The operation of the above embodiment will be described below. In the vehicle shipping line 10, the inspection unit roller conveyor 12 and the unloading unit roller conveyor 13 are continuously driven in synchronization. That is, each motor 44, 4
When each of the conveyors 5 is driven, as shown in FIG. 10, the support shaft 20a located at the end of each of the one conveyor unit 12A, 13A and the other conveyor unit 12B, 13B in the transport direction rotates to one side. At the same time, the sprocket 24 at the end is rotated to one side. This allows
The chain 28 rotates and the sprocket 25 at the start end rotates to one side, and the intermediate sprocket 27 rotates to the other, and the rollers 22 at the intermediate part together with the intermediate sprocket 27 rotate to the other.

At this time, the roller 22 at the end in the transport direction is
a and the support shaft 20a are cut off via the bearings 21 and 23, so that the roller 22a at the terminal end does not rotate with the support shaft 20a, and
Rotated in the same direction as the other. That is, at the end portion in the transport direction, the rotation of the roller 22 in the intermediate portion to the other side causes the sprocket 32 for supplying the rotational force to rotate to the other side and the sub-chain 33 to rotate. Sprocket 31 is rotated to the other side.
Thereby, as described above, the roller 22a at the end in the transport direction is also rotated to the other side.

Similarly, at the start end portion in the transport direction, the intermediate roller 22 is rotated to the other side, so that the rotational force supply sprocket 38 is rotated to the other side and the sub-chain 39 is rotated. The rotating sprocket 37 is rotated to the other. Thereby, the attached roller 35 is also rotated to the other side. As described above, since each of the rollers 22, 22a and the attached roller 35 are both rotated to the other, the truck 1 is transported by the conveyors 12, 13 to the vehicle shipping line 10.
It is sequentially conveyed to the terminal side above. The loading unit roller conveyor 11, which can be driven synchronously or stopped, operates in the same manner when driven.

When the truck 1 is loaded on the vehicle shipping line 10, the loading unit roller conveyor 1 is driven by the motor 43.
1 is stopped. Therefore, the truck 1 that has been moved forward moves the left and right wheels 3 and 4 to both conveyor sections 11A,
In a state of being distributed to 11B, the vehicle runs on the group of rollers 22, 22a.

In this way, the loading unit roller conveyor 1
After the vehicle 1 is loaded with the truck 1, the driver locks the rear wheels 4 with the side brakes and gets off the vehicle. Then, the driver presses the conveyor start button, and drives the carry-in roller conveyor 11 by the motor 43. The drive of the loading unit roller conveyor 11 is performed in synchronization with the continuously driven inspection unit roller conveyor 12, so that the track 1 on the loading unit roller conveyor 11 is moved to the inspection unit roller conveyor 12.
It is carried up.

As described above, the inspection unit roller conveyor 12
The truck 1 carried out is transported on the vehicle shipping line 10 by the continuous drive of the inspection unit roller conveyor 12. At this time, the rollers of the two conveyor sections 12A and 12B of the inspection section roller conveyor 12, that is, the two rows of right and left rollers 22, 22a, 22, 22a are arranged as shown in FIGS. 1, 2, 11, and 12. , Viewed from the transport direction,
Since the center side in the left-right direction is arranged in a lower inverted C-shape, even when the truck 1 is displaced in the left-right direction or leans front-to-back and left-right when entering the carry-in roller conveyor 11, During this conveyance, the posture is automatically corrected, so that the inspection unit roller conveyor 12 does not meander, and is conveyed in a correctly supported state.

The angle of inclination for automatic posture correction varies depending on the weight of the vehicle, the wheel width, etc., but the height adjuster 1 is designed to have an inverted C-shape suitable for a plurality of vehicle types.
6 are set and adjusted.

Track 1 whose attitude has been corrected as described above
Is transported in the car wash zone 60, and the wax and dust applied to the truck 1 are removed by the car wash device 62 provided in the car wash zone 60. At this time, the truck 1 is transported in a state of being correctly supported without meandering, so that cleaning can be performed easily and suitably. And
For example, due to a shift in the contact timing of the left and right side brushes in the car washing device 62, a contact pressure precedes one side of the truck 1, and the truck 1 tries to slide to the other side, that is, to the left and right.

At this time, the right and left two rows of rollers 22,
Since the outer surfaces of the groups a, 22 and 22a are formed on the uneven surface 50 for slip prevention by the group of rectangular rods 53,
The contact portions of the wheels 3, 4 are deformed so as to conform to the uneven surface 50, and the contact area is enlarged. Therefore, the skid is prevented by the frictional resistance due to the enlarged contact area.

Further, since the uneven surface 50 is formed at three positions (a plurality of positions) in the direction along the roller axis 52 and the rectangular bars 53 are arranged in a staggered manner, the interval in the left-right direction is reduced. By setting according to a plurality of types of wheel intervals and wheel widths, the end surface of the rectangular bar 53 in the left-right direction is set to the wheels 3,
The side surfaces of the wheels 3, 4 which are opposed to the side surfaces of the wheels 4 and are about to move laterally due to skidding are received by the end surfaces of the rectangular rods 53, so that skidding is more reliably prevented.

In this manner, the wax, dust and the like applied to the truck 1 are washed and removed by the car washing device 62. At this time, the washing water is applied to the rollers 22, 22a.
The washing water is not brought to the end of the line because it is dropped through the gap between the ends, and the outlet at the end is not flooded.

As described above, the truck 1 transported in the car wash zone 60 enters the inspection zone 61. In the inspection zone 61, a final check is made as to whether the equipment of the truck 1 to be shipped is complete, and a worker who has performed the check or another worker gets into the driver's seat of the truck 1. The track 1 is moved from the inspection roller conveyor 12 to the inspection roller conveyor 1.
The truck 1 is conveyed to the unloading roller conveyor 13 that is driven synchronously with the unloading unit 2, and is unloaded from the unloading roller conveyor 13. Shipped from line 10.

As described above, by using the roller conveyors 11, 12, and 13 in the vehicle shipping line 10, when the roller conveyors 11, 12, and 13 are installed on the floor 6,
A return path like a slat conveyor is not required, so the whole can be made bulky and small, installation and repair work can be performed easily, and equipment costs can be reduced, and cleaning under the conveyor can be performed easily. .

Further, as shown in FIG.
The lower moving path portion is positioned at a high level with respect to the floor surface 6 because the lower moving path portion is meshed with the upper portion of the intermediate sprocket 27. Therefore, foreign matters such as sand and water accumulated on the floor surface 6 Is prevented from adhering to the lower moving path, and the roller conveyors 11, 12, and 13 are formed to have a lower overall height.

Next, another embodiment of the present invention will be described with reference to FIG.
It will be described based on. That is, the uneven surface 50 for slip prevention
The roller shaft center 5
2 is provided. The concave grooves 55 are formed at a plurality of positions in the circumferential direction of the roller outer surface 51 at predetermined angles. The uneven surface 50 is formed by each roller 2
The outer surfaces 2 and 22a are formed at three (plural) locations in the direction along the roller axis 52. At this time, the middle uneven surface 50 is in the concave groove
5 are displaced in the circumferential direction, and thus are arranged in a staggered manner between adjacent ones.

Next, still another embodiment of the present invention will be described.
A description will be given based on FIGS. That is, two rows of left and right rollers 22, 22a, 22, 2 are arranged in a lower inverted C-shape at the center in the left-right direction when viewed from the transport direction.
No uneven surface for slip prevention is formed on the outer surface of group 2a.

In this case, the rollers of the two conveyor sections 12A and 12B in the inspection section roller conveyor 12, that is, the two rows of right and left rollers 22, 22a, 22 and 22a are positioned lower in the center in the left and right direction when viewed from the transport direction. By being arranged in a reverse U-shape, even if the truck 1 is shifted in the left-right direction or inclined in the front-rear direction and left-right direction when the vehicle 1 enters the loading unit roller conveyor 11, the truck 1 is automatically moved during this conveyance. The posture is corrected, so that the sheet is conveyed in the inspection unit roller conveyor 12 without being meandering and being properly supported.

In each of the above-described embodiments, the rollers of the two conveyor sections 12A and 12B in the inspection section roller conveyor 12, that is, the two rows of right and left rollers 22, 22a, 22,
The group 22a is arranged in a lower inverted-C shape on the center side in the left-right direction when viewed from the transport direction. You may.

In the above-described embodiment, the truck 1 is shown as a vehicle to be processed, but this is a normal passenger car or a light car (wheels are indicated by phantom lines in FIGS. 1, 11 and 14). Can be processed, and a plurality of vehicle types can be processed at random.
