A fixing jig includes a pedestal including a placing surface on which a columnar honeycomb structure is placed, holding members fixed to the pedestal and configured to hold a side surface of the honeycomb structure placed on the placing surface, and drawing and fixing members fixed to the pedestal and configured to draw and fix the surface on the pedestal side in the outer circumferential portion of a mask placed on the honeycomb structure. Consequently, the fixing jig can fix the honeycomb structure and the mask aligned with each other and is less likely to hinder the alignment of the mask.

Fixing jig, fixing method, and honeycomb filter production method

A camera is used to take an image of an end surface of a honeycomb structure gripped by a hand. Based on the image, an initial rotation angle of the honeycomb structure around a vertical axis at a reference position where the image has been taken is recognized. An arm turning section is driven to convey the honeycomb structure gripped by the hand from the reference position to above a plugging mask. A rotation angle required to adjust the rotation angle of the honeycomb structure on the plugging mask to a desired final rotation angle is acquired based on the initial rotation angle recognized at the reference position and a rotation angle of the honeycomb structure around the vertical axis associated with the driving of the arm turning section from the reference position to above the plugging mask. The honeycomb structure is rotated based on the required rotation angle.

Sealing device

A method for manufacturing a honeycomb-structured object having a plurality of through holes having ends thereof plugged, including a step of pressing a plugging material against one end surface of a honeycomb-structured objecthaving a plurality of through holesby a plateto fill one ends of the through holeswith the plugging material; and a step of protruding a part of a portion in the plateopposed to the one end surface of the honeycomb-structured objecttoward the one end surface to pull the other part of the portion in the plateopposed to the one end surface of the honeycomb-structured objectand the one end surface away from each other.
