Description

[0001]
[Industrial application fields]
The present invention is a so-called interior / exterior panel (hereinafter simply referred to as a material) that is advantageous for forming a lateral wall and a longitudinal wall of an interior / exterior of a building structure. In particular, the present invention relates to a method and apparatus for coating the material.
[0002]
[Prior art]
As this kind of material used conventionally, there is one described in Japanese Patent Publication No. 5-58106. In general, these materials are made by bending aluminum, iron, and stainless steel, and in some cases, a heat insulating material such as foamed polyurethane is attached to the back surface, and the surface of a core material such as gypsum board is preliminarily provided. Some of them have a decorative finish. There are joints at both ends in the longitudinal direction of this material, for example, a sleeve is provided on one side and a joint groove is provided on the other side. Used as a wall material for houses.
However, in the conventional product, the surface of the material is subjected to a relatively thin coating, and a favorite material is selected and used depending on the color scheme of the coating agent (paint). Depending on the case, what provided the unevenness | corrugation by the sheet metal process on the surface of the raw material is also provided. In addition, as described above, there are those that are particularly surface-treated. Thus, these materials are used by being laminated on a wall surface of a house or the like while appropriately cutting the materials at a construction site.
By the way, recently, the diversification of buildings has progressed, and the design features of the wall surface have been demanded, and the material is also painted with aggregate (sand or granular material is mixed in the coating agent to create a three-dimensional feel, high-class It has been demanded that it has a feeling and represents a unique surface. If this material is applied to the entire surface of the material, the joint between the materials will not fit properly, causing rainwater to enter. In order not to do so, protective measures must be taken before applying the aggregate paint. Or, after finishing the assembly of materials at a construction site, there is a case where aggregate coating is performed.
[0003]
[Problems to be solved by the invention]
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 which the materials are bonded together from the coating agent, 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 at the site, skilled sprayers must be involved in order to perform uniform spray coating, which is a factor in inconvenience.
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. In this case, the disadvantages associated with the painting performed at the site described above can be eliminated, but at the time of painting the material, it is necessary to take measures to protect the application of the aggregate paint at the joint portion of each material. It is inefficient because it is inefficient because tape is attached to the sleeve and the groove of the material that is the joint, and then the aggregate coating is painted one by one and dried, and then the protective tape is peeled off. In addition, the tape to which the paint is attached has to be processed, and if it is simply incinerated, it becomes air pollution and causes pollution.
Furthermore, when applying various designs and patterns when painting materials, when using a single color coating agent, it is necessary to prepare a large number of various coating agents, and the inventory management becomes complicated, It causes high costs. In addition, in order to carry out various kinds of small-scale production, it is necessary to change the coating agent every time the color or pattern is changed, and labor and material loss occur, and the work is complicated and complicated.

[Action]
In the building material coating apparatus and method according to the present invention, each material is pre-coupled to the conveying device in order to provide inexpensively a building material with a decorative coating that is thickly applied to the surface except for the joint portion of the material. In this state, it is continuously supplied, painted toward an integrated material, and uniformly applied to the whole. Since different types of paints having different colors, for example, are sprayed from the nozzle group at the same time, a predetermined pattern is applied while blending colors or changing patterns or patterns. After drying, the bonds are released again, and the materials are separated and shipped for delivery. Therefore, at the construction site, the materials are simply combined and used, and it is not necessary to separately spray the material surface. In addition, when the material is produced, there is no need to attach a protective tape or the like for protecting the joint portion of each material from the coating agent, and the efficiency is improved.
Moreover, in the building material coating apparatus and method according to the present invention, it is possible to apply a pattern or pattern applied to the material with a predetermined pattern. In addition, since a plurality of nozzles are prepared, and these are simultaneously supplied with paints of different colors with respect to the moving direction, the applied color can be uniformly applied according to a predetermined one. By changing the amount of paint supplied to each nozzle, the pattern (pattern) to be applied can be changed, and the inconvenience of having to extract all the paint for changing the design can be eliminated. Since the nozzle group reciprocates in the longitudinal direction of the material, the paint is applied with a certain thickness and pattern in combination with the moving speed of the material conveying device, so that a certain quality can be maintained. Also, it does not occur uneven coating compared to the hand-painted. Furthermore, since it is applied against the upper surface of the material from above the conveying device, aggregate coating with relatively weight, compared with the case of coated material Te standing, no sag of the paint.
In the case where granular materials including aggregates are mixed in the coating agent , the surface of the material can be expressed rough, and it has the effect of making the house look gorgeous. Since there is no such aggregate, the material can be easily attached to a house or the like.
In the building material coating apparatus and method according to the present invention, when placed on the conveying device, the joint on the one side in the longitudinal direction of the material is left coupled to the sleeve on the other side of the next material, Since it is continuously supplied and separated after painting, it is convenient for handling at the construction site because there is no thick coating on the joint. In addition, since it is continuously supplied, the paint surface is wide, and even if the paint scatters, it adheres to the material again, so that the waste of the paint as a whole is small.
After the coating containing the aggregate is applied, the bonding of each material is released and the finishing agent is applied, so that the aggregate paint can be made strong and can withstand environmental changes.
In addition, a variable adjustment device is provided for the control device of the transport device drive device, nozzle support device drive mechanism, and paint supply mechanism (pump) to each nozzle. The design or color can be adjusted.

【Example】
Embodiments of the present invention will be described below with reference to the drawings. 3 and 4, 1 is a material used as a building wall material, for example, formed by bending a metal plate such as aluminum, iron, stainless steel plate, etc., and bonded to one side in the longitudinal direction The groove 2 has a sleeve 3 on the other side, the back surface is filled with foamed polyurethane 4 if necessary, and the outer surface is made by applying an aluminum foil 5 to make up the material. This is a so-called siding board in which 1 is fitted to the sleeve 3 and the coupling groove 22 of another material 11 and is coupled in the following order. The surface of the material 1 is subjected to appropriate surface treatment.
Further, the material 1 may be non-metallic, for example, a plaster plate that has been surface-treated, and is provided with a coupling groove 2 and a sleeve 3. The surface is colored if necessary. An uneven pattern (not shown) is provided on the surface of the material.
FIG. 1 shows a building material coating method and apparatus according to the present invention, which has a transport device 7 made of, for example, a conveyor belt or a chain transported at a constant speed. 11 is mounted by sequentially coupling its sleeve 3 and the coupling groove 2. Thus, the raw materials 1 and 11 are continuously fed into the coating chamber 20 by the transport device 7. The coating chamber 20 includes a coating nozzle group 21 disposed on the transport device 7 and facing the material. The nozzle group 21 includes a plurality of nozzles and is supported by the nozzle support 8. . The nozzle support 8 is reciprocated at a predetermined speed by the moving mechanism 31 in a direction perpendicular to the moving direction of the material on the conveying device 7 in synchronization with the moving speed of the conveying device. Reference numerals 221, 222, 223, and 224 denote pumps that are coating agent supply mechanisms for feeding paint to the nozzles 211, 212, 213, and 214. 231, 232, 233 and 234 are conduits made of a flexible material for transporting paint.
Reference numeral 25 denotes a transport device drive mechanism. A variable adjustment device 28 is provided in the control device 27 that controls the transport driving mechanism 25, the nozzle support moving mechanism 26, and the coating agent supply mechanisms 221, 222, 223, and 224.
FIG. 5 shows an arrangement state for attaching each nozzle 211, 212, 213, 214 to the nozzle support 8, for example, two in the moving direction of the nozzle support 8 and two in the moving direction of the transport device Are provided vertically and horizontally. The coating agent is supplied to the nozzle in the same color on a diagonal line.
In the coating chamber 20, paints are sprayed and applied from the nozzles 211, 212, 213, and 214 to the materials continuously placed on the transport device 7. 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 materials 1 and 11 by mutual coupling. Furthermore, the entire surface is evenly applied to the uneven pattern on the surface of the material 1. As the paint sprayed at this time, sand, a granular plastic material, or an aggregate paint including an aggregate corresponding to these is used.
Thus, the supply of the coating agent (paint) to each nozzle supplies paints of different colors to adjacent nozzles in the moving direction of the nozzle support. For example, the nozzle 211 is white and the nozzle 212 is gray. The color adjustment is performed by adjusting the discharge amount of the paint supplied to the nozzle and the compressed air amount for ejecting the paint. Furthermore, the pattern (pattern) to be applied can be changed by the transport speed of the transport device and the driving speed of the nozzle support mechanism.
In addition, the paint sprayed from the nozzles 211, 212, 213, and 214 located above the material 1 is arranged on the material even if the viscosity is weakened. The production speed can be increased without flowing.
Next, the materials 1 and 11 conveyed from the coating chamber 20 are transferred to the drying chamber 23, and the surfaces of the materials 1 and 11 are dried by hot air to cure the paint. The raw materials 1 and 11 conveyed and sent out from the drying chamber 23 are separated from each other, and are then finished and delivered to the market. This finish paint protects the aggregate paint and more closely adheres to the material.
In the building material coating method and apparatus of the present invention, in the drying process in the drying chamber, the temperature of the drying air is compared in order to protect the heat insulating material such as foamed polyurethane focused on the back surface of the materials 1 and 11 from high temperatures. It is set to a low value to increase the air volume and shorten the drying time. Reference numeral 24 denotes a blower fan. The heat source is not shown.
FIG. 2 shows a process diagram of the building material coating method and apparatus according to the present invention. In the first process, the raw materials 1 and 11 are transported separately, and undercoating is applied. This is performed to increase the adhesion between the paint and the fabric in the next step. In the second step, the undercoat is dried. In some cases, the first and second steps may be omitted. That is when the material is already primed or when the material is non-metallic.
Subsequently, in the third step, each material is joined at the joint and the aggregate coating is performed, and the material in the painting chamber is placed on the transport device in advance so that it is in a state of one piece as a whole. Then transported towards the painting room. Although it is painted in the painting room, as described above, since the connecting portions are overlapped, the entire material is uniformly coated without being subjected to the aggregate coating. The color of this aggregate is adjusted by the amount of paint discharged from each nozzle and the amount of compressed air, and the pattern is adjusted by adjusting the moving speed of the nozzle support and the conveying speed of the conveying device. The adjustment of the color and pattern is performed in advance by the variable adjustment device of the control device to be described above, and what color or pattern (pattern) is to be managed to what extent.
The fourth step is an aggregate coating drying step, which takes a longer time than in the previous second step and is dried. After this fourth step, the material is separated from the joint portion, and the top coat is finished again in the fifth step. This finish paint increases the weather resistance and stain resistance, and prevents the peeling of the aggregate. In the sixth step, drying is performed to cure the finish. Each material is shipped after being dried. In the first step, several types of paints are switched in the first step, and in the third step, several types of aggregates are switched. In the fifth step, a specific finishing agent is used. Is done.

[Other embodiments]
FIG. 6 shows another embodiment of the present invention, which is effective when the transport device 7 cannot be made very wide with respect to the material. That is, this is a case where the materials 1 and 11 are arranged in the longitudinal direction in accordance with the moving direction of the conveying device 7, and several materials are arranged in a combined state in the width direction of the conveying device. By continuously flowing the set of combined materials, the respective materials can prevent the paint from hitting their respective joint portions, thereby achieving the initial purpose. However, in this case, for the material located at the end of the conveying device, it is necessary to treat the portion 3 of the sleeve or the coupling groove 2. In this respect, even if it has a defect with respect to the previous embodiment, it is possible to exert a sufficient effect as compared with the case where each material is covered with the bonded portion. This clothing treatment is performed by providing a fixed cover (not shown) to prevent the paint from penetrating into the non-painted part in the painting chamber, or by coating the sleeve or the coupling groove of the material located at the end. However, measures such as peeling off afterwards must be taken.

【The invention's effect】
As described above, according to the present invention, in order to continuously transfer the material to be coated, the overlap of each material is placed on the conveying device in a state of being polymerized, and is coated toward the material being conveyed. The nozzle group for ejecting the agent reciprocates in a direction different from the conveying direction of the conveying device and simultaneously supplies different types of coating agent to each nozzle. In this state, a thick coating such as an aggregate paint can be applied, and the installer does not need to perform on-site coating simply by cutting the painted material. In addition, since the coating is continuously performed on a flat surface, there is no waste of dripping, and high quality is maintained. Furthermore, since different paints are supplied to each nozzle at the same time, it is easy to adjust colors and patterns for various designs, and the number of paint types can be managed to improve productivity and reduce costs.
In addition, since the nozzle group is supported by a nozzle support that reciprocates at a predetermined speed in synchronization with the transport speed of the transport device, the amount of paint supplied to the material is stably and evenly distributed over the material. High quality and high efficiency can be maintained.
[0021]
Each nozzle is arranged horizontally and vertically on the nozzle support so that different color paints are ejected from adjacent nozzles in the moving direction of the nozzle support so that the surface of each material is uniformly and stably coated. It is possible to prevent the occurrence of uneven coating and insufficiently coated portions. It is also easy to apply aggregate paint to the desired thickness by changing the amount of paint discharged from the nozzle and the amount of jet air, or changing the moving speed of the nozzle support and the conveying speed of the conveying device. Become. Furthermore, by switching the coating material supplied from the nozzle, it is possible to respond quickly to market demands, which has a great industrial effect.
In Rukoto using a so-called aggregate coating impregnated with bone material coating, on which can be represented more design effect to the surface irregularities of the material, in order to appropriately adjust the type and amount of aggregate It is possible to respond easily according to the transfer speed of the transfer device, the moving speed of the nozzle, the discharge amount of the paint or the discharge amount of these and the compressed air, and supply stable quality materials in large quantities in a short time. I can do it.
Or, by supplying aggregate and paint to the material to be coated with separate nozzles, clogging of the nozzles can be alleviated, and the supply amount of paint and aggregate supplied from each nozzle It is possible to perform efficient painting by adjusting the amount.
In particular , according to the present invention , each material is directed to the nozzle group in a state in which a sleeve provided on the other side of the second material is preliminarily superposed on a joint provided on one side in the longitudinal direction of the first material. Since the paint is not allowed to enter the polymerized part of each material, it is easy to assemble at the construction site and a sufficiently thick pattern can be applied at the time of painting. The design effect is great. Furthermore, since the coating area of the material is large, the coating material to be applied is not wasted and can be finished economically.
After applying the aggregate paint , after uncoupling the materials, finish painting each material not only prevents the aggregate paint from peeling off, but also increases the gloss of the material, In order to perform this finish coating, it is possible to reduce the viscosity of the aggregate paint at the time of aggregate coating, and contribute to the improvement of production efficiency by increasing the flowability in the conduit and nozzle of the paint I can do it.
