example 1

[0364]Powder of α-type silicon carbide having an average particle diameter of 10 μm (250 kg), powder of α-type silicon carbide having an average particle diameter of 0.5 μm (100 kg) and an organic binder (methyl cellulose) (20 kg) were mixed to prepare a mixed powder.

[0365]Next, separately, a lubricant (Uniloop, made by NOF Corp.) (12 kg), a plasticizer (glycerin) (5 kg) and water (65 kg) were mixed to prepare a liquid mixture, and this liquid mixture and the mixed powder were mixed by using a wet mixing machine so that a wet mixture was prepared.

[0366]Next, this wet mixture was transported to an extrusion molding machine by using a transporting apparatus, and charged into a raw material charging port of the extrusion molding apparatus.

[0367]The wet mixture was then extrusion-molded into a molded body having the same shape as shown in FIGS. 14(a) and 14(b) except that ends of the cells had not been sealed.

[0368]Next, after the honeycomb molded body had been dried by using a drying a...

example 2

[0380]By carrying out basically the same processes as those up to the manufacture of the honeycomb fired body of Example 1, a honeycomb fired body was manufactured.

[0381]Provided that, the intermittent moving embodiments of the jig assembling belt conveyor 212 comprising a degreasing jig assembling apparatus 211 and the jig disassembling belt conveyor 232 comprising a degreasing jig disassembling apparatus 231 in the degreasing jig circulating apparatus 210 were changed as follows: upon transporting, the belt conveyors were moved at a moving speed of 3.0 m / min, and upon shifting from the moving state to the stopped state, the moving speed of 3.0 m / min was first lowered to a moving speed of 1.5 m / min (moving speed before the stoppage), and the belt conveyers then shifted to stopped state.

[0382]In the present example, after the cover member had been detached, the degreased honeycomb molded body was visually observed, and no honeycomb molded body having defects such as cracks was found...

Abstract

A degreasing jig assembling apparatus includes a robot arm and a table or a conveyor on which a degreasing jig including a bottom plate and a cover member is placed. A ceramic molded body is mounted on the degreasing jig upon degreasing the ceramic molded body. The ceramic molded body is mounted on the degreasing jig on the table or the conveyor. The degreasing jig assembling apparatus further includes a molding body mounting mechanism and a cover member. The molding body mounting mechanism mounts the ceramic molded body at a predetermined position on the bottom plate placed on the table or the conveyor by using the robot arm. The cover member attaching mechanism attaches the cover member to the bottom plate in a manner so as to cover the ceramic molded body mounted on the bottom plate.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application claims priority under 35 U.S.C. §120 to PCT Application No. PCT / JP2006 / 309116, filed May 1, 2006, entitled “DEGREASING JIG ASSEMBLING APPARATUS, DEGREASING JIG DISASSEMBLING APPARATUS, DEGREASING JIG CIRCULATING APPARATUS, METHOD FOR DEGREASING CERAMIC MOLDED BODY, AND METHOD FOR MANUFACTURING HONEYCOMB STRUCTURED BODY.” The contents of this application are incorporated herein by reference in their entirety.BACKGROUND OF THE INVENTION[0002]1.
