Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a method of manufacturing an inorganic fiberboard having a reinforcing rim material.

Inorganic fiberboard (hereinafter referred to as fiberboard), which is made by collecting inorganic fibers such as glass fiber, is widely used as a heat insulating material, sound absorbing material, and sound insulation material, but since this fiberboard is an aggregate of fibers, the fiber density is low. Even if the fiberboard has a fairly high density, it has the property of deforming when external force is applied to it. For example, when fiberboard is used as a filling material in the partition walls of buildings, inside doors, etc., the thickness of the outer panel must be made considerably thicker. The drawback is that the outer panel easily deforms when external force is applied.

Conventionally, in order to prevent this, as shown in FIG. However, in order to fill the reinforcing rim material 1 formed in a lattice shape with the fiber material 2, it is necessary to divide the fiber material 2 into small pieces and fill them. However, there is no reasonable way to fill it, and it must be done mainly by hand.

As a result, there are disadvantages such as increased man-hours and ultimately an expensive product.Also, as shown in FIG. A type in which the paper honeycomb 5 is covered with an outer plate 1 has also been used, but in this case as well, it is difficult to fill the paper honeycomb 5 with the fiber material 6, and there are drawbacks such as poor heat insulation and sound absorption properties.

The object of the present invention is to eliminate the drawbacks of the above-mentioned conventional methods, and to provide a method for manufacturing an inorganic fiberboard having a reinforcing rim material, which has a simple structure, can be mass-produced, and is inexpensive. be.

This invention will be described with reference to embodiments shown in the drawings.

As shown in FIG. 3, the fiberboard 8 is made by separating a plurality of reinforcing rim materials 10 at a necessary distance P from a plate-shaped fiber material 9 having a required thickness and in a longitudinal direction perpendicular to the plane thereof. The fiberboard 8 formed in this way is attached to the outer panel 11.
However, since the external force applied to the outer panel 11 is supported by the reinforcing rim material 10 which is bonded at a distance, the outer panel 11 does not deform, and therefore the thickness of the outer panel 11 can be reduced. It is possible to obtain a lightweight, sound-absorbing and heat-insulating material.

The reinforcing rim material 10 to be bonded to the fiberboard 8 may be made of paper, glass tape, metal plates such as aluminum, band steel, galvanized steel plates, or plastic, and these are selected as appropriate depending on the purpose of use. .

Further, the shape of the reinforcing rim material 10 is not limited to the belt shape as shown in FIG. As shown in FIG. 1, notches 13 are provided at desired intervals on one side edge of the reinforcing rim material 10, and furthermore, as shown in FIG. The reinforcing rim material 10 may be of any type as long as it has a thin-walled shape that is flexible in the longitudinal direction, and its selection is also dependent on the use. It is determined as appropriate depending on the purpose.

Next, the manufacturing process of the fiberboard 8 will be explained with reference to FIGS. 8 to 10.

As shown in FIG. 10, molten glass 15 is drawn out from a nozzle 16 and made into fibers by a known fiberizing method. Fibers 17 are collected on a conveyor 18 by spraying an adhesive such as phenol resin, and are sandwiched between rolls 19. A fibrous material 9 having a certain thickness and width is formed by pressing using a known method.

The fibrous material 9 thus formed is conveyed via conveyors 18 and 20 to a rotary cutter 21 and a rubber roller 2 that receives it.
It will be moved between 2.

This rotary cutter 21 has a plurality of disc-shaped blades 2 on a rotating shaft 23.
4 are installed at a required interval P, and the interval P is the third
It has the same value as the interval P shown in the figure, and can be adjusted to any width by changing the mounting position of the rotary cutter 21 and the number of the plurality of disk-shaped blades 24 as necessary.

The fiber material 9 is divided into a plurality of pieces (five pieces in the drawing) in the transport direction while being moved by the rotary cutter 21, and after passing the position of the rotary cutter 21, it is divided into a plurality of narrow fiber materials 9a.

The fiber materials 9a thus divided are further separated from each other by a separation roller 25 to create a gap, and after being separated, each of the narrow fiber materials 9a is moved by an index roller 26 (or an index conveyor) to a convergence conveyor. 27,28゜29
The converging rollers 30 apply pressure from both the vertical and horizontal directions to form a single unit again. During this time, the separation rollers 25 move the sheets to a position where they are lifted upward (or downward) with respect to the direction of travel.

This separation roller 25 also has the role of a benzene crawler that bends the fiber material 9a.

On the other hand, the reinforcing rim material 10 is formed at each confluence point 31 of the narrow fiber material 9a.
At this time, the reinforcing rim material 10 is formed into a belt-like material whose width W is adjusted in advance to a value approximately equal to the thickness of the narrow fiber material 9a. The reinforcing rim material 10 is coated with a known adhesive application device 32, 3.
3 (for example, using a spray can or an immersion bath), the adhesive is applied to the surface of the fiber material 9a, and the adhesive is applied to the side surface of the narrow fiber material 9a using a pressure roller 34, and the adhesive is applied to the side opposite to the adhesive surface. It is inserted into the confluence point 31 of the material 9a.

Therefore, the number of reinforcing rim materials 10 to be supplied is determined depending on the number of fiber materials 9a.

The fiberboards 8 to which the reinforcing rim materials 10 are separated and adhered are translated and pressed in the width direction by the focusing conveyors 27 and 2B, thereby joining each other and becoming an integral body. 2γ.

The position of 28 can be adjusted by moving its tip as shown by the dashed line.

Further, the rollers 30, 35 are provided so that the surfaces of the fiber materials 9a become flat when they are integrated.

The fiberboard 8 to which the reinforcing rim material 10 has been bonded is further advanced and heated in a curing heating furnace 36, and the adhesive between the fibers and the reinforcing rim material 10 is cured and completely coalesced into one piece.

Note that the adhesive applicator 31 is used to apply the adhesive again near the entrance of the curing heating furnace 36 if necessary.

The fiberboard 8 whose adhesive has been cured in the curing heating furnace 36 is cut by the cutting machine 3.
8 to cut it into the required length and make it into a product.

Further, the surface of the fiberboard 9 to which the reinforcing rim material 10 is adhered can be covered with a decorative board 39 such as aluminum foil, as shown in FIG.

In this case, adhesive is applied to one side of the surface decorative board 39 from a lower position by an application device 40 and is continuously supplied.
It is bonded to one side of the fiberboard 8.

Note that the manufacturing method of the present invention can also be used for a band-shaped fiber material 41 in which the adhesive for adhering the fibers to each other has already been hardened.

That is, it is also possible to process the fiber material 41 as shown in FIG. 11 by rolling it up and moving it onto the conveyor 18, but in this case, since the fiber material 41 does not contain uncured adhesive, the curing furnace 36 Only the adhesive used to bond the reinforcing rim material 10 is cured.

Note that the number of subdivisions of the fibrous material is not limited to the five divisions described above, but can be easily divided into any number by appropriately changing the number and spacing of the disc-shaped blades of the rotation force.
This is appropriately determined depending on the width required for the fiberboard.

The present invention is as described above, in which a band-shaped inorganic fiber material is cut and separated into a plurality of pieces, a reinforcing rim material is continuously inserted between the separated pieces of fiber material, and the reinforcing rim material is integrally bonded. Since the integrated fiber material and reinforcing rim material are cut, it is possible to easily produce fiberboard of various quality, and in addition,
Its productivity is high and therefore the product can be supplied at low cost,
In addition, since the fibers separated during the manufacturing process are separated to create gaps between each fiber, the reinforcing rim material can be easily inserted without any trouble, and the number of fibers separated can be changed. Since the number of reinforcing rim materials inserted can be easily changed to various numbers, this has the effect that fiberboards with various strengths can be manufactured.
