  A rail 6 is laid on the traveling path of the transport carriage on the parking floor, and the transport carriage 4 rides on the rail 6 via a plurality of wheels 7 and travels along the rail 6. .

  The rail 6 has a discontinuous position between the elevating device 5 and the parking floor, and is not continuous over the entire travel range. For this reason, as shown in FIG. 15, the wheel 7 passes through the discontinuous portion 8 with the movement of the transport carriage 4, and the vibration when the wheel 7 passes through the discontinuous portion 8. Noise was generated by the impact.

  In Patent Document 1, a plurality of wheels 7 are provided to distribute the load, and the impact and vibration when each wheel 7 passes through the discontinuous portion 8 is reduced, and the generation of noise is prevented.

  However, a large load is acting on each wheel 7, and when passing through the discontinuous portion 8, the phenomenon of falling into the discontinuous portion 8 and then climbing onto the rail 6 is avoided. I can't. For this reason, noise cannot be completely prevented. Further, if the position of the wheel 7 is not sufficiently adjusted, or if the position shifts with time due to repeated impacts, large noise is generated.

By decelerating and stopping the rotation of the wheel 65, the conveyance carriage 21 can be braked.

  The conveyance carriage 21 is in a state of being floated through the air layer 60, traveling resistance is extremely small, and the driving force of the driving motor 71 may be small. Further, when the traveling slide 63 moves between the auxiliary traveling rails 58, 58, the traveling slide 63 moves in a floating state, so there is no physical contact and no noise is generated. The driving wheel 65 and the traveling wheel 66 are moved by rolling the joint between the auxiliary traveling rails 58 and 58, but the material of the driving wheel 65 and the traveling wheel 66 is soft, and the auxiliary traveling rail is used. The pressing force between the driving wheel 65 and the driving wheel 65 and the traveling wheel 66 only needs to obtain a traveling force and a braking force, so that it can be small and suppress the generation of noise.

  In addition, since there are a plurality of driving wheels 65, when one driving wheel 65 passes through the joint, the driving wheel 65 temporarily floats and power is not transmitted by the other driving wheel 65 even if the driving force is not transmitted. Then, the traveling of the transport carriage 21 is smoothly and reliably performed.

  Next, an operation when the vehicle 10 is stored will be described.

  For example, the case where the vehicle 10 enters the parking space 17a31 on the back side of the third floor underground from the entrance will be described. In this case, the warehousing path is such that the vehicle 10 enters the transport carriage 21 on the elevator 22 raised by the elevator 19, the elevator 19 descends to the third floor, and the fork of the elevator 19 The transport carriage 21 on which the vehicle 10 is placed (hereinafter referred to as a mounted transport carriage 21) is moved to an adjacent parking space 17a32 by the section (not shown), and the mounted transport carriage 21 is further self-running to Enter the parking space 17a31.

Is transmitted to the unit 76. The controller 76 closes the tenth on-off valve 41, stops the supply of compressed air to the air conduction path 27e, and maintains the supply of compressed air to the air conduction path 27a32 and the air conduction path 27a33.

  The control unit 76 issues a movement command to the mounted transport carriage 21 via the wireless communication unit 78. The cart wireless communication unit 82 receives a movement command, and the cart control unit 81 drives the drive motor 71 based on the movement command.

  When the mounted transport carriage 21 is self-propelled and enters the parking space 17a31, the sensor 49 confirms the completion of storage and the sensor 55 detects the absence of the mounted transport carriage 21 and transmits it to the control unit 76. To do. The controller 76 closes the third on-off valve 34 and the sixth on-off valve 37, and stops the supply of compressed air to the air conduction path 27a32 and the air conduction path 27a31. In the mounted conveyance carriage 21, the traveling slide 63 directly rides on the auxiliary traveling rail 58, and the loading state of the mounted conveyance carriage 21 is stable and reliable.
