CONSTITUTION: A waiting line CRS antenna(80) induces the information regarding a body to be managed before shipping out by reading the inherent number of a vehicle body completed with a middle coat painting process. The body information is then delivered to a central control room and a vehicle waiting conveyor belt is controlled by a vehicle waiting conveyor belt PLC(Programmable Logic Controller)(20) for the entry of the vehicle body into the vehicle waiting line. The central control room(10) herein controls to arrange the vehicle body in the same color when the vehicle body enters a primary line(31) and a secondary line(32) of the vehicle waiting line by outputting a control signal to the vehicle waiting conveyor belt PLC after grasping a color by analyzing the inherent number of the vehicle body. Thereafter, the body is classified into a primary top coat painting line(50) and a secondary top coat painting line(60) by colors to be input by a top coat painting CRS antenna(40). With the application of an equal color continuous input manner, not first-input-first-output manner during the motion of the vehicle, the consumption of waste paint and waste thinner is reduced.

Description

Painting Line Transport Unit for Vehicles

The present invention relates to a vehicle transport apparatus of a top coat line, and in particular, by applying the same color continuous input method instead of a first-in first-out method when moving a vehicle to a water escape evacuation line, the waste generated when cleaning the color according to the color replacement of the top coat body It relates to a vehicle transport apparatus of the top coat line, characterized in that to reduce the consumption of paint and waste thinner.

In general, the vehicle body assembled in the assembly line of the automobile factory is painted in the painting line through the process as shown in FIG.

At this time, when painting in the painting line, after the pretreatment process and electrodeposition process, the car body is tacked off for the touch drying of the base paint by electrodeposition, and the film is sprayed on the outside of the car body that is turned off. After forming the intermediate outer coating, and after performing the intermediate outer coating, the intermediate inner coating to form the film inside the vehicle body by spraying is performed.

In addition, after performing the intermediate inner coating, the intermediate outer coating and the intermediate inner coating may be formed by manually picking up the intermediate film so that the film is not formed, and performing the intermediate pick-up. In order to prevent the film from being peeled off, put it in an oven and apply heat to cure the painted part of the car body.

In addition, after hardening the part coated by the middle oven, it is ticked off for the dry touch of the base paint, and after the tick off, the outside of the vehicle body is electrostatically coated to improve the arrival efficiency.

At this time, the electrostatic coating is a solvent-added oil-soluble paint and the color of the paint required by the consumer is used.

In addition, after the vehicle body is electrostatically coated outside the top of the body, the interior of the body is electrostatically coated, and after the exterior and inside of the body are electrostatically coated, the outside of the body is air-conditioned to match the color of the midway and the top coat painted on the outside of the body. To paint.

At this time, since the inside of the vehicle body does not look inward from the outside, the color does not have to match, and the inside of the vehicle body does not perform air coating.

In addition, after air painting the exterior of the vehicle body, the inside of the vehicle body is cree-coated to protect the base paint, and after the inside of the vehicle body is cree-coated, the outside of the vehicle body is cree-coated.

In addition, after performing the top coat outer cree coating, the exterior is polished and at the same time, heat is applied in an oven to protect the vehicle body, thereby curing the painted portion.

On the other hand, in the above painting process, after the intermediate process is finished, the transfer to the water-based evacuation line to wash the water and then to the top coat, when the transfer to the top coat, to enter a line at a certain ratio by the color of the vehicle do.

As described above, the interior of the vehicle body is electrostatically coated after the exterior of the vehicle body is electrostatically coated, and after electrostatic coating of the exterior and the interior of the vehicle body, the color of the vehicle body is matched to the color of the intermediate and the top coat. This is because the outside should be air-painted.

Therefore, the higher the ratio of the same color according to the color of the vehicle when entering the finished vehicle into the top coat line, the next process is advantageous, reducing the consumption of waste paint and waste thinner generated during cleaning due to color replacement. You can do it.

However, since the apparatus up to now is designed to enter the vehicle by the first-in first-out method in the water escape evacuation line, as shown in FIG. 2, the first line of the top coat by the top color Reschedule Storage (CRS) antenna. There is a problem that the color exchange rate is lowered by adjusting the color ratio of the vehicle only in the vehicle entering the second line of the overconversion.

That is, the central control room 10 applies a control signal to the water-repellent conveyor belt PLC 20 to induce the vehicle to enter the first line 31 and the second line 32 of the water-repellent evacuation line 30. According to the concept, one vehicle is transferred to the first line 31, and then the vehicle is transferred to the second line 32, and then the vehicle is transferred to the first line 31.

Then, when the body number of the vehicle is output to the central control room through the top-level CRS antenna 40, the central control room 10 distinguishes the color of the vehicle and the first and second lines 50 and 60 to the top line. It will enter the vehicle separately.

As a result, conventionally, the vehicle which has been subjected to the intermediate process by the water-based C / V 70 is transferred to the water-barrier evacuation line, and the PLC 20 of the water-based C / V 70 is divided into two lines by the first-in first-out method. Because of the separation, when separating the top entry vehicle by the top-level CRS antenna 40, it is not easy to separate by color.

Therefore, the consumption of waste paint and waste thinner increases upon cleaning due to color replacement of the body, which leads to a problem that leads to an increase in cost of the painting process.

The present invention is to solve the above problems,

By installing a water-based CRS antenna at the entrance point of the water escape evacuation line, the car enters the water evacuation evacuation line at a certain ratio according to the color of the vehicle. The purpose is to reduce the consumption of paint and waste thinner.

As a means for achieving the above object,

The present invention installs a water-repellent CRS antenna at the entrance point of the water-repellent evacuation line, and recognizes the body number through the water-repellent CRS antenna and enters the water-repellent evacuation line at the water-repellent evacuation line 1 and the water-repellent evacuation line 2 according to the body color. It is characteristic to provide.
