Description

  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coating roller and a coating method capable of easily coating only convex portions of an object having irregularities.

  Conventionally, for example, if it is desired to paint only a convex portion on an outer wall having irregularities, the paint is applied to a roller brush made of short hairs, and the roller brush is applied to the convex portion surface with a slight force so that the paint does not adhere to the concave portion. The painting was done by rolling lightly while making contact.

  However, in the above-mentioned convex part coating by the short-haired roller brush as described above, unless the operator is very skilled, it is necessary to finish the entire object to be coated while continuously maintaining the fine adjustment of the roller brush on the convex part surface. In many cases, unintended adhesion of paint to concave portions and uneven boundary portions become patchy, resulting in impaired design, resulting in repair work.

  On the other hand, it is empirical that if paint is applied to a smooth roller or the like that hardly holds paint inside and a convex part such as an outer wall with irregularities is painted, paint adhesion to concave parts can be prevented and boundary parts of irregularities can be clearly expressed. However, since the coating material was not held by the roller, the range in which the coating could be performed by one operation was extremely narrow, and was unsuitable for the coating of convex portions.

  In such a situation, for example, a coating tool according to Patent Literature 1 (FIG. 5 in the literature) discloses a configuration in which a sponge roller and a smooth roller are connected via a locking tool locked to a grip. .

JP-A-3-89970

  Certainly, when a convex part such as an outer wall having irregularities is painted using the painting tool according to Patent Document 1, by supplying the paint to the sponge roller, one operation is performed until the paint transferred to the smooth roller becomes insufficient. It is excellent in that it can perform painting over a wide area.

  However, in the coating tool according to the present technology, in order to supply the paint to the sponge roller, only the sponge roller cannot be immersed in the paint in the container filled with the paint, so that a separate paint container having a small outlet is formed. It must be used to apply the paint directly to the sponge roller or to dip the paint with the sponge roller in a container filled with paint together with a smoothing roller.

  In the former case, it is very complicated to apply the paint directly to the sponge roller every time the painting work is performed, and even if a large amount of paint adheres unintentionally, squeeze the paint with a roller net etc. It is difficult to adjust.

  Also, in the latter case, more paint than necessary adheres to the smoothing roller. Since the amount must be adjusted, it is very complicated, and even if a large amount of paint adheres unintentionally to the sponge roller, it is difficult to adjust the amount by wiping the paint with a roller net etc. is there.

  In addition, when using smooth rollers with different hardness according to the material or surface condition of the object to be coated, or when using sponge rollers with different amounts of paint holding, separate coating tools that make an appropriate combination of both rollers There is a problem that multiple preparations are required.

  Further, in a situation where only the smoothing roller or only the sponge roller is required to be used alone for rework or a separate operation, the coating tool according to the present technology cannot cope with the situation.

  Moreover, in the coating tool according to the present technology, since the contact pressure of the sponge roller (the gap between the two rollers) cannot be adjusted with respect to the smooth roller, it is intended that one or both of the two rollers deteriorate and the contact pressure changes. However, there is a problem that a coated film cannot be formed.

  The present invention has been made in view of the above circumstances, and can easily coat only a convex portion of an object having irregularities, and can flexibly cope with various situations of the object to be coated.

  When the gripper 62 is gripped as the coating roller 1 or when the coating body gripper 26 is engaged by the engaging portion 64, the tip of the transfer / separation portion 41 is moved upward so that the regulating piece 9 of the frame 3 is moved upward. Alternatively, the stay 42 (the shaft portion 46) may be biased downward so that the application main body portion 2 and the transfer / separation portion 41 are integrated with each other more firmly.

  A substantially L-shaped hook 29, which is bent forward and is viewed from the side, is also vertically provided on the frame 3, which is the lower end of the second auxiliary guide portion 11b, and is hooked on a side wall of a container or the like filled with paint. It is possible to keep.

  The coating main body 2 formed in this way can be used as a coating roller 1 with the transfer separation unit 41 mounted thereon, or can be used as a single unit in a coating operation.

  As described above, the coating roller 1 according to the present embodiment is a coating roller 1 including the coating main body 2 and the transfer separation unit 41 detachable from the coating main body 2. A frame body 3, an application roller 18 having a smooth surface rotatably supported at one end of the frame body 3, and an application body gripper 26 projecting from the other end of the frame body 3. , And a transfer separation portion 41 includes a stay 42, a transfer roller 48 rotatably supported at one end of the stay 42, and a transfer separation gripping portion protrudingly provided at the other end of the stay 42. 52, a guide portion 4 for guiding, placing and positioning the stay 42 is formed on the frame 3, and the transfer separation portion 41 is positioned and mounted on the guide portion 4 of the coating main body 2. Thus, the transfer coating unit 60 in which the transfer roller 48 is close to the coating roller 18 is configured. Since the transfer separation gripping portion 52 is superposed on the coating main body gripping portion 26 and these are integrated to form the gripping portion 62, the transfer separation portion 41 can be easily removed from the coating main body portion 2, and the transfer separation portion 41 If only the transfer roller 48 is immersed in the paint in the container filled with the paint, the paint can be easily adjusted to an appropriate amount by squeezing the paint with a roller net or the like. Work can be performed easily.

  In addition, if the transfer / separation unit 41 is removed from the coating roller 1, the coating main body unit 2 and the transfer / separation unit 41 can be used independently for rework or separate work.

  Furthermore, when using the application roller 18 having a different hardness according to the material or surface condition of the object to be coated, or using the transfer roller 48 having a different amount of the paint held, the two rollers 18 and 48 can be easily combined in an appropriate combination. be able to.

  Further, since the guide portion 4 includes the guide groove 5 for guiding the stay 42 and the regulating piece 9 for regulating the vertical movement of the stay 42, the transfer separation portion 41 is formed with respect to the coating main body 2. It can be mounted while easily positioning.

  Further, since the guide portion 4 has the contact pressure adjusting portion 13 that allows the transfer roller 48 to move forward and backward with respect to the application roller 18, the contact pressure of the transfer roller 48 with respect to the application roller 18 can be easily adjusted. Can be.

  Further, the coating roller 1 composed of the coating main body 2 and the transfer separation unit 41 can be used alone because the coating main body gripping part 26 and the transfer separation gripping part 52 are formed with an engaging part 64 that integrally engages with each other. It can be easily handled as a tool.

  Next, an example of a method of coating only the convex portions of the uneven surface of the outer wall of the building to be coated using the coating roller 1 according to the above-described embodiment will be described below. The description of the operation of the primer and the like and the repair work of the joint is omitted.

  First, the outer wall, which is the object to be coated, is washed by high-pressure washing or the like to remove dirt on the surface. Then, a portion where the paint is not to be adhered is covered with a covering material such as vinyl and fixed with a masking tape or the like and cured.

  Further, the transfer separation section 41 is removed from the coating roller 1, the transfer roller 48 is immersed in the paint filled in the container, and the paint contained in the transfer roller 48 is squeezed by a roller net or the like installed in the container. Adjust the holding amount of.

  In this case, if the coating main body 2 is hooked on the outer wall of the container using the hook 29, the transfer / separation unit 41 can be easily handled, and in particular, the paint adheres to the coating roller 18 of the coating main body 2. In the state, the work can be performed without worrying about the place where the coating main body 2 is placed.

  Next, the transfer separation section 41 holding the paint on the transfer roller 48 is attached to the coating main body section 2 to form the coating roller 1, and while holding the grip section 62, as shown in FIG. On the other hand, coating is performed while rolling the application roller 18 up and down.

  In this case, in the case of the first coating operation, the contact pressure between the coating roller 18 and the transfer roller 48 is adjusted to apply a proper amount to the object to be coated, and the test coating is performed on a plate material for trial coating. The advancing and retreating of the adjusting bolt 15 of the contact pressure adjusting units 13 and 13 is adjusted depending on the situation.

  In addition, even when the transfer roller 48 is worn out and thin during the painting operation, the advance and retreat of the adjusting bolt 15 of the contact pressure adjusting units 13 and 13 are adjusted in order to keep the paint on the object to be coated in an appropriate amount.

  In addition, if the coating roller 1 according to the present embodiment is used, a wide area can be coated by one coating. However, when the coating material to be applied has been reduced, the transfer separation unit 41 is removed from the coating roller 1, The transfer roller 48 is filled with the paint as described above.

  In addition, if there is a place where the work is desired to be performed only by the application roller 18 or only the transfer roller 48 during the coating operation, each of them is separated from the coating roller 1 and used alone.

  As described above, only the convex portion P of the uneven surface can be easily coated over a wide area by the roller having a smooth surface and appropriate hardness as the application roller 18 and the transfer roller 48 capable of holding a large amount of paint. For example, as shown in an outer wall G shown in FIG. 6, a coating is performed using a coating roller 1 using a rubber roller having a smooth surface as the application roller 18 and a wool roller having a bristle length of 8 mm as a transfer roller 48. The target paint C is applied only to the convex portions P without the paint C being attached to S, so that the design having the uneven surface can be clearly shown.

  On the other hand, in the outer wall G shown in FIG. 7 in which the convex portion P is carefully painted with a short hair roller having a bristle length of 2 mm used in the conventional convex painting, the concave portion S and the joint which are part of the design are also coated. C adheres and the design due to the original uneven surface is blurred, which is greatly inferior to the finish by the coating roller 1 according to the present embodiment.

  Further, using a coating roller 1 according to this embodiment using a rubber roller having a smooth surface as the application roller 18 and a wool roller having a bristle length of 8 mm as the transfer roller 48, a flat plate (900 mm A coating area shown in FIG. 8 in which coating was performed on a Lauan veneer material (× 900 mm) and a flat plate (a Rawan veneer material having a size of 900 mm × 900 mm) was applied by a single coating supply using only a rubber roller having a smooth surface. In the coating area shown in FIG. 9, it can be seen that the use of the coating roller 1 according to the present embodiment can hold a large amount of the coating material C, greatly widen the coating range, and can continue the work for a long time.

  As described above, by coating only the convex portion P of the uneven surface using the coating roller 1 according to the present embodiment as described above, the effect of the coating roller 1 described above and the adhesion of the paint C to the unintended concave portion S can be achieved. In addition, it is possible to prevent irregularities and uneven boundary portions from becoming patchy, and it is possible to greatly expand the area that can be painted by one operation.

  As described above, the preferred embodiment of the coating roller 1 and the coating method according to the present embodiment of the present invention has been described, but the present invention is not limited to a specific embodiment, and various modifications and changes are possible. .
