Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method and an apparatus for uniformly applying a viscous substance such as grease to a surface to be coated of a work.

[0002]

2. Description of the Related Art Conventionally, grease has been applied to the outer diameter surface of a cylindrical work for the purpose of lubrication, rust prevention and the like. In this case, conventionally, apply grease to your fingertips,
A method of applying the grease to a predetermined surface of the work has been adopted.

[0003]

However, according to the conventional method, when grease is applied to a large amount of work, the workability is poor, and the worker's hands are contaminated.

Therefore, it is an object of the present invention to provide a coating method and a coating apparatus which can efficiently coat a viscous substance such as grease.

[0005]

An invention of a coating method for solving the above-mentioned problems is to rotate a work having a cylindrical surface to be coated at a fixed position and to rotate a rotary shaft parallel to the rotary shaft of the work. Bring the coating roller having close to the surface to be coated,
A viscous substance is supplied to the application surface while the application roller is rotated, and the viscous substance is applied to the outer peripheral surface of the work by the application roller.

Further, the invention of a coating device for solving the above-mentioned problems is a work supporting and rotating device for supporting a work having a cylindrical surface to be coated and rotating the work at a fixed position,
The coating roller device has a rotation axis parallel to the work supporting and rotating device, and a viscous substance supply device for supplying a viscous substance to the coated surface of the work.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIGS. 1 to 3 show an embodiment of the invention of a coating apparatus and an embodiment of an apparatus used for carrying out a coating method.

This coating device comprises a work supporting and rotating device 1,
It is composed of a coating roller device 2 and a viscous material supply device 3. The work supporting / rotating device 1 has a vertical guide rod 4 having a vertical movement function and a driven rotation function, and a drive spindle 5 provided coaxially above the guide rod 4.

The guide rod 4 has a collar 6 and is inserted into the center hole 8 of the work 7 from below. Above brim 6
Is applied to the step portion 9 of the central hole 8 to support the work 7 in a rotatable state. The portion of the guide rod 4 above the brim 6 is rotatably inserted into the central hole 8 with a minimum clearance, and positions the workpiece 7 in the radial direction.

Work 7 supported by the guide bar 4
Is pressed against the lower surface of the drive spindle 5,
While sliding on the upper surface of the collar 6, it rotates about the guide rod 4 and the work 7 is restrained by this. When the drive spindle 5 rotates, the guide rod 4 is driven to rotate via the work 7.

In the coating roller device 2, a coaxial coating roller 11 is attached to the upper end of a vertical rotary shaft 10, and the rotary shaft 10 is mounted on the rotary shaft 10.
Is rotatably supported by a support arm 12, and a belt 16 is hung between a pulley 13 at the lower end of the rotary shaft 10 and a pulley 15 of a drive unit 14. The coating roller 11 is arranged at a position approaching the cylindrical coating surface 17 of the work 7 with a predetermined gap c. In addition,
The support arm 12 can move freely in the horizontal plane.

The viscous material supply device 3 is composed of the coating roller 1 described above.
Is provided close to the coated surface 17 on the side opposite to 1,
The viscous substance 19 is ejected from the nozzle 18 onto the surface 17 to be coated (see FIG. 2).

The coating apparatus of the embodiment is as described above, and the operation of the apparatus will be described below.

The center hole 8 of the work 7 is inserted into the upper end of the guide rod 4 at a predetermined position, the guide rod 4 is raised to a predetermined height, and the work 7 is pressed against the lower surface of the drive spindle 5.

Further, the support arm 12 of the coating roller device 2
Is moved between horizontal planes to move the application roller 11 to the work 7
The surface 17 to be coated is approached with a gap c.

The above drive spindle 5 and coating roller 1
When the viscous substances 19 are sprayed from the nozzle 18 of the viscous substance supplying device 3 at a constant interval while rotating 1 in mutually opposite directions, the viscous substances 19 adhere to the coated surface 17 of the work 7 by a constant amount, When rotating with the work 7 in this state, the application roller 11 located on the opposite side of the viscous material supply device 3 is contacted and stretched, and is uniformly applied to the surface 17 to be coated.

When the coating on the surface 17 to be coated is completed, the coating roller 11 and the guide rod 4 are returned to the initial state and the work 7 is removed from the guide rod 4 by the procedure reverse to the above.

If there is a step on the surface 17 to be coated,
The coating roller 11 also has a stepped portion according to its shape.

[0019]

As described above, according to the coating method and coating apparatus of the present invention, a viscous substance such as grease can be efficiently applied to the surface to be coated of the work without depending on the operator's hand, and a uniform thickness can be obtained. Can be applied.
