MDF (medium density fiber) board is a type of processed material made of wood by pressing and molding wood fibers obtained by using wood materials as a raw material with an adhesive at high temperature and high pressure.

These MDFs include high density fiberboards (HDF), medium density fiberboards (MDF), and low density fiberboards (LDF) depending on the size of the medium density and mainly produce 3 to 30 mm thick.

These medium-density fiberboards are widely used as materials for furniture, etc., instead of ordinary wood because of their dense and uniform texture and excellent machinability and strength. It is often used by bonding.

On the other hand, particle board (particle board) is a processing material made by producing wood from solid wood, crushing the remaining waste residue into small pieces, mixing the adhesive and pressing it at high temperature and high pressure.

These particle boards can compensate for the shortcomings of the wood, absorb sound well, vary the size and shape, and are efficient and economical in terms of recycling the waste residue generated during the processing of various wood. .

Among them, a number of holes or rough surfaces on the side or both sides of the particle board, which is a wood panel, are used with a finishing sheet such as veneer or polyester resin to refine the appearance and prevent deformation of the wood panel due to moisture.

However, due to the nature of the wood panel, there are a myriad of holes and rough surfaces on the cut side, so when the cut surface is processed and then attached to the veneer or finish sheet, the adhesion strength of the attachment surface is weak due to the myriad of holes and rough surfaces. It is easily peeled off and is particularly vulnerable to moisture, and it is difficult to expect a beautiful appearance even after re-processing, and there is a problem in that it requires two to three re-workings to increase cost.

In addition, if a curable adhesive is used for coating the surface of the processed wood or attaching a decorative sheet to the surface, excellent adhesion performance can be secured, but when a curable adhesive is used for the material of the particle board, irregularities may occur at the end of the surface. There was a problem that the inexpensive particle board could not be used for the purpose of coating the surface of the processed wood or attaching a decorative sheet to the surface.

On the other hand, the wooden material for furniture is usually a finishing material, the film is coated with a film on the surface, and as a processed wood, a printed finishing material having a printed layer formed on a film sheet made of a resin such as polyvinyl-based resin that can exhibit a unique pattern such as wood. It will be equipped.

However, due to the nature of the wood panel, there are a myriad of holes and rough surfaces on the cut side, so when the cut surface is processed and then attached to the veneer or finish sheet, the adhesion strength of the attachment surface is weak due to the myriad of holes and rough surfaces. It is easily peeled off and is particularly vulnerable to moisture, and it is difficult to expect a beautiful appearance even after re-processing, and there is a problem in that it requires two to three re-workings to increase cost.

In addition, if a curable adhesive is used to coat the surface of a processed wood, such as a medium-density fiberboard (MDF), or to attach a decorative sheet to the surface, excellent adhesive performance can be secured, but if a curable adhesive is used in its material, processing is performed. There is a problem in that it is difficult to be used for the purpose of coating the surface of the processed wood or attaching a decorative sheet to the surface because it causes irregularities at the surface end of the wood.

Accordingly, it is urgent to develop a method for easily fabricating an edge structure that can prevent the penetration of moisture through the edge portion of the panel for furniture production.

It shows the edge cross-sectional shape of the completed sheet paper 50.

It can be appreciated that the present invention can be implemented through the following steps as shown.

First, the release agent 30 is applied along the upper and lower edges of the panel 10 (S1: first step).

Then, the adhesive PUR is applied to the edge surface 20 that is vertically adjacent to the upper and lower surfaces of the panel 10, and the adhesive is applied so that the upper and lower surfaces perpendicular to the edge surface 20 are exposed (S2: second step).

In addition, a protective agent 70 is applied to prevent the foreign substances from adhering to the adhesive along the edges of the upper and lower surfaces of the panel 10 and the adhesive exposed on the upper and lower surfaces of the panel 10 perpendicular to the edge surface 20 of the panel 10 ( S3: Third step).

Then, the trimming is performed to remove the excess adhesive portion exposed on the upper and lower surfaces of the panel 10 beyond the thickness of the edge surface 20 (S4: fourth step).

Further, in order to remove the foreign matter generated in the fourth step (S4) from the panel 10, the cleaning agent 90 is applied to the edge surface 20 and the upper and lower surfaces of the panel 10 (S5: 5th step).

In addition, in order to polish the cured PUR on the edge portion of the panel 10, the disk 100 of the fiber material is introduced up and down to polish the panel 10 (S6: sixth step).

Here, the panel 10 may be a particle board or a medium density fiber board.

The present invention can be applied to the above-described embodiments, it is of course also possible to apply the following various embodiments.

In the method of adhering the edge of the panel according to the present invention, the cut panel 10 is put on a conveyor belt (not shown below) of the edge bending device by cutting the panel with the upper and lower surfaces adhered to the coating sheet according to dimensions.

Simultaneously with the input, the step of applying a release agent along the upper and lower edges of the cut panel proceeds (S1).

Referring to FIG. 2 (a), the release agent 30 is applied along the edges to the upper surface 12 and the lower surface 15 of the panel 10 to facilitate removal of the cured adhesive PUR in a later process.

The release agent 30 is a releasing agent containing an ethyl alcohol component, and when a curable adhesive PUR (Polyurethane Reactive Resin), which is an adhesive, is applied to the edge surface 20, the edge surface is exposed up and down and the extra PUR is exposed to the panel ( It adheres to the upper and lower surfaces (12, 15) of 10) and is cured, but a release agent is applied in advance to remove it later.

Next, the adhesive PUR is applied to the edge surface 20 vertically adjacent to the upper and lower surfaces 12 and 15 of the panel, and the adhesive is applied so that the upper and lower surfaces perpendicular to the edge surface are exposed (S2).

Referring to FIG. 2 (b), the application of the adhesive PUR to the edge surface 20 of the panel is applied to the bond roller while the bond roller 40 applied to the surface of the PUR rotates and contacts the edge surface of the transferred panel. It is made by applying the applied PUR to the edge surface.

In addition, the sheet paper 50 is adhered to the adhesive PUR applied to the edge surface 20, and the sheet is bonded to the edge surface by curing the PUR while pressing and pressing with a pressing roller 60.

In addition, the PUR application amount should be applied such that the adhesive PUR is exposed on the upper and lower surfaces 12 and 15 of the panel 10 perpendicular to the edge surface 20.

The reason why the adhesive PUR applied to the edge surface is exposed up and down the panel is between the upper and lower surfaces and the edge surface of the panel so that the edges forming the boundary between the upper and lower surfaces 12 and 15 of the panel and the edge surface 20 are covered by the PUR. It is to prevent moisture from penetrating through the cut surface and the edge of the panel 10 by allowing it to be set and hardened without gaps.

Generally, when the panel is a particle board, the porosity is larger than that of the MDF, so the PUR coating amount should also be set to a value greater than the MDF.

Next, a step of applying a protective agent (70, protective agent) along the top and bottom edges of the panel and the adhesive exposed on the upper and lower surfaces of the panel perpendicular to the edge surface of the panel proceeds (S3).

Referring to Figure 2 (c), the upper surface 12 and the lower surface 15 of the panel 10 is coated with a protective agent 70 along the edges to facilitate removal of the adhesive PUR cured in a fourth step (S4). To do.

The reason for applying the protective agent 70 to the upper and lower surfaces 12 and 15 of the panel 10 is when the excess amount of the adhesive PUR applied to the edge surface 20 is exposed on the upper and lower panels to adhere to the upper and lower surfaces, the PUR adhesive In order to prevent the trimming is difficult in the fourth step (S4), since various foreign matters adhere to the.

In particular, the reason for applying the protective agent is to prevent the edge powders generated during the trimming operation from sticking to the PUR exposed on the upper and lower surfaces 12 and 15 of the panel 10.

That is, the adhesive exposed on the upper and lower surfaces 12 and 15 of the panel 10 and the protective agent of the ethyl alcohol component are applied along the upper and lower edges of the panel.

Next, a trimming step is performed to remove the excess adhesive portion exposed on the upper and lower surfaces 12 and 15 of the panel 10 beyond the thickness of the edge surface (S4).

Referring to FIG. 3 (a), the trimming process trims the excess PUR portions and sheet paper portions exposed on the upper and lower surfaces 12 and 15 of the panel 10 to match the thickness of the panel 10.

The trimming fixation removes the excess PUR portion and sheet paper portion exposed using the trimmer 80 on the upper and lower surfaces 12 and 15 of the panel 10.

Referring to FIG. 3 (b), after the fourth step (S4), a trimming step is performed by applying a cleaning agent 90 containing an ethyl alcohol component to the edge surface 20 and the upper and lower surfaces 12, 15 of the panel 10 In order to remove foreign substances such as dust generated from the panel from the panel (S5).

Six steps of the panel 10 by repeatedly performing the fifth step S5 in the first step S1 above on four edge surfaces 20 perpendicular to the upper and lower surfaces 12 and 15 of the panel 10. All of this is made to complete the adhesion to the sheet paper 50 by PUR.

Finally, the edge bonding process of the panel is finished by performing a step of polishing with a fiber disc (textile disc 100) (S6).

Referring to Figure 3 (c), both the front and rear left and right edge surface 20 is finished with a sheet paper 50 cured by PUR, and finally the cured PUR part at the corner of the panel is gentle enough to sharpen In order to grind in the state, the disc 10 of the fiber material is introduced up and down simultaneously at the top and bottom of the panel 10 to perform a polishing operation.
