It's being used. In such a panel construction method, a panel material manufactured by attaching a face material such as plywood to a surface of a square frame-shaped base frame made of a wooden square material is used. Then, when manufacturing the panel material, a coating material such as a primer is applied in advance to a square material constituting the base frame by a coating device in order to enhance the adhesiveness of an adhesive or the like.

FIG. 3 shows a coating line in which a conventional coating device 60 is installed, and FIG.
2 is a cross-sectional view of the application roller 70 constituting the image forming apparatus. 3 and 4, the coating device 60 includes swing arms 61 that approach and separate from each other, and a tip end of each swing arm 61 is provided with a rotatable coating roller 70. These application rollers 70 press both side surfaces 91 of the square member 90 fed in the direction of the arrow by the feed device 80 by the spring force of a spring 62 provided between the swing arms 61, and the square member 90.
With the feed, the frictional force rotates.

Each coating roller 70 is composed of a core 71 having a vertical rotating shaft 72 and a sponge-like impregnating portion 74 covering an outer peripheral surface 73 of the core 71. In the application roller 70, the liquid primer supplied through the hose 63 flows into the core 71 from the upper end of the rotating shaft 72, and then flows out of the plurality of round holes 75 provided substantially over the entire outer peripheral surface 73. Out of the impregnated portion 74, seeps out of the surface of the impregnated portion 74, and

In such a coating apparatus 60, the impregnating portion 74 constituting the coating roller 70 has a vertical dimension larger than the vertical dimension of the side surface 91 because of the necessity of considering the vertical runaway of the rectangular piece 90. In this case, the square bar 90 is brought into contact with the approximate center of the vertical direction. In addition, as the sponge-like impregnated portion 74, a tubular integrated body was used.

[0006]

However, in the above-described coating apparatus, most of the rectangular material is brought into contact with the central portion of the impregnated portion, so that only the central portion is worn out or deformed. In such a case, the impregnated portion has to be replaced as a whole since the impregnated portion is an integral body even though the abrasion and deformation hardly occur except for the central portion. For this reason, there was a problem that the impregnated part could not be used effectively. In addition, since a round hole outlet for discharging the primer is provided over substantially the entire area of the core, the primer flows out in a larger amount as the lower outlet, and the primer is not uniformly applied to the square material. there were.

An object of the present invention is to provide a coating apparatus that can effectively use an impregnated section.

It may be provided. In such a case, the application agent is impregnated into the impregnating portion 12 while flowing out and flowing down from the upper side of the core 11, so that the impregnating portion 12 is surely impregnated in the vertical direction. Therefore, even if the application roller 10 that rotates on the rotation shaft 13 along the vertical direction is used,
No coating unevenness occurs.

In the coating apparatus of the present invention, the core 11
It is preferable that the outflow port 17 is formed in a slit shape elongated in the vertical direction. In such a case, even if impurities are mixed in the coating agent, clogging of the outlet 17 is less likely to occur.

Further, in the coating apparatus of the present invention, the core 11
A liquid reservoir 15A for storing the coating agent may be provided below the outflow port 17 in the inside. In such a case, impurities in the coating agent are submerged in the liquid reservoir 15A, and

[0014]

An embodiment of the present invention will be described below with reference to the drawings. The coating apparatus according to the present embodiment forms a base frame by framing a wooden square, and applies a primer to the square when manufacturing a panel material for building by attaching a face material to the base frame. A coating device 60 shown in FIG.
The difference from the first embodiment is that the application roller 10 shown in FIGS. 1 and 2 is used as the application roller. Therefore, for the sake of simplicity, the description of the same components as in the related art will be omitted, and only the application roller 10 will be described in detail below.

1 and 2, the coating roller 10 is
It comprises a stainless steel core 11 and a sponge-like impregnated part 12 which covers the outer peripheral surface of the core and is detachable. The core 11 has a vertical rotating shaft 13 having a screw portion 13A at an upper portion. The rotating shaft 13 is inserted into a bearing of a swing arm (not shown), and is rotatably mounted by a nut screwed into the screw portion 13A. It is supposed to be. An upper flange portion 14 is provided below the rotating shaft 13, and a bottomed cylindrical portion 15 is integrally provided on a lower surface of the upper flange portion 14 by welding or the like.

A primer as an application agent flows into the inside of the cylindrical portion 15 from an application agent inflow passage 16 provided through the rotating shaft 13 and the upper flange portion 14. A vertically long slit-shaped outlet 17 is provided on the outer peripheral surface on the upper side of the tubular portion 15 so that the primer accumulated in the tubular portion 15 overflows from these outlets 17 and flows out. I have. That is, the cylindrical portion 1
The lower side of the outlet 17 in 5 is a liquid reservoir 15A in which the primer is always stored, and impurities and the like in the primer sink down in the liquid reservoir 15A.

Further, a screw hole 18A is provided in the bottom portion 18 of the cylindrical portion 15, and a lower flange member 20 is attached to a lower surface of the bottom portion 18 by a bolt 19 screwed into the screw hole 18A. The upper flange 14 and the lower flange member 20 vertically hold the impregnated portion 12 inserted into the cylindrical portion 15, and the screw hole 18A functions as a drain hole, and the impurities settled in the liquid reservoir 15A. Is discharged.

On the other hand, the impregnated portion 12 is formed by stacking a plurality of felt ring members 21 one above the other, so that the impregnated primer seeps out from the outer surface.

In this embodiment, of the ring members 21 constituting the impregnated portion 12, only the central ring member 21A is used, and the square lumber as an object to be coated is large (see FIG. 3).
Contact, these ring members 21A are deformed as shown by the two-dot chain line in FIG. In such a case, after removing the lower flange member 20, the deformed ring member 21A is rearranged on the upper side or the lower side, and the other ring member 21 with little deformation is positioned on the center side. The ring member 21 with little deformation is brought into contact with the square bar. However, each of the deformed ring members 21A may be replaced with a completely new ring member, and whether to replace or rearrange may be appropriately determined in the implementation.

According to this embodiment, the following effects can be obtained. That is, since the impregnated portion 12 is formed from the plurality of ring members 21, when the impregnated portion 12 is worn or deformed, the ring member 2 in the worn or deformed portion is used.
Only 1A needs to be replaced, and waste such as replacing the entire impregnated portion 12 can be eliminated. This can reduce the running cost of the coating device.

Further, since the outflow port 17 is provided only on the upper side of the cylindrical portion 15, the primer flowing out from the upper side of the cylindrical portion 15 flows down and is surely impregnated into the impregnating portion 12. Thus, the primer can be uniformly exuded in the vertical direction of the impregnated portion 12.

Since the outlet 17 is in the form of a slit extending in the vertical direction, impurities in the primer are removed from the outlet 1.
Even if it accumulates at the lower part of 7, it is possible to maintain a sufficient amount of outflow of the primer, and it is possible to prevent clogging which may hinder the outflow state. Furthermore, since the lower side of the outlet 17 is the liquid reservoir 15A, impurities are removed from the liquid reservoir 15A.
A can be sunk in the lower side of A, and clogging of the outflow port 17 can be suppressed more reliably. At this time, the bottom 1
Since the screw hole 18A of 8 also serves as a drain hole, impurities can be easily removed when the ring member 21 is removed, and maintenance of the application roller 10 is also easy. And, since clogging is suppressed by these things, there is no need to remove impurities using a large-scale filter, and the entire apparatus can be configured at low cost, especially when the primer that has flowed down is circulated and reused. It is effective for etc.

Further, since each of the ring members 21 constituting the impregnated portion 12 is made of felt, the wear resistance can be improved. In addition, due to the strong stiffness, even if it is deformed, the deformed portion will take time. Since the old one is restored, the ring member 21 removed or rearranged by deformation can be used again, which is more economical.

Further, since the core 11 is made of stainless steel, the corrosion resistance can be improved, and the core 11 can be used for a long time.

By using such an application roller 10 in an application device for applying a primer to a square material, it is possible to maintain good quality in the application process of the panel material.

It should be noted that the present invention is not limited to the above-described embodiment, but includes other configurations that can achieve the object of the present invention, and also includes the following modifications and the like.
For example, in the above-described embodiment, the ring member 21 is made of felt. However, the ring member 21 is not particularly limited to felt and may be made of polyurethane or the like having many open cells. However, the effects described above can be obtained by using felt.

In the above embodiment, the core 11 is made of stainless steel. However, the material of the core 11 is arbitrary, and may be appropriately determined in consideration of the components of the coating agent used. The liquid reservoir 1 is provided in the cylindrical portion 15 of the core 11.
5A is provided, but the present invention includes a case where the liquid reservoir 15A is not provided, that is, a solid cylindrical shape on the lower side of the outlet 17 is included in the present invention. However, by providing the liquid reservoir in the core, the above-described effect that clogging can be more unlikely to occur can be obtained.

The outlet is not limited to a vertical slit, but may be a round hole or a slit that is long in the horizontal direction (long in the rotation direction). However, by forming the inflow port in a vertical slit shape, the above-described effect can be obtained. However, the inlet is not essential to the present invention. For example, when the coating apparatus of the present invention is of a handy type in which the impregnated part is immersed in a coating agent, the inlet is unnecessary.

Furthermore, in the above embodiment, a primer is used as a coating agent. However, as a coating agent, for example, a preservative, an adhesive, a sealer, a paint, or the like can be used in addition to the primer.

Further, in the above embodiment, the coating device is applied to a square material constituting a panel material for a building, but the coating device of the present invention can be applied to all other types. At this time, peripheral devices such as a feeding device and a drying device can be omitted depending on the object to be coated.

[0031]

As described above, according to the present invention, since the impregnated portion of the application roller is formed by a plurality of ring members, when the impregnated portion is worn or deformed,
