BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lifting control method and device for a mechanical parking device.

[0002]

2. Description of the Related Art FIG. 10 shows a mechanical parking system which is the background art of the present invention. The mechanical parking device shown in the figure is a so-called elevator type multi-level parking device, and an elevating platform 2 for transporting a vehicle is lifted up and down in a central portion of a parking structure 1 that supports the multi-level parking device. A plurality of stages of parking shelves 3L and 3R for parking the vehicle are provided on both left and right sides of the elevating space of the elevating table 2 while being capable of being provided.

On the parking shelves 3L and 3R, pallets (not shown for simplification in FIG. 10) to be mounted on the vehicle are mounted, respectively, and the vehicle is parked while being mounted on the pallet. It is configured to be stored in the shelves 3L, 3R.

A vehicle loading / unloading port 5 is provided on the ground for vehicle entry, and a pit portion at a position of the vehicle loading / unloading port 5 has a lift mechanism 6 for lifting the pallet to change its direction. A conversion device 7 is provided.

FIG. 11 is a block diagram showing the entire structure of a conventional elevator type multi-level parking apparatus.

As shown in the figure, the lifting table 2 is framed in a substantially rectangular shape, and its four corners are suspended by wire ropes 9a, 9b, 9c, 9d as suspending ropes. ing. These four wire ropes 9a, 9b, 9c and 9d are used as the deflecting wheels 10a, 10b, 10c and 1 provided on the ceiling of the parking structure 1, respectively.
After passing 0d, it will be collected in one place toward the driving vehicle 11,
Further, it is pulled out downward and connected to the balance weight 12.

The drive wheel 11 is configured to be rotationally driven in both forward and reverse directions by a drive motor 13.

Reference numeral 14 denotes an elevator control device for controlling the drive of the drive motor 13 in response to a necessary command by operating the operation panel 15, and an encoder 16 which is a position detecting means attached to the shaft of the drive motor 13. Since the number of pulses from is counted and stored, the position of the lift 2 can always be known.

In addition, the vehicle has a lifting platform 2 via a pallet.
It is supposed to be placed on top.

As shown in FIG. 12, this pallet 18
Has a sled 18a at the bottom and is movable in the left-right direction, and the vehicle is transferred and stored in the parking shelves 3L, 3R on the target floor while being placed on the pallet 18.

As shown in FIG. 1, the pallet 18 is formed by bending a steel plate in order to reduce the weight as much as possible while maintaining the bending strength.
8c, 18d and concave vehicle entry surfaces 18e, 18f through which the tires of the vehicle pass.

The operation of storing a vehicle in such a conventional elevator type multi-level parking apparatus is configured as follows.

First, the person in charge of the parking device or the user himself / herself operates the operation panel 15 of the elevator control device 14 of the parking device.
Is operated to search for empty parking shelves 3L, 3R, and the pallet 18 of the parking shelves 3L, 3R is called.

The elevating table 2 moves to the floor of the empty parking shelves 3L, 3R, and the upper surface of the elevating table 2 is aligned with the floor surfaces of the parking shelves 3L, 3R and stopped. Then, the parking shelves 3L, 3R
Alternatively, a horizontal drive means (not shown) provided on the elevator 2 moves the pallet 18 of the parking shelves 3L, 3R to the elevator 2
Move in the direction and place.

The elevating table 2 firmly holds the pallet 18 by a lock mechanism (not shown), descends to the vehicle loading / unloading port 5 position, and stops. In this case, the stop position of the lifting platform 2 is the vehicle entry surface 18e, 1 of the vehicle of the pallet 18.
The height of 8f and the height of the floor surface of the vehicle loading / unloading port 5 are configured to match.

A user puts his or her own vehicle into the pallet 1
8, when the user gets off the vehicle, the lift 2 rises and stops at the positions of the previous empty parking shelves 3L, 3R, and the vehicle together with the pallet 18 is horizontally driven by the parking shelves 3L, It is moved horizontally in the 3R direction and stored in the parking shelves 3L, 3R.

In the case of leaving the warehouse, the operation is almost the reverse of the above, and the person in charge of the parking device or the user himself operates the operation panel 15 of the elevator control device 14 of the parking device to mount the user's vehicle. When the pallet 18 placed is called, the elevator 2 moves to the parking shelves 3L, 3R and stops, and the vehicle is horizontally moved and placed on the elevator 2 together with the pallet 18. Descends and stops at a position where the height of the vehicle entry surfaces 18e and 18f of the pallet 18 of the vehicle loading / unloading port 5 and the height of the floor surface of the vehicle loading / unloading port 5 match.

Then, after changing the direction of the vehicle by the pallet direction changing device 7, the user gets into the vehicle,
It was configured to leave from the vehicle loading / unloading port 5.

However, since the lifting platform 2 is set so as to stop at a position where the heights of the vehicle entry surfaces 18e and 18f of the pallet 18 and the floor surface of the vehicle loading / unloading port 5 coincide with each other. When the vehicle is placed on the lift 2 and is under load, the wire ropes 9a, 9b, 9c, 9d that suspend the lift 2 are slightly extended, and the vehicle entrance / exit 5, when the vehicle is unloaded from the lifting platform 2, that is, the pallet 18, the load on the lifting platform 2 is reduced and the wire ropes 9a, 9b, 9c, 9d are reduced.
Trying to return to the original length, the lifting platform 2 is pulled up, the vehicle is in a slanted state, and the bottom part thereof is the convex part 1 of the pallet 18.
There is a problem of touching the tip of 8c, and
The bottom of the vehicle could be scratched, damaging important exhaust gas pipes and other parts.

Therefore, in order to solve the above-mentioned problems, the parking devices disclosed in Japanese Patent Laid-Open Nos. 4-363475 and 5-18134 are proposed.

That is, according to the parking device disclosed in the above-mentioned Japanese Patent Laid-Open No. 4-363475, when the vehicle is mounted on the elevating table, the parking position is a fixed amount compared to the stop position when the vehicle is not mounted. It is controlled so as to stop at the lower position, and prevents a step due to the lifting of the lifting platform due to the restoring force of the wire rope when the vehicle is unloaded from the lifting platform.

Further, according to the parking device disclosed in the above-mentioned Japanese Patent Laid-Open No. 5-18134, an arm which is driven to move back and forth is provided on the elevator, and the elevator is lowered with the arm protruding so that it is placed on the mount. By positioning and fixing and releasing the tension of the support rope that suspends the lifting platform, lifting of the lifting platform that occurs when the vehicle is lowered from the lifting platform is prevented.

[0023]

However, in the parking device disclosed in Japanese Unexamined Patent Publication No. 4-363475, the problem due to the lift of the lift table when the vehicle is lowered from the lift table side can be solved. No consideration is given to the sinking of the lifting platform when the vehicle is mounted on the platform side. Then, when the lifting platform sinks, a detection error may occur when the height of the vehicle is detected by the height regulation detection unit that regulates the height of the vehicle.

Further, in the parking device disclosed in the above-mentioned Japanese Patent Laid-Open No. 5-18134, the lifting table rises when the vehicle is lowered from the lifting table side, and the lifting table when the vehicle is mounted on the lifting table side. However, it is necessary to provide an arm that can move forward and backward and a drive mechanism that drives the arm to move back and forth, which has a drawback of complicating the structure of the lift.

Therefore, an object of the present invention is to effectively prevent the lifting and lowering of the lifting table due to the extension of the suspended rope, thereby preventing damage to the bottom of the vehicle and preventing the detection error of the vehicle height limitation. An object of the present invention is to provide a lifting control method and device for a parking system.

[0026]

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings, but the technical scope of the present invention is not limited thereto.

FIG. 1 is a block diagram showing the configuration of an elevator control device for a mechanical parking apparatus according to the first embodiment of the present invention. The same components as those described above are designated by the same reference numerals, and their description will be omitted. To do.

In the figure, the pit portion provided with the pallet direction changing device 7 is contacted with the lower side of the lift table 2 so as to be freely contactable and separable when the lift table 2 is lowered, and the lowering of the lift table 2 is restricted. Is provided with the stopper 20, and in the state where the lifting platform 2 is supported in abutting manner by the stopper 20,
The heights of the vehicle entry surfaces 18e and 18f of the vehicle W of the pallet 18 mounted on the lift 2 and the floor surface of the vehicle entrance / exit opening 5 are configured to match.

The stoppers 20 are provided at four positions corresponding to the respective corners of the lift table 2.

The elevator board position management section 21 for controlling the stop position of the elevator board 2 receives a signal from the operation of the operation panel 22.
At this time, the lift table position management section 21 confirms the current position of the lift table 2 by the encoder 16 as a position detection means attached to the rotary shaft of the drive motor 13, and confirms the current position of the lift table 2.
The inverter 24 is instructed to move up and down until the positions Y of L and 3R are reached, and the inverter 24 receives the instruction and sends necessary electric power to the drive motor 13.

When the position of the lift 2 arrives at the target position Y, the signal from the lift position management unit 21 to the inverter 24 is stopped and the lift 2 is moved to the position Y of the target parking rack 3L, 3R.
Stop with.

Further, a vehicle detector 2 as a vehicle detecting means.
The detection signal 5 is sent to the lift table position management section 21. When the elevator 2 is called to the vehicle loading / unloading port 5, the vehicle detector 2 installed on the elevator 2
If it is determined that the vehicle W is not mounted on the lifting platform 2 based on the signal from the vehicle 5, the normal stop position (pallet 1
The vehicle is stopped at a position where the heights of the vehicle entry surfaces 18e, 18f of No. 8 and the floor surface of the vehicle loading / unloading port 5 match. vice versa,
If it is determined that the vehicle W is mounted, the lift mechanism 6 of the pallet direction changing device 7 is lifted and the vehicle W is stored in the lift mechanism 6 of the pallet direction changing device 7, and only the lifting platform 2 is stoppered. It is stopped at the normal stop position that abuts 20. Then, after that, the lift mechanism 6 is rotated by a predetermined angle to be lowered, and the pallet 18 is returned to the lift table 2 in a state where the direction of the vehicle W is changed.

The vehicle detector 25 may be provided with a piezoelectric element on the upper surface of the lifting table 2 at a position where the pallet 18 is placed, or a photoelectric element may be provided at a height across the vehicle W of the lifting table 2. A device may be provided to detect the vehicle W.

Next, with reference to the flow chart of FIG. 2, the operation of moving the lifting platform 2 to the vehicle loading / unloading port 5 by the lifting control device of the mechanical parking device configured as described above will be described.

First, the operation panel 22 is operated to call the desired pallet 18 to the vehicle loading / unloading port 5 (step S
1).

Next, according to the signal from the vehicle detector 25,
The lift position management unit 21 determines whether the vehicle W is mounted on the pallet 18 (step S2).

The elevator board position management unit 21 includes an encoder 16
It counts and stores the pulse signals from the
The current position X of is known. On the other hand, each parking shelf 3R, 3
Since data regarding L and the position of the vehicle loading / unloading port 5 is input to the position storage unit 23, if it is determined in step S2 that the vehicle W is not mounted on the pallet 18, the position storage is performed. The position Y of the vehicle entrance / exit opening 5 is obtained based on the data stored in the section 23, and is set as the target position P = Y (step S3),
Until the value of the position X of the lift 2 reaches the target position P,
A command is sent to the inverter 24 to lower the lifting table 2 (steps S5, S6, S7). Then, the elevating table 2 stops at a normal stop position where it is abutted and supported by the stopper 20.

If it is determined in step S2 that the vehicle W is mounted on the pallet 18,
As shown in FIG. 3, the lift mechanism 6 of the pallet direction changing device 7 is raised (step S4), the position Y of the vehicle loading / unloading port 5 is determined in the same manner as above, and the target position P = Y is set (step S4). S3), until the value of the position X of the lifting table 2 reaches the target position P, a command is sent to the inverter 24 to lower the lifting table 2 (steps S5, S6, S7).

In the descending process of the lift table 2, when the lift table 2 reaches the lifted position of the lift mechanism 6, the pallet 18 carrying the vehicle W is deposited on the lift mechanism 6 side, and thereafter only the lift table 2 is lowered. I will do it. Then, as shown in FIG. 4, the elevator base 2 is stopped at the normal stop position where it abuts the stopper 20, and the pallet 18 is supported in a lifted state by the lift mechanism 6 of the pallet direction changing device 7. To be

In this case, the extension of the wire ropes 9a, 9b, 9c, 9d due to the weight of the vehicle W is removed when the pallet 18 is deposited on the lift mechanism 6 side.

When the lift table 2 is stopped at the normal stop position, as shown in FIG. 5, the lift mechanism 6 is rotated by a predetermined angle (for example, 180 degrees) and then lowered, as shown in FIG. , The pallet 18 is returned to the lift table 2 with the direction of the vehicle W changed (steps S8, 9).

In this case, the weight of the vehicle W is applied to the lift table 2, but since the lift table 2 is supported by the stopper 20, the lift table 2 does not sink. Therefore, even if the vehicle W is unloaded from the pallet 18 in this state, no tension is applied to the wire ropes 9a, 9b, 9c, 9d, the lifting of the lifting platform 2 can be prevented, and the convex portion 18c of the pallet 18 can be prevented. It is possible to effectively prevent contact between the vehicle and the bottom of the vehicle W.

When the vehicle W gets on the pallet 18 on the lifting table 2 at the vehicle loading / unloading port 5, since the lifting table 2 is supported by the stopper 20, the wire ropes 9a, 9b, 9c, 9d. Sinking due to the expansion of the vehicle W does not occur, and a detection error by the height regulation detection unit for regulating the height of the vehicle W when the vehicle W is stored can be effectively prevented.

7 to 9 show the second embodiment. The same components as those of the first embodiment are designated by the same reference numerals and the description thereof will be omitted.

That is, in this embodiment, the pit portion is not provided with the pallet direction changing device 7, and the other structure is the same as the above.

When the elevator 2 is called to the vehicle loading / unloading port 5, the elevator position management unit 21 detects the vehicle W on the elevator 2 based on the signal from the vehicle detector 25 installed on the elevator 2. If it is determined that it is not mounted, it will be stopped at the normal stop position. If it is determined that the vehicle W is mounted, the wire ropes 9a, 9b, 9c and 9d are controlled to be unwound from the normal stop position by a fixed amount m. In this case, the elevating table 2 is supported by the stopper 20 in abutment and stopped at the normal stop position, and the tension of the wire ropes 9a, 9b, 9c, 9d is slightly relaxed.

The ideal value of the constant amount m is the vehicle W
Is the amount that can be pulled up by the restoring force of the wire rope when the weight of the wire rope is removed, and can be easily calculated by the expansion / contraction rate of the wire rope, the weight of the vehicle, and the distance from the ceiling of the wire rope. .

Next, the operation of moving the lifting platform 2 to the vehicle loading / unloading port 5 will be described with reference to the flowchart of FIG.

First, similarly to the first embodiment, the operation panel 2
2 is operated to call the target pallet 18 to the vehicle loading / unloading port 5 (step S11).

Next, according to the signal from the vehicle detector 25,
The lift position management unit 21 determines whether the vehicle W is mounted on the pallet 18 (step S1).
2).

The lift table position management section 21 includes an encoder 16
It counts and stores the pulse signals from the
Of the current position X of the parking rack 3R, 3R
Since data regarding L and the position of the vehicle loading / unloading port 5 is input to the position storage unit 23, if it is determined in step S12 that the vehicle W is not mounted on the pallet 18, the position storage is performed. The position Y of the vehicle entrance / exit opening 5 based on the data stored in the section 23.
And set as the target position P = Y (step S1
3) Send a command to the inverter 24 to lower the lifting platform 2 until the value of the position X of the lifting platform 2 reaches the target position P (steps S15, S16, S17). Then, the elevating table 2 stops at a normal stop position where it is abutted and supported by the stopper 20.

If it is determined in step S12 that the vehicle W is mounted on the pallet 18, the target position P = Y-m is set (step S14).
Until the value of X reaches P, the elevator 24 lowers the platform 2 (steps S15, S16, S17).
Although a command is sent, the elevator table 2 contacts the stopper 20 at the normal stop position and the descending is restricted, and the wire ropes 9a, 9
b, 9c, and 9d are unwound by a fixed amount m, and the wire ropes 9a, 9b, 9c, and 9d are slightly loosened there (see FIGS. 8 and 9).

As a result, when the vehicle W descends from the lift table 2, the lift table 2 does not rise and the pallet 18
The contact between the convex portion 18c and the bottom portion of the vehicle W can be effectively prevented.

When the vehicle W gets on the pallet 18 on the lift 2 at the vehicle loading / unloading port 5 position,
As in the embodiment described above, since the lifting platform 2 is supported by the stopper 20, the wire ropes 9a, 9b, 9c, and 9d do not sink, and the height of the vehicle W when the vehicle W is stored is reduced. It is possible to effectively prevent a detection error due to the height regulation detection unit for regulation.

In the second embodiment described above, the structure in which the pallet direction changing device 7 is not provided is illustrated, but the structure in which the pallet direction changing device 7 is provided can be similarly applied. . In this case, after the lifting platform 2 is stopped at the landing position where it is abutted and supported by the stopper 20, the tension of the wire ropes 9a, 9b, 9c, 9d causes the vehicle W to move.
Wire ropes 9a, 9b, 9 when the weight of is removed
The unwinding operation may be performed by the predetermined amount m until the restoring forces of c and 9d are removed, and then the pallet direction changing device 7 may be controlled to change the direction of the vehicle W.

Further, the mechanical parking device to which the present invention is applied is not limited to the elevator type three-dimensional parking device as shown in each of the above-described embodiments, but a mechanical type parking device is generally used in which a lifting platform is hung by a rope or the like. Any parking device is acceptable.

[0060]

As described above, according to the raising / lowering control method of the mechanical parking apparatus of the present invention, the stopper for supporting the raising / lowering table from the lower side at the vehicle entrance / exit position and restricting the lowering of the raising / lowering table is provided. When the elevator is lowered to the vehicle loading / unloading position, it is detected whether or not the vehicle is mounted on the pallet on the elevator, and if the vehicle is mounted, the lift mechanism of the pallet direction changing device is used. The lift table is lowered in the raised state, and after the pallet is supported by the lift mechanism, the lift table is further lowered to stop at the vehicle loading / unloading position supported by the stopper, and then the lift mechanism is lowered. The pallet is then returned to the top of the lift table, and according to the first lift control device of the mechanical parking device, the lift table is supported from the lower side at the vehicle entrance / exit position to regulate the lowering of the lift table. And the stopper to And position detecting means for detecting a lifting table of the current position, a vehicle detection means for detecting the presence or absence of the mounting of the vehicle to a pallet on the lifting platform is provided on the lifting platform,
A lift table position management unit that controls a stop position of the lift table according to a signal from the position detection unit and a signal from the vehicle detection unit is provided. When the vehicle detection means detects that the vehicle is mounted on the pallet when the pallet is lowered to the position, the lift mechanism is lowered while the lift mechanism of the pallet direction changing device is raised, and the pallet is supported by the lift mechanism. After that, the elevator is further lowered to stop at the vehicle loading / unloading position supported by the stopper, and then the lift mechanism is lowered to control the pallet to be returned to the elevator. When lowering the vehicle from the elevator pallet at the exit, the tension due to the weight of the vehicle has not already been applied to the suspended rope, and the lifting of the elevator can be effectively prevented. . Further, when the vehicle gets on the pallet of the elevator, the elevator is supported by the stopper, so that the sink of the elevator can be effectively prevented. Therefore, there is an advantage that the damage of the bottom of the vehicle and the detection error of the height limitation of the vehicle can be prevented.

Further, since the pallet on which the vehicle is mounted is already supported by the lift mechanism of the pallet direction changing device at the raised position before landing on the lifting platform at the vehicle entrance / exit position.
There is also an advantage that the time for changing the direction of the vehicle can be shortened.

Further, according to the second lifting control device of the mechanical parking apparatus, the stopper for supporting the lifting table from the lower side at the vehicle entrance / exit position to restrict the lowering of the lifting table, and the current lifting table. Position detection means for detecting the position, vehicle detection means provided on the elevator to detect the presence or absence of a vehicle mounted on the elevator, by a signal from the position detector and a signal from the vehicle detector, An elevator platform position management unit for controlling a stop position of the elevator platform, and the elevator platform position management unit mounts the vehicle on the elevator platform by means of vehicle detection means when the elevator platform is lowered to the vehicle loading / unloading port position. When it is detected, after the elevator arrives at the vehicle loading / unloading position supported by the stopper, the hanging rope is controlled to be further unwound by a certain amount. Similarly, entering and leaving the vehicle When unloading from the pallet lifting platform vehicle in the mouth, the already hanging rigging not act tension due to the weight of the vehicle, the lifting platform lift can be effectively prevented. Further, when the vehicle is loaded on the pallet of the elevator, the elevator is supported by the stopper, so that the sink of the elevator can be effectively prevented. Therefore, there is an advantage that the damage of the bottom of the vehicle and the detection error of the height limitation of the vehicle can be prevented.
