しかしながら、上述した従来の巻き付け装置を用いて扉１を製造する場合、第１のローラによって表面材３を第２溝部３ｂに沿って折り曲げる際に、表面材３は第２溝部３ｂに沿ってだけでなく、第１溝部３ａに沿って折れ曲がろうとする。このとき、表面材３が第１溝部３ａに沿って折り曲げられると、その分、埋没部３ｅの側部３ｄに対する折り曲げ角度が小さくなり、その結果、一対の表面材３の双方の埋没部３ｅが芯材２の凹部２ｃに埋没されないといった不具合が生じるという問題点があった。 However, when manufacturing the door 1 using the above-described conventional winding device, when the surface material 3 is bent along the second groove 3b by the first roller, the surface material 3 is only along the second groove 3b. Instead, it tries to bend along the first groove 3a. At this time, when the surface material 3 is bent along the first groove portion 3a, the bending angle of the buried portion 3e with respect to the side portion 3d is reduced, and as a result, both buried portions 3e of the pair of surface materials 3 are formed. There was a problem that a problem that the core material 2 was not buried in the recess 2c occurred.

また、上述した従来の巻き付け装置では、第１のローラを埋没部３ｅに当接させた際に、表面材３を第２溝部３ｂに沿って折り曲げつつ、第１溝部３ａに沿って折れ曲がることを防止するために、側部３ｄの一面側を支持する部材を搬送装置に別途設けることにより不具合を回避する必要があった。そのため、巻き付け装置の構造が複雑化し、製造コストが嵩むという問題点があった。 Further, in the above-described conventional winding device, when the first roller is brought into contact with the buried portion 3e, the surface material 3 is bent along the second groove portion 3b while being bent along the first groove portion 3a. In order to prevent this, it is necessary to avoid a problem by separately providing a member for supporting one surface side of the side portion 3d in the transport device. For this reason, there is a problem that the structure of the winding device becomes complicated and the manufacturing cost increases.

本発明は、上述した問題点を解決するためになされたものであり、製造コストを抑制しつつ、扉の製造時における不具合を低減できる扉製造装置を提供することを目的としている。 The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a door manufacturing apparatus that can reduce defects at the time of manufacturing a door while suppressing manufacturing costs.

課題を解決するための手段および発明の効果Means for Solving the Problems and Effects of the Invention

請求項１記載の扉製造装置によれば、巻き込み部材は、側部の他面側に当接することで表面材を第１溝部に沿って折り曲げる第１折り曲げ部と、その第２折り曲げ部よりも搬送装置の搬送方向下流側に位置し埋没部の他面側に当接することで表面材を第２溝部に沿って折り曲げる第２折り曲げ部と、側部および埋没部を押し込んで埋没部を芯材の凹部に埋没させる押し込み部とを備えている。 According to the door manufacturing apparatus of the first aspect, the entrainment member is more in contact with the other surface side of the side portion than the first bent portion that bends the surface material along the first groove portion and the second bent portion. A second bending portion for bending the surface material along the second groove portion by contacting the other surface side of the embedded portion located on the downstream side in the conveying direction of the conveying device; and pushing the side portion and the embedded portion into the core portion as the core portion And a pushing portion to be buried in the recess.

これにより、搬送装置の幅方向両側に配設された巻き込み部材の間に芯材および表面材が搬送されると、一対の表面材は、第１折り曲げ部により第１溝部に沿って側部が中央部に対して所定の角度まで折り曲げられた状態で、第２折り曲げ部により第２溝部に沿って埋没部が側部に対して折り曲げられた後、押し込み部により側部および埋没部を押し込むことができるので、一対の表面材の各々の埋没部を凹部に埋没させやすくすることができる。よって、扉の製造時において、一対の表面材の双方の埋没部が凹部に埋没されないといった不具合を低減させることができるという効果がある。 As a result, when the core material and the surface material are conveyed between the entraining members disposed on both sides in the width direction of the conveying device, the pair of surface materials have side portions along the first groove portion by the first bent portion. The buried portion is bent with respect to the side portion along the second groove portion by the second bent portion in a state bent to a predetermined angle with respect to the central portion, and then the side portion and the buried portion are pushed in by the pushing portion. Therefore, each buried part of the pair of surface materials can be easily buried in the recessed part. Therefore, at the time of manufacturing the door, there is an effect that it is possible to reduce a problem that both the buried portions of the pair of surface materials are not buried in the recess.

また、表面材を第２溝部に沿って折り曲げた後に第１溝部に沿って折り曲げる場合のように、側部の一面側を支持する部材を搬送装置に設けることを不要とすることができるので、巻き込み部材の構成を簡素化でき、その結果、扉製造装置の製造コストを抑制できるという効果がある。 In addition, since it is possible to eliminate the need to provide a member that supports one side of the side portion in the transport device, as in the case of bending the surface material along the first groove portion after the surface material is bent along the second groove portion, The configuration of the entraining member can be simplified, and as a result, the manufacturing cost of the door manufacturing apparatus can be suppressed.

請求項２記載の扉製造装置によれば、請求項１記載の扉製造装置の奏する効果に加え、第１折り曲げ部は、側部の他面側に当接可能に構成された複数のローラを備え、それら複数のローラが搬送装置の搬送方向に沿って配設されると共に、搬送装置の搬送方向下流側に位置するものほど搬送装置の幅方向内側に寄せて配設されているので、複数のローラの外周面を表面材の他面側に当接させることで、表面材を第１溝部に沿って徐々に折り曲げることができる。 According to the door manufacturing apparatus of the second aspect, in addition to the effect produced by the door manufacturing apparatus of the first aspect, the first bent portion includes a plurality of rollers configured to be in contact with the other surface side of the side portion. The plurality of rollers are arranged along the conveying direction of the conveying device, and the one positioned on the downstream side of the conveying device in the conveying direction is arranged closer to the inner side in the width direction of the conveying device. By bringing the outer peripheral surface of the roller into contact with the other surface side of the surface material, the surface material can be gradually bent along the first groove portion.

これにより、表面材を第１溝部に沿って一度に折り曲げる場合と比べて、表面材の長手方向全体を第１溝部に沿って確実に折り曲げることができるという効果がある。 Thereby, compared with the case where a surface material is bent along a 1st groove part at once, there exists an effect that the whole longitudinal direction of a surface material can be reliably bent along a 1st groove part.

また、第１折り曲げ部が、複数のローラを回転可能に保持することにより構成されているので、側部にローラが当接することにより側部の他面側が傷つくことを回避しやすくすることができるという効果がある。 Moreover, since the 1st bending part is comprised by hold | maintaining a some roller rotatably, it can make it easy to avoid that the other surface side of a side part is damaged when a roller contact | abuts to a side part. There is an effect.

請求項３記載の扉製造装置によれば、請求項１記載の扉製造装置の奏する効果に加え、第１折り曲げ部は、側部に当接可能な平面状の平面部を備え、その平面部の搬送装置の搬送方向下流側に位置する部分が、搬送装置の搬送方向上流側に位置する部分よりも、搬送装置の幅方向内側に寄せて配設されているので、平面部を表面材の他面側に当接させることで、表面材を第１溝部に沿って徐々に折り曲げることができる。
According to the door manufacturing apparatus according to claim 3, in addition to the effect produced by the door manufacturing apparatus according to claim 1, the first bent portion includes a flat planar portion capable of contacting the side portion, and the planar portion. since a portion located in the conveying direction lower stream side of the conveying device is, than the portion positioned in the conveying direction on the upstream side of the conveying device, are disposed closer to the widthwise inner side of the conveying device, the surface of the planar portion By abutting on the other surface side of the material, the surface material can be gradually bent along the first groove portion.

これにより、表面材を第１溝部に沿って一度に折り曲げる場合と比べて、表面材の長手方向全体を第１溝部に沿って確実に折り曲げることができるので、埋没部を芯材の凹部に埋没させる際の不具合を回避しやすくすることができるという効果がある。 As a result, the entire longitudinal direction of the surface material can be reliably bent along the first groove portion as compared with the case where the surface material is bent along the first groove portion at a time, so that the buried portion is buried in the concave portion of the core material. There is an effect that it is possible to easily avoid a problem at the time of making it happen .

請求項４記載の扉製造装置によれば、請求項１から３のいずれかに記載の扉製造装置の奏する効果に加え、第２折り曲げ部が、外周面が側部に当接可能に構成されたテーパ状の側部当接部と、外周面が埋没部に当接可能に構成されたテーパ状の埋没部当接部とを備え、外周面が断面視略Ｗ字状に形成されたＷ状折り曲げ部を備えているので、Ｗ状折り曲げ部を表面材の他面側に当接させることで、一対の表面材の各々の側部が互いに離間する方向へ変位することを側部当接部によって規制しつつ、一対の表面材の各々の埋没部を埋没部当接部によって芯材の端面部により近接した位置まで押し込むことができる。これにより、一対の表面材の各々の埋没部を凹部へ埋没させやすくすることができるので、扉の製造時における不具合を低減させることができるという効果がある。 According to the door manufacturing apparatus of the fourth aspect, in addition to the effect produced by the door manufacturing apparatus according to any one of the first to third aspects, the second bent portion is configured such that the outer peripheral surface can come into contact with the side portion. W having a tapered side contact portion and a tapered buried portion contact portion whose outer peripheral surface is configured to be able to contact the buried portion, the outer peripheral surface being formed in a substantially W shape in cross section. Since the W-shaped bent portion is brought into contact with the other surface side of the surface material, the side portions of the pair of surface materials are displaced in a direction away from each other. While being regulated by the portion, each buried portion of the pair of surface materials can be pushed to a position closer to the end surface portion of the core material by the buried portion abutting portion. Thereby, since each buried part of the pair of surface materials can be easily buried in the recess, there is an effect that it is possible to reduce problems during the manufacture of the door.

図２に示すように、位置決め部３０は、搬送装置１０に回転可能に保持された略円板状の部位であり、位置決め部３０の回転軸が上下方向へ向けられている。 As shown in FIG. 2, the positioning unit 30 is a substantially disk-shaped portion that is rotatably held by the transport device 10, and the rotation axis of the positioning unit 30 is directed in the vertical direction.

搬送装置１０の左右両側に配設された位置決め部３０の離間間隔は、芯材２の幅寸法、即ち、一対の端面部２ｂの離間間隔よりも小さく、かつ、一対の凹部２ｃの底面（図２における凹部２ｃの右側の面）の離間間隔と同等以上となるように設定されると共に、搬送装置１０上を芯材２が搬送される際に凹部２ｃが通過する高さ位置に位置決め部３０が配設されている。 The spacing interval between the positioning portions 30 disposed on the left and right sides of the transport device 10 is smaller than the width dimension of the core member 2, that is, the spacing interval between the pair of end surface portions 2b, and the bottom surfaces of the pair of recesses 2c (see FIG. 2 is set to be equal to or greater than the separation interval of the concave portion 2c on the right side), and the positioning portion 30 is at a height position where the concave portion 2c passes when the core material 2 is conveyed on the conveying device 10. Is arranged.

搬送装置１０の左右両側に配置された位置決め部３０の間に芯材２及び表面材３が通過する際、芯材２が位置決め部３０の間を通過する。このとき、芯材２及び表面材３が、搬送装置１０上の左右いずれかへずれた位置に配置された状態で、左右両側に配置された位置決め部３０の間に搬送された場合には、位置決め部３０の外周面が芯材２に当接する。これにより、芯材２が左右両側に配置された位置決め部３０の間を通過するように案内され、芯材２及び表面材３を搬送装置１０上の適切な位置に配置できる。 When the core material 2 and the surface material 3 pass between the positioning portions 30 arranged on the left and right sides of the transport device 10, the core material 2 passes between the positioning portions 30. At this time, when the core material 2 and the surface material 3 are transported between the positioning portions 30 disposed on the left and right sides in a state where the core material 2 and the surface material 3 are disposed at positions shifted to either the left or right on the transport device 10, The outer peripheral surface of the positioning part 30 contacts the core material 2. Thereby, the core material 2 is guided so as to pass between the positioning portions 30 arranged on the left and right sides, and the core material 2 and the surface material 3 can be arranged at appropriate positions on the transport device 10.

よって、位置決め部３０の後方に配設される第１折り曲げ部４０、第２折り曲げ部５０及び押し込み部６０を表面材３の適切な位置に当接させることができる。従って、表面材３の幅方向（図２左右方向）両側を、第１溝部３ａ及び第２溝部３ｂに沿って確実に折り曲げることができるので、芯材２に表面材３を巻き付ける際の不具合を回避しやすくすることができる。 Therefore, the 1st bending part 40, the 2nd bending part 50, and the pushing part 60 which are arrange | positioned behind the positioning part 30 can be made to contact | abut at the appropriate position of the surface material 3. FIG. Therefore, both sides in the width direction (left and right direction in FIG. 2) of the surface material 3 can be reliably bent along the first groove portion 3a and the second groove portion 3b. It can be easily avoided.

次に、図３を参照して、第１折り曲げ部４０について説明する。図３（ａ）は、図１のＩＩＩａ部分における搬送装置１０の部分拡大上面図であり、図３（ｂ）は、図３（ａ）のＩＩＩｂ方向から視た第１折り曲げ部４０の側面図であり、図３（ｃ）は、図３（ａ）のＩＩＩｃ方向から視た第１折り曲げ部４０の側面図である。なお、図３（ａ）では、図面を簡素化して簡略に説明するため、第１溝部３ａ及び第２溝部３ｂの位置を破線で模式的に図示している。 Next, the first bent portion 40 will be described with reference to FIG. 3A is a partially enlarged top view of the transfer device 10 in the IIIa portion of FIG. 1, and FIG. 3B is a side view of the first bent portion 40 viewed from the IIIb direction of FIG. 3A. FIG. 3C is a side view of the first bent portion 40 viewed from the IIIc direction in FIG. In FIG. 3A, the positions of the first groove portion 3a and the second groove portion 3b are schematically illustrated by broken lines in order to simplify and simplify the drawing.

図３に示すように、第１折り曲げ部４０は、車輪状に形成されると共に搬送装置１０に回転可能に保持された上下一対のローラ４１を備えている。上下一対のローラ４１は、上下方向に対称に設けられると共に、上下一対のローラ４１の回転軸が、搬送装置１０の左右方向中央部分から外側へ向けて互いに近接するように傾斜している。 As shown in FIG. 3, the first bent portion 40 includes a pair of upper and lower rollers 41 that are formed in a wheel shape and are rotatably held by the transport device 10. The pair of upper and lower rollers 41 are provided symmetrically in the vertical direction, and the rotation shafts of the pair of upper and lower rollers 41 are inclined so as to approach each other from the central portion in the left and right direction of the transport device 10.

上下一対のローラ４１は、各々の外周面が搬送装置１０により搬送される表面材３の側部３ｄの他面側に当接可能に構成されており、上下一対のローラ４１の各外周面が、搬送装置１０の左右方向外側へ向かうにつれて表面材３の他面側に近接した位置に設けられている。即ち、一対のローラ４１は、各外周面が搬送装置１０の左右方向における中央から外側（図３（ｂ）における右側から左側）へ向けて互いに近接するように傾斜させた状態で搬送装置１０に設けられている。 The pair of upper and lower rollers 41 are configured such that the outer peripheral surfaces of the pair of upper and lower rollers 41 can come into contact with the other surface side of the side portion 3 d of the surface material 3 conveyed by the conveying device 10. Further, it is provided at a position closer to the other surface side of the surface material 3 as it goes outward in the left-right direction of the transport device 10. That is, the pair of rollers 41 is placed on the transport device 10 in a state where the outer peripheral surfaces are inclined so as to approach each other from the center in the left-right direction of the transport device 10 toward the outside (right side to left side in FIG. 3B). Is provided.

芯材２及び表面材３が搬送装置１０の左右両側に配設された第１折り曲げ部４０の間を通過する際、一対の表面材３のそれぞれの側部３ｄの他面側に上下一対のローラ４２の外周面が当接し、一対の表面材３が第１溝部３ａに沿って互いに近接する側へ折り曲げられる。 When the core material 2 and the surface material 3 pass between the first bent portions 40 disposed on both the left and right sides of the conveying device 10, a pair of upper and lower sides is formed on the other surface side of each side portion 3 d of the pair of surface materials 3. The outer peripheral surface of the roller 42 abuts, and the pair of surface materials 3 are bent toward the side close to each other along the first groove portion 3a.

ここで、第１折り曲げ部４０は、搬送装置１０の左右両側それぞれに、上下一対のローラ４１が前後方向に沿って４組ずつ配設され、左右両側に配設された上下一対のローラ４１が、後方側に配設されるものほど離間間隔が狭くなるように左右方向内側へ寄せて配設されている。 Here, in the first bending portion 40, four pairs of upper and lower rollers 41 are arranged along the front-rear direction on each of the left and right sides of the conveying device 10, and the pair of upper and lower rollers 41 arranged on the left and right sides are provided. The one arranged closer to the rear side is arranged closer to the inner side in the left-right direction so that the separation interval becomes narrower.

これにより、表面材３の長手方向（図３（ａ）上下方向）全体において表面材３を第１溝部３ａに沿って確実に折り曲げることができる。 Thereby, the surface material 3 can be reliably bent along the 1st groove part 3a in the longitudinal direction (FIG. 3 (a) up-down direction) of the surface material 3 whole.

即ち、左右両側に配設された第１折り曲げ部４０の間に、表面材３の先端部分（搬送装置１０上に配置された状態における前端部分）が進入すると、表面材３の先端部分に位置する側部３ｄが上下一対のローラ４１のローラ外周面４１ａに当接し、表面材３の先端部分が第１溝部３ａに沿って折り曲げられる。 That is, when the front end portion of the surface material 3 (the front end portion in a state of being disposed on the transport device 10) enters between the first bent portions 40 disposed on the left and right sides, the surface material 3 is positioned at the front end portion. The side portion 3d to be in contact with the roller outer peripheral surface 41a of the pair of upper and lower rollers 41, and the tip portion of the surface material 3 is bent along the first groove portion 3a.

ここで、１組の上下一対のローラ４１により表面材３の先端部分を第１溝部３ａに沿って所定の角度まで折り曲げると、表面材３の先端部分よりも後方側、即ち、未だローラ外周面４１ａに当接していない部分も、表面材３の先端部分に追随して大きく折り曲げられる。 Here, when the front end portion of the surface material 3 is bent to a predetermined angle along the first groove portion 3a by a pair of upper and lower rollers 41, the rear side of the front end portion of the surface material 3, that is, still the roller outer peripheral surface The portion that is not in contact with 41 a is also bent greatly following the tip portion of the surface material 3.

そのため、表面材３の先端部分よりも後方側では、表面材３を第１溝部３ａに沿って十分に折り曲げることができず、左右両側に配設された第１折り曲げ部４０の間を通過した後に、表面材３が折れ曲がる前の状態（側部３ｄの他面側が中央部３ｃの他面側と面一となった状態）へ戻ろうと反発する力が大きくなる。 Therefore, on the rear side of the front end portion of the surface material 3, the surface material 3 cannot be sufficiently bent along the first groove portion 3a, and has passed between the first bent portions 40 disposed on the left and right sides. Later, when the surface material 3 is bent (the other surface side of the side portion 3d is flush with the other surface side of the central portion 3c), the repulsive force increases.

その結果、表面材３が第１折り曲げ部４０の後方に配設された第２折り曲げ部５０及び押し込み部６０（図１参照）に搬入される際に、側部３ｄの中央部３ｃに対する折り曲げ角度が不十分となり、埋没部３ｅを芯材２の凹部２ｃに埋没されないという不具合が生じやすくなる。 As a result, when the surface material 3 is carried into the second bent portion 50 and the push-in portion 60 (see FIG. 1) disposed behind the first bent portion 40, the bending angle with respect to the central portion 3c of the side portion 3d. Becomes insufficient, and the inconvenience that the buried portion 3e is not buried in the concave portion 2c of the core material 2 is likely to occur.

これに対し、第１折り曲げ部４０では、上下一対のローラ４１が前後方向に沿って複数配設されると共に、それら上下一対のローラ４１が、後方に位置するものほど左右方向内側へ寄せて配設されているので、表面材３を第１溝部３ａに沿って徐々に折り曲げることができる。これにより、表面材３の先端部分よりも後方側においても、表面材３を第１溝部３ａに沿って確実に折り曲げることができるので、第１折り曲げ部４０を通過した後に第１溝部３ａに沿って折り曲げられた表面材３が、折り曲げられる前の状態に戻ろうと反発する力を低減させることができる。 On the other hand, in the first bent portion 40, a plurality of pairs of upper and lower rollers 41 are arranged along the front-rear direction, and the pair of upper and lower rollers 41 that are located rearward are arranged closer to the inner side in the left-right direction. Since it is provided, the surface material 3 can be gradually bent along the first groove 3a. Thereby, since the surface material 3 can be reliably bent along the first groove portion 3a also on the rear side of the tip portion of the surface material 3, it passes along the first groove portion 3a after passing through the first bent portion 40. The surface material 3 bent in this manner can reduce the repulsive force to return to the state before being bent.

従って、側部３ｄを中央部３ｃに対して所定の角度まで折り曲げた状態で、第２折り曲げ部５０及び押し込み部６０へ搬送することができるので、埋没部３ｅを芯材２の凹部２ｃに埋没させる際の回避しやすくすることができる。 Accordingly, since the side portion 3d can be conveyed to the second bent portion 50 and the pushing portion 60 in a state where the side portion 3d is bent to a predetermined angle with respect to the central portion 3c, the buried portion 3e is buried in the concave portion 2c of the core material 2. It can be made easier to avoid.

なお、前後方向に沿って複数配設される上下一対のローラ４１のうち、前方側に位置するローラ４１は、表面材３の埋没部３ｅのみに当接するため、表面材３が第２溝部３ｂに沿って折れ曲がる場合がある。しかしながら、後方側に位置する上下一対のローラ４１が側部３ｄに当接することで、表面材３が第１折り曲げ部４０を通過した後の状態では、側部３ｄの中央部３ｃに対する折り曲げ角度が所定の角度となるように表面材３を第１溝部３ａに沿って確実に折り曲げることができる。 Of the pair of upper and lower rollers 41 arranged in the front-rear direction, the roller 41 positioned on the front side contacts only the buried portion 3e of the surface material 3, so that the surface material 3 is the second groove portion 3b. May bend along. However, when the pair of upper and lower rollers 41 located on the rear side abut on the side portion 3d, the bending angle of the side portion 3d with respect to the central portion 3c is increased after the surface material 3 has passed through the first bending portion 40. The surface material 3 can be reliably bent along the first groove 3a so as to have a predetermined angle.

また、第１折り曲げ部４０は、搬送装置１０に上下一対のローラ４１が回転可能に保持されているので、側部３ｄにローラ４１の外周面が当接することにより側部３ｄの他面側が傷つくことを回避しやすくすることができる。 Further, since the pair of upper and lower rollers 41 is rotatably held by the transport device 10 in the first bent portion 40, the other surface side of the side portion 3d is damaged when the outer peripheral surface of the roller 41 contacts the side portion 3d. This can be easily avoided.

次に、図４から図６を参照して、第２折り曲げ部５０について説明する。図４（ａ）は、図１のＩＶａ部分における搬送装置１０の部分拡大上面図であり、図４（ｂ）は、図４（ａ）のＩＶｂ方向から視た埋没部突合せ部５１の側面図である。図５（ａ）は、Ｗ状折り曲げ部５２の側面図であり、図５（ｂ）は、Ｗ状折り曲げ部５２の部分拡大側面図である。図６は、埋没部押え部５３の側面図である。図５及び図６は、搬送装置１０の左側に配設されたＷ状折り曲げ部５２又は埋没部押え部５３を後方側から視た図である。また、図４から図６では、搬送装置１０の左右両側に配設された埋没部突合せ部５１、Ｗ状折り曲げ部５２又は埋没部押え部５３の間を芯材２及び表面材３が通過する状態を模式的に図示している。さらに、図４（ａ）では、図面を簡素化して簡略に説明するため、第１溝部３ａ及び第２溝部３ｂの位置を破線で模式的に図示している。 Next, the 2nd bending part 50 is demonstrated with reference to FIGS. 4A is a partially enlarged top view of the transfer device 10 in the IVa portion of FIG. 1, and FIG. 4B is a side view of the buried portion butting portion 51 viewed from the IVb direction of FIG. 4A. It is. FIG. 5A is a side view of the W-shaped bent portion 52, and FIG. 5B is a partially enlarged side view of the W-shaped bent portion 52. FIG. 6 is a side view of the buried portion pressing portion 53. 5 and 6 are views of the W-shaped bent portion 52 or the buried portion pressing portion 53 disposed on the left side of the transport apparatus 10 as viewed from the rear side. 4 to 6, the core material 2 and the surface material 3 pass between the buried portion abutting portions 51, the W-shaped bent portions 52, or the buried portion pressing portions 53 disposed on the left and right sides of the transport device 10. The state is schematically illustrated. Further, in FIG. 4 (a), the positions of the first groove portion 3a and the second groove portion 3b are schematically illustrated by broken lines in order to simplify and simplify the drawing.

図４に示すように、埋没部突合せ部５１は、搬送装置１０に回転可能に保持された車輪状の部位であり、埋没部突合せ部５１の回転軸が上下方向へ向けられている。 As shown in FIG. 4, the buried portion butting portion 51 is a wheel-like portion that is rotatably held by the transfer device 10, and the rotation axis of the buried portion butting portion 51 is directed in the vertical direction.

搬送装置１０の左右両側に配設された埋没部突合せ部５１の離間間隔は、表面材３の第１溝部３ａの離間間隔よりも広く、かつ、表面材３が第１溝部３ａに沿って折れ曲がる前の状態における第２溝部３ｂの離間間隔よりも狭くなるように設定されている。また、埋没部突合せ部５１の高さ位置は、埋没部突合せ部５１の外周面が搬送装置１０の左右両側に配設される埋没部突合せ部５１の間に搬送される表面材３の埋没部３ｅと当接可能な位置に配設されている。 The spacing interval of the buried portion butting portions 51 disposed on the left and right sides of the transport device 10 is wider than the spacing interval of the first groove portion 3a of the surface material 3, and the surface material 3 bends along the first groove portion 3a. It is set to be narrower than the separation interval of the second groove 3b in the previous state. Further, the height position of the buried portion butting portion 51 is set such that the outer peripheral surface of the buried portion butting portion 51 is buried between the buried portion butting portions 51 arranged on the left and right sides of the conveying device 10. It is arranged at a position where it can come into contact with 3e.

搬送装置１０の左右両側に配置された埋没部突合せ部５１の間を芯材２及び表面材３が通過する際、埋没部突合せ部５１の外周面が表面材３の埋没部３ｅの他面側に当接する。これにより、表面材３が第２溝部３ｂに沿って折り曲げられ、一対の表面材３の各々の埋没部３ｅの端部どうし、即ち、表面材３の幅方向（図４左右方向）における端部どうしが互いに突き合わされる。 When the core material 2 and the surface material 3 pass between the buried portion butting portions 51 disposed on the left and right sides of the transport device 10, the outer peripheral surface of the buried portion butting portion 51 is the other surface side of the buried portion 3 e of the surface material 3. Abut. Thereby, the surface material 3 is bent along the second groove portion 3b, and the end portions of the respective embedded portions 3e of the pair of surface materials 3, that is, the end portions of the surface material 3 in the width direction (left-right direction in FIG. 4). The two face each other.

図５に示すように、Ｗ状折り曲げ部５２は、搬送装置１０に回転可能に保持された車輪状の部位であり、Ｗ状折り曲げ部５２の回転軸が上下方向へ向けられている。 As shown in FIG. 5, the W-shaped bent portion 52 is a wheel-shaped portion that is rotatably held by the transport device 10, and the rotation axis of the W-shaped bent portion 52 is directed in the vertical direction.

Ｗ状折り曲げ部５２は、その回転軸方向（図５上下方向）における両端側に位置し回転軸方向外側から中央へ向かうにつれて径方向寸法が小さくなるテーパ状に形成された一対の側部当接部５２ａと、それら一対の側部当接部５２ａの間に位置し回転軸方向における中央から外側へ向かうにつれて径方向寸法が小さくなるテーパ状に形成された一対の埋没部当接部５２ｂとを備えている。Ｗ状折り曲げ部５２は、一対の埋没部当接部５２ｂどうしが、それらの外径が最大となる部分で互いに連設して形成されると共に、埋没部当接部５２ｂの外径が最少となる部分に側部当接部５２ａの外径が最少となる部分が連設して形成されている。これにより、Ｗ状折り曲げ部５２は回転軸方向において対称に形成され、Ｗ状折り曲げ部５２の外周面が断面視略Ｗ字状に形成されている。 The W-shaped bent portion 52 is located on both ends in the rotation axis direction (vertical direction in FIG. 5) and has a pair of side contact portions formed in a tapered shape whose radial dimension decreases from the outer side toward the center in the rotation axis direction. Part 52a and a pair of buried part contact parts 52b formed between the pair of side part contact parts 52a and formed in a tapered shape in which the radial dimension decreases from the center to the outside in the rotation axis direction. I have. The W-shaped bent portion 52 is formed such that a pair of buried portion abutting portions 52b are connected to each other at a portion where the outer diameter is maximum, and the outer diameter of the buried portion abutting portion 52b is the smallest. The portion where the outer diameter of the side contact portion 52a is minimized is formed continuously with this portion. Thereby, the W-shaped bent portion 52 is formed symmetrically in the rotation axis direction, and the outer peripheral surface of the W-shaped bent portion 52 is formed in a substantially W shape in cross section.

Ｗ状押し込み部５２は、その回転軸方向中央部分（埋没部当接部５２ｂの最も外径が大きい部分どうしが連設する部分）が、埋没部突合せ部５１（図４参照）の外周面よりも左右方向中央側（図５右側）へ寄せた位置であって、左右両側に配設された埋没部突合せ部５１の離間間隔が、表面材３の第１溝部３ａの離間間隔よりも広く、かつ、表面材３が第１溝部３ａに沿って折れ曲がる前の状態における第２溝部３ｂの離間間隔よりも狭くなる位置に配設されている。また、Ｗ状押し込み部５２は、回転軸方向中央部分が、搬送装置１０上を芯材２及び表面材３が搬送される際に芯材２の厚さ方向（図５上下方向）中央部分が通過する高さ位置に配設されている。 The W-shaped push-in portion 52 has a central portion in the rotation axis direction (a portion where the portions having the largest outer diameter of the buried portion abutting portion 52b are connected to each other) from the outer peripheral surface of the buried portion butting portion 51 (see FIG. 4). Is also a position close to the center in the left-right direction (right side in FIG. 5), and the spacing between the buried portion butting portions 51 disposed on both the left and right sides is wider than the spacing between the first grooves 3a of the surface material 3, And it is arrange | positioned in the position where the surface material 3 becomes narrower than the separation interval of the 2nd groove part 3b in the state before bending along the 1st groove part 3a. Further, the central portion of the W-shaped push-in portion 52 in the rotational axis direction has a central portion in the thickness direction (vertical direction in FIG. 5) of the core material 2 when the core material 2 and the surface material 3 are conveyed on the conveying device 10. It is arranged at a height position where it passes.

搬送装置１０の左右両側に配設されたＷ状折り曲げ部５２の間を芯材２及び表面材３が通過する際、側部当接部５２ａの外周面が表面材３の側部３ｄの他面側に、埋没部当接部５２ｂの外周面が埋没部３ｅの他面側にそれぞれ当接する。このとき、表面材３は、側部３ｄの他面側を側部当接部５２ａの外周面に支持しつつ、Ｗ状折り曲げ部５２の外周面形状に倣って折り曲げることができる。即ち、一対の表面材３が互いに離間する方向へ変位することを回避できる。 When the core material 2 and the surface material 3 pass between the W-shaped bent portions 52 disposed on the left and right sides of the conveying device 10, the outer peripheral surface of the side contact portion 52 a is in addition to the side portion 3 d of the surface material 3. On the surface side, the outer peripheral surface of the buried portion abutting portion 52b abuts on the other surface side of the buried portion 3e. At this time, the surface material 3 can be bent following the outer peripheral surface shape of the W-shaped bent portion 52 while supporting the other surface side of the side portion 3d on the outer peripheral surface of the side contact portion 52a. That is, it is possible to avoid displacement of the pair of surface materials 3 in a direction away from each other.

ここで、表面材３を第２溝部３ｂに沿って折り曲げる際、側部３ｄを支持しないまま埋没部３ｅを芯材２の端面部２ｂ側へ押し込むだけでは、上下方向において対向する一対の側部３ｄが互いに離間する方向へ逃げるように変位しようとするため、埋没部３ｅを端面部２ｂ側へ押し込むことができず、埋没部３ｅを芯材２の凹部２ｃへ埋没させる際に不具合が生じやすくなる。 Here, when the surface material 3 is bent along the second groove portion 3b, a pair of side portions facing each other in the up-down direction simply by pushing the buried portion 3e toward the end surface portion 2b side of the core material 2 without supporting the side portion 3d. Since the 3d tends to be displaced so as to escape in the direction away from each other, the buried portion 3e cannot be pushed toward the end surface portion 2b, and a problem is likely to occur when the buried portion 3e is buried in the recessed portion 2c of the core member 2. Become.

これに対し、Ｗ状折り曲げ部５２は、側部当接部５２ａの外周面を側部３ｄの他面側に当接させることで、一対の表面材３が第１溝部３ａに沿って互いに離間する方向へ変位することを規制できる。これにより、側部３ｄの中央部３ｃに対する折り曲げ角度を一定に保持した状態で、表面材３を第２溝部３ｂに沿って更に折り曲げることができる。よって、一対の表面材３の埋没部３ｅが互いに突き合わされた状態を維持したまま、埋没部３ｅを第２溝部３ｂよりも芯材２の端面部２ｂに対してより近接した位置まで押し込むことができる。 On the other hand, the W-shaped bent portion 52 causes the pair of surface materials 3 to be separated from each other along the first groove portion 3a by bringing the outer peripheral surface of the side contact portion 52a into contact with the other surface side of the side portion 3d. It is possible to regulate displacement in the direction of movement. Thereby, the surface material 3 can be further bent along the second groove portion 3b in a state where the bending angle of the side portion 3d with respect to the central portion 3c is kept constant. Therefore, the embedded portion 3e can be pushed to a position closer to the end surface portion 2b of the core material 2 than the second groove portion 3b while maintaining the state in which the embedded portions 3e of the pair of surface materials 3 are abutted with each other. it can.

なお、請求項４記載の「一対の側部当接部および一対の埋没部当接部が連設されることで外周面が断面視略Ｗ字状に形成された」とは、側部当接部の外周面とその側部当接部に隣接する埋没部当接部の外周面とが互いに対向するように形成されていることを意味するものである。即ち、側部当接部の外周面と埋没部当接部の外周面との連設部分がＶ字状に連続して形成されているものに限定されるものではなく、側部当接部の外周面と埋没部当接部５３の外周面との連設部分が円弧状に形成されているものや、テーパ状に形成された側部当接部と埋没部当接部とが円柱状の円柱部を介して連設されているもの等も含まれる。 Note that “the pair of side abutment portions and the pair of buried portion abutment portions are connected to each other so that the outer peripheral surface is formed in a substantially W shape in a cross-sectional view” It means that the outer peripheral surface of the contact portion and the outer peripheral surface of the buried portion contact portion adjacent to the side contact portion are formed so as to face each other. In other words, the side contact portion is not limited to the one where the outer peripheral surface of the side contact portion and the outer peripheral surface of the buried portion contact portion are continuously formed in a V shape. The connecting portion between the outer peripheral surface of the inner surface and the outer peripheral surface of the buried portion contact portion 53 is formed in an arc shape, or the side contact portion and the buried portion contact portion formed in a tapered shape are cylindrical. The thing etc. which are connected through the cylindrical part of this are included.

図６に示すように、埋没部押え部５３は、搬送装置１０に回転可能に保持された略円板状の部位であり、埋没部押え部５３の回転軸が上下方向へ向けられている。 As shown in FIG. 6, the buried portion pressing portion 53 is a substantially disk-shaped portion that is rotatably held by the transport device 10, and the rotation axis of the buried portion holding portion 53 is directed in the vertical direction.

搬送装置１０の左右両側に配設された埋没部押え部５３の離間間隔は、Ｗ状折り曲げ部５２の埋没部当接部５２ｂ（図５参照）の最も外径が大きい部分どうしの離間間隔と略同等に設定されると共に、搬送装置１０上を芯材２及び表面材３が搬送される際に芯材２の厚さ方向（図６上下方向）中央部分が通過する高さ位置に埋没部押え５３が配設されている。 The spacing between the buried portion pressing portions 53 disposed on the left and right sides of the transfer device 10 is the spacing between the portions with the largest outer diameter of the buried portion abutting portion 52b (see FIG. 5) of the W-shaped bent portion 52. While being set to be substantially the same, the buried portion is at a height position through which the central portion in the thickness direction (vertical direction in FIG. 6) of the core material 2 passes when the core material 2 and the surface material 3 are conveyed on the conveying device 10. A presser 53 is provided.

搬送装置１０の左右両側に配置された埋没部押え部５３の間に芯材２及び表面材３が通過する際、埋没部押え部５３の外周面が一対の表面材３の各々の埋没部３ｅの外周面に当接する。 When the core material 2 and the surface material 3 pass between the buried portion pressing portions 53 disposed on the left and right sides of the transfer device 10, the outer peripheral surface of the buried portion holding portion 53 is the respective buried portion 3 e of the pair of surface materials 3. It abuts on the outer peripheral surface.

埋没部３ｅを埋没部押え部５３の外周面により押さえることで、表面材３が第１溝部３ａ又は第２溝部３ｂに沿って他面側（一対の表面材３が互いに離間する方向）へ曲がろうとすること、即ち、芯材２の端面部２ｂに近接した位置へ押し込まれた埋没部３ｅが、Ｗ状折り曲げ部５２によって折り曲げられる前の状態に戻ろうとすることを規制することができる。 By pressing the buried portion 3e with the outer peripheral surface of the buried portion pressing portion 53, the surface material 3 is bent along the first groove portion 3a or the second groove portion 3b to the other surface side (the direction in which the pair of surface materials 3 are separated from each other). That is, it is possible to prevent the buried portion 3e pushed into a position close to the end surface portion 2b of the core member 2 from returning to the state before being bent by the W-shaped bent portion 52.

次に、図７を参照して、押し込み部６０について説明する。図７（ａ）は、図１のＶＩＩａ部分における搬送装置１０の部分拡大上面図であり、図７（ｂ）は、図７（ａ）のＶＩＩｂ方向から視た押し込み部６０の側面図である。なお、図７（ａ）及び図７（ｂ）では、搬送装置１０の左右両側に配設された押し込み部６０の間を芯材２及び表面材３が通過する状態を模式的に図示している。 Next, the push-in part 60 will be described with reference to FIG. FIG. 7A is a partially enlarged top view of the transfer device 10 in the VIIa portion of FIG. 1, and FIG. 7B is a side view of the pushing portion 60 viewed from the VIIb direction of FIG. 7A. . 7A and 7B schematically illustrate a state in which the core material 2 and the surface material 3 pass between the push-in portions 60 disposed on the left and right sides of the transport device 10. Yes.

図７に示すように、押し込み部６０は、搬送装置１０に回転可能に保持された車輪状の部位であり、押し込み部６０の回転軸が上下方向へ向けられている。搬送装置１０の左右両側に配設された押し込み部６０の離間間隔は、表面材３の中央部３ｃの幅寸法と同等に設定されている。 As shown in FIG. 7, the push-in part 60 is a wheel-shaped part that is rotatably held by the transport device 10, and the rotation axis of the push-in part 60 is directed in the vertical direction. The spacing between the push-in portions 60 disposed on the left and right sides of the transport device 10 is set to be equal to the width dimension of the central portion 3 c of the surface material 3.

搬送装置１０の左右両側に配設される押し込み部６０の間を芯材２及び表面材３が通過する際、押し込み部６０の外周面に表面材３の側部３ｄが当接することで、側部３ｄ及び埋没部３ｅが芯材２の端部２ｂ側へ押し込まれ、埋没部３ｅが凹部２ｃの内部に埋没される。 When the core material 2 and the surface material 3 pass between the pushing portions 60 disposed on the left and right sides of the conveying device 10, the side portion 3 d of the surface material 3 comes into contact with the outer peripheral surface of the pushing portion 60, thereby The portion 3d and the buried portion 3e are pushed into the end 2b side of the core material 2, and the buried portion 3e is buried inside the recess 2c.

ここで、表面材３を第１溝部３ａ及び第２溝部３ｂに沿って折り曲げるにあたり、先に第２溝部３ｂに沿って表面材３を折り曲げた後に第１溝部３ａに沿って表面材３を折り曲げる場合、一対の表面材３の埋没部３ｅどうしを突き合わせる際に不具合が生じるおそれがある。 Here, when the surface material 3 is folded along the first groove portion 3a and the second groove portion 3b, the surface material 3 is first folded along the second groove portion 3b, and then the surface material 3 is folded along the first groove portion 3a. In this case, there is a possibility that a problem may occur when the buried portions 3e of the pair of surface materials 3 are brought into contact with each other.

即ち、表面材３を第２溝部３ｂに沿って折り曲げるようとすると、表面材３が第２溝部３ｂに沿ってだけでなく、第１溝部３ａに沿って折れ曲がろうとする。このとき、表面材３が第１溝部３ａに沿って折り曲げられると、その分、埋没部３ｅの側部３ｄに対する折り曲げ角度が小さくなる。これにより、一方の表面材３における埋没部３ｅの側部３ｄに対する折り曲げ角度と他方の表面材３における埋没部埋没部３ｅの側部３ｄに対する折り曲げ角度にばらつきが生じる。この状態で、表面材３を第１溝部３ａに沿って折り曲げたとしても、一対の表面材３の埋没部３ｅどうしを突き合わせることができず、埋没部３ｅが芯材２の凹部２ｃに埋没されないといった不具合が生じやすくなる。 That is, when the surface material 3 is to be bent along the second groove portion 3b, the surface material 3 tends to bend not only along the second groove portion 3b but also along the first groove portion 3a. At this time, when the surface material 3 is bent along the first groove portion 3a, the bending angle of the buried portion 3e with respect to the side portion 3d is reduced accordingly. As a result, the bending angle of the one surface material 3 with respect to the side portion 3d of the buried portion 3e and the bending angle of the other surface material 3 with respect to the side portion 3d of the buried portion buried portion 3e vary. Even if the surface material 3 is bent along the first groove 3a in this state, the buried portions 3e of the pair of surface materials 3 cannot be brought into contact with each other, and the buried portion 3e is buried in the recess 2c of the core material 2. Inconveniences such as failure to occur are likely to occur.

そのため、先に表面材３を第２溝部３ｂに沿って折り曲げた後、第１溝部３ａを折り曲げる場合には、表面材３が第１溝部３ａに沿って折れ曲がることを防止しつつ、表面材３を第２溝部３ｂに沿って折り曲げるために、側部３ｄの一面側を支持する部材を搬送装置に別途設けることにより不具合を回避する必要がある。 Therefore, when the first groove portion 3a is bent after the surface material 3 is first bent along the second groove portion 3b, the surface material 3 is prevented from being bent along the first groove portion 3a. In order to bend the wire along the second groove 3b, it is necessary to avoid a problem by separately providing a member for supporting one surface side of the side portion 3d in the transport device.

これに対し、扉製造装置１００は、先に第１折り曲げ部４０（図１参照）によって、中央部３ｃに対する側部３ｄの角度が所定の角度になるように表面材３を第１溝部３ａに沿って折り曲げた後、第２折り曲げ部５０（図１参照）によって表面材３を第２溝部３ｂに沿って折り曲げる。 On the other hand, the door manufacturing apparatus 100 uses the first bent portion 40 (see FIG. 1) to place the surface material 3 into the first groove portion 3a so that the angle of the side portion 3d with respect to the central portion 3c becomes a predetermined angle. After being bent along, the surface material 3 is bent along the second groove 3b by the second bent portion 50 (see FIG. 1).

従って、一対の表面材３は、第１折り曲げ部４０により第１溝部３ａに沿って側部３ｄが中央部３ｃに対して所定の角度まで折り曲げられた状態で、第２折り曲げ部５０により第２溝部３ｂに沿って埋没部３ｅが側部３ｄに対して折り曲げられた後、押し込み部６０により側部３ｄ及び埋没部３ｅを押し込むことができるので、一対の表面材３の各々の埋没部３ｅを凹部２ｃに埋没させやすくすることができる。よって、扉１の製造時において、一対の表面材３の双方の埋没部３ｅが凹部に埋没されないといった不具合を低減させることができる。 Therefore, the pair of surface materials 3 are secondly bent by the second bent portion 50 in a state where the side portion 3d is bent to the predetermined angle with respect to the central portion 3c along the first groove portion 3a by the first bent portion 40. After the buried portion 3e is bent with respect to the side portion 3d along the groove portion 3b, the side portion 3d and the buried portion 3e can be pushed by the push-in portion 60, so that each buried portion 3e of the pair of surface materials 3 is It can be made easy to be buried in the recess 2c. Therefore, at the time of manufacturing the door 1, it is possible to reduce a problem that both the buried portions 3e of the pair of surface materials 3 are not buried in the concave portions.

また、表面材３を第２溝部３ｂに沿って折り曲げた後に第１溝部３ａに沿って折り曲げる場合のように、側部３ｄの一面側を支持する部材を搬送装置１０に設けることを不要とすることができるので、巻き込み部材２０の構成を簡素化でき、その結果、扉製造装置１００の製造コストを抑制できる。 Further, it is not necessary to provide the transport device 10 with a member that supports one surface side of the side portion 3d as in the case where the surface material 3 is bent along the second groove portion 3b and then bent along the first groove portion 3a. Therefore, the configuration of the entraining member 20 can be simplified, and as a result, the manufacturing cost of the door manufacturing apparatus 100 can be suppressed.

次に、第２実施の形態について説明する。第１実施の形態では、巻き付け部材２０の第１折り曲げ部４０が車輪状に形成された上下一対のローラ４１が、前後方向に複数配設される場合について説明したが、第２実施の形態では、巻き付け部材２２０の第１折り曲げ部２４０が板状に形成されている。なお、上記した第１実施の形態と同一の部分については同一の符号を付して、その説明を省略する。 Next, a second embodiment will be described. In 1st Embodiment, although the 1st bending part 40 of the winding member 20 demonstrated the case where two or more pairs of the upper and lower rollers 41 formed in the shape of a wheel were arrange | positioned in the front-back direction, in 2nd Embodiment. The first bent portion 240 of the winding member 220 is formed in a plate shape. In addition, the same code | symbol is attached | subjected about the same part as above-mentioned 1st Embodiment, and the description is abbreviate | omitted.

図８は、第２実施の形態における扉製造装置２００の上面図である。図９（ａ）は、図８のＩＸａ−ＩＸａ線における第１折り曲げ部２４０の断面図であり、図９（ｂ）は、図８のＩＸｂ−ＩＸｂ線における第１折り曲げ部２４０の断面図である。なお、図８では、図面を簡素化して簡略に説明するため、第１溝部３ａ及び第２溝部３ｂの位置を破線で模式的に図示している。また、図９（ａ）及び図９（ｂ）では、搬送装置１０の左右両側に配設された第１折り曲げ部２４０の間を芯材２及び表面材３が通過する状態を模式的に図示しており、第１折り曲げ部２４０のみを断面視している。 FIG. 8 is a top view of the door manufacturing apparatus 200 according to the second embodiment. 9A is a cross-sectional view of the first bent portion 240 along the line IXa-IXa in FIG. 8, and FIG. 9B is a cross-sectional view of the first bent portion 240 along the line IXb-IXb in FIG. is there. In FIG. 8, the positions of the first groove portion 3 a and the second groove portion 3 b are schematically illustrated by broken lines in order to simplify and simplify the drawing. 9A and 9B schematically show a state in which the core material 2 and the surface material 3 pass between the first bent portions 240 disposed on the left and right sides of the transport device 10. FIG. Only the first bent portion 240 is shown in cross section.

図８に示すように、扉製造装置２００は、位置決め部３０の後方側に配設される第１折り曲げ部２４０を備え、その第１折り曲げ部２４０の後方側に第２折り曲げ部５０が配設されている。 As shown in FIG. 8, the door manufacturing apparatus 200 includes a first bent portion 240 disposed on the rear side of the positioning portion 30, and the second bent portion 50 is disposed on the rear side of the first bent portion 240. Has been.

図９に示すように、第１折り曲げ部２４０は、搬送装置１０に支持される板状の部位であり、上下方向に一対設けられている。 As shown in FIG. 9, the 1st bending part 240 is a plate-shaped site | part supported by the conveying apparatus 10, and a pair is provided in the up-down direction.

第１折り曲げ部２４０は、平面状に形成される平面部２４１を備えている。平面部２４１は、表面材３の側部３ｄの他面側に当接される部位である。第１折り曲げ部２４０は、平面部２４１が搬送装置１０により搬送される一対の表面材３の他面側に対向するように配設されており、平面部２４１は、前後方向に垂直な断面視において、平面部２４１が中央から左右方向外側（図９（ｂ）右側から左側）へ向かうにつれて表面材３に対して近接するように傾斜している。また、第１折り曲げ部２４０は、前方から後方へ向かうにつれて左右方向中央側へ寄せて配置されることで、搬送装置１０の左右両側に配置された第１折り曲げ部２４０の平面部２４１の離間間隔が、前方から後方へ向かうにつれて狭くなっている。 The 1st bending part 240 is provided with the plane part 241 formed in planar shape. The flat surface portion 241 is a portion that comes into contact with the other surface side of the side portion 3 d of the surface material 3. The first bent portion 240 is disposed so that the flat surface portion 241 faces the other surface side of the pair of surface materials 3 conveyed by the conveying device 10, and the flat surface portion 241 is a cross-sectional view perpendicular to the front-rear direction. , The flat surface portion 241 is inclined so as to approach the surface material 3 from the center toward the outside in the left-right direction (from the right side to the left side in FIG. 9B). In addition, the first bent portion 240 is disposed closer to the left and right center as it moves from the front to the rear, so that the spacing between the flat portions 241 of the first bent portion 240 disposed on the left and right sides of the transport device 10 is increased. However, it narrows from the front to the rear.

搬送装置１０の左右両側に配設された第１折り曲げ部２４０の間を通過する際、表面材３の他面側に第１折り曲げ部２４０の平面部２４１が当接し、表面材３は第１溝部３ａに沿って折り曲げられる。 When passing between the first bent portions 240 arranged on the left and right sides of the conveying device 10, the flat surface portion 241 of the first bent portion 240 abuts on the other surface side of the surface material 3, and the surface material 3 is the first one. It is bent along the groove 3a.

このとき、搬送装置１０の左右両側へ配置された第１折り曲げ部２４０は、平面部２４１の離間間隔が前方から後方へ向かうにつれて狭くなっているので、表面材３を第１溝部３ａに沿って徐々に折り曲げることができる。これにより、表面材３の先端部分よりも後方側部分においても、第１折り曲げ部２４０により表面材３を第１溝部３ａに沿って確実に折り曲げることができ、一旦第１溝部３ａに沿って折れ曲がった表面材３が元の状態に戻ろうとすることを抑制できる。その結果、埋没部３ｅを芯材２の凹部２ｃに埋没させる際の不具合を回避しやすくすることができる。 At this time, the first bent portions 240 arranged on the left and right sides of the transport device 10 are narrower as the spacing between the flat portions 241 is increased from the front toward the rear, so that the surface material 3 extends along the first grooves 3a. Can be bent gradually. Accordingly, the surface material 3 can be reliably bent along the first groove portion 3a by the first bent portion 240 at the rear side portion of the front end portion of the surface material 3 and once bent along the first groove portion 3a. The surface material 3 can be prevented from returning to its original state. As a result, it is possible to easily avoid a problem when the buried portion 3e is buried in the recessed portion 2c of the core material 2.

なお、第１折り曲げ部２４０の前方部分では、表面材３の埋没部３ｅのみに平面部２４１が当接するため、表面材３が第２溝部３ｂに沿って折れ曲がる場合がある。しかしながら、第１折り曲げ部２４０の後方部分が側部３ｄの他面側に当接することで、側部３ｄの中央部３ｃに対する折り曲げ角度が所定の角度となるように表面材３を第１溝部３ａに沿って確実に折り曲げることができる。 In addition, in the front part of the 1st bending part 240, since the plane part 241 contact | abuts only to the burying part 3e of the surface material 3, the surface material 3 may bend along the 2nd groove part 3b. However, when the rear portion of the first bent portion 240 is in contact with the other surface side of the side portion 3d, the surface material 3 is moved to the first groove portion 3a so that the bent angle with respect to the central portion 3c of the side portion 3d becomes a predetermined angle. Can be reliably bent along.

以上、実施の形態に基づき、本発明を実施したが、必ずしもこれに限定されるものではなく、本発明の趣旨を逸脱しない範囲内で種々の改良変形が可能であることは容易に推察できるものである。 As mentioned above, although this invention was implemented based on embodiment, it is not necessarily limited to this, It can be guessed easily that various improvement deformation | transformation are possible within the range which does not deviate from the meaning of this invention. It is.

By disposing a plurality of W-shaped bent portions 52 and buried portion pressing portions 53, the surface material 3 can be reliably bent along the first groove portions 3a and the second groove portions 3b.

上記各実施の形態では、位置決め部３０、埋没部突合せ部５１、Ｗ状折り曲げ部５２、埋没部押え部５３及び押し込み部６０が円板状または車輪状に形成され、それらの外周面が芯材２又は表面材３に当接される場合について説明したが、必ずしもこれに限られるものではなく、位置決め部３０、埋没部突合せ部５１、Ｗ状折り曲げ部５２、埋没部押え部５３及び押し込み部６０が平面状に形成された部位を備え、その平面状に形成された部位を芯材２又は表面材３に当接させてもよい。 In each of the above-described embodiments, the positioning portion 30, the buried portion butting portion 51, the W-shaped bent portion 52, the buried portion pressing portion 53, and the pushing portion 60 are formed in a disk shape or a wheel shape, and their outer peripheral surfaces are core materials. However, the present invention is not necessarily limited to this, and the positioning portion 30, the buried portion butting portion 51, the W-shaped bent portion 52, the buried portion pressing portion 53, and the pushing portion 60 are not necessarily limited thereto. May be provided with a portion formed in a planar shape, and the portion formed in the planar shape may be brought into contact with the core material 2 or the surface material 3.

上記第１実施の形態では、第１折り曲げ部４０の上下一対のローラ４１が前後方向に複数配設される場合について説明したが、必ずしもこれに限られるものではなく、上下一対のローラ４１は搬送装置１０の左右両側に少なくとも１つ配設されていればよい。この場合、搬送装置１０の左右両側に配設された上下一対のローラ４１の離間間隔を調整し、少なくとも１組の上下一対のローラ４１が側部３ｄに当接可能に配置することで、表面材３が第１溝部３ａに沿って折れ曲がるようにすればよい。 In the first embodiment, the case where a plurality of pairs of upper and lower rollers 41 of the first bent portion 40 are arranged in the front-rear direction has been described. However, the present invention is not necessarily limited to this, and the pair of upper and lower rollers 41 are transported. It is sufficient that at least one device is disposed on each of the left and right sides of the device 10. In this case, the distance between the pair of upper and lower rollers 41 disposed on the left and right sides of the transport device 10 is adjusted, and at least one pair of the upper and lower pairs of rollers 41 is disposed so as to be in contact with the side portion 3d. What is necessary is just to make it the material 3 bend along the 1st groove part 3a.

上記第１実施の形態では、前後方向に複数配設された上下一対のローラ４１の離間間隔が、後方側に位置するものほど狭くなるように配設される場合について説明したが、必ずしもこれに限られるものではなく、前後方向に複数配設された上下一対のローラ４１の離間間隔が、すべて同等に設定されていてもよい。 In the first embodiment described above, a case has been described in which a plurality of upper and lower rollers 41 arranged in the front-rear direction are arranged so that the spacing between the rollers 41 is closer to the rear side. The spacing between the pair of upper and lower rollers 41 disposed in the front-rear direction is not limited and may be set to be equal.

上記第１実施の形態では、前後方向に複数配設された上下一対のローラ４１の回転軸がすべて同じ方向へ向けられている場合について説明したが、必ずしもこれに限られるものではなく、後方側に位置するものほど、上下一対のローラ４１の回転軸の傾斜角度を大きくしてもよい。これにより、表面材３を第１溝部３ａに沿って徐々に折り曲げることができる。 In the first embodiment, a case has been described in which the rotation axes of the pair of upper and lower rollers 41 disposed in the front-rear direction are all directed in the same direction. The tilt angle of the rotation axis of the pair of upper and lower rollers 41 may be increased as the position is located in the position. Thereby, the surface material 3 can be gradually bent along the 1st groove part 3a.

上記第１実施の形態では、第１折り曲げ部４０の上下一対のローラ４１が前後方向に沿って複数配設される場合について説明したが、必ずしもこれに限られるものではなく、複数配設される上下一対のローラ４１の一部を、上記第２実施の形態における第１折り曲げ部２４０と置き換えてもよい。例えば、上記第１実施の形態において前後方向に配設された４組の上下一対のローラ４１のうち、前方から数えて２番目および３番目に配設された上下一対のローラ４１の代わりに、上記第２実施の形態における第１折り曲げ部２４０を配設してもよい。 In the first embodiment, the case where a plurality of pairs of upper and lower rollers 41 of the first bent portion 40 are disposed along the front-rear direction has been described. However, the present invention is not necessarily limited to this, and a plurality of rollers 41 are disposed. A part of the pair of upper and lower rollers 41 may be replaced with the first bent portion 240 in the second embodiment.
