Description of the Related Art Conventionally, as one type of mechanical parking apparatus, as disclosed in, for example, Japanese Utility Model Laid-Open No. 6-63752, both sides of a traveling path along which a traveling carriage travels along the traveling path. Adjacent space rows adjacent to each other and a rear space row adjacent to the adjacent space row on the side opposite to the moving path, are provided in parallel with each other, and each space row includes a vehicle-mounted pallet. It is known that a plurality of accommodation spaces are arranged in series along a moving path. Then, as the vehicle's unloading operation in this parking device, a pallet carrying a vehicle that is requested to leave is transferred to a loading space on the traveling dolly, and the traveling dolly is moved to a position corresponding to the exit of the trolley along the moving path. It is moved to, and the vehicle is taken out from this exit.

Further, in particular, in the above-mentioned publication, the traveling carriage is provided with two mounting spaces so that the vehicle in the rear space row can be easily carried out. That is, when transferring the pallets in the rear space row to the traveling carriage, first, one of the storage spaces in the adjacent space row adjacent to the storage space in which the requested pallet in which the vehicle with the delivery request is mounted is stored is The traveling carriage is moved so that the mounting space is located, and the pallets in the adjacent space rows are transferred to the one mounting space. After that, the traveling carriage is moved, the other loading space is positioned corresponding to the accommodation space of the required pallet, and the required pallet is transferred to the other loading space. In this state, the traveling carriage is moved to a position corresponding to the exit and the vehicle is unloaded.

[0004]

By the way, in the parking apparatus for performing the leaving operation as described above, when the vehicle accommodated in the accommodation spaces located at both ends in the extension direction of the rear side space row is to be ejected, In the process of transferring the pallets in the space row to the traveling carriage, there is a problem that part of the traveling carriage protrudes from the end of the space row group. That is, as an operation of leaving the vehicle at the end of the back space row, as shown in FIGS. 17 to 19 (for convenience, the upper side is referred to as the front side and the lower side is referred to as the rear side), as shown in FIGS. As shown in FIG. 17, the traveling carriage c is moved so that the rear mounting space e is located corresponding to the accommodation spaces a and b at the front end, and as shown in FIG.
The pallet p1 in the accommodation space a at the front end of the adjacent space row A is transferred to the rear mounting space e. At the same time, the pallet p2 of the accommodation space b at the front end of the back space row B is moved to the accommodation space a of the adjacent space row A. During this operation, as shown in FIGS. 17 and 18, the front loading space d of the traveling carriage c is in the space row A,
It projects further forward than the front edge of B (dimension t in FIG. 18). Then, as shown in FIG. 19, the traveling carriage c is moved backward to position the front side mounting space d corresponding to the accommodation spaces a and b at the front end, and the front side mounting space d is moved.
The requested pallet p2 is transferred to. In this state, the traveling carriage c is moved to a position corresponding to the exit and the vehicle is exited. The same operation is performed when the vehicle stored in the storage space at the end of the rear space row is unloaded, and in this case, the rear loading space e of the traveling vehicle c is located in the space row. It projects rearward from the rear edge of A and B. Further, the pallet p1 of the accommodation space a of the adjacent space row A is transferred to the front placement space d, and then the pallet p of the accommodation space b of the back space row B is placed.
2 is transferred to the rear mounting space e, the pallet p2 in the rear space row B is moved to the traveling carriage c.
At the time of the transfer, the portion of the front mounting space d of the traveling carriage c projects forward from the front end edges of the space rows A and B.

As described above, in the process of transferring the pallets p2 located at both ends of the rear space row B to the traveling carriage c, a part of the traveling carriage c projects from the end portions of the space rows A and B. Therefore, it is necessary to secure a space for allowing the protrusion at both ends of the moving path in advance, and there is a problem that the moving path becomes long and a large installation space is required for the entire device. It was

Since it also has a pallet supporting function when moving, the number of parts can be reduced.

Since the vehicle is unloaded by such a unloading operation, when the pallet in the accommodation space at the front end of the adjacent space row is placed on the traveling carriage as in the conventional case, the first placement space is the space row. It does not protrude further than the front edge. Therefore, it is not necessary to secure a space for allowing the protrusion at the end of the moving path in advance, and accordingly, the moving path can be made shorter than the conventional one and the installation space of the entire apparatus can be reduced. Can be achieved.

Further, when the pallet of the accommodation space at the rear end of the back space row is placed on the traveling carriage, the same operation is performed, so that the second loading space is located farther than the rear edge of the space row. It does not project backwards.

When one of the plurality of accommodation spaces is set as an empty space and a vehicle in the rear space row is to be unloaded, the pallet in the adjacent space row adjacent thereto is temporarily moved to the empty space and then the rear space row is moved to the rear space. It is not necessary to place the pallet in the side space row on the traveling carriage and move it to the exit port.

As described above, according to this embodiment, it is possible to prevent the mounting space of the traveling carriage from protruding from the end portion of the space row during the leaving operation of the vehicle, and It is possible to achieve both a quick leaving operation and a highly practical mechanical parking facility.

In addition, the pallet P is placed in each of the mounting spaces 28,
When moving between 29, the outer rollers 33, 33, ...
Since the pallet P supports the pallet P and is movable integrally with the pallet P, there is no possibility that the pallet P will drop from the traveling carriage 21 and a highly reliable pallet P moving operation can be performed. .

Although the above-described operation is the exit operation of the vehicle C, when the empty pallet P is moved to the entry space SS during the entry operation, the back side space row 8
The same operation is performed when the empty pallet P in the accommodation space S located at the front end of b is moved to the loading / unloading port 9.

In addition, the target vehicle can be transferred to the mounting space of the movable table. Therefore, unlike the conventional case, it is not necessary to secure a space for allowing the protrusion of the movable table in the moving path in advance, and accordingly, the traveling path can be shortened as compared with the conventional one, and the whole device can be provided. The installation space can be reduced. Also,
When one of the plurality of accommodation spaces is set as an empty space and a vehicle in the rear space row is to be unloaded, the pallet in the adjacent space row is moved to the empty space once, and then the pallet in the rear space row is temporarily moved. It is not necessary to place the vehicle on the traveling carriage and move it to the exit port. Therefore, according to the present invention, it is possible to prevent a part of the traveling carriage from protruding from the end of the space row during the leaving operation of the vehicle, and to perform a quick leaving operation of the vehicle at one end of the back space row. It is possible to obtain the mechanical parking facility with high practicality.

According to the second aspect of the present invention, the moving means is provided with the outer roller movable in the extension direction of the moving path and the inner roller movable up and down, and the inner roller is in the raised position. The pallet can be transferred between the accommodation space of the space row group and the mounting space of the movable table, and the outer roller is moved in the extension direction of the moving path with the inner roller being in the lowered position. Thus, since the pallet is moved between the respective mounting spaces, the outer roller is provided with a guide function for transferring the pallet between the accommodation space of the space row group and the mounting space of the movable table, and The pallet supporting function at the time of moving the pallet between the mounting spaces can also be provided, and the above-described claim 1 can be achieved while reducing the number of parts.
The effects according to the invention described in (3) and (3) can be obtained. Also, when moving the pallet between each loading space,
Since the outer rollers support the pallet and move integrally with the pallet, the pallet is not likely to drop from the moving table, and a highly reliable pallet moving operation can be performed.
