When the cylinder compressed air open / close valve 76 is opened, compressed air is supplied to the air cylinder 31, and the gun holder 21 and the automatic injection gun 60 move to the left along the X-axis direction (see Fig. 8). Here, the moving speed of the automatic injection gun 60 can be selected by operating the speed cone 77.

When the detection signal is input from the injection position detection sensor 32 on the right side while the automatic injection gun 60 moves to the left along the X-axis direction, the control unit 23 supplies compressed air to the automatic injection gun 60. The dry compressed air open / close valve 75 is controlled.

When compressed air is supplied to the automatic injection gun 60, paint is injected from the injection nozzle 62.

Next, when the automatic injection gun 60 moves to the left along the X-axis direction and a detection signal is input from the injection position detection sensor 32 on the left side, the control unit 23 enters the automatic injection gun 60. The dry compressed air open / close valve 75 is controlled to block the supplied compressed air. As a result, paint spraying by the spray nozzle 62 is stopped.

Next, when the automatic injection gun 60 moves to the left along the X-axis direction, and a detection signal is input from the movement limit position detection sensor 33 on the left side, the control unit 23 enters the air cylinder 31. The cylinder compressed air opening and closing valve 76 is controlled to block the compressed air supplied thereto.

When the compressed air supplied to the air cylinder 31 is blocked, the gun holder 21 and the automatic injection gun 60 are also stopped.

Next, the control unit 23 opens another cylinder compressed air open / close valve 76 so that the compressed air is supplied to the air cylinder 31 through the other compressed air pipe.

When the other cylinder-compressed air open / close valve 76 is opened, compressed air is supplied to the air cylinder 31, and the gun holder 21 and the automatic injection gun 60 move to the right along the X-axis direction (see Fig. 9). .

If the detection signal is input from the injection position detection sensor 32 on the left while the automatic injection gun 60 moves to the right along the X axis direction, the control unit 23 supplies compressed air to the automatic injection gun 60.

Control, and generates an alarm sound through a predetermined alarm device. The operator changes the attachment position of the specimen plate 202 attached to the specimen plate attachment column 22 upward and performs automatic painting again.

 On the other hand, when the painting work on the sample plate 202 is completed, the operator separates the paint cup 201 from the automatic injection gun 60, and then attaches the paint cup containing the thinner to the automatic injection gun 60.

Next, when the operator operates the dry cleaning button 54, the control unit 23 controls the dry compressed air open / close valve 75 so that the compressed air is supplied to the automatic injection gun 60.

When compressed air is supplied to the automatic spray gun 60, thinner is sprayed from the spray nozzle 62 to remove paint residues remaining in the paint flow path and the spray nozzle 62.
