[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for turning a mechanical parking device provided with a turning device.

[0002]

2. Description of the Related Art As a typical example of a mechanical parking device provided with a turning device, a number of vehicle storage cages are suspended in a building, and a vehicle is mounted on each cage in a storage space. In a vertical circulation type parking device that holds and mechanically enters or exits from the entrance on the ground, a pallet is removably mounted on each cage, and the pallet is lifted by a vertical traverse swivel device provided in the pit. A turning device has been widely used recently.

FIGS. 2 to 6 show such a conventional apparatus.
This will be described with reference to FIG. FIG. 2 is a perspective view showing a cage frame, and FIG.
FIG. 4 is a perspective view showing the lifting / lowering traverse device, FIG. 4 is a view showing a state where the pallet is lifted from the cage frame by the vertical traverse device, and FIG. 5 is a center of the cage frame or the pallet (a core on the cage side) and a vertical traverse device. FIG. 6 is a view showing a mechanism for aligning the core of the apparatus, and FIG. 6 is an explanatory view of a turning operation.

When a cage frame 2 provided with a pallet 1 is stopped at a lowermost entrance position for carrying in and out of a vehicle,
First, the lifting frame 11 of the vertical traversing device 10 is moved to a position where one of the light beams of the photoelectric devices PHT1 and PHT2 of the horizontal frame 12 is blocked by the light shielding plates 3 and 4 provided on the back surface of the pallet 1 (the dashed line in FIG. Position).

At this time, the photoelectric devices PHT1 and PHT2
If both light beams are blocked by the light blocking plates 3 and 4,
Although the center of the pallet 1 and the center of the revolving frame 13 are substantially coincident with each other, if only one of the light beams of the photoelectric device PHT1 or PHT2 is blocked by the light shielding plates 3 and 4, the pallet 1 Center and swivel frame 1
3 is shifted in the left-right direction (the direction of circulation of the cage frame 2), so that the photoelectric devices PHT1 and PHT1 are shifted from each other.
2 moves the traversing frame 12 in a direction in which the light beams are blocked by the light shielding plates 3 and 4.
To stop and center the turn.

Then, the lifting frame 11 is further lifted, and the pallet 1 is lifted by the turning frame 13, and then the pallet 1 is turned by a required angle.

As described above, if a mechanism for rotating the pallet 1 to the center of rotation of the turning device in advance and then lifting the pallet 1 to perform the turning operation is provided, it is 180 degrees.
° Even if the pallet 1 is turned back on the cage frame 2, there is no problem that the mounting position of the pallet 1 is shifted with respect to the cage frame 2.

[0008]

However, in the case of such a pallet swivel device, when the position of the cage frame 2 which stops at the entrance / exit deviates from the core of the parking device (hereinafter referred to as a standing core), the cage is not moved. Since the pallet 1 turns based on the core, as shown in FIG. 6, extra space must be secured in advance so that the vehicle 30 mounted on the pallet 1 does not contact the wall of the building. No. That is,
Assuming that the turning radius of the vehicle 30 is R, the required clearance between the vehicle 30 and the wall is C, and the stop error of the cage frame 2 is M, the required width L in the tower is
_O is L _O = 2 × (R + C) + 2M.

The present invention has been made in view of the above points,
It is an object of the present invention to provide a method for turning a mechanical parking device that requires less space.

[0010]

According to the present invention, a pallet for mounting on a vehicle is detachably mounted on a cage frame, and a lifting / lowering traverse turning device provided with a lifting / lowering device, a traversing device, and a turning device is provided in a pit. After the turning center of the turning device is aligned with the center of the pallet by the traversing operation of the device, the pallet is lifted by the lifting device, and the pallet is turned by the turning device.
After traversing to the position of the standing core by the traversing device,
The pallet is turned by approximately 90 °, and the traversing operation of the traversing device returns the turning center of the turning device to the center of the pallet. 2.An overhanging object detection device is provided outside the cage frame.If the overhanging object detection device operates during the turning operation, it is traversed to the position of the standing core by the traversing device, and then Turn is restarted by the turning device. 3.
An overhanging object detection device is provided outside the cage frame.If the overhanging object detection device operates during the turning operation,

[0011]

With the above arrangement, even if the vehicle is offset on the pallet, the turning operation can be performed without any trouble.

[0012]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is an explanatory diagram showing a basic concept of the present invention, and FIG. 7 is a flowchart showing a procedure of the present invention.

In the present invention, as shown in FIG. 1, first, the turning center of the turning device (the initial state matches the standing core) is aligned with the center of the pallet (the center on the side of the cage frame). When the vehicle 30 placed on the pallet reaches a position where the vehicle 30 is likely to interfere with a wall of a building, the turning operation is temporarily stopped, and the turning center of the turning device is set to the initial state. When the vehicle 30 is no longer likely to interfere with the wall of the building, the turning center of the turning device is returned to the center of the pallet again to complete turning.

Hereinafter, the most basic operation will be described with reference to FIG. The stopping position of the landing cage frame varies depending on the situation at that time, and usually falls within ± 100 mm. Therefore, as in the conventional case, the turning center of the turning device is moved by the traversing device so as to match the center of the pallet. Lift. (Step 1)

Next, after turning about 45 ° by the turning device, the turning center of the turning device is returned to the standing center by the traversing device, and turned about 90 °. (Step 2)

Next, the turning center of the turning device is returned to the center of the pallet by the traversing device, and the pallet 1 is lowered onto the cage frame 2 by turning the pallet approximately 45 °, thereby completing the turning operation.
(Step 3)

In this manner, in a rotation area where the vehicle 30 or the like mounted on the pallet 1 is likely to interfere with the wall of the building, the pallet 1 turns on the basis of the standing core.
It does not matter if the stop position of the landing cage frame is offset to either side.

As shown in FIG. 8, in order to perform the entire turning operation more efficiently, the traversing operation and the turning operation can be performed in parallel.

That is, after the pallet 1 is lifted, the center of rotation is returned to the standing center by the traversing device, and the first 45
After turning 90 °, after turning 90 °, the last 45 ° turning is performed while returning the turning center to the center of the pallet, thereby shortening the operation time. (Steps 2 'and 3')

FIG. 9 is a plan view showing another embodiment of the present invention, and FIG. 10 is a flowchart showing the operation of the apparatus of the embodiment. In the figure, reference numerals 20 and 20 'denote photoelectric devices provided near the walls of the left and right buildings. The photoelectric devices include light projecting devices 21 and 21' and light receiving devices 22 and 22 '. 20a, 20'a are emitted toward the respective light receiving devices 22, 22 'along the walls of the building. That is, the pallet 1 is set by the photoelectric devices 20, 20 '.
It detects an object such as a vehicle that has protruded outward from above.

In such an apparatus, first, the pallet is lifted by moving the turning center of the turning device to the center of the pallet by the traversing device in the same manner as in the prior art, with respect to the landing cage frame. (Step 1)

Next, turning is started by the turning device.
When the photoelectric device 20 or 20 ′ detects a protrusion, the traversing device returns the turning center of the turning device to the standing core, restarts the turning operation, and makes a 180 ° turn.
(Step 2 ")

After turning by 180 °, the turning center is returned to the pallet center. If the photoelectric devices 20, 2 during the turn
If 0 ′ does not detect any overhang, it will be turned 180 ° with the turning center of the turning device aligned with the center of the pallet. Then, the pallet 1 is lowered onto the cage frame 2 to complete the turning operation. (Step 3 ")

Therefore, it can be seen that the required width L in the tower is L = 2 × (R + C) in any of the embodiments.
That is, it is not necessary to consider the size of 2M due to the stop error M of the cage.

[0025]

As described above, according to the present invention, even if the cage stops at a position deviating from the standing center, the vehicle or the like may collide with the wall of the building during the turn. That doesn't happen. In addition, it is not necessary to secure a dimension in the tower larger than necessary.
