Description

Method for processing asymmetric or curved floor}

The present invention relates to an asymmetrical or curved floor processing method, and more specifically, it can be processed in a variety of forms according to the intention of the manufacturer, as well as a regular shape, such as a rectangular like a general floor currently produced, and also in the processing method It is possible to grooving the entire side while simultaneously cutting and tenon processing while moving the processing machine for the fixed product without moving the product by dividing the cutting or tenon. A method of processing asymmetric or curved floors freely.

In general, floors made of wood are used a lot of materials, and eco-friendly floorings are being introduced for the purpose of blocking moisture on concrete floors and blocking harmful substances with the development of houses, especially apartment culture.

The most common floor is a soft PVC sheet because of its excellent processability and flexibility.

However, the necessity of development of environmentally friendly materials has emerged as human hazards are highlighted by various additive materials added for processing PVC, such as plasticizers, viscosity reducing agents, and organic solvents.

In particular, in the case of flooring material having a certain thickness and abrasion resistance is required, only the simple PVC could not satisfy the required characteristics.

For example, the most common floor, the current floor, was developed by collecting only the merits of plywood floor, which is to laminate the HPL (High Pressure Laminate) on the plywood (plywood) to give a feeling close to the natural floor.

That is, as shown in the example of Figure 1, the floor is a pattern of laminated veneer / solid wood on the plywood / solid wood, HPL laminated on the plywood / High Density Fiber Board (HDF) / Medium Density Fiberboard (MDF), LPM (Low Pressure) HDF / MDF laminated on Melamine and LPM laminated on top of it, PVC / PP / PET sheet laminated on Plywood / HDF / MDF / WPC (Wood Polymer Composite) / SPC (Stone plastic composite) It is becoming.

However, such a floor is manufactured in a rectangular shape and then the tongue and the click are processed for mutual coupling.

Therefore, in order to process such a product, the tongue and the click must be processed through a separate process after being cut.

In particular, the blade to be processed, that is, the processing machine has a limitation that can only be processed in inevitable rectangular shape because it is a form that is processed while moving the semi-finished product to be processed in a fixed state.

In addition, conventional assembly of floors is a way to fit the tongue and the click, because only rectangular processing is inevitable had a limitation that can be constructed only in one direction.

Republic of Korea Patent No. 10-0537541 (December 12, 2005) 'floor flooring having veneer and synthetic resin layer using a symmetrical structure and its manufacturing method'

The present invention was created in view of the above-mentioned problems in the prior art as described above, and can be processed in various forms according to the intention of the manufacturer, not in a constant form such as a rectangle like a general floor currently being produced. In the processing method, grooving the whole side while moving the product to perform cutting and tenon processing at the same time as the processing machine moves on the fixed product without separating the cutting or tenon. Its main purpose is to provide an asymmetrical or curved floor processing method which can free the construction direction.

It provides asymmetrical or curved floor processing method comprising a; grooving processing step (S130) to form only grooves using all the circumference of the tenon processed and cut semi-finished products.

In this case, the semi-finished product is also characterized in that it is manufactured in the form of plywood by pressing or hot pressing after applying the adhesive to the interface forming the layer structure.

In addition, the semi-finished product is in the form of laminated veneer / wood on plywood / solid wood, HPL laminated on plywood / High Density Fiber Board (HDF) / Medium Density Fiberboard (HDF), HDF / MDF on Low Pressure Melamine (LPM) It is also one of the forms of lamination and LPM laminated on top of it, PVC / PP / PET sheet laminated on plywood / HDF / MDF / WPC (Wood Polymer Composite) / SPC (Stone plastic composite). There is this.

According to the present invention, not only a regular floor like the current floor is produced, but also can be processed in various forms according to the intention of the manufacturer, not only a rectangular shape, but also in the cutting method by moving the product to separate the cutting or tenon (Tenoning) It is possible to groove the whole side while cutting machine and tenon processing can be performed simultaneously while the processing machine for the product which is fixed without processing can get the effect of freeing the direction of construction.

Hereinafter, with reference to the accompanying drawings will be described in detail a preferred embodiment according to the present invention.

Prior to the description of the present invention, the following specific structures or functional descriptions are merely illustrated for the purpose of describing embodiments according to the inventive concept, and the embodiments according to the inventive concept may be implemented in various forms, It should not be construed as limited to the embodiments described herein.

In addition, embodiments in accordance with the concepts of the present invention may be modified in various ways and may have various forms, specific embodiments will be illustrated in the drawings and described in detail herein. However, this is not intended to limit the embodiments in accordance with the concept of the present invention to a particular disclosed form, it should be understood to include all modifications, equivalents, and substitutes included in the spirit and scope of the present invention.

Asymmetrical or curved floor processing method according to the present invention can differentiate the flooring design by allowing the user to process the shape of the floor in a variety of forms, in particular asymmetrical, curved, etc. using a CNC (Computerized Numerical Control) equipment In addition, cutting and tenone processing can be performed at the same time to achieve work efficiency.

More specifically, the asymmetric or curved floor processing method according to the present invention includes a semi-finished product manufacturing step (S100), as shown in FIG.

The semi-finished product manufacturing step (S100) is a step of making a workpiece plate having a plurality of layer structures as illustrated in FIG.

In this case, the reason why the semi-finished product is called is because the plate is not cut and tenon processed, and after cutting and tenon will be referred to as a product.

In addition, the semi-finished product is manufactured in the form of plywood by applying an adhesive to the interface forming the layer structure and then pressing or hot pressing.

In other words, the floorboard material is not cut, tenon, grooving, which can be understood as a semi-finished product.

Then, CAD and CNC setting step (S110) is performed.

The CAD and CNC setting step (S110) is a step of setting the program to document the floor shape to be processed into a CAD, and CNC machining based on the documented CAD information.

At this time, setting the program to CNC process the CAD information means a known concept to read the coordinate information implemented in the CAD to be automatically numerically processed through the CNC.

In other words, the shelf computer reads the coordinate information numerically and sets it so that the cutting can be performed while moving the tenon (cog saw) according to the coordinate information.

Thereafter, the tenon processing step S120 is performed.

The tenon processing step (S120) is not a rectangular processing as conventional, so the cutting is done at the same time the tenon processing using a CNC.

In other words, in the prior art, the cutting work and the tenon processing work had to be separated and performed independently, but in the present invention, the asymmetric processing or the curvature processing should be performed, so that the tenon processing becomes a simultaneous concept including cutting up.

Such a tenon processing example can exemplify asymmetric processing as well as curved processing as in the exemplary photograph of FIG. 3.

In addition, when there is a pattern as shown in Figure 4 can be made according to the pattern through the unique tenon processing to create a floor having a different design according to the tenon direction or shape of the pattern repeatedly repeated.

Finally, grooving processing step S130 is performed.

The grooving step (S130) had to form a tongue on one long side of the semi-finished product and a groove on the other long side in order to have a conventional fitting structure. In other words, one semi-finished product had to be processed with different widthwise sides, so the work was cumbersome and difficult, especially while moving the semi-finished product while the equipment was fixed.

As a result, the skill of the operator acts as a very important quality factor, resulting in a qualitative difference in the quality of the product according to the skill.

However, in the present invention, by using a router (Router), only a groove is formed without forming a tongue is configured so that a product of a certain quality is always made regardless of the skill of the operator.

That is, the grooving processing step S130 is a processing step of forming only grooves around all of the semi-finished products.

At this time, the luther is composed of a vertical spindle, column, and a table that can be moved up and down with a high speed rotation, and mainly can guide, center, or guide the center pin to be engraved, chamfered, or cut. As a machine, the bit blade 100 illustrated in Fig. 5 can be used to groove the entire side of the semifinished product into a groove of a certain shape.

Therefore, there is no need to turn the semi-finished product or turn the position as before, and the semi-finished product can be made with a unique design because the semi-finished product is processed while the equipment moves while being fixed.

Here, the floor according to the present invention can not be a fitting assembly of the tongue-click as conventional, because only the groove is formed around the side.

Therefore, the floor according to the present invention may be assembled using a separate subsidiary material, such as a groove or a wood which can connect the groove.

As described above, the processing method according to the present invention has a distinctive distinction from the existing prior art in that it is possible to implement a floor having a unique and diverse design, in particular, a floor designed by only one in the world. Can be.

In addition, the processing method according to the present invention does not need to completely exclude a method of forming a tongue on one long side of the floor and a groove on the other long side. In other words, the above-described processing method is the most basic concept, and if necessary, both sides of the floor may be configured differently. In the processing, the equipment is moved and processed so that it is easily processed to have various designs such as curves and asymmetries. It is a big difference from the existing in that it can be done.
