Claims (11)

Several coating lines (CL1)-(CL3) and a preliminary drying furnace (PB1)-(PB3) for preliminary drying of the coating zone for coating the paint on the object (W) and the coating applied in the coating zone, respectively; The above-mentioned several after the completion of the above-mentioned predrying furnace PB1- (PB3) is equipped with one main drying furnace MB set for common use with respect to said several coating lines CL1-CL3. The object W in the painting lines CL1 to CL3 is supplied to the above-mentioned main drying furnace MB, and the main drying is performed in the main drying furnace MB. The drying condition in the main drying furnace MB is set as a predetermined common drying condition, and the drying conditions of several preliminary drying furnaces PB1 to PB3 are performed in a corresponding coating line. The painting method is characterized in that the paper is set independently according to the painting conditions. The main drying furnace (MB) according to claim 1, wherein the object (W) is sequentially passed through at least two coating lines without passing through the drying furnace (MB) in the middle, and after the preliminary drying is finished in the final coating line, Coating method characterized in that the main drying in the). The rotating machine according to claim 1, wherein the rotating cart D2, which is independent of the drying line MBL leading to the main drying furnace MB, has a function of rotating the object W around a horizontal axis. It has a painting line and a non-rotating painting line on which the general truck D, which does not have the function of rotating the object W, travels, and gives the object W between the drying line MBL and the rotating painting line. A receiving method is performed, and the coating method is characterized in that the object (W) is exchanged between the drying line (MBL) and the non-rotating coating line. The preliminary drying furnace (PB1)-(according to claim 1, wherein the coating line of a part of the several painting lines (CL1)-(CL3) is provided between the coating area and the preliminary drying furnace (PB1)-(PB3). A coating method, characterized in that preheating is performed at a temperature lower than the ambient temperature of PB3). Coating area for applying paint to each object (W) and several painting lines with pre-drying furnaces (PB1)-(PB3) for pre-drying the coating applied in the coating area and one main drying furnace (MB) ), The drying line MBL set to pass through this drying furnace MB, and the object W flowing independently of each coating line separately from the preliminary drying furnaces PB1-PB3, respectively. A downstream painting device, characterized in that it is provided with isotropic means for transferring from each painting line to the drying line (MBL). The transfer device according to claim 6, wherein the drying line MBL is configured independently of the plurality of coating lines, and the transfer means transfers the object W from each coating line to the drying line MBL. The coating apparatus comprised by J1)-(J2). 7. The coating according to claim 6, wherein the coating lines of a part of the several coating lines are connected so that the object W flows in sequence through the coating line of the part without passing through the main drying furnace NB. The coating device, characterized in that the object (W) after passing through the pre-drying furnace (MB) of the coating line through which the object (W) flows only last in the line is transferred to the drying line (MBL) by a conveying means. The object transfer truck according to claim 6, wherein a part of the coating line of the coating line is configured independently of the other coating line and the drying line MBL, and the object transfer truck that runs the portion of the coating line is the object W. And a rotary bogie (D2) having a function of rotating the periphery of the horizontal axis. The temperature of the preliminary drying furnaces (PB1)-(PB3) in the above-described part of the coating line, if left unchanged, is above the temperature at which paint flows down due to the influence of gravity. The coating device characterized in that the object (W) is rotated around the horizontal axis to prevent the paint flowing down during the pre-drying in the pre-drying furnace (PB1)-(PB3) in a part of the painting line. . The method according to claim 6, wherein the coating line of a part of the above-described coating line is between the coating zone and the preliminary drying furnaces PB1-(PB3), which is lower than the ambient temperature of the predrying furnaces PB1-(PB3). A painting apparatus, characterized in that a preheating zone for preheating at a temperature is configured. ※ Note: The disclosure is based on the initial application.
