BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a three-dimensional parking lot for automatically carrying out a vehicle, and more particularly, to a vehicle moving apparatus for directly transporting a vehicle.

Japanese Patent Laid-Open No. 2-279880 discloses a three-dimensional parking lot employing a moving device for mechanically carrying out a car in and out of a three-dimensional parking lot.

The moving device is arranged in a passageway for a plurality of parking spaces partitioned in the horizontal and vertical directions, and moves between the turntable provided in the passageway and each parking space.

In addition, this moving device is provided with a catcher which can travel on a parking space or a turntable.

The catcher is thinly designed to be able to sneak into the lower part of the vehicle from the front-rear direction of the vehicle.

Moreover, the catcher is provided with four pairs of port-shaped arms which can slide and grasp under four tires of an automobile.

Each arm is supported on the catcher axis so that one end thereof can rotate horizontally within a range of 90 degrees.

On one side of the other end of the arm, fork-shaped hooks are formed at regular intervals.

In addition, a groove having a width and a depth in which the hook tip of the arm can enter is formed in the bottom surface of the turntable or each parking compartment.

When the car on the turntable is moved to the parking space, the following process is performed.

First, the catcher is infiltrated between the turntable and the floor of the vehicle with the four pairs of arms closed.

Then, without catching only the catcher on the underside of the car, four pairs of arms are raised to the open height.

In this state, the four arms are rotated horizontally at an angle of 90 degrees to stop.

At this time, the hooks of each arm are oriented in a direction parallel to each tire.

Next, lower the catcher only until the hook tip of each arm is accommodated in the groove on the bottom of the turntable, and in this state, move each arm parallel to the front and rear wheels so that the hook of each arm enters directly under each tire. Then, raise the catcher only to the height that all the tires are slightly raised from the bottom of the turntable.

Finally, by retracting the catcher to the vehicle body while lifting the car, the work of moving the car is completed.

Next, the moving device is moved to the front of the empty parking room with the car on, and only the catcher equipped with the car is advanced into the parking space.

Advance the catcher into the parking space and lower only the catcher to land all tires of the car on the floor of the parking space.

At this time, the hook of each arm of the catcher is accommodated in the groove | channel of the parking compartment floor surface.

When the landing of the tire is completed, the paired arms are moved in parallel to each other in parallel with the lowered state, and the hooks of the arms are removed from the lower part of the tire.

Then, only the catcher is raised to the height necessary to close the arm, and then each arm is rotated at an angle of 90 degrees to accommodate the inside of the catcher.

Subsequently, only the catcher is lowered to retreat from the parking compartment to the mobile unit body.

When the car is taken out from the three-dimensional parking lot, only the receiving point and the delivery point of the car are different from those at the time of receipt, and the basic operation of the moving device is the same.

On the other hand, the start or stop of movement of each part is monitored by various sensors and automatically controlled by a controlled computer.

In the above-described mobile device, it is desired to shorten the time required for getting in and out of a car.

This is because the shortening of the operation time can provide the driver with a shortening of waiting time when the car is taken out of the parking lot, and for the manager of the parking lot, the shorter the entry / exit time of the car, the higher the utilization efficiency of the parking lot, and thus the operational benefit. Because it becomes.

However, there is a limit in maintaining the certainty and safety of the operation to speed up each operation speed of the above-described mobile device.

The present invention is to solve the above problems, an object of the present invention is to provide a vehicle moving device for a three-dimensional parking lot that can perform the entry and exit of the vehicle quickly and accurately by omitting a part of the operation by the moving device through a simple improvement. It is.

Hereinafter, the present invention will be described with reference to the accompanying drawings.

Overall structure of multi-level parking lot

9 is a plan view of the three-dimensional parking lot.

Referring to this figure, a plurality of parking spaces 11 in the horizontal and vertical directions are formed on both sides of the hangar 10 with the central passage 14 therebetween.

Each parking chamber 11 is recessed in the center as shown in FIG.

On both sides of the parking space 11, a pair of rails 12 and the bottom surface 13 which support and support the tire of an automobile are formed in each rail 12 outer side.

In addition, a turntable 30 for changing the direction of the vehicle is arranged to be rotatable toward the passage 14.

Similarly to the parking room 11, the center of the turntable 30 is also recessed, and a pair of rails 31 on both sides thereof and a bottom surface 32 on which an automobile tire is landed on the outside of each rail 31 are provided. Formed.

The parking surface floor 13 and the bottom surface 32 of the turntable 30 are recessed at equal intervals of the grooves 13a and 32a along the rails 12 and 13, respectively. .

In the passage 14, a lifting plate 40 having a length corresponding to the entire length of the passage 14 is arranged horizontally.

As shown in FIG. 8, the elevating member 40 is held in support pillars 15 which are installed on both sides of the passage 14, and are mounted at both ends thereof by a pulling operation of the rope 43. It is configured to move up and down.

The moving device 50 is mounted on the rail 41 of the elevating plate 40 via the wheel 61 so as to be capable of traveling.

8 is connected to the lower surface of the moving device 50 by integrally connecting a part of the rotary chain 43 which is rotatably wound in both directions of the lifting plate 40 in the forward direction and the reverse direction, and operates the forward and reverse rotation of the chain 43. By way of example, the mobile device 50 is driven by one embodiment, but the traveling means of the mobile device 50 is not limited to this, and various known means can be adopted.

However, in one embodiment of the present invention, the most important fact is that by controlling the braking of the elevating drive source of the elevating plate 40 and the driving drive source of the moving device 50 by a computer, the arbitrary parking room 11 and the turntable ( The moving device 50 is moved between 30).

1 illustrates a mobile device.

The moving device 50 includes a horizontal bogie 60 mounted on the rail 41 of the elevating plate 40 so as to be capable of traveling, and a catcher mounted on the horizontal bogie 60 and traveling in the orthogonal direction of the rail 41 ( 70).

The invention relates in particular to the improvement of the catcher 70.

Referring to FIG. 3, the horizontal bogie 60 has a recess in the center for accommodating the location.

Rails 62 are disposed on both upper surfaces of the recessed portions.

1 to 7, the catcher 70 is a rigid frame having the same overall length as the horizontal bogie 60, and is capable of lifting up and down the horizontal bogie 60 by the plurality of wheels 72. It is configured to be able to travel along the longitudinal direction of the horizontal bogie 60.

The catcher 70 is provided with four arms 80 to hold two front tires and two rear tires. These arms 80 are paired to hold the tires located on the left and right of the vehicle, and the rotational movement about the support shaft 92 and the sliding movement in the longitudinal direction of the catcher 70 are carried out in each pair unit. Can be controlled by

The wheel 72 of the catcher 70 is mounted on the rail 62 of the horizontal bogie 60.

The wheel 72 is attached eccentrically to the axle 73 supported across the catcher 70, as in FIG.

The catcher 70 is moved up and down by the eccentric one of the center of the wheel 72 and the center of the wheel 72 by the rotation operation of the axle 73.

As the rotation means of the axle 73, for example, as shown in Figs. 2 and 3, the common shaft 74 is disposed in the longitudinal direction of the catcher 70, and the common shaft 74 and each axle ( The worm gear 75 is attached to the intersection with the gear installed in 73, and the forward rotation of the electric motor 76 is arranged on the common shaft 74 so as to transmit the rotation of the electric machine 76 through the gear. And controlling the lifting and lowering of the catcher 70 relative to the horizontal bogie 60 by reverse rotation.

When the catcher 70 on the horizontal bogie 60 enters and retracts between the parking compartment 11 or the tentables 30, for example, a known feed such as a gear mechanism or a screw transfer mechanism by a combination of a rack and a pinion gear, and the like. A mechanism can be adopted.

The moving device 50 separately holds the left and right front wheels and the left and right rear wheels of the vehicle.

The rotary motion mechanism and the sliding mechanism of the arm 80 of a pair of right and left pairs (one pair up and down in FIG. 1) are the same, but the rotational movement and the sliding movement of the arm 80 of each pair are controlled individually.

As shown in FIGS. 5 and 6, the arm 80 has an L-shape in its entire shape, and a plurality of arms 80 are formed in the direction perpendicular to the free end of the arm 80 at the free end of the arm 80. The hooks 82 are arranged at regular intervals.

Each hook 82 is formed continuously in the horizontal part 82a, the inclination part 82b, and the extension part 82c.

The support shaft 83 penetrates the horizontal portion 82a of the hook 82 and is supported in a state allowing the vibration in the vertical direction about the support shaft 83 over a predetermined range.

Between the lower surface of the horizontal portion 82a of the hook 82 and the arm 80, a spring 85 for pushing the respective hook 82 in the upward direction is inserted.

One of the structural features of the arm 80 is that when the catcher 70 is in the lowered position relative to the horizontal bogie 60, the hooks 82 are each of the rails of the catcher 70 and the horizontal bogie 60. It is arranged at a height that does not collide with 71) and (62).

This is to enable the opening and closing operation of each arm 80 even when the catcher 70 is in the lowered state.

In addition, it is also preferable that the tip of the extension portion 82c of the hook 82 is rounded or a roller is attached so that the hook 82 can be smoothly penetrated into the lower part of the tire.

Referring to FIGS. 1 to 7, the sliding mechanism of the arm 80 will be described. The paired arms 80 respectively support the support shafts 92 between both ends of the lower fitting plate 91. It is rotatably supported through.

The wheel 93 provided on the lower portion of the lower fitting plate 90 is mounted on the rail 71 of the catcher 70.

As shown in FIG. 2 and FIG. 4, the chain 77c which is rotated by the driving force of the electric motor 78 is wound between the sprockets 77a and 77b provided in the side of the catcher 70. As shown in FIG.

The chain 77c is connected to a part of the lower fitting plate 90, and the pair of arms 80 can freely travel along the rails 71 by the forward rotation and the reverse rotation of the electric motor 78, respectively. .

And a sensor (not shown) which detects a tire contact is attached to the appropriate position on the inclined part 82b of the hook 82. As shown in FIG.

When a stop signal is generated to the electric motor 78 shown in FIG. 2 using the signal of this sensor, the sliding movement of the arm 80 is stopped when the hook 82 contacts the lower peripheral surface of the tire. I can do it.

Then, a sensor (not shown) for detecting the contact of the tire is attached to an appropriate position on the inclined portion 82b of the hook 982.

When a stop signal is generated to the electric motor 78 shown in FIG. 2 using the signal of this sensor, the sliding movement of the arm 80 is stopped when the hook 82 contacts the lower peripheral surface of the tire. I can do it.

As the sliding means of the arm 980, a known transfer mechanism such as a screw transfer mechanism can be adopted in addition to the above mechanism.

Referring to the rotational motion mechanism of each arm 80 illustrated in FIGS. 1 and 7, first, the paired arms 80 and the crosspiece 88 are connected by a ring 89, and the crossbars ( The rack 100, which is a straight gear connected to 88, is meshed with a gear of the motor 101 for rotational motion control.

The stopper 102 which regulates sliding of the crosspiece 100 is arrange | positioned in the middle of the rack 100. As shown in FIG.

Moreover, the arm 80 rotates horizontally about the support shaft 92 by the forward / reverse rotation operation of the electric motor 101.

Next, the grip operation and the landing operation of the tire by the catcher 70 will be described.

First, the case where the car on the turntable 30 is put into the parking room 11 is demonstrated.

When the vehicle enters the turntable 30 by the driver's driving, the moving device is left at a position opposite to the turntable 30, and the catcher 70 in the state in which all the arms 80 are closed inward is turned on the rail 62. Is moved from above to the rail 32 of the turntable 30 and sneak directly under the vehicle.

The mover previously proposed by the present inventors needed to raise the catcher in order to open the arm without colliding with the rail of the horizontal bogie when the catcher is infiltrated on the underside of the vehicle, but in the present invention, the catcher 70 is lifted. The paired arms 80 can be opened by rotating the paired arms 80 outward at an angle of 90 degrees without being raised.

After opening all arms 80, sliding each arm 80 toward the front end and the rear end of the car, the tip of each hook 82 will engage the lower circumferential surface of the tire as shown in FIG. I'm forced to go down.

The claw 82 pushed back is accommodated in the groove 32 formed in the bottom surface 32 of the turntable 30 to continue the parallel movement.

When the hook 82 is inserted into the lower portion of the tire 21, the sliding movement is stopped based on the contact information with the tire 21 as described above.

If the hook 82 is a stationary type that does not vibrate, it is necessary to lower the catcher 70 to a height at which the hook 82 is accommodated in the groove 32 before the arm 80 starts to move. In this case, the hook 82 is vibrated so that the hook 82 can be inserted into the lower portion of the tire 21 without lowering the catcher 70.

When the hook 82 is inserted into the lower portion of the tire 21, the catcher 70 is raised to slightly raise the automobile from the bottom surface 32.

Then, the catcher 70 on which the vehicle is mounted is retracted to the horizontal bogie 60.

When the moving device 50 receives the sleeper car 20 from the turntable 30, the moving device 50 moves to the empty parking room 11.

Next, when the moving device 50 arrives at the parking space 11, the catcher 70 on which the vehicle 20 is mounted moves forward toward the parking space 11.

At this time, the catcher 70 moves from the rail 62 of the horizontal bogie 60 to the rail 12 of the parking compartment 11 and automatically travels to the parking compartment 11.

When the vehicle 20 reaches a predetermined position in the parking compartment 11, the forwarding of the catcher 70 is stopped.

Then, when the catcher 70 is lowered, all the arms 80 are lowered as a result, and as a result, the tire lands on the bottom surface 13 of the parking compartment 11 and at the same time the hook 82 of the arm 80. Is received in the groove of the bottom surface 13.

In this state, when each arm 80 is slid in the proximal direction, the hook 82 is pulled out of the lower part of the tire 21 to receive the elasticity of the spring 85 and rise to the original height.

When the parallel movement of each arm 80 is completed, all the arms 80 shown in FIG. 1 are closed and the catcher 70 is retracted to the horizontal bogie 60.

As described above, the present invention can provide the following effects by constructing the arm hook so that the arm can be made to advance and applying the spring force in the direction in which the hook is raised.

First, since the hook is forcibly pushed down along the circumferential surface of the tire when the hook of the arm is inserted into the lower part of the tire, the operation of lowering the catcher can be omitted.

When the hook of the arm is pulled out from the lower part of the tire, the hook is raised due to the elasticity, so that the operation of raising the catcher can be omitted.

As a result, since a part of the operation of the mobile device can be omitted, such control is unnecessary, and the entry and exit of the vehicle can be performed quickly.

Finally, the amount of lifting and lowering of the catcher can be designed as much as the amount of vibration of the hook vibrating in the longitudinal direction.
