Description

{PAINTING DEVICE FOR PANELS}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a coating apparatus for a panel, and more particularly, to a coating apparatus for a panel, in which a panel is painted using a belt (a plate) And the time required for the panel can be saved.

In general, panels used for shelves, shelves, bookshelves, shelves or various sinks or workbenches for home or office use are mainly wood, synthetic resin panels or plywood which are cut from the wood. In the case of plywood, the fibers are extracted from wood, MDF (Medium Density Fiberboard) plywood mixed with a synthetic resin adhesive and compression molded.

Furniture products manufactured using MDF plywood for furniture products of about 90% or more are widely used not only as furniture but also as building materials, except for some expensive furniture products that are used as raw wood among furniture products manufactured in the recent years.

The wood panel made of wood is used by treating the surface of the wood panel such as the upper surface, the lower surface, the edge surface, etc. of the wood panel by painting the surface, bonding the sheet paper, and the like.

Most preferably, the surface of the wood panel is painted, but in the case of paint painting, it is difficult to paint such as overflow of paint against the edge surface. Automation is difficult due to such a problem, and even if automation is performed, there is a problem that the edge plane is limited to the edge plane and the curve edge is not automated.

Further, in order to add a predetermined image to the edge surface, there is a problem that a separate additional work such as a method of attaching a transfer film or sheet paper is required in order to form an image separately from the surface treatment.

MDF plywood is relatively cheaper than using wood, it is easy to store and it can be processed in various forms. It has the advantage of collecting processed and remaining crushed pieces and cutting pieces and making them as recycled plywood for reuse However, since the material of the inner part is soft, the edge surface exposed to the outside when the material is cut off has a high adsorption force for adsorbing moisture Is very high and when exposed to a small amount of moisture or moisture, it is swollen or corroded and oxidized like dust.

Therefore, the surface treatment for the cut edge surface of the wood board made of the MDF plywood is necessarily required, and the conventional surface treatment method will be described as follows.

Preferably, the edge face of the wood board is painted. The edge face of the wood board is first polished with sandpaper, the predetermined paint is firstly sprayed on the polished edge face by spraying, and then the edge face is dried . Then, the dried edge surface is secondarily polished with sandpaper, and then the predetermined paint is secondarily sprayed onto the edge surface by spraying.

The above-described method of applying the wood panel edge surface can obtain a high-quality wood panel with excellent coherence with the edge surface and the lower surface of the wood panel.

However, since the edge surface of the wood panel, in particular, the MDF plywood has a lower density than the upper and lower surfaces of the MDF plywood, there is a characteristic of high water absorbency that absorbs moisture, and when spray paint having a very low viscosity is sprayed on the edge surface, Since the edge surface absorbs a large amount of paint, there is a problem that the paint can not be uniformly applied to the edge surface.

In addition, when spraying paint on the edge surface, the efficiency is very low because the arrival rate is about 25 to 30%.

In addition, the arrival rate of the sprayed paint to the edge surface is only about 25 to 30%, and about 70 to 75% of the remaining dust must be collected by the dust collecting equipment. However, most small companies do not have the dust collecting equipment There is a problem that environmental pollution is caused.

In addition, in the case of spraying with a spray, since the paint is sprayed on the edge surface one by one by the human force, there is a problem that the production cost increases and the productivity decreases.

Related Prior Art Patent Application No. 10-0954445 entitled " Medium Density Fiberboard Edge Surface Finishing Apparatus ", Registered on Apr. 15, 2010) and Published Unexamined Patent Application No. 10-2005-0043842 Name of invention: Edge painting device of furniture panel, published on May 11, 2005).

1 to 4, a coating apparatus 100 for a panel according to the present invention includes a driving roller unit 110, a coating roller unit 120, a main trench 130, and a paint supply unit 140, .

The driving roller unit 110 is coupled to the existing driving motor, and is detachably coupled. The driving roller portion 110 has a cylindrical shape and is made of metal or plastic. The driving roller unit 110 rotates in the same direction as the conventional driving motor due to the rotational force of the conventional driving motor, but may rotate in the reverse direction in some cases.

The driving roller unit 110 is disposed farther away from the edge surface 210 of the panel 200 than the coating roller unit 120 described below. This is because the main drawing portion 130 connecting the driving roller portion 110 and the coating roller portion 120 by rotating the driving roller portion 110 and the coating roller portion 120 is disposed on the edge surface of the panel 200 Since the display panel 210 is inclined with respect to the edge 210 of the panel 200, only one side of the panel 200 is intensively contacted with the edge 210, thereby maximizing the coating effect.

The coating roller unit 120 is disposed so as to be spaced apart from the driving roller unit 110. The coating roller unit 120 is rotated by the main drawing unit 130 to be described below and is rotated in the same direction as the driving roller unit 110.

The coating roller unit 120 has a cylindrical shape like the driving roller unit 110, and is made of metal or plastic. The coating roller unit 120 is rotatable in the forward or reverse direction together with the driving roller unit 110. As shown in the drawing, the coating roller unit 120 has the same diameter as that of the driving roller unit 110, and may have diameters different from each other in some cases.

The main drawing part 130 rotates the drive roller part 110 and the coating roller part 120 and rotates in one direction with a rotational force generated in the conventional driving motor to paint one surface of the panel 200 as an object .

The main drawing part 130 is made up of fibers such as a mother and a cotton having excellent absorbing ability on one side and easily absorbs the supplied paint and the other part is composed of a timing belt or a chain so that the driving roller part 110 and the coating roller part 120 Respectively. The main drawing part 130 made of fiber on one side can be easily coated when the edge face 210 of the panel 200 to be coated is rounded or inclined. The main drawing part 130 is connected to the driving roller part 110 and the coating roller part 120, which are arranged in a stepped manner, and is inclined with respect to the panel 200. The inclined main ledge 130 is brought into contact with the edge surface 210 of the panel 200 to be painted on one side. Specifically, when the edge of the panel 200 connected to the paint roller 120, So that it comes into contact with the surface 210. This is because when the entire main drawing part 130 touches the edge surface 210 of the panel 200, a part of the main drawing part 130 is sagged and the painting effect on the edge surface 210 of the panel 200 It is possible to maximize the coating effect by concentrating only one surface.

The main drawing part 130 of the present invention is illustrated as being coated when the edge face 210 of the panel 200 as the object to be coated is rounded or inclined. However, when the edge face 210 of the panel 200 is recessed Even if it is a groove, painting can be possible.

The painting material supplying unit 140 is installed on one side of the main painting unit 130 to supply the painting material. The paint supply unit 140 is disposed on the right side of the first contact roller unit 150 to be described below and is driven by the drive roller unit 110 or the main handle 130 and the first contact roller unit 150, (150). Thus, the paint is easily sucked into the main drawer 130 surrounding the outer peripheral surface of the drive roller portion 110.

The coating material supplied between the driving roller unit 110 or the main roller 130 and the first contact roller unit 150 may be a variety of conventional paints, ultraviolet coatings (UV coatings), and urethane coatings.

The end portion of the coating material supplying unit 140 facing the driving roller unit 110 or the main coating unit 130 is formed in a nozzle shape to continuously supply a predetermined amount of coating material to the main coating unit 130.

The paint supplied to the main draw part 130 is preferably made of liquid or powder and is always kept in a constant state irrespective of season or temperature such as spring, summer and the like.

The first contact roller unit 150 is spaced apart from the driving roller unit 110 and is spaced apart from the driving roller unit 110 so as to supply paint for painting one surface of the panel 200 as an object. The first contact roller unit 150 has a cylindrical shape like the driving roller unit 110, and the diameter of the first contact roller unit 150 is smaller than the diameter of the driving roller unit 110. The first contact roller unit 150 prevents the main roller unit 130 from being separated from the driving roller unit 110 when the main roller unit 130 is rotated.

The first contact roller unit 150 is disposed below the drive roller unit 110 surrounded by the main roller 130 and is adjustable in distance from the drive roller unit 110. This is for controlling the thickness of the paint applied to the edge surface 210 of the panel 200 by adjusting the amount of the paint as shown in FIG. The first contact roller unit 150 adjusts the amount of the paint supplied through the distance adjustment to adjust the thickness of the paint coated on the edge surface 210 of the panel 200 in the forward direction, When the rotation is in the reverse direction, the first adhesion roller unit 150 may serve to remove the coating material remaining in the main roller 130.

The first contact roller unit 150 is disposed stepwise with respect to the second contact roller unit 160 to be described below, such that the drive roller unit 110 is disposed stepwise with the coating roller unit 120.

The second adhesion roller unit 160 is spaced apart from the coating roller unit 120 to remove the coating material remaining in the main coating unit 130. The second contact roller unit 160 has a cylindrical shape and has the same diameter as the first contact roller unit 150.

The second contact roller unit 160 prevents the main roller unit 130 from being detached from the coating roller unit 120 when the main roller unit 130 rotates, like the first contact roller unit 150.

The second contact roller unit 160 is disposed below the coating roller unit 120 surrounded by the main roller 130 and is adjustable in distance from the coating roller unit 120. This is to control the removal amount of the paint remaining in the main drawing part 130 in the forward direction.

4, the second contact roller unit 160 may be rotated in the opposite direction to the second contact roller unit 160 when the rotation of the main roller unit 130 is in the reverse direction, May control the thickness of the paint applied to the edge surface 210 of the panel 200 by adjusting the amount of the paint supplied through the distance adjustment.

5, the auxiliary drawing part 170 is disposed adjacent to the main drawing part 130 connected to the painting roller part 120 and is fixedly arranged to paint one surface of the panel 200 as an object . One side of the auxiliary drawing part 170 that touches the edge surface 210 of the panel 200, such as the main drawing part 130, is made of fibers such as a mother and a cotton having excellent absorbing ability to easily absorb the paint.

The auxiliary drawing part 170 can paint the edge surface 210 of the panel 200 using at least one of the main drawing part 130 and the auxiliary drawing part 170. [ This is because the edge surface 210 of the panel 200 can be coated through the auxiliary screen 170 when the paint of the paint supply unit 140 is exhausted to the main screen 130, The edge surface 210 of the panel 200 may be coated only through the main drawing part 130 when the paint supplied to the panel 200 is used up. The auxiliary drawing part 170 of the present invention is exemplified by selecting any one of the main drawing parts 130 to paint the edge surface 210 of the panel 200. However, 200 can be painted double. As a result, the edge surface 210 of the panel 200 is painted more evenly, so that a high-quality panel can be obtained by improving the cohesion with the upper and lower surfaces.

The secondary ledge 170 may be painted even if the edge surface 210 of the panel 200 is rounded or inclined or is a recessed groove.

6 is a flow chart of one embodiment of a painting method for a panel according to the present invention. The painting method (S100) for a panel according to an embodiment of the present invention includes a lower portion (S110), a middle portion (S120), and a upper portion (S130).

First, the lowering step S110 is carried out in the primary polishing step S111, the primary coating step S112, and the primary drying step S113. In the primary polishing step S111, the edge surface 210 of the irregular panel 200 is polished using sandpaper, and the edge surface 210 of the panel 200, which has undergone the primary polishing step S111, The surface becomes even.

Preferably, the sandpaper has a grain size of about 150 to 220, and the edge surface 210 of the panel 200 is polished several times by using sandpaper having a large grain size as needed. The size of the sandpaper shows the degree of roughness of the surface of the sandpaper according to the particle size (degree of thickness) of the abrasive. The rougher the surface, the smaller the number displayed. Sandpaper is an abrasive used to polish the surface of a workpiece by attaching various grades of aluminum oxide such as paper or cloth to the surface. It is also called sandpaper.

The primary coating step S112 is a step of coating the paint through the painting apparatus 100 for a panel as described above, and the primary coating step S111 is performed on the edge surface 210 of the panel 200, Lt; / RTI >

The primary coating step S112 is to paint the edge surface 210 of the panel 200 through the painting apparatus 100 for a panel using a paint made of paint, ultraviolet paint (UV paint), urethane paint, As a result, a coating film is formed on the edge surface 210 of the panel 200.

The coating material applied through the panel coating apparatus 100 is a coating material that is cured in a relatively short time due to the chemical action of ultraviolet rays, and is characterized by low pollution, minimization of energy consumption, and high productivity.

In the primary drying step S113, UV light (Ultra Violet Lamp) is applied to the edge surface 210 of the panel 200 through the primary coating step S112 to dry the painted coating.

In the primary drying step S113, the UV light is applied to the edge surface 210 of the panel 200 painted with the UV (Ultra Violet) lamp to paint the edge surface 210 of the panel 200 The coating material is dried to form a coating film. In this case, the primary drying step (S113) preferably irradiates the UV light onto the edge surface 210 of the panel 200 to which the coating material is applied for 4 to 5 seconds.

As described above, the edge surface 210 of the panel 200 having undergone the lowering step S110 is subjected to the secondary polishing step S121, the secondary coating step S122, and the secondary drying step S123, .

The secondary polishing step S121 is performed by using sandpaper relatively finer than the sandpaper of the primary polishing step S111 to clean the coating surface of the edge surface 210 of the dried panel 200. [ In the secondary polishing step (S121), polishing is performed twice using sandpaper having a different particle size. The secondary polishing step S121 is preferably a sandpaper having a grain size of about 320 to 400. This is because the surface of the edge surface 210 of the panel 200 painted with the paint is finely polished, To improve adhesion and adhesion.

In the second coating step S122, a coating film is formed on the first side and the paint is applied again to the edge surface 210 of the polished panel 200 through the coating device 100 for a panel. In this case, the coating film formed through the primary coating step S112 may be a transparent coating film formed by spraying a transparent coating material, or may be a predetermined color coating film formed by spraying a predetermined coloring material. In particular, And may be a coating film formed to have an image.

The reason why the constituents of the paint used in the first coating step S112 and the second coating step S122 are different is that the paint is first coated on the edge face 210 of the panel 200, If the second coating is applied before full curing, the first coating does not cure completely and the adhesion of the second coating to the first coating increases.

In the second drying step S123, UV light is applied to the coating material painted on the edge surface 210 of the panel 200 to dry the secondary coating material, so that the surface treatment of the edge surface 210 of the panel 200 .

As described above, the edge surface 210 of the panel 200 having undergone the intermediate step S120 is subjected to the tertiary painting step S131 which is the topsheet S130. The edge surface 210 of the panel 200 having undergone the step S110, the intermediate step S120 and the top surface S130 forms a coating film having an image through the tertiary painting step S131 of the topsheet S130, The color can be more clearly expressed, can be clearly expressed, and further, the effect of improving the three-dimensional effect is obtained.

The surface of the edge surface 210 of the panel 200 is coated with the surface S120, the intermediate surface S120 and the top surface S130 to improve the appearance and the durability, The painting is processed by an automated process through a mechanized device and painted in large quantities. The coating method for a panel S100 of the present invention can work in the reverse direction of the lower surface S110 and middle direction S120 and the reverse direction of the upper surface S130 according to the painting of the edge surface 210 of the panel 200 .

One embodiment of the present invention described above and shown in the drawings should not be construed as limiting the technical idea of the present invention. The scope of protection of the present invention is limited only by the matters described in the claims, and those skilled in the art will be able to modify the technical idea of the present invention in various forms.
