The transport means 30 also has a plurality of support rollers 32 that rotate horizontally between a support position that supports the tray 8 and the movable deck 10 and a retracted position that does not support the tray 8 and the movable deck 10, a link mechanism 34 that is connected to each of the plurality of support rollers 32 and rotates each support roller 32 in synchronization, and a transport device 36 that transports the tray 8 horizontally. Here, the link mechanism 34 is an example of a rotating mechanism.

[0047] Specifically, the plurality of support rollers 32 provided on the conveying means 30 support the underside 8B of the tray 8 at both longitudinal ends, and are driven to swing horizontally between a support position where the tray 8 rotates in the direction in which the tray 8 is conveyed between the boarding / deboarding chamber 2 and a lift 42 (described later) arranged in the lifting chamber 4, and a retracted position where the support rollers are retracted from the underside 8B of the tray 8, allowing the tray 8 to move up and down between the boarding surface of the boarding / deboarding chamber 2 and a transfer device 50 (described later) installed on the floor of the pit 24. In this embodiment, the support rollers 32 are rotatably provided on a swing arm that is supported by a rotation shaft (not shown) facing the height direction H of the apparatus and swings horizontally, and each support roller 32 is not driven but freely rotates as the tray 8 moves.

[0048] The support roller 32 has a link mechanism 34 for rotating between a support position and a retracted position. The link mechanism 34 is driven by a driving means (not shown) to switch the support roller 32 between the support position where it supports the tray 8 and the retracted position where it does not support the tray 8.

[0049] 5, the conveying device 36 is configured to include conveying rollers 38 that contact both longitudinal ends of the tray 8 and convey the tray 8 in the short direction of the tray 8, a drive device (not shown) that rotationally drives the conveying rollers 38, and an advancing / retracting device (not shown) that moves the conveying rollers 38 back and forth between a contact position where the conveying rollers 38 contact the tray 8 and a spaced position where the conveying rollers 38 are spaced apart from the tray 8. The conveying device 36 drives the conveying rollers 38 in contact with the tray 8, thereby conveying the tray 8 between the boarding / deboarding chamber 2 and the lifting chamber 4. The conveying device 36 also retracts the conveying rollers 38 to the spaced position where the conveying rollers 38 are spaced apart from the tray 8, thereby enabling the tray 8 to move up and down between an upper tray position and a lower tray position in the boarding / deboarding chamber 2.

[0050] (transfer device) 4 and 5, a plurality of transfer devices 50 are installed on the floor surface of the pit 24 of the boarding / deboarding room 2 and on a transport frame 40A provided on the boarding / deboarding room 2 side of the lift column 40 rising from the storage room 6 in the elevator room 4. The transfer devices 50 support the trays 8 arranged in the boarding / deboarding room 2, stacked and spaced apart below the trays 8 arranged on the boarding surface, by transfer rollers 52 that can rotate and transport. Specifically, the transfer devices 50 are arranged on the underside 8B of the trays 8 at positions corresponding to two transport rails (not shown) that are arranged along the shorter side of the trays 8 at a distance from each other in the longitudinal direction.

[0051] The transfer rollers 52 are supported by a rotation shaft along the device depth direction D and are rotatably fixed, and are arranged to be able to transport the trays 8 between the boarding / deboarding room 2 and the lift 42 of the lifting room 4. As a result, the trays 8 are supported by the transfer rollers 52 and can be transported below the boarding surface of the boarding / deboarding room 2 between the boarding / deboarding room 2 and the lift 42 arranged in the lifting room 4. The transport of the trays 8 by the transfer rollers 52 is allowed to be performed in the boarding / deboarding room 2 while the vehicle M is entering or leaving the room.

[0052] (movable deck) 1, 3, and 7, the movable deck 10 is disposed between the tray 8 disposed in the boarding / disembarking compartment 2 and the lifting compartment 4.

The lifting means 16 is rotatably supported on a shaft 16A on the floor side of the pit 24 and rotates by a drive device (not shown). A lifting roller 16B that rotatably contacts a lifting guide member 10D of the movable deck 10 is provided on the free end of the lifting means 16. The movable deck 10 can be raised and lowered by the pivoting action of the lifting means 16 between an upper height where its upper surface 10A is the same as the upper surface 8A of the tray 8, which serves as the loading surface, and a lower height where it does not interfere with the lateral feed rollers 82 and longitudinal feed rollers 84 of the tray 8 when the tray 8, located on the loading surface, is supported by the support rollers 32 and moves between the lifting chamber 4.

[0054] The movable deck 10 is located above Ruto When the tray 8 moves between the boarding / deboarding chamber 2 and the elevator chamber 4, it is moved to a position that allows the movement of the tray 8 located above, and when the tray 8 located below moves between the boarding / deboarding chamber 2 and the elevator chamber 4, it is moved to a position that allows the movement of the tray 8 located below. Specifically, the position on the movable deck 10 that allows the movement of the tray 8 located above is a position below the tray 8 located above, and the position on the movable deck 10 that allows the movement of the tray 8 located below is a position above the tray 8 located below. More specifically, the position on the movable deck 10 that allows the movement of the tray 8 located above is a position below the transport height of the tray 8 located above, and the position on the movable deck 10 that allows the movement of the tray 8 located below is a position above the transport height of the tray 8 located below.

[0055] Furthermore, when the movable deck 10 descends, it does not descend further in the device height direction H than the transfer device 50 having the transfer rollers 52, i.e., it descends only to a position above the conveying height of the tray 8 located below, so there is no need to provide an opening on the upper surface 10A to avoid interference with the transfer device 50 or an opening / closing lid to cover the opening, and the upper surface 10A is made into a flat plate-like body. Furthermore, although the movable deck 10 is described in Figure 1 as having a rectangular shape with one side long and the other short in a plan view, the movable deck 10 is not limited to a rectangle and can have other shapes such as a square or a trapezoid in a plan view.

[0056] [Elevator room] As shown in Figures 2, 3 and 5, the lifting chamber 4 is disposed adjacent to the movable deck 10 side of the boarding / deboarding chamber 2 in the device width direction W, and is connected to the storage section 6. The lifting chamber 4 has four lift columns 40 rising from a storage device 60 installed in the storage section 6, a lift 42 supported on the lift columns 40 by a link chain (not shown) so that it can be raised and lowered, a transport frame 40A provided on the lift columns 40 on the boarding / deboarding chamber 2 side, and a drive unit 49 that drives the link chain so that the lift 42 can be raised and lowered between the lifting chamber 4 and the storage section 6.

[0057] 5, a partition door 22 is provided on the wall separating the boarding / deboarding room 2 and the elevator room 4 so as to be able to open and close along the height direction H of the device. In this embodiment, as an example, the partition door 22 is a three-leaf door so that it can be installed even when the elevator room 4 is located on a low floor or when there is an obstacle such as a beam of the building directly above the partition door 22. In this embodiment, as an example, the partition door 22 is a three-leaf lift-up door so that it can be installed even when the elevator room 4 is located on a low floor or when there is an obstacle such as a beam of the building around the partition door 22. However, the partition door 22 may be a two-leaf or four-leaf or more lift-up door, or may of course be a two-leaf or three-leaf or more side-opening door, depending on the degree of obstacles on the building side.

[0058] (lift) As shown in Fig. 5, the lift 42 has a vertical / horizontal conveying device 44 located at the center of the lift 42 in the device width direction W, which conveys the tray 8 in the device width direction W and the device depth direction D. The vertical / horizontal conveying device 44 shown as an example is provided on the underside 8B of the tray 8 and is arranged to rotate horizontally to correspond to two horizontal feed rails (not shown) provided at a distance along the short side of the tray 8 and one vertical feed rail provided in the center of the long side of the tray 8 along the long side. The vertical / horizontal conveying device 44 is provided on a rotating base that respectively supports two drive rollers 46 so that they can rotate horizontally, and the two rotating bases are connected to a link 48 and rotate horizontally in sync. Here, the lift 42 is an example of an elevator.

[0059] [Main components] Here, the configuration of the main parts of this embodiment will be described with reference to the drawings.

[0060] [Auxiliary roller] As shown in Figures 3, 5 and 6, the elevator chamber 4 is Upward Corresponding to the transportation of the tray 8 located between the boarding / deboarding chamber 2 and the lift 42, Upward The auxiliary rollers 33 support the end of the tray 8 positioned at the position 10a. When the movable deck 10 is lowered and the tray 8 is transported between the support rollers 32 provided in the boarding / deboarding chamber 2 and the lift 42 provided in the lifting chamber 4, the auxiliary rollers 33 Upward The auxiliary rollers 33 support both longitudinal ends of the tray 8 from below. Here, the auxiliary rollers 33 are an example of an auxiliary support member.

[0061] As shown in Figure 8, the upper surface of the auxiliary roller 33 is at the same level as the support roller 32 provided on the conveying means 30 arranged in the boarding and disembarking room 2, and is supported by the lift column 40 of the lift 42. 9 to 11, the auxiliary roller 33 is rotatably mounted on a shaft 33C fixed to the shaft mounting member 33B via a support base 33A on the upper part of a transport frame 40A (see FIG. 5) provided on the upper part of a bracket 40B fixed to the surface of the lift column 40 on the side of the boarding / deboarding room 2 in the device width direction W. The auxiliary roller 33 rotates forward and backward along the device width direction W. The auxiliary roller 33 does not have a drive source and is rotated in response to the transport of the tray 8.

[0062] [Function of main parts] Here, the operation of the main parts will be described with reference to FIGS.

[0063] 12, the auxiliary rollers 33 support the lower surfaces 8E of the end members 8D provided on both ends of the tray 8 (only one end is shown here) to assist the transport of the tray 8 along the width direction W of the device. At this point, the transverse feed rollers 82 provided on the lower surface 8B of the tray 8 are not supported by the lift 42.

[0064] FIG. 13 shows this state as seen from the front. As shown in FIG. 13, the tray 8 is supported by a portion of the support roller 32 and the auxiliary roller 33 and is transported toward the lift 42. The transverse feed rollers 82 provided on the underside 8B of the tray 8 are positioned in front of the rails 42A provided on the lift 42. At this time, the lift 42, without the tray 8 loaded, is stopped at a position slightly above the transport height of the tray 8 by approximately dimension Y. This is because, when the tray 8 or the tray 8 carrying the vehicle M is transported from the lift 42 to the boarding / deboarding compartment 2, the lift 42 is released from the weight of the tray 8 or the tray 8 carrying the vehicle M, and thus moves slightly above the transport height of the tray 8. To accommodate this difference in the level of the transport height, a tapered portion 42B is formed at the end of the rails 42A provided on the lift 42, sloping downward toward the boarding / deboarding compartment 2 in the width direction W of the device.

[0065] 14, the tray 8 is further conveyed toward the lift 42, and the lateral feed rollers 82 provided on the underside 8B of the tray 8 ride on the tapered portion 42B of the rail 42A of the lift 42. At this time, the lift 42 descends slightly to begin to support the weight of the tray 8 or the tray 8 with the vehicle M placed thereon, but the auxiliary rollers 33 remain in a state of supporting the tray 8.

[0066] FIG. 15 shows the tray 8 being further conveyed toward the lift 42. As shown in FIG. 15, when the transverse feed rollers 82 provided on the underside 8B of the tray 8 start to travel on the rails 42A of the lift 42, the undersides 8E of the end members 8D of the tray 8 move slightly away from the upper parts of the auxiliary rollers 33, and the tray 8 is conveyed with the transverse feed rollers 82 provided on the underside 8B of the tray 8 supported by the rails of the lift 42, and the undersides 8E of the end members 8D of the tray 8 supported by some of the support rollers 32 on the side of the tray 8 away from the lift 42. As the tray 8 is conveyed further, the tray 8 is supported by the transverse feed rollers 82 and the auxiliary rollers 33 and conveyed onto the lift 42. Then, when the tray 8 is loaded onto the lift 42, the end members 8D of the tray 8 are released from support by the auxiliary rollers 33. Note that when the tray 8 is conveyed from the lift 42 toward the boarding / disembarking chamber 2, smooth conveyance is similarly achieved, although in the opposite direction.

[0067] As described above, the mechanical parking device 1 according to the first embodiment comprises loading and unloading sections 1, 11 each having a tray 8 for placing a vehicle M thereon, a boarding / deboarding room 2 in which two trays 8 are stacked one on top of the other with a gap between them in the vertical direction, a lift room 4 adjacent to the boarding / deboarding room 2 and in which a lift 42 is disposed which carries one tray 8 and which moves up and down, and a movable deck 10 which is disposed between the tray 8 and the lift room 4 so as to be able to move up and down by a lifting means 16, and the lift 42 is allowed to change its stopping position in accordance with the transport height of the upper tray 8 among the trays 8 disposed in the boarding / deboarding room 2 and the transport height of the lower tray 8 among the trays 8 disposed in the boarding / deboarding room 2, and at each transport height Upward The tray 8 positioned above or the tray 8 positioned below can be transported individually between the boarding / deboarding room 2 and the lift 42, and the lifting room 4 is UpwardCorresponding to the transportation of the tray 8 located between the boarding / deboarding chamber 2 and the lift 42, Upward The tray 8 has an auxiliary roller 33 that supports the end of the tray 8 located at At the same time, the elevator has an elevator-side auxiliary support member that supports an end of the upper tray or an end of the lower tray in response to the transportation of the upper tray or the lower tray between the boarding and disembarking chamber and the elevator. .

[0068] This ensures that the movement of the trays 8 during transport is supported more reliably than when there is a large distance between the support rollers 32 of the boarding / disembarking chamber 2 and the rails 42A of the lift 42, and reduces vibrations and noise when the trays 8 get on and off the lift 42. In addition, the impact of the trays 8 on the components of the lift 42 when they get on and off is reduced, and deformation or deterioration over time of the components of the lift 42 and loosening of the drive mechanism of the lift 42 are reduced.

[0069] The lift chamber 4 is configured to include a lift 42 on which the tray 8 is mounted, and a lift column 40 that guides the lift 42 so that it can move up and down. The auxiliary roller 33 is supported by the lift column 40.

[0070] This allows the auxiliary rollers 33 to be installed with a simpler structure than when the auxiliary rollers 33 are provided on the building side, and suppresses the propagation of vibrations to the building side.

[0071] In addition, the auxiliary roller 33 is Upward A pair of trays are arranged facing each other in a direction intersecting the conveying direction of the tray 8 located at the top.

[0072] This makes the transport of the tray 8 more stable than when the auxiliary rollers 33 are provided only on one side of the tray 8.

[0073] In addition, the auxiliary roller 33 is Upward The tray 8 is supported at both ends from below.

[0074] This simplifies the structure compared to a case where the auxiliary rollers 33 support both ends of the tray 8 from above, and stably supports the weight of the tray when it is being transported.

[0075] In addition, the auxiliary roller 33 is UpwardThe rollers are configured to rotate in the conveying direction of the tray 8 located at the center.

[0076] This allows the edges of the tray to be supported more smoothly and transportation to be stabilized compared to when a sliding member or a gliding member is used.

[0077] Second Embodiment Next, a second embodiment will be described with reference to Figures 16 to 21. The second embodiment differs from the first embodiment in that, in addition to the auxiliary roller 33 described in the first embodiment, a lift-side auxiliary roller 43 is provided on the lift 42. Note that the same components as those in the first embodiment will be described using the same reference numerals.

[0078] [Main components] Here, the configuration of the main parts of this embodiment will be described with reference to the drawings.

[0079] [Lift side support roller] Fig. 16 is a plan view showing an outline of the boarding / deboarding chamber 2 and the lifting chamber 4, showing the lift-side auxiliary roller 43 and the auxiliary roller 33 arranged close to each other. Fig. 17 is a front view of the boarding / deboarding chamber 2 and the lifting chamber 4 shown in Fig. 16. Here, the lift-side auxiliary roller 43 is an example of an elevator-side auxiliary support member.

[0080] The lift-side auxiliary roller 43 is provided on the lift 42, Upward Tray 8 located on downward Corresponding to the transportation of the tray 8 located between the boarding / deboarding chamber 2 and the lift 42, Upward the end of the tray 8 located at downwardThe lift 42 supports the end of the tray 8 located at the position indicated by the arrow 33. The tray 8 is supported at both ends of the tray 8. Specifically, the lift 42 is configured to include a frame body on which the tray is mounted and a lift rod 42C provided at the end of the frame body, and the lift-side auxiliary roller 43 is provided on the lift rod 42C, more specifically, is provided opposite two lift rods 42C, 42C on the boarding / deboarding room 2 side of the multiple lift rods 42C. The lift-side auxiliary roller 43 is provided on the side adjacent to the auxiliary roller 33 described in the first embodiment, Upward Tray 8 located on downward The tray 8 is supported at both ends from below.

[0081] 18 shows a state in which the lift-side auxiliary rollers 43 support the tray 8. The lift-side auxiliary rollers 43 are rotatably mounted on shafts 43A fixed to the lifting rod 42C. The rotation direction of the lift-side auxiliary rollers 43 is the same as that of the auxiliary rollers 33 in the first embodiment, that is, they rotate along the device width direction W. The tray 8 is supported from below by the lift-side auxiliary rollers 43 at the bottom surfaces 8E of the end members 8D provided at both ends of the tray 8. FIG. 18 shows a state in which the transverse feed rollers 82 provided on the bottom surface 8B of the tray 8 are transported on the rails 42A of the lift 42, and the tray 8 is in the process of being loaded onto the lift 42.

[0082] [Function of main parts] The operation of the main parts of this embodiment will be described with reference to FIGS.

[0083] As shown in Figure 19, the tray 8 is supported by the support rollers 32 and transported toward the lift 42, and the lower surface 8E of the end member 8D of the tray 8 is about to be supported by the auxiliary rollers 33. At this time, the lift 42, without the tray 8 loaded thereon, is stopped at a position slightly above the transport height of the tray 8, and therefore the upper surface of the lift-side auxiliary roller 43 is positioned slightly above the upper surface of the auxiliary roller 33 by approximately dimension Y. This is because, when the tray 8 or the tray 8 carrying the vehicle M is transported from the lift 42 to the boarding / deboarding room 2, the lift 42 is released from the weight of the tray 8 or the tray 8 carrying the vehicle M, and therefore moves slightly above the transport height of the tray 8. To accommodate this difference in transport height, the end of the rail 42A provided on the lift 42 is formed with a tapered portion 42B that slopes downward toward the boarding / deboarding room 2 in the device width direction W, as in the first embodiment.

[0084] 20 shows the state in which the tray 8 is further conveyed toward the lift 42 and gets on the lift-side auxiliary rollers 43. As shown in FIG. 20, the lift 42 moves slightly downward to begin supporting the weight of the tray 8 or the tray 8 with the vehicle M placed on it, but the tray 8 is supported by the lift-side auxiliary rollers 43 and moves slightly away from the upper surface of the auxiliary rollers 33.

[0085] FIG. 21 shows the state in which the tray 8 has been transported to the lift 42 and is in the process of being loaded. As shown in FIG. 21, the lift-side auxiliary rollers 43 are positioned slightly higher than the auxiliary rollers 33, so that the transverse rollers 82 provided on the underside 8B of the tray 8 smoothly contact the tapered portion 42B formed on the boarding / deboarding chamber side of the rail 42A when the tray 8 transfers onto the rail 42A of the lift 42. This reduces the impact between the transverse rollers 82 and the rail 42A, thereby suppressing vibration and noise. At this point, the boarding / deboarding chamber 2 side of the tray 8 remains supported by the support rollers 32 (not shown). The tray 8 is then further transported and loaded onto the lift 42. When the tray 8 is transported from the lift 42 to the boarding / deboarding chamber 2 side, the same smooth transport is achieved, although in the opposite direction.

[0086] As described above, in the mechanical parking device according to the second embodiment, the lift 42 is Upward Tray 8 located on downward Corresponding to the transportation of the tray 8 located between the boarding / deboarding chamber 2 and the lift 42, Upward the end of the tray 8 located at downward The lift-side auxiliary roller 43 supports the end of the tray 8 located at the top.

[0087] As a result, compared to when only the auxiliary rollers 33 are provided, the trays 8 are supported smoothly and transported more stably between the boarding and disembarking room 2 and the lift 42.

[0088] The lift 42 includes a frame on which the tray 8 is mounted and a lift rod 42C provided at the end of the frame, and the lift-side auxiliary roller 43 is provided on the lift rod 42C.

[0089] This allows the lift-side auxiliary roller 43 to be provided on the basic member that constitutes the lift 42, compared to a system in which a special member is provided on the lift 42 to arrange the lift-side auxiliary roller 43, resulting in a simple structure and reduced cost.

[0090] In addition, the lift side auxiliary roller 43 is Upward Tray 8 located on downward A pair of trays are arranged facing each other in a direction intersecting the conveying direction of the tray 8 located at the top.

[0091] This stabilizes the transport of the tray 8 compared to when the lift-side auxiliary rollers 43 are provided only on one side of the tray 8.

[0092] The lift-side auxiliary roller 43 is provided on the side of the lift 42 adjacent to the auxiliary roller 33 .

[0093] As a result, compared to when the lift-side auxiliary roller 43 is installed on the side away from the boarding and disembarking chamber 2 of the lift 42, even if an error occurs in the stopping position of the lift 42 at the tray transport level, the transport of the tray 8 between the boarding and disembarking chamber 2 and the lift 42 is smooth and stable, and vibrations and noise when the tray 8 gets on and off the lift 42 are suppressed.

[0094] In addition, the lift side auxiliary roller 43 is Upward Tray 8 located on downward The tray 8 is supported at both ends from below.

[0095] This simplifies the structure compared to a case where the lift-side auxiliary rollers 43 support both ends of the tray 8 from above, and stably supports the weight of the tray when it is being transported.

[0096] The lift-side auxiliary rollers 43 are configured to include rollers that rotate in the direction in which the tray 8 is transported.

[0097] This allows the end of the tray 8 to be supported smoothly and transportation to be stabilized, compared to when a sliding member or a sliding member is used.

[0098] The above describes the embodiments of the present invention by citing the first and second embodiments, but each embodiment is merely an example, and various modifications can be made without departing from the spirit of the present invention. It goes without saying that the scope of the rights of the present invention is not limited to these embodiments.

[0099] For example, while the auxiliary roller 33 has been described as including a roller, it is not limited to this and may have another structure as long as it can support and transport the tray 8. As an example, a sliding member or a sliding member may be used instead of the roller. In this case, the material of the member that comes into contact with the end member 8D of the tray 8 may be a resin material with high sliding or gliding properties.

[0100] Furthermore, although the auxiliary roller 33 has been described as being supported on the lift column, it may be supported on other components that make up the mechanical parking device, or on the building side, for example, on the side of the main body.

[0101] Furthermore, although the auxiliary rollers 33 have been described as supporting the tray 8 from the bottom, this is not limiting and the tray 8 may be supported from the side or top. As an example, the end member 8D of the tray 8 may be a channel member that opens toward the auxiliary rollers 33, with the auxiliary rollers 33 positioned inside the channel member to support the tray 8 from the side. In this case, too, moving members or sliding members may be used instead of rollers.

[0102] Moreover, the above examples are not limited to the auxiliary roller 33 but can also be applied to the lift-side auxiliary roller 43.

[0103] Furthermore, the size (diameter, width, etc.) and cross section of the auxiliary roller 33 and the lift-side auxiliary roller 43 may be any size and shape as long as it is suited to the implementation. [Explanation of symbols]
