Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an annular mountain coating rod for applying a predetermined coating agent to the surface of a member to be coated, a method of manufacturing the same, and a method for manufacturing the same. The present invention relates to a coating method using an annular mountain coating rod, and more particularly to a technique for eliminating coating unevenness and improving coating performance. 2. Description of the Related Art A helical ridge is provided on an outer peripheral portion of a columnar shape, is disposed substantially parallel to a surface of a member to be coated, and is rotated around an axis while being coated. 2. Description of the Related Art There is known a coating rod which is relatively moved along a surface of a member to apply a predetermined coating agent to a surface of the member to be coated. Conventionally, such a coating rod has been used in which a wire having a predetermined diameter is spirally wound around the outer peripheral surface of a cylindrical rod.
As described in Japanese Patent Application Publication No. 7 (1999), there has been proposed an apparatus in which spiral ridges are integrally provided by rolling. [0005] The coating rod 100 shown in FIG.
This is described in Japanese Patent Application Laid-Open No. -40767, in which the pitch of the ridges 102 in the substantially circumferential direction is narrowed so as to be in contact with each other to have a small pitch P. The coating rod 101 shown in FIG. 6 has a relatively large P because the interval between the ridges 102 in the substantially circumferential direction is widened. The ridges 10 provided on the outer peripheral surfaces of the coating rods 100 and 101
2 has a semicircular cross section and is integrally provided in a spiral shape, and is used, for example, as shown in FIGS. 7 (a) and 7 (b), and is made of a synthetic resin film or sheet. Coating member 1
A coating material 106 of a predetermined material which is a viscous fluid or a liquid substance such as an adhesive, a photosensitive emulsion, or a coating agent is applied to the surface of the substrate 04. In FIG. 7A, a coating rod 100 or 101 is disposed near a surface of a member 104 to be coated in a substantially parallel manner above a feed roller 108 disposed substantially horizontally. Is moved by the feed roller 108 to the right in the drawing, and the coating rod 100 or 101 is moved in the feed direction at a constant rotation speed determined according to the feed speed, as shown by the arrow. The coating agent 106 supplied on the upper surface of the member to be coated 104 is fed in a constant amount by being rotated to apply the liquid to the upper surface of the member to be coated 104 with a predetermined thickness and substantially uniformly. . Also,
FIG. 7B shows a state in which the coating material 104 is caused to travel in a container 112 in which the coating material 106 is stored by a plurality of feed rollers 110, so that the coating material 104 is applied to the surface of the coating material 104. 106 is attached while its container 11
2, a coating rod 100 or 101 disposed in close proximity to the surface of the member to be coated 104 in a substantially parallel manner is rotated at a predetermined rotation speed in a reverse direction as indicated by an arrow, and excess coating is performed. By scraping off the agent 104,
The coating material 106 is applied to the surface of the member to be coated 104 with a predetermined thickness substantially uniformly. FIG. 7A also shows a member 1 to be coated.
04 in the opposite direction to the running direction of the coating rod 100 or 1
The application mode of the coating rod 100 or 101 may be such that the coating rod 106 or the coating rod 106 may be applied substantially uniformly by rotating the 01 to prevent the excess coating agent 106 from passing. It is not limited to 7 (a) and 7 (b). However, since the ridges 102 formed on the outer peripheral surface of such a conventional coating rod 100 or 101 are helical, the member 104 to be coated is Even after a lapse of a predetermined time after the coating agent 106 is applied, the outer peripheral surface of the coating rod 100 or 101 is formed on the surface of the coating layer on which the coating agent 106 is applied, as shown by a broken line in FIG. In addition, there is a problem in that uneven coating formed in relation to the direction of the ridges 102 formed in a spiral shape continues in the lead angle direction of the ridges 102. Such unevenness is caused by local variations in the film thickness, and becomes remarkable when the coating agent 106 has a high viscosity and is difficult to smooth. SUMMARY OF THE INVENTION The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a coating rod which can provide good coating quality with less unevenness in coating film thickness. . Means for Solving the Problems In order to achieve the above object, the gist of the present invention is to provide a method for applying a predetermined coating agent to the surface of a member to be coated. A method for manufacturing a column-shaped coating rod having circumferential ridges provided on a surface thereof, using a rolling die having circumferential ridges having a predetermined lead angle provided on an outer circumferential surface. By rotating the rolling die while pressing it against the outer peripheral surface of the rod material in a state where the axis of the rolling die is inclined by the predetermined lead angle with respect to the axis of the rod material, the outer peripheral portion of the rod material is formed. That is, a number of annular ridges having a lead angle of zero are formed at a predetermined pitch. [0010] In the coating rod with annular ridges manufactured by the manufacturing method of the present invention, when the coating material is applied by rotating the coating material around the axis, Since the ridge provided in the circumferential direction on the outer peripheral surface of the cylindrical coating rod for applying a predetermined coating agent on the surface is constituted by a number of annular ridges having a lead angle of zero. , it applied to Hinuriko member
In the coating layer after the agent has been applied, coating unevenness that continues in the lead angle direction of the ridges does not occur, thereby improving coating quality. According to the manufacturing method of the present invention, the predetermined

A number of annular ridges with zero lead angle are specified on the outer periphery of the material
The rod material formed at a pitch of
It is sent out in one direction while being turned. Preferred embodiments of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a view showing an annular ridged coating rod 10 according to an embodiment of the present invention, and is a front view as seen from a direction perpendicular to an axis. The coating rod 10 for coating with the annular ridge
Is made of metal, has a columnar shape of, for example, about 10 to 30 mmφ, and has on its outer peripheral surface a large number of ridges 12 formed annularly at predetermined intervals in the axial direction. The ridge 12 has a height of, for example, about 10 μm to several hundreds of μm, and has no lead angle (zero) as compared with the related art.
Therefore, the annular ridged coating rod 10 can be referred to as a leadless coating rod. The ridge 12 is formed such that the outer peripheral surface including the peak is a cylindrical surface parallel to the axis. For example, the ridge 12 is set within a range of 0.1 mm ≦ P 1 ≦ 3.0 mm.
It is formed in an annular or ring-shaped at intervals of pitch P 1. The cross section of the ridge 12 has a peak-like shape or a semi-circular shape, but may have a trapezoidal shape with a flat peak. Further, the shape of the concave portion, that is, the valley portion 18 between the ridges 12 may be various shapes according to the material to be applied, that is, the physical properties of the coating agent. The annular ridged coating rod 10 is disposed substantially parallel to the vicinity of the surface of the member 104 to be coated, is rotated about an axis, and relatively moves along the surface of the member 104 to be coated. The member to be coated 1
A predetermined coating agent 106 is applied to the surface of the substrate 04 substantially uniformly. For example, in the coating (coating) apparatus shown in FIGS. 7 (a) and 7 (b), the coating member 104 is disposed in place of the coating rod 100 or 101, and is rotated about an axis. A predetermined coating agent 106, which is a viscous fluid such as an adhesive, a pressure-sensitive adhesive, a photosensitive emulsion, a coating agent, or the like, is applied to the surface of the substrate with a predetermined thickness in a substantially uniform manner. Such a coating rod 10 with an annular ridge is provided with:
For example, it is manufactured by the rolling apparatus 20 shown in FIGS. The rolling device 20 includes a pair of rolled round dies 22 and 24 for performing rolling by pressing the cylindrical rod material 26 from both sides, and for supporting the rod material 26 being rolled from below. And a support member 28. FIG. 2 is a front view of the rod material 26 viewed from the axial center direction, and FIG.
2 is a right side view of FIG. 2, and FIG. 4 is a plan view of FIG. [0017] On the outer peripheral surface of the rolling die 22, 24, both substantially intervals of the same pitch rolling teeth 30 of the cross-sectional shape and the pitch P 1 corresponding to the shape of the recess 18 between the ridges 12 A pair of the rolling dies 22 and 24 are formed in a spiral so as to be separated from each other in the axial direction so that the lead angle θ is about 0.04 ′, for example, as shown in FIGS. 3 and 4. The teeth 30 are rotatably disposed such that the tooth trace direction of the portion of the teeth 30 that contacts the rod material 26 is in a direction perpendicular to the axis of the rod material 26, that is, in FIG. That is, the rotation axis A of the rolling die 22 located on the right side in the traveling direction of the rod material 26 and the rotation axis B of the rolling die 24 located on the left side in the traveling direction of the rod material 26.
And a pair of rolling dies 22 and 24 are disposed so that they can be inclined in opposite directions by a lead angle θ with respect to a plane including the rotation axis C of the rod material 26. 3 and 4, the inclination of the rotation axis of the rolling dies 22, 24 is emphasized in FIGS. The rolling apparatus 20 constructed as described above
When the pair of rolling dies 22 and 24 are driven to rotate in the direction indicated by the arrow in FIG. 2 or FIG. 4, an annular ridge 12 having a lead angle θ of zero is formed on the outer peripheral surface of the rod material 26. While being rolled, the rod material 26 is fed to the left in FIG. 2 while rotating about the axis in the direction indicated by the arrow in FIG. 2 or FIG. The annular ridged coating rod 1 is cut into a predetermined length by a device (not shown).
0 is obtained. Note that one of the pair of rolling dies 22 and 24 may have a cylindrical surface without the rolling teeth 30. Here, the annular mountain coating rod 10 as described above is applied to the coating apparatus shown in FIGS. 7 (a) and 7 (b) by applying a coating agent 106 on the surface of the member 104 to be coated with a predetermined thickness. When used for uniform application, the lead angle of the ridge 12 formed on the outer peripheral surface thereof is zero, so that even if the application is performed at a high speed, coating unevenness does not occur. Incidentally, when a coating rod on which a spiral ridge 12 having a lead angle θ is formed is used, for example, 45 mm is used.
When the coating is performed at a relatively high speed of about 0 m to 800 m / min, the direction of the lead angle θ is generated in the flow of the entrapped air. The coating unevenness visually recognized in the direction is formed. While the embodiment of the present invention has been described with reference to the drawings, the present invention can be applied to other embodiments. For example, the ring-shaped coating rod 10 of the above-described embodiment is suitable for a case where a predetermined coating agent 106 is thinly applied to the surface of a synthetic resin film or sheet as the member 104 to be coated. However, it can also be used when applying the coating agent 106 to the member to be coated 104 other than such a film or sheet. As a coating agent,
For example, a liquid substance having a predetermined fluidity and viscosity is suitably used, but a powdery substance or the like can be applied as a coating agent. Further, the above-mentioned coating rod 10 for coating with an annular ridge is described.
Has a diameter of about 10 mm to 30 mm,
1 pitch P 1 is 0.1mm to 3.0mm approximately, the height of the ridge 12 is within a range of about 10μm to several hundreds [mu] m, but not necessarily limited to that range. Although the lead angle θ of the pair of rolling round dies 22 and 24 is about 0.04 ′ (minute), it is not always necessary to set that value. Further, the coating rod 10 for coating with an annular crest according to the present invention.
Is used for coating, for example, in the mode shown in FIGS. 7 (a) and 7 (b), but may be used in other modes. The embodiments of the present invention have been described in detail with reference to the drawings.
