  First, the spindle coating apparatus 101 shown in FIGS. 2 and 3 is prepared. The spindle coating apparatus 101 includes an upper surface portion 103a having a rectangular shape in plan view, a lower surface portion 103b having a rectangular shape in plan view, and three rod-shaped connecting portions that connect three opposite corners of the upper surface portion 103a and the lower surface portion 103b. A frame 103 having 103c is provided. The upper end of a rod-shaped first shaft member 105 extending in the vertical direction is fixed to the central portion of the upper surface portion 103a of the frame 103. The lower end of the first shaft member 105 is a first shaft that rotates the first shaft member 105 clockwise at a constant speed of 60 RPM (direction indicated by arrow X1 in FIG. 3) when viewed from above. The rotating device 107 is connected. The first rotating device 107 is placed on the lower surface portion 103 b of the housing 103. In the vicinity of the lower end portion of the first shaft member 105, a turntable 109 as a disk-like rotating member is fixed so that the first shaft member 105 penetrates the center of the turntable 109 vertically. A rotating plate 111 as a circular rotating member is fixed near the upper end of the first shaft member 105 with the first shaft member 105 penetrating vertically through the center of the rotating plate 111. Accordingly, when the first rotating device 107 rotates the first shaft member 105 clockwise when viewed from above, the rotating base 109 and the rotating plate 111 are viewed from above around the first rotating shaft A extending in the vertical direction. It can be rotated clockwise. Therefore, the first shaft member 105 and the first rotating device 107 constitute first rotating means. Four shaft members 113 serving as four holding means are attached in the vicinity of the periphery of the turntable 109 and the turntable 111. Each of the second shaft members 113 has a shaft portion 113a extending in the vertical direction, and the lower end portions of the shaft portions 113a are spaced from each other on the circumference of the same circle C centered on the first rotation axis A on the turntable 109. The upper end portion of the shaft portion 113a is rotatably attached to the rotation plate 111 on the circumference of the same circle C centered on the first rotation axis A with an equal interval therebetween. . Therefore, the second shaft member 113 is rotatable around the second rotation axis B extending in parallel with the first rotation axis A on the circumference of the same circle C centering on the first rotation axis A. A plate-like first base end portion 113b protrudes radially outward with the plate surface in the circumferential direction of the second rotating shaft B slightly inside the longitudinal ends of each shaft portion 113a. . At the tip of the first base end 113b, a plate-like first tip 113c perpendicular to the first base end 113c extends in the counterclockwise direction around the second rotation axis B as viewed from above. Has been. A first mounting hole (not shown) is formed in each first tip portion 113c. Further, at a position that is shifted from the first base end portions 113b of each shaft portion 113a in the longitudinal direction by 90 ° clockwise relative to the first base end portion 113b as viewed from above around the second rotation axis B. The plate-like second base end portion 113d is provided so as to protrude radially outward with its plate surface facing the circumferential direction of the second rotation axis B. A plate-like second distal end portion 113e perpendicular to the second proximal end portion 113d extends from the distal end of the second proximal end portion 113d toward the counterclockwise direction of the second rotation axis B as viewed from above. ing. A second attachment hole (not shown) is formed in the second tip portion 113e. The protruding directions of the first base end portions 113b of the four holding members 113 are about the first rotation axis A of the second shaft member 113 when the turntable 109 and the rotation plate 111 are rotated clockwise as viewed from above. They are set so as to form an equal angle (0 ° in the state of FIG. 3) with respect to the traveling direction (the direction indicated by the arrow X in FIG. 3). Hereinafter, the traveling direction around the first rotational axis A of the second shaft member 113 by clockwise rotation when viewed from above the rotating table 109 and the rotating plate 111 is defined as a traveling direction X. The protruding directions of the second base end portions 113d of the four holding members 113 are also set to have an equal angle with respect to the traveling direction X (in the state of FIG. 3, an angle indicated by α in FIG. 3). Further, the lower end of the shaft portion 113a of the second shaft member 113 is a second rotating device as second rotating means for rotating the second shaft member 113 counterclockwise as viewed from above around the second rotating shaft B. 115. The second rotating device 115 is fixed to the turntable 109. The second rotating device 115 is connected with an input device 117 as setting means. A plurality of sets of setting positions around the second rotation axis B of the second shaft member 113 and a set time for holding the second shaft member 113 at the setting position are input to the input device 117. The input device 117 sets the input setting position and setting time, and the second rotation device 115 sets the position around the second rotation axis B of each second shaft member 113 set by the input device 117. The second shaft member 113 is rotated so as to be in the position, and each second shaft member 113 is rotated to the set position, and the second shaft member 113 of the second shaft member 113 is set for the set time corresponding to the set position. The operation of stopping the rotation around the rotation axis B is executed for each set of the setting position and the setting time set by the input device 117.

  In addition, a spray gun 119 for injecting paint P (see FIG. 4) is held by the second shaft member 113 in the vicinity of the corner of the outer periphery of the frame 103 where the connecting portion 103c is not formed. The spoiler 1 is disposed so as to approach the spray gun 119 in the injection direction by the rotation of the rotary table 109 and the rotary plate 111. The spray gun 119 is supported by the robot arm 121. By driving the robot arm 121, the spray gun 119 can slide up and down and left and right (up and down in FIG. 2 and up and down in FIG. 3).

  Next, screws 123 are inserted into the first insertion holes (not shown) of the first attachment portions 4 of the side spoilers 1 and the first attachment holes (not shown) of the second shaft members 113 of the spindle coating apparatus 101. By inserting, the 1st attaching part 4 of each side spoiler 1 is fastened to the 1st front-end | tip part 113c of each 2nd shaft member 113. As shown in FIG. Further, a screw 123 is inserted through a second insertion hole (not shown) of the second attachment portion 6 of each side spoiler 1 and a second attachment hole (not shown) of each second shaft member 113 of the spindle coating apparatus 101. By doing so, the second attachment portion 6 of each side spoiler 1 is fastened to the second tip portion 113e of each second shaft member 113. Thereby, each side spoiler 1 is held by the second shaft member 113. In this state, the protruding directions of the first base end portions 113b of the four holding members 113 form an equal angle with respect to the traveling direction X, and the protruding directions of the second base end portions 113d of the four holding members 113 are the same. The four side spoilers 1 are in a state in which a common portion is directed in the traveling direction X because the angles are set to be equal to each other with respect to the traveling direction X. For example, in the state of FIG. 3, the four side spoilers 1 point the first painted surface 1 a in the traveling direction X.

  Moreover, while inputting the position around the 2nd rotating shaft B of the 2nd shaft member 113 when the 1st coating surface 1a of the side spoiler 1 faces to the advancing direction X to the input device 117 as a 1st setting position, The time for retaining the second shaft member 113 at the first set position is input as the first set time. Furthermore, while inputting the position around the second rotation axis B of the second shaft member 113 when the second coating surface 1b of the side spoiler 1 is directed in the traveling direction X to the input device 117 as a second set position, The time for holding the second shaft member 113 at the second set position is input as the second set time. At this time, a time longer than the second set time is input as the first set time. In addition, the position of the second shaft member 113 around the second rotation axis B when the connecting wall portion 1c of the side spoiler 1 greatly protrudes to the outer peripheral side of the turntable 109 and the rotation plate 111 is set to the input device 117 as a third setting. While inputting as a position, the time which keeps the 2nd shaft member 113 in the said 3rd setting position is input as 3rd setting time. Then, the input device 117 sets the input first to third setting positions.

  Thereafter, the first rotating device 107 and the second rotating device 115 are activated, and the spray gun 119 is started to inject the paint P. Then, the first rotating device 107 rotates the first shaft member 105, the rotating table 109, and the rotating plate 111 clockwise at a constant speed of 60 RPM as viewed from above, and the second rotating device 115 includes four A first rotation process for rotating the second shaft member 113 to the first set position is executed. Thereby, as shown in FIGS. 4-6, the 1st coating surface 1a of the side spoiler 1 turns to the advancing direction X. As shown in FIG. 4 to 6, the side spoiler 1 indicated by a solid line approaches the spray gun 119 in the injection direction by the rotation of the rotary table 109 and the rotary plate 111. In this state, the second rotating device 115 stops the rotation of the four second shaft members 113 for the first set time. As a result, while the four second shaft members 113 are rotated to the first set position, the rotary base 109 and the rotary plate 111 are rotated at a constant speed as viewed from above, and the spray gun 119 is applied to the paint. The first painting process for injecting P is executed for a first set time. During the first painting process, the spray of the paint P is performed while moving the spray gun 119 in the vertical direction. Thereby, the coating material P is apply | coated to the 1st coating surface 1a of the four side spoilers 1 over the whole.

  When the first set time elapses after the second shaft member 113 is rotated to the first set position, the second rotating device 115 rotates the four second shaft members 113 counterclockwise as shown in FIG. A second rotation process is performed in which the rotation is performed in the direction indicated by the arrow Y1 in FIG. 6 to the second set position. Thereby, as shown in FIGS. 7-9, the 2nd coating surface 1b of the side spoiler 1 faces the advancing direction X. As shown in FIG. 7 to 9, the side spoiler 1 indicated by a solid line approaches the spray gun 119 in the injection direction by the rotation of the rotary table 109 and the rotary plate 111. In this state, the second rotating device 115 stops the rotation of the four second shaft members 113 for the second set time. As a result, while the four second shaft members 113 are rotated to the second set position, the rotating base 109 and the rotating plate 111 are rotated clockwise at a constant speed as viewed from above, and the spray gun 119 is applied to the paint. The second coating process for injecting P is executed for the second set time. During the second painting step, the paint P is sprayed while moving the spray gun 119 in the vertical direction. Thereby, the coating material P is apply | coated to the 2nd coating surface 1b of the four side spoilers 1 over the whole.

  When the second set time elapses after the second shaft member 113 is moved to the second set position, the second rotating device 115 moves the four second shaft members 113 counterclockwise to the third set position. A third rotation step for rotation is performed. As a result, as shown in FIG. 10, the connecting wall portion 7 of the side spoiler 1 greatly protrudes to the outer peripheral side of the rotary table 109 and the rotary plate 111. In this state, the second rotating device 115 stops the rotation of the second shaft member 113 for the third set time. As a result, while the four second shaft members 113 are rotated to the third set position, the rotary table 109 and the rotary plate 111 are rotated at a constant speed as viewed from above, and the spray gun 119 is applied to the paint. The third painting process for injecting P is executed for a third set time. During the third coating step, the spray of the coating P is performed on the path R1 (see FIG. 2) formed above the side spoiler 1 and the path R2 (FIG. 2) formed below the side spoiler 1. (See above) This is performed while sliding the spray gun 119 up and down. The path R1 is curved inward in the radial direction of the rotary table 109 and the rotary plate 111, and the path R2 is curved inward in the radial direction of the rotary base 109 and the rotary plate 111. Thereby, the coating material P is apply | coated to the 3rd coating surface 1c of the four side spoilers 1 over the whole.

  Thereafter, the coating operation of the side spoiler 1 is completed by drying the paint P.

  Thus, since the turntable 109 and the rotating plate 111 are rotated during the execution of the first to third rotating steps, between the first to third rotating steps and the first to third coating steps. It does not take time to start the turntable 109 and the turntable 111. Therefore, the time required for the painting work is shortened.

  Therefore, according to the first embodiment, since the paint P is applied to the painted surfaces 1a to 1c of the side spoiler 1 for a time corresponding to the set time, the desired paint P is set as the set time of the painted surfaces 1a to 1c. By inputting the time according to the thickness of the input device 117 to the input device 117, it is possible to apply the coating P having a desired thickness to each of the coating surfaces 1a to 1c, and reduce the waste of the coating P.

  Also, the paint P is sprayed by the spray gun 119 in a state where the first paint surface 1a and the second paint surface 1b approach the spray gun 119 in the spraying direction of the paint P by the rotation of the turntable 109 and the rotating plate 111. Therefore, the coating efficiency is good and the waste of the paint P can be reduced.

  Moreover, since the amount of the coating material P applied to the first coating surface 1a wider than the second coating surface 1b is larger, the first and second coating surfaces 1a and 1b have a uniform thickness. Can be painted.

  In the above embodiment, the first shaft member 105 is rotated clockwise. However, the first shaft member 105 may be rotated counterclockwise.

  In the above embodiment, the second shaft member 113 is rotated counterclockwise. However, the second shaft member 113 may be rotated clockwise, or may be rotated not only in one direction but also in both directions.

  In the above embodiment, the rotation of the second shaft member 113 is stopped for a set time while the rotation of the rotating table 109 and the rotating plate 111 is rotated and the spray gun 119 is sprayed with the coating material P. The total time for which the second shaft member 113 is positioned at the set position may be set as the set time without stopping the rotation of the member 113. That is, in the said embodiment, although the coating process for set time was collectively performed once, it may be divided and performed so that the execution time of the multiple times of coating process may be set time. Good.

  Further, the setting position set in the input device 117 may have a width. That is, as a setting position, a range from a predetermined first position to a second position can be set, and a time period during which the second shaft member 113 is located in the range from the first position to the second position. The total may be set time. In this case, when the second shaft member 113 is between the first position and the second position, the second shaft so that the rotation speed of the second shaft member 113 is lower than when the second shaft member 113 is in another position. The rotation speed of the member 113 may be controlled.

  Moreover, in the said embodiment, although the two coating surfaces 1a and 1b were provided as a coating surface coated in the state which faced the advancing direction X, you may provide three or more coating surfaces. In addition, when three or more painted surfaces having different widths are provided as the painted surface to be painted in the traveling direction X, the longer the painted surface, the longer the painted surface is set. Also good.

  In the above embodiment, four second shaft members 113 are provided. However, the number of second shaft members 113 may be other than four as long as it is plural.

  Moreover, in the said embodiment, although this invention was applied to the painting of the side spoiler 1, it is applicable also to the coating of other vehicle exterior components and vehicle interior components.

  INDUSTRIAL APPLICABILITY The present invention is useful as a spindle coating method and a spindle coating apparatus used for painting a workpiece such as a vehicle exterior part.
