Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of use] The present invention relates to a multi-story parking lot that does not use a pallet for storing vehicles. In particular, the present invention relates to a multi-storey parking lot suitable for storage of vehicles by automobile manufacturers, storage of vehicles at distribution centers and the like.

In the present invention, the entry / exit port refers to at least one of the entry / exit port, and is generally a place where a driver gets on and off. The same applies to "in / out". The "transfer port" is a port through which a transfer device in a shelf group including a large number of shelves transfers a vehicle to and from the outside of the shelf group.

[Conventional technology]

An example of a three-dimensional parking lot using a stacker crane is disclosed in Japanese Patent Application Laid-Open No. 61-38071. This one is
A large number of shelves are provided along the traveling path of the stacker crane, and an entrance, an exit, a pallet magazine, and a conveyor line are provided at one end thereof.

Upon warehousing, one pallet is supplied from the pallet magazine to the warehousing entrance via the conveyor. When a vehicle is placed on this pallet, it is conveyed by a conveyor to a transfer port with a stacker crane. The stacker crane stores this on-board pallet on a shelf. When there are no more pallets in the pallet magazine, stacker pallets are supplied from the shelves by stacker cranes.

When a shipping instruction is issued, the in-vehicle pallets on the shelves are transported to the transfer port by the stacker crane and then delivered to the shipping port by the conveyor. The empty pallets left at the delivery port are collected by the conveyor in the pallet magazine. When a predetermined number of pallets are accumulated in the pallet magazine, they are stored on shelves by the conveyor and stacker crane.

Japanese Utility Model Laid-Open No. 58-82981 discloses that a carriage is used instead of a conveyor as a means for transporting an in-vehicle pallet between a loading / unloading port and a transfer port. However, the relationship with stacker cranes and pallet magazines is not shown.

Japanese Patent Laid-Open No. 51-34623 discloses a system that does not use a pallet for storing a vehicle. This product uses shelves, a horizontal moving platform for stacker cranes, and a fork-type receiving platform for loading and unloading ports. The wheels of the vehicle are mounted on this fork type pedestal. The fork type pedestal is a plate in which plate members are arranged in a horizontal direction at predetermined intervals. The fork type cradle of the stacker crane is installed so that it can pass horizontally and vertically with respect to the fork type cradle of the shelf and the loading / unloading port.

When the wheels of the vehicle are placed on the fork-shaped cradle at the loading entrance during loading, the fork-shaped pedestal of the horizontal moving platform of the stacker crane is lifted from below the fork-shaped pedestal of the loading dock, and the fork-shaped platform of the stacker crane is loaded. Scoop up the wheels of the vehicle on the cradle. On the shelf, the wheels of the vehicle are placed on the fork-type cradle of the vehicle by lowering the fork-type cradle of the stacker crane from above.

The warehousing is the reverse of the above operation.

Incidentally, in a factory, a monorail car is often used as a means for transferring a load in order to effectively use the space three-dimensionally. This monorail car is suspended. That is, the traveling body of the monorail car is suspended from the rail in the air, and the load is suspended on the lower surface of the traveling body. At the position to unload the load from the monorail car to the equipment on the ground and the position to transfer the load from the equipment on the ground to the monorail car,
The rail on which the monorail car is placed can be moved up and down. The monorail car includes a self-propelled type equipped with a motor and a type in which the monorail car travels by engaging with a chain stretched above the rail. This monorail car is often used in the automobile industry, and for example, there is one that hangs the body of a vehicle and conveys it. The body is transported by supporting the lower surface of the body (for example, a jack amp point of the vehicle). (Special public relations
(Problems to be solved by the invention) When a pallet is used to store vehicles, a number of pallets equal to the number of stored vehicles is required, and a large number of vehicles are required. However, there is a problem in manufacturing the pallet and cost. Further, since it is necessary to interrupt the loading / unloading operation of the vehicle and to supply and recover the pallets, it takes time to load / unload the vehicle.

Since the pallet is not used in the fork type cradle system, the above problems do not occur. However, it is necessary to provide a fork type cradle on every shelf, which is expensive. In particular, since the fork-type cradle of the stacker crane passes between the fork-type cradle, it is necessary to manufacture the plate materials forming the fork-type cradle of the shelf with high precision. It becomes a problem as the number of vehicles stored increases.

An object of the present invention is to provide an inexpensive multi-story car park in a system using a fork type cradle.

[Means for solving problems]

The above-mentioned object is not to provide a fork-type cradle on the shelf, but only to provide a cradle for receiving the wheels of the vehicle, and to use the trolley to transport the vehicle between the loading / unloading port and the transfer port. Alternatively, it can be achieved by using a fork-type cradle for at least one of the transfer port and the carriage, and providing the carrier so as to support the jack-up point on the lower surface of the body.

[Action]

A pallet is not required between the loading / unloading port and the loading / unloading port because a trolley having a fork type pedestal is used to transfer the pallet. The transfer device for transferring between the transfer port and the shelf supports the jack-up point of the vehicle without supporting the wheels of the vehicle, so that the pallet and the fork type pedestal can be eliminated.

〔Example〕

The present invention will be described below with reference to an embodiment shown in FIGS. This embodiment is for storing a vehicle of an automobile manufacturer.

First, the overall configuration will be described with reference to FIG.

1 is a stacker crane as a known transfer device,
It runs between the shelves 5 and 6 on both sides. The shelf group 5 and 6 is composed of a large number of shelves. Here, stacker crane 1 and shelves on both sides of it
7 sets are arranged side by side with 5 and 6 as a set of 3D warehouse.

On the first row of shelves at one end of each shelf group 5, there is a transfer port for receiving.
10 are provided. A transfer port 11 for delivery is provided on the first row of shelves at the one end of each shelf group 6.

A warehousing port 13 is provided in front of the transfer port 10 for warehousing. The warehousing entrance 13 and the transfer entrance 10 are connected by a dolly 15 for warehousing which runs on a rail 14.

A delivery port 17 is provided in front of the transfer port 11 for delivery. The warehousing port 13 is provided laterally between the unloading port 17 and the transfer port 11. The delivery port 17 and the transfer port 11 are connected by a delivery cart 19 that travels on a rail 18. When the vehicle exits the exit port 17, the driver gets on and runs toward the exit route 21.
A driver can run around the exit port 17.
In addition, the circumference of the delivery port 17 is surrounded by a shelf (not shown) that can be opened and closed for safety.

The transfer ports 10, 11, the loading port 13, and the loading port 17 are provided with fork-type pedestals as described later.

Numerals 23 and 24 are entrances of the multi-storey parking lot, and are installed outside the width range formed by the seven groups in the direction in which the group consisting of the stacker crane 1 and the rack groups 5 and 6 is arranged in parallel. Entrance 23,24
Are provided on the sides of the entrance 13 and the exit 17. Approach 25,26
The vehicle that has moved forward stops at the entrances 23 and 24, and the driver dismounts. There are recesses (not shown) on the road surface of the entrances 23 and 24 for determining the stop position of the vehicle. This recess is located at the front wheel of the vehicle and the front wheel enters the recess. Instead of a recess,
You may provide a convex part in the front-back position of a front wheel. Entrance 23,24
For safety, it is surrounded by a shelf (not shown) that can be opened and closed. Two entrances 23 and 24 are provided.

The vehicles at the entrances 23 and 24 are conveyed to the respective entrances 13 by a cart traveling overhead, for example, a suspension type monorail car 27. 28
Is the running line of the monorail car 27, and the entrances 23, 24,
Also, the vehicle passes above the respective entrances 13 and returns to the entrances 23 and 24.
The monorail car 27 has a known structure, and as shown in FIG. 10, it comprises a traveling body 27a traveling on the rails of the traveling line 28, a suspender 27b suspended below the traveling body 27a, and a traveling motor 27c.
The suspension 27b supports a jack point of the vehicle and can be opened and closed in the vehicle width direction. Monorail car 27
The means for exchanging vehicles between the vehicle and the entrances 23, 24 and the entrance 13 are publicly known. For example, the rail supporting the monorail car 27 is moved up and down at the transfer position.

Many monorail cars 27 are installed on the traveling line 28, but only one is shown. The monorail car 27 transports the vehicles one by one. Since the vehicle enters the entry ports 23 and 24 in the forward direction, it is placed on the entry port 13 and the shelf facing the exit port 17 side.

28a and 28b are bypass lines. 29 is a line connecting to a production factory or a maintenance factory.

FIG. 9 shows the structure of the shelf. Cradles 35 and 36 for supporting the front and rear wheels of the vehicle are provided on the shelves, respectively. The pedestals 35 and 36 are installed on columns 37 and 38 in front of and behind the vehicle. The front and rear pedestals 35 and 36 are divided into front and rear as shown in the figure, and are not continuous. The pedestal 35 that maintains the front wheels of the vehicle is provided with a recessed seat 35a for preventing wheel removal. The front wheels are located between the front and rear projections of the seat 35a. The cradle 36a of the cradle 36 that supports the rear wheel has a flat plate shape. According to this, the vehicle is stored with the front wheels as a reference. The seat 36a is sized to accommodate changes in the wheel base depending on the vehicle model.

Reference numeral 39 is a horizontal beam that connects the front and rear columns 37 and 38, and is provided at every other stage of the shelf.

1a is a fork provided on the lifting platform of the stacker crane 1. This fork 1a can be moved back and forth toward a shelf like a known one. The fork 1a is installed so as to support the body jack-up point between the front and rear wheels. This is the position to jack up the body when replacing the wheels. A cushioning material such as rubber is provided on the upper surface of the fork 1a to prevent the body from being scratched.

Since there is no member between the front and rear pedestals 35 and 36, the fork 1a can be easily moved back and forth and moved up and down even if the vehicle height between the pedestals 35 and 36 and the lower surface of the body is low.

According to this, although it is necessary to limit the change in the distance between the wheel base and the jack amp point, it is possible to sufficiently park the vehicle by limiting the size and vehicle type of the vehicle.

In FIGS. 2 and 3, the transfer ports 10, 11, the loading port 13, the loading port 17, and the trucks 13, 15 each have a fork-type pedestal. A fork type pedestal that supports the front wheels of the vehicle is indicated as A or a, and a fork type pedestal that supports the rear wheels is indicated as B or b. Since the vehicle is placed on the basis of the fork-type pedestals A and a for the front wheels, the length of the fork-type pedestals B and b for the rear wheels in the traveling direction of the vehicle is less than the length of the fork-type pedestals A and a for the front wheels. Is also long.

The fork type pedestals A and B are installed at the transfer ports 10 and 11, the loading port 13 and the loading port 17. The fork type pedestals a and b are installed on the trucks 15 and 19. That is, A and B show fixed side fork type pedestals, and a and b show movable side fork type pedestals.

The movable side fork type pedestals a and b can move up and down with respect to the fixed side fork type pedestals A and B.

In the fixed-side fork type pedestals A and B, there is a gap between the fork type pedestals in the width direction of the vehicle, and it is large enough to pass the lifts supporting the fork type pedestals a and b of the trucks 15 and 19. It is provided. As a result, the carriages 15 and 19 are transferred to the transfer port 10,1.
It can run up to 1, the entrance 13 and the exit 17.

Fork pedestals A and a for front wheels and fork pedestals for rear wheels
There is no obstruction of the fork type cradle between B and b. In particular,
Since the fork 1a moves up and down at the transfer ports 10 and 11, no obstacle is provided.

At the exit port 17, between the front and rear fork-shaped pedestals A and B, there is provided a footboard 41 through which the rear wheels of the vehicle pass. The front end of the fork-type cradle A for the front wheels is connected to the exit passage 21.

The fork type pedestals A and B are all at the same height.

Fork type pedestals A, B, a, b are shown in Figs.
It will be described with reference to the drawings. The figure shows a state where the carriage 15 is stopped at the transfer port 10 and the vehicle is about to be transferred to the transfer port 10.

37, 37, 38, 38 are columns for constructing the shelves as described above, and the ones shown are the columns for constructing the shelves in the first row. Fixed fork type pedestals A and B are attached to each of these columns.

The fork type pedestals A, B, a, and b are formed by arranging a plurality of fork members (plate members shown in the drawing) at predetermined intervals as shown in the drawing. The outer ends of the fork members of the fixed-side fork type pedestals A and B in the vehicle width direction are fixed to the fixed seat 46. The inner ends of each fork member are not connected. The fixed seat 46 is fixed to the columns 37 and 38. The front and rear fixed seats 46, 46 are not connected. The fork-shaped cradle A and B of the entrance 13 and the exit 17 are fixed to a pillar standing on the ground.

On the other hand, the inner ends of the fork members of the movable side (carriage side) of the fork-shaped pedestals a and b are fixed to the lift table 51. The outer ends of each fork member are not connected. For this reason,
The fork members of the movable side fork type pedestals a and b can move up and down between the fork members of the fixed side fork type pedestals A and B.

When the lift table 51 is raised, the lower surfaces of the fork-shaped pedestals a and b become higher than the upper surfaces of the fixed-side fork-shaped pedestals A and B. Lift 5
When 1 is lowered, the upper surfaces of the fork type pedestals a and b become lower than the lower surfaces of the fixed side fork type pedestals A and B.

The width L ₁ of the lifting platform is smaller than the distance 1 between the inner ends of the fixed-side fork type pedestal. The distance L ₂ between the outer ends in the width direction of the movable side fork type pedestal is smaller than the distance between the columns in the width direction. As a result, the fork-shaped pedestals a and b can be passed through the transfer ports 10 and 11, the loading port 13 and the loading port 17 in a raised or lowered state.

The lifting platform 51 is lifted and lowered by a lifting device provided inside. 52 is a dolly
There are 19 wheels.

In the loading port 13, the transfer ports 10, 11, and the front wheel side fork type pedestals A, a of the trucks 15, 19, the fork members AP, ap at the front and rear ends in the traveling direction of the vehicle are higher than the other fork members. Is projected. This enables positioning with the front wheels as a reference.

At the loading port 13 and the transfer port 10, particularly at the transfer port 10, the fork members A at the front and rear ends of the fixed-side fork type pedestal A are used.
P and AP are located inside the fork members ap and ap at the front and rear ends of the fork type pedestal a on the side of the carriage 13. That is, the distance between the front and rear fork members protruding upward for positioning is smaller on the transfer port 10 side than on the truck 15 side. Therefore, when the vehicle is placed on the transfer port 10, the vehicle is positioned with higher accuracy. Therefore, it is possible to prevent contact with a pillar or the like even when it is stored in a shelf.

In FIG. 8, a fork type pedestal B on the rear wheel side of the exit port 17 is shown.
A stopper 42 for preventing the vehicle from moving backward is provided on the rear end side of the rear end fork member. Stopper 42
Protrudes above the fork type pedestal B. Between the front and rear fork type pedestals A and B, there is a tread 41 for passing rear wheels. The front of the front wheel side fork type pedestal A is connected to the exit passage 21.

The operation of this configuration will be described.

The warehousing operation will be described.

The vehicle entering the vehicle enters the entrance 23, 24 in the forward direction. When the driver dismounts and issues an instruction to store the goods, the monorail car 27 on the upper side lifts the goods and conveys the goods to the specified entrance 13.
The vehicle is placed on the fork type cradle A, B of the storage entrance 13.

The dolly 15 is a storage entrance 1 with the fork-shaped cradle a and b lowered.
Enter 3. When the vehicle is received by raising the fork type pedestals a and b, the dolly 15 enters the transfer port 10 in this state, lowers the fork type pedestals a and b, and travels toward the storage port 13.

The vehicles placed on the fork type pedestals A and B of the transfer port 10 are placed on the rack seats 35a and 36a by the stacker crane 1.

The leaving operation will be described.

When there is an issue command, the stacker crane 1 takes out the vehicle from the shelf and places it on the fork type pedestals A and B of the transfer port 11.

The dolly 19 has a transfer port 1 with the fork-shaped pedestals a and b lowered.
Enter 1. When the vehicle is received by raising the fork type pedestals a and b, the dolly 19 travels toward the exit port 17 in this state.

When the fork type pedestals a and b are lowered at the delivery port 17 and the vehicle is placed on the fork type pedestals A and B of the delivery port 17, the dolly 19 travels toward the transfer port 11 in this state.

Thus, the shelf does not require a fork-type pedestal, and thus can be manufactured at low cost. Also, the entrance 13 and the exit 1
A dolly 1 equipped with a fork type pedestal between 7 and the transfer ports 10 and 11.
Since the vehicle is transported by 5,19, the stacker crane 1 can support the jack-up point. For example, when the vehicle is placed on a pallet, it is practically impossible to support the jack-up point with a stacker crane because the gap between the pallet and the bottom surface of the vehicle is small. From this, the effect can be understood.

Since the entry passage is overhead and the exit passage is on the ground, it is possible to enter and exit at the same time.
That is, the vehicle can be put into the vehicle from the left half of the three-dimensional warehouse group while the vehicle is stored in the right half of the three-dimensional warehouse group of FIG. 1, and it is possible to perform the detailed loading and unloading operations simultaneously. is there. Also, the control is easy.

Since the traveling line 28 does not pass above the exit port 17, it is safe.

Since all the sets of three-dimensional warehouses have outlets, it is possible to directly issue from all the three-dimensional warehouses and to issue a large number of vehicles at one time. This is a configuration that prioritizes unloading rather than warehousing, and is suitable for applications such as storage by automobile manufacturers and transportation centers.

In addition, the exit 17 is the entrance, the entrance 13 is the exit, and the entrances 23, 2
If 4 is the exit, entry will be given priority.

One shelf group 5 is provided with a storage entrance 13, a carriage 15, and a transfer opening 10, and the other shelf group 6 is provided with a transfer opening 11, a carriage 19, a delivery opening 17, etc. It is possible to mix incoming and outgoing in a shelf group.

When the shelf group 5 is not provided with the transfer port, the storage port 13 is provided in the middle of the traveling path of the carriage 19.

The embodiment shown in FIG. 11 will be described. A transfer port 10a is provided on the second row shelf of the shelf group 5, and the first row shelf serves as a passage for the carriage 15.
There is an exit port 17a in front of the shelf group 5, and a trolley 15 is a transfer port 10a.
And the exit 17a, and there is an entrance 13 along the way. Below the traveling line 28, there is an entrance 13a in the passageway of the truck 19.
There is. Fork type pedestals A and B are provided at the transfer port 10a, the storage port 13a, and the output port 17a. The fork type pedestals A and B of the transfer port 10a are at the same height as the fork type pedestals A and B of the transfer port 11. The stacker crane 1 includes two sets of forks 1a and 1b.

When the transfer is performed at the transfer ports 10a and 11, the fork 1a projects to the transfer port 11 and the fork 1b projects to the transfer port 10a. Then, the lift table including the forks 1a and 1b moves up and down in this state. Therefore, it is possible to leave the vehicles at the transfer ports 10a and 11 at the same time and receive the loaded vehicles at the same time.

According to this, since it is possible to leave the two outlets 17 and 17a at the same time, it is possible to perform the leaving in an extremely short time. on the other hand,
It is possible to store two storage ports 13 and 13a in one traveling line 27, and the configuration can be simplified.

A gap 45 is provided between each pair so that the vehicle door can be opened and the passengers can board the vehicle.

Distance between exit port 17 and transfer port 11, exit port 17a and transfer port 10a
The distance between and is as close as possible. Trolley 19,15
The time required for one round trip is the same, which facilitates the transportation of the two vehicles by the stacker crane 1. Therefore, the exit port 17a is provided near the entrance port 13.

When the fork type pedestals A and B are not provided at the transfer ports 10 and 11, the vehicles are transferred between the trucks 15 and 19 and the stacker crane. A fork type pedestal may not be provided on either the transfer port 11 or the delivery port 17, and if it is not provided on the delivery port 17, the vehicle of the dolly 19 is boarded. The tread 41 is on the exit 17 side. In such an embodiment, it takes a longer time to enter and leave the warehouse than in the above embodiments.
