Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] This invention relates to improvements in multi-story parking garages, and more particularly to increasing the speed of movement of vehicles within a parking floor.

[Prior Art] In many conventional multi-story parking lots, vehicles are allowed to move in and out of the parking lot completely on their own. Additionally, some multi-story parking lots are equipped with elevators for transporting vehicles, while other parts rely on vehicles to move in and out of the garage.

All of these multi-story parking garages require a large floor space because of the space for vehicles to move around, and because passengers must enter and exit the parking floor, security equipment such as emergency escape equipment is required on the parking floor. There are problems such as harming the surrounding environment due to the exhaust gas from.

In order to solve these problems, it is of course conceivable to construct a fully automated multi-storey parking lot.

The problem in this case is how to quickly move the vehicle within the parking floor. If vehicles move slowly on the parking floor, there will be delays in the entry and exit of vehicles, and the multi-story parking lot will no longer function properly.

The next problem that follows this one is how to quickly get vehicles into and out of the elevator.

Consider a case where a passenger drives a vehicle into an elevator and stops the vehicle. In this case, it usually takes about 30 to 40 seconds because the vehicle has to stop inside the narrow elevator. Similarly, when passengers board a vehicle accommodated in an elevator and the vehicle departs, three
It takes about 0 to 40 seconds. Since there is a limit to the number of elevators that can be installed in a multi-story parking lot, there is a risk that the processing capacity of the multi-story parking structure will be saturated due to vehicles entering and exiting from the elevators.

[Problem of the Invention] An object of the present invention is to increase the moving speed of vehicles within the parking floor of a multi-story parking lot and to shorten the time required for parking vehicles and floats. Another object of the present invention is to shorten the time required for vehicles to enter and exit the elevator.

[Structure and operation of the invention] The multi-story parking lot of the present invention has an elevator for transporting vehicles to a parking floor, and a parking space for transporting vehicles between the elevator and a parking pallet provided in the parking floor. In a multi-story parking lot equipped with a trolley,
The parking pallet is fixed to the parking floor, and power rollers are provided on the floor surfaces of each of the power truck, the elevator, and the parking pallet to move the vehicle therebetween by sliding motion.

That is, in this invention, the power truck is made to run on rails, and the moving speed of the power truck is increased. Further, power rollers are used to move the vehicle between the elevator and the power truck, or between the power truck and the parking pallet. In this way, the vehicle is moved smoothly.

Preferably, a space for entering and exiting the garage is provided adjacent to the entrance/exit of the elevator, and a floor surface for entering and exiting the garage is provided with a space for moving vehicles between the elevator and the elevator.

A powered roller will be provided for this purpose. In this way, the vehicle can enter the storage station independently of the elevator going up and down, and
Alternatively, it can be started from the warehouse.

Examples are shown below.

[Example] The overall structure of a multi-level parking lot will be explained with reference to FIGS. 1 and 2. In FIG. 1, 2 is a building of a multi-level parking lot, 4 is an entry floor, and 6 is an exit floor.

The warehousing floor 4 and the warehousing floor 6 may not be distinguished, and the same floor may be used for warehousing and warehousing. 8-1 to 8-11 are
A set of an elevator 9 for warehousing and a warehousing base 11 is provided, and one warehousing base 11 is provided for each elevator. 10-
1 to 10-2 are a set of an elevator 9 for leaving the warehouse and an elevator 12 for leaving the warehouse, and similarly, an elevator I2 for leaving the warehouse is provided for each elevator 9.

The warehousing base 11 and the warehousing base 12 are composed of two power rollers provided corresponding to the front wheels and rear wheels of the vehicle. Similarly, the elevator 9 is also provided with two power a-ra for transporting vehicles. That is, the vehicle is moved between the elevator 9 and the warehousing base II and the warehousing station 12 by sliding the vehicle using power rollers. Note that the same elevator may be used for both purposes without distinguishing between the elevator for entering the warehouse and the elevator for leaving the warehouse. Furthermore, the warehousing base 11 and the warehousing base 12 may also be used. Furthermore, two incoming bases 11 and two outgoing units 12 may be provided on both sides of the elevator to increase the throughput of the incoming units 11 and outgoing units 12. Reference numeral 13 denotes a pedestrian floor of the building, which is used for pedestrian passage from the warehousing floor 4 or to the warehousing floor 6, as well as for shopping centers, office spaces, and the like.

FIG. 2 shows a plan view of the parking floor 14. Note that the elevator 9 and exit 12 at the bottom of the figure are for the exit floor 6. In the figure, 16 is a power truck for transporting the vehicle, and 18 is a parking pallet for the vehicle. Two power rollers are also provided on the power truck 16 and the parking pallet 1B, and the sliding motion of the power rollers moves the vehicle to the power truck 16.
and the parking pallet 18. Reference numeral 20 denotes a rail for moving the power truck, and the power truck 16 is connected to the rail 20.
It runs on wheels (not shown) above. and power truck 1
G is assumed to have a motor (not shown), and for example, the motor rotates wheels using electric power from a power line provided separately from the rails 20, so that the G moves on the rails 20.

It is also assumed that the power truck 20 is controlled by receiving a control signal through a signal line (not shown).

FIG. 3 shows a power roller 22 provided on the floor of the elevator 9 and the power truck 16. In addition, in the embodiment, the warehousing base I
Vehicle movement between I and the exit station 12 and the elevator 9, between the elevator 9 and the power truck 16, and between the power truck 16 and the parking pallet 18 are all performed using the power rollers 22. Although not particularly shown, the warehousing group II and the warehousing group! 2
, the parking pallet I8 is also provided with a similar power roller 22. The power roller 22 is a power roller,
Two locations are provided on the floor of the power truck 16 and the elevator 9, corresponding to the front wheels and rear wheels of the vehicle. These powered rollers 2
2 causes the vehicle to skid. 24 is a wheel stopper for fixing the vehicle to the power truck 1G. Reference numeral 26 denotes a sensor such as an ultrasonic wave for detecting movement of the vehicle, which is used to confirm that the movement of the vehicle has started and that it has ended. Here, the power roller 22 is shown as a side-slipping power roller. This is to prevent the vehicle from slipping vertically with respect to the power rollers 22.

Of course, longitudinal sliding power rollers may be used so that the vehicle is moved by the power rollers in the longitudinal direction of the vehicle. Further, instead of providing two power rollers corresponding to the front wheels and rear wheels of the vehicle, a single longitudinal power roller may be used to correspond to both the front wheels and the rear wheels.

28 is a motor for driving the power roller 22, 30 is a motor for making the power truck 16 self-propelled, and 32 is a control circuit for the power truck 16, which is controlled by signals from a central control computer (not shown). In addition, the elevator 9, the parking pallet 18, or the loading station 11 or the loading station! 2 shall also be provided with a similar control circuit.

In addition to this, a power source, a signal line with a computer for central control, and sensors for the position, speed, acceleration, etc. of the truck 16 are used to drive the power truck 16. For these, see Figure 4.
This will be explained with reference to FIG.

FIG. 4 shows the arrangement of the power truck 16 and the parking pallet I8. Each parking pallet! 8 is provided with a power roller 22 similar to that provided in the power truck 1G. Then, the motor 28 rotates the power roller 22 to move the vehicle, and the sensor 2G confirms the movement of the vehicle. It is also assumed that the parking pallet 18 is fixed to the floor 14. These points are based on stock! The same applies to 1 and the delivery base 12.

34 is a power line provided on the floor of the parking floor 14, which is used as a power source for the power truck 16. 3G is a signal line with a central control computer.

FIG. 5 shows a side view of the power truck 16. 40 is a wheel,
It runs on the rail 20 by the power of the motor 30, and the power roller 22 rotates by the power of the motor 28. Further, 38 is a linear arrangement of position sensors, which is used to confirm the position of the power truck 16.

In addition to this, the power truck 16 is provided with a speed sensor and an acceleration sensor so that its position, speed, and acceleration can be checked at all times.

Explain the operation of the device. Vehicles entering warehouse floor 4 are
It self-propels to parking lot 11, and the crew gets off there. The subsequent warehousing work is performed automatically, and the occupants only have to enter the shopping center or the like within one store through a passageway (not shown). In the case of leaving the garage, the occupants only have to get into the vehicle in the exit area I2 through the pedestrian passageway 13 and exit from the floor 6 by themselves. In this embodiment, since there is no reversal of the direction of the vehicle, the vehicle that entered the floor 4 exits to the floor 6 in the same direction. Therefore, advancing the vehicle to the floor 6 does not require a change in direction. Furthermore, if a pedestrian passageway 13 is provided between the two, the flow of people will become natural.

A vehicle stopped at a warehouse II is moved to an elevator 9 by power rollers 22. When the elevator 9 arrives at the parking floor 14, the vehicle is moved to the power truck 16 again by the power rollers 22. Note that here, the parking of the vehicle in the parking lot II and the movement of the elevator 9 are performed simultaneously in parallel,
Reduce waiting time. Also, elevator 9 parking floor 1
4 and the movement of the power truck I6 are performed simultaneously to shorten the time required for moving the vehicle.

The power truck 16 that has received the vehicle runs on the rail 20 by a motor 30. In this way, the power trolley 1G
The running speed of the vehicle can be made extremely high. For example, suppose that the power truck I6 is towed by rollers or chains instead of the rails 20. The power truck 16 cannot be pulled 1° at high speed with rollers or chains. If the diameter of the roller is small, the speed of the power truck I6 cannot be increased, and if the diameter is increased, the power truck 1G will shake violently. Also, even if chains and gears are used, it is difficult to move the power truck ■6 at high speed. Therefore, the rails 20 are used to allow the cart 16 to move by itself at high speed. Note that with rollers, chains, etc., the power equipment must be spread over the entire floor of the parking floor 14, which increases equipment costs.

Power truck 16 is a designated parking pallet! When the vehicle stops at position 8, the power roller 22 moves the vehicle to the parking pallet 1B.
Move to. The movement of the trolley 16 is controlled by a central control computer using a position sensor, speed sensor, and acceleration sensor.

In addition to this, the inventor also considered fixing the vehicle to a pallet and moving the vehicle together with the pallet, instead of moving the vehicle with rollers. But this is elevator 9
This will cause the power truck 16 to make unnecessary reciprocating movements, and the functionality of the multi-level parking market will deteriorate. For example, consider the case where a vehicle is transferred from the elevator 9 to the power truck 16. If the elevator 9 and the power truck 16 do not share a pallet, in order for the power truck 16 to pick up a vehicle, it is necessary to pick up an empty pallet at a different position first. Conversely, when moving the vehicle from the power truck 16 to the elevator 9,
If the power truck 16 does not return the empty pallet to its original position after the vehicle is moved, the next vehicle will not be able to leave the warehouse. As a result, the power truck I6 has to transport an empty pallet every time it transports a vehicle, and the efficiency of the power truck I6 is reduced to 1/2.
decreases to

Next, consider the case where a vehicle and a parking pallet are treated as a complete set. In this case, when moving the vehicle between the elevator 9 and the power truck +6, the vehicle is moved together with the pallet. In this case, to store the vehicle, first load the empty pallet onto the elevator 9 using the power truck 1G, then the elevator 9 will load the empty pallet onto the elevator 9.
I will wait until I get off at 57 to reach A4 before entering the train. When carrying out the next warehousing, similarly, empty pallets must be loaded onto the elevator 9 first. In the case of goods issue,
When the vehicle floats, an empty pallet remains in elevator 9. The elevator 9 cannot begin the next unloading operation until the empty pallet is returned to its original position using the power truck 16.

Therefore, if the pallet I8 is fixed to the parking floor 14 and only the vehicle is moved using the power rollers 22, this problem will be solved.

If the power truck 16 is made to run on the rails 20 to increase its movement speed and the pallet is fixed to eliminate wasteful reciprocating motion, the speed at which vehicles enter and exit the elevator 9 becomes a problem.

This is because this work must rely on the crew's self-propulsion and is the slowest process.

Therefore, in this embodiment, the storage area 11 and the storage area 12 are separated from the elevator 9, and it is possible to stop a vehicle at the storage area 11 and start a vehicle from the storage area 12 at the same time as the elevator 9 goes up and down. .

FIG. 6 shows the operation mode of the embodiment, taking as an example the case when a continuous number of people leave the vehicle. The process for moving vehicles in and out of the warehouse separately is simple and is obvious from the process for continuous inbound and outbound vehicles, so it is omitted here.

FIG. 7(A) shows an operating mode in which all operations are performed serially, and FIG. 7(T3) shows an operating mode in which ascending and descending of the elevator 9 and movement of the power truck 16 are parallelized. Although these figures show an example of a vehicle leaving the warehouse, the same applies when the vehicle enters the warehouse. Further, FIG. 8 shows an operational algorithm of the embodiment. Note that among the symbols such as 2-1 in FIG. 8, the first 2 represents the number of the vehicle being processed, and the second 1 represents each process in the processing cycle.

Regarding the exit station 12, process 0 refers to the movement of the vehicle by the power rollers from the elevator 9, and process I refers to the self-propulsion of the vehicle by the occupant.

Regarding the elevator 9, process 1 is to move the elevator 9 to the parking floor, and process 2 is to move the elevator 9 to the parking floor, and process 2 is to move the elevator 9 to the parking floor.
Process 3 refers to the movement of the elevator 9 to the exit floor.

Further, process 4 refers to the movement of the vehicle to the exit station 12 using power rollers.

Regarding the parking floor I8, Process I moves the power truck 16 to the parking pallet 18, Process 2 moves the vehicle to and from the parking pallet using power rollers, and Process 3 moves the vehicle to the front of the elevator 9. Regarding the movement of the power truck 16, process 4 refers to the transportation of the vehicle to the elevator 9 by power rollers.

Assume that there is a continuous request to leave the vehicle.

In the embodiment, the door of the waiting elevator 9 is opened as soon as the exit station 12 becomes vacant, and the vehicle is sent out from the elevator 9 to the exit station 12 using the power rollers 22. This operation is performed after two conditions are met: the elevator 9 has finished moving and the exit station 12 is empty. Self-propelled unloading is the slowest operation, and in many cases the elevator 9 will wait on the unloading floor 6. Therefore, the next vehicle will arrive at the same time as the previous vehicle leaves. Furthermore, in the embodiment, the vehicle may self-propel not inside the narrow elevator 9 but at the exiting station 12 and the receiving station 11 which are wide outside. Therefore, there is little psychological need for the occupants, and the large space allows for easy self-propulsion.

When the work of moving the vehicle using the power rollers 22 is completed, the occupant gets on the vehicle and the vehicle leaves the garage. At the same time, the elevator 9 moves 4 to the next parking floor. On the other hand, independently of this, each power truck 16 moves the vehicle that has received the command to the front of the elevator 9. That is, the power truck 16 (moves) to the required parking pallet 18, loads the vehicle from the parking pallet 18 onto the power truck 1G using the power rollers 22, and moves to the front of the elevator 9. Then, waits for the arrival of the elevator 9. , or when the movement of the power truck 16 is mentioned, the elevator 9 waits for the arrival of the power truck tC, and then moves the vehicle using the power rollers 22. Here, the elevator 9 moves up and down,
The movement of the power truck 1G is made to proceed at the same time.

Thereafter, the elevator 9 moves to the exit floor 6, waits until the exit station I2 becomes vacant, and then sends out the vehicle.

Of these tasks, the ones that need to be synchronized are elevator 9 and the warehousing station! There are two types of vehicle movement: (1) and vehicle movement with the exit station 12, and vehicle movement between the elevator 9 and the powered trolley. So there is a warehousing group 11 and a warehousing group! 2. Elevator 9, power trolley I6
The operations of each element of are proceeded simultaneously, and the slowest one is matched.
All you have to do is take the time to wait.

Here, we will consider the processing time for warehousing and retrieval. In the case of continuous entry and exit, the slowest is usually the self-propelled entry and stop of the vehicle to the warehousing station 11 and the self-propelled departure of the vehicle from the exit station 12. Therefore, as soon as the previous vehicle completes its self-propulsion to the warehousing station or self-propulsion from the warehousing station, it becomes possible to process the next vehicle. When entering and leaving the warehouse in one piece, since the elevator 9 is already waiting at the warehousing station It, the movement of the vehicle to the elevator 9 by the power rollers is started at the same time as the self-propelled entry into the warehousing station is completed. Further, when leaving the garage in pieces, the power truck 16 moves the necessary vehicles to the front of the elevator 9 at the same time as the elevator 9 moves to the parking floor 14. Therefore, the actual time required is only the round trip time of the elevator 9.

The algorithm shown in FIG. 8 will be explained. When receiving a command to enter or exit the warehouse, the elevator 9, the parking station IL, the parking lot 12, and the powered trolley! Each element of 6 enters a new command at the end of its respective queue. Each element processes the command from the head of its own queue, and when its own queue is finished, it deletes the head of the queue and starts processing the next command in the queue. There is unevenness in the speed and burden of each element. The loading area 11 and the loading area 12 have the highest load, the elevator 9 has the second highest load, and the power truck 1G has the lowest load. Thereupon, the vehicle receiver waits for the delivery partner's preparations to be completed (in FIG. 8, this is called positioning), and then the vehicle receiver performs the handover. If alignment conditions are not met, the element that completed processing first enters the waiting state. When the receiving and passing operations are completed, the element that completed the work processes the next command. Elements that have not received commands (for example, the power truck ! 6 on the floor that has not received the entry/exit command) go into a dormant state.

[Effects of the Invention] In this invention, the moving speed of the cart is increased and the time required for vehicle movement is shortened. This makes it possible to enter and exit vehicles in a short time even when using a large multi-story parking lot.

In addition, in this invention, the elevator and the exit area are separated,
To make it possible for one person to move up and down an elevator and move a vehicle in and out of a warehouse in parallel.

This invention further eliminates the space for vehicles to run themselves, thereby reducing the volume of the parking lot per vehicle. Also, there is no need to use a gate to enter and exit the parking floor.

Furthermore, in this invention, the exhaust gas emitted from the vehicle is iIλ
Removes a small amount of negative impact on the surrounding area.
