The rotary table device 10 includes a rotary table 30 supported rotatably about a vertical iliff axis, guide strips 40 and 41 arranged in parallel on the upper surface of the rotary table 30, and a detection board provided close to the rotary table 30. 6o, and a stop sensor 70 that detects the stop position of the vehicle, which is disposed on a part of the turntable 30 or on the ceiling.

Each part will be explained in detail below.

<Exit> Turntable The turntable 30 is rotatably supported and provided in the vicinity of the entrance/exit 20 of the parking lot facility.

This rotary table 30 rotates in conjunction with the detection plate 60.

The interlocking mechanism between the rotary table 30 and the detection plate 60 will be described later.

The turntable 30 is equipped with a pair of parallel guide strips 40, 41.

<C> Guide band The guide bands 40 and 41 are composed of a plurality of plates connected by bottles or a flat belt, and are connected between a pair of subrockets 42 or rollers disposed at the bottom of the rotary table 30, respectively. Approximately half of each guide strip 40 and 41 is exposed on the surface of the rotary table 30.

In FIG. 4, guide bands 40, 41 (not shown) are wound around the sprocket 42, and a pair of guide bands 40, 4
The rotation of the motor 44, which has been decelerated by the speed reducer 43, can be switched between idle and rotary drive by connecting and disconnecting the electromagnetic clutch 45. Normally, the pair of guide bands 40 and 41 move freely, and the rotation of the motor 44 is controlled by the speed reducer 43. Rotation begins when the front wheels are placed on the guide strips 40, 41.

Furthermore, wheel mooring means for mooring wheels is provided on the surface of each guide band 40, 41, respectively.

Since the wheel mooring means of each of the guide strips 40 and 41 have the same structure, the wheel mooring means of one of the guide strips 40 will be explained based on FIG. The provided front roller 46, the rear stopper 47 located behind the front roller 46, and these members 40, 4
7, and a support roller 48 located between the rollers 7 and 7.

The front roller 46 and the support roller 48 are installed in a loose state and have the function of preventing the front wheels of a front wheel drive vehicle from running over, for example, and the rear stopper 47 has the function of locking the front wheels.

Detection board The detection board 60 is a device that automatically determines the midpoint position of each tread of the front and rear wheels of the vehicle and controls the rotation of the rotary table 30.

An example of the detection 160 will be explained based on FIGS. 1 and 2. The detection board 60 consists of a large number of treadles 6 installed parallel to the direction in which the vehicle passes.
1, a spring member 62 that elastically supports each footboard 61,
It consists of a limit switch 63 that electrically detects the presence or absence of wheels.

That is, two spaces are recessed in front of the rotary table 30, a large number of treads 61 are housed in each space at equal pitches, and a spring member 62 is interposed between each tread 61 and the shelf. Treadboard 6
A limit switch 63 is disposed at the bottom of 1.

The pitch of the tread plate 61 is preferably about 20+am in consideration of strength, detection performance, etc.《Also, the total length of the tread plate 61 should be set to, for example, 1600~20 am to prevent the front and rear wheels from riding at the same time.
Approximately 2000 mm is preferable.

The forming width of each group of tread plates 61 shall be sufficient to accommodate many vehicle models with different wheel widths, and may be divided into two groups as in this embodiment, or these may be connected consecutively. and form a group.

<E> In order for the vehicle-centered detection means detection board 60 to determine the midpoint raP of each wheel width of the front or rear wheels as shown in FIG. A computer is connected, and this computer is connected to the driving part of the turntable 30, and the intermediate point is determined based on the detection signal of the outermost or innermost of the plurality of limit switches 63 that detect the presence of a wheel. There is a method of determining the midpoint position P.

Rotation No. 30 is controlled to rotate until a point Q on the peripheral edge passing through the center line C1 of the rotary table 30 coincides with the determined midpoint position P.

In addition, the means for determining the midpoint position P and the $il! that makes the point Q follow the midpoint position P! Of course, many known means can be used as the control means.

<effect Next, the operation of the rotary table device 10 will be explained.

<A> Detection of front wheels As shown in FIG. 1, before the vehicle gets onto the detection board 60, the center 1&lIcl of the rotary table 30 coincides with the center of the detection board 60.

In FIG. 5, when the vehicle moves forward toward the turntable 30,
The driving wheels A and A' step onto the detection panel 6o.

For a driver with unskilled driving skills, it would be troublesome to drive the front wheels A, A' directly onto the guide strips 40, 41;
Even an inexperienced driver can easily step into the wide detection panel 60.

For example, as shown in FIG. 6, one front wheel A is stepping on some of the tread plates 61c to 61f, and the other front wheel A' is stepping on some of the tread plates 61d to 61g'. 9 also detects the outermost or innermost depression position.

In the case of FIG. 6, front wheel A. The midpoint position P between A' is the footboard 61
One detection board 60 is moved from its original position by half the pitch of
It is automatically determined that the object is moving to the side.

<Exposure> When the movement of the rotation midpoint iP of the rotary table is detected, the rotary table 30 is rotated counterclockwise until the point Q of the rotary table matches the midpoint position fffP, as shown by the arrow in FIG. do.

Front wheel A. When A' passes the detection board 60, the group of tread plates 61 that had been lowered returns to its original height.

<C> Entering the front wheels As mentioned above, when the front wheels Δ and A′ pass the detection plate 60, the guide strips 40 and 41 are automatically placed on the advancing side of the front wheels A and A′.
Control is completed so that one end of is located.

Therefore, as shown in FIG. 7, if the driver continues to drive the front wheels of the vehicle, the front wheels A. A' will surely enter the guide bands 40 and 41.

As a result, the front wheels A and A' are connected to the front opening 46 in Figs. 2 and 3.
Even if it is placed on the support roller 48 and driven, it simply rotates idly and does not get over the front roller 46.

(2) Forced movement of the vehicle After the driver places the front wheels A and A' on the front rollers 46 and support rollers 48, the driver turns off the engine, shifts to a low gear, and gets off the driver's seat.

When it is confirmed that the driver has exited the vehicle, the guide bands 40 and 41, which have been in an idle state until then, rotate.

When the guide bands 40 and 41 rotate, the rear stopper 47 engages the rear portions of the front wheels A and A', so that the vehicle is forcibly moved forward.

<Po> Rear wheel detection When the vehicle continues to move being towed by the rear stoppers 47 of the guide bands 40 and 41, the rear wheels B. B' passes through the detection board 60.

At this time, the rotating body 30 is automatically rotated in a direction in which the guide bands 40 and 41 are located on the advancing side of the rear wheels B and B' in the same process as in the case of the front wheels A and A' described above.

<Go> When the rear wheels B, B'' cross the detection board 60, the rear wheels B,
The alignment of the guide strip 40.4.1 on the traveling side of B' has been completed.

Therefore, the rear wheels B and B' inevitably ride on the guide strips 40 and 41.

In this way, the rotating table 30 rotates between the front wheels A, A' and the rear wheels B, B.
Since it rotates according to the advancing position of ', the rotating platform 3 of the vehicle
No advanced driving skills are required to get into the vehicle.

<G> When the vehicle stops moving, the front wheels A. Following the entry of A', rear wheel B,
When the entry of B' is completed, the turntable 30 rotates until it aligns with the center line of the entrance/exit 20 of the parking lot.

When the front end of the vehicle being pulled by the guide strips 40 and 41 reaches the installation position of the stop sensor 70, the stop sensor 70 detects the vehicle, and as a result, the guide strips 40 and 41
4l stops rotating.

After the vehicle is stopped, the vehicle is moved into and out of the warehouse 120 by a transport device (not shown) or by the driver, for example.

<Other Embodiments> In the embodiments described above, the case where a front wheel drive type vehicle is moved forward and the rotary table device is entered is explained.
If the vehicle is a rear wheel drive type, you may enter the vehicle with the rear wheels first.

Furthermore, even if the vehicle is a rear wheel drive vehicle, if the front and rear wheels are maintained in an idle state using the driving force of the rear wheels until they enter the pair of guide strips 40 and 41, and then rotated. ,
It is also possible to enter from the front wheel side.

<Effects of the Present Invention> Since the present invention is as explained above, the following effects are provided.

<B> The guide band can be rotated in accordance with the riding position of the front and rear wheels by the interlocking operation of the rotary table and the detection board.

Therefore, even an inexperienced driver can easily drive the vehicle along the center line of the turntable.

<Exposure> Since the entry position of the vehicle is accurate, it is possible to prevent collisions and personal injury accidents that would otherwise occur due to the rotation of the vehicle.

<C> In the conventional turntable, the direction of vehicle entry is limited to one direction.

In contrast, in the present invention, the center line of the turntable can be moved to an arbitrary position, which is advantageous when designing a parking lot.

(2) Even if the overall length of the vehicle is different, the final stopping position on the rotary table is accurate.

Therefore, it is suitable for use not only in general parking lots but also in automatic parking lots where parking and exit operations are automated.

<E> The detection panel that detects the entry position of vehicles is buried in the floor, so it does not obstruct the passage of vehicles or people.

<F> In the case of a front-wheel drive type vehicle, this can prevent the vehicle from running out of control if the accelerator is accidentally stepped on after the front wheels have been placed on the rotating platform.
