Description

The present invention relates to a building board forming machine that easily and quickly forms rising sections on both sides of the width of a building board, which have a continuous triangular cross-sectional mountain-shaped section along the longitudinal direction and an arc-shaped section along the longitudinal direction and on the horizontal plane.

Conventionally, architectural boards with continuous triangular ribs formed along the width direction and perpendicular to the longitudinal direction of the main board have been used as exterior structures such as roofs and walls for buildings such as large commercial facilities, factories, and gymnasiums. Such architectural boards are usually long, strip-shaped materials with flat main boards several meters to several tens of meters long.

Furthermore, some of these building boards are arched with an appropriate radius of curvature along the length and on the top and bottom surfaces, and are used to construct roofs with gentle curves or roofs with curves near the eaves. These building boards have vertical rising sections on both sides in the width direction, and multiple building boards are arranged in parallel and seam welded to the facing rising sections of adjacent building boards to construct the roof. There are also various types of forming machines that form building boards that are arched or have partial sections along the length.

However, in recent years, the appearance (design) of buildings has become more unique and complex. As a result, there is an increasing demand for architectural boards with ribbed ribs that run in the longitudinal direction and on horizontal surfaces. In other words, there is a demand for architectural boards that can be installed on roofs, walls, and other exterior structures in a gentle arc (curve) on horizontal surfaces.

JP 2001-30016 A

If a building board formed in a gentle arc (curve) along a horizontal plane like this is extremely long, over several tens of meters, it is extremely easy to artificially bend it in the longitudinal direction and on the horizontal plane. Therefore, such a building board that forms an arc on a horizontal plane can be manufactured as a long material in the longitudinal direction using a building board forming machine that can form normal ripples. In recent years, there has been a demand for building boards that form an arc along a horizontal plane and have rising portions on both sides of the width and along the longitudinal direction for roofs, walls, etc., not only for large-scale but also for the exterior enclosures of roofs, walls, etc. of medium-sized or smaller buildings.

However, when using a normal roll forming machine as a forming machine for forming rising portions along the longitudinal direction on both sides of a strip-shaped raw material with a ripple-like portion formed with a series of ribs perpendicular to the longitudinal direction, it is difficult to smoothly and accurately form the rising portions due to the arc shape of the raw material in the longitudinal direction and on a horizontal plane. Therefore, the problem (technical problem or purpose) that this invention aims to solve is to provide a building board forming machine that can smoothly and quickly form rising portions on both sides of the width direction and along the longitudinal direction of a building board that is arc-shaped along the longitudinal direction and on a horizontal plane.

Therefore, the inventors conducted intensive research to solve the above-mentioned problems, and as a result, the inventors have solved the above-mentioned problems by providing the invention of claim 1 as a building board forming machine comprising a plurality of upper and lower sets of forming roll sections that rise from a gentle incline to a vertical state on one side in the width direction, and a rise height adjustment device having a position regulating section that regulates the position of the raw material in front of the installation position of the first forming roll section, the rise height adjustment device making it possible to change the position along the width direction of the raw material when it is properly positioned, the raw material being shaped in an arc along the longitudinal direction and on the horizontal plane, and the rise sections forming the edges of one side and the other side of the raw material in the width direction in sequence one by one by the forming roll sections, and two rise height adjustment devices are provided, one of which has the position regulating section positioned toward the outer side in the width direction, and the other of which has the position regulating section positioned toward the inner side in the width direction .

The above problem has been solved by providing an architectural plate forming machine according to the invention of claim 2, which comprises a plurality of upper and lower sets of forming roll sections that rise from a gentle incline to a vertical state on one side in the width direction, and a rise height adjustment device having a position regulating section for regulating the position of the raw material in front of the installation position of the first forming roll section, the rise height adjustment device making it possible to change the position along the width direction of the raw material when it is properly positioned, the raw material being shaped in an arc along the longitudinal direction and on the horizontal plane, and the rise sections forming the edges of one side and the other side of the width direction of the raw material one by one in sequence by the forming roll section, the rise height adjustment device being one device and having an attachment section that is configured to move and be fixed in the width direction, and a pressure roll being provided in front of the rise height adjustment device .

The invention of claim 3 solves the above problem by providing a building board forming machine as described in claim 2, characterized in that the rising height adjustment device has two presser rolls arranged in parallel along the feed direction.

The invention of claim 4 solves the above problem by providing a building board forming machine according to any one of claims 1, 2, and 3, characterized in that the roll forming sections include a first roll forming section that rises gently on one side in the width direction, a second roll forming section that rises from a gentle slope to a steep slope, and a third roll forming section that rises from a steep slope at a right angle.

In the invention of claim 1, a building board forming machine is provided with a set of upper and lower forming roll sections that rise from a gentle incline to a vertical position along the feed direction of the raw material at a position on one side of the width direction (sometimes called the Y direction) of the properly arranged raw material. In addition, in front of the installation position of the first forming roll section, there is a rise height adjustment device that has a position regulation section that regulates the position of the raw material in the width direction (Y direction).

The raw material is formed in an arc shape along the longitudinal direction and on the horizontal plane. In the building board forming machine, such raw material can be appropriately positioned and its position can be changed along the width direction, and the forming roll section forms the rising portions on one side and the other side of the raw material in the width direction, one by one, in order. As a result, the rising portions are formed in the width direction of the raw material one by one in order, and the rising portions can be formed with extremely high precision without applying excessive load to the raw material.

In addition, by configuring the rise height adjustment device so that the position along the width direction of the raw material can be changed or moved freely, the distance between the forming roll section and the edge of the raw material in the width direction can be adjusted as appropriate, and the height dimension of the rise portion can be set to the desired dimension. As a result, the height dimension of one of the two rise portions in the width direction of the building board formed from the raw material through the building board forming machine can be set large and high, and the height dimension of the other rise portion can be set small and low, and in the construction of a roof, etc., one of the rise portions of adjacent building boards of parallel building boards can be made high and the other low, and the upper end of the high rise portion can be folded back to cover the top of the other rise portion, improving roof construction.

Furthermore, in the invention of claim 1 , the architectural plate forming machine is provided with two rise height adjustment devices, one with the position regulating part located on the outer side in the width direction and the other with the position regulating part located on the inner side in the width direction, and by using the two rise height adjustment devices respectively, the heights of the rise portions formed on both sides in the width direction of the raw material can be made different.

In the invention of claim 2 , the rise height adjustment device is a single device having an attachment part, and the attachment part is configured to be appropriately moved and fixed in the width direction (Y direction), so that rise parts with different height dimensions can be easily made on both sides of the width direction (Y direction) of the raw material. Furthermore, in the invention of claim 2 , a press roll is provided in front of the rise height adjustment device, so that vertical vibration of the raw material during roll forming can be suppressed, and stable forming work can be performed.

In the invention of claim 3 , the press rolls provided in the rise height adjustment device are configured as two press rolls arranged in parallel along the feed direction, which further suppresses vertical vibration of the raw material during forming. In the invention of claim 4 , the multiple roll forming sections include a first roll forming section that rises at a gentle slope on one side in the width direction, a second roll forming section that rises from the gentle slope to a steep slope, and a third roll forming section that rises at a right angle from the steep slope, which enables accurate formation of the rise section.

The following describes an embodiment of the present invention with reference to the drawings. First, the building board 9 formed by the building board forming machine of the present invention is formed on a raw material P of a thin, flat, band-shaped metal plate, with mountain-shaped portions with triangular cross sections continuing in a roughly zigzag pattern along the longitudinal direction of the raw material, and with an arc shape along the longitudinal direction and on the horizontal plane of the band-shaped metal plate (see FIG. 5). The arc shape may also be called a curved shape or a crescent shape.

The raw material P is a metal strip several meters (less than about 10 meters) to several tens of meters long, and is wound in a roll before being formed into a building board 9. The building board 9 formed from the raw material P by the building board forming machine of the present invention has a series of mountain-shaped portions with triangular cross sections arranged in a roughly zigzag pattern along its length, and is formed in an arc along the length and on the horizontal plane. Figure 4(B) shows the overall shape of the building board 9, with the length of the building board 9 being L and the amount of deflection (camber) due to the arc on the horizontal upper surface being s.

The zigzag-like mountain-shaped portions of the architectural board 9, each of which has a triangular cross section, are called ribs 91, and the group of continuous ribs is called a "ripple." When the architectural board 9 is actually used to construct an exterior structure such as a roof or wall, a substantially vertical rising portion is formed on both sides in the width direction (Y direction). A number of architectural boards 9 processed in this manner are arranged in parallel on the base, and the rising portions 92, 92 of adjacent architectural boards 9 are abutted against each other and fixed to each other by a fixing means such as seam welding, and an exterior structure such as a roof or wall is constructed (see FIG. 6(D)).

In addition, one of the two rising portions 92 on both sides of the width direction (Y direction) of the building board 9 may be formed slightly higher than the other. The part of the two rising portions 92, 92 that is formed higher than the other is folded back downward to cover the upper end of the other rising portion 92 and to prevent the upper end of the connected rising portion 92 from becoming sharp (see Figure 6 (D)).

The building board 9 formed by the building board forming machine of the present invention is finished from raw material P. Both sides of the raw material P in the width direction (Y direction) are flat, and ripples are formed on the entire surface. The raw material P is formed into an arc shape along the longitudinal direction and on the horizontal plane while ripples are formed by another forming machine prior to forming by the building board forming machine of the present invention, and is provided with camber (warping or bending) s (see FIG. 4(A)). The raw material P is formed into an arc shape along the longitudinal direction and on the horizontal plane, and here, the building board 9 has a small diameter side and a large diameter side, and the small diameter side is called the small diameter side Ma and the large diameter side is called the large diameter side Mb (see FIG. 5).

In the raw material P, on the small diameter side Ma side, the height dimension Ha of the rib 91 is maximum, and the pitch dimension Ka between adjacent ribs 91 is minimum (see Figures 5 (A), (B), and (D)). On the large diameter side Mb side, the height dimension Hb of the rib 91 is minimum, and the pitch dimension Kb between adjacent ribs 91 is maximum. The pitch dimension of the rib 91 may be equal to the width dimension of the rib 91 in the longitudinal direction of the raw material P (see Figures 5 (B) and (C)). In this state, the raw material P on which the rib 91 is formed is formed so as to be arc-shaped in the longitudinal direction and on the horizontal plane (see Figures 4 and 5 (A)).

In the description of the building board forming machine of the present invention, there are the terms X direction and Y direction as terms indicating directions. The X direction is the direction in which the raw material P is fed into the building board forming machine of the present invention and moves during the forming process. In addition, when the raw material P and the building board 9 are placed in the building board forming machine, the longitudinal direction of the raw material P and the building board 9 is the X direction. In this state, the X direction of the building board forming machine is the same as the X direction of the raw material P and the building board 9 (see Figure 1).

The Y direction is the width direction of the raw material P when the raw material P is properly placed in the building board forming machine, and in this state, the Y direction of the building board forming machine is the same as the Y direction of the raw material P. Also, in the X direction of the building board forming machine, the side into which the raw material P is fed is the front side, and the side from which the raw material P is formed and sent out as the building board 9 is the rear side.

The building board forming machine of the present invention serves to form rising portions 92, 92 on both sides in the width direction of raw material P, which is arc-shaped in the longitudinal direction and on the horizontal plane and has ripples formed therein, to form a building board 9. As shown in Figure 1, the building forming machine is mainly composed of multiple forming roll sections A, a raw material feed bed 82, a rising height adjustment device 3, a raw material presser 5, a drive motor 7, and a machine frame 8 (see Figure 1). Here, there is a forming and feeding direction of the raw material P in the building forming machine.

The raw material feed direction is the direction in which the raw material P moves when it is fed into the building board forming machine and the rising portion 92 is formed, and coincides with the X direction. The side where the raw material P starts to move by the building board forming machine is called the front side, and the side where it is fed out is called the rear side. The raw material feed direction coincides with the long dimension direction (also called the longitudinal direction) of the raw material P, and the width direction of the raw material P is called the Y direction. The X and Y directions also apply to the building board forming machine when it is assumed that the raw material P is properly installed (see Figure 1).

In the multiple forming roll sections A, A, ..., each forming roll section A has an upper forming roll and a lower forming roll, which are configured as an upper and lower pair. The multiple forming roll sections A, A, ... are arranged in a row along the X direction, forming a group, only on one side of the width direction (Y direction) of the raw material P that is properly arranged in the building board forming machine. In other words, a plurality of multiple forming roll sections A, A, ... are provided, and the multiple forming roll sections A, A, ... are arranged in a row along the X direction, only on one side of the width direction (Y direction) of the raw material feed bed 82 of the building board forming machine.

The multiple forming roll sections A, A, ... gradually raise the rising portion 92 from a gentle slope to a vertical shape. As the raw material P passes through the multiple forming roll sections A, the rising portions 92 are formed one by one at the width direction (Y direction) ends of the raw material P. In other words, the building board forming machine of the present invention positions either the small diameter side Ma side or the large diameter side Mb side of the raw material P in the group of forming roll sections A, A, ... to form the rising portion 92, then turns the raw material P over and sends it back into the building board forming machine, where the other side is positioned in the forming roll sections A, A, ... to form the rising portion 92 (see Figure 4).

For example, a rising portion 92 is formed on the small diameter side Ma of the raw material P in a building board forming machine, and when the raw material P is completely fed out of the building board forming machine, the raw material P is turned over, this time with the large diameter side Mb positioned on the forming roll section A side, and fed into the building board forming machine again. In this way, rising portions 92, 92 are formed on both sides of the width direction (Y direction) of the raw material P, and the formation of the building board 9 is completed.

As described above, a plurality of roll forming units A are provided along the X direction to form a group of roll forming units A, and the roll forming units A each have a different shape of forming roll. Two or more roll forming units A are provided. In the embodiment of the present invention, a configuration in which three sets of roll forming units A are provided is described (see Figures 1 and 2).

When there are three sets of roll forming units A, they are referred to as the first roll forming unit A1, the second roll forming unit A2, and the third roll forming unit A3 in the order in which they perform roll forming on the raw material P. In other words, they are arranged in the order of the first roll forming unit A1, the second roll forming unit A2, and the third roll forming unit A3 from the front to the rear in the X direction. The first roll forming unit A1, the second roll forming unit A2, and the third roll forming unit A3 are arranged in a group along the X direction. In addition, in the group of roll forming units A, A, ... described above, the forming roll unit A located first is the first roll forming unit A1.

The first roll forming section A1, the second roll forming section A2, and the third roll forming section A3 are provided only on one side of the width direction (Y direction) of the raw material feed bed 82 [see FIG. 1(A)]. In other words, the first roll forming section A1, the second roll forming section A2, and the third roll forming section A3 are provided only on one side of the width direction (Y direction) of the raw material P that is properly placed on the raw material feed bed 82. As a result, the building board forming machine forms a rising portion 92 only on one side of the small diameter side Ma or the large diameter side Mb in the width direction (Y direction) of the raw material P in the first pass.

The first roll forming section A1 has a first upper forming roll 11 and a first lower forming roll 21, the second roll forming section A2 has a second upper forming roll 12 and a second lower forming roll 22, and the third roll forming section A3 has a third upper forming roll 13 and a third lower forming roll 23 (see Figures 1(B) and 3).

In the first roll forming section A1, the first upper forming roll 11 and the first lower forming roll 21 are arranged in parallel in the vertical direction to form a pair (see Fig. 1(B) and Fig. 3(B)). The first upper forming roll 11 is formed in a disk shape with a flat outer peripheral side surface 11a. The first lower forming roll 21 is a roll in which an approximately conical inclined outer peripheral side surface 21b and a flat outer peripheral side surface 21a are provided in succession.

The first lower forming roll 21 is formed with a smaller diameter than the first upper forming roll 11, specifically, the diameter of the first lower forming roll 21 is approximately half the diameter of the first upper forming roll 11. The inclined outer peripheral side surface 21b of the first lower forming roll 21 has a small, gentle inclination angle with respect to the axial direction, specifically, approximately 30 degrees or less, and further, this angle may be set appropriately depending on the situation.

The flat outer peripheral side surface 11a of the first upper forming roll 11 and the flat outer peripheral side surface 21a of the second lower forming roll 22 are in the same position in the axial direction, and the inclined outer peripheral side surface 21b is positioned adjacent to and outside the flat outer peripheral side surface 21a in the axial direction (see FIG. 1(B)). The first upper forming roll 11 is equipped with a rotating shaft 11c, and the first lower forming roll 21 is equipped with a rotating shaft 22c.

Either the first upper forming roll 11 or the first lower forming roll 21 is driven to rotate by a motor, and it is preferable that the first lower forming roll 21 is driven to rotate. The raw material P passing between the first upper forming roll 11 and the first lower forming roll 21 of the first roll forming section A1 is pressed vertically when passing between the flat outer peripheral side surface 11a of the first upper forming roll 11 and the flat outer peripheral side surface 21a of the first lower forming roll 21, and the width direction end of the raw material P is raised upward at a gentle incline from the horizontal by the inclined outer peripheral side surface 21b of the first lower forming roll 21 [see FIG. 3(B)].

The second upper forming roll 12 and the second lower forming roll 22 in the second roll forming section A2 have substantially the same configuration as the first upper forming roll 11 and the first lower forming roll 21 of the first upper forming roll 11. Regarding the second upper forming roll 12 and the second lower forming roll 22, the second upper forming roll 12 and the second lower forming roll 22 are arranged in parallel in the vertical direction (see FIG. 3(C)).

The second upper forming roll 12 is formed in a disk shape having a flat outer peripheral side surface 12a. The second lower forming roll 22 is a roll in which a generally conical inclined outer peripheral side surface 22b and a flat outer peripheral side surface 22a are continuously provided. The second lower forming roll 22 is formed with a smaller diameter than the second upper forming roll 12, and specifically, the diameter of the second lower forming roll 22 is approximately half the diameter of the second upper forming roll 12 [see FIG. 3(C)].

The inclined outer peripheral side surface 22b of the second lower forming roll 22 has a steeper inclination angle with respect to the axial direction than the inclination angle of the inclined outer peripheral side surface 21b of the first lower forming roll 21, specifically in the range of about 60 degrees. The second upper forming roll 12 is equipped with a rotating shaft 12c, and the second lower forming roll 22 is equipped with a rotating shaft 22c. The rest of the configuration is the same as that of the first upper forming roll 11 and the second lower forming roll 21. The raw material P passing between the second upper forming roll 12 and the second lower forming roll 22 of the second roll forming section A2 is formed such that the width direction end of the raw material P is raised upward at a steep incline with respect to the horizontal by the inclined outer peripheral side surface 22b of the second lower forming roll 22.

The third upper forming roll 13 and the third lower forming roll 23 in the third roll forming section A3 have substantially the same configuration as the first upper forming roll 11 and the first lower forming roll 21 in the first roll forming section A1. Regarding the third upper forming roll 13 and the third lower forming roll 23, the third upper forming roll 13 and the third lower forming roll 23 are arranged in parallel in the vertical direction (see FIG. 3(D)).

The third upper forming roll 13 is formed in a disk shape with a flat outer peripheral side surface 13a. The third lower forming roll 23 is a roll in which a roughly conical inclined outer peripheral side surface 23b and a flat outer peripheral side surface 23a are continuously provided. The third lower forming roll 23 is formed with a smaller diameter than the third upper forming roll 13, and specifically, the diameter of the third lower forming roll 23 is roughly half the diameter of the third upper forming roll 13 (see FIG. 3(D)).

The inclined outer peripheral side surface 23b of the third lower forming roll 23 is a vertical surface (including a nearly vertical surface). In other words, the range of inclination of the inclined outer peripheral side surface 23b includes vertical (almost vertical). The third lower forming roll 23 is configured with two continuous disks of different diameters. The third upper forming roll 13 is equipped with a rotating shaft 13c, and the third lower forming roll 23 is equipped with a rotating shaft 23c.

The rest of the configuration is the same as that of the first upper forming roll 11 and the second lower forming roll 21. The raw material P passing between the third upper forming roll 13 and the third lower forming roll 23 of the third roll forming section A3 is formed such that the width direction end of the raw material P is raised upward at a right angle (including approximately a right angle) to the horizontal by the approximately vertical inclined outer peripheral side surface 23b of the third lower forming roll 23, and the forming of the raised portion 92 is completed in a state where the raw material P is raised at an approximately right angle.

The diameters of the flat outer peripheral sides 21a, 22a, 23a of the first lower forming roll 21, the second lower forming roll 22, and the third lower forming roll 23 may be the same (or approximately the same). With this configuration, when the raw material P passes through the first roll forming section A1, the second roll forming section A2, and the third roll forming section A3, the raw material P always remains horizontal, and a stable feed state can be achieved.

Next, the rising height adjustment device 3 will be described. The rising height adjustment device 3 serves to properly position the raw material P on the raw material feed bed 82 of the building board forming machine of the present invention, and to accurately and properly feed it along the X direction to the first forming roll section A, i.e., the first roll forming section A1, and to set the height of the rising portion 92. In other words, it serves to determine the position of one end side where the rising portion 92 is formed in the width direction (Y direction) of the raw material P, and to set the height dimension of the rising portion 92.

The rising height adjustment device 3 is located at the front side of the first forming roll section A, i.e., the first roll forming section A1, in the raw material feed direction of the raw material P. The rising height adjustment device 3 is basically composed of a position regulation section 31 and an attachment section 32. The position regulation section 31 is formed in a vertical plate shape, and the attachment section 32 is formed in a horizontal plate shape. There are two embodiments of the rising height adjustment device 3, and in the first embodiment, two rising height adjustment devices 3 are provided (see FIG. 3(E)). In the second embodiment of the rising height adjustment device 3, only one rising height adjustment device is provided (see FIG. 3(F)).

First, in the first embodiment of the rising height adjustment device 3, two rising height adjustment devices 3 are provided. The position regulating unit 31 of one rising height adjustment device 3 is located toward the outer side in the width direction (Y direction) of the raw material feed bed 82, and the position regulating unit 31 of the other rising height adjustment device 3 is located toward the inner side in the width direction (Y direction) of the raw material feed bed 82. The outer side in the width direction (Y direction) of the raw material feed bed 82 refers to the side that is away from the width direction (Y direction) of the raw material feed bed 82. Also, the inner side in the width direction (Y direction) of the raw material feed bed 82 refers to the side that is close to the end of the width direction (Y direction) of the raw material feed bed 82.

In other words, the two rise height adjustment devices 3 set the rise amount K of the rise portion 92, described later, to two different levels, high and low (see FIG. 3(E)). In the two rise height adjustment devices 3, the position regulating portion 31 is a vertical plate, and the position regulating portion 31 that sets the rise amount K high has a single plate shape (see FIG. 3(E)(I)). In addition, the position regulating portion 31 that sets the rise amount K low is provided on the surface where the adjustment plate piece 31a abuts against the end of the raw material P in the width direction (Y direction) (see FIG. 3(E)(II)).

The thickness of the adjustment plate piece 31a is set according to the rise amount K of the rising portion 92. The adjustment plate piece 31a may also be formed integrally with the position regulating portion 31. In other words, the adjustment plate piece 31a may change the thickness by making the position regulating portion 31 stepped. The two rise height adjustment devices 3 set the rise amount K, which is the distance between the rise reference line J (described later) and the position regulating portion 31, to two types: high and low.

In the building board forming machine of the present invention, the position regulating unit 31 determines the position of the end edge on the side where the rising portion 92 in the width direction (Y direction) of the raw material P is formed and the rising amount K of the rising portion 92 when the raw material P is properly positioned on the raw material feed bed 82. The raw material P has a small diameter side Ma side and a large diameter side Mb side on both sides in the width direction (Y direction), and the rising height adjustment device 3 can accommodate either side.

The mounting portion 32 is a portion where the rise height adjustment device 3 is attached to the machine frame 8, and is fixed by fasteners such as bolts and nuts. In the first embodiment, the through hole 32a of the mounting portion 32 for fasteners such as bolts and nuts is a circular hole that is slightly larger than the bolt diameter, and the structure does not allow the position of each mounting portion 32 of the two rise height adjustment devices 3 to be adjusted relative to the machine frame 8.

In the second embodiment of the rise height adjustment device 3, one rise height adjustment device is provided, and the mounting portion 32 is configured to move and be fixed along the width direction (Y direction) of the building plate forming machine (see FIG. 3(F)). In this embodiment, the through hole 32b of the mounting portion 32 for fasteners such as bolts and nuts is a long hole formed long along the width direction (Y direction). The mounting portion 32 has a long through hole 32b and fasteners such as bolts and nuts, and the through hole 32b, which is a long hole in the loosened state, can adjust the position of the position regulating portion 31 of the rise height adjustment device 3 in the width direction (Y direction). This allows the rise amount K of the rise portion 92 to be adjusted and set to a desired amount by one rise height adjustment device 3.

The rising height adjustment device 3 in either the first or second embodiment sets the height dimension, or rising amount K, of the rising portion 92 to be formed on the raw material P, and first appropriately sets the position of the position regulating unit 31 in the width direction (Y direction) of the building board forming machine. Specifically, the position of the outer peripheral edge 11t in the width direction (Y direction) of the first upper forming roll 11 of the first roll forming unit A1 becomes the position where bending of the rising portion 92 to be formed on the raw material P begins.

The position of the outer peripheral edge 11t in the width direction (Y direction) of the first upper forming roll 11 is the left edge of the first upper forming roll 11 in Figures 2 (C), (E) and 3 (B). A line extending vertically from the peripheral edge 11t of the first upper forming roll 11 is the rising reference line J. The distance between the rising reference line J and the position regulating portion 31 is the rising amount K. The rising amount K is the height dimension of the rising portion 92 of the building board 9 (see Figures 2 (C) to (F) and Figure 3).

The rising reference line J is fixed due to the outer peripheral edge 11t of the first upper forming roll 11, and the position regulating unit 31 is variable in the width direction (Y direction) of the building board forming machine, so that the position can be changed as appropriate. When the rising portion 92 of the raw material P is set high, the rising amount K is increased (see Figs. 2(C) and (D)). When the rising portion 92 of the raw material P is set low, the rising amount K is set small (see Figs. 2(E) and (F)D). This allows one of the rising portions 92, 92 on both sides of the building board 9 in the width direction (Y direction) to be set higher or lower than the other rising portion 92.

In some embodiments, a pressure roll 4 is provided in front of the rising height adjustment device 3. The pressure roll 4 has a position regulation section 31 that extends forward, and the pressure roll 4 is attached to the position regulation section 31. Two pressure rolls 4 may also be provided in parallel. In the molding machine of the present invention, the first roll forming section A1, the second roll forming section A2, and the third roll forming section A3 are driven by a transmission means such as an electric motor 7 and a chain drive 71.

Reference numeral 5 denotes a raw material holder. The raw material holder 5 is provided on the machine frame 8, and together with the rise height adjustment device 3, serves to accurately position the raw material P on the raw material feed bed 82 and to prevent misalignment in the width direction (Y direction) during roll forming of the rise portion 92. The raw material holder 5 is composed of a tip holder 51 and an extension adjustment unit 52 equipped with a screw shaft and a handle, and the tip holder 51 moves along the width direction (Y direction) of the building board forming machine by operating the extension adjustment unit 52. The raw material P is supported in a guided state on both sides of the width direction (Y direction) on the raw material feed bed 82 by the position regulating unit 31 of the rise height adjustment device 3 and the tip holder 51 of the raw material holder 5.

In addition to the semi-circular arc-shaped building board 9 formed from the raw material P according to the present invention, there is also a roughly S-shaped curve with two continuous arc-shaped regions, a convex one and a concave one [see Figs. 6(A) and (B)]. When forming this S-shaped building board 9, first, a building board forming machine forms ripples up to the middle position in the longitudinal direction of the raw material P to form a convex arc-shaped region. Then, the raw material P is temporarily removed from the building board forming machine, and the building board forming machine is used again to form ripples in the region where no ripples are formed, forming a concave arc-shaped portion. Fig. 6(A) shows a roof consisting of a building board 9 consisting of one arc and a S-shaped building board 9 having two arcs, and Fig. 6(C) shows a house such as a factory, warehouse, or commercial facility using this roof.

The use of the building plate forming machine in the present invention will be described. The raw material P is arc-shaped in the longitudinal direction and on the horizontal plane, and has a small diameter side Ma and a large diameter side Mb in the width direction (Y direction). In order to form a rising portion 92 in the raw material P in the building plate forming machine, the rising portion 92 is formed on one side of either the small diameter side Ma or the large diameter side Mb, and then the rising portion 92 is formed on the other side.

More specifically, the raw material P is placed on the raw material feed bed 82 of the building board forming machine. At this time, either the small diameter side Ma side or the large diameter side Mb side of the raw material P is positioned on the forming roll group A side, and the forming roll group A is started to form a rising portion 92 on one side of the width direction (Y direction) of the raw material P. When the first forming of the rising portion 92 for the raw material P is completed and the raw material P is completely sent out from the building board forming machine, the raw material P is turned over on a horizontal plane. Next, the turned raw material P is sent back to the building board forming machine, and the other side side is positioned at the forming roll group A, A, ... to form the rising portion 92, so that the rising portions 92, 92 are formed on both sides of the width direction (Y direction) of the raw material P, and the forming of the building board 9 is completed (see FIG. 4).

For example, in a building board forming machine, a rising portion 92 is formed from the small diameter side Ma of the raw material P, and when the raw material P has been completely sent out from the building board forming machine, the raw material P is then inverted and positioned so that the large diameter side Mb is on the forming roll section A side, and is sent back into the building board forming machine. In this way, rising portions 92, 92 are formed on both sides of the width direction (Y direction) of the raw material P, and the formation of the building board 9 is completed.
