Description

The present invention relates to a three-dimensional mechanical parking system. That is, the present invention relates to a mechanical parking apparatus having a plurality of pallets on which vehicles are placed, the pallets being arranged in a plurality of stages.

A mechanical parking system is known as a system for effectively using a limited land area to park a larger number of vehicles.
A mechanical parking device is a device for three-dimensionally parking a vehicle such as an automobile. A typical mechanical parking device has a pallet on which a vehicle is placed and an elevating device that moves the pallet up and down.
In addition, in the mechanical parking system, a specific floor is the entry/exit floor.
If the pallet is on the loading/unloading floor, the vehicle is loaded/unloaded while the pallet is left at that position. If the pallet is on another floor, the pallet is moved up and down to the loading/unloading floor, and the vehicle is put in and taken out of the pallet.

A so-called puzzle-type multilevel parking system has a function of not only moving the pallet up and down, but also moving the pallet laterally.
Multilevel parking systems are disclosed in Patent Documents 1, 2, and 3, for example.

Generally, the pallet 100 is rectangular in plan view as shown in FIG. 9(a) and has a concave cross-sectional shape as shown in FIG. 9(b). That is, the pallet 100 has a placing portion 2 on which a vehicle is placed in the center in the width direction, and rising portions 8a and 8b on both sides thereof.
The rising portions 8a and 8b generally consist of vertical wall portions 5a and 5b bent at an angle close to the vertical from the mounting portion 2, and horizontal portions 6a and 6b extending substantially horizontally from the ends of the vertical wall portions 5a and 5b. It is
In the mechanical parking system, the above-described pallets 100 are installed in a plurality of stages in the vertical direction. In many mechanical parking systems, the pallets 100 are also arranged in the horizontal direction, for example, the pallets 100 are arranged in rows and columns as shown in FIG.

As described above, the conventional mechanical parking device incorporates a plurality of pallets 100, and all the pallets 100 to be incorporated have the same shape.
That is, all the pallets 100 have the same overall width L of the pallet 100, the width A of the placing portion 2, the width B of the horizontal portions 6a and 6b, and the height H of the rising portions 8a and 8b.

Japanese Patent No. 3189078 JP-A-7-42388 JP-A-9-137619

When the vehicle is parked in the mechanical parking system, the user gets in the vehicle and drives the vehicle to put the vehicle on the pallet 100 . After that, the user gets out of the vehicle and walks on the pallet 100 to move out of the mechanical parking device. In many cases, the user walks on the horizontal portions 6a, 6b of the pallet 100 as shown in FIG.
When the vehicle is to be pulled out of the mechanical parking device, the user walks on the horizontal portions 6a and 6b of the pallet 100, gets on the vehicle, and starts the vehicle.
Here, the horizontal portions 6a and 6b of the pallet 100 may be wet with water. Since the pallet 100 is generally made of steel plate, it is slippery and dangerous when wet.

There is more than one reason why the horizontal portions 6a and 6b of the pallet 100 get wet.
The inventors discovered one of the causes of the wetness of the horizontal portions 6a and 6b of the pallet 100. FIG.
That is, as shown in FIG. 10, water droplets 102 are generated on the ceiling side (back surface 101 of the upper pallet 100B), and the water droplets 102 fall from the ceiling side and wet the horizontal portions 6a and 6b of the pallet 100A.
Note that there is more than one cause for the formation of water droplets on the rear surface 101 of the upper pallet 100B. One possible cause is that rainwater accumulates on the hood of the automobile, the rainwater evaporates due to the heat of the hood, and is cooled and liquefied on the back surface 101 of the upper pallet 100B to form water droplets 102. be done.
In addition, it is conceivable that rainwater may come around.

SUMMARY OF THE INVENTION An object of the present invention is to develop a mechanical parking device that can eliminate one of the causes of wetness of the horizontal portion of a pallet, paying attention to the above-described problems of the prior art.

A mode for solving the above-described problems has a plurality of pallets on which vehicles are placed, the pallets are installed in at least two stages above and below, and has a moving means for moving the pallets. In a mechanical parking device for moving a pallet to a specific floor for loading and unloading a vehicle, the pallet includes a standard pallet and an odd-shaped pallet, and both the standard pallet and the odd-shaped pallet are placed in the center of the vehicle. and a rising portion rising from the placing portion on at least one side in the width direction. and the odd-shaped pallet may be arranged directly above the reference pallet.

The terms "standard" and "variant" are merely terms for distinguishing between the two types of palettes, and do not imply that the "standard" palette is numerous.
In the mechanical parking device of this aspect, the upper and lower pallets have different shapes. In the mechanical parking device of this aspect, the lower pallet (hereinafter referred to as lower pallet) is a reference pallet. The pallet just above it (hereinafter referred to as the upper pallet) is a pallet with a different shape, and the rising position of the rising portion is closer to the center in the width direction than the lower standard pallet. Therefore, the water droplets that adhere to the upper pallet, move along the upper pallet, and fall down fall onto the mounting portion of the lower pallet and are less likely to wet the rising portion.
This will be explained below.
When the pallet is viewed from the upper surface side, the center placement portion is recessed. On the other hand, when the pallet is viewed from below, it can be said that the center placing portion protrudes downward and the rising portion is recessed.
The back surface of the upper pallet serves as the ceiling surface for the space in which the lower pallet is installed. Here, looking at the upper pallet from the lower pallet side, the center mounting part occupies most of the ceiling surface area, and the rising parts on both sides rise upward from the edge of the mounting part. there is
Water droplets adhere to the rear surface of the mounting portion of the upper pallet, which is the ceiling. The upper pallet is designed to be horizontal in the width direction, but actually tilts slightly in either direction.
Therefore, water droplets adhering to the rear surface of the mounting portion move along the rear surface of the mounting portion toward one side.
However, since the rising portion rises upward as described above, the water droplets stop at the side portion of the rear surface of the mounting portion. Then, the water droplet gradually grows and eventually falls from the edge of the mounting portion.
Here, the rising position of the rising portion of the upper pallet is closer to the center in the width direction than that of the lower pallet. Therefore, the position directly below the edge of the mounting portion of the upper side pallet is the mounting portion of the lower side pallet, and the water droplets fall on the mounting portion of the lower side pallet.

In the above aspect, there is a combination of pallets in which the pallets are arranged side by side on a specific floor, and a combination of pallets in which the pallets are arranged side by side in the horizontal direction also exists on the floor directly above. All of the pallets that make up the combination on the specific floor are reference pallets, and the reference pallets that make up the combination have at least the rising portion on the adjacent side, and the combination on the floor directly above is It is desirable that all of the constituting pallets are irregular-shaped pallets, and that the irregular-shaped pallets constituting the combination also have the rising portion at least on the adjacent side.

In the above aspect, the pallets are arranged in a plurality of stages in the vertical direction and in a plurality of rows in the horizontal direction, and the moving means includes an elevating means for moving the pallets up and down and a traversing means for horizontally moving the pallets. A pallet on the entry/exit floor can move horizontally, and a pallet on a higher floor can move horizontally and/or move up and down. In this case, the vehicle is loaded and unloaded with the pallet placed on the loading/unloading floor, and if the vehicle is loaded/unloaded from the pallet on the floor above, the pallet is moved to the loading/unloading floor. It is desirable that the pallet on the entry/exit floor is a standard pallet, and the pallet on the floor just above that is an odd-shaped pallet.

This aspect employs the present invention in a puzzle-type mechanical parking device.

In the above-described aspect, the pallets are arranged in two stages vertically and in a plurality of horizontal rows, and a pallet storage space is provided below the pallets. , and it is desirable that the upper pallet is an odd-shaped pallet.

In this aspect, the present invention is applied to a two-stage pit type mechanical parking system.

There is an incoming/outgoing floor, a pallet normally on the incoming/outgoing floor and a pallet always on the floor directly above the incoming/outgoing floor, the pallet on the incoming/outgoing floor is a reference pallet, and It is desirable that the pallets on the second floor are odd-shaped pallets.

Here, "always on the above-mentioned loading/unloading floor" means the case where it is always located on the loading/unloading floor and never moves to another floor, and the case where it is basically on the loading/unloading floor but is on another floor as necessary. It is a concept that includes both the case of moving to the floor.
Since the user takes the vehicle in and out on the loading/unloading floor, there are many opportunities for people to walk when it is "always on the loading/unloading floor." Conversely, people rarely walk on pallets on other floors.
In the mechanical parking device of this aspect, the pallets "always on the entry/exit floor" which people often walk on are less likely to get wet with water.

The mechanical parking device of the present invention is highly safe because the horizontal portion of the pallet is less likely to get wet.

Embodiments of the present invention will be further described below.
Prior to describing the characteristic configuration of the present invention, the outline and basic operation of the mechanical parking system 1 to which the present invention is applied will be briefly described.
The mechanical parking system 1 of this embodiment is a mechanical parking system 1 having a four-story structure. As shown in FIG. 2, the mechanical parking device 1 has four vehicle installation areas A, B, C, and D on each floor.
The mechanical parking device 1 is also called a puzzle-type multi-storey parking device, and has pallets 10 and 11 on which vehicles are placed on each floor. As will be described later, the mechanical parking device 1 has two types of pallets 10 and 11. As shown in FIG.
Here, the numbers of pallets 10 and 11 are not uniform, and pallets 10 are provided in all vehicle installation areas A, B, C, and D on the fourth floor, which is the top floor.
On the other hand, the number of pallets 10 and 11 installed on the lower floors (3rd floor, 2nd floor, 1st floor) below the 4th floor is smaller than the number of vehicle installation areas. That is, in the mechanical parking device 1 shown in FIG. 2, three pallets 10 and 11 are installed on each of the lower floors (3rd floor, 2nd floor, and 1st floor).

Vehicle installation areas A, B, C, and D on the fourth floor, which is the top floor, are provided with lifting means (not shown) for moving the pallets 10 up and down.
On the other hand, the vehicle installation areas A, B, C, and D on the lower floors (3rd, 2nd, and 1st floors) are provided with lifting means (not shown) for moving the pallets 10 and 11 up and down, pallets 10 and 11 traversing means (not shown) for traversing the

Next, the operation of the mechanical parking device 1 will be described. For convenience of explanation, vehicle installation areas A, B, C, and D on each floor are denoted as 4-A and 3-B. Vehicle installation area 4-A indicates the vehicle installation area A on the fourth floor, and 3-B indicates the vehicle installation area B on the third floor.
For example, as shown in FIG. 4A, vehicles are installed on all pallets 10 and 11 on each floor, and the vehicle in the vehicle installation area 4-B is desired to leave the vehicle installation area 4-B. It is assumed that vehicles are present in vehicle installation areas 3-B, 2-B, and 1-B directly below -B. In FIG. 4(a), there are no pallets 10, 11 in the vehicle installation areas 3-C, 2-C, 1-C.

In the case as described above, the traversing means of the lower floors (3rd floor, 2nd floor, 1st floor) are driven, and the pallets 10 of the lower floors (3rd floor, 2nd floor, 1st floor) are driven as shown in FIG. , 11 to the side. More specifically, the pallets 10 and 11 in the vehicle installation areas 3-B, 2-B, and 1-B are moved rightward in the drawing, and the pallets in the vehicle installation areas 3-B, 2-B, and 1-B are moved. 10 and 11 are moved to the vehicle installation areas 3-C, 2-C, and 1-C to make the vehicle installation areas 3-B, 2-B, and 1-B empty. In this way, the area below the vehicle area (B) on the floor (fourth floor) to be left is all vacant.
In this state, the lifting means for the vehicle installation area 4-B is driven to lower the pallet 10 in the vehicle installation area 4-B to the first floor. Then, the vehicle is started to leave the mechanical parking device 1. - 特許庁

In the mechanical parking device 1 of this embodiment, the pallet 10 arranged on the first floor is always on the first floor (entry/exit floor).
Also, the pallet 11 arranged on the second floor is normally on the second floor, and is moved to the first floor only when a vehicle is to enter/exit from the pallet 11 arranged on the second floor.
The pallets 10 arranged on the 3rd and 4th floors are always on those floors, and are moved to the 1st floor only when a vehicle is to be entered/exited from the pallet 10.例文帳に追加
Therefore, in the mechanical parking device 1 of the present embodiment, the pallet 10 on the first floor is always on the entrance/exit floor, and the pallet 11 on the second floor is located directly above it.

Next, a characteristic configuration of the mechanical parking system 1 of this embodiment will be described.
There are two types of pallets 10 and 11 employed in the mechanical parking device 1 of this embodiment: a standard pallet 10 as shown in FIG.
As shown in FIG. 5(b), the shape of the reference pallet 10 is the same as that of the conventional one, and has a total width L, a width A of the mounting portion 2, a width B of the horizontal portions 6a and 6b, and a height of the rising portions 8a and 8b. is H.

On the other hand, in the odd-shaped pallet 11, the rising positions 7a and 7b of the rising portions 8a and 8b are closer to the center in the width direction than in the standard pallet 10. As shown in FIG.
That is, as shown in FIG. 5( a ), in the odd-shaped pallet 11 , the boundaries between the rising portions 8 a and 8 b and the placement portion 2 are closer to the center in the width direction than in the standard pallet 10 .
More specifically, as described above, the rising portions 8a and 8b have the vertical wall portions 5a and 5b and the horizontal portions 6a and 6b. is closer to the center in the width direction than the reference pallet 10 .

That is, the full width LA of the odd-shaped pallet 11 is equal to the full width L of the standard pallet 10 . The width a of the placement portion 2 of the odd-shaped pallet 11 is narrower than the width A of the placement portion 2 of the standard pallet 10 . The width b of the horizontal portions 6 a and 6 b of the irregular-shaped pallet 11 is wider than the width B of the horizontal portions 6 a and 6 b of the standard pallet 10 . The height h of the raised portions 8a and 8b of the odd-shaped pallet 11 is equal to the height H of the raised portions 8a and 8b of the standard pallet 10. FIG.

Therefore, there is the following relationship between the two sizes.
LA=L
a<A
b>B
h=H

In the mechanical parking device 1 of the present embodiment, all the pallets arranged on the first floor, which is the loading/unloading floor, are the standard pallets 10, and all the pallets arranged on the second floor, which is the floor just above, are the odd-shaped pallets 11. .
Pallets on other floors are all reference pallets 10 .
In the mechanical parking device 1, three pallets 10 are installed on the first floor. Therefore, on the first floor, there is a combination of pallets in which the pallets 10 are arranged side by side.
That is, if the state of FIG. 2 is used as a reference, there is one combination of pallets arranged side by side in the horizontal direction by the pallets 10 in the vehicle installation areas 1-A and 1-B.
Since the pallets 10 installed on the first floor move laterally, the pallets 10 in the vehicle installation areas 1-B and 1-C constitute a combination of pallets arranged in a lateral direction depending on the position after the movement. may be Similarly, the pallets 10 in the vehicle installation areas 1-C and 1-D may constitute a combination of pallets arranged side by side in the horizontal direction.

On the other hand, there is also a combination of pallets 11 in which the pallets 11 are arranged side by side on the second floor directly above. The pallets 11 on the second floor also move in the lateral direction, but if the state of FIG. There is one set of combinations.
Since the pallets 11 installed on the second floor move in the lateral direction, the pallets 11 in the vehicle installation areas 2-B and 2-C constitute a combination of pallets arranged in the lateral direction depending on the position after the movement. may be Similarly, the pallets 11 in the vehicle installation areas 2-C and 2-D may constitute a combination of pallets arranged side by side in the horizontal direction.

Also in the mechanical parking device 1 of this embodiment, as shown in FIG. 3, water droplets 15 adhere to the ceiling side of the first floor (the back surface 12 of the upper pallet 11).
However, in the mechanical parking apparatus 1 of this embodiment, the pallet 10 installed on the loading/unloading floor (first floor) differs in shape from the pallet 11 on the second floor constituting the ceiling of the first floor. In the mechanical parking device 1 of this embodiment, the pallet 10 on the first floor is the reference pallet 10 . The pallet 11 on the second floor just above is an odd-shaped pallet 11, and the rising positions 7a and 7b of the rising portions 8a and 8b are closer to the center in the width direction than the pallet 10 below. Therefore, the water droplets 15 adhering to the pallet 11 on the second floor, moving along the pallet 11 on the second floor, and falling downward fall on the mounting portion 2 of the pallet 10 on the lower (first floor), rising portion 8a, It is difficult to wet 8b.

For example, for the space of the vehicle installation area 1-A on the first floor, the back surface 12 of the pallet 11 in the vehicle installation area 2-A on the second floor is the ceiling surface. When looking at the upper (second floor) pallet 11 from the lower (first floor) pallet 10 side, the central placement portion 2 occupies most of the ceiling surface area, and the rising portions 8a on both sides thereof, 8b rises upward from the edge of the mounting portion 2. As shown in FIG.

The water droplets 15 adhere to the rear surface 12 of the mounting portion 2 of the pallet 11 on the second floor, which is the ceiling. The upper pallet 11 on the second floor is designed to be horizontal in the width direction, but is actually slightly inclined in one direction.
Therefore, the water droplets 15 adhering to the rear surface 12 of the mounting portion 2 move along the rear surface 12 of the mounting portion 2 to one side.

However, since the rising portions 8a and 8b of the pallet 11 on the second floor rise upward as described above, the water droplets 15 stop on the side portions of the placing portion 2. FIG. Then, the water droplet 15 gradually grows and finally falls from the edge of the placing portion 2 of the pallet 11 on the second floor.
Here, the pallet 11 on the second floor is an odd-shaped pallet 11, and the rising positions 7a and 7b of the rising portions 8a and 8b are closer to the center in the width direction than the pallet 10 on the first floor. Therefore, the position immediately below the edge of the pallet 11 on the second floor is the pallet 10 on the first floor, and water droplets are deposited on the pallet 10 on the first floor as shown in FIG. drop down.
Therefore, water droplets do not fall on the horizontal portions 6a and 6b of the pallet 10 on the first floor, and the horizontal portions 6a and 6b do not get wet. Therefore, it is non-slip and highly safe.

Although the mechanical parking system 1 of the embodiment described above is a puzzle-type three-dimensional parking system, the present invention can also be applied to other types of mechanical parking systems.
For example, the present invention can also be applied to a two-stage pit-type multilevel parking system.
FIG. 6 shows a mechanical parking device 50 according to another embodiment of the present invention, which is a two-stage pit-type three-dimensional parking device.
The mechanical parking device 50 of this embodiment has a structure of two floors above ground and one floor below ground. In the mechanical parking device 50, there are vehicle installation areas A, B, and C on the first floor and the second floor as shown in FIG.
Pallets 10 and 11 on which vehicles are placed are provided on the first and second floors. The basement is a pallet storage space 51 having a volume capable of accommodating vehicles.

The mechanical parking device 50 is provided with lifting means for moving the pallets 10 and 11 up and down.
In the mechanical parking device 50, the pallets 10 and 11 are normally located on the first floor and the second floor. A pallet 10 installed on the first floor is a reference pallet 10 . The pallets 11 installed on the second floor are odd-shaped pallets 11 .
When a vehicle is taken in and out of the pallet 10 installed on the first floor, it is carried out without moving the pallets 10 and 11 as shown in FIG. 7(a).
When the vehicle is taken in and out from the pallet 11 installed on the second floor, the pallets 10 and 11 in the column are lowered, and the pallet 10 on the first floor is moved to the underground pallet as shown in FIG. 7(b). It is lowered to the storage space 51, and the pallet 11 installed on the second floor is lowered to the loading/unloading floor on the first floor. Then, the vehicle is taken in and out from the pallet 11 lowered to the first floor.

Also in the mechanical parking device 50 of this embodiment, water droplets do not fall on the horizontal portions 6a and 6b of the pallet 10 on the first floor, and the horizontal portions 6a and 6b do not get wet.

In each of the embodiments described above, the pallets 10 and 11 are arranged in two or more horizontal rows, and there is a combination of two adjacent pallets 10 and 11 in a specific stage. The reference pallet 10 that makes up the combination has risers 8a, 8b on both sides. Similarly, the odd-shaped pallet 11 forming a combination also has raised portions 8a and 8b on both sides.
Therefore, at the matching portions of the two pallets 10 and 11 on the same floor, the horizontal portions 6a and 6b of the pallet 10 are connected to form a wide sidewalk as a whole.
However, the present invention is not limited to this configuration, and the pallets 10 and 11 may simply be arranged vertically (in the height direction) in a row instead of being arranged in the horizontal direction. That is, in the mechanical parking apparatus 1, 50, the pallets 10, 11 are arranged in rows and columns in the horizontal direction and the vertical direction when viewed from the front, but the present invention is not limited to this configuration. may be arranged only.

The shapes of the pallets 10 and 11 described above are only schematic representations of the shapes of the standard pallets 10 and 11, and actual pallets have irregularities, cutouts, and the like in various portions.
In some cases, the vertical wall portions 5a and 5b of the rising portions 8a and 8b are inclined.

According to the mechanical parking device 1, 50 described above, water droplets are less likely to fall on the horizontal portions 6a, 6b of the pallet 10 on the loading/unloading floor, and the horizontal portions 6a, 6b are less likely to get wet. As described above, the user often walks on the horizontal parts 6a, 6b of the pallet 10 on the entry/exit floor. is less likely to get wet, so there is little concern that the user will slip.
As a side effect of the embodiment, the ceiling height of the walking area can be increased.
As described above, the user often walks on the horizontal portions 6a and 6b of the pallet 10 on the loading/unloading floor, but may walk on the placement portion 2 when the vehicle that has entered the warehouse is small.
In this case, since most of the loading section 2 is occupied by the vehicles that have entered, the user walks along the boundaries between the vertical walls 5a and 5b and the loading section 2 as shown in FIG.

Here, in the mechanical parking apparatus 1, 50 of the above-described embodiments, the horizontal portions 6a, 6b of the pallet 11 above the pallet 10 on the loading/unloading floor are wider. Therefore, when viewed from the loading/unloading floor side, the width of the concave portion (the concave portion formed by the rising portions 8a and 8b) on the second floor is wide, and the ceiling height of the space above the user's head is high.
Therefore, even if a tall person walks along the boundary between the vertical walls 5a and 5b and the placement section 2 as shown in FIG. 8, the risk of hitting the head against the ceiling is low.
