SHELF-PLATE CRACK DETECTING METHOD, HONEYCOMB STRUCTURE DELIVERING METHOD, SHELF-PLATE CRACK DETECTING APPARATUS, AND SHELF PLATE DELIVERING APPARATUS

摘要

A detecting apparatus includes: a lifting mechanism section that is provided with a lifting portion for lifting honeycomb structures and a shelf plate; an actual load value measuring section that measures an actual load value; a total load value calculating section that adds up the plurality of measured actual load value; a total load value determining section that compares a standard total weight value of the honeycomb structures and the shelf plate to the total load value and determines whether to satisfy a total load value determining condition; an actual load value determining section that compares the actual load value to the specified load value and determines whether to satisfy an actual load value determining condition; and a shelf-plate crack determining section that determines that the shelf plate is cracked when the total load value determining condition or the actual load value determining condition is not satisfied.

1. A shelf-plate crack detecting method comprising:
a lifting process of lifting a shelf plate mounted with honeycomb structures using a plurality of lifting portions; an actual load value measuring process of measuring actual load values applied to the lifting portions by which the shelf plate is lifted, for each of the lifting portions; a total load value calculating process of adding up the plurality of measured actual load values and calculating a total load value; a total load value determining process of comparing a prescribed standard total weight value related to a total weight of the honeycomb structures and the shelf plate to the calculated total load value and determining whether the standard total weight value coincides with the total load value; an actual load value determining process of comparing a specified load value to the actual load value and determining whether the actual load value is equal to or larger than the specified load value, the specified load value being obtained by multiplying the standard total weight value by a specified coefficient specified in advance depending on the number of the lifting portions; and a shelf-plate crack determining process of determining that the shelf plate mounted with the honeycomb structures is cracked when at least one condition of the total load value determining process or the actual load value determining process is not satisfied.
