For this purpose, the roller brush is configured as follows: instead of simply arranging the rotating shaft in parallel with the wood grain of the board to be surface-processed or the colored surface colored thereon in a fixed manner as in the conventional example, the rotating shaft is rotated at a high speed at a given inclination angle with respect to the left-right direction of the roller brush along the horizontal plane of the board at an arbitrary angle with respect to the conveying direction of the board by the rotating conveying rollers. Thus, the "contact" of the sheet material with the roller brush such as a metal brush is different between the left and right ends of the sheet material, and therefore, the grain or colored surface colored thereon is peeled off at different strengths on the left and right sides of the sheet material by the inclined roller brushes. This enables the floating (uzukuri) processing with a different design in the lateral direction of the plate material.)

Technical Field

The present invention relates to a Brushing machine (Brushing machine) for producing an old wood-style panel having a feeling of use, an old wood-style panel produced by the Brushing machine, and a method for producing the old wood-style panel. And more particularly, to a wiper for unevenly wiping the surface of a board to manufacture an old wood-style board having various wiping patterns and a natural feeling of use.

Background

Various kinds of panels are currently commercially available, which are painted with an old wood-style or antique-style appearance. In most of these exterior-coated panels that have been marketed, the surface thereof is subjected to surface finishing to obtain an old wood-like or antique-like texture. However, the "wear feeling" due to long-term use is not sufficiently exposed to the surface of the plate material, and therefore, the plate material has a defect that the surface state is not a true old wood-style or antique-style surface state.

In order to eliminate this drawback, for example, in japanese patent laid-open No. 9-155281, there is disclosed a "finish coating method" by which anyone can easily perform antique-style coating to exhibit a feeling of natural wear of corners or surfaces of furniture over the years of use. The polishing coating method comprises the following steps: comprises a step of applying a wiping filler to the surface of a surface-treated furniture, wiping the wiping filler with a rag while the wiping filler is not dried to fill the wood grain, and applying a color paint and a top coat in this order, followed by drying.

However, in this finish coating method, since the surface of the old wood style is exposed by wiping off a given paint with a wiper, the entire surface is flat, and the "worn feeling" is unnatural, and thus the antique feeling cannot be sufficiently exhibited. Further, the work is performed manually, which makes mass production difficult.

Further, japanese patent application laid-open No. 2007-175580 discloses a design property imparting method including a step of applying a design paint to a wall surface to which unevenness is imparted and a step of scraping off the wall surface with a rubber trowel (trowel). However, this method has a drawback that the natural antique feeling is poor because the paint is scraped off by the rubber trowel. The method of imparting design properties is a finish paint and a method of imparting design properties for creating a feeling of design within the business range of a masquerader, and a board based on mass production in the market in the wood industry according to the invention of the present application is not assumed.

Further, japanese patent application laid-open No. 2015-54518 discloses an antique wood material whose surface is finished to an old color tone and shape by applying a sizing process, instead of a substitute wood material having the same design as that of a sleeper for gardening. This antique wood is characterized in that the wood grain emerging from the brushing process is projected on at least one surface of the square wood subjected to the sizing process, and the respective surfaces are partially damaged by the brushing process, and the respective surfaces are further coated in black or brown to give an antique feeling. This method has a drawback that although a certain degree of antique feeling can be obtained by applying brushing to the surface and then applying coating, the coating is uniformly applied to the entire surface, and therefore, the method lacks a natural feeling of use and "wearing feeling", and cannot create a sufficient atmosphere of old wood.

In addition, in recent wood markets, antique American siding boards (trade name: stikwood) as shown in FIG. 5 are also sold. This is a relatively thin wall panel in which the wood grain of the late wood and the early wood is three-dimensionally protruded and the coating is roughly performed by a paint roller based on the three-dimensional protrusion, thereby showing the waste wood pattern and the natural feeling. The sheet material according to the invention may at first glance look similar to a sheet material having an antique surface feel. However, a painted surface which is only painted unevenly and roughly on every part of a wood grain is only a painting method such as painting, and has a defect of having a different hand feeling from the original old wood. In particular, the painted surface has no natural wear feeling, and therefore, the paint looks like artificial wood.

On the other hand, there has been a wood processing technique called floating (original: floating り) from the past in Japan. This is a technique of sufficiently highlighting the wood grains of the wood to impart a concave-convex feeling to the surface along the wood grains, thereby revealing the old wood-style or antique-style surface. That is, as the wooden material, a board or the like that is subjected to wood processing so that wood grains appear on the surface is used. The cross section of the wood grain is formed by alternately arranging early wood and late wood. The early wood is a part that grows in the period from spring to summer of one year, and the part grows fast, so that the wood grain texture is rough and soft, and generally has a light color. In addition, late wood is a part that grows from fall to winter of one year, and since it grows slowly, the texture of wood grain is dense and hard, and generally exhibits a color thicker than that of early wood. In the floating process, for example, as shown in japanese patent laid-open publication No. 6-238619, a surface of a wooden material is first sanded and polished, and then the floating process is performed. The floating process is performed with a floating machine similar to a so-called planer that rotates blades of a planer. That is, in this floating machine, the floating process is performed by passing a wooden material as a workpiece through a brushing machine formed of a roller brush such as a metal brush instead of a blade of a planer. That is, when the surface of the wooden material is strongly brushed and polished with a roller brush such as a metal brush, the surface of the early wood having a coarse and soft wood grain structure of the wooden material is greatly ground to form concave portions, but the surface of the late wood having a dense and hard structure is left as convex portions without being substantially cut, and the surface of the wooden material is subjected to the floating process by showing a feeling of unevenness.

In this example, after the surface of the wooden material is subjected to the floating process, the coloring agent is applied to the surface of the wooden material. As the colorant, a liquid colorant obtained by mixing a pigment or a dye with a liquid binder is used, and while the colorant is not dried after the colorant is applied, the colorant applied to the surface of the wooden material is scraped off by passing the wooden material through a reverse roller or the like, and then the colorant is dried. In this case, the scraping action strongly acts on the surface of the late material as the convex portion to remove a large amount of the colorant from the surface of the late material, so that the colorant hardly remains on the surface of the late material. In contrast, the scraping is not substantially applied to the surface of the early wood which becomes the concave portion, and the colorant is not substantially removed from the surface of the early wood and remains in a large amount. Therefore, the early wood is colored to be darker by the colorant, and the late wood is colored to be lighter to a degree that the coloring by the colorant is slightly left, so that the reversed shade difference between the early wood and the late wood is made clear by the coloring, whereby the wood grain can be made sufficiently conspicuous. In this way, the surface of the old wood or the antique can be exposed by the floating of the brush by the roller brush such as the metal brush instead of the blade of the plane. Surface processing techniques of old wood style or antique style similar in principle are also disclosed in japanese patent laid-open nos. sho 58-84709, 2013-91277, 2017-189943 and the like.

However, in the technique of exposing the old wood-like or antique-like surface by the floating technique using the conventional brush machine including the roller brush such as the metal brush, since the rotation shaft of the roller brush is disposed parallel to the surface of the wood, the contact surface of the roller brush with respect to the wood is uniform, and the uniformly contacted roller brush uniformly removes the wood grain of the wood or the coloring agent colored thereon. As a result, the appearance (design) of the wood surface is completely uniform in industrial or artificial appearance, and has a drawback of lack of variation. The lack of a designable appearance of the wood surface is likely to be a drawback in revealing old wood-style or antique-style surfaces. Therefore, there is a need for a wiper that can sufficiently expose the "wear" of a more natural long-term use to the surface of a plate material, thereby enabling the plate material to be processed into a real old wood-style or antique-style surface condition.

Further, japanese patent application laid-open publication No. 2011-5822 discloses a surface treatment apparatus and a surface treatment method capable of applying a wood grain pattern having high appearance quality. That is, in one roller brush, a plurality of annular brush bodies (14, 15, and 16 shown in fig. 4 of the drawing) are arranged adjacent to each other in the axial direction. The annular brush body is rotated to form a structure for applying a wood grain pattern on the surface of a molded product. However, even in this structure, as shown in fig. 2 of the cited example, the shaft of the roller brush is arranged in a position parallel to the surface of the molded article, and as a result, there is a drawback that the appearance design is monotonous in the manufacturing process.

Further, as the prior art most relevant to the invention of the present application, in Japanese Kokai Sho 56-42846 shown in the attached FIG. 8, a wire brush flossing sanding device is also disclosed. The two wire brush rolls are obliquely installed so that the axis of one wire brush roll intersects at an acute angle and the axis of the other wire brush roll intersects at an obtuse angle with respect to the feeding direction of a plate material as a workpiece. Since the direction of the plate grain is parallel/inverse grain depending on the grain on the plate surface, the two wire brush rolls are installed at different angles as described above in order to perform a good embossing process for any grain. However, in this configuration, the angle of each wire brush roller with respect to the feeding direction of the plate material is fixed, and each wire brush roller is fixedly disposed in a parallel position with respect to the horizontal plane of the plate material, and as a result, there is a drawback that the appearance design is complicated and the processing is monotonous.

Disclosure of Invention

Problems to be solved by the invention

The problem to be solved is that, in the conventional plate material, the painted surface has no natural wear feeling, and therefore, it seems to be a wood material which has been artificially treated. In particular, when a brushing machine is used to produce a wooden or antique panel by peeling off the painted surface of the panel or performing a floating process to expose the panel to a wearing sensation, the structure of the brushing machine is considered to be problematic. That is, the conventional brushing machine has a rotating shaft of a roller brush such as a metal brush built therein, which is simply arranged in parallel to the painted surface of the board to be surface-processed or the wood grain of the board, and thus is uniformly in contact with the entire surface of the board.

This has the drawback that the natural wear feeling is hardly revealed because the peeling process or the floating process is uniformly performed on the entire surface of the plate material.

Means for solving the problems

Therefore, in the wiper according to the present invention, the arrangement of the rotating shaft of the roller brush such as the metal brush is studied, and the rotating shaft of the roller brush is not simply arranged in parallel with respect to the colored surface or the wood grain of the plate material to be surface-processed as in the conventional example, but is arranged to be inclined to the left and right with respect to the left and right height of the surface of the plate material (example 1), or the roller brush is arranged at an arbitrary angle with respect to the conveying direction of the plate material by the rotating conveying roller (example 2). Thus, in example 1, the "contact" of the roller brush such as a metal brush with respect to the board can be made different between the left and right sides of the board, and further, in example 2, the contact of the brush can be made weaker on the lower side of the rotation where the roller brush is in rotational contact with the grain, i.e., on the rear side of the late wood, and the contact of the brush can be made stronger on the upper side of the rotation where the roller brush is in rotational contact with the grain, i.e., on the front side of the late wood. Therefore, the left and right of the coated surface of the plate material or the left and right of the rear material are brushed with different strengths by the inclined roller brush. That is, the coated surface is peeled off at different strengths, and the solid wood grain is given strength and then subjected to the embossing. Thus, the peeling process with different appearance designs can be performed in the left-right direction of the plate material. This does not result in uniform peeling by uniform "touching" of the sheet material as in the prior art roll brush, but rather reveals a more natural changing "scuff" and results in the production of a true wood-like or antique-like sheet material.

In the above configuration, the arrangement of the rotary shaft is configured to be able to change the actuator by, for example, manual operation based on the round shank and the screw fixing mechanism. That is, the arrangement of the rotating shaft is fixed according to the manufacturing lot of the old wood-style or antique-style sheet material. In the next manufacturing lot, the operator manually changes the arrangement of the rotary shafts, thereby enabling the peeling process with a different design. In yet another embodiment, instead of the manual operation, the height of the rotating shaft with respect to the surface of the plate material may be automatically set to be inclined by a predetermined actuator controlled by a program. With this configuration, the feeling of distance between the roller brush and the plate material can be changed more variably, and as a result, a natural feeling of abrasion rich in a change in peel strength is exposed on the surface of the plate material, whereby the plate material subjected to the surface finishing of old wood style or antique style as if it were the original can be manufactured. Such program control can be easily realized by a person skilled in the art by a conventional technique, and thus a detailed description thereof will be omitted.

Effects of the invention

In the conventional wiper shown in fig. 8, the following structure is adopted: a roller brush such as a metal brush is arranged parallel to the surface of a work material such as a plate material, and the roller brush is in uniform contact with the surface of the plate material. However, unlike the example, in the wiper of the present invention, the rotation axis is disposed at a height of the roller brush inclined to the left and right with respect to the surface of the plate material. In addition, the height of the roller brush can be changed arbitrarily. Further, the brush is touched differently between the front side and the rear side of the late material, so that the peeling treatment of the paint and the floating processing of the early material can be changed.

This makes the roller brush unevenly contact the surface of the plate material in the left-right direction, and makes the roller brush unevenly contact the surface of the plate material on the rear side and the front side of the rear material. Therefore, various changes can be made to the "touch" of the roll brush with respect to the surface of the sheet material. This has the following advantages: a more natural "wear feel" can be revealed on the surface of the board, as a result of which a more traditional old wood style board can be produced.

Detailed Description

An object of the present invention is to easily manufacture an antique-style panel having antique and plain colors and a contrast in color tone using a new wood material by brushing a part of a panel subjected to a predetermined painting process with a roller brush to locally perform paint peeling and float (uzukuri) processes. Next, the structure of the wiper for achieving this object is described in detail.

Fig. 1 is a conceptual diagram illustrating a structure of a wiper 1 according to the present invention. The basic structure is similar to a so-called planer according to the prior art. That is, the present invention is constituted by a fixed upper housing 100 and a movable lower housing 200 that can move up and down relative to the fixed upper housing 100. Further, the upper housing may have a vertically movable structure. The plate material 300 to be processed is sandwiched between the fixed upper housing 100 and the movable lower housing 200 in a vertical gap in a state where the plate material can advance and retreat by the rotation of the conveying rollers 10. The structure is the same as that of a common planer. The difference is that a roller brush 20 is rotatably supported by a bearing body 22 for holding the roller brush, instead of a planer tool of a planer, between the conveying rollers 10, 10 in the moving direction of the plate material. The roller brush 20 can be rotated at a high speed by a motor or the like not shown. The roller brush 20 may be, for example, a metal brush or a nylon brush. Can be freely replaced according to the purpose of brushing. By brushing the coated surface of the surface-coated plate material with the roller brush 20 rotating at a high speed, the coated portion is peeled off, and by brushing more strongly, the original plate material can be partially subjected to the float fabrication (uzukuri). In order to provide a change to the brushing, the brushing machine 1 according to the present invention is configured to be able to set the inclination of the roller brush shaft 21, which is the horizontal axis of the roller brush, to be different in height from the plate material 300 to the left and right of the shaft, which is different from the basic structure of the conventional planer. The setting of the brush shaft 21 described above is performed by controlling the posture of a brush shaft holding vertical rod 23 that vertically supports the brush holding bearing body 22 by a brush shaft control actuator 24.

Fig. 2 (a) and (B) are conceptual views relating to the angle setting of the roller brush 20 in the wiper 1 according to example 1 of the present invention. (A) The top view shows (a) and the sectional view shows (B) the wiper 1 at the roller brush shaft 20. Unlike the planer of the conventional example, the vertical rod guide plates 30 and 30 are provided on the side surface to which the upper housing 100 is fixed so as to protrude in a horizontally bilaterally symmetrical manner. Arc-shaped notches 31, 31 are provided in the vertical rod guide plates 30, 30. As shown in (B), the roller brush shaft 21 is rotatably held by the roller brush holding bearing bodies 22, 22. The bearing bodies 22, 22 for holding the roller brush are vertically held by vertical rods 23, 23 for holding the roller brush in the vertical direction. The vertical rods 23, 23 for holding the roller brush are inserted through the arc-shaped slots 31, and attitude control is performed by the actuators 24, 24 for controlling the roller brush attached to the lower surfaces of the vertical rod guide plates 30, 30. That is, in the present invention, the roll brush 20 is attitude-controlled by the roll-brush control actuators 24, 24 so as to maintain a right angle with respect to the conveying direction of the sheet material 300 as shown in (a), and so as to maintain a given inclination angle in the left-right direction with respect to the horizontal plane of the sheet material 300 as shown in (B). Therefore, the roller brush 20 does not contact the plate material 300 in parallel, but brushes only a portion of the plate material 300 (in this case, the right half of the plate material 300). The specific means for controlling the posture of the roller brush 20 by the roller brush control actuators 24, 24 is not essential to the invention of the present application, and therefore, a detailed description thereof is omitted, and any posture control means based on the conventional art may be used. For example, the inclination angle of the roll brush 20 in the left-right direction with respect to the horizontal plane of the plate material 300 can be controlled by engaging the screw threads provided in the roll brush holding vertical rods 23 and 23 in the circumferential direction with rotation of unillustrated rotation nuts of the roll brush control actuators 24 and 24. The inclination angle (in this example, the right angle) of the roller brush 20 with respect to the conveying direction may be controlled by engaging a concave portion provided on the inner periphery of the vertical bar guide plates 30, 30 with gear rotation (not shown) of the roller brush control actuators 24, 24. These controls may be manually operated by the operator of the wiper 1, or may be programmed by a CPU not shown. Since these can be controlled by the conventional technique, detailed description thereof will be omitted.

Fig. 3 (a) and (B) are conceptual views of the wiper 1 according to example 2 of the present invention. In the above-described embodiment 1, the inclination angle of the roller brush 20 with respect to the conveying direction is set at a right angle and a given inclination angle with respect to the left-right direction, but in this embodiment 2, as shown in (a), the roller brush 20 is set at a given inclination angle with respect to the conveying direction and, as shown in (B), is set horizontally with respect to the left-right direction. Further, the following structure is provided: the predetermined inclination angle with respect to the conveyance direction of the wiper 1 is adjusted by sliding the vertical rod for roller brush holding 23 along the arc-shaped notch 31 by the actuator for roller brush control 24. In this regard, the present invention is different from the structure in which the installation angle of each wire brush roller with respect to the plate material conveying direction is fixed as in the above-described patent document 9.

Next, how the roller brush 20 according to the above-described embodiments 1 and 2 and the plate material 300 as the workpiece function will be described. Fig. 4 (a), (B), and (C) are conceptual views showing contact portions between the roll brush 20 and the plate material when the inclination of the height of the roll brush shaft in example 1 is set to be different from left to right. The surface of the panel 300 is previously coated with a given coating 310. The coating layer may be a single layer or may be a plurality of layers to reveal a complex vintage feeling. In this case, as shown in (a), the roller brush 20 is set at a given inclination angle so as to be in inclined contact with the plate material 300 advanced and conveyed by the conveying roller 10. Unlike the conventional brushing machine, the roller brush 20 of the brushing machine 1 brushes only the right side of the plate material 300. Therefore, the roller brush 20 is only brought into contact with the right coating surface and brushing is performed. The degree of peeling of the coating 310 is determined by adjusting the conveying speed of the sheet material 300 and the contact strength of the roller brush 20 with the sheet material 300. The conveying speed and the contact strength may be set by manual operation, or may be programmed by the CPU. By peeling the coating layer 310 with the roller brush 20 to a given degree, a more natural "wearing feeling" can be revealed, so that an antique style sheet material with a more natural touch can be manufactured.

Further, as shown in (B), when the roller brush 20 brushes the plate material 300 for a longer period of time with a stronger contact strength, the paint is completely peeled off from the right side portion of the plate material 300, and the underlying base is subjected to the float-building 313(uzukuri) process. In this case, the relatively soft wooden part of the early wood material of the plate material 300 is easily subjected to the floating process by brushing with the roller brush 20. As a result, as shown in (C), the strip-shaped coated surface 320 is left on the left side of the plate material 300 by the roller brush 20, the inclined rotary brush peeled surface 330 in which the coated material portion is left in the strip shape in the longitudinal direction while continuously changing in the left-right direction in a gradual change is formed in the vicinity of the center portion, and the inclined rotary brush float surface 340 in which the coated surface is peeled off over the entire surface and the float process is performed is formed on the right side of the plate material 300. Note that, in this (C), the oblique-rotation brush peeling surface 330 should be illustrated as continuously changing in a gradation shape from the left side to the right side as described above, but in the electronic application of PCT, the gradation is not sufficiently expressed in (C) in the process of converting to the PDF file, but is displayed in white in its entirety. However, originally, the inclined rotary brush peeling surface 330 is formed in a band shape, the left side is formed with the coating surface 320 on which the coating material 310 is left thickly, the left side is formed with the inclined rotary brush peeling surface 330 on which a part of the coating material is peeled off, and then the inclined rotary brush buoying surface 340 is formed by performing the buoying process after the coating material is completely peeled off, and as a result, a surface appearance design is formed which is gradually changed from the left side to the right side of the plate material 300 to become thinner coating material 310.

The inclined rotating brush separation surface 330 and the inclined rotating brush floating surface 340 are both formed by the rotating operation of the linear roller brush 20 as shown in fig. 4 (a), (B), and (C), and therefore have the same inclination angle in the short side direction. By thus making "wear feeling" and "use feeling" deeper, the wooden plate 300 having a more natural antique feeling can be produced. Fig. 5 is a photograph showing a sample obtained by a partial peeling process in which an actual plate material 300 is coated with the roller brush 20. In this sample, white paint remained on the left side and paint was peeled off on the right side, resulting in a natural old wood-style sheet material having a "scuff feel". In addition, it will be appreciated that in this photograph, in addition to the wood grain extending in the longitudinal direction, a more complex "wear sensation" is revealed due to the so-called serrations extending in the transverse direction.

Next, (a), (B), and (C) of fig. 6 are conceptual views illustrating how the roller brush 20 according to example 2 acts on the plate material 300 as the workpiece. In this embodiment 2, the roller brush 20 is set to a prescribed inclination angle with respect to the conveying direction as shown in (C), and is set to be horizontal with respect to the right-left direction as shown in (B). Since the wood grains of the plate 300 in this figure mainly extend in the vertical direction, the contact with the brush on the left side of each of the illustrated nightwoods is weak to the "rear side of the nightwood" which is the downstream side of the hard nightwood with respect to the rotation direction of the roller brush 20 rotating clockwise at high speed. On the contrary, the roller brush strongly touches the "front side of the rear member" 315, which is the upstream side of the hard rear member, to the brush on the right side of each rear member in the figure, with respect to the rotation direction of the roller brush. Therefore, a coating material peeling surface is formed on the left side of each night material, from which only a part of the coating material (310) is peeled off, and a floating surface is formed on the right side of each night material, from which the coating material (310) is completely peeled off and further floated. Further, a coating material release surface and a floating surface are formed on the early wood 312 between the rear side 314 of the late wood and the front side 315 of the adjacent late wood, and they are continuously changed in a gradual change, thereby manufacturing an old wooden or antique-style panel 300 having a "wearing feeling". The strength of the paint residue/peeling or floating can be freely changed by setting the roller brush 20 at a certain inclination angle with respect to the conveying direction. In contrast, in the structure of patent document 9, since the installation angle of each wire brush roller with respect to the conveying direction of the plate material is fixed, the technical idea of freely adjusting the strength/weakness of the remaining/peeling or floating of the paint is lacking, and thus the structure is fundamentally different from that of embodiment 2.

In addition, in embodiment 3 in which the roller brush 20 is set to have an inclination angle with respect to the left-right direction and an inclination angle with respect to the conveying direction in combination with embodiments 1 and 2 described above, a more complicated "wear feeling" can be exhibited.

Industrial applicability

In the brush coater 1 according to the present invention, since the inclination angle of the roller brush 20 with respect to the left-right direction and the inclination angle of the roller brush 20 with respect to the feeding direction of the plate material can be arbitrarily set, the inclined rotary brush peeling surface 330 and the inclined rotary brush floating surface 340 having an arbitrary width can be formed in the left-right direction of the plate material 300 as the workpiece, and the coating material can be left on the "rear side of the late material" with respect to the rotation direction of the roller brush to an arbitrary degree or the floating processing can be performed to an arbitrary degree. In this way, by brushing, a natural "wearing sensation" can be revealed, and a more natural old wood-style panel can be manufactured.
