[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a conveyor for carrying a conveyor truck on which an object is placed along the floor of a painting booth provided with an automatic painting device such as a top machine for raising and lowering a painting machine. About rails.

[0002]

2. Description of the Related Art For example, in a painting booth for painting an automobile body, generally, as shown in FIG. 2, conditioned air supplied from an air supply chamber 9 formed in a ceiling portion flows down into a painting chamber 10, The paint mist that has not adhered to the article to be coated W is sucked into the venturi device 11 disposed under the floor, brought into gas-liquid contact, and collected. An automatic coating device such as a top machine 12 for raising and lowering the coating machine 4 is installed in the coating room 10. Conveyor rails are laid.

[0003] The top machine 12 lowers the coating machine 4 to near the floor surface 13 when changing the color of the coating material, and removes the coating material remaining inside the coating machine 24 and the coating pipes with cleaning air or cleaning liquid. The air is blown away toward the venturi device 11. The floor 13 of the painting booth
The gutter-shaped rail 1 laid thereon is formed of a C-shaped channel material for accommodating and guiding the wheels R of the conveyor truck C, and electrically supplies water between the channel R and the wheels R of the conveyor truck C with water supplied therein. , And the article placed on the conveyor truck C is reliably grounded.

[0004]

However, the coating machine 4 of the top machine 12 is lowered and the venturi apparatus 1 is lowered.
When the paint and the cleaning liquid are thrown away and blown toward 1, the sprayed paint and the like float on the water supplied in the rail 1 to form a film of the paint component on the surface of the water, and the film arrives next on the conveyor truck. It adheres to the wheel R of C. Then, since the conveyor cart C carries the article to be coated W into the baking drying oven, the paint component adhered to the wheels R in the drying oven may be dried and solidified, which may hinder the rotation of the wheels R.

[0005] For this reason, the conveyor trolley C, from which the object W has been unloaded after drying has been completed, is periodically inspected, and if paint is attached to the wheels R, the paint is knocked down. Once dried and cured, the paint cannot be easily removed.

[0006] Therefore, the present invention is intended to provide a paint film on the rail located in the zone where the paint is sprayed under the floor of the painting booth with air supply by dropping the paint machine of the top machine. It is a technical problem to prevent the formation of the paint and prevent the paint from adhering to the wheels even when the bogie passes.

[0007]

SUMMARY OF THE INVENTION In order to solve this problem, the present invention relates to a method of coating a coating along a floor of a painting booth provided with an automatic coating device such as a top machine for raising and lowering a coating machine. In the conveyor rail of the painting booth with air supply that runs a conveyor truck carrying objects, the entire rail is
It is formed of a gutter-shaped rail that stores water supply in a groove for accommodating and guiding the wheels of the conveyor trolley. On the groove wall of the groove of the gutter rail,
A notch is formed to overflow the water supply in the groove, and a water supply nozzle is provided that injects water toward the inside of the groove from both front and rear sides of the gutter type rail with the notch interposed therebetween. I do.

[0008]

According to the present invention, when the paint machine of the top machine is lowered and the paint or the like is discarded and blown below the floor of the painting booth with air supply, the paint mist is introduced into the groove of the gutter-shaped rail located in the discarding zone. However, the notch that overflows the water supply in the groove is formed on the groove wall of the groove of the gutter-shaped rail, so that the paint mist together with the overflowed water flows under the floor of the paint zose. Is dropped into the paint recovery Venturi device formed in the above. Therefore, by the time the next truck arrives, the paint mist in the groove of the gutter rail is discharged, and the paint mist does not adhere to the wheels of the truck.

Further, since a water supply nozzle is provided for spraying water from both front and rear sides of the trough-shaped rail toward the inside of the groove of the rail with the notch therebetween, the water in the groove is forcibly removed. The paint mist is reliably discharged from the notch even if the rail is slightly inclined.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be specifically described below based on embodiments shown in the drawings. FIG. 1 is a perspective view showing a conveyor rail of a painting booth with air supply according to the present invention. FIG. 2 is a front view showing a painting booth on which the conveyor rails are arranged.

In FIG. 1, reference numeral 1 denotes a gutter-type rail for storing water supplied from a water supply device (not shown) in a concave groove 2 for accommodating and guiding wheels of a conveyor truck. A mountain-shaped rail 3 on which a wheel R of a conveyor truck C is mounted is formed in the bottom of the concave groove 2, and the mountain-shaped rail 3 and the wheel R running on the mountain-shaped rail 3 are electrically connected via water. The article to be coated W is connected to the ground.

The gutter-type rail 1 located in the zone where the coating machine 4 of the top machine 12 shown in FIG.
A notch 6 is formed in a groove wall 5 of the concave groove 2 to allow water in the concave groove 2 to overflow. This notch 6
For example, the inner groove wall 5 is cut out from the upper end side to a certain depth to store water at a certain depth in the concave groove 2, and when the water is further supplied, the water is overflown. Has been established.

Further, in the concave groove 2, between the wheel R running on the mountain-shaped rail 3 and the groove wall 5, the rail 1 is inserted from both front and rear sides of the gutter-shaped rail 1 with the notch 6 interposed therebetween. Water supply nozzles 7, 7 for jetting water toward the inside of the concave groove 2 are provided. In the case of the embodiment, each water supply nozzle 7 is disposed outside the zone where the paint or the like is discarded and blown, and each nozzle 7 is formed with an outlet 7a that blows water toward the zone. The water supply in the groove 2 of the gutter-shaped rail 1 located in that zone is caused to overflow vigorously when the air is blown away. Reference numeral 8 denotes a water supply pipe for supplying water to each nozzle 7 at a predetermined pressure.

The above is an example of the configuration of the present invention, and its operation will be described below. When the coating of the previous workpiece W is completed by the coating machine 4 of the top machine 12, the remaining paint in the coating machine 3 travels to the venturi apparatus under the floor before the next workpiece W is conveyed. A part of the paint that has been thrown away and blown away is sprayed on the gutter-shaped rail 1 provided on the floor.

At this time, since the water supply in the concave groove 2 of the gutter-shaped rail 1 overflows through the notch 6, the paint floating on the water surface of the concave groove 2 is transferred to the venturi apparatus 11 together with the water. The paint is not washed away in the gutter rail 1. In addition, if water is jetted from each water supply nozzle 7 and water is vigorously overflowed from the inside of the groove 2 of the gutter-shaped rail 1 located in the zone where the paint is discarded and blown, through the notch 6, The paint can be reliably discharged, and this is particularly effective when the gutter-shaped rail 1 is disposed at an angle. Furthermore, if the water is sprayed from each water supply nozzle 7 when the conveyor truck C passes as well as when the paint is thrown away, the spray pressure and the jet flow can reduce the dirt attached to the wheels R of the conveyor truck C. It can be washed.

The length and the depth of the notch 6 can be set arbitrarily. If the amount of water supplied from the water supply nozzle 7 is large, the notch may be cut to the lower end. Further, it is desirable that the water supply nozzle 7 is disposed outside the zone where the paint is discarded and blown. However, the present invention is not limited thereto, and the water supply nozzle 7 is disposed inside the zone if the notch 6 is provided therebetween. It may be the case.

[0017]

As described above, according to the present invention, a notch is formed in the groove wall of the groove of the gutter-shaped rail located in the zone where the air is blown out, and the gutter-shaped rail is sandwiched by the notch. Water is sprayed into the groove by the water supply nozzles provided on the front and rear sides of the groove, and the water in the groove is forced to overflow from the notch, so even if the rail is slightly inclined,
Paint mist that has been thrown away from the painting machine and dropped into the groove of the gutter-shaped rail can be reliably discharged from the notch together with the water in the rail, and the paint adheres to the wheels of the conveyor truck traveling on the rail. It has a very good effect of not having to do it.
