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

For example, in the flat reciprocating parking system, a movement passage is formed between storage rooms provided on one side or both sides, so that the trolley 10 on which the vehicle is mounted moves in the lateral and longitudinal directions, respectively, so that warehousing and warehousing is performed.

A plurality of roller conveyors 11 are arranged at regular intervals on the bogie 10 or on a fixed pallet (not shown) installed on the floor of the storage room to move the vehicle in the warehousing or warehousing direction, and the roller conveyor 11 A driving means is provided to drive them.

The roller conveyors 11 are driven, for example, by connecting a power transmission means (not shown) consisting of a chain and sprocket with the power of a motor mounted on a bogie to rotate each roller conveyor 11 in a forward or reverse direction to move upwards therefrom. Mounted vehicles can be moved.

In addition, as a means for driving the roller conveyors of the fixed pallets provided in the storage room, the driving friction wheels 12 of the bogie 10 are provided so that the bogie 10 is moved toward the fixed pallet, and another provided at the tip of the fixed pallet. Power is transmitted by contact with a driven friction vehicle (not shown), and the roller conveyors provided on the truck 10 and the fixed pallet rotate in the same direction, respectively, so that the vehicle can be put into or out of the vehicle.

The bogie 10 is driven by a transverse motor 2 mounted thereon and a longitudinal motor (not shown), and rotates the wheel in contact with the rail to move forward and backward between the lift that goes up and down at the entrance of the parking lot and each storage room. It is common to be configured to be movable in the direction or the left and right longitudinal directions, respectively.

The present invention is to ensure that the vehicle can always be moved in a straight line without being crooked during the shipping process by aligning the tire position in a straight state in a state mounted on a roller conveyor of a bogie for parking a vehicle in a parking machine without a driver. It is characterized.

That is, a pair of left and right operating members 20 are installed on the bogie 10 toward the tire 1 in a state where the vehicle is seated on the top by driving the roller conveyor 11 .

The operating member 20 is installed parallel to the moving direction of the vehicle in a bar shape, and is installed at the front and rear wheels of the vehicle, respectively, as shown in FIGS. 1 and 2 .

Support members 30 are positioned side by side on the outside of the operating member 20, and springs 31 are elastically installed therebetween.

11 is an enlarged view showing a state in which a coiled spring 31 is elastically installed between the operating member 20 and the supporting member 30.

Therefore, as will be described later, when the support member 30 or the ball casters 32 attached to the outside of the support member 30 contact the tire 1 of the vehicle by the operation of the slide means 40, it plays a buffering role. By doing this, damage to the tire 1 or the ball casters 32 can be prevented.

Then, the operating member 20 installed in parallel with the support member 30 is moved forward and backward by the operation of the slide means 40, respectively.

8 to 10 show an embodiment of the slide means 40 according to the present invention.

That is, a gear 41 is installed on the rotating shaft of the drive motor M, and the gear 41 and the pinion 42 are geared together so that the drive is performed in a state in which they are engaged with each other.

In addition, a rack part 44 is provided on the bottom surface of a pair of left and right rods 43 coupled in a right angle direction toward the operating member 20, respectively, to engage the gear 41 and the gear 41 to rotate The pinion 42 and the rack portion 44 of the rod 43 are geared together.

Therefore, the gear 41 and the pinion 42 are rotated in the meshing direction according to the rotation direction of the drive motor M, and thus the rod 43 geared through the rack 44 moves in a straight line to the tire 1 ), or slide movement can be made symmetrically toward the inner center.

10 shows that two rods 43 are installed side by side in a state in which the gear 41 and the pinion 42 are engaged with each other while maintaining a distance from each other toward the tires 1 on both sides, so that the slide drive is symmetrical to each other. Possible arrangements are shown.

In this way, when the rod 43, the operating member 20, and the support member 30 are driven toward the tire 1, when both tires 1 are distorted, a plurality of attached to the support member 30 at regular intervals The ball casters 32 are aligned to maintain a straight line while pressurizing the tire 1.

Here, it is okay to install the rods 43 one at a time on the left and right toward the center of the tire 1, but as shown in the drawing, it is stable to install a plurality of rods 43 while maintaining a distance in the front and rear positions of the tire 1. It is preferable in terms of the effect of aligning the tire 1 with

In addition, in general, the steering direction of a vehicle is determined by the front wheels.

Therefore, it is okay to install the tire aligning device of the present invention only at the front wheel position of the vehicle, but as shown in FIGS. 1 and 2, in order to stably align all four tires 1, each of the front and rear tire 1 positions are shown. It should be noted that it is desirable to install the alignment device of the invention.

On the other hand, in order to guide the stable linear motion of the rods 43, as shown in FIG. 9, a plurality of guide members 71 are fixed to the lower part of the top plate 70, and between the rods 43 and the guide member 71 It is preferable to install a linear bearing 72 for guiding linear movement.

In addition, when a plurality of rods 43 are installed on both the front and rear sides of the tire 1, as shown in FIG. 3, the two pinions 42 installed at a distance are connected by a shaft 45 and driven. The rotational force of the motor M is transmitted, respectively, so that the rods 43 on both sides can be operated simultaneously.

In addition, the slide means 40 may be formed of electric actuators (not shown) -electric actuators- installed in a direction perpendicular to the operating member 20 and moved forward and backward by an electric signal.

A plurality of ball casters 32 are attached to the outside of the support member 30 at regular intervals so that the operation member 20 and the support member 30 move toward the tire 1 by the operation of the slide means 40. When opened, the ball casters 32 contact the inner surface of the tire 1.

Therefore, damage to the tire 1 can be prevented.

The ball caster 32 is a type of bearing in which spherical balls are accommodated inside the housing, and prevents noise, shock, or damage to the contact surface even when they slide with each other while being in contact with an object in contact with a non-directional rolling motion. Since it is widely known on the market, a detailed configuration and effect description will be omitted.

In addition, a limit switch 50 is installed on the operation member 20 to detect movement of the support member 30 in contact with the tire 1 while being elastically supported by the spring 31 .

Therefore, when the ball casters 32 come into contact with the tire 1 as the support member 30 spreads toward the tire 1 together with the operating member 20 connected to the rod 43 by the operation of the slide means 40 The distance between the support member 30 and the operating member 20 is narrowed by the spring 31, and at this time, the limit switch 50 is detected to stop the operation of the driving motor M.

Therefore, when the support member 30 and the ball casters 32 contact the tire 1 excessively, failure occurs or damage to the tire 1 or its components can be prevented.

In addition, the shock absorbing role of the spring 31 prevents damage to the contact surface in the process of aligning the tire 1 .

On the other hand, the bogie 10 is provided with a position sensor 60 for detecting whether or not the vehicle is mounted.

Therefore, after the position sensor 60 detects that the vehicle is mounted on the bogie 10, the drive motor M is operated to spread the rod 43, the operating member 20, and the support member 30 apart. It returns after aligning the tire 1 while operating.

As described above, the tire 1 is aligned in a straight state while being mounted on the bogie 10 to be seated in the storage room of the parking facility by the tire aligning device of the present invention, and then stored on the pallet for storage.

In addition, since the tires maintain alignment during the delivery process, it is possible to ship the vehicle in a safe state without damaging the vehicle or colliding with the parking facility in a straight line.
