Description

[0001] Embossing device for pressing plate [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an apparatus for processing a decorative pattern on wood, and more particularly to an embossing apparatus for pressing a plate material formed by pressing an emboss pattern directly on a surface of a plate material.

Generally, furniture such as cabinets and cabinets are formed by various engraving patterns on the front side and engraved on the surface of the furniture by engraving or embossing directly or by attaching a decorative plate engraved with embossed and embossed patterns .

Most conventional decorative panels include PVC sheet with PVC sheet and paper sheet panel decorated with paper. PVC plywood is made of Medium Density Fiberboard (MDF), Particle Board (PB) Plywood and gypsum board by coating a PVC sheet on the surface of the substrate layer.

This decorative plate has a severe thermal deformation due to temperature change, so that the film is hardened during the winter operation and the impact resistance is lowered, resulting in poor product and production efficiency. In addition, there is a fatal problem to the human body because it releases a large amount of toxic gas during incineration or fire . On the other hand, the paper sheet panel adheres a paper sheet printed on the surface of the base material, which causes problems such as generation of bubbles and peeling in the bonding process, which leads to deterioration of product quality.

In addition, in the case of the decorative plate to be applied to the furniture requiring the decorative effect, it is not only difficult to process the plate, but it is expensive because it is difficult to mass-produce it, And the like.

In recent years, there has been an increasing tendency to decorate furniture with a method of directly attaching natural veneer to furniture. In the case of such a natural wood veneer panel, the veneer must be separately formed and attached to the surface of the plate material. But, over time, there will be defects that can easily be separated from the plate or furniture.

SUMMARY OF THE INVENTION The present invention has been made to solve the problems of the conventional art described above, and it is an object of the present invention to provide a decorative sheet for a decorative sheet, And an embossing device for pressing the plate material.

Another object of the present invention is to prevent the occurrence of fire in the manufacture of products by effectively radiating and cooling the high heat generated while radiating high heat from the outside of the plate during the pressing processing of the plate, And an embossing device for pressing a sheet material.

It is still another object of the present invention to provide an embossing apparatus for pressing a sheet material to automate all steps of a sheet material processing operation so as to realize a precise and simple process.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 4 illustrate an embodiment of the present invention. An embodiment of the present invention includes an apparatus main body 10, an upper roller assembly 20 installed substantially at the center of the apparatus main body 10, And a lower roller assembly 30 installed in correspondence with the upper roller assembly 20 to support the plate 1 passing through the upper roller assembly 20 and a lower roller assembly 30 installed outside the roller assemblies 20, (50) for transmitting high heat to the outer surfaces of the upper and lower roller assemblies (20, 30), a cooling system unit (50) for cooling the high heat generated in the heating devices (40, 50) And a controller 70 for controlling operations of the roller assemblies 20 and 30, the heating devices 40 and 50, and the cooling system unit 60.

The apparatus main body 10 is formed in the form of a housing having a large rectangular shape as shown in Fig. The housing is formed by a base (12) and a body (14) formed integrally with the base (12).

The roller assembly according to the present invention comprises an upper roller assembly 20 and a lower roller assembly 30. The upper roller assembly 20 includes an upper roller 22, 22, and a driving motor 26 connected to one end of the rotating shaft to drive the rotating shaft 24. The rotating shaft 24 is rotatably supported by the rotating shaft 24,

The lower roller assembly 30 includes a lower roller 32, a rotating shaft 34 provided at the center of the lower roller 32, and a driving motor 36 for driving the rotating shaft 34.

3, the heating devices 40 and 50 include an upper heating device 40 installed at a position corresponding to the upper roller assembly 20 and a lower heating device 40 corresponding to the lower roller assembly 20, And a lower heating device 50 installed at the position. The upper heating device 40 includes an upper burner part 42 as a heat source, an upper burner 44 for transmitting heat generated from the upper burner part 42 to the roller side, And a burner adjuster 46 for adjusting the up and down direction and the angle at which the heat is irradiated. The lower heating device 50 includes a lower burner part 52 as a heat source, an upper burner 54 for transmitting heat generated from the lower burner part 52 to the roller side, And a burner adjuster 56 for adjusting the vertical direction and the angle at which the heat is irradiated.

The heating devices (40) and (50) are detachably mounted to the apparatus main body (10). That is, the upper heating device 40 and the lower heating device 50 can be separated from the device body 10 at the time of replacement for maintenance because each heating device is installed as a heater block, which is a unit assembly.

The cooling system unit 60 is constituted by a water-cooled system including an upper water tank 62 and a lower water tank 64 as shown in FIG. An upper water pipe 66 and an upper water pipe 67 are connected to the upper water tank 62 and a lower water pipe 68 and a lower water pipe 69 are connected to the lower water tank 64, respectively. However, it is needless to say that the cooling system unit 60 is not limited to a water-cooled type and can be used together with an air-cooled cooling system.

1, the controller 70 is installed at one side of the apparatus body 10 and includes the upper roller assembly 20, the lower roller assembly 30, the upper heating device 40, (50) and the cooling system unit (60) so that the operator performs the control operation. The controller 70 may be connected to one side of the apparatus body 10 and may be remotely controlled using a remote controller in a separate space.

The operation of the embossing apparatus according to the present invention will now be described with reference to FIG.

First, the operator performs a step of inputting power by turning on the power (Power Input Step).

In order to perform a general embossing process in the control unit 70, an operation for each step is initialized (Installation Step). It is not necessary to perform this initialization step every time, but it can be performed periodically or selectively in accordance with the emboss pattern printed on the plate as the movable object.

Next, a first heating step of heating the surfaces of the upper roller 22 and the lower roller 32 on which the mold is mounted is performed (Installation and Heating of Rolls Step). For the upper roller 22, the corresponding upper heating device 40 is actuated to heat up the heat. In addition, the lower roller 32 is operated by the lower heating device 50 provided corresponding thereto to be irradiated with heat. Since the upper and lower heating devices 40 and 50 have the same configuration, the upper heating device 40 sets the position of the upper roller 22 when the upper roller 22 is heated.

5, the high heat generated in the upper burner portion 42 of the upper heating device 40 is irradiated to the surface of the embossing mold E1 mounted on the upper roller 22 through the upper burner 44 do. At this time, the burner regulator 46 is adjusted so that the best end of the upper burner 44 is set to a position parallel to the tangent of the upper roller 22. [ That is, the angle is adjusted while rotating the upper burner 44 by a mechanism interlocked with the rotation of the burner regulator 46. [ Such a mechanism includes movement in the horizontal direction or movement in the vertical direction. 5 shows a state in which the upper burner 44 is rotated about the axis of rotation 48 and is set at an optimum angle of the upper burner 44. [ When the surface of the embossing mold E1 is heated outside the upper roller 22, the surface of the embossing mold E1 is also raised at a predetermined molding temperature in the earliest time.

The upper roller 22 and the lower roller 32 are disposed in a working position to perform an actual embossing operation. [0030] Fitting of Rolls Step [0035] Normally, the upper roller 22 is moved downward to be in contact with the upper surface of the plate 1 . The lower roller 32 supports the lower surface of the plate 1 as it is at the position where the lower roller 32 is disposed.

The sheet material 1 fed in a state where the upper roller 22 is lowered and moved to the working position passes between the embossing die mounted on the upper roller 22 and the mounted die of the lower roller 32. At this time, the emboss pattern engraved in the embossing mold E1 mounted on the upper roller 22 is embossed on the upper surface of the sheet material 1 (Wood Embossing Step). Embossed patterns can be provided in various shapes and shapes by embossing patterns formed on the embossing molds. The processing of embossing patterns can realize various decorative patterns irrespective of the type and quality of the sheet material 1. At this time, when the emboss pattern is processed at both sides of the sheet material 1 at the same time, the emboss pattern engraved on the lower embossing die on which the lower roller 32 is mounted is embossed on the lower surface of the sheet material 1.

Since the embossing mold E1 mounted on the upper roller 22 is heated by the upper heating device 40, the plate material 1 is softened with a high heat so that the pressing operation is smoothly performed. It is preferable that the embossing mold mounted on the lower roller 32 is also heated by the lower heating device 50. [ As described above, both surfaces of the plate material 1 passing through the upper and lower rollers 22 and 32 are heated at the same time, thereby preventing the plate material 1 from being deflected to one side.

The second heating operation can be performed at the time when the surface temperature of the embossing die mounted on the upper roller 22 or the lower roller 32 drops while the embossing operation is performed for a predetermined time. This is because the embossing operation is temporarily stopped by inputting the processing amount of the work in advance into the control unit 70 and the upper roller 22 is raised to a certain height so that the surface of the upper side mold is heated by the upper heating device 40, The surface of the lower mold is heated by the lower heating device 50 of the roller 22.

Alternatively, if an additional operation is not required, a cooling system unit loading step for cooling the heated upper roller 22 or the lower roller 32 is performed.

The control step for controlling the heating step and the operation step (control step) can be selectively performed by the operator by operating the control unit 70 in consideration of the material of the plate material, the shape of the emboss pattern, the working speed,

When the emboss pattern pressing work for the plate material is completed, the worker turns off the power.

A thermal sensor (not shown) that senses the occurrence of an abnormality of the apparatus due to the residual heat even when the power is turned off after completing the processing of the emboss pattern is operated by a separate power source. Accordingly, when the heat sensor senses the residual heat, the controller 70 automatically activates the cooling system unit 60 to automatically prevent the occurrence of errors and fire due to overheating.

The embossing apparatus for pressing the sheet material according to the present invention uses an embossing die mounted on the upper and lower rollers, respectively. These embossed dies are mounted on the upper roller or the lower roller, respectively, depending on the shape and shape of the decorative pattern, and the work of removing the dies from the rollers and replacing the new dies is performed from time to time. In this case, since the mold is the weight of the tonnage, it is difficult to replace the worker with the manpower, so the ordinary forklift is used.

In the present invention, the structure of the transfer device 80 as shown in FIG. 2 may be further provided for mounting and replacing the mold. The conveying device 80 includes a support 82, a roller 84 that is rotatably mounted on the support 82, a speed reducer 88 that decelerates and transmits the power of the motor 86 and the motor .

When the mold is inserted and discharged by the transfer device 80 having such a configuration, the transfer belt assembly 90 is connected to one side of the apparatus main body 10 as shown in Fig. Therefore, the mold can be inserted into the transfer device 80 after the mold is seated through the transfer block assembly 90, or the mold placed in the transfer device 80 can be discharged to the transfer block assembly 90 side.

The mold used in the present invention may have a considerable weight and the temperature may be elevated due to high temperature. Thus, by using the transfer device 80 and the transfer platform assembly 90 as described above, the efficiency of the operation can be maximized. The upper and lower roller assemblies 20 and 30 can also be replaced by using the transfer device 80.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is clearly understood that the same is by way of illustration and example only and is not to be construed as limiting the scope of the invention as defined by the appended claims. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the present invention.
