouse 1 according to the first embodiment, the gantry 14 includes a pair of main beams 21 extending in a direction perpendicular to the extending direction of the rail 13 along the horizontal direction, and the rail 13 extending along the horizontal direction. A plurality of sub-beams 22 extending in the direction and connecting the pair of main beams 21, and the support device 32, when viewed from the vertical direction, is connected to each of the pair of main beams 21 and the rail 13. May be arranged at a position where and intersect. Thereby, it can suppress efficiently that the rail 13 bends by the dead weight of the stacker crane 12. FIG.

[Second Embodiment]
The automatic warehouse of the second embodiment and the automatic warehouse 1 of the first embodiment are different in the structure of the support device, and the gantry 14, the rack 11, the rail 13, the seismic isolation device 31 and the like provided in the automatic warehouse 1. The configuration and operation of are the same. Hereinafter, the support device 132 used in the automatic warehouse of the second embodiment will be described with reference to FIG. The bearing device 132 includes a first tension portion 141 and a second tension portion 142 that are coupled to allow movement in the horizontal direction in a different form from the bearing device 32.

  The first strut 141 has a pedestal 143 that contacts the floor F, a first bolt 44 that is attached to the pedestal 143 by welding, and a first flange 45 that is screwed into the first bolt 44.

  Since the pedestal 143 is not fixed to the floor F, the first struts 141 can be easily displaced from the position where they are arranged. Therefore, the first member 151 that covers the periphery of the base 143 with a predetermined interval is fixed to the floor F. The top of the first member 151 is provided with an opening 151a, and a pedestal 143 is disposed below the opening 151a. The first bolt 44 passes through the opening 151 a of the first member 151 and extends toward the second projecting portion 142. The size of the opening 151 a viewed from the vertical direction is larger than the first bolt 44 and smaller than the pedestal 143. Accordingly, the pedestal 143 can move in the space covered by the first member 151, but the pedestal 143 cannot be taken out from the space covered by the first member 151. As a result, the first strut 141 is allowed to move in the horizontal direction, but remains only within a predetermined range and does not deviate greatly from the position where it is disposed.

  The second projecting portion 142 includes a pedestal 146 that contacts the bottom surface portion 21 b of the main beam 21, a second bolt 47 that is attached to the pedestal 146 by welding, a second flange 48 that is screwed into the second bolt 47, A cylindrical tube body 49 that accommodates a portion of the 2 bolt 47 protruding from the second flange 48 is provided. As shown in FIG. 6, the tube body 49 accommodates a portion of the first bolt 144 protruding from the first flange 45.

  Similarly to the base 143, the base 146 of the second projecting portion 142 is not fixed to the base 14. Therefore, the second member 152 having the same shape as the first member 151 that covers the periphery of the base 146 with a predetermined interval is fixed to the bottom surface portion 21 b of the main beam 21. As a result, the second strut 142 is also allowed to move in the horizontal direction, but only within a predetermined range.

  Since the support device 132 of the second embodiment is different from the support device 32 only in the portion fixed to the floor F or the gantry 14, the performance of supporting the compressive load from the gantry 14 side is the same. When the bearing device 132 supports the compressive load, the bearing device 132 and the first member 151 and the second member 152 are separated from each other, so that the first member 151 and the second member 152 are not subjected to the compressive load.

  Next, the operation of the support device 132 when the gantry 14 is displaced from the original position due to an earthquake or the like and returns to the original position will be described with reference to FIG.

  A shift occurs in the amount of movement in the horizontal direction between the floor F and the gantry 14 due to an earthquake or the like. Due to this shift, the tube body 49 contacts the first bolt 44. In addition, the second bolt 47 contacts the second member 152. Further, when the displacement between the floor F and the gantry 14 becomes large, the gantry 14 moves upward, and a part of the pedestal 143 is separated from the floor F by the force received by the first bolt 44 from the tube body 49, so that the first bolt 44 tilts in a predetermined direction. At this time, part of the pedestal 146 is also separated from the gantry 14, and the second bolt 47 tilts in the direction opposite to the direction in which the first bolt 44 tilts.

  When the earthquake is stopped and the gantry 14 returns to the original position by the action of the seismic isolation device 31, the first strut 141 and the second strut 142 also move to return to their original positions. This movement is the same as the movement at the time of return of the support apparatus 32 demonstrated in 1st Embodiment. The pedestal 143 and the pedestal 146 are in contact with the floor F or the bottom surface portion 21b, respectively. The support device 132 also returns to the same or substantially the same position as the original position, and returns to the state of supporting the compressive load from the vertical direction.

  As described above, also in the automatic warehouse according to the second embodiment, the bearing device 132 having the same effects as the bearing device 32 according to the first embodiment is applied. Thereby, also by the automatic warehouse of 2nd Embodiment, there can exist an effect similar to the automatic warehouse 1 of 1st Embodiment.

[Third embodiment]
The automatic warehouse of the third embodiment and the automatic warehouse 1 of the first embodiment are different in the structure of the support device, and the gantry 14, the rack 11, the rail 13, the seismic isolation device 31, and the like included in the automatic warehouse 1. The configuration and operation of are the same. Hereinafter, the bearing device 232 used in the automatic warehouse of the third embodiment will be described with reference to FIGS. 8 and 9. The bearing device 232 includes a first tension part 241 and a second tension part 42. As shown in FIG. 8, a tube 260 is provided on the first strut 241.

  One end of the tube body 260 is fixed to the first flange 45, and the shape of the tube body 260 viewed from the vertical direction is the same as that of the tube body 49. The tube body 260 is housed inside the tube body 49 and is not in contact with the tube body 49 and the first bolt 44. That is, the size of the tube body 260 viewed from the vertical direction is a size that allows the first bolt 44 to be accommodated inside, and is a size that can be accommodated inside the tube body 49. The length of the tube body 260 in the vertical direction is such that the other end of the tube body 260 is not in contact with the second bolt 47 and is longer than the length of the portion of the first bolt 44 protruding from the first flange 45.

  The operation of the support device 232 when the gantry 14 is displaced from the original position due to an earthquake or the like and returns to the original position is the same as the operation of the support device 32 of the first embodiment. However, unlike the support device 32, the support device 232 includes the tube body 260, so that the followability of the first tension part 241 according to the movement of the second tension part 42 is improved. Thereby, the 1st strut part 241 can move to a horizontal direction more smoothly.

  As described above, also in the automatic warehouse of the third embodiment, the support device 232 having the same effects as the support device 32 of the first embodiment is applied. Thereby, also by the automatic warehouse of 3rd Embodiment, there can exist an effect similar to the automatic warehouse 1 of 1st Embodiment.

[Fourth embodiment]
The automatic warehouse of the fourth embodiment and the automatic warehouse 1 of the first embodiment are different in the structure of the support device, and the gantry 14, the rack 11, the rail 13, the seismic isolation device 31 and the like provided in the automatic warehouse 1. The configuration and operation of are the same. Hereinafter, a bearing device 332 having a first tension part 341 and a second tension part 342 used in the automatic warehouse of the fourth embodiment will be described with reference to FIGS. 10 and 11.

  The first strut 341 has a tubular tube 370 that accommodates a portion of the first bolt 44 that protrudes from the first flange 45. One end of the tube body 370 is fixed to the first flange 45, and the other end is fixed to the disk-shaped lid portion 371. Since the tube body 370 is fixed to the first flange 45 screwed to the first bolt 44, the tube body 370 can be adjusted to an arbitrary position of the first bolt 44.

  In the second projecting portion 342, a semi-cylindrical member 372 having an opening on the first projecting portion 341 side is fixed to the second bolt 347. The other end of the semi-cylindrical member 372 is in contact with the lid portion 371 but is not fixed. An elastic member 373 is accommodated in the semi-cylindrical member 372. One end of the elastic member 373 is fixed to the bottom surface of the semi-cylindrical member 372, and the other end of the elastic member 373 is fixed to the lid portion 371.

  The tube body 370, the lid portion 371, and the semi-cylindrical member 372 are formed of the same material as the tube body 49 (a material that is hard and difficult to deform). The diameters of the tubular body 370 and the semi-cylindrical member 372 viewed from the vertical direction may be the same or different, but the diameter of the lid 371 is larger than the diameter of the tubular body 370 and the semi-cylindrical member 372. . In FIG. 10, the elastic member 373 takes the shape of a spring, but is not limited as long as the material or shape exhibits elasticity.

  As described above, the lid portion 371 of the first projecting portion 341 and the semi-cylindrical member 372 of the second projecting portion 342 are in contact with each other. The lid 371 is fixed to the tube 370, and the position of the tube 370 is fixed. Further, as described above, the position of the semi-cylindrical member 372 is also fixed. Therefore, when the first projecting portion 341 and the second projecting portion 342 face each other in the vertical direction, the length of the support device 332 in the vertical direction is fixed. As a result, even if a compressive load due to the stacker crane 12 is applied to the rail 13 and the main beam 21, the support device 332 is disposed immediately below the position where the rail 13 and the main beam 21 intersect with each other. And the deflection amount of the main beam 21 is suppressed.

  Next, the operation of the support device 332 when the gantry 14 is displaced from the original position due to an earthquake or the like and returns to the original position will be described with reference to FIG.

  A shift occurs in the amount of movement in the horizontal direction between the floor F and the gantry 14 due to an earthquake or the like. As a result, the first bolt 44 tilts in a predetermined direction with the first ball joint 43 as an axis. Since the first projecting portion 341 and the second projecting portion 342 are connected by the elastic member 373, the second bolt 347 of the second projecting portion 342 is also connected to the first bolt 44 with the second ball joint 46 as an axis. Tilt in the opposite direction to the tilting direction.

  As the displacement between the floor F and the gantry 14 increases, the distance between the first ball joint 43 and the second ball joint 46 increases as shown in FIG. 11, and the lid 371 and the semi-cylindrical member The other ends of 372 are separated from each other. The elastic member 373 extends, and a part of the elastic member 373 is exposed from the semi-cylindrical member 372.

  When the earthquake stops and the gantry 14 returns to the original position, the first strut 341 moves so as to return to the original position. As described above, since the first tension part 341 is connected to the second tension part 342, the second tension part 342 also moves so as to return to the original position. At this time, a force to be restored by the elastic member 373 is applied, and the elastic member 373 is restored to the same position and shape as before the support device 332 is displaced. Thereby, the support apparatus 332 will be in the state which supports the compressive load which acts along a perpendicular direction.

  As described above, also in the automatic warehouse according to the fourth embodiment, the bearing device 332 having the same effects as the bearing device 32 according to the first embodiment is applied. Thereby, also by the automatic warehouse of 4th Embodiment, there can exist an effect similar to the automatic warehouse 1 of 1st Embodiment.

  The preferred embodiment of the present invention has been described above, but the present invention is not limited to the above embodiment. For example, in the above-described embodiment, the support device is disposed at a position where the main beam 21 of the gantry 14 and the rail 13 intersect, but it is not always necessary to be disposed at this position. Further, for example, the first stretching portion 41 of the first embodiment may be a first stretching portion 441 having a universal joint 451 as shown in FIG. The universal joint 451 is rotatable about a first axis 452 and a second axis 453 that are orthogonal to each other, and the first bolt 444 is tiltable according to the movement of the universal joint 451.

  Further, the support device in the present invention does not need to be restored to the same position and shape before and after the earthquake, and can support the load from the gantry even if there is some deformation or displacement.

  Further, the configuration, the number, the material, and the like of each element are not limited to the configuration, the number, and the material in the above embodiment, and can be changed as appropriate. For example, you may combine suitably the structure of the support apparatus 132 in 2nd Embodiment, and the structure of the support apparatus 332 in 4th Embodiment.
