  As shown in FIGS. 1 to 3, the lift 8 is lifted and lowered by a total of four lifting guides 81 installed in the vertical direction around the hoistway 80 (four corners) and by the guides of these lifting guides 81. A tray support member 82 that supports the tray 5 and moves up and down, and a lift drive device 84 that drives the tray support member 82 up and down are arranged on the path 80 so as to be movable up and down.

  As shown in FIG. 3, the tray support member 82 has an overall height slightly smaller than the height set in the conveyance path 201 or 203 of the one storage level or the tray lifting / lowering space 202, and the width is equal to the conveyance path 201 or 203. 203 or slightly smaller than the width of the tray lifting / lowering space 202, and (this tray support member 82) is located between the upper and lower storage levels 11, 12 or between 12, 13 of the plurality of storage levels 11, 12, 13. In the standby state, both the upper and lower storage tiers 11 and 12 transport paths 201 and tray lifting spaces 202 or the upper and lower storage tiers 12 and 13 tray lifting spaces 202 and transport paths 203 can be opened together. A pair of elevating members 821 having various shapes, and a tray engaging / dismounting unit that is provided on the upper and lower portions of these elevating members 821 so as to be able to advance and retract in and out of the hoistway 80 and that can be engaged with and disengaged from the tray 5. ; And a 83. Here, as shown in FIG. 3 or FIG. 6, each elevating member 821 has a substantially gate shape along the inner circumferences of the upper and left and right sides of the transport paths 201, 203 of the storage layers 11, 12, 13 or the tray elevating space 202. Guide members (guide rollers) 822 that are formed in a shape and engageable with the lifting guide 81 are provided on both sides thereof, and one lifting member 821 can be disposed between the lifting guides 81 on the front side or the rear side of the lifting path 80. In addition, the other elevating member 821 is configured to be disposed between the elevating guides 81 on the rear side or the front side of the hoistway 80. As shown in FIGS. 8 and 9, the tray engagement / disengagement device 83 has a tray locking member 831 that can lock the lower surface edge of the tray 5 on each lifting member 821, and these tray locking members 831 horizontally. A linear motion guide 833 that guides movement in the direction and an engagement / disengagement drive unit 836 that drives the tray locking member 831 forward and backward are provided in pairs. In this case, each tray locking member 831 is a block-shaped member or a plate-shaped member capable of supporting the tray 5 and includes a locking protrusion 832 at the top end of the upper surface. The locking projection 832 is formed in a tapered shape with a gradually decreasing diameter upward so that it can engage with the locking recess 53 on the lower surface of the tray 5. Further, a slider 834 having a groove-shaped engagement surface at the bottom is attached to the lower surface of the tray locking member 831. Each linear guide 833 is made of a rail member having a cross-sectional shape corresponding to a dovetail groove, and is attached to the upper upper surface of each elevating member 821 so as to protrude in the opposing direction of each elevating member 821 via an attachment plate 835. On the linear motion guide 833, a tray locking member 831 is attached and disposed with the slider 834 engaged. The engagement / disengagement drive unit 836 employs a cylinder 836S, and an operation rod 836R that is driven back and forth is mounted on the upper lower surface (opposite side of the linear motion guide 833) of each lifting member 821 via a mounting plate 837. The actuating rod 836R and the tray support member 82 are operatively connected via a connecting member 838.

  As shown in FIG. 1, the lift drive device 84 of the lift 8 employs an upper drive system, and includes a drive motor 841 with a speed reducer installed above a predetermined lift guide 81 and upper and lower portions of each lift guide 81. And a plurality of sprockets 842 that are rotationally driven by a drive motor 841, and a lifting drive chain 843 that is wound around these upper and lower sprockets 842 and connected to the lifting member 821 of the tray support member 82. Prepare. The elevating drive device 84 is controlled by a control panel (not shown). As shown in FIG. 6, the tray support member 82 of the lift 8 is controlled by the control panel (not shown). 12) and the first retracted position of the lift 8 is set so that the tray support position of the lift 8 reaches the support position of the tray 5 arranged in the storage section 4 in the immediately upper layer (intermediate layer 12). In this retracted position, due to the shape and structure of the tray support member 82 of the lift 8, the common transport carriage 303 can pass through the lift 8 in an empty state in which no automobile is placed inside the tray support member 82, or the lift 8. An opening 820S that can enter and exit is configured. Although not shown, the tray support member 82 of the lift 8 is retracted between the lowermost level 13 and the level 12 immediately above, and the tray support position of the lift 8 is placed in the storage compartment 4 of the level 12 immediately above. A second retracted position of the lift 8 that reaches a predetermined height above the support position of the disposed tray 5 is set. At this retracted position, the tray support member is shaped according to the shape and structure of the tray support member 82 of the lift 8. Inside 82, an open part is formed that can pass through the lift 8 or enter and leave the lift in a state where the common transport carriage 303 is in the state of an actual vehicle on which an automobile is mounted.

  Next, FIG. 1 to FIG. 13 show the operation of this mechanical parking device 1, in particular, the transfer mode of warehousing for transferring an incoming car to each storage level, and the transfer mode for transferring the outgoing car from each storage level. The description will be given with reference selectively. In each transfer type, the operations of the lift 8, the transport carriage 3, the tray transfer device 7, and the tray lifting / lowering unit 6 are all performed based on control of a control panel (not shown).

  First, the case where the incoming car is transferred to the lowest floor 13 will be described. In addition, in this case, the operation | movement in which the motor vehicle is delivered in the highest hierarchy 11 is also illustrated. In FIG. 1, when an incoming car is placed on the tray 5 waiting in the loading / unloading unit 10 on the first floor above the ground, the lift 8 is driven, and the hoistway 80 of the lift is supported on the tray as shown in FIG. 10. The member 82 (with the tray locking member 831 of the tray engagement / disengagement device 83 protruding into the hoistway 80) is loaded with the tray 5 on which the automobile in the warehouse is placed, and is the lowest set below the hoistway 80. It is lowered toward the lowered position. In this case, the lowest lowering position of the lift 8 is set at the same level as the support position of the tray 5 in the storage section 4 of the intermediate hierarchy 12 (same as the first retracted position of the lift 8) when viewed from the support position of the tray 5. Has been. On the other hand, in cooperation with the lift 8, the lowest level 13 travels on the common transport path 203 toward the lift hoistway 80 in an empty state where the common transport carriage 303 does not carry the tray 5. Is done. Further, in the transport path 201 of the uppermost hierarchy 11, the transport truck 301 of the uppermost hierarchy 11 puts the tray 5 on which the car to be delivered is placed behind the common transport carriage 303 of the lowermost hierarchy 13, and the lift hoistway 80 It is driven toward.

  Subsequently, as shown in FIG. 11A, the tray support member 82 of the lift 8 is at the same level as the tray support position of the intermediate level 12 set as the lowest lowering position on the hoistway 80 (the first level of the lift 8). The lift 8 stops descending when it reaches the retreat position. At substantially the same time, the common transport carriage 303 in the lowermost layer 13 passes through the (inner side) opening 820S of the lifting member 821 on one side of the tray support member 82 of the lift 8 and enters the lift 8 (lift shaft 80). To enter. At this time, since the automobile on the tray 5 placed on the tray support member 82 is stored within the range of the height of the intermediate hierarchy 12, there is nothing protruding from the intermediate hierarchy 12 to the uppermost hierarchy 11. The transport carriage 301 in the uppermost layer 11 can enter the hoistway 80. Subsequently, as shown in FIG. 11 (b), the common transport carriage 303 in the lowest hierarchy 13 completely enters the lift 8 (the hoistway 80) and is stopped. Note that the transport carriage 301 in the uppermost layer 11 is entering the hoistway 80.

  Subsequently, as shown in FIG. 11 (c), the tray support unit 61 of the tray lifting / lowering device 6L is lifted by the drive of the tray lifting / lowering unit 6 mounted on the common transport carriage 303 in the lowermost layer 13, and this operation is performed. As the tray lifting / lowering device 6L is lifted at the same time (by the tray lifting / lowering assisting device 6A), the tray support 61 is lifted from the position where the automobile on the common transport carriage 303 is placed. When the tray support 61 (on the common transport carriage 303 side) reaches the tray support position of the stopped lift 8, the tray 5 is placed on the tray support section 61 (on the common transport carriage 303 side). On the other hand, as the tray support 61 is raised (on the common transport carriage 303 side), the latch protrusions of the tray support member 82 (on the lift 8 side) are moved from the respective locking recesses 53 on the lower surface of the tray 5. While detaching from 832 (see FIG. 9A), the paper is delivered to the tray support 61 (on the common transport carriage 303 side). The tray support 61 (on the common transport carriage 303 side) is stopped when the support position of the tray 5 reaches a predetermined height slightly above the tray support position of the storage compartment 4 in the intermediate level 12 ( At this stop position, the tray 5 and the tray engaging / disengaging device 83 of the lift 8 are completely separated.) During this time, the transport carriage 301 in the uppermost layer 11 completely enters the hoistway 80 without interfering with the operation of the lower layers 12 and 13.

  Subsequently, as shown in FIG. 12 (a), the tray locking member 831 of the tray engaging / disengaging device 83 of the lift 8 is retracted from the hoistway 80 by the engaging / disengaging drive unit 836, as shown in FIG. 12 (b). Further, when the tray engaging member 831 of the tray engaging / disengaging device 83 is retracted to the outside of the hoistway 80, the engaging / disengaging drive unit 836 is stopped, and the tray engaging member 831 is put on standby outside the hoistway 80. Accordingly, the tray engaging / disengaging device 83 of the lift 8 and the tray lifting / lowering unit 6 on the transport carriage 303 side do not interfere with each other, and the tray support 61 of the tray lifting / lowering device 6L (on the transport carriage 303 side) is placed on the hoistway 80. The descending path is opened. Note that the transport carriage 301 in the uppermost layer 11 is waiting on the hoistway 80.

  Subsequently, as shown in FIG. 13A, the tray support 61 of the tray lifting device 6L is lowered by driving the tray lifting / lowering unit 6 of the common transport carriage 303 in the lowest layer 13, and this operation is interlocked with this operation. Then, while the tray lifting / lowering device 6L is simultaneously lowered (by the tray lifting / lowering assisting device 6A), the tray support portion 61 is lowered from the stop position on the intermediate layer 12 to the position on which the automobile on the common transport carriage 303 is placed. The tray support 61 is stopped when it reaches the carriage frame 311 of the common transport carriage 303. Note that the transport carriage 301 in the uppermost layer 11 is waiting on the hoistway 80.

  Subsequently, as shown in FIG. 13B, the common transport carriage 303 in the lowermost layer 13 is driven, and the (inner side) opening 820S of the lifting member 821 on one side of the tray support member 82 of the lift 8 is moved. Pass through and exit the lift 8 (the hoistway 80). At this time, the common transport carriage 303 and the tray support member 82 of the lift 8 do not interfere with each other. At the same time, the lift 8 is driven and the tray locking member 831 of the tray engagement / disengagement device 83 is engaged. As shown in FIG. 9A, when the tray engaging member 831 of the tray engagement / disengagement device 83 enters the hoistway 80, the engagement / disengagement drive unit 836 enters the hoistway 80 by the dedrive unit 836. The tray support member 82 is raised with the tray locking member 831 protruding into the hoistway 80 while being stopped. The tray support member 82 reaches the uppermost layer 11, and the locking projection 832 of the tray support member 82 is placed on the transport carriage 301 on standby in the hoistway 80 of the uppermost layer 11. From below, the tray 5 on which this unloaded car is placed is delivered from the transport carriage 301 to the tray support member 82 of the lift 8 while being inserted into the respective locking recesses 53 on the lower surface of the tray 5 (see FIG. 9A). Is done. The tray support member 82 is raised as it is, the tray 5 is transferred to the loading / unloading unit 10, and the car is unloaded at the loading / unloading unit 10. Further, the common transport carriage 303 exiting from the lift 8 travels on the common transport path 203 of the lowest hierarchy 13 and is stopped at a position corresponding to the storage section 4 of the storage destination. Then, the tray transfer device 7 is driven, and the next tray transfer operation is started.

  (See FIGS. 1, 4 and 5) At this time, one transfer guide 52 of the tray 5 placed on the common conveyance carriage 303 is engaged with one engagement member 70 on the common conveyance carriage 303. The other transfer guide 52 is not engaged with the other engagement member 70. When this tray 5 is returned to the take-out source or the storage section 4 in the same row as the take-out source, the feed drive device 72 is activated immediately. When the drive motor 724 of the rotation drive unit 722 is activated, the rotation shaft 725 is rotated in the forward rotation direction, and this rotation is transmitted by the second sprocket 723 and the second endless chain 726 of the rotation drive unit 722 to be driven. The first sprocket 720 is normally driven. As the sprocket 720 is driven to rotate, the first endless chain 721 is similarly rotated in the forward direction, and one engagement member 70 attached to the endless chain 721 is engaged with one transfer guide 52 of the tray 5. In the combined state, the other engaging member 70 is not engaged with the other transfer guide 52 of the tray 5, and each linear guide 727 is slid (stored from the common transport carriage 303. When the tray 5 is fed to the section 4, it is guided linearly in the feeding direction of the tray 5, and moved straight on the storage section 4. As a result, the tray 5 on the common transport carriage 303 moves from the pair of traverse rails 611 (on the tray support portion 61) on the common transport carriage 303 to the pair of traverse rails 41 on the section 4 in each roller 50. Then, it is sent from the common transport cart 303 to the storage section 4. When the engagement member 70 engaged with the transfer guide 52 of the tray 5 is moved to the engagement / disengagement position on the storage section 4, this is detected by the sensor, and the operation of the feed drive device 72 is stopped. The joint member 70 is stopped at the engagement / disengagement position on the storage compartment 4. Then, the engagement / disengagement drive device 73 is operated, and the engagement member 70 is detached from the transfer guide 52 of the tray 5. In this way, the tray 5 is completely transferred from the common transport carriage 303 onto the storage section 4 in the same row as the extraction source or the extraction source.

  When the tray 5 is returned to the take-out source or the storage compartment 4 in a different row from the take-out source, one transfer guide 52 and one engagement member of the tray 5 placed on the common transport carriage 303 are used. The engagement state with the other transfer guide 52 and the disengagement state between the other engagement member 70 are switched. In this case, first, the engagement / disengagement drive device 73 is operated. When the power cylinder 735 is driven, the telescopic rod 736 is shortened or extended, and the base plate 730 is moved by a predetermined distance to the rear or front of the common transport carriage 303 by the guide of the linear motion guide 732. Is disengaged from the engagement / disengagement end on the front side or rear side of the transfer guide 52 from the engaged state with one transfer guide 52, and the other engagement member 70 is not engaged with the other transfer guide 52. From the state, the engagement / disengagement state between each engagement member 70 and each transfer guide 52 is switched by entering from the engagement / disengagement end on the rear side or the front side. Here, the operation of the engagement / disengagement drive device 73 is stopped, and the feed drive device 72 is operated. When the drive motor 724 of the rotation drive unit 722 is activated, the rotation shaft 725 is rotated in the reverse direction, and this rotation is transmitted by the second sprocket 723 and the second endless chain 726 of the rotation drive unit 722 to be transmitted on the drive side. The first sprocket 720 is driven in reverse. By the rotational drive of the sprocket 720, the first endless chain 721 is similarly rotated in the reverse direction, and one engagement member 70 attached to the endless chain 721 is engaged with one transfer guide 52 of the tray 5. In the state where the other engaging member 70 is engaged with the other transfer guide 52 of the tray 5, the linear guides 727 are slid (the storage compartment 4 opposite from the transport carriage 5). When the tray 5 is fed to the tray 5, it is guided linearly in the feeding direction of the tray 5 and moved straight on the storage compartment 4 on the opposite side. As a result, the tray 5 on the transport carriage 303 moves the rollers 50 from the pair of traverse rails 611 on the common transport carriage 303 to the pair of traverse rails 41 on the opposite storage compartment 4, and the common transport carriage 303. To the storage compartment 4 on the opposite side. When the engagement member 70 engaged with the transfer guide 52 of the tray 5 is moved to the engagement / disengagement position on the storage section 4, this is detected by the sensor, and the operation of the feed drive device 72 is stopped. The joint member 70 is stopped at the engagement / disengagement position on the storage compartment 4. The engagement / disengagement drive device 73 is actuated again, and the engaging member 70 is detached from the transfer guide 2 of the tray 5. In this way, the tray 5 is removed from the common transport carriage 303 and completely transferred onto the storage compartment 4 opposite to the original parking compartment 4.

  In the case where the empty tray 5 after leaving the car in the loading / unloading unit 10 is returned to the storage section 4 in the lowest hierarchy 13, the lift 8, the common transport carriage 303, and the tray transfer device 7 are operated in the same manner. The tray 5 is similarly transferred. Further, when the car is taken out from the storage section 4 of the lowest hierarchy 13 or when the empty tray 5 is transferred to the loading / unloading unit 10, the above operation is reversed. In particular, in the operation of unloading the car, the lift 8 is retracted to the second retracted position between the lowermost floor 13 and the intermediate floor 12, so that an opening is formed inside the tray support member 82, which is common. The transport cart 303 can pass through the lift 8 or enter and exit the lift 8 in the state of an actual vehicle with a car on it. Therefore, the common transport cart 303 on which the car that has been delivered is like the lift 8, and the common transport cart 303 It is possible to immediately shift to the delivery of the tray 5 (with a car) to and from the lift 8.

  Next, a case where the incoming car is transferred to the middle level 12 will be described. In this case (see FIG. 1), when an incoming car is placed on the tray 5 waiting in the storage / departure unit 10 on the first floor, the tray 5 is the same as the case where the incoming car is transferred to the lowest floor 13. Then, it is transferred by the lift 8 and transferred to the common transport cart 303 at the lowest level 13. When the common transport carriage 303 is withdrawn from the lift 8, it travels on the common transport path 203 in the lowest level 13 and stops at a position corresponding to the storage section 4 of the storage level in the intermediate level. Then, the tray lifting / lowering unit 6 is driven, and the next tray lifting / lowering operation is started.

  First, (see FIG. 6), the drive motor 624 of the tray lifting device 6L is driven to rotate, and the tray support 61 of the tray lifting device 6L is lifted. In conjunction with this lifting operation, the tray lifting device 6L (main body) is further moved. Is raised and lowered, and the tray 5 on which the incoming car is placed is raised from the position where the car is placed on the common transport carriage 303. (See FIG. 7) When the tray support 61 of the tray lifting / lowering device 6L is raised to the maximum tray lifting position, the tray lifting / lowering device 6L is raised to the maximum by the tray lifting / lowering auxiliary device 6A. ), The tray lifting / lowering device 6L further raises the support position of the tray 5, and the tray lifting / lowering device 6L has a maximum tray rising position in the storage compartment 4 in the upper hierarchy, that is, in the middle hierarchy 12. The tray 5 is raised incrementally to the support position of the arranged tray 5. When the tray 5 is raised to the support position of the tray 5 arranged in the storage section 4, the operation of the tray lifting / lowering unit 6 is stopped and the tray transfer operation is started. This tray transfer operation has already been described.

  In the transfer of the tray 5 to the intermediate level 12, the tray 5 is transferred by the lift 6 and transferred to the common transport carriage 303 in the lowest level 13, and then the tray 5 is supported by the tray lifting / lowering unit 6. The common transport carriage 303 is driven and moved to a position corresponding to the storage section 4 of the storage destination of the middle tier, and the tray 5 is moved by the tray transfer device 7 at a position corresponding to the storage section 4 of the storage destination. May be transferred from the common transport cart 303 to the storage section 4. This operation is preferable when the tray 5 on which the automobile is placed is stored in the storage section 4 adjacent to the lift 8.

  In addition, when the empty tray 5 after the vehicle exits is returned to the storage section 4 of the intermediate hierarchy 12 in the loading / unloading unit 10, the lift 8, the common transport cart 303, and the tray transfer device 7 are operated in the same manner. The tray 5 is similarly transferred. Further, when the car is taken out from the storage section 4 of the intermediate hierarchy 12, or when the empty tray 5 is transferred to the loading / unloading unit 10, the above operation is reversed. In particular, in the operation of unloading the car, the lift 8 is retracted to the second retracted position between the lowermost floor 13 and the intermediate floor 12, so that an opening is formed inside the tray support member 82, which is common. The transport cart 303 can pass through the lift 8 or enter and exit the lift 8 in the state of an actual vehicle with a car on it. Therefore, the common transport cart 303 on which the car that has been delivered is like the lift 8, and the common transport cart 303 It is possible to immediately shift to the delivery of the tray 5 (with a car) to and from the lift 8.

  Finally, a case where the incoming car is transported to the top level 11 will be described. In this case (see FIG. 1), when an incoming vehicle is placed on the tray 5 waiting in the storage / departure unit 10 on the first floor above the ground, the lift 8 is driven, and the tray support member 82 is moved over the lift shaft 80 of the lift. The tray 5 on which the car in the warehouse is placed is placed (with the tray locking member 831 of the tray engaging / disengaging device 83 protruding into the hoistway 80) and lowered to the uppermost layer 11. In the uppermost layer 11, the transport carriage 301 waits in advance on the lift hoistway 80. At the same time that the tray support member 82 of the lift 8 passes through both sides corresponding to the front and rear of the transport carriage 301 in the uppermost layer 11, the tray 5 on which the automobile on the tray support member 82 is placed is directly transferred to the transport carriage 301. It is put on the upper pair of traverse rails 611. The transport carriage 301 is withdrawn through the open portion of one lifting member 821 of the tray support member 82 of the lift 8 and travels on the transport path 201 in the uppermost layer 11. And it stops at the position corresponding to the storage section 4 of the storage destination, and the tray transfer operation is started by the tray transfer device 7. The tray transfer operation is as described above.

  In addition, when the empty tray 5 after leaving the car is returned to the storage section 4 of the highest hierarchy 11 in the loading / unloading unit 10, the lift 8, the common transport carriage 301, and the tray transfer device 7 are operated in the same manner. The tray 5 is similarly transferred. Further, when the car is taken out from the storage section 4 of the uppermost hierarchy 11 or when the empty tray 5 is transferred to the loading / unloading unit 10, the above operation is reversed. In particular, in the operation of unloading the automobile, the lift 8 is retracted between the uppermost tier 11 and the intermediate tier 12 so that the upper side of the tray support member 82 is opened, and the transport carriage 301 is in a state of an actual vehicle on which the automobile is placed. It is possible to pass through the lift 8 or enter and exit the lift 8, so that the transport carriage 301 on which the car that has been delivered is preferred is the lift 8, and the tray 5 (with the car) placed between the transport carriage 301 and the lift 8. Immediate transition to delivery.

  As described above, according to the above embodiment, the transport cart 303 in the lowest level 13 includes the tray lifting unit 6, and the delivery of the tray 5 between the lift 8 and the common transport cart 303 in the lowest level 13 is performed. Since it is performed at a predetermined height set between the lowest floor 13 and the intermediate floor 12 above it, a lift pit can be made unnecessary from the floor of the installation space. At the same time, the tray transporting unit 303 and the tray transfer device 7 are provided in the common transport carriage 303 of the lowermost hierarchy 13, while the transport carriage is eliminated from the intermediate hierarchy 12 above the lowermost hierarchy 13 and is replaced with the transport path. Thus, an elevating space 202 for the tray 5 communicating with the common transport path 203 is provided, and the tray 5 is transported, lifted and moved between the common transport cart 303 and the storage compartments 4 of the lowest hierarchy 13 and the intermediate hierarchy 12. Since the transfer of the trays 5 of the lowermost tier 13 and the intermediate tier 12 is centralized in the common carrier trolley 303, in this case, the intermediate tier 12, the transport trolley for one tier and the transport path are The floor height of the middle floor 12 can be reduced and the overall height of the parking device 1 can be compressed as a result.

  Further, the tray lifting / lowering unit 6 is configured within a predetermined height range lower than the height set in the common transport path 203 in the common transport cart 303, while the tray support member 82 of the lift 8 is configured as a whole. The height is configured to be smaller than the height set in the transport path 201 or 203 of the first storage level 11 or 12 or 13 or the lifting space 202 of the tray, and in particular, the lifting member 821 of the tray support member 82 has each storage level 11, It has a substantially portal shape that can open both the transport paths 201 and 203 of the upper and lower storage tiers 11, 12, 12, and 13, or the raising / lowering space 202 of the tray, while waiting between 12 or 12 and 13. Therefore, the lift 8 is between the lowermost layer 13 and the intermediate layer 12 immediately above it, and the tray support position of the lift 8 is the support position of the tray 5 arranged in the storage section 4 of the intermediate layer 12 immediately above. The common transport carriage 303 can pass through the lift 8 or enter and leave the lift in an empty state where no automobile can be placed through the inside of the tray support member 82 of the lift 8. The lift 8 is located between the lowest level 13 and the intermediate level 12 immediately above it, and the tray support position of the lift 8 is a predetermined level above the support position of the tray 5 arranged in the storage section 4 of the intermediate level 12 immediately above. The common transport carriage 303 passes through the lift 8 or enters and exits the lift 8 in the state of an actual vehicle on which the automobile is placed through the inside of the tray support member 82 of the lift 8 by being retracted to a position reaching the height of the lift 8. The empty tray 5 (the tray 5 on which the car is not placed) or the actual tray 5 (the tray 5 on which the car is placed) between the common transport cart 303 and the lift 8 It can be carried out smoothly.

  In the parking apparatus 1, the common transport carriage 303, the tray lifting / lowering unit 6 on the transport carriage 303, and the tray support member 82 of the lift 8, particularly in the height direction of the storage layers 11, 12, 13, are provided. Since it is configured to be small in size, the vehicle of the automobile to be accommodated for each storage hierarchy 11, 12, 13 at the height of the parking space set on each storage section 4 of each storage hierarchy 11, 12, 13 A dimension as close as possible to the height can be set, and by setting in this way, the floor height and the overall height of the parking facility can be compressed as much as possible. Furthermore, since the tray transfer device 7 is mounted on the common transport carriage 303 so that it can be moved up and down by the tray lifting / lowering unit 6, the tray transfer device 7 can be shared between the lowest layer 13 and the middle layer 12, The intermediate layer 12 can be further simplified, and an increase factor of the floor height can be removed.

  In the above embodiment, the parking facility having an underground type and a storage hierarchy of all three levels is exemplified, and two levels of the lowest level and the middle level are selected from all the three levels, and are common to the lowest level. Equipped with a transport carriage, and on this transport carriage, the tray lifting unit is limited and mounted within the height range of the lowest hierarchy, while the transport carriage is eliminated from the upper middle hierarchy, and instead of the transport path, it is common The tray lifting / lowering space is formed by the tray lifting / lowering unit. However, the same structure can be adopted by selecting the middle and uppermost two levels. In this case, although it is necessary to provide a lift pit as in the prior art, it is effective when it is necessary to compress and adjust the height of the entire parking facility due to the height of the installation space. Moreover, in the said embodiment, although the storage hierarchy of all the 3 levels is illustrated, if it is a parking facility which has a storage hierarchy of 2 levels or more, it can apply similarly and obtain the same effect. Can do. In this case, if there are four or more storage tiers, two or more sets of two or more adjacent storage tiers can be set. Therefore, the same configuration is applied to each of two or more sets of upper and lower two storage tiers. It is possible to provide the same operational effects. Moreover, even when it has four or more storage hierarchies, it is possible to select a part of two or three hierarchies, have the same configuration, and achieve the same effects. In the case of large-scale parking facilities with a large number of storage tiers, the floor height can be reduced by eliminating the transport cart and arbitrarily increasing the storage tiers that change the transport path to the lifting space of the tray. As a result, the overall height of the parking facility can be greatly shortened, and the parking facility can be downsized and the installation space can be saved.

  In the above-described embodiment, the tray lifting / lowering assisting means is configured as a lifting / lowering mechanism that uses the drive motor 624 of the tray lifting / lowering device 6L and moves the tray lifting / lowering device 6L in conjunction with the tray lifting / lowering device 6L. A jack, a cylinder, etc. are employ | adopted for this tray raising / lowering assistance means, and the tray raising / lowering apparatus 6L may be comprised as a raising / lowering drive apparatus independently driven up / down irrespective of the movement of tray raising / lowering apparatus 6L. Further, this tray lifting / lowering assisting means uses the tray supporting portion of the tray lifting / lowering device 6L, and this tray supporting portion is formed by four substantially L-shaped tray supporting members, or four substantially L-shaped supporting members. The tray raising maximum position of the tray lifting / lowering device 6L may be extended by configuring the member and a frame-like tray supporting frame supported by these supporting members.

  Further, in the above embodiment, the new tray transfer device 7 is mounted on each of the transport carriages 301 and 303. However, a method of turning the arm provided with an engaging member such as a roller at the tip, It can be replaced with a conventional tray transfer device such as a method.

  Furthermore, in the said embodiment, although the raising / lowering member 821 of the tray support member 82 is formed in the substantially portal shape, the shape is made into a substantially inverted U shape, a substantially inverted portal shape, a substantially U shape, or a substantially H shape. It is also possible to divide the elevating member 821 at an intermediate portion, or to connect a plurality of independent tray supporting members to different elevating members. Can be changed. Regardless of the shape of the tray support member 82, the same effect as that of the lift 8 can be obtained by providing the opening portions of the transport carriages 301 and 303 above, below, or both above the tray support member. Can do.
