Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to an automobile parking device, and particularly to a novel automobile parking device that can improve land use efficiency in order to effectively utilize narrow land. .

BACKGROUND OF THE INVENTION In cities, because land is limited, car parking lots are often constructed as underground facilities of buildings and other structures. The most common type of underground parking lot is a parking lot with an entrance that opens toward the street, and a slope that allows cars to drive.
The entrance and exit are connected to a designated underground floor that serves as a parking space, and when parking a vehicle, the driver drives the vehicle through the slope to reach the designated underground parking space. After driving the car and parking it at a predetermined location, the driver returns to the ground level using stairs or an elevator.To carry the car out, the driver must park the car again and then return to the basement floor where the car was parked. You go there, drive your car through a slope, and then you come out on the ground.

However, the biggest problem associated with such general underground parking lots is low land use efficiency, and the underground parking space has ramps and running ramps for cars to move in and out of the parking lot. It is not only necessary to secure passageways, but also to maintain a ceiling height sufficient for drivers to walk on each floor, as well as to provide elevators, stairs, etc. as passageways for drivers to connect with the ground. As a result, the effective parking area would be greatly reduced.

Therefore, in order to solve the problems in such general underground parking lots, the applicant first constructed storage racks for storing cars in the underground space and used a stacker crane to store cars. By transporting the vehicle, the driver does not have to enter the underground parking space.
Therefore, we proposed a car parking system that can maximize land use efficiency since there is no need to provide incidental spaces such as slopes and passages for cars to run within the parking lot space (Patent Application No. 6L-198307 ) The problem to be solved by the invention is that a storage rack constructed in an underground parking space consists of two rows of stacked car storage spaces facing each other. The stacker crane was installed in the center of the rack, so if you wanted to increase the number of cars that could be accommodated, you could either raise the storage rack higher to increase the number of stacked cars in the car storage space, or make the storage rack longer. Since the only option available is to increase the number of car storage spaces stacked on top of each other, the problem remains that it is not always easy to realize a parking space with a specified number of parking spaces. .

Therefore, in view of the actual state of the prior art, an object of the present invention is to provide two or more sets of storage racks, connect them by a horizontal pallet transfer device, and install a stacker crane for each set of storage racks. By arranging this, vehicles can be moved between each set of storage racks, so by increasing the number of sets of storage racks as needed, it is possible to easily construct a system of any size. Our goal is to provide a new car parking device.

Means for Solving the Problems In order to achieve the above object, the present invention has a structure in which a plurality of car storage spaces are stacked in multiple stages, and these are arranged in two rows facing each other to form storage racks. In addition, two or more sets of these storage racks are arranged in parallel, and a stacker crane equipped with a telescopic fork device is installed in the center of each storage rack, so that the storage racks in each storage rack are placed behind each other. The gist is that at least one set of vehicle storage spaces adjacent to each other are connected via a horizontal pallet transfer device.

Accordingly, with the above configuration, a car stored in one of a pair of car storage spaces connected by a horizontal pallet transfer device, while being loaded on a pallet,
Since it is possible to transfer the vehicle to the other vehicle storage space, the vehicle can be moved freely between the storage racks that are arranged parallel to each other. After this, the stacker crane attached to the storage rack makes it possible to store the car in any car storage space in the storage rack, so any set of storage racks can be installed as needed. By doing so, it is possible to easily realize a predetermined number of parking spaces.

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

The car parking device includes a lift device 10, storage racks 30, 30 formed of two opposing rows of multi-tiered car storage spaces 35, 35, and each storage rack 30.
, 30 stacker cranes 20, 20 installed in the center of
and a horizontal transfer device 40 for pallets P (FIGS. 1 and 2).

The lift device 10 is installed in a building E that has a blowout structure from above the ground level GL to underground.
An elevating body 14 that is raised and lowered by a hydraulic cylinder 11
The elevating body 14 is guided by guide masts 12, 12 and can be moved up and down by the operation of the hydraulic cylinder 11. Lifting body 1
4 has a cantilevered shelf 14a protruding from it (Fig. 1).
, a platform 14G and a spacer 1 are placed on the shelf 14a.
4b, and a pallet P for loading the automobile C can be placed on top of the spacer 14b.

The platform 14G is set at approximately the same height as the upper surface of the pallet P on the spacer 14b, and forms a walking path for the driver who ascends and descends from the automobile C.

An entrance EX is opened at a position facing the longitudinal direction of the lift device 10 of the building E (Fig. 2), and a car C to be carried in enters the entrance EX by driving from the road.
When the elevating body 14 of the lift device 10 is at the home position HP close to the ground level GL, the height of the home position HP is set so that it can stop directly on the pallet P ( Figure 1). Further, the lift device 10 operates downward from the home position HP to the delivery position TR, which is set at least at a position sufficiently lower than the vehicle height of the automobile C, as the lifting and lowering stroke of the elevating body 14. do.

Each storage rack 30 is formed by stacking car storage spaces 35, 35, etc., each capable of storing one car C, in two rows facing each other (Fig. 1, Second
In other words, the storage rack 30 is a structure built by pillars 31, 31... in the parking lot space S, and the pillars 31, 31... are arranged at predetermined heights. Support plates 32, 32, . . . for receiving the pallets P are fixed to the columns 31, 31, .
Each space separated by the pallet PXP supported on the upper surface of 32... is a car storage space 35.35 for storing and accommodating one car C at a time.
... is formed. In this embodiment, the storage rack 30.30 has three car storage spaces 35.35 on each side in the parking lot space S, excluding the space for raising and lowering the lift device 10. They are formed in two rows facing each other, and two sets are provided in parallel across the pillars S1, Sl, etc. in the parking space S, but the number of stages and the number of sets at this time are as follows. Each of these can be arbitrarily selected depending on the desired number of parking spaces.

The stacker crane 20 is attached to each of the storage racks 30 formed in two rows inside the underground parking space S, and its center portion is guided by guide rails 21a, 21a at the upper and lower ends. A main body 22 that can be raised and lowered is provided between two moving masts 21.21, and a fork device 23.23 is mounted on this main body 22 (FIGS. 1 and 2). The fork device 23.23 is extendable and retractable on both sides in a direction perpendicular to the traveling direction of the stacker crane 20, and after being extended so as to be inserted into the lower surface of the pallet P, the main body 22 is raised. If you force me,
In order to transport the automobile C loaded on the pallet P, it is assumed that the automobile C can be transferred onto the fork device 23.23.

A horizontal transfer device 40 for pallets P is disposed between the two sets of storage racks 30, 30. The horizontal transfer device 40 is included in each storage rack 30 and is configured to move a pallet with or without a car C loaded between a pair of car storage spaces 35 and 35 adjacent to each other facing away from each other. A device that can horizontally reciprocate P,
It is driven by two geared motors 41 and 41 with brakes.

In other words, the horizontal transfer device 40 includes two geared motors 41.41, a guide rail 42.42, a pair of moving bodies 44.44, and a pinion 4 that drives the moving bodies 44.44.
3.43... are the main components. The gad motor 41.41 is located in the adjacent automobile storage space 3 facing backwards.
5.35, and the rotational force of each gad motor 41 is transmitted through the transmission chains 41a, 41b,
41G, the pinion 43 is arranged in both vehicle storage spaces 35, 35 and in the gap d, respectively.
．． 43... (Figures 3 and 4).

The guide rail 42.42 has a car storage space 35.3
The pallet P is placed at the same height as the support plate 32.32 for supporting both ends of the pallet P in the other car storage spaces 35.35... Each of these is a long member with a groove-shaped cross section supported via another support plate 42f similar to the support plate 32 and an angle frame 42e so as to be able to support the support plate 32 (FIG. 4). The total length of the guide rail 42 is sufficient to reach the front ends of the vehicle storage spaces 35, 35 on both sides, and parallel protrusions 42b, 42b are formed on both side edges of the upper surface. A sliding plate 42C142C having a small coefficient of friction is attached to the upper surface of the parallel protrusions 42b, 42b. In addition, geared motor 4
The pinions 43, 43... driven by 1 are:
It is pivoted on the upper surface of the support plate 42f directly below the guide rail 42, and each pinion 43 has a parallel protrusion 42b14.
It is assumed that a portion of the guide rail 42 is exposed above the guide rail 42 through a square hole 42d formed between the guide rails 2b and 2b.

The movable body 44 is a long member that can slide on the upper surface of the guide rail 42 (FIGS. 4 and 5), and has a rack on the back surface of the plate 44a with both ends formed as slopes. 44
b is attached, and stop plates 44C144C, each having an obliquely bent protruding edge toward the top surface, are screwed onto both end surfaces. The total length of the moving body 44 is slightly longer than the total width of the pallet P, and the rack 44b on the back side fits into the groove formed between the parallel protrusions 42b, 42b of the guide rail 42, It meshes with a pinion 43 exposed above through a square hole 42d from below. Further, the lower surface of the movable body 44 is connected to the guide rail 42.
The pinion 43 is in contact with the upper surface of the sliding plate 420.42C.
As shown in FIG. 6, it is possible to freely reciprocate along the guide rail 42 by rotating the guide rail 42.

Pinions 43.43... are connected to a set of car storage spaces 35.35 by guide rails 42.42.
One guide rail 42 is provided within the guide rail 42, and one guide rail is also provided within the gap d between them (FIG. 3). Here, each pinion 43.
The distance between the axes of 43... is shorter than the length of the moving body 44, and the two guide rails 42.42 are connected to both ends of the pallet P via the moving bodies 44.44 on the upper surface thereof. It is assumed that the pallets P are arranged in parallel with an interval slightly shorter than the entire length of the pallet P so as to be able to support the pallets P.

When using a car parking device with such a configuration, first,
The lift device 10 is placed at the home position HP with one pallet P placed on the shelf 14a of the elevating body 14, and is placed in a stacker attached to the storage rack 30 on the side where the lift device 10 is installed. The crane 20 waits with its main body 22 located at a position facing the delivery position TR of the lift device 10. In addition, at this time, in each car storage space 35.35..., a pallet P for each of the two storage ranks 30.30 is placed, excluding any one of them. Shall be dark.

The first car C to be stored in the car parking device enters from entrance EX in the direction of the arrow in FIG.
Fig. 2). After setting the parking brake of the automobile C, the driver gets off the vehicle onto the platform 14C of the lift device 10 and exits the vehicle.

Next, the elevating body 14 of the lift device 10 with the car C loaded thereon is moved from the home position HP to the delivery position TR.
It is lowered to . At the position opposite to the delivery position TR,
Since the main body 22 of the stacker crane 2Q is on standby, if the fork devices 23, 23 of the stacker crane 20 are extended toward the lift device 10 in this state,
The fork device 23.23 is inserted into the gap between the shelf 14a and the pallet P formed by the spacer '14b of the lifting device 10 (FIG. 1). Therefore, if the main body 22 of the stacker crane 20 is slightly raised,
The automobile C loaded on the pallet P can be smoothly transferred from the lift device 10 to the stacker crane 20.

Next, when the fork devices 23, 23 are shortened and the vehicle C is placed in the center of the stacker crane 20, the stacker crane 20 can travel along its travel route along the guide rails 21a, 21a. Moreover, since the main body 22 of the stacker crane 200 can be moved up and down arbitrarily along the mast 21.21, the stacker crane 20 can move the automobiles loaded on the stacker crane 20 through its traveling and up/down operations. C can be transported to the front position of any one of the vehicle storage spaces 35, 35, . . . included in the storage rack 30 on the side corresponding to this stacker crane 20.

Therefore, here, it is assumed that the car C is transported to the front of the car storage space 35 where the pallet P is not arranged, and then the fork device 23, 23 is extended toward the inside of the car storage space 35. Then, by slightly lowering the main body 22 of the stacker crane 20, both ends of the pallet P on which the automobile C is loaded are lifted.
Support plate 32.3 corresponding to the vehicle storage space 35
2, the vehicle C can be stored in the vehicle storage space 35.

After storing the car C in the car storage space 35, move the stacker crane 20 with the fork device 23, 23 shortened to the front of another arbitrary car storage space 35,
The pallet P placed in the vehicle storage space 35 is carried out by the fork device 23.23. Thereafter, the stacker crane 20 is moved to a position facing the lift device 10 necessary for the delivery location TR, and the above-mentioned car C
After the pallet P is placed on the lift device 10 by a completely reverse procedure to the carrying-in procedure, the lift device 10 is returned to the home position HP in preparation for carrying in the next automobile C.

When transporting the car C, if a car storage space 35 for storing the car C cannot be found in the storage rack 30 on the side where the lift device 10 is formed, a horizontal transfer device 40 for the pallet P is used. That is, when the automobile C loaded on the pallet P is transferred onto the stacker crane 20 from the delivery position TR of the lift device 10, it is immediately transferred to the automobile storage space 3 facing the delivery position TR.
Store in 5. However, at this time, the movable bodies 44, 44 of the horizontal transfer device 40 are moved to this car storage space 35 in advance, and therefore, the pallet P loaded with cars C is moved to this car storage space 35.
5, both ends of which are supported by the upper surface of the moving body 44.44.

Next, when the geared motor 41.41 is driven, the transmission chains 41a, 41a, 41b, 41b, 41G, 41
Since the pinions 43, 43... are simultaneously driven through G, the racks 44b, 44b are driven by the pinions 43, 4
The moving body 44.44 meshing with the rack 44b,
44b and pinions 43, 43, . . . , and can be moved horizontally by a rack and pinion mechanism including pinions 44b and pinions 43, 43, . Therefore, the pallet P supported by the movable bodies 44, 44 and the automobile C loaded on its upper surface can also be moved as they are.

Since the length of the moving bodies 44.44 is longer than the distance between the axes of the pinions 43.43 along the guide rails 42.42, the moving bodies 44.44 are driven simultaneously. The pallet P, which is always driven by at least one of the pinions 43, 43, . The vehicle C can move smoothly between the storage racks 30 and 30 within the distance d of 35.

In this way, the automobile C that has been moved from the storage rack 30 on the side having the lift device 10 to another storage rack 30 provided in parallel thereto is
Using the stacker crane 20 attached to the vehicle, the vehicle can be transported and stored in any vehicle storage space 35 in the storage rank 30.

When transporting a car C stored in any of the car storage spaces 35 in the storage rank 30 on the side where the lift device 10 is provided, first, after lowering the lift device 10 to the delivery position TR, The stacker crane 20 attached to this storage rank 30 stores the pallet P placed on the lift device 10 in the vacant car storage space 35. After that, the stacker crane 20 is moved to the front position of the car storage space 35 where the car C to be taken out is stored, and the car C is taken out while still being loaded on the pallet P, and the car C is moved to the lower delivery position R as necessary. After being transported to the position of the lift device 10, it is placed on the lift device 10, and the lift device 10 is returned to the home position HP. After that, the driver gets on board,
If the vehicle C is started in the reverse direction, the vehicle can be completely removed from the entrance EX.

When the automobile C to be carried out is stored in the storage rack 30 on the side where the lift device 10 is not provided, the horizontal transfer device 40 for the pallet P is used. That is, by reversing the procedure for transporting the car C, first, use the stacker crane 20 attached to the storage rack 30 on the side where the car C is stored to horizontally move the car C loaded on the pallet P. It is transferred to the car storage space 35 where the transfer device 40 is provided, and then the horizontal transfer device 40 is driven to move it to the car storage space 35 on the side where the lift device 10 is provided. However, it is only necessary to transfer this to the lift device 10 using the stacker crane 20 and then transport it to the ground surface by the lift device 10.

By repeating the above steps, the storage rack 30.
The automobiles C, C, . . . can be stored in all of the automobile storage spaces 35, 35, . It goes without saying that the order of loading and unloading the cars C1C... may be different, but in this case, the stacker crane 20.20 and the horizontal transfer device 40 of the pallet P In order to create an empty space for storing the car C as close as possible to the lift device 10, or to prevent empty pallets P from being excessively accumulated in the storage rack 30 on the side of the lift device 10, etc. Therefore, it is assumed that the pallet P is moved at any time with or without the automobile C loaded thereon, and the control of the entire system is realized by program control by a computer (not shown).

Note that the horizontal transfer device 40 for the pallet P has three pinions 43, 43, . . . corresponding to one guide rail 42.
Instead of providing 21, or 4 or more, it is also possible.

That is, a set of car storage spaces 35, 35 which are adjacent to each other and are connected by the horizontal transfer device 40.
Since the gap d is shorter than the length of the movable body 44, which is slightly longer than the full width of the pallet P, the rack 44b of the movable body 44
However, if the pinions 43.43 installed in both moving vehicle storage spaces 35.35 can be engaged simultaneously, the intermediate pinion 43 can be omitted. On the other hand, if the gap d is large and it is not possible to always achieve a meshing state between at least one pinion 43 and the rack 44b by simply disposing one pinion 43 in the middle, the gap d Two or more pinions 43 can be provided within. However, at this time, all pinions 43
．． 43... shall be driven simultaneously.

Another embodiment of the horizontal transfer device 40 for pallets P includes guide rails 42.4.
2 is formed into a groove shape, and the movable body 44.44 has running wheels 44d, 44d... and a guide wheel 44f on the lower surface.
, 44f (FIGS. 7 to 9). The moving body 44 at this time is a square pipe 44
h as the main member (Fig. 8), supports the pallet P by its upper surface, and supports the running wheels 44d, 44d.
are pivoted as double wheels below the square pipe 44i1 via brackets 44e, 44e in order to support the weight of the automobile C loaded on the pallet P. On the other hand, the guide wheel 44. f is pivoted parallel to the lower surface of the square pipe 44h with a shaft 44CI. Moreover, the moving body 44 has endless chains 41d and 4 running on both sides thereof.
1d via connecting pieces 41e, 41e..., and the chains 41d, 41d... are driven by one geared motor 41 via a transmission chain 41f1 rotating shaft 41C]. Figure 7,
(FIG. 9), these series of members constitute a chain drive mechanism as a drive mechanism for the movable body 44, 44 in place of the rack and pinion mechanism in the previous embodiment.

With such a configuration, the moving body 44 has running wheels 4.
4d, 44d, etc., and the sliding plate 42C142c is not used, so that the smoothness of the movement can be maintained over a long period of time.

In addition, in the above explanation, the parking space S was explained as being completely underground, constructed below the ground level G. Depending on the relationship, this can be a semi-underground type with a part of it located above the ground level GL, or even an above-ground type with all of it installed above the ground level GL. . When the above-ground type is used, the lift device 10 is not necessary, so it is sufficient that the stacker crane 20 directly carries out loading and unloading to and from the home position HP at the ground level GL.

In any of these cases, by disposing a turntable in front of the entrance EX, it is possible to change the direction of the automobile C that has been carried out.

In addition, although one set of horizontal transfer devices 40 connecting the storage ranks 30 and 30 is installed at the location closest to the lift device 10, this device may be installed at any other location. Not only can you get them, but you can also install two or more sets. When two or more sets of horizontal transfer devices 40 are installed, the car storage spaces 35, 35 on both sides are used as relay spaces for the movement of cars C, so the overall number of effective parking spaces decreases ( Although,
Since there are a plurality of routes for moving the automobile C between the storage racks 30 and 30, it is possible to shorten the time required for loading and unloading the automobile C.

Furthermore, the storage racks 30 can be installed in any number of two or more sets depending on the required number of parking spaces. At this time as well, it goes without saying that the adjacent storage racks 30, 30 are connected by one or more arbitrary number of horizontal transfer devices 4Q.

As described in detail, according to the present invention, two or more sets of storage racks formed in two rows with a plurality of stacked car storage spaces facing each other are arranged in parallel, and each storage rack is arranged in parallel. A stacker crane equipped with a telescoping fork device is installed in the center of each rack, while a horizontal stacker crane for pallets is installed between at least one set of adjacent car storage spaces facing away from each other in each storage rack. By connecting via a transfer device, pallets and
In addition, since cars loaded on pallets can be freely moved between each other, it is possible to easily build a parking structure with any number of parking spaces by increasing the number of storage racks installed as needed. It has the extremely excellent effect of being able to

In addition, since storage racks and stacker cranes are constructed within the parking lot space, there is no need to provide incidental spaces such as slopes or passageways for automobiles, so land use efficiency can be increased. Another advantage is that the advantages of the prior art can be maintained as they are.
