In particular, in order to produce the panel 100 of the type shown in FIG. 5, the raw materials should be separately supplied to the upper and lower portions with the fiber sheet 57A interposed therebetween. The added composition should also be metered in to form the desired thickness of the chromophoric layer.

With reference to Figure 1b, 2, 3a, and 3b will be described in detail with respect to the metering unit 30 and the molding unit 50.

First, a material for forming the lower composition molding layer 101A of the panel 100 is introduced into the lower conveyor 53 of the molding part 50 from the mixer 21 via the intermediate conveyor 25a. The raw material of the conveyor 25a is weighed in the fixed quantity supply part 31 for the lower surface of the fiber sheet 57A, processed and approved by the control part, and then transferred to the lower conveyor 53 of the molding part 50.

In the front portion of the lower conveyor 53, only the lower conveyor is arranged without overlapping with the upper conveyor 51. This is to introduce the fiber sheet 57A into the building panel 100 as described below. It is essential.

The lower conveyor has a plurality of supporting rollers (not specified) and a heating roller 55a constituting the heating means 55 between the tail drum 53A at the front end and the driving drum D2 at the rear end thereof. The belt 53a is provided.

The belt 53a is preferably made of a metal material having good heat resistance and thermal conductivity in order to perform heating together with pressurization.

It is preferable that both sides of the belt 53a are continuously formed over the release preventing plate (not shown) belt having a predetermined height so that the edges are formed vertically while ensuring the thickness of the panel to be molded.

When the release preventing plate is provided, the upper conveyor 51 belt 51a of the pressing means 50A should have a width that can fit inside the release preventing plate.

The raw material transferred from the fixed quantity supply part 31 for the lower surface of the fiber sheet to the lower conveyor 53 should be spread evenly to cover the fiber sheet 57A on the flattened material.

The flattening unit 40 introduced for this purpose, as shown in the figure, has a spiral blade and a spreading roller 41a which is turned on / off by a control unit, and is located at the rear of the spreading roller and ascends and descends. It consists of a reciprocating panel 43a which presses the raw material to some extent and flattens the unfolded top surface of the raw material.

The reciprocating panel 43a may be in the form of lifting up and down by a cam rotated by a motor, it is possible to introduce other alternative means.

If necessary, the upper portion of the lower conveyor 53 belt 53a in the forming section 50 may be provided with a pressure roller after the reciprocating panel 43a or by replacing the reciprocating panel to pressurize the raw material more firmly. May be considered.

Next, in the manufactured panel 100, a fiber sheet supply part 57 for introducing the fiber sheet 57A onto the lower composition molding layer 101A is arranged.

As can be seen in more detail in Figure 3b, the supply portion 57 is a two-way directional roller 57b (57c) from a supply roller (57a) wound around a special fiber sheet (57A), such as FRP in the form of a mesh It is released along the lower raw material layer conveyed through Such a fiber sheet is preferably supplied in a stretched state by tension.

Thereafter, the upper portion of the fibrous sheet 57A was metered by the metering feeder 33 for the upper surface of the fibrous sheet through the intermediate conveyor 25b from the mixer 21 to form the upper forming layer 101B of the manufactured panel. After that, the sheet 57A is transferred to the upper portion,

In addition, after the fixed-quantity supply part 33, the spreading roller 41b and the reciprocating panel 43b forming the flattening part 40 are provided on the lower conveyor 53.

Although not shown after the flattening unit 40, if a color is to be introduced into the outer surface of the panel, the third intermediary conveyor and the third quantity supply unit 35 (see FIG. 2) are applied, and then unfolded by the flattening means. You can do that.

The reason for separately introducing the coloring layer 103 into the panel 100 manufactured as shown in FIG. 5 is that the particle size of the main components including plastic foamed vermiculite is about 4 to 6 mm in the case of a ceiling board. Even if you mix raw materials and pigments, it is impossible to express even colors.

Particle size is made about 1 ~ 2mm through a separate pulverizable mixer 23, and the pigment is mixed therein, and corresponds to a thickness of about 1/10 ~ 1/20 of the total thickness of the manufactured panel 100 When the color layer 103 is formed, an even color expression and excellent texture can be obtained, and the consumption of expensive pigments can also be drastically reduced, which is a great help in lowering the product cost, which is a ground problem in competition with products such as gypsum board. This can be

As described above, the quantitative supply unit 30 in FIG. 2 may be made of a quantitative supply unit for the lower surface of the fiber sheet 31, the upper surface of the fiber sheet 33, and the exposed surface 35 based on the panel 100 of FIG. 5. have.

In this way, the distance between the conveyors in the molding section 50 formed of the upper and lower conveyors 51 and 53 becomes narrower from the front to the rear, so that the desired panel thickness is finally obtained by the gradual pressing through the entire panel. It is suitable for achieving even density and durability.

In particular, as can be confirmed in more detail in Figure 3b, it is preferable that the lower conveyor 53 is horizontal and the upper conveyor 51 is inclined in an obliquely descending form,

In addition, all or part of the rollers arranged under the belt 51a and 53a adjacent surfaces of the upper and lower conveyors 51 and 53 to perform pressurization are composed of heating rollers 55a, at a temperature of about 250 to 300 ° C. Pressurization may be performed while heating to allow panel manufacture.

When only some of the rollers are the heating rollers 55a, the rollers that are purely pressurized and the heating rollers 55a which perform the pressing and heating may be alternately arranged.

At the rear of the forming unit 50, the heating port region H, which is composed of a plurality of heat transfer heaters 55b, is formed so that the heating means 55 together with the heating roller 55a perform purely heating. .

After the rear end driving drum (D1) (D2) of the molding unit 50 is exposed to the maturation conveyor 59 of a predetermined length in order to increase the molding strength while cooling the panel at room temperature.

In spite of the desorption plate of), cut off the side of the remaining panel so that it corresponds to the desired width or the width of certain building standard (eg 900mm).

In consideration of panel side cutting at the cutting portion 81, the width of the panel initially manufactured in the molding portion 50 is preferably wider than the width of the final panel, for example, about 50 to 150 mm.

In addition, in Figure 4c, the cutting portion 83 is cut to a predetermined length for the final size of the panel is provided, and performs the cutting operation to form a square or rectangle, the final panel,

Thereafter, the final panels cut at the stacking portion 90 made of a known table lifter are laminated.

The table lifter constituting the stacking unit 90 is lowered by the panel thickness by a hydraulic cylinder (not shown) which is lifted and lowered by the control unit so that the second panel is mounted on the table after the first panel is placed on the table. Then repeating again the panel thickness is lowered again so that the third panel is on top of the second panel, and finally N panels are stacked on the table,

The laminated panel is packaged by an automated facility or moved to the packaging unit using a forklift, etc., and then packaged.

The table lifter is then initialized with the table returned to its initial position.

In the apparatus for manufacturing a building panel as described above, the delivery and the conveying speed of the raw material and the panel are controlled by the controller to ensure sufficient time for the panel to be transported and the smooth and continuous loading packaging in the loading unit 90. .
