[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transfer device for transferring a material to be transferred, for example, a three-dimensional molded product by using a transfer material.

[0002]

2. Description of the Related Art Conventionally, transfer devices have been widely used to form pictures, characters, and the like on the surface of various articles such as home appliances, cosmetic containers, and decorative articles.

The transfer material used in the above transfer apparatus is basically of a layer structure in which a transfer layer such as a picture layer and an adhesive layer is provided on a release sheet, and a surface protective layer may be provided if necessary. When the picture layer has adhesiveness, the adhesive layer is omitted.

As the transfer method in the transfer material apparatus, roll transfer, up-down transfer and the like are well known.
Widely used for home appliances, cosmetics, miscellaneous goods, etc. In such a transfer method, the transfer material is placed on the transfer object, and the heated silicon rubber is pressed from above the transfer material toward the transfer object by a roller or a pressing member that moves up and down, and the like. The transfer pattern of the transfer material is configured to be transferred onto the transfer target. In the case of roll transfer, the above-mentioned silicon rubber having a thickness of usually 10 to 50 mm and a hardness of 60 to 90 degrees is used, and in the case of up-down transfer, usually a thickness of 2 to 5 mm and a hardness of 60 to 90 degrees. Is used.

[0005]

However, in these transfer devices, since the contact pressure portion of the silicon rubber, which is a heat source, is linear or planar, the transfer target has a two-dimensional structure.

In the above configuration, the mounting table has a plurality of suction holes, and includes a suction member that performs suction from the suction holes when the transfer material comes into contact with the transfer target and transfer is performed. It can also be configured as follows.

According to the present invention, a transfer table on which a transfer object is placed and having a plurality of suction holes is opposed to a transfer area of the transfer object placed on the transfer table via a transfer material. A flexible sheet, a sheet supporting member supporting the sheet, a heating member supported by the supporting member and heating the sheet, and supplying a fluid to the supporting member to expand the sheet and to pressurize the sheet. A fluid supply / discharge device, a driving member for relatively moving the support member supporting the sheet with respect to the transfer object on the mounting table, and the transfer material contacting the transfer object. When the transfer takes place,
A suction member that performs suction of the fluid between the transfer object and the transfer material by suction from the suction hole of the mounting table, and the transfer object is thin and has a concave portion on the lower surface, A second auxiliary table is provided on the mounting table or the first auxiliary table, the second auxiliary table being provided in the mounting table or the first auxiliary table and capable of communicating with the suction hole of the mounting table.

[0020]

According to the structure of the transfer device of the present invention, when the heated sheet is brought into contact with the transfer material and the transfer material is moved along the transfer object, an auxiliary member is used. For example, a transfer material supporting member or a first auxiliary member or a second auxiliary member is provided so that the transfer material can be more closely adhered to the transferred object by these members, so that the transferred material can be reliably transferred to the transferred object. Is done. That is, when the transfer material support member is provided on a mounting table, the support portion itself of the transfer material support member or a predetermined portion of the transfer material between the support portion and the sheet, for example, a corner of the transfer target body. In order to support the part that is opposed to the part and wrinkles easily,
The portion of the transfer material facing the transfer object corner is positioned at a predetermined position before the transfer material is stretched, and in this state, the transfer material is stretched along the transfer object corner using the extension of the transfer material. This makes it possible to more reliably align the transfer material along the object to be transferred while effectively preventing wrinkles. Further, in the apparatus provided with the first auxiliary member having a side surface depressed from the side surface of the transfer object, the side surface of the first auxiliary member is located closer to the center of the transfer object than the side surface of the transfer object. The material can surely adhere to the end of the transfer object on the mounting table side, and transfer can be performed more reliably. further,
When the transfer-receiving body is thin and has a concave portion on the lower surface, the suction member provided with the second auxiliary member having a suction hole which fits into the concave portion and communicates with the suction hole of the mounting table is provided. When the fluid between the transfer object and the transfer material is sucked, the fluid between the transfer object and the transfer material can also be sucked through the suction hole of the mounting table and the suction hole of the second auxiliary member. Therefore, the transfer material can be brought into close contact with the surface of the transfer object by the sheet while supporting the thin transfer object by the second auxiliary member, and the excess fluid between the transfer object and the transfer material can be surely removed. Thus, the transfer of the transfer material to the transfer object can be performed more reliably.

Therefore, according to the present invention, even if the surface of the object to be transferred has a three-dimensional shape or the object to be transferred has a portion which is easily wrinkled, the sheet and the transfer material can be three-dimensionally transferred to the object to be transferred. The design layer can be made to conform to the shape, particularly the above-mentioned portion, and the pattern layer of the transfer material can be easily and reliably transferred to the transfer target having a three-dimensional shape. Therefore, for example, not only the above-mentioned portion of the object to be transferred is sharp but also to the object to be transferred in which the radius is formed, the sheet and the transfer material contact along the radius portion, so that the transfer is also performed to the radius portion. The pattern layer of the material is clearly and reliably transferred. Further, even if the transfer object has a concave portion or the like, the transfer material can be brought into close contact with the wall surface in the concave portion by sucking the gas in the concave portion with the suction member, so that clear transfer can be performed to the concave portion.

As a method of transferring a three-dimensional shape of a transfer object with a transfer material, there is an in-mold transfer method.
In the in-mold transfer method, since the transfer material is previously inserted into the molding die, there is a disadvantage that the arrangement of the transfer material is restricted or the molding die becomes complicated. There are no major drawbacks.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments according to the present invention will be described below with reference to FIGS.
This will be described in detail based on 11, 12, and 14.

As shown in FIG. 1, the transfer apparatus according to the present embodiment places a transfer target 1 on a mounting table 2 and transfers a heated flexible sheet 4 supported by a support member 5. The support member 5 is lowered with respect to the mounting table 2 by driving a driving member (not shown) with the transfer object 3 interposed therebetween with the transfer material 3 interposed therebetween, and the sheet 4 is interposed between the transfer material 3 The transfer is performed by pressing the transfer member 1 against the transfer target 1 in a pressurized state.

As shown in a plan view of FIG. 6, the mounting table 2 has a wall 2b surrounding the object 1 mounted on the upper surface thereof and higher than the object 1, and A large number of suction holes 2a,
, 2a are formed, and these suction holes 2a,..., 2a are connected to the suction member 12, and mainly suction the gas between the transfer object 1 and the transfer material 3. Further, after the transfer target 1 on the mounting table 2 is placed, wrinkles are formed when a predetermined portion of the transfer target 1, that is, the transfer material 3 which is a flat surface is made to follow the transfer target 1 which is three-dimensional. Four transfer material supporting members 2d each having an L-shaped flat surface are provided at an easy part, specifically, for example, at a position facing a corner part. The height of each transfer material supporting member 2d is the same as or higher than that of the object 1 to be transferred, and the upper surface thereof is configured as a flat surface as a support portion. Part can be pinched. The support formed as a flat surface on the upper surface of the transfer material support member 2d is not limited to a flat surface and may be a curved surface, and any other surface can be used as long as the transfer material 3 can be sandwiched between the sheet 4 and the surface. Things are fine. Also,
The transfer material supporting member 2d may be formed integrally with the mounting table 1 instead of being formed separately.

The transfer material 3 is placed on a release sheet 3b made of a base film having releasability.
When peeled off, a release layer remaining on the design layer side and functioning as a protective layer of the design layer 3a, a design layer 3a having a pattern such as a pattern, and an adhesive layer are sequentially laminated to form a roll. Things. The pattern layer 3a may be a multilayer and may include a metal deposition layer. Also, the design layer 3a
May include a surface protective layer as necessary. That is, the "design layer" includes a surface protection layer such as colorless and transparent for protecting the surface of the transfer-receiving body, and a base adjustment layer as a base in a case where a picture is drawn with a brush regardless of transfer.

On both sides of the area where the mounting table 2 and the support member 5 face each other, a feed roller 8 and a take-up roller 9 are provided, respectively.
And are arranged. The roll-shaped transfer material 3 is sequentially sent out from the sending-out roller 8 toward the take-up roller 9, and when the desired symbol layer 3 a is transferred to the transfer-receiving body 1, a predetermined pitch is formed from the sending-out roller 8 to the release sheet 3 b. While the new design layer 3a is fed out, the release sheet 3b from which the design layer 3a has been transferred and removed is
It is wound up. The transfer material 3 is not limited to a roll-shaped material, but may be formed of a short fence-shaped sheet, and may be replaced each time transfer is performed once.

The sheet 4 may be any material that can be elastically deformed along the three-dimensional shape of the transfer object 1 and has heat resistance, such as silicon rubber having a thickness of about 1 to 3 mm.

The support member 5 has a plate-like heating member 6 disposed on a surface of the main body 5a facing the transfer-receiving body 1 and a sheet 4 on a peripheral portion of the main body 5a surrounding the heating member 6.
And support it. The heating member 6 has a rough surface and a rough surface, and a large number of fine holes 6a,
, 6a are formed as fluid inlet / outlet holes. Alternatively, instead of forming the uneven surface, a groove (not shown) may be formed so as to connect the fine holes 6a. A heat source 6b is buried between the fine holes 6a, 6a to heat the entire heating member by the heat source 6b. As the heat source 6b, an electric heater, steam, or heat medium oil can be used. A fluid supplied between the support member 5 and the sheet 4 is a fluid supply member 11 for supplying a fluid such as a liquid such as water or oil or a gas such as steam or compressed air. And a fluid supply / discharge device.

When the fluid is supplied from the fluid supply member 11 through the supply path 11a, the fine holes 6a,.
The fluid is further discharged, and the sheet 4 expands to a pressurized state. On the other hand, when heating the sheet 4, the sheet 4 and the heating member 6 are formed through the fine holes 6 a,.
Is discharged from the fluid discharge member 7 through the discharge path 7a, and the sheet 4 is attracted to and brought into contact with the heating member 6,
The sheet 4 can be heated by heat conduction.

The support member 5 can be moved up and down with respect to the transfer object 1 of the mounting table 2 by a driving member (not shown).

According to the above configuration, as shown in FIG. 1, the planar shape of the upper surface 2c surrounded by the wall 2b of the mounting table 2 and surrounded by the transfer material supporting members 2d,. The transfer object 1 having a substantially rectangular shape is placed. In this state, each transfer material supporting member 2d is opposed to each corner of the transfer receiving body 1, and the design layer 3 of the transfer material 3 to be transferred is formed.
a is opposed to the transfer-receiving body 1 via the adhesive layer.
At this time, the sheet 4 is discharged from the fluid discharge member 7 so that substantially the entire surface of the sheet 4 is adsorbed on the surface of the heating member 6, and the heat source 6 b of the heating member 6 contacts the heating member 6 with the heat source 6 b. Are directly heated by heat conduction.
Then, as shown in FIG. 2, the support member 5 is lowered to be in pressure contact with the wall 2 b of the mounting table 2 via the sheet 4 and the transfer material 3, and a part of the sheet 4 is brought into contact with the transfer material 3. Then, a part of the transfer material 3 is brought into contact with the transfer object 1. Next, as shown in FIG. 3, a fluid is ejected from the fluid supply member 11 through the fine holes 6a,..., 6a of the heating member 6 between the support member 5 and the sheet 4, so that the sheet 4 is expanded by the heating member 6. Then, the sheet 4 is pressurized, and the transfer material 3 is pressed together with the sheet 4 against the upper surface of each transfer material support member 2d and the upper surface of the transfer-receiving member 1 to form the sheet 4 and the transfer material support member 2d.
The sheet 4 and the transfer material 3 are sandwiched between the sheet 4 and the transfer material 3 while a part of the transfer material 3 facing the corner portion of the
The pattern layer 3a of the transfer material 3 is transferred onto the three-dimensional surface of the transfer object 1 by the heat and the pressure of the fluid transmitted from the sheet 4 while conforming to the three-dimensional shape of the upper surface. At the time of this transfer, the suction member 12 sucks a fluid, for example, a gas between the transfer object 1 and the transfer material 3 from the suction holes 2a,..., 2a of the mounting table 2 so that the design layer 3a of the transfer material 3 is bonded. It can be brought into close contact with the surface of the transfer object 1 via the layer. Next, after the fluid is extracted from the fluid discharge member 7 and substantially the entire surface of the sheet 4 is brought into contact with the heating member 6, the support member 5 is raised as shown in FIG. Then, as shown in FIG. 5, the delivery roller 8 and the take-up roller 9 are driven to peel off the release sheet 3b on which the design layer 3a has been transferred to the transfer-receiving body 1 from the surface of the transfer-receiving body 1. 9, and the next design layer 3 a to be transferred is positioned above the mounting table 2. In this state, the release layer peeled off from the release sheet 3b and the transfer pattern 1
3 are transferred and adhered via the adhesive layer. This release layer functions as a protective layer for the design layer 3a.

According to the above embodiment, the heated sheet 4 is brought into contact with the transfer material 3 and the transfer target 1
When the transfer material 3 is moved along the transfer material 3, a portion of the transfer material 3 corresponding to a corner portion of the transfer material 1 is sandwiched between the transfer material support member 2 d and the sheet 4, so that the transfer material 3 The transfer material 3 is reliably transferred to the transfer-receiving member 1 while effectively preventing wrinkles from being formed on a portion facing the corner portion. That is,
As shown in FIG. 8, by providing the transfer material support member 2d on the mounting table 2, a part of the transfer material 3 between the upper surface of the transfer material support member 2d and the sheet 4, that is, the transfer object Since the portion 3e facing the corner portion 1a of the transfer member 3 can be supported, the portion 3e of the transfer material 3 facing the corner portion 1a of the object 1 is pressed by the transfer material supporting member 2d and the sheet 4. Then, the transfer material 3 is made to extend along the corner 1a of the transferee 1 by utilizing the elongation of the transfer material 3 in a state where the corner-facing portion 3e of the transfer material 3 is positioned at a predetermined position before extending. Thus, the transfer material 3 can be more reliably moved along the transfer target 1. In other words, as shown in FIGS. 9 and 10, when no portion 3 e of the transfer material 3 that faces the corner 1 a of the transferee 1 is supported, the portion near the corner 1 a of the transferee 1 during transfer is not supported. Large wrinkles are generated on the transfer material 3 on the side surface, or the transfer material 1
Beautifully bent portion 3 of transfer material 3
10, f is not formed as shown in FIG. 10, and the wrinkles are complicatedly formed, so that the transfer material 3 cannot follow the corner portion 1a of the transfer target body 1 neatly, and there is a problem that transfer cannot be performed in this portion. It is.

Therefore, according to the above embodiment, the transfer target 1
Even if the surface of the object has a three-dimensional shape,
a, the sheet 4 and the transfer material 3
It can conform to the three-dimensional shape, particularly the corner 1a,
The design layer of the transfer material 3 can be easily and reliably transferred to the transfer target 1 having a dimensional shape. Therefore, for example, the sheet 4 and the transfer material 3 are not limited to those having the sharp corners 1a of the transfer object 1 but also contact the transfer object 1 on which the radius is formed. The pattern layer of the transfer material 3 is also beautifully and reliably transferred to the round portion. In addition, even if the transfer object 1 has a concave portion or the like, the transfer material 3 can be brought into close contact with the wall surface in the concave portion by sucking the gas in the concave portion with the suction member, so that clear transfer can be performed on the concave portion. I can do it.

As a method of transferring a three-dimensional shape of a transfer object with a transfer material, there is an in-mold transfer method.
In the in-mold transfer method, since the transfer material is previously inserted into the molding die, there is a disadvantage that the arrangement of the transfer material is restricted or the molding die becomes complicated. There are no such drawbacks.

According to the above embodiment, when the sheet 4 is heated, the fluid is discharged from the fluid discharging member 7 and the sheet 4 is heated.
, 6b is adsorbed to and brought into contact with the heating member 6, and in this state, the heat sources 6b,..., 6b of the heating member 6 are directly heated using heat conduction, so that the radiant heat of the heat source is used. Thus, the sheet 4 can be heated more efficiently than when the sheet 4 is heated. Also, since the surface of the heating member 6 is roughened as an uneven surface or a large number of grooves 6c are formed,
The attraction force of the sheet 4 to the surface of the heating member 6 can be improved, and the sheet 4 does not easily become loose. Further, a wall 2b surrounding the transfer target 1 is formed on the mounting table 2, and the support member 5 and the mounting table 2 are pressed against each other via the sheet 4 and the transfer material 3 at the time of transfer, so that the transfer target of the mounting table 2 is transferred. The mounting portion is kept closed so that the sheet 4 can be pressed against the surface of the transfer object 1 by the pressurizing action, and the suction member 12 allows the transfer object to be transferred from the suction holes 2a,. Since the fluid between the transfer material 1 and the transfer material 3 is sucked to prevent the extra gas from entering between the transfer material 3 and the transfer material 1, the surface of the transfer material 1 has a three-dimensional shape. Also, the sheet 4 and the transfer material 3 can be made to conform to the three-dimensional shape of the transfer object 1, and the pattern layer 3a of the transfer material 3 can be more easily and reliably transferred to the transfer object 1 having the three-dimensional shape. be able to.

The present invention is not limited to the above embodiment, but can be implemented in various other modes.

For example, as shown in FIG. 7, the transfer material supporting member 2d may be constituted by a wall portion 2e surrounding the entire periphery of the object 1 to be transferred.

When the transfer material 3 is in the form of a strip, the transfer material support member 2d serves as a positioning member for the transfer material 3 with respect to the transfer object 1. Instead of being sandwiched between the sheet 4 and the transfer material supporting member 2d, the transfer material 3 may be supported by the transfer material supporting member alone, that is, only by the support portion.

The heating member is not limited to a plate-like member fixed to the lower surface of the support member 5, but may be composed of heaters 16 fixed to the bottom surface of the container body 5a as shown in FIG. . In this modification, the mounting table 2 has a wall 2b.
Is formed, the transfer object 1 enters the support member 5 so that the transfer material 3 and the sheet 4 are pressed against the surface of the transfer object 1 by the fluid pressure.

As shown in FIG. 12, a first auxiliary table 30 as a first auxiliary member is provided between the transfer target 1 and the mounting table 2.
May be arranged so that the transfer material 3 can follow the transfer material 3 neatly to the end of the transfer object 1 on the mounting table side. That is, the first auxiliary table 30 has a planar shape smaller than the planar shape of the transfer target 1, and the side surface 30 a is recessed from the side surface 1 b of the transfer target 1. Therefore, the side surface 30a of the first auxiliary table 30 is
Since the transfer material 3 is disposed on the center side of the transfer object 1 with respect to the transfer member 3, the transfer material 3 can surely contact the end of the transfer object 1 on the mounting table side, and transfer can be performed more reliably. In other words, when the transfer target 1 is directly placed on the flat mounting table 2 without the first auxiliary table 30, the end of the transfer target 1 on the mounting base side as shown in FIG. There is a strong tendency that a gap 35 is formed between the transfer material 3 and the transfer material 3, which causes a problem that the transfer material 3 is difficult to be transferred cleanly at the end of the transfer object 1 on the mounting table side. However, according to this embodiment, such a problem can be effectively solved. The first auxiliary table 30 may be formed integrally with the mounting table 2 instead of being separately formed.

As shown in FIG. 14, when the transfer object 31 is thin and has a concave portion 31b on the lower surface, the second auxiliary table 32 fitted into the concave portion 31b is attached to the mounting table 2. The second auxiliary table 32 is arranged, and the second auxiliary table 32 communicates with the suction holes 2a,.
, 32a. In this modification, when the suction member 12 suctions the fluid between the transfer object 1 and the transfer material 3, the suction holes 2a,.
When a through-hole 31a is further formed in the transferred body 31 through the suction holes 32a,..., 32a of the second auxiliary table 32, the through-hole 31a faces the recess 31b of the transferred body 31 through the through-hole 31a. The fluid between the upper surface of the transfer body 31 and the lower surface of the transfer material 3 can also be sucked. Therefore, the second
The transfer material 3 can be brought into close contact with the surface of the transferred material 31 by the sheet 4 while supporting the thin transferred material 31 by the auxiliary table 32, and excess fluid between the transferred material 31 and the transfer material 3 can be provided. Can be reliably sucked, and the transfer of the transfer material 3 to the transfer target body 31 can be performed more reliably. In other words, if the second auxiliary table 32 does not have a suction hole, the transfer table 31 is made of a material having air permeability or the transfer table 31 has the hole 31a as described above. Thus, it is difficult to suck the gas between the transfer object 31 and the transfer material 3 even if suction is performed through the suction hole 2a. However, according to this variant,
Since the suction hole 32 a is formed in the second auxiliary table 32, even if suction is performed through the suction hole 2 a of the mounting table 2, the space between the transfer target body 31 and the transfer material 3 is transferred through the suction hole 32 a of the second auxiliary table 32. The gas can be sucked, and the transfer material 3 can be more securely brought into close contact with the transfer object 1.

As another modified example of the present invention, the same operation and effect can be obtained by moving the mounting table 2 up and down with respect to the support member 5.

The timing for supplying the fluid is such that the fluid is supplied before the sheet 4 comes into contact with the transfer material 3 so that the pressurized sheet 4 is brought into contact with the transfer material 3, and the fluid is supplied through the transfer material 3. May be pressed against the transfer receiving member 1.

The timing of discharging the fluid may be such that the fluid is discharged after the sheet 4 is separated from the transfer material 3. Further, if the supplied fluid is heated, the heating efficiency is improved.

Further, the sheet 4 may be pressed through the transfer material 3 only to the area of the transfer object 1 to be transferred.

The transfer material 3 is not limited to the above-described structure, but may be of various structures.

For example, in the above embodiment, the release sheet 3b
When peeling, the release layer of the release sheet 3b was left on the design layer side and functioned as a protective layer. However, the release sheet was made up of a base film and a release layer to form a release sheet. The release layer may be peeled off from the design layer 3a by peeling off from the design layer 3a.
As such a release layer, a resin coating or a laminated film is preferable.

Further, as the transfer material 3, a release sheet made of a base film,
A release layer remaining on the design layer side when the release sheet is peeled off,
It may be composed of a design layer having an adhesive property and including a design. In this case, the design layer can function as an adhesive layer, and the structure of the transfer material is simplified by the absence of the adhesive layer.

The transfer material 3 is composed of a release sheet made of a base film, a release layer remaining on the design layer side when the release sheet is peeled off, and a design layer having no adhesiveness and containing a design. Then, before the transfer, the adhesive layer may be applied to the design layer of the transfer material, or the adhesive tape may be arranged on the design layer of the transfer material, and then the design layer may be transferred to the transfer target. In this case, a tacky adhesive or a water-based adhesive can be used as the adhesive, and transfer can be performed at a low temperature, thereby preventing thermal deformation of the transfer target. When the adhesive tape is used, there is an advantage that a heating operation is not required in the transfer step.

The transfer material 3 is composed of a release sheet made of a base film, a release layer remaining on the design layer side when the release sheet is peeled off, and a design layer having no adhesiveness and containing a design. Then, the design layer of the transfer material may be transferred to a transfer object on which an adhesive is applied or a transfer object on which an adhesive tape is disposed. Also in this case, a tacky adhesive or a water-based adhesive can be used as the adhesive, and the transfer can be performed at a low temperature, so that the thermal deformation of the transfer object can be prevented. When the adhesive tape is used, there is an advantage that a heating operation is not required in the transfer step.

In the above embodiment, the fluid supply member 11 and the fluid discharge member 7 are separately connected to the fine holes 6a of the heating member 6. However, both members 11, 11 are connected to one fine hole 6a. 7 may be connected and shared.

In addition to the transfer of the transfer material 3, the transfer device of the present invention can also be used for attaching a sticking material that does not peel off the base film.
