Opening-sealing apparatus for honeycomb molded body, opening-sealing apparatus for honeycomb fired body, method of filling plug material paste, and method of manufacturing honeycomb structured body

摘要

An opening-sealing apparatus for a honeycomb molded body comprising:;a paste filling device equipped with a paste filling unit having an opening-sealing mask in which a number of openings are formed at predetermined positions and a paste supplying unit;;an image pickup device for picking up an image of the end face of the honeycomb molded body; and;an image analyzing device for analyzing the image obtained by the image pickup device, wherein;the image analyzing device analyzes the positions of the cells based upon the image of the end face picked up by the image pickup device; the opening-sealing mask is made in contact with the end face of the honeycomb molded body in such a manner that the positional error between the openings of the opening-sealing mask and the cells of the honeycomb molded body is reduced to a minimal level; and the plug material paste, which has been supplied from the paste supplying unit to the paste filling unit, is injected through the opening-sealing mask and filled in the end portion of the cells.
