Description

本発明は、出隅材製造方法に関する。The present invention relates to a method for manufacturing a corner material.

基板の一方の端部を球面状または多面状に切削することにより、出隅材を製造することが知られている（特許文献１）。 It is known to manufacture corner pieces by cutting one end of a substrate into a spherical or multifaceted shape (Patent Document 1).

特開２００９－５７８０７号公報JP 2009-57807 A

特許文献１に示されている方法では、基板の一方の端部を切削し、コーナが形成されるため、出隅材を製造するのに時間が掛かるという問題がある。 The method shown in Patent Document 1 has the problem that it takes time to manufacture the corner material because one end of the board is cut to form the corner.

さらに、特許文献１に示されている方法では、切削により出隅材の角部が形成されるため、その角部が基板の外面の模様を反映することがないという問題がある。 Furthermore, in the method shown in Patent Document 1, the corners of the corner material are formed by cutting, which creates the problem that the corners do not reflect the pattern on the outer surface of the substrate.

本発明の出隅材製造方法は、表面と、裏面と、一端と、それに対向する他端と、別の一端と、それに対向する別の他端とを有し、前記一端には第１嵌合部が形成され、前記他端には第２嵌合部が形成され、前記別の他端は、前記表面が前記裏面よりも長くなるように斜めに切断されている第１基板を用意する工程と、表面と、裏面と、一端と、それに対向する他端と、別の一端と、それに対向する別の他端とを有し、前記一端には第１嵌合部が形成され、前記他端には第２嵌合部が形成され、前記別の一端は、前記表面が前記裏面よりも長くなるように斜めに切断されている第２基板を用意する工程と、前記第１基板の前記別の他端および前記第２基板の前記別の一端の少なくとも一方に接着剤を塗布し、前記第１基板の前記別の他端と前記第２基板の前記別の一端とを合わせて接着する接着工程と、前記第１基板の前記裏面にそろうように前記第２基板を切断する切断工程とを包含する。本発明の別の出隅材製造方法は、表面と、裏面と、一端と、それに対向する他端と、別の一端と、それに対向する別の他端とを有し、前記表面の面と前記別の一端の面がなす角が鋭角であり、前記表面の面と前記別の他端の面がなす角が鋭角である第１基板を用意する工程と、表面と、裏面と、一端と、それに対向する他端と、別の一端と、それに対向する別の他端とを有し、前記表面の面と前記別の他端の面がなす角が鋭角である第２基板を用意する工程と、表面と、裏面と、一端と、それに対向する他端と、別の一端と、それに対向する別の他端とを有し、前記表面の面と前記別の一端の面がなす角が鋭角である第３基板を用意する工程と、前記第１基板の前記別の一端および前記第２基板の前記別の他端の少なくとも一方に接着剤を塗布し、前記第１基板の前記別の一端と前記第２基板の前記別の他端とを合わせて接着する接着工程と、前記第１基板の前記別の他端および前記第３基板の前記別の一端の少なくとも一方に接着剤を塗布し、前記第１基板の前記別の他端と前記第３基板の前記別の一端とを合わせて接着する接着工程と、前記第１基板の前記裏面にそろうように前記第２基板および前記第３基板のうちの少なくとも一方を切断する切断工程とを包含する。 The method for manufacturing a corner material of the present invention includes the steps of: preparing a first substrate having a surface, a back surface, one end, an opposing other end, another end, and another opposing other end, with a first fitting portion formed at the one end and a second fitting portion formed at the other end, the surface being cut at an angle so that the surface is longer than the back surface; preparing a second substrate having a surface, a back surface, one end, an opposing other end, and another opposing other end, with a first fitting portion formed at the one end and a second fitting portion formed at the other end, the surface being cut at an angle so that the surface is longer than the back surface; applying adhesive to at least one of the other end of the first substrate and the other end of the second substrate, and bonding the other end of the first substrate and the other end of the second substrate together; and cutting the second substrate so that the substrate is aligned with the back surface of the first substrate. Another method for manufacturing a corner member of the present invention includes the steps of: preparing a first substrate having a front surface, a back surface, one end, an opposing other end, another end, and another opposing other end, wherein the angle formed between the front surface and the face of the other end is an acute angle; preparing a second substrate having a front surface, a back surface, one end, an opposing other end, another end, and another opposing other end, wherein the angle formed between the front surface and the face of the other end is an acute angle; The method includes a step of preparing a third substrate having an acute angle at its end face, a bonding step of applying adhesive to at least one of the other end of the first substrate and the other end of the second substrate, and bonding the other end of the first substrate and the other end of the second substrate together, a bonding step of applying adhesive to at least one of the other end of the first substrate and the other end of the third substrate, and bonding the other end of the first substrate and the other end of the third substrate together, and a cutting step of cutting at least one of the second substrate and the third substrate so that it is flush with the rear surface of the first substrate.

本発明のある実施形態における出隅材製造方法は、前記第１基板の前記別の他端と、前記第２基板の前記別の一端との接着部から外に漏れ出した接着剤を除去する除去工程を包含していてもよい。本発明の別の実施形態における出隅材製造方法は、前記第１基板と前記第２基板の接着部から外に漏れ出した接着剤を除去し、前記第１基板と前記第３基板の接着部から外に漏れ出した接着剤を除去する除去工程とを包含してもよい。 The method for manufacturing a corner member in one embodiment of the present invention may include a removal step of removing adhesive that has leaked out from the adhesive joint between the other end of the first substrate and the other end of the second substrate. The method for manufacturing a corner member in another embodiment of the present invention may include a removal step of removing adhesive that has leaked out from the adhesive joint between the first substrate and the second substrate, and removing adhesive that has leaked out from the adhesive joint between the first substrate and the third substrate.

本発明のある実施形態における出隅材製造方法は、前記除去工程において、前記接着剤を除去する際に、前記第１基板の一部と前記第２基板の一部を含めて除去する除去工程を包含してもよい。本発明の別の実施形態における出隅材製造方法は、前記除去工程において、前記接着剤を除去する際に、前記第１基板の一部と前記第２基板の一部を含めて除去し、前記第１基板の一部と前記第３基板の一部を含めて除去する除去工程を包含してもよい。 In one embodiment of the present invention, the method for manufacturing a corner member may include a removal step in which, when removing the adhesive, a part of the first substrate and a part of the second substrate are also removed. In another embodiment of the present invention, the method for manufacturing a corner member may include a removal step in which, when removing the adhesive, a part of the first substrate and a part of the second substrate are also removed, and a part of the first substrate and a part of the third substrate are also removed.

本発明のある実施形態における出隅材製造方法は、前記除去工程の後に、第１基板および第２基板の除去された部分を着色する着色工程を包含してもよい。本発明の別の実施形態における出隅材製造方法は、前記除去工程の後に、前記第１基板および前記第２基板の除去された部分と、前記第１基板および前記第３基板の除去された部分を着色する着色工程を包含してもよい。 In one embodiment of the present invention, the method for manufacturing a corner member may include a coloring step of coloring the removed portions of the first substrate and the second substrate after the removal step. In another embodiment of the present invention, the method for manufacturing a corner member may include a coloring step of coloring the removed portions of the first substrate and the second substrate and the removed portions of the first substrate and the third substrate after the removal step.

本発明のある実施形態における出隅材製造方法では、前記着色する色が、前記第１基板の前記表面の色と略同じであってもよい。本発明の別の実施形態における出隅材製造方法は、前記着色する色が、前記第１基板の前記表面の色と略同じであってもよい。 In one embodiment of the present invention, the method for manufacturing a corner member may be such that the color to be applied is substantially the same as the color of the surface of the first substrate. In another embodiment of the present invention, the method for manufacturing a corner member may be such that the color to be applied is substantially the same as the color of the surface of the first substrate.

本発明のある実施形態における出隅材製造方法では、前記切断工程において、前記接着された前記第１基板および前記第２基板を搬送し、略水平面内で切断器により前記第２基板の一部を切断してもよい。本発明の別の実施形態における出隅材製造方法は、前記切断工程において、前記接着された前記第１基板、前記第２基板および第３基板を搬送し、略水平面内で切断器により、前記第２基板の一部および前記第３基板の一部の少なくとも一方を切断してもよい。 In one embodiment of the present invention, the method for manufacturing a corner member may include, in the cutting step, transporting the bonded first and second substrates and cutting a portion of the second substrate with a cutter in a substantially horizontal plane. In another embodiment of the present invention, the method for manufacturing a corner member may include, in the cutting step, transporting the bonded first, second and third substrates and cutting at least one of the portion of the second substrate and the portion of the third substrate with a cutter in a substantially horizontal plane.

本発明の製造装置は、第１基板および第２基板を有する中間部材から前記第２基板の一部を切断する製造装置であって、前記第１基板をガイドする第１ガイドと、前記第２基板をガイドする第２ガイドとを有し、前記中間部材を通過させる通路と、鉛直方向を法線とする面で、前記第１基板の裏面にそろうように前記第２基板の一部を切断する切断器と、前記第１ガイドに前記第１基板を押しつけ、搬送する第１送り部と、前記第２ガイドに前記第２基板を押しつけ、搬送する第２送り部とを備えている。本発明の別の製造装置は、第１基板、第２基板および第３基板を有する中間部材から前記第２基板および前記第３基板の一部を切断する製造装置であって、前記第１基板をガイドする第１ガイドと、前記第２基板をガイドする第２ガイドと、前記第３基板をガイドする第３ガイドとを有し、前記中間部材を通過させる通路と、鉛直方向を法線とする面で、前記第１基板の裏面にそろうように前記第２基板の一部を切断する第１切断器と、鉛直方向を法線とする面で、前記第１基板の裏面にそろうように前記第３基板の一部を切断する第２切断器と、前記第１ガイドに前記第１基板を押しつけ、搬送する第１送り部と、前記第２ガイドに前記第２基板を押しつけ、搬送する第２送り部と、前記第３ガイドに前記第３基板を押しつけ、搬送する第３送り部とを備えている。 The manufacturing apparatus of the present invention is a manufacturing apparatus that cuts a portion of a second substrate from an intermediate member having a first substrate and a second substrate, and has a first guide that guides the first substrate and a second guide that guides the second substrate, a passage through which the intermediate member passes, a cutter that cuts a portion of the second substrate in a plane normal to the vertical direction so as to align with the rear surface of the first substrate, a first feed section that presses the first substrate against the first guide and transports it, and a second feed section that presses the second substrate against the second guide and transports it. Another manufacturing device of the present invention is a manufacturing device that cuts a portion of the second substrate and the third substrate from an intermediate member having a first substrate, a second substrate, and a third substrate, and includes a first guide that guides the first substrate, a second guide that guides the second substrate, and a third guide that guides the third substrate, a passage through which the intermediate member passes, a first cutter that cuts a portion of the second substrate so as to align with the rear surface of the first substrate in a plane having a normal line in the vertical direction, a second cutter that cuts a portion of the third substrate so as to align with the rear surface of the first substrate in a plane having a normal line in the vertical direction, a first feed section that presses the first substrate against the first guide and transports it, a second feed section that presses the second substrate against the second guide and transports it, and a third feed section that presses the third substrate against the third guide and transports it.

本発明のある実施形態における製造装置では、前記切断器を配置するために、前記第１ガイドが第１切り欠け部を有し、前記第２ガイドが第２切り欠け部を有していてもよい。本発明の別の実施形態における製造装置は、前記第１切断器を配置するために、前記第２ガイド付近の前記第１ガイドが第１切り欠け部を有し、前記第２ガイドが第２切り欠け部を有し、さらに、前記第２切断器を配置するために、前記第３ガイド付近の前記第１ガイドが第３切り欠け部を有し、前記第３ガイドが第４切り欠け部を有していてもよい。 In one embodiment of the present invention, the manufacturing device may have a first cutout portion on the first guide and a second cutout portion on the second guide for positioning the cutter. In another embodiment of the present invention, the manufacturing device may have a first cutout portion on the first guide near the second guide and a second cutout portion on the second guide for positioning the first cutter, and further, a third cutout portion on the first guide near the third guide and a fourth cutout portion on the third guide for positioning the second cutter.

本発明のある実施形態における製造装置では、前記第２送り部が前記切断器の下部に配置されていてもよい。本発明の別の実施形態における製造装置は、前記第２送り部が前記第１切断器の下部に配置され、前記第３送り部が前記第２切断器の下部に配置されていてもよい。 In one embodiment of the present invention, the manufacturing device may have the second feed section disposed below the cutter. In another embodiment of the present invention, the manufacturing device may have the second feed section disposed below the first cutter, and the third feed section disposed below the second cutter.

本発明のある実施形態における製造装置では、前記切断器が丸鋸であってもよい。本発明の別の実施形態における製造装置は、前記第１および第２切断器が丸鋸であってもよい。 In one embodiment of the manufacturing device of the present invention, the cutting tool may be a circular saw. In another embodiment of the manufacturing device of the present invention, the first and second cutting tools may be circular saws.

本発明の出隅材製造方法は、第１基板の裏面にそろうように第２基板を切断する切断工程を包含している。このため、本発明の出隅材製造方法で製造された出隅材は板状となり、Ｌ型の出隅材よりも梱包がしやすい。また、本発明の出隅材製造方法で製造された出隅材は板状となるため、Ｌ型の出隅材に比べて、箱詰めした場合デットスペースが生じにくい。本発明の別の出隅材製造方法では、第１基板の裏面にそろうように第２基板および第３基板が切断され得る。このため、本発明の別の出隅材製造方法で製造された出隅材は板状となり、コの字型の出隅材よりも梱包がしやすい。また、本発明の出隅材製造方法で製造された出隅材は板状となるため、コの字型の出隅材に比べて、箱詰めした場合デットスペースが生じにくい。 The method for manufacturing an external corner material of the present invention includes a cutting step of cutting the second substrate so that it is aligned with the back surface of the first substrate. Therefore, the external corner material manufactured by the method for manufacturing an external corner material of the present invention is in a plate shape, and is easier to pack than an L-shaped external corner material. In addition, since the external corner material manufactured by the method for manufacturing an external corner material of the present invention is in a plate shape, it is less likely to cause dead space when packed in a box compared to an L-shaped external corner material. In another method for manufacturing an external corner material of the present invention, the second substrate and the third substrate can be cut so that they are aligned with the back surface of the first substrate. Therefore, the external corner material manufactured by the method for manufacturing an external corner material of the present invention is in a plate shape, and is easier to pack than a U-shaped external corner material. In addition, since the external corner material manufactured by the method for manufacturing an external corner material of the present invention is in a plate shape, it is less likely to cause dead space when packed in a box compared to an U-shaped external corner material.

本発明の出隅材製造方法は、第１基板の別の他端と第２基板の別の一端とを合わせて接着する接着工程を包含している。このため、本発明の出隅材製造方法で製造された出隅材は、特許文献１の出隅材製造方法のように外観を成形する必要がないため、特許文献１の出隅材製造方法に比べて、安価に製造することが可能である。本発明の別の出隅材製造方法についても同様である。 The method for manufacturing an external corner material of the present invention includes a bonding step in which another end of the first substrate and another end of the second substrate are bonded together. Therefore, the external corner material manufactured by the method for manufacturing an external corner material of the present invention does not need to be shaped as in the method for manufacturing an external corner material of Patent Document 1, and therefore can be manufactured more inexpensively than the method for manufacturing an external corner material of Patent Document 1. The same is true for the other method for manufacturing an external corner material of the present invention.

本発明のある実施形態における出隅材製造方法は、第１基板の別の他端と、第２基板の別の一端との接着部から外に漏れ出した接着剤を除去する除去工程を包含している。このため、この出隅材製造方法で製造された出隅材は、接着剤が足りずに接着不良となることがない。本発明の別の実施形態における出隅材製造方法についても同様である。 The method for manufacturing an outboard corner member in one embodiment of the present invention includes a removal step for removing adhesive that has leaked out from the adhesive joint between the other end of the first substrate and the other end of the second substrate. Therefore, the outboard corner member manufactured by this method for manufacturing an outboard corner member does not suffer from poor adhesion due to insufficient adhesive. The same is true for the method for manufacturing an outboard corner member in another embodiment of the present invention.

本発明のある実施形態における出隅材製造方法は、除去工程において、接着剤を除去する際に、第１基板の一部と第２基板の一部を含めて除去する。このため、予め破損の原因となる出隅材の隅を取り除くことができる。また、接着剤を除去する際に、出隅材の隅を傷つけないように作業する必要がないため、この出隅材製造方法は、接着剤だけを除去する作業に比べて、接着剤を除去するスピードを上げることができる。本発明の別の実施形態における出隅材製造方法についても同様である。 In one embodiment of the present invention, the method for manufacturing an outboard corner member removes the adhesive during the removal process, along with a portion of the first substrate and a portion of the second substrate. This makes it possible to remove the corners of the outboard corner member, which could cause damage, in advance. In addition, since there is no need to take care not to damage the corners of the outboard corner member when removing the adhesive, this method for manufacturing an outboard corner member can remove the adhesive faster than a process for removing only the adhesive. The same applies to the method for manufacturing an outboard corner member in another embodiment of the present invention.

本発明のある実施形態における出隅材製造方法は、接着剤並びに第１基板の一部および第２基板を除去する除去工程の後に、除去された第１基板の一部と第２基板の一部を着色する着色工程を包含する。このため、看者に対して第１基板および第２基板の削られた部分に違和感を感じさせないようにすることができる。本発明の別の実施形態における出隅材製造方法についても同様である。 The method for manufacturing a corner member in one embodiment of the present invention includes a coloring step of coloring the removed parts of the first substrate and the second substrate after the removal step of removing the adhesive and a part of the first substrate and the second substrate. This makes it possible to prevent the viewer from feeling uncomfortable about the parts that have been cut off from the first substrate and the second substrate. The same applies to the method for manufacturing a corner member in another embodiment of the present invention.

本発明のある実施形態における出隅材製造方法は、接着剤並びに第１基板の一部および第２基板を除去する除去工程の後に、第１基板および第２基板の除去された部分を、第１基板および第２基板と略同じ色で着色する着色工程を包含する。このため、第１基板および第２基板の削られた部分が、第１基板および第２基板の表面と同じに見え、出隅材の商品価値があがる。本発明の別の実施形態における出隅材製造方法についても同様である。 The method for manufacturing a corner member in one embodiment of the present invention includes, after a removal step in which the adhesive and a portion of the first substrate and the second substrate are removed, a coloring step in which the removed portions of the first substrate and the second substrate are colored in substantially the same color as the first substrate and the second substrate. As a result, 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, increasing the commercial value of the corner member. The same applies to a method for manufacturing a corner member in another embodiment of the present invention.

本発明のある実施形態における出隅材製造方法では、切断工程において、接着された第１基板および第２基板が搬送され、略水平面内で切断器により第２基板の一部が切断される。 In one embodiment of the present invention, in the cutting process of the method for manufacturing a corner material, the bonded first and second substrates are transported and a cutter cuts a portion of the second substrate in a substantially horizontal plane.

仮に、縦方向で第２基板の一部を切断すれば、第２基板の表面が上向きとなり、第１基板の表面が横向きとなり流れ、第１基板の自重と梃子の原理によって切断される部分が僅かに増えて、第１基板に残る第２基板の切断部分が切り始めよりも切り終わりの方が切断器により深く切られる。しかし、横方向で第２基板の一部を切断すると、第１基板と接着されている第２基板の切断面は綺麗にまっすぐ切断される。 If part of the second substrate is cut vertically, the surface of the second substrate will face upwards and the surface of the first substrate will face horizontally and flow, and the portion cut off will increase slightly due to the weight of the first substrate and the principle of leverage, and the cut portion of the second substrate remaining on the first substrate will be cut deeper by the cutter at the end of the cut than at the beginning of the cut. However, if part of the second substrate is cut horizontally, the cut surface of the second substrate that is attached to the first substrate will be cut cleanly and straight.

また、横方向で第２基板の一部を切断する場合、第１基板の表面が上向きになり流れてくるため、製造者は、面積の広い第１基板の外観をチェックしながら作業をすることができ、不良品を選別することができる。 In addition, when cutting a portion of the second substrate horizontally, the surface of the first substrate flows upwards, allowing the manufacturer to work while checking the appearance of the larger first substrate and to sort out defective products.

また、横方向で第２基板の一部を切断する場合、第１基板の表面が上向きになり流れてくるため、製造者は、第１基板の表面が横になり流れてくる場合に比べて作業がしやすい。例えば、製造者が切断された出隅材を集積する場合、表面が上を向いている出隅材を手に取り移動させればよい。本発明の別の実施形態における出隅材製造方法についても同様である。 In addition, when cutting a portion of the second substrate horizontally, the surface of the first substrate faces upward as it flows, making it easier for the manufacturer to work than if the surface of the first substrate were to flow horizontally. For example, when the manufacturer is stacking the cut corner pieces, he or she can simply pick up the corner pieces with their surfaces facing upward and move them. The same applies to the method of manufacturing corner pieces in another embodiment of the present invention.

本発明の製造装置は、鉛直方向を法線とする面で、第１基板の裏面にそろうように第２基板の一部を切断する。 The manufacturing device of the present invention cuts a portion of the second substrate in a plane normal to the vertical direction so that it is aligned with the back surface of the first substrate.

仮に、縦方向で第２基板の一部を切断する場合、第２基板の表面が上向きとなり、第１基板の表面が横向きとなり流れ、第１基板の自重と梃子の原理によって切断する部分が僅かに増えて、第１基板に残る第２基板の切断部分が切り始めよりも切り終わりの方が切断器により深く切られる。しかし、横方向で第２基板の一部を切断すると、第１基板と接着されている第２基板の切断面は綺麗にまっすぐ切断される。 If, for example, part of the second substrate is cut vertically, the surface of the second substrate faces upwards and the surface of the first substrate faces horizontally and flows, and the portion to be cut increases slightly due to the weight of the first substrate and the principle of leverage, so that the cut portion of the second substrate remaining on the first substrate is cut deeper by the cutter at the end of the cut than at the beginning of the cut. However, if part of the second substrate is cut horizontally, the cut surface of the second substrate that is attached to the first substrate is cut cleanly and straight.

また、横方向で第２基板の一部を切断する場合、第１基板の表面が上向きとなり流れてくるため、製造者は、面積の広い第１基板の表面の外観をチェックしながら作業をすることができ、不良品を選別することができる。 In addition, when cutting a portion of the second substrate horizontally, the surface of the first substrate flows upwards, allowing the manufacturer to work while checking the appearance of the surface of the larger first substrate, and thus enabling them to select defective products.

また、横方向で第２基板の一部を切断する場合、第１基板の表面が上向きになり流れてくるため、製造者は、第１基板の表面が横向きになり流れてくる場合に比べて作業がしやすい。例えば、製造者が切断された出隅材を集積する場合、表面が上を向いている出隅材を手に取り移動させればよい。 In addition, when cutting a portion of the second board horizontally, the surface of the first board faces upward as it flows, making it easier for the manufacturer to work than if the surface of the first board were to flow sideways. For example, when the manufacturer stacks the cut corner pieces, he or she can simply pick up the corner pieces with their surfaces facing upward and move them.

切断器が第１基板の裏面の面にて、第２基板の一部を切断する場合、切断器付近において、第１ガイドおよび第２ガイドが中間部材をガイドしていると、誤差０で切断器が第２基板の一部を切断することとなり、切断器の刃こぼれにつながる。しかし、本発明のある実施形態における製造装置は、切断器を配置するために、第１ガイドが第１切り欠け部を有し、第２ガイドが第２切り欠け部を有する。このため、この製造装置では、切断器がガイドに当接して刃こぼれすることがない。本発明の別の製造装置についても同様である。 When the cutter cuts a portion of the second substrate on the rear surface of the first substrate, if the first guide and the second guide are guiding the intermediate member near the cutter, the cutter will cut a portion of the second substrate with zero error, which could lead to chipping of the cutter blade. However, in one embodiment of the present invention, the manufacturing device has a first notch in the first guide and a second notch in the second guide in order to position the cutter. Therefore, in this manufacturing device, the cutter will not come into contact with the guide and chip. The same is true for other manufacturing devices of the present invention.

本発明のある実施形態における製造装置では、第２送り部が切断器の下部に配置されている。このため、第２基板に強い力を加えても、製品となる出隅材の表面を傷つけてしまうことはない。また、第２送り部が切断器の下部で第２基板を第２ガイドに押しつけるため、切断器が発生する振動を効率よく吸収することができる。本発明の別の実施形態における製造装置についても同様である。 In one embodiment of the manufacturing device of the present invention, the second feed section is located below the cutter. Therefore, even if a strong force is applied to the second substrate, the surface of the corner material that will become the product will not be damaged. In addition, because the second feed section presses the second substrate against the second guide below the cutter, vibrations generated by the cutter can be absorbed efficiently. The same is true for the manufacturing device in another embodiment of the present invention.

本発明のある実施形態における製造装置では、切断器が丸鋸である。このため、この製造装置は、往復運動する鋸に比べで、機構を簡単にすることができる。本発明の別の実施形態における製造装置についても同様である。 In one embodiment of the manufacturing device of the present invention, the cutter is a circular saw. This allows the manufacturing device to have a simpler mechanism than a reciprocating saw. The same is true for the manufacturing device in another embodiment of the present invention.

以下に、図面を参照しながら本発明の第１実施形態における出隅材の製造方法について説明する。 The manufacturing method for the corner material in the first embodiment of the present invention will be described below with reference to the drawings.

図１は、本発明の第１実施形態における出隅材の製造方法を示す流れ図である。また、図２は、第１基板１０および第２基板２０の一例を示す外観図である。 Figure 1 is a flow diagram showing a method for manufacturing a corner member in a first embodiment of the present invention. Also, Figure 2 is an external view showing an example of a first substrate 10 and a second substrate 20.

製造者は、図２に示すような第１基板１０と第２基板２０を用意する（ステップＳ１０）。第１基板１０と第２基板２０は、１枚の基板から切り出されてもよい。その基板は、表面１１、２１と、裏面１２、２２と、一端１３、２３と、その一端１３、２３に対向する他端１４、２４と、別の一端１５と、その別の一端１５に対向する別の他端２６とを有している。なお、別の他端１６と別の一端２５にて挟まれていた部分は、第１基板１０と第２基板２０を切り出す際に切り落とされた部分である。 The manufacturer prepares a first substrate 10 and a second substrate 20 as shown in FIG. 2 (step S10). The first substrate 10 and the second substrate 20 may be cut out from a single substrate. The substrate has a front surface 11, 21, a back surface 12, 22, one end 13, 23, another end 14, 24 opposite the one end 13, 23, another end 15, and another end 26 opposite the other end 15. The portion sandwiched between the other end 16 and the other end 25 is the portion that was cut off when the first substrate 10 and the second substrate 20 were cut out.

基板同士を接続するために、基板の一端１３、２３に、第１嵌合部が形成されていてもよい。また、基板同士を接続するために、基板の他端１４、２４に、第２嵌合部が形成されていてもよい。その場合、一方の基板の第１嵌合部が他の基板の第２嵌合部と嵌合することができる。 A first mating portion may be formed at one end 13, 23 of the substrate to connect the substrates together. A second mating portion may be formed at the other end 14, 24 of the substrate to connect the substrates together. In this case, the first mating portion of one substrate can be mated with the second mating portion of the other substrate.

嵌合部の形状として、合いじゃくりや、本実が用いられてもよい。例えば、基板の一端付近において、基板の表面が基板の裏面より長くなり、基板の他端付近において、基板の表面が基板の裏面より短くなってもよい。また、基板の一端に凸部が設けられ、基板の他端に凹部が設けられてもよい。 The shape of the mating portion may be a mating shape or a square shape. 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. Also, 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.

基板の主な材質は、セメント質材であってもよい。さらに、基板は、繊維質および混和材の少なくとも１つを含んでいてもよい。基板が繊維質を含んでいる場合、繊維質を含んでいないものに比べ基板の強度を高めることができる。また、混和材としては、砂や砂利よりも比重が軽いものが用いられることが好ましい。 The main material of the substrate may be a cementitious material. Furthermore, the substrate may contain at least one of a fiber material and a mineral admixture. When the substrate contains fiber, the strength of the substrate can be increased compared to a substrate that does not contain fiber. Furthermore, it is preferable to use a mineral admixture that has a lower specific gravity than sand or gravel.

基板の表面には、模様が形成されていてもよい。また、この模様は、基板の表面に凹凸を設けることにより、形成されてもよい。基板の表面は、着色されていてもよい。 A pattern may be formed on the surface of the substrate. This pattern may also be formed by providing projections and recesses on the surface of the substrate. The surface of the substrate may be colored.

第１基板１０は、図２に示すように、表面１１と、裏面１２と、一端１３と、それに対向する他端１４と、別の一端１５と、それに対向する別の他端１６とを有している。一端１３には第１嵌合部（具体的な形状については図示せず）が形成されてもよく、他端１４には第２嵌合部（具体的な形状については図示せず）が形成されてもよい。別の他端１６は、表面１１が裏面１２よりも長くなるように斜めに切断されている。表面１１の面と別の他端１６の面がなす角は、鋭角であるが略４５度であってもよい。表面１１の面と別の一端１５の面がなす角は、略９０度であってもよい。裏面１２の面と別の一端１５の面がなす角は、略９０度であってもよい。裏面１２の面と別の他端１６の面がなす角は、鈍角であるが略１３５度であってもよい。また、表面１１に凹凸がある場合があるが表面１１の面と裏面１２の面とは、図２や図３に示すように略平行である。 As shown in FIG. 2, the first substrate 10 has a surface 11, a back surface 12, one end 13, an opposite end 14, another end 15, and another opposite end 16. A first fitting portion (the specific shape of which is not shown) may be formed at the one end 13, and a second fitting portion (the specific shape of which is not shown) may be formed at the other end 14. The other end 16 is cut obliquely so that the surface 11 is longer than the back surface 12. The angle between 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 between the surface of the surface 11 and the surface of the other end 15 may be approximately 90 degrees. The angle between the surface of the back surface 12 and the surface of the other end 15 may be approximately 90 degrees. The angle between 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. In addition, although the front surface 11 may have irregularities, the surface of the front surface 11 and the surface of the back surface 12 are approximately parallel as shown in Figures 2 and 3.

第２基板２０は、図２に示すように、表面２１と、裏面２２と、一端２３と、それに対向する他端２４と、別の一端２５と、それに対向する別の他端２６とを有している。一端２３には第１嵌合部（具体的な形状については図示せず）が形成されてもよく、他端２４には第２嵌合部（具体的な形状については図示せず）が形成されてもよい。別の一端２５は、表面２１が裏面２２よりも長くなるように斜めに切断されていてもよい。表面２１の面と別の一端２５の面がなす角は、鋭角であるが略４５度であってもよい。また、表面２１の面と別の他端２６の面がなす角は、略９０度であってもよい。また、裏面２２の面と別の他端２６の面がなす角は、略９０度であってもよい。裏面２２の面と別の一端２５の面がなす角は、鈍角であるが略１３５度であってもよい。また、表面２１に凹凸がある場合があるが表面２１の面と裏面２２の面とは、図２や図３に示すように略平行である。また、表面１１の面と別の他端１６の面がなす角と表面２１の面と別の一端２５の面がなす角の和が略９０度であることが好ましい。第１実施形態における出隅材の製造方法によって製造された出隅材を使用して建物の出隅付近の外壁を覆う場合、出隅材の表面２１の面を、その出隅材と直交関係にある他の外壁材の表面の面と略同一平面にすることができ、建物の見栄えをよくすることがきるからである。 As shown in FIG. 2, the second substrate 20 has a surface 21, a back surface 22, one end 23, an opposite end 24, another end 25, and another opposite end 26. A first fitting portion (specific shape not shown) may be formed at the one end 23, and a second fitting portion (specific shape not shown) may be formed at the other end 24. The other end 25 may be cut obliquely so that the surface 21 is longer than the back surface 22. The angle between the surface of the surface 21 and the surface of the other end 25 may be an acute angle, but may be approximately 45 degrees. The angle between the surface of the surface 21 and the surface of the other end 26 may be approximately 90 degrees. The angle between the surface of the back surface 22 and the surface of the other end 26 may be approximately 90 degrees. The angle between the surface of the back surface 22 and the surface of the other end 25 may be an obtuse angle, but may be approximately 135 degrees. Also, although the surface 21 may be uneven, the surface of the surface 21 and the surface of the back surface 22 are approximately parallel as shown in Figures 2 and 3. Also, it is preferable that the sum of the angle between the surface 11 and the surface of the other end 16 and the angle between the surface 21 and the surface of the other end 25 is approximately 90 degrees. When a corner material manufactured by the corner material manufacturing method in the first embodiment is used to cover an exterior wall near a corner of a building, the surface 21 of the corner material can be made approximately flush with the surface of the other exterior wall material that is perpendicular to the corner material, improving the appearance of the building.

製造者は、基板から第１基板１０と第２基板２０を切り出すために、裏面の面から反時計方向に鋭角に傾いた鋸やカッタ等を用意してもよい。製造者が基板を手前から、体から離れる方向に押して、第１基板を切り出す場合、他端１４から切り始め、一端１３で切り終わる。また、製造者が基板を手前から、体から離れる方向に押して、第２基板を切り出す場合、他端２３から切り始め、一端２４で切り終わる。この鋭角は略４５度であってもよい。 The manufacturer may prepare a saw or cutter inclined at an acute angle counterclockwise from the back surface to cut out the first substrate 10 and the second substrate 20 from the substrate. When the manufacturer pushes the substrate from the front away from the body to cut out the first substrate, the cut begins at the other end 14 and ends at one end 13. When the manufacturer pushes the substrate from the front away from the body to cut out the second substrate, the cut begins at the other end 23 and ends at one end 24. This acute angle may be approximately 45 degrees.

製造者は、基板から第１基板１０と第２基板２０を切り出すために、裏面の面から反時計方向に鈍角に傾いた鋸やカッタ等を用意してもよい。製造者が基板を手前から、体から離れる方向に押して、第１基板を切り出す場合、一端１３から切り始め、他端１４で切り終わる。また、製造者が基板を手前から、体から離れる方向に押して、第２基板を切り出す場合、一端２４から切り始め、他端２３で切り終わる。この鈍角は略１３５度であってもよい。 The manufacturer may prepare a saw or cutter inclined at an obtuse angle counterclockwise from the back surface to cut out the first substrate 10 and the second substrate 20 from the substrate. When the manufacturer pushes the substrate from the front away from the body to cut out the first substrate, the cut begins at one end 13 and ends at the other end 14. When the manufacturer pushes the substrate from the front away from the body to cut out the second substrate, the cut begins at one end 24 and ends at the other end 23. This obtuse angle may be approximately 135 degrees.

製造者は、基板から第１基板１０および第２基板２０を略一度に切り出すために、裏面の面から反時計方向に鋭角に傾いた鋸やカッタ等と、裏面の面から反時計方向に鈍角に傾いた鋸やカッタ等を用意してもよい。製造者が基板を手前から、体から離れる方向に押して、第１基板および第２基板を切り出す場合、第１基板の他端１４から切り始め第１基板の一端１３で切り終わり、第２基板の一端２４から切り始め第２基板の他端２３で切り終わる。この鋭角は略４５度であってもよい。この鈍角は略１３５度であってもよい。 In order to cut out the first substrate 10 and the second substrate 20 from the substrate at approximately one time, the manufacturer may prepare a saw or cutter tilted at an acute angle counterclockwise from the back surface, and a saw or cutter tilted at an obtuse angle counterclockwise from the back surface. When the manufacturer pushes the substrate from the front away from the body to cut out the first substrate and the second substrate, the cut starts from the other end 14 of the first substrate and ends at one end 13 of the first substrate, and starts from one end 24 of the second substrate 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.

第１基板１０と第２基板２０を用意した後、第１基板１０と第２基板２０を接着する（ステップＳ２０）。例えば、第１基板１０の別の他端１６と、第２基板２０の別の一端２５に接着剤を塗布し、それらの面を重ね合わせ、少なくとも第１基板１０の表面１１と第２基板２０の表面２１に力を加え且つ第１基板１０の裏面１２と第２基板２０の裏面２２がずれないようにささえることにより行われてもよい。 After preparing the first substrate 10 and the second substrate 20, the first substrate 10 and the second substrate 20 are bonded together (step S20). For example, this may be done by applying adhesive to the other end 16 of the first substrate 10 and the other end 25 of the second substrate 20, overlapping their surfaces, applying force to at least the front surface 11 of the first substrate 10 and the front surface 21 of the second substrate 20, and supporting the back surface 12 of the first substrate 10 and the back surface 22 of the second substrate 20 so that they do not shift.

また、第１基板１０の別の他端１６と、第２基板２０の別の一端２５に接着剤が塗布される前に、第１基板１０の別の他端１６と、第２基板２０の別の一端２５にプライマ処理のような下処理が行われてもよい。 In addition, before adhesive is applied to the other end 16 of the first substrate 10 and the other end 25 of the second substrate 20, a preparatory treatment such as a primer treatment may be performed on the other end 16 of the first substrate 10 and the other end 25 of the second substrate 20.

また、第１基板１０の別の他端１６と、第２基板２０の別の一端２５に接着剤が塗布された後、高周波接着機によって接着面に高周波電圧を印加することにより、接着速度を速めてもよい。その場合、接着剤としてウレタン系接着剤が使用されてもよい。 After 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 bonding speed may be increased by applying a high-frequency voltage to the bonding surfaces using a high-frequency bonding machine. In this case, a urethane-based adhesive may be used as the adhesive.

また、高周波接着機のような機械を使用することなく、自然養生で、第１基板１０と第２基板２０が、接着されてもよい。その場合、接着剤として、ポリウレタン系接着剤、ウレタン系接着剤、またはエポキシ系接着剤が接着面に塗布されていてもよい。 The first substrate 10 and the second substrate 20 may also be bonded by natural curing without using a machine such as a high-frequency bonding machine. In this case, a polyurethane adhesive, a urethane adhesive, or an epoxy adhesive may be applied to the bonding surfaces as the adhesive.

図３は、第１基板１０および第２基板２０を接着した中間部材３０の一例を示す図である。中間部材３０を第１基板の他端（図２における符号１４）からみた場合、中間部材３０は略Ｌ型をしている。 Figure 3 shows an example of an intermediate member 30 in which a first substrate 10 and a second substrate 20 are bonded together. When the intermediate member 30 is viewed from the other end of the first substrate (reference numeral 14 in Figure 2), the intermediate member 30 is substantially L-shaped.

出隅材を形成するため、第１基板１０の裏面１２にそろうように第２基板２０を切断する（ステップＳ３０）。例えば、破線２７に沿って、鋸やカッタ等にて第２基板２０の一部が切断される。切断された一部は、別の他端２６を含んでいる。 To form the corner material, the second substrate 20 is cut so as to be flush with the rear surface 12 of the first substrate 10 (step S30). For example, a portion of the second substrate 20 is cut along the dashed line 27 with a saw or cutter. The cut portion includes the other end 26.

以下に、図面を参照しながら本発明の第２実施形態における出隅材の製造方法について説明する。 The manufacturing method for the corner material in the second embodiment of the present invention will be described below with reference to the drawings.

図４は、第１基板１０および第２基板２０を接着した中間部材４０の一例を示す外観図である。 Figure 4 is an external view showing an example of an intermediate member 40 in which a first substrate 10 and a second substrate 20 are bonded together.

中間部材４０では、第１基板１０および第２基板２０の接着面から接着剤４１が第１基板１０および第２基板の表面に出てきている。第１基板１０および第２基板２０の接着面から接着剤があふれない適量を塗布することが好ましいが、接着剤の量が適量より少ないと、接着面に隙間ができ第１基板１０と第２基板２０を接着する強度が落ちる。このため、接着面に接着剤を適量より多めに塗布することになり、図４に示す中間部材４０が形成され得る。 In the intermediate member 40, adhesive 41 comes out from the bonding surfaces of the first substrate 10 and the second substrate 20 onto the surfaces of the first substrate 10 and the second substrate 20. It is preferable to apply an appropriate amount of adhesive so that the adhesive does not overflow from the bonding surfaces of the first substrate 10 and the second substrate 20, but if the amount of adhesive is less than the appropriate amount, gaps will form on the bonding surfaces and the strength of bonding the first substrate 10 and the second substrate 20 will decrease. For this reason, more adhesive than the appropriate amount will be applied to the bonding surfaces, and the intermediate member 40 shown in Figure 4 can be formed.

この場合、ステップＳ２０とステップＳ３０の間またはステップＳ３０の後に、中間部材４０の表面にある接着剤４１を除去する除去工程を設けることが好ましい。完成した出隅材の外観をよくするためである。 In this case, it is preferable to provide a removal step between steps S20 and S30 or after step S30 to remove the adhesive 41 on the surface of the intermediate member 40. This is to improve the appearance of the completed corner material.

また、第１基板１０および第２基板２０の接着面から接着剤が第１基板１０および第２基板の裏面に出てきている場合には、ステップＳ２０とステップＳ３０の間に中間部材４０の裏面にある接着剤を除去する除去工程を設けることが好ましい。後述する製造装置によって、第２基板２０の一部を綺麗に切断するためである。 In addition, if adhesive has come out from the adhesive surfaces of the first substrate 10 and the second substrate 20 onto the back surfaces of the first substrate 10 and the second substrate 20, it is preferable to provide a removal process between steps S20 and S30 to remove the adhesive on the back surface of the intermediate member 40. This is to allow a part of the second substrate 20 to be neatly cut off by the manufacturing device described below.

図５は、接着剤の除去の一例を説明するための図である。 Figure 5 is a diagram to explain an example of adhesive removal.

製造者が、中間部材５０の表面にある接着剤５１を除去する場合、図５に示すように、第１基板１０の表面の一部１７および第２基板２０の表面の一部１８を除去してもよい。言い換えると、中間部材５０のＬ型のコーナが面取りされていてもよい。第１基板１０と第２基板２０の接続部からはみ出している接着剤だけを取り除くことが難しいからである。中間部材５０のＬ型のコーナは、第１基板１０の尖った部分１７と第２基板２０の尖った部分２７からできており、中間部材５０の表面にある接着剤を切削等により綺麗に取り除く場合、少しでも深く削ると、先端部１７、２７が欠けたりして、最終完成品である出隅材の見栄えが悪くなる。また、製造者は、中間部材５０の裏面にある接着剤５２を除去する場合、中間部材５０の表面にある接着剤５１を除去するほど留意する必要はない。 When the manufacturer removes the adhesive 51 on the surface of the intermediate member 50, as shown in FIG. 5, the manufacturer may remove a portion 17 of the surface of the first substrate 10 and a portion 18 of the surface of the second substrate 20. 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 that protrudes from the connection between the first substrate 10 and the second substrate 20. The L-shaped corner of the intermediate member 50 is made up of the sharp portion 17 of the first substrate 10 and the sharp portion 27 of the second substrate 20, and when the adhesive on the surface of the intermediate member 50 is cleanly removed by cutting or the like, if the cutting is made even a little too deeply, the tips 17 and 27 may be chipped, which will deteriorate the appearance of the corner material, which is the final finished product. In addition, when the manufacturer removes the adhesive 52 on the back surface of the intermediate member 50, it is not necessary to be as careful as removing the adhesive 51 on the surface of the intermediate member 50.

このため、敢えて中間部材５０のＬ型のコーナについては面取りを行い、第１基板１０の尖った部分１７と第２基板２０の尖った部分２７を削ることにより、見栄えが悪くなる破損を生じなくすることができる。図５に示す例では、尖った部分１７における、中間部材５０のＬ型のコーナの頂点から第１基板１０の削り出されたところと削り出されていないところの境までの直線距離は、２ｍｍ～５ｍｍであってもよく、尖った部分２７における、中間部材５０のＬ型のコーナの頂点から第２基板２０の削り出されたところと削り出されていないところの境までの直線距離は、２ｍｍ～５ｍｍであってもよく、直線状５５（実際には１つの面）に面取りが行われているがこれに限られない。面取り部分が複数の線（実際には複数の面）で構成されていてもよい。面取り部分が円弧状（実際には曲面）で構成されていてもよい。また、直線状５５の長さは、２ｍｍ～７ｍｍであってもよい。 For this reason, the L-shaped corners of the intermediate member 50 are chamfered and the sharpened portion 17 of the first substrate 10 and the sharpened portion 27 of the second substrate 20 are cut to prevent damage that would cause a poor appearance. In the example shown in FIG. 5, the straight-line distance from the apex of the L-shaped corner of the intermediate member 50 to the boundary between the cut-out portion and the uncut portion of the first substrate 10 at the sharpened portion 17 may be 2 mm to 5 mm, and the straight-line distance from the apex of the L-shaped corner of the intermediate member 50 to the boundary between the cut-out portion and the uncut portion of the second substrate 20 at the sharpened portion 27 may be 2 mm to 5 mm, and the chamfering is performed in a straight line 55 (actually one surface), but is not limited to this. The chamfered portion may be composed of multiple lines (actually multiple surfaces). The chamfered portion may be composed of an arc (actually a curved surface). The length of the straight line 55 may be 2 mm to 7 mm.

接着剤とともに、第１基板１０の表面の一部および第２基板２０の表面の一部を除去する場合、除去後（ステップＳ３０の前または後）に、除去により削られた部分に彩色が施されてもよい。彩色する色は、第１基板１０および第２基板２０と略同じ色であることが好ましい。 When a part of the surface of the first substrate 10 and a part of the surface of the second substrate 20 are removed together with the adhesive, the parts removed by the removal may be colored after the removal (before or after step S30). It is preferable that the color to be applied is substantially the same as the color of the first substrate 10 and the second substrate 20.

以下に、図面を参照しながら本発明の第３実施形態における出隅材の製造方法について説明する。 The manufacturing method for the corner material in the third embodiment of the present invention will be described below with reference to the drawings.

図６は、本発明の第３実施形態における出隅材の製造方法を示す流れ図である。図７は、その出隅材の製造方法の一例を説明するための、その中間部材の図である。 Figure 6 is a flow diagram showing a method for manufacturing a corner member in a third embodiment of the present invention. Figure 7 is a diagram of an intermediate part to explain an example of a method for manufacturing the corner member.

製造者は、図７（ａ）に示すような第１基板６０、第２基板７０および第３基板８０を用意する（ステップＳ１１０）。第１基板６０、第２基板７０および第３基板８０は、１枚の基板から切り出されてもよい（図７（ａ））。その基板は、表面６１、７１、８１と、裏面６２、７２、８２と、一端６３、７３、８３、その一端６３、７３、８３に対向する他端と、別の一端７５、その別の一端７５に対向する別の他端８６とを有し、図７（ａ）に示す正面図の横方向（以下、Ｘ方向という）における基板の長さは２００ｍｍ～４５０ｍｍであってもよい。また、その基板の奥行きは、４００ｍｍ～５００ｍｍであってもよい。また、その基板の厚さは、１５ｍｍ～２０ｍｍであってもよい。 The manufacturer prepares the first substrate 60, the second substrate 70, and the third substrate 80 as shown in FIG. 7(a) (step S110). The first substrate 60, the second substrate 70, and the third substrate 80 may be cut out from a single substrate (FIG. 7(a)). The substrate has a front surface 61, 71, 81, a back surface 62, 72, 82, an end 63, 73, 83, an end opposite the end 63, 73, 83, another end 75, and another end 86 opposite the end 75. The length of the substrate in the horizontal direction (hereinafter referred to as the X direction) of the front view shown in FIG. 7(a) may be 200 mm to 450 mm. The depth of the substrate may be 400 mm to 500 mm. The thickness of the substrate may be 15 mm to 20 mm.

基板同士を接続するために、基板の一端６３、７３、８３には、第１実施形態と同様に第１嵌合部が形成されていてもよい。基板同士を接続するために、基板の一端６３、７３、８３に対向する他端には、第１実施形態と同様に第２嵌合部が形成されていてもよい。また、基板の材質は、第１実施形態と同様であってもよい。基板の表面には、模様が形成されていてもよい。また、この模様は、基板の表面に凹凸を設けることにより、形成されてもよい。基板の表面は、着色されていてもよい。 In order to connect the substrates to each other, a first mating portion may be formed at one end 63, 73, 83 of the substrate as in the first embodiment. In order to connect the substrates to each other, a second mating portion may be formed at the other end opposite to one end 63, 73, 83 of the substrate as in the first embodiment. The material of the substrate may be the same as that of the first embodiment. A pattern may be formed on the surface of the substrate. This pattern may be formed by providing projections and recesses on the surface of the substrate. The surface of the substrate may be colored.

第１基板６０は、図７（ａ）に示すように、表面６１と、裏面６２と、一端６３と、それに対向する他端と、別の一端６５と、それに対向する別の他端６６とを有している。第１基板６０において、一端６３には第１嵌合部（具体的な形状については図示せず）が形成されてもよく、他端には第２嵌合部（具体的な形状については図示せず）が形成されてもよい。別の一端６５および別の他端６６は、Ｘ方向における表面６１の長さが裏面６２の長さよりも長くなるように斜めに切断されていてもよい。表面６１の面と別の一端６５の面がなす角は、鋭角であってもよい。表面６１の面と別の他端６６の面がなす角は、鋭角であってもよい。また、裏面６２の面と別の一端６５の面がなす角は、鈍角であってもよい。また、裏面６２の面と別の他端６６の面がなす角は、鈍角であってもよい。これらの鋭角は、略４５度であってもよい。また、これらの鈍角は略１３５度であってもよい。 As shown in FIG. 7(a), the first substrate 60 has a surface 61, a back surface 62, one end 63, the other end opposite thereto, another end 65, and another end opposite thereto. In the first substrate 60, a first fitting portion (the specific shape of which is not shown) may be formed at the one end 63, and a second fitting portion (the specific shape of which is not shown) may be formed at the other end. The other end 65 and the other end 66 may be cut obliquely so that the length of the surface 61 in the X direction is longer than the length of the back surface 62. The angle formed by the surface of the surface 61 and the surface of the other end 65 may be an acute angle. The angle formed by the surface of the surface 61 and the surface of the other end 66 may be an acute angle. The angle formed by the surface of the back surface 62 and the surface of the other end 65 may be an obtuse angle. The angle formed by the surface of the back surface 62 and the surface of the other end 66 may be an obtuse angle. These acute angles may be approximately 45 degrees. These obtuse angles may also be approximately 135 degrees.

第２基板７０は、図７（ａ）に示すように、表面７１と、裏面７２と、一端７３と、それに対向する他端と、別の一端７５と、それに対向する別の他端７６とを有している。第２基板７０において、一端７３には第１嵌合部（具体的な形状については図示せず）が形成されてもよく、他端には第２嵌合部（具体的な形状については図示せず）が形成されてもよい。別の他端７６は、Ｘ方向における表面７１の長さが裏面７２の長さよりも長くなるように斜めに切断されていてもよい。表面７１の面と別の一端７５の面がなす角は、略９０度であってもよい。表面７１の面と別の他端７６の面がなす角は、鋭角であってもよい。また、裏面７２の面と別の一端７５の面がなす角は、略９０度であってもよい。また、裏面７２の面と別の他端７６の面がなす角は、鈍角であってもよい。この鋭角は、略４５度であってもよい。また、この鈍角は略１３５度であってもよい。また、第１実施形態と同様の理由により、表面６１の面と別の一端６５の面がなす角と表面７１の面と別の他端７６の面がなす角の和が略９０度であることが好ましい。 7A, the second substrate 70 has a surface 71, a back surface 72, one end 73, an opposite end, another end 75, and another opposite end 76. In the second substrate 70, a first fitting portion (the specific shape of which is not shown) may be formed at the one end 73, and a second fitting portion (the specific shape of which is not shown) may be formed at the other end. The other end 76 may be cut obliquely so that the length of the surface 71 in the X direction is longer than the length of the back surface 72. The angle between the surface of the surface 71 and the surface of the other end 75 may be approximately 90 degrees. The angle between the surface of the surface 71 and the surface of the other end 76 may be an acute angle. The angle between the surface of the back surface 72 and the surface of the other end 75 may be approximately 90 degrees. The angle between the surface of the back surface 72 and the surface of the other end 76 may be an obtuse angle. This acute angle may be approximately 45 degrees. This obtuse angle may also be approximately 135 degrees. For the same reasons as in the first embodiment, it is preferable that the sum of the angle between the surface 61 and the surface of the other end 65 and the angle between the surface 71 and the surface of the other end 76 is approximately 90 degrees.

第３基板８０は、図７（ａ）に示すように、表面８１と、裏面８２と、一端８３と、それに対向する他端と、別の一端８５と、それに対向する別の他端８６とを有している。第３基板８０において、一端８３には第１嵌合部（具体的な形状については図示せず）が形成されてもよく、他端には第２嵌合部（具体的な形状については図示せず）が形成されてもよい。別の一端８５は、Ｘ方向における表面８１の長さが裏面８２の長さよりも長くなるように斜めに切断されていてもよい。表面８１の面と別の一端８５の面がなす角は、鋭角であってもよい。表面８１の面と別の他端８６の面がなす角は、略９０度であってもよい。また、裏面８２の面と別の一端８５の面がなす角は、鈍角であってもよい。また、裏面８２の面と別の他端８６の面がなす角は、略９０度であってもよい。この鋭角は、略４５度であってもよい。また、この鈍角は略１３５度であってもよい。また、第１実施形態と同様の理由により、表面６１の面と別の他端６６の面がなす角と表面８１の面と別の一端８５の面がなす角の和が略９０度であることが好ましい。 As shown in FIG. 7(a), the third substrate 80 has a surface 81, a back surface 82, one end 83, the other end opposite thereto, another end 85, and another end opposite thereto. In the third substrate 80, a first fitting portion (the specific shape of which is not shown) may be formed at the one end 83, and a second fitting portion (the specific shape of which is not shown) may be formed at the other end. The other end 85 may be cut obliquely so that the length of the surface 81 in the X direction is longer than the length of the back surface 82. The angle formed by the surface of the surface 81 and the surface of the other end 85 may be an acute angle. The angle formed by the surface of the surface 81 and the surface of the other end 86 may be approximately 90 degrees. The angle formed by the surface of the back surface 82 and the surface of the other end 85 may be an obtuse angle. The angle formed by the surface of the back surface 82 and the surface of the other end 86 may be approximately 90 degrees. This acute angle may be approximately 45 degrees. This obtuse angle may also be approximately 135 degrees. For the same reasons as in the first embodiment, it is preferable that the sum of the angle between the surface 61 and the surface of the other end 66 and the angle between the surface 81 and the surface of the other end 85 is approximately 90 degrees.

１枚の基板から、第２基板７０を切り出す場合、製造者は、例えば、その基板のＸ方向から反時計方向に鋭角に傾いた丸鋸の刃によって、別の他端７６を形成しつつ、その基板から第２基板２０を切り出してもよい。この鋭角は、略４５度であってもよい。 When cutting out the second substrate 70 from one substrate, the manufacturer may, for example, use a circular saw blade inclined at an acute angle counterclockwise from the X direction of the substrate to form the other end 76 while cutting out the second substrate 20 from the substrate. This acute angle may be approximately 45 degrees.

製造者は、その基板のＸ方向から反時計方向に略４５度傾いた丸鋸の刃によって第２基板７０を切り出した後、第１基板６０を切り出す場合、製造者は、例えばその基板のＸ方向から反時計方向に鈍角に傾いた丸鋸の刃によって、別の一端６５を形成し、その基板のＸ方向から反時計方向に鋭角に傾いた丸鋸の刃によって別の他端６６を形成することにより、第１基板６０が切り出されてもよい。この鈍角は略１３５度であってもよい。また、この鋭角は、略４５度であってもよい。 When the manufacturer cuts out the second substrate 70 with a circular saw blade inclined at approximately 45 degrees counterclockwise from the X direction of the substrate, and then cuts out the first substrate 60, the manufacturer may, for example, form another end 65 with a circular saw blade inclined at an obtuse angle counterclockwise from the X direction of the substrate, and form another end 66 with a circular saw blade inclined at an acute angle counterclockwise from the X direction of the substrate, thereby cutting out the first substrate 60. This obtuse angle may be approximately 135 degrees. Also, this acute angle may be approximately 45 degrees.

第３基板８０を切り出す場合、製造者は、例えば、その基板のＸ方向から反時計方向に鈍角に傾いた丸鋸の刃によって別の一端８５を形成し、第３基板８０が切り出されてもよい。この鈍角は略１３５度であってもよい。 When cutting out the third substrate 80, the manufacturer may, for example, form another end 85 with a circular saw blade tilted at an obtuse angle counterclockwise from the X direction of the substrate, and cut out the third substrate 80. This obtuse angle may be approximately 135 degrees.

上述した例では、第１基板６０、第２基板７０、第３基板８０という順番でそれぞれが切り出されたが、上述した例と同様の方法を使い、第３基板８０、第１基板６０、第２基板７０という順番でそれぞれが切り出されてもよい。また、第１基板６０、第２基板７０および第３基板８０は、第１実施形態と同様に切り出されてもよい。 In the above example, the first substrate 60, the second substrate 70, and the third substrate 80 are cut out in this order, but the third substrate 80, the first substrate 60, and the second substrate 70 may be cut out in this order using a method similar to that of the above example. Also, 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.

第１基板６０、第２基板７０および第３基板８０を用意した後、第１基板６０と第２基板７０を接着する（ステップＳ１２０）。例えば、第１基板６０の別の一端６５と、第２基板７０の別の他端７６に接着剤を塗布し、それらの面を重ね合わせ、少なくとも第１基板６０の表面６１と第２基板７０の表面７１に力を加え且つ第１基板６０の裏面６２と第２基板７０の裏面７２がずれないようにささえることにより行われてもよい。 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 together (step S120). For example, this may be done by applying adhesive to the other end 65 of the first substrate 60 and the other end 76 of the second substrate 70, overlapping their surfaces, applying force to at least the front surface 61 of the first substrate 60 and the front surface 71 of the second substrate 70, and supporting the back surface 62 of the first substrate 60 and the back surface 72 of the second substrate 70 so that they do not shift.

第１基板６０と第２基板７０を接着した後、第１基板６０と第３基板８０を接着する（ステップＳ１２２）。例えば、第１基板６０の別の他端６６と、第３基板８０の別の一端８５に接着剤を塗布し、それらの面を重ね合わせ、少なくとも第１基板６０の表面６１と第３基板８０の表面８１に力を加え且つ第１基板６０の裏面６２と第３基板８０の裏面８２がずれないようにささえることにより行われてもよい。 After bonding the first substrate 60 and the second substrate 70, the first substrate 60 and the third substrate 80 are bonded together (step S122). For example, this may be done by applying adhesive to the other end 66 of the first substrate 60 and the other end 85 of the third substrate 80, overlapping their surfaces, applying force to at least the front surface 61 of the first substrate 60 and the front surface 81 of the third substrate 80, and supporting the back surface 62 of the first substrate 60 and the back surface 82 of the third substrate 80 so that they do not shift.

また、第１基板６０の別の一端６５と、第２基板７０の別の他端７６に接着剤が塗布される前に、第１基板６０の別の一端６５と、第２基板７０の別の他端７６にプライマ処理のような下処理が行われてもよい。同様に、第１基板６０の別の他端６６と、第３基板８０の別の一端８５に接着剤が塗布される前に、第１基板６０の別の他端６６と、第３基板８０の別の一端８５にプライマ処理のような下処理が行われてもよい。 Also, before adhesive is applied to the other end 65 of the first substrate 60 and the other end 76 of the second substrate 70, a pretreatment such as a primer treatment may be performed on the other end 65 of the first substrate 60 and the other end 76 of the second substrate 70. Similarly, before adhesive is applied to the other end 66 of the first substrate 60 and the other end 85 of the third substrate 80, a pretreatment such as a primer treatment may be performed on the other end 66 of the first substrate 60 and the other end 85 of the third substrate 80.

図７（ｂ）および（ｃ）に示すように、第１基板６０、第２基板７０、および第３基板８０は、高周波接着機によって接着されてもよい。高周波接着機によってそれぞれの基板が接着される場合、接着剤として、ウレタン系接着剤が接着面に塗布されていてもよい。例えば、高周波接着機の電極９１、９２に高周波の電圧をかけることにより、自然養生に比べ短時間で接着することができる。 As shown in Figures 7(b) and (c), the first substrate 60, the second substrate 70, and the third substrate 80 may be bonded by a high-frequency bonding machine. When the substrates are bonded by a high-frequency bonding machine, a urethane adhesive may be applied to the bonding surfaces as the adhesive. For example, by applying a high-frequency voltage to the electrodes 91 and 92 of the high-frequency bonding machine, bonding can be completed in a shorter time than by natural curing.

ただし、高周波接着機のような機械を使用することなく、自然養生で、第１基板６０、第２基板７０、および第３基板８０が、接着されてもよい。その場合、接着剤として、ポリウレタン系接着剤、ウレタン系接着剤、またはエポキシ系接着剤が接着面に塗布されていてもよい。自然養生する場合、高周波溶接機等の設備を備える必要はない。 However, the first substrate 60, the second substrate 70, and the third substrate 80 may be bonded by natural curing without using a machine such as a high-frequency bonding machine. In this case, a polyurethane-based adhesive, a urethane-based adhesive, or an epoxy-based adhesive may be applied to the bonding surfaces as an adhesive. When natural curing is used, there is no need to provide equipment such as a high-frequency welding machine.

図８（ａ）は、第１基板６０、第２基板７０および第３基板８０が接着された中間部材９８の一例を示す図であり、図８（ｂ）は、中間部材９８から第３基板８０の一部を切断した中間部材９９の一例を示す図である。中間部材９８は、略コの字型をしている。 Figure 8(a) is a diagram showing an example of an intermediate member 98 in which a first substrate 60, a second substrate 70, and a third substrate 80 are bonded, and Figure 8(b) is a diagram showing an example of an intermediate member 99 in which a part of the third substrate 80 is cut from the intermediate member 98. The intermediate member 98 has a roughly U-shape.

中間部材９８から、第１基板６０の裏面６２にそろうように第２基板７０および第３基板８０の一方を切断し、中間部材９９を形成する（ステップＳ１３０）。図８（ａ）に示す例では、破線９５に沿って、鋸やカッタ等にて第３基板８０の一部が切断される。切断された一部は、別の他端８６を含んでいる。 One of the second substrate 70 and the third substrate 80 is cut from the intermediate member 98 so as to align with the rear surface 62 of the first substrate 60, forming an intermediate member 99 (step S130). In the example shown in FIG. 8(a), a portion of the third substrate 80 is cut along the dashed line 95 with a saw or cutter. The cut portion includes the other end 86.

次に、出隅材を形成するため、中間部材９９から、第１基板６０の裏面６２にそろうように第２基板７０および第３基板８０の他方を切断する（ステップＳ１３２）。図８（ｂ）に示す例では、破線９６に沿って、鋸やカッタ等にて第２基板７０の一部が切断される。切断された一部は、別の一端７５を含んでいる。 Next, to form the corner material, the other of the second substrate 70 and the third substrate 80 is cut from the intermediate member 99 so as to align with the rear surface 62 of the first substrate 60 (step S132). In the example shown in FIG. 8(b), a portion of the second substrate 70 is cut along the dashed line 96 with a saw or cutter. The cut portion includes the other end 75.

この第３実施形態における出隅材の製造工程では、上述した第２実施形態における出隅材の製造工程と同様に、接着剤の除去が行われていてもよい。 In the manufacturing process of the corner member in this third embodiment, the adhesive may be removed in the same manner as in the manufacturing process of the corner member in the second embodiment described above.

以下に、図面を参照しながら本発明の第４実施形態における製造装置について説明する。 The manufacturing apparatus according to the fourth embodiment of the present invention will be described below with reference to the drawings.

図９は、ステップＳ３０において、第２基板２０の一部を切断するための製造装置１００の一例を示す図である。 Figure 9 shows an example of a manufacturing apparatus 100 for cutting a portion of the second substrate 20 in step S30.

本発明の第４実施形態における製造装置１００は、第１基板１０をガイドする第１ガイド１１０と第２基板２０をガイドする第２ガイド１２０とを有し、中間部材３０を通過させる通路部１３０と、鉛直軸を法線とする面で、第１基板１０の裏面にそろうように第２基板２０の一部を切断する切断器１４０と、第１ガイド１１０に第１基板１０を押しつけ、搬送する第１送り部１５０と、第２ガイド１２０に第２基板２０を押しつけ、搬送する第２送り部１６０とを備えている。 The manufacturing apparatus 100 in the fourth embodiment of the present invention has a first guide 110 that guides the first substrate 10 and a second guide 120 that guides the second substrate 20, a passage section 130 that passes the intermediate member 30, a cutter 140 that cuts a part of the second substrate 20 in a plane normal to the vertical axis so as to align with the rear surface of the first substrate 10, a first feed section 150 that presses the first substrate 10 against the first guide 110 and transports it, and a second feed section 160 that presses the second substrate 20 against the second guide 120 and transports it.

第１ガイド１１０は、中間部材３０が製造装置１００中を移動する際に、摩擦を小さくするような構成を有している。例えば、第１ガイド１１０は、複数のローラにより形成されてもよい。 The first guide 110 has a configuration that reduces friction when the intermediate member 30 moves through the manufacturing apparatus 100. For example, the first guide 110 may be formed of multiple rollers.

同様に、第２ガイド１２０は、中間部材３０が製造装置１００中を移動する際に、摩擦を小さくするような構成を有している。例えば、第２ガイド１２０は、複数のローラにより形成されてもよい。 Similarly, the second guide 120 has a configuration that reduces friction when the intermediate member 30 moves through the manufacturing apparatus 100. For example, the second guide 120 may be formed of multiple rollers.

切断器１４０は、鋸であってもよい。切断器１４０が鋸である場合、往復運動をするものよりも回転運動するものが好ましい。モータ等の動力源からの回転運動を一度往復運動に変換する必要がないからである。 The cutter 140 may be a saw. If the cutter 140 is a saw, it is preferable that the cutter has a rotary motion rather than a reciprocating motion. This is because there is no need to convert the rotary motion from a power source such as a motor into a reciprocating motion first.

また、切断器１４０が、略鉛直軸を法線とする面、言い換えると略水平面で、第１基板１０の裏面１２にそろうように第２基板２０の一部を切断することができるため、以下の効果を奏する。 In addition, the cutter 140 can cut a portion of the second substrate 20 so as to be aligned with the rear surface 12 of the first substrate 10 in a plane normal to a substantially vertical axis, in other words, in a substantially horizontal plane, thereby achieving the following effects.

例えば、通常の丸鋸のように丸鋸が縦に回転し、縦方向で第２基板２０の一部を切断する場合、第２基板２０の表面２１が上向きとなり、第１基板１０の表面１１が横向きとなり流れる。第１基板の大きさは、第２基板の大きさよりも大きく、それぞれの自重も、第２基板に比べ第１基板が重い。第１基板１０の自重と梃子の原理によって第１基板１０が僅かに切断部から離れ、第１基板１０側にある第２基板２０の切断される部分が僅かに増えて、第１基板１０に残る第２基板２０の切断部分が切り始めよりも切り終わりの方が切断器１４０により深く切られる。しかし、この第４実施形態のように横方向で第２基板２０の一部を切断すると、第２基板は、第１基板に比べ軽いため、上述した変化は僅かである。 For example, when the circular saw rotates vertically like a normal circular saw and cuts a part of the second substrate 20 vertically, the surface 21 of the second substrate 20 faces upward, and the surface 11 of the first substrate 10 faces horizontally and flows. The size of the first substrate is larger than the size of the second substrate, and the weight of each is also 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 moves slightly away from the cutting portion, the cut portion of the second substrate 20 on the first substrate 10 side increases slightly, and the cut portion of the second substrate 20 remaining on the first substrate 10 is cut deeper by the cutter 140 at the end of the cut than at the beginning of the cut. However, when cutting a part of the second substrate 20 horizontally as in this fourth embodiment, the second substrate is lighter than the first substrate, so the above-mentioned change is slight.

また、横方向で第２基板２０の一部を切断する場合、第１基板１０の表面１１が上向きになり流れてくるため、製造者は、面積の広い第１基板１０の表面１１の外観をチェックしながら作業をすることができ、不良品を選別することができる。 In addition, when cutting a portion of the second substrate 20 horizontally, the surface 11 of the first substrate 10 flows upward, allowing the manufacturer to work while checking the appearance of the large surface 11 of the first substrate 10, and thus enabling the manufacturer to select defective products.

また、横方向で第２基板２０の一部を切断する場合、第１基板１０の表面１１が上向きになり流れてくるため、製造者は、第１基板１０の表面１１が横になり流れてくる場合に比べて作業がしやすい。例えば、製造者が切断された出隅材を集積する場合、第１基板１０の表面１１が上を向いている出隅材を手に取り移動させればよい。しかし、横方向で第２基板２０の一部を切断する場合、表面が横を向いている出隅材を手に取り移動させる必要がある。作業を正確にするためには、両手で出隅材を持つことになるが、表面が横を向いている出隅材を両手で受け取るには、一方の肩が下がり、製造者は不自然な状態を繰り返ししなくてはならず、製造者に負担が掛かる。 In addition, when cutting a portion of the second substrate 20 in the horizontal direction, the surface 11 of the first substrate 10 flows upward, making it easier for the manufacturer to work than when the surface 11 of the first substrate 10 flows horizontally. For example, when the manufacturer is stacking the cut corner pieces, he or she can simply pick up and move the corner pieces with the surface 11 of the first substrate 10 facing upward. However, when cutting a portion of the second substrate 20 in the horizontal direction, it is necessary to pick up and move the corner pieces with the surface facing horizontally. To work accurately, the corner pieces are held with both hands, but to receive a corner piece with the surface facing horizontally with both hands, one shoulder is lowered, and the manufacturer must repeatedly perform this unnatural position, which places a burden on the manufacturer.

以下、切断器１４０が丸鋸である場合について説明する。切断器１４０は、モータ１４１により回転する。製造装置１００は、切断器１４０の位置を変えることができる機構を備えていてもよい。例えば、モータ１４１はレール１４２に沿って、上下に移動させることが可能である。また、レール１４２は、台座１４３に取り付けられている。台座１４３は、機構１４４により、第１ガイド１１０または第２ガイド１２０から離れたり、近づいたりすることができる。 The following describes the case where the cutter 140 is a circular saw. The cutter 140 rotates by a motor 141. The manufacturing apparatus 100 may be equipped with a mechanism that can change the position of the cutter 140. For example, the motor 141 can be moved up and down along a rail 142. In addition, the rail 142 is attached to a base 143. The base 143 can be moved away from or towards the first guide 110 or the second guide 120 by a mechanism 144.

第１送り部１５０は、第１ガイド１１０に第１基板１０を押しつけ、中間部材３０を搬送する。第１送り部１５０は、輪っか状の第１ベルト１５１と第１モータ１５２を有していてもよい。第１モータ１５２が回転することにより、第１ベルト１５１が回転し、中間部材３０が搬送される。 The first feed section 150 presses the first substrate 10 against the first guide 110 and transports the intermediate member 30. The first feed section 150 may have a loop-shaped first belt 151 and a first motor 152. When the first motor 152 rotates, the first belt 151 rotates and the intermediate member 30 is transported.

また、第２送り部１６０は、第２ガイド１２０に第２基板２０を押しつけ、中間部材３０を搬送する。第２送り部１６０は、輪っか状の第２ベルト１６１と第２モータ１６２を有していてもよい。第２モータ１６２が回転することにより、第２ベルト１６１が回転し、中間部材３０が搬送される。第２送り部１６０が第２ガイド１２０に第２基板２０を押しつけるため、第１基板１０側にある第２基板２０の切断される面に変動が殆ど生じず、第１基板１０と接着されている第２基板２０の切断面は綺麗にまっすぐ切断される。 The second feed section 160 presses the second substrate 20 against the second guide 120 and transports the intermediate member 30. The second feed section 160 may have a loop-shaped second belt 161 and a second motor 162. The second motor 162 rotates, causing the second belt 161 to rotate and transporting the intermediate member 30. Because the second feed section 160 presses the second substrate 20 against the second guide 120, there is almost no variation in the surface to be cut of the second substrate 20 on the first substrate 10 side, and the cut surface of the second substrate 20 bonded to the first substrate 10 is cut neatly and straight.

図１０は、製造装置１００における、第１ベルト１５１と第２ベルト１６１がある位置の一例を示す模式的な図である。図１０では、第１ベルト１５１および第２ベルト１６１については、中間部材３０を第１ガイド１１０および第２ガイド１２０に押されつけている部分についてのみ記載しており、モータ等については、その記載を省略している。 Figure 10 is a schematic diagram showing an example of the positions of the first belt 151 and the second belt 161 in the manufacturing apparatus 100. In Figure 10, the first belt 151 and the second belt 161 are shown only in the portions where the intermediate member 30 is pressed against the first guide 110 and the second guide 120, and the motors and the like are not shown.

図１０における左側から右側に中間部材３０が搬送されている。中間部材３０は、第１ベルト１５１と第１ガイド１１０に挟まれ、さらに、第２ベルト１６１と第２ガイド１２０に挟まれ移動する。図１０における左側から右側に中間部材３０が搬送されている場合、切断器１４０は、反時計方向に回転する。 The intermediate member 30 is transported from the left to the right in FIG. 10. The intermediate member 30 is sandwiched between the first belt 151 and the first guide 110, and further sandwiched between the second belt 161 and the second guide 120. When the intermediate member 30 is transported from the left to the right in FIG. 10, the cutter 140 rotates counterclockwise.

切断器１４０付近において、第１ガイド１１０は切り欠け部１１１を有している。同様に、切断器１４０付近において、第２ガイド１２０は切り欠け部１２１を有している。切断器１４０が第１基板１０の裏面１２の面にて、第２基板２０の一部を切断する場合、切断器１４０付近において、第１ガイド１１０および第２ガイド１２０が中間部材３０をガイドしていると、誤差０で切断器１４０が第２基板２０の一部を切断することとなり、切断器１４０の刃こぼれにつながる。このため、切断器１４０付近において、切り欠け部１１１、１２１が設けられている。 The first guide 110 has a notch 111 near the cutter 140. Similarly, the second guide 120 has a notch 121 near the cutter 140. When the cutter 140 cuts a part of the second substrate 20 on the rear surface 12 of the first substrate 10, if the first guide 110 and the second guide 120 are guiding the intermediate member 30 near the cutter 140, the cutter 140 will cut a part of the second substrate 20 with zero error, which will lead to chipping of the blade of the cutter 140. For this reason, the notches 111 and 121 are provided near the cutter 140.

なお、切り欠け部１１１は、第１ガイド１１０の全範囲に渡り設けられていてもよい。同様に、切り欠け部１２１は、第２ガイド１２０の全範囲に渡り設けられていてもよい。第１基板１０の裏面１２と第２基板２０の裏面２２との角には、接着剤の削除不良や、付着した接着剤を削除する際の過度の切削の可能性があり、また、その角から漏れ出る接着剤を除去しないとすると、その角を基準として、中間部材を搬送することは好ましくないからである。 The notch 111 may be provided over the entire range of the first guide 110. Similarly, the notch 121 may be provided over the entire range of the second guide 120. At the corner between the rear surface 12 of the first substrate 10 and the rear surface 22 of the second substrate 20, there is a possibility that the adhesive may not be properly removed or that excessive cutting may occur when removing the applied adhesive. In addition, if the adhesive leaking from the corner is not removed, it is not preferable to transport the intermediate member based on the corner.

また、第１基板１０の裏面１２の面にて、第２基板２０の一部を切断するためには、中間部材３０が、切断器１４０の回転軸方向並びに、切断器１４０の回転軸方向および中間部材３０の進行方向に垂直な方向１８０にぶれないように、中間部材３０を押さえる必要がある。このため、第１送り部１５０は、第１ベルト１５１で第１基板１０の表面１１を第１ガイド１１０に押し付け、切断器１４０の回転軸方向にぶれないようにする。また、中間部材３０を上下方向に振動させる主な震動源は、切断器１４０であるため、中間部材３０を介して、切り欠け部１１１付近の第１ガイド１１０を第１ベルト１５１が押すことが好ましい。また、第１ベルト１５１において中間部材３０を押さえつけている部分の長さは、丸鋸の直径よりも長くてもよい。 In addition, in order to cut a part of the second substrate 20 on the surface of the back surface 12 of the first substrate 10, it is necessary to hold the intermediate member 30 so that it does not wobble in the direction of the rotation axis of the cutter 140 and in the direction 180 perpendicular to the direction of the rotation axis of the cutter 140 and the direction of travel of the intermediate member 30. For this reason, the first feed section 150 presses the front surface 11 of the first substrate 10 against the first guide 110 with the first belt 151 to prevent it from wobbling in the direction of the rotation axis of the cutter 140. In addition, since the main source of vibration that vibrates the intermediate member 30 in the vertical direction is the cutter 140, it is preferable that the first belt 151 presses the first guide 110 near the notch 111 via the intermediate member 30. In addition, 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.

同様に、第２送り部１６０は、第２ベルト１６１で第２基板２０の表面２１を第２ガイド１２０に押し付け、方向１８０にぶれないようにする。また、中間部材３０を方向１８０に振動させる主な震動源は、切断器１４０であるため、中間部材３０を介して、切り欠け部１２１付近の第２ガイド１２０を第２ベルト１６１が押すことが好ましい。また、第２ベルト１６１において中間部材３０を押さえつけている部分の長さは、丸鋸の直径よりも長くてもよい。また、第１ベルト１５１において中間部材３０を押さえつけている部分の長さは、第２ベルト１６１において中間部材３０を押さえつけている部分の長さと略同じであってもよい。 Similarly, the second feed section 160 presses the surface 21 of the second substrate 20 against the second guide 120 with the second belt 161 to prevent it from vibrating in the direction 180. Since the main source of vibration that vibrates the intermediate member 30 in the direction 180 is the cutter 140, it is preferable that the second belt 161 presses the second guide 120 near the notch 121 via the intermediate member 30. The length of the portion of the second belt 161 that presses the intermediate member 30 may be longer than the diameter of the circular saw. The length of the portion of the first belt 151 that presses the intermediate member 30 may be approximately the same as the length of the portion of the second belt 161 that presses the intermediate member 30.

また、第２ベルト１６１は、切断器１４０の下に配置されている。言い換えると、第２ベルト１６１は、第２ガイド１２０のうち、第１基板１０から切断器１４０を介して遠い位置に配置されている。このため、第２ベルト１６１が第２基板２０を非常に強く第２ガイド１２０に押しつけたしても、製品となる出隅材の表面を傷つけることがない。 The second belt 161 is also positioned below the cutter 140. In other words, the second belt 161 is positioned in the second guide 120 at a position far from the first substrate 10 via the cutter 140. Therefore, even if the second belt 161 presses the second substrate 20 very strongly against the second guide 120, the surface of the corner material to be the finished product is not damaged.

切断器１４０は、金属製のカバーで覆われていてもよい。製造者が切断器１４０によって身体を傷付けることを防止するためである。また、カバーには、基板等の削りかす等を吸引する吸引ダクトが接続されていてもよい。カバー内に削りかす等がたまり、切断器１４０の回転が悪くなることを避けるためである。また、カバーに吸引ダクトを設ける場合、カバーにさらに吸気ダクトを設けることが好ましい。単にカバーに吸気用の穴をあけただけでは、製造者が切断器１４０によって身体を傷付けることがあるからである。また、吸気ダクトを設けることにより、吸引力をアップさせることができる。 The cutter 140 may be covered with a metal cover. This is to prevent the manufacturer from injuring himself with the cutter 140. The cover may also be connected to a suction duct that sucks in shavings from circuit boards and the like. This is to prevent shavings from accumulating inside the cover and impairing the rotation of the cutter 140. When a suction duct is provided on the cover, it is preferable to also provide an air intake duct on the cover. This is because the manufacturer may injure himself with the cutter 140 if only an intake hole is drilled in the cover. Also, providing an air intake duct can increase the suction power.

中間部材３０を用いて製造装置１００の動作を説明したが、中間部材３０の代わりに、上述したように中間部材４０から接着剤４１を取り除いた部材、中間部材５０から先端部１７、２７接着剤５１、５２を取り除いた部材等が用いられても、出隅材を製造することができる。 The operation of the manufacturing device 100 has been explained using the intermediate member 30, but instead of the intermediate member 30, it is also possible to manufacture corner pieces by using a member obtained by removing the adhesive 41 from the intermediate member 40 as described above, or a member obtained by removing the adhesive 51 and 52 from the tip portions 17 and 27 from the intermediate member 50, etc.

また、製造装置１００に、中間部材９８またはそこから表面のコーナおよび裏面のコーナからはみ出た少なくとも一方の接着剤を取り除いた部材を流すことにより、第２基板７０または第３基板８０の一部が切断されてもよい。同様に、製造装置１００に、中間部材９９またはそこから表面のコーナおよび裏面のコーナからはみ出た少なくとも一方の接着剤を取り除いた部材を流し、第２送り部１６０が第３基板８０を第２ガイド１２０に押しつけることにより、第３基板８０の一部が切断されてもよい。また、中間部材９８から先に第３基板８０の一部が切断された場合、その後、第２基板７０の一部が製造装置１００によって切断されてもよい。 Also, a part of the second substrate 70 or the third substrate 80 may be cut by feeding the intermediate member 98 or a member from which at least one of the adhesives protruding from the corners of the front surface and the corners of the back surface has been removed, through the manufacturing apparatus 100. Similarly, a part of the third substrate 80 may be cut by feeding the intermediate member 99 or a member from which at least one of the adhesives protruding from the corners of the front surface and the corners of the back surface has been removed, through the manufacturing apparatus 100, and the second feed section 160 pressing the third substrate 80 against the second guide 120. Also, if a part of the third substrate 80 is cut first from the intermediate member 98, a part of the second substrate 70 may then be cut by the manufacturing apparatus 100.

製造装置１００は、第３基板８０をガイドする第３ガイドと、第３ガイドに第３基板８０を押しつけ搬送する第３送り部と、第１基板６０の裏面にそろうように第３基板８０の一部を切断する第２切断器とをさらに備えていてもよい。また、第３ガイド、第３送り部および第２切断器は、通路部１３０を介して第２ガイド１２０、第２送り部１６０および切断器１４０の略反対側に配置されていてもよい。このように、製造装置１００が、第３ガイド、第３送り部および第２切断器をさらに備えている場合、中間部材９８を一度この装置に通しただけで、第２基板７０の一部および第３基板８０の一部を切断することができる。このように、製造装置１００が第３ガイドと、第３送り部と、第２切断器とをさらに備えていても、中間部材９８の表面のコーナおよび裏面のコーナからはみ出た少なくとも一方の接着剤を取り除いた部材から第２基板７０の一部および第３基板８０の一部を切断することができることは言うまでもない。 The manufacturing apparatus 100 may further include a third guide for guiding the third substrate 80, a third feed section for pressing and transporting the third substrate 80 against the third guide, and a second cutter for cutting a portion of the third substrate 80 so as to align with the rear surface of the first substrate 60. The third guide, the third feed section, and the second cutter may be disposed on the substantially opposite side of the second guide 120, the second feed section 160, and the cutter 140 via the passage section 130. In this way, when the manufacturing apparatus 100 further includes the third guide, the third feed section, and the second cutter, a portion of the second substrate 70 and a portion of the third substrate 80 can be cut by passing the intermediate member 98 through this apparatus only once. In this way, even if the manufacturing device 100 further includes a third guide, a third feed section, and a second cutter, it goes without saying that it is possible to cut a portion of the second substrate 70 and a portion of the third substrate 80 from the intermediate member 98 after removing at least one of the adhesives protruding from the front corner and the back corner of the intermediate member 98.

製造装置１００が第２切断器を備えている場合、第２切断器を配置するために、第１ガイドが切り欠け部１１１と同様の第３切り欠け部を第２切断器付近に有し、第３ガイドが第２ガイドの欠け部１２１と同様の第４切り欠け部を第２切断器付近に有していることが好ましい。第２切断器の刃こぼれを防止するためである。 When the manufacturing apparatus 100 is equipped with a second cutter, it is preferable that the first guide has a third cutout portion similar to cutout portion 111 near the second cutter in order to position the second cutter, and that the third guide has a fourth cutout portion similar to cutout portion 121 of the second guide near the second cutter. This is to prevent the blade of the second cutter from chipping.

また、製造装置１００が第２切断器を備えている場合、第３送り部が第２切断器の下部に配置されていることが好ましい。このため、第３送り部が第２切断器の下部で第３基板を第３ガイドに押しつけるため、切断器が発生する振動を効率よく吸収することができる。 In addition, when the manufacturing apparatus 100 is equipped with a second cutter, it is preferable that the third feed section is disposed below the second cutter. Therefore, the third feed section presses the third substrate against the third guide below the second cutter, so that the vibrations generated by the cutter can be efficiently absorbed.

第２切断器は、丸鋸であってもよい。往復運動する鋸に比べて機構を簡単にすることができるからである。 The second cutter may be a circular saw, as this allows for a simpler mechanism than a reciprocating saw.
