によル決定される。Conventionally, a method in which a member to be coated is immersed in a paint and coated by pulling it up in a direction perpendicular to the liquid level is well known as a dip coating method. When applying using this application method,
The thickness of the coating film is determined by the viscosity of the coating material and the rate at which the object to be coated is pulled up.

かった。In other words, the higher the viscosity, the thicker the film (for example, the faster the lifting speed is, the thicker the film is). It is easy to fluctuate.Also, when the amount of paint decreases, the viscosity tends to expand and fluctuate even when the shortage is refilled.In this way, when the viscosity fluctuates, the thickness of the paint film can be kept at a constant value. Coating in this manner requires new viscosity measurements and setting of pulling speed conditions, so the coating operation had to be interrupted.

呼ばれるものを使用することができる。Viscosity measurement is usually performed using a rotational viscometer, bubble viscometer, capillary viscometer, cup viscometer, etc., but for easier automatic measurement, a rotor (rotor) dipped in the coating liquid is used.
It is best to rotate the motor by a motor and measure the load change. In other words, there is a method of rotating the rotor at a constant speed and measuring the torque, a method of measuring the change in the current of the motor, and a method of rotating a DC motor with a constant current and measuring the change in rotation speed. However, the present invention does not relate to a specific method of measuring viscosity (other methods can also be used.The device for controlling the coating machine uses a microcomputer, a personal computer, and a device called a minicombi motor. can do.

で上下動する。FIG. 1 shows an example of a coating device used in the coating method of the present invention. A coating film 15 is formed by immersing a cylindrical member 1 to be coated, which is provided with a lid 4 at the bottom and top to prevent paint from entering, into a coating tank 2 containing a coating material 628 and pulling it up. The upper rod 6 of the workpiece is connected to the endless belt 1.

利である。In addition, in the dip coating method, a so-called overflow method is employed in which the coating material 3 is constantly allowed to overflow from the coating tank 2 in order to apply the coating film evenly and uniformly. This method is advantageous because even if one paint is made by dispersing pigments in a resin, the composition can be made uniform.

The data regarding the optimum pulling speed is selected and sent to the drive motor 5 via the D/A converter 47.
The signal is transmitted to a variable resistor 44 for controlling the rotational speed of the motor and a step motor 45 for rotating the variable resistor. This step motor reeds so that the angle changes by 1 degree, and thereby the coating speed can be changed.
