Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a vehicle transport platform used for painting the bottom surface of a vehicle such as an automobile, and a vehicle transport device using the same.

BACKGROUND OF THE INVENTION Generally, on an automobile production line, the bottom surface of an assembled automobile body is sometimes further coated with anti-rust coating as a special specification. This is to prevent the bottom surface of the car body from being corroded by anti-freeze agents etc. sprayed on the road surface during the winter in, for example, cold regions. Conventionally, when applying this type of anti-rust coating, a conveyor was placed on both sides of the opening of the painting bit in the factory, and a large number of slats were placed on the endless drive chain on which the wheels of the car were placed. They were attached directly at predetermined intervals and inwardly protruding.

However, with this, the slat mounting part of the endless drive chino needs to be strong enough to support the load of the car, and the slat mounting part, which is subject to such a large load, is easily damaged, and it is necessary to In order to pull and rotate a drive chain having a drive chain, the conveyor has to be very large, which causes problems in that it is not only complicated and costly to manufacture, but also requires a large installation space.

Note that a vehicle loading mechanism (20) similar to that of the first embodiment is arranged at the starting end of the accumulation line (41), and a vehicle unloading mechanism (30) is a short one extending from the drying line (43). It is located at the end of the painted vehicle storage line (48).

Figures 7 and 8 show the accumulation line (2) of the vehicle to be painted (2).
41) to the painting line (42) in detail. In the figure, both left and right endless drive chains (5) (5) of the conveyor (40) of the accumulation line (41) are shown.
At the end of the rollers, a required number of drive rollers (49) are arranged in two rows on the left and right at required intervals on an extension line of these rollers.

The drive rollers (49) in each row are attached to a pair of left and right frames (SO), respectively. Note that illustration of driving means for these driving rollers (49) is omitted.

On the other hand, at the starting ends of the endless drive chains (5) (5) of the conveyor (4) of the painting line (42), drive rollers (49) are installed at predetermined intervals on the extension line of these. They are arranged in two rows.

The first transfer conveyor (46) is arranged at right angles to the transfer conveyor (40) of the accumulation line (41) and the transfer conveyor (4) of the painting line (42). A pair of endless drive chinos (51) (51) in front and rear of
) can be raised and lowered freely. Drive roller (
Both left and right frames (50) (5G
) are provided with recesses (53) (53) for letting these endless drive chinos (51) (51) escape.

In the above, the transport conveyor (4) of the accumulation line (41)
A vehicle carrier (1) loaded with a car (2) is placed at the end of the vehicle (1).
0), the fluid pressure cylinders (52) (52) are activated to raise the front and rear endless drive chains (51H51) of the first transfer conveyor (46), and move them to the transfer conveyor (40) and these The drive roller (
49) Protrude upward from the upper end of (49). As a result, the vehicle transfer platform (10) is now moved to the endless drive chino (51).
) (51) to the right and reaches the starting end of the conveyor (4) of the coating line (42). Therefore, the fluid pressure cylinder (52H52) is operated to lower the endless drive chains (51) (51) of the first transfer conveyor (46), and move them to the transport conveyor (4) and the drive roller (49) on the extension line thereof. (49) Recess below the upper end. As a result, the vehicle carrier (10) is transported by the transport conveyor (4) of the painting line (42), and while it moves above the painting bits (3), the loaded vehicle (2)
Apply rust preventive to the bottom of the car body. Then, the automobile (2) after applying the rust preventive agent is placed on the vehicle conveyor table (10) and transferred from the end of the conveyor (4) to the second transfer conveyor (
conveyor (4) of the drying line (43) via the drying line (47)
Transfer it onto the starting end of 5).

The transfer mechanism by the second transfer conveyor (47) is exactly the same as that of the first transfer conveyor (46), so the explanation thereof will be omitted. Next, drying line (4
The vehicle transport platform (10) transferred onto the starting end of the transport conveyor (45) in step 3) is moved forward by the drive of the conveyor (45), and the loaded vehicle is moved forward while passing through the inside of the drying chamber (44). The part (2) where the rust preventive agent is applied is dried and reaches the last accumulation line (48). Note that the vehicle loading mechanism (20) disposed at the starting end of the first accumulation line (41) and the vehicle unloading mechanism (30) disposed at the terminal end of the last accumulation line (48) are similar to the first one. Since the structure is the same as that of the embodiment, the explanation thereof is omitted here.

In addition, in each of the above embodiments, the wheel receivers (
16) The shape and attachment means of (17) are not limited to those shown in the drawings, and may be of other currencies. Wheel holder (
16) In order to stably stop the vehicle (2) such as a car on the conveyor table (10), the (17) is provided with a recess or hole into which the lower end of the wheel is fitted, or has an appropriate height. It is preferable to provide a stopping convex portion having a stopper.

Additionally, a vehicle loading mechanism (20) and a vehicle unloading mechanism (
30) are arranged on both sides of the transport conveyor (4), but these may also be arranged on the - side of the transport conveyor (4). In that case, the wheel passing overhangs (23) (24) (33) (
34) is the sliding body (21) (3) on the − side of the conveyor (4).
1) Extending from the wheel receivers (16017) on both the left and right sides of the vehicle transfer platform (10) and between the wheel receivers (16) and the front wheel receivers (16)
and the front frame member (14) or the rear wheel receiver (17).
) and the rear frame member (15).

Further, in each of the above embodiments, the vehicle transport platform (10) of the present invention
Although the case where the rust preventive agent is applied to the bottom surface of the car body of the car (2) using the vehicle transport device has been described, the present invention is not limited to this, and the present invention can be similarly applied to cases where other processing or treatment is performed on vehicles such as cars.
