<p><P>PROBLEM TO BE SOLVED: To provide a seaming inspection apparatus and an inspection method for a metallic can end, capable of accurately performing seaming inspection with a simple configuration. <P>SOLUTION: A seaming inspection method for a metallic can end comprises: forming a polar coordinate development image 112 from an image captured by a camera 32 (S4); identifying an inner flange edge 122 on an inner side face 61 of a seaming portion 3 (S5); identifying an outer flange edge 124 on an outer side face 62 of the seaming portion 3 (S6); determining whether or not a width dimension 131 from the inner flange edge 122 to the outer flange edge 124 is within a threshold value (S8); if the width dimension is within the threshold value, inspecting variations in the longitudinal direction respectively for an inner band width 161 of the inner side face 61 and an outer band width 162 of the outer side face 62 (S9); if the variation is large, setting a seaming failure flag (S10) and finishing inspection; and on the other hand, if the variation is small, resetting the seaming failure flag (S11) and finishing the inspection. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
