When 103 is completely moved on the divided rail portion 201c on the transport path 7, it is stopped.

During this time, the lift 6 stands by at the bottom of the upper storage tier 3U. The tray support member 6L of the lift 6 is formed in a gate shape toward the transport path 2 of the lower storage layer 3D, and its tray receiving portion 623 is arranged between the vertically adjacent storage layers 3U, 3D. The pass-through opening portion 60 therebelow is disposed in the lower storage layer 3D, and the transport vehicle 1 is provided on the transport path 2 of the lower storage layer 3D, particularly on the hoistway 7.
An open space is secured with a height and width that allows the vehicle to be loaded and moved. Therefore, the carrier truck 1 has the carrier path 2
It can pass through the hoistway 7 and can travel back and forth along the entire transport path 2, and the preparation for the entry or exit of the vehicle on the lower storage level 3D is performed as necessary. That is, in the lower storage level 3D, the transport carriage 1 moves on the pair of rails 201 of the transport path 2 to the front of the storage compartment 3 of the storage destination of the automobile or the storage compartment 3 of the storage destination of the automobile. At this time, the carriage 1 is guided on the pair of rails 201 by the engagement of the guide roller 104 of the carriage 1 and the rail 201 on one side,
The carrier 1 travels reliably and at high speed on the pair of rails 201. Subsequently, the tray transfer device 11 is operated in front of the storage compartment 3 of the vehicle at the storage destination or the storage destination,
The tray 4 is pulled out onto the transport carriage 1 by the turning of the turning arm 81. When the tray 4 is completely delivered onto the carrier 1, the tray 4 is fixed by a tray lock device (not shown). Then, with the engagement member 82 and the guide member 75 still engaged, the transport carriage 1 travels on the transport path 2 toward the hoistway 7, and is located at a position adjacent to the hoistway 7 (a passage portion of the pair of rails 201). It stops and waits before 202.

At the upper storage level 3U, the carrier truck 1 moves up and down the hoistway 7.
When stopped, the lift 6 rises on the hoistway 7 from the lower part of the storage hierarchy 3U. That is, the pair of lifting members 6
21 moves up and down the hoistway 7, and the tray receiving portions 6 are respectively provided.
23 is brought into contact with the lower surface of the tray 4 on the carriage 1, and at the same time, the locking projections 624 and the engaging recesses 41 of both are engaged, and the tray 4 is pulled upward from the carriage 1 while stably and reliably supporting the tray 4. . At this time, the tray 4 on the carrier truck 1
Even if there is a misalignment between the locking recess 41 of the lock 6 and the locking projection 624 of the tray support member 6L of the lift 6, the locking recess 4
The engaging projection 624 of the tray supporting member 6L slightly engages with the engaging hole 410 of the engaging member 411 that constitutes the first member 1, so that the engaging member 411 is moved in the horizontal direction with respect to the height adjusting member 43. However, the locking recess 41 and the locking projection 6
24 is positively engaged. By this rise of the tray 4, the engagement member 82 of the tray transfer device 11 is disengaged from the guide member 75 on the lower surface of the tray 4, and the engagement is released. Then, the lift 6 is lifted on the hoistway 7 to the entry / exit floor of the vehicle, and the entry / exit of the vehicle is carried out.

When the unloading of this vehicle is completed, the lift 6 on which the empty tray 4 is placed is moved down the hoistway 7 to the original storage level 3U, and on the hoistway 7 of the storage level 3U, the carrier truck 1 is placed.
To the position where the tray 6 is stopped, the lift 6 on which the tray 4 is placed is lowered from above the transport carriage 1 on the hoistway 7. That is, the pair of elevating members 621 descends the hoistway 7 and is supported and locked on each tray receiving portion 623.
Is lowered onto the carrier 1 and the engaging member 82 is inserted into the guide member 75 on the lower surface of the tray 4 from below,
Both are engaged. At the same time, the elevating members 621 pass on both sides of the transport carriage 1, the tray receiving portions 623 separate from the tray 4, and the lift 6 is lowered below the transport carriage 1.

Regarding the mutual operation relationship between the lift 6 on which the tray 4 is placed and the carriage 1, in the case of the lower loading method, the following points are slightly different. That is, when the exit of the vehicle is completed, the lift 6 on which the empty tray 4 is placed is lifted up the hoistway 7 to the original storage level 3U and stopped at a predetermined position slightly higher than the level of the storage level 3U. Then
The carrier 1 is moved on the hoistway 7 after passing through the pair of rails 201 and the passing portion 202. Transport truck 1 is hoistway 7
When stopped above, the lift 6 is lowered from above the transport carriage 1 on the hoistway 7. The following operation is the same as that of the above-mentioned upper boarding method.

Further, in the intermediate loading system, the tray transport operation between the loading level and the storage hierarchy below it is the same as the upper loading system, and the loading level and the storage above it. The transfer operation of the tray with the hierarchy has the same operation relationship as the lower loading method.

When the tray 4 is thus transferred from the lift 6 to the transport carriage 1, the transport carriage 1 moves on the pair of rails 201 of the transport path 2 to the front of the original storage compartment 3. In front of the storage compartment 3, the turning arm 81 is swung in the direction of the storage compartment 3 by the operation of the tray transfer device 11, and the tray 4 is sent out from the transport carriage 1 to the storage compartment 3 to form a pair of traverses. It is placed on the rail 301.

On the other hand, when the empty tray 4 is transferred from the lift 6 to the transport vehicle 1 of the upper storage floor 3U, the lift 6 is lifted.
Is lowered to the bottom of the lower storage tier 3D and stopped. By the passage opening portion 60 of the tray support member 6L of the lift 6, the transport path 2 of the lower storage level (the storage level lower than the lower storage level 3D), particularly the hoistway 7, is similarly An open space in which a height and a width are secured so that the carrier vehicle 1 can move a vehicle is maintained, and the carrier vehicle 1 can pass through the hoistway 7 of the carrier path 2.
The entire vehicle can be reciprocated, and preparations for entering or leaving the vehicle are made as necessary. In the lower storage level 3D, preparations for entering or exiting the vehicle have already been completed, and the empty tray 4
Alternatively, when the carrier truck 1 on which the actual tray (car tray) 4 is placed is waiting at the position adjacent to the hoistway 7 and the lift 6 is stopped at the lower part of the storage hierarchy 3D, the carrier is immediately conveyed. The dolly 1 enters the hoistway 7. At this time, even if the tray support member 6L is waiting in the lower part of the lower storage layer 3D, the transport cart 1 has an external protrusion such as the current collector 108 passing over the upper step portion 622 of the tray support member 6L. As a result, the stepped recesses 10 on both sides of the lower surface
When 6 passes over each locking protrusion 624 of the tray supporting member 6L, the tray 6 is moved without interfering with the tray supporting member 6L. When the carrier 1 is stopped on the hoistway 7,
As described above, the lift 6 is lifted on the hoistway 7 from the lower part of the storage layer 3D, and the tray 4 is transferred from the carrier 1 to the tray support member 6L of the lift 6. Lift 6
Is raised to the entry / exit floor of the vehicle on the hoistway 7, and the entry / exit of the vehicle is performed on the entry / exit floor of the vehicle.

In the above operation example, the empty tray 4 or the actual tray 4 is transferred from the storage compartment 3 adjacent to the hoistway 7 to the transport carriage 1 in the lower storage floor 3D during the shipping operation at the upper storage floor 3U. When loaded, the carrier 1 is once moved from above the hoistway 7 to a position adjacent to the hoistway 7 through the passage opening 60 of the tray support member 6L of the lift 6 and stands by there. The subsequent operation is the same as the above operation example. Further, in the above operation example, the case where the vehicle is unloaded in the upper storage tier 3U is illustrated, but even when the vehicle is loaded in the upper storage tier 3U, the empty tray and the actual tray are simply reversed. The operation procedure is the same.

As described above, according to the above-described embodiment, the tray supporting member 6L of the lift 6 is formed in a substantially gate-like shape in the direction facing the carrier vehicle 1, the tray receiving portion 623 is provided on the upper portion, and the tray receiving portion 623 is opened below to open. In the state where the portion 60 is formed and the tray support member 6L is on standby between the upper and lower adjacent storage floors 3F, the transport carriage 1 on the transport path 2 of the lower storage floor 3D places the automobile on the hoistway 7. Since it is possible to pass through, while the car storage or exit operation is in the upper storage level 3U,
At the same time, in the lower storage level 3D, the carrier vehicle 1 can pass through the hoistway 7 of the carrier path 2 and travel back and forth on the entire carrier path 2, and the preliminary operation for loading or unloading the vehicle can be performed at the same time. It is possible to smoothly execute the loading / unloading operation of the vehicle as the entire parking device.

Further, since the step portion 622 which is lower than the intermediate portion is formed on at least one side of the upper portion of the tray supporting member 6L, the tray supporting member 6L stands by between the upper and lower adjacent storage layers 3F. However, external projections such as the current collector 108 of the transport vehicle 1 of the upper storage layer 3U do not interfere with the tray support member 6L, and the transport vehicle 1 reliably moves on the tray support member 6L at the upper storage layer 3U. Can pass through.

Since the tray supporting member 6L is provided with a locking projection 624 projecting upward and the lower surface of the tray 4 is provided with a locking recess 41 which can be engaged with the locking projection 624, the tray 4 is provided. 4 can be reliably supported without dropping on the lift 6. In addition, the locking recess 41 of the tray
Is a height adjusting member 43 for adjusting the height on the lower surface of the tray 4.
Is fixed to the height adjusting member 43, and an engaging member 411 having an engaging hole 410 with which the engaging protrusion 624 can be engaged is formed so as to be movable in the horizontal direction by a predetermined amount. The height adjusting means 43 can cope with a case where the tray support level of the tray support member 6L of the lift 6 is insufficient in order to raise the tray 4 to a predetermined height on the entry / exit floor of the automobile. The tray 4 is moved from the carrier 1 to the lift 6 by the engagement position adjusting means 44.
When delivering, the locking recess 41 of the tray 4 on the carrier 1 and the locking projection 6 of the tray support member 6L of the lift 6
Even if the core is misaligned with the tray 24, the locking recess 41 of the tray 4 and the locking projection 624 of the tray support member 6L are securely engaged with each other to securely support the tray 4 on the lift 6. Therefore, the landing of the tray 4 on the entry / exit floor (stop position)
The accuracy can be significantly improved.

Further, since the stepped recesses 106 are provided on both sides of the lower surface of the carrier truck 1 of each storage floor 3F, the carrier truck 1 is provided.
Does not interfere with the locking projections 624 of the tray supporting member 6L waiting in each storage layer 3F, and the tray supporting member 6L
You can definitely pass over. In addition, the carriage 1
Is a plurality of wheels 10 that can roll on a pair of rails 201.
3 and a plurality of guide rollers 104 engageable with both side edges of one rail 201 on one side, each wheel 103 of the carriage 1 is guided to travel on the pair of rails 201, and the carriage 1 Can reliably travel on the pair of rails 201 and can travel at high speed.
Further, the carrier vehicle 1 is configured as a self-propelled type by trolley power supply, and its control panel 107 is arranged at least below the support level of the tray 4 and is formed in a thin shape as a whole. The height direction can be compressed, and the height direction of the entire parking device can be compressed.

In the present embodiment, the hoistway 7 of the lift 6 is illustrated as being set at the intermediate portion on the transport path 2, but it may be set at the end thereof.
Even in this case, the same operational effects as those of the above-described embodiment can be obtained. Further, the present embodiment has the same basic configuration as the conventional plane reciprocating parking device except for the structure of the passage opening portion 60 of the tray support member 6L, and thus is similar to the conventional plane reciprocating parking device. It goes without saying that it also has excellent effects.

Further, in the above-mentioned embodiment, the tray support member 6L is provided with the through-opening portion 60, and the tray support member 6L is in a standby state between the vertically adjacent storage floors 3F and the storage floors 3F. The carriage 1 of the carriage 2 is mounted with a car so that the carriage can pass over the hoistway 7. Instead, the entrance side of the carriage 1 to the hoistway 7 is one side, and the tray support member 6L is provided. May be configured such that only one side thereof is formed into a substantially gate shape, the tray receiving portion 621 is provided on the upper portion, and the advancing / retreating opening portion 60 is formed below the tray receiving portion 621. When it is set to the end portion of, the entrance side of the carriage 1 to the hoistway 7 becomes one side, and therefore it can be applied to such a case.

Further, in the above embodiment, the tray support member 6L is formed integrally with each pair of substantially gate-shaped (substantially inverted U-shaped) lifting members 621, but the shape thereof is substantially U.
It can be changed to a letter H shape or an approximately H shape, and these lifting members 6
21 may be divided at an intermediate portion, or a plurality of independent tray supporting members may be connected to separate elevating members, and the overall shapes of the tray supporting members and the elevating members may be arbitrarily changed. Of course. Regardless of the shape of the tray support member or the elevating / lowering member, by providing the pass-through opening portion above or below the tray support member or both of them, the same effect as the above-described embodiment can be obtained. be able to.
