BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, preferred embodiments of a honeycomb manufacturing apparatus and a honeycomb manufacturing method according to the present invention will be described in detail with reference to the accompanying drawings.

The present invention simplifies the manufacturing process and saves time and cost for manufacturing honeycomb.

The honeycomb manufacturing apparatus according to the present invention comprises a feeder (10) for feeding a raw material plate (1) for producing honeycomb formed with a plurality of pores wound on a roller to a downstream end thereof; A cutting device (20) for cutting the raw plate fed by the feeding device to a desired width; A heating device (30) for heating a band-shaped band (120) which is fed to the cutting device in a cut state; A net differential pressure forming device 40 for forming a bent groove 120g forming a hexagonal hole by pressing a soft band heated by a heating device; And a fusing device 50 for fusing together the bands formed with the bending grooves so that the hexagonal holes 100h are formed between the adjacent bands.

The present invention relates to an apparatus and a method for manufacturing honeycomb honeycomb by cutting, bending and thermally fusing a raw material plate 110 as a raw material for manufacturing a honeycomb according to the present invention. And includes a feeder 10 as shown.

The honeycomb manufactured by the manufacturing apparatus of the present invention may be made of various materials, but preferably synthetic resin or the like may be used, and more preferably, the honeycomb is made of a foamed resin having a large number of bubbles. Accordingly, the raw material plate 110 may be a foamed resin plate having bubbles.

As shown in FIGS. 1 to 3, the raw material plate 110 is supplied while being wound around the rollers, and the supply device 10 rotates the rollers to supply the raw material plate wound on the rollers to the downstream device. That is, the feeder 10 may be composed of a motor or the like which simply rotates the rollers to unwind the raw material plate wound on the rollers from the rollers.

The raw material plate unrolled from the roller by the driving of the feeding device 10 is fed to the cutting device 20 at the downstream end.

The cutting device 20 cuts the raw material plate and cuts the band 120 to a width corresponding to the thickness of the honeycomb desired to be manufactured.

The band 120 cut by the cutting device 20 passes through the molding device 40 and a bending groove 120g is formed as shown in Fig. (Honeycomb 9100 having a hexagonal hole 100h as shown in Figs. 5 and 6).

It is preferable that the band formed by cutting by the cutting device 20 is hard and hard to be molded so that it is softened. Accordingly, it is preferable to further provide a heating device 30 at the front end of the molding device 40 to soften the band.

The heated band 120 is softened in the heating device 30 so that molding can be performed by a small external force. Of course, if excessive heat is applied to the heating device, the band may become too soft and lose its shape, so the degree of softening of the band should be controlled by controlling the driving of the heating device. A detailed description thereof will be omitted.

The molding apparatus 40 may be modified in various ways. For example, as shown in FIG. 4, the molding apparatus 40 may include an upper mold 42 mounted on an upper portion of a fixed lower mold 41, The interval between the bent grooves 120g formed in the band 120 can be adjusted by controlling the lifting and lowering period of the mold so that the size and the interval of the finally formed hexagonal hole 100h of the honeycomb can be adjusted.

5 and 6, the bending grooves 120g are horizontally arranged by the molding apparatus 40 as shown in Figs. 5 and 6. When the bending grooves are opposed to each other, the protruding portions are thermally fused to each other The bent grooves 120g facing each other between the bands form a pair of hexagonal holes 100h.

The fusing device 50 is provided as means for thermally fusing the bands to each other.

On the other hand, the band formed with the bending grooves by the molding apparatus 40 is heated and softened by the heating device, and if the bending grooves 120g are immediately subjected to pressure in this state, the bending grooves 120g may be deformed To this end, a buffer unit 60 is further preferably provided between the molding apparatus and the fusing apparatus.

As described above, the buffer unit 60 is a means for cooling the band in which the bent groove 120g is formed. In this case, the buffer unit 60 may be a space that is simply opened to expose the band by a predetermined distance in the atmosphere, A blowing fan, etc. may be installed.

As shown in FIGS. 5 and 6, the honeycomb 100, in which the bands are fused together by the fusing device 50 to form the hexagonal holes 100h, Respectively. Although the hexagonal hole is described as an example in the above description and drawings, it may be a circular or polygonal hole.

Hereinafter, a method for manufacturing a honeycomb using the apparatus configured as described above includes the steps of: preparing an original plate for manufacturing a honeycomb having a plurality of pores; A band manufacturing step of cutting the band with a width equal to the thickness of the honeycomb manufactured by cutting the raw plate; Molding the cut bands into a tangential groove in a width direction by molding the cut bands in a net pressure method; And a heat fusion step of laminating the bands formed with the bending grooves so that the bending grooves face each other, and then heating the bending grooves to form one hexagonal hole by pressurization.

Since the manufacturing method of the honeycomb manufacturing method according to the present invention has already been described in the above description of the apparatus, a detailed description thereof will be omitted, and only the portions lacking description will be described.

As described above, the honeycomb manufactured by the apparatus and the method according to the present invention can be made lighter by being made using a foaming resin, and such foaming resin can be produced using a conventionally produced one, The description of the process or method is omitted.

It is preferable that the band produced in the band manufacturing step is heated and softened before forming the bent groove. The method of softening the band can be achieved by heating the band using a rigging device as described above.

Further, since the band formed with the bending grooves as described above is in a softened state, the shape may be deformed by being pressed, so that it is preferable to allow the band having the bending grooves to be cooled by being left for a predetermined time.

Further, a reinforcing vane 120w may be further formed at both ends in the width direction of the band in which the bent groove is formed.

The reinforcing vane 120w not only strengthens the strength of the honeycomb itself, but also enhances the contact force with other materials. In other words, the honeycomb is usually used as a means for reinforcing the strength of the plate material by being installed between the other plate materials. When only the honeycomb holes formed on the honeycomb are bonded to the plate material when the honeycomb is laminated between the plate materials, The bonding force between the honeycombs may be lowered, so that it is preferable to further form a reinforcing vane to widen the contact area between the plate material and the honeycomb.
