Description

本発明は、下面に接着剤層が設けられた加飾シートを真空状態で被着体に被着して加飾成形する、加飾シートによる加飾成形方法、及び仕上げ用冶具に関し、特に、加飾シートによる加飾成形後のシートの不要部分を除去する方法、及びこれに使用する冶具に関する。 The present invention, a decorative sheet provided with an adhesive layer on the lower surface is subjected to decorative molding by adhering to an adherend in a vacuum state, a decorative molding method by a decorative sheet, and a finishing jig, in particular, The present invention relates to a method for removing unnecessary parts of a sheet after decorative molding with a decorative sheet, and a jig used for this method.

自動車の車体のような大型の被着体に対して部分的なフィルム加飾を行う部分オーバーレイ方法として、上部開口した収容チャンバーと下部開口した上ボックスとを、加飾フィルムを挟んだ状態で上下に組み合わせて、ボックス空間と収容空間とが上下に連成した成形空間を密閉形成し、この成形空間内の上下の空間に瞬間的な圧力差を生じさせることで、成形空間内に収容した被着体Ｗの一部表面に加飾フィルムを減圧密着させるものが開示される（特許文献１）。 As a partial overlay method for partially decorating a large adherend such as a car body of an automobile, an accommodation chamber with an upper opening and an upper box with a lower opening are placed vertically with a decorative film sandwiched between them. In combination, the box space and the storage space are vertically connected to form a closed molding space, and an instantaneous pressure difference is generated between the upper and lower spaces in the molding space. A device is disclosed in which a decorative film is adhered under reduced pressure to a part of the surface of the dressing W (Patent Document 1).

また一方で、成形板材からなる大型の被着体においてはしばしば、成形面の裏側をロアパネルで補強し、アッパパネルとロアパネルとによって中空構造を形成したものが採用される。例えば自動車のフロントサスペンションメンバとして、アッパパネルとロアパネルとによって中空構造に形成され、横方向の各側部に前方のアーム取付け部と後方のアーム取付け部とを備えたものが開示される（特許文献２）。前記中空構造においては例えば、前方のアーム取付け部から前記後方のアーム取付け部へ実質的に直線状に伸びる縦壁を有しており、前記後方のアーム取付け部は、前記アッパパネルを横方向へ伸ばした部分と、前記ロアパネルに溶接され、横方向へ張り出されたブレースとによって形成される。 On the other hand, in the case of a large adherend made of a molded plate, a back panel of the molding surface is often reinforced with a lower panel, and a hollow structure is formed by the upper panel and the lower panel. For example, as a front suspension member of an automobile, there is disclosed a front suspension member formed in a hollow structure by an upper panel and a lower panel and provided with a front arm mounting portion and a rear arm mounting portion on each lateral side (Patent Document 2). ). In the hollow structure, for example, there is a vertical wall that extends substantially linearly from the front arm mounting portion to the rear arm mounting portion, and the rear arm mounting portion extends the upper panel in the lateral direction. And a brace welded to the lower panel and laterally overhanging.

しかしながら、成形板材が中空構造の一部を部分加飾成形範囲に含む場合には、加飾フィルムによって加飾成形する際、成形板材の裏側が瞬間的かつ急激に減圧されることで、中空構造が圧潰変形してしまう。すなわち、加飾フィルムによる加飾成形においては、加飾成形範囲の成形板材を収容する収容空間と、加飾フィルムを境とした収容空間上部の上ボックス空間とを等圧状態にしておき、この等圧状態から、収容空間内をボックス空間に対して大幅に減圧した減圧状態へと、急激に状態変移させる。この急激な状態変移の際に収容空間は瞬間的な減圧状態となるため、収容空間内に中空構造を有した被着体が収容される場合は、この中空構造が減圧状態変移によって圧潰するなど、減圧化による変形等の影響を受けてしてしまう。 However, when the molded plate material includes a part of the hollow structure in the partial decorative molding range, when the decorative film is subjected to decorative molding, the back side of the molded plate material is momentarily and rapidly depressurized, thereby forming a hollow structure. Will be crushed and deformed. That is, in the decorative molding with the decorative film, the accommodation space for accommodating the molding plate material in the decorative molding range and the upper box space of the accommodation space above the decorative film are kept in an equal pressure state, The state is rapidly changed from the isobaric state to a depressurized state in which the accommodation space is largely depressurized with respect to the box space. Since the accommodation space is momentarily depressurized during this rapid state transition, when the adherend having a hollow structure is accommodated in the accommodation space, the hollow structure is crushed by the depressurization state transition. However, it will be affected by the deformation due to the reduced pressure.

この減圧による影響を回避するため、収容空間のうち中空構造の部分を上ボックス空間と通気バイパスして、中空構造の内部だけ部分的に上ボックス空間と等圧状態を保つ対策も考えられる。このような通気バイパスによって中空構造の内部だけ部分的に等圧状態を保つためには、中空構造を気密状態に保ち、中空構造の部分だけを上ボックス空間と等圧制御する構造が必要となる。 In order to avoid the influence of this decompression, it is also possible to consider a measure in which the hollow structure portion of the accommodation space is bypassed to the upper box space by ventilation so that only the inside of the hollow structure maintains an equal pressure state with the upper box space. In order to maintain a partial isobaric condition only inside the hollow structure by such a ventilation bypass, it is necessary to have a structure that keeps the hollow structure airtight and controls only the hollow structure part with the upper box space at a constant pressure. ..

しかしながら、前記構造ないし被着方法では、開口部を有する被着体において、開口部を含んだ加飾成形部に加飾フィルムが被着成形された場合、開口部の加飾フィルムの不要部を除去するために、当該開口部に被着された加飾フィルムを事前にカットしたり、加飾成形部の裏側を向けたり、或いは裏側から加工することが必要であった。すなわち、開口部が立体形状からなる場合などにおいて、加飾成形部のうち開口部の加飾フィルムを除去するには、加飾フィルムの上側の一方からではなく裏側の他方からレーザー照射するという多方法のレーザー照射工程や、開口部に被着された加飾フィルムの大半を事前に破って取り除くような事前工程が必要となっていた。このため、開口部の加飾フィルムの加飾成形範囲の境界部を確実に、或いは迅速にレーザーカットすることが困難であった。 However, in the above-mentioned structure or deposition method, in the adherend having an opening, when the decorative film is adhered to the decorative molding portion including the opening, unnecessary portions of the decorative film in the opening are removed. In order to remove it, it was necessary to previously cut the decorative film adhered to the opening, or to orient the back side of the decorative molding portion, or to process from the back side. That is, in the case where the opening has a three-dimensional shape, in order to remove the decorative film in the opening of the decorative molding portion, laser irradiation is often performed from the other side of the decorative film, not from the upper side. The method requires a laser irradiation step and a preliminary step of breaking and removing most of the decorative film adhered to the opening. For this reason, it has been difficult to reliably or quickly laser cut the boundary portion of the decorative molding range of the decorative film in the opening.

そこで本発明では、開口部を有する被着体において、開口部を含んだ加飾成形部に加飾フィルムが被着成形された被着体において、開口部の加飾フィルムを事前にカットしたり、加飾成形部の裏側を向けたり、或いは裏側から加工することなく、加飾成形部の加飾フィルムの上側の一方から、開口部の加飾フィルムの加飾成形範囲の境界部を確実にかつ迅速にレーザーカットすることができる、被着体への加飾フィルムの加飾成形方法、及び加飾成形の仕上げ用冶具を提供することを課題とする。 Therefore, in the present invention, in the adherend having an opening, in the adherend in which the decorative film is adhered and molded in the decorative molding portion including the opening, the decorative film in the opening may be cut in advance. , Without facing the back side of the decorative molding portion or processing from the back side, from one of the upper side of the decorative film of the decorative molding portion, surely the boundary portion of the decorative molding range of the decorative film of the opening An object of the present invention is to provide a decorative molding method of a decorative film on an adherend and a jig for finishing the decorative molding, which can perform laser cutting rapidly.

Can be
(Decoration molding method) In the decoration molding method of Example 1 of the present invention, the decoration molding range (MA) of the enclosure space (C) is decorated by using the predetermined decoration molding finishing jig. It is a method of partially decoratively forming a film (F), including the following steps.
The enclosure frame body (33) is brought into contact with the upper part of the adherend (W) to enclose the decorative molding range (MA), and the adherend (W) and the enclosure frame body (33) are included in the lower box (1). ) Is stored in a state of storing,

The upper opening of the lower box (1) and the lower opening of the upper box (2) are opposed to each other, and the decorative film (F) is sandwiched between the lower opening and the upper opening to form the upper space (A) and the lower space. A first sealing step which is vertically coupled to form a sealed upper space (A) and a sealed lower space;
A first pressure adjusting step of bringing the sealed lower space and the sealed upper space (A) into a predetermined first pressure state of equal pressure with each other by the pressure control device;
In the lower space of the sealed state, the decorative film (F) or the holding frame (32) of the peripheral part thereof and the surrounding frame body (33) are brought into contact with each other, and sealed inside the frame of the surrounding frame body (33). A second sealing step of forming an enclosed space (C) in a state,
With the inside of the enclosed space (C) maintained at the first pressure state, the pressure control device controls the sealed lower space and the sealed upper space (A) excluding the enclosed space (C). And a second pressure adjusting step of instantaneously pressurizing from the depressurized state to bring them into a second pressure state of equal pressure to each other.

前記の第二密閉工程によれば、加飾成形範囲（ＭＡ）の加飾面のみを囲い枠で囲うことで、上部に加飾フィルム（Ｆ）が張設された密閉状態の囲い空間（Ｃ）を、第一圧力状態に制御された密閉状態の下空間内に形成することができる。前記の第二圧力調整工程によれば、密閉状態の囲い空間（Ｃ）内を第一圧力状態に維持した状態のまま、上空間（Ａ）内を瞬間的に加圧することで、上空間（Ａ）と囲い空間（Ｃ）の圧力差によって加飾成形範囲（ＭＡ）に瞬間的に加飾成形を行うことができる。また、前記の第二圧力調整工程によれば、上空間（Ａ）内と下空間内とを互いに等圧力のまま瞬間的に加圧することで、囲い空間（Ｃ）を除く下空間（Ｂ）内には圧力差による影響が生じない。 According to the second sealing step, by surrounding only the decorative surface of the decorative molding range (MA) with the surrounding frame, the decorative film (F) is stretched over the enclosed space (C). ) Can be formed in the closed lower space controlled to the first pressure state. According to the above-mentioned second pressure adjusting step, the upper space (A) is momentarily pressurized while the closed space (C) is maintained in the first pressure state, whereby the upper space ( The decorative molding can be instantaneously performed in the decorative molding area (MA) by the pressure difference between A) and the enclosed space (C). Further, according to the second pressure adjusting step, the upper space (A) and the lower space are instantaneously pressurized while maintaining equal pressure to each other, so that the lower space (B) excluding the enclosing space (C). There is no effect due to the pressure difference inside.

このように上空間（Ａ）と下空間の間の第三の密閉空間として、下空間内に囲い空間（Ｃ）を形成することにより、被着体（Ｗ）の加飾面の裏側に窪みや孔や隙間がある場合であっても、第二圧力工程による急激な圧力差による影響を受けることがない。
また、被着体（Ｗ）を受け冶具等で支える場合でも、被着体（Ｗ）の下面側を同じ圧力とするための導圧回路を設ける必要がなく、被着体（Ｗ）の減圧時の成形保持性能に拘らず、複雑な形状の被着体（Ｗ）であっても、比較的簡易な構造で確実に被着体（Ｗ）の部分加飾成形を行うことができる。例えば範囲の裏側に微細な穴ないし孔、溶接部、接着部、或いは内部空間が存在していた場合でも、被着面の部分加飾成形範囲（ＭＡ）において密閉状態の囲い空間（Ｃ）が形成されることで、被着体（Ｗ）の成形部分が変形したり欠損したりすることなく、また、圧力漏れが生じることもない。
（第一圧力工程、第二圧力調整工程）
前記第一圧力工程は、囲い空間（Ｃ）を除く密閉状態の下空間内及び密閉状態の上空間（Ａ）内を同時に吸引して、大気圧よりも減圧させた第一圧力状態とする工程であり、
前記第二圧力調整工程は、前記第一圧力調整工程で第一圧力状態とした、囲い空間（Ｃ）を除く密閉状態の下空間内及び密閉状態の上空間（Ａ）を、同時に大気圧に開放して、大気圧と等圧の第二圧力状態とする工程である。前記の工程であれば、圧力制御装置として少なくとも、上ボックス（２）及び下ボックス（１）に連通する連通管とこれに接続する減圧ポンプを有していればよく、簡易な機構をもって確実な圧力制御を行うことができる。
（囲い空間（Ｃ）の形成）
前記第一密閉工程は、横方向に拡げた加飾フィルム（Ｆ）の縁部を、上下移動可能な保持枠（３２）によって保持固定し、
前記上空間（Ａ）と下空間とを連成することで、加飾フィルム（Ｆ）を保持した保持枠（３２）を、前記下空間内ないし上空間（Ａ）内に収容するものであり、
前記第二密閉工程は、前記保持枠（３２）を下降させて、被着体（Ｗ）の加飾成形範囲（ＭＡ）を含む接触上面又は被着体（Ｗ）上に配置された囲い枠体（３３）の接触面と、前記保持枠（３２）の対向接触面と、を接触させることで、被着体（Ｗ）の加飾成形範囲（ＭＡ）の接触上面と、囲い枠体（３３）の枠内面と、加飾フィルム（Ｆ）の下面とによって囲まれた囲い空間（Ｃ）を形成するものである。 Thus, by forming the enclosed space (C) in the lower space as a third closed space between the upper space (A) and the lower space, a recess is formed on the back side of the decorative surface of the adherend (W). Even if there is a hole or a gap, it is not affected by the sudden pressure difference due to the second pressure step.
Further, even when the adherend (W) is supported by a jig or the like, it is not necessary to provide a pressure guiding circuit for keeping the lower surface side of the adherend (W) at the same pressure, and the pressure reduction of the adherend (W) is possible. Even if the adherend (W) has a complicated shape, the partial decorative molding of the adherend (W) can be surely performed with a relatively simple structure regardless of the molding holding performance. For example, even if there are fine holes or holes, welded portions, bonded portions, or internal spaces on the back side of the range, the enclosed space (C) in the sealed state in the partial decorative molding range (MA) of the adherend is By being formed, the molded part of the adherend (W) is not deformed or chipped, and pressure leakage does not occur.
(First pressure step, second pressure adjustment step)
The first pressure step is a step of simultaneously sucking the lower space of the sealed state excluding the enclosed space (C) and the upper space (A) of the sealed state to a first pressure state in which the pressure is reduced from atmospheric pressure. And
In the second pressure adjusting step, the inside of the closed lower space and the closed upper space (A) excluding the enclosed space (C) and the closed upper space (A) which are in the first pressure state in the first pressure adjusting step are simultaneously brought to atmospheric pressure. This is a step of opening to a second pressure state that is equal to atmospheric pressure. In the above process, it is sufficient to have at least a communication pipe communicating with the upper box (2) and the lower box (1) and a decompression pump connected to the pressure control device as a pressure control device. Pressure control can be performed.
(Formation of enclosure space (C))
In the first sealing step, the edge portion of the decorative film (F) expanded in the lateral direction is held and fixed by a holding frame (32) that is vertically movable,
By connecting the upper space (A) and the lower space, the holding frame (32) holding the decorative film (F) is housed in the lower space or the upper space (A). ,
In the second sealing step, the holding frame (32) is moved down, and the contact upper surface including the decorative molding range (MA) of the adherend (W) or an enclosure frame arranged on the adherend (W). By bringing the contact surface of the body (33) into contact with the facing contact surface of the holding frame (32), the contact upper surface of the decorative molding range (MA) of the adherend (W) and the surrounding frame body ( The enclosure space (C) surrounded by the inner surface of the frame 33) and the lower surface of the decorative film (F) is formed.

前記第一密閉工程によれば、上下移動可能な保持枠（３２）を、予め上開口の上部近傍ないし下開口の下部近傍に配置しており、この保持枠（３２）によって保持した加飾フィルム（Ｆ）を、上下に密閉連成された上空間（Ａ）ないし下空間の内部に収容することとなる。この状態では下空間内に囲い空間（Ｃ）は形成されておらず、その後の第一圧力調整工程によって、下空間全体が第一圧力状態に調整される。そして続く第二密閉工程によって、第一圧力状態で密閉された下空間内に、同じく第一圧力状態で密閉された囲い空間（Ｃ）が形成される。密閉状態の下空間内で保持枠（３２）を上下移動させ、気密性を保つまで接触させることで、第一圧力状態の囲い空間（Ｃ）が容易に形成されることとなる。また上下移動可能な保持枠（３２）を使用することで、被着体（Ｗ）を上方へ大幅に動かすことなく、容易かつ確実に囲い空間（Ｃ）を密閉形成することができる。 According to the first sealing step, the vertically movable holding frame (32) is arranged in advance near the upper portion of the upper opening or near the lower portion of the lower opening, and the decorative film held by the holding frame (32). (F) will be accommodated in the upper space (A) or the lower space that is vertically sealed. In this state, the enclosed space (C) is not formed in the lower space, and the entire lower space is adjusted to the first pressure state by the subsequent first pressure adjusting step. Then, in the subsequent second sealing step, the enclosure space (C) that is also sealed in the first pressure state is formed in the lower space that is sealed in the first pressure state. By vertically moving the holding frame (32) in the closed lower space and bringing them into contact with each other until the airtightness is maintained, the enclosed space (C) in the first pressure state can be easily formed. Further, by using the vertically movable holding frame (32), it is possible to easily and reliably form the enclosed space (C) hermetically without significantly moving the adherend (W) upward.

特に実施例１では、連結棒を回転させ、保持枠（３２）を囲い枠体（３３）に接触するまで下降させることで、被着体（Ｗ）上に配置された囲い枠体（３３）の上接触面と、保持枠（３２）下部の対向接触面と、を接触させる。加飾成形範囲（ＭＡ）の平面視外方の被着体（Ｗ）上には予め囲い枠体（３３）が接触配置されており、保持枠（３２）の枠内部には予め加飾フィルム（Ｆ）が張架してセットされている。このため、前記囲い枠体（３３）と保持枠（３２）との対向接触によって、被着体（Ｗ）の加飾成形範囲（ＭＡ）と囲い枠体（３３）の枠内面と加飾フィルム（Ｆ）とに囲われた囲い空間（Ｃ）が密閉形成される（図９（ａ）（ｂ））。

前記の第二密閉工程によれば、加飾成形範囲（ＭＡ）の加飾面のみを囲い枠で囲うことで、上部に加飾フィルム（Ｆ）が張設された密閉状態の囲い空間（Ｃ）を、第一圧力状態に制御された密閉状態の下区画空間内に形成することができる。前記の第二圧力調整工程によれば、密閉状態の囲い空間（Ｃ）内を第一圧力状態に維持した状態のまま、上空間（Ａ）内を瞬間的に加圧することで、上空間（Ａ）と囲い空間（Ｃ）の圧力差によって加飾成形範囲（ＭＡ）に瞬間的に加飾成形を行うことができる。また、前記の第二圧力調整工程によれば、上空間（Ａ）内と下区画空間内とを互いに等圧力のまま瞬間的に加圧することで、囲い空間（Ｃ）を除く下区画空間内には圧力差による影響が生じない。 According to the second sealing step, by surrounding only the decorative surface of the decorative molding range (MA) with the surrounding frame, the decorative film (F) is stretched over the enclosed space (C). ) Can be formed in the closed lower compartment space controlled to the first pressure state. According to the above-mentioned second pressure adjusting step, the upper space (A) is momentarily pressurized while the closed space (C) is maintained in the first pressure state, whereby the upper space ( The decorative molding can be instantaneously performed in the decorative molding area (MA) by the pressure difference between A) and the enclosed space (C). Further, according to the second pressure adjusting step, the upper space (A) and the lower compartment space are momentarily pressurized while maintaining the same pressure, so that the lower compartment space excluding the enclosed space (C). Is not affected by the pressure difference.

このように上空間（Ａ）と下区画空間の間の第三の密閉空間として、下区画空間内に囲い空間（Ｃ）を形成することにより、被着体（Ｗ）の加飾面の裏側に窪みや孔や隙間がある場合であっても、第二圧力工程による急激な圧力差による影響を受けることがない。
また、被着体（Ｗ）を受け冶具等で支える場合でも、被着体（Ｗ）の下面側を同じ圧力とするための導圧回路を設ける必要がなく、被着体（Ｗ）の減圧時の成形保持性能に拘らず、複雑な形状の被着体（Ｗ）であっても、比較的簡易な構造で確実に被着体（Ｗ）の部分加飾成形を行うことができる。例えば範囲の裏側に微細な穴ないし孔、溶接部、接着部、或いは内部空間が存在していた場合でも、被着面の部分加飾成形範囲（ＭＡ）において密閉状態の囲い空間（Ｃ）が形成されることで、被着体（Ｗ）の成形部分が変形したり欠損したりすることなく、また、圧力漏れが生じることもない。 Thus, by forming the enclosed space (C) in the lower compartment space as the third closed space between the upper compartment (A) and the lower compartment space, the back side of the decorative surface of the adherend (W) Even if there are pits, holes, or gaps, there is no effect due to a sudden pressure difference due to the second pressure step.

Even if the adherend (W) has a complicated shape, the partial decorative molding of the adherend (W) can be surely performed with a relatively simple structure regardless of the molding holding performance. For example, even if there are fine holes or holes, welded portions, bonded portions, or internal spaces on the back side of the range, the enclosed space (C) in the sealed state in the partial decorative molding range (MA) of the adherend is By being formed, the molded part of the adherend (W) is not deformed or chipped, and pressure leakage does not occur.

（囲いアングルの密閉形成）
実施例２では、規制アングル（４２）を下降させ、規制アングル（４２）の下部に接触させた保持枠（３２）をベース枠体（１６）の枠底面に近接するように下降させることで、被着体（Ｗ）の加飾成形範囲（ＭＡ）を含む接触面と、加飾フィルム（Ｆ）とを接触させる。前記保持枠（３２）の下降によって、被着体（Ｗ）の加飾成形範囲（ＭＡ）と加飾フィルム（Ｆ）とに囲われた囲い空間（Ｃ）が密閉形成される（図１３（ｅ））。 (Enclosure of enclosure angle)
In the second embodiment, the regulation angle (42) is lowered, and the holding frame (32) brought into contact with the lower portion of the regulation angle (42) is lowered so as to be close to the frame bottom surface of the base frame body (16). The contact surface of the adherend (W) including the decorative molding range (MA) is brought into contact with the decorative film (F). By lowering the holding frame (32), an enclosure space (C) surrounded by the decorative molding area (MA) of the adherend (W) and the decorative film (F) is hermetically formed (FIG. 13( e)).

このように上空間（Ａ）と下空間の間の第三の密閉空間として、下空間内に囲い空間（Ｃ）を形成することにより、被着体（Ｗ）の加飾面の裏側に窪みや孔や隙間がある場合であっても、第二圧力工程による急激な圧力差による影響を受けることがない。
また、被着体（Ｗ）を受け冶具等で支える場合でも、被着体（Ｗ）の下面側を同じ圧力とするための導圧回路を設ける必要がなく、被着体（Ｗ）の減圧時の成形保持性能に拘らず、複雑な形状の被着体（Ｗ）であっても、比較的簡易な構造で確実に被着体（Ｗ）の部分加飾成形を行うことができる。例えば範囲の裏側に微細な穴ないし孔、溶接部、接着部、或いは内部空間が存在していた場合でも、被着面の部分加飾成形範囲（ＭＡ）において密閉状態の囲い空間（Ｃ）が形成されることで、被着体（Ｗ）の成形部分が変形したり欠損したりすることなく、また、圧力漏れが生じることもない。 Thus, by forming the enclosed space (C) in the lower space as a third closed space between the upper space (A) and the lower space, a recess is formed on the back side of the decorative surface of the adherend (W). Even if there is a hole or a gap, it is not affected by the sudden pressure difference due to the second pressure step.
Further, even when the adherend (W) is supported by a jig or the like, it is not necessary to provide a pressure guiding circuit for keeping the lower surface side of the adherend (W) at the same pressure, and the pressure reduction of the adherend (W) is possible. Even if the adherend (W) has a complicated shape, the partial decorative molding of the adherend (W) can be surely performed with a relatively simple structure regardless of the molding holding performance. For example, even if there are fine holes or holes, welded portions, bonded portions, or internal spaces on the back side of the range, the enclosed space (C) in the sealed state in the partial decorative molding range (MA) of the adherend is By being formed, the molded part of the adherend (W) is not deformed or chipped, and pressure leakage does not occur.

前記の工程であれば、圧力制御装置として少なくとも、上ボックス（２）及び下ボックス（１）に連通する連通管とこれに接続する減圧ポンプを有していればよく、連通管をバイパスさせて減圧ポンプに連通させることで、簡易な機構をもって確実な圧力制御を行うことができる。 In the above step, at least a communication pipe communicating with the upper box (2) and the lower box (1) and a decompression pump connected to this may be provided as the pressure control device, and the communication pipe may be bypassed. By communicating with the decompression pump, reliable pressure control can be performed with a simple mechanism.

後述の実施例１では、連結棒を回転させ、保持枠（３２）を囲い枠体（３３）に接触するまで下降させることで、被着体（Ｗ）上に配置された囲い枠体（３３）の上接触面と、保持枠（３２）下部の対向接触面と、を接触させる。加飾成形範囲（ＭＡ）の平面視外方の被着体（Ｗ）上には予め囲い枠体（３３）が接触配置されており、保持枠（３２）の枠内部には予め加飾フィルム（Ｆ）が張架してセットされている。このため、前記囲い枠体（３３）と保持枠（３２）との対向接触によって、被着体（Ｗ）の加飾成形範囲（ＭＡ）と囲い枠体（３３）の枠内面と加飾フィルム（Ｆ）とに囲われた囲い空間（Ｃ）が密閉形成される（図９（ａ）（ｂ））。 In Example 1 described later, the connecting rod is rotated and the holding frame (32) is lowered until it comes into contact with the surrounding frame body (33), so that the surrounding frame body (33) arranged on the adherend (W). 2) and the opposing contact surface under the holding frame (32) are brought into contact with each other. The surrounding frame body (33) is arranged in contact with the adherend (W) outside the decorative molding range (MA) in plan view, and the decorative film is previously arranged inside the holding frame (32). (F) is stretched and set. Therefore, the decorative molding range (MA) of the adherend (W), the inner surface of the frame (33) and the decorative film are provided by the facing contact between the surrounding frame (33) and the holding frame (32). An enclosure space (C) surrounded by (F) and (F) is hermetically formed (FIGS. 9A and 9B).

実施例１のように囲い枠体（３３）を用いた第二密閉工程であれば、下降した保持枠（３２）との接触状態、或いは被着体（Ｗ）上の配置接触の状態に因らず、囲い空間（Ｃ）をより確実に気密形成することができる。実施例１では、囲い枠体（３３）全体が、外接触部との気密性を保持する弾性材からなる。他の形態として、囲い枠体（３３）の外周部全体が、外接触部との気密性を保持する弾性材によって覆設されてなるものでもよい。 In the case of the second sealing step using the enclosing frame body (33) as in the first embodiment, the state of contact with the lowered holding frame (32) or the state of arrangement contact on the adherend (W) is caused. Therefore, the enclosed space (C) can be formed more reliably in an airtight manner. In the first embodiment, the entire enclosing frame body (33) is made of an elastic material that maintains airtightness with the outer contact portion. As another form, the entire outer peripheral portion of the surrounding frame (33) may be covered with an elastic material that maintains airtightness with the outer contact portion.

実施例１では、連結棒を回転させ、保持枠（３２）を締付ベース体（３）に近接するように下降させることで、被着体（Ｗ）上に配置された囲い枠体（３３）の接触面と、前記保持枠（３２）の対向接触面と、を近接させて加圧接触させると共に、被着体（Ｗ）上に配置された囲い枠体（３３）の接触面と、被着体（Ｗ）の対向接触面と、を近接させて加圧接触させる。 In the first embodiment, by rotating the connecting rod and lowering the holding frame (32) so as to be close to the tightening base body (3 ), the surrounding frame body (33) arranged on the adherend (W). ) And the opposing contact surface of the holding frame (32) in close proximity to each other for pressure contact, and a contact surface of the surrounding frame body (33) arranged on the adherend (W), The opposing contact surface of the adherend (W) is brought close to and brought into pressure contact.

また実施例２では、規制アングル（４２）を下降させ、規制アングル（４２）の下部に接触させた保持枠（３２）をベース枠体（１６）の枠底面に近接するように下降させることで、被着体（Ｗ）の加飾成形範囲（ＭＡ）を含む接触面と、加飾フィルム（Ｆ）とを接触させる。前記保持枠（３２）の下降によって、被着体（Ｗ）の加飾成形範囲（ＭＡ）と加飾フィルム（Ｆ）とに囲われた囲い空間（Ｃ）が密閉形成される（図１３（ｅ））。 Further, in the second embodiment, the regulation angle (42) is lowered, and the holding frame (32) brought into contact with the lower portion of the regulation angle (42) is lowered so as to be close to the frame bottom surface of the base frame body (16). The contact surface including the decorative molding range (MA) of the adherend (W) is brought into contact with the decorative film (F). By lowering the holding frame (32), an enclosure space (C) surrounded by the decorative molding area (MA) of the adherend (W) and the decorative film (F) is hermetically formed (FIG. 13( e)).

実施例２のように被着体を受け冶具等で支える場合でも、被着体の下面側を同じ圧力とするための導圧回路を設ける必要がなく、被着体の減圧時の成形保持性能に拘らず、複雑な形状の被着体であっても、比較的簡易な構造で確実に被着体の部分加飾成形を行うことができる。例えば範囲の裏側に微細な穴ないし孔、溶接部、接着部、或いは内部空間が存在していた場合でも、被着面の部分加飾成形範囲において密閉状態の囲い空間が形成されることで、被着体の成形部分が変形したり欠損したりすることなく、また、圧力漏れが生じることもない。 Even when the adherend is supported by a jig or the like as in the second embodiment, it is not necessary to provide a pressure guiding circuit for keeping the lower surface side of the adherend at the same pressure, and the molding holding performance when the adherend is depressurized Regardless of the above, even if the adherend has a complicated shape, the partial decorative molding of the adherend can be reliably performed with a relatively simple structure. For example, even if there is a minute hole or hole on the back side of the range, a welded portion, an adhesive portion, or an internal space, by forming a closed enclosure space in the partial decorative molding range of the adherend, The molded part of the adherend is not deformed or damaged, and pressure leakage does not occur.

本発明では、被着体の上部に囲い枠体を接触させて加飾成形範囲を囲い、被着体を収容して密閉状態の上空間と密閉状態の下空間とを形成し、密閉状態の下空間及び上空間を、互いに等圧の所定の第一圧力状態としたのちに、加飾フィルムと加飾成形範囲の被着体とに上下を囲われた密閉状態の囲い空間を形成する。そして囲い空間内を第一圧力状態に維持したまま、囲い空間周囲の下空間と上空間とを、前記減圧状態から瞬間的に加圧し、互いに等圧の第二圧力状態とすることによって、囲い空間の加飾成形範囲に加飾フィルムを部分加飾成形する。但し下空間と上空間とは互いに等圧のまま瞬間的に加圧する。このように上空間と下区画空間の間の第三の密閉空間として、下区画空間内に囲い空間を形成することにより、被着体の加飾面の裏側に窪みや孔や隙間がある場合であっても、第二圧力工程による急激な圧力差による影響を受けることがない。 In the present invention, the enclosure frame is brought into contact with the upper part of the adherend to surround the decorative molding range, and the adherend is housed to form an upper space in a sealed state and a lower space in a sealed state. After the lower space and the upper space are brought into a predetermined first pressure state of equal pressure to each other, a sealed enclosure space that is vertically enclosed by the decorative film and the adherend in the decorative molding range is formed. Then, while maintaining the first pressure state in the enclosure space, the lower space and the upper space around the enclosure space are momentarily pressurized from the depressurized state to be in a second pressure state of equal pressure to each other. The decorative film is partially decorative-molded in the space decorative-molding range. However, the lower space and the upper space are momentarily pressurized while maintaining the same pressure. In this way, when there is a dent, a hole, or a gap on the back side of the decorative surface of the adherend by forming an enclosed space in the lower compartment space as a third closed space between the upper space and the lower compartment space. However, it is not affected by the sudden pressure difference due to the second pressure step.

前記の第二密閉工程によれば、加飾成形範囲の加飾面のみを囲い枠で囲うことで、上部に加飾フィルムが張設された密閉状態の囲い空間を、第一圧力状態に制御された密閉状態の下区画空間内に形成することができる。前記の第二圧力調整工程によれば、密閉状態の囲い空間内を第一圧力状態に維持した状態のまま、上空間内を瞬間的に加圧することで、上空間と囲い空間の圧力差によって加飾成形範囲に瞬間的に加飾成形を行うことができる。また、前記の第二圧力調整工程によれば、上空間内と下区画空間内とを互いに等圧力のまま瞬間的に加圧することで、囲い空間を除く下区画空間内には圧力差による影響が生じない。 According to the second sealing step, by enclosing only the decorative surface in the decorative molding range with the enclosing frame, the enclosed space in which the decorative film is stretched on the upper part controls the first pressure state. It can be formed in the enclosed lower compartment space. According to the second pressure adjustment step described above, by momentarily pressurizing the upper space while maintaining the enclosed space in the first pressure state, the pressure difference between the upper space and the enclosed space is increased. Decorative molding can be instantaneously performed in the decorative molding range. Further, according to the second pressure adjusting step described above, by instantaneously pressurizing the upper space and the lower compartment space with each other at the same pressure, the influence of the pressure difference in the lower compartment space excluding the enclosed space is affected. Does not occur.
