2. Description of the Related Art As shown in FIGS. 14 and 15, for example, a conventional multi-story parking system has a parking area 3 on the ground floor where cars 2 enter and exit, and a pallet lifting area extending upward from the area 3. 4, a plurality of garage areas 5 are stacked along both sides of the area 4, and the pallet lifting area 4 is provided with a pallet lifting device for lifting and lowering the pallet lifting member 39 in the area 4 and the loading/unloading area 3. In addition, a pallet traversing device (not shown) is known in which each garage area 5 is provided with a pallet traversing device (not shown) for traversing pallets between the garage area 5 and the pallet lifting area 4. The pallet lifting member 39 generally includes:
One has a rectangular body structure and is configured to be raised and lowered with the pallet 1 placed and supported, and the other has a rectangular frame structure in which four hook bodies that engage and disengage from the four corners of the pallet 1 are vertically disposed. Some devices are configured to raise and lower the pallet 1 in a suspended and supported state. Note that the number of pallets 1 corresponds to the number of garage areas 5 installed. Therefore, when the pallet 1 is in the storage area 3 or the pallet lifting area 4, the first garage area where the pallet 1 does not exist (
5a (hereinafter referred to as "garage area where warehousing is possible") exists.

[0003] In such a conventional device, the vehicle 2
The loading/unloading process is as follows:

That is, when the car 2 enters the warehouse, as shown in FIG. 14, when the car 2 enters onto the pallet 1 waiting in the warehouse area 3 (see the chain line in figure A), the pallet lifting member 39 is moved by a predetermined amount. The pallet 1 on which the car 2 is mounted (hereinafter referred to as "car-mounted pallet") is brought to a position in the parking area 5a (see solid line in Figure A), and the car-mounted pallet 1 is then moved to the pallet lifting area 4. The pallet is transferred from the pallet lifting member 39 to the pallet traversing device, and then carried into the garage area 5a where it can be stored (see Figure B). Subsequently, move the pallet lifting member 39 to the car 2.
(hereinafter referred to as the "empty pallet") 1 is raised or lowered to the position of the garage area (hereinafter referred to as the "pallet storage garage area") 5b where the pallet (hereinafter referred to as the "empty pallet") 1 is stored.
(See Figure C), the empty pallet 1 is transferred to the pallet lifting area 4 by the pallet traversing device, and is delivered from the pallet traversing device to the pallet lifting member 39 (see Figure D), and then the pallet lifting member 39 is lowered, Empty pallets 1 are brought to the warehousing/receiving area 3 in preparation for the next warehousing (E
(see figure).

[0005] Furthermore, when leaving the car 2, the process shown in FIG.
As shown in FIG. 2, the pallet lifting member 39 supporting the empty pallet 1 is raised from the storage area 3 to the garage area 5a where the empty pallet 1 can be accessed, and the empty pallet 1 is transferred from the pallet lifting member 39 to the pallet traversing device in the pallet lifting area 4. Then, the empty pallet 1 is carried into the parking garage area 5a by the pallet traverse device (see diagram B). Subsequently, the pallet lifting member 39 is moved to the vehicle 2 that has been requested to leave the warehouse.
(refer to Figure C),
The vehicle-mounted pallet 1 is carried out from the delivery request garage area 5c to the pallet elevating area 4 by the pallet traversing device, and is further transferred from the pallet traversing device to the pallet elevating member 39 (D
(see figure). Then, the pallet elevating member 39 is lowered to bring the vehicle-mounted pallet 1 to the loading/unloading area 3 (see Figure E).

[0006]

However, in the above-mentioned conventional device, when the vehicle 2 is taken in and out of the warehouse, in addition to the original loading and unloading process, the empty pallet 1 is moved to the loading and unloading area 3 and the pallet elevating area 4. A process (hereinafter referred to as the "pallet processing process") is required to transport the pallet between the pallet and the pallet. That is, at the time of warehousing, after performing a warehousing process in which the vehicle-mounted pallets 1 are transferred from the warehousing area 3 to the warehousing garage area 5a, the empty pallets 1 necessary for the next warehousing are transferred to the pallet storage garage area 5b.
It is necessary to carry out a pallet processing step in which the pallets are replenished and transferred from the pallet through the pallet lifting area 4 to the warehouse loading/unloading area 3 (see FIG. 14). In addition, at the time of leaving the warehouse, before carrying out the leaving process of transferring the car-mounted pallet 1 from the dispatch request garage area 5c to the loading/unloading area 3, excess empty pallets 1 that will be an obstacle to loading/unloading are removed from the loading/unloading area 3. It is necessary to carry out a pallet processing process in which the pallets are discharged and transferred to the garage area 5a through the elevating area 4 (see FIG. 15).

[0007]The time required for such a pallet processing step is determined by the pallet lifting distance between the storage area 3 and the storage area 5a or pallet storage area 5b, that is, the distance between the storage area 3 and the storage area 5a or pallet storage area 5b. The garage area 5a varies greatly depending on the location.
, 5b, the pallet processing process may take a long time.

[0008] Therefore, it takes a long time to take one car in and out of the warehouse, and when the parking lot is continuously carried out during rush hours, it is not possible to carry out the parking efficiently and it is impossible to cope with the situation.

[0009] The present invention has been made in view of the above points, and an object thereof is to provide a three-dimensional garage device that can shorten the time required for the pallet processing process as much as possible and can efficiently carry out continuous loading and unloading. This is the purpose.

0010

[Means for Solving the Problems] In order to achieve the above object, the three-dimensional garage apparatus of the present invention, in particular, forms a pallet storage area adjacent to the loading/unloading area, and in the pallet storage area,
It is proposed to provide a pallet transfer device that can transfer pallets between a pallet storage area and a storage area and deliver them to a pallet lifting/lowering device.

[0011]

[Operation] The pallet processing process is carried out between the warehousing/receiving area and the pallet storage area, which are adjacent to each other without any positional change. Therefore, the time required for the pallet processing process is significantly reduced compared to the case where empty pallets are moved between the storage area and the garage area where the position can be changed or the pallet storage garage area via the pallet lifting area. can do.

12' is set to be as small as possible within the range that it can pass through.

As shown in FIGS. 1 and 2, the pallet storage area 30 stores an appropriate number of pallets 1... stacked in two rows on the left and right (hereinafter, the stacked pallet group will be referred to as "stacked pallets 1'"). ) is formed like this. The number of pallets 1 to be stored is set according to the number N of pallets installed in the garage area 5, and is set to at least (N-1) pallets. In other words, in the initial state where there are no incoming cars, pallets 1 in the garage area 5 are kept on standby in the loading/unloading section 3b.
All of them are stored in the storage area 30, so that the entire garage area can be used as a garage area 5a where pallets can be stored.

As shown in FIGS. 1 and 2, the pallet transfer device 40 is disposed between the left and right stacked pallets 1', 1' in the pallet storage area 30, and loads the pallet 1 and rotates it 180 degrees. A turntable 41 that can be horizontally rotated, a table lifting mechanism 42 that lifts and lowers the turntable 41, and a turntable 41 and each stacked pallet 1.
A pallet delivery mechanism 43 that delivers the pallet 1 to and from

4,44. The table elevating mechanism 42 is composed of a lifter and the like, and the turntable 41 is moved between a loading/unloading standby position (solid line position in FIG. 1) where the pallet 1 is located in the loading/unloading section 3b and a pallet delivery position (solid line position in FIG. 1) which is a predetermined amount lower than this position. (the position indicated by the chain line in the figure). Each pallet delivery mechanism 43 is equipped with an adsorbent 43a such as an electromagnet that moves horizontally between the upper surface of the turntable 41 brought to the pallet delivery position and the stacked pallet 1' and moves up and down. When the suction body 43a descends to the pallet delivery position, the suction body 43a descends (or moves horizontally or descends) to suction the uppermost pallet 1 of the stacked pallets 1' (or the pallet 1 on the turntable 41), and then the suction body 43a
a rises and moves sideways to move the pallet 1 onto the turntable 41.
(or the laminated pallet 1'), further lower the pallet 1, and release the adsorption action by the suction body 43a to move the pallet 1 from the laminated pallet 1' to the turntable 41 (or from the turntable 41 to the laminated pallet 1). It is configured to be transferred and supplied to a pallet 1'). Each elevating table 44 is composed of a lifter or the like, and by adjusting the upper surface of the stacked pallets 1' up and down according to an increase or decrease in the number of stacked pallets, the upper surface of the turntable 41 when located at the pallet delivery position can be adjusted. Keep it at approximately the same height.

In the multi-story parking system constructed as described above, the parking of the car 2 is carried out in accordance with the procedure shown in FIG. 7.

That is, when the car 2 enters the pallet 1 waiting in the loading/unloading area 3, the pallet 1 mounted on the car is rotated 180 degrees by the turntable 41, and a set of pallets moved to the pallet receiving position is rotated by the turntable 41. It is supported by the claw bodies 12 (see figure A) and is raised by the claw bodies 12 (
(See Figure B). Then, when the car-mounted pallet 1 rises to the position of the parking garage area 5a and is stopped, the cart 22 of the pallet traverse device 7 moves sideways from the parking garage area 5a to the lifting area 4 and lowers the car-mounted pallet 1. The vehicle-mounted pallet 1 is received and supported by the truck 22 (see Figure C). Thereafter, the trolley 22 returns to the parking garage area 5a, and the vehicle-mounted pallet 1 is carried from the pallet lifting area 4 to the parking garage area 5a, completing the parking process (see Figures D and E).

On the other hand, when the car-mounted pallet 1 is supported by the pawls 12, the turntable 41 is lowered from the loading/unloading standby position to the pallet delivery position by the table lifting mechanism 42 (see Figure B). Then, the uppermost empty pallet 1 of the stacked pallets 1' is supplied by the suction body 43a onto the turntable 41 brought to the pallet delivery position (see Figure C). When the empty pallet 1 is supplied onto the turntable 1, the turntable 41 is raised and returned to the loading/unloading standby position by the table lifting mechanism 42, and the pallet processing process is completed (see Figures D and E).

Further, the vehicle 2 is taken out of the garage in accordance with the procedure shown in FIG.

That is, when there is a request for exiting the warehouse, the claw body 12
... to the pallet receiving position, and raise or lower it to the position of the garage area 5c for requesting delivery (see figure A).
. Then, the vehicle-mounted pallet 1 is transferred from the delivery request garage area 5c to the pallet elevating area 4 by the cart 22 and supported by the claw bodies 12 (see figures B and C).
..., after the cart 22 returns to the garage area 5, it is lowered to the garage area 3 (see Figure D).

During this time, the turntable 41 is lowered to the pallet delivery position, and the pallet 1 on the turntable 41 is moved to the stacked pallet 1 by the suction member 43a.
´Discharge upward (see figures A to D).

When the pallet 1 on the turntable 41 is removed, the turntable 41 ascends and returns to the loading/unloading standby position (see Figures C and D), and the pallet 1 mounted on the vehicle that has descended
(See Figure E), and the shipping process and pallet handling process are completed.

In this way, the pallet handling process can be quickly carried out between the loading/unloading area 3 and the adjacent pallet storage area 30 without using the pallet lifting/lowering device 6, and can be started simultaneously with the loading/unloading process. Therefore, the vehicle 1 can be taken in and out of the garage extremely efficiently.

By the way, the claw body 1 for raising and lowering the pallet 1
2. Even when the pallet 1 is present in the pallet lifting area 4, when it comes to be supported by the pallet traversing device 7, it is moved beyond the pallet 1 to the desired position by bringing it to a position where the pallet does not interfere with the pallet. It can be raised and lowered up to. Therefore, in conjunction with the fact that the pallet processing process can be carried out quickly as described above, the positional relationship between the garage area 5a that can be entered and the garage area 5c that is requested to leave, and the garage area that can be entered 5a... mutually or the garage area 5c that is requested to leave... Regardless of the mutual positional relationship, the next loading/unloading process can be started at the stage when the vehicle-mounted pallet 1 receives support from the pallet traversing device 7 in one loading/unloading process. In other words, two loading and unloading processes can be performed in parallel using one set of claw bodies 12. For example, at the stage of diagram C in Figure 7,
The claw bodies 12... can be raised to the upper garage area 5c, and the garage exit process can be started.

Therefore, if the pallet 1 is raised and lowered by the claws 12 that move in and out of the pallet raising and lowering area 4, it becomes possible to respond even more quickly even when the store is loaded and unloaded continuously. Two or more sets of claw bodies 12
..., 12'... are provided, this becomes more noticeable.

The multilevel parking system according to the present invention is not limited to the above-mentioned embodiments, and can be modified and improved as appropriate without departing from the basic principles of the present invention.

For example, in the second embodiment shown in FIG.
, 8' existing in the loading/unloading area 3 have been eliminated. That is, in the loading/unloading area 3, each elevating body 11, 1
With at least the upper end side of the pallet 1' being supported by the guide rails 8, 8', each pallet elevating member 9, 9' can be raised and lowered without any trouble (see chain line illustration), and each The pallet elevating member 9 can be completely raised and removed from the storage area 3 (see solid line diagram).
.

By the way, the entrance 3 in the loading/unloading area 3
a. In other words, the left-right distance between the front guide rails 8', 8' cannot be kept smaller than a certain level due to certification standards, so when the number of pallet lifting member groups 9..., 9'... increases, the nails inevitably become loose. The horizontal width of the pallet 1 supported by the bodies 12..., 12'... becomes larger than necessary,
As a result, there is a risk that the car 2 may skid on the pallet 1 when going up and down, or the device may become larger, reducing the efficiency of land use.

However, if the configuration is as described above, the car 2
can move forward and backward into the loading/unloading area 3 without the presence of guide rails 8..., 8'... or pallet lifting members 9..., 9'..., and the number of installed pallet lifting members 9..., 9'... Even if the number of pallets increases, the left-right distance between the guide rails 8 can be made small, and the left-right width of the pallet 1 can be minimized, regardless of the above-mentioned certification criteria.

Further, in the third embodiment shown in FIGS. 10 to 13, the portion of the guide rails 8 existing in the loading/unloading area 3 is eliminated, as in the second embodiment, but the same Differently, in the loading and unloading area 3, the lifting and lowering of the pallet 1 is
This is done not by the pallet lifting member 9, but by a separately provided auxiliary lifting device 50 such as a lifter. This sub-elevating device 50 moves the turntable 41 to a loading/unloading standby position (position shown in FIG. 10) which is the lower end position of the loading/unloading area 3 and a pallet loading/unloading standby position (position shown in FIG. 10) which is the lower end position of the loading/unloading area 3 or the lower end position of the pallet lifting area 4. The transfer position (position shown in figure B in FIG. 12) is raised and lowered. moreover,
Pallet storage areas 31a and 31b capable of storing one pallet 1 are formed below the loading and unloading areas 5 and 5 at the lowest stage, and the pallet traversing device 7 is provided in each area 31a and 31b.
A pallet transfer device 51 having the same structure as that is provided,
When leaving the warehouse, the empty pallets 1 waiting in the loading/unloading section 3b are discharged to the first pallet storage area 31a by the sub-elevating device 50 and the pallet transfer device 51, and when entering the warehouse, the empty pallets 1 are discharged to the first pallet storage area 31a. The pallets 1 stored in the warehouse are supplied to the storage area 3 by a sub-elevating device 50 and a pallet transfer device 51. In this way, the horizontal width of the pallet 1 can be minimized as in the third embodiment, and the pallet processing process can be carried out efficiently as in the first embodiment.

In this embodiment, the parking of the car 2 is as shown in FIG.
The procedure is as shown in 2. In other words, the warehouse area 3
When the car 2 enters the pallet 1 that is waiting, the pallet 1 mounted on the car is rotated 180 degrees by the turntable 41 and raised by the auxiliary lifting device 50, and is moved to the boundary between the loading/unloading area 3 and the pallet lifting area 4. In this area, the pallet is transferred from the turntable 41 to the pawls 12 that have been moved to the pallet receiving position (see Figures A and B). Then, the car-mounted pallet 1 can be stored in the garage area 5 by the claw bodies 12...
The cart 22 of the pallet traversing device 7 is raised to the position a.
traverses from the storage area 5a to the lift area 4 and enters under the car-mounted pallet 1, where it is received and supported by the truck 22 (see Figure C). After that, trolley 22
The pallet 1 returns to the parking area 5a, and the vehicle-mounted pallet 1 is carried from the pallet lifting area 4 to the parking area 5a, completing the warehousing process (see Figures D and E).

During this time, when the vehicle-mounted pallet 1 is transferred from the turntable 41 at the pallet transfer position to the claw bodies 12, the pallet 1 is transferred from the second pallet storage area 31b to the turntable 41 by the pallet transfer device 51.
It is transferred and supplied to the top (see Figures C and D), and
0, the turntable 41 is lowered back to the warehousing/unloading standby position to prepare for the next warehousing (see figure E). Furthermore, when the vehicle-mounted pallet 1 is supported by the pallet traversing device 7 (see Figure C), the claw bodies 12 move to the pallet non-interference position and temporarily exit the pallet lifting area 4.
The pallet 1 and the pallet traversing device 7 are mounted on the vehicle as is.
, and rises to the position of the pallet storage garage area 5b (see Figure D). Then, the pallet 1 is moved from the pallet storage garage area 5b to the claw body 12 by the pallet traversing device 7.
When delivered to the second pallet storage area 3, the claw bodies 12...
1b and replenishes the pallet 1 to the second pallet storage area 31b by the pallet transfer device 51 (
(See figure E).

[0042] Further, the car 2 is taken out of the garage in accordance with the procedure shown in Fig. 13. In other words, when there is a request for delivery, the claw body 1
2... is moved to the pallet receiving position and raised or lowered to the position of the garage area 5c for which the request for delivery is requested (see Figure A). Then, the vehicle-mounted pallet 1 is transferred from the delivery request garage area 5c to the pallet lifting area 4 by the cart 22, supported by the claws 12, and then lowered after the cart 22 returns to the garage area 5 ( (See Figure B).

During this time, the turntable 41 is raised to the pallet delivery position (see the chain line in Figure A), and the pallet 1 on the turntable 41 is discharged to the first pallet storage area 31a by the pallet transfer device 51 (see Figure B). .

Then, the car-mounted pallet 1 that has been lowered by the claws 12 is transferred onto the turntable 41 from which the empty pallet 1 has been ejected (see Figure C), and the claws 12 are placed in a position that does not interfere with the pallet. After operating and leaving the elevating area 4, the sub-elevating device 50 lowers the loading/unloading area 3 to the loading/unloading section 3b to complete the loading/unloading process (Figures D and E).
(see figure).

On the other hand, the pawls 12 are returned to the pallet receiving position when the car-mounted pallet 1 descends and passes through them, and the pallet 1 is transferred to the first pallet by the pallet transfer device 51.
After receiving the pallet from the pallet storage area 31a, it ascends to the parking garage area 5a (see Figure E). Then, the pallet 1 can be stored in the garage area 5a by the pallet traversing device 7.
to be transported to.

Of course, in this embodiment as well, a plurality of sets of pallet lifting/lowering members 9 can be provided, and the efficiency of loading and unloading can be further improved. In this case, at least one set of pallet lifting/lowering members 9 can be used exclusively for lifting and lowering the empty pallet 1, but this has the advantage that the drive mechanism 10 dedicated to the empty pallet can be of low output. .

Furthermore, in each of the above embodiments, the pallet 1 is raised and lowered by the four claws 12.
As the pallet lifting device 6, the well-known device mentioned at the beginning can also be used. In addition, the pallet traveling device 7
The pallet transfer device 51 may not use the self-propelled cart as described above, and its configuration is arbitrary.

[0048]

[Effects of the Invention] As is clear from the above explanation, according to the present invention, the pallet processing process can be carried out quickly.
Lost time in loading and unloading can be reduced as much as possible. Therefore, loading and unloading can be carried out efficiently, and even when it is necessary to carry out loading and unloading continuously, it is possible to respond quickly.
