本発明は、自動車等の被塗物の塗装ライン前処
理工程における改良された水洗方法に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an improved method for rinsing objects to be coated, such as automobiles, in a pretreatment process of a painting line.
自動車の車体等の各種工業製品は、その表面に

される。 Conventionally, pretreatment in the painting process has usually been carried out as follows. In a pre-degreasing step, the object to be coated, which is suspended by a conveyor such as an overhead conveyor, is preliminarily degreased by spraying an alkaline degreaser from a tank with a degreaser spraying device. In this preliminary degreasing step, press processing oil, dust, etc. adhering to the surface of the object to be coated are mainly removed by the degreasing power and spray pressure of the alkaline degreaser.

等を施し、ついで電着塗装等の塗装が施される。 Next, in the degreasing process, sodium phosphate, sodium carbonate, sodium silicate,
Degreasing treatment is carried out by immersing it in a degreasing agent whose main ingredients are an alkali such as sodium hydroxide, a surfactant, and a surface conditioner blended as necessary. The coated object that has been degreased in this way is subjected to spray washing, immersion washing, etc. in the water washing process, and then immersed in a chemical conversion treatment tank containing a metal phosphate such as zinc phosphate or other chemical conversion treatment liquid. Then, a chemical conversion treatment is performed, and further, spray washing, immersion washing, etc. are performed in the water washing process, and then painting such as electrodeposition coating is applied.
しかしながら、このような前処理工程にあつて

浸漬により水洗を行なう必要があつた。 However, in such a pre-treatment process, the degreaser is alkaline, whereas the chemical conversion treatment liquid used in the subsequent process is acidic, so after repeated spraying and washing several times, the degreaser is alkaline. It was necessary to wash with water after soaking. Furthermore, when the chemical conversion treatment liquid is brought into the electrodeposition bath, the pH of the electrodeposition bath fluctuates, so it was necessary to repeat spray washing several times and then perform water washing by complete immersion.
しかして、前記のごき脱脂処理や化成処理を噴

処理液等の汚染液やその希釈水洗水の除去を行な
つていた。 However, when the above-mentioned degreasing treatment or chemical conversion treatment is carried out by spraying or by immersion in each treatment tank, the paint adheres not only to the object to be coated but also to the hanger supporting the object. Although such processing liquid is washed away in the next step, the processing liquid and diluted washing water still remain in the hanger, and this drips and contaminates the surface of the object to be coated.
For this reason, an air blowing device has been installed to remove contaminated liquids such as degreasing liquids and chemical conversion liquids and their diluted washing water.

になるという問題点があつた。 However, in such conventional contamination prevention methods, the contaminated liquid and diluted washing water removed from the hanger by air blowing fall onto the surface of the workpiece, so Zn in the dripped contaminated liquid is + ,
The surface of the object to be coated is partially contaminated by droplets of miscellaneous ions such as Fe ++ and PO 4 -- . For this reason, in a post-process, for example, when electrodeposition coating is performed, there is a problem that differences in conductivity occur locally on the object to be coated, resulting in non-uniform coating thickness.

As shown in the figure, only the object to be coated is completely submerged during washing in the immersion washing tanks 9 and 14, and the upper part of the hanger 2,
For example, the arm part 16 is placed above the liquid level 17 and is blown with air by an air blowing device 18 provided at a position where air can be blown, and the contaminated liquid adhering to the vicinity of the upper part of the hanger is blown with air and dropped into the washing water. Remove. That is,
In the air blow device 18, an air supply riser 19 is attached to a frame (not shown) at the above-mentioned position of the washing water tanks 9, 14, and an air blow nozzle 20 is connected to the tip of the riser 19. The opening is at the upper part, for example, near the arm part 16. When the hanger is transported to a position where only the object 3 to be coated is completely immersed in the water and the hanger 2 is above the water surface, air is supplied (not shown) by the action of the detection means 21 such as a limit switch. When the device operates, air is supplied from the air supply riser 19 and blown from the air blow nozzle 20. As a result, contaminated liquids such as chemical conversion treatment liquid and degreasing treatment liquid adhering to the upper part of the hanger fall into the washing water in the water tank and are removed. Next, on the stairs where the object to be coated ascends from the water, a detection means such as a limit switch (not shown) is activated to stop the air supply device and stop the air blow. Next, the object to be coated which has been washed with water in this way is transported to a coating process and subjected to, for example, electrodeposition coating.

まつたくなくなる。 As explained above, according to the present invention, in the pretreatment process of a coating line in which pretreatment and coating are carried out while the object to be coated is supported and conveyed by a hanger, Blow the top of the hanger with air so that only the object to be coated is completely submerged and the top of the hanger is above the liquid level,
The water washing method used in the pre-treatment process of the painting line is characterized by removing the contaminated liquid adhering to the upper part of the hanger. Since it does not fall on the surface but falls on the surface of the washing water and is diffused and diluted in the washing water, there is no contamination of the surface of the object to be coated by droplets. Therefore, even if electrodeposition is performed, for example, local conductivity differences due to miscellaneous ions will not occur, and a uniform electrodeposition liquid film can be obtained. Further, since the contaminated liquid falls into the washing water tank by air blowing, the washing step for washing the contaminated liquid dripping by air blowing, which was conventionally necessary, can be omitted. Furthermore, since there is no influence from dripping of contaminated liquid, a large amount of air blowing can be performed at the same time, and quality defects are unlikely to occur.
