ABSTRACT:
Apparatus for detecting whether the top panel of a container cap is properly depressed as capped containers are conveyed along a travel path. The apparatus is of the type comprising a floating shoe disposed over the travel path and carrying a proximity sensor. The shoe includes a reference portion arranged to be contacted by the caps to conform the shoe to the orientation of the cap. The floating shoe is mounted for lateral movement and includes guide flanges. The flanges extend generally fore-to-aft and are arranged to be contacted by the caps to shift the shoe laterally so as to position the proximity sensor over the same portions of successive caps. If caps of non-metallic material are being sensed, a metal spring member is carried by the shoe and is arranged to be contacted by the top panel of each cap and assume a spacing from the proximity sensor in accordance with the degree of depression of the top panel. The proximity sensor is directed toward the spring member to sense the latter.
