It is supported so as to be able to move laterally, and can be switched between a position connected to the forward path 7 and a position connected to the backward path 8 by the cylinder/piston unit 42.
Although not shown in the drawings, these inter-route transfer devices 9 and 10 also transfer the incoming moving cart 6 to the cam driven roller 31 by moving the driven rollers 13 and 14 thereof.
Alternatively, a movable stopping cam that switches to an idle rotation position via 30 and automatically stops, and a drive means that switches this cam between an active position and a non-active position are provided.

Further, at the end portions of the outgoing path 7 and the incoming path 8, a movable stopping cam as described above and a drive means for switching the cam between an active position and a non-active position are provided.

To explain how to use it, a car 4 placed on the road surface 43 for carrying the car into the lifting and lowering conveyance device 2 is moved up and down by the lifting platform 2a of the lifting and lowering conveying device 2 and the running fork 2 provided on the lifting platform 2a.
b (having an engaging part that engages with a part of the automobile 4)
By the movement of the movement in and out, it is pulled onto the lifting platform 2a and sent out to the starting end position of the automobile conveyance path 1. At this time, one mobile cart 6 is located on the inter-route transfer device 9 and in a position connected to the outgoing route 7. Therefore, the car 4 sent out onto the car transport path 1 by the lifting and lowering transport device 2 has wheels 4a on one side thereof.
is sent out onto the floor surface 5, and the wheels 4 on the other side
b is delivered onto the moving carriage 6 on the inter-route transfer device 9. As shown in FIG. 3, the movable trolley 6 can be provided with a stopper 44 that can move in and out of the front and rear wheels that sandwich one of the supported front and rear wheels 4b.

As mentioned above, the wheels 4b of the automobile 4 are connected to the movable trolley 6.
Once supported at a predetermined position, the drive shaft 22 on the inter-route transfer device 9 is driven in the direction to send the moving trolley 6 to the outgoing route 7, that is, in the direction shown by the arrow 45a in FIG. The movable stopping cam that was acting on the cam driven roller 31 is returned to the non-acting position, and both the front and rear driven rollers 13 and 14 are moved to the drive shaft 22.
By returning to the driven position diagonal to
arrow 45b so as to move onto the guide rail 17 of
is forced to move forward in the direction.

The drive shaft 20 of the forward route 7 is indicated by the arrow 45a in FIG.
Therefore, the driven rollers 13 and 14 of the movable trolley 6 come into pressure contact with the drive shaft 20, so that the movable trolley 6 continues to move forward along the outbound path 7 in the direction of the arrow 45b. As the mobile trolley 6 supporting the wheels 4b of the automobile 4 moves forward on the outgoing route 7 in this way, the automobile 4 is moved onto the mobile trolley with one wheel 4a rolling on the floor surface 5. 6 and the car transport path 1
move.

When the movable trolley 6 reaches the end of the forward path 7, the movable stop cam switches the front and rear driven rollers 13, 14 to the idle rotation position via the forward cam driven roller 30, so that the movable trolley 6 has no relation to the rotation of the drive shaft 20. It will stop automatically without any problem. When the following movable dolly 6 collides with the movable dolly 6 that has stopped at the end of the outgoing route 7,
The front end bumper 15 of the following movable cart 6 moves backward against the spring 32, and the interlocking rods 34, 29
Since both the front and rear driven rollers 13, 14 are switched to the idle rotation position via the following, the following movable trolley 6 is also automatically stopped. Due to this effect,
Each of the movable carts 6 that tow and transport the automobile 4 via one wheel 4b can be automatically stored on the outgoing route 7.

Mobile trolley 6 stopped at the end of outgoing route 7
In this case, while the inter-route transfer device 10 is in the position where it connects to the outgoing route 7, the movable stopping cam that stops the moving trolley 6 is switched to the non-operating position and the driven rollers 13 and 14 are moved. By returning to the original driven posture, it can be transferred onto the guide rail 19 of the inter-route transfer device 10. At this time, the drive shaft 22 of the inter-route transfer device 10 is
It is being driven in the a direction.

When the automobile 4 is sent to a position on the inter-route transfer device 10, the movable stop cam on the device 10 switches the driven rollers 13 and 14 to the idle rotation position via the forward cam driven roller 30,
The moving cart 6 is automatically stopped at a predetermined position on the inter-route transfer device 10. Next, due to the vertical movement of the lifting platform 3a of the lifting conveyance device 3 and the movement of the running fork 3b (having an engaging part that engages with a part of the car 4) provided on the lifting platform 3a,
The automobile 4 whose wheels 4b on one side are supported by the moving cart 6 on the inter-route transfer device 10 can be pulled onto the lifting platform 3a and sent out onto the automobile unloading path 46.

Empty mobile cart 6 after sending out the car 4
After moving the inter-route transfer device 10 laterally to a position where it connects to the going-out route 8, the rotational direction of the drive shaft 22 is reversed as shown by the arrow 47a, and at the same time it acts on the forward cam driven roller 30. The movable stopping cam is switched to the non-operating position and the driven roller 13,
14 is returned to the driven position, it moves backward in the direction of the arrow 47b, and transfers from the guide rail 19 of the inter-route transfer device 10 to the guide rail 18 of the return route 8. The drive shaft 21 of the return route 8 is indicated by the arrow 47
Since it is being driven in the direction a, the driven rollers 13 and 14 of the movable trolley 6 come into pressure contact with the drive shaft 21, thereby moving backward along the return route 8 in the direction of the arrow 47b.

In this way, the empty movable trolley 6 that moves backward on the backward route 8 has a stop movable cam that drives the driven rollers 13 and 14 via the reverse cam driven roller 31 at the end position of the backward route 8. Automatically stops by switching to free rotation position. In addition, the bumper 16 of the following moving cart 6 moves backward against the spring 33 due to the collision with the stopped moving cart 6, and as a result, the driven rollers 13 and 14 are moved to an idle position via the interlocking rods 37 and 29. Since it can be switched to , it will automatically stop and be stored.

The moving trolley 6 stored as described above on the outgoing route 8 transfers the inter-route transfer device 9 to the outgoing route 8.
While rotating the drive shaft 22 in the direction of the arrow 47a, the movable stopping cam that stops the leading movable trolley 6 is switched to the non-operating position, and the moving trolley 6 is By returning the driven rollers 13 and 14 to their original driven positions, the moving cart 6 can be transferred onto the guide rail 19 of the inter-route transfer device 9. The movable cart 6 transferred onto the inter-route transfer device 9 is moved by the stopping movable cam on the device 9 switching the driven rollers 13 and 14 to the idle rotation position via the backward cam driven roller 31. It is stopped at a predetermined position. Then, as explained at the beginning, when it is time to receive the automobile 4 sent out from the lifting and lowering conveyance device 2, the inter-route transfer device 9 moves it laterally to a position where it can be transferred to the outgoing route 7.

It should be noted that a movable stopping cam for stopping the movable trolley 6 can be provided also in the middle of the outgoing route 7, if necessary. Furthermore, although an embodiment has been shown in which the vehicle transport path 1 is provided underground or downstairs and the lifting and lowering conveyance devices 2 and 3 are arranged at the loading and unloading area of automobiles, the device of the present invention has a layout that does not use the lifting and lowering transportation devices 2 and 3. It can also be used.

The vehicle transport device of the present invention can be implemented and used as in the above embodiment, and has a floor surface that rotatably supports wheels on one left and right side of the vehicle, and a floor surface that rotatably supports wheels on one side of the left and right sides of the vehicle, and a floor surface that rotatably supports wheels on one side of the vehicle. The moving trolley is equipped with a moving trolley that supports wheels and pulls a car, and this moving trolley has an outgoing route in the car transport direction, an outgoing route arranged parallel to this outgoing route, and a moving trolley at both ends of both routes. In the endless circulation path formed by the disposed moving trolley route transfer device, the driven roller on the moving trolley side obliquely presses against the drive shaft supported on the moving route side. It is characterized by being self-propelled by the propulsion force generated by the vehicle, and being configured to be able to be stored.

According to the conveyance device of the present invention, unlike the conventional conveyance device that uses a slat conveyor instead of the moving cart, the timing of loading and unloading of cars at the entrance and exit of the car conveyance path can be controlled by the conveyor. Not only is it possible to load and unload cars at any time without the need for synchronization with the vehicle, but it is also highly safe because it can be loaded and unloaded while the mobile trolley is stopped.

In addition, it is easy to stop the transportation vehicle at a necessary location, and it also has a storage function, so workers can rely on the machine's ability to perform various tasks on vehicles on the transportation route. It can be done easily without getting stuck.

In the embodiment, the return route of the moving trolley was provided in the space between the floor surface that supports one wheel of the automobile and the outbound route, but this return route was provided between the floor surface and the outbound route. It may be provided on the opposite side to the certain side, or it may be provided below the outgoing route.
