Description

TECHNICAL FIELD [0001] The present invention relates to a vacuum insulation board, a manufacturing apparatus and a manufacturing method thereof,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vacuum insulating plate, and more particularly, to a heat insulating plate having a heat insulating and sound insulating effect by vacuum, and an apparatus and method for manufacturing the same.

Insulation of the outer wall of the building is recognized as an essential requirement for energy saving. It has been reported that the energy required for heating and cooling the building can save more than 50% of the total energy through the insulation of the outer wall of the building and the window. Therefore, building exterior wall insulation is considered to be more important.

Existing building exterior wall insulation materials include polyurethane foam foaming agents such as CFC, styrofoam, and glass wool, and are superior in thermal insulation performance. They are used for vacuum insulation panels (VIP) and aerogels ). The insulation performance of vacuum insulation panel filled with glass fiber core is evaluated to be 16 times higher than that of glass fiber and superior in heat insulation performance than polyurethane foam or styrofoam. The structure of a vacuum insulation panel in general is a shielding material for maintaining the degree of vacuum in the interior, which is made of a highly rigid casing made of a synthetic resin or metal and a core material filled in the casing, and the inside of the casing has a structure for maintaining vacuum. As the core material, organic or inorganic powders or fibers are used, and polymer resins are used. However, they have a disadvantage in that the insulation performance is deteriorated in the case of environmental problems and long-term use.

The advantage of vacuum insulation panels is that they have high insulation effect, excellent fire resistance and heat resistance, and excellent soundproofing function. However, since the price is high and the rigidity is high, the weight of the panel increases, the panel size is limited, and the heat insulating function is completely lost due to partial damage (for example, vacuum fracture).

The sealing members 7 and 9 are elastic and air-tight materials such as rubber or urethane. Of course, any type of material can be used if it can be kept confidential.

The upper and lower ends 3a and 3b of the plate member 3b extend more than the ribs 11 and the sealing member 11 covers both ends 3a and 3b of the plate member 5a and 5b, And the end portions 11a and 11b of the ribs. The sealing members 7 and 9 are fixed by bending and wrapping the upper and lower plates 3a and 3b, 5a and 5b so as not to flow or be detached therefrom.

The vacuum insulation board according to the present invention has a structure in which an elongated vacuum chamber S is continuously provided along the longitudinal direction with ribs interposed therebetween. The width of one vacuum chamber S corresponds to the spacing of the ribs 11 and can be adjusted as needed.

As shown in Fig. 6, in order to assist the sealing effect of the sealing members 7 and 9, the surfaces of the sealing members 7 and 9, that is, The auxiliary seal (8) can be applied in a coating manner as a good material. Further, both edges of the plate body 1 can be covered with the outer coating 10 as a whole with a resin having good adhesion

Hereinafter, a method or apparatus for manufacturing the above-described vacuum insulation board will be described with reference to Figs. 7 to 13. Fig.

The structure of the vacuum insulation board or plate body 1 is the same as described above, so repeated description is omitted.

First, a description will be made with reference to FIG. The base 21 is placed horizontally and fixed on the plate main body 1. The rib cutting portion 23 cuts or abrades the ribs 11 at both ends in the longitudinal direction of the plate main body 1 with a predetermined width L to remove the ribs. The rib cutting portion 23 includes a cutting blade 24 or a grinder that is installed in the horizontal direction and rotates about a vertical axis, a motor 23a for rotating the cutting blade 24, And a motor driving unit (not shown). The motor driving section drives the cutting edge 24 along the longitudinal direction and the width direction of the plate body 1 and can also be driven in the thickness direction of the plate body. The rib cutting portion 23 can use various cutting methods such as laser cutting. As the rib 11 is cut to a predetermined width L, a space S 'capable of seating the sealing member is provided.

This will be described with reference to Figs. 8 to 10. Fig. The sealing member 7 or 9 is automatically inserted into the edge space S 'manually by the operator or by the sealing member feeder 25.

The bent portions 27 bend the edges 3a, 3b, 5a and 5b of the upper and lower plates at both ends in the longitudinal direction of the plate body so that the sealing members 7 and 9 can be firmly fixed, , 9).

The bent portion 27 includes a folding plate 28 and a folding plate operating portion 27a for moving the folding plate 28 in the forward and backward directions and the vertical direction. The air gap between the sealing members 7, 9 and the end portions of the plate member 1 is eliminated by the bent portions 27 as shown in Fig.

Hereinafter, the vacuum forming unit will be described with reference to Figs.

In the state of FIG. 10, the vacuum forming portion 29 draws air inside the unit chamber S sealed by the sealing members 7, 9. The vacuum forming portion 29 performs an operation of inserting the suction needle 31 into the sealing members 7 and 9 and then extracting the air inside the plate member main body 1.

The vacuum forming part 29 is connected to the vacuum pump 35 and the vacuum pump 35 and is connected to a vacuum tube 33 which is moved back and forth along a rail 37 provided along the longitudinal direction of the plate body 1 A plurality of suction needles 31 fixed toward the plate main body 1 at intervals along the longitudinal direction of the vacuum tube body 33 and a vacuum tube body starting portion for starting the vacuum tube body 33. A moving block 39 for moving along the rail is provided at the bottom of the tube body 33.

The suction needle 31 has the same construction as the injection needle used in the syringe. When the vacuum pump 35 is activated, external air is introduced into the vacuum pipe 33 from the suction needle 31. Therefore, the vacuum tube casing can be operated so that the end of the suction needle 31 penetrates the sealing members 7 and 9 and enters the chamber S (see Fig. 12). In this state, the vacuum pump 35 sucks air in the chamber S to make it into a vacuum. When the degree of vacuum reaches the designed level, the vacuum pump 35 stops operating and the tube unit 33 is moved backward so that the suction needle is separated from the plate body 13 (see FIG. 13).

In order to improve the working speed, the vacuum pipe body 33 and the suction needle 31 are provided at both ends of the plate body 1, and the air inside the plate body 1 can be sucked from both sides simultaneously.

With this configuration, a vacuum can be formed inside the sheet material body by the sealing member. An auxiliary sealing 8 can be applied to the surface of the sealing member, that is, the surface to which the suction needle is inserted, as a material that can be easily fused with the sealing members 7 and 9 to assist the sealing effect of the sealing members 7 and 9 . Further, both edges of the plate body 1 can be covered with the outer coating 10 as a whole with a resin having good adhesion

As described above, the auxiliary seal 8 and the outer coating 10 are each formed using a separate apparatus.

Since the present invention also has methodical elements, it is also within the scope of the present invention to cover the vacuum forming method of the insulating plate. The method is summarized as follows.

The method includes a first step of securing a sealing member to both ends of the plate body to seal the inside of the plate body, And a second step of drawing the air inside the plate material body 1 by passing the air intake needle 31 similar to the injection needle into the sealing members 7 and 9 through the sealing members 7 and 9.

Here, the first step may be composed of three detailed steps as follows.

First, the plate body is horizontally fixed, and the ribs 11 at both ends in the longitudinal direction of the plate body 1 are cut or polished to have a constant width.

Second, rod-like sealing members 7 and 9 made of rubber, urethane or silicone are inserted into the space S 'provided as the rib 11 is cut to a predetermined width L.

Third, the upper and lower plate edges at both ends in the longitudinal direction of the plate main body 1 are bent and the sealing members 7 and 9 are pressed and fixed.

Then, after the second step, the auxiliary seal 8 is selectively coated on the surface of the sealing member to complement the needle hole of the sealing member to complete the insulating plate.

Here, the method of fixing the sealing member in the first, second, and third steps may be replaced by another method. What is important is to fix the sealing member to both ends of the plate main body.

According to the vacuum insulation board of the above construction, although the vacuum insulation board is cut as shown by the dotted line in FIG. 1, the remaining chamber is kept in vacuum, so that the insulation effect of the vacuum insulation board does not deteriorate. That is, the vacuum insulation board can be cut and used. Since the rigidity is basically excellent as a profile shape, there is provided a vacuum insulating plate material which does not need to take measures for stiffening reinforcement.

Hereinafter, another embodiment of the present invention will be described with reference to Figs.

According to this embodiment, a method different from that described above can be used as a method of fixing the sealing member to both ends of the plate material main body to maintain the airtightness of the inside of the plate material main body. 14, a sealing member is first inserted into a frame 51 having a side face shape, and the sealing member is fitted to the edge of the plate body 1, And the like. A window 53 is provided on the front surface of the frame 51 at intervals corresponding to the intervals of the ribs 11 so that the intake needle 31 can be inserted. The sealing member can not be easily released by the support piece 55 on the front surface of the frame 51. [

The configuration shown and described above is merely a preferred embodiment based on the technical idea of the present invention. It will be understood by those skilled in the art that various changes and modifications may be made without departing from the scope of the present invention.
