A first rail portion provided in each of a plurality of storage portions for storing a vehicle, a first rail portion having a pair of rails, and a traveling cart traveling on the first rail portion, and are substantially U-shaped in plan view. A traveling vehicle having a plurality of projecting pieces protruding inward in the substantially U-shape, and a pallet for mounting a vehicle removably on the traveling vehicle. A pallet having a projecting piece at a predetermined portion of an outer periphery, and a lift capable of moving up and down with the pallet mounted thereon, wherein the projecting member has a length greater than a width between a pair of rails in the first rail. And is supported outside the pair of rails The lift and the lift space of the lift or the second rail provided in the vicinity thereof form the same traveling path as the first rail, and the first rail is passed by the protruding member of the lift. And a second rail portion having a gap between the second rail portion and the second rail portion.

In the three-dimensional parking device of the first configuration, the pallet is removably mounted on the traveling vehicle, so that the traveling vehicle is carried out from the first rail portion to the second rail portion. . At this time, after the lift is raised to the position of the second rail portion, the pallet is lifted by the lift. Then, the traveling vehicle slightly returns to the first rail portion side. In this case, since the pallet is supported on the traveling vehicle via the protruding piece, the pallet can be lowered only by slightly returning the traveling vehicle to the first rail portion side. Then, the lift descends with the pallet placed thereon, and reaches the vehicle standby position. Then, the vehicle is moved on the pallet, and in a state where the vehicle is placed on the pallet, the lift is raised to reach the position of the second rail portion, and stops at the position where the pallet is lifted. Then, the traveling cart returns to its original position, and when the lift is slightly lowered,
The pallet is placed on a traveling cart. Then, the traveling cart is carried into the first rail portion and the vehicle is stored.

[0007] The same operation as described above is performed when a vehicle that has been stored and stored is taken out of the vehicle. That is, the traveling vehicle is carried out from the first rail portion to the second rail portion, and the pallet on which the vehicle is mounted is lifted by the lift. Then, the traveling vehicle slightly returns to the first rail portion side, and the lift descends with the pallet placed thereon, and then moves the vehicle from the pallet at a predetermined position. Thereafter, the lift rises to reach the position of the second rail portion, and stops at the position where the pallet is lifted. Then, the traveling cart returns to its original position, and when the lift is slightly lowered, the pallet is placed on the traveling cart. Then, the traveling cart is carried into the first rail section.

Accordingly, the traveling vehicle has a substantially U-shape,
In addition, since the pallet is supported on the traveling trolley via the protruding piece, the pallet can be quickly lowered only by slightly retracting the traveling trolley, and the pallet can be standby at the slightly retracted position. Therefore, the pallet can be quickly placed on the traveling carriage even after the pallet returns. In addition, since a gap is provided between the first rail portion and the second rail portion, and the lift is supported outside the pair of rails, it is possible to eliminate trouble in movement of the traveling vehicle and elevation of the lift. .

Second, in the first configuration, the first rail portion is provided on both sides of the second rail portion. Therefore, the storage space can be provided as much as possible by effectively using the parking space.

[0010] Thirdly, in the first or second configuration, the multi-story parking device causes the traveling bogie to be carried out from the storage position in the first rail portion to the second rail portion, and to be moved to the second rail portion. An unloading step of stopping at a regular position above, a lifting step of raising a lift to a pallet lifting position and lifting a pallet placed on the traveling carriage while the traveling carriage is at the regular position; Evacuation step of moving the pallet from the regular position to the first rail portion side until the pallet is no longer supported by the traveling trolley, descending step of lowering the lift with the pallet mounted on the lift, Lifting the lift with the pallet placed on the pallet, stopping the pallet at the pallet lifting position, returning the retracted traveling vehicle to the normal position, A supporting step of supporting the lowering is caused by the pallet on the traveling carriage, characterized by having a a loading step for loading the traveling vehicles to the storage position in the first rail section.

Therefore, when the vehicle is to be stored, it is sufficient to place the vehicle on the pallet lowered in the lowering step, and when the vehicle is to be discharged, the pallet with the vehicle mounted thereon is mounted. When the traveling cart is carried out in the carrying out step and descends in the descending step, the vehicle may be moved from the pallet.

It is assumed that 31 has been designated.

In this operation example, it is assumed that the lift 162 is located on the first floor in the initial state. If the driver wants to park on the first floor of the rear row entry / exit area G, he / she may pass through the lift 162 as it is.

If the loading / unloading unit U31 is designated, the lift 162 moves the pallet 12 as shown in FIG.
0 to be placed on this lift 162. At the same time, the traveling cart 110 of the entry / exit unit U31
The traveling starts from the state where it is stored on the unit rails 100a and 100b, and is conveyed to the central rails 150a and 150b. That is, movement in the unloading direction is started. This is the unloading step. The position where the traveling vehicle 110 is stored on the unit rails 100a and 100b is referred to as a "storage position".

Then, as shown in FIG.
0 reaches a predetermined position on the center rails 150a and 150b (this position is referred to as a "normal position on the center rail").
In addition, the pallet 120 shown by the one-dot chain line in FIG. And
With the pallet 120 standing by at the regular position on the central rail, the lift 162 approaches and as shown in FIG.
Lift 162 lifts pallet 120. This is the lifting step. At this time, since the lift 162 has a certain thickness, the projecting member 16 of the lift 162
The pallet 120 can be lifted without the contact points 8 and 169 coming into contact with the traveling carriage 110. This pallet 1
The position of the lift 162 that can lift the lift 20 is referred to as a “pallet lift position”. The lift 162
Is slightly lower than the pallet lifting position (this position is referred to as a "lift standby position") so as not to hinder the unloading of the traveling carriage 110 when the pallet arrives first.
It is assumed that it has stopped.

When the lifting of the pallet 120 is completed,
As shown in FIG. 11, the traveling vehicle 110 is slightly moved in the carrying-in direction opposite to the carrying-out direction and retracted. That is, the pallet 120 is moved to such an extent that it does not hinder the lowering of the pallet 120. This is the evacuation step. The traveling vehicle 1
10 has a substantially U-shape as described above, and since the transverse direction member is not provided at the end of the traveling vehicle 110 on the unloading direction side, the traveling vehicle 110 is moved without hitting the lift 162. be able to. In addition, the pallet 1
Reference numeral 20 denotes a projecting piece 126a to 126f on the traveling carriage 110.
, The pallet 120 can be lowered by slightly moving the traveling carriage 110. The traveling carriage 110 waits for the pallet 120 to come again at a position slightly moved from the predetermined position (regular position on the center rail). This standby position is referred to as a “small distance movement standby position”.

Then, the lift 162 on which the pallet 120 is placed is lowered (down step) to reach the ground surface as shown in FIG. When the pallet 120 reaches the ground surface, the driver moves the vehicle K forward and places it on the pallet 120 as shown in FIG. Then, the driver gets off the vehicle K and performs a predetermined operation on the operation panel unit 210.

Then, the lift 162 on which the vehicle K is placed on the pallet 120 rises as shown in FIG. This is the above ascent stroke. Then, the lift 162 is
As shown in FIG. 5, the pallet 120 reaches the position of the traveling carriage 110 waiting at the small-distance movement standby position, and the protruding pieces 126a to 126f of the pallet 120 are slightly higher than the protruding pieces 116a to 116f of the traveling trolley 110. Position. That is, the pallet is stopped at the pallet lifting position. Then, the traveling vehicle 110 moves in the unloading direction from the short distance movement standby position and returns to the regular position on the center rail. This is the return step. And lift 16
The pallet 120 can be placed on the traveling carriage 110 by slightly lowering the pallet 2. The step of supporting the pallet 120 on the traveling carriage 110 in this manner is the above-described supporting step.

Then, as shown in FIG. 16, the traveling carriage 110 is transported in the carrying-in direction and stored in the storage position. This is the loading step. On the other hand, the lift 162
Returns to the first floor position.

It should be noted that, contrary to the above, when the vehicle K stored in the entry / exit unit is ejected, the same operation as described above is performed. That is, the traveling cart 110 of the loading / unloading unit is carried out to the regular position on the center rail, and the lift 162 is moved up to that position.
Lift 0. Then, after moving the traveling carriage 110 to the small-distance movement standby position, the pallet 1 on which the vehicle K is placed is placed.
The lift 162 on which the device 20 is placed is lowered. The traveling carriage 110 is then mounted on the unit rails 100a, 10a.
What is necessary is just to return to the storage position on 0b.

As described above, according to the multi-story parking apparatus A of the present embodiment, the lift 162 can be lifted up and the traveling carriage 110 can be carried out independently. For example, the lift 162 waits at the lift standby position. Since the traveling vehicle 120 is not unloaded after the operation, the time for loading and unloading can be reduced. In addition, as described above, the traveling vehicle 1
10 has a substantially U-shape, and the pallet 120 is supported on the traveling carriage 110 via the projecting pieces 116a to 116f and the projecting pieces 126a to 126f.
The pallet can be quickly lowered by only slightly retracting the traveling trolley.
While waiting for the return of the pallet 120, the pallet 120 need not be stored in the storage position as long as the pallet 120 is in the storage position. 110. As described above, it is possible to shorten the time for entering and leaving the warehouse. In addition, according to the multi-story parking device A of the present embodiment, if there is a space approximately equal to the width of one vehicle, it can be installed, so that a small space can be effectively utilized.

In the above description, the direction in which the vehicle is carried in and out of the loading / unloading unit is described as being the longitudinal direction of the vehicle. However, the present invention is not limited to this.
A structure for carrying out / in in the short direction of the vehicle may be adopted.
In this case, the longitudinal member of the traveling vehicle 110 is formed shorter than the short member, and the vehicle is also shown in FIG.
In this case, the object moves from the Y2 direction.

In the above description, the traveling vehicle 1
Although it has been described that the traveling of the vehicle 10 is performed by driving the chains 136a and 136b, other methods, for example, a method of driving the wheels themselves provided on the traveling vehicle 110 may be employed. Further, in the above description, the lift 162 is described as being lifted and lowered by the wires 170 and 172, but may be lifted and lowered by other methods. For example, the lift 162 may be supported by four pillars penetrating the projecting members 168 and 169 instead of wires, and may be moved up and down along the pillars.
