Abstract

PURPOSE:To facilitate the manufacturing of the titled plate and increase the forming speed and consequently make the mass-production of the titled plate possible by a method wherein softened resin material is formed by being led between a forming roller, on the surface of which hexagonal prism pieces are arranged with gaps in honeycomb pattern, and a compression roller and, after that, hardened. CONSTITUTION:A forming roller 6, on the surface of which hexagonal prism pieces are arranged with gaps in honeycomb pattern, a compression roller 13, which is arranged so as to come close to the top surface of the piece, and driving devices 10 and 18 to rotate both the rollers are provided. Resin material 24 softened with heaters 20 is poured between the forming roller 6 and the compression roller 13 so as to be compressed and formed in the form of the gap S of the forming roller 6. The resultant formed softened resin material 24 is lowered downward with the rotations of both the rollers 6 and 13 and at the same time pulled to the compression roller side due to the negative pressure developed on the compression roller 13 side so as to separate from the forming roller 6 and, after that, further lowered down to a position between air injection pipes 22 and 22 so as to be hardened by cooling air 23.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a method for manufacturing a honeycomb structural plate and an apparatus for manufacturing the same.

(Prior Art) Conventional methods for manufacturing honeycomb structural plates include, for example, the expansion method shown in FIGS. 4 to 7, and the method shown in FIGS. 8 to 7.
The corrugation construction method shown in FIG. 10 is known.

In the expansion construction method, the adhesive 02 is applied to the surface of the metal or paper board 01 in an even band shape, and the interval m between the bands of the adhesive 02 is three times the width of the adhesive 02. Make it so.

Next, plate materials 01, 01 to which adhesive 02 was applied. ... between the bands of adhesive 02 on the upper plate 01, on the lower plate 0.
A block body 03 is formed by overlapping and adhering so that the bands of adhesive 02 of 1 are positioned.

Next, the block body 03 is cut at equal intervals n and then stretched vertically to form a honeycomb frame body 04 in which hexagonal columns having negative side lengths are continuous.

Thereafter, the honeycomb frame body 04 was sandwiched between a top plate 05 and a bottom plate 06 to produce a honeycomb structure plate.

In addition, in the corrugation method, first, a plate material 01 such as metal or paper that has the property of being plastically deformed is moved by a corrugated roller 07,
A corrugated plate material 08 is formed through the gaps between the corrugated plate materials 0 and 07.
8, 0B, ... as the valley part 0 of the upper corrugated plate material 08
9 and the peak portion 010 of the lower corrugated plate material 08 with adhesive 02.
The block body 03 is formed by adhering.

Thereafter, the block body 03 is cut at equal intervals n to form a honeycomb frame body 04, and the honeycomb frame body 04 is cut into the upper plate 05.
and a bottom plate 06 to produce a honeycomb structure plate.

(Problems to be Solved by the Invention) However, according to such a conventional manufacturing method of a honeycomb structure plate, since the plate material 01 and the corrugated plate material 08 are laminated, there are many steps from the raw material to the product in the manufacturing process. It is difficult to automate and mass-produce as there is no continuous flow of one tree.

In addition, in the expansion method, the honeycomb frame 0
4, in the corrugation method, plastic deformation is performed when forming the corrugated plate material 08, but for this reason, the materials are limited to those with the property of plastic deformation such as metal and paper, and these are not corrosion resistant.・Poor water resistance.

In addition, since it has an adhesive structure, it can be used for pre-treatment, prevention of dust adhesion, etc.
Careful attention must be paid to the adhesive surface and the quality control of the adhesive, such as selecting the adhesive, which is time-consuming, and also when forming the block body 03 and the upper plate 05. When gluing the bottom plate 06 and the gluing process 2
There was a problem in that it required multiple steps and was time-consuming.
