The protruding corner material manufacturing method of the present invention includes a cutting step of cutting the second substrate so as to be aligned with the back surface of the first substrate. Therefore, the projected corner material produced by the projected corner material manufacturing method of the present invention has a plate shape and is easier to pack than the L-shaped projected corner material. Further, since the projected corner material produced by the projected corner material manufacturing method of the present invention has a plate shape, a dead space is less likely to occur when packed in a box as compared with the L-shaped projected corner material. In another method for producing a cornering material of the present invention, the second substrate and the third substrate can be cut so as to be aligned with the back surface of the first substrate. Therefore, the protruding corner material produced by another method for producing the protruding corner material of the present invention has a plate shape and is easier to pack than the U-shaped protruding corner material. Further, since the projected corner material produced by the projected corner material manufacturing method of the present invention has a plate shape, a dead space is less likely to occur when packed in a box as compared with a U-shaped projected corner material.

The protruding corner material manufacturing method of the present invention includes a bonding step of joining another other end of the first substrate and another end of the second substrate together. Therefore, the projected corner material produced by the projected corner material manufacturing method of the present invention does not need to be shaped in appearance unlike the projected corner material manufacturing method of Patent Document 1, and therefore, the projected corner material manufacturing method of Patent Document 1 It can be manufactured at a lower cost than the above.

The protruding corner material manufacturing method according to an embodiment of the present invention includes a removing step of removing an adhesive leaking out from an adhesive portion between another other end of the first substrate and another end of the second substrate. doing. Therefore, the projected corner material produced by this projected corner material manufacturing method does not have insufficient adhesive and poor adhesion. The same applies to the protruding corner material manufacturing method in another embodiment of the present invention.

In the method for producing a corner material according to an embodiment of the present invention, when the adhesive is removed in the removing step, a part of the first substrate and a part of the second substrate are removed. Therefore, it is possible to remove the corners of the protruding lumber that cause damage in advance. In addition, when removing the adhesive, it is not necessary to work so as not to damage the corners of the protruding corner material, so this method of manufacturing the protruding corner material removes the adhesive as compared with the work of removing only the adhesive. You can increase the speed of doing. The same applies to the protruding corner material manufacturing method in another embodiment of the present invention.

The method for producing a corner material according to an embodiment of the present invention is a part of the first substrate and one of the second substrates removed after the removal step of removing the adhesive and a part of the first substrate and the second substrate. It includes a coloring step of coloring a part. Therefore, it is possible to prevent the viewer from feeling a sense of discomfort in the scraped portions of the first substrate and the second substrate. The same applies to the protruding corner material manufacturing method in another embodiment of the present invention.

In the method for producing a corner material according to an embodiment of the present invention, after the removal step of removing the adhesive and a part of the first substrate and the second substrate, the removed portion of the first substrate and the second substrate is removed. It includes a coloring step of coloring with substantially the same color as the first substrate and the second substrate. Therefore, the scraped portions of the first substrate and the second substrate look the same as the surfaces of the first substrate and the second substrate, and the commercial value of the projected corner lumber is increased. The same applies to the protruding corner material manufacturing method in another embodiment of the present invention.

In the protruding corner material manufacturing method according to an embodiment of the present invention, in the cutting step, the bonded first substrate and second substrate are conveyed, and a part of the second substrate is cut by a cutting device in a substantially horizontal plane.

If a part of the second substrate is cut in the vertical direction, the surface of the second substrate faces upward, the surface of the first substrate flows sideways, and the portion cut by the weight of the first substrate and the principle of leverage is formed. The cutting portion of the second substrate remaining on the first substrate is slightly increased, and the cutting end is cut deeper by the cutting device than the cutting portion at the beginning of cutting. However, when a part of the second substrate is cut in the lateral direction, the cut surface of the second substrate adhered to the first substrate is cut neatly and straightly.

Further, when a part of the second substrate is cut in the lateral direction, the surface of the first substrate faces upward and flows, so the manufacturer should work while checking the appearance of the first substrate having a large area. And can sort out defective products.

Further, when a part of the second substrate is cut in the lateral direction, the surface of the first substrate flows upward, so that the manufacturer can perform the flow with the surface of the first substrate lying down. Easy to work. For example, when the manufacturer accumulates the cut corners, the corners with the surface facing upward may be picked up and moved. The same applies to the protruding corner material manufacturing method in another embodiment of the present invention.

In the manufacturing apparatus of the present invention, a part of the second substrate is cut so as to be aligned with the back surface of the first substrate on a surface whose normal direction is the vertical direction.

If a part of the second substrate is cut in the vertical direction, the surface of the second substrate faces upward, the surface of the first substrate flows sideways, and the portion to be cut is small due to the weight of the first substrate and the principle of leverage. The cut portion of the second substrate remaining on the first substrate is cut deeper by the cutting device at the end of cutting than at the beginning of cutting. However, when a part of the second substrate is cut in the lateral direction, the cut surface of the second substrate adhered to the first substrate is cut neatly and straightly.

Further, when a part of the second substrate is cut in the lateral direction, the surface of the first substrate flows upward, so that the manufacturer works while checking the appearance of the surface of the first substrate having a large area. It is possible to sort out defective products.

Further, when a part of the second substrate is cut in the horizontal direction, the surface of the first substrate faces upward and flows, so that the manufacturer can compare the case where the surface of the first substrate faces sideways and flows. Easy to work. For example, when the manufacturer accumulates the cut corners, the corners with the surface facing upward may be picked up and moved.

When the cutting device cuts a part of the second substrate on the back surface of the first substrate, if the first guide and the second guide guide the intermediate member in the vicinity of the cutting device, the cutting device cuts with an error of 0. The vessel will cut a part of the second substrate, which will lead to blade spillage of the cutter. However, in the manufacturing apparatus according to an embodiment of the present invention, the first guide has a first notch portion and the second guide has a second notch portion in order to arrange the cutting device. Therefore, in this manufacturing apparatus, the cutting device does not come into contact with the guide and the blade does not spill. The same applies to the other manufacturing apparatus of the present invention.

In the manufacturing apparatus according to an embodiment of the present invention, the second feed portion is arranged at the lower part of the cutting device. Therefore, even if a strong force is applied to the second substrate, the surface of the projected corner material to be a product is not damaged. Further, since the second feed unit presses the second substrate against the second guide at the lower part of the cutting device, the vibration generated by the cutting device can be efficiently absorbed. The same applies to the manufacturing apparatus according to another embodiment of the present invention.

In the manufacturing apparatus according to an embodiment of the present invention, the cutting machine is a circular saw. Therefore, this manufacturing apparatus can simplify the mechanism as compared with a reciprocating saw. The same applies to the manufacturing apparatus according to another embodiment of the present invention.

Hereinafter, a method for manufacturing a projected corner lumber according to the first embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a flow chart showing a method of manufacturing a projected corner lumber according to the first embodiment of the present invention. Further, FIG. 2 is an external view showing an example of the first substrate 10 and the second substrate 20.

The manufacturer prepares the first substrate 10 and the second substrate 20 as shown in FIG. 2 (step S10). The first substrate 10 and the second substrate 20 may be cut out from one substrate. The substrate faces the front surfaces 11, 21, the back surfaces 12, 22, the one ends 13, 23, the other ends 14, 24 facing the one ends 13, 23, the other end 15, and the other end 15. It has another other end 26. The portion sandwiched between the other end 16 and the other end 25 is a portion cut off when the first substrate 10 and the second substrate 20 are cut out.

First fitting portions may be formed at one ends 13 and 23 of the substrates in order to connect the substrates to each other. Further, in order to connect the substrates to each other, a second fitting portion may be formed at the other ends 14 and 24 of the substrates. In that case, the first fitting portion of one substrate can be fitted with the second fitting portion of the other substrate.

As the shape of the fitting portion, a kanhe or a real thing may be used. For example, the front surface of the substrate may be longer than the back surface of the substrate near one end of the substrate, and the front surface of the substrate may be shorter than the back surface of the substrate near the other end of the substrate. Further, a convex portion may be provided at one end of the substrate, and a concave portion may be provided at the other end of the substrate.

The main material of the substrate may be a cementum material. In addition, the substrate may contain at least one of fibrous and admixture. When the substrate contains fibrous material, the strength of the substrate can be increased as compared with the case where the substrate does not contain fibrous material. Further, as the admixture, it is preferable to use a material having a lighter specific gravity than sand or gravel.

A pattern may be formed on the surface of the substrate. Further, this pattern may be formed by providing unevenness on the surface of the substrate. The surface of the substrate may be colored.

As shown in FIG. 2, the first substrate 10 has a front surface 11, a back surface 12, one end 13, an other end 14 facing the other end 14, another end 15, and another other end 16 facing the other end 15. doing. A first fitting portion (not shown for a specific shape) may be formed at one end 13, and a second fitting portion (not shown for a specific shape) may be formed at the other end 14. May be done. The other end 16 is cut diagonally so that the front surface 11 is longer than the back surface 12. The angle formed by the surface of the surface 11 and the surface of the other end 16 is an acute angle, but may be approximately 45 degrees. The angle formed by the surface of the surface 11 and the surface of another end 15 may be approximately 90 degrees. The angle formed by the surface of the back surface 12 and the surface of another end 15 may be approximately 90 degrees. The angle formed by the surface of the back surface 12 and the surface of the other end 16 is an obtuse angle, but may be approximately 135 degrees. Further, although the front surface 11 may have irregularities, the surface of the front surface 11 and the surface of the back surface 12 are substantially parallel as shown in FIGS. 2 and 3.

As shown in FIG. 2, the second substrate 20 has a front surface 21, a back surface 22, one end 23, an other end 24 facing the other end 24, another end 25, and another other end 26 facing the other end 25. doing. A first fitting portion (not shown for a specific shape) may be formed at one end 23, and a second fitting portion (not shown for a specific shape) may be formed at the other end 24. May be done. The other end 25 may be cut diagonally so that the front surface 21 is longer than the back surface 22. The angle formed by the surface of the surface 21 and the surface of another end 25 is an acute angle, but may be approximately 45 degrees. Further, the angle formed by the surface of the surface 21 and the surface of the other end 26 may be approximately 90 degrees. Further, the angle formed by the surface of the back surface 22 and the surface of the other end 26 may be approximately 90 degrees. The angle formed by the surface of the back surface 22 and the surface of another end 25 is an obtuse angle, but may be approximately 135 degrees. Further, although the front surface 21 may have irregularities, the surface of the front surface 21 and the surface of the back surface 22 are substantially parallel as shown in FIGS. 2 and 3. Further, it is preferable that the sum of the angle formed by the surface of the surface 11 and the surface of the other end 16 and the angle formed by the surface of the surface 21 and the surface of the other end 25 is approximately 90 degrees. When the outer wall near the outer corner of the building is covered with the outer corner material manufactured by the method for manufacturing the outer corner material in the first embodiment, the surface 21 of the outer corner material has an orthogonal relationship with the outer corner material. This is because the surface of the other outer wall materials in the building can be made substantially the same plane as the surface of the other exterior wall materials, and the appearance of the building can be improved.

The manufacturer may prepare a saw, a cutter, or the like that is inclined at an acute angle counterclockwise from the back surface in order to cut out the first substrate 10 and the second substrate 20 from the substrate. When the manufacturer pushes the substrate from the front in the direction away from the body to cut out the first substrate, the cutting starts from the other end 14 and ends at one end 13. Further, when the manufacturer pushes the substrate from the front in the direction away from the body to cut out the second substrate, the cutting starts from the other end 23 and ends at one end 24. This acute angle may be approximately 45 degrees.

The manufacturer may prepare a saw, a cutter, or the like that is inclined at an obtuse angle counterclockwise from the back surface in order to cut out the first substrate 10 and the second substrate 20 from the substrate. When the manufacturer pushes the substrate from the front in the direction away from the body to cut out the first substrate, the cutting starts from one end 13 and ends at the other end 14. Further, when the manufacturer pushes the substrate from the front in the direction away from the body to cut out the second substrate, the cutting starts from one end 24 and ends at the other end 23. This obtuse angle may be approximately 135 degrees.

In order to cut out the first substrate 10 and the second substrate 20 from the substrate almost at once, the manufacturer uses a saw or cutter that is tilted at an acute angle counterclockwise from the back surface and an obtuse angle counterclockwise from the back surface. A saw or cutter tilted toward the surface may be prepared. When the manufacturer pushes the substrate from the front toward the body to cut out the first substrate and the second substrate, the cutting starts from the other end 14 of the first substrate, ends at one end 13 of the first substrate, and ends with the second substrate. It starts cutting at one end 24 and ends at the other end 23 of the second substrate. This acute angle may be approximately 45 degrees. This obtuse angle may be approximately 135 degrees.

After preparing the first substrate 10 and the second substrate 20, the first substrate 10 and the second substrate 20 are adhered to each other (step S20). For example, an adhesive is applied to another other end 16 of the first substrate 10 and another end 25 of the second substrate 20, and the surfaces thereof are overlapped with each other to at least the surface 11 of the first substrate 10 and the second substrate 20. This may be performed by applying a force to the front surface 21 of the first substrate 10 and supporting the back surface 12 of the first substrate 10 and the back surface 22 of the second substrate 20 so as not to shift.

Further, before the adhesive is applied to the other end 16 of the first substrate 10 and the other end 25 of the second substrate 20, the other end 16 of the first substrate 10 and the second substrate 20 A pretreatment such as a primer treatment may be performed on another end 25.

Further, after the adhesive is applied to another other end 16 of the first substrate 10 and another end 25 of the second substrate 20, a high frequency voltage is applied to the adhesive surface by a high frequency adhesive machine to increase the adhesion speed. You may speed it up. In that case, a urethane-based adhesive may be used as the adhesive.

Further, the first substrate 10 and the second substrate 20 may be bonded by natural curing without using a machine such as a high-frequency adhesive machine. In that case, a polyurethane-based adhesive, a urethane-based adhesive, or an epoxy-based adhesive may be applied to the adhesive surface as the adhesive.

FIG. 3 is a diagram showing an example of an intermediate member 30 to which the first substrate 10 and the second substrate 20 are bonded. When the intermediate member 30 is viewed from the other end of the first substrate (reference numeral 14 in FIG. 2), the intermediate member 30 has a substantially L shape.

In order to form the protruding corner material, the second substrate 20 is cut so as to be aligned with the back surface 12 of the first substrate 10 (step S30). For example, a part of the second substrate 20 is cut along the broken line 27 with a saw, a cutter, or the like. The cut portion includes another other end 26.

Hereinafter, a method for manufacturing a corner lumber according to a second embodiment of the present invention will be described with reference to the drawings.

FIG. 4 is an external view showing an example of an intermediate member 40 to which the first substrate 10 and the second substrate 20 are bonded.

In the intermediate member 40, the adhesive 41 comes out from the adhesive surfaces of the first substrate 10 and the second substrate 20 to the surfaces of the first substrate 10 and the second substrate. It is preferable to apply an appropriate amount of the adhesive so that the adhesive does not overflow from the adhesive surfaces of the first substrate 10 and the second substrate 20, but if the amount of the adhesive is less than the appropriate amount, a gap is formed on the adhesive surface and the first substrate 10 and the second substrate 20 are used. The strength of adhering the substrate 20 is reduced. Therefore, the adhesive is applied to the adhesive surface in an amount larger than an appropriate amount, and the intermediate member 40 shown in FIG. 4 can be formed.

In this case, it is preferable to provide a removal step for removing the adhesive 41 on the surface of the intermediate member 40 between steps S20 and S30 or after step S30. This is to improve the appearance of the finished lumber.

Further, when the adhesive comes out from the adhesive surface of the first substrate 10 and the second substrate 20 to the back surface of the first substrate 10 and the second substrate, the back surface of the intermediate member 40 is between steps S20 and S30. It is preferable to provide a removal step for removing the adhesive in. This is because a part of the second substrate 20 is neatly cut by a manufacturing apparatus described later.

FIG. 5 is a diagram for explaining an example of removing the adhesive.

When the manufacturer removes the adhesive 51 on the surface of the intermediate member 50, as shown in FIG. 5, the manufacturer removes a part 17 of the surface of the first substrate 10 and a part 18 of the surface of the second substrate 20. You may. In other words, the L-shaped corner of the intermediate member 50 may be chamfered. This is because it is difficult to remove only the adhesive protruding from the connection portion between the first substrate 10 and the second substrate 20. The L-shaped corner of the intermediate member 50 is made up of a sharp portion 17 of the first substrate 10 and a sharp portion 27 of the second substrate 20, and the adhesive on the surface of the intermediate member 50 is removed cleanly by cutting or the like. In this case, if the cutting is performed as deeply as possible, the tip portions 17 and 27 may be chipped, and the appearance of the projected corner material, which is the final finished product, may be deteriorated. Further, when removing the adhesive 52 on the back surface of the intermediate member 50, the manufacturer does not need to be so careful as to remove the adhesive 51 on the surface of the intermediate member 50.

Therefore, by intentionally chamfering the L-shaped corner of the intermediate member 50 and scraping the sharp portion 17 of the first substrate 10 and the sharp portion 27 of the second substrate 20, damage that deteriorates the appearance does not occur. can do. In the example shown in FIG. 5, the linear distance from the apex of the L-shaped corner of the intermediate member 50 to the boundary between the machined portion and the uncut portion of the first substrate 10 in the sharp portion 17 is 2 mm. It may be ~ 5 mm, and the linear distance from the apex of the L-shaped corner of the intermediate member 50 to the boundary between the machined portion and the uncut portion of the second substrate 20 in the sharp portion 27 is It may be 2 mm to 5 mm, and the linear 55 (actually one surface) is chamfered, but the present invention is not limited to this. The chamfered portion may be composed of a plurality of lines (actually, a plurality of surfaces). The chamfered portion may be formed in an arc shape (actually, a curved surface). Further, the length of the linear 55 may be 2 mm to 7 mm.

When cutting out the second substrate 70 from one substrate, the manufacturer can form another other end 76 by, for example, a circular saw blade inclined at an acute angle counterclockwise from the X direction of the substrate. The second substrate 20 may be cut out from the substrate. This acute angle may be approximately 45 degrees.

When the manufacturer cuts out the second substrate 70 with a circular saw blade tilted approximately 45 degrees counterclockwise from the X direction of the substrate and then cuts out the first substrate 60, the manufacturer may, for example, X of the substrate. Another end 65 is formed by a circular saw blade tilted at an acute angle counterclockwise from the direction, and another end 66 is formed by a circular saw blade tilted at an acute angle counterclockwise from the X direction of the substrate. By doing so, the first substrate 60 may be cut out. This obtuse angle may be approximately 135 degrees. Further, this acute angle may be approximately 45 degrees.

When cutting out the third substrate 80, the manufacturer may form another end 85 by, for example, a circular saw blade inclined at an obtuse angle counterclockwise from the X direction of the substrate, and the third substrate 80 may be cut out. good. This obtuse angle may be approximately 135 degrees.

In the above-mentioned example, the first substrate 60, the second substrate 70, and the third substrate 80 were cut out in this order, but using the same method as in the above-mentioned example, the third substrate 80, the first substrate 60, and the first substrate 80 were cut out. Each of the two substrates 70 may be cut out in this order. Further, the first substrate 60, the second substrate 70, and the third substrate 80 may be cut out in the same manner as in the first embodiment.

After preparing the first substrate 60, the second substrate 70, and the third substrate 80, the first substrate 60 and the second substrate 70 are bonded to each other (step S120). For example, an adhesive is applied to another end 65 of the first substrate 60 and another other end 76 of the second substrate 70, and the surfaces thereof are overlapped with each other to at least the surface 61 of the first substrate 60 and the second substrate 70. It may be performed by applying a force to the front surface 71 of the above and supporting the back surface 62 of the first substrate 60 and the back surface 72 of the second substrate 70 so as not to be displaced.

After adhering the first substrate 60 and the second substrate 70, the first substrate 60 and the third substrate 80 are adhered (step S122). For example, an adhesive is applied to another other end 66 of the first substrate 60 and another end 85 of the third substrate 80, and the surfaces thereof are overlapped with each other so that at least the surface 61 of the first substrate 60 and the third substrate 80 are overlapped. This may be performed by applying a force to the front surface 81 of the first substrate 60 and supporting the back surface 62 of the first substrate 60 and the back surface 82 of the third substrate 80 so as not to be displaced.

Further, before the adhesive is applied to the other end 65 of the first substrate 60 and the other other end 76 of the second substrate 70, the other end 65 of the first substrate 60 and the second substrate 70 are separated.

When each substrate is adhered by a high-frequency adhesive machine, a urethane-based adhesive may be applied to the adhesive surface as an adhesive. For example, by applying a high-frequency voltage to the electrodes 91 and 92 of the high-frequency adhesive machine, adhesion can be performed in a shorter time than in natural curing.

However, the first substrate 60, the second substrate 70, and the third substrate 80 may be adhered by natural curing without using a machine such as a high frequency adhesive machine. In that case, a polyurethane-based adhesive, a urethane-based adhesive, or an epoxy-based adhesive may be applied to the adhesive surface as the adhesive. For natural curing, it is not necessary to equip equipment such as a high frequency welder.

FIG. 8A is a diagram showing an example of an intermediate member 98 to which the first substrate 60, the second substrate 70, and the third substrate 80 are bonded, and FIG. 8B is a diagram showing an example of the intermediate member 98 to which the intermediate member 98 to the third substrate 80 are bonded. It is a figure which shows an example of the intermediate member 99 which cut a part of 80. The intermediate member 98 has a substantially U-shape.

One of the second substrate 70 and the third substrate 80 is cut from the intermediate member 98 so as to be aligned with the back surface 62 of the first substrate 60 to form the intermediate member 99 (step S130). In the example shown in FIG. 8A, a part of the third substrate 80 is cut along the broken line 95 by a saw, a cutter, or the like. The cut portion includes another other end 86.

Next, in order to form the protruding corner material, the other of the second substrate 70 and the third substrate 80 is cut from the intermediate member 99 so as to be aligned with the back surface 62 of the first substrate 60 (step S132). In the example shown in FIG. 8B, a part of the second substrate 70 is cut along the broken line 96 by a saw, a cutter, or the like. The cut portion contains another end 75.

In the manufacturing process of the protruding corner material in the third embodiment, the adhesive may be removed in the same manner as in the manufacturing process of the protruding corner material in the second embodiment described above.

Hereinafter, the manufacturing apparatus according to the fourth embodiment of the present invention will be described with reference to the drawings.

FIG. 9 is a diagram showing an example of a manufacturing apparatus 100 for cutting a part of the second substrate 20 in step S30.

The manufacturing apparatus 100 according to the fourth embodiment of the present invention has a first guide 110 for guiding the first substrate 10 and a second guide 120 for guiding the second substrate 20, and a passage portion 130 for passing the intermediate member 30. The first substrate 10 is pressed against the first guide 110 and the cutting device 140 that cuts a part of the second substrate 20 so as to be aligned with the back surface of the first substrate 10 on the surface whose normal axis is the vertical axis. It is provided with a first feed unit 150 for pressing the second substrate 20 against the second guide 120 and a second feed unit 160 for transporting the second substrate 20.

The first guide 110 has a configuration that reduces friction when the intermediate member 30 moves in the manufacturing apparatus 100. For example, the first guide 110 may be formed by a plurality of rollers.

Similarly, the second guide 120 has a configuration that reduces friction when the intermediate member 30 moves in the manufacturing apparatus 100. For example, the second guide 120 may be formed by a plurality of rollers.

The cutting device 140 may be a saw. When the cutting device 140 is a saw, one that makes a rotary motion is preferable to one that makes a reciprocating motion. This is because it is not necessary to once convert the rotational motion from a power source such as a motor into reciprocating motion.

Further, since the cutting device 140 can cut a part of the second substrate 20 so as to be aligned with the back surface 12 of the first substrate 10 on a surface having a substantially vertical axis as a normal, in other words, a substantially horizontal plane, the following Play the effect of.

For example, when the circular saw rotates vertically like a normal circular saw and cuts a part of the second substrate 20 in the vertical direction, the surface 21 of the second substrate 20 faces upward and the surface 11 of the first substrate 10 Flows sideways. The size of the first substrate is larger than the size of the second substrate, and the weight of each of the first substrates is heavier than that of the second substrate. Due to the weight of the first substrate 10 and the principle of leverage, the first substrate 10 is slightly separated from the cut portion, and the cut portion of the second substrate 20 on the first substrate 10 side is slightly increased to become the first substrate 10. The cutting end of the remaining second substrate 20 is cut deeper by the cutting device 140 than at the beginning of cutting. However, when a part of the second substrate 20 is cut in the lateral direction as in the fourth embodiment, the second substrate is lighter than the first substrate, so that the above-mentioned change is slight.

Further, when a part of the second substrate 20 is cut in the lateral direction, the surface 11 of the first substrate 10 faces upward and flows, so that the manufacturer can view the appearance of the surface 11 of the first substrate 10 having a large area. You can work while checking, and you can sort out defective products.

Further, when a part of the second substrate 20 is cut in the lateral direction, the surface 11 of the first substrate 10 flows upward, so that the manufacturer can lie down and flow the surface 11 of the first substrate 10. It is easier to work than when it comes. For example, when the manufacturer accumulates the cut corners, the corners with the surface 11 of the first substrate 10 facing upward may be picked up and moved. However, when cutting a part of the second substrate 20 in the lateral direction, it is necessary to pick up and move the protruding corner material whose surface is facing laterally. For the accuracy of the work, you will have to hold the protruding corner material with both hands, but to receive the protruding corner material with the surface facing sideways, one shoulder will be lowered and the manufacturer will be unnatural. The condition has to be repeated, which puts a burden on the manufacturer.

Hereinafter, a case where the cutting device 140 is a circular saw will be described. The cutting device 140 is rotated by the motor 141. The manufacturing apparatus 100 may include a mechanism capable of changing the position of the cutting device 140. For example, the motor 141 can be moved up and down along the rail 142. Further, the rail 142 is attached to the pedestal 143. The pedestal 143 can be moved away from or closer to the first guide 110 or the second guide 120 by the mechanism 144.

The first feed unit 150 presses the first substrate 10 against the first guide 110 and conveys the intermediate member 30. The first feed unit 150 may have a ring-shaped first belt 151 and a first motor 152. As the first motor 152 rotates, the first belt 151 rotates and the intermediate member 30 is conveyed.

Further, the second feed unit 160 presses the second substrate 20 against the second guide 120 and conveys the intermediate member 30. The second feed unit 160 may have a ring-shaped second belt 161 and a second motor 162. As the second motor 162 rotates, the second belt 161 rotates and the intermediate member 30 is conveyed. Since the second feed portion 160 presses the second substrate 20 against the second guide 120, the cut surface of the second substrate 20 on the first substrate 10 side hardly fluctuates and is adhered to the first substrate 10. The cut surface of the second substrate 20 is cut neatly and straightly.

FIG. 10 is a schematic view showing an example of the positions where the first belt 151 and the second belt 161 are located in the manufacturing apparatus 100. In FIG. 10, the first belt 151 and the second belt 161 are described only for the portion where the intermediate member 30 is pressed against the first guide 110 and the second guide 120, and the motor and the like are described. Is omitted.

The intermediate member 30 is conveyed from the left side to the right side in FIG. The intermediate member 30 is sandwiched between the first belt 151 and the first guide 110, and is further sandwiched between the second belt 161 and the second guide 120 and moves. When the intermediate member 30 is transported from the left side to the right side in FIG. 10, the cutting device 140 rotates counterclockwise.

In the vicinity of the cutting device 140, the first guide 110 has a notch portion 111. Similarly, in the vicinity of the cutting device 140, the second guide 120 has a notch portion 121. When the cutting device 140 cuts a part of the second substrate 20 on the back surface 12 of the first substrate 10, the first guide 110 and the second guide 120 guide the intermediate member 30 in the vicinity of the cutting device 140. If this is the case, the cutting device 140 will cut a part of the second substrate 20 with an error of 0, which will lead to blade spillage of the cutting device 140. Therefore, notch portions 111 and 121 are provided in the vicinity of the cutting device 140.

The cutout portion 111 may be provided over the entire range of the first guide 110. Similarly, the notch portion 121 may be provided over the entire range of the second guide 120. At the corners between the back surface 12 of the first substrate 10 and the back surface 22 of the second substrate 20, there is a possibility of poor removal of the adhesive or excessive cutting when removing the adhered adhesive, and the corners This is because, if the adhesive leaking from the adhesive is not removed, it is not preferable to transport the intermediate member with the corner as a reference.

Further, in order to cut a part of the second substrate 20 on the back surface 12 of the first substrate 10, the intermediate member 30 is used in the rotation axis direction of the cutting device 140, the rotation axis direction of the cutting device 140, and the rotation axis direction of the cutting device 140. It is necessary to hold down the intermediate member 30 so as not to move in the direction 180 perpendicular to the traveling direction of the intermediate member 30. Therefore, the first feed unit 150 presses the surface 11 of the first substrate 10 against the first guide 110 with the first belt 151 so as not to shake in the rotation axis direction of the cutting device 140. Further, since the main vibration source that vibrates the intermediate member 30 in the vertical direction is the cutting device 140, the first belt 151 may push the first guide 110 near the notch portion 111 via the intermediate member 30. preferable. Further, the length of the portion of the first belt 151 that presses the intermediate member 30 may be longer than the diameter of the circular saw.

Similarly, the second feed unit 160 presses the surface 21 of the second substrate 20 against the second guide 120 with the second belt 161 so as not to move in the direction 180. Further, since the main vibration source that vibrates the intermediate member 30 in the direction 180 is the cutting device 140, the second belt 161 may push the second guide 120 near the notch portion 121 via the intermediate member 30. preferable. Further, the length of the portion of the second belt 161 pressing the intermediate member 30 may be longer than the diameter of the circular saw. Further, the length of the portion of the first belt 151 that presses the intermediate member 30 may be substantially the same as the length of the portion of the second belt 161 that presses the intermediate member 30.

Further, the second belt 161 is arranged below the cutting device 140. In other words, the second belt 161 is arranged at a position far from the first substrate 10 via the cutting device 140 in the second guide 120. Therefore, even if the second belt 161 presses the second substrate 20 against the second guide 120 very strongly, the surface of the protruding corner material to be a product is not damaged.

The cutting device 140 may be covered with a metal cover. This is to prevent the manufacturer from injuring the body with the cutting device 140. Further, a suction duct for sucking shavings of a substrate or the like may be connected to the cover. This is to prevent shavings and the like from accumulating in the cover and deteriorating the rotation of the cutting device 140. When the cover is provided with a suction duct, it is preferable that the cover is further provided with an intake duct. This is because the manufacturer may injure the body by the cutting device 140 simply by making a hole for intake in the cover. Further, by providing the intake duct, the suction force can be increased.

The operation of the manufacturing apparatus 100 has been described using the intermediate member 30, but instead of the intermediate member 30, the member from which the adhesive 41 has been removed from the intermediate member 40 as described above, and the adhesives at the tips 17 and 27 from the intermediate member 50. Even if a member or the like from which 51 and 52 have been removed is used, the protruding corner material can be manufactured.

Further, a part of the second substrate 70 or the third substrate 80 is formed by flowing the intermediate member 98 or a member from which at least one of the corners on the front surface and the corner on the back surface is removed from the intermediate member 100. It may be disconnected. Similarly, the intermediate member 99 or a member from which at least one of the front corners and the back surface corners from which the adhesive has been removed is flowed, and the second feed unit 160 guides the third substrate 80 to the second guide. A part of the third substrate 80 may be cut by pressing against 120. Further, when a part of the third substrate 80 is cut first from the intermediate member 98, a part of the second substrate 70 may be cut by the manufacturing apparatus 100 after that.

The manufacturing apparatus 100 includes a third guide that guides the third substrate 80, a third feed portion that presses and conveys the third substrate 80 against the third guide, and the third substrate 80 so as to align with the back surface of the first substrate 60. A second cutting device for cutting a part may be further provided. Further, the third guide, the third feed portion and the second cutting device may be arranged on substantially opposite sides of the second guide 120, the second feeding portion 160 and the cutting device 140 via the passage portion 130. As described above, when the manufacturing apparatus 100 further includes the third guide, the third feed portion, and the second cutting device, only a part of the second substrate 70 and a part of the second substrate 70 can be passed through the intermediate member 98 once. A part of the third substrate 80 can be cut. As described above, even if the manufacturing apparatus 100 further includes the third guide, the third feed portion, and the second cutting device, at least one adhesive protruding from the front corner and the back corner of the intermediate member 98. Needless to say, a part of the second substrate 70 and a part of the third substrate 80 can be cut from the member from which the above-mentioned material has been removed.

When the manufacturing apparatus 100 includes a second cutting device, the first guide has a third notch portion similar to the notch portion 111 in the vicinity of the second cutting device in order to arrange the second cutting device. It is preferable that the third guide has a fourth notched portion similar to the notched portion 121 of the second guide in the vicinity of the second cutting device. This is to prevent the blade of the second cutting device from spilling.

Further, when the manufacturing apparatus 100 includes the second cutting device, it is preferable that the third feeding portion is arranged at the lower part of the second cutting device. Therefore, since the third feed unit presses the third substrate against the third guide at the lower part of the second cutting device, the vibration generated by the cutting device can be efficiently absorbed.

The second cutting device may be a circular saw. This is because the mechanism can be simplified as compared with a reciprocating saw.
