METHOD OF MANUFACTURING HONEYCOMB STRUCTURED BODY

摘要

In a method of manufacturing a honeycomb structured body, a ceramic block is formed by binding multiple pillar-shaped honeycomb fired bodies with adhesive layers interposed therebetween. The multiple pillar-shaped honeycomb fired bodies are bound on a support by piling up the multiple pillar-shaped honeycomb fired bodies successively. A placing position where a primary honeycomb fired body is to be placed is determined. A position of an end face of at least one secondary honeycomb fired body is fixed by applying force to the end face of the at least one secondary honeycomb fired body. The primary honeycomb fired body is placed on the placing position with the position of the end face of the at least one secondary honeycomb fired body being fixed. The fixing further includes first positioning or second positioning based on a number of the at least one secondary honeycomb fired body before the fixing.

1. A method of manufacturing a honeycomb structured body, comprising:
forming a ceramic block by binding multiple pillar-shaped honeycomb fired bodies with adhesive layers interposed therebetween, the multiple pillar-shaped honeycomb fired bodies each having cells longitudinally disposed in parallel with each other and cell walls between the cells, each cell wall of the multiple pillar-shaped honeycomb fired bodies having a thickness of about 0.1 mm to about 0.2 mm and each peripheral wall of the multiple pillar-shaped honeycomb fired bodies having a thickness of about 0.25 mm to about 0.5 mm, the forming the ceramic block comprising:
binding the multiple pillar-shaped honeycomb fired bodies on a support by piling up the multiple pillar-shaped honeycomb fired bodies successively, the binding comprising:
determining a placing position where a primary honeycomb fired body is to be placed;fixing a position of an end face of at least one secondary honeycomb fired body by applying force to the end face of the at least one secondary honeycomb fired body, the at least one secondary honeycomb fired body being a honeycomb fired body whose side face is to be opposite to a side face of the primary honeycomb fired body below the placing position;placing the primary honeycomb fired body on the placing position with the position of the end face of the at least one secondary honeycomb fired body being fixed; andthe fixing further comprising:
first positioning or second positioning based on a number of the at least one secondary honeycomb fired body before the fixing, the at least one secondary honeycomb fired body each being placed on a position where a side face of the at least one secondary honeycomb fired body is opposite to a side face of the primary honeycomb fired body to be placed; andwhen the at least one secondary honeycomb fired body includes one secondary honeycomb fired body, the first positioning being performed to fix a position of an end face of only the single secondary honeycomb fired body, orwhen the at least one secondary honeycomb fired body includes multiple secondary honeycomb fired bodies, the second positioning being performed to fix positions of first end faces of only the multiple secondary honeycomb fired bodies so as to align the positions of the first end faces of the multiple secondary honeycomb fired bodies.
