Description

Description: TECHNICAL FIELD The present invention relates to a method for producing a laminate suitable for a honeycomb product and an apparatus for producing a laminate.

(Prior Art) FIG. 4 is a perspective view of a laminated plate structure, FIG. 5 is a perspective view of a honeycomb, and a plurality of long flat plates W1, W2, W3. A laminated structure 100 is formed from the adhesives 101 applied in a staggered manner and in a band shape between each other, and is stretched in the directions indicated by the arrows to form a honeycomb-shaped honeycomb 102 shown in FIG. You. However, this honeycomb 102 is obtained by plastically deforming the laminated plate structure 100 shown in FIG. 4 and then dividing the laminated plate structure 100 in the plate width direction (vertical direction in the drawing), and has a reduced width.

As a technique for applying the adhesive in the belt shape, a silk screen method and a gravure roller method are conventionally known.

In the silk screen method, a mask material with a hollow groove is pasted on the lower surface of the silk screen, a one- or two-part adhesive is applied from the upper surface of the silk screen, and applied in a strip shape on a long flat plate below. is there. The portion of the mask material is an uncoated portion, and the adhesive is applied only to the opened groove portion. That is, it is a technique in which the printing ink of the silk screen printing method is replaced with an adhesive.

Similarly, the gravure roller method is a technique in which the printing ink of the gravure roller printing method is replaced with a one-part or two-part adhesive material.

(Problems to be Solved by the Invention) The silk screen method and the gravure roll method described above
It is technically stable because it is based on printing technology. However, since the adhesive is a two-part adhesive between one liquid, there are problems such as control of their concentration and viscosity, cleaning of the surface of the long flat plate and flatness, and deterioration of the working environment due to evaporation of the solvent. There is. Furthermore, the time required for the plates to polymerize after application (the solidification of the adhesive is not good) is limited,
Coating and slab polymerization operations must be performed promptly.

Further, it is difficult to match (align) the screen and the gravure roll with the long flat plate. In particular, in the gravure roller method, matching is easy when applied in a strip shape in the longitudinal direction of a long flat plate, but as in the present object,
It is extremely difficult to apply in the width direction.

And, the clean and gravure rolls require a formula removal operation and a maintenance operation so that the adhesive does not adhere.

Furthermore, one-part or two-part adhesives do not have high shear peel strength.

Therefore, the present invention aims at facilitating the work, improving the work environment, improving the adhesive strength, and the like.

(Means and Actions for Solving the Problems) In order to achieve the above object, the method of the present invention prepares a plurality of long tape-like films for bonding, and sets a predetermined pitch among these tape-like films. The first group was arranged, and the second group was shifted by 1/2 pitch from the first group. First, the tape-shaped film of the first group was placed on the lowest long plate. A part of the tape-like film is interposed between the first and second long flat plates by partially abutting the second long flat plate thereon, and then the second long flat plate is interposed. The second group of tape-shaped films is placed between the second and third long flat plates by abutting a part of the second group of tape-shaped films on the flat plate and stacking a third long flat plate thereon. Then, the tape-shaped film of the first group is placed on a third long flat plate. The first group of tape-like films is interposed between the third and fourth long flat plates by abutting a part of the remaining portion and overlaying the fourth long flat plate on the fourth long flat plate. The second group is interposed between the fourth and fifth long flat plates by abutting a part of the remaining portion of the tape film of the second group on the long flat plates and stacking the fifth long flat plate thereon. A long enough tape-like film is interposed on a plurality of laminated long flat plates in a zigzag manner so that the tape-like film is interposed, and then these are heated to melt the tape-like film. Thereby, the long flat plates are bonded to each other.
