Description of the Related Art Conventionally, decorative boards having decorations such as pictures on a substrate surface of the decorative board by a direct printing method, a laminating method, a transfer method or the like have been used for various purposes. In this case, if the surface of the base material is flat, the decoration of the picture can be easily made, but the decoration of the pattern is applied to the uneven surface by a special device. For example, in the case of a columnar shape such as a window frame or a surface border material, the base material decorative surface is a two-dimensional unevenness (a shape having a curvature only in one direction (a direction perpendicular to the generating line or the height direction) like a cylinder). One applicable curved surface decoration technique is proposed in Japanese Patent Publication No. 61-5895. That is, the technology of the publication is a surface decoration method by a laminating method, in which a surface-coated sheet coated with an adhesive on one side is supplied, while the base material is horizontally conveyed at a speed synchronized with a supply speed of the surface-mounted sheet, and is installed side by side. While maintaining the state in which the end of the facing sheet is not adhered by the large number of holding jigs, the adhesive-applied surface side of the facing sheet is gradually pressed against the base material for each small area, and the It is to be adhered by heating to the material surface. This method is called a lapping method. Japanese Patent Application Laid-Open No. 5-139097 proposes a curved surface decoration technique applicable to the case where the surface unevenness is a three-dimensional unevenness such as an embossed shape (that is, a shape having a curvature in two directions like a hemisphere). Have been. That is, the technology of the same publication is a surface decoration method by a transfer method, a thermoplastic resin film is used as a support of a transfer sheet, and a release layer, a pattern layer, and an adhesive layer are sequentially provided on the support. A transfer sheet is placed on a substrate having a convexly curved surface, and is pressed from the back surface of the support with a rubber heat roll having a rubber hardness of 60 ° or less to transfer a picture, thereby obtaining a decorative plate. . Further, a foamed layer which foams by heat during transfer is provided between the support and the release layer, and the foaming is also utilized to follow the uneven surface of the substrate.

Not applicable to irregularities. In addition, the soft rubber roll is liable to be worn by the corners of the unevenness of the base material to be transferred. Also,
In a configuration in which the foam layer is provided on the transfer sheet, the transfer sheet becomes too complicated and expensive. In addition, it is limited to a flat substrate as a whole.

A further description will be given using the apparatus of FIG. 1 described above. First, the base material 1 having a plate-like shape whose surface to be transferred has an uneven surface is processed one by one by the base material transfer device 2.
Conveyed inside. On the other hand, as the transfer sheet 3, a sheet in which a transfer layer composed of a decorative layer and a heat-sensitive adhesive layer is sequentially laminated on a support made of a thermoplastic resin film is used. The tension is applied by the sheet feeding device 4, and the transfer sheet 3 is unwound from the supply roll set in the sheet supply device 7, and enters the chamber 16 of the pressure applying unit 6 via the guide roller 8. In the chamber 16, the transfer sheet 3 is sandwiched at both ends in the width direction by the sheet support device 9,
The adhesive layer is conveyed at a constant speed in parallel with the conveyed base material 1 with a slight space opened above the base material 1 so as to face the side of the adhesive layer facing the conveyed base material 1 side. In the apparatus shown in the figure, a heating device 19 in the chamber 16 of the pressure applying unit 6 is provided.
By preheating the transfer sheet 3 before the application of the collision pressure, the extensibility of the sheet and the activation of the heat-sensitive adhesive layer are also performed. At the same time, the transfer surface of the base material 1 located below the transfer sheet 3 is also heated, and the adhesion is facilitated by the adhesive layer. Thus, the thermal bonding by the adhesive layer of the transfer sheet is smoothly performed.

を残して密着しない様にするための一つである。Next, the transfer sheet 3 is exposed to the collision of the solid particles 5 ejected from the nozzle 15 together with the air flow.
A large number of nozzles 15 are arranged linearly in a direction (= width direction) perpendicular to the transfer direction of the transfer sheet 3 and the base material 1 and perpendicular to the back surface of the transfer sheet. Is to apply the collision pressure to the transfer sheet on the support side of the transfer sheet in a linear band shape in the width direction over substantially the entire width of the transfer sheet 3 .
Et al. Is applied. The solid particles 5 ejected from the nozzle 15
Progresses in the direction of the transfer sheet 3 while spreading somewhat,
The solid particles also collide with the region between the plurality of nozzles 15. Then, the transfer sheet 3 which is conveyed in a floating manner with a gap with respect to the base material 1 by the collision pressure of the solid particles is pressed against the base material 1 and further into the concave portion of the uneven surface of the base material 1. When the transfer sheet is extended and deformed, the transfer sheet follows and adheres to the uneven surface shape of the substrate 1.
Note that the substrate 1 used in the description here is a plate material having an uneven surface, and is a flat plate material as a whole, and the transfer sheet 3 has both ends in the width direction by the sheet supporting device 14. In the state where nothing is done without applying the collision pressure, etc.
The close contact of the transfer sheet 3 with the base material 1 is performed earlier in the center in the width direction and later in the vicinity of both ends in the width direction. This means that, as a whole, the transfer sheet 3 and the substrate 1 are transported at the same speed and are successively exposed to collision pressure in the flow direction. This is one of the steps to prevent air from leaving close contact between the base material 1 and the transfer sheet 3 during the process.

It is conveyed toward the lower part of the chamber 16 to which the drain pipe 17 is connected. Then, it is sucked from the lower part of the chamber 16 by the drain pipe 17 and collected in the original hopper 12. Further, air used for ejecting solid particles and ejected from the nozzle 15 is also sucked by the drain pipe 17 and discharged out of the system by the vacuum pump 18. In this manner, the solid particles are prevented from flowing out to the surroundings together with the air from the opening of the entrance through which the transfer sheet and the base material enter and exit the chamber 16. At this time, it is preferable to set the pressure inside the chamber 16 lower than the outside in order to prevent the solid particles 5 from flowing out of the chamber 16.

As a result, a decorative plate 20 is obtained in which the decorative layer of the transfer sheet 3 has been transferred to the uneven surface of the substrate 1 via the adhesive layer. On the other hand, (the support of) the transfer sheet 3 after passing through the peeling roller 10 is transported obliquely upward and taken up by the sheet discharge device 11 as a discharge roll.

However, the present invention shows its true value when the surface to be transferred is an uneven surface, and particularly when the uneven surface is used. A substrate that is three-dimensional. Conventional holding jig that makes rotational contact (the aforementioned Japanese Patent Publication No. 61-5895).
Or a transfer roller made of rubber (see the above-mentioned JP-A-5-13909).
In Japanese Patent Application Laid-Open No. 7-207, the direction of the rotation axis is inherently limited, so that the applicable surface unevenness is limited to two-dimensional unevenness having a curvature only in one axial direction.
In the latter case, even if three-dimensional irregularities having a curvature in two axial directions are possible, the three-dimensional shape cannot be uniformly applied to an arbitrary direction. For example, unless the longitudinal direction of the wood grain conduit pattern is parallel to the feed direction of the transfer sheet, it cannot be successfully transferred to the concave portion of the conduit. Moreover, in the latter case, the shape of the base material is practically limited to a flat plate shape, and otherwise, it is impossible unless a transfer roll having a special shape tailored to each base material shape is used. However, as described above, in the present invention, since the collision pressure of solid particles that can behave fluidly is used, the direction of pressure application is essentially limited to the three-dimensional shape of surface irregularities. do not have. (The directionality is a direction of a temporal change of a point on the substrate to which the pressure is applied.) Therefore, even a substrate having a shape having irregularities in the transfer direction of the transfer sheet or the substrate. no I configuration. That is, it can be applied to two-dimensional irregularities having irregularities only in the feed direction or the width direction, and three-dimensional irregularities having irregularities in both the feed direction and the width direction. In addition, the point that the present invention does not have the above-mentioned directivity is considered in view of a method and an apparatus (the present invention may have such a form) in which a single-sheet transfer sheet is placed on a substrate and pressed and adhered one by one. , Easy to understand. Further, the base material is not limited to a flat plate material as a whole, and may be a base material having two-dimensional irregularities curved in the feed direction or width direction in a convex or concave shape in an arc shape, and a finer tertiary on the curved surface. There may be original surface irregularities. In the present invention, it is possible to arbitrarily decide whether to transfer the two-dimensional irregularities such as the arc shape of the base material in the width direction or the feed direction in consideration of workability and the like. It should be noted that the surface constituting the uneven surface is not limited to a flat surface, may be only a curved surface, or a combination of a flat surface and a curved surface. Therefore, the curved surface on the substrate to be transferred according to the present invention also means a concavo-convex surface having no curved surface composed of only a plurality of flat surfaces, such as a tooth profile of a clog. Further, the curvature in the present invention includes a case where the curvature is infinite (the radius of curvature = 0) which is angular like the periphery of a side or a vertex of a cube.

In order to apply to the three-dimensional uneven surface that demonstrates its true value,
At least at the time of transfer, a transfer sheet having stretchability is used. When the collision pressure of solid particles is applied due to stretchability,
The transfer sheet follows and adheres to the inside of the concave portion on the surface of the base material, and transfer is performed. The transfer sheet includes a support and a transfer layer that transfers and transfers. The transfer layer includes at least a decorative layer, and in a configuration in which an adhesive layer is further laminated, applying an adhesive to one or both of the transfer sheet and the base material during transfer can be omitted. The stretchability of the transfer sheet is mainly governed by the stretchability of the support. Therefore, if a rubber film is used as the support, without heating the transfer sheet or the like at the time of transfer due to the properties of rubber that is stretched at room temperature,
It is also possible to follow, adhere, and transfer to the uneven surface of the substrate. Also, if a thermoplastic resin film is used as the support, there is almost no extensibility at the time of forming the decorative layer, and at the time of transfer, as a transfer sheet that expresses sufficient extensibility by heating, as in the case of a conventionally known ordinary transfer sheet, A transfer sheet that can be used in the present invention can be prepared. In addition, in terms of stretchability, a biaxially stretched polyethylene terephthalate film, which has been widely used in the past, is required to exhibit necessary and sufficient stretchability by setting heating conditions and collision pressure conditions depending on the surface irregularities. Surface transfer is possible, but low-temperature, low-pressure, easy to develop stretchability.Polyolefin-based film such as polypropylene film, polyethylene film, polymethylpentene film, vinyl chloride resin film, nylon film, etc. Alternatively, a non-stretched film, a rubber (elastomer) film such as a natural rubber, a synthetic rubber, a urethane elastomer, and an olefin elastomer are also preferable supports.

However, the adhesive layer is not provided on the transfer sheet, but is provided on the transfer sheet by coating or the like immediately before transfer. Various forms, such as a method of providing an agent layer by coating or the like, or a method of providing an adhesive layer in advance or immediately before both a transfer sheet and a base material may be used. The method in which the adhesive layer is provided in advance only on the transfer sheet side has an advantage that it can be formed by printing or the like at the same time as the decoration layer, and that the time and equipment required for the transfer can be omitted. When the adhesive is applied to one or both of the transfer sheet and the base material immediately before, an adhesive such as a pressure-sensitive adhesive or a water-based adhesive may be used. When the substrate is porous, it is convenient to dry the solvent of the adhesive applied immediately before. In this case, it is possible to use a guide roller 8 having a large number of needles as the guide roller 8 of the transfer sheet feeder 4 to pierce the transfer sheet when passing the sheet, and to assist drying by the holes.
The diameter of the hole is usually about 0.1 to 1.0 mm, and the interval between adjacent ventilation holes is usually about 5 to 50 mm.

The heating means is optional, and as the heating means before the application of the collision pressure, for example, heater heating, infrared heating, dielectric heating, induction heating, hot air heating, etc., like the heating device 19 shown in the curved surface transfer device of FIG. It is. In the present invention, since the solid particles are used for applying pressure, the solid particles can be heated, and the solid particles can be used as a heating source for a transfer sheet or the like, and can be heated simultaneously with the close contact of the transfer. The heating of the solid particles means that the gas ejected from the nozzle together with the solid particles is also ejected by heating, and this gas is applied to the back surface of the transfer sheet (the surface on the support side).
By contacting the gas, gas can also be used as a heating source. Therefore, even when the transfer sheet or the like needs to be heated,
In the case where heating by solid particles or ejected gas is sufficient, a heating device for preheating can be omitted.

に密着することを防止できる。It is preferable to use a plurality of nozzles so that the collision area of the solid particles colliding with the transfer sheet has a desired shape. In the curved surface transfer device of FIG. 1, the transfer sheet and the base material are arranged in a line in a straight line at right angles to the feed direction of the transfer sheet to form a collision area in a band shape linearly in the width direction. For example,
FIG. 2A shows a configuration in which the collision areas are arranged in two rows in the feed direction in order to expand the collision area in the feed direction. FIG. 2 (b)
Although they are arranged in a line, the central part in the width direction is arranged to collide at the upstream side in the feed direction. In this arrangement, the transfer sheet is pressed against the base material from the center in the width direction and is sequentially pressed toward both ends in the width direction. With this configuration, it is possible to prevent the transfer sheet from adhering to the base material while holding the air in the center in the width direction.

い。The collision pressure of the solid particles does not need to be all uniform in the collision region. FIG. 3 shows an example in which a mountain-shaped pressure distribution is set such that the maximum collision pressure is at the center in the width direction and the collision pressure decreases toward both ends in the width direction. The setting of the collision pressure is based on the opening / closing amount of the valve, the size of the inside diameter of the pipe that transports the solid particles connected to the valve, and the pressure regulator (regulator).
By adjusting the gas pressure immediately before the nozzle using, for example, the control is performed by controlling the speed of the solid particles and the gas flow ejected from the nozzle. Setting the pressure distribution as shown in FIG. 3 produces an effect similar to the effect of FIG. 2B described above. In the conventional curved surface transfer method using a rubber transfer roll, if the diameter of the center portion of the transfer roll is increased, the center portion can be strengthened in terms of pressure, but the circumferential length differs between the center portion and both end portions. Sisters,
The transfer sheet is not uniformly fed due to pressure applied upon contact.

りする事が好ましい。In the curved surface transfer apparatus illustrated in FIG. 1, the nozzles are arranged horizontally in one example because the base material is flat. This is an arrangement in which solid particles collide perpendicularly to the transfer surface of the substrate. The collision is caused vertically because basically the collision pressure can be utilized most effectively. Therefore, for example, as shown in FIG. 4, if the transfer surface of the base material 1 (the cross-sectional shape perpendicular to the transport direction) is a convexly curved surface, a plurality of nozzles are prepared. The nozzle is preferably arranged perpendicularly to the surface of the object to be transferred so that the solid particles collide substantially perpendicularly with the collision surface. In this way, the nozzle arrangement should be adjusted so that the solid particles collide with the solid particles as perpendicularly as possible according to the uneven shape of the target substrate. The nozzle ejects solid particles together with the gas flow, and has a hollow cylindrical shape, a polygonal column shape, a fish tail shape or the like, for example. The nozzle may have a single opening, or may have a honeycomb (honeycomb) -shaped interior. The spray pressure is usually 0.1 ~
It is about 1.0 kg / cm 2 . In addition, when the solid particles are conveyed and collide with the transfer sheet, the solid particles, the transfer sheet, or the substrate may be charged. Therefore, in order to prevent charging, the nozzle 15, the drain pipe 17 and the like are grounded, the charge removing bar is brought into contact with the transfer sheet, or ions having a charge for neutralizing the charged charge are mixed into the airflow. Is preferred.

and m 2 is applied. Further, as a transfer sheet, a polypropylene film having a thickness of 50 μm is used as a support, and a pigment composed of carbon black, red iron oxide, titanium white, and graphite, an acrylic resin, and a vinyl chloride-vinyl acetate copolymer resin are used. A transfer layer was prepared by successively performing gravure printing of a brick-like pattern as a decorative layer and a 10 μm heat-sensitive adhesive layer made of a vinyl chloride-vinyl acetate copolymer resin as a decorative layer. Next, using the apparatus shown in FIG. 1, the base material was placed horizontally with the uneven surface facing up, and the transfer sheet was placed with the adhesive layer surface down.
Then, preheating the transfer sheet and the substrate in the radiant heat by the heating wire heater from the support side of the transfer sheet, ejected as the solid particles of nylon beads spherical particle size distribution 0.2~0.8mm from a nozzle with air at room temperature Back transfer sheet
The transfer sheet was pressed against the substrate by colliding with the (support side) . The spray pressure was 0.4 kg / cm 2 , and the pressure distribution of the air current was such that the center in the sheet width direction became maximum as shown in FIG.
Then, after the transfer sheet was extended into the concave portion of the joint and closely adhered thereto, the support of the transfer sheet was peeled off, and a decorative material was obtained. Further, an emulsion paint of polyvinylidene fluoride was applied to the surface of the transfer layer at a thickness of 10 μm to form a transparent protective layer, and a decorative material with a transparent protective layer was obtained.
