  As described above, conventional materials must be assembled on-site after being thinly rust-prevented and then sprayed. In this case, there is no need for protection because the joints already overlap. However, it is necessary to protect the surrounding buildings, such as windows and pillars, from the coating material, which requires a lot of labor and increases costs. Furthermore, there is a concern that the coating agent may be scattered to nearby buildings and automobiles, which is a cause of pollution. In addition, since spray painting is performed on site, in order to perform spray painting of various patterns, skilled workers must be involved, which is a factor that is inconvenient.

  On the other hand, it is conceivable to provide materials that can be processed by simply cutting them on the site without providing any on-site coating, and providing the material already with aggregate coating. However, the conventional ones that have been applied uniformly with a flat coating or those that have been cut and pasted with a coating agent have been used, but it took a lot of time and increased the cost.

  In order to increase the sense of quality in this material, design changes such as masonry patterns and tiled patterns are required, but in the case of surface coating after embossing to apply design to the material, gold Many molds must be prepared, and metal molds are unsuitable because of high costs, except for mass production.

  The method of painting a building material according to the first aspect of the present invention is to apply a roller wrapped with a design mold with a pattern such as joints on the material to be coated on which the coating agent has been applied in advance before the coating agent is solidified.

  According to a fourteenth aspect of the present invention, there is provided the building material coating apparatus according to any of the ninth to thirteenth aspects, wherein the mounting table comprises a conveyor, and the material and the conveyor are relatively moved.

  Next, the operation will be described. In the coating method and apparatus for building materials according to the first, second and ninth inventions, a jointing pattern or the like is applied to the material to be coated in advance before the coating agent is solidified. When the roller around which the design mold is wound is pressed and rolled onto the material, the unsolidified coating agent is pressed by the design mold and a pattern such as joints is applied to a predetermined thickness. In addition, a thin film is interposed between the design mold and the material so that the design mold and the coating agent do not stick together and break the pattern, thereby improving the peeling after pressing the design mold coating material. The thin film is peeled off from the material surface after the joint pattern is applied.

  In 3rd invention, the surface finishing agent is contained in the thin film, and after the thin film has a joint pattern, the surface of the coating agent is hardened by drying, thereby adding an action of strengthening the outer surface.

  In the fourth invention, a synthetic resin film is used as the thin film, and there is an effect of facilitating peeling from the coating agent.

  In the fifth invention, the length of the design mold having the joint pattern or the like, that is, the diameter of the roller is referred to as the length of the material to be coated, and the joint pattern or the like is prevented from being unnaturally formed.

  In the sixth invention, the depth of the pattern such as joints on the coating agent can be adjusted by adjusting the distance between the material to be coated and the roller. For this reason, it is possible to prevent the coating agent on the joint part from being pushed out and leaving the base or not having a joint pattern.

  In the seventh and fourteenth inventions, since the material to be coated is placed on the conveyor and the roller and the conveyor are relatively moved, the roller smoothly rolls on the material to be coated, Can be applied without shifting the pattern. In this case, the roller may be fixed and the conveyor may be moved, or the material may be fixed and the roller may be moved, and the conveyor may be used only to move the material to another place. Further, the conveyor and the roller can be simultaneously moved in the opposite directions.

  In the eighth and eleventh inventions, a granular material containing aggregate is mixed in the coating agent. In this case, the design pattern such as joint pattern is made of a material having relatively high elasticity. The distance between the roller and the material is adjusted so that the aggregate is buried in the joint.

  In the twelfth invention, since the thin film support is provided for winding the thin film, the thin film is unwound and the coating agent can be spread uniformly in synchronization with the roller rolling on the material. . It is also possible to prepare the support tool before and after the roller so that one side is unwinding the thin film and the other side is peeled off from the surface of the coating agent with joint pattern.

  In the thirteenth invention, the roller is provided with positioning means for setting the relative position to the material, and the joint pattern applied to the material can be made uniform.

  As described above, according to the present invention, a roller on which a design mold such as a joint pattern is separately wound is pressed onto a material to be coated on which a coating agent has been applied in advance before the coating agent is solidified. Since the joint pattern is formed by moving, the joint pattern mold can be easily attached to and detached from the roller, a large number of molds can be prepared at low cost, and the design effect that gives a high-class feeling of the material is exhibited. be able to. In addition, for the pattern of joints and the like, prepare a mold or a large-scale press machine that applies a sheet metal work to the material to be coated in advance as in the prior art, or applies a pattern to the roller itself. It is not necessary and can meet the demands of the market that is cheap and varied.

  Furthermore, according to the present invention, the design mold can be prepared very easily by simply applying a flexible sheet according to the pattern, for example, by cutting it out and winding it around a roller. It is easy to process and detach, and can improve productivity.

  Further, by interposing a thin film with a defect due to adhesion between the design mold and the paint, it can be easily performed without damaging the painted surface, which is economical.

  In addition, the thin film can be provided with a finishing agent and, for example, passed through a heating furnace in a later step, thereby providing weather resistance to the painted surface. Further, since the thin film is made of a synthetic resin, it can be melted or volatilized at the time of post-processing to leave the finishing agent.

  Furthermore, in order to have the continuity of the design type pattern such as joints attached to the roller, the length of the design type is set so as to be aligned with the length of the material to be coated and to be an integral multiple of the length. In response to this, the roller can be easily attached and detached with a different diameter.

  Furthermore, since the roller has means for adjusting the pressing force to the design type coating agent, when using a coating agent containing aggregates, the design should be designed so that the aggregate is embedded in the joint pattern. The pressing force of the mold can be adjusted.

  By placing the material on the conveyor and moving the roller and the material in the opposite directions, the processing location can be saved, the processing time can be shortened, and the efficiency can be improved. it can.

  As in other embodiments, if the roller is arranged in advance after the step of applying the coating agent in advance, the roller is provided with a pattern such as joints at a time over a plurality of materials. The coating agent does not enter the sleeve and the coupling groove, and no mask is required to prevent the paint from adhering to unnecessary parts. Have.

  Embodiments of the present invention will be described below with reference to the drawings. In FIG. 5, reference numeral 1 denotes a material to be used as a building wall material, which is formed by bending a metal plate such as aluminum, iron, or stainless steel plate, and has unevenness on both sides in the longitudinal direction. It has a certain coupling part 2, and the back surface is filled with foamed polyurethane 4 if necessary, and is made by pasting aluminum foil on its outer surface. This is a so-called siding board that is used in combination with the connecting groove 2 of the material 1 in the following order. Further, the material 1 is subjected to appropriate surface treatment on the surface thereof. If necessary, color coating is applied.

  FIG. 1 shows a building material coating method and apparatus according to the present invention. Reference numeral 11 denotes a conveyor on which a material to be coated 1 is placed in a state where a coating agent 12 is applied in advance. Reference numeral 13 denotes a roller on which the design die 14 on the material 1 and having a pattern such as joints is wound. For example, the design die 14 is formed by previously removing a joint pattern from the sheet 15 and bonded to the outer peripheral surface of the roller 13. The joint pattern design die 14 is formed by punching a sheet 15 made of an elastic material such as silicon rubber or foamed urethane, leaving a portion to be the joint pattern 16. If it is not a joint pattern, create a pattern with plaster and pour the material into the mold.

  Thus, the diameter of the roller 13 is determined so that the length of the design die 14 is a fraction of an integer corresponding to the length of the material 1 to be coated. When the design die 14 is wound around the roller 13, the design is processed so that the pattern becomes endless. FIG. 3 is a development view of the design mold.

Further, a synthetic resin thin film 17 is interposed between the roller 13 and the material to be coated 1.
The thin film 17 is wound around a supported support 18 in the vicinity of the roller. When the roller 13 rolls on the material 1, the thin film 17 is unwound from the support 18 and is designed as the design pattern of the roller 13. 14 sticks to the coating material 12 of the material 1 and prevents the pattern such as joints formed on the coating material 12 from being destroyed. This thin film is generally transparent and is not visible in the figure.

  The wound thin film 17 is disposed at a front position in the rolling direction of the roller 13, and is sequentially wound as the roller 13 rolls. When the roller 13 rolls on the material in the opposite direction, the thin film 17 ′ supported by the second support 18 ′ is unwound. The thin film is, for example, a polyolefin film having a thickness of about 40 microns.

  After the roller 13 rolls on the material, it is separated from the material and returned to its original position. The material 1 to which the joint pattern is added slides on the conveyor and is sent to the next process. At this time, the thin film 17 is cut and separated from the material separately.

  Thereafter, the material 1 is coated with a finishing agent and dried, and the coating agent is cured to have weather resistance. When a finishing agent is contained in the thin film, application of the finishing agent can be omitted.

  The roller 13 is provided with positioning means, and the starting position of the design type joint pattern adhered to the roller is aligned with the end 1 ′ of the material. It may be adjusted manually or by an adjustment device.

  The conveyor 11 is provided with fixing means for fixing the conveyor 11 at a position where the conveyor 11 is aligned. The operator places the material 1 on the conveyor 11 and then fixes it with fixing means.

  Further, a pallet (not shown) for placing and fixing the material 1 on the conveyor 11 may be prepared, and the pallet may be moved and the roller 13 may be moved in a direction opposite to the moving direction of the pallet.

  The roller 13 is provided with a pressing spring 19 for pressing the roller 13 against the material 1. However, the weight of the roller 13 may be used.

  The roller 13 can be easily detached from the support 20 and can be replaced with one having a different diameter depending on the length of the material to be coated.

  If necessary, a guide roller (not shown) for unwinding the wrinkle is provided on the support 18 that supports the thin film 17.

  The coating agent 12 may be mixed with a granular material including aggregate. In this case, the degree of pressing of the design mold is adjusted so that the aggregate is embedded in the joint pattern, that is, the depth of pressing of the joint pattern is adjusted to be shallow.

  Further, by selecting a material having solubility for the thin film, it is possible to omit peeling the thin film after pressing the joint mold. A finishing agent that hardens the surface of the coating agent may be mixed into the thin film, and after the joint pattern is added, the finishing agent coating operation may be omitted separately.

  As another example, as shown in Japanese Patent No. 3385339, it has a transport device made of, for example, a conveyor belt transported at a constant speed, and the material 1 is placed on the transport device on the transport device. The coupling grooves 2 are sequentially coupled and placed. Thus, each material 1 is continuously fed into the coating chamber (not shown) by the transport device. In this coating chamber, there is a spray nozzle for coating that is arranged on the transport device and faces the material, and is reciprocated in the longitudinal direction of the material 1, that is, in the direction perpendicular to the moving direction of the transport device. Yes. In this coating chamber, paint is spray-coated from each spray nozzle onto each material placed on the transport device. At this time, the paint is protected so that the paint does not enter the sleeve 3 and the joint groove 2 which are the joint portions of the respective materials 1 by mutual coupling. The coating material sprayed from the inclined nozzle is slightly sprayed around this joint. As the paint sprayed at this time, sand, a granular plastic material, or an aggregate paint including an aggregate corresponding to these is used. This technique is described in detail in Japanese Patent No. 3385339.

  Thus, in the downstream area of the conveyor 7, a roller 13 ′ having the joint mold 14 is pressed on the material 1 ′ on the material 1 that has already been coated with a coating agent. In this case, the roller 13 ′ has an axis in the longitudinal direction of the material 1, and rolls over a plurality of materials. The joint pattern can be rotated once for a plurality of materials.

  If the pattern matches, the spacers are prepared between the materials, and the position can be corrected when the spacers are present, so that the production can be continuously performed. The technical idea such as via the roller 13 ′ or the thin film is in accordance with the above-described embodiment.
