Description

  The present invention relates to a method for manufacturing a building panel having a surface design.

  Conventionally, surface designs have been formed on the surface of building panels used for building exterior materials and interior materials by applying irregularities or painting to improve the appearance of the building. Yes. For example, Patent Document 1 discloses an architectural panel in which a predetermined uneven shape is applied to the surface and then painted using a coating roll having a coating pattern corresponding to the uneven shape on the peripheral surface.

  By the way, in recent years, there has been a tendency to favor the appearance of buildings with a natural appearance by eliminating artificial regularity as much as possible. In addition, the applicant of the present invention, for example, cuts a long panel having a certain uneven pattern on the surface repeatedly in the longitudinal direction at an arbitrary position in the longitudinal direction to form a large number of architectural panels. I thought about forming walls and so on. In other words, the large number of architectural panels formed in this way are each formed into a concavo-convex shape in which the concavo-convex pattern is shifted in a direction extending between a pair of cut end faces by being cut at an arbitrary position in the longitudinal direction of the long panel. Therefore, although the uneven pattern has in common, each building panel has a different surface design, and if such a large number of building panels are arbitrarily arranged to form a wall, etc., each building panel It is possible to obtain the appearance of an irregular natural building by arbitrarily arranging different surface designs.

However, in order to paint these architectural panels according to their concavo-convex shape, the concavo-convex shape of each building panel is different, so a coating pattern tailored to each concavo-convex shape must be prepared for each building panel. The productivity is remarkably bad. By the way, since each uneven | corrugated shape of these building panels has an uneven | corrugated pattern in common, in order to improve productivity, it uses the coating roll which has the coating pattern corresponding to the uneven | corrugated pattern with reference to patent document 1. It is conceivable to paint the surface of each building panel, but each building panel is cut at an arbitrary position in the longitudinal direction of the long panel, and each concavo-convex shape has a concavo-convex pattern between a pair of cut end faces. Since it is formed so as to deviate in the direction, it is difficult to align the coating roll to match the coating pattern to the uneven shape peculiar to each building panel, and therefore it has a coating pattern corresponding to the uneven pattern The current situation is that it has not been realized to paint architectural panels with different uneven shapes with good productivity by means of painting.
JP-A-6-278355

  The present invention has been made in view of the above-described conventional problems, and corresponds to the above-described uneven pattern for each building panel cut at an arbitrary position in the longitudinal direction of the long panel subjected to the uneven pattern. It is an object of the present invention to provide a method for manufacturing a building panel that uses a painting means for painting with a painting pattern and enables painting with high productivity.

In order to solve the above-mentioned problem, the method for manufacturing a building panel according to claim 1 of the present invention repeatedly applies a certain concavo-convex pattern 3 on the surface of the long panel 2 in the longitudinal direction by a press. Is cut at an arbitrary position in the longitudinal direction, and a reference mark 4 having a predetermined positional relationship with the concavo-convex pattern 3 is applied with a through-hole penetrating in the thickness direction to form a building panel 1. 5 is conveyed toward the traveling direction, the detection means 9 is disposed above the position where the reference mark 4 passes , and the coating means 7 is provided so as to apply the coating pattern 6 corresponding to the uneven pattern 3. Before the building panel 1 is carried into the coating apparatus 8, the cutting end surface 5 and the reference mark 4 on the transport front end side of the building panel 1 are detected by the detection means 9, and the distance between the cutting end surface 5 and the reference mark 4 is calculated. In addition, the position of the cut end surface 5 in the concavo-convex pattern 3 is specified based on the calculated distance between the cut end surface 5 and the reference mark 4 and the positional relationship between the reference mark 4 and the concavo-convex pattern 3, and the specified concavo-convex Based on the position data of the cut end face 5 in the pattern 3, the painting start position 6 a in the painting pattern 6 of the painting means 7 is set, and the painting means 7 applies the above coating to the surface of the building panel 1 carried into the painting device 8. The painting pattern 6 from the start position 6a is painted.

  According to this, in the building panel 1 formed by cutting at an arbitrary position in the longitudinal direction of the long panel 2 to which the concave / convex pattern 3 is applied, the concave / convex pattern 3 is formed in a direction extending between the pair of cut end faces 5. Each building panel 1 has a different uneven shape, but the reference mark 4 having a predetermined positional relationship with the uneven pattern 3 is applied to the building panel 1, and the uneven pattern 3 is based on the reference mark 4. The position of the cut end face 5 is specified, the position of the cut end face 5 in the paint pattern 6 corresponding to the uneven pattern 3 of the paint means 7 is specified, and the paint start position 6a in the paint pattern 6 is set. By applying the coating pattern 6 from the start position 6a, it is possible to perform painting that matches the uneven shape of the building panel 1, that is, the coating pattern corresponding to the uneven pattern 3 By coating means 7 for painted down 6 in which it was possible to perform good productivity painted to match the uneven shape of the building panel 1.

  A building panel manufacturing method according to claim 2 is the method of manufacturing a building panel according to claim 1, wherein the painted surface of the paint pattern 6 corresponding to the concave / convex pattern 3 is formed on the peripheral surface, and the paint surface is rotated by a drive motor. The coating means 10 is configured by the coating roll 10 that is applied by being pressed against the surface of the building panel 1, and the cut end surface 5 a on the transport front side of the transported building panel 1 reaches the coating position 24 of the coating roll 10. The rotation of the drive motor of the coating roll 10 is decelerated or accelerated so that the coating start position 6a in the coating pattern 6 of the coating roll 10 is positioned in accordance with the timing, and the building panel 1 carried into the coating apparatus 8 is controlled. The coating pattern 6 from the coating start position 6a is applied to the surface by the coating roll 10. According to this, since the coating start position 6a of the coating pattern 6 can be positioned on the cut end face 5 of each building panel 1 by the rotation control for decelerating or accelerating the drive motor of the coating roll 10, the coating means 7 is applied as a coating means. Since the simple configuration of the roll 10 can be adopted and the building panel 1 can be transported at a constant speed even in the painting process, the productivity of the building panel 1 can be improved.

  Moreover, the manufacturing method of the building panel which concerns on Claim 3 WHEREIN: The convex male fruit 12 fitted so that it may be covered with the concave female fruit 11 provided in the adjacent architectural panel 1 in Claim 1 or 2 is provided. The building panel 1 is formed so as to be sandwiched between a pair of cut end surfaces 5 and a reference mark 4 is provided on the male fruit 12. According to this, at the time of use (at the time of construction to a building) of the building panel 1 in which the adjacent building panels 1 are connected by fitting the male fruit 12 and the female fruit 11, the standard applied to the male fruit 12. The mark 4 is covered with the female fruit 11 so as not to appear in the appearance of the building, and deterioration of the appearance of the building due to the reference mark 4 can be avoided.

  The present invention has an advantage that coating can be performed with high productivity in accordance with the uneven shape which is different for each building panel by the coating means which performs painting with a coating pattern corresponding to the uneven pattern.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  The building panel 1 of this example is a ceramic-based (cement-based) or metal-based building panel 1 used for building exterior materials, bathroom inner walls, interior materials, etc., and is extruded as shown in FIG. An uneven pattern 3 composed of joint grooves 13 and pattern protrusions 14 is repeatedly applied in the longitudinal direction on the surface of a long panel 2 which is an original sheet manufactured by papermaking or paper making by a press such as a roller press or a press press. Like 2 (b), it is formed by cutting the long panel 2 at an arbitrary position in its longitudinal direction. Specifically, the uneven pattern 3 of this example is formed by arranging a plurality of block-shaped projections 14 having different sizes divided by joint grooves 13 in a top view, and the uneven pattern 3 is formed in the longitudinal direction. The building panel 1 is formed by cutting the long panel 2 repeatedly applied at a pitch unrelated to the pitch dimension of the concavo-convex pattern 3 in the longitudinal direction. Although the plurality of building panels 1 formed in this manner have the uneven pattern 3 in common, each of the building panels 1 has an uneven shape in which the uneven pattern 3 is shifted in a direction extending between the pair of cut end faces 5. Has to have. Thereafter, the building panel 1 is placed on the production line transport conveyor 15 and sent to the painting process. For example, as shown in FIG. For example, a finish is made by applying a coating that matches the concavo-convex shape of each building panel 1.

  Here, as the coating apparatus 8 used in the coating process of this example, a flexographic printing machine having a simple structure capable of repeatedly applying a predetermined coating pattern 6 is employed. As shown in FIG. 1, the coating apparatus 8 is carried by the coating process transport conveyor 16 that transports the building panel 1 delivered from the production line transport conveyor 15 in the coating apparatus 8, and the coating process transport conveyor 16. The coating roll 10 for coating the surface of the building panel 1, the anilox roll 17 for supplying ink to the coating roll 10, and the coating process conveying conveyor 16 at the coating position 24 of the coating roll 10 have the same upper surface. And a backup roll 18 arranged. Specifically, the peripheral surface of the coating roll 10 has a coating surface composed of a coating pattern 6 corresponding to the concave / convex pattern 3 common to the concave / convex shape of each building panel 1 formed as described above. The surface of the building panel 1 is painted by sandwiching the building panel 1 between 10 and the backup roll 18 and pressing the painted surface against the surface of the building panel 1. Here, the coating roll 10 and the anilox roll 17 are rotationally driven by a drive motor (not shown) that receives the drive control of the control unit 19. In addition, the painting process conveyor 16, the backup roll 18, and the production line conveyor 15 convey the building panel 1 and are operated at a constant speed, but the operation speed can be adjusted by inverter control. Yes.

  By the way, since the several building panel 1 formed as mentioned above has the uneven | corrugated pattern 3 in common, it is the coating means 7 (painting in this example) which paints with the coating pattern 6 corresponding to the uneven | corrugated pattern 3 If coating can be performed by the coating apparatus 8 having the roll 10), the coating finish can be performed with high productivity. However, the plurality of building panels 1 formed as described above have a concavo-convex shape such that the concavo-convex pattern 3 is shifted in a direction extending between the pair of cut end surfaces 5 for each building panel 1. That is, different concavo-convex shapes are formed on each building panel 1, but in this example, a plurality of building panels 1 are sequentially arranged on the coating pattern 6 of the coating means 7 according to the different concavo-convex shapes on each building panel 1. It has been devised to enable painting, and will be described in detail below.

  First, the reference mark 4 is provided on the surface of the building panel 1 so as to have a predetermined positional relationship with the concavo-convex pattern 3 in the stage before the conveyance of the building panel 1 to the painting process. In this example, as shown in FIG. 3, a reference mark 4 is provided at a position corresponding to an end portion on the extrusion direction side of the long panel 2 of the concavo-convex pattern 3. It consists of a through hole that penetrates in the direction. And this through-hole is formed by punching the long panel 2 in the thickness direction before forming the uneven pattern 3 on the long panel 2, and the position of the pressing position to the long panel 2 of the press die It is also used as a standard for matching. At least one reference mark 4 is provided on the building panel 1. In addition, in the pair of opposite side edge parts of the building panel 1 of this example, convex males for connecting the building panels 1 adjacent to each other when the building panel 1 is used (at the time of construction to the building). 12 and a concave female fruit 11 are formed between the pair of cut end faces 5, respectively. And the male 12 in the building panel 1 of this example is fitted and connected so as to be covered with the female 11 of the adjacent building panel 1 when the building panel 1 is used. A through hole constituting the reference mark 4 is formed in the female fruit 11. Therefore, the reference mark 4 is prevented from appearing on the exterior of the building when the building panel 1 is used, and the deterioration of the exterior of the building due to the reference mark 4 can be avoided.

  The plurality of building panels 1 are conveyed with a predetermined distance from the front and rear building panels 1 with their cut end faces 5 in the direction of travel, and a shape detection unit provided in front of the coating apparatus 8 20, the shape of each building panel 1 is detected. The shape detection unit 20 includes a detection unit 9 that detects the cut end surface 5 and the reference mark 4 of each building panel 1, an encoder 21 that measures the conveyance speed of the building panel 1, and the measurement results of the detection unit 9 and the encoder 21. The calculation unit 22 detects the shape of the building panel 1. The detection of the shape of the building panel 1 by the shape detector 20 will be described in detail below.

  The detection means 9 of this example uses a general-purpose photoelectric sensor disposed above the production line transport conveyor 15, and this photoelectric sensor is a male of the building panel 1 transported by the production line transport conveyor 15. The position through which the actual 12 passes is set as a measurement position, and irradiation light with a spot diameter of 0.1 mm or less is irradiated toward the measurement position, and the presence or absence of the building panel 1 at this measurement position can be detected. . When the detection means 9 detects a plurality of building panels 1 that are placed on the production line transport conveyor 15 and transported, an output result as shown in FIG. 5 can be obtained. Here, when the building panel 1 is detected at the measurement position in the photoelectric sensor, it is turned on, and when the building panel 1 is not detected at the measurement point 10a, the building panel 1 is placed on the production line conveyor 15. In the building panel 1 to be transported, the cutting end surface 5a on the transport front side of the building panel 1 whose measurement result changes from the off state to the on state, is turned off from the on state, and then immediately turned on. Thus, the reference mark 4 in which the measurement result changes, and the cut end surface 5b on the transported side of the building panel 1 in which the measurement result changes from the on state to the off state can be sequentially detected.

  Here, in this example, a contrivance is made to improve the detection accuracy by the photoelectric sensor constituting the detection means 9. The reference mark 4 in this example is specifically a through hole of about 3 × 10 mm, and is formed in a rectangular long hole shape that is long in the direction extending between the male fruit 12 and the female fruit 11 of the building panel 1. Therefore, the building panel 1 is shifted and conveyed in the width direction of the production line transport conveyor 15 (the same direction as the male fruit 12 and the female fruit 11 of the building panel 1), and the measurement position of the photoelectric sensor is manufactured. Even when the line conveying conveyor 15 is displaced in the width direction, the detection leakage of the reference mark 4 can be prevented as much as possible. When the through hole constituting the reference mark 4 is a circular hole or an elliptical hole, when the building panel 1 is transported out of alignment in the width direction of the production line transport conveyor 15 as described above, the measurement of the photoelectric sensor is performed. The detection position of the reference mark 4 is shifted in a direction extending between the pair of cut end surfaces 5 of the building panel 1 according to the shift of the position in the width direction of the production line transport conveyor 15. Since the detection position of 4 is formed in a rectangular long hole shape having a linear hole edge parallel to the direction extending between the pair of cut end faces 5 of the building panel 1, such a situation can be avoided. It is. In this example, although not shown, a guide roller for correcting the transport posture of the building panel 1 is provided at a position before the measurement position of the detection means 9 in the transport direction of the building panel 1. According to the guide roller, when the building panel 1 is transported on the production line transport conveyor 15 in a posture inclined in a horizontal plane from a predetermined transport posture, both ends of the building panel 1 having the male fruit 12 and the female fruit 11 are provided. The building panel 1 is corrected to a predetermined conveying posture by sandwiching the portion from both sides for a moment, and the male solid 12 of the building panel 1 is surely placed between the pair of cut end surfaces 5 on the measurement position of the detection means 9. It is trying to pass through.

  In addition, the encoder 21 is provided in the production line conveyor 15. According to this encoder 21, the encoder pulses output by increasing and decreasing according to the operation speed of the production line conveyor 15 (conveying speed of the building panel 1) are output. The moving distance of the production line conveyor 15 (the moving distance of the building panel 1) is determined by the number of measurements. In the calculation unit 22, the measurement result by the encoder 21, the detection result of the cut end surface 5 and the reference mark 4 of the building panel 1 detected by the detection means 9, and the positional relationship between the reference mark 4 and the uneven pattern 3. Based on the above, the position of the cut end face 5 in the concavo-convex pattern 3 is specified. Specifically, the movement within the time difference s depends on the number of encoder pulses measured at the time difference s between the detection end points 5a of the building panel 1 on the transport front side of the building panel 1 and the reference mark 4 detected by the detection means 9. The distance of the constructed panel 1, that is, the distance between the cut end surface 5 a on the transport front side of the building panel 1 and the reference mark 4 is obtained. And since the reference mark 4 and the uneven | corrugated pattern 3 have predetermined | prescribed positional relationship, the position of the cut end surface 5a before the conveyance of the building panel 1 in the uneven | corrugated pattern 3 is specified. Of course, in the calculation part 22, the building panel 1 in the uneven | corrugated pattern 3 by the measurement number of the reference mark 4 by the detection means 9, the cutting end surface 5b after conveyance of the building panel 1, and the encoder pulse measured within the time difference of a detection time. The position of the cut end surface 5b on the rear side of the sheet can also be specified. In addition, it is also preferable to provide the reference mark 4 at each position corresponding to the end portion of the long panel 2 in the extrusion direction of the concavo-convex pattern 3. In this case, the calculation unit 22 uses the detection means 9 to detect a single sheet. The number of concavo-convex patterns 3 included in the concavo-convex shape of a single building panel 1 can also be measured by the number of reference marks 4 detected during the measurement of the building panel 1. Furthermore, the reference mark 4 may be formed so as to punch out the male body 12 of the long panel 2 at the same time as press forming the uneven pattern on the long panel 2.

  The shape data of the building panel 1 obtained by the shape detection unit 20 as described above is sent to the control unit 19 that controls the coating means 7 of the coating apparatus 8. A coating start position 6 a is set in the coating pattern 6 of the corresponding coating roll 10. In addition, in the coating apparatus 8 of this example, the carrying-in detection means 25 which always detects the building panel 1 (the cut end surface 5a on the conveyance front side of the building panel 1) carried into the coating apparatus 8 at the carry-in entrance 23. And a measuring point 10a having a predetermined positional relationship with the coating pattern 6 is set on the coating roll 10, and a measuring point detecting means (not shown) provided in the coating apparatus 8 is used to measure the measuring point 10a. Rotation control of the coating roll 10 by the control part 19 is performed by always detecting. And in this coating apparatus 8, after detecting the building panel 1 conveyed by the carrying-in detection means 25, the coating pattern 6 is applied from the coating start position 6a to the building panel 1 reaching the coating position 24 of the coating roll 10. As described above, the control unit 19 performs the following control.

  When the carrying-in detection means 25 detects the building panel 1 to be conveyed, the control unit 19 calculates the time required for the building panel 1 to reach the building panel 1 from the carry-in entrance 23 of the coating apparatus 8 to the painting position 24. . Specifically, the arrival time of the building panel 1 is calculated based on the distance between the carry-in port 23 of the painting apparatus 8 and the painting position 24 and the conveyance speed of the building panel 1 (conveyance speed of the in-painting conveyor). . Further, the control unit 19 sets the coating start position 6a in the coating pattern 6 as described above, and calculates the distance difference between the position of the coating roll 10 corresponding to the coating start position 6a and the measurement point 10a. And, based on the rotational position of the measurement point 10a of the coating roll 10 detected by the measurement point detection means at the time of detection of the construction panel 1 by the carry-in detection means 25, the above-mentioned when the construction panel 1 is detected by the carry-in detection means 25 The rotation position (T in FIG. 1) of the coating roll 10 corresponding to the coating start position 6a is calculated, and when the coating roll 10 rotates at the normal rotation speed, the coating corresponding to the coating start position 6a is performed. The time required for the coating start position 6 a from when the position of the roll 10 rotates to the coating position 24 from when the construction panel 1 is detected by the carry-in detection means 25 is calculated. And when there is a time difference between the time required for reaching the building panel 1 calculated as described above and the time required for the painting start position 6a, the controller 19 causes the front side of the transported building panel 1 to be transported. Rotation control for decelerating or accelerating the drive motor of the coating roll 10 so that the coating start position 6a in the coating pattern 6 of the coating roll 10 is positioned in accordance with the timing at which the cut end surface 5a reaches the coating position 24 of the coating roll 10 is performed. It is done.

  Referring to FIG. 6, for example, the rotation position T of the coating roll 10 corresponding to the coating start position 6a in the coating pattern 6 when the building panel 1 is detected by the carry-in detection means 25 as shown in FIG. In the case of the point, as shown in FIG. 6B, the coating roll 10 is operated at a low speed for a predetermined time from the detection of the building panel 1 of the carry-in detection means 25, and then the coating roll 10 is operated at a normal speed. In this case, the point of the coating roll 10 reaches the coating position 24 at the same timing as when the cut end surface 5a on the transport front side of the building panel 1 reaches the coating position 24. Here, the normal speed operation is an operation based on the rotation speed of the coating roll 10 when painting the building panel 1. Similarly, when the rotation position T of the coating roll 10 corresponding to the coating start position 6a in the coating pattern 6 when the building panel 1 is detected by the carry-in detection means 25 as shown in FIG. As shown in FIG. 6 (c), in the case of a point C, as shown in FIG. 6 (d), the coating roll 10 is held for a predetermined time from the detection of the building panel 1 of the carry-in detection means 25, respectively. The coating roll 10 is returned to the normal speed operation at a low speed, and then the coating roll 10 is moved to the coating position 24 at the same timing as the cutting end surface 5a on the transport front side of the building panel 1 reaches the coating position 24. , Ha points to reach each. Moreover, when the rotation position T of the coating roll 10 corresponding to the coating start position 6a in the coating pattern 6 when the building panel 1 is detected by the carry-in detection means 25 as shown in FIG. As shown in FIG. 6E, when the point is a point, as shown in FIG. 6F, the coating roll 10 is moved at a high speed for a predetermined time from the detection of the building panel 1 of the carry-in detection means 25. After that, the coating roll 10 is returned to the normal rotation speed, and the coating roll 10 is moved to the coating position 24 at the same timing as the cutting end surface 5a on the transport front side of the building panel 1 reaches the coating position 24. The two points and the ho point reach each. In addition, although the coating roll 10 of this example is set to three speeds of operation speeds of low speed, normal speed, and high speed, it may be operated in multiple stages with more precise speed settings.

  As a result of the above, it is possible to apply the coating pattern 6 from the coating start position 6 a to the building panel 1 that reaches the coating position 24, that is, the coating corresponding to the uneven pattern 3. The painting means 7 for painting with the pattern 6 makes it possible to perform painting with good productivity according to the uneven shape of each building panel 1. The control for bringing the cut end surface 5a on the transport front side of the building panel 1 and the coating start position 6a of the coating roll 10 to the coating position 24 at the same timing is performed by increasing / decreasing the rotation speed of the coating roll 10. That is, since the conveyance speed of the building panel 1 can be made constant, the building panel 1 can be flowed to the production line without any delay, and the productivity of the building panel 1 is also improved in this respect. Moreover, since the increase / decrease control of the coating roll 10 is performed by the detection of the building panel 1 by the carrying-in detection means 25, the space | interval S before and behind the some building panel 1 sent to a manufacturing line like FIG. Needless to say, it is set to be longer than the distance L from the carry-in entrance 23 to the coating position 24. In addition, depending on the components of the coating material, there is a possibility that the coating roll 10 may swell. In such a case, the normal rotation speed of the coating roll 10 is controlled so as to be shifted from the conveyance speed of the building panel 1. The pitch of the concavo-convex pattern 3 and the pitch of the coating pattern 6 can be matched by adjusting by the part 19 and performing the coating by sliding the coating roll 10 on the building panel 1.

  In the above-described embodiment, the coating roll 10 is employed as the coating unit 7, but a spray-type coating unit 7 such as spraying ink may be employed. In the case of the coating means 7, the painting is performed by the program control of the painting pattern 6 preset in the control unit 19. The control unit 19 of the painting apparatus 8 performs the painting of the building panel 1 obtained by the shape detection unit 20. A coating start position 6a in the coating pattern 6 is set based on a detection position in the uneven pattern of the cut end surface 5a on the transport front side, and a time until the cut end surface 5a on the transport front side of the building panel 1 reaches the paint position 24 is calculated. The construction panel 1 obtained by the shape detection unit 20 is transported by applying the coating pattern 6 to the construction panel 1 from the painting start position 6a at the timing when the cut end surface 5a on the front side of the construction panel 1 reaches the painting position 24. A coating end position 6b in the coating pattern 6 is set based on the detection position in the concave / convex pattern on the rear cut end face 5b, and the rear cut end of the building panel 1 is conveyed. 5b calculates the time to reach the coating position 24, and finishes the coating at the coating end position 6b at the timing at which the cut end surface 5b on the rear side of the building panel 1 reaches the coating position 24. It is possible to perform painting according to. In the case where the reference mark 4 is provided for each concave / convex pattern 3, the number of the concave / convex patterns 3 of the building panel 1 is detected based on the number of detections of the reference mark 4 of the detection means 9. Based on this, it is also possible to control the number of times of painting of the painting pattern 6 from the start of painting to the end of painting.
