Conventionally, as an automatic coating method for multiple rows of steel sections being transported,
As shown in Fig. 1 or 2, one or two section steel edge detection sensors a installed for one row of section steel detect the right and/or left flange ends of the section steel. Two painting instruction sensors C that are detected and linked are installed above the shaped steel in each row, and both sensors a.

By installing multiple sets of combinations and arrangements of C according to the number of rows of section steel, when painting by reciprocating the painting guns d and e in the width direction of multiple rows of section steel, it is possible to At each position of the sensor C for painting instructions on the shaped steel, the painting method is such that the painting guns d and e start and finish painting one after another toward the center p of the outer flange surface and the upper end f of the flange of the shaped steel. I'm taking it.

しかしながら、塗装指示用センサーCからの電気信号に

(1) At the start of painting, there is a time lag until the air supply solenoid valve opens in response to an electrical signal from the painting instruction sensor C, and the painting gun is triggered by the air pressure supplied by the opening of the solenoid valve. There is a time lag between when the metal is drawn, the needle valve opens, and the paint is expelled from the nozzle tip.

(2) At the end of painting, the air pressure is released due to the time lag until the air supply solenoid valve closes in response to the electric signal from the painting instruction sensor C, and the air pressure is released due to the closing operation of the solenoid valve. The valve closes with spring action,
This causes a time lag until paint discharge stops.

Due to the above-mentioned time lag, if a deviation occurs between the painting instruction position by the painting instruction sensor C and the actual painting start/end position, overspray loss or unpainted parts will occur in the gaps between the rows of shaped steel.

この場合、そのタイムラグに合わせて形鋼の列間隔を広

In this case, if the spacing between the rows of shaped steel is widened to accommodate the time lag, the width of the coating equipment will need to be widened, which will be uneconomical.

As explained above, in the present invention, the projection direction in which paint is projected onto the plurality of rows of shaped steel transported by the transport table is viewed in the width direction of the shaped steel, and the direction in which paint is projected onto the shaped steel is mutually distributed as it goes forward. At least one pair of painting guns arranged opposite each other at an angle are moved back and forth in the width direction of the plurality of rows of shaped steel to project paint. By setting the row spacing of the plurality of rows of section steel so that the center of the outer flange surface of the section steel of the next row is located on the extension of the line connecting the upper edge of the outside flange surface of the section steel of In the row spacing of multiple rows of steel sections, there is no overspray loss or coating leftover due to the conventional time lag, and the coating instruction sensor set at a predetermined position corresponding to the multiple rows of steel sections eliminates the One of the pair of painting guns projects the center of the outer flange surface of the section steel, and the other one projects the upper end of the flange of the section steel, giving instructions to start and end painting at both extreme positions. There is no overspray loss or unpainted area at the outside positions of the rows of shaped steel, and the effect is that paint loss can be reduced and the coating film thickness can be made uniform.

Furthermore, in the case of multiple rows of steel sections, it is only necessary to space the rows apart by a certain distance, so when painting sections of the same size, the present invention [
According to this method, there is an advantage that the width of the coating equipment can be smaller than that of the conventional method.

1. The direction in which paint is projected onto the multiple rows of steel sections transported by the transport table is determined by looking in the width direction of the steel sections.
When projecting paint by reciprocating in the width direction of the plurality of rows of shaped steel, at least one pair of painting guns arranged opposite each other so as to approach each other as they move forward, each of the painting guns and The row spacing of the plurality of rows of section steel is set so that the center of the outer flange surface of the section steel in the adjacent row is located on the extension of the line connecting the upper edge of the section steel flange surface of each row, and A painting instruction sensor set at a predetermined position corresponding to the section steel in the row causes one of the pair of painting guns to project the center of the outer flange surface of the section steel, and the other to project the upper end of the flange of the section steel. An automatic painting method for shaped steel characterized by giving instructions to start and end painting at an extreme position.
