Description

本発明は、Ｌ型部材を製造するＬ型部材の製造方法に関する。   The present invention relates to an L-shaped member manufacturing method for manufacturing an L-shaped member.

従来より、Ｌ型部材の製造方法としては、角材に切欠加工を施して製造する方法や、角材（板材）の一方面に略Ｖ型の溝を設け、この溝の部位で折曲加工することで製造する方法が知られている。このような製造方法では、角材の切り欠かれた部位が無駄となったり、精度良く角材（板材）の一方面に略Ｖ型の溝を設ける必要が生じたりすることが考えられるため、さらなる改善が望まれていた。
例えば、下記特許文献１では、角材の表裏面の各々から１条ずつ長さ方向に通しで平行かつ互いに一直線上に交わることなく所要の深さまで垂直に鋸目を入れる工程を有したＬ型部材の製造方法が提案されている。当該Ｌ型部材の製造方法では、上記工程に次いで、表裏面以外の両側面から圧縮または引張することによりせん断破壊を起こして切断し２本のＬ型部材を得、これら２本のＬ型部材の表面に塩化ビニルシート化粧を施す構成とされている。 Conventionally, as a method of manufacturing an L-shaped member, a method of manufacturing a square member by performing a notch process, or providing a substantially V-shaped groove on one surface of a square member (plate member), and bending the portion of the groove is performed. The manufacturing method is known. In such a manufacturing method, it is conceivable that the notched portion of the square bar is wasted or it is necessary to provide a substantially V-shaped groove on one side of the square bar (plate member) with high accuracy. Was desired.
For example, in the following Patent Document 1, an L-shaped member having a step of making a saw mark vertically to a required depth without crossing one straight line from the front and back surfaces of each square bar in parallel in the length direction. The manufacturing method of this is proposed. In the manufacturing method of the L-shaped member, following the above steps, the two L-shaped members are obtained by causing shear fracture by compressing or pulling from both side surfaces other than the front and back surfaces to obtain two L-shaped members. The surface is made of vinyl chloride sheet makeup.

しかしながら、上記特許文献１のＬ型部材の製造方法では、２本のＬ型部材を製造した後に、これら２本のＬ型部材の表面に塩化ビニルシート化粧を施す構成とされている。そのため、２本のＬ型部材のそれぞれの表面に化粧シートを貼着する必要があるので、貼着工程が煩雑化することが考えられる。また、比較的に複雑な形状のＬ型部材の表面に化粧シートを貼着する必要があるため、化粧シートの貼着装置が複雑化したり、精度良く化粧シートを貼着し難くなることが考えられる。   However, in the manufacturing method of the L-shaped member of Patent Document 1 described above, after the two L-shaped members are manufactured, the surface of these two L-shaped members is subjected to vinyl chloride sheet makeup. Therefore, since it is necessary to stick a decorative sheet on the surface of each of the two L-shaped members, the sticking process may be complicated. Moreover, since it is necessary to stick a decorative sheet on the surface of a relatively complicated L-shaped member, it is considered that the decorative sheet sticking device becomes complicated or it is difficult to stick the decorative sheet with high accuracy. It is done.

本発明は上記実情に鑑みてなされたものであり、製造効率を向上し得るＬ型部材の製造方法を提供することを目的とする。   This invention is made | formed in view of the said situation, and it aims at providing the manufacturing method of the L-shaped member which can improve manufacturing efficiency.

A groove is formed so that each bottom portion is substantially in the same position in the depth direction substantially parallel to each other over substantially the entire length in the longitudinal direction and substantially perpendicular to each of the front and back surfaces. The bottom of the groove is divided into front and back sides.

本発明においては、前記Ｌ型部材は、前記切り溝によって形成された切断面を先端面とする一方の片部が、戸枠の枠本体に設けられた凹所に受け入れられる枠部材として用いられるものとしてもよい。
また、本発明においては、前記切り溝の少なくとも一方が形成される部位に継目が位置するように前記化粧シートを貼着するようにしてもよい。 In the present invention, the L-shaped member is used as a frame member in which one piece having a cutting surface formed by the kerf as a tip surface is received in a recess provided in a frame body of a door frame.

As shown in FIG. 1, the decorative sheet 11 is brought into contact with both end edges of the decorative sheet 11 wound around the four circumferential surfaces 10a, 10a, 10b, and 10b to form a joint 11a. You may make it stick so that. Or you may make it stick so that a slight clearance gap may be formed as the seam 11a between the both ends of the said decorative sheet 11. FIG. Furthermore, you may make it stick so that the both ends edge part of the said decorative sheet 11 may overlap slightly, and the joint 11a may be formed. In this embodiment, since the kerf 12 is formed along the joint 11a of the decorative sheet 11, the necessity for adhering both edge portions of the decorative sheet 11 with high accuracy, that is, in abutment is reduced. Thus, the sticking process can be simplified.

化粧シート１１の長尺角材１０への貼着態様としては、例えば、化粧シート１１をロール状に巻き取った繰り出し装置から化粧シート１１を繰り出しながら、長尺角材１０を移動させて、化粧シート１１を長尺角材１０に貼着するようにしてもよい。

It is good also as an aspect which compresses and cuts in the width direction.
As an aspect of compressing in the width direction and dividing into front and back, for example, along the transport direction on both sides of the width direction so that the interval between the compression rollers gradually narrows toward the front side in the transport direction of the kerf forming square 10B Further, it may be divided by introducing the kerf forming square member 10B into a compression device in which a plurality of compression rollers are arranged. Thereby, the kerf forming square member 10B is compressed from both sides in the width direction, shear deformation occurs in a virtual plane connecting the bottom portions 12a, 12a of the two kerf members 12, 12, and the kerf forming square member 10B is divided into the front and back sides.
Or it is good also as an aspect which compresses the kerf formation square 10B mounted on the stand from the width direction both sides or the width direction one side.

また、上記のような切溝形成角材１０Ｂを幅方向に圧縮して表裏に分断する態様に代えて、切溝形成角材１０Ｂを幅方向に引っ張ることで、切溝形成角材１０Ｂを表裏に分断する態様としてもよい。例えば、台上に載置された切溝形成角材１０Ｂの幅方向両側部位を適宜の把持装置により把持し、切溝形成角材１０Ｂを幅方向に引っ張る。これにより、切溝形成角材１０Ｂの両切り溝１２，１２の底部１２ａ，１２ａ同士を繋ぐ仮想面にせん断変形が生じ、切溝形成角材１０Ｂが表裏に分断される。
また、上記のような切溝形成角材１０Ｂを幅方向に圧縮したり、引っ張ったりすることで、切溝形成角材１０Ｂを表裏に分断する態様に代えて、切溝形成角材１０Ｂの長手方向両端面における両切り溝１２，１２の底部１２ａ，１２ａ同士を繋ぐ仮想面に沿ってくさびを打ち込んで、くさび効果により切溝形成角材１０Ｂを表裏に分断するようにしてもよい。
または、切溝形成角材１０Ｂの長手方向両端面における上記仮想面に沿ってくさびを打ち込んで分断補助溝を形成し、次いで、上記のように切溝形成角材１０Ｂを幅方向に圧縮したり、引っ張ったりすることで、切溝形成角材１０Ｂを表裏に分断するようにしてもよい。
上記のように、本実施形態では、長尺角材１０を熱圧成形により形成されたＭＤＦとしているので、厚さ方向中心側部位が軟らかくなるため、両切り溝１２，１２の底部１２ａ，１２ａ同士の間を種々の態様によって容易に表裏に分断することができる。 Moreover, it replaces with the aspect which compresses the cut groove formation square material 10B in the above width directions, and divides into the front and back, and divides the cut groove formation square material 10B into the front and back by pulling the cut groove formation square material 10B in the width direction. It is good also as an aspect. For example, the both sides in the width direction of the kerf forming square member 10B placed on the table are gripped by an appropriate gripping device, and the kerf forming square member 10B is pulled in the width direction. Thereby, shear deformation arises in the virtual surface which connects the bottom parts 12a and 12a of both the cut grooves 12 and 12 of the cut groove forming square member 10B, and the cut groove forming square member 10B is divided into the front and back sides.
Moreover, it replaces with the aspect which divides the kerf formation square 10B into the front and back by compressing or pulling the kerf formation square 10B in the width direction as described above, and both longitudinal ends of the kerf formation square 10B. Alternatively, a wedge may be driven along a virtual plane that connects the bottoms 12a of the both kerfs 12 and 12, and the kerf forming square member 10B may be divided into front and back by a wedge effect.
Alternatively, a wedge is driven along the imaginary surface on both longitudinal ends of the kerf forming square member 10B to form a cutting assisting groove, and then the kerf forming square member 10B is compressed or pulled in the width direction as described above. By doing so, the kerf forming square member 10B may be divided into front and back sides.
As described above, in the present embodiment, since the long square member 10 is an MDF formed by hot pressing, since the central portion in the thickness direction is soft, the bottom portions 12a and 12a of the both kerfs 12 and 12 are The gap can be easily divided into the front and back sides according to various embodiments.

当該Ｌ型部材の製造方法において製造された二本のＬ型部材１，１は、切り溝１２，１２によって形成された切断面１２ｂ，１２ｂを先端面とする一方の片部１ａ，１ａと、この一方の片部１ａ，１ａに直交するように設けられた他方の片部１ｂ，１ｂと、を備えている。また、これらＬ型部材１，１は、これら一方の片部１ａ，１ａと他方の片部１ｂ，１ｂとによって、長手方向に見て略Ｌ字状に形成されている。図例では、これら二本のＬ型部材１，１のそれぞれの一方の片部１ａ，１ａを他方の片部１ｂ，１ｂよりも長尺とした例を示している。
これら二本のＬ型部材１，１のそれぞれは、それぞれの長手方向両端面を除く、外周面のうち、両切り溝１２，１２によって形成された切断面１２ｂ，１２ｂ及び上記分断工程により分断された分断面１２ｃ，１２ｃを除いた面に化粧シート１１が貼着されている。つまり、これら二本のＬ型部材１，１のそれぞれは、一方の片部１ａ，１ａの外側面、他方の片部１ｂ，１ｂの外側面及び他方の片部１ｂ，１ｂの先端面に化粧シート１１が貼着されている。 The two L-shaped members 1, 1 manufactured in the manufacturing method of the L-shaped member include one piece 1 a, 1 a with the cut surfaces 12 b, 12 b formed by the kerfs 12, 12 as the tip surfaces, The other piece 1b, 1b provided so as to be orthogonal to the one piece 1a, 1a. The L-shaped members 1 and 1 are formed in an approximately L shape when viewed in the longitudinal direction by the one piece portions 1a and 1a and the other piece portions 1b and 1b. In the illustrated example, the one piece 1a, 1a of each of the two L-shaped members 1, 1 is longer than the other piece 1b, 1b.
Each of these two L-shaped members 1, 1 is divided by the above-described cutting step and the cut surfaces 12 b, 12 b formed by the both-cut grooves 12, 12 on the outer peripheral surface excluding the respective longitudinal end faces. A decorative sheet 11 is adhered to the surface excluding the divided sections 12c and 12c. That is, each of these two L-shaped members 1, 1 has a makeup on the outer surface of one piece 1 a, 1 a, the outer surface of the other piece 1 b, 1 b, and the tip surface of the other piece 1 b, 1 b. A sheet 11 is attached.

上記構成とされた本実施形態に係るＬ型部材１の製造方法によれば、製造効率を向上させることができる。
つまり、当該Ｌ型部材１の製造方法によれば、長尺角材１０を表裏面１０ａ，１０ａの両切り溝１２，１２の底部１２ａ，１２ａ同士の間を表裏に分断することで、１本の長尺角材１０から２本のＬ型部材１，１を製造することができる。従って、長尺角材の切欠部位の無駄や、精度良く板材等に略Ｖ型の溝を設ける必要等が生じることがなく、Ｌ型部材１の製造効率を向上させることができる。
また、長尺角材１０の四周面１０ａ，１０ａ，１０ｂ，１０ｂに化粧シート１１を貼着した後に、その表裏面のそれぞれに対して切り溝１２，１２を形成するようにしている。従って、２本のＬ型部材を製造した後に、これら２本のＬ型部材の外周表面に化粧シート１１を貼着する態様とした場合と比べて、化粧シート１１の貼着効率を向上させることができる。また、比較的に複雑な形状のＬ型部材ではなく、長尺角材１０の四周面１０ａ，１０ａ，１０ｂ，１０ｂに化粧シート１１を貼着する態様としているので、化粧シート１１の貼着装置が複雑化したり、化粧シート１１の貼着ずれ等を抑制することができる。つまり、上記のように２本のＬ型部材のそれぞれに化粧シートを貼着する態様において、例えば、各Ｌ型部材の全周面に化粧シートを貼着する態様とした場合には、化粧シートの貼着面が多くなり、化粧シートの貼着装置や貼着工程等が複雑化することが考えられる。また、Ｌ型部材の各片部の少なくとも内側面に化粧シートを貼着しないような態様とした場合には、貼着面と非貼着面（内側面等）との境界（稜線部）にその化粧シートの端縁を貼着ずれ等を生じさせずに沿わせて貼着することは困難となることが考えられる。本実施形態に係るＬ型部材１の製造方法によれば、このように化粧シート１１の貼着装置や貼着工程等が複雑化したり、化粧シート１１の貼着ずれ等が生じることを抑制することができる。 According to the manufacturing method of the L-shaped member 1 according to the present embodiment configured as described above, the manufacturing efficiency can be improved.
That is, according to the manufacturing method of the L-shaped member 1, the long square member 10 is divided between the bottom portions 12 a, 12 a of both the cut grooves 12, 12 of the front and back surfaces 10 a, 10 a, so that one long Two L-shaped members 1, 1 can be manufactured from the shank member 10. Therefore, there is no waste of the notch portion of the long rectangular material, and it is not necessary to provide a substantially V-shaped groove in the plate material with high accuracy, and the manufacturing efficiency of the L-shaped member 1 can be improved.
Moreover, after adhering the decorative sheet 11 to the four peripheral surfaces 10a, 10a, 10b, and 10b of the long square member 10, kerfs 12 and 12 are formed on the front and back surfaces, respectively. Therefore, after manufacturing the two L-shaped members, the efficiency of applying the decorative sheet 11 is improved as compared with the case where the decorative sheet 11 is applied to the outer peripheral surface of the two L-shaped members. Can do. Moreover, since it is set as the aspect which affixes the decorative sheet 11 on the four peripheral surfaces 10a, 10a, 10b, 10b of the elongate square material 10 instead of the L-shaped member of a comparatively complicated shape, the sticking apparatus of the decorative sheet 11 is used. It is possible to complicate or suppress the sticking deviation of the decorative sheet 11 and the like. That is, in the aspect in which the decorative sheet is adhered to each of the two L-shaped members as described above, for example, when the decorative sheet is adhered to the entire circumferential surface of each L-shaped member, the decorative sheet It is conceivable that the number of sticking surfaces increases, and the sticking device and the sticking process of the decorative sheet become complicated. Moreover, when it is set as the aspect which does not stick a decorative sheet on at least an inner surface of each piece part of L-shaped member, it is on the boundary (ridgeline part) of a sticking surface and a non-sticking surface (inner side surface etc.). It is conceivable that it is difficult to stick the edge of the decorative sheet along the edge without causing sticking displacement or the like. According to the manufacturing method of the L-shaped member 1 according to the present embodiment, it is possible to prevent the sticking device, the sticking process, and the like of the decorative sheet 11 from becoming complicated as described above, and the sticking deviation of the decorative sheet 11 from occurring. be able to.

また、本実施形態では、切り溝１２の少なくとも一方が形成される部位に継目１１ａが位置するように化粧シート１１を貼着するようにしているので、継目１１ａに沿って切り溝１２が形成されることとなり、化粧シート１１の継目１１ａが切り溝１２の形成により消失する。これにより、化粧シート１１の継目１１ａがその他の部位に現れることがないので、Ｌ型部材１の見栄えを向上させることができる。   Moreover, in this embodiment, since the decorative sheet 11 is stuck so that the seam 11a is located at a site where at least one of the kerfs 12 is formed, the kerfs 12 are formed along the seam 11a. Thus, the joint 11a of the decorative sheet 11 disappears due to the formation of the cut groove 12. Thereby, since the joint 11a of the decorative sheet 11 does not appear in other parts, the appearance of the L-shaped member 1 can be improved.
