DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for preventing paint from being scattered on a plurality of conveyor trucks, each of which carries an object to be coated and passes through the inside of a coating booth in cascade.

[0002]

2. Description of the Related Art On a floor of a painting booth for applying a paint to an automobile body, a conveyor is provided on a conveyor truck on which an automobile body is mounted to pull and run with a chain.
The automobile body painted by the spray gun inside the painting booth is conveyed to the drying oven in the next process while being mounted on the conveyor truck. A conveyor truck equipped with an automobile body is stored between the painting booth and the drying furnace for a predetermined time, where the conveyor truck is separated from the chain and temporarily stops running.

[0003]

Conveyor trucks disconnected from the chain for storage may run slightly by inertia without stopping immediately and come into contact with the rear of the already stopped conveyor truck. In order to prevent damage due to direct contact between the conveyor trucks, a stopper is provided to abut on the conveyor truck adjacent to the front end or the rear end of the conveyor truck.

By the way, since paint particles adhere to the conveyor truck passing through the interior of the painting booth, the paint adhered to the stopper comes into contact with the conveyor truck, and the paint adheres peels off and scatters. There is a problem that it adheres to the undried coating film of the body and deteriorates the coating quality.

The present invention has been made in view of the above circumstances, and has as its object to prevent paint from scattering due to contact between conveyor trucks.

[0006]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a paint for a conveyor truck provided on a plurality of conveyor trucks, each of which carries an object to be coated and passes through the inside of a coating booth in cascade. An anti-scattering device, in which a stopper is provided at one end in the traveling direction of the conveyor truck, the stopper being capable of contacting the conveyor truck adjacent to the one end side in the traveling direction,
A paint scattering prevention cover is provided at the other end of the conveyor trolley in the traveling direction to cover a contact portion with a stopper provided on the conveyor trolley adjacent to the other end in the traveling direction.

Embodiments of the present invention will be described below with reference to the drawings.

1 to 3 show an embodiment of the present invention. FIG. 1 is a side view of a storage section of a conveyor truck, and FIG.
1 is a view in the direction of the arrow 2 in FIG. 1, and FIG. 3 is an enlarged view of a part 3 in FIG.

As shown in FIGS. 1 and 2, a conveyor truck 1 for transporting an automobile body B to be coated from a coating booth to a drying oven has a plurality of wheels 3 rolling on a pair of left and right rails 2 and 2. And a bogie main body 4 having. An endless conveyor chain 5 circulates between the rails 2, 2, and a locking claw 6 is provided on the upper surface of the conveyor chain 5 at predetermined intervals so as to be able to move up and down. On the lower surface of the front part of the bogie main body 4, a dog 7 with which the locking claw 6 can be engaged is projected downward.
Accordingly, the conveyor truck 1 is pulled by the conveyor chain 5 and travels with the dog 7 engaged with the locking claw 6, and the dog 7
Chain 5 in a state where the engagement between the
Is separated from the storage.

As is apparent from FIG.
A pair of left and right stoppers 8, 8 that can abut on the rear edge of the bogie body 4 of the conveyor bogie 1 on the front side are protrudingly provided at the front end of the bogie main body 4 of each conveyor bogie 1. A pair of left and right paint scattering prevention covers 9, 9 protruding toward the front edge of the bogie main body 4 of the conveyor bogie 1 on the rear side are provided at the rear edge of the bogie main body 4.

Each paint scattering prevention cover 9, 9 is disposed so as to cover the upper part of the corresponding stopper 8, 8.
The longitudinal length L ₁ of the stoppers 8, 8 is formed slightly larger than the longitudinal length L ₂ of the paint scattering prevention covers 9, 9 (see FIG. 3). width W ₁ is slightly smaller than the lateral width W ₂ of the paint scattering prevention cover 9, 9 (see FIG. 2).

When the conveyor truck 1 to which the paint particles have adhered after passing through the interior of the coating booth reaches the storage section shown in FIG. , 8 abut against the trailing edge of the truck body 4 of the front conveyor truck 1. At this time, even if the paint adhered to the stoppers 8, 8 or the bogie main body 4 is peeled off by the impact, the paint is prevented from being scattered by the paint scatter prevention covers 9, 9 covering the upper portions of the stoppers 8, 8. Is done. As a result, the peeled paint is prevented from adhering to the automobile body B on the conveyor trolley 1, and the deterioration of the paint quality is prevented.

Although the embodiments of the present invention have been described in detail, the present invention is not limited to the above embodiments, and various design changes can be made.

For example, if the paint scattering prevention covers 9 and 9 cover not only above the stoppers 8 but also both left and right sides, the scattering of the paint can be more reliably prevented. Further, in the embodiment, the stoppers 8 and 8 are provided on the front edge of the bogie main body 4 and the paint scattering prevention covers 9 and 9 are provided on the rear edge. However, the positional relationship can be interchanged. Further, the number of the stoppers 7, 7 and the paint scattering prevention covers 9, 8 can be changed.

[0015]

As described above, according to the present invention, there is provided a stopper which can be brought into contact with a conveyor truck adjacent to one end in the traveling direction of a conveyor truck which carries an object to be coated and traverses the inside of a coating booth in cascade. With the provision of the paint scattering prevention cover, which covers the contact portion with the stopper provided on the conveyor truck adjacent to the other end in the traveling direction, the paint separated from the contact portion by the paint scattering prevention cover is scattered. Can be prevented from being attached to the object to be coated.
