Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a vehicle entry mechanism for an elevator-type multilevel parking system.

BACKGROUND OF THE INVENTION In recent years, elevator-type multi-story parking systems have become popular with the aim of increasing the speed, reducing noise, and lowering the cost of tower-type multi-story parking systems.

An elevator-type multilevel parking system is provided with a lift room in the center of the parking building where an elevator goes up and down, and a storage room in which vehicle storage shelves are arranged vertically in multiple stages on the left and right sides of the lift room. Each shelf can be moved between the storage room and the elevator room, and vehicles can be transferred from the elevator to the storage shelf and from the storage shelf to the elevator by means of an abutment between the elevator fork and the storage shelf fork. A variety of devices have been developed in the past (for example, Japanese Patent Application Laid-open No. 62-8
(See Publication No. 6272).

Furthermore, as described above, there is an elevator-type multi-story parking system comprising an elevator that moves up and down in a lifting room, a fork-type vehicle delivery mechanism, and a storage shelf traversing mechanism, and the storage shelf traversing mechanism is installed in a building. In principle, a single drive motor can be used to traverse multiple storage shelves in a highly selective manner, thereby greatly reducing the number of power sources for the traversing mechanism, simplifying the control system and making maintenance easier. The present applicant has previously developed a system that can reduce the number of people and exit time, and improve parking efficiency, and is currently applying for a patent as Japanese Patent Application No. 1-273451.

Problems to be Solved by the Invention In elevator-type multilevel parking systems, the entry and exit entrances for vehicles are often shared at one location due to space constraints.

In such cases, for the convenience and safety of users, it is necessary to move forward when exiting the garage, and a turntable is installed in the center of the entrance/exit level 9 (usually the first floor). The unloaded car that has been taken down by the elevator is transferred onto the turntable at the entry/exit level 9 using the bridge abutment of the fork comrades, and the turntable is rotated 180 degrees so that it can be exited by moving forward. (For example, Japanese Patent Application Laid-open No. 62-26
8475).

However, the following problems arise in the case where turntables are provided on the entrance and exit floors.

In other words, it takes at least about 20 seconds for the vehicle to exit the garage to descend to the entrance/exit level 9, turn the vehicle 180 degrees, get in the vehicle, start the engine, and exit the vehicle. Until the outgoing car has exited, the next incoming car cannot enter the entry/exit level, and must wait to avoid the incoming car's path. It takes at least about 20 seconds after the vehicle has exited the parking lot until the next vehicle enters the entrance/exit level 9, stops the engine, the driver exits the vehicle, and exits the facility. If this is done continuously, it will take at least about 40 seconds from when the elevator picks up the outgoing car and descends to the entry/exit floor until it picks up the next incoming car and begins to ascend. It turns out.

The above-mentioned prior art (invention of Japanese Patent Application No. 1-273451)
When using the elevator, the average (middle floor) elevator entry and exit time only takes about 30 seconds.
As mentioned above, the fact that it takes about 20 seconds for each entry and exit is extremely inconvenient and could be an issue for improvement.

The main object of the present invention is to provide an entry/exit mechanism that can significantly shorten the time required for entry/exit of a vehicle as described above.

Means for Solving the Problems The present invention is based on, for example, the above-mentioned prior art (Japanese Patent Application No. 1-27345).
In an elevator-type multilevel parking system as shown in No. 1), the entry of a vehicle.

A transverse shelf for entering cars and a transverse shelf for exiting cars each having a fork that enables delivery of vehicles by an abutment with the elevator fork in the elevator hoisting room are installed on the left and right sides of the elevating room on the coming floor. A traverse mechanism is provided so that the vehicle can be traversed into the elevator compartment and to the original left and right sides, and a traversal mechanism is provided that allows the traversal shelf for the entering vehicle and the traversing shelf for the destination vehicle to traverse separately or both at the same time. The present invention is characterized in that a turntable with a fork is installed in the central part of the elevator cabin on the floor below the 9th boarding floor to enable delivery of vehicles by means of an abutment with the elevator fork.

As described above, when unloading and unloading are performed consecutively, for example, while the elevator is in operation, the next incoming car will drive onto the transverse loading shelf, the engine will be stopped, and the driver will exit the car and exit. The elevator carrying the outgoing car enters the elevator, descends to the floor below the departure level, transfers the outgoing car onto the turntable, turns 1800 degrees, then returns to the elevator to receive the outgoing car and enters. It ascends to the boarding floor, where the boarding car transversal shelf moves into the elevator elevator room to receive the outgoing car, and then the boarding car boarding shelf carrying the outgoing car and the boarding car carrying the incoming car. At the same time, the transverse shelf for cars moves sideways, the transverse shelf for the coming car returns to its original position, and the transverse shelf for entering cars reaches the elevator elevator chamber, and the passenger gets into the outgoing car, starts the engine, and moves forward. The incoming car is transferred to the elevator while it is being boarded, and the elevator ascends and can be loaded into the storage shelf on the predetermined floor, so the time required for boarding and boarding is reduced compared to conventional systems. It is possible to significantly reduce the time required and significantly improve parking efficiency.

Example Embodiments of the present invention will be described below with reference to the accompanying drawings.

1 to 5 are diagrams showing an example of a vehicle transfer/loading/unloading mechanism of an elevator type multilevel parking system to which the present invention is applied,
First, an example of an elevator, a vehicle delivery mechanism, and a storage rack traverse mechanism will be explained based on FIGS. 1 to 5.

Vertical guide rails 2 are installed at the four corners of the elevator room A, and the elevator 33 is guided by the guide rails 2 and is moved up and down inside the elevator room A by the drive of the elevator motor 31 via the elevator chain l. It is supposed to be done.

The elevator 33 connects horizontal left and right side beams 3° 4, vertical beams 5 fixed downward at both front and rear ends of the side beams 3 and 4, and the lower ends of the left and right vertical beams 5 and 5. The vehicle is constructed integrally with the front and rear cross beams 8 and a plurality of elevator forks 9 that protrude inward from the left and right side beams 3.4, respectively, and the front, rear, left and right wheels are mounted on the elevator forks 9. can be placed.

The longitudinal beam 5 is guided by a loose fit on the guide rail 2, and the length of the longitudinal beam 5 is determined by taking into account the strength of the guide function 1 and the vehicle transfer operation between the storage shelves and the like, which will be described later. It is appropriate to set the length to about 0.51. In addition, the cross beam 8 is a main driving wheel 6, which will be described later. It is offset and fixed inward from the lower end of the vertical beam 5 so as not to interfere with the rack traverse mechanism such as the idler ring 7.

In the left and right storage rooms B of the elevator room A, storage shelves 28 for parking are arranged in multiple vertical stages, each of which has a plurality of shelf forks 29 protruding from the left and right that serve as an abutment for the elevator fork 9 of the elevator 33.

The storage shelf 28 has front and rear grooves connected to the auxiliary drive wheels 16 attached to the cross beams 32 of the building. By fitting into the idler ring 27, it is placed and supported so that it can move horizontally.

The left and right auxiliary driving wheels 16 are located at the center portion in the left and right direction of the building cross beam 32 (the portion inside the elevator room A). The main drive wheel 6 and the idler wheel 7 are installed so as to be aligned with the idler wheel 27, and the rotation of the main drive wheel 6 and either the left or right auxiliary drive wheel 16 raises or lowers the storage shelf 28 on either the left or right side from the storage chamber B. It is possible to traverse into the room A and from the elevator room A to the storage room B within the same plane.

The traversing mechanism of the storage shelf 28 includes one driving wheel drive motor 10 installed at the center of the upper part of the building, and the driving wheel drive motor 10.
shaft 11. which transmits the rotation of the shaft to the shaft 15 of the main driving wheel 6 of each floor. Sprocket) 12.13 and chain 14,
The rotation of the shaft 15 of the main driving wheel 6 is controlled by a combination clutch 25 (any combination clutch such as a mechanical, electromagnetic, hydraulic, or pneumatic type can be used) provided on the shaft 15 of the main driving wheel 6. Sprockets 17.1B, 21.22 and chain 19.20 that selectively transmit transmission to either the left or right auxiliary drive wheel 16 by the operation of actuator 26.

The dual clutch 25° actuator 26 is provided behind the guide rail 2 that guides the elevator, so that the traversing mechanism does not interfere with the elevation of the elevator 33 at all.

Although the driving wheel drive motor 10 is used in principle to traverse multiple floors of storage shelves as in the illustrated embodiment,
If the building is tall and has many floors of storage shelves 28, the number of floors is divided into several blow blocks for each floor, and one driving wheel drive motor is installed before and after the elevator room A for each block. The main driving wheels 6 of multiple floors may be driven by the chain 14. Even in this case, the number of driving wheel drive motors is 3 to 4 when divided into 2 blocks, and 5 when divided into 3 blocks. ~6 units are enough. Also, as shown by the imaginary line in FIG. 3, the axis 23 of the front and rear drive wheels 16 and
4 and 24 in the front and rear directions, respectively, and if the shaft 23 and 24 are configured so that the rotation of the shaft 23 and 24 causes the two front and rear drive wheels 16 to rotate integrally, both the front and rear drive wheels 16 can be rotated. or one sprocket) 17.1B.

21.22. Chain 19, 20. The dual clutch 25 and actuator 26 can be omitted.

Reference numeral 30 denotes a vehicle entrance/exit floor (usually the first floor), and the entrance/exit floor 30 is located on the left and right sides of the central elevator room A, that is, on the left and right sides of the storage room B, as shown in Fig. 6.7. Traverse shelf 34 for vehicles on the bottom floor
It has a structure in which a transverse shelf 35 for a vehicle is arranged so that it can be transversed and transversely returned.

The transverse shelves 34, 35 for incoming cars and outgoing cars are shelf forks 34a that abut the elevator forks 9, similar to the storage shelves 28 described above.

It has a structure in which a plurality of steps 35a are protruded from side to side, and steps 34b and 35b for vehicle wheel running are fixedly installed.
The traversing mechanism of the traversing shelves 34 and 35 is connected to the driving wheel drive motor 10 via the chain 14, similar to the traversing mechanism of the storage shelf 28 described above.
This is performed by the rotation of the main drive wheel 6 and the drive wheel 16, which are rotationally driven by the main drive wheel 6 and the drive wheel 16. However, in the above-mentioned traverse mechanism of the storage shelf 28, the dual clutch 25 is used to selectively operate one of the left and right storage shelves in traverse operation, but in the traverse mechanism of the traverse shelf 34, 35, only one of the left and right storage shelves can be operated in traverse operation. The difference is that a multiple clutch 251 is used which is capable of selectively traversing the shelves and simultaneously traversing both left and right shelves. The multiple clutch 251 is switched by an actuator (not shown), and the other mechanisms are exactly the same as the traverse mechanism of the storage rack, and the same parts are denoted by the same reference numerals.

The elevator room A continues to a floor further below the entrance/exit floor, that is, the basement, and there is a turntable 3 for changing the direction of the vehicle to the basement.
6 is installed.

As shown in FIGS. 7 and 8, the turntable 36 includes a motor 37, a drive wheel 38 rotated by the motor 37, and an idler wheel 3.
9 is provided at the tip of the leg leg, and a swivel base 41 has a plurality of forks 42 protruding from the left and right sides of the frame to serve as an abutment for the elevator fork 9, and rotates together at the upper part of the swivel frame 4o. configured.

Next, the loading/unloading operation will be explained below.

Regardless of where the elevator is or what it is doing, as long as the incoming car transverse shelf 34 is empty, the incoming car will drive onto the incoming car transverse shelf 34, the engine will be stopped, and the driving car will exit the vehicle. You can then exit the device.

FIG. 9 shows a case where the elevator 33 is performing an unloading operation when the incoming car enters the incoming car transverse shelf 34.

As shown in FIG. 389 (a), when the elevator 33 carries the outgoing car and descends, the incoming car may already be on the transverse shelf 34 for entering cars.

Enter the elevator 33 with the outgoing car on board, and go to the exit floor 3.
0 and (a) # as shown in the figure! ! When the vehicle reaches the floor, the vehicle is transferred onto the swivel base 41 of the turntable 36 by the bridge abutment between the forks, and the turntable 36 rotates 1800 degrees to change the direction of the vehicle. When the turn is completed, the elevator 33 ascends and transfers the outgoing car on the turning platform 41 onto the elevator fork 9.
0, the elevator fork 9 is on the transverse shelf 34.35
Stop when the level is slightly higher than the fork.

Next, the multiple clutch 251 is activated and the transverse shelf 3 for the boarding vehicle is
5 side drive wheel 16 and main drive wheel 6 are rotated, and the boarding vehicle transverse shelf 35 moves transversely into the elevator room A and stops in the state shown in the figure. Then, the elevator 33 descends a little and transfers the outgoing car onto the incoming car transverse shelf 35 as shown in the figure.

Next, the compound clutch 251 is connected to both the left and right drive wheels 16.1.
6 to be rotated at the same time, and in conjunction with the rotation of the main drive wheel 6, the incoming vehicle transverse shelf 35 and the entering vehicle transverse shelf 34 are simultaneously caused to transverse to the left in the figure (to), and the state shown in FIG. A driver gets into the car, starts the engine, and drives forward. During this time, as shown in (G), the elevator 33 rises and moves the incoming car on the transverse shelf 34 for entering cars to the elevator fork. 9 and stop once 9 Next, the multiple clutch 251 turns on only the drive wheel 16 on the side of the transverse shelf 34 for passenger cars, and as the main drive wheel 6 rotates, the transverse shelf 34 for passenger cars moves ( The elevator returns to its original position as shown in (h) and prepares for the next incoming vehicle to enter, and then ascends to a predetermined floor to complete the incoming vehicle.

By doing this, when leaving and entering the warehouse are performed consecutively, it is possible for the incoming vehicle to enter the warehouse, the engine to be stopped, the driver to get off and leave the warehouse, etc. while the unloading operation is in progress, and for passengers to enter the outgoing vehicle, engine start.

Getting out of the vehicle is possible while the incoming vehicle is in operation.

Therefore, in the conventional system in which a turntable was installed on the entry/exit floor 9, the elevator loads the outgoing car and arrives at the entry/exit level 9, until the elevator loads the incoming car and starts ascending. As mentioned above, the required time was about 40 seconds, but the present invention takes about 24 seconds, making it possible to significantly shorten the time required for boarding and exit.

The traverse of the storage shelf 28 is performed by selective operation of the multiple clutch 25 on the floor and the rotation control of the drive wheel drive motor 10, and the transfer of vehicles between the storage shelf 28 and the elevator 33 is performed by a slight lifting/lowering operation of the elevator. It will be done.

Furthermore, if the traversing mechanism of the storage shelf 28 and the traversing shelves 34, 35 is configured as shown in the illustrated embodiment, the number of power sources for traversing can be significantly reduced, simplifying the control system and facilitating maintenance. However, the traversing mechanism is not limited to the illustrated embodiment; for example, each storage shelf is equipped with a power source for traversing, and the traversing shelf 349 for entering vehicles is connected to the traversing shelf 35 for vehicles. It may also be a traversing mechanism in which each of the storage shelves and the traversing shelves 34, 35 is equipped with a traversing power source, and each storage shelf and traversing shelf 34, 35 can be independently traversed by controlling each traversing power source.

Effects of the Invention As described above, the present invention provides an elevator-type multilevel parking system, in which a turntable for changing the direction of the vehicle is provided at the bottom of the elevator chamber where the elevator operates to move up and down in order to enable forward boarding. In the vehicle, a transverse shelf for entering vehicles and a transverse shelf for arriving vehicles are provided on the left and right sides of the elevator room on the entrance/exit floor of the vehicle, respectively, and a transverse shelf for entering vehicles and a transverse shelf for arriving vehicles are respectively provided. By installing a traversing mechanism that traverses the traversing rack for the elevator and the traversing rack for the elevator separately or both at the same time, and by installing a turntable in the elevator room on the floor below the entrance/exit floor 9, the elevator can be moved regardless of the operating position of the elevator. In addition, regardless of whether the turntable is in operation or not, vehicles attempting to enter the warehouse can enter onto the transverse rack for entering vehicles, and at the same time as passengers board the exiting vehicle, start the engine, and exit the vehicle. It is also possible to perform the warehousing operation for the next warehousing vehicle at the same time, and when unloading and warehousing are performed consecutively, the time required for entering and leaving the warehouse can be significantly shortened compared to the conventional method. This can significantly improve parking efficiency and can bring about great practical effects.
