塗料が噴射され、塗装を行う。The carrier 7 of the spray gun 6 reciprocates in the width direction of the steel plate 20 to be painted, and the spraying on the other side of the steel plate 2 to be painted is 0, taking the starting side as an example, and the striker 7a of the key carrier 7 One side fits the painting width setting device
When detected by the other paint instruction sensor 5a of the paint sprayer 5, a counting circuit is activated to count the moving distance of the carrier 7, and when the preset delay distance is reached, the paint sprayer sends a signal and starts the machine. After 41 turns of distance L2 caused by the electrical control delay, paint is sprayed from the spray gun 6 to perform painting.

Mechanical and electrical control delays are caused by automatic painting machine 3.
The delay distance I・2 is usually about 200~

する。Then, on the paint stopping side, the above-mentioned spraying is carried out in the same manner as on the starting side, and when the other side of the striker 73 is detected by one painting instruction sensor 5a of the painting width setting device 5, the counting circuit is activated. Count the distance traveled by carrier 7,
When a preset delay distance 171' is reached, a paint stop signal is sent, and after the paint has traveled the distance T, 2' caused by the mechanical and electrical control delay, the spraying of paint is stopped.

行われる。Further, the reciprocating distance of the carrier 7 is always constant, corresponding to the maximum width of the steel plate 2 to be coated that can be coated by the automatic coating machine 3, and for example, when coating a steel plate 2 with a narrow width. In this case, the reciprocating distance of the carrier 7 is the same as when painting the steel plate 2 with the maximum width, but the spraying distance of the paint is increased so that the so-called spray gun 6, which does not spray paint, has a longer empty running distance. Start and stop control is performed.
