布用ローラに関する。Detailed Description of the Invention (Field of Industrial Application) The present invention relates to a coating roller used to apply various paints, liquid adhesives, etc. The present invention relates to a coating roller that applies coating by pressing the roller against the surface to be coated and rolling it.

性が非常に悪いという問題がある。(Prior Art) One of the simplest coating rollers that has been widely used in the past is one in which the coating roll is rotatably attached to a support shaft. However, such a coating roller has a problem in that the coating workability is very poor because the entire coating roll must be frequently immersed in a coating liquid tank to replenish the liquid.

量が大きくなるといつた問題があつた。 On the other hand, as a coating roller that can automatically replenish the coating liquid, a coating roll cylinder that can freely rotate around the coating liquid delivery pipe connected to the liquid feed pump is attached, and the above-mentioned coating roller located inside the coating roll cylinder It is known that a plurality of coating liquid outflow holes are provided in the outlet pipe at equal intervals so that the coating liquid flowing out from these outflow holes leaks outward from the inner surface of the coating roll tube. However, in the case of such conventional coating rollers, the coating liquid is more likely to come out due to high liquid pressure from the outlet hole located closer to the coating liquid introduction side of the outlet pipe, so the amount of coating liquid impregnated on the coating roll surface is This tends to create a slope in the width direction, resulting in uneven coating, and depending on the viscosity of the coating liquid, droplets may fall from the area near the introduction side and stain the surrounding area.
To avoid this, conversely, blurring occurs in the part far from the introduction side, making it difficult to adjust the pressure.Furthermore, the coating liquid remaining inside the coating roll cylinder and the outlet pipe during liquid feeding is transferred to the coating roller. When the roller is tilted, the coating liquid forms droplets and falls off, and in addition, the entire space inside the coating roll tube is filled with the coating liquid, which increases the overall weight.

る。 Further, the coating liquid supplying member 4 includes a bag-shaped portion 4a formed from a single plate of synthetic resin or elastic metal and having an approximately teardrop-shaped cross section. A slit-like opening 10 having a length spanning the entire effective coating width is formed, and this opening 1
Both side end pieces 4b, 4b forming the edges of 0 extend outwardly in a projecting manner. Further, the openings at both ends of the bag-shaped portion 4a are sealed by end plates 4c, 4c which are attracted and fixed by a bolt 11a inserted into the bag-shaped portion 4a and a nut 11b screwed onto the bolt 11a. Further, a support collar member 12 made of a single plate of synthetic resin or the like is fitted around the outer periphery of the bag-like portion 4a, and the entire coating liquid supply member 4 is linked to this support collar member via a spring shaft 5 fixed at one end. It is supported in a swingable state via the connecting portion 5c. Therefore, the spring shaft 5 is biased by the elastic force of the built-in coil spring 13 in the direction in which the inner cylinder part 5a and the outer cylinder part 5b are separated, that is, in the direction of extension, and the application liquid replenishing member 4 is pushed into the slit. Both side end pieces 4b, 4b, which are the edges of the shaped opening 10, are pressed against the outer surface of the application roll 3 in a state of elastic sliding contact. On the other hand, the slit-shaped opening 10 is set to open when the internal pressure of the bag-shaped portion 4a exceeds a certain level due to the elasticity of the materials of the coating liquid supply member 4 and the support collar member 12.

た落ちして周囲を汚すという惧れがない。 In the coating roller configured as described above, the coating liquid that has been force-fed by the liquid pump through the connecting pipe 7 and the coating liquid introduction pipe 6 fills the bag-shaped portion 4a of the coating liquid supply member 4, and When the internal pressure reaches a certain level, the slit-shaped opening 10 opens, and the liquid flows uniformly over the entire effective coating width onto the outer surface of the coating roll 3 and penetrates into the impregnating material layer 3b. A predetermined coating can be performed by rolling the coating roll 3 while pressing the surface of the coating onto the surface to be coated. In this case, the amount of coating liquid impregnated into the impregnating material layer 3b of the coating roll 3 is uniform without any gradient in the width direction, so that uneven coating does not occur. Also, from this point of view, if the liquid feeding pressure is set to a level that does not cause blurring, droplets will be prevented from falling during application.
In addition, there is little influence from differences in the viscosity of the coating liquid, and the liquid feeding pressure can be adjusted very easily. Furthermore, when liquid feeding is stopped, the slit-shaped opening 10 is automatically closed due to the decrease in the internal pressure of the bag-like part 4a, so even if the application roller is tilted, the flow inside the bag-like part 4a and connected thereto will be closed. The coating liquid in the path does not flow out, so there is no risk of droplets dripping down and staining the surrounding area.

い。 In addition, by configuring the coating roller to be detachable from the gripping gun etc. via the adapter part as in the above-mentioned embodiment, conditions such as the surface texture of the surface to be coated, the coating film thickness, etc., and the degree of wear on the roll surface can be adjusted. Although there is an advantage that the application roller can be replaced depending on the situation, a fixed method may also be used. Further, the length of the coating liquid supply member and the slit-like opening may be shorter than the length of the coating roll.

しに本発明を適用した構造に改造できる。(Effects of the Invention) According to the coating roller according to the present invention, the coating liquid uniformly flows out from the slit-shaped opening of the coating liquid supply member and is impregnated into the coating roll, so that the amount of impregnation in the coating width direction is reduced. The coating is uniform and can be applied without uneven coating, blurring, or falling droplets, and the surface to be coated becomes beautiful and the coating work is easy.Also, there is little influence from differences in the viscosity of the coating liquid, and the liquid delivery pressure can be adjusted. becomes easier. Furthermore, while liquid feeding is stopped, the slit-like opening closes naturally due to the decrease in internal pressure, so even if the coating roller is tilted, the remaining liquid in the coating liquid supply member and in the path connected to it will not leak out. There is no fear that droplets will fall and contaminate the surrounding area. In addition, in the present invention, the coating liquid is directly supplied to the outer surface of the coating roller to impregnate it, and there is no large-capacity liquid storage space within the coating roller, so the entire structure can be made lightweight, and the coating liquid supply member Since the structure of the liquid supply section including the liquid supply part is simple, it can be manufactured at low cost, and the present invention can be applied to the structure of existing coating rollers, such as manual coating rollers using an immersion replenishment method, without major design changes. Can be modified.
