Description

The present invention provides a decorative molding method using a decorative sheet, in which a decorative sheet having an adhesive layer on the lower surface is applied to an adherend in a vacuum state and decoratively molded, and a decorative molding method used in this decorative molding method. In particular, the present invention relates to a decorative molding device for a relatively large adherend having a hollow structure, and a partial decorative molding method for decoratively molding a partial surface of the adherend, and this partial decorative molding. The present invention relates to a partial decoration molding device used in the method.

As a partial overlay method for partially decorating a large adherend such as a car body with a film, a storage chamber with an upper opening and an upper box with an opening at the lower part are placed one above the other with a decorative film sandwiched between them. In combination with this, a molding space in which the box space and the storage space are connected vertically is formed in a sealed manner, and by creating an instantaneous pressure difference between the upper and lower spaces in this molding space, the objects stored in the molding space are A device is disclosed in which a decorative film is brought into close contact with a part of the surface of the wearer W under reduced pressure (Patent Document 1).

On the other hand, for large-sized adherends made of molded plate materials, the back side of the molded surface is often reinforced with a lower panel, and a hollow structure is formed by the upper panel and the lower panel. For example, a front suspension member for an automobile is disclosed that is formed into a hollow structure by an upper panel and a lower panel, and has a front arm attachment portion and a rear arm attachment portion on each side in the lateral direction (Patent Document 2). ). For example, the hollow structure has a vertical wall extending substantially linearly from the front arm attachment part to the rear arm attachment part, and the rear arm attachment part extends the upper panel in the lateral direction. and a brace welded to the lower panel and extending laterally.

However, if the molded plate material includes a part of the hollow structure within the partially decorative molding range, when the molded plate material is decorated with a decorative film, the pressure on the back side of the molded plate material is instantaneously and rapidly reduced, and the hollow structure is crushed and deformed. In other words, in decorative molding using a decorative film, the storage space that accommodates the molded plate material in the decorative molding range and the upper box space above the storage space bordered by the decorative film are kept in an equal pressure state. The state is rapidly changed from an equal pressure state to a reduced pressure state where the pressure inside the accommodation space is significantly reduced relative to the box space. During this rapid state change, the accommodation space becomes instantaneously depressurized, so if an adherend with a hollow structure is accommodated in the accommodation space, this hollow structure may be crushed due to the depressurization state change. , it is affected by deformation due to depressurization.

In order to avoid the influence of this reduced pressure, it is also possible to bypass ventilation of the hollow structure part of the housing space with the upper box space, so that only the interior of the hollow structure can partially maintain an equal pressure state with the upper box space. In order to maintain a partially equal pressure state inside the hollow structure through such a ventilation bypass, it is necessary to maintain the hollow structure in an airtight state and control the pressure of only the hollow structure part to be equal to the upper box space. .

However, since the hollow structure is formed by spot welding or block welding the lower panel from the back side of the upper panel of the adherend made of molded plate material, a part of the lower panel constituting the hollow structure often has holes or holes. or a gap between the upper panel and the upper panel. For this reason, it has been structurally extremely difficult to maintain the airtightness of the hollow structure.

Therefore, in the present invention, even when a part of the hollow structure is included in the partial decoration molding range, partial decoration molding can be performed reliably while avoiding crushing deformation due to changes in the reduced pressure state of the hollow structure. An object of the present invention is to provide a decorative molding method and a partial decorative molding device.

The following measures have been taken to resolve the above issues.
(1) A predetermined area of the surface near one end of the adherend is set as a decoration molding area, and a predetermined partial decoration molding device is used to
A predetermined area of the surface near one end of the adherend is set as a decorative molding area, and using a predetermined partial decoration molding device,
A partial decorative molding method using a decorative film, which partially decoratively molds an adherend by bringing a decorative film into close contact with this decorative molding range,
A decorative film is housed in a stretched state inside a box-shaped or container-shaped enclosing frame that opens downward, and the enclosing frame is brought into contact with the upper part of the adherend to enclose the decorative molding area. A sealed upper space (A) and a sealed lower space partitioned by a decorative film are defined between the decorative film and the decorative molding range. After the lower space (B) and the upper space (A) in the sealed state are brought into a predetermined reduced pressure state where the pressure is equal to each other, the upper space (A) is opened while the inside of the lower space (B) is maintained at the first pressure state. 1. A method for partially decorating and molding, characterized in that a decorative film is partially decoratively molded in a decorative molding range of an enclosed space by instantaneously releasing atmospheric pressure from the reduced pressure state.
(2) The predetermined partial decoration molding device includes:
an enclosing frame body having a box-like space opened at the bottom and placed in contact with the upper part of the adherend, surrounding the outer edge of the decorative molding range that is one end of the adherend;
In this box-shaped space, the decorative film is stretched by holding the periphery of the decorative film spread laterally inside the enclosing frame body that accommodates the adherend with the decorative molding area facing upward. a holding frame that can be hung;
A pressure control device that controls the pressure of the sealed space within the enclosure frame in contact with the adherend to a reduced pressure state or an atmospheric pressure released state,
Using the predetermined partial decoration molding device,
A decorative film larger than the planar projected area of the decorative molding range is spread out laterally at a predetermined height position within the bottom-opened enclosure frame, and the periphery of the decorative film is held by a holding frame. In the film setting process, the lower opening of the enclosing frame faces the decorative molding area of the adherend, and the decorative film is placed in the space inside the enclosing frame by closely contacting it via the elastic material attached to the lower opening of the enclosing frame. a sealing process in which an upper space and a lower space in a sealed state are connected vertically on an adherend with the space between them;
a first pressure adjustment step in which the pressure control device brings the lower space in the sealed state and the upper space in the sealed state into a predetermined first pressure state where the pressure is equal to each other;
While maintaining the inside of the sealed lower space at the first pressure state, the pressure control device momentarily releases the sealed upper space from the depressurized state to atmospheric pressure, and the pressure difference between the upper and lower spaces causes the pressure to be increased. The present invention is characterized by sequentially comprising a decoration molding step of instantaneously and uniformly adhering the decorative film to the adherend.
In addition, after the decorative molding process, an adjustment frame is set around the decorative molding range of the adherend, and from above these, the excess decorative film end protruding outside the decorative molding range is cut in a predetermined manner. It further includes a cutting process of laser cutting on the orbit.
Further, after the sealing step and before the decorative molding step,
The decorative film stretched in the closed space inside the enclosure frame is heated from above and from the sides by multiple heaters provided on the inner surface and the inner top surface of the enclosure frame to soften, stretch, and relax, and then adhere. The device further includes a drawdown step of bringing the device into a drawdown state close to the body.

According to the second sealing step, by enclosing only the decorative surface of the decorative molding range with an enclosing frame, the enclosed space in the sealed state, on which the decorative film is stretched, is controlled to the first pressure state. It can be formed in the lower space of a sealed state. According to the second pressure adjustment step, the inside of the upper space is momentarily pressurized while the inside of the closed enclosed space is maintained at the first pressure state, so that the pressure difference between the upper space and the enclosed space is increased. Decorative molding can be instantaneously performed in the decorative molding range. In addition, according to the second pressure adjustment step, by instantly pressurizing the upper space and the lower space while keeping the pressure equal to each other, the lower space except the enclosed space is collapsed due to rapid depressurization. etc. will not occur.

By forming an enclosed space within the lower space as the third sealed space between the upper space and the lower space, it is possible to eliminate the problem when there are depressions, holes, or gaps on the back side of the decorated surface of the adherend. However, it is not affected by the sudden pressure difference caused by the second pressure step.
In addition, even when supporting the adherend with a jig or the like, there is no need to provide a pressure conduction circuit to maintain the same pressure on the lower surface of the adherend, regardless of the mold retention performance when the adherend is depressurized. Even if the adherend has a complicated shape, it is possible to reliably perform partial decorative molding of the adherend with a relatively simple structure. For example, even if there are minute holes, welded parts, adhesive parts, or internal spaces on the back side of the area, a sealed enclosed space is formed in the partially decorated molded area of the adhered surface. The molded part of the adherend will not be deformed or damaged, and no pressure leaks will occur.

(3) The first pressure step is a step of simultaneously suctioning the inside of the sealed lower space excluding the enclosed space and the sealed upper space to create a first pressure state where the pressure is lower than atmospheric pressure,
In the second pressure adjustment step, the inside of the lower space in the sealed state and the upper space in the sealed state, excluding the enclosed space, which were brought into the first pressure state in the first pressure adjustment step, are simultaneously opened to atmospheric pressure to bring the pressure to the atmospheric pressure. It is preferable that the step is a step of creating a second pressure state equal to the pressure.

In the above process, the pressure control device only needs to have at least a communication pipe communicating with the upper box and the lower box and a pressure reducing pump connected to the communication pipe, and it is possible to perform reliable pressure control with a simple mechanism. can.

(4) In the first sealing step, the edges of the decorative film spread in the horizontal direction are held and fixed by a vertically movable holding frame;
By connecting the upper space and the lower space, a holding frame holding the decorative film is housed in the lower space or the upper space,
In the second sealing step, the holding frame is lowered to bring the holding frame into opposing contact with the contact upper surface of the adherend including the decorative molding area or with the contact surface of the surrounding frame disposed on the adherend. By bringing the surfaces into contact with each other, an enclosed space is formed that is surrounded by the contact upper surface of the decorative molding range of the adherend, the inner surface of the surrounding frame, and the lower surface of the decorative film. preferable.

According to the first sealing step, a vertically movable holding frame is placed in advance near the top of the top opening or near the bottom of the bottom opening, and the decorative film held by the holding frame is vertically sealed in a series. It will be housed inside the upper space or lower space created. In this state, no enclosed space is formed in the lower space, and the entire lower space is adjusted to the first pressure state in the subsequent first pressure adjustment step. In the subsequent second sealing step, an enclosed space also sealed under the first pressure condition is formed within the lower space sealed under the first pressure condition. By moving the holding frame up and down in the sealed lower space and bringing them into contact until airtightness is maintained, an enclosed space in the first pressure state can be easily formed. Furthermore, by using a vertically movable holding frame, it is possible to easily and reliably seal the enclosed space without significantly moving the adherend upward.

In Example 1, which will be described later, by rotating the connecting rod and lowering the holding frame until it comes into contact with the surrounding frame, the upper contact surface of the surrounding frame placed on the adherend and the lower part of the holding frame face each other. Bring the contact surface into contact with the contact surface. An enclosing frame body is placed in advance in contact with the adherend on the outside of the decorative molding range in plan view, and a decorative film is set in advance in a stretched manner inside the frame of the holding frame. Therefore, due to the opposing contact between the enclosing frame and the holding frame, an enclosed space surrounded by the decorative molding range of the adherend, the inner surface of the enclosing frame, and the decorative film is formed in a hermetically sealed manner (Fig. 9 (a)(b)).

In addition, in Example 2, which will be described later, by lowering the regulating angle and lowering the holding frame that is in contact with the lower part of the regulating angle so as to approach the bottom surface of the frame of the base frame body, the decorative molding range of the adherend is reduced. The contact surface containing the decorative film is brought into contact with the decorative film. By lowering the holding frame, an enclosed space surrounded by the decorative molding range of the adherend and the decorative film is formed in a sealed manner (FIG. 13(e)).

(5) The enclosing frame body has an elastic material that can be elastically deformed by pressurized contact in at least one of the contact portion disposed on the adherend and the contact portion with the opposing contact surface of the holding frame. Become,
The second sealing step is performed by bringing the contact surface of the adherend including the decorative molding area or the contact surface of the surrounding frame disposed on the adherend close to the opposing contact surface of the holding frame. It is preferable that the pressure contact forms an enclosed space surrounded by the upper surface of the decorative molding area of the adherend, the inner surface of the surrounding frame body, and the lower surface of the decorative film in an airtight manner.

In the second sealing step using the enclosing frame, the enclosed space can be more reliably airtight regardless of the contact state with the lowered holding frame or the arrangement contact state on the adherend. can. In the embodiments described below, the entire enclosure frame is made of an elastic material that maintains airtightness with the external contact portion. As another form, the entire outer periphery of the enclosure frame may be covered with an elastic material that maintains airtightness with the external contact portion.

For example, in Example 1, which will be described later, by rotating the connecting rod and lowering the holding frame close to the tightening base, the contact surface of the enclosing frame placed on the adherend and the holding frame are brought into close contact with each other under pressure, and the contact surface of the enclosure disposed on the adherend and the opposite contact surface of the adherend are brought into close contact with each other under pressure.

(6) The adherend has an opening at the bottom of the surface having the decorative molding range,
The predetermined partial decoration molding device further includes:
a tightening base body that is disposed to be engaged with the opening of the adherend, and a portion of which can protrude outward from the outer edge of the decorative molding range in a plan view of the adherend;
A connecting rod capable of vertically connecting the tightening base body and the holding frame and shortening the vertical connection distance,
In the housing step, the adherend is housed in the lower box with the tightening base body locked and disposed in the opening of the adherend,
In the film setting step, the holding frame is placed above the tightening base body and above the enclosing frame body, and the holding frame and the tightening base body are vertically connected by a connecting rod,
In the second sealing step, the distance between the vertically connected holding frame and the clamping base body is shortened, the distance between the clamping base body and the holding frame is brought closer, and the clamping base body and the holding frame are enclosed by the clamping base body and the holding frame. It is preferable to press the frame vertically to form an enclosed space surrounded by the upper surface of the decorative molding range of the adherend, the inner surface of the enclosure frame, and the decorative film in a hermetically sealed manner.

With the above configuration, the enclosed space connected vertically via the decorative film can be easily and reliably sealed by the elastic tightness of the holding frame which is open at the bottom.

The holding frame is composed of a portable main body frame 22 equipped with a holding frame 32, and the pressure regulating device is composed of a portable vacuum pump VP equipped with communication pipes 1P/2P and a switch valve SV. Good too. Further, the laser cutting device is not necessarily essential, and if necessary, a portable cutting device including only the laser irradiator 32 with a handle that can be held in the hand may be used.

With the above configuration, the present invention forms an enclosed space surrounded by the decorative film and the decorative molding range of the adherend as the third sealed space between the upper space and the lower space, and forms the enclosed space and the enclosed space. Decorative molding is performed by creating a pressure difference between the surrounding upper and lower spaces. As a result, even if there are depressions, holes, or gaps on the back side of the decorated surface of the adherend, it is not affected by the sudden pressure difference caused by the second pressure step. In addition, even when supporting an adherend with a receiving jig, etc., there is no need to provide a conductive circuit in the receiving jig, etc. to maintain the same pressure on the bottom side of the adherend, and it is possible to support the adherend with a complicated shape. Also, it has become possible to reliably perform partial decorative molding of an adherend with a relatively simple structure. As a result, even if there are minute holes, welded parts, adhesive parts, or internal spaces on the back side of the area, a sealed enclosed space is formed in the area of the partially decorated molding area of the adherend surface. This makes it possible to reliably perform decorative molding using a pressure difference without deforming or chipping the molded portion of the adherend, and without causing pressure leaks.

Regardless of the mold retention performance at the time, even if the adherend (W) has a complicated shape, partial decorative molding of the adherend (W) can be reliably performed with a relatively simple structure. For example, even if there is a minute hole, a welded part, an adhesive part, or an internal space on the back side of the area, the enclosed space (C) in a sealed state will not exist in the partially decorated molding area (MA) of the adherend surface. Due to this formation, the molded portion of the adherend (W) will not be deformed or damaged, and no pressure leakage will occur.

According to the second pressure adjustment step, the upper space (A) is instantly pressurized while the closed enclosed space (C) is maintained at the first pressure state. Decorative molding can be instantaneously performed in the decorative molding area (MA) due to the pressure difference between A) and the enclosed space (C). In addition, according to the second pressure adjustment step, by instantly pressurizing the inside of the upper space (A) and the inside of the lower space while keeping the pressure equal to each other, the lower space (B) excluding the enclosed space (C) is There is no effect due to pressure difference inside.

By forming the enclosed space (C) in the lower space as the third sealed space between the upper space (A) and the lower space in this way, a depression is formed on the back side of the decorated surface of the adherend (W). Even if there are holes or gaps, the device will not be affected by the sudden pressure difference caused by the second pressure step.
In addition, even when supporting the adherend (W) with a jig, etc., there is no need to provide a conductive circuit to maintain the same pressure on the lower surface of the adherend (W), and the pressure of the adherend (W) is reduced. Regardless of the mold retention performance at the time, even if the adherend (W) has a complicated shape, partial decorative molding of the adherend (W) can be reliably performed with a relatively simple structure. For example, even if there is a minute hole, a welded part, an adhesive part, or an internal space on the back side of the area, the enclosed space (C) in a sealed state will not exist in the partially decorated molding area (MA) of the adherend surface. Due to this formation, the molded portion of the adherend (W) will not be deformed or damaged, and no pressure leakage will occur.

In the above process, the pressure control device only needs to have at least a communication pipe communicating with the upper box (2) and the lower box (1) and a pressure reducing pump connected thereto, and the communication pipe may be bypassed. By communicating with the decompression pump, reliable pressure control can be performed with a simple mechanism.

In this state, no enclosed space (C) is formed in the lower space, and the entire lower space is adjusted to the first pressure state in the subsequent first pressure adjustment step. In the subsequent second sealing step, an enclosed space (C) also sealed under the first pressure condition is formed within the lower space sealed under the first pressure condition. By moving the holding frame (32) up and down in the sealed lower space and bringing them into contact until airtightness is maintained, the enclosed space (C) in the first pressure state can be easily formed. Furthermore, by using the vertically movable holding frame (32), the enclosed space (C) can be easily and reliably sealed without moving the adherend (W) upward significantly.

In Example 1, which will be described later, by rotating the connecting rod and lowering the holding frame (32) until it comes into contact with the surrounding frame (2), the surrounding frame (2) placed on the adherend (W) is removed. ) and the opposing contact surface of the lower part of the holding frame (32) are brought into contact.

Therefore, due to the opposing contact between the enclosing frame body (2) and the holding frame (32), the decorative molding area (MA) of the adherend (W), the frame inner surface of the enclosing frame body (2), and the decorative film (F) and an enclosed space (C) is formed in a sealed manner (FIGS. 9(a) and 9(b)).

In the second sealing step using the enclosure frame (2) as in Example 1, the contact condition with the lowered holding frame (32) or the placement contact condition on the adherend (W) may cause Therefore, the enclosed space (C) can be formed airtight more reliably. In Example 1, the entire enclosure frame (2) is made of an elastic material that maintains airtightness with the external contact portion. As another form, the entire outer periphery of the enclosure frame (2) may be covered with an elastic material that maintains airtightness with the external contact portion.

By lowering the holding frame (32), an enclosed space (C) surrounded by the decorative molding area (MA) of the adherend (W) and the decorative film (F) is formed in a hermetically sealed manner (see FIG. 13). e)).

Even when the adherend is supported with a receiving jig, etc. as in Example 2, there is no need to provide a pressure circuit to maintain the same pressure on the lower surface of the adherend, and the mold retention performance when the adherend is depressurized is improved. Regardless, even if the adherend has a complicated shape, it is possible to reliably perform partial decorative molding of the adherend with a relatively simple structure. For example, even if there are minute holes, welded parts, adhesive parts, or internal spaces on the back side of the area, a sealed enclosed space is formed in the partially decorated molded area of the adhered surface. The molded part of the adherend will not be deformed or damaged, and no pressure leaks will occur.

In the present invention, an enclosing frame body is brought into contact with the upper part of the adherend to enclose the decorative molding area, and the adherend is accommodated 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 to a predetermined first pressure state where the pressure is equal to each other, a sealed enclosed space is formed in which the upper and lower sides are surrounded by the decorative film and the adherend in the decorative molding range. Then, while maintaining the inside of the enclosed space at the first pressure state, the lower space and upper space around the enclosed space are momentarily pressurized from the reduced pressure state to bring them to a second pressure state where the pressure is equal to each other. A decorative film is partially decoratively molded in the decorative molding range of the space. However, the lower space and the upper space are momentarily pressurized while maintaining the same pressure.

It can be formed in a sealed lower compartment space. According to the second pressure adjustment step, the inside of the upper space is momentarily pressurized while the inside of the closed enclosed space is maintained at the first pressure state, so that the pressure difference between the upper space and the enclosed space is increased. Decorative molding can be instantaneously performed in the decorative molding range. In addition, according to the second pressure adjustment step, by instantly pressurizing the upper space and the lower compartment space with the same pressure, the lower compartment space except the enclosed space is affected by the pressure difference. does not occur.
