Description

Detailed Description of the Invention 3. Detailed Description of the Invention Field of Industrial Application This invention relates to a multi-story parking system in the form of a multi-story safe, which comprises a storage rack and an elevator equipped with a fork device.

Conventional Technology In cities, it is extremely difficult to secure parking lots in terms of both price and area, and the need for effective use of land is increasing.As a countermeasure, various types of multi-level parking systems are being developed. It has been developed and put into practical use.

In particular, many gondola-type multilevel parking systems are being constructed as a type suitable for extremely narrow parking lots. A gondola-type multilevel parking system has two sets of sprockets at the top and bottom, and two sets of conveyor chains are stretched between each sprocket at the top and bottom. It consists of a large number of so-called gondolas that carry cars, and the gondolas are circulated by rotating the sprocket at the top. When entering and leaving the warehouse, other gondolas are hoisted high upwards by conveyor chains while still carrying cars.

In such a device, the total weight of all the gondolas and the weight of the cars loaded on them is loaded on the conveyor chain, so the chain tension acting on the conveyor chain becomes excessive, making it difficult to accommodate a large number of cars. The problem was that it was difficult to do so. Further, when circulating in the gondola, there are cases where cars are unevenly distributed only on one of the ascending side and the descending side, so there is a problem that the output of the drive motor needs to be large.

Purpose of the Invention In view of the actual state of the prior art, an object of the present invention is to reduce the load acting on the elevator by having an elevator carry cars in and out one by one into and out of a multi-tiered car storage space. Since the weight is always the same as one car, the load does not limit the number of cars accommodated, and the output of the elevator drive motor becomes extremely large as the number of cars accommodated increases. The purpose is to provide a new multi-level parking device that does not require the need for parking.

Structure of the Invention In order to achieve the above object, the structure of the present invention is such that an elevator equipped with a fork device is provided in the center of a storage rack in which a plurality of car storage spaces are arranged facing each other and stacked in multiple stages. A storage shelf that supports a pallet that can be loaded with a car is provided in the space, and when the fork device extends into the car storage space and moves up and down, the fork device is arranged so as not to interfere with the storage shelf. The elevator transports the car between the car storage space and the elevator, and the elevator transports the car between the car storage space and the home position on the ground floor. The number of cars being transported up and down at a time is always only one. Therefore, an increase in the number of cars accommodated does not increase the load on the elevator, so the number of cars accommodated is determined by the height of the storage rack. The gist is that the number of car storage spaces can be selected arbitrarily by simply increasing the height and increasing the number of car storage spaces.

Example Examples will be described below with reference to the drawings.

The multi-story parking device has car storage spaces 11.11...

Each tensioner 22G that locks the end of the chain is swingably attached to the frame 12a via a pin 22j, and tension imbalance of the chain 22.23 can be detected by a limit switch (not shown). While it is possible,
It is assumed that both drive devices 24.24 are operated electrically in synchronization.

Two sets of fork devices 30 and 30 are mounted on the lower frame 21a of the elevating frame 21.

Each fork device 30 includes a first stage fork 31 and a second stage fork 32 that are movable relative to each other in parallel in the longitudinal direction.
and a three-stage fork 33 (Fig. 5, Fig. 6),
Each of the forks 31, 32, and 33 is a structure with a generally groove-shaped cross section, and overlaps one another in turn.
Grooves 32a, 32a, 32b, 32 formed on both sides of 2
b, and rollers 31a, 31a, . . . , 33a that are transferred while fitting into these grooves 32a, 32a, 32b, 32b.
, 33a, . . . , and are engaged with each other and assembled integrally. However, rollers 31a, 31a・
..., 33a, 33a... are arranged on both sides of the first stage fork 31 and the third stage fork 33, one each at each end and two at the center, and within the stroke. , 1st stage fork 31 and 2nd stage fork 32
The engagement with the rollers is always made by at least four rollers 31a, 31a..., two on each side, and
Similarly, engagement between the second stage fork 32 and the third stage fork 33 is ensured by rollers 33a, 33a, . . . of at least 4 g. Further, sprockets 36a and 37a are provided at both ends of the second stage fork 32, and between the fastening points 36C137c, 36b, and 37b provided on the first stage fork 31 and the third stage fork 33,
Two chains 36 and 37 connect sprockets 36a and 3
They are stretched across each other through 7a.

Gear trains 34.34a, 34b, 34b driven by a motor (not shown) are attached to the lower surface of the first stage fork 31, and the gear trains 34b, 34b are connected to the second stage fork 32.
When the gear 34 is driven by the motor, the second stage fork 32 moves forward relative to the first stage fork 31, thereby causing the two chains 36. Since one of the fork members 37 is tensed and the other is relaxed, the third-stage fork 33 also moves forward relative to the two-stage fork 32, so that the entire length of the fork device 30 can be extended. Similarly, gear 34
By driving in the reverse direction, the folding device 30 can shorten its length and roughly extend in the opposite direction.

However, one gear 34 is provided for each of the two sets of fork devices 30.30, and they are connected by a connecting shaft (not shown), so that two sets of fork devices 30.30 can be operated simultaneously by one motor. It shall be possible to expand and contract.

When transporting a car C into the multi-story parking system having such a configuration, first, each car storage space 1 except for one car storage space 11 near the home position 15 is loaded.
1.11... Place one pallet 14 on the upper surface of each storage shelf 13.
, 16a. Moreover, the elevator 20 is
The elevating frame 21 is placed on standby at the lowest position.

When carrying in the first car C, the car C is carried in through the entrance E of the multi-story parking system, placed on the pallet 14 at the home position 15, and then the fork device 30, 30 of the elevator 20 is moved below the pallet 14. (indicated by a two-dot chain line in FIG.
Transfer it onto the fork devices 30, 30. Next, the fork device 30 is shortened to position the automobile C in the center of the elevator 20. Subsequently, the elevator 2 is moved up to the car storage space 11 where the pallet 14 is not stored.
0 is raised so that the upper surface of the fork device 30.30 is at a higher position than the upper surface of the storage shelf 13.13, and the elevator 20 is stopped. The fork device 30, 30 is extended toward the inside of the vehicle storage space 11 (indicated by a solid line in the figure), and then the elevator 20 is lowered.
After transferring the car C together with the pallet 14 onto the storage shelf 13.13 of the car storage space 11, if the fork devices 30, 30 are shortened, the car C can be moved onto the pallet 14.
The vehicle is stored in the vehicle storage space 11 in a loaded state.

Here, if the car storage space 11 in which the car C is to be accommodated is on the ground floor opposite the home position 15 with the elevator 20 in between, the pallet 14 and the car C are loaded from the home position 15. It goes without saying that it is sufficient to simply extend the fork device 30° 30 in the direction opposite to the home position 15, that is, in the direction toward the inside of the car storage space 11, and there is no need to raise the elevator 20. .

When the storage of the first car C is completed, empty pallets 14 placed in other car storage spaces 11 as close as possible to the home position 15 are transported to the home position 15 in preparation for carrying in the next car C. do. That is, the elevator 20 is placed in the car accommodation space 1.
1, and stopped the elevator 20 so that the top surface of the fork device 30.30 was lower than the bottom surface of the storage shelf 13.13, extended the fork device 30.30, and continued to move the elevator 20. It ascends and transfers the pallet 14 onto the fork devices 30, 30. Roughly, the fork devices 30, 30 are shortened, the pallet 14 is positioned at the center of the elevator 20, and the elevator 20 is lowered toward the home position 15.

The top of the fork device 30.30 is at home position 15
After stopping the elevator 20, the fork device 30.30 is extended into the home position 15, and the elevator 20 is lowered to the lowest position. 14 can be placed at home position 15.

Next, when transporting the car C, the above procedure can be repeated. Eventually, if the car C is accommodated in all the car storage spaces 11.11..., it will no longer be possible to
Since there is no empty pallet 14 to be placed at the home position 15, the elevator 20 may then stand by at any height.

When carrying out the automobile C housed in the multi-story parking device, if there is a pallet 14 at the home position 15, it is first returned to the original automobile accommodation space 11. This procedure for returning the pallet 14 is as described above.
The procedure for transporting car C is exactly the same. Further, the car C can be carried out using the same procedure as when transferring the empty pallet 14 to the home position 15 as described above. The vehicle C may be transported to position 15, and then the vehicle C may be driven backwards and taken out from the entrance E of the multi-story parking system.

Subsequently, when taking out another car C@@, it is enough to repeat the above procedure, and when bringing in another car C, use the pallet 14 in the home position 15 as is and carry out the above-mentioned carry-in. The procedure allows the operation to be performed.

In addition, since a turntable 18 is provided in the immediate vicinity of the entrance E of the multi-story parking system, the automobile C immediately after being carried out can be placed on this turntable 18 and its direction can be changed.

Another Example On the ground floor of the storage rack 10, a rotating device 40 that can be raised and lowered can be provided directly below the elevator 20 (
Figures 7 to 9).

Here, the entire ground floor is set as the home position 17 so that the pallet 14 can be rotated by the rotation device 40 on the ground floor, and at the center of one side of the storage rack 10 parallel to the elevator 20. An entrance/exit G is provided (Fig. 7). Also, home position 1
A pit 17b for housing the rotating device 40 is formed in the center of the floor surface 17a of the elevator 20 (FIG. 8), and a pit 17b for storing the pallet 1
Concave portions 17c, 17c are formed so that 4 can be placed therein.

The turning device 40 includes a pantograph-type lifting mechanism 41 and a rotating mechanism 42 mounted on a top plate 41a of the lifting mechanism 41 (FIG. 9). The rotation mechanism 42 has a built-in gear mechanism that can rotate the rotating base 42a that supports the pallet 14 with respect to the top plate 41a of the lifting mechanism 41 by a drive motor (not shown). The top plate 41a has guide rollers 41d, 41
d... is provided, and the pallet 14 is rotated by the rotating mechanism 42.
The stability of the pallet 14 can be ensured when the pallet is rotated (Fig. 8).

On the other hand, at the lowest position of the elevator 20, the lower frames 21a, 21a of the elevating frame 21 can be lowered into the pit 17b with the rotating device 40 in between, and the elevating mechanism 41 is lower than the rotating base 42a. upper pallet 14
, the fork device 30 of the elevator 20 at the lowest level,
30, and the rotation mechanism 42 can rotate the pallet 14 at that position (as shown by the two-dot chain line in FIG. 9). In the elevator 20,
Fork device 30.Parallel with 30, plan]・Home 2
1d and 21d are provided (Fig. 7).

In such a configuration, the recess 17G in the floor surface 17a is perpendicular to the elevator frame 21 of the elevator 20 that is required to be at the lowest level.
, 17C is facing the entrance/exit G, so the automobile C carried in through the entrance/exit G can be smoothly transported.
It can be parked on the pallet 14, and once the car C is parked on the pallet 14, the driver of the car can get off on the platform 21d. Thereafter, the pallet 14 is raised by the lifting mechanism 41, rotated by 90 degrees by the rotating mechanism 42, the pallet 14 is oriented in the same direction as the lifting frame 21, and then the lifting mechanism 41 is lowered. With C loaded,
Since it is placed on the fork device 30.30 of the elevator 20, the elevator 20 can then be ascended to carry the automobile C into a predetermined automobile accommodation space 11.

When transporting the automobile C, the elevating mechanism 41 is raised before the elevator 20 is lowered to the home position 17. When the elevator 20 loads the automobile C onto the pallet 14 and descends to its lowest position, the turning base 42a of the rotating mechanism 42 protrudes higher than the fork device 30, 30, so the pallet 14 Naturally, it is transferred from the fork device 30, 30 onto the swing base 42a. Therefore, the pallet 14 is rotated 90 degrees by the rotating mechanism 42 to direct the automobile C on the pallet 14 toward the entrance G, and then the lifting mechanism 41 is lowered, and the pallet 14 is moved to the floor surface 17a.
After that, the vehicle C is started and the vehicle C is carried out through the entrance G.

As described above, according to this embodiment, since the turning device 40 is housed and provided in the storage rack 10, there is no need to provide an external turntable 18 for changing the direction of the automobile C. In addition to being suitable for construction in a narrow space, it is extremely advantageous in terms of safety since there is no need to drive the car C backwards during removal.

Note that the pallet 14 in this embodiment has an inter-vehicle distance M and wheel bases L1 and L2 of the automobile C on its upper surface.
Taking into account the grooves 14a, 14a and the recess 14 for guiding the tires T, T... and stably holding them.
b, 14b, etc., but it goes without saying that such a pallet 14 can also be used in the previous embodiment.

As described in detail, according to the present invention, an elevator is provided in the center of the storage rack, and a fork device mounted on the elevator is used to transfer pallets between the elevator and the car storage space in the storage rack. At the same time, the load on the elevator is reduced by having the elevator transport each car loaded on a pallet vertically between the car storage space and the home position on the ground floor. Regardless of the total number of cars accommodated, the weight of the surrounding area is always just the weight of one car, so even if the system is large-scale and accommodates a large number of cars, the load on the elevator will not be excessive. Therefore, there is an excellent effect that a small output of the elevator drive motor is sufficient.

In addition, the elevator for transporting cars and the storage rack for storing cars are each independent systems and are not systems that share both functions like the gondola system, so the number of cars that can be accommodated is limited. In order to increase the number of cars, it is sufficient to simply increase the height of the storage rack and increase the number of car storage spaces, and the elevator itself does not require any basic modification, just increasing its lifting stroke. Since there is no such thing, it has the excellent effect that it is extremely easy to construct a system that can accommodate an optimal number of units.
