Description

  The present invention relates to a coating device that coats a corner and a chamfered portion of the corner of the corner, and in particular, the corner of the corner that has a chamfered portion that forms an uneven surface along the ridge line of the apex corner. The present invention relates to a protruding corner column in which a chamfered portion is coated, and a coating apparatus for performing the coating.

  In general, as an exterior material used for a projected corner portion of a wall surface of a building, a projected corner pillar A1 as shown in FIG. 11 is known. As shown in FIG. 12a, a ceramic building board 1 having an appropriate surface pattern portion 5 is usually used for manufacturing the protruding corner pillar A1, and it is cut into an appropriate width to produce plate pieces 1a and 1a. Then, one side of each plate piece is cut obliquely (often at an angle of 45 degrees, but not limited to this) (FIG. 12b), and the cut surfaces 2 and 2 are joined together with an adhesive. The shape is substantially L-shaped (FIG. 12c). At that time, the apex portion 3 may be displaced or the adhesive may protrude from the apex portion. For the purpose of removing the apex portion 3, the apex portion 3 may be removed by mechanical means such as a tenoner cutting machine. Is chamfered 4 (FIG. 12d). In the conventional chamfering process, the cutting surface 4 is a wide flat surface having a width of about 10 mm to 20 mm, and the chamfered portion (cutting surface 4) has a color different from the surface of the plate piece 1a. Using an apparatus as described in Patent Documents 1 and 2, post-coating is performed separately.

Japanese Patent No. 3323126 JP 2004-137707 A

  As a surface handle, as shown in a perspective view from above in FIG. 13a and as viewed from the side in FIG. 13b, an emboss made up of a number of ridges 6 and grooves 7 running in a direction intersecting the joint surface The protruding corner pillar A2 may be formed by joining the plate pieces 1a and 1a having a handle. The distance a (FIG. 13b) between the tops of the adjacent ridges 6 and 6 is about 30 mm or less on average, and is often about 5 mm to 20 mm. Moreover, the average depth (distance from the top part of the protruding item | line 6 to the bottom part of the ditch | groove 7) of the ditch | groove 7 is about 10-20 mm, and many things are about 10-15 mm. When daytime light strikes the projected corner pillar A2 having such a surface handle portion, one surface of the ridge 6 formed on the left and right plate pieces 1a, 1a becomes the sunlight portion S, and the other surface is the shadow portion D. This has the advantage of creating a three-dimensional effect.

  Even in the case of the protruding corner column A2 having this shape, it is necessary to chamfer the apex portion 3, and when this is performed by mechanical means such as a tenoner cutting machine, a rhombus is formed as shown in FIG. A chamfered portion 8 w... That is a flat surface is formed for each top of each ridge 6. A coating film can be formed on the chamfered portion 8w with the coating apparatus having the form described in Patent Documents 1 and 2. However, since there is a diamond-shaped chamfered portion 8w that is a flat surface at the top 3, even if appropriate coating is performed, the portion becomes a large sunlight region Sa, and a sense of incongruity is felt.

  Therefore, as shown in FIG. 13, in the projecting column using the plate piece 1a, the chamfering process of the apex corner portion 3 is performed with an air grinder or the like in order to give a natural view to the connecting portion of the left and right plate pieces 1a, 1a. Used and done manually. In this case, as shown in FIG. 1, since the air grinder can be moved along the unevenness formed in the apex portion 3 of the protruding corner column A, a rhombus as described above is formed in the chamfered portion. A flat surface is not formed, and a chamfered portion that follows the irregularities of the apex portion 3 can be obtained. Furthermore, since irregular irregularities of the apex portion 3 can be made to substantially coincide with the numerous ridges 6 and the grooves 7 formed on the surface handle portions of the plate pieces 1a, 1a, the continuity of the joints is also improved. Can be given to those who saw it. The inventors of the present invention have disclosed a protruding corner column having the above-described shape and a manufacturing apparatus capable of performing the manufacturing mechanically rather than manually, as Japanese Patent Application Nos. 2004-159640, 2004-286636, Etc. have already been filed.

  It is desired that the chamfered portion chamfered in this way is applied with the same coating as the surface handle portion, but as described above, there is a recess having a depth of about 10 to 20 mm. In the apparatuses described in Patent Documents 1 and 2, the entire chamfered portion cannot be uniformly coated. For this purpose, painting is performed manually, but it involves a large amount of work.

  Further, even in the case of a building board having an embossed pattern composed of ridges 6 and grooves 7 as described above on the surface of the building board, the processing technique for the surface of the building board and the coating technique therefor have evolved. High pattern value with a variety of patterns and a variety of color patterns by applying different colors to the pattern of the undercoat. Architectural boards are coming to market. Even when a corner column is made using such a high value-added building board, it is not easy to form a pattern similar to the pattern formed on the surface pattern on the chamfered part. It is extremely difficult to form a pattern with a similar color. As a result, it is impossible to give the viewer the continuity of the pattern on the surface pattern of the left and right board pieces, and it has a high commercial value. As a corner pillar, there is still room for improvement.

  The present invention has been made in view of the circumstances as described above, and even when a protruding corner column is made using a plate material in which a pattern with various colors is formed on the surface pattern portion. It is an object of the present invention to provide a protruding corner column in which a chamfered portion is subjected to a coating capable of giving a viewer a feeling that the surface handle portions of the left and right plate members are continuous. Further, there is provided a chamfered portion coating apparatus for a chamfered portion of a projected corner column capable of performing such coating on the chamfered portion of the projected corner column in which a chamfered processed portion forming an uneven surface along the ridge line of the apex corner portion is formed. The purpose is to provide.

  The exit corner column according to the present invention is an exit corner column formed by joining two pieces of plates so that the apex angle portion is formed, and the apex angle portion is along the unevenness of the ridge line of the apex angle portion. A chamfered portion that forms an uneven surface is formed by chamfering, and a coating film by post-coating is formed on the chamfered portion along the uneven surface, and at least one of the coated films is formed. A pattern having a color different from that of the coating film is formed in the region of the part.

  In the protruding corner column according to the present invention, on the coating film formed on the entire surface along the chamfered portion forming the uneven surface formed on the ridge line of the apex corner portion, the color different from that of the coating film is provided. A pattern is formed. Therefore, even when the surface pattern portion of the plate piece constituting the corner of the corner has a multi-color pattern pattern, it is possible to form a corresponding multi-color pattern pattern on the chamfered portion. , The continuity of the left and right surface handle parts can be felt by looking at the projected corner pillar. As a result, the commercial value of the corner is high.

  Further, in the protruding corner column according to the present invention, since the chamfered portion formed so as to follow the irregularities formed on the ridge line of the apex corner portion is coated as described above, the protruding corner column is obliquely oriented. When light is applied to the chamfered portion, it is possible to cause the chamfered portion to have a shadow that is substantially the same as the shadow that occurs on the embossed pattern that forms the surface handle portion. For this reason as well, the chamfered portion is not conspicuous, and it is possible to give a high-class feeling to the corners.

  The chamfered portion is preferably narrow, and the chamfered portion can be made less noticeable. Preferably it is 10 mm or less, More preferably, it is about 8 mm-2 mm, More preferably, it is about 5 mm-2 mm. However, it is not limited to this.

  In the projected corner column according to the present invention, the region where the pattern having a color different from that of the coating film is formed may cover the entire uneven surface of the chamfered portion, or may be only the convex region. In the former case, over the entire surface of the coating film that is the base color painted with a single color formed on the entire surface of the uneven surface (usually, the coating film of the same color as the base color of the surface pattern portion) A pattern with a different color is formed, and in the latter case, the coating film of the base color painted in a single color remains as it is in the concave area of the concave and convex surface, and on the coating film of the basic color in the convex area. Only a pattern with a color different from that of the coating film is formed.

  In the protruding corner column according to the present invention, the pattern formed on the chamfered portion includes at least a part of the pattern pattern included in the surface pattern portion of the plate piece constituting the protruding corner column, or It is a preferable aspect that at least one of the colors of the pattern included in the surface pattern portion of the plate piece to be configured is included. By constructing the handle pattern in this way, those who see the protruding corner pillar can be regarded as a single member with a continuous surface pattern portion with little awareness of the presence of the chamfered portion. The sense of luxury of the pillar is further increased. Of course, when it is desired to make the chamfered portion of the protruding corner stand out consciously, a different pattern and a different color can be adopted.

  Note that, in the exit corner column according to the present invention, it is necessary to form a coating film which is a basic color painted with a single color on the chamfered portion as a pre-process for forming the pattern, and preferably a sealer treatment or In addition, intermediate coating and the like are also performed.

  In the protruding corner column according to the present invention, the size and shape of the uneven surface formed in the chamfered portion are not particularly limited, but the distance between the tops of adjacent convex portions is in the range of 5 mm to 100 mm, and the concave portions are adjacent to each other. It is practical that the depth from the line connecting the apexes between the convex portions is in the range of 2 mm to 20 mm.

  The present invention further discloses a coating apparatus for forming the pattern as described above on the chamfered portion of the protruding corner column. In other words, the chamfered portion coating apparatus for the corner of the projected corner according to the present invention is a device for coating the chamfered portion of the corner of the corner where the chamfered portion that forms an uneven surface along the ridgeline of the apex corner is formed. And a paint reservoir, and a paint supply means for supplying the paint in the paint reservoir to a chamfered portion of the output corner pillar fed by the feed means. The supply means receives a paint supply roll partially immersed in the paint in the paint reservoir, one or more intermediate rolls for receiving the paint carried by the paint supply roll, and the paint carried by the intermediate roll. And an application roll that applies it to the chamfered portion of the protruding corner column, and the intermediate roll in contact with the application roll of the intermediate rolls is a gravure printing roll or a flexographic printing roll, and The diameter of the fabric roll characterized in that it is a size that can enter into the recess in the uneven surface of the chamfered portion.

  In the above-described corner chamfered portion coating apparatus, in coating, the paint in the paint reservoir is conveyed upward in close contact with at least the peripheral surface of the paint supply roll by the rotation of the paint supply roll. The conveyed paint is received (transferred) by the intermediate roll, and then received by the application roll, and then contacted with the chamfered portion of the protruding corner column to which the application roll is sent, thereby chamfering. Part painting progresses. The coating roll is of a size that can enter into the recesses in the concavo-convex surface of the chamfered portion. As the coating roll moves while rotating along the concavo-convex surface, the required pattern is formed on the concavo-convex surface as described later. Is formed.

  In the coating apparatus according to the present invention, the intermediate roll in contact with the coating roll among the one or more intermediate rolls is a gravure printing roll or a flexographic printing roll, and is applied solidly to the paint supply roll (or other intermediate roll). Only a part of the paint is transferred to the gravure printing roll or flexographic printing roll side according to the unevenness (pattern pattern) of the roll surface, which is transferred to the coating roll and to the chamfered portion as described above. Applied. Thereby, the pattern along the roll surface unevenness | corrugation formed in the gravure printing roll which is an intermediate | middle roll, or a flexographic printing roll can be formed in a chamfering process part.

  Forming two or more kinds of pattern patterns by arranging a plurality of paint supply means for supplying the paint in the paint reservoir to the chamfered portion of the outer corner column in series in the feeding direction of the outer corner column, It is also possible to form a pattern with two or more colors, and easily chamfer the pattern pattern on the surface pattern part or the color pattern according to the color formed on the plate piece of the corner It can be applied and formed on the part.

  By appropriately adjusting the amount of paint carried on the peripheral surface of the paint supply roll by providing an adjustment blade or the like, the amount taken (transferred) from the paint supply roll to the application roll side can be set to an appropriate amount. it can. Further, when the intermediate roll is a gravure printing roll, a clearer pattern can be formed by arranging a preparation blade there to eliminate excess paint.

  In the protruding corner column chamfered portion coating apparatus according to the present invention, preferably, the coating material supply means follows the uneven surface formed at the apex corner portion of the protruding corner column fed by the feeding means, and the whole in the vertical direction. To be moved. Thereby, a pattern can be more reliably formed along the uneven surface of the apex portion. As an example of a specific configuration for that purpose, the feed direction of the protruding corner column is set to the horizontal direction, the coating material supply means is disposed below the coating direction, and the entire coating material supply means is urged upward by a spring. A configuration in which the roll is pressed against the chamfered portion of the protruding corner column can be given.

  In the projected corner column chamfered portion coating apparatus according to the present invention, the diameter of the coating roll is basically set to the size of the concave portion on the uneven surface formed in the chamfered portion of the projected corner column to be painted. It will be selected accordingly. In the case of a protruding corner column A formed by joining plate pieces 1a and 1a having an embossed pattern composed of a plurality of ridges 6 and grooves 7 running in a direction intersecting the joining surface as shown in FIG. , That is, the distance between the tops of adjacent ridges is about 5 mm to 20 mm, and the depth of the concave is usually about 2 mm to 15 mm. The range is 10 mm. Also, the diameter of the intermediate roll, which is a gravure printing roll or flexographic printing roll in contact with the application roll, will not be excessive by adjusting the coating amount of the paint supply roll, and the paint supply roll will not contact the convex part of the chamfered part For this reason, about 15 mm to 40 mm is preferable. Although there is no restriction | limiting in particular in the diameter of a coating material supply roll, The thing around 200 mm is desirable. In this case, the diameter of the application roll is approximately 1/100 to 1/20 of the diameter of the paint supply roll, and the diameter of the application roll is sufficiently smaller than the diameter of the paint supply roll.

  There may be one intermediate roll, in which case the intermediate roll is a gravure printing roll or a flexographic printing roll. One or more intermediate rolls having a flat surface may be disposed between the paint supply roll and the intermediate roll which is a gravure printing roll or a flexographic printing roll.

  In the coating apparatus according to the present invention, as described above, the diameter of the application roll is sufficiently smaller than the diameter of the paint supply roll. For this reason, when the concave / convex surface formed on the apex portion has a particularly deep recess, the coating supply roll comes into contact with a nearby convex portion, and the coating roll enters the deep portion of the recess. Things can't happen. It can also be eliminated by interposing an intermediate roll.

  In the projected corner column chamfering portion coating apparatus according to the present invention, the coating roll may have a flat peripheral surface, but grooves may be formed on the peripheral surface by knurling. In terms of material, it is desirable to use a composite of a hard material with a hard core part and a surface that can be easily transferred. For example, it is desirable to use a super hard metal material for the core material and a resin or rubber material for the surface material.

  The material of the intermediate roll may be a metal material, a resin material, a composite material thereof, etc., but a metal material is preferable. The surface of the metal roll may be coated with a resin material. In an intermediate roll which is a gravure printing roll or a flexographic printing roll, a required concave pattern or convex pattern is formed on the surface of the intermediate roll by a conventional method. The paint supply roll may be a normal paint roll, and preferably a rubber roll.

  Furthermore, according to the present invention, by forming a multi-colored pattern pattern on the chamfered portion, the surface corner portion is formed using a plate material having various patterns or various colors, and the corners are made. Even in this case, it is possible to give a viewer a feeling that the surface handle portions of the left and right plate members are continuous. As a result, it is possible to make the corner of the corner more luxurious.

  The present invention will be described below with reference to the drawings. FIG. 1 is an example of a projected corner column according to the present invention, and is a perspective view showing a state before painting a chamfered portion from above, and FIG. 2 is a projected corner column after painting the chamfered portion. It is a schematic diagram for demonstrating. FIG. 3 is a diagram schematically showing a method of applying the coating according to the present invention to the chamfered portion of the protruding corner column, and FIG. 4 is a schematic diagram showing another form of the protruding corner column according to the present invention. FIG. 5 schematically shows an example of a pattern formed on the surface of a gravure printing roll or flexographic printing roll (intermediate roll) used in the present invention. 6-10 is a figure for demonstrating an example of the coating device by this invention.

  FIG. 1 shows a case where the chamfering of the apex corner portion of the protruding corner column made by using the plate pieces 1a and 1a described above based on FIG. A state in which chamfering is performed by an appropriate means along the unevenness formed in the apex portion 3 is shown. In this protruding corner column A, a narrow flat and irregular irregular surface (convex portion 8a and concave portion 8b) corresponding to the repeated pattern of the convex strip 6 and the concave groove 7 of the apex corner portion 3 is formed. A chamfered portion 8s is formed. The chamfered portion 8s is not conspicuous because of its narrow width, and a large sunlight region Sa is not formed as shown in FIG.

  Thus, the coating according to the present invention is applied to the chamfering 8s of the projecting corner column A in which the chamfering 8s that forms the irregular surface along the irregularities of the ridgeline of the apex corner 3 is performed. The protruding corner column A according to the present invention is required to have a chamfered portion having an uneven surface at the apex corner portion, but the surface handle portions of the left and right plate pieces 1a, 1a and the handle pattern thereof are arbitrary. 1 is merely one example.

  In the projected corner column A shown in the schematic diagram of FIG. 2, a coating film P which is a basic color is formed on the entire surface of the left and right plate pieces 1a, 1a. One pattern Pa is formed with a color Ca different from the base color, and a second pattern Pb indicated by a circle is also formed with a color Cb different from the base color. The chamfered portion 8s formed in the apex portion 3 has an uneven surface, but the unevenness is omitted in FIG.

  In this example, the chamfered portion 8s has a coating color P as a base color formed on the entire surface, as with the surface of the plate piece 1a. Has also been done. On the coating film P, a pattern pattern Pa1 similar to the first pattern pattern Pa is formed with the color Ca, and a pattern pattern Pb1 similar to the second pattern pattern Pb is also formed with the color Cb. .

  Since the chamfered portion 8s of the protruding corner column A is coated as described above, the viewer can see the pattern of the surface handle portion formed on the left and right plate pieces 1a, 1a. You can feel as if it is continuous in 8s. Furthermore, in this example, as shown in FIG. 1, the chamfered portion 8 s has a narrow width and is a concavo-convex surface corresponding to the concavo-convex pattern formed on the surface handle portion. It can be felt as if it is continuous with the shadows generated on the left and right plate members 1a, 1a, and it becomes a corner with a sense of quality without any discomfort.

  Such coating can be performed using a coating apparatus as shown in FIG. In FIG. 3, reference numeral 36 denotes a paint supply roll immersed in the paint Cb in the paint reservoir not shown in FIG. 3, and the paint Cb is pulled up along the roll surface by the rotation of the paint supply roll 36. The paint supply roll 36 is in contact with a gravure printing roll 50 as an intermediate roll, and the raised paint Cb is formed on the roll surface of the gravure printing roll 50 and a number of recesses 51 formed in a specific pattern on the surface. Received within. The adjusting blade 60 abuts against the roll surface of the gravure printing roll 50, and the paint Cb adhering to the roll surface is dropped during the rotation, and only the paint Cb in the recess 51 is further carried. The application roll 40 is in contact with the gravure printing roll 50, and the paint Cb in the numerous recesses 51 forming the specific pattern Pb1 is transferred to the surface of the application roll 40 with the pattern Pb1 remaining.

  On the other hand, the protruding corner column A is transferred in the arrow direction with the chamfered portion 8s facing downward. The coating material supply means including the coating roll 40 is entirely along the concavo-convex surface of the chamfered portion 8s while maintaining the state where the coating roll 40 is in contact with the concavo-convex surface of the chamfered portion 8s of the protruding corner column A to be transferred. So that it can move up and down. The application roll 40 can be rotated in synchronization with the transfer.

  Therefore, the coating material Cb transferred to the coating roll 40 with the pattern Pb1 formed on the gravure printing roll 50 maintains the same pattern, and the upper surface of the uneven surface formed on the chamfered surface 8s of the protruding corner material A. Is transcribed.

  In the example shown in FIG. 3, the chamfered surface 8s of the protruding corner column A has already been coated with the coating film P, which is the basic color of the surface pattern portion of the plate piece 1a, and the coating of the same form. The pattern pattern Pa1 similar to the first pattern pattern Pa formed on the surface pattern portion of the plate piece 1a is applied on the coating film P with the color Ca using the apparatus (in FIG. 3). The black circle indicates the pattern Pa1). On the surface of the gravure printing roll 50, a pattern pattern Pb1 similar to the second pattern pattern Pb formed on the surface pattern portion of the plate piece 1a is formed as a pattern. Used. Therefore, when the protruding corner column A passes through the coating roll 40, a pattern Pb1 that is a color Cb is further added to the surface of the chamfered portion 8s (Note that in FIG. 3, the pattern Pb1 is a white circle. Is shown). The protruding corner post A after being painted in this way is shown as a schematic diagram in FIG.

  Although not shown, when a flexographic printing roll is used instead of the gravure printing roll 50, the coating material of the coating material supply roll 36 is transferred to the convex portion of the flexographic printing roll, and is output via the coating roll 40. By being applied to the chamfered portion 8s of the corner pillar A, a pattern is formed on the chamfered portion 8s in the same manner as in the case of the gravure printing roll 50. In this case, it is recommended that a coating thickness adjusting blade be attached to the peripheral surface of the paint supply roll 36 so that an appropriate amount of paint is transferred from the paint supply roll 36 to the convex portion of the flexographic printing roll.

  In the projected corner pillar A shown in the schematic diagram of FIG. 4, the pattern patterns Pa1 and Pb1 are formed only in the convex region 8a of the chamfered portion 8s, and are not formed near the bottom surface of the concave portion 8b. Thus, if the vicinity of the bottom of the concave portion 8b is left in the basic color, the viewer can feel the depth by the convex portion. By controlling the amount of vertical movement of the application roll 40 as shown in FIG. 4 (that is, the application roll 40 does not reach the bottom of the recess 8b of the chamfered portion 8s), Can be manufactured.

  In the above description, the pattern patterns Pa1 and Pb1 that match or substantially match the pattern and color formed on the plate pieces 1a and 1a are formed on the chamfered portion 8s. A color pattern may be formed. For example, as shown in FIGS. 5a to 5e, a horizontal line pattern (FIG. 5a), a spherical pattern (FIG. 5b), a vertical line pattern (FIG. 5c), a wavy line pattern (FIG. 5d), and an abstract pattern combining them (FIG. 5e) It may be. Different color paints may be selected for the same pattern.

  Next, a specific example of a coating apparatus for coating the chamfered portion 8s of the protruding corner column A as described above will be described with reference to FIGS. FIG. 6 is a front view showing an embodiment of a chamfered portion coating apparatus for a corner projection according to the present invention, and FIG. 7 is a right side view thereof. FIG. 8 is an enlarged perspective view of a main part of the coating apparatus, partially broken away, FIG. 9 is a front view thereof, and FIG. 10 is a right side view thereof.

  The apparatus 10 has a machine casing 11, and a universal wheel 12 and an adjustment bolt 13 that functions as a stand are attached to the lower end surface of the machine casing 11. At the center of the machine frame 11 in the up-down direction, a feeding means 20 for a protruding corner column is attached. The protruding corner column feeding means 20 includes a supporting roll 21 that supports the protruding corner column A that is transferred with the chamfered apex portion 3 as a lower side, and a frictional force that contacts the protruding corner column A from the upper surface. Are provided with a feed roll 24 that feeds the protruding corner post A and a drive motor 28 for the feed roll 24.

  The support roll 21 is composed of left and right support roll groups arranged so as to be in contact with the left and right plate pieces 1a and 1a of the left and right plate pieces 1a and 1a of the outgoing corner post A, and in the illustrated example, the surface of the metal roll The two groups of support rolls 21 with the urethane sheet attached to each other form an angle of 90 degrees with respect to the fixed frames 22 and 22 fixed to the machine frame 11 and the support shafts 23 and 23 are It is mounted in a freely rotatable manner. It should be noted that in the part where the paint supply means 30 described later is disposed, the fixed frames 22 and 22 are partially cut away so that the paint supply means 30 can paint the chamfered portion 8s of the protruding corner column A. Has been.

  The feed roll 24 comes into contact with the protruding corner pillar A in a posture in which the surface handle portion side is supported by the support roll 21 from above, and in this example, as shown in FIG. The rolls 24 and 24 form one pair, and the respective conical surfaces 25 and 25 are in contact with the back surfaces of the left and right plate pieces 1a and 1a, respectively. The feed roll 24 is also preferably provided with a urethane coating on the surface.

  A plurality of pairs of feed rolls are attached to a moving support frame 26 that is mounted so as to be movable up and down with respect to the machine frame 11 (FIG. 6). When the roll 24 comes into contact with the protruding corner pillar A and the movable support frame 26 rises, each feed roll 24 also rises, and a wide work space is secured below the feed roll 24. A drive motor 28 is attached to the machine frame 11, and the rotational force of the drive motor 28 is transmitted to each feed roll 24 through a transmission system 29 such as a chain or a belt.

  The handle 27 is operated to move the moving support frame 26 and the feed roll 24 upward, and the formed open space is used on the support roll 21 on the upstream side in the feed direction, for example, as shown in FIG. The chamfering process is performed along the unevenness of the apex corner portion 3 by an appropriate means, and the chamfering processing portion 8s below the protruding corner column A in which the chamfering processing portion 8s having the uneven surface is formed on the apex corner portion 3 Place it side by side. Next, the handle 27 is operated to move the moving support frame 26 and the feed roll 24 downward so that the feed roll 24 is in contact with the back surfaces of the plate pieces 1a and 1a of the protruding corner pillar A. When the drive motor 28 is driven in this state, the rotational force is transmitted to each feed roll 24 via a transmission system 29 such as a chain, and the protruding corner column A is sent on the support roll 21 to the downstream side.

  The coating material supply means 30 is located below the fixed frame 22 that rotatably supports the support roll 21 described above. In the illustrated example, the two coating material supply means 30 having the same structure are attached in the feed direction of the protruding corner pillar A, but may be one, or may be three or more. The paint supply means 30 includes a frame 32 whose one end portion is supported so as to be swingable about the support shaft 31 with respect to the machine frame 11. The frame 32 is preferably made of a steel plate. The frame 32 extends parallel to the feed direction of the protruding corner pillar A, and the support shaft 31 is orthogonal to the feed direction. The frame 32 is supported at a point 33 (FIG. 9) upstream of the support portion by the support shaft 31 so as to be pulled downward by the spring 34, and as a result, the support shaft of the frame 32. A portion on the downstream side in the feed direction with respect to the support portion 31 is urged upward. The biasing force by the spring 34 can be made variable by an appropriate means (not shown).

Rotating shafts 39 and 55 are supported. A gravure printing roll 50 as an intermediate roll described with reference to FIG. 3 is attached to the tip of the lower rotating shaft 55 so as to contact the peripheral surface of the coating material supply roll 36. A coating roll 40 is attached so as to be in contact with the peripheral surface of the printing roll 50. The diameter of the gravure printing roll 50 is about 15 mm to about 30 mm, and the diameter of the coating roll 40 depends on the shape of the chamfered portion 8s of the projected corner pillar A to be painted, but is about 2 mm to about 10 mm. It is.

  The machine casing 11 is provided with a second drive motor 42, and the rotation of the second drive motor 42 is transmitted via a pulley 43 and a belt 44 to a pulley 45 attached to the rotation shaft 35 of the paint supply roll 36. . Further, the machine casing 11 is provided with a paint tank 48 opened upward as a paint reservoir, and a part of the paint supply roll 36 always enters the paint 49 stored in the paint tank 48. Further, in FIG. 9, reference numeral 61 denotes an adjustment blade so as to face the peripheral surface of the paint supply roll 36, so that a gap (distance) with the peripheral surface of the paint supply roll 36 can be changed by a mechanism (not shown). And attached to the machine casing 11. Reference numeral 60 denotes a blade in contact with the gravure printing roll 50 described with reference to FIG.

  As described above, the chamfered portion 8s formed in the apex portion 3 reaches the position of the coating roll 40 as the protruding corner column A is fed by the driving force of the feeding roll 24. The coating roll 40 is maintained in a state of being urged upward by the spring 34 together with the frame 32, and when the protruding corner column A is further fed, the coating roll 40 is moved together with the frame 32 of the protruding corner column A. The chamfered portion 8s can move in the vertical direction along the unevenness. As described above, the diameter of the coating roll 40 is set to a size that can enter the concave portion 8b in the concave and convex portions of the chamfered portion 8s. It is sent out to the downstream side in a state where it always contacts. Meanwhile, the application roll 40 is in contact with the peripheral surface of the gravure printing roll 50 as described with reference to FIG. 3, and the gravure printing roll 50 is in contact with the peripheral surface of the paint supply roll 36, The application roll 40 and the gravure printing roll 50 rotate synchronously by frictional contact.

  At the time of painting, an appropriate paint 49 (color Cb paint according to the example of FIG. 3) is put in the paint tank 48, and the second drive motor 42 is driven. As a result, the coating material supply roll 36 rotates, and the coating material 49 is conveyed upward while being in close contact with at least the peripheral surface of the coating material supply roller 36. Thereafter, the paint 49 of the color Cb is transferred to the chamfered portion 8s of the protruding corner post A through the gravure printing roll 50 and the coating roll 40, and the pattern Pb1 is formed as described above.

  In an apparatus in which two paint supply means 30 are arranged as in the apparatus 10 shown in FIGS. 6 and 7, different paints 49 (in the example of FIG. 3, the paint of color Ca and the color Cb in each paint tank 48). And a different pattern (in the example of FIG. 3, pattern patterns Pa1 and Pb1) are formed on the peripheral surface of each gravure printing roll 50 in one feed. Two pattern patterns can be formed on the virtual coating film P. Further, in order to form the coating color P which is the basic color on the chamfered portion 8s, the gravure printing roll 50 is removed from the apparatus 10 shown in FIGS. 6 and 7 so that the paint supply roll 36 and the coating roll 40 are in direct contact with each other. Alternatively, painting may be performed by replacing the gravure printing roll 50 with an intermediate roll having a flat surface.
