An elevator room 6 for raising and lowering the vehicle is provided between the entry / exit room 2 and the traveling path 4.

[0005] Then, the vehicle is transferred to the floor of each of the truck 5 and the parking room 3 in a direction orthogonal to the traveling path 4, that is, the vehicle is transferred from the truck 5 to the parking room 3 or from the parking room 3. Conveyors 7 and 8 for transferring to the carriage 5 are provided respectively. The conveyor 7 of the carriage 5 and the conveyor 8 of the parking room 3 rotate synchronously.

The synchronous rotation will be described with reference to FIG. FIG. 7 shows a top view of the truck 5. The truck 5 travels on wheels 9 laid on the traveling path 4 by wheels 10 by the driving force of a truck driving device 11.

[0007] The base 12 of the carriage 5 is provided with a conveyor 7 along the longitudinal direction of the base 12, that is, a front conveyor 7a and a rear conveyor 7b. A movable frame 13 that moves in a direction orthogonal to the traveling path 4 is provided at a central portion of the base 12, and a power transmission roller 14 is provided at a side end of the movable frame 13 facing the parking room 3. It is provided rotatably. The power transmission roller 14 and the conveyor 7 of the carriage 5 are both rotated by a conveyor drive motor 15.

[0008] The base 12 has a power cylinder 15A composed of a ball screw and a motor for moving the movable frame 13 in a direction perpendicular to the traveling path 4, that is, to the parking room 3 side.
Is provided.

The conveyor 8 provided inside the parking room 3 is also composed of a front conveyor 8a and a rear conveyor 8b like the carriage 5 (see FIG. 8). A driven roller 16 is provided on the traveling path 4 side of the parking room 3 so as to interlock with the conveyor 8 of the parking room 3 (see FIG. 7).

The front wheels of the vehicle are naturally placed on the front conveyor 7a of the truck 5 and the front conveyor 8a of the parking room 3, and the rear wheels are placed on the rear conveyor 7b of the truck 5 and the rear conveyor 8b of the parking room 3. Is placed. The length of both rear conveyors 7b and 8b is longer than the front conveyors 7a and 8a (see the bogie 5 in FIG. 7) because the length of the vehicle is adjusted by the rear conveyors 7b and 8b.

Then, for example, when the vehicle enters the warehouse,
When the vehicle is mounted and the cart 5 reaches the target parking room 3,
The power cylinder 16 operates to move the movable frame 13 toward the target parking room 3. This allows the movable frame 13
The power transmission roller 14 provided at the side end of the vehicle abuts against the driven roller 16 of the parking room 3 and presses it.

When the power transmission roller 14 presses the driven roller 16, the drive motor 15 is operated to rotate the conveyor 7 of the carriage 5 and the power transmission roller 14, and the conveyor 8 of the parking room 3 is also driven by the driven roller 16. As a result, the vehicle on the trolley 4 is carried into the target parking room 3.

[0013]

In the prior art described above, the motive power of the truck is brought into contact with the conveyor of the parking room by pressing a power transmission roller provided on the truck against a driven roller interlocking with the conveyor of the parking room. However, the contact surface between the driven roller and the power transmission roller wears out and the contact surface slips as the device is used, and the power is not sufficiently transmitted to the parking room, which hinders the transfer of the vehicle. There was a risk of coming.

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and a surface of a driven roller of a parking room, which is in contact with a power transmission roller of a bogie, is machined so that a sliding surface does not occur. It is an object of the present invention to provide a conveyor driving mechanism for a parking room in a parking device in which power is transmitted reliably.

[0015]

SUMMARY OF THE INVENTION The present invention, as a means for solving the above-mentioned problems, comprises a plurality of parking rooms for storing and holding vehicles along a traveling path of a vehicle carrier truck on which the vehicles are mounted and travels. A conveyor for transferring a vehicle in a direction perpendicular to the traveling path is provided in the parking room and the vehicle transport vehicle so as to be connectable to each other, and the conveyor vehicle is pressed against a driven roller interlocking with the conveyor in the parking room. In a parking device provided with a power transmission roller for transmitting a driving force on the cart side, the driven roller is formed of an iron material, and the outer peripheral surface of the driven roller is subjected to knurling.

Further, the present invention is characterized in that the power transmission roller pressed against the driven roller is formed of synthetic rubber such as urethane rubber.

[0017]

The present invention has been configured as described above.
For example, if a bogie carrying a vehicle travels along a traveling path and stops in front of a loading / unloading entrance of a parking room for storing the vehicle, a power transmission roller of the bogie moves and presses against a driven roller of the parking room. Thereby, the same power as the power of the conveyor of the cart is transmitted to the driven rollers, the conveyor in the parking room rotates, and the vehicle mounted on the cart is transferred to the parking room. During the transfer of this vehicle, the driven roller and the power transmission roller are in close contact,
Since the driven roller is formed of an iron material and its outer peripheral surface is subjected to knurling, the outer peripheral surface of the driven roller is less likely to slip, so that it is possible to avoid slippage when the driven roller is in close contact.

Further, since the driven roller is formed of an iron material and its surface is knurled, and the power transmission roller is formed of synthetic rubber such as urethane rubber, the driven roller and the power transmission roller are formed. The friction at the time of close contact increases, and slip can be further avoided.

[0019]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. 7 and 8 are denoted by the same reference numerals, and description thereof will be omitted.

FIGS. 1 to 3 show the driven roller 16 of the parking room 3 with which the power transmission roller 14 (see FIG. 7) of the truck 5 abuts. The driven roller 16 is the parking room 3
It is rotatably mounted on a pedestal 18 fixed to a pedestal 17.

That is, the axis of the driven roller 16 is
19 is provided, and the rotary shaft 19 is supported by being inserted into a bearing 21 on a bracket 20 provided on the base 18.

The rotating shaft 19 of the driven roller 16 is provided with a ratchet wheel 22, and the pedestal 18 is provided with a stopper claw 23 which engages with the ratchet wheel 22. The ratchet wheel 22 is for preventing the conveyor 7 in the parking room 3 from rotating unexpectedly while the vehicle is mounted.

Stopper claw 23 from ratchet wheel 22
When the power transmission roller 14 of the carriage 5 contacts the driven roller 16, the release rod 24 is pressed by an opening bar 24 provided on the side of the roller 13.

Further, since the driven roller 16 is formed of an iron material and the outer peripheral surface thereof is knurled, that is, the notch 28 (see FIGS. 1 and 2) is formed on the outer peripheral surface of the driven roller 16, Can be reduced. Thereby, when the power transmission roller 14 comes into close contact with the driven roller 16, the friction increases and slipping can be avoided.

Further, joint members 25 are provided at both ends of the rotating shaft 19 of the driven roller 16, and this joint member
As shown in FIG. 4, a universal joint 26 is connected to the front conveyor 8a and the rear conveyor 8b of the parking room 3.
And the driven roller 16 are integrally connected.

Therefore, when the power transmission roller 14 comes into contact with the driven roller 16, the driving force of the power transmission roller 14 is transmitted from the driven roller 16 to the universal joint 26 via the joint member 25,
The power is transmitted to the front conveyor 8a and the rear conveyor 8b via the connecting rod 27 (see FIG. 5).

As described above, the universal joint 26 is used to connect the driven roller 16 and the conveyor 8 in the parking room 3 side when the height of the driven roller 16 and the conveyor 8 is adjusted.
This is in order to smoothly transmit the power on the parking room side in accordance with the height adjustment.

That is, in order to transfer the vehicle smoothly and to ensure the transmission of power, the height of the conveyor 7 on the truck 5 side and the height of the conveyor 8 on the parking room 3 side, and the height of the truck 5 It is necessary that the height of the power transmission roller 14 and the height of the driven roller 16 on the parking room 3 side correspond to each other.

However, since the respective heights are confirmed when the carriage 5 is carried into the building of the parking device, after the carriage 5 is carried in, the conveyor 8 of the parking room 3 and the driven The height of the roller 16 is adjusted. The trolley 5 is referenced because the trolley 5 runs on the rail 9 and cannot be adjusted in height.

For this reason, the height adjustment is performed when the truck 5 is carried into the traveling path 4 at the time of construction, and the driven roller of the parking room 3 is driven.
In the case where 16 is lower than the power transmission roller 14 of the carriage 5, as shown in FIG. 5, a liner 29 is interposed between the pedestal 18 of the driven roller 16 and the pedestal 17, so that the driven roller 16 is raised.

The front conveyor 8a and the rear conveyor 8b of the parking room 3 are connected to the front conveyor 7a and the rear conveyor 7b of the carriage 5.
If it is lower, as shown in FIG. 6, the front conveyor 8a and the rear conveyor 8b are raised by interposing a liner 29 between the conveyor mounting base 30 and the gantry 17 in the parking room 3.

When the liner 29 is interposed for height adjustment as described above, the height of the driven roller 16, the front conveyor 8a, and the rear conveyor 8b of the parking room 3 may be different due to the interposed liner 29. There is.

If the heights are different, the driven roller 16 and the conveyor 8
There is a possibility that the connecting member connecting the rollers does not rotate smoothly and the driving force is not transmitted from the driven roller 16 to the conveyor 8. In order to avoid this, the connecting member between the driven roller 16 of the parking room 3 and the conveyor 8 is a universal joint 26.

In the case of this embodiment, the power transmission roller 14 of the carriage 5 which is pressed against the driven roller 16 is formed of synthetic rubber such as urethane rubber. Thereby, the load on the driving of the carriage 5 is reduced. The knurled driven roller 16 and the power transmission roller 14 constitute a conveyor driving mechanism 31 (see FIG. 3) in the parking room.

The present invention is constructed as described above. For example, if the truck 5 on which the vehicle is mounted travels on the traveling path 4 and stops before the entrance of the parking room 3 for storing the vehicle. Then, the power transmission roller 14 of the carriage 5 moves and comes into pressure contact with the driven roller 16 of the parking room 3.

As a result, the same power as the power of the conveyor 7 of the truck 5 is transmitted to the driven roller 16, the conveyor 8 of the parking room 3 rotates, and the vehicle mounted on the truck 5 is transferred to the parking room 3. During this transfer, the driven roller 16 and the power transmission roller 16 are in close contact with each other, but the driven roller 16 is formed of an iron material,
Since the outer peripheral surface is subjected to knurling, the outer peripheral surface of the driven roller 16 becomes less slippery, and slippage during close contact can be avoided. Thus, the appropriate pressing force becomes appropriate, and the power can be transmitted reliably.

[0037]

As described above, according to the present invention, since the outer peripheral surface of the driven roller pressed by the power transmission roller is subjected to knurling, the outer peripheral surface of the driven roller becomes less slippery, and the driven roller and the power transmission roller are hardly slipped. Can be prevented from slipping when they come into close contact with each other, and power can be reliably transmitted by an appropriate pressing force.

Further, since the driven roller is formed of an iron material, the surface thereof is knurled, and the power transmission roller is formed of synthetic rubber such as urethane rubber, the driven roller and the power transmission roller are formed. Friction at the time of close contact is increased, and slip can be further avoided. This also allows power to be transmitted reliably.
