Description

This invention relates to a manufacturing device for decorative panels that manufactures decorative panels by attaching impregnated paper impregnated with a resin-based paint that has at least ultraviolet curing properties and is made into a biomass to the top surface of a base material through ultraviolet curing.

Conventionally, decorative boards are manufactured by attaching a decorative paper with a predetermined print to the surface of a wood fiberboard substrate such as particle board or MDF by heat and pressure (see, for example, Patent Document 1). At this time, impregnated paper is immersed in a tank filled with melamine resin to impregnate it with melamine resin, and the impregnated paper impregnated with melamine resin is layered on the top surface of the substrate and molded under heat and pressure at low pressure to produce low-pressure melamine decorative boards, and high-pressure melamine decorative boards with a thickness of about 1 mm are well known, which are made by layering only impregnated paper impregnated with melamine resin and kraft impregnated paper impregnated with phenolic resin and molding them under high pressure. These melamine decorative boards have a high upper surface hardness, excellent resistance to contamination, abrasion resistance, heat resistance, and water resistance, and are not easily scratched, so low-pressure melamine decorative boards are used for furniture materials and interior materials, etc., and thin high-pressure melamine decorative boards are used for furniture and door surfaces, shelves, counter surfaces, etc.

However, conventional decorative panels are made by impregnating, drying, and heat-pressing (180°C) petroleum-derived resins such as the melamine resin and phenolic resin mentioned above, which means that the manufacturing process consumes a huge amount of electricity and is also a cause of the microplastic problem. This goes against the spirit of the Sustainable Development Goals (SDGs) that have been called for in recent years, and is a factor that hinders the prevention of environmental destruction.

In addition, it is necessary to remove the melamine resin from the impregnated paper that adheres to it during heat and pressure, which is time-consuming, consumes a lot of electricity, and generates a lot of waste.

This invention was made in consideration of the above problems, and aims to make it possible to produce decorative panels cheaply and easily while reducing the use of petroleum-derived resins as much as possible, reducing power consumption and waste in the manufacturing process, and contributing to preventing environmental destruction.

In order to achieve the above-mentioned object, the manufacturing device for decorative boards according to the present invention is a manufacturing device for decorative boards that manufactures decorative boards by attaching impregnated paper that has been impregnated with resin and cured to the upper surface of a base material, the base material being made of a long wooden board that can be separated into predetermined lengths, and is characterized by being equipped with a conveying means for conveying the base material in the longitudinal direction, a pressurizing means having a main roller on the upper side and a slave roller on the lower side that pressurizes the impregnated paper unwound from the impregnated paper roll while it is superimposed on the upper surface of the base material, a paint supplying means that supplies a resin-based paint having a viscosity with at least ultraviolet curing properties to the upper surface of the base material across the width of the base material at a position immediately before the impregnated paper is superimposed on the upstream side of the pressurizing means, and impregnates the impregnated paper with the paint while applying pressure by the rotation of the main roller and the slave roller of the pressurizing means, a restricting means that restricts the paint supplied by the paint supplying means from spreading beyond the width of the base material, thereby keeping it within the width of the base material, and a curing means that cures the paint impregnated in the impregnated paper downstream of the pressurizing means.

With this configuration, the paint supplying means supplies a viscous resin-based paint with at least UV curing properties upstream of the pressure applying means that applies pressure to the impregnated paper while it is stacked on the top surface of the base material, just before the impregnated paper is stacked, and the curing means hardens the paint impregnated in the impregnated paper downstream of the pressure applying means. For example, by using an ultraviolet LED (wavelength 405 nm), the impregnated paint can be hardened with low power consumption to firmly bond the impregnated paper to the base material, which contributes to preventing environmental destruction without going against the spirit of the SDGs.

The regulating means prevents the paint supplied by the paint supply means from spreading beyond the width of the substrate, confining it to the width of the substrate, preventing the paint from spilling out beyond the width of the substrate and eliminating waste of paint. In addition, since the paint does not come into direct contact with the rollers of the pressure means, cleaning is not required when using a conventional coating machine such as a roll coater, and no waste such as waste liquid is generated. In addition, since the substrate is transported by the transport means while remaining long, the impregnated paper is bonded by the ultraviolet LEDs, so there is no need to use "adhesives" as in the past.

The apparatus further includes a lamination means provided downstream of the curing means for laminating a resin film on the impregnated paper impregnated with the paint, and a peeling means downstream of the lamination means for peeling off the resin film, the lamination means including a superimposition roller for superimposing the resin film unwound from a film roll on the top surface of the impregnated paper impregnated with the paint, a paint layer forming means for supplying a viscous resin paint having at least ultraviolet curing properties across the width of the substrate on the top surface of the impregnated paper at a position immediately before the resin film is superimposed on the upstream side of the superimposition roller to form a layer of the paint of a predetermined thickness on the top surface of the impregnated paper, another restricting means for restricting the layer of paint formed by the paint layer forming means from spreading beyond the width of the substrate and keeping it within the width of the substrate, and another hardening means for hardening the paint of the layer of paint formed by the paint layer forming means, and the peeling means preferably peels off the resin film while leaving the layer of paint formed by the paint layer forming means and hardened by the hardening means on the top surface of the impregnated paper.

In this way, downstream of the curing means, the overlapping roller of the lamination means laminates a resin film unwound from a film roll onto the impregnated paper that has been impregnated with paint and cured, and the paint layer forming means supplies a viscous resin-based paint with at least ultraviolet curing properties across the width of the substrate onto the top surface of the impregnated paper just before the resin film upstream of the overlapping roller is overlapped to form a layer of paint. After the paint of the paint layer is cured by another curing means, the resin film is peeled off by the peeling means while leaving the layer of cured paint on the top surface of the impregnated paper, so that the paint layer laminated on the top surface of the impregnated paper impregnated with paint can be finished to a mirror finish, and a mirror-finished decorative panel can be easily formed. In addition, if the paint layer side of the resin film is made rough, a decorative panel with a matte surface instead of a mirror surface can be formed, and decorative panels with excellent design and usable for various purposes can be easily produced.

It is also preferable to further provide a printing means provided between the pressure means and the lamination means for printing a predetermined pattern on the impregnated paper impregnated with the paint. In this case, the printing means can perform the desired printing between the pressure means and the lamination means, so there is no need to change the impregnated paper roll to a new design, and even if a design change occurs, it is possible to quickly respond to small lot orders, which is inexpensive and efficient.

It is also preferable that a plurality of sets of the laminating means and the peeling means are arranged in series in the direction of conveyance of the substrate by the conveying means. In this way, a decorative board having a plurality of laminated layers of paint can be formed, and a decorative board that is comparable to existing low-pressure melamine decorative boards in terms of abrasion resistance, heat resistance, water resistance, etc. can be formed.

In addition, the thickness of at least one of the paint layers formed by the paint layer forming means of the multiple sets of lamination means may be made different from the others. In this case, by changing the thickness of the paint layer, decorative panels with mirror surfaces suitable for various applications can be formed.

It is also preferable to further provide a separation means that is provided downstream of the peeling means and separates the base material at the predetermined length. In this way, by appropriately separating the long base material, a decorative panel suitable for the intended use can be easily formed.

It is also desirable that the paint be more than 50% biomass. This will reduce electricity consumption and the amount of petroleum-derived resin used, making it possible to provide environmentally friendly manufacturing processes and products, which is in line with the spirit of the SDGs.

According to the present invention, by using a resin-based paint having at least ultraviolet curing properties, the paint can be cured with low power consumption, for example by using ultraviolet LEDs, and this contributes to preventing environmental destruction without going against the spirit of the SDGs. Furthermore, the regulating means can confine the paint supplied by the paint supplying means to the width of the substrate, preventing the paint from overflowing beyond the width of the substrate and eliminating waste of paint. In addition, since the paint does not come into direct contact with the rollers of the pressure means, a production line that does not produce waste can be realized.

1 is a schematic diagram of an embodiment of a manufacturing apparatus for a decorative board according to the present invention; FIG. 2 is a perspective view of a portion of FIG. 1; 2 is a flowchart illustrating the operation of FIG. 1 .

One embodiment of the decorative panel manufacturing apparatus according to the present invention will be described with reference to Figures 1 to 3.

The manufacturing device 1 for decorative boards in this embodiment is configured as shown in FIG. 1. In FIG. 1, 2 denotes a substrate in which a particle board (PB) of a predetermined length is connected in a long length without any gaps between the substrates, 3 denotes a conveying means consisting of a plurality of conveying rollers 4 for conveying the substrate 2 in the direction of the arrow in FIG. 1, 5 denotes an impregnated paper roll 6 having approximately the same width as the substrate 2 and wound with printable titanium paper or other impregnated paper 6, and 7 denotes a first pressing means (hereinafter also referred to simply as "pressing means"), which is disposed below the impregnated paper roll 5 and includes a main roller 7a on the upper side and a sub roller 7b on the lower side, which press the impregnated paper 6 unwound from the impregnated paper roll 5 with a predetermined pressure from above and below while overlapping it on the upper surface of the substrate 2 being conveyed. Here, the axial length of both rollers 7a and 7b is set to be greater than the width of the substrate 2 as shown in FIG. 2.

In FIG. 1, 10 denotes a first paint supply means (hereinafter, simply referred to as "paint supply means"), which includes a paint tank 11 filled with a viscous resin-based paint that has both UV-curing and moisture-curing properties, and includes a plurality of supply pipes 12, one end of which is connected to the paint tank 11 and the other end of which is located upstream of the main roller 7a of the first pressure means 7, and supplies the paint in the paint tank 11 across the width of the substrate 2 to the top surface of the substrate 2 just before the impregnated paper 6 upstream of the first pressure means 7 is overlapped.

Here, the resin-based paints mentioned above are those that are 50% or more biomass-based, such as acrylic resins, vinyl acetate resins, latex resins, rubber resins, vinyl urethane resins, urethane resins, and various modified versions of these resins, as well as combinations of these resins with urea-melamine resins, epoxy resins, phenolic resins, isocyanate resins, etc.

Resins with UV-curing properties are mainly composed of oligomers or polymers such as polyester acrylate, epoxy acrylate, urethane acrylate, and polyether acrylate, either alone or in mixture, with an appropriate amount of reactive monomer added, and preferably contain a photopolymerization initiator to convert the active energy rays into ultraviolet rays.

As a resin having moisture curing properties, isocyanate compounds are mainly suitable. Specific examples of isocyanate compounds include isocyanate monomers such as hexamethylene diisocyanate, isophorone diisocyanate, tolylene diisocyanate, diphenylmethane diisocyanate, xylylene diisocyanate, and norbornene diisocyanate, as well as polyisocyanate derivatives such as biuret, isocyanurate, and trimethylolpropane adducts of these, and block products of these isocyanate monomers or polyisocyanate derivatives.

Returning to Figure 1, 14 is a first regulating means (hereinafter also simply referred to as the "regulating means") that regulates the paint supplied by the paint supply means 10 from spreading beyond the width of the substrate 2, thereby keeping it within the width of the substrate 2. As shown in Figure 2, it comprises regulating plates 15, 15 that are arranged upstream of the main roller 7a of the first pressure applying means 7 and placed on both ends of the substrate 2, and whose downstream arc-shaped end faces are installed along the peripheral surface of the main roller 7a, and both regulating plates 15, 15 are spaced apart at a distance narrower than the width of the substrate 2, with the distance being variable, and a paint reservoir 16 is formed in the area surrounded by the substrate 2 upstream of the main roller 7a, both regulating plates 15, 15, and the impregnated paper 6 superimposed on the substrate 2. Viscous resin-based paint supplied from the paint tank 11 accumulates in this paint reservoir 16, and the rotation of the main roller 7a of the first pressure means 7 in the direction of the arrow in Figures 1 and 2 causes the paint to adhere to the underside of the impregnated paper 6 across the width of the substrate 2. With the paint applied to the underside of the impregnated paper 6, the pressure applied by both rollers 7a and 7b of the pressure means 7 is controlled, so that the paint applied to the underside of the impregnated paper 6 spreads across the width of the impregnated paper 6 and substrate 2, allowing the paint to be uniformly impregnated.

In addition, in FIG. 1, 17 is a curing means equipped with an ultraviolet LED, which simultaneously cures the paint impregnated in the impregnated paper 6 downstream of the first pressure means 7 and the paint between the substrate 2 and the impregnated paper 6, and 18 is an inkjet printer, which is a printing means, and is installed downstream of the pressure means 7 and above the substrate 2, and prints a predetermined pattern on the impregnated paper 6 layered on the substrate 2 being transported. At this time, by printing using ultraviolet-curable biomass ink, the ultraviolet ink is cured by ultraviolet irradiation from, for example, a 405 nm ultraviolet LED built into the inkjet printer 18, and the predetermined pattern is printed on the impregnated paper 6.

In FIG. 1, 20 is a PET film roll on which a transparent PET film of a predetermined thickness, which is a resin film, is wound, and 21 is a second pressure means (hereinafter also simply referred to as "pressure means"), which is disposed below the PET film roll 20 and includes a main roller 21a on the upper side and a secondary roller 21b on the lower side, which are superimposing rollers that apply a predetermined pressure from above and below to superimpose the PET film 22 onto the impregnated paper 6 while the PET film 22 is being unwound from the PET film roll 20 and superimposes it on the impregnated paper 6.

In FIG. 1, 24 is a second paint supply means (hereinafter also simply referred to as "paint supply means"), which, like the first paint supply means 10, has a paint tank 25 filled with a viscous resin-based paint that combines biomass-based UV-curable and moisture-curable properties, and has a plurality of supply pipes 26, one end of which is connected to the paint tank 25 and the other end of which is arranged upstream of the main roller 21a of the second pressure means 21, and supplies the paint in the paint tank 25 across the width of the substrate 2 to the top surface of the impregnated paper 6 on the substrate 2 just before the PET film 22 is superimposed upstream of the second pressure means 21.

In addition, in FIG. 1, 28 is a second regulating means for regulating the paint supplied by the second paint supplying means 24 from spreading beyond the width of the substrate 2 and confining it to the width of the substrate 2. As with the first regulating means 14, as shown in FIG. 1, the second regulating means 28 is provided with regulating plates 29, 29 that are arranged upstream of the main roller 21a of the second pressurizing means 21 and placed on both ends of the substrate 2, and that are arranged so that the downstream arc-shaped end faces are aligned with the circumferential surface of the main roller 21a. The two regulating plates 29, 29 are spaced apart from each other at a distance narrower than the width of the substrate 2, and the distance between the two regulating plates 29, 29 is variable. A paint reservoir 30 is formed in the area surrounded by the substrate 2 upstream of the main roller 21a, the two regulating plates 29, 29, and the PET film 22 superimposed on the substrate 2. The second paint supplying means 24 and the second regulating means 28 constitute the "paint layer forming means" of the present invention.

The PET film roll 20, the main roller 21a and the driven roller 21b of the second pressure means 21, the second paint supply means 24, and the second regulating means 28 constitute a lamination means that is provided downstream of the first pressure means 7 and laminates the PET film (resin film) 22 onto the impregnated paper 6 impregnated with paint.

In FIG. 1, 32 is another curing means equipped with an ultraviolet LED for curing the layer of paint applied between the impregnated paper 6 and the PET film 22 downstream of the second pressure means 21, 33 is a peeling means arranged downstream of the curing means 32 and consisting of a peeling roller for peeling off the PET film 22 laminated on the impregnated paper 6 on the substrate 2, and 34 is a winding roller for winding up and recovering the PET film 22 peeled off by the peeling means 33.

In this case, by using a film with a flat lower surface that comes into contact with the impregnated paper 6 at a constant thickness as the PET film 22, the upper surface of the impregnated paper 6 overlaid on the substrate 2 can be finished into a mirror surface, and by using a film with a rough lower surface with fine irregularities that comes into contact with the impregnated paper 6 at a constant thickness as the PET film 22, the upper surface of the impregnated paper 6 overlaid on the substrate 2 can be formed into a matte surface rather than a mirror surface. In addition, if a predetermined design using irregularities or the like is applied to part of the mirror surface on the lower surface of the PET film 22, a design using irregularities or the like can be formed on the upper surface of the impregnated paper 6 overlaid on the substrate 2.

In FIG. 1, 36 is a separation means provided downstream of the peeling means 33, which includes a cutter that cuts the base material 2 with the impregnated paper 6 laminated thereon to a predetermined length, and an actuator that moves it up and down. The separation means 36 separates the base material 2 to a predetermined length to form a decorative board 37. Since the paint has moisture curing properties in addition to ultraviolet curing properties, in a humid environment such as Japan, by leaving the decorative board 37 as it is, the paint can be naturally cured to 100% by moisture without being cured to 100% by the ultraviolet LEDs of the curing means 17, 32.

Next, each step in forming the decorative panel 37 will be described with reference to the flowchart in Figure 3.

As shown in FIG. 3, the gap between the substrate 2 is set to zero (step S1), the first paint supply means 10 applies paint having ultraviolet and moisture curing properties filled in the paint tank 11 to the top surface of the substrate 2 (step S2), impregnated paper 6 is placed on the substrate 2 to which the paint has been applied and pressurized from above and below by the first pressure means 7 to impregnate the impregnated paper 6 with the paint (step S3), the paint impregnated in the impregnated paper is cured by irradiating it with ultraviolet light from the ultraviolet LED of the curing means 17 (step S4), and a predetermined pattern is printed on the impregnated paper 6 laminated on the substrate 2 transported by the transport means 3 by the inkjet printer 18, which is a printing means (step S5).

Furthermore, the second paint supplying means 24 applies paint having ultraviolet and moisture curing properties filled in the paint tank 25 to the upper surface of the impregnated paper 6 laminated to the substrate 2 (step S6), and the PET film 22 is superimposed on the impregnated paper 6 on the substrate 2 to which the paint has been applied, and pressure is applied from above and below by the second pressure means 21 to adjust the thickness of the paint layer (step S7), and ultraviolet light is irradiated by the ultraviolet LED of the curing means 32 to cure the paint applied between the impregnated paper 6 and the PET film 22 (step S8).

Then, the PET film 22 is peeled off by the peeling means 33 (step S9), and the base material 2 with the impregnated paper 6 laminated thereon is separated to a predetermined length by the separating means 36 (step S10), forming a decorative plate 37 of a predetermined length and completing the series of steps.

Therefore, according to the above-mentioned embodiment, the first paint supplying means 10 supplies a resin-based paint having a viscosity that combines ultraviolet curing properties and moisture curing properties and is biomassified (e.g., 50% or more biomassified) at a position upstream of the first pressurizing means 7 that pressurizes the impregnated paper 6 while it is stacked on the top surface of the base material 2 and just before the impregnated paper is stacked, and the curing means 17 cures the paint impregnated in the impregnated paper 6 downstream of the first pressurizing means 7. The paint can be cured with low power consumption by irradiating ultraviolet rays from the ultraviolet LED of the curing means 17. In addition, the paint can also be cured by moisture in the atmosphere. In addition, the paint can also be cured by moisture inside the base material 2, inside the impregnated paper 6, and in the atmosphere, which contributes to preventing environmental destruction without going against the spirit of the SDGs.

The regulating means 14, 28 can restrict the paint supplied by the first and second paint supplying means 10, 24 from spreading beyond the width of the substrate 2, and keep it within the width of the substrate 2, preventing the paint from spilling out beyond the width of the substrate 2 and eliminating waste of paint. Furthermore, since the paint does not come into direct contact with the main roller 7a of the first pressure means 7 or the main roller 21a of the second pressure means 21, there is no need to clean them, and no waste is produced, improving work efficiency. At this time, the impregnated paper 6 is bonded by the hardening of the paint while the substrate 2 is transported by the transporting means 3 in a long length, eliminating any room for the paint to leak out and more effectively preventing waste of paint.

In addition, downstream of the curing means 17, the main roller 21a constituting the laminating means laminates the PET film 22 unwound from the PET film roll 20 onto the impregnated paper 6 impregnated with the paint, and a viscous resin-based paint that combines UV-curing and moisture-curing properties is supplied across the width of the substrate to the top surface of the impregnated paper 6 just before the PET film 22 on the upstream side of the main roller 21a is laminated, forming a layer of paint. After the layer of paint is cured by another curing means 32, the PET film 22 is peeled off by the peeling means 33 while leaving the layer of cured paint on the top surface of the impregnated paper. This allows the paint layer laminated on the top surface of the impregnated paper 6 impregnated with the paint to have a mirror finish, and makes it easy to form a mirror-finished decorative panel 37.

In addition, if the paint layer side of the PET film 22 is made rough, it is possible to form a decorative board 37 that has a matte surface instead of a mirror finish, or a decorative board 37 that has a specific design using unevenness, making it easy to form a decorative board that has excellent design and can be used for a variety of purposes.

In addition, the curing means 17 equipped with ultraviolet LEDs is provided downstream of the first pressure means 7, the curing means 32 is provided downstream of the second pressure means 21, and the lamination means consisting of the PET film roll 20, the main roller 21a and the slave roller 21b of the second pressure means 21, the second paint supply means 24, and the second regulating means 28 is provided upstream of the curing means 32. This allows the paint to be cured almost 100% by the curing means 17, 32, which is very efficient. Furthermore, since the paint also has moisture curing properties, in a humid environment such as Japan, the paint can be naturally cured 100% by moisture by leaving the decorative board 37 alone, without having to be cured 100% by the ultraviolet LEDs of the curing means 17, 32.

The present invention is not limited to the above-mentioned embodiment, and various modifications can be made without departing from the spirit of the invention.

For example, in the above embodiment, the paint filled in the paint tanks 11 and 25 is one that has both UV-curable and moisture-curable properties, but it is also possible to use a paint that only has UV-curable properties.

In another embodiment, a plurality of sets of the PET film roll 20, the main roller 21a and the driven roller 21b of the second pressure means 21, the lamination means composed of the paint layer forming means consisting of the second paint supply means 24 and the second regulating means 28, and the curing means 32, which are enclosed by the dashed line in FIG. 1, may be provided in the conveying direction of the substrate 2.

In this case, by using a transparent PET film with unevenness on the paint layer side for the PET film roll 20 of the previous set, the PET film hardens after peeling off, making the paint surface rough, improving the adhesion and hardening of the paint in the next set. It is also possible to disperse distortion caused by cure shrinkage. Furthermore, by changing the thickness of the paint layer laminated in each set, it is possible to form a decorative panel 37 with a mirror surface or the like according to various applications.

In this way, a decorative board 37 can be formed by laminating multiple layers of paint, and a decorative board 37 that is comparable to existing low-pressure melamine decorative boards in terms of abrasion resistance, heat resistance, water resistance, etc. can be easily formed while contributing to preventing environmental destruction.

In addition, paints that have ultraviolet and moisture curing properties are not limited to those listed above, as long as they are 50% or more biomass-based.

In addition, instead of the PET film 22, other resin films that are transparent to ultraviolet light may be laminated.

The present invention can also be widely applied to manufacturing equipment for decorative panels, which manufacture decorative panels by impregnating the upper surface of a base material with a resin-based paint and attaching the hardened impregnated paper.
