  Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. The dimensions, materials, and other specific numerical values shown in the embodiments are merely examples for facilitating understanding of the invention, and do not limit the present invention unless otherwise specified. In the present specification and drawings, elements having substantially the same function and configuration are denoted by the same reference numerals, and redundant description is omitted, and elements not directly related to the present invention are illustrated. Omitted.

  As shown in FIG. 1, the article storage device 1 according to the first embodiment of the present invention includes an upper structure 2 and a lower structure 3 disposed below the upper structure 2 via a connecting portion 4 at least in a horizontal direction. The tray 5 on which articles are placed is movably connected, and is transported in the vertical direction between the upper structure 2 and the lower structure 3 by the lifting device 6.

  The lifting device 6 is supported by the lower structure 3 and is separated from the upper structure 2. Therefore, when the upper structure 2 and the lower structure 3 move in the horizontal direction relatively during an earthquake, damage to the lifting device 6 can be suppressed. On the other hand, after the earthquake, the connecting portion 4 connecting the upper structure 2 and the lower structure 3 is not completely restored to the original state, and a horizontal displacement remains in the upper structure 2 and the lower structure 3. If you want to. In this case, the lifting device 6 supported by the lower structure 3 is in a state of being displaced in the horizontal direction with respect to the upper structure 2. According to the present embodiment, the problem relating to the displacement in the horizontal direction is as follows. It can be solved as described in.

  On the floor of the upper structure 2, an elevator port 7 is formed in accordance with the position of the tray 5 raised by the elevator device 6. In the lower structure 3, a storage chamber 8 for storing articles is formed by a shelf 9 that is partitioned vertically. In the present embodiment, for example, the article is an automobile, the connection portion 4 is a seismic isolation member, and the upper structure 2 and the lower structure 3 are mechanical parking lots. However, this invention is not limited to these, It can apply also to the mechanical warehouse etc. which convey articles | goods other than a motor vehicle.

  As shown in FIGS. 2A to 2C, the lifting device 6 includes a lifting table 10 that moves up and down between the upper structure 2 and the lower structure 3, and a mounting table 11 on which the tray 5 is mounted. And a displacement absorbing mechanism 12 provided between the mounting table 11 and the lifting table 10 and supporting the mounting table 11 on the lifting table 10 so as to be movable in the horizontal direction. The upper structure 2 is provided with a guide member 13, and the mounting table 11 is provided with a guided member 14. The guided member 14 provided on the mounting table 11 engages with the guide member 13 when the elevator 10 is raised to the upper structure 2, and is lowered so that the elevator 10 is separated from the upper structure 2. When released from the guide member 13.

  When the lifting platform 10 is raised to the upper structure 2, the guided member 14 engages with the guide member 13, so that the displacement absorbing mechanism 12 interposed between the mounting table 11 and the lifting platform 10 places the mounting table 14. The mounting table 11 is moved according to the horizontal displacement with respect to the lifting table 10, and the position of the tray 5 placed on the mounting table 11 is adjusted to the appropriate position of the lifting port 7 of the upper structure 2. Thereafter, when the lifting platform 10 is lowered and separated from the upper structure 2, the guided member 14 is detached from the guide member 13, so that the position of the tray 5 can be adapted to the lower structure 3.

  With such a configuration, even if a horizontal shift has occurred between the upper structure 2 and the lower structure 3 after the earthquake, the lifting device 6 can be lifted by moving the lifting platform 10 of the lifting device 6 up and down. The position of the tray 5 placed on the mounting table 11 can be adapted to both the upper structure 2 and the lower structure 3, and the article (e.g., without special maintenance without adding power such as a motor). Cars can be loaded and unloaded. Hereinafter, this embodiment will be described in detail.

  As shown in FIG. 1, the lifting device 6 includes a guide column 15 attached to the lower structure 3 and arranged vertically, and a lifting platform 10 that moves up and down along the guide column 15. As with the elevator, the lifting platform 10 is connected to a balance weight so as to move up and down. For example, as illustrated in FIGS. 2A to 2C, the mounting table 11 is supported on the lifting platform 10 via a displacement absorbing mechanism 12. A tray 5 is placed on the mounting table 11, and an automobile is placed on the tray 5 as an article, for example. The tray 5 is often formed in a rectangular shape when viewed from above. In addition, the raising / lowering apparatus 6 shown in figure is a mere example, and is not limited to this structure.

  The displacement absorbing mechanism 12 supports the mounting table 11 so as to be movable in the horizontal direction on the lifting table 10, and in this embodiment, a cross guide 12a shown in FIG. 3 is used. The cross guide 12 a includes an upper rail 16 attached to the lower surface of the mounting table 11, a lower rail 17 attached to the upper surface of the elevator 10, an upper groove 18 that guides the upper rail 16, and a lower groove 19 that guides the lower rail 17. The guide block 20 is formed. The upper rail 16 and the lower rail 17 are arranged in a horizontal plane orthogonal to each other when viewed from above and parallel when viewed from the side.

  The upper rail 16 is disposed in parallel with one side of the tray 5 placed on the mounting table 11, and the lower rail 17 is disposed in parallel with the other side of the tray 5. The cross guides 12a are disposed at the four corners of the mounting table 11, and support the mounting table 11 on the lifting table 10 in a balanced manner. By this cross guide 12a, the mounting table 11 is movable with respect to the lifting table 10 in the X and Y directions in the horizontal plane. Here, the X direction is a direction parallel to one side of the tray 5 placed on the mounting table 11, and the Y direction is a direction parallel to the other side of the tray 5. The deviation absorbing mechanism 12 is not limited to the cross guide 12a, and may be an XY stage, a slide base, or the like.

  As shown in FIGS. 2A to 2C, the mounting table 11 is provided with a base 11a supported by the lift 10 via a displacement absorbing mechanism 12, and a base 11a via a turning mechanism 11b. And a mounting portion 11c. For example, a rectangular tray 5 for an automobile is placed on the placement portion 11c. The turning mechanism 11b turns the placing portion 11c around the vertical axis, and the upper structure 2 moves forward by turning the tray 5 placed on the placing portion 11c 180 degrees around the vertical axis. The used car can be left ahead. Note that the turning mechanism 11b may be omitted, and the car that has been stored in the front may be left behind.

  A rod 21 extends in the horizontal direction and is attached to the base 11 a of the mounting table 11, and a guided member 14 is provided at the tip of the rod 21. The rod 21 penetrates the rod opening 22 formed in the lifting platform 10. A gap G is set between the rod opening 22 and the rod 21, and the mounting table 11 can move in the horizontal plane with respect to the lifting table 10 within the range of the gap G. Specifically, in FIG. 2C, the mounting table 11 can move in the left-right direction (X direction) with respect to the lifting table 10 by moving the rod 21 in the left-right gap G with the rod opening 22. As the rod 21 moves in the insertion / removal direction of the rod opening 22, the mounting table 11 can move in the drawing back and front direction (Y direction) with respect to the lifting table 10. The rod 21 extends from the base portion 11a of the mounting table 11 to the side (guide member 13 side) through a vertical gap formed between the members constituting the lifting table 10. Good.

  As shown in FIG. 4A, the guided member 14 includes, for example, a catch portion 14a formed in a substantially C shape when viewed from above, and the guide member 13 is engaged with the catch portion 14a. The The guided member 14 only needs to have an opening through which the rod-shaped guide member 13 can be inserted, and is not limited to a C-shape.

  As shown in FIG. 1, the guide member 13 is attached to the upper structure 2, and as shown in FIG. 4A, the guide member 13 is formed along the moving direction (vertical vertical direction) of the lifting platform 10. It has the part 13a and the taper part 13b formed in the lower end. Therefore, even after the earthquake, even if the upper structure 2 supporting the guide member 13 and the lower structure 3 supporting the lifting device 6 are displaced in the horizontal direction, the apex of the tapered portion 13b of the guide member 13 is If the displacement is within a range that can be captured by the catch portion 14a of the guided member 14, the catch portion 14a is engaged with the rod portion 13a, and the position of the tray 5 of the elevating device 6 is changed to the elevating port of the upper structure 2. 7 can be adapted. At this time, the horizontal movement of the mounting table 11 with respect to the lifting table 10 caused by the horizontal shift between the upper structure 2 and the lower structure 3 is allowed by the shift absorbing mechanism 12.

  As shown in FIG. 4A, the rod portion 13a of the guide member 13 is attached to the upper structure 2 via the plate member 13c along the vertical direction, and the strength is increased. Thus, since the rod part 13a is attached to the upper structure 2 by the plate member 13c, the catch part 14a is preferably formed in a substantially C shape so as not to interfere with the plate member 13c. However, when the plate member 13c is omitted and the upper end of the rod portion 13a is attached to the upper structure 2, the catch portion 14a may be formed in a ring shape. 4B, a tapered surface 14b may be provided on the inner surface of the catch portion 14a of the guided member 14 so that the guide member 13 can be easily captured.

  As shown in FIGS. 2A and 2B, when the guided member 14 is detached from the guide member 13, the lifting device 6 restores the mounting table 11 to a predetermined initial position with respect to the lifting table 10. There may be provided a centering mechanism 23 for this purpose. The centering mechanism 23 has a function of adapting the position of the tray 5 mounted on the mounting table 11 to the lower structure 3. That is, after the earthquake, when the guided member 14 is engaged with the guide member 13 in a state where the upper structure 2 and the lower structure 3 are displaced in the horizontal direction, the position of the tray 5 is changed to the upper structure 2. While it can be adapted, the lower structure 3 is shifted. However, after that, when the guided member 14 is detached from the guide member 13, the position of the tray 5 can be adapted to the lower structure 3 by restoring the mounting table 11 to the initial position by the centering mechanism 23.

  For example, as shown in FIG. 5, the centering mechanism 23 includes springs 24 arranged in the gaps at the four corners of the mounting table 11 and the lifting table 10 when the lifting device 6 is viewed from above, and is arranged symmetrically. By doing so, the neutral point of pressing by the spring 24 is set. This neutral point is the initial position of the mounting table 11 with respect to the lifting table 10. The centering mechanism 23 includes the above-described spring 24, a spring case 25 attached to the lifting platform 10, a pressing member 26a biased by the spring 24, a sliding member 26b fixed to the mounting table 11, and the like. The pressing member 26 a has a rounded tip that makes contact with the sliding member 26 b, and holds the mounting table 11 at a neutral point with respect to the lifting platform 10 by contacting the sliding member 26 b with the biasing force of the spring 24. To do.

  The spring 24 may be a leaf spring in addition to the coil spring, and the pad 26 may be provided with a ball that abuts on the side of the mounting table 11. Further, a spring may be provided on the cross guide 12a shown in FIG. Further, a damper may be provided in addition to the spring 24 or instead of the spring 24 to suppress the vibration of the mounting table 11 when the guided member 14 is detached from the guide member 13.

  Next, the operation and effect of the article storage device according to the present embodiment will be described with reference to FIGS. 6 (a) to 6 (c) and FIG. 7.

  In FIG. 6A, after the earthquake, the connecting portion 4 (the seismic isolation member) connecting the upper structure 2 and the lower structure 3 is not completely restored to the original state, and the upper structure 2 and the lower structure There may be a case where the horizontal displacement from the body 3 remains. As described above, when the horizontal structure is shifted between the upper structure 2 and the lower structure 3, when the lifting platform 10 of the lifting device 6 provided in the lower structure 3 is raised to the upper structure 2, The guided member 14 provided on the mounting table 11 of the lifting device 6 is engaged with the guide member 13 provided on the upper structure 2.

  Specifically, as shown in FIG. 4A, since the tapered portion 13b is formed at the lower end of the guide member 13, the apex of the tapered portion 13b of the guide member 13 is the guided member as viewed from above. If the horizontal displacement is within the range included in the 14 catch portions 14a, the guided member 14 is engaged with the guide member 13 by the ascending / descending stage 10 as shown in FIG. 6B. Then, the displacement absorbing mechanism 12 (cross guide 12a) interposed between the mounting table 11 and the lifting table 10 causes the mounting table 11 to cancel the horizontal displacement with respect to the lifting table 10 in the X direction and the Y direction. The position of the tray 5 that is moved in the direction and placed on the mounting table 11 is adapted to the position on the basis of the upper structure 2.

  Therefore, as shown in FIG. 6C, when the tray 5 is moved to the lift 7 of the upper structure 2, the tray 5 can be appropriately disposed at the center of the lift 7. As a result, even if there is horizontal displacement between the upper structure 2 and the lower structure 3, articles such as automobiles can be appropriately placed on the tray 5, and the periphery of the tray 5 and the elevator 7 Since the gap between the two becomes uniform, barrier-free operation can be maintained.

  As shown in FIG. 1, the guide member 13 is formed in a rod shape along the moving direction of the lifting platform 10, and the tapered portion 13 b is formed at the end thereof, so that the upper structure 2 and the lower structure 3 are formed. Even if a horizontal misalignment remains between them, the guided member 14 can be easily captured by the tapered portion 13 b, and the guided member 14 can be easily engaged with the guide member 13.

  As shown in FIG. 4, the guided member 14 has an opening (catch portion 14 a) through which the guide member 13 can be inserted. Therefore, when the lifting platform 10 is raised, the guided member 14 is caught. The guide member 13 is inserted into the portion 14a and is restrained in the horizontal direction, so that the relative position of the mounting table 11 with respect to the upper structure 2 can be stably held. Therefore, when the tray 5 placed on the mounting table 11 is raised to the lift 7 of the upper structure 2, the relative position of the tray 5 with respect to the lift 7 can be stably held at an appropriate position.

  Two or more guide members 13 may be provided at intervals along the lift 7, and two or more guided members 14 may be provided on the mounting table 11 accordingly. In this case, the displacement absorbing mechanism 12 is not limited to the cross guide 12a or the like that guides the mounting table 11 in the X direction and the Y direction in the horizontal plane with respect to the lifting table 10, but the mounting table 11 is positioned in the horizontal plane with respect to the lifting table 10. It is possible to use a slide base that can move in any direction. With two or more sets of guide members 13 and guided members 14, rotation (yawing) around the vertical axis of the mounting table 11 with respect to the lifting table 10 can be suppressed. Instead of the above-described slide table, an XYθ stage having degrees of freedom in the horizontal direction and the rotation direction around the vertical axis may be used.

  FIG. 7 shows a state in which the mounting table 11 is swiveled around the vertical axis with respect to the lifting table 10 by the swivel mechanism 11b in order to allow the car that has entered the front to exit from the same doorway. At this time, it is necessary to move the lifting platform 10 higher than FIG. 6C so that the tray 5 is positioned above the lifting opening 7 of the upper structure 2. Even in this state, since the guided member 14 is engaged with the guide member 13, the reaction force and the inertial force applied to the mounting table 11 when the tray 5 is swung are applied to the guided member 14 and the guide member 13. Can be supported by the upper structure 2, and the automobile placed on the tray 5 can be stably turned.

  Next, when the elevator 10 is lowered from the state of FIG. 6C so as to be separated from the upper structure 2, the guided member 14 is detached from the guide member 13 as shown in FIG. To do. Then, the mounting table 11 is restored to the initial position with respect to the lifting platform 10 by the centering mechanism 23 shown in FIGS. 2A and 2B and FIG. 5, and the position of the tray 5 placed on the mounting table 11 is changed. It is applied to the lower structure 3. That is, when the guided member 14 is detached from the guide member 13, the tray 11 placed on the mounting table 11 is provided with the centering mechanism 23 for restoring the mounting table 11 to a predetermined initial position with respect to the lifting table 10. The position of 5 can be adapted to the lower structure 3. Therefore, as shown in FIG. 1, by lowering the lifting platform 10, the car placed on the tray 5 can be appropriately transferred together with the tray 5 to the shelf 9 of the storage chamber 8 of the lower structure 3. it can.

  Specifically, in the article storage device 1 (mechanical parking lot) according to the present embodiment, a driving roller for transporting the tray 5 in the horizontal direction is provided on the mounting portion 11 c of the mounting table 11. The tray 5 is moved from the placement portion 11c to the shelf 9 of the storage chamber 8 by rotating the drive roller while the lower surface of the tray 5 is in contact with the drive roller. When the article storage device 1 is a distribution warehouse, an arm that expands and contracts in the horizontal direction is provided on the mounting portion 11 c of the mounting table 11, and the tray 5 is moved from the mounting portion 11 c to the storage chamber 8 by this arm. You may make it move to the shelf 9. FIG.

  As described above, even if the horizontal structure is shifted between the upper structure 2 and the lower structure 3 after the earthquake, the guided member 14 is moved up and down when the lifting platform 10 of the lifting device 6 is moved up and down. Since the guide member 13 is engaged and disengaged, the position of the tray 5 placed on the mounting table 11 of the lifting device 6 is adapted to both the upper structure 2 and the lower structure 3. As a result, after an earthquake, articles such as automobiles can be properly loaded and unloaded without special maintenance.

  8A and 8B show a modification of the centering mechanism 23. FIG. The centering mechanism 23 a is provided in place of the centering mechanism 23 shown in FIG. 5. The centering mechanism 23 a is provided on a linear motion actuator mechanism 27 such as an electric cylinder provided on the lifting platform 10 and a telescopic rod of the linear motion actuator mechanism 27. It has a taper pin 28 provided and a taper hole 29 formed in the mounting table 11. Further, a displacement absorbing mechanism 12 (for example, a cross guide 12a) is disposed between the mounting table 11 and the lifting table 10.

  The tapered pin 28 is detached from the tapered hole 29 as shown in FIG. 8A when the guided member 14 is engaged with the guide member 13 as shown in FIG. Accordingly, the mounting table 11 is allowed to move with respect to the lifting table 10 so as to absorb the horizontal shift, and the position of the tray 5 placed on the mounting table 11 is adapted to the upper structure 2.

  Further, the taper pin 28 is engaged with the taper hole 29 as shown in FIG. 8A when the guided member 14 is detached from the guide member 13 as shown in FIG. . As a result, the position of the tray 5 placed on the mounting table 11 is adapted to the lower structure 3. At the same time, since the mounting table 11 is fixed so as not to move with respect to the lifting table 10, the automobile placed on the tray 5 can be moved up and down stably.

  Whether the guided member 14 is engaged with or disengaged from the guide member 13 is determined based on, for example, an output value of a sensor that detects the height of the lifting platform 10. This sensor may be a range switch or a limit switch that detects the height position of the lifting platform 10. Even when this centering mechanism 23a is used, the same effects as the centering mechanism 23 shown in FIG. 4 can be exhibited.

  FIG. 9 shows another modification of the centering mechanism 23. The centering mechanism 23b is provided in place of the centering mechanism 23 shown in FIG. 4, and includes a ball plunger 30 provided on the lifting platform 10, a conical recess receiving portion 31 provided on the mounting table 11, and a mounting. And a pop-out preventing member 32 provided on the mounting table 11. The ball plunger 30 includes a ball 30 a that contacts the conical recess receiving portion 31 and a spring 30 b that presses the ball 30 a against the conical recess receiving portion 31.

  As shown in FIG. 6A, when the guided member 14 is detached from the guide member 13, the ball 30a of the ball plunger 30 is placed at the center of the conical recess receiving portion 31 as shown in FIG. fit. Thereby, the position of the tray 5 placed on the mounting table 11 is adapted to the lower structure 3.

  Further, as shown in FIG. 6C, when the guided member 14 is engaged with the guide member 13, the ball 30a of the ball plunger 30 is in the horizontal direction between the upper structure 2 and the lower structure 3. The position of the tray 5 mounted on the mounting table 11 is adapted to the upper structure 2 by generating a shift from the center of the conical recess receiving portion 31 according to the shift. At this time, the ball 30a rides on the slope portion from the center of the recess of the conical recess receiving portion 31 according to the horizontal displacement between the upper structure 2 and the lower structure 3, but the ball 30a rides on the slope portion. As the spring 30b contracts as it goes up, the height of the tray 5 can be adapted to the elevator 7 and barrier-free can be maintained. Even when this centering mechanism 23b is used, the same function and effect as the centering mechanism 23 shown in FIG. 4 can be exhibited.

  FIG. 10 shows an article storage device 1a according to the second embodiment of the present invention. This article storage device 1a has basically the same configuration as the article storage device 1 according to the first embodiment shown in FIG. 1, and the guided member 14 is placed on the shelf 9 of the storage chamber 8 of the lower structure 3. The difference is that guide shafts 33 and 34 are provided in accordance with the positions. As shown in FIG. 10, when the shelf 9 has two stages, the guide shaft 33 of the upper shelf 9 with which the guided member 14 engages from above and below is formed with tapered portions 35 at the upper and lower ends, A tapered portion 35 is formed only at the upper end of the guide shaft 34 of the lower shelf 9 with which the guided member 14 is engaged only from above.

  With this configuration, when the lifting platform 10 moves according to the position of the exceptional shelf 9, the guided member 14 engages with the guide shafts 33 and 34, so that the shelf 9 is displaced from the lifting device 6 due to the earthquake. Even if it has occurred, the position of the tray 5 is adjusted to each shelf 9. Therefore, the tray 5 can be appropriately transferred to the shelf 9.

  When the shelf 9 has one stage, a tapered portion 35 is formed only at the upper end of the guide shaft 34.
