BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a control device for a mechanical parking facility such as an elevator multi-story parking device.

[0002]

2. Description of the Related Art FIG. 3 is a schematic explanatory view of an elevator-type multi-story parking device 1 as a mechanical parking facility. A vehicle 3 is mounted on a central part in a board-shaped parking structure 2 supporting the multi-story parking device 1. A lifting platform 4 to be placed is provided so as to be able to move up and down, and a plurality of stages of parking shelves 6L and 6R for accommodating and parking the vehicle 3 are arranged in spaces on both left and right sides along the lifting path 5 of the lifting platform 4. It is arranged in a shape.

Each of the parking shelves 6L and 6R has a vehicle 3 respectively.
A pallet 7 for mounting is mounted, and the vehicle 3 is configured to be stored in each of the parking shelves 6L and 6R while being mounted on the pallet 7.

As shown in FIG. 4, the elevator 4 is formed in a rectangular shape in plan view, and its four corners have wire ropes 8a, 8b, 8c as hanging ropes, respectively.
8d. These four wire ropes 8a, 8b, 8c, 8d are respectively deflected cars 10a, 10b, 1 arranged on the ceiling 9 of the parking structure 2.
0c and 10d, the winding drum 1 of the hoist 11
The distal end is connected to a balance weight 13 via a relay pulley 12.

Conventionally, a floor detector 14 is provided between the center of the elevator 4 and the center of the hoistway 5 to detect the floor of each floor of the elevator 4. ing. For example, the floor detector 14 is composed of a sensor 14a mounted on the elevator 4 side and strikers 14b provided corresponding to the positions of the parking shelves 6L and 6R on each floor.

[0006] The elevator type multi-story parking device 1
Is as follows.

First, operating the operation panel, the empty parking shelf 6L,
6R, pallets 7 of the empty parking shelves 6L and 6R.
Make a call to.

Then, the elevator 3 is moved up and down to the corresponding empty parking shelves 6L and 6R, the floor is detected by the sensor 14a and the striker 14b, and the parking rack called as the elevator 4 is moved. Pallet 7 between 6L and 6R
Stops at a position where it can be transferred.

Thereafter, pallet lateral transfer means (not shown)
Is operated, and the pallets 7 on the parking shelves 6L and 6R are slid in the direction of the elevator 4, that is, are laterally transported, and are transferred onto the elevator 4.

Next, the lift 4 firmly grips the pallet 7 mounted thereon by a lock mechanism (not shown), descends to the vehicle entrance 16 on the ground floor, and stops.
At this time, the stop position of the elevator 4 is such that the height of the vehicle entry surface of the pallet 7 and the height of the floor surface of the vehicle entrance 16 are substantially the same.

Then, after the vehicle 3 is loaded and placed on the pallet 7, the elevator 4 is raised, and stops at the position of the empty parking shelves 6L and 6R by the detection of the floor detector 14, and the vehicle 3 Of the parking shelves 6L and 6R by the pallet lateral transfer means along the parking shelves 6L and 6R.
Store in R.

In the case of unloading, the operation is substantially the reverse of the above.
When the operation panel is operated to call the pallet 7 on which the vehicle 3 is mounted, the elevator 4 is moved to the parking shelves 6L, 6R.
After the vehicle 3 is moved to the position and stopped, and the vehicle 3 is transported along with the pallet 7 on the elevator 4 and transferred, the elevator 4 is lowered and the height of the vehicle entry surface of the pallet 7 on the elevator 4 is determined. The vehicle stops at a position where the height of the floor of the vehicle entrance 16 substantially coincides.

Therefore, the vehicle 3 is configured to enter the vehicle 3 and exit from the vehicle entrance 16.

When the pallet 7 is transferred by the pallet lateral transfer means between the elevator 4 and each of the parking shelves 6L and 6R, the allowable lateral transfer condition is that the stop position of the elevator 4 is a predetermined position. That is, it is required that the height of the horizontal transfer surface of the pallet 7 of both the lifting platform 4 and the parking shelves 6L and 6R be within a range of ± A (for example, ± 70 mm). Is performed by the sensor 14a and the striker 14b that perform the detection.

[0015]

However, in the above-mentioned conventional structure, the sensor 14a and the striker 14b are provided at the center of the elevator 4 and the center of the elevator 5. The inclination of the elevator 4 due to the leaning of the vehicle 3 mounted on the platform 4, the vehicle 3 and the pallet 7
Since the load fluctuation at the time of horizontal transfer can be detected only at the center of the lift 4 in the left-right direction, the horizontal transfer means of the pallet is parked with the lift 4 in anticipation of the amplification at the left and right ends due to the inclination of the lift 4. It is necessary to provide a structure having a sufficient margin for a step between the horizontal transfer surfaces of the pallets 7 on both the shelves 6L and 6R, and there is a drawback that the structure of the pallet horizontal transfer means is complicated.

The installation accuracy of each machine of the multi-story parking device 1, the adjustment accuracy of the floor detector 14, the stop accuracy of the elevator 4, the inclination due to the eccentricity of the load on the elevator 4, and the load when the pallet 7 is transferred laterally. Each wire rope 8a, 8b, 8 due to fluctuation
If various conditions such as expansion and contraction of c and 8d overlap in the worst case, there is a problem that the above-mentioned tolerance of ± A may be exceeded and the pallet 7 may not be laterally transported.

Further, when the lifting stroke of the elevator 4 is longer, the wire ropes 8a, 8b, 8c, 8d are also longer. Therefore, the vehicle 3 and the pallet 7 are located between the elevator 4 and the parking shelves 6L, 6R. Since the amount of expansion and contraction due to the load fluctuation when transferring the is increased, there is also a problem that the maximum number of accommodated vehicles is limited.

In view of the above problems, the present invention minimizes the influence of the extension and contraction of the hanging rope body, facilitates the transfer of the pallet, and simplifies the structure of the pallet lateral transfer means. It is another object of the present invention to provide a control device for a mechanical parking facility capable of increasing the number of accommodated vehicles.

[0019]

A technical means for achieving the above object is a lifting platform which is suspended by a hanging rope and which can be lifted and lowered by a lifting and lowering operation of the hanging rope. And a plurality of parking shelves arranged in layers along the left and right sides of the hoistway of the hoisting platform, and a pallet on which a vehicle is mounted between the hoisting platform and each parking shelf. In a mechanical parking facility comprising a pallet lateral transfer means and a floor detector for detecting the floor of each floor of the lift platform in order to stop and control the lift at the pallet transfer position of the called parking shelf, A floor detector dedicated to calling the left parking shelf is provided between each of the left parking shelves and the left of the elevator, and between the right parking shelves and the right of the elevator. There is a floor detector dedicated to calling the parking shelf on the right Lies in comprising provided with a level correction control unit for elevation control to the level correcting lifting platform based on the detection data detected by the floor detector.

[0020]

According to the present invention, the floor detector dedicated to calling the left parking shelves and the floor detector dedicated to calling the right parking shelves are provided, respectively, so that the vehicle is mounted leaning on the elevator. Even if the elevator is tilted, the elevator is moved up and down by the dedicated floor detector on the corresponding side of the corresponding left parking shelf or right parking shelf and the elevator according to the called parking shelf. The stop position of the platform is directly detected.

Therefore, the accuracy of the stop position of the lift platform between the parking rack on which the pallets are laterally transported and the lift platform is improved, and the lifting / lowering based on the expansion and contraction of the hanging rope due to the load fluctuation during the lateral transport of the pallets. The position change of the platform can be detected more reliably, and the level correction of the lift platform controlled by the level correction controller can be performed more reliably.

Here, it is possible to effectively prevent the generation of a step between the pallet horizontal transfer surfaces of the parking rack and the lift platform to which the pallets are transferred horizontally, and to facilitate the transfer of the pallets to each other.

In addition, since it is possible to effectively prevent the occurrence of a step between the pallet lateral transfer surfaces of both the parking shelf and the elevator, the pallet lateral transfer means needs to have a structure having a sufficient margin for the step. Therefore, the structure of the pallet lateral transfer means can be simplified.

Further, it is possible to effectively prevent the occurrence of a step between the pallet horizontal transfer surfaces of both the parking shelf and the lift platform to which the pallets are transferred laterally, and to extend and retract the suspended rope due to a load change during the pallet transfer. In addition, the level fluctuation of the lift platform can be corrected more reliably, and the influence of the expansion and contraction of the hanging rope can be limited to a minimum.
